METHOD AND ARRANGEMENT FOR CONTROLLING TRANSMISSION OF DELAY SENSITIVE DATA IN A PACKET DATA COMMUNICATION NETWORK

摘要

This disclosure deals with an apparatus in a base station for controlling transmission of delay-sensitive data from a transmitter over a transmission link in a packet data communication network, which transmitter is capable of changing between a TTI bundling enabled mode and a TTI bundling disabled mode. The apparatus comprises: a receiver for receiving data from the transmitter over the transmission link; a decision unit for deciding that the transmitter should change TTI bundling mode; a silent mode detection unit for detecting that the transmitter is in the silent mode; and a triggering unit for triggering change of TTI bundling mode in response to deciding that the transmitter should change TTI bundling mode and in response to detecting that the transmitter is in the silent mode. The disclosure further relates to a corresponding method.

1. A method for controlling transmission of delay-sensitive data from a transmitter over a transmission link in a packet data communication network, where the transmitter is capable of changing between a transmission time internal (TTI1 bundling enabled mode and a TTI bundling disabled mode, the method comprising:
receiving data from the transmitter over the transmission link; deciding that the transmitter should change TTI bundling mode; detecting that the transmitter is in a silent mode, wherein the silent mode is a mode in which a service at the transmitter that generates delay-sensitive data is inactive; and triggering change of TTI bundling mode in response to deciding that the transmitter should change TTI bundling mode and in response to detecting that the transmitter is in the silent mode, wherein the change is not triggered until the transmitter is in the silent mode.
