技术领域Technical Field
本申请涉及通信技术领域，尤其涉及通信系统中的波束成形技术。The present application relates to the field of communication technology, and in particular to beamforming technology in a communication system.
背景技术Background technique
波束成形技术是无线技术与数字信号处理技术的结合，其目的是实现定向传输信号或者接收定向信号。Beamforming technology is a combination of wireless technology and digital signal processing technology, and its purpose is to achieve directional transmission of signals or reception of directional signals.
由于采用波束成形技术的基站发射的波束具有指向性，使得只有处于发射波束方向上的用户设备才可以以较高的信噪比接收到基站发送的信号。因此，为了使得基站信号能够全面覆盖该基站的所有小区，基站需要不断地进行波束切换，即通过改变波束发射方向来形成不同方向的波束。波束成形技术包括数字波束成形和模拟波束成形两大类，模拟波束成形具有较低的复杂度和成本。然而模拟波束每次切换均需要占用一定的时长，导致波束切换的时间开销过大。Since the beams transmitted by base stations using beamforming technology are directional, only user equipment in the direction of the transmitted beam can receive the signal sent by the base station with a higher signal-to-noise ratio. Therefore, in order for the base station signal to fully cover all cells of the base station, the base station needs to continuously switch beams, that is, to form beams in different directions by changing the direction of beam transmission. Beamforming technology includes two categories: digital beamforming and analog beamforming. Analog beamforming has lower complexity and cost. However, each switching of analog beams takes a certain amount of time, resulting in excessive time overhead for beam switching.
发明内容Summary of the invention
本申请提供了一种波束处理方法和基站，以降低波束切换的开销。The present application provides a beam processing method and a base station to reduce the overhead of beam switching.
为实现上述目的，本申请提供如下技术方案：To achieve the above objectives, this application provides the following technical solutions:
一方面，本申请提供了一种波束处理方法，该方法包括：基站获取待以波束形式发送的多个连续符号；如果这多个连续符号中包括用于进行上下行之间转换的转换间隔时，则向小区内的用户设备发送消息，该消息用于将基站在该转换间隔处进行波束切换的信息通知给该用户设备。On the one hand, the present application provides a beam processing method, which includes: a base station obtains multiple consecutive symbols to be sent in the form of a beam; if these multiple consecutive symbols include a switching interval for switching between uplink and downlink, a message is sent to a user equipment in the cell, and the message is used to notify the user equipment of the information that the base station performs beam switching at the switching interval.
从以上方面可以看出，如果待以模拟波束形式发送的多个连续符号中包括用于进行上下行切换的转换间隔，则将该转换间隔所占用的时间作为进行波束切换的时间，并通知给用户设备，实现了复用基站进行上下行转换的时间来进行波束切换，从而无需在该转换间隔符号处单独预留波束切换时间，有利于减少波束切换的时间开销。From the above aspects, it can be seen that if the multiple consecutive symbols to be sent in the form of analog beams include a transition interval for uplink and downlink switching, the time occupied by the transition interval is used as the time for beam switching and notified to the user equipment, thereby realizing the time for multiplexing the base station to perform uplink and downlink conversion to perform beam switching, thereby eliminating the need to reserve beam switching time separately at the transition interval symbol, which is beneficial to reducing the time overhead of beam switching.
在一个可能的设计中，基站所述向小区内的用户设备发送消息之后，依次发送所述多个连续符号，且如果当前待发送的符号为所述转换间隔时，则在转换间隔所对应的时长内进行波束切换。基站在确定当前待发送的信号为转换间隔时，在该转换间隔所对应的时长进行波束切换，复用了转换间隔所对应的时长作为波束切换的时长，可以减少波束切换时间。In one possible design, after the base station sends a message to a user equipment in the cell, it sends the multiple consecutive symbols in sequence, and if the symbol to be currently sent is the transition interval, the beam switching is performed within the duration corresponding to the transition interval. When the base station determines that the signal to be currently sent is a transition interval, the beam switching is performed within the duration corresponding to the transition interval, and the duration corresponding to the transition interval is reused as the duration of the beam switching, which can reduce the beam switching time.
在一个可能的设计中，所述转换间隔包括：用于上行到下行转换的时间间隔；或者，用于下行到上行转换的保护间隔。In one possible design, the switching interval includes: a time interval for uplink to downlink switching; or a protection interval for downlink to uplink switching.
在一个可能的设计中，基站在获取待以模拟波束形式发送的多个连续符号之后，确定该多个连续符号中的目标符号，目标符号所对应的时长为预设的用于进行波束切换的时长；其中，通过如下方式，在该多个连续符号中设置该目标符号：基于多个连续符号的前后顺序，并按照预设的符号间隔数量，依次确定该多个连续符号所对应的符号位中，待预留波束切换时间的待定符号位；如果该多个连续符号中存在转换间隔，则从待定符号位中确定不与转换间隔相邻的目标符号位，并将目标符号位设置为该目标符号，从而无需在与该转换间隔相邻的待定位置点预留波束切换时间，从而可以减少了预留的波束切换时间；这样，向UE发送的消息还可以用于将基站在该目标符号处进行波束切换的信息通知给该用户设备。In one possible design, after obtaining multiple consecutive symbols to be sent in the form of an analog beam, the base station determines a target symbol among the multiple consecutive symbols, and the duration corresponding to the target symbol is a preset duration for beam switching; wherein the target symbol is set among the multiple consecutive symbols in the following manner: based on the front-to-back order of the multiple consecutive symbols, and according to a preset number of symbol intervals, the pending symbol bits for the reserved beam switching time in the symbol bits corresponding to the multiple consecutive symbols are determined in sequence; if there is a transition interval among the multiple consecutive symbols, the target symbol bit that is not adjacent to the transition interval is determined from the pending symbol bits, and the target symbol bit is set to the target symbol, thereby eliminating the need to reserve the beam switching time at the pending position point adjacent to the transition interval, thereby reducing the reserved beam switching time; in this way, the message sent to the UE can also be used to notify the user equipment of the information that the base station performs beam switching at the target symbol.
在一种可能的设计中，可以通过物理下行控制信道或者高层无线资源控制向该小区内的用户传输该消息。In one possible design, the message may be transmitted to users in the cell via a physical downlink control channel or high-level radio resource control.
在一种可能的设计中，该消息用于将在所述转换间隔之前最近一次发射波束所采用的标识信号，以及在所述转换间隔符号之后最近一次发射波束所采用的该标识信号，通知给所述用户设备；其中，该标识信号包括：公共参考信号、状态信息参考信号或者发现信号中的一项或多于一项。In one possible design, the message is used to notify the user equipment of an identification signal used by the most recent transmitted beam before the transition interval and an identification signal used by the most recent transmitted beam after the transition interval symbol; wherein the identification signal includes: one or more of a common reference signal, a status information reference signal or a discovery signal.
另一方面，本发明实施例提供了一种基站，该基站具有实现上述方法实际中基站行为的功能。所述功能可以通过硬件实现，也可以通过硬件执行相应的软件实现。所述硬件或软件包括一个或多个与上述功能相对应的模块。On the other hand, an embodiment of the present invention provides a base station having the function of implementing the base station behavior in the above method. The function can be implemented by hardware or by hardware executing corresponding software. The hardware or software includes one or more modules corresponding to the above functions.
在一种可能的设计中，该基站包括处理器和发射器，该处理器被配置为支持基站执行上述方法中相应的功能；发射器用于支持基站与UE之间的通信，向UE发送上述方法中所涉及的信息或者指令。所述基站还可以包括存储器，所述存储器用于与处理器耦合，其保存基站必要的程序指令和数据。In one possible design, the base station includes a processor and a transmitter, the processor is configured to support the base station to perform corresponding functions in the above method; the transmitter is used to support communication between the base station and the UE, and send information or instructions involved in the above method to the UE. The base station may also include a memory, which is coupled to the processor and stores program instructions and data necessary for the base station.
此外，以上基站也可以为其他无线网络设备，UE也可以为其他无线网络设备，比如，基站上位为第一无线网络设备，UE上位为第二无线网络设备，第一无线网络设备和第二无线网络设备可以执行以上所提供的方法，第一无线网络设备可以包括处理器和收发器，该处理器被配置为支持第一无线网络设备执行上述方法中相应的功能；发射器用于支持第一无线网络设备与第二无线网络设备之间的通信，向第二无线网络设备发送上述方法中所涉及的信息或者指令。所述基站还可以包括存储器，所述存储器用于与处理器耦合，其保存第一无线网络设备必要的程序指令和数据。In addition, the above base station can also be other wireless network devices, and the UE can also be other wireless network devices.

The first wireless network device and the second wireless network device can perform the method provided above. The first wireless network device may include a processor and a transceiver. The processor is configured to support the first wireless network device to perform the corresponding functions in the above method; the transmitter is used to support the communication between the first wireless network device and the second wireless network device, and send the information or instructions involved in the above method to the second wireless network device. The base station may also include a memory, which is used to couple with the processor and store the necessary program instructions and data for the first wireless network device.

Figure 2a is a schematic diagram of the structure of the base station in the communication system shown in Figure 1. As shown in Figure 2a, the base station may include an antenna array, a duplexer, a transmitter (Transmitter, referred to as "TX"), a receiver (Receiver, referred to as "RX") (TX and RX may be collectively referred to as transceivers TRX), and a baseband processing part. Among them, the duplexer is used to implement the antenna array, which can be used for both sending and receiving signals. TX is used to realize the conversion between RF signals and baseband signals. Usually TX may include a power amplifier (Power Amplifier, referred to as "PA"), a digital to analog converter (Digital to Analog Converter, referred to as "DAC"), and a frequency converter. Usually RX may include a low-noise amplifier (Low-Noise Amplifier, referred to as "LNA"), an analog to digital converter (Analog to Digital Converter, referred to as "ADC"), and a frequency converter. The baseband processing part is used to implement the processing of the transmitted or received signals, such as layer mapping, precoding, modulation/demodulation, coding/compilation, etc., and to process the physical control channel, physical data channel, physical broadcast channel, reference signal, etc. Further, the base station may also include a control part for multi-user scheduling and resource allocation, pilot scheduling, user physical layer parameter configuration, etc.
如图2b所示，图2b为图1所示的通信系统中的用户设备的结构示意图。用户设备可以包括天线、双工器、TX和RX(TX和RX可以统称为收发机TRX)，以及基带处理部分。如图2b所示，用户设备具有多天线(即天线阵列)。应理解，用户设备也可以具有单天线。其中，双工器使天线阵列实现既可用于发送信号，又可用于接收信号。TX用于实现射频信号和基带信号之间的转换，通常TX可以包括PA、DAC和变频器，通常RX可以包括LNA、ADC和变频器。基带处理部分用于实现所发送或接收的信号的处理，比如，层映射、预编码、调制/解调、编码/译码等，并且对于物理控制信道、物理数据信道、物理广播信道、参考信号等进行分别的处理。进一步的，用户设备还可以包括控制部分，用于请求上行物理资源、计算下行信道对应的信道状态信息(Channel State Information，简称为“CSI”)、判断下行数据包是否接收成功等。As shown in FIG. 2b, FIG. 2b is a schematic diagram of the structure of the user equipment in the communication system shown in FIG. 1. The user equipment may include an antenna, a duplexer, TX and RX (TX and RX may be collectively referred to as a transceiver TRX), and a baseband processing part. As shown in FIG. 2b, the user equipment has multiple antennas (i.e., an antenna array). It should be understood that the user equipment may also have a single antenna. Among them, the duplexer enables the antenna array to be used for both sending and receiving signals. TX is used to realize the conversion between RF signals and baseband signals. Usually TX may include PA, DAC and frequency converter, and usually RX may include LNA, ADC and frequency converter. The baseband processing part is used to realize the processing of the transmitted or received signals, such as layer mapping, precoding, modulation/demodulation, encoding/decoding, etc., and to process the physical control channel, physical data channel, physical broadcast channel, reference signal, etc. separately. Further, the user equipment may also include a control part for requesting uplink physical resources, calculating the channel state information (Channel State Information, referred to as "CSI") corresponding to the downlink channel, and judging whether the downlink data packet is received successfully.
基站侧和/或用户侧通过配置天线阵列，利用波束成形技术增强覆盖。所述天线阵列的波束成形包括天线阵列形成的模拟波束和混合波束。进一步的，请参见图3，图3为混合波束成形示意图。如图3所示，基带处理部分完成一般的基带数字信号处理，包括CRC校验、编码、调制、加扰、数字波束成形等；基带处理后的数字信号送入发射射频(RadioFrequency，简称为“RF”)链路(图中仅画出两个射频链路，在实际应用中，可以包含一个至多个射频链路)，发射射频链路完成上采样、发射成形滤波、削波、模拟数字转换等功能；射频处理后的模拟信号被送到多个功放、移相器、天线单元中，用来进行模拟波束成形；基带处理部分通过控制射频移相器的相位，即可实现具有一定指向性的信号的发送。所述指向性指的是电磁波能量的传播指向性，这种由多个模拟移相器合成的具有指向性的信号称为模拟波束。射频移相器一般是通过延迟线或者PIN二极管实现的，在相位调整时需要消耗一定时间，因此在进行通信协议设计时，需要考虑波束切换时间的影响。The base station side and/or the user side configures the antenna array and uses beamforming technology to enhance coverage. The beamforming of the antenna array includes analog beams and hybrid beams formed by the antenna array. Further, please refer to Figure 3, which is a schematic diagram of hybrid beamforming. As shown in Figure 3, the baseband processing part completes general baseband digital signal processing, including CRC check, coding, modulation, scrambling, digital beamforming, etc.; the digital signal after baseband processing is sent to the transmitting radio frequency (Radio Frequency, referred to as "RF") link (only two RF links are drawn in the figure, in actual applications, it can include one to multiple RF links), and the transmitting RF link completes upsampling, transmission shaping filtering, clipping, analog-to-digital conversion and other functions; the analog signal after RF processing is sent to multiple power amplifiers, phase shifters, and antenna units for analog beamforming; the baseband processing part can realize the transmission of signals with certain directivity by controlling the phase of the RF phase shifter. The directivity refers to the propagation directivity of electromagnetic wave energy. This directional signal synthesized by multiple analog phase shifters is called an analog beam. RF phase shifters are generally implemented through delay lines or PIN diodes, which take a certain amount of time to adjust the phase. Therefore, when designing communication protocols, the impact of beam switching time needs to be considered.
由于每次波束切换均需要占用一定时长，在以模拟波束形式发送多个连续符号的过程中，每间隔预设数量个符号就需要预留一次波束切换的切换时间，从而使得波束切换占用较多时长。Since each beam switching takes a certain amount of time, in the process of sending multiple consecutive symbols in the form of analog beams, it is necessary to reserve a beam switching time every preset number of symbols, so that the beam switching takes a long time.
下面将基于上面所述的本申请涉及的共性方面，对本申请实施例进一步详细说明。The embodiments of the present application will be further described in detail below based on the common aspects of the present application described above.
本申请实施例提供了一种波束处理方法，和基于该方法的基站。基站获取待以波束形式发送的多个符号，如果这多个符号中存在用于进行上下行之间转换的转换间隔时，则向UE发送消息，该消息用于将基站在该转换间隔处进行波束切换的信息，通知给UE。The embodiment of the present application provides a beam processing method and a base station based on the method. The base station obtains multiple symbols to be sent in the form of a beam, and if there is a switching interval for switching between uplink and downlink in the multiple symbols, a message is sent to the UE, and the message is used to notify the UE of information that the base station performs beam switching at the switching interval.
如果待发送的多个连续符号中包括用于进行上下行之间转换的转换间隔，则由于需要在该转换间隔处进行下行到上行或者上行到下行的转换，而设置该转换间隔所占用的时长较长，且该转换间隔所占用的时长大于波束切换所需的时长。这样，在基站在转换间隔处进行下行到上行或者上行到下行转换的同时，进行波束切换，则无需单独耗费波束切换时间，从而复用该转换间隔所占用的时长来进行波束切换，有利于在增加波束切换次数的前提下，减少波束切换的时间开销。If a switching interval for switching between uplink and downlink is included in the multiple consecutive symbols to be sent, the duration occupied by the switching interval is set to be longer because it is necessary to perform a downlink-to-uplink or uplink-to-downlink conversion at the switching interval, and the duration occupied by the switching interval is greater than the duration required for beam switching. In this way, when the base station performs a downlink-to-uplink or uplink-to-downlink conversion at the switching interval, it performs beam switching without consuming beam switching time separately, thereby reusing the duration occupied by the switching interval to perform beam switching, which is beneficial to reducing the time overhead of beam switching while increasing the number of beam switching.
下面结合附图4，对本申请的实施例提供的方案进行说明。The solution provided by the embodiment of the present application is described below in conjunction with FIG4 .
如图4所示，本申请实施例提供的波束处理方法包括：As shown in FIG4 , the beam processing method provided in the embodiment of the present application includes:
401，获取待以模拟波束形式发送的多个连续符号。401. Obtain a plurality of continuous symbols to be sent in the form of an analog beam.
其中，获取的多个连续符号可以与现有模拟波束或混合模拟波束发射中的符号相同，如该多个连续符号可以为一个子帧，在此不再赘述。Among them, the multiple continuous symbols obtained can be the same as the symbols in the existing analog beam or hybrid analog beam transmission. For example, the multiple continuous symbols can be a subframe, which will not be repeated here.
402，如果该多个连续符号中包括至少一个用于进行上下行之间转换的转换间隔时，则向小区内的用户设备发送消息。402: If the multiple consecutive symbols include at least one switching interval for switching between uplink and downlink, send a message to user equipment in the cell.
其中，该消息用于将基站在该转换间隔处进行波束切换的信息，通知给UE。其中，本申请实施例中的UE为处于该基站覆盖的小区内的UE。The message is used to notify the UE of information that the base station performs beam switching at the switching interval. The UE in the embodiment of the present application is a UE in a cell covered by the base station.
如果该多个连续符号中包括转换间隔，则说明由该多个连续符号组成的帧或子帧中，同时包括下行符号和上行符号，基站需要在该转换间隔对应的时间间隔内进行上下行之间的转换。其中，上下行之间的转换可以为上行到下行的转换或者是下行到上行之间的转换。If the multiple continuous symbols include a conversion interval, it means that the frame or subframe composed of the multiple continuous symbols includes both downlink symbols and uplink symbols, and the base station needs to perform the conversion between uplink and downlink within the time interval corresponding to the conversion interval. The conversion between uplink and downlink can be a conversion from uplink to downlink or a conversion from downlink to uplink.
在本申请实施例中，基站将进行上下行之间转换的时长作为预留的波束切换时间，即，将该转换间隔所对应的时间确定为进行波束切换的时间。In an embodiment of the present application, the base station uses the duration of switching between uplink and downlink as the reserved beam switching time, that is, the time corresponding to the switching interval is determined as the time for beam switching.
本申请实施例中，如果待以模拟波束形式发送的多个连续符号中包括用于进行上下行之间转换的转换间隔，则将转换间隔所对应的时间作为进行波束切换的时间，并通知给UE，实现了复用基站进行上下行之间转换的时间来进行波束切换，从而无需在该转换间隔处单独预留波束切换时间，有利于减少波束切换时间。In an embodiment of the present application, if multiple consecutive symbols to be sent in the form of an analog beam include a transition interval for switching between uplink and downlink, the time corresponding to the transition interval is used as the time for beam switching and notified to the UE, thereby realizing the beam switching by multiplexing the time for the base station to switch between uplink and downlink, thereby eliminating the need to reserve a separate beam switching time at the transition interval, which is beneficial to reducing the beam switching time.
同时，由于复用该转换间隔的时间进行波束切换不会增加波束开销，则当该多个连续符号中出现用于进行上下行之间转换的转换间隔就进行波束切换，也有利于在不增加波束切换开销的前提下，增加波束切换次数，从而可以减少波束切换周期过大而导致的UE跟踪慢、接入延迟大等UE的信号接收异常。At the same time, since multiplexing the conversion interval time for beam switching will not increase the beam overhead, beam switching is performed when the conversion interval for switching between uplink and downlink appears in the multiple consecutive symbols. This is also beneficial to increase the number of beam switching without increasing the beam switching overhead, thereby reducing UE signal reception abnormalities such as slow UE tracking and large access delay caused by excessive beam switching period.
可以理解的是，在向小区内的UE发送消息之后，基站可以发送该多个连续的符号，且当待发送符号为用于进行上下行之间转换的转换间隔时，则基站在该转换间隔所对应的时长内进行上下行之间的转换；同时，基站在该转换间隔所对应的时长内进行波束切换，即通过改变移相器的相位，改变波束输出方向。It can be understood that after sending a message to the UE in the cell, the base station can send the multiple consecutive symbols, and when the symbol to be sent is a transition interval for switching between uplink and downlink, the base station performs the switch between uplink and downlink within the time length corresponding to the transition interval; at the same time, the base station performs beam switching within the time length corresponding to the transition interval, that is, changes the beam output direction by changing the phase of the phase shifter.
可以理解的是，用于进行上下行之间转换的转换间隔可以理解为该多个连续符号中包括的用于进行上下行转换的时长。而该转换间隔具体可以分为两种：一种是用于上行到下行转换的时间间隔。另一种是用于下行到上行转换的时间间隔，其中，用于下行到上行转换的时间间隔也可以称为保护间隔(GP，guard period)。It can be understood that the conversion interval for switching between uplink and downlink can be understood as the duration for uplink and downlink switching included in the multiple consecutive symbols. The conversion interval can be specifically divided into two types: one is the time interval for uplink to downlink conversion. The other is the time interval for downlink to uplink conversion, where the time interval for downlink to uplink conversion can also be called a guard period (GP).
在实际应用中，该连续多个符号中有可能仅包括用于上行到下行转换的时间间隔，或者是仅包括保护间隔；当然，也可能存在该连续的多个符号中同时包括多个转换间隔的情况，在该种情况下，这多个连续符号会交替出现用于下行到上行转换的时间间隔以及上行到下行转换的时间间隔。然而基站在上行通信过程中并不会进行波束发射，因此，如果在任意相邻的下行转上行时间间隔和上行转下行时间间隔这两个转换间隔处均进行波束切换，则由于在这两个转换间隔处所进行的两次波束切换中，只有上行符号而不存在基站的波束发射，而使得这两次波束切换中有一次波束切换是没有意义的。In practical applications, the multiple continuous symbols may only include time intervals for uplink to downlink conversion, or only include protection intervals; of course, there may also be a situation where the multiple continuous symbols include multiple conversion intervals at the same time. In this case, the multiple continuous symbols will alternately appear as time intervals for downlink to uplink conversion and time intervals for uplink to downlink conversion. However, the base station does not perform beam transmission during uplink communication. Therefore, if beam switching is performed at any adjacent downlink to uplink time interval and uplink to downlink time interval, then because there are only uplink symbols and no beam transmission of the base station in the two beam switches performed at the two conversion intervals, one of the two beam switches is meaningless.
为了减少无意义的波束切换，如果该多个连续符号中包括多个用于进行上下行之间转换的转换间隔时，则可以仅仅选取一种类型的转换间隔的时长复用为波束切换的时长。如，可以将这多个连续符号中的保护间隔符号所对应的时长作为进行波束切换的时长。In order to reduce meaningless beam switching, if the multiple consecutive symbols include multiple switching intervals for switching between uplink and downlink, the duration of only one type of switching interval can be selected and multiplexed as the duration of beam switching. For example, the duration corresponding to the guard interval symbol in the multiple consecutive symbols can be used as the duration of beam switching.
考虑到基站进行了上行到下行的转换后，就会波束发送，因此，可以将用于上行到下行转换的时间间隔所对应的时长作为进行波束切换的时长，即，如果该多个连续符号中包括用于上行到下行转换的转换间隔时，则向UE发送消息，该消息用于将基站在该用于上行到下行转换的转换间隔处进行波束切换的信息通知给UE。Taking into account that the base station will send beams after performing the uplink-to-downlink conversion, the duration corresponding to the time interval for the uplink-to-downlink conversion can be used as the duration for beam switching, that is, if the multiple consecutive symbols include a conversion interval for uplink-to-downlink conversion, a message is sent to the UE, and the message is used to notify the UE that the base station performs beam switching at the conversion interval for uplink-to-downlink conversion.
需要说明的是，在实际应用中，当获取到的多个连续符号中所包含的符号数量较多时，在待发送的多个连续符号中，除了会包括用于上下行转换的转换间隔外，还可能会包括：预设的目标符号，该目标符号所对应的时长为预设的用于进行波束切换的时长。It should be noted that in actual applications, when the number of symbols contained in the multiple consecutive symbols obtained is large, the multiple consecutive symbols to be sent, in addition to the conversion interval for uplink and downlink conversion, may also include: a preset target symbol, and the duration corresponding to the target symbol is the preset duration for beam switching.
则，在获取到该多个连续符号之后，可以确定出该多个连续符号中的目标符号。相应的，基站向UE发送的消息除了用于将基站在该转换间隔处进行波束切换的信息，通知给UE之外，还可以用于将基站在目标符号所对应的时长内进行波束切换的信息通知给该UE。Then, after acquiring the multiple consecutive symbols, the target symbol in the multiple consecutive symbols can be determined. Accordingly, the message sent by the base station to the UE can be used to notify the UE of the information that the base station performs beam switching at the transition interval, and can also be used to notify the UE of the information that the base station performs beam switching within the duration corresponding to the target symbol.
可以理解的是，该多个连续符号中所包含的目标符号的具体位置以及具体数量可以由生成该多个连续符号的基站根据需要设置。而在该多个连续符号所对应的符号位中放置一个或多个目标符号的实现方式可以有多种。It is understandable that the specific position and specific number of the target symbols included in the multiple continuous symbols can be set by the base station generating the multiple continuous symbols as needed. There are multiple ways to place one or more target symbols in the symbol bits corresponding to the multiple continuous symbols.
可选的，可以参见图5，其示出了在多个连续符号对应的符号位中设置目标符号的一种实现方式的流程示意图，该种方式的实现过程可以包括：Optionally, see FIG. 5 , which shows a flow chart of an implementation method of setting a target symbol in a symbol bit corresponding to a plurality of consecutive symbols. The implementation process of this method may include:
501，基于该多个连续符号的前后顺序，并按照预设的符号间隔数量，依次确定该多个连续符号所对应的符号位中，待预留波束切换时间的待定符号位。501. Based on the sequence of the multiple consecutive symbols and according to a preset number of symbol intervals, determine in sequence the pending symbol bits for the reserved beam switching time among the symbol bits corresponding to the multiple consecutive symbols.
502，如果这多个连续符号中存在至少一个转换间隔，则从该待定符号位中确定不与该转换间隔相邻的目标符号位，并在该目标符号位设置该目标符号。502 , if there is at least one transition interval among the multiple consecutive symbols, determine a target symbol bit that is not adjacent to the transition interval from the pending symbol bits, and set the target symbol at the target symbol bit.
其中，该目标符号所对应的时长为进行波束切换的时长。The duration corresponding to the target symbol is the duration for beam switching.
可以理解的是，当待定符号位与转换间隔相邻时，可以直接将该转换间隔所对应的时长作为波束切换所需的时长，从而无需在该待定符号位处再单独预留波束切换时间，因此，与该转换间隔相邻的待定符号位无需作为进行波束切换的位置点，而只需将不与转换间隔相邻的待定符号位以及该转换间隔作为待进行波束切换的位置点。It can be understood that when the pending symbol bit is adjacent to the transition interval, the duration corresponding to the transition interval can be directly used as the duration required for beam switching, so there is no need to reserve a separate beam switching time at the pending symbol bit. Therefore, the pending symbol bit adjacent to the transition interval does not need to be used as the position point for beam switching, but only the pending symbol bit not adjacent to the transition interval and the transition interval need to be used as the position points for beam switching.
其中，将目标符号位确定为待进行波束切换的位置点后，目标符号位所对应的时长即为预留出的进行波束切换时长。Among them, after the target symbol bit is determined as the position point for beam switching, the duration corresponding to the target symbol bit is the reserved beam switching duration.
可选的，在该目标符号位设置该目标符号可以理解为在目标符号位放置设定时长的空白时长，比如空白符号，其中，该设定时长可以根据波束切换所需的时长来进行设定。在目标符号位设置空白符号后，后续进行波束切换时，便可以在该空白符号所对应的设定时长内进行波束切换。Optionally, setting the target symbol at the target symbol position can be understood as placing a blank time length of a set time length at the target symbol position, such as a blank symbol, wherein the set time length can be set according to the time length required for beam switching. After the blank symbol is set at the target symbol position, when beam switching is performed subsequently, beam switching can be performed within the set time length corresponding to the blank symbol.
当然，也可以通过其他方式标识出在该目标符号位预留了波束切换时间，以便在发送该多个连续符号的过程中，当待发送符号为该目标符号时，在该目标符号所对应的时长内不进行符号发送，而仅在该目标符号所对应的时长内进行波束切换。Of course, it is also possible to mark in other ways that the beam switching time is reserved for the target symbol position, so that in the process of sending the multiple consecutive symbols, when the symbol to be sent is the target symbol, the symbol is not sent within the time length corresponding to the target symbol, and the beam switching is only performed within the time length corresponding to the target symbol.
如果按照预设的符号间隔，从该多个连续符号所对应的符号位中确定出的待预留波束切换时间的待定符号位，与该多个连续符号中的转换间隔相邻，则可以直接将转换间隔所对应的时间作为该待定位置点所需预留的波束切换时间，从而减少了预留的波束切换时间，降低了波束切换的时间开销。If the pending symbol bit of the reserved beam switching time determined from the symbol bits corresponding to the multiple consecutive symbols according to the preset symbol interval is adjacent to the transition interval in the multiple consecutive symbols, then the time corresponding to the transition interval can be directly used as the beam switching time required to be reserved for the pending position point, thereby reducing the reserved beam switching time and reducing the time overhead of beam switching.
需要说明的是，在本申请实施例中该转换间隔可以为用于进行上下行之间转换的所有转换间隔，也可以仅仅是用于下行到上行转换的转换间隔；或者是仅仅为GP。It should be noted that, in the embodiment of the present application, the conversion interval may be all conversion intervals used for conversion between uplink and downlink, or may be only the conversion interval used for downlink to uplink conversion; or may be only the GP.
在以上任意一个实施例中，在将在该目标符号处和转换间隔处进行波束切换的信息通知给UE之后，基站可以以模拟波束的形式发送给多个连续符号。具体的，依次发送该多个连续符号；在发送该多个连续符号的过程中，如果检测到转换间隔符号或者预设的目标符号，则控制移相器的相位改变，以实现波束方向切换。In any of the above embodiments, after notifying the UE of information about beam switching at the target symbol and the transition interval, the base station may send multiple continuous symbols in the form of an analog beam. Specifically, the multiple continuous symbols are sent in sequence; during the process of sending the multiple continuous symbols, if a transition interval symbol or a preset target symbol is detected, the phase of the phase shifter is controlled to change to achieve beam direction switching.
可以理解的是，在以上任意一个实施例中，基站可以通过多种方式将在多个连续符号中的转换间隔处进行的波束切换的信息通知给UE。可选的，基站可以通过隐式或者显式，动态或者半动态的向UE发送消息。该消息可以用于将该转换间隔前后的模拟波束信息发送给UE，该模拟波束信息包括用于区分不同模拟波束的模拟波束标识。当然，基站将目标符号处进行波束切换的信息通知给UE的方式也可以是通过隐式或者显示，动态或半动态的向UE发送消息。It can be understood that in any of the above embodiments, the base station can notify the UE of the information of the beam switching performed at the transition interval in multiple consecutive symbols in a variety of ways. Optionally, the base station can send a message to the UE implicitly or explicitly, dynamically or semi-dynamically. The message can be used to send the simulated beam information before and after the transition interval to the UE, and the simulated beam information includes a simulated beam identifier for distinguishing different simulated beams. Of course, the way for the base station to notify the UE of the information of the beam switching at the target symbol can also be by implicitly or explicitly, dynamically or semi-dynamically sending a message to the UE.
模拟波束信息可以通过指定的标识信号承载。如，该模拟波束信息可以通过小区级参考信号(CRS，cell-specific reference signal)(也可称为公共参考信号)承载。基站可以将发射该多个连续符号段中不同符号段所用的模拟波束对应的CRS，发送给小区内的用户设备。相应的，当不同符号段所对应的模拟波束用波束标识进行区分时，则不同模拟波束标识对应着不同的公共参考信号，也即公共参考信号与模拟波束标识一一对应。The analog beam information can be carried by a designated identification signal. For example, the analog beam information can be carried by a cell-level reference signal (CRS, cell-specific reference signal) (also called a common reference signal). The base station can send the CRS corresponding to the analog beams used to transmit different symbol segments in the multiple consecutive symbol segments to the user equipment in the cell. Correspondingly, when the analog beams corresponding to different symbol segments are distinguished by beam identifiers, different analog beam identifiers correspond to different common reference signals, that is, the common reference signal corresponds one-to-one to the analog beam identifier.
具体的，当消息用于将基站在该转换间隔处进行波束切换的信息，通知给该UE时，则可以将在该转换间隔之前最近一次发射波束所采用的CRS，通知给UE，当然，还可以将在该转换间隔之后最近一次发射波束所采用的CRS，通知给UE。也就是说，将该多个连续符号中，被该转换间隔划分出的多个符号段所各自对应的CRS，通知给UE。其中，该多个符号段采用不同发射方向的波束进行发射。Specifically, when the message is used to notify the UE of the information that the base station performs beam switching at the transition interval, the CRS used by the most recent beam transmitted before the transition interval can be notified to the UE. Of course, the CRS used by the most recent beam transmitted after the transition interval can also be notified to the UE. In other words, the CRS corresponding to each of the multiple symbol segments divided by the transition interval in the multiple continuous symbols is notified to the UE. The multiple symbol segments are transmitted using beams in different transmission directions.
当消息用于将基站在该目标符号处和该转换间隔处进行波束切换的信息，通知给该UE时，则可以该消息中可以携带有该多个连续符号中的多个目标符号段所对应公共参考信号。其中，该目标符号段为该多个连续符号中，被预设的目标符号和该转换间隔切分出的多个符号段。When the message is used to notify the UE of information that the base station performs beam switching at the target symbol and the transition interval, the message may carry a common reference signal corresponding to multiple target symbol segments in the multiple consecutive symbols. The target symbol segment is a plurality of symbol segments in the multiple consecutive symbols that are divided by the preset target symbol and the transition interval.
当消息用于将基站在该目标符号处进行波束切换的信息，通知给该UE时，则可以将目标符号处之前最近一次发射波束所采用的CRS，通知给UE；和/或，将在该目标符号处之后最近一次发射波束所采用的CRS，通知给UE。When the message is used to notify the UE of the information that the base station performs beam switching at the target symbol, the CRS used for the most recent transmitted beam before the target symbol can be notified to the UE; and/or the CRS used for the most recent transmitted beam after the target symbol can be notified to the UE.
当然，除了通过向UE发送CRS外，基站还可以向UE发送其他标识信号，如基站可以向UE发送信道状态信息参考信号(CSI-RS，Channel-State Information–ReferenceSignal)，或者向UE发送发现信号(Discovery Reference Signal)中的一项或多于一项。其中，该发现信号可以包括CRS、CSI-RS以及主、辅同步信号中的至少一个或多于一个。Of course, in addition to sending CRS to the UE, the base station can also send other identification signals to the UE, such as the base station can send a channel state information reference signal (CSI-RS, Channel-State Information-ReferenceSignal) to the UE, or send one or more of the discovery signals (Discovery Reference Signal) to the UE. The discovery signal may include at least one or more of CRS, CSI-RS, and primary and secondary synchronization signals.
可以理解的是，基站通过向UE发送消息，将该基站在该转换间隔或该目标符号处进行波束切换的信息发送给UE后，UE可以确定基站的波束切换情况。如，基站可以在发送该消息的同时，将转换间隔和目标符号所对应的时刻通知给UE，UE结合确定出的波束切换情况以及波束发生改变的时刻，从而使得UE可以确定出能够接收到的模拟波束的时间段，进而可以根据需要在UE无需接收模拟波束的时间段内，将UE设置为休眠状态。It can be understood that after the base station sends a message to the UE, and sends the information that the base station performs beam switching at the switching interval or the target symbol to the UE, the UE can determine the beam switching status of the base station. For example, the base station can notify the UE of the time corresponding to the switching interval and the target symbol while sending the message, and the UE combines the determined beam switching status and the time when the beam changes, so that the UE can determine the time period of the simulated beam that can be received, and then the UE can be set to a sleep state during the time period when the UE does not need to receive the simulated beam as needed.
当然，UE还可以基于基站发送的消息做其他的处理。Of course, the UE may also perform other processing based on the message sent by the base station.
如，对于消息中包括CRS的情况而言，由于UE可以通过测量CRS，来判断小区的信号质量。在测量CRS过程中，会连续测量多个子帧甚至多个帧的CRS信号强度，并计算测量得到的CRS的平均信号强度，然后将CRS的平均信号强度上报给基站。这样，当采用模拟波束发送CRS信号时，UE需要区分测量的不同模拟波束所对应的CRS信号强度，并统计该UE所处波束发射方向上的模拟波束的CRS强度，然后上报给基站；而如果UE不知道该多个字符中转换间隔前后的波束发射方向不同，则会把转换间隔前后不同发射方向的模拟波束作为同一个模拟波束而计算CRS的平均信号强度，从而导致上报给基站的CRS的平均信号强度出错。For example, in the case where the message includes CRS, since the UE can determine the signal quality of the cell by measuring CRS. In the process of measuring CRS, the CRS signal strength of multiple subframes or even multiple frames will be continuously measured, and the average signal strength of the measured CRS will be calculated, and then the average signal strength of the CRS will be reported to the base station. In this way, when using an analog beam to send a CRS signal, the UE needs to distinguish the CRS signal strengths corresponding to different measured analog beams, and count the CRS strengths of the analog beams in the beam transmission direction where the UE is located, and then report them to the base station; if the UE does not know that the beam transmission directions before and after the transition interval in the multiple characters are different, the analog beams in different transmission directions before and after the transition interval will be regarded as the same analog beam and the average signal strength of the CRS will be calculated, resulting in an error in the average signal strength of the CRS reported to the base station.
可以理解的是，基站发送消息的形式也可以有多种形式，如，消息可以通过物理下行控制信道(PDCCH，Physical Downlink Control Channel)动态传输的信令；又如，消息可以为通过该高层无线资源控制(RRC，Radio Resource Control)传输的信令。It is understandable that the base station may send messages in various forms, for example, the message may be a signaling dynamically transmitted via the physical downlink control channel (PDCCH); or, for example, the message may be a signaling transmitted via the high-level radio resource control (RRC) .
