Abstract

A method and apparatus are provided to reduce interference in neighbor cells by limiting the uplink power of an interfering mobile terminal In this regard, a method is provided that includes generating a measurement report, wherein the measurement report includes interference measurement information measured from at least one neighbor cell. The method also includes causing the generated measurement report to be transmitted to a receiving station. The method may also include receiving a power level indication from the receiving station, wherein the indication causes a modification of transmission power.

Claims (44)

1 . A method comprising:

generating, using a processor, a measurement report, wherein the measurement report includes interference measurement information measured from at least one neighbor cell;

causing the generated measurement report to be transmitted to a receiving station; and

receiving a power level indication from the receiving station, wherein the indication causes a modification of transmission power.

2 . A method of claim 1 , wherein the receiving station is at least one of an access point and a radio network controller.

3 . A method of claim 1 , wherein generating a measurement report further comprises determining at least one of an uplink power headroom, a current serving grant, a listing of neighbor cells, and a neighbor cell interference information.

4 . A method of claim 1 , wherein generating a measurement report further comprises determining uplink interference information from at least one neighbor cell associated with a neighbor cell list.

5 . A method comprising:

receiving a measurement report from a reporting station;

determining, using a processor, neighbor cell interference information based on the received measurement information; and

causing a serving grant to be modified for a mobile terminal.

6 . A method of claim 5 , wherein causing a serving grant to be modified further comprises causing at least one of a mobile terminal's enhanced dedicated channel “E-DCH” power allocation and scheduling of the mobile terminal to be modified.

7 . A method of claim 5 , wherein the reporting station is a mobile terminal.

8 . A method of claim 7 , further comprising

receiving, from the mobile terminal, uplink interference information read from at least one of system information block 7 or system information block 5 of the neighbor cells associated with the neighbor cell list; and

receiving, from the mobile terminal, at least one of a current serving grant, a listing of neighbor cells, and a neighbor cell interference information with the received measurement report.

9 . A method of claim 5 , wherein the reporting station includes at least one mobile terminal and an at least one access point.

10 . A method of claim 9 , further comprising:

receiving a measurement report from the access point; and

receiving from the mobile terminal at least one of an uplink power headroom, a current serving grant, a listing of neighbor cells, and a neighbor cell interference information with the received measurement report.

11 . An apparatus comprising:

at least one processor; and

at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:

generate a measurement report, wherein the measurement report includes interference measurement information from at least one neighbor cell;

cause the generated measurement report to be transmitted to a receiving station; and

receive a power level indication from the receiving station, wherein the indication results in a modified uplink power level.

12 . An apparatus according to claim 11 , wherein the receiving station is at least one of an access point and a radio network controller.

13 . An apparatus according to claim 11 , wherein the at least one memory including the computer program code is further configured to, with the at least one processor, cause the apparatus to determine at least one of an uplink power headroom, a current serving grant, a listing of neighbor cells, and a neighbor cell interference information.

14 . An apparatus according to claim 11 , wherein the at least one memory including the computer program code is further configured to, with the at least one processor, cause the apparatus to determine uplink interference information from at least one neighbor cell associated with a neighbor cell list.

15 . An apparatus comprising:

at least one processor; and

at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:

receive a measurement report from a reporting station;

determine neighbor cell interference information based on the received measurement information; and

cause a serving grant to be modified for a mobile terminal.

16 . An apparatus according to claim 15 , wherein the at least one memory including the computer program code is further configured to, with the at least one processor, cause the apparatus to cause at least one of a mobile terminal's enhanced dedicated channel “E-DCH” power allocation and scheduling of the mobile terminal to be modified.

17 . An apparatus according to claim 15 , wherein the reporting station is a mobile terminal.

18 . An apparatus according to claim 17 , wherein the at least one memory including the computer program code is further configured to, with the at least one processor, cause the apparatus to

receive, from the mobile terminal, uplink interference information from at least one neighbor cell associated with the neighbor cell list; and

receive, from the mobile terminal, at least one of a current serving grant, a listing of neighbor cells, and neighbor cell interference information with the received measurement report.

19 . An apparatus according to claim 15 , wherein the reporting station includes at least one mobile terminal and an at least one access point.

20 . An apparatus according to 19 , wherein the at least one memory including the computer program code is further configured to, with the at least one processor, cause the apparatus to

receive a measurement report from the access point; and

receive from the mobile terminal at least one of a current serving grant, a listing of neighbor cells, and a neighbor cell interference information with the received measurement report.
