Abstract: A central unit (CU) transmits synchronization timing information for a multicast broadcast service (MBS) single frequency network (SFN) data transmission in a synchronous manner to multiple distributed units (DUs). The CU transmits the MBS SFN data transmission to the multiple DUs for synchronous transmission to one or more user equipments (UEs). A DU receives synchronization timing information for a MBS SFN data transmission in a synchronous manner with at least one additional DU. The DU transmits the MBS SFN data transmission with a timing based on the synchronization timing information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive one or more of an indication of a set of timing offset values associated with a hybrid automatic repeat request acknowledgment (HARQ-ACK) codebook or information associated with a set of start and length indicator values (SLIVs) for candidate data channels associated with the HARQ-ACK codebook. The UE may transmit the HARQ-ACK codebook, the HARQ-ACK codebook being based at least in part on one or more of distinct values of the set of timing offset values or distinct values of the set of SLIVs. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may select, from a plurality of slot formats for supporting time division duplexing, a slot format for use during time division duplexing; transmit an information element that includes a half-slot slot-type to identify the slot format for use during time division duplexing; and communicate with a user equipment (UE) in a time division duplexing mode in accordance with the slot format. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, signaling that indicates a relative power difference between a first cell and a second cell. The UE may apply the relative power difference in a transmission occasion that includes at least a first uplink transmission on the first cell and a second uplink transmission on the second cell, wherein applying the relative power difference causes the first uplink transmission on the first cell to be transmitted at a lower power level than the second uplink transmission on the second cell. Numerous other aspects are described.

Abstract: Aspects presented herein may enable a base station to map one or more DMRSs to one or more REs of a slot based on the locations of one or more CRSs in the slot and/or based on whether at least one DMRS overlaps with at least one CRS. In one aspect, the base station maps PDCCH DMRS of a first RAT to a CORESET based on whether CRS of a second RAT overlaps at least partially with the CORESET. The base station transmits the PDCCH DMRS mapped to the CORESET.

Abstract: Support for hybrid automatic repeat request acknowledgment feedback for multiple multicast services in 5G new radio (NR) is provided. Resource allocation techniques are provided to allocate uplink control channel resource for acknowledgment of downlink multicast data transmissions associated with one or more multicast services. An apparatus, such a user equipment (UE), receives multicast data associated with one or more multicast services from a base station. The apparatus determines an uplink resource, such as a physical uplink control channel (PUCCH) resource, for transmitting multicast acknowledgement feedback, such as positive acknowledgement (ACK)/negative acknowledgement (NACK) feedback, in response to the received multicast data. The apparatus transmits the acknowledgement feedback for the one or more multicast services to the base station in the determined uplink resource.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a UE transmits a DSS capability indication to a network entity (e.g., base station), which determines scheduling information for resources of a DSS carrier based on the DSS capability indication. In another aspect, a BS transmits RAT-specific (e.g., LTE-specific) information associated with a DL RS (e.g., LTE CRS) to a UE, which processes the DL RS on a DSS carrier based at least in part on the RAT-specific information.

Abstract: Since multiple transmit-receive point (TRP) communications may increase the number of physical downlink control channel (PDCCH) candidates without increasing the number of cells, new limits for multi-TRP communications may be defined. A UE may determine a PDCCH monitoring capability across all downlink serving cells that may account for multiple-TRP cells and for carrier aggregation and dual connectivity using a multiplication factor for serving cells with two control resource set (CORESET) groups, for signaling a number representing PDCCH monitoring capability across all downlink serving cells. Further, the UE may determine limits of a number of serving cells based on the capability and a configuration of serving cells. The UE may determine a total limit and a per cell limit of PDCCH candidates and non-overlapped control channel elements (CCEs) to monitor in a slot for a cell group. The UE may perform blind decoding operations within the limits.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, for a plurality of carriers in a cross-carrier scheduling scenario, whether a quantity of downlink control information (DCI) sizes for a set of DCIs that the UE monitors satisfies a threshold, wherein the threshold is a per scheduling cell per scheduled cell threshold or a per scheduled cell threshold. The UE may selectively perform a DCI size alignment procedure to adjust a DCI size configuration based at least in part on whether the quantity of DCI sizes satisfies the threshold. The UE may monitor for the set of DCIs based at least in part on the DCI size configuration. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, for a secondary cell and a primary cell where cross-carrier scheduling is to occur from the secondary cell to the primary cell, whether a quantity of downlink control information (DCI) sizes for a set of DCIs that the UE monitors satisfies a threshold, wherein the threshold is a per scheduling cell per scheduled cell threshold or a per scheduled cell threshold. The UE may selectively perform a DCI size alignment procedure to adjust a DCI size configuration based at least in part on whether the quantity of DCI sizes satisfies the threshold. The UE may monitor for the set of DCIs based at least in part on the DCI size configuration. Numerous other aspects are provided.
