Embodiment Construction
[0051] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0052] The base station system provided by the present invention is composed of BBU and RRU. By combining the baseband signals transmitted by the predetermined multiple RRUs into one baseband signal, when the predetermined multiple RRUs perform signal interaction with the upper layer, since there is only one path after the combination Signals, so that from the perspective of high-level control, the high-level is only performing signal interaction with one entity, and the reserved multiple RRUs are logically regarded as a logical entity by the high-level, so the coverage area of the predetermined multiple RRUs becomes a logical entity. In the coverage area, multiple RRUs are scheduled to be used as a logical cell (i.e. to realize the structu...
