Apparatus and method for allocating communication resources in a communication system
View Patent ↗An apparatus, method and system for allocating communication resources in a communication system. In one embodiment, an apparatus includes a processor 520 and memory 550 including computer program code. The memory 550 and the computer program code are configured to, with the processor 520 , cause the apparatus to compute a transmitter power level for a user equipment on a communication resource allocated to a neighboring base station to limit interference for communications in an area served by the neighboring base station below a first threshold level, compute a signal-to-interference-and-noise ratio for an uplink communication by the user equipment employing the transmitter power level on the communication resource within an area served by the apparatus, and assign a subframe of the communication resource to the user equipment if the signal-to-interference-and-noise ratio for the uplink communication is greater than a second threshold level.
1. An apparatus, comprising:
a processor; and
memory including computer program code,
said memory and said computer program code configured to, with said processor, cause said apparatus to perform at least the following:
compute a transmitter power level for a user equipment on a communication resource allocated to a neighboring base station to limit interference for communications in an area served by said neighboring base station below a first threshold level;
compute a signal-to-interference-and-noise ratio for an uplink communication by said user equipment employing said transmitter power level on said communication resource within an area served by said apparatus; and
assign a subframe of said communication resource to said user equipment if said signal-to-interference-and-noise ratio for said uplink communication is greater than a second threshold level.
2. The apparatus as recited in claim 1 wherein said memory and said computer program code are further configured to, with said processor, cause said apparatus to assign said subframe of said communication resource to said user equipment if a path loss from said user equipment to said apparatus is less than a path loss threshold level.
3. The apparatus as recited in claim 1 wherein said memory and said computer program code are further configured to, with said processor, cause said apparatus to compute said transmitter power level for said user equipment on said communication resource based on a path loss to said neighboring base station.
4. The apparatus as recited in claim 1 wherein said memory and said computer program code are further configured to, with said processor, cause said apparatus to receive information about said communication resource and said subframe from said user equipment.
5. The apparatus as recited in claim 1 wherein said communication resource is not allocated to said apparatus.
6. The apparatus as recited in claim 1 wherein said signal-to-interference-and-noise ratio for said uplink communication is dependent on a path loss from said user equipment to said apparatus and interference on said communication resource observed by said apparatus.
7. A computer program product comprising a program code stored in a non-transitory computer readable medium configured to:
compute a transmitter power level for a user equipment on a communication resource allocated to a neighboring base station to limit interference for communications in an area served by said neighboring base station below a first threshold level;
compute a signal-to-interference-and-noise ratio for an uplink communication by said user equipment employing said transmitter power level on said communication resource within an area served by said apparatus; and
assign a subframe of said communication resource to said user equipment if said signal-to-interference-and-noise ratio for said uplink communication is greater than a second threshold level.
8. A method, comprising:
computing a transmitter power level for a user equipment on a communication resource allocated to a neighboring base station to limit interference for communications in an area served by said neighboring base station below a first threshold level;
computing a signal-to-interference-and-noise ratio for an uplink communication by said user equipment employing said transmitter power level on said communication resource within an area served by said apparatus; and
assigning a subframe of said communication resource to said user equipment if said signal-to-interference-and-noise ratio for said uplink communication is greater than a second threshold level.
9. The method as recited in claim 8 further comprising assigning said subframe of said communication resource to said user equipment if a path loss from said user equipment to a serving base station is less than a path loss threshold level.
10. The method as recited in claim 8 further comprising compute said transmitter power level for said user equipment on said communication resource based on a path loss to said neighboring base station.
11. The method as recited in claim 8 further comprising receiving information about said communication resource and said subframe from said user equipment.
12. The method as recited in claim 8 wherein said signal-to-interference-and-noise ratio for said uplink communication is dependent on a path loss from said user equipment to a serving base station and interference on said communication resource observed by said serving base station.
