5.3.2 RRM Groups
While the 9150 can operate as a Remote Radio Module (RRM, see “Connectivity
Options: RRM Mode” on page 117), it can also control other RRMs. For a 9150 to
control RRMs, RRM groups must be configured. Once an RRM group has been
defined, from one to four RRMs can be members of a group (see “RRM Group
Menu” on page 126).
All RRMs in a group operate on the same radio channel. The 9150 coordinates the
transmissions of all the RRMs in a group (for this reason, the controlling 9150 is
sometimes referred to as the “Timeplexing Master”).
5.3.2.1 Configure New RRM Group
In this screen, shown on the next page, the user can set options for a new RRM
group. Each RRM must be a member of an RRM group; there may be more than one
RRM group configured in the 9150. An RRM group may contain from one to
four RRMs.
This screen is very similar to the one in “Connectivity Options: Base Station Mode”
on page 112, the difference being that the parameters configured in those radio
menus apply to the TRX7370 radio resident in the 9150, while the parameters con-
figured here apply to the other, remote 9150s (the RRMs).
