LBT and not doing LBT etc. Since the high-frequency band is relatively high, the LBT method on the unlicensed spectrum on the high-frequency band is different from the LBT method on the unlicensed spectrum on the traditional frequency band. Therefore, how to support the NR-U system on the high-frequency band based on transceiver The interactive channel or signal transmission is an urgent problem to be solved.

NR系统目前主要考虑两个频段,FR1(Frequency range 1)和FR2(Frequency range 2),作为一个示例,FR1和FR2包括的频域范围如表1所示。The NR system currently mainly considers two frequency bands, FR1 (Frequency range 1) and FR2 (Frequency range 2). As an example, the frequency domain ranges included in FR1 and FR2 are shown in Table 1.
表1Table 1
随着NR系统的演进,新的频段例如高频上的技术也开始进行研究。新频段包括的频域范围如表2所示,为便于描述,本申请中用FRX表示,应理解,该频段名称不应构成任何限定。例如,FRX可以为FR3。With the evolution of NR systems, new frequency bands such as high-frequency technologies have also begun to be studied. The frequency domain range included in the new frequency band is shown in Table 2. For the convenience of description, it is represented by FRX in this application. It should be understood that the name of the frequency band should not constitute any limitation. For example, FRX could be FR3.
表2:新频段范围Table 2: New frequency band range
FRX频段中包括授权频谱,也包括非授权频谱。或者说,FRX频段中包括非共享频谱或专用频谱,也包括共享频谱。The FRX frequency band includes licensed spectrum and unlicensed spectrum. In other words, the FRX frequency band includes non-shared spectrum or dedicated spectrum, and also includes shared spectrum.
非授权频谱是国家和地区划分的可用于无线电设备通信的频谱,该频谱通常被认为是共享频谱,即不同通信系统中的通信设备只要满足国家或地区在该频谱上设置的法规要求,就可以使用该频谱,不需要向政府申请专有的频谱授权。The unlicensed spectrum is the spectrum allocated by the country and region that can be used for radio device communication. This spectrum is usually considered a shared spectrum, that is, communication devices in different communication systems can be used as long as they meet the regulatory requirements set by the country or region on the spectrum. To use this spectrum, there is no need to apply to the government for exclusive spectrum authorization.
为了让使用非授权频谱进行无线通信的各个通信系统在该频谱上能够友好共存,一些国家或地区规定了使用非授权频谱必须满足的法规要求。例如,通信设备遵循“先听后说(LBT)”原则,即通信设备在非授权频谱的信道上进行信号发送前,需要先进行信道侦听,只有当信道侦听结果为信道空闲时,该通信设备才能进行信号发送;如果通信设备在非授权频谱的信道上的信道侦听结果为信道忙,该通信设备不能进行信号发送。又例如,为了保证公平性,在一次传输中,通信设备使用非授权频谱的信道进行信号传输的时长不能超过一定时间长度。又例如,为了避免在非授权频谱的信道上传输的信号的功率太大,影响该信道上的其他重要信号的传输,通信设备使用非授权频谱的信道进行信号传输时需要遵循不超过最大功率谱密度的限制。需要说明的是,在某些国家或地区,对于FRX频段中包括的非授权频谱,没有LBT的要求。In order to allow various communication systems that use unlicensed spectrum for wireless communication to coexist friendly on this spectrum, some countries or regions have stipulated regulatory requirements that must be met when using unlicensed spectrum. For example, the communication device follows the "listen before talking (LBT)" principle, that is, the communication device needs to perform channel detection before sending signals on the channel of the unlicensed spectrum. Only when the channel detection result indicates that the channel is idle, the Only the communication device can send the signal; if the result of the channel detection of the communication device on the channel of the unlicensed frequency spectrum is that the channel is busy, the communication device cannot send the signal. For another example, in order to ensure fairness, in one transmission, the duration of signal transmission by the communication device using the channel of the unlicensed spectrum cannot exceed a certain period of time. For another example, in order to prevent the power of the signal transmitted on the channel of the unlicensed spectrum from being too large and affecting the transmission of other important signals on the channel, the communication device needs to follow the maximum power spectrum when using the channel of the unlicensed spectrum for signal transmission. Density limitations. It should be noted that in some countries or regions, there is no LBT requirement for the unlicensed spectrum included in the FRX frequency band.
非授权频谱上传输的基本概念:Basic concepts of transmission on unlicensed spectrum:
最大信道占用时间(MCOT):指在共享频谱的信道上信道检测(channel sensing)成功后允许使用该信道进行信号传输的最大时间长度。Maximum channel occupancy time (MCOT): refers to the maximum length of time allowed to use the channel for signal transmission after successful channel sensing on the shared spectrum channel.
信道占用时间(Channel Occupancy Time,COT):指在共享频谱的信道上信道检测成功后使用该信道进行信号传输的时间长度,也可以认为是在共享频谱的信道上信道检测成功后占用该信道的时间长度。其中,该时间长度内信号占用信道可以是连续的或不连续的,该时间长度包括发起信道占用的设备和共享信道占用的设备进行信号传输的总时间。Channel occupancy time (Channel Occupancy Time, COT): refers to the length of time that the channel is used for signal transmission after successful channel detection on the shared spectrum channel. length of time. Wherein, the channel occupied by the signal within the time length may be continuous or discontinuous, and the time length includes the total time for signal transmission by the device initiating the channel occupation and the device occupied by the shared channel.
网络设备的信道占用时间(gNB/eNB-initiated COT):也称为网络设备发起的COT,指网络设备在共享频谱的信道上信道检测成功后获得的一次信道占用时间。网络设备发起的COT内除了可以用 于网络设备进行传输,也可以在满足一定条件下用于终端设备进行传输。Channel occupancy time of network equipment (gNB/eNB-initiated COT): also known as COT initiated by network equipment, refers to a channel occupancy time obtained by a network equipment after successful channel detection on a shared spectrum channel. The COT initiated by the network device can not only be used for network device transmission, but also can be used for terminal device transmission under certain conditions.
终端设备的信道占用时间(UE-initiated COT):也称为终端设备发起的COT,指终端设备在共享频谱的信道上信道检测成功后获得的一次信道占用时间。终端设备发起的COT内除了可以用于终端设备进行传输,也可以在满足一定条件下用于网络设备进行传输。UE-initiated channel occupancy time (UE-initiated COT): also called UE-initiated COT, refers to the channel occupancy time obtained by the terminal equipment after successful channel detection on the channel of the shared spectrum. The COT initiated by the terminal device can not only be used for transmission by the terminal device, but also can be used by the network device for transmission if certain conditions are met.
下行传输机会(DL transmission burst):网络设备进行的一组下行传输(即包括一个或多个下行传输),该组下行传输为连续传输(即多个下行传输之间没有空隙),或该组下行传输中有空隙但空隙小于或等于预设值,例如在FR1频段上该预设值为16μs。如果网络设备进行的两个下行传输之间的空隙大于该预设值16μs,那么认为该两个下行传输属于两次下行传输机会。Downlink transmission opportunity (DL transmission burst): A group of downlink transmissions performed by network equipment (that is, including one or more downlink transmissions), the group of downlink transmissions is continuous transmission (that is, there is no gap between multiple downlink transmissions), or the group There is a gap in the downlink transmission but the gap is less than or equal to a preset value, for example, the preset value is 16 μs on the FR1 frequency band. If the gap between two downlink transmissions performed by the network device is greater than the preset value of 16 μs, then the two downlink transmissions are considered to belong to two downlink transmission opportunities.
上行传输机会(UL transmission burst):一个终端设备进行的一组上行传输(即包括一个或多个上行传输),该组上行传输为连续传输(即多个上行传输之间没有空隙),或该组上行传输中有空隙但空隙小于或等于预设值,例如在FR1频段上该预设值为16μs。如果该终端设备进行的两个上行传输之间的空隙大于该预设值16μs,那么认为该两个上行传输属于两次上行传输机会。Uplink transmission opportunity (UL transmission burst): A group of uplink transmissions performed by a terminal device (that is, including one or more uplink transmissions), and the group of uplink transmissions is continuous transmission (that is, there is no gap between multiple uplink transmissions), or the There is a gap in the group uplink transmission but the gap is less than or equal to a preset value, for example, the preset value is 16 μs on the FR1 frequency band. If the gap between the two uplink transmissions performed by the terminal device is greater than the preset value of 16 μs, it is considered that the two uplink transmissions belong to two uplink transmission opportunities.
应理解,在FRX频段,上述预设值可以为其他值,例如为8μs。本申请对此并不限定。It should be understood that, in the FRX frequency band, the foregoing preset value may be other values, such as 8 μs. This application is not limited to this.
信道检测成功:也称为LBT成功或信道检测空闲。例如对信道进行的监听时隙内的能量检测低于能量检测门限。Channel detection success: also known as LBT success or channel detection idle. For example, the energy detection performed on the channel in the listening time slot is lower than the energy detection threshold.
信道检测失败:也称为LBT失败或信道检测忙碌。例如对信道进行的监听时隙内的能量检测高于或等于能量检测门限。Channel detection failure: also known as LBT failure or channel detection busy. For example, the energy detection performed on the channel in the listening time slot is higher than or equal to the energy detection threshold.
接收侧辅助的信道接入Receiver-assisted channel access
接收侧辅助信道监听是一种基于请求发送/允许发送(Request To Send/Clear To Send,RTS/CTS)机制的LBT方式。如图2所示。网络设备在进行传输前,先发送一个类似于RTS的信号询问终端设备是否准备好进行数据接收。终端设备在收到RTS信号后,如果LBT过程成功,则可以向网络设备发送一个类似于CTS的信号例如上报自己的干扰测量结果,告知网络设备自己已准备好进行数据接收,网络设备在收到CTS后即可向终端设备进行下行传输。或者,如果终端有收设备没到RTS,或终端设备收到RTS但由于LBT过程失败不能发送CTS,则终端设备不会向网络设备发送CTS信号,网络设备在没有收到终端设备的CTS信号的情况下,可放弃向终端设备进行下行传输。Auxiliary channel monitoring at the receiving side is an LBT method based on a Request To Send/Clear To Send (RTS/CTS) mechanism. as shown in picture 2. Before the network device transmits, it first sends a signal similar to RTS to ask the terminal device whether it is ready to receive data. After the terminal device receives the RTS signal, if the LBT process is successful, it can send a signal similar to CTS to the network device, such as reporting its own interference measurement results, informing the network device that it is ready to receive data. After the CTS, downlink transmission can be performed to the terminal equipment. Or, if the receiving device of the terminal does not receive the RTS, or the terminal device receives the RTS but cannot send the CTS due to the failure of the LBT process, the terminal device will not send the CTS signal to the network device, and the network device does not receive the CTS signal of the terminal device. In this case, the downlink transmission to the terminal equipment may be abandoned.
FRX频段上的非授权频谱对应的信道接入Channel access corresponding to unlicensed spectrum on the FRX frequency band
在FRX频段上,对于有LBT要求的国家和地区,LBT方式(即信道接入方式)可以包括全向LBT、定向LBT、接收侧辅助LBT和不做LBT等几种方式。其中,对于不做LBT的信道接入方式,可能还需要受限于一定条件例如自动发射功率控制ATPC、DFS、长期干扰检测或其他干扰消除机制等。另外做LBT的信道接入和不做LBT的信道接入之间还可以进行切换。On the FRX frequency band, for countries and regions that require LBT, the LBT method (that is, the channel access method) can include omnidirectional LBT, directional LBT, auxiliary LBT on the receiving side, and no LBT. Among them, for channel access methods without LBT, certain conditions may also need to be limited, such as automatic transmit power control ATPC, DFS, long-term interference detection or other interference elimination mechanisms. In addition, it is also possible to switch between channel access with LBT and channel access without LBT.
对于没有LBT要求的国家和地区,也需要考虑是否要引入一定条件例如是否需要应用DFS、应用ATPC、应用长期干扰检测、限制一定的占空比(duty cycle)、限制一定的发射功率、限制MCOT等等。For countries and regions without LBT requirements, it is also necessary to consider whether to introduce certain conditions, such as whether to apply DFS, apply ATPC, apply long-term interference detection, limit a certain duty cycle (duty cycle), limit a certain transmit power, limit MCOT etc.
在引入FRX频段之后,由于频段比较高,FRX频段上的非授权频谱上的LBT方式和FR1频段上的非授权频谱上的LBT方式不同。例如,在FRX频段上可以引入基于收发交互的信道接入方式,也称为接收侧辅助信道接入方式。因此,如何在FRX频段上的NR-U系统中支持接收侧辅助信道接入(或称接收侧辅助信道检测,接收侧辅助LBT)方式是一项急需解决的问题。After the introduction of the FRX frequency band, due to the relatively high frequency band, the LBT method on the unlicensed spectrum on the FRX frequency band is different from the LBT method on the unlicensed spectrum on the FR1 frequency band. For example, a channel access method based on transceiving interaction can be introduced in the FRX frequency band, which is also called an auxiliary channel access method on the receiving side. Therefore, how to support the receiving-side auxiliary channel access (or called receiving-side auxiliary channel detection, receiving-side auxiliary LBT) method in the NR-U system on the FRX frequency band is an urgent problem to be solved.
