A wireless communication device receives OFDM radio signals having different numerologies (i.e. different sub-carrier spacing) and determines whether the transmission, by one or more transmitting nodes, of the OFDM signals are coordinated. The meaning of “coordinated” is to be understood as the OFDM signals are time-synchronized and the determination of whether the OFDM signals are coordinated may involve such actions as reading broadcast or receiving configuration message transmitted in the system, determining a relation (for instance cell/access point beam identity) between transmitted synchronization or reference signals. If the OFDM signals are determined to be coordinated, time and/or frequency offset for the second OFDM signal having the second subcarrier spacing is derived based on the time and/or frequency offset associated with the first OFDM signal having the first subcarrier spacing.
A method performed by a wireless communication device in an orthogonal frequency-division multiplexing, OFDM, wireless communication system for determining a first offset parameter and a second offset parameter associated with a respective received first OFDM signal and a second OFDM signal having a respective first and second subcarrier frequency spacing, the method comprising:
A wireless communication device for an orthogonal frequency-division multiplexing, OFDM, wireless communication system for determining a first offset parameter and a second offset parameter associated with a respective received first OFDM signal and a second OFDM signal having a respective first and second subcarrier frequency spacing, the wireless communication device comprising input/output circuitry, a processor and a memory, said memory containing instructions executable by said processor whereby said wireless communication device is operative to:
A nontransitory computer-readable storage medium comprising a computer program comprising instructions which, when executed on at least one processor in a wireless communication device in an orthogonal frequency-division multiplexing, OFDM, wireless communication system, cause the wireless communication device to carry out a method for determining a first offset parameter and a second offset parameter associated with a respective received first OFDM signal and a second OFDM signal having a respective first and second subcarrier frequency spacing, the method comprising:
