Abstract: Apparatus, methods, and computer-readable media for wideband uplink control channel capability indication during initial access are disclosed herein. A user equipment (UE) may transmit an uplink message indicating an uplink resource bandwidth capability of a physical uplink control channel (PUCCH) of the UE based on a power spectral density (PSD) limitation and a maximum transmission power of the UE. The UE may receive a downlink message indicating an uplink resource allocation of the PUCCH corresponding to the uplink resource bandwidth capability. Alternatively, the UE may receive a downlink configuration that indicates a first set of uplink resources and a second set of uplink resources. The UE may transmit an acknowledgment message in response to a downlink message of a random access channel process. The acknowledgment message includes the uplink resource bandwidth capability that indicates a selection between the first set of uplink resources and the second set of uplink resources.

Abstract: Aspects of methods, computer-readable mediums, and apparatuses are provided for a user equipment (UE) or a base station. The UE receives, from a base station, an indication to transmit a scheduling request (SR). The UE receives a downlink transmission triggering hybrid automatic repeat request (HARQ) feedback in one or more physical uplink control channel (PUCCH) resources. The UE transmits the SR to the base station in the one or more PUCCH resources for the HARQ feedback. The base station transmits, to a UE, an indication to transmit an SR. The base station transmits a downlink transmission triggering HARQ feedback in one or more PUCCH resources. The base station receives the SR from the UE in the one or more PUCCH resources.

Abstract: Certain aspects of the present disclosure provide techniques for a method for wireless communication by a user-equipment (UE). The method generally includes receiving, on a control channel, a configuration for an uplink control information (UCI) repetition, determining, in dependence on the control channel, whether to prioritize transmission of the UCI repetition over other uplink signaling, wherein a scheduled resource for transmission of the UCI repetition overlaps with resources for the other uplink signaling, and taking one or more actions associated with communication of the UCI repetition in accordance with the determination.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit an indication of a physical downlink control channel (PDCCH) monitoring capability that indicates an amount of time between two consecutive PDCCH monitoring windows, a number of slots to be included in a PDCCH monitoring window, and a number of consecutive symbols in a slot to be associated with PDCCH monitoring. The UE may receive a PDCCH monitoring configuration that is based at least in part on the PDCCH monitoring capability. Numerous other aspects are described.

Abstract: A user equipment may be configured to perform UE indication to temporarily suspend report occasions. In some aspects, the user equipment may receive, from a base station, out-of-cell reporting configuration including an out-of-cell reporting parameter for reporting layer one (L1) channel information for an out-of-cell beam. Further, the user equipment may send, to the base station for beam selection in consideration of simultaneous access to another base station based on the out-of-cell reporting parameter, the L1 channel information for the out-of-cell beam.

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, a broadcast message associated with initial access. The UE may monitor, for an additional message from the base station, a set of monitoring occasions that are non-consecutive across slots, based at least in part on the broadcast message. In some aspects, the set of monitoring occasions are non-consecutive across slots based at least in part on a stored rule that uses a subcarrier spacing. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for demodulation reference signal (DMRS) sequence selection. One aspect provides a method for wireless communication by a first wireless node. The method generally includes selecting a type of DMRS sequence to be used for communication with a second wireless node based on a signal quality associated with the communication, receiving a message having the type of DMRS sequence, and performing channel estimation based on the DMRS sequence using the message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may switch from a first group of search space sets for monitoring a physical downlink control channel (PDCCH) to an empty group of search space sets. The UE may refrain from monitoring the PDCCH based at least in part on switching to the empty group. In some aspects, the UE may switch from a first group of PDCCH search space sets to at least one dormant group of PDCCH search space sets identified in configuration information. The UE may also process one or more PDCCH search space sets of the at least one dormant group of PDCCH search space sets based at least in part on the received configuration information. Numerous other aspects are provided.

Abstract: A method for wireless communication by a user equipment (UE) determines a downlink/uplink (DL/UL) switching capability of the UE, and reports the DL/UL switching capability to a network. The DL/UL switching capability may indicate a quantity of DL/UL switch points, N, supported by the UE, and a time duration to which the quantity of DL/UL switch points is applied. The DL/UL switching capability may indicate a minimum link duration for which the UE should maintain a link direction after a previous DL/UL switch operation and before a next DL/UL switch operation. The DL/UL switching capability may include a DL/UL switching delay indicating a time specified for the UE to complete a DL/UL switching operation. The DL/UL switching capability may be based on a reference subcarrier spacing (SCS).
