Referring to fig. 1, fig. 1 is a block diagram of a wireless communication system to which an embodiment of the present invention is applicable. The wireless communication system includes a terminal 11 and a network-side device 12. The terminal 11 may also be referred to as a terminal Device or a User Equipment (UE), where the terminal 11 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device, and the specific type of the terminal 11 is not limited in the embodiment of the present invention. The network-side device 12 may be a Base Station or a core network, wherein the Base Station may be a 5G or later-version Base Station (e.g., a gNB, a 5G NR NB, etc.), or a Base Station in other communication systems (e.g., an eNB, a WLAN access point, or other access points, etc.), or a location server (e.g., an E-SMLC or an lmf (location Manager function)), wherein the Base Station may be referred to as a node B, an evolved node B, an access point, a Base Transceiver Station (BTS), a radio Base Station, a radio Transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, or some other suitable terminology in the field, as long as the same technical effect is achieved, the base station is not limited to a specific technical vocabulary, and it should be noted that, in the embodiment of the present invention, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

The base stations may communicate with the terminals 11 under the control of a base station controller, which may be part of the core network or some of the base stations in various examples. Some base stations may communicate control information or user data with the core network through a backhaul. In some examples, some of the base stations may communicate with each other, directly or indirectly, over backhaul links, which may be wired or wireless communication links. A wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on the multiple carriers simultaneously. For example, each communication link may be a multi-carrier signal modulated according to various radio technologies. Each modulated signal may be transmitted on a different carrier and may carry control information (e.g., reference signals, control channels, etc.), overhead information, data, and so on.

The base station may communicate wirelessly with the terminal 11 via one or more access point antennas. Each base station may provide communication coverage for a respective coverage area. The coverage area of an access point may be divided into sectors that form only a portion of the coverage area. A wireless communication system may include different types of base stations (e.g., macro, micro, or pico base stations). The base stations may also utilize different radio technologies, such as cellular or WLAN radio access technologies. The base stations may be associated with the same or different access networks or operator deployments. The coverage areas of different base stations (including coverage areas of base stations of the same or different types, coverage areas utilizing the same or different radio technologies, or coverage areas belonging to the same or different access networks) may overlap.

The communication link in the wireless communication system may include an Uplink for carrying Uplink (UL) transmission (e.g., from the terminal 11 to the network side device 12), or a Downlink for carrying Downlink (DL) transmission (e.g., from the network side device 12 to the terminal 11), and a sidelink (SL, or vice link, side link, etc.) for carrying transmission between the terminal 11 and other terminals 11. The UL transmission may also be referred to as reverse link transmission, while the DL transmission may also be referred to as forward link transmission. Downlink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both. Similarly, uplink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both.

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), high-reliability Low Latency Communications (URLLC), mass-machine-type Communications (mtc); the scenes put forward the requirements of high reliability, low time delay, large bandwidth, wide coverage and the like for the system. For some UEs, different services may be supported, for example, the UE supports both URLLC low-latency high-reliability service and eMBB service with large capacity and high rate. New Radio (NR) systems may have overlapping transmissions on time domain resources because different channels may have different starting symbols and lengths. When one slot has multiple overlapped Physical Uplink Control Channels (PUCCHs) for transmission, the single carrier characteristic of the UE is destroyed, and the difference of the transmission power causes the deterioration of the channel estimation performance. In order to maintain the uplink single carrier characteristic, the situation is generally regarded as an overlap, and a corresponding overlap solution needs to be designed, and some information needs to be merged and discarded.

When one UE supports different services, such as URLLC and eMBB, simultaneously, because different services have different delay or reliability requirements, in order to ensure transmission of a high priority service, the UE shall distinguish priorities corresponding to different channels and/or signals, such as high priority or low priority, the channels and/or signals with different priorities may overlap on time domain resources, and the UE shall discard and/or cancel the low priority channel and/or signal.

In the related art, if different service types or priorities are not distinguished, when different channel time domain resources overlap, the UE multiplexes or discards according to a predefined rule, for example, when a PUCCH carrying a dynamic Hybrid Automatic Repeat reQuest acknowledgement (HARQ-ACK) and a PUCCH carrying periodic Channel State Information (CSI) overlap, the UE multiplexes the HARQ-ACK and the CSI on one PUCCH, and the PUCCH is determined according to a total load of the HARQ-ACK and the CSI and a physical uplink control channel resource indicator (PUCCH resource indicator, PRI) corresponding to the HARQ-ACK; for another example, when the time domain resources of the PUCCH and the Physical Uplink Shared Channel (PUSCH) overlap (except for a specific case, such as SR PUCCH and PUSCH without UL-SCH), the UE multiplexes the content carried by the PUCCH on the PUSCH for transmission. Meanwhile, due to hardware requirements, the UE multiplexing processing needs certain time requirements, and the related technology defines the time requirements which should be met when the PUCCH and the PUCCH or the PUCCH and the PUSCH are multiplexed.

In the related art, it is considered that one UE may simultaneously support different services, and the different services correspond to different service requirements, such as time delay, reliability, and the like. Therefore, a mechanism for marking the priority of the PUCCH/PUSCH channel is introduced, and specifically, the priority of a 2-level physical layer is introduced, namely high priority and low priority. For example, Scheduling Request (SR), configuration of a granted PUSCH (CG PUSCH), Semi-Persistent Scheduling (SPS) PDSCH and its released HARQ-ACK priority are Configured by Radio Resource Control (RRC) signaling, and are considered as low priority for periodic CSI (P-CSI) or Semi-Persistent CSI (SP-CSI) on PUCCH. For HARQ-ACK of dynamically scheduled PDSCH, dynamically scheduled PUSCH (DG PUSCH), aperiodic CSI (a-CSI)/SP-CSI on PUSCH, etc. are indicated by 1-bit field in corresponding scheduling Downlink Control Information (DCI). The priority of the PUCCH is then determined by the HARQ-ACK, SR and/or CSI it carries. When different channel time domain resources are overlapped, if the different channel time domain resources are the same priority, processing is carried out according to a predefined multiplexing rule, and if the different channel time domain resources are different priorities, the UE discards a channel with low priority and transmits a channel with high priority. If the channels with the same priority and the channels with different priorities exist, the UE processes the channels with the same priority according to a predefined multiplexing rule and then processes the channels with different priorities. When the UE processes different priority levels, the UE discards the low priority level, and also needs a certain processing time to transmit the high priority level channel, and the requirements for discarding and/or canceling time when the UE processes different priority level channels need to be defined.

In the related art, either the UE does not prioritize or prioritize the channels, but does not support multiplexing between channels of different priorities. If the priority is not distinguished, the UE will always multiplex different channels according to the established multiplexing rule, if the priority is distinguished, the low priority channel is always discarded under the overlapping scene, thus greatly influencing the transmission performance of the low priority channel. Therefore, there is a need for new solutions that can support both different priority packets and different priority channel multiplexing.

An embodiment of the present invention provides an uplink transmission processing method, which is applied to a terminal, and as shown in fig. 2, the method includes:

step 101: acquiring a transmission identifier of each uplink transmission, wherein the transmission identifier is used for indicating whether the uplink transmission supports multiplexing with other uplink transmissions when the uplink transmission is overlapped with other uplink transmissions on time domain resources;

step 102: and carrying out uplink transmission according to the transmission identifier.

In this embodiment, the terminal obtains the transmission identifier of each uplink transmission, and performs uplink transmission according to the transmission identifier of the uplink transmission, so that when multiple uplink transmissions are overlapped on the time domain resource, the problem of collision among the multiple uplink transmissions can be handled according to the transmission identifiers of the uplink transmissions according to a certain rule, the transmission performance of a channel can be ensured, and the effectiveness of the communication system can be improved.

The network side device may indicate or predefine the transmission identifier of each uplink transmission through an RRC message or DCI, and the terminal may obtain the transmission identifier of each uplink transmission after receiving the RRC message or DCI.

The transmission identifier of each uplink transmission may be determined by the transmission identifier of the resource of the uplink transmission or the content carried by the uplink transmission.

In an exemplary embodiment of the invention, the method further comprises:

acquiring the priority of each uplink transmission;

and carrying out uplink transmission according to the transmission identifier and the priority.

The network side device may indicate or predefine the priority of each uplink transmission through an RRC message or DCI, and the terminal may obtain the priority of each uplink transmission after receiving the RRC message or DCI.

The priority of each uplink transmission may be determined by the resource of the uplink transmission or the priority of the content carried by the uplink transmission. In this embodiment, whether uplink transmission supports Multiplexing with other uplink transmissions and whether uplink transmission according to priority is supported may be indicated by a Multiplexing/priority identifier (M/P), specifically, when the Multiplexing indicator is 1, it may be indicated that uplink transmission supports Multiplexing with other uplink transmissions, and when the Multiplexing indicator is 0, it may be indicated that uplink transmission does not support Multiplexing with other uplink transmissions; or when the priority indicator is 1, it may indicate that the uplink transmission supports the transmission by priority, and when the priority indicator is 0, it may indicate that the uplink transmission does not support the transmission by priority.

In an exemplary embodiment of the present invention, the performing uplink transmission according to the transmission identifier or performing uplink transmission according to the transmission identifier and the priority includes at least one of the following manners:

Specifically, a combination of any two of the four manners described above may be performed, and when the combination of any two of the four manners described above is performed, the following example may be employed:

in a specific example, the time domain resource overlapping between uplink transmissions with the same priority may be processed first, and then the time domain resource overlapping between uplink transmissions with different priorities may be processed. When the time domain resource overlapping between the uplink transmissions with the same priority is processed, the time domain resource overlapping between the uplink transmissions with the same transmission identifier can be processed first, and then the time domain resource overlapping between the uplink transmissions with different transmission identifiers can be processed; or processing the time domain resource overlapping between the uplink transmissions with the same channel type, and then processing the time domain resource overlapping between the uplink transmissions with different channel types; or processing the time domain resource overlap between the uplink transmissions according to the time sequence of the uplink transmissions.

Of course, a combination of any three of the above four ways or a combination of the four ways may also be performed. When the combination of the multiple modes is executed, time domain resource overlapping between uplink transmissions is sequentially processed according to uplink transmission parameters related to the multiple modes, wherein the uplink transmission parameters comprise channel types, priorities, transmission identifiers and time sequences, for example, the time domain resource overlapping between the uplink transmissions with the same channel types is processed firstly; when the time domain resource overlapping between the uplink transmissions with the same channel type is processed, the time domain resource overlapping between the uplink transmissions with the same priority is processed, and then the time domain resource overlapping between the uplink transmissions with different priorities is processed; when the time domain resource overlapping between the uplink transmissions with the same priority is processed, the time domain resource overlapping between the uplink transmissions with the same transmission identifier is processed, and then the time domain resource overlapping between the uplink transmissions with different transmission identifiers is processed; and when the time domain resource overlapping between the uplink transmissions with the same transmission identification is processed, the time domain resource overlapping between the uplink transmissions is processed according to the time sequence of the uplink transmissions, and so on.

The following further introduces the technical solution of the present invention by taking uplink transmission as an example and combining with specific embodiments:

example one

As shown in fig. 3, P represents priority indication, where P ═ 0 represents low priority and P ═ 1 represents high priority; m denotes a transmission indication multiplexing indicator, M-0 denotes that multiplexing is not supported, and M-1 denotes that multiplexing is supported. The HARQ-ACK PUCCH (i.e. the PUCCH carrying the HARQ-ACK) is indicated as a high priority channel according to the priority, and the CG PUSCH1 and the CG PUSCH2 are respectively different configuration authorized PUSCHs, and the priority levels of the two are respectively low priority and high priority. Meanwhile, the three channels are configured or indicated with corresponding M/P identifiers, where M ═ 1 (or 'Multiplexing') indicates that Multiplexing with other channels is allowed (Multiplexing), and M ═ 0 (or 'priority') indicates that Multiplexing with other channels is not supported, but priority transmission is supported (priority), as can be seen from fig. 3, the three channels all support Multiplexing. HARQ-ACK PUCCH is overlapped with CG PUSCH1, CG PUSCH2 in time domain, and CG PUSCH1 and CG PUSCH2 are not overlapped in time domain. The UE may adopt any one of the following processing methods:

embodiment 1: the UE processes the multiplexing between the channels with the same priority firstly, namely processes the multiplexing between the HARQ-ACK PUCCH and CG PUSCH2 with the same priority firstly, and the UE multiplexes the HARQ-ACK on CG PUSCH2 for transmission. Since the CG PUSCH1 and CG PUSCH2 time domain resources are not overlapped, the UE transmits CG PUSCH1 and CG PUSCH2, respectively.

Embodiment 2: the UE processes according to the assumption that all transmissions have the same priority or no priority. In fig. 3, a HARQ-ACK PUCCH and a plurality of PUSCHs are shown, and according to the related art, when a PUCCH overlaps with a plurality of PUSCH time domain resources, a UE selects a way of multiplexing a PUSCH. Assuming that subcarrier spaces (SCS) of different serving cells CC0, CC1, and CC2 are the same, PUSCH1 and PUSCH2 are in the same slot, and the UE selects, according to the serving cell index, a CG PUSCH1 with a small corresponding serving cell index to multiplex HARQ-ACK transmission on the PUSCH 1. Since the CG PUSCH1 and CG PUSCH2 time domain resources are not overlapped, the UE transmits CG PUSCH1 and CG PUSCH2, respectively.

Embodiment 3: the UE processes according to the time sequence, namely according to at least one of the time slot where the uplink transmission is located and the initial symbol in the time slot. As can be seen from FIG. 3, according to the time sequence, the HARQ-ACK PUCCH and CG PUSCH1 are overlapped first, and then the HARQ-ACK PUCCH and CG PUSCH2 are overlapped, the UE processes the overlapping of the HARQ-ACK PUCCH and CG PUSCH1 first and multiplexes the HARQ-ACK on the CG PUSCH1 for transmission. Since the CG PUSCH1 and CG PUSCH2 time domain resources are not overlapped, the UE transmits CG PUSCH1 and CG PUSCH2, respectively.

Example two:

as shown in fig. 4, P represents priority indication, where P ═ 0 represents low priority and P ═ 1 represents high priority; m denotes a transmission indication multiplexing indicator, M-0 denotes that multiplexing is not supported, and M-1 denotes that multiplexing is supported. The HARQ-ACK PUCCH is a feedback channel for carrying HARQ-ACK of the dynamically scheduled PDSCH, and the priority is low; CG PUSCH1 and CG PUSCH2 are different configuration authorized PUSCHs, and the priority of the configuration authorized PUSCHs is high. The corresponding M/P identifier of HARQ-ACK PUCCH and CG PUSCH2 is M-1 (or multiplexing), that is, multiplexing with other channels is allowed, and the M/P identifier of CG-PUSCH1 is M-0 (or multiplexing), that is, multiplexing with other channels is not allowed. It is assumed that two overlapping transmissions can be multiplexed for transmission on one channel only if the M/P identities of both transmissions are M. The UE may adopt any one of the following processing methods:

embodiment 1: UE firstly makes multiplexing between the transmission capable of being multiplexed, and then performs priortation, namely the UE firstly processes the time domain resource overlapping between a HARQ-ACK PUCCH and a CG PUSCH2, and multiplexes the HARQ-ACK to a CG PUSCH2 for transmission; after that, since the time domain resources of CG PUSCH1 and CG PUSCH2 are not overlapped, the UE transmits CG PUSCH1 and CG PUSCH2, respectively.

Embodiment 2: the UE processes the overlapped transmission according to the time sequence, as can be seen from FIG. 4, according to the time sequence, the HARQ-ACK PUCCH and CG PUSCH1 are overlapped firstly, then the HARQ-ACK PUCCH and CG PUSCH2 are overlapped, the UE processes the overlap between the CG PUSCH1 and the HARQ-ACK PUCCH firstly, and the CH PUSCH1 is not allowed to be multiplexed with other transmissions, so the UE discards the HARQ-ACK PUCCH transmission with low priority and transmits CG PUSCH 1. After that, since the time domain resources of CG PUSCH1 and CG PUSCH2 are not overlapped, the UE transmits CG PUSCH1 and CG PUSCH2, respectively.

Embodiment 3: the UE performs prioritization first, i.e. the UE processes the overlap between CG PUSCH1 and HARQ-ACK PUCCH first, which can guarantee the transmission of high priority channels. Since the CG PUSCH1 is not allowed to be multiplexed with other channels, the UE discards the HARQ-ACK PUCCH transmission with low priority, and after the CG PUSCH1 is transmitted, the UE transmits CG PUSCH1 and CG PUSCH2 respectively because the time domain resources of the CG PUSCH1 and CG PUSCH2 are not overlapped.

EXAMPLE III

As shown in fig. 5, P represents priority indication, where P ═ 0 represents low priority and P ═ 1 represents high priority; m denotes a transmission indication multiplexing indicator, M-0 denotes that multiplexing is not supported, and M-1 denotes that multiplexing is supported. The HARQ-ACK PUCCH is a feedback channel for carrying HARQ-ACK of the dynamically scheduled PDSCH, and the priority is high; CG PUSCH1 is a configuration authorization PUSCH, DG PUSCH2 is a dynamically scheduled PUSCH, and the priorities are all low priorities. The corresponding M/P identifier of the HARQ-ACK PUCCH and CG PUSCH1 is M-1 (or Multiplexing), that is, Multiplexing with other channels is allowed, and the M/P identifier of the DG-PUSCH2 is M-0 (or Multiplexing), that is, Multiplexing with other channels is not allowed. It is assumed that two overlapping transmissions can be multiplexed for transmission on one channel only if the M/P identities of both transmissions are M. The UE may process the data in any of the following manners:

embodiment 1: the UE firstly carries out multiplexing between the transmissions capable of being multiplexed and then carries out priortation, namely the UE firstly processes the time domain resource overlapping between the HARQ-ACK PUCCH and CG PUSCH1 and multiplexes the HARQ-ACK to CG PUSCH1 for transmission. Afterwards, since the time domain resources of the CG PUSCH1 and the DG PUSCH2 do not overlap, the UE transmits CG PUSCH1 and DG PUSCH2, respectively.

Embodiment 2: the UE processes the overlapping transmissions in time order, i.e., the UE processes the time domain resource overlap between CG PUSCH1 and HARQ-ACK PUCCH first, since both transmissions are allowed to be multiplexed with other transmissions, the UE multiplexes HARQ-ACK PUCCH onto CG PUSCH1 for transmission. After that, since the time domain resources of CG PUSCH1 and DG PUSCH2 are not overlapped, the UE transmits CG PUSCH1 and DG PUSCH2, respectively.

Embodiment 3: the UE performs prioritization first, and since DGPUSCH2 and HARQ-ACK PUCCH are both low priority, the UE processes time domain resource overlap between DGPUSCH2 and HARQ-ACK PUCCH first, and since DGPUSCH2 is not allowed to be multiplexed with other channels, the UE discards one of DGPUSCH2 and HARQ-ACK PUCCH, for example, discards DGPUSCH2 transmission, and transmits HARQ-ACK PUCCH. In addition, since the time domain resources of CG PUSCH1 and HARQ-ACK PUCCH are overlapped and both support multiplexing, the UE multiplexes HARQ-ACK on CG PUSCH1 for transmission.

Embodiment 4: the UE firstly processes the overlapping between the dynamically scheduled transmissions, namely the UE firstly processes the time domain resource overlapping between the DGPUSCH2 and the HARQ-ACK PUCCH, and the DGPUSCH2 is not allowed to be multiplexed with other channels, so the UE discards the DGPUSCH2 transmission with low priority and transmits the HARQ-ACK PUCCH. In addition, since the time domain resources of CG PUSCH1 and HARQ-ACK PUCCH are overlapped and both support multiplexing, the UE multiplexes HARQ-ACK on CG PUSCH1 for transmission.

Example four

As shown in fig. 6, P represents priority indication, where P ═ 0 represents low priority and P ═ 1 represents high priority; m denotes a transmission indication multiplexing indicator, M-0 denotes that multiplexing is not supported, and M-1 denotes that multiplexing is supported. The CSI PUCCH is a channel where periodic CSI is located, the M/P identifier of the RRC is configured or predefined to be M-0 (i.e. priority), and the M/P identifier of the CG PUSCH is M-1 (i.e. Multiplexing); the HARQ-ACK PUCCH overlaps with the CSI PUCCH and the CG PUSCH in time. Wherein, the M/P identifier of the HARQ-ACK PUCCH is M ═ 1 (i.e., Multiplexing). Wherein the three transmissions have no priority indication. The UE may adopt any one of the following processing methods:

embodiment 1: the UE processes the time domain resource overlap between transmissions of the same type first, that is, the UE processes the overlap between the PUCCH and the PUCCH first, and since CSI PUCCH does not support multiplexing (assuming that only two channels support multiplexing, the UE can multiplex the two channels), the UE discards one of HARQ-ACK PUCCH and CSI PUCCH, for example, the UE discards CSI PUCCH and transmits HARQ-ACK PUCCH. In addition, since the HARQ-ACK PUCCH overlaps in time with CG PUSCH1, the UE re-processes the time domain resource overlap between HARQ-ACK PUCCH and CG PUSCH1, and since both channels support multiplexing, the UE multiplexes HARQ-ACK onto CG PUSCH1 for transmission.

Embodiment 2: the UE performs multiplexing firstly, namely overlapping between the HARQ-ACK PUCCH and CG PUSCH1 is processed firstly, the HARQ-ACK is multiplexed onto CG PUSCH1 for transmission, and the CG PUSCH1 and the CSI PUCCH are transmitted by the UE respectively because of no overlapping between the CG PUSCH1 and the CSI PUCCH.

EXAMPLE five

As shown in fig. 7, P represents priority indication, where P ═ 0 represents low priority and P ═ 1 represents high priority; m denotes a transmission indication multiplexing indicator, M-0 denotes that multiplexing is not supported, and M-1 denotes that multiplexing is supported. The HARQ-ACK PUCCH is a HARQ-ACK feedback channel carrying the SPS PDSCH, and its M/P identifier is M ═ 1 (i.e., Multiplexing); the CSI PUCCH is a channel carrying periodic CSI, and M/P identifier thereof is M ═ 0 (i.e. priority); a CG PUSCH is a configuration authorization PUSCH, and the M/P identification of the CG PUSCH is M-1; the DG PUSCH is a dynamically scheduled PUSCH, and the M/P identifier thereof is M ═ 0. These 4 channels overlap in time, with two PUCCHs on the primary cell (Pcell), i.e., CC0, CG PUSCH on CC1, and DG PUSCH on CC 2. Where the four transmissions have no priority indication. The UE may process the following: the UE processes the time domain resource overlapping between the transmissions with the same type, namely processes the time domain resource overlapping between PUCCH and PUCCH first, multiplexes HARQ-ACK on CSI PUCCH for transmission, and then processes the reusable channel in CSI PUCCH, CG PUSCH and DG PUSCH first, namely processes the time domain resource overlapping between CSI PUCCH and CG PUSCH first, multiplexes CSIPUCCH and HARQ-ACK on CG PUSCH for transmission (namely when PUCCH and a plurality of PUSCHs are overlapped, UCI (except SR) on PUCCH is multiplexed on one of PUSCHs supporting multiplexing, if a plurality of PUSCHs support multiplexing, one PUSCHs is selected according to a certain rule, for example, the multiplexing rule when one PUCCH and a plurality of PUSCHs are overlapped in the related technology). Thereafter, since the CG PUSCH and the DG PUSCH are on different serving cells, the CG PUSCH and the DG PUSCH may be transmitted simultaneously.

EXAMPLE six

As shown in fig. 8, P represents priority indication, where P ═ 0 represents low priority and P ═ 1 represents high priority; m denotes a transmission indication multiplexing indicator, M-0 denotes that multiplexing is not supported, and M-1 denotes that multiplexing is supported. The UE schedules HARQ-ACK PUCCH on CC0, where the priority is high priority, and the corresponding M/P identifier is M ═ 1 (i.e., Multiplexing); meanwhile, the CC0 also has a CSI PUCCH periodically transmitted, and the M/P identifier corresponding to the low priority is M-1 (i.e., Multiplexing). Meanwhile, the CC0 also schedules a DC PUSCH, the priority of which is low, and the corresponding M/P identifier is M ═ 1 (or Multiplexing). The CG PUSCH is a configuration authorized PUSCH, the priority is a high priority, and the corresponding M/P identifier is M ═ 0 (or priority). The processing method of the UE may adopt: regardless of the priority or M/P identity of each channel, the UE handles overlap between channels of the same type (e.g., overlap between PUCCH and PUCCH, or overlap between PUSCH and PUSCH) first, and then overlap between channels of different types (e.g., overlap between PUCCH and PUSCH).

The UE respectively processes the HARQ-ACK PUCCH and the CSI PUCCH, time domain resources between the DG PUSCH and the CG PUSCH are overlapped, the HARQ-ACK PUCCH and the CSI PUCCH support multiplexing, the UE multiplexes the HARQ-ACK and the CSI on one PUCCH for transmission, and the HARQ-ACK and the CSI are still on the HARQ-ACK PUCCH after multiplexing, namely the UE multiplexes the CSI PUCCH on the HARQ-ACK PUCCH for transmission. Since CG PUSCH is high priority and DG PUSCH is low priority, only one PUSCH can be sent on one serving cell, then UE discards low priority DG PUSCH and transmits high priority CG PUSCH. And then, processing time domain resource overlapping between the PUCCH and the PUSCH, namely time domain resource overlapping between the HARQ-ACK PUCCH and the CG PUSCH, and multiplexing information (HARQ-ACK and CSI) on the HARQ-ACK PUCCH by the UE to be transmitted on the CG PUSCH because the two channels are high-priority channels and if M/P identification is only suitable for channels with different priorities and the channels with the same priority do not need to be identified according to the M/P identification. If the M/P identities only apply to channels of different priorities and indications of the same priority (i.e. overlapping channels, regardless of priority), then since the M/P identities of the two channels are different (assuming that the UE can multiplex only if both M/P identities are M ═ 1), the UE drops one of the CG PUSCH and HARQ-ACK PUCCH, e.g. drops the CG PUSCH, transmits the HARQ-ACK PUCCH,
