Abstract:
Various embodiments provide a data communication method. Under the method, a transmit end maps each code block group CBG in N CBGs to each layer in a corresponding layer group based on a correspondence between the N CBGs and N layer groups. Each layer group includes at least one layer, and N is a positive integer. The transmit end then sends data to a receive end. T transport block corresponding to the data includes the N CBGs. In this way, a mapping relationship between a CBG and a layer group is established by grouping layers, so as to improve data reception quality, through interference cancellation, for transmission among different layer groups, and ensure adaptivity to a CBG-based retransmission feedback, thereby optimizing transmission performance of an entire communications system.

Embodiments provide a data processing method. The method can include obtaining a key value. The method can include performing K hash operations on the key value separately by using K different hash function. In this way, K hash values can be obtained. The method can include calculating K addresses based on the K hash values. Each of the K addresses can have a one-to-one association with one of K words in a target data block such that a given address of the addresses indicates a bit in a word associated with the given address. The method can include setting or a reading a parameter corresponding to a bit indicated by each of the K addresses, where the bit is in a word associated with each of the K addresses, based on the read parameter, whether the key value belongs to the Bloom filter.

Abstract:
The present disclosure relates to the communications field, and provides a frame synchronization method, user equipment, and a base station, to implement frame time synchronization in a high-low frequency hybrid communications system. In one example method, a user equipment completes synchronization of a first frequency frame, determines a first moment of the synchronization of the first frequency frame, obtains a receive time difference, and completes synchronization of a second frequency frame according to the receive time difference and the first moment. The receive time difference is a time difference between a moment at which the user equipment receives the second frequency frame and a moment at which the user equipment receives the first frequency frame.

Abstract:
A positioning method and apparatus. A location management network element sends first indication information to a network device, where the first indication information is useable by the network device to measure a signal that is sent by a terminal device and that is reflected by a reflection panel. After receiving the first indication information, the network device measures the signal reflected by the reflection panel, and reports a measurement result to the location management network element. The location management network element determines a location of the terminal device based on location information of the network device, location information of the reflection panel, and the measurement result. In response to a line-of-sight (LOS) path between the terminal device and the network device being blocked, a signal on the LOS path cannot be directly transmitted and measured.
