Abstract
A method for requesting uplink resources and transmitting data is provided. The method includes being allocated to a BR code from a BS by an MS, and transmitting a BR indicator in a format without an ID of the MS to the BS using the BR code in non-contention mode by the MS. Because contention-based MSs and non-contention-based MSs transmit different uplink allocation request information, unnecessary information transmission is avoided, which is efficient. Also, information specific to each MS can be transmitted in extra resources.
Claims11
A method for requesting uplink allocation using a Bandwidth Request (BR) code index in a Mobile Station (MS), the method comprising:
- being allocated to a BR code from a Base Station (BS);
- transmitting a BR indicator in a format without an Identifier (ID) of the MS to the BS using the BR code in non-contention mode;
- and
- determining not to use the BR code, upon receipt of an invalid BR code through an uplink grant message from the BS.
A method for replying to an uplink allocation request that uses a Bandwidth Request (BR) code index in a Base Station (BS), the method comprising:
- receiving a BR indicator from a Mobile Station (MS);
- determining that the BR indicator is in a non-contention mode format, upon detection of a BR code allocated to the MS by the BS from the BR indicator;
- and
- determining that the BR indicator is in a contention mode format, if the BR code is not detected from the BR indicator;
- and
- transmitting an invalid BR code through an uplink grant message to the MS, when the BR code is allocated to the MS and the BS determines to release the BR code.
A method for transmitting uplink data using a Bandwidth Request (BR) code index in a Mobile Station (MS), the method comprising:
- being allocated to a BR code from a Base Station (BS);
- transmitting a BR indicator in a format without an Identifier (ID) of the MS to the BS using the BR code in non-contention mode;
- and
- transmitting, upon receipt of an uplink grant message, data to the BS through resources allocated by the uplink grant message,
- wherein, if an invalid BR code is received from the BS through the uplink grant message, the MS determines not to use the BR code.
