Abstract: A user equipment (UE) and base station may be configured to implementing trigger-based joint TX-RX sensing for channel access. In some aspects, the UE may monitor, via a receiver, for one or more transmissions from a first base station, detect, during the monitoring, interference associated with a pre-grant communication, the pre-grant communication associated with a future communication between a second base station a second user equipment, and transmit, via a transmitter, a reservation communication to the second base station in response to the pre-grant communication. In some aspects, the UE may receive the one or more communications from the first base station, without interference from the second base station, based on transmitting the reservation communication.

Abstract: In one aspect of the disclosure, a UE may be configured to receive, from a base station, information indicating a reference point associated with at least one L1 measurement; determine a reporting value of the at least one L1 measurement based on a difference between the reference point and a measured value of the at least one L1 measurement; and transmit information indicating the reporting value to the base station. In another aspect, a RAN node can indicate to a UE that a reduced measurement report resolution is to be used for beam measurements in a measurement report. The reduced measurement report resolution is less than a first measurement report resolution previously indicated to be used for the beam measurements. Lower resolution can be obtained by using fewer bits to indicate one or more of the beam measurements. The payload for a measurement report such as a L-SINR or L-RSP L1 measurement report is thereby reduced when the UE transmits the measurement report to the RAN node.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, in a single dynamic signaling communication, an indication to activate one or more coverage enhancement parameters. The UE may activate the one or more coverage enhancement parameters based at least in part on receiving the indication. Numerous other aspects are provided.

Abstract: In cross-carrier scheduling of DCIs on a data channel, a base station may transmit a first DCI on a first radio frequency (RF) carrier, where the first DCI schedules a data channel of a second RF carrier (and optionally indicates that the base station will transmit at least one DCI on the data channel of the second RF carrier). In some examples, the base station may transmit the first DCI in a control channel of the first RF carrier. In some examples, the base station may transmit the first DCI in a data channel of the first RF carrier. In some examples, the base station may transmit, in a data channel of the second RF carrier, a second DCI that indicates that the base station will transmit at least one DCI in the data channel of the first RF carrier.

Abstract: A method of wireless communication by a UE (user equipment) includes receiving group-common downlink control information (DCI) indicating coverage-enhancements including channel state information (CSI) report settings for a group of UEs and/or PDCCH repetition. The method also includes reporting CSI in accordance with the coverage-enhanced CSI report settings, which may include report repetition. A method of wireless communication by a base station includes transmitting group-common downlink control information (DCI) indicating coverage-enhanced channel state information (CSI) report settings and/or PDCCH repetition for a group of UEs. The method also includes receiving CSI reports from the group of UEs in accordance with the group-common DCI.

Abstract: Orthogonal frequency-division multiplexing (OFDM) numerologies that maintain symbol boundary alignment while distributing excess cyclic prefixes (CPs) among OFDM symbols. Communication is established using a first sub-carrier spacing (SCS) and a first OFDM numerology, such as an exemplary numerology that distributes excess CP duration among a set of symbols that occupy a time interval within or equal to a corresponding time interval of a symbol of a second OFDM numerology with a second lower SCS. The first SCS may be, e.g., 960 kHz. The second SCS may be, e.g., 120 kHz. Another exemplary OFDM numerology described herein distributes the excess CP as prefix and postfix portions to one of the symbols, such as the first symbol of a set. Communication then proceeds using the first OFDM numerology at the first SCS and, in illustrative examples, using the second OFDM numerology at the second SCS or other OFDM numerologies at other SCSs.

Abstract: Aspects of the disclosure relate to wireless communications systems including the use of a joint grant generated in and transmitted by a base station to a user equipment (UE) over a first communication link for establishing a sidelink (SL) with a relay UE. The joint grant provides a first resource assignment for establishing the SL between the UE and relay UE, as well as a second resource assignment that is transmitted to the relay UE for establishing an uplink from the relay UE to the base station.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit, and a user equipment (UE) may receive, initial timing advance information in a msg2 communication of a four-step random access channel procedure based at least in part on a subcarrier spacing in a cell associated with the base station. The UE may transmit, and the base station may receive, a msg3 communication with an initial timing advance that is based at least in part on the initial timing advance information. The base station may transmit, and the UE may receive, updated timing advance information resolving a timing advance wrap-around between the UE and the base station based at least in part on the base station detecting the msg3 communication. 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.
