摘要： In a method for reducing interference in wireless communications, a beamforming matrix is determined at a first communication device based on an estimate of a multiple input, multiple output (MIMO) communication channel between the first communication device and a second communication device. Both the first communication device and the second communication device belong to a first wireless network. Alternatively, the beamforming matrix may be generated based on the estimate of the MIMO communication channel and received at the first communication device. The beamforming matrix is used at the first communication device for the purpose of reducing interference to a second wireless network, where the interference is caused by the first communication device transmitting to the second communication device via the MIMO communication channel.

摘要： In a method for reducing interference in a first wireless communication network and a second wireless communication network, a first access point (AP) device of the first wireless communication network coordinates with a second AP device of the second wireless communication network with respect to utilizing transmit beamforming at the first AP device and transmit beamforming at the second AP device for the purpose of reducing interference in the first wireless communication network and the second wireless communication network. Based on coordinating with the second AP device, the first AP device uses a beamforming matrix to transmit, via a multiple input, multiple output (MIMO) communication channel, to one or more first stations in the first wireless communication network for mitigating interference between the first wireless communication network and the second wireless communication network.

摘要： A TDD/TDMA wireless superframe includes a slot having a plurality of OFDM symbols. A guard time interval is arranged after the slot containing the OFDM symbols. There are a plurality of packets arranged subsequent to the guard time interval. A majority of the plurality packets comprise payload frames that are dynamically assigned in concatenation so as to provide access to/from one or more legacy devices operating in a LAN environment under a different protocol. The TDD/TDMA protocol is compatible with existing legacy devices under CSMA/CA. When there is at least one legacy device and one non-legacy device receiving communication, the legacy device is provided communication by enabling the Dynamic Contention packet service, with both the legacy device and non-legacy device receiving communications in the same frequency band.
