Abstract: The middle subcarrier of the baseband OFDM signal of each numerology may need to be shifted appropriately with respect to other numerologies to comply with a nested grid. These shifts can be signalled to the UE with an associated overhead. Methods and systems are provided to reduce overhead for OFDM communication. Reduced overhead can translate into increased bandwidth for the system, and/or reduced power/battery consumption in the UE. A transmitter generates an OFDM signal associated with a first subcarrier spacing of a first numerology (μ), a middle subcarrier frequency of a set of usable resource blocks (RBs) of the first numerology being offset from a carrier frequency by a first offset having a value (k0,xμ) in units of subcarriers, the value of the first offset being defined by a specific formula. The transmitter transmits the OFDM signal according to the first subcarrier spacing and the first offset.

Abstract: Embodiments of the present invention provide a method and an apparatus for transmitting broadcast-multicast single-frequency network measurement data, where second measurement data is acquired by preprocessing acquired first measurement data, and the second measurement data is sent to a base station. Because the second measurement data is obtained after the first measurement data is preprocessed, a size of the second measurement data is smaller than that of the first measurement data, thereby reducing a transmission overhead.

Abstract: A frequency hopping processing method and apparatus are disclosed, where user equipment receives frequency hopping information, which is sent by a network device, of an extended transmission time interval (TTI); and determines a frequency hopping area of the extended TTI according to the frequency hopping information of the extended TTI. The frequency hopping area of the extended TTI and a frequency hopping area of a normal TTI do not overlap in frequency, and during M-PUSCH frequency hopping of each extended TTI, the user equipment can hop into a corresponding M-PUSCH frequency hopping area according to a preset frequency hopping pattern, and does not hop into a PUSCH frequency hopping area, so that a resource conflict does not exist when M-PUSCH frequency hopping of an extended TTI and PUSCH frequency hopping of a 1 ms TTI are performed at the same time.
