Description

Wireless communication device and method

technical field

Wireless communication devices can be said to be an indispensable product of modern life. There are countless wireless voice and data communications every day to support the operation of modern life. With the advancement of technology, human beings have an increasing demand for mobile communication bandwidth. In the era of the second-generation wireless communication technology, the communication bandwidth is roughly on the order of 100kbps. After entering the third generation of wireless communication technology, the communication bandwidth has been improved by about one hundred times, reaching the order of magnitude of 10Mbps. After entering the fourth generation of wireless communication technology, its communication bandwidth is expected to grow a hundredfold, reaching 1000Mbps or 1Gbps.

Background technique

In the case of such a large demand for communication bandwidth, no matter what kind of physical layer communication technology is used, it needs to occupy a certain range of wireless communication frequencies. Although it is feasible in theory, in fact, the communication frequencies of countries all over the world have already been divided into various communication applications. When the new generation of wireless communication networks are deployed, it is impossible to find such a wide range of continuous wireless communication frequencies available. If the existing occupied frequency cannot be removed, a technique called carrier aggregation (CA) must be used.

Although it is not possible to use contiguous frequencies for communication, the carrier aggregation function provides the ability to aggregate different carriers in multiple bands for communication. Please refer to FIG. 1A , which is a frequency schematic diagram including different frequency carriers in multiple bands. The horizontal axis of FIGS. 1A-1D represents wireless communication frequencies, among which there are multiple usable frequency bands, such as the first band 110 and the second band 120 shown in FIG. 1A . The bandwidths of these bands are not necessarily the same, and the bands can be continuous or discontinuous. The first wave band 110 and the second wave band 120 shown in FIG. 1A are discontinuous.

In the first band 110 , there may be a plurality of unoccupied carrier frequencies, such as carrier A 112 and carrier B 114 . Carrier A 112 and carrier B 114 shown in FIG. 1A are contiguous, and the bandwidth of carrier A 112 may be different from that of carrier B 114 . For example, the bandwidth of carrier B 114 in FIG. 1A is greater than the bandwidth of carrier A 112 . The second band 120 may also include multiple available carrier frequencies, such as carrier C 122 and carrier D 124 . The bandwidth of carrier C 122 may be different from that of carrier D 124, or may be the same. Generally, a wireless communication device that does not support the carrier aggregation function can only select one of the four carriers for communication, and cannot use the other three carriers.

Please refer to FIG. 1B , which is a frequency schematic diagram of type 1 of the carrier aggregation function. A type 1 wireless communication device supporting the carrier aggregation function can aggregate multiple consecutive carriers located in the same first band 110 , such as carrier A 112 and carrier B 114 , into a communication channel. This type of carrier aggregation is called intra-band carrier aggregation with continuous component carriers. The aggregated carrier A 112 and carrier B 114 are called component carriers (CCs).

Please refer to FIG. 1C , which is a frequency schematic diagram of type 2 of the carrier aggregation function. A type 2 wireless communication device supporting the carrier aggregation function can aggregate a plurality of discontinuous carriers located in the same second band 120 , such as carrier C 122 and carrier D 124 , into a communication channel. This type of carrier aggregation is called intra-band carrier aggregation with non-continuous component carriers. Similarly, the aggregated carrier C 122 and carrier D 124 are called component carriers.

Please refer to FIG. 1D , which is a frequency schematic diagram of Type 3 and Type 4 of the carrier aggregation function. The type 3 carrier aggregation includes carrier A 112 and carrier B 114 located in the first band 110 , and carrier C 122 located in the second band 120 . The type 4 carrier aggregates carrier A 112 and carrier B 114 in the first band 110 , and carrier C 122 and carrier D 124 in the second band 120 . These two types of carrier aggregation are called inter-band carrier aggregation with non-continuous component carriers.

Among the above four types of carrier aggregation examples, except for the aggregation of continuous component carriers in the band of type 1, the other three types of carrier aggregation with discontinuous component carriers require multiple transceivers to cope. These transceivers are also referred to as radio frequency signal chains (RF chain), which generally refers to signal lines outside the baseband processor. Components such as antennas, mixers, oscillators, amplifiers, delay lines, etc., and combinations thereof may be included.

In the example of type 2 shown in FIG. 1C , since the carrier C 122 and the carrier D 124 are discontinuous, a non-carrier frequency is separated therebetween. If a single transceiver were used to cover this contiguous frequency, the transceiver would have to expend significant computational resources or time to remove signals at non-carrier frequencies. Generally, two transceivers are used to receive the signals of the carrier C 122 and the carrier D 124 respectively.

Similarly, in the examples of Type 3 and Type 4 shown in FIG. 1D , since the component carriers are located in different bands, that is, at least two component carriers are discontinuous, separated by non-carrier frequencies, So use multiple transceivers to deal with them separately. For example, in the form 3 example, one transceiver with a larger processing bandwidth can be used for carrier A 112 and carrier B 114 , and another transceiver can be used for carrier C 122 . In the example of form 4, in addition to the above two transceivers of form 3, a third transceiver is used to be responsible for the signal of the carrier D 124 .

In the case of type 1, a single transceiver with a larger processing bandwidth can be used to be responsible for the carrier A 112 and the carrier B 114, or two transceivers with a smaller processing bandwidth can be considered to be responsible for the carrier A 112 respectively. with carrier B114. Generally speaking, the signal quality received by a transceiver with a smaller processing bandwidth will be better. But its disadvantage is to take up excess volume, cost, and power consumption.

In summary, it can be known that in most of the carrier aggregation types, the wireless communication device must use more than two transceivers to support the carrier aggregation function. In fact, if the wireless communication device activates the carrier aggregation function, it usually means that the wireless communication device is performing high-speed transmission. If the base station and wireless carrier frequency resources are sufficient, the wireless communication device usually activates all transceivers to perform carrier aggregation communication. However, the wireless communication device is mobile, and the base station communicating with it may not always be able to maintain a good wireless channel environment. Once entering the range where another base station can provide better service, the wireless communication device must have the ability to know the information of another base station, so that the wireless communication network can handover the signal from the original base station to another base station, This enables wireless communication to maintain the original bandwidth level or even perform better.

However, since the wireless communication device has used all transceivers to support carrier aggregation communication, the wireless communication device cannot call one of the transceivers to receive information from another base station. Therefore, there is an urgent need for a wireless communication device and method for invoking one of the transceivers to receive information from another base station while satisfying the carrier aggregation function as much as possible. In addition, for a wireless communication device with multiple transceivers, even if it does not support the carrier aggregation function, it still needs to call one of the transceivers to receive information from another base station.

Detailed ways

The present invention will be described in detail in some embodiments as follows. However, the invention can be broadly implemented in other embodiments than the disclosed ones. The scope of the present invention is not limited by these examples, but rather by the appended claims. In order to provide a clearer description, even those of ordinary skill in the art can understand the content of the invention, the various parts in the illustrations are not drawn according to their relative sizes and proportions, and the proportions of certain dimensions and other relative dimensions will be different. It is highlighted and exaggerated, and irrelevant details are not fully drawn, in order to make the illustration simple and easy to understand.

Please refer to FIG. 2 , which is a schematic diagram of a connection between a wireless communication device and a wireless network according to an embodiment of the present invention. The wireless communication device 200 has multiple sets of transceivers and is wirelessly connected to the wireless network through at least one first base station 210 . The wireless communication device 200 and the first base station 210 may support the carrier aggregation function, and can perform wireless communication in the form of carrier aggregation through multiple carriers of types 1 to 4 mentioned in the prior art. In an embodiment of the present invention, the wireless communication device 200 may perform wireless communication through a plurality of first base stations 210 . However, among the plurality of first base stations 210, there will be at least one first base station 210 providing main services, especially providing control signals. In order to simplify the description, the present invention uses the first base station 210 to replace the above-mentioned plurality of first base stations 210 providing wireless services.

When the wireless communication device 200 moves, it may enter the radio coverage of other base stations. For example, the wireless communication device 200 may enter a building, and a second base station 220 may be installed inside the building. The second base station 220 may be a pico-cell or a femto-cell, which is specially used to provide wireless access capability inside the building. In another example, the wireless communication device 200 may move to a location closer to a third base station 230 . In these two examples, since the distance between the second base station 220 and the third base station 230 is shorter than that of the first base station 210 , the wireless communication device 200 may be able to provide better quality of service.

In an embodiment, the aforementioned wireless communication device 200 may be a wireless communication device 200 conforming to Long Term Evolution-Advanced (LTE-A, Long Term Evolution-Advanced) technology. The above-mentioned first base station 210 may also be a base station conforming to the technology of the long-term evolution advanced version, which is called an evolved node B (eNodeB, Evolved Node B). The above-mentioned second base station 220 may be a home base station conforming to the technology of the long-term evolution advanced version, which is called a home evolution node B (HomeeNodeB). The above-mentioned third base station 230 may be an evolved Node B, or a base station conforming to other wireless technology standards, such as CDMA2000, W-CDMA, and TD-S-CDMA standards of code division multiple access technology. Those of ordinary skill in the art can understand that the implementation examples provided by the present invention can be applied to the LTE-A technology, because the technology supports the carrier aggregation function. The present invention is not limited to the LTE advanced version technology, as long as it is any wireless access device with multiple sets of transceivers, the device and method provided by the present invention can be used.

The aforementioned wireless network may include multiple base stations to provide coverage for wireless access by the wireless communication device 200 . In an actual wireless deployment situation, the number of second base stations 220 covering only a small area or an indoor area may be much more than the number of first base stations 210 covering a larger area. In particular, the design feature of the second base station 220 is that end users can quickly deploy and configure themselves, and even the wireless network operator (operator) may not know the actual deployment location of the second base station 220, so the wireless network operator's wireless A large number of second base stations 220 that change daily may not be included in the network design blueprint. However, if the wireless communication device 200 wants to enjoy better services provided by the second base station 220 , the wireless communication device 200 must transmit the information of the second base station 220 to the network through the first base station 210 .

In addition, a wireless network operator may only operate a wireless network of a certain standard technology. For example, the wireless network of operator A connects the first base station 210 and the second base station 220 , while operator B uses another wireless network of standard technology to connect to the third base station 230 . For operator A, the third base station 230 is not included in the blueprint of its wireless network design. But for the wireless communication device 200, if it is set to allow roaming and intercommunication between operator A and operator B, then if the wireless communication device 200 wants to enjoy the better service provided by the third base station 230, the wireless communication device 200 It is necessary to transmit the information of the third base station 230 to the wireless network of the operator A and/or the operator B through the first base station 210 .

In one embodiment, after the wireless communication device 200 moves, it must first detect the surrounding base station information (such as the wireless identification information of the base station) or measure the surrounding base station signals. The radio detection and measurement of surrounding base stations can be divided into two forms. One is intra-frequency measurement, in which the base station to be measured (such as the second base station 220 or the third base station 230 ) operates on the same carrier frequency as the first base station 210 . The other is inter-frequency measurement, in which the base station under test and the first base station 210 operate on different carrier frequencies.

Generally speaking, when the wireless communication device 200 is performing wireless communication with the first base station 210, in order to complete inter-frequency measurement, the first base station 210 will indicate which idle time or measurement gap (measurement gap) there is during communication through a wireless control signal. ), the wireless communication device 200 can detect surrounding base station information (such as physical cell identification information) or measure surrounding base station signals during these idle times or gaps. In this embodiment, if the first base station 210 knows the transceiver configuration of the wireless communication device 200, it can use the device and method provided by the present invention to specify which transceivers the wireless communication device 200 uses for measurement. In addition, the first base station 210 may not specify an idle time or a measurement gap for the wireless communication device 200 to perform inter-frequency measurement. In this embodiment, the wireless communication device 200 can autonomously use the device and method provided by the present invention to determine which transceivers to use for measurement.

In another embodiment, when the signal measurement result shows that the signal quality of the second base station 220 or the third base station 230 around the wireless communication device 200 is very good, the first base station 210 may need to further know the surrounding second base station 220 or the third base station Other information of the base station 230 (such as cell-wide identification information) for base station handover (hand-over or hand-off). However, the first base station 210 may not provide idle time or specify a measurement interval for the wireless communication device 200 to detect system information of the second base station 220 or the third base station 230 . In this embodiment, if the wireless communication device 200 with multiple sets of transceivers wants to measure the surrounding base stations without the first base station 210 providing idle time or specifying a measurement gap, it must use the Devices and methods. In addition, since the system information of the second base station 220 or the third base station 230 will only appear at a fixed time point, even if the network has a specified measurement gap, the wireless communication device 200 may still be unable to detect the second base station 220 in the specified measurement gap Or system information of the third base station 230 . In this embodiment, when the first base station 210 provides idle time or specifies a measurement gap, the wireless communication device 200 can still use the device and method provided by the present invention.

Generally speaking, when the wireless communication device 200 measures the wireless signals of the surrounding base stations, the identification signals of the surrounding base stations (such as the second base station 220 or the third base station 230 ) can be obtained through information contained in the wireless signals. By transmitting the identification signals of surrounding base stations, the wireless network to which the wireless communication device 200 is connected can switch the communication line from the original first base station 210 to the second base station 220 or the third base station 230 . After the base station handover (hand-over or hand-off) procedure, the primary serving base station of the wireless communication device 200 is handed over from the original first base station 210 to the second base station 220 or the third base station 230 . In addition, the first base station 210 and the second base station 220 or the third base station 230 may use the same or different radio access technology (radio access technology, RAT). If the first base station 210 and the second base station 220 or the third base station 230 use the same radio access technology, the handover behavior at this time is called an intra-RAT handover (Intra-RAT handover). If the first base station 210 and the second base station 220 or the third base station 230 use different radio access technologies, the handover behavior at this time is called inter-RAT handover (Inter-RAT handover).

In an embodiment of the present invention, due to the large number of femtocells or Home eNodeBs, the wireless identification information used to identify the second base station 220 in the wireless signal may be repeated. Even if the wireless communication device 200 measures the wireless identification information of the second base station 220, the network does not know which second base station 220 to switch the communication line to. For example, in the LTE advanced version technology, the radio identification information of each base station is called Physical Cell Identity (PCI, Physical Cell Identity), and there are only 512 different types of Physical Cell Identity information in total. If the place where the first base station 210 is set up is in a high-density metropolitan area, there may be tens of thousands of households within a radio coverage radius of several kilometers, and there may be thousands of micro base stations or home eNodeBs. In other words, multiple base stations may use the same physical cell identification information, especially femtocells or H-NodeBs. In another embodiment of the present invention, the wireless identification message of the third base station 230 using another wireless technology may not be understood by the wireless network.

If the wireless network cannot identify the base stations around the wireless communication device 200 through the wireless identification information such as the physical cell identification information, the wireless network may require the wireless communication device 200 to report the global identification information of the surrounding base stations within a certain period of time. The global identification information referred to here is exclusively used to indicate the base station. For example, in the LTE advanced version technology, the first base station 210 may issue a report cell global identity message command (reportCGI) to the wireless communication device 200, so that the wireless communication device 200 reports the cell global identity message (CGI) of surrounding base stations within a period of time. , Cell Global Identity). Since the global identification information can be used exclusively to represent the base station, it is usually included in the system information (System Information) broadcast by the base station. Different from the aforementioned wireless identification information, the wireless communication device 200 needs to receive and decode for a long time before it can parse out the global identification information. The gap time for receiving and decoding is determined by the wireless communication device 200 itself, and the first base station 210 will not inform the wireless communication device 200 when to receive the global identification message. Therefore, this gap time is called an autonomous gap, and the wireless communication device 200 autonomously determines which period of time can be spared to receive and analyze the global identification information of nearby base stations, and reports to the network through the first base station 210 .

In summary, no matter it is a measurement gap or an autonomous gap, as long as the wireless communication device 200 with multiple sets of transceivers uses at least one internal transceiver to receive information from nearby base stations, including radio signal strength, wireless identification information and/or Or global identification information can use the device and method provided by the present invention.

Please refer to FIG. 3 , which is a schematic block diagram of a wireless communication device 200 according to an embodiment of the present invention. The wireless communication device 200 supporting the carrier aggregation function may include multiple transceivers 310 (eg, transceivers 310-1, 310-2...310-N). According to the present invention, the wireless communication device 200 can be used in more than two transceivers supporting the carrier aggregation function.

Each transceiver 310 has the property of applicable band and band bandwidth. For example, in the Long Term Evolution (LTE, Long Term Evolution) technology, the carrier bandwidth in the same band can be 1.4, 3, 5, 10, 15 or 20 MHz. Therefore, the transceiver 310 suitable for the LTE technology or the LTE advanced version technology may be a transceiver that can only handle a relatively small bandwidth, or a transceiver that can handle a relatively large bandwidth. The wireless communication device 200 supporting the carrier aggregation function may include a transceiver 310, wherein the processing bandwidth of the transceiver 310 is greater than or equal to 20 MHz. At this time, the type of carrier aggregation that the transceiver 310 can handle may be limited to type 1 intra-band carrier aggregation with continuous component carriers. However, if the wireless communication device 200 supporting the carrier aggregation function includes multiple transceivers 310, wherein the processing bandwidth of each transceiver 310-1, 310-2, 310-N is less than 20MHz, then the transceiver 310 can handle In addition to the aggregation of continuous component carriers in the band of State 1, it can also handle the aggregation of non-continuous component carriers in the band of Type 2 (intra-band carrier aggregation with non-continuous component carriers), and the aggregation of Type 3 and Type 4, band Inter-band carrier aggregation with non-continuous component carriers.

Those skilled in the art can understand that the multiple transceivers 310 in the wireless communication device 200 may be of the same type or of different types. They can each cover the same band or different bands. They can have the same processing bandwidth or different processing bandwidths. The quantity and properties of the transceivers 310 depend on various applications, and the present invention does not limit the quantity and properties of the multiple transceivers 310 in the wireless communication device 200 .

The wireless communication device 200 further includes a communication module 320 for connecting to the above-mentioned multiple transceivers 310 for performing communication after aggregating multiple component carriers corresponding to the multiple transceivers 310 . For example, it is stipulated in a certain version of the LTE advanced technology that when the wireless communication device 200 performs carrier aggregation, a maximum of five component carriers can be aggregated. In other words, the wireless communication device 200 conforming to the LTE-Advanced specification may simultaneously have five transceivers 310 corresponding to five component carriers.

The wireless communication device 200 also includes a processing module 330, configured to select a first transceiver 310-1 from the plurality of transceivers 310 when using the plurality of transceivers 310 for communication at the same time, so that the transceiver stops Connect to the first base station 210 and start receiving information from the second base station 220 and/or the third base station 230 . The information of the second base station 220 and/or the third base station 230 includes wireless identification information and/or global identification information. The following embodiments are used to illustrate how to select at least one first transceiver 310 - 1 from the plurality of transceivers 310 to receive messages from surrounding base stations. When the wireless communication device 200 needs to open multiple measurement gaps or autonomous gaps to measure the radio signal strength of surrounding base stations or detect wireless identification information and/or global identification information, the device and method provided by the present invention can also be used. In another embodiment, the wireless communication device 200 may only perform wireless communication with the first base station 210 through the first transceiver 310-1 of the multiple transceivers 310, while the second transceiver 310-2 communicates with the third transceiver The detector 310-3 is designated to measure the signal strength of the second base station 220 and the third base station 230 respectively. At this time, if the network side requires the wireless communication device to receive the cell-wide identification message of another base station (not shown), the method of this patent can also receive the information from the second transceiver 310-2 and the third transceiver 310-3. An optimal transceiver is selected to receive the CGI message of another base station.

In an embodiment of the present invention, the processing module 330 may perform a first selection step, the first selection step includes selecting a second transceiver 310-2 among the plurality of transceivers 310, and making the second The transceiver 310-2 is further connected to the first base station 210 through the component carrier corresponding to the first transceiver 310-1, wherein the component carrier corresponding to the second transceiver 310-2 is the same as the component carrier corresponding to the first transceiver 310A. The corresponding component carriers belong to consecutive carriers of the same band.

In an embodiment of the present invention, the communication module 320 and the processing module 330 can be implemented on the same chip, or implemented in a wireless communication device. The chip or wireless communication device is used to connect the above-mentioned multiple transceivers 310 . The present invention does not limit the implementation manner of the transceiver 310 , the communication module 320 and the processing module 330 , nor does it limit whether they are implemented in the same chip.

Please refer to FIG. 4A , which is a schematic diagram of the first selection step performed by the wireless communication device 200 according to an embodiment of the present invention. In FIG. 4A , there are discontinuous first wave bands 410 and second wave bands 420 . In the first band 410 , there are three consecutive component carriers, namely carrier A 412 , carrier B 414 and carrier C 416 . In the second band 420 there are also consecutive carriers D 422 and E 424 . Before executing the first selection step, that is, below the dotted line shown in FIG. 4A , the wireless communication device 200 uses the first transceiver 310-1 corresponding to the carrier A 412, and the second transceiver 310-2 corresponding to the carrier B 414 and the carrier C. 416, and the third transceiver 310-3 corresponds to carrier D 422 and carrier E 424.

Assume that the bandwidth that the second transceiver 310-2 can handle is 20 MHz, and the sum of the bandwidths of the three consecutive carriers in the first band 410 is less than or equal to the bandwidth that the second transceiver 310-2 can handle. Then the first selection step will make the second transceiver 310-2 handle the wireless communication of the carrier A 412, so the first transceiver 310-1 can stop the wireless communication of the carrier A 412, and then receive the information of the surrounding base stations. The result of performing the first selection step is shown above the dashed line shown in Figure 4A.

Please refer to FIG. 4B , which is a schematic diagram of the first selection step performed by the wireless communication device 200 according to another embodiment of the present invention. Similar to FIG. 4A , there are three consecutive component carriers in the first band 410 , which are carrier A 412 , carrier B 414 and carrier C 416 . Before the original wireless communication device 200 performs the first selection step, the first transceiver 310-1 corresponds to the carrier A 412, the second transceiver 310-2 corresponds to the carrier B 414, and the third transceiver 310-3 corresponds to the carrier C 416.

In this embodiment, both the first transceiver 310 - 1 and the second transceiver 310 - 2 belong to the transceiver 310 with a processing bandwidth of 40 MHz, and the bandwidth of the carrier A 412 and the carrier B 414 are both 20 MHz. Since the receiving performance of using two transceivers 310 with narrower processing bandwidth to deal with two carriers respectively is higher than the receiving performance of using one transceiver 310 with wider processing bandwidth to deal with two carriers. Therefore, before performing the first selection step, the wireless communication device 200 respectively uses the first transceiver 310-1 and the second transceiver 310-2 with a processing bandwidth of up to 40 MHz to deal with the carrier A 412 and carrier A 412 with a bandwidth of only 20 MHz. B 414. After the first selection step, the wireless communication device 200 uses a single second transceiver 310-2 to handle carrier A 412 and carrier B 414, leaving the first transceiver 310-1 free to receive messages from surrounding base stations . In this embodiment, although the receiving performance of switching to a single second transceiver 310-2 will decrease, the overall impact is not great.

The existing two embodiments about the first selection step are all examples of frequency division duplexing (Frequency DivisionDuplexing, FDD), and then use the example shown in FIG. 4B to describe time division duplexing (Time DivisionDuplexing, TDD) Happening. The so-called frequency division multiplexing means that the uplink and downlink of the wireless communication device 200 and the base station use different frequencies. Generally, there is a fixed shift value between the uplink and downlink frequencies. Therefore, uplink and downlink wireless communications can be performed simultaneously. On the other hand, the uplink and downlink of the TDM wireless communication system use the same frequency, and the uplink or downlink communication is carried out by utilizing the uplink and downlink allocation periods known to both parties.

If the system shown in FIG. 4B is a time-division multiplexing system, the premise that the second transceiver 310-2 can handle carrier A 412 and carrier B 414 at the same time is that the uplink and downlink allocation periods of carrier A 412 and carrier B 414 must be exactly the same. Generally speaking, the uplink and downlink allocation period of a certain carrier can be fixed or known to both parties, and the use mode code is used to represent various modes of the uplink and downlink allocation period. Assuming that the uplink and downlink allocation periods of carrier A 412 and carrier B 414 are different, a single transceiver 310 cannot be used to handle the two carriers. If the uplink and downlink allocation periods of carrier A 412 and carrier B 414 are the same, or the codes of the uplink and downlink allocation modes are the same, a single second transceiver 310-2 can be used to deal with carrier A 412 and carrier B 414, leaving The first transceiver 310-1 is used to receive messages from surrounding base stations.

The main spirit of the first selection step is to re-allocate the corresponding relationship between the transceiver 310 and the component carrier, so that the transceiver 310 with sufficient processing bandwidth can cope with multiple consecutive components in the same band at the same time after reallocating the component carrier. carrier. Therefore, the wireless communication device 200 can free up at least one transceiver 310 for receiving information of surrounding base stations. It should be noted that, in the three above-mentioned embodiments, the multiple component carriers located in the same frequency band are all consecutive. If multiple component carriers located in the same band are discontinuous, the present invention can also be applied to the same transceiver 310 to process these discontinuous component carriers, although this transceiver 310 should be able to carry out the intermediate frequencies that do not belong to the carrier Special treatment to avoid non-carrier noise affecting the carrier part.

Please refer to FIG. 5A , which is a schematic diagram of the second selection step performed by the wireless communication device 200 according to an embodiment of the present invention. In FIG. 5A , there are two bands 510 and 520 in total, which respectively include three component carriers (carrier A 512 , carrier B 514 and carrier C 516 ) and two component carriers (carrier D 522 and carrier E 524 ). The two transceivers 310 - 1 and 310 - 2 included in the wireless communication device 200 respectively correspond to multiple carriers in the two bands 510 and 520 . The main spirit of the second selection step is to select the transceiver 310 corresponding to the least number of component carriers among the plurality of transceivers 310 to reduce the impact on the overall communication.

In the embodiment shown in FIG. 5A , the number of component carriers corresponding to the first transceiver 310 - 1 is three, and the number of component carriers responsible for the second transceiver 310 - 2 is two. After the second selection step is performed, since the number of component carriers corresponding to the second transceiver 310-2 is the least, it is selected to let the second transceiver 310-2 stop wireless communication on the component carriers 522 and 524, and make the second transceiver 310-2 310-2 receives messages from surrounding base stations.

Please refer to FIG. 5B , which is a schematic diagram of the second selection step performed by the wireless communication device 200 according to another embodiment of the present invention. It can be seen that in FIG. 5B, the first transceiver 310-1 corresponds to only one component carrier, while the second transceiver 310-2 and the third transceiver 310-3 both correspond to two component carriers, so the second choice The step selects the first transceiver 310-1 to stop the wireless communication on the component carrier 512, and makes the first transceiver 310-1 receive the information of the surrounding base stations.

Please refer to FIG. 5C , which is a schematic diagram of the second selection step performed by the wireless communication device 200 according to another embodiment of the present invention. It can be seen that in FIG. 5C, the first transceiver 310-1 corresponds to only one component carrier, while the second transceiver 310-2 and the third transceiver 310-3 both correspond to two component carriers, so the second choice The step selects the first transceiver 310-1 to stop the wireless communication on the component carrier 512, and makes the first transceiver 310-1 receive the information of the surrounding base stations.

Please refer to FIG. 5D , which is a schematic diagram of the second selection step performed by the wireless communication device 200 according to another embodiment of the present invention. It can be seen that in FIG. 5D, the first transceiver 310-1, the second transceiver 310-2, and the third transceiver 310-3 are only corresponding to one component carrier, while the fourth transceiver 310-4 is corresponding to two component carriers. component carriers. Therefore, as shown in FIG. 5D, the second selection step can produce three kinds of results, respectively selecting the first transceiver 310-1, the second transceiver 310-2 or the third transceiver 310-3 to receive the signals of surrounding base stations. message.

Please refer to FIG. 6A , which is a schematic diagram of the third selection step performed by the wireless communication device 200 according to an embodiment of the present invention. In FIG. 6A , there are two bands 610 and 620 in total, which respectively include three component carriers (carrier A 612 , carrier B 614 and carrier C 616 ) and two component carriers (carrier D 622 and carrier E 624 ). The two transceivers 310 - 1 and 310 - 2 included in the wireless communication device 200 correspond to multiple carriers in the two bands 610 and 620 respectively. The main spirit of the third selection step is to select multiple transceivers 310 in turn. In the embodiment shown in FIG. 6A , the wireless communication device 200 includes two transceivers 310 - 1 and 310 - 2 , which are vacated in turn to receive messages from surrounding base stations.

Please refer to FIG. 6B , which is a schematic diagram of the third selection step performed by the wireless communication device 200 according to another embodiment of the present invention. In this embodiment, the third selection step may use a weighted round-robin approach. For example, the number of component carriers supported by each transceiver 310 is used as the weighting number. In FIG. 6B , the number of component carriers supported by the first transceiver 310 - 1 is three, and the number of component carriers supported by the second transceiver 310 - 2 is two. Therefore, the proportion of times that the first transceiver 310-1 is selected is two out of five, and the proportion of times that the second transceiver 310-2 is selected is three out of five. In FIG. 6B , it can be seen that the result of performing the third selection step five times, the first transceiver 310-1 is selected twice, and the second transceiver 310-2 is selected three times.

In addition to the number of component carriers shown in FIG. 6B as the calculation basis, the above weighting number may also use the sum of the bandwidths of the component carriers or the bandwidth processing capability of the transceiver 310 as the calculation basis. Those skilled in the art can understand that, in one embodiment, when the sum of the bandwidths of the component carriers that a certain transceiver 310 handles is wider, the proportion that is selected will be smaller. In another embodiment, when the sum of bandwidths that a certain transceiver 310 can handle is wider, the proportion that is selected will be smaller.

In the fourth selection step provided by the present invention, which transceiver 310 to select is mainly determined according to the state of the transceiver 310 and/or the component carrier. In one embodiment, it is assumed that the bandwidth processing capability of the first transceiver 310-1 is 60 MHz, and the bandwidth processing capability of the second transceiver 310-2 is 40 MHz. Then the fourth selection step will select the second transceiver 310-2 to receive the information of the surrounding base stations. In another embodiment, it is assumed that the total bandwidth of the component carriers supported by the first transceiver 310 - 1 is 60 MHz, and the total bandwidth of the component carriers supported by the second transceiver 310 - 2 is 40 MHz. Then the fourth selection step will select the second transceiver 310-2 to receive the information of the surrounding base stations. In yet another embodiment, the fourth selecting step is mainly to select the corresponding transceiver 310 according to the receiving and/or transmitting status of the component carrier. Assuming that the channel quality indicator (CQI, channel quality indicator) of a component carrier is the worst among all the component carriers, the fourth selection step is to select the transceiver 310 corresponding to the component carrier for receiving the information of surrounding base stations. In the above three embodiments, the fourth selection step is mainly to select the transceiver 310 that least affects the communication performance according to the state of the transceiver 310 and/or the component carrier.

In the fifth selection step provided by the present invention, it is mainly determined which transceiver 310 to select based on the content carried by the component carrier. In one embodiment, if a certain component carrier carries a control signal, such as a channel control signal or an upper layer signaling of a communication protocol stack, then the fifth selection step avoids selecting the transceiver 310 corresponding to the component carrier. In another embodiment, when a component carrier communicates with a serving primary base station (primary cell), and another component carrier communicates with a serving secondary base station (secondary cell), the fifth selecting step It will avoid selecting the transceiver 310 corresponding to the component carrier communicating with the primary base station. In yet another embodiment, when one component carrier carries real-time or real-time data and another component carrier carries non-real-time or non-real-time data, the fifth selection step will avoid selecting real-time data. The transceiver 310 corresponding to the component carrier of the data.

In other words, the fifth selection step selects a transceiver corresponding to a component carrier conforming to a communication content according to the content carried by the component carrier. In the above three embodiments, the above-mentioned communication content may include non-control signals, non-real-time or non-immediate information, or information for communicating with the secondary base station.

In the sixth selection step provided by the present invention, the main task is to select the transceiver that least affects the uplink communication. In the half-duplex or time-division multiplexing communication mode, uplink and downlink communication do not occur simultaneously. However, in a full-duplex or FDM communication mode, uplink and downlink communications may occur simultaneously. However, when a transceiver 310 is used to receive information from surrounding base stations, the transceiver 310 may not be able to send an uplink signal to the first base station 210 . Therefore, the sixth selection step is to use this feature to select the transceivers 310 corresponding to component carriers that only receive downlink signals but do not send out uplink signals. In this way, the communication of those component carriers that send uplink signals will not be affected.

Please refer to FIG. 7 , which is a schematic diagram of the sixth selection step performed by the wireless communication device 200 according to an embodiment of the present invention. Two transceivers 310 are shown in FIG. 7 . The first transceiver 310 - 1 corresponds to the three carriers 712 , 714 and 716 of the first band 710 . The second transceiver 310 - 2 corresponds to two carriers 722 and 724 of the second band 720 . In this embodiment, the three component carriers in the first band 710 do not require the first transceiver 310-1 to send uplink signals, while the two component carriers in the second band 720 require the second transceiver 310-2 to send out uplink signals. Signal. Therefore, in the sixth selection step, the transceiver 310 corresponding to the component carrier that does not need to transmit uplink signals is selected, that is, the first transceiver 310 - 1 shown in FIG. 7 , to receive information from surrounding base stations.

Please refer to FIG. 8 , which is a flowchart of a step of a wireless communication method according to an embodiment of the present invention. The wireless communication method is applicable to a wireless communication device with multiple transceivers, wherein each of the above-mentioned transceivers is used to connect to at least one first base station through at least one component carrier.

In step 810, communication is performed according to a plurality of component carriers corresponding to the plurality of transceivers. In another example, step 810 may be performing communication after aggregating multiple component carriers corresponding to the multiple transceivers. The present invention does not limit the devices and methods that must be applicable to support carrier aggregation.

Next, in step 820, when the multiple transceivers are used for communication simultaneously, a first transceiver is selected from the multiple transceivers.

Finally, in step 830, make the first transceiver stop connecting to the first base station and start receiving information from at least one second base station.

In step 820, selecting a first transceiver from among the plurality of transceivers may include one of multiple selection steps. Please refer to FIG. 9A , which is a detailed flowchart of an embodiment of step 820 in FIG. 8 .

From the above explanation, the first selection step can select a transceiver to replace the first transceiver, and use the first transceiver to receive the information of the surrounding base stations under the condition that the communication performance is minimally affected. Therefore, in the embodiment shown in FIG. 9A , the first selection step is preferentially performed, and only when the first transceiver cannot be selected by the first selection step, other selection steps are used. Therefore, at the beginning, the first selection step 910 is performed to select a second transceiver among the plurality of transceivers, and make the second transceiver connect to the first transceiver through the component carrier corresponding to the first transceiver. In the base station, the component carrier corresponding to the second transceiver and the component carrier corresponding to the first transceiver belong to continuous carriers of the same band.

Next, in step 912, it is determined whether the first transceiver is selected. If the first transceiver has been selected by the first selection step 910, the flow proceeds to step 830 shown in FIG. 8 . However, if the first selection step 910 cannot find a second transceiver to replace the first transceiver, step 914 is performed to perform one of the following multiple selection steps, and when the first transceiver cannot be selected, execute Any combination of the remaining selection steps until the first transceiver is selected. The multiple selection steps here include:

In the second selection step 920, select a transceiver with the least number of corresponding component carriers among the plurality of transceivers.

In the third selecting step 930, the transceivers among the plurality of transceivers are selected in turn. The rotation of the plurality of transceivers includes one of the following methods: fair rotation; and weighting according to a characteristic value of each transceiver, and then taking turns according to the weighted proportion, wherein the characteristic value includes at least one of the following Or any combination thereof: the bandwidth processing capability of each transceiver; and the number of component carriers corresponding to each transceiver.

The fourth selection step 940 is to select the transceiver with the least influence according to the states of the component carriers corresponding to the multiple transceivers. In one embodiment, the transceiver with the least impact corresponds to the component carrier with the worst channel quality among the plurality of component carriers. In another embodiment, the sum of bandwidths of component carriers corresponding to the transceiver with the least impact is smaller than the sum of bandwidths of component carriers corresponding to other transceivers.

In the fifth selection step 950, according to the communication content carried by the component carriers corresponding to the plurality of transceivers, select a transceiver corresponding to the component carrier that meets a communication content. In one embodiment, the communication content does not include any one of the following or any combination thereof: messages communicated with a primary cell; control messages; and real-time messages.

The sixth selecting step 960 is to select a transceiver corresponding to the component carrier that does not transmit signals according to whether the component carriers corresponding to the plurality of transceivers transmit signals or not. In one embodiment, at least one component carrier among the plurality of component carriers is not used to transmit signals, and the component carrier corresponding to the first transceiver selected in the sixth selection step includes the component carrier not used to transmit signals .

Please refer to FIG. 9B , which is a detailed flowchart of another embodiment of step 820 in FIG. 8 . Different from FIG. 9A, the first selection step 910 is not performed preferentially in the embodiment of FIG. 9B. Therefore, step 916 will execute one of the above multiple selection steps 910-960, and when the first transceiver cannot be selected or the selected transceiver cannot operate in the frequency band of the base station to be tested, any of the remaining selection steps will be executed. combination until the first transceiver is selected.

In summary, the wireless communication device and method provided by the present invention can call one of the transceivers to receive information from another base station while maintaining the communication performance as much as possible. For a wireless communication device with multiple transceivers, even if the carrier aggregation function is not supported, one of the transceivers can be called to receive information from another base station. Although in the process of invoking the transceiver, part of the communication content transmitted by part of the carrier may be sacrificed. However, in terms of the overall communication efficiency, if it is possible to switch to the base station providing better wireless services earlier, there is no need to sacrifice the wireless communication efficiency of each component carrier. From this point of view, the wireless communication device and method provided by the present invention can improve the efficiency of wireless spectrum usage, and further save time and energy for wireless signal processing.
