A receiver of a User Equipment in a mixed numerology multi-service OFDM radio access network receives a control message for resource configuration from the base station instructing the receiver to remove a common (fixed duration) cyclic prefix (CP) regardless of service type when demodulating received radio signals. Upon this instruction, the receiver implements the method of removing the common cyclic prefix (CP) every L time domain symbols wherein L=2for the service type that uses numerology μ. According to one embodiment, the common cyclic prefix (CP) duration is chosen by the base station as the cyclic prefix of the service type with longest OFDM symbol in its mix of services. The receiver eliminates inter-numerology interference (INI) by equalizing the number of subcarriers used by all service types and their CP regardless of each service type's numerology.
