The CU-DU structure can separate the protocol layer of the access network device. Some protocol layer functions are centrally controlled by the CU, while the remaining part or all protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0144] In some embodiments, the core network equipment may be a single device, multiple devices, or a group of devices. The core network may include at least one of the following: Evolved Packet Core (EPC), 5G Core Network (5GCN), and Next Generation Core (NGC).

As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0146] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are examples. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. ​​The number and form of each main body are arbitrary.

[0148] In some embodiments, the design of the sensing reference signal (sensing RS) mainly takes two directions. One is to introduce a new signal, sensing RS, with a corresponding time-frequency domain pattern (the time-domain symbols occupied by the sensing signal need to avoid synchronization or reference signals). The other is to multiplex or enhance existing uplink or downlink signals, such as multiplexing the Channel State Information-Reference Signal (CSI-RS), Synchronization Signal / PBCH (Physical Broadcast Channel) Block (SSB), and Positioning Reference Signal (PRS) signals, and using these signals to implement the sensing function.

[0149] In some embodiments of this disclosure, when a terminal transmits an uplink channel or signal, there may be time-domain overlap between uplink signals. For example, when the Physical Uplink Control Channel (PUCCH) and the Physical Uplink Shared Channel (PUSCH) overlap in the time domain, multiplexing rules are specified between PUCCH and PUSCH. When the Sounding Reference Signal (SRS) overlaps with the uplink channel PUCCH or PUSCH, some drop rules are specified to avoid conflicts.

[0150] In some embodiments, when the sensing RS design introduces a new reference signal, and the sensing mode is that the UE transmits sensing RS, how to handle the conflict when the UE transmits sensing RS on one carrier and there is time domain overlap with other uplink signals or channels is an urgent problem to be solved.

[0151] Figure 2A is an interactive schematic diagram illustrating a communication method according to an embodiment of the present disclosure. As shown in Figure 2A, the embodiments of the present disclosure relate to a communication method, which includes:

[0152] Step S2101: Terminal 101 determines that the sensing signal and SRS have temporal overlap.

[0153] In some embodiments, the sensing signal may be a signal used to implement ISAC.

[0154] In some embodiments, the sensing signals can be used for information transmission, or for environmental perception and target detection.

[0155] In some embodiments, the sensing signal may also be referred to as sensing RS.

[0156] In some embodiments, the time-domain overlap between the sensing signal and the uplink signal can be understood as the sensing signal and the uplink signal needing to be sent in the same time window, or the sensing signal and the uplink signal needing to arrive at the network device 102 in the same time window.

[0157] In some embodiments, temporal overlap may also be referred to as temporal resource overlap.

[0158] Step S2102: Terminal 101 sends a sensing signal or SRS to network device 102.

[0159] In some embodiments, network device 102 receives sensing signals or SRS sent by terminal 101, but is not limited thereto. Network device 102 may also receive sensing signals or SRS sent by other subjects, in which case step S2102 may be omitted.

[0160] In some embodiments, transmitting a sensing signal or SRS may include at least one of the following:

[0161] Send sensing signals, but do not send SRS;

[0162] Send SRS, but do not send sensing signals;

[0163] Based on the first information, a sensing signal or SRS is sent to network device 102;

[0164] The first information includes at least one of the following: the transmission method of the sensing signal, the transmission method of the SRS, the priority of the sensing signal, and the priority of the SRS; the priority of the sensing signal is determined based on the priority value of the sensing signal, and the priority of the SRS is determined based on the priority value of the SRS.

[0168] In some embodiments, the priority value of the sensing signal is at least one of the following: predefined, preconfigured, or a downlink control information (DCI) indication sent by triggering terminal 101 to the sensing signal.

[0169] For example, the priority value of the sensing signal is predefined; for another example, the priority value of the sensing signal is preconfigured; and for yet another example, the priority value of the sensing signal is triggered by the terminal 101 to send the DCI indication of the sensing signal.

[0170] In some embodiments, the smaller the priority value of the sensing signal, the higher the priority of the sensing signal.

[0171] In one implementation, two priority values ​​can be defined for the sensing signal: 0 and 1, with priority value 0 corresponding to a higher priority than priority value 1.

[0172] In another implementation, multiple priority values ​​can be defined for the sensing signal, such as priority values ​​{0, 1, 2, 3... 7}, where priority value 0 corresponds to the highest priority and priority value 7 corresponds to the lowest priority.

[0173] In some embodiments, the smaller the priority value of the SRS, the higher the priority of the SRS.

[0174] In some embodiments, the SRS priority is low by default.

[0175] In some embodiments, SRS is an aperiodic SRS transmission triggered by the DCI format of the scheduling data (including DCI format 0_0 / 0_1 / 0_2 / 10 / 1_1 / 1_2), and the priority value of the triggered aperiodic SRS is determined according to the priority field in the DCI.

[0176] In some embodiments, if no priority value is defined for the sensing signal, the sensing signal or SRS can be sent to the network device 102 according to a transmission rule other than the priority. For example, the sensing signal is sent but the SRS is not sent; another example is that the SRS is sent but the sensing signal is not sent; yet another example is that the sensing signal or SRS is sent to the network device 102 according to the transmission method of the sensing signal and / or the transmission method of the SRS.

[0177] In some embodiments, if the sensing signal and SRS overlap in the time domain, the sensing signal is sent to the network device 102, and the SRS is not sent.

[0178] In some embodiments, if the sensing signal and the SRS overlap in the time domain, the SRS is sent to the network device 102, and the sensing signal is not sent.

[0180] Both the sensing signal and SRS are transmitted in a semi-static or periodic manner, sending the sensing signal or SRS to the network device 102.

[0181] The SRS is sent aperiodically to network device 102;

[0182] The sensing signal is transmitted aperiodically, and the SRS is transmitted semi-statically or periodically, sending the sensing signal to network device 102.

[0183] In some embodiments, if the sensing signal and SRS overlap in the time domain, and both the sensing signal and SRS are transmitted in a semi-static or periodic manner, the sensing signal is sent to the network device 102, but the SRS is not sent.

[0184] In some embodiments, if the sensing signal and SRS overlap in the time domain, and both the sensing signal and SRS are transmitted in a semi-static or periodic manner, the SRS is sent to the network device 102, but the sensing signal is not sent.

[0185] In some embodiments, if the sensing signal and the SRS overlap in the time domain, and the SRS is transmitted aperiodically while the sensing signal is transmitted semi-statically or periodically, the SRS is sent to the network device 102, but the sensing signal is not sent.

[0186] In some embodiments, if the sensing signal and the SRS overlap in the time domain, and the SRS is transmitted aperiodically, the sensing signal is also transmitted aperiodically, and the SRS is sent to the network device 102, but the sensing signal is not sent.

[0187] In some embodiments, if the sensing signal and SRS overlap in the time domain, the sensing signal is transmitted in an aperiodic manner, and the SRS is transmitted in a semi-static or periodic manner, the sensing signal is sent to the network device 102, but the SRS is not sent.

[0188] In some embodiments, if a priority value is defined for the sensing signal, the sensing signal or the SRS can be sent to the network device 102 according to the priority of the sensing signal and the priority of the SRS.

[0189] In some embodiments, if the sensing signal and the SRS overlap in the time domain, then sending the sensing signal or the SRS to the network device 102 according to the priority of the sensing signal and the priority of the SRS includes at least one of the following:

[0190] The sensing signal has a higher priority than the SRS, and the sensing signal is sent to network device 102;

[0191] The priority of the sensing signal is lower than that of the SRS, so the SRS is sent to network device 102.

[0192] In some embodiments, if the sensing signal and the SRS overlap in the time domain and the priority of the sensing signal is higher than that of the SRS, then the sensing signal is sent to the network device 102.

[0193] In some embodiments, if the sensing signal and the SRS overlap in the time domain and the priority of the sensing signal is lower than that of the SRS, then the SRS is sent to the network device 102.

[0194] In some embodiments, if the sensing signal and the SRS overlap in the time domain and the priority of the sensing signal is the same as that of the SRS, the sensing signal can be sent to the network device 102 instead of the SRS.

[0195] In some embodiments, if the sensing signal and the SRS overlap in the time domain and the priority of the sensing signal is the same as that of the SRS, then the SRS can be sent to the network device 102 instead of the sensing signal.

[0196] In some embodiments, if the sensing signal and the SRS overlap in the time domain and the priority of the sensing signal is the same as the priority of the SRS, the sensing signal or the SRS can be sent to the network device 102 according to the transmission method of the sensing signal and / or the transmission method of the SRS.

[0197] In some embodiments, the fact that the priority of the sensing signal is the same as the priority of the SRS can be understood as the priority value of the sensing signal being the same as the priority value of the SRS.

[0198] Using the above method, when there is temporal overlap between the sensing signal and SRS, the terminal can send the sensing signal or SRS to the network device to avoid conflict between the sensing signal and SRS, thereby improving system performance.

[0199] The methods involved in the embodiments of this disclosure may include at least one of the steps S2101 to S2102 described above. For example, step S2101 may be implemented as a separate embodiment, and step S2102 may be implemented as a separate embodiment, but are not limited thereto.

[0203] In some embodiments, the sensing signal may be a signal used to implement ISAC.

[0204] In some embodiments, the sensing signals can be used for information transmission, or for environmental perception and target detection.

[0205] In some embodiments, the sensing signal may also be referred to as sensing RS.

[0206] In some embodiments, the temporal overlap between the sensing signal and the PUCCH can be understood as the sensing signal and the PUCCH needing to be sent in the same time window, or the sensing signal and the PUCCH needing to arrive at the network device 102 in the same time window.

[0207] In some embodiments, temporal overlap may also be referred to as temporal resource overlap.

[0208] Step S2202: Terminal 101 sends a sensing signal or PUCCH to network device 102.

[0209] In some embodiments, network device 102 receives a sensing signal or PUCCH sent by terminal 101, but is not limited thereto. Network device 102 may also receive a sensing signal or PUCCH sent by other entities, in which case step S2202 may be omitted.

[0213] Based on the first information, a sensing signal or PUCCH is sent to network device 102.

[0214] In some embodiments, the first information includes at least one of the following: the transmission method of the sensing signal, the information carried by the PUCCH, the priority of the sensing signal, and the priority of the PUCCH.

[0215] In some embodiments, the transmission method of the sensing signal includes at least one of the following: semi-static, periodic, and aperiodic.

[0218] Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) information;

[0219] Scheduling Request (SR);

[0220] Link Recovery Request (LRR);

[0221] Information on scheduling PUSCH.

[0222] In some embodiments, the information for scheduling PUSCH can be understood as PUCCH multiplexed from PUSCH.

[0223] In some embodiments, the information carried by the PUCCH is a CSI report.

[0224] In some embodiments, the information carried by the PUCCH is HARQ-ACK information.

[0225] In some embodiments, the information carried by the PUCCH is the SR.

[0228] In some embodiments, PUCCH is a PUCCH multiplexed from CSI and SR.

[0229] In some embodiments, PUCCH is a PUCCH multiplexed from CSI and LRR.

[0230] In some embodiments, PUCCH is a PUCCH multiplexed from HARQ-ACK information and SR.

[0231] In some embodiments, PUCCH is a PUCCH multiplexed from HARQ-ACK information and LRR.

[0234] In some embodiments, PUCCH is a PUCCH that multiplexes CSI, HARQ-ACK information, and LRR.

[0236] In some embodiments, PUCCH is a PUCCH that multiplexes CSI, HARQ-ACK information, SR, and LRR.

[0237] In some embodiments, the priority of the sensing signal is determined based on the priority value of the sensing signal.

[0238] In some embodiments, the priority value of the sensing signal is at least one of the following: predefined, preconfigured, or DCI indication of sending the sensing signal via trigger terminal 101.

[0240] In some embodiments, the smaller the priority value of the sensing signal, the higher the priority of the sensing signal.

[0241] In one implementation, two priority values ​​can be defined for the sensing signal: 0 and 1, with priority value 0 corresponding to a higher priority than priority value 1.

[0242] In another implementation, multiple priority values ​​can be defined for the sensing signal, such as priority values ​​{0, 1, 2, 3... 7}, where priority value 0 corresponds to the highest priority and priority value 7 corresponds to the lowest priority.

[0243] In some embodiments, the priority of PUCCH is determined based on the priority value of PUCCH.

[0244] In some embodiments, the smaller the priority value of PUCCH, the higher the priority of PUCCH.

[0245] In some embodiments, if the PUCCH carries a HARQ corresponding to the Physical Downlink Shared Channel (PDSCH) dynamically scheduled by the DCI, then the priority value of the PUCCH is the priority value indicated by the priority field carried in the DCI that schedules the PDSCH.

[0246] In some embodiments, if the PUCCH carries HARQ information of the PDSCH for semi-persistent scheduling (SPS), the higher-level parameters in the SPS configuration information directly indicate the priority value of the HARQ-ACK corresponding to the PDSCH of that SPS.

[0247] In some embodiments, if the information carried by the PUCCH is an SR, then the phy-PriorityIndex parameter in the PUCCH resource configuration indicates the priority value of the SR carried by the PUCCH resource.

[0248] In some embodiments, if the information carried by the PUCCH is a CSI triggered by DCI, the priority value of the PUCCH is determined according to the priority indication field in the DCI; otherwise, the PUCCH is of low priority.

[0249] In some embodiments, if the PUCCH is a multiplexed PUCCH and PUSCH, then the priority value of the PUCCH is the higher priority value between the PUSCH and the multiplexed PUCCH. For example, if the priority of the PUSCH is higher than the priority of the multiplexed PUCCH, then the priority value of the PUCCH is the priority value of the PUSCH; if the priority of the PUSCH is lower than the priority of the multiplexed PUCCH, then the priority value of the PUCCH is the priority value of the multiplexed PUCCH.

[0250] In some embodiments, if the CSI is transmitted in the PUCCH, it has a low priority.

[0251] In some embodiments, if no priority value is defined for the sensing signal, the sensing signal or PUCCH can be sent to the network device 102 according to a transmission rule other than priority. For example, the sensing signal is sent but the PUCCH is not sent; or the PUCCH is sent but the sensing signal is not sent; or the sensing signal or PUCCH is sent to the network device 102 according to the transmission method of the sensing signal and the information carried by the PUCCH.

[0253] In some embodiments, if the sensing signal and the PUCCH overlap in the time domain, the PUCCH is sent to the network device 102, and the sensing signal is not sent.

[0254] In some embodiments, if the sensing signal and the PUCCH overlap in the time domain, the sensing signal or the PUCCH is sent to the network device 102 according to the transmission method of the sensing signal and the information carried by the PUCCH.

[0256] In some embodiments, if the sensing signal and PUCCH overlap in the time domain, and the sensing signal is transmitted in a semi-static or periodic manner, the sensing signal is sent to the network device 102, but the PUCCH is not sent.

[0257] In some embodiments, if the sensing signal and PUCCH overlap in the time domain and the sensing signal is transmitted aperiodically, the sensing signal is sent to the network device 102, and the PUCCH is not sent.

[0258] For example, if the sensing signal and PUCCH overlap in the time domain, the sensing signal is transmitted in a semi-static or periodic manner, and the information carried by the PUCCH is a CSI report, then the PUCCH is sent to network device 102, and the sensing signal is not sent.

[0259] For example, if the sensing signal and PUCCH overlap in the time domain, the sensing signal is transmitted in a semi-static or periodic manner, and the information carried by the PUCCH is LRR, then the sensing signal is sent to network device 102, and the PUCCH is not sent.

[0260] For example, if the sensing signal and PUCCH overlap in the time domain, the sensing signal is transmitted non-periodicly, and the information carried by the PUCCH is SR, then the sensing signal is sent to the network device 102, and the PUCCH is not sent.

[0261] For example, if the sensing signal and PUCCH overlap in the time domain, the sensing signal is transmitted non-periodicly, and the PUCCH is a PUCCH that multiplexes CSI, HARQ-ACK information, and SR, then the PUCCH is sent to network device 102, and the sensing signal is not sent.

[0262] In some embodiments, if a priority value is defined for the sensing signal, the sensing signal or PUCCH can be sent to the network device 102 according to the priority of the sensing signal and the priority of the PUCCH.

[0263] In some embodiments, sending a sensing signal or a PUCCH to network device 102 according to the priority of the sensing signal and the priority of the PUCCH includes at least one of the following:

[0264] The sensing signal has a higher priority than the PUCCH signal, and is sent to network device 102.

[0265] The priority of the sensing signal is lower than that of the PUCCH, so the PUCCH is sent to network device 102.

[0266] In some embodiments, if the sensing signal and PUCCH overlap in the time domain and the priority of the sensing signal is higher than that of the PUCCH, the sensing signal is sent to the network device 102 instead of the PUCCH.

[0267] In some embodiments, if the sensing signal and the PUCCH overlap in the time domain and the priority of the sensing signal is lower than that of the PUCCH, then the PUCCH is sent to the network device 102 and the sensing signal is not sent.

[0268] In some embodiments, if the sensing signal and the PUCCH overlap in the time domain and the priority of the sensing signal is the same as that of the PUCCH, the sensing signal can be sent to the network device 102 instead of the PUCCH.

[0269] In some embodiments, if the sensing signal and the PUCCH overlap in the time domain and the priority of the sensing signal is the same as that of the PUCCH, then the PUCCH can be sent to the network device 102 instead of the sensing signal.

[0270] In some embodiments, if the sensing signal and the PUCCH overlap in the time domain and the priority of the sensing signal is the same as that of the PUCCH, the sensing signal or the PUCCH can be sent to the network device 102 according to the transmission method of the sensing signal and the information carried by the PUCCH.

[0271] In some embodiments, the fact that the priority of the sensing signal is the same as the priority of the PUCCH can be understood as the priority value of the sensing signal being the same as the priority value of the PUCCH.

[0272] Using the above method, when there is temporal overlap between the sensing signal and PUCCH, the terminal can send the sensing signal or PUCCH to the network device to avoid conflict between the sensing signal and PUCCH, thereby improving system performance.

[0273] The methods involved in the embodiments of this disclosure may include at least one of the steps S2201 to S2202 described above. For example, step S2201 may be implemented as a separate embodiment, and step S2202 may be implemented as a separate embodiment, but are not limited thereto.

[0299] In another implementation, multiple priority values ​​can be defined for the sensing signal, such as priority values ​​{0, 1, 2, 3... 7}, where priority value 0 corresponds to the highest priority and priority value 7 corresponds to the lowest priority.

[0300] In some embodiments, the priority of a PUSCH is determined based on its priority value.

[0301] In some embodiments, the smaller the priority value of PUSCH, the higher the priority of PUSCH.

[0302] In some embodiments, if the PUSCH carries an unreused PUSCH, the priority value of the PUSCH is the priority value indicated by the priority field when the DCI schedules the PUSCH.

[0303] In some embodiments, if the PUSCH is a multiplexed PUCCH and PUSCH, then the priority value of the PUSCH is the higher priority value between the PUSCH and the multiplexed PUCCH. For example, if the priority of the PUSCH is higher than the priority of the multiplexed PUCCH, then the priority value of the PUSCH is the priority value of the PUSCH; if the priority of the PUSCH is lower than the priority of the multiplexed PUCCH, then the priority value of the PUSCH is the priority value of the multiplexed PUCCH.

[0304] In some embodiments, if the PUSCH is scheduled by DCI, the priority value of the PUSCH is indicated in the priority field of the DCI.

[0305] In some embodiments, if the PUSCH is scheduled under Configured Grant Type 1 (CG1) and Configured Grant Type 2 (CG2), the priority value of the PUSCH is configured by higher-layer signaling.

[0306] In some embodiments, if CSI is transmitted in PUSCH, the priority is determined based on the priority value of PUSCH.

[0307] In some embodiments, if no priority value is defined for the sensing signal, the sensing signal or PUSCH can be sent to the network device 102 according to a sending rule other than priority. For example, the sensing signal is sent but the PUSCH is not sent; another example is that the PUSCH is sent but the sensing signal is not sent; yet another example is that the sensing signal or PUSCH is sent to the network device 102 according to the sending method of the sensing signal and the information carried by the PUSCH.

[0319] The sensing signal has a higher priority than the PUSCH signal, and the sensing signal is sent to network device 102.

[0320] The priority of the sensing signal is lower than that of the PUSCH, so the PUSCH is sent to network device 102.

[0321] In some embodiments, if the sensing signal and PUSCH overlap in the time domain and the priority of the sensing signal is higher than that of the PUSCH, the sensing signal is sent to the network device 102, and the PUSCH is not sent.

[0322] In some embodiments, if the sensing signal and PUSCH overlap in the time domain and the priority of the sensing signal is lower than that of the PUSCH, then the PUSCH is sent to the network device 102 and the sensing signal is not sent.

[0323] In some embodiments, if the sensing signal and the PUSCH overlap in the time domain and the priority of the sensing signal is the same as that of the PUSCH, the sensing signal can be sent to the network device 102 instead of the PUSCH.

[0324] In some embodiments, if the sensing signal and PUSCH overlap in the time domain and the priority of the sensing signal is the same as that of the PUSCH, then the PUSCH can be sent to the network device 102 instead of the sensing signal.

[0325] In some embodiments, if the sensing signal and the PUSCH overlap in the time domain and the priority of the sensing signal is the same as that of the PUSCH, the sensing signal or the PUSCH can be sent to the network device 102 according to the transmission method of the sensing signal and the information carried by the PUSCH.

[0326] In some embodiments, the fact that the priority of the sensing signal is the same as the priority of the PUSCH can be understood as the priority value of the sensing signal being the same as the priority value of the PUSCH.

[0327] Using the above method, when there is temporal overlap between the sensing signal and PUSCH, the terminal can send the sensing signal or PUSCH to the network device to avoid conflict between the sensing signal and PUSCH, thereby improving system performance.

[0328] The methods involved in the embodiments of this disclosure may include at least one of the steps S2301 to S2302 described above. For example, step S2301 may be implemented as a separate embodiment, and step S2302 may be implemented as a separate embodiment, but are not limited thereto.

[0329] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0330] Figure 2D is an interactive schematic diagram illustrating a communication method according to an embodiment of the present disclosure. This disclosure relates to a communication method, which includes:

[0331] Step S2401: Terminal 101 determines that the sensing signal and PRACH have temporal overlap.

[0332] In some embodiments, the sensing signal may be a signal used to implement ISAC.

[0333] In some embodiments, the sensing signals can be used for information transmission, or for environmental perception and target detection.

[0334] In some embodiments, the sensing signal may also be referred to as sensing RS.

[0335] In some embodiments, the temporal overlap between the sensing signal and PRACH can be understood as the sensing signal and PRACH needing to be sent in the same time window, or the sensing signal and PRACH needing to arrive at the network device 102 in the same time window.

[0336] In some embodiments, temporal overlap may also be referred to as temporal resource overlap.

[0337] Step S2402: Terminal 101 sends a sensing signal or PRACH to network device 102.

[0338] In some embodiments, network device 102 receives a sensing signal or PRACH sent by terminal 101, but is not limited thereto. Network device 102 may also receive a sensing signal or PRACH sent by other subjects, in which case step S2402 may be omitted.

[0339] In some embodiments, transmitting a sensing signal or PRACH may include at least one of the following:

[0340] Send a sensing signal, but do not send a PRACH signal;

[0341] Send PRACH, but do not send sensing signals;

[0342] Based on the first information, a sensing signal or PRACH is sent to network device 102.

[0343] In some embodiments, the first information includes at least one of the following: the transmission method of the sensing signal, the priority of the sensing signal, and the priority of PRACH.

[0344] In some embodiments, the transmission method of the sensing signal includes at least one of the following: semi-static, periodic, and aperiodic.

[0345] In some embodiments, the priority of the sensing signal is determined based on the priority value of the sensing signal.

[0346] In some embodiments, the priority value of the sensing signal is at least one of the following: predefined, preconfigured, or DCI indication of sending the sensing signal via trigger terminal 101.

[0347] For example, the priority value of the sensing signal is predefined; for another example, the priority value of the sensing signal is preconfigured; and for yet another example, the priority value of the sensing signal is triggered by the terminal 101 to send the DCI indication of the sensing signal.

[0348] In some embodiments, the smaller the priority value of the sensing signal, the higher the priority of the sensing signal.

[0349] In one implementation, two priority values ​​can be defined for the sensing signal: 0 and 1, with priority value 0 corresponding to a higher priority than priority value 1.

[0350] In another implementation, multiple priority values ​​can be defined for the sensing signal, such as priority values ​​{0, 1, 2, 3... 7}, where priority value 0 corresponds to the highest priority and priority value 7 corresponds to the lowest priority.

[0351] In some embodiments, the PRACH priority is set to low priority by default.

[0352] In some embodiments, if no priority value is defined for the sensing signal, the sensing signal or PRACH can be sent to the network device 102 according to a transmission rule other than priority. For example, the sensing signal is sent but the PRACH is not sent; another example is that the PRACH is sent but the sensing signal is not sent; yet another example is that the sensing signal or PRACH is sent to the network device 102 according to the transmission method of the sensing signal.

[0353] In some embodiments, if the sensing signal and PRACH overlap in the time domain, the sensing signal is sent to the network device 102, but the PRACH is not sent.

[0354] In some embodiments, if the sensing signal and PRACH overlap in the time domain, PRACH is sent to network device 102, and the sensing signal is not sent.

[0355] In some embodiments, if the sensing signal and PRACH overlap in the time domain, the sensing signal or PRACH is sent to the network device 102 according to the transmission method of the sensing signal.

[0356] In some embodiments, sending a sensing signal or PRACH to network device 102, depending on the transmission method of the sensing signal, includes at least one of the following:

[0357] The sensing signal is transmitted in a semi-static or periodic manner, sending PRACH to network device 102;

[0358] The sensing signal is transmitted aperiodically to network device 102.

[0359] In some embodiments, if the sensing signal and PRACH overlap in the time domain, and the sensing signal is transmitted in a semi-static or periodic manner, PRACH is sent to network device 102, but the sensing signal is not sent.

[0360] In some embodiments, if the sensing signal and PRACH overlap in the time domain and the sensing signal is transmitted aperiodically, the sensing signal is sent to the network device 102, but the PRACH is not sent.

[0361] In some embodiments, if a priority value is defined for the sensing signal, the sensing signal or PRACH can be sent to the network device 102 according to the priority of the sensing signal and the priority of PRACH.

[0362] In some embodiments, sending a sensing signal or a PRACH to network device 102 according to the priority of the sensing signal and the priority of the PRACH includes at least one of the following:

[0363] The sensing signal has a higher priority than the PRACH signal, and the sensing signal is sent to network device 102.

[0364] The priority of the sensing signal is lower than that of PRACH, so PRACH is sent to network device 102.

[0365] In some embodiments, if the sensing signal and PRACH overlap in the time domain and the priority of the sensing signal is higher than that of the PRACH, the sensing signal is sent to the network device 102 instead of the PRACH.

[0366] In some embodiments, if the sensing signal and PRACH overlap in the time domain and the priority of the sensing signal is lower than that of the PRACH, then the PRACH is sent to the network device 102 and the sensing signal is not sent.

[0367] In some embodiments, if the sensing signal and PRACH overlap in the time domain and the priority of the sensing signal is the same as that of the PRACH, the sensing signal can be sent to the network device 102 instead of the PRACH.

[0368] In some embodiments, if the sensing signal and PRACH overlap in the time domain and the priority of the sensing signal is the same as that of the PRACH, then the PRACH can be sent to the network device 102 instead of the sensing signal.

[0369] In some embodiments, if the sensing signal and PRACH overlap in the time domain and the priority of the sensing signal is the same as that of the PRACH, the sensing signal or PRACH can be sent to the network device 102 according to the transmission method of the sensing signal.

[0370] In some embodiments, the fact that the priority of the sensing signal is the same as the priority of PRACH can be understood as the priority value of the sensing signal being the same as the priority value of PRACH.

[0371] Using the above method, when there is temporal overlap between the sensing signal and PRACH, the terminal can send the sensing signal or PRACH to the network device to avoid conflict between the sensing signal and PRACH, thereby improving system performance.

[0372] The methods involved in the embodiments of this disclosure may include at least one of the steps S2401 to S2402 described above. For example, step S2401 may be implemented as a separate embodiment, and step S2402 may be implemented as a separate embodiment, but are not limited thereto.

[0402] In some embodiments, sending the sensing signal or the uplink signal to the network device includes any one of the following:

[0403] Send the sensing signal, but do not send the uplink signal;

[0404] Send the uplink signal, but do not send the sensing signal;

[0407] In some embodiments, the uplink signal is an SRS, and sending the sensing signal or the uplink signal to the network device according to the first information includes one of the following:

[0408] The sensing signal and the uplink signal are both transmitted in a semi-static or periodic manner, and the sensing signal or the uplink signal is sent to the network device.

[0409] The uplink signal is transmitted aperiodically to the network device.

[0410] The sensing signal is transmitted aperiodically, and the uplink signal is transmitted semi-statically or periodically to the network device.

[0412] The sensing signal or the uplink signal is sent to the network device according to the transmission method of the sensing signal and the information carried by the uplink signal.

[0424] The sensing signal or the uplink signal is sent to the network device according to the priority of the sensing signal and the priority of the uplink signal.

[0425] In some embodiments, sending the sensing signal or the uplink signal to the network device according to the priority of the sensing signal and the priority of the uplink signal includes one of the following:

[0426] The sensing signal has a higher priority than the uplink signal, and is sent to the network device.

[0427] The sensing signal has a lower priority than the uplink signal, and the uplink signal is sent to the network device.

[0428] In some embodiments, the priority value of the sensing signal is at least one of the following: a predefined downlink control information (DCI) indication that triggers the terminal to send the sensing signal.

[0429] In some embodiments, the UE transmits sensing RS on one carrier. The time domain resources of sensing RS and other uplink channels or uplink signals (such as PRACH, SRS, PUCCH (UCI), PUSCH) overlap. However, in order to ensure the low PAPR characteristic, only one uplink channel or signal can be transmitted on one uplink carrier.

[0430] In some embodiments, the transmission rules for signals when sensing RS and uplink signals or channels overlap are defined, such that low-priority channels or signals are not transmitted, and high-priority channels or signals are transmitted.

[0431] In some embodiments, a priority value is defined for the sensing RS, and the priority values ​​of the sensing RS and the uplink signal or channel are compared. If the channel or signal with lower priority is not transmitted, the channel or signal with higher priority is transmitted.

[0432] Example 1: When the time-domain resources of sensing RS and PUCCH overlap, the following signal transmission rules are used in the overlapping time (PUCCH is an unmultiplexed PUCCH, or a PUCCH multiplexed with PUSCH):

[0433] 1. Do not send Sensing RS, send PUCCH;

[0434] 2. Do not send PUCCH, send sensing RS;

[0435] 3. The transmission of signals or channels is determined based on one or more conditions, such as the transmission method of the sensing RS, the specific information carried in the PUCCH, and the priority value of the PUCCH.

[0436] In some embodiments, priority rules are defined in Tables 1 and 2 without defining priority values ​​for sensing RS. In Table 1, sensing RS refers to semi-static or periodic sensing RS transmissions, while in Table 2, sensing RS refers to aperiodic transmissions.

[0437] Table 1

[0438] Table 2

[0439] In some embodiments, when a priority value is defined for the sensing RS, the following transmission rules are defined:

[0440] Compare the priority values ​​of the sensing RS and the PUCCH, and do not send channels or signals with lower priority (where the priority values ​​of PUCCH are referenced in Table 6).

[0441] Optionally, the smaller the priority value, the higher the priority.

[0442] Optionally, the sensing RS priority value is predefined, preconfigured, or determined by triggering the UE to send a DCI indication of the sensing RS.

[0443] Optionally, when the sensing RS and PUCCH have the same priority value, the transmission of the signal or channel is determined according to the rules defined in Tables 1 and 2.

[0444] In some embodiments, when the PUCCH carries a HARQ corresponding to a PDSCH dynamically scheduled by the DCI, the priority value of the PUCCH is the priority value indicated by the priority field carried in the DCI that schedules the PDSCH; if the PUCCH carries SR information, the priority of the PUCCH is the priority of the SR carried by the PUCCH resource indicated by the parameter phy-PriorityIndex in the PUCCH resource configuration of the SR; when the PUCCH carries CSI information triggered by the DCI, the priority value of the PUCCH is determined according to the priority indication field in the DCI, otherwise the PUCCH is of low priority.

[0445] In some embodiments, if the PUCCH is a PUCCH multiplexed from the PUCCH and PUSCH, then the priority value of the PUCCH is the value corresponding to the higher priority of the PUSCH and the PUCCH multiplexed with it.

[0446] In some embodiments, two priority levels are defined for sensing RS, with priority values ​​of 0 and 1, where a value of 0 has a higher priority than a value of 1.

[0447] In some embodiments, multiple priority values ​​are defined for sensing RS, such as priority values ​​{0,1,2,3……7}, where a priority value of 0 indicates a higher priority.

[0448] Example 2: When the time-domain resources of sensing RS and PUSCH overlap (PUSCH is an unreused PUSCH, or a PUSCH multiplexed with PUCCH), the following signal transmission rules are used:

[0449] 1. Do not send sensing RS, send PUSCH;

[0450] 2. Do not send PUSCH, send sensing RS;

[0451] 3. The transmission of a signal or channel is determined based on one or more conditions, such as the transmission method of the sensing RS, the specific information carried in the PUSCH, and the priority value of the PUSCH.

[0452] In some embodiments, no priority value is defined for the sensing RS, and the signal transmission rules in Table 3 are defined instead. In Table 3, the sensing RS is either semi-static or periodic.

[0453] Table 3

[0454] In some embodiments, when a priority value is defined for the sensing RS, the following transmission rules are defined:

[0455] Compare the priority values ​​of the sensing RS and the PUSCH, and do not send channels or signals with lower priority (the priority values ​​of PUSCH are shown in Table 6).

[0456] Optionally, the smaller the priority value, the higher the priority.

[0457] Optionally, when the sensing RS and PUSCH have the same priority value, the transmission of the signal or channel is determined according to the rules defined in Table 3.

[0458] In some embodiments, if the PUSCH is an unreused PUSCH, the priority value of the PUSCH is the priority value indicated by the priority field when the DCI schedules the PUSCH; if the PUSCH is a PUSCH multiplexed from the PUCCH and the PUSCH, the priority value of the PUSCH is the value corresponding to the higher priority of the PUSCH and the PUCCH multiplexed with it, wherein the priority value of the PUCCH is the same as described in Embodiment 1 above, and will not be repeated here.

[0459] Example 3: When the time domain resources of the sensing RS and the uplink signal SRS overlap, the following signal transmission rules are used during the overlapping time:

[0460] 1. When no priority value is defined for the sensing RS, at least one of the following must be included:

[0461] Send Sensing RS, but not SRS;

[0462] Send SRS, but do not send sensing RS;

[0463] The signal transmission rules are determined based on the transmission methods of Sensing RS and SRS, and the priority rules in Table 4 are defined.

[0464] Table 4

[0465] 2. When a priority value is defined for the sensing RS, and the SRS is an aperiodic SRS transmission triggered by the DCI format of the scheduling data (including DCI formats 0_0 / 0_1 / 0_2 / 10 / 1_1 / 1_2), the priority value of the triggered aperiodic SRS can be determined according to the priority field in the DCI.

[0466] In some embodiments, the priority values ​​of the sensing RS and SRS are compared, and the signal corresponding to the higher priority is sent, while the signal corresponding to the lower priority is not sent (the smaller the priority value, the higher the priority).

[0467] In some embodiments, if the priority values ​​of sensingRS and SRS are equal, the signal to be transmitted is determined according to the first transmission rule of embodiment 3 described above.

[0468] Example 4: If there is an overlap in the time domain resources of Sensing RS and PRACH, then the following signal transmission rules shall be used for the overlapping time:

[0469] 1. Send Sensing RS, but do not send PRACH;

[0470] 2. Send PRACH, but do not send sensing RS;

[0471] 3. Determine the signal transmission rules based on the transmission method of the sensing RS, and define the priority rules in Table 5.

[0473] In some embodiments, the priority values ​​of the uplink channel or signal are defined as shown in Table 6:

Alternatively, another apparatus is provided that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0477] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an Application-Specific Integrated Circuit (ASIC), and the functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), which can include a large number of logic gates.

In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a Graphics Processing Unit (GPU) (which can be understood as a microprocessor), or a Digital Signal Processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an Application-Specific Integrated Circuit (ASIC) or a Programmable Logic Device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. In addition, it can also be hardware circuits designed for artificial intelligence, which can be understood as ASICs, such as Neural Network Processing Units (NPUs), Tensor Processing Units (TPUs), and Deep Learning Processing Units (DPUs).
