Description

Antenna performance optimization method and device, terminal and computer readable storage medium

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an antenna performance optimization method and apparatus, a terminal, and a computer-readable storage medium.

Background

At present, more and more smart phones adopt an upper antenna and a lower antenna of a metal frame, and when the state of a hand holding or a certain antenna is poor, a double-pole double-throw switch (DPDT) is used for switching the antennas, so that the performance of the antennas is improved. However, the current rf front end has one path of transmitting TX and receiving PRX, and only the same antenna is used. In the GSM system, the radio interface employs a combination of Time Division Multiple Access (TDMA) and Frequency Division Multiple Access (FDMA). Users communicate on different frequency channels and each frequency channel (TRX) can be divided into 8 time slots, one for each channel. For the reason that GSM transmission and reception are not at the same frequency, one antenna has good transmission efficiency and is not necessarily good in reception efficiency, the same antenna is used for transmission and main reception, so that antenna performance cannot be sufficiently optimized, and GSM transmission and reception are not performed simultaneously, and are divided into a transmission TX time slot and a reception RX time slot for the same user.

The current antenna switching method is also only used in some situations, such as when the lower antenna signal is bad, the antenna for signal transmission/reception is switched to the upper antenna, the antenna switching method still adopts the antenna control method in the GSM system, namely, in the GSM system, signal transmission and signal reception are carried out on the same antenna within a period of time, but since the use of Frequency Division Multiple Access (FDMA) in GSM systems results in the transmitted signal not being the same frequency as the received signal, the performance of the same antenna in a signal transmitting state and the performance of the same antenna in a signal receiving state are different, the performance of the antenna is off-shelf, the advantages of multiple antennas cannot be exerted, and aiming at the problem, the antenna performance is optimized.

First embodiment

Fig. 3 is a basic flowchart of an antenna performance optimization method provided in this embodiment, where the antenna performance optimization method includes:

s301, identifying a target communication time slot.

And after the terminal is connected into the GSM communication system, identifying the current target communication time slot of the terminal.

And matching a corresponding target communication antenna according to the target communication frequency and the corresponding relation between the communication frequency and the antenna.

And S304, switching to a target communication antenna.

And switching the antenna currently connected with the terminal to the target communication antenna.

In this embodiment, a target communication slot in which a terminal is currently located is identified, where the target communication slot includes: a transmit TX slot or a receive RX slot.

GSM is an abbreviation of Global System For Mobile Communications, a digital Mobile communication standard formulated by the european telecommunication standards institute ETSI, GSM is a short term For Global System For Mobile Communications, and a radio interface of GSM adopts a combination of Time Division Multiple Access (TDMA) and Frequency Division Multiple Access (FDMA).

Frequency Division Multiple Access (FDMA) is one of the most mature multiple access multiplexing modes, and a Frequency Division Multiple Access (FDMA) addressing mode is adopted, wherein a system central station is provided with N channels, and each channel corresponds to a central carrier frequency; all remote station communication time slots TS (time slot) can share the channel resources of the central station, that is, the TS can operate on any carrier frequency channel under the control of the central station; frequency Division Multiple Access (FDMA) is characterized by mature technology, stability, easy implementation and low cost. Its main disadvantage is that the spectrum utilization is low, each user (remote station) occupies a certain frequency band, and especially under the condition of limited air bandwidth resources, the Frequency Division Multiple Access (FDMA) system can encounter difficulty in organizing a multi-sector base station. The Frequency Division Multiple Access (FDMA) is rarely adopted as a multiple access method, and a Time Division Multiple Access (TDMA) method or a combination of the TDMA and the FDMA is mostly adopted in practical systems.

Time Division Multiple Access (TDMA) is a channel composed of continuous periodic time slots, different signals are distributed into different time slots, a system central station broadcasts and transmits user data according to time slot arrangement (TDM), all communication time slots TS can be received, data transmitted to the system central station are taken out according to address information, and downlink transmission uses a carrier frequency; all communication time slots TS share the uplink carrier frequency, and under the control of the central station, data is burst to the central station according to the time slot allocated to the central station. Time Division Multiple Access (TDMA) is widely used in the field of broadband wireless access because of its high spectrum utilization compared to Frequency Division Multiple Access (FDMA).

For example, 8 users are all in the same operating frequency, and as viewed from the frequency division multiple access system, they cannot operate simultaneously, and only after one user operates, another user can operate, otherwise, co-channel interference is caused. However, if the time division multiple access method is adopted, the T0 time slot is allocated to the first user, or the first user is separated by T1-T7 time slots after the time frames 1 to T0, and operates at T0 time slot of time frame 2. By analogy, assign T1 slot to the second user task … … assigns the T7 slot to the eighth user. By using the time-sharing multiplexing mode, users with the same frequency can work at the same time, frequency resources are effectively utilized, and the capacity of the system is improved. For example, the total frequency band of a system is divided into 124 frequency channels, and if only the FDMA mode is available, only 124 channels are available. If Frequency Division Multiple Access (FDMA) is used, and each frequency channel accommodates 8 time slots, the total capacity of the system channel is 124 × 8 — 992 channels.

In this embodiment, the GSM communication system adopts a combination of Time Division Multiple Access (TDMA) and Frequency Division Multiple Access (FDMA). The users communicate on different frequency channels, and each frequency channel (TRX) can be divided into 8 time slots, each time slot is a channel, for GSM transmitting and receiving are not different frequencies, an antenna has good transmitting efficiency and not necessarily good receiving efficiency, and GSM transmitting and receiving are not simultaneously carried out, and the same user is divided into transmitting TX time slot and receiving RX time slot. Therefore, when a user is in the GSM communication system, the same time value will only be in one time slot including: in the transmission TX time slot or the reception RX time slot, the communication frequencies of adjacent communication time slots may be different, and the communication frequencies of the same communication time slot may also be different.

When the target communication time slot is a transmitting TX time slot, acquiring the frequency to be transmitted of a signal to be transmitted; matching a target transmitting antenna corresponding to the frequency to be transmitted according to the corresponding relation between the preset transmitting frequency and the transmitting antenna; and switching the antenna connected currently to the target transmitting antenna.

Referring to fig. 4, fig. 4 is a flowchart of a terminal in a TX slot, including:

s401, the terminal recognizes that it is in a TX slot for transmission.

S402, acquiring the transmitting frequency of the transmitting TX time slot.

And S403, matching a target transmitting antenna corresponding to the transmitting frequency.

And S404, switching the currently connected antenna to a target transmitting antenna.

When the target communication time slot is a receiving RX time slot, acquiring the frequency to be received of the signal to be received; matching a target receiving antenna corresponding to the frequency to be received according to the corresponding relation between the preset receiving frequency and the receiving antenna; and switching the currently connected antenna to the target receiving antenna.

Referring to fig. 5, fig. 5 is a flowchart of the terminal when receiving an RX timeslot, including:

s401, the terminal recognizes that it is in a receiving RX slot.

S402, acquiring the receiving frequency of the receiving RX time slot.

And S403, matching a target receiving antenna corresponding to the receiving frequency.

And S404, switching the currently connected antenna to the target receiving antenna.

In this embodiment, there is further provided a matching relationship between the transmitting/receiving frequency and the transmitting/receiving antenna, where the preset corresponding relationship between the transmitting/receiving frequency and the transmitting/receiving antenna includes: respectively transmitting/receiving signals of the same frequency through each transmitting/receiving antenna, detecting the transmitting/receiving efficiency of each antenna for transmitting/receiving the signals of the same frequency, and corresponding at least one transmitting/receiving antenna with the highest transmitting/receiving efficiency and the transmitting/receiving signals of the frequency into a group. In practical applications, due to the differences in antenna design, the performance of the antenna for transmitting/receiving signals in different frequency bands is different, in current terminals, in order to ensure good signal experience, multiple antennas are usually designed to satisfy the transmission/reception of signals in different frequency bands, and therefore, when determining the matching relationship between the communication frequency and the antennas, each antenna can transmit/receive signals of different transmitting/receiving frequencies, respectively detect the performance of each antenna in transmitting/receiving signals of different frequencies, respectively, match at least one antenna with the highest performance with the corresponding transmitting/receiving frequency into a group, therefore, after the transmitting/receiving frequency is obtained, the corresponding antenna with the best energy efficiency can be matched to transmit/receive signals, and the optimization of the antenna performance of the terminal is improved.

In this embodiment, the GSM communication network uses a combination of Time Division Multiple Access (TDMA) and Frequency Division Multiple Access (FDMA), where only one communication time slot exists at a time, i.e. the transmitting TX time slot and the receiving RX time slot cannot exist simultaneously, and uses Frequency Division Multiple Access (FDMA), the transmitting/receiving frequencies of two adjacent time slots may be different, and considering the size of the signal antenna, the transmitting antenna and the receiving antenna may share one antenna in many cases. Thus, the transmit antenna and the receive antenna may be the same day, or different antennas.

In this embodiment, when determining the matching relationship between the transmitting/receiving frequency and the antenna, there may be multiple antennas with optimal energy efficiency at the same transmitting/receiving frequency, and in this case, in order to further improve the performance of the antenna, multiple transmitting/receiving antennas may be connected together, so as to further improve the performance of the antenna.

This embodiment (advantageous effects).

The embodiment provides an antenna performance optimization method, which comprises the following steps: identifying a target communication time slot in which a terminal is currently located; acquiring target communication frequency according to the target communication time slot; matching a corresponding target communication antenna according to the target communication frequency and the corresponding relation between the communication frequency and the antenna; and switching the antenna connected currently to the target communication antenna. The energy efficiency ratio of the antenna in the GSM communication system is improved by detecting each communication time slot and the signal frequency of the time slot in the GSM communication system and respectively matching the antenna corresponding to the signal frequency.

According to the obtained receiving frequency, a receiving antenna corresponding to the receiving frequency is matched from the database, and the receiving antenna generally has better receiving performance for the receiving signal of the frequency, for example, when the antenna receives the receiving signal of the frequency, the performance of the received signal-to-noise ratio is better, the receiving efficiency is higher, and the like.

And S623, switching to a corresponding receiving antenna.

After the antenna with the best receiving performance is matched, an antenna switch is switched to the antenna with the best receiving performance, when the matched antenna comprises a plurality of antennas, one receiving antenna can be selected from the antennas according to a preset rule, for example, the antenna with the closest distance can be selected according to the distance, or the antenna is selected according to the holding gesture of a user, and when the user holds the lower end of the smart phone, the antenna positioned at the upper end of the smart phone is selected; it is also possible to connect multiple receiving antennas simultaneously.

When the communication time slot is identified as a transmitting TX time slot, acquiring the transmitting frequency of the signal to be transmitted.

And S622, matching the corresponding transmitting antenna.

According to the acquired transmitting frequency, a transmitting antenna corresponding to the transmitting frequency is matched from the database, and the transmitting antenna generally has better transmitting performance for the transmitting signal of the frequency, for example, when the antenna transmits the transmitting signal of the frequency, the signal-to-noise ratio performance of the transmission is better, the transmitting efficiency is higher, the transmitting gain is higher, and the like.

And S623, switching to a corresponding transmitting antenna.

After the antenna with the best transmission performance is matched, an antenna switch is switched to the antenna with the best transmission performance, when the matched antenna comprises a plurality of antennas, one receiving antenna can be selected from the antennas according to a preset rule, for example, the antenna with the closest distance can be selected according to the distance, or the antenna can be selected according to the holding gesture of a user, and when the user holds the lower end of the smart phone, the antenna positioned at the upper end of the smart phone is selected; multiple transmit antennas may also be connected simultaneously.

It should be noted that, after step S613 in fig. 6, step S621 is directly performed, and after step S623, step S611 is directly performed, which is only one embodiment, in a general case, both the TX timeslot and the RX timeslot are crossed, that is, one TX timeslot is followed by one RX timeslot, so that the identification process of the next communication timeslot can be omitted after completing the step of one TX timeslot or one RX timeslot, and the next communication timeslot is directly entered, which can reduce the flow of the antenna performance optimization method, improve the efficiency of antenna performance optimization, reduce the power consumption of the smart phone in antenna performance optimization, and improve the user experience. Meanwhile, in order to ensure the conversation quality and the accuracy of identifying the communication gap, the type of the communication time slot can be identified again after each TX time slot is transmitted or RX time slot is received.

It should be noted that, in this embodiment, the matching relationship between the transmitting/receiving frequency and the transmitting/receiving antenna is built in the storage, and the matching relationship between the transmitting/receiving frequency and the transmitting/receiving antenna is already determined after the smart phone is designed, and the modification is usually performed only by the system server, but in some cases, the modification may be performed by the user. After the transmitting/receiving frequency is obtained, the smart phone matches the corresponding transmitting/receiving antenna from the data stored in the storage.

It is worth noting that, in a smart phone, because the volume of the antenna is limited, the transmitting antenna and the receiving antenna are usually integrated on one antenna, that is, one antenna has both functions of signal transmission and signal reception, and therefore, in the matched result, the transmitting antenna and the receiving antenna can be the same antenna.

This embodiment (advantageous effects).
