[0058] In order to better understand the technical solution of this application, the following contents are first introduced:

[0059] Subbands non-overlapping Full duplex

[0060] Sub-band non-overlapping full-duplex can improve transmission delay and enhance coverage.

[0061] For a downlink time slot (DL slot), the DL slot can be configured by the time division multiplexing uplink and downlink common configuration (tdd-UL-DL-ConfigurationCommon) or the time division multiplexing uplink and downlink dedicated configuration (tdd-UL-DL-ConfigurationDedicated), and the network side device configures the DL bandwidth part (Bandwidth Part, BWP) for the UE in the DL slot. For an uplink time slot (UL slot), the UL slot can be configured by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated, and the network side device configures the UL BWP for the UE in the UL slot. For example, see Figure 1b and Figure 1c Time slots 1 and 4 shown;

[0062] For the full duplex scenario, there is the following example:

[0063] Case 1: Configure DL BWP, that is, slot 1;

[0064] Case 2: Configure DL BWP and UL sub-band, i.e. slot 2;

[0065] Case 3: Configure UL BWP, that is, slot 4;

[0066] Case 4: Configure UL BWP and DL sub-band (SB), i.e. slot 5;

[0067] For sub band full duplex (SBFD) operation, one SBFD subband consists of one resource block (RB) or a set of consecutive RBs with the same transmission direction.

[0068] 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).

[0069] See also Figure 1d :

[0070] For the first mode, the base station and the UE can only send or receive at one time.

[0071] For the second mode, the gNB side supports full-duplex, the gNB can send and receive at the same time, and the UE side can only use half-duplex mode, that is, it can only send or receive at a time.

[0072] For the third mode, both the gNB and UE sides support full-duplex, and the gNB and UE can transmit and receive at the same time.

[0073] See also Figure 1e : For full-duplex on the UE side, a larger guard band (GB) may be required (the GB on the UE side is larger than the GB of the base station FD) to suppress self-interference.

[0074] 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.

[0075] CG PUSCH transmission in idle / inactive state

[0076] Currently, LTE / NR supports configuring PUSCH resources (i.e., CG PUSCH resources) scheduled by configured grant in RRC Idle / inactive state for small data transmission (SDT).

[0077] The configured CG PUSCH resources need to have a predefined mapping relationship with the synchronization signal block (Synchronization Signal Block, SSB). The terminal selects an SSB that meets a certain reference signal receiving 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.

[0078] The uplink transmission resource selection method provided in the embodiment of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0079] First, the following contents are explained:

[0080] To simplify the description, the following two full-duplex modes are defined, namely

[0081] Network full-duplex operation: full-duplex is applied on the network side and half-duplex is applied on the UE side.

[0082] Terminal full-duplex operation: that is, full-duplex is applied on the network side and full-duplex is applied on the UE side.

[0083] The UE side is half-duplex, that is, it can only receive DL or send UL signals or channels in one time unit.

[0084] Full-duplex on the UE side means receiving DL and sending UL signals or channels simultaneously in one time unit.

[0085] The network full-duplex mode can achieve the purpose of enhancing coverage, reducing transmission delay, and improving resource utilization efficiency. The terminal full-duplex mode can improve DL (UL) throughput while achieving the above gains.

[0086] Usually, a guard band is reserved between UL transmission and DL transmission, for example, guard band is reserved to achieve frequency isolation and reduce self-interference. Usually, the self-interference elimination capability of UE is weaker than that of gNB. For simultaneous transmission and reception on UE side, the reserved GB is larger than that on gNB side, that is, more reserved PRBs are required as guard bands.

[0087] As shown in the figure, Figure 3a (a) is the subband and GB configuration of full duplex on the network side, that is, the network configures the time-frequency resources of the UL subband and DL subband (and or GB). In the UL subband, the network receives the UL channel or signal of the served UE, and in the DL subband, the network sends the DL channel or signal to the served UE. DL transmission will cause self-interference to UL reception.

[0088] Figure 3a (b) is the full-duplex subband configuration on the UE side. The network configures the time-frequency resources of the UL subband and DL subband (and or GB) for the UE. The UL transmission of the UE will cause self-interference to the DL reception.

[0089] Different UEs may have different capabilities, so the GBs that need to be reserved may be different.

[0090] See also Figure 2 The embodiment of the present application provides an uplink transmission resource selection method, the execution subject of the method is a terminal, and the method includes:

[0091] Step 201: The terminal selects a CG PUSCH resource according to first information;

[0092] The first information includes at least one of the following:

[0093] (1) The measured value of SSB or the first reference signal;

[0094] That is, the CG PUSCH resource / type is selected based on the measurement of SSB or other reference signals (such as Channel State Information-Reference Signal (CSI-RS)).

[0095] (2) The amount of data to be sent;

[0096] That is, the CG PUSCH resource / type is selected according to the size of the data to be sent;

[0097] (3) Frequency domain unit type information;

[0098] The frequency domain information may include bandwidth information and / or carrier information;

[0099] It should be noted that the above-mentioned CG PUSCH resources are configured by the network side (for example, through the system information block (SIB) or other high-level signaling (for example, RRC release, etc.), and the CG PUSCH resources may include multiple types, such as in the UL subband or UL symbol of the DL symbol or in the UL slot or in the flexible symbol. The terminal selects the CG PUSCH resource for uplink data transmission based on the reference basis of (1) to (3) above.

[0100] The above CG PUSCH resources include:

[0101] (1) A first type of CG PUSCH resource, which is configured in a UL subband; the first type of CG PUSCH resource may be denoted as type A;

[0102] (2) The second type of CG PUSCH resources, the second type of CG PUSCH resources are configured in UL time domain units (such as UL time slots and UL symbols); the first type of CG PUSCH resources can be recorded as type B.

[0103] For networks and terminals that support SBFD, there are usually four types of time domain units (symbols or slots):

[0104] like Figure 3b As shown:

[0105] (1)DL time domain unit;

[0106] (2) DL time domain unit configured with UL SB;

[0107] (3) UL time domain unit configured with DL SB;

[0108] (4) UL time domain unit;

[0109] Furthermore, there may be:

[0110] (1) Flexible time domain units are not configured for UL and DL directions;

[0111] The network can configure this time domain unit to be a valid resource for transmitting CG PUSCH.

[0112] (2) Configure the flexible time domain unit of UL SB;

[0113] The network may configure the UL SB of the time domain unit to be a valid resource for transmitting the CG PUSCH.

[0114] (3) Configure flexible time domain units for DL ​​SB;

[0115] The network may configure the resources outside the DL SB of the time domain unit to be effective resources for transmitting the CG PUSCH.

[0116] (4) Other situations are not excluded, for example, GB (guard band) is not an effective resource for transmitting CG PUSCH.

[0117] For a configured CG PUSCH resource (set), there may be two types of configurations, namely

[0118] Case 1: CG PUSCH resources (sets) are configured in a UL subband (can be in UL time domain resources, i.e., UL time slots or symbols, can be in DL / flexible symbols), for example, type A, i.e., CG PUSCH resource type A;

[0119] Case 2: The CG PUSCH resource (set) is configured in one UL / flexible time domain unit (no DL subband is configured), for example, type B, i.e., CG PUSCH resource type B;

[0120] For the sake of clarity, the following describes the uplink transmission resource selection method by taking the UL time domain unit as an example. It is worth noting that the flexible time domain unit is also applicable to the uplink transmission resource selection method, which will not be described in detail in the embodiments of the present application.

[0121] In an embodiment of the present application, the terminal selects a CG PUSCH resource according to at least one of the measured value of the SSB or the first reference signal, the amount of data to be sent, and the frequency domain unit type information, wherein the terminal can select the first type of CG PUSCH resource configured in the UL subband, or select the second type of CG PUSCH resource configured in the UL time domain unit. In this way, the terminal can flexibly select the CG PUSCH resource configured in the UL subband or the CG PUSCH resource configured in the UL time domain unit according to the specific situation, which can provide more CG PUSCH transmission opportunities, and is beneficial to transmission delay and coverage.

[0122] In a possible implementation manner, when the first information includes a measurement value of an SSB or a first reference signal, the terminal selects a CG PUSCH resource according to the first information, including:

[0123] (1) When the measured value is greater than the first threshold, the terminal selects the first type of CG PUSCH resource or the second type of CG PUSCH resource; at this time, the terminal can first select the first type of CG PUSCH resource;

[0124] (2) When the measured value is greater than or equal to the second threshold and less than the first threshold, the terminal selects the second type of CG PUSCH resource;

[0125] Among them, the first threshold is greater than the second threshold, the second threshold is greater than or equal to the third threshold, and the third threshold is the minimum value of the measurement value of the SSB or the first reference signal when the terminal performs small data transmission (SDT).

[0126] The above first threshold, second threshold, and third threshold can be configured by the network side or predefined by the protocol.

[0127] By the above (1) and (2), selecting the appropriate type of uplink transmission resource based on the measurement value of the SSB or the first reference signal can provide more CG PUSCH transmission opportunities, while considering reducing cross-link interference and self-interference, so as to improve transmission delay and coverage.

[0128] The above measured value can include RSRP, Reference Signal Received Quality (RSRQ), or Received Signal Strength Indication (RSSI). For the sake of clear description below, an example is given with the measured value specifically being RSRP.

[0129] Optionally, for different CG PUSCH types, the network can configure different thresholds. CG PUSCH type A is configured with threshold M, and CG PUSCH type B is configured with threshold N, where G <= N < M. The threshold G is one of the conditions for enabling SDT, that is, it can be the threshold G of the RSRP for DL path loss reference.

[0130] Optionally, the threshold G can be not configured. When the threshold G is not configured, when the terminal performs SDT, the terminal first selects the first type of CG PUSCH resource, and then selects the second type of CG PUSCH resource.

[0131] The above measured value can include the RSRP for DL path loss reference. The steps of selecting the CG PUSCH resource based on the measured value can refer to the following description.

[0132] When the RSRP of the DL path loss reference measured by the UE is less than or equal to threshold M and greater than threshold N, the UE selects CGPUSCH type B, for example, CG PUSCH configured in the UL slot.

[0133] When the RSRP of the DL path loss reference measured by the UE is greater than the threshold M, the UE can select CG PUSCH type A or CG PUSCH type B, and the network can configure the UE to give priority to CG PUSCH type A, such as CG PUSCH configured in the UL SB. This can reduce latency and improve UL transmission coverage. It can also reduce interference to other UEs.

[0134] The above SDT enable conditions can be

[0135] (1) The amount of all UL data waiting to be transmitted with SDT enabled is less than the configured sdt-DataVolumeThreshold;

[0136] (2) The RSRP referenced by the DL path loss is higher than the configured threshold G, where G <= N <M;

[0137] (3) SDT resources are available and effective;

[0138] Specifically, see Figure 3b , the configured CG PUSCH resources (sets) can be further divided according to whether they overlap with SSB:

[0139] (1) Configured CG PUSCH resource (set) / Configuration 1: The CG PUSCH resource (set) is configured in a UL SB in a DL time domain unit where an SSB / common DL channel exists, i.e., it overlaps with the SSB / common DL channel time domain. At this time, the uplink transmission of one UE will interfere with the reception of SSB of other UEs, i.e., cross-link interference. If the UE uses the SSB to measure or decode the common DL channel, it will also receive self-interference.

[0140] (2) Configured CG PUSCH resource (set) / Configuration 2: The CG PUSCH resource (set) is configured in a UL SB in a DL time domain unit where there is no SSB / common DL channel, i.e., it does not overlap with the SSB / common DL channel time domain. In this case, the uplink transmission of one UE will interfere with the reception of DL channels or signals of other UEs, i.e., PDCCH, PDSCH, CSI-RS, etc.

[0141] (3) Configured CG PUSCH resource (set) / Configuration 3: The CG PUSCH resource (set) is configured in the UL SB of one UL time domain unit, and the interference situation is similar to Configuration 2.

[0142] (4) Configured CG PUSCH resource (set) / Configuration 4: The CG PUSCH resource (set) is configured in one UL time domain unit, and there is no cross-link interference.

[0143] The RSRP referenced by the DL path loss can be SSB or CSI-RS.

[0144] If the SS-RSRP of a certain SSB measured by the UE is greater than RSRP-ThresholdSSB, the SSB greater than RSRP-ThresholdSSB is selected, otherwise any SSB is selected (the SS-RSRP of multiple SSBs is greater than RSRP-ThresholdSSB).

[0145] When selecting CSI-RS, the CSI-RSRP of the CSI-RS will be compared with the parameter RSRP-ThresholdSSB. If the CSI-RSRP of a certain CSI-RS is greater than RSRP-ThresholdCSI-RS, the CSI-RS greater than RSRP-ThresholdCSI-RS is selected.

[0146] The UE determines the transmit power of the CG PUSCH based on the DL path loss reference.

[0147] For one of the conditions for SDT enable, when the RSRP referenced by the DL path loss is higher than the configured threshold, CG-SDT will be activated;

[0148] The network can configure the UE to select different CG PUSCH resource types for CG-SDT transmission according to different path losses, that is, determine the selected CG PUSCH resource type by measuring the RSRP / RSRQ / RSSI of the SSB or CSI-RS.

[0149] For example, if the RSRP referenced by the DL path loss measured by the UE is high, it indicates that the UE is close to the gNB and the transmit power of the CG PUSCH is also low. The cross-link interference to other UE's DL channels / signals, such as SSB and public control channels, is also low, and the self-interference to the measurement reception of its own DL channels / signals at the same time is also low.

[0150] If the RSRP of the path loss reference measured by the UE is low, it indicates that the UE is far from the gNB, and the transmission power of the CG PUSCH is also high. At this time, the cross-link interference on the DL channels / signals of other UEs is also high. This is not conducive to other UEs receiving key information such as SSB and other key DL control channels, as well as the reception of DL data channels. In severe cases, it will affect the access and normal communication of other UEs. The self-interference on the measurement and reception of the DL channels / signals of the UE itself at the same time is also relatively high, which will also have a negative impact. Therefore, for the CG PUSCH configured in the UL sub-band, it is beneficial for the UE with a higher RSRP of the path loss reference to send the CG PUSCH.

[0151] Optionally, referring to Figure 3c , the network can configure that at least one CG PUSCH located in the UL symbol and one CG PUSCH of the UL SB are associated with one SSB. CG PUSCH 1-1 and CG PUSCH 1-2 can be different CG PUSCH configurations or the same CG PUSCH configuration. As Figure 3c shown, this can reduce the transmission delay of the CG PUSCH and improve the coverage of the CG PUSCH. As shown in the figure. The UE can select to send the CG PUSCH in the UL SB or transmit the CG PUSCH on the UL symbol according to the above criteria. The network can configure the UE to preferentially select to send the CG PUSCH in the UL SB.

[0152] Among them, CG PUSCH 1-1 and CG PUSCH 1-2 can be based on different configurations or the same configuration

[0153] CG PUSCH 2-1 and CG PUSCH 2-2 can be based on different configurations or the same configuration

[0154] Furthermore, multiple SSBs can be associated with at least one CG PUSCH located in the UL symbol and one CGPUSCH of the UL SB.

[0155] In a possible implementation manner, when the first information includes the data volume to be sent, the terminal selects the CG PUSCH resource according to the first information, including:

[0156] (1) When the data volume to be sent is less than or equal to the fourth threshold, the terminal selects the first type of CGPUSCH resource;

[0157] (2) When the data volume to be sent is greater than the fourth threshold, the terminal selects the second type of CG PUSCH resource.

[0158] The above fourth threshold can be configured by the network side or predefined by the protocol.

[0159] Specifically, for different CG PUSCH types, the size of the data carried may be different, and the terminal selects the corresponding CG PUSCH type according to the actual data size.

[0160] The network can configure one sdt-DataVolumeThreshold per CG PUSCH type;

[0161] The threshold for Type A CG PUSCH is sdt-DataVolumeThreshold A;

[0162] The threshold of Type B CG PUSCH is sdt-DataVolumeThreshold B (the threshold of Type B CG PUSCH is optional);

[0163] sdt-DataVolumeThreshold A can be smaller than sdt-DataVolumeThreshold B.

[0164] When the amount of UL data waiting to be transmitted on all RBs (radio bearers) is greater than the configured sdt-DataVolumeThreshold A and less than sdt-DataVolumeThreshold B, the UE selects Type B CGPUSCH

[0165] Similarly, the network can configure a number of physical resource blocks (PRBs), or transport resource blocks (TBSs), or a code rate threshold P for each CG PUSCH type, and determine the selected CG PUSCH type based on the above parameters to be sent.

[0166] In a possible implementation manner, when the first information includes frequency domain unit type information, the terminal selects a CG PUSCH resource according to the first information, including:

[0167] (1) When the first indication information corresponding to the target frequency domain unit indicates that the target frequency domain unit only supports the first type of CGPUSCH resources, the terminal selects the first type of CG PUSCH resources; it should be noted that the "only" here refers only to the first type and the second type of CG PUSCH resources, and does not exclude the support of other transmission resources or other types of PUSCH resources;

[0168] (2) When the first indication information corresponding to the target frequency domain unit indicates that the target frequency domain unit only supports the second type of CGPUSCH resources, the terminal selects the second type of CG PUSCH resources; it should be noted that the "only" here refers only to the first type and the second type of CG PUSCH resources, and does not exclude the support of other transmission resources or other types of PUSCH resources;

[0169] (3) When the first indication information corresponding to the target frequency domain unit indicates that the target frequency domain unit supports the first type and the second type of CG PUSCH resources, the terminal preferentially selects one type of CG PUSCH resource according to a preset rule or a network indication; optionally, if the preset rule is met, the terminal can switch from one type of CG PUSCH resource to another type of CG PUSCH resource.

[0170] The target frequency domain unit is determined according to the frequency domain unit type information, and the first indication information is information obtained by the terminal from the network side, for example, through SIB or other high-level signaling (such as RRCRelease, etc.).

[0171] The above-mentioned target frequency domain unit refers to a frequency domain unit configured with CG PUSCH resources. The terminal determines the type of CG PUSCH resources supported by the target frequency domain unit based on the first indication information corresponding to the target frequency domain unit obtained from the network side, and then selects the CG PUSCH resources.

[0172] By implementing the above (1) to (3), the selection of appropriate types of uplink transmission resources based on the frequency domain unit type information can provide more CG PUSCH transmission opportunities, which is beneficial to transmission delay and coverage.

[0173] The frequency domain unit may be a band or a carrier, and correspondingly the first indication information is information indication specific to the band or carrier.

[0174] For the above (1) and (2), the first indication information indicates that the target frequency domain unit only supports a certain type of CGPUSCH resource, and the terminal selects the CG PUSCH resource of this type accordingly. For the above (3), the first indication information indicates that the target frequency domain unit supports multiple types of CG PUSCH resources, and the terminal preferentially selects one type of CG PUSCH resource based on preset rules or network instructions. Optionally, if the preset rules are met, the terminal can switch from one type of CG PUSCH resource to another type of CG PUSCH resource.

[0175] The preset rules include at least one of the following:

[0176] (1) When the transmit power of the terminal is less than the fifth threshold, the terminal selects the first type of CG PUSCH resources; when the transmit power of the terminal is greater than or equal to the fifth threshold, the terminal selects the second type of CG PUSCH resources;

[0177] That is, the network can configure a reference transmit power threshold for the UE. When the transmit power of the UE is less than the threshold, the UE selects CG PUSCH type A. When the transmit power of the UE is greater than or equal to the threshold, the UE switches to CG PUSCH type B, thereby reducing the impact of self-interference and / or cross-link interference.

[0178] (2) When the frequency interval between the terminal's uplink transmission and downlink reception is greater than the sixth threshold, the terminal selects the first type of CG PUSCH resources; when the frequency interval between the terminal's uplink transmission and downlink reception is less than or equal to the sixth threshold, that is, the resource is not a valid CG PUSCH resource, the terminal selects other first type of CG PUSCH resources that meet the preset requirements, or selects the second type of CG PUSCH resources.

[0179] That is, the frequency interval (gap) between UL transmission and DL reception. When the gap between UL transmission and DL reception is greater than the threshold, the UE selects CG PUSCH type A. When the gap between UL transmission and DL reception is less than the threshold, the resource is not a valid CGPUSCH resource, and the UE selects other CG PUSCH type A that meets the preset requirements or selects CG PUSCH type B.

[0180] Optionally, the terminal may select CG PUSCH resources according to the UE type;

[0181] If the UE capability does not support SBFD, the network can configure the UE to only allow the use of CG PUSCH located in the UL time domain unit when selecting CG PUSCH, for example, CG PUSCH resource / type B.

[0182] About CG PUSCH switching:

[0183] The network may configure, for a UE, for a CG PUSCH type A associated with an SSB n, i.e., the UE selects SSB n, if for a time t1, the CG PUSCH type A overlaps with another SSB m or a common DL channel (possibly associated with SSB n), and the UE uses the SSB m for measurement or decoding of the common DL channel, the network may configure one of the following:

[0184] (1) When the predefined principle is met, the UE selects CG PUSCH type A; the predefined principle refers to the above preset rules and is not repeated here.

[0185] (2) The UE switches to CG PUSCH type B to reduce the impact of self-interference.

[0186] The network can configure, for a UE, for CG PUSCH type A, when there is a time domain overlapping DL scheduling, the network can configure one of the following:

[0187] (1) When the predefined principle is met, the UE selects CG PUSCH type A; the predefined principle refers to the above preset rules and is not repeated here.

[0188] (2) The UE switches to CG PUSCH type B to reduce the impact of self-interference.

[0189] Alternatively, see Figure 3d to Figure 3g , this application also provides a method for determining the validity of CG PUSCH resources:

[0190] like Figure 3d As shown, if a CG PUSCH partially overlaps with the UL subband and the DL time domain unit, then the CGPUSCH is an invalid CG PUSCH;

[0191] like Figure 3e As shown, if a CG PUSCH partially overlaps with the UL subband and the UL time domain unit, then the CGPUSCH is a valid CG PUSCH;

[0192] like Figure 3f As shown, the network can indicate that if the frequency resource interval between a CG PUSCH resource or part of the resource and the GB is less than the preconfigured value, the CG PUSCH is an invalid CG PUSCH;

[0193] like Figure 3g As shown, if a CG PUSCH resource or part of the resources overlaps with a GB, then the CG PUSCH is an invalid CG PUSCH;

[0194] In a possible implementation, the method further includes:

[0195] In the case where the terminal selects the first type of CG PUSCH resources, if the first condition is met, the terminal switches to the second type of CG PUSCH resources;

[0196] The first condition includes at least one of the following:

[0197] (1) All SDTs fail within the first preset time period;

[0198] Optionally, the network may configure a timer for SDT detection failure for each CG PUSCH type;

[0199] For CG PUSCH type A: timer K for SDT detection failure;

[0200] For CG PUSCH type B: Timer L for SDT detection failure;

[0201] If the UE prefers CG PUSCH resource / type A, the UE switches to CGPUSCH resource / type B when the following conditions are met:

[0202] If the SDT detection failure timer K times out, that is, timer K expires or all SDTs fail within a configured period of time;

[0203] Through the above (1), by configuring the timer for SDT detection failure, whether the timer has timed out is used to determine whether all SDTs within the first preset time period have failed. If the timer has timed out, the first type of CG PUSCH resource is switched to the second type of CG PUSCH resource, so that the terminal can switch to a more appropriate CG PUSCH resource, ensuring the use of appropriate CGPUSCH resources for uplink transmission.

[0204] (2) The number of repeated transmissions on the first type of CG PUSCH resources reaches a first preset number of transmissions.

[0205] Optionally, the network may configure a CG-PUSCH retransmission timer (CG-PUSCH-RetransmissionTimer) for each CG-PUSCH type, for example:

[0206] CG-PUSCH type A configures CG-PUSCH-RetransmissionTimer A;

[0207] CG-PUSCH type B configures CG-PUSCH-RetransmissionTimer B;

[0208] If the UE sends a CG-PUSCH type A, the UE automatically retransmits the CG-PUSCH type A before RetransmissionTimer A expires.

[0209] Optionally, if the UE sends a CG-PUSCH type A, after RetransmissionTimer A expires, the UE switches to CG PUSCH resource / type B.

[0210] Through the above (2), by configuring the CG-PUSCH retransmission timer, whether the CG-PUSCH retransmission timer has timed out is used to determine whether the number of repeated transmissions on the first type of CG PUSCH resource has reached the first preset number of transmissions. If the CG-PUSCH retransmission timer has timed out, indicating that the number of repeated transmissions has reached the first preset number of transmissions, the second type of CG PUSCH resource is switched to enable the terminal to switch to a more appropriate CG PUSCH resource, thereby avoiding the terminal occupying too much time on one type of CG PUSCH resource, which is beneficial to improving the transmission delay of the terminal and ensuring the use of appropriate CG PUSCH resources for uplink transmission.

[0211] In a possible implementation, the method further includes:

[0212] When the second condition is met, the terminal performs the SDT transmission process based on RACH; or, when the second condition is met, the terminal declares SDT failure and enters the connected state through random access;

[0213] The second condition includes at least one of the following:

[0214] (1) All SDTs fail within the second preset duration, and random access (RA) resources with random access small data transmission (RA-SDT) are configured;

[0215] That is, if the SDT detection failure timer L times out, and if the RA resource set with RA-SDT is configured, the UE performs the SDT transmission process based on RACH, or declares SDT failure and enters the connected state through random access;

[0216] Through the above (1), by configuring a timer for SDT detection failure, whether all SDTs within the second preset time length have failed is determined by whether the timer has timed out. If the timer has timed out, the terminal executes the SDT transmission process based on RACH; or, the terminal declares that the SDT has failed, and enters the connection state through random access, so that when the selected CG PUSCH resource is inappropriate, the terminal can perform SDT through RACH, or directly choose to enter the connection state, so as to avoid the terminal occupying too much time on one type of CG PUSCH resource, which is beneficial to improving the transmission delay of the terminal and ensuring that uplink transmission can be performed.

[0217] (2) The number of retransmission times reaches the second preset retransmission number on all CG PUSCH resources;

[0218] That is, if both CG-PUSCH-RetransmissionTimer A and CG-PUSCH-RetransmissionTimer B expire, the UE performs the RACH-based SDT transmission procedure, or declares the SDT to fail and enters the connected state through random access;

[0219] Through the above (2), by configuring the CG-PUSCH retransmission timer, it is judged whether the number of retransmission times on all types of CG PUSCH resources reaches the second preset retransmission number according to whether all CG-PUSCH retransmission timers expire. If all CG-PUSCH retransmission timers expire, indicating that the number of retransmission times on all types of CG PUSCH resources reaches the second preset retransmission number, then the terminal performs the RACH-based SDT transmission procedure; or the terminal declares the SDT to fail and enters the connected state through random access, enabling the terminal to perform SDT through RACH or directly select to enter the connected state when the selected CG PUSCH resource is inappropriate, which is beneficial to improving the transmission delay of the terminal and ensuring that uplink transmission can be performed.

[0220] (3) The time advance TA corresponding to all types of CG PUSCH resources is invalid.

[0221] If different CG PUSCH types are mapped to different measurement signal (such as SSB) sets, then the TA validity judgment for different CG PUSCH types may be different. The TA validity may verify different measurement signal (such as SSB) sets for different CG PUSCH resource types. At this time, the calculated TA change magnitudes may be different, and thus the TA validity may also be different.

[0222] Through the above (3), it is judged whether the TA corresponding to all types of CG PUSCH resources is valid. If the TA corresponding to all types of CG PUSCH resources is invalid, then the terminal performs the RACH-based SDT transmission procedure; or the terminal declares the SDT to fail and enters the connected state through random access, enabling the terminal to perform SDT through RACH or directly select to enter the connected state when the selected CG PUSCH resource is inappropriate, which is beneficial to improving the transmission delay of the terminal and ensuring that uplink transmission can be performed.

[0223] The TA validity satisfies the following conditions:

[0224] 1. The RSRP values of the stored DL path loss reference and the current DL path loss reference are valid.

[0225] 2. Compared with the stored DL path loss reference RSRP, the change of the currently calculated DL path loss reference RSRP value does not exceed a predefined threshold.

[0226] 3. A predefined timer is running, for example (a timer for timing alignment:

[0227] CG-SDT-TimeAlignmentTimer)

[0228] If the UE selects CG PUSCH resource / type A, the UE switches to CG PUSCH resource / type B when the following conditions are met:

[0229] If the TA used by the terminal for sending on CG PUSCH resource A is invalid, but the TA used for sending on CG PUSCH resource B is valid.

[0230] Optionally, if the corresponding TA is invalid for all CG PUSCH resource types, the UE performs a RACH-based SDT transmission process.

[0231] Optionally, if the corresponding TA is invalid for all CG PUSCH resource types, the UE executes the declaration of SDT failure and attempts random access to enter the connected state.

[0232] In some other embodiments, the network may configure CG PUSCH resources / type A and CG PUSCH resources / type B to use different transmit powers. Typically, the transmit power of CG PUSCH resources / type B is greater than the transmit power of CG PUSCH resources / type A.

[0233] In some other implementations, the network may configure CG PUSCH resource type A and CG PUSCH resource type B to be associated with different reference signal resources (such as SSB).

[0234] The terminal associates multiple reference signal resources (such as SSB) in CG PUSCH resource type A. The network can predefine or configure a threshold. If the measured value of any one or more measurement metrics (such as SS-RSRP) is less than the threshold, the UE switches from CG PUSCH resource / type A to CG PUSCH resource / type B.

[0235] That is, if the measurement value (such as SS-RSRP) of a certain measurement metric of the terminal on the reference signal resource (such as SSB) associated with CG PUSCH resource A is less than or not greater than a predefined or network configured threshold.

[0236] Furthermore, the network can configure the UE to perform a RACH-based SDT transmission process if the measurement value of a certain measurement metric (such as SS-RSRP) of the terminal on the reference signal resources (such as SSB) associated with all CG PUSCH resources is less than or not greater than a predefined or network-configured threshold.

[0237] Optionally, if the measurement value (such as SS-RSRP) of a certain measurement metric of the terminal on the reference signal resources (such as SSB) associated with all CG PUSCH resources is less than or not greater than a predefined or network configured threshold, the UE declares SDT failure and attempts random access to enter the connected state.

[0238] In some other implementations, the network configuration for each CG-PUSCH resource type may include at least one of the following configuration information:

[0239] (1) Time domain offset (timeDomainOffset);

[0240] (2) Time Domain Allocation (timeDomainAllocation);

[0241] (3) Frequency Domain Allocation;

[0242] (4) Antenna Port;

[0243] (5)DMRS sequence initialization (DMRS-SeqInitialization);

[0244] (6) precoding and number of layers (precodingAndNumberOfLayers);

[0245] (7) srs-resource indicator (srs-ResourceIndicator);

[0246] (8) Modulation and Coding Scheme (MCS) and Transport Block Size (TBS) (mcsAndTBS);

[0247] (9) Frequency Hopping Offset (frequencyHoppingOffset);

[0248] (10) path loss reference index (pathlossReferenceIndex);

[0249] (12) cg-SDT-SSB-Subset;

[0250] (13)sdt SSB mapped to each CG-PUSCH (sdt-SSB-PerCG-PUSCH);

[0251] (14) Sdt open-loop power control parameter P0 (sdt-P0-PUSCH);

[0252] (15) sdt open-loop power control parameter Alpha (sdt-Alpha);

[0253] (16) sdt-DMRS-Ports;

[0254] (17)sdt-DMRS-Sequences (sdt-NrofDMRS-Sequences).

[0255] The uplink transmission resource selection method provided in the embodiment of the present application may be performed by an uplink transmission resource selection device. In the embodiment of the present application, the uplink transmission resource selection device performing the uplink transmission resource selection method is taken as an example to illustrate the uplink transmission resource selection device provided in the embodiment of the present application.

[0256] See also Figure 4 The embodiment of the present application provides an uplink transmission resource selection device, which can be applied to a terminal, including:

[0257] A selection module 401, configured for a terminal to select a CG PUSCH resource according to first information;

[0276] The target frequency domain unit is determined according to the frequency domain unit type information, and the first indication information is information obtained by the terminal from the network side;
