    Abstract: The present application relates to the technical field of wireless communication, and particularly relates to a channel encoding method and device, for use to solve the problem that at present, there is no physical broadcast channel polar encoding method in a 5G scene. Embodiments of the present application relate to determining a polar mother code length according to transmission resources of a channel; performing polar encoding, according to the polar mother code length, on data needing to be transmitted over the channel to obtain target encoding data; processing the target encoding data according to the length of an actual bearer of the transmission resources; and determining, according to the processed target encoding data, encoding data needing to be transmitted over the channel. The embodiments of the present application achieve determining encoding data according to an actual transmission resource length of a channel, so that the processed encoding data can be ensured to be accurately transmitted over the channel.

    Abstract: Disclosed are a method, device, and system for reporting a channel quality indicator (CQI), applicable in solving the problem in coordinated multipoint transmission technology of the incapability of a network side to execute accurately resource distribution and scheduling due to the incapability of the network side to have accurate knowledge of the interference that a terminal is being subjected to. The method is: on the basis of measurement reference signals transmitted by each device in a measurement collection, the terminal feeding back to a network side device an initial CQI of each device in the measurement collection; on the basis of the initial CQI of each device fed back by the terminal, and of channel matrix reference information fed back by the terminal, the network side device calculating a target CQI of the terminal. This allows the network side to learn accurately the interference that the terminal is being subjected to, thus allowing for accurate execution of terminal scheduling, resource distribution, and MCS selection, for effectively improved system throughput in coordinated multipoint transmission, and for improved system performance.

    Abstract: A method and apparatus for transmitting downlink control information. In the present invention, transmitted downlink control information at least comprises one or more of the following information fields: a first information field used for indicating the frequency domain resources occupied by the data resources scheduled by the DCI, a second information field used for indicating the time frequency resources occupied by the data resources scheduled by the DCI, and a third information field used for indicating the scheduled N users. As the resource size occupied by the transmission resources in the frequency domain and/or in the time domain is indicated by means of the downlink control information, transmission of downlink control information can be implemented in flexible resource allocation scenarios having variable transmission time intervals.
