Description
Technical field
The present invention relates to digital mobile communication technology, more particularly to a kind of 7G carrier aggregation systems and its cross-system measurement
Method.
Background technology
In WCDMA (WCDMA, Wideband Code Division Multiple Access) network, lead to
Include wireless network with land radio access web (UTRAN, Universal Terrestrial Radio Access Network)
Network controller (RNC, Radio Network Controller) and base station (NB, NodeB) two kinds of basic network elements, are commonly called as 3G nets
Network.In Long Term Evolution (LTE, Long Time Evolution) network, evolved universal land radio access web (E-
UTRAN, Enhanced UTRAN) include a kind of basic network element of evolved base station (eNB, eNodeB), it is commonly called as 4G networks.
With the development of WCDMA networks, high-speed downstream receives link packet access (HSDPA, High Speed
Downlink Packet Access), high speed uplink transmission link packet access (HSUPA, High Speed Uplink
Packet Access), dual carrier high-speed slender body theory (DC-HSDPA, Dual Carrier-High speed
Downlink packet access), two-band dual carrier high-speed slender body theory (DB-DC-HSDPA, Dual band-
Dual carrier-high speed downlink packet access), dual carrier high speed uplink packet access (DC-
HSUPA, Dual Carrier-high speed uplink packet access), four carrier wave high-speed slender body theories
(4C-HSDPA, Four carrier-high speed downlink packet access), eight carrier wave high speed downlink packets
Access (8C-HSDPA, Eight carrier-high speed downlink packet access), in these 3G systems
Multi-carrier polymerizing technology is introduced into successively so that UE up-downgoing data transmission rate is continuously available multiplication and improved.For above-mentioned
The multi-carrier polymerizing technology of different dimensions, by taking down direction as an example, an important essential characteristic is：UE must be equipped with a plurality of
Reception data processing chain (3G-Receiver Chain) related 3G, can reception processing simultaneously from same base station, same fan
The 3G data blocks that area (sector), several carrier wave up-downgoings are sent.The WCDMA system for evolving to today is also known as：HSPA+
System (High Speed Packet Access+), is collectively referred to as 3G HSPA+ below.
With the development of LTE network, technology (CA, the Carrier of similar 3G HSPA+ multi-carrier polymerizing concepts
Aggregation) also gradually it is born and realizes, by taking down direction as an example, so far, maximum can be under 5 in LTE system
Carrier wave of the row with a width of 20MHz carries out converging operation, and one important essential characteristic is：It is related that UE must be equipped with a plurality of 4G
Reception data processing chain (4G-Receiver Chain), can simultaneously reception processing from same base station, same sector
(sector), the 4G data blocks that several carrier wave up-downgoings are sent.
Operator by the 3G HSPA+ networks of deployment into the long process of 4G LTE network evolution, be necessarily required to grow very much
For a period of time, two kinds of systems exist and cooperated simultaneously, and shared the downlink and uplink from or towards core-network side
The task of data transfer, such as：There are two carrier frequency points resource F1 and F2 in certain operator, and F1 is distributed into 3G HSPA+ network operations
Use, F2 is distributed into the operation of 4G LTE networks uses.For in its networking, only the terminal of 3G functions can only work on F1
Operation, the only terminal of 4G functions can only work operation on F2, and the terminal for being provided simultaneously with 3G and 4G functions (dual-mode terminal, has
Standby 3G and 4G network service districts data transfer and signal measurement ability), in the fortune that at the same time, can only be worked on F1 or F2
OK, it is impossible to while the operation that worked on F1 and F2.In order to make full use of this kind of bimodulus UE receiving ability, frequency resource is improved
Utilization rate and user equipment downlink peak rate, 7G carrier aggregation technologies (3G+4G) are also known as across HSPA+LTE system carrier aggregation technology
It is born.
The blank framework of 7G technologies discloses at present, and Fig. 1 is the configuration diagram of 7G technologies in the prior art, such as Fig. 1
It is shown, the main control anchor point and data flow-dividing control point of LTE base station eNB as the unique RRC connections of terminal, in down direction
(base station to UE), Physical Downlink Control Channel (PDCCH, Physical Downlinks of the UE on eNB operating carriers
Control Channel) inside traffic order (such as resource allocation, HARQ operation relevant information) control under, from physical down
A part of user data is received in shared channel (PDSCH, Physical Downlink Shared Channel).Meanwhile UE
High-Speed Shared Control Channel (HS-SCCH, High Speed Shared Control on NodeB operating carriers
Channel under traffic order control), from high speed descending sharing channel (HS-DSCH, High Speed-Downlink
Shared Channel) on receive another part user data.Anchor point eNB is responsible for entering the upper layer protocol data bag of itself generation
Row distribution, according to certain mode, determine which part is sent from LTE air interface, which part is sent out from HSPA+ air interface
Send.NodeB protocol data bag is assigned to, it is necessary to be transmitted by new interface between eNB and NodeB, by NodeB according to
The mode of oneself agreement feature and HSPA+ air interfaces is transmitted.If eNB and NodeB are same site (intra-site),
Above-mentioned new interface can be simplified to internal interface.
At up direction (UE to base station), UE will at least be configured on the up frequency for working descending frequency pairing with eNB
Physical Uplink Control Channel (PUCCH, Physical Uplink Control Channel), and control letter is sent on PUCCH
Breath, wherein comprising such as HARQ operation related (be properly received and confirm ACK/NACK), dispatch request, receiving in channel quality instruction
Hold, to feed back the related necessary information of LTE down high-speed datas transmission.Whether UE will work what descending frequency matched in NodeB
High-Speed Dedicated Physical Control Channel (HS-DPCCH, High Speed-Dedicated Physical are sent on up frequency
Control Channel), to feed back the related necessary information of HSPA+ down high-speed datas transmission, in currently studying.It is logical
Often in order to reduce UE uplink transmission power, and reduce uplink interference and the interference of UE internal signals, it is intended to which UE is only empty in LTE
Mouth carries out single system ascending physical signal feedback, rather than ascending physical signal feeds back simultaneously in two systems.
7G multi-carrier polymerizings technology does not occur with carrier aggregation technology each independent in 3G HSPA+ or 4G LTE systems
Conflict, that is to say, that：UE is possible to carry out data receiver on HSPA+M carrier frequency point, and simultaneously can be in LTE N number of load
Data receiver is carried out on wave frequency point.As shown in Fig. 2 network is terminal is configured with two descending carriers on 4G frequencies F1 and F2,
Wherein F1 is downlink main carrier to carry, and corresponding main serving cell Pcell, F2 are descending secondary carrier, corresponding auxiliary serving cell Scell；Together
When network taste terminal be configured with two descending carriers on 3G frequencies F3 and F4.In addition, network may also have some other can use
Frequency resource be available for configuring, depend on the radio signal quality and load on these frequencies.
Because eNB is the main control anchor point that is uniquely connected with RRC, 4G LTE are referred to as master control system, safeguard that a 4G is descending
Main carrier and the descending secondary carriers of several 4G；And 3G HSPA+ systems receive eNB control, claim control system supplemented by 3G HSPA+
System, several 3G descending carriers of maintenance are still descending secondary carrier for whole 7G carrier wave sets.Ideally, eNB,
NB is according to the wireless and resource situation of itself 4G and 3G descending carrier frequency workable for all, such as descending wireless link signals matter
Amount, descending carrier load, there is the terminal of 7G abilities for each, provide optimal 7G carrier combinations configuration.ENB wants rapidly
And such carrier wave set is made in real time and is distributed rationally, it is necessary to measured by wireless environment of the terminal-pair residing for it, and
Wireless measurement result is reported into eNB, so as to be based on these information, eNB makes decisions and reconfigured according to internal algorithm.
In 4G LTE systems, terminal-pair in RRC connected states (RRC_CONNECTED) frequency is outer or the outer carrier wave of 4G systems
When Target cell on face carries out wireless measurement, discontinuous reception (DRX, Discontinuous are generally utilized
Reception) some descending idle periods caused by technology or upper-layer packet dispatching technique (packet scheduling) (DL,
Idle Periods) realize.In 3G HSPA+ systems, terminal-pair in the proprietary states of RRC (Cell_DCH) frequency is outer or 3G
, generally will be by using compact model (CM, Compressed when Target cell on the outer carrier wave face of system carries out wireless measurement
Mode) or some descending idle periods caused by upper-layer packet dispatching technique are realized.Emulation shows：No matter upper-layer packet is passed through
Dispatching Form Headway or compact model form, the business experience of downlink capacity and user to system have bad influence, therefore
More prudent unlatching is needed to use.By taking 3G HSPA+ carrier aggregations as an example, for the relatively good configuration carrier wave set of maintenance optimization,
Terminal needs to perform more frequently frequency external pelivimetry task.The defects of in order to overcome with compressed mode to represent this kind of technology,
The UE of Rel8DC-HSDPA multi-carrier capabilities, its measurement capability (Measurement Capability) may include UE to one
The measurement of descending adjacent secondary carrier can be not turned on ability (the adjacent frequency measurements of compact model
without compressed mode).Similarly, the UE of Rel9DB-HSDPA multi-carrier capabilities, its measurement capability may include
UE can be not turned on the ability (inter-band of compact model to measurement of the descending homologous ray alien frequencies with secondary carrier
frequency measurements without compressed mode).Similarly, Rel104C-HSDPA overloadings wave energy
The UE of power, the measurement that its measurement capability includes same adjacent frequency bands secondary carrier descending to two can be not turned on the ability of compact model
(enhanced inter-frequency measurements without compressed mode)。
When terminal is in 3G carrier aggregation modes of operation, terminal can utilize non-compressed mode measurement in above-mentioned 3G systems
Ability, according to the methods of 3GPP specifications, 3G targets frequency point cell is carried out with the measurement outside frequency range or alien frequencies Duan Pin,
So as to the carrier wave set in the good 3G systems of maintenance optimization, to realize the data transfer of the high quality on high-quality Radio Link.And work as
Terminal using 4G eNB as main control anchor point and when be in 7G carrier aggregation modes of operation, current protocol specification or open skill
Art can not effectively utilize non-compressed mode measurement capability in the above-mentioned 3G systems of terminal, so as to which eNB is existing only by 4G
Some descending idle periods caused by DRX technologies or upper-layer packet dispatching technique measure the target frequency point cell of 3G system sides,
So influence bad in terms of necessarily bringing to the downlink capacity of system and customer service experience.
