47 New Features The main features of ZXG10 B8018 is shown below:  DTRU technology;  DPCT-dual power combining Transmission;  DDT-delay diversity transmission  4-way diversity reception;  IRC-Interference Rejection Combining;  intelligent power on/off;  IP Abis-interface. New Features

48 The DTRU is very flexible and can be used for several purposes. Its two TRXs, for instance, can be used separately (the same with ever)or both,both refers to by DPCT to improve the downlink and by four-way diversity to improve the uplink, they can be configured to create a super TRX. New Features

49 One DTRU can easily be used to extend coverage New Features

50 DPCT---- Dual Power Combining Transmission:  When seeking greater cell range it is crucial to have a strong signal from the BTS to the handset. This is often referred to as downlink capability. This is what a handset presents as signal strength in the display. In configurations intended for maximum coverage, Dual Power Combining Transmission (DPCT) feature doubles the output power from the BTS cabinet, resulting in a significantly larger coverage area. New Features

51 DPCT principle New Features

52 DPCT implementation in B8018 New Features

53 DDT ----Delay Diversity Transmission  Purpose: supports downlink transmitter diversity (the mobile phone combines the best of two signals).  Implementation: by transmitting the same information on two TRXs with a short delay and different antennas.  using only a simple software command, operators can convert the base station from a two transceiver operational mode into the “DDT" mode, where the two transceivers work together as one virtual transceiver, so extending the range.  cellular downlink performance is increased by at least 3.0 decibels (dB) at the cell border, reducing the number of sites needed by up to 30 percent over any conventional base station coverage network. New Features

54 DDT implementation in B8018 Delay Diversity Transmission New Features

55 4 div RX ― 4 diversities reception  The majority of radio networks today have limited range due to weak uplink signals from handsets. The best way to overcome an unbalanced link budget is to ensure good receiver capability in the base station. With the addition of a second antenna system in the cell, we enable 4-Way Receiver Diversity (4WRD), and this provides a total uplink that compensates for weak handset signals.  The combination of DPCT with fully compensated uplink based on 4-way Receiver Diversity comprises our Supreme Coverage solution. New Features

56 IRC ― Interference Rejection Combining  Another way to increase the capacity, more advanced detection techniques have been implemented - Interference Rejection Combining (IRC)  In maximum ratio combining (MRC) each signal is weighted with its signal-to-noise ratio to achieve optimum performance in white noise environments, i.e. the noise signal is uncorrelated in time.  IRC, on the other hand, takes the correlation properties of CO- channel interferers into account to suppress them, and therefore is able to achieve much better performance in co-channel limited environments than MRC. New Features

57 Int. Pwr on/off ― Intelligent power on/off  In order to reduce OPEX of operator, when traffic decrease to certain value or in idle mode, this scheme automatically to turn off part of Modules of B8018 to save power.  When traffic increase to certain busy threshold, this scheme automatically to turn on sleep module to balance the traffic.  The principle is as follows: CMB is able to control the switch of all board (mainly is DTRU) in rack except interface board (EIB/FIB) and CMB. New Features

58 IP Abis  One of the primary advantages of employing IP-based transport is the ease of maintenance arising from convergence of core and RAN networks.  Other advantages include economic benefits and capacity benefits New Features
