Problems solved by technology

However, existing repeater solutions for both coverage gap filling and hotspots only communicate with a single base station
In the case of two or more repeaters connected to different base stations close to a common cell border, using the same frequency carrier, the resulting inter-cell, inter-repeater interference reduces the efficiency of the system

Abstract

A multi-stream wireless relay is arranged to maintain independent data streams with multiple base stations and thereby provide a relay from those multiple base stations to mobile units having respective communication relationships with those multiple base stations. In an alternative approach, the data streams from the multiple base stations are superposed on each other, wherein harmful inter-cell interference is converted into useful information bearing signals, thereby enabling the scheduling of transmission resources from the multiple base stations for a single mobile unit via the relay.

Description

[0001] Cross References to Related Applications [0002] This application claims priority under 35 U.S.C.Sec 119(e) to U.S. Provisional Application 61 / 216,316, filed May 15, 2009, entitled "MULTI-STREAM WIRELESS RELAY," the subject matter of which is hereby incorporated by reference in its entirety . [0003] This application is related to U.S. Patent Application 12 / 455,215, entitled "SYSTEM AND METHOD FOR CELL EDGE PERFORMANCE MANAGEMENT IN WIRELESS SYSTEMS USING DISTRIBUTED SCHEDULING," filed May 30, 2009, assigned to the same assignee and registered at This is incorporated by reference. technical field [0004] The present invention generally relates to wireless repeaters. Background technique [0005] Wireless repeaters typically operate to relay (or retransmit) RF signals between a base station and user terminal equipment, such as mobile phones or other mobile stations, generally for the purpose of extending the range within which the user terminal equipment can be us...
