一种波束管理方法及其装置Beam management method and device thereof

技术领域Technical field
本发明涉及通信领域,尤其涉及一种波束管理方法及其装置。The present invention relates to the field of communications, and in particular, to a beam management method and apparatus therefor.
背景技术Background technique
波束赋形是一种基于天线阵列的信号预处理技术,波束赋形通过调整天线阵列中每个阵元的加权系数产生具有指向性的波束,从而能够获得明显的阵列增益。在新无线(New Radio,NR)中,为了在高频场景下对抗路径损耗,天线阵列更多地会引入波束赋形来获得增益。数据信道、控制信道、同步信号、广播信号都可以通过波束进行发送,因此,波束管理(BeamManagement,BM)在NR中显得较为重要。Beamforming is a signal preprocessing technique based on an antenna array. Beamforming produces a directional beam by adjusting the weighting coefficients of each element in the antenna array, so that a significant array gain can be obtained. In New Radio (NR), in order to combat path loss in high frequency scenes, the antenna array introduces beamforming more to obtain gain. The data channel, control channel, synchronization signal, and broadcast signal can all be transmitted through the beam. Therefore, Beam Management (BM) is more important in NR.
在第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)相关会议中,NR中下行波束管理可以分为三个阶段:P-1,P-2和P-3。其中,在P-1阶段,用户设备(User Equipment,UE)可以通过测量选择一个或多个发送波束,与一个或多个接收波束建立收发波束关联。所建立的收发波束关联中的发送波束可以来自于一个或多个传输接入点(TransmissionReceiverpoint,TRP),接收波束可以来自于UE。通过建立的收发波束关联,TRP与UE之间可以进行正常的通信业务。在P-2阶段,UE可以根据测量结果对一个或多个收发波束关联中的发送波束进行更新。发送波束仍然可以来自于一个或多个TRP,但一般比P-1阶段的候选范围小。在P-3阶段,UE可以根据测量结果对一个或多个收发波束关联中的接收波束进行更新。接收波束仍然可以来自于UE。可以理解的是,P-2阶段和P-3阶段是P-1阶段的子集。In the 3rd Generation Partnership Project (3GPP) related conference, NR mid-downlink beam management can be divided into three phases: P-1, P-2 and P-3. In the P-1 phase, the user equipment (User Equipment, UE) can select one or more transmit beams by measurement, and establish a transceiving beam association with one or more receive beams. The transmit beam in the established transmit and receive beam association may be from one or more Transmission Access Points (TRPs), and the receive beam may be from the UE. Through the established transceiver beam association, normal communication services can be performed between the TRP and the UE. In the P-2 phase, the UE may update the transmit beam in one or more transmit and receive beam associations according to the measurement result. The transmit beam can still come from one or more TRPs, but is generally smaller than the candidate range of the P-1 phase. In the P-3 phase, the UE may update the receive beams in one or more transmit and receive beam associations according to the measurement results. The receive beam can still come from the UE. It will be appreciated that the P-2 phase and the P-3 phase are a subset of the P-1 phase.
实际通信过程中,UE可能移动、旋转或被阻断(blockage)等,上述行为在基于波束接入的系统中,可能会造成通信质量迅速下降或甚至中断,一旦当前的收发波束关联不能满足传输要求或直接中断的情况下,基站和UE之间又需要进行重连、重新波束扫描等一系列操作,带来资源的时延的开销。因此从系统鲁棒性考虑,应该建立和维护多个收发波束关联,以降低通信中断重连的概率。During the actual communication process, the UE may move, rotate, or blockage. The above behavior may cause the communication quality to rapidly drop or even be interrupted in the beam access-based system. Once the current transceiver beam association cannot satisfy the transmission. In the case of a request or a direct interruption, a series of operations such as reconnection and re-beam scanning are required between the base station and the UE, which brings the delay of resource delay. Therefore, from the perspective of system robustness, multiple transceiver beam associations should be established and maintained to reduce the probability of communication interruption reconnection.
引入公共标识被认为是管理多个收发波束关联的一种高效简洁的方法,即基站建立和维护其发送波束与收发波束关联的公共标识之间的关联,UE建立和维护其接收波束与收发波束关联的公共标识之间的关联。基于该方法,基站可以要求UE监控多个收发波束关联的通信质量,并在当前的收发波束关联的通信质量下降时启用通信质量更好的收发波束关联来增加通信的鲁棒性。The introduction of a public identity is considered to be an efficient and concise method of managing multiple transmit and receive beam associations, that is, the base station establishes and maintains an association between its transmit beam and a public identity associated with the transmit and receive beams, and the UE establishes and maintains its receive beam and transmit and receive beams. The association between the associated public identities. Based on the method, the base station may require the UE to monitor the communication quality associated with the plurality of transceiver beams, and enable the better communication and reception beam association to improve the robustness of the communication when the communication quality associated with the current transceiver beam decreases.
但是现有讨论的方法中,系统无法保障基站下发的收发波束关联的公共标识一定能被UE成功接收,由此造成基站和UE对基站某一次下发的公共标识有完全不一致的后续处理,而这样一个错误的公共标识在基于波束接入的系统中,对通信鲁棒性的影响十分严重。However, in the existing method, the system cannot ensure that the public identifier associated with the transmitting and receiving beams sent by the base station can be successfully received by the UE, and the base station and the UE have completely inconsistent subsequent processing on the public identifier sent by the base station. Such a wrong public identity has a significant impact on communication robustness in beam-based systems.

For convenience of description, in all embodiments of the present invention, the above-mentioned devices are collectively referred to as user devices.
本发明实施例中所涉及到的公共标识指示基站的发送波束与UE的接收波束之间的关联,即指示收发波束关联,具体可以称为收发波束关联的公共标识。该公共标识用于关联基站的发送波束和UE的接收波束,具体地,一个公共标识可以关联基站侧的至少一个发送波束,UE侧的至少一个接收波束。可以理解的是,该公共标识是基站的发送波束与UE的接收波束之间的中介。例如,从基站的角度,只需要维护其发送波束与该公共标识的一致性,而不需要获知具体的UE侧接收波束信息,而从UE的角度,只需要维护其接收波束与该公共标识的一致性,而不需要获知具体的基站侧发送波束信息。更为具体地,假如基站侧存在A、B、C、D四个发送波束,UE侧存在a、b两个接收波束。假设在一共8种可能的收发波束扫描组合中,有如下2个符合要求的收发波束关联:A-a、C-b,和对应的2个公共标识“T1”、“T2”。此时基站只维护其发送波束A与公共标识“T1”,以及发送波束C 与公共标识“T2”的关系;而UE只维护其接收波束a与公共标识“T1”,以及接收波束b与公共标识“T2”的关系。通过这样的机制,公共标识“T1”和“T2”分别成为了上述两对收发波束关联的中介。The common identifier in the embodiment of the present invention indicates the association between the transmit beam of the base station and the receive beam of the UE, that is, the association of the transmit and receive beams, which may be referred to as a public identifier associated with the transmit and receive beams. The public identifier is used to associate the transmit beam of the base station with the receive beam of the UE. Specifically, a common identifier may be associated with at least one transmit beam on the base station side and at least one receive beam on the UE side. It can be understood that the public 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 transmit beam and the public identifier needs to be maintained, and the specific UE side receive beam information needs to be learned. From the perspective of the UE, only the receive beam and the public identifier need to be maintained. Consistency, without the need to know the specific base station side transmit beam information. More specifically, if there are four transmit beams A, B, C, and D on the base station side, there are two receive beams a and b on the UE side. Assuming a total of 8 possible transmit and receive beam scan combinations, there are 2 eligible transmit and receive beam associations: A-a, C-b, and corresponding 2 public identifiers "T1", "T2". At this time, the base station only maintains its transmit beam A and the public identifier "T1", and the relationship between the transmit beam C and the public identifier "T2"; and the UE only maintains its receive beam a and the public identifier "T1", and the receive beam b and the public Identifies the relationship of "T2". Through such a mechanism, the public identifiers "T1" and "T2" become the mediation of the above two pairs of transceiver beam associations, respectively.
上述收发波束关联的公共标识的载体可以是一个天线端口号,如空间准协同定位端口(spatial Quasi-Co-Location port,spatial QCLport),也可以是参考信号资源序号,如信道状态信息参考信号(Channel State Information-Reference Signal,CSI-RS)端口号或CSI-RS资源序号(CSI-RS resource index)。在本发明实施例中,为简明起见,可以技术本质更为接近的概念波束配对关系(beampair link,BPL)替代收发波束关联,而收发波束关联的公共标识则可以BPL公共标识进行描述。在现在或未来的标准中,收发波束关联的公共标识的定义、名称可能会有所改变,不过与本发明所述概念的技术本质一致的名称,均属于本发明实施例的保护范围。The carrier of the public identifier associated with the transceiver beam may be an antenna port number, such as a spatial quasi-co-location port (spatial QCLport), or may be a reference signal resource sequence number, such as a channel state information reference signal ( Channel State Information-Reference Signal (CSI-RS) port number or CSI-RS resource index. In the embodiment of the present invention, for the sake of brevity, a conceptual beam pairing (BPL) with a closer nature of the technology may be substituted for the transceiving beam association, and the public identifier of the transceiving beam association may be described by the BPL public identifier. In the current or future standards, the definition and name of the public identity associated with the transceiver beam may be changed, but the names consistent with the technical nature of the concept of the present invention are within the scope of protection of the embodiments of the present invention.
目前,系统无法保障基站下发的BPL公共标识一定能被UE成功接收,这样便可能会存在问题。假设UE没有接收到基站下发的BPL公共标识1,但接收到基站下发的波束扫描触发指令,此时基站照常执行波束扫描,UE也照常执行波束扫描,反馈扫描结果,但是基站和UE对这份扫描结果的“理解”出现了偏差。例如,基站将UE反馈的发送波束A与其配置下发的BPL公共标识1进行了关联,而UE则不会将接收波束a与BPL公共标识1进行关联,并且可能根本不知道这个公共标识。当之后基站要求UE监控这个新的BPL(发送波束A-接收波束a)时,UE不知道用哪个接收波束进行接收,该BPL无法使用。甚至当基站切换到这个新BPL的发送波束时,UE无法匹配,通信会直接中断。At present, the system cannot guarantee that the BPL public identity delivered by the base station can be successfully received by the UE, and thus there may be a problem. It is assumed that the UE does not receive the BPL public identity 1 delivered by the base station, but receives the beam scanning trigger command sent by the base station. At this time, the base station performs beam scanning as usual, and the UE performs beam scanning as usual to feed back the scanning result, but the base station and the UE pair There was a bias in the "understanding" of this scan. For example, the base station associates the transmit beam A fed back by the UE with the BPL public identity 1 delivered by the UE, and the UE does not associate the receive beam a with the BPL public identity 1, and may not know the public identity at all. When the base station subsequently requests the UE to monitor this new BPL (transmit beam A-receive beam a), the UE does not know which receive beam to use for reception, 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 the communication is directly interrupted.
类似这种基站和UE对同一个BPL公共标识有着不同的“理解”的情况在BPL公共标识的建立和维护过程中均可能会出现。鉴于此,本发明实施例提供一种波束管理方法,可以实现基站与UE针对BPL公共标识的握手,保证多条BPL的正确建立和维护,进而可以提高基于波束接入系统的通信鲁棒性。Similar situations in which such base stations and UEs 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, the embodiment of the present invention provides a beam management method, which can implement a handshake between a base station and a UE for a BPL public identity, and ensure correct establishment and maintenance of multiple BPLs, thereby improving communication robustness based on the beam access system.
下面将结合附图2-附图6对本发明实施例提供的波束管理方法进行详细介绍。The beam management method provided by the embodiment of the present invention will be described in detail below with reference to FIG. 2 to FIG.

The association between the two, that is, the beam pairing relationship. A public 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), and the at least one public identifier may be indicated by an identifier indicating bit in the DCI, where the number of bits of the identifier indicating bit may be paired with a beam The specific value is related to the specific case, and is not limited in the embodiment of the present invention. For example, the identifier indicating bit uses 2 bits to indicate the public identifier of the beam pairing relationship.
在一种可能实现的方式中,所述DCI还携带波束扫描触发指令,所述波束扫描触发指令可占用1比特,例如,该比特置“1”时表示携带所述波束扫描触发指令,该比特置“0”时表示不携带所述波束扫描触发指令。所述网络设备在发送携带所述至少一个公共标识和所述波束扫描触发指令的所述DCI时,可执行波束扫描,即基站侧执行波束扫描。所述用户设备在接收到携带所述至少一个公共标识和所述波束扫描触发指令的所述DCI时,可执行波束扫描,即UE侧根据所述波束扫描触发指令执行波束扫描。In a possible implementation manner, the DCI further carries a beam scanning triggering instruction, where the beam scanning triggering instruction can occupy 1 bit, for example, when the bit is set to “1”, the beam scanning triggering instruction is carried, and the bit is carried. When "0" is set, it means that the beam scan triggering instruction is not carried. When the network device sends the DCI carrying the at least one common identifier and the beam scan triggering command, the network device may perform beam scanning, that is, the base station side performs beam scanning. The user equipment may perform beam scanning when receiving the DCI carrying the at least one common identifier and the beam scanning triggering instruction, that is, the UE side performs beam scanning according to the beam scanning triggering instruction.

Optionally, the at least one public identifier is combined with the beam scan triggering instruction to be the same instruction, and the instruction may indicate the at least one public identifier and may trigger a beam scan.
在一种可能实现的方式中,所述DCI不携带波束扫描触发指令,但是所述至少一个公共标识可以触发波束扫描,即所述网络设备在发送携带所述至少一个公共标识的所述DCI时,可执行波束扫描,即基站侧执行波束扫描。所述用户设备在接收到携带所述至少一个公共标识的所述DCI时,可执行波束扫描,即UE侧根据所述至少一个公共标识执行波束扫描。换言之,该种可能实现的方式中,所述至少一个公共标识除了指示标识外,还用于触发波束扫描,相当于在所述至少一个公共标识中融合了所述波束扫描触发指令的功能,可以节省DCI开销。In a possible implementation manner, the DCI does not carry a beam scan triggering instruction, but the at least one public identifier may trigger a beam scan, that is, when the network device sends the DCI carrying the at least one public identifier. The beam scanning can be performed, that is, the base station side performs beam scanning. When receiving the DCI carrying the at least one public identifier, the user equipment may perform beam scanning, that is, the UE side performs beam scanning according to the at least one public identifier. In other words, in the possible implementation manner, the at least one public identifier is used to trigger beam scanning in addition to the indication identifier, which is equivalent to the function of combining the beam scan triggering instruction in the at least one public identifier. Save DCI overhead.
上述两种可能实现的方式中,所述网络设备执行的波束扫描、所述用户设备执行的波束扫描可以是非周期波束扫描。非周期波束扫描可以对应于NR下行波束管理的P-2阶段或P-3阶段。非周期(nonperiodic)可以为半持续性(semi-persistent)或不定期(aperiodic)。In the above two possible implementation manners, the beam scanning performed by the network device and the beam scanning performed by the user equipment may be aperiodic beam scanning. The aperiodic beam scan may correspond to the P-2 phase or the P-3 phase of the NR downlink beam management. Nonperiodic can be semi-persistent or aperiodic.
所述网络设备可通过物理下行控制信道(Physical Downlink Control Channel,PDCCH)向所述用户设备发送所述DCI。所述DCI在PDCCH中的发送流程可包括循环冗余码校验(Cyclic Redundancy Check,CRC)、加扰、信道编码、速率匹配、交织等过程。The network device may send the DCI to the user equipment by using a Physical Downlink Control Channel (PDCCH).

步骤S202:所述用户设备监听所述网络设备发送的携带所述至少一个公共标识的所述第一信息;Step S202: The user equipment listens to the first information that is sent by the network device and carries the at least one public identifier.
具体地,由于影响无线信道传输的因素比较多而杂,所述网络设备发送的所述第一信息,所述用户设备可能会接收到,也可能会接收不到,因此所述用户设备需要监听所述网络设备发送的携带所述至少一个公共标识的所述第一信息。Specifically, the first information sent by the network device may be received by the user equipment, or may not be received, because the factors affecting the transmission of the wireless channel are relatively large. Therefore, the user equipment needs to be monitored. The first information that is sent by the network device to carry the at least one public identifier.
在一种可能实现的方式中,所述用户设备在接收到所述第一信息时,对所述第一信息进行解码或CRC等处理时出错,未能获得所述第一信息,自然也未获得所述至少一个公共标识,此时可确定所述用户设备未监听到所述至少一个公共标识。In a possible implementation manner, when the user equipment receives the first information, when the first information is decoded or the CRC is processed, an error occurs, and the first information is not obtained, and naturally Obtaining the at least one public identifier, and determining that the user equipment does not listen to the at least one public identifier.
在一种可能实现的方式中,所述用户设备获得了所述第一信息,但是未获得所述至少一个公共标识,此时可确定所述用户设备未监听到所述至少一个公共标识。In a possible implementation manner, the user equipment obtains the first information, but does not obtain the at least one public identifier, and may determine that the user equipment does not listen to the at least one public identifier.
在一种可能实现的方式中,所述用户设备未监听到所述第一信息,那么也就未监听到所述至少一个公共标识。In a possible implementation manner, the user equipment does not listen to the first information, and then the at least one public identifier is not monitored.
所述用户设备在接收到所述第一信息,且能够获得所述第一信息以及所述至少一个公共标识的情况下,可确定所述用户设备监听到所述至少一个公共标识。The user equipment may determine that the user equipment is listening to the at least one public identifier if the first information is received and the first information and the at least one public identifier are available.

Sending, by the user equipment, the second information that carries the default identifier to the network device, where the user equipment does not listen to the at least one public identifier, where the default identifier indicates that the user equipment does not listen to the at least one Public identity. The case where the user equipment does not listen to the at least one public identity may be determined according to the manner in which three possible implementations are listed in step S202.
其中,所述第二信息可以是上行控制信息(Uplink Control Information,UCI)。所述UCI中可增加1比特的指示位来指示所述接收成功标识或所述缺省标识,例如,该指示位为“1”时表示所述接收成功标识,该指示位为“0”时表示所述缺省标识。该指示位所占用的1比特可以为独立的1比特,也可以与其它上报信息结合。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 identifier or the default identifier. For example, when the indication bit is “1”, the reception success identifier is indicated, and when the indication bit is “0” Represents the default identity. The 1 bit occupied by the indicator bit can be an independent 1 bit, and can also be combined with other reported information.
需要说明的是,所述用户设备只有在监听到所述至少一个公共标识的情况下,才向所述网络设备发送携带所述接收成功标识的所述第二信息,在其他情况下,所述用户设备默认向所述网络设备发送携带所述缺省标识的所述第二信息。It should be noted that, the user equipment sends the second information carrying the receiving success identifier to the network device only if the at least one public identifier is monitored, in other cases, the The user equipment sends the second information carrying the default identifier to the network device by default.

The user equipment sends the scan result to the network device. And the user equipment may send the second information that carries the receiving success identifier to the network device, because the user equipment monitors the at least one public identifier, and the at least one public identifier may trigger a beam scan. And the scanning result, the two can be sent simultaneously, or can be sent in sequential order.
