Abstract: An interference cancellation method and device are disclosed. In a process of performing cell reestablishment or cell handover, for any interference cancellation parameter previously received from a network-side device, a user terminal can continue to apply the interference cancellation parameter to perform an interference cancellation operation according to a specified first interference cancellation parameter application rule or first instruction information delivered by the network-side device, or release or no longer apply the interference cancellation parameter. In this way, a currently existing problem that a user terminal cannot know how to process a previously received interference cancellation parameter in a process of performing cell reestablishment or cell handover can be resolved, and further, an objective of improving an interference cancellation effect can be achieved.

Abstract: Embodiments of the present invention disclose a random access method and an apparatus. According to the random access method disclosed in the embodiments, first downlink assignment information is obtained in a manner of a mapping relationship between first downlink assignment information and a preamble, where the first downlink assignment information is downlink assignment information used by a random access response message, and scheduling signaling of the random access response message does not need to be retransmitted by using the PDCCH channel, thereby resolving problems of a channel resource waste and an access delay in an existing random access method. The problems are caused because the PDCCH channel is used to retransmit the scheduling signaling of the random access response message.

Abstract: Resource scheduling includes pre-dividing a resource block RB into a plurality of sub-RBs and scheduling a UE by using a resource scheduling indication during data transmission to perform data receiving or sending in a position of a corresponding sub-RB. The resource block RB is pre-divided into a plurality of sub-RBs and during data transmission the UE is scheduled by using the resource scheduling indication to perform data receiving or sending in the position of the corresponding sub-RB, thereby improving resource utilization efficiency during transmission of a small data service and improving transmission efficiency of small data.
