Abstract: A method, an apparatus, and a system for detecting a radio network problem are disclosed. The method includes: when a radio network problem occurs on a user equipment (UE), a first base station controlling a cell that a radio resource control (RRC) connection established with the UE, receives problem information about the radio network problem sent by the UE, in a procedure of re-establishing the RRC connection by the UE, and sends the problem information to a second base station controlling a cell where the radio network problem occurs.

Abstract: A method includes: obtaining a first sequence corresponding to a basic code length N0; determining N to-be-encoded bits, where the N to-be-encoded bits include N2 fixed bits, and N is greater than the basic code length N0; extending the first sequence to obtain a second sequence; determining locations of the N2 fixed bits in the N to-be-encoded bits based on polar channel serial numbers indicated by first N2 elements in the second sequence; and performing polar encoding on the N to-be-encoded bits to obtain encoded bits. The locations of the fixed bits in the N to-be-encoded bits are determined based on the second sequence, and the second sequence is obtained by extending the first sequence corresponding to the basic code length N0.

Abstract: Method and apparatus for transmission and reception with polar codes are provided to support up to 16 permutations or transformation mappings. For example, 16 versions of copies able to be soft-combined for PBCH or any other data channel or control channel are suggested if the mother code length is 256 or 512 or 1024. With the new design, up to 16 different versions can be used to soft combined to improve the performance. Some sequences are provided as examples to support 16 different permutation patterns. The inverse of these sequences also have the feature to support 16 different permutation patterns.

Abstract: A management method includes receiving, by a first management unit, a first management request, where the first management request carries requirement information of a network slice or indication information, and the indication information is used to obtain the requirement information of the network slice. The method further includes obtaining, by the first management unit, requirement information of a first subnet based on the requirement information of the network slice, and determining, by the first management unit, requirement information of a first network resource required by the first subnet, where the requirement information of the first network resource is used to select, create, configure, activate, or request a first network resource instance that satisfies the requirement information of the first network resource.

Abstract: Aspects of this disclosure provide a technique for implementing polar encoding with incremental redundancy HARQ re-transmission. In particular, a transmitter encodes a message using different polar codes to obtain a first codeword and a second codeword that is twice the length of the first codeword, and transmit the first codeword as an original transmission, and the second half of the second codeword as a re-transmission without transmitting the first half of the second codeword. Information bits that are common to both the first codeword and the second half of the second codeword is mapped to more-reliable bit-locations in the second half of the second codeword. Decoded bit values for the common information in the original transmission and retransmission is compared by the receiver to perform a parity check.

Abstract: A low density parity check (LDPC) channel encoding method is used in a wireless communications system. A communication device encodes an input bit sequence by using an LDPC matrix, to obtain an encoded bit sequence for transmission. The LDPC matrix is obtained based on a lifting factor Z and a base matrix. The base matrix may be one of eight exemplary designs. The encoding method can be used in various communications systems including fifth generation (5G) telecommunication systems, and can support various encoding requirements for information bit sequences with different code lengths.

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: Example polar coding methods and apparatus are described. One example method includes determining a sequence used to code to-be-coded bits. Polar coding is performed on the to-be-coded bits by using the sequence to obtain coded bits. The sequence is used to represent a reliability order of N polarized channels, N is a mother code length of a polar code, and N is a positive integer power of 2.

Abstract: Embodiments of this application disclose a polar coding method, apparatus, and device, so as to reduce storage overheads of a system. A sequence for polar coding is obtained based on a length M of a target polar code, wherein the sequence comprises L sequence numbers, ordering of the L sequence numbers in the sequence is the same as ordering of the L sequence numbers in a maximum mother code sequence, wherein the maximum mother code sequence is obtained by sorting N sequence numbers of N polarized channels in ascending order or descending order of reliability metrics, wherein L and N are integer power of 2, M is smaller than or equal to L, L is smaller than or equal to N.
