Description

Radio communication device and method

Technical field

Radio communication device can say that modern lives can not one day or scarce product, has every day wireless speech many times and data communication supporting the running of the modern life.Along with scientific and technological progress, the mankind are also increasing for the demand of mobile communication frequency range.In the epoch of second generation wireless communication technology, the rough order of magnitude that drops on 100kbps of communication frequency range.After marching toward third generation wireless communication technology, communication frequency range has improved approximately 100 times, reaches the order of magnitude of 10Mbps.After entering the 4th generation wireless communication technology, its communication frequency range is estimated and will be become equally long hundred doubly, can reach the progression of 1000Mbps or 1Gbps.

Background technology

In the situation that communication frequency range demand is so large, no matter use the physical layer communication technology of what sample, all need to take the wireless communication frequency of certain limit.Although feasible in theory, in fact, the communication frequency of countries in the world is cut already to communications applications miscellaneous.When new cordless communication network is from generation to generation disposed, may not find so large-scale successional wireless communication frequency available.In the case of removing existing occupied frequency, just must use the technology that is called carrier aggregation (carrier aggregation, CA).

Although can not use continuous frequency to communicate, carrier aggregation function provides the ability that in the multiple wave bands of polymerization, different carrier communicates.Please refer to shown in Figure 1A its frequency diagram for comprising different frequency carrier wave in multiple wave bands.The transverse axis of Fig. 1 represents wireless communication frequency, in the middle of these frequencies, comprises multiple operable frequency bands (band), for example the first wave band 110 shown in Figure 1A and the second wave band 120.The frequency range of these wave bands may not be identical, and between wave band, can be continuously, can be also discontinuous.The first wave band 110 shown in Figure 1A and the second wave band 120 are exactly discontinuous.

In the middle of the first wave band 110, can comprise multiple unappropriated carrier frequencies, as carrier wave A112 and carrier wave B114.Carrier wave A112 shown in Figure 1A and carrier wave B114 are continuous, and the frequency range of carrier wave A112 (bandwidth) can be different with the frequency range of carrier wave B114.The frequency range of the carrier wave B114 of for example Figure 1A is just greater than the frequency range of carrier wave A112.In the middle of the second wave band 120, also can comprise multiple carrier frequencies for utilizing, as carrier wave C122 and carrier wave D124.The frequency range of carrier wave C122 can be different with the frequency range of carrier wave D124, also can be identical.The general radio communication device of not supporting carrier aggregation function can only be selected one to communicate, and cannot use other three carrier waves in the middle of these four carrier waves.

Please refer to shown in Figure 1B, it is a frequency diagram of the kenel 1 of carrier aggregation function.Support a radio communication device of the kenel 1 of carrier aggregation function will be positioned at multiple continuity carrier waves of same the first wave band 110, as carrier wave A112 and carrier wave B114, polymerization becomes a communication port.What the carrier aggregation of this type claimed is the polymerization (intra-band carrier aggregation with continuous component carriers) of component carrier continuously in wave band.And be grouped together in carrier wave A112 and carrier wave B114 together, title be component carrier (component carriers, CCs).

Please refer to shown in Fig. 1 C, it is a frequency diagram of the kenel 2 of carrier aggregation function.Support a radio communication device of the kenel 2 of carrier aggregation function will be positioned at multiple discontinuity carrier waves of same the second wave band 120, as carrier wave C122 and carrier wave D124, polymerization becomes a communication port.The polymerization (intra-band carrier aggregation with non-continuous component carriers) for discontinuous component carrier in wave band that the carrier aggregation of this type claims.Same, be grouped together in carrier wave C122 and carrier wave D124 together, title be component carrier.

Please refer to shown in Fig. 1 D, it is the kenel 3 of carrier aggregation function and a frequency diagram of kenel 4.Wherein, the carrier aggregation of kenel 3 be positioned at carrier wave A112 and the carrier wave B114 of the first wave band 110, and be positioned at the carrier wave C122 of the second wave band 120.And the carrier aggregation of kenel 4 be positioned at carrier wave A112 and the carrier wave B114 of the first wave band 110, and be positioned at carrier wave C122 and the carrier wave D124 of the second wave band 120.The polymerization (inter-band carrier aggregation with non-continuous component carriers) for discontinuous component carrier between wave band that the carrier aggregation of these two kinds of kenels claims.

In the middle of the carrier aggregation example of above-mentioned four kinds of kenels, in the wave band of kenel 1, the polymerization of continuous component carrier, other three kinds have the carrier aggregation of discontinuous component carrier, need multiple transponders (transceiver) just can deal with.These transponders or be called radiofrequency signal link (RF chain), the signal line outside general reference fundamental frequency processor.Can comprise antenna, blender, oscillator, amplifier, delay line in interior etc. parts and combination thereof.

In the example of the kenel 2 shown in Fig. 1 C, because carrier wave C122 and carrier wave D124 are discontinuous, middle interval non-year wave frequency.If cover this piece cline frequency with single transponder, unless transponder must spend the make a return journey signal of carrier frequency of a large amount of computational resources or time.In general, all can use two transponders to distinguish the signal of reception carrier C122 and carrier wave D124.

In like manner, in the middle of the example of the kenel 3 shown in Fig. 1 D and kenel 4, because component carrier lays respectively at different wave bands, that is to have two component carriers at least be discontinuous, middle interval non-year wave frequency, so deal with respectively with multiple transponders.For example, in the middle of the example of form 3, can process the larger transponder of frequency range with one and be responsible for carrier wave A112 and carrier wave B114, re-use another transponder and be responsible for carrier wave C122.In the middle of the example of form 4, except two transponders of above-mentioned kenel 3, also to re-use the 3rd transponder and be responsible for the signal of carrier wave D124.

Under the situation of kenel 1, can process the larger transponder of frequency range with single and be responsible for carrier wave A112 and carrier wave B114, also can consider that processing the less transponder of frequency range with two is responsible for respectively carrier wave A112 and carrier wave B114.In general the signal quality that, the less transponder of processing frequency range receives can be relatively good.But its shortcoming is the electric power that will take unnecessary volume, cost and consume.

Always the above, can know that radio communication device must be employed plural transponder in the middle of most carrier aggregation kenel, could support the function of carrier aggregation.In reality, if radio communication device has started the function of carrier aggregation, conventionally mean that radio communication device is carrying out transmission at a high speed.If base station and wireless carrier frequency resource are enough, radio communication device conventionally can start all transponders and carry out the communication of carrier aggregation.But radio communication device is can be mobile, the base station communicating with it may not keep good wireless channel environment always.Can provide the scope of better service once enter into another base station, radio communication device must have the ability to learn the information of another base station, go to another base station so that cordless communication network switches (handover) by signal from original base station, make radio communication be maintained original frequency range level or or even better performance.

But, because having used all transponder, radio communication device supports carrier aggregation communication, to such an extent as to cannot calling one of them transponder, radio communication device receives the information of another base station.Therefore, need badly in the situation that meeting carrier aggregation function as far as possible, call one of them transponder and receive radio communication device and the method for another base station information.In addition,, for the radio communication device that has multiple transponders, even if do not support carrier aggregation function, equally also need to call one of them transponder and receive radio communication device and the method for another base station information.

It is as follows that the present invention will describe some embodiment in detail.But except disclosed embodiment, the embodiment that the present invention can also be used in other widely implements.Scope of the present invention is not subject to the restriction of these embodiment, but is as the criterion with appending claims.Even and for providing clearer description those of ordinary skill in the art can understand summary of the invention of the present invention, each several part in diagram is not drawn according to its relative size and ratio, some size is highlighted and the exaggeration that seems with the ratio regular meeting of other scale dependents, and incoherent detail section is not also drawn completely, in the hope of illustrated succinctly understandable.

Please refer to shown in Fig. 2, it is according to the connection diagram of a radio communication device of the embodiment of the present invention and a wireless network.This radio communication device 200 has many group transponders and carries out wireless connections by least one the first base station 210 with this wireless network.This radio communication device 200 may be supported carrier aggregation function with this first base station 210, and the multiple carrier wave of the kenel 1 to 4 that can mention by prior art carries out the radio communication of carrier aggregation form.In an embodiment of the present invention, this radio communication device 200 can carry out radio communication by multiple the first base stations 210.But in the middle of multiple the first base stations 210, at least have first base station 210 that main services is provided, control signal is particularly provided.Cause for the purpose of simplifying the description, the present invention all replaces above-mentioned multiple the first base station 210 that wireless service is provided with the first base station 210 below.

After radio communication device 200 moves, within may entering into the radio coverage of other base stations.For example, radio communication device 200 may enter into interior of building, and this interior of building can be equiped with one second base station 220.This second base station 220 can be femto cell (pico-cell) or milli femto cell (femto-cell), is specifically designed to the wireless access capability that this interior of building is provided.In another example, radio communication device 200 may move to the place near one the 3rd base station 230.In the middle of these two examples, because distance is near compared with the first base station 210, the second base station 220 and the 3rd base station 230 may can provide radio communication device 200 better service quality.

In one embodiment, above-mentioned radio communication device 200 can be the radio communication device 200 that meets Long Term Evolution advanced versions (LTE-A, Long Term Evolution-Advanced) technology.The first above-mentioned base station 210 can be also the base station that meets Long Term Evolution advanced versions technology, is referred to as evolution B node (eNodeB, Evolved Node B).The second above-mentioned base station 220 can be the base station from home that meets Long Term Evolution advanced versions technology, is referred to as family expenses evolution B node (Home eNodeB).The 3rd above-mentioned base station 230 can be evolution B node, can be also the base station that meets other wireless technology standards, for example CDMA2000 of code division multiple access access technology, W-CDMA, TD-S-CDMA standard.Those of ordinary skill in the art can understand, enforcement example provided by the present invention goes for Long Term Evolution advanced versions technology, because this technical support carrier aggregation function.And the present invention is not limited to Long Term Evolution advanced versions technology, as long as any wireless access device with many group transponders, can use apparatus and method provided by the present invention.

Above-mentioned wireless network can comprise multiple base stations, so that the coverage of radio communication device 200 wireless access to be provided.In the middle of the wireless deployment scenario of reality, only cover compared with the quantity of the second base station 220 of zonule or room area, may be far more than the quantity of first base station 210 in the larger region of covering.The particularly design feature of the second base station 220, be that terminal user can dispose voluntarily rapidly and set, wireless network dealer (operator) may not know the place of the second base station 220 actual deployment yet even, therefore in wireless network dealer's wireless network blueprint, may not can comprise the second base station 220 of numerous and every diurnal variation.But, if radio communication device 200 wants to enjoy the better service that the second base station 220 provides, radio communication device 200 just must, by the information of the second base station 220, be passed to network by the first base station 210.

In addition, wireless network dealer may only operate the wireless network of a certain standard technique.The for example wireless network of dealer's first connects the first base station 210 and the second base station 220, and dealer's second adopts the wireless network of another kind of standard technique to connect the 3rd base station 230.Concerning dealer's first, the 3rd base station 230 is not included in its wireless network blueprint yet.But for radio communication device 200, if its setting can be roamed intercommunication between dealer's first and dealer's second, if radio communication device 200 wants to enjoy the better service that the 3rd base station 230 provides, radio communication device 200 just must, by the information of the 3rd base station 230, be passed to the wireless network of dealer's first and/or dealer's second by the first base station 210.

In one embodiment, radio communication device 200 after movement, the base station information (the wireless identification message of for example base station) arround must first detecting or measure arround base station signal.To arround base station radio detection with measure can be divided into two kinds of forms.One is common frequency measurement (intra-frequency measurement), and wherein base station to be measured (for example the second base station 220 or the 3rd base station 230) operates in identical carrier frequency with the first base station 210.Another kind is different-frequency measure (inter-frequency measurement), and wherein base station to be measured operates in different carrier frequencies from the first base station 210.

In general, in the time that radio communication device 200 carries out radio communication with the first base station 210, in order to complete different-frequency measure, the first base station 210 can indicate and be had which free time or measurement clearance (measurement gap) when the communication by wireless control signal, the base station signal that radio communication device 200 just can for example, arround the base station information arround these free times or gap detection (entity cell identification message) or measurement.In the present embodiment, if the transponder configuration configuration of radio communication device 200 is known in the first base station 210, just can carry out specific radio communicator 200 by apparatus and method provided by the present invention and use which transponder to measure.In addition, the first base station 210 also may not specify free time or measurement clearance to allow radio communication device 200 carry out different-frequency measure.In this embodiment, radio communication device 200 can independently use apparatus and method provided by the present invention to decide which transponder of use to measure.

In another embodiment, the second base station 220 arround signal measurement result display radio communicator 200 or the 3rd base station 230 signal qualities are fine, the second base station 220 arround the first base station 210 may need further to know or the out of Memory of the 3rd base station 230 (for example community universe identification message), to carry out base station switching (hand-over or hand-off).But the first base station 210 may not provide free time or specified measurement gap to allow radio communication device 200 detect the system information (system information) of the second base station 220 or the 3rd base station 230.In the present embodiment, if the in the situation that of thering are the radio communication devices 200 of many group transponders and also want not provide free time or specified measurement gap in the first base station 210 to arround base station measure, just must use apparatus and method provided by the present invention.In addition, because the system information of the second base station 220 or the 3rd base station 230 only can be put appearance at a fixed time, even if network has specified measurement gap, radio communication device 200 still likely cannot detect the system information of the second base station 220 or the 3rd base station 230 in the measurement clearance of specifying.In the present embodiment, when the first base station 210 has in the situation that free time or specified measurement gap are provided, radio communication device 200 still can use apparatus and method provided by the present invention.

In general, arround radio communication device 200 measures when the wireless signal of base station, the message that conventionally can include by wireless signal know arround the identification signal of base station (for example the second base station 220 or the 3rd base station 230).By the identification signal of base station arround transmitting, the wireless network that radio communication device 200 connects just can be switched to the second base station 220 or the 3rd base station 230 from the first original base station 210 by communication line.After (hand-over or hand-off) program is switched in base station, the main services base station of radio communication device 200 is just switched to the second base station 220 or the 3rd base station 230 from the first original base station 210.In addition, the first base station 210 and the second base station 220 or the 3rd base station 230 may be used identical or different wireless access technology (radio access technology, RAT).If when the first base station 210 is used identical wireless access technology with the second base station 220 or the 3rd base station 230, switching behavior is now called switching (Intra-RAT handover) between same wireless access technology.If when the first base station 210 is used different wireless access technologys from the second base station 220 or the 3rd base station 230, switching behavior is now called switching (Inter-RAT handover) between different wireless access technology.

In an embodiment of the present invention, because the quantity of femto cell or family expenses evolution B node (Home eNodeB) is huge, therefore in wireless signal, may repeat for the wireless identification message of identifying the second base station 220.Even if radio communication device 200 measures the wireless identification message of the second base station 220, network does not know communication line to be switched to which the second base station 220 yet.For example,, in the middle of Long Term Evolution advanced versions technology, the wireless identification message of each base station is referred to as entity cell identification message (PCI, Physical Cell Identity), and altogether only has 512 kinds of different entity cell identification messages.If, in the middle of highdensity metropolitan area, may there be thousands of family households in the place that set up the first base station 210 in several kilometers of radio covering radiuss, also just there are thousands of femto cell or family expenses evolution B node.In other words multiple base stations may be used identical entity cell identification message, particularly femto cell or family expenses evolution B node.In another embodiment, using the wireless identification message of the 3rd base station 230 of another kind of wireless technology may be that wireless network is failed to understand.

If wireless network cannot be by recognizing the base station arround radio communication device 200 as the wireless identification message of the class of entity cell identification message, wireless network may require radio communication device 200 within the regular hour so, the universe of base station identification message arround return.Here the universe of indication identification message is to be exclusively used in to represent this base station.For example, in the middle of Long Term Evolution advanced versions technology, reporting cell universe identification message instruction (reportCGI) can be assigned to radio communication device 200 in the first base station 210, make radio communication device 200 within a period of time, return arround the community universe identification message (CGI, Cell Global Identity) of base station.Represent this base station because universe identification message can be exclusively used in, be conventionally contained in the middle of the system information (System Information) of this base station broadcast.Different with aforesaid wireless identification message, radio communication device 200 must carry out reception and the decoding of long period, just has way to parse universe identification message.This section is to be decided in its sole discretion by radio communication device 200 for receiving with the off time of decoding, and the first base station 210 can't inform when radio communication device 200 receives universe identification message.Therefore, be called as independence gap (autonomous gap) this period of off time, by radio communication device 200 independences judge which section period can find time to receive resolve near the universe identification message of base station, and by the first base station 210 return to network.

Total the above, no matter be measurement clearance or independence gap, utilize at least one inner transponder to receive near the information of base station as long as there is the radio communication device 200 of many group transponders, comprise radio signal strength, wireless identification message and/or universe identification message, can utilize apparatus and method provided by the present invention.

Please refer to shown in Fig. 3, it is a block schematic diagram of a radio communication device 200 according to an embodiment of the invention.Support the radio communication device 200 of carrier aggregation function may comprise multiple transponders 310 (such as, transponder 310-1,310-2 ... 310-N).According to the present invention, radio communication device 200 can be used in two transponders of supporting above carrier aggregation function.

Each transponder 310 has the character that is suitable for wave band and wave band frequency range.For example,, in the middle of Long Term Evolution (LTE, Long Term Evolution) technology, the carrier wave frequency range in the same band can be 1.4,3,5,10,15 or 20MHz.Therefore, being applicable to the transponder 310 of Long Term Evolution or Long Term Evolution advanced versions technology, can be the transponder that can only process less frequency range, can be also the transponder that can process larger frequency range.Support the radio communication device 200 of carrier aggregation function may comprise a transponder 310, wherein the processing frequency range of transponder 310 is more than or equal to 20MHz.Now, the carrier aggregation kenel that 310 of transponders can be dealt with may be only limited to the polymerization (intra-band carrier aggregation with continuous component carriers) of component carrier continuously in kenel 1 wave band.If but support the radio communication device 200 of carrier aggregation function to comprise multiple transponders 310, wherein each transponder 310-1, 310-2, the processing frequency range of 310-N is less than 20MHz, so the polymerization of this transponder 310 continuous component carrier in can dealing with kenel 1 wave band, can also deal with kenel 2, the polymerization (intra-band carrier aggregation with non-continuous component carriers) of discontinuous component carrier in wave band, and kenel 3 and kenel 4, the polymerization of discontinuous component carrier between wave band (inter-band carrier aggregation with non-continuous component carriers).

Those having ordinary skill in the art will appreciate that, the multiple transponders 310 in radio communication device 200 can be identical kenels, can be also different forms.They can cover respectively identical wave band, also can cover different wave bands.They can have identical processing frequency range, also can have different processing frequency ranges.The quantity of transponder 310 and character end rely in application miscellaneous and decide, and the present invention does not limit quantity and the character of the multiple transponders 310 in radio communication device 200.

Radio communication device 200 more comprises a communication module 320, for being connected to above-mentioned multiple transponders 310, for communicating after 310 corresponding multiple component carrier polymerizations of the plurality of transponder.For example, in a certain version of Long Term Evolution advanced technology, specify, when radio communication device 200 carries out carrier aggregation, at most can five component carriers of polymerization.In other words, meet the radio communication device 200 of Long Term Evolution advanced technology specification, may there are five corresponding five component carriers of transponder 310 simultaneously.

Radio communication device 200 also comprises a processing module 330, for in the time using the plurality of transponder 310 to communicate simultaneously, in the middle of the plurality of transponder 310, select one first transponder 310-1, make this transponder stop being connected to this first base station 210, and start to receive the information of this second base station 220 and/or the 3rd base station 230.Wherein the packets of information of this second base station 220 and/or the 3rd base station 230 is containing wireless identification message and/or universe identification message.Each following embodiment is for explanation, how in the middle of multiple transponders 310, select at least one the first transponder 310-1 receive arround the message of base station.When radio communication device 200 need to open multiple measurement clearance or independence gap come to arround base station measurement radio signal strength or detect wireless identification message and/or when universe identification message, also can utilize apparatus and method provided by the present invention.In another embodiment, radio communication device 200 also may only carry out radio communication by the first transponder 310-1 in multiple transponders 310 and the first base station 210, and the second transponder 310-2 and the 3rd transponder 310-3 be the designated signal strength signal intensity that is used for respectively measuring the second base station 220 and the 3rd base station 230.Now, if network terminal requires wireless communication apparatus to receive the community universe identification message of another base station (not shown), utilize the method for this patent, also can from the second transponder 310-2 and the 3rd transponder 310-3, choose a best transponder and receive the community universe identification message of another base station.

In one embodiment of this invention, this processing module 330 can be carried out one first and select step, this the first selection step comprises selects one second central transponder 310-2 of the plurality of transponder 310, and make this second transponder 310-2 more be connected to this first base station 210 by the corresponding component carrier of this first transponder 310-1 institute, wherein the corresponding component carrier of this second transponder 310-2 institute and this first transponder 310A accordingly component carrier belong to the continuous carrier of the same band.

In one embodiment of this invention, communication module 320 can be embodied on same chip with processing module 330, or is embodied in the middle of a radio communication device.This chip or radio communication device are for connecting above-mentioned multiple transponders 310.Whether the present invention does not limit the implementation mode of above-mentioned transponder 310, communication module 320 and processing module 330, do not limit it yet and be embodied in the middle of same chip.
