- Unlicensed spectrum is the spectrum that can be used for radio equipment communication divided by countries and regions. This spectrum is generally considered to be shared spectrum, that is, communication equipment in different communication systems can meet the regulatory requirements set by the country or region on the spectrum. Using this spectrum does not require applying for a proprietary spectrum license from the government. 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, in Europe, communication equipment follows the LBT principle, that is, communication equipment needs to perform channel listening before sending signals on channels with unlicensed spectrum.
- the communication equipment can perform Signal transmission; if the channel monitoring result of the communication device on the channel of the unlicensed spectrum is that the channel is busy, the communication device cannot perform signal transmission. And in order to ensure fairness, in one transmission, the communication device uses the channel of the unlicensed spectrum for signal transmission time not to exceed the maximum channel occupation time (MCOT, Maximum Channel Occupation Time).

本申请实施例的技术方案可以应用于各种通信***,例如:全球移动通讯(Global System of Mobile communication,GSM)***、码分多址(Code Division Multiple Access,CDMA)***、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)***、通用分组无线业务(General Packet Radio Service,GPRS)、长期演进(Long Term Evolution,LTE)***、LTE频分双工(Frequency Division Duplex,FDD)***、LTE时分双工(Time Division Duplex,TDD)、通用移动通信***(Universal Mobile Telecommunication System,UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access,WiMAX)通信***或5G***等。

可选地,终端120之间可以进行终端直连(Device to Device,D2D)通信。

应理解,本文中术语“***”和“网络”在本文中常被可互换使用。本文中术语“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。
为便于理解本申请实施例的技术方案,以下对本申请实施例相关的技术进行说明。
免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***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。为了让使用免授权频谱进行无线通信的各个通信***在该频谱上能够友好共存,一些国家或地区规定了使用免授权频谱必须满足的法规要求。例如,在欧洲地区,通信设备遵循LBT原则,即通信设备在免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;如果通信设备在免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。且为了保证公平性,在一次传输中,通信设备使用免授权频谱的信道进行信号传输的时长不能超过最大信道占用时间(MCOT,Maximum Channel Occupation Time)。
在免授权频谱的***中,基站发送下行信道需要进行LBT,且一次占用信道的时间有限制,因此下行信道和信号的传输有可能是不连续的。而终端并不知道基站何时开始占用下行信道进行传输,因此需要不断的检测下行信道,这样会造成终端的耗电。为了减少终端的耗电,在基站进行信道侦听的结果为空闲后,发送指示信号给终端,通知终端基站获得下行传输机会。终端收到该指示后,开始接收相应的下行信道和信号,例如PDCCH,参考信号等。在收到该指示之前,终端可以不检测除指示信号之外的信道和信号,或者以较长的周期检测包括指示信号在内的下行信道和信号。
另一方面,终端需要进行无线资源管理(RRM,Radio Resource Management)测量和无线链路监听(RLM,Radio Link Monitoring)测量,通过对信道状态信息参考信号(CSI-RS,Channel State Information-Reference Signal)或者同步信号(SS,synchronization signal)的参考信号接收功率(RSRP,Reference Signal Received Power)、参考信号接收质量(RSRQ,Reference Signal Received Quality)或者信号与干扰加噪声比(SINR,Signal-to-noise and Interference Ratio)行测量,进行移动性管理和同失步判决。或者,终端通过配置的CSI-RS进行信道状态的测量。
图2为本申请实施例提供的信号传输方法的流程示意图一,如图2所示,所述信号传输方法包括以下步骤:
步骤201:终端接收第一指示信号,基于所述第一指示信号确定测量结果有效的测量参考信号的时域、频域、码域中的至少一个。
本申请实施例中,所述终端可以是手机、平板电脑、车载终端、笔记本等任意能够网络进行通信的设备。
本申请实施例中,终端接收基站发送的第一指示信号,基于所述第一指示信号确定测量结果有效的测量参考信号的时域、频域、码域中的至少一个。这里,基站可以但不局限于是5G中的gNB。
本申请实施例中,所述第一指示信号指示测量结果有效的测量参考信号的时域、频域、码域中的至少一个,如此,终端可以确定出哪些位置上检测出的测量参考信号的测量结果是有效测量结果。
在一实施方式中,所述第一指示信号直接指示出需要检测的测量参考信号的时域、频域、码域中的至少一个,所述需要检测的测量参考信号对应的测量结果为有效测量结果,终端基于所述第一指示信号确定需要检测的测量参考信号的时域、频域、码域中的至少一个,进一步,终端仅在这些测量结果有效的测量参考信号的位置上对测量参考信号进行检测。
本申请实施例中,所述测量参考信号包括CSI-RS、TRS、同步信号和同步信号块中的至少一种。
在一实施方式中,所述第一指示信号为物理层信号或PDCCH承载的信息。进一步,所述物理层信号为参考信号。
这里,PDCCH承载的信息可以是优先抢占指示(Pre-emption Indication)信息。具体地,通过PDCCH承载Pre-emption Indication信息,Pre-emption Indication信息用于指示超高可靠超低时延通信(URLLC)业务的终端占用的时频资源位置,这个时频资源位置位于Pre-emption Indication信息发送之前调度给其他终端的物理下行共享信道(PDSCH)占用的区域,用于其他终端做确定其PDSCH实际占用的时频资源, 进一步实现速率匹配。本申请实施例利用Pre-emption Indication信息来指示测量结果有效的测量参考信号的时域、频域、码域中的至少一个。
本申请实施例中,考虑到非免授权频谱***中的LBT原则,基站在发送下行信道/信号的时候,需要首先进行LBT,LBT成功后,基站获得下行传输机会,对应地,终端侧是下行接收机会。基于此,所述第一指示信号用于指示下行传输机会的起始位置和/或下行传输机会的占用时间;或者,所述第一指示信号用于指示下行接收机会的起始位置和/或下行接收时间。上述方案中,测量结果有效的测量参考信号的时域位置包括下行传输机会占用时间内或下行接收时间内的测量参考信号的时域位置。
参照图3,基站进行LBT成功后,获得下行传输机会,通过第一指示信号通知终端下行传输机会的起始位置和/或下行传输机会的占用时间,从而终端可以确定出下行传输机会对应的时间范围,终端在下行传输机会对应的时间范围内对测量参考信号进行测量,这里,下行传输机会对应的时间长度不能超过MCOT,图3以一次下行传输机会对应的时间长度为MCOT为例,在MCOT结束后,终端在再次收到第一指示信号之前,不对测量参考信号进行测量,或者不上报测量结果给高层。
考虑到测量参考信号的时域位置是网络侧预配置的,因此,所述终端在所述下行传输机会占用时间内或下行接收时间内的测量参考信号的时域位置上,对所述测量参考信号进行检测。参照图3,在MCOT的时间内包括4个测量参考信号的时域位置,终端会在这4个测量参考信号的时域位置上检测测量参考信号。
本申请实施例中,所述终端将所述时域位置上对于所述测量参考信号的测量结果上报给高层。进一步,所述测量参考信号用于RRM测量、或RLM测量、或同步、或信道状态测量、或时频跟踪。

本申请实施例中,基站向终端发送第一指示信号,所述终端可以是手机、平板电脑、车载终端、笔记本等任意能够网络进行通信的设备。
本申请实施例中,所述第一指示信号指示测量结果有效的测量参考信号的时域、频域、码域中的至少一个,如此,终端可以确定出哪些位置上检测出的测量参考信号的测量结果是有效测量结果。
在一实施方式中,所述第一指示信号直接指示出需要检测的测量参考信号的时域、频域、码域中的至少一个,所述需要检测的测量参考信号对应的测量结果为有效测量结果,可见,所述第一指示信号用于终端确定需要检测的测量参考信号的时域、频域、码域中的至少一个。
本申请实施例中,所述测量参考信号包括CSI-RS、TRS、同步信号和同步信号块中的至少一种。
在一实施方式中,所述第一指示信号为物理层信号或PDCCH承载的信息。进一步,所述物理层信号为参考信号。
这里,PDCCH承载的信息可以是优先抢占指示(Pre-emption Indication)信息。具体地,通过PDCCH承载Pre-emption Indication信息,Pre-emption Indication信息用于指示超高可靠超低时延通信(URLLC)业务的终端占用的时频资源位置,这个时频资源位置位于Pre-emption Indication信息发送之前调度给其他终端的PDSCH占用的区域,用于其他终端做确定其PDSCH实际占用的时频资源,从而进一步实现速率 匹配。本申请实施例利用Pre-emption Indication信息来指示测量结果有效的测量参考信号的时域、频域、码域中的至少一个。
本申请实施例中,考虑到非免授权频谱***中的LBT原则,基站在发送下行信道/信号的时候,需要首先进行LBT,LBT成功后,基站获得下行传输机会,对应地,终端侧是下行接收机会。基于此,所述第一指示信号用于指示下行传输机会的起始位置和/或下行传输机会的占用时间;或者,所述第一指示信号用于指示下行接收机会的起始位置和/或下行接收时间。上述方案中,测量结果有效的测量参考信号的时域位置包括下行传输机会占用时间内或下行接收时间内的测量参考信号的时域位置。
参照图3,基站进行LBT成功后,获得下行传输机会,通过第一指示信号通知终端下行传输机会的起始位置和/或下行传输机会的占用时间,从而终端可以确定出下行传输机会对应的时间范围,终端在下行传输机会对应的时间范围内对测量参考信号进行测量,这里,下行传输机会对应的时间长度不能超过MCOT,图3以一次下行传输机会对应的时间长度为MCOT为例,在MCOT结束后,终端在再次收到第一指示信号之前,不对测量参考信号进行测量,或者不上报测量结果给高层。
考虑到测量参考信号的时域位置是网络侧预配置的,因此,所述终端在所述下行传输机会占用时间内或下行接收时间内的测量参考信号的时域位置上,对所述测量参考信号进行检测。参照图3,在MCOT的时间内包括4个测量参考信号的时域位置,终端会在这4个测量参考信号的时域位置上检测测量参考信号。
