Far-end unit packet control scheduler in distributed indoor distribution 5G system and scheduling coverage method

Abstract

The invention discloses a far-end unit packet control scheduler in a distributed indoor distribution 5G system and a scheduling coverage method. The control scheduler comprises a packet pilot frequency sending module, a pilot frequency measurement report processing module, a user packet management module and a scheduling module. The scheduling coverage method comprises the following steps: 1, grouping all far-end units in the 5G distributed system; 2, the central unit controls to send pilot signals specific to each far-end unit group on different far-end unit groups; 3, receiving a measurementreport of the user equipment for each pilot signal; 4, specifying a far-end unit group serving the user terminal; 5, allocating wireless resources to the user equipment according to the unit groups serving the user equipment. According to the invention, the problem of bottom noise uplift caused by uplink far-end unit signal combination and the problem of uplink and downlink asymmetry in a traditional 5G indoor distributed system are solved.

Description

technical field [0001] The invention belongs to the field of 5G communication, and specifically refers to a remote unit grouping control scheduler and a scheduling coverage method in a distributed indoor 5G system. Background technique [0002] Distributed small base stations are the main form of equipment for indoor coverage in the 5G era. Due to the high frequency and high penetration loss of 5G, it is difficult to cover indoors through outdoor macro base stations. Only indoor small base stations can provide excellent indoor coverage and throughput. 5G distributed small base stations have become the mainstream indoor coverage solution due to their low cost, good coverage, and strong scalability. A distributed small base station system such as figure 1 As shown, it is composed of the following units, the central unit (Central Unit), the expansion unit (Extended Unit) and the remote unit (Remote Unit). [0003] Among them, the central unit is responsible for the centraliz...
