In a first aspect, a method for multiplexing and transmitting uplink information is provided. The method can be performed by a terminal device or a module in the terminal device, or by a network device or a module in the network device. Taking the terminal device executing the method as an example, the method includes the following steps. The terminal device determines an uplink channel set that needs to perform uplink information multiplexing and transmission, the uplink channel set 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 uplink channel set, and the first uplink channel. The priority of the channel is the first priority, the first uplink channel is used to carry the first uplink information, and the second uplink channel is the uplink channel with the earliest start time among the uplink channels whose priority is the second priority in the uplink channel set. 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, and the first priority is 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. Satisfying the first condition with the second uplink channel and the first uplink channel may also be referred to as satisfying the timing relationship.

In a possible implementation manner of the first aspect, the terminal device determines the first uplink channel subset and the second uplink channel subset, and the uplink channel in the first uplink channel subset is the uplink channel set except the first uplink channel. In addition, the priority of the uplink channel in the first uplink channel subset is the same as that of the first uplink channel, and the uplink channel in the first uplink channel subset overlaps with the first uplink channel in the time domain. The uplink channels in the uplink channel subset and the first uplink channel satisfy the first condition; the uplink channels in the second uplink channel subset are uplink channels other than the second uplink channel in the uplink channel set, and the uplink channels in the second uplink channel subset The priority of the uplink channel is the same as the priority of the second uplink channel, the uplink channel in the second uplink channel subset overlaps with the second uplink channel in the time domain, and the uplink channel in the second uplink channel subset and the second uplink channel satisfy The first condition is that the uplink channels in the second uplink channel subset and the first uplink channel satisfy the first condition.

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

Thus, the transmission efficiency is improved.

In a second aspect, another method for multiplexing and transmitting uplink information is provided, and the method can be performed by a terminal device or a module in the terminal device, or by a network device or a module in the network device. Taking the terminal device executing the method as an example, the method includes the following steps.

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 determines the fifth uplink channel with the earliest start time in the third uplink channel subset. 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 uplink channel subset can be multiplexed with the first uplink channel one by one, the implementation can be simplified.

When the priorities of the fifth upstream channel and the first upstream channel are different, the fifth upstream channel and the first upstream channel are processed according to the first rule.

In a possible implementation manner of the second aspect, the first rule is at least one of the following rules: under 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 The network device sends the uplink channel E; under 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 fifth uplink channel and the first uplink channel to the network device with a higher priority Under the condition that the end symbol of the upstream channel E is not later than the end symbol of the upstream channel with higher priority in the fifth upstream channel and the first upstream channel, the terminal device sends the upstream channel E to the network device; Under the condition that the ending symbol of channel E is later than the ending symbol of the fifth upstream channel and the upstream channel with higher priority in the first upstream channel, the terminal device sends the fifth upstream channel and the first upstream channel with higher priority to the network device.

The terminal device determines a third uplink channel subset, and the uplink channels in the third uplink channel subset are uplink channels other than the first uplink channel in the uplink channel set that overlap with the first uplink channel in the time domain, and the third uplink channel The uplink channels in the uplink channel subset and the first uplink channel satisfy the first condition. 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 may also be called 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 perform multiplexing and how to perform multiplexing. By adopting this method, the number of judgments of the UE and the base station can be reduced.

The embodiments of the present application do not limit the application scenarios of the network device and the terminal device.

The network device and the terminal device can communicate through the frequency spectrum below 6 GHz (gigahertz, GHz), and can also communicate through the frequency spectrum above 6 GHz, and can also use the frequency spectrum below 6 GHz and the frequency spectrum above 6 GHz for communication at the same time. The embodiments of the present application do not limit the spectrum resources used between the network device and the terminal device.

Unless otherwise specified, the symbols in the embodiments of the present application all refer to time-domain symbols.

It can be understood that, in the embodiments of the present application, a physical downlink shared channel (PDSCH), a physical downlink control channel (PDCCH), and a physical uplink shared channel (PUSCH) The physical uplink control channel (PUCCH) is only an example of the downlink data channel, downlink control channel, uplink data channel and uplink control channel of the physical layer. In different systems and different scenarios, the data channel and control channels may have different names, which are not limited in the embodiments of the present application.

In the embodiment of the present application, the function of the network device may also be performed by a module (eg, a chip) in the network device, or may be performed by a control subsystem including the function of the base station. The control subsystem including the base station function here can be a control center in industrial IoT application scenarios such as smart grid, factory automation, and intelligent transportation. The functions of the terminal device may also be performed by a module (eg, a chip) in the terminal device.

For the convenience of description, the present application takes a base station as an example of a network device and a UE as an example of a terminal device for description. 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 has established a wireless connection is called the serving cell of the UE. When the UE communicates with the serving cell, it will also be interfered by signals from neighboring cells.

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

In order to improve the reliability of data transmission, the new radio (NR) of the 5G mobile communication system supports the hybrid automatic repeat request (HARQ) technology. For downlink data transmission, after the terminal device receives the data sent by the network device, if the decoding of the data is successful, it will feed back an acknowledgement (ACK) to the network device; if the decoding of the data fails, then Feedback a negative acknowledgement (NACK) to the network device. The ACK and NACK here may be collectively referred to as hybrid automatic repeat request acknowledgment (hybrid automatic repeat request-acknowledgment, HARQ-ACK) information. By adopting the HARQ technology, the retransmission data and the initial transmission data can be combined and decoded, which effectively improves the reliability of data transmission and the efficiency of data transmission.

Uplink information multiplexing and transmission is a common technology. The 3GPP version 15 (release 15, R15) protocol includes two application scenarios: (1) PUCCH#1 and PUCCH#2 overlap in the time domain. The uplink control information (UCI) carried by each PUCCH can be multiplexed to PUCCH#3 for transmission, where PUCCH#3 can be PUCCH#1 or PUCCH#2, or different from PUCCH#1 and PUCCH#3. Other PUCCHs of PUCCH#2; (2) PUCCH#1 and PUSCH#1 overlap in the time domain, and the UCI carried on PUCCH#1 can be multiplexed and transmitted on PUSCH#1 together with the data carried on PUSCH#1. In this embodiment of the present application, the overlap may include partial overlap and complete overlap, and partial overlap may also be understood as incomplete overlap. Unless otherwise specified, the overlapping in the embodiments of the present application all refer to overlapping in the time domain.

The main motivations for adopting this multiplexing transmission mechanism include: (1) Simultaneous transmission of two uplink channels that overlap in the time domain and are discontinuous in the frequency domain will increase the peak-to-average ratio of the transmitted signal, thereby increasing the power amplifier (power amplifier). The linear range of amplifier, PA) puts forward higher demands and increases the cost of PA; (2) If the time domain of the two uplink channels does not completely overlap, there will be a sudden change in the power of the two symbols before and after the overlapping junction, which will cause PA The phases of the s are discontinuous, so that the channel estimation on the symbols before the junction cannot be used for subsequent data demodulation.

The concept of physical layer priority is introduced in the 3GPP version 16 (release 16, R16) protocol, which can be used to indicate the priority of the information transmitted on the physical channel, and can also be understood to indicate that the information is URLLC The business is still eMBB business. In the embodiment of the present application, the physical layer priority may include low priority (low priority, LP) PUCCH and high priority (high priority, HP) two priorities.

Specifically, the priorities of information carried by different physical channels may be determined in the following manner.

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

The scheduling request (SR) is used by the UE to request uplink resources from the base station for uplink data transmission, and the beam failure recovery (BFR) is used by the UE to notify the base station of the deterioration of the current beam quality and trigger the beam recovery process. The priority of the SR carried in the PUCCH may be indicated by an 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.

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

For the data carried on the PUSCH, two scenarios are distinguished to determine its priority. For a PUSCH dynamically scheduled by DCI, also referred to as a grant-based (GB) PUSCH, the priority of the data carried on the GB PUSCH can be indicated by a priority indication field in the DCI. For a configured grant (configured grant, CG) PUSCH configured by RRC signaling, the priority of the data carried on the CG PUSCH can be indicated by configuring the information element in the RRC signaling of the CG.

In the embodiments of the present application, when the physical channel only carries information of one priority, the priority of the information can also be understood as the priority of the physical channel, the priority of the information and the physical channel that carries the information The priorities can be used interchangeably. There are the following four scenarios for multiplexing of uplink physical channels with 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, LP PUSCH and HP PUSCH reuse between. The embodiments of the present application focus on Scenario 1, Scenario 2, and Scenario 3. For these three scenarios, the UE can support multiplexing UCI carried on two PUCCHs on one PUCCH for transmission, or can support multiplexing UCI carried on one PUCCH and data carried on one PUSCH for transmission on this PUSCH.

After the 3GPP R16 protocol introduces the physical layer priority, for the two uplink physical channels of the same priority, you can refer to the rules defined in the R15 protocol for multiplexing transmission; for the two uplink physical channels of different priorities that overlap in the time domain, On the overlapping symbols, the UE only transmits the uplink physical channel of high priority, and cancels the transmission of uplink physical channel of low priority.

In a scenario where three uplink physical channels are multiplexed as shown in Figure 2, the UE will first process the LP PUCCH that overlaps in the time domain and the HP PUxCH scheduled by DCI#1 in the order of time, and the UE will discard the LP PUCCH information carried on the LP PUCCH, that is, the information carried on the LP PUCCH is not sent. Even if the 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 this application, PUxCH refers to PUCCH or PUSCH.

In another scenario where three uplink physical channels are multiplexed as shown in Figure 3, the UE will first process the LP PUxCH that overlaps in the time domain and the HP PUCCH scheduled by DCI#1 in the order of time, and the UE will discard the LP PUxCH. The information carried on the PUxCH, that is, the information carried on the LP PUxCH is not sent. Even if the HP PUxCH and HP PUCCH scheduled by DCI#2 overlap in the time domain later, the UE will multiplex the information transmitted on the HP PUCCH to the HP PUxCH for transmission so that the HP PUCCH is not actually sent, but the LP will not be resent. PUxCH.

In view of the deficiencies of the prior art in scenarios similar to those shown in FIG. 2 and FIG. 3 , the embodiment of the present application provides a multiplexing method for multiple uplink physical channels with different priorities, so as to avoid discarding uplink information to be transmitted as much as possible. Improve the utilization and transmission efficiency of uplink physical channels. For multiplexing of multiple uplink physical channels with different priorities, the general principle is to process the multiplexing of uplink physical channels of the same priority first, and then process the multiplexing of uplink physical channels of different priorities.

The flow is described in detail below. This process can be performed on the base station and the UE side respectively.

The uplink channel, 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, and the first priority is different from the second priority.

Specifically, the base station and the UE may determine the uplink channel set in one time slot, that is, the uplink channels to be sent in the same time slot constitute the uplink channel set. If there are multiple upstream channels with the same start time and the upstream channel with the earliest start time in the upstream channel set, one of the upstream channels with the earliest start time can be selected as the first upstream channel. The specific selection rules It can be at least one of the following rules: randomly select one; select the uplink channel with the longest time domain length; or select the PUCCH bearing HARQ-ACK.

When both the first uplink channel subset and the second uplink channel subset are 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.

Specifically, when the third uplink channel is neither an uplink channel in the first uplink channel subset nor the first uplink channel, the UE may not send the uplink channel and the first uplink channel in the first uplink channel subset to the base station, Correspondingly, the base station does not receive the uplink channel and the first uplink channel in the first uplink channel subset. That is to say, the time-frequency resources of the third uplink channel determined in S413a or S413c are different from the time-frequency resources of the uplink channels in the first uplink channel subset, and are also different from the time-frequency resources of the first uplink channel. At this time, the information originally carried in the uplink channels in the first uplink channel subset and the information originally carried in the first uplink channel are both carried on the newly determined third uplink channel. Neither the uplink channel nor the first uplink channel in the original first uplink channel subset is sent anymore. The time-frequency resources of the third uplink channel may be determined according to the number of bits of information carried on the third uplink channel and related configuration parameters. Of course, the third uplink channel may also be a certain uplink channel in the first uplink channel subset, or may be the first uplink channel. At this time, in the uplink channel and the first uplink channel in the first uplink channel subset, the UE The other uplink channels other than the third uplink channel are not sent to the base station.

Similarly, when the fourth uplink channel is neither an uplink channel in the second uplink channel subset nor a second uplink channel, the UE may not send the uplink channel and the second uplink channel in the second uplink channel subset to the base station. That is to say, the time-frequency resources of the fourth uplink channel determined in S413b or S413c are different from the time-frequency resources of the uplink channels in the second uplink channel subset, and are also different from the time-frequency resources of the second uplink channel. Of course, the fourth uplink channel may also be a certain uplink channel in the second uplink channel subset, or may be the second uplink channel. At this time, in the uplink channel and the second uplink channel in the second uplink channel subset, the UE No other uplink channels except the fourth uplink channel are sent to the base station.

The following is an example of determining the third uplink channel, and further describes the process of determining the uplink channel used for carrying uplink information after multiplexing in the multiplexing process of multiple uplink channels with the same priority in S413a, S413b and S413c. The method for determining the fourth uplink channel is the same as the method for determining the third uplink channel.

In scenario a, under the condition that both the first uplink channel and the uplink channels in the first uplink channel subset are PUCCH, the third uplink channel determined by the base station and the UE is also PUCCH. The time-frequency resource of the third uplink channel may be the same as or different from the time-frequency resource of any one of the first uplink channel and the uplink channels of the first uplink channel subset.

Scenario b, under the condition that the first uplink channel is PUCCH and all 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 upstream information in the third upstream channel. Optionally, the third uplink channel is the uplink channel with the earliest start time in the first uplink channel subset.

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 first uplink channel sub-set Uplink information carried by all PUCCHs in the set.

Optionally, when the third uplink channel overlaps with one or more PUSCHs in the first uplink channel subset in the time domain, the base station and the UE may also determine that the eighth uplink channel is used to carry the uplink information carried on the third uplink channel. and the uplink information carried in the eighth uplink channel, where the eighth uplink channel is the PUSCH with the earliest start time in the PUSCH overlapping with the third uplink channel. And take the eighth upstream channel as the third upstream channel in S413a and S413c.

Scenario d, under 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 UE use the first uplink channel as the third uplink channel to carry the first uplink information and uplink information carried by the uplink channels in the first uplink channel subset. Alternatively, when multiple PUCCHs in the first uplink channel subset overlap, the base station and the UE determine that the ninth uplink channel is used to carry 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 to carry the first uplink information and the uplink information carried by the ninth uplink channel. And use the first upstream channel as the third upstream channel in S413a and S413c.

In scenario e, under 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.

Scenario f, when the first uplink channel is PUSCH, and the first uplink channel subset includes both PUCCH and PUSCH, the base station and the UE determine to use the first uplink channel to carry the first uplink information and the first uplink channel. The uplink information carried by the PUCCH in the subset. Alternatively, under the condition that multiple PUCCHs in the first uplink channel subset overlap, the base station and the UE determine that the ninth uplink channel is used to carry the uplink information carried by the PUCCHs 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 to carry the first uplink information and the uplink information carried by the ninth uplink channel. And use the first upstream channel as the third upstream channel in S413a and S413c.

The first condition mentioned in S410 is specifically described below. The uplink channel A and the uplink channel B satisfy the first condition, which specifically includes: under the condition that one of the uplink channel A and the uplink channel B is a PUCCH, and the PUCCH is used to carry the HARQ-ACK information for the HARQ-ACK information, refer to The distance between the symbol and the end symbol of the first physical downlink shared channel PDSCH is greater than or equal to the first threshold, where the reference symbol is the start symbol of the uplink channel A and the start symbol of the uplink channel B with an earlier start time. symbol, the first PDSCH is the PDSCH corresponding to the HARQ-ACK information, and the value of the first threshold is the same as the subcarrier spacing of the first PDSCH, the time domain length of the first PDSCH, the mapping type of the first PDSCH, and the UE capability. At least one correlation; under the condition that one of the uplink channel A and the uplink channel B is a PUSCH, the distance between the reference symbol and the end symbol of the first PDCCH is greater than or equal to the second threshold, wherein the first PDCCH is related to the For the PDCCH corresponding to the PUSCH, the value of the second threshold is related to at least one of the subcarrier spacing of the PUSCH, the mapping type of the PUSCH, and the UE capability. The uplink channel A and the uplink channel B here are the uplink channels in the uplink channel set. Specifically, the HARQ-ACK information is the ACK/NACK information of the data carried in the first PDSCH. When the above-mentioned PUSCH is a GB PUSCH, the DCI in the first PDCCH is used to schedule the GB PUSCH; when the above-mentioned PUSCH is a type 2 (type-2) CG PUSCH, the DCI in the first PDCCH is used to activate the CG PUSCH.

The above-mentioned first threshold T ₁ =N ₁ +d _1,1 +1 symbols, the value of N ₁ is related to at least one of the subcarrier spacing of the first PDSCH and the UE capability, and the value of d _1,1 is related to the The time domain length of the first PDSCH is related to at least one of the mapping types of the first PDSCH, and N ₁ and d _1,1 are integers greater than or equal to zero. N ₁ +d _1,1 is used to ensure that the UE has enough time to generate HARQ-ACK and complete transmission preparation after receiving the PDSCH. The extra 1 symbol is a processing delay specially introduced for multiple channel multiplexing.

The above-mentioned second threshold T ₂ =N ₂ +d _2,1 +1, where the value of N ₂ is related to at least one of the subcarrier spacing of the PUSCH and the capability of the UE, and the value of d _2,1 is related to the PUSCH The mapping type is related. N ₂ +d _2,1 is used to ensure that the UE has enough time to complete the transmission preparation of the PUSCH after receiving the DCI, and the extra 1 symbol is a processing delay specially introduced for multiple channel multiplexing.

The first condition here can also be understood as a timing condition for whether multiple uplink channels can be multiplexed. For the multiplexing of PUCCH and PUCCH, it is mainly considered whether the multiplexed PUCCH can meet the timing requirement for feeding back HARQ-ACK information. If all PUCCHs do not carry HARQ-ACK information, but only carry SR or CSI, it is considered that the timing condition is not required, that is, the first condition is satisfied by default. For the multiplexing of PUCCH and PUSCH, in addition to whether the multiplexed PUSCH used for transmission can meet the timing requirements of the PUSCH itself, it is also necessary to consider whether the timing requirements of the HARQ-ACK information can be met.

The uplink information multiplexing and transmission in the above S420, S420a, S420b and S420c will be described in detail below. Multiplexing and transmitting the uplink information carried in the uplink channel C and the uplink channel D, including: processing the uplink channel C and the uplink channel D according to the first rule under the condition that the uplink channel C and the uplink channel D overlap in the time domain; And/or, under the condition that the uplink channel C and the uplink channel D do not overlap in the time domain, the uplink channel C and the uplink channel D are sent. The upstream channel C is the first upstream channel or the third upstream channel, and the upstream channel D is the second upstream channel or the fourth upstream channel. In the embodiment of the present application, multiplexing or multiplexing transmission of two uplink channels may also be referred to as multiplexing the uplink information carried in the two uplink channels to one of the two uplink channels for transmission, Or multiplex to other uplink channels for transmission.

The above-mentioned 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 may be one of rules 1a, 1b, 1c, 1d, 1e, and 1f; the first rule may also be a combination of two of rules 1a, 1c, and 1e, or rules 1b, 1d, and 1e. A combination of two of 1f; the first rule can also be a combination of three of rules 1a, 1c, and 1e, or a combination of three of rules 1b, 1d, and 1f. The first rule here is to determine whether physical channels with different priorities can be multiplexed and transmitted. Multiplexing with different priorities may lead to increased HP PUCCH transmission delay or reduced reliability. Whether multiplexing transmission with different priorities can be performed can be indicated by the base station to the UE through signaling, or it can be judged by whether the multiplexing will increase the transmission delay or reduce the reliability of high-priority information. In the embodiments of the present application, unless otherwise specified, the signaling may be RRC signaling, medium access control (MAC) signaling, or physical layer signaling (for example, DCI) . The higher layer signaling can be RRC signaling or MAC signaling.

Rule 1a, under the condition that the first indication information indicates that the uplink channel C and the uplink channel D can be multiplexed, the UE sends the uplink channel E to the base station, and the UE does not send the uplink channel C and the uplink channel D to the base station. The first indication information here may be carried in the signaling and sent by the base station to the UE to indicate whether the uplink channel (uplink channel C or uplink channel D) can be multiplexed and transmitted with other priority uplink channels, or It is understood that it is used to indicate whether the uplink information carried in the uplink channel (the uplink channel C or the uplink channel D) can be multiplexed and transmitted with the uplink information of other priorities.

Rule 1b, under the condition that the first indication information indicates that the uplink channel C and the uplink channel D cannot be multiplexed, the UE may send the uplink channel C and the uplink channel D with the higher priority to the base station, and the UE may not send the uplink channel to the base station. The uplink information carried by the uplink channel with lower priority in the uplink channel C and the uplink channel D and the uplink channel with the lower priority in the uplink channel C and the uplink channel D is sent.

Rule 1c, the UE sends the uplink channel E to the base station under the condition that the end symbol of the uplink channel E is not later than the end symbol of the uplink channel with a higher priority in the uplink channel C and the uplink channel D. The UE does not send the uplink channel C and the uplink channel D to the base station.

Rule 1d, under the condition that the end symbol of the uplink channel E is later than the end symbol of the uplink channel C and the uplink channel D with higher priority, the UE can send the uplink channel C and the uplink channel D to the base station. For the uplink channel with higher priority, the UE does not send the uplink information carried by the uplink channel with lower priority in uplink channel C and uplink channel D and the uplink channel with lower priority in uplink channel C and uplink channel D to the base station.

Rule 1e, the UE sends the uplink channel E to the base station under the condition that the encoding code rate of the uplink channel E is not greater than the encoding code rate of the uplink channel with higher priority among the uplink channel C and the uplink channel D. The UE does not send the uplink channel C and the uplink channel D to the base station. Wherein, under the condition that the uplink information of different priorities is independently encoded, the encoding code rate of the uplink channel E may be the encoding code rate of the high-priority uplink information in the uplink channel E.

Rule 1f, under the condition that the encoding code rate of uplink channel E is greater than the encoding code rate of uplink channel C and uplink channel D with higher priority, the UE can send the priority of uplink channel C and uplink channel D to the base station. For the higher uplink channel, the UE does not send the uplink information carried by the uplink channel with lower priority in uplink channel C and uplink channel D and the uplink channel with lower priority in uplink channel C and uplink channel D to the base station.

The above-mentioned uplink channel E is an uplink channel determined by the UE for carrying the uplink information carried in the uplink channel C and the uplink channel D. The time-frequency resources of the uplink channel E may be the same as the time-frequency resources of the uplink channel C or the uplink channel D, or may be partially the same or completely different from the time-frequency resources of the uplink channel C or the uplink channel D.

The following takes the combination of rule 1a and rule 1c as an example to illustrate the combination of the above-mentioned rules. The combination of rule 1a and rule 1c: the first indication information indicates that uplink channel C and uplink channel D can be multiplexed, and the end symbol of uplink channel E is no later than the uplink channel with higher priority in uplink channel C and uplink channel D. Under the condition of the end symbol of , 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.

In the embodiments of the present application, the uplink channels in the uplink channel set are all physical channels, such as 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 cell in the RRC signaling configuring the first uplink channel, and the second priority is the first priority corresponding to the second uplink channel. The second is indicated by the field in the DCI or indicated by the information element in the RRC signaling configuring the second uplink channel. Specifically, for the method for determining the first priority and the second priority, reference may be made to the aforementioned method for determining the priority of the information carried by the physical channel.

FIG. 6 provides another possible implementation manner of the embodiments in FIGS. 4 and 5 provided by the embodiments of the present application. For detailed descriptions of S601 to S615 in FIG. 6 , reference may be made directly to the related descriptions of FIG. 4 and FIG. 5 above. It can be understood that the numbering sequence in FIG. 6 does not limit the code execution sequence when the actual product is implemented. For example, S603 and S604 can be executed after S605, or can be executed after S606, S607 or S612.

Through the uplink channel multiplexing method provided in the above Figure 4, Figure 5 and Figure 6, the uplink channels with the same priority are multiplexed first, and then two uplink channels with different priorities are multiplexed to avoid some Content carried in low-priority upstream channels is discarded, thereby improving transmission efficiency.

FIG. 7 is a schematic flowchart of another method for multiplexing and transmitting multiple uplink physical channels with different priorities according to an embodiment of the present application. This process can be performed on the base station and the UE side respectively.

S701, the base station and the UE determine an uplink channel set that needs to perform uplink information multiplexing and transmission.

S702, the base station and the UE determine the first uplink channel with the earliest start time in the uplink channel set.

For the specific processes of S701 and S702, reference may be made to the relevant description in S410.

S703, the base station and the UE determine the third uplink channel subset subset#3. The uplink channels in the third uplink channel subset are uplink channels other than the first uplink channel in the uplink channel set that overlap with the first uplink channel in the time domain, and the uplink channels in the third uplink channel subset are the same as the first uplink channel. The upstream channel satisfies the first condition. For a detailed description of the first condition, reference may be made to the description of the first condition in the embodiment shown in FIG. 4 . The priority of the uplink channels in the third uplink channel subset may be the same as the priority of the first uplink channel, or may be different from the priority of the first uplink channel.

S704, the base station and the UE determine whether the third uplink channel subset is an empty set.

S705, in the case that the third uplink channel subset is an empty set, the UE sends the first uplink channel to the base station.

S706, in the case that the third uplink channel subset is not an empty set, the base station and the UE determine the fifth uplink channel with the earliest start time in the third uplink channel subset.

If there are multiple uplink channels in the third uplink channel subset with the same start time and the upstream channel with the earliest start time in the third uplink channel subset, one of the uplink channels with the earliest start time can be selected as the For the fifth uplink channel, the specific selection rule may be at least one of the following rules: randomly select one; select the longest time domain length; or select the uplink channel with the same priority as the first uplink channel.

S707, the base station and the UE multiplex and transmit the fifth uplink channel and the first uplink channel, that is, multiplex and transmit the information carried in the fifth uplink channel and the first uplink channel.

In the case where the priorities of the fifth uplink channel and the first uplink channel are the same, a sixth uplink channel is determined, and the sixth uplink channel is used to carry the uplink information carried in the fifth uplink channel and the first uplink channel. When the sixth uplink channel is neither the first uplink channel nor the fifth uplink channel, the UE does not send 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.

When the priorities of the fifth upstream channel and the first upstream channel are different, the fifth upstream channel and the first upstream channel are processed according to the first rule. For the specific description of the first rule, reference may be made to the related description of the first rule in the embodiment of FIG. 4 .

After the execution of S707 is completed, the sixth uplink channel is used as the uplink channel to be sent, and the base station and the UE continue to perform S702.

The embodiment of FIG. 7 provides a method for judging whether multiplexing is performed one by one, which can simplify the implementation.

The above S706 and S707 may also be replaced by S806 in FIG. 8 .

S806, multiplexing the uplink channel and the first uplink channel in the third uplink channel subset. This multiplexing manner may also be called 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 perform multiplexing and how to perform multiplexing. By adopting this method, the number of judgments of the UE and the base station can be reduced.

In the case where the priorities of all the uplink channels in the third uplink channel subset are the same as the priorities of the first uplink channels, determine a sixth uplink channel for carrying the uplink information carried by all the uplink channels in the third uplink channel subset and Uplink information carried in 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 the uplink channels and the first uplink channel in the third uplink channel subset to the base station. In the embodiments of the present application, the UE does not transmit a certain uplink channel, which may also be referred to as the UE discarding a certain uplink channel.

In the case that the priority of at least one uplink channel in the third uplink channel subset is different from that of the first uplink channel, the base station and the UE according to rule A1, rule A2, rule A3, rule B1, rule B2, rule C1 and at least one of the rules C2 to determine whether all the uplink channels in the third uplink channel subset can be multiplexed with the first uplink channel. For example, it can be determined according to one of the rules A1, A2, A3, B1, B2, C1, and C2; or, it can also be determined according to at least two of the rules A1, B1, and C1, or it can be determined according to the rules A1, B1, and C1. At least two of B2 and C2; alternatively, it can be determined according to at least two of A2, B1 and C1, and it can also be determined according to at least two of A2, B2 and C2; or, it can be determined according to the rules It is determined by at least two items of A3, B1 and C1, and it can also be determined according to at least two items of rules A3, B2 and C2.

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

Scenario A1-1, if only one of the uplink channel in the third uplink channel subset and the first uplink channel is scheduled or triggered by DCI, the UE determines whether the third uplink channel can be processed according to the value of the first field in the DCI. The uplink channel of the channel subset and the first uplink channel are multiplexed and transmitted.

Scenario A1-2, if there are multiple uplink channels in the third uplink channel subset and the first uplink channel that are scheduled or triggered by DCI, the UE can determine whether or not to select the third uplink channel according to at least one of the following rules: The uplink channels of the subset and the first uplink channel are multiplexed and transmitted.

Rule A1-2a, select a DCI from the above-mentioned multiple DCIs that schedule or trigger the uplink channel, and determine whether the uplink channel and the first uplink channel of the third uplink channel subset can be determined according to the value of the first field in the DCI. multiplex transmission. The DCI can be selected according to at least one of the following selection strategies: the DCI corresponding to the uplink channel with high priority is preferentially selected; the DCI with the later time domain position is preferentially selected. The time domain position here may be the start symbol position or the end symbol position of the PDCCH carrying the DCI.

Rule A1-2b, if and only if the values of the first fields in the above-mentioned multiple DCIs all indicate that they can be multiplexed with uplink channels of other priorities, the UE can determine that the uplink channels and the third uplink channel subsets can be used for the third uplink channel subset. An uplink channel is used for multiplexing transmission.

Rule A1-2c, if and only if the value of the first field in the DCI corresponding to all high-priority uplink channels indicates that it can be multiplexed with other priority uplink channels, the UE can determine that the third uplink channel can be used for The uplink channels of the subset and the first uplink channel are multiplexed and transmitted.

Scenario A1-3, if all the uplink channels and the first uplink channel in the third uplink channel subset are configured by high-level signaling, then according to the indication information in all the high-level signaling configuring these uplink channels (for example, the first The value of element) determines whether the uplink channel of the third uplink channel subset and the first uplink channel can be multiplexed for transmission. Specifically, the UE may determine whether to multiplex and transmit the uplink channel of the third uplink channel subset and the first uplink channel according to one of the following rules.

Rule A1-3a, when the value of the first information element in all high-level signaling configuring these uplink channels indicates that it can be multiplexed with other priority uplink channels, the UE determines that the third uplink channel subset can be used for multiplexing. The uplink channel and the first uplink channel are multiplexed and transmitted.

Rule A1-3b, when the value of the first information element in the high-level signaling configuring all high-priority uplink channels indicates that it can be multiplexed with uplink channels of other priorities, the UE determines that the third uplink channel can be used for multiplexing. The uplink channels of the subset and the first uplink channel are multiplexed and transmitted.

Rule A2, for each uplink channel, the base station sends a signaling to the UE to indicate whether it can be multiplexed with other priority uplink channels. The UE preferentially determines whether all the uplink channels in the third uplink channel subset and the first uplink channel can be multiplexed according to the indication information corresponding to the high-priority uplink channel. Specifically, it can be subdivided into three scenarios for description.

Scenario A2-1, if only one of the uplink channel in the third uplink channel subset and the high-priority uplink channel in the first uplink channel is scheduled or triggered by DCI, the UE determines according to the value of the first field in the DCI Whether the uplink channel of the third uplink channel subset and the first uplink channel can be multiplexed and transmitted.

Scenario A2-2, if the uplink channel in the third uplink channel subset and the high-priority uplink channel in the first uplink channel have multiple uplink channels that are scheduled or triggered by DCI, the UE can determine according to at least one of the following rules Whether to multiplex and transmit the uplink channel of the third uplink channel subset and the first uplink channel.

Rule A2-2a, select the DCI with the earliest time domain position, and determine whether to multiplex and transmit the uplink channel of the third uplink channel subset and the first uplink channel according to the value of the first field in the DCI. The time domain position here may be the start symbol position or the end symbol position of the PDCCH carrying the DCI.

Rule A2-2b, when the value of the first field in the DCI corresponding to all high-priority uplink channels indicates that it can be multiplexed with other priority uplink channels, then determine the uplink channel and the third uplink channel subset. The first uplink channel performs multiplexing transmission.

Scenario A2-3, if both the uplink channels in the third uplink channel subset and the high-priority uplink channels in the first uplink channel are configured by high-level signaling, then according to all the high-priority uplink channels configured in the high-level signaling The value of the indication information (for example, the first cell) of , determines whether the uplink channel of the third uplink channel subset and the first uplink channel can be multiplexed for transmission. When the value of the first information element in the high-level signaling configuring these high-priority uplink channels indicates that the uplink channels of other priorities can be multiplexed, the UE determines that the uplink channels of the third uplink channel subset can be used for multiplexing. Multiplex transmission with the first uplink channel. When one of the values of the first information element in the high-level signaling configuring these high-priority uplink channels indicates that it cannot be multiplexed with uplink channels of other priorities, the UE determines not to use the third uplink channel subset. The uplink channel and the first uplink channel are multiplexed and transmitted.

Rule A3, for each uplink channel, the base station sends a signaling to the UE to indicate whether it can be multiplexed with other priority uplink channels. The UE determines whether all the uplink channels in the third uplink channel subset and the first uplink channel can be multiplexed according to the indication information corresponding to all the uplink channels included in the first uplink channel and the third uplink channel subset. The indication information here may be the first field in the DCI, or may be the first information element in the higher layer signaling. Specifically, when the values of the indication information corresponding to all the uplink channels included in the first uplink channel and the third uplink channel subset indicate that they can be multiplexed with uplink channels of other priorities, the UE determines that the third uplink channel can be used for multiplexing. The uplink channels of the subset and the first uplink channel are multiplexed and transmitted. When one of the values of the indication information corresponding to all the uplink channels included in the first uplink channel and the third uplink channel subset indicates that it cannot be multiplexed with uplink channels of other priorities, the UE determines not to use the third uplink channel subset. The upstream channel of the set and the first upstream channel are multiplexed and transmitted.

Rule B1, in the case where the end symbol of the sixth uplink channel is not later than the end symbol 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 respond to the third uplink channel. The uplink channel of the channel subset and the first uplink channel are multiplexed and transmitted.

Rule B2, when the end symbol of the sixth uplink channel is later than the end symbol of the seventh uplink channel, it is determined that the UE cannot multiplex and transmit the uplink channel of the third uplink channel subset and the first uplink channel. The seventh uplink channel here is an uplink channel in the third uplink channel subset and a certain uplink channel with a high priority in the first uplink channel.

Rule C1, under 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 The uplink channel of the uplink channel subset and the first uplink channel are multiplexed and transmitted. Wherein, under the condition that the uplink information of different priorities is independently encoded, the encoding code rate of the sixth uplink channel may be the encoding code rate of the high-priority uplink information in the sixth uplink channel.

Rule C2, under the condition that the encoding code rate of the sixth uplink channel is greater than the encoding code rate of the seventh uplink channel, it is determined that the UE cannot multiplex and transmit the uplink channel of the third uplink channel subset and the first uplink channel.

The above-mentioned sixth uplink channel is an uplink channel determined by the UE to carry the uplink information carried by all the uplink channels in the third uplink channel subset and the uplink information carried in the first uplink channel.

The following takes the combination of rules B1 and C1 as an example to illustrate the combination of the above rules. The combination of rule B1 and rule C1: the end symbol of the sixth upstream channel is no later than the end symbol of all upstream channels in the third upstream channel subset and all high-priority upstream channels in the first upstream channel, and the sixth upstream channel Under the condition that the coding rate 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 The first uplink channel performs multiplexing transmission.

The base station and the UE can determine which uplink channels are to be multiplexed and transmitted according to the channel types of the uplink channels in the first uplink channel and the third uplink channel subset (the channel types here include PUCCH and PUSCH). The above S806 is further described.

Scenario S1: When the uplink channels in the first uplink channel and the third uplink channel subset are both PUCCH, determine whether the The uplink channel in the subset of the three uplink channels is multiplexed with the first uplink channel.

Scenario S2: When the first uplink channel is PUCCH, and all uplink channels in the third uplink channel subset are PUSCH, determine the tenth uplink channel, and perform the first uplink channel and the tenth uplink channel according to the first rule in S420. Reuse processing. Optionally, the tenth uplink channel is the uplink channel with the earliest start time in the third uplink channel subset.

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

Scenario S4: When the first uplink channel is PUSCH, and all uplink channels in the third uplink channel subset are PUCCH, determine whether the Multiplexing the uplink channels in the first uplink channel and the third uplink channel subset.

Scenario S5: When the first uplink channel is PUSCH and all uplink channels in the third uplink channel subset are PUSCH, the UE expects that all uplink channels in the third uplink channel subset have different priorities from the first uplink channel. If the priority of the first uplink channel is high, all uplink channels in the third uplink channel subset are not sent (or discarded); if the priority of the first uplink channel is low, the first uplink channel is not sent (or discarded).

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

Under the condition that it is determined that the UE can multiplex and transmit the uplink channels of the third uplink channel subset and the first uplink channels, the UE transmits 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 The uplink information is multiplexed and sent to the base station on the sixth uplink channel. 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 the uplink channels and the first uplink channel in the third uplink channel subset to the base station.

Under the condition that the UE cannot multiplex and transmit the uplink channel of the third uplink channel subset and the first uplink channel, the UE discards (ie does not send to the base station) the uplink channel and the first uplink channel of the third uplink channel subset All low-priority uplink channels, or the UE discards (that is, does not send to the base station) the uplink channel of the third uplink channel subset and the uplink channel with the earliest start symbol among all low-priority uplink channels in the first uplink channel .

The multiplexing of the uplink channels in the first uplink channel and the fourth uplink channel subset can be obtained directly by referring to the above-mentioned multiplexing process of the uplink channels in the first uplink channel and the third uplink channel subset.

In order to meet the low latency requirement of the URLLC service, the UE may execute the above method at multiple time points within a time window, so as to determine the transmission of the uplink channel as early as possible. For example, for time slot #n, the UE may perform the above method for the first time at time P1, wherein the distance between time P1 and the start time of this time slot #n is the first value; and then perform the above method for the second time at time P2 , the distance between time P2 and the middle position of the time slot (corresponding to the start time of symbol 7) is the first value. For a scenario where the UE performs the above method multiple times on a time slot, when the above method is executed for the first time, the UE determines that the uplink channel sent in the above process is not actually sent, but only marks the uplink channel as to be sent. as input for the next execution of the above method. When the UE executes this method for the last time, the uplink channel determined to be sent will be actually sent out. Correspondingly, when the base station executes the method for the last time in the time slot, it is determined that the received uplink channel is actually received.

For another example, for time slot #n, the UE may perform the above method for the first time at time Q1, wherein time Q1 and the start time of the first uplink channel in this time slot #n (that is, the uplink channel with the earliest start time) The distance is the first value; as the above method is performed for the first time, the set of uplink channels to be sent in time slot #n changes, and the first uplink channel in time slot #n (recorded as the first uplink channel after the update After the starting time of the updated channel) is increased, the UE may perform the above method a second time at time Q2, wherein the distance between time Q2 and the starting time of the first uplink channel after updating is the first value. For a scenario where the UE executes the above method multiple times in a time slot, when the above method is executed for the first time, if the start time of the above-mentioned first uplink channel does not increase, the UE determines the transmitted uplink channel in the above-mentioned process. It is a real transmission. If the start time of the first uplink channel increases and there is an opportunity to perform the above process again, the UE determines that the transmitted uplink channel is not a real transmission in the above process, but only marks the uplink channel as pending. Send as input for the next execution of the above method.
