Using synchronization frames for mesh networking with piconets
Certain aspects provide a technique for managing transmissions in a wireless network. The technique generally provides for an access terminal to transmit synchronization packets containing timing information regarding an existing piconet. The synchronization packets may contain an indication of resources of the piconet allocated to the access terminal by an access point.
1. A method of wireless communication performed by an apparatus, comprising:
performing ranging operations for a destination node that is to receive wirelessly distributed video to determine proximity between a wireless video source and the destination node; and
adjusting at least one of a bandwidth or resolution of the wirelessly distributed video based on the determined proximity,
wherein the ranging operations include the steps of:
receiving, from the destination node, a synchronization packet containing a time stamp indicating a transmission time of the synchronization packet; and
calculating a result based on a difference between a time when the synchronization packet was received and a time indicated by the time stamp.
2. The method of claim 1 , wherein the adjusting comprises:
increasing the resolution of the wirelessly distributed video if the results of the ranging operations indicate the wireless video source and the destination node are in relatively close proximity to each other.
