Abstract: Methods, systems, and devices for providing feedback about radio link failure (RLF) events that includes information about directional beams. A user equipment (UE) may experience an RLF event and lose connectivity with a network. After the UE reestablish a radio resource control (RRC) connection with the network, the UE may transmit an RLF report that include information about directional beams, information about a master node and a secondary node in a dual-connectivity procedure, information associated conditional handover procedures, or information about service time interruptions, or a combination thereof. One or more base stations may be configured to transmit at least portions of the information in the RLF report to other base stations as part of a message that may be an example of an RLF indication or a handover report. The message may be transmitted over an X2 interface or an Xn interface.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine one or more candidate base stations for a handover procedure for the UE. The UE may transmit an indication of the one or more candidate base stations to a serving base station. Numerous other aspects are provided.

Abstract: Certain aspects provide a method for wireless communication by a user equipment (UE). The method generally includes determining one or more sidelink discontinuous reception (DRX) configurations associated with at least a communication on a sidelink, determining a wake up indication configuration associated with the one or more sidelink DRX configurations, monitoring for at least one wake up indication from at least one other UE based on the wake up indication configuration, the at least one wake up indication indicating a sidelink DRX on phase associated with the sidelink DRX configuration, deciding an action for the sidelink DRX on phase based on the at least one wake up indication for the at least one communication on the sidelink, and performing the action in accordance with the decision.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to operate in a control mode. In some cases, the control mode may be an in active mode (e.g., a radio resource control (RRC) inactive mode). The UE may be configured to receive a control message from a network node. In some cases, the control message may include an uplink grant associated with a duration. The duration may relate to a timer, such as an expiration timer, for example. The UE may transmit an uplink transmission to the network node while operating in the control mode. The uplink transmission may be in accordance with the uplink grant and the duration. In some cases, prior to transmitting the uplink transmission, the UE may multiplex the uplink transmission with a second control message including an indication for the UE to remain in the control mode.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may detect a radio link failure between the UE and a master node of a dual-connectivity configuration. The UE may transmit, to a secondary node in the dual-connectivity configuration, an indication that the radio link failure has occurred. The secondary node may receive the indication of a radio link failure and transmit the indication of the radio link failure to the master node of the dual-connectivity configuration. The master node may identify a target node for the UE and perform a handover procedure of the UE from the master node to the target node.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for optimizing procedures to update a UE radio capability ID (URCID) when a UE moves to a new Public Land Mobile Network (PLMN) within a registration area. The techniques may help avoid unnecessary signaling traffic and reduce UE power consumption. An example method performed by a user equipment (UE) generally includes receiving at least one URCID assigned by a first PLMN; and taking one or more actions to delay or avoid updating the URCID when moving to a second PLMN in a same registration area as the first PLMN.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a remote user equipment (UE) may transmit, to a relay UE, a request for a Layer 2 relay service and a relay service code associated with the Layer 2 relay service; receive, from the relay UE, a message indicating that the relay UE accepts the Layer 2 relay service associated with the relay service code; establish a radio access signaling radio bearer (SRB) for the Layer 2 relay service using a remote UE radio access SRB configuration; and communicate via the radio access SRB. Numerous other aspects are provided.

Abstract: The present disclosure provides systems, methods, and apparatuses for maintaining continuity of a buffer status report (BSR) from a user equipment (UE) when the UE is handed over between base stations. In one aspect, a base station or a component thereof may be configured to allocate a set of resources for transmission by a UE. The set of resources may have a capacity that is insufficient for an amount of data indicated by a BSR from the UE. The base station or component thereof may be further configured to transmit, to another base station in association with handover of the UE, an indication that the capacity of the set of resources is insufficient for the amount of the data indicated by the BSR.

Abstract: In a wireless access network, a false base station (FBS) may imitate a legitimate base station by repeating the transmissions of the legitimate base station at a higher power level such that one or more user equipment (UEs) synchronize with the FBS instead of the legitimate base station. The present disclosure provides a UE that detects an FBS. The UE may estimate a time of arrival of different multipath components of a downlink signal corresponding to a physical cell identity. The UE may determine an existence of FBS based on a difference between the times of arrival of two of the different multipath components exceeding a threshold amount of time. The UE may perform a mitigation operation in response to determining the existence of the FBS.
