Method and apparatus for multi-radio coexistence on adjacent frequency bands
First Claim
1. A method for a co-scheduler comprising:
- allocating, to a first user equipment uplink, a first set having at least one sub-carrier in a first frequency band, at least one uplink time period, and at least one transmission power parameter;
detecting a second user equipment operating proximal to the first user equipment by;
receiving first location information of a first user equipment from a first base station serving the first user equipment; and
receiving second location information of a second user equipment from a second base station serving the second user equipment;
in response to the detecting, allocating based on the received first location information and second location information, to the first user equipment uplink, a second set having at least one sub-carrier in the first frequency band that is different from the at least one sub-carrier of the first set, at least one uplink time period, and at least one transmission power parameter;
allocating a particular sub-carrier that was part of the first set and not part of the second set during the at least one uplink time period of the second set to a third user equipment that is not operating proximal to the first user equipment;
determining that the second user equipment is no longer operating proximal to the first user equipment; and
in response to the determining, allocating, to the first user equipment uplink, a third set having at least one sub-carrier in the first frequency band, at least one uplink time period, and at least one transmission power parameter, wherein the third set differs from the second set in either the at least one sub-carrier or the at least one transmission power parameter.

Abstract
A method and apparatus for a co-scheduler can mitigate UE-to-UE adjacent carrier frequency band interference by allocating three sets to a first user equipment uplink. Each set has at least one sub-carrier in a first frequency band, at least one uplink time period, and at least one transmission power parameter. The co-scheduler initially allocates the first set. The co-scheduler allocates the second set in response to detecting a second user equipment operating proximal to the first user equipment, and the second set differs from the first set in either at least one sub-carrier or at least one transmission power parameter. The co-scheduler allocates the third set in response to detecting that the second user equipment is no longer operating proximal to the first user equipment, and the third set differs from the second set in either at least one sub-carrier or at least one transmission power parameter.

19. A co-scheduler comprising:
-
a proximal interference assessor for receiving first user equipment location information from a first user equipment operating in a first frequency band having a first serving base station and for receiving second user equipment location information from a second user equipment operating in a second frequency band adjacent to the first frequency band having a second serving base station and determining whether the first user equipment is proximal to the second user equipment; and a time-frequency-power wireless resource allocator, coupled to the proximal interference assessor, for assigning first user equipment uplink resources and power levels as well as second user equipment downlink resources based on the received first user equipment location information and second user equipment location information and for sending the first user equipment uplink resource assignment to the first serving base station and sending the second user equipment downlink resource assignment to the second serving base station. - View Dependent Claims (20, 21, 22)
