Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain one or more measurements associated with a sidelink resource pool that includes one or more time and frequency resources allocated to sidelink transmissions to or from the UE. The UE may transmit, to an assisted UE, sidelink signaling that includes signaling to wake up the assisted UE and resource assistance information indicating the one or more measurements associated with the sidelink resource pool. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may determine a default operating mode based on the geographic location (e.g., zone) of the base station, for user equipment (UEs) operating in that zone to use. The operating mode may be a full duplex (FD) operating mode or a half duplex (HD) operating mode. A UE operating in the zone may receive, from the base station, an indication of the default operating mode corresponding to the zone, and may select an operating mode based on the indication. The mode selected by the UE may be the same as or different than the indicated default operating mode. For example, the UE may determine to use either FD mode or HD mode based on operation parameters, interference measurements, signaling from a base station or other UEs, one or more measurement thresholds, or some combination thereof.

Abstract: Techniques described herein provide for identification of a mobile device that belongs to an observed pedestrian, by a vehicle. According to embodiments, a vehicle can receive a mobile device message including a first set of pedestrian-identifying features, and the vehicle can use vehicle sensor data to extract a second set of pedestrian-identifying features for an observed pedestrian. If the features match, the vehicle can determine that the observed pedestrian is in possession of the mobile device, and the vehicle can subsequently communicate with the mobile device as needed regarding the status of the pedestrian.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device supports sidelink communications, including device-to-device (D2D) communications and vehicle-based communications. The communication device receives, from another device, a discontinuous transmission (DTX) configuration for a sidelink connection between the communications device and the other device. Based on the received DTX configuration, the communications device determines a discontinuous reception (DRX) configuration and transmit, to the other device, the determined DRX configuration. The devices experience power savings, among other results according to the DTX configuration or the DRX configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE), may receive, at a processing layer of the UE, sets of discontinuous reception (DRX) cycle parameters from a corresponding set of applications at an application layer of the UE. The UE may determine, based on the sets of DRX parameters, a common DRX cycle to satisfy each of the sets of applications. The UE may transmit the common DRX cycle to one or more layers in the user plane protocol stack of the UE. A base station may also receive a request, from the UE, for a set of DRX cycle parameters that satisfies the common DRX cycle of the UE. The base station may transmit an indication of the set of DRX parameters, and receive, from the UE, a confirmation of a DRX cycle associated with the set of DRX cycle parameters.

Abstract: In a particular implementation, a method of wireless communication includes transmitting, from a first user equipment (UE) to a second UE, a radio resource control (RRC) request that includes a first discontinuous reception (DRX) preference at the first UE. The method also includes receiving, at the first UE from the second UE, a RRC setup message that includes a second DRX preference at the second UE. The method further includes transmitting, from the first UE to the second UE, a RRC setup complete message that includes an indication of a confirmed DRX cycle.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit concurrent messages over a sidelink channel to another UE and over an uplink channel to a base station. The UE may transmit, to a base station, a report indicating a capability of the UE to concurrently transmit over a sidelink channel and an uplink channel. The UE may receive, from the base station and based on the report, a transmission configuration scheduling a concurrent sidelink and uplink transmission within a resource shared by the sidelink channel and the uplink channel. The UE may then transmit the concurrent sidelink and uplink transmission within the resource shared by the sidelink channel and the uplink channel based on the transmission configuration. The other UE and the base station may receive the concurrent sidelink and uplink transmission and may decode different layers of the transmission.

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.

Abstract: Methods, systems, and devices for wireless communications are described that provide for cooperative full-duplex techniques for sidelink communications. A first device that supports full-duplex communications may transmit a first message to a second device while concurrently receiving a second message from a third device. The first device may determine a set of parameters that indicate a presence of one or more objects that cause interference at the first device based on communicating with the second and third devices. The set of parameters may include location information, directional beam information, main beam information, and null interference beam information, or velocity information, or any combination thereof. The first device may broadcast an indication of the set of parameters to other devices. In some examples, a device that receives the set of parameters may determine communications parameters for communication with other devices that accounts for the indicated objects.

Abstract: Certain aspects of the present disclosure provide techniques for dynamically controlling sidelink resources in a communication network. In one aspect, a method for configuring resources in a communication network, includes: establishing a first data connection with a user equipment; establishing a second data connection with a vehicle user equipment; transmitting to the user equipment via the first data connection an indication to activate a pool of V2X sidelink resources; and transmitting to the vehicle user equipment via the second data connection the indication to activate the pool of V2X sidelink resources.
