Uplink Channels

Uplink physical signals, physical channels, transport channels, control information, and SC-FDMA modulation

Use LTE Toolbox™ mid-level uplink channel processing functions to:

  • Create physical signals and physical channels for transmission and reception.

  • Create, encode, and decode transport channels.

  • Create, manipulate, encode, and decode control information messages.

  • Perform SC-FDMA modulation and demodulation.

For function mapping within uplink grid, see Uplink Physical Channels and Signals Grid.

  • Physical Signals
    Demodulation reference signals for PUSCH and PUCCH formats 1, 2, and 3; sounding reference signals
  • Physical Channels
    PUSCH and PUCCH formats 1, 2, and 3 modulation, coding, and indices; PRACH generation, detection
  • Transport Channels
    UL-SCH coding, interleaving, information
  • Control Information
    UCI, CQI, and RI coding; PMI information and selection; RI and CQI selection; codebook for CSI reporting
  • SC-FDMA Modulation
    Single-carrier frequency division multiple-access modulator, demodulator, dimension information

Featured Examples

Uplink Waveform Modeling Using SRS and PUCCH

Uplink Waveform Modeling Using SRS and PUCCH

Demonstrates how to configure User Equipment (UE) and cell-specific Sounding Reference Signals (SRS) transmission. Physical Uplink Control Channel (PUCCH) is also configured for transmission.

Mixed PUCCH Format Transmission and Reception

Mixed PUCCH Format Transmission and Reception

The transmission and reception of Physical Uplink Control Channel (PUCCH) Formats 1 and 2, including the case where the same physical resource is shared between transmissions of Format 1 and Format 2 simultaneously from two different User Equipments (UEs) using the LTE Toolbox™.

LTE-M Uplink Waveform Generation

LTE-M Uplink Waveform Generation

Create an uplink LTE-M transmission consisting of the Physical Uplink Shared Channel (PUSCH) and associated demodulation reference signals (DM-RS) including repetitions and frequency hopping. When compared to pre-release 13 devices, Cat-M devices offer lower cost and complexity, enhanced coverage by the introduction of repetitions and an extended DRX for further power saving.
