Bottleneck

UL is the Coverage Bottleneck

• Co-site deployment of C-band with LTE low freq. band

• UL/DL decoupling to eliminate C-band UL coverage

bottleneck.

• Fast introduction of NR with spectrum sharing

instead of refarming to protect LTE investment.

• Promote 5G technologies R&D

• Promote standard consensus on 5G key technologies

5G Technology R&D Trial Launched in China

2016 2017 2020 2015

Step 1: Key tech trial

Step 3: System trial

2018 2019

Phase 1: Technology R&D Trial

Phase 2: Product R&D Trial Step 2: Tech scheme trial

• Single BS performance test to verify the 5G key features

• Multi-cell network verification

Step-2 of 5G Technology R&D Trial

Six leading vendors participation

Huairou, Beijing

Requirements

Common Test/Trial Sites

Common Test Requirement

• Common trial equipment specification and trial platform

• Common trial test specifications and test cases

• Open test interface

Common Test Frequency

• Low Frequency：3.4-3.6GHz (might expand)

• High Frequency：Encourage the system vendor to conduct the

high frequency test, in the absence of allocation of specific trial

high frequency band, the trial can be conducted at indoor lab.
