技术领域Technical field

当终端在无线资源控制(Radio Resource Control，RRC)连接态时，终端需要持续的监听物理下行控制信道(Physical Downlink Control Channel，PDCCH)，以获知物理下行共享信道(Physical Downlink Shared Channel，PDSCH)的发送信息。终端持续的监听PDCCH必然导致用户设备(user equipment，UE)的快速耗电，因此，目前网络侧可以配置终端周期性地监控有无数据到来，在非连续性接收(Discontinuous Reception，DRX)的模式下，终端会周期性的监控数据信道，如果没有数据则进入到睡眠状态，以实现节约用电的目的。When the terminal is in the Radio Resource Control (RRC) connection state, the terminal needs to continuously monitor the Physical Downlink Control Channel (PDCCH) in order to learn the physical downlink shared channel (PDSCH). send Message.

Therefore, at present, the network side can be configured to periodically monitor the presence of data and the terminal is in a discontinuous reception (DRX) mode. Next, the terminal will periodically monitor the data channel, and enter the sleep state if there is no data to achieve the purpose of saving power.
然而对于5G NR系统来说，由于终端需要支持更大的宽带和更复杂的业务，较为耗电。However, for the 5G NR system, because the terminal needs to support larger bandwidth and more complex services, it consumes more power.

具体实施方式Detailed ways
为了使本申请的目的、技术方案和优点更加清楚明白，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。In order to make the purpose, technical solution, and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.
对于5G NR系统来说，由于支持更大的宽带和更复杂的业务，终端还是较为耗电。For the 5G NR system, the terminal still consumes more power because it supports larger broadband and more complex services.
鉴于此，本申请实施例考虑到终端选择收发天线的数目与功耗有关，更多的收发天线意味着更多的收发通道数,因而功耗较大。也就是终端的天线数越多,则收发通道越多,也会引起更大的功耗。如何有效的调整指示终端的收发天线数，进而调整终端的收发射频/基带通道数，是一个有效用于节省终端的功耗的技术方向。In view of this, the embodiment of the present application considers that the number of transmit / receive antennas selected by the terminal is related to power consumption. More transmit / receive antennas means more transmit / receive channels, and thus consumes more power. That is, the more antennas a terminal has, the more channels it can send and receive, and it will also cause greater power consumption. How to effectively adjust the number of transmitting and receiving antennas of the indicating terminal, and then adjust the number of transmitting / receiving RF / baseband channels of the terminal, is an effective technical direction for saving power consumption of the terminal.
为了降低终端的功耗，本申请实施例中的基站根据业务状态信息和/或信道质量信息或者终端反馈的指示生成天线配置信息。也就是基站根据终端要传输的数据量的大小生成天线配置信息，如果数据量较小，那么配置的天线配置信息指示的发送天线和/或接收天线的数目较少，从而达到节约用电的效果。或者基站根据信道质量的好坏程度生成天线配置信息，如果信道质量较好，那么配置的天线配置信息指示的发送天线和/或接收天线的数目较少，从而达到节约用电的效果。或者基站根据终端反馈的对功耗节省的需求生成天线配置信息，即基站是根据终端实际对功耗节省的需求从而生成的天线配置信息使得终端节约用电。相较于目前终端只通过周期性的监控数据信道来实现节约用电的方法，本申请实施例基站根据终端的实际传输数据量大小或者信道质量或终端对功耗节省的需求来指示终端选择收发天线数目，能够使得终端更加节约用电。In order to reduce the power consumption of the terminal, the base station in this embodiment of the present application generates antenna configuration information according to service status information and / or channel quality information or an indication fed back by the terminal. That is, the base station generates antenna configuration information according to the amount of data to be transmitted by the terminal. If the amount of data is small, the number of transmitting antennas and / or receiving antennas indicated by the configured antenna configuration information is small, thereby achieving the effect of saving power consumption. . Or the base station generates antenna configuration information according to the quality of the channel quality. If the channel quality is good, the number of transmitting antennas and / or receiving antennas indicated by the configured antenna configuration information is small, thereby achieving the effect of saving power consumption. Or the base station generates the antenna configuration information according to the demand for power saving saved by the terminal, that is, the base station generates the antenna configuration information according to the actual demand for power saving of the terminal, so that the terminal saves power. Compared to the current method for the terminal to save power by only periodically monitoring the data channel, the base station in the embodiment of the present application instructs the terminal to select the transceiver according to the actual amount of data transmitted by the terminal or the channel quality or the terminal ’s need for power saving. The number of antennas can make the terminal more power-efficient.
需要说明的是,实际应用中有可能多个物理天线对应一个天线端口,一个天线端口对应一个射频/基带通道数,但这不影响本申请,本申请的调整天线数目的配置意味着最终的结果是减少收发通道数,所以本申请所述的天线配置对应的是一种常规的做法,即一个天线对应一个物理的接收或发送通道。It should be noted that in actual applications, it is possible that multiple physical antennas correspond to one antenna port and one antenna port corresponds to one RF / baseband channel number, but this does not affect this application. The configuration of adjusting the number of antennas in this application means the final result It is to reduce the number of transmitting and receiving channels, so the antenna configuration described in this application corresponds to a conventional approach, that is, one antenna corresponds to one physical receiving or transmitting channel.
需要说明的是，本申请提供的天线配置方法，可以用于确定终端进行数据信道传输的发送天线数，也用于确定终端进行控制信道传输的接收天线数。It should be noted that the antenna configuration method provided in this application may be used to determine the number of transmitting antennas used by a terminal for data channel transmission, and also used to determine the number of received antennas used by a terminal for control channel transmission.
下面结合附图介绍本申请实施例提供的技术方案。The technical solutions provided by the embodiments of the present application are described below with reference to the drawings.
请参见图1，本申请实施例提供的一种天线配置信息的指示方法，该方法的流程描述如下。Referring to FIG. 1, a method for indicating antenna configuration information according to an embodiment of the present application is described below.
S101：基站根据业务状态信息和/或信道质量信息，或者根据终端反馈的 指示生成天线配置信息。S101: The base station generates antenna configuration information according to service status information and / or channel quality information, or according to an instruction fed back by the terminal.
在R15的规范里，终端的发送天线是半静态配置的，接收的天线数取决于终端的能力，因此是不可配置的。但是，天线数目和数据的收发通道数目是相关联的，更多的天线意味着更多的射频和基带处理通道，也就意味着终端的功耗更大。因此，本申请实施例为了使得终端节约功耗，可以指示终端较少的收发天线的数目，收发天线包括发送天线和接收天线。In the specification of R15, the transmitting antenna of the terminal is semi-statically configured, and the number of receiving antennas depends on the capabilities of the terminal, so it is not configurable. However, the number of antennas and the number of data transmitting and receiving channels are related. More antennas means more RF and baseband processing channels, which means that the power consumption of the terminal is greater. Therefore, in order to save power consumption of the terminal, the embodiment of the present application may indicate that the terminal has a small number of transmitting and receiving antennas. The transmitting and receiving antennas include a transmitting antenna and a receiving antenna.
具体地，基站可以根据终端的实际需求生成天线配置信息，其中，天线配置信息可以用于指示终端选择发送天线和/或接收天线的数目，从而指示终端选择收发天线的数目。本申请实施例中，基站确定终端的收发天线的数目可以有以下几种生成方式，下面一一进行介绍。Specifically, the base station may generate antenna configuration information according to the actual needs of the terminal, where the antenna configuration information may be used to instruct the terminal to select the number of transmit antennas and / or receive antennas, thereby instructing the terminal to select the number of transmit and receive antennas. In the embodiment of the present application, the base station may determine the number of transmitting and receiving antennas of the terminal in the following generation manners, which are described below one by one.
第一种生成方式：基站根据业务状态信息生成天线配置信息。The first generation method: the base station generates antenna configuration information according to the service status information.
业务状态信息可以用于指示终端要传输的数据量的大小，终端可以向基站反馈业务状态信息。当业务状态信息指示终端要传输的数据量较大，则基站生成的天线配置信息指示的收发天线的数目也较多，可以加快数据流的传输，而不影响对数据传输的性能。而当业务状态信息指示终端要传输的数据量较小，则无需太多的天线和收发通道，那么基站生成的天线配置信息指示的收发天线的数目也较少，可以达到降低功耗的目的。这样本申请实施例就既不影响对数据传输的性能，又能对终端的功耗进行控制，达到终端节约用电的目的。The service status information may be used to indicate the amount of data to be transmitted by the terminal, and the terminal may feedback the service status information to the base station. When the service status information indicates that the terminal has a large amount of data to transmit, the antenna configuration information generated by the base station indicates that the number of transmitting and receiving antennas is also large, which can speed up the transmission of the data stream without affecting the performance of data transmission. And when the service status information indicates that the terminal needs to transmit a small amount of data, it does not need too many antennas and transmitting and receiving channels, so the number of transmitting and receiving antennas indicated by the antenna configuration information generated by the base station is also small, which can achieve the purpose of reducing power consumption. In this way, the embodiment of the present application does not affect the performance of data transmission, and can control the power consumption of the terminal, thereby achieving the purpose of saving power by the terminal.
第二种生成方式：基站根据信道质量信息生成天线配置信息。The second generation method: the base station generates antenna configuration information according to the channel quality information.
信道质量信息可以用于指示传输数据的信道质量的好坏程度，终端可以向基站反馈信道质量信息。本申请实施例中，信道质量信息可以包括参考信号接收功率(Reference Signal Received Power，RSRP)和/或参考信号接收质量(Reference Signal Received Quality，RSRQ)。当信道质量信息指示传输信道的质量较好，可以减少终端的收发通道数，此时基站生成的天线配置信息指示的收发天线是数目可以较少，因为终端在较高信噪比时，接收性能会更好，所以减少收发通道数，并不会降低数据传输的性能，但是可以降低终端 的功耗。而当信道质量信息指示传输信道的质量较差，为了保证信号覆盖性能，则需要增加收发通道数，此时基站生成的天线配置信息指示的收发天线是数目可以较多。这样本申请实施例就既不影响对数据传输的性能，又能对终端的功耗进行控制，达到终端节约用电的目的。The channel quality information can be used to indicate the quality of the channel quality of the transmitted data, and the terminal can feed back the channel quality information to the base station. In the embodiments of the present application, the channel quality information may include Reference Signal Received Power (RSRP) and / or Reference Signal Received Quality (RSRQ). When the channel quality information indicates that the quality of the transmission channel is good, the number of transmitting and receiving channels of the terminal can be reduced. At this time, the number of transmitting and receiving antennas indicated by the antenna configuration information generated by the base station can be smaller, because the terminal has a higher reception performance when the signal-to-noise ratio is higher. It will be better, so reducing the number of transmit and receive channels will not reduce the performance of data transmission, but it can reduce the power consumption of the terminal. When the channel quality information indicates that the quality of the transmission channel is poor, in order to ensure the signal coverage performance, the number of transmit and receive channels needs to be increased. At this time, the number of transmit and receive antennas indicated by the antenna configuration information generated by the base station may be larger. In this way, the embodiment of the present application does not affect the performance of data transmission, and can control the power consumption of the terminal, thereby achieving the purpose of saving power by the terminal.
第三种生成方式：本申请实施例中的基站可以将第一种生成方式和第二种生成方式结合生成天线配置信息。当信道质量信息较好时，基站还可以根据业务状态信息生成天线配置信息，从而进一步既不影响终端对数据传输的性能，又能对终端的功耗进行控制，达到终端节约用电的目的。The third generation method: The base station in the embodiment of the present application may combine the first generation method and the second generation method to generate antenna configuration information. When the channel quality information is good, the base station can also generate antenna configuration information according to the service status information, so as not to further affect the performance of the terminal for data transmission, and also control the power consumption of the terminal, thereby achieving the purpose of saving power for the terminal.
具体地，基站可以在终端发送的RSRP或RSRQ超过预设阈值时，根据终端发送的业务状态信息生成天线配置信息。如果终端发送的RSRP或RSRQ超过预设阈值，则可以认为此时信道传输质量较好，那么进一步可以根据终端发送的业务状态信息生成天线配置信息，例如可以设置较少的收发天线的数目。相反，如果终端发送的RSRP或RSRQ没有超过预设阈值，则可以认为此时信道传输质量较差，那么此时基站可以保持终端目前选择的收发天线的数目。也就是本申请实施例中的基站可以在信道传输质量较好的基础上，进一步判断终端要传输的数据量的大小，确定终端要选择的收发天线的数目，从而达到既不影响终端对数据传输的性能，又能对终端的功耗进行控制，实现终端节约用电的目的。Specifically, when the RSRP or RSRQ sent by the terminal exceeds a preset threshold, the base station may generate antenna configuration information according to the service status information sent by the terminal. If the RSRP or RSRQ sent by the terminal exceeds a preset threshold, it can be considered that the channel transmission quality is good at this time, and then the antenna configuration information can be generated according to the service status information sent by the terminal, for example, a smaller number of transmitting and receiving antennas can be set. Conversely, if the RSRP or RSRQ sent by the terminal does not exceed the preset threshold, it can be considered that the channel transmission quality is poor at this time, and then the base station can maintain the number of transmitting and receiving antennas currently selected by the terminal. That is, the base station in the embodiment of the present application can further determine the amount of data to be transmitted by the terminal on the basis of good channel transmission quality, and determine the number of transmitting and receiving antennas to be selected by the terminal, so as not to affect the terminal's data transmission. Performance, and can control the power consumption of the terminal, to achieve the purpose of saving power.
第四种生成方式：基站根据终端反馈的指示生成天线配置信息对终端的功耗进行控制，达到终端节约用电的目的。The fourth generation method: The base station generates antenna configuration information according to an instruction fed back by the terminal to control the power consumption of the terminal, thereby achieving the purpose of saving power by the terminal.
本申请实施例中终端反馈的指示可以用于指示终端对功耗节省的需求。例如，终端反馈的指示可以是低功耗指示，那么就表示此时终端要满足低功耗的需求。基站接收到终端反馈的指示，根据终端反馈的指示可以生成低功耗模式天线配置信息。其中，低功耗模式天线配置信息可以用于指示包括少于2个接收天线或2个发送天线的配置，也就是终端可以选择的接收天线或者发送天线的数目较少，从而满足终端低功耗的需求。The indication fed back by the terminal in the embodiments of the present application may be used to indicate a demand for power saving of the terminal. For example, the indication fed back by the terminal may be a low power consumption indication, which means that the terminal needs to meet the demand for low power consumption at this time. The base station receives the indication fed back by the terminal, and can generate the antenna configuration information of the low power consumption mode according to the indication fed back by the terminal. Among them, the low power consumption mode antenna configuration information can be used to indicate a configuration including less than 2 receiving antennas or 2 transmitting antennas, that is, the number of receiving antennas or transmitting antennas that the terminal can select is small, thereby meeting the low power consumption of the terminal. Demand.
以上四种方式下，终端需要对应地反馈业务状态信息、信道质量信息或 者指示终端对功耗节省的需求，同时也需要监控基站指示的天线配置信息，从而根据基站指示的天线配置信息调整终端选择的收发天线的数目，或者调整相应的收发射频或者基带通道数目。这样终端不管是在数据信道还是控制信道的发送或接收，使用调整后的天线配置对应的通道数进行接收数据或者发送数据，就可以既不影响终端对数据传输的性能，又能对终端的功耗进行控制，实现终端节约用电的目的。In the above four methods, the terminal needs to correspondingly feed back service status information, channel quality information, or indicate the terminal's need for power saving. At the same time, it needs to monitor the antenna configuration information indicated by the base station, so as to adjust the terminal selection according to the antenna configuration information indicated by the base station The number of transmitting and receiving antennas, or adjust the corresponding number of transmitting and receiving radio frequency or baseband channels. In this way, regardless of whether the terminal is transmitting or receiving on the data channel or the control channel, using the adjusted number of channels corresponding to the antenna configuration to receive or send data can not affect the performance of the terminal on data transmission, but also affect the function of the terminal. Power consumption is controlled to achieve the purpose of saving power by the terminal.
本申请实施例中的基站指示终端的天线配置信息可以包括单独配置信息或联合配置信息。其中，单独配置信息为基站采用不同的信令或者采用一个信令在不同时刻分别配置接收天线和发送天线的信息。也就是基站可以采用不同的信令分别配置接收天线和发送天线的信息，或者基站也可以采用一个信令在不同时刻分别配置接收天线和发送天线的信息。联合配置信息为基站采用一个信令统一配置接收天线和发送天线的信息。The antenna configuration information of the terminal instructed by the base station in the embodiment of the present application may include individual configuration information or joint configuration information. The separate configuration information is information that the base station uses different signaling or uses a signaling to configure the receiving antenna and the transmitting antenna at different times. That is, the base station can use different signaling to configure the information of the receiving antenna and the transmitting antenna respectively, or the base station can also use a signaling to configure the information of the receiving antenna and the transmitting antenna respectively at different times. The joint configuration information is information for the base station to uniformly configure the receiving antenna and the transmitting antenna by using one signaling.
本申请实施例基站生成了天线配置信息后，在步骤S102：基站将天线配置信息指示给终端。After the base station generates the antenna configuration information in the embodiment of the present application, in step S102: the base station indicates the antenna configuration information to the terminal.
本申请实施例中的基站根据天线配置信息的不同，将天线配置信息指示给终端也有所不同，下面介绍基站如何将天线配置信息指示给终端。The base station in the embodiment of the present application indicates that the antenna configuration information is different to the terminal according to different antenna configuration information. The following describes how the base station indicates the antenna configuration information to the terminal.
第一种指示方式：The first indication:
基站可以通过半静态指示信令将天线配置信息指示给终端，其中，半静态指示例如可以包括RRC信令，这样终端接收到天线配置信息后根据天线配置信息确定收发天线的数目。The base station may indicate the antenna configuration information to the terminal through semi-static indication signaling, where the semi-static indication may include, for example, RRC signaling, so that the terminal determines the number of transmitting and receiving antennas according to the antenna configuration information after receiving the antenna configuration information.
基站也可以通过动态指示信令将天线配置信息指示给终端，其中，动态指示信令例如可以包括DCI信令，这样终端动态地接收到天线配置信息后根据天线配置信息调整收发天线的数目。The base station may also indicate the antenna configuration information to the terminal through dynamic instruction signaling. The dynamic instruction signaling may include, for example, DCI signaling, so that the terminal dynamically adjusts the number of transmitting and receiving antennas according to the antenna configuration information after receiving the antenna configuration information dynamically.
第二种指示方式：The second indication method:
基站可以通过RRC信令将指示多种发送天线和/或接收天线数目的组合的收发天线列表发送给终端，这样终端接收到天线配置信息后可以从多种发送天线和/或接收天线数目的组合的收发天线列表选择一种组合，确定为收发 天线的数目。The base station can send a list of transmitting and receiving antennas indicating the combination of multiple transmitting antennas and / or receiving antenna numbers to the terminal through RRC signaling, so that the terminal can receive multiple antennas and / or receiving antenna combinations after receiving antenna configuration information. Select a combination of the transceiver antenna list and determine the number of transceiver antennas.
具体地，基站可以提供多种天线的配置模式，不同的天线组合对应不同的配置模式。基站可以将预先配置的多种发送天线和/或接收天线数目的组合的收发天线列表都指示给终端。Specifically, the base station may provide multiple antenna configuration modes, and different antenna combinations correspond to different configuration modes. The base station may indicate to the terminal a list of transmit / receive antennas that are pre-configured with a combination of multiple transmitting antennas and / or receiving antenna numbers.
第三种指示方式：The third indication method:
基站还可以通过动态信令指示多种发送天线和/或接收天线数目的组合的收发天线列表中的一种组合给终端,其中，动态信令包括介质接入控制(medium access control，MAC)信令或下行链路控制指示(Downlink Control Indicator，DCI)信令。The base station may also indicate to the terminal one of a combination of receiving and transmitting antenna lists of multiple transmitting antennas and / or receiving antenna numbers through dynamic signaling. The dynamic signaling includes a medium access control (MAC) signal. Order or downlink control indicator (DCI) signaling.
具体地，基站可以提供多种天线的配置模式，不同的天线组合对应不同的配置模式。当基站确定终端反馈的业务状态信息指示终端要传输的数据量较小时，那么基站可以通过动态信令指示多种组合中的一种比较少的天线组合，以达到降低终端功耗的目的。或者，当基站确定终端反馈的信道质量信息指示的传输信道的质量较好时，可以减少终端的收发通道数，此时基站可以通过动态信令指示多种组合中的一种比较少的天线组合给终端。由于终端在较高信噪比时，接收性能会更好，所以减少收发通道数，并不会降低数据传输的性能，但是可以降低终端的功耗。Specifically, the base station may provide multiple antenna configuration modes, and different antenna combinations correspond to different configuration modes. When the base station determines that the service status information fed back by the terminal indicates that the amount of data to be transmitted by the terminal is small, then the base station can indicate one of a few antenna combinations among the multiple combinations through dynamic signaling to reduce the power consumption of the terminal. Or, when the base station determines that the quality of the transmission channel indicated by the channel quality information fed back by the terminal is good, the number of receiving and transmitting channels of the terminal can be reduced. At this time, the base station can indicate one of a few antenna combinations with a small number of combinations through dynamic signaling. To the terminal. Since the receiving performance will be better when the terminal has a higher signal-to-noise ratio, reducing the number of transmitting and receiving channels will not reduce the performance of data transmission, but it can reduce the power consumption of the terminal.
具体地，基站可以约定多种收发天线组合，例如发送天线数：1，2，4，8；接收天线可以是1，2，4，8。收发天线合并指示将有多种组合，见表1。基站可以通过RRC信令指示多个收发天线数目的组合，然后由动态MAC信令或者DCI信令指示其中的一种组合。终端可以根据这种组合明确使用多少个收发天线进行数据和控制信道的传输。Specifically, the base station may agree on multiple combinations of transmitting and receiving antennas, for example, the number of transmitting antennas: 1, 2, 4, 8; and the receiving antennas may be 1, 2, 4, 8, and 8. There will be multiple combinations of the receiving and transmitting antenna combination indications, as shown in Table 1. The base station may indicate a combination of the number of multiple transmit and receive antennas through RRC signaling, and then indicate one of the combinations by dynamic MAC signaling or DCI signaling. The terminal can determine how many transceiver antennas are used for data and control channel transmission according to this combination.
表1Table 1
发送天线数目Number of transmitting antennas 接收天线数目Number of receiving antennas
天线配置模式1Antenna configuration mode 1 无限制Unlimited 无限制Unlimited
天线配置模式2Antenna configuration mode 2 发送天线数为2Number of transmitting antennas is 2 接收天线数为2Number of receiving antennas is 2
天线配置模式3Antenna configuration mode 3 发送天线数为1Number of transmitting antennas is 1 接收天线数为1Number of receiving antennas is 1
本申请实施例中，基站在指示天线配置信息给终端时，需要事先对终端的反馈的业务状态信息进行判断，以便将对应的天线组合指示给终端。如果终端反馈的业务状态信息指示的是终端要传输的数据量较大，则基站可以将多种组合中的较少天线组合指示给终端。而如果终端反馈的业务状态信息指示的是终端要传输的数据量较小，则基站可以将多种组合中的更少天线组合指示给终端。例如，基站可以将单发送单接收的天线配置指示给终端。In the embodiment of the present application, when the base station instructs the antenna configuration information to the terminal, it is necessary to determine the service status information fed back by the terminal in advance, so as to indicate the corresponding antenna combination to the terminal. If the service status information fed back by the terminal indicates that the amount of data to be transmitted by the terminal is large, the base station may indicate the fewer antenna combinations of the multiple combinations to the terminal. And if the service status information fed back by the terminal indicates that the amount of data to be transmitted by the terminal is small, the base station may indicate to the terminal fewer combinations of antennas among the multiple combinations. For example, the base station may indicate the antenna configuration for single transmission and single reception to the terminal.
同样地，基站在指示天线配置信息给终端时，需要事先对终端的反馈的信道质量信息进行判断，以便将对应的天线组合指示给终端。如果终端反馈的信道质量信息指示的是传输信道质量较好，则基站可以将多种组合中的较多天线组合指示给终端，以提高数据传输的效率。而如果终端反馈的信道质量信息指示的是传输信道质量较差，则基站可以将多种组合中的较少天线组合指示给终端，以保证数据传输的性能。Similarly, when the base station indicates the antenna configuration information to the terminal, it needs to judge the channel quality information fed back by the terminal in advance, so as to indicate the corresponding antenna combination to the terminal. If the channel quality information fed back by the terminal indicates that the quality of the transmission channel is good, the base station may indicate to the terminal more antenna combinations of the multiple combinations to improve the efficiency of data transmission. If the channel quality information fed back by the terminal indicates that the quality of the transmission channel is poor, the base station may indicate to the terminal fewer combinations of antennas among the multiple combinations to ensure the performance of data transmission.
本申请实施例中的基站考虑终端要传输的数据量的大小或传输信道质量的好坏程度，通过动态信令指示天线配置信息，相较于每个发送时间间隔(Transmission Time Interval，TTI)指示天线配置信息，延时较少，效率更高。In the embodiment of the present application, the base station considers the amount of data to be transmitted by the terminal or the quality of the transmission channel quality, and indicates the antenna configuration information through dynamic signaling. Compared with each Transmission Time Interval (TTI) Antenna configuration information, less delay and higher efficiency.
第四种指示方式：The fourth indication method:
本申请实施例中的基站可以结合多输入多输出(Multiple-Input Multiple-Output，MIMO)系统对天线的配置指示将生成的天线配置信息指示给终端。The base station in the embodiment of the present application may indicate the antenna configuration information generated to the terminal in combination with a multiple-input multiple-output (MIMO) system configuration instruction for the antenna.
在MIMO的配置中，如果指示终端发送的数据流数为1，则终端最少使用单个发送天线就可以工作。同样，如果指示终端接收的数据流数为1，终端最少使用单个接收天线也可以工作。In the MIMO configuration, if the number of data streams sent by the terminal is indicated to be 1, the terminal can work with at least a single transmitting antenna. Similarly, if the number of data streams received by the terminal is indicated to be 1, the terminal can work with a minimum of a single receiving antenna.
如果CSI-RS的端口数为1，则意味着终端只支持单发送天线，此时终端和基站的通信也只有单数据流传输，因此终端的发送天线可以使用1个，接收天线可根据需要配置1个或多个。如果终端选择多个接收天线，接收性能 会更好，但是相应地功耗也会加大。因此基站可以根据终端反馈的业务状态信息或者信道质量信息，指示终端选择一个或多个接收天线。If the number of CSI-RS ports is 1, it means that the terminal supports only a single transmitting antenna. At this time, the communication between the terminal and the base station also only transmits a single data stream. Therefore, the terminal can use one transmitting antenna, and the receiving antenna can be configured as required. 1 or more. If the terminal selects multiple receiving antennas, the receiving performance will be better, but the power consumption will increase accordingly. Therefore, the base station may instruct the terminal to select one or more receiving antennas according to the service status information or channel quality information fed back by the terminal.
本申请实施例中PMI的发送配置也会影响终端的收发天线数目，例如，基站无PMI发送，此时终端可以默认使用单天线发送，对于发送和接收的数据流数也可以隐含指示终端的收发天线数，比如发送的流数和接收的流数为1，终端可以使用单发送天线或者单接收天线去完成数据传输。The sending configuration of the PMI in the embodiment of the present application also affects the number of transmitting and receiving antennas of the terminal. For example, the base station has no PMI transmission. At this time, the terminal can use a single antenna to transmit by default. The number of transmitting and receiving antennas, for example, the number of transmitted streams and the number of received streams is 1. The terminal can use a single transmitting antenna or a single receiving antenna to complete data transmission.
具体地，本申请实施例中的基站可以将多天线传输配置参数及一个DCI的信息域联合指示给终端。其中，多天线传输配置参数主要用于对终端的发送天线和收发数据流数的指示，DCI的信息域可以用于指示低功耗天线配置模式或者指示终端的接收天线数。多天线传输配置参数可以包括指示终端的收发数据流数、信道状态信息参考信号(Channel state information reference signal，CSI-RS)端口数、解调参考信号(Demodulation Reference Signal，DMRS)的端口数以及预编码矩阵指示(Precoding Matrix Indication，PMI)的发送方式中的一种或多种。Specifically, the base station in the embodiment of the present application may jointly indicate the multi-antenna transmission configuration parameter and an information domain of a DCI to the terminal. Among them, the multi-antenna transmission configuration parameter is mainly used to indicate the number of transmitting antennas and the number of received and transmitted data streams of the terminal. The DCI information field can be used to indicate the low-power antenna configuration mode or the number of receiving antennas of the terminal. Multi-antenna transmission configuration parameters may include the number of transmitted and received data streams of the terminal, the number of channel state information reference signals (CSI-RS) ports, the number of demodulation reference signals (DMRS) ports, and One or more of a sending method of a coding matrix indication (Precoding Matrix Indication, PMI).
第五种指示方式：The fifth indication method:
这种指示方式是基站将多天线传输配置参数的一种特殊组合指示信息指示给终端。和第四种方式的差异在于，使用一种多天线配置的特殊组合，而这种组合不用于常规MIMO的数据传输指示。其中，组合指示信息包括终端的收发数据流数、CSI-RS端口数、DMRS的端口数以及PMI的发送方式中的一种或多种。This indication mode is that the base station indicates a special combination of multi-antenna transmission configuration parameters to the terminal. The difference from the fourth method is that a special combination of multiple antenna configurations is used, and this combination is not used for data transmission indication of conventional MIMO. The combination instruction information includes one or more of the number of data streams transmitted and received by the terminal, the number of CSI-RS ports, the number of DMRS ports, and the PMI transmission method.
具体的，指示终端天线接收组合的信息包括：单流发送，单CSI-RS端口，PMI指示一个有效的预编码码本，这种组合是一种特殊组合，因为如果单个CSI-RS端口，则基站是单个发送天线，预编码指示是无效的，使用这种组合表示终端需要单天线接收。类似的，可以指示DMRS端口指向一个不存在或预留的RS端口数，也是一种异常的组合，作为低功耗天线配置的指示。Specifically, the information indicating the terminal antenna receiving combination includes: single stream transmission, single CSI-RS port, and PMI indicates a valid precoding codebook. This combination is a special combination because if a single CSI-RS port, The base station is a single transmitting antenna, and the precoding indication is invalid. Using this combination indicates that the terminal needs a single antenna for reception. Similarly, the DMRS port can be instructed to point to a number of RS ports that do not exist or are reserved, which is also an abnormal combination as an indication of low-power antenna configuration.
综上所述，本申请实施例考虑到终端选择收发天线的数目与功耗有关，更多的收发天线意味着功耗较大，所以本申请实施例中的基站根据业务状态 信息和/或信道质量信息，或者基站根据终端反馈的指示生成天线配置信息。也就是基站根据终端要传输的数据量的大小生成天线配置信息，如果数据量较小，那么配置的天线配置信息指示的发送天线和/或接收天线的数目较少，从而达到节约用电的效果。或者基站根据信道质量的好坏程度生成天线配置信息，如果信道质量较好，那么配置的天线配置信息指示的发送天线和/或接收天线的数目较少，从而达到节约用电的效果。或者基站根据终端反馈的对功耗节省的需求生成天线配置信息，即基站是根据终端的实际对功耗节省的需求从而生成的天线配置信息使得终端节约用电。相较于目前终端只通过周期性的监控数据信道来实现节约用电的目的，本申请实施例基站根据终端的实际传输数据量大小或者信道质量或终端对功耗节省的需求来指示终端选择收发天线数目，能够使得终端更加节约用电。In summary, the embodiment of the present application considers that the number of transmitting and receiving antennas selected by the terminal is related to power consumption. More transmitting and receiving antennas means larger power consumption, so the base station in the embodiment of the present application according to service status information and / or channels. Quality information, or the base station generates antenna configuration information according to an indication fed back by the terminal. That is, the base station generates antenna configuration information according to the amount of data to be transmitted by the terminal. If the amount of data is small, the number of transmitting antennas and / or receiving antennas indicated by the configured antenna configuration information is small, thereby achieving the effect of saving power consumption. . Or the base station generates antenna configuration information according to the quality of the channel quality. If the channel quality is good, the number of transmitting antennas and / or receiving antennas indicated by the configured antenna configuration information is small, thereby achieving the effect of saving power consumption. Or the base station generates the antenna configuration information according to the demand for power saving saved by the terminal, that is, the base station generates the antenna configuration information according to the actual demand for power saving of the terminal, so that the terminal saves power. Compared with the current terminal, which only achieves the purpose of saving power by periodically monitoring the data channel, the base station in the embodiment of the present application instructs the terminal to select the sending and receiving according to the actual amount of data transmitted by the terminal or the channel quality or the demand for power saving of the terminal. The number of antennas can make the terminal more power-efficient.
本申请实施例提供了多种基站指示天线配置信息的方式，较为灵活。其中基站通过动态信令指示天线配置信息，相较于每个发送时间间隔(Transmission Time Interval，TTI)指示天线配置信息，延时较少，效率更高。The embodiments of the present application provide multiple ways for the base station to indicate antenna configuration information, which is more flexible. The base station indicates the antenna configuration information through dynamic signaling. Compared with each transmission time interval (Transmission Time Interval, TTI) indicating the antenna configuration information, the base station has less delay and higher efficiency.
