Abstract: Millimetre-wave (mmWave) communications have emerged as a promising solution to meet the ever-increasing data demand in the next-generation wireless networks thanks to the rich amount of available spectrum resources. However, beamforming, the enabler of mmWave communications, requires the accurate angle of departures (AoDs) at the transmitter and angle of arrivals (AoAs) at the receiver, which is usually time-consuming to obtain due to the highly directional transmission and reception in mmWave communications. This becomes more challenging in time-varying scenarios since the time-demanding beam training process has to be invoked frequently to update the stale AoAs and AoDs, which incurs significant traffic overhead.
As potential solutions to address the aforementioned issue, novel beam tracking techniques for time-varying mmWave multiple-input single-output (MISO) system will be introduced in this talk, and several efficient training beam sequence designs that are suitable for different AoD tracking scenarios will be explained as well.
