Adaptive transmit power control in a communication network

摘要

Network devices can be configured to implement adaptive power control functionality in a communication network. A power control requestor of a local communication network can calculate a link margin between a neighbor network device of a neighbor communication network and a local network device associated with a least preferred performance measurement. The power control requestor can transmit a power control message including the link margin to request the neighbor network device to vary the transmit power of the neighbor network device. In response to receiving a power control message, a power control responder can use a link margin indicated in the power control message to evaluate the feasibility of reducing the transmit power of the power control responder. The power control responder can transmit a power control response indicating whether it will vary the transmit power.

主权项

1. A method for adaptive transmit power control in a communication network, the method comprising:
identifying, at a first network device of a local communication network, a second network device of the local communication network that is associated with a first performance measurement; determining, at the first network device, a link margin between the second network device and a neighbor network device of a neighbor communication network based, at least in part, on the first performance measurement and a second performance measurement of the neighbor network device; determining to transmit a first power control message from the first network device to request the neighbor network device to vary a transmit power, based, at least in part, on the link margin; receiving, at the first network device, a response message from the neighbor network device indicating whether the neighbor network device will reduce the transmit power; and determining whether to reuse or share a common communication channel between the local communication network and the neighbor communication network based, at least in part, on whether the neighbor network device will reduce the transmit power.
