Method and device for allocating common channel resources

摘要

A resource allocation method and device are provided that can achieve uniform loads on and stable quality of a common channel available to mobile stations having no dedicated channels. A method for allocating common channel resources in a system in which a plurality of first radio communication devices transmit data to a second radio communication device over a common channel, based on first resource allocation information, includes: by the second radio communication device, transmitting second resource allocation information to at least one of the first radio communication devices; and by each of the first radio communication devices, transmitting data to the second radio communication device over the common channel, based on any one of the first resource allocation information and the second resource allocation information.

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.
