Abstract: Embodiment techniques map parity bits to sub-channels based on their row weights. The row weight for a sub-channel may be viewed as the number of “ones” in the corresponding row of the Kronecker matrix or as a power of 2 with the exponent (i.e. the hamming weight) being the number of “ones” in the binary representation of the sub-channel index (further described below). In one embodiment, candidate sub-channels that have certain row weight values are reserved for parity bit(s). Thereafter, K information bits may be mapped to the K most reliable remaining sub-channels, and a number of frozen bits (e.g. N−K) may be mapped to the least reliable remaining sub-channels. Parity bits may then mapped to the candidate sub-channels, and parity bit values are determined based on a function of the information bits.

Abstract: Embodiments of the present invention provide a method and an apparatus for transmitting pattern information. The 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 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 enables 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. The embodiments of the present invention improve scheduling accuracy and efficiency.

Abstract: The present invention provides a method for determining an unnecessary handover and a base station. The method includes: if a user equipment UE is handed over from a first cell to a second cell, and then handed over from the second cell to a third cell, determining, by a base station, a time threshold corresponding to a UE characteristic attribute parameter of the UE, and a time of stay of the UE in the second cell; determining, by the base station according to the time threshold corresponding to a UE characteristic attribute and the time of stay of the UE in the second cell that are determined, whether an unnecessary handover of the UE occurs; and determining that an unnecessary handover of the UE occurs if the time of stay is shorter than the time threshold. The present invention optimizes a method for determining whether an unnecessary handover occurs.

Abstract: The application provides a method for determining a packet forwarding path, a network device acquires device information of the network device and interface information of the network device, so that the network device can send the device information of the network device and the interface information of the network device to a control device by using an IGP, so that the control device determines a packet forwarding path from the network device to the control device according to the device information of the network device and the interface information of the network device. Each network device that sends device information and interface information of the network device by using an IGP does not need to compute a packet forwarding path from the network device to a corresponding control device; therefore, decreasing a processing burden of the network device.
