A wireless communications system (1) has at least one base station, such as a personal base station (5), and a plurality of mobile stations (10) capable of wireless slotted communications with the at least one personal base station. A method includes a step of periodically deactivating, for a predetermined period of time, a base station transmitter (32) from transmitting a RF signal to at least one MS. A next step, executed during the predetermined period of time, operates a base station receiver (34) to perform a received signal strength (RSS) measurement. In a first embodiment of this invention the step of deactivating includes a preliminary step of reserving a reverse slot for use by the base station, thereby insuring that a mobile station will not transmit during the reserved slot. In this case the RSS measurement occurs during the reserved slot. In a second embodiment of this invention the step of deactivating includes an initial step of transmitting at least a synchronizing data pattern during the predetermined interval before disabling the transmitter, thereby enabling a mobile station to maintain synchronization with the base station even through the transmitter is switched off. |
