METHODS AND APPARATUS FOR DISTRIBUTING CHANNEL TIMING AMONG SUBSCRIBER UNITS IN TDMA DIRECT MODE Russian patent published in 2015 - IPC H04W56/00 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to wireless communication. The method includes: receiving, from a second one of the subscriber units operating in the TDMA direct mode, a first message; determining first channel timing from the received message; determining whether the received first channel timing is correct, wherein the determining is based at least on comparing a version of the first subscriber unit with a version of the second subscriber unit; when the received first channel timing is correct, starting a random delay; upon expiration of the random delay, transmitting a first forced distribution message to distribute the first channel timing to at least a third one of the subscriber units operating in TDMA direct mode and having a higher version than the versions of the first and the second subscriber units.

EFFECT: invention is intended to distribute channel timing among subscriber units in time division multiple access (TDMA) direct mode.
