Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may select, on a sidelink of a user equipment (UE), a channel for sidelink-assisted feedback to be transmitted by the UE, wherein the sidelink-assisted feedback is associated with uplink control information (UCI) or aperiodic channel state information feedback; and transmit, to the UE, an indication of a resource allocation associated with the selected channel for the sidelink-assisted feedback. Numerous other aspects are provided.

Abstract: Aspects described herein relate to transmitting a first random access message in a random access procedure based on whether beam refinement is configured. In an aspect, it can be determined whether a base station uses beam refinement for receiving a first random access message in a two-step random access procedure. Based on whether the base station uses beam refinement, one or more parameters for transmitting the first random access message can be determined, and the first random access message can be transmitted to the base station and based on the one or more parameters.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for beam refinement via physical random access channel (PRACH) repetition. A method that may be performed by a network entity includes determining resources to monitor for a PRACH transmission sent from a user equipment (UE) as part of a random access channel (RACH) procedure, performing receive beam sweeping when receiving PRACH repetitions sent using the determined resources, using results of the receive beam sweeping to refine one or more beams and to select a refined beam of the refined one or more beams, and using the selected refined beam for at least one of receiving a subsequent message from the UE as part of the RACH procedure or sending a subsequent message to the UE as part of the RACH procedure.

Abstract: This disclosure provides methods, devices and systems for random access procedures and beam refinement for wireless communications. A base station may repeat a transmission of a random access message 2 to a user equipment (UE) on a plurality of physical downlink control channel (PDDCH) candidates to improve reception of the random access message 2 and provide for selection of a refined beam. The UE may receive the random access message 2 on the plurality of repeated PDCCH candidates during a random access response window. The UE may select an offset based on a strongest of the plurality of PDCCH candidates. The UE may transmit a random access message 3 on resources indicated by the random access message 2 that are time shifted by the offset. The base station may select a beam for transmitting a random access message 4 based on the offset.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information indicating a master cell group (MCG) maximum power value and a secondary cell group (SCG) maximum power value. The UE may determine whether a combination of the maximum power values satisfies a threshold. The UE may perform a transmission on the SCG using a first transmit power and a transmission on the MCG using a second transmit power, wherein, based on the combination of the MCG maximum power value and the SCG maximum power value satisfying the threshold, the first transmit power is determined based on a time offset, or wherein, based on the combination of the MCG maximum power value and the SCG maximum power value failing to satisfy the threshold, the first transmit power is determined without using the time offset. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a deadline prior to a first uplink transmission associated with a secondary cell group (SCG), wherein the first uplink transmission is associated with a first priority level; determine whether to perform a second uplink transmission associated with a master cell group (MCG), wherein the second uplink transmission is initiated after the deadline, and wherein the second uplink transmission is associated with a second priority level; and adjust a transmit power of the first uplink transmission based at least in part on at least one of: determining whether to perform the second uplink transmission, or the first priority level and the second priority level. 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 transmit, to a base station (BS), a UE capability indicator of a capability of the UE. The BS may select an uplink switch mode. The UE may receive, from the BS, signaling identifying the uplink switch mode, of a plurality of uplink switch modes, for switching one or more transmit chains of the UE between a first uplink duplex configuration and a second uplink duplex configuration. The UE may switch at least one uplink duplex configuration of at least one transmit chain of the UE based at least in part on the uplink switch mode. Numerous other aspects are provided.

Abstract: Aspects described herein relate to indicating search spaces and/or control information formats for receiving multicast/broadcast service (MBS) downlink control information (DCI). A device can receive a search space configuration defining one or more search spaces for detecting communications intended for a group of one or more user equipment (UEs), determine a priority for detecting control information transmitted over a control channel based on the one or more search spaces, and perform, based on the priority, detection for the control information over the control channel based on the one or more search spaces and/or the other defined search spaces.

Abstract: Certain aspects of the present disclosure propose techniques for transmission time interval (TTI) bundling for physical downlink shared channel (PDSCH) in long term evolution (LTE). According to certain aspects a method is provided for wireless communications. The method may be performed, for example, by a user equipment (UE). The method generally includes identifying a transmit time interval (TTI) bundle comprising a subset of subframes from a set of subframes for transmitting data on a physical downlink shared channel (PDSCH) and receiving the data on the PDSCH in the subset of subframes.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a set of modulations for a random access message associated with a two-step random access channel (RACH) procedure. The set of modulations may be either a first set of modulations or a second set of modulations that is different from the first set of modulations. The set of modulations may be determined based at least in part on whether a signal strength satisfies a signal strength threshold. The UE may transmit the random access message based at least in part on the determined set of modulations. The random access message may include a physical uplink shared channel modulated using the determined set of modulations. Numerous other aspects are provided.
