Technical field

The present disclosure relates to the field of communications technologies, and in particular, to an antenna beam switching sensing 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 more sophisticated, and therefore, application to high-speed wireless transmission, The demand for its transmission frequency is increasing, and the wireless communication system in the millimeter wave band has increasingly become one of the trends and hot spots in the industry. Wireless high-speed transmission applications 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, the antenna often needs to be designed in an array form (ie, a scheme consisting of multiple (at least two or more) antenna units forming a single port) to have a higher antenna gain. To resist the high attenuation of the high frequency (millimeter wave) propagation path. However, 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 to achieve a wide spatial coverage of wireless transmission. 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 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 the screen facing up or the screen facing down) can have good wireless communication coverage, so that there is a good user wireless communication experience. The occlusion of the millimeter wave to the outside can 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 described above, the mechanism for switching between millimeter-wave modules in the related art is often based on the signal strength of the received wireless communication signal source (and a period of time in which a pre-designed observed signal strength can be added, but not necessarily) and the system The threshold of the preset switching of the software algorithm is compared as the basis for switching the module. However, since the switching mode takes a long time, in the case of wireless high-speed transmission, if an antenna module being used is covered or blocked, and then needs to be switched to another module, a large amount of data is often demodulated. Errors or churns, and even communication disconnection, greatly affecting the user's wireless communication experience.

When the classification report is performed, the capability information of the mobile terminal sensing antenna beam switching is determined as the first type of capability information, and the capability information in the protocol in the related art is determined as the second type of capability information. The first type of capability information of the mobile terminal sensing antenna beam switching is reported to the base station by using a radio resource control (RRC) connection; after the RRC connection is established and the query information sent by the base station is received, the second terminal of the mobile terminal is used. The class capability information is reported to the base station.

When the first type of capability information is reported through the RRC connection (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 first type of capability information of the antenna beam sensing and the second type of capability information of the mobile terminal are reported 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 using the RRC signaling in the connected state is received, where the configuration information includes a first instruction that allows the mobile terminal to autonomously sense or a second instruction that allows the mobile terminal to autonomously sense and switch. .

For the first instruction:

When the first instruction is included in the configuration information, the step of acquiring the attribute parameter of the echo signal of the antenna array according to the first instruction, and obtaining the sensing result according to the attribute parameter and the preset parameter is performed. After the sensing result is obtained, the sensing result is reported to the base station. When the sensing result is reported, the two reporting modes, that is, the periodic reporting and the aperiodic reporting, may be performed. The sensing result is reported to the base station according to the reporting period of the network configuration. The sensing result at this time may be that the antenna array is occluded, or the antenna array may be unoccluded.

In the case of aperiodic reporting, the sensing result is reported to the base station only when the sensing result is occluded by the antenna array. In the state where the antenna array is occluded, the sensing 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 aperiodic reporting result, the identification information of the radio frequency module in which the antenna array is occluded and the identification information of the radio frequency module to be switched recommended by the mobile terminal can be simultaneously sent to the base station, and the base station can obtain the related information of the current mobile terminal. The resource in which the aperiodic report is located may be the latest uplink channel resource after the sensing result is obtained.

When the sensing 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 antenna array according to the second instruction, and obtaining a sensing result according to the attribute parameter and the preset parameter; when the sensing result is that the antenna array is occluded 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 the antenna array is determined to be occluded, the switching of the target radio frequency module is performed. For the handover, the process corresponding to the reporting of the handover result may be a periodic report or an aperiodic report. 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 obtaining the sensing result, the mobile terminal may report the sensing result to the base station, so that the base station acquires the sensing result and performs switching according to the indication of the base station. After obtaining the sensing 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 setting a timer and counting the target echo amplitude and phase of the echo signal multiple times over a period of time.

When determining 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 unit echo is required to be determined according to the sensing method of the antenna beam path provided by the embodiment of the present disclosure. The target echo amplitude and phase of the signal are used to count the average of the amplitude and phase of the multiple echoes over a period of time, and compare with the preset echo amplitude and phase to obtain a 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, A sensing method of an antenna beam path according to an embodiment of the present disclosure is needed to determine a target echo amplitude and phase of an antenna unit echo signal, and a mean value of a plurality of target echo amplitudes and phases is counted for a period of time, and a preset The echo 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.
