Publication number: 20140056237Abstract: In an example of the teachings disclosed herein, there are multiple signaling options available for triggering a bundled transmission by a wireless device, and a known association between the different signaling options and different TTI bundling sizes. A network node thus indicates to the wireless device which TTI bundling size is desired, based on choosing which signaling option it uses to trigger the bundled transmission. Such signaling allows for the use of variable TTI bundle sizes, i.e., dynamic control of the TTI bundle size used by the wireless device for transmission and yet does not impose signaling overhead or necessarily require new signaling messages or types. Higher layer signaling may be used to activate TTI bundling with implicit signaling then used to dynamically control the actual TTI bundle size used.Type: ApplicationFiled: December 17, 2012Publication date: February 27, 2014Applicant: TELEFONAKTIEBOLAGET L M ERICSSON (PUBL)Inventors: Erik Eriksson, Xinghua Song
