Abstract

Allocating radio resources in a mobile communication system, comprises transmitting first information to a network, wherein the first information is utilized by the network to allocate radio resources to a mobile terminal for allowing communication between the mobile terminal and the network, and receiving second information from the network, wherein the second information is related to an allocation of radio resources for the mobile terminal.

Claims

1. A method for allocating radio resources in a mobile communication system, the method performed by a mobile terminal and comprising:

transmitting first information to a network, wherein the first information is utilized by the network to allocate radio resources to a mobile terminal for allowing communication between the mobile terminal and the network; and

receiving second information from the network, wherein the second information is related to an allocation of radio resources for the mobile terminal,

wherein the first information is transmitted upon expiration of a timer or upon receiving a request to transmit the first information from the network,

wherein the first information comprises information related to an average number of retransmissions under a hybrid automatic repeat request (HARQ) scheme and mobile terminal power information comprising an amount of power available for use by the mobile terminal,

wherein the second information is received during a first frame of a set of time frames, wherein the first frame includes identities of all mobile terminals that are scheduled for data communication within the set of time frames, and

wherein the second information comprises at least an indicator for indicating to the mobile terminal the existence of paging information or information related to when the network can allocate the radio resources.

2. The method of claim 1, wherein the mobile terminal is periodically allocated radio resources for transmitting the first information using the allocated radio resources.

3. The method of claim 1, wherein the second information is received along with a NACK signal from the network, wherein the network transmits the NACK signal upon incorrectly receiving data from the mobile terminal.

4. The method of claim 1, wherein a mobile terminal is in an inactive state during the other time frames of the set of time frames if the identity of the mobile terminal is not included in the first frame.

5. The method of claim 1, wherein the second information comprises information related to when the mobile terminal can transmit the first information.

6. The method of claim 1, wherein the first information is transmitted on a portion of a random access channel the mobile terminal is allowed to use.

7. A method for allocating radio resources in a mobile communication system, the method performed by a network and comprising:

receiving first information from a mobile terminal, wherein the first information is utilized by the network to allocate radio resources to the mobile terminal for allowing communication between the mobile terminal and the network; and

transmitting second information to the mobile terminal, wherein the second information is related to an allocation of radio resources for the mobile terminal,

wherein the first information is received upon expiration of a timer or upon transmitting a request for the first information to the mobile terminal,

wherein the first information comprises information related to an average number of retransmissions under a hybrid automatic repeat request (HARQ) scheme and mobile terminal power information comprising an amount of power available for use by the mobile terminal,

wherein the second information is transmitted during a first frame of a set of time frames, wherein the first frame includes identities of all mobile terminals that are scheduled for data communication within the set of time frames, and

wherein the second information comprises at least an indicator for indicating to the mobile terminal the existence of paging information or information related to when the network can allocate the radio resources.

8. The method of claim 7, wherein the mobile terminal is periodically allocated radio resources for transmitting the first information using the allocated radio resources.

9. The method of claim 7, wherein the second information is transmitted along with a NACK signal from the network, wherein the network transmits the NACK signal upon incorrectly receiving data from the mobile terminal.

10. The method of claim 7, wherein the mobile terminal is in an inactive state during the other time frames of the set of time frames if the identity of the mobile terminal is not included in the first frame.

11. The method of claim 7, wherein the first information is received on a portion of a random access channel the mobile terminal is allowed to use.
