# lteSCIInfo

SCI message information

## Syntax

``info = lteSCIInfo(ue)``

## Description

example

````info = lteSCIInfo(ue)` returns an information structure indicating the payload sizes for SCI message formats. Release 12 defines a single SCI format 0, and Release 14 defines an additional format 1 for V2X sidelink. The output structure contains two fields with the message lengths for each format.To access the individual bit field sizes for the specified format, use `lteSCI`. ```

## Examples

collapse all

Get the information payload size of SCI message format 0 and format 1 for UE settings configuration with 10 MHz channel bandwidth.

A channel bandwidth of 10 MHz requires 50 resource blocks, `NSLRB = 50`.

```ue = struct('NSLRB',50); sci0length = lteSCIInfo(ue) ```
```sci0length = struct with fields: Format0: 43 Format1: 32 ```

Get the information payload size of SCI message format 0 for standard bandwidths.

```cbw = {'1.4MHz' '3MHz' '5MHz' '10MHz' '15MHz' '20MHz'}; disp('Bandwidth SCI Message Length (bits)')```
```Bandwidth SCI Message Length (bits) ```
```for ii = 1:size(cbw,2) ue = struct('NSLRB',cbw(1,ii)); sci0length = lteSCIInfo(ue); bw = cbw{1,ii}; fprintf('%6s %3d\n',bw, sci0length.Format0) end```
```1.4MHz 37 3MHz 39 5MHz 41 10MHz 43 15MHz 44 20MHz 45 ```

## Input Arguments

collapse all

User equipment settings, specified as a structure containing this parameter field:

Number of sidelink resource blocks, specified as an integer scalar from 6 to 110. (${N}_{\text{RB}}^{\text{SL}}$)

Example: `6`, which corresponds to a channel bandwidth of 1.4 MHz.

Data Types: `double`

## Output Arguments

collapse all

Payload size for the SCI message format, returned as a structure with the following parameter fields:

Format 0 payload size, returned as an integer indicating the SCI message length used for the scheduling of PSSCH.

Data Types: `double`

Format 1 payload size, returned as an integer indicating the SCI message length used for the scheduling of V2X PSSCH.

Data Types: `double`
