Abstract: Methods, systems, and devices for wireless communications are described. A user equipment may determine parameters for congestion metrics based on a type for a channel access procedure associated with a sidelink transmission. The user equipment may determine a channel access procedure type for a sidelink channel transmission, and determine a limit for a channel occupancy (e.g., a channel occupancy ratio) based on the type. The user equipment may compare the channel occupancy with the limit to determine whether to transmit the sidelink channel transmission, based on whether the channel is available. In some aspects, the user equipment may additionally perform the channel access procedure (e.g., a listen before talk procedure) to determine whether to transmit the sidelink channel transmission. The user equipment may also perform channel measurements to obtain a congestion metric (e.g., a channel busy ratio) based on a threshold before transmitting the sidelink channel transmission.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a transmitter user equipment (UE) determines a first zone identifier (ID) corresponding to a first zone in which the transmitter UE is located, determines a distance threshold based on a distance requirement of an application associated with the transmitter UE, determines a second zone ID based on the first zone ID, the distance threshold, a size of the first zone, or any combination thereof, and transmits the second zone ID and the distance threshold to one or more receiver UEs. In an aspect, the receiver UE receives the second zone ID and the distance threshold, determines a distance between the receiver UE and the transmitter UE based on the second zone ID and a location of the receiver UE, and transmits, based on the distance being less than the distance threshold, a feedback message to the transmitter UE.

Abstract: Methods, systems, and devices for sidelink wireless communications are described in which a user equipment (UE), such as a vehicle UE, that supports full-duplex communications may transmit a sidelink control channel during a set of time resources including scheduling information for a subsequent transmission by the UE via a first set of resources. The UE may receive a sidelink control channel during the set of time resources from a second UE that may support full-duplex communications or half-duplex communications. The sidelink control channel may include scheduling information for a subsequent transmission via a second set of time-frequency resources that at least partially overlaps with the first set of time-frequency resources. The first UE may determine that a collision will occur and may perform a resource selection procedure or may transmit a request for the second device to perform the resource selection procedure.

Abstract: Various aspects of the present disclosure generally relate to paging in vehicle to everything (V2X) communications for power saving. In some aspects, a user equipment (UE) may monitor for a wake up signal or a paging message from a wireless communication device and monitor for V2X messages from vehicle UEs based at least in part on receiving the wake up signal or the paging message. The UE may receive a V2X message from a vehicle UE based at least in part on the monitoring. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a signal indicating a wakeup opportunity associated with receiving one or more messages from an application and may identify a mapping between an attribute of the signal and an identifier associated with the application. The UE may determine a wakeup procedure in response to receiving the signal based on the mapping between the attribute of the signal and the identifier associated with the application.

Abstract: Aspects of the disclosure relate to mechanisms for code block segmentation in a wireless communication network (e.g., a sidelink network). In some examples, a wireless communication device may reserve resources across two or more slots on a carrier for transmission of a transport block. The wireless communication device may then select code block parameters for segmenting the transport block into a plurality of encoded code blocks such that each encoded code bock is fully contained within a single slot. In some examples, the code block parameters may include a number of encoded code blocks and a respective size of each of the encoded code blocks.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive, using a set of receive antennas, a first positioning reference signal (PRS). The first UE may transmit, using a set of transmit antennas in response to the received first PRS, a second PRS. The first UE may receive, from a second UE, a control message indicating time and position information for the first PRS transmitted by the second UE and for the second PRS received at the second UE. The first UE may determine a position of the first UE based on the received control message and composite time and position information for the first PRS received at the first UE and for the second PRS transmitted by the first UE.

Abstract: Apparatus and methods for S-SSB transmission are provided. In an aspect, an S-SSS symbol is followed by a gap symbol. In another aspect, a first PSBCH symbol is followed by an S-SSS symbol. In a further aspect, the same MPR is used for the entire S-SSB, thus reducing/mitigating transient periods. For example, the S-SSS symbols in the S-SSB may be selected from a set of sequences having the same MPR as the S-PSS symbols. Alternatively, the MPR of the entire S-SSB may be selected based on a sequence ID of an S-SSS. In an aspect, additional symbols may be configured in the S-SSB to compensate for power reduction.

Abstract: Certain aspects of the present disclosure provide techniques for distance-based HARQ feedback transmission. A method that may be performed by a user equipment (UE) includes monitoring for a data transmission from another UE, receiving an indication of a first zone identifier (ID), determining a nearest zone to the UE of multiple zones, wherein the multiple zones are determined based at least in part on the indication of the first zone ID, determining a distance between the UE and the other UE based on the first zone ID, wherein the determined distance comprises a distance between the UE and the nearest zone, and transmitting hybrid automatic repeat request (HARQ) feedback for the data transmission based at least on the distance.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may be co-located with a sidelink wireless device, such as a road-side unit (RSU). The base station may determine that a cellular user equipment (C-UE) and a vehicle UE (V-UE) are co-located, and altering downlink communications to the C-UE. The RSU may communicate over sidelink with a V-UE, and determine positioning information of a V-UE. The base station may communicate with a C-UE using downlink and uplink communications (e.g., Uu communications), and may determine some positioning information of a C-UE. The base station and RSU may communicate the positioning information of each device, and the base station may determine that the C-UE and V-UE are co-located. The base station may alter a feedback configuration for the C-UE based on the co-location determination.
