Channel measurement techniques in discontinuous reception scenarios
摘要
說明書
Some wireless communications systems may have transmissions between a user equipment (UE) and a base station that are performed according to a discontinuous reception (DRX) configuration (e.g., a connected mode DRX (CDRX) configuration) in which the UE transitions to a power-saving inactive state between ON-durations in which the UE is in an active mode to monitor for communications from the base station or transmit communications to the base station. In some cases, a DRX configuration may result in the UE having an inactive state during periods in which the base station may transmit one or more reference signals (e.g., channel state information reference signals (CSI-RSs)) for use in channel measurements at the UE. In such cases, if the UE remains in the inactive state, channel measurements of the UE may become stale resulting in a lower likelihood of successful communications between the UE and the base station. Further, if the UE were to maintain an active mode in order to receive and measure such reference signals, power consumption is increased. Various aspects of the present disclosure provide techniques for UE measurements of reference signals that are transmitted during a scheduled DRX inactive state of a UE.
