[0023] The disclosed technology provides implementations and examples of a simultaneous uplink transmission scheme in wireless communications.

[0024] In the current 5G NR system, due to the limitation of UE capability, uplink transmission can only be performed in a non-overlapping manner in the time domain. Once downlink transmission based on multiple TRPs can be supported, this will become a bottleneck for the throughput of the entire system. Accordingly, some restrictions on uplink transmission are specified to ensure the capabilities of single-panel UEs, such as the discarding rules for uplink control information (UCI) multiplexing, the omission of channel state information (CSI) reporting, and CSI piggyback on PUSCH. At the same time, with the evolution of mobile communication technology, UE can be equipped with multiple panels to implement simultaneous uplink transmission in order to achieve higher throughput in the future.

[0025] Simultaneous uplink transmission in multiple transmit and receive point (MTRP) operation can improve the throughput of uplink data transmission. Various embodiments of the disclosed technology provide some methods and details to support such enhancement through simultaneous uplink schemes for UE side and gNB side.

[0026] 5G NR includes many MIMO features that help utilize a large number of antenna units of the base station for frequency bands below 6 GHz (frequency range 1, FR1) and above 6 GHz (frequency range 2, FR2). In addition, one of the MIMO features is support for multi-TRP operation. The key point of this function is to collaborate with multiple TRPs to send data to or receive data from the UE, thereby improving transmission performance. Since NR is in the process of commercialization, various aspects that need further enhancement can be found from actual deployment scenarios. According to the current evolution of 5G NR in 3GPP, in MTRP operation, multi-panel UE can support and perform simultaneous uplink transmission, which is conducive to improving the throughput of uplink transmission.

[0027] Note that in this patent document, a "simultaneous uplink transmission scheme" refers to multiple uplink transmissions that can be fully or partially overlapped in the time domain. Simultaneous uplink transmissions can be associated with different panels / TRP IDs. A simultaneous uplink transmission scheme includes at least one of the following scenarios.

[0047] Overview

[0048] In some embodiments, if at least one condition is met, the UE performs simultaneous uplink transmission from different panels (e.g., two panels) to different TRP / CC / UL (e.g., two TRP / CC / UL).

[0049] In the following example situations, at least one of the conditions may be met:

[0050] - Determine the simultaneous uplink transmission scheme to the UE. The indication may be made explicitly or implicitly and corresponds to at least one of a Radio Resource Control (RRC), a Medium Access Control (MAC) Control Element (CE), or a DCI. The indication shall refer to Figure 1 To reference Figures 1 to 9 The simultaneous uplink transmission scheme among those described is discussed.

[0051] The first uplink signal and the second uplink signal completely or partially overlap in the time domain.

[0052] -The first information associated with the first uplink signal is different from the first information associated with the second uplink signal. The first information may include at least one of a panel index or a TRP index. The first information is used to identify the panel of the UE that sends the uplink signal or the TRP that receives the uplink signal.

[0055] In some embodiments, the simultaneous transmission scheme may be explicitly or implicitly indicated by control signaling, wherein the control signaling is provided by at least one of RRC, MAC CE, or DCI. In some embodiments, the time unit of the overlapping portion of the first uplink signal and the second uplink signal in the time domain may be at least one of a sub-symbol, a symbol, a time slot, a sub-frame, a frame, or a transmission opportunity.

[0056] In some embodiments, "the first / second / third information associated with the first uplink signal is different from the first / second / third information associated with the second uplink signal" includes at least one of the following: 1) first information (e.g., TRP index or panel index) that can be explicitly or implicitly indicated by RRC, MAC CE or DCI, 2) control information (e.g., DCI) of the first uplink signal can be the same as or different from the control information of the second uplink signal, 3) the priority of UCI report carried on the first uplink signal is different from the priority of UCI report carried on the second uplink signal, 4) the type of UCI report carried on the first uplink signal is different from the type of UCI report carried on the second uplink signal, 5) the content of the first uplink signal (e.g., UCI report, control data, user data, transport block or codeword) is different from the content of the second uplink signal.

[0057] Implementation 1: Overlap between two physical channels reported for UCI with different priorities

[0058] The following cases discuss the scenario where two physical channels with different priorities overlap. In each case, the corresponding operation is performed depending on whether a simultaneous uplink transmission scheme is provided. As discussed in the above overview, a simultaneous uplink transmission scheme is provided when at least one specific condition is met.

[0059] Case 1

[0060] If the transmission of a first PUCCH with a larger priority index scheduled by the first DCI format in the first PDCCH reception completely or partially overlaps in time with a second PUSCH with a smaller priority index or a repetition of a second PUCCH transmission, the UE determines that PUCCH and / or PUSCH transmissions of different priority indices overlap, including repetitions (if any).

[0061] If no simultaneous uplink transmission scheme is provided, the UE first resolves the overlap of PUCCH and / or PUSCH transmissions of smaller priority indexes. In this case, the UE cancels the repetition (one or more) of the second PUSCH or second PUCCH transmission before the first symbol overlapping with the first PUCCH transmission.

[0062] If a simultaneous uplink transmission scheme is provided, the UE may transmit a first PUCCH of a larger priority index scheduled by a first DCI format in a first PDCCH reception, and a second PUSCH of a smaller priority index or (one or more) repetitions of a second PUCCH transmission. In this case, the first PUCCH is associated with a first panel / TRP / CC / uplink index, and the second PUSCH or (one or more) repetitions of a second PUCCH are associated with a second panel / TRP / CC / uplink index.

[0063] Case 2

[0064] If the transmission of a first PUSCH with a larger priority index scheduled by the first DCI format in the first PDCCH reception completely or partially overlaps in time with the repetition of the transmission of a second PUCCH with a smaller priority index, the UE determines that PUCCH and / or PUSCH transmissions of different priority indices overlap, including repetitions (if any).

[0065] If a simultaneous uplink transmission scheme is not provided, the UE cancels repetition of the second PUCCH transmission before the first symbol that will overlap with the first PUSCH transmission.

[0066] If a simultaneous uplink transmission scheme is provided, the UE sends a transmission of a first PUSCH with a larger priority index and a repetition of a transmission of a second PUCCH with a smaller priority index scheduled by the DCI format in the PDCCH reception. In this case, the first PUSCH is associated with the first panel / TRP / CC / uplink index, and the (one or more) repetitions of the second PUCCH transmission are associated with the second panel / TRP / CC / uplink index.

[0067] Case 3

[0068] The UE transmits certain channels, including repetitions that overlap completely or partially in time (if any). The certain channels include at least one of the following:

[0069] - A first PUCCH with a larger priority index of a Scheduling Request (SR), and a second PUCCH or PUSCH with a smaller priority index;

[0070] - A first PUCCH having a larger priority index for HARQ-ACK information received only in response to (one or more) PDSCHs without corresponding (one or more) PDCCHs, and a second PUCCH having a smaller priority index for HARQ-ACK information received only in response to (one or more) PDSCHs without corresponding (one or more) PDCCHs; or, a second PUCCH with a smaller priority index for SR and / or CSI; or, a configuration grant PUSCH with a smaller priority index; or, a PUSCH with (one or more) SP-CSI reporting without a smaller priority index for the corresponding PDCCH;

[0071] - PUSCH with a larger priority index for SP-CSI(s) reporting without a corresponding PDCCH, and PUCCH with a smaller priority index for SR or CSI or HARQ-ACK information received only in response to PDSCH(s) without a corresponding PDCCH(s); or

[0072] - A larger priority index is configured to grant PUSCH and a smaller priority index is configured to grant PUSCH on the same serving cell.

[0073] When the UE sends at least one of the above channels, the following operations are performed according to whether a simultaneous uplink transmission solution is provided.

[0074] In the absence of a simultaneous uplink transmission scheme, if the repetition of PUCCH / PUSCH transmission with a smaller priority index overlaps in time with the PUCCH / PUSCH transmission with a larger priority index, the UE is expected to cancel the repetition of the PUCCH / PUSCH transmission with the smaller priority index before the first symbol that overlaps with the PUCCH / PUSCH transmission with the larger priority index.

[0075] If a simultaneous uplink transmission scheme is provided, the UE sends a first PUCCH / PUSCH transmission with a larger priority index and a repetition of a second PUCCH / PUSCH transmission with a smaller priority index. In this case, the first PUCCH / PUSCH transmission is associated with a first panel / TRP / CC / uplink index, and the (one or more) repetitions of the second PUCCH / PUSCH transmission are associated with a second panel / TRP / CC / uplink index.

[0076] Case 4

[0077] If a simultaneous uplink transmission scheme is not provided, it is expected that the UE will not be scheduled to send a PUCCH or PUSCH with a smaller priority index that overlaps in time with a PUCCH with a larger priority index, which has HARQ-ACK information received only in response to a PDSCH without a corresponding PDCCH.

[0078] If a simultaneous uplink transmission scheme is provided, the UE sends a first PUCCH with HARQ-ACK information received only in response to a PDSCH without a corresponding PDCCH and a larger priority index, and a second PUCCH / PUSCH transmission with a smaller priority index. In this case, the first PUCCH transmission is associated with a first panel / TRP / CC / uplink index, and (one or more) repetitions of the second PUCCH / PUSCH transmission are associated with a second panel / TRP / CC / uplink index.

[0079] Case 5

[0080] If no simultaneous uplink transmission scheme is provided, it is expected that a UE will not be scheduled to send a PUCCH of a smaller priority index which would overlap in time with a PUSCH of a larger priority index with (one or more) SP-CSI reports but without a corresponding PDCCH.

[0081] If a simultaneous uplink transmission scheme is provided, the UE sends a first PUSCH with a larger priority index and a second PUCCH with a smaller priority index with (one or more) SP-CSI reports without corresponding PDCCH. In this case, the first PUSCH transmission is associated with the first panel / TRP / CC / uplink index, and the (one or more) repetitions of the second PUCCH are associated with the second panel / TRP / CC / uplink index.

[0082] Case 6

[0083] The multi-CSI-PUCCH-ResourceList is not provided to the UE. Resources for PUCCH transmission with HARQ-ACK information in response to SPS PDSCH reception and / or resources for PUCCH associated with SR occasions overlap in time with two resources for corresponding PUCCH transmissions with two CSI reports, and there are no resources for PUCCH transmission with HARQ-ACK information in response to detecting a DCI format that overlap in time with any previous resources.

[0084] If no simultaneous uplink transmission scheme is provided, the pseudo code causes the UE to attempt to determine a single PUCCH resource from the HARQ-ACK and / or SR resources and the two PUCCH resources with CSI reporting. The UE multiplexes the HARQ-ACK information and / or SR in the resources used for the PUCCH transmission with the higher priority CSI reporting, and does not transmit the PUCCH with the lower priority CSI reporting.

[0085] If a simultaneous uplink transmission scheme is provided, the UE sends HARQ-ACK information and / or SR with a CSI report with a higher priority in a resource used for a first PUCCH transmission, and sends a CSI report with a lower priority in another resource used for a second PUCCH transmission. The first PUCCH resource is determined by the result of a pseudo code from the HARQ-ACK and / or SR resources and the two PUCCH resources with CSI reports. In this case, the first PUCCH transmission is associated with a first panel / TRP / CC / uplink index, and the second PUCCH transmission is associated with a second panel / TRP / CC / uplink index.

[0086] Case 7

[0087] The UE sends a first PUCCH on more than one time slot and sends at least a second PUCCH on one or more time slots, and the transmissions of the first PUCCH and the second PUCCH will overlap in multiple time slots, then for each time slot in the multiple time slots, the UCI type priority is HARQ-ACK>SR>CSI with higher priority>CSI with lower priority. Therefore, UCI reporting with HARQ-ACK takes precedence over UCI reporting with SR, UCI reporting with SR takes precedence over UCI reporting with {CSI with higher priority}, and UCI reporting with {CSI with higher priority} takes precedence over UCI reporting with {CSI with lower priority}.

[0088] If a simultaneous uplink transmission scheme is not provided, the UE does not expect the first PUCCH and any second PUCCH to start at the same time slot and include a UCI type with the same priority. If the first PUCCH and any second PUCCH include a UCI type with the same priority, the UE sends the PUCCH starting at the earlier time slot and does not send the PUCCH starting at the later time slot. If the first PUCCH and any second PUCCH do not include a UCI type with the same priority, the UE sends the PUCCH including the UCI type with a higher priority and does not send the PUCCH including the UCI type with a lower priority.

[0089] If a simultaneous uplink transmission scheme is provided, the UE sends a first PUCCH and any second PUCCH starting in the same timeslot and including a UCI type with the same priority. In this case, the first PUCCH is associated with the first panel / TRP ID, and the second PUCCH is associated with the second panel / TRP / CC / uplink index. If the first PUCCH and any second PUCCH include a UCI type with the same priority, the UE sends the first PUCCH and any second PUCCH regardless of which starts in an earlier timeslot. In this case, the first PUCCH is associated with the first panel / TRP ID, and the second PUCCH is associated with the second panel / TRP / CC / uplink index. If the first PUCCH and any second PUCCH do not include a UCI type with the same priority, the UE sends a PUCCH including a UCI type with a higher priority and a PUCCH including a UCI type with a lower priority. In this case, the first PUCCH is associated with the first panel / TRP / CC / uplink index, and the second PUCCH is associated with the second panel / TRP / CC / uplink index.

[0090] Case 8

[0091] If any CSI report consists of two parts, the CSI report is transmitted on the PUCCH.

[0092] If no simultaneous uplink transmission scheme is provided, the UE may omit a portion of the second part of the CSI. The omission of the second part of the CSI is based on a priority order determined from the Prii,CSI(y,k,c,s) values. The second part of the CSI is omitted starting from the lowest priority level until the second part of the CSI code rate is less than or equal to the code rate configured by the higher layer parameter maxCodeRate.

[0093] If a simultaneous uplink transmission scheme is provided, the UE sends the first part of CSI in the first PUCCH and the second part of CSI in the second PUCCH. In this case, the first PUCCH is associated with the first panel / TRP / CC / uplink index, and the second PUCCH is associated with the second panel / TRP / CC / uplink index.

[0094] Case 9

[0095] The UE is configured to transmit two (in the time domain) colliding CSI reports for aperiodic CSI and SP CSI reported on PUSCH.

[0096] If no simultaneous uplink transmission scheme is provided, the UE shall not send iCSIThe CSI reporting of the (y, k, c, s) value is performed, or two CSI reports are multiplexed or one of them is discarded based on the priority value.

[0097] If a simultaneous uplink transmission scheme is provided, the UE sends aperiodic CSI report in the first PUSCH and sends SP SCI report in the second PUSCH. In this case, the first PUCCH is associated with the first panel / TRP / CC / uplink index, and the second PUCCH is associated with the second panel / TRP / CC / uplink index.

[0098] Implementation 2: Overlap between two physical channels for different types of UCI reporting

[0099] The following cases discuss the case where two physical channels for different types of UCI reporting overlap. In each case, the corresponding operation is performed depending on whether a simultaneous uplink transmission scheme is provided.

[0100] Case 1

[0101] In some embodiments, if the parameter simultaneousHARQ-ACK-CSI is not provided to the UE, the UE needs to multiplex DL HARQ-ACK information with or without SR and (one or more) CSI reports in the same PUCCH.
