Composite Include (LTE)

Composite Include contains a list of check boxes that determine which channels and signals are shown on traces and included in the EVM and EVM Pk data results on the Error Summary trace.

When a channel is selected, the channel is shown on the applicable traces (like IQ Meas, Error Vector Time, and RMS Error Vector Spectrum, etc.) in the color defined in the Frame Summary trace and is included in EVM Error vector magnitude (EVM): A quality metric in digital communication systems. See the EVM metric in the Error Summary Table topic in each demodulator for more information on how EVM is calculated for that modulation format..

Below is a list of channels. Click on the name of the channel to view more information about that channel.

Downlink
- C-RS - Cell-specific Reference Signal
- MBSFN-RS - Multicast/Broadcast Single Frequency Network Reference Signal
- PBCH - Physical Broadcast Channel
- PCFICH - Physical Control Format Indicator Channel
- PDCCH - Physical Downlink Control Channel
- PDSCH - Primary Downlink Shared Channel
- PHICH - Physical Hybrid ARQ Automatic Repeat Request 1) A distinct unit of data that is carried on an ARQ-enabled connection. Such a unit is assigned a sequence number, and is managed as a distinct entity by the ARQ state machines. Block size is a parameter negotiated during connection establishment. 2) automatic retransmission request - A signal used in digital communications systems used to signal the transmitting device to retransmit a block of data. Indicator Channel
- PMCH - Physical Multicast Channel
- P-RS - Positioning Reference Signal
- P-SS - Primary Synchronization Signal
- S-SS - Secondary Synchronization Signal
- UE-RS - UE User Equipment (e.g. cell phone)-specific Reference Signal (use Include check box in LTE Long Term Evolution Allocation Editor to determine whether UE-RS UE-specific Reference Signal is shown on traces, etc.)
Uplink
- PUSCH - Physical Uplink Shared Channel
- PUSCH DMRS - PUSCH Physical Uplink Shared Channel DeModulation Reference Signal
- PUCCH - Physical Uplink Control Channel
- PUCCH DMRS - PUCCH Physical Uplink Control Channel DeModulation Reference Signal
- SRS - Sounding Reference Signal
- PRACH - Physical Random Access Channel
  
  PRACH Physical Random Access Channel analysis is performed separately from PUSCH, PUCCH, and SRS Signaling Reference Signal.

Non-alloc

When selected, unused subcarriers are shown on applicable traces, such as IQ Meas and Error Vector Time.

Non-alloc signals consist of unused subcarriers in all shared and control channels. This includes unallocated user data subcarriers, the DC subcarrier In an orthogonal frequency division multiplexing (OFDM) or orthogonal frequency division multiple access (OFDMA) signal, the subcarrier whose frequency would be equal to the RF center frequency of the station. in downlink, and unused P-SS Primary Synchronization Signal and S-SS Secondary Synchronization Signal subcarriers. See the Non-alloc parameter topic for more information.

The Non-alloc row on the Frame Summary trace includes only unallocated shared channel (PDSCH Physical Downlink Shared Channel or PUSCH) subcarriers (those that could be allocated for users but are not). See the Frame Summary Non-alloc topic for more information.
