<p>User equipment for a wireless communication system, capable of selecting a sub-range of frequencies for uplink transmission from a plurality of sub-ranges of frequencies for uplink transmission, is described. The user equipment comprises: a) a wireless receiver capable of receiving a downlink signal that has been transmitted over a range of frequencies, comprising a plurality of sub-ranges of frequencies representative of a plurality of sub-ranges of frequencies for uplink transmission resources, the downlink signal having a known structural aspect as transmitted; b) a signal processor to determine a frequency domain response of the radio channel through which the downlink signal has passed by comparing the structural aspect of the received downlink signal with the known structural aspect of the reference signal as transmitted; and c) control logic to estimate radio channel quality for at least one of the sub-ranges of frequencies based on the frequency domain response of the radio channel and select at least one of the sub-ranges of frequencies for uplink transmission, based on radio channel quality.</p> |
