detailed description

The present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.

As shown in FIG. 1 , this embodiment provides a downlink beam processing method, including:

Step S110: Detecting downlink beam quality of m beams in the scan area; the m is not small An integer of 2;

Step S120: Send first feedback information to the base station according to the downlink beam quality of the m beams, where the first feedback information is used by the base station to select, from the m beams, to send downlink information to the user equipment UE in the monitoring area. Beam

Step S130: Detecting downlink beam quality of n beams in the monitoring area according to downlink beam quality of the m beams, where n is a positive integer smaller than the m;

Step S140: Send second feedback information to the base station according to the downlink beam quality of the n beams, where the second feedback information is used by the base station to perform a predetermined operation.

The downlink beam processing method in this embodiment may be a method applied to the user equipment UE.

Both the scan area and the monitoring area may be in different time periods in the time dimension. One or more monitoring zones may be disposed between two adjacent scanning zones.

In this embodiment, the UE will detect the downlink beam quality of the m beams transmitted by the base station in the scanning area, where detecting the downlink beam quality may include: detecting information such as received signal strength or received energy of each of the m beams. . The m beams here may be all beams used by the base station for communication. Here, the m beams can be beams in different directions, the current location of the UE, some beams are undetectable, or the downlink beam quality is poor. The beams cannot be used for the base station to send downlink information to the UE, and the UE The movement is continuous, so the UE does not need to detect all the beams at all times. In view of this, in the monitoring area, based on the monitoring of the m beams, only n beams can be detected; the n is smaller than m, obviously In this way, the number of detection beams of the UE in the monitoring area is reduced, which reduces the power consumption of the UE for detecting the beam, thus prolonging the standby time of the UE. In the embodiment, the second feedback information may also include the n beam downlink beam qualities, which obviously reduces the amount of data relative to the downlink beam quality including m beams, reduces the information processing amount of the base station, and simplifies Information processing of the base station.

In this embodiment, the first feedback information is further used by the base station to select the n beams that are transmitted in the monitoring area from the m beams.

The first feedback information is further used by the base station to select, for the UE, to detect n beams, so that the base station can send n beams to the UE in the monitoring area, thereby reducing the number of the base station transmitting beams, and reducing the number. The power consumption of the base station reduces the overhead of downlink transmission. Certainly, in a specific implementation, the base station may determine, according to the first feedback information, an optimal beam for transmitting downlink information to the UE, where the base station still sends m beams in the monitoring area. However, the UE only detects n beams.

It is noted that: the first feedback information is sent by the UE to the base station, and the base station selects n beams based on the first feedback information, and after selecting the n beams, the optimal beam can be used to notify the UE, so that the UE can conveniently Monitoring of the beams. The base station may not notify the UE, and the UE selects n beams based on the first feedback information provided by the UE or the monitoring of the m beams, and may also know which n beams are detected by the monitoring area. Of course, if the base station only transmits n beams to the UE, the UE receives the n beams as much as possible.

The n beams include: an optimal beam, a target switching beam, and an alternate beam;

The optimal beam is a beam with the lowest downlink beam quality detected by the UE;

The target switching beam is a beam adjacent to the optimal beam in a moving direction of the UE; the target switching beam is or the optimal beam and the optimal beam in a moving direction of the UE The beam whose emission angle is within the preset orientation.

The spare beam is a beam with a predetermined spatial isolation from the optimal beam, and the downlink beam quality meets a preset condition.

The optimal beam may be at least one, and may be used for sending downlink information sent by the base station to the UE, where the downlink information may include various downlink information such as downlink control information, synchronization signal, system message, and downlink service information.

The target switching beam may be the optimal beam corresponding to the UE at the next moment. In this embodiment, the optimal beam is also selected according to the moving direction of the UE, so that the UE can perform n in the monitoring area. Beam detection, then in the current monitoring area, according to the UE in the previous monitoring area The detection of the downlink beam quality of the n beams performs switching between the optimal beam and the target switching beam in the current monitoring area.

In this embodiment, the spare beam is further included, where the spare beam may be a beam opposite to the optimal beam direction, or a beam whose transmission direction and the optimal beam's transmission direction satisfy a preset angle. In summary, the spare beam has a certain spatial isolation from the optimal beam, so that when the direction of propagation of the optimal beam receives occlusion or interference, a spare beam may be used instead of the optimal beam to transmit downlink information to ensure Smooth transmission of downstream information. The downlink beam quality of the spare beam meets a preset condition, which may include: the downlink beam quality of the spare beam is greater than a quality threshold, for example, the beam strength is greater than an intensity threshold; and, for example, the received power of the downlink beam of the spare beam is greater than a pre- Set the power threshold and so on.

Certainly, in a specific implementation process, the n beams include at least the optimal beam, and may include one of a target switching beam and/or a spare beam in addition to the optimal beam. In this embodiment, if the monitoring area includes a service area for performing service transmission, the optimal beam is also used for transmission of service information of the service area, or as a reference beam for the base station to send a reference signal to the UE. The reference beam can be used to adjust the beam for transmitting the service information according to the actual situation of the downlink transmission. The adjustment may include correcting beam weights and the like.

Specifically, the optimal beam is used for transmitting downlink information; the target switching beam is used for performing target beam switching; and the spare beam is used when the transmission direction of the optimal beam is blocked. The optimal beam is used for information interaction between the UE and the base station. The UE is carried by the user or carried by the device and is mobile. If the UE moves, the location relationship between the UE and the base station is changed. At this time, the optimal beam that the UE can detect also changes. In the embodiment, the n beams are determined in advance according to the moving direction of the UE, and the optimal beam that the UE may detect at the next moment is determined to facilitate the switching of the optimal beam.

The second feedback information may be used for beam selection of a next monitoring area, or selection and switching of a cell to which the UE is connected. In summary, this embodiment provides a downlink beam detecting method. The method can reduce power consumption consumed by the UE detecting a beam, reduce a detection load of the UE, and extend a standby duration of the UE.

It should be noted that the above n beams may be sent by one base station, or may be sent by different base stations, and are not limited to one base station.

The scanning area and the monitoring area herein may correspond to the aforementioned scanning area and monitoring area applied to the UE. The base station transmits m beams in the scanning zone, where the m beams can be all beams that the base station can transmit or can use for communication. The UE performs downlink beam quality detection on the m beams, and then feeds back to the base station in the form of first feedback information, and the base station selects at least a beam for transmitting downlink information to the UE according to the first feedback information. The downlink beam here may include various information that the base station needs to send to the UE, such as downlink control information and downlink service information.

In the embodiment, the second feedback information received by the base station from the UE is formed by detecting the n beams, and the second feedback information is assumed to be the downlink beam quality of the n beams, which is obviously relative to m The downlink beam quality of the beam can reduce the amount of data and simplify the information processing capacity of the base station.

The optimal beam is used for transmitting downlink information; the target switching beam is used for performing beam switching target beam; and the spare beam is used to replace the optimal when the optimal beam transmission direction is occluded A beam is used for information exchange between the UE and the base station.

Of course, the n beams may include only the optimal beam, or may only include the optimal beam and the target switching beam, or the optimal beam and/or the spare beam.

In some embodiments, the step S210 may include: transmitting the m beams with a fixed gain and/or a fixed weight and/or a fixed transmission direction;

The step S202 may include transmitting the n beams with a fixed gain and/or a fixed weight and/or a fixed transmission direction.

The m beam and the n beams are transmitted by using a fixed gain or a fixed weight. This ensures that the receiving effect of the UE on the same beam is consistent. In this way, the monitoring area can be determined according to the downlink beam quality of the m beams of the scanning area. n beams, according to n of the previous monitoring area The downlink beam quality of the beam determines the downlink beam quality of the n beams of the next monitoring area.

As shown in FIG. 4, more than one monitoring area may be disposed before two adjacent scanning areas. In this embodiment, in order to ensure that n beams transmitted to the UE are most suitable, to further ensure the communication quality of the UE, The beam of the current monitoring area is determined according to the previous monitoring area. A plurality of monitoring areas are disposed between two adjacent scanning areas, which can further reduce the probability of the base station transmitting all beams, and further reduce the power consumption of the base station and the antenna busyness. There are five monitoring areas disposed between the two scanning areas shown in FIG. 4. In a specific implementation, the number of the monitoring areas is not limited to five.

For example, in some cases, the downlink beam quality of the current n beams of the second feedback information is not good, and the base station may trigger the UE to perform cell reselection.

In the embodiment, the scanning area and the monitoring area may be statically set. For example, both the scanning area and the monitoring area may be periodic. Of course, the scanning area and the monitoring area can also be dynamically set. For example, when the UE finds that the downlink beam quality of the currently detected n beams is lower than the threshold, the beam search request is sent to the base station. After receiving the beam search request, the base station dynamically determines the scan area. Certainly, the base station may further determine, according to the second feedback information, that when the downlink beam quality of the n beams corresponding to the current UE is lower than the threshold, the scanning area is automatically reset, and the UE is notified by sending a command to perform m Full detection of the beam.

As shown in FIG. 9 , in this example, the base station downlinks 1 to 32 beam scans; the UE performs reception and feeds back measurement information; and the base station configures a monitoring area downlink transmission beam according to UE feedback. In the example shown in FIG. 8, beams 23, 24, 25, and 11 are selected; the UE receives in the monitoring area and feeds back measurement information; and the base station selects the optimal beam 24 for downlink control information or data information transmission.

Optionally, the base station performs traversal of 32 beams in the scanning area, and the UE performs feedback according to the downlink beam information acquired by the scanning area. The optimal beam 24 is fed back, as well as the adjacent sub-optimal beams 23 and 25. The movement of the beam 24 of 23 and 25 or so switches the target beam. The UE measures the downlink beam according to another reverse antenna, and acquires a beam 11 having a certain spatial isolation from the beam 24, and the signal 11 is a spare beam that is rotated or occluded by the UE.

The base station is used as an analog beam transmitted by the subsequent traffic channel and the control channel according to the optimal beam acquired after the beam scanning. Digital beamforming training and beam selection can be further performed on this beam basis.

The subsequent base station may perform the transmission of the monitoring area based on the period or the triggering manner, and the UE pairs Feedback is made on the beam quality in the monitored area. The UE may select a beam with enhanced received energy as a downlink analog beam according to the intensity variation of the beams 23, 24, and 25 in subsequent transmissions. In the monitoring area, the beam 26 can be sequentially selected as the switching target switching beam for monitoring according to the change of the beam intensity.

When the beams 23, 24, 25 are simultaneously greatly degraded, but the performance of the beam 11 can still be used, the subsequent base station can transmit the control information or the service information through the beam 11.

When the beam performance in the monitoring area is poor, the cell handover or beam re-search is triggered.

As shown in FIG. 8 , before the UE feeds back the measurement information, the UE selects the strongest receiving capability as the optimal beam; the adjacent sub-optimal beam serves as the target switching beam of the handover; and selects the receiving strongest beam that faces the UE antenna panel and satisfies The beam with the optimal spatial isolation of the optimal beam is the spare beam. The UE periodically feeds back the quality information of the beam in the monitoring area. The measurement information is one of the aforementioned feedback information.

Example four:

As shown in FIG. 10, the downlink beam processing method provided in this example includes:

Step 11: The multi-base station simultaneously performs beam scanning of the downlink cell; for example, base station 1 (BTS_1) and base station 2 (BTS_2) in FIG.

Step 12: The UE performs downlink beam detection, and performs selection of an optimal beam, a target switching beam, and an alternate beam.

Step 13: Simultaneously transmit feedback information of the base station 1 and the base station 2 according to the downlink detection.

Step 14: The base station may perform downlink transmission of the monitoring area at the same time or at different times according to the configuration.

Step 15: When the beam quality of the UE transmitting base station 1 is poor, the detection information needs to be reported.

Step 16: Both the base station 1 and the base station 2 receive the report of the UE, and learn the service status of the base station 1. Poor state.

Step 17: Perform information exchange between the base station 1 and the base station 2. For example, the information interaction may include cell selection, handover, or interaction of connection state transition information, so that the UE disconnects from the base station 1 and resides only at the base station. 2 formed within the cell.

Step 18: The base station 2 performs transmission of the downlink monitoring area and corresponding service services.

Beam detection in multiple surveillance zones is divided into two broad categories:

The first type: the UE detects only the beam transmitted by one cell in the monitoring area at one time point. This type of situation is divided into two sub-cases. For example, as shown in FIG. 11 and FIG. 13, the UE can detect the beams transmitted by the two cells in the monitoring area at one time. At this time, the two cells are required to be processed by negotiation or the like, and the settings of the monitoring areas of the two cells are consecutive and do not overlap in the time dimension. As shown in FIG. 12, the UE detects only the beam transmitted by one cell in the monitoring area at a time. Usually, the time corresponding to the monitoring areas of the two cells does not overlap or is continuous.

The second type: the UE transmits the beams of the two cells in the monitoring area at the same time. For example, the monitoring areas of the two cells are the same. At this time, if the UE is in the overlapping coverage area of the two cells, the beams of the two cells can be detected at the same time. Usually, at this time, the beams of the two cells in the monitoring area at the same time are required to have orthogonality.

In summary, the UE performs beam scanning on the base station 1 and the base station 2, and combines the target switching beams of the two base stations to perform information reporting. The reporting information includes downlink target switching beams of two base stations. The base stations 1, 2 can configure the transmission of the monitoring area according to different periods and times.

When the downlink beam performance of the monitoring area of the base station 1 is degraded, the UE reports the information of the degradation of the beam quality, and the base station 2 serves the UE.

In addition, the base station 1 can select a base station beam or a beam of the base station 2 as a target switching beam that the UE performs measurement in the monitoring area according to the target switching beam (including the target switching beam of the base station 1 and the base station 2) reported by the UE. When the quality of the beam service of the cell decreases, the base station 1 can configure the UE to receive downlink control information and/or downlink service information from the downlink beam of the base station 2. interest.

The base station 2 can configure the downlink monitoring area to cooperate with the base station 1 according to the service condition, so that the UE can measure the monitoring areas of the two cells at a time. It can also be configured as 2 transmission opportunities for the UE to measure. When BTS1 and BTS2 do not distinguish between cell IDs, or two cell beams do not have orthogonality, the beams transmitted by the two cells in the monitoring area may be simultaneously detected.

Example five:

As shown in FIG. 14 , the base station configures, according to the result of the scanning and reporting of the UE, the beam that is sent in the monitoring area corresponding to the UE1 as the beam 21, 24, 25, and 26, and the beam that is transmitted in the monitoring area corresponding to the UE2 is the beam 12. 15,16,17. The UE1 monitors the beams 21, 24, 25, 26, wherein the optimal beam is the beam 25, the target switching beam is the beam 24, 26, and the standby beam is the beam 21.

When beam 25 receives energy, it is lower than the last time, but beam 26 energy is increased. After a plurality of monitoring area measurements, when the beam 26 is found to be better than the beam 25 to a certain extent, or is optimal, the UE reports the result to the base station. The base station can adjust the range of the monitoring area and the beam used by the corresponding service and control channel according to the reported information.

When the beams 24, 25, 26 are all lowered, but the performance of the beam 21 is still stable, it can be judged that the main transmission direction is blocked. After the measurement is reported, the base station can switch the service or control channel to the beam 21 for downlink communication.

When the performance of the beams 24, 25, 26, 21 is degraded and a certain threshold is reached, the base station may consider triggering the beam re-scanning of the UE and/or the handover procedure of the cell.

Example six:

As shown in FIG. 15 , the base station configures, according to the result of the scanning and reporting of the UE, the beam that is sent in the monitoring area corresponding to the UE1 as the beam 21, 24, and 25, and the beam transmitted in the monitoring area corresponding to the UE2 is the beam 12, 15, 16 , 17. The UE1 monitors the beams 21, 24, 25, and 26, wherein the optimal beam is the beam 25, and the target switching beam is the beam 24, 26, and the standby The beam is beam 21. In addition, the base station can configure another monitoring area for the UE to perform beam monitoring. At the same time, the multiple UEs can share the monitoring area configured by the base station. In FIG. 16, UE1 and UE2 share the monitoring area 1 configured by the base station; UE2 and UE3 share the monitoring area 2 configured by the base station.
