An apparatus, method and system for acquisition of an uplink communication resource in a communication system. In one embodiment, the apparatus includes a processor 520, and memory 550 including computer program code configured to, with the processor 520, cause the apparatus to generate a first message indicating that data is ready for transmission on an uplink, initiate a procedure in a Layer 1 (LI) subsystem 530 to acquire an uplink communication resource in response to the first message, receive a second message from the LI subsystem 530 indicating failure to acquire the uplink communication resource, and generate a third message for a radio link control (RLC) subsystem 540 to proceed as if the RLC subsystem 540 transmits an uplink RLC protocol data unit (PDU) in response to the second message. |
