A method and system is disclosed for interlaced control channel. When a RAN in a wireless communication system operating at least according to IS-856 determines that a delay condition exists in the transmission of control packets to access terminals, it invokes interlacing of time slots bearing control-channel data. By so doing, control packets are transmitted in interlaced fashion, thereby reducing delay in transmission compared with sequential transmission of control packets. A delay condition could correspond to a measured delay exceeding a threshold delay, a predicted delay (e.g., based on queue occupancy) exceeding a threshold number, or the number of access terminals eligible to receive control messages during a particular time interval exceeding a different threshold number. The RAN may monitor transmission delay of control packets on a per-control-channel-cycle basis, and apply interlaced transmission of control packet only during those control-channel cycles for which a delay condition has been determined to exist. |
