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. Related configuration of SRS resources:

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.

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:

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;

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.

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.

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.

In addition, when frequency modulation is enabled, frequency modulation is performed according to the following formula:

Among them, n _SRS is the number of times to send SRS,

2. Aperiodic SRS resource set (resource set):

The network device is configured through RRC: the RRC parameter SRS resource set contains the resource type field. 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.

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 activation time:

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 .

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 receives DCI for active aperiodic SRS.

SRS resources are at

Transmission on a time slot, for example, when the SRS in the activated cell (cell) is configured with a carrier aggregation (Carrier Aggregation, CA) time slot offset/value (slot offset); or, the SRS resource is in

time slot transmission. 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.

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. Aperiodic CSI-RS triggering:

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.

The network device triggers the aperiodic CSI report by triggering the trigger state, thereby triggering the associated CSI-RS resources. A trigger state can be associated with multiple aperiodic reports (associated report config), and an associated report config will be associated with a report config , and configure x resource sets and corresponding QCL-info (Transmission Configuration Indicator (TCI)-status identification), a report config will be configured with 1 CSI-RS resource configuration (esource config), 1 CSI - RS resource configuration can configure up to 16 CSI-RS resource sets.

n slot receives DCI for active aperiodic CSI reporting.

Aperiodic CSI-RS resources are in

Slot transmission, for example, when the SRS in the activated cell is configured with a CA-slot offset; or, the aperiodic CSI-RS resource is in

time slot transmission. 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. Periodic and semi-continuous SRS:

Periodic SRS resources take effect immediately after they are configured;

Semi-persistent SRS needs to be activated through MAC CE to take effect, and can also be deactivated through MAC CE.

The method for sending SRS resources provided by the embodiments of the present application will be described in detail below through some embodiments and application scenarios with reference to the accompanying drawings.
