MIDPACKET DETECTION SCHEMES FOR CLEAR CHANNEL ASSESSMENT (CCA)

摘要

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.

1. An apparatus for wireless communications, comprising:
a receiver configured to receive signals on a primary channel; and a processing system configured to:
detect, based on the received signals, occurrence or non-occurrence of a first on-going packet transmission on the primary channel; andgenerate at least one of a busy signal or an idle signal based on the detection.
