In order to better understand the embodiments of the present application, the random access process related to the present application is described.

The random access process may be a contention-based random access process or a non-contention-based random access process. The random access process may be a four-step random access process (also referred to as a Type-1 random access process) or a two-step random access process (also referred to as a Type-2 random access process).

In the four-step random access process (4-step RACH), the UE first sends message 1 (message 1, MSG.1) to the network, including a preamble; after the network detects the preamble, it will send message 2 (message 2, MSG.2) or a random access response (RAR) message, including the number of the preamble detected by the network and the uplink wireless resources allocated to the UE to send message 3 (message 3, MSG.3); after receiving MSG.2, the UE confirms that at least one of the preamble numbers carried in MSG.2 is consistent with the number of the preamble it sent, and then sends MSG.3 containing contention resolution information according to the resources indicated by RAR; after receiving MSG.3, the network will send message 4 (message 4, MSG.4) containing contention resolution information; after receiving MSG.4, the UE confirms that the resolution information is consistent with that sent by itself in MSG.3, thus completing the four-step random access.

The network includes the uplink grant (UL grant) information in the RAR to indicate the MSG.3 Physical Uplink Shared Channel (PUSCH) scheduling information, and includes the Random Access Preamble ID (RAPID), Temporary Cell Radio Network Temporary Identity (TC-RNTI), Timing Advance (TA), etc. If the network does not receive the MSG.3 PUSCH, it can schedule the retransmission of the MSG.3 PUSCH in the TC-RNTI-scrambled Physical Downlink Control Channel (PDCCH).

For the contention random access process, different UEs randomly select preambles for transmission, so different UEs may select the same preamble to send on the same time-frequency radio resources (RACH opportunity (RACH Occasion, RO) resources), which can be understood as a UE preamble conflict. In this case, different UEs will receive the same RAR, and at this time, different UEs will transmit MSG.3 PUSCH according to the scheduling information in the RAR UL grant. The network decodes the PUSCH (including contention resolution information) sent by the UE on the MSG.3 PUSCH scheduling resources, so the network will include the contention resolution information received in MSG.3 in MSG.4. If the contention resolution information in MSG.4 received by the UE matches the contention resolution information sent by the UE in MSG.3 PUSCH, the UE considers that the contention resolution is successful. If they do not match, the contention resolution is considered unsuccessful.

If the contention resolution is unsuccessful, the UE reselects RACH resources, sends the Physical Random Access Channel (PRACH), and makes the next random access attempt.

In the two-step random access process (2-step RACH), the first step is that the UE sends MsgA to the network. After receiving MsgA, the network sends MsgB to the UE. If the UE does not receive MsgB within a certain period of time, the UE will accumulate the counter that counts the number of times MsgA is sent and resend MsgA. If the counter that counts the number of times MsgA is sent reaches a certain threshold, the UE will switch from the 2-step random access process to the 4-step random access process.

MsgA includes MsgA preamble and MsgA PUSCH. The preamble is sent on the RO for 2-step RACH, and the PUSCH is sent on the MsgA PUSCH resources associated with the MsgA preamble and RO. MsgA PUSCH resources are a set of PUSCH resources configured relative to each PRACH slot, including time-frequency resources and demodulation reference signal (DMRS) resources, and are associated with the PRACH resources in the PRACH slot.

To facilitate a better understanding of the embodiments of the present application, the enhanced duplex mode related to the present application is described.

In the 5G mobile communication system, full duplex enhancement technology is used to adapt to diverse scenarios and business requirements. The main scenarios of 5G include enhanced mobile ultra-wideband (eMBB), ultra-reliable and low latency communication (URLLC), and massive machine type communication (mMTC). These scenarios put forward requirements for the system such as high reliability, low latency, large bandwidth, and wide coverage.

In NR, configuring full-duplex mode can significantly improve the delay and coverage performance of the time division duplex (TDD) system. For example, configuring the subband non-overlapping full-duplex mode, where the non-overlapping subband full-duplex mode means that simultaneous uplink and downlink transmission and reception or transmission and reception are allowed on non-overlapping subband resources within a carrier bandwidth. Since the uplink subband and the downlink subband do not overlap, the self-interference is small, which can reduce transmission delay and enhance coverage.

For a downlink timeslot (DL slot), the network configures (by TDD uplink and downlink common configuration (tdd-UL-DL-ConfigurationCommon) or TDD uplink and downlink dedicated configuration (tdd-UL-DL-ConfigurationDedicated)) the downlink (DL) bandwidth part (Band Width Part, BWP) for the UE, as shown in the timeslot 1 in Figure 2; for an uplink (UL) timeslot, the network configures (by TDD uplink and downlink common configuration (tdd-UL-DL-ConfigurationCommon) or TDD uplink and downlink dedicated configuration (tdd-UL-DL-ConfigurationDedicated)) the UL BWP for the UE, as shown in the timeslot 4 in Figure 3.

For a downlink timeslot (DL slot) (configured by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated), in the full duplex scenario, as shown in Figure 2, there are the following examples (cases):

case 1: Configure DL BWP, such as slot 1;

case 2: Configure DL BWP and uplink sub-band (UL sub-band), such as slot 2.

For an uplink timeslot (UL slot) (configured by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated), in the full duplex scenario, as shown in Figure 3, there are the following cases:

case 3: Configure UL BWP, such as slot 4;

case 4: Configure UL BWP and downlink sub-band (DL sub-band), such as slot 5.

For sub-band full-duplex (SBFD) operation, one SBFD sub-band consists of one resource block (RB) or a set of consecutive RBs with the same transmission direction.

The time unit (e.g., slot or symbol) in which the gNB uses SBFD operation may be referred to as a SBFD time unit (e.g., slot or symbol).

An exemplary duplex mode is: the network side is full-duplex, at the same time, uplink transmission and downlink transmission can be carried out simultaneously at different frequency domain positions. To avoid interference between uplink and downlink, a certain guard band (Guard Band) can be reserved between the frequency domain positions (corresponding to the duplex sub-band) corresponding to different transmission directions; the terminal side is half-duplex, that is, consistent with TDD, at the same time, only uplink transmission or downlink transmission can be carried out, and both cannot be carried out at the same time. It can be understood that in this duplex mode, the uplink transmission and downlink transmission at the same time on the network side can only be for different terminals.

Another exemplary duplex mode is: both the terminal side and the network side are full-duplex, as shown in Figure 4, that is, both the terminal side and the network side work in duplex mode. Specifically, for the terminal side and the network side, at the same time, uplink transmission (uplink, UL) and downlink transmission (downlink, DL) can be carried out simultaneously at different frequency domain positions.

For full-duplex on the UE side, a larger guard band (GB) (larger than the GB of the base station frequency division (FD)) may be required to suppress self-interference, as shown in Figure 5.

For a communication device, simultaneous UL reception and DL transmission will cause self-interference. In order to ensure transmission in the interfered direction, the communication device needs to have the ability to eliminate self-interference, such as reserving a guard band between the receiving band and the transmitting band, but this will reduce the UE throughput.

To facilitate understanding of the embodiments of the present application, the uplink sounding reference signal (Sounding Reference Signal, SRS) resources related to the present application are explained.

In NR, uplink beam training through SRS is supported. However, in the initial access phase, there is no uplink beam management because the terminal does not send SRS. The uplink beam used by the terminal when sending Preamble and Msg3, or MsgA depends on the implementation of the terminal. However, in 4-step RACH, there is a requirement for the consistency of the uplink beam used by the terminal to send Msg3 and the uplink beam of the Physical Uplink Control Channel (PUCCH) carrying the Hybrid Automatic Repeat request Acknowledgement (HARQ-ACK) of Msg4, that is, the terminal needs to ensure that the uplink beam used to send Msg3 is the same as the uplink beam used to send the PUCCH carrying the HARQ-ACK of Msg 4. Similarly, for 2-step RACH, the terminal needs to ensure that the uplink beam used to send Msg A is the same as the uplink beam used to send the PUCCH carrying the HARQ-ACK of Msg B. In the Radio Resource Control (RRC) connected state, the uplink beam training results based on SRS can be used for subsequent uplink transmissions.

When the duplex mode is introduced, how to configure SRS is an urgent problem to be solved.

To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

FIG. 6 is a schematic flow chart of a method 200 for configuring SRS resources according to an embodiment of the present application. As shown in FIG. 6 , the method 200 for configuring SRS resources may include at least part of the following contents:

S210, the network side device sends uplink configuration information to the terminal; wherein the uplink configuration information is used to configure at least one of the following: SRS resources, SRS resource sets; wherein the uplink configuration information is associated with duplex configuration;

Correspondingly, the terminal receives the uplink configuration information from the network side device;

S220: The terminal sends an SRS according to the uplink configuration information.

Correspondingly, the network side device receives the SRS according to the uplink configuration information.

In the embodiment of the present application, the terminal may support full-duplex or half-duplex, and the network side device may support full-duplex or half-duplex. For example, the network side device supports full-duplex, and the terminal supports full-duplex or half-duplex. For another example, the network side device supports half-duplex, and the terminal supports half-duplex.

The duplex mode described in the embodiments of the present application may be, for example, an enhanced duplex mode, or referred to as enhanced duplex, cross duplex (XDD), enhanced full duplex, or enhanced full duplex mode, but the embodiments of the present application are not limited to this.

The duplex configuration described in the embodiments of the present application may be, for example, an enhanced duplex configuration, or a cross duplex (XDD) configuration, or an enhanced full-duplex configuration, but the embodiments of the present application are not limited thereto.

In a specific embodiment, the uplink configuration information is associated with an enhanced duplex configuration. For example, the SRS resource configured by the uplink configuration information can be used for SRS transmission in an enhanced duplex mode.

In some embodiments of the present application, the terminal may determine the duplex configuration according to the uplink configuration information, thus, there is no need to introduce additional duplex configuration signaling overhead.

Therefore, in an embodiment of the present application, the terminal can determine the duplex configuration based on the configuration of the SRS resource or the SRS resource set, without the need for separate signaling for duplex configuration. The duplex configuration is more flexible, and the duplex configuration is associated with the SRS resource, and the SRS can be transmitted in the duplex mode, thereby improving the utilization of system resources and reducing the transmission delay of the SRS.

The duplex configuration described in the embodiment of the present application may refer to: configuring an uplink subband on a downlink time unit, or configuring a downlink subband on an uplink time unit. Thus, duplex transmission of downlink and uplink may be realized on a downlink time unit, or duplex transmission of downlink and uplink may be realized on an uplink time unit.

Therefore, compared to only being able to configure a downlink subband on a downlink time unit, or only being able to configure an uplink subband on an uplink time unit, when the uplink configuration information is associated with the duplex configuration, the network side device can configure the SRS resource on the uplink subband configured on the downlink time unit, and can also configure the SRS resource on the uplink time unit. Therefore, there are more options for the SRS resource location, which is conducive to reducing the transmission delay of the SRS. For example, when the network side device configures multiple SRS resources, the terminal can select the earliest SRS resource to send the SRS, thereby reducing the transmission delay of the SRS.

The reference signal described in the embodiment of the present application includes but is not limited to at least one of the following:

Synchronization Signal Block (SSB), Channel State Information Reference Signal (CSI-RS), message A (MsgA) in two-step random access, MsgA PUSCH, Physical Random Access Channel (PRACH), Tracking reference signal (TRS) (TRS is a reference signal used for time-frequency resource estimation), Sounding Reference Signal (SRS).

The association relationship between the reference signal and the SRS resource described in the embodiment of the present application includes but is not limited to at least one of the following:

The association relationship between SSB and SRS resources, the association relationship between CSI-RS and SRS resources, the association relationship between PRACH resources and SRS resources, the association relationship between MsgA resources and SRS resources, the association relationship between MsgA PUSCH resources and SRS resources, the association relationship between TRS resources and SRS resources, and the association relationship between Configured Grant Physical Uplink Shared Channel (CG PUSCH) resources and SRS resources.

The association relationship described in the embodiment of the present application may also be referred to as a mapping relationship. For example, it may be an equal relationship between two signals or channel resources in terms of transmission characteristics (eg, beams).

For example, the association relationship between the PRACH resource and the SRS resource may mean that the beam used by the SRS sent on the SRS resource and the beam used by the PRACH sent on the PRACH resource are the same.

For example, the SRS is used for uplink beam training, and the SRS beam selected by the terminal can be used as the beam used for subsequent PRACH transmission. Alternatively, the beam used for PRACH transmission can be used as the beam for SRS transmission.

For another example, the association relationship between the MsgA resource and the SRS resource may mean that the beam used by the SRS sent on the SRS resource is the same as the beam used by the MsgA sent on the MsgA resource.

For example, by using SRS to perform uplink beam training, the SRS beam selected by the terminal can be used as the beam used for subsequently sending MsgA. Alternatively, the beam used for sending MsgA can also be used as the beam for sending SRS.

For another example, the association relationship between MsgA PUSCH resources and SRS resources may mean that the beam used by the SRS sent on the SRS resources is the same as the beam used by the MsgA PUSCH sent on the MsgA PUSCH resources.

For example, by using SRS for uplink beam training, the SRS beam selected by the terminal can be used as the beam used for subsequent MsgA PUSCH transmission. Alternatively, the beam used for sending MsgA PUSCH can be used as the beam for sending SRS.

Introducing SRS transmission in the Idle or Inactive state can be used for uplink beam management or uplink capacity enhancement of the terminal.

By introducing the association between SSB/CSI-RS and SRS resources, the terminal can perform uplink beam training before accessing the cell, determine a more appropriate PRACH transmission beam, and improve PRACH reception reliability.

By introducing the association between PRACH resources/MsgA resources/MsgA PUSCH resources and multiple SRS resources, different terminals can use different SRS-associated beams to send the same PRACH, thereby improving the capacity of PRACH.

By introducing the association of multiple PRACH resources/MsgA resources/MsgA PUSCH resources to SRS resources, it is possible to support multiple PRACH/MsgA/MsgA PUSCH resource repetitions using the same SRS resources, thereby improving the reliability of PRACH/MsgA/MsgA PUSCH resource transmission.

The SSB described in the embodiment of the present application may also be called a resource block, which includes at least one of a synchronization signal, a broadcast signal, a broadcast channel (PBCH), and other system messages.

In the embodiment of the present application, the repeated transmission of the SRS may be repeated transmission during an initial transmission of the SRS, or repeated transmission during a retransmission of the SRS.

In the embodiment of the present application, the SRS resource may be an SRS time-frequency resource and/or an SRS sequence. The name of the SRS is only an example and may be replaced by other names, such as an uplink signal resource for a terminal in an idle state or an inactive state.

It should be understood that the embodiments of the present application do not limit the use of SRS, for example, it can be used for beam training, or for terminal positioning, etc. For example, when the terminal is in an inactive state, the network side device can configure SRS resources for the terminal to send SRS for terminal positioning in the inactive state.

In some embodiments, the uplink configuration information may be configured in an idle state (Idle) or a deactivated state (Inactive), or the uplink configuration information may be dynamically configured in a random access phase.

In other words, the embodiment of the present application can obtain the SRS resource configuration in the duplex mode in the idle state (Idle) or the deactivated state (Inactive) or in the random access phase, so that the configuration method of the SRS resource is more flexible, and the duplex configuration can also be determined according to the uplink configuration information without introducing additional duplex configuration signaling overhead.

In some embodiments, the uplink configuration information can also be configured in a connected state. In other words, the embodiment of the present application can obtain the SRS resource configuration in a duplex mode in a connected state, making the configuration of the SRS resource more flexible, and the duplex configuration can also be determined according to the uplink configuration information without introducing additional duplex configuration signaling overhead.

In some embodiments, the terminal determining the duplex configuration according to the uplink configuration information may specifically include:

The terminal determines, according to an SRS resource on at least one downlink time unit, an uplink subband on the at least one downlink time unit;

The SRS resources on the at least one downlink time unit include at least one of the following: part or all of the SRS resources configured by the uplink configuration information, and part or all of the SRS resources in the SRS resource set configured by the uplink configuration information.

Therefore, this embodiment clarifies that the uplink subband on at least one downlink time unit can be determined based on the SRS resources on the at least one downlink time unit. After the uplink subband on the at least one downlink time unit is determined, the duplex configuration on the at least one downlink time unit can be known.

In some embodiments, the downlink time unit may include but is not limited to at least one of the following: orthogonal frequency-division multiplexing (OFDM) symbol, time slot, subframe, frame, microsecond, millisecond, second, minute, hour, day, week, and month.

For example, taking the downlink time unit as a downlink time slot (DL slot), the terminal can determine the uplink subband (uplink subband) on the downlink time slot through the SRS resources on the downlink time slot.

In some embodiments, the terminal determines that part or all of the physical resource blocks (PRBs) occupied by the SRS resources on the at least one downlink time unit are uplink subbands, wherein the SRS resources on the at least one downlink time unit are valid.

Exemplarily, the SRS resource on at least one downlink time unit is valid, which can be understood as: the reference signal and the SRS resource on at least one downlink time unit have a mapping relationship, or in other words, the mapping relationship from the reference signal to the SRS resource on the at least one downlink time unit is satisfied.

It should be noted that the SRS resources need to be mapped (or associated) to the reference signal. The terminal selects a reference signal that meets a certain RSRP quality based on the measurement of the reference signal, and determines the SRS resources for uplink data transmission based on the selected reference signal. Taking the reference signal as SSB as an example, the SRS resources need to be mapped to the SSB. The terminal selects an SSB that meets a certain RSRP quality based on the measurement of the SSB, and determines the SRS resources based on the selected SSB.

For example, taking the downlink time unit as a downlink time slot (DL slot), in all downlink time slots where SRS resources appear, the PRB occupied by the SRS resources is considered to be configured as an uplink subband (uplink subband), and the SRS resources are considered to be valid.

As shown in Figure 7, in the downlink time slot n, part of the PRBs occupied by the SRS resources (PRBs excluding the guard interval) are considered to be configured as uplink subbands, and the SRS resources are considered to be valid.

In some embodiments, in each downlink time unit in at least one downlink time unit, part or all of the bandwidth occupied by at least one SRS resource adjacent to the uplink subband is a guard interval. Specifically, the setting of the guard interval can suppress the self-interference generated by simultaneous reception and transmission.

For example, taking the downlink time unit as a downlink time slot (DL slot), as shown in FIG7 , in the downlink time slot n, the entire bandwidth (or, all PRBs) occupied by an SRS resource adjacent to the uplink subband is the protection interval.

For example, taking the downlink time unit as a downlink time slot (DL slot), as shown in FIG8 , in the downlink time slot n, part of the bandwidth occupied by an SRS resource adjacent to the uplink subband is the protection interval.

In some embodiments, the terminal determining the duplex configuration according to the uplink configuration information may specifically include:

The terminal determines, according to an SRS resource on at least one uplink time unit, a downlink subband on the at least one uplink time unit;

The SRS resource on the at least one uplink time unit includes at least one of the following:

Part or all of the SRS resources configured by the uplink configuration information;

Part or all of the SRS resources in the SRS resource set configured by the uplink configuration information.

Therefore, this embodiment clarifies that the downlink subband on at least one uplink time unit can be determined based on the SRS resources on the at least one uplink time unit. After the downlink subband on the at least one uplink time unit is determined, the duplex configuration on the at least one uplink time unit can be known.

In some embodiments, the uplink time unit may include, but is not limited to, at least one of the following: OFDM symbol, time slot, subframe, frame, microsecond, millisecond, second, minute, hour, day, week, month.

In some embodiments, the terminal determines part or all of the PRBs other than the PRBs occupied by the SRS resources on the at least one uplink time unit as downlink subbands, wherein the SRS resources on the at least one uplink time unit are valid.

In some embodiments, in each uplink time unit of the at least one uplink time unit, part or all of the bandwidth occupied by at least one SRS resource adjacent to the downlink subband is used as a guard interval. Specifically, the setting of the guard interval can suppress the self-interference generated by simultaneous reception and transmission.

Exemplarily, the SRS resource on at least one uplink time unit is valid, which can be understood as:

There is a mapping relationship between the reference signal and the SRS resource in the at least one time unit, or in other words, a mapping relationship between the reference signal and the SRS resource in the at least one uplink time unit is satisfied.

In some embodiments, the at least one SRS resource satisfies at least one of the following:

The mapping relationship between the reference signal and the SRS resource is satisfied (or the reference signal and the SRS resource have a mapping relationship), and is not used to send the SRS;

The mapping relationship between the reference signal and the SRS resource is satisfied (or the reference signal and the SRS resource have a mapping relationship), and is not used to send the SRS when the preset conditions are met;

The mapping relationship between the reference signal and the SRS resource is not satisfied (or in other words, the reference signal and the SRS resource do not have a mapping relationship).

Specifically, this embodiment clarifies the conditions that at least one SRS resource where the guard interval is located must satisfy, which is conducive to better utilization of SRS resources.

In some embodiments, for at least one SRS resource with part or all of the bandwidth as a protection interval, if the mapping relationship from the reference signal to the SRS resource is satisfied, the SRS resource can be considered valid; or, if the SRS resource does not satisfy the mapping relationship from the reference signal to the SRS resource, the SRS resource can be considered not valid.

In some embodiments, at least one SRS resource that uses part or all of the bandwidth as a guard interval may not be used to send SRS, or may not be used to send SRS under a preset condition. The preset condition may be understood as a condition that the sending of SRS does not interfere with or has little interference with the sending of downlink signals or downlink channels.

In some embodiments, the preset condition includes but is not limited to at least one of the following:

The time domain interval between the SRS resource and the reference signal is less than or not greater than the first time threshold;

The frequency domain interval between the SRS resource and the reference signal is less than or not greater than the first frequency threshold;

There is a reference signal transmission in the remaining bandwidth outside the uplink subband;

There is transmission of a downlink common channel or a downlink common signal in the remaining bandwidth outside the uplink sub-band;

There is reception of a reference signal in the remaining bandwidth outside the uplink subband;

The remaining bandwidth outside the uplink sub-band is used for receiving a downlink common channel or a downlink common signal.

Therefore, when a preset condition is met, the at least one SRS resource is not used to send the SRS, thereby avoiding interference of the sending of the SRS with the sending of the reference signal or the downlink common channel or the downlink common signal.

Exemplarily, taking the downlink time unit as a downlink time slot (DL slot) as an example, as shown in FIG. 7 or 8, the remaining bandwidth outside the uplink sub-band may include the bandwidth occupied by the protection interval and the downlink sub-band.

Optionally, the first time threshold may be agreed upon by a protocol, or configured by a network-side device.

Optionally, the first frequency threshold may be agreed upon by a protocol, or configured by a network-side device.

In some embodiments, the preset condition is pre-configured by a network-side device, or the preset condition is agreed upon by a protocol.

In some embodiments, the uplink configuration information is further used to configure a guard interval on the at least one downlink time unit or the at least one uplink time unit. Specifically, the setting of the guard interval can suppress the self-interference generated by simultaneous reception and transmission.

In the embodiment of the present application, in support of enhanced duplex mode, SRS resources may be allowed on the uplink subband of the additionally configured downlink time unit, so a new SRS resource type may appear.

In some embodiments, the SRS resource configured by the uplink configuration information includes but is not limited to at least one of the following types:

SRS resources present in the uplink time unit;

SRS resources that exist in time units with flexible symbols;

SRS resources present in the uplink subband of the downlink time unit;

An SRS resource existing in an uplink subband of a downlink time unit, and no reference signal resource exists in the downlink time unit;

An SRS resource existing in an uplink subband of a downlink time unit, and a reference signal resource existing in the downlink time unit;

SRS resources that are not in the uplink subband of the downlink time unit.

By configuring at least one type of SRS resource, the terminal can use the at least one type of SRS resource to transmit SRS in duplex mode, which can reduce the transmission delay of SRS. And by transmitting SRS on the uplink subband in the downlink time unit, the utilization rate of system resources can be improved.

As a specific example, the SRS resource type may include SRS resources on an uplink subband and SRS resources on a non-uplink subband (eg, a downlink subband or an unconfigured subband).

In some embodiments, the uplink time unit may include, but is not limited to, at least one of the following: OFDM symbol, time slot, subframe, frame, microsecond, millisecond, second, minute, hour, day, week, month.

In some embodiments, the SRS resource set configured by the uplink configuration information satisfies at least one of the following:

Includes different types of SRS resources;

Include SRS resources of the same type;

Mapped to the same reference signal resource, such as the same SSB index, or the same CSI-RS index, or the same preamble, or the same Msg A resource index, or the same Msg A PUSCH resource index;

Mapped to different reference signal resources, for example, different SSB index, or different CSI-RS index, or different preamble, or different Msg A resource index, or different Msg A PUSCH resource index.

That is, an SRS resource set may include SRS resources of different types, or only include SRS resources of the same type, or include SRS resources mapped to the same reference signal resources, or may also include SRS resources mapped to different reference signal resources.

Therefore, this embodiment clarifies the types of SRS resources in the SRS resource set configured by the uplink configuration information and the reference signal resources to which the SRS resource set is mapped, so that more flexible SRS resource set configuration can be achieved.

In some embodiments, the SRS resource set configured by the uplink configuration information is used for repeated transmission of SRS. Optionally, the SRS resource set configured by the uplink configuration information is used for repeated transmission during SRS initial transmission, or the SRS resource set configured by the uplink configuration information is used for repeated transmission during SRS retransmission.

In some embodiments, the uplink configuration information is a common configuration information, wherein the common configuration information is used to configure the SRS resource on the uplink subband and the SRS resource on the non-uplink subband, or the common configuration information is used to configure the SRS resource set on the uplink subband and the SRS resource set on the non-uplink subband. For example, the SRS resource on the non-uplink subband may be an SRS resource on an uplink time unit. For another example, the SRS resource on the non-uplink subband may be an SRS resource on a time unit containing flexible symbols.

That is, the same SSRS resource configuration (i.e., the common SRS resource configuration) can be used to configure two possible types of SRS resources, namely: SRS resources on the UL subband and SRS resources on the non-UL subband.

In some embodiments, the uplink configuration information is two independent configuration information, wherein the two independent configuration information are used to configure the SRS resource on the uplink subband and the SRS resource on the non-uplink subband, or the two independent configuration information are used to configure the SRS resource set on the uplink subband and the SRS resource set on the non-uplink subband. For example, the SRS resource on the non-uplink subband may be an SRS resource on an uplink time unit. For another example, the SRS resource on the non-uplink subband may be an SRS resource on a time unit containing flexible symbols.

That is, two independent SRS resource configurations may be used to respectively configure two possible types of SRS resources. For example, one SRS resource configuration is used to configure the SRS resources on the UL subband, and another SRS resource configuration is used to configure the SRS resources on the non-UL subband.

In some embodiments, the SRS resource configured by the uplink configuration information is associated with the reference signal in at least one of the following ways:

At least two different SRS resources are independently associated with the reference signal, that is, at least two different SRS resources are independently mapped with the reference signal;

At least two different types of SRS resources are independently associated with the reference signal, that is, at least two different types of SRS resources are independently mapped with the reference signal;

At least two different SRS resources are associated with the reference signal together, that is, at least two different SRS resources are mapped with the reference signal together;

At least two different types of SRS resources are associated with the reference signal together, that is, at least two different types of SRS resources are mapped with the reference signal together;

An SRS resource is not associated with a reference signal that overlaps with the SRS resource in the time domain.

Exemplarily, taking the reference signal as SSB as an example, at least two different SRS resources are independently associated with the reference signal, for example, as follows: SRS resource 1 is associated with SSB 0, SRS resource 2 is associated with SSB 1, SRS resource 3 is associated with SSB 0, and SRS resource 4 is associated with SSB 1. In this example, a reference signal may be associated with at least one SRS resource as soon as possible, such as some SRS resources are on the uplink subband (UL subband) and some SRS resources are in the normal uplink bandwidth (UL band), so that a group of SRS resources that are more compact in time and associated with the same reference signal can be selected, which is conducive to completing multiple SRS transmission/repetition with low latency.

Exemplarily, taking the reference signal as SSB as an example, at least two different types of SRS resources are independently associated with the reference signal, for example, as follows: the SRS resources configured on the uplink subband of the downlink slot and the uplink SRS resources on the uplink slot or the flexible slot are independently associated with the SSB resources.

Exemplarily, taking the reference signal as SSB as an example, at least two different types of SRS resources are independently associated with the reference signal, for example, as follows: SRS resources existing in the time slot with flexible symbols are associated with SSB 0, SRS resources existing in the uplink subband of the downlink time slot are associated with SSB 1, and SRS resources not in the uplink subband of the downlink time slot are associated with SSB 3; for another example, SRS resources existing in the time slot with flexible symbols are associated with SSB of odd bits, and SRS resources existing in the uplink subband of the downlink time slot are associated with SSB of even bits. In this example, a reference signal may be associated with at least two different types of SRS resources as soon as possible, such as some SRS resources in the uplink subband (UL subband) and some SRS resources in the normal uplink bandwidth (UL band), so that a group of SRS resources that are more compact in time and associated with the same reference signal can be selected, which is conducive to completing multiple SRS transmission/repetition with low latency.

Exemplarily, taking the reference signal as SSB as an example, at least two different SRS resources are associated with the reference signal together, for example, as follows: relative to the SSB resource, the SRS resource is configured, some SRS resources are on the uplink subband of the downlink slot, and some SRS resources are in the normal uplink slot or the flexible slot, and the association between SSB and SRS is performed in a certain order, without distinguishing what kind of slot the SRS is on. The complexity of the association of SSB to SRS resources can be reduced, and there is no need to distinguish different types of SRS resources.

Exemplarily, taking the reference signal as SSB as an example, at least two different SRS resources are associated with the reference signal together, for example, as follows: SRS resources are associated with SSBs in the order of identification, such as SRS resource 0 is associated with SSB 0, SRS resource 1 is associated with SSB 1, SRS resource 2 is associated with SSB 2, SRS resource 3 is associated with SSB 3, SRS resource 4 is associated with SSB 4, SRS resource 5 is associated with SSB 0, SRS resource 6 is associated with SSB 1, and SRS resource 7 is associated with SSB 2. In this example, the complexity of associating the reference signal with the SRS resource can be reduced, and there is no need to distinguish different types of SRS resources.

Exemplarily, taking the reference signal as SSB as an example, at least two different types of SRS resources are associated with the reference signal together, for example, as follows: SRS resources are associated with SSBs in the order of identification, such as SRS resource 0 is associated with SSB 0, SRS resource 1 is associated with SSB 1, SRS resource 2 is associated with SSB 2, SRS resource 3 is associated with SSB 3, and SRS resource 4 is associated with SSB 4. In this example, the complexity of associating the reference signal with the SRS resource can be reduced, and there is no need to distinguish different types of SRS resources.

Exemplarily, taking the reference signal as SSB as an example, the SRS resource is not associated with the reference signal that overlaps with it in the time domain, for example, it can be as follows: if the SRS resource overlaps with a reference signal in the time domain, the SRS resource is not associated with the reference signal. For example, if the SRS resource on a subband has a reference signal on the same OFDM symbol, the SRS resource can be considered invalid. This can reduce interference with the reference signal.

In some embodiments, a mapping cycle or an association period or an association pattern period between an SRS resource configured by the uplink configuration information and a reference signal is determined by at least one of the following methods:

Method 1: The mapping cycle or association period or association pattern period between at least two different SRS resources and reference signals is determined independently;

Method 2: The mapping cycle or association period or association pattern period between at least two different types of SRS resources and reference signals are independently determined;

Mode 3: A mapping cycle or an association period or an association pattern period between at least two different SRS resources and a reference signal is determined together;

Mode 4: A mapping cycle or an association period or an association pattern period between at least two different types of SRS resources and a reference signal is determined together;

Method 5: The mapping cycle or association period or association mode period between the SRS resource and the reference signal is related to the period of the duplex configuration.

Optionally, for method 1, the mapping cycle or association period or association pattern period between different SRS resources and reference signals may be the same or different.

Optionally, for method 2, the mapping cycle or association period or association pattern period between different types of SRS resources and reference signals may be the same or different.

Optionally, in mode 3, a mapping period (mapping cycle) or an association period (association period) or an association pattern period (association pattern period) between the at least two different SRS resources and the reference signal is a common value determined according to a mapping period (mapping cycle) or an association period (association period) or an association pattern period (association pattern period) between all SRS resources and the reference signal.

For example, when at least two different SRS resources are independently mapped to a reference signal, a mapping cycle or association period or association pattern period between the at least two different SRS resources and the reference signal is a maximum value among all mapping cycles or association periods or association pattern periods between all SRS resources and the reference signal.

Optionally, for method 4, the mapping period (mapping cycle) or association period (association period) or association pattern period (association pattern period) between the at least two different types of SRS resources and the reference signal is a common value determined according to the mapping period (mapping cycle) or association period (association period) or association pattern period (association pattern period) between all types of SRS resources and the reference signal.

For example, when at least two different types of SRS resources are independently mapped to reference signals, a mapping cycle or association period or association pattern period between the at least two different types of SRS resources and the reference signals is a maximum value among the mapping cycles or association periods or association pattern periods between all types of SRS resources and reference signals.

In some embodiments, the mapping cycle between SRS resources and reference signals is the time in which all preconfigured indexed reference signals can be mapped at least once.

In some embodiments, the association period between the SRS resource and the reference signal is the shortest time during which all preconfigured indexed reference signals can be mapped at least once and is an integer multiple of the SRS period.

In some embodiments, the association pattern period between the SRS resource and the reference signal is an integer multiple of the association pattern period between the SRS resource and the reference signal, and the time for mapping the SRS resource and the reference signal to form a pattern. Optionally, the time for mapping the SRS resource and the reference signal to form a pattern is less than or does not exceed a preset time. The preset time may be specified by a protocol, or configured by a network-side device.

In some embodiments, the uplink configuration information is used to configure an SRS resource set, and the uplink configuration information is further used to configure at least one of a time window and a period of the SRS resource set.

For example, the SRS resource set configured by the uplink configuration information is used for repeated transmission of the SRS, and the time window of the SRS resource set may be a time window for repeated transmission of the SRS.

Therefore, in the embodiment of the present application, the network side device can configure the SRS resource or SRS resource set in the duplex mode for the terminal. Further, the terminal can transmit the SRS based on the SRS resource or SRS resource set in the duplex mode, thereby improving the utilization rate of system resources and reducing the transmission delay of the SRS. In addition, the terminal can determine the duplex configuration based on the SRS resource configuration or SRS resource set configuration of the network side device, so that the network side device does not need to perform duplex configuration through separate signaling, making the duplex configuration more flexible.

Furthermore, the embodiments of the present application can support flexible duplex configuration in idle state (Idle)/deactivated state (Inactive), mapping of reference signals to SRS resources (such as CG PUSCH resources), reducing the delay of SRS transmission, and dynamically configuring SRS resources or SRS resource sets based on uplink configuration information, which can improve resource utilization to a greater extent.
