For a better understanding of the technical solution of the present application, the following description will be given first:

Sub-band non-overlapping full duplex (Subbands non-overlapping Full duplex)

Sub-band non-overlapping full duplex may improve transmission delay and enhance coverage.

For a downlink slot (DL slot), the DL slot may be configured by a time division multiplexing uplink-downlink common configuration (tdd-UL-DL-ConfigurationCommon) or a time division multiplexing uplink-downlink dedicated configuration (tdd-UL-DL-ConfigurationDedicated), the network side device configures a DL partial Bandwidth (BWP) for the UE in the DL slot, and for an uplink slot (UL slot), the UL slot may be configured by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated, and the network side device configures a UL BWP for the UE in the UL slot. See for example slots 1 and 4 shown in fig. 1b and 1 c;

For the and full duplex scenario, there is the following example (case):

case 1, configuring DL BWP, namely slot 1;

case 2, configuring DL BWP and UL sub band, namely slot 2;

case 3, configuring UL BWP, namely slot 4;

case 4, configuring UL BWP and DL sub-band (SB), namely slot5;

for sub-band full duplex (sub band Full duplex, SBFD) operation, one SBFD sub-band consists of 1 Resource Block (RB) or one contiguous set of RBs with the same transmission direction.

The gNB uses SBFD operational time units (e.g., slots or symbols), which may be referred to as SBFD time units (e.g., slots or symbols).

See fig. 1d:

for the first mode, the base station and the UE can only transmit or receive at one time.

For the second mode, the gNB side supports full duplex, and gNB can transmit and receive simultaneously, and the UE side can only adopt a half duplex mode, namely, can only transmit or receive at one time.

For the third mode, the gNB and the UE side both support full duplex, and the gNB and the UE can receive and transmit simultaneously.

Referring to fig. 1e, for UE-side full duplex, a larger Guard Band (GB) may be required (UE-side GB is larger than that of base station FD) for suppressing self-interference.

For a communication device, self-interference may be caused by simultaneous UL reception and DL transmission. In order to guarantee the transmission in the interfered direction, the communication device needs to have self-interference cancellation capability, such as reserving guard bands between the receiving band and the transmitting band, but this reduces the throughput of the UE.

Idle state (Idle) inactive state? CG PUSCH transmission in inactive) state

Currently, PUSCH resources (i.e., CG PUSCH resources) scheduled by configured grant are supported in RRC Idle/active state in LTE/NR for small data Transmission (SMALL DATA Transmission, SDT).

The configured CG PUSCH resource needs to have a predefined mapping relation with a synchronous signal block (Synchronization Signal Block, SSB), the terminal selects SSB meeting the quality of certain reference signal received Power (REFERENCE SIGNAL RECEIVING Power, RSRP) according to the measurement of the SSB, and the CG PUSCH resource used for small data transmission is determined according to the selected SSB.

The uplink transmission resource selection method provided by the embodiment of the application is described in detail below through some embodiments and application scenarios thereof with reference to the accompanying drawings.

The following will be explained first:

For simplicity of description, two full duplex modes are defined, namely

Network full duplex operation, i.e. full duplex is applied on the network side and half duplex is applied on the UE side.

And the terminal full duplex operation, namely the network side applies full duplex and the UE side applies full duplex.

UE side half duplex, i.e. can only receive DL or transmit UL signals or channels in one time unit.

UE-side full duplex, i.e. receiving DL and transmitting UL signals or channels simultaneously in one time unit.

The network full duplex mode can achieve the purposes of enhancing coverage, reducing transmission delay and improving resource utilization efficiency. The terminal full duplex mode can improve DL (UL) throughput while obtaining the above gain.

Guard bands, e.g., guard bands, are typically reserved between UL and DL transmissions to achieve frequency isolation to reduce self-interference. The self-interference cancellation capability of the UE is generally weaker than that of the gNB side, and for simultaneous transceiving of the UE side, the GB to be reserved is larger than that of the gNB side, i.e. more reserved PRBs are required as guard bands.

As shown, fig. 3a (a) is a full duplex subband and GB configuration on the network side, i.e., the network configures the time-frequency resources of the UL subband and DL subband (and or GB). In the UL sub-band, the network receives UL channels or signals for served UEs, and in the DL sub-band, the network transmits DL channels or signals for served UEs. DL transmissions may self-interfere with UL reception.

Fig. 3a (b) is a UE-side full duplex subband configuration, where the network configures UL and DL subbands (and or GB) time-frequency resources for the UE, and UL transmission by the UE may cause self-interference to DL reception.

The capabilities of different UEs may be different and thus the GB that needs to be reserved may be different.

Referring to fig. 2, an embodiment of the present application provides a method for selecting uplink transmission resources, where an execution body of the method is a terminal, and the method includes:

Step 201, selecting CG PUSCH resources by the terminal according to the first information;

Wherein the first information comprises at least one of:

(1) A measurement of SSB or first reference signal;

I.e. CG PUSCH resources/types are selected based on SSB or other reference signal measurements, e.g. channel state Information reference signal (CHANNEL STATE Information-REFERENCE SIGNAL, CSI-RS).

(2) The amount of data to be transmitted;

Namely selecting CG PUSCH resources/types according to the size of data to be transmitted;

(3) Frequency domain unit type information;

the frequency domain information may include bandwidth (band) information and/or carrier information;

It should be noted that, the CG PUSCH resources are configured by the network side (for example, indicated by a system information block (system information block, SIB) or other higher layer signaling (for example, RRCRELEASE, etc.), and the CG PUSCH resources may include multiple types, for example, CG PUSCH resources for uplink data transmission in UL subbands or UL symbols of DL symbols or in UL slots or in flexible symbols.

The CG PUSCH resources include:

(1) CG PUSCH resources of a first type, the CG PUSCH resources of the first type being configured in the UL subband;

(2) CG PUSCH resources of a second type, which are allocated in UL time domain units (e.g., UL slots and UL symbols), which may be denoted as type B.

For SBFD supported networks and terminals, there are typically 4 time domain unit (symbol or slot) types

As shown in fig. 3 b:

(1) DL time domain units;

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

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

(4) UL time domain units;

Further, there may be:

(1) Flexible time domain units of UL and DL directions are not configured;

the network may configure the time domain unit to be a valid resource for transmitting CG PUSCH.

(2) Configuring a flexible time domain unit of the UL SB;

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

(3) Configuring a flexible time domain unit of a DL SB;

The network may configure that resources other than DL SBs of the time domain unit are resources for efficient transmission of CG PUSCH.

(4) Other cases do not exclude that for example GB (guard band) is not a valid resource for transmitting CG PUSCH.

For a configured CG PUSCH resource (set), there may be a class 2 configuration scenario, i.e

Case 1 CG PUSCH resources (set) are configured in one UL subband (may be in UL time domain resources, i.e. UL slots or symbols, may be in DL/flexible symbols), e.g. type a, i.e. CG PUSCH resource type a;

Case 2 CG PUSCH resources (set) are configured in one UL/flexible time domain unit (no DL subbands are configured), e.g. type B, CG PUSCH resource type B;

For clarity of description, the uplink transmission resource selection method will be described below by taking UL time domain units as an example. It should be noted that the flexible time domain unit is also suitable for the uplink transmission resource selection method, and the embodiments of the present application are not repeated.

In the embodiment of the present application, the terminal selects CG PUSCH resources according to at least one of SSB or a measured value of a first reference signal, a data amount to be transmitted, and frequency domain unit type information, where the terminal may select CG PUSCH resources of a first type configured in a UL subband or CG PUSCH resources of a second type configured in a UL time domain unit. Therefore, the terminal can flexibly select CG PUSCH resources configured in the UL sub-band or CG PUSCH resources configured in the UL time domain unit according to specific conditions, more CG PUSCH transmission opportunities can be provided, and transmission delay and coverage are facilitated.

In a possible implementation manner, in a case where the first information includes a measured value of the SSB or the first reference signal, the terminal selects CG PUSCH resources according to the first information, including:

(1) Under the condition that the measured value is larger than a first threshold, the terminal selects the first type CG PUSCH resource or the second type CG PUSCH resource;

(2) Under the condition that the measured value is larger than or equal to a second threshold and smaller than the first threshold, the terminal selects CG PUSCH resources of a second type;

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 SSB or the measured value of the first reference signal when the terminal performs the small data transmission SDT.

The first threshold, the second threshold, and the third threshold may be configured by a network side or predefined by a protocol.

By implementing selection of the uplink transmission resource of the appropriate type based on the SSB or the measured value of the first reference signal in the above (1) and (2), more CG PUSCH transmission opportunities can be provided, and simultaneously, reduction of cross-link interference and self-interference is considered, so as to achieve improvement of transmission delay and coverage.

The above measurement values may include RSRP, reference signal Quality (RSRQ) or received signal strength Indication (RECEIVED SIGNAL STRENGTH Indication, RSSI), and are specifically illustrated as RSRP for clarity of description.

Alternatively, the network may configure different thresholds (threshold) for different CG PUSCH types, CG PUSCH type a configuring threshold M, CG PUSCH type B configuring threshold N, where G < = N < M. The threshold G is one of conditions for SDT enable (enable), i.e. the threshold G of RSRP that can be a DL path loss reference.

Alternatively, the threshold G may not be configured. When the threshold G is not configured, the terminal first selects CG PUSCH resources of the first type and then selects CG PUSCH resources of the second type when the terminal performs SDT.

The above measurement values may include RSRP of DL path loss reference, and the step of selecting CG PUSCH resources based on the measurement values may be described below.

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 CG PUSCH type B, for example, CG PUSCH configured in UL slot.

When the RSRP of the DL path loss reference measured by the UE is greater than threshold M, the UE may select CG PUSCH type a or CG PUSCH type B, and the network may configure the UE to preferentially select CG PUSCH type a, for example, CG PUSCH configured at UL SB. This can reduce latency and improve coverage of UL transmissions. And simultaneously, the interference to other UE can be reduced.

The SDT enable condition may be that

(1) All UL data amounts waiting for transmission to enable SDT are less than configured SDT-DataVolumeThreshold;

(2) The RSRP of the DL path loss reference is above a configured threshold G, where G < = N < M;

(3) The SDT resources are effectively available;

Specifically, with continued reference to fig. 3b, the configured CG PUSCH resources (sets) may be further partitioned according to whether or not they overlap SSBs:

(1) The configured CG PUSCH resources (set)/configuration 1: the CG PUSCH resources (set) are configured in one DL time domain unit where SSB/common DL channels exist, i.e. are time domain overlapping with SSB/common DL channels. At this time, the uplink transmission of one UE may interfere with the reception of SSBs of other UEs, i.e., cross-link interference. The UE also receives self-interference if it uses the SSB to measure or decode the common DL channel.

(2) The configured CG PUSCH resources (set)/configuration 2: the CG PUSCH resources (set) are configured in one DL time domain unit where there is no SSB/common DL channel, i.e. not overlapping with the SSB/common DL channel time domain. At this time, the uplink transmission of one UE may interfere with the reception of DL channels or signals of other UEs, i.e., PDCCH, PDSCH, CSI-RS, etc.

(3) Configuration CG PUSCH resources (set)/configuration 3 CG PUSCH resources (set) configured at UL SB of one UL time domain unit, interference situation is similar to configuration 2.

(4) The configured CG PUSCH resources (set)/configured 4:cg PUSCH resources (set) are configured in one UL time domain unit, where there is no cross-link interference.

The RSRP of the DL path loss reference may be SSB or CSI-RS.

If the UE measures that the SS-RSRP of a certain SSB is greater than RSRP-ThresholdSSB, then SSB greater than RSRP-ThresholdSSB is selected, otherwise any SSB is selected (the SS-RSRP of multiple SSBs is greater than RSRP-ThresholdSSB).

In selecting the CSI-RS, the CSI-RSRP of the CSI-RSs is compared with the parameter RSRP-ThresholdSSB, and if the CSI-RSRP of one of the CSI-RSs is larger than the RSRP-ThresholdCSI-RS, the CSI-RSs larger than the RSRP-ThresholdCSI-RS are selected.

And the UE determines the sending power of the CG PUSCH according to the DL path loss reference.

For one of the conditions of SDT enable, when the RSRP of the DL path loss reference is higher than the configured threshold, CG-SDT is activated;

The network can configure the UE to select different CG PUSCH resource types according to different path loss for CG-SDT transmission, namely, the selected CG PUSCH resource types are determined by measuring RSRP/RSRQ/RSSI of SSB or CSI-RS.

For example, if the RSRP of the DL path loss reference measured by the UE is higher, the characterizing UE is closer to the gNB, and the transmission power for CG PUSCH is also lower. DL channels/signals, e.g. SSB, to other UEs, the common control channel cross-link interference is also low, and the self-interference received by the measurement of the DL channels/signals at the same time is also low.

If the RSRP of the path loss reference measured by the UE is lower, the distance between the UE and the gNB is characterized, and the sending power of the CG PUSCH is higher. At this time, DL channel/signal cross-link interference to other UEs is also high. This is disadvantageous for other UEs to receive the key information such as SSB and other key DL control channels, and the reception of DL data channels, and may affect access and normal communication of other UEs in severe cases. The self-interference received from the measurement of the DL channel/signal itself at the same time is also relatively high and can have a negative impact. Therefore, for CG PUSCH configured in UL subband, it is beneficial for UE with higher RSRP for the path loss reference to transmit CG PUSCH.

Alternatively, referring to fig. 3c, the network may be configured such that one SSB associates at least one CG PUSCH at UL symbol and one CG PUSCH at UL SB. CG PUSCH 1-1 and CG PUSCH 1-2 may be different CG PUSCH configurations or the same CG PUSCH configuration, as shown in fig. 3c, so that CG PUSCH transmission delay may be reduced, and CG PUSCH coverage may be improved. As shown. The UE may select the transmit CG PUSCH at UL SB or the transmit CG PUSCH on UL symbol according to the criteria described above. The network may configure the UE to prefer to send CG PUSCH at UL SB.

Wherein CG PUSCH 1-1, CG PUSCH 1-2 can be based on different configurations or the same configuration

CG PUSCH 2-1, CG PUSCH 2-2 may be based on different configurations or the same configuration

Further, the plurality of SSBs may associate at least one CG PUSCH at a UL symbol and one CG PUSCH at a UL SB.

In a possible implementation manner, in a case that the first information includes an amount of data to be transmitted, the terminal selects CG PUSCH resources according to the first information, including:

(1) Under the condition that the data quantity to be transmitted is smaller than or equal to a fourth threshold, the terminal selects a CG PUSCH resource of a first type;

(2) And under the condition that the data quantity to be transmitted is larger than a fourth threshold, the terminal selects the CG PUSCH resource of the second type.

The fourth threshold may be predefined by the network side configuration or protocol.

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.

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

The threshold of the Type A CG PUSCH is sdt-DataVolumeThreshold A;

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

sdt-DataVolumeThreshold A may be less than sdt-DataVolumeThreshold B.

When the amount of UL data waiting for transmission on all RBs (radio bearers) is greater than sdt-DataVolumeThreshold A configured and less than sdt-DataVolumeThreshold B, the UE selects Type B CG PUSCH

Similarly, the network may configure one physical resource block (Physical Resource Block, PRB) number per CG PUSCH type, or transmission resource block (Transport Resource Block, TBS), or threshold P of code rate, and determine the selected CG PUSCH type according to the above parameters to be transmitted.

In a possible implementation manner, in a case that the first information includes frequency domain unit type information, the terminal selects CG PUSCH resources according to the first information, including:

(1) When the first indication information corresponding to the target frequency domain unit indicates that the target frequency domain unit supports only the first type of CG PUSCH resource, the terminal selects the first type of CG PUSCH resource, wherein the 'only' is only for the first type and the second type of CG PUSCH resource, and other transmission resources or other types of PUSCH resources are not excluded;

(2) When the first indication information corresponding to the target frequency domain unit indicates that the target frequency domain unit supports only the CG PUSCH resources of the second type, the terminal selects the CG PUSCH resources of the second type;

(3) And if the first indication information corresponding to the target frequency domain unit indicates that the target frequency domain unit supports the CG PUSCH resources of the first type and the second type, the terminal preferentially selects one type of CG PUSCH resources according to a preset rule or network indication, and optionally, if the preset rule is met, the terminal can be switched from one type of CG PUSCH resources to the other type of CG PUSCH resources.

The target frequency domain unit is determined according to the frequency domain unit type information, and the first indication information is information acquired by the terminal from the network side, for example, indicated by SIB or other high-layer signaling (e.g., RRCRELEASE, etc.).

The target frequency domain unit refers to a frequency domain unit configured with CG PUSCH resources, and the terminal determines the type of the CG PUSCH resources supported by the target frequency domain unit based on first indication information corresponding to the target frequency domain unit obtained from the network side, so as to select the CG PUSCH resources.

The uplink transmission resources of the proper types are selected based on the frequency domain unit type information through the steps (1) - (3), more CG PUSCH transmission opportunities can be provided, and transmission delay and coverage are facilitated.

The frequency domain unit may be a band or carrier (carrier), and the first indication information is a band or carrier specific information indication, respectively.

And (3) indicating that the target frequency domain unit supports a plurality of types of CG PUSCH resources by the first indication information, and at the moment, the terminal preferentially selects one type of CG PUSCH resource based on a preset rule or network indication. Alternatively, if a preset rule is satisfied, the terminal may switch from one type of CG PUSCH resource to another type of CG PUSCH resource.

The preset rule comprises at least one of the following:

(1) Under the condition that the transmission power of the terminal is smaller than a fifth threshold, the terminal selects the CG PUSCH resource of the first type, and under the condition that the transmission power of the terminal is larger than or equal to the fifth threshold, the terminal selects the CG PUSCH resource of the second type;

that is, the network may configure the UE with a reference transmit power threshold, and when the transmit power of the UE is less than the threshold, the UE selects CG PUSCH type a. When the UE's transmit power is greater than or equal to the threshold, then the UE switches CG PUSCH type B, thereby reducing the impact of self-interference and/or cross-link interference.

(2) Under the condition that the frequency interval between uplink transmission and downlink reception of the terminal is larger than a sixth threshold, the terminal selects a first type of CG PUSCH resource, and under the condition that the frequency interval between uplink transmission and downlink reception of the terminal is smaller than or equal to the sixth threshold, namely, the resource is not an effective CG PUSCH resource, the terminal selects other first type of CG PUSCH resources meeting the preset requirement, or selects a second type of CG PUSCH resource.

I.e., the frequency interval (gap) of 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 smaller than the threshold, the resource is not an effective CG PUSCH resource, and the UE selects other CG PUSCH types a or CG PUSCH types B meeting the preset requirement.

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

if the UE capability does not support SBFD, the network may configure the UE to only allow use of CG PUSCH in UL time domain units when selecting CG PUSCH, e.g., CG PUSCH resources/type B.

Regarding CG PUSCH handover:

The network may configure that for one UE, CG PUSCH type a associated with one SSB n, i.e. the UE selects SSB n, if for one time t1 CG PUSCH type a overlaps with another SSB m or common DL channel (possibly associated with SSB n), and the UE uses this SSB m to measure or decode the common DL channel, the network may configure one of:

(1) When the predefined rule is met, the UE selects CG PUSCH type A, and the predefined rule refers to the preset rule and is not repeated here.

(2) The UE switches CG PUSCH type B, thereby reducing the impact of self-interference.

The network may be configured such that for a UE, for CG PUSCH type a, there is a time domain overlapping DL schedule, the network may configure one of:

Optionally, referring to fig. 3d to fig. 3g, the application further provides a method for judging the validity of CG PUSCH resources:

as shown in fig. 3d, if one CG PUSCH is partially overlapped with the UL subband and DL time domain unit, the CG PUSCH is an invalid CG PUSCH;

As shown in fig. 3e, if one CG PUSCH is partially overlapped with the UL subband and UL time domain unit, the CG PUSCH is an effective CG PUSCH;

As shown in fig. 3f, the network may indicate that if a CG PUSCH resource or a part of the resources is less than a preconfigured value from the GB frequency resource, the CG PUSCH is an invalid CG PUSCH;

As shown in fig. 3g, if one CG PUSCH resource or part of the resources overlaps with GB, the CG PUSCH is an invalid CG PUSCH;

in one possible embodiment, the method further comprises:

under the condition that the terminal selects the CG PUSCH resource of the first type, if the first condition is met, the terminal is switched to the CG PUSCH resource of the second type;

Wherein the first condition comprises at least one of:

(1) All SDTs fail within a first preset time period;

optionally, the network may configure a timer for SDT detection failure per CG PUSCH type;

for CG PUSCH type A, timer K for SDT detection failure;

for CG PUSCH type B, timer L for SDT detection failure;

if the UE prefers CG PUSCH resources/type a, then the UE switches to CG PUSCH resources/type B when:

if the SDT detection failure timer K is up to time-out, namely the timer K is invalid (expire) or all SDTs fail within a configured time period;

By the above (1), by configuring the timer for detecting failure of the SDT, whether all SDTs fail within the first preset duration is determined by using whether the timer is overtime, if yes, the terminal is switched from the first type CG PUSCH resource to the second type CG PUSCH resource, so that the terminal can switch to the more suitable CG PUSCH resource, and uplink transmission is ensured by using the suitable CG PUSCH resource.

(2) And repeating the transmission times on the CG PUSCH resource of the first type to reach the first preset transmission times.

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

CG-PUSCH type a configures CG-PUSCH-RetransmissionTimer A;

CG-PUSCH type B configures CG-PUSCH-RetransmissionTimer B;

If the UE transmits a CG-PUSCH type A, at RetransmissionTimer A, the UE automatically retransmits the retransmission of CG-PUSCH type A without timeout.

Alternatively, if the UE transmits one CG-PUSCH type a, after RetransmissionTimer A times out, the UE switches to CG PUSCH resources/type B.

Through the above (2), by configuring the CG-PUSCH retransmission timer, whether the number of repeated transmissions on the first type of CG PUSCH resources reaches the first preset number of transmissions is judged by using whether the CG-PUSCH retransmission timer is overtime, if the CG-PUSCH retransmission timer is overtime, the number of repeated transmissions reaches the first preset number of transmissions, the CG-PUSCH resources are switched to the second type of CG PUSCH resources, so that the terminal can be switched to more suitable CG PUSCH resources, the terminal is prevented from occupying excessive time on one type of CG PUSCH resources, the improvement of the transmission delay of the terminal is facilitated, and the uplink transmission is ensured by using suitable CG PUSCH resources.

In one possible embodiment, the method further comprises:

Or if the second condition is met, the terminal declares that the SDT fails and enters a connection state through random access;

Wherein the second condition comprises at least one of:

(1) All SDTs fail within a second preset time period and are configured with Random Access (RA) resources for random access small data transmission (RA-SDT);

that is, if the SDT detection failure timer L times out and if the RA resource set of RA-SDT is configured, the UE performs an RACH-based SDT transmission procedure or declares SDT failure and enters a connection state through random access;

Through the step (1), whether all SDTs fail in the second preset time period is judged by configuring the timer with the failure of SDT detection or not, if the timer is overtime, the terminal executes the SDT transmission process based on the RACH, or the terminal declares the SDT failure and enters a connection state through random access, so that the terminal can carry out the SDT through the RACH under the condition that the selected CG PUSCH resource is unsuitable, or directly select to enter the connection state, the terminal is prevented from occupying excessive time on one type of CG PUSCH resource, the improvement of the transmission delay of the terminal is facilitated, and the uplink transmission can be ensured.

(2) Repeating the transmission times on all CG PUSCH resources to reach a second preset transmission times;

Namely, if both CG-PUSCH-RetransmissionTimer A and CG-PUSCH-RetransmissionTimer B are overtime, the UE executes the SDT transmission process based on the RACH, or declares the SDT failure and enters a connection state through random access;

Through the step (2), whether the repeated transmission times on all types of CG PUSCH resources reach the second preset transmission times is judged by configuring the CG-PUSCH retransmission timers and judging whether the repeated transmission times on all types of CG PUSCH resources reach the second preset transmission times or not through overtime of all CG-PUSCH retransmission timers, if the repeated transmission times on all types of CG PUSCH resources reach the second preset transmission times, the terminal executes the SDT transmission process based on the RACH, or the terminal declares the SDT failure and enters a connection state through random access, so that the terminal can carry out the SDT through the RACH under the condition that the selected CG PUSCH resources are unsuitable, or directly select the connection state, thereby being beneficial to improving the transmission delay of the terminal and ensuring that the terminal can execute uplink transmission.

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

If different CG PUSCH types map to different sets of measurement signals (such as SSBs), the TA validity determination for the different CG PUSCH types may be different. The set of measurement signals (e.g., SSBs) that the TA validity may verify for different CG PUSCH resource types may be different, at which time the resulting TA change size may be different, and thus the TA validity may also be different.

And (3) judging whether the TAs corresponding to the CG PUSCH resources of all types are valid or not, if the TAs corresponding to the CG PUSCH resources of all types are invalid, executing the SDT transmission process based on the RACH by the terminal, or declaring the SDT failure by the terminal, entering a connection state through random access, enabling the terminal to execute the SDT through the RACH under the condition that the selected CG PUSCH resources are unsuitable, or directly selecting the connection state, thereby being beneficial to improving the transmission delay of the terminal and ensuring that the uplink transmission can be executed.

The TA validity satisfies the following condition:

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

2. The currently calculated DL path loss reference RSRP value varies by no more than a predefined threshold compared to the stored DL path loss reference RSRP.

3. A predefined timer is running, for example (timer for timing alignment:

CG-SDT-TimeAlignmentTimer)

if the UE selects CG PUSCH resources/type A, the UE switches to CG PUSCH resources/type B when the following condition is satisfied;

if the terminal transmits the used TA on the CG PUSCH resource A is invalid, but the terminal transmits the used TA on the CG PUSCH resource B is valid.

Alternatively, if the corresponding TA is invalid for all CG PUSCH resource types, the UE performs RACH based SDT transmission procedure.

Alternatively, if the corresponding TA is invalid for all CG PUSCH resource types, the UE performs the announce sdt failure, attempting random access into connected state.

In some other embodiments, the network may configure CG PUSCH resources/type a to use different transmit powers than CG PUSCH resources/type B, which typically have a transmit power greater than that of CG PUSCH resources/type a.

In some other embodiments, the network may configure CG PUSCH resource type a and CG PUSCH resource type B to associate different reference signal resources (such as SSBs).

The terminal associates a plurality of reference signal resources (such as SSB) in CG PUSCH resource type A, the network can predefine or configure a threshold value, if the measured value (such as SS-RSRP) of any one or a plurality of measurement metrics is smaller than the threshold value, the UE is switched to CG PUSCH resource/type B by CG PUSCH resource/type A;

That is, if the terminal's measured value (e.g., SS-RSRP) of a certain measurement metric on a CG PUSCH resource a associated reference signal resource (e.g., SSB) is less than or not greater than a certain predefined or network configured threshold.

Further, the network may configure the UE to perform a RACH based SDT transmission procedure if the measured value of a certain measurement metric (such as SS-RSRP) on all CG PUSCH resources associated reference signal resources (such as SSB) is less than or not greater than a certain predefined or network configured threshold.

Alternatively, if the measured value (such as SS-RSRP) of a certain measurement metric on all CG PUSCH resources associated reference signal resources (such as SSB) is less than or not greater than a certain predefined or network configured threshold, the UE performs the announce sdt failure, attempting random access to enter the connected state.

In some other embodiments, the configuration of the network per CG-PUSCH resource type may include at least one of the following configuration information:

(1) A time domain offset (timeDomainOffset);

(2) Time domain allocation (timeDomainAllocation);
