The relevant content related to the present application will be described first.

1. Uplink transmit channel switching

R16 introduces a mechanism of uplink transmit channel switching (uplink Tx switching, or UL Tx switching), i.e. one UE transmits at 2 Tx at the most, one carrier supports one uplink transmit channel (carrier 1), the other carrier supports two transmit channels (carrier 2), carrier 1 and carrier 2 are in different bands, by switching Tx to support switching of two modes, mode one: uplink double-flow transmission is carried out on carrier 2, and mode two: single stream transmission is performed on carrier 1 and/or carrier 2.

According to whether the uplink transmission of the carrier 1 and the carrier 2 is supported or not, the uplink transmission is divided into option1 (the network configuration high-level parameter uplink txswitching option-r16 is switchedUL, which indicates that the uplink transmission of the carrier 1 and the carrier 2 cannot be performed simultaneously) and option2 (the network configuration high-level parameter uplink txswitching option-r16 is switchedUL, which indicates that the uplink transmission of the carrier 1 and the carrier 2 can be performed simultaneously).

The UL Tx switching supported by R16 is as follows:

1. for dual connectivity (E-UTRA-NR Dual Connectivity, EN-DC) of evolved Global terrestrial radio Access (Evolved Universal Terrestrial Radio Access, E-UTRA) to NR, support option1 and option2, the protocol specifies the E-UTRA uplink carrier as carrier 1 and the NR carrier as carrier 2;

2. Supporting out-of-band carrier aggregation (inter-band Carrier Aggregation, inter-band CA), supporting option1 and option2, and configuring two carriers of carrier aggregation to be carrier1 or carrier 2 through a network;

3. supporting secondary uplink (supplementary uplink, SUL), only OPTION1, configuring SUL or UL as carrier1 or carrier 2 over the network.

UE reporting capability, supporting option1, option2, or both, by parameter uplink Txswitching-options support. The time switching gap required for UL Tx switching is reported by the parameter uplink txswitching period. And reporting the band supporting the downlink interrupt through the parameter uplink Txswitching-DL-interrupt.

The network high-level parameter uplinktxswitching option is used for configuring the UE to support option1 or option2.uplink txswitching is used to configure whether the serving cell (serving cell) is used for UL Tx switching. The uplink txswitch period location is used to configure a cell associated with a handover time, and is used to determine a location of the handover time. uplink txswitch carrier is used to configure the carrier as carrier1 or carrier 2 for determining the number of ports supported and the handover case (case).

The R17 phase expands the handover situation of inter-CA and SUL. First, a handover of 2Tx-2Tx is supported, i.e., a handover between cases where two Tx are supported for both carriers. Further, a Tx switch between having one carrier on band a and two consecutive carriers on band B (both carriers may be transmitted with the same Tx) is supported. And two new radio resource control (Radio Resource Control, RRC) parameters are introduced, one for indicating whether a 1Tx-2Tx or 2Tx-2Tx switching mode is used, thereby determining whether to use the 1Tx-2Tx or 2Tx-2Tx switching parameters; when the Tx state after UL Tx switch is not unique, a parameter is used to indicate that the Tx state is 1tx+1tx, or that the Tx state is 0tx+2tx. For example, when the uplinktxswitching period 2T-r17 is configured, the UE supports 2Tx-2Tx switching, and the configured switching time is determined by the uplinktxswitching period 2T-r17, and if the parameter is not configured (i.e., the value of the parameter is null), the configured switching time is determined by the uplinktxswitching period-r 16. It is noted that the handover cases supported by the two modes 1Tx-2Tx and 2Tx-2Tx are partially overlapping, i.e. some handover cases may belong to either 1Tx-2Tx or 2Tx-2Tx, except that the handover parameters will be different depending on the mode.

When uplink Tx switching is triggered, additional UL Tx switching time is required for the following cases, including processing time for physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) transmission, aperiodic sounding reference signal (Sounding Reference Signal, SRS) transmission, physical downlink control channel (Physical Downlink Control Channel, PDCCH) triggered physical random access channel (Physical Random Access Channel, PRACH) transmission, and transmission of channel state information (Channel State Information, CSI). Wherein the preparation process time of the PUSCH transmission is T _proc,2 ＝max((N ₂ +d _2,1 )(2048+144)·κ2 ^-μ T _C +T _switch ,d _2,2 )，N ₂ Mu of PDCCH carrying scheduling downlink control information (Downlink Control Information, DCI) _DL And μ of transmitted PUSCH _UL Corresponding larger processing time determination (different sub-carrier space (SCS) corresponding to different processing time), T _switC h is the time of UL Tx switching reported by the UE; notably, for option2, μ of inter-band CA _UL ＝min(μ _UL,carrier1 ,μ _UL,carrier2 )。

2. Restriction of terminals during UL Tx switching

In the UL Tx switching procedure, the terminal has the following limitations:

the terminal does not expect to transmit on the carrier or band that is switching during the switching time.

When a start time is T ₀ Uplink transmission of (a) triggers UL Tx switching, then at T ₀ -T_ _offset After that, the terminal does not expect to cancel the UL Tx switching, or T ₀ -T_ _offset Post-scheduling other uplink transmissions and triggering at T ₀ Any other new upstream switch that was previously initiated, t\u _offset Is the processing time of the uplink transmission.

The terminal does not expect SCS to be μ in the subcarrier spacing _UL ＝max(μ _UL,carrier1 ,μ _UL,carrier2 ) More than one UL Tx switching is performed in one slot (slot), where μ _UL,carrier1 For the subcarrier spacing, mu, of the uplink transmission before the switching time _UL,carrier2 Is the subcarrier spacing of the uplink transmission after the switching time.

The related art performs UL Tx switching on2 bands only, and R18 introduces UL Tx switching of more than 2 bands (3, 4 bands). How to determine T for the time of uplink transmission of additional UL Tx switching, especially option2 of inter-band CA, when uplink transmission triggers UL Tx switching of more than 2 bands _proc,2 It needs to be determined, and the limitation of the terminal in UL Tx switching varies with the increase of the number of bands.

Fig. 2 is a diagram illustrating UL Tx switching performed on 4 bands by a terminal in the related art. As shown in fig. 2, from (1 Tx) cc1+ (1 Tx) CC2 to (1 Tx) cc3+ (1 Tx) CC4, carriers before and after switching of two Tx are different, 1Tx is switched from CC1 to CC3, and one Tx is switched from CC2 to CC4, according to the prior art, UE cannot transmit at switching period 1 and switching period 2, so that transmission of CC3 may be affected.

Fig. 3 is a diagram illustrating UL Tx switching performed on 3 bands by a terminal in the related art. As shown in fig. 3, switch from (1 Tx) cc1+ (1 Tx) CC2 to (2 Tx) CC3, t\u _offset，1 Obtained from SCS of CC1 and CC3, T/u _offset，2 Obtained from SCS of CC2 and CC 3. UL Tx switching is performed twice in switching gap (assumed to be 35 us), contrary to the provision that UL Tx switching cannot be performed more than once in one slot of the prior art (assumed to be 71us corresponding to 15 kHz).

Therefore, how to implement Tx handover of 3 bands or 4 bands and perform normal uplink transmission needs to be solved. In order to solve the above problems, embodiments of the present application provide a processing method, a terminal, and a network side device for transmitting channel switching.

The following describes in detail, by means of some embodiments and application scenarios thereof, a processing method for switching a transmission channel, a terminal, and a network side device provided in the embodiments of the present application with reference to the accompanying drawings.

Fig. 4 is a flow chart of a processing method for switching a transmission channel according to an embodiment of the present application. As shown in fig. 4, the method includes:

step 400, the terminal determines a first time domain position corresponding to N transmissions based on a first transmission in the N transmissions;

In the embodiments of the present application, the transmission may include a data channel/control channel/reference signal/random access channel, etc.

It can be understood that, based on the first transmission in the N transmissions, the terminal determines the first time domain positions corresponding to the N transmissions triggering the transmission channel switching, where the first time domain positions corresponding to the respective transmissions are the same, and the other transmission is not started in the Tx switching process of one transmission, so that the normal transmission in the Tx switching process can be ensured, the complexity of the terminal is reduced, and the throughput is improved.

It should be noted that, the method provided in the embodiment of the present application is not limited to 3 or 4 bands, but may be applied to a larger number of bands, and normal transmission in the Tx handover process between 3 or 4 or more bands may be implemented.

Optionally, the first time domain position is a starting time of the first transmission, or a starting position of a time unit where the first transmission is located.

The time unit comprises a time slot/subframe/sub-time slot sub-slot and the like.

Optionally, the N transmissions include at least one of:

n uplink transmissions;

n sidelink transmissions;

n scheduled transmissions;

transmission of N configurations;

N ₁ scheduled transmission and N ₂ Transmission of a configuration, where N ₁ +N ₂ ＝N。

It is to be appreciated that the N transmissions can be N uplink transmissions, N SL (SideLink) transmissions, N scheduled transmissions (e.g., N scheduled uplink transmissions, N scheduled SideLink transmissions), N configured transmissions (e.g., N configured uplink transmissions, N configured SideLink transmissions), or N ₁ Scheduled transmission and N ₂ Transmission of a configuration, where N ₁ +N ₂ N, e.g., N transmissions include scheduled UL and certain UL transmissions (e.g., configured grant (PUSCH, SRS, PUCCH, PRACH, etc)) of a particular/limit.

Optionally, the N transmissions satisfy a first condition, the first condition including at least one of:

a) The N transmissions other than the first transmission overlap with the first transmission in the time domain;

b) The difference between the start or end position of the other transmission than the first transmission among the N transmissions and the start or end position of the first transmission is within a first range;

c) The difference between the start or end positions of the other transmissions except the first transmission and the start position of the time unit where the start or end position of the first transmission is located in the first range;

For example, the time range of the first transmission is [ T1, T2], then the time range of the other transmissions is [ T1- Δt1, t2+Δt2], where Δt1, Δt2 are the first duration, the second duration, Δt1, Δt2, respectively, may be determined by a protocol convention or a network configuration or terminal.

d) And receiving second information in a first time window after a first information receiving moment or in a first time window at least comprising the first information, wherein the first information is used for scheduling or configuring the first transmission, and the second information is used for scheduling or configuring any transmission in other than the first transmission in the N transmissions.

It will be appreciated that when the terminal receives the first information, where the first information is used to schedule or configure the first transmission, for example, DCI, the following description uses information as DCI, including but not limited to DCI, and may further include RRC signaling or sidelink control information (SideLink control information) SCI, etc., the first time window, that is, the first time domain position T0 of the transmission of the information schedule or configuration within the first time window is determined to be the same.

The first time window may be a time window including at least the first information after the first information reception time.

Optionally, the length of the first time window is defined by a protocol or is set by a network or reported by a terminal.

For example, the protocol specifies that the value of the first time window is different for different SCSs, which may be SCS of the carrier on which the first information is located, or SCS of the carrier on which the transmission of the first information is scheduled or configured.

For another example, the network configures or the UE reports the number of antenna ports scheduled for different first information, or the number of carriers scheduled for the first information, or the configured Tx switching pattern, where the values of the first time windows are different.

Optionally, the starting position of the first time window is the receiving time of the first information, that is, the starting position of the first information, the ending position of the first time window is the position of the first time domain position corresponding to the first transmission, which is shifted forward by the preparation process duration corresponding to the first transmission, that is, T0-t_offset, where T0 is the first time domain position corresponding to the first transmission, may be the starting time of the first transmission, or the starting position of the time unit where the first transmission is located, and t_offset is the preparation process duration corresponding to the first transmission.

Optionally, the length of the first time window is determined according to at least one of:

The subcarrier spacing of the carrier wave where the first information is located;

a subcarrier spacing of the carrier wave where the first transmission is located;

parameters of the first information schedule;

the type of transmit channel switching;

and a mode of switching the configured transmission channel.

For example, the length of the first time window is related to the SCS of the carrier in which the first DCI is located, or the SCS of the carrier in which the transmission (i.e., the first transmission) scheduled by the first DCI is located.

Wherein the parameters of the first information schedule include at least one of: the number of antenna ports, the number of carriers, the number of frequency bands, etc. of the first information schedule.

The length of the first time window is also related to the type of transmit channel switch, which may include the following:

type one, similar to R16/17UL Tx switching between 2 bands, e.g., 1Tx-2Tx switching between a first band 1Tx and a second band 2Tx, includes Tx switching between:

type two, similar to R16/17UL Tx switching between 2 frequency bands, e.g., 2Tx-2Tx switching, where 2Tx switches from a first frequency band to a second frequency band, including Tx switching between:

type three UL Tx switches over 3 or 4 frequency bands, e.g. 1Tx switches from the first frequency band to the second frequency band, while another Tx remains in the third frequency band:

Type four UL Tx switches over 3 or 4 frequency bands, e.g. 1 Tx and another T _X Switching from the first frequency band and the second frequency band to the third frequency band, respectively, and vice versa:

type five, UL Tx handover specific to 4 frequency bands, e.g. T _X The handover involves two source bands and two other target bands:

the mode of the configured transmit channel switching includes: switchedUL, dualUL.

Optionally, the first transmission is the transmission with the earliest starting time in the N transmissions, or the first transmission is the transmission scheduled or configured by the first information received before the first time window.

It may be understood that, the first transmission is the transmission with the earliest start time among the N transmissions, and then the first time domain position corresponding to the first transmission is the start time of the transmission with the earliest start time among the N transmissions, and the first time domain positions corresponding to the respective transmissions among the N transmissions are all the start times of the first transmission.

For example, the first time window includes DCI1, DCI2, where the starting moments of the transmissions scheduled by DCI1, DCI2 are T1, T2, respectively, and T1> T2, and then the first time domain position t0=t2.

Or the first time domain position corresponding to each of the N transmissions is the start time of the transmission of the first information schedule or configuration received before the first time window.

Optionally, the method further comprises:

the terminal determines preparation process duration corresponding to N transmissions based on a first transmission in the N transmissions;

the preparation process duration corresponding to any transmission in the other transmissions except the first transmission in the N transmissions is the same as the preparation process duration corresponding to the first transmission.

It can be understood that, based on the first transmission in the N transmissions, the terminal determines the first time domain position T0 and the preparation process duration t_offset corresponding to the N transmissions triggering the transmission channel switching, where the first time domain positions corresponding to the respective transmissions are the same, and the preparation process durations corresponding to the respective transmissions are the same, so that normal transmission in the Tx switching process can be ensured, the complexity of the terminal is reduced, and the throughput is improved.

Optionally, the preparation process duration is related to at least one of:

scheduling or configuring a subcarrier interval of a carrier wave where the first information of the first transmission is located;

a subcarrier interval for scheduling or configuring a carrier wave in which information of each transmission in the N transmissions is located in a first time window;

subcarrier spacing of carriers where the N transmissions scheduled or configured in the first time window are located;

The number of antenna ports corresponding to the N transmissions scheduled or configured in the first time window;

and a mode of switching the configured transmission channel.

Optionally, the value of the preparation procedure duration t_offset is related to the configured Tx switching mode, for example, only when configured as dualUL, the uplink SCS of the carrier on which the DCI scheduled transmission (after Tx switching) is located is the minimum or maximum value of SCS of all configured carriers.

Optionally, the preparation process duration t_offset is determined according to a subcarrier interval of the carrier before and after the transmission channel switching corresponding to at least part of the information in the first time window.

Optionally, according to the preparation process duration t_offset determined by SCS of the carrier wave before and after Tx switching corresponding to at least part of the information in the first time window, the maximum value/minimum value in t_offset obtained for each piece of information in the at least part of the information is obtained.

Optionally, the preparation process duration is determined according to a subcarrier interval of carriers before and after switching of a transmission channel corresponding to at least part of information in the first time window, including:

and the preparation process time length is determined according to the subcarrier interval of the downlink carrier wave where each piece of information in the at least part of information is located and the uplink subcarrier interval of the carrier wave where each piece of information in the at least part of information is scheduled or configured to be transmitted.

It will be appreciated that the preparation procedure duration is determined based on at least a portion of the SCS of the downlink carrier on which each message is located, and at least a portion of the SCS of the uplink carrier on which each message is scheduled/configured for transmission (after Tx handoff) of the carrier (the maximum or minimum value of the SCS of multiple carriers if multiple carriers are scheduled).

For example, the determined preparation process duration t_offset is the maximum/minimum value of t_offset obtained for each DCI. Each DCI meeting the first condition in the first time window obtains a value of t_offset according to SCS of carriers before and after Tx switching. Specifically, the method is determined by SCS of downlink carrier where DCI is located and uplink SCS of carrier where DCI scheduled transmission (after Tx switching) is located (maximum value or minimum value of SCS of multiple carriers if multiple carriers are scheduled), and T is calculated by referring to the following formula _proc,2 The value of t_offset:

if the first uplink symbol in the PUSCH allocation of the transport block includes a UE-specific demodulation reference signal (UE-specific DeModulation Reference Signal, DM-RS), the symbol is shifted by a slot offset K ₂ And K _offset( If configured), and the start S and length L of PUSCH allocation are indicated by "time domain resources" to schedule allocation of DCI, including the effect of time advance, not earlier than symbol L ₂ Wherein L is ₂ Defined as the next uplink symbol, whose CP starts after the end of the last symbol of the PDCCH receiving DCI carrying the scheduled PUSCH, the UE shall send a transport block. When a PDCCH candidate is associated with a search space set configured with searchspacing linking, in order to determine the last symbol of a PDCCH carrying DCI scheduling PUSCH, a PDCCH candidate ending later in time of the two configured PDCCH candidates is used.

N2 is based on μ of UE handling capacities 1 and 2 in tables 6.4-1 and 6.4-2, respectively, where μ corresponds to T _proc,2 One at maximum (μdl, μul), where μdl corresponds to the subcarrier spacing of the downlink transmitting PDCCH carrying DCI scheduled PUSCH, μul corresponds to the subcarrier spacing of the uplink channel to transmit PUSCH, and k is at [4, ts 38.211]Is defined in section 4.1.

D if the first symbol of the PUSCH allocation contains only DM-RS _2,1 =0, otherwise, d _2,1 ＝1。

The method of claim 27, wherein the preparation process duration is determined based on a first uplink subcarrier spacing and a first downlink subcarrier spacing, the first uplink subcarrier spacing and the first downlink subcarrier spacing being determined based on information within a first time window;

wherein the first uplink subcarrier spacing comprises at least one of:

maximum/minimum value of subcarrier spacing of the configured uplink carrier;

33. The method of claim 27, wherein the preparation process duration comprises a first time component, the first time component being a time component resulting from a transmit channel switch;

34. The method according to any of claims 19-33, wherein the network side device does not schedule or configure a transmission triggering a transmit channel switch after the first time domain position after the end position of the first time window or after a second time domain position, the second time domain position being a position shifted forward by the preparation procedure duration by the first time domain position.

35. The method according to any of claims 22-33, wherein the network side device sends a transmission channel switch trigger instruction within the first time window no more than a preset number of times, the preset number of times being related to subcarrier spacing.

36. A processing apparatus for switching transmission channels, comprising:

37. A processing apparatus for switching transmission channels, comprising:

a first processing unit for configuring and/or scheduling N transmissions;

38. A terminal comprising a processor and a memory storing a program or instructions executable on the processor, which when executed by the processor, performs the steps of the method of processing a transmit channel switch as claimed in any one of claims 1 to 18.

39. A network side device comprising a processor and a memory storing a program or instructions executable on the processor, which when executed by the processor, implement the steps of the method of processing transmit channel switching as claimed in any one of claims 19 to 35.

40. A readable storage medium, wherein a program or instructions is stored on the readable storage medium, which when executed by a processor, implements the method of processing a transmission channel switch according to any one of claims 1 to 18, or the steps of the method of processing a transmission channel switch according to any one of claims 19 to 35.
