It should be noted that in the embodiments 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.

[0044] In order to better understand the embodiments of the present application, the random access process related to the present application is described.

[0045] 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).

[0046] 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 radio 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 numbers of the preamble carried in MSG.2 is consistent with the number of the preamble sent by itself, 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, that is, the four-step random access is completed.

[0047] 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 includes information such as the random access preamble ID (RAPID), the temporary cell radio network temporary identity (TC-RNTI), and the 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 TC-RNTI-scrambled physical downlink control channel (PDCCH).

[0048] 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.3PUSCH 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.3PUSCH scheduling resources, so the network includes 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.3PUSCH, the UE considers that the contention resolution is successful. If they do not match, the contention resolution is considered unsuccessful.

[0049] If the contention resolution is unsuccessful, the UE reselects RACH resources, sends a physical random access channel (PRACH), and makes the next random access attempt.

[0050] In the two-step random access process (2-step RACH), the first step is that the UE sends MsgA to the network side. After receiving MsgA, the network side 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.

[0051] MsgA includes MsgA preamble and MsgA PUSCH. The preamble is sent on the RO for 2-stepRACH, 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.

[0052] In order to facilitate a better understanding of the embodiments of the present application, the duplex mode enhancement related to the present application is explained.

[0053] In 5G mobile communication systems, 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 of communication (mMTC). These scenarios put forward requirements for the system such as high reliability, low latency, large bandwidth, and wide coverage.

[0054] In NR, configuring full-duplex operation can significantly improve the delay and coverage performance of the Time Division Duplex (TDD) system. For example, subband non-overlapping full-duplex (subband non-overlapping Fullduplex), because the uplink subband and the downlink subband are non-overlapping, the self-interference is small, which can reduce transmission delay and enhance coverage.

[0055] For a downlink timeslot (DL slot), the network configures the downlink (DL) bandwidth part (Band Width Part, BWP) for the UE (by TDD uplink and downlink common configuration (tdd-UL-DL-ConfigurationCommon) or TDD uplink and downlink dedicated configuration (tdd-UL-DL-ConfigurationDedicated)), such as Figure 2 For an uplink (UL) time slot, the network configures the UE with a UL BWP (configured by TDD-UL-DL-ConfigurationCommon or TDD-UL-DL-ConfigurationDedicated), such as Figure 3 Time slot 4.

[0056] For a downlink timeslot (DL slot) (configured by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated), in a full duplex scenario, such as Figure 2 As shown, there are the following examples (cases):

[0057] Case 1: Configure DL BWP, such as slot 1;

[0058] Case 2: Configure DL BWP and uplink sub-band (UL sub-band), such as slot 2.

[0059] For an uplink timeslot (UL slot) (configured by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated), in a full duplex scenario, such as Figure 3 As shown, there are the following examples (cases):

[0060] Case 3: Configure UL BWP, such as slot 4;

[0061] Case 4: Configure UL BWP and downlink sub-band (DL sub band), such as slot5.

[0062] 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.

[0063] 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).

[0064] 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 on the network side at the same time can only be for different terminals.

[0065] Another exemplary duplex mode is: both the terminal side and the network side are full duplex, such as Figure 4 As shown, 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 performed simultaneously at different frequency domain positions.

[0066] 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, such as Figure 5shown.

[0067] 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.

[0068] In order to facilitate a better understanding of the embodiments of the present application, the configured granted physical uplink shared channel (CG PUSCH) in an idle state (Idle) or a deactivated state (Inactive) related to the present application is described.

[0069] At present, NR supports configuring CG PUSCH resources in the Radio Resource Control (RRC) deactivated state for small data transmission.

[0070] The configured CG PUSCH resources need to be mapped to the synchronization signal block (Synchronization Signal Block, SSB). The terminal selects an SSB that meets a certain reference signal received power (Reference Signal Received Power, RSRP) quality based on the measurement of the SSB, and determines the CG PUSCH resources for small data transmission based on the selected SSB.

[0071] In order to facilitate a better understanding of the embodiments of the present application, the problems solved by the present application are explained.

[0072] At present, duplex enhancement in the 5G stage mainly considers connected UEs, and the network side supports full-duplex and the UE side supports half-duplex.

[0073] In an embodiment of the present application, the duplex mode can be configured in an idle state (Idle) or a deactivated state (Inactive), or dynamically configured in a random access phase, or configured in a connected state. Specifically, the duplex configuration can be determined based on the configuration of an uplink data sharing channel resource or a set of uplink data sharing channel resources, without the need for separate signaling for duplex configuration, and the uplink data sharing channel can be transmitted in the duplex mode, thereby improving the utilization rate of the uplink data sharing channel resources and reducing the transmission delay of the uplink data sharing channel.

[0074] 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.

[0075] Figure 6 is a schematic flow chart of a method 200 for determining a duplex configuration according to an embodiment of the present application, such as Figure 6 As shown, the duplex configuration determination method 200 may include at least part of the following contents:

[0076] 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: uplink data sharing channel resources, a set of uplink data sharing channel resources; wherein the uplink configuration information is associated with the duplex configuration;

[0077] S220, the terminal receives the uplink configuration information from the network side device;

[0078] S230: The terminal determines a duplex configuration according to the uplink configuration information.

[0079] It should be understood that Figure 6 The steps or operations of the duplex configuration determination method 200 are shown, but these steps or operations are only examples. The embodiment of the present application may also perform other operations or Figure 6 Variations of the various operations in .

[0080] In an embodiment of the present application, under the duplex configuration determined based on the uplink configuration information, 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.

[0081] In an embodiment of the present application, the terminal can determine the duplex configuration based on the configuration of the uplink data sharing channel resource or the set of uplink data sharing channel resources, without the need for separate signaling to perform the duplex configuration. The duplex configuration is more flexible, and the duplex configuration is associated with the uplink data sharing channel resource. The uplink data sharing channel can be transmitted in the duplex mode, thereby improving the utilization rate of the uplink data sharing channel resources and reducing the transmission delay of the uplink data sharing channel.

[0082] The duplex configuration described in the embodiment of the present application may also be referred to as at least one of the following: enhanced duplex configuration, enhanced duplex mode, cross duplex (XDD), enhanced full duplex, enhanced full duplex mode. The embodiment of the present application is not limited to this.

[0083] The duplex configuration described in the embodiment of the present application may refer to: determining the uplink subband from the downlink time unit, or determining the downlink subband on the uplink time unit. Thus, duplex transmission of downlink and uplink can be realized on the downlink time unit, or duplex transmission of downlink and uplink can be realized on the uplink time unit.

[0084] The reference signal described in the embodiment of the present application includes but is not limited to at least one of the following:

[0085] 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).

[0086] The association relationship between the reference signal and the uplink data shared channel resource described in the embodiment of the present application includes but is not limited to at least one of the following:

[0087] The association relationship between SSB and uplink data sharing channel resources, the association relationship between CSI-RS and uplink data sharing channel resources, the association relationship between PRACH resources and uplink data sharing channel resources, the association relationship between MsgA resources and uplink data sharing channel resources, the association relationship between MsgA PUSCH resources and uplink data sharing channel resources, the association relationship between TRS resources and uplink data sharing channel resources, and the association relationship between SRS resources and uplink data sharing channel resources.

[0088] The association relationship described in the embodiment of the present application may also be referred to as a mapping relationship, which may be an equal relationship between two signals or channel resources in a certain sense.

[0089] 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.

[0090] In some embodiments, the uplink data sharing channel resources configured by the uplink configuration information are semi-static or configured grant (CG) resources. Optionally, the uplink data sharing channel resources configured by the uplink configuration information are CG PUSCH resources. Optionally, the CG PUSCH resources may include at least one of the following: CG PUSCH time-frequency resources, DMRS sequences, and DMRS ports.

[0091] In an embodiment of the present application, the uplink data sharing channel resources configured by the uplink configuration information may include: uplink data sharing channel resources directly configured by the uplink configuration information, or uplink data sharing channel resources in a set of uplink data sharing channel resources configured by the uplink configuration information.

[0092] In the embodiment of the present application, since the uplink data sharing channel resources configured by the uplink configuration information are semi-static or configured with a grant (CG) resource, the uplink data sharing channel resources configured by the uplink configuration information can be used in an idle state (Idle) or a deactivated state (Inactive), and the duplex configuration determined based on the uplink configuration information can also be used in an idle state (Idle) or a deactivated state (Inactive). That is, the present embodiment can support duplex configuration in an idle state (Idle) or a deactivated state (Inactive), thereby improving the resource utilization efficiency in an idle state (Idle) or a deactivated state (Inactive).

[0093] In some embodiments, the uplink configuration information can be configured in an idle state (Idle) or a deactivated state (Inactive), or the uplink configuration information can be dynamically configured in a random access phase. In other words, the embodiment of the present application can obtain the duplex configuration in an idle state (Idle) or a deactivated state (Inactive) or in a random access phase, and the duplex configuration is more flexible without introducing additional duplex configuration signaling.

[0094] 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 duplex configuration in a connected state, the duplex configuration is more flexible, and no additional duplex configuration signaling is required.

[0095] In some embodiments, the above S230 may specifically include:

[0096] The terminal determines, according to an uplink data shared channel resource on at least one downlink time unit, an uplink subband on the at least one downlink time unit;

[0097] The uplink data sharing channel resources on the at least one downlink time unit include at least one of the following: part or all of the uplink data sharing channel resources configured by the uplink configuration information, and part or all of the uplink data sharing channel resources in a set of uplink data sharing channel resources configured by the uplink configuration information.

[0098] This embodiment clarifies that the uplink subband on at least one downlink time unit can be determined based on the uplink data sharing channel resources on 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.

[0099] 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.

[0100] For example, taking the uplink data shared channel resource as the CG PUSCH resource and the downlink time unit as the downlink time slot (DL slot), the terminal can determine the uplink subband (uplink subband) in the downlink time slot through the CG PUSCH resource in the downlink time slot.

[0101] In some embodiments, the terminal determines part or all of physical resource blocks (PRBs) occupied by the uplink data sharing channel resources on the at least one downlink time unit as uplink subbands, wherein the uplink data sharing channel resources on the at least one downlink time unit are valid.

[0102] Exemplarily, the uplink data shared channel resource on at least one downlink time unit is valid, which can be understood as: satisfying the mapping relationship between the reference signal and the uplink data shared channel resource on at least one downlink time unit.

[0103] It should be noted that the uplink data sharing channel resources need to be mapped to the reference signal. The terminal selects the reference signal that meets a certain RSRP quality based on the measurement of the reference signal, and determines the uplink data sharing channel resources for uplink data transmission based on the selected reference signal. Taking the uplink data sharing channel resources as CG PUSCH resources and the reference signal as SSB as an example, the configured CG PUSCH resources need to be mapped to SSB. The terminal selects the SSB that meets a certain RSRP quality based on the measurement of the SSB, and determines the CG PUSCH resources for small data transmission based on the selected SSB.

[0104] For example, taking the uplink data shared channel resource as the CG PUSCH resource and the downlink time unit as the downlink time slot (DL slot), in all downlink time slots where the CG PUSCH resource appears, the PRB occupied by the CG PUSCH resource is considered to be configured as an uplink subband (uplink subband), and the CG PUSCH resource is considered to be valid.

[0105] Exemplarily, the uplink data shared channel resource is a CG PUSCH resource, and the downlink time unit is a downlink time slot, such as Figure 7 As shown, in the downlink time slot n, part of the PRBs occupied by the CG PUSCH resources (PRBs except the protection interval) are considered to be configured as an uplink subband, and the CG PUSCH resources are considered to be valid.

[0106] 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 uplink data sharing channel 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.

[0107] For example, the uplink data shared channel resource is a CG PUSCH resource, and the downlink time unit is a downlink time slot (DL slot). Figure 7 As shown, in the downlink time slot n, the entire bandwidth occupied by a CG PUSCH resource adjacent to the uplink subband is the guard interval.

[0108] For example, the uplink data shared channel resource is a CG PUSCH resource, and the downlink time unit is a downlink time slot (DL slot). Figure 8 As shown, in the downlink time slot n, part of the bandwidth occupied by a CG PUSCH resource adjacent to the uplink subband is the guard interval.

[0109] In some embodiments, the above S230 may specifically include:

[0110] The terminal determines, according to an uplink data shared channel resource on at least one uplink time unit, a downlink subband on the at least one uplink time unit;

[0111] The uplink data sharing channel resources on the at least one uplink time unit include at least one of the following: part or all of the uplink data sharing channel resources configured by the uplink configuration information, and part or all of the uplink data sharing channel resources in a set of uplink data sharing channel resources configured by the uplink configuration information.

[0112] This embodiment clarifies that the downlink subband on at least one uplink time unit can be determined based on the uplink data sharing channel resources on 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.

[0113] 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.

[0114] In some embodiments, the terminal determines part or all of the PRBs except the PRBs occupied by the uplink data sharing channel resources on the at least one uplink time unit as downlink subbands, wherein the uplink data sharing channel resources on the at least one uplink time unit are valid.

[0115] 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 uplink data sharing channel resource adjacent to the downlink subband is a guard interval. Specifically, the setting of the guard interval can suppress the self-interference generated by simultaneous reception and transmission.

[0116] Exemplarily, the uplink data sharing channel resources on at least one uplink time unit are valid, which can be understood as: satisfying a mapping relationship between a reference signal and the uplink data sharing channel resources on at least one uplink time unit.

[0117] In some embodiments, the at least one uplink data shared channel resource satisfies at least one of the following:

[0118] The mapping relationship between the reference signal and the uplink data shared channel resources is satisfied, and the uplink data shared channel is not used for sending;

[0119] The mapping relationship between the reference signal and the uplink data shared channel resources is satisfied, and the uplink data shared channel is not used to send the uplink data shared channel when the preset conditions are met;

[0120] The mapping relationship from the reference signal to the uplink data shared channel resources is not satisfied.

[0121] Specifically, this embodiment clarifies the conditions that at least one uplink data sharing channel resource where the guard interval is located must meet, which is conducive to better utilization of the uplink data sharing channel resources.

[0122] It should be noted that the uplink data sharing channel resources that satisfy the mapping relationship from the reference signal to the uplink data sharing channel resources can be considered valid; the uplink data sharing channel resources that do not satisfy the mapping relationship from the reference signal to the uplink data sharing channel resources can be considered invalid.

[0123] In some embodiments, the preset condition includes but is not limited to at least one of the following:

[0124] The time domain or frequency domain interval between the uplink data sharing channel resource and the reference signal is less than or not greater than the first threshold;

[0125] There is a reference signal transmission in the remaining bandwidth outside the uplink subband;

[0126] There is transmission of a downlink common channel or a downlink common signal in the remaining bandwidth outside the uplink sub-band;

[0127] There is reception of a reference signal in the remaining bandwidth outside the uplink subband;

[0128] The remaining bandwidth outside the uplink sub-band is used for receiving a downlink common channel or a downlink common signal.

[0129] For example, when a preset condition is met, the uplink data shared channel is not used to send, thereby avoiding interference of the sending of the uplink data shared channel with the sending of the reference signal or the downlink common channel or the downlink common signal.

[0130] For example, the random access uplink resource is a CG PUSCH resource, and the downlink time unit is a downlink time slot (DLslot). Figure 7 or Figure 8 As shown, the remaining bandwidth outside the uplink sub-band may include the bandwidth occupied by the guard interval and the downlink sub-band.

[0131] Optionally, the first threshold may be agreed upon by a protocol, or the first threshold may be configured by a network-side device.

[0132] In some embodiments, the preset condition is pre-configured by a network side instruction, or the preset condition is agreed upon by a protocol.

[0133] 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.

[0134] In an embodiment of the present application, in support of enhanced duplex mode, uplink data sharing channel resources may be allowed on an uplink subband of an additionally configured downlink time unit, so a new type of uplink data sharing channel resource may appear.

[0135] In some embodiments, the uplink data shared channel resources configured by the uplink configuration information include but are not limited to at least one of the following types:

[0136] Uplink data sharing channel resources existing in the uplink time unit;

[0137] Uplink data shared channel resources existing in time units with flexible symbols;

[0138] Uplink data shared channel resources present in the uplink subband of the downlink time unit;

[0139] An uplink data shared channel resource existing in an uplink subband of a downlink time unit, and no reference signal resource existing in the downlink time unit;

[0140] An uplink data shared channel resource existing on an uplink subband of a downlink time unit, and a reference signal resource existing on the downlink time unit;

[0141] Uplink data not in the uplink subband of the downlink time unit shares channel resources.

[0142] For example, taking the uplink data shared channel resource as a CG PUSCH resource, the time unit as a time slot, and the reference signal as an SSB as an example, the CG PUSCH resource configured by the uplink configuration information includes at least one of the following types:

[0143] CG PUSCH resources present in the uplink timeslot;

[0144] CG PUSCH resources existing in slots with flexible symbols;

[0145] CG PUSCH resources present in the uplink subband of the downlink timeslot;

[0146] CG PUSCH resources exist in the uplink subband of the downlink timeslot, and there are no SSB resources in the downlink timeslot;

[0147] CG PUSCH resources exist in the uplink subband of a downlink timeslot, and SSB resources exist in the downlink timeslot;

[0148] CG PUSCH resources that are not in the uplink subband of the downlink timeslot.

[0149] 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.

[0150] In some embodiments, the set of uplink data shared channel resources configured by the uplink configuration information satisfies at least one of the following:

[0151] Including different types of uplink data sharing channel resources;

[0152] Including uplink data sharing channel resources of the same type;

[0153] mapped to the same reference signal resource;

[0154] Mapped to different reference signal resources.

[0155] This embodiment clarifies the types of uplink data sharing channel resources in the set of uplink data sharing channel resources configured by the uplink configuration information and the reference signal resources to which the set of uplink data sharing channel resources is mapped, so that the set of uplink data sharing channel resources can be configured more flexibly.

[0156] In some embodiments, the set of uplink data sharing channel resources configured by the uplink configuration information is used for repeated transmission of the uplink data sharing channel. Optionally, the set of uplink data sharing channel resources configured by the uplink configuration information is used for repeated transmission during initial transmission of the uplink data sharing channel, or the set of uplink data sharing channel resources configured by the uplink configuration information is used for repeated transmission during retransmission of the uplink data sharing channel.

[0157] In some embodiments, the uplink configuration information is a common configuration information, wherein the common configuration information is used to configure the uplink data sharing channel resources on the uplink subband and the uplink data sharing channel resources on the non-uplink subband, or the common configuration information is used to configure the set of uplink data sharing channel resources on the uplink subband and the set of uplink data sharing channel resources on the non-uplink subband. For example, the uplink data sharing channel resources on the non-uplink subband may be the uplink data sharing channel resources on the uplink time unit. For another example, the uplink data sharing channel resources on the non-uplink subband may be the uplink data sharing channel resources on the time unit containing flexible symbols.

[0158] For example, taking the uplink data sharing channel resource as a CG PUSCH resource, the uplink configuration information is a common CG configuration. Specifically, the same CG configuration (i.e., a common CG configuration) is used to configure two possible types of CG PUSCH resources, namely: CG PUSCH resources on a UL subband and CG PUSCH resources on a non-UL subband.

[0159] In some embodiments, the uplink configuration information is two independent configuration information, wherein the two independent configuration information are used to configure the uplink data sharing channel resources on the uplink subband and the uplink data sharing channel resources on the non-uplink subband, or the two independent configuration information are used to configure the set of uplink data sharing channel resources on the uplink subband and the set of uplink data sharing channel resources on the non-uplink subband. For example, the uplink data sharing channel resources on the non-uplink subband may be the uplink data sharing channel resources on the uplink time unit. For another example, the uplink data sharing channel resources on the non-uplink subband may be the uplink data sharing channel resources on the time unit containing flexible symbols.

[0160] For example, taking the uplink data sharing channel resource as a CG PUSCH resource, the uplink configuration information is two independent CG configurations. Specifically, the CG PUSCH resource on the UL subband is configured with one CG configuration; and the CG PUSCH resource on the non-UL subband is configured with another CG configuration.

[0161] In some embodiments, the association relationship between the uplink data shared channel resource configured by the uplink configuration information and the reference signal satisfies at least one of the following:

[0162] At least two different uplink data shared channel resources are independently associated with the reference signal;

[0163] At least two different types of uplink data shared channel resources are independently associated with the reference signal;

[0164] At least two different uplink data shared channel resources are associated with the reference signal;

[0165] At least two different types of uplink data shared channel resources are associated with the reference signal;

[0166] The uplink data shared channel resource is not associated with the reference signal that overlaps with it in the time domain.

[0167] Exemplarily, taking the uplink data shared channel resource as a CG PUSCH resource and the reference signal as an SSB as an example, at least two different uplink data shared channel resources are independently associated with the reference signal, for example, as follows: CG PUSCH resource 1 is associated with SSB 0, CG PUSCH resource 2 is associated with SSB 1, CG PUSCH resource 3 is associated with SSB 0, and CG PUSCH resource 4 is associated with SSB 1. In this example, a reference signal may be associated with at least two CG PUSCH resources as soon as possible, for example, some CG PUSCH resources are on the uplink subband (UL subband) and some CG PUSCH resources are in the normal uplink bandwidth (UL band), so that a group of CG PUSCH resources that are more compact in time and associated with the same reference signal can be selected, which is conducive to completing multiple CG PUSCH transmissions / repetitions with low latency.

[0168] Exemplarily, taking the uplink data sharing channel resources as CG PUSCH resources and the reference signal as SSB as an example, at least two different types of uplink data sharing channel resources are independently associated with the reference signal, for example, as follows: the CG PUSCH resources configured on the uplink subband of the downlink slot and the uplink CG PUSCH resources on the uplink slot or the flexible slot are independently associated with the SSB resources.

[0169] Exemplarily, taking the uplink data sharing channel resource as the CG PUSCH resource and the reference signal as the SSB as an example, at least two different types of uplink data sharing channel resources are independently associated with the reference signal, for example, as follows: the CG PUSCH resource existing in the time slot with flexible symbols is associated with SSB 0, the CG PUSCH resource existing in the uplink subband of the downlink time slot is associated with SSB 1, and the CG PUSCH resource not in the uplink subband of the downlink time slot is associated with SSB 3; for another example, the CG PUSCH resource existing in the time slot with flexible symbols is associated with the odd-numbered SSB, and the CG PUSCH resource existing in the uplink subband of the downlink time slot is associated with the even-numbered SSB. In this example, a reference signal may be associated with at least two different types of CG PUSCH resources as soon as possible, such as some CG PUSCH resources in the uplink subband (UL subband) and some CG PUSCH resources in the normal uplink bandwidth (UL band), so that a group of CG PUSCH resources that are more compact in time and associated with the same reference signal can be selected, which is conducive to completing multiple CG PUSCH transmissions / repetitions with low latency.

[0170] Exemplarily, taking the uplink data sharing channel resource as CG PUSCH resource and the reference signal as SSB as an example, at least two different uplink data sharing channel resources are associated with the reference signal together, for example, as follows: relative to the SSB resource, the CG PUSCH resource is configured, some CG PUSCH is on the uplink subband of the downlink slot, and some CG PUSCH resources are in the normal uplink slot or flexible slot, and the SSB and CG PUSCH association is performed in a certain order, without distinguishing which slot the CG PUSCH is on. The association complexity of SSB to CG PUSCH resources can be reduced, and there is no need to distinguish different types of CG PUSCH resources.

[0171] Exemplarily, taking the uplink data shared channel resource as the CG PUSCH resource and the reference signal as the SSB as an example, at least two different uplink data shared channel resources are associated with the reference signal together, for example, as follows: the CG PUSCH resource is associated with the SSB in the order of identification, such as CG PUSCH resource 0 is associated with SSB 0, CG PUSCH resource 1 is associated with SSB 1, CG PUSCH resource 2 is associated with SSB 2, CG PUSCH resource 3 is associated with SSB 3, CG PUSCH resource 4 is associated with SSB 4, CG PUSCH resource 5 is associated with SSB 0, CG PUSCH resource 6 is associated with SSB 1, and CG PUSCH resource 7 is associated with SSB 2. In this example, the complexity of associating the reference signal with the CG PUSCH resource can be reduced, and there is no need to distinguish different types of CG PUSCH resources.

[0172] Exemplarily, taking the uplink data shared channel resource as a CG PUSCH resource and the reference signal as an SSB as an example, at least two different types of uplink data shared channel resources are associated with the reference signal together, for example, as follows: CG PUSCH resources are associated with SSBs in the order of identification, such as CG PUSCH resource 0 is associated with SSB 0, CG PUSCH resource 1 is associated with SSB 1, CG PUSCH resource 2 is associated with SSB 2, CG PUSCH resource 3 is associated with SSB 3, and CG PUSCH resource 4 is associated with SSB 4. In this example, the complexity of associating the reference signal with the CG PUSCH resource can be reduced, and there is no need to distinguish different types of CG PUSCH resources.

[0173] Exemplarily, taking the uplink data sharing channel resource as the CG PUSCH resource and the reference signal as the SSB as an example, the uplink data sharing channel resource is not associated with the reference signal that overlaps with it in the time domain, for example, as follows: If the CG PUSCH resource overlaps with a reference signal in the time domain, the CG PUSCH resource is not associated with the reference signal. For example, for a CG PUSCH resource on a certain subband, if a reference signal appears on the same OFDM symbol, the CG PUSCH resource can be considered invalid. This can reduce interference to the reference signal.

[0174] In some embodiments, a mapping cycle or an association period or an association pattern period between an uplink data shared channel resource and a reference signal configured by the uplink configuration information satisfies at least one of the following:

[0175] At least two different uplink data sharing channel resources are independently determined;

[0176] At least two different types of uplink data sharing channel resources are independently determined;

[0177] At least two different uplink data sharing channel resources are determined together;

[0178] At least two different types of uplink data shared channel resources are determined together;

[0179] Related to the period of duplex configuration.

[0180] Exemplarily, at least two different uplink data sharing channel resources independently determine at least one of the following: a mapping cycle between the uplink data sharing channel resources and the reference signal, an association period between the uplink data sharing channel resources and the reference signal, and an association pattern period between the uplink data sharing channel resources and the reference signal.

[0181] For example, in the case where at least two different uplink data sharing channel resources are independently determined, a mapping cycle or an association period or an association pattern period is a maximum value among values ​​determined for all uplink data sharing channel resources.

[0182] Exemplarily, at least two different types of uplink data sharing channel resources independently determine at least one of the following: a mapping cycle between the uplink data sharing channel resources and the reference signal, an association period between the uplink data sharing channel resources and the reference signal, and an association pattern period between the uplink data sharing channel resources and the reference signal.

[0183] For example, when at least two different types of uplink data sharing channel resources are independently determined, a mapping cycle or an association period or an association pattern period is a maximum value among values ​​determined by all uplink data sharing channel resource types.

[0184] Exemplarily, at least two different uplink data sharing channel resources together determine at least one of the following: a mapping cycle between the uplink data sharing channel resources and the reference signal, an association period between the uplink data sharing channel resources and the reference signal, and an association pattern period between the uplink data sharing channel resources and the reference signal.

[0185] For example, in the case where at least two different uplink data shared channel resources are determined together, a mapping cycle or an association period or an association pattern period determines a common value for all uplink data shared channel resources.

[0186] Exemplarily, at least two different types of uplink data sharing channel resources together determine at least one of the following: a mapping cycle between the uplink data sharing channel resources and the reference signal, an association period between the uplink data sharing channel resources and the reference signal, and an association pattern period between the uplink data sharing channel resources and the reference signal.

[0187] For example, in the case where at least two different types of uplink data sharing channel resources are determined together, a mapping cycle or an association period or an association pattern period determines a common value for all uplink data sharing channel resource types.

[0188] In some embodiments, the mapping cycle between the uplink data shared channel resources and the reference signal is the time during which all pre-configured reference signals with all indexes can be mapped at least once.

[0189] In some embodiments, the association period between the uplink data shared channel resources and the reference signal is the shortest time during which all preconfigured reference signals with all indexes can be mapped at least once and is an integer multiple of the uplink data shared channel period.

[0190] In some embodiments, the association pattern period between the uplink data sharing channel resource and the reference signal is an integer multiple of the association pattern period between the uplink data sharing channel resource and the reference signal, and the time for mapping the uplink data sharing channel resource and the reference signal to form a pattern. Optionally, the time for mapping the uplink data sharing channel resource and the reference signal to form a pattern is less than or does not exceed a preset time.

[0191] Therefore, in an embodiment of the present application, the terminal can determine the duplex configuration based on the configuration of the uplink data sharing channel resources (such as CG PUSCH resources) or the set of uplink data sharing channel resources (a set of CG PUSCH resources), without the need for separate signaling for duplex configuration. The duplex configuration is more flexible, and the duplex configuration is associated with the uplink data sharing channel resources (such as CGPUSCH resources). The uplink data sharing channel (such as CG PUSCH) can be transmitted in the duplex mode, thereby improving the utilization rate of the uplink data sharing channel resources and reducing the transmission delay of the uplink data sharing channel (such as CG PUSCH).

[0192] In an embodiment of the present application, flexible duplex configuration can be supported in an idle state (Idle) / deactivated state (Inactive), and the mapping of reference signals to uplink data sharing channel resources (such as CG PUSCH resources) reduces the transmission delay of the uplink data sharing channel (such as CG PUSCH). Uplink data sharing channel resources (such as CG PUSCH resources) or a set of uplink data sharing channel resources (a set of CG PUSCH resources) can be dynamically configured based on the uplink configuration information, which can improve resource utilization to a greater extent.

[0193] The duplex configuration determination method provided in the embodiment of the present application may be executed by a duplex configuration determination device, or a processing unit in the duplex configuration determination device for executing the duplex configuration determination method. In the embodiment of the present application, the duplex configuration determination device executing the duplex configuration determination method is taken as an example to illustrate the duplex configuration determination device provided in the embodiment of the present application.
