Abstract: Methods, systems, and devices for wireless communications at a user equipment (UE) are described. A UE may receive control signaling that indicates that the UE is scheduled to transmit a first uplink control channel message during first time domain resources and a first uplink shared channel message during second time domain resources, and the time domain resources may overlap. The UE may identify that the UE includes a UE capability to simultaneously transmit uplink control channel and uplink shared channel messages. The UE may transmit the first uplink control channel message the first component carrier during the first time domain resources and also the first uplink shared channel message during the second time domain resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication associated with Type B physical uplink channel repetitions of a transport block. The UE may transmit the repetitions of the transport block, including a first smaller repetition of the repetitions that has a first payload size that is smaller than a nominal payload size for the repetitions and that includes a first self-decodable data portion of the transport block. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communication systems, for example those supporting accumulated feedback, a user equipment (UE) may receive an indication of a plurality of accumulated feedback events that are each representative of different feedback combinations for reporting accumulated feedback for a set of scheduled downlink occasions and may determining the accumulated feedback for the set of scheduled downlink occasions. The UE may select, from the plurality of accumulated feedback events, a representative event based on the accumulated feedback and may transmit an uplink control message indicative of the representative event. In some examples, transmitting the uplink control message may include identifying a Huffman code for the representative event and transmitting the Huffman code via one or more stages of the uplink control message.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may monitor for one or more downlink transmissions from a base station based at least in part on a grant identifying resources for the one or more downlink transmissions. The UE may determine feedback information for each of the one or more downlink transmissions based at least in part on the monitoring. The UE may identify, based at least in part on the monitoring, one or more duplexing parameters to be requested to the base station for subsequent communications between the UE and the base station, the one or more duplexing parameters pertaining to operation of the UE in at least one of a full duplex communications mode or a half duplex communications mode. The UE may transmit a feedback message indicating the feedback information and the one or more duplexing parameters to the base station.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may monitor for semi-persistent scheduling (SPS) transmissions and generate SPS hybrid automatic repeat request (HARQ) bits scheduled for transmission to the base station in a set of uplink symbols. However, a collision may occur during transmission if a physical uplink control channel (PUCCH) carrying the SPS HARQ bits overlaps with downlink symbols. The UE may defer all SPS HARQ bits from collided PUCCHs to a next available PUCCH resource. In some examples, the UE may distribute deferred HARQ bits across multiple available PUCCH resources. The UE may distribute the deferred HARQ bits evenly across the next available PUCCH resources, or the UE may distribute the deferred HARQ bits unevenly according to a pattern. In some examples, the base station may indicate (e.g., via a downlink control information (DCI) message) a deferment pattern to the UE.

Abstract: A UE receives control signaling that indicates that the UE is scheduled to transmit one or more uplink control channel messages on a first component carrier that overlap in a time domain with one or more uplink shared channel messages scheduled for transmission on a second component carrier. The UE resolves a first overlap of uplink control channels having a same priority level, if present, and resolves, after resolving the first overlap, a second overlap of an uplink control channel and at least one uplink shared channel having the same priority level, if present. The UE resolves two or more channels having a different priority level after resolving the first overlap and the second overlap. The UE transmits one or more uplink transmissions including at least one of the one or more uplink control channel messages and the one or more uplink shared channel messages.

Abstract: Aspects relate to supporting power control for physical uplink control channel (PUCCH) transmissions on an uplink secondary component carrier (SCC) of a wireless communication system. In some aspects, a user equipment (UE) receives a power control configuration from a base station for use by the UE for a PUCCH transmission on a selected uplink SCC. The UE then transmits, based at least in part on the power control configuration, the PUCCH to the base station on the selected uplink SCC. Closed-loop and open-loop power control examples are provided. In some aspects, common or shared power control configurations are provided by the base station for use with each component carrier of a PUCCH group. In other aspects, carrier-specific power control configurations are provided by the base station.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to mechanisms for using block acknowledgments to acknowledge semi-persistently scheduled (SPS) occasions from multiple SPS configurations. An example method generally includes determining that a slot scheduled for reporting acknowledgment feedback for an SPS physical downlink shared channel (PDSCH) potentially overlaps with at least one downlink or flexible symbol, deciding whether to cancel or to delay reporting the acknowledgment feedback to a network entity based on one or more conditions, and canceling or delaying reporting the acknowledgment feedback to the network entity, in accordance with the decision.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a slot allocation to provide hybrid automatic repeat request (HARQ) acknowledgement (ACK) feedback to multiple transmission reception points (TRPs). For example, each TRP may be allocated at least one slot for HARQ-ACK feedback such that HARQ-ACK feedback for different TRPs may not be transmitted in a same slot. Additionally, the UE may determine a TRP-specific HARQ-ACK codebook for feedback transmissions to each TRP in their corresponding slots. In some cases, the UE may also determine TRP-specific uplink parameters for the feedback transmissions to each TRP. The UE may then transmit feedback to a TRP using a corresponding slot from the slot allocation and using the TRP-specific HARQ-ACK codebook and the TRP-specific uplink parameters.

Abstract: Aspects relate to configuring active groups of antenna ports. An apparatus may support different groups of antenna ports. One or more of these groups may be designated as active (e.g., for a scheduled transmission). In some examples, a first apparatus may send to a second apparatus an indication of the active groups. The second apparatus may then use the active groups for a transmission.
