Glossary Item Box

Gets the per-symbol selection bitmap within a single LTE slot. The bitmap is always 7 bits (MSB = symbol 0, LSB = symbol 6). A bit value of 1 means the rate match pattern is active during that symbol.

Syntax

Visual Basic (Declaration) 
Public MustOverride Function GetSymbolBitmap() As BitArray
C# 
public abstract BitArray GetSymbolBitmap()
C++/CLI 
public:
abstract BitArray^ GetSymbolBitmap();

Return Value

The current per-symbol selection bitmap.

Remarks

Valid bit-index range depends on the cyclic-prefix length of the analyzed signal:
  • Normal cyclic prefix (or auto-detected normal CP): bits 0..6 are valid (7 OFDM symbols per slot).
  • Extended cyclic prefix (or auto-detected extended CP): bits 0..5 are valid (6 OFDM symbols per slot); bit 6 has no effect.
This keeps the configuration stable when the cyclic-prefix length is in auto mode — the user can configure the bitmap before the cyclic-prefix length is detected, and the surplus bit (bit 6) is transparently ignored if the signal turns out to be extended CP.

Requirements

Target Platforms: Windows 11 Professional or Enterprise; Windows 10 Professional, Enterprise, or Education (64-bit)
