Abstract

An apparatus in a Base station (BS) and an apparatus in a Mobile Station (MS) are provided for allocating and requesting, respectively, uplink resources in a wireless communication system. The apparatus in the MS includes a transmitter for sending, to a base station, a predetermined Channel Quality Information CHannel (CQICH) codeword over a pre-allocated CQICH in a silence period, when an uplink bandwidth for an extended real-time Polling Service (ertPS) is not allocated to the mobile station, to inform the base station that the mobile station has data to send; and a receiver for receiving, from the base station, information related to an uplink bandwidth supporting a maximum rate allocated by the base station, in response to the CQICH codeword

Claims

1. An apparatus in a mobile station for requesting uplink resources in a wireless communication system, the apparatus comprising:

a transmitter for sending, to a base station, a predetermined Channel Quality Information CHannel (CQICH) codeword over a pre-allocated CQICH in a silence period, when an uplink bandwidth for an extended real-time Polling Service (ertPS) is not allocated to the mobile station, to inform the base station that the mobile station has data to send; and

a receiver for receiving, from the base station, information related to an uplink bandwidth supporting a maximum rate allocated by the base station, in response to the CQICH codeword.

2. The apparatus of claim 1, wherein the silence period indicates an off period of the ertPS between the mobile station and the base station.

3. The apparatus of claim 1, wherein the transmitter sends, to the base station, an extended Piggyback Request (PBR) field of a Grant Management SubHeader (GMSH) in a period when the uplink bandwidth for the ertPS is allocated to the mobile station, in order to request a change of the uplink bandwidth for the ertPS.

4. The apparatus of claim 1, wherein the transmitter sends, to the base station, a Bandwidth Request (BR) field of a bandwidth request and an uplink transmit power report header in a period when the uplink bandwidth for the ertPS is allocated to the mobile station, in order to request a change of the uplink bandwidth for the ertPS.

5. An apparatus in a base station for allocating uplink resources in a wireless communication system, the apparatus comprising:

a receiver for receiving, from a mobile station, in a silence period, when an uplink bandwidth for an extended real-time Polling Service (ertPS) is not allocated to the mobile station, a predetermined Channel Quality Information CHannel (CQICH) codeword over a pre-allocated CQICH, the CQICH codeword informing the base station that the mobile station has data to send; and

a transmitter for transmitting, to the mobile station, an allocation information on an uplink bandwidth supporting a maximum rate, in response to the CQICH codeword.

6. The apparatus of claim 5, wherein the silence period indicates an off period of the ertPS between the mobile station and the base station.

7. The apparatus of claim 5, wherein the receiver receives, from the mobile station, an extended Piggyback Request (PBR) field of a Grant Management SubHeader (GMSH) in a period when the uplink bandwidth for the ertPS is allocated to the mobile station, to request a change of the uplink bandwidth for the ertPS.

8. The apparatus of claim 5, wherein the receiver receives, from the mobile station, a Bandwidth Request (BR) field of a bandwidth request and an uplink transmit power report header in a period when the uplink bandwidth for the ertPS is allocated to the mobile station, to request a change of the uplink bandwidth for the ertPS.
