Scope of channel quality reporting region in a multi-carrier system
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 on the channel quality of the carrier, wherein the broadcast CQI is representative of all carriers included in the carrier set.
1. A wireless communications apparatus, comprising:
a memory that retains instructions related to creating a carrier set defined by a transmission scheme or a frequency band within which a subset of carriers was received at an access terminal, categorizing a carrier as belonging to the carrier set, utilizing the subset of carriers included in the carrier set as representative of all carriers included in the carrier set to measure a channel quality of the subset of carriers, and propagating a channel quality indicator (CQI) based on the channel quality of the subset of carriers; and
a processor, coupled to the memory, configured to execute the instructions retained in the memory.
2. The wireless communications apparatus of claim 1 , wherein the memory further retains instructions related to ascertaining whether transmission of the subset of carriers was effectuated utilizing a multiple input multiple output (MIMO) transmission scheme or a single input multiple output (SIMO) transmission scheme.
3. The wireless communications apparatus of claim 1 , wherein the memory further retains instructions related to ascertaining the frequency band within which the subset of carriers was broadcast by a serving base station.
4. The wireless communications apparatus of claim 1 , wherein the memory further retains instructions related to categorizing the subset of carriers based on the transmission scheme or the frequency band within which the subset of carriers was dispatched from a serving base station.
5. The wireless communications apparatus of claim 1 , wherein the memory further retains instructions related to determining the channel quality of the subset of carriers on receipt of at least one carrier included in the subset of carriers at the access terminal.
6. A method of communicating wirelessly, comprising:
creating a carrier set defined by a transmission scheme or a frequency band within which a subset of carriers was received at an access terminal;
categorizing a carrier as belonging to the carrier set;
utilizing the subset of carriers included in the carrier set as representative of all carriers included in the carrier set to measure a channel quality of the subset of carriers, and
propagating a channel quality indicator (CQI) based on the channel quality of the subset of carriers.
7. The method of claim 6 , further comprising ascertaining whether transmission of the subset of carriers was effectuated utilizing a multiple input multiple output (MIMO) transmission scheme or a single input multiple output (SIMO) transmission scheme.
8. The method of claim 6 , further comprising ascertaining the frequency band within which the subset of carriers was broadcast by a serving base station.
9. The method of claim 6 , further comprising categorizing the subset of carriers based on the transmission scheme or the frequency band within which the subset of carriers was dispatched from a serving base station.
10. The method of claim 6 , further comprising determining the channel quality of the subset of carriers on receipt of at least one carrier included in the subset of carriers-at the access terminal.

12. The apparatus of claim 11 , further comprising means for ascertaining whether transmission of the subset of carriers was effectuated utilizing a multiple input multiple output (MIMO) transmission scheme or a single input multiple output (SIMO) transmission scheme.
13. The apparatus of claim 11 , further comprising means for ascertaining the frequency band within which the subset of carriers was broadcast by a serving base station.
14. The apparatus of claim 11 , further comprising means for categorizing the subset of carriers based on the transmission scheme or the frequency band within which the subset of carriers was dispatched from a serving base station.
15. The apparatus of claim 11 , further comprising means for determining the channel quality of the subset of carriers on receipt of at least one carrier included in the subset of carriers at the access terminal.
16. A computer program product, comprising:
