METHOD AND FIRST NODE FOR HANDLING A FEEDBACK PROCEDURE IN A RADIO COMMUNICATION

摘要

A method and a first node (700) for handling a feedback procedure requiring transmission of feedback messages indicating either an acknowledgement, ACK, or a non-acknowledgement, NACK, of correct reception of data transmitted on a forward link in a radio communication with a second node (702) in a radio network. The first node (700) obtains (300) a latency requirement of the radio communication corresponding to the time from transmission of the data until the data becomes outdated. The first node (700) further applies (304) a first transmission mode employing said feedback procedure when the latency requirement is above a latency threshold,and applies (306) a second transmission mode omitting said feed back procedure when the latency requirement is below the latency threshold.
