Abstract: The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as a long term evolution (LTE). Various examples of the present disclosure provide a method of allocating sounding reference signal (SRS) resources. A base station of a target cell receives information of first cell edge terminals in an adjacent cell transmitted by the adjacent cell. The base station allocates SRS resources for a terminal in the target cell according to information of second cell edge terminals in the target cell and the information of the first cell edge terminals, and transmits information of the allocated SRS resources to the terminal. According to the mechanism, when there are cell edge terminals in both the target cell and the adjacent cell, it can be guaranteed that all SRS resources allocated to cell edge devices in the target cell are orthogonal to those allocated to cell edge devices in the adjacent cell. Thus, the impact of pilot contamination on system performances may be remarkably reduced.

Abstract: The present disclosure discloses cache-based data transmission methods and apparatuses. The method is implemented as follows. An apparatus where a caching node is located reports a caching capability to a network side, and the caching node is configured to cache data. The network side sends a cache indicating parameter to the apparatus where the caching node is located, and maintains a data list. Wherein, the cache indicating parameter is configured to control the caching node to cache the data which has the property of high repetition probability and/or high cache utilization, and the data list is a list of the data cached in the caching node. When the caching node has cached data requested by a UE, the UE obtains the requested data from the caching node.
