Abstract: The application provides manner for communicating channel state information (CSI) in a communication network. A preset length is used for equalizing lengths of CSI to be reported. The preset length is determined based on a quantity of CSI-reference signal (RS) ports. A communication device determines whether a total length of one or more indication information items to be included in the CSI is less than the preset length. If the total length of the one or more indication information items to be included in the CSI is less than the preset length, the communication device adds one or more padding bits, to obtain a CSI bit sequence including the one or more indication information items and the one or more padding bits. A total length of the CSI bit sequence is consistent with the preset length. The communication device then outputs the CSI bit sequence.

Abstract: Embodiments of this disclosure enhance the error detection performance of parallel polar encoding by cross-concatenating parity bits between segments of information bits transmitted over different sets of sub-channels. In one embodiment, a first segment of information bits is transmitted over a first set of sub-channels, and at least a second segment of information bits, and a masked parity bit, are transmitted over a second set of sub-channels. A value of the masked parity bit is equal to a bitwise combination of a first parity bit computed from the first segment of information bits and a second parity bit computed from the second segment of information bits. The bitwise combination may be a bitwise AND, a bitwise OR, or a bitwise XOR of the respective parity bits.

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.

Abstract: Embodiments of the present disclosure provide example methods and apparatuses for transmitting pattern information. One example method for transmitting pattern information includes obtaining pattern information and sending the pattern information to UE. The first pattern information indicates that the spectrum of the first cell is allocated to the first RAT in a first plurality of sub-frames and that the spectrum of the first cell is allocated to the second RAT in a second plurality of sub-frames. The first pattern information enables at least one of the UE to select any sub-frame in the first plurality of sub-frames to measure a CRS if the UE RAT pattern corresponds to the first RAT or the UE to select any sub-frame in the second plurality of sub-frames to measure the CRS if the UE RAT pattern corresponds to the second RAT.

Abstract: A system, base station and method are disclosed for detecting a radio network problem. For a handover failure occurs on a user equipment (UE), a first base station receives, problem information about the occurred handover failure from the UE, after a radio resource control (RRC) connection is reestablished or established between the UE and a cell controlled by the first base station. The first base station then transmits the received problem information to a second base station controlling a cell where the handover failure occurs. In this way, the network side can automatically identify and detect the handover failure. As such, the network can perform self-adjustment and optimization, therefore improving the network performance and satisfying use requirements of users.
