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: A method and an apparatus for determining an RBG size are provided. In the method, a network device or a terminal determines an RBG size set, where the RBG size set may include one or more possible RBG sizes; and determines a first RBG size included in the RBG size set. The network device allocates a resource to the terminal by using the determined first RBG size. The terminal determines, based on the determined first RBG size, the resource allocated by the network device to the terminal.

Abstract: Methods, systems and apparatus for communications are provided. In the methods, a network device sends first indication information to a terminal device, where the first indication information indicates a first bandwidth part (BWP) that is to be activated, other than a primary BWP, to the terminal device, and the primary BWP is a BWP that remains activated between the terminal device and the network device. The network device communicates with the terminal device in an activated first BWP and the primary BWP.

Abstract: Various embodiments provide a communication method and a communications apparatus. In those embodiments, a terminal device receives first indication information and second indication information from a network device. The first indication information indicates a position of a first reference point, the second indication information indicates a first quantity, the first quantity is a quantity of offset units between the first reference point and a second reference point, and the second reference point is an endpoint of a first physical resource block (PRB). The terminal device determines a position of the first PRB based on the first indication information, the second indication information, and an identifier of a subcarrier corresponding to the first reference point. Therefore, the terminal device can complete, without learning of a system bandwidth, a process of determining a PRB corresponding to a start point of a PRB number in the system bandwidth.
