Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may group and selectively multiplex a plurality of random access channel responses (RARs) and radio resource control (RRC) messages in a message B (msgB) communication, together with supplementary scheduling information for other RARs to be mapped to a different msgB communication. The BS may transmit the msgB communication to one or more user equipments. Numerous other aspects are provided.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) derives a time reversal (TR) precoder based at least in part on an estimated channel between the first UE and a second UE, and sends, to the second UE, a TR-precoded sidelink (SL) positioning reference signal (PRS). The estimated channel may be based on channel state information (CSI) associated with a wideband (WB) reference signal (RS). The TR precoder may be based on transmissions or receptions on a SL communication channel between the first UE and the second UE.

Abstract: The present disclosure relates to methods and devices for wireless communication of an apparatus, e.g., a UE and/or a base station. In one aspect, the apparatus may receive, from a base station, at least one SSB. The apparatus may also determine a RSRP of the at least one SSB. Additionally, the apparatus may transmit, to the base station if the RSRP of all of the at least one SSB is less than a threshold, an indication of a reduced UE capability of the UE during a RACH procedure. The apparatus may also transmit, to the base station if the RSRP of one of the at least one SSB is greater than or equal to the threshold, the indication of the reduced UE capability of the UE after entering into a RRC connected state upon completion of the RACH procedure.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a payload for inclusion in an uplink transmission. The UE may organize the payload into a code block group (CBG) that includes one or more code blocks (CB). The UE may map each CB of the CBG to a corresponding uplink shared channel resource unit (e.g., a physical uplink shared channel resource unit) of an uplink transmission occasion of the first UE. The uplink transmission occasion may also be shared with one or more additional UEs such that the CBG of the first UE is multiplexed with additional CBGs from the additional UEs. The UE may transmit, to a base station, the uplink transmission including each uplink shared channel resource unit on which the CBG is organized.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit an uplink (UL) channel of a first radio access technology (RAT) in a first set of radio resources mapped to an UL carrier or a downlink (DL) carrier for a second RAT, where the UL carrier or the DL carrier for the second RAT is used for UL transmission or DL reception of the second RAT in frequency division duplex operation. The UE may receive a DL channel of the first RAT in a second set of radio resources mapped to the UL carrier or the DL carrier for the second RAT. Numerous other aspects are described.

Abstract: The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a user equipment (UE) and/or base station. In one aspect, the apparatus can determine to enter into a two-step RACH procedure in an RRC inactive state. The apparatus can also determine to transmit uplink data in a payload of a message A (MsgA) of the two-step RACH procedure. The apparatus can also transmit the MsgA of the two-step RACH procedure, the MsgA including the payload, the payload including at least the uplink data. Additionally, the apparatus can monitor for a MsgB of the two-step RACH procedure. The apparatus can also receive the MsgB of the two-step RACH procedure, where the MsgB includes a fallback indication including a fallback RAR. Further, the apparatus can retransmit the payload of the MsgA when the MsgB including the fallback indication is received.

Abstract: The aspects described herein are directed to measurement and reporting procedures of an apparatus (e.g., a low-tier user-equipment (UE) or a regular UE) when a bandwidth part (BWP) of the apparatus includes one or both of a first type of synchronization signal block (SSB) (e.g., a cell-defining (CD-SSB)) and second type of SSB (e.g., a non-cell-defining SSB (NCD-SSB)). The apparatus measures at least one of the first type of SSB that is periodically transmitted to a first group of UEs, a second type of SSB that is periodically transmitted within a time window to a second group of UEs, or both the first type of SSB and the second type of SSB for an operation based on a configuration of the operation, and performs the operation based on a measurement of at least one of the first type of SSB, the second type of SSB, or a combination thereof.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a base station may communicate using demodulation reference signal enhancements for control channel repetitions. The UE and the base station may identify a configuration to use to receive or transmit a set of repetitions of control information on a downlink control channel, each repetition of the set of repetitions including one or more symbol periods for an instance of the repeated control information. The base station may transmit, and the UE may receive, a first set of demodulation reference signals in accordance with a first set of parameter values, a second set of demodulation reference signals in accordance with a second set of parameter values, and instances of the control information during the set of repetitions. The UE may decode the control information based on the received signals and configuration.
