Autonomous Timing Adjustment In A Communication Network

A method and apparatus for timing adjustment in a communication network. In a mobile network, one or more mobile stations (UEs) communication with a common base station (BS) for access to a core network. To align multiple uplink signals and reduce interference, a reference OTL is broadcast from the BS and received at the one or more UEs, the ROTL representing a real or theoretical maximum OTL (one-way trip latency). A universal time reference is then broadcast, often with other data, from the BS and is received by the one or more UEs. Each UE, if it is able, calculates its own OTL and uses that to calculate an δOTL representing an uplink transmission delay. In some cases, an δOTL′ may be calculated representing an uplink transmission delay that takes into account motion of the UE, if any. In some implementations, timing adjustments may be calculated by the BS and sent to individual UEs if necessary.
