Methods and devices of error control with feedback resource allocation scheme
First Claim
1. Method of controlling transmission errors in a network comprising at least one transmitter, at least one receiver, a Radio Resource Management (RRM) unit for allocating transmission resource dedicated to said transmitter and/or receiver, and a FeedBacK (FBK) function comprising a transmitter FBK instance and a receiver FBK instance for managing transmission of feedback information which is transmitted by the receiver to the transmitter to indicate transmission errors, said method comprising the following steps:
- a) said transmitter FBK instance transmits Protocol Data Units (PDUs) to said receiver FBK instance;
b) said FBK function monitors transmission errors on the receiver FBK instance side and/or on the transmitter FBK instance side to determine a transmission quality level out of a set of given transmission quality levels;
c) said FBK function selects one feedback operational mode out of a predetermined list of feedback operational modes based on said determined transmission quality level, each one of said feedback operational modes defining a feedback resource allocation scheme for said transmitter FBK instance and said receiver FBK instance;
d) said receiver FBK instance transmits to said transmitter FBK instance feedback information via a resource allocated based on said selected feedback operational mode.

Abstract
There is disclosed a method and a device of controlling transmission errors in a network comprising at least one transmitter, at least one receiver and a Radio Resource Management (RRM) unit for allocating transmission resource dedicated to the transmitter and/or the receiver. A FeedBacK (FBK) function is introduced to manage transmission of feedback information which is transmitted by the receiver to the transmitter to indicate transmission errors. The FBK function comprises a transmitter FBK instance and a receiver FBK instance. At first, the transmitter FBK instance transmits Protocol Data Units (PDUs) to the receiver FBK instance. The FBK function monitors transmission errors on the receiver FBK instance side and/or on the transmitter FBK instance side to determine a transmission quality level out of a set of given transmission quality levels. The FBK function selects one feedback operational mode out of a predetermined list of feedback operational modes based on the determined transmission quality level, each one of feedback operational modes defining a feedback resource allocation scheme for the transmitter FBK instance and the receiver FBK instance. The receiver FBK instance transmits to the transmitter FBK instance feedback information via a resource allocated based on the selected feedback operational mode.
