Abstract
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.
Claims15
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, and
- schedule 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;
- and
- calculate 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;
- and
- delay transmission of the data if the calculated interference decision metric has a second, different relation to the threshold.

A method comprising:
- receiving, by a first base station of a first vendor configuration, at least one interference indicator message from a second base station of a second vendor configuration;
- calculating, by the first base station, an interference decision metric based on the at least one interference indicator message;
- and
- scheduling transmission of data between the first base station and a mobile station based on the interference decision metric, including determining, based on the interference decision metric, 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 the transmission of the data between the first base station and the mobile station is a randomly generated delay time period;
- wherein scheduling the transmission of data comprises:
- scheduling transmission of data in a current resource if the interference decision metric has a first relation to a predefined threshold;
- and
- delay transmission of the data by a predetermined delay if the interference decision metric has a second relation to the predefined threshold.
