Abstract: The application provides a channel encoding method, an encoding apparatus, and a system. A bit sequence X1N is output by using X1N=D1NFN, where D1N is a bit sequence obtained after an input bit sequence u1N is encoded based on locations of K to-be-encoded information bits in an encoding diagram that has a mother code length of N, u1N is a bit sequence obtained based on the K to-be-encoded information bits, and FN is a Kronecker product of log2 N matrices F2. A design considers that the locations of the K to-be-encoded information bits in the encoding diagram that has a mother code length of N include a row location index set H of the information bits in the encoding diagram and a layer location index set M of the information bits in the encoding diagram, where 0≤H≤N, and 0

Abstract: A data transmission method, a terminal, and a network device are provided. In embodiments of the present disclosure, a terminal sends, in a grant-free mode, first data to a network device by using a grant-free resource, and if the terminal needs to switch from the grant-free mode to a grant mode, the terminal sends, in the grant mode, second data to the network device by using a grant resource. When the terminal initially transmits the first data in the grant-free mode, if the terminal needs to switch from the grant-free mode to the grant mode, the terminal may fall back to the grant mode and transmit data in the grant mode.

Abstract: A data transmission method, a terminal, and a network device are provided, to improve reliability of data transmission performed by a terminal in a grant-free mode. In embodiments of the present invention, a terminal sends, in a grant-free mode, first data to a network device by using a grant-free resource, and if the terminal needs to switch from the grant-free mode to a grant mode, the terminal sends, in the grant mode, second data to the network device by using a grant resource. When the terminal initially transmits the first data in the grant-free mode, if the terminal needs to switch from the grant-free mode to the grant mode, the terminal may fall back to the grant mode and transmit data in the grant mode. In this way, reliability of data transmission is improved and a success rate of data transmission is improved to a relatively great extent.

Abstract: This application provides a method for communicating a modulation and coding scheme (MCS). A terminal device obtains a modulation order, a code rate, or a spectral efficiency, determines an index of a reference MCS from a mapping table based on the obtained modulation order, code rate, or spectral efficiency, and reports the index of the reference MCS to a network device. The mapping table includes one or more mapping relationships between an MCS index and a modulation order, a code rate, or a spectral efficiency. The terminal device may process uplink or downlink data based on the determined MCS, thereby improving data transmission reliability.

Abstract: A first Control Node (CNd) and a method therein, for selecting a serving CNd for a User Node (UNd) by communication with at least a second CNd. The first CNd is configured to receive an uplink beacon measurement report comprising at least one measurement of an UNd uplink beacon, from at least one Access Node (ANd) controlled by the first CNd. The first CNd is further configured to preliminarily select a serving CNd for the UNd, based on the received uplink beacon measurement report concerning the UNd; confirm the preliminarily selected serving CNd by communication with the second CNd; and, select serving CNd for the UNd when the preliminarily selected serving CNd is confirmed by the second CNd.
