Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of wireless communication, and specifically relate to a method and device for multiplexing transmission of uplink information. BACKGROUND

[0002] The fifth generation (5 th generation,5G) mobile communication system is characterized by supporting ultra-reliable and low-latency communications (URLLC) services in comparison with the fourth generation (4 th generation,4G) mobile communication system.

[0003] With the introduction of URLLC services, some terminal devices will support both enhanced mobile broadband (eMBB) services and URLLC services. In the discussion process of the third generation partnership project (3 rd GenerationPartnership Project,3GPP) standard, multiplexing transmission between uplink data of different services or uplink control information corresponding to different services in the same terminal device is a problem to be solved. SUMMARY

[0004] Embodiments of the present application provide a method and device for multiplexing uplink information of different priorities, which avoids discarding uplink information carried in some low-priority uplink physical channels, thereby improving transmission efficiency.

[0005] In a first aspect, a method for uplink information multiplexing transmission is provided, which can be executed by a terminal device or a module in the terminal device, or can be executed by a network device or a module in the network device. Taking the terminal device as an example, the method comprises the following steps. The terminal device determines a set of uplink channels that need to be subjected to uplink information multiplexing transmission, the set of uplink channels comprising a first uplink channel and a second uplink channel, the first uplink channel being an uplink channel with the earliest starting time in the set of uplink channels, the first uplink channel having a first priority, the first uplink channel being used to carry first uplink information, the second uplink channel being an uplink channel with the earliest starting time among uplink channels with a second priority in the set of uplink channels, the second uplink channel satisfying a first condition with the first uplink channel, the second uplink channel being used to carry second uplink information, and the first priority being different from the second priority. The terminal device multiplexes and transmits the uplink information carried in the first uplink channel and the second uplink channel. The second uplink channel satisfying the first condition with the first uplink channel can also be referred to as satisfying a timing relationship.

[0006] In a possible implementation manner of the first aspect, the terminal device determines a first subset of uplink channels and a second subset of uplink channels, the uplink channels in the first subset of uplink channels being uplink channels other than the first uplink channel in the set of uplink channels, the uplink channels in the first subset of uplink channels having the same priority as the first uplink channel, the uplink channels in the first subset of uplink channels overlapping with the first uplink channel in the time domain, and the uplink channels in the first subset of uplink channels satisfying the first condition with the first uplink channel; the uplink channels in the second subset of uplink channels being uplink channels other than the second uplink channel in the set of uplink channels, the uplink channels in the second subset of uplink channels having the same priority as the second uplink channel, the uplink channels in the second subset of uplink channels overlapping with the second uplink channel in the time domain, and the uplink channels in the second subset of uplink channels satisfying the first condition with the second uplink channel, and the uplink channels in the second subset of uplink channels satisfying the first condition with the first uplink channel.

[0007] In a possible implementation manner of the first aspect, in a case where the first subset of uplink channels is not empty and the second subset of uplink channels is empty, the terminal device determines a third uplink channel to carry the first uplink information and the uplink information carried by the uplink channels in the first subset of uplink channels; and the terminal device multiplexes and transmits the uplink information carried in the third uplink channel and the second uplink channel.

[0008] In a possible implementation manner of the first aspect, in a case where the second subset of uplink channels is not empty and the first subset of uplink channels is empty, the terminal device determines a fourth uplink channel to carry the second uplink information and the uplink information carried by the uplink channels in the second subset of uplink channels; and the terminal device multiplexes and transmits the uplink information carried in the first uplink channel and the fourth uplink channel.

[0009] In a possible implementation of the first aspect, in the case where the first subset of uplink channels and the second subset of uplink channels are both non-empty, the third uplink channel is determined to carry the first uplink information and the uplink information carried by the uplink channels in the first subset of uplink channels, and the terminal device determines the fourth uplink channel to carry the second uplink information and the uplink information carried by the uplink channels in the second subset of uplink channels; and the terminal device multiplexes and transmits the uplink information carried in the third uplink channel and the fourth uplink channel.

[0010] By the above method, the terminal device multiplexes the uplink channels with the same priority first, and then multiplexes the two uplink channels with different priorities, thereby avoiding discarding the uplink information carried in some low-priority uplink channels, and improving the transmission efficiency.

[0011] In a possible implementation of the second aspect, the method can be executed by a terminal device or a module in the terminal device, or can be executed by a network device or a module in the network device. Taking the terminal device as an example, the method includes the following steps. The terminal device determines a set of uplink channels that need to be multiplexed and transmitted, and determines a first uplink channel with the earliest starting time in the set of uplink channels. The terminal device determines a third subset of uplink channels, the uplink channels in the third subset of uplink channels being the uplink channels in the set of uplink channels other than the first uplink channel and overlapping the first uplink channel in the time domain, and the uplink channels in the third subset of uplink channels satisfying a first condition with the first uplink channel. In the case where the third subset of uplink channels is an empty set, the terminal device sends the first uplink channel to the network device. In the case where the third subset of uplink channels is not an empty set, the terminal device determines a fifth uplink channel with the earliest starting time in the third subset of uplink channels. The terminal device multiplexes and transmits the information carried in the fifth uplink channel and the first uplink channel. By this method of judging whether the uplink channels in the third subset of uplink channels can be multiplexed with the first uplink channel one by one, the implementation can be simplified.

[0012] In a possible implementation of the second aspect, in the case where the fifth uplink channel and the first uplink channel have the same priority, the terminal device determines a sixth uplink channel, the sixth uplink channel being used to carry the uplink information carried in the fifth uplink channel and the first uplink channel. In the case where the fifth uplink channel and the first uplink channel have different priorities, the fifth uplink channel and the first uplink channel are processed according to a first rule.

[0013] In a possible implementation manner of the second aspect, the first rule is at least one of the following rules: the terminal device sends the uplink channel E to the network device on the condition that the first indication information indicates that the fifth uplink channel and the first uplink channel can be multiplexed; the terminal device sends the uplink channel with higher priority between the fifth uplink channel and the first uplink channel to the network device on the condition that the first indication information indicates that the fifth uplink channel and the first uplink channel cannot be multiplexed; the terminal device sends the uplink channel E to the network device on the condition that the ending symbol of the uplink channel E is not later than the ending symbol of the uplink channel with higher priority between the fifth uplink channel and the first uplink channel; the terminal device sends the uplink channel with higher priority between the fifth uplink channel and the first uplink channel to the network device on the condition that the ending symbol of the uplink channel E is later than the ending symbol of the uplink channel with higher priority between the fifth uplink channel and the first uplink channel; and the uplink channel E is used to carry uplink information carried by the fifth uplink channel and the first uplink channel.

[0014] In a third aspect, another method for uplink information multiplexing transmission is provided, which can be executed by a terminal device or a module in the terminal device, or can be executed by a network device or a module in the network device. Taking the terminal device as an example, the method includes the following steps. The terminal device determines a set of uplink channels that need to be subjected to uplink information multiplexing transmission, and determines a first uplink channel with the earliest starting time in the set of uplink channels. The terminal device determines a third uplink channel subset, the uplink channels in the third uplink channel subset being the uplink channels in the set of uplink channels other than the first uplink channel and overlapping the first uplink channel in the time domain, and the uplink channels in the third uplink channel subset satisfying a first condition with the first uplink channel. In the case that the third uplink channel subset is an empty set, the terminal device sends the first uplink channel to the network device. In the case that the third uplink channel subset is not an empty set, the terminal device multiplexes the uplink channels in the third uplink channel subset and the first uplink channel. This multiplexing manner can also be referred to as overall multiplexing, that is, all the uplink channels in the third uplink channel subset and the first uplink channel are taken as a whole to determine whether to multiplex and how to multiplex. By using this method, the number of times of determination of the UE and the base station can be reduced.

[0015] In a possible implementation manner of the third aspect, in the case that the priority of all the uplink channels in the third uplink channel subset is the same as the priority of the first uplink channel, the terminal device determines a sixth uplink channel for carrying uplink information carried by all the uplink channels in the third uplink channel subset and uplink information carried by the first uplink channel.

[0016] In a possible implementation form of the third aspect, in the case that the priority of at least one uplink channel in the third uplink channel subset is different from the priority of the first uplink channel, the terminal device determines the judgment of which uplink channels to multiplex and transmit according to the channel types of the first uplink channel and the uplink channels in the third uplink channel subset, and further determines whether multiplexing can be performed according to a predetermined rule.

[0017] In a fourth aspect, a communication apparatus is provided, which comprises modules for implementing the functions of the terminal device or the network device in the foregoing first aspect or any possible implementation form of the first aspect; or comprises modules for implementing the functions of the terminal device or the network device in the foregoing second aspect or any possible implementation form of the second aspect; or comprises modules for implementing the functions of the terminal device or the network device in the foregoing third aspect or any possible implementation form of the third aspect.

[0018] In a fifth aspect, a communication apparatus is provided, which comprises a processor and an interface circuit, the interface circuit being configured to receive a signal from another communication apparatus outside the communication apparatus and transmit the signal to the processor or send a signal from the processor to another communication apparatus outside the communication apparatus, and the processor being configured to implement the functions of the terminal device or the network device in the foregoing first aspect or any possible implementation form of the first aspect, the foregoing second aspect or any possible implementation form of the second aspect, or the foregoing third aspect or any possible implementation form of the third aspect, by means of a logic circuit or executing code instructions.

[0019] In a sixth aspect, a computer readable storage medium is provided, which stores a computer program or instructions, when the computer program or instructions are executed by a communication apparatus, implement the method in the foregoing first aspect or any possible implementation form of the first aspect, the foregoing second aspect or any possible implementation form of the second aspect, or the foregoing third aspect or any possible implementation form of the third aspect.

The terminal device can be fixed or mobile. Figure 1 This is only a schematic diagram, and the communication system can further include other network devices, such as a wireless relay device and a wireless backhaul device, which are not shown in Figure 1 . Embodiments of the present application do not limit the number of core network devices, radio access network devices, and terminal devices included in the mobile communication system.

[0028] The wireless access network device can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next generation NodeB (gNB) in a 5G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc. It can also be a module or unit that completes part of the functions of a base station, for example, it can be a central unit (CU) or a distributed unit (DU). The embodiments of the present application do not limit the specific technology and specific device form adopted by the wireless access network device. In the present application, the wireless access network device is referred to as a network device, and if not specified, the network device refers to the wireless access network device.

[0029] The terminal device can also be referred to as a terminal, user equipment (UE), mobile station, mobile terminal, etc. The terminal device can be a mobile phone, tablet computer, computer with wireless transceiver function, virtual reality terminal device, augmented reality terminal device, wireless terminal in industrial control, wireless terminal in unmanned driving, wireless terminal in remote surgery, wireless terminal in smart power grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal device.

[0030] The network device and the terminal device can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on water; can also be deployed on aircraft, balloons and artificial satellites in the air. The embodiments of the present application do not limit the application scenarios of the network device and the terminal device.

[0031] The network device and the terminal device can communicate through licensed spectrum, can also communicate through unlicensed spectrum, and can also communicate through licensed spectrum and unlicensed spectrum simultaneously. The network device and the terminal device can communicate through spectrum below 6 gigahertz (GHz), can also communicate through spectrum above 6 GHz, and can also communicate through spectrum below 6 GHz and spectrum above 6 GHz simultaneously. The embodiments of the present application do not limit the spectrum resources used between the network device and the terminal device.

[0032] In the embodiments of the present application, the time domain symbol can be an orthogonal frequency division multiplexing (OFDM) symbol or a Discrete Fourier Transform-spread-OFDM (DFT-s-OFDM) symbol. If not specified, the symbol in the embodiments of the present application refers to a time domain symbol.

[0033] It can be understood that, in the embodiments of the present application, the physical downlink shared channel (PDSCH), the physical downlink control channel (PDCCH), the physical uplink shared channel (PUSCH) and the physical uplink control channel (PUCCH) are only examples of the downlink data channel, the downlink control channel, the uplink data channel and the uplink control channel of the physical layer. In different systems and different scenarios, the data channel and the control channel can have different names, and the embodiments of the present application are not limited in this regard.

[0034] In the embodiments of the present application, the functions of the network device can also be performed by a module (such as a chip) in the network device, or by a control subsystem containing the functions of the base station. The control subsystem containing the functions of the base station can be a control center in an industrial Internet of Things application scenario such as smart grid, factory automation and intelligent transportation. The functions of the terminal device can also be performed by a module (such as a chip) in the terminal device.

[0035] For ease of description, the base station is taken as an example of the network device, and the UE is taken as an example of the terminal device in the present application. In order to communicate with the base station, the UE needs to establish a wireless connection with a cell controlled by the base station. The cell with which the UE establishes a wireless connection is referred to as a service cell of the UE. When the UE communicates with the service cell, it is also interfered by signals from neighboring cells.

[0036] In the present application, the base station sends a downlink signal or downlink information to the UE, and the downlink information is carried on a downlink channel; the UE sends an uplink signal or uplink information to the base station, and the uplink information is carried on an uplink channel.

[0037] In order to improve the reliability of data transmission, a hybrid automatic repeat request (HARQ) technology is supported in a new radio (NR) of a 5G mobile communication system. For downlink data transmission, after a terminal device receives data sent by a network device, if decoding of the data is successful, the terminal device feeds back an acknowledgement (ACK) to the network device; if decoding of the data fails, the terminal device feeds back a negative acknowledgement (NACK) to the network device. The ACK and the NACK can be collectively referred to as hybrid automatic repeat request-acknowledgment (HARQ-ACK) information. By using the HARQ technology, retransmitted data and initially transmitted data can be combined and decoded, thereby effectively improving the reliability of data transmission and the efficiency of data transmission.

[0038] Uplink information multiplexing transmission is a common technology, and two application scenarios are included in a protocol of a release 15 (R15) of 3GPP: (1) PUCCH#1 and PUCCH#2 overlap in the time domain, and uplink control information (UCI) carried by the two PUCCHs can be multiplexed and transmitted on PUCCH#3, where PUCCH#3 can be PUCCH#1 or PUCCH#2, or another PUCCH different from PUCCH#1 and PUCCH#2; (2) PUCCH#1 and PUSCH#1 overlap in the time domain, and UCI carried on PUCCH#1 can be multiplexed and transmitted on PUSCH#1 together with data carried on PUSCH#1. In the embodiments of the present application, overlap can include partial overlap and complete overlap, and partial overlap can also be understood as incomplete overlap. If not specifically stated, overlap in the embodiments of the present application refers to overlap in the time domain.

[0039] The main motivations for using such a multiplexing transmission mechanism include: (1) simultaneously sending two uplink channels that overlap in the time domain and are non-contiguous in the frequency domain can increase the peak-to-average ratio of the transmitted signal, thereby imposing higher requirements on the linear range of a power amplifier (PA) and increasing the cost of the PA; (2) if the two uplink channels do not completely overlap in the time domain, there will be a power jump at the interface between the two symbols before and after the overlap, thereby causing a phase discontinuity of the PA and resulting in that channel estimation on the symbols before the interface cannot be used for subsequent data demodulation.

[0040] The concept of physical layer priority is introduced in the protocol of Release 16 (R16) of 3GPP, which can be used to indicate the priority of the information transmitted on the physical channel, and can also be understood as indicating whether the information is URLLC service or eMBB service. In the embodiments of the present application, the physical layer priority can include two priorities of low priority (LP) PUCCH and high priority (HP) PUCCH.

[0041] Specifically, the priority of the information carried by different physical channels can be determined in the following manner.

[0042] For the PDSCH dynamically scheduled by the downlink control information (DCI), the priority of the HARQ-ACK information of the data on the PDSCH can be indicated by the priority indication field in the DCI. The bit length of the priority indication field in the DCI can be 1 bit. For the semi-persistent scheduling (SPS) PDSCH, the priority of the HARQ-ACK information of the data on the PDSCH can be indicated by the information element in the radio resource control (RRC) signaling configuring the SPS. The HARQ-ACK information can be carried on the PUCCH or the PUSCH.

[0043] The scheduling request (SR) is used for the UE to request the base station for uplink resources for uplink data transmission, and the beam failure recovery (BFR) is used for the UE to inform the base station that the current beam quality is poor and trigger the beam recovery process. The priority of the SR carried in the PUCCH can be indicated by the information element in the RRC signaling configuring the PUCCH resource. Similarly, the priority of the BFR carried in the PUCCH can also be indicated by the information element in the RRC signaling configuring the PUCCH resource.

[0044] Channel state information (CSI) includes periodic CSI (P-CSI), semi-persistent CSI (SP-CSI) and aperiodic CSI (A-CSI). Among them, P-CSI and SP-CSI carried on PUCCH can be low priority by default, the priority of SP-CSI carried on PUSCH can be indicated by the priority indication field in the DCI activating the SP-CSI, and the priority of A-CSI can be indicated by the priority indication field in the DCI triggering the A-CSI. P-CSI is usually carried on PUCCH, and SP-CSI and A-CSI can be carried on PUCCH or PUSCH.

[0045] For data carried on PUSCH, two scenarios are distinguished to determine its priority. For GB PUSCH dynamically scheduled by DCI, the priority of data carried on the GB PUSCH can be indicated by the priority indication field in the DCI. For CG PUSCH configured by RRC signaling, the priority of data carried on the CG PUSCH can be indicated by the information element in the RRC signaling configuring the CG.

[0046] In the embodiments of the present application, when only one priority information is carried in a physical channel, the priority of the information can also be understood as the priority of the physical channel, and the priority of the information and the priority of the physical channel carrying the information can be used interchangeably. There are four scenarios for multiplexing of uplink physical channels of different priorities. Scenario 1: multiplexing between LP PUCCH and HP PUCCH; Scenario 2: multiplexing between LP PUCCH and HP PUSCH; Scenario 3: multiplexing between LP PUSCH and HP PUCCH; Scenario 4: multiplexing between LP PUSCH and HP PUSCH. The embodiments of the present application focus on Scenario 1, Scenario 2 and Scenario 3. For these three scenarios, the UE can support multiplexing of UCI carried on two PUCCHs on one PUCCH, or can support multiplexing of UCI carried on one PUCCH and data carried on one PUSCH on the PUSCH.

[0047] After 3GPP R16 protocol introduces physical layer priority, for two uplink physical channels with the same priority, multiplexing transmission can be performed according to the rules defined in R15 protocol; for two uplink physical channels with different priorities that overlap in the time domain, the UE only transmits the uplink physical channel with high priority on the overlapping symbol, and cancels the transmission of the uplink physical channel with low priority.

[0048] As shown in a scenario of multiplexing of three uplink physical channels, the UE will first process the overlapping LP PUCCH and DCI#1 scheduled HP PUxCH in the time domain according to the time sequence, and the UE will discard the information carried on the LP PUCCH, that is, will not transmit the information carried on the LP PUCCH. Even if a LP PUxCH overlapping with the LP PUCCH appears later, the UE will not multiplex the LP PUCCH and the LP PUxCH. In the embodiments of the present application, PUxCH refers to PUCCH or PUSCH. Figure 2

[0049] As shown in another scenario of multiplexing of three uplink physical channels, the UE will first process the overlapping LP PUxCH and DCI#1 scheduled HP PUCCH in the time domain according to the time sequence, and the UE will discard the information carried on the LP PUxCH, that is, will not transmit the information carried on the LP PUxCH. Even if a DCI#2 scheduled HP PUxCH overlaps with the HP PUCCH in the time domain, the UE will multiplex the information transmitted on the HP PUCCH to the HP PUxCH for transmission, so as to actually not transmit the HP PUCCH, but also will not retransmit the LP PUxCH. Figure 3

[0050] In view of the deficiencies of the prior art in scenarios similar to Figure 2 and Figure 3 The embodiments of the present application provide a multiplexing method of multiple uplink physical channels with different priorities, which can avoid discarding the uplink information to be transmitted as much as possible, and improve the utilization and transmission efficiency of the uplink physical channel. For multiplexing of multiple uplink physical channels with different priorities, the general principle is to first process multiplexing of uplink physical channels with the same priority, and then process multiplexing of uplink physical channels with different priorities.

[0051] Figure 4 A flowchart of a method for multiplexing transmission of multiple uplink physical channels with different priorities is provided in the embodiments of the present application. The flowchart will be described in detail below. The flowchart can be executed at the base station and the UE respectively.

[0052] ​​S410, the base station and the UE determine the set of uplink channels that need to be used for uplink information multiplexing transmission. The set of uplink channels includes a first uplink channel and a second uplink channel. The first uplink channel is the uplink channel with the earliest start time in the set of uplink channels. The first uplink channel has the first priority and is used to carry the first uplink information. The second uplink channel is the uplink channel with the second priority in the set of uplink channels with the earliest start time. The second uplink channel and the first uplink channel satisfy the first condition. The second uplink channel is used to carry the second uplink information. The first priority and the second priority are different.

[0053] Specifically, the base station and UE can determine the uplink channel set within a time slot; that is, the uplink channels to be transmitted within the same time slot constitute the uplink channel set. If multiple uplink channels have the same start time and are the uplink channels with the earliest start time in the uplink channel set, one of these uplink channels with the earliest start time can be selected as the first uplink channel. The specific selection rule can be at least one of the following: randomly select one; select the uplink channel with the longest time domain length; or select the PUCCH carrying HARQ-ACK.

[0054] S420, the base station and UE multiplex the uplink information carried in the first uplink channel and the second uplink channel for transmission.

[0055] In embodiments of this application, transmission may include sending and receiving. For example, both the UE sending the uplink information and the base station receiving the uplink information can be collectively referred to as transmitting uplink information.

[0056] like Figure 5 As shown, before the base station and UE perform multiplexing transmission of the uplink information carried in the first uplink channel and the second uplink channel, the multiplexing transmission method may further include S411.

[0057] S411, the base station and the UE determine a first subset of uplink channels subset#1, the uplink channels in the first subset of uplink channels are the uplink channels in the set of uplink channels except the first uplink channel, the priority of the uplink channels in the first subset of uplink channels is the same as the priority of the first uplink channel, the uplink channels in the first subset of uplink channels overlap with the first uplink channel in the time domain, and the uplink channels in the first subset of uplink channels satisfy the first condition with the first uplink channel; the base station and the UE determine a second subset of uplink channels subset#2, the uplink channels in the second subset of uplink channels are the uplink channels in the set of uplink channels except the second uplink channel, the priority of the uplink channels in the second subset of uplink channels is the same as the priority of the second uplink channel, the uplink channels in the second subset of uplink channels overlap with the second uplink channel in the time domain, the uplink channels in the second subset of uplink channels satisfy the first condition with the second uplink channel, and the uplink channels in the second subset of uplink channels satisfy the first condition with the first uplink channel.

[0058] Optionally, the uplink channels in the first subset of uplink channels can also be the uplink channels in the set of uplink channels except the first uplink channel, the priority of the uplink channels in the first subset of uplink channels is the same as the priority of the first uplink channel, and the uplink channels in the first subset of uplink channels overlap with the first uplink channel in the time domain.

[0059] Further, as shown in S412, the base station and the UE can determine whether subset#1 and subset#2 are empty.

[0060] In the case that the first subset of uplink channels is not empty and the second subset of uplink channels is empty, the base station and the UE multiplex and transmit the information carried in the first uplink channel and the second uplink channel, specifically including: S413a, the base station and the UE determine a third uplink channel for carrying the first uplink information and the uplink information carried by the uplink channels in the first subset of uplink channels; S420a, the base station and the UE multiplex and transmit the uplink information carried in the third uplink channel and the second uplink channel.

[0061] In the case that the second subset of uplink channels is not empty and the first subset of uplink channels is empty, the base station and the UE multiplex and transmit the information carried in the first uplink channel and the second uplink channel, specifically including: S413b, the base station and the UE determine a fourth uplink channel for carrying the second uplink information and the uplink information carried by the uplink channels in the second subset of uplink channels; S420b, the base station and the UE multiplex and transmit the uplink information carried in the first uplink channel and the fourth uplink channel.

[0062] In the case that the first uplink channel subset and the second uplink channel subset are both not empty, the base station and the UE multiplex and transmit the uplink information carried in the first uplink channel and the second uplink channel, specifically including: S413c, the base station and the UE determine that the third uplink channel is used to carry the first uplink information and the uplink information carried by the uplink channel in the first uplink channel subset, and determine that the fourth uplink channel is used to carry the second uplink information and the uplink information carried by the uplink channel in the second uplink channel subset; S420c, the base station and the UE multiplex and transmit the uplink information carried in the third uplink channel and the fourth uplink channel.

[0063] In the case that the first uplink channel subset and the second uplink channel subset are both empty, the base station and the UE can directly multiplex and transmit the uplink information carried in the first uplink channel and the second uplink channel.

[0064] Specifically, in the case that the third uplink channel is neither the uplink channel in the first uplink channel subset nor the first uplink channel, the UE can not transmit the uplink channel in the first uplink channel subset and the first uplink channel to the base station, and correspondingly, the base station does not receive the uplink channel in the first uplink channel subset and the first uplink channel. That is, the time-frequency resources of the third uplink channel determined in S413a or S413c are different from the time-frequency resources of the uplink channel in the first uplink channel subset and the time-frequency resources of the first uplink channel. At this time, the information originally carried in the uplink channel in the first uplink channel subset and the information originally carried in the first uplink channel are both carried in the newly determined third uplink channel. The original uplink channel in the first uplink channel subset and the first uplink channel are no longer transmitted. The time-frequency resources of the third uplink channel can be determined according to the bit quantity of the information carried in the third uplink channel and the related configuration parameters. Of course, the third uplink channel can also be a certain uplink channel in the first uplink channel subset, or can also be the first uplink channel. At this time, among the uplink channel in the first uplink channel subset and the first uplink channel, the UE does not transmit other uplink channels except the third uplink channel to the base station.

[0065] Similarly, in the case that the fourth uplink channel is neither the uplink channel in the second uplink channel subset nor the second uplink channel, the UE can not transmit the uplink channel in the second uplink channel subset and the second uplink channel to the base station. That is, the time-frequency resources of the fourth uplink channel determined in S413b or S413c are different from the time-frequency resources of the uplink channel in the second uplink channel subset and the time-frequency resources of the second uplink channel. Of course, the fourth uplink channel can also be a certain uplink channel in the second uplink channel subset, or can also be the second uplink channel. At this time, among the uplink channel in the second uplink channel subset and the second uplink channel, the UE does not transmit other uplink channels except the fourth uplink channel to the base station.

[0066] The following describes the process of determining the third uplink channel in the multiplexing process of multiple uplink channels with the same priority in S413a, S413b and S413c, taking the determination of the third uplink channel as an example. The fourth uplink channel is determined in the same way as the third uplink channel.

[0067] In scenario a, under the condition that the first uplink channel and the uplink channels in the first uplink channel subset are all PUCCH, the third uplink channel determined by the base station and the UE is also PUCCH. The time-frequency resources of the third uplink channel can be the same as or different from those of any of the first uplink channel and the uplink channels in the first uplink channel subset.

[0068] In scenario b, under the condition that the first uplink channel is PUCCH and all the uplink channels in the first uplink channel subset are PUSCH, the base station and the UE determine the third uplink channel from the first uplink channel subset to carry the first uplink information and the uplink information in the third uplink channel. Optionally, the third uplink channel is the uplink channel with the earliest starting time in the first uplink channel subset.

[0069] In scenario c, under the condition that the first uplink channel is PUCCH and the first uplink channel subset includes both PUCCH and PUSCH, the base station and the UE determine the third uplink channel to carry the first uplink information and the uplink information carried by all the PUCCH in the first uplink channel subset.

[0070] Optionally, when the third uplink channel overlaps in the time domain with one or more PUSCH in the first uplink channel subset, the base station and the UE can also determine an eighth uplink channel to carry the uplink information carried by the third uplink channel and the uplink information carried by the eighth uplink channel, where the eighth uplink channel is the PUSCH with the earliest starting time among the PUSCHs overlapping with the third uplink channel. The eighth uplink channel is used as the third uplink channel in S413a and S413c.

[0071] Scenario d, on the condition that the first uplink channel is PUSCH and all uplink channels in the first uplink channel subset are PUCCH, the base station and the UE take the first uplink channel as the third uplink channel for carrying the first uplink information and the uplink information carried by the uplink channels in the first uplink channel subset. Alternatively, on the condition that multiple PUCCHs in the first uplink channel subset overlap, the base station and the UE determine the ninth uplink channel for carrying the uplink information carried by the uplink channels in the first uplink channel subset. Optionally, when the ninth uplink channel and the first uplink channel overlap, the base station and the UE determine to use the first uplink channel for carrying the first uplink information and the uplink information carried by the ninth uplink channel. And take the first uplink channel as the third uplink channel in S413a and S413c.

[0072] Scenario e, on the condition that the first uplink channel is PUSCH and all uplink channels in the first uplink channel subset are PUSCH, the base station and the UE expect the first uplink channel subset to be empty.

[0073] Scenario f, on the condition that the first uplink channel is PUSCH and the first uplink channel subset contains both PUCCH and PUSCH, the base station and the UE determine to use the first uplink channel for carrying the first uplink information and the uplink information carried by the PUCCH in the first uplink channel subset. Alternatively, on the condition that multiple PUCCHs in the first uplink channel subset overlap, the base station and the UE determine the ninth uplink channel for carrying the uplink information carried by the PUCCH in the first uplink channel subset. Optionally, when the ninth uplink channel and the first uplink channel overlap, the base station and the UE determine to use the first uplink channel for carrying the first uplink information and the uplink information carried by the ninth uplink channel. And take the first uplink channel as the third uplink channel in S413a and S413c.

[0074] The first condition mentioned in S410 is described as follows. The first condition is satisfied when: when one of the uplink channel A and the uplink channel B is a PUCCH and the PUCCH is used to carry hybrid automatic repeat request acknowledgement (HARQ-ACK) information, a distance between a reference symbol and an ending symbol of a first physical downlink shared channel (PDSCH) is greater than or equal to a first threshold, where the reference symbol is a symbol with an earlier starting time among a starting symbol of the uplink channel A and a starting symbol of the uplink channel B, the first PDSCH is a PDSCH corresponding to the HARQ-ACK information, and the first threshold is related to at least one of a subcarrier spacing of the first PDSCH, a time domain length of the first PDSCH, a mapping type of the first PDSCH, and a UE capability; and when one of the uplink channel A and the uplink channel B is a PUSCH, a distance between the reference symbol and an ending symbol of a first PDCCH is greater than or equal to a second threshold, where the first PDCCH is a PDCCH corresponding to the PUSCH, and the second threshold is related to at least one of a subcarrier spacing of the PUSCH, a mapping type of the PUSCH, and a UE capability. The uplink channel A and the uplink channel B are uplink channels in a set of uplink channels. The HARQ-ACK information is ACK / NACK information of data carried in the first PDSCH. When the PUSCH is a GB PUSCH, a DCI in the first PDCCH is used to schedule the GB PUSCH. When the PUSCH is a type-2 CG PUSCH, a DCI in the first PDCCH is used to activate the CG PUSCH.

[0075] The first threshold T1 = N1 + d 1,1 , where N1 is related to at least one of a subcarrier spacing of the first PDSCH and a UE capability, and d 1,1 is related to at least one of a time domain length of the first PDSCH and a mapping type of the first PDSCH. N1 + d 1,1 is an integer greater than or equal to zero. N1 + d 1,1 is used to ensure that the UE has enough time to generate the HARQ-ACK and complete the preparation for transmission after receiving the PDSCH. The additional 1 symbol is a processing delay introduced especially for multiplexing multiple channels.

[0076] The second threshold T2 = N2 + d 2,1 + 1, where N2 is related to at least one of a subcarrier spacing of the PUSCH and a UE capability, and d 2,1 is related to a mapping type of the PUSCH. N2 + d 2,1is used to ensure that the UE has enough time to complete the preparation of PUSCH transmission after receiving the DCI, and the additional 1 symbol is introduced for processing delay of multiple channel multiplexing.

[0077] The first condition here can also be understood as a timing condition for multiplexing of multiple uplink channels. For multiplexing of PUCCH and PUCCH, the main consideration is whether the multiplexed PUCCH can meet the timing requirement of feeding back HARQ-ACK information. If none of the PUCCHs carries HARQ-ACK information, but only carries SR or CSI, it is considered that no timing condition is required, i.e., the first condition is met by default. For multiplexing of PUCCH and PUSCH, in addition to considering whether the multiplexed PUSCH can meet the timing requirement of PUSCH itself, it is also necessary to consider whether the timing requirement of HARQ-ACK information can be met.

[0078] The multiplexing and transmission of uplink information in S420, S420a, S420b and S420c described above will be described in detail below. Multiplexing and transmission of uplink information carried in uplink channel C and uplink channel D includes: under the condition that uplink channel C and uplink channel D overlap in time domain, processing uplink channel C and uplink channel D according to the first rule; and / or under the condition that uplink channel C and uplink channel D do not overlap in time domain, transmitting uplink channel C and uplink channel D. Wherein, the uplink channel C is the first uplink channel or the third uplink channel, and the uplink channel D is the second uplink channel or the fourth uplink channel. In the embodiments of the present application, multiplexing or multiplexing transmission of two uplink channels can also be referred to as multiplexing uplink information carried in the two uplink channels into one of the two uplink channels for transmission, or multiplexing into other uplink channels for transmission.

[0079] The first rule is at least one of rule 1a, rule 1b, rule 1c, rule 1d, rule 1e, and rule 1f. For example, the first rule can be one of rule 1a, 1b, 1c, 1d, 1e, and 1f; the first rule can also be a combination of two of rule 1a, 1c, and 1e, or a combination of two of rule 1b, 1d, and 1f; the first rule can also be a combination of three of rule 1a, 1c, and 1e, or a combination of three of rule 1b, 1d, and 1f. The first rule here is to determine whether different priority physical channels can be multiplexed for transmission. Multiplexing of different priorities can cause an increase in transmission delay or a decrease in reliability of high-priority PUCCH transmission. Whether multiplexing of different priorities can be performed can be indicated by the base station to the UE by signaling, or can be determined by whether multiplexing will cause an increase in transmission delay or a decrease in reliability of high-priority information transmission. In the embodiments of the present application, if not otherwise specified, the signaling can be RRC signaling, MAC signaling, or physical layer signaling (for example, DCI). The high-layer signaling can be RRC signaling or MAC signaling.

[0080] Rule 1a: under the condition that the first indication information indicates that uplink channel C and uplink channel D can be multiplexed, the UE transmits uplink channel E to the base station, and the UE does not transmit uplink channel C and uplink channel D to the base station. The first indication information here can be transmitted by the base station to the UE in signaling, and is used to indicate whether the uplink channel (uplink channel C or uplink channel D) can be multiplexed for transmission with other priority uplink channels, or can be understood as being used to indicate whether the uplink information carried in the uplink channel (uplink channel C or uplink channel D) can be multiplexed for transmission with other priority uplink information.

[0081] Rule 1b: under the condition that the first indication information indicates that uplink channel C and uplink channel D cannot be multiplexed, the UE can transmit the uplink channel with higher priority of uplink channel C and uplink channel D to the base station, and the UE can not transmit the uplink channel with lower priority of uplink channel C and uplink channel D and the uplink information carried in the uplink channel with lower priority of uplink channel C and uplink channel D to the base station.

[0082] Rule 1c: under the condition that the end symbol of uplink channel E is not later than the end symbol of the uplink channel with higher priority of uplink channel C and uplink channel D, the UE transmits uplink channel E to the base station. The UE does not transmit uplink channel C and uplink channel D to the base station.

[0083] Rule 1d, on the condition that the ending symbol of the uplink channel E is later than the ending symbol of the uplink channel with higher priority among the uplink channel C and the uplink channel D, the UE can send the uplink channel with higher priority among the uplink channel C and the uplink channel D to the base station, and the UE does not send the uplink channel with lower priority among the uplink channel C and the uplink channel D and the uplink information carried by the uplink channel with lower priority among the uplink channel C and the uplink channel D to the base station.

[0084] Rule 1e, on the condition that the coding rate of the uplink channel E is not greater than the coding rate of the uplink channel with higher priority among the uplink channel C and the uplink channel D, the UE sends the uplink channel E to the base station. The UE does not send the uplink channel C and the uplink channel D to the base station. Wherein, on the condition that the uplink information of different priorities are independently coded respectively, the coding rate of the uplink channel E can be the coding rate of the high-priority uplink information in the uplink channel E.

[0085] Rule 1f, on the condition that the coding rate of the uplink channel E is greater than the coding rate of the uplink channel with higher priority among the uplink channel C and the uplink channel D, the UE can send the uplink channel with higher priority among the uplink channel C and the uplink channel D to the base station, and the UE does not send the uplink channel with lower priority among the uplink channel C and the uplink channel D and the uplink information carried by the uplink channel with lower priority among the uplink channel C and the uplink channel D to the base station.

[0086] The above-mentioned uplink channel E is an uplink channel determined by the UE to carry the uplink information carried by the uplink channel C and the uplink channel D. The time-frequency resource of the uplink channel E can be the same as, partially the same as, or completely different from the time-frequency resource of the uplink channel C or the uplink channel D.

[0087] The combination of the above-mentioned rules is illustrated below by taking the combination of rule 1a and rule 1c as an example. The combination of rule 1a and rule 1c: on the condition that the first indication information indicates that the uplink channel C and the uplink channel D can be multiplexed, and the ending symbol of the uplink channel E is not later than the ending symbol of the uplink channel with higher priority among the uplink channel C and the uplink channel D, the UE sends the uplink channel E to the base station. The UE does not send the uplink channel C and the uplink channel D to the base station.

[0088] In the embodiments of the present application, the uplink channels in the set of uplink channels are all physical channels, for example, PUCCH or PUSCH. The first priority is indicated by a field in the first DCI corresponding to the first uplink channel or indicated by a field element in the RRC signaling configuring the first uplink channel. The second priority is indicated by a field in the second DCI corresponding to the second uplink channel or indicated by a field element in the RRC signaling configuring the second uplink channel. Specifically, the determination method of the first priority and the second priority can refer to the determination method of the priority of the information carried by the aforementioned physical channel.

[0089] Figure 6 Another possible implementation of the embodiments of the present application is provided Figure 4 and Figure 5 Another possible implementation of the embodiments of the present application is provided Figure 6 The detailed description of S601-S615 in the above Figure 4 and Figure 5 The detailed description of S601-S615 in the above Figure 6 The numbering order in the above does not limit the code execution order in actual product implementation. For example, S603 and S604 can be executed after S605, or can be executed after S606, S607 or S612.

[0090] The above Figure 4 , Figure 5 and Figure 6 The above uplink channel multiplexing method provided in the embodiments of the present application allows uplink channels with the same priority to be multiplexed first, and then multiplexes uplink channels with different priorities, avoiding the contents carried in some low-priority uplink channels from being discarded, thereby improving the transmission efficiency.

[0091] Figure 7 Another method flow diagram for multiplexing and transmitting a plurality of uplink physical channels with different priorities is provided in the embodiments of the present application. The flow can be executed at the base station and the UE side respectively.

[0092] S701, the base station and the UE determine a set of uplink channels that need to be multiplexed and transmitted.

[0093] S702, the base station and the UE determine a first uplink channel with the earliest starting time in the set of uplink channels.

[0094] The specific process of S701 and S702 can refer to the related description in S410.

[0095] S703, the base station and the UE determine a third subset of uplink channels subset#3. The uplink channels in the third subset of uplink channels are the uplink channels in the set of uplink channels other than the first uplink channel, which overlap with the first uplink channel in the time domain, and the uplink channels in the third subset of uplink channels satisfy the first condition with the first uplink channel. For detailed description of the first condition, please refer to Figure 4 The description of the first condition in the embodiment. The priority of the uplink channels in the third subset of uplink channels can be the same as the priority of the first uplink channel, or can be different from the priority of the first uplink channel.

[0096] S704, the base station and the UE determine whether the third subset of uplink channels is empty.

[0097] S705, in the case that the third subset of uplink channels is empty, the UE transmits the first uplink channel to the base station.

[0098] S706, in the case that the third subset of uplink channels is not empty, the base station and the UE determine a fifth uplink channel in the third subset of uplink channels, which has the earliest starting time.

[0099] If there are multiple uplink channels in the third subset of uplink channels, which have the same starting time and are the uplink channels with the earliest starting time in the third subset of uplink channels, one of the uplink channels with the earliest starting time can be selected as the fifth uplink channel. The specific selection rule can be at least one of the following rules: randomly selecting one; selecting the uplink channel with the longest time length; or selecting the uplink channel with the same priority as the first uplink channel.

[0100] S707, the base station and the UE multiplex the fifth uplink channel and the first uplink channel for transmission, i.e., multiplex the information carried in the fifth uplink channel and the first uplink channel for transmission.

[0101] In the case that the priority of the fifth uplink channel and the first uplink channel is the same, a sixth uplink channel is determined, which is used to carry the uplink information carried in the fifth uplink channel and the first uplink channel. When the sixth uplink channel is not the first uplink channel and is not the fifth uplink channel, the UE does not transmit the fifth uplink channel and the first uplink channel to the base station. Correspondingly, the base station receives the sixth uplink channel from the UE. The base station does not receive the fifth uplink channel and the first uplink channel.

[0102] In the case that the priority of the fifth uplink channel and the first uplink channel is different, the first rule is used to process the fifth uplink channel and the first uplink channel. For detailed description of the first rule, please refer to Figure 4 The description of the first rule in the embodiment.

[0103] After the execution of S707 is completed, the sixth uplink channel is taken as an uplink channel to be sent, and the base station and the UE continue to execute S702.

[0104] Figure 7 The embodiment provides a method of judging whether to multiplex one by one, which can simplify the implementation.

[0105] S706 and S707 can also be replaced by S806 in Figure 8

[0106] S806, the uplink channels in the third uplink channel subset and the first uplink channel are multiplexed. This multiplexing method can also be called overall multiplexing, that is, all uplink channels in the third uplink channel subset and the first uplink channel are taken as a whole to judge whether to multiplex and how to multiplex. By using this method, the number of times of judgment of the UE and the base station can be reduced.

[0107] In the case where the priority of all uplink channels in the third uplink channel subset is the same as the priority of the first uplink channel, the sixth uplink channel is determined to carry the uplink information carried by all uplink channels in the third uplink channel subset and the uplink information carried by the first uplink channel. The UE sends the sixth uplink channel to the base station. When the sixth uplink channel is neither the first uplink channel nor any uplink channel in the third uplink channel subset, the UE does not send all uplink channels in the third uplink channel subset and the first uplink channel to the base station. In the embodiment of the present application, the UE does not send a certain uplink channel, which can also be called that the UE discards a certain uplink channel.

[0108] In the case where at least one uplink channel in the third uplink channel subset has a priority different from the priority of the first uplink channel, the base station and the UE determine whether all uplink channels in the third uplink channel subset and the first uplink channel can be multiplexed according to at least one of the rules A1, A2, A3, B1, B2, C1 and C2. For example, it can be determined according to one of the rules A1, A2, A3, B1, B2, C1 and C2; or it can be determined according to at least two of the rules A1, B1 and C1, or at least two of the rules A1, B2 and C2; or it can be determined according to at least two of the rules A2, B1 and C1, or at least two of the rules A2, B2 and C2; or it can be determined according to at least two of the rules A3, B1 and C1, or at least two of the rules A3, B2 and C2.

[0109] ​Rule A1, for each uplink channel, the base station sends signaling to the UE to indicate whether it can be multiplexed with other priority uplink channels. The UE first determines whether all uplink channels in the third uplink channel subset and the first uplink channel can be multiplexed according to the indication information (e.g., the first field) in the DCI. Specifically, it can be subdivided into three scenarios for description.

[0110] Scenario A1-1, if only one of the uplink channels in the third uplink channel subset and the first uplink channel is scheduled or triggered by the DCI, the UE determines whether the uplink channels in the third uplink channel subset and the first uplink channel can be multiplexed for transmission according to the value of the first field in the DCI.

[0111] Scenario A1-2, if multiple uplink channels in the third uplink channel subset and the first uplink channel are scheduled or triggered by the DCI, the UE can determine whether the uplink channels in the third uplink channel subset and the first uplink channel can be multiplexed for transmission according to at least one of the following rules.

[0112] Rule A1-2a, select one DCI from the above-mentioned multiple DCIs scheduling or triggering uplink channels, and determine whether the uplink channels in the third uplink channel subset and the first uplink channel can be multiplexed for transmission according to the value of the first field in the DCI. The DCI can be selected according to at least one of the following selection strategies: preferentially select the DCI corresponding to the uplink channel with high priority; preferentially select the DCI with a later time domain position. Here, the time domain position can be the starting symbol position or the ending symbol position of the PDCCH carrying the DCI.

[0113] Rule A1-2b, the UE can determine that the uplink channels in the third uplink channel subset and the first uplink channel can be multiplexed for transmission only when the values of the first field in the above-mentioned multiple DCIs all indicate that they can be multiplexed with other priority uplink channels.

[0114] Rule A1-2c, the UE can determine that the uplink channels in the third uplink channel subset and the first uplink channel can be multiplexed for transmission only when the values of the first field in the DCIs corresponding to all high-priority uplink channels all indicate that they can be multiplexed with other priority uplink channels.

[0115] Scenario A1-3, if all uplink channels in the third uplink channel subset and the first uplink channel are configured by high-layer signaling, determine whether the uplink channels in the third uplink channel subset and the first uplink channel can be multiplexed for transmission according to the values of the indication information (e.g., the first field) in all high-layer signaling configuring these uplink channels. Specifically, the UE can determine whether the uplink channels in the third uplink channel subset and the first uplink channel can be multiplexed for transmission according to one of the following rules.

[0116] Rule A1-3a, when the value of the first information element in all high layer signaling configuring these uplink channels indicates that the uplink channels of the third uplink channel subset can be multiplexed with the first uplink channel, the UE determines that the uplink channels of the third uplink channel subset and the first uplink channel can be multiplexed for transmission.

[0117] Rule A1-3b, when the value of the first information element in all high layer signaling configuring all high priority uplink channels indicates that the uplink channels of the third uplink channel subset can be multiplexed with the first uplink channel, the UE determines that the uplink channels of the third uplink channel subset and the first uplink channel can be multiplexed for transmission.

[0118] Rule A2, for each uplink channel, the base station sends signaling to the UE indicating whether the uplink channel can be multiplexed with uplink channels of other priorities. The UE determines whether the uplink channels of the third uplink channel subset and the first uplink channel can be multiplexed for transmission according to the indication information corresponding to the high priority uplink channels. Specifically, it can be divided into three scenarios for description.

[0119] Scenario A2-1, if there is only one high priority uplink channel in the third uplink channel subset and the first uplink channel that is DCI scheduled or triggered, the UE determines whether the uplink channels of the third uplink channel subset and the first uplink channel can be multiplexed for transmission according to the value of the first field in the DCI.

[0120] Scenario A2-2, if there are multiple high priority uplink channels in the third uplink channel subset and the first uplink channel that are DCI scheduled or triggered, the UE can determine whether the uplink channels of the third uplink channel subset and the first uplink channel can be multiplexed for transmission according to at least one of the following rules.

[0121] Rule A2-2a, select the DCI with the earliest time domain position, and determine whether the uplink channels of the third uplink channel subset and the first uplink channel can be multiplexed for transmission according to the value of the first field in the DCI. The time domain position here can be the starting symbol position or the ending symbol position of the PDCCH carrying the DCI.

[0122] Rule A2-2b, when the value of the first field in all DCIs corresponding to high priority uplink channels indicates that the uplink channels of the third uplink channel subset can be multiplexed with the first uplink channel, it is determined that the uplink channels of the third uplink channel subset and the first uplink channel can be multiplexed for transmission.

[0123] Scenario A2-3, if the uplink channels in the third subset of uplink channels and the high priority uplink channels in the first subset of uplink channels are all configured by high layer signaling, the UE determines whether the uplink channels in the third subset of uplink channels and the first subset of uplink channels can be multiplexed for transmission according to the indication information (e.g., the first information element) in all the high layer signaling configuring these high priority uplink channels. When the indication information in all the high layer signaling configuring these high priority uplink channels indicates that the uplink channels can be multiplexed with other priority uplink channels, the UE determines that the uplink channels in the third subset of uplink channels and the first subset of uplink channels can be multiplexed for transmission. When one of the indication information in all the high layer signaling configuring these high priority uplink channels indicates that the uplink channels cannot be multiplexed with other priority uplink channels, the UE determines that the uplink channels in the third subset of uplink channels and the first subset of uplink channels cannot be multiplexed for transmission.

[0124] Rule A3, for each uplink channel, the base station sends signaling to the UE indicating whether the uplink channel can be multiplexed with other priority uplink channels. The UE determines whether the uplink channels in the third subset of uplink channels and the first subset of uplink channels can be multiplexed for transmission according to the indication information corresponding to the first subset of uplink channels and the third subset of uplink channels. The indication information can be a first field in DCI or a first information element in high layer signaling. Specifically, when the indication information corresponding to the first subset of uplink channels and the third subset of uplink channels indicates that the uplink channels can be multiplexed with other priority uplink channels, the UE determines that the uplink channels in the third subset of uplink channels and the first subset of uplink channels can be multiplexed for transmission. When one of the indication information corresponding to the first subset of uplink channels and the third subset of uplink channels indicates that the uplink channels cannot be multiplexed with other priority uplink channels, the UE determines that the uplink channels in the third subset of uplink channels and the first subset of uplink channels cannot be multiplexed for transmission.

[0125] Rule B1, in the case that the ending symbol of the sixth uplink channel is not later than the ending symbol of all high priority uplink channels among the first subset of uplink channels and the third subset of uplink channels, it is determined that the UE can multiplex the first subset of uplink channels and the third subset of uplink channels for transmission.

[0126] Rule B2, in the case that the ending symbol of the sixth uplink channel is later than the ending symbol of the seventh uplink channel, it is determined that the UE cannot multiplex the first subset of uplink channels and the third subset of uplink channels for transmission. The seventh uplink channel is a high priority uplink channel among the first subset of uplink channels and the third subset of uplink channels.

[0127] Rule C1, on the condition that the coding rate of the sixth uplink channel is not greater than the coding rate of all uplink channels in the third uplink channel subset and all high-priority uplink channels in the first uplink channel, it is determined that the UE can multiplex the uplink channels in the third uplink channel subset and the first uplink channel for transmission. Wherein, on the condition that the uplink information of different priorities is independently coded respectively, the coding rate of the sixth uplink channel can be the coding rate of the high-priority uplink information in the sixth uplink channel.

[0128] Rule C2, on the condition that the coding rate of the sixth uplink channel is greater than the coding rate of the seventh uplink channel, it is determined that the UE cannot multiplex the uplink channels in the third uplink channel subset and the first uplink channel for transmission.

[0129] The sixth uplink channel described above is the uplink channel determined by the UE to carry the uplink information carried by all uplink channels in the third uplink channel subset and the uplink information carried by the first uplink channel.

[0130] The combination of the above rules is illustrated below by taking the combination of rules B1 and C1 as an example. The combination of rule B1 and rule C1: on the condition that the ending symbol of the sixth uplink channel is not later than the ending symbol of all uplink channels in the third uplink channel subset and all high-priority uplink channels in the first uplink channel, and the coding rate of the sixth uplink channel is not greater than the coding rate of all uplink channels in the third uplink channel subset and all high-priority uplink channels in the first uplink channel, it is determined that the UE can multiplex the uplink channels in the third uplink channel subset and the first uplink channel for transmission.

[0131] The base station and the UE can determine the judgment of multiplexing transmission of which uplink channels according to the channel type of the first uplink channel and the uplink channels in the third uplink channel subset (here, the channel type includes PUCCH and PUSCH). The above S806 is further described below according to different scenarios.

[0132] Scenario S1: when the first uplink channel and the uplink channels in the third uplink channel subset are all PUCCH, whether the uplink channels in the third uplink channel subset and the first uplink channel can be multiplexed is determined according to one of the above rules A1, A2, A3, B1, B2, C1 and C2.

[0133] Scenario S2: when the first uplink channel is PUCCH and all uplink channels in the third uplink channel subset are PUSCH, the tenth uplink channel is determined, and the first uplink channel and the tenth uplink channel are multiplexed according to the first rule in S420. Optionally, the tenth uplink channel is the uplink channel with the earliest starting time in the third uplink channel subset.

[0134] Scenario S3: When the first uplink channel is a PUCCH, and the third uplink channel subset includes both PUCCH and PUSCH, the UE determines a fourth uplink channel subset, which is a set of all PUCCHs in the third uplink channel subset, and determines whether the first uplink channel and the uplink channels in the fourth uplink channel subset can be multiplexed according to one of the above rules A1, A2, A3, B1, B2, C1 and C2.

[0135] Scenario S4: When the first uplink channel is a PUSCH, and all the uplink channels in the third uplink channel subset are PUCCHs, whether the first uplink channel and the uplink channels in the third uplink channel subset can be multiplexed is determined according to one of the above rules A1, A2, A3, B1, B2, C1 and C2.

[0136] Scenario S5: When the first uplink channel is a PUSCH, and all the uplink channels in the third uplink channel subset are PUSCHs, the UE expects that all the uplink channels in the third uplink channel subset have different priorities from the first uplink channel. If the first uplink channel has a higher priority, all the uplink channels in the third uplink channel subset are not transmitted (or discarded); if the first uplink channel has a lower priority, the first uplink channel is not transmitted (or discarded).

[0137] Scenario S6: When the first uplink channel is a PUSCH, and the third uplink channel subset includes both PUCCH and PUSCH, the UE determines a fourth uplink channel subset, which is a set of all PUCCHs in the third uplink channel subset, and determines whether the first uplink channel and the uplink channels in the fourth uplink channel subset can be multiplexed according to one of the above rules A1, A2, A3, B1, B2, C1 and C2.

[0138] Under the condition that the UE can multiplex and transmit the uplink channels in the third uplink channel subset and the first uplink channel, the UE multiplexes the uplink information carried on all the uplink channels in the third uplink channel subset and the uplink information carried in the first uplink channel on a sixth uplink channel and transmits to the base station. When the sixth uplink channel is neither the first uplink channel nor any uplink channel in the third uplink channel subset, the UE does not transmit all the uplink channels in the third uplink channel subset and the first uplink channel to the base station.

[0139] Under the condition that the UE determines that the uplink channels in the third subset of uplink channels and the first uplink channel cannot be multiplexed for transmission, the UE drops (i.e., does not transmit to the base station) all low-priority uplink channels in the third subset of uplink channels and the first uplink channel, or the UE drops (i.e., does not transmit to the base station) the earliest starting symbol uplink channel in all low-priority uplink channels in the third subset of uplink channels and the first uplink channel.

[0140] For multiplexing of the uplink channels in the first subset of uplink channels and the fourth subset of uplink channels, direct reference can be made to the multiplexing process of the uplink channels in the first subset of uplink channels and the third subset of uplink channels.

[0141] To meet the low-latency requirement of URLLC services, the UE can perform the above method at multiple time points within a time window to determine the transmission of the uplink channel as soon as possible. For example, for slot #n, the UE can perform the above method for the first time at time P1, where the distance between time P1 and the starting time of the slot #n is a first value; and then perform the above method for the second time at time P2, where the distance between time P2 and the middle position of the slot (corresponding to the starting time of symbol 7) is the first value. For the scenario where the UE performs the above method multiple times for a slot, when the above method is performed for the first time, the uplink channel determined by the UE in the above process is not actually transmitted, but only marked as to-be-transmitted as input for the next execution of the above method. When the UE performs the method for the last time, the uplink channel determined to be transmitted is actually transmitted.

[0142] For example, for slot #n, the UE can perform the above method for the first time at time Q1, where the distance between time Q1 and the starting time of the first uplink channel (i.e., the uplink channel with the earliest starting time) in the slot #n is a first value; and as the above method is performed for the first time, the set of uplink channels to be transmitted in the slot #n changes, when the starting time of the first uplink channel (denoted as the updated first uplink channel) in the slot #n increases, the UE can perform the above method for the second time at time Q2, where the distance between time Q2 and the starting time of the updated first uplink channel is the first value. For the scenario where the UE performs the above method multiple times for a slot, when the above method is performed for the first time, if the starting time of the above first uplink channel does not increase, the uplink channel determined by the UE in the above process is actually transmitted, and if the starting time of the above first uplink channel increases and there is an opportunity to perform the above process again, the uplink channel determined by the UE in the above process is not actually transmitted, but only marked as to-be-transmitted as input for the next execution of the above method.

[0143] It can be understood that the actions performed by the UE and the base station in the above method embodiments are corresponding, and the actions performed by the base station can be directly derived from the actions performed by the UE.

If the third subset of uplink channels is empty, transceiver unit 920 transmits the first uplink channel to the network device.
