The frequency at which the lowest power is received is chosen as uplink frequency. When choosing the downlink frequency, a tuning signal is transmitted at all frequencies or at some frequencies of the transmission band. Mobiles located in areas of other cells and operating at the same frequency experience the effect of the tuning signal as an interference. The base station is tuned to use that downlink frequency at which the interference caused by itself to other traffic is sufficiently low.Field of SearchChannel allocationOptimum frequency selection Ranking (e.g., based on signal strength, etc.) Channel allocation Plural receivers tuned to common frequency Control channel monitoring (i.e., paging or access channel signaling) for system access Usage measurement Frequency reuse scheme Channel selection or allocation Including cell planning or layout Automatic frequency control Frequency hopping Multiple access (e.g., TDMA) | |
