WIPO Patent Application WO/2020/124303

Kind Code:

A1

Abstract:

A method for data packet delay management in a communications network connecting a sender node over an eCPRI interface to a receive node. The method performed at the receiver node receiving data packets from the sender node comprises monitoring (102) a buffer level at a buffer receiving data from the sender node. When the buffer level reaches a threshold (104-Yes) the method further comprises transmitting (108) to the sender node over the eCPRI interface at least one message comprising information indicative of length of time of a Medium Access Control, MAC, flow control and transmitting (114) at least one MAC flow control frame to the sender node with a delay (110,112).
