increase the efficiency of the transmitter and the reliability of the power
amplifier, and minimize the transmitter interference.
Baseband Processing
The baseband processing implements the function of the physical layer on
the Um interface, processing all full-duplex channel baseband data on one

In the uplink direction, they are digital demodulation, decryption,
deinterleaving, channel decoding and rate adaptation.

Signaling Processing
The OB06 signaling processing implements the following two functions:
1. Interconnection between the MS and BSS/NSS on the Um interface
layer
2. Management of some radio resources under the control of the BSC
Specifically, the OB06 signaling processing functions are wireless link layer
management function, dedicated channel management function, common

channel management function and TRX management function.
Wireless Link Management Function
This function supports the following procedures:
1. Link establishment indication procedure: This procedure allows the
OB06 to give the BSC an indication that an MS-originated link in multi-
frame mode has been established successfully. Through this indication,
frame mode has been established successfully. Through this indication,
the BSC establishes an SCCP link to the MSC.
2. Link establishment request procedure: This procedure allows the BSC
to request to establish a link in multi-frame mode on a radio channel.
3. Link release request procedure: This procedure allows the BSC to
request the OB06 to release a radio link.
4. Link release indication procedure: This procedure allows the OB06 to
give the BSC an indication that the MS-originated radio link has been
released.
5. Um L3 message transparent forwarding procedure in acknowledgement
mode: This procedure allows the BSC to request the OB06 to
transparently forward a Um interface L3 message in the
transparently forward a Um interface L3 message in the
acknowledgement mode.
6. Um L3 message transparent receiving procedure in acknowledgement
mode: This procedure allows the OB06 to give the BSC an indication
that a Um interface L3 message is received transparently in the
acknowledgement mode.
that a Um interface L3 message is received transparently in the
acknowledgement mode.
