An apparatus and method for a multi-service transmitter of an OFDM base station (BS) in a mixed numerology radio access network, wherein the transmitter uses a common cyclic prefix across all service types to eliminate inter-numerology interference (INI) by using a new Frequency Re-sampler (VR) component in the transmitter that converts streams of those services with smaller FFT sizes into a common larger FFT size in the frequency domain, which in effect increases their number of samples. The VR simply causes a multi-service transmitter to mimic a single-service transmitter thereby reducing the required number of ZF precoders to one and causing much fewer number of precoding operations. The transmitter sends resource configuration regarding the use of common CP for all services to each connected UE.

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

Methods and techniques are described for reducing PAPR in a system with multiple numerologies. The PAPR is reduced by means of minimization of a cost function including PAPR for some predefined parameters. For example, PAPR may be minimized for phase and/or amplitude and/or time/cyclic shift adjustment to adjust OFDM symbol phase and/or amplitude, or for number and/or type of numerologies to be combined for the transmission.
