Abstract

Official abstract text for this publication.

Systems and methodologies are described that facilitate indicating a loss of channel quality on a component carrier of a plurality of component carriers. A UE can monitor configured component carriers to determine channel qualities associated therewith. The UE can transmit carrier quality information that includes the channel qualities of the plurality of component carriers. In addition, 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. In one aspect, the UE can incorporate additional information into a scheduling request. In addition, the UE can generate a CQI report that contains the carrier quality information. Further, the base station, when a loss of channel quality occurs, can retry transmission on different carriers. Moreover, the base station can employ information provided by the UE when selecting a component carrier for a transmission.

First claim

Opening claim text (preview).

What is claimed is: 1. A method of a wireless communications apparatus, comprising: identifying at least one component carrier, from a plurality of component carriers, experiencing a loss of channel quality; notifying a base station about the loss of channel quality on the at least one component carrier, wherein the notifying the base station comprises transmitting carrier quality information via Layer 3 signaling; and transmitting a scheduling request to the base station, whe…
