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: A method, a device, and a system for triggering a scheduling request (SR) to meet quality of service (QoS) requirements of different services in a New Radio (NR) vehicle to everything (V2X) system and to avoid or reduce unnecessary SR triggering. The method includes that a network device sends a first message to a terminal device, where the first message includes a first identifier and one or more configuration parameters corresponding to the first identifier. The first identifier is of a first logical channel, and the first logical channel is of a sidelink (SL) radio bearer. Alternatively, there is a mapping relationship between the first identifier and the first logical channel.

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: 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.

Abstract: A scheduling method, scheduling algorithm training method, related system, and storage medium are provided including the scheduling method being applied to a scheduling control system, which includes K network devices, and K is an integer greater than 1. The method further includes a first network device that obtains target state information of a first area, where the target state information includes network state information and user data packet cache information. The first network device generates first scheduling information based on the target state information of the first area and a first target sub-policy network, where the first target sub-policy network is a target sub-policy network that is in K target sub-policy networks and that corresponds to the first network device. The first network device delivers the first scheduling information to a terminal in the first area.

Abstract: A method includes: A transmit end obtains P QAM symbols; the transmit end performs IDWT or DWT on the P QAM symbols, to obtain a first signal matrix with N rows and M columns, and transposes the first signal matrix, to obtain a transposed first transpose matrix, where P, N, and M are all positive integers; and the transmit end outputs the transposed first transpose matrix. Correspondingly, a receive end obtains a second signal matrix with M rows and N columns; the receive end transposes the second signal matrix, to obtain a transposed second transpose matrix; and performs DWT or IDWT on the second transpose matrix, to obtain P QAM symbols.

Abstract: A macro image shooting method uses at least two macro cameras having different focal lengths. When a zoom ratio is within a first ratio range, an image captured by a first macro camera is displayed in a viewfinder frame. When the zoom ratio is a camera switching ratio, the image displayed in the viewfinder frame is switched from the image captured by the first macro camera to an image captured by a second macro camera. When the zoom ratio is greater than the camera switching ratio and is within a second ratio range, the image captured by the second macro camera is displayed in the viewfinder frame.
