Description

Radio communication device and method

Technical field

It is product that modern life can not be one day or scarce that radio communication device, which can be said, there is wireless speech many times daily And data communication supports the operating of the modern life.With the development of science and technology the mankind also get over for the demand of mobile communication bandwidth Come bigger.In the epoch of second generation wireless communication technique, communication bandwidth it is rough fall 100kbps the order of magnitude.March toward the third generation After wireless communication technique, communication bandwidth improves about 100 times, reaches the order of magnitude of 10Mbps.When entrance forth generation channel radio After letter technology, its bandwidth that communicates, which is estimated, again, can reach the series of 1000Mbps or 1Gbps equally into long hundred.

Background technology

In the case where communication bandwidth requirements are so big, no matter using what sample the physical layer communication technology, be required for accounting for With a certain range of wireless communication frequency.Although feasible in theory, in fact, the communication frequency of countries in the world is cut already Cut to miscellaneous communications applications.When the cordless communication network deployment of new generation, so big model is unlikely to find at all The successional wireless communication frequency enclosed is available.In the case where existing occupied frequency can not be removed, just have to Use the technology of referred to as carrier aggregation (carrier aggregation, CA).

Although cannot be communicated using continuous frequency, carrier aggregation function provides different in the multiple wave bands of polymerization carry Ripple is come the ability that communicates.Please refer to Fig.1 shown in A, it is that the frequency comprising different frequency carrier wave is illustrated in multiple wave bands Figure.The transverse axis of Figure 1A -1D represents wireless communication frequency, among these frequencies, includes multiple frequency bands that can be used (band), first band 110 and second band 120 such as shown in Figure 1A.The bandwidth of these wave bands is not necessarily the same, and wave band it Between can be continuous or discontinuous.First band 110 and second band 120 shown in Figure 1A are exactly discontinuous.

Among first band 110, multiple unappropriated carrier frequencies can be included, such as carrier wave A 112 and carrier wave B 114.Carrier wave A 112 and carrier wave B 114 shown in Figure 1A is continuous, and the bandwidth (bandwidth) of carrier wave A 112 can be with It is different with the bandwidth of carrier wave B 114.Such as the bandwidth of the carrier wave B 114 of Figure 1A is greater than the bandwidth of carrier wave A 112.In the second ripple Among section 120, multiple carrier frequencies for utilizing can also be included, such as carrier wave C 122 and carrier wave D 124.Carrier wave C's 122 Bandwidth can be different with the bandwidth of carrier wave D 124, can also be identical.Generally the wireless communication of carrier aggregation function is not supported to fill Put, one can only be selected among this four carrier waves and communicated, and other three carrier waves can not be used.

Please refer to Fig.1 shown in B, it is a frequency diagram of the kenel 1 of carrier aggregation function.Support carrier aggregation function A radio communication device of kenel 1 can be by multiple continuity carrier waves in same first band 110, such as carrier wave A 112 become a communication port with carrier wave B 114, polymerization.The carrier aggregation of this type is referred to as continuous component carrier in wave band It polymerize (intra-band carrier aggregation with continuous component carriers).And by The carrier wave A 112 that condenses together and carrier wave B 114, be referred to as component carrier (component carriers, CCs).

Please refer to Fig.1 shown in C, it is a frequency diagram of the kenel 2 of carrier aggregation function.Support carrier aggregation function A radio communication device of kenel 2 can be by multiple discontinuity carrier waves in same second band 120, such as carrier wave C 122 become a communication port with carrier wave D 124, polymerization.The carrier aggregation of this type is referred to as discontinuous component carrier in wave band Polymerization (intra-band carrier aggregation with non-continuous component carriers).Likewise, be grouped together in carrier wave C 122 together and carrier wave D 124, be referred to as component carrier.

Please refer to Fig.1 shown in D, it is the kenel 3 of carrier aggregation function and a frequency diagram of kenel 4.Wherein, kenel 3 carrier aggregation is located at the carrier wave A 112 and carrier wave B 114 of first band 110, and carrier wave C positioned at second band 120 122.And the carrier aggregation of kenel 4 is located at the carrier wave A 112 and carrier wave B 114 of first band 110, and positioned at second band 120 carrier wave C 122 and carrier wave D 124.The carrier aggregation of both kenels is referred to as the poly- of discontinuous component carrier between wave band Close (inter-band carrier aggregation with non-continuous component carriers).

Among the carrier aggregation example of above-mentioned four kinds of kenels, except the polymerization of continuous component carrier in the wave band of kenel 1 In addition, there is the carrier aggregation of discontinuous component carrier, it is necessary to which multiple transceivers (transceiver) could answer for other three kinds Pay.These transceivers or be radiofrequency signal link (RF chain), refer to the signal line outside Baseband processor.It can wrap Containing component including antenna, mixer, oscillator, amplifier, delay line etc. and combinations thereof.

In the example of the kenel 2 shown in Fig. 1 C, due to carrier wave C 122 and carrier wave D 124 be it is discontinuous, in be spaced Non-carrier frequency.If covering this block cline frequency using single a transceiver, transceiver must spend a large amount of calculating Resource or time make a return journey unless the signal of carrier frequency.In general, all carrier wave C can be received respectively using two transceivers The signal of 122 and carrier wave D 124.

Similarly, among the example of the kenel 3 shown in Fig. 1 D and kenel 4, since component carrier is located at different ripples respectively Section, that is, at least two component carriers be it is discontinuous, in be spaced non-carrier frequency, so to use multiple transceivers To deal with respectively.For example, among the example of form 3, load can be responsible for using the larger transceiver of a processing bandwidth Ripple A 112 and carrier wave B 114, reuses another transceiver to be responsible for carrier wave C 122.Among the example of form 4, except upper Beyond two transceivers for stating kenel 3, the 3rd transceiver is also reused to be responsible for the signal of carrier wave D 124.

Under the situation of kenel 1, can using the larger transceiver of single processing bandwidth come be responsible for carrier wave A 112 with Carrier wave B 114, it is also contemplated that being each responsible for carrier wave A 112 and carrier wave B using two processing less transceivers of bandwidth 114.In general, handling the less transceiver received signal quality of bandwidth can be relatively good.But the drawback is that to take more Remaining volume, cost and the electric power of consumption.

Total described, it is known that among most carrier aggregation kenel, radio communication device must be employed to two Transceiver more than a, could support the function of carrier aggregation.In reality, if radio communication device starts carrier aggregation Function, generally means that radio communication device is carrying out the transmission of high speed.If base station and wireless carrier frequency resource are enough If, radio communication device would generally start all transceivers to carry out the communication of carrier aggregation.However, radio communication device It can move, the base station being in communication with may not can be always maintained at good wireless channel environment.Once enter another When one base station is capable of providing the scope preferably serviced, radio communication device must have the ability to learn the information of another base station, Gone so that signal is switched (handover) by cordless communication network from original base station to another base station so that wireless communication obtains To maintain original bandwidth level or even preferably performance.

However, since radio communication device has supported carrier aggregation to communicate using all transceivers, so that wirelessly Communicator can not call one of transceiver to receive the information of another base station.Therefore, there is an urgent need for meeting to carry as far as possible In the case of ripple polymerizable functional, one of transceiver is called to receive radio communication device and the side of another base station information Method.In addition, the radio communication device for possessing multiple transceivers, even if not supporting carrier aggregation function, equally also needs to call One of transceiver receives the radio communication device and method of another base station information.

It is as follows that the present invention will be described in some embodiments.However, in addition to disclosed embodiment, the present invention can also Other embodiments are widely used in implement.The scope of the present invention is simultaneously not limited to the examples restriction, but with appended Subject to claims.And it is even if that the invention that clearer description those of ordinary skill in the art are understood that the present invention is provided Content, it is illustrated that interior each several part does not have the size opposite according to its and ratio and draws, some sizes and other scale dependents Ratio regular meeting highlighted and the exaggeration that seems, and incoherent detail section is not also drawn completely, in the hope of diagram it is succinct easily Understand.

Shown in please referring to Fig.2, it is the connection according to the radio communication device and a wireless network of the embodiment of the present invention Schematic diagram.The radio communication device 200 has multigroup transceiver and is carried out by an at least first base station 210 with the wireless network Wireless connection.The radio communication device 200 may support carrier aggregation function with the first base station 210, can pass through existing skill The multiple carrier wave for the kenel 1 to 4 that art is mentioned, carries out the wireless communication of carrier aggregation form.In an embodiment of the present invention, the nothing Line communicator 200 can carry out wireless communication by multiple first base stations 210.But among multiple first base stations 210, at least The first base station 210 of an offer main services is provided, is especially to provide control signal.Reason for the purpose of simplifying the description, this hair The bright following first base station 210 that above-mentioned multiple offer wireless services are all provided using first base station 210.

After radio communication device 200 is moved, may enter other base stations radio coverage it It is interior.For example, radio communication device 200 is possibly into interior of building, and the interior of building can be equiped with one second Base station 220.Second base station 220 can be femto cell (pico-cell) or milli femto cell (femto-cell), specially use In the wireless access capability for providing the interior of building.In another example, radio communication device 200 can move into closer The place of one the 3rd base station 230.Among the two examples, since distance is near compared with first base station 210, the second base station 220 and the Three base station 230 may can provide radio communication device 200 more preferable service quality.

In one embodiment, above-mentioned radio communication device 200 can be meet Long Term Evolution advanced versions (LTE-A, Long Term Evolution-Advanced) technology radio communication device 200.Above-mentioned first base station 210 can also be Meet the base station of Long Term Evolution advanced versions technology, be referred to as evolution B node (eNodeB, Evolved Node B).Above-mentioned Second base station 220 can be the base station from home for meeting Long Term Evolution advanced versions technology, be referred to as family expenses evolution B node (Home eNodeB).The 3rd above-mentioned base station 230 can be evolution B node or meet the base station of other wireless technology standards, Such as CDMA2000, W-CDMA, TD-S-CDMA standard of CDMA access technology.Those of ordinary skill in the art can be with Understand, implementation example provided by the present invention can be adapted for Long Term Evolution advanced versions technology, because the technical support carrier wave Polymerizable functional.And the present invention is not limited to Long Term Evolution advanced versions technology, as long as any have the wireless of multigroup transceiver Access device, can use apparatus and method provided by the present invention.

Above-mentioned wireless network can include multiple base stations, to provide the covering model of 200 wireless access of radio communication device Enclose.Among actual wireless deployment scenario, the quantity of the second base station 220 of smaller area or room area is only covered, can Can be far more than the quantity of the first base station 210 of covering large area.The particularly design feature of the second base station 220, is terminal User rapidly voluntarily can dispose and set, and even wireless network dealer (operator) may not know the second base yet The place for 220 actual deployments of standing, therefore may not be included in the wireless network blueprint of wireless network dealer numerous And the second base station 220 per diurnal variation.But, if radio communication device 200 want enjoy the second base station 220 provided it is preferable The information of second base station 220 just must be transmitted to network by service, radio communication device 200 by first base station 210.

In addition, a wireless network dealer may only operate the wireless network of a certain standard technique.Such as dealer's first 210 and second base station 220 of wireless network connection first base station, and dealer's second is connected using the wireless network of another standard technique Connect the 3rd base station 230.For dealer's first, the 3rd base station 230 is also not included in its wireless network blueprint.But for nothing For line communicator 200, if its setting can carry out roaming intercommunication, wireless communication dress between dealer's first and dealer's second If putting 200 to want to enjoy the preferable service that the 3rd base station 230 is provided, radio communication device 200 just must be by the 3rd base station 230 Information, the wireless network of dealer's first and/or dealer's second is transmitted to by first base station 210.

In one embodiment, radio communication device 200 is after movement, it is necessary to the first base station information (example arround detection Such as the wireless identification message of base station) or measurement arround base station signal.The radio detection of the base station to arround can divide with measurement For two kinds of forms.One kind is common frequency measurement (intra-frequency measurement), wherein base station to be measured (such as second 220 or the 3rd base station 230 of base station) operated with first base station 210 in identical carrier frequency.It is another then be different-frequency measure (inter-frequency measurement), wherein base station to be measured is operated in different carrier frequencies from first base station 210 On.

It is, in general, that when radio communication device 200 carries out wireless communication with first base station 210, it is different in order to complete Frequency measures, and first base station 210 can indicate there is which or measurement gap in communication by wireless control signal free time (measurement gap), radio communication device 200 can be in the base station informations arround these free times or gap detection Base station signal arround (such as entity cell identification message) or measurement.In the present embodiment, if first base station 210 knows nothing The transceiver configuration configuration of line communicator 200, it is possible to specify channel radio using apparatus and method provided by the present invention T unit 200 is measured using which transceiver.In addition, first base station 210 may also be without specified free time or measurement Gap allows radio communication device 200 to carry out different-frequency measure.In this embodiment, radio communication device 200 can be used independently Apparatus and method provided by the present invention determine to be measured using which transceiver.

In another embodiment, when signal measurement result shows the second base station 220 or the arround radio communication device 200 Three base stations, 230 signal quality is fine, first base station 210 may need further to know arround the second base station 220 or the 3rd The other information (such as cell tautology identification message) of base station 230, to carry out base station switching (hand-over or hand- off).However, first base station 210 may allow radio communication device 200 to detect without offer free time or specified measurement gap Second base station 220 or the system information (system information) of the 3rd base station 230.In the present embodiment, if had The radio communication device 200 of multigroup transceiver was also wanted in first base station 210 without offer free time or specified measurement gap In the case of the base station to arround measure, must just use apparatus and method provided by the present invention.Further, since the second base Stand 220 or the 3rd the system information of base station 230 can only put appearance at a fixed time, even if network has specified measurement gap, nothing Line communicator 200 is it is also possible that the second base station 220 or the 3rd base station 230 can not be detected in specified measurement gap is System information.In the present embodiment, in the case that first base station 210 is provided with free time or specified measurement gap, channel radio T unit 200 still can use apparatus and method provided by the present invention.

It is, in general, that when the wireless signal of base station arround radio communication device 200 measures, usually can be by wireless The message that signal includes is come the identification signal of base station (such as the second base station 220 or the 3rd base station 230) arround knowing.By transmission Arround base station identification signal, the wireless network that radio communication device 200 is connected can be by communication line from original One base station 210 is switched to the second base station 220 or the 3rd base station 230.Switch (hand-over or hand-off) program in base station Afterwards, the main services base station of radio communication device 200 is just switched to the second base station 220 or the from original first base station 210 Three base stations 230.In addition, first base station 210 and the second base station 220 or the 3rd base station 230 may use it is identical or different wireless Access technology (radio access technology, RAT).If 210 and second base station 220 of first base station or the 3rd base station 230 using identical wireless access technology when, switching behavior at this time switches between being called same wireless access technology (Intra-RAT handover).If first base station 210 and the second base station 220 or the 3rd base station 230 use different wireless During access technology, switching behavior at this time is called switching (Inter-RAT handover) between different wireless access technology.

In an embodiment of the present invention, since the quantity of femto cell or family expenses evolution B node (Home eNodeB) is huge Greatly, therefore in wireless signal it is used to identify that the wireless identification message of the second base station 220 may repeat.Even if wireless communication fills Put the 200 wireless identification messages for measuring the second base station 220, network be also unknown to by communication line be switched to which second Base station 220.For example, among 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 there was only 512 kinds of different entity cell identification news altogether Breath.If the place that first base station 210 is set up is among highdensity metropolitan area, can in several kilometers of radio covering radius There can be thousands of family households, also just there are thousands of a femto cell or family expenses evolution B nodes.In other words multiple base stations may Use identical entity cell identification message, particularly femto cell or family expenses evolution B node.In another embodiment of the present invention In, the wireless identification message using the 3rd base station 230 of another wireless technology is probably what wireless network was failed to understand.

If wireless network can not be recognized wireless by the wireless identification message of such as class of entity cell identification message Base station arround communicator 200, then wireless network may require radio communication device 200 within the regular hour, return Arround base station tautology identification message.Tautology identification message referred herein, is to be exclusively used in representing the base station.For example, long-term Among evolution advanced versions technology, first base station 210 can assign radio communication device 200 report cell tautology identification message Instruct (reportCGI), make radio communication device 200 returned within a period of time arround base station cell tautology identification message (CGI, Cell Global Identity).Since tautology identification message can be exclusively used in representing the base station, this is generally contained within Among the system information (System Information) of base station broadcast.It is different with foregoing wireless identification message, wireless communication Device 200 must carry out the reception and decoding of long period, just have method to parse tautology identification message.This section is used to receive and solve The off time of code is decided in its sole discretion by radio communication device 200, and first base station 210 can't inform radio communication device 200 When carry out receiving tautology identification message.Therefore, this section of off time is referred to as independence gap (autonomous gap), by 200 independence of radio communication device judges which section time can be evacuated to receive the tautology identification message of base station near parsing, and And network is arrived by the return of first base station 210.

Total described, either measurement gap or independence gap are filled as long as there is the wireless communication of multigroup transceiver 200 are put using internal at least one transceiver to receive the information of neighbouring base station, includes radio signal strength, wireless identification Message and/or tautology identification message, may be by apparatus and method provided by the present invention.

Each transceiver 310 has the property for being applicable in wave band and wave band bandwidth.For example, Long Term Evolution (LTE, Long Term Evolution) among technology, the carrier wave bandwidth in the same band can be 1.4,3,5,10,15 or 20MHz. Therefore, can only handle smaller frequency suitable for the transceiver 310 of Long Term Evolution or Long Term Evolution advanced versions technology Wide transceiver or the transceiver of larger bandwidth can be handled.Support the radio communication device 200 of carrier aggregation function A transceiver 310 may be included, the wherein processing bandwidth of transceiver 310 is greater than or equal to 20MHz.At this time, the institute of transceiver 310 The carrier aggregation kenel that can be dealt with may be only limited to the polymerization (intra-band of continuous component carrier in 1 wave band of kenel carrier aggregation with continuous component carriers).But if support carrier aggregation work( The radio communication device 200 of energy includes multiple transceivers 310, wherein the processing frequency of each transceiver 310-1,310-2,310-N Width is less than 20MHz, then the transceiver 310 is except that can deal with 1 wave band of kenel in addition to the polymerization of continuous component carrier, moreover it is possible to should State of making paper moulds 2, polymerization (the intra-band carrier aggregation with non-of discontinuous component carrier in wave band Continuous component carriers), and kenel 3 and kenel 4, the polymerization of discontinuous component carrier between wave band (inter-band carrier aggregation with non-continuous component carriers)。

It will be understood by those skilled in the art that arriving, multiple transceivers 310 in radio communication device 200 can be Identical kenel or different forms.They can be covered each by identical wave band, can also cover different ripples Section.They can have identical processing bandwidth, it is possible to have different processing bandwidths.The quantity and property of transceiver 310 End relies in miscellaneous application to determine, the present invention does not limit the number of multiple transceivers 310 in radio communication device 200 Amount and property.
