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 an amount of data remaining to be transmitted between the first terminal pair and the second terminal pair and selecting a first data rate for the first terminal pair and a second data rate for the second terminal pairs; and
determining whether a first direct signal transmission from the first transmitting terminal to the first receiving terminal at the first data rate simultaneously with a second direct signal transmission from the second transmitting terminal to the second receiving terminal at the second data rate satisfies a target quality parameter for the first receiving terminal and a target quality parameter for the second receiving terminal, if the target quality parameters for both the first receiving terminal and the second receiving terminal are not satisfied then scheduling a first signal transmission from the first transmitting terminal to an intermediate terminal, the first signal transmission being destined for the first receiving terminal.

Abstract
Systems and techniques are disclosed relating to wireless communications. The systems and techniques involve wireless communications wherein a module or communications device is 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, 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.
