Abstract: Methods, systems, and devices for wireless communications are described. An example method for wireless communication at a first user equipment (UE) may include receiving at least a first sidelink transmission from a second UE, wherein at least a second sidelink transmission from a third UE is scheduled contemporaneously with at least the first sidelink transmission from the second UE. The method may also include transmitting an indication in a transmission occasion to at least one of the second UE or the third UE based at least in part on a prioritization of information for the transmission occasion, wherein the indication indicates that at least the first sidelink transmission from the second UE is scheduled contemporaneously with at least the second sidelink transmission from at least the third UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device may receive, on a sidelink and from a second wireless communication device, resource reservation information associated with the second wireless communication device. The resource reservation information may identify sidelink resources that are reserved for the second wireless communication device for transmission on the sidelink. The first wireless communication device may transmit, on the sidelink, the resource reservation information to a third wireless communication device. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE on a sidelink channel, a configuration message that includes an indication of a first set of reference signals associated with a first transmit-receive point (TRP) of the first UE, an indication of a second set of reference signals associated with a second TRP of the first UE, and an indication to refrain from combining measurements based at least in part on the first set of reference signals with measurements based at least in part on the second set of reference signals. The first UE may further transmit, using the first TRP of the first UE, the first set of reference signals, and transmit, using the second TRP of the first UE, the second set of reference signals. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for low power channel sensing for pedestrian user equipments (P-UEs). A method that may be performed by a UE (e.g., such as a P-UE) includes determining a level of channel congestion for a channel during a first sensing duration. The method includes determining a second sensing duration and a transmission duration based on the level of channel congestion for the channel determined from the first sensing duration. The method includes sensing the channel for the second sensing duration. The method includes transmitting on the channel for the transmission duration.

Abstract: In one aspect, a method of wireless communication includes receiving, by a user equipment (UE), a downlink control signaling scheduling one or more uplink transmissions for one or more transmission resources. The method also includes determining, by the UE, to perform superposition transmission operations for at least one transmission resource of the one or more transmission resources. The method further includes transmitting, by the UE, an uplink channel data transmission and a sidelink channel data transmission in a same transmission resource, responsive to determining to perform superposition transmission operations for the least one transmission resource. Other aspects are described and claimed.

Abstract: Methods, systems, and devices for wireless communications are described. The methods include determining a sidelink message to transmit to a second user equipment (UE) over a time resource of a sidelink connection between a first UE and the second UE, encoding at least a subset of time periods of the time resource according to a configuration that is based on a switching time for the second UE for switching from a receiving mode to a transmitting mode during reception of the sidelink message during at least the subset of time periods of the time resource, and transmitting the sidelink message to the second UE using a set of time periods of the time resource that includes the subset of time periods.

Abstract: Various aspects of the present disclosure generally relate to roadside unit relay for sidelink communications. In some aspects, a user equipment (UE) may determine a resource in which to monitor for a message from a wireless communication device, where the message is based at least in part on information from one or more vehicle to everything (V2X) messages received by the wireless communication device. The UE may monitor for the message only in the resource and receive the message in the resource. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. The method may involve a first user equipment (UE) receiving an indication of a set of sidelink resources and an indication of a set of uplink resources for transmitting sidelink feedback information. The first UE may receive a sidelink shared channel transmission from a second UE and upon receiving the sidelink shared transmission, generate feedback information regarding the sidelink shared channel transmission and transmit the feedback information directly to the base station using the set of uplink resources.

Abstract: Methods, systems, and devices for wireless communications are described. A device may determine a packet for transmission and determine whether to transmit a reservation signal prior to the transmission of the packet based in part on a condition. The condition may include, but is not limited to, a packet size, or a packet priority, or a combination thereof. According to the determination, the device may refrain from transmitting the reservation signal or allocate resources for the reservation signal from a same resource pool associated with the transmission of the packet or a dedicated resource pool according to a pre-reservation resource pattern.
