Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus of a user equipment (UE) may receive, from a base station, a physical downlink control channel (PDCCH) indicating a configuration for one or more of demodulation reference signal (DMRS) bundling that is to be used for channel estimation by the base station for a first group of physical uplink control channels (PUCCHs) or frequency hopping for a second group of PUCCHs. The apparatus may transmit, to the base station, one or more PUCCHs based at least in part on the configuration. 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 receive, from a base station, an indication that indicates whether a common search space (CSS) is associated with a first type of physical downlink control channel (PDCCH) or a second type of PDCCH. The first type of PDCCH may correspond to a cell-broadcast PDCCH and the second type of PDCCH may correspond to a UE-specific PDCCH. The CSS may be for downlink control information (DCI) with a cyclic redundancy check scrambled by a group radio network temporary identifier (G-RNTI) that schedules a multicast and broadcast service (MBS). The UE may receive, from the base station, the first type of PDCCH or the second type of PDCCH. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit a plurality of physical downlink control channel (PDCCH) communications in a same PDCCH monitoring occasion in a first cell, and may transmit a plurality of physical downlink shared channel (PDSCH) communications in at least one of the first cell or a second cell. Each of the PDCCH communications schedules a respective PDSCH communication of the plurality of PDSCH communications. A PDCCH communication, of the plurality of PDCCH communications, includes an indication of a counter downlink assignment index that is based at least in part on a combination of a starting symbol and a cell in which an associated PDSCH communication is to be transmitted, a cell index of the cell in which the associated PDSCH communication is to be transmitted, and the PDCCH monitoring occasion. Numerous other aspects are provided.

Abstract: Aspects described herein relate to determining a failure associated with reception, by a base station, of an initial transmission of a random access message transmitted by the UE in a two-step random access procedure, and based on determining the failure situations associated with reception of the random access message, configuring the parameters of a retransmission and/or retransmitting at least a portion of the random access message.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may receive an indication of an uplink transmission timing pattern configuration for transmitting uplink transmissions on a first carrier. The UE may identify to use both the first carrier and a second carrier during a single uplink transmission mode, where the UE may transition between sending the uplink transmissions on the first and second carriers. The UE may also determine, based on the uplink transmission timing pattern configuration, a timing of uplink carrier switching periods for retuning between transmissions on the first carrier and on the second carrier. As a result, the UE may transmit, during the single uplink transmission mode, on both the first carrier and the second carrier in accordance with the uplink transmission timing pattern configuration for the first carrier and the uplink carrier switching periods.

Abstract: Certain aspects of the present disclosure provide techniques for uplink scheduling for communication on an uplink from a user equipment (UE) to a base station (BS). The uplink scheduling is based on uplink transmission (UL Tx) switching time and/or uplink data preparation time of the UE. The uplink data preparation time is calculated based on the UL Tx switching time. For example, a UE can report to a BS at least one of an indication of a UL Tx switching time and an uplink data preparation time of the UE. In return, the UE can receive an indication of uplink scheduling from the BS, which the UE can use to communicate with the BS.

The apparatus may receive, from a base station, an indication of a plurality of transmission schedules for at least one of a plurality of PUSCHs or a plurality of PDSCHs, the indication including a time gap prior to a transmission of each of the plurality of PUSCHs or each of the plurality of PDSCHs. The apparatus may also receive, from the base station, DCI identifying at least one transmission schedule for at least one PUSCH of the plurality of PUSCHs or at least one PDSCH of the plurality of PDSCHs. Further, the apparatus may transmit, to the base station, the at least one PUSCH or receive, from the base station, the at least one PDSCH based on the at least one transmission schedule in the received DCI.
