摘要： A client device includes a processor and an antenna. The client device obtains an announcement that specifies a winning client of a channel contention competition; identifies a group association of the client device using an identity of the winning client; transmits a preamble modulated by an entry of a preamble interference nullification matrix, the entry is based on the group association; and transmits, after transmitting the preamble, a data transmission. The preamble is transmitted at the same time as a second preamble is transmitted by a second client device.

摘要： A method for transmitting packets. The method includes making a first determination, using a first relevant sample set for a first client device, that the first client device does not need to be sounded and making a second determination, using a second relevant sample set for the second client device, that a second client device needs to be sounded. The method further includes, based on the first and second determination, performing a sounding operation for the second client device to obtain channel state information for the second client device and after performing the sounding operation for the second client device: wirelessly transmitting at least one packet to the first client device using historical channel state information for the first client device, and wirelessly transmitting at least one packet to the second client device using the channel state information.

摘要： A method includes generating, by a wireless device, a sounding packet. The method includes sending, by the wireless device, copies of the sounding packet using a beam former and an antenna array to a second wireless device. Each copy of the copies of the sounding packet is sent using different beam weights. The method includes, in response to sending the copies of the sounding packet, obtaining, by the wireless device, a first correction beam weight and a second correction beam weight from the second wireless device and sending, by the wireless device, data to the second wireless device using the first correction beam weight and the second correction beam weight.

摘要： A method of wireless local area network communication between a client and an access point includes sending, by the client, a client-originated message to the access point over a bidirectional upload channel; receiving, by the client, a client-acknowledgement message from the access point over the bidirectional upload channel; receiving, by the client, an access point-originated message from the access point over a bidirectional download channel that was generated in response to the client-originated message; and sending, by the client, an access point-acknowledgement message to the access point over the bidirectional download channel. The bidirectional download channel is separate from the bidirectional upload channel.
