上行控制信道传输方法、装置及系统Uplink control channel transmission method, device and system

技术领域technical field

本发明实施例涉及通信技术，尤其涉及一种上行控制信道传输方法、装置及系统。Embodiments of the present invention relate to communication technologies, and in particular, to an uplink control channel transmission method, device, and system.

背景技术Background technique

长期演进(Long Term Evolution，简称LTE)系统中，为了支持物理下行共享数据信道(Physical Downlink Shared Channel，简称PDSCH)的自适应编码调制及混合自动重传等技术，用户设备(User Equipment，简称UE) 需通过物理上行控制信道(PhysicalUplink Control Channel，简称PUCCH) 或者物理上行共享信道(Physical Uplink SharedChannel，简称PUSCH)向网络设备反馈混合自动重传请求(Hybrid Automatic RepeatRequest，简称 HARQ)信息，其中包括确认应答(Acknowledgment，简称ACK)和否认应答(Negative Acknowledgement，简称NACK)，分别对应于承载在PDSCH 上的下行数据在UE侧是被正确接收到(ACK)还是没有正确接收到 (NACK)。另外，为了满足国际电信联盟对于第四代通信技术的峰值数据速率要求，在LTE的进一步演进和增强系统(LTE-Advanced，简称LTE-A) 中，引入了载波聚合(Carrier Aggregation，简称CA)技术，将两个或更多的成员载波(Component Carrier，简称CC)的频谱聚合在一起以得到更宽的传输带宽。In the Long Term Evolution (LTE for short) system, in order to support technologies such as adaptive coding modulation and hybrid automatic retransmission of Physical Downlink Shared Channel (PDSCH), User Equipment (UE for short) ) It is necessary to feed back the Hybrid Automatic Repeat Request (HARQ) information to the network device through the Physical Uplink Control Channel (PUCCH) or the Physical Uplink Shared Channel (PUSCH), including confirmation Acknowledgment (ACK for short) and Negative Acknowledgement (NACK for short) respectively correspond to whether the downlink data carried on the PDSCH is correctly received (ACK) or not correctly received (NACK) at the UE side. In addition, in order to meet the peak data rate requirements of the International Telecommunication Union for the fourth generation communication technology, Carrier Aggregation (CA) is introduced in the LTE Further Evolution and Enhancement System (LTE-Advanced, LTE-A for short). A technology that aggregates the spectrums of two or more component carriers (Component Carriers, CC for short) together to obtain a wider transmission bandwidth.

现有的CA技术中基站(Evolved Node B，简称eNodeB)针对UE配置主小区(PrimaryCell，简称PCell)和辅小区(SecondaryCell，简称SCell)， UE通过承载在PUCCH上的HARQ-ACK信息对所有服务小区(Serving Cell，简称SC)(包括PCell和SCell)的下行子帧中传输的承载在PDSCH上的下行数据进行反馈，而该HARQ-ACK信息只在PCell的上行载波上传输。In the existing CA technology, a base station (Evolved Node B, eNodeB for short) configures a primary cell (Primary Cell, PCell for short) and a secondary cell (Secondary Cell, SCell for short) for the UE, and the UE uses the HARQ-ACK information carried on the PUCCH to all services. The downlink data carried on the PDSCH transmitted in the downlink subframe of a cell (Serving Cell, SC for short) (including PCell and SCell) is fed back, and the HARQ-ACK information is only transmitted on the uplink carrier of the PCell.

这样一来，在有宏网覆盖的小小区部署场景下，为保证一定的移动性能，可以同时有大量的UE选择PCell的上行载波进行HARQ-ACK反馈，将使得PCell的上行载波发送PUCCH的负载过重，特别是当PCell的上行载波数较少、载波带宽较小的情况下，可能使得PCell的上行载波无法再承载 PUSCH信道的上行数据传输。In this way, in the deployment scenario of small cells covered by the macro network, in order to ensure a certain mobility performance, a large number of UEs can select the uplink carrier of the PCell for HARQ-ACK feedback at the same time, which will make the uplink carrier of the PCell send the PUCCH load. If it is too heavy, especially when the number of uplink carriers of the PCell is small and the carrier bandwidth is small, the uplink carrier of the PCell may no longer be able to carry the uplink data transmission of the PUSCH channel.

具体实施方式Detailed ways

现有技术中，在载波聚合的场景下，UE都在Pcell的上行载波上发送PUCCH，PUCCH信道传输的功率控制命令字都来自于Pcell上PDCCH中的对PUCCH的TPC命令字段的信息。网络设备对PUCCH的TPC命令字中携带的功控消息不区分UE发送PUCCH的是格式(format)1a/1b还是PUCCH format 3，UE在使用TPC命令字调整PUCCH发射功率的时候根据不同的发射格式体现一定的发射功率偏差。In the prior art, in the carrier aggregation scenario, the UE transmits the PUCCH on the uplink carrier of the Pcell, and the power control command words transmitted by the PUCCH channel all come from the information in the TPC command field for the PUCCH in the PDCCH on the Pcell. The network device does not distinguish whether the UE sends the PUCCH in format 1a/1b or PUCCH format 3 for the power control message carried in the TPC command word of the PUCCH. When the UE uses the TPC command word to adjust the PUCCH transmission power, it is based on different transmission formats Reflect a certain transmit power deviation.

为卸载Pcell的上行载波的PUCCH负载，可以在除Pcell的其它一个或一个以上的Scell上也发送PUCCH信道，即在Scell上承载PUCCH信道，假设这个除Pcell外可以承载PUCCH信道的Cell叫做PUCCH-Scell。如果UE 只在Pcell的下行载波上检测到PDSCH传输，则UE使用PUCCH format 1a/1b 来回复HARQ-ACK，PUCCH format 1a/1b的传输资源与调度PDSCH的PDCCH资源位置对应，或者用Pcell上配置的SPS反馈资源；而如果UE在除Pcell外的其他任何一个Scell的下行载波上检测到PDSCH传输，UE使用PUCCH format 3反馈HARQ-ACK，PUCCH format 3的资源由eNodeB通过 Scell的PDCCH的TPC命令字段的信息指示，可以是在PUCCH-Scell的上行载波上，从而达到卸载Pcell中PUCCH负载的目的。In order to offload the PUCCH load of the uplink carrier of the Pcell, the PUCCH channel can also be sent on one or more Scells other than the Pcell, that is, the PUCCH channel is carried on the Scell. Scell. If the UE only detects PDSCH transmission on the downlink carrier of the Pcell, the UE uses the PUCCH format 1a/1b to reply the HARQ-ACK, and the transmission resources of the PUCCH format 1a/1b correspond to the PDCCH resource positions of the scheduled PDSCH, or use the PUCCH format 1a/1b to configure the PDCCH resource location. If the UE detects PDSCH transmission on the downlink carrier of any other Scell except Pcell, the UE uses PUCCH format 3 to feed back HARQ-ACK, and the resources of PUCCH format 3 are ordered by the eNodeB through the TPC of the PDCCH of the Scell. The information indication of the field may be on the uplink carrier of the PUCCH-Scell, so as to achieve the purpose of unloading the PUCCH load in the Pcell.

但是，由于PUCCH format 1a/1b的PUCCH信道和PUCCH format 3的 PUCCH信道传输的功率控制命令字都来自Pcell上PDCCH中的TPC命令字段，这样，如果eNodeB在Pcell和除Pcell外的其他Cell的下行载波上为UE 传输了下行数据，但是到达UE后，UE并没有检测到除Pcell外其他Cell的下行载波上的数据，这种情况下，UE会误以为eNodeB只在Pcell的下行载波上对自己有数据传输而在Pcell的上行载波上使用PUCCH format 1a/1b反馈HARQ-ACK。结果，eNodeB在Pcell的PDCCH(包括调度PDSCH的 PDCCH或其它携带下行控制信息(Downlink Control Information，简称DCI) format3/3A的PDCCH)中对PUCCH的TPC命令字段原本是用来调整 PUCCH-Scell上PUCCH的发射功率，UE却用该功率控制消息调整了Pcell 上PUCCH format 1a/1b的PUCCH信道的发射功率，导致了对PUCCH发射功率错误控制的后果。However, since the power control command words transmitted by the PUCCH channel of PUCCH format 1a/1b and the PUCCH channel of PUCCH format 3 all come from the TPC command field in the PDCCH on the Pcell, if the eNodeB is in the downlink of the Pcell and other Cells except the Pcell The downlink data is transmitted for the UE on the carrier, but after reaching the UE, the UE does not detect the data on the downlink carriers of other Cells except the Pcell. In this case, the UE will mistakenly think that the eNodeB is only on the downlink carrier of the Pcell. There is data transmission and the HARQ-ACK is fed back using PUCCH format 1a/1b on the uplink carrier of the Pcell. As a result, the TPC command field of the eNodeB to the PUCCH in the PDCCH of the Pcell (including the PDCCH scheduling PDSCH or other PDCCH carrying Downlink Control Information (DCI) format 3/3A) was originally used to adjust the PUCCH on the PUCCH-Scell However, the UE uses the power control message to adjust the transmit power of the PUCCH channel of PUCCH format 1a/1b on the Pcell, which leads to the consequence of erroneous control of the PUCCH transmit power.

因此，本发明的技术方案在于，UE可以在除Pcell的其他上行载波上传输PUCCH信道，通过eNodeB在各Cell的下行数据的调度情况动态地确定 PUCCH的发送格式和资源索引，并且在PDCCH信道分别控制所在小区上行载波上PUCCH的发射功率。利用该机制可以合理分配PUCCH信道的传输资源，解决了PUCCH功率控制错误的问题，也解决了Pcell的上行载波 PUCCH负载过重的问题，同时保证了PUCCH信道传输的性能。Therefore, the technical solution of the present invention is that the UE can transmit the PUCCH channel on other uplink carriers except the Pcell, dynamically determine the transmission format and resource index of the PUCCH according to the scheduling situation of the downlink data of each Cell by the eNodeB, and separately on the PDCCH channel Controls the transmit power of the PUCCH on the uplink carrier of the cell where it is located. Using this mechanism, the transmission resources of the PUCCH channel can be allocated reasonably, the problem of PUCCH power control error is solved, and the problem of the PUCCH overload of the uplink carrier of the Pcell is also solved, and the performance of the PUCCH channel transmission is guaranteed at the same time.

为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments These are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

图1为本发明上行控制信道传输方法实施例一的流程图，如图1所示，本实施例的方法可以包括：FIG. 1 is a flowchart of Embodiment 1 of an uplink control channel transmission method according to the present invention. As shown in FIG. 1 , the method in this embodiment may include:

步骤101、确定可用于发送混合自动重传请求HARQ-ACK反馈信息的物理上行控制信道PUCCH的第一上行载波和第二上行载波；Step 101, determining the first uplink carrier and the second uplink carrier of the physical uplink control channel PUCCH that can be used to send the hybrid automatic repeat request HARQ-ACK feedback information;

本实施例的执行主体可以是UE。所述第一上行载波对应第一小区，所述第二上行载波对应第二小区，UE在明确哪个是第一上行载波，那个是第二上行载波，以及第一上行载波对应的第一小区和第二上行载波对应的第二小区，在后续的操作中就可以准确的获取到发送HARQ-ACK反馈信息的 PUCCH资源。The executive body of this embodiment may be a UE. The first uplink carrier corresponds to the first cell, the second uplink carrier corresponds to the second cell, and the UE is determining which is the first uplink carrier, which is the second uplink carrier, and the first cell and the first cell corresponding to the first uplink carrier. The second cell corresponding to the second uplink carrier can accurately obtain the PUCCH resource for sending the HARQ-ACK feedback information in subsequent operations.

步骤102、在下行载波上检测下行数据获得检测结果；Step 102: Detect downlink data on the downlink carrier to obtain a detection result;

本实施例中，所述下行载波包括属于第一小区的第一下行载波和/或属于第二小区的第二下行载波和/或至少一个属于其它小区的下行载波，所述下行数据为第一类下行数据或者第二类下行数据，所述第一类下行数据为由物理下行控制信道PDCCH调度的物理下行共享数据信道PDSCH或者释放下行半静态调度SPS的PDCCH，所述第二类下行数据为没有PDCCH调度的 PDSCH。In this embodiment, the downlink carrier includes a first downlink carrier belonging to a first cell and/or a second downlink carrier belonging to a second cell and/or at least one downlink carrier belonging to other cells, and the downlink data is the first downlink carrier One type of downlink data or the second type of downlink data, the first type of downlink data is the physical downlink shared data channel PDSCH scheduled by the physical downlink control channel PDCCH or the PDCCH that releases the downlink semi-persistently scheduled SPS, the second type of downlink data For PDSCH without PDCCH scheduling.

需要说明的是，在本发明的所有实施例中，UE在下行载波上检测下行数据获得的检测结果，包括UE是否在下行载波上检测到有下行数据传输和/或检测到的下行数据传输是否传输正确。It should be noted that, in all embodiments of the present invention, the detection results obtained by the UE detecting downlink data on the downlink carrier include whether the UE detects that there is downlink data transmission on the downlink carrier and/or whether the detected downlink data transmission is Transmission is correct.

现有的CA技术中eNodeB针对UE配置PCell和SCell，为保证UE在 SCell内的移动性能，UE通过承载在PUCCH上的HARQ-ACK信息对所有 SC(包括PCell和SCell)的下行子帧中传输的承载在PDSCH上的下行数据进行反馈，通常在一个子帧内有多个下行载波上承载有下行数据，而UE只在PCell的PUCCH上反馈HARQ-ACK信息，3GPP协议中新增了2个 PUCCH格式(format)以支持载波聚合：一个是带信道选择的PUCCH format 1b(PUCCH format 1b withchannel selection)：使用PUCCH format 1b携带的 2比特的HARQ-ACK信息，再通过信道选择来确定发送HARQ-ACK信息的 PUCCH资源，这种格式只支持不超过4比特HARQ-ACK信息且不多于2个 SC的场景；另一个是PUCCH format 3：可支持至多5个SC且UE在每个SC 都配置了多入多出技术(Multiple-Input Multiple-Output，简称MIMO)的场景，PUCCH format 3也能够支持2个SC的场景，具体是使用PUCCH format 3还是PUCCH format 1b withchannel selection取决于eNodeB的配置。In the existing CA technology, the eNodeB configures PCell and SCell for the UE. In order to ensure the mobility performance of the UE in the SCell, the UE transmits the HARQ-ACK information carried on the PUCCH to the downlink subframes of all SCs (including PCell and SCell). The downlink data carried on the PDSCH is fed back. Usually, there are multiple downlink carriers in a subframe that carry the downlink data, and the UE only feeds back the HARQ-ACK information on the PUCCH of the PCell. The 3GPP protocol added 2 PUCCH format (format) to support carrier aggregation: one is PUCCH format 1b with channel selection (PUCCH format 1b with channel selection): use the 2-bit HARQ-ACK information carried by PUCCH format 1b, and then determine the transmission of HARQ- PUCCH resource for ACK information, this format only supports scenarios with no more than 4 bits of HARQ-ACK information and no more than 2 SCs; the other is PUCCH format 3: it can support up to 5 SCs and the UE is configured in each SC For multiple-input multiple-output (MIMO) scenarios, PUCCH format 3 can also support two SC scenarios. Whether to use PUCCH format 3 or PUCCH format 1b with channel selection depends on the eNodeB configuration.

本实施例中，UE在下行载波上检测网络设备发送的下行数据，对于UE 来讲，网络设备发送的数据可以是从第一小区的第一下行载波上发送的，也可以是在第二小区的第二下行载波上发送的，还可以是在其它小区的下行载波上发送的，这里的其它小区是指除第一小区和第二小区外的小区，由于 UE并不确定下行数据具体通过哪个下行载波发送，因此UE需要在各个下行载波上进行检测以防数据丢失。这里所述UE在下行载波上检测网络设备发送的下行数据分为两类，一类是有物理下行控制信道(Physical Downlink ControlChannel，简称PDCCH)调度的PDSCH或释放下行半静态调度(Semi PersistentSchedulingv，简称SPS)的PDCCH，前者可以认为是动态调度状态下，每次网络设备发送下行数据都会在在下行载波的PDCCH上携带上 PDSCH的资源信息，后者网络设备在激活下行SPS时向UE发送一个 PDCCH，告知UE在后续的一段时间内网络设备会周期性地在固定的资源上发送PDSCH，然后网络设备在释放下行SPS时再向UE发送一个PDCCH，告知UE下行SPS调度方式结束，UE无论是收到带有PDCCH的PDSCH还是收到释放下行SPS的PDCCH都需要向网络设备反馈接收结果，即 HARQ-ACK反馈信息；另一类是没有PDCCH调度的PDSCH，可以认为这一类数据即下行SPS调度，网络设备在激活下行SPS时已经预先分配了 PDSCH的资源，因此在后续一段时间内，网络设备将会周期性地使用相同的资源发送下行数据，此时，UE也是在固定的位置上检测下行数据，在这个过程中的PDSCH不需要再另外通过PDCCH进行调度，UE同样要向网络设备反馈HARQ-ACK信息。In this embodiment, the UE detects the downlink data sent by the network device on the downlink carrier. For the UE, the data sent by the network device may be sent from the first downlink carrier of the first cell, or may be sent on the second downlink carrier. It is sent on the second downlink carrier of the cell, or it can be sent on the downlink carrier of other cells. The other cells here refer to cells other than the first cell and the second cell. Which downlink carrier to send, so the UE needs to detect on each downlink carrier to prevent data loss. Here, the UE detects the downlink data sent by the network device on the downlink carrier into two categories, one is PDSCH scheduled by Physical Downlink Control Channel (PDCCH) or release downlink semi-persistent scheduling (Semi Persistent Scheduling, referred to as PDCCH) SPS) PDCCH, the former can be considered as a dynamic scheduling state, every time the network device sends downlink data, it will carry the PDSCH resource information on the PDCCH of the downlink carrier, and the latter network device when activating the downlink SPS Send a PDCCH to the UE , inform the UE that the network device will periodically send PDSCH on fixed resources in the following period of time, and then the network device will send another PDCCH to the UE when the downlink SPS is released to inform the UE that the downlink SPS scheduling mode is over. To the PDSCH with PDCCH or the PDCCH that releases the downlink SPS, it is necessary to feed back the reception result to the network device, that is, the HARQ-ACK feedback information; the other type is the PDSCH without PDCCH scheduling, which can be considered as the downlink SPS scheduling. , the network device has pre-allocated PDSCH resources when activating the downlink SPS. Therefore, in the following period of time, the network device will periodically use the same resources to send downlink data. At this time, the UE also detects downlink data at a fixed location. In this process, the PDSCH does not need to be scheduled through the PDCCH, and the UE also needs to feed back the HARQ-ACK information to the network device.

步骤103、根据所述检测结果，确定发送所述HARQ-ACK反馈信息的所述PUCCH的格式、PUCCH的资源索引。Step 103: Determine the format of the PUCCH and the resource index of the PUCCH for sending the HARQ-ACK feedback information according to the detection result.

本实施例中，UE根据在下行载波上检测下行数据的结果，即UE可能在其它小区的下行载波上检测到下行数据，或者只在第一下行载波和/或第二下行载波上检测到下行数据。根据上述检测结果，UE确定自己发送 HARQ-ACK反馈信息的PUCCH的格式和资源索引，这里承载所述PUCCH 的上行载波包括属于所述第一小区的第一上行载波和/或属于所述第二小区的第二上行载波，也就是说，UE收到第一小区、第二小区和/或其它小区的下行载波上的下行数据后，可以有两个发送HARQ-ACK反馈信息的上行载波，即第一小区的第一上行载波和第二小区的第二上行载波，在这两个上行载波上可以确定出相应的PUCCH格式、资源索引，使得在该PUCCH资源上携带HARQ-ACK反馈信息。In this embodiment, according to the result of detecting downlink data on the downlink carrier, the UE may detect downlink data on the downlink carriers of other cells, or only detect the downlink data on the first downlink carrier and/or the second downlink carrier Downlink data. According to the above detection result, the UE determines the format and resource index of the PUCCH on which it sends the HARQ-ACK feedback information, where the uplink carrier carrying the PUCCH includes the first uplink carrier belonging to the first cell and/or the second uplink carrier belonging to the second cell. The second uplink carrier of the cell, that is, after the UE receives downlink data on the downlink carriers of the first cell, the second cell and/or other cells, there may be two uplink carriers for sending HARQ-ACK feedback information, namely The first uplink carrier of the first cell and the second uplink carrier of the second cell can determine the corresponding PUCCH format and resource index on these two uplink carriers, so that the HARQ-ACK feedback information is carried on the PUCCH resource.

本实施例，通过UE在第一上行载波和/或第二上行载波上发送 HARQ-ACK反馈信息，以对多个小区的下行数据进行反馈，减轻上行载波的负载，通过eNodeB在各Cell的下行数据调度情况和指示动态地确定 PUCCH的发送格式和资源，利用该机制可以合理分配PUCCH format3信道的传输资源，提高了系统通信性能。In this embodiment, the UE sends HARQ-ACK feedback information on the first uplink carrier and/or the second uplink carrier to feed back the downlink data of multiple cells and reduce the load of the uplink carrier. The transmission format and resources of PUCCH can be determined dynamically according to the data scheduling situation and instruction. By using this mechanism, the transmission resources of PUCCH format 3 channel can be allocated reasonably, which improves the communication performance of the system.

进一步的，上述方法实施例的步骤103根据所述检测结果，确定发送所述HARQ-ACK反馈信息的所述PUCCH的格式、PUCCH的资源索引，具体的实现方法可以是：如果在所述至少一个属于其它小区的下行载波上检测到所述下行数据，则确定发送所述HARQ-ACK反馈信息的所述PUCCH的格式为第一格式，所述第一格式为PUCCH格式format 3；如果只在所述第一小区的所述第一下行载波和/或所述第二小区的所述第二下行载波上检测到所述下行数据，则确定发送所述HARQ-ACK反馈信息的所述PUCCH的格式为第二格式，所述第二格式为PUCCH格式format 1a或者format 1b。Further, step 103 of the above method embodiment determines the format of the PUCCH and the resource index of the PUCCH for sending the HARQ-ACK feedback information according to the detection result. The specific implementation method may be: if the at least one If the downlink data is detected on the downlink carriers belonging to other cells, it is determined that the format of the PUCCH for sending the HARQ-ACK feedback information is the first format, and the first format is the PUCCH format format 3; If the downlink data is detected on the first downlink carrier of the first cell and/or the second downlink carrier of the second cell, determine the PUCCH for sending the HARQ-ACK feedback information. The format is the second format, and the second format is the PUCCH format format 1a or format 1b.

具体来讲，如果UE在至少一个属于其它小区的下行载波上检测到下行数据那么不管在第一下行载波和第二下行载波上是否检测到下行数据，都会将发送HARQ-ACK反馈信息的PUCCH的格式确定为PUCCH format 3；如果UE只在第一小区的第一下行载波和/或第二小区的第二下行载波上检测到所述下行数据，那么UE会将发送HARQ-ACK反馈信息的PUCCH的格式确定为PUCCH format 1a或者PUCCH format 1b。这是UE在确定PUCCH的格式时需要遵守的原则，这也是UE和网络设备预先达成共识的。Specifically, if the UE detects downlink data on at least one downlink carrier belonging to another cell, regardless of whether downlink data is detected on the first downlink carrier and the second downlink carrier, the UE will send the PUCCH of the HARQ-ACK feedback information. The format is determined to be PUCCH format 3; if the UE detects the downlink data only on the first downlink carrier of the first cell and/or the second downlink carrier of the second cell, the UE will send HARQ-ACK feedback information The format of the PUCCH is determined to be PUCCH format 1a or PUCCH format 1b. This is the principle that the UE needs to observe when determining the format of the PUCCH, which is also agreed by the UE and the network device in advance.

进一步的，在上述方法实施例的步骤101之前，还包括接收资源配置信息，根据所述资源配置信息确定通过PUCCH format 3发送所述HARQ-ACK 反馈信息。具体来讲，UE在接收到网络设备配置的资源配置信息后，根据该资源配置信息可以获知网络设备是否给自己配置了PUCCH format 3资源，自己在发送HARQ-ACK反馈信息时是否可以使用PUCCH format3格式。Further, beforestep 101 of the above method embodiment, the method further includes receiving resource configuration information, and determining, according to the resource configuration information, to send the HARQ-ACK feedback information through PUCCH format 3. Specifically, after receiving the resource configuration information configured by the network device, the UE can learn whether the network device has configured PUCCH format 3 resources for itself according to the resource configuration information, and whether it can use PUCCH format 3 when sending HARQ-ACK feedback information. Format.

下面采用几个具体的实施例，对图1所示方法实施例的技术方案进行详细说明。The technical solution of the method embodiment shown in FIG. 1 will be described in detail below by using several specific embodiments.

图2为本发明上行控制信道传输方法实施例二的流程图，如图2所示，本实施例的方法可以包括：FIG. 2 is a flowchart of Embodiment 2 of an uplink control channel transmission method according to the present invention. As shown in FIG. 2 , the method in this embodiment may include:

步骤201、在至少一个属于其它小区的下行载波上检测到下行数据；Step 201: Detect downlink data on at least one downlink carrier belonging to another cell;

本实施例的执行主体为UE。UE在至少一个属于其它小区的下行载波上检测到网络设备发送的下行数据，这里不限制UE是否在第一下行载波和第二下行载波上检测到数据。至少一个属于其它小区的下行载波表示UE检测到的下行数据可以是其它一个小区的下行载波，也可以是其它多个小区的下行载波，此处不做具体限定。The execution subject of this embodiment is the UE. The UE detects downlink data sent by the network device on at least one downlink carrier belonging to another cell, and whether the UE detects data on the first downlink carrier and the second downlink carrier is not limited here. At least one downlink carrier belonging to another cell indicates that the downlink data detected by the UE may be the downlink carrier of one other cell, or may be the downlink carrier of multiple other cells, which is not specifically limited here.

步骤202、根据检测到的下行数据的下行载波以及下行数据，采用第一方案确定发送HARQ-ACK反馈信息的PUCCH的格式、PUCCH的资源索引。Step 202: According to the detected downlink carrier and downlink data of the downlink data, adopt the first scheme to determine the format of the PUCCH for sending the HARQ-ACK feedback information and the resource index of the PUCCH.

本实施例中，UE在其它小区的下行载波上检测到了下行数据，这里的下行数据通常是指由PDCCH调度的PDSCH，在这种情况下，UE确定发送 HARQ-ACK反馈信息的PUCCH的格式为PUCCH format 3，第一方案包括：In this embodiment, the UE detects downlink data on the downlink carriers of other cells. The downlink data here usually refers to the PDSCH scheduled by the PDCCH. In this case, the UE determines that the format of the PUCCH for sending the HARQ-ACK feedback information is PUCCH format 3, the first scheme includes:

根据所述网络设备预先配置的所述PUCCH format 3资源确定所述第一小区和所述第二小区中可用于发送所述HARQ-ACK反馈信息的所有所述 PUCCH format 3资源；根据在所述至少一个属于其它小区的下行载波上检测到的所述PDSCH的所述PDCCH中的传输功率控制(Transmission Power Control，简称TPC)命令字段的信息获取发送所述HARQ-ACK反馈信息的所述PUCCH的资源索引。Determine all the PUCCH format 3 resources that can be used to send the HARQ-ACK feedback information in the first cell and the second cell according to the PUCCH format 3 resources preconfigured by the network device; The information of the Transmission Power Control (Transmission Power Control, TPC for short) command field in the PDCCH of the PDSCH detected on at least one downlink carrier belonging to another cell obtains the information of the PUCCH that sends the HARQ-ACK feedback information. Resource index.

具体来讲，网络设备预先为UE配置了至少两个可用的PUCCH format 3 资源，UE根据网络设备的配置信息确定这些PUCCH的可用的资源索引，然后根据在其它小区的下行载波上检测到的调度PDSCH的PDCCH中的信息确定PUCCH的资源索引，该信息具体的即PDCCH中的TPC命令字段的信息，该字段是一个复用字段，可以作为上行功控信息，也可以作为资源索引信息，在PUCCH format 3中将该字段是作为资源指示来使用的，而且 PUCCH的资源索引对应的PUCCH资源可以是第一上行载波的，也可以是第二上行载波的，UE根据TPC命令字段的信息也同时确定了发送PUCCH的上行载波。UE在确定了PUCCH的格式以及资源索引后，就可以将下行载波上的数据的检测结果通过该PUCCH资源反馈给网络设备了，需要说明的是，UE如果只在其它小区的下行载波上检测到下行数据，则在PUCCH format 3中只需要在相应的比特位上填写该下行载波的检测结果，如果UE还在第一下行载波和/或第二下行载波上检测到下行数据，则在PUCCH format 3中UE将在所有下行载波的检测结果都填写在相应的比特位上反馈给网络设备，这样一来只需要一个PUCCH资源就可以将所有检测结果携带上，与同时在第一上行载波和第二上行载波上反馈PUCCH format 3相比，减少了反馈占用的资源，也提高了PUCCH foramt 3的性能。Specifically, the network device pre-configures at least two available PUCCH format 3 resources for the UE, and the UE determines the available resource indexes of these PUCCHs according to the configuration information of the network device, and then according to the scheduling detected on the downlink carriers of other cells The information in the PDCCH of the PDSCH determines the resource index of the PUCCH. Specifically, the information is the information of the TPC command field in the PDCCH. This field is a multiplexing field, which can be used as uplink power control information or resource index information. In format 3, this field is used as a resource indication, and the PUCCH resource corresponding to the PUCCH resource index can be either the first uplink carrier or the second uplink carrier, and the UE also determines according to the information in the TPC command field. the uplink carrier that transmits the PUCCH. After the UE determines the PUCCH format and resource index, it can feed back the detection result of the data on the downlink carrier to the network device through the PUCCH resource. It should be noted that if the UE only detects the data on the downlink carrier of other cells Downlink data, then in PUCCH format 3, only the detection result of the downlink carrier needs to be filled in the corresponding bits. If the UE also detects downlink data on the first downlink carrier and/or the second downlink carrier, then the PUCCH In format 3, the UE fills in the detection results of all downlink carriers in the corresponding bits and feeds them back to the network device, so that only one PUCCH resource is needed to carry all the detection results, and the first uplink carrier and Compared with the feedback of PUCCH format 3 on the second uplink carrier, the resources occupied by the feedback are reduced, and the performance of the PUCCH foramt 3 is also improved.

本实施例，通过UE在第一上行载波或第二上行载波上发送PUCCH format 3，以对多个小区的下行数据进行反馈，不但减轻上行载波的负载，解决现有技术中UE只在PCell的PUCCH上反馈HARQ-ACK信息导致PCell 的上行载波负载过重的问题，而且将多个信息通过一个PUCCH资源反馈提高传输性能。In this embodiment, the UE sends PUCCH format 3 on the first uplink carrier or the second uplink carrier to feed back the downlink data of multiple cells, which not only reduces the load of the uplink carrier, but also solves the problem that in the prior art, the UE only operates on the PCell. Feedback of HARQ-ACK information on the PUCCH leads to the problem that the uplink carrier of the PCell is overloaded, and the transmission performance is improved by feeding back multiple pieces of information through one PUCCH resource.

图3为本发明上行控制信道传输方法实施例三的流程图，如图3所示，本实施例的方法可以包括：FIG. 3 is a flowchart of Embodiment 3 of an uplink control channel transmission method according to the present invention. As shown in FIG. 3 , the method in this embodiment may include:

步骤301、在第一下行载波和第二下行载波上都检测到下行数据且没有在属于其它小区的下行载波上检测到下行数据；Step 301: Downlink data is detected on both the first downlink carrier and the second downlink carrier, and downlink data is not detected on downlink carriers belonging to other cells;

Besides, the UE does not detect downlink data on the downlink carrier of any other cell.

步骤302、接收网络设备发送的方案配置信息，并根据方案配置信息确定是否采用第二方案确定发送HARQ-ACK反馈信息的PUCCH的格式、 PUCCH的资源索引；Step 302: Receive the scheme configuration information sent by the network device, and determine whether to adopt the second scheme to determine the format of the PUCCH and the resource index of the PUCCH for sending the HARQ-ACK feedback information according to the scheme configuration information;

This embodiment is one of the methods, and whether the UE adopts the method in this embodiment, the network The device will notify the UE, that is, send the scheme configuration information to the UE, and then the UE determines which scheme to use to determine the format of the PUCCH and the resource index of the PUCCH according to the scheme configuration information. It should be noted that, step 302 may not be a necessary step, and here indicates an implementation method of the present invention, and is not limited to other forms of implementation.

步骤303、根据检测到的下行数据的下行载波以及下行数据，采用第二方案确定发送HARQ-ACK反馈信息的PUCCH的格式、PUCCH的资源索引。Step 303: According to the detected downlink carrier and downlink data of the downlink data, adopt the second scheme to determine the format of the PUCCH for sending the HARQ-ACK feedback information and the resource index of the PUCCH.

Feeding back the PUCCH resource of the detection result of the second type of downlink data and the latest information of the TPC command field in the PDCCH indicating the downlink SPS activation determines that the first uplink carrier can be used to send the HARQ- the PUCCH resource of the ACK feedback information; in the second cell, determine all the available resources for sending the HARQ-ACK feedback information on the second uplink carrier according to the PDCCH in the first type of downlink data The PUCCH resource, or, according to at least one of the PUCCH resources configured by the network device on the second uplink carrier that can be used to feed back the detection result of the second type of downlink data and the latest one indicating the downlink SPS activation The information in the TPC command field in the PDCCH of the PDCCH determines the PUCCH resource available for sending the HARQ-ACK feedback information on the second uplink carrier.

具体来讲，第二方案中，UE可以通过PUCCH format 1b的格式来反馈检测结果，具体的该格式可以是PUCCH format 1b with channel selection，然后 UE根据网络设备预先配置的信道选择方案来确定最终是在哪个上行载波上发送PUCCH format 1b，3GPP协议中规定了信道选择方案的内容，下面举例说明该方案的实现过程：Specifically, in the second solution, the UE can feed back the detection result through the format of PUCCH format 1b, and the specific format can be PUCCH format 1b with channel selection, and then the UE determines the final On which uplink carrier to send PUCCH format 1b, the content of the channel selection scheme is specified in the 3GPP protocol. The following example illustrates the implementation process of the scheme:

步骤一、UE根据表1以及上述方法确定A个可用于发送HARQ-ACK反馈信息的PUCCH资源，表1为TB和HARQ-ACK反馈信息的映射表，该 PUCCH资源是第一小区的第一上行载波的资源和第二小区的第二上行载波的资源，可以认为A＝在第一小区上配置的传输模式最多支持的传输块 (Transport Block，简称TB)数+在第二小区上配置的传输模式最多支持的TB数。需要说明的是，表1是一个示范，可以根据相同的原则设计其他形式的表。Step 1. The UE determines A PUCCH resources that can be used to send HARQ-ACK feedback information according to Table 1 and the above method. Table 1 is a mapping table of TB and HARQ-ACK feedback information, and the PUCCH resource is the first uplink of the first cell. The resources of the carrier and the resources of the second uplink carrier of the second cell can be considered as A = the maximum number of transport blocks (Transport Block, TB for short) supported by the transmission mode configured on the first cell + the transmission configured on the second cell The maximum number of terabytes supported by the mode. It should be noted that Table 1 is an example, and other forms of tables can be designed according to the same principle.

表1Table 1

其中，HARQ-ACK(j)表示对应于第一小区或第二小区中的TB需要进行 HARQ-ACK反馈，因此根据各小区中配置的传输模式最多支持的TB块数，即可确定有多少个可用于发送HARQ-ACK反馈信息的PUCCH资源。Among them, HARQ-ACK(j) indicates that HARQ-ACK feedback is required for the TB corresponding to the first cell or the second cell. Therefore, according to the maximum number of TB blocks supported by the transmission mode configured in each cell, the number of TB blocks can be determined. PUCCH resources available for sending HARQ-ACK feedback information.

以A＝3的情况为例进行说明，UE根据传输模式的配置情况，可以获知在A＝3的情况下，在第一服务小区中有两个可用的PUCCH资源，在第二服务小区中有一个可用的PUCCH资源。如果UE检测到的是第一类下行数据，则发送HARQ-ACK(0)的PUCCH的资源索引通过

计算获取，发送HARQ-ACK(1)的PUCCH的资源索引

通过

计算获取，其中，n_CCE为在所述第一下行载波或所述第二下行载波上，调度的所述PDSCH的所述PDCCH的第一个控制信道元素CCE的序号或者所述释放下行SPS的PDCCH的第一个CCE的序号，

为网络设备配置的对应该载波的参数；如果UE检测到的是第二类下行数据，则根据网络设备配置的在第一上行载波或第二上行载波上的可用于反馈第二类下行数据的检测结果的PUCCH资源和最近的一个指示下行SPS激活的PDCCH中的TPC命令字段的信息确定发送HARQ-ACK(0)的PUCCH的资源索引

和发送HARQ-ACK(1)的PUCCH的资源索引

Taking the case of A=3 as an example, according to the configuration of the transmission mode, the UE can know that in the case of A=3, there are two available PUCCH resources in the first serving cell, and there are two available PUCCH resources in the second serving cell. An available PUCCH resource. If the UE detects the first type of downlink data, it sends the resource index of the PUCCH of HARQ-ACK(0). pass

Calculate and obtain the resource index of the PUCCH that sends HARQ-ACK (1)

pass

Calculate and obtain, where n_CCE is the sequence number of the first control channel element CCE of the PDCCH of the PDSCH scheduled on the first downlink carrier or the second downlink carrier or the release downlink SPS the sequence number of the first CCE of the PDCCH,

The parameters corresponding to the carrier configured for the network device; if the UE detects the second type of downlink data, the parameters configured by the network device on the first uplink carrier or the second uplink carrier that can be used to feed back the second type of downlink data. The PUCCH resource of the detection result and the information in the TPC command field in the latest PDCCH indicating downlink SPS activation determine the resource index of the PUCCH for sending HARQ-ACK (0)

and the resource index of the PUCCH that sends the HARQ-ACK(1)

通过上述方法，UE可以获取到在第一小区和第二小区内对应于下行数据的PUCCH资源。需要说明的是，在第二方案中UE获取第一小区和第二小区内对应于下行数据的PUCCH资源的方法不限于上述方法。Through the above method, the UE can acquire PUCCH resources corresponding to downlink data in the first cell and the second cell. It should be noted that, in the second solution, the method for the UE to acquire the PUCCH resources corresponding to downlink data in the first cell and the second cell is not limited to the above method.

步骤二、UE根据表2-表4以及检测下行数据的结果确定最终发送 HARQ-ACK反馈信息的PUCCH资源，表2为A为2时信道选择配置表，表 3为A为3时信道选择配置表，表4为A为4时信道选择配置表。Step 2. The UE determines the PUCCH resource for finally sending the HARQ-ACK feedback information according to Table 2-Table 4 and the result of detecting the downlink data. Table 2 is the channel selection configuration table when A is 2, and Table 3 is the channel selection configuration when A is 3. Table 4 is the channel selection configuration table when A is 4.

表2Table 2

表3table 3

表4Table 4

以表3所示的A＝3的情况为例，如果UE检测到第一小区的TB1和TB2 以及第二小区的TB1，且三个TB都校验正确，根据表3第二行的配置，可以将PUCCH format 1b中的两个HARQ-ACK比特位b(0)b(1)填为1，1，通过与第一小区的TB2对应的那个PUCCH资源发送HARQ-ACK反馈信息；如果UE 检测到第一小区的TB1和TB2以及第二小区的TB1，且第一小区的TB1和 TB2校验正确，第二小区的TB1校验错误，根据表3第六行的配置，可以将 PUCCH format1b中的两个HARQ-ACK比特位b(0)b(1)填为1，1，通过与第一小区的TB1对应的那个PUCCH资源发送HARQ-ACK反馈信息，PUCCH的资源索引通过上述方法已经计算获得。Taking the case of A=3 shown in Table 3 as an example, if the UE detects TB1 and TB2 of the first cell and TB1 of the second cell, and all three TBs are verified correctly, according to the configuration in the second row of Table 3, The two HARQ-ACK bits b(0)b(1) in PUCCH format 1b can be filled with 1, 1, and the HARQ-ACK feedback information is sent through the PUCCH resource corresponding to TB2 of the first cell; if the UE detects To TB1 and TB2 of the first cell and TB1 of the second cell, and the verification of TB1 and TB2 of the first cell is correct, and the verification of TB1 of the second cell is incorrect, according to the configuration in the sixth row of Table 3, the PUCCH format1b can be The two HARQ-ACK bits b(0)b(1) are filled with 1, 1, and the HARQ-ACK feedback information is sent through the PUCCH resource corresponding to the TB1 of the first cell, and the resource index of the PUCCH has been calculated by the above method. get.

本实施例，通过信道选择方案使UE在第一上行载波或第二上行载波上发送PUCCHformat 1b，以对多个小区的下行数据进行反馈，不但减轻上行载波的负载，解决现有技术中UE只在PCell的PUCCH上反馈HARQ-ACK 信息导致PCell的上行载波负载过重的问题，而且将多个信息通过上行载波资源和HARQ-ACK反馈信息结合的方式一次将下行数据的检测结果反馈给网络设备提高传输性能。In this embodiment, the channel selection scheme enables the UE to send PUCCHformat 1b on the first uplink carrier or the second uplink carrier, so as to feed back the downlink data of multiple cells, which not only reduces the load of the uplink carrier, but also solves the problem that in the prior art, the UE only Feedback of HARQ-ACK information on the PUCCH of PCell leads to the problem that the uplink carrier of PCell is overloaded, and the detection result of downlink data is fed back to the network device at one time by combining multiple information with uplink carrier resources and HARQ-ACK feedback information. Improve transmission performance.

步骤401、在第一下行载波上检测到第一类下行数据；Step 401, detecting the first type of downlink data on the first downlink carrier;

本实施例的执行主体为UE。UE在第一下行载波上检测到第一类下行数据，即UE在第一小区的第一下行载波上检测到由PDCCH调度的PDSCH或者释放下行半SPS的PDCCH，这对这两种数据UE需要向网络设备反馈检测结果。The execution subject of this embodiment is the UE.

若网络设备使用两个天线时，根据公式

计算获取对应于第二天线端口的所述PUCCH的资源索引

If the network device uses two antennas, according to the formula

Calculate and obtain the resource index of the PUCCH corresponding to the second antenna port

具体来讲，第三方案中，UE可以通过PUCCH format 1a或PUCCH format 1b的格式来反馈检测结果，并且UE反馈检测结果所使用的PUCCH 资源和天线数相关，对应于第一天线端口的PUCCH的资源索引通过公式(1) 计算获取，本实施例的n_CCE为在第一下行载波上，调度的PDSCH的PDCCH 的第一个控制信道元素(Control Channel Element，简称CCE)的序号或者释放下行SPS的PDCCH的第一个CCE的序号。如果使用两个天线，则对应于第二天线端口的PUCCH的资源索引通过公式(2)计算获取。UE在第一下行载波上检测到第一类下行数据，就通过第一上行载波上的PUCCH资源进行反馈。Specifically, in the third solution, the UE can feed back the detection result in the format of PUCCH format 1a or PUCCH format 1b, and the PUCCH resource used by the UE to feed back the detection result is related to the number of antennas, which corresponds to the PUCCH of the first antenna port. The resource index is calculated and obtained by formula (1).

图5为本发明上行控制信道传输方法实施例五的流程图，如图5所示，本实施例的方法可以包括：FIG. 5 is a flowchart of Embodiment 5 of an uplink control channel transmission method according to the present invention. As shown in FIG. 5 , the method of this embodiment may include:

步骤501、在第一下行载波上检测到第二类下行数据；Step 501, detecting the second type of downlink data on the first downlink carrier;

本实施例的执行主体为UE。UE在第一下行载波上检测到第二类下行数据，即没有PDCCH调度的PDSCH，通常来讲这一类PDSCH为下行SPS调度方式发送的下行数据，网络设备只在激活下行SPS时发送PDCCH，直到释放下行SPS时再次发送PDCCH，在这期间PDSCH使用的资源都是由最近的一次激活下行SPS时发送的PDCCH来调度的，资源相对固定。The execution subject of this embodiment is the UE. The UE detects the second type of downlink data on the first downlink carrier, that is, the PDSCH without PDCCH scheduling. Generally speaking, this type of PDSCH is the downlink data sent by the downlink SPS scheduling method. The network device only sends the PDCCH when the downlink SPS is activated. , until the PDCCH is sent again when the downlink SPS is released. During this period, the resources used by the PDSCH are scheduled by the PDCCH sent when the downlink SPS is activated most recently, and the resources are relatively fixed.

步骤502、根据第一下行载波以及第二类下行数据，采用第四方案确定发送HARQ-ACK反馈信息的PUCCH的格式、PUCCH的资源索引。Step 502: According to the first downlink carrier and the second type of downlink data, adopt the fourth scheme to determine the format of the PUCCH and the resource index of the PUCCH for sending the HARQ-ACK feedback information.

本实施例中，UE检测到的是第二类下行数据，采用第四方案确定发送 HARQ-ACK反馈信息的PUCCH的格式、PUCCH的资源索引，第四方案包括：In this embodiment, what the UE detects is the second type of downlink data, and the fourth scheme is used to determine the format of the PUCCH and the resource index of the PUCCH for sending the HARQ-ACK feedback information. The fourth scheme includes:

确定发送所述HARQ-ACK反馈信息的所述PUCCH的格式为所述第三格式或所述第二格式；根据网络设备配置的在所述第一上行载波或所述第二上行载波上的至少一个可用于反馈所述第二类下行数据的检测结果的所述 PUCCH资源和最近的一个指示所述下行SPS激活的PDCCH中的所述TPC 命令字段的信息确定对应于第一天线端口的所述第一上行载波或所述第二上行载波的所述PUCCH的资源索引

和对应于第二天线端口的所述第一上行载波或所述第二上行载波的所述PUCCH的资源索引It is determined that the format of the PUCCH for sending the HARQ-ACK feedback information is the third format or the second format; according to at least the first uplink carrier or the second uplink carrier configured by the network device. A PUCCH resource that can be used to feed back the detection result of the second type of downlink data and the latest information of the TPC command field in the PDCCH indicating the activation of the downlink SPS determine the PUCCH corresponding to the first antenna port. Resource index of the PUCCH of the first uplink carrier or the second uplink carrier

and the resource index of the PUCCH corresponding to the first uplink carrier or the second uplink carrier of the second antenna port

具体来讲，第四方案中，UE可以通过PUCCH format 1a或PUCCH format 1b的格式来反馈检测结果，并且UE反馈检测结果所使用的PUCCH 资源同样和天线数相关，UE根据最近的一次网络设备激活下行SPS时发送的PDCCH中的TPC命令字段的信息结合网络设备配置的在第一上行载波上可用于反馈第二类下行数据的检测结果的PUCCH资源，最终确定对应于第一天线端口和第二天线端口的PUCCH的资源索引。UE在第一下行载波上检测到第二类下行数据，就通过第一上行载波上的PUCCH资源进行反馈。Specifically, in the fourth solution, the UE can feed back the detection result in the format of PUCCH format 1a or PUCCH format 1b, and the PUCCH resource used by the UE to feed back the detection result is also related to the number of antennas. The information of the TPC command field in the PDCCH sent during downlink SPS is combined with the PUCCH resources configured by the network device on the first uplink carrier that can be used to feed back the detection results of the second type of downlink data, and finally determine the corresponding first antenna port and the second type of downlink data. Resource index of the PUCCH of the antenna port. When the UE detects the second type of downlink data on the first downlink carrier, it feeds back through the PUCCH resources on the first uplink carrier.

进一步的，UE在所述第二下行载波上检测到网络设备发送了所述第二类下行数据；根据所述第二下行载波以及所述第二类下行数据，采用第四方案确定发送HARQ-ACK反馈信息的所述PUCCH的格式、PUCCH的资源索引。Further, the UE detects on the second downlink carrier that the network device has sent the second type of downlink data; according to the second downlink carrier and the second type of downlink data, the fourth scheme is used to determine to send the HARQ- The format of the PUCCH and the resource index of the PUCCH of the ACK feedback information.

上述图4和图5所示的实施例，UE在哪个下行载波上检测到下行数据，就通过相应的方案在该下行载波对应的上行载波上确定发送HARQ-ACK反馈信息的PUCCH的格式和资源索引，即UE在第一下行载波检测到下行数据就在第一上行载波上反馈，UE在第二下行载波上检测到下行数据就在第二上行载波上反馈，根据下行数据的类型不同，计算PUCCH的资源索引的方案不同，这样一来UE不必集中在一个上行载波上进行反馈，而是进行了负载均衡，解决现有技术中UE只在PCell的PUCCH上反馈HARQ-ACK信息导致PCell的上行载波负载过重的问题，提高传输性能。In the above-mentioned embodiments shown in Figures 4 and 5, on which downlink carrier the UE detects downlink data, it determines the format and resources of the PUCCH for sending the HARQ-ACK feedback information on the uplink carrier corresponding to the downlink carrier through a corresponding scheme. Index, that is, when the UE detects downlink data on the first downlink carrier, it feeds back on the first uplink carrier, and when the UE detects downlink data on the second downlink carrier, it feeds back on the second uplink carrier. According to the type of downlink data, The scheme for calculating the resource index of the PUCCH is different. In this way, the UE does not have to concentrate on one uplink carrier for feedback, but performs load balancing, which solves the problem that the UE only feeds back the HARQ-ACK information on the PUCCH of the PCell in the prior art, which causes the PCell to fail. The problem of the overload of the uplink carrier is too heavy, and the transmission performance is improved.

进一步的，上述图4和图5所示的实施例是UE只在第一下行载波或第二下行载波上检测到下行数据，同样的，该方法适用于UE在第一下行载波和第二下行载波上同时检测到下行数据，UE根据检测到的下行数据的类型在下行载波对应的上行载波上进行反馈。Further, the above-mentioned embodiments shown in FIG. 4 and FIG. 5 are that the UE detects downlink data only on the first downlink carrier or the second downlink carrier. Similarly, this method is applicable to the UE on the first downlink carrier and the second downlink carrier. Downlink data is detected on the two downlink carriers at the same time, and the UE performs feedback on the uplink carrier corresponding to the downlink carrier according to the type of the detected downlink data.

进一步的，在上述图1～图5所示的方法实施例中，UE确定了发送 HARQ-ACK反馈信息的PUCCH的格式、PUCCH的资源索引之后，还需要 UE确定PUCCH的功控信息，实现方法可以是：若确定在所述第一上行载波上发送所述HARQ-ACK反馈信息，则根据所述第一下行载波上的所述 PDCCH中的所述TPC命令字段的信息获取所述PUCCH的功控信息；若确定在所述第二上行载波上发送所述HARQ-ACK反馈信息，则根据所述第二下行载波上的所述PDCCH中的所述TPC命令字段的信息获取所述PUCCH 的功控信息。Further, in the method embodiments shown in FIG. 1 to FIG. 5 above, after the UE determines the format of the PUCCH and the resource index of the PUCCH for sending the HARQ-ACK feedback information, the UE also needs to determine the power control information of the PUCCH. It may be: if it is determined that the HARQ-ACK feedback information is sent on the first uplink carrier, obtain the information of the PUCCH according to the information in the TPC command field in the PDCCH on the first downlink carrier. power control information; if it is determined to send the HARQ-ACK feedback information on the second uplink carrier, obtain the PUCCH according to the information in the TPC command field in the PDCCH on the second downlink carrier Power control information.

具体来讲，UE在确定了发送HARQ-ACK反馈信息的PUCCH的格式和资源索引之后，还需要对该PUCCH进行功控，以确保网络设备能接收到该 PUCCH并正确解码，UE进行功控的依据来自于检测到的下行数据的 PDCCH中的TPC命令字段的信息，如果是第一类下行数据，则该PDCCH 为调度PDSCH的PDCCH，或者为网络设备释放下行SPS发送的PDCCH，如果是第二类下行数据，则该PDCCH为最近的一个网络设备指示下行SPS 激活的PDCCH。UE确定在哪个上行载波上发送HARQ-ACK反馈信息，就根据与该上行载波对应的下行载波上发送的PDCCH中的TPC命令字段的信息。Specifically, after the UE determines the format and resource index of the PUCCH for sending the HARQ-ACK feedback information, it also needs to perform power control on the PUCCH to ensure that the network device can receive the PUCCH and decode it correctly, and the UE performs power control. According to the information from the TPC command field in the PDCCH of the detected downlink data, if it is the first type of downlink data, the PDCCH is the PDCCH that schedules the PDSCH, or the PDCCH sent by the network device to release the downlink SPS. If the downlink data is similar, the PDCCH is the PDCCH that the nearest network device indicates the downlink SPS activation. The UE determines on which uplink carrier to send the HARQ-ACK feedback information according to the information in the TPC command field in the PDCCH sent on the downlink carrier corresponding to the uplink carrier.

这样，eNodeB在下行载波为UE发送下行数据后，无论UE在各载波上对数据的检测结果如何，无论UE采用第几方案确定反馈HARQ-ACK的 PUCCH信道的格式是PUCCH format3、PUCCH format 1a或者PUCCH format 1b，eNodeB都在下行载波上用相同的TPC命令字控制对应小区的上行载波PUCCH的发射功率，解决了PUCCH功率控制错误的问题。In this way, after the eNodeB sends downlink data to the UE on the downlink carrier, no matter what the UE detects on each carrier, no matter what scheme the UE adopts to determine that the format of the PUCCH channel for feeding back HARQ-ACK is PUCCH format 3, PUCCH format 1a or In PUCCH format 1b, the eNodeB uses the same TPC command word on the downlink carrier to control the transmit power of the uplink carrier PUCCH of the corresponding cell, which solves the problem of PUCCH power control errors.

图6为本发明上行控制信道传输方法实施例六的流程图，如图6所示，本实施例的方法可以包括：FIG. 6 is a flowchart of Embodiment 6 of an uplink control channel transmission method according to the present invention. As shown in FIG. 6 , the method of this embodiment may include:

步骤601、为用户设备UE配置发送混合自动重传请求HARQ-ACK反馈信息的物理上行控制信道PUCCH的第一上行载波和第二上行载波；Step 601: Configure the first uplink carrier and the second uplink carrier of the physical uplink control channel PUCCH for sending the hybrid automatic repeat request HARQ-ACK feedback information for the user equipment UE;

本实施例的执行主体为网络设备。网络设备需要为UE配置哪个是第一上行载波，哪个是第二上行载波，以及第一上行载波对应的第一小区和第二上行载波对应的第二小区，在后续的操作中网络设备和UE就可以准确的获取到发送HARQ-ACK反馈信息的PUCCH资源。The execution subject of this embodiment is a network device. The network device needs to configure for the UE which is the first uplink carrier, which is the second uplink carrier, and the first cell corresponding to the first uplink carrier and the second cell corresponding to the second uplink carrier. In subsequent operations, the network device and the UE The PUCCH resource for sending the HARQ-ACK feedback information can be accurately obtained.

本实施例中，所述下行载波包括属于第一小区的第一下行载波和/或属于第二小区的第二下行载波和/或至少一个属于其它小区的下行载波，所述下行数据为第一类下行数据或者第二类下行数据，所述第一类下行数据为由物理下行控制信道PDCCH调度的物理下行共享数据信道PDSCH或者释放下行半静态调度SPS的PDCCH，所述第二类下行数据为没有PDCCH调度的 PDSCH。网络设备向UE发送下行数据，下行载波包括第一小区的第一下行载波，第二小区的第二下行载波，其它小区的下行载波，网络设备发送的下行数据分为两类，一类是有PDCCH调度的PDSCH或释放下行SPS的 PDCCH，前者可以认为是动态调度状态下，每次网络设备发送下行数据都会在在下行载波的PDCCH上携带上PDSCH的资源信息，后者网络设备在激活下行SPS时向UE发送一个PDCCH，告知UE在后续的一段时间内网络设备会根据固定的资源发送PDSCH，然后网络设备在释放下行SPS时再向UE 发送一个PDCCH，告知UE下行SPS调度方式结束；另一类是没有PDCCH 调度的PDSCH，可以认为这一类数据即下行SPS调度，网络设备在激活下行SPS时已经预先分配了PDSCH的资源，因此在后续一段时间内，网络设备将会使用相同的资源发送下行数据。网络设备在发送下行数据后需要确定 UE针对下行数据反馈HARQ-ACK信息的PUCCH资源，例如，网络设备在第一下行载波和第二下行载波上都向UE发送了下行数据，UE具体在哪个上行载波上发送HARQ-ACK反馈信息网络设备是不知道的，因此网络设备认为UE在第一上行载波和第二上行载波上都有可能会发送HARQ-ACK反馈信息，因此网络设备确定的PUCCH资源即包括第一上行载波和第二上行载波。In this embodiment, the downlink carrier includes a first downlink carrier belonging to a first cell and/or a second downlink carrier belonging to a second cell and/or at least one downlink carrier belonging to other cells, and the downlink data is the first downlink carrier One type of downlink data or the second type of downlink data, the first type of downlink data is the physical downlink shared data channel PDSCH scheduled by the physical downlink control channel PDCCH or the PDCCH that releases the downlink semi-persistently scheduled SPS, the second type of downlink data For PDSCH without PDCCH scheduling. The network equipment sends downlink data to the UE. The downlink carriers include the first downlink carrier of the first cell, the second downlink carrier of the second cell, and the downlink carriers of other cells. The downlink data sent by the network equipment is divided into two categories, one is There is a PDSCH scheduled by PDCCH or a PDCCH that releases downlink SPS. The former can be considered as a dynamic scheduling state. Every time the network device sends downlink data, it will carry the PDSCH resource information on the PDCCH of the downlink carrier. The latter network device is activating the downlink. During SPS, a PDCCH is sent to the UE to inform the UE that the network device will send the PDSCH according to fixed resources in the following period of time, and then the network device sends another PDCCH to the UE when the downlink SPS is released to inform the UE that the downlink SPS scheduling mode is over; One is the PDSCH without PDCCH scheduling. It can be considered that this type of data is the downlink SPS scheduling. The network device has pre-allocated PDSCH resources when activating the downlink SPS. Therefore, the network device will use the same resources in the following period of time. Send downstream data. After the network device sends the downlink data, it needs to determine the PUCCH resource for the UE to feed back HARQ-ACK information for the downlink data. For example, the network device sends the downlink data to the UE on both the first downlink carrier and the second downlink carrier. The network equipment does not know the HARQ-ACK feedback information sent on the uplink carrier, so the network equipment believes that the UE may send HARQ-ACK feedback information on both the first uplink carrier and the second uplink carrier. Therefore, the PUCCH resource determined by the network equipment That is, it includes the first uplink carrier and the second uplink carrier.

步骤603、根据确定的所述PUCCH资源检测所述UE在上行载波上发送的所述HARQ-ACK反馈信息。Step 603: Detect the HARQ-ACK feedback information sent by the UE on the uplink carrier according to the determined PUCCH resource.

本实施例中，所述上行载波包括属于所述第一小区的第一上行载波和/ 或属于所述第二小区的第二上行载波。网络设备根据确定的UE可能会发送 HARQ-ACK反馈信息的PUCCH资源，检测UE发送的HARQ-ACK反馈信息，具体来讲，网络设备会在确定的PUCCH资源上逐个检测，这里的 PUCCH资源至少有一个，只要UE在任何一载波上检测到两种类型数据中的任何一种下行数据，都会在其中的某一个PUCCH资源上进行反馈，网络设备负责将该反馈信息检测出来并解析以确定下一步的操作。这里网络设备配置的UE可用于发送HARQ-ACK反馈信息的上行载波包括第一上行载波和第二上行载波。In this embodiment, the uplink carrier includes a first uplink carrier belonging to the first cell and/or a second uplink carrier belonging to the second cell. The network device detects the HARQ-ACK feedback information sent by the UE according to the determined PUCCH resources that the UE may send the HARQ-ACK feedback information. Specifically, the network device will detect the determined PUCCH resources one by one. One, as long as the UE detects any downlink data of the two types of data on any carrier, it will feedback on one of the PUCCH resources, and the network device is responsible for detecting and parsing the feedback information to determine the next step operation. Here, the UE configured by the network device and the uplink carrier that can be used for sending the HARQ-ACK feedback information includes the first uplink carrier and the second uplink carrier.

本实施例，通过网络设备在下行载波上向UE发送下行数据，并配置UE 可以通过第一上行载波和/或第二上行载波上发送HARQ-ACK反馈信息，以对多个小区的下行数据进行反馈，减轻上行载波的负载，解决现有技术中 UE只在PCell的PUCCH上反馈HARQ-ACK信息导致PCell的上行载波负载过重的问题，提高通信性能。In this embodiment, the network device sends downlink data to the UE on the downlink carrier, and configures the UE to send HARQ-ACK feedback information on the first uplink carrier and/or the second uplink carrier, so as to perform downlink data processing on the downlink data of multiple cells. feedback, reduce the load of the uplink carrier, solve the problem that the UE only feeds back HARQ-ACK information on the PUCCH of the PCell and cause the overload of the uplink carrier of the PCell in the prior art, and improve the communication performance.

进一步的，在上述方法实施例的步骤601之前，还包括预先为所述UE 配置发送所述HARQ-ACK反馈信息的所述PUCCH的格式为PUCCH格式 format 3以及所述UE发送所述PUCCH format 3的信道资源。具体来讲，网络设备在开始下行调度之前，预先配置UE是按照PUCCH format 3的格式来进行HARQ-ACK反馈的，并且预先为UE分配了发送PUCCH format 3的信道资源，这是一个预配置的过程，在后续的具体下行数据发送过程中，UE 可能会根据下行数据中的PDCCH再具体调整发送PUCCH的资源。Further, beforestep 601 in the above method embodiment, the method further includes preconfiguring the UE to send the HARQ-ACK feedback information in a format of the PUCCH as PUCCH format format 3 and the UE sending the PUCCH format 3 channel resources. Specifically, before starting downlink scheduling, the network device pre-configures the UE to perform HARQ-ACK feedback in the format of PUCCH format 3, and pre-allocates the UE with channel resources for sending PUCCH format 3, which is a pre-configured process, in the subsequent specific downlink data transmission process, the UE may further specifically adjust the resources for transmitting PUCCH according to the PDCCH in the downlink data.

进一步的，上述方法实施例的步骤601通过下行载波向用户设备UE发送下行数据，确定所述UE可用于发送混合自动重传请求HARQ-ACK反馈信息的物理上行控制信道PUCCH资源，具体的实现方法可以是：通过N₁个所述下行载波向所述UE发送所述下行数据，然后假设所述UE在N₂个所述下行载波上检测到了所述下行数据，确定出N₃种所述UE可用于发送所述HARQ-ACK反馈信息的所述PUCCH资源，所述N₁、N₂和N₃为自然数，且

方法可以是：根据所述确定出N₃种所述UE可用于发送所述HARQ-ACK反馈信息的所述PUCCH资源检测所述UE在上行载波上发送的所述 HARQ-ACK反馈信息。Further, step 601 of the above method embodiment sends downlink data to the user equipment UE through the downlink carrier, and determines the physical uplink control channel PUCCH resource that the UE can use to send the HARQ-ACK feedback information of the hybrid automatic repeat request. The specific implementation method is: It may be: sending the downlink data to the UE through the N₁ downlink carriers, and then assuming that the UE detects the downlink data on the N₂ downlink carriers, determine N₃ types of the UE the PUCCH resources available for transmitting the HARQ-ACK feedback information, the N₁ , N₂ and N₃ are natural numbers, and

The method may be: detecting the HARQ-ACK feedback information sent by the UE on the uplink carrier according to the determined N₃ PUCCH resources that the UE can use to send the HARQ-ACK feedback information.

具体来讲，网络设备可以通过N₁个下行载波向UE发送下行数据，这里的N₁个下行载波包括第一下行载波、第二下行载波、其它小区的下行载波，并且每种下行载波的个数不定，可以为0，也可以是大于0的自然数，此处不做具体限定。然后网络设备假设UE实际在N₂个下行载波上检测到了下行数据，例如，网络设备在第一下行载波和第二下行载波上同时向UE发送了下行数据，可以假设UE只在第一下行载波上检测到下行数据，也可以假设 UE在两个下行载波上都检测到下行数据，这是由于数据在传输过程中可能会出现数据丢失、或信号太弱导致UE检测不到数据的情况，而这些是网络设备无法获知的，因此网络设备要假设出各种检测结果，再根据假设的情况确定出N₃种UE可用于发送HARQ-ACK反馈信息的所述PUCCH资源，这里

的是，网络设备假设UE在N₂个下行载波上检测到下行数据，从而确定出 N₃种PUCCH资源，网络设备在检测的时候不一定每个PUCCH资源都需要检测，可能出现网络设备在第一个PUCCH资源中就检测到了HARQ-ACK反馈信息，则不需要再继续检测，这里对于网络设备如果具体检测HARQ-ACK 反馈信息的过程不做具体限定。Specifically, the network device may send downlink data to the UE through N1 downlink carriers, where the N1 downlink carriers include the_first downlink carrier, the second downlink carrier, and downlink carriers_of other cells, and the The number is not fixed, it may be 0, or it may be a natural number greater than 0, which is not specifically limited here. Then the network device assumes that the UE actually detects downlink data on the N₂ downlink carriers. For example, the network device sends downlink data to the UE on the first downlink carrier and the second downlink carrier at the same time. It can be assumed that the UE only detects the downlink data on the first downlink carrier. If downlink data is detected on the uplink carrier, it can also be assumed that the UE detects downlink data on both downlink carriers. This is because the data may be lost during data transmission, or the signal may be too weak to cause the UE to not detect the data. , and these are not known by the network device, so the network device should assume various detection results, and then determine N₃ kinds of the PUCCH resources that the UE can use to send the HARQ-ACK feedback information according to the assumed situation, here

However, the network device assumes that the UE detects downlink data on N₂ downlink carriers, thereby determining N₃ types of PUCCH resources. The network device does not necessarily need to detect every PUCCH resource during detection. If the HARQ-ACK feedback information is detected in one PUCCH resource, there is no need to continue the detection. Here, there is no specific limitation on the process for the network device to specifically detect the HARQ-ACK feedback information.

下面采用几个具体的实施例，对图6所示方法实施例的技术方案进行详细说明。The technical solutions of the method embodiment shown in FIG. 6 are described in detail below by using several specific embodiments.

图7为本发明上行控制信道传输方法实施例七的流程图，如图7所示，本实施例的方法可以包括：FIG. 7 is a flowchart of Embodiment 7 of an uplink control channel transmission method according to the present invention. As shown in FIG. 7 , the method of this embodiment may include:

步骤701、预先为UE配置发送HARQ-ACK反馈信息的PUCCH的格式为PUCCH format 3以及UE发送PUCCH format 3的信道资源；Step 701: Pre-configure the format of the PUCCH for sending the HARQ-ACK feedback information for the UE to be PUCCH format 3 and the channel resources for the UE to send the PUCCH format 3;

本实施例的执行主体为网络设备。网络设备在开始下行调度之前，预先为UE配置了发送PUCCH format 3的信道资源。需要好说明的是，这是一个预配置的过程，在后续的具体下行数据发送过程中，UE可能会根据下行数据中的PDCCH再具体调整发送PUCCH的格式。The execution subject of this embodiment is a network device. Before starting downlink scheduling, the network device pre-configures the UE with channel resources for sending PUCCH format 3. It should be noted that this is a pre-configuration process, and in the subsequent specific downlink data transmission process, the UE may further specifically adjust the format for transmitting the PUCCH according to the PDCCH in the downlink data.

步骤702、为UE配置发送HARQ-ACK反馈信息的PUCCH的第一上行载波和第二上行载波；Step 702: Configure the first uplink carrier and the second uplink carrier of the PUCCH for sending the HARQ-ACK feedback information for the UE;

本实施例中，网络设备为UE配置发送PUCCH所使用的哪个是第一上行载波，哪个是第二上行载波，以及第一上行载波对应的第一小区和第二上行载波对应的第二小区，在后续的操作中网络设备和UE就可以准确的获取到发送HARQ-ACK反馈信息的PUCCH资源。In this embodiment, the network device configures for the UE which is the first uplink carrier and which is the second uplink carrier used for sending the PUCCH, as well as the first cell corresponding to the first uplink carrier and the second cell corresponding to the second uplink carrier, In subsequent operations, the network device and the UE can accurately obtain the PUCCH resource for sending the HARQ-ACK feedback information.

步骤703、在至少一个属于其它小区的下行载波上向UE发送下行数据，同时在至少一个属于其它小区的下行载波上的下行数据的PDCCH中的TPC 命令字段的信息中携带UE发送HARQ-ACK反馈信息的PUCCH format 3的资源索引；Step 703: Send downlink data to the UE on at least one downlink carrier belonging to other cells, and at the same time send the HARQ-ACK feedback to the UE in the information of the TPC command field in the PDCCH of the downlink data on at least one downlink carrier belonging to other cells. The resource index of the PUCCH format 3 of the information;

本实施例中，网络设备在至少一个属于其它小区的下行载波上向UE发送下行数据，其它小区是除第一小区和第二小区之外的小区，网络设备在其它小区上向UE发送下行数据，在这种情况下，按照网络设备和UE预先约定的反馈方案，UE是通过PUCCH format 3进行HARQ-ACK反馈的，因此网络设备在该下行数据的PDCCH中的TPC命令字段的信息中携带UE发送 HARQ-ACK反馈信息的PUCCH format 3的资源索引，该资源索引是第一上行载波或第二上行载波上的资源索引，即网络设备在其它小区向UE发送了下行数据，理想状况下，UE检测到了该下行数据，仍然通过第一上行载波或第二上行载波发送HARQ-ACK反馈信息。需要说明的是，本实施例网络设备在至少一个属于其它小区的下行载波上向UE发送下行数据，除此之外，网络设备还有可能在第一下行载波和/或第二下行载波上向UE发送下行数据，这里不做具体限定。In this embodiment, the network device sends downlink data to the UE on at least one downlink carrier belonging to another cell, the other cells are cells other than the first cell and the second cell, and the network device sends downlink data to the UE on other cells In this case, according to the feedback scheme pre-agreed by the network equipment and the UE, the UE performs HARQ-ACK feedback through PUCCH format 3, so the network equipment carries the UE in the information of the TPC command field in the PDCCH of the downlink data. The resource index of PUCCH format 3 for sending HARQ-ACK feedback information, the resource index is the resource index on the first uplink carrier or the second uplink carrier, that is, the network device sends downlink data to the UE in other cells. Ideally, the UE After the downlink data is detected, the HARQ-ACK feedback information is still sent through the first uplink carrier or the second uplink carrier. It should be noted that the network device in this embodiment sends downlink data to the UE on at least one downlink carrier belonging to another cell. In addition, the network device may also send downlink data on the first downlink carrier and/or the second downlink carrier Send downlink data to the UE, which is not specifically limited here.

步骤704、假设UE在所述至少一个属于其它小区的下行载波上检测到下行数据，则采用第一方案确定UE通过PUCCH format 3在第一上行载波或第二上行载波上发送HARQ-ACK反馈信息的PUCCH资源；Step 704: Assuming that the UE detects downlink data on the at least one downlink carrier belonging to another cell, the first scheme is adopted to determine that the UE sends the HARQ-ACK feedback information on the first uplink carrier or the second uplink carrier through PUCCH format 3. the PUCCH resource;

本实施例中，网络设备假设UE检测到了其它小区的下行载波上的下行数据，采用第一方案确定UE发送HARQ-ACK反馈信息的PUCCH format 3 资源，第一方案包括：In this embodiment, the network device assumes that the UE has detected downlink data on the downlink carriers of other cells, and adopts the first scheme to determine the PUCCH format 3 resources for the UE to send the HARQ-ACK feedback information. The first scheme includes:

根据在所述至少一个属于其它小区的下行载波上的所述下行数据的 PDCCH中的TPC命令字段的信息确定所述UE发送所述HARQ-ACK反馈信息的所述PUCCH format 3的资源索引。The resource index of the PUCCH format 3 in which the UE sends the HARQ-ACK feedback information is determined according to information in the TPC command field of the PDCCH of the downlink data on the at least one downlink carrier belonging to another cell.

具体来讲，网络设备在至少一个属于其它小区的下行载波上的下行数据中已经携带了PUCCH的资源索引，即该下行数据的PDCCH中的TPC命令字段的信息，网络设备再根据这个TPC命令字段的信息确定UE发送 HARQ-ACK反馈信息的PUCCH资源。Specifically, the network device already carries the resource index of the PUCCH in the downlink data on at least one downlink carrier belonging to another cell, that is, the information of the TPC command field in the PDCCH of the downlink data. The information determines the PUCCH resource for the UE to send the HARQ-ACK feedback information.

步骤705、根据确定的PUCCH资源检测UE在上行载波上发送的 HARQ-ACK反馈信息。Step 705: Detect HARQ-ACK feedback information sent by the UE on the uplink carrier according to the determined PUCCH resource.

本实施例中，网络设备根据在步骤704中确定的PUCCH资源，检测UE 发送的HARQ-ACK反馈信息。In this embodiment, the network device detects the HARQ-ACK feedback information sent by the UE according to the PUCCH resource determined instep 704 .

本实施例，网络设备在其它小区的下行载波上向UE发送了下行数据，并在该下行数据的PDCCH中的TPC命令字段的信息中携带UE发送 HARQ-ACK反馈信息的PUCCH format 3的资源索引，指定UE即将使用第一上行载波或第二上行载波，网络设备再在该PUCCH资源上检测UE的反馈信息。In this embodiment, the network device sends downlink data to the UE on the downlink carrier of another cell, and the information in the TPC command field in the PDCCH of the downlink data carries the resource index of PUCCH format 3 for the UE to send the HARQ-ACK feedback information , specifying that the UE is about to use the first uplink carrier or the second uplink carrier, and the network device then detects the feedback information of the UE on the PUCCH resource.

进一步的，在上述方法实施例的步骤704之后，还包括网络设备在所述第一下行载波上的所述下行数据中的所述PDCCH中的所述TPC命令字段的信息中携带所述UE在所述第一上行载波上发送所述HARQ-ACK反馈信息的所述PUCCH的功控信息；在所述第二下行载波上的所述下行数据中的所述 PDCCH中的所述TPC命令字段的信息中携带所述UE在所述第二上行载波上发送所述HARQ-ACK反馈信息的所述PUCCH的功控信息。具体来讲，网络设备如果在下行载波上发送第一类下行数据，就会在调度PDSCH的 PDCCH或者释放下行SPS的PDCCH中携带功控信息，网络设备如果在下行载波上发送第二类下行数据，就会通过最近的一次指示激活下行SPS的 PDCCH中携带功控信息，特殊情况下，即网络设备没有在第一下行载波或第二下行载波上发送下行数据，但会在这两个下行载波上发送带功控指令的 PDCCH，网络设备将功控信息通过PDCCH指示给UE，UE在哪个对应的上行载波上发HARQ-ACK反馈信息就用哪个下行载波上的PDCCH的TPC命令字段的信息获取PUCCH的功控信息。需要说明的，无论网络设备如何向 UE发送下行数据，都是通过上述方法向UE指示功控信息的，此处不做具体限定。由此解决了可能的PUCCH功率控制错误的问题Further, afterstep 704 in the above method embodiment, the method further includes that the network device carries the UE in the information of the TPC command field in the PDCCH in the downlink data on the first downlink carrier Send the power control information of the PUCCH of the HARQ-ACK feedback information on the first uplink carrier; the TPC command field in the PDCCH in the downlink data on the second downlink carrier The information carries the power control information of the PUCCH that the UE sends the HARQ-ACK feedback information on the second uplink carrier. Specifically, if the network device sends the first type of downlink data on the downlink carrier, it will carry power control information in the PDCCH that schedules the PDSCH or the PDCCH that releases the downlink SPS. If the network device sends the second type of downlink data on the downlink carrier , the power control information will be carried in the PDCCH through the latest instruction to activate the downlink SPS. In special cases, that is, the network device does not send downlink data on the first downlink carrier or the second downlink carrier, but will The PDCCH with power control command is sent on the carrier, and the network device indicates the power control information to the UE through the PDCCH. The UE sends the HARQ-ACK feedback information on the corresponding uplink carrier. The information in the TPC command field of the PDCCH on which downlink carrier is used. Obtain the power control information of the PUCCH. It should be noted that no matter how the network device sends downlink data to the UE, the power control information is indicated to the UE through the above method, which is not specifically limited here. This solves the problem of possible PUCCH power control errors

进一步的，上述方法实施例的步骤703～705还可有另外的情况，网络设备根据假设UE检测到下行数据的情况，采用相应的方案确定UE发送 HARQ-ACK反馈信息的PUCCH资源，具体来讲，有以下几种情况：Further,steps 703 to 705 in the above method embodiment may also have another situation. The network device adopts a corresponding scheme to determine the PUCCH resource for the UE to send the HARQ-ACK feedback information according to the assumption that the UE detects the downlink data. Specifically, , there are the following situations:

第一种、网络设备假设所述UE同时在所述第一下行载波和所述第二下行载波上检测到所述下行数据且没有在属于其它小区的下行载波上检测到所述下行数据，则采用第二方案确定所述UE通过PUCCH format 1b在所述第一上行载波或所述第二上行载波上发送所述HARQ-ACK反馈信息的所述 PUCCH资源，第二方案包括：First, the network device assumes that the UE detects the downlink data on the first downlink carrier and the second downlink carrier at the same time and does not detect the downlink data on the downlink carriers belonging to other cells, Then adopt the second scheme to determine the PUCCH resource for the UE to send the HARQ-ACK feedback information on the first uplink carrier or the second uplink carrier through PUCCH format 1b, and the second scheme includes:

在所述第一小区内，根据所述第一类下行数据中的所述PDCCH确定所述UE用于发送所述HARQ-ACK反馈信息的PUCCH资源，或者，根据为所述UE在所述第一上行载波上配置的至少一个可用于反馈所述第二类下行数据的检测结果的所述PUCCH资源和在最近的一个指示所述下行SPS激活的 PDCCH中的TPC命令字段的信息中配置的所述UE发送所述HARQ-ACK反馈信息的所述PUCCH资源，确定所述UE在第一小区内用于发送 HARQ-ACK反馈信息的PUCCH资源；在所述第二小区内，根据所述第一类下行数据中的所述PDCCH确定所述UE用于发送所述HARQ-ACK反馈信息的PUCCH资源，或者，根据为所述UE在所述第二上行载波上配置的至少一个可用于反馈所述第二类下行数据的检测结果的所述PUCCH资源和在最近的一个指示所述下行SPS激活的PDCCH中的TPC命令字段的信息中配置的所述UE发送所述HARQ-ACK反馈信息的所述PUCCH资源，确定所述UE 在第二小区内用于发送HARQ-ACK反馈信息的PUCCH资源；为所述UE配置信道选择方案，根据所述信道选择方案确定所述UE在所述第一上行载波或所述第二上行载波上发送所述HARQ-ACK反馈信息的所述PUCCH format 1b的资源索引，所述信道选择方案包括预先配置的所述HARQ-ACK反馈信息、上行载波的资源索引、所述HARQ-ACK反馈信息比特之间的对应关系。In the first cell, the PUCCH resource used by the UE to send the HARQ-ACK feedback information is determined according to the PDCCH in the first type of downlink data, or according to At least one of the PUCCH resources configured on an uplink carrier that can be used to feed back the detection result of the second type of downlink data and the information configured in the latest TPC command field in the PDCCH indicating the activation of the downlink SPS. the PUCCH resource used by the UE to send the HARQ-ACK feedback information, and determine the PUCCH resource used by the UE to send the HARQ-ACK feedback information in the first cell; in the second cell, according to the first cell The PDCCH in the downlink-like data determines the PUCCH resource used by the UE to send the HARQ-ACK feedback information, or, according to at least one resource configured for the UE on the second uplink carrier that can be used to feed back the HARQ-ACK feedback information The PUCCH resource of the detection result of the second type of downlink data and the information configured in the information of the TPC command field in the latest PDCCH indicating the downlink SPS activation, the UE sending the HARQ-ACK feedback information PUCCH resources, determine the PUCCH resources used by the UE to send HARQ-ACK feedback information in the second cell; configure a channel selection scheme for the UE, and determine the UE on the first uplink carrier according to the channel selection scheme Or the resource index of the PUCCH format 1b in which the HARQ-ACK feedback information is sent on the second uplink carrier, and the channel selection scheme includes the pre-configured HARQ-ACK feedback information, the resource index of the uplink carrier, the The corresponding relationship between the HARQ-ACK feedback information bits is described.

这种情况下，网络设备为UE配置信道选择方案，该信道选择方案具体的实现方法见图3所示的方法实施例，对于网络设备来讲，由于不知道UE 的检测结果，而且也不确定UE是从哪个上行载波上反馈信息，但是网络设备可以确定在第一小区和第二小区上配置的传输模式，以及该传输模式支持的TB数，因此对应的网络设备可以计算出每个TB数对应的PUCCH format 1b资源索引，网络设备根据这些第一上行载波或第二上行载波上PUCCHformat 1b资源索引，逐个检测UE的反馈信息。In this case, the network device configures a channel selection scheme for the UE. The specific implementation method of the channel selection scheme is shown in the method embodiment shown in Fig. 3. For the network device, since it does not know the detection result of the UE and is uncertain Which uplink carrier does the UE feed back information from, but the network device can determine the transmission mode configured on the first cell and the second cell, and the number of TBs supported by the transmission mode, so the corresponding network device can calculate the number of TBs for each For the corresponding PUCCH format 1b resource index, the network device detects the feedback information of the UE one by one according to the PUCCH format 1b resource index on the first uplink carrier or the second uplink carrier.

第二种，假设所述UE在所述第一下行载波上检测到所述第一类下行数据，则采用第三方案确定所述UE通过PUCCH format 1a或PUCCH format 1b 在所述第一上行载波上发送所述HARQ-ACK反馈信息的所述PUCCH资源，第三方案包括：In the second type, assuming that the UE detects the first type of downlink data on the first downlink carrier, the third scheme is used to determine that the UE uses PUCCH format 1a or PUCCH format 1b to use the first uplink data The PUCCH resource for sending the HARQ-ACK feedback information on the carrier, the third solution includes:

根据所述下行数据的所述PDCCH使用的资源确定所述UE发送所述 HARQ-ACK反馈信息的所述PUCCH资源；determining the PUCCH resource for the UE to send the HARQ-ACK feedback information according to the resource used by the PDCCH of the downlink data;

为网络设备配置的参数；Calculate and obtain the resource index of the PUCCH corresponding to the first antenna port Wherein, n_CCE is the sequence number of the first control channel element CCE of the PDCCH of the PDSCH scheduled on the first downlink carrier or the second downlink carrier or the sequence number of the PDCCH that releases the downlink SPS. The sequence number of the first CCE,

若网络设备使用两个天线时，根据公式(2)If the network device uses two antennas, according to formula (2)

计算获取对应于第二天线端口的所述PUCCH的资源索引

Calculate and obtain the resource index of the PUCCH corresponding to the second antenna port
