Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured with a mapping between downlink control information (DCI) codepoint values, multicast configurations, and unicast configurations. A DCI may then signal to the UE to apply one of a multicast configuration or a unicast configuration to receive a shared data channel transmission. For example, for a given DCI field of a group-common downlink control channel for multicast data, one or some DCI codepoint values may be associated with values configured for a multicast configuration, while remaining codepoints are associated with values configured for a unicast configuration. In some implementations, the UE may identify which multicast configuration or unicast configuration to apply based on the mapping, a type of data transmission scheduled by the DCI, specified values for the DCI codepoint values, whether the shared data channel transmission is a retransmission, or a combination thereof.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine a result associated with an initial set of transmissions of a periodic transmission cycle, and switch a search space configuration set to be used for one or more slots of the periodic transmission cycle based at least in part on the result, the search space configuration set being switched to a candidate search space configuration set. In some aspects, a user equipment may determine that a search space configuration set to be used for a slot of a periodic transmission cycle is to be switched based at least in part on a result associated with an initial set of transmissions of the periodic transmission cycle; and switch the search space configuration, the search space configuration set being switched to a candidate search space configuration set.

Abstract: In embodiments of systems and methods for managing control signaling for multicast communications, a base station may transmit to a wireless device an indication of whether to monitor a group common physical downlink control channel (GC PDCCH), a wireless device-specific PDCCH for multicast configuration information, or both. The base station may determine a schedule for transmitting multicast communications to the wireless device based on a capability reported by the wireless device, and may transmit to the wireless device an indication of whether a transport block for GC multicast communications including services for multicast communications will be scheduled by the GC PDCCH, the wireless device-specific PDCCH, or both. The base station may transmit, and the wireless device may receive, the multicast communications according to the multicast configuration information and the schedule.

Abstract: Methods, systems, and devices for wireless communication are described. In one example, a method for wireless communication at a user equipment (UE) includes identifying that the UE is in carrier aggregation communication with a first cell having a first sub-carrier spacing and a second cell having a second, different sub-carrier spacing. The method may further include monitoring one or more UE-specific search spaces of the first cell for first control information scheduling a first data communication on the first cell and one or more UE-specific search spaces of the first cell or the second cell for second control information scheduling a second data communication on the first cell, and resolving a scheduling order of the first control information scheduling the first data communication and the second control information scheduling the second data communication based at least in part on the monitoring and on a scheduling condition.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for performing rate matching for a physical downlink shared channel (PDSCH). An example method generally includes monitoring for at least first and second downlink control information (DCI) formats for scheduling a physical downlink shared channel (PDSCH), determining a bitwidth of a rate matching indicator field of at least one of the first DCI format or the second DCI format, and performing PDSCH rate matching for a PDSCH scheduled by a DCI of the first or second DCI format based, at least in part, on the rate matching indicator field in the DCI or a format of the DCI.

Abstract: A configuration to enable a UE to discard a TPC command for the MCG if there is an overlapping SCG transmission. The apparatus determines that a first PUSCH transmission to an SCG is scheduled to be at least partially concurrent in time with a second PUSCH transmission to a MCG. The apparatus determines whether to receive a TPC command associated with the transmission of the second PUSCH. The apparatus determines whether to discard the TPC command based on when the TPC command is received.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain a set of measurements related to a unicast service channel based at least in part on one or more reference signals associated with the unicast service channel and a set of measurements related to a multicast/broadcast service (MBS) channel based at least in part on one or more reference signals associated with the MBS channel. The UE may apply one or more communication parameters to ensure continuity for an MBS service. For example, in some aspects, the one or more communication parameters are based at least in part on the set of measurements related to the unicast service channel and the set of measurements related to the MBS channel. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure an outer coded block which a user equipment (UE) may implement to recover an unsuccessfully decoded transmission. The base station may send, to the UE, downlink control information (DCI) indicating an outer coding scheme for the group of data blocks (e.g., a first data block and a second data block). The UE may monitor for the data blocks and the outer coded block. The UE may decode the data blocks based on the outer coded block and the outer coding scheme. In some examples, the outer code block may be made up of a combination of the first and second data blocks. The UE may use the combination of the outer coded block and one of the data blocks to decode an unsuccessfully decode data block.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive signaling indicating a group of transmission configuration indicator states including a first subset associated with a first bandwidth part and a second subset associated with a common frequency resource. The UE may determine, based on the group of transmission configuration indicator states, a transmission configuration indicator state list arrangement indicating a first state list associated with the first bandwidth part and a second state list associated with the common frequency resource. The UE may select, based on the transmission configuration indicator state list arrangement, a transmission configuration indicator state sharing scheme or a transmission configuration indicator state separation scheme. The sharing scheme may include at least one transmission configuration indicator state that may be common between a unicast transmission configuration and a multicast transmission configuration.
