METHOD AND NETWORK ENTITY FOR REDUCING INTER-NETWORK INTERFERENCE
First Claim
Patent Images
1. A method, on a network entity of a first wireless network, the method comprising:
- communicating with a first User Equipment (“
UE”
) that is connected to the first wireless network;
receiving, from a second wireless network, information regarding the location of a second UE connected a second wireless network;
determining the distance between the first UE) and the second UE;
based on the determined distance, determining the level of interference that the first UE would cause to the second UE;
determining an amount by which the first UE needs to reduce its transmit power in order to bring the determined interference to a predetermined level; and
granting the first UE permission to reduce its transmit power by the determined amount.

Abstract
Wireless networks share UE location information in order to identify possible inter-network aggressors. If a first network determines, based on the location data it receives from a second network, that one of the first network'"'"'s UEs may cause excessive interference to one or more of the second network'"'"'s UEs, the first network grants A-MPR to its UE (e.g., by signaling the UE). The first network'"'"'s UE can then lower its transmit power in order avoid interfering with the second network'"'"'s UE.

8. A method, on a first User Equipment (“
- UE”
) connected to a first wireless network, the method comprising;detecting a beacon signal of a second UE that is connected to a second wireless network; determining the distance between the first UE and the second UE based on the beacon signal; based on the determined distance, determining the level of interference the first UE would cause to the second UE if the first UE transmits at a first power level; determining an amount by which the first UE would need to reduce its transmit power in order to bring the determined interference to predetermined level; and lowering the transmit power of the first UE by the determined amount to a second transmit power level. - View Dependent Claims (9, 10, 11, 12, 13)

14. A network entity, operating as part of a first wireless network, the network entity comprising:
-
a network interface configured to; receive, via a backhaul network, signals from a second wireless network; and wherein the signals contain information indicating the location of a User Equipment (“
UE”
) of the second wireless network; anda processor communicatively linked to the network interface and configured to; receive the location information via the network interface; determine the distance between a UE of the first wireless network and a UE of the second wireless network based on the location information; based on the determined distance, determine the level of interference the first UE causes to the second UE; determine an amount by which the first UE needs to reduce its transmit power in order to bring the determined interference to an acceptable level; and grant the first UE permission to reduce its transmit power by the determined amount. - View Dependent Claims (15, 16, 17)
