Detailed Description
To make the objects, embodiments and advantages of the present application clearer, the following description of exemplary embodiments of the present application will clearly and completely describe the exemplary embodiments of the present application with reference to the accompanying drawings in the exemplary embodiments of the present application, and it is to be understood that the described exemplary embodiments are only a part of the embodiments of the present application, and not all of the embodiments.
All other embodiments, which can be derived by a person skilled in the art from the exemplary embodiments described herein without inventive step, are intended to be within the scope of the claims appended hereto. In addition, while the disclosure herein has been presented in terms of one or more exemplary examples, it should be appreciated that aspects of the disclosure may be implemented solely as a complete embodiment.
It should be noted that the brief descriptions of the terms in the present application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of the present application. These terms should be understood in their ordinary and customary meaning unless otherwise indicated.
The terms "first," "second," "third," and the like in the description and claims of this application and in the above-described drawings are used for distinguishing between similar or analogous objects or entities and are not necessarily intended to limit the order or sequence of any particular one, Unless otherwise indicated. It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein.
Furthermore, the terms "comprises" and "comprising," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a product or device that comprises a list of elements is not necessarily limited to those elements explicitly listed, but may include other elements not expressly listed or inherent to such product or device.
The radio frequency transceiver is installed in a communication device for receiving and transmitting signals of a set frequency band. The communication device may be a mobile phone, a computer, an ipad, and the like, which is not limited in this embodiment of the present invention. A radio frequency transceiver generally has a plurality of ports, each of which can be configured to receive signals in several frequency bands, but each of the ports can only receive signals in one of the frequency bands at the same time, that is, several frequency bands set in the same port cannot work simultaneously.
With the rapid development of communication technology, communication devices generally have multiple communication specifications, each of which includes not only one communication band but also possibly multiple communication bands, and under such communication specifications, the multiple communication bands need to operate simultaneously. For example, MIMO (multiple Input multiple Output), multiple CA (Carrier Aggregation) combination, endec (Eutra-NR Dual Connectivity, 4G and 5G Dual Connectivity), and the like are to be implemented in the 5G overseas scheme.
For example, the communication specification is CA _2A-3A, under this communication specification, the communication bands of Band2 and Band3 should operate simultaneously at the main set antenna and at the diversity antenna. The two communication bands cannot necessarily communicate through the same port. For convenience of description, Band2 is abbreviated herein as B2.
For example, the communication specification is B3 MIMO, under this communication specification, the communication bands of B3_ P and B3_ PM operate simultaneously at the main set antenna, and the communication bands of B3_ D and B3_ DM operate simultaneously at the diversity antenna, then for main set reception, the communication bands of B3_ P and B3_ PM cannot necessarily communicate through the same port, and the communication bands of B3_ D and B3_ DM cannot necessarily communicate through the same port.
For example, the communication specification is DC _2A _3A, under this communication specification, the communication bands of B2 and n3 should operate simultaneously at the main set antenna and simultaneously at the diversity antenna. The two communication bands cannot necessarily communicate through the same port.
The embodiment of the invention provides a radio frequency receiving method, which includes firstly determining which communication frequency bands are supported by each port of a radio frequency transceiver chip, and which frequency bands are supported by each port of the chip and are set by a research and development manufacturer of the chip. And setting the corresponding relation between the ports and the frequency bands according to the frequency bands supported by the ports of the chip. Table 1 shows a possible setting of the correspondence between each port of the chip and the frequency band.
TABLE 1
As shown in table 1, the rf transceiver is divided into a main path receiving port and a sub path receiving port, and a signal in any frequency band needs to be received by one port in the main path receiving port and one port in the sub path receiving port at the same time. For example, the port 8 supports bands Bx, Bb, and nx (x and B are arbitrary numbers, B represents a 4G signal, and n represents a 5G signal), and the port 7 supports bands Bx, Bc, By, and nx … …, so that designers can set a received band for each port according to the bands supported By each port and various specifications of the communication device. For example, for the communication specification DC _ cA _ nxA, it is necessary to operate the frequency bands Bc and nx simultaneously, and in the sub-channel reception, the port 8 is provided to receive nx _ D (D represents sub-channel reception), the port 7 is provided to receive Bc _ D, and in the main-channel reception, the port 1 is provided to receive nx _ P (P represents main-channel reception), and the port 2 is provided to receive Bc _ P. Then, since nx _ D and Bc _ D are set at different ports and nx _ P and Bc _ P are set at different ports, the two bands Bc and nx can operate simultaneously. After the frequency band is fixed at the corresponding port, the frequency band cannot be changed, when the specifications are more and more, conflicts can be generated between the frequency band and the frequency band, and then certain communication specifications cannot be realized.
For example, for the communication specification DC _ bA _ nxA, the frequency bands Bb and nx need to operate simultaneously, in the secondary reception, nx _ D is already fixedly set at the port 8, and the port supporting the frequency band Bb is only the port 8, so that the two frequency bands collide at the port 8 of the secondary reception and cannot operate simultaneously, and the communication specification DC _ bA _ nxA cannot be realized. Accordingly, the function of the communication specification cannot be realized, and the product competitiveness of the communication equipment is greatly limited.
The embodiment of the invention also provides a radio frequency receiving method, which only needs to increase flexible configuration of specifications in the radio frequency drive without changing or increasing peripheral circuits, and can flexibly adjust the receiving port corresponding to the communication frequency band according to different specifications.
Fig. 1 shows a possible radio frequency receiving method, which is suitable for communication devices with a plurality of communication specifications; a radio frequency transceiver having a plurality of ports disposed in the communication device, the method comprising:
In step 101, it is first determined that the communication specification of the communication device is switched from the first specification to the second specification.
When the frequency point signal transmitted by the base station near the communication equipment changes, the communication equipment can be switched to the second specification to search the signal of the communication frequency band in the second specification if the communication equipment can not search the signal of the communication frequency band included in the first specification.
Specifically, the embodiments of the present invention provide the following two ways to switch the specification.
In a first mode
And determining to switch the communication specification from the first specification to the second specification according to the pilot signals of the base stations searched by the communication equipment.
The base station can transmit pilot signals which are the same as the frequency points of the communication frequency bands, when the communication equipment determines that the signals cannot be searched according to the current communication specification such as a first specification, the pilot signals are searched, and when the searched pilot signals have the base station pilot signals which are the same as the frequency points of the frequency bands in a second specification, the communication specification is switched from the first specification to the second specification.
For example, the current first specification of the communication device is CA _2A-3A, and the frequency bands B2 and B3 operate simultaneously, and the current communication specification cannot be used when the communication device cannot search for any one or more of the frequency band signals B2 and B3. The communication device searches for the base station pilot signals, for example, three base station pilot signals B2, B4 and B5 are searched, the second specification CA _2A-4A is stored in the communication device, and the communication specification can be switched from the first specification to the second specification because the three searched base station pilot signals include two communication specifications of the second specification. The communication equipment uses the second specification, can receive the signal of each communication frequency band in the second specification, and the communication equipment can establish contact with the outside world.
The foregoing is by way of example only and is not intended as a limitation upon the embodiments of the present invention.
Mode two
And after searching that the signals of each frequency band included in the first specification exceed a preset time, switching the communication specification from the first specification to the second specification.
Whether to switch the communication specification is determined by the time length, for example, the first specification is CA _2A-3A, the frequency bands B2 and B3 operate simultaneously, when the communication device does not search for any one or more of the frequency band signals B2 and B3 to reach the preset time length, for example, 5s, which indicates that the current first specification cannot be used, the communication specification can be switched to the next communication specification of the first specification, that is, the second specification, in the preset order.
The foregoing is by way of example only and is not intended as a limitation upon the embodiments of the present invention.
In step 101, a first specification includes a plurality of frequency bands, each frequency band is provided with a different receiving port, and a first port of a radio frequency transceiver is configured to receive a signal of a first frequency band in the first specification for any two different frequency bands in the first specification, namely a first frequency band and a second frequency band; and setting a second port of the radio frequency transceiver to receive signals of a second frequency band in the first specification.
For example, the first specification is DC _ cA _ nxA, the first specification includes two frequency bands, Bc and nx, and the port 8 of the rf transceiver is configured to receive a signal in the nx frequency band; the port 7 is used for receiving signals in the Bc band.
In step 102, according to a set rule, a third port is configured to receive a signal in a first frequency band in the second specification, and the first port is configured to receive a signal in a third frequency band in the second specification; the first frequency band and the third frequency band are any two different frequency bands in the second specification; the third port supports receiving signals of the first frequency band and is not occupied by other frequency bands.
And when the communication specification is determined to be switched to the second specification, switching the ports according to the communication frequency band contained in the second specification. The second specification comprises a plurality of frequency bands, and the first frequency band and the third frequency band are any two different frequency bands in the second specification. Then, the receiving port of the first frequency band is switched from the original first port to the third port, and the first port is used for receiving the third frequency band.
It can be found that in the above-mentioned scheme provided in the embodiment of the present invention, the same frequency band can flexibly and dynamically replace the receiving port in different specifications, so that the communication device can use more communication specifications, realize more functions, and save cost without changing the hardware structure.
Table 2 shows another possible setting of the correspondence between each port of the chip and the frequency band.
TABLE 2
For example, the first specification is DC _ cA _ nxA, the first specification includes two frequency bands, Bc and nx, and the port 8 of the rf transceiver is configured to receive the signal of the nx frequency band; the port 7 is used for receiving signals in the Bc band. When it is determined that the communication specification is switched from the first specification to the second specification DC _ bA _ nxA, the second specification requires the frequency bands Bb and nx to operate simultaneously, and it can be found from table 2 that only the port 8 supports the frequency band of Bb, and therefore, in order to enable the second specification to be used in the communication device, the port 8 needs to be set to receive the signal of the frequency band of Bb, but nx is also set as the port 8 as a receiving port, which is obviously not proper, and since the port 7 also supports the frequency band of nx and the port 7 is not occupied by other frequency bands of the second specification, the port 7 is set as a receiving port of nx.
It can be seen that, in the above example, the frequency band nx is not fixed on a certain port, but can be adjusted in real time according to different specifications, when the communication specification is the first specification, the receiving port of the first frequency band nx is set as the port 8, and when the communication specification is the second specification, the receiving port of the first frequency band nx is set as the port 7. Because the ports are flexibly adjustable, both the first specification and the second specification can be used in the communication device without discarding either communication specification. This undoubtedly increases the communication specification of the communication apparatus, increasing the functions of the communication apparatus.
Specifically, the embodiment of the present invention provides two possible ways according to what specific rule the port is adjusted.
In a first mode
And after the communication frequency band is switched to the second specification, the receiving port of the communication frequency band in the second specification is judged in real time and adjusted in combination with the frequency band which can be supported by each port of the chip.
Specifically, it is determined that the second specification at least includes the first frequency band and the third frequency band, and the receiving port of the third frequency band can only be set as the first port, and the receiving port of the first frequency band is switched from the first port to a third port that supports receiving of the signal of the first frequency band and is not occupied by other frequency bands.
If the port corresponding to each frequency band of each specification is not set in advance, real-time judgment needs to be performed according to the current second specification. For example, the first specification is DC _ cA _ nxA, the first specification includes two frequency bands, Bc and nx, and the port 8 of the rf transceiver is configured to receive the signal of the nx frequency band; the port 7 is used for receiving signals in the Bc band. When it is determined that the communication specification is switched from the first specification to the second specification DC _ bA _ nxA, the two frequency bands Bb and nx in the second specification are determined in real time, it is determined that the receiving port of the third frequency band Bb can only be set as the first port, i.e., the port 8, each port supporting the first frequency band nx has the port 7 and the port 6 (taking the secondary receiving as an example, so that each port of the primary receiving is not involved, the adjustment of each port of the primary receiving is the same as the adjustment of each port of the secondary receiving), and neither the port 7 nor the port 6 is occupied by other frequency bands, then one port can be randomly selected for receiving the first frequency band nx, for example, the port 6 is selected for receiving the first frequency band nx.
Because the real-time judgment is carried out, after the communication specification is switched, the judgment process takes a certain time, so that the time consumption is long, but the port adjustment is more flexible.
Mode two
The designer designs the receiving ports corresponding to the frequency bands in the specifications in advance, and the designer considers the port conflict among the communication specifications when designing the port adjustment so as to design, so that the switching of the ports is directly carried out according to the previous design when the receiving ports are actually used, and the time is saved.
Specifically, according to receiving ports corresponding to frequency bands in preset specifications, determining that a receiving port corresponding to a first frequency band in the second specification is a third port, and determining that a receiving port corresponding to a third frequency band in the second specification is a first port;
switching the receiving port of the first frequency band to the third port, and switching the receiving port of the third frequency band to the first port; and each receiving port corresponding to each frequency band included in each preset specification is obtained by designing in advance according to the frequency band supported by each port of the radio frequency transceiver.
For example, in combination with table 2, a designer designs in advance a plurality of communication specifications supported by the communication device, and considers conflicts between ports during design, so as to obtain a receiving port mapping table corresponding to each frequency band of each communication specification as shown in table 3.
For example, when the communication device determines that the communication specification is switched from the first specification DC _ cA _ nxA to the second specification DC _ bA _ nxA, it determines the port 8 corresponding to the Bb frequency band and the port 6 corresponding to the nx frequency band in the second specification according to the preset table 2, and directly switches the receiving port of the Bb frequency band to the port 8 and switches the receiving port of the nx from the port 8 in the first specification to the port 6 without any judgment.
The above are merely examples, and embodiments of the present invention are not limited thereto.
Because real-time judgment is not needed, switching is directly carried out according to the receiving ports corresponding to the frequency bands in the preset specifications, the real-time judgment time is saved, and the accuracy is improved.
The radio frequency receiving method provided by the embodiment of the present invention is described again below by using a specific embodiment to facilitate understanding of the reader.
The first specification is By MIMO, which requires that, in secondary reception, By _ D and By _ DM operate simultaneously through different ports, and in primary reception, By _ P and By _ PM operate simultaneously through different ports, so that settings can be made according to the supported frequency bands of the ports of the rf transceiver.
Table 3 shows a possible frequency band setting of each port of the rf transceiver. Among the ports for the secondary reception, only the port 7 and the port 5 support the By band, and thus the By _ D and the By _ DM are respectively provided at the port 7 and the port 5. In each port of the main path reception, only port 3 and port 2 support the By band, and therefore, By _ P and By _ PM are respectively provided at port 2 and port 3. Then with such an arrangement, the first specification By MIMO can be used in the communication apparatus.
The second specification is CA _ bA-yA, and requires that the Bb band and the By band operate simultaneously on different ports received on the main path, and simultaneously operate on different ports received on the auxiliary path. In the secondary reception, the port 8 is set to receive signals of the band Bb _ D, and the port 5 is set to receive signals of the band By _ D, without port collision. However, in the primary reception, only port 2 supports the band Bb, so to make the second specification available, the receiving port of Bb _ P needs to be set as port 2, and the receiving port of By _ P needs to be switched to port 3 which supports the band By and is not occupied By other bands.
TABLE 3
Therefore, different receiving ports are switched in different communication specifications instead of fixing the receiving ports for each frequency band, the first specification and the second specification can be used in the communication equipment, the communication equipment can have more functions, and the practicability of the communication equipment is improved.
An embodiment of the present invention further provides a schematic structural diagram of a possible radio frequency transceiver, as shown in fig. 2, the radio frequency transceiver includes a plurality of ports in a primary reception PRX and a plurality of ports in a secondary reception DRX, and each port is configured to receive a signal in each communication frequency band.
