摘要： Example resource allocation methods and apparatus are described to resolve a problem of resource congestion and collision occurring in a communications system when virtual resource blocks (VRBs) scheduled for different terminal devices are mapped to physical resource blocks (PRBs). In one example method, system bandwidth of the communications system is divided into a plurality of fixed interleaving regions. Therefore, a network device can indicate a type of a virtual resource unit in a form of a frequency domain range occupied by one interleaving region. Using the foregoing solution can enable the network device to set the type of the virtual resource unit more conveniently.

摘要： Disclosed are methods and systems for determining, by a terminal device, downlink control information that includes a first information field and a second information field. The first information field is used to indicate whether to switch an active bandwidth part of a terminal device. When the first information field indicates to switch the active bandwidth part of the terminal device, the second information field is used to indicate one or more active bandwidth parts and frequency domain resource location of a data channel in the active bandwidth parts to switch; or when the first information field indicates not to switch the active bandwidth part of the terminal device, the second information field is used to indicate a frequency domain resource location of a data channel in a currently accessed active bandwidth part. A working bandwidth part of the terminal device can be indicated, and resource utilisation is improved.

摘要： A communications method and apparatus are provided. The method includes: determining one or more occasions on which a first channel is sent; and sending the first channel on the one or more occasions to at least one terminal device. The first channel carries first information. The first information includes one or more information blocks. Each information block corresponds to one of the at least one terminal device. Each information block corresponds to a different terminal device. Each information block includes one first information field set that is used to indicate information about detection performed on a second channel by a terminal device corresponding to the information block in which the first information field set is located.

摘要： A data transceiving method includes: receiving a first reference signal transmitted on a subcarrier in a target physical resource block, and performing, according to a first mapping rule, corresponding processing on the first reference signal received from the subcarrier in the target physical resource block, where the first mapping rule defines at least mapping of the first reference signal to 10 specified subcarriers in a physical resource block, none of the 10 specified subcarriers are in a DC subcarrier candidate set, and the first reference signal includes a PCRS. In the embodiments of this application, only the 10 specified subcarriers in the physical resource block that are not used as DC subcarriers are selected to transmit the first reference signal, and no additional DC subcarrier is set. In this way, a quantity of downlink subcarriers in a system does not change dynamically.
