Abstract: Certain aspects of the present disclosure generally relate to techniques and apparatus for determining a primary channel for wireless communication. According to certain aspects, a method is provided for wireless communications by an apparatus. The method generally includes obtaining an information element (IE) with one or more parameters and computing a primary channel location to be used for the wireless communication, as a function of the one or more parameters, wherein the function is independent of a geographical area in which the apparatus is located.

Abstract: Certain aspects of the present disclosure provide methods and apparatus for detecting ongoing transmissions and assessing channel state, based on midpacket detection. One example method generally includes receiving signals on a primary channel; detecting, based on the received signals, occurrence or non-occurrence of a first ongoing packet transmission on a primary channel; and generating at least one of a busy signal or an idle signal based on the detection. In this manner, collisions may be avoided.
