Abstract:
1. A method at network node in a wireless communication network, for dynamically controlling a Transmission Time Interval (TTI) bundle size used by a wireless device for a bundled transmission by the wireless device, the method comprising: determining a desired TTI bundle size to be used by the wireless device for the bundled transmission; selecting a signaling option to be used for triggering the bundled transmission by the wireless device, based on the desired TTI bundle size and a defined mapping between different signaling options among a number of signaling options and different TTI bundle sizes in a defined set of TTI bundle sizes, wherein the defined mapping is known at the network node and at the wireless device, and indicating the desired TTI bundle size to the wireless device by triggering the bundled transmission using the selected signaling option.
