In addition, the character "/" in this document generally indicates that the related objects are an "or" relationship.

The embodiment of the present application provides a wireless communication method, which can be used to determine a time slot for sending an SRS.

To facilitate understanding of the embodiments of the present application, the SRS is introduced below.

The Sounding Reference Signal (SRS) signal is an important reference signal in the 5G/NR system and is widely used in various functions in the NR system. For example, the SRS can be used in the following scenarios:

1. For the acquisition of downlink channel state information (UE sounding procedure for DL CSI acquisition)

2. Frequency domain scheduling and precoding determination for uplink transmission;

3. Used for Antenna Switching function;

4. Used for carrier switching (UE sounding procedure between component carriers);

5. Used for positioning function;

6. Cooperate with codebook-based uplink transmission;

7. Cooperate with the uplink transmission based on non-codebook (Non-Codebook based).

A network device can configure one or more SRS resource groups (SRS Resource sets) for a terminal device, and each SRS Resource set can configure one or more SRS resources (SRS resources).

The transmission of the SRS can be divided into periodic (Periodic), semi-persistent (Semi-persistent), and aperiodic (Aperiodic).

Periodic SRS refers to periodically transmitted SRS, and its period and time slot offset are configured by RRC signaling. Once the terminal device receives the corresponding configuration parameters, it will send SRS according to a certain period until the RRC configuration is invalid. The spatial correlation information (Spatial Relation Info) of the periodic SRS is also configured by RRC signaling. The spatial correlation information may indicate a channel state information reference signal (Channel State Information Reference Signal, CSI-RS), a synchronization signal/physical broadcast channel block (Synchronization Signal/PBCH Block, SSB) or a reference SRS. For example, the transmission beam of the periodic SRS may be indicated in an implicit manner. For example, the terminal device determines the transmission beam of the periodic SRS according to the indicated CSI-RS/SSB. For another example, the terminal device may determine the transmission beam used for transmitting the SRS on the SRS resource through the spatial correlation information of the SRS resource.

The period and slot offset of semi-persistent SRS are configured by RRC signaling, but its activation and deactivation signaling is carried by MAC CE. The terminal device starts to transmit SRS after receiving the activation signaling until it receives the deactivation signaling. The spatially related information (transmission beam) of the semi-persistent SRS is carried along with the MAC CE that activates the SRS.

After receiving the period and time slot offset configured by RRC, the terminal equipment determines the time slot that can be used to transmit SRS according to the following formula:

Among them, T _SRS and T _offset are the configured period and offset, n _f and

are the radio frame and time slot numbers, respectively.

Aperiodic SRS transmission means that the network device can trigger the SRS transmission of the terminal device through DCI. The trigger signaling for triggering aperiodic SRS transmission can be either through the DCI bearer for scheduling PUSCH/PDSCH in the UE-specific search space or the common search space (Common search space), or through the DCI format 2_3 in the common search space. bear.

Wherein, DCI format 2_3 can not only be used to trigger aperiodic SRS transmission, but also can be used to configure a power control command (TPC) command of SRS on a group of UEs or a group of carriers at the same time.

Table 1 SRS trigger signaling

For example, if the value of the SRS request field in the DCI is 11, the trigger signaling of the SRS indicates that the SRS resource group with the higher layer parameter aperiodic SRS resource trigger (aperiodicSRS-ResourceTrigger) set to 3 is used for SRS transmission.

After receiving the aperiodic SRS trigger signaling (eg DCI), the terminal device performs SRS transmission on the aperiodic SRS resource group indicated by the trigger signaling. The time slot offset (slot offset) between the trigger signaling and the SRS transmission may be configured by higher layer signaling (RRC). The network device pre-instructs the terminal device configuration parameters of each SRS resource group through high-level signaling, including time-frequency resources, sequence parameters, power control parameters, and the like. In addition, for each SRS resource in the triggered SRS resource group, the terminal device can also determine the transmission beam used for transmitting the SRS on the resource through the spatial correlation information of the resource, and the spatial correlation information can be configured for each SRS through RRC resource.

In the New Radio (NR) system, in order to support various possible deployment scenarios and various new service types in the future, the system design is very flexible. For example, the uplink and downlink resources can be transmitted through high-level signaling and physical layer signaling. to indicate and adjust. Therefore, some symbols in a slot or a slot may be used for transmission in different directions at different times, for example, a certain time can be used for uplink transmission, and a certain time can be used for downlink transmission.

However, as mentioned above, for the aperiodic sounding reference signal (Sounding Reference Signal, SRS), its slot offset (slot offset) can be configured by high-level signaling, which is equivalent to before the RRC signaling reconfigures other values. , the time slot offset between each trigger signaling and SRS transmission is constant, resulting in a fixed relative position between the time slot used to receive the trigger signaling and the time slot used to send the SRS, which increases the restriction and Reduced system flexibility.

For example, assuming that the time slot offset is k, if the SRS is to be triggered to transmit on slot n+k, the corresponding trigger signaling can only be sent on slot n, which limits the timing of sending trigger signaling, and gives the network device The scheduling of jobs adds additional unnecessary constraints.

For another example, when a certain slot, or some symbols on a certain slot are dynamically changed from uplink transmission to downlink transmission, a certain aperiodic SRS may not be transmitted. For example, if slot n+k is changed to be used for downlink transmission, the trigger SRS signaling sent on slot n is invalid, or the trigger signaling cannot be sent on slot n.

In some embodiments of the present application, if the network device sends SRS trigger signaling on slot n, the terminal device can transmit SRS on slot n+k or the first valid slot after that. By transmitting SRS on slot n+k or the first effective slot after that, although the success rate of transmitting SRS can be improved, the efficiency is not high, and the configuration and scheduling complexity of network equipment will be increased. The main reason is that the effective slot is not It is fixed and needs to be determined according to related configurations or factors (eg, uplink and downlink time slot configuration and/or indication).

Further, an embodiment of the present application provides a wireless communication method.

It should be noted that, in this embodiment of the present application, a time slot that can or can be used to transmit an SRS is referred to as a valid time slot (valid slot).

FIG. 2 shows a schematic flowchart of a wireless communication method 200 according to an embodiment of the present application, and the method 200 may be executed interactively by a terminal device and a network device. The terminal device shown in FIG. 2 may be the terminal device shown in FIG. 1 , and the network device shown in FIG. 2 may be the access network device shown in FIG. 1 .

As shown in FIG. 2, the method 200 may include:

S210: The terminal device receives first indication information sent by the network device, where the first indication information is used to indicate that the aperiodic sounding reference signal SRS trigger signaling on the first cell is used to trigger the SRS on at least one second cell.

For example, after receiving the first indication information and receiving the aperiodic SRS trigger signaling on the first cell, the terminal device may trigger the terminal device to send SRS on the at least one second cell.

It should be noted that the cell involved in the embodiments of the present application may be equivalent to the carrier. For example, a cell may be equivalent to a component carrier (Component Carrier, CC) in a CA scenario. In other words, the first indication information may be used to indicate that the aperiodic SRS triggering signaling on the first carrier is used to trigger the SRS on at least one second carrier. In addition, the at least one second cell may be a cell, a group of cells, or a plurality of cells, which is not specifically limited in this application.

For example, if the at least one second cell is a second cell, it is equivalent to that the first indication information is used to indicate that the aperiodic SRS trigger signaling on the first cell can be used to trigger the SRS on another cell . For another example, if the at least one second cell is a group of cells, it is equivalent to that the first indication information can be used to indicate that the aperiodic SRS trigger signaling on the first cell can be used to trigger the SRS on a group of cells. . For another example, if the at least one second cell is a plurality of cells, it is equivalent that the first indication information can be used to indicate that the SRS triggering command on the first cell can be used to trigger the SRS on the multiple cells. It should be understood that the group of cells or the plurality of cells may include the first cell or may not include the first cell, which is not specifically limited in this embodiment of the present application.

Through the first indication information, the aperiodic SRS triggering signaling on the first cell can trigger the SRS transmission of the terminal device on at least one second cell, in other words, the cross-cell (or Triggered transmission of aperiodic SRS across carriers).

In some embodiments of the present application, the first indication information is used to indicate aperiodic SRS trigger signaling on the first cell or the first bandwidth part BWP of the first cell, used to trigger the first The SRS on the cell or the at least one second cell corresponding to the first BWP.

In other words, the SRS on the at least one second cell corresponding to the first cell or the first BWP can be understood as: the first indication information is configured for the first cell or the first BWP , and the first indication information indicates the at least one second cell. Equivalently, for different cells, or for different BWPs of a cell, the cells that are configured to activate the aperiodic SRS at the same time may be different. Thereby, the flexibility of configuration can be improved, thereby improving the optimization performance of the network device.

In some embodiments of the present application, the first indication information is used to indicate a first trigger state, or in aperiodic SRS trigger signaling on the first cell or the first bandwidth part BWP on the first cell The first trigger state is used to trigger the SRS on the at least one second cell corresponding to the first trigger state.

In other words, the first indication information is configured for the first trigger state, and the first indication information indicates the at least one second cell. Equivalently, two different trigger states may trigger aperiodic SRS transmission on different cells. For example, trigger state 1 may trigger aperiodic SRS transmission on cell 0 and cell 1, and trigger state 2 may trigger aperiodic SRS transmission on cell 0, cell 1, and cell 2.

For example, the first indication information involved in this embodiment of the present application may be configured for a terminal device. In other words, the first indication information is configured for the trigger state of the terminal device. That is, the correspondence between the first trigger state indicated by the first indication information and the at least one second cell is applicable to each cell of the terminal device, or to each BWP of each cell of the terminal device.

For example, the first indication information involved in the embodiments of the present application may be configured for a target cell group (Cell group) of the terminal device. In other words, the first indication information is configured for a trigger state on a target cell group of the terminal device. That is, the correspondence between the first trigger state indicated by the first indication information and the at least one second cell is applicable to each cell of the one target cell group, or to each BWP of each cell of the one target cell group.

It should be noted that the target cell group may refer to a cell group under a dual connection (Dual Connection, DC). For example, a master cell group (MCG, Master Cell group), or a secondary cell group (SCG, Secondary Cell group). However, the cell group formed by at least one second cell or at least one third cell involved in this application can be understood as a cell group formed by one or more cells that can be triggered by an aperiodic SRS trigger signaling; The first cell group, the second cell group, the cell group indicated by the first indication information, or the cell group indicated by the second information.

Optionally, the first trigger state is a non-zero trigger state.

In some embodiments of the present application, the first indication information is carried by first radio resource control (Radio Resource Control, RRC) signaling, and the first RRC signaling is configured by any one of the following:

SRS configuration SRS-Config;

Serving cell configuration ServingCellConfig;

Special cell configuration SpCellConfig;

Secondary cell configuration SCellConfig;

Serving cell shared configuration ServingCellConfigCommon;

Uplink configuration UplinkConfig;

Bandwidth Part Uplink BWP-Uplink;

Bandwidth Partial Shared Uplink BWP-UplinkCommon; or

The bandwidth portion is dedicated to the uplink BWP-UplinkDedicated.

In some embodiments of the present application, the first indication information is used to indicate aperiodic SRS trigger signaling on the first cell of the terminal device or the first cell of the cell group (Cell Group), using for triggering the SRS on the at least one second cell corresponding to the terminal device or the cell group.

In other words, the first indication information is configured for the terminal device or a cell group including the first cell, and the first indication information indicates the at least one second cell. Equivalently, for different cells or different cells in the same cell group, the cells that are configured to activate the aperiodic SRS at the same time may be the same. Therefore, the network device and the terminal device are simple to implement and process, and the implementation complexity can be reduced.

In some embodiments of the present application, the first indication information is carried through the second radio resource control RRC signaling, and the second RRC signaling is configured through the cell group configuration CellGroupConfig.

In some embodiments of the present application, the first indication information indicates the at least one second cell through an indication field in the RRC signaling, wherein the aperiodic SRS trigger signaling on the first cell is used for Triggering the SRS on the at least one second cell.

In other words, the first indication information indicates that the aperiodic SRS triggering signaling on the first cell is used to trigger the SRS on at least one second cell through the indication field in the RRC.

In some embodiments of the present application, if the value corresponding to the indication field is a preset value, the at least one second cell is all active cells of the terminal equipment to which it belongs, or the at least one second cell is the terminal to which it belongs The device corresponds to all active cells of the cell group.

In some embodiments of the present application, if the value corresponding to the indication field is used to indicate the first cell group, the at least one second cell is all active cells in the first cell group. Optionally, the maximum number of cells in the first cell group is 2, 4, 8 or 32.

In some embodiments of the present application, if the value corresponding to the indication field is used to indicate the first cell group, the at least one second cell is the first cell and all active cells in the first cell group. Optionally, the maximum number of cells in the first cell group is 1, 2, 3, 4, 7, 8, 31 or 32.

In some embodiments of the present application, if the indication field is not configured, or is configured with a specific value, the at least one second cell is the first cell, that is, an aperiodic SRS trigger on the same cell The signaling only triggers aperiodic SRS transmission on the local cell.

In some embodiments of the present application, the value corresponding to the indication field indicates the first cell group through a bitmap or a cell identifier.

It should be understood that the cell identifier may also be referred to as a cell code, which is not specifically limited in this application.

In some embodiments of the present application, the method 200 may further include:

Receive third RRC signaling, where the third RRC signaling is used to configure at least one cell, and the at least one cell includes the first cell and the at least one second cell.

For example, the terminal device receives the third RRC signaling sent by the network device.

In other words, the network device sends the third RRC signaling to the terminal device to configure the at least one cell.

It should be noted that, for SRS, transmission needs to be performed based on an SRS resource group (SRS-ResourceSet) or an SRS resource (SRS-Resource). In other words, the SRS sent by the terminal device may be an SRS resource group or an SRS corresponding to an SRS resource. The slot offset of the SRS corresponding to the SRS resource group is configured for the SRS resource group, and the slot offset corresponding to the SRS resource is configured for the SRS resource. The SRS corresponding to the SRS resource group introduced above may also be referred to as a common SRS. Optionally, the usage field in the SRS resource group may be configured as one of beam management (beamManagement), codebook (codebook), non-codebook (nonCodebook), and antenna switching (antennaSwitching). The SRS corresponding to the SRS resource may also be an SRS used for positioning, which is configured through RRC signaling SRS-PosResource-r16, and the corresponding SRS resource group is configured through RRC signaling SRS-PosResourceSet-r16. In order to simplify the description later, only ordinary SRS is used as an example for introduction in some places, but the solution is also applicable to positioning SRS.

In some embodiments of the present application, the SRS resource groups of different cells in the first cell and the at least one second cell are configured through different SRS resource group SRS-ResourceSet signaling, and the SRS of the first cell The resource group and the SRS resources in different SRS resource groups in the SRS resource group of the at least one second cell are configured through different SRS resource SRS-Resource signaling.

It should be noted that the SRS resource groups involved in the various embodiments of the present application are all aperiodic SRS resource groups, and the SRS resources are all aperiodic SRS resources.

For example, the SRS resource group SRS-ResourceSet signaling or the SRS resource SRS-Resource signaling is configured through the SRS configuration SRS-Config.

In some embodiments of the present application, for multiple trigger states corresponding to the SRS resource group of the first cell and the SRS resource group of the at least one second cell, through the SRS resource group information element SRS-ResourceSet IE Aperiodic SRS resource triggers aperiodicSRS-ResourceTrigger and/or aperiodicSRS resource trigger list aperiodicSRS-ResourceTriggerList configuration, the aperiodicSRS-ResourceTrigger is used to configure a trigger state in the multiple non-zero trigger states, and the aperiodicSRS-ResourceTriggerList uses for configuring one or more trigger states of the plurality of non-zero trigger states.

For example, the value of the aperiodicSRS-ResourceTrigger is an integer from 1 to N-1, where N represents the number of aperiodic SRS trigger states; the value of each element in the aperiodicSRS-ResourceTriggerLis is from 1 to N-1 the integer.

For example, the N is greater than or equal to 4; if N is greater than 4, the N is indicated by the network device to the terminal device, or the N is determined based on the capability of the terminal device to report to the network device.

In some embodiments of the present application, the SRS resource group of each of the at least one second cell is configured with at least one time slot offset; the method 200 may further include:

Example 1:

In this embodiment, the first indication information is configured for the first cell or the first BWP.

step 1:

The terminal device receives the cell configuration information sent by the network device through RRC signaling.

For example, cell aggregation (Carrier Aggregation, CA) configuration information. A cells are configured therein. For each cell in one or more of the A cells (denoted as B, B<=A) (in some cases, some cells may not be configured with the corresponding aperiodic SRS, so it is written as one of A or more), the network device carries the SRS configuration information through RRC signaling, and configures one or more SRS resource groups, and each SRS resource group includes one or more SRS resources. The following description is for a certain cell in the B cells, and the configurations on different cells may be independent. The following description takes the cell Z as an example.

Optionally, the SRS resource group on cell Z is configured through RRC signaling SRS-ResourceSet, and the SRS resources are configured through RRC signaling SRS-Resource.

Optionally, the usage field in the SRS-ResourceSet signaling may be configured as one of beam management (beamManagement), codebook (codebook), non-codebook (nonCodebook), and antenna switching (antennaSwitching).

Optionally, the SRS resource group on the cell Z is configured with multiple (denoted as M, M>=1) trigger states. Optionally, each trigger state corresponds to a value of the SRS request field in the aperiodic SRS trigger signaling, that is, a code point. For example, the value of the trigger state in Table 1.

Optionally, the above multiple trigger states are configured through aperiodicSRS-ResourceTrigger and/or aperiodicSRS-ResourceTriggerList in the SRS-ResourceSet IE, where aperiodicSRS-ResourceTrigger is configured with one value, and aperiodicSRS-ResourceTriggerList is configured with one or more values.

For another example, the value of N is determined to be 4 or greater (eg, 8 or 16) according to the configuration information sent by the network device; of course, in other alternative embodiments, other names may be used. By increasing the number of states corresponding to aperiodic SRS trigger signaling, the flexibility of DCI triggering aperiodic SRS can be improved, and system performance can be improved, thereby enabling cross-cell triggering of aperiodic SRS, reducing DCI overhead, and increasing system flexibility. Optionally, the configuration information indicates the terminal equipment through RRC signaling or MAC CE signaling. Optionally, the terminal device informs the network device through the terminal device capability reporting information that it can support more aperiodic SRS trigger states (Maximum number of SRS trigger states), that is, N is greater than 4, so that the network device determines N based on the capability reported by the terminal device. .

Optionally, the RRC signaling is configured through SRS-Config.

Step 2:

For the cell Z or the BWP Y of the cell Z, the network device indicates through the first indication information which cells can trigger the SRS on the aperiodic SRS trigger signaling transmitted on the cell Z or the BWP Y of the cell Z.

Optionally, when the network device does not indicate relevant information through the above signaling, the aperiodic SRS trigger signaling sent on the cell Z or the BWP Y of the cell Z only triggers the SRS sent on the uplink corresponding to the cell Z. Equivalently, when the terminal device does not receive the first indication information, the original triggering method is used.

Option 1:

The network device configures an indication field through RRC signaling. If the value corresponding to the indication field is a predetermined value, the aperiodic SRS trigger signaling sent on cell Z or BWP Y of cell Z triggers all current The corresponding aperiodic SRS transmission on the active cell. For example, in the case where the corresponding aperiodic SRS is configured for the corresponding active cell. Based on this, not only the first indication information can be simplified, but also the overhead of aperiodic SRS trigger signaling (DCI) can be reduced. Equivalently, the terminal device receives aperiodic SRS trigger signaling in one cell, and the same signaling can trigger aperiodic SRS transmission in all cells.

Option 2:

For example, in the case where the corresponding aperiodic SRS is configured for the corresponding active cell. Compared with option 1, it can more flexibly control which cells can trigger aperiodic SRS transmission by an aperiodic SRS trigger signaling, instead of triggering aperiodic SRS transmission on all active cells, which can not only improve the ability of network equipment to trigger SRS. flexibility, but also to improve system performance.

Optionally, the above indication field indicates a group of cells through a bitmap. For example, if the corresponding bit is a specified value (for example, 1), the cell corresponding to this bit belongs to the group of cells. In many cases, signaling overhead can be reduced through bitmap.

Optionally, the indication field indicates at most 32, or 8, or 4, or 2 cells.

Optionally, the above-mentioned indication field indicates a group of cells through a cell identity, that is, the indication field includes the identity of each cell in the group of cells, and when the number of cells in the group is small, signaling overhead can be reduced. .

Optionally, the indication field indicates at most 32, or 8, or 4, or 2 cells.

Option 3:

The network device configures an indication field through RRC signaling, the indication field indicates a group of cells, and the group of cells includes one or more cells, cell Z or aperiodic SRS trigger signaling sent on the BWP Y of cell Z Aperiodic SRS transmissions corresponding to the terminal equipment on all active cells in the group of cells are triggered. For example, in the case where the corresponding aperiodic SRS is configured for the corresponding active cell. In addition, aperiodic SRS transmission corresponding to cell Z or BWP Y of cell Z is triggered. Compared with option 1, it can more flexibly control which cells can trigger aperiodic SRS transmission by an aperiodic SRS trigger signaling, instead of triggering aperiodic SRS transmission on all active cells, which can not only improve the ability of network equipment to trigger SRS. flexibility, but also to improve system performance. Compared with option 2, for option 2, aperiodic SRS triggering signaling on cell Z can trigger aperiodic SRS transmission on cell Z only if the group of cells indicated by the indication field includes cell Z; option 3 On the basis of 2, regardless of whether the group of cells indicated by the indication field includes cell Z, the aperiodic SRS trigger signaling on cell Z can trigger the aperiodic SRS transmission on cell Z; equivalently, the indication field can The indication to cell Z is reduced, thereby reducing resource overhead.

Optionally, the indication field indicates at most 32, or 8, or 4, or 2 cells.

Optionally, the indication field indicates at most 31, or 7, or 3, or 1 cells.

Optionally, the indication field indicates at most 32, or 8, or 4, or 2 cells.

For each cell in the above determined cells (denoted as Z'), the aperiodic SRS corresponding to the SRS resource group corresponding to the value of the first signaling is sent, because it is configured in the aperiodic SRS resource group on Z' There is a trigger state, so each Z' has an aperiodic SRS resource group corresponding to the first signaling value value. The corresponding SRS resource group is configured with one slot offset (slot offset) or multiple slot offsets.

Optionally, the terminal device receives the aperiodic SRS trigger signaling (such as DCI) on the time slot slot n of the cell Z, and the terminal device determines the corresponding time slot offset of the cell Z' according to the time slot offset corresponding to the SRS resource group where the SRS resource is located. SRS resources are transmitted on slot n'.

As another example, slot n’ can be determined based on the following formula:

Wherein, the u _SRS represents the subcarrier spacing configuration corresponding to the SRS, the u _PDCCH represents the subcarrier spacing configuration corresponding to the physical downlink control channel PDCCH used by the trigger signaling, and the

and the u _{offset, PDCCH} respectively depends on the time slot offset for carrier aggregation CA configured by the upper layer for receiving the physical downlink control channel PDCCH

and u _offset , the

and the u _{offset, the SRS} respectively depends on the slot offset for carrier aggregation CA configured by the upper layer for transmitting the SRS

and u _offset , the k represents the slot offset corresponding to the SRS resource group, and the n represents the first slot. also,

and u _offset may be the relevant parameters of the slot offset for CA specified in the communication standard.

Optionally, according to the time slot offset k corresponding to the SRS resource group (in the case that the SRS resource group is configured with 1 time slot offset, or when one time slot offset is activated), or the MAC signaling is activated The time slot offset k corresponding to the SRS resource group of the k (when the SRS resource group is configured with multiple time slot offsets), the kth or k+1th effective time slot on cell Z' after the time slot where the aperiodic SRS trigger signaling is located is slot n '. In this way, the aperiodic SRS can be triggered more flexibly, and the probability of signaling congestion in response to the aperiodic SRS triggering is reduced. Optionally, the valid time slot is a time slot that can transmit the SRS.
