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 control channel establishing method, a forwarding point, and a controller. The method includes: sending, by a first FP, topology information of the first FP to a second FP by using the LLDP; receiving, by the first FP, first routing information that is sent by the controller and is used by the first FP to reach the controller, where the first routing information is generated by the controller according to the topology information of the first FP; and establishing, by the first FP, a second control channel with the controller according to the first routing information. The first FP does not need to run the IGP protocol, thereby avoiding that the first FP maintains an IGP neighbor relationship; moreover, the first FP does not need to store routing information for reaching another FP, which helps save storage resources and helps improve forwarding performance.

Abstract: A method for determining an auxiliary bit of a polar code and an apparatus. At least K sub-channels are determined based on reliability of a first sub-channel set, where the K sub-channels carry information bits. S sub-channel subsets are determined based on the first sub-channel set, an ith sub-channel subset in the S sub-channel subsets includes Ji sub-channels carrying auxiliary bits and Ki sub-channels in the K sub-channels. Sequence numbers of the Ji sub-channels carrying the auxiliary bits are after sequence numbers of the Ki sub-channels. The auxiliary bits are known redundancy check RC bits. Polar encoding is performed on the information bits and the auxiliary bits, to output polar-encoded data.

Abstract: Methods, devices, and computer-readable storage media are disclosed. In an example method, segmentation of to-be-encoded information bits of a length N into respective quantities of different types of segments is performed. The different types of segments are among (b−a+1) types of segments that correspond to (b−a+1) different segment code lengths. The (b−a+1) types of segments comprise a minimum-length segment that has the minimum segment code length of 2{circumflex over ( )}a and a maximum-length segment that has the maximum segment code length of 2{circumflex over ( )}b. The respective quantities of the different types of segments are determined based on the length N and a code rate in an orderly manner, wherein the orderly manner comprises firstly determining a quantity of the maximum-length segments and lastly determining a quantity of the minimum-length segments. Polar code encoding is performed on the respective quantities of the different types of segments of the to-be-encoded information bits.
