Scheduling transmission of data at a base station based on an interference indicator message from another base station

摘要

A system includes a first base station of a first vendor configuration and a second base station of a second vendor configuration. A link is between the first and second base stations. The first base station is configured to receive at least one interference indicator message from the second base station, and schedule transmission of data based on the at least one interference indicator message. Scheduling the transmission of data includes determining whether to transmit the data using a current resource or to delay transmission of the data.

1. A system comprising:
a first base station of a first vendor configuration; a second base station of a second vendor configuration; and a link between the first and second base stations, wherein the first base station is configured to:
receive at least one interference indicator message from the second base station, andschedule transmission of data between the first base station and a mobile station based on the at least one interference indicator message, wherein scheduling the transmission of the data between the first base station and the mobile station includes determining whether to delay transmission of the data between the first base station and the mobile station for a period of time, wherein the period of time to delay transmission of data between the first base station and the mobile station is a randomly generated delay time period; and at least one additional base station and a second link between the first base station and the at least one additional base station; wherein scheduling transmission of the data is further based on the at least one interference indicator message from the at least one additional base station wherein the first base station is further configured to:
receive at least one interference indicator message from the at least one additional base station; andcalculate an interference decision metric based on interference indicator values in the interference indicator messages;compare the calculated interference decision metric to a threshold;schedule transmission of the data in the current resource if the calculated interference decision metric has a first relation to the threshold; anddelay transmission of the data if the calculated interference decision metric has a second, different relation to the threshold.
