Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 2, a flowchart of a signal transmission control method according to an embodiment of the present invention is shown, for flexibly selecting a transmitting antenna, where the method includes the following steps:
201: and determining the receiving performance of each antenna in at least two antennas corresponding to the terminal, wherein each antenna respectively receives wireless signals and transmits wireless signals by adopting the same frequency band.
That is to say, for any one of the at least two antennas corresponding to the terminal: the antenna uses the same frequency band to receive wireless signals and transmit wireless signals, and the frequency band used by the antenna may be different from the frequency bands used by other antennas. If the terminal is in a TDD (Time Division duplex) mode, in the TDD mode, any one antenna corresponding to the terminal may receive and transmit a wireless signal using the same frequency band, so that the receiving performance and the transmitting performance of the antenna are the same, and thus, a transmitting antenna may be determined from at least two antennas according to the receiving performance of each antenna.
In this embodiment, one way to determine the reception performance of each antenna is: the signal strength of each antenna is determined, and the reception performance of each antenna is determined according to the signal strength of each antenna. If the signal strength is stronger, the receiving performance is better, so that the signal strength of each antenna can be sorted, and if the signal strength is sorted from high to low, the obtained sorting result can indicate the receiving performance of all antennas corresponding to the terminal, or a corresponding relation between the signal strength and the receiving performance is preset, and under the condition that the signal strength of each antenna is determined, the receiving performance of each antenna can be obtained according to the corresponding relation.
The signal strength of each antenna may be determined during a receiving time slot (i.e., when receiving a wireless signal), for example, as to the manner of determining the signal strength of each antenna and other manners of determining the receiving performance of each antenna, which is not described in detail in this embodiment.
202: and determining a transmitting antenna from the at least two antennas according to the receiving performance of each antenna of the at least two antennas. Any antenna corresponding to the terminal can receive wireless signals and transmit wireless signals by adopting the same frequency band, so that the receiving performance and the transmitting performance of the antenna are the same, and the transmitting antenna can be determined from at least two antennas according to the receiving performance of each antenna.
In this embodiment, one way to determine the transmitting antenna from at least two antennas is: determining the antenna with the optimal receiving performance as a transmitting antenna, wherein the optimal receiving performance means that the receiving performance of the antenna determined as the transmitting antenna is better than the receiving performance of other antennas which are not determined as the transmitting antenna, so that the determined transmitting performance of the transmitting antenna is optimal, and the wireless signal is favorably transmitted.
Or in this embodiment, one way to determine the transmitting antenna from at least two antennas is: and randomly selecting one antenna as a transmitting antenna according to the receiving performance of each antenna, for example, filtering out the antenna with the worst receiving performance according to the receiving performance of each antenna, and then randomly selecting one antenna from the rest of the plurality of antennas as the transmitting antenna, wherein the worst receiving performance means that the receiving performance of the antenna is lower than the receiving performance of the rest of the antennas.
The points to be explained here are: in the signal transmission control method of this embodiment, the receiving performance of each antenna can be determined in each receiving time slot, and then the transmitting antenna can be determined according to the receiving performance of each antenna in the transmitting time slot, so as to optimize the transmitting performance of each transmitting time slot, but it should be noted that the receiving performance according to which any transmitting time slot determines the transmitting antenna is: the receiving time slot which is positioned before the transmitting time slot and is adjacent to the transmitting time slot determines the receiving performance.
203: the wireless signal is transmitted through a transmit antenna.
According to the technical scheme, the receiving performance of each antenna in at least two antennas corresponding to the terminal is determined, the transmitting antenna is determined from the at least two antennas according to the receiving performance of each antenna in the at least two antennas, and the wireless signal is transmitted through the transmitting antenna. Each antenna receives wireless signals and transmits wireless signals by adopting the same frequency band, so that the receiving performance and the transmitting performance of each antenna are the same, the transmitting antenna can be determined from at least two antennas corresponding to the terminal according to the receiving performance of each antenna, and the transmitting antenna can be flexibly selected according to the receiving performance of the antenna. In addition, the receiving performance of each antenna is determined once in each receiving time slot, and then the transmitting antenna can be adjusted according to the receiving performance of each antenna in each transmitting time slot, so that the receiving performance of each transmitting time slot is optimized.
Referring to fig. 3, another flow chart of a signal transmission control method according to an embodiment of the present invention is shown, which may include the following steps:
301: and determining the receiving performance of each antenna in at least two antennas corresponding to the terminal, wherein each antenna respectively receives wireless signals and transmits wireless signals by adopting the same frequency band.
302: and determining a transmitting antenna from the at least two antennas according to the receiving performance of each antenna of the at least two antennas.
Wherein step 301 and step 302: like the above steps 201 and 202, this embodiment will not be explained. In this embodiment, the receiving performance of each antenna is determined once in each receiving slot, and then the transmitting antennas can be adjusted according to the receiving performance of each antenna in each transmitting slot, so as to optimize the receiving performance of each transmitting slot.
303: and controlling communication link connection between the transmitting port of the terminal and the transmitting antenna. That is to say, the communication link between the transmitting port of the terminal and each antenna is in a disconnected state, and when the transmitting antenna is determined according to the receiving performance of each antenna, the communication link between the transmitting port and the transmitting antenna is connected, and the communication link between the transmitting port and the other antenna which is not used as the transmitting antenna is still maintained in the disconnected state, so that only the communication link between the transmitting port and the transmitting antenna occupies the system resource at each time, and the occupation of the system resource can be reduced.
In this embodiment, one way to control communication link communication between the transmitting port and the transmitting antenna of the terminal is as follows: the link control component in the control terminal is connected with the transmitting port and the transmitting antenna, and the link control component is controlled to disconnect the transmitting port and other antennas except the transmitting antenna in the at least two antennas, so that only the communication link between the transmitting port and the transmitting antenna is connected in a transmitting stage (such as a transmitting time slot).
Taking 4 antennas corresponding to a terminal as an example, a link control component is arranged on a communication link between a transmitting port of the terminal and the 4 antennas, the link control component divides the communication link between the transmitting port and each antenna into two sections, and the link control component makes the two sections of each communication link in a separated state at other stages of a transmitting stage, so that the communication link between the transmitting port of the terminal and each antenna is in a disconnected state. If the first end of the link control component is connected with the transmitting port, the second end to the fifth end of the link control component are respectively connected with one antenna, and the antennas connected from the second end to the fifth end are different, the first end and the second end to the fifth end of the link control component are not connected in other stages of the transmitting stage, so that the communication link between the transmitting port of the control terminal and each antenna is in a disconnected state.
In the transmitting stage, the first end in the link control part is connected with the end corresponding to the communication link of the transmitting antenna, so that the communication link between the transmitting port and the transmitting antenna is connected, and the first end is not connected with other ends, so that other communication links are still in a disconnected state.
Of course, in the case that one link control unit is disposed on the communication link, the number of ends of the link control unit connected to the antennas may be greater than the total number of antennas, or in this embodiment, a plurality of link control units may be disposed on the communication link, and each link control unit controls the state of at least one communication link, which is not described again in this embodiment.
304: the wireless signal is transmitted to the transmit antenna via the transmit port and the communication link.
305: the wireless signal is transmitted through a transmit antenna.
According to the technical scheme, under the condition that the transmitting antenna is determined, the communication link between the transmitting port of the control terminal and the transmitting antenna is communicated, and the communication link between the transmitting port and other antennas which are not used as the transmitting antenna is still maintained in a disconnected state, so that only the communication link between the transmitting port and the transmitting antenna occupies system resources each time, and the occupation of the system resources is reduced.
While, for purposes of simplicity of explanation, the foregoing method embodiments have been described as a series of acts or combination of acts, it will be appreciated by those skilled in the art that the present invention is not limited by the illustrated ordering of acts, as some steps may occur in other orders or concurrently with other steps in accordance with the invention. Further, those skilled in the art should also appreciate that the embodiments described in the specification are preferred embodiments and that the acts and modules referred to are not necessarily required by the invention.
Corresponding to the foregoing method embodiment, an embodiment of the present invention further provides a terminal, where the structure of the terminal is shown in fig. 4, and the terminal may include: the wireless communication device comprises a processor 11 and at least two antennas 12, wherein each antenna 12 of the at least two antennas 12 respectively receives wireless signals and transmits wireless signals by using the same frequency band. That is to say, for any one of the at least two antennas corresponding to the terminal: the antenna uses the same frequency band to receive wireless signals and transmit wireless signals, and the frequency band used by the antenna may be different from the frequency bands used by other antennas.
And the processor 11 is configured to determine a receiving performance of each of the at least two antennas, determine a transmitting antenna from the at least two antennas according to the receiving performance of each of the at least two antennas, and transmit a wireless signal through the transmitting antenna.
In this embodiment, one way for processor 11 to determine the reception performance of each antenna is: the signal strength of each antenna is determined, and the reception performance of each antenna is determined according to the signal strength of each antenna. If the signal strength is stronger, the receiving performance is better, so that the signal strength of each antenna can be sorted, and if the signal strength is sorted from high to low, the obtained sorting result can indicate the receiving performance of all antennas corresponding to the terminal, or a corresponding relation between the signal strength and the receiving performance is preset, and under the condition that the signal strength of each antenna is determined, the receiving performance of each antenna can be obtained according to the corresponding relation. The signal strength of each antenna may be determined during a receiving time slot (i.e., when receiving a wireless signal), for example, as to the manner of determining the signal strength of each antenna and other manners of determining the receiving performance of each antenna, which is not described in detail in this embodiment.
Since any one antenna corresponding to the terminal can receive and transmit wireless signals in the same frequency band, so that the receiving performance and the transmitting performance of the antenna are the same, the processor 11 can determine the transmitting antenna from at least two antennas according to the receiving performance of each antenna.
In this embodiment, one way to determine the transmitting antenna from at least two antennas is: determining the antenna with the optimal receiving performance as a transmitting antenna, wherein the optimal receiving performance means that the receiving performance of the antenna determined as the transmitting antenna is better than the receiving performance of other antennas which are not determined as the transmitting antenna, so that the determined transmitting performance of the transmitting antenna is optimal, and the wireless signal is favorably transmitted.
The points to be explained here are: the processor 11 may determine the receiving performance of each antenna in each receiving time slot, and then determine the transmitting antenna according to the receiving performance of each antenna in the transmitting time slot, so as to optimize the transmitting performance of each transmitting time slot, but it should be noted that the receiving performance according to which any transmitting time slot determines the transmitting antenna is: the receiving time slot which is positioned before the transmitting time slot and is adjacent to the transmitting time slot determines the receiving performance.
The processor 11 is further configured to control communication link communication between the transmitting port of the terminal and the transmitting antenna, and transmit the wireless signal to the transmitting antenna via the transmitting port and the communication link. That is to say, the communication link between the transmitting port of the terminal and each antenna is in a disconnected state, and when the transmitting antenna is determined according to the receiving performance of each antenna, the communication link between the transmitting port and the transmitting antenna is connected, and the communication link between the transmitting port and the other antenna which is not used as the transmitting antenna is still maintained in the disconnected state, so that only the communication link between the transmitting port and the transmitting antenna occupies the system resource at each time, and the occupation of the system resource can be reduced.
The structure of the terminal controlled by the corresponding communication link is shown in fig. 5, and on the basis of fig. 4, the structure may further include: and a link control section 13 provided between the transmission port of the terminal and the at least two antennas. The processor 11 is configured to control the link control unit to connect the transmitting port and the transmitting antenna, and control the link control unit to disconnect the transmitting port and the other antennas except the transmitting antenna, so that only the communication link between the transmitting port and the transmitting antenna is connected.
Referring to fig. 6, in fig. 6, 4 antennas are ANT1 to ANT4, Tx is a transmitting port, Rx1 to Rx4 are receiving ports, a first end of the link control unit 13 is connected to the transmitting port Tx, second to nth ends of the link control unit 13 are connected to one antenna, and the antennas connected to the second to nth ends are different, where (n-1) is equal to the total number of antennas, that is, the number of the ends of the link control unit 13 for connecting the antennas may be the same as the total number of antennas, so that each antenna is connected to one end of the link control unit 13, but the number of the other ends of the link control unit 13 except the first end may be greater than the total number of antennas.
For the link control unit 13 shown in fig. 6, in a case where it is determined that the antenna connected to the i-th end (where i takes a value of 2 or more and n or less) of the link control unit 13 is the transmitting antenna, the processor 11 may control the first end to be connected to the i-th end so that the communication link between the transmitting port and the transmitting antenna is connected, and control the first end and the ends other than the i-th end among the second end to the n-th end to be in a disconnected state so that the communication link between the transmitting port and the other antennas is in a disconnected state, for example, if the antenna ANT1 is the transmitting antenna in fig. 6, the first end is connected to the end of the link control unit 13 connected to the antenna ANT 1. In practical applications, a power amplifier may be further connected between the transmitting port and the first end of the link control unit 13 for amplifying the wireless signal to facilitate the transmission of the wireless signal.
According to the technical scheme, the receiving performance of each antenna in at least two antennas corresponding to the terminal is determined, the transmitting antenna is determined from the at least two antennas according to the receiving performance of each antenna in the at least two antennas, and the wireless signal is transmitted through the transmitting antenna. Each antenna receives wireless signals and transmits wireless signals by adopting the same frequency band, so that the receiving performance and the transmitting performance of each antenna are the same, the transmitting antenna can be determined from at least two antennas corresponding to the terminal according to the receiving performance of each antenna, and the transmitting antenna can be flexibly selected according to the receiving performance of the antenna. In addition, under the condition that the transmitting antenna is determined, the communication link between the transmitting port of the terminal and the transmitting antenna is controlled to be connected, and the communication link between the transmitting port and other antennas which are not used as the transmitting antenna is still maintained in a disconnected state, so that only the communication link between the transmitting port and the transmitting antenna occupies system resources at each time, and the occupation of the system resources is reduced.
