Abstract
Official abstract text for this publication.
Aspect of the invention relate to a method for reporting channel quality information from a user equipment (UE) to a base station. In some embodiments, the method includes: determining a first channel quality value (CQ 1 ) for a first channel; reporting channel quality for the first channel, wherein the step of reporting channel quality for the first channel comprises transmitting from the UE to the base station a first channel quality indicator value (CQI 1 ) consisting of n bits; determining a second channel quality value (CQ 2 ) for a second channel; after determining CQ 2 , calculating a value of X, wherein X equals (i) DeltaCQ+an offset parameter value (P) or (ii) DeltaCQ−P, wherein P does not equal zero, and DeltaCQ equals (i) CQ 1 −CQ 2 , (ii) CQ 2 −CQ 1 , (iii) CQI 1 −CQI 2 or (iv) CQI 2 −CQI 1 , wherein CQ 12 is a function of CQ 2 ; and after calculating X, reporting channel quality for the second channel by transmitting from the UE to the base station an m bit value X′, wherein X′ is a function of X and m<n.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for reporting channel quality information from a first communication apparatus to a second communication apparatus, comprising: determining a first channel quality value (CQ 1 ), wherein CQ 1 corresponds to a quality measurement for a first channel; reporting channel quality for the first channel by transmitting from the first communication apparatus to the second communication apparatus a first channel quality indicator value (CQI 1 ) consisting…
