Abstract: Systems, methods, and apparatus are disclosed for increasing reuse in wireless communications. In one aspect, a method of wireless communication is provided, transmitting a message to a first station indicating an identified transmission opportunity for the first station to communicate with a second station. The method further comprises transmitting a first wireless communication signal to at least a third station utilizing beamformed wireless communication such that the first wireless communication signal to the third station has a received signal level below a threshold at one or both of the first and second stations. The identified transmission opportunity is based on whether a transmission of a second wireless communication signal between the first and the second stations occurs over a period of time that is at least partially concurrent with the utilized beamformed communication.

Abstract: In a conditional channel measurement operation, an apparatus may determine how to invoke a channel measurement operation based on whether one or more measurement operation conditions are met. A channel measurement operation may involve measuring conditions on a channel, reporting results of a channel measurement, or some other operation related to measurement of a channel. A measurement operation condition may relate to resource availability, a measurement timing criterion, or some other condition used to control how a channel measurement-related operation is conducted. In some aspects, conditional channel measurement operations involve determining whether, when, and the manner in which channel conditions are measured and/or reported. For example, an apparatus may conduct a measurement and/or report the results of a measurement at a time or in a manner that mitigates impact on channel traffic and/or at least one resource.
