Patent ID: 8331298

Claim:
An uplink control channel allocation method, the method comprising: allocating, by a device, a first long cyclic prefix; allocating a first valid symbol that is provided after the first long cyclic prefix, and is used to transmit an initial ranging signal or a handover ranging signal; allocating a second long cyclic prefix that is provided after the first valid symbol, allocating a second valid symbol that is provided after the second long cyclic prefix; and is used to transmit a periodic ranging signal or a band request ranging signal; allocating a short cyclic prefix that is provided after the second valid symbol, a length of the short cyclic prefix being shorter than a length of each of the first and second long cyclic prefixes; and allocating a third valid symbol that is provided after the short cyclic prefix and is used to transmit ACK/NACK information or uplink channel sounding information.
