    Abstract: In some wireless systems (e.g.. 5G new radio (NR) systems), a user equipment (UE) may experience coexistence interference when using collocated radio transceivers to simultaneously communicate using different radio access technologies (RATs). To mitigate the coexistence interference, the UE may transmit a configuration request to a base station, where the configuration request may identify that the UE is operating on multiple RATs and identify that the UE is experiencing coexistence interference. Aspects of the present disclosure may further provide techniques for coexistence interference mitigation in wideband systems by allowing the UE to indicate the specific bandwidth parts (BVVPs) that are impacted by IDC interference to the base station such that the network can resolve the IDC interference by reconfiguring the bandwidth, instead of performing inter-frequency handover or removing /deactivating affected SCells.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may detect a trigger to initiate determination of a performance parameter for a packet data convergence protocol (PDCP) duplication procedure associated with a PDCP instance. The wireless communication device may receive packets of the PDCP instance via multiple radio link control (RLC) entities according to the PDCP duplication procedure. The wireless communication device may determine the performance parameter based at least in part on whether packets of the PDCP instance are successfully received via one or more RLC entities of the multiple RLC entities. Numerous other aspects are provided.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate a report for one or more two-step random access channel (RACH) procedures between the UE and a base station (BS), wherein the RACH report includes at least one of an indication of a quantity of message A (MsgA) payloads transmitted during the one or more two-step RACH procedures on each beam of one or more beams associated with the BS, an indication of one or more parameters associated with each MsgA communication transmitted during the one or more two-step RACH procedures, or an indication of whether a respective signal strength for each beam, associated with the one or more two-step RACH procedures, satisfies a signal strength threshold. The UE may transmit the report to the BS. Numerous other aspects are provided.

    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: Certain aspects of the present disclosure provide techniques for an on-demand measurement gap for inter-frequency radio resource management (RRM) measurements. A method for wireless communications by a base station (BS) includes configuring a user equipment (UE) in the serving cell for measurement of target cell (s) and with an on-demand measurement gap configuration for measuring the target cell (s). Neighbor cells in a same frequency can coordinate to align synchronization signal block (SSB) or channel state information reference signal (CSI-RS) transmission and provide timing information of the aligned SSB or CSI-RS transmission to a cell in a different frequency. A method by a UE includes receiving an on-demand measurement gap configuration from a serving cell co and measuring target cell (s) based on the measurement gap configuration.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) measure and report cell measurements for neighboring cells to assist the wireless network with handover decisions. In some cases, the UE may be configured to report beam-level measurements for just a subset of neighboring cells instead of each neighboring cell. For example, the UE may measure, or report beam measurements for a subset of the neighboring cells which meet configured criteria or are included in a subset of cells configured by the serving cell. Techniques for configuring and maintaining the subset of cells are described herein. For example, the cells in the subset may be configured by the UE or the serving cell of UE. A cell may also be removed from the subset if the cell does not continue to meet criteria for being included in the subset.
