Abstract: Mechanisms for rate matching a downlink communication channel in a multi-radio access technology (RAT) communication scenario are described. In one aspect, a method for wireless communication performed by a base station (BS) includes rate matching, based on a rate matching pattern indicating a plurality of reserved resource elements, a downlink (DL) communication channel. The method further includes transmitting, to a user equipment (UE) on one or more antenna ports, a DL communication in the rate matched DL communication channel. The method further includes transmitting, on the one or more antenna ports, one or more signals in the plurality of reserved resource elements. The one or more signals transmitted in the plurality of reserved resource elements may allow UEs associated with other RATs to estimate the rate matched DL communication channel.

Abstract: Aspects described herein relate to sidelink transmissions. In an example, a first user equipment (UE) may receive a multi-opportunity grant from a network entity, the multi- opportunity grant indicating multiple listen-before-talk (LBT) opportunities for scheduling a transmission between the first UE and a second UE; perform a LBT procedure for one or more slots of a plurality of slots indicated by the multiple LBT opportunities; select a first slot of the plurality of slots corresponding to an earliest available LBT based on performing the LBT procedure; and communicate a transmission to the second UE during the transmission time interval (TTI) of the first slot.

Abstract: Certain aspects of the present disclosure provide techniques for a method for wireless communication by a user-equipment (UE). The method generally includes receiving, on a control channel, a configuration for an uplink control information (UCI) repetition, determining, in dependence on the control channel, whether to prioritize transmission of the UCI repetition over other uplink signaling, wherein a scheduled resource for transmission of the UCI repetition overlaps with resources for the other uplink signaling, and taking one or more actions associated with communication of the UCI repetition in accordance with the determination.

Abstract: In an aspect, a position estimation entity (e.g., LMF) determines at least one shared requirement (e.g., a timing requirement, an RF chain requirement, etc.) for both of a first differential timing (DT) procedure of a double differential timing (DDT) procedure (e.g., TDOA-based or RTT-based) and a second DT procedure of the DDT procedure, the first DT procedure based on timing measurements between a target user equipment (UE) and first and second wireless nodes, and the second DT procedure based on timing measurements between a reference wireless node and the first and second wireless nodes, and transmits, to at least the target UE and the reference wireless node, requests to perform the DDT procedure along with an indication of the at least one shared requirement for the DDT procedure.

Abstract: Apparatus, methods, and computer-readable media for facilitating indicating cancelation of transmissions of sidelink messages are disclosed herein. An example method for wireless communication at a sidelink device includes transmitting SCI reserving a set of resources for one or more retransmissions of a message, the set of resources identifying one or more reserved resources in a time domain. The example method also includes identifying a skipped transmission associated with one or more of the set of resources reserved by the sidelink device. Additionally, the example method includes transmitting a cancelation indication indicating the skipped transmission, the cancelation indication indicating that the skipped transmission corresponds to a previous reserved resource in the time domain, a current reserved resource in the time domain, or a future reserved resource in the time domain.

Abstract: The present disclosure provides systems, methods, and apparatuses for grouping beams that are directionally associated with one another and associating respective properties associated with groups of beams. In one aspect, a UE or component thereof may be configured to select a first beam group of one or more beam groups to include a first beam of a set of beams, with the first beam group including a first subset of beams of the set of beams that is directionally associated with a first direction of the first beam. The UE or component thereof may be further configured to associate a respective set of properties with each of the one or more beam groups. The UE or component thereof be configured to communicate via the first beam of the first beam group of the one or more beam groups.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure, for a first beam group of a set of beam groups associated with the UE, a first channel busy ratio (CBR) for the first beam group. The UE may receive, from a second UE, an indication of a second CBR for a second beam group associated with the second UE. The UE may transmit, to the second UE using a beam included in the first beam group, a signal using one or more transmit parameters that are based at least in part on at least one of the first CBR or the second CBR. Numerous other aspects are described.

Abstract: Disclosed are systems and techniques for performing sidelink communications. For instance, a first client device can determine a first transmit power parameter for transmitting sidelink communications. The first transmit power parameter can either be received from a base station associated with the first client device or it can be a default parameter based on the first client device not being associated with a base station. The first client device can transmit, to a second client device, a first sidelink transmission having a first power level corresponding to the first transmit power parameter. The first client device can receive, from the second client device, a first sidelink reception having a second power level corresponding to a second transmit power parameter.

Abstract: Certain aspects of the present disclosure provide techniques for demodulation reference signal (DMRS) sequence selection. One aspect provides a method for wireless communication by a first wireless node. The method generally includes selecting a type of DMRS sequence to be used for communication with a second wireless node based on a signal quality associated with the communication, receiving a message having the type of DMRS sequence, and performing channel estimation based on the DMRS sequence using the message.

Abstract: Aspects of the present disclosure relate to techniques for physical uplink control channel configuration and coverage enhancement in a wireless communication network. A base station can dynamically indicate a repetition factor for an uplink control channel to improve coverage of the uplink control channel. The base station can explicitly or implicitly indicate the repetition factor using various signaling techniques. The interpretation of an indication of a repetition factor can depend on one or more parameters, for example, a physical uplink control channel (PUCCH) format, an uplink control information size, a code rate, and/or a PUCCH resource set used for the PUCCH.
