Abstract: A communication device, such as a smart phone, includes transmit/receive logic to cancel an interfering signal component. The interfering signal component may originate from a communication interface on the device itself. For example, transmissions from the communication interface may interfere with received signals at other communication interfaces on the device. Transmit/receive logic on others of the communication interfaces may use known characteristics of the interfering signal component to cancel the interfering signal component.

Abstract: Wi-Fi proximity considerations within single user, multiple user, multiple access, and/or MIMO wireless communications. Communications between a 1st wireless communication device (WDEV) (e.g., mobile) and a 2nd WDEV (e.g., terminal) are effectuated using wireless local area network (WLAN) based communications. Such communications may be adaptively performed based on at least one of proximity of the 1st WDEV to the 2nd WDEV and a predetermined movement of the 1st WDEV with respect to the 2nd WDEV or an object associated with the 2nd WDEV. For example, such a transaction may be effectuated between the 1st WDEV and the 2nd WDEV based on at least one (e.g., any one, any combination, any sub-combination, etc.) of received signal strength indicator (RSSI), angle of arrival (AoA), and time of flight (ToF) associated with at least one communication between the 1st WDEV and the 2nd WDEV.
