ABSTRACT:
A network element is configured to implement scheduled high-power Point-To-Point (PTP) and low-power Point-To-MultiPoint (TMP) transmissions. The high-power PTP and low-power PTMP transmissions may be scheduled as bursts on an 802.16 network to occur in both the downlink subframe and uplink subframe on a given frequency channel in the wireless network. The use of an air interface for both types of communications allows the PTP and PTMP communications to be scheduled relative to each other in a unified manner to increase quality of service and minimize interference between the backhaul PTP and access PTMP networks, even though the PTP and PTMP communications take place on the same channel using the same underlying wireless technology. Buffers may be used to store data received in a PTP downlink burst prior to transmission in a PTMP downlink burst, and may be used to store data received in an uplink PTMP burst prior to transmission in an uplink PTP burst.
