Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The first embodiment is as follows:
referring to fig. 1, the present embodiment provides a radio frequency transceiver circuit, which includes a main transmitting circuit 10, a receiving circuit, and at least two antennas; the at least two antennas comprise a first antenna 31 and a second antenna 32, the main transmitting circuit 10 is connected with the first antenna 31 in a working state, and is fixed to transmit signals through the first antenna 31; the receiving circuit includes a main set receiving circuit 21 and a diversity receiving circuit 22, the main set receiving circuit 21 is connected to the first antenna 31 or the second antenna 32 through the switching circuit 40 to receive signals, and the diversity receiving circuit 22 is connected to an antenna which is not connected to the main set receiving circuit 21 through the switching circuit 40 to receive signals; the switching circuit 40 is configured to switch the connection relationship between the main receiver 21, the diversity receiver 22, and each antenna when the antenna switching condition is satisfied.
The radio frequency transceiver circuit is a circuit which is arranged on the terminal equipment and is used for transmitting and receiving radio frequency signals, wherein most of the radio frequency signals are communicated with the base station, and of course, the radio frequency transceiver circuit can also be used for realizing radio frequency communication with other equipment. The radio frequency transceiver circuit disposed on the terminal device generally includes at least two antennas, and each antenna may have both a radio frequency transmitting function and a radio frequency receiving function, or may have only a radio frequency transmitting function and only a radio frequency receiving function. For convenience of description, the antennas in the embodiment of the present invention at least include a first antenna 31 and a second antenna 32, where the difference numbers of the first antenna 31 and the second antenna 32 only indicate that the two antennas have a difference in position, and indicate that the terminal is provided with at least two antennas, and the specific form of the antennas is not limited to how different the antennas are. In a specific usage environment, the first antenna 31 and the second antenna 32 may be applied as a transmitting antenna, a receiving antenna, or a transceiving antenna.
The radio Frequency transceiver circuit in the embodiment of the present invention may be applied to an FDD (Frequency Division duplex) radio Frequency circuit or a TDD (Time Division duplex) radio Frequency circuit; therein, FDD, i.e. frequency division duplex, refers to the operation of the uplink (terminal equipment to base station) and downlink (base station to terminal equipment) using two separate frequencies (with a certain frequency separation requirement), which operate on symmetrical frequency bands. FDD is suitable for wireless communication systems that provide a single radio frequency channel for each user. FDD technology provides two distinct frequency bands for each user: a forward frequency band (also referred to as a forward channel) providing a signal transmission channel (downlink channel) from a base station to a mobile user, and a reverse frequency band (also referred to as a reverse channel) providing a signal transmission channel (uplink channel) from a mobile user to a base station. In FDD, any duplex channel is actually composed of two simplex channels, with a device called a duplexer in the user and base stations that allows simultaneous wireless transmission and reception on the duplex channel. The frequency separation of the forward and reverse channels is fixed throughout the system and should be as large as possible across the spectrum of the communication system in order to minimize interference between the forward and reverse bands on each user channel. The transmitting circuit corresponds to an uplink channel and the receiving circuit is applied to a downlink channel.
TDD, time division duplex, is a duplex mode of a communication system, used for separating reception and transmission channels in a mobile communication system. In the TDD mode mobile communication system, the receiving and transmitting are in different time slots of the same frequency channel, namely carrier, and the receiving and transmitting channels are separated by using the guaranteed time; in the FDD mode, the receiving and transmitting are performed on two separate symmetric frequency channels, and the receiving and transmitting channels are separated by a guaranteed frequency band.
The characteristics and communication benefits of mobile communication systems employing different duplex modes are different. The uplink and downlink channels in the TDD mode mobile communication system use the same frequency, and thus have reciprocity of the uplink and downlink channels, which brings many advantages to the TDD mode mobile communication system.
In TDD mode, the transmission of information in uplink and downlink can be performed on the same carrier frequency, i.e. the transmission of information in uplink and the transmission of information in downlink are realized by time division on the same carrier.
The rf transceiver circuit in this embodiment includes a main transmitter circuit 10 and a receiver circuit. The main transmitting circuit 10 is connected to the first antenna 31, and transmits signals through the first antenna 31. It is shown here that the main transmitting circuit 10 is not switched in the embodiment of the present invention, and there is a fixed connection relationship between the antennas, and the transmitting antenna is not switched. The main transmitting circuit 10 is connected to the first antenna 31, which is only to indicate the fixing property of the antenna connected to the main transmitting circuit 10, and does not limit which antenna is specific, and those skilled in the art know that the main transmitting circuit 10 may also be connected to the second antenna 32, or other antennas, as long as the rf transmitting chain is fixed. In this embodiment, the main transmitting link includes the above-mentioned main transmitting circuit 10 and an accessed antenna.
The receiving circuit includes a main set receiving circuit 21 and a diversity receiving circuit 22. Diversity reception is a major anti-fading technique, which can greatly improve the reliability of multipath fading channel transmission, and in practical mobile communication systems, mobile stations often work in urban building groups or other complex geographical environments, and the speed and direction of movement are arbitrary. Diversity reception techniques are considered to be significantly effective and cost effective anti-fading techniques. The basic idea of diversity is to separate the received multipath signals into uncorrelated (independent) multipath signals and then combine the energy of the separated multipath signals according to a certain rule to maximize the energy of the received useful signal, thereby improving the signal-to-noise ratio of the received signal. Thus, diversity reception includes two aspects: firstly, how to separate the received multipath signals to make them mutually uncorrelated, and secondly, properly combining the separated multipath signals to obtain the maximum signal-to-noise ratio.
Diversity is classified into macro diversity and micro diversity. Macro diversity, also known as multi-base station diversity, has the primary effect of being resistant to slow fading. For example, in a mobile communication system, a plurality of base stations are located at different physical locations (e.g., diagonals of a cell) and simultaneously transmit the same signal, and mobile stations in the cell select the best base station to communicate with to reduce slow fading caused by terrain, and the atmosphere.
The diversity receiving link, receiving only and not transmitting, the terminal device will combine the signals received from the main set receiving link and the diversity receiving link, so as to obtain the diversity gain, therefore the diversity gain here is the receiving gain.
Diversity reception is mainly to counteract the effect of fast fading on the received signal, because the signal generates multipath component signals due to interference such as reflection and the like in the transmission process, the receiving end simultaneously receives signals of different paths by using multiple antennas, and then selects and combines the signals into an overall signal to reduce the effect of signal fading, which is called diversity reception. Diversity is to combine the signals obtained by dispersion in a centralized manner, and if several signals are independent of each other, the maximum signal gain can be obtained after proper combination.
In the present embodiment, the primary set receiving chain includes the primary set receiving circuit 21 and the connected antennas described above; the diversity receive chain is similar and includes diversity receive circuitry 22 and connected antennas.
The main set receiving circuit 21 and the diversity receiving circuit 22 are both for reception of radio frequency signals; both receive signals via different antennas, and if the main set receiving circuit 21 connects the first antenna 31 to receive signals, the diversity receiving circuit 22 connects the second antenna 32 to receive signals. Of course, if there are more antennas, the main receiver circuit 21 or the diversity receiver circuit 22 may be connected to other antennas as long as they have different antennas.
The switching circuit 40 is connected to both the main receiver circuit 21 and the diversity receiver circuit 22, and functions to switch the connection relationship between the main receiver circuit 21, the diversity receiver circuit 22, and the antenna. The switching may include at least swapping the antennas to which the main set reception circuit 21 and the diversity reception circuit 22 are connected. That is, if the first antenna 31 to which the main set receiving circuit 21 is connected and the second antenna 32 to which the diversity receiving circuit 22 is connected, the main set receiving circuit 21 may be connected to the second antenna 32 and the diversity receiving circuit 22 may be connected to the first antenna 31 by the switching circuit 40.
In some embodiments, the switching circuit 40 may specifically include a double pole double throw switch circuit, i.e., a DPDT.
In some embodiments, a switch circuit 50 may be further provided on a line where the main transmission circuit 10 and the reception circuit are connected to the first antenna 31. The switching circuit 50 functions as a signal transfer device when the transmitting circuit and the receiving circuit share one antenna, i.e., the first antenna 31, so that the isolation between the transmitting signal and the receiving signal can be realized, and the transmitting signal is ensured to be transmitted only to the antenna, and the receiving signal is only transmitted to the receiver in the terminal equipment. When applied to an FDD rf circuit, the specific component of the switching circuit 50 may be a duplexer Diplexer 51. The duplexer 51 has one end connected to the main transmitting circuit 10 and the receiving circuit, and the other end connected to the first antenna 31. The main receiver circuit 21 and the diversity receiver circuit 22 in the receiver circuit can be connected to the first antenna 31 through the duplexer 51, please refer to fig. 2.
In some embodiments, a filter 60 may also be included, the filter 60 being generally provided only on the receiving circuit where the duplexer is not provided, and the filter 60 being provided on the line where the receiving circuit is connected to the antenna. Depending on the transceiving function of the antennas, the filter 6060 may be provided only on some of the antennas, or all of the antennas may be provided. If a duplexer is connected to the receiving circuit, the filter 60 is not required to be provided, and therefore the filter 60 is generally provided only between the receiving circuit to which the duplexer is not connected and the antenna. In the case of FDD rf circuits, a filter 60 is provided at least on the second antenna 32, see fig. 3.
In some embodiments, the first antenna 31 is disposed below the terminal device, and the second antenna 32 is disposed above the terminal device; in the initial state, the main transmission circuit 10 and the diversity reception circuit 22 are both connected to the first antenna 31. For a terminal device, the antenna is usually disposed on the housing of the terminal, and at least two antennas are disposed on the top and bottom of the terminal device respectively; the antenna at the bottom is usually held by a user, and if the antenna is held by the user, the related art may not receive the radio frequency signal; at this time, the connection relationship between the main set receiving circuit 21 and the diversity receiving circuit 22 and the antenna can be switched by the switching circuit 40 to solve this problem.
In some embodiments, the diversity receive circuit 22 may include at least one; when the diversity receiving circuit 22 includes at least two, in an operating state, each diversity receiving circuit 22 accesses a different antenna. The terminal equipment can be provided with a plurality of diversity receiving links to improve the strength and stability of receiving the radio frequency signals; if a plurality of diversity receiving chains are provided, the antennas connected to the respective diversity receiving circuits 22 are different, and therefore the number of antennas can be increased accordingly.
The embodiment provides a radio frequency transceiver circuit, which comprises a main transmitting circuit 10, a receiving circuit and at least two antennas; the at least two antennas comprise a first antenna 31 and a second antenna 32, the main transmitting circuit 10 is connected with the first antenna 31 in a working state, and is fixed to transmit signals through the first antenna 31; the receiving circuit includes a main set receiving circuit 21 and a diversity receiving circuit 22, the main set receiving circuit 21 is connected to the first antenna 31 or the second antenna 32 through the switching circuit 40 to receive signals, and the diversity receiving circuit 22 is connected to an antenna which is not connected to the main set receiving circuit 21 through the switching circuit 40 to receive signals; the switching circuit 40 is configured to switch the connection relationship between the main receiver 21, the diversity receiver 22, and each antenna when the antenna switching condition is satisfied. Therefore, the embodiment of the invention separates the main transmitting circuit 10 and the main receiving circuit 21, only switches the receiving circuit during switching, avoids SAR standard exceeding caused by main transmitting antenna switching, can effectively improve the quality of received signals of a radio frequency receiving link, and improves the performance of radio frequency transceiving
Example two:
the present embodiment provides a radio frequency switching method, please refer to fig. 4, the radio frequency switching method includes:
s401, detecting the current signal receiving quality of the terminal equipment; the terminal equipment comprises a radio frequency transceiving circuit in the embodiment of the invention;
s402, when the current signal receiving quality of the terminal equipment is detected to be less than or equal to a preset threshold value, controlling a switching circuit, and switching the connection relation among the main set receiving circuit, the diversity receiving circuit and each antenna.
The radio frequency switching method in the embodiment comprises the radio frequency transceiver circuit in the embodiment; when the switching condition is satisfied, the connection relationship between the main set receiving circuit, the diversity receiving circuit and each antenna can be switched by the switching circuit.
The radio frequency switching method in this embodiment switches the connection relationship between the receiving circuit and the antenna only in the radio frequency receiving direction, and does not involve switching of the main transmitting circuit, thereby avoiding the problem that the SAR exceeds the standard due to switching of the main transmitting circuit, and effectively utilizing the radio frequency performance of the radio frequency transmitting circuit.
When detecting the current signal reception quality of the terminal device, only the quality of the radio frequency signal received by the master set receiving circuit may be detected, that is, the quality of the radio frequency reception signal takes the quality of the radio frequency signal received by the master set receiving circuit as priority.
In some embodiments, after switching the connection relationship between the main set receiving circuit, the diversity receiving circuit and each antenna, the method further includes:
comparing the signal receiving quality of the terminal equipment before and after switching;
when the signal receiving quality is higher after the switching, the switching is finished; when the signal reception quality is lower after the handover, the connection relationship before the handover is switched back. If the radio frequency transceiver circuit receives a stronger radio frequency signal after the connection relationship among the main diversity receiving circuit, the diversity receiving circuit and each antenna is switched by the switching circuit, the switching is normal, probably because the signal strength is influenced by the gesture of holding the terminal equipment by a user, and better quality of the received radio frequency signal can be obtained by switching; if the receiving quality of the radio frequency signal is worse after the switching of the switching circuit, which indicates that the signal intensity of the environment is poor with high probability, the connection relationship among the main set receiving circuit, the diversity receiving circuit and the antenna is switched at the moment, which can not improve the receiving of the radio frequency signal, so that the connection mode with the best signal receiving intensity can be adopted; if the terminal is a double-antenna terminal, the terminal can be directly switched back through the switching circuit; if there are multiple antennas, then an attempt can be made to switch between the multiple antennas to find the best signal reception quality.
