Abstract
A radio access network having multiple sectors comprises two or more sector transmitters serving respective sectors for transmitting data to mobile stations; a plurality of antennas, each antenna assigned to a respective sector transmitter; and a antenna management processor controlling sector antenna assignments and operative to dynamically reassign a sector antenna associated with a sector transmitter in a first sector to a sector transmitter in a second sector.
Claims26
A radio access network including multiple sectors comprising:
- two or more sector transmitters serving respective sectors for transmitting data to mobile stations;
- a plurality of antennas, each antenna assigned to a respective sector transmitter;
- and
- an antenna management processor controlling sector antenna assignments and operative to dynamically reassign a sector antenna associated with a sector transmitter in a first sector to a sector transmitter in a second sector.
The radio access network of 5 wherein the scheduler jointly schedules the sector antennas.
A method implemented in a radio access network having two or more sector transmitters for transmitting data to mobile stations, said method comprising:
- assigning each one of a plurality of sector antennas to a respective sector transmitter;
- and
- dynamically reassigning a sector antenna associated with a sector transmitter in a first sector to a sector transmitter in a second sector.
The method of 17 wherein scheduling transmissions to said mobile stations over said shared packet data channel comprises scheduling mobile stations to receive packet data transmissions over said shared packet data channel one at a time using all assigned sector antennas.
The method of 17 wherein scheduling transmissions to said mobile stations over said shared packet data channel comprises scheduling two or more mobile stations to receive packet data transmissions over said packet data channel at one time.
