Abstract
An apparatus for storing handover information in a mobile communication system is provided. The apparatus includes an estimation unit configured to estimate a direction of arrival (DOA) of a received signal with respect to a first base station based on the received signal, the received signal being received from a terminal belonging to the first base station, and a storage unit to store the estimated DOA as handover information associated with a second base station when the terminal is handed over to the second base station.
Claims36
An apparatus for storing handover information in a mobile communication system, the apparatus comprising:
- an estimation unit configured to estimate a direction of arrival (DOA) of a received signal with respect to a first base station based on the received signal, the received signal being received from a terminal served by the first base station;
- and
- a storage unit configured to:
- compare the estimated DOA with an average of pre-stored handover information associated with a second base station;
- and
- store, when the terminal is handed over to the second base station and depending on the result of the comparison, the estimated DOA with the handover information.
An apparatus for storing handover information in a mobile communication system, the apparatus comprising:
- a storage unit configured to:
- compare the direction of arrival (DOA) of a received signal with an average of pre-stored handover information regarding a first base station's particular region of coverage, and
- store, depending on the result of the comparison, the DOA with the handover information;
- and
- a transmission unit configured to broadcast the stored handover information to the particular region.
An apparatus for storing handover information in a mobile communication system, the apparatus comprising:
- a storage unit configured to:
- divide coverage of a first base station into a plurality of regions,
- compare, for each region, the direction of arrival (DOA) of a signal received from the region with an average of pre-stored handover information about the region, and
- store, depending on the result of the respective comparison, the respective DOA with the handover information about the region;
- and
- a transmission unit configured to:
- broadcast the stored handover information for each of the regions, respectively;
- and
- perform beamforming with respect to the handover information based on a direction of each of the regions with respect to the first base station or wireless channel quality information associated with each of the regions.
A method of storing handover information in a mobile communication system, the method comprising:
- estimating a direction of arrival (DOA) of a received signal with respect to a first base station based on the received signal, the received signal being received from a terminal served by the first base station;
- comparing the estimated DOA with an average of pre-stored handover information associated with a second base station;
- and
- storing, when the terminal is handed over to the second base station and depending on the result of the comparison, the estimated DOA with the handover information.
A method of storing handover information in a mobile communication system, the method comprising:
