Abstract
Systems and methodologies are described that effectuate or facilitate multichannel feedback in multichannel wireless communication environments. In accordance with various aspects set forth herein, systems and/or methods are provided that construct a carrier set, classifies a carrier as belonging to the carrier set, utilizes the carrier as representative of all carriers included in the carrier set to measure a channel quality of the carrier, and transmits a CQI based at least in part of the channel quality of the carrier, wherein the broadcast CQI is representative of all carriers included in the carrier set.
Claims29
A method that effectuates multichannel feedback in a multichannel wireless communication environment, comprising:
- defining, by a mobile device, a carrier set of carriers having first parameters from a band with a plurality of carriers including carriers having the first parameters and carriers having second parameters;
- grouping, by the mobile device, a carrier into the carrier set based on the carrier having the first parameter;
- measuring, by the mobile device, a channel quality of the carrier without measuring channel quality of all carriers in the carrier set;
- and
- transmitting, from the mobile device, a channel quality indicator (CQI) for the carrier set, the CQI based at least in part on the channel quality of the carrier.
A wireless communications apparatus that effectuates or facilitates multichannel feedback in a multichannel wireless communication environment, comprising:
- means for defining a carrier set of carriers having first parameters from a band with a plurality of carriers including carriers having the first parameters and carriers having second parameters;
- means for grouping a carrier into the carrier set based on the carrier having the first parameter;
- means for measuring a channel quality of the carrier without measuring channel quality of all carriers in the carrier set;
- and
- means for transmitting a channel quality indicator (CQI) for the carrier set, the CQI based at least in part on the channel quality of the carrier.
A non-transitory machine readable medium, comprising:
- code for defining, by a mobile device, a carrier set of carriers having first parameters from a band with a plurality of carriers including carriers having the first parameters and carriers having second parameters;
- code for grouping, by the mobile device, a carrier into the carrier set based on the carrier having the first parameter;
- code for measuring, by the mobile device, a channel quality of the carrier without measuring channel quality of all carriers in the carrier set;
- and
- code for transmitting, from the mobile device, a channel quality indicator (CQI) for the carrier set, the CQI based on the channel quality of the carrier.
A wireless communications apparatus, comprising:
- a processor configured to:
- define a carrier set of carriers having first parameters from a band with a plurality of carriers including carriers having the first parameters and carriers having second parameters;
- group a carrier into the carrier set based on the carrier having the first parameter;
- measure a channel quality of the carrier without measuring channel quality of all carriers in the carrier set;
- and
- transmit a channel quality indicator (CQI) for the carrier set, the CQI based at least in part on the channel quality of the carrier;
- and
- a memory operably connected to said processor.
