Abstract: Certain aspects of the present disclosure are directed to a method for wireless communication by a network entity. The method generally includes generating a configuration message for a user-equipment (UE) to perform one or more reference signal (RS) measurements on one or more resources of a sidelink channel, transmitting the measurement configuration message, receiving a measurement report indicating results of the one or more RS measurements, and transmitting a scheduling message indicating resources for sidelink transmission on the sidelink channel.

Abstract: Aspects are provided of dedicated paging schemes for vehicle UEs to communicate with pedestrian UEs in V2P communication and that also allows pedestrian UEs to power-efficiently monitor for such V2P communications. A vehicle UE provides an indication of a V2P communication to a pedestrian UE in a resource from a plurality of resources. The vehicle UE then transmits a message to the pedestrian UE based on the indication. The pedestrian UE monitors the plurality of resources for the indication of the V2P communication from the vehicle UE. The pedestrian UE receives the indication of the V2P communication. The pedestrian UE then receives the message from the vehicle UE based on the indication.

Abstract: Certain aspects of the present disclosure provide techniques for conveying information via medium access control (MAC) control element (CEs). In some cases, the MAC-CEs may relate to sidelink communications between two user equipments (UEs). A first wireless node may send the first MAC-CE on at least one of a sidelink or a cellular link and provide providing routing information for the first MAC-CE. The routing information may indicate, for example, a source node, a destination node, or a transit route through one or more nodes. The routing information may also indicate whether traffic sent with the first MAC-CE is relayed traffic or traffic originating at the first node.

Abstract: Aspects described herein relate to measuring a signal quality at at least one receive beam while transmitting, in full duplex communications, over each of one or more transmit beams associated with the at least one receive beam, and determining, based at least in part on the measured signal quality associated with each of the one or more transmit beams and the at least one receive beam, a transmit/receive beam pair to use in full duplex communications with one or more other nodes.

Abstract: Systems, apparatuses, and methods for switching between full duplex and half duplex in wireless nodes. A wireless node may measure self-interference for one or more transmitter-receiver beam pairs. Based on the self-interference measurements, the wireless node may communicate on a beam pair in full duplex or half duplex. A duplex mode may be determined based on self-interference, as well as, optionally with other metrics such as rate and latency. A wireless node may switch between full duplex and half duplex based on the duplex mode determination. In addition, suitable beam pairs may be selected, along with associated duplex modes.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a transmitter user equipment (UE) determines a first demodulation reference signal (DMRS) pattern for a first slot allocated for transmission over a sidelink between the transmitter UE and a receiver UE, wherein the first DMRS pattern is determined based at least on the first slot having a first slot format of two or more slot formats, and transmits, to the receiver UE, DMRS in the first slot according to the first DMRS pattern. In an aspect, the receiver UE determines the first DMRS pattern for the first slot based at least on the first slot having the first slot format, and receives, from the transmitter UE, DMRS in the first slot according to the first DMRS pattern.

Abstract: Disclosed are techniques for transmitting and receiving a plurality of encoded information bits on a radar signal. In an aspect, a transmitter radar generates a first set of modulated phase-coded symbols to convey the plurality of encoded information bits, generates a second set of modulated phase-coded symbols as reference symbols having a known phase modulation, phase codes a plurality of chirps of the radar signal according to the first and second sets of modulated phase-coded symbols, and transmits the plurality of chirps according to the phase coding. A receiver radar determines a phase difference between the receiver and transmitter radars based on a phase of the plurality of chirps, equalizes the phase based on the determined phase difference, determines a phase code of the first set of symbols based on the equalized phase, and decodes the encoded information bits based on the phase code of the first set of symbols.

Abstract: Certain aspects of the present disclosure provide techniques for sidelink communication. A method that may be performed by a user equipment (UE) includes selecting a modulating and coding scheme (MCS) and a transmission power based on a configured dependency between one or more candidate MCSs and one or more candidate transmission powers, and transmitting, via a sidelink channel, one or more frames using the selected MCS and the selected transmission power.
