Abstract
Description
Technical Field
[0001] The present application relates to the field of communication technology, and in particular to a method and device for adjusting a sounding reference signal (SRS) resource. Background Art
[0002] In wireless communication, the uplink sounding reference signal (SRS) can be a periodic SRS, a semi-persistent scheduling (SPS) SRS or an aperiodic (AP) SRS, a narrowband SRS or a broadband SRS, a single-port SRS or a multi-port SRS. The network side can configure multiple uplink SRS sets for the terminal device, and a resource set contains one or more SRS resources. An SRS resource can be on several consecutive orthogonal frequency division multiplexing (OFDM) symbols.
[0003] Codebook-based or non-codebook transmission can be used to obtain uplink channel state information (CSI) through SRS configuration. SRS resource sets are associated with different transmission reception points (TRP) and are configured to the terminal through radio resource control (RRC) signaling. The terminal needs to configure at most one SRS resource set for codebook-based uplink transmission. The SRS resource set can be configured with multiple SRS resources. The network side will feedback the SRS resource indicator (SRI), and select the SRS resource through the SRI indication.
[0004] In the related art, in order to avoid RRC reconfiguration as much as possible, the largest SRS set is generally selected and configured for the terminal, which results in large signaling overhead and cannot adapt well to changes in terminal capabilities, channels or interference.

[0184] In wireless communication, the uplink sounding reference signal (SRS) can be a periodic SRS, a semi-persistent scheduling (SPS) SRS or an aperiodic (AP) SRS, a narrowband SRS or a wideband SRS, a single-port SRS or a multi-port SRS. The uplink SRS parameters can be configured by the network to the terminal, including the number of ports, frequency domain resource location, time domain resource location, sequence, sequence cycle offset, etc. Figure 5 is a schematic diagram of an SRS mapping area provided in an embodiment of the present application, such as Figure 5 As shown, the network side can configure multiple uplink SRS sets for the terminal device, and a resource set contains one or more SRS resources. An SRS resource can be on several consecutive Orthogonal Frequency Division Multiplexing (OFDM) symbols, and the SRS can be mapped on up to six OFDM symbols (SRS resource area) in an uplink time slot.
[0185] In the uplink enhancement of R17, the multi-TRP-based PUSCH transmission is enhanced. Codebook-based or non-codebook-based transmission can be used to obtain uplink channel state information (CSI) through SRS configuration. SRS resource sets are associated with different transmission reception points (TRP) and are configured to the terminal through radio resource control (RRC) signaling. The terminal needs to configure at most one SRS resource set for codebook-based uplink transmission. The SRS resource set can be configured with multiple SRS resources. The network side will feedback log2(N SRS) bits of SRS Resource Indicator (SRI), and the SRS resource is selected through the SRI indication. Similarly, the base station is based on the measurement of uplink CSI, and the network finally determines the transmission precoding matrix (TPMI) and the number of transmission layers (RI) used by the terminal for actual transmission and notifies the terminal. The data of the terminal in the subsequent uplink transmission needs to be precoded using the PMI and RI specified by the network side. At the same time, the precoded data is mapped to the corresponding antenna port according to the spatial filter SpatialRelationInfo corresponding to the SRS resource indicated by SRI. Different SRS will use different spatial filters for transmission, so the precoded data of the terminal needs to be filtered by the spatial filter used by the SRS indicated by SRI. In this way, the transmission of uplink data from single layer to full rank can be supported.
[0186] Table 1 is used as an example to show the SRI indication method for multiple SRS resources. Table 2 shows the signaling indication methods of TPMI and RI for single-layer transmission, taking 4 antenna ports as an example, respectively, for different UE capabilities. Here, UE capabilities are divided into three types: full correlation, partial correlation and irrelevant, which characterize the correlation capabilities of antenna ports.
[0187] Table 3 and Table 4 correspond to codewords for single-layer transmission of 4 antenna ports.
[0188]
[0189] Table 1
[0190] In the NR system, the base station can configure up to one SRS resource set for the terminal for non-codebook-based uplink transmission, which is achieved by configuring an SRS resource set as "noncodebook". For non-codebook-based uplink transmission, the terminal sends a maximum number of SRS resources that can be transmitted simultaneously to the base station. The resource set can be configured with up to 4 SRS resources, and each SRS resource contains 1 SRS port. The base station can indicate to the terminal through SRI that one or more SRS resources are used for the determination of uplink physical shared channel (Physical Uplink Shared Channel.PUSCH) precoding. The number of SRS resources corresponding to SRI is the number of streams transmitted by PUSCH. When the base station configures only one SRS resource for the terminal for non-codebook uplink transmission, SRI is not included in DCI format 0_1, and the terminal determines the precoding of PUSCH based on the configured SRS resources.
[0191] The following is the SRI indication table corresponding to non-codebook and codebook transmission in the protocol. Table 2 corresponds to L max =1, corresponding to L in Table 3 max =2, corresponding to L in Table 4 max =3.

[0197] Table 4
[0198] In multi-TRP-based PUSCH transmission, whether it is a codebook-based or non-codebook solution, collaborative transmission of two TRPs is currently supported. At the same time, an SRS resource set is configured for each TRP and indicated to the UE through SRI.
[0199] In the related art, in order to avoid RRC reconfiguration as much as possible, the largest SRS set is generally selected and configured for the terminal, which results in large signaling overhead and cannot adapt well to changes in terminal capabilities, channels or interference. At the same time, as the number of antenna panels increases, the problems of flexibility and signaling overhead will become more prominent.
