本申请属于通信技术领域,具体涉及一种SRS资源发送方法、装置、用户设备及存储介质。The present application belongs to the technical field of communications, and in particular relates to a method, device, user equipment and storage medium for sending SRS resources.
在通信系统中,对于高速率传输场景,用户设备(User Equipment,UE)需要发送较为密集的探测参考信号(Sounding Reference Signal,SRS)去获得下行信道状态信息(Downlink Channel State Information,DL CSI),以根据该DL CSI预测/确定后续一段时间的信道信息,以减少资源开销。In the communication system, for high-speed transmission scenarios, the user equipment (User Equipment, UE) needs to send relatively dense sounding reference signal (Sounding Reference Signal, SRS) to obtain downlink channel state information (Downlink Channel State Information, DL CSI), The channel information for a subsequent period of time can be predicted/determined according to the DL CSI, so as to reduce resource overhead.
然而现有方案中,UE是通过配置多个资源集合或多个资源,来实现密集的多个SRS资源的发送,即为每个SRS资源分别配置一个资源集合或一个资源,因此UE发送多个SRS资源时只能在各自配置的资源集合或资源上发送;或者,UE发送SRS资源时,SRS资源内的端口均只能在一个符号上发送出去;如此UE发送SRS资源的灵活性较差。However, in the existing solutions, the UE implements intensive transmission of multiple SRS resources by configuring multiple resource sets or multiple resources, that is, configuring one resource set or one resource for each SRS resource, so the UE sends multiple SRS resources can only be sent on the respective configured resource sets or resources; or, when the UE sends SRS resources, all ports in the SRS resources can only be sent on one symbol; in this way, the flexibility of the UE to send SRS resources is poor.

下面对本申请实施例提供的SRS资源发送方法、装置、用户设备及存储介质中涉及的一些概念和/或术语做一下解释说明。Some concepts and/or terms involved in the SRS resource sending method, device, user equipment, and storage medium provided in the embodiments of the present application are explained below.
1、SRS资源的相关配置:1. Related configuration of SRS resources:
UE被配置了周期上行探测参考信号(SRS)之后,按照所配置的周期发送SRS,其发送带宽、频域位置、传输梳状(transmission comb)等参数由无限资源控制(Radio Resource Control,RRC)配置。After the UE is configured with a periodic uplink sounding reference signal (SRS), it sends the SRS according to the configured period, and its transmission bandwidth, frequency domain position, transmission comb (transmission comb) and other parameters are controlled by Radio Resource Control (RRC) configuration.
非周期SRS是动态触发之后UE发送,非周期SRS的带宽、频域位置、传输梳状等参数是由RRC提前配置的。半持续SRS的配置参数与周期SRS类似,UE只有被激活发送半持续SRS之后,才能发送直到被去激活。SRS的频域信息RRC参数如下:The aperiodic SRS is sent by the UE after being dynamically triggered. The bandwidth, frequency domain position, transmission comb and other parameters of the aperiodic SRS are configured in advance by the RRC. The configuration parameters of the semi-persistent SRS are similar to those of the periodic SRS. The UE can only send the semi-persistent SRS after being activated until it is deactivated. The frequency domain information RRC parameters of SRS are as follows:
传输梳状可以配置为2或4;传输梳状为2时有两个梳状偏移值/量(comb offset)、传输梳状为4时有四个梳状偏移值;The transmission comb can be configured as 2 or 4; when the transmission comb is 2, there are two comb offset values/amount (comb offset), and when the transmission comb is 4, there are four comb offset values;
频域位置(frequency domain position)是在SRS调频发送的情况下第一次发送的子带位置,频域偏移(frequency domain shift)指示在一个带宽部分(Bandwidth Part,BWP)内以物理资源块(physical resource block,PRB)为单位的偏移值,调频(frequency hopping)图样由c-SRS、b-SRS、b-hop值决定。例如,一种方式,RRC配置c-SRS=1,b-SRS=0,频域位置为0,频域偏移为10,那么SRS发送带宽是8个PRB,从第10个PRB开始到第17个PRB。另一种方式,RRC配置c-SRS=1,b-SRS=1,频域位置为0,频域偏移为10,那么SRS发送子带大小是4个PRB,从第10个PRB到第13个PRB是一个子带、从第14个PRB到第17个PRB是另一个子带。The frequency domain position (frequency domain position) is the subband position sent for the first time in the case of SRS FM transmission, and the frequency domain shift (frequency domain shift) indicates that within a bandwidth part (Bandwidth Part, BWP) in a physical resource block (physical resource block, PRB) is the offset value in units, and the frequency hopping pattern is determined by the c-SRS, b-SRS, and b-hop values. For example, in one way, RRC configures c-SRS=1, b-SRS=0, the frequency domain position is 0, and the frequency domain offset is 10, then the SRS transmission bandwidth is 8 PRBs, starting from the 10th PRB to the 1st PRB 17 PRBs. In another way, RRC configures c-SRS=1, b-SRS=1, the frequency domain position is 0, and the frequency domain offset is 10, then the SRS transmission subband size is 4 PRBs, from the 10th PRB to the 1st PRB The 13 PRBs are one subband, and the 14th PRB to the 17th PRB are another subband.
其中,频域位置为0代表UE第一次发送第一个子带、然后跳到第二个子带发送SRS, 如果频域位置为1代表UE第一次发送第二个子带、然后跳到第一个子带发送SRS。Among them, if the frequency domain position is 0, it means that the UE sends the first subband for the first time, and then jumps to the second subband to send SRS. If the frequency domain position is 1, it means that the UE sends the second subband for the first time, and then jumps to the second subband. One subband transmits SRS.
如果传输梳状配置为n2(两个梳状),梳状偏移值为0,那么UE在第一个梳状上发送SRS。例如,1个PRB有12个子载波,梳状偏移值为0代表SRS在偶数子载波上发送,梳状偏移值为1代表SRS在奇数子载波上发送。传输梳状是由RRC配置,即静态配置。If the transmission comb configuration is n2 (two combs) and the comb offset value is 0, then the UE sends SRS on the first comb. For example, 1 PRB has 12 subcarriers, a comb offset value of 0 indicates that SRS is sent on even subcarriers, and a comb offset value of 1 indicates that SRS is sent on odd subcarriers. The transmission comb is configured by RRC, that is, static configuration.
另外,调频使能时按照如下公式进行调频:In addition, when frequency modulation is enabled, frequency modulation is performed according to the following formula:
2、非周期SRS资源集合(resource set):2. Aperiodic SRS resource set (resource set):

If the field is configured as aperiodic, the aperiodic SRS-resource trigger (aperiodic SRS-resource trigger) and aperiodic SRS resource trigger list are included in the aperiodic field. (aperiodic SRS-resource trigger list), respectively select one or two of the trigger candidate states (1, 2, 3) as the trigger state (trigger state) of the set.
网络设备通过下行控制信息(Downlink Control Information,DCI)激活:SRS请求(request)对于没有在小区被配置成补充上行链路(Supplementary Uplink,SUL),用2bits用于指示trigger state;SRS request对于在小区被配置成SUL,用1bit用于non-SUL/SUL指示,用2bits用于指示trigger state。例如,具体指示方式如下:00代表不激活;01代表激活trigger state=1或trigger state list中包含1;10代表激活trigger state=2或trigger state list中包含2;11代表激活trigger state=3或trigger state list中包含3。The network device is activated through downlink control information (Downlink Control Information, DCI): SRS request (request) is used to indicate the trigger state for the SRS request (request) that is not configured as a supplementary uplink (Supplementary Uplink, SUL) in the cell; The cell is configured as SUL, 1 bit is used for non-SUL/SUL indication, and 2 bits are used to indicate trigger state. For example, the specific instructions are as follows: 00 means not activated; 01 means activated trigger state = 1 or trigger state list contains 1; 10 means activated trigger state = 2 or trigger state list contains 2; 11 means activated trigger state = 3 or The trigger state list contains 3.
3、SRS激活时间:3. SRS activation time:
对于usage=码本(codebook)/天线切换(antenna switching),用于激活的物理下行控制信道(Physical Downlink Control Channel,PDCCH)的最后一个符号到被激活的SRS资源之间的最小时间间隔是N2。For usage = codebook (codebook)/antenna switching (antenna switching), the minimum time interval between the last symbol of the activated Physical Downlink Control Channel (PDCCH) and the activated SRS resource is N2 .
对于usage=非码本(non codebook)/波束管理(BM),用于激活的PDCCH的最后一个符号到被激活的SRS资源之间的最小时间间隔是N2+14。其中,N2的单位是符号(symbol),且是按照PDCCH和激活的SRS资源中最小的SCS计算的。For usage=non codebook (non codebook)/beam management (BM), the minimum time interval between the last symbol of the activated PDCCH and the activated SRS resource is N2+14. Wherein, the unit of N2 is a symbol (symbol), and is calculated according to the smallest SCS among the PDCCH and activated SRS resources.
n slot接收到用于激活的非周期(aperiodic)SRS的DCI。n slot receives DCI for active aperiodic SRS.
SRS资源是在

时隙上传输。其中,k是SRS集合中配置的时隙偏移量,支持0到32时隙;与PDCCH和触发的SRS的子载波间隔(Sub-Carrier Spacing,SCS)有关。

Wherein, k is the time slot offset configured in the SRS set, which supports 0 to 32 time slots; it is related to the sub-carrier spacing (Sub-Carrier Spacing, SCS) of the PDCCH and the triggered SRS.
对于LTE而言,对于非周期的SRS触发,如果指定的时隙位置上无法发送SRS,UE会在从指定时隙位置开始后找第一个可以用于发送SRS的时隙用于发送所述SRS,其中指定时隙位置是根据用于触发的PDCCH以及所触发的SRS上配置的时隙偏移确定的。For LTE, for aperiodic SRS triggering, if the SRS cannot be sent at the specified time slot position, the UE will find the first time slot that can be used to send SRS after starting from the specified time slot position to send the SRS. SRS, wherein the designated time slot position is determined according to the PDCCH used for triggering and the time slot offset configured on the triggered SRS.
4、非周期CSI-RS触发:4. Aperiodic CSI-RS triggering:
网络设备通过RRC信令配置资源的准共址(Quasi Co-Location,QCL);RRC配置trigger state。媒体接入控制层控制单元(Media Access Control-Control Element,MAC CE)挑选trigger state子集,DCI来触发CSI-RS trigger state。The network device configures Quasi Co-Location (QCL) of resources through RRC signaling; RRC configures trigger state. The media access control layer control unit (Media Access Control-Control Element, MAC CE) selects the trigger state subset, and the DCI triggers the CSI-RS trigger state.

Wherein, X is the time slot offset of the aperiodic CSI-RS resource; it is related to the PDCCH and the SCS of the triggered CSI-RS.
5、周期和半持续SRS:5. Periodic and semi-continuous SRS:
周期SRS资源是被配置即生效;Periodic SRS resources take effect immediately after they are configured;
半持续SRS需要通过MAC CE激活才生效,也可以通过MAC CE去激活。Semi-persistent SRS needs to be activated through MAC CE to take effect, and can also be deactivated through MAC CE.
