Shenzhen, China, August 2, 2012]: Huawei, a leading global information and communications technology (ICT) solutions provider, today announced a new proposal for the LTE-Advanced Multi-Stream Aggregation (MSA) technology standard that is capable of increasing data rates at the cell’s edge.
A key component of Huawei’s “No-Edge Networks” concept, MSA technology coordinates macro cells to improve user data rates at the cell’s edge and also between heterogeneous networking scenarios to improve peak rates and simplify mobile management to ensure a consistent user experience.
With the development of mobile broadband, operators are mostly concerned about user experience. With mobile coverage, should able to enjoy the same quality of services no matter where they are. However, with mobile communication systems, the most challenging issue is system performance at the cell’s edge.
The concept behind Huawei’s MSA technology is that the user is always able to receive downlink data and aggregate downlink data streams from a cell or cell group with the best signal quality. A similar method applies to uplink data, where the user always transmits uplink data to a cell or cell group with the best signal quality. The uplink data streams are aggregated on the network side.
Huawei’s MSA technology reduces the number of handovers, lowering device power transmission and increasing device standby time. These advantages are in accordance with the concept of delivering a “borderless network” and “green” wireless communications. It’s expected that MSA technology will improve system performance at the cell’s edge by almost 30%.
MSA technology is especially suitable for macro-micro HetNets. In hotspot area, macro cells provide basic LTE coverage while the micro cells provides capacity enhancement. The use of MSA technology allows users to receive controlled signaling from macro cells and services from best quality HetNet cell. Users at any location within the network can then enjoy fast and stable data services with ultra broadband, zero waiting and ubiquitous connectivity. MSA technology brings users high speeds and high quality as well as a simple service experience.
The advanced MSA technology proposed by Huawei is set to become a key feature of the evolution to 3GPP LTE-Advanced standards. Huawei has contributed 293 core standards to the 3GPP LTE/LTE-Advanced standardization process, 20% of the global total and the most of any other company.
