FAILURE INDICATION FOR ONE OR MORE CARRIERS IN MULTI-CARRIER COMMUNICATION ENVIRONMENT

摘要

PROBLEM TO BE SOLVED: To facilitate indicating a loss of channel quality on a component carrier of a plurality of component carriers.;SOLUTION: A UE can monitor configured component carriers to determine channel qualities associated therewith, and transmit carrier quality information that includes the channel qualities of the plurality of component carriers. The UE can identify a component carrier experiencing a loss of channel quality and notify a base station of the component carrier with poor channel conditions. The UE can incorporate additional information into a scheduling request. The UE can generate a CQI report that contains the carrier quality information. The base station, when a loss of channel quality occurs, can retry transmission on different carriers. The base station can employ information provided by the UE when selecting a component carrier for a transmission.;COPYRIGHT: (C)2014,JPO&INPIT
