Patent ID: 8824381

Claim:
A method, comprising: transmitting feedback information on a feedback information channel dedicated for the feedback information at a first power spectral density level; determining that an uplink resource request is to be transmitted on the feedback information channel in response to determining that uplink resources are not available on a resource request channel; transmitting the uplink resource request on the feedback information channel, wherein the uplink resource request is transmitted on the feedback information channel at a second power spectral density level higher than the first power spectral density level, wherein the second power spectral density level is selected in response to determining that the uplink resource request is to be transmitted on the feedback information channel and to lower an error rate of the feedback information channel during transmission of the uplink resource request; and reducing the power spectral density of the feedback information channel from the second power spectral density level subsequent to transmission of the uplink resource request and prior to transmitting feedback information on the feedback information channel.
