[0039] The following description, in conjunction with the accompanying drawings, details a transmission determination method, apparatus, terminal, network-side device, and storage medium provided in this application through some embodiments and application scenarios.

[0040] Please see Figure 2 , Figure 2 This is a flowchart of a transmission determination method provided in an embodiment of this application, such as... Figure 2 As shown, the steps include:

[0041] Step 201: The terminal receives a first signaling, which is used to determine the uplink transmission operation of the terminal in the first TRP.

[0042] The aforementioned first signaling can be the first signaling sent by the terminal to the network-side device. For example, the first signaling can be carried by at least one of the following:

[0043] Radio resource control (RRC) messages, downlink control information (DCI) messages, configured grant messages, and medium access control control element (MAC CE) messages;

[0044] The aforementioned RRC signaling may include: cell-specific RRC messages or UE-specific RRC messages, and the aforementioned DCI may include: scheduling DCI, activation DCI, or group-common DCI.

[0045] The aforementioned first signaling used to determine the uplink transmission operation of the terminal in the first TRP can be either an explicit or implicit instruction from the first signaling to the terminal to perform an uplink transmission operation in the first TRP.

[0046] The aforementioned uplink transmission operation may include: uplink transmission by the transmitting terminal in the first TRP, such as the physical uplink shared channel (PUSCH) of the transmitting terminal in the first TRP, or the physical uplink control channel (PUCCH) of the transmitting terminal in the first TRP; or, the aforementioned uplink transmission operation may include: not transmitting the uplink transmission of the terminal in the first TRP, such as not transmitting the PUSCH of the terminal in the first TRP, or not transmitting the PUCCH of the terminal in the first TRP.

[0047] The first TRP mentioned above is the TRP where the uplink transmission is located in the MTRP.

[0048] Step 202: When there is an overlap in time domain resources between the uplink transmission of the terminal in the first TRP and the downlink transmission of the terminal in the second TRP, the terminal determines the uplink transmission operation of the terminal in the first TRP according to the first signaling.

[0049] The terminal connects to multiple TRPs, including the first TRP and the second TRP.

[0050] The overlapping time domain resources between the uplink transmission of the terminal in the first TRP and the downlink transmission of the terminal in the second TRP may be that the uplink transmission and the downlink transmission have partial or complete overlap in time domain resources, for example, at least one symbol / time slot overlaps.

[0051] According to the first signaling, the terminal determines that its uplink transmission operation in the first TRP can be either transmitting the terminal's uplink transmission in the TRP or not transmitting the terminal's uplink transmission in the TRP. Specifically, if the terminal transmits its uplink transmission in the TRP, it may not transmit its downlink transmission in the second TRP; if it does not transmit its uplink transmission in the TRP, it may transmit its downlink transmission in the second TRP.

[0052] In this embodiment of the application, the above steps can be used to determine the uplink transmission operation of the terminal in the first TRP according to the first signaling when there are overlapping time domain resources between the uplink transmission of the terminal in the first TRP and the downlink transmission of the terminal in the second TRP, so as to resolve the conflict problem of overlapping time domain resources of the terminal in the first TRP and the second TRP, thereby improving the transmission performance of the terminal.

[0053] As an optional implementation, the first signaling is used to indicate at least one of the following:

[0054] Priority information, resource overlap handling instructions, Physical Cell ID (PCI), and uplink transmission are performed simultaneously on multiple antenna panels of the terminal.

[0055] The aforementioned priority information can be used to indicate the priority of uplink transmission, the priority between uplink and downlink transmission, or the priority between signals, etc. For example, in some implementations, the aforementioned priority information may include at least one of the following:

[0056] Priority among multiple TRPs;

[0057] Uplink transmission priority;

[0058] Priority between uplink and downlink transmissions;

[0059] Priority among multiple Synchronization Signal Block (SSB) lists, wherein each SSB list corresponds to a different PCI, and any SSB list corresponds to a TRP / TRP group.

[0060] The priority among the aforementioned multiple TRPs can be the priority among multiple TRPs in an MTRP scenario; the priority of the aforementioned uplink transmission can be the specific priority of uplink transmission, such as uplink transmission (PUSCH / PUCCH) being a high-priority transmission; the priority between the aforementioned uplink transmission and downlink transmission can be the priority between the uplink transmission channel / signal and the downlink transmission channel / signal, such as the transmission priority between uplink transmission (PUSCH / PUCCH) and SSB transmission.

[0061] The above multiple SSB lists can correspond to multiple different PCIs, such as one SSB list corresponding to one PCI, multiple SSB lists corresponding to multiple PCIs one-to-one, and any one of the above SSB lists corresponding to one TRP / TRP group. Alternatively, one TRP / TRP group can correspond to one SSB list, or one TRP / TRP group can correspond to the same PCI.

[0062] Based on the aforementioned priority information, the terminal can determine its uplink transmission operation in the first TRP. For example, if the uplink transmission priority is higher than the downlink transmission priority, the terminal is determined to transmit uplink data in the first TRP. If the priority of the first TRP is higher than that of the second TRP, the terminal is determined to transmit uplink data in the first TRP. If the uplink transmission has a high priority, the terminal is determined to transmit uplink data in the first TRP. If the priority of the SSB list corresponding to the first TRP is higher than that of the SSB list corresponding to the second TRP, the terminal is determined to transmit uplink data in the first TRP. Conversely, the terminal may choose not to transmit uplink data in the first TRP.

[0063] The aforementioned resource overlap handling indication can be used to indicate specific processing operations at the terminal, allowing the terminal to determine its uplink transmission operation on the first TRP. For example, in some embodiments, the resource overlap handling indication can be used to indicate whether to perform rate-matching on the PDSCH when there are overlapping time-domain resources between the Physical Downlink Shared Channel (PDSCH) transmission of the first TRP and the SSB transmission of the second TRP. If rate-matching is indicated for the PDSCH in this case, the terminal's uplink transmission on the first TRP will not be transmitted; otherwise, the terminal's uplink transmission on the first TRP will be transmitted.

[0064] It should be noted that the above-mentioned resource overlap handling indication can also be used to indicate whether to perform rate-matching on the PDSCH when the PDSCH transmission of the first TRP overlaps with the SSB transmission of other TRPs in the time domain. Here, the other TRPs are one of the other TRPs in the MTRP besides the first TRP, and this TRP may have the same PCI or a different PCI as the first TRP. Furthermore, under this indication, if rate-matching / rate-matching is indicated for the PDSCH, then correspondingly, if the uplink transmission of the first TRP overlaps with the downlink transmission of the second TRP in the time domain, the uplink transmission of the terminal on the first TRP will not be transmitted; otherwise, the uplink transmission of the terminal on the first TRP will be determined to be transmitted.

[0065] The aforementioned PDSCH may be a PDSCH that does not carry System Information Block (SIB) 1, that is, the PDSCH indicated by the above resource overlap processing instruction does not include the PDSCH carrying SIB 1.

[0066] The aforementioned first signaling can explicitly or implicitly indicate the PCI, and can indicate the PCI of one or more TRPs. In this way, the terminal can determine the uplink transmission operation of the terminal in the first TRP based on the PCI indicated by the first signaling. If the PCI of the first TRP is different from that of the second TRP, the terminal transmits the uplink transmission in the first TRP. If the PCI of the first TRP is the same as that of the second TRP, the terminal does not transmit the uplink transmission in the first TRP.

[0067] Optionally, the first signaling indicates PCI via at least one of the following:

[0068] Transmission configuration indication (TCI) status, or a list of TCI statuses;

[0069] The correspondence between TCI status and PCI;

[0070] The correspondence between TCI status lists and PCI.

[0071] The aforementioned TCI state can be either the TCI state of the first TRP or the TCI state of the second TRP. The list of TCI states can include the TCI state of at least one of the first and second TRPs.

[0072] In some implementations, the TCI state corresponds to the PCI of the first TRP, or the TCI state corresponds to the PCI of at least one of the plurality of TRPs other than the first TRP; and / or

[0073] The TCI status list includes at least one TCI status, and each TCI status corresponds to at least one PCI of a TRP.

[0074] Furthermore, when a terminal determines the corresponding PCI through the TCI status, it can also combine the known correspondence between PCIs and TRPs to determine the TRP with the same PCI as the first TRP. For example, assuming the network indicates that the PCI corresponding to TRP#1 is 5 through 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, then it is determined that TRP#1 and TRP#2 have the same PCI.

[0075] The PCI corresponding to one or more TCI states in the above TCI state list is the PCI of the TRP among the above TRPs, and one TCI state can correspond to the PCI of one or more TRPs.

[0076] In this implementation, the PCI of the TRP is determined by the TCI status. Of course, the first signaling mentioned above can configure the PCI of some TRPs, while the PCI of other TRPs can be determined by other means, such as pre-configuration.

[0077] In some implementations, the terminal may also determine whether to transmit the uplink transmission of the transmitting terminal in the first TRP or not to transmit the uplink transmission of the transmitting terminal in the first TRP based on an indication that uplink transmission is being performed simultaneously on multiple antenna panels of the terminal.

[0078] It should be noted that the priority information, resource overlap processing instructions, PCI, and the part of the simultaneous uplink transmission of multiple antenna panels on the terminal mentioned above can also be agreed upon by the protocol or pre-configured by the network side.

[0079] As an optional implementation, the uplink transmission operation includes one of the following:

[0080] Transmit the uplink transmission of the first TRP;

[0081] The uplink transmission of the first TRP is not transmitted.

[0082] The aforementioned transmission of the first TRP uplink can be transmitted on overlapping time domain resources, that is, the terminal sends the uplink transmission to the TRP on overlapping time domain resources.

[0083] The aforementioned failure to transmit the uplink transmission of the first TRP can be achieved by not transmitting the uplink transmission of the first TRP on overlapping time domain resources, that is, the terminal does not send uplink transmissions to the TRP on overlapping time domain resources.

[0084] In this implementation, the uplink transmission of the first TRP may always be transmitted when overlapping time-domain resources exist, or the uplink transmission of the first TRP may never be transmitted, i.e., other conditions are not considered. Alternatively, other conditions may be considered to determine whether to transmit or not transmit the uplink transmission of the first TRP.

[0085] Optionally, if the content indicated by the first signaling satisfies the first condition, the uplink transmission of the first TRP is transmitted; and / or

[0086] If the content indicated by the first signaling satisfies the second condition, the uplink transmission of the first TRP will not be transmitted.

[0087] Among them, the first and second conditions mentioned above are pre-configured conditions or conditions agreed upon in the agreement.

[0088] In some implementations, when the first signaling is used to indicate at least one of priority information, resource overlap processing indication, physical cell identifier (PCI), or simultaneous uplink transmission from multiple antenna panels of the terminal:

[0089] The first condition may include at least one of the following:

[0090] The priority information indicates that the first TRP has the highest priority;

[0091] The priority information indicates that the uplink transmission priority of the first TRP is higher than the downlink transmission priority of the second TRP;

[0092] The priority information indicates that the uplink transmission is of high priority;

[0093] The resource overlap handling instruction is used to indicate that when there are overlapping time domain resources between the PDSCH transmission of the first TRP and the SSB transmission of the second TRP, rate matching / rate matching of the PDSCH is not performed.

[0094] The first TRP and the second TRP have different PCIs;

[0095] The priority information indicates that the priority of the SSB list of the first TRP is higher than the priority of the SSB list of the second TRP.

[0096] The aforementioned priority information indicates that the first TRP has the highest priority, which may mean that the first TRP has the highest priority among the multiple TRPs connected to the terminal.

[0097] The aforementioned priority information indicating that the uplink transmission is of high priority can be either a predefined high priority or a priority information indicating that the uplink transmission is of high priority.

[0098] In some implementations, when the first signaling is used to indicate at least one of priority information, resource overlap processing indication, physical cell identifier (PCI), or simultaneous uplink transmission from multiple antenna panels of the terminal:

[0099] The second condition may include at least one of the following:

[0100] The priority information indicates that the priority of the uplink transmission of the first TRP is not higher than the priority of the downlink transmission of the second TRP;

[0101] The priority information indicates that the downlink transmission is of high priority;

[0102] The resource overlap processing instruction is used to indicate that when there are overlapping time domain resources between the PDSCH transmission of the first TRP and the SSB transmission of the second TRP, the PDSCH should be rate-matched / rate-matched.

[0103] The first TRP and the second TRP have the same PCI;

[0104] The first TRP and the second TRP are in the same cell and have different PCIs;

[0105] The priority information indicates 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.

[0106] The aforementioned priority information indicating that the downlink transmission is of high priority can be interpreted as indicating that the downlink transmission is of a predefined high priority.

[0107] At least one of the following can be achieved by fulfilling the first and second conditions mentioned above:

[0108] If the first TRP and the second TRP are in the same cell but have different PCIs, and the uplink transmission on the first TRP overlaps with the SSB transmission on the second TRP in the time domain, then the uplink transmission on the first TRP will not be performed.

[0109] If the first signaling indicates that the first TRP has the highest transmission priority, then when there is an overlap between the uplink transmission on the first TRP and the downlink transmission on the second TRP, the uplink transmission on the first TRP will always be transmitted; furthermore, when there is an overlap between the uplink transmission on the first TRP and the SSB transmission on the second TRP, the uplink transmission on the first TRP will always be transmitted.

[0110] 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 when the uplink transmission on the first TRP overlaps with the SSB transmission on the second TRP, the uplink transmission on the first TRP will always be transmitted; otherwise, the uplink transmission on the first TRP will not be performed.

[0111] If the first signaling indicates that rate-matching will be performed when the PDSCH transmission on the first TRP overlaps with the SSB transmission on the second TRP, then when the uplink transmission on the first TRP overlaps with the SSB transmission on the second TRP, the uplink transmission on the first TRP will not be performed; otherwise, the uplink transmission on the first TRP will be performed according to priority.

[0112] If the second TRP is another TRP in the MTRP that has the same PCI as the first TRP, then when the uplink transmission on the first TRP overlaps with the SSB transmission on the second TRP, the uplink transmission on the first TRP will not be performed.

[0113] If the second TRP is another TRP in the MTRP that has a different PCI from the first TRP, when the uplink transmission on the first TRP overlaps with the SSB transmission on the first TRP, the uplink transmission on the first TRP is transmitted.

[0114] When the SSB on the second TRP overlaps with the uplink transmission of 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, the uplink transmission on the first TRP is transmitted.

[0115] When the SSB on the second TRP overlaps with the uplink transmission of 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, the uplink transmission on the first TRP will not be performed, and the SSB that overlaps with the uplink transmission will be transmitted.

[0116] In some implementations, when the terminal determines the uplink transmission operation based on the PCI, it may be in the case that the terminal has multiple antenna panels, and the uplink transmission operation is determined based on the PCI.

[0117] As an optional implementation, the non-transmission of the uplink transmission of the first TRP includes at least one of the following:

[0118] The uplink transmission of the first TRP was dropped / cancelled / ignored;

[0119] Receive downlink transmissions from the second TRP;

[0120] If the uplink transmission of the first TRP is a repetition transmission, the repetition count is performed on the time slot where the overlapping time domain resource is located, or the repetition count is not performed on the time slot where the overlapping time domain resource is located.

[0121] In the case that the uplink transmission of the first TRP is a Transport Block over multipleslots (TBoMS), the transmission timing / slot count is performed on the slot where the overlapping time domain resources are located, or the transmission timing / slot count is not performed on the slot where the overlapping time domain resources are located.

[0122] When the terminal is configured to perform repeated transmissions based on the available time slot count, the time slot containing the overlapping time domain resource is determined to be an unavailable time slot.

[0123] Wherein, receiving the downlink transmission of the second TRP may be receiving the SSB transmission on the second TRP.

[0124] Whether or not to count the number of repetitions in the time slot where the overlapping time domain resources are located can be determined by the protocol agreement or pre-configuration.

[0125] Whether to perform transmission timing / time slot counting or not for the time slots containing the aforementioned overlapping time domain resources can be determined by protocol agreement or pre-configuration.

[0126] Determining the time slot where the overlapping time domain resource is located as an unavailable time slot can be done by not transmitting uplink data and not counting the number of repetitions in the unavailable time slot.

[0127] As an optional implementation, when the first signaling is used to indicate PCI: based on the uplink and downlink frame structure configured by the SSB transmission of the first TRP, the SSB transmission of the third TRP, and the uplink and downlink parameters, as well as the time slot resource information corresponding to the uplink transmission of the first TRP, it is determined whether the time slot where the uplink transmission of the first TRP is located is an available time slot.

[0128] The third TRP is at least one of the plurality of TRPs that has the same PCI as the first TRP.

[0129] The uplink and downlink frame structures configured with the aforementioned higher-layer parameters may include the following:

[0130] Time Division Duplex Uplink-Downlink Common Configuration (tdd-UL-DL-ConfigurationCommon);

[0132] The SSB transmission of the first TRP mentioned above is determined by the following parameters:

[0133] The synchronization signal block on the first TRP is located at the burst concentration (ssb-PositionsInBurst);

[0134] The SSB transmission of the third TRP mentioned above is determined by the following parameter: the position of the synchronization signal block on the third TRP in the burst set (ssb-PositionsInBurst).

[0135] The ssb-PositionsInBurst on the first TRP and the ssb-PositionsInBurst on the third TRP can be the same parameter or different parameters.

[0136] The time-domain resource information corresponding to the uplink transmission of the first TRP mentioned above may include at least one of the following:

[0137] The uplink transmission of the first TRP corresponds to the Time Domain Resource Assignment (TDRA) information;

[0138] The time-domain resource allocation information in the configured grant corresponding to the uplink transmission of the first TRP.

[0139] The resources occupied by the uplink transmission of the first TRP in the time domain can be determined by the time domain resource allocation in the TDRA or configuration authorization.

[0140] If the uplink transmission of the first TRP does not overlap in the time domain with the SSB transmission of the first TRP, the SSB transmission of the third TRP, and the downlink time slot determined by the uplink / downlink frame structure configured by higher-layer parameters, or the special time slot used for downlink transmission, then the time slot where the uplink transmission of the first TRP is located is determined to be an available time slot; otherwise, it is determined to be an unavailable time slot.

[0141] In this embodiment, the uplink and downlink frame structures configured by the SSB transmission of the first TRP, the SSB transmission of the third TRP, and the time domain resource information corresponding to the uplink transmission of the first TRP are used to determine whether the uplink transmission time slot of the first TRP is an available time slot, thereby determining the number of repetitions based on the available or unavailable time slots.

[0142] As one possible implementation, the downlink transmission described above includes: SSB transmission.

[0143] In some implementations, the downlink transmission described above can also be other downlink transmissions besides SSB, such as PDSCH, PDCCH, etc.

[0144] As one possible implementation, the uplink transmission includes at least one of the following:

[0145] PUSCH repeated transmission;

[0146] TBoMS uplink transmission;

[0147] PUSCH retransmission based on TBoMS;

[0148] PUCCH is transmitted repeatedly.

[0149] The PUSCH-related transports mentioned above can be configured with either a configurable grant (CG) or a dynamic grant (DG).

[0150] The aforementioned repeated PUSCH transmissions may include at least one of the following:

[0151] The types of PUSCH repetition include: Type 1 PUSCH repetition, Type 2 PUSCH repetition, Message 3 (Msg3) PUSCH repetition, and PUSCH repetition based on RAR scheduling in non-contention-based random CFRA (Repetition of PUSCH scheduled by RAR in CFRA). Specifically, Type 1 PUSCH repetition is based on the number of consecutive timeslot repetitions, and Type 2 PUSCH repetition is based on the number of available timeslot repetitions.

[0152] The first type of PUSCH repetition can include at least one of the PUSCH repetition type A and PUSCH repetition type B defined by the protocol, and the second type of PUSCH repetition can include at least one of the PUSCH repetition type A and PUSCH repetition type B defined by the protocol.

[0154] The terminal reports capability information, which indicates at least one of the following:

[0155] Does the terminal support counting based on available time slots?

[0156] Does the terminal have the ability to transmit data simultaneously across multiple panels?

[0157] In this embodiment, the aforementioned capability information enables the network-side device to configure the corresponding first signaling for the terminal, so that the uplink transmission operation of the terminal indicated by the first signaling in the TRP matches the terminal's capabilities, thereby further improving the terminal's transmission performance.

[0158] In this embodiment, the terminal receives a first signaling message, which is used to determine the uplink transmission operation of the terminal at a first transmit / receive point (TRP). When there is overlap in time domain resources between the uplink transmission at the first TRP and the downlink transmission at a second TRP, the terminal determines its uplink transmission operation at the first TRP based on the first signaling message. The terminal connects to multiple TRPs, including the first TRP and the second TRP. This allows the terminal to determine its uplink transmission operation at the first TRP based on the first signaling message when there is overlap in time domain resources between the uplink transmission at the first TRP and the downlink transmission at the second TRP, thus resolving the conflict problem of overlapping time domain resources between the first and second TRPs and improving the terminal's transmission performance.

[0159] Please see Figure 3 , Figure 3 This is a flowchart of a transmission determination method provided in an embodiment of this application, such as... Figure 3 As shown, it includes the following steps:

[0160] Step 301: The network-side device sends a first signaling to the terminal. The first signaling is used to determine the uplink transmission operation of the terminal in the first TRP when there is overlap in time domain resources between the uplink transmission of the terminal in the first TRP and the downlink transmission of the terminal in the second TRP.

[0181] Receive downlink transmissions from the second TRP;

[0182] If the uplink transmission of the first TRP is a repeated transmission, the number of repetitions in the time slot where the overlapping time domain resource is located is counted, or the number of repetitions in the time slot where the overlapping time domain resource is located is not counted.

[0183] When the uplink transmission of the first TRP is a multi-slot transport block (TBoMS), the transmission timing / slot count is performed on the slot where the overlapping time domain resources are located, or the transmission timing / slot count is not performed on the slot where the overlapping time domain resources are located.

[0184] When the terminal is configured to perform repeated transmissions based on the available time slot count, the time slot containing the overlapping time domain resource is determined to be an unavailable time slot.

[0185] Optionally, when the first signaling is used to indicate PCI: based on the uplink and downlink frame structure configured by the SSB transmission of the first TRP, the SSB transmission of the third TRP, and the time domain resource information corresponding to the uplink transmission of the first TRP, it is determined whether the time slot where the uplink transmission of the first TRP is located is an available time slot.

[0196] The network-side device receives capability information reported by the terminal, and the capability information is used to indicate at least one of the following:

[0197] Does the terminal support counting based on available time slots?

[0198] Does the terminal have the ability to transmit data simultaneously across multiple panels?

[0199] It should be noted that this embodiment is as a comparison with... Figure 2 The implementation methods of the network-side devices shown in the embodiments can be found in the following examples. Figure 2 To avoid repetition, the relevant descriptions of the embodiments shown will not be repeated in this embodiment.

[0200] The following example illustrates the method provided in this application: downstream transmission is SSB transmission, and upstream transmission is PUSCH transmission.

[0201] Example 1:

[0202] Assuming that the network default configuration prioritizes SSB transmission over PUSCH transmission, if the terminal is scheduled to perform PUSCH repetition type A transmission on TRP#1, with 8 repetitions, and if the timing of the 3rd repetition overlaps with the timing of SSB transmission on TRP#2, then the terminal will not transmit the PUSCH repetition type A transmission on TRP#1, and the terminal will receive the SSB transmission on TRP#2 at this transmission timing.

[0203] Furthermore, the terminal does not transmit PUSCH repetition type A transmissions on TRP#1, but the time slot in which this transmission occurs needs to be counted for the number of repetition type A repetitions.

[0204] Alternatively, if the network is configured / enabled to use a terminal-based available time slot counting method for this PUSCH repetition type A transmission, then this transmission opportunity is considered an unavailable time slot and is not counted in the repetition count;

[0205] Alternatively, if the network is configured / enabled to use a terminal-based available time slot counting method for this PUSCH repetition type A transmission, then this transmission opportunity is considered an available time slot and counted in the repetition count, but a third repetition transmission is not actually performed.

[0206] Example 2:

[0207] Assume the network configures the priority among multiple TRPs via RRC: TRP#1>TRP#2>TRP#4>TRP#3. If the terminal is scheduled to perform PUSCH repetition type A transmission on TRP#1, with 8 repetitions, and the transmission timing of the 3rd repetition overlaps with the SSB transmission timing on TRP#2, then according to the priority order among the TRPs, the terminal will transmit the PUSCH repetition type A transmission on TRP#1.

[0208] Example 3:

[0209] Assuming the network configures the priority between multiple TRPs via RRC: TRP#1>TRP#2>TRP#4>TRP#3, the network also configures the priority between uplink transmission and SSB transmission via system messages: SSB>PUSCH.

[0210] If the terminal is scheduled to perform a PUSCH repetition type A transmission on TRP#1 at this time, with 8 repetitions, and if the timing of the 3rd repetition overlaps with the timing of the SSB transmission on TRP#2, then the terminal's transmission operation is as follows:

[0211] Based on the TRP priority, the terminal transmits PUSCH repetition type A transmission on TRP#1;

[0212] Alternatively, depending on the channel / signal priority, the terminal may not transmit PUSCH repetition type A transmissions on TRP#1, but instead receive SSB transmissions on TRP#2 at the same transmission time.

[0213] Alternatively, if TRP#1 and TRP#2 have the same PCI, according to the channel / signal priority, the terminal does not transmit PUSCH repetition type A transmission on TRP#1, but instead receives SSB transmission on TRP#2 at the same transmission time.

[0214] Alternatively, if TRP#1 and TRP#2 have the same PCI, the terminal transmits PUSCH repetition type A transmission on TRP#1 according to the TRP priority;

[0215] Alternatively, if TRP#1 and TRP#2 have different PCIs, the terminal transmits PUSCH repetition type A transmission on TRP#1 according to the TRP priority;

[0216] Alternatively, if TRP#1 and TRP#2 have different PCIs, based on channel / signal priority, the terminal will not transmit PUSCH repetition type A transmissions on TRP#1, but will instead receive SSB transmissions on TRP#2 at the same transmission time.

[0217] Example 4:

[0218] Assuming the network indicates that the PCI corresponding to TRP#1 is 5 through the TCI status in the DCI, if the terminal can determine that the PCI corresponding to TRP#2 is also 5 through the mapping / correspondence between each TRP and PCI in the MTRP configured in the RRC, then the terminal can know that TRP#1 and TRP#2 have the same PCI.

[0219] If the UE is scheduled to perform a PUSCH repetition type A transmission on TRP#1 at this time, with a repetition count of 8 times, and the transmission timing of the 3rd repetition overlaps with the SSB transmission timing on TRP#2...

[0220] The UE will not transmit the PUSCH repetition type A transmission on TRP#1, but will instead receive the SSB transmission on TRP#2 at the same transmission time.

[0221] Furthermore, if the network has configured / enabled the UE to count available time slots in the PUSCH repetition type A transmission configuration, then this transmission opportunity is considered an unavailable time slot and is not counted in the repetition count.

[0222] Example 5:

[0223] Assuming 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, then the terminal can know that TRP#1 and TRP#2 have different PCIs. Additionally, the network is configured to prioritize SSB transmissions over PUSCH transmissions.

[0224] If the UE is scheduled to perform PUSCH repetition type A transmission on TRP#1 at this time, with a repetition count of 8 times, and if the transmission timing of the 3rd repetition overlaps with the SSB transmission timing on TRP#2, then the terminal will not transmit the PUSCH repetition type A transmission on TRP#1, but will instead receive the SSB transmission on TRP#2 at this transmission timing.

[0225] Alternatively, if the network is configured / enabled to count available time slots for the terminal in the PUSCH repetition type A transmission, then this transmission opportunity is considered an available time slot and counted in the repetition count, but a third repetition transmission is not actually performed.
