Multi-hop communications in a wireless network
First Claim
1. A method of scheduling communications, comprising:
- selecting first and second terminal pairs, the first terminal pair having a first transmitting terminal and a first receiving terminal, and the second terminal pair having a second transmitting terminal and a second receiving terminal;
determining whether a first direct signal transmission from the first transmitting terminal to the first receiving terminal simultaneously with a second direct signal transmission from the second transmitting terminal to the second receiving terminal does not satisfy both a target quality parameter for the first receiving terminal and a target quality parameter for the second receiving terminal;
scheduling, based on the determining step, a first signal transmission from the first transmitting terminal to an intermediate terminal, the first signal transmission being destined for the first receiving terminal;
scheduling, simultaneously with the first signal transmission, a second signal transmission from the second transmitting terminal to the second receiving terminal; and
scheduling a power level for each of the first and second signal transmission that satisfies a target quality parameter for the intermediate terminal and the target quality parameter of the second receiving terminal.

12. A communications terminal, comprising:
a scheduler configured to select first and second terminal pairs, the first terminal pair having a first transmitting terminal and a first receiving terminal, and the second terminal pair having a second transmitting terminal and a second receiving terminal, the scheduler being further configured to schedule a first signal transmission from the first transmitting terminal to an intermediate terminal, the first signal transmission being destined for the first receiving terminal, schedule, simultaneously with the first signal transmission, a second signal transmission from the second transmitting terminal to the second receiving terminal, and schedule a power level for each of the first and second signal transmissions that satisfies a target quality parameter for each of the intermediate terminal and the second receiving terminal, wherein the scheduler is farther configured to schedule the first signal transmission if a direct signal transmission from the first transmitting terminal to the first receiving terminal, simultaneously with the second signal transmission, does not satisfy both a target quality parameter for the first receiving terminal and the target quality parameter for the second receiving terminal. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
