Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives information from a serving base station and at least one neighboring base station. The information indicates a time allocation of discovery resources allocated by each of the serving base station and the at least one neighboring base station for performing direct discovery. The apparatus further determines a subframe timing of the serving base station and the at least one neighboring base station, and performs direct discovery using the time allocation of the discovery resources allocated by each of the serving base station and the at least one neighboring base station based on a determined subframe timing of the serving base station or a neighboring base station corresponding to the discovery resources.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit an uplink message (e.g., a scheduling request) indicating one or more beam directions (e.g., one beam direction, a set of beam directions, a sequence of beam directions), one or more beamwidths (e.g., for the one or more indicated beam directions), an angular area of interest for radar sensing, or a combination thereof. The network entity may then provide, to the UE, a grant of resources for performing the radar sensing on specific radar sensing transmit beams (e.g., that will not interfere with other radar sensing by other UEs, uplink communications form other UEs, sidelink communications by other UEs, etc.). The UE may indicate the directions of the beams with reference to a global coordinate system. The network may configure the UE with lookup tables (LUTs) defining relationships between indices, beam directions and/or beamwidths.

Abstract: An apparatus (e.g., a third UE) may be configured to detect at least one SPS conflict in a set of REs between a first SL (e.g., an SPS-based) transmission associated with a first UE and a second SL transmission associated with a second UE. The third UE may further be configured to transmit, upon detecting the SPS conflict, an indication of the SPS conflict to at least one of the first and second UEs. A first UE may be configured to receive, from the third UE, the indication of the SPS conflict, the indication of the SPS conflict including information regarding a set of resources associated with the detected conflict. The first UE may be further configured to initiate a resource re-selection for the first SL transmission based on the received indication and to transmit the first SL transmission based on the resource re-selection.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless device may transmit an orthogonal frequency division multiplexing (OFDM) signal on K subsets of N subcarriers, where the signal includes a sequence of modulated symbols for each subset of the K subsets that is distinct for each subset. The wireless device may receive a reflected OFDM signal that corresponds to the OFDM signal. The wireless device may process the reflected OFD.M signal with K mixers, where mixer frequencies for the K mixers are separated by N subcarriers spacing, to form K portions of a range spectrum from the reflected OFDM signal. The wireless device may combine the K portions to form the range spectrum. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit a discovery message to discover another UE with which to establish a cooperative radar sensing session. The first UE may receive, from a second UE, a join request for the first UE to establish the cooperative radar sensing session with the second CE, The first UE may transmit, to the second UE, an acceptance indication based at least in part on the join request. The first UE may communicate with the second UE to establish a joint configuration to be used by the first UE and the second UE for the cooperative radar sensing session, Numerous other aspects are described.

Abstract: Methods systems, and devices for wireless communications are described. A first wireless device may transmit a first radar signal in a first frame, and may receive a reflected signal corresponding to the first radar signal in a second frame. The first wireless device may also receive a number of different transmissions including at least a second transmission from a second wireless device. To determine which signals are reflections from the first radar signal and which signals are interference. the first wireless device may monitor a third frame that is subsequent to the first and second frames for one or more interfering signals during a silence interval. In some other cases, the first wireless device may transmit a request for the second wireless device to modify a timing offset for the second transmission, and may monitor for the second transmission which may be shifted in frequency according to the timing offset.

Abstract: Methods, systems, and devices for wireless communications are described. For example, devices of a wireless communications system may be configured to support various techniques for sidelink communications using an unlicensed spectrum, where such sidelink communications are coordinated at least in part by a network device, such as a base station or entity thereof. In some examples, a base station may determine to offload some sidelink communications to the unlicensed spectrum, which may be based on capability information, system channel loading, application priority, periodicity, or quality of service, among other criteria or combinations thereof. Based on such a determination to offload sidelink communications to the unlicensed spectrum, the base station may transmit an indication for one or more user equipments (UEs) to attempt to perform sidelink communications using the unlicensed spectrum (e.g., based on an evaluation of an availability of the unlicensed spectrum by a UE initiating sidelink transmissions).

Abstract: Certain aspects of the present disclosure provide a method performed by a first apparatus including a radar device. The first apparatus transmits first operating information associated with the first apparatus indicating a geographical location and a direction of the first apparatus to a second apparatus in an environment. The first apparatus receives second operating information from the second apparatus indicating a geographical location and a direction of the second apparatus. The first apparatus identifies a group of interfering apparatuses, including the first apparatus and the second apparatus, based on the first and second operating information. The group of interfering apparatuses is associated with a same time synchronization source. The first apparatus transmits a first plurality of signals via the radar device based on a common radar transmission configuration for the group of interfering apparatuses.

Abstract: Methods, systems, and devices for wireless communications are described. User equipment (UE) may communicate sidelink coordination messages to indicate potential interference and select sidelink resources. For example, a first UE may transmit a sidelink coordination message to a second UE that includes a set of identifiers associated with a set of UEs. The second UE may select a first set of sidelink resources for a first sidelink communication with the first UE based on a reference signal received power (RSRP) of the sidelink coordination message and a reservation of a second set of sidelink resources for a second sidelink communication between the first UE and third UE of the set of UEs. For example, the second UE may determine the reservation, select the first set to be non-overlapping a time domain with the second set based on the RSRP, and perform the second sidelink communication with the first UE.

Abstract: A user equipment (UE) can transmit first radio access information indicating a first ratio of first sidelink devices configured to use a first radio access technology (RAT) to second sidelink devices configured to use a second RAT. The UE can receive second radio access information from one or more sidelink devices of at least one of the first sidelink devices or the second sidelink devices. Each second radio access information indicates a respective second ratio of the first sidelink devices configured to use the first RAT to the second sidelink devices configured to use the second RAT. The UE can select a resource pool frame structure based on the first ratio and each of the respective second ratios, and the resource pool frame structure is configured to partition a resource pool between the first RAT and the second RAT for sidelink communication in a sidelink network.
