CENTRAL CONTROLLER AND METHODS FOR INTERFERENCE MITIGATION IN TDMA NETWORKS USING RANDOMLY ALLOCATED SERVICE PERIODS
First Claim
1. A central controller to coordinate operations of a wireless network, the central controller configured to allocate channel time allocations (CTAs) for peer-to-peer communications between pairs of communication stations of the wireless network,wherein the central controller is configured to randomize locations of the CTAs within superframes to mitigate co-channel interference from neighboring wireless networks.

1. A central controller to coordinate operations of a wireless network, the central controller configured to allocate channel time allocations (CTAs) for peer-to-peer communications between pairs of communication stations of the wireless network,
wherein the central controller is configured to randomize locations of the CTAs within superframes to mitigate co-channel interference from neighboring wireless networks.
-
11. A method for mitigating co-channel interference in a wireless network, the method comprising at least partially randomizing locations of channel time allocations (CTAs) within superframes by a central controller,
wherein pairs of communication stations of the wireless network communicate during the CTAs.
-
20. A wireless communication device to operate within a wireless personal area network (WPAN), the wireless communication device comprising:
-
a transceiver to receive an indication within a beacon period from a central controller of the WPAN, the indication to indicate randomization of channel time allocations (CTAs) within a next superframe; and a CTA schedule randomizer to generate a CTA schedule identifying locations of CTAs within the next superframe based on the indication provided in the beacon period, wherein the transceiver is configured to communicate with another wireless communication device during an assigned CTA in accordance with the CTA schedule. - View Dependent Claims (21, 22)

23. A central controller for a wireless personal area network (WPAN) comprising:
-
a transceiver to perform interference estimation to determine whether detected co-channel interference is static or dynamic, wherein when dynamic co-channel interference is detected, the transceiver is configured to inform communication stations of the WPAN that the locations of channel time allocations (CTAs) are to be randomized within superframes. - View Dependent Claims (24, 25)
