Techniques to provide a channel quality indicator

An apparatus comprising:

• a computer configured to:
• selectively determine a channel quality indicator over a group of one or more sub-channels in response to receipt of a request to determine the channel quality indicator for the group, wherein the request to determine the channel quality indicator comprises identification of a codebook index and a parent node, the codebook index and parent node together identify assignable basic resource blocks, the codebook index identifies an order of base resource blocks among sub-channels of the parent node, and the order is among multiple potential orders;
• and
• request to transmit the determined channel quality indicator, wherein bandwidth allocable to transmission of channel quality indicator is adjustable based in part on a number of sub-channels in the group.

A system comprising:

• a base station comprising:
• logic to request determination of a channel quality indicator over a group of at least one sub-channels, wherein to request determination of the channel quality indicator comprises identification of a codebook index and a parent node, the codebook index and parent node together identify assignable basic resource blocks, the codebook index identifies an order of base resource blocks among sub-channels of the parent node, and the order is among multiple potential orders, and
• at least one antenna capable to receive and transmit signals;
• and
• at least one subscriber station comprising:
• logic to determine the channel quality indicator over the group, and
• logic to transmit the determined channel quality indicator to the base station, wherein a bandwidth allocable to transmission of channel quality indicator is adjustable based in part on a size of the group.
