lteSLResourceGrid

Sidelink subframe resource array

Syntax

grid = lteSLResourceGrid(ue)

grid = lteSLResourceGrid(ue,ntxants)

Description

grid = lteSLResourceGrid(ue) returns an empty resource grid matrix that represents the resource elements for one subframe, for the specified UE-specific setting structure.

For more information on the resource grid and the multidimensional array used to represent the resource elements for one subframe across all configured antenna ports, see Represent Resource Grids.

grid = lteSLResourceGrid(ue,ntxants) returns a 3-D resource grid array for the specified UE settings structure and number of antenna planes.

Examples

Create Empty Sidelink Resource Grid

Create an empty resource array representing the resource elements for 10 MHz bandwidth.

reGrid = lteSLResourceGrid(struct('NSLRB',50));

Input Arguments

ue — User equipment settings

structure

User equipment settings, specified as a structure containing these parameter fields:

NSLRB — Number of sidelink resource blocks

integer scalar from 6 to 110

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

CyclicPrefixSL — Cyclic prefix length

'Normal' (default) | 'Extended' | optional

Cyclic prefix length, specified as 'Normal' or 'Extended'.

Data Types: char | string

ntxants — Number of transmit antenna planes

positive integer

Number of transmit antenna planes, specified as a positive integer.

Data Types: double

Output Arguments

grid — Resource element grid

matrix | 3-D array

Resource element grid, returned as an N_SC-by-N_SYM-by-N_TX array.

• N_SC is the number of subcarriers, 12*ue.NSLRB.

• N_SYM is the number of SC-FDMA symbols in a subframe—14 for normal cyclic prefix or 12 for extended cyclic prefix.

• N_TX is the number of transmission antenna planes.
