improved communication method and base station system using a distributed antenna improved (EDAS)

摘要

A base (102, eNB) station configured to: communicate via a distributed antenna system improved (EDAS) comprising a plurality of nodes geographically (104) separated wherein each node antenna (104) antennas has a plurality of antenna elements (106); performing a processing based physical layer for each node antenna (104) in a place centralized processing band; make nodes antennas (104) transmit reference signals according to a multiplexing system to enable a user equipment (112) perform a channel estimation for the antenna elements of any one or more of the nodes of antennas (104); and render nodes of antennas (104) transmit signals having synchronization codes in order to enable the user equipment (112) synchronized with the antenna elements (106) of any one or more of the nodes of antennas (104 ), where the synchronization codes are at least one of: divided to include information fields for uniquely identifying a group messaging, the base (102, eNB) and node antenna (104) station, and configured to have a code structure having a space code is divided into a plurality of subspaces to allow the user equipment (112) identify uniquely, group messaging, the base (102, eNB) station and node antenna (104).
