Abstract

The invention discloses a TD-LTE (time division-long term evolution) macro base station indoor extension coverage system and a TD-LTE small cell radiofrequency front terminal component. The system comprises a first high-isolation transceiving antenna, a second high-isolation transceiving antenna, a first filter, a second filter, a third filter, a fourth filter, a first AGC (automatic gain control) receiving module, a second ALC (automatic level control) transceiving module, a second AGC receiving module, a second ALC transmitting module and a cellphone chip synchronous monitor module. The system has the advantages that uplink-downlink synchronous time control can be achieved with uplink-downlink time slot synchronous signals without increasing cost, and the signals of an outdoor TD-LTE macro base station are quickly extended to an indoor signal weak region, blind region or an area with low internet speed and poor user experience.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular, to a TD-LTE macro base station indoor extended coverage system and a TD-LTE small base station radio frequency front-end component. Background technique [0002] With the large-scale deployment of my country's 4G network and the upcoming large-scale commercial use, 5G research has gradually entered the field of vision of the industry. Today, small cells are considered to be the core solution for high-capacity hotspot deployments in future networks. Miniaturized, integrated, and energy-efficient small cell design is a necessary condition for low-cost large-scale deployment. RF integrated units for small cell applications will help small cells become ubiquitous. [0003] Currently, the globally recognized 4G technology LTE (including TD-LTE and FDD LTE) has the advantages of high speed and low delay, and can meet the requirements of carrying high-speed data serv...
