调度方法、设备和系统Scheduling method, device and system

技术领域technical field

本发明涉及通信领域，特别涉及一种调度方法、设备和系统。The present invention relates to the communication field, in particular to a scheduling method, equipment and system.

背景技术Background technique

在无线通信中，基站可以通过HS-SCCH(High Speed Shared Control Channel，高速共享控制信道)和HS-PDSCH(High Speed Physical Downlink Shared Channel，高速物理下行共享信道)对HSDPA(High Speed Downlink Packet Access，高速下行分组接入)用户进行调度，该HSDPA用户中又包括比较特殊的DC HSDPA(Dual-Carrier High Speed Downlink Packet Access，双载波高速下行分组接入)用户。In wireless communication, the base station can communicate with HSDPA (High Speed Downlink Packet Access, High-speed downlink packet access) users are scheduled, and the HSDPA users include relatively special DC HSDPA (Dual-Carrier High Speed Downlink Packet Access, dual-carrier high-speed downlink packet access) users.

针对DC HSDPA用户进行调度时：When scheduling for DC HSDPA users:

DC HSDPA用户接入支持DC HSDPA技术的小区后，可同时接收来自两个异频小区的HS-SCCH的信息和HS-PDSCH的数据，这两个异频小区中的一个为主小区，通过主载波传输数据信号，另一个为辅小区，通过辅载波传输数据信号。同时，DC HSDPA用户通过上行HS-DPCCH(High Speed Dedicated Physical Control Channel，专用物理控制信道)将ACK(Acknowledgement，确认信息)和CQI(Channel Quality Indicator，信道质量指示)信息返馈给基站，完成物理层HARQ(Hybrid Automatic Repeat Request，混合自动重传请求)功能。After DC HSDPA users access a cell that supports DC HSDPA technology, they can simultaneously receive HS-SCCH information and HS-PDSCH data from two different-frequency cells. One of the two different-frequency cells is the primary cell. The carrier transmits data signals, and the other is a secondary cell, which transmits data signals through the secondary carrier. At the same time, DC HSDPA users feed back ACK (Acknowledgment, confirmation information) and CQI (Channel Quality Indicator, channel quality indication) information to the base station through the uplink HS-DPCCH (High Speed Dedicated Physical Control Channel, dedicated physical control channel), completing the physical Layer HARQ (Hybrid Automatic Repeat Request, Hybrid Automatic Repeat Request) function.

支持DC HSDPA技术的UE(User Equipment，用户设备)需要同时监听来自两个异频小区的最多6条HS-SCCH，UE的耗电量较大；此外，在DC HSDPA技术的基础上再引入MIMO(Multiple Input Multiple Output，多入多出)技术后，上行HS-DPCCH会占用较多的上行资源，增加了基站侧的负载。A UE (User Equipment) that supports DC HSDPA technology needs to monitor up to six HS-SCCHs from two different-frequency cells at the same time, and the UE consumes a lot of power; in addition, MIMO is introduced on the basis of DC HSDPA technology (Multiple Input Multiple Output) technology, the uplink HS-DPCCH will occupy more uplink resources, increasing the load on the base station side.

针对上述问题，在UE的数据传输量较低或基站的负载达到最大门限时，可通过HS-SCCH下发去激活指令将UE的状态修改为SC HSDPA(Single-Carrier High Speed Downlink Packet Access，单载波高速下行分组接入)状态，即辅载波去激活，只保留主载波进行数据信号的传输，达到减小UE耗电量和降低基站负载的目的。辅载波去激活后，还可以通过HS-SCCH下发激活指令将UE重新激活为DC HSDPA状态，即辅载波激活，提高UE的速率。In view of the above problems, when the data transmission volume of the UE is low or the load of the base station reaches the maximum threshold, the state of the UE can be changed to SC HSDPA (Single-Carrier High Speed Downlink Packet Access, Single-Carrier High Speed Downlink Packet Access, Single-Carrier High Speed Downlink Packet Access, etc.) Carrier high-speed downlink packet access) state, that is, the auxiliary carrier is deactivated, and only the main carrier is reserved for data signal transmission, so as to reduce UE power consumption and base station load. After the secondary carrier is deactivated, the UE can be reactivated to the DC HSDPA state by sending an activation instruction through the HS-SCCH, that is, the secondary carrier is activated to increase the UE's rate.

针对HSDPA用户进行调度时：When scheduling for HSDPA users:

HSDPA用户支持HS-SCCH less operation(无HS-SCCH伴随)模式，HS-SCCHless operation的基本原理是减少HSDPA低速业务的伴随信道HS-SCCH的发送，即在HS-PDSCH新传数据时不需要伴随HS-SCCH，重传数据时需要伴随HS-SCCH的HS-SCCH新模式。HSDPA users support HS-SCCH less operation (without HS-SCCH accompanying) mode. The basic principle of HS-SCCHless operation is to reduce the transmission of the accompanying channel HS-SCCH for HSDPA low-speed services, that is, no accompanying channel is required when HS-PDSCH transmits data. HS-SCCH, a new HS-SCCH mode accompanied by HS-SCCH is required when retransmitting data.

在无线环境较好、下行发送重传率较低时，在HS-SCCH less operation模式下，由于新传数据时不需要伴随HS-SCCH，基站可以节省HS-SCCH功率，对于弱覆盖区域，由于HS-SCCH信道可能消耗10％以上的小区功率，所以HS-SCCH功率节省下来后可以提升弱覆盖区域的吞吐率，扩大小区覆盖范围；同时，减少HS-SCCH的发送可以节省HS-SCCH码字资源，从而下行能够在一个TTI(Transmission Time Interval，传输时间间隔)内调度更多的UE，提高下行容量；不过，由于下行调度的UE数增加，上行HS-DPCCH反馈变多，所以上行负载会稍有增加；对UE来说，使用HS-SCCH less operation模式后，UE需要对HS-PDSCH信道进行盲检测，因此需要消耗比原来更多的功率，耗电量大。When the wireless environment is good and the downlink transmission retransmission rate is low, in the HS-SCCH less operation mode, the base station can save HS-SCCH power because the newly transmitted data does not need to be accompanied by the HS-SCCH. The HS-SCCH channel may consume more than 10% of the cell power, so after saving the HS-SCCH power, it can improve the throughput rate of the weak coverage area and expand the coverage of the cell; at the same time, reducing the transmission of HS-SCCH can save HS-SCCH codewords Resources, so that the downlink can schedule more UEs within a TTI (Transmission Time Interval, transmission time interval), and improve the downlink capacity; however, due to the increase in the number of UEs scheduled in the downlink, the uplink HS-DPCCH feedback increases, so the uplink load There will be a slight increase; for the UE, after using the HS-SCCH less operation mode, the UE needs to perform blind detection on the HS-PDSCH channel, so it needs to consume more power than before, and the power consumption is large.

目前，可以通过HS-SCCH下发去激活指令将UE的状态修改为非HS-SCCH lessoperation模式，达到减小UE耗电量和降低基站上行负载的目的；同样，也可以通过HS-SCCH下发激活指令将UE的状态重新激活为HS-SCCH less operation模式，达到提升小区容量的目的。At present, the state of the UE can be changed to a non-HS-SCCH lessoperation mode by sending a deactivation command through the HS-SCCH to achieve the purpose of reducing the power consumption of the UE and the uplink load of the base station; similarly, it can also be sent through the HS-SCCH The activation command reactivates the state of the UE to the HS-SCCH less operation mode to achieve the purpose of improving the capacity of the cell.

综上所述，DC HSDPA用户辅载波激活去激活技术和HSDPA用户HS-SCCH lessoperation激活去激活技术均可以在不增加空口信令开销的情况下快速灵活的实现UE状态修改。To sum up, both DC HSDPA user secondary carrier activation and deactivation technology and HSDPA user HS-SCCH lessoperation activation and deactivation technology can quickly and flexibly realize UE state modification without increasing air interface signaling overhead.

在实现本发明的过程中，发明人发现现有技术至少存在以下缺点：In the process of realizing the present invention, the inventor finds that the prior art has at least the following disadvantages:

无论是DC HSDPA用户辅载波激活去激活技术，还是HSDPA用户HS-SCCH lessoperation激活去激活技术，当基站通过HS-SCCH发送激活或去激活的指令后，UE的状态不会立即改变。从基站发送指令到UE状态改变的这段时间间隔内，基站侧和UE侧的行为可能不一致，此种情况下，容易出现丢失数据帧的情况，进而使基站侧的行为与UE的状态出现更长时间的不一致，导致系统性能损失。Regardless of the DC HSDPA secondary carrier activation and deactivation technology, or the HSDPA user HS-SCCH lessoperation activation and deactivation technology, when the base station sends an activation or deactivation instruction through the HS-SCCH, the state of the UE will not change immediately. During the time interval from when the base station sends an instruction to when the UE state changes, the behaviors of the base station side and the UE side may be inconsistent. Long-term inconsistency, resulting in loss of system performance.

为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施方式作进一步地详细描述。In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

实施例一Embodiment one

本发明实施例提供了一种调度方法，参见图1，方法流程具体如下：The embodiment of the present invention provides a scheduling method, see Figure 1, the method flow is as follows:

101：向HSDPA UE发送状态指令，该状态指令包括激活指令或去激活指令；101: Send a status command to the HSDPA UE, where the status command includes an activation command or a deactivation command;

102：判断该UE的状态是否改变；102: Determine whether the state of the UE has changed;

103：在该UE的状态改变之前，按照预设的调度策略进行针对该UE的下行调度。103: Before the state of the UE changes, perform downlink scheduling for the UE according to a preset scheduling policy.

其中，该预设的调度策略保证下行调度行为与该UE的状态相符合。Wherein, the preset scheduling strategy ensures that the downlink scheduling behavior conforms to the state of the UE.

本发明实施例提供的方法，通过从发送状态指令到UE的状态改变之前的时间间隔内，按照预设的调度策略进行针对该UE的下行调度，明确了基站通过HS-SCCH发送激活或去激活的指令后调度设备侧和UE侧的行为，使调度设备的下行调度行为与UE的状态相符合，提高了系统的性能。In the method provided by the embodiment of the present invention, the downlink scheduling for the UE is performed according to the preset scheduling strategy within the time interval from sending the status command to before the UE status changes, and it is clarified that the base station sends activation or deactivation through the HS-SCCH The behaviors of the scheduling device side and the UE side after the instruction are made, so that the downlink scheduling behavior of the scheduling device is consistent with the state of the UE, and the performance of the system is improved.

实施例二Embodiment two

本发明实施例提供了一种调度方法，该方法除了适用于WCDMA(Wideband Code Division Multiple Access，宽带码分多址)和TDSCDMA(Time Division-Synchronous Code Division Multiple Access，时分同步的码分多址技术)系统之外，还可以应用于其他通信系统。本发明实施例仅以WCDMA中的基站按照R9版本协议调度DC HSDPA用户为例进行说明，但不限定于此。The embodiment of the present invention provides a kind of dispatching method, and this method is applicable to WCDMA (Wideband Code Division Multiple Access, broadband code division multiple access) and TDSCDMA (Time Division-Synchronous Code Division Multiple Access, time division synchronous code division multiple access technology ) system, it can also be applied to other communication systems. The embodiment of the present invention is only described by taking the base station in WCDMA to schedule DC HSDPA users according to the R9 protocol as an example, but is not limited thereto.

参见图2，方法流程具体如下：Referring to Figure 2, the method flow is as follows:

201：向DC HSDPA UE发送状态指令，该状态指令包括辅载波激活指令或辅载波去激活指令；201: Send a status command to the DC HSDPA UE, where the status command includes a secondary carrier activation command or a secondary carrier deactivation command;

其中，由于本实施例的应用场景是针对WCDMA的R9版本协议中的DC HSDPA用户，也就是说，当UE为DC HSDPA用户设备时，该状态指令具体包括辅载波激活指令或辅载波去激活指令。Wherein, since the application scenario of this embodiment is aimed at the DC HSDPA user in the R9 protocol of WCDMA, that is to say, when the UE is a DC HSDPA user equipment, the state instruction specifically includes an auxiliary carrier activation instruction or an auxiliary carrier deactivation instruction .

具体地，可以是网络设备，比如基站，通过HS-SCCH向UE发送状态指令，激活或去激活UE的辅载波。在WCDMA系统中，当向UE发送辅载波激活指令时，是要将UE的SC HSDPA状态激活为DC HSDPA状态；当向UE发送辅载波去激活指令时，是要将UE的DC HSDPA状态去激活为SC HSDPA状态。可以理解的是，在一次过程中，状态指令只会是辅载波激活指令或辅载波去激活指令中的一种，且后续的流程大体类似。本发明实施例的描述中，将两者放在一起描述的目的仅仅是为了叙述简便。Specifically, a network device, such as a base station, may send a status instruction to the UE through the HS-SCCH to activate or deactivate the secondary carrier of the UE. In the WCDMA system, when the secondary carrier activation instruction is sent to the UE, the UE's SC HSDPA state is activated to the DC HSDPA state; when the secondary carrier deactivation instruction is sent to the UE, the UE's DC HSDPA state is deactivated It is SC HSDPA status. It can be understood that, in one process, the status instruction is only one of the auxiliary carrier activation instruction or the auxiliary carrier deactivation instruction, and the subsequent processes are generally similar. In the description of the embodiments of the present invention, the purpose of describing the two together is only for the convenience of description.

202：判断该UE的状态是否改变，如果否，则执行步骤203，如果是，则执行步骤204；202: Determine whether the state of the UE has changed, if not, perform step 203, and if yes, perform step 204;

其中，判断该UE的状态是否改变，具体可以为根据是否获取到该UE的确认信息来判断该UE的状态是否改变，如果未获取到该UE的反馈信息(未获取到反馈信息，也就肯定不会获取到确认信息)，或虽然获取到的反馈信息，但该反馈信息不是ACK(Acknowledgement，确认信息)，则判断该UE的状态未改变。Wherein, judging whether the state of the UE has changed may specifically be to judge whether the state of the UE has changed according to whether the confirmation information of the UE is obtained, and if the feedback information of the UE is not obtained (feedback information is not obtained, it is determined will not obtain acknowledgment information), or although the feedback information is obtained, but the feedback information is not ACK (Acknowledgment, confirmation information), it is determined that the state of the UE has not changed.

具体地，针对该步骤，首先可以通过上行HS-DPCCH获取该UE的反馈信息，该反馈信息可能为ACK、NACK(Negative Acknowledgement，否认信息)和DTX(Discontinuous Transmission，非连续发送)中的一种。反馈信息可以存储在与基站通过HS-SCCH发送状态指令的帧所对应的上行帧中。如果未获取到反馈信息，则判断该UE的辅载波状态未改变；如果获取到的反馈信息是NACK或DTX(即不是ACK)，则也判断该UE的辅载波状态未改变；如果获取到反馈信息是ACK，则判断该UE的辅载波状态已经改变。Specifically, for this step, firstly, the feedback information of the UE can be obtained through the uplink HS-DPCCH, and the feedback information may be one of ACK, NACK (Negative Acknowledgment, deny information) and DTX (Discontinuous Transmission, discontinuous transmission) . The feedback information may be stored in the uplink frame corresponding to the frame in which the base station sends the status instruction through the HS-SCCH. If no feedback information is obtained, it is judged that the state of the secondary carrier of the UE has not changed; if the obtained feedback information is NACK or DTX (that is, not ACK), it is also judged that the state of the secondary carrier of the UE has not changed; If the information is ACK, it is judged that the state of the secondary carrier of the UE has changed.

203：如果该UE的状态未改变，在该UE的状态改变之前，按照预设的调度策略进行针对该UE的下行调度，在该UE的状态改变之后，执行步骤204；203: If the state of the UE has not changed, perform downlink scheduling for the UE according to a preset scheduling strategy before the state of the UE changes, and perform step 204 after the state of the UE changes;

其中，如果该UE的状态未改变，则在该UE的状态改变之前，按照预设的调度策略进行针对该UE的下行调度，该预设的调度策略保证在辅载波上的调度行为与该UE的辅载波状态相符合。此处的预设的调度策略具体为：Wherein, if the state of the UE does not change, before the state of the UE changes, the downlink scheduling for the UE is performed according to a preset scheduling strategy, and the preset scheduling strategy ensures that the scheduling behavior on the secondary carrier is consistent with that of the UE. The status of the secondary carrier matches. The preset scheduling strategy here is specifically:

不进行针对该UE的下行调度；或，Do not perform downlink scheduling for the UE; or,

按照向该UE发送状态指令前原有的调度方式进行针对该UE的下行调度；或，Perform downlink scheduling for the UE according to the original scheduling method before sending the status instruction to the UE; or,

只在主载波进行针对该UE的下行调度。The downlink scheduling for the UE is only performed on the primary carrier.

具体地，不进行针对该UE的下行调度，即从向UE发送状态指令到UE的辅载波状态改变的时间间隔内，基站侧不通过主载波和辅载波针向该UE下发任何调度的数据。同时，接收该UE发送的上行帧。Specifically, the downlink scheduling for the UE is not performed, that is, within the time interval from sending the status instruction to the UE to the UE's secondary carrier status change, the base station side does not send any scheduled data to the UE through the primary carrier and the secondary carrier. . At the same time, the uplink frame sent by the UE is received.

按照向该UE发送状态指令前原有的调度方式进行针对该UE的下行调度，即从向UE发送状态指令到UE的辅载波状态改变的时间间隔内，基站侧按照向该UE发送状态指令前原有的调度方式向该UE下发数据。同时，接收该UE发送的上行帧。The downlink scheduling for the UE is performed according to the original scheduling method before sending the status command to the UE, that is, within the time interval from sending the status command to the UE to the change of the secondary carrier status of the UE, the base station side follows the original scheduling method before sending the status command to the UE. The scheduling mode is used to deliver data to the UE. At the same time, the uplink frame sent by the UE is received.

只在主载波进行针对该UE的下行调度，即从向UE发送状态指令到UE的辅载波状态改变的时间间隔内，基站侧只通过主载波调度该UE，向该UE下发数据。同时，接收该UE发送的上行帧。The downlink scheduling for the UE is only performed on the primary carrier, that is, within the time interval from sending the state command to the UE to the UE's secondary carrier status change, the base station only schedules the UE through the primary carrier and delivers data to the UE. At the same time, the uplink frame sent by the UE is received.

在实际应用中，可以选择上述三种预设的调度策略中的任意一种来实施。In practical applications, any one of the above three preset scheduling strategies can be selected for implementation.

进一步地，UE的状态未改变包括两种情况：Further, the status of the UE has not changed includes two situations:

第一种情况是未获取到反馈信息，此种情况下，继续获取反馈信息；The first case is that the feedback information is not obtained, in this case, continue to obtain the feedback information;

第二种情况是获取到了反馈信息但不是ACK，此种情况下，可以重复执行向UE发送状态指令的步骤。The second case is that the feedback information is obtained but not the ACK. In this case, the step of sending the status instruction to the UE may be repeated.

在第二种情况下，当重复执行向UE发送状态指令的步骤的次数超过最大重传次数后，可以按照向该UE发送状态指令前原有的调度方式进行针对该UE的下行调度。其中，本发明实施例不对最大重传次数进行具体限定，可以根据实际情况进行设定，如可以设为4次。In the second case, when the number of repeated executions of the step of sending the status instruction to the UE exceeds the maximum number of retransmissions, downlink scheduling for the UE may be performed according to the original scheduling method before sending the status instruction to the UE. Wherein, the embodiment of the present invention does not specifically limit the maximum number of retransmissions, which can be set according to actual conditions, for example, it can be set to 4 times.

总之，无论未获取到反馈信息或获取到的反馈信息为NACK或DTX，又或者重复执行向UE发送状态指令的过程当中，该UE的状态均未改变，在该UE的状态改变之前，按照预设的调度策略进行针对该UE的下行调度，并在该UE的状态改变之后，执行步骤204。In short, no matter whether the feedback information is not obtained or the obtained feedback information is NACK or DTX, or the process of repeatedly sending the status instruction to the UE is performed, the status of the UE does not change. Before the status of the UE changes, according to the preset The scheduled scheduling policy performs downlink scheduling for the UE, and after the state of the UE changes, step 204 is executed.

204：如果该UE的状态已改变，则按照状态指令指定的状态进行针对该UE的下行调度，流程结束；204: If the state of the UE has changed, perform downlink scheduling for the UE according to the state specified by the state instruction, and the process ends;

具体地，一旦确定UE的状态发生改变，基站则按照状态指令指定的辅载波激活或去激活状态，进行针对该UE的下行调度。比如，如果UE状态改变后的辅载波为激活状态，则通过主载波和辅载波进行针对该UE的下行调度；如果UE状态改变后的辅载波为去激活状态，则通过主载波进行针对该UE的下行调度。Specifically, once it is determined that the state of the UE has changed, the base station performs downlink scheduling for the UE according to the secondary carrier activation or deactivation state specified by the state instruction. For example, if the secondary carrier after the state change of the UE is in the activated state, the downlink scheduling for the UE is performed through the primary carrier and the secondary carrier; if the secondary carrier is in the deactivated state after the UE state is changed, the UE is scheduled through the primary carrier downscheduling.

另一方面，当UE的状态改变后，立即按照改变后的状态进行上行HS-DPCCH帧发送。On the other hand, when the state of the UE changes, the uplink HS-DPCCH frame is sent immediately according to the changed state.

进一步地，针对本发明实施例提供的方法，具体举例说明如下：Further, for the methods provided in the embodiments of the present invention, specific examples are as follows:

每个帧占用的时间为1个TTI，1TTI＝3slot(时隙)。基站完全下发一条状态指令需要1个TTI，状态指令完全下发后的4个TTI后UE返回反馈信息。当针对某一UE发送状态指令后，根据UE的反馈信息是否为ACK判断UE的状态是否改变，按照定时关系分以下两种情况进行处理：The time occupied by each frame is 1 TTI, 1 TTI = 3 slots (time slots). It takes 1 TTI for the base station to fully issue a status command, and the UE returns feedback information after 4 TTIs after the status command is fully delivered. After sending a status command for a certain UE, it is judged whether the status of the UE has changed according to whether the feedback information of the UE is ACK, and the following two cases are processed according to the timing relationship:

第一种情况：反馈信息是ACK，参见图3：The first case: the feedback information is ACK, see Figure 3:

在第1个TTI，通过HS-SCCH向UE发送状态指令；In the first TTI, send a status instruction to the UE through HS-SCCH;

在第1至第5个TTI内未获取到反馈信息，这段时间间隔内UE的状态未改变，根据预设的调度策略进行针对该UE的下行调度；No feedback information is obtained within the 1st to 5th TTI, and the state of the UE does not change during this time interval, and the downlink scheduling for the UE is performed according to the preset scheduling strategy;

在第6个TTI，基站获取到UE的反馈信息，该反馈信息从UE通过上行HS-DPCCH发送的与HS-SCCH的状态指令对应的帧中获取，并判断为ACK；In the sixth TTI, the base station obtains the feedback information of the UE, which is obtained from the frame corresponding to the HS-SCCH status command sent by the UE through the uplink HS-DPCCH, and is judged as ACK;

在第6个TTI，基站开始按照状态指令指定的辅载波状态进行针对该UE的下行调度；In the sixth TTI, the base station starts to perform downlink scheduling for the UE according to the state of the secondary carrier specified by the state instruction;

UE的辅载波状态改变后立即按照改变后的状态进行上行HS-DPCCH帧发送。After the secondary carrier state of the UE is changed, the uplink HS-DPCCH frame is sent immediately according to the changed state.

第二种情况：反馈信息是NACK或DTX，参见图4：The second case: the feedback information is NACK or DTX, see Figure 4:

在第1个TTI，通过HS-SCCH向UE发送状态指令；In the first TTI, send a status instruction to the UE through HS-SCCH;

在第1至第5个TTI内未获取到反馈信息，这段时间间隔内UE的状态未改变，根据预设的调度策略进行针对该UE的下行调度；No feedback information is obtained within the 1st to 5th TTI, and the state of the UE does not change during this time interval, and the downlink scheduling for the UE is performed according to the preset scheduling strategy;

在第6个TTI，基站获取到UE的反馈信息，该反馈信息从UE通过上行HS-DPCCH发送的与HS-SCCH的状态指令对应的帧中获取，并判断为NACK或DTX；In the sixth TTI, the base station obtains the feedback information of the UE, which is obtained from the frame corresponding to the HS-SCCH status command sent by the UE through the uplink HS-DPCCH, and judged as NACK or DTX;

在第7个TTI向UE重传状态指令；Retransmit the status command to the UE at the seventh TTI;

在第6×N+6(N为大于等于1的自然数，N表示重传次数)个TTI基站获取到UE的反馈信息，该反馈信息从UE通过上行HS-DPCCH发送的与HS-SCCH的状态指令对应的帧中获取，对该反馈信息进行判断：At the 6th×N+6 (N is a natural number greater than or equal to 1, and N represents the number of retransmissions) TTI base station obtains the feedback information of the UE, which is sent by the UE through the uplink HS-DPCCH and the state of the HS-SCCH Get it in the frame corresponding to the instruction, and judge the feedback information:

如果判断为ACK，则按第一种情况进行处理，即在第6×N+6(N为大于等于1的自然数，N表示重传次数)个TTI基站开始按照状态指令指定的状态进行针对该UE的下行调度，该UE的状态改变后立即按照改变后的状态通过上行HS-DPCCH进行帧的发送；If it is judged to be ACK, it will be processed according to the first case, that is, at the 6th×N+6 (N is a natural number greater than or equal to 1, and N represents the number of retransmissions) TTI base stations start to target the state according to the state specified by the state instruction. Downlink scheduling of the UE, after the state of the UE changes, the frame is sent through the uplink HS-DPCCH immediately according to the changed state;

如果判断为NACK或DTX，则继续向UE重传状态指令，其中从第1个TTI至收到ACK(即UE的状态改变)或达到最大重传次数期间，都根据预设的调度策略进行针对该UE的下行调度。If it is judged to be NACK or DTX, continue to retransmit the status instruction to the UE. During the period from the first TTI to receiving ACK (that is, the state of the UE changes) or reaching the maximum number of retransmissions, all are targeted according to the preset scheduling strategy. Downlink scheduling of the UE.

当重传的次数超过最大重传次数后，按照向UE发送状态指令前原有的调度方式进行针对该UE的下行调度。When the number of retransmissions exceeds the maximum number of retransmissions, the downlink scheduling for the UE is performed according to the original scheduling method before sending the status instruction to the UE.

本发明实施例提供的方法，通过从发送状态指令到UE的状态改变之前的时间间隔内，按照预设的调度策略进行针对该UE的下行调度，明确了基站通过HS-SCCH发送激活或去激活的指令后调度设备侧和UE侧的行为，使调度设备的下行调度行为与UE的状态相符合，提高了系统的性能，具体如下：In the method provided by the embodiment of the present invention, the downlink scheduling for the UE is performed according to the preset scheduling strategy within the time interval from sending the status command to before the UE status changes, and it is clarified that the base station sends activation or deactivation through the HS-SCCH The behavior of the scheduling device side and the UE side after the instruction is given, so that the downlink scheduling behavior of the scheduling device is consistent with the state of the UE, and the performance of the system is improved. The details are as follows:

当预设的策略为从发送状态指令到UE的状态改变的时间间隔内，不进行针对该UE的下行调度时，简化了系统实现，避免了基站侧调度和UE的辅载波状态可能不一致导致的现数据帧的丢失及丢失后引起的重传；同时，在不进行针对该UE的下行调度的这段时间间隔内，基站可以调度其他UE，保障了基站的下行吞吐率和系统的稳定性。适用于辅载波激活去激活场景。When the preset strategy is to not perform downlink scheduling for the UE within the time interval from sending the status command to the UE status change, it simplifies the system implementation and avoids possible inconsistencies between the base station side scheduling and the secondary carrier status of the UE. The loss of existing data frames and the retransmission caused by the loss; at the same time, the base station can schedule other UEs during the time interval when the downlink scheduling for this UE is not performed, which ensures the downlink throughput of the base station and the stability of the system. Applicable to the scenario of secondary carrier activation and deactivation.

当预设的策略为从发送状态指令到UE的状态改变的时间间隔内，按照向UE发送状态指令前原有的调度方式进行针对该UE的下行调度时，使基站侧在主载波和辅载波上的数据调度和接收与UE的状态始终保持一致；同时，按照向UE发送状态指令前原有的调度方式进行针对该UE的下行调度还降低了基站侧处理的复杂度，在信道条件较好的情况下，UE侧的数据下载感受也不会下降。主要适用于辅载波去激活场景。When the preset strategy is to perform downlink scheduling for the UE according to the original scheduling method before sending the status command to the UE within the time interval from sending the status command to the UE status change, make the base station side on the main carrier and the secondary carrier The data scheduling and reception of the UE are always consistent with the state of the UE; at the same time, the downlink scheduling for the UE is performed according to the original scheduling method before sending the status command to the UE, which also reduces the complexity of the base station side processing. In this case, the experience of data downloading on the UE side will not decrease. It is mainly applicable to the scenario where the secondary carrier is deactivated.

当预设的策略为从发送状态指令到UE的状态改变的时间间隔内，只在主载波进行针对该UE的下行调度时，无论激活或者去激活辅载波，UE通过主载波的上行HS-DPCCH发送的数据信息都不会受影响，即基站侧可以正确解析单载波的ACK信息，也可以兼容解析双载波的主载波的ACK信息，使信息的传送不受基站侧与UE侧状态不一致的影响；同时，解决了在指令下发后到UE响应ACK之前，基站测调度数据的后续处理风险，提升了系统的可靠性。适用于辅载波激活和去激活场景。When the preset policy is within the time interval from sending the state command to the state change of the UE, only the primary carrier performs downlink scheduling for the UE, no matter whether the secondary carrier is activated or deactivated, the UE passes the uplink HS-DPCCH of the primary carrier The data information sent will not be affected, that is, the base station side can correctly analyze the ACK information of the single carrier, and can also compatiblely analyze the ACK information of the main carrier of the dual carrier, so that the transmission of information will not be affected by the inconsistency between the base station side and the UE side ; At the same time, it solves the risk of subsequent processing of the base station's measurement and scheduling data after the instruction is issued and before the UE responds to the ACK, and improves the reliability of the system. Applicable to auxiliary carrier activation and deactivation scenarios.

实施例三Embodiment Three

本发明实施例提供了一种调度方法，该方法除了适用于WCDMA和TDSCDMA系统之外，还可以应用于其他通信系统。本发明实施例仅以WCDMA中的基站按照R7版本协议调度HSDPA用户(包括DC HSDPA用户)为例进行说明，但不限定于此。The embodiment of the present invention provides a scheduling method, which can be applied to other communication systems besides WCDMA and TDSCDMA systems. The embodiment of the present invention is only described by taking the base station in WCDMA to schedule HSDPA users (including DC HSDPA users) according to the R7 protocol as an example, but is not limited thereto.

参见图5，方法流程具体如下：Referring to Figure 5, the method flow is as follows:

501：向HSDPA UE发送状态指令，该状态指令包括HS-SCCH less operation模式激活指令或HS-SCCH less operation模式去激活指令；501: Send a status command to the HSDPA UE, where the status command includes an HS-SCCH less operation mode activation command or an HS-SCCH less operation mode deactivation command;

其中，由于本实施例的应用场景是针对WCDMA的R7版本协议中的HSDPA用户，也就是说，当UE为HSDPA用户设备时，该状态指令具体包括HS-SCCH lessoperation模式激活指令或HS-SCCH less operation模式去激活指令。Wherein, since the application scenario of this embodiment is for the HSDPA user in the R7 protocol of WCDMA, that is to say, when the UE is an HSDPA user equipment, the state instruction specifically includes the HS-SCCH lessoperation mode activation instruction or the HS-SCCH less Operation mode deactivates the command.

具体地，可以是网络设备，比如基站，通过HS-SCCH向UE发送状态指令，激活或去激活UE的HS-SCCH less operation模式。在WCDMA系统中，当向UE发送HS-SCCH less operation模式激活指令时，是要将UE从原有模式激活为HS-SCCH less operation模式；当向UE发送HS-SCCH less operation模式去激活指令时，是要将UE从HS-SCCH less operation模式去激活为原有模式。当UE的状态在HS-SCCH less operation模式下，UE既可以按照HS-SCCH lessoperation方式接收数据，也可以按照原有方式，即非HS-SCCH less operation方式接收数据。但是如果UE的状态在非HS-SCCH less operation模式下，那么UE按照非HS-SCCH less operation方式接收数据。因此，基站对于处于HS-SCCH less operation模式下的UE，采用HS-SCCH less operation方式或原有方式都可以进行调度发送；而对于处于非HS-SCCH less operation模式下的UE，采用原有方式进行调度发送。Specifically, it may be a network device, such as a base station, that sends a status instruction to the UE through the HS-SCCH to activate or deactivate the HS-SCCH less operation mode of the UE. In the WCDMA system, when the HS-SCCH less operation mode activation command is sent to the UE, it is to activate the UE from the original mode to the HS-SCCH less operation mode; when the HS-SCCH less operation mode deactivation command is sent to the UE , is to deactivate the UE from the HS-SCCH less operation mode to the original mode. When the state of the UE is in the HS-SCCH less operation mode, the UE can receive data in the HS-SCCH less operation mode, or in the original mode, that is, in the non-HS-SCCH less operation mode. However, if the state of the UE is in the non-HS-SCCH less operation mode, then the UE receives data in the non-HS-SCCH less operation mode. Therefore, for UEs in HS-SCCH less operation mode, the base station can use the HS-SCCH less operation method or the original method to schedule and send; and for the UE in non-HS-SCCH less operation mode, use the original method Make a scheduled send.

可以理解的是，在一次过程中，状态指令只会是HS-SCCH less operation模式激活指令或HS-SCCH less operation模式去激活指令中的一种，且后续的流程大体类似。本发明实施例的描述中，将两者放在一起描述的目的仅仅是为了叙述简便。It can be understood that, in one process, the status command will only be one of the HS-SCCH less operation mode activation command or the HS-SCCH less operation mode deactivation command, and the subsequent processes are generally similar. In the description of the embodiments of the present invention, the purpose of describing the two together is only for the convenience of description.

502：判断该UE的状态是否改变，如果否，则执行步骤503，如果是，则执行步骤504；502: Determine whether the state of the UE has changed, if not, executestep 503, and if yes, execute step 504;

其中，判断该UE的状态是否改变，具体可以为根据是否获取到该UE的确认信息来判断该UE的状态是否改变，如果未获取到该UE的反馈信息(未获取到反馈信息，也就肯定不会获取到确认信息)，或虽然获取到的反馈信息，但该反馈信息不是ACK(Acknowledgement，确认信息)，则判断该UE的状态未改变。Wherein, judging whether the state of the UE has changed may specifically be to judge whether the state of the UE has changed according to whether the confirmation information of the UE is obtained, and if the feedback information of the UE is not obtained (feedback information is not obtained, it is determined will not obtain acknowledgment information), or although the feedback information is obtained, but the feedback information is not ACK (Acknowledgment, confirmation information), it is determined that the state of the UE has not changed.

具体地，针对该步骤，首先可以通过上行HS-DPCCH获取该UE的反馈信息，该反馈信息可能为ACK或DTX。反馈信息可以存储在与基站通过HS-SCCH发送状态指令的帧所对应的上行帧中。如果未获取到反馈信息，则判断该UE的HS-SCCHless operation模式状态未改变；如果获取到的反馈信息是DTX(即不是ACK)，则也判断该UE的HS-SCCH less operation模式状态未改变；如果获取到反馈信息是ACK，则判断该UE的HS-SCCH less operation模式状态已经改变。Specifically, for this step, firstly, the feedback information of the UE may be obtained through the uplink HS-DPCCH, and the feedback information may be ACK or DTX. The feedback information may be stored in the uplink frame corresponding to the frame in which the base station sends the status instruction through the HS-SCCH. If no feedback information is obtained, it is judged that the state of the HS-SCCH less operation mode of the UE has not changed; if the obtained feedback information is DTX (that is, not ACK), it is also judged that the state of the HS-SCCH less operation mode of the UE has not changed ; If the acquired feedback information is ACK, it is judged that the state of the HS-SCCH less operation mode of the UE has changed.

503：如果该UE的状态未改变，在该UE的状态改变之前，按照预设的调度策略进行针对该UE的下行调度，在该UE的状态改变之后，执行步骤504；503: If the state of the UE has not changed, perform downlink scheduling for the UE according to a preset scheduling strategy before the state of the UE changes, and perform step 504 after the state of the UE changes;

其中，如果该UE的状态未改变，则在该UE的状态改变之前，按照预设的调度策略进行针对该UE的下行调度，该预设的调度策略保证下行调度行为与该UE采用的HS-SCCH less operation模式相符合。此处的预设的调度策略具体为：Wherein, if the state of the UE does not change, before the state of the UE changes, downlink scheduling for the UE is performed according to a preset scheduling strategy, and the preset scheduling strategy ensures that the downlink scheduling behavior is consistent with the HS- The SCCH less operation mode is consistent. The preset scheduling strategy here is specifically:

不进行针对该UE的下行调度；或，Do not perform downlink scheduling for the UE; or,

按照向该UE发送状态指令前原有的调度方式进行针对该UE的下行调度；或，Perform downlink scheduling for the UE according to the original scheduling method before sending the status instruction to the UE; or,

按照非HS-SCCH less operation模式进行针对该UE的下行调度。Perform downlink scheduling for the UE according to the non-HS-SCCH less operation mode.

具体地，不进行针对该UE的下行调度，即从向UE发送状态指令到UE的HS-SCCH less operation模式状态改变的时间间隔内，基站侧不再对该UE进行调度发送处理。同时，接收该UE发送的上行帧。Specifically, the downlink scheduling for the UE is not performed, that is, within the time interval from sending the status instruction to the UE to the HS-SCCH less operation mode status change of the UE, the base station side no longer performs scheduling and sending processing on the UE. At the same time, the uplink frame sent by the UE is received.

按照向该UE发送状态指令前原有的调度方式进行针对该UE的下行调度，即从向UE发送状态指令到UE的HS-SCCH less operation模式状态改变的时间间隔内，基站侧按照向该UE发送状态指令前原有的调度方式向该UE下发数据。同时，接收该UE发送的上行帧。The downlink scheduling for the UE is performed according to the original scheduling method before sending the status command to the UE, that is, within the time interval from sending the status command to the UE to the state change of the HS-SCCH less operation mode of the UE, the base station side sends to the UE according to the The original scheduling method before the status command sends data to the UE. At the same time, the uplink frame sent by the UE is received.

按照非HS-SCCH less operation模式进行针对该UE的下行调度，即从向UE发送状态指令到UE的HS-SCCH less operation模式状态改变的时间间隔内，基站侧按照非HS-SCCH less operation模式(即原有方式)调度该UE，向该UE下发数据。同时，接收该UE发送的上行帧。The downlink scheduling for the UE is performed according to the non-HS-SCCH less operation mode, that is, within the time interval from sending the status instruction to the UE to the UE's HS-SCCH less operation mode state change, the base station side follows the non-HS-SCCH less operation mode ( That is, the original method) schedules the UE, and delivers data to the UE. At the same time, the uplink frame sent by the UE is received.

在实际应用中，可以选择上述三种预设的调度策略中的任意一种来实施。In practical applications, any one of the above three preset scheduling strategies can be selected for implementation.

进一步地，UE的状态未改变包括两种情况：Further, the status of the UE has not changed includes two situations:

第一种情况是未获取到反馈信息，此种情况下，继续获取反馈信息；The first case is that the feedback information is not obtained, in this case, continue to obtain the feedback information;

第二种情况是获取到了反馈信息但不是ACK，此种情况下，可以重复执行向UE发送状态指令的步骤。The second case is that the feedback information is obtained but not the ACK. In this case, the step of sending the status instruction to the UE may be repeated.

在第二种情况下，当重复执行向UE发送状态指令的步骤的次数超过最大重传次数后，可以按照向该UE发送状态指令前原有的调度方式进行针对该UE的下行调度。其中，本发明实施例不对最大重传次数进行具体限定，可以根据实际情况进行设定，如可以设为4次。In the second case, when the number of repeated executions of the step of sending the status instruction to the UE exceeds the maximum number of retransmissions, downlink scheduling for the UE may be performed according to the original scheduling method before sending the status instruction to the UE. Wherein, the embodiment of the present invention does not specifically limit the maximum number of retransmissions, which can be set according to actual conditions, for example, it can be set to 4 times.

总之，无论未获取到反馈信息或获取到的反馈信息为DTX，又或者重复执行向UE发送状态指令的过程当中，该UE的状态均未改变，在该UE的状态改变之前，按照预设的调度策略进行针对该UE的下行调度，并在该UE的状态改变之后，执行步骤504。In short, no matter whether the feedback information is not obtained or the obtained feedback information is DTX, or the process of sending the status instruction to the UE is repeated, the state of the UE does not change. Before the state of the UE changes, according to the preset The scheduling policy performs downlink scheduling for the UE, and after the state of the UE changes, step 504 is executed.

504：如果该UE的状态已改变，则按照状态指令指定的状态进行针对该UE的下行调度，流程结束；504: If the state of the UE has changed, perform downlink scheduling for the UE according to the state specified by the state instruction, and the process ends;

具体地，一旦确定UE的状态发生改变，基站则按照状态指令指定的HS-SCCHless operation模式或非HS-SCCH less operation模式，进行针对该UE的下行调度。比如，如果UE状态改变后为HS-SCCH less operation模式，则可以采用HS-SCCH less operation方式或原有方式进行针对该UE的下行调度；如果UE状态改变后为非HS-SCCH less operation模式，则采用原有方式进行针对该UE的下行调度。Specifically, once it is determined that the state of the UE has changed, the base station performs downlink scheduling for the UE according to the HS-SCCH less operation mode or non-HS-SCCH less operation mode specified by the state instruction. For example, if the UE status changes to HS-SCCH less operation mode, the HS-SCCH less operation method or the original method can be used to perform downlink scheduling for the UE; if the UE status changes to non-HS-SCCH less operation mode, Then, the downlink scheduling for the UE is performed in the original way.

另一方面，当UE的状态改变后，立即按照改变后的状态进行上行HS-DPCCH帧发送。On the other hand, when the state of the UE changes, the uplink HS-DPCCH frame is sent immediately according to the changed state.

进一步地，针对本发明实施例提供的方法，具体举例说明如下：Further, for the methods provided in the embodiments of the present invention, specific examples are as follows:

每个帧占用的时间为1个TTI，1TTI＝3slot(时隙)。基站完全下发一条状态指令需要1个TTI，状态指令完全下发后的4个TTI后UE返回反馈信息。当针对某一UE发送状态指令后，根据UE的反馈信息是否为ACK判断UE的状态是否改变，按照定时关系分以下两种情况进行处理：The time occupied by each frame is 1 TTI, 1 TTI = 3 slots (time slots). It takes 1 TTI for the base station to fully issue a status command, and the UE returns feedback information after 4 TTIs after the status command is fully delivered. After sending a status command for a certain UE, it is judged whether the status of the UE has changed according to whether the feedback information of the UE is ACK, and the following two cases are processed according to the timing relationship:

第一种情况：反馈信息是ACK，参见图3：The first case: the feedback information is ACK, see Figure 3:

在第1个TTI，通过HS-SCCH向UE发送状态指令；In the first TTI, send a status instruction to the UE through HS-SCCH;

在第1至第5个TTI内未获取到反馈信息，这段时间间隔内UE的状态未改变，根据预设的调度策略进行针对该UE的下行调度；No feedback information is obtained within the 1st to 5th TTI, and the state of the UE does not change during this time interval, and the downlink scheduling for the UE is performed according to the preset scheduling strategy;

在第6个TTI，基站获取到UE的反馈信息，该反馈信息从UE通过上行HS-DPCCH发送的与HS-SCCH的状态指令对应的帧中获取，并判断为ACK；In the sixth TTI, the base station obtains the feedback information of the UE, which is obtained from the frame corresponding to the HS-SCCH status command sent by the UE through the uplink HS-DPCCH, and is judged as ACK;

在第6个TTI，基站开始按照状态指令指定的HS-SCCH less operation模式状态进行针对该UE的下行调度；In the sixth TTI, the base station starts to perform downlink scheduling for the UE according to the HS-SCCH less operation mode state specified by the state instruction;

UE的HS-SCCH less operation模式状态改变后立即按照改变后的状态进行上行HS-DPCCH帧发送。After the HS-SCCH less operation mode state of the UE changes, the uplink HS-DPCCH frame is sent immediately according to the changed state.

第二种情况：反馈信息是DTX，参见图4：The second case: the feedback information is DTX, see Figure 4:

在第1个TTI，通过HS-SCCH向UE发送状态指令；In the first TTI, send a status instruction to the UE through HS-SCCH;

在第1至第5个TTI内未获取到反馈信息，这段时间间隔内UE的状态未改变，根据预设的调度策略进行针对该UE的下行调度；No feedback information is obtained within the 1st to 5th TTI, and the state of the UE does not change during this time interval, and the downlink scheduling for the UE is performed according to the preset scheduling policy;

在第6个TTI，基站获取到UE的反馈信息，该反馈信息从UE通过上行HS-DPCCH发送的与HS-SCCH的状态指令对应的帧中获取，并判断为DTX；In the sixth TTI, the base station obtains the feedback information of the UE, which is obtained from the frame corresponding to the HS-SCCH status instruction sent by the UE through the uplink HS-DPCCH, and is judged as DTX;

在第7个TTI向UE重传状态指令；Retransmit the status command to the UE at the seventh TTI;

在第6×N+6(N为大于等于1的自然数，N表示重传次数)个TTI基站获取到UE的反馈信息，该反馈信息从UE通过上行HS-DPCCH发送的与HS-SCCH的状态指令对应的帧中获取，对该反馈信息进行判断：At the 6th×N+6 (N is a natural number greater than or equal to 1, and N represents the number of retransmissions) TTI base station obtains the feedback information of the UE, which is sent by the UE through the uplink HS-DPCCH and the state of the HS-SCCH Get it in the frame corresponding to the instruction, and judge the feedback information:

如果判断为ACK，则按第一种情况进行处理，即在第6×N+6(N为大于等于1的自然数，N表示重传次数)个TTI基站开始按照状态指令指定的状态进行针对该UE的下行调度，该UE的状态改变后立即按照改变后的状态通过上行HS-DPCCH进行帧的发送；If it is judged to be ACK, it will be processed according to the first case, that is, at the 6th×N+6 (N is a natural number greater than or equal to 1, and N represents the number of retransmissions) TTI base stations start to target the state according to the state specified by the state instruction. Downlink scheduling of the UE, after the state of the UE changes, the frame is sent through the uplink HS-DPCCH immediately according to the changed state;

如果判断为DTX，则继续向UE重传状态指令，其中从第1个TTI至收到ACK(即UE的状态改变)或达到最大重传次数期间，都根据预设的调度策略进行针对该UE的下行调度。If it is judged to be DTX, continue to retransmit the status instruction to the UE. From the first TTI to receiving the ACK (that is, the state of the UE changes) or reaching the maximum number of retransmissions, the UE is targeted according to the preset scheduling strategy. downscheduling.

当重传的次数超过最大重传次数后，按照向UE发送状态指令前原有的调度方式进行针对该UE的下行调度。When the number of retransmissions exceeds the maximum number of retransmissions, the downlink scheduling for the UE is performed according to the original scheduling method before sending the status instruction to the UE.

本发明实施例提供的方法，通过从发送状态指令到UE的状态改变之前的时间间隔内，按照预设的调度策略进行针对该UE的下行调度，明确了基站通过HS-SCCH发送激活或去激活的指令后调度设备侧和UE侧的行为，使调度设备的下行调度行为与UE的状态相符合，提高了系统的性能，具体如下：In the method provided by the embodiment of the present invention, the downlink scheduling for the UE is performed according to the preset scheduling strategy within the time interval from sending the status command to before the UE status changes, and it is clarified that the base station sends activation or deactivation through the HS-SCCH The behavior of the scheduling device side and the UE side after the instruction is given, so that the downlink scheduling behavior of the scheduling device is consistent with the state of the UE, and the performance of the system is improved. The details are as follows:

当预设的策略为从发送状态指令到UE的状态改变的时间间隔内，不进行针对该UE的下行调度时，简化了系统实现，使基站侧的数据调度和接收与UE状态始终保持一致，避免了可能出现的数据帧的丢失以至于引起高层重传；同时，基站侧可以在不调度该UE的时间段内调度其他UE，提高基站下行吞吐率，提升了系统性能。When the preset strategy is to not perform downlink scheduling for the UE within the time interval from sending the status instruction to the UE status change, the system implementation is simplified, and the data scheduling and reception on the base station side are always consistent with the UE status. It avoids the possible loss of data frames and causes high-level retransmission; at the same time, the base station side can schedule other UEs during the time period when the UE is not scheduled, which improves the downlink throughput of the base station and improves system performance.

当预设的策略为从发送状态指令到UE的状态改变的时间间隔内，按照向UE发送状态指令前原有的调度方式进行针对该UE的下行调度时，尽可能降低了基站侧处理的复杂度；在UE返回ACK之前，对UE的调度不做改变，在信道条件较好的情况下，小区的吞吐率以及系统容量不会下降。When the preset strategy is to perform downlink scheduling for the UE according to the original scheduling method before sending the status command to the UE within the time interval from sending the status command to the UE status change, the complexity of processing on the base station side is reduced as much as possible ; Before the UE returns an ACK, the scheduling of the UE will not be changed, and the throughput rate of the cell and the system capacity will not decrease when the channel condition is good.

当预设的策略为从发送状态指令到UE的状态改变的时间间隔内，按照非HS-SCCH less operation模式进行针对该UE的下行调度时，无论UE状态是从HS-SCCH less operation模式转换到非HS-SCCH less operation模式，还是从非HS-SCCH less operation模式转换到HS-SCCH less operation模式，UE都可以进行非HS-SCCH less operation方式(即原有方式)的数据接收，这样避免了采用HS-SCCH less operation方式调度发送在激活去激活过程中可能出现的丢帧。When the preset strategy is to perform downlink scheduling for the UE according to the non-HS-SCCH less operation mode within the time interval from sending the status instruction to the UE status change, regardless of whether the UE status is switched from HS-SCCH less operation mode to Non-HS-SCCH less operation mode, or switching from non-HS-SCCH less operation mode to HS-SCCH less operation mode, UE can receive data in non-HS-SCCH less operation mode (that is, the original mode), which avoids The HS-SCCH less operation method is used to schedule and transmit the frame loss that may occur during the activation and deactivation process.

本发明实施例提供了一种调度设备，该设备除了适用于WCDMA和TDSCDMA系统之外，还可以应用于其他通信系统。本发明实施例仅以WCDMA中的基站作为调度设备调度UE为例进行说明，但不限定于此。在WCDMA系统中，针对R9版本协议中的DC HSDPA用户，当向UE发送辅载波激活指令时，是要将UE的SCHSDPA状态激活为DC HSDPA状态；当向UE发送辅载波去激活指令时，是要将UE的DC HSDPA状态去激活为SC HSDPA状态；针对R7版本协议中的HSDPA用户，当向UE发送HS-SCCH less operation模式激活指令时，是要将UE从原有模式激活为HS-SCCH less operation模式；当向UE发送HS-SCCH less operation模式去激活指令时，是要将UE从HS-SCCH less operation模式去激活为原有模式。The embodiment of the present invention provides a scheduling device, which can be applied to other communication systems besides WCDMA and TDSCDMA systems. The embodiment of the present invention is only described by taking the base station in WCDMA as the scheduling device to schedule the UE as an example, but it is not limited thereto. In the WCDMA system, for DC HSDPA users in the R9 version protocol, when sending the secondary carrier activation instruction to the UE, it is necessary to activate the SCHSDPA state of the UE to the DC HSDPA state; when sending the secondary carrier deactivation instruction to the UE, it is It is necessary to deactivate the DC HSDPA state of the UE to the SC HSDPA state; for HSDPA users in the R7 protocol, when the HS-SCCH less operation mode activation command is sent to the UE, it is necessary to activate the UE from the original mode to HS-SCCH Less operation mode; when sending the HS-SCCH less operation mode deactivation command to the UE, it is to deactivate the UE from the HS-SCCH less operation mode to the original mode.

参见图6，该设备包括：Referring to Figure 6, the device includes:

发送模块601，用于向HSDPA UE发送状态指令，该状态指令包括激活指令或去激活指令；Sendingmodule 601, is used for sending status instruction to HSDPA UE, and this status instruction includes activation instruction or deactivation instruction;

判断模块602，用于在发送模块601向HSDPA UE发送状态指令后，判断该UE的状态是否改变；Judgment module 602, for after sendingmodule 601 to HSDPA UE sends state order, judges whether the state of this UE changes;

调度模块603，用于在判断模块602判断该UE的状态改变之前，按照预设的调度策略进行针对该UE的下行调度，该预设的调度策略保证下行调度行为与该UE的状态相符合。Thescheduling module 603 is configured to perform downlink scheduling for the UE according to a preset scheduling policy before the judgingmodule 602 judges that the state of the UE changes. The preset scheduling policy ensures that the downlink scheduling behavior is consistent with the state of the UE.

其中，当该UE为DC HSDPA用户设备时，发送模块601向该UE发送的状态指令具体包括辅载波激活指令或辅载波去激活指令。当向UE发送辅载波激活指令时，是要将UE的SC HSDPA状态激活为DC HSDPA状态；当向UE发送辅载波去激活指令时，是要将UE的DC HSDPA状态去激活为SC HSDPA状态。Wherein, when the UE is a DC HSDPA user equipment, the status instruction sent by the sendingmodule 601 to the UE specifically includes a secondary carrier activation instruction or a secondary carrier deactivation instruction. When sending the secondary carrier activation instruction to the UE, it is necessary to activate the SC HSDPA state of the UE to the DC HSDPA state; when sending the secondary carrier deactivation instruction to the UE, it is to deactivate the DC HSDPA state of the UE to the SC HSDPA state.

相应地，该预设的调度策略保证在辅载波上的调度行为与该UE的辅载波状态相符合，调度模块603按照预设的调度策略进行针对该UE的下行调度的具体方式为：不进行针对该UE的下行调度；或，按照向该UE发送状态指令前原有的调度方式进行针对该UE的下行调度；或，只在主载波进行针对该UE的下行调度。具体地，不进行针对该UE的下行调度，即从向UE发送状态指令到UE的辅载波状态改变的时间间隔内，基站侧不通过主载波和辅载波针向该UE下发任何调度的数据。同时，接收该UE发送的上行帧。按照向该UE发送状态指令前原有的调度方式进行针对该UE的下行调度，即从向UE发送状态指令到UE的辅载波状态改变的时间间隔内，基站侧按照向该UE发送状态指令前原有的调度方式向该UE下发数据。同时，接收该UE发送的上行帧。只在主载波进行针对该UE的下行调度，即从向UE发送状态指令到UE的辅载波状态改变的时间间隔内，基站侧只通过主载波调度该UE，向该UE下发数据。同时，接收该UE发送的上行帧。在实际应用中，可以选择上述三种预设的调度策略中的任意一种来实施。Correspondingly, the preset scheduling strategy ensures that the scheduling behavior on the secondary carrier is consistent with the UE's secondary carrier state, and thescheduling module 603 performs downlink scheduling for the UE according to the preset scheduling strategy in a specific way: no The downlink scheduling for the UE; or, performing the downlink scheduling for the UE according to the original scheduling method before sending the status instruction to the UE; or, performing the downlink scheduling for the UE only on the primary carrier. Specifically, the downlink scheduling for the UE is not performed, that is, within the time interval from sending the status instruction to the UE to the UE's secondary carrier status change, the base station side does not send any scheduled data to the UE through the primary carrier and the secondary carrier. . At the same time, the uplink frame sent by the UE is received. The downlink scheduling for the UE is performed according to the original scheduling method before sending the status command to the UE, that is, within the time interval from sending the status command to the UE to the change of the secondary carrier status of the UE, the base station side follows the original scheduling method before sending the status command to the UE. The scheduling mode is used to deliver data to the UE. At the same time, the uplink frame sent by the UE is received. The downlink scheduling for the UE is only performed on the primary carrier, that is, within the time interval from sending the state command to the UE to the UE's secondary carrier status change, the base station only schedules the UE through the primary carrier and delivers data to the UE. At the same time, the uplink frame sent by the UE is received. In practical applications, any one of the above three preset scheduling strategies can be selected for implementation.

当该UE为HSDPA用户设备时，发送模块601向该UE发送的状态指令具体包括HS-SCCH less operation模式激活指令或HS-SCCH less operation模式去激活指令。当向UE发送HS-SCCH less operation模式激活指令时，是要将UE从原有模式激活为HS-SCCH less operation模式；当向UE发送HS-SCCH lessoperation模式去激活指令时，是要将UE从HS-SCCH less operation模式去激活为原有模式。当UE的状态在HS-SCCH less operation模式下，UE既可以按照HS-SCCH less operation方式接收数据，也可以按照原有方式，即非HS-SCCHless operation方式接收数据。但是如果UE的状态在非HS-SCCH less operation模式下，那么UE按照非HS-SCCH less operation方式接收数据。因此，基站对于处于HS-SCCH less operation模式下的UE，采用HS-SCCH less operation方式或原有方式都可以进行调度发送；而对于处于非HS-SCCH less operation模式下的UE，采用原有方式进行调度发送。When the UE is an HSDPA user equipment, the status instruction sent by the sendingmodule 601 to the UE specifically includes an HS-SCCH less operation mode activation instruction or an HS-SCCH less operation mode deactivation instruction. When sending the HS-SCCH less operation mode activation command to the UE, it is to activate the UE from the original mode to the HS-SCCH less operation mode; when sending the HS-SCCH less operation mode deactivation command to the UE, it is to activate the UE from the original mode The HS-SCCH less operation mode is deactivated to the original mode. When the state of the UE is in the HS-SCCH less operation mode, the UE can receive data in the HS-SCCH less operation mode, or in the original mode, that is, in the non-HS-SCCH less operation mode. However, if the state of the UE is in the non-HS-SCCH less operation mode, then the UE receives data in the non-HS-SCCH less operation mode. Therefore, for UEs in HS-SCCH less operation mode, the base station can use the HS-SCCH less operation method or the original method to schedule and send; and for the UE in non-HS-SCCH less operation mode, use the original method Make a scheduled send.

相应地，该预设的调度策略保证下行调度行为与该UE采用的HS-SCCH lessoperation模式相符合，调度模块603按照预设的调度策略进行针对该UE的下行调度的具体方式为：不进行针对该UE的下行调度；或，按照向该UE发送状态指令前原有的调度方式进行针对该UE的下行调度；或，按照非HS-SCCH lessoperation模式进行针对该UE的下行调度。具体地，不进行针对该UE的下行调度，即从向UE发送状态指令到UE的HS-SCCH less operation模式状态改变的时间间隔内，基站侧不再对该UE进行调度发送处理。同时，接收该UE发送的上行帧。按照向该UE发送状态指令前原有的调度方式进行针对该UE的下行调度，即从向UE发送状态指令到UE的HS-SCCH less operation模式状态改变的时间间隔内，基站侧按照向该UE发送状态指令前原有的调度方式向该UE下发数据。同时，接收该UE发送的上行帧。按照非HS-SCCH less operation模式进行针对该UE的下行调度，即从向UE发送状态指令到UE的HS-SCCH lessoperation模式状态改变的时间间隔内，基站侧按照非HS-SCCH less operation模式(即原有方式)调度该UE，向该UE下发数据。同时，接收该UE发送的上行帧。在实际应用中，可以选择上述三种预设的调度策略中的任意一种来实施。Correspondingly, the preset scheduling strategy ensures that the downlink scheduling behavior is consistent with the HS-SCCH lessoperation mode adopted by the UE, and thescheduling module 603 performs downlink scheduling for the UE according to the preset scheduling strategy in a specific manner: no targeting The downlink scheduling of the UE; or, the downlink scheduling for the UE is performed according to the original scheduling method before sending the status instruction to the UE; or, the downlink scheduling for the UE is performed according to the non-HS-SCCH lessoperation mode. Specifically, the downlink scheduling for the UE is not performed, that is, within the time interval from sending the status instruction to the UE to the HS-SCCH less operation mode status change of the UE, the base station side no longer performs scheduling and sending processing on the UE. At the same time, the uplink frame sent by the UE is received. The downlink scheduling for the UE is performed according to the original scheduling method before sending the status command to the UE, that is, within the time interval from sending the status command to the UE to the state change of the HS-SCCH less operation mode of the UE, the base station side sends to the UE according to the The original scheduling method before the status command sends data to the UE. At the same time, the uplink frame sent by the UE is received. The downlink scheduling for the UE is performed according to the non-HS-SCCH less operation mode, that is, within the time interval from sending the status command to the UE to the change of the state of the HS-SCCH less operation mode of the UE, the base station side follows the non-HS-SCCH less operation mode (ie The original method) schedules the UE, and delivers data to the UE. At the same time, the uplink frame sent by the UE is received. In practical applications, any one of the above three preset scheduling strategies can be selected for implementation.

具体地，判断模块602，具体用于根据是否获取到该UE的确认信息来判断该UE的状态是否改变，如果未获取到该UE的反馈信息或获取到的反馈信息不是确认信息，则判断该UE的状态未改变。Specifically, the judgingmodule 602 is specifically configured to judge whether the state of the UE has changed according to whether the confirmation information of the UE is obtained, and if the feedback information of the UE is not obtained or the obtained feedback information is not confirmation information, then judge the The state of the UE has not changed.

进一步地，UE的状态未改变包括两种情况：第一种情况是未获取到反馈信息，此种情况下，继续获取反馈信息；第二种情况是获取到了反馈信息但不是ACK，此种情况下，参见图7，该设备还包括：Further, the status of the UE does not change includes two cases: the first case is that the feedback information is not obtained, in this case, continue to obtain the feedback information; the second case is that the feedback information is obtained but not ACK, in this case Next, see Figure 7, the device also includes:

重传模块604，用于在判断模块602获取到的反馈信息不是ACK，则判断该UE的状态未改变之后，重复执行发送模块601向UE发送状态指令的步骤。Theretransmission module 604 is configured to repeatedly execute the step of sending the status instruction to the UE by the sendingmodule 601 after judging that the status of the UE has not changed if the feedback information obtained by the judgingmodule 602 is not ACK.

更进一步地，参见图8，该设备还包括：Further, referring to Figure 8, the device also includes:

还原模块605，用于当重传模块604重复执行发送模块601向UE发送状态指令的步骤的次数超过最大重传次数后，按照发送模块601向该UE发送状态指令前原有的调度方式进行针对该UE的下行调度。其中，本发明实施例不对最大重传次数进行具体限定，可以根据实际情况进行设定，如可以设为4次。Restoremodule 605, configured to perform theretransmission module 604 according to the original scheduling method before the sendingmodule 601 sends the status instruction to the UE after the number of times that the sendingmodule 601 repeatedly executes the step of sending the status instruction to the UE exceeds the maximum number of retransmissions. Downlink scheduling of UE. Wherein, the embodiment of the present invention does not specifically limit the maximum number of retransmissions, which can be set according to actual conditions, for example, it can be set to 4 times.

另一方面，如果该UE的状态已改变，则调度模块603按照状态指令指定的状态进行针对该UE的下行调度，此时UE按照改变后的状态进行上行HS-DPCCH帧发送。On the other hand, if the state of the UE has changed, thescheduling module 603 performs downlink scheduling for the UE according to the state specified by the state instruction, and at this time, the UE transmits the uplink HS-DPCCH frame according to the changed state.

本发明实施例提供的调度设备中的模块在实际应用时，具体举例说明如下：When the modules in the scheduling device provided by the embodiments of the present invention are used in practice, specific examples are as follows:

每个帧占用的时间为1个TTI，1TTI＝3slot(时隙)。发送模块601完全下发一条状态指令需要1个TTI，状态指令完全下发后的4个TTI后UE返回反馈信息。当针对某一UE发送状态指令后，根据UE的反馈信息是否为ACK判断UE的状态是否改变，按照定时关系分以下两种情况进行处理：The time occupied by each frame is 1 TTI, 1 TTI = 3 slots (time slots). It takes 1 TTI for the sendingmodule 601 to completely deliver a status command, and the UE returns feedback information after 4 TTIs after the status command is completely delivered. After sending a status command for a certain UE, it is judged whether the status of the UE has changed according to whether the feedback information of the UE is ACK, and the following two cases are processed according to the timing relationship:

第一种情况：反馈信息是ACK，参见图3：The first case: the feedback information is ACK, see Figure 3:

在第1个TTI，发送模块601通过HS-SCCH向UE发送状态指令；In the first TTI, the sendingmodule 601 sends a status instruction to the UE through the HS-SCCH;

在第1至第5个TTI内未获取到反馈信息，判断模块602判断该UE的状态未改变，这段时间间隔内，调度模块603按照预设的调度策略进行针对该UE的下行调度；No feedback information is obtained within the 1st to 5th TTI, and the judgingmodule 602 judges that the state of the UE has not changed. During this time interval, thescheduling module 603 performs downlink scheduling for the UE according to a preset scheduling strategy;

在第6个TTI，基站获取到UE的反馈信息，该反馈信息从UE通过上行HS-DPCCH发送的与HS-SCCH的状态指令对应的帧中获取，并通过判断模块602判断为ACK，则从第6个TTI开始，调度模块603开始按照状态指令指定的状态进行针对该UE的下行调度。同时，UE的状态改变后立即按照改变后的状态进行上行HS-DPCCH帧发送。In the sixth TTI, the base station obtains the feedback information of the UE, which is obtained from the frame corresponding to the HS-SCCH status instruction sent by the UE through the uplink HS-DPCCH, and is judged as ACK by thejudgment module 602, then from Starting from the sixth TTI, thescheduling module 603 starts to perform downlink scheduling for the UE according to the state specified by the state instruction. At the same time, immediately after the state of the UE changes, the uplink HS-DPCCH frame is sent according to the changed state.

第二种情况：反馈信息不是ACK，参见图4：The second case: the feedback information is not ACK, see Figure 4:

在第1个TTI，发送模块601通过HS-SCCH向UE发送状态指令；In the first TTI, the sendingmodule 601 sends a status instruction to the UE through the HS-SCCH;

在第1至第5个TTI内未获取到反馈信息，判断模块602判断该UE的状态未改变，这段时间间隔内，调度模块603按照预设的调度策略进行针对该UE的下行调度；No feedback information is obtained within the 1st to 5th TTI, and the judgingmodule 602 judges that the state of the UE has not changed. During this time interval, thescheduling module 603 performs downlink scheduling for the UE according to a preset scheduling policy;

在第6个TTI，基站获取到UE的反馈信息，该反馈信息从UE通过上行HS-DPCCH发送的与HS-SCCH的状态指令对应的帧中获取，并通过判断模块602判断为不是ACK；In the 6th TTI, the base station obtains the feedback information of the UE, which is obtained from the frame corresponding to the HS-SCCH status instruction sent by the UE through the uplink HS-DPCCH, and is judged by thejudgment module 602 to be not ACK;

在第7个TTI，重传模块604向UE重传状态指令；In the seventh TTI, theretransmission module 604 retransmits the status instruction to the UE;

在第6×N+6(N为大于等于1的自然数，N表示重传次数)个TTI基站获取到UE的反馈信息，该反馈信息从UE通过上行HS-DPCCH发送的与HS-SCCH的状态指令对应的帧中获取，判断模块602对该反馈信息进行判断：At the 6th×N+6 (N is a natural number greater than or equal to 1, and N represents the number of retransmissions) TTI base station obtains the feedback information of the UE, which is sent by the UE through the uplink HS-DPCCH and the state of the HS-SCCH The frame corresponding to the instruction is obtained, and the judgingmodule 602 judges the feedback information:

如果判断为ACK，则按第一种情况进行处理，即在第6×N+6(N为大于等于1的自然数，N表示重传次数)个TTI开始按照状态指令指定的状态进行针对该UE的下行调度，该UE的状态改变后立即按照改变后的状态通过上行HS-DPCCH进行帧的发送；If it is judged to be ACK, it will be processed according to the first case, that is, at the 6th×N+6 (N is a natural number greater than or equal to 1, and N represents the number of retransmissions) TTIs, start to target the UE according to the state specified by the state instruction The downlink scheduling of the UE, after the state of the UE is changed, immediately transmits the frame through the uplink HS-DPCCH according to the changed state;

如果判断为不是ACK，则继续向UE重传状态指令，其中从第1个TTI至收到ACK(即UE的状态改变)或达到最大重传次数期间，都根据预设的调度策略进行针对该UE的下行调度。If it is judged not to be ACK, then continue to retransmit the status instruction to the UE. During the period from the first TTI to receiving the ACK (that is, the state of the UE changes) or reaching the maximum number of retransmissions, the preset scheduling strategy is used to target the instruction. Downlink scheduling of UE.

当重传的次数超过最大重传次数后，用还原模块605按照发送模块601向该UE发送状态指令前原有的调度方式进行针对该UE的下行调度。When the number of retransmissions exceeds the maximum number of retransmissions, therestoration module 605 performs downlink scheduling for the UE according to the original scheduling method before the sendingmodule 601 sends the status instruction to the UE.

本发明实施例提供的设备，通过从发送状态指令到UE的状态改变之前的时间间隔内，按照预设的调度策略进行针对该UE的下行调度，明确了基站通过HS-SCCH发送激活或去激活的指令后调度设备侧和UE侧的行为，使调度设备的下行调度行为与UE的状态相符合，提高了系统的性能。The device provided by the embodiment of the present invention performs downlink scheduling for the UE according to the preset scheduling policy within the time interval from sending the status instruction to before the UE status changes, and it is clear that the base station transmits activation or deactivation through the HS-SCCH The behaviors of the scheduling device side and the UE side after the instruction are made, so that the downlink scheduling behavior of the scheduling device is consistent with the state of the UE, and the performance of the system is improved.
