A mobile station receives forward link signals and transmits reverse link signals for a communication session conducted via a wireless network. A controller maintains a reverse-active set that defines which sectors of the wireless network are used to receive the reverse link signals. When the mobile station transmits a request signal requesting the communication session, the controller may create the reverse-active set to include the sector that received the request signal with the highest signal strength. During the communication session, the signal strengths of the reverse link signals may be monitored in each of a plurality of sectors to obtain reverse-link signal strengths. The controller may maintain the reverse-active set based on the reverse-link signal strengths, adding sectors that report reverse-link signal strengths greater than an add threshold and dropping sectors that report reverse-link signal strengths less than a drop threshold.
