Apparatus and method for an improved transmitter for multi-service radio networks

A transmitter system within a base station of a radio access network sending data on a broadcast radio channel to a plurality of User Equipment belonging to at least two different service types such that a first service is of lower numerology N0 than a second service of higher numerology N1, wherein the transmitter comprising components of:

• a. a frequency re-sampler subsystem executing the following sequential steps of (i) taking L1 times N1 point Inverse FFT of modulated frequency domain symbols of the second service to create corresponding L1N1 time domain symbols, (ii) multiplexing L1N1 time domain symbols to create a serial symbol stream, (iii) demultiplexing said stream into N0 parallel symbol streams, and (i) taking N0 point FFT of said N0 parallel time domain symbol streams to create N0 modulated frequency domain symbols;
• b. a ZF precoder subsystem applying precoding over N0 number of subcarriers to modulated frequency domain symbols of the first service and second service;
• c. an IFFT subsystem taking N0 point inverse FFT of the first service symbols and the second service symbols to generate time domain symbols of the first service and the second service;
• d. a common CP Adder subsystem prepending each time domain symbol generated of the first service with a CP of duration CP0, Prepending each consecutive L1 time domain symbols of the second service with a CP of duration CP0;
• and
• e. a physical resource configurator subsystem that configures UEs served by said base station for a plurality of services according to use of common CP for all numerologies.
