Abstract

Methods and apparatus for beamforming transmissions. A message is transmitted (1204) between the access node (112) and at least one terminal (130) over a radio link using beamforming transmission (911) based on said beamforming parameters. The message (1204) includes a copy of the data (411).

Description

technical field [0001] Various embodiments relate to a method comprising determining beamforming parameters and using beamforming transmission based on the beamforming parameters to transmit messages over a radio link between an access node and at least one terminal. The message includes a copy of the data encoded according to at least one redundancy version. Various embodiments relate to corresponding devices. Background technique [0002] Mobile communication via cellular networks is an integral part of modern life. One example of a cellular network is the 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) technology. [0003] LTE technology is a scheduling technology in which an access node (referred to as an evolved Node B (eNB) in the LTE framework) allocates time / frequency resources (resource blocks) for uplink (UL) and downlink (DL) communications. LTE technology employs a Transmission Time Interval (TTI) that provides a resource granularity of 1 m...
