MIMO Introduction 

MIMO (Multiple Input Multiple output) A set of techniques that rely on the use of multiple antennas at the receiver and/or transmitter. It can be used to achieve improved system capacity and improved coverage area

Single Input Multi Output

Multi Input Multi Output

MIMO

Key Technology-Multi-Antenna Transmission Transmit Diversity

Multiple channels transmit identical information

Diversity Combination

• Include time diversity, space diversity and frequency diversity • Improve receive robustness and expand coverage • Suitable for high reliability or coverage scenarios

Spatial Multiplexing

Multiple channels transmit different information

MMSE or successive interference cancellation

• Theoretically double the peak throughput • Suitable for signal scattered dense urban area, not for direct signal area

Beam-forming

Multiple antennas in beamforming to transmit oneway signal

Maximum ratio combining

• Based on precise channel estimation, beam-forming focus the transmit power in the direction of the target receiver, leading to reduced interference to other radio links and improving the overall signal-to-interference ratio in the system.

Key Technology of CA – Multi-Carrier Joint Scheduling 

In CA mode, multi-carrier scheduling is supported, which can satisfy the requirement from UEs’ high speed data service, besides, resource can be allocated according to the bandwidth of CA cells and

channel condition. As a result, the scheduling efficiency and resource utilization can be improved obviously. F1- Cell

Key Technology of CA – Load Balance

CC2 load

Based on CA scenario: 



Load balance in CA mode supports two flexible options:  Handover for inter-carrier load balance  Joint multi-carrier scheduling between main & sub-carrier based on CA mode It is more flexible for the load adjustment in CA mode to reduce handover frequency and improve the resources utilization and system capacity.

LTE Voice Solution

CSFB Voice in CS Data in LTE SvLTE



SvLTE(Simultaneous voice and LTE): The SvLTE terminal resides in both 2G/3G and LTE network. The legacy CS domain provides voice service

while the LTE network provides data service. Voice and data can occur simultaneously. 

CSFB(circuit switch fallback): As defined in 3GPP R8, the terminal chooses the LTE network to reside by preference and the LTE network provides data service only. When the terminal originates or receives a voice service, it shall fall back to the CS network.



SRVCC(Single Radio Voice Call Continuity): As defined in 3GPP R8, the IMS-based LTE voice service is provided. When the terminal leaves the LTE coverage, the voice service is switched to the CS domain to ensure service continuity. CP

SvLTE •Characteristic: The voice service is provided by the legacy 2G/3G network. •Advantage: A little construction on the network, same user experience, concurrence of data and voice without switchover •Disadvantage: The SvLTE UE has high requirement on chip and battery endurance.

CSFB

•Characteristic: When there is a voice service requirement, the UE falls back to the legacy 2G/3G network.

•Characteristic: The voice service is provided by IMS and voice continuity is ensured during the LTE to 2G/3G handover.

•Advantage: Low requirement on the terminal and reuse of the legacy 2G/3G network.

•Advantage: The LTE-based voice has good tone quality and high spectral efficiency. The concurrency of data and voice service is supported.

•Advantage: The legacy 2G/3G network needs to be reconstructed, the time delay is long, and the concurrency of data and voice is not supported. © ZTE Corporation. All rights reserved
