Abstract:
1. A method of interpolating channel quality in a wireless communication system, said wireless communication system comprising a node B and a user equipment, said user equipment periodically reporting the channel quality to said node B, said method comprising the steps of: estimating, by said node B, the channel quality of the current period based on the channel quality of the preceding period reported by said user equipment; after estimating the channel quality of the current period reported by said user equipment, computing, by said node B, the difference between the estimated channel quality of the current period and the channel quality of the current period reported by said user equipment; performing weight processing on said difference; and obtaining, by said node B, a confidence parameter according to said difference, and interpolating the channel quality reported by said user equipment based on said confidence parameter.
