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.

Abstract: A position location method includes receiving, over a messaging link, a request from an access point of a position location system to perform a ranging operation between a first asset tag and a second asset tag. The method also includes transmitting, by the first asset tag, a first ranging pilot signal on a ranging link to enable the ranging operation between the first asset tag and the second asset tag. The method further includes receiving, by the first asset tag, a second ranging pilot signal on the ranging link from the second asset tag.

Abstract: Methods, systems, and devices are described for managing wireless communications in a machine-to-machine (M2M) wireless Wide Area Network (WAN). A first paging message is transmitted in the M2M wireless WAN according to a first paging cycle. An occurrence of a first event is detected. A second paging message is transmitted, based at least in part on the occurrence of the first event. The second paging message is transmitted according to a second paging cycle. The second paging cycle being different from the first paging cycle.
