Matlab Toolbox : 5G Library : PUCCH Format 0

In 5G communication systems, the PUCCH is used for transmitting uplink control information (UCI) from the user equipment (UE) to the base station. PUCCH Format 0 is one of the formats defined for PUCCH transmissions. It is used for periodic transmission of UCI.

Here's a technical breakdown of PUCCH Format 0 in MATLAB:

  1. Configuration:
    To use PUCCH Format 0 in MATLAB, you typically need to configure the physical layer parameters using the 5G Toolbox. This involves setting up the waveform parameters, channel configurations, and other system-specific settings.matlabCopy code% Example configuration
    carrierFreq = 3e9; % Carrier frequency in Hertz
    channelBW = 100e3; % Channel bandwidth in Hertz
    fs = 15e3; % Sampling rate in Hertz
    carrierConfig = nrCarrierConfig('CarrierFrequency', carrierFreq, 'ChannelBandwidth', channelBW, 'SamplingRate', fs);
  2. PUCCH Configuration:
    You need to configure the PUCCH specific parameters, such as the resource block (RB) indices, slot format, and other PUCCH-related settings.matlabCopy code% Example PUCCH configuration
    pucchConfig = nrPUCCHConfig;
    pucchConfig.ResourceIdx = 0; % Resource block index
    pucchConfig.SymbolIdx = 0; % Symbol index
  3. Generate PUCCH Waveform:
    Once configured, you can use the nrPUCCH function to generate the PUCCH waveform.matlabCopy code% Generate PUCCH waveform
    pucchSymbols = nrPUCCH(carrierConfig, pucchConfig);
  4. PUCCH Format 0 Specifics:
    PUCCH Format 0 is characterized by the transmission of periodic CSI (Channel State Information) and HARQ (Hybrid Automatic Repeat reQuest) feedback. The details of the payload, modulation, and coding for PUCCH Format 0 depend on the specific system and configuration.matlabCopy code% Example PUCCH Format 0 payload configuration
    pucchConfig.ResourceIdx = 1; % Example resource block index
    pucchConfig.SymbolIdx = 1; % Example symbol index
    pucchConfig.DeltaPUCCHShift = 0; % Example delta shift
  5. Visualization:
    You can visualize the generated PUCCH waveform using MATLAB plotting functions.matlabCopy code% Example visualization
    plot(real(pucchSymbols));
