摘要： Embodiments of the present disclosure are directed toward devices and methods for fast radio link recovery in cellular networks. In one embodiment, the signal strength of the serving cell is compared to the signal strength of a target cell, and a radio link failure (RLF) timer is terminated or shortened based on the comparison. Alternatively, a second shorter timer may be used as opposed to modifying the current timer. In some embodiments, the modification of RLF timers may be triggered by the start of a measurement trigger timer. This may allow a user equipment to more quickly establish a connection with a target cell in situations where radio link failure or handover failure are likely to occur. In some instances, the parameters for terminating or shortening the radio link failure timer, or starting an additional timer, may be provided to the user equipment by a network.

摘要： Embodiments of user equipment (UE) and method for adaptively selecting an A3offset-TTT pair for handover in a wireless access network are generally described herein. In some embodiments, the UE may select an A3offset value based on target cell Reference Signal Received Power (RSRP) and select a time-to-trigger (TTT) based on serving cell RSRP. A measurement report may be transmitted to an eNodeB for handover when the target cell RSRP exceeds the serving cell RSRP by at least the A3offset value for the TTT. The A3offset value may be selected to be inversely related to the target cell RSRP and the TTT may be selected to be directly related to the serving cell RSRP.

摘要： A UE may decode a radio-resource control (RRC) reconfiguration message comprising a conditional handover (CHO) configuration (CHO-Config) which may identify a CHO configuration for at least one target candidate cell. The CHO configuration may include two or more CHO triggering events for an entry condition. The UE may monitor measurement quantities of the target candidate cell for the entry condition to determine if any of the CHO triggering events are met, start a first count-down timer when the entry condition of a first of the CHO triggering events is met and start a second count-down timer when the entry condition of a second of the CHO triggering events is met. The UE may apply the CHO configuration to the target candidate cell when both of the two CHO triggering events remain fulfilled upon expiration of the both timers.

摘要： Embodiments of a Next Generation Node-B (gNB) and User Equipment (UE) are generally described herein. The gNB may transmit control signaling to configure transmission of position reference signals (PRSs) by a plurality of transmit-receive points (TRPs). The gNB may receive, from the UE, for each of the TRPs, a set of signal location parameters (SLPs). The gNB may perform an iterative process to estimate a position of the UE. For a current iteration, the gNB may: determine a current estimate of the position of the UE based on a current plurality of sets of SLPs; and determine a cost function for each of the current plurality of sets of SLPs. The gNB may determine, based on the cost functions, a next plurality of sets of SLPs for a next estimate of the position of the UE.
