Patent ID: 7127262

Claim:
A method for determining frequency channel quality in a mobile radio system, comprising: in a predetermined temporal sequence of transmit time intervals and receive time intervals, transmitting respective data blocks on respective frequency channels during respective ones of the transmit time intervals and receiving respective data blocks on respective frequency channels during respective ones of the receive time intervals; and for a first of the time intervals which has associated therewith a corresponding first frequency channel, making a received signal strength measurement on the first frequency channel during a period of time between the first time interval and a second of the time intervals that is adjacent the first time interval in the temporal sequence and not during the first time interval and the second of the time intervals, wherein the second time interval precedes the first time interval in the temporal sequence; and locking onto the first frequency channel during a frequency locking portion of the period of time between the first and second time intervals, wherein the making step includes making the received signal strength measurement during the frequency locking portion and after locking onto the first frequency channel.
