Title:
WIRELESS COMMUNICATION SYSTEM, WIRELESS DEVICE, TERMINAL, AND WIRELESS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2013/011763
Kind Code:
A1
Abstract:
The present invention, which comprises N service areas (where N is a natural number greater than 2) to which the same cell identification number is assigned, a wireless device further comprising a transmission antenna, at least one such device being included in the respective N service areas, and a terminal which communicates with the wireless device in the service areas, is applied to a wireless communication system in which the N service areas overlap wholly or partially. At least one of the wireless devices further comprises a notification means for notifying the terminal of a combination of the transmission antennae. The terminal further comprises a feedback means for sending feedback of transmission path ancillary information which is derived using the transmission antenna combination about which notification is provided from the notification means.
