Abstract: Disclosed are a communications method and device. The method includes: sending, by a network device, configuration information to a terminal device; determining, by the terminal device, channel state information CSI measurement behavior and/or CSI feedback related information, where the channel state information CSI measurement behavior and/or the CSI feedback related information are/is related to the configuration information; and performing, by the terminal device, CSI measurement based on the configuration information and the CSI measurement behavior and/or the CSI feedback related information, to obtain at least one piece of CSI, and sending all or some of the at least one piece of CSI to the network device. It can be learned that, in a scenario in which a plurality of transmission modes are supported, according to the foregoing method, the terminal device can measure CSI, and feed back the measured CSI to the network device.

Abstract: This application provides a synchronization signal sending method and receiving method, and an apparatus. In the method, a base station determines a frequency domain position of a target frequency resource based on a frequency interval of synchronization channels, wherein the frequency interval of synchronization channels is 2m times a predefined frequency resource of a physical resource block, and m is a preset nonnegative integer. The base station sends a synchronization signal by using the target frequency resource.

Abstract: Example control information transmission methods and apparatus are described. One example control information transmission method includes that a terminal device determines a transmission resource based on a receiving status of downlink data and a scheduling request transmission status. The transmission resource is one of N first resources or one of M second resources. The N first resources are corresponding to N receiving statuses of the downlink data, and the M second resources are used to transmit a scheduling request. N is a positive integer greater than 1, and M is a positive integer. The terminal device sends uplink control information on the transmission resource.

Abstract: A downlink channel decoding method, a downlink information transmission method, a user equipment, and a base station are provided. The downlink channel decoding method includes: determining, by a user equipment, a resource unit occupied by a DMRS; and decoding a downlink channel based on the DMRS transmitted on the resource unit. The present invention can enable different DMRS patterns to concurrently exist on an NCT carrier. In a downlink transmission process, a DMRS pattern used for downlink transmission is determined according to priorities of different channels and/or signals, which can ensure optimal performance of a high-priority channel and/or signal, and can further improve downlink transmission performance.
