Technical field

The present disclosure relates to the field of communications technologies, and in particular, to an antenna beam detecting system, method, and mobile terminal.

Background technique

Because of the popularity of intelligent mobile terminals increasingly high, with the fifth generation (5 ^th Generation, 5G) gradually coming era of mobile communications and wireless high-speed transmission applications are increasingly sophisticated, it should be due to high-speed wireless transmission while The demand for increased transmission frequency is obvious, so the wireless communication system in the millimeter band has increasingly become one of the trends and hot spots in the industry.

Applications for wireless high-speed transmission include Wireless Gigabit (WiGig)/802.11ad, or Wireless High Definition (Wireless HD) transmission technology.

In the millimeter wave band, in order to maintain good wireless communication quality, antennas often need to be designed in an array form (ie, a scheme consisting of multiple (at least two or more) antenna arrays to form a single port) to have higher antenna gain. To resist the high attenuation of the high frequency (millimeter wave) propagation path, but since the high gain due to the formation of the array is accompanied by a narrow beamwidth, the array is required to have both beam steering or beamforming. The ability to achieve a wide range of wireless transmission coverage to have a better user wireless communication experience.

However, because the millimeter wave is more sensitive to the outside than the communication frequency band commonly used in current handheld mobile terminals, the wireless communication performance is significantly degraded, and the user's wireless communication experience is greatly degraded. Therefore, in an increasingly evolved mobile terminal, the antenna array of the millimeter wave band is often not only a single one, but at least two or more switches between modules to be used in various user handheld scenes (such as horizontal or vertical screen). ) or placement of the scene (such as put the screen up or put the screen down) can have good wireless communication coverage, and have a good user wireless communication experience. The occlusion of the millimeter wave to the outside may be: the antenna array module of the handheld mobile terminal is held or covered by the user, or placed on an iron table, or an object or a human body blocks the signal source (hot spot) and the terminal. Light of sight (LOS) on a straight path.

As mentioned above, most of the current switching mechanisms between millimeter-wave modules are often based on the signal strength of the received wireless communication signal source (and can be added with a pre-designed period of observed signal strength, but not necessarily) and in the system. The threshold of the preset switching of the software algorithm is compared as the basis for switching the module, but since the switching mode takes a long time, in the scenario of wireless high-speed transmission, if there is an antenna module in use Due to coverage or occlusion, it is often necessary to switch to another module, and thus there will be a large amount of data, thus demodulating errors or loss, and even communication disconnection, which greatly affects the user's wireless communication experience.

When the detection result is: the antenna array is not occluded, the working state of the current RF module is maintained.

Embodiments of the present disclosure also provide a solution for performing information interaction between a mobile terminal and a base station and determining a detection result. The base station and the terminal can agree on the knowledge of the radio module to be switched, thereby ensuring that the radio module (antenna/beam/antenna panel) is correctly selected in the uplink transmit antenna selection transmission mode, and the uplink power control process is quickly and accurately adjusted. The uplink transmit power of the terminal radio module. The following describes the flow of information exchange between the mobile terminal and the base station.

First, the mobile terminal needs to establish a connection with the base station, and report the capability information of the mobile terminal to the base station. In this embodiment, the capability information of the mobile terminal to detect the antenna beam path needs to be added on the basis of the existing mobile terminal capability information. The information may be added to the existing mobile terminal capability list, or a parameter option may be added to the mobile terminal capability category, where the content of the newly added parameter option corresponds to the capability information of the mobile terminal detecting the antenna beam path.

When the mobile terminal base station reports the mobile terminal capability information, it can be classified or reported.

When the classification report is performed, the capability information of the mobile terminal to detect the antenna beam path is determined as the first type of capability information, and the capability information in the existing protocol is determined as the second type of capability information. The RRC connection is controlled by the RRC, and the first type of capability information of the mobile terminal to detect the antenna beam path is reported to the base station; after the RRC connection is established and the query information sent by the base station is received, the second type of capability information of the mobile terminal is reported to the base station. .

When the first type of capability information is reported by the radio resource control (RRC) connection (the random access procedure), the first type of capability information may be carried in the uplink message in the random access process. The uplink information may be a random access preamble or an RRC connection request in a random access procedure. When the second type of capability information is reported, it may be carried in a message that the mobile terminal returns to the base station in response to the query information.

When the RRC connection is established and the query information sent by the base station is received, the mobile terminal detects the first type of capability information of the antenna beam path and the second type of capability information of the mobile terminal, and reports the capability information to the base station. This part of the information may be carried in a message that the mobile terminal returns to the base station in response to the inquiry information.

After the capability information is reported, the configuration information that is sent by the base station in the connected state by using the RRC signaling is included, where the configuration information includes a first instruction that allows the mobile terminal to detect autonomously or a second instruction that allows the mobile terminal to autonomously detect and switch. .

For the first instruction:

When the first instruction is included in the configuration information, the step of acquiring an attribute parameter of the echo signal of the probe antenna according to the first instruction, and obtaining the detection result according to the attribute parameter and the preset parameter is performed. After the detection result is obtained, the detection result is reported to the base station. When the detection result is reported, the two types of reporting modes, that is, periodic reporting and aperiodic reporting, are required. The detection result is reported to the base station according to the reporting period of the network configuration. The detection result may be that the antenna array is blocked or the antenna array is unoccluded.

When the detection result is that the antenna array is occluded, the detection result is reported to the base station. In the state where the antenna array is occluded, the detection result is reported to the base station, and the antenna can be reported to the base station. The identification information of the RF module that is blocked by the array and the identification information of the recommended RF module to be switched.

For the non-periodic reporting result, the identification information of the RF module that is blocked by the antenna array and the identification information of the RF module to be switched recommended by the mobile terminal can be sent to the base station at the same time, and the base station can obtain related information of the current mobile terminal. The non-periodic reporting resource may be the latest uplink channel resource after the detection result is obtained.

When the detection result is that the antenna array is occluded, the base station returns a reply message to the mobile terminal, where the reply information includes at least: triggering the radio module switching information, the target radio module identification information to be switched, and the uplink power control adjustment step information. . The target radio frequency module that the base station replies to the mobile terminal may be a radio frequency module recommended by the mobile terminal, or may be a radio frequency module selected by the base station itself.

After receiving the reply information fed back by the base station, the mobile terminal performs handover of the target radio frequency module according to the reply information, and performs uplink power control adjustment. That is, the mobile terminal triggers the handover operation according to the reply information, and switches to the target radio frequency module, and the mobile terminal performs uplink power control adjustment.

After receiving the reply information, the mobile terminal may report the handover result to the base station according to the period configured by the network; or report the handover result to the base station after the target radio module is switched.

That is, the method of reporting the result of the handover includes periodic reporting and aperiodic reporting. For periodic reporting, there are two kinds of reported results. The target RF module is switched over or not completed. For non-periodic reporting, only after the handover is completed. The reporting, where the reported resource may be the latest uplink channel resource after the handover.

For the second instruction:

When the second instruction is included in the configuration information, performing the step of acquiring an attribute parameter of the echo signal of the probe antenna according to the second instruction, and obtaining a detection result according to the attribute parameter and the preset parameter; when the detection result is that the antenna array is blocked The switching of the target radio frequency module is performed, and the handover result is reported to the base station according to the reporting period set by the network or the handover result is reported to the base station after the handover is completed.

When the second instruction is executed, after determining that the antenna array is occluded, the target RF module is switched. For the handover, the process corresponding to the reporting of the handover result may be periodic reporting or non-periodic reporting. When the periodic report is performed, the result is reported to the base station according to the reporting period set by the network. The corresponding switching result is two, that is, the handover succeeds or the handover is successful. When the aperiodic report is performed, the report is reported only after the handover is completed. The resource that is reported may be the latest uplink channel resource after the handover.

For the communication process between the mobile terminal and the base station, after acquiring the detection result, the mobile terminal may report the detection result to the base station, so that the base station acquires the detection result and performs handover according to the indication of the base station. After obtaining the detection result, the mobile terminal may also determine the target radio frequency module to be switched to directly switch the target radio frequency module.

The above is the interaction process between the mobile terminal and the base station in the embodiment of the present disclosure, that is, the software program part corresponding to the embodiment of the present disclosure. At the software level, a specific protocol and algorithm can be designed to avoid unnecessary fast and frequent between multiple RF modules. Over-switching or mis-switching to reduce system power consumption and improve wireless communication quality to optimize the user experience.

In order to avoid unnecessary fast and frequent switching or incorrect switching between multiple radio frequency modules, the embodiments of the present disclosure provide the following manners.

When acquiring the target echo amplitude and phase of the echo signal, the timer and/or counter can be set according to network configuration and protocol conventions. When the timer is set, the target echo amplitude and phase of the echo signal can be counted multiple times in a period of time; the target echo amplitude and phase of the acquired multiple echo signals are averaged to obtain multiple target echoes. The average of the amplitude and the phase, and then compare the obtained average value with the preset echo amplitude and phase to obtain the difference between the two, and determine whether the difference between the two is within the set difference range, and if so, prove Currently, the antenna array of the first radio frequency module is blocked, and the radio frequency module needs to be switched at this time.

When the counter is set, the target echo amplitude and phase of the statistical echo signal can be accumulated, and after reaching the set number of times, the average of the amplitude and phase of the plurality of target echoes is obtained, and then the obtained average value and the preset value are obtained. The amplitude of the wave is compared with the phase, and the difference between the two is obtained. It is judged whether the difference between the two is within the set difference range. If it is, the antenna array of the first RF module is occluded, and the RF module needs to be switched. .

For the case where the timer and the counter are set at the same time, the preset number of target echo amplitudes and phases can be acquired for a period of time, and then the average value is calculated, and details are not described herein again. The following process of the present disclosure is described by taking a timer and counting the target echo amplitude and phase of the echo signal multiple times over a period of time.

When it is determined that the antenna array of the first radio frequency module is occluded, the radio frequency module switching is required. After switching to the second radio frequency module, the antenna beam detection method provided by the embodiment of the present disclosure is required to determine the echo signal of the detecting antenna. The amplitude and phase of the target echo are used to count the average of the amplitude and phase of the multiple echoes over a period of time, and compare with the amplitude and phase of the preset echo to obtain the sensing result of whether the current RF module is occluded.

If the number of the radio frequency modules included in the mobile terminal is two, and the antenna array of the switched second radio frequency module is still blocked, the current antenna array of the first radio frequency module may be viewed, if the antenna of the first radio frequency module When the array is unoccluded, the antenna module can be switched back to the first radio frequency module. If the antenna array of the first radio frequency module is still blocked, the occlusion degree of the antenna array of the first radio frequency module and the second radio frequency module can be obtained. When the antenna array of the module is blocked to a much higher degree than the second RF module, the second RF module can be maintained. If the antenna array of the first RF module is blocked to a much lower extent than the second RF module, the switch can be switched. To the first RF module. If the antenna array of the first RF module is occluded to a degree similar to the occlusion of the antenna array of the second RF module, the second RF module can be maintained. If the first RF module and the second RF module are occluded, if there is still no improvement after waiting for a period of time, the synchronization signal and the broadcast message may be re-listed until the network is re-entered.

If the mobile terminal includes multiple radio frequency modules (for example, three), the antenna array of the switched second radio frequency module is still blocked, and can be switched to the third radio frequency module, after switching to the third radio frequency module, An antenna beam detection method according to an embodiment of the present disclosure is needed to determine a target echo amplitude and phase of a probe antenna echo signal, and a mean value corresponding to a plurality of target echo amplitudes and phases is counted for a period of time, and a preset echo is used. The amplitude is compared with the phase to obtain a sensing result of whether the current RF module is occluded.

If the three RF modules are occluded, you can compare the extent to which the three RF modules are occluded, and determine the difference between the target echo amplitude and the phase of the RF module with the most occlusion and the least occlusion. When the threshold is exceeded, switch to the RF module with the least occlusion.

If all three RF modules are occluded, you can listen to the sync and broadcast messages again until you re-enter the network.

The method for applying to the mobile terminal provided by the embodiment of the present disclosure can quickly detect the influence of the external environment on the antenna array, obtain the detection result of whether the antenna array is blocked, and adjust according to the detection result to reduce the sense of switching of the RF module. The measurement time ensures the accuracy and integrity of the data transmission, thereby ensuring the transmission effect of the wireless communication and improving the wireless communication experience of the user.
