Description

Conflict processing method and device

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to a conflict processing method and device.

Background

In a New Radio (NR) system, a User Equipment (UE) may support services of different service types, for example, may support services with low latency and high reliability, and may also support services with high capacity and high rate.

In general, since different channels have different starting symbols and lengths, transmission resources corresponding to the different channels may overlap in the time domain. In the related art, if there are cases where transmission resources of different uplink transmissions overlap in the time domain, if the different uplink transmissions have different priorities, the UE cancels the uplink transmission with a low priority, and ensures the uplink transmission with a high priority. In addition, in the unlicensed band (unlicensed spectrum), before uplink transmission, the UE generally needs to detect whether the channel is empty, and if the channel is empty, the UE can access the channel for uplink transmission, and if the channel is busy, the UE cannot access the channel.

However, in the above procedure, if the UE detects that the channel corresponding to the high priority transmission is busy after canceling the low priority uplink transmission, the UE cannot perform the high priority uplink transmission. Thus, even if the channel corresponding to the low priority transmission is empty at this time, the UE cannot perform the low priority transmission, thereby reducing the probability of the UE accessing the channel.

Disclosure of Invention

The embodiment of the invention provides a conflict processing method and device, which can solve the problem that the probability of UE accessing to a channel can be reduced in the process of overlapping time domain resources.

In order to achieve the above purpose, the embodiment of the invention adopts the following technical scheme:

in a first aspect of an embodiment of the present invention, a method for processing a collision is provided, applied to a UE, where the method includes: under the condition that the time domain resources of the first uplink transmission and the time domain resources of the second uplink transmission overlap, the first uplink transmission and the second uplink transmission are processed according to uplink transmission information, wherein the uplink transmission information is information corresponding to the first uplink transmission and the second uplink transmission; the uplink transmission information includes any one of the following: channel access parameters; priority of uplink transmission and channel access parameters; the starting time domain position of the uplink transmission.

In a second aspect of the embodiments of the present invention, a conflict processing apparatus is provided, where the apparatus may include a processing module; the processing module is used for processing the first uplink transmission and the second uplink transmission according to uplink transmission information under the condition that the time domain resources of the first uplink transmission and the time domain resources of the second uplink transmission overlap, wherein the uplink transmission information is corresponding information of the first uplink transmission and the second uplink transmission; the uplink transmission information includes any one of the following: channel access parameters; priority of uplink transmission and channel access parameters; the starting time domain position of the uplink transmission.

A third aspect of an embodiment of the present invention provides a UE, the UE comprising a processor, a memory and a computer program stored on the memory and executable on the processor, the computer program implementing the steps of the conflict handling method in the first aspect described above when executed by the processor.

In a fourth aspect of embodiments of the present invention, there is provided a computer readable storage medium having stored thereon a computer program which, when executed by a processor, implements the steps of the conflict handling method as described in the first aspect.

In the embodiment of the invention, under the condition that the time domain resource of the first uplink transmission and the time domain resource of the second uplink transmission overlap, the UE can process the first uplink transmission and the second uplink transmission according to the uplink transmission information. The uplink transmission information is information corresponding to the first uplink transmission and the second uplink transmission. Since the uplink transmission information may include any one of the following: channel access parameters; priority of uplink transmission and channel access parameters; the starting time domain position of the uplink transmission. Therefore, the UE can determine how to process the first uplink transmission and the second uplink transmission of the time domain resource conflict by combining the channel access parameter, or the priority of the uplink transmission and the channel access parameter, or the starting time domain position of the uplink transmission.

Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

Some concepts and/or terms related to the conflict processing method and apparatus provided in the embodiments of the present invention are explained below.

1. Time domain overlapping of transmission resources (otherwise known as time domain collision)

Future 5G mobile communication systems need to accommodate more diverse scenarios and service requirements than previous mobile communication systems. The main scenarios of 5G include enhanced mobile broadband (enhanced mobile broad band, emmbb), large-scale machine-like communication (massive machine type communications, mctc), and ultra-reliable low-delay communication (ultra-reliable and low latency communications, URLLC), which place high reliability, low latency, large bandwidth, wide coverage, etc. demands on mobile communication systems. The UE may support different services, for example, the UE may support both low latency and highly reliable URLLC services and may support high capacity and high rate eMBB services. New Radio (NR) systems may overlap in time domain of transmission resources because different channels may have different starting symbols and lengths. In general, in order to maintain the uplink single carrier characteristic, when one slot has a plurality of overlapped uplink transmission resources for transmission, the single carrier characteristic of the UE is destroyed, and the difference in transmission power may cause degradation of channel estimation performance. For this situation, which is often considered a conflict, it is necessary to design a corresponding conflict resolution, and to merge or discard some information.

2. Uplink transmission

A physical uplink control channel (physical uplink control channel, PUCCH) transmitted by the UE.

A physical uplink shared channel (physical uplink shared channel, PUSCH) transmitted by the UE.

Physical random access channel (physical random access channel, PRACH) transmitted by the UE.

Sounding reference signals (sounding reference signal, SRS) for channels transmitted by the UE.

3. PUCCH and PUSCH collision handling

In NR R15, in one PUCCH group (PUCCH group), no PUCCH and PUSCH simultaneous transmission is supported, whether PUCCH and PUSCH are in the same serving cell or different serving cells. When the PUCCH and PUSCH time domain resources overlap (including partial time domain resource overlap and full time domain resource overlap), the UE may discard or combine according to the corresponding rule if a certain time requirement is met.

For example, if the PUCCH carrying the scheduling request (scheduling Request, SR) and the PUSCH carrying no uplink shared channel (uplink shared channel, UL-SCH) overlap in time domain, the UE discards the PUSCH and transmits the PUCCH, or the UE multiplexes uplink control information (uplink control information, UCI) (except SR) carried on the PUCCH into the PUSCH for transmission. If PUCCH 1 and PUSCH 2 carrying hybrid automatic repeat request acknowledgement (hybrid automatic repeat request acknowledgement, HARQ-ACK) or carrying channel state information (channel state information, CSI) overlap, the UE multiplexes HARQ-ACK/CSI carried on PUCCH 1 into PUSCH 2 for transmission.

Specifically, the UE first processes the time domain resource overlapping (if any) between multiple PUCCHs, and the result obtained by the processing is one or more PUCCHs with non-time domain resource overlapping, then the UE processes the time domain resource overlapping between the PUCCHs and the PUSCHs, if the PUCCHs overlap only one PUSCH, the UE multiplexes UCI (excluding SR) in the PUSCH, and if the PUCCHs overlap only multiple PUSCHs, the UE selects one PUSCH for multiplexing according to a first multiplexing priority rule in the related art, where the first multiplexing priority rule is as follows:

priority 1: PUSCH carrying Aperiodic channel state information (a-CSI).

Priority 2: PUSCH with earliest starting slot.

Priority 3: dynamically scheduled PUSCH > configures an authorized PUSCH or a semi-persistent PUSCH.

Priority 4: PUSCH with small serving cell index (index) the PUSCH with large serving cell index.

Priority 5: PUSCH with early transmission symbol > PUSCH with late transmission symbol.

In NR R16 studies, a 2-level priority indication of the physical layer is introduced, considering the different requirements of different services, where transmission of PUCCH and PUSCH introduce transmission priority identification.

Specifically, the transmission priority of the PUCCH is determined by the priority of UCI it carries. For example, the priority of SR is configured by radio resource control (radio resource control, RRC), the periodic CSI and semi-persistent CSI (SP-CSI) priorities are predefined as low priority, and the priority of HARQ-ACKs is indicated by their corresponding DCI or determined according to the configuration of semi-persistent scheduling (semi-persistent scheduling, SPs). The transmission priority of PUSCH is indicated by the scheduling downlink control information (downlink control information, DCI) corresponding to PUSCH, and for PUSCH with configuration grant, its priority is configured by RRC.

When the time domain resources of the PUCCH and the PUCCH overlap or the time domain resources of the PUCCH and the PUSCH overlap, the UE processes the transmission with the same priority (the rule is the same as R15) firstly, then processes the transmission with different priorities, and when the transmission with different priorities is processed, the UE cancels the transmission (or discarding) of the uplink resource with the low priority and the transmission of the uplink resource with the high priority under the condition of meeting a certain time requirement.

4. Unlicensed frequency bands

In future communication systems, unlicensed bands (unlicensed bands) may be used as a complement to licensed bands (licensed bands) to help operators expand services. To keep pace with NR deployment and maximize as much as possible unlicensed access based on NR, unlicensed bands may operate in the 5GHz,37GHz and 60GHz bands. The large bandwidth of the unlicensed band (80 MHz or 100 MHz) can reduce the implementation complexity of the network device and the UE. Since unlicensed bands are shared by multiple radio access technologies (radio access technology, RAT), such as WiFi, radar, long term evolution-licensed-assisted access (LTE-LAA), etc., unlicensed bands must be used in certain countries or regions in compliance with rules (regulation) to ensure that all devices can use the resources fairly, such as listen-before-talk (listen before talk, LBT), maximum channel occupancy time (maximum channel occupancy time, MCOT), etc.

Before the transmitting node needs to send information, the transmitting node (which may be a base station, UE, wiFi AP, etc.) needs to do channel idle estimation (clear channel assess, CCA) or extended channel idle estimation (extended clear channel assess, eCCA) to listen to the channel, i.e. perform Energy Detection (ED). When the energy is below a certain threshold, the channel is determined to be empty and the party can start transmission. After the transmission node starts transmission, the occupied channel time COT cannot exceed MCOT. In the prior art, an access node (e.g., UE) performs LBT in units of 20MHz bandwidth, corresponding to one sub-band or one resource block set (resource block set, RB set), and when the channel bandwidth is an integer multiple of 20MHz, the UE needs to perform LBT in multiple sub-bands/RB sets, respectively.

The channel access types currently explicitly available for 5G unlicensed communication systems are the following:

(1)LBT Cat 1:

the type 2C channel access (channel access) in the corresponding protocol is directly transmitted without any detection (sending), and it is necessary to use the channel in the case that the interval of transmission transition is less than 16us when the channel has been acquired.

(2)LBT Cat 2：

16us corresponds to type 2B channel access in the protocol, channel interception of 16us is performed, 25us corresponds to type2A channel access in the protocol, channel interception of 25us is performed, a specific signal acquisition channel can be used, and the maximum continuous transmission length should be smaller than a certain value, for example, 1ms.

(3)LBT Cat 4：

And (3) corresponding to the type 1 channel access in the protocol, carrying out channel interception integrating random back-off, setting different access priority grades (channel access priority class) of different channels, and finally obtaining different maximum lengths of the channels and then transmitting.

The embodiment of the invention provides a conflict processing method and device, wherein when time domain resources of first uplink transmission and time domain resources of second uplink transmission overlap, UE can process the first uplink transmission and the second uplink transmission according to uplink transmission information. The uplink transmission information is information corresponding to the first uplink transmission and the second uplink transmission. Since the uplink transmission information may include any one of the following: channel access parameters; priority of uplink transmission and channel access parameters; the starting time domain position of the uplink transmission. Therefore, the UE can determine how to process the first uplink transmission and the second uplink transmission of the time domain resource conflict by combining the channel access parameter, or the priority of the uplink transmission and the channel access parameter, or the starting time domain position of the uplink transmission.

The conflict processing method and the conflict processing equipment provided by the embodiment of the invention can be applied to a communication system. The method and the device can be particularly applied to the uplink transmission process of the UE based on the communication system.

The embodiment of the invention can be applied to various communication systems, such as a 5G communication system, a future evolution system or other communication systems. Various application scenarios may be included, such as machine-to-machine (M2M), D2M, enhanced mobile internet (eMBB), and ultra-high reliability and ultra-low latency communication (uilllc) scenarios. The specific requirements can be determined according to actual use, and the embodiment of the invention is not limited.

Fig. 1 is a schematic diagram of an architecture of a communication system according to an embodiment of the present invention. As shown in fig. 1, the communication system may include a UE 01 and a network device 02. Wherein a connection and communication may be established between the UE 01 and the network device 02.

A UE is a device that provides voice and/or data connectivity to a user, a handheld device with wired/wireless connection capabilities, or other processing device connected to a wireless modem. The UE may communicate with one or more core network devices via a radio access network (radio access network, RAN). The UE may be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal, or a portable, pocket, hand-held, computer-built-in or vehicle-mounted mobile device that exchanges voice and/or data with the RAN, e.g., a personal communication service (personal communication service, PCS) phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a wireless local loop (wireless local loop, WLL) station, a personal digital assistant (personal digital assistant, PDA) or the like. The UE may also be referred to as a User Agent (User Agent), a terminal device, or the like. As an example, in the embodiment of the present invention, fig. 1 illustrates that the UE is a mobile phone.

The network device may be a base station. A base station is a device deployed in a RAN for providing wireless communication functionality for UEs. The base stations may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems employing different radio access technologies, the names of devices with base station functionality may vary, for example, in third generation mobile communication (3G) networks, referred to as base stations (nodebs); in a long term evolution (long term evolution, LTE) system, referred to as evolved NodeB, eNB or eNodeB; in fifth generation mobile communication (5G) networks, referred to as gNB, etc. As communication technology evolves, the name "base station" may change.

The execution main body of the conflict processing method provided by the embodiment of the invention can be the UE, or can be a functional module and/or a functional entity capable of implementing the conflict processing method in the UE, and the embodiment of the invention is not limited, specifically can be determined according to actual use requirements. The collision processing method provided by the embodiment of the present invention is described below by taking UE as an example.

The method and the device for processing conflict provided by the embodiment of the invention are described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.

Based on the communication system shown in fig. 1, an embodiment of the present invention provides a collision processing method, which is applied to a UE, and as shown in fig. 2, the collision processing method may include the following step 201.

Step 201, when the time domain resource of the first uplink transmission and the time domain resource of the second uplink transmission overlap, the UE processes the first uplink transmission and the second uplink transmission according to the uplink transmission information.

The uplink transmission information is information corresponding to the first uplink transmission and the second uplink transmission. The uplink transmission information may include any one of the following: channel access parameters; priority of uplink transmission and channel access parameters; the starting time domain position of the uplink transmission.

In the embodiment of the invention, the channel access parameters can comprise at least one of a channel access type and a channel access priority level.

Among them, the channel access type may include: type 2C channel access, type 2B channel access, type 2A channel access, type1channel access.

The channel access priority level may include: type1channel access with low channel access priority class (type 1channel access procedure with low channel access priority class) (e.g., channel access priority class p=1), type1channel access with high channel access priority class (type 1channel access procedure with high channel access priority class) (e.g., channel access priority class p=4).

Specifically, the priorities corresponding to the channel access parameters may include priorities of a channel access type and a channel access priority level, and the priorities are sequentially as follows from high to low: type 2C channel access, type 2B channel access, type 2A channel access, type 1 channel access with low channel access priority level, type 1 channel access with high channel access priority level.

Alternatively, the network device may configure or predefine the priority to which the channel access parameters correspond, e.g., configure or predefine the coarse-grained priority order: type 2C channel access, type 2B channel access, and type 2A channel access are high priority channel accesses, and type 1 channel access is a low priority channel access.

In the embodiment of the present invention, the priority of an uplink transmission, that is, the priority of the uplink transmission, may be the corresponding priority of the content carried by the uplink transmission, or may be the configured or indicated priority.

According to the conflict processing method provided by the embodiment of the invention, the UE can process the first uplink transmission and the second uplink transmission according to the uplink transmission information under the condition that the time domain resource of the first uplink transmission and the time domain resource of the second uplink transmission overlap. The uplink transmission information is information corresponding to the first uplink transmission and the second uplink transmission. Since the uplink transmission information may include any one of the following: channel access parameters; priority of uplink transmission and channel access parameters; the starting time domain position of the uplink transmission. Therefore, the UE can determine how to process the first uplink transmission and the second uplink transmission of the time domain resource conflict by combining the channel access parameter, or the priority of the uplink transmission and the channel access parameter, or the starting time domain position of the uplink transmission.

In the embodiment of the present invention, in the case where the uplink transmission information includes the channel access parameter, step 201 may be implemented by two possible implementations, a first possible implementation and a second possible implementation as follows. The uplink transmission information comprises the priority of uplink transmission and channel access parameters; step 201 may be implemented by a third possible implementation. The uplink transmission information comprises a starting time domain position of uplink transmission, and the transmission priority of the first uplink transmission is higher than that of the second uplink transmission; step 201 may be implemented by a fourth possible implementation as follows.

First possible implementation

Optionally, in the case where the uplink transmission information includes the channel access parameter, the step 201 may be performed by the following step 201a1 or step 201a 2:

in step 201a1, when the time domain resource of the first uplink transmission and the time domain resource of the second uplink transmission overlap, if the first priority is higher than the second priority, the UE transmits the first uplink transmission and discards the second uplink transmission.

The first priority is a priority corresponding to a channel access parameter of the first uplink transmission, and the second priority is a priority corresponding to a channel access parameter of the second uplink transmission.

In step 201a2, when the time domain resource of the first uplink transmission and the time domain resource of the second uplink transmission overlap, if the first priority is lower than or equal to the second priority, the UE multiplexes the first uplink transmission for transmission in the second uplink transmission.

It can be understood that in the embodiment of the present invention, the multiplexing the first uplink transmission in the second uplink transmission is multiplexing the information carried in the first uplink transmission in the second uplink transmission.

Specifically, if the first uplink transmission is a control channel, the UE may multiplex UCI carried in the first uplink transmission to be transmitted in the second uplink transmission.

Before transmitting uplink, the UE generally needs to detect the state of a channel, and if the channel is detected to be empty, it may perform access transmission, and if the channel is detected to be busy, it may not perform uplink. In step 202a, before the first uplink transmission is transmitted, a channel detection is further required for a channel corresponding to the first uplink transmission, and whether the UE can transmit the first uplink transmission is determined according to the channel detection result. In step 202a, after multiplexing the first uplink transmission into the second uplink transmission, channel detection is also required for the channel corresponding to the second uplink transmission, and it is determined whether the UE can transmit the second uplink transmission according to the channel detection result.

Example 1-1:

in combination with (a) in fig. 3, (b) in fig. 3, or (c) in fig. 3, the first uplink transmission is PUCCH, the second uplink transmission is PUSCH, and the time domain resource of PUCCH and the time domain resource of PUSCH overlap. The first priority is the priority corresponding to the channel access parameter of the PUCCH, and the second priority is the priority corresponding to the channel access parameter of the PUSCH. Taking the channel access parameter as the channel access type as an example, the PUCCH channel access type is the first access channel access type, and the PUSCH channel access type is the second channel access type. The first priority is the priority corresponding to the first channel access type of the PUCCH, the second priority is the priority corresponding to the second channel access type corresponding to the PUSCH, if the first priority is higher than the second priority, the UE transmits the PUCCH and discards the PUSCH, and if the first priority is lower than or equal to the second priority, the UE multiplexes the PUCCH into the PUSCH for transmission.

Alternatively, the first channel access type may be any one of the following: type 2C channel access, type 2B channel access, type 2A channel access, type 1 channel access with low level channel access priority level, type 1 channel access with high level channel access priority level. The second channel access type may be any one of the following: type 2C channel access, type 2B channel access, type 2A channel access, type 1 channel access with low channel access priority level, type 1 channel access with high channel access priority level.

In one possible implementation manner, if the UE determines that the channel access type corresponding to the PUCCH is type 2C channel access and the channel access type corresponding to the PUSCH is type 2A channel access, i.e. the first priority is higher than the second priority, the UE transmits the PUCCH and discards the PUSCH.

In another possible implementation manner, if the PUCCH corresponds to the channel access type is type 1 channel access and the PUSCH has the channel access type is type 2A channel access, i.e. the first priority is lower than the second priority, the UE multiplexes UCI carried by the PUCCH into the PUSCH for transmission.

In the embodiment of the present invention, if one uplink transmission is a PUCCH, the PUCCH may be a PUCCH carrying HARQ-ACK or CSI, and may be a PUCCH carrying SR.

Examples 1-2:

in combination with (a) in fig. 4, (b) in fig. 4, or (c) in fig. 4, the first uplink transmission is PUCCH 1, the second uplink transmission is PUCCH2, and time domain resources of PUCCH 1 and PUCCH2 overlap. The first priority is the priority corresponding to the channel access parameter of the PUCCH 1, the second priority is the priority corresponding to the channel access parameter of the PUCCH2, taking the channel access parameter as the channel access type as an example, the PUCCH 1 channel access type is the first access channel access type, and the channel access type of the PUCCH is the second channel access type. The first priority is the priority corresponding to the first channel access type of the PUCCH 1, the second priority is the priority corresponding to the second channel access type corresponding to the PUCCH2, if the first priority is higher than the second priority, the UE transmits the PUCCH 1 and discards the PUCCH2, and if the first priority is lower than or equal to the second priority, the UE multiplexes the PUCCH 1 into the PUCCH2 for transmission, or the UE transmits the PUCCH2 and discards the PUCCH 1.

In one possible implementation manner, if the channel access type corresponding to the PUCCH1 is type 2B channel access and the channel access type corresponding to the PUCCH 2 is type 1 channel access, that is, the first priority is higher than the second priority, the UE transmits the PUCCH1 and discards the PUCCH 2, or the UE multiplexes UCI carried by the PUCCH 2 onto the PUCCH1 for transmission.

In another possible implementation manner, if the type of channel access corresponding to PUCCH1 is type 1 channel access and the type of channel access of PUCCH 2 is type 2B channel access, that is, the first priority is lower than the second priority, the UE will transmit PUCCH 2, discard PUCCH1, or the UE multiplexes UCI carried by PUCCH1 into PUCCH 2 for transmission.

In this example 1-1 and example 1-2, the channel access parameters are exemplified as the channel access types. In practical applications, the channel access parameters of each uplink transmission in conflict may be channel access types, channel access priority levels, or part of channel access types, and part of channel access priority levels, which is not particularly limited in the embodiments of the present invention.

In this example, the UE may process according to the channel access parameters of each uplink transmission of the collision only, and may not limit the transmission priority of each uplink transmission of the collision, and may not limit the beginning symbol of each uplink transmission.

Based on the scheme, if time domain conflict exists in uplink transmission, the UE can determine how to process the time domain conflict, if the priority of the channel access parameter of one uplink transmission is higher than that of other uplink transmission, the UE can transmit the uplink transmission with the higher priority of the channel access parameter and discard the uplink transmission with the lower priority of the channel access parameter; if the priority of the channel access parameter of the other uplink transmission is equal to or lower than that of one uplink transmission, the UE may multiplex the other uplink transmission for transmission in the one uplink transmission.

Second possible implementation

Optionally, in the case where the uplink transmission information includes the channel access parameter, the step 201 may be performed by the following steps 201b1, 201b2, 201b3, or 201b 4:

in step 201b1, when the time domain resource of the first uplink transmission and the time domain resource of the second uplink transmission overlap, if the first channel access parameter is a specific channel access parameter and the second channel access parameter is a non-specific channel access parameter, the UE transmits the first uplink transmission and discards the second uplink transmission.

In step 201b2, when the time domain resource of the first uplink transmission and the time domain resource of the second uplink transmission overlap, if the first channel access parameter is a specific channel access parameter and the second channel access parameter is a non-specific channel access parameter, the UE multiplexes the second uplink transmission for transmission in the first uplink transmission.

The first channel access parameter is a channel access parameter of a first uplink transmission, and the second channel access parameter is a channel access parameter of a second uplink transmission.

Optionally, in the embodiment of the present invention, the specific channel access parameter may be a specific channel access type, or may be a specific channel access priority level.

Alternatively, the specific channel access parameters are predefined or configured by the network device through higher layer signaling.

By way of example, the specific channel access type may be a type 2C channel access or a type 2B channel access.

By way of example, a particular channel access priority class may have a type 1 channel access of a low channel access priority class.

For ease of illustration, the following examples are given by taking specific channel access parameters as specific channel access types.

In step 201b3, when the time domain resource of the first uplink transmission and the time domain resource of the second uplink transmission overlap, if the first channel access parameter and the second channel access parameter are both non-specific channel access parameters, the UE multiplexes the first uplink transmission and the second uplink transmission.

The above "multiplexing the first uplink transmission and the second uplink transmission" may be: multiplexing the first uplink transmission in the second uplink transmission, multiplexing the second uplink transmission in the first uplink transmission, or multiplexing the first uplink transmission and the second uplink transmission in the fourth uplink transmission.

In step 201b4, when the time domain resource of the first uplink transmission and the time domain resource of the second uplink transmission overlap, if the first channel access parameter is a non-specific channel access parameter, the UE multiplexes the first uplink transmission and the second uplink transmission.

Example 2-1:

combining (a) in fig. 3, (b) in fig. 3, or (c) in fig. 3, and the time domain resource of PUCCH and the time domain resource of PUSCH overlap.

In one implementation manner, the first uplink transmission is PUCCH, the second uplink transmission is PUSCH, the channel access parameter of the PUCCH is the first channel access parameter, and the channel access parameter of the PUSCH is the second channel access parameter. Taking the specific channel access parameter as the specific channel access type as an example, if the first channel access type corresponding to the PUCCH is type 2C channel access and the second channel access type corresponding to the PUSCH is non-type 2C channel access, namely the first channel access type is the specific channel access type and the second channel access type is the non-specific channel access type, the UE transmits the PUCCH and discards the PUSCH.

In another implementation manner, the first channel access type corresponding to the PUCCH is non-type 2C channel access, the second channel access type corresponding to the PUSCH is non-type 2C channel access, that is, the first channel access type and the second channel access type are both non-specific channel access types, and the UE multiplexes UCI carried by the PUCCH into the PUSCH for transmission.

In another implementation manner, the first uplink transmission is PUSCH, the second uplink transmission is PUCCH, the channel access parameter of the PUSCH is the first channel access parameter, and the channel access parameter of the PUCCH is the second channel access parameter. Taking the specific channel access parameter as the specific channel access type as an example, if the channel access type of the PUSCH is type 2C channel access and the first channel access type corresponding to the PUCCH is non-type 2C channel access, that is, the first channel access type is the specific channel access type and the second channel access type is the non-specific channel access type, the UE transmits the PUSCH and discards the PUCCH, or multiplexes the PUCCH into the PUSCH for transmission.

In general, if time domain resources of one PUCCH and PUSCH (at least one) overlap. The PUCCH and PUSCH may have the same priority, different priorities, and no priority indication. According to the related art, the UE multiplexes UCI carried by PUCCH for transmission on PUSCH, and performs channel access before the PUSCH transmission. If the PUCCH and the PUSCH are in different RBs set (or serving cell), the UE may need to perform different types of channel access when transmitting the PUCCH or the PUSCH, for example, the PUCCH is in a base station shared COT (gNB's shared COT), then only type 2C channel access needs to be performed before PUCCH transmission, i.e. no channel detection needs to be performed, and the PUSCH is Configured grant PUSCH (CG PUSCH), and type 1 channel access needs to be performed before transmission. That is, if PUCCH and PUSCH multiplexing is not performed, PUCCH channel access must be successful (since LBT is not required to be performed, the UE may directly transmit PUCCH), whereas if PUCCH is transmitted to the multiplexed PUSCH, transmission may not be possible due to channel detection being required (in case that the corresponding channel is detected as busy).

If the conflict processing mode provided by the embodiment of the invention is adopted, the UE can determine whether to multiplex the PUCCH on the PUSCH according to the channel access parameters respectively corresponding to the PUCCH and the PUSCH, and the UE directly transmits the PUCCH under the condition that the channel access type corresponding to the PUCCH is a specific channel access type, so that the UCI transmission possibility borne on the PUCCH is improved.

Example 2-2:

in combination with (a) in fig. 4, (b) in fig. 4, or (c) in fig. 4, the first uplink transmission is PUCCH 2, the second uplink transmission is PUCCH 2, the channel access parameter corresponding to PUCCH 1 is the first channel access parameter, the channel access parameter corresponding to PUCCH 2 is the second channel access parameter, and the PUCCH 1 and PUCCH 2 time domain resources overlap. Taking the specific channel access parameter as an example of the specific channel access type, it is assumed that the specific channel access is a type 2C channel access.

In one implementation, if the UE determines that the first channel access type corresponding to PUCCH 1 is type 2C channel access and the second channel access type corresponding to PUCCH 2 is non-type 2C channel access, i.e. the first channel access type is specific channel access and the second channel access type is non-specific channel access, the UE may transmit PUCCH 1, discard PUCCH 2, or multiplex PUCCH 2 for transmission in PUCCH 1.

In another implementation manner, if the UE determines that the first channel access type corresponding to the PUCCH1 and the second channel access type corresponding to the PUCCH2 are both non-type 2C channel accesses, that is, are both non-specific channel accesses, or if the UE determines that the first channel access type corresponding to the PUCCH1 or the second channel access type corresponding to the PUCCH2 is non-type 2C channel accesses, that is, the UE determines that one of the channel access types corresponding to the PUCCH is non-specific channel accesses, the UE may multiplex UCI carried on the PUCCH1 onto PUCCH2, or the UE may multiplex UCI carried on PUCCH2 onto PUCCH1, or may multiplex UCI carried on PUCCH1 and PUCCH2 onto one PUCCH.

In general, a primary serving cell (Pcell) of a primary serving cell/primary cell group contains multiple RBs sets, each PUCCH indicating which one of the RBs sets it is located in when configured. There will be HARQ-ACK PUCCH (i.e. PUCCH for carrying HARQ-ACK) and SR PUCCH (i.e. PUCCH for carrying SR) within different RB sets. For example, the HARQ-ACK PUCCH and the DCI corresponding to the HARQ-ACK PUCCH belong to the same RB set, and only type 2C channel access needs to be performed within the COT shared by the base stations. The SR PUCCH needs to perform type 1 channel access in another RB set. According to the related art, if the PUCCH formats of the HARQ-ACK PUCCH and the SR PUCCH are both PUCCH format 1, the UE needs to multiplex the HARQ-ACK on the SR PUCCH for transmission, and the SR PUCCH needs to perform type 1 channel access, if the channel is detected as busy, the UE may not transmit the SR PUCCH, i.e. the HARQ-ACK, so that the probability of HARQ-ACK transmission is reduced in the related art.

If the conflict processing mode provided by the embodiment of the invention is adopted, the UE can determine whether to multiplex the SR PUCCH and the HARQ-ACK PUCCH according to the channel access parameter of the HARQ-ACK PUCCH and the channel access parameter of the SR PUCCH. If the UE discards the SR, the HARQ-ACK PUCCH is transmitted, and in case that the channel access of the HARQ-ACK PUCCH belongs to type 2C, the UE does not need to perform channel detection, thereby increasing the possibility that the UE transmits the HARQ-ACK.

It should be noted that the above scheme may also be applied to a scenario in which time domain resources of SR PUCCH and CSI PUCCH collide, or to a scenario in which time domain resources of HARQ-ACK PUCCH and CSI PUCCH collide.

In this example 2-1 and example 2-2, the channel access parameters are exemplified as specific channel access types. In practical applications, the channel access parameters of each uplink transmission in conflict may be channel access types, channel access priority levels, or part of channel access types, and part of channel access priority levels, which is not particularly limited in the embodiments of the present invention.

In this example, the UE may process only according to whether the channel access parameter of each uplink transmission in the collision is a specific channel access parameter, and may not limit the transmission priority of each uplink transmission in the collision or the beginning and ending of each uplink transmission (for example, (a) in fig. 3, (b) in fig. 3, and (c) in fig. 3, and the above-described processing manner may be adopted for the scenes corresponding to (a) in fig. 4, (b) in fig. 4, and (c) in fig. 4).

Based on the scheme, under the circumstance that time domain resources collide, the UE can determine how to process each uplink transmission according to the channel access parameters of each time domain resource in the collision, specifically, if one uplink transmission has a channel access parameter of a specific channel access parameter, the UE can transmit the uplink transmission, discard uplink transmissions with other channel access parameters of non-specific channel access parameters, and if two uplink transmissions in the collision do not have a channel access parameter of an uplink transmission of a specific channel access parameter, the UE can multiplex one of the uplink transmissions for transmission in the other uplink transmission.

It should be noted that, in the first possible implementation manner, the UE may not consider the transmission priority of the uplink in the second possible implementation manner, that is, in a case where the transmission priority of the first uplink is higher than the transmission priority of the second uplink, in a case where the transmission priority of the first uplink is lower than the transmission priority of the second uplink, in a case where the first uplink and the second uplink have the same transmission priority, or in a case where no transmission priority indication is available, both the above two possible implementation manners may be adopted. In a third possible implementation manner described below, the UE may determine how to handle the time domain collision between uplink transmissions in combination with the transmission priorities of the respective uplink transmissions.

Third possible implementation

Optionally, in the case where the uplink transmission information includes the priority of uplink transmission and the channel access parameter, the step 201 may be performed by the following step 201c1 or step 201c 2:

in step 201c1, when the time domain resource of the first uplink transmission and the time domain resource of the second uplink transmission overlap, if the third priority is higher than or equal to the fourth priority and the first condition is satisfied, the UE multiplexes the first uplink transmission for transmission in the second uplink transmission.

In step 201c2, when the time domain resource of the first uplink transmission and the time domain resource of the second uplink transmission overlap, if the third priority is higher than or equal to the fourth priority and the first condition is not satisfied, the UE transmits the first uplink transmission and discards the second uplink transmission.

The third priority is a transmission priority of the first uplink transmission, and the fourth priority is a transmission priority of the second uplink transmission.

In the embodiment of the present invention, the first condition is that the channel access parameter of the second uplink transmission is a specific channel access parameter, or that the priority corresponding to the channel access parameter of the second uplink transmission is higher than the priority corresponding to the channel access parameter of the first uplink transmission.

For simplicity of description, in uplink transmission where there will be time domain resource overlap in the following examples, PUSCH with a high transmission priority is referred to as high PUSCH, and is denoted as PUSCH H in the drawing; the PUSCH with low transmission priority is referred to as low PUSCH, and is denoted as PUSCH L in the drawing; the PUCCH with a high transmission priority is referred to as a high PUCCH, and is denoted as PUCCH H in the drawing; the PUCCH with low transmission priority is referred to as a low PUCCH, and is denoted as PUCCH L in the drawing.

Example 3-1:

in combination with (a) in fig. 5, (b) in fig. 5, or (c) in fig. 5, the first uplink transmission is PUCCH, the second uplink transmission is PUSCH, and PUCCH is high PUCCH, PUSCH is low PUSCH, and high PUCCH and low PUSCH time domain resources overlap.

In one mode, when the first condition is that the channel access parameter of the second uplink transmission is a specific channel access parameter, taking the specific channel access parameter as an example of a specific channel access type, if the channel access type corresponding to the low PUSCH is type 2C channel access and the channel access type of the high PUCCH is non-type 2C channel access, the UE multiplexes UCI carried by the high PUCCH for transmission in the low PUSCH.

In another manner, when the first condition is that the priority corresponding to the channel access parameter of the second uplink transmission is higher than the priority corresponding to the channel access parameter of the first uplink transmission, taking the specific channel access parameter as the specific channel access type as an example, if the channel access type corresponding to the low PUSCH is the first channel access type, the channel access type of the high PUCCH is the second channel access type, and the priority corresponding to the channel access type corresponding to the low PUSCH is higher than the priority corresponding to the channel access type of the high PUCCH, the UE multiplexes UCI carried by the high PUCCH in the low PUSCH for transmission.

In another manner, if the UE determines that the first condition is not satisfied, for example, if the channel access type corresponding to the low PUSCH is a non-type 2C channel access, i.e., the channel access type corresponding to the low PUCSH is a non-specific channel access type, the UE will transmit the high PUCCH and discard the low PUSCH.

In another manner, when the first condition is that the priority corresponding to the channel access parameter of the second uplink transmission is higher than the priority corresponding to the channel access parameter of the first uplink transmission, taking the specific channel access parameter as the specific channel access type as an example, if the channel access type corresponding to the low PUSCH is the first channel access type, the channel access type of the high PUCCH is the second channel access type, and the priority corresponding to the channel access type corresponding to the low PUSCH is lower than the priority corresponding to the channel access type of the high PUCCH, the UE will transmit the high PUCCH, and discard the low PUSCH.

It should be noted that, in the first possible implementation manner, in the second possible implementation manner and in the third possible implementation manner, the UE may not consider the sequence relationship of the starting time domain positions between the uplink transmissions, that is, may use the above three possible implementation manners to process when the starting time domain positions of the uplink transmissions are the same or different. In a fourth possible implementation manner described below, the UE may determine how to handle the time domain collision between uplink transmissions in combination with the sequence of the starting time domain positions between the uplink transmissions.

Fourth possible implementation

Optionally, in the collision processing method provided in the embodiment of the present invention, when the uplink transmission information includes a starting time domain position of the uplink transmission, and the transmission priority of the first uplink transmission is higher than the transmission priority of the second uplink transmission, the step 201 may be performed by the following step 201d1 or step 201d 2:

in step 201d1, if the UE overlaps the time domain resource of the first uplink transmission and the time domain resource of the second uplink transmission, the second uplink transmission is discarded if the second starting time domain position is earlier than the first starting time domain position.

The first initial time domain position is the initial time domain position of the first uplink transmission, and the second initial time domain position is the initial time domain position of the second uplink transmission.

In step 201d2, when the time domain resource of the first uplink transmission and the time domain resource of the second uplink transmission overlap, if the second starting time domain position is later than or equal to the first starting time domain position, the UE processes the first uplink transmission and the second uplink transmission according to the channel detection result corresponding to the first uplink transmission.

Wherein the channel detection result includes that the channel is empty or the channel is busy.

Optionally, if the second starting time domain position is equal to the first starting time domain position, the first uplink transmission and the second uplink transmission correspond to different resource block sets.

In the embodiment of the present invention, in step 201d2 described above, the UE may determine whether to transmit only the uplink transmission with high transmission priority or multiplex the content (for example, UCI) carried on the uplink transmission with high transmission priority on part or all of the uplink transmissions with low transmission priority according to the channel detection result corresponding to the uplink transmission with high transmission priority. That is, the UE may prepare to transmit uplink with high transmission priority, and at the same time, the UE may prepare that a channel corresponding to the uplink with high transmission priority is busy, and the UE may multiplex the content carried on the uplink with high transmission priority onto one of the uplink with low transmission priority according to a multiplexing rule, and may also multiplex the content carried on the uplink with high transmission priority onto a plurality of or all of the uplink with low transmission priority.

Before transmitting the uplink transmission with high transmission priority, the UE performs channel access, if the channel corresponding to the uplink transmission with high transmission priority is detected to be empty, the UE transmits the uplink transmission with high transmission priority, if the channel corresponding to the uplink transmission with high transmission priority is detected to be busy, the UE detects the channel corresponding to the multiplexed uplink transmission with low transmission priority, if the channel detected to be empty, the uplink transmission with low transmission priority and the content carried on the uplink transmission with high transmission priority are transmitted, and if any other uplink transmission with low transmission priority is not multiplexed, the UE determines whether to transmit according to the respective channel access result.

Before transmitting the uplink transmission with high transmission priority, the UE performs channel access, if the channel corresponding to the uplink transmission with high transmission priority is detected to be empty, the UE transmits the uplink transmission with high transmission priority, if the channel corresponding to the uplink transmission with high transmission priority is detected to be busy, the UE can determine whether to transmit according to the channel access result (the channel needs to be detected and is busy or empty, the channel does not need to be detected) corresponding to the uplink transmission with low transmission priority, and if the channel access is successful, the uplink transmission with low transmission priority and the content carried on the uplink transmission with high transmission priority are transmitted.

In the embodiment of the present invention, in the fourth possible implementation manner, the step 201d2 may be performed by the following step 201e1, step 201e2 or step 201e 3:

in step 201e1, when the time domain resource of the first uplink transmission and the time domain resource of the second uplink transmission overlap, if the second starting time domain position is later than or equal to the first starting time domain position, the UE transmits the first uplink transmission and discards the second uplink transmission if the channel corresponding to the first uplink transmission is null.

In step 201e2, when the time domain resource of the first uplink transmission and the time domain resource of the second uplink transmission overlap, if the second starting time domain position is later than or equal to the first starting time domain position, the UE multiplexes the first uplink transmission for transmission in the second uplink transmission if the channel corresponding to the first uplink transmission is busy.

In step 201e3, when the time domain resource of the first uplink transmission and the time domain resource of the second uplink transmission overlap, if the second starting time domain position is later than or equal to the first starting time domain position, if the channel corresponding to the first uplink transmission is busy, the UE transmits the second uplink transmission, and discards the first uplink transmission.

Based on this scheme, in the conflict processing method provided by the embodiment of the present invention, if the time domain resources of the high transmission priority uplink (the first uplink transmission) and the low transmission priority uplink (the second uplink transmission) overlap, when the starting time domain position of the low transmission priority uplink is later than or equal to the starting time domain position of the high transmission priority, and the channel corresponding to the high transmission priority uplink is busy, the UE may multiplex the high transmission priority uplink in the low priority uplink, or transmit the low transmission priority uplink and discard the high priority uplink, compared with the mode that the UE only transmits the low transmission priority uplink according to the uplink in the related art, the possibility of transmitting the low transmission priority uplink is increased.

In the embodiment of the present invention, if an uplink transmission with a high priority is the same as the starting time domain position of one or more low transmission priorities, the UE may first detect whether a channel corresponding to the uplink transmission with the high transmission priority is empty. If the channel corresponding to the uplink transmission with high transmission priority is detected to be empty, whether the channel corresponding to the uplink transmission with low transmission priority is empty is not concerned. If the channel corresponding to the uplink transmission with the high transmission priority is detected to be busy, determining how to process each uplink transmission according to whether the channel corresponding to the uplink transmission with the one or more low transmission priorities is empty.

In an embodiment of the present invention, in a fourth possible implementation manner, the uplink transmission information includes a starting time domain position of uplink transmission, the second uplink transmission includes fourth uplink transmission and fifth uplink transmission, and a priority of the first uplink transmission is higher than a priority of the fourth uplink transmission and a priority of the fifth uplink transmission; the above step 201 may be performed by the following step 201d 3:

step 201d3, if the first starting time domain position is earlier than the third starting time domain position and later than the fourth starting time domain position, discarding the fourth uplink transmission, and processing the first uplink transmission and the fifth uplink transmission according to the channel detection result corresponding to the first uplink transmission.

The first initial time domain position is the initial time domain position of the first uplink transmission, the third initial time domain position is the initial time domain position of the fourth uplink transmission, and the fourth initial time domain position is the initial time domain position of the fifth uplink transmission.

It should be noted that, the step 201d3 may be specifically determined by the step 201d1 and the step 201d 2.

It may be appreciated that, in combination with step 201d1 and step 201d2, when the second uplink transmission includes a plurality of uplink transmissions, the UE may discard uplink transmissions having a starting time domain position earlier than a starting time domain position of the first uplink transmission in the plurality of uplink transmissions included in the second uplink transmission, and then, according to a channel detection result of the first uplink transmission, determine that the starting time domain position in the plurality of uplink transmissions included in the first uplink transmission and the second uplink transmission is not earlier than the starting time domain position of the first uplink transmission.

Optionally, in the method for collision processing provided in the embodiment of the present invention, in the fourth possible implementation manner, the "multiplexing the first uplink transmission for transmission in the second uplink transmission" in step 201e2 may be performed by the following steps 301 to 303:

step 301, the UE multiplexes the first uplink transmission in the second uplink transmission.

Step 302, the UE detects a state of a channel corresponding to the second uplink transmission.

Step 303, if the channel corresponding to the second uplink transmission is null, the UE multiplexes the second uplink transmission after the first uplink transmission.

It can be understood that if the UE multiplexes the first uplink transmission in the second uplink transmission, and then performs channel access on the second uplink transmission after multiplexing the first uplink transmission, and if the channel access process detects that the channel is empty or the channel does not need to be detected, the UE multiplexes the second uplink transmission after multiplexing the first uplink transmission. If the channel is detected to be busy, the UE does not transmit the second uplink transmission after multiplexing the first uplink transmission.

Alternatively, in the fourth possible implementation manner, step 201e2 may be specifically performed by the following step 201f1 or step 201f 2:

in step 201f1, when the time domain resource of the first uplink transmission and the time domain resource of the second uplink transmission overlap, if the second starting time domain position is later than or equal to the first starting time domain position, the channel corresponding to the first uplink transmission is busy, and the interval between the second starting time domain position and the first starting time domain position is greater than or equal to the first threshold, the first uplink transmission is multiplexed for transmission in the second uplink transmission.

In step 201f2, if the UE overlaps the time domain resource of the first uplink transmission and the time domain resource of the second uplink transmission, and if the second starting time domain position is later than or equal to the first starting time domain position, the channel corresponding to the first uplink transmission is busy and the interval between the second starting time domain position and the first starting time domain position is less than the first threshold, the first uplink transmission and the second uplink transmission are discarded.

Namely, in the scheme, under the condition that the time domain resource of the first uplink transmission and the time domain resource of the second uplink transmission overlap, if the second initial time domain position is earlier than or equal to the first initial time domain position, or the second initial time domain position is later than the first initial time domain position but the interval between the second initial time domain position and the first initial time domain position is smaller than a first threshold value, the UE discards the second uplink transmission; if the second initial time domain position is later than the first initial time domain position and the interval between the second initial time domain position and the first initial time domain position is not smaller than the first threshold, the UE determines whether to multiplex the first uplink transmission content on the second uplink transmission according to the channel detection result of the second uplink transmission.

Alternatively, in the fourth possible implementation manner, step 201e2 may be specifically performed by the following step 201g1 or step 201g 2:

In step 201g1, when the time domain resource of the first uplink transmission and the time domain resource of the second uplink transmission overlap, if the second starting time domain position is later than or equal to the first starting time domain position, the channel corresponding to the first uplink transmission is busy, and if the interval between the second starting time domain position and the first starting time domain position is greater than or equal to the second threshold, the second uplink transmission is transmitted, and the first uplink transmission is discarded.

In step 201g2, when the time domain resource of the first uplink transmission and the time domain resource of the second uplink transmission overlap, if the second starting time domain position is later than or equal to the first starting time domain position, the channel corresponding to the first uplink transmission is busy, and if the interval between the second starting time domain position and the first starting time domain position is less than the second threshold, the first uplink transmission and the second uplink transmission are discarded.

Namely, in the scheme, under the condition that the time domain resource of the first uplink transmission and the time domain resource of the second uplink transmission overlap, if the second initial time domain position is earlier than or equal to the first initial time domain position, or the second initial time domain position is later than the first initial time domain position but the interval between the second initial time domain position and the first initial time domain position is smaller than a second threshold value, the UE discards the second uplink transmission; if the second initial time domain position is later than the first initial time domain position and the interval between the second initial time domain position and the first initial time domain position is not smaller than the first threshold, the UE determines whether to perform the second uplink transmission according to the channel detection result of the second uplink transmission.

In order to facilitate understanding of the fourth possible implementation manner of the embodiment of the present invention, the following description illustrates that the starting time domain position of the uplink transmission with high transmission priority is the same as or different from the starting time domain position of the uplink transmission with low transmission priority. Wherein examples 4-1 to 4-3 are examples in which the starting time domain positions of the uplink transmissions of the time domain resources overlap are the same, and examples 4-4 to 4-7 are examples in which the starting time domain positions of the time domain resources of the uplink transmissions of the high transmission priority are different from the starting time domain positions of the uplink transmissions of the low transmission priority.

For simplicity of description, in the following examples 4-1 to 4-6, for each uplink transmission with overlapping time domain resources, PUSCH with high transmission priority is still referred to as high PUSCH, PUSCH with low transmission priority is referred to as low PUSCH, PUCCH with high transmission priority is referred to as high PUCCH, and PUCCH with low transmission priority is referred to as low PUCCH, which will not be described in detail.

Example 4-1: high PUSCH-Low PUCCH

Referring to fig. 5 (a), the first uplink transmission is PUSCH, the second uplink transmission is PUCCH, the first starting time domain position is a starting time domain position of PUSCH, the second starting time domain position is a PUCCH starting time domain position, PUSCH is high PUSCH, PUCCH is low PUCCH, a time domain resource of high PUSCH overlaps a time domain resource of low PUCCH, and the starting time domain position of high PUSCH is the same as the starting time domain position of low PUCCH, i.e., the first starting time domain position and the second starting time domain position are the same. Wherein the high PUSCH and the low PUCCH are located in different RB sets (or serving cells).

If the UE detects that the channel in the RB set where the high PUSCH is located is empty, the UE does not pay attention to the channel detection result in the RB set where the low PUCCH is located any more, and the processing is performed in the following manner a1 or a 2.

Mode a1: the UE transmits the high PUSCH and discards the low PUCCH.

Mode a2: the UE multiplexes UCI carried on the low PUCCH for transmission on the high PUSCH.

When the high PUSCH includes a plurality of high PUSCHs (each located in a different serving cell), if the UE detects that the channel in the RB set where any one of the high PUSCHs is located is empty, the UE discards the low PUCCH.

If the UE detects that the channel in the RB set corresponding to the high PUSCH is busy, the UE performs processing according to the following method a3 or method a4 based on the channel detection result in the RB set where the low PUCCH is located.

Mode a3: if the UE detects that the channel in the RB set where the low PUCCH is located is empty, the UE transmits the low PUCCH and UCI carried by the low PUCCH, and discards the high PUSCH.

Mode a4: if the UE detects that the channel in the RB set where the low PUCCH is located is busy, the UE discards the high PUSCH and the low PUCCH.

In the related art, in the scenario corresponding to example 4-1, the UE cancels the low PUCCH transmission and performs channel access before the high PUSCH transmission, if the UE detects that the channel corresponding to the high PUSCH is busy, the UE does not transmit the high PUSCH, and the UE does not transmit the high PUSCH or the low PUCCH, so the transmission performance is not high.

According to the processing manner in the above example 4-1 in the embodiment of the present invention, the UE may perform processing based on the channel detection result of the high PUSCH and the channel detection result of the low PUCCH, so as to increase the possibility of uplink transmission, and improve the transmission performance of the UE.

Example 4-2: high PUCCH 1-Low PUCCH 2

Referring to fig. 6, the first uplink transmission is PUCCH 1, the second uplink transmission is PUCCH 2, the starting time domain position of PUCCH 1 is the first starting time domain position, the starting time domain position of PUCCH 2 is the second starting time domain position, PUCCH 1 is high PUCCH 1, PUCCH 2 is low PUCCH 2, the time domain resource of high PUCCH 1 overlaps with the time domain resource of low PUCCH 2, and the starting time domain position of high PUCCH 1 is the same as the starting time domain position of low PUCCH 2, i.e. the first starting time domain position is the same as the second starting time domain position. Wherein the high PUCCH 1 and the low PUCCH 2 are located at different RB sets (or serving cells).

If the UE detects that the channel in the RB set where the high PUCCH 1 is located is empty, the UE does not pay attention to the channel detection result in the RB set where the low PUCCH 2 is located any more, and may process the channel detection result in the following manner b1 or manner b 2.

Mode b1: the UE transmits high PUCCH 1 and discards low PUCCH 2.

Mode b2: the UE multiplexes UCI carried by the low PUCCH 2 for transmission on the transmission high PUCCH 1.

If the UE detects that the channel in the RB set corresponding to the high PUCCH 1 is busy, the UE may perform the following methods b3, b4, b5, or processing according to the channel detection result in the RB set in which the low PUCCH 2 is located.

Mode b3: if the UE detects that the channel in the RB set where the low PUCCH 2 is located is empty, the UE transmits the low PUCCH 2 and discards the high PUCCH 1.

Mode b4: if the UE detects that the channel in the RB set where the low PUCCH 2 is located is null, the UE multiplexes UCI in the high PUCCH 1 for transmission on the low PUCCH 2.

Mode b5: if the UE detects that the channel in the RB set where the low PUCCH 2 is located is busy, the UE discards the high PUCCH 1 and the low PUCCH 2.

In the related art, in the scenario corresponding to example 4-2, the UE may cancel transmitting the low PUCCH 1 and perform channel access before transmitting the high PUCCH 2, and if the channel in the RB set where the high PUCCH 2 is detected to be busy, the UE does not transmit the high PUCCH 2, i.e. the UE does not transmit the high PUCCH 1 nor the low PUCCH 2, and the transmission performance is not high.

According to the processing manner in the above example 4-2 in the embodiment of the present invention, the UE may perform processing based on the channel detection result of the high PUCCH and the channel detection result of the low PUCCH, so as to increase the possibility of uplink transmission, and improve the transmission performance of the UE.

The starting time domain positions of uplink transmissions where the time domain resources of examples 4-4 to 4-6 described below overlap are different.

Examples 4-4: high PUCCH-Low PUSCH (one or more Low PUSCHs)

Referring to fig. 8, the first uplink transmission is a PUCCH, the second uplink transmission includes at least one PUSCH, the PUCCH is a high PUSCH, the at least one PUSCH is a low PUSCH, and one high PUCCH overlaps with a plurality of low PUSCH time domain resources. The starting time domain position of the high PUCCH is different from the starting time domain positions of the plurality of low PUSCHs (wherein the starting time domain positions of the plurality of low PUSCHs may be the same or different). According to the sequence of the initial time domain positions of each uplink transmission, the method can be specifically divided into the following

scenes

1, 2 and 3.

Scene 1: as in (a) of fig. 8, the first starting time domain position of the high PUCCH is earlier than the starting time domain positions of all low PUSCHs (including low PUSCH 1 and low PUSCH 2 shown in (a) of fig. 8), i.e. the first starting time domain position is earlier than the third starting time domain position and the first starting time domain position is earlier than the fourth starting time domain position.

First, the UE detects a channel in the RB set where the high PUCCH is located (performs channel access), and if the channel in the RB set where the high PUCCH is located is null, the UE does not pay attention to the channel detection results in the RB set where all the low PUSCHs are located. The UE may process in the following manner d 1.

Mode d1: the UE transmits the high PUCCH and discards all low PUSCHs.

Then, if the UE detects that the intra-RB set channel corresponding to the high PUCCH is busy, the UE may process in the following manner d2, manner d3, or manner d 4.

Mode d2: the UE discards the high PUCCH and transmits each low PUSCH (low PUSCH 1 and low PUSCH 2) separately.

It can be understood that, before transmitting each low PUSCH, the UE performs channel access, detects that the corresponding channel is empty, transmits PUSCH, detects that the corresponding channel is busy, and cancels the transmission of PUSCH.

Mode d3: the UE multiplexes the high PUCCH for transmission in one of the low PUSCHs.

The low PUSCH is selected by the UE according to the 1 st multiplexing priority rule and the 2 nd multiplexing priority rule provided in the following embodiments of the present invention, or may be selected by the first multiplexing priority rule in the related art, or may be selected by the UE randomly.

Mode d4: the UE multiplexes the high PUCCH for transmission in all low PUSCHs.

Scene 2: as in (c) of fig. 8, the starting time domain positions of all low PUSCHs (low PUSCH 1 and low PUSCH 2) are earlier than the starting time domain position of the high PUCCH, the UE may process as d5 described below.

Mode d5: the UE cancels all low PUSCH 1 and low PUSCH 2, and transmits high PUCCH.

Scene 3: as in (b) of fig. 8, the starting time domain position of at least one low PUSCH (low PUSCH 1) is earlier than the starting time domain position of the high PUCCH, and the starting time domain position of at least one low PUSCH (low PUSCH 2) is not earlier than the starting time domain position of the high PUCCH.

First, the UE discards all low PUSCHs (low PUSCH 1) having a starting time domain position earlier than that of the high PUCCH, among the plurality of low PUSCHs.

Then, the UE detects a channel in the RB set where the high PUCCH is located, and if the channel in the RB set where the high PUCCH is located is busy, the UE can process the channel in the following manner d6, manner d7, or manner d 8.

Mode d6: the UE discards the high PUCCH and sequentially transmits all low PUSCHs (low PUSCH 2) later than the starting time domain position of the high PUCCH.

Mode d7: the UE multiplexes the high PUCCH for transmission in one low PUSCH (low PUSCH 2) at a starting time domain position not earlier than the starting time domain position of the high PUCCH.

Mode d8: the UE multiplexes the high PUCCH for transmission in all low PUSCHs having a starting time domain position not earlier than the starting time domain position of the high PUCCH.

Examples 4-5: multiple high PUSCH-Low PUCCH

Referring to fig. 9, the first uplink transmission includes a plurality of PUSCHs, the second uplink transmission is a PUCCH, the plurality of PUSCHs is a high PUSCH, the PUCCH is a low PUCCH, and the plurality of high PUSCHs overlap with one low PUCCH time domain resource. The starting time domain position of the high PUSCH is different from the starting time domain position of the low PUCCH (wherein the starting time domain positions of the plurality of high PUSCHs may be the same or different). The multiple high PUSCHs and one low PUCCH may be located in the same RB set (or serving cell) or may be located in different RB sets (or serving cells). The UE may process in the following manner e1, manner e2, or manner e 3:

mode e1: as shown in fig. 9 (a), taking the starting time domain position as an example of the starting symbol, if the starting symbol of the low PUCCH is earliest, the UE discards the low PUCCH and sequentially transmits a plurality of high PUSCHs.

In mode e2, as shown in fig. 9 (c), if the start symbol of the low PUCCH is the latest, the UE transmits a plurality of high PUSCH and low PUCCH, respectively. The UE processes the PUCCH and each PUSCH according to the channel detection result corresponding to each PUSCH, discards the PUCCH if detecting that the channel where any PUSCH is located is empty, determines whether to transmit the PUCCH according to the channel detection result corresponding to the PUCCH if detecting that each PUSCH is busy, discards the PUCCH if the channel corresponding to the PUCCH is busy, and transmits the PUCCH if the channel corresponding to the PUCCH is empty.

Mode e3 as in (b) of fig. 9, if the start symbol of the low PUCCH is later than the start symbol of at least one high PUSCH and earlier than the start symbol of at least one high PUSCH, the UE discards the low PUCCH and transmits the plurality of high PUSCHs, respectively. The transmission of the plurality of high PUSCHs may be handled in the manner of reference e2, which is not described herein.

Examples 4-6: high PUCCH 1-Low PUCCH 2

Referring to fig. 10, the first uplink transmission is PUCCH1, the second uplink transmission is PUCCH 2, PUCCH1 is high PUCCH1, PUCCH 2 is low PUCCH 2, the starting time domain position of PUCCH1 is the first starting time domain position, the starting time domain position of PUCCH 2 is the second starting time domain position, and the high PUCCH1 time domain resource and the low PUCCH 2 time domain resource overlap. The high PUCCH1 and the low PUCCH 2 may be located in the same RB set (or serving cell), or may be located in different RB sets (or serving cells).

(1) As in (b) of fig. 10, the first starting time domain position of the high PUCCH1 is earlier than the second starting time domain position of the low PUCCH 2.

The UE first detects the channel in the RB set where the high PUCCH1 is located, and if the channel in the RB set where the high PUCCH1 is located is null, the UE transmits the high PUCCH1 and discards the low PUCCH 2. If the channel in the RB set where the high PUCCH1 is located is busy, the UE discards the high PUCCH1, detects the channel in the RB set where the low PUCCH 2 is located, and if the channel in the RB set where the low PUCCH 2 is located is empty, discards the high PUCCH1, and transmits the low PUCCH 2.

(2) As in (a) and (c) of fig. 10, if the first starting time domain position of the high PUCCH 1 is later than or equal to the second starting time domain position of the low PUCCH2, the UE discards the low PUCCH2. Further, if the channel in the RB set where the high PUCCH 1 is located is null, the high PUCCH 1 is transmitted.

(3) As shown in fig. 10 (a), if the first starting time domain position of the high PUCCH 1 is equal to the second starting time domain position of the low PUCCH2, and if the RB set of the high PUCCH 1 is different from the RB set of the low PUCCH2, the processing manner of the high PUCCH 1 and the low PUCCH2 is determined according to the detection result of the channel in the RB set of the high PUCCH 1. Specifically, the UE detects a channel in the RB set where the high PUCCH 1 is located, and if the channel in the RB set where the high PUCCH 1 is located is null, the UE transmits the high PUCCH 1 and discards the low PUCCH2. If the channel in the RB set where the high PUCCH 1 is located is busy, the UE discards the high PUCCH 1, and if the channel in the RB set where the low PUCCH2 is detected to be empty, discards the high PUCCH 1, and transmits the low PUCCH2.

Examples 4-7: high PUSCH-Low PUCCH (at least two)

Referring to fig. 11, the first uplink transmission is PUSCH, the second uplink transmission includes at least one PUCCH, the PUSCH is high PUSCH, the PUCCH is low PUCCH, and the high PUSCH time domain resource overlaps with the plurality of low PUCCH time domain resources. The high PUSCH and the plurality of low PUCCHs may be located in the same RB set (or serving cell), or may be located in different RB sets (or serving cells).

Scene a: as in (a) of fig. 11, the high PUSCH is the same as the earlier low PUCCH1 starting symbol.

If the low PUCCH1 having the earlier starting symbol in the high PUSCH and the low PUCCH is in different RB set, the UE detects the channel in the RB set in which the high PUSCH is located, and detects the channel in the RB set in which the low PUCCH1 is located.

(1) If the channel in the RB set where the high PUSCH is located is empty, the UE transmits the high PUSCH and discards all the low PUCCH.

(2) If the channel in the RB set where the high PUSCH is located is busy and the channel in the RB set where the low PUCCH1 is located is empty, the UE transmits the low PUCCH1 and discards the high PUSCH. The UE performs corresponding channel access before transmitting the low PUCCH 2, and if a channel null is detected, transmits the PUCCH 2.

(3) If the channel in the RB set where the high PUSCH is located is busy and the channel in the RB set where the low PUUCH 1 is located is busy, the UE discards the high PUSCH and the low PUCCH 1. Before transmitting the low PUCCH 2, the UE performs corresponding channel access and processes according to a channel detection result in the RB set of the low PUCCH 2, if the channel is detected to be empty, the PUCCH 2 is transmitted, otherwise, the PUCCH 2 is not transmitted.

If the low PUCCH1 with the earlier starting symbol in the high PUSCH and the low PUCCH is in the same RB set, the UE transmits the high PUSCH and discards the low PUCCH1 and the low PUCCH 2 if the channel in the RB set is empty. If the channel in the RB set is busy, the low PUCCH1 and the high PUSCH are discarded. The UE transmits the low PUCCH 2 according to the channel detection result within the RB set of the low PUCCH 2 before transmitting the low PUCCH 2.

Scene b: as shown in fig. 11 (b), if the UE determines that the start symbol of the high PUSCH is earlier than the start symbol of any one of the plurality of low PUCCHs, the UE performs channel access at the RB set where the high PUSCH is located, and if the RB set where the high PUSCH is located detects that the channel is empty, the low PUCCH 1 and low PUCCH 2 transmissions are cancelled; if the RB set where the high PUSCH is located detects that the channel is busy and the channel detection is null in the RB set where the low PUCCH 1 is located, the UE transmits the low PUCCH 1, otherwise, the UE cancels the low PUCCH 1 transmission. The UE performs channel access within its RB set before the low PUCCH 2 transmission and transmits the low PUCCH 2 according to the detection result.

Scene c: as shown in fig. 11 (c), if the UE determines the start symbol of the high PUSCH is later than the start symbol of the earlier low PUCCH but earlier than the start symbol of the later low PUCCH, the UE cancels the low PUCCH 1 transmission, performs channel access in the RB set where the high PUSCH is located, and cancels the low PUCCH 2 transmission if the RB set where the high PUSCH is located detects that the channel is empty; if the RB set where the high PUSCH is located detects that the channel is busy, if the channel is detected to be empty in the RB set where the low PUCCH 2 is located, the UE transmits the low PUCCH 2, otherwise, the UE cancels the low PUCCH 2 transmission.

Based on the scheme, the UE can combine the initial time domain position of each uplink transmission with overlapped time domain resources and the transmission priority of each uplink transmission, and can adopt a plurality of different processing modes to determine and process each conflicting uplink transmission, so that the possibility of the UE transmitting the uplink transmission can be improved under the condition of overlapped uplink transmission time domain resources, and the probability of the UE accessing to a channel can be improved compared with the processing according to the priority of the uplink transmission in the related technology.

Optionally, in the embodiment of the present invention, the first uplink transmission includes M uplink transmissions, the second uplink transmission includes N uplink transmissions, and the uplink transmission information includes N channel access parameters corresponding to the uplink transmissions; m is a positive integer, and N is an integer greater than 1. Further, in the embodiment of the present invention, the above step 201 may be specifically performed by the following steps 201h1 to 201h 2:

step 201h1, the UE determines, according to the channel access parameters corresponding to the N uplink transmissions, and multiplexes a third uplink transmission with the highest priority.

Step 201h2, the UE multiplexes at least one uplink transmission of the M uplink transmissions for transmission in a third uplink transmission.

Wherein the multiplexing priority may also be determined according to at least one of: channel access parameters, whether aperiodic channel state information is carried, a starting time slot, a scheduling type, an index of a serving cell corresponding to uplink transmission and a transmission symbol position.

In general, one PUCCH may overlap with time domain resources of a plurality of N PUSCHs, in the related art, the UE may determine which PUSCH the UCI is multiplexed on according to a multiplexing priority rule of the related art, for example, to a PUSCH with an earlier starting symbol, for example, a PUSCH 1 with an earlier starting symbol, a corresponding channel access type of type 1, a PUSCH2 with a later starting symbol, and a corresponding channel access type of type 2C, that is, if the UE multiplexes UCI carried by the PUCCH on PUSCH2, it is affirmative that the UCI carried by the PUCCH can be transmitted, but if the UCI carried by the PUCCH is multiplexed on PUSCH 1, it is necessary to determine whether the UCI can be transmitted according to a channel detection result. In the unlicensed band, different PUSCHs may be in different serving cells (so that they correspond to different RBs set), so that the channel access parameters corresponding to the PUSCHs may be different, the PUSCH 1 corresponds to the type 1 channel access, and the PUSCH2 corresponds to the type 2C channel access in the COT shared by the base station, that is, the PUSCH2 can be transmitted without channel detection.

In the embodiment of the invention, the UE can determine which PUSCH to multiplex UCI to according to the priority corresponding to the channel access parameter, or can simultaneously use the priority corresponding to the channel access parameter and five multiplexing priority principles in the related technology to determine which PUSCH to multiplex UCI to. The priorities corresponding to the channel access parameters and the five multiplexing priorities in the related art may have different combinations, such as before the above-mentioned five multiplexing priorities or be inserted into the five multiplexing priorities. The priority corresponding to the channel access parameter may be set to any position before the 5 th priority.

Illustratively, the following 1 st multiplexing priority rule sets the priority corresponding to the channel access parameter as the highest priority, and the following 1 st multiplexing priority rule sets the priority corresponding to the channel access parameter as the next highest priority.

Multiplexing priority rule 1:

priority 0 (highest priority): PUSCH with high priority corresponding to channel access parameters > PUSCH with low priority corresponding to channel access parameters;

priority 1: PUSCH carrying a-CSI;

priority 2: PUSCH with earliest starting time slot;

Priority 3: dynamically scheduled PUSCH > configuration grant PUSCH or semi Persistent On PUSCH;

priority 4: the PUSCH with small index of the serving cell is the PUSCH with large index of the serving cell;

Multiplexing priority rule 2:

priority 1: PUSCH carrying a-CSI;

priority 1-2: PUSCH with high priority corresponding to channel access parameters > PUSCH with low priority corresponding to channel access parameters;

priority 2: PUSCH with earliest starting time slot;

In the foregoing embodiments, when the first uplink transmission includes M uplink transmissions and the second uplink transmission includes N uplink transmissions, if multiplexing transmission is required, multiplexing rule multiplexing provided in the embodiment of the present invention may be used for multiplexing the first uplink transmission and the second uplink transmission.

Based on the scheme, when the first uplink transmission includes M uplink transmissions and the second uplink transmission includes N uplink transmissions, the UE may determine how to multiplex at least one of the M uplink transmissions in the third uplink transmission based on the channel access parameters of the N uplink transmissions, which may be more flexible to select how to multiplex the transmissions.
