Abstract: Handover criteria for wireless networks are provided. A base station (BS) transmits, to a user equipment (UE), a configuration for at least one measurement event to be used for a handover of the UE from a source cell to one of a set of neighbor cells, wherein the configuration includes at least a configured rank criterion for triggering a measurement report in response to the measurement event. The BS receives, from the UE, the measurement report based on the configuration, the measurement report at least including a measured rank value for one or more reported cells in the set. The BS selects a target cell from the reported cells for the handover based at least on the received measured rank values, and transmits a handover command to the UE for the handover to the selected target.

Abstract: Methods and techniques are described for supporting location services for a user equipment (UE) in a Fifth Generation wireless network in which a base station, such as a gNB or ng-eNB, broadcasts a Positioning Reference Signal (PRS) in a plurality of different directions and at a plurality of different times. A PRS muting configuration is used in which PRS is muted using a time based and angle based pattern to prevent interference between beams transmitted by other base stations and/or to prevent interference between beams transmitted simultaneously by a single base station. The time based and angle based muting pattern, for example, may provide an indication for each direction in the plurality of different directions and for each time in the plurality of different times and as to whether the PRS is transmitted or muted by the base station.

Abstract: A User Equipment (UE) may receive a coverace mode transition request at a first time and upon determining that the coverage mode transition request includes a request to transition to an Enhanced Coverage (EC) mode, the UE may determine, based on parameters in the coverage mode transition request, an expected communication delay for transmission of a Reference Signal Time Difference (RSTD) measurement report The UE may initiate transmission of the RSTD measurement report for the positioning measurement session at a second time not exceeding a specified RSTD measurement time. The second time may precede an RSTD measurement timeout time for the positioning measurement session by at least the expected communication delay. Disclosed embodiments also pertain to communication of the expected communication delay between a Location Server (e.g. Evolved Serving Mobile Location Center) and a Base Station (e.g. evolved NodeB) using Long Term Evolution Positioning Protocol Annex (LPPa) messages.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications. In some aspects, a wireless communication device may determine that a first component carrier (CC), associated with a first communications chain of one or more components of the wireless communication device, has a lower throughput than a second CC associated with a second communications chain of the one or more components, wherein the second communications chain selectively receives a signal of a feedback receiver of a component of the one or more components. The wireless communication device may configure the one or more components of the wireless communication device to receive first communications of the first CC on the second communications chain and to receive second communications of the second CC on the first communications chain based at least in part on determining that the first CC has a lower throughput than the second CC.
