Abstract: A target user equipment (UE), which may be a vehicle or UE carried by a pedestrian, may receive sequentially broadcast ranging signals from a set of ranging source entities (SEs), which may be road side units or other vehicles. The target UE further receives location information separately broadcast by each SEs. The location information, for example, may include the position for the SE, the time of transmission of the ranging signals transmitted by the SE and/or a sequence identifier for the SE. The target UE may determine ranges to the SEs using time of arrival measurements for the ranging signals and the time of transmissions of the ranging signals or the sequence identifier received in the location information. The position of the target UE may be determined using the determined ranges to the SEs and the positions of the SEs received in the location information.

Abstract: Certain aspects of the present disclosure provide techniques for improving sidelink positioning via messaging between wireless nodes, e.g., roadside service units (RSUs). A method that may be performed by a user equipment (UE) includes receiving a first positioning reference signal (PRS) from a first wireless node, receiving a second PRS from a second wireless node, receiving, from the first wireless node, an estimate of a first clock error component between the first wireless node and the second wireless node, and estimating a position of the UE, based on the first PRS, the second PRS, and the estimate of the first clock error component.

Abstract: Aspects of this disclosure relate to a user equipment (UE) for wireless communication within a network. The UE receives, from a radio access network (RAN) entity, one of an uplink indication or an uplink port identification associated with an uplink port. The uplink indication and the uplink port identification are associated with an uplink message. The UE also maps one of the uplink indication to a sidelink indication associated with a sidelink message or the uplink port identification to a sidelink port identification associated with a sidelink port and the sidelink message. The UE further superposition codes the uplink message and the sidelink message into a broadcast transmission based on one of (A) the uplink indication and the sidelink indication, or (B) the uplink port and the sidelink port. In addition, the UE transmits, to the RAN entity, the broadcast transmission.

Abstract: Apparatus, methods, and computer-readable media for facilitating beam-based sequence spaces for synchronization signals are disclosed herein. An example method for wireless communication for a first device includes selecting a subset of synchronization signal block (SSB) occasions including SSB occasions within an SSB period, and wherein the subset of SSB occasions is associated with a pairing of a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). The example method also includes transmitting an SSB using at least one SSB occasion from the subset of SSB occasions. An example method for wireless communication for a user equipment (UE) includes selecting a synchronization signal pairing associated with a pairing of a PSS and a SSS, wherein the synchronization signal pairing maps to a subset of SSB occasions including SSB occasions within an SSB period, and also includes monitoring for an SSB at each SSB occasion from the subset of SSB occasions.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE), e.g., such as a pedestrian UE (PUE), may detect, during a first transmission period of a discontinuous transmission cycle, a transmission over a sidelink channel from a second UE that is located within a threshold distance from the first UE, the first UE associated with a first identifier. The first UE may determine, based at least in part on the transmission, a second identifier associated with the second UE, the second identifier being different from the first identifier. The first UE may use, based at least in part on the second UE being within the threshold distance, the first identifier and the second identifier during one or more subsequent transmission periods of the discontinuous transmission cycle.

Abstract: Methods, systems, and devices for wireless communications are described in which a receiving device, such as a receiving user equipment (UE) or vehicle, may provide channel state information (CSI) in which two or more parameters associated with the CSI are provided in a single joint indication. A transmitting device may transmit one or more reference signals and the receiving device may perform one or more measurements on the received reference signal(s). Based on the one or more measurements, the receiving device may determine one or more CSI parameters, such as a rank indicator, channel quality indicator, precoding matrix indicator, or combinations thereof, that may be provided to the transmitting device in a joint indication.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications between a first UE and a second UE. The method includes, at the first UE, receiving, from the second UE, a paging indication message on a sidelink channel, the paging indication message associating the first UE with one or more resources of a common resource pool that includes a plurality of resources for communication on the sidelink channel. The method further includes, based on the received paging indication message, monitoring the one or more resources for a message from the second UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a discontinuous reception (DRX) configuration to be used by the UE for cellular communication with the base station, wherein the DRX configuration indicates a DRX cycle that includes an active time during which the UE is to monitor a physical downlink control channel (PDCCH) and an inactive time during which the UE is to refrain from monitoring the PDCCH; identify a time window for sidelink communication with another UE based at least in part on the DRX configuration; and communicate using one or more sidelink resources in the identified time window. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques relate to the categorization of resources in a system to enable a user equipment (UE) to determine whether resources may be reclaimed. At least two categories may be defined for the resources, and the UE may use various criteria for categorizing the resources in a system. For example, the UE may include a first set of resources in an “available” category and a second set of resources in an “occupied” category. Resources in the “occupied” category may be indicated as occupied by another UE's sidelink channel information. In cases where resources are indicated as reserved for retransmission by another UE, but no feedback is detected, then the UE may use additional parameters to determine whether those resources may be reclaimed for its own transmission and may categorize the resources accordingly.
