The data link transmitted on the PC5 port is called sidelink (SL), and the PC5 port defines the communication protocol between the terminal device and the terminal device. . In sidelink communication, two modes of terminal equipment (mode) are defined, namely mode-1 and mode-2. The difference between them is that for terminal equipment in mode-1, resource scheduling is performed by the base station during communication; while for terminal equipment in mode-2, resource scheduling is performed by terminal equipment during communication. For example, the base station configures a resource pool in advance, and the terminal device selects resources from the resource pool when communicating.
根据前文的介绍可知,目前在Uu口,对于CSI上报的调度是由基站进行的。但是在V2X的mode-2下,基站不会直接调度终端设备。因此,目前的CSI上报方法无法适用于V2X的mode-2,对于V2X的mode-2来说,需要讨论新的CSI上报机制。According to the foregoing introduction, it can be known that currently at the Uu port, the scheduling of the CSI report is performed by the base station. But in V2X mode-2, the base station will not directly schedule terminal equipment. Therefore, the current CSI reporting method cannot be applied to V2X mode-2. For V2X mode-2, a new CSI reporting mechanism needs to be discussed.
发明内容Summary of the invention
本申请实施例提供一种发送、接收CSI、配置资源的方法及设备,用于提供一种新的传输CSI的机制。The embodiments of the present application provide a method and device for sending and receiving CSI and configuring resources, which are used to provide a new mechanism for transmitting CSI.
第一方面,提供一种发送CSI的方法,该方法包括:第一终端设备从第一资源池选择第一资源,所述第一资源池包括的资源用于发送CSI,或所述第一资源池包括的资源用于发送侧行链路数据,所述第一资源用于发送CSI;所述第一终端设备通过所述第一资源向第二终端设备发送第一CSI。In a first aspect, a method for sending CSI is provided. The method includes: a first terminal device selects a first resource from a first resource pool, and resources included in the first resource pool are used to send CSI, or the first resource The resources included in the pool are used to send side link data, and the first resource is used to send CSI; the first terminal device sends the first CSI to the second terminal device through the first resource.
该方法可由第一通信装置执行,第一通信装置可以是通信设备或能够支持通信设备实现该方法所需的功能的通信装置,例如芯片***。示例性地,所述通信设备为终端设备。示例性地,所述终端设备为第一终端设备。The method may be executed by a first communication device, and the first communication device may be a communication device or a communication device capable of supporting the communication device to implement the functions required by the method, such as a chip system. Exemplarily, the communication device is a terminal device. Exemplarily, the terminal device is a first terminal device.
在本申请实施例中,为终端设备配置了第一资源池,第一终端设备在需要发送CSI时,可从第一资源池中选择资源发送,提供了一种新的发送CSI的机制。且第一资源池可以是用于发送侧行链路数据的资源池,例如可以直接利用为终端设备配置的用于发送侧行链路数据的资源池来作为CSI的资源池,无需额外配置资源池来发送CSI,较为简单。或者,第一资源池可以是用于发送CSI的资源池,相当于为CSI专门配置了新的资源池,从而该资源池专用于发送CSI,可以尽量减少CSI和数据之间的资源选择冲突。In the embodiment of the present application, a first resource pool is configured for the terminal device. When the first terminal device needs to send CSI, it can select a resource to send from the first resource pool, which provides a new mechanism for sending CSI. And the first resource pool may be a resource pool for sending side link data. For example, the resource pool configured for terminal equipment for sending side link data may be directly used as a resource pool for CSI, without additional configuration resources. It is relatively simple to send CSI from the pool. Alternatively, the first resource pool may be a resource pool used to send CSI, which is equivalent to a new resource pool specially configured for CSI, so that the resource pool is dedicated to sending CSI, which can minimize resource selection conflicts between CSI and data.
结合第一方面,在第一方面的一种可能的实施方式中,所述第一资源池包括的资源用于发送侧行链路数据,那么所述方法还包括:所述第一终端设备从所述第一资源池中选择第三资源;另外,所述第一终端设备通过所述第一资源向第二终端设备发送第一CSI,包括:所述第一终端设备通过所述第三资源中的所述第一资源向所述第二终端设备发送所述第一CSI,所述第一终端设备通过所述第三资源中除所述第一资源之外的资源向第三终端设备发送第一侧行链路数据。With reference to the first aspect, in a possible implementation manner of the first aspect, the resources included in the first resource pool are used to send sidelink data, and the method further includes: the first terminal device slave Selecting a third resource in the first resource pool; in addition, sending the first CSI to the second terminal device by the first terminal device through the first resource includes: the first terminal device through the third resource The first resource in the CSI sends the first CSI to the second terminal device, and the first terminal device sends the CSI to the third terminal device through resources other than the first resource in the third resource The first side uplink data.
第一终端设备可以在同时需要发送数据和CSI时从第一资源池里选择资源。例如,在某个时刻,第一终端设备需要同时向第二终端设备发送第一CSI,以及向第三终端设备发送第一侧行链路数据。那么,第一终端设备可以从第一资源池里选择第三资源,通过第三资源中的第一资源向第二终端设备发送第一CSI,以及通过第三资源中的除了第一资源外的全部或部分资源向第三终端设备发送第一侧行链路数据。相当于,第一终端设备先从第一资源池里选择了第三资源,再将第三资源里的一部分资源(第一资源)用来发送第一CSI,以及将第三资源里的另一部分资源用来发送第一侧行链路数据,从而使得所选择的发送CSI的资源和发送侧行链路数据的资源不产生冲突。The first terminal device may select resources from the first resource pool when it needs to send data and CSI at the same time. For example, at a certain moment, the first terminal device needs to simultaneously send the first CSI to the second terminal device and the first side uplink data to the third terminal device. Then, the first terminal device can select the third resource from the first resource pool, send the first CSI to the second terminal device through the first resource in the third resource, and send the first CSI through the third resource except the first resource All or part of the resources send the first side link data to the third terminal device. It is equivalent to that the first terminal device first selects the third resource from the first resource pool, and then uses a part of the third resource (the first resource) to send the first CSI, and the other part of the third resource The resource is used to send the first side uplink data, so that the selected resource for sending CSI and the resource for sending side uplink data do not conflict.
结合第一方面,在第一方面的一种可能的实施方式中,所述第一资源池包括的资源为频域资源,那么所述方法还包括:所述第一终端设备接收来自所述第二终端设备的第一配置信息,所述第一配置信息用于配置反馈时间信息,所述反馈时间信息用于所述第一终端设备在所述反馈时间信息所指示的时间发送所述第一CSI。另外,所述第一终端设备通过所述第一资源向第二终端设备发送第一CSI,包括:所述第一终端设备在所述反馈时间信息所指示的时间,通过所述第一资源向所述第二终端设备发送所述第一CSI。With reference to the first aspect, in a possible implementation of the first aspect, the resources included in the first resource pool are frequency domain resources, and the method further includes: the first terminal device receives 2. The first configuration information of the terminal device, where the first configuration information is used to configure feedback time information, and the feedback time information is used by the first terminal device to send the first terminal device at the time indicated by the feedback time information. CSI. In addition, the first terminal device sending the first CSI to the second terminal device through the first resource includes: the first terminal device sends the first CSI to the second terminal device through the first resource at the time indicated by the feedback time information The second terminal device sends the first CSI.
如果第一资源池包括的资源为频域资源,那么还需要为第一CSI配置时域资源。在本申请实施例中,第二终端设备可以为第一终端设备发送的CSI配置时域资源,从而第一终端设备可以在第二终端设备所指示的时域资源上向第二终端设备发送第一CSI。如果第二终端设备是半双工的设备,那么如果第一终端设备发送CSI的时间是未知的,则第二终端设备需要空出每个可能的时间频繁地检测CSI,会影响第二终端设备发送数据的机会。由第二终端设备来配置反馈时间信息,则第一终端设备可能发送CSI的时间对于第二终端设备来说就是已知的,那么第二终端设备只需要在频率上盲检CSI即可,并不需要空出每个可能的时间频繁地检测CSI,尽量减少对于第二终端设备发送数据的机会的影响,也降低第二终端设备因为检测CSI而带来的功耗。If the resources included in the first resource pool are frequency domain resources, time domain resources also need to be configured for the first CSI. In the embodiment of the present application, the second terminal device may configure time domain resources for the CSI sent by the first terminal device, so that the first terminal device may send the first terminal device to the second terminal device on the time domain resource indicated by the second terminal device. One CSI. If the second terminal device is a half-duplex device, then if the time when the first terminal device sends CSI is unknown, the second terminal device needs to spare every possible time to frequently detect CSI, which will affect the second terminal device The opportunity to send data. The second terminal device configures the feedback time information, and the time at which the first terminal device may send CSI is known to the second terminal device. Then the second terminal device only needs to blindly detect the CSI on the frequency, and There is no need to spare every possible time to frequently detect CSI, so as to minimize the impact on the opportunity of the second terminal device to send data, and also reduce the power consumption of the second terminal device due to the detection of CSI.
结合第一方面,在第一方面的一种可能的实施方式中,所述方法还包括:所述第一终端设备接收来自所述第二终端设备或网络设备的第二资源池的信息,以用所述第二资源池 的信息所指示的第二资源池替换所述第一资源池。With reference to the first aspect, in a possible implementation manner of the first aspect, the method further includes: the first terminal device receives information from the second terminal device or the second resource pool of the network device to Replace the first resource pool with the second resource pool indicated by the information of the second resource pool.
如果出现了资源冲突的情况,例如,第一终端设备用于发送第二CSI的第四资源与其他终端设备用于发送侧行链路数据的资源产生了冲突,或者说,第一终端设备用于发送第二CSI的第四资源与其他终端设备用于发送侧行链路数据的资源是同一个资源,那么,第二终端设备或网络设备可以重新配置第一资源池,重新配置后的第一资源池称为第二资源池。通过这种方式,可以在第一资源池的信道状况不佳,或者第一资源池被其他更高优先级的数据传输占用的情况下,为CSI的发送重新配置资源池或重新选择资源,以减少冲突,提高CSI反馈的可靠性。If there is a resource conflict, for example, the fourth resource used by the first terminal device to send the second CSI conflicts with the resource used by other terminal devices to send sidelink data, or in other words, the first terminal device uses The fourth resource used to send the second CSI is the same resource used by other terminal devices to send sidelink data. Then, the second terminal device or network device can reconfigure the first resource pool, and the reconfigured first resource pool One resource pool is called the second resource pool. In this way, when the channel condition of the first resource pool is not good, or the first resource pool is occupied by other higher priority data transmissions, the resource pool can be reconfigured or resources can be reselected for CSI transmission. Reduce conflicts and improve the reliability of CSI feedback.

Among them, the resources included in the second resource pool can be dedicated to sending CSI, or the resources included in the second resource pool can be used to send side link data, but the embodiment of the application can use the resources in the second resource pool to send Send CSI.

如上介绍了本申请实施例涉及的一些概念,下面介绍本申请实施例的技术特征。Some concepts related to the embodiments of the present application are introduced as above, and the technical features of the embodiments of the present application are introduced below.
无线通信技术在过去几十年经历了飞速的发展,先后经历了基于模拟通信***的第一代无线通信***,以全球移动通信***(global system for mobile communication,GSM)为代表的第二代移动通信技术(the 2nd generation,2G)无线通信***,以宽带码分多址(wideband code division multiple access,WCDMA)为代表的第三代移动通信技术(the 3rd generation,3G)无线通信***,再到现在已经在全世界广泛商用并且取得巨大成功的LTE***移动通信技术(the 4th generation,4G)无线通信***。无线通信***支持的业务也从最初的语音、短信等,发展到现在支持无线高速数据通信。与此同时,全世界范围内的无线连接数量正在经历持续地高速增长,各种新的无线业务类型也大量涌现,例如物联网、自动驾驶等,这些都对下一代无线通信***,例如NR***,提出了更高的要求。Wireless communication technology has experienced rapid development in the past few decades. It has successively experienced the first generation of wireless communication systems based on analog communication systems, and the second generation of mobile communication systems represented by the global system for mobile communication (GSM). Communication technology (the 2nd generation, 2G) wireless communication system, the third generation mobile communication technology (the 3rd generation, 3G) wireless communication system represented by wideband code division multiple access (WCDMA), and then The LTE fourth-generation mobile communication technology (the 4th generation, 4G) wireless communication system has been widely commercialized all over the world and has achieved great success. The services supported by the wireless communication system have also evolved from the initial voice and text messages to now support wireless high-speed data communication. At the same time, the number of wireless connections around the world is experiencing continuous rapid growth, and a variety of new wireless service types are also emerging in large numbers, such as the Internet of Things, autonomous driving, etc., which are important for next-generation wireless communication systems, such as NR systems. , Put forward higher requirements.
在NR-V2X中,定义了两种空口,第一种叫Uu,在Uu口传输的数据链路被称为上行链路和下行链路,Uu口定义了终端设备和基站之间的通信协议。第二种叫PC5,在PC5口传输的数据链路被称为sidelink,PC5口定义了终端设备和终端设备之间的通信协议。In NR-V2X, two air interfaces are defined. The first is called Uu. The data link transmitted on the Uu port is called the uplink and the downlink. The Uu port defines the communication protocol between the terminal equipment and the base station. . The second type is called PC5. The data link transmitted on the PC5 port is called sidelink. The PC5 port defines the communication protocol between the terminal device and the terminal device.
Uu口定义了类似于NR***中的上下行的传输协议,在频段分配、带宽、帧结构、传输模式或信令定义等方面基本沿用NR***的上下行传输协议,并在此基础上增加了一些用于V2X的专用信令。PC5口在上述各方面则会有一些不同的设计,例如在频段方面,既可能考虑复用NR***的上行频段,也可能采用非授权频段;在帧结构和导频等方面,会考虑采用专用的帧结构和导频设计;在波束管理和多输入多输出(multiple-input multiple-output,MIMO)方面,会基于NR***的设计进行简化。The Uu port defines a transmission protocol similar to the uplink and downlink in the NR system. In terms of frequency band allocation, bandwidth, frame structure, transmission mode, or signaling definition, it basically follows the uplink and downlink transmission protocol of the NR system, and adds Some dedicated signaling for V2X. The PC5 port will have some different designs in the above aspects. For example, in terms of frequency bands, it may consider multiplexing the uplink frequency band of the NR system, or may use an unlicensed frequency band; in terms of frame structure and pilot frequency, it will consider using dedicated Frame structure and pilot design; in terms of beam management and multiple-input multiple-output (MIMO), it will be simplified based on the design of the NR system.
在sidelink通信中,规定了终端设备的两种行为模式,即mode-1和mode-2。它们之间的区别是,处于mode-1的终端设备,在通信时,资源调度由基站进行;而处于mode-2的终端设备,在通信时,资源调度由终端设备进行,例如基站可能事先配置资源池,终端设备在通信时,从该资源池中选择资源。In sidelink communication, two behavior modes of terminal equipment are specified, namely mode-1 and mode-2. The difference between them is that for terminal equipment in mode-1, resource scheduling is performed by the base station during communication; while for terminal equipment in mode-2, resource scheduling is performed by terminal equipment during communication, for example, the base station may be configured in advance Resource pool, the terminal device selects resources from the resource pool when communicating.
对于V2X通信的CSI获取,其支持信道质量信息(channel quality information,CQI)/秩指示(rank indication,RI)上报,并且CQI和RI总是被一起上报。预编码矩阵指示(precoding matrix indication,PMI)的上报在R16WI阶段不支持。对于多秩(rank)的物理侧行共享信道(physical sidelink shared channels,PSSCH)的传输,最多支持2天线端口;For V2X communication CSI acquisition, it supports channel quality information (channel quality information, CQI)/rank indication (rank indication, RI) reporting, and CQI and RI are always reported together. The reporting of precoding matrix indication (PMI) is not supported in the R16WI phase. For multi-rank physical sidelink shared channels (PSSCH) transmission, a maximum of 2 antenna ports are supported;
在侧行链路中,CSI在PSSCH中传输(包括只包含CSI的PSSCH),并使用数据传输的资源分配流程。In the side link, CSI is transmitted in the PSSCH (including the PSSCH containing only CSI), and the resource allocation process of data transmission is used.
根据上述标准,目前的RI只支持2天线端口,那么RI的比特数为1(bit)。CQI有较大概率会复用NR Uu的CQI表格,因此CQI所占比特数为4比特。因此目前CSI上报的信息比特数有以下两种情况:According to the above standards, the current RI only supports 2 antenna ports, so the number of bits of the RI is 1 (bit). There is a high probability that CQI will reuse the CQI table of NR Uu, so the number of bits occupied by CQI is 4 bits. Therefore, the current number of information bits reported by CSI has the following two situations:
如果1比特的RI表示rank=1,则需要反馈一个大小为4比特的CQI,CSI总共为5 比特;If a 1-bit RI indicates rank=1, a CQI with a size of 4 bits needs to be fed back, and the total CSI is 5 bits;
如果1比特的RI表示rank=2,则需要反馈两个大小为4比特的CQI,CSI总共为9比特。If a 1-bit RI indicates rank=2, two CQIs with a size of 4 bits need to be fed back, and the CSI is 9 bits in total.
在侧行链路上支持传输CSI-RS,CSI-RS至少可用于CQI和RI的测量。但在侧行链路上传输CSI-RS,需要受限在PSSCH的传输之内。而只有当有数据需要发送时,才会由PSSCH承载传输,所以这个规定暗示了,CSI-RS只会随数据发送,因此CSI-RS的发送可能是非周期性的。而基于非周期性的CSI-RS的测量和CSI上报,也只可能是非周期性的。Supports transmission of CSI-RS on the side link, and CSI-RS can be used for at least CQI and RI measurement. However, the transmission of CSI-RS on the side link needs to be limited to the transmission of PSSCH. And only when there is data to be sent, it will be carried by the PSSCH for transmission, so this regulation implies that CSI-RS will only be sent with the data, so the CSI-RS transmission may be aperiodic. The measurement and CSI reporting based on aperiodic CSI-RS can only be aperiodic.
在NR***中,支持终端设备向基站上报CSI。具体的,基站先确定承载参考信号的资源的信息,并向终端设备发送测量配置信息,测量配置信息包括承载参考信号的资源的信息,还可以包括用于终端设备向基站发送CSI的资源的信息,以及包括上报CSI的条件等信息。之后,基站可以向终端设备发送参考信号。终端设备接收测量配置信息后,在测量配置信息所指示的承载参考信号的资源接收参考信号,对参考信号进行测量,并在满足测量配置信息所指示的上报条件时,在测量配置信息所配置的用于发送CSI的资源,向基站发送CSI。In the NR system, terminal equipment is supported to report CSI to the base station. Specifically, the base station first determines the information of the resource carrying the reference signal, and sends measurement configuration information to the terminal device. The measurement configuration information includes information about the resource carrying the reference signal, and may also include information about the resource used by the terminal device to send CSI to the base station. , And information including the conditions for reporting CSI. After that, the base station can send the reference signal to the terminal device. After receiving the measurement configuration information, the terminal device receives the reference signal on the resource carrying the reference signal indicated by the measurement configuration information, measures the reference signal, and when the reporting condition indicated by the measurement configuration information is met, the measurement configuration information is configured Resources used to send CSI, send CSI to the base station.
可以看到,目前在NR Uu口,对于CSI上报的调度过程是由基站进行的。但是在NR-V2X的mode-2下,处于mode-2的终端设备,基站可能事先配置资源池,终端设备在通信时,从该资源池中选择资源,也就是说,在终端设备的通信过程中,基站不会直接调度终端设备。因此,目前的CSI上报方法无法适用于NR-V2X的mode-2。对于NR-V2X的mode-2来说,需要讨论CSI的新的传输机制。It can be seen that currently at the NR Uu port, the scheduling process for CSI reporting is performed by the base station. However, in mode-2 of NR-V2X, for terminal equipment in mode-2, the base station may configure a resource pool in advance. When the terminal equipment communicates, it selects resources from the resource pool, that is, in the communication process of the terminal equipment , The base station will not directly schedule terminal equipment. Therefore, the current CSI reporting method cannot be applied to mode-2 of NR-V2X. For mode-2 of NR-V2X, it is necessary to discuss the new transmission mechanism of CSI.
鉴于此,提供本申请实施例提供的方法。在本申请实施例中,为终端设备配置了第一资源池,第一终端设备在需要发送CSI时,可从第一资源池中选择资源发送,也就是说,本申请实施例提供了一种新的发送CSI的机制。且第一资源池可以是用于发送侧行链路数据的资源池,例如可以直接利用为终端设备配置的用于发送侧行链路数据的资源池来作为CSI的资源池,无需额外配置资源池来发送CSI,较为简单。或者,第一资源池可以是用于发送CSI的资源池,相当于为CSI专门配置了新的资源池,从而该资源池专用于发送CSI,可以尽量减少CSI和数据之间的资源选择冲突。In view of this, the method provided in the embodiment of the present application is provided. In the embodiment of this application, a first resource pool is configured for the terminal device. When the first terminal device needs to send CSI, it can select a resource to send from the first resource pool. That is, the embodiment of this application provides a New mechanism for sending CSI. And the first resource pool may be a resource pool for sending side link data. For example, the resource pool configured for terminal equipment for sending side link data may be directly used as a resource pool for CSI, without additional configuration resources. It is relatively simple to send CSI from the pool. Alternatively, the first resource pool may be a resource pool used to send CSI, which is equivalent to a new resource pool specially configured for CSI, so that the resource pool is dedicated to sending CSI, which can minimize resource selection conflicts between CSI and data.

Because this embodiment is applied to the network architecture shown in FIG. 2 as an example, the first terminal device described below may be the terminal device 1 in the network architecture shown in FIG. 2, and the first terminal device described below may be The second terminal device may be the terminal device 2 in the network architecture shown in FIG. 2; or, the first terminal device described below may be the terminal device 2 in the network architecture shown in FIG. The second terminal device may be the terminal device 1 in the network architecture shown in FIG. 2. In addition, the network device described in the following may be a network device in the network architecture shown in FIG. 2.
S31、第一终端设备从第一资源池选择第一资源,所述第一资源池包括的资源用于发送CSI,或所述第一资源池包括的资源用于发送侧行链路数据,所述第一资源用于发送CSI。S31. The first terminal device selects a first resource from a first resource pool, where the resources included in the first resource pool are used to send CSI, or the resources included in the first resource pool are used to send side link data, so The first resource is used to send CSI.
在S31之前,第二终端设备可以先向第一终端设备发送CSI-RS。例如,第二终端设备可以在向第二终端设备发送数据时,通过PSSCH向第一终端设备发送CSI-RS。第一终端设备接收来自第二终端设备的CSI-RS后,可以根据CSI-RS进行测量,从而可以得到CSI,例如为第一CSI。在第二终端设备向终端设备发送CSI-RS之前,第二终端设备还可以向第 一终端设备发送测量配置信息,测量配置信息可以指示承载CSI-RS的资源的信息,还可以指示第一终端设备对于CSI的发送条件等。第一终端设备接收来自第二终端设备的测量配置信息后,根据测量配置信息的指示,可以接收来自第二终端设备的CSI-RS。在根据CSI-RS进行测量,得到第一CSI后,可以在满足测量配置信息所指示的CSI的发送条件时,通过第一资源向第二终端设备发送第一CSI。第一资源就不是第二终端设备调度的,而是第一终端设备自行选择的,这种方式符合NR-V2X的mode-2的要求。Before S31, the second terminal device may first send the CSI-RS to the first terminal device. For example, the second terminal device may send a CSI-RS to the first terminal device through the PSSCH when sending data to the second terminal device. After the first terminal device receives the CSI-RS from the second terminal device, it can measure according to the CSI-RS, so that the CSI can be obtained, for example, the first CSI. Before the second terminal device sends the CSI-RS to the terminal device, the second terminal device may also send measurement configuration information to the first terminal device. The measurement configuration information may indicate the information of the resource carrying the CSI-RS, and may also indicate the first terminal The transmission conditions of the device for CSI, etc. After the first terminal device receives the measurement configuration information from the second terminal device, it can receive the CSI-RS from the second terminal device according to the indication of the measurement configuration information. After measuring according to the CSI-RS and obtaining the first CSI, the first CSI may be sent to the second terminal device through the first resource when the CSI sending condition indicated by the measurement configuration information is satisfied. The first resource is not scheduled by the second terminal device, but selected by the first terminal device. This method meets the requirements of NR-V2X mode-2.
测量配置信息可以包括如下的至少一种或它们的任意组合:测量对象,上报配置信息,测量标识,数量配置信息,测量间隔,上报资源信息,或上报方式信息。当然,除了如上的几种信息之外,测量配置信息还可以包括其他的信息,或者,测量配置信息不包括如上的几种信息,而是包括其他的信息,具体的不做限制。The measurement configuration information may include at least one of the following or any combination thereof: measurement object, report configuration information, measurement identifier, quantity configuration information, measurement interval, report resource information, or report method information. Of course, in addition to the above several kinds of information, the measurement configuration information may also include other information, or the measurement configuration information does not include the above several kinds of information, but includes other information, which is not specifically limited.
其中,测量对象可以包括一个或一组时频资源和目标小区(cell)的标识号(ID)的组合。例如一个测量对象为带宽(band1)+小区1,就表明指示第一终端设备测量band1的小区1。The measurement object may include a combination of one or a group of time-frequency resources and the identification number (ID) of the target cell (cell). For example, if a measurement object is bandwidth (band1)+cell 1, it indicates that the first terminal device is instructed to measure cell 1 of band1.
上报配置信息就是指CSI的发送条件,可以理解为,第一终端设备在向第二终端设备发送CSI时,需要满足上报配置信息对应的条件。例如,上报配置信息可以包括如下的一种或它们的任意组合:发送CSI的触发条件,所使用的参考信号,发送CSI的格式(例如每个小区或每个波束(beam)的参考信号接收功率(reference signal received power,RSRP),或CSI对应的最大的小区数量或波束的数量等)。Reporting configuration information refers to the sending condition of CSI. It can be understood that when the first terminal device sends CSI to the second terminal device, it needs to meet the condition corresponding to the reporting configuration information. For example, the reported configuration information may include one or any combination of the following: trigger conditions for sending CSI, reference signal used, format of sending CSI (for example, reference signal received power of each cell or each beam) (reference signal received power, RSRP), or the maximum number of cells or beams corresponding to CSI).
对于一个测量对象来说,第一终端设备可能只测量一次,或者也可能测量多次。如果测量了多次,且需要通过一个CSI来发送多次的测量结果,那么就可以为该测量对象添加测量标识,一个测量标识对应于一次测量结果,以区分多次的测量结果。For a measurement object, the first terminal device may only measure once, or may measure multiple times. If multiple measurements are performed and multiple measurement results need to be sent through one CSI, then a measurement identifier can be added to the measurement object, and one measurement identifier corresponds to one measurement result to distinguish multiple measurement results.
数量配置,可以理解为参数配置,是配置第一终端设备需发送的具体的参数,这些参数例如包括RSRP、CQI、RI或PMI中的至少一种,当然还可能包括其他的参数。Quantity configuration can be understood as parameter configuration, which is to configure the specific parameters that the first terminal device needs to send. These parameters include, for example, at least one of RSRP, CQI, RI, or PMI, and of course, may also include other parameters.
测量间隔,例如包括同步信号块测量时间配置信息(SS blocks measurement timing configuration,SMTC)。测量间隔主要是针对终端设备测量同步信号块(synchronous signal block,SSB)的情况,例如一般是为一个频率配置一个SMTC,SMTC可以理解为是用于测量的时间窗,一个SMTC在时域上可以包括该SMTC对应的频率下的各个小区所发送的SSB。而本申请实施例所涉及的参考信号主要是CSI-RS,因此对于测量间隔不多赘述。The measurement interval includes, for example, synchronization signal block measurement timing configuration information (SS blocks measurement timing configuration, SMTC). The measurement interval is mainly for the terminal equipment to measure the synchronous signal block (synchronous signal block, SSB). For example, one SMTC is generally configured for a frequency. SMTC can be understood as a time window for measurement. An SMTC can be used in the time domain. Including the SSB sent by each cell under the frequency corresponding to the SMTC. However, the reference signal involved in the embodiment of the present application is mainly a CSI-RS, so the measurement interval is not described in detail.
上报资源信息是指用于第一终端设备向第二终端设备发送CSI的资源的信息。例如,能够用于第一终端设备向第二终端设备发送CSI的资源可以是PSSCH资源,或者也可以是其他的资源。Reporting resource information refers to resource information used by the first terminal device to send CSI to the second terminal device. For example, the resources that can be used by the first terminal device to send CSI to the second terminal device may be PSSCH resources or other resources.
上报方式信息是指用于第一终端设备向第二终端设备发送CSI的方式的信息。例如,第一终端设备向第二终端设备发送CSI,可以是周期性发送,或者是非周期性发送,或者是半持续性发送,等等。The reporting mode information refers to information about the mode used by the first terminal device to send CSI to the second terminal device. For example, when the first terminal device sends CSI to the second terminal device, it may be sent periodically, or aperiodicly, or semi-continuously, and so on.
本申请实施例以NR-V2X的mode-2为例,因此终端设备在通过侧行链路发送数据时,需要从资源池中选择资源。在mode-2下,一般会为终端设备配置用于发送侧行链路数据的资源池,或者说,是为终端设备配置用于发送PSSCH的资源池。例如,网络设备可以通过广播的方式为终端设备配置用于发送侧行链路数据的资源池,或者用于发送侧行链路数据的资源池也可以通过协议规定,无需网络设备发送相应的信息。The embodiment of the present application takes the mode-2 of NR-V2X as an example. Therefore, the terminal device needs to select resources from the resource pool when sending data through the side link. In mode-2, the terminal device is generally configured with a resource pool for sending side uplink data, or in other words, a resource pool for sending PSSCH is configured for the terminal device. For example, a network device can configure a resource pool for sending side-link data to a terminal device in a broadcast manner, or a resource pool used to send side-link data can also be specified by an agreement, without the network device sending corresponding information .
本申请实施例提出,终端设备在通过侧行链路发送CSI时,也可以从资源池中选择资 源,例如将该资源池称为第一资源池。关于第一资源池可以有不同的实现方式,下面分别介绍。The embodiment of the present application proposes that when a terminal device sends CSI through a side link, it can also select a resource from a resource pool, for example, the resource pool is called the first resource pool. There can be different implementations of the first resource pool, which are introduced separately below.
作为第一资源池的一种可选的实施方式,第一资源池可以是用于发送侧行链路数据的资源池,或者说,第一资源池包括的资源可以用于发送侧行链路数据。因为在侧行链路上,可以将CSI作为数据看待,因此第一终端设备在发送CSI时,可以直接在用于发送侧行链路数据的资源池里选择资源。在这种方式下,无需为CSI再额外配置其他的资源池,减少了配置资源池的操作过程,即终端设备或者网络设备可以在用于传输侧行链路数据的资源池中选择资源用于传输CSI。此第一资源池可以为协议预定义的资源池,也可以是由网络设备配置的资源池。如果第一资源池包括的资源用于发送侧行链路数据,那么可以理解为,第一资源池本身是用于发送侧行链路数据的资源池,但本申请实施例可以将第一资源池进行复用,即,通过第一资源池,除了可以发送侧行链路数据之外,也可以发送CSI,当然,对于第一资源池所包括的某个资源来说,在同一个时刻,只能是用于发送侧行链路数据,或用于发送CSI,不能在同一时刻既发送侧行链路数据也发送CSI。在这种情况下,第一资源用于发送CSI(这里的CSI是第一CSI),或者理解为,第一终端设备从第一资源池选择第一资源是用来发送第一CSI的,或者说,第一终端设备在需要发送第一CSI时,从第一资源池选择了第一资源。As an optional implementation manner of the first resource pool, the first resource pool may be a resource pool used to send side link data, or in other words, the resources included in the first resource pool may be used to send side link data. data. Because on the side link, CSI can be treated as data, so when the first terminal device sends CSI, it can directly select resources in the resource pool used to send side link data. In this way, there is no need to configure additional resource pools for CSI, which reduces the operation process of configuring resource pools. That is, terminal devices or network devices can select resources from the resource pool used to transmit side link data. Transmit CSI. The first resource pool may be a resource pool predefined by the protocol, or a resource pool configured by a network device. If the resources included in the first resource pool are used to send side link data, it can be understood that the first resource pool itself is a resource pool used to send side link data, but the embodiment of the present application may use the first resource Pools are multiplexed, that is, through the first resource pool, in addition to sending side link data, CSI can also be sent. Of course, for a certain resource included in the first resource pool, at the same time, It can only be used to send side uplink data or to send CSI, and cannot send both side uplink data and CSI at the same time. In this case, the first resource is used to send CSI (here, CSI is the first CSI), or it is understood that the first terminal device selects the first resource from the first resource pool to send the first CSI, or In other words, when the first terminal device needs to send the first CSI, it selects the first resource from the first resource pool.
如果第一资源池是用于发送侧行链路数据的资源池。那么第一终端设备可以在只需要发送CSI时从第一资源池里选择资源。例如第一终端设备只需发送第一CSI,而无需发送侧行链路数据,第一终端设备从第一资源池里选择了第一资源来发送第一CSI。If the first resource pool is a resource pool for sending side link data. Then, the first terminal device may select resources from the first resource pool when it only needs to send CSI. For example, the first terminal device only needs to send the first CSI without sending the side link data, and the first terminal device selects the first resource from the first resource pool to send the first CSI.
或者,第一终端设备可以在只需要发送侧行链路数据时从第一资源池里选择资源。例如第一终端设备只需发送第一侧行链路数据,而无需发送CSI,第一终端设备从第一资源池里选择了资源来发送第一CSI。Or, the first terminal device may select a resource from the first resource pool when it only needs to send side link data. For example, the first terminal device only needs to send the first side link data without sending CSI, and the first terminal device selects resources from the first resource pool to send the first CSI.
或者,第一终端设备也可以在同时需要发送数据和CSI时从第一资源池里选择资源。例如,在某个时刻,第一终端设备需要同时向第二终端设备发送第一CSI,以及向第三终端设备发送第一侧行链路数据。那么,第一终端设备可以从第一资源池选择第一资源向第二终端设备发送第一CSI,以及从第一资源池选择除了第一资源外的其他的一个或多个资源向第三终端设备发送第一侧行链路数据;或者,第一终端设备也可以从第一资源池里选择第三资源,通过第三资源中的第一资源向第二终端设备发送第一CSI,以及通过第三资源中的除了第一资源外的全部或部分资源向第三终端设备发送第一侧行链路数据。相当于,第一终端设备先从第一资源池里选择了第三资源,再将第三资源里的一部分资源(第一资源)用来发送第一CSI,以及将第三资源里的另一部分资源用来发送第一侧行链路数据,从而使得所选择的发送CSI的资源和发送侧行链路数据的资源不产生冲突。Alternatively, the first terminal device may also select resources from the first resource pool when it needs to send data and CSI at the same time. For example, at a certain moment, the first terminal device needs to simultaneously send the first CSI to the second terminal device and the first side uplink data to the third terminal device. Then, the first terminal device may select the first resource from the first resource pool to send the first CSI to the second terminal device, and select one or more resources other than the first resource from the first resource pool to the third terminal. The device sends the first side uplink data; or, the first terminal device may also select a third resource from the first resource pool, and send the first CSI to the second terminal device through the first resource in the third resource, and through All or part of the resources in the third resource except the first resource sends the first side uplink data to the third terminal device. It is equivalent to that the first terminal device first selects the third resource from the first resource pool, and then uses a part of the third resource (the first resource) to send the first CSI, and the other part of the third resource The resource is used to send the first side uplink data, so that the selected resource for sending CSI and the resource for sending side uplink data do not conflict.
或者例如,在某个时刻,第一终端设备需要同时向第二终端设备发送第一CSI和第一侧行链路数据。那么,第一终端设备可以从第一资源池选择第一资源向第二终端设备发送第一CSI,以及从第一资源池选择除了第一资源外的其他的一个或多个资源向第二终端设备发送第一侧行链路数据;或者,第一终端设备也可以从第一资源池里选择第三资源,通过第三资源中的第一资源向第二终端设备发送第一CSI,以及通过第三资源中的除了第一资源外的全部或部分资源向第二终端设备发送第一侧行链路数据。相当于,第一终端设备先从第一资源池里选择了第三资源,再将第三资源里的一部分资源(第一资源)用来发送第一CSI,以及将第三资源里的另一部分资源用来发送第一侧行链路数据,从而使得所选 择的发送CSI的资源和发送侧行链路数据的资源不产生冲突。而第一终端设备可以向一个终端设备同时发送CSI和侧行链路数据,或者第一终端设备也可以向不同的终端设备同时发送CSI和侧行链路数据,具体的不做限制。Or for example, at a certain moment, the first terminal device needs to simultaneously send the first CSI and the first side uplink data to the second terminal device. Then, the first terminal device can select the first resource from the first resource pool to send the first CSI to the second terminal device, and select one or more resources other than the first resource from the first resource pool to the second terminal. The device sends the first side uplink data; or, the first terminal device may also select a third resource from the first resource pool, and send the first CSI to the second terminal device through the first resource in the third resource, and through All or part of the resources in the third resource except the first resource sends the first side uplink data to the second terminal device. It is equivalent to that the first terminal device first selects the third resource from the first resource pool, and then uses a part of the third resource (the first resource) to send the first CSI, and the other part of the third resource The resource is used to send the first side uplink data, so that the selected resource for sending CSI and the resource for sending side uplink data do not conflict. The first terminal device may simultaneously send CSI and sidelink data to one terminal device, or the first terminal device may also simultaneously send CSI and sidelink data to different terminal devices, which is not specifically limited.
如果将用于发送侧行链路数据的资源池作为第一资源池,那么第一资源池包括的就是时频资源,因此第一终端设备在第一资源池里选择资源,选择的就是时频资源,因此也无需再额外配置用于发送CSI的时域资源。If the resource pool used to send side link data is used as the first resource pool, then the first resource pool includes time-frequency resources. Therefore, the first terminal device selects resources in the first resource pool, and the time-frequency resource is selected. Therefore, there is no need to configure additional time domain resources for sending CSI.
或者,作为第一资源池的另一种可选的实施方式,第一资源池也可以是用于发送CSI的资源池,或者说,第一资源池包括的资源用于发送CSI。可以理解为,除了用于发送侧行链路数据的资源池之外,还额外为终端设备配置了专用于发送CSI的第一资源池,此第一资源池可以为协议预定义的资源池,也可以是由网络设备配置的资源池。从而终端设备在发送侧行链路数据时可以从用于发送侧行链路数据的资源池里选择资源,而在发送CSI时可以从第一资源池里选择资源,这样有助于减少在选择发送数据的资源和发送CSI的资源时的碰撞。如果第一资源池包括的资源用于发送CSI,那么第一资源池所包括的第一资源也就用于发送CSI。Or, as another optional implementation manner of the first resource pool, the first resource pool may also be a resource pool used to send CSI, or in other words, resources included in the first resource pool are used to send CSI. It can be understood that, in addition to the resource pool used to send side link data, the terminal device is additionally configured with a first resource pool dedicated to sending CSI. This first resource pool may be a resource pool predefined by the protocol, or It can be a resource pool configured by a network device. Therefore, the terminal device can select resources from the resource pool used to send side uplink data when sending side uplink data, and can select resources from the first resource pool when sending CSI, which helps to reduce The collision between the resource for sending data and the resource for sending CSI. If the resources included in the first resource pool are used to send CSI, then the first resources included in the first resource pool are also used to send CSI.
其中,第一资源池可以是用于发送侧行链路数据的资源池的子集。Wherein, the first resource pool may be a subset of the resource pool used to send side link data.
或者,第一资源池与用于发送侧行链路数据的资源池可以存在交集,但是不完全相同。例如,第一资源池和用于发送侧行链路数据的资源池都包括资源1,而第一资源池包括资源2,用于发送侧行链路数据的资源池不包括资源2;或者,第一资源池和用于发送侧行链路数据的资源池都包括资源1,而第一资源池不包括资源3,用于发送侧行链路数据的资源池包括资源3;或者,第一资源池和用于发送侧行链路数据的资源池都包括资源1,第一资源池包括资源2,用于发送侧行链路数据的资源池不包括资源2,以及第一资源池不包括资源3,用于发送侧行链路数据的资源池包括资源3。Alternatively, the first resource pool and the resource pool used for sending side link data may have an intersection, but they are not completely the same. For example, the first resource pool and the resource pool for sending side link data both include resource 1, and the first resource pool includes resource 2, and the resource pool for sending side link data does not include resource 2; or, Both the first resource pool and the resource pool for sending side link data include resource 1, but the first resource pool does not include resource 3, and the resource pool for sending side link data includes resource 3; or, first Both the resource pool and the resource pool for sending side link data include resource 1, the first resource pool includes resource 2, the resource pool for sending side link data does not include resource 2, and the first resource pool does not include Resource 3. The resource pool used for sending side link data includes resource 3.
或者,第一资源池和用于发送侧行链路数据的资源池也可以不存在交集,是两个完全不同的资源池。Or, the first resource pool and the resource pool used for sending side link data may not have an intersection, and they are two completely different resource pools.
具体的,对于第一资源池和用于发送侧行链路数据的资源池之间的关系不做限制。Specifically, there is no restriction on the relationship between the first resource pool and the resource pool used to send side link data.
如果第一资源池是用于发送侧行链路数据的资源池,那么第一资源池可以是以小区为粒度配置的,也就是说,是为一个小区配置一个第一资源池,那么该小区的所有终端设备在需要发送CSI时都可以从第一资源池里选择资源。例如该第一资源池可以是网络设备通过发送广播消息配置的,广播消息例如为***消息,或者也可以是其他消息。或者该资源池也可以是通过协议配置的,具体的不做限制。If the first resource pool is a resource pool used to send side link data, then the first resource pool may be configured with cell granularity, that is, a first resource pool is configured for a cell, then the cell All terminal devices in the CSI can select resources from the first resource pool when they need to send CSI. For example, the first resource pool may be configured by a network device by sending a broadcast message. The broadcast message is, for example, a system message, or may also be other messages. Or, the resource pool can also be configured through a protocol, and there is no specific limitation.
或者,如果第一资源池是专用于发送CSI的资源池,则第一资源池例如也可以是以小区为粒度配置的,也就是说,可以为一个小区配置一个第一资源池,那么该小区的所有终端设备在需要发送CSI时都可以从第一资源池里选择资源。例如该第一资源池可以是网络设备通过发送广播消息配置的,广播消息例如为***消息,或者也可以是其他消息。通过网络设备配置第一资源池,可以较为灵活,例如网络设备在不同的情况下配置的第一资源池可以是不同的。或者该资源池也可以是通过协议配置的,例如协议配置,无论是处于网络设备的覆盖范围之内还是处于网络设备的覆盖范围之外的终端设备,只要是处于NR-V2X的mode-2,则都可以使用该第一资源池;或者协议配置,对于处于网络设备的覆盖范围内的终端设备,如果处于NR-V2X的mode-2,就可以使用资源池1,而对于未处于网络设备的覆盖范围内的终端设备,如果处于NR-V2X的mode-2,就可以使用资源池2, 那么终端设备如果处于网络设备的覆盖范围内,且处于NR-V2X的mode-2,就可以确定资源池1为第一资源池,而终端设备如果未处于网络设备的覆盖范围内,且处于NR-V2X的mode-2,就可以确定资源池2为第一资源池。通过协议规定第一资源池,从而无需网络设备再通知第一资源池的信息,有助于节省信令开销。Or, if the first resource pool is a resource pool dedicated to sending CSI, the first resource pool may also be configured with cell granularity, for example, that is, a first resource pool may be configured for a cell, then the cell All terminal devices in the CSI can select resources from the first resource pool when they need to send CSI. For example, the first resource pool may be configured by a network device by sending a broadcast message. The broadcast message is, for example, a system message, or may also be other messages. The configuration of the first resource pool by the network device may be more flexible. For example, the first resource pool configured by the network device may be different in different situations. Or the resource pool can also be configured through a protocol, such as protocol configuration, whether it is a terminal device within or outside the coverage of a network device, as long as it is in mode-2 of NR-V2X, You can use the first resource pool; or protocol configuration. For terminal devices within the coverage of network devices, if they are in mode-2 of NR-V2X, resource pool 1 can be used, and for those not in network devices If the terminal device in the coverage area is in mode-2 of NR-V2X, resource pool 2 can be used. If the terminal device is in the coverage area of the network device and is in mode-2 of NR-V2X, the resource can be determined Pool 1 is the first resource pool, and if the terminal device is not within the coverage of the network device and is in mode-2 of NR-V2X, it can be determined that resource pool 2 is the first resource pool. The first resource pool is specified through the protocol, so that the network device does not need to notify the information of the first resource pool again, which helps to save signaling overhead.
如果第一资源池是专用于发送CSI的资源池,那么第一资源池所包括的可以只是频域资源,而不包括时域资源,也就是说,第一资源池是频域资源池。在这种情况下,终端设备从第一资源池里只是可以选择频域资源。而要发送CSI,还需要时域资源,那么第二终端设备可以为第一终端设备配置时域资源,第二终端设备就是第一终端设备所要发送的CSI的接收设备。例如,第二终端设备向第一终端设备发送第一配置信息,第一配置信息可以用于配置反馈时间信息,第一终端设备就可以在反馈时间信息所指示的时间发送CSI。例如,第二终端设备可以通过侧行链路控制信息(sidelink control information,SCI)向第一终端设备发送反馈时间信息,或者也可以通过PC5口向第一终端设备发送RRC消息,以将反馈时间信息发送给第一终端设备。其中,第一配置信息可以用于配置多个反馈时间信息,例如一个反馈时间信息指示一个时间,如果第一配置信息配置了多个反馈时间信息,那么第一终端设备在发送CSI时,可以从多个反馈时间信息里选择一个反馈时间信息,并在所选择的反馈时间信息所指示的时间发送CSI。If the first resource pool is a resource pool dedicated to sending CSI, then the first resource pool may include only frequency domain resources and not time domain resources, that is, the first resource pool is a frequency domain resource pool. In this case, the terminal device can only select frequency domain resources from the first resource pool. To send CSI, time domain resources are also required, so the second terminal device can configure time domain resources for the first terminal device, and the second terminal device is the receiving device of the CSI to be sent by the first terminal device. For example, the second terminal device sends the first configuration information to the first terminal device, and the first configuration information can be used to configure the feedback time information, and the first terminal device can send the CSI at the time indicated by the feedback time information. For example, the second terminal device may send feedback time information to the first terminal device through sidelink control information (SCI), or may also send an RRC message to the first terminal device through the PC5 port to change the feedback time The information is sent to the first terminal device. Wherein, the first configuration information can be used to configure multiple feedback time information, for example, one feedback time information indicates a time. If multiple feedback time information is configured in the first configuration information, then the first terminal device can send CSI from One feedback time information is selected from the multiple feedback time information, and the CSI is sent at the time indicated by the selected feedback time information.
如果第二终端设备是半双工的设备,那么如果第一终端设备发送CSI的时间是未知的,则第二终端设备需要空出每个可能的时间频繁地检测CSI,会影响第二终端设备发送数据的机会。由第二终端设备来配置反馈时间信息,则第一终端设备可能发送CSI的时间对于第二终端设备来说就是已知的,那么第二终端设备只需要在频率上盲检CSI即可,并不需要空出每个可能的时间频繁地检测CSI,尽量减少对于第二终端设备发送数据的机会的影响,也降低第二终端设备因为检测CSI而带来的功耗。If the second terminal device is a half-duplex device, then if the time when the first terminal device sends CSI is unknown, the second terminal device needs to spare every possible time to frequently detect CSI, which will affect the second terminal device The opportunity to send data. The second terminal device configures the feedback time information, and the time at which the first terminal device may send CSI is known to the second terminal device. Then the second terminal device only needs to blindly detect the CSI on the frequency, and There is no need to spare every possible time to frequently detect CSI, so as to minimize the impact on the opportunity of the second terminal device to send data, and also reduce the power consumption of the second terminal device due to the detection of CSI.
或者,如果第一资源池是专用于发送CSI的资源池,那么第一资源池包括的也可以是时频资源,这样第一终端设备在需要发送CSI时,从第一资源池选择的资源就是时频资源,而无需再通过其他方式确定时域资源,这种方式较为简单。Or, if the first resource pool is a resource pool dedicated to sending CSI, then the first resource pool may also include time-frequency resources, so that when the first terminal device needs to send CSI, the resource selected from the first resource pool is Time-frequency resources, without the need to determine time-domain resources in other ways, this method is relatively simple.
S32、第二终端设备确定所述第一资源池,所述第一资源池包括的资源用于发送CSI,或所述第一资源池包括的资源用于发送侧行链路数据。S32. The second terminal device determines the first resource pool, and the resources included in the first resource pool are used to send CSI, or the resources included in the first resource pool are used to send side link data.
第二终端设备是第一终端设备所发送的CSI的接收端。第二终端设备要接收来自第一终端设备的CSI,需要先确定第一资源池,从而可以在第一资源池所指示的资源进行检测。The second terminal device is the receiving end of the CSI sent by the first terminal device. To receive the CSI from the first terminal device, the second terminal device needs to first determine the first resource pool, so that detection can be performed on the resources indicated by the first resource pool.
S33、第一终端设备通过第一资源向第二终端设备发送第一CSI,第二终端设备在所述第一资源池所指示的资源进行检测,并通过第一资源池包括的所述第一资源接收来自第一终端设备的所述第一CSI。S33. The first terminal device sends the first CSI to the second terminal device through the first resource, and the second terminal device performs detection on the resource indicated by the first resource pool, and passes the first resource included in the first resource pool. The resource receives the first CSI from the first terminal device.
其中,第一终端设备通过第一资源向第二终端设备发送第一CSI的步骤,和S32,可以同时发生,或者第一终端设备通过第一资源向第二终端设备发送第一CSI的步骤可以发生在S32之前,或者第一终端设备通过第一资源向第二终端设备发送第一CSI的步骤可以发生在S32之后。但第二终端设备在第一资源池所指示的资源进行检测,并通过第一资源池包括的第一资源接收来自第一终端设备的第一CSI的步骤,应该是发生在S32之后。Wherein, the step of sending the first CSI to the second terminal device by the first terminal device through the first resource may occur simultaneously with S32, or the step of sending the first CSI to the second terminal device by the first terminal device through the first resource may be It occurs before S32, or the step of sending the first CSI to the second terminal device through the first resource by the first terminal device may occur after S32. However, the step of detecting the resources indicated by the first resource pool by the second terminal device and receiving the first CSI from the first terminal device through the first resource included in the first resource pool should occur after S32.
例如将第一终端设备在第一资源池中选择的资源称为第一资源,那么第一终端设备可以通过第一资源来发送第一CSI。在本申请实施例中,第一CSI可以包括CQI和RI,在未来的技术里还可能包PMI,当然还可能包括一些其他的信息,具体的不做限制。For example, the resource selected by the first terminal device in the first resource pool is called the first resource, and the first terminal device may send the first CSI through the first resource. In the embodiment of the present application, the first CSI may include CQI and RI, and may also include PMI in future technologies, and of course, may also include some other information, which is not specifically limited.
根据前文的介绍可知,第一资源池所包括的资源可以是时频资源,那么第一资源也就是时频资源;或者,第一资源池也可以只包括频域资源,那么第一资源也就只是频域资源。如果第一资源是频域资源,则第二终端设备通过第一配置信息还可以指示反馈时间信息,在这种情况下,第一终端设备可以在反馈时间信息所指示的时间,通过第一资源向第二终端设备发送第一CSI。According to the above introduction, the resources included in the first resource pool can be time-frequency resources, and the first resource is also time-frequency resources; or, the first resource pool can also only include frequency-domain resources, so the first resource is also Only frequency domain resources. If the first resource is a frequency domain resource, the second terminal device can also indicate the feedback time information through the first configuration information. In this case, the first terminal device can pass the first resource at the time indicated by the feedback time information. Send the first CSI to the second terminal device.
在本申请实施例中,为终端设备配置了第一资源池,第一终端设备在需要发送CSI时,可从第一资源池中选择资源发送,也就是说,本申请实施例提供了一种新的发送CSI的机制。且第一资源池可以是用于发送侧行链路数据的资源池,例如可以直接利用为终端设备配置的用于发送侧行链路数据的资源池来作为CSI的资源池,无需额外配置资源池来发送CSI,较为简单。或者,第一资源池可以是用于发送CSI的资源池,相当于为CSI专门配置了新的资源池,从而该资源池专用于发送CSI,可以尽量减少CSI和数据之间的资源选择冲突。In the embodiment of this application, a first resource pool is configured for the terminal device. When the first terminal device needs to send CSI, it can select a resource to send from the first resource pool. That is, the embodiment of this application provides a New mechanism for sending CSI. And the first resource pool may be a resource pool for sending side link data. For example, the resource pool configured for terminal equipment for sending side link data may be directly used as a resource pool for CSI, without additional configuration resources. It is relatively simple to send CSI from the pool. Alternatively, the first resource pool may be a resource pool used to send CSI, which is equivalent to a new resource pool specially configured for CSI, so that the resource pool is dedicated to sending CSI, which can minimize resource selection conflicts between CSI and data.
在前文介绍了,第一资源池可以就是用于发送侧行链路数据的资源池,或者第一资源池虽然是用于发送CSI的资源池,但是第一资源池可以是用于发送侧行链路数据的资源池的子集,或者第一资源池与用于发送侧行链路数据的资源池可以有交集。而第一资源池可以是以小区为粒度配置的,同样的,用于发送侧行链路数据的资源池也是以小区为粒度配置的,那么就有多个终端设备会在第一资源池里选资源,也会有多个终端设备会在用于发送侧行链路数据的资源池里选资源。那么,可能有终端设备1从第一资源池里选择了资源1用于发送CSI,有终端设备2从用于发送侧行链路数据的资源池里也选择了资源1用于发送侧行链路数据,这样就产生了冲突。在资源产生冲突的情况下,可能导致CSI发送失败或质量较差;或,导致侧行链路数据发送失败或质量较差;或,导致CSI发送失败或质量较差,以及导致侧行链路数据发送失败或质量较差。因此在本申请实施例中,也可以进一步解决资源冲突的问题。As described above, the first resource pool may be the resource pool used to send side link data, or although the first resource pool is the resource pool used to send CSI, the first resource pool may be used to send side link data. A subset of the resource pool of the link data, or the first resource pool and the resource pool used to send the side link data may have an intersection. The first resource pool can be configured at the granularity of the cell. Similarly, the resource pool used to send side link data is also configured at the granularity of the cell, so there are multiple terminal devices in the first resource pool. When selecting resources, multiple terminal devices will also select resources in the resource pool used to send sidelink data. Then, there may be terminal device 1 that selects resource 1 from the first resource pool to send CSI, and some terminal device 2 also selects resource 1 from the resource pool for sending side link data for sending side link data. Road data, so conflicts arise. In the case of resource conflicts, it may cause CSI transmission failure or poor quality; or, cause side link data transmission failure or poor quality; or, cause CSI transmission failure or poor quality, and cause side link The data transmission failed or the quality is poor. Therefore, in the embodiment of the present application, the problem of resource conflict can also be further resolved.
例如,作为CSI的接收端的第二终端设备可以判定是否出现了资源冲突的现象。例如,第一资源池包括时频资源,则第二终端设备可以对第一资源池包括的时频资源进行盲检,从而通过相应的资源接收来自第一终端设备的CSI,例如可以通过第四资源接收来自第一终端设备的第二CSI;或者,第一资源池只包括频域资源,而第二终端设备还额外配置了反馈时间信息,则第二终端设备只需在反馈时间信息所指示的时间检测第一资源池包括的频域资源,就可以通过第四资源接收来自第一终端设备的第二CSI。如果第二终端设备对于第二CSI检测失败,例如未接收第二CSI,或者第二终端设备所接收的第二CSI的质量较差,那么第二终端设备可以确定出现了资源冲突的情况,也就是说,可以确定第一终端设备用于发送第二CSI的第四资源与其他终端设备用于发送侧行链路数据的资源产生了冲突,或者说,可以确定第一终端设备用于发送第二CSI的第四资源与其他终端设备用于发送侧行链路数据的资源是同一个资源。在本申请实施例中,第二CSI可以包括CQI和RI,在未来的技术里还可能包PMI,当然还可能包括一些其他的信息,具体的不做限制。For example, the second terminal device, which is the receiving end of the CSI, can determine whether there is a resource conflict phenomenon. For example, if the first resource pool includes time-frequency resources, the second terminal device may perform blind detection on the time-frequency resources included in the first resource pool, so as to receive the CSI from the first terminal device through the corresponding resources, for example, through the fourth The resource receives the second CSI from the first terminal device; or, if the first resource pool only includes frequency domain resources, and the second terminal device is additionally configured with feedback time information, the second terminal device only needs to indicate the feedback time information The frequency domain resources included in the first resource pool are detected at the time, and the second CSI from the first terminal device can be received through the fourth resource. If the second terminal device fails to detect the second CSI, for example, it does not receive the second CSI, or the quality of the second CSI received by the second terminal device is poor, the second terminal device can determine that a resource conflict has occurred, and In other words, it can be determined that the fourth resource used by the first terminal device to send the second CSI conflicts with the resources used by other terminal devices to send side link data, or it can be determined that the first terminal device is used to send the second CSI. The fourth resource of the second CSI is the same resource used by other terminal devices to send side link data. In the embodiment of the present application, the second CSI may include CQI and RI, and may also include PMI in future technologies, and of course, may also include some other information, which is not specifically limited.
在第二终端设备确定产生了资源冲突的情况下,第二终端设备可以确定用于替换第一资源池的第二资源池,或者,第二终端设备也可以确定用于替换第四资源的第二资源。关于如何确定用于替换第一资源池的第二资源池,或确定用于替换第四资源的第二资源,第二终端设备可以有不同的方式。In the case that the second terminal device determines that a resource conflict occurs, the second terminal device may determine the second resource pool used to replace the first resource pool, or the second terminal device may also determine the second resource pool used to replace the fourth resource. Two resources. Regarding how to determine the second resource pool used to replace the first resource pool, or determine the second resource used to replace the fourth resource, the second terminal device may have different ways.
1、第二终端设备的第一种确定方式。1. The first way to determine the second terminal device.
第二终端设备可以向网络设备发送第一消息,第一消息可以用于指示第一终端设备在第一资源池选择的资源与其他终端设备所选择的资源冲突。或者,第一消息也可以只是触发消息,例如第一消息只占用1比特,如果第二终端设备向网络设备发送了第一消息,第一消息就用于触发网络设备重新配置第一资源池,或者第一消息用于触发网络设备重新选择用于发送CSI的资源。如果第一消息是触发消息,那么第一消息究竟是用于触发网络设备重新配置第一资源池,还是用于触发网络设备重新选择用于发送CSI的资源,可以通过协议规定,或者第一终端设备和第二终端设备在建立连接时会通过高层信令(例如无线资源控制(radio resource control,RRC)信令)进行握手等过程,第一消息所触发的内容也可以通过第一终端设备和第二终端设备之间的握手等过程确定。The second terminal device may send a first message to the network device, and the first message may be used to indicate that the resource selected by the first terminal device in the first resource pool conflicts with the resource selected by other terminal devices. Alternatively, the first message may also be just a trigger message. For example, the first message only occupies 1 bit. If the second terminal device sends the first message to the network device, the first message is used to trigger the network device to reconfigure the first resource pool. Or the first message is used to trigger the network device to reselect resources for sending CSI. If the first message is a trigger message, whether the first message is used to trigger the network device to reconfigure the first resource pool or to trigger the network device to reselect the resource for sending CSI can be specified by the protocol, or the first terminal When the device and the second terminal device establish a connection, they will perform a handshake process through high-level signaling (such as radio resource control (RRC) signaling), and the content triggered by the first message can also pass through the first terminal device and The process such as the handshake between the second terminal device is determined.
网络设备接收第一消息后,如果第一消息是指示第一终端设备在第一资源池选择的资源与其他终端设备所选择的资源冲突,则网络设备可以重新配置第一资源池,配置后的第一资源池可以称为第二资源池。第二资源池的实现方式可以有多种,例如网络设备所配置的第二资源池所包括的资源与第一资源池所包括的资源可以完全不同,也就是说第一资源池和第二资源池可以没有交集;或者网络设备可以向第一资源池内添加一些资源,得到第二资源池,等等。通过重新配置第一资源池,使得第一终端设备在发送CSI时可以继续从第二资源池内选择资源,对于第一终端设备来说自主性较强。且网络设备可以对终端设备的CSI的发送过程进行干预,可以根据网络拥塞状况重新配置第一资源池,从而达到优化资源配置的作用。After the network device receives the first message, if the first message indicates that the resource selected by the first terminal device in the first resource pool conflicts with the resource selected by other terminal devices, the network device can reconfigure the first resource pool. The first resource pool may be referred to as the second resource pool. The second resource pool can be implemented in multiple ways. For example, the resources included in the second resource pool configured by the network device can be completely different from the resources included in the first resource pool, that is, the first resource pool and the second resource The pools may have no intersection; or the network device may add some resources to the first resource pool to obtain the second resource pool, and so on. By reconfiguring the first resource pool, the first terminal device can continue to select resources from the second resource pool when sending CSI, which is more autonomous for the first terminal device. In addition, the network device can intervene in the sending process of the CSI of the terminal device, and can reconfigure the first resource pool according to the network congestion status, thereby achieving the effect of optimizing resource configuration.
或者,网络设备接收第一消息后,如果第一消息是指示第一终端设备在第一资源池选择的资源与其他终端设备所选择的资源冲突,则网络设备也可以重新选择资源,重新选择的资源可以称为第二资源。相当于,网络设备可以直接为第一终端设备选择第二资源,则第一终端设备直接通过第二资源向第二终端设备发送第二CSI即可,无需第一终端设备再自行选择资源,对于第一终端设备来说实现方式较为简单。Alternatively, after the network device receives the first message, if the first message indicates that the resource selected by the first terminal device in the first resource pool conflicts with the resource selected by other terminal devices, the network device may also reselect the resource and reselect it The resource can be referred to as a second resource. Equivalently, the network device can directly select the second resource for the first terminal device, and the first terminal device can directly send the second CSI to the second terminal device through the second resource, and the first terminal device does not need to select the resource by itself. For the first terminal device, the implementation is relatively simple.
如果第一消息是指示第一终端设备在第一资源池选择的资源与其他终端设备所选择的资源冲突,则网络设备究竟是重新配置第一资源池,还是直接为第一终端设备重新选择资源,可以通过协议规定,或者网络设备可以预先通知终端设备等。If the first message indicates that the resource selected by the first terminal device in the first resource pool conflicts with the resource selected by other terminal devices, does the network device reconfigure the first resource pool or directly reselect resources for the first terminal device , Can be stipulated by agreement, or network equipment can notify terminal equipment in advance.
或者,网络设备接收第一消息后,如果第一消息是触发网络设备重新配置第一资源池,那么网络设备可以根据第一消息的触发来重新配置第一资源池,配置后的第一资源池可以称为第二资源池。同样的,网络设备的配置过程可以有多种,可以参考前文的介绍。Alternatively, after the network device receives the first message, if the first message triggers the network device to reconfigure the first resource pool, the network device may reconfigure the first resource pool according to the trigger of the first message, and the configured first resource pool It can be called the second resource pool. Similarly, there can be multiple configuration processes for network devices, and you can refer to the previous introduction.
或者,网络设备接收第一消息后,如果第一消息是触发网络设备重新选择用于发送CSI的资源,则网络设备可以根据第一消息的触发来重新选择资源,重新选择的资源可以称为第二资源。Or, after the network device receives the first message, if the first message triggers the network device to reselect the resource for sending CSI, the network device may reselect the resource based on the trigger of the first message, and the reselected resource may be called the first message. Two resources.
在后面的这两种方式下,网络设备根据第一消息的触发就可以进行相应的操作,由于第一消息的结构较为简单(例如可能只占用1比特),因此网络设备无需对第一消息进行过多的解析等处理,对于网络设备来说较为简单。In the latter two methods, the network device can perform corresponding operations based on the trigger of the first message. Since the structure of the first message is relatively simple (for example, it may only occupy 1 bit), the network device does not need to perform the first message. Too much analysis and other processing is relatively simple for network equipment.
如果网络设备是重新配置了第一资源池,也就是说是得到了第二资源池,那么网络设备可以将第二资源池的信息发送给第一终端设备和第二终端设备,从而第一终端设备和第二终端设备都可以接收来自网络设备的第二资源池的信息,则第一终端设备和第二终端设备也就确定了第二资源池,且无需第一终端设备和第二终端设备之间再进行过多的交互。这样,第二终端设备也就确定了第二资源池。或者,网络设备也可以只将第二资源池的信 息发送给第二终端设备,这样第二终端设备在接收来自网络设备的第二资源池的信息后就可以确定第二资源池,再由第二终端设备将第二资源池的信息发送给第一终端设备,第二终端设备在接收来自第二终端设备的第二资源池的信息后就可以确定第二资源池,从而减少终端设备和网络设备之间的交互。If the network device reconfigures the first resource pool, that is to say, obtains the second resource pool, the network device can send the information of the second resource pool to the first terminal device and the second terminal device, so that the first terminal Both the device and the second terminal device can receive information from the second resource pool of the network device, the first terminal device and the second terminal device also determine the second resource pool, and the first terminal device and the second terminal device are not required Too much interaction between. In this way, the second terminal device also determines the second resource pool. Alternatively, the network device may only send the information of the second resource pool to the second terminal device, so that the second terminal device can determine the second resource pool after receiving the information of the second resource pool from the network device, and then the second terminal device The second terminal device sends the information of the second resource pool to the first terminal device. The second terminal device can determine the second resource pool after receiving the information of the second resource pool from the second terminal device, thereby reducing the number of terminal devices and network Interaction between devices.
同样的,如果网络设备是选择了第二资源,那么网络设备也是可以将第二资源的信息发送给第一终端设备和第二终端设备,从而第一终端设备和第二终端设备都可以接收来自网络设备的第二资源的信息,这样第一终端设备和第二终端设备就确定了第二资源;或者,网络设备可以只将第二资源的信息发送给第二终端设备,第二终端设备在接收来自网络设备的第二资源的信息后就可以确定第二资源,再由第二终端设备将第二资源的信息发送给第一终端设备,第一终端设备在接收来自第二终端设备的第二资源的信息后就可以确定第二资源。Similarly, if the network device selects the second resource, the network device can also send information about the second resource to the first terminal device and the second terminal device, so that both the first terminal device and the second terminal device can receive information from Information about the second resource of the network device, so that the first terminal device and the second terminal device determine the second resource; or, the network device may only send the information about the second resource to the second terminal device, and the second terminal device is in After receiving the second resource information from the network device, the second resource can be determined, and the second terminal device sends the second resource information to the first terminal device. The first terminal device is receiving the second resource from the second terminal device. After the information of the second resource, the second resource can be determined.
在第二终端设备的第一种确定方式下,第二终端设备是通过网络设备来确定第二资源池或第二资源,这种方式对于第二终端设备来说,只需接收来自网络设备的结果(第二资源池或第二资源)即可,无需进行过多的配置等操作,实现较为简单。这种方式比较适合于第二终端设备处于网络设备的覆盖下的场景,如果第二终端设备未处于网络设备的覆盖下,则第二终端设备可能无法与网络设备通信,从而也就无法通过网络设备来确定第二资源池或第二资源。而且第二终端设备处于网络设备的覆盖下的这种场景中,网络设备具有与第二终端设备通信的能力,因此网络设备可以利用这种能力,对用于发送CSI的资源池进行一定程度的控制,例如,第一资源池的信道状况不佳,或者第一资源池被其他更高优先级的数据传输占用时,网络设备可以为CSI的发送重新配置资源池或重新选择资源,以减少冲突,提高CSI反馈的可靠性。In the first determining method of the second terminal device, the second terminal device determines the second resource pool or the second resource through the network device. In this way, the second terminal device only needs to receive information from the network device. The result (the second resource pool or the second resource) is sufficient, and there is no need to perform excessive configuration and other operations, and the implementation is relatively simple. This method is more suitable for scenarios where the second terminal device is under the coverage of the network device. If the second terminal device is not under the coverage of the network device, the second terminal device may not be able to communicate with the network device and thus cannot pass through the network. The device determines the second resource pool or the second resource. Moreover, in this scenario where the second terminal device is under the coverage of the network device, the network device has the ability to communicate with the second terminal device, so the network device can use this ability to perform a certain degree of resource pooling for sending CSI. Control, for example, when the channel condition of the first resource pool is not good, or the first resource pool is occupied by other higher priority data transmission, the network device can reconfigure the resource pool or reselect resources for CSI transmission to reduce conflicts , Improve the reliability of CSI feedback.
同时,这种方式也可以适用于第二终端设备和第一终端设备处于不同的网络设备的覆盖下的场景,此场景下第二终端设备和第一终端设备可以利用双方所共知的资源池传输CSI。当然,如果将这种方式用于第二终端设备和第一终端设备处于不同的网络设备的覆盖下的场景,那么网络设备可以将第二资源池的信息或第二资源的信息发送给第二终端设备,再由第二终端设备将所接收的第二资源池的信息或第二资源的信息发送给第一终端设备。且此时,所述的网络设备是指覆盖第二终端设备的网络设备。At the same time, this method can also be applied to scenarios where the second terminal device and the first terminal device are under the coverage of different network devices. In this scenario, the second terminal device and the first terminal device can use a resource pool known to both parties. Transmit CSI. Of course, if this method is used in a scenario where the second terminal device and the first terminal device are under the coverage of different network devices, then the network device can send the second resource pool information or the second resource information to the second For the terminal device, the second terminal device sends the received information about the second resource pool or the second resource information to the first terminal device. And at this time, the network device mentioned refers to a network device covering the second terminal device.
而至于网络设备究竟是将第二资源池或第二资源发送给第二终端设备,还是发送给第二终端设备和第一终端设备,可以与第一终端设备是否处于网络设备的覆盖下有关。例如,第一终端设备也处于网络设备的覆盖下,则网络设备可以将第二资源池或第二资源发送给第一终端设备和第二终端设备,而无需两个终端设备之间再转发;或者,第一终端设备未处于网络设备覆盖下,那么网络设备可以只将第二资源池或第二资源发送给第二终端设备,再由第二终端设备发送给第一终端设备。当然,即使第一终端设备也处于网络设备的覆盖下,网络设备也可以只将第二资源池或第二资源发送给第二终端设备,再由第二终端设备发送给第一终端设备,具体的不做限制。As for whether the network device sends the second resource pool or the second resource to the second terminal device or to the second terminal device and the first terminal device, it may be related to whether the first terminal device is under the coverage of the network device. For example, if the first terminal device is also under the coverage of the network device, the network device can send the second resource pool or the second resource to the first terminal device and the second terminal device without forwarding between the two terminal devices; Or, if the first terminal device is not under the coverage of the network device, the network device may only send the second resource pool or the second resource to the second terminal device, and then the second terminal device sends it to the first terminal device. Of course, even if the first terminal device is also under the coverage of the network device, the network device can only send the second resource pool or the second resource to the second terminal device, and then the second terminal device sends it to the first terminal device. Specifically, There are no restrictions.
2、第二终端设备的第二种确定方式。2. The second determination method of the second terminal device.
第二终端设备无需借助于网络设备,而是可以自行配置。例如第二终端设备可以重新配置第一资源池,配置后的第一资源池可以称为第二资源池。第二资源池的实现方式可以有多种,例如第二终端设备所配置的第二资源池所包括的资源与第一资源池所包括的资源可以完全不同,也就是说第一资源池和第二资源池可以没有交集;或者第二终端设备可以 向第一资源池内添加一些资源,得到第二资源池,等等。通过重新配置第一资源池,使得第一终端设备在发送CSI时可以继续从第二资源池内选择资源,对于第一终端设备来说自主性较强。且网络设备可以不干预终端设备的CSI的发送过程,这也能提高终端设备的自主性。The second terminal device does not need to rely on network equipment, but can be configured by itself. For example, the second terminal device may reconfigure the first resource pool, and the configured first resource pool may be referred to as the second resource pool. The second resource pool can be implemented in multiple ways. For example, the resources included in the second resource pool configured by the second terminal device can be completely different from the resources included in the first resource pool, that is, the first resource pool and the second resource pool The two resource pools may have no intersection; or the second terminal device may add some resources to the first resource pool to obtain the second resource pool, and so on. By reconfiguring the first resource pool, the first terminal device can continue to select resources from the second resource pool when sending CSI, which is more autonomous for the first terminal device. In addition, the network device may not interfere with the CSI sending process of the terminal device, which can also improve the autonomy of the terminal device.
或者,第二终端设备也可以不必重新配置第一资源池,而是重新选择资源,重新选择的资源可以称为第二资源。相当于,第二终端设备可以直接为第一终端设备选择第二资源,则第一终端设备直接通过第二资源向第二终端设备发送第二CSI即可,无需第一终端设备再自行选择资源,对于第一终端设备来说实现方式较为简单。Alternatively, the second terminal device does not need to reconfigure the first resource pool, but reselects the resource, and the reselected resource may be called the second resource. Equivalently, the second terminal device can directly select the second resource for the first terminal device, and the first terminal device can directly send the second CSI to the second terminal device through the second resource, without the first terminal device selecting the resource by itself , The implementation is relatively simple for the first terminal device.
第二终端设备究竟是重新配置第一资源池,还是直接为第一终端设备重新选择资源,可以通过协议规定,或者网络设备可以预先通知终端设备等。Whether the second terminal device reconfigures the first resource pool or directly reselects resources for the first terminal device can be stipulated by a protocol, or the network device can notify the terminal device in advance.
如果第二终端设备得到的是第二资源池,则第二终端设备可以将第二资源池的信息发送给第一终端设备,则第一终端设备可以接收来自第二终端设备的第二资源池的信息,从而第一终端设备可以确定第二资源池,以能够在第二资源池内选择资源发送第二CSI;或者,如果第二终端设备得到的是第二资源,则第二终端设备可以将第二资源的信息发送给第一终端设备,则第一终端设备可以接收来自第二终端设备的第二资源的信息,从而第一终端设备可以确定第二资源,以通过第二资源发送第二CSI。If the second terminal device obtains the second resource pool, the second terminal device can send the information of the second resource pool to the first terminal device, and the first terminal device can receive the second resource pool from the second terminal device Information, so that the first terminal device can determine the second resource pool to be able to select resources in the second resource pool to send the second CSI; or, if the second terminal device obtains the second resource, the second terminal device can When the information of the second resource is sent to the first terminal device, the first terminal device can receive the information of the second resource from the second terminal device, so that the first terminal device can determine the second resource to send the second resource through the second resource. CSI.
在第二终端设备的第二种确定方式下,第二终端设备是自行确定第二资源池或第二资源,无需网络设备的干预,这种方式对于第二终端设备来说自主性较高,对于侧行链路的通信过程的控制作用更强。这种方式比较适合于第二终端设备未处于网络设备的覆盖下的场景,如果第二终端设备未处于网络设备的覆盖下,则第二终端设备可能无法与网络设备通信,从而也就无法通过网络设备来确定第二资源池或第二资源,因此第二终端设备可以自行确定第二资源池或第二资源。当然,即使第二终端设备处于网络设备的覆盖下,也可以使用第二种确定方式来确定第二资源池或第二资源。In the second determining method of the second terminal device, the second terminal device determines the second resource pool or the second resource by itself without the intervention of the network device. This method is more autonomous for the second terminal device. It has a stronger control effect on the communication process of the side link. This method is more suitable for scenarios where the second terminal device is not under the coverage of the network device. If the second terminal device is not under the coverage of the network device, the second terminal device may not be able to communicate with the network device and thus cannot pass through The network device determines the second resource pool or the second resource, so the second terminal device can determine the second resource pool or the second resource by itself. Of course, even if the second terminal device is under the coverage of the network device, the second determination method may be used to determine the second resource pool or the second resource.
无论第二终端设备使用如上的哪种确定方式,第一终端设备和第二终端设备都可以获得第二资源池的信息,或者都可以获得第二资源的信息。那么,第一终端设备如果获取的是第二资源池的信息,则第一终端设备可以在第二资源池重新选择资源来发送第二CSI,相当于,之前发送的第二CSI由于产生了资源冲突的情况,所以第二终端设备可能接收失败或者接收质量较差,因此第一终端设备可以重新选择资源,再重新发送第二CSI。例如第一终端设备从第二资源池中选择了第二资源,以通过第二资源发送第二CSI。而第二终端设备获得的也是第二资源池的信息,第二终端设备可以在第二资源池所指示的资源进行检测,并通过第二资源池包括的第二资源接收来自第二终端设备的第二CSI。No matter which of the above determination methods is used by the second terminal device, both the first terminal device and the second terminal device can obtain the information of the second resource pool, or both can obtain the information of the second resource. Then, if the first terminal device acquires the information of the second resource pool, the first terminal device can reselect resources in the second resource pool to send the second CSI, which is equivalent to that the previously sent second CSI generates resources In the case of conflict, the second terminal device may fail to receive or the reception quality is poor. Therefore, the first terminal device may reselect resources and then resend the second CSI. For example, the first terminal device selects the second resource from the second resource pool to send the second CSI through the second resource. The second terminal device also obtains information about the second resource pool. The second terminal device can perform detection on the resources indicated by the second resource pool, and receive the information from the second terminal device through the second resource included in the second resource pool. The second CSI.
或者,第一终端设备如果获取的是第二资源的信息,则第一终端设备可以直接通过第二资源重新向第二终端设备发送第二CSI。第二终端设备获取的也是第二资源的信息,则第二终端设备可以通过第二资源接收来自第一终端设备的第二CSI。Alternatively, if the first terminal device acquires the information of the second resource, the first terminal device may directly re-send the second CSI to the second terminal device through the second resource. The second terminal device also acquires the information of the second resource, and the second terminal device may receive the second CSI from the first terminal device through the second resource.
在本申请实施例中,为终端设备配置了第一资源池,第一终端设备在需要发送CSI时,可从第一资源池中选择资源发送,提供了一种新的发送CSI的机制。且第一资源池可以是用于发送侧行链路数据的资源池,例如可以直接利用为终端设备配置的用于发送侧行链路数据的资源池来作为CSI的资源池,无需额外配置资源池来发送CSI,较为简单。或者,第一资源池可以是用于发送CSI的资源池,相当于为CSI专门配置了新的资源池,从而该资源池专用于发送CSI,可以尽量减少CSI和数据之间的资源选择冲突。而且在出现资源 冲突的情况时,既可以重配置第一资源池,以优化资源池的配置,或者也可以只是重新为第一终端设备选择资源,而无需重新配置第一资源池,实现较为简单。In the embodiment of the present application, a first resource pool is configured for the terminal device. When the first terminal device needs to send CSI, it can select a resource to send from the first resource pool, which provides a new mechanism for sending CSI. And the first resource pool may be a resource pool for sending side link data. For example, the resource pool configured for terminal equipment for sending side link data may be directly used as a resource pool for CSI, without additional configuration resources. It is relatively simple to send CSI from the pool.
