Definitions

  • An electronic device a method, a computer program product, and a single-chip radio
  • the present disclosure relates to an electronic device, a method, a computer program product, and a single-chip radio. More specifically, the disclosure relates to an electronic device, a method, a computer program product, and a single-chip radio as defined in the introductory parts of the independent claims.
  • Wireless communication is expanding to new radio spectrum parts in order to meet the requirements for higher data rates.
  • 5G fifth generation new radio
  • NR new radio
  • NR introduces wireless communication on millimeter wavelength (mmW) radio frequencies (e.g., frequency bands above 10 GHz, such as the 28 GHz frequency band or the 39 GHz frequency band). Due to the fact that mmW radio frequencies typically entail higher path loss than lower frequency signaling, cells of a mmW cellular wireless communication system will typically cover smaller areas than those of a lower frequency communication system. Therefore, communication devices supporting 5G NR in the mmW frequency range will typically support also wireless communication using lower frequencies (e.g., below 6 GHz) for coverage.
  • mmW millimeter wavelength
  • mmW transmission is that the short wavelength enables use of small antennas, which in turn makes it possible to have massive-MIMO transceiver arrangements comprised in small (e.g., handheld) wireless communication devices. For example, it may be possible to fit antenna panels with, e.g., 4x2 antennas in a module having a size of approximately 25x10 mm. This advantage enables application of beamforming for mmW, which may significantly increase the cellular capacity and/or coverage.
  • Transceiver architectures for Massive MIMO and beamforming are generally realized in two different ways - analog and digital beamforming. However, in some applications hybrid beamforming is employed, which may be understood as a combination of the two.
  • analog beamforming is performed at the Radio Frequency (RF) chip through a bank of phase shifters, one per antenna element, and an analog power combiner (receiver) and power splitter (transmitter).
  • the beam direction of the combined radio signal of the antenna array can by controlled by tuning the phase shifters. Different, or the same, directions may be applied for transmission and reception.
  • This architecture only requires one pair of analog-to-digital converters (ADC) and digital-to-analog converters (DAC) at the receiver and transmitter, respectively, reducing the complexity.
  • ADC analog-to-digital converters
  • DAC digital-to-analog converters
  • the antenna elements are typically clustered and implemented in an antenna panel.
  • a disadvantage with analog beamforming is that the antenna array can only apply a single (transmit and/or receive) beam at the same time. This leads to that simultaneous multiuser scenarios using the same antenna array are not possible. Furthermore, abrupt changes of channel conditions (e.g., due to blocking of antennas, rotation of the transceiver, etc.) are hard to track with a single beam limitation. Thus, there is a high risk of signal outage in connection to abrupt changes of channel conditions. Digital beamforming may provide increased flexibility compared to analog beamforming. In digital beamforming implementations, the beamforming is performed in the digital baseband (BB) chip.
  • BB digital baseband
  • Each transceiver chain has a pair of ADCs at the receiver and DACs at the transmitter enabling the transceiver to simultaneously direct beams in, theoretically, an infinite number of directions at a given time. Thereby, several beams can be tracked simultaneously, and it may be possible to follow fast changes of channel conditions, thereby improving receiver and/or transmitter performance.
  • digital beamforming provides advantages from a flexibility of antenna placement point of view, especially in handheld devices, where the antennas generally need to be distributed over the device in order to combat blocking of the mmW radio signals caused by e.g., hand-placement while handling the device.
  • some digital beamforming architectures comprise multiple (N) analog mmW RF chips or modules that are connected to a baseband chip via an analog interface.
  • Each analog mmW RF chip comprises one or more antennas, front-end receiver (TRX) and front-end transmitter (TRX), as well as an analog baseband receiver and transmitter filter.
  • the output analog baseband signal (from each mmW RF chip) is input to each of the N inputs of the baseband chip.
  • the baseband chip is accordingly provided with N ADCs/DACs and suitable pre-processing and coding/decoding circuitry.
  • N ADCs/DACs DACs and suitable pre-processing and coding/decoding circuitry.
  • digital beamforming architectures utilize a digital interface between the N number of mmW RF chips and the baseband chip.
  • some of the circuitry e.g., ADCs, DACs, and digital filters
  • the output from each mmW RF chip is a digital signal over the digital interface, which is provided to the inputs of the baseband chip, which comprises the pre-processing circuitry and the coding/decoding circuitry.
  • Going to a digital interface, and incorporating ADC/DACS in the RF chips it may also be possible to have serial connection between the TRX chips as shown in e.g, WO 2020/052880 Al.
  • the antenna panels 10a, 10b, 10c are connect to a mmW radio chip 15, down-converting the mmW radio signal to a sub 6 GHz radio signal. Then a switch 16 selects which of the antenna panels 10a, 10b, 10c is used (i.e., only a single antenna panel is enabled at the same time). The signal from the mmW chip is then sent to the sub 6GHz RF chip 17 and then down converted to a baseband signal and sent to a BB processing unit 19.
  • the current smartphone implementation with antenna panels has the disadvantages that it is bulky, and that in case the antenna panel directed towards the network node is blocked by a hand another antenna panel, with a much worse radio channel/signal quality towards the NW node needs to be used implying significant signal loss and hence lower data rates or even a dropped radio link.
  • US 2020/0083948 Al discloses an electronic device including an antenna module.
  • the antenna module of US 2020/0083948 Al is rather spacious and the space of the antenna module and/or the electronic device (or components thereof) may need to be reduced.
  • clustered antennas in an antenna panel such as the ones mentioned in US 2020/0083948 Al (wherein all antenna elements are positioned on a single printed circuit board) may be disadvantageous since a hand can block all antennas at the same time.
  • Distributed architecture reduces the risk of all antennas being blocked.
