Detailed Description

A Channel access manager that sees the channel always free for transmitting.

This channel access manager is installed by default in NR instances.

always_on_usage

This is the CAM that is created by default. However, if you want to set it manually, you can invoke the helper function before installing the gnb:

  nrHelper->SetGnbChannelAccessManagerTypeId (NrAlwaysOnAccessManager::GetTypeId());
  ...
  nrHelper->InstallGnb ...

or the UE-side:

  nrHelper->SetUeChannelAccessManagerTypeId (NrAlwaysOnAccessManager::GetTypeId());
  ...
  nrHelper->InstallUe ...

The type of the channel access manager cannot be changed after the helper has installed the UE or the GNB node.
