摘要： User equipment (UE) transmits an access response to a random access procedure (RACH) preamble message to acquire an uplink grant from a node of a wireless communication system. The access response provides an uplink grant to the UE for a request for authorization to transmit uplink data to the node. In response to determining that the access response message provides an uplink grant sufficient to empty the UE's data buffer, the UE transmits the request for authorization including the uplink data to the node. The UE can then terminate the RACH procedure without requiring any subsequent uplink grant from the node, having accomplished successful data transmission using the request for authorization.
