Abstract

A method in a wireless communication network infrastructure scheduling entity, including allocating a radio resource to a schedulable wireless communication entity in the wireless communication network, the radio resource allocated based on a maximum power available to the schedulable wireless communication entity for the radio resource allocated, the radio resource allocated based on an interference impact of the schedulable wireless communication entity operating on the radio resource allocated.

Claims

1. A method in a wireless communication network infrastructure scheduling entity, the method comprising:

allocating a radio resource to a schedulable wireless communication entity in the wireless communication network,

the radio resource allocated based on a maximum power available to the schedulable wireless communication entity for the radio resource allocated,

the radio resource allocated based on an interference impact of the schedulable wireless communication entity operating on the radio resource allocated.

2. The method of claim 1, the wireless communication network infrastructure scheduling entity determining the interference impact based on at least one of a transmission waveform type of the schedulable wireless communication entity, rated maximum power of the schedulable wireless communication entity, operational maximum power level of the schedulable wireless communication entity, current operating power level of the schedulable wireless communication entity, bandwidth assignable to the schedulable wireless communication entity, location of the assignable bandwidth in a carrier band, radio frequency distance (pathloss) between the schedulable wireless communication entity and another wireless communications entity, variation in the operational maximum power of the schedulable wireless communication entity for the assigned bandwidth, separation of assigned bandwidth relative to the other wireless communication entity band, radio technology in a band neighboring a band in which the allocated radio resource is located.

3. The method of claim 1, allocating the radio resource to the schedulable wireless communications entity includes assigning a bandwidth size of the allocated resource to the schedulable wireless communications entity.

4. The method of claim 1, allocating the radio resource based on the interference impact includes assigning bandwidth based on radio frequency distance between the schedulable wireless communication entity and the other wireless communications entity.

5. The method of claim 1, allocating the radio resource based on the interference impact includes assigning bandwidth based on power headroom of the schedulable wireless communication entity.

6. The method of claim 1, allocating the radio resource to the schedulable wireless communication entity includes assigning bandwidth in a particular location within a carrier band.

7. The method of claim 1, the scheduler allocating bandwidth nearer an edge of a carrier band when the schedulable wireless communication entity requires less transmit power, and the scheduler allocating bandwidth farther from the edge of the carrier band when the schedulable wireless communication entity requires more transmit power.

8. The method of claim 1,

the scheduler allocating the radio resource to the schedulable wireless communications entity nearer an edge of a carrier band when a radio frequency distance between the schedulable wireless communication entity and the other wireless communications entity is larger, and

the scheduler allocating the radio resource to the schedulable wireless communications entity farther from the edge of the carrier band when the radio frequency distance between the schedulable wireless communication entity and the other wireless communications entity is smaller.
