Syntax

info = lteSCIInfo(ue)

Description

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.

Open Live Script

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
Open Live Script

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

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.

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

Data Types: double

Output Arguments
