[0026] The following describes in detail the transmission decision method, device, terminal, network side device and storage medium provided in the embodiments of the present application according to several embodiments and application scenarios with reference to the drawings.

[0027] Please refer to Fig. 2, which is a flowchart of the transmission decision method provided in the embodiment of the present application. As shown in Fig. 2, it includes the following steps 201 and 202.

[0028] In step 201, a terminal receives first signaling, the first signaling being for determining an uplink transmission operation in a first TRP of the terminal.

[0029] The first signaling may be a first signaling received by the terminal and transmitted from a network side device, for example, the first signaling may be: may be carried by at least one of a Radio Resource Control (RRC) message, a Downlink Control Information (DCI), a configured grant message, or a Medium Access Control (MAC CE) message; Here, the RRC signaling may include a cell-specific RRC message or a UE-specific RRC message, and the DCI may include a scheduling DCI, an activation DCI, or a group-common DCI.

[0030] The above-mentioned first signaling for determining the uplink transmission operation in the first TRP of the terminal may mean that the first signaling explicitly or implicitly indicates the uplink transmission operation in the first TRP of the terminal.

[0031] The uplink transmission operation may include transmitting uplink transmission in the first TRP of the terminal, for example, transmitting a physical uplink shared channel (PUSCH) in the first TRP of the terminal or transmitting a physical uplink control channel (PUCCH) in the first TRP of the terminal, or the uplink transmission operation may include not transmitting uplink transmission in the first TRP of the terminal, for example, not transmitting a PUSCH in the first TRP of the terminal or not transmitting a PUCCH in the first TRP of the terminal.

[0032] The first TRP is the TRP in which the uplink transmission is located in the MTRP.

[0033] In step 202, if there is an overlapping time domain resource between the uplink transmission in the first TRP of the terminal and the downlink transmission in the second TRP of the terminal, the terminal determines an uplink transmission operation in the first TRP of the terminal based on the first signaling; Here, the terminal is connected to a plurality of TRPs, and the plurality of TRPs includes the first TRP and the second TRP.

[0034] The existence of overlapping time domain resources between the uplink transmission in the first TRP of the terminal and the downlink transmission in the second TRP of the terminal may mean that there is partial or complete overlapping of time domain resources between the uplink transmission and the downlink transmission, such as an overlap in at least one code / time slot.

[0035] The above-mentioned terminal's determination of the uplink transmission operation in the first TRP of the terminal based on the first signaling may be to transmit an uplink transmission in the TRP of the terminal or not to transmit an uplink transmission in the TRP of the terminal. Wherein, when transmitting an uplink transmission in the TRP of the terminal, the terminal does not need to transmit a downlink transmission in the second TRP of the terminal; when not transmitting an uplink transmission in the TRP of the terminal, the terminal can transmit a downlink transmission in the second TRP of the terminal.

[0036] In the embodiment of the present application, the above steps can realize that when there is overlapping time domain resources between the uplink transmission in the first TRP of the terminal and the downlink transmission in the second TRP of the terminal, the uplink transmission operation in the first TRP of the terminal is determined based on the first signaling, thereby solving the collision problem of overlapping time domain resources in the first TRP and the second TRP of the terminal and further improving the transmission performance of the terminal.

[0037] In an alternative embodiment, the first signaling comprises: The information is for indicating at least one of priority information, instructions for handling resource overlap, a physical cell ID (PCI), and simultaneous uplink transmission using multiple antenna panels of the terminal.

[0038] The priority information may be used to indicate the priority of an uplink transmission, or the priority between an uplink and a downlink transmission, or the priority between signals, etc. For example, in some embodiments, the priority information may be Priority among multiple TRPs; Priority of uplink transmission; a priority between uplink and downlink transmissions; and a priority among a plurality of Synchronization Signal Block (SSB) lists, each of the plurality of SSB lists corresponding to a plurality of different PCIs, and each of the SSB lists corresponding to one TRP / TRP group.

[0039] The priority between the plurality of TRPs may be the priority between the plurality of TRPs in an MTRP scenario, and the priority of the uplink transmission may be the specific priority of the uplink transmission, for example, uplink transmission (PUSCH / PUCCH) is a high-priority transmission, and the priority between the uplink transmission and downlink transmission may be the priority between an uplink transmission channel / signal and a downlink transmission channel / signal, for example, the transmission priority between the uplink transmission (PUSCH / PUCCH) and SSB transmission.

[0040] The above-mentioned multiple SSB lists each corresponding to multiple different PCIs may mean that one SSB list corresponds to one PCI and multiple SSB lists correspond one-to-one to multiple PCIs, and the above-mentioned SSB list corresponding to one TRP / TRP group may mean that one TRP / TRP group corresponds to one SSB list and one TRP / TRP group corresponds to the same PCI.

[0041] Based on the priority information, the terminal can determine the uplink transmission operation in the first TRP of the terminal. For example, if the priority of the uplink transmission is higher than the downlink transmission, it decides to transmit the uplink transmission in the first TRP of the terminal; if the priority of the first TRP is higher than the second TRP, it decides to transmit the uplink transmission in the first TRP of the terminal; if the uplink transmission has a high priority, it decides to transmit the uplink transmission in the first TRP of the terminal; if the priority of the SSB list corresponding to the first TRP is higher than the SSB list corresponding to the second TRP, it decides to transmit the uplink transmission in the first TRP of the terminal; conversely, the terminal may not transmit the uplink transmission in the first TRP of the terminal.

[0042] The resource overlap processing instruction may be for instructing a specific processing operation in the terminal, and thus the terminal can determine the uplink transmission operation in the first TRP of the terminal according to the instruction. For example, in some embodiments, the resource overlap processing instruction may be used to instruct whether to perform code rate matching / rate matching on the physical downlink shared channel (PDSCH) when there is overlapping time domain resources between the PDSCH transmission in the first TRP and the SSB transmission in the second TRP. In this case, if code rate matching / rate matching is instructed on the PDSCH, the terminal does not transmit uplink transmission in the first TRP of the terminal, but instead transmits uplink transmission in the first TRP of the terminal.

[0043] It should be noted that the resource overlap processing instruction can also be used to indicate whether to perform code rate matching / rate matching for the PDSCH when there is overlapping time domain resources between the PDSCH transmission of a first TRP and the SSB transmission of another TRP, where the other TRP is one of the TRPs other than the first TRP in the MTRP, and the TRP and the first TRP may have the same or different PCI. Also, if the instruction indicates that PDSCH should be performed code rate matching / rate matching, then, when there is overlapping time domain resources between the uplink transmission of the first TRP and the downlink transmission of the second TRP, the UE determines not to transmit the uplink transmission of the first TRP of the UE, but rather to transmit the uplink transmission of the first TRP of the UE.

[0044] Here, the PDSCH may be a PDSCH that does not carry a System Information Block (SIB) 1, i.e., the PDSCH indicated by the resource overlap processing instruction does not include a PDSCH that carries an SIB 1.

[0045] The first signaling may explicitly or implicitly indicate a PCI, and may indicate the PCI of one or more TRPs. Thus, the terminal can determine the uplink transmission operation in the first TRP of the terminal based on the PCI indicated by the first signaling. For example, if the PCIs of the first TRP and the second TRP are different, the terminal transmits an uplink transmission in the first TRP, and if the PCIs of the first TRP and the second TRP are the same, the terminal does not transmit an uplink transmission in the first TRP.

[0046] Optionally, the first signaling comprises: a Transmission configuration indication (TCI) state or a TCI state list; The correspondence between TCI status and PCI, The PCI is indicated by at least one of the TCI state list and the PCI correspondence.

[0047] Here, the TCI status may be the TCI status of the first TRP, or the TCI status may be the TCI status of the second TRP, and the TCI status list may include at least one TCI status of the first TRP and the second TRP.

[0048] In some embodiments, the TCI status corresponds to a PCI of the first TRP, or the TCI status corresponds to a PCI of at least one TRP other than the first TRP among the plurality of TRPs; and / or The TCI state list includes at least one TCI state, and each TCI state corresponds to a PCI of at least one TRP.

[0049] Furthermore, when the terminal determines the corresponding PCI according to the TCI status, the terminal can further determine a TRP having the same PCI as the first TRP in combination with the correspondence between PCIs and TRPs known to the terminal. For example, assuming that the network indicates that the PCI corresponding to TRP#1 is 5 according to the TCI status in the DCI, if the terminal can obtain the mapping / correspondence between each TRP and PCI in the MTRP through RRC configuration and determine that the PCI corresponding to TRP#2 is also 5, the terminal determines that TRP#1 and TRP#2 have the same PCI.

[0050] The PCI corresponding to one or more TCI states included in the TCI state list is the PCI of a TRP among the plurality of TRPs, and one TCI state can correspond to the PCI of one or more TRPs.

[0051] In this embodiment, the PCI of the TRP is determined according to the TCI status. Of course, the first signaling may be used to set the PCI of some TRPs, and the PCI of the remaining TRPs may be determined through other routes, such as pre-setting.

[0052] In some embodiments, the terminal may further determine to transmit an uplink transmission in the first TRP of the terminal, or may determine not to transmit an uplink transmission in the first TRP of the terminal, based on an instruction to simultaneously perform uplink transmission on multiple antenna panels of the terminal.

[0053] It should be noted that some of the priority information, processing instructions in the event of resource overlap, PCI, and simultaneous uplink transmission from multiple antenna panels of the terminal indicated by the first signaling may be stipulated in the protocol or pre-configured on the network side.

[0054] In an alternative embodiment, the uplink transmission operation comprises: transmitting an uplink transmission of the first TRP; and not transmitting an uplink transmission of the first TRP.

[0055] The above-mentioned transmitting the uplink transmission of the first TRP may be transmitting the uplink transmission of the first TRP in overlapping time domain resources, i.e., the UE may transmit the uplink transmission to the TRP in overlapping time domain resources.

[0056] The above-mentioned not transmitting the uplink transmission of the first TRP may mean not transmitting the uplink transmission of the first TRP in the overlapping time domain resource, i.e., the terminal may not transmit the uplink transmission to the TRP in the overlapping time domain resource.

[0057] In this embodiment, if there is an overlapping time domain resource, the uplink transmission of the first TRP may always be transmitted, or the uplink transmission of the first TRP may always not be transmitted, i.e., other conditions may not be taken into consideration, or the decision to transmit the uplink transmission of the first TRP or not to transmit the uplink transmission of the first TRP may be made in combination with other conditions.

[0058] optionally, transmitting an uplink transmission of the first TRP if the content indicated by the first signaling satisfies a first condition; and / or If the content indicated by the first signaling satisfies a second condition, the uplink transmission of the first TRP is not transmitted.

[0059] Here, the first and second conditions are pre-set conditions or conditions agreed upon in the protocol.

[0060] In some embodiments, if the first signaling is for indicating at least one of priority information, a handling instruction when a resource overlap occurs, a physical cell identifier PCI, and simultaneous uplink transmission using multiple antenna panels of the terminal, The first condition is the priority information indicating that the first TRP has the highest priority; the priority information indicating that the priority of uplink transmission of the first TRP is higher than the priority of downlink transmission of the second TRP; the priority information indicating that uplink transmission is of high priority; The processing instruction in the case of resource overlap is for instructing not to perform code rate matching / rate matching on the PDSCH when there is overlapping time domain resources between the PDSCH transmission of the first TRP and the SSB transmission of the second TRP; The first TRP and the second TRP have different PCIs; The priority information may include at least one of: indicating that a priority of the SSB list of the first TRP is higher than a priority of the SSB list of the second TRP.

[0061] The above-mentioned priority information indicating that the first TRP has the highest priority may be indicating that the first TRP has the highest priority among multiple TRPs connected to the terminal.

[0062] The above-mentioned priority information indicating that the uplink transmission has a high priority may be the priority information indicating that the uplink transmission has a predefined high priority.

[0063] In some embodiments, if the first signaling is for indicating at least one of priority information, a handling instruction when a resource overlap occurs, a physical cell identifier PCI, and simultaneous uplink transmission using multiple antenna panels of the terminal, The second condition is: the priority information indicating that the priority of uplink transmission of the first TRP is not higher than the priority of downlink transmission of the second TRP; the priority information indicating that downlink transmission is of high priority; The resource overlap processing instruction is for instructing to perform code rate matching / rate matching on the PDSCH when there is overlapping time domain resources between the PDSCH transmission of the first TRP and the SSB transmission of the second TRP; The first TRP and the second TRP have the same PCI; The first TRP and the second TRP are in the same cell and have different PCIs; The priority information may include at least one of: indicating that the priority of the SSB list of the first TRP is not higher than the priority of the SSB list of the second TRP.

[0064] The above-mentioned priority information indicating that the downlink transmission has a high priority may be that the priority information indicates that the downlink transmission has a predefined high priority. 。

[0065] above In accordance with the first and second conditions, When the first TRP and the second TRP are in the same cell but have different PCIs, if the uplink transmission in the first TRP and the SSB transmission in the second TRP overlap in the time domain, the uplink transmission in the first TRP is not performed; If the first signaling indicates that a first TRP has the highest transmission priority, always transmit the uplink transmission in the first TRP when there is an overlap between an uplink transmission in the first TRP and a downlink transmission in a second TRP, and further, always transmit the uplink transmission in the first TRP when there is an overlap between an uplink transmission in the first TRP and an SSB transmission in the second TRP; If the first signaling indicates that the uplink transmission priority is higher than the SSB transmission, or indicates that the uplink transmission is a high-priority transmission, then if there is an overlap between the uplink transmission in the first TRP and the SSB transmission in the second TRP, always transmit the uplink transmission in the first TRP; otherwise, do not transmit the uplink transmission in the first TRP; If the first signaling indicates that code rate matching / rate matching is to be performed when PDSCH transmission in the first TRP and SSB transmission in the second TRP overlap, if there is an overlap between uplink transmission in the first TRP and SSB transmission in the second TRP, not perform uplink transmission in the first TRP; otherwise, determine whether to perform uplink transmission in the first TRP according to priority; If the second TRP is another TRP in the MTRP that has the same PCI as the first TRP, and there is an overlap between the uplink transmission in the first TRP and the SSB transmission in the second TRP, the uplink transmission in the first TRP is not performed; If the second TRP is another TRP in the MTRP that has a PCI different from that of the first TRP, and there is an overlap between the uplink transmission in the first TRP and the SSB transmission in the second TRP, transmitting the uplink transmission in the first TRP; When an SSB transmission in the second TRP overlaps with an uplink transmission in the first TRP, if the priority defined in the SSB list corresponding to the second TRP is lower than the priority defined in the SSB list corresponding to the first TRP, transmit the uplink transmission in the first TRP; When SSB transmission in the second TRP overlaps with uplink transmission in the first TRP, if the priority defined in the SSB list corresponding to the second TRP is not lower than the priority defined in the SSB list corresponding to the first TRP, at least one of the following can be realized: not performing uplink transmission in the first TRP, and transmitting the SSB that overlaps with the uplink transmission.

[0066] In some embodiments, the terminal determining the uplink transmission operation based on the PCI may be determining the uplink transmission operation based on the PCI when the terminal is equipped with multiple antenna panels.

[0067] In an optional embodiment, not transmitting an uplink transmission of the first TRP may include: The uplink transmission of the first TRP is discarded / canceled / ignored; receiving a downlink transmission of the second TRP; If the uplink transmission of the first TRP is a repetition transmission, counting the number of repetitions for the time slot in which the overlapping time domain resource exists, or not counting the number of repetitions for the time slot in which the overlapping time domain resource exists; If the uplink transmission of the first TRP is a Transport Block over multiple slots (TBoMS), counting transmission timing / time slots for the time slot in which the overlapping time domain resource exists, or not counting transmission timing / time slots for the time slot in which the overlapping time domain resource exists; and determining the time slot in which the overlapping time domain resource is located as an unavailable time slot if the terminal is configured for repeated transmission counted based on available time slots.

[0068] Here, the above-mentioned receiving downlink transmission of the second TRP may be receiving SSB transmission in the second TRP.

[0069] Whether or not to count the number of repetitions for the time slot in which the overlapping time domain resource exists can be determined by protocol agreement or pre-setting.

[0070] As mentioned above, whether to count transmission timing / time slots for the time slots in which the overlapping time domain resources are located or not can be determined specifically by protocol agreement or pre-setting.

[0071] Determining the time slot in which the overlapping time domain resource is located as an unavailable time slot may involve not transmitting uplink transmission in the unavailable time slot and not counting the number of repetitions.

[0100] Optionally, the method further comprises: The network side device further includes receiving capability information reported by the terminal, and the capability information includes: Whether the terminal supports counting based on available time slots; and whether the terminal has the capability to transmit on multiple panels simultaneously.

[0101] It should be noted that this embodiment is an embodiment of a network side device corresponding to the embodiment shown in Fig. 2, and for specific embodiments, reference can be made to the relevant description of the embodiment shown in Fig. 2. In order to avoid repetition, detailed descriptions will be omitted in this embodiment.

[0102] In the following, the method provided in the embodiment of the present application will be described by taking the example that the downlink transmission is SSB transmission and the uplink transmission is PUSCH transmission.

[0103] Example 1 Assuming that the priority of SSB transmission set by default in the network is higher than PUSCH transmission, if a terminal is scheduled to perform PUSCH repetition type A transmission in TRP#1 and the number of repetitions is eight, and if there is an overlap between the transmission timing of the third repetition transmission and the SSB transmission timing in TRP#2, the terminal will not transmit PUSCH repetition type A transmission in TRP#1 and will receive SSB transmission in TRP#2 at this transmission timing.

[0104] Furthermore, although the terminal does not transmit PUSCH repetition type A transmission in TRP#1, the time slot in which this transmission timing exists must be counted in the number of repetitions of repetition type A. Or, if the network configures / enables a method in which the terminal counts based on available time slots in the PUSCH repetition type A transmission, this transmission timing is regarded as an unavailable time slot and is not counted in the number of repetitions; Alternatively, if the network configures / enables a method in which the terminal counts the PUSCH repetition type A transmission based on available time slots, this transmission timing is regarded as an available time slot and counted in the number of repetitions, but the third repetition transmission is not actually performed.

[0105] Example 2 Assuming that the network sets the priority among multiple TRPs as TRP#1>TRP#2>TRP#4>TRP#3 by RRC, if a terminal is scheduled to perform PUSCH repetition type A transmission in TRP#1 and the number of repetitions is 8, and if there is an overlap between the transmission timing of the third repetition transmission and the SSB transmission timing in TRP#2, the terminal will transmit PUSCH repetition type A transmission in TRP#1 according to the priority order among the TRPs.

[0106] Example 3 It is assumed that the network sets the priority among multiple TRPs as TRP#1>TRP#2>TRP#4>TRP#3 by RRC, and also sets the priority among uplink transmissions and SSB transmissions as SSB>PUSCH by system messages.

[0107] In this case, if the terminal is scheduled to perform PUSCH repetition type A transmission in TRP#1 and the number of repetitions is 8, and if there is an overlap between the transmission timing of the third repetition and the SSB transmission timing in TRP#2, the terminal's transmission operation will be as follows.

[0108] According to the TRP priority, the terminal transmits PUSCH repetition type A transmission in TRP #1, Alternatively, depending on the priority of the channel / signal, the terminal does not transmit PUSCH repetition type A transmission in TRP#1, and receives SSB transmission in TRP#2 at this transmission timing; Alternatively, if TRP#1 and TRP#2 have the same PCI, according to the priority of the channel / signal, the terminal does not transmit PUSCH repetition type A transmission in TRP#1, and receives SSB transmission in TRP#2 at this transmission timing; Alternatively, if TRP#1 and TRP#2 have the same PCI, the terminal transmits PUSCH repetition type A transmission in TRP#1 according to the TRP priority; Alternatively, if TRP#1 and TRP#2 have different PCIs, the terminal transmits PUSCH repetition type A transmission in TRP#1 according to the TRP priority; Alternatively, if TRP#1 and TRP#2 have different PCIs, depending on the priority of the channel / signal, the terminal does not transmit PUSCH repetition type A transmission in TRP#1, and receives SSB transmission in TRP#2 at this transmission timing.

[0109] Example 4 Assuming that the network indicates that the PCI corresponding to TRP#1 is 5 based on the TCI status in the DCI, if the terminal can determine that the PCI corresponding to TRP#2 is also 5 based on the mapping / correspondence between each TRP and PCI in the MTRP configured by RRC, the terminal can know that TRP#1 and TRP#2 have the same PCI.

[0110] At this time, if the UE is scheduled to perform PUSCH repetition type A transmission in TRP#1 and the number of repetitions is 8, if there is an overlap between the transmission timing of the third repetition transmission and the SSB transmission timing in TRP#2, The UE does not transmit PUSCH repetition type A transmission in TRP#1, and receives SSB transmission in TRP#2 at this transmission timing.

[0111] Furthermore, if the network configures / enables a method in which the UE counts the PUSCH repetition type A transmission based on available time slots, this transmission timing will be regarded as an unavailable time slot and will not be counted in the number of repetitions.

[0112] Example 5 Assuming that the network indicates through the TCI status list in the DCI that the PCI corresponding to TRP#1 is 5 and the PCI corresponding to TRP#2 is 8, the terminal can know that TRP#1 and TRP#2 have different PCIs. In addition, the network sets the priority of SSB transmission to be higher than the priority of PUSCH transmission.

[0113] In this case, if the UE is scheduled to perform PUSCH repetition type A transmission in TRP#1 and the number of repetitions is eight, and there is an overlap between the transmission timing of the third repetition transmission and the SSB transmission timing in TRP#2, the terminal will not transmit PUSCH repetition type A transmission in TRP#1 and will receive SSB transmission in TRP#2 at this transmission timing.

[0114] Alternatively, if the network configures / enables a method in which the terminal counts the PUSCH repetition type A transmission based on available time slots, this transmission timing is regarded as an available time slot and counted in the number of repetitions, but the third repetition transmission is not actually performed.
