Claim:
1. A method for scheduling two-hop based Intra-frame quiet periods (QPs), wherein QPs are part of frames transmitted in wireless regional area networks (WRANs) sharing a common channel, the method comprising: monitoring the common channel for a duration of at least a maximum self-coexistence window (SCW) cycle length; checking if at least one coexistence beacon protocol (CBP) packet including at least one intra-frame QP scheduled by neighbor WRANs is detected on the common channel; establishing an intra-frame QP schedule by setting intra-frame QP schedule fields in a modified superframe control header (SCH), wherein the intra-frame QP schedule is substantially aligned with any already scheduled QPs; and setting every 2-bits in an Intra-frame QP Cycle Frame Bitmap field to a value indicating that a frame corresponding to the field will be used exclusively by a WRAN.
