Abstract: A method includes receiving a task processing request from user equipment (UE) and obtaining application layer information for the task processing request and capability information of the UE for the task processing request. The method also includes obtaining access stratum information. The method further includes sending, based on the capability information, the application layer information, and the access stratum information, processing indication information to an apparatus for executing the task. The processing indication information instructs the apparatus to process the task corresponding to the task processing request. The apparatus for executing the task is at least one of the UE, an access network device, a core network device, or an Internet server.

Abstract: A method and a device for signal processing in a communication system are provided. The method includes: performing sampling and time-frequency transform on a received first time domain signal to obtain a first frequency domain signal; performing modulus operation on the first frequency domain signal with respect to a preset threshold to obtain a second frequency domain signal; performing inverse time-frequency transform on the second frequency domain signal to obtain a second time domain signal, and performing despreading on the second time domain signal. The embodiments of the present invention can avoid the problem in the prior art that not only the NBI signal but also the SS signal which is a useful signal are filtered out, which results from frequency domain signals of a certain number of frequency points being set to zero, and thereby improve the reliability of signal reception.
