Problems solved by technology

The working frequency band of the 5G communication network is relatively high, and the traditional passive indoor DAS (Distributed Antenna System, distributed antenna system) cannot work in this frequency band, and cannot be smoothly upgraded to the corresponding equipment suitable for 5G indoor network coverage
The more complex the bearer function on the pRRU, the higher its cost, and the greater the cost of achieving indoor network coverage

Abstract

The invention provides an active indoor distribution system and a control method and device thereof. In the active indoor distribution system, a centralized processing unit is configured to complete a radio resource control (RRC) layer function and a packet data convergence protocol (PDCP) layer function; the distributed processing unit is configured to complete a radio link control (RLC) layer function, a media access control (MAC) layer function and a physical (PHY) layer function; and the remote radio unit is configured to complete a radio frequency function. According to the invention, indoor network coverage is realized by adopting a three-level architecture, so that the cost is reduced, the performance is improved, further smooth upgrading of equipment in the future is realized, the transmission rate is further improved, the indoor high-speed internet access requirement of people is met, and the landing popularization of 5G is promoted.

Description

technical field [0001] The present disclosure relates to the field of wireless communication, and in particular, to an active room sub-system and a control method and device thereof. Background technique [0002] With the advent of the 5G era, it is an important task for operators to promote full coverage and commercialization of 5G as soon as possible. The 5G communication network operates in a relatively high frequency band, and the traditional passive room distributed DAS (Distributed Antenna System, distributed antenna system) cannot work in this frequency band, and cannot be smoothly upgraded to the corresponding equipment suitable for 5G indoor network coverage. [0003] In addition, in the 5G indoor network, a large number of small pRRUs (Pico Remote Radio Units, remote radio frequency units) need to be used as support to meet the requirements and coverage of high-speed networks, which brings about an increase in cost. The more complex the bearer function on the pRRU...
