Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may identify a first set of resources for an access link communication between the first UE and a base station. The UE may identify a second set of resources for a sidelink communication between the first UE and a second UE. The UE may identify a scheduling conflict between the first set of resources for the access link communication and the second set of resources for the sidelink communication. The UE may drop at least a portion of the first set of resources for the access link communication or the second set of resources for the sidelink communication based at least in part on the identification of the scheduling conflict and a prioritization rule. Numerous other aspects are provided.

Abstract: Example implementations include a method, apparatus and computer-readable medium of wireless communication over a sidelink between a first user equipment (UE) and a second UE. The first UE may receive, from a base station, a first sidelink grant for a transmission between the first UE and the second UE. The first UE may communicate the transmission according to the sidelink grant. The first UE may monitor a configured duration of a sidelink round trip time timer from the transmission. The first UE may monitor a configured duration of a sidelink retransmission timer from an end of the sidelink round trip time timer. The first UE may allow start of a discontinuous reception (DRX) mode after the duration of the sidelink retransmission time if a second grant is not received during the sidelink retransmission timer.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may identify a resource for wireless communication, the resource being in a first state where the resource is active for wireless communication and is inactive for a communication failure recovery procedure. The wireless device may determine that a communication failure has occurred during a first communication period. In some cases, one or more techniques for confirming the communication failure may be used to verify the failure. The wireless device may transition during a second communication period and based at least in part on the communication failure, the resource to a second state where the resource is inactive for wireless communication and is active for the communication failure recovery procedure. The wireless device may perform the communication failure recovery procedure using the resource transitioned to the second state.

Abstract: Methods, systems, and devices for wireless communication are described to support security techniques for ranging in wireless networks. A first device may transmit an indication to initiate a ranging procedure with a second device, and in response to the indication, the second device may transmit signaling to the first device and to one or more third devices. The first device and the one or more third devices may each determine a respective location metric associated with the second device based on the signaling. The one or more third devices may each transmit, to the first device, the respective location metric. Based on the communicated location metric(s), the first device may determine whether an eavesdropper is present and may communicate with the second device based on the determination.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify time and frequency resources for a physical downlink shared channel (PDSCH) to be transmitted to a user equipment (UE) in a first transmission time interval (TTI). The base station may transmit configuration information for a control channel search space set in a second TTI. The second TTI may precede the first TTI. The configuration information may include an indication of an absence of a physical downlink control channel (PDCCH) transmission to send in the control channel search space set indicating the identified time and frequency resources for the PDSCH, and a set of time and frequency resources for the control channel search space set. The UE may receive the configuration information and identify the time and frequency resources allocated for the PDSCH in the second TTI, and receive the PDSCH transmission in the second TTI.

Abstract: Techniques and apparatus for avoiding hybrid automatic repeat request (HARQ) process identifier (ID) conflicts in scenarios where multiple semi persistently scheduled (SPS) configurations share the same pool of HARQ process IDs are provided. One technique involves receiving an indication of SPS configurations, where each SPS configuration allocates a set of SPS occasions for physical downlink shared channel (PDSCH) transmissions. A conflict is detected between a first HARQ process ID associated with a first SPS occasion of a first SPS configuration and a second HARQ process ID associated with a second SPS occasion of a second SPS configuration, where the first SPS occasion occurs prior to the second SPS occasion. At least one action to resolve the conflict is taken based on predetermined rule(s), in response to detecting the conflict.

Abstract: Aspects relate to signaling at least one relaying parameter for a wireless communication device that supports relaying operations. In some examples, the wireless communication device may send such a relaying parameter to a scheduling entity. The scheduling entity may then schedule a relaying operation for the wireless communication device based on the relaying parameter. For example, the scheduling entity may select the resources to be used for the relaying operation based on the relaying parameter. In some examples, a relaying parameter may indicate one or more of a relaying capability of a wireless communication device, an operational condition (e.g., requirement) for relaying by a wireless communication device, a relaying configuration for a wireless communication device, or a combination thereof.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to mobility techniques that allow for dynamically updating a set of cells activated to serve a user equipment (UE) and the cell in the set of cells designated as the primary cell (PCell). An example method includes receiving signaling indicating a set of cells supported by one or more distributed units (DUs) under a common central unit (CU); identifying a subset of the set of cells activated to serve the UE, wherein a first cell of the activated cells comprises a primary cell selected from cells included in a candidate set of primary cells (PCells); and identifying another one of the activated cells to serve as the PCell if the first cell is re-designated as a secondary cell (SCell), wherein the other one of the activated cells comprises a cell selected from the candidate set of PCells.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for radio link monitoring reference signal (RLM-RS) determination using communications systems operating according to new radio (NR) technologies. For example, a method for wireless communications from a UE generally includes determining resources to monitor for radio link monitoring (RLM) prior to being configured with resources to monitor for RLM after establishing a radio resource control (RRC) connection with a network, and performing RLM based on the determined resources.
