Assignee: MARVELL ASIA PTE LTD
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 10:
11. A first wireless communication device for communicating in a first wireless local area network (WLAN), comprising:
a wireless network interface having circuitry configured to:
determine a channel estimate of a communication channel between the first wireless communication device and a second wireless communication device in a second WLAN using measurements at the first wireless communication device of a first transmission between the second wireless communication device and a third wireless communication device in the second WLAN, and
generate a physical layer (PHY) protocol data unit (PPDU) for transmission to a fourth wireless communication device in the first WLAN, including:
determining, using the channel estimate of the communication channel between the first wireless communication device in the first WLAN and the second wireless communication device in the second WLAN, a precoder matrix to use for transmitting the PPDU in the first WLAN, and
generating the PPDU using the precoder matrix so that interference at the second wireless communication device in the second WLAN caused by transmission of the PPDU by the first wireless communication device in the first WLAN is reduced;

wherein the circuitry is further configured to:
determine that a first portion of a service coverage area of the first communication device is busy with a second transmission in the second WLAN to the second communication device,
determine that the PPDU is to be transmitted to the fourth communication device in the first WLAN concurrently with the second transmission in the second WLAN, and
control the wireless network interface to transmit, concurrently with the second transmission in the second WLAN, the PPDU to the fourth wireless communication device in the first WLAN as a directional third transmission.
