lteNPUSCHIndices
Description
[
generates ind
,info
] = lteNPUSCHIndices(ue
,chs
)ind
, a column vector of narrowband physical uplink shared
channel (NPUSCH) resource element (RE) indices, and info
, information
related to the indices. The function generates indices for mapping NPUSCH symbols to
physical resources, as specified in Section 10.1.3.6 of [1], for user equipment
(UE) settings ue
and channel transmission configuration
chs
.
Examples
Generate NPUSCH RE Indices
Configure UE-specific settings.
ue = struct('NBULSubcarrierSpacing','15kHz');
Specify a channel transmission configuration.
chs = struct('NPUSCHFormat','Data','NBULSubcarrierSet',[0:11],'NRU',1, ... 'NULSlots',2,'Modulation','BPSK');
Generate the NPUSCH RE indices for the specified settings. Display the corresponding information.
[ind,info] = lteNPUSCHIndices(ue,chs); disp(info)
Gd: 144 G: 144
Generate Zero-Based NPUSCH RE Indices
Configure UE-specific settings.
ue = struct('NBULSubcarrierSpacing','15kHz');
Specify a channel transmission configuration.
chs = struct('NPUSCHFormat','Data','NBULSubcarrierSet',0:11, ... 'NRU',1,'NULSlots',2,'Modulation','BPSK');
Generate the NPUSCH RE indices, specifying zero-based formatting.
[ind,info] = lteNPUSCHIndices(ue,chs,'0based');
