Description

一种无线通信网络中的指示波束信息的方法和设备Method and equipment for indicating beam information in wireless communication network 技术领域Technical field
本申请涉及通信领域，并且更具体地，涉及一种指示波束信息的方法和设备。The present application relates to the field of communications, and more particularly, to a method and device for indicating beam information.
背景技术Background technique
在现有的无线通信网络(如2G、3G和4G网络)中，通信***的工作频段都在6GHz以下的频率范围中，而在这个频率范围内可用的工作频段越来越少，无法满足日益增长的通信需求。相反，6GHz以上的频率范围却有大量未充分利用的频段。因此，业界正在研究和开发工作频段在6GHz以上的下一代(如5G)无线通信网络，以提供超高速的数据通信业务。在6GHz以上的频率范围，可用于下一代无线通信网络的频段包括位于28GHz、39GHz、60GHz、73GHz等处的频段。因其工作频段在6GHz以上，下一代无线通信网络具有高频通信***的显著特点，如大带宽和高集成天线阵列，从而容易实现到较高的吞吐量。In existing wireless communication networks (such as 2G, 3G, and 4G networks), the operating frequency bands of communication systems are in the frequency range below 6GHz, and the working frequency bands available in this frequency range are becoming less and less, which cannot meet the increasing Increasing demand for communications. In contrast, the frequency range above 6GHz has a large number of underutilized frequency bands. Therefore, the industry is researching and developing next-generation (such as 5G) wireless communication networks operating at frequencies above 6 GHz to provide ultra-high-speed data communication services. In the frequency range above 6GHz, the frequency bands that can be used for next-generation wireless communication networks include frequency bands located at 28GHz, 39GHz, 60GHz, 73GHz, and so on. Because its operating frequency band is above 6GHz, the next-generation wireless communication network has significant characteristics of high-frequency communication systems, such as large bandwidth and highly integrated antenna arrays, thereby easily achieving higher throughput.
无线资源管理测量(radio resource management measurement，RRM measurement)是为了终端设备进行功率控制、调度、小区选择、小区重选、切换、无线链路检测、连接建立和重建等而进行的测量。5G NR(new radio)中可以使用SS/PBCH block(synchronization signal/physical broadcast channel block，同步信号/物理广播信道块，简称同步信号块，SSB)或CSI-RS(channel state information reference signal，信道状态信息参考信号)进行RRM测量。使用SSB进行RRM测量时，测量的配置参数可以有SMTC(SS block based RRM measurement timing configuration，基于同步信号块的RRM测量的时间配置)的周期，SMTC的长度，SMTC的偏移等。对于一个子载波，只需要配置一个SMTC。但是SSB在基站里是基于波束进行发送，不同的波束对应不同的覆盖区域，也对应不同的SSB。高频***中，在配置的SMTC窗内，终端设备需要检测所有波束，由于波束数量较多，造成功耗较大。Radio resource management measurement (radio resource management measurement, RRM measurement) is a measurement performed for terminal equipment to perform power control, scheduling, cell selection, cell reselection, handover, wireless link detection, connection establishment, and reconstruction. 5GNR (new radio) can use SS / PBCH block (synchronization signal / physical broadcast channel channel block, synchronization signal / physical broadcast channel block, referred to as synchronization signal block, SSB) or CSI-RS (channel state state information signal, channel state Information Reference Signal) for RRM measurement. When using the SSB for RRM measurement, the measurement configuration parameters can include the period of SMTC (SS block-based RRM measurement configuration, time configuration for RRM measurement based on synchronization signal block), the length of SMTC, and the offset of SMTC. For one subcarrier, only one SMTC needs to be configured. However, the SSB is transmitted based on the beam in the base station. Different beams correspond to different coverage areas and also correspond to different SSBs. In a high-frequency system, in the configured SMTC window, the terminal device needs to detect all beams. Due to the large number of beams, the power consumption is large.

例如：终端设备可以根据所述关联关系，确定所述终端设备对应的SSB的关联SSB，并对所述相关联SSB进行RRM测量，不关联的SSB不需要进行RRM测量；或者对所述终端设备对应的SSB以及所述相关联SSB进行RRM测量，相关联SSB为一个或多个，通常为多个。For example, the terminal device may determine the associated SSB of the SSB corresponding to the terminal device according to the association relationship, and perform RRM measurement on the associated SSB, and RRM measurement is not required for the unassociated SSB; or the terminal device The corresponding SSB and the associated SSB perform RRM measurement. There are one or more associated SSBs, usually multiple.
结合上述方案，在其他方案中，在所述多个SSB之间的关联关系也可以包括一个SSB与所述多个SSB中其它SSB之间的关联关系；In combination with the above scheme, in other schemes, the association relationship between the multiple SSBs may also include the association relationship between one SSB and other SSBs in the multiple SSBs;

例如：如果SSB1与SSB2有关联关系，则SSB1与SSB2相邻，实际表示SSB1对应的波束与SSB2对应的波束相邻。For example: if SSB1 and SSB2 are related, SSB1 is adjacent to SSB2, which actually means that the beam corresponding to SSB1 is adjacent to the beam corresponding to SSB2.
另一个例子中，所述指示信息可以指示部分SSB的相邻SSB；或部分SSB中的每个SSB与其它SSB是否相邻。In another example, the indication information may indicate a neighboring SSB of a part of the SSB; or whether each SSB in the part of the SSB is adjacent to another SSB.

多个SSB之间的关联关系可以一起下发，也可以分多次进行下发，例如：每次下发一个SSB与其它SSB的关联关系，或一次下发部分SSB与其它SSB的关联关系，或一次下发所有SSB与其它SSB的关联关系。The association relationship between multiple SSBs can be issued together, or it can be issued multiple times, for example: each time the association relationship between an SSB and other SSBs, or the association relationship between some SSBs and other SSBs, Or, the association relationship between all SSBs and other SSBs is issued at one time.
另外，如果所述SSB的数目大于或等于预设的门限，则采用分组方式发送所述多个SSB的指示信息，则所述指示信息为分组方式指示信息。如果所述SSB的数目小于或等于预设的门限，则不需要分组，将所有SSB看成一组，直接发送所述指示信息，所述指示信息指示各个SSB的相邻SSB。In addition, if the number of SSBs is greater than or equal to a preset threshold, the indication information of the multiple SSBs is sent in a grouping manner, and the instruction information is grouping-type indication information. If the number of SSBs is less than or equal to a preset threshold, grouping is not required, and all SSBs are regarded as a group, and the indication information is directly sent, and the indication information indicates a neighboring SSB of each SSB.

所述分组方式根据实际发送或者可能发送的SSB数目确定。The grouping mode is determined according to the number of SSBs actually transmitted or possibly transmitted.
在另一个实施方式中，由于一个波束可以对应一个或多个SSB，也可以对应一个或多个CSI-RS，因此上述方案中多个SSB之间的关联关系也可以为多个波束之间的关联关系或多个CSI-RS之间的关联关系。In another embodiment, since one beam may correspond to one or more SSBs and one or more CSI-RSs, the association relationship between multiple SSBs in the foregoing solution may also be between multiple beams.

为便于理解本申请实施例，首先结合图1详细说明适用于本申请实施例的通信***。In order to facilitate understanding of the embodiments of the present application, a communication system applicable to the embodiments of the present application will be described in detail with reference to FIG. 1.
图1是适用于本申请实施例的通信***100的示意图。如图1所示，该通信***100包括至少一个网络设备110和至少一个终端设备120。在通信***100中，终端设备和网络设备可以通过波束管理过程获得通信较优的一个或多个波束对，波束对为<Bx，B’x>以及<By,B’y>，其中Bx代表网络设备的发送波束，B’x代表终端设备的接收波束，By代表终端设备的发送波束，B’y代表网络设备的接收波束。例如，参见图1，网络设备的发送波束#1和终端设备的接收波束#0为一个波束对，网络设备的发送波束#2和终端设备的接收波束#2为一个波束对。终端设备的发送波束#0和网络设备的接收波束#1为一个波束对，终端设备的发送波束#1和网络设备的接收波束#2为一个波束对。FIG. 1 is a schematic diagram of a communication system 100 applicable to an embodiment of the present application. As shown in FIG. 1, the communication system 100 includes at least one network device 110 and at least one terminal device 120. In the communication system 100, the terminal device and the network device can obtain one or more beam pairs with better communication through a beam management process. The beam pairs are <Bx, B'x> and <By, B'y>, where Bx represents The transmission beam of the network device, B'x represents the reception beam of the terminal device, By represents the transmission beam of the terminal device, and B'y represents the reception beam of the network device. For example, referring to FIG. 1, the transmission beam # 1 of the network device and the reception beam # 0 of the terminal device are one beam pair, and the transmission beam # 2 of the network device and the reception beam # 2 of the terminal device are one beam pair. The transmitting beam # 0 of the terminal device and the receiving beam # 1 of the network device are one beam pair, and the transmitting beam # 1 of the terminal device and the receiving beam # 2 of the network device are one beam pair.
在通信***100中需要终端设备120和网络设备110的波束对齐才能进行正常的通信。由于终端设备和网络设备都能各自朝向多个波束方向，因此进行通信的前提是需要有正确的波束指示。具体来讲，在下行通信中，网络设备需要通知终端设备应该使用什么接收波束接收接下来网络设备发送的信号，或者通知终端设备接下来网络设备发送的信号是使用什么发送波束发送的。在上行通信中，网络设备需要通知终端设备应该使用什么发送波束发送上行信号，或者通知终端设备网络设备会使用什么样的接收波束来接收终端发出的信号。比如，在下行传输中，网络设备可以通知终端设备该网络设备使用发送波束#1进行传输，那么终端设备需要使用接收波束#0进行接收。或者，网络设备使用发送波束#1进行传输，并且通知终端设备使用接收波束#0进行接收。再如，在上行传输中，网络设备可以通知终端设备使用发送波束#0进行传输，那么网络设备将使用接收波束#1进行接收。或者，网络设备可以通知该终端设备自身使用的接收波束为接收波束#1，从而终端设备需要使用发送波束#0进行传输。In the communication system 100, the beam alignment of the terminal device 120 and the network device 110 is required to perform normal communication. Since the terminal equipment and the network equipment can each face multiple beam directions, the premise of communication is that a correct beam indication is required. Specifically, in the downlink communication, the network device needs to notify the terminal device of what receiving beam should be used to receive the next signal sent by the network device, or notify the terminal device of what transmission beam to use for the next signal sent by the network device. In the uplink communication, the network device needs to notify the terminal device of which transmission beam should be used to send the uplink signal, or notify the terminal device of which receiving beam the network device will use to receive the signal from the terminal. For example, in downlink transmission, the network device may notify the terminal device that the network device uses transmission beam # 1 for transmission, and then the terminal device needs to use reception beam # 0 for reception. Alternatively, the network device uses the transmission beam # 1 for transmission, and notifies the terminal device to use the reception beam # 0 for reception. As another example, in uplink transmission, the network device may notify the terminal device to use the transmission beam # 0 for transmission, and then the network device will use the reception beam # 1 for reception. Alternatively, the network device may notify the terminal device that the receiving beam used by the terminal device is the receiving beam # 1, so that the terminal device needs to use the transmitting beam # 0 for transmission.
为便于理解本申请实施例，下面对本申请中涉及的几个术语做简单介绍。In order to facilitate understanding of the embodiments of the present application, several terms involved in the present application are briefly introduced below.

Beam: A beam is a communication resource. The beam can be a wide beam, or a narrow beam, or another type of beam. The beam forming technology may be beamforming or other technical means. The beamforming technology may specifically be a digital beamforming technology, an analog beamforming technology, or a hybrid digital / analog beamforming technology. Different beams can be considered as different resources. The same information or different information can be transmitted through different beams. Optionally, multiple beams having the same or similar communication characteristics may be considered as one beam. A beam may include one or more antenna ports for transmitting data channels, control channels and sounding signals.
波束，也可以理解为空间资源，可以是指具有能量传输指向性的发送或接收预编码向量。能量传输指向性可以指在一定空间位置内，接收经过该预编码向量进行预编码处理后的信号具有较好的接收功率，如满足接收解调信噪比等，能量传输指向性也可以指通过该预编码向量接收来自不同空间位置发送的相同信号具有不同的接收功率。同一设备(例如网络设备或终端设备)可以有不同的预编码向量，不同的设备也可以有不同的预编码向量，即对应不同的波束，针对设备的配置或者能力，一个设备在同一时刻可以使用多个不同的预编码向量中的一个或者多个，即同时可以形成一个波束或者多个波束。从发射和接收两个角度出发，波束可以分为发射波束和接收波束。A beam can also be understood as a spatial resource, which can refer to sending or receiving a precoding vector with directivity for energy transmission. The directivity of energy transmission can refer to that within a certain spatial position, the signal after receiving the precoding vector for precoding processing has better receiving power, such as meeting the receiving demodulation signal-to-noise ratio, etc. The directivity of energy transmission can also refer to The precoding vector receives the same signal sent from different spatial locations with different received power. The same device (such as a network device or terminal device) can have different precoding vectors, and different devices can also have different precoding vectors, that is, corresponding to different beams. According to the configuration or capability of the device, one device can be used at the same time.

Transmitting a signal between a transmitting beam and a receiving beam having a beam pairing relationship can obtain a large beamforming gain.
在一种实现方式中，发送端和接收端可以通过波束训练来获得波束配对关系。具体地，发送端可通过波束扫描的方式发送参考信号，接收端也可通过波束扫描的方式接收参考信号。具体地，发送端可通过波束赋形的方式在空间形成不同指向性的波束，并可以在多个具有不同指向性的波束上轮询，以通过不同指向性的波束将参考信号发射出去，使得参考信号在发射波束所指向的方向上发射参考信号的功率可以达到最大。接收端也可通过波束赋形的方式在空间形成不同指向性的波束，并可以在多个具有不同指向性的波束上轮询，以通过不同指向性的波束接收参考信号，使得该接收端接收参考信号的功率在接收波束所指向的方向上可以达到最大。In an implementation manner, the transmitting end and the receiving end may obtain a beam pairing relationship through beam training. Specifically, the transmitting end may send the reference signal in a beam scanning manner, and the receiving end may also receive the reference signal in a beam scanning manner. Specifically, the transmitting end may form beams with different directivity in space by means of beamforming, and may poll on multiple beams with different directivity, so as to transmit the reference signal through beams with different directivity, so that The power of the reference signal to transmit the reference signal in the direction pointed by the transmission beam can reach the maximum. The receiving end can also form beams with different directivity in the space by means of beamforming, and can poll on multiple beams with different directivity to receive reference signals through the beams with different directivity, so that the receiving end receives The power of the reference signal can be maximized in the direction pointed by the receiving beam.
3、参考信号与参考信号资源：参考信号可用于信道测量或者信道估计等。参考信号资源可用于配置参考信号的传输属性，例如，时频资源位置、端口映射关系、功率因子以及扰码等，具体可参考现有技术。发送端设备可基于参考信号资源发送参考信号，接收端设备可基于参考信号资源接收参考信号。3. Reference signal and reference signal resources: Reference signals can be used for channel measurement or channel estimation. The reference signal resource can be used to configure transmission attributes of the reference signal, such as the position of the time-frequency resource, the port mapping relationship, the power factor, and the scrambling code. For details, refer to the prior art. The transmitting device may send the reference signal based on the reference signal resource, and the receiving device may receive the reference signal based on the reference signal resource.
本申请中涉及的信道测量也包括波束测量，即通过测量参考信号获得波束质量信息，用于衡量波束质量的参数包括参考信号接收功率(reference signal receiving power，RSRP)，但不限于此。例如，波束质量也可以通过参考信号接收质量(reference signal receiving quality，RSRQ)，信噪比(signal-noise ratio，SNR)，信号与干扰噪声比(signal to interference plus noise ratio，SINR)，块误码率(block error rate，BLER)，信号质量指示(channel quality indicator，CQI)等参数衡量。本申请实施例中，为方便说明，在未作出特别说明的情况下，所涉及的信道测量可以视为波束测量。The channel measurement involved in this application also includes beam measurement, that is, obtaining beam quality information by measuring a reference signal.

For example, the beam quality can also be determined by reference signal reception quality (RSRQ), signal-noise ratio (SNR), signal to interference plus noise ratio (SINR), block error It is measured by parameters such as code rate (block error rate, BLER), signal quality indicator (channel quality indicator, CQI). In the embodiments of the present application, for the convenience of description, the channel measurement involved may be regarded as a beam measurement without a special description.

(SS / PBCH block source) can be referred to as SSB source for short.
为了区分不同的参考信号资源，每个参考信号资源可对应于一个参考信号资源的标识，例如，CSI-RS资源标识(CSI-RS resource indicator，CRI)、SSB资源标识(SSB resource indicator，SSBRI)、SRS资源索引(SRS resource index，SRI)。其中，SSB资源标识也可以称为SSB标识(SSB index)。In order to distinguish different reference signal resources, each reference signal resource may correspond to an identifier of a reference signal resource, for example, CSI-RS resource identifier (CRI), SSB resource identifier (SSB resource identifier).

The uplink signal may be one or more of the following: uplink random access sequence, uplink sounding reference signal (SRS), uplink control channel demodulation reference signal, uplink data channel demodulation reference signal, uplink phase Either noise tracking signal.
波束指示信息还可以体现为传输配置编号(Transmission Configuration Index，TCI)或者TCI状态。一个TCI状态包括一个或多个准共址(quasi-co-location，QCL)信息，每一个QCL信息包括一个参考信号(或同步信号块)的ID和一种QCL类型。例如：终端设备可以需要根据网络设备指示的TCI状态(通常由物理下行控制信道(physical downlink control channel，PDCCH)携带)来确定接收物理下行共享信道(physical downlink shared channel，PDSCH)的波束。The beam indication information may also be expressed as a Transmission Configuration Number (TCI) or TCI status. A TCI state includes one or more quasi-co-location (QCL) information, and each QCL information includes an ID of a reference signal (or a synchronization signal block) and a QCL type. For example, a terminal device may need to determine a beam receiving a physical downlink shared channel (PDSCH) according to a TCI status (usually carried by a physical downlink control channel (PDCCH)) indicated by a network device.
5、准共址(quasi-co-location，QCL)：或者称准同位。准同位关系用于表示多个资源之间具有一个或多个相同或者相类似的通信特征，对于具有同位关系的多个资源，可以采用相同或者类似的通信配置。具体的。具有QCL关系的天线端口对应的信号中具有相同的参数，或者，一个天线端口的参数(也可以称为QCL参数)可用于确定与该天线端口具有QCL关系的另一个天线端口的参数，或者，两个天线端口具有相同的参数，或者，两个天线端口间的参数差小于某阈值。其中，所述参数可以包括以下一项或多项：时延扩展(delay spread)，多普勒扩展(Doppler spread)，多普勒频移(Doppler shift)，平均时延(average delay)，平均增益，空间接收参数(spatial Rx parameters)。其中，空间接收参数可以包括以下的一项或多项：到达角(angle of arrival，AOA)、平均AOA、AOA扩展、离开角(angle of departure，AOD)、平均离开角AOD、AOD扩展、接收天线空间相关性参数、发送天线空间相关性参数、发射波束、接收波束以及资源标识。5. Quasi-co-location (QCL): Or quasi-co-location. A quasi-parity relationship is used to indicate that multiple resources have one or more identical or similar communication characteristics. For multiple resources having a parity relationship, the same or similar communication configuration can be adopted. specific. A signal corresponding to an antenna port having a QCL relationship has the same parameter, or a parameter of one antenna port (also called a QCL parameter) may be used to determine a parameter of another antenna port having a QCL relationship with the antenna port, or, The two antenna ports have the same parameters, or the parameter difference between the two antenna ports is less than a certain threshold. The parameters may include one or more of the following: delay spread, Doppler spread, Doppler shift, average delay, average Gain, spatial Rx parameters. Among them, the space receiving parameters may include one or more of the following: angle of arrival (AOA), average AOA, AOA extension, angle of departure (AOD), average departure angle AOD, AOD extension, reception Antenna spatial correlation parameters, transmitting antenna spatial correlation parameters, transmit beam, receive beam, and resource identification.
空域准同位(spatial QCL)：spatial QCL可以认为是QCL的一种类型。对于spatial，可以分别从发送端或接收端角度进行理解：从发送端来看，如果两个天线端口是空域准同位的，即是指这两个天线端口的对应的波束方向在空间上是一致的；从接收端来看，如果两个天线端口是空域准同位的，则是指接收端能够在相同的波束方向上接收到这两个天线端口发送的信号。Spatial QCL: Spatial QCL can be considered as a type of QCL. For spatial, it can be understood from the perspective of the transmitting end or the receiving end: From the perspective of the transmitting end, if the two antenna ports are quasi-parity in the airspace, it means that the corresponding beam directions of the two antenna ports are spatially consistent. From the perspective of the receiving end, if the two antenna ports are quasi co-located in the airspace, it means that the receiving end can receive the signals sent by the two antenna ports in the same beam direction.
6、准同位假设(QCL assumption)：是指假设两个端口之间是否具有QCL关系。准同位假设的配置和指示可以用来帮助接收端进行信号的接收和解调。例如接收端能假设A端口和B端口具有QCL关系，即可以将A端口上测得的信号的大尺度参数用于B端口上的信号测量和解调。大尺度参数可以包括上述的天线端口的参数。6. Quasi-parity hypothesis (QCL assumption): It is assumed whether there is a QCL relationship between two ports. The configuration and indication of the quasi-parity hypothesis can be used to help the receiving end to receive and demodulate signals. For example, the receiving end can assume that the A port and the B port have a QCL relationship, that is, the large-scale parameters of the signal measured on the A port can be used for signal measurement and demodulation on the B port. The large-scale parameters may include the parameters of the antenna port described above.
7、模拟波束成型，可以通过射频实现。例如，一个射频链路(RF chain)通过移相器来调整相位，从而控制模拟波束方向的改变。因此，一个RF chain在同一时刻只能打出一个模拟波束。7. Analog beamforming can be achieved by radio frequency. For example, a radio frequency (RF) chain adjusts the phase through a phase shifter to control the change of the direction of the analog beam. Therefore, an RF chain can only fire one analog beam at a time.

网络设备向终端设备发送指示信息，所述指示信息用于指示多个同步信号块SSB之间的关联关系，所述多个SSB之间的关联关系包括每个SSB与其它SSB之间的关联关系；终端设备接收到该指示信息后，便可以根据所述关联关系执行相应的通信操作，例如：The network device sends instruction information to the terminal device, where the instruction information is used to indicate an association relationship between multiple synchronization signal blocks SSBs, and the association relationship between the multiple SSBs includes an association relationship between each SSB and other SSBs ; After receiving the instruction information, the terminal device can perform corresponding communication operations according to the association relationship, for example:
RRM测量要对波束对应的SSB进行测量，一个载波或频段需要配置一个SMTC。但是高频通信***中，SSB在基站里面发送是基于波束发送的，一个波束对应至少一个SSB，在一个SMTC窗内，终端设备需要测量多个波束对应的SSB，造成终端的功耗较大。For RRM measurement, to measure the SSB corresponding to the beam, an SMTC needs to be configured for one carrier or frequency band. However, in a high-frequency communication system, SSB transmission in a base station is based on beam transmission. One beam corresponds to at least one SSB. Within an SMTC window, a terminal device needs to measure the SSBs corresponding to multiple beams, resulting in large power consumption of the terminal.
终端设备获知多个SSB之间的关联关系，进行RRM测量时，便可以减少波束检测的数量，从而减少终端设备的功耗，下面将结合附图详细说明本申请实施例。The terminal device learns the association relationship between multiple SSBs, and when performing RRM measurement, it can reduce the number of beam detections, thereby reducing the power consumption of the terminal device. The embodiments of the present application will be described in detail below with reference to the accompanying drawings.
图2是从设备交互的角度示出的指示波束信息的示意性流程图。应理解，在本申请实施例中，以终端设备和网络设备作为执行主体为例，对指示波束信息的方法进行说明。作为示例而非限定，执行主体也可以是应用于终端设备的芯片和应用于网络设备的芯片。FIG. 2 is a schematic flowchart of indicating beam information from a perspective of device interaction. It should be understood that, in the embodiment of the present application, a terminal device and a network device are used as execution subjects as an example to describe a method for indicating beam information. By way of example and not limitation, the execution subject may also be a chip applied to a terminal device and a chip applied to a network device.
S101，网络设备向终端设备发送指示信息，所述指示信息携带多个SSB之间的关联关系。S101. A network device sends instruction information to a terminal device, where the instruction information carries an association relationship between multiple SSBs.
多个SSB之间的关联关系可以包括各个SSB与其它SSB的关联关系，例如：每个SSB关联的SSB是哪些，由于一个波束可以对应一个或多个SSB，因此指示信息可以表示每个波束的相关联波束或相邻波束，也就是每个SSB的相关联SSB或相邻SSB，或称为每个SSB具有关联关系的SSB。The association relationship between multiple SSBs may include the association relationship between each SSB and other SSBs, for example, which SSBs are associated with each SSB. Since one beam can correspond to one or more SSBs, the indication information can indicate the An associated beam or adjacent beam, that is, an associated SSB or adjacent SSB of each SSB, or an SSB having an associated relationship with each SSB.
另一例子中，指示信息也可以指示某一个SSB与其它SSB的关联关系，或者多个SSB中部分SSB与其它SSB的关联关系。In another example, the indication information may also indicate an association relationship between a certain SSB and other SSBs, or an association relationship between some SSBs in other SSBs and other SSBs.
综上所述，所述关联关系表示每个SSB对应的波束与其它SSB对应的波束是否相邻。本申请中，某个SSB与另一个SSB相邻，其含义为该SSB对应的波束与另一个SSB对应的波束相邻。也可以称为某个SSB与另一个SSB相关联或具有关联关系。In summary, the association relationship indicates whether a beam corresponding to each SSB is adjacent to a beam corresponding to another SSB. In this application, an SSB is adjacent to another SSB, which means that a beam corresponding to the SSB is adjacent to a beam corresponding to another SSB. It can also be said that an SSB is associated with or has an association relationship with another SSB.
S102，终端设备接收到网络设备下发的指示消息后，获知各个SSB之间的关联关系，并根据各个SSB之间的关联关系进行相关操作。S102. After receiving the instruction message issued by the network device, the terminal device learns the association relationship between the SSBs and performs related operations according to the association relationship between the SSBs.
终端设备获知各个SSB之间的关联关系，便可以确定某个SSB的相邻SSB是哪些，例如，可以根据上述关联关系确定该终端设备对应的SSB关联的SSB，并对所述关联的SSB进行相关的通信操作。After the terminal device learns the association relationship between the SSBs, it can determine which SSBs are adjacent to the SSB. For example, the SSB associated with the SSB corresponding to the terminal device can be determined according to the above association relationship, and the associated SSB is performed. Related communication operations.
所述终端设备对应的SSB可以为终端设备当前所使用的SSB，例如：当前所使用的SSB表示终端设备使用与该SSB相同的参数去接收其他信息，即所述的其他信息与该SSB具有QCL关系。所述的QCL关系可以为两个信号在多普勒扩展，多普勒移动，平均增益，平均时延，时延扩展和接收参数中的一项或多项中具有准共址的关系。The SSB corresponding to the terminal device may be the SSB currently used by the terminal device. For example, the currently used SSB indicates that the terminal device uses the same parameters as the SSB to receive other information, that is, the other information has a QCL with the SSB. relationship. The QCL relationship may be a quasi co-location relationship between two signals in one or more of Doppler spread, Doppler shift, average gain, average delay, delay spread, and reception parameters.
例如：终端设备可以获知每个SSB的相关联SSB，即相邻SSB，或称为具有关联关系的SSB，由于SSB与波束对应，因此可以获知每个波束的相邻波束，并可以根据当前波束的相邻波束执行相关的操作，即，在当前SSB的相邻SSB进行相关的通信操作；每个SSB的相邻SSB可以为一个或多个。For example, the terminal device can learn the associated SSB of each SSB, that is, the adjacent SSB, or the SSB with an association relationship. Since the SSB corresponds to the beam, it can learn the adjacent beam of each beam, and can learn the current beam according to the current beam. The neighboring beams of the SSB perform related operations, that is, perform related communication operations on neighboring SSBs of the current SSB; the neighboring SSBs of each SSB may be one or more.
相关的通信操作可以是进行RRM测量，寻呼消息的接收，SSB的同步，或***消息的接收等。Related communication operations may be RRM measurement, paging message reception, SSB synchronization, or system message reception.
比如：如果终端设备要进行RRM测量，则只需要测量当前SSB的相邻SSB(当然还可以测量当前SSB)，不相邻的SSB不需要进行测量，减少了测量的开销。当前SSB指终端设备对应的SSB，或终端设备处于该SSB对应的波束。当前SSB也称为终端设备使用的SSB，测量相邻SSB可以测量部分或全部。For example, if the terminal device is to perform RRM measurement, it only needs to measure the neighboring SSB of the current SSB (of course, it can also measure the current SSB). Non-adjacent SSBs do not need to be measured, which reduces the measurement overhead. The current SSB refers to the SSB corresponding to the terminal device, or the terminal device is in the beam corresponding to the SSB. The current SSB is also referred to as the SSB used by the terminal device, and measurement of neighboring SSBs can measure part or all of it.
同理，也可以只在当前SSB的相邻SSB(或相邻SSB以及当前SSB)进行寻呼消息的接收，SSB的同步，或***消息的接收等操作，不相邻的SSB不需要进行相关通信操作，从而节省了相关的开销。In the same way, you can also perform operations such as receiving paging messages, synchronizing SSBs, or receiving system messages only on neighboring SSBs (or neighboring SSBs and the current SSB) of the current SSB. Non-adjacent SSBs do not need to be correlated. Communication operation, thus saving related overhead.
以下对指示信息的指示方式进行举例说明：The following describes the indication method of the instruction information as an example:
方法1，可以采用bitmap的方式指示各个SSB与多个SSB中其它SSB的关联关系。Method 1. A bitmap may be used to indicate the association relationship between each SSB and other SSBs in multiple SSBs.
如图3所示的波束0-15，假设一个波束对应一个SSB，总共需要SSB数目为16个，分别为SSB0-SSB15；其中SSB1，SSB6和SSB7与SSB0相邻，相邻表示具有关联关系。也就是说SSB0对应的波束与SSB1，SSB6和SSB7对应的波束相邻。如果用1表示相邻，0表示不相邻，针对SSB0，SSB0-SSB15的bitmap为：0100 0011 0000 0000，这种情况下，指示SSB0的关联关系需要16比特。如果SSB0本身不指示，则SSB1-SSB15的bitmap为：100 0011 0000 0000；表示与SSB0相邻的SSB为SSB1，SSB6和SSB7，这种情况下，指示SSB0的关联关系需要15个比特。As shown in the beams 0-15 shown in FIG. 3, it is assumed that one beam corresponds to one SSB, and a total of 16 SSBs are required, which are SSB0-SSB15; SSB1, SSB6, and SSB7 are adjacent to SSB0, and adjacent indicates an association relationship. In other words, the beam corresponding to SSB0 is adjacent to the beam corresponding to SSB1, SSB6, and SSB7. If 1 is used for adjacent and 0 is used for non-adjacent, the bitmap of SSB0-SSB15 for SSB0 is: 0100, 0011, 0000, and 0000. In this case, 16 bits are required to indicate the association relationship of SSB0. If SSB0 does not indicate it by itself, the bitmap of SSB1-SSB15 is: 100001100000000; indicates that the SSBs adjacent to SSB0 are SSB1, SSB6, and SSB7. In this case, 15 bits are required to indicate the association relationship of SSB0.
当然也可以用0表示相邻，1表示不相邻，则将上述bitmap的1改成0，0改成1即可。Of course, you can also use 0 to indicate adjacent and 1 to indicate non-adjacent, then change 1 in the above bitmap to 0 and 0 to 1.
当终端设备位于SSB0对应的波束覆盖范围的时候，根据上述指示信息，可以只对SSB1，SSB6和SSB7执行相关操作(当然还可以对SSB0执行相关操作)。When the terminal device is located in the beam coverage area corresponding to SSB0, according to the above instruction information, related operations can be performed only on SSB1, SSB6, and SSB7 (of course, related operations can also be performed on SSB0).
以RRM测量为例，当终端设备同步或者接收到SSB0的时候，可以只对SSB1-15中的SSB1，SSB6和SSB7中的部分或者全部进行RRM测量(当然也可以对SSB0进行RRM测量)。对于SSB2-SSB5、SSB8-SSB15可以不需要进行RRM测量，或者也可以取其中一部分进行RRM测量，本申请实施例不予限制。Taking RRM measurement as an example, when the terminal equipment is synchronized or receives SSB0, it can only perform RRM measurement on part or all of SSB1, SSB6, and SSB7 in SSB1-15 (of course, RRM measurement can also be performed on SSB0). For SSB2-SSB5 and SSB8-SSB15, RRM measurement may not be required, or some of them may be used for RRM measurement, which is not limited in the embodiment of the present application.
按上述方式，SSB1-SSB15分别对应的相邻SSB也可以分别用bitmap方式来指示。例如：SSB1对应的bitmap为1010 0111 0000 0000，表示SSB1的相邻SSB为SSB0，SSB2，SSB5，SSB6和SSB7；SSB9对应的bitmap为0000 0111 1010 0111，表示SSB9的相邻SSB为SSB5-7，SSB8，SSB10，SSB13-15。In the above manner, the adjacent SSBs corresponding to SSB1 to SSB15 may also be respectively indicated by a bitmap method. For example, the bitmap corresponding to SSB1 is 1010, 0111, 0000, 0000, which means that the adjacent SSBs of SSB1 are SSB0, SSB2, SSB5, SSB6, and SSB7; the bitmap corresponding to SSB9 is 0000, 0111, 1010, 1011, which means that the adjacent SSB of SSB9 is SSB5-7, SSB8, SSB10, SSB13-15.
网络设备可以采用上述bitmap的方式，将每个SSB与其它SSB的关联关系指示给终端设备。指示信息可以一次性下发，也可以分成多次进行下发。The network device may indicate the association relationship between each SSB and other SSBs to the terminal device by using the foregoing bitmap. The instruction information may be issued at one time, or may be delivered in multiple times.
上述指示方式简称为精确指示，即将每个SSB关联的其它SSB的信息采用bitmap的方式下发。The above indication method is referred to as an accurate indication for short, that is, the information of other SSBs associated with each SSB is delivered in a bitmap manner.
当然也可以下发部分SSB关联的其它SSB的信息，比如只下发SSB0-SSB3的bitmap；或者bitmap信息分多次下发，例如：一次下发一个SSB对应的bitmap，或者一次下发4个SSB对应的bitmap。Of course, it is also possible to send some SSB information related to other SSBs, such as only sending a bitmap of SSB0-SSB3; or sending the bitmap information multiple times, for example: sending a bitmap corresponding to one SSB at one time, or sending four Bitmap corresponding to SSB.
假设SSB的数目为N，则指示每个SSB的相邻SSB的bitmap需要的比特数为N或N-1，则N个SSB需要的总比特数N*N或N*(N-1)。因此，这种指示方式耗费的比特数较多，尤其是当N的数目较大的时候，但优点在于可以准确的指示出每个SSB的相邻SSB。Assuming that the number of SSBs is N, it indicates that the number of bits required by the bitmap of the adjacent SSBs of each SSB is N or N-1, and the total number of bits required by the N SSBs is N * N or N * (N-1). Therefore, this instruction method consumes a large number of bits, especially when the number of N is large, but the advantage is that it can accurately indicate the adjacent SSB of each SSB.
方法2，为了减少bitmap的比特数，可以对多个SSB进行分组指示。Method 2: In order to reduce the number of bits in the bitmap, multiple SSBs may be grouped and indicated.
例如：波束总数目为16个，参考图4左图，对应SSB0-SSB15。SSB0-SSB15被分为4组，每组4个SSB，每行作为一组，每组内的SSB重新编号，则分组后如图4右图所示。左图中的SSB0-SSB3对应右图的第一组(第一行)，在第一组内的编号分别为0-3；SSB4-SSB7对应第二组(第二行)，在第二组内的编号分别为0-3；SSB8-SSB11对应右图的第三组(第三行)，在第三组内的编号分别为0-3；SSB12-SSB15对应第四组(第四行)，在第四组内的编号分别为0-3。For example: the total number of beams is 16, referring to the left figure of Figure 4, corresponding to SSB0-SSB15. SSB0-SSB15 is divided into 4 groups, each group has 4 SSBs, each line is regarded as a group, and the SSBs in each group are renumbered. SSB0-SSB3 in the left picture corresponds to the first group (the first line) in the right picture, and the numbers in the first group are 0-3; SSB4-SSB7 corresponds to the second group (the second line), in the second group The numbers inside are 0-3; SSB8-SSB11 corresponds to the third group (third row) on the right, and the numbers in the third group are 0-3; SSB12-SSB15 corresponds to the fourth group (fourth row). The numbers in the fourth group are 0-3.
以SSB0为例，与SSB0相邻的SSB为SSB1，SSB6和SSB7，其中SSB1位于第一组(第一行)，SSB6和SSB7位于第二组(第二行)，第三组和第四组没有与SSB0相邻的SSB。Taking SSB0 as an example, the SSBs adjacent to SSB0 are SSB1, SSB6, and SSB7, where SSB1 is located in the first group (first row), SSB6 and SSB7 are located in the second group (second row), the third group and the fourth group There is no SSB adjacent to SSB0.
一种bitmap的指示方式为1100 0100 0011，其中1100为分组信息，指示每个组中是否含有与 SSB0相邻的SSB，1100表示第一组和第二组含有与SSB0相邻的SSB，第三组和第四组没有与SSB0相邻的SSB。0100和0011分别表示含有相邻SSB的组中具体的相邻SSB的位置，即含有相邻SSB的组中各个SSB是否为相邻SSB。0100表示第一组第二个SSB(即SSB1)为SSB0的相邻SSB，0011表示第二组第三个SSB和第四个SSB(即SSB6和SSB7)为SSB0的相邻SSB。这种指示方式相比上述方法1中的指示方式节省了4比特。A kind of bitmap indication method is 1100 01000011, where 1100 is grouping information indicating whether each group contains SSB0 adjacent to SSB0, 1100 indicates that the first and second groups contain SSB0 adjacent to SSB0, and the third Groups and the fourth group have no SSB adjacent to SSB0. 0100 and 0011 respectively indicate the positions of specific adjacent SSBs in the group containing adjacent SSBs, that is, whether each SSB in the group containing adjacent SSBs is an adjacent SSB. 0100 indicates that the second group of the first SSB (ie, SSB1) is a neighboring SSB of SSB0, and 0011 indicates that the third group of the second SSB and the fourth SSB (ie, SSB6 and SSB7) are adjacent SSB0 of the SSB0. This indication method saves 4 bits compared with the indication method in the above method 1.
另一种bitmap的指示方式为1100 0111，其中1100为分组信息，指示每个组中是否含有相邻SSB，1100表示第一组和第二组含有相邻SSB，第三组和第四组没有相邻SSB。Another bitmap indication method is 1100 0111, where 1100 is grouping information, indicating whether each group contains adjacent SSBs, 1100 indicates that the first and second groups contain adjacent SSBs, and the third and fourth groups do not have Adjacent SSB.
0111共同指示含有相邻SSB的组中具体的相邻SSB的位置。具体地，第一组和第二组中，后三个SSB为SSB0的相邻SSB，即第一组和第二组中SSB1，SSB2和SSB3(分组后编号)为SSB0的相邻SSB，其分组前的编号为SSB1，SSB2，SSB3，SSB5，SSB6，SSB7。其中，SSB2和SSB5实际并非SSB0的相邻SSB，但为了节省比特数，采用了共同指示的方式，将SSB2和SSB5也作为SSB0的相邻SSB。相比上面的指示方式(bitmap为1100 0100 0011)，将两组bitmap合并为一组，即将0100和0111合并为0111。这样指示方式指示相邻SSB的准确性降低，但相比上面一种指示方式，节省了4比特，相比方法1中的指示方式，则节省了8比特。0111 collectively indicates the position of a specific neighboring SSB in a group containing neighboring SSBs. Specifically, in the first and second groups, the last three SSBs are adjacent SSBs of SSB0, that is, in the first and second groups, SSB1, SSB2, and SSB3 (numbered after grouping) are adjacent SSBs of SSB0. The numbers before grouping are SSB1, SSB2, SSB3, SSB5, SSB6, SSB7. Among them, SSB2 and SSB5 are not actually adjacent SSB0 of SSB0, but in order to save the number of bits, a common indication method is adopted, and SSB2 and SSB5 are also used as adjacent SSB0 of SSB0. Compared with the above instruction (bitmap is 1100, 0100, and 0011), the two sets of bitmaps are combined into one group, that is, 0100 and 0111 are combined into 0111. In this way, the accuracy of the indication of the adjacent SSB is reduced, but compared with the above indication, 4 bits are saved, and compared with the indication in the method 1, 8 bits are saved.
SSB1-SSB15也可以分别采用上述与SSB0类似的bitmap指示方式，分别指示与各个SSB相邻的SSB。SSB1-SSB15 can also use the above-mentioned bitmap indication method similar to SSB0 to indicate the SSB adjacent to each SSB.
上述bitmap指示方式简称为分组指示，分组指示的下发方式与精确指示的下发方式类似，可以一次性下发或分多次下发，也可以只下发部分SSB的bitmap，可以参考精确指示的下发方式，这里不在赘述。The above bitmap instruction method is referred to as a group instruction for short. The group instruction is issued in a manner similar to that of the precise instruction. It can be issued at one time or multiple times, or only a part of the SSB bitmap. The delivery method is not repeated here.
以上以SSB的数目为16，分4组为例进行说明，SSB的数目有多种，不限于16，分组的方式也有多种；具体的分组方式可以是协议约定的，也可以网络设备和终端设备预定的，也可以是网络设备配置给终端设备的，实际应用中，可以根据实际传输的SSB的数目或者可能传输的SSB数目确定分组方式。In the above, the number of SSBs is 16 and it is divided into 4 groups as an example. There are many types of SSBs, not limited to 16, and there are many ways of grouping. The specific grouping method can be agreed by the protocol, or network equipment and terminals. The equipment reservation may also be configured by the network equipment to the terminal equipment. In practical applications, the grouping manner may be determined according to the number of SSBs actually transmitted or the number of SSBs that may be transmitted.
下表列举了一些具体的分组方式，L x M表示分为L小组，每一小组有M个SSB，L x M要大于或等于SSB的数目：The following table lists some specific grouping methods. LxxM indicates that it is divided into L groups. Each group has M SSBs. LxxM must be greater than or equal to the number of SSBs:

88 2x4或8x12x4 or 8x1
实际应用中不限于上述表中列举的分组方式，还可以有其它分组方式，只需要L x M大于或等于SSB的数目即可，SSB的数目为实际传输的SSB的数目或者可能传输的SSB数目，也可以为SSB的总数。In practice, it is not limited to the grouping methods listed in the above table, there may be other grouping methods, as long as Lx is greater than or equal to the number of SSBs, and the number of SSBs is the number of SSBs actually transmitted or the number of SSBs that may be transmitted , Can also be the total number of SSB.
当SSB数目较多，需要节省比特数时，适合使用上述bitmap分组指示。网络设备可以预先通知终端设备预定的SSB数量门限，当SSB数目高于该门限时，采用分组指示，当SSB数目低于该门限，则不分组，采用方式1的方式指示。上述门限也可以由协议规定。When the number of SSBs is large and the number of bits needs to be saved, the above bitmap grouping indication is suitable. The network device can notify the terminal device of a predetermined threshold of the number of SSBs in advance. When the number of SSBs is higher than the threshold, a grouping instruction is adopted. When the number of SSBs is lower than the threshold, the grouping is not performed, and the method is indicated in the first method. The above threshold may also be specified by agreement.
所述的门限值可以为4、5、6、7、8、9、10、12、14、15、16、18、20、21、24、25、28、30中的任意一个值，该值可以由网络设备配置给终端设备的，也可以是网络设备和终端设备预先设置，或协议规定的。当网络设备为终端设备配置的时候，可以使用***消息配置，该***消息可以为主信息块，最小剩余***信息，***信息块1，***信息块2，***信息块3，***信息块4，***信息块6，***信息块7，***信息块8，***信息块9，***信息块11，***信息块12，***信息块13，***信息块14，***信息块15，***信息块16，***信息块17，***信息块18，***信息块19，***信息块20，***信息块21，***信息块22，***信息块23，***信息块24，***信息块25，***信息块26中的任意一个***信息块。The threshold value may be any one of 4, 5, 6, 7, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 24, 25, 28, and 30. The value may be configured by the network device to the terminal device, or may be preset by the network device and the terminal device, or prescribed by a protocol. When the network device is configured for the terminal device, the system message configuration can be used. The system message can be the main information block, the minimum remaining system information, the system information block 1, the system information block 2, the system information block 3, and the system information block 4. System information block 6, system information block 7, system information block 8, system information block 9, system information block 11, system information block 12, system information block 13, system information block 14, system information block 15, system information block 16, System information block 17, system information block 18, system information block 19, system information block 20, system information block 21, system information block 22, system information block 23, system information block 24, system information block 25, system information block 26 Any of the system information blocks.
另外，上表中提到的分组方式也可以由网络设备预先配置给终端设备，或者由协议预先约定，具体可以参考上述门限的配置方式，不再赘述。In addition, the grouping methods mentioned in the above table can also be pre-configured by the network device to the terminal device, or pre-agreed by the protocol. For details, please refer to the above-mentioned threshold configuration method, which will not be described again.
上述SSB数量门限、分组方式都可以通过网络设备的配置信息下发。网络设备也可以配置该网络设备是否发送SSB之间的关联关系。The above SSB number thresholds and grouping methods can be delivered through the configuration information of the network device. The network device can also configure whether the network device sends the association relationship between the SSBs.
方法3，网络设备还可以使用SSB编号或标识，如SSB index(SSB索引号)，进行指示；即将每个SSB的关联SSB的编号下发给终端设备；关联SSB也称为相邻SSB。In method 3, the network device may also use an SSB number or identifier, such as an SSB index (SSB index number), to indicate; that is, the number of the associated SSB of each SSB is issued to the terminal device; the associated SSB is also called an adjacent SSB.
以SSB编号为SSB index为例，可以使用6bits进行指示与一个SSB关联的一个SSB index，一个SSB周围有3个相邻SSB，则需要6*3＝18bits进行指示。每个SSB关联的SSB都采用类似的方式进行指示，然后将各个SSB关联的SSB index下发即可。Taking the SSB number as the SSB index as an example, you can use 6 bits to indicate an SSB index associated with an SSB. If there are 3 adjacent SSBs around an SSB, you need 6 * 3 = 18 bits to indicate. The SSB associated with each SSB is instructed in a similar manner, and then the SSB index associated with each SSB can be sent.
SSB索引可以根据实际发送的SSB数量进行确定的。例如当实际发送的SSB数目为16的时候，索引编号可以从0～15，可以使用4bits的值指示一个SSB关联的一个SSB index。The SSB index can be determined according to the number of SSBs actually sent. For example, when the number of SSBs actually sent is 16, the index number can be from 0 to 15, and a 4bit value can be used to indicate an SSB index associated with an SSB.
同样，采用SSB索引方式进行指示，可以参考精确指示的方式，将每个SSB相关联的SSB index下发；也可以参考分组指示的方式，先将多个SSB进行分组，然后下发组信息，及组中相关联的SSB index；具体分组方式可以参考方法2，不再赘述。Similarly, the SSB index is used for instructions. You can refer to the precise instructions to send the SSB index associated with each SSB. You can also refer to the group instruction to group multiple SSBs first, and then send the group information. And the associated SSB index in the group; for specific grouping methods, refer to Method 2 and will not be described again.
SSB编号下发方式与方法1中的下发方式类似，可以一次性下发或分多次下发，也可以只下发 部分SSB的关联的SSB index，可以方法1中的下发方式，这里不在赘述。The SSB number delivery method is similar to the delivery method in Method 1. It can be delivered at one time or multiple times, or only the SSB index associated with some SSBs. The delivery method in Method 1 is available here. Not repeat them.
上述举例中，网络设备指示了每个SSB相关联的其它一个或多个SSB的信息，在另一个实施例中，网络设备还可以指示与每个SSB不关联的其它一个或多个SSB的信息，也就是指示与每个SSB不相邻或没有关联关系的其它一个或多个SSB的信息；例如：只需要将bitmap中的0变成1，1变成0即可，终端设备获知哪些SSB不相邻，剩余的便是相邻SSB。In the above example, the network device indicates information of one or more other SSBs associated with each SSB. In another embodiment, the network device may also indicate information of other one or more SSBs not associated with each SSB. That is, information indicating one or more other SSBs that are not adjacent or not associated with each SSB; for example, you only need to change 0 in the bitmap to 1, and 1 to 0, and the terminal device knows which SSBs Not adjacent, the rest are adjacent SSBs.
当然，上述各个举例中，也可以用1表示不相邻，0表示相邻。Of course, in each of the above examples, 1 can also be used to indicate non-adjacent, and 0 can be used to indicate adjacent.
网络设备还可以指示小区中的部分SSB不用进行测量。可以配置一个重复因子M1，网络设备可以指示M1个SSB中的SSB只测量一个SSB，或者指示M1个SSB可以当做一个SSB进行测量，或者M1个SSB是重复的；主要用来指示基站的重复波束不用进行RRM测量，终端设备接收后，便可以根据M1的值，减少SSB的测量。The network device may also instruct some SSBs in the cell not to perform measurements. A repetition factor M1 can be configured. The network device can instruct the SSB of M1 SSBs to measure only one SSB, or indicate that M1 SSBs can be measured as one SSB, or M1 SSBs are repeated; it is mainly used to indicate the repeating beam of the base station. No RRM measurement is required. After receiving, the terminal device can reduce the SSB measurement according to the value of M1.
在另一个实施例中，也可以使用CSI-RS来替代上述各个实施例中的SSB，因为一个波束对应一个或多个CSI-RS或一个或多个SSB，因此CSI-RS也可以指示波束或SSB。上述实施例中的指示信息携带多个CSI-RS之间的关联关系。In another embodiment, a CSI-RS may also be used instead of the SSB in each of the foregoing embodiments. Because one beam corresponds to one or more CSI-RS or one or more SSBs, the CSI-RS may also indicate the beam or SSB. The indication information in the foregoing embodiment carries an association relationship between multiple CSI-RSs.
多个CSI-RS之间的关联关系可以包括每个CSI-RS关联的CSI-RS，由于一个CSI-RS对应一个波束，因此指示信息可以指示每个波束的相邻波束，也就是每个CSI-RS的相邻CSI-RS，或称为每个CSI-RS具有关联关系的CSI-RS。该方法其它步骤与上述实施例类似，不再详述。The association relationship between multiple CSI-RSs can include the CSI-RS associated with each CSI-RS. Since one CSI-RS corresponds to one beam, the indication information can indicate the adjacent beam of each beam, that is, each CSI The adjacent CSI-RSs of the -RS, or CSI-RSs each having a correlation relationship with each other. The other steps of the method are similar to the above embodiments, and will not be described in detail.
另一个实施例中也可以用DMRS替换上述实施例中的SSB，如：寻呼PDCCH的DMRS，寻呼PDSCH的DMRS，PBCH的DMRS，SIB1的DMRS，SIB1的PDCCH的DMRS，SIB1的PDSCH的DMRS，公共搜索空间的DMRS，控制资源集合0的DMRS等，其它步骤与上述实施例类似，不再详述。In another embodiment, the SSB in the above embodiment may also be replaced with DMRS, such as: DMRS for paging PDCCH, DMRS for paging PDSCH, DMRS for PBCH, DMRS for SIB1, DMRS for PDCCH for SIB1, DMRS for PDSCH for SIB1 , The DMRS of the common search space, the DMRS of the control resource set 0, etc. The other steps are similar to the above embodiments, and will not be described in detail.
协议也可以定义几种固定的天线pattern，圆形天线pattern或者方形天线pattern。方形天线pattern可以为长方形天线pattern，也可以为正方型天线pattern。例如：4x4的正方形天线pattern，或者为圆形天线pattern。当为方形天线pattern的时候，可以为定义天线pattern的波束数目为X*Y，其中X表示行数，Y表示列数。终端设备可以根据X和Y推测出相邻波束，便可以获知各个SSB的相邻SSB。网络设备可以配置天线波束的行数和列数，并通知终端设备；也可以预先定义固定的天线pattern。The protocol can also define several fixed antenna patterns, circular antenna patterns or square antenna patterns. The square antenna pattern can be a rectangular antenna pattern or a square antenna pattern. For example: 4x4 square antenna pattern, or circular antenna pattern. When it is a square antenna pattern, the number of beams of the antenna pattern can be defined as X * Y, where X represents the number of rows and Y represents the number of columns. The terminal device can infer the neighboring beams according to X and Y, and then can know the neighboring SSB of each SSB. The network device can configure the number of rows and columns of the antenna beam and notify the terminal device; it can also define a fixed antenna pattern in advance.
本申请中网络设备下发给终端设备的各种信息，如，关联关系，SSB数量门限，分组方式，重复因子，天线pattern等，可以由网络设备配置，下发给终端设备，配置信息可以承载在物理广播信道(Physical Broadcast Channel，PBCH)、剩余最小***信息(Remaining minimum system information，RMSI)、***信息块(System Information Block，SIB)1、SIB2、SIB3，媒体接入控制控制元素(Media Access control-control element，MAC-CE)、下行控制信息(Down link control information，DCI)、无线资源控制(Radio Resource Control，RRC)以及***信息中的任意一项或多项；所述各种信息也可以由标准规定，或者网络设备和终端设备预先约定。Various information, such as association relationship, SSB number threshold, grouping mode, repetition factor, antenna pattern, etc., issued by the network equipment to the terminal equipment in this application can be configured by the network equipment and delivered to the terminal equipment, and the configuration information can be carried In Physical Broadcast Channel (PBCH), Remaining Minimum System Information (RMSI), System Information Block (SIB) 1, SIB2, SIB3, Media Access Control Element (Media Access Access) any one or more of control-control element (MAC-CE), downlink control information (DCI), radio resource control (RRC), and system information; the various kinds of information are also It can be stipulated by standards or agreed in advance by network equipment and terminal equipment.
