SELECTING ANTENNAS IN DOWNLINK COOPERATIVE SCHEDULING
First Claim
1. A method for obtaining a set of selected antennas in a mobile communication network, wherein each one of the selected antennas is intended to be used in data transmissions to a first mobile communication terminal, the method being performed in a network node of the mobile communication network and comprising the steps of:
- obtaining a set of candidate antennas, wherein each one of the candidate antennas is arranged to send out the same cell identifier and at least some of the candidate antennas have different coverage areas;
evaluating performance of at least a subset of the candidate antennas in relation to the first mobile communication terminal; and
determining a set of selected antennas based on the performance of the candidate antennas having been evaluated;
wherein the step of evaluating performance comprises, for antenna groups each comprising one or more of the candidate antennas, the substeps of;
transmitting data using the respective candidate antennas of the antenna group, for one antenna group at a time; and
determining a performance related to the transmitted data by evaluating any acknowledgement or non-acknowledgement signals, related to the transmitted data, received from the first mobile communication terminal.
