Abstract: Aspects relate to managing a device-to-device communication link via radio resource control (RRC) layer signaling. In an example operation, a first wireless communication device establishes a unicast link with a second wireless communication device over a device-to-device communication interface and determines that the unicast link is to be reconfigured with at least one updated parameter. The first wireless communication device then sends a link reconfiguration request to the second wireless communication device via a first RRC message over the communication interface. The first RRC message includes the at least one updated parameter. The first wireless communication device receives a link reconfiguration response from the second wireless communication device via a second RRC message over the communication interface based on the link reconfiguration request and determines whether to reconfigure the unicast link using the at least one updated parameter based on the received link reconfiguration response.

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 sidelink resource configuration indicating physical sidelink control channel (PSCCH)/physical sidelink shared channel (PSSCH) occasions on which to monitor a PSCCH for a grant from a second UE. The first UE may determine an active time for monitoring the PSCCH based on a discontinuous reception (DRX) mode for a link with the base station, the DRX mode including an active state in which a physical downlink control channel (PDCCH) is monitored and an inactive state in which the PDCCH is not monitored. The first UE may monitor the PSCCH during one or more of the PSCCH/PSSCH occasions that coincide with the active time.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may transmit sidelink discontinuous reception (DRX) information to a base station while operating in a connected mode. In some examples, the UE may include the sidelink DRX information in UE-assistance information (UAI). The sidelink DRX information may include a preference of a DRX cycle, a DRX active duration, a DRX inactive duration, and the like, for sidelink DRX operation. The UE may receive a message including a sidelink DRX configuration from the base station based on the sidelink DRX information and operate according to the sidelink DRX configuration.

Abstract: Aspects presented herein may enable wireless communications to be adaptive to a dynamic environment, where wireless devices may manage wireless communications, such as performing beam managements, based at least in part on environmental conditions. In one aspect, a network entity receives, from a sensor device or a UE, a request for an ML data service. The network entity establishes, with the sensor device or the UE, the ML data service based on the request. The network entity receives, from the sensor device, ML data including a set of features extracted from at least one sensor of the sensor device or information indicative of at least one beam for the ML data service. The network entity transmits, to the UE, a beam indication to modify the at least one beam based at least in part on the ML data received from the sensor device during the ML data service.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for assisted connectivity techniques. For example, a UE may transmit, to an AN, a request to establish a RRC connection with a PN, and the AN may further transmit, to the PN, the request received from the UE to establish the RRC connection with the PN. After receiving the request, the PN may transmit, to the AN, one or more RRC connection parameters for the RRC connection with the UE, and the AN may further transmit, to the UE, the one or more connection parameters received from the PN for establishing the RRC connection with the PN. Based on the one or more parameters received from the AN, the UE may establish the RRC connection with the PN.

Abstract: Certain aspects of the present disclosure provide techniques for relay reselection triggering in sidelink relay systems. An example method for relay reselection triggering by a relay user equipment (UE) generally includes detecting a radio link failure (RLF) on at least one of a first link between the relay UE and a serving network entity or a second link between the relay UE and a remote UE and taking one or more actions, in response to the detection, to trigger relay reselection by the remote UE.
