Abstract: Certain aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for using information related to a sidelink to optimize operation on a cellular link. According to certain aspects, using a vehicle to everything (V2X) ID of a UE (or a device associated with the UE, such as a vehicle), a base station (e.g., a gNB) may obtain information about the UE from a roadside unit (RSU). The base station may use this information (e.g., UE location, speed, or path information) to help optimize cellular communications with the UE.

Abstract: Aspects presented herein may enable a transmitting device to encode and transmit coordination information and data in separate transport blocks, such that the transmitting device may update the coordination information without altering the transport block carrying the data. In one aspect, an apparatus encodes coordination information for sidelink resources in a first transport block. The apparatus encodes data in a second transport block. The apparatus transmits a first transmission on a PSSCH, the first transmission including the first transport block comprising coordination information and the second transport block.

Abstract: Methods, systems, and devices for wireless communications are described. A network node may store, in a first buffer, a first set of transport blocks (TBs) received at the network node over a wireless channel during a first time window. The network node may store, in a second buffer, a second set of TBs received at the network node over the wireless channel during a second time window and according to at least one monitoring criterion. The network node may receive a first set of one or more network coding messages over the wireless channel. The network node may decode the first set of one or more network coding messages based on the first set of TBs in the first buffer. The network node may transmit a second set of one or more network coding messages corresponding to a portion of the second set of TBs in the second buffer.

Abstract: Aspects presented herein may enable a wireless device to perform an SL ranging based on a single-sided PRS transmission. In one aspect, a first wireless device transmits one or more reference signals to at least one RIS associated with a second wireless device. The first wireless device receives one or more reflected reference signals reflected from the at least one RIS. The first wireless device calculates a signal RTT based on the one or more reference signals and the one or more reflected reference signals. In another aspect, a second wireless device transmits, to a first wireless device, information indicating a time, a duration, or a periodicity in which at least one RIS associated with the second wireless device is to be activated. The second wireless device activate the at least one RIS based on the information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify one or more spectral efficiency ranges that are to be used to select a modulation and coding scheme (MCS) for a sidelink communication. The UE may transmit the sidelink communication using the MCS selected based at least in part on the one or more spectral efficiency ranges. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for channel estimation for two-stage sidelink control using sidelink data channel demodulation reference signals (DMRS). A user equipment (UE) can transmit DMRS for the sidelink data channel. The UE may transmit the second stage of the sidelink control using antenna ports or a precoder used for the sidelink data channel. The receiving device may receive the DMRS, estimate the channel, and demodulate the second stage of the sidelink control based on the estimated channel. The receiving device may flexibly determine the DMRS to use for the estimation and demodulation.
