A medium access control (MAC) scheduler is disclosed for scheduling uplink (UL) traffic by a subscriber station having multiple active service connections. The scheduler may include two types of queue sets, a first type of queue for each unsolicited grant service (UGS) connection and a second type of queue for each and all other non-UGS connections. Upon receipt of an overall bandwidth grant from a base station, data in the first type of queues may be sent first and then data in the second type of queues is sent if there is sufficient remaining burst space in the granted UL frame. The second type of queues may be assigned weight value, and thus scheduled, depending on the type of connection. When serving the second type of queues, initial burst space allocation may be reserved for bandwidth requests to the base station. Additional embodiments and variations are also disclosed.
