确定服务授权信息的方法和用户设备Method and user equipment for determining service authorization information

技术领域technical field

本发明涉及通信技术领域，特别涉及一种确定服务授权信息的方法和用户设备。The present invention relates to the field of communication technology, in particular to a method for determining service authorization information and user equipment.

背景技术Background technique

在UL-MIMO(UpLink Multiple Input Multiple Output，上行多输入多输出)通信系统中，UE(User Equipment，用户设备)与基站之间传输的数据流以为双数据流(简称为双流)或单数据流(简称为单流)。双流是指基站每次调度两个不同的数据块，其中一个是主数据块，一个是辅数据块，主数据块对应的数据流称为主流，主流承载在E-DPDCH(E-DCHDedicated Physical Data Channel，E-DCH专用物理数据信道)上，辅数据块对应的数据流称为辅流，辅流承载在S-E-DPDCH(Secondary E-DCH Dedicated Physical Data Channel，辅E-DCH专用物理数据信道)上。单流是指基站每次调度一个数据块。基站下发控制信息来进行UE调度，控制信息包括流指示、预编码矩阵相关信息和调度授权相关信息，UE根据这些控制信息确定发送流的个数，预编码矩阵，同时确定单流或者双流的主辅流的服务授权。In the UL-MIMO (UpLink Multiple Input Multiple Output, uplink multiple input multiple output) communication system, the data stream transmitted between the UE (User Equipment, user equipment) and the base station is double data stream (referred to as dual stream) or single data stream (referred to as single stream). Dual stream means that the base station schedules two different data blocks each time, one of which is the main data block and the other is the auxiliary data block. Channel, E-DCH Dedicated Physical Data Channel), the data stream corresponding to the secondary data block is called the secondary stream, and the secondary stream is carried on the S-E-DPDCH (Secondary E-DCH Dedicated Physical Data Channel, secondary E-DCH dedicated physical data channel) superior. Single stream means that the base station schedules one data block each time. The base station sends control information to perform UE scheduling. The control information includes flow indication, precoding matrix related information, and scheduling authorization related information. The UE determines the number of transmission flows and precoding matrix according to these control information. Service authorization for main and auxiliary streams.

随着无线信道的变化和调度需求的影响，基站会根据不同的场景调度UE发送单流还是发送双流。如果UE当前为双流发送，但是基站指示UE进行单流发送，则UE需要从双流切换到单流；如果UE当前为单流发送，但是基站指示UE进行双流发送，则UE需要从单流切换到双流。With the change of the wireless channel and the impact of scheduling requirements, the base station will schedule the UE to send single stream or dual stream according to different scenarios. If the UE is currently sending dual-stream, but the base station instructs the UE to perform single-stream transmission, the UE needs to switch from dual-stream to single-stream; if the UE is currently transmitting single-stream, but the base station instructs the UE to perform dual-stream transmission, the UE needs to switch from single-stream to Shuangliu.

现有技术提供了基站调度UE双流发送的流程：基站下发授权值、E-TFCI(E-DCH TransportFormat Combination Indicator，增强专用信道传输格式组合指示)偏置值和该E-TFCI偏置值对应的数据流标识给UE，UE根据该授权值确定出该数据流标识所标识的数据流的传输块大小，根据该传输块大小与该E-TFCI偏置值，确定出另一个数据流的传输块大小，从而进行双流发送。The existing technology provides a process for the base station to schedule UE dual-stream transmission: the base station sends an authorization value, E-TFCI (E-DCH Transport Format Combination Indicator, enhanced dedicated channel transmission format combination indicator) offset value and the E-TFCI offset value corresponds to The UE identifies the data stream identified by the data stream, and the UE determines the transmission block size of the data stream identified by the data stream ID according to the authorization value, and determines the transmission of another data stream according to the transport block size and the E-TFCI offset value block size, enabling dual-stream transmission.

上述现有技术中基站下发的调度信息包括授权值、E-TFCI偏置值及数据流标识共三个参数，占用资源较多，信令开销较大。The scheduling information issued by the base station in the above prior art includes three parameters including authorization value, E-TFCI offset value, and data flow identifier, which occupy more resources and have higher signaling overhead.

所述SG映射表是SG值和索引值一一对应的表，根据SG映射表可以查找与SG对应的索引值，也以查找与索引值对应的SG，该表中的SG值均认为是量化后的SG值，不在该表中的SG值，可以认为是非量化的SG值。The SG mapping table is a one-to-one correspondence table between the SG value and the index value. According to the SG mapping table, the index value corresponding to the SG can be searched, and the SG corresponding to the index value can also be searched. The SG values in the table are all considered to be quantized After the SG value, the SG value not in the table can be regarded as the non-quantized SG value.

The correction value issued by the base station through high-level signaling can be used by the UE multiple times in general, and can be used to calculate the SG of different TTIs. The correction value issued by the base station through physical layer signaling is usually currently delivered by the base station and is used for current calculation of the SG by the UE.

本实施例提供的上述方法，通过接收基站下发的传输模式指示信息，并根据该传输模式指示信息和第一TTI的服务授权信息，以确定出指定TTI的服务授权信息，由于基站下发的控制信息占用资源较少，能够降低信令开销，且UE能够根据占用资源较少的控制信息，确定出服务授权信息。The above method provided by this embodiment determines the service authorization information of the specified TTI by receiving the transmission mode indication information issued by the base station, and according to the transmission mode indication information and the service authorization information of the first TTI.

The timing of the AG delivery can be determined by the base station according to its own needs.

Optionally, as an embodiment, the quality difference K may be the received SINR (Signal to Interference plus Noise Ratio, SINR) of S-E-DPDCH and E-DPDCH under the same transmission power of S-E-DPDCH and E-DPDCH ) ratio:

本领域技术人员容易想到，质量差异K也可以是其他形式，如信噪比的比值等。这些变化均落入本发明实施例的范围内。Those skilled in the art can readily imagine that the quality difference K can also be in other forms, such as the ratio of the signal-to-noise ratio. These changes all fall within the scope of the embodiments of the present invention.

本发明实施例对用户设备获取质量差异K的方式不作限制。例如，可选地，作为一个实施例，用户设备可接收基站下发的质量差异K的值，即由网络侧确定质量差异K的值并下发给用户设备。The embodiment of the present invention does not limit the manner in which the user equipment acquires the quality difference K. For example, optionally, as an embodiment, the user equipment may receive the value of the quality difference K sent by the base station, that is, the network side determines the value of the quality difference K and sends it to the user equipment.

可选地，作为另一实施例，用户设备可根据基站下发的控制信息确定所述信道质量差异K的值。Optionally, as another embodiment, the user equipment may determine the value of the channel quality difference K according to the control information delivered by the base station.

例如，如果基站下发的控制信息为主流和辅流的质量差异SD，且SD为线性值的比值，则K＝1/SD；For example, if the control information sent by the base station is the quality difference SD between the main stream and the auxiliary stream, and SD is the ratio of linear values, then K=1/SD;

如果基站下发的控制信息为辅流和主流的质量差异SD，且SD为dB值的比值，则

If the control information delivered by the base station is the quality difference SD between the secondary stream and the mainstream stream, and SD is the ratio of the dB value, then

如果基站下发的控制信息为主流和辅流的质量差异SD，且SD为dB值的比值，则$K={10}^{-\frac{\mathrm{SD}}{10}}.$If the control information delivered by the base station is the quality difference SD between the main stream and the auxiliary stream, and SD is the ratio of the dB value, then$K={10}^{-\frac{\mathrm{SD}}{10}}.$

本发明上述任一实施例中涉及的所述第二修正值可以为UE本地存储的修正值，或者基站通过高层信令下发的修正值，或基站通过物理层信令下发的修正值。其中，UE本地存储的修正值可以是UE与基站双方事先经过协商得到的。基站通过高层信令下发的修正值通常情况下UE可以使用多次，可以用来计算不同TTI的SG。基站通过物理层信令下发的修正值通常是基站当前下发的且用于UE当前计算SG。The second correction value involved in any of the above embodiments of the present invention may be a correction value locally stored by the UE, or a correction value sent by the base station through high-layer signaling, or a correction value sent by the base station through physical layer signaling. Wherein, the correction value locally stored by the UE may be obtained through negotiation between the UE and the base station in advance. The correction value issued by the base station through high-level signaling can be used by the UE multiple times in general, and can be used to calculate the SG of different TTIs. The correction value issued by the base station through physical layer signaling is usually currently delivered by the base station and is used for current calculation of the SG by the UE.

本实施例提供的上述方法，通过接收基站下发的传输模式指示信息，并根据该传输模式指示信息和第一TTI的服务授权信息，可以确定出指定TTI的服务授权信息，由于基站下发的控制信息占用资源较少，能够降低信令开销，且UE能够根据占用资源较少的控制信息，确定出服务授权信息。The above method provided by this embodiment can determine the service authorization information of the specified TTI by receiving the transmission mode indication information issued by the base station, and according to the transmission mode indication information and the service authorization information of the first TTI. The control information occupies less resources, which can reduce signaling overhead, and the UE can determine the service authorization information according to the control information occupying less resources.

本发明实施例中，UE根据第一TTI的主流SG和辅流SG确定指定TTI的主流SG和辅流SG，可以应用于基站指示UE进行预编码矩阵切换的场景。这种场景下，基站可以下发一个预编码矩阵切换指示和新的预编码矩阵给UE，UE收到后会与当前使用的预编码矩阵进行比较，如果不同，则触发预编码矩阵切换，并计算切换后的主流SG和辅流SG，该计算切换后的主流SG和辅流SG的过程就是上述方法中描述的过程，此处不赘述。In the embodiment of the present invention, the UE determines the main stream SG and the auxiliary stream SG of the specified TTI according to the main stream SG and the auxiliary stream SG of the first TTI, which can be applied to a scenario where the base station instructs the UE to switch the precoding matrix. In this scenario, the base station can issue a precoding matrix switching instruction and a new precoding matrix to the UE. After receiving it, the UE will compare it with the currently used precoding matrix. If it is different, it will trigger the precoding matrix switching, and Calculate the switched main stream SG and auxiliary stream SG. The process of calculating the switched main stream SG and auxiliary stream SG is the process described in the above method, and will not be repeated here.

Any SG_temp obtained based on the idea of the present invention belongs to the protection scope of the present invention within.

本实施例提供的上述方法，应用于基站指示UE双流传输，但是UE根据自身的条件自主决定进行单流传输的场景。UE根据主流SG和辅流SG计算出单流SG，从而进行单流发送，由于基站下发的控制信息占用资源较少，能够降低信令开销。The foregoing method provided in this embodiment is applicable to a scenario where the base station instructs the UE to perform dual-stream transmission, but the UE independently decides to perform single-stream transmission according to its own conditions. The UE calculates the single-stream SG based on the main stream SG and the auxiliary stream SG, so as to perform single-stream transmission. Since the control information delivered by the base station occupies less resources, the signaling overhead can be reduced.

参见图12，本发明实施例提供了一种确定服务授权信息的方法，包括：Referring to Figure 12, an embodiment of the present invention provides a method for determining service authorization information, including:

1201：接收基站下发的单流传输模式指示信息；1201: Receive the single-stream transmission mode indication information issued by the base station;

在UL-MIMO中，主流的SG用来确定主辅流的发送功率和主流的传输块大小，而辅流的SG仅用来确定辅流的传输块大小。也就是说，主辅流的发送功率相同，都由主流的SG确定。由于UE要进行数据的重传，因此，辅流传输块的大小是已知的，此时则无需计算出辅流SG，只计算出主流SG的大小即可。In UL-MIMO, the SG of the main stream is used to determine the transmit power of the main and auxiliary streams and the transport block size of the main stream, while the SG of the auxiliary stream is only used to determine the transport block size of the auxiliary stream. That is to say, the sending power of the main and auxiliary streams is the same and is determined by the SG of the main stream. Since the UE needs to retransmit data, the size of the transmission block of the auxiliary stream is known. At this time, there is no need to calculate the SG of the auxiliary stream, and only the size of the SG of the main stream is calculated.

本实施例提供的上述方法，应用于基站指示UE单流传输，但是UE根据自身的条件自主决定进行双流传输的场景。UE根据单流SG计算出主流SG，从而进行双流数据重传，由于基站下发的控制信息占用资源较少，能够降低信令开销。The foregoing method provided in this embodiment is applicable to a scenario where the base station instructs the UE to perform single-stream transmission, but the UE independently decides to perform dual-stream transmission according to its own conditions. The UE calculates the mainstream SG based on the single-stream SG to perform dual-stream data retransmission. Since the control information delivered by the base station occupies less resources, signaling overhead can be reduced.
