UPLINK SYNCHRONIZATION WITH MULTIPLE TIMING ADVANCES IN A WIRELESS COMMUNICATION ENVIRONMENT

摘要

Technology for synchronization of uplink transmission with multiple timing advances in a wireless communication environment is disclosed. Additional resource allocation messages for additional timing advances are addressed to a user equipment specific search space. A number of band decodes needed to find a resource allocation message used to access an additional timing advance can be reduced by padding the resource allocation message. A number of blind decodes used to find the resource allocation message can also be reduced by restricting the control channel candidates in which the resource avocation can be embedded in terms of the control channel element aggregation level, or levels, associated with acceptable control channel candidates.
