Abstract: A method, apparatus, and computer-readable medium at a transmitting user equipment (UE) in a distributed cellular vehicle-to-everything environment are disclosed to achieve communications between the distributed UEs with high reliability and low latency. A transmitting UE can configure an ultra-reliable low-latency communication (URLLC) transmission unit by configuring a URLLC channel indicator, a URLLC transmission indicator, a URLLC control channel, and URLLC data portion. The UE can transmit the configured URLLC transmission unit in punctured OFDM symbols within a regular subframe to a receiving UE in the distributed C-V2X environment.

Abstract: Methods, systems, and devices for wireless communication are described that provide for transmitting different sets of control messages through a relay to a central unit (CU) and a core network of a wireless communications system. The different sets of control messages may include a first set of control messages for an access radio link between the relay and the CU and a second set of control messages for a fronthaul radio link between the relay and the CU. Techniques may include multiplexing of messages on a radio bearer (RB), establishment of separate RBs for different control messages, and encapsulation of one type of control message for transmission with the other type of control message.

Abstract: User equipments (UEs) may transmit periodic discovery broadcasts to enable another UE to establish a relay connection to a network. When the UEs transmit respective discovery broadcasts, the discovery broadcasts may cause excessive utilization of network or battery resources. In some aspects, described herein, a first UE, based at least in part on failing to receive a periodic discovery broadcast, may transmit a search signal. A second UE may refrain from transmitting periodic discovery broadcasts based at least in part on a first energy metric not satisfying a first energy metric threshold, but may transmit a discovery broadcast as a response to the search signal based at least in part on a second energy metric satisfying a second energy metric threshold, thereby enabling the first UE to establish a connection to a base station using the second UE as a relay.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may detect one or more base stations based at least in part on synchronization communications associated with the one or more base stations, and may determine one or more priority levels associated with the one or more base stations, wherein a given priority level, of the one or more priority levels, identifies a priority associated with initiating access to a wireless backhaul network via a respective base station of the one or more base stations. The base station may initiate, based at least in part on the one or more priority levels, an access procedure with a set of base stations of the one or more base stations. Numerous other aspects are provided.
