those in the lower gap, but inverted. To either side of the outermost transmit channels,
lower and upper adjacent channels can be defined as in common ACLR measurement
setups.

Asymmetrical gap channels
Gap channels between sub blocks can now also be asymmetrical, that is: channels in
the lower and upper gaps are not identical. For example, in
Figure 7-25 , the gap
between sub blocks A and B contains one lower channel (AB:Gap1L), but two upper
channels (AB:Gap1U, AB:Gap2U). Furthermore, the gaps between different sub blocks
need not be identical. For example, the gap between sub blocks A and B contains 3
gap channels, while the gap between sub blocks B and C contains only two gap chan-
nels (BC:Gap1L, BC:Gap2L, which are not identical to the lower gap channels in gap
AB.

Sub block and channel definition
The sub blocks are defined by a specified center frequency, RF bandwidth, and num-
ber of transmit channels.
