Filter coefficient configuration in new radio systems
Aspects of filtering coefficient configuration operations are described. Some aspects include a user equipment (UE) decoding a measurement configuration information element (IE) including a measurement quantity parameter, a reference signal (RS)-type filter configuration and at least one filter coefficient. In some aspects, the UE filters at least one of a cell measurement result and a beam measurement result, according to the measurement configuration IE.
