US 2017/0290023 A1 · INTER-NETWORK INTERFERENCE COORDINATION METHOD

Abstract

Disclosed is a network interference coordination method in a co-primary spectrum sharing scenario. The method comprises the following steps: a first network and a second network negotiate an inter-network shared band, the shared band being in a shared spectrum pool; the first network evaluates inter-network interference; the first network determines whether to perform internal coordination, if internal coordination is performed, the first network performs internal coordination; if internal coordination is not performed, request the second network to perform inter-network interference coordination; the second network determines whether to perform internal coordination, if internal coordination is performed, the second network performs internal coordination; and if internal coordination is not performed, go back to the step of negotiating, by a first network and a second network, an inter-network shared band. The present invention can fairly and properly implement inter-network interference coordination in the co-primary spectrum sharing scenario.

1-20. (canceled)

A network interference coordination method for a first network and a second network which share a shared spectrum pool with the same priority, comprising the following steps:

a step that the first network and the second network negotiate about an inter-network shared frequency band, wherein the shared frequency band is in the shared spectrum pool;
a step that the first network evaluates inter-network interference;
a step that one network of the first network and the second network judges whether to execute internal coordination, if internal coordination can be executed, then the one network executes internal coordination, if internal coordination cannot be executed, then the one network request an another network to conduct inter-network interference coordination;
a step that the another network judges whether to execute internal coordination, if internal coordination can be executed, then the another network executes internal coordination;
and if internal coordination cannot be executed, then turn to the step of “the first network and the second network negotiate about an inter-network shared frequency band”.
