Name Definition
Transmission gap pattern repetition count (TGPRC) Number of transmission gap patterns within the
transmission gap pattern sequence.
Transmission gap connection frame number (TGCFN) CFN of the first compressed frame of the first
pattern within the transmission gap pattern
sequence.
Transmission gap slot number
(TGSN)
Slot number of the first transmission gap within
the first radio frame of the transmission gap
pattern.
Transmission gap length 1
(TGL1)
Duration of the first transmission gap within the
transmission gap pattern.
Transmission gap length 2
(TGL2)
Duration of the second transmission gap.
Transmission gap duration
(TGD)
This is the distance, measured in slots, from the
beginning of the first transmission gap to the
beginning of the second transmission gap.
Transmission gap pattern length 1
(TGPL1)
Duration of first transmission gap pattern that
includes TGL1/2.
Transmission gap pattern length 2
(TGPL2)
Duration of the second transmission gap pattern
that includes TGL1/2.
Stop connection frame number
(Stop CFN)
CFN of the last radio frame.
Transmission gap pattern sequence identifier (TGPSI) This identifies the currently selected transmission
gap pattern sequence. Only one TGPSI is
supported at this time.
Transmission gap pattern sequence
(TGPS)
This lets you select whether or not to transmit the
current TGPSI. Active it will be transmitted,
inactive it will not be transmitted.
CM Method: SF/2 (spread factor divided by two) or
Puncturing
This determines the data processing mode used to
create the gaps.
Frame Struct: A or B A: Optimizes the gap length.
B: Optimizes the power control.
