Description
Technical field
The present invention relates to wireless communication technology field, more particularly, to a kind of subscriber equipment, base
Stand and correlation technique.
Background technology
Modern mobile radio system presents two distinguishing features, and one is broadband high-speed rate, than
Bandwidth such as forth generation mobile radio system is up to 1Gbps up to 100MHz, downstream rate；
Two is mobile interchange, has promoted the emerging services such as mobile Internet access, mobile video program request, online navigation.
The two feature proposes high requirement to wireless mobile telecommunication technology, mainly has: superelevation speed without
In line transmission, interregional AF panel, movement at transmitting signal, distributed/centralized signal
Reason etc..At following enhancing forth generation (4G) and the 5th generation (5G) mobile radio system
In, in order to meet above-mentioned growth requirement, various corresponding key technologies start to be suggested and prove,
It is worth researcher in this field's extensive concern.
In October, 2007, International Telecommunication Union (ITU) approval worldwide interoperability for microwave accesses system
System (WiMax, Worldwide Interoperability for Microwave Access) becomes the 4th
Individual 3G system standard.This generation is in the event in 3G latter stage in epoch, and actually 4G standard is striven
Take the preview of war by force.It is true that it is wireless in order to tackle with WLAN and WiMax as representative
The challenge of IP technical flow, from the beginning of 2005, third generation 3GPP tissue is just set about carrying out brand-new
System upgrade, the i.e. standardization effort of long evolving system (LTE, Long Term Evolution).
This be one based on orthogonal frequency division multiplexi (OFDM, Orthogonal Frequency Division
Multiplexing) standard four generation system, has released the first edition at the beginning of 2009, and in 2010 years
Commercialization is started successively in the whole world.Meanwhile, 3GPP organizes about forth generation wireless mobile communications
The standardization formulation work of system (4G, the Fourth Generation) is the most in 2008 years
The first half of the year starts, and this system is referred to as advanced long evolving system (LTE-A, Long Term
Evolution Advanced).The key standardisation document of the physical layer procedure of this system is in 2011
The beginning of the year completes.In November, 2011 ITU be organized in Chongqing in China and announce, lte-a system
It is two official standards of 4G system with WiMax system.At present, the commercial mistake of lte-a system
Journey is the most progressively launched.
According to the challenge of following 10 years, for the forth generation mobile radio system strengthened, substantially
There is some growth requirement following:
-higher WiMAX speed, and the hot spot region, community of emphasis optimization local；
-improve Consumer's Experience further, it is accordingly required in particular to optimize the communication service of cell border areas；
-extension of 1000 times can not be had in view of usable spectrum, therefore need to continue research and can carry
The new technique of high spectrum utilization ratio；
The frequency spectrum (5GHz, the highest) of-high band will come into operation, bigger to obtain
Communication bandwidth；
The collaborative work of-existing network (2G/3G/4G, WLAN, WiMax etc.), to share
Data traffic；
-for different business, application and service certain optimisation；
-strengthening system supports the ability of large-scale machines communication；
-flexible, the intelligent and cheap network planning with arrange net；
-design is to save power consumption and the battery consumption of subscriber equipment of network.
In traditional 3GPP LTE system, the most up or downlink transfer is the most permissible
Support the polymerization of 5 component carriers, if each component carrier is 20MHz to the maximum, then subscriber equipment
The maximum transmission that can simultaneously support uplink and downlink 100MHz.For the data stream day by day risen
The demand of amount, the transmission bandwidth of 100MHz has been difficult to meet following demand.3GPP RAN#66
Secondary plenary session discusses a new research topic, the carrier aggregation i.e. strengthened (LTE Carrier
Aggregation Enhancement Beyond 5 Carriers) research (RP-142286), main mesh
Be research support up to 32 component carriers (Component Carrier, CC) up and under
The polymerization technique of row, to improve transfer rate.
Based on this purpose, how system design reports most non-week up to 32 CC if will existing
The problem of phase channel condition information.The User support of Rel-12 is a subframe at present
Report the A-CSI of 5 CC on PUSCH (Uplink Shared Channel) simultaneously.Can give for RAN-1#81 time
The up-to-date working hypothesis gone out is at the number not increasing CSI request territory (CSI Request Field) bit
Under, increase the packet count of CSI aperiodic.
