ABSTRACT:
A method and device for measuring signal strengths by mobile stations in a wireless communication system are provided with minimal complexity. More particularly, while transmitting and receiving on a channel, scheduled signal strength measurements may be required. For instance, the received signal strength of broadcast information slots at the beginning of a superframe may be measured at predetermined times for several carriers. Also, the required signal strength measurements may be scheduled by a mobile station at times which minimize interference with the tasks of transmitting and receiving messages. Scheduled signal strength measurements may be delayed when the mobile is transmitting and receiving on a channel, and then more frequent signal strength measurements may be made when there is no communication. In other words, the signal strength measurements do not have to occur uniformly in time, but may be more frequently performed if they have been delayed.
