Abstract

The present application relates to the field of communications and provides in an embodiment an enhanced discovery reference signal mapping method and device, enabling enhanced coverage of a discovery reference signal. The method comprises : a base station determining, according to enhanced cell coverage capability, information relating to a time frequency resource for carrying an eDRS, wherein the eDRS includes one or more of an enhanced synchronization signal, an enhanced reference signal, an enhanced physical broadcast channel, and an enhanced data channel, and the information relating to the time frequency resource includes one or more of a resource occupation amount, a position in the frequency domain, and a position in the time domain of the eDRS; the base station mapping, according to the information relating to the time frequency resource, the eDRS; the base station sending to a terminal the time frequency resource mapped with the eDRS; and the terminal receiving, according to the information relating to the time frequency resource, an eDRS sent by the base station. The solution according to the embodiment of the present application is applicable in the process of eDRS transmission.

Description

【Technical field】 [0001] The present invention relates to the field of communication technology, in particular to a method and device for enhanced sounding reference signal mapping. 【Background technique】 [0002] The communication system provides communication services for user terminals (such as mobile phones) through wireless access network equipment (such as base stations) and core network equipment (such as home location registers). At present, due to the special geographical location of some user terminals (such as the water meter / electricity meter in the basement), when the user terminal in this geographical location communicates with the base station, the signal penetration loss is large and the channel fading is large, which ultimately makes the communication of the user terminal decline in quality. Therefore, it is necessary to expand the signal energy or quality between the user terminal and the base station, and to enhance the coverage of each physical channel o...
