Ø Handling the handshaking among RF, Encoding/Decoding, Radio
Channel Measurements and Line Interface Module
Ø Processing the Layer-2 and Layer-3 protocol between RP and RPCU.
Ø The wireline transport between an RP and RPCU can be provided by
HDSL line interfaces. The RP shall convert the RF channel rate of
384Kbps into the appropriate line transmission bit rate.
n RF
Ø The channel spacing shall be 300KHz. The port shall receive on the low
band, 1850 to 1910MHz, and transmit on the high band, 1930 to
1990MHz of the duplex frequency allocation.
Ø By performing the diversity combining or selection at the RP, the line
transmission rate to the network can be at the channel rate. Diversity
selection is performed after decoding both branches. The error free word
is chosen, with the corresponding received power and quality indicator
used for power control. If there is a tie, then the branch with the higher
power shall be selected.
Ø The transmit and receive frequencies shall be synthesizer-controllable,
with the frequency specified by the control signaling.
n Power Source
Ø Power Source can convert line power to 5Vdc to power up the RP and let
RP work properly.
Ø Power Source can split the HDSL signaling and Power from line input.
