Abstract
An apparatus and system of uplink timing adjustment for frequency range 2 (FR2) communication with remote radio heads (RRHs) in a unidirectional high speed train (HST) deployment are described. A one-shot uplink timing adjustment is applied when a first value is greater than a second value. The first value is a difference between an end of a first transmission from a neighboring RRH and an end of reception of the first transmission at the UE less a difference between an end of a second transmission from a serving RRH and an end of reception of the second transmission at the UE. The second value is a predetermined gradual timing adjustment set by a 3GPP specification, the predetermined adjustment plus a timing error limit, the predetermined adjustment plus twice a downlink error, or a multiple of the predetermined adjustment. The one-shot uplink timing adjustment is twice the first value.
