Abstract

A method is provided for detection of an uplink grant for a user agent (UA). The method comprises detecting a semi-persistent scheduling (SPS) activation/reconfiguration signaling over a physical downlink control channel (PDCCH) only during an SPS activation window, wherein the SPS activation window precedes a discontinuous reception (DRX) on-duration by a predetermined amount of time. Also included is a UA comprising a component configured to detect an SPS activation/reconfiguration signaling over a PDCCH only during an SPS activation window, wherein the SPS activation window precedes a DRX on-duration by a predetermined amount of time.
