[0116] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0117] Figure 1 This is a schematic diagram of an application scenario according to an embodiment of this application.

[0118] like Figure 1 As shown, the communication system 100 may include a terminal device 110 and a network device 120. The network device 120 can communicate with the terminal device 110 via an air interface. Multi-service transmission is supported between the terminal device 110 and the network device 120.

[0119] It should be understood that the embodiments of the present invention are only illustrated by way of example with communication system 100, but the embodiments of the present invention are not limited thereto. That is to say, the technical solutions of the embodiments of the present invention can be applied to various communication systems, such as: Global System for Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD) system, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system, New Radio (NR) or future 5G systems, etc.

[0120] Taking 5G systems as an example, the technical solutions of this application can be applied to wide-area Long Term Evolution (LTE) coverage and NR island coverage modes. Furthermore, a large number of LTE deployments are below 6 GHz, leaving very little spectrum available for 5G below 6 GHz. Therefore, NR must explore spectrum applications above 6 GHz, but high-frequency band coverage is limited and signal fading is rapid. Simultaneously, to protect mobile operators' initial investments in LTE, a tight interworking mode between LTE and NR is proposed.

[0121] The main application scenarios of 5G include: Enhanced Mobile Broadband (eMBB), Ultra-Reliable and Low-Latency Communication (URLLC), and Massive Machine-Type Communication (mMTC). Among these, eMBB, which aims to provide users with multimedia content, services, and data, is experiencing rapid demand growth. Since eMBB may be deployed in different scenarios—for example, indoors, urban areas, and rural areas—its capabilities and needs vary significantly, so generalizations are not possible; a detailed analysis based on the specific deployment scenario is necessary. Typical applications of URLLC include: industrial automation, power automation, remote medical operations (surgery), and traffic safety assurance. Typical characteristics of mMTC include: high connection density, small data volume, latency-insensitive services, low module cost, and long module lifespan.

[0122] exist Figure 1 In the communication system 100 shown, network device 120 may be an access network device that communicates with terminal device 110. The access network device can provide communication coverage for a specific geographical area and can communicate with terminal device 110 (e.g., UE) located within that coverage area.

[0123] For example, the access network equipment can be a base station (BTS) in a Global System of Mobile communication (GSM) system or a code division multiple access (CDMA) system, a base station (NodeB, NB) in a wideband code division multiple access (WCDMA) system, or an evolved Node B (eNB or eNodeB) in a long term evolution (LTE) system.

[0124] Optionally, the access network device can also be a Next Generation Radio Access Network (NG RAN), a base station (gNB) in an NR system, a radio controller in a Cloud Radio Access Network (CRAN), or a relay station, access point, vehicle-mounted equipment, wearable device, or network equipment in a future evolved Public Land Mobile Network (PLMN).

[0125] The terminal device 110 can be any terminal device. It can communicate with one or more core networks via a Radio Access Network (RAN). It can also be referred to as an access terminal, User Equipment (UE), User Unit, User Station, Mobile Station, Mobile Station, Remote Station, Remote Terminal, Mobile Device, User Terminal, Terminal, Wireless Communication Equipment, User Agent, or User Equipment. For example, it can be a cellular phone, cordless phone, Session Initiation Protocol (SIP) phone, Wireless Local Loop (WLL) station, Personal Digital Assistant (PDA), handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, in-vehicle equipment, wearable device, and terminal equipment in a 5G network, etc.

[0126] It should be understood that the terms "system" and "network" are often used interchangeably in this article.

[0129] S210, the terminal device determines multiple uplink channels / signals transmitted within the target time unit, which at least partially overlap in the time domain.

[0130] S220, the network device identifies the multiple uplink channels / signals.

[0131] S230, when the multiple uplink channels / signals meet the constraints, the terminal device multiplexes the information carried in the multiple uplink channels / signals into one channel / signal within the target time unit for transmission.

[0132] The constraint includes the following: the first symbol of the earliest uplink channel / signal among the plurality of uplink channels / signals is not earlier than the Ath symbol after the start time or the last symbol of the target channel / signal, where A is a non-negative integer.

[0133] The target time unit in this embodiment of the invention can be understood as the resource granularity of time-domain resources, such as, but not limited to: time slots, subframes, frames, and transmission time units, etc.

[0134] Optionally, A = N2 + 1, where N2 is the preparation time for PUSCH.

[0135] Optionally, A = N2 + d2,1, where N2 is the preparation time for PUSCH.

[0136] Optionally, the value of d2,1 is related to the structure of the demodulation reference signal (DMRS) in the PUSCH. For example, d2,1 = 0 if only the first time-domain symbol in the PUSCH includes DMRS; otherwise, d2,1 = 1.

[0137] Optionally, the constraint also includes: the start time of the earliest uplink channel / signal among the plurality of uplink channels / signals is no earlier than the Bth symbol after the last symbol of the target channel / signal, where B is a non-negative integer.

[0138] Optionally, B = N2 + d1,1 + d1,2, where N1 is the processing time of PDSCH.

[0139] Optionally, B = N1 + 1 + d1,2, where N1 is the processing time of the Physical Downlink Shared Channel (PDSCH).

[0140] Optionally, the value of d1,1 depends on the corresponding ACK / NACK transmission method. For example, when using PUCCH to transmit the corresponding ACK / NACK, d1,1 = 0; when using PUSCH to transmit the corresponding ACK / NACK, d1,1 = 1.

[0141] Optionally, the values ​​of d1,2 are related to the PDSCH mapping method. For example, if the PDSCH mapping method is mapping type A as specified in Section 7.4.1.1 of 3GPP Technical Specification (TS) 38.211, and the last symbol of the PDSCH is on the i-th symbol in a slot less than 7, then d1,2 = 7 - i. As another example, if the PDSCH mapping method is mapping type B as specified in Section 7.4.1.1 of 3GPP Technical Specification (TS) 38.211, and the number of allocated PDSCH symbols is 4, then d1,2 = 3. As yet another example, if the PDSCH mapping method is mapping type B as specified in Section 7.4.1.1 of 3GPP Technical Specification (TS) 38.211, and the number of allocated PDSCH symbols is 2, then d1,2 = 3 + d, where d is the number of overlapping symbols between the scheduling PDCCH and the allocated PDSCH. For example, if the PDSCH mapping method is neither mapping type A nor mapping type B mentioned above, then d1,2 = 0.

[0142] Optionally, each of the plurality of uplink channels / signals is a periodic uplink channel / signal.

[0143] Optionally, the uplink channel / signal includes:

[0144] The system includes: a semi-persistent PUSCH (SPS PUSCH); a physical uplink control channel (PUCCH) carrying acknowledgment / non-acknowledgment (ACK / NACK) information corresponding to the semi-persistent physical downlink shared channel (SPS-PDSCH); a physical uplink control channel (PUCCH) carrying periodic channel state information (P-CSI); a physical uplink control channel (PUCCH) carrying semi-persistent channel state information (SPS-CSI); a physical uplink shared channel (PUSCH) carrying semi-persistent channel state information (SPS-CSI); and a physical uplink control channel (PUCC H) carrying scheduling requests (SR).

[0145] In this embodiment of the invention, when multiple uplink channels / signals transmitted within a target time unit overlap at least partially in the time domain, the terminal device can determine, through constraints, whether to multiplex the information carried in the multiple uplink channels / signals for transmission in one channel / signal within the target time unit, thereby effectively transmitting the information to be transmitted.

[0146] Optionally, in this embodiment of the invention, the specific content of the above-mentioned constraints can be determined according to the specific types of the plurality of uplink channels / signals.

[0147] The constraints of the embodiments of the present invention will be described below with reference to the accompanying drawings and specific scenarios:

[0148] In one embodiment, the plurality of uplink channels / signals may include at least one Physical Uplink Control Channel (PUCCH) for carrying acknowledgment / non-acknowledgment (ACK / NACK) information corresponding to a Semi-Persistent Physical Downlink Shared Channel (SPS-PDSCH); the target channel / signal is the last SPS-PDSCH among the at least one PUCCH. The following example illustrates this with the plurality of uplink channels / signals including a PUCCH for carrying ACK / NACK information corresponding to an SPS-PDSCH. Figure 3 An example is provided where the first symbol of the earliest uplink channel / signal among the multiple uplink channels / signals is not earlier than the Ath symbol after the start time of the target channel / signal:

[0149] like Figure 3 As shown, the multiple uplink channels include: a PUCCH for carrying ACK / NACK information corresponding to SPS-PDSCH and an uplink channel / signal for carrying SPS-PUSCH / SPS-CSI / P-CSI / SR. The uplink channel / signal for carrying SPS-PUSCH / SPS-CSI / P-CSI / SR can be any one of SPS PUSCH, PUCCH carrying ACK / NACK information corresponding to SPS-PDSCH, PUCCH carrying P-CSI, PUCCH carrying SPS-CSI, PUSCH carrying SPS-CSI, and PUCCH carrying SR.

[0150] like Figure 3As shown, since the uplink channel / signal used to carry SPS-PUSCH / SPS-CSI / P-CSI / SR is earlier than the PUCCH used to carry the ACK / NACK information corresponding to SPS-PDSCH, the terminal device can determine whether the PUCCH used to carry the ACK / NACK information corresponding to SPS-PDSCH and the SPS-PDSCH satisfy the constraint conditions. If the constraint conditions are satisfied, the uplink channel / signal used to carry SPS-PUSCH / SPS-CSI / P-CSI / SR and the PUCCH used to carry the ACK / NACK information corresponding to SPS-PDSCH are multiplexed onto a single channel / signal for transmission. The channel / signal can be either the uplink channel / signal used to carry SPS-PUSCH / SPS-CSI / P-CSI / SR or the PUCCH used to carry ACK / NACK information corresponding to SPS-PDSCH. Alternatively, it can be selected from the uplink channel / signal used to carry SPS-PUSCH / SPS-CSI / P-CSI / SR or the PUCCH used to carry ACK / NACK information corresponding to SPS-PDSCH and multiplexed according to, for example, a judgment criterion.

[0151] like Figure 3 As shown, since the first symbol of the uplink channel / signal used to carry SPS-PUSCH / SPS-CSI / P-CSI / SR is no earlier than the Ath symbol after the start time of SPS-PDSCH, where A is a non-negative integer, and the start time of the uplink channel / signal used to carry SPS-PUSCH / SPS-CSI / P-CSI / SR is no earlier than the Bth symbol after the last symbol of SPS-PDSCH, where B is a non-negative integer, it can be determined that the PUCCH used to carry the ACK / NACK information corresponding to SPS-PDSCH and the SPS-PDSCH satisfy the constraint conditions.

[0152] It should be understood that Figure 3 The block diagram showing multiple uplink channels / signals that partially overlap in the time domain is merely an example. In other alternative embodiments, the multiple uplink channels / signals may also include other types of uplink periodic signals, and the multiple uplink channels / signals may also include multiple SPS-PDSCHs.

[0153] For example, such as Figure 4As shown, the plurality of uplink channels / signals may include: a PUCCH for carrying ACK / NACK 1 information corresponding to SPS-PDSCH 1 and a PUCCH for carrying ACK / NACK 2 information corresponding to SPS-PDSCH 2. In this embodiment of the invention, the target channel / signal may be the last SPS-PDSCH among the at least one PUCCH corresponding to SPS-PDSCH, i.e., SPS-PDSCH 1.

[0154] In another embodiment, the plurality of uplink channels / signals does not include the PUCCH used to carry ACK / NACK information corresponding to the SPS-PDSCH; the target channel / signal is the last uplink channel / signal among the plurality of uplink channels / signals transmitted before the target time unit.

[0155] For example, such as Figure 5 As shown, the plurality of uplink channels / signals may include a first-cycle uplink channel / signal (CH11) and a second-cycle uplink channel / signal (CH12), wherein the first-cycle uplink channel / signal and the second-cycle channel / signal may be uplink channels / signals used to carry SPS-PUSCH / SPS-CSI / P-CSI / SR. Since the second-cycle uplink channel / signal is earlier than the first-cycle uplink channel / signal within the target time unit, and the plurality of uplink channels / signals transmitted before the target time unit (such as...) Figure 5 The last uplink channel / signal in CH 21 and CH 22 shown is the first cycle uplink channel / signal (CH 21). Therefore, it can be determined whether the information carried in CH 12 and CH 11 should be multiplexed into one uplink channel / signal for transmission by judging whether the constraint conditions between CH 12 and CH 21 are met.

[0156] like Figure 5 As shown, the first symbol of CH 12 is no earlier than the Ath symbol after the start time of CH 21, where A is a non-negative integer. Therefore, it can be determined that CH 12 and CH 21 satisfy the constraint condition, and the information carried in CH 12 and CH 21 can be multiplexed and transmitted in a single uplink channel / signal.

[0157] It should be understood that Figure 5 CH 21 shown is CH 11 sent by the terminal device before the target time unit. Figure 5CH 22 shown is CH 12 transmitted by the terminal device before the target time unit. This embodiment of the invention aims to illustrate that CH 21 and CH 11 belong to the same period uplink channel signal, and does not limit the specific content between CH 21 and CH 11. For example, the content of CH 21 and CH 11 can be the same or different. Correspondingly, the content of CH 22 and CH 12 can be the same or different.

[0158] It should also be understood that the terminal device in the embodiments of the present invention can determine whether the information carried in the multiple uplink channels / signals in the target time unit meets the constraint conditions and transmit it by multiplexing one uplink channel / signal in the target time unit. However, the embodiments of the present invention do not limit which uplink channel / signal in the target time unit is specifically multiplexed or the specific operation when the multiple uplink channels / signals do not meet the constraint conditions.

[0159] The following is an illustrative example of the specific operation of the terminal device when multiple uplink channels / signals do not meet the constraints:

[0160] As an example, if the plurality of uplink channels / signals may include at least one Physical Uplink Control Channel (PUCCH) for carrying acknowledgment / non-acknowledgment (ACK / NACK) information corresponding to a Semi-Persistent Physical Downlink Shared Channel (SPS-PDSCH), then when the terminal device determines that the plurality of uplink channels / signals does not meet the constraint condition, it transmits one of the at least one PUCCH. As another example, when the terminal device determines that the plurality of uplink channels / signals does not meet the constraint condition, it determines that the plurality of uplink channels / signals to be transmitted within the target time unit are erroneous. As yet another example, when the terminal device determines that the plurality of uplink channels / signals does not meet the constraint condition, it transmits the earliest uplink channel / signal among the plurality of uplink channels / signals.

[0161] The above text combines Figures 2 to 5 This application describes in detail the wireless communication method according to embodiments of the present application from the perspective of a terminal device, but the embodiments of the present invention are not limited thereto. Figure 2 As shown, the method of this embodiment can also be applied to network devices. Accordingly, the network device determines the plurality of uplink channels / signals. When the plurality of uplink channels / signals meet the constraint conditions, the network device receives one uplink channel / signal within the target time unit.

[0162] Specifically, the network device determines multiple uplink channels / signals transmitted within a target time unit, and these multiple uplink channels / signals at least partially overlap in the time domain; when the multiple uplink channels / signals satisfy the constraint conditions, the network device receives one channel / signal within the target time unit, and the information carried in the multiple uplink channels / signals is multiplexed and transmitted in the one channel / signal; wherein, the constraint conditions include: the first symbol of the earliest uplink channel / signal among the multiple uplink channels / signals is not earlier than the Ath symbol after the start time or the last symbol of the target channel / signal, where A is a non-negative integer.

[0163] Optionally, A = N2 + 1, where N2 is the preparation time for PUSCH.

[0164] Optionally, A = N2 + d2,1, where N2 is the preparation time for PUSCH.

[0165] Optionally, the value of d2,1 is related to the structure of the demodulation reference signal (DMRS) in the PUSCH. For example, d2,1 = 0 if only the first time-domain symbol in the PUSCH includes DMRS; otherwise, d2,1 = 1.

[0166] Optionally, the constraint also includes: the start time of the earliest uplink channel / signal among the plurality of uplink channels / signals is no earlier than the Bth symbol after the last symbol of the target channel / signal, where B is a non-negative integer.

[0167] Optionally, B = N1 + 1 + d1,2, where N1 is the processing time of PDSCH.

[0168] Optionally, B = N2 + d1,1 + d1,2, where N1 is the processing time of PDSCH.

[0169] Optionally, the value of d1,1 depends on the corresponding ACK / NACK transmission method. For example, when using PUCCH to transmit the corresponding ACK / NACK, d1,1 = 0; when using PUSCH to transmit the corresponding ACK / NACK, d1,1 = 1.

[0170] Optionally, the values ​​of d1,2 are related to the PDSCH mapping method. For example, if the PDSCH mapping method is mapping type A as specified in Section 7.4.1.1 of 3GPP Technical Specification (TS) 38.211, and the last symbol of the PDSCH is on the i-th symbol in a slot less than 7, then d1,2 = 7 - i. As another example, if the PDSCH mapping method is mapping type B as specified in Section 7.4.1.1 of 3GPP Technical Specification (TS) 38.211, and the number of allocated PDSCH symbols is 4, then d1,2 = 3. As yet another example, if the PDSCH mapping method is mapping type B as specified in Section 7.4.1.1 of 3GPP Technical Specification (TS) 38.211, and the number of allocated PDSCH symbols is 2, then d1,2 = 3 + d, where d is the number of overlapping symbols between the scheduling PDCCH and the allocated PDSCH. For example, if the PDSCH mapping method is neither mapping type A nor mapping type B mentioned above, then d1,2 = 0.

[0171] Optionally, each of the plurality of uplink channels / signals is a periodic uplink channel / signal.

[0172] Optionally, the plurality of uplink channels / signals includes at least one PUCCH for carrying ACK / NACK information corresponding to the SPS-PDSCH; the target channel / signal is the last SPS-PDSCH among the SPS-PDSCHs corresponding to the at least one PUCCH.

[0173] Optionally, the plurality of uplink channels / signals does not include the PUCCH used to carry ACK / NACK information corresponding to the SPS-PDSCH; the target channel / signal is the last uplink channel / signal among the plurality of uplink channels / signals received before the target time unit.

[0174] Optionally, the method further includes:

[0175] When the network device determines that the plurality of uplink channels / signals do not meet the constraint, it receives one of the at least one PUCCHs.

[0176] Optionally, the method further includes:

[0177] When the network device determines that the multiple uplink channels / signals do not meet the constraint condition, it determines that the multiple uplink channels / signals to be transmitted in the target time unit are erroneous.

[0178] Optionally, the method further includes: when the network device determines that the plurality of uplink channels / signals do not meet the constraint condition, receiving the earliest uplink channel / signal among the plurality of uplink channels / signals.

[0179] Optionally, the uplink channel / signal includes:

[0180] The system includes: a semi-persistent PUSCH (SPS PUSCH); a physical uplink control channel (PUCCH) carrying acknowledgment / non-acknowledgment (ACK / NACK) information corresponding to the semi-persistent physical downlink shared channel (SPS-PDSCH); a physical uplink control channel (PUCCH) carrying periodic channel state information (P-CSI); a physical uplink control channel (PUCCH) carrying semi-persistent channel state information (SPS-CSI); a physical uplink shared channel (PUSCH) carrying semi-persistent channel state information (SPS-CSI); and a physical uplink control channel (PUCC H) carrying scheduling requests (SR).

[0181] It should be understood that the steps of wireless communication performed by network devices can be referenced. Figure 2 The corresponding steps in method 200 shown, and the method by which the network device determines whether the multiple uplink channels / signals meet the constraints, can be referred to the corresponding embodiments on the terminal device side described above. For the sake of brevity, they will not be repeated here.

[0182] Figure 6 A schematic flowchart of a wireless communication method 300 according to an embodiment of this application is shown. Figure 6 The terminal device shown can be, for example, Figure 1 The terminal device shown, Figure 6 The network device shown can be, for example, Figure 1 The access network device shown. Method 300 includes some or all of the following:

[0183] like Figure 6 As shown, the method 300 includes:

[0184] S310, the terminal device receives at least one Downlink Control Information (DCI) sent by the network device.

[0185] S320, the terminal device determines a plurality of uplink channels / signals transmitted within a target time unit, the plurality of uplink channels / signals at least partially overlapping in the time domain, and the at least one DCI is used to indicate at least one uplink signal / signal among the plurality of uplink channels / signals.

[0186] S330, the network device identifies the multiple uplink channels / signals.

[0187] S340, when the multiple uplink channels / signals meet the constraints, the terminal device multiplexes the information carried in the multiple uplink channels / signals into one channel / signal within the target time unit for transmission.

[0188] The constraint includes the following: the first symbol of the earliest uplink channel / signal among the plurality of uplink channels / signals is not earlier than the Ath symbol after the last symbol in the PDCCH carrying the at least one DCI, where A is a non-negative integer.

[0189] Optionally, A = N2 + 1, where N2 is the preparation time for scheduling the Physical Uplink Shared Channel (PUSCH).

[0190] Optionally, A = N2 + d2,1, where N2 is the preparation time for PUSCH.

[0191] Optionally, the value of d2,1 is related to the structure of the demodulation reference signal (DMRS) in the PUSCH. For example, d2,1 = 0 if only the first time-domain symbol in the PUSCH includes DMRS; otherwise, d2,1 = 1.

[0192] In one embodiment, the plurality of uplink channels / signals includes at least one PUCCH carrying ACK / NACK information corresponding to the target PDSCH; wherein the constraint further includes: the first symbol of the earliest uplink channel / signal among the plurality of uplink channels / signals is not earlier than the Bth symbol after the last symbol of the at least one target PDSCH, where B is a non-negative integer.

[0193] Alternatively, B = N1 + 1 + d 1,2 , where N1 is the PDSCH processing time.

[0194] Optionally, B = N2 + d1,1 + d1,2, where N1 is the processing time of PDSCH.

[0195] Optionally, the value of d1,1 depends on the corresponding ACK / NACK transmission method. For example, when using PUCCH to transmit the corresponding ACK / NACK, d1,1 = 0; when using PUSCH to transmit the corresponding ACK / NACK, d1,1 = 1.

[0196] Optionally, the values ​​of d1,2 are related to the PDSCH mapping method. For example, if the PDSCH mapping method is mapping type A as specified in Section 7.4.1.1 of 3GPP Technical Specification (TS) 38.211, and the last symbol of the PDSCH is on the i-th symbol in a slot less than 7, then d1,2 = 7 - i. As another example, if the PDSCH mapping method is mapping type B as specified in Section 7.4.1.1 of 3GPP Technical Specification (TS) 38.211, and the number of allocated PDSCH symbols is 4, then d1,2 = 3. As yet another example, if the PDSCH mapping method is mapping type B as specified in Section 7.4.1.1 of 3GPP Technical Specification (TS) 38.211, and the number of allocated PDSCH symbols is 2, then d1,2 = 3 + d, where d is the number of overlapping symbols between the scheduling PDCCH and the allocated PDSCH. For example, if the PDSCH mapping method is neither mapping type A nor mapping type B mentioned above, then d1,2 = 0.

[0197] Optionally, the at least one DCI includes:

[0198] The DCI used for scheduling the PUSCH, and the plurality of uplink channels / signals include the PUSCH; and / or, the DCI used for indicating the release of downlink quasi-persistent DL SPS resources, and the plurality of uplink channels / signals include the PUCCH carrying the ACK / NACK information corresponding to the DCI indicating the release of DL SPS resources; and / or, the DCI used for scheduling the physical downlink shared channel PDSCH, and the plurality of uplink channels / signals include the PUCCH carrying the ACK / NACK information corresponding to the PDSCH.

[0199] Optionally, the uplink channel / signal includes:

[0200] The system includes: a dynamically scheduled physical uplink shared channel (PUSCH); a semi-persistent scheduling PUSCH (SPS PUSCH); a physical uplink control channel (PUCCH) carrying acknowledgment / non-acknowledgment (ACK / NACK) information corresponding to the semi-persistent scheduling physical downlink shared channel (SPS-PDSCH); a physical uplink control channel (PUCCH) carrying periodic channel state information (P-CSI); a physical uplink control channel (PUCCH) carrying semi-persistent channel state information (SPS-CSI); a physical uplink shared channel (PUSCH) carrying quasi-persistent channel state information (SPS-CSI); and a physical uplink control channel (PUCC H) carrying scheduling requests (SR).

[0201] The constraints of embodiments of the present invention will be described by way of example below with reference to the accompanying drawings:

[0202] Figure 7 This is a schematic block diagram illustrating the constraint in a scenario where the multiple uplink channels / signals include at least one PUCCH carrying ACK / NACK information corresponding to the target PDSCH.

[0203] like Figure 7 As shown, the terminal device receives DCI 1 and DCI 2 sent by the network device. DCI 1 is a DCI used for scheduling PUSCH, and the plurality of uplink channels / signals includes the PUSCH. DCI 2 is a DCI used for scheduling PDSCH, and the plurality of uplink channels / signals includes PUCCH carrying ACK / NACK information corresponding to the PDSCH.

[0204] The constraint includes the following: the first symbol of the earliest uplink channel / signal among the plurality of uplink channels / signals is not earlier than the Ath symbol after the last symbol in the PDCCH carrying the at least one DCI, where A is a non-negative integer.

[0205] Specifically, the terminal device can determine that the earliest uplink channel / signal among the plurality of uplink channels / signals is the PUSCH scheduled for DCI 1, the last symbol in the PDCCH used to carry the at least one DCI is the PDCCH used to carry the DCI 1, and the first symbol of the PUSCH scheduled for DCI 1 is no earlier than the Ath symbol after the last symbol in the PDCCH carrying the at least one DCI 1, where A is a non-negative integer.

[0206] Furthermore, the constraint also includes: the first symbol of the earliest uplink channel / signal among the plurality of uplink channels / signals is no earlier than the Bth symbol after the last symbol of the at least one target PDSCH, where B is a non-negative integer. Specifically, the terminal device can determine that the earliest uplink channel / signal among the plurality of uplink channels / signals is the PUSCH scheduled by DCI 1, and the last symbol of the at least one target PDSCH is the PDSCH scheduled by DCI 2. Therefore, the first symbol of the PUSCH scheduled by DCI 1 is no earlier than the Bth symbol after the last symbol of the PDSCH scheduled by DCI 2.

[0207] Therefore, the terminal device is able to determine that the multiple uplink channels / signals satisfy the constraint condition.

[0208] It should be understood that Figure 7 This is merely an example where the plurality of uplink channels / signals include a PUCCH carrying ACK / NACK information corresponding to the target PDSCH. In this example, the aforementioned at least one DCI includes DCI 1 and DCI 2, wherein DCI 1 is a DCI used for scheduling PUSCH, and the plurality of uplink channels / signals include the PUSCH. DCI 2 is a DCI used for scheduling PDSCH, and the plurality of uplink channels / signals include a PUCCH carrying ACK / NACK information corresponding to the PDSCH. However, the embodiments of the present invention are not limited to this.

[0209] For example, such as Figure 8 As shown, the at least one DCI may include only DCI 2.

[0210] For example, such as Figure 9 As shown, the at least one DCI may include only DCI 1. In addition, the multiple uplink channels / signals may include a physical uplink control channel (PUCCH) carrying acknowledgment / non-acknowledgment (ACK / NACK) information corresponding to the quasi-persistent scheduling physical downlink shared channel (SPS-PDSCH). In this case, the SPS-PDSCH can be used as the target PDSCH in the embodiments of the present invention.

[0211] It should also be understood that Figures 7 to 9In the example, the multiple uplink channels / signals satisfy the constraint condition that the multiple uplink channels / signals simultaneously meet the following conditions: the first symbol of the earliest uplink channel / signal is not earlier than the Ath symbol after the last symbol in the PDCCH carrying the at least one DCI, where A is a non-negative integer. Furthermore, the first symbol of the earliest uplink channel / signal is not earlier than the Bth symbol after the last symbol in the at least one target PDSCH, where B is a non-negative integer. However, the embodiments of the present invention are not limited to this.

[0212] Figure 10 This is a schematic block diagram illustrating the constraint conditions in a scenario where the multiple uplink channels / signals in this embodiment of the invention include the DCI 1-scheduled PUSCH and other periodic uplink channels / signals. Figure 10 As shown, the multiple uplink channels / signals include the PUSCH scheduled by DCI 1 and periodic uplink channels / signals used to carry SPS-CSI / P-CSI / SR. In this case, if the first symbol of the earliest uplink channel / signal among the multiple uplink channels / signals is no earlier than the Ath symbol after the last symbol in the PDCCH carrying the at least one DCI, where A is a non-negative integer, the terminal device can determine that the multiple uplink channels / signals satisfy the constraint condition.

[0213] Specifically, the terminal device can determine that the PUSCH scheduled by DCI 1 is earlier than the periodic uplink channel / signal used to carry SPS-CSI / P-CSI / SR, and further, the PUSCH scheduled by DCI 1 is not earlier than the Ath symbol after the last symbol of the periodic uplink channel / signal used to carry SPS-CSI / P-CSI / SR.

[0214] Taking the target time unit as slot n as an example, in this embodiment of the invention, the terminal device needs to transmit a PUCCH and at least one other uplink channel (PUCCH or PUSCH) in slot n, and the PUCCH and at least one other uplink channel overlap in time. The terminal device receives at least one DCI, which is used to indicate uplink transmission in slot n (DCI scheduling PUSCH transmission in slot n; or DCI scheduling PDSCH transmission, and the ACK / NACK information corresponding to the PDSCH is transmitted in slot n; or DCI indicating DL SPS resource release, and the ACK / NACK information corresponding to the DCI is transmitted in slot n). Figures 7 to 10 As shown, if a PUCCH and at least one other uplink channel satisfy the following conditions, then all UCI or data information can be carried through one uplink channel.

[0215] If at least one PDSCH has its corresponding ACK / NACK information transmitted in slot n, then the first symbol of the earliest channel in the overlapping channels is no earlier than the Ath symbol after the last symbol in the PDCCH carrying that at least one DCI. And / or,

[0216] If at least one PDSCH has its corresponding ACK / NACK information transmitted in slot n, then the first symbol of the earliest channel in the overlapping channels is no earlier than the Bth symbol after the last PDSCH in the at least one PDSCH.

[0217] The above text combines Figures 6 to 10 This document describes in detail, from the perspective of the terminal device, how to determine the constraint conditions when the terminal device receives DCI according to embodiments of this application; however, embodiments of the present invention are not limited thereto. For example... Figure 6 As shown, the method of this embodiment can also be applied to network devices. Accordingly, the network device sends at least one DCI to the terminal device; the network device determines multiple uplink channels / signals transmitted within a target time unit, the multiple uplink channels / signals at least partially overlapping in the time domain, and the at least one DCI is used to indicate at least one uplink signal / signal among the multiple uplink channels / signals; when the multiple uplink channels / signals satisfy a constraint condition, the network device receives one channel / signal within the target time unit, and the information carried in the multiple uplink channels / signals is multiplexed and transmitted in the single channel / signal. The constraint condition includes:

[0218] The first symbol of the earliest uplink channel / signal among the plurality of uplink channels / signals is no earlier than the Ath symbol following the last symbol in the PDCCH carrying the at least one DCI, where A is a non-negative integer.

[0219] Optionally, A = N2 + 1, where N2 is the preparation time for scheduling PUSCH.

[0220] Optionally, A = N2 + d2,1, where N2 is the preparation time for PUSCH.

[0221] Optionally, the value of d2,1 is related to the structure of the demodulation reference signal (DMRS) in the PUSCH. For example, d2,1 = 0 if only the first time-domain symbol in the PUSCH includes DMRS; otherwise, d2,1 = 1.

[0222] Optionally, the plurality of uplink channels / signals includes at least one PUCCH carrying ACK / NACK information corresponding to the target PDSCH; wherein the constraint further includes:

[0223] The first symbol of the earliest uplink channel / signal among the plurality of uplink channels / signals is not earlier than the Bth symbol after the last symbol of the at least one target PDSCH, where B is a non-negative integer.

[0224] Alternatively, B = N1 + 1 + d 1,2 , where N1 is the PDSCH processing time.

[0225] Optionally, B = N2 + d1,1 + d1,2, where N1 is the processing time of PDSCH.

[0226] Optionally, the value of d1,1 depends on the corresponding ACK / NACK transmission method. For example, when using PUCCH to transmit the corresponding ACK / NACK, d1,1 = 0; when using PUSCH to transmit the corresponding ACK / NACK, d1,1 = 1.

[0227] Optionally, the values ​​of d1,2 are related to the PDSCH mapping method. For example, if the PDSCH mapping method is mapping type A as specified in Section 7.4.1.1 of 3GPP Technical Specification (TS) 38.211, and the last symbol of the PDSCH is on the i-th symbol in a slot less than 7, then d1,2 = 7 - i. As another example, if the PDSCH mapping method is mapping type B as specified in Section 7.4.1.1 of 3GPP Technical Specification (TS) 38.211, and the number of allocated PDSCH symbols is 4, then d1,2 = 3. As yet another example, if the PDSCH mapping method is mapping type B as specified in Section 7.4.1.1 of 3GPP Technical Specification (TS) 38.211, and the number of allocated PDSCH symbols is 2, then d1,2 = 3 + d, where d is the number of overlapping symbols between the scheduling PDCCH and the allocated PDSCH. For example, if the PDSCH mapping method is neither mapping type A nor mapping type B mentioned above, then d1,2 = 0.

[0228] Optionally, the at least one DCI includes:

[0232] In this embodiment of the invention, the plurality of uplink channels / signals may include more than two uplink channels / signals, so the terminal device or the network device needs to determine the uplink channel / signal used for actual transmission from the plurality of uplink channels / signals.

[0233] The following example illustrates how the multiple uplink channels / signals include at least one PUCCH and multiple PUSCHs, and how the uplink control information carried in the at least one PUCCH is multiplexed and transmitted in the target PUSCH among the multiple PUSCHs:

[0234] Figure 11 and Figure 12 All of these are schematic flowcharts illustrating the determination of the target PUSCH in embodiments of the present invention.

[0245] Optionally, the target PUSCH is the earliest PUSCH among those that satisfy the constraints. Specifically, if a PUCCH overlaps with multiple PUSCHs in the time domain, the terminal device or network device selects the first PUSCH among the multiple PUSCHs that satisfies the agreed conditions to carry the content of that PUCCH.

[0246] Optionally, the target PUSCH can be any PUSCH among those that satisfy the constraints.

[0247] In short, the terminal device or network device first determines at least one PUCCH and multiple PUSCHs that at least partially overlap in the time domain. Then, it determines the PUSCH that satisfies the constraints among the multiple PUSCHs. Further, it determines the target PUSCH among the PUSCHs that satisfy the constraints. Further still, after determining the target PUSCH, the terminal device uses the target PUSCH to transmit the uplink control information carried in the at least one PUCCH, and the network device receives the target PUSCH accordingly. It should be understood that the constraints are any of the constraints involved in the above embodiments, and will not be repeated here to avoid repetition.

[0255] S550, the network device uses the target PUSCH to transmit the uplink control information carried in the at least one PUCCH.

[0256] Optionally, the target PUSCH is the earliest PUSCH among those that satisfy the constraints. Specifically, if a PUCCH overlaps with multiple PUSCHs in the time domain, the terminal device or network device selects the first PUSCH among the multiple PUSCHs that satisfies the agreed conditions to carry the content of that PUCCH.

[0257] Optionally, the target PUSCH can be any PUSCH among those that satisfy the constraints.

[0258] In short, the terminal device or network device first identifies at least one PUCCH and multiple PUSCHs that at least partially overlap in the time domain, and the at least one PUCCH and the multiple PUSCHs satisfy a constraint condition. Then, a target PUSCH is identified among the PUSCHs that satisfy the constraint condition. After the target PUSCH is identified, the terminal device uses the target PUSCH to transmit the uplink control information carried in the at least one PUCCH, and the network device receives the target PUSCH accordingly. It should be understood that the constraint condition is any of the constraints involved in the above embodiments, and will not be repeated here to avoid repetition.
