Method and apparatus for reducing latency of lte uplink transmissions

Abstract

A method and apparatus reduce latency of Long Term Evolution (LTE) uplink transmissions. Configuration information regarding a downlink control information message for a physical uplink shared channel transmission can be transmitted. The downlink control information message can be sent on a physical downlink control channel in a first subframe to a user equipment. The downlink control information message can indicate a plurality of resource assignments in a second subframe for an uplink carrier from which the user equipment selects one resource assignment for transmission on the uplink carrier. The downlink control information message can be cyclic redundancy check scrambled by a radio network temporary identifier that is indicated via higher layers that are higher than a physical layer. A data packet can be received from the user equipment on the physical uplink shared channel in a resource of a selected resource assignment in the second subframe on the uplink carrier. The selected resource assignment can be selected from the plurality of resource assignments.

Dependencies are inferred from the claim text.
