Patent ID: 8873483

Claim:
A method of handling Semi-Persistent Scheduling (SPS) Cell Radio Network Temporary Identifier (C-RNTI) for a mobile device configured with a primary component carrier, at least one secondary component carrier and an SPS C-RNTI in a wireless communication system, the method comprising: performing a Physical Downlink Control Channel (PDCCH) validation process for an SPS information; determining the SPS information is valid if the PDCCH validation process is valid and if the SPS information is received on the primary component carrier rather than received on any of the at least one secondary component carrier; and determining the SPS information is not valid if the PDCCH validation process is valid and if the SPS information is received on any of the at least one secondary component carrier; wherein the primary component carrier is corresponding to a primary cell, and the primary component carrier and the at least one secondary component carrier are supported by carrier aggregation defined by a long term evolution-advanced specification.
