%% Create DL Subframe Resource Array Using Optional Antenna Plane Input
% Create an empty resource array that represents the downlink resource elements for 5 MHz bandwidth, one subframe, extended cyclic prefix, and four antenna ports.

cfg = struct('NDLRB',25,'CyclicPrefix','Extended');
p = 4;
griddl = lteDLResourceGrid(cfg,p);
size(griddl)
