Patent ID: 8121106

Claim:
A method for managing uplink channel estimation in a base station, which base station is comprised in a radio access network using Frequency Division Duplex (FDD), the base station being associated with a first cell of a number of cells within the radio access network, the base station being adapted to connect at least one mobile terminal being situated in the first cell, to a network infrastructure, the method comprising the steps of: transmitting a redirected reference signal in an uplink band from the base station to the mobile terminal, said redirected reference signal being intended for uplink channel estimation; receiving a report from the mobile terminal that received the redirected reference signal, the report comprising the uplink channel quality estimated by the terminal by knowing the origin redirected reference signal transmitted from the base station, estimating the redirected reference signal, and comparing the known origin redirected reference signal with the received redirected reference signal; and performing uplink quality-based frequency-domain scheduling based on the uplink channel quality comprised in the report.
