Description

Channel scheduling method, device and communication equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a channel scheduling method, an apparatus, and a communication device.

Background

Compared with the conventional mobile communication system, the 5G mobile communication system needs to be adapted to more diversified scenes and service requirements. The main scenes of 5G include enhanced Mobile Broadband (eMBB), Low-Latency and high-reliability connections (URLLC), large-scale (massive) Machine Type Communication (mtc), which provide requirements for the system such as high reliability, Low Latency, large bandwidth, wide coverage, and the like.

In New Radio (NR), for Physical Uplink Control Channel (PUCCH) scheduling, a base station may schedule a low priority Physical Uplink Shared Channel (PUSCH) (e.g., eMBB service), and then a terminal (User Equipment, UE) has higher priority traffic data to be scheduled (e.g., low-latency URLLC), so that the base station schedules another PUSCH. Since the UE can only transmit one PUSCH at a time, the UE needs to drop the low priority PUSCH. However, it takes a certain time for the UE to decode the PDCCH and discard the PUCCH/PUSCH, so the scheduling of the high priority PUCCH/PUSCH cannot be too late, otherwise the UE has no time to cancel.

The techniques described herein may be used for both the above-mentioned systems and radio technologies, as well as for other systems and radio technologies. However, the following description describes the NR system for purposes of example, and NR terminology is used in much of the description below, although the techniques may also be applied to applications other than NR system applications.

The following description provides examples and does not limit the scope, applicability, or configuration set forth in the claims. Changes may be made in the function and arrangement of elements discussed without departing from the spirit and scope of the disclosure. Various examples may omit, substitute, or add various procedures or components as appropriate. For example, the described methods may be performed in an order different than described, and various steps may be added, omitted, or combined. In addition, features described with reference to certain examples may be combined in other examples.

In NR, only in-order (in order) scheduling and Hybrid automatic repeat request (HARQ) are supported, i.e. early scheduling of early transmission and early scheduling of early feedback, as shown in fig. 1, a feedback slot of a Hybrid automatic repeat request acknowledgement (HARQ-ACK) of a first scheduled Physical Downlink Shared Channel (PDSCH) cannot follow a feedback slot of a HARQ-ACK of a second scheduled PDSCH.

For a UE supporting both eMBB and URLLC services, after a PDSCH transmission is scheduled by an NR Node (NR Node B, gNB), there may be an arrival of URLLC service, and due to the requirement of low latency of URLLC service, HARQ-ACK of PDSCH may be fed back before HARQ-ACK of eMBB, so HARQ-ACK of PDSCH scheduled later is fed back preferentially instead, which is called out-of-order (out-of-order) HARQ as shown in fig. 2.

Support for out-of order HARQ is beneficial for guaranteeing transmission of URLLC traffic, but has higher requirements on UE capabilities, for some UEs may need to decode 2 PDSCHs simultaneously, for some low-rank UEs the PDSCH transmission of eMBB may not be able to decode and needs to be dropped, which of course reduces the performance of eMBB traffic.

In the current NR, the processing capabilities of the PDSCH/Physical Uplink Shared Channel (PUSCH) that can be reported by the UE include 2 types, i.e., PDSCH/PUSCH processing capability 1 and PDSCH/PUSCH processing capability 2, and compared to PDSCH/PUSCH processing capability 1, PDSCH/PUSCH processing capability 2 has a shorter time for decoding/encoding PDSCH/PUSCH, and can feed back HARQ-ACK and transmit PUSCH faster.

When the UE supports different service types, in order to meet different service type requirements, the UE may simultaneously support different processing capabilities, i.e., PDSCH processing capability 1 and PDSCH processing capability 2, where the eMBB schedules and feeds back according to PDSCH processing capability 1, and the URLLC schedules and feeds back according to PDSCH processing capability 2. When the UE supports different traffic types, the UE may construct two HARQ-ACK codebooks at the same time and then transmit the two HARQ-ACK codebooks on different PUCCH resources, but HARQ-ACK PUCCH feedback resources of the two different traffic types may overlap in time, and due to the limitation of Peak to Average power ratio (PARP))/Cubic Metric (CM), the UE can only transmit one PUCCH at the same time, so the UE can either multiplex HARQ-ACKs of different traffic on one channel or discard one and transmit the other.

For PUSCH scheduling, the base station may schedule a low priority PUSCH (e.g., eMBB service) first, and then the UE has higher priority traffic data to be scheduled (e.g., low latency URLLC), so the base station schedules another PUSCH, but due to limited resources, the two PUSCHs are in one serving cell and overlap in time. Since the UE can only transmit one PUSCH at a time, the UE needs to drop the low priority PUSCH. However, it takes a certain time for the UE to decode the PDCCH and discard the PUCCH/PUSCH, so the scheduling of the high priority PUCCH/PUSCH cannot be too late, otherwise the UE has no time to cancel. For the hybrid capability, the timeline requirements for UE multiplexing or dropping PUCCH/PUSCH need to be defined.

In order to solve the above problem, embodiments of the present invention provide a channel scheduling method, an apparatus, and a communication device, which may reduce a limitation on scheduling of a high-priority service.

An embodiment of the present invention provides a channel scheduling method, which is applied to a network side device, and as shown in fig. 3, the method includes:

step 101: sending first scheduling information of a first uplink channel to a terminal;

step 102: sending second scheduling information of a second uplink channel to the terminal, wherein the priority of the second uplink channel is higher than that of the first uplink channel;

In this embodiment, the network side device sends, to the terminal, first scheduling information of a first uplink channel and second scheduling information of a second uplink channel, where a priority of the second uplink channel is higher than a priority of the first uplink channel, where the first uplink channel and the second uplink channel are overlapped in time, and an interval between an end position of the second scheduling information and a start position of the second uplink channel and/or the first uplink channel is greater than or equal to a preset time length, so that processing time of the high-priority scheduling information can be ensured, and a limitation on scheduling of a high-priority service is reduced.

Wherein the first uplink channel and the second uplink channel overlapping in time includes the first uplink channel and the second uplink channel partially overlapping in time, and the first uplink channel and the second uplink channel completely overlapping in time.

The priority of the first uplink channel and the priority of the second uplink channel can be determined through physical layer indication or a predefined mode, and the priority of the second uplink channel higher than the priority of the first uplink channel can also indicate that the priority of the second uplink channel for bearing the content is higher than the priority of the first uplink channel for bearing the content.

In a specific embodiment, the first uplink channel includes a first physical uplink control channel, and the second uplink channel includes a second physical uplink control channel, where the method specifically includes:

sending the first scheduling information to the terminal through a first physical downlink control channel, wherein the first scheduling information schedules a first physical downlink shared channel or indicates to release a first semi-persistent scheduling (SPS) physical downlink shared channel, and the first scheduling information further indicates the terminal to feed back hybrid automatic repeat request acknowledgement (HARQ-ACK) on the first physical uplink control channel, and the terminal can feed back the first physical downlink shared channel or the first scheduling information, namely the HARQ-ACK indicating to release a Physical Downlink Control Channel (PDCCH) of a first SPS physical downlink shared channel, on the first physical uplink control channel;

sending the second scheduling information to the terminal through a second physical downlink control channel, wherein the second scheduling information schedules the second physical downlink shared channel or indicates to release the second SPS physical downlink shared channel, and the second scheduling information further indicates the terminal to feed back HARQ-ACK on the second physical uplink control channel, and the terminal can feed back the second physical downlink shared channel or the second scheduling information, that is, HARQ-ACK indicating to release a PDCCH of the second SPSPDSCH, on the second physical uplink control channel;

the second physical uplink control channel and the first physical uplink control channel are overlapped in time, and the interval between the ending position of the second physical downlink control channel and the starting position of the second physical uplink control channel and/or the first physical uplink control channel is larger than or equal to a preset time length.

The terminal may feed back not only HARQ-ACKs of the first physical downlink shared channel on the first physical uplink control channel, but also needs to feed back HARQ-ACKs scheduled by these physical downlink shared channels on the first physical uplink control channel if there are other physical downlink shared channel schedules before the first physical downlink shared channel and the HARQ-ACKs scheduled by these physical downlink shared channels are fed back in the same HARQ-ACK codebook of one time unit as the first physical downlink shared channel. Similarly, the terminal may not only feed back HARQ-ACKs of the second physical downlink shared channel on the second physical uplink control channel, but if there are other physical downlink shared channel schedules before the second physical downlink shared channel and the HARQ-ACKs scheduled by these physical downlink shared channels are fed back in the same HARQ-ACK codebook of a time unit as the second physical downlink shared channel, the terminal also needs to feed back HARQ-ACKs scheduled by these physical downlink shared channels on the second physical uplink control channel.

In order to ensure that the scheduling information with high priority can be scheduled in time and ensure that the terminal has enough time to cancel the transmission of the first physical uplink control channel, the first physical downlink shared channel corresponds to the processing capability 1 of the physical downlink shared channel, the second physical downlink shared channel corresponds to the processing capability 2 of the physical downlink shared channel, and the preset time length is determined by the processing time of the physical downlink shared channel corresponding to the processing capability 2 of the physical downlink shared channel.

The first physical downlink shared channel and the second physical downlink shared channel may be in the same serving cell or in different serving cells.

Specifically, as shown in fig. 4, the UE receives PDCCH1, schedules PDSCH1, and instructs the UE to feed back its HARQ-ACK on PUCCH 1; after PDCCH1, the UE receives PDCCH2, schedules PDSCH2, and instructs the UE to feed back its HARQ-ACK on PUCCH2, with PUCCH1 and PUCCH2 resources overlapping in time.

The PDSCH1 and PDSCH2 correspond to different PDSCH processing capabilities, PDSCH1 uses PDSCH processing capability 1, and PDSCH1 uses PDSCH processing capability 2.

An interval from the PDCCH2 end position to the PUCCH1 start position is T1, and an interval from the PDCCH2 end position to the PUCCH1 start position is greater than T1, where T1 is greater than or equal to the preset time length or an interval from the PDCCH2 end position to the PUCCH2 start position is greater than or equal to the preset time length.

The size of the preset time length is related to the UE capability, and may be defined according to the PDSCH processing capability 2, and specifically may be equal to the physical downlink shared channel processing time N1 when the PDSCH processing capability 2 is used, where the value of N1 is specified by the protocol.

If an interval T1 from the PDCCH2 end position to the starting symbol position of the PUCCH1 is greater than or equal to a preset time length, the UE does not transmit PUCCH 1; if an interval T1 from the PDCCH2 ending position to the starting symbol position of the PUCCH1 is smaller than the preset time length, but an interval from the PDCCH2 ending position to the starting symbol position of the PUCCH2 is greater than the preset time length, the UE cancels transmission of the PUCCH1 after the preset time length from the PDCCH2 ending position, and the UE may transmit the PUCCH1 or not transmit the PUCCH1 after the PUCCH1 within the preset time length from the PDCCH2 ending position, which is not particularly limited.

In another specific embodiment, the first uplink channel includes a first physical uplink shared channel, the second uplink channel includes a second physical uplink shared channel, and the first physical uplink shared channel and the second physical uplink shared channel belong to the same serving cell, where the method specifically includes:

sending the first scheduling information to the terminal through a first uplink authorization message, wherein the first scheduling information indicates the terminal to transmit the first physical uplink shared channel;

sending the second scheduling information to the terminal through a second uplink authorization message, wherein the second scheduling information indicates the terminal to transmit the second physical uplink shared channel;

the second physical uplink shared channel and the first physical uplink shared channel are overlapped in time, and the interval between the ending position of the second uplink authorization message and the starting position of the second physical uplink shared channel and/or the first physical uplink shared channel is greater than or equal to a preset time length.

In order to ensure that the scheduling information with high priority can be scheduled in time and ensure that the terminal has enough time to cancel the transmission of the first physical uplink shared channel, the terminal supports a physical uplink shared channel processing capability 1 and a physical uplink shared channel processing capability 2 on the serving cell, and the preset time length is determined by the physical uplink shared channel preparation time corresponding to the physical uplink shared channel processing capability 2.

Specifically, as shown in fig. 5, if the UE configures different PUSCH processing capabilities (PUSCH processing capability 1 and PUSCH processing capability 2) in one serving cell:

the UE receives the UL grant 1 and schedules a PUSCH1 in the serving cell; after UL grant 1, the UE receives UL grant 2, PUSCH2 is scheduled in the serving cell, and PUSCH1 and PUSCH2 overlap in time. Through some methods (e.g., the received UL grant is given a higher priority after the protocol specification, or obtained through the physical layer indication information), the UE determines that the priority of PUSCH2 is higher than that of PUSCH 1. The interval from the end position of UL grant 2 to the start symbol of PUSCH1 is T2, the interval from the end position of UL grant 2 to the start symbol of PUSCH2 is greater than T2, and T2 is greater than or equal to the preset time length or the interval from the end position of UL grant 2 to the start symbol of PUSCH2 is greater than the preset time length.

The size of the preset time length is related to the UE capability and can be defined according to the PUSCH processing capability 2, specifically, T2 is equal to the PUSCH preparation time T when the PUSCH processing capability 2 is adopted_proc,2。

T_proc,2＝max((N₂+d_2,1)(2048+144)·κ2^-μ·T_C,d_2,2)

Wherein N is₂Mu is selected from (mu) depending on the terminal processing power 2 and mu_DL,μ_UL) And can obtain the maximum T_proc,2Wherein, mu_DLDepending on the downlink channel subcarrier spacing carrying the PDCCH, the PDCCH carries Downlink Control Information (DCI) scheduling the PUSCH; mu.s_ULA subcarrier spacing that depends on an uplink channel transmitting the PUSCH; d if the first symbol of the PUSCH allocation consists of DMRS only_2,1Not more than 0, otherwise d _2,11 is ═ 1; κ has been defined in the protocol; if scheduling DCI triggers a handover of bandwidth part (BWP), d_2,2Equal to the switching time defined in the protocol, otherwise d_2,2＝0。

If the interval T2 from the UL grant 2 ending position to the starting symbol position of the PUSCH1 is greater than or equal to a preset time length, the UE does not transmit the PUSCH 1; if the interval T2 from the UL grant 2 ending position to the PUSCH1 starting symbol position is less than the preset time length, but the interval from the UL grant 2 ending position to the PUSCH2 starting symbol position is greater than or equal to the preset time length, the UE cancels transmission of the PUSCH1 after the preset time length from the UL grant 2 ending position, and the UE may or may not transmit the PUSCH1 after the preset time length from the UL grant 2 ending position of the PUSCH1, which is not specifically limited.

An embodiment of the present invention further provides a channel scheduling method, applied to a terminal, as shown in fig. 6, including:

step 201: receiving first scheduling information of a first uplink channel sent by network side equipment;

step 202: receiving second scheduling information of a second uplink channel sent by network side equipment, wherein the priority of the second uplink channel is higher than that of the first uplink channel;

wherein the second scheduling information is received after the first scheduling information, and the first uplink channel and the second uplink channel overlap in time.

The first uplink channel and the second uplink channel are overlapped in time, the first uplink channel and the second uplink channel are partially overlapped in time, the first uplink channel and the second uplink channel are completely overlapped in time, and the interval between the end position of the second scheduling information and the start position of the second uplink channel and/or the first uplink channel is larger than or equal to a preset time length.

receiving the first scheduling information sent by the network side device through a first physical downlink control channel, where the first scheduling information schedules a first physical downlink shared channel or indicates to release a semi-persistent scheduling first SPS physical downlink shared channel, and the first scheduling information also indicates a terminal to feed back a hybrid automatic repeat request acknowledgement HARQ-ACK in the first physical uplink control channel, where the terminal may feed back the HARQ-ACK in the first physical downlink shared channel or the first scheduling information in the first physical uplink control channel;

receiving second scheduling information sent by the network side equipment through a second physical downlink control channel, wherein the second scheduling information schedules the second physical downlink shared channel or indicates to release a second SPS physical downlink shared channel, and the second scheduling information further indicates the terminal to feed back HARQ-ACK on the second physical uplink control channel, and the terminal can feed back HARQ-ACK of the second physical downlink shared channel or the second scheduling information on the second physical uplink control channel;

the second physical uplink control channel and the first physical uplink control channel overlap in time.

Optionally, the method further comprises:

and when the interval between the ending position of the second physical downlink control channel and the starting position of the first physical uplink control channel is greater than or equal to a preset time length, not transmitting the first physical uplink control channel.

Optionally, the method further comprises:

and when the interval between the ending position of the second physical downlink control channel and the starting position of the first physical uplink control channel is smaller than a preset time length, not transmitting the part of the first physical uplink control channel beyond the preset position, wherein the interval between the preset position and the ending position is the preset time length.

In order to ensure that the scheduling information with high priority can be scheduled in time and ensure that the terminal has enough time to cancel the transmission of the first physical uplink control channel, the first physical downlink shared channel uses the processing capability 1 of the physical downlink shared channel, the second physical downlink shared channel uses the processing capability 2 of the physical downlink shared channel, and the preset time length is determined by the processing time of the physical downlink shared channel corresponding to the processing capability 2 of the physical downlink shared channel.

receiving the first scheduling information sent by the network side equipment through a first uplink authorization message, wherein the first scheduling information indicates the terminal to transmit the first physical uplink shared channel;

receiving second scheduling information sent by the network side equipment through a second uplink authorization message, wherein the second scheduling information indicates the terminal to transmit the second physical uplink shared channel;

the second physical uplink shared channel and the first physical uplink shared channel overlap in time.

Optionally, the method further comprises:

and when the interval between the ending position of the second uplink authorization message and the starting position of the first physical uplink shared channel is greater than or equal to a preset time length, not transmitting the first physical uplink shared channel.

Optionally, the method further comprises:

and when the interval between the ending position of the second uplink authorization message and the starting position of the first physical uplink shared channel is smaller than a preset time length, not transmitting the part of the first physical uplink shared channel beyond the preset position, wherein the interval between the preset position and the ending position is the preset time length.

Taking a network side device as an example of a base station, in a specific embodiment, as shown in fig. 7, the base station schedules a PDSCH1 through a PDCCH1, and instructs the UE to feed back HARQ-ACK of a PDSCH1 on a PUCCH1, schedules a PDSCH2 with a higher priority through a PDCCH2 after the PDCCH1, and instructs the UE to feed back HARQ-ACK of a PDSCH2 on a PUCCH2, time domain resources of the PUCCH1 and the PUCCH2 overlap, and the UE must discard the PUCCH1 or the PUCCH2 because the UE cannot simultaneously transmit different PUCCHs. Assuming that the priority of HARQ-ACK corresponding to PDSCH2 is higher than the priority of HARQ-ACK corresponding to PDSCH1, when the time domain resources of PUCCH1 and PUCCH2 overlap, the UE will not transmit PUCCH1, and accordingly, the UE either discards HARQ-ACK corresponding to PDSCH1, transmits HARQ-ACK corresponding to PDSCH2 on PUCCH2, or multiplexes HARQ-ACK corresponding to PDSCH1 and HARQ-ACK corresponding to PDSCH2 on one channel.

However, the UE needs enough time to decode PDCCH2 and cancel transmission of PUCCH1, and therefore if the UE is required to completely not transmit PUCCH1, it is necessary that interval T3 between the end position of PDCCH2 and the start position of PUCCH1 is greater than or equal to a certain threshold. The threshold is related to UE processing capability, and in order to reduce the limitation on high priority PDSCH scheduling, when the UE is configured with two PDSCH processing capabilities (PDSCH processing capability 1 and PDSCH processing capability 2), the threshold should be defined according to the PDSCH processing capability of the UE, i.e. PDSCH processing capability 2, for example, the threshold is equal to PDSCH processing time N1 corresponding to PDSCH processing capability 2, where PDSCH processing capability 1 and PDSCH processing capability 2 may correspond to the same serving cell or different serving cells.

In another specific embodiment, as shown in fig. 8, the base station schedules PDSCH1 through PDCCH1 and instructs the UE to feed back HARQ-ACK of PDSCH1 on PUCCH1, schedules PDSCH2 with higher priority through PDCCH2 after PDCCH1, and instructs the UE to feed back HARQ-ACK of PDSCH2 on PUCCH2, where PUCCH1 and PUCCH2 overlap in time domain resources, and the UE must discard PUCCH1 or PUCCH2 because the UE cannot transmit different PUCCHs at the same time. Assuming that the priority of HARQ-ACK corresponding to PDSCH2 is higher than the priority of HARQ-ACK corresponding to PDSCH1, when the time domain resources of PUCCH1 and PUCCH2 overlap, the UE will not transmit PUCCH1, and accordingly, the UE either discards HARQ-ACK corresponding to PDSCH1, transmits HARQ-ACK corresponding to PDSCH2 on PUCCH2, or multiplexes HARQ-ACK corresponding to PDSCH1 and HARQ-ACK corresponding to PDSCH2 on one channel. In any case, the UE needs enough time to decode PDCCH2 and cancel transmission of PUCCH1, so at least the UE needs to be able to cancel PUCCH1 before transmitting PUCCH2, and the interval T3 from the PDCCH2 end position to the PUCCH2 start position needs to be greater than or equal to a certain threshold. The UE may transmit PUCCH1 within this threshold after PDCCH2 end position, but need to cancel PUCCH1 transmission after this threshold. The threshold is related to UE processing capability, and in order to reduce the limitation on high priority PDSCH scheduling, when the UE is configured with two PDSCH processing capabilities (PDSCH processing capability 1 and PDSCH processing capability 2), the threshold should be defined according to the PDSCH processing capability of the UE, i.e. PDSCH processing capability 2, for example, the threshold is equal to PDSCH processing time N1 corresponding to PDSCH processing capability 2, where PDSCH processing capability 1 and PDSCH processing capability 2 may correspond to the same serving cell or different serving cells.

In another embodiment, as shown in fig. 9, the base station schedules PUSCH1 transmission through UL grant 1, after UL grant 1, the base station sends UL grant 2 to the UE due to the higher priority service request, and schedules the UE to transmit PUSCH2, where PUSCH1 and PUSCH2 are in the same serving cell and overlap on time domain resources. Since the UE can transmit only one PUSCH in one serving cell at the same time due to restriction by PAPR or the like, the UE can transmit only one of them and discard the other in PUSCH1 and PUSCH 2. Assuming that the priority of PUSCH2 is higher than that of PUSCH1, the UE discards PUSCH1 with low priority and transmits PUSCH2 with high priority. Since the UE must be aware of the PUSCH2 transmission after decoding the UL grant 2, and the PUSCH2 and PUSCH1 resources overlap, and discard the PUSCH1, limited by the UE processing time, the UE may decode the UL grant 2 not immediately after receiving the UL grant 2, and stop the PUSCH1 transmission, but needs a certain processing time to decode the UL grant 2. Therefore, the base station is limited by a certain time when scheduling PUSCH2, i.e., the transmission time of UL grant 2 cannot be too late. For example, if the UE is not to transmit PUSCH1 at all, the time interval T4 from the end position of UL grant 2 to the start position of PUSCH1 is required to be greater than a certain threshold. This threshold is related to the UE processing capability, and in order to reduce the limitation on the high priority PUSCH scheduling, when the UE configures two PUSCH processing capabilities (PUSCH processing capability 1 and PUSCH processing capability 2) on the serving cell, the threshold should be defined according to the PUSCH high processing capability of the UE, i.e. PUSCH processing capability 2, for example, the threshold may be equal to the PUSCH preparation time corresponding to PUSCH processing capability 2.

In another embodiment, as shown in fig. 10, the base station schedules PUSCH1 transmission through UL grant 1, after UL grant 1, the base station sends UL grant 2 to the UE due to the higher priority service request, and schedules the UE to transmit PUSCH2, where PUSCH1 and PUSCH2 are in the same serving cell and overlap on time domain resources. Since the UE can transmit only one PUSCH in one serving cell at the same time due to restriction by PAPR or the like, the UE can transmit only one of them and discard the other in PUSCH1 and PUSCH 2. Assuming that the priority of PUSCH2 is higher than that of PUSCH1, the UE discards PUSCH1 with low priority and transmits PUSCH2 with high priority. Since the UE must be aware of the PUSCH2 transmission after decoding the UL grant 2, and the PUSCH2 and PUSCH1 resources overlap, and discarding the PUSCH1 is limited by the UE processing time, the UE may decode the UL grant 2 and stop PUSCH1 transmission instead of immediately after receiving the UL grant 2, but a certain processing time is required to decode the UL grant 2.

Therefore, the base station is limited by a certain time when scheduling PUSCH2, i.e., the transmission time of UL grant 2 cannot be too late. For example, if the UE is required to cancel transmission of PUSCH1 before transmission of PUSCH2, the time interval T4 from the end position of UL grant 2 to the start position of PUSCH2 needs to be greater than a certain threshold. Due to time constraints, the UE may transmit PUSCH1 within this threshold after the end position of UL grant 2, but may not transmit PUSCH1 outside this threshold after the end position of UL grant 2. This threshold is related to the UE processing capability, and in order to reduce the limitation on the high priority PUSCH scheduling, when the UE configures two PUSCH processing capabilities (PUSCH processing capability 1 and PUSCH processing capability 2) on the serving cell, the threshold should be defined according to the PUSCH high processing capability of the UE, i.e. PUSCH processing capability 2, for example, the threshold may be equal to the PUSCH preparation time corresponding to PUSCH processing capability 2.
