Abstract
A method and apparatus for allocating a ranging channel for a synchronized mobile station in a wireless communication system is provided. A base station (BS) allocates the ranging channel for the synchronized mobile station in a first subframe and a first subband. An index of the first subframe and an index of the first subband are determined respectively based on an index of a second subframe and an index of a second subband in which a ranging channel of a non-synchronized mobile station is allocated.
Claims18
A method of allocating a ranging channel for a synchronized mobile station in a wireless communication system, the method comprising:
- allocating, by a base station, the ranging channel for the synchronized mobile station in a first subframe and a first subband,
- wherein the first subframe is determined using a mod(OSF+1,NUL)th uplink subframe,
- wherein OSF denotes a subframe offset of a ranging channel for a non-synchronized mobile station, and
- wherein NUL denotes a number of uplink subframes per frame.
An apparatus for allocating a ranging channel for a synchronized mobile station in a wireless communication system, the apparatus comprising:
- a radio frequency (RF) unit for transmitting or receiving a radio signal;
- and
- a processor coupled to the RF unit and configured to allocate the ranging channel for the synchronized mobile station in a first subframe and a first subband,
- wherein the first subframe is determined using a mod(OSF+1,NUL)th uplink subframe,
- wherein OSF denotes a subframe offset of a ranging channel for a non-synchronized mobile station, and
- wherein NUL denotes a number of uplink subframes per frame.
A method of ranging for a synchronized mobile station in a wireless communication system, the method comprising:
- receiving, by the synchronized mobile station, ranging channel information from a base station;
- and
- ranging, by the synchronized mobile station, on the base station through a ranging channel for the synchronized mobile station in a first subframe and a first subband,
- wherein the first subframe is determined using a mod(OSF+1, NUL)th uplink subframe,
- wherein OSF denotes a subframe offset of a ranging channel for a non-synchronized mobile station, and
- wherein NUL denotes a number of uplink subframes per frame.
