1. A method for determining a metric of radio frequency channel quality for idle channels, the method comprising:
- at a receiver;
receiving a plurality of reference symbols transmitted by a transmitter for an idle channel state when user data and control channel data are not being transmitted by the transmitter;
using a first set of the reference symbols for channel estimation;
computing a metric of channel quality in the radio frequency channel using a second set of reference symbols different from the first set of reference symbols; and
alternatinqly, between subframes of the radio frequency channel, using the first and second sets of reference symbols for channel estimation and for computing the metric of channel quality.

Abstract
Methods, systems, and computer readable media for determining a metric of radio frequency channel quality for idle channels are disclosed. One method includes receiving a plurality of reference symbols transmitted by a transmitter for an idle channel state when user data and control channel data are not transmitted over the radio frequency channel. The method further includes computing a metric of channel quality using at least one of the reference symbols.

11. A system for determining a metric of radio frequency channel quality for an idle channel state, the system comprising:
-
a receiver including at least one processor for receiving a plurality of reference symbols transmitted by a transmitter for an idle channel state when user data and control channel data are not being transmitted by the transmitter; a channel quality metric calculation module operatively associated with the receiver for computing a metric of channel quality in the radio frequency channel using at least one of the reference symbols; and a channel estimation module for using a first set of the reference symbols for channel estimation, wherein the channel quality metric calculation module is configured to use a second set of reference symbols different from the first set for calculating the metric of channel quality, and wherein the channel estimation module and the channel quality metric calculation module are configured to alternatively, between subframes of the radio frequency channel, use the first and second sets of reference symbols for channel estimation and for calculating the metric of channel quality. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
