<p>The invention relates to a wireless local loop system comprising base stations and an access network node which connects the cordless terminal equipments (T) to the exchange of the fixed network. The air interface between the cordless terminal equipment and the base station (2, 3) is mainly in accordance with the GSM mobile system. In addition to the base station, the terminal equipment (T) also measures the field strength and quality of the radio channel. There are at least two measurement periods during a multiframe of a traffic channel (TCH), and the terminal equipment transmits the measurement results of the first measurement period in a single burst in a time slot of a slow associated control channel (SACCH) and the measurement results of the second measurement period in a single burst in a time slot of an IDLE frame. There are at least two transmissions of control information during the multiframe, and the base station transmits the first control information in a single burst in a time slot of the SACCH and the second control information in a single burst in a time slot of the IDLE frame. In this manner the measurement period can be made shorter than the frequency of the Rayleigh fading.</p> |
