To use this spectrum, there is no need to apply for an exclusive spectrum license from the government.
- a communication device follows the "Listen Before Talk (LBT)" principle, that is, before a communication device transmits a signal on an unlicensed spectrum channel, it needs to perform channel detection first, and only when the channel detection result is that the channel is idle , the communication device can send the signal; if the channel detection result of the communication device on the channel of the unlicensed spectrum is that the channel is busy, the communication device cannot send the signal.

Wherein, the signal occupying the channel may be continuous or discontinuous within the time length, and the time length includes the total time for signal transmission by the device initiating the channel occupation and the device sharing the channel occupation.
- Channel occupation time of network equipment also known as COT initiated by network equipment, it refers to a channel occupation time obtained by network equipment after successful channel detection on the channel of the shared spectrum.

- Channel Detection Failed Also known as LBT Failure or Channel Detection Busy.
- the energy detection in the listening slot on the channel is higher than or equal to the energy detection threshold.
- Auxiliary channel monitoring on the receiving side is an LBT method similar to the Request To Send/Clear To Send (RTS/CTS) mechanism of the Wi-Fi system.
- RTS/CTS Request To Send/Clear To Send
- the network device before transmitting, the network device first sends an RTS message to inquire whether the terminal device is ready to receive data. After the terminal device receives the RTS message, if the LBT process is successful, it can send a CTS-like message to the network device, such as reporting its own interference measurement results to inform the network device that it is ready to receive data. After the CTS message, downlink transmission can be performed to the terminal device.
- RTS/CTS Request To Send/Clear To Send
- the terminal device if the terminal device does not receive the RTS message, or the terminal device receives the RTS message but cannot send the CTS message due to the failure of the LBT process, the terminal device will not send the CTS message to the network device, and the network device will not receive the CTS message from the terminal device. In the case of a message, the downlink transmission to the terminal device can be abandoned.
- the LBT mode (ie, the channel access mode) can include omnidirectional LBT, directional LBT, receiving-side auxiliary LBT, and no LBT.
- the channel access method without LBT it may also need to be limited by, for example, automatic transmit power control (Automatic Transfer Power Control, ATPC), dynamic frequency selection (Dynamic frequency selection, DFS), long-term interference detection or other interference elimination. mechanism and other conditions.
- switching can be performed between channel access with LBT and channel access without LBT.

- a channel access method based on transceiver interaction which is also called an auxiliary channel access method on the receiving side, may be introduced on the FRX. If the NR-U system on the FRX frequency band is to support the way of assisting the LBT on the receiving side, when the terminal device receives the request to send information, how to send the corresponding response information, there is no clear solution at present.

在对本发明实施例提供的无线通信方法进行详细说明之前,先对高频段进行说明。
NR系统的研究目前主要考虑两个频段,FR1和FR2,其中,FR1和FR2包括的频域范围如表1所示。
表1、FR1和FR2定义
频段定义 | 对应频段范围 |
FR1 | 410MHz–7.125GHz |
FR2 | 24.25GHz–52.6GHz |
随着NR系统的演进,新的频段即高频上的技术也开始进行研究。为便于描述,本发明中用FRX表示高频段,高频段包括的频域范围如表2所示。应理解,该高频段名称不应构成任何限定。例如,FRX可以为FR3。
表2、FRX定义
频段定义 | 对应频段范围 |
FRX | 52.6GHz–71GHz |
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。
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。
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(Listen Before Talk,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,需要先进行信道检测,只有当信道检测结果为信道空闲时,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检测结果为 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。
FRX频段考虑的子载波间隔可以比FR2的子载波间隔更大,目前的候选子载波间隔包括以下几种中的至少一种:240kHz、480kHz、960kHz、1.902MHz、3.84MHz。作为示例,这些候选子载波间隔下对应的参数集(Numerology)如下表3所示。
表3、FRX频段的候选子载波间隔对应的参数集示例
子载波间隔 | 符号长度 | NCP长度 | ECP长度 | 符号带NCP长度 | 时隙长度 |
240kHz | 4.16μs | 0.2902μs | 1.04μs | 4.452μs | 62.5μs |
480kHz | 2.08μs | 0.146μs | 0.52μs | 2.226μs | 31.25μs |
960kHz | 1.04μs | 0.073μs | 0.26μs | 1.113μs | 15.625μs |
下面,对共享频谱的部分概念进行介绍。
最大信道占用时间(Maximum Channel Occupation Time,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。
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。
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。
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。
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16微秒(μs)。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。
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。
应理解,在FRX频段,上述预设值可以为其他值,例如为8μs。本发明对此并不限定。
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。
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。
接收侧辅助信道监听是一种类似于Wi-Fi系统的请求发送/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RTS消息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消息后,如果LBT过程成功,则可以向网络设备发送一个类似于CTS消息,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消息后即可向终端设备进行下行传输。或者,如果终端设备没有收到RTS消息,或终端设备收到RTS消息但由于LBT过程失败不能发送CTS消息,则终端设备不会向网络设备发送CTS消息,网络设备在没有收到终端设备的CTS消息的情况下,可放弃向终端设备进行下行传输。
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,可能还需要受限于例如自动发射功率控制(Automatic Transfer Power Control,ATPC)、动态频率选择(Dynamic frequency selection,DFS)、长期干扰检测或其他干扰消除机制等一定条件。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。
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。
由于FRX的频段比较高,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。如果要在FRX频段上的NR-U系统中支持接收侧辅助LBT的方式,当终端设备接收到请求发送信息后,如何发送对应的应答信息,目前还没有明确方案。为此,提出了本发明实施例的以下技术方案,本发明实施例的技术方案可以但不局限于应用于FRX上的非授权频谱上。
为便于理解本发明实施例的技术方案,以下通过具体实施例详述本发明的技术方案。以上相关技术作为可选方案与本发明实施例的技术方案可以进行任意结合,其均属于本发明实施例的保护范围。本发明实施例包括以下内容中的至少部分内容。

作为示例,第一频域资源为终端设备被配置的激活BWP上的第一频域资源集合,第一频域资源集合包括至少一个频域资源集合,其中,一个频域资源集合可以为一个资源块RB集合。如图6所示,终端设备的激活BWP上包括4个RB集合,分别为RB集合0~3。相应地,终端设备发送的应答信息中包括4个比特,分别与该4个RB集合一一对应。当终端设备收到关联该4个RB集合中的RB集合0和1的传输请求信息时(作为示例,在图中以RTS表示),终端设备向网络设备发送的应答信息如下表4所示(作为示例,在图中以CTS表示)。网络设备在收到终端设备发送的应答信息后,可以通过RB集合0和1中的资源向该终端设备发送下行传输。
表4、应答信息示例
RB集合0 | RB集合1 | RB集合2 | RB集合3 |
ACK | ACK | NACK | NACK |
在一些实施例中,应答信息可以通过参考信号序列,例如PRACH序列或SRS序列来携带。当终端设备向网络设备发送该参考信号序列,则说明该终端设备向网络设备发送允许传输的应答信息。
在一些实施例中,如果终端设备没有收到第一控制信息,则不向网络设备发送应答信息。
在一些实施例中,如果终端设备没有收到第一控制信息,则在预配置或预定义的时频资源上向网络设备发送NACK信息。例如,在半静态信道占用的信道接入机制中,用于发送应答信息的资源可以是预配置或预定义的且是周期出现的,在这种情况下,如果终端设备没有收到第一控制信息,则可以在对应的应答资源上发送NACK信息。
在一些实施例中,所述第一控制信息是终端设备专用的控制信息例如通过UE-specific PDCCH传输的DCI。
在一些实施例中,所述第一控制信息是公共或组公共的控制信息例如通过Group-common PDCCH传输的DCI。
