Description
本申请涉及实施例涉及通信技术领域,尤其涉及一种通信方法和装置。The present application relates to embodiments related to the field of communication technologies, and in particular to a communication method and device.
在通信系统中,为了提高系统容量,通常采用大规模阵列天线技术。其中,在大规模阵列天线技术,天线端口数可以达到32或更多,可以极大的提高并行传输多流数据的能力。然而,由于天线端口数较多,基站的耗电量也非常大。因此,如何降低基站的耗电量,减少基站的能耗,是非常重要的问题。In the communication system, in order to increase the system capacity, the large-scale array antenna technology is usually adopted. Among them, in the large-scale array antenna technology, the number of antenna ports can reach 32 or more, which can greatly improve the ability to transmit multi-stream data in parallel. However, due to the large number of antenna ports, the power consumption of the base station is also very large. Therefore, how to reduce the power consumption of the base station and reduce the energy consumption of the base station are very important issues.
目前,通常是通过关闭部分天线端口数的方式,来降低基站的能耗。具体的,基站通过无线资源控制(Radio resource control,RRC)为终端设备配置信道状态信息参考信号(Channel state information reference signal,CSI-RS),以使终端设备根据CSI-RS进行信道状态信息(Channel state information,CSI)测量,并将测量得到的CSI信息反馈给基站,基站将根据CSI信息为终端设备分配资源。当基站通过关闭部分天线端口的方式来降低能耗时,首先将部分天线端口关闭,再根据当前处于开启状态的天线端口,通过RRC信令向终端设备发送更新的CSI-RS配置,这样,终端设备将根据更新后的CSI-RS配置重新进行CSI测量,并将测量得到的CSI信息反馈给基站。Currently, the power consumption of the base station is usually reduced by turning off some antenna ports. Specifically, the base station configures the channel state information reference signal (CSI-RS) for the terminal device through the radio resource control (Radio resource control, RRC), so that the terminal device performs the channel state information (Channel state information reference signal, CSI-RS) according to the CSI-RS. State information (CSI) is measured, and the measured CSI information is fed back to the base station, and the base station will allocate resources for the terminal device according to the CSI information. When the base station reduces energy consumption by closing some antenna ports, it first turns off some antenna ports, and then sends the updated CSI-RS configuration to the terminal device through RRC signaling according to the antenna ports that are currently open. In this way, the terminal The device will perform CSI measurement again according to the updated CSI-RS configuration, and feed back the measured CSI information to the base station.
然而,由于不同射频通道所对应的天线端口上的信道状态信息不一样,基站在通过上述方式关闭部分天线端口时,可能会造成系统容量减小,导致数据的传输速率降低,增加了传输时延。However, because the channel state information on the antenna ports corresponding to different radio frequency channels is different, when the base station closes some antenna ports in the above manner, the system capacity may be reduced, resulting in a decrease in the data transmission rate, and an increase in transmission delay. .

下面首先针对本申请实施例适用场景进行简要说明。The following first briefly describes the application scenarios of the embodiments of the present application.
在大规模阵列天线技术中,如何降低基站的耗电量,减少基站的能耗,是非常重要的问题。目前,当前多数网络设备的天线阵列为二维天线阵,即包含水平维度和垂直维度的天线阵元。天线阵元通过一定的虚拟化方式,可以实现一个阵元或多个阵元连接到一个射频通道上。假定每一个射频通道与一个天线端口对应,则每一个天线端口均可以通过行序号和列序号表示出来。图2为天线端口的二维分布示意图,如图2所示,假定天线阵元、射频通道和天线端口之间是一一映射关系,且包含的天线端口数为32,其中在单个极化方向上垂直维度有4个端口,水平维度有4个端口。由于采用双极化天线,所以总的天线端口数为4﹡4﹡2。在用RRC信令配置码本配置信息单元(Codebook Config(information element,IE))时,会明确指示单个极化方向上水平维度和垂直维度的端口数,即N1和N2的取值,如在图2中,N1和N2的取值分别为4。其中,目前的协议只支持部分N1、N2的值,部分N1、N2的值如下表1所示。在表1中P
CSI-RS为总的天线端口数,即总的CSI-RS端口数,其中,N1、N2的取值将会直接影响码本(codebook)的选择,进而影响CSI的测量准确性。
In the large-scale array antenna technology, how to reduce the power consumption of the base station and reduce the energy consumption of the base station are very important issues. At present, the antenna arrays of most current network devices are two-dimensional antenna arrays, that is, antenna array elements that include horizontal and vertical dimensions. The antenna array element can be connected to a radio frequency channel through a certain virtualization method. Assuming that each radio frequency channel corresponds to an antenna port, each antenna port can be represented by a row number and a column number. Figure 2 is a schematic diagram of the two-dimensional distribution of antenna ports. As shown in Figure 2, it is assumed that there is a one-to-one mapping relationship between antenna elements, radio frequency channels, and antenna ports, and the number of antenna ports included is 32, where in a single polarization direction There are 4 ports in the upper vertical dimension, and 4 ports in the horizontal dimension. Due to the use of dual-polarized antennas, the total number of antenna ports is 4﹡4﹡2. When RRC signaling is used to configure the Codebook Config (information element, IE), it will clearly indicate the number of horizontal and vertical ports in a single polarization direction, that is, the values of N1 and N2. In Figure 2, the values of N1 and N2 are 4 respectively. Among them, the current protocol only supports some values of N1 and N2, and some values of N1 and N2 are shown in Table 1 below. In Table 1, P CSI-RS is the total number of antenna ports, that is, the total number of CSI-RS ports. Among them, the value of N1 and N2 will directly affect the choice of codebook, and then affect the accuracy of CSI measurement Sex.
表1Table 1
可以理解的是,天线端口关闭的主要目的是减少网络设备的能耗,但在天线端口关闭时,天线端口的数量也减少,则会带来一定的容量损失。以32端口为例,当天线 端口关闭一半时,可能的关闭方式如图3a-图3d所示。在图3a中,关闭了第3行和第4行对应的天线端口,在图3b中,关闭了第2行和第4行对应的天线端口,在图3c中,关闭了第3列和第4列对应的天线端口,在图3d中,关闭了第2列和第4列对应的天线端口。It is understandable that the main purpose of closing the antenna port is to reduce the energy consumption of the network device, but when the antenna port is closed, the number of antenna ports is also reduced, which will cause a certain capacity loss. Take the 32 port as an example. When the antenna port is half closed, the possible closing methods are shown in Figure 3a-3d. In Figure 3a, the antenna ports corresponding to rows 3 and 4 are closed. In Figure 3b, the antenna ports corresponding to rows 2 and 4 are closed. In Figure 3c, the antenna ports corresponding to rows 3 and 4 are closed. The antenna ports corresponding to the 4 columns, in Figure 3d, the antenna ports corresponding to the second and fourth columns are closed.
在不同的关闭组合下,由于每个天线端口经历的信道衰落会不同,终端设备所测量得到的CSI也会有所不同。另外,水平维度和垂直维度的天线端口数会直接影响水平和垂直维度的波束宽度。比如图3a中,由于关闭了第3行和第4行对应的天线端口,因此,在垂直维度有两个天线端口,水平维度有4个天线端口,在经过预编码加权后,垂直维度的波束会比较宽,水平维度的波束会比较窄。例如,对于分布在高楼上的两个终端在进行多用户配对时,则需要较窄的垂直波束来规避干扰。对于分布在地面上具有相似下倾角的两个终端在进行多用户配对时,则需要较窄的水平波束来规避干扰。因此,在不同的天线端口关闭组合下,终端设备所测量的CSI是不同的,数据传输速度也会有所不同,网络设备最终的能耗也会有所不同。Under different closed combinations, since the channel fading experienced by each antenna port will be different, the CSI measured by the terminal device will also be different. In addition, the number of antenna ports in the horizontal and vertical dimensions will directly affect the beam width in the horizontal and vertical dimensions. For example, in Figure 3a, since the antenna ports corresponding to rows 3 and 4 are closed, there are two antenna ports in the vertical dimension and 4 antenna ports in the horizontal dimension. After precoding and weighting, the vertical dimension beam It will be wider, and the beam in the horizontal dimension will be narrower. For example, when two terminals distributed on a tall building perform multi-user pairing, a narrower vertical beam is required to avoid interference. For two terminals that are distributed on the ground and have similar downtilt angles, when multi-user pairing is performed, a narrower horizontal beam is required to avoid interference. Therefore, under different antenna port closure combinations, the CSI measured by the terminal equipment will be different, the data transmission speed will also be different, and the final energy consumption of the network equipment will also be different.
由于网络设备的业务的到达是随机的,而且不同业务的服务质量(quality of service,QoS)需求也会有所不同。因此,基站在按照上述表1中的组合关闭天线端口时,可能会造成系统容量的减小,导致数据的传输速率降低,增加传输时延。Since the arrival of the services of the network equipment is random, and the quality of service (QoS) requirements of different services will be different. Therefore, when the base station closes the antenna port according to the combination in Table 1, it may cause a decrease in system capacity, resulting in a decrease in data transmission rate and an increase in transmission delay.
本申请实施例中考虑到上述问题,提出了一种通信方法,网络设备通过向终端设备发送第一消息,该第一消息用于指示终端设备测量X个天线端口对应的信道状态信息CSI信息,并从终端设备接收第二消息,该第二消息包括Y组天线端口中至少一组天线端口对应的CSI信息,该Y组天线端口中每组天线端口所包括的天线端口数量小于或等于X,然后根据Y组天线端口中至少一组天线端口对应的CSI信息,从X个天线端口中确定关闭或开启的天线端口。由于终端设备根据第一消息测量X个天线端口对应的CSI信息后,会将X个天线端口中的Y组天线端口对应的CSI信息反馈给网络设备,网络设备将可以根据终端设备反馈的CSI信息动态的确定需要关闭或开启的天线端口,这样能够更好的匹配负载的动态变化以及业务的QoS需求,从而不仅可以减少网络设备的功耗,而且有利于减少由于关闭天线端口而带来的容量损失,提高数据的传输速率,减小数据传输时延。In the embodiments of this application, considering the above problems, a communication method is proposed. The network device sends a first message to the terminal device. The first message is used to instruct the terminal device to measure the channel state information CSI information corresponding to the X antenna ports. And receiving a second message from the terminal device, the second message including CSI information corresponding to at least one group of antenna ports in the Y group of antenna ports, and the number of antenna ports included in each group of antenna ports in the Y group of antenna ports is less than or equal to X, Then, according to the CSI information corresponding to at least one antenna port in the Y groups of antenna ports, the closed or open antenna port is determined from the X antenna ports. Since the terminal device measures the CSI information corresponding to the X antenna ports according to the first message, it will feed back the CSI information corresponding to the Y antenna ports among the X antenna ports to the network device, and the network device will be able to feed back the CSI information according to the terminal device Dynamically determine the antenna ports that need to be closed or opened, which can better match the dynamic changes of the load and the QoS requirements of the service, which not only reduces the power consumption of network equipment, but also helps reduce the capacity caused by closing the antenna port Loss, increase the data transmission rate and reduce the data transmission delay.

需要进行说明的是,若终端设备中还配置有第二配置信息时,终端设备在激活m个第一配置信息时,也可以将第二配置信息去激活。其中,将第二配置信息去激活可以理解为不使用第二配置信息。这样,终端设备将仅根据处于激活状态的第一配置信息测量X个天线端口的CSI信息。It should be noted that, if the terminal device is further configured with second configuration information, when the terminal device activates m pieces of first configuration information, the second configuration information may also be deactivated. Wherein, deactivating the second configuration information can be understood as not using the second configuration information.

In this way, the terminal device will need to send two pieces of information to the network device for the first configuration information and the second configuration information respectively.

终端设备可以通过如下几种方式确定需要测量的天线端口,以及需要关闭或开启的天线端口的第一天线端口信息:The terminal device can determine the antenna port to be measured and the first antenna port information of the antenna port to be closed or opened in the following ways:
第一种:第一消息中包括有第一配置信息的标识信息和/或需要关闭或开启的天线端口的数量。The first type: the first message includes identification information of the first configuration information and/or the number of antenna ports that need to be closed or opened.
具体的,第一消息中可以包括第一配置信息的标识信息,该第一配置信息的标识信息用于指示终端设备需要向网络设备反馈需要关闭或开启的天线端口的第一天线端口;或者,第一消息中还可以包括需要关闭或开启的天线端口的数量;或者,第一消息中也可以包括第一配置信息的标识信息和需要关闭或开启的天线端口的数量。Specifically, the first message may include identification information of the first configuration information, and the identification information of the first configuration information is used to indicate that the terminal device needs to feed back to the network device the first antenna port of the antenna port that needs to be closed or opened; or, The first message may also include the number of antenna ports that need to be closed or opened; or, the first message may also include identification information of the first configuration information and the number of antenna ports that need to be closed or opened.
其中,第一配置信息的标识信息可以定义为关闭/开启天线端口索引信息(Report Antenna PortOff Index),该第一配置信息的标识信息可以用1bit或多个比特来指示。当终端设备在第一配置信息中检测到该标识信息时,则需要在反馈的CSI内容中包括需要关闭/开启的天线端口索引,例如可以定义为天线端口索引(Antenna Port Off Index),以将确定出的需要关闭/开启的天线端口的索引反馈给网络设备。Wherein, the identification information of the first configuration information may be defined as close/open antenna port index information (Report Antenna Port Off Index), and the identification information of the first configuration information may be indicated by 1 bit or multiple bits. When the terminal device detects the identification information in the first configuration information, it needs to include the antenna port index that needs to be turned off/on in the feedback CSI content, for example, it can be defined as the antenna port index (Antenna Port Off Index) to change The index of the determined antenna port that needs to be closed/opened is fed back to the network device.
示例性的,在第一消息中包括第一配置信息的标识信息时,终端设备可以从全部天线端口中选择X个天线端口,并测量所选择的X个天线端口对应的CSI信息,从而可以确定出需要关闭或开启的天线端口的第一天线端口信息。示例性的,终端设备通过测量X个天线端口的CSI信息,从而可以确定信道的质量信息,以根据该质量信息,确定需要关闭或开启的天线端口的第一天线端口信息,其中,质量信息可以包括秩指示RI、信道质量指示(channel quality indicator;CQI)、信噪比(signal-to-noise ratio;SNR)和信干燥比(signal to interference plus noise ratio;SINR)中的至少一个。另外,X的值可以是根据经验或者实际情况取值,例如可以为16或32等,对于X的具体取值,本申请实施例在此不做限制。Exemplarily, when the first message includes the identification information of the first configuration information, the terminal device may select X antenna ports from all antenna ports, and measure the CSI information corresponding to the selected X antenna ports, so as to determine Output the first antenna port information of the antenna port that needs to be closed or opened. Exemplarily, the terminal device can determine the quality information of the channel by measuring the CSI information of X antenna ports to determine the first antenna port information of the antenna port that needs to be closed or opened according to the quality information, where the quality information may It includes at least one of rank indicator RI, channel quality indicator (CQI), signal-to-noise ratio (signal-to-noise ratio; SNR), and signal-to-interference plus noise ratio (SINR). In addition, the value of X may be a value based on experience or actual conditions, for example, it may be 16 or 32, etc. The specific value of X is not limited in the embodiment of the present application.
例如:可以测量X个天线端口后,将测量得到的RI最小的n个天线端口确定为需要关闭的天线端口,或者将得到的CQI最小的n个天线端口确定为需要关闭的天线端口,或者将测量得到的SNR或SINR最小的n个天线端口确定为需要关闭的天线端口。其中,n为预设值或者网络设备配置的值。以n为8进行说明,也即网络设备需要关闭8个天线端口来降低功耗。若总共有32个天线端口,终端设备可以根据表1中N1和N2的取值,测量32个天线端口中,关闭8个天线端口后信道的质量,从而选择RI最小的8个天线端口,或者,选择CQI最小的8个天线端口,将这8个天线端口确定为需要关闭的天线端口,并将这8个天线端口的天线端口信息确定为第一天线端口信息,或者可以选择SNR或SINR最小的8个天线端口,并将这8个天线端口确定为需要关闭的天线端口,并将这8个天线端口的天线端口信息确定为第一天线端口信息。For example: after measuring X antenna ports, the n antenna ports with the smallest measured RI can be determined as the antenna ports that need to be closed, or the n antenna ports with the smallest CQI can be determined as the antenna ports that need to be closed, or The n antenna ports with the smallest measured SNR or SINR are determined as the antenna ports that need to be closed. Among them, n is a preset value or a value configured by the network device. Let n be 8, which means that the network device needs to close 8 antenna ports to reduce power consumption. If there are a total of 32 antenna ports, the terminal device can measure the channel quality after turning off 8 antenna ports among the 32 antenna ports according to the values of N1 and N2 in Table 1, and then select the 8 antenna ports with the smallest RI, or , Select the 8 antenna ports with the smallest CQI, determine these 8 antenna ports as the antenna ports that need to be closed, and determine the antenna port information of these 8 antenna ports as the first antenna port information, or you can select the smallest SNR or SINR And determine the 8 antenna ports as the antenna ports that need to be closed, and determine the antenna port information of the 8 antenna ports as the first antenna port information.
需要进行说明的是,若第一天线端口信息为需要开启的天线端口的天线端口信息,则终端设备在确定出信道质量后,将测量得到的RI最大的m个天线端口确定为需要开启的天线端口,或者,将测量得到的CQI最大的m个天线端口确定为需要开启的天 线端口,或者将测量得到的SNR或SINR最大的m个天线端口确定为需要开启的天线端口,并将这些天线端口的天线端口信息确定为第一天线端口信息,其中,m为预设值或者网络设备配置的值。It should be noted that if the first antenna port information is the antenna port information of the antenna port that needs to be turned on, after determining the channel quality, the terminal device determines the m antenna ports with the largest measured RI as the antennas that need to be turned on Port, or determine the m antenna ports with the largest measured CQI as the antenna ports that need to be turned on, or determine the m antenna ports with the largest measured SNR or SINR as the antenna ports that need to be turned on, and use these antenna ports The antenna port information of is determined as the first antenna port information, where m is a preset value or a value configured by a network device.
示例性的,第一消息中还可以包括需要关闭或开启的天线端口的数量,其中,关闭或开启天线端口,也可以理解为关闭或开启射频通道。如可以在CSI-ReportConfig IE中采用“Nrof Antenna PortOff”字段表示,其取值为需要关闭或开启的天线端口数,其取值可以为32,24,16,12,8,4或2等。例如,如果当前总的天线端口数为32,则NrofAntennaPortOff配置为16时,表示要关闭32个天线端口中的16个天线端口。Exemplarily, the first message may also include the number of antenna ports that need to be closed or opened, where closing or opening an antenna port can also be understood as closing or opening a radio frequency channel. For example, the "Nrof Antenna PortOff" field can be used in CSI-ReportConfig IE to indicate that its value is the number of antenna ports that need to be closed or opened, and its value can be 32, 24, 16, 12, 8, 4, or 2, etc. For example, if the current total number of antenna ports is 32, when NrofAntennaPortOff is configured as 16, it means that 16 of the 32 antenna ports are to be closed.
其中,终端设备根据需要关闭或开启的天线端口的数量,对X个天线端口的CSI信息进行测量,以确定需要关闭或开启的天线端口的第一天线端口信息的方式,与上述第一消息中包括第一配置信息的标识信息时,确定第一天线端口信息的方式类似,具体可以参考上述实施例中的描述,此处不再赘述。Wherein, the terminal device measures the CSI information of the X antenna ports according to the number of antenna ports that need to be closed or opened to determine the first antenna port information of the antenna ports that need to be closed or opened, which is the same as in the above first message When the identification information of the first configuration information is included, the method for determining the first antenna port information is similar. For details, reference may be made to the description in the foregoing embodiment, which is not repeated here.
示例性的,在第一消息中包括第一配置信息的标识信息和需要关闭或开启的天线端口的数量时,终端设备将根据需要关闭或开启的天线端口的数量,对X个天线端口进行测量,从而确定出需要关闭或开启的天线端口的第一天线端口信息,并根据第一配置信息的标识信息,向网络设备反馈确定出的第一天线端口信息。其中,对于第一天线端口信息的确定方式,与前述各实施例中的确定方式类似,此处不再赘述。Exemplarily, when the identification information of the first configuration information and the number of antenna ports that need to be closed or opened are included in the first message, the terminal device will measure the X antenna ports according to the number of antenna ports that need to be closed or opened. , Thereby determining the first antenna port information of the antenna port that needs to be closed or opened, and feeding back the determined first antenna port information to the network device according to the identification information of the first configuration information. Wherein, the method for determining the first antenna port information is similar to the method for determining in the foregoing embodiments, and will not be repeated here.
在本方式中,网络设备向终端设备发送的第一消息中包括有第一配置信息的标识信息和/或需要关闭或开启的天线端口的数量,这样,终端设备将根据预设数量和/或配置的需要关闭或开启的天线端口的数量,对X个天线端口进行测量,从而确定出需要关闭和/或开启的天线端口的第一天线端口信息,从而在关闭天线端口时,有利于减小由于关闭天线端口而带来的容量损失,提高数据的传输速率,减小数据传输时延。或者在开启天线端口时,能够尽可能的提高系统容量,提高数据的传输速率。In this manner, the first message sent by the network device to the terminal device includes the identification information of the first configuration information and/or the number of antenna ports that need to be closed or opened. In this way, the terminal device will be based on the preset number and/or Configure the number of antenna ports that need to be closed or opened, and measure X antenna ports to determine the first antenna port information of the antenna ports that need to be closed and/or opened, so that when the antenna ports are closed, it is helpful to reduce The capacity loss caused by closing the antenna port increases the data transmission rate and reduces the data transmission delay. Or when opening the antenna port, the system capacity can be increased as much as possible, and the data transmission rate can be increased.
第二种:网络设备向终端设备发送第三消息,该第三消息中还可以包括至少一个天线端口信息集合,至少一个天线端口信息集合中的每个天线端口信息集合中包括至少一个第三天线端口信息,该第三消息用于指示终端设备测量每个第三天线端口对应的天线端口的CSI信息,或者,第三消息用于指示终端设备测量除第三天线端口信息对应的天线端口之外的其他天线端口的CSI信息。The second type: the network device sends a third message to the terminal device, the third message may also include at least one antenna port information set, and each antenna port information set in the at least one antenna port information set includes at least one third antenna Port information, the third message is used to instruct the terminal device to measure the CSI information of the antenna port corresponding to each third antenna port, or the third message is used to instruct the terminal device to measure the antenna port other than the antenna port corresponding to the third antenna port information CSI information of other antenna ports.
具体的,第三消息可以与第一消息为同一个消息,也可以是与第一消息不同的消息,例如第三消息可以是RRC消息。另外,天线端口信息例如可以为天线端口的索引信息。Specifically, the third message may be the same message as the first message, or may be a message different from the first message, for example, the third message may be an RRC message. In addition, the antenna port information may be index information of the antenna port, for example.
网络设备在向终端设备发送第三消息时,在第三消息中将配置至少一个天线端口信息集合,每个天线端口信息集合中包括至少一个第三天线端口信息。终端设备将测量每个天线端口信息集合中的第三天线端口信息对应的CSI信息,从而根据测量结果从至少一个第三天线端口信息中选择需要关闭或开启的天线端口。或者,终端设备将测量每个天线端口信息集合中的第三天线端口信息之外的其他天线端口信息对应的CSI信息,从而根据测量结果从至少一个第三天线端口信息中选择需要关闭或开启的天线端口。这样,由于终端设备可以根据网络设备配置的天线端口信息集合测量天线端口,由此可以减少终端设备测量天线端口的数量以及复杂度,提高终端设备的测量 效率。When the network device sends the third message to the terminal device, at least one antenna port information set is configured in the third message, and each antenna port information set includes at least one third antenna port information. The terminal device will measure the CSI information corresponding to the third antenna port information in each antenna port information set, so as to select the antenna port that needs to be closed or opened from the at least one third antenna port information according to the measurement result. Alternatively, the terminal device will measure the CSI information corresponding to other antenna port information except the third antenna port information in each antenna port information set, thereby selecting the one that needs to be turned off or turned on from at least one piece of third antenna port information according to the measurement result Antenna port. In this way, since the terminal device can measure the antenna port according to the antenna port information configured by the network device, the number and complexity of the measurement antenna port of the terminal device can be reduced and the measurement efficiency of the terminal device can be improved.
例如:第三消息中包括有3个天线端口信息集合,天线端口信息集合1中包括天线端口1、天线端口3和天线端口5,天线端口信息集合2中包括天线端口6、天线端口8和天线端口10,天线端口信息集合3中包括天线端口15、天线端口16和天线端口20。在一种实现方式中,终端设备将分别测量天线端口1、天线端口3和天线端口5对应的CSI信息,天线端口6、天线端口8和天线端口10对应的CSI信息,以及天线端口15、天线端口16和天线端口20对应的CSI信息,这样,终端设备将可以根据信道的质量信息,确定出需要关闭或开启的天线端口的第一天线端口信息,如确定出第一天线端口信息为天线端口1、天线端口3和天线端口5。其中,对于确定第一天线端口信息的方式,与前述实施例中的方式类似,此处不再赘述。For example: the third message includes 3 antenna port information sets, antenna port information set 1 includes antenna port 1, antenna port 3 and antenna port 5, and antenna port information set 2 includes antenna port 6, antenna port 8 and antenna Port 10, antenna port information set 3 includes antenna port 15, antenna port 16, and antenna port 20. In one implementation, the terminal device will measure the CSI information corresponding to antenna port 1, antenna port 3 and antenna port 5, the CSI information corresponding to antenna port 6, antenna port 8 and antenna port 10, and antenna port 15, antenna CSI information corresponding to port 16 and antenna port 20, so that the terminal device can determine the first antenna port information of the antenna port that needs to be closed or opened according to the quality information of the channel, such as determining that the first antenna port information is the antenna port 1. Antenna port 3 and antenna port 5. The method for determining the first antenna port information is similar to the method in the foregoing embodiment, and will not be repeated here.
示例性的,网络设备可以通过第三消息中的第一字段指示至少一个天线端口信息集合,其中,第一字段的比特长度可以为
比特,其中
为上取整符号,K为天线端口信息集合的数量。例如,在第三消息中指示4种天线端口关闭组合,也即第三消息中包括有4个天线端口信息集合,则K=4。其中“00”表示第一种组合,“01”表示第二种组合,“10”表示第三种组合,“11”表示第四种组合。
Exemplarily, the network device may indicate at least one set of antenna port information through the first field in the third message, where the bit length of the first field may be Bits, where Is the rounded up symbol, and K is the number of antenna port information sets. For example, if 4 antenna port closing combinations are indicated in the third message, that is, 4 antenna port information sets are included in the third message, then K=4. Among them, "00" represents the first combination, "01" represents the second combination, "10" represents the third combination, and "11" represents the fourth combination.
另外,若第三消息中仅包括一个天线端口信息集合,则终端设备将根据该天线端口信息集合中的天线端口信息,测量该些天线端口信息对应的天线端口的CSI信息,或者测量除该些天线端口信息对应的天线端口之外的其他天线端口的CSI信息。In addition, if only one antenna port information set is included in the third message, the terminal device will measure the CSI information of the antenna port corresponding to the antenna port information according to the antenna port information in the antenna port information set, or measure other CSI information of antenna ports other than the antenna port corresponding to the antenna port information.
在本方式中,由于终端设备可以根据网络设备配置的天线端口信息集合测量天线端口,由此可以减少终端设备测量天线端口的数量以及复杂度,提高终端设备的测量效率。In this manner, since the terminal device can measure the antenna port according to the antenna port information set configured by the network device, the number and complexity of the measurement antenna port of the terminal device can be reduced, and the measurement efficiency of the terminal device can be improved.
进一步地,网络设备在通过RRC消息向终端设备配置至少一个天线端口信息集合后,网络设备向终端设备发送的第一消息中还包括第四天线端口信息,该第四天线端口信息为至少一个天线端口信息集合中所包括的天线端口信息中的部分,第一消息还用于指示终端设备测量第四天线端口信息对应的天线端口的CSI信息。Further, after the network device configures at least one antenna port information set for the terminal device through the RRC message, the first message sent by the network device to the terminal device further includes fourth antenna port information, and the fourth antenna port information is at least one antenna For part of the antenna port information included in the port information set, the first message is also used to instruct the terminal device to measure the CSI information of the antenna port corresponding to the fourth antenna port information.
具体的,网络设备通过RRC消息预先为终端设备配置至少一个天线端口信息集合后,为了进一步减少终端设备测量天线端口的数量以及复杂度,提高终端设备的测量效率,网络设备还可以通过第一消息,向终端设备发送第四天线端口信息,其中,该第四天线端口信息为网络设备预先为终端设备配置的第三天线端口信息中的一部分,这样,终端设备将只需要测量第四天线端口信息对应的天线端口的CSI信息即可。Specifically, after the network device configures at least one antenna port information set for the terminal device in advance through the RRC message, in order to further reduce the number and complexity of the terminal device's measurement of antenna ports and improve the measurement efficiency of the terminal device, the network device may also send the first message , Send the fourth antenna port information to the terminal device, where the fourth antenna port information is part of the third antenna port information pre-configured by the network device for the terminal device, so that the terminal device only needs to measure the fourth antenna port information The CSI information of the corresponding antenna port is sufficient.
第三种:在网络设备为终端设备配置了至少两个第一配置信息时,网络设备可以不用向终端设备配置天线端口信息集合,此时,每一个第一配置信息均可以对应一套天线端口信息。终端设备在接收到至少两个第一配置信息后,可以根据预设的配置信息和天线端口信息之间的对应关系,确定各个第一配置信息对应的天线端口信息,从而可以测量这些天线端口信息对应的天线端口的CSI信息,或者测量除这些天线端口信息对应的天线端口之外的其他天线端口的CSI信息,以此来确定需要关闭或者开启的天线端口的第一天线端口信息。The third type: when the network device configures at least two pieces of first configuration information for the terminal device, the network device does not need to configure the antenna port information set for the terminal device. At this time, each first configuration information can correspond to a set of antenna ports information. After receiving at least two pieces of first configuration information, the terminal device can determine the antenna port information corresponding to each first configuration information according to the correspondence between the preset configuration information and the antenna port information, so that the antenna port information can be measured The CSI information of the corresponding antenna port, or the CSI information of the antenna ports other than the antenna port corresponding to the antenna port information is measured, so as to determine the first antenna port information of the antenna port that needs to be closed or opened.
由于每一个第一配置信息均可以对应一套天线端口信息,这样,终端设备在接收到至少两个第一配置信息后,可以根据预设的配置信息和天线端口信息之间的对应关 系,确定各个第一配置信息对应的天线端口信息,从而可以测量这些天线端口信息对应的天线端口的CSI信息,或者测量除这些天线端口信息对应的天线端口之外的其他天线端口的CSI信息,以此来确定需要关闭或者开启的天线端口的第一天线端口信息,由此可以降低终端设备测量天线端口的复杂度,提高终端设备的测量效率。Since each piece of first configuration information can correspond to a set of antenna port information, after receiving at least two pieces of first configuration information, the terminal device can determine according to the correspondence between the preset configuration information and antenna port information The antenna port information corresponding to each first configuration information, so that the CSI information of the antenna port corresponding to the antenna port information can be measured, or the CSI information of the antenna ports other than the antenna port corresponding to the antenna port information can be measured. The first antenna port information of the antenna port that needs to be closed or opened is determined, thereby reducing the complexity of measuring the antenna port by the terminal device and improving the measurement efficiency of the terminal device.
例如:假设终端设备激活的配置信息包括第一配置信息1、第一配置信息2和第一配置信息3。其中,第一配置信息1对应的天线端口信息包括天线端口2、天线端口4和天线端口10,第一配置信息2对应的天线端口信息包括天线端口3、天线端口6和天线端口9,第一配置信息3对应的天线端口信息包括天线端口11、天线端口15和天线端口20,终端设备通过测量天线端口2、天线端口4和天线端口10对应的CSI信息,天线端口3、天线端口6和天线端口9对应的CSI信息,以及天线端口11、天线端口15和天线端口20对应的CSI信息。这样,终端设备将可以根据信道的质量信息,确定出需要关闭或开启的天线端口的第一天线端口信息,如确定出第一天线端口信息为天线端口11、天线端口15和天线端口20。其中,对于确定第一天线端口信息的方式,与前述实施例中的方式类似,此处不再赘述。For example: suppose that the configuration information activated by the terminal device includes first configuration information 1, first configuration information 2, and first configuration information 3. The antenna port information corresponding to the first configuration information 1 includes antenna port 2, antenna port 4, and antenna port 10. The antenna port information corresponding to the first configuration information 2 includes antenna port 3, antenna port 6, and antenna port 9. The antenna port information corresponding to configuration information 3 includes antenna port 11, antenna port 15 and antenna port 20. The terminal device measures the CSI information corresponding to antenna port 2, antenna port 4 and antenna port 10, antenna port 3, antenna port 6 and antenna CSI information corresponding to port 9 and CSI information corresponding to antenna port 11, antenna port 15 and antenna port 20. In this way, the terminal device can determine the first antenna port information of the antenna port that needs to be closed or opened according to the channel quality information. For example, the first antenna port information is determined to be antenna port 11, antenna port 15, and antenna port 20. The method for determining the first antenna port information is similar to the method in the foregoing embodiment, and will not be repeated here.
值得注意的是,终端设备也可以确定至少一组天线端口,例如将天线端口11、天线端口15和天线端口20,以及天线端口3、天线端口6和天线端口9这两组天线端口的天线端口信息,确定为需要关闭或开启的天线端口的第一天线端口信息。It is worth noting that the terminal device can also determine at least one set of antenna ports, for example, the antenna ports of antenna port 11, antenna port 15 and antenna port 20, and antenna port 3, antenna port 6 and antenna port 9 The information is determined as the first antenna port information of the antenna port that needs to be closed or opened.
进一步地,终端设备在确定出需要关闭或开启的天线端口的第一天线端口信息后,可以将该第一天线端口信息携带在Y组天线端口中至少一组天线端口对应的CSI信息中进行发送,例如可以发送给网络设备。Further, after determining the first antenna port information of the antenna port that needs to be closed or opened, the terminal device may carry the first antenna port information in the CSI information corresponding to at least one antenna port among the Y groups of antenna ports for transmission , For example, can be sent to a network device.
示例性的,第一天线端口信息可以为位图信息或行列序号信息;其中,该位图信息中的每个标志位用于表示一个天线端口;该行列序号信息用于表示天线端口的行信息和列信息。Exemplarily, the first antenna port information may be bitmap information or row and column sequence number information; wherein, each flag in the bitmap information is used to indicate an antenna port; the row and column sequence number information is used to indicate the row information of the antenna port And column information.
具体的,在采用位图的指示方式表示第一天线端口信息时,由于终端设备所测量的天线端口的数量不同,因此位图中标志位的数量也有所不同,采用位图方式表示第一天线端口信息的指示方式如表2所示。Specifically, when the first antenna port information is represented by a bitmap indication method, since the number of antenna ports measured by the terminal device is different, the number of flag bits in the bitmap is also different. The bitmap method is used to represent the first antenna The indication mode of the port information is shown in Table 2.
表2Table 2
当然,也可以是‘0’表示开启天线端口,‘1’表示关闭天线端口。Of course, it can also be ‘0’ to turn on the antenna port, and ‘1’ to turn off the antenna port.
另外,对于一般的二维天线阵,可以直接指示要关闭天线端口的行、列序号。这样可以同时指示要关闭的某一行或某一列天线端口,指示的开销将会减少。如表1所示,在给定的天线端口数下,天线端口的行数或列数的集合是固定的,因此在选择需要关闭的天线端口时,不能超出所给定的行、列的范围。可以理解的是,可以按照如表3中的方式采用行列序号信息指示需要关闭的天线端口。In addition, for a general two-dimensional antenna array, you can directly indicate the row and column number of the antenna port to be closed. In this way, a certain row or column of antenna ports to be closed can be indicated at the same time, and the indicated overhead will be reduced. As shown in Table 1, under a given number of antenna ports, the number of rows or columns of antenna ports is fixed. Therefore, when selecting the antenna ports to be closed, the range of rows and columns cannot be exceeded. . It is understandable that the row and column sequence number information can be used to indicate the antenna ports that need to be closed in the manner shown in Table 3.
表3table 3
由于采用位图信息或行列序号信息表示第一天线端口信息,使得第一天线端口信息的表示方式更简单。Since the bitmap information or the row and column sequence number information is used to represent the first antenna port information, the way of representing the first antenna port information is simpler.
步骤403:终端设备向网络设备发送第二消息,该第二消息包括Y组天线端口中至少一组天线端口对应的CSI信息,该Y组天线端口中每组天线端口所包括的天线端口数量小于或等于X。Step 403: The terminal device sends a second message to the network device. The second message includes CSI information corresponding to at least one group of antenna ports in the Y group of antenna ports, and the number of antenna ports included in each group of antenna ports in the Y group of antenna ports is less than Or equal to X.
在上述步骤中,终端设备在测量了X个天线端口对应的CSI信息后,将向网络设备返回第二消息。其中,第二消息例如可以为CSI的反馈消息。In the above steps, the terminal device will return a second message to the network device after measuring the CSI information corresponding to the X antenna ports. Wherein, the second message may be, for example, a CSI feedback message.
其中,第二消息中包括Y组天线端口中至少一组天线端口对应的CSI信息,每组天线端口中均包括至少一个天线端口。例如:第二消息中包括两组天线端口中每组天线端口对应的CSI信息,分别为天线端口3、天线端口4和天线端口6对应的CSI信息,以及天线端口5、天线端口7、天线端口10、天线端口12和天线端口16对应的CSI信息。另外,第二消息中也可以仅包括一组天线端口对应的CSI信息。Wherein, the second message includes CSI information corresponding to at least one antenna port in the Y groups of antenna ports, and each group of antenna ports includes at least one antenna port. For example: the second message includes the CSI information corresponding to each of the two groups of antenna ports, namely the CSI information corresponding to antenna port 3, antenna port 4, and antenna port 6, as well as antenna port 5, antenna port 7, and antenna port. 10. CSI information corresponding to antenna port 12 and antenna port 16. In addition, the second message may also only include CSI information corresponding to a group of antenna ports.
可以理解的是,Y组天线端口中每组天线端口所包括的天线端口数量小于或等于X,也即,Y组天线端口中每组天线端口所包括的天线端口均为X个天线端口中的一部分。It can be understood that the number of antenna ports included in each group of antenna ports in the Y group of antenna ports is less than or equal to X, that is, the antenna ports included in each group of antenna ports in the Y group of antenna ports are all of the X antenna ports. Part.
步骤404:根据Y组天线端口中至少一组天线端口对应的CSI信息,从X个天线端口中确定关闭或开启的天线端口。Step 404: According to the CSI information corresponding to at least one antenna port in the Y groups of antenna ports, determine the closed or open antenna port from the X antenna ports.
在本步骤中,网络设备在接收到终端设备发送的第二消息后,可以根据该第二消息中携带的Y组天线端口中至少一组天线端口对应的CSI信息,从X个天线端口中确定关闭或开启的天线端口,其中,X和Y均为正整数。由于网络设备可以根据终端设 备反馈的CSI信息,确定需要关闭或开启的天线端口,从而有利于减少由于关闭天线端口而带来的容量损失,提高数据的传输速率,减小数据传输时延。In this step, after the network device receives the second message sent by the terminal device, it can determine from the X antenna ports according to the CSI information corresponding to at least one of the Y groups of antenna ports carried in the second message A closed or open antenna port, where X and Y are both positive integers. Since the network device can determine the antenna port that needs to be closed or opened based on the CSI information fed back by the terminal device, it is beneficial to reduce the capacity loss caused by closing the antenna port, increase the data transmission rate, and reduce the data transmission delay.
在一种可能的实现方式中,网络设备可以从Y组天线端口中的至少一组天线端口对应的CSI信息中确定目标CSI信息,并根据目标CSI信息,从X个天线端口中确定关闭或开启的天线端口。In a possible implementation manner, the network device may determine the target CSI information from the CSI information corresponding to at least one antenna port in the Y antenna ports, and determine whether to turn off or turn on the X antenna ports according to the target CSI information Antenna port.
具体的,若终端设备发送给网络设备至少两组天线端口对应的CSI信息,则网络设备将根据CSI信息确定目标CSI信息。例如:若网络设备需要关闭部分天线端口,则可以将CQI最小的CSI确定为目标CSI,若网络设备需要开启部分天线端口,则可以将CQI最大的CSI确定为目标CSI。Specifically, if the terminal device sends the CSI information corresponding to at least two sets of antenna ports to the network device, the network device will determine the target CSI information according to the CSI information. For example, if the network device needs to turn off some antenna ports, the CSI with the smallest CQI can be determined as the target CSI; if the network device needs to turn on some antenna ports, the CSI with the largest CQI can be determined as the target CSI.
可以理解的是,若终端设备发送给网络设备一组天线端口对应的CSI信息,则网络设备将这一组天线端口对应的CSI信息,确定为目标CSI。It is understandable that if the terminal device sends the CSI information corresponding to a group of antenna ports to the network device, the network device determines the CSI information corresponding to this group of antenna ports as the target CSI.
在确定出目标CSI后,将该目标CSI对应的天线端口,确定为需要关闭或开启的天线端口。After the target CSI is determined, the antenna port corresponding to the target CSI is determined as the antenna port that needs to be turned off or turned on.
在另一种可能的实现方式中,网络设备还可以从本地获取M组天线端口对应的CSI信息,并根据M组天线端口对应的CSI信息,和Y组天线端口中至少一组天线端口对应的CSI信息,确定目标CSI信息,然后根据目标CSI信息,从X个天线端口中确定关闭或开启的天线端口。In another possible implementation manner, the network device may also obtain the CSI information corresponding to the M groups of antenna ports locally, and according to the CSI information corresponding to the M groups of antenna ports, and the Y groups of antenna ports corresponding to at least one antenna port CSI information, determine the target CSI information, and then determine the closed or open antenna port from the X antenna ports according to the target CSI information.
具体的,网络设备本地会预先存储至少一组天线端口对应的CSI信息,网络设备在接收到终端设备发送的Y组天线端口中至少一组天线端口对应的CSI信息后,可以从本地存储的CSI信息和接收到的CSI信息中,确定目标CSI信息。例如:若网络设备需要关闭部分天线端口,则可以将CQI最小的CSI确定为目标CSI,若网络设备需要开启部分天线端口,则可以将CQI最大的CSI确定为目标CSI。Specifically, the network device locally pre-stores the CSI information corresponding to at least one set of antenna ports. After receiving the CSI information corresponding to at least one set of antenna ports among the Y sets of antenna ports sent by the terminal device, the network device can obtain the locally stored CSI From the information and the received CSI information, the target CSI information is determined. For example, if the network device needs to turn off some antenna ports, the CSI with the smallest CQI can be determined as the target CSI; if the network device needs to turn on some antenna ports, the CSI with the largest CQI can be determined as the target CSI.
在确定出目标CSI信息后,针对步骤402中的几种情况,网络设备将根据如下几种方式确定需要关闭或开启的天线端口:After determining the target CSI information, for the several situations in step 402, the network device will determine the antenna ports that need to be closed or opened according to the following methods:
第一种:对于第一消息中包括有第一配置信息的标识信息和/或需要关闭或开启的天线端口的数量时,终端设备在确定出需要关闭或开启的天线端口的第一天线端口信息后,会将该第一天线端口信息携带在Y组天线端口中至少一组天线端口对应的CSI信息中发送给网络设备。网络设备在确定出目标CSI信息后,可以根据该目标CSI信息中包括的天线端口的第一天线端口信息,确定需要关闭或开启的天线端口。The first type: when the first message includes the identification information of the first configuration information and/or the number of antenna ports that need to be closed or opened, the terminal device determines the first antenna port information of the antenna ports that need to be closed or opened Then, the first antenna port information will be carried in the CSI information corresponding to at least one antenna port among the Y groups of antenna ports and sent to the network device. After determining the target CSI information, the network device may determine the antenna port that needs to be closed or opened according to the first antenna port information of the antenna port included in the target CSI information.
示例性的,可以将第一天线端口信息对应的天线端口,直接确定为需要关闭或开启的天线端口,由此可以提高确定需要关闭或开启的天线端口的效率。Exemplarily, the antenna port corresponding to the first antenna port information may be directly determined as the antenna port that needs to be closed or opened, thereby improving the efficiency of determining the antenna port that needs to be closed or opened.
第二种:对于第一消息中包括至少两个天线端口信息集合,至少两个天线端口信息集合中的每个天线端口信息集合中包括至少一个天线端口的第三天线端口信息的情况,终端设备可以通过测量每个第三天线端口信息对应的天线端口的CSI信息,或者测量除第三天线端口信息对应的天线端口之外的其他端口的CSI信息,以确定需要关闭或开启的天线端口的第一天线端口信息,并将该第一天线端口信息携带在Y组天线端口中至少一组天线端口对应的CSI信息中发送给网络设备。网络设备可以根据确定出的目标CSI信息中包括的天线端口的第一天线端口信息,确定需要关闭或开启的天线端口。示例性的,可以将第一天线端口信息对应的天线端口,确定为需要关闭或开 启的天线端口。The second type: for the case where the first message includes at least two antenna port information sets, and each antenna port information set in the at least two antenna port information sets includes third antenna port information for at least one antenna port, the terminal device The CSI information of the antenna port corresponding to each third antenna port information can be measured, or the CSI information of other ports except the antenna port corresponding to the third antenna port information can be measured to determine the first antenna port that needs to be closed or opened. One antenna port information, and the first antenna port information is carried in the CSI information corresponding to at least one antenna port among the Y groups of antenna ports and sent to the network device. The network device may determine the antenna port to be closed or opened according to the first antenna port information of the antenna port included in the determined target CSI information. Exemplarily, the antenna port corresponding to the first antenna port information may be determined as the antenna port that needs to be closed or opened.
需要进行说明的是,若第一消息中包括一个天线端口信息集合,该天线端口信息集合中包括至少一个天线端口的第三天线端口信息,此时,终端设备测量第三天线端口信息对应的天线端口的CSI信息或者测量除第三天线端口信息对应的天线端口之外的其他端口的CSI信息后,可以仅将测量得到的CQI、PMI和RI发送给网络设备,网络设备可以根据第一配置信息中包括的天线端口信息集合,确定需要关闭或开启的天线端口。示例性的,网络设备可以将天线端口信息集合中包括的第三天线端口信息对应的天线端口,确定为需要关闭或开启的天线端口。It should be noted that if the first message includes an antenna port information set, the antenna port information set includes the third antenna port information of at least one antenna port, at this time, the terminal device measures the antenna corresponding to the third antenna port information After the CSI information of the port or the CSI information of other ports other than the antenna port corresponding to the third antenna port information is measured, only the measured CQI, PMI, and RI may be sent to the network device, and the network device may use the first configuration information The antenna port information collection included in the, determine the antenna port that needs to be closed or opened. Exemplarily, the network device may determine the antenna port corresponding to the third antenna port information included in the antenna port information set as the antenna port that needs to be closed or opened.
第三种:在网络设备为终端设备配置了至少两个第一配置信息时,由于每个第一配置信息均对应有一组天线端口,因此,终端设备在对天线端口进行测量后,将确定需要关闭或开启的天线端口,并根据预设的CSI信息和天线端口之间的对应关系,确定需要关闭或开启的天线端口,并将需要关闭或开启的天线端口对应的CSI信息,携带在Y组天线端口中至少一组天线端口对应的CSI信息中发送给网络设备。其中,终端设备可以向网络设备反馈至少一个CSI信息。这样,网络设备将根据CSI信息和天线端口信息之间的对应关系,确定目标CSI信息所对应的第二天线端口信息,并根据第二天线端口信息,从X个天线端口中确定关闭或开启的天线端口。The third type: when the network device configures at least two pieces of first configuration information for the terminal device, since each first configuration information corresponds to a group of antenna ports, the terminal device will determine the need after measuring the antenna ports The antenna port that needs to be closed or opened, and the corresponding relationship between the preset CSI information and the antenna port is determined to determine the antenna port that needs to be closed or opened, and the CSI information corresponding to the antenna port that needs to be closed or opened is carried in group Y The CSI information corresponding to at least one group of antenna ports in the antenna ports is sent to the network device. The terminal device can feed back at least one piece of CSI information to the network device. In this way, the network device will determine the second antenna port information corresponding to the target CSI information according to the correspondence between the CSI information and the antenna port information, and determine whether to close or open the X antenna ports according to the second antenna port information Antenna port.
可以理解的是,在实际应用中,CSI信息和第一配置信息之间存在对应关系,第一配置信息和天线端口之间存在对应关系,因此,CSI信息和天线端口之间也存在对应关系。It can be understood that in practical applications, there is a correspondence between the CSI information and the first configuration information, and there is a correspondence between the first configuration information and the antenna port. Therefore, there is also a correspondence between the CSI information and the antenna port.
例如:若第一配置信息1对应的天线端口的天线端口信息包括天线端口2、天线端口4和天线端口10,第一配置信息2对应的天线端口的天线端口信息包括天线端口3、天线端口6和天线端口9,第一配置信息3对应的天线端口的天线端口信息包括天线端口11、天线端口15和天线端口20,且终端设备确定出需要关闭或开启的天线端口的天线端口信息为天线端口11、天线端口15和天线端口20,以及天线端口3、天线端口6和天线端口9,即为第一配置信息3和第一配置信息2对应的天线端口,则终端设备可以向网络设备发送第一配置信息3对应的CSI信息以及第一配置信息2对应的CSI信息,这样,网络设备将可以根据第一配置信息3对应的CSI信息以及第一配置信息2对应的CSI信息,确定出目标CSI信息,假设确定出的目标CSI信息为第一配置信息3对应的CSI信息,则网络设备即可确定出需要关闭或开启的天线端口为天线端口11、天线端口15和天线端口20。For example: if the antenna port information of the antenna port corresponding to the first configuration information 1 includes antenna port 2, antenna port 4, and antenna port 10, the antenna port information of the antenna port corresponding to the first configuration information 2 includes antenna port 3 and antenna port 6. And antenna port 9, the antenna port information of the antenna port corresponding to the first configuration information 3 includes antenna port 11, antenna port 15, and antenna port 20, and the terminal device determines that the antenna port information of the antenna port that needs to be closed or opened is the antenna port 11. Antenna port 15 and antenna port 20, as well as antenna port 3, antenna port 6, and antenna port 9, which are the antenna ports corresponding to the first configuration information 3 and the first configuration information 2, the terminal device can send the first configuration information to the network device. A CSI information corresponding to configuration information 3 and CSI information corresponding to first configuration information 2, so that the network device can determine the target CSI according to the CSI information corresponding to the first configuration information 3 and the CSI information corresponding to the first configuration information 2. Information, assuming that the determined target CSI information is the CSI information corresponding to the first configuration information 3, the network device can determine that the antenna ports that need to be closed or opened are antenna port 11, antenna port 15 and antenna port 20.
需要进行说明的是,若第二配置信息保持激活状态,则终端设备则会根据第一配置信息测量X个天线端口对应的CSI信息,并根据第二配置信息测量全部天线端口对应的CSI信息,并通过第二消息向网络设备反馈第一配置信息对应的CSI信息,以及第二配置信息对应的CSI信息,也即X个天线端口对应的CSI信息,以及全部天线端口对应的CSI信息。在这种情况下,网络设备可以根据这两种CSI信息,确定是否需要关闭或开启部分天线端口。It should be noted that if the second configuration information remains active, the terminal device will measure the CSI information corresponding to the X antenna ports according to the first configuration information, and measure the CSI information corresponding to all antenna ports according to the second configuration information. And feedback the CSI information corresponding to the first configuration information and the CSI information corresponding to the second configuration information to the network device through the second message, that is, the CSI information corresponding to the X antenna ports and the CSI information corresponding to all antenna ports. In this case, the network device can determine whether to close or open some antenna ports based on the two types of CSI information.
示例性的,若X个天线端口对应的CSI信息中的CQI小于全部天线端口对应的CSI信息中的CQI,或者X个天线端口对应的CSI信息中的CQI小于预设值,则说明关闭部分天线端口之后,系统的容量损失较大,不足以满足当前业务的QoS需求,此 时,网络设备将确定不关闭天线端口,并继续使用第二配置信息对应的CSI信息为完成时频资源的分配、MCS的选择以及数据传输块大小选择,以利用物理下行控制信道(Physical downlink share channel,PDSCH)传输调度时确定的传输块。Exemplarily, if the CQI in the CSI information corresponding to the X antenna ports is less than the CQI in the CSI information corresponding to all antenna ports, or the CQI in the CSI information corresponding to the X antenna ports is less than the preset value, it means that some antennas are turned off After the port, the capacity loss of the system is large, which is insufficient to meet the QoS requirements of the current service. At this time, the network device will determine not to close the antenna port, and continue to use the CSI information corresponding to the second configuration information to complete the allocation of time-frequency resources, MCS selection and data transmission block size selection are used to transmit the transmission block determined during scheduling using the physical downlink share channel (PDSCH).
网络设备根据上述任意一种方式,即可确定出需要关闭或开启的天线端口,从而可以进行天线端口的关闭或开启。网络设备在关闭或开启天线端口后,将会基于新的天线端口传输物理下行共享信道(physical downlink shared channel;PDSCH)。The network device can determine the antenna port that needs to be closed or opened according to any of the above methods, so that the antenna port can be closed or opened. After the network device closes or opens the antenna port, it will transmit the physical downlink shared channel (PDSCH) based on the new antenna port.
由于终端设备在对天线端口进行测量之后,可以将测量结果反馈给网络设备,从而使网络设备可以根据测量结果确定需要关闭或开启的天线端口,由此有利于减小由于关闭天线端口而带来的容量损失,提高数据的传输速率,减小数据传输时延,或者在开启天线端口时,能够尽可能的提高系统容量,提高数据的传输速率。After the terminal device measures the antenna port, it can feed back the measurement result to the network device, so that the network device can determine the antenna port that needs to be closed or opened according to the measurement result, which is beneficial to reduce the risk of closing the antenna port. It can increase the data transmission rate and reduce the data transmission delay, or when the antenna port is turned on, the system capacity and the data transmission rate can be increased as much as possible.

The network device sends a first message to the terminal device. The first message is used to instruct the terminal device to measure the channel state information CSI information corresponding to the X antenna ports, and receive the first message from the terminal device. The second message, the second message includes the CSI information corresponding to at least one group of antenna ports in the Y group of antenna ports, the number of antenna ports included in each group of antenna ports in the Y group of antenna ports is less than or equal to X, and then according to the Y group of antenna ports The CSI information corresponding to at least one group of antenna ports in the X antenna ports is used to determine the closed or open antenna port. Since the terminal device measures the CSI information corresponding to the X antenna ports according to the first message, it will feed back the CSI information corresponding to the Y antenna ports among the X antenna ports to the network device, and the network device will be able to feed back the CSI information according to the terminal device Determine the antenna port that needs to be closed or opened, which helps reduce the capacity loss caused by closing the antenna port, increase the data transmission rate, and reduce the data transmission delay, or when the antenna port is opened, the system can be improved as much as possible Capacity, increase the data transmission rate. In addition, when the antenna port is dynamically closed, fast CSI measurement can be realized, the measurement delay is reduced, and the measurement delay is reduced. On the one hand, it can match the QoS requirements of low-latency services, and on the other hand, it can increase the transmission rate.
