Abstract:
A coordinated multipoint (CoMP) transmission radio network is provided. Each cell in the CoMP network may include antenna nodes distributed at different geographical locations and coupled to a common baseband processing unit. When operating a user device in the CoMP network, the device may register with a neighboring baseband unit and may be served using at least one antenna node. The device may receive reference signals from different antenna nodes in its vicinity, compute receive signal strength levels, and report the measurements to the corresponding baseband unit. The baseband unit may then switch appropriate antennas in/out of use based on the measured results. If desired, the device may be served using more than one antenna node that may or may not be part of the same cell.
