Abstract: In an aspect, a UE and BS perform a RACH procedure whereby a preamble sequence group for a preamble is associated with a downlink receive capability of the UE. In another aspect, a UE and BS perform a RACH procedure whereby a preamble sequence group is associated with a group-specific RA-RNTI that is used to scramble an associated DCI communication. In another aspect, UEs performing a RACH procedure with a BS via different sets of ROs may monitor the same GC-DCI scrambled with a common RA-RNTI. In another aspect, a UE and BS perform a 2-Step RACH procedure whereby a Msg-A payload includes information indicative of a downlink receive capability level associated with the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A group of random access channel opportunities are identified over which to transmit a preamble associated with a random access channel procedure. A preamble sequence group associated with the identified group of random access channel opportunities is determined based on a repetition level associated with the preamble sequence group. At least one downlink message associated with the random access channel procedure is received based on the repetition level.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may transmit a plurality of repetitions of a cell-common wakeup signal (WUS) on a different transmit beam in each monitoring occasion of one or more monitoring occasions. Another apparatus may beam sweep receive beams in each monitoring occasion to receive the cell-common WUS and to identify a transmit beam/receive beam pair for receiving a paging communication in a paging occasion associated with the transmit beam.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for indicating sidelink CSI information to a base station. A UE and a base station may determine a priority of a sidelink CSI report on an uplink channel in association with a priority of one or more of at least one uplink transmission or at least one other sidelink transmission. The sidelink CSI report may correspond to one or more sidelink transmissions between the UE and at least one other UE. The UE may transmit, and the base station may receive, via the uplink channel, the sidelink CSI report based on the priority of the sidelink CSI report on the uplink channel being determined in association with the priority of the one or more of the at least one uplink transmission or the at least one other SL transmission.

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 user equipment (UE) may inform a base station of multiple transmission-antenna switching capabilities supported by the UE. The supported transmission-antenna switching capabilities may include a first transmission-antenna switching capability and a second transmission-antenna switching capability. The UE may receive a message that triggers the UE to switch from using a first configuration associated with the first transmission-antenna switching capability to using a second configuration associated with the second transmission-antenna switching capability. The UE may perform a sounding procedure using the second configuration associated with the second transmission-antenna switching capability based on receiving the message.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a user equipment (UE) receiving, from a base station, one or more random access channel (RACH) configurations. The RACH configurations may allocate resources for a contention-based RACH procedure for accessing a wireless network. Based on the RACH configurations, the UE may determine a set of random access occasions for an association period. From the set of random access occasions, the UE may map one or more indices of a plurality of synchronization signal blocks to one or more random access occasions. Using the one or more random access occasions, the UE may transmit a random access sequence, including one or more repetitions of the random access sequence to the base station to access the wireless network.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a sidelink communication on a sidelink between the UE and another UE. The UE may transmit, on the sidelink, one or more feedback communications associated with the sidelink communication in a reporting period having a configurable periodicity and/or being configured to occupy an entire bandwidth of a resource pool configured for the sidelink. Numerous other aspects are provided.

Abstract: The present disclosure relates to methods and devices for wireless communication of an apparatus, e.g., a UE and/or a base station. 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.

Abstract: A first user equipment (UE) receives, via first sidelink resources from a second UE, a reservation message that includes an indication of second sidelink resources via which the first UE will subsequently receive a data packet. The first UE may at least one of: determine if the first UE is an intended recipient of the data packet, or compare a reference signal received power (RSRP) value of the reservation message to a threshold value. The first UE may transmit a first reservation forwarding message, via one or more third sidelink resources, including at least the indication of the second sidelink resources to at least a third UE in response to at least one of: determining that the first UE is the intended recipient of the data packet, or determining that the RSRP value is less than the threshold value. The first UE subsequently receives the data packet.
