ENHANCED TRIGGER FRAME BASED DISCOVERY FOR A NEIGHBOR AWARENESS NETWORK

摘要

When a first node cannot hear a second node, the second node is “hidden” to the first node. In response to receiving a trigger frame, the two nodes may inadvertently transmit response frames at approximately the same time. The response frames may collide with each other, thereby causing delays in node discovery in a NAN. Provided herein are methods, apparatuses, and computer program products for reducing collisions in wireless communication. In some configurations, nodes may receive trigger frames that indicate a reduction in the rate that response frames are transmitted when traffic load conditions are high. In some configurations, nodes located in different coverage areas (e.g., a “hidden area” and a “non-hidden area”) may transmit response frames at different times. In some configurations, the nodes may refrain from transmitting their response frames upon hearing that another node having a higher serving preference rank is transmitting.

1. A method for wireless communication by a user equipment (UE), comprising:
transmitting a first trigger frame comprising a first criterion associated with a first area, wherein the first trigger frame is intended to trigger a first response frame from a first node in the first area; and transmitting a second trigger frame comprising a second criterion associated with a second area, wherein the second trigger frame is intended to trigger a second response frame from a second node in the second area.
