(Intermediate Radio Frequency, IRF) and Transceiver (Transceiver, TRX) play different beams for UEs with less mutual interference in different directions, which can realize simultaneous transmission of multiple UEs and further improve spectrum utilization.

应该理解的是，本申请实施例只是以高频频段为例对频段在无线通信系统中的应用进行说明，而不能理解为对应用于无线通信系统中的频段的限定。It should be understood that the embodiments of the present application only take a high frequency frequency band as an example to describe the application of the frequency band in the wireless communication system, and cannot be understood as a limitation on the frequency band applied in the wireless communication system.

其中，结合图2(图2为SU-MIMO的示意图)可知，当基站利用全部收发天线生成单波束指向该波束方向的UE _m时，称为SU-MIMO。其中，单束波Beam _m是由基站基于全部收发天线T _k生成的，且T _k＝TRX ₀～TRX _N-1。 Wherein, referring to FIG. 2 (FIG. 2 is a schematic diagram of SU-MIMO), it can be known that when the base station uses all the transmitting and receiving antennas to generate a single beam pointing to the UE _{m in} the beam direction, it is called SU-MIMO. The single beam Beam _m is generated by the base station based on all the transceiver antennas T _k , and T _k =TRX ₀ to TRX _N-1 .

又如，结合图3(图3为MU-MIMO的示意图)可知，当基站分别利用部分收发天线生成多波束指向不同波束方向的UE _m和UE _n时，称为MU-MIMO。其中，UE _m的多波束Beam _m是由基站基于部分收发天线T _l生成的，且T _l＝TRX ₀～TRX _m；UE _n的多波束Beam _n是由基站基于部分收发天线T _l生成的，且T _l＝TRX _n～TRX _N-1。 For another example, referring to FIG. 3 (FIG. 3 is a schematic diagram of MU-MIMO), it can be known that when the base station generates multiple beams directed to UE _m and UE _n in different beam directions by using some transceiver antennas, it is called MU-MIMO. Wherein, UE _m multibeam Beam _m is based on the portion of a transceiver antenna T _l produced by the base station, and _{_{_{T l = TRX 0 ~ TRX m}}} ; UE n multibeam Beam _n is a base station based on partially receiving antenna T _l generated, And T _l =TRX _n to TRX _N-1 .

值得说明的是，图3指示用于示范性地说明多波束Beam _m和/或Beam _n可能由哪部分天线生成，而不能理解为对生成多波束Beam _m和/或Beam _n的天线的限定。 It should be noted that, in FIG. 3 indicates an exemplary view for explaining the multi-beam Beam _m and / or may be generated by the Beam _n which part of an antenna, not to be construed as to generate a multi-beam Beam _m and / or an antenna defining Beam _n.

也就是说，UE _m的多波束Beam _m可以是由基站基于部分收发天线T _l＝TRX ₀～TRX _m生成的，也可以是由T _l＝TRX _n～TRX _N-1生成的，也可以是由如图3所示的收发天线的排列方式的偶数序号对应的收发天线生成的，也可以是由如图3所示的收发天线的排列方式的奇数序号对应的收发天线生成的，也可以是由各接收天线的极化生成的，也可以是由随机选择的部分收发天线生成的，也可以是基于需求、经验及试验等生成的，等等，本申请实施例不做限定。 That is to say, the multi-beam Beam _{m of} _{UE m} may be generated by the base station based on some transceiver antennas T _l =TRX ₀ ˜TRX _m , or may be generated by T _l =TRX _n ˜TRX _N−1 , or may be It is generated by the transceiver antennas corresponding to the even-numbered serial numbers of the arrangement of the transceiver antennas shown in FIG. It may be generated by the polarization of each receiving antenna, may also be generated by some randomly selected transceiver antennas, or may be generated based on requirements, experience, and experiments, etc., which are not limited in the embodiments of the present application.

为了提高信息传输的可靠性和有效性，通常在进行信息传输的时，可以基于权值对待传输信息进行传输，而基于上述示例可知，UE为不同的传输模式(即MU-MIMO传输模式和SU-MIMO传输模式)时，基站生成的波束并不相同，则对应的权值也就不同。In order to improve the reliability and effectiveness of information transmission, the information to be transmitted can usually be transmitted based on the weights during information transmission. Based on the above example, it can be seen that the UE is in different transmission modes (ie, the MU-MIMO transmission mode and the SU transmission mode). -MIMO transmission mode), the beams generated by the base station are not the same, and the corresponding weights are also different.

现结合图4对相关技术中确定权值的方法进行阐述如下：The method for determining weights in the related art will now be described in conjunction with FIG. 4 as follows:

S1：基站向UE发送高层配置(high layer configuration)，或者，基站向UE发送低层配置(w/wo low layer configuration)。S1: The base station sends a high layer configuration (high layer configuration) to the UE, or the base station sends a low layer configuration (w/wo low layer configuration) to the UE.

相应地，UE接收基站发送的高层配置或者低层配置。Correspondingly, the UE receives the high-level configuration or the low-level configuration sent by the base station.

S2：基站通过多套测量方案的遍历方式向终端设备发送CSI-RS。S2: The base station sends the CSI-RS to the terminal device by traversing multiple sets of measurement schemes.

相应地，UE接收基站发送的CSI-RS。Correspondingly, the UE receives the CSI-RS sent by the base station.

S3：UE根据CSI-RS进行CSI测量并生成CSI Report。S3: The UE performs CSI measurement according to the CSI-RS and generates a CSI Report.

S4：UE向基站发送CSI report。S4: The UE sends a CSI report to the base station.

相应的，基站接收UE发送的CSI report。Correspondingly, the base station receives the CSI report sent by the UE.

S5：基站根据CSI report确定权值。S5: The base station determines the weight according to the CSI report.

值得说明的是，UE可能动态灵活地在SU-MIMO传输模式和MU-MIMO传输模式之间切换。It is worth noting that the UE may switch between the SU-MIMO transmission mode and the MU-MIMO transmission mode dynamically and flexibly.

通过相关技术的方法，当UE动态灵活地在SU-MIMO传输模式和MU-MIMO传输模式之间切换时，由于在不同传输模式下分配到收发天线的数目和序号不同，需要根据具体传输模式进行CSI测量资源配置并进行测量结果上报。Through the method of the related art, when the UE dynamically and flexibly switches between the SU-MIMO transmission mode and the MU-MIMO transmission mode, since the number and sequence number of the transceiver antennas allocated to the different transmission modes are different, it needs to be performed according to the specific transmission mode. CSI measurement resource configuration and measurement result reporting.

例如，当UE为SU-MIMO传输模式时，UE分配了4根收发天线，则基站按照4Port 进行CSI测量资源配置；而当处于MU-MIMO时，UE分配了2根收发天线，则基站按照2Port进行CSI测量资源配置。For example, when the UE is in the SU-MIMO transmission mode, the UE allocates 4 transceiver antennas, and the base station configures CSI measurement resources according to 4Port; and when in MU-MIMO, the UE allocates 2 transceiver antennas, the base station according to 2Port Perform CSI measurement resource configuration.

由于无法预知UE的传输模式，即无法预先知道UE会采用MU-MIMO传输模式还是SU-MIMO传输模式(且不能预知为该UE分配的收发天线的序号)，因此，需要配置多套CSI测量方案进行遍历，提前准备好发送所需的权值，从而导致CSI资源开销较大等问题。Since the transmission mode of the UE cannot be predicted, that is, it cannot be known in advance whether the UE will adopt the MU-MIMO transmission mode or the SU-MIMO transmission mode (and the sequence number of the transmitting and receiving antennas allocated to the UE cannot be predicted), therefore, multiple sets of CSI measurement schemes need to be configured. The traversal is performed, and the weights required for transmission are prepared in advance, which leads to problems such as large CSI resource overhead.

本申请的发明人在经过创造地劳动之后，得到了本申请的发明构思：根据UE为SU-MIMO传输模式时的CSI report确定MU-MIMO传输模式时的权值。After creative work, the inventor of the present application has obtained the inventive concept of the present application: determining the weight in the MU-MIMO transmission mode according to the CSI report when the UE is in the SU-MIMO transmission mode.

For example, if RI is 1, it means that only one independent signal can be transmitted; if RI is 2, then It means that two independent signals can be transmitted at the same time. The single- and dual-stream state of the UE can be determined according to the value of RI, that is, if RI=1, the UE is in a single-stream transmission state; if RI=2, the UE is in a dual-stream transmission state.
