Relay-Assisted Channel Condition Measurements For Connection Setup and Maintenance

摘要

A method is provided wherein communication channel conditions are communicated between a relay station and a mobile station to a base station, comprising: transmitting from the mobile station to the relay station information indicating the communication channel conditions between the relay station and the mobile station, such information including pilots with the uplink data message from the relay station to the base station, dedicated ranging codes from the relay station to the base station or contention-based initial ranging codes from the relay station to the base station; instructing, when either the dedicated ranging codes or contention-based initial ranging codes, the relay station by the base station of the dedicated ranging or contention-based initial ranging method used and having a relay station monitored the ranging method; processing the information received by the relay station in the relay station into a channel condition report; and transmitting from the relay station to the base station the channel condition report. A method is also for provided communication channel conditions between a relay station and a mobile station to a base station by communicating such channel conditions between the relay station and the mobile station to the base station using a down link (DL) preamble-based channel measurement wherein the relay station sends the preamble and each of the mobile station reports the measurement to base station.
