It should be noted that in the embodiment of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0040] To facilitate a better understanding of the embodiments of the present application, the random access process related to the present application is described.

[0041] The random access procedure may be a contention-based random access procedure or a non-contention-based random access procedure. The random access procedure may be a four-step random access procedure (also known as a Type-1 random access procedure) or a two-step random access procedure (also known as a Type-2 random access procedure).

[0042] In the four-step random access procedure (4-step RACH), the UE first sends message 1 (MSG.1) containing a preamble to the network. After detecting the preamble, the network sends message 2 (MSG.2) or a Random Access Response (RAR) message, which contains the preamble number detected by the network and the uplink radio resources allocated to the UE for sending message 3 (MSG.3). After receiving MSG.2, the UE confirms that at least one of the preamble numbers carried in MSG.2 matches the number of the preamble it sent. It then sends MSG.3 containing contention resolution information based on the resources indicated by the RAR. After receiving MSG.3, the network sends message 4 (MSG.4) containing contention resolution information. After receiving MSG.4, the UE confirms that the resolution information it sent in MSG.3 matches the contention resolution information it sent, completing the four-step random access procedure.

[0043] The network includes uplink grant (UL grant) information in the RAR to indicate the scheduling information of the MSG.3 Physical Uplink Shared Channel (PUSCH), and also includes information such as the Random Access Preamble ID (RAPID), Temporary Cell Radio Network Temporary Identity (TC-RNTI), and Timing Advance (TA). If the network does not receive the MSG.3 PUSCH, it can schedule the retransmission of the MSG.3 PUSCH in the Physical Downlink Control Channel (PDCCH) scrambled by the TC-RNTI.

[0044] For the contention-based random access process, different UEs randomly select preambles for transmission. In this way, different UEs may select the same preamble to send on the same time-frequency radio resources (RACH Occasion (RO) resources). This situation can be understood as a UE preamble conflict. In this case, different UEs will receive the same RAR. 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.

[0045] If the contention resolution is unsuccessful, the UE reselects RACH resources, performs physical random access channel (PRACH) transmission, and makes the next random access attempt.

[0046] In the two-step random access (2-step RACH) process, the first step is for the UE to send 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 increments the counter that counts the number of times MsgA has been sent and resends MsgA. If the counter counts the number of times MsgA has been sent, the UE switches from the 2-step random access process to the 4-step random access process.

[0047] MsgA consists of the MsgA preamble and MsgA PUSCH parts. The preamble part is sent on the Ro used for 2-step RACH, and the PUSCH part is sent on the MsgA PUSCH resources associated with the MsgA preamble and Ro. MsgA PUSCH resources are a set of PUSCH resources configured for each PRACH time slot, including time-frequency resources and demodulation reference signal (DMRS) resources, and are associated with the PRACH resources within the PRACH slot.

[0048] To facilitate a better understanding of the embodiments of the present application, the enhanced duplex mode related to the present application is described.

[0049] In 5G mobile communication systems, full-duplex technology has been enhanced to accommodate diverse scenarios and service requirements. Key 5G scenarios include enhanced mobile broadband (eMBB), ultra-reliable and low-latency communication (URLLC), and massive machine-type communication (mMTC). These scenarios place high demands on the system for reliability, low latency, high bandwidth, and wide coverage.

[0050] In NR, configuring full-duplex mode can significantly improve the latency and coverage performance of the Time Division Duplex (TDD) system. Specifically, configuring subband non-overlapping full-duplex mode allows simultaneous uplink and downlink transmission and reception on non-overlapping subband resources within a carrier bandwidth. Because the uplink and downlink subbands do not overlap, self-interference is reduced, which can reduce transmission delay and enhance coverage.

[0051] For a downlink time slot (DL slot), the network configures the downlink (DL) bandwidth part (Band Width Part, BWP) for the UE (configured by TDD uplink and downlink common configuration (tdd-UL-DL-ConfigurationCommon) or TDD uplink and downlink dedicated configuration (tdd-UL-DL-ConfigurationDedicated)), as shown in time slot 1 in Figure 2; for an uplink (UL) time slot, the network configures the UL BWP for the UE (configured by TDD uplink and downlink common configuration (tdd-UL-DL-ConfigurationCommon) or TDD uplink and downlink dedicated configuration (tdd-UL-DL-ConfigurationDedicated)), as shown in time slot 4 in Figure 3.

[0052] For a downlink timeslot (DL slot) (configured by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated), in a full duplex scenario, as shown in Figure 2, there are the following cases:

[0053] Case 1: Configure DL BWP, such as slot 1;

[0054] Case 2: Configure DL BWP and uplink sub-band (UL sub-band), such as slot 2.

[0055] For an uplink timeslot (UL slot) (configured by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated), in a full duplex scenario, as shown in Figure 3, there are the following cases:

[0056] Case 3: Configure UL BWP, such as slot 4;

[0057] Case 4: Configure UL BWP and downlink sub-band (DL sub-band), such as slot 5.

[0058] 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.

[0059] The time unit (e.g., slot or symbol) in which the gNB uses SBFD operation may be referred to as an SBFD time unit (e.g., slot or symbol).

[0060] An exemplary duplex mode is: full-duplex on the network side, where uplink and downlink transmissions can occur simultaneously at different frequency domain locations at the same time. To prevent interference between uplink and downlink, a guard band (Guard Band) can be reserved between the frequency domain locations corresponding to different transmission directions (corresponding to duplex subbands); half-duplex on the terminal side, consistent with TDD, where only uplink or downlink transmissions can occur at the same time, not both. It is understood that in this duplex mode, uplink and downlink transmissions on the network side can only be directed to different terminals at the same time.

[0061] 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.

[0062] For full-duplex at 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 FIG5 .

[0063] For a communication device, simultaneous UL reception and DL transmission can cause self-interference. To ensure transmission in the interfered direction, the communication device needs to have self-interference cancellation capabilities, such as reserving a guard band between the receive and transmit bands. However, this reduces UE throughput.

[0064] To facilitate understanding of the embodiments of the present application, an uplink sounding reference signal (SRS) resource related to the present application is described.

[0065] Uplink beam training via SRS is supported in NR. 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 the Preamble and Msg3, or MsgA depends on the terminal's implementation. 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 MsgA is the same as the uplink beam used to send the PUCCH carrying the HARQ-ACK of Msg B. In a Radio Resource Control (RRC) connected state, the SRS-based uplink beam training result can be used for subsequent uplink transmission.

[0066] When introducing the duplex mode, how to configure SRS is an urgent problem that needs to be solved.

[0067] 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 all of them fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0068] FIG6 is a schematic flowchart of a method 200 for configuring SRS resources according to an embodiment of the present application. As shown in FIG6 , the method 200 for configuring SRS resources may include at least part of the following contents:

[0069] 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;

[0070] Correspondingly, the terminal receives the uplink configuration information from the network side device;

[0071] S220: The terminal sends an SRS according to the uplink configuration information.

[0072] Correspondingly, the network-side device receives the SRS according to the uplink configuration information.

[0073] In an 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.

[0074] The duplex mode described in the embodiments of the present application may be, for example, an enhanced duplex mode, or 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.

[0075] 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.

[0076] In a specific embodiment, the uplink configuration information is associated with enhanced duplex configuration. For example, the SRS resources configured by the uplink configuration information can be used for SRS transmission in the enhanced duplex mode.

[0077] In some embodiments of the present application, the terminal may determine the duplex configuration according to the uplink configuration information, thus eliminating the need to introduce additional duplex configuration signaling overhead.

[0078] 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 duplex mode, thereby improving the utilization of system resources and reducing the transmission delay of the SRS.

[0079] The duplex configuration described in the embodiments of the present application may refer to configuring an uplink subband in a downlink time unit, or configuring a downlink subband in an uplink time unit, thereby enabling downlink and uplink duplex transmission in a downlink time unit, or enabling downlink and uplink duplex transmission in an uplink time unit.

[0080] Therefore, compared to only being able to configure downlink subbands in downlink time units, or only being able to configure uplink subbands in uplink time units, when uplink configuration information is associated with duplex configuration, the network-side device can configure SRS resources on the uplink subbands configured in the downlink time units, or on the uplink time units. This provides more options for SRS resource locations, which helps reduce SRS transmission latency. 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 SRS transmission latency.

[0081] The reference signal described in the embodiments of the present application includes but is not limited to at least one of the following:

[0082] 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).

[0083] The association relationship between the reference signal and the SRS resource described in the embodiments of the present application includes but is not limited to at least one of the following:

[0084] 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.

[0085] The association relationship described in the embodiments 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 (such as beams).

[0086] 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.

[0087] 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.

[0088] 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 and the beam used by the MsgA sent on the MsgA resource are the same.

[0089] For example, by using SRS for uplink beam training, the SRS beam selected by the terminal can be used as the beam used for subsequently sending Msg A. Alternatively, the beam used for sending Msg A can also be used as the beam for sending SRS.

[0090] For another example, the association relationship between the MsgA PUSCH 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 MsgA PUSCH sent on the MsgA PUSCH resource are the same.

[0091] 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 MsgA PUSCH transmission can be used as the beam for SRS transmission.

[0092] Introducing SRS transmission in the Idle or Inactive state can be used for uplink beam management or uplink capacity enhancement of the terminal.

[0093] By introducing the association between SSB / CSI-RS and SRS resources, the terminal can perform uplink beam training before cell access, determine a more appropriate PRACH transmission beam, and improve PRACH reception reliability.

[0094] 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 PRACH capacity.

[0095] By introducing the association of multiple PRACH resources / MsgA resources / MsgA PUSCH resources with SRS resources, multiple PRACH / MsgA / MsgA PUSCH resource repetitions using the same SRS resources can be supported, thereby improving the reliability of PRACH / MsgA / MsgA PUSCH resource transmission.

[0096] The SSB described in the embodiment of the present application can 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.

[0097] 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.

[0098] In this 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.

[0099] It should be understood that the embodiments of the present application do not limit the use of SRS, and for example, it can be used for beam training or for terminal positioning. 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.

[0100] 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.

[0101] 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 the random access phase, making the configuration method of the SRS resource more flexible, and the duplex configuration can also be determined based on the uplink configuration information without introducing additional duplex configuration signaling overhead.

[0102] In some embodiments, the uplink configuration information can also be configured in the connected state. In other words, the embodiments of the present application can obtain the SRS resource configuration in the duplex mode in the connected state, making the configuration of the SRS resource more flexible, and the duplex configuration can also be determined based on the uplink configuration information without introducing additional duplex configuration signaling overhead.

[0103] In some embodiments, the terminal determining the duplex configuration according to the uplink configuration information may specifically include:

[0104] The terminal determines, according to the SRS resource in at least one downlink time unit, an uplink subband in the at least one downlink time unit;

[0105] 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.

[0106] Therefore, this embodiment clarifies that the uplink subband on at least one downlink time unit can be determined based on the SRS resources on at least one downlink time unit. After determining the uplink subband on at least one downlink time unit, the duplex configuration on at least one downlink time unit can be known.

[0107] 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, month.

[0108] For example, taking the downlink time unit as a downlink timeslot (DL slot) as an example, the terminal may determine an uplink subband (uplink subband) in the downlink timeslot through an SRS resource in the downlink timeslot.

[0109] 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.

[0110] 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.

[0111] It should be noted that SRS resources need to be mapped (or associated) to a 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 resource for uplink data transmission based on the selected reference signal. Taking the reference signal as an SSB as an example, the SRS resource needs 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 resource based on the selected SSB.

[0112] 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.

[0113] As shown in FIG7 , in 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.

[0114] In some embodiments, in each downlink time unit of 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 self-interference caused by simultaneous reception and transmission.

[0115] 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 guard interval.

[0116] 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 guard interval.

[0117] In some embodiments, the terminal determining the duplex configuration according to the uplink configuration information may specifically include:

[0118] The terminal determines, according to an SRS resource in at least one uplink time unit, a downlink subband in the at least one uplink time unit;

[0119] The SRS resource on the at least one uplink time unit includes at least one of the following:

[0120] Part or all of the SRS resources configured by the uplink configuration information;

[0121] Part or all of the SRS resources in the SRS resource set configured by the uplink configuration information.

[0122] Therefore, this embodiment clarifies that the downlink subband on at least one uplink time unit can be determined based on the SRS resources on at least one uplink time unit. After determining the downlink subband on at least one uplink time unit, the duplex configuration on the at least one uplink time unit can be known.

[0123] 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.

[0124] 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.

[0125] 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 self-interference caused by simultaneous reception and transmission.

[0126] Exemplarily, the SRS resource on at least one uplink time unit is valid, which can be understood as:

[0127] 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.

[0128] In some embodiments, the at least one SRS resource satisfies at least one of the following:

[0129] 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;

[0130] 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 if the preset conditions are met;

[0131] 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).

[0132] Specifically, this embodiment clarifies the conditions that must be met by at least one SRS resource where the guard interval is located, which is conducive to better utilization of SRS resources.

[0133] 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.

[0134] In some embodiments, at least one SRS resource that serves as a guard interval for a portion or all of the bandwidth may not be used for SRS transmission, or may not be used for SRS transmission if a preset condition is met. The preset condition can be understood as a condition where the transmission of the SRS does not interfere with the transmission of a downlink signal or downlink channel, or the interference is minimal.

[0135] In some embodiments, the preset condition includes but is not limited to at least one of the following:

[0136] The time domain interval between the SRS resource and the reference signal is less than or not greater than the first time threshold;

[0137] The frequency domain interval between the SRS resource and the reference signal is less than or not greater than the first frequency threshold;

[0138] There is a reference signal transmission in the remaining bandwidth outside the uplink sub-band;

[0139] A downlink common channel or a downlink common signal is transmitted in the remaining bandwidth outside the uplink sub-band;

[0140] There is reception of a reference signal in the remaining bandwidth outside the uplink sub-band;

[0141] A downlink common channel or a downlink common signal is received in the remaining bandwidth outside the uplink sub-band.

[0142] 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 SRS transmission on the reference signal or the downlink common channel or the downlink common signal.

[0143] Exemplarily, taking the downlink time unit as a downlink time slot (DL slot) as an example, as shown in FIG. 7 or FIG. 8 , the remaining bandwidth outside the uplink sub-band may include the bandwidth occupied by the guard interval and the downlink sub-band.

[0144] Optionally, the first time threshold may be agreed upon by a protocol, or configured by a network-side device.

[0145] Optionally, the first frequency threshold may be agreed upon by a protocol, or configured by a network-side device.

[0146] In some embodiments, the preset condition is pre-configured by the network side device, or the preset condition is agreed upon by a protocol.

[0147] 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 self-interference caused by simultaneous reception and transmission.

[0148] 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.

[0149] 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:

[0150] SRS resources present in uplink time units;

[0151] SRS resources exist in time units with flexible symbols;

[0152] SRS resources present in the uplink subband of the downlink time unit;

[0153] SRS resources existing in the uplink subband of the downlink time unit, and no reference signal resources existing in the downlink time unit;

[0154] An SRS resource exists on an uplink subband of a downlink time unit, and a reference signal resource exists on the downlink time unit;

[0155] SRS resources that are not in the uplink subband of the downlink time unit.

[0156] 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, reducing SRS transmission delay. Furthermore, by transmitting SRS on the uplink subband within the downlink time unit, system resource utilization can be improved.

[0157] 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).

[0158] 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.

[0159] In some embodiments, the SRS resource set configured by the uplink configuration information satisfies at least one of the following:

[0160] Includes different types of SRS resources;

[0161] Include SRS resources of the same type;

[0162] 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;

[0163] Mapped to different reference signal resources, for example, different SSB indexes, or different CSI-RS indexes, or different preambles, or different Msg A resource indexes, or different Msg A PUSCH resource indexes.

[0164] 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.

[0165] 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, thereby enabling more flexible SRS resource set configuration.

[0166] In some embodiments, the SRS resource set configured by the uplink configuration information is used for repeated transmission of the SRS. Optionally, the SRS resource set configured by the uplink configuration information is used for repeated transmission during an initial SRS transmission, or the SRS resource set configured by the uplink configuration information is used for repeated transmission during a retransmission of the SRS.

[0167] In some embodiments, the uplink configuration information is common configuration information, wherein the common configuration information is used to configure SRS resources on an uplink subband and SRS resources on a non-uplink subband, or the common configuration information is used to configure an SRS resource set on an uplink subband and an SRS resource set on a non-uplink subband. For example, the SRS resource on a non-uplink subband may be an SRS resource on an uplink time unit. For another example, the SRS resource on a non-uplink subband may be an SRS resource on a time unit containing flexible symbols.

[0168] That is, the same SSRS resource configuration (ie, a common SRS resource configuration) may be used to configure two possible types of SRS resources: SRS resources on a UL subband and SRS resources on a non-UL subband.

[0169] In some embodiments, the uplink configuration information is two independent pieces of configuration information, wherein the two independent pieces of configuration information are used to configure the SRS resources on the uplink subband and the SRS resources on the non-uplink subband, respectively, or the two independent pieces of configuration information are used to configure the SRS resource set on the uplink subband and the SRS resource set on the non-uplink subband, respectively. For example, the SRS resources on the non-uplink subband may be SRS resources on an uplink time unit. For another example, the SRS resources on the non-uplink subband may be SRS resources on a time unit containing flexible symbols.

[0170] 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 may be used to configure SRS resources on a UL subband, and another SRS resource configuration may be used to configure SRS resources on a non-UL subband.

[0171] 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:

[0172] At least two different SRS resources are independently associated with the reference signal, that is, at least two different SRS resources are independently mapped to the reference signal;

[0173] 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 to the reference signal;

[0174] 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;

[0175] At least two different types of SRS resources are associated with the reference signal, that is, at least two different types of SRS resources are mapped with the reference signal;

[0176] An SRS resource is not associated with a reference signal that overlaps with the SRS resource in the time domain.

[0177] For example, taking the reference signal as an SSB, 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 quickly as possible, for example, some SRS resources are in the uplink subband (UL subband) and some SRS resources are in the normal uplink bandwidth (UL band). In this way, 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 transmissions / repetitions with low latency.

[0178] 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 flexible slot are independently associated with the SSB resources.

[0179] For example, taking the reference signal as an SSB, at least two different types of SRS resources are independently associated with the reference signal. For example, an SRS resource present in a time slot with flexible symbols is associated with SSB 0, an SRS resource present in an uplink subband of a downlink time slot is associated with SSB 1, and an SRS resource present in an uplink subband not in a downlink time slot is associated with SSB 3. For another example, an SRS resource present in a time slot with flexible symbols is associated with an odd-numbered SSB, and an SRS resource present in an uplink subband of a downlink time slot is associated with an even-numbered SSB. In this example, a reference signal may be associated with at least two different types of SRS resources as quickly as possible, such as some SRS resources in an uplink subband (UL subband) and some SRS resources in a normal uplink bandwidth (UL band). This allows a group of SRS resources associated with the same reference signal to be selected that are more compact in time, facilitating the transmission / repetition of multiple SRSs with low latency.

[0180] For example, using an SSB as the reference signal, at least two different SRS resources are associated with the reference signal. For example, the SRS resources can be configured relative to the SSB resources, with some SRS resources being located in the uplink subband of the downlink slot and some SRS resources being located in a normal uplink slot or a flexible slot. The SSB and SRS are associated in a specific order, regardless of the slot in which the SRS is located. This reduces the complexity of associating the SSB with the SRS resources, as there is no need to distinguish between different types of SRS resources.

[0181] For example, taking the reference signal as SSB, at least two different SRS resources are associated with the reference signal together, for example, as follows: SRS resources are associated with SSBs in 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 between different types of SRS resources.

[0182] For example, taking the reference signal as an SSB, 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 between different types of SRS resources.

[0183] For example, using an SSB as the reference signal, the SRS resource is not associated with reference signals that overlap with it in the time domain. For example, if an SRS resource overlaps with a reference signal in the time domain, the SRS resource is not associated with the reference signal. For example, if an SRS resource on a subband appears in the same OFDM symbol as a reference signal, the SRS resource can be considered invalid. This can reduce interference with the reference signal.

[0184] In some embodiments, a mapping cycle, an association period, or an association pattern period between the SRS resource configured by the uplink configuration information and the reference signal is determined by at least one of the following methods:

[0185] Method 1: The mapping period, association period, or association pattern period between at least two different SRS resources and reference signals is independently determined;

[0186] Mode 2: The mapping cycle, association period, or association pattern period between at least two different types of SRS resources and reference signals are independently determined;

[0187] Mode 3: The mapping period, association period, or association pattern period between at least two different SRS resources and the reference signal are determined together;

[0188] Mode 4: The mapping period, association period, or association pattern period between at least two different types of SRS resources and reference signals are determined together;

[0189] Mode 5: The mapping period, association period, or association pattern period between the SRS resource and the reference signal is related to the period of the duplex configuration.

[0190] Optionally, for mode 1, mapping cycles or association periods or association pattern periods between different SRS resources and reference signals may be the same, or may be different.

[0191] Optionally, for mode 2, mapping cycles or association periods or association pattern periods between different types of SRS resources and reference signals may be the same, or may be different.

[0192] Optionally, for mode 3, the mapping cycle or association period or association pattern period between the at least two different SRS resources and the reference signal is a common value determined based on the mapping cycle or association period or association pattern period between all SRS resources and the reference signal.

[0193] 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 the mapping cycles or association periods or association pattern periods between all SRS resources and the reference signal.

[0194] Optionally, for mode 4, the mapping cycle or association period or association pattern period between the at least two different types of SRS resources and the reference signal is a common value determined based on the mapping cycle or association period or association pattern period between all types of SRS resources and the reference signal.

[0195] For example, when at least two different types of SRS resources are independently mapped to reference signals, the mapping cycle or association period or association pattern period between the at least two different types of SRS resources and the reference signal is the maximum value of the mapping cycle or association period or association pattern period between all types of SRS resources and the reference signal.

[0196] In some embodiments, a mapping cycle between SRS resources and reference signals is a time period during which all preconfigured reference signals with all indices can be mapped at least once.

[0197] In some embodiments, the association period between an SRS resource and a reference signal is the shortest time during which all preconfigured reference signals with all indices can be mapped at least once and is an integer multiple of the SRS period.

[0198] In some embodiments, the association pattern period between an SRS resource and a reference signal is an integer multiple of the association pattern period between the SRS resource and the reference signal, and is 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.

[0199] 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.

[0200] 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.

[0201] Therefore, in an embodiment of the present application, the network-side device can configure the terminal with SRS resources or SRS resource sets in duplex mode. Furthermore, the terminal can transmit SRS based on the SRS resources or SRS resource sets in duplex mode, thereby improving the utilization of system resources and reducing the transmission delay of 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. In this way, the network-side device does not need to perform duplex configuration through separate signaling, making the duplex configuration more flexible.

[0202] In addition, 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.

[0203] The SRS resource configuration method provided in the embodiments of the present application can be executed by a duplex configuration determination device, or a processing unit in the duplex configuration determination device for executing the SRS resource configuration method. In the embodiments of the present application, the duplex configuration determination device executing the SRS resource configuration method is used as an example to illustrate the duplex configuration determination device provided in the embodiments of the present application.
