Abstract

A method for clock synchronization of protocols in a network comprising a base station, BS, the BS comprising a BS scheduler, a user equipment, UE, and a master clock as an Over-the-Top, OTT, IP service on uplink and downlink channels, the method comprising the steps of: a) enabling, by the network, one or more IP communication flows between interfaces of the master clock and the UE for IP time synchronization packets or packets with similar symmetrical delay and low jitter requirements; b) receiving at the UE and the BS packets of these IP communication flows; c) disabling, at the BS and the UE, the use of Carrier-Aggregation, CA, Coordinated MultiPoint, CoMP, and Dual Connectivity, DC, for data of these IP communication flows; d) setting, at the BS and the UE, the target radio Block Error Rate, BLER, of the uplink and downlink channels to a value equal to or less than that of the IP communication flow's target packet loss rate; e) calculating, at the BS and the UE, the radio packet size so as to ensure that each packet is transmitted over a single radio transmission; f) signaling, from the network to the BS scheduler, a signal indicating to bypass radio scheduler queues; g) receiving a signal at the BS scheduler to bypass radio scheduler queues; h) signaling, from the BS to the UE, a signal indicating to utilize grant-free transmission on the uplink channel; and i) receiving, at the UE, a signal indicating to utilize grant-free transmission on the uplink channel.
