Abstract

In the field of wireless communication networks or systems in which a user equipment is configured with semi-persistent scheduling, a first aspect of the invention provides for continuous or non-interrupted SPS of the user equipment after a handover, and a second aspect of the invention provides an enhanced control signaling for a user equipment configured with SPS to reduce the signaling overhead.
