Abstract
A bandwidth request procedure is performed in a wireless communication system by transmitting a bandwidth request indicator and a bandwidth request message through a bandwidth request channel; receiving an uplink grant message indicating uplink radio resource in response to the bandwidth request indicator and the bandwidth request message; and transmitting uplink data after receiving the uplink grant message, wherein the uplink grant message includes information regarding the type of the uplink grant message.
Claims4
A method of performing a bandwidth request (BR) to a base station (BS) in a wireless communication system, the method performed comprising:
- determining, by a terminal, whether to perform a first type BR procedure or a second type BR procedure based on a type of a service provided by the BS, wherein the first type BR procedure is associated with a non-real time service and the second type BR procedure is associated with a real time service;
- selecting, by the terminal, a first BR sequence among a first subset of available orthogonal sequences if the first type BR procedure is determined to be performed;
- selecting, by the terminal, a second BR sequence among a second subset of the available orthogonal sequences if the second type BR procedure is determined to be performed;
- transmitting, from the terminal to the BS, the first BR sequence if the first type BR procedure is determined to be performed;
- and
- transmitting, from the terminal to the BS, the second BR sequence and a first BR message comprising data associated with the BR if the second type BR procedure is determined to be performed,
- wherein the first BR message further comprises a first cyclic redundancy check (CRC) for error detection.
