Claim Text:
1. A method for resource allocation in a system comprising a plurality of first radio communication devices capable of performing data transmission to a second radio communication device, the method comprising: transmitting resource allocation information from the second radio communication device to one first radio communication device of the plurality of first radio communication devices, wherein the resource allocation information comprises dedicated resource allocation information; if the one first radio communication device receives an acknowledgement from the second radio communication device in response to the one first radio communication device sending a preamble signature, the one first radio communication device performing a first data transmission using a default transmission profile; if the one first radio communication device receives a negative acknowledgement from the second radio communication device in response to the one first radio communication device sending the preamble signature, and the one first radio communication device does not receive the dedicated resource allocation information with the negative acknowledgement, the one first radio communication device performing a preamble signature retransmission to the second radio communication device; and if the one first radio communication device receives the negative acknowledgement from the second radio communication device and the one first radio communication device receives the dedicated resource allocation information with the negative acknowledgement, the one first radio communication device performing a second data transmission using the dedicated resource allocation information, the second data transmission being different from the preamble signature retransmission.
