RADIO CELLS

摘要

A method of providing a region of radio coverage within a wireless telecommunication network and a wireless telecommunication base station operable to provide that region of radio coverage. The base station comprises: transmission apparatus operable to provide a first region of radio coverage on a first radio frequency and a second region of radio coverage on a second radio frequency. The first region of radio coverage comprises a plurality of angularly spaced primary first radio beams and at least one secondary first radio beam. The base station is arranged to transmit the secondary first radio beam at a vertical tilt angle which differs from a tilt angle associated with the plurality of primary first radio beams. The second region of radio coverage comprises at least a primary second radio beam; that primary second radio beam is arranged to radiate from the base station between adjacent angularly spaced primary first radio beams. Aspects recognise that by providing two cells on a carrier, one vertically offset with respect to another, and horizontally offsetting a cell on a second carrier it may be possible to improve overall network performance.

1. A wireless telecommunication base station operable to provide a region of radio coverage within a wireless telecommunication network, said base station comprising:
transmission apparatus operable to provide a first region of radio coverage on a first radio frequency and a second region of radio coverage on a second radio frequency, said first region of radio coverage comprising a plurality of angularly spaced primary first radio beams and at least one secondary first radio beam; said base station being arranged to transmit said secondary first radio beam at a vertical tilt angle which differs from a tilt angle associated with said plurality of primary first radio beams; said second region of radio coverage comprising at least a primary second radio beam; said primary second radio beam being arranged to radiate from said base station between adjacent angularly spaced primary first radio beams, and wherein said base station is operable to set criteria for cell selection by user equipment such that user equipment are encouraged to select a small cell supported by said secondary first radio beam.
