Description

Beam management method and device
Technical Field
The present invention relates to the field of communications, and in particular, to a method and an apparatus for beam management.
Background
The beam forming is a signal preprocessing technology based on an antenna array, and generates a directional beam by adjusting the weighting coefficient of each array element in the antenna array, so that obvious array gain can be obtained. In New Radio (NR), in order to combat path loss in high frequency scenarios, the antenna array introduces more beamforming to gain. Since the data channel, the control channel, the synchronization signal, and the broadcast signal can be transmitted through the Beam, Beam Management (BM) is important in NR.
In 3rd Generation Partnership Project (3 GPP) related meetings, downstream beam management in NR can be divided into three phases: p-1, P-2 and P-3. In the stage P-1, a User Equipment (UE) may select one or more transmit beams through measurement, and establish a transceiving beam association with one or more receive beams. The transmit beams in the established transceiving beam association may be from one or more Transmission Receiver Points (TRPs), and the receive beams may be from the UE. And normal communication service can be carried out between the TRP and the UE through the established receiving and transmitting beam association. In the P-2 phase, the UE may update the transmit beam of the one or more transceiver beam associations according to the measurement results. The transmit beam may still be from one or more TRPs but is generally smaller than the candidate range for the P-1 phase. In the P-3 phase, the UE may update the receive beams in one or more of the transceive beam associations according to the measurement results. The receive beams may still come from the UE. It will be appreciated that the P-2 phases and P-3 phases are a subset of the P-1 phases.
In an actual communication process, the UE may move, rotate or be blocked (blocked), and the above behaviors may cause a rapid decrease or even an interruption of communication quality in a system based on beam access, and once a current transceiving beam association cannot meet a transmission requirement or is directly interrupted, a series of operations such as reconnection, re-beam scanning and the like need to be performed between the base station and the UE, which brings an overhead of resource delay. Therefore, in view of system robustness, multiple transmit-receive beam associations should be established and maintained to reduce the probability of reconnection due to communication interruption.
The introduction of a common identity is considered to be an efficient and compact way of managing the association of multiple transceiving beams, i.e. the base station establishes and maintains an association between its transmitting beam and the common identity associated with the transceiving beam, and the UE establishes and maintains an association between its receiving beam and the common identity associated with the transceiving beam. Based on the method, the base station may require the UE to monitor the communication quality of multiple transceiving beam associations and enable the transceiving beam association with better communication quality to increase the robustness of communication when the communication quality of the current transceiving beam association decreases.
However, in the method discussed in the prior art, the system cannot guarantee that the public identifier associated with the transmit-receive beam issued by the base station can be successfully received by the UE, so that the base station and the UE have completely inconsistent subsequent processing on the public identifier issued by the base station at a certain time, and such an incorrect public identifier has a serious influence on the communication robustness in the system based on beam access.
Disclosure of Invention
The technical problem to be solved by the embodiments of the present invention is to provide a beam management method and a device thereof, which can implement handshake between a base station and user equipment for a public identifier associated with a received and transmitted beam, and further can improve communication robustness based on a beam access system.
In a first aspect, an embodiment of the present invention provides a beam management method, including: the method comprises the steps that network equipment sends first information carrying at least one public identification to user equipment, wherein the at least one public identification indicates association between a sending beam of the network equipment and a receiving beam of the user equipment; and the network equipment receives second information which is sent by the user equipment and carries a receiving success identification or a default identification, wherein the receiving success identification indicates that the user equipment monitors the at least one public identification, and the default identification indicates that the user equipment does not monitor the at least one public identification. After the network device sends the first information carrying at least one public identity, whether the user device receives the at least one public identity is determined through a successful receiving identity or a default identity carried by the received second information, so that handshake between the network device and the user device for the at least one public identity can be realized, and further communication robustness based on the beam access system can be improved.
In a possible implementation manner, after receiving second information carrying a default identifier sent by the user equipment, the network device sends the first information carrying the at least one public identifier to the user equipment again, and receives the second information carrying the reception success identifier or the default identifier sent by the user equipment again, that is, repeatedly sends the second information until the user equipment receives the at least one public identifier, and the user equipment receives the second information carrying the reception success identifier sent by the user equipment, so as to implement handshake between the network device and the user equipment for the at least one public identifier.
In a possible implementation manner, the at least one common identifier is used to trigger beam scanning, that is, the network device performs beam scanning when or after transmitting the first information carrying the at least one common identifier, and the user equipment performs beam scanning when receiving the at least one common identifier.
In a possible implementation manner, after receiving second information carrying a reception success identifier sent by the user equipment, the network equipment sends a beam scanning trigger instruction to the user equipment, where the beam scanning trigger instruction is used to trigger beam scanning. Namely, after receiving the second information carrying the receiving success identifier sent by the user equipment, the network equipment executes beam scanning, sends a beam scanning trigger instruction, and triggers the user equipment to execute beam scanning.
In a possible implementation manner, before the network device receives second information carrying a reception success identifier or a default identifier sent by the user equipment, the network device sends a beam scanning trigger instruction to the user equipment, where the beam scanning trigger instruction is used to trigger beam scanning.

The user equipment realizes handshake between the network equipment and the user equipment for at least one public identification by feeding back second information carrying the successful receiving identification or the default identification to the network equipment, so that the communication robustness of the beam-based access system can be improved.
In a possible implementation manner, after sending, by the user equipment, second information carrying a default identifier to the network equipment according to a monitoring result, monitoring, by the user equipment, the first information carrying the at least one public identifier sent by the network equipment again; and sending the second information carrying the successful receiving identifier or the default identifier to the network equipment according to the monitoring result again.
In a possible implementation manner, the at least one common identifier is used for triggering beam scanning, and the user equipment performs beam scanning according to the at least one common identifier.
In a possible implementation manner, after the user equipment sends second information carrying a successful receiving identifier to the network equipment according to a monitoring result, receiving a beam scanning trigger instruction sent by the network equipment; and executing beam scanning according to the beam scanning trigger instruction. I.e. the network device and the user equipment perform beam scanning after completing the handshake for the at least one common identity.
In a possible implementation manner, before the user equipment sends second information carrying a reception success identifier or a default identifier to the network equipment according to a monitoring result, receiving a beam scanning trigger instruction sent by the network equipment; and executing beam scanning according to the beam scanning trigger instruction. I.e. the user equipment performs a beam sweep before transmitting the second information.

Detailed Description
The embodiments of the present invention will be described below with reference to the drawings.
The embodiments of the present invention may be applied to a wireless communication system, which generally includes cells, each of which includes a Base Station (BS) that provides communication services to a plurality of user equipments, where the Base Station is connected to a core network device, as shown in fig. 1. The base station includes a Baseband Unit (BBU) and a Remote Radio Unit (RRU). BBU and RRU can be placed in different places, for example: RRU is remote and is placed in an open area with high telephone traffic, and BBU is placed in a central machine room. The BBU and the RRU can also be placed in the same machine room. The BBU and RRU can also be different components under one chassis.
It should be noted that, the wireless communication system according to the embodiment of the present invention includes, but is not limited to: narrowband Band-Internet of Things (NB-IoT), Global System for Mobile Communications (GSM), Enhanced Data rates for GSM Evolution (EDGE), Wideband Code Division Multiple Access (WCDMA), Code Division Multiple Access (Code Division Multiple Access, CDMA2000), Time Division-synchronous Code Division Multiple Access (TD-SCDMA), Long Term Evolution (Long Term Evolution, LTE), NR, and future Mobile communication systems.
In an embodiment of the present invention, the base station is a device deployed in a radio access network to provide a wireless communication function for a user equipment. The base stations may include various forms of macro base stations, micro base stations (also referred to as small stations), relay stations, access points, TRPs, etc. In systems using different radio access technologies, names of devices having a base station function may be different, for example, in an LTE system, the device is called an evolved Node B (eNB or eNodeB), and in a third Generation (3rd Generation, 3G) system, the device is called a Node B (NB). For convenience of description, in all embodiments of the present invention, the above-mentioned apparatus for providing a wireless communication function for a user equipment is collectively referred to as a network device.
User devices involved in embodiments of the present invention may include various handheld devices, vehicle mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem with wireless communication capabilities. The user equipment may also be referred to as a Mobile Station (MS), a Terminal (Terminal), and may further include a subscriber unit (subscriber unit), a cellular phone (cellular phone), a smart phone (smart phone), a wireless data card, a Personal Digital Assistant (PDA) computer, a tablet computer, a wireless modem (modem), a handheld device (handset), a laptop computer (laptop computer), a Machine Type Communication (MTC) Terminal, and the like. For convenience of description, in all embodiments of the present invention, the above-mentioned devices are collectively referred to as user equipment.
The common identifier involved in the embodiments of the present invention indicates an association between a transmission beam of a base station and a reception beam of a UE, that is, indicates a transceiving beam association, and may be specifically referred to as a transceiving beam associated common identifier. The common identifier is used for associating the transmission beam of the base station with the reception beam of the UE, and specifically, one common identifier may associate at least one transmission beam on the base station side and at least one reception beam on the UE side. It will be appreciated that the common identity is an intermediary between the transmit beam of the base station and the receive beam of the UE. For example, from the perspective of the base station, only the consistency of the transmission beam thereof with the common identifier needs to be maintained without knowing the specific UE-side reception beam information, and from the perspective of the UE, only the consistency of the reception beam thereof with the common identifier needs to be maintained without knowing the specific base station-side transmission beam information. More specifically, if there are A, B, C, D four transmission beams on the base station side, there are two reception beams a, b on the UE side. Assume that of a total of 8 possible transmit-receive beam scanning combinations, there are 2 satisfactory transmit-receive beam associations as follows: a-a, C-b, and the corresponding 2 public identities "T1", "T2". At this time, the base station only maintains the relation between the transmission beam A and the public identity T1 and the relation between the transmission beam C and the public identity T2; while the UE maintains only its receive beam a in relation to the common identity "T1" and receive beam b in relation to the common identity "T2". By such a mechanism, the common identifiers "T1" and "T2" become the intermediaries of the two pairs of transmit-receive beam associations, respectively.
The common identifier associated with the transmit-receive beam may be an antenna port number, such as a spatial Quasi-Co-Location port (spatial QCL port), or a Reference Signal resource number, such as a Channel State Information-Reference Signal (CSI-RS) port number or a CSI-RS resource number (CSI-RS resource index). In the embodiment of the present invention, for simplicity, the transmit-receive beam association may be replaced by a Beam Pair Link (BPL) with a closer technical essence, and the common identifier of the transmit-receive beam association may be described as a BPL common identifier. The definition, name of the public identity associated with the transmit and receive beams may vary in present or future standards, but names consistent with the technical essence of the concepts described herein are within the scope of the embodiments of the present invention.
At present, a system cannot guarantee that a BPL public mark issued by a base station can be successfully received by UE, so that problems may exist. Suppose that the UE does not receive the BPL public identity 1 issued by the base station, but receives the beam scanning trigger instruction issued by the base station, at this time, the base station performs beam scanning as usual, and the UE also performs beam scanning as usual, and feeds back the scanning result, but the base station and the UE have a deviation in "understanding" of the scanning result. For example, the base station associates the transmission beam a fed back by the UE with the BPL public identity 1 issued by the UE, while the UE does not associate the reception beam a with the BPL public identity 1 and may not know the public identity at all. When the base station then asks the UE to monitor this new BPL (transmit beam a-receive beam a), the UE does not know which receive beam to receive with, and the BPL cannot be used. Even when the base station switches to the transmit beam of this new BPL, the UE cannot match and communication is directly interrupted.
Similar situations where the base station and the UE have different "understandings" of the same BPL public identity may occur during the establishment and maintenance of the BPL public identity. In view of this, embodiments of the present invention provide a beam management method, which can implement handshake between a base station and a UE for BPL public identities, ensure correct establishment and maintenance of multiple BPLs, and further improve communication robustness based on a beam access system.
The beam management method provided by the embodiment of the invention will be described in detail with reference to fig. 2 to 6.
Referring to fig. 2, fig. 2 is a communication schematic diagram of a beam management method according to an embodiment of the present invention, introduced from the perspective of interaction between a network device and a user equipment, where the method includes, but is not limited to, the following steps:
step S201: the network equipment sends first information carrying at least one public identification to the user equipment;
the ue may be any ue within the coverage of the network device, or may be any ue outside the coverage of the network device. If the user equipment is within the coverage of the network equipment, the user equipment may or may not receive the at least one public identity. And if the user equipment is out of the coverage range of the network equipment, the user equipment cannot receive the at least one public identity.
Specifically, the network device sends the first information carrying the at least one public identifier to the user device, where the at least one public identifier indicates an association between a transmission beam of the network device and a reception beam of the user device, that is, indicates a beam pairing relationship. One common identity may be associated with at least one transmit beam of the network device, at least one receive beam of the user equipment. The first Information may be Downlink Control Information (DCI), where the at least one common identifier may be indicated by an identifier indicator in the DCI, a bit number of the identifier indicator may be related to a number of beam pairing relationships, and a specific value is determined according to a specific situation, which is not limited in this embodiment of the present invention, for example, the identifier indicator uses 2 bits to indicate the common identifier of the beam pairing relationship.
In a possible implementation manner, the DCI also carries a beam scanning trigger instruction, and the beam scanning trigger instruction may occupy 1 bit, for example, when the bit is "1", it indicates to carry the beam scanning trigger instruction, and when the bit is "0", it indicates not to carry the beam scanning trigger instruction. And when the network equipment sends the DCI carrying the at least one public identity and the beam scanning trigger instruction, the network equipment can execute beam scanning, namely, a base station side executes beam scanning. And when the user equipment receives the DCI carrying the at least one public identity and the beam scanning trigger instruction, the user equipment can execute beam scanning, namely the UE side executes the beam scanning according to the beam scanning trigger instruction.
Optionally, the at least one common identifier is independent from the beam scanning trigger instruction, but both are carried in the same DCI. Optionally, the at least one common identifier and the beam scanning triggering instruction are combined into the same instruction, and the instruction may indicate the at least one common identifier and trigger beam scanning.
In a possible implementation manner, the DCI does not carry a beam scanning trigger instruction, but the at least one common identifier may trigger beam scanning, that is, the network device may perform beam scanning when transmitting the DCI carrying the at least one common identifier, that is, a base station side performs beam scanning. And when the user equipment receives the DCI carrying the at least one public identity, the user equipment can execute beam scanning, namely the UE side executes the beam scanning according to the at least one public identity. In other words, in this possible implementation manner, the at least one public identity is used for triggering beam scanning in addition to the indication identity, which is equivalent to a function of fusing the beam scanning triggering instruction in the at least one public identity, and DCI overhead can be saved.
In the foregoing two possible implementation manners, the beam scanning performed by the network device and the beam scanning performed by the user equipment may be non-periodic beam scanning. The aperiodic beam scan may correspond to the P-2 or P-3 phase of NR downlink beam management. The aperiodic (nonperiodic) may be semi-persistent (semi-persistent) or aperiodic (aperiodic).
The network device may send the DCI to the user equipment through a Physical Downlink Control Channel (PDCCH). The DCI transmission procedure in the PDCCH may include Cyclic Redundancy Check (CRC), scrambling, channel coding, rate matching, interleaving, and other processes.
Step S202: the user equipment monitors the first information which is sent by the network equipment and carries the at least one public identification;
specifically, because the factors affecting the radio channel transmission are many and complicated, the first information sent by the network device may or may not be received by the user equipment, and therefore the user equipment needs to monitor the first information carrying the at least one public identifier sent by the network device.
In a possible implementation manner, when the user equipment receives the first information, an error occurs in decoding or CRC processing on the first information, the first information cannot be obtained, and the at least one public identity is naturally not obtained, and it may be determined that the user equipment does not monitor the at least one public identity.
In a possible implementation manner, the user equipment obtains the first information but does not obtain the at least one public identity, and it may be determined that the user equipment does not listen to the at least one public identity.
In a possible implementation manner, the user equipment does not listen to the first information, and thus does not listen to the at least one public identity.
The user equipment can determine that the user equipment hears the at least one public identity under the condition that the first information is received and the first information and the at least one public identity can be obtained.
And if the at least one public identity can trigger beam scanning, the user equipment executes beam scanning under the condition of monitoring the at least one public identity. After beam scanning is completed, scanning results may be obtained, and the user equipment may associate a reception beam in the scanning results with the at least one public identity.
Step S203: the user equipment sends second information carrying a receiving success identification or a default identification to the network equipment according to a monitoring result;
specifically, the ue sends, to the network device, second information carrying a successful reception identifier when monitoring the at least one public identifier, where the successful reception identifier indicates that the ue monitors the at least one public identifier. And the user equipment sends second information carrying a default identifier to the network equipment under the condition that the user equipment does not monitor the at least one public identifier, wherein the default identifier indicates that the user equipment does not monitor the at least one public identifier. The situation that the user equipment does not listen to the at least one public identity may be determined according to three possible implementations listed in step S202.
The second Information may be Uplink Control Information (UCI). An indication bit of 1 bit may be added to the UCI to indicate the reception success flag or the default flag, for example, if the indication bit is "1", the indication bit indicates the reception success flag, and if the indication bit is "0", the indication bit indicates the default flag. The 1 bit occupied by the indicator bit can be an independent 1 bit, and can also be combined with other reported information.
It should be noted that the user equipment sends the second information carrying the successful receiving identifier to the network equipment only when monitoring the at least one public identifier, and the user equipment sends the second information carrying the default identifier to the network equipment by default in other cases.
If the at least one public identity can trigger beam scanning, the user equipment executes beam scanning under the condition of monitoring the at least one public identity, so that a scanning result can be obtained, and a receiving beam in the scanning result is associated with the at least one public identity. And the user equipment sends the scanning result to the network equipment. Since the ue monitors the at least one public identity and the at least one public identity may trigger beam scanning, the ue may send the second information carrying the successful receiving identity and the scanning result to the network device, and both may send them at the same time or in a sequential order. When the information is sent simultaneously, the information can be sent independently and simultaneously, and also can be sent through the same information.
Step S204: the network equipment receives the second information which is sent by the user equipment and carries the successful receiving identification or the default identification;
specifically, the network device receives the second information carrying the successful receiving identifier or the default identifier sent by the user equipment. If the second information received by the network device carries the successful receiving identifier, the network device may determine that the user equipment receives the at least one public identifier without sending the first information carrying the at least one public identifier again. If the second information received by the network device carries the default identifier, the network device may determine that the user equipment does not receive the at least one public identifier, and needs to send the first information carrying the at least one public identifier again, and receive the second information carrying the reception success identifier or the default identifier sent by the user equipment again, that is, for the network device, step S201 and step S204 are repeated, and for the user equipment, step S202 and step S203 are repeated.
In a case that the network device determines that the user equipment receives the at least one public identity and the at least one public identity can trigger beam scanning, the network device may further receive the scanning result sent by the user equipment and associate a sending beam in the scanning result with the at least one public identity.
In the embodiment shown in fig. 2, after the network device sends the first information carrying at least one public identity, the user device realizes handshake between the network device and the user device for the at least one public identity by feeding back the second information carrying a successful reception identity or a default identity, so that the problems of invalidity of the at least one public identity and beam management caused thereby can be avoided, and further, the communication robustness based on the beam access system can be improved.

specifically, the user equipment sends second information carrying a successful receiving identifier to the network equipment under the condition that the beam pairing relationship public identifier is monitored.
Step S304: the network equipment receives the second information which is sent by the user equipment and carries the receiving success identification;
specifically, when receiving the second information carrying the successful reception identifier sent by the user equipment, the network device may determine that the user equipment receives the beam pairing relationship public identifier.
Step S305: the network equipment sends a beam scanning trigger instruction to the user equipment;
specifically, after receiving the second information carrying the successful receiving identifier, the network device sends a beam scanning trigger instruction to the user equipment. Simultaneously with or after the beam scanning trigger instruction is sent, the network device performs beam scanning, which may specifically be performing aperiodic beam scanning.
Step S306: the user equipment receives the beam scanning trigger instruction sent by the network equipment;
step S307: the user equipment executes beam scanning according to the beam scanning trigger instruction;
specifically, when receiving the beam scanning trigger instruction, the user equipment performs beam scanning according to the beam scanning trigger instruction, which may specifically be to perform aperiodic beam scanning. After the beam scanning is completed, a scanning result may be obtained, and the user equipment may associate a reception beam in the scanning result with the beam pairing relationship common identifier, and send the scanning result to the network device. The scanning result sent by the user equipment to the network equipment may include an association between a receiving beam and the beam pairing relationship common identifier.
And when receiving the scanning result, the network device associates the transmitting beam in the scanning result with the beam pairing relationship public identifier, so as to establish association among the transmitting beam, the beam pairing relationship public identifier and the receiving beam.
In the embodiment shown in fig. 3, the network device triggers beam scanning only when determining that the user equipment monitors the beam pairing relationship common identifier, and the network device or the user equipment does not blindly perform beam scanning, so that a situation that the network device and the user equipment "understand" the beam pairing relationship common identifier is inconsistent can be avoided, and further, a problem that the beam pairing relationship common identifier is invalid and beam management caused by the invalid beam pairing relationship common identifier can be avoided, and further, communication robustness based on the beam access system can be improved.

Step S408: the network equipment receives the scanning result sent by the user equipment and temporarily stores the scanning result;
it should be noted that steps S403 to S408 are performed before step S409, that is, during the process that the network device waits to receive the second information carrying the reception success identifier or the default identifier, in which process, the network device may complete beam scanning, and the user equipment may also complete beam scanning. Step S401 may be executed before step S403, or may be executed simultaneously with step S403.
Step S409: the user equipment sends the second information carrying the default identification to the network equipment according to the monitoring result;
specifically, the user equipment sends the second information carrying the default identifier to the user equipment without monitoring the public identifier of the beam pairing relationship.
The user equipment may send the scanning result and the second information carrying the default identifier to the network equipment at the same time when receiving the uplink resource and not monitoring the beam pairing relationship public identifier, that is, step S407 and step S409 may be executed at the same time.
The user equipment may send the scanning result and the second information carrying the successful receiving identifier to the network equipment at the same time when receiving the uplink resource and monitoring the beam pairing relationship public identifier, and associate the receiving beam in the scanning result temporarily stored in step S405 with the beam pairing relationship public identifier. And when the network equipment receives the scanning result and the second information carrying the successful receiving identification, associating the transmitting beam in the scanning result with the beam pairing relation public identification.

step S410 and step S408 may be performed simultaneously.
Step S411: the network equipment sends the first information carrying the public identification of the beam pairing relationship to the user equipment again;

specifically, the beam pairing relationship common identifier and the beam scanning trigger instruction may be relatively independent, but are all carried in the same first information. The beam pairing relationship public identification and the beam scanning trigger instruction can be combined into the same instruction and carried in first information. The network device simultaneously sends the beam pairing relationship public identifier and the beam scanning trigger instruction, so that the probability that the user equipment only receives the beam scanning trigger instruction can be reduced.
Step S502: the user equipment monitors the first information which is sent by the network equipment and carries the beam pairing relation public identification and the beam scanning triggering instruction;
step S503 a: the user equipment sends second information carrying a receiving success identification and a scanning result to the network equipment according to the monitoring result;
specifically, the user equipment sends second information carrying a successful receiving identifier to the network equipment under the condition that the beam pairing relationship public identifier is monitored. And under the condition that the beam pairing relation public identity is monitored, deducing that the beam scanning trigger instruction is monitored, executing beam scanning by the user equipment to obtain a scanning result, and associating the receiving beam in the scanning result with the beam pairing relation public identity.

Step S504 b: the network equipment receives the second information carrying the successful receiving identification and the scanning result sent by the user equipment;

Step S503 a: the user equipment sends second information carrying a default identification to the network equipment according to a monitoring result;
specifically, the user equipment may conclude that the beam scanning trigger instruction is not monitored when the user equipment does not monitor the beam pairing relationship public identifier, and then the user equipment does not perform beam scanning and only sends the second information carrying the default identifier to the user equipment.
Step S504 b: the network equipment receives the second information which is sent by the user equipment and carries the default identification;
specifically, the network device needs to send the first information carrying the beam pairing relationship common identifier and the beam scanning trigger instruction to the user device again when receiving the second information carrying the default identifier sent by the user device.

In the embodiment shown in fig. 5, the network device simultaneously issues the beam pairing relationship common identifier and the beam scanning trigger instruction, and associates the transmission beam in the scanning result with the beam pairing relationship common identifier when receiving the reception success identifier fed back by the user equipment.

step S603: the user equipment sends a scanning result to the network equipment according to the monitoring result;
specifically, the user equipment may infer that the beam scanning trigger instruction is monitored when monitoring the beam pairing relationship common identifier, and then execute beam scanning by the user equipment to obtain a scanning result, associate a receiving beam in the scanning result with the beam pairing relationship common identifier, and send the scanning result to the network equipment.
The difference from the embodiment shown in fig. 5 is that fig. 5 transmits the second information carrying the reception success flag and the scanning result in this case, and fig. 6 transmits only the scanning result in this case.
