For ease of understanding, the terms related to the present embodiment will first be described.

1. Time advance (TIMING ADVANCE, TA)

In order for the uplink signal transmitted by the terminal device to arrive at the network device at a predetermined time, it is necessary for the terminal device to transmit the uplink signal in advance, where the time for the terminal device to transmit the uplink signal in advance is determined according to the TA.

2. Physical Uplink shared channel (Physical Uplink SHARED CHANNEL, PUSCH)

The PUSCH is used as a main uplink data carrying channel of the physical layer, and is used for uplink data transmission, and can carry control information, user service information, broadcast service information and the like.

3. Physical downlink shared channel (Physical Downlink SHARED CHANNEL, PDSCH)

The PDSCH is used to carry data from the transport Downlink shared channel (Downlink SHARED CHANNEL, DL-SCH).

4. ERedCap terminal

The third generation partnership project (3rd Generation Partnership Project,3GPP) establishes a special standard project in the phase of the communication protocol version 17 (release 17, rel-17) to analyze and optimize the functional characteristics of the existing 5G terminals and networks to realize that the 5G internet of things terminals access the 5G core network through a New air interface (NR). In this standard project,3GPP proposes an NR device with reduced support capability (Reduced Capability), i.e., redCap terminal. Compared with traditional enhanced mobile broadband (enhanced mobile broadband, eMBB) equipment and ultra-reliable low-latency communication (ultra-reliable and low latencycommunication, URLLC) equipment, the RedCap terminal equipment has the advantages of lower cost, lower complexity, more compact size, adequate performance and the like. And eRedCap terminals are based on RedCap terminals, so that the terminal cost is further reduced, and the 5G Internet of things terminal with low rate is supported to use the NR technology.

Currently, in the study item of communication protocol release 18 (R18), it is proposed to relax the processing delay of the terminal, such as relaxing the processing delay with respect to the processing time (processingtime) of the PDSCH channel and the preparation time (preparation time) of the PUSCH channel, so as to reduce the cost of the terminal. If the processing delay of eRedCap terminals is relaxed based on the processing capability of the legacy terminals, for example, to twice the original, the TA adjustment effective time set for the legacy terminals will not be suitable for eRedCap terminals. The effective time of the TA adjustment needs to be re-determined to ensure eRedCap that the terminal can perform uplink time adjustment and PUSCH channel preparation in a reasonable manner. But there is currently no effective solution for redetermining the effective time of TA adjustment for eRedCap terminals.

Therefore, the present embodiment provides a method and apparatus for determining the effective time of TA adjustment, which provides an effective solution for determining the effective time of TA adjustment for eRedCap terminals, so as to ensure that eRedCap terminals can prepare PUSCH channel data according to a new timing relationship before starting a new TA.

The method and apparatus for determining the effective time of TA adjustment provided by the present application are described in detail below with reference to the accompanying drawings.

Fig. 1 is a flowchart of a method for determining a validation time of TA adjustment according to an embodiment of the present application. As shown in fig. 1, the method can be applied to the eRedCap terminal side or the base station side for execution, and can comprise the following steps.

And 101, acquiring eRedCap channel processing capability parameters of the terminal.

Wherein the channel processing capability parameter of eRedCap terminal includes at least one of the following:

A first processing capability of the PDSCH channel; and a second processing capability of the PUSCH channel.

Both the first processing capability and the second processing capability may be considered as the processing capability of the PDSCH channel and the processing capability of the PUSCH channel newly introduced for the eRedCap terminal, as compared to the RedCap terminal and the legacy terminal. The first processing capability of the PDSCH channel of the eRedCap terminal is lower than that of the PDSCH channel of the RedCap terminal, the processing delay of the eRedCap terminal with respect to the PDSCH channel is relaxed, and the processing capability of the PDSCH channel of the RedCap terminal may be the same as that of the PDSCH channel of the legacy terminal. In an embodiment of the present disclosure, the processing capability of the PDSCH channel of RedCap terminals or legacy terminals is referred to as a third processing capability.

The second processing capability of the PUSCH channel of the eRedCap terminal is lower than that of the PUSCH channel of the RedCap terminal, the processing delay of the eRedCap terminal with respect to the PUSCH channel can be relaxed, and the processing capability of the PUSCH channel of the RedCap terminal can be the same as that of the PUSCH channel of the traditional terminal. In the embodiment of the present disclosure, the processing capability of the PUSCH channel of the RedCap terminal or the legacy terminal is referred to as a fourth processing capability.

Step 102, determining eRedCap the effective time of the TA adjustment of the terminal based on the channel processing capability parameter of the eRedCap terminal.

The TA adjusted validation time may be used to determine when the currently adjusted TA is validated, ensuring eRedCap that the terminal can prepare PUSCH channel data in a new timing relationship before enabling a new TA.

By applying the TA adjustment validation time determining method provided in this embodiment, the TA adjustment validation time of the eRedCap terminal may be determined based on the first processing capability of the PDSCH channel and/or the second processing capability of the PUSCH channel of the eRedCap terminal, where the first processing capability of the PDSCH channel is lower than the processing capability and the second processing capability of the PUSCH channel is lower than the processing capability. The embodiment can redetermine the effective time of the TA adjustment for the eRedCap terminal, so as to ensure that the eRedCap terminal can prepare PUSCH channel data according to a new timing relationship before starting a new TA, thereby ensuring correct transmission of uplink data.

Fig. 2 is a flow chart of a method for determining the effective time of TA adjustment according to an embodiment of the present application. Based on the embodiment shown in fig. 1, as shown in fig. 2, can be applied to eRedCap terminal sides, and the method can include the following steps.

Step 201, obtaining eRedCap channel processing capability parameters of the terminal.

The first processing capability is lower than the processing capability of the PDSCH channel of the RedCap terminal, while the processing capability of the PDSCH channel of the RedCap terminal may be the same as the processing capability of the PDSCH channel of the legacy terminal; the second processing capability is lower than the processing capability of the PUSCH channel of the RedCap terminal, and the processing capability of the PUSCH channel of the RedCap terminal may be the same as the processing capability of the PUSCH channel of the legacy terminal.

Step 202, if eRedCap terminal supports the first processing capability of PDSCH channel and the second processing capability of PUSCH channel, determining the effective time of TA adjustment of eRedCap terminal based on the first processing capability of PDSCH channel and the second processing capability of PUSCH channel.

In a specific application, an alternative way is to make eRedCap terminals support only the first processing capability of the PDSCH channel and the second processing capability of the PUSCH channel (compared to RedCap terminals and legacy terminals, the processing capability of the PDSCH channel and the processing capability of the PUSCH channel newly introduced for eRedCap terminals). For example, eRedCap terminal supports processing capability (UE processing capability 1') of newly introduced PDSCH channel and PUSCH channel, i.e. first processing capability and second processing capability supported by the eRedCap terminal; in this case, the effective time of the TA adjustment of the eRedCap terminal may be determined based on the processing capabilities (UE processing capability 1') of the newly introduced PDSCH channel and PUSCH channel, i.e., the first and second processing capabilities supported by the eRedCap terminal.

Another alternative is to make the first processing capability of the PDSCH channel and the second processing capability of the PUSCH channel be the capabilities that eRedCap terminals must support. For example, eRedCap terminals may actually support processing capability 1 (UE processing capability) of PDSCH channels and PUSCH channels, where the processing capability 1 is the same as the processing capability 1 of RedCap terminals or legacy terminals, and the processing capability 1 may be a mandatory capability for RedCap terminals or legacy terminals, and must be supported. Further, eRedCap terminals may actually support processing capability 2 (UEprocessingcapability) of PDSCH channel and PUSCH channel, where processing capability 2 is the same as that of RedCap terminal or legacy terminal, and channel processing capability 2 may be an optional capability for RedCap terminal or legacy terminal. For eRedCap terminals, if the processing capability (UE processing capability ') of the PDSCH channel and the PUSCH channel is the capability that the eRedCap terminal must support, the effective time of the TA adjustment of the eRedCap terminal is determined based on the processing capability (UE processing capability 1') of the PDSCH channel and the PUSCH channel, i.e., the first processing capability and the second processing capability supported by the eRedCap terminal, regardless of whether the eRedCap terminal supports the processing capability 1 (UE processing capability 1) and the processing capability 2 (UEprocessingcapability 2).

Yet another alternative is based on the processing power situation supported by eRedCap terminals. For example, in practical applications, the processing capabilities (UE processing capability 1') of the PDSCH channel and the PUSCH channel (i.e., the first processing capability and the second processing capability supported by the eRedCap terminal) are not all the capabilities that the eRedCap terminal can support. For processing capabilities (UE processing capability 1 ') (i.e., the first processing capability and the second processing capability supported by the eRedCap terminal), the eRedCap terminal may or may not be supported, so that if the eRedCap terminal supports the processing capabilities (UE processing capability 1 ') of the PDSCH channel and the PUSCH channel, the effective time of TA adjustment of the eRedCap terminal is determined based on the processing capabilities (UE processing capability 1 ') of the PDSCH channel and the PUSCH channel, i.e., the first processing capability and the second processing capability supported by the eRedCap terminal, according to the processing capability situation supported by the eRedCap terminal; if eRedCap terminals do not support the processing capabilities of the PDSCH channel and PUSCH channel (UE processing capability 1'), the validation time of the TA adjustment for the eRedCap terminal may be determined based on the lowest processing capabilities supported by the eRedCap terminal.

To illustrate how the effective time of the TA adjustment for the eRedCap terminal is determined based on the first processing capability of the PDSCH channel and the second processing capability of the PUSCH channel, the process may include: and determining the effective time of TA adjustment of the eRedCap terminal according to the processing time (PDSCHprocessingtime) of the PDSCH channel corresponding to the first processing capability supported by the eRedCap terminal and the preparation time (PUSCH preparation time) of the PUSCH channel corresponding to the second processing capability supported by the eRedCap terminal.

For example, let the time when the TA adjustment command is received be slot _n, and after a time interval of K slots, a new TA is validated on slot _n+K+1. The calculation mode of K is shown in formula one:

in the first formula of the present invention, Representing the number of slots in one subframe when the subcarrier spacing is mu; n _T,1 represents the processing time (PDSCHprocessingtime) of the PDSCH channel corresponding to the first processing capability supported by the eRedCap terminal; n _T,2 represents a preparation time (PUSCH preparation time) of the PUSCH channel corresponding to the second processing capability supported by the eRedCap terminal; n _TA,max represents the maximum value of TA; t _sf represents the physical time length of one subframe.

In the above exemplary manner, the effective time of TA adjustment of the eRedCap terminal may be accurately determined according to the processing time of the PDSCH channel corresponding to the first processing capability supported by the eRedCap terminal and the preparation time of the PUSCH channel corresponding to the second processing capability supported by the eRedCap terminal.

Further optionally, after step 202, the present embodiment may further include: and executing eRedCap the preparation of the uplink data of the terminal based on the determined effective time of the TA adjustment.

For example, if the uplink data transmission time of eRedCap terminals is on any slot (slot) from slot _n to slot _n+K, the preparation of uplink data is performed according to the time-frequency resource grid determined by the TA (legacy TA) in the related art; if the uplink data transmission time of eRedCap terminal is on a slot (such as slot _n+K+1 and the following) after slot _n+K, the uplink data is prepared according to the time-frequency resource grid determined by the new TA, where slot _n represents the time when the TA adjustment command is received by the eRedCap terminal, and slot _n+K represents the time interval from when the TA adjustment command is received to when the new TA is valid. The TA (legacy TA) in the related art is a TA configured corresponding to the legacy UE (legacy), or a TA configured corresponding to the RedCap terminal.

By applying the TA adjustment validation time determining method provided in this embodiment, in the case that the eRedCap terminal only supports the first processing capability of the PDSCH channel and the second processing capability of the PUSCH channel, or the first processing capability of the PDSCH channel and the second processing capability of the PUSCH channel must be supported (the terminal may also support other processing capabilities), or the eRedCap terminal may support the first processing capability of the PDSCH channel and the second processing capability of the PUSCH channel, the TA adjustment validation time of the eRedCap terminal is determined based on the processing capabilities of the PDSCH channel and the PUSCH channel, that is, the first processing capability and the second processing capability supported by the eRedCap terminal. Under the demand scene of relaxing the processing time delay of the terminal, the effective time of TA adjustment can be determined again for the eRedCap terminal, so that the eRedCap terminal can be ensured to be ready for PUSCH (physical uplink shared channel) data according to a new time sequence relation before starting a new TA, and the correct sending of uplink data is ensured.

Fig. 3 is a flowchart of a method for determining a validation time of TA adjustment according to an embodiment of the present application. Based on the embodiment shown in fig. 1 or fig. 2, as shown in fig. 3, the method can be applied to eRedCap terminal side execution, and the method can include the following steps.

Step 301, obtaining eRedCap channel processing capability parameters of the terminal.

Wherein the first processing capability is lower than the processing capability of the PDSCH channel of the RedCap terminal, and the processing capability of the PDSCH channel of the RedCap terminal may be the same as the processing capability of the PDSCH channel of the legacy terminal; the second processing capability is lower than the processing capability of the PUSCH channel of the RedCap terminal, and the processing capability of the PUSCH channel of the RedCap terminal may be the same as the processing capability of the PUSCH channel of the legacy terminal.

In step 302, if eRedCap terminal supports the first processing capability of PDSCH channel and eRedCap terminal does not support the second processing capability of PUSCH channel, the effective time of TA adjustment of eRedCap terminal is determined based on the first processing capability and the third processing capability of eRedCap terminal with respect to PUSCH channel support.

The third processing capability may be the same as that of RedCap terminals or legacy terminals with respect to PUSCH channel support.

For example, if eRedCap terminal supports a first processing capability of PDSCH channel but eRedCap terminal does not support a second processing capability of PUSCH channel, then the validation time of TA adjustment for eRedCap terminal is determined based on the first processing capability of PDSCH channel and the third processing capability of eRedCap terminal with respect to PUSCH channel support (same as eRedCap terminal or legacy terminal with respect to PUSCH channel support).

Illustratively, determining eRedCap the effective time of the TA adjustment of the terminal based on the first processing capability and the third processing capability of the eRedCap terminal with respect to PUSCH channel support may specifically include: and determining the effective time of TA adjustment of the eRedCap terminal according to the processing time of the PDSCH channel corresponding to the first processing capability supported by the eRedCap terminal and the preparation time of the PUSCH channel corresponding to the third processing capability supported by the eRedCap terminal.

For example, let the time when the TA adjustment command is received be slot _n, and after a time interval of K slots, a new TA is validated on slot _n+K+1. The calculation mode of K is shown in formula one, where N _T,1 in formula one also represents the processing time (PDSCHprocessingtime) of the PDSCH channel corresponding to the first processing capability supported by the eRedCap terminal; and N _T,2 represents the preparation time (PUSCH preparation time) of the PUSCH channel corresponding to the third processing capability supported by the eRedCap terminal.

In the above exemplary manner, the effective time of TA adjustment of the eRedCap terminal may be accurately determined according to the processing time of the PDSCH channel corresponding to the first processing capability supported by the eRedCap terminal and the preparation time of the PUSCH channel corresponding to the third processing capability supported by the eRedCap terminal.

Further optionally, after step 302, the present embodiment may further include: and executing eRedCap the preparation of the uplink data of the terminal based on the determined effective time of the TA adjustment. For a specific implementation procedure, reference may be made to the description in step 202, which is not repeated here.

By applying the TA adjustment effective time determining method provided in this embodiment, in the case that the eRedCap terminal supports the first processing capability of the PDSCH channel and the eRedCap terminal does not support the second processing capability of the PUSCH channel, the TA adjustment effective time of the eRedCap terminal may be determined based on the first processing capability of the PDSCH channel and the third processing capability of the eRedCap terminal supported by the PUSCH channel, so that the TA adjustment effective time may be determined again for the eRedCap terminal, and further it may be ensured that the eRedCap terminal may prepare PUSCH channel data according to the new timing relationship before starting the new TA, thereby ensuring correct transmission of uplink data.

Fig. 4 is a flowchart of a method for determining a validation time of TA adjustment according to an embodiment of the present application. Based on the embodiment shown in fig. 1, as shown in fig. 4, the method can be applied to eRedCap terminal side execution, and can include the following steps.

Step 401, obtaining eRedCap channel processing capability parameters of the terminal.

In step 402, if eRedCap terminal supports the second processing capability of PUSCH channel and eRedCap terminal does not support the first processing capability of PDSCH channel, the effective time of TA adjustment of eRedCap terminal is determined based on the fourth processing capability of eRedCap terminal supported by PDSCH channel and the second processing capability of PUSCH.

The fourth processing capability may be the same as that of RedCap terminals or legacy terminals with respect to PUSCH channel support.

For example, if eRedCap terminal supports the second processing capability of the PUSCH channel, but eRedCap terminal does not support the first processing capability of the PDSCH channel, then the validation time of the TA adjustment for the eRedCap terminal is determined based on the fourth processing capability of the eRedCap terminal with respect to the PDSCH channel support and the second processing capability of the PUSCH channel.

Illustratively, determining eRedCap the effective time of the TA adjustment for the terminal based on the fourth processing capability and the second processing capability supported by the eRedCap terminal with respect to the PDSCH channel may specifically include: and determining the effective time of TA adjustment of the eRedCap terminal according to the processing time of the PDSCH channel corresponding to the fourth processing capability supported by the eRedCap terminal and the preparation time of the PUSCH channel corresponding to the second processing capability supported by the eRedCap terminal.

For example, let the time when the TA adjustment command is received be slot _n, and after a time interval of K slots, a new TA is validated on slot _n+K+1. The calculation mode of K is shown in formula one, where N _T,1 in formula one represents the processing time (PDSCHprocessingtime) of the PDSCH channel corresponding to the fourth processing capability supported by the eRedCap terminal; and N _T,2 also represents the preparation time (PUSCH preparation time) of the PUSCH channel corresponding to the second processing capability supported by the eRedCap terminal.

In the above exemplary manner, the effective time of TA adjustment of the eRedCap terminal may be accurately determined according to the processing time of the PDSCH channel corresponding to the fourth processing capability supported by the eRedCap terminal and the preparation time of the PUSCH channel corresponding to the second processing capability supported by the eRedCap terminal.

Further optionally, after step 402, the present embodiment may further include: and executing eRedCap the preparation of the uplink data of the terminal based on the determined effective time of the TA adjustment. For a specific implementation procedure, reference may be made to the description in step 202, which is not repeated here.

By applying the TA adjustment effective time determining method provided in this embodiment, in the case that eRedCap terminals support the second processing capability of the PUSCH channel and eRedCap terminals do not support the first processing capability of the PDSCH channel, the TA adjustment effective time of the eRedCap terminal may be determined based on the fourth processing capability of the eRedCap terminal supported by the PDSCH channel and the second processing capability of the PUSCH, so that the TA adjustment effective time may be determined again for the eRedCap terminal, so as to ensure that the eRedCap terminal can prepare PUSCH channel data according to the new timing relationship before starting the new TA, thereby ensuring correct transmission of uplink data.

Fig. 5 is a flowchart of a method for determining a validation time of TA adjustment according to an embodiment of the present application. Based on the embodiment shown in fig. 1, as shown in fig. 5, the method may be applied to the base station side for execution, and may include the following steps.

In a specific application, if the first processing capability of the PDSCH channel and the second processing capability of the PUSCH channel are not the capabilities that eRedCap terminals support only, or are not the capabilities that eRedCap terminals must support (the terminals may also support other processing capabilities), in this case, the processing capabilities of the PDSCH channel and the PUSCH channel (the first processing capability and the second processing capability) are not the capabilities that all eRedCap terminals can support. For the first processing capability and the second processing capability, the eRedCap terminal may or may not support, so on the base station side, it is required to determine whether the eRedCap terminal supports the first processing capability of the PDSCH channel and/or the second processing capability of the PUSCH channel based on the processing capability information reported by the eRedCap terminal (e.g., reporting that the first processing capability and/or the second processing capability are not supported through UEcapability signaling, or reporting that the first processing capability and/or the second processing capability are supported and further supporting other processing capabilities are not reported, etc.).

In step 503a, if eRedCap terminal supports the first processing capability of PDSCH channel and the second processing capability of PUSCH channel, the effective time of TA adjustment of eRedCap terminal is determined based on the first processing capability of PDSCH channel and the second processing capability of PUSCH channel.

Illustratively, determining eRedCap the effective time of the TA adjustment of the terminal based on the first processing capability and the second processing capability may specifically include: the effective time of the TA adjustment for the terminal eRedCap is determined based on the processing time of the terminal eRedCap on the PDSCH channel with the first processing capability (PDSCHprocessingtime) and the preparation time of the terminal eRedCap on the PUSCH channel with the second processing capability (PUSCH preparation time). In this exemplary manner, the effective time of the TA adjustment of eRedCap terminals can be accurately determined.

The specific implementation process may be explained in step 202, and will not be described herein.

In step 503b in parallel with step 503a, if eRedCap terminal supports the first processing capability of PDSCH channel and eRedCap terminal does not support the second processing capability of PUSCH channel, the validation time of TA adjustment for eRedCap terminal is determined based on the first processing capability of PDSCH channel and the third processing capability of eRedCap terminal with respect to PUSCH channel support.

Illustratively, determining eRedCap the effective time of the TA adjustment of the terminal based on the first processing capability and the third processing capability of the eRedCap terminal with respect to PUSCH channel support may specifically include: and determining the effective time of TA adjustment of the eRedCap terminal according to the processing time of the PDSCH channel corresponding to the first processing capability supported by the eRedCap terminal and the preparation time of the PUSCH channel corresponding to the third processing capability supported by the eRedCap terminal. In this exemplary manner, the effective time of the TA adjustment of eRedCap terminals can be accurately determined.

The specific implementation process may be explained in step 302, and will not be described herein.

In step 503c, in parallel with steps 503a and 503b, if eRedCap terminal supports the second processing capability of PUSCH channel and eRedCap terminal does not support the first processing capability of PDSCH channel, the validation time of TA adjustment of eRedCap terminal is determined based on the fourth processing capability of eRedCap terminal supported with respect to PDSCH channel and the second processing capability of PUSCH channel.

Illustratively, determining eRedCap the effective time of the TA adjustment for the terminal based on the fourth processing capability and the second processing capability supported by the eRedCap terminal with respect to the PDSCH channel may specifically include: and determining the effective time of TA adjustment of the eRedCap terminal according to the processing time of the PDSCH channel corresponding to the fourth processing capability supported by the eRedCap terminal and the preparation time of the PUSCH channel corresponding to the second processing capability supported by the eRedCap terminal. In this exemplary manner, the effective time of the TA adjustment of eRedCap terminals can be accurately determined.

The specific implementation process may be referred to the explanation in step 402, and will not be described herein.

And 504, based on the determined effective time of the TA adjustment, scheduling eRedCap uplink data of the terminal is executed.

For example, after performing step 503a, step 503b, or step 503c to obtain the effective time of the TA adjustment, the reasonable scheduling of the uplink data of the eRedCap terminal may be performed based on the determined effective time of the TA adjustment.

By applying the method for determining the effective time of the TA adjustment provided by the embodiment, the effective time of the TA adjustment can be determined again for the eRedCap terminal, so that the eRedCap terminal can be ensured to be ready for PUSCH channel data according to a new timing relationship before starting a new TA, and correct transmission of uplink data is ensured.
