Description

一种通信方法、装置和系统 技术领域
本申请涉及通信领域。
背景技术
与传统的3G(第三代移动通信技术)、4G(第四代移动通信技术)系统相比,5G(第五代移动通信技术)系统能够提供更大的带宽以及更高的数据率,并且能够支持更多类型的终端和垂直行业业务。为此,5G系统的现有部署频率通常高于3G和4G系统。例如,5G系统可以部署在毫米波波段。
然而,承载频率越高,信号在传输过程中经历的衰落越严重。因此,在5G系统的实际部署中,特别是在毫米波段,如何更好的增强小区覆盖,成为亟待解决的问题。
应该注意,上面对技术背景的介绍只是为了方便对本申请的技术方案进行清楚、完整的说明,并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本申请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
为了更好的解决蜂窝移动通信系统在实际部署中的覆盖问题,采用射频转发器(RF Relay/Repeater)放大和转发终端设备与网络设备之间的通信信号,是比较常用的部署手段。射频转发器在3G系统和4G系统的实际部署中具有较为广泛的应用。通常来说,射频转发器是一种在射频域放大和转发网络设备与终端设备往来信号的设备。
射频转发器可以部署在TDD(时分双工)网络中。在3G系统和4G系统的部署中,TDD网络的帧结构一旦规划好,即会在很长一段时间内保持、不发生变化。传统射频转发器不具备与网络设备通信的功能,无法从网络设备获取任何辅助信息。它一旦被部署在TDD网络中,需要自行对网络的帧结构,也即上行、下行信号的传输时间,进行探测和估计,而后根据其估计结果对上行、下行信号进行转发。
在5G系统中,为了支持更多、更灵活的应用场景,5G系统的帧结构/时隙结构可以被更为灵活地配置,甚至同一个小区的不同用户可以使用不同的帧结构/时隙结 构与同一个网络设备进行通信。
发明人发现,针对5G系统在部署中遇到的覆盖问题,采用射频转发器进行覆盖增强是可行的解决方案之一。但是,传统射频转发器通过自行探测获得上下行信号传输时间的方法无法很好地适应5G系统灵活的部署场景。转发器对上下行信号传输时间的任何错误估计,都可能导致必要信号得不到正确的转发以及不必要的信号被错误的放大造成额外的干扰,进而降低信号的接收信噪比,导致整个网络的吞吐量的下降。例如,转发器错误地将上行信号传输时间估计为下行信号传输时间,并在该时间切换至下行信号转发链路,导致上行信号未能被正确转发,而下行信号方向的噪声和干扰被转发器放大。
为了解决上述问题,本申请实施例提供了一种通信方法、装置和系统,使得转发器可以在网络设备的指示下更好地实现转发信号的功能。此外,为了从网络设备处获得指示,转发器需要具备与网络设备进行通信(或者,交互信息)的功能。本申请实施例提供的方法,还可以使得转发器在进行转发的同时与网络设备进行通信,以便接收来自网络设备的指示更好地实现转发信号的功能。

下面结合附图对本申请实施例的各种实施方式进行说明。这些实施方式只是示例性的,不是对本申请的限制。

在本申请实施例中,转发器在对接收的信号进行转发之前,还可以对该接收的信号进行处理。
例如,转发器通过对上述第一接收信号进行处理得到第一信号,这里的处理可以包括转发器对该第一接收信号进行放大的处理,但本申请不限于此,这里的处理还可以包括其他处理。
再例如,转发器在接收的来自网络设备的第二信号之后,可以对该第二信号进行处理后再进行转发,这里的处理可以包括转发器对该第二信号进行放大的处理,但本申请不限于此,这里的处理还可以包括其他处理。
在本申请实施例中,转发器对接收的信号进行转发,可以包括转发器不对接收的信号进行解调和解码,而仅对接收的信号进行前述处理(例如放大处理)。
例如,转发器转发第一信号包括:转发器不对上述第一接收信号进行解调和解码,仅对该第一接收信号进行上述处理(例如放大处理)得到第一信号,并将该第一信号(例如放大后的第一接收信号)发送给网络设备。
再例如,转发器转发处理后的第二信号包括:转发器不对接收的该第二信号进行解调和解码,仅对接收的第二信号进行上述处理(例如放大处理)后,发送处理后的第二信号。
在本申请实施例中,为了从网络设备处获得指示,转发器需要具备与网络设备进行通信(或者,交互信息)的功能。转发器还可以根据网络设备的指示向网络设备发送上行信号或从网络设备接收下行信号,即与网络设备进行上行通信或下行通信。
在一些实施例中,转发器还可以接收来自网络设备的第二指示信息,该第二指示信息用于指示第二时间单位用于转发器向网络设备发送由转发器生成的上行信号,该第二时间单位是上述TDD上下行配置中的上行时间单位和/或灵活时间单位。或者说,第二指示信息用于将上述TDD上下行配置中的第二时间单位重定义(redefine/override)为用于转发器向网络设备发送由该转发器生成的上行信号的时间单位。也 即,网络设备通过第二指示信息将上述TDD上下行配置中的上行时间单位和/或灵活时间单位中的至少部分指示为用于转发器进行上行通信的第二时间单位。其中,第二时间单位不用于转发器进行上行转发,但本申请不限于此,该第二时间单位也可以用于转发器进行上行转发。此外,未被第二指示信息重定义的上行时间单位仅用于转发器进行上行转发,而不用于转发器进行上行通信(也即,发送由转发器生成的上行信号)。
在上述实施例中,第二时间单位的数量可以是一个或者大于一个,在大于一个的情况下,该大于一个第二时间单位可以是连续的,也可以是不连续的。
在上述实施例中,在上述TDD上下行配置中的上述一组时间单位是周期性的情况下,第二指示信息还用于指示上述TDD上下行配置中的该一组时间单位的每个周期或者指定周期中的第二时间单位用于转发器向网络设备发送由该转发器生成的上行信号。也即,网络设备通过上述第二指示信息指示一组时间单位的每个周期或者指定周期中的第二时间单位用于转发器进行上行通信。直到有新的指令重新指示该第二时间单位的用途为止。
在上述实施例中,第二指示信息可以是PDCCH,也可以是高层信令。这里,PDCCH可以是公共(common)PDCCH,也可以是专用(dedicated)信令。这里,公共PDCCH例如为PDCCH format 2_0或者PDCCH format 2_x,本申请对x的取值不做限制。这里,高层信令可以是公共的,也可以是专用的。例如,第二指示信息是公共PDCCH。又例如,第二指示信息是专用高层信令。
在上述实施例中,第二时间单位不用于转发器进行上行转发,即,第二时间单位不用于转发器向网络设备转发前述第一信号;或者,第二时间单位不用于转发器接收用于得到所述第一信号的上述第一接收信号,即,转发器不在被配置为用于转发器进行上行通信的时间单位(第二时间单位)接收用于得到上述第一信号的上述第一接收信号。但如前所述,本申请不限于此,该第二时间单位也可以用于转发器进行上行转发。
在一些实施例中,转发器还可以接收来自网络设备的第三指示信息,该第三指示信息用于指示转发器在第三时间单位发送该转发器生成的第三信号,该第三时间单位为上述TDD上下行配置中的灵活时间单位和/或上行时间单位。与第二指示信息指示用于进行上行通信的第二时间单位不同,本实施例通过第三指示信息指示转发器在哪 些时间单位(第三时间单位)进行上行通信(也即发送第三信号),通过指示转发器在第三时间单位发送第三信号,隐式地指示了用于上行通信的时间单位。其中,第三时间单位不用于转发器进行上行转发,但本申请不限于此,该第三时间单位也可以用于转发器进行上行转发。此外,未被第三指示信息指示的上行时间单位仅用于转发器进行上行转发,不用于转发器进行上行通信(也即,发送由转发器生成的上行信号)。
在上述实施例中,第三时间单位为一个或一个以上的时间单位,或者为周期性的一个或一个以上的时间单位。
在上述实施例中,在第三时间单位为一个或一个以上的时间单位的情况下,第三指示信息可以是PDCCH,第三信号可以是以下至少之一:动态物理上行共享信道(PUSCH)、探测参考信号(SRS)、物理随机接入信道(PRACH)、物理上行控制信道(PUCCH)、激活的配置授权(CG)PUSCH。
在上述实施例中,在第三时间单位是一个周期的一个时间单位的情况下,第三指示信息可以是高层信令,第三信号可以是以下至少之一:PRACH、PUCCH、解调参考信号(DMRS)。本申请对该高层信令不做限制,可以是MAC信令,也可以是RRC信令,等,本申请不限于此。
在上述实施例中,在第三时间单位是周期性的一个或一个以上的时间单位的情况下,第三指示信息可以是高层信令,第三信号可以是配置授权(CG)PUSCH和/或SRS。其中,高层信令例如可以为MAC信令或者RRC信令,等。
在上述实施例中,第三信号(也即转发器与网络设备的上行通信)可以承载信道状态信息,这里的信道状态信息可以通过以下的一种或者一种以上的测量获得:
根据所述网络设备的配置基于SRS的测量;
根据所述网络设备的配置基于信道状态信息参考信号(CSI-RS)的测量;
根据所述网络设备的配置基于同步信号块(SSB)的测量;
根据所述网络设备的配置基于定位参考信号(PRS)的测量;以及
根据所述网络设备的配置基于交叉链路干扰参考信号(CLI-RS)的测量。
在上述实施例中,转发器可以基于网络设备的上述配置,将根据相应的测量得到的信道状态信息通过第三信号上报给网络设备。本申请对测量的方法不做限制,可以参考相关技术。
在上述实施例中,第三信号可以是随机接入信道(RACH),第三指示信息可以 是以下至少之一:系统信息、高层控制信息以及PDCCH。也即,网络设备可以通过系统信息、高层控制信息和/或PDCCH指示转发器用于发送RACH的时间单位(第三时间单位)。并且,转发器可以根据网络设备的指示,在第三时间单位向网络设备发送RACH。该RACH用于所述转发器进行随机接入、资源请求、RRC重建立等目的,本申请不以此为限。
在上述实施例中,第三时间单位不用于转发器进行上行转发,即,第三时间单位不用于转发器向网络设备转发上述第一信号;或者,第三时间单位不用于转发器接收用于得到上述第一信号的上述第一接收信号,即,转发器不在被配置为用于转发器进行上行通信的时间单位(第三时间单位)接收用于得到上述第一信号的上述第一接收信号。但如前所述,本申请不限于此,该第三时间单位也可以用于转发器进行上行转发。
在上述实施例中,转发器还可以根据网络设备的信息(例如第三指示信息)生成用于发送给网络设备的信号(例如第三信号),该用于发送给网络设备的信号(例如第三信号)用于承载该转发器发送给网络设备的信息和/或数据(例如前述的信道状态信息),和/或,用于所述网络设备对从转发器到网络设备的信道和/或信号进行测量和/或估计。本申请对具体的测量和/或估计方法不做限制,可以参考相关技术。
根据前述实施例,在一种实现方法中,转发器可以在不同时间进行上行通信和上行转发。例如第二时间单位和/或第三时间单位不用于转发器进行上行转发。网络设备指示除第二时间单位和/或第三时间单位以外的时间单位用于转发器进行上行转发。由此,上行通信与上行转发时分复用。这种实现方法,对设备的要求较低,有助于降低转发器的实现成本。而实现成本的降低有助于未来转发器设备在网络部署中的应用,也有利于以较小的代价增强网络部署(例如提高网络覆盖)。
在又一种实现方法中,转发器可以在一个时间单位进行上行通信,也可以在这个时间单位进行上行转发。例如第二时间单位和/或第三时间单位用于转发器进行上行转发。这种实现方法,网络设备可以指示转发器在任何上行和/或灵活时间单位进行上行转发,有利于保证转发效率,进而提高频谱使用效率。
在本申请实施例中,上述TDD上下行配置中的下行时间单位D还可以用于转发器接收来自网络设备的发送给自己的下行信号。也即,在一些实施例中,在同一个时间单位中转发器可以进行下行转发(也即转发器接收来自网络设备的信号,对该信号 进行处理后转发出去),也可以进行下行通信(也即转发器接收来自网络设备的信号,从中获取发送给自己的信号。
在又一些实施例中,转发器还可以接收来自网络设备的第四指示信息,该第四指示信息用于指示第四时间单位用于转发器接收网络设备发送给转发器的下行信号,该第四时间单位为上述TDD上下行配置中的下行时间单位和/或灵活时间单位。或者说,第四指示信息用于将上述TDD上下行配置中的第四时间单位重定义(redefine/override)为用于转发器接收网络设备发送给该转发器的下行信号的时间单位。也即,网络设备通过第四指示信息将上述TDD上下行配置中的下行时间单位和/或灵活时间单位中的至少部分指示为用于转发器进行下行通信的第四时间单位。其中,第四时间单位不用于转发器进行下行转发,但本申请不限于此,第四时间单位也可以用于转发器进行下行转发。此外,未被第四指示信息重定义的下行时间单位仅用于转发器进行下行转发,不用于转发器进行下行通信(也即,接收来自网络设备的发送给自己的下行信号)。
在上述实施例中,第四时间单位的数量可以是一个或者大于一个,在大于一个的情况下,该大于一个第四时间单位可以是连续的,也可以是不连续的。
在上述实施例中,在上述TDD上下行配置的上述一组时间单位是周期性的情况下,第四指示信息还用于指示上述TDD上下行配置中的该一组时间单位的每个周期或指定周期中的第四时间单位用于转发器接收网络设备发送给该转发器的下行信号。也即,网络设备通过上述第四指示信息指示一组时间单位的每个周期或指定周期中的第四时间单位用于转发器进行下行通信。直到有新的指令重新指示该第四时间单位的用途为止。
在上述实施例中,第四指示信息可以是PDCCH,也可以是高层信令。这里,PDCCH可以是公共(common)PDCCH,也可以是专用(dedicated)信令。这里,公共PDCCH例如为PDCCH format 2_0或者PDCCH format 2_x,本申请对x的取值不做限制。这里,高层信令可以是公共的,也可以是专用的。例如,第四指示信息是公共PDCCH。又例如,第四指示信息是专用高层信令。
在上述实施例中,第四指示信息和第二指示信息可以通过同一个信令承载,也即,通过一个信令指示第二时间单位和第四时间单位。关于第二时间单位和第四时间单位的相关内容,已经在前面做了说明,此处不再赘述。
例如,第四指示信息还用于指示第二时间单位用于转发器向网络设备发送由转发器生成的上行信号,该第二时间单位为上述TDD上下行配置中的上行时间单位和/或灵活时间单位。也即,网络设备可以通过第四指示信息同时指示上述第二时间单位和上述第四时间单位,例如,将上述TDD上下行配置中的上行时间单位和/或灵活时间单位指示为用于转发器进行上行通信的第二时间单位,并将上述TDD上下行配置中的下行时间单位和/或灵活时间单位指示为用于转发器进行下行通信的第四时间单位。
又例如,第一指示信息为包含tdd-UL-DL-ConfigurationCommon的高层信令,用于指示TDD上下行配置,第四指示信息为包含tdd-UL-DL-ConfiguratingDedicated的高层信令,用于指示上述第二时间单位和上述第四时间单位。
又例如,第一指示信息为包含tdd-UL-DL-ConfigurationCommon的高层信令,用于指示TDD上下行配置,第四指示信息为包含tdd-UL-DL-ConfiguratingDedicated的高层信令和/或物理控制信道DCI format 2_x(或者DCI format 2_0),用于指示上述第二时间单位和上述第四时间单位。
又例如,第一指示信息为包含tdd-UL-DL-ConfigurationCommon的高层信令和/或包含tdd-UL-DL-ConfiguratingDedicated的高层信令,用于指示TDD上下行配置,第四指示信息为物理控制信道DCI format 2_x(或者DCI format 2_0),用于指示上述第二时间单位和上述第四时间单位。
在上述实施例中,第一指示信息和第四指示信息可以通过同一个信令来承载,也即,通过一个信令指示TDD上下行配置和第四时间单位,或者,通过一个信令指示TDD上下行配置、第二时间单位以及第四时间单位。
例如,包含tdd-UL-DL-ConfiguratingDedicated的高层信令用于指示上述TDD上下行配置以及第二时间单位和第四时间单位。
又例如,新的、为支持转发器而引入标准的(例如包含SR字节)高层信令用于指示上述TDD上下行配置以及第二时间单位和第四时间单位。
关于TDD上下行配置、第二时间单位和第四时间单位的相关内容,已经在前面做了说明,此处不再赘述。
在一些实施例中,转发器还可以接收来自网络设备的第五指示信息,该第五指示信息用于指示转发器在第五时间单位接收来自网络设备的第五信号,该第五时间单位 为上述TDD上下行配置中的灵活时间单位和/或下行时间单位。与第四指示信息指示用于进行下行通信的第四时间单位不同,本实施例通过第五指示信息指示转发器在哪些时间单位(第五时间单位)进行下行通信(也即接收第五信号),通过指示转发器在第五时间单位接收第五信号,隐式地指示了用于下行通信的时间单位。其中,第五时间单位不用于转发器进行下行转发,但本申请不限于此,该第五时间单位也可以用于转发器进行下行转发。此外,未被第五指示信息指示的下行时间单位仅用于转发器进行下行转发,不用于转发器进行下行通信(也即,接收来自网络设备的发送给该该转发器的下行信号)。
在上述实施例中,第五信号用于转发器进行解调和解码以获取网络设备发送给自己的信息和/或数据,和/或,用于转发器对从所述转发器到所述网络设备的信道和/或信号进行估计和/或测量。
在上述实施例中,第五时间单位为一个或一个以上的时间单位,或者为周期性的一个或一个以上的时间单位。
在上述实施例中,在第五时间单位为一个或一个以上的时间单位的情况下,第五指示信息可以是PDCCH,第五信号可以是以下至少之一:PDSCH、相位跟踪参考信号(PTRS)、CSI-RS、SSB、SIB、激活的半静态PDSCH(SPS-PDSCH)。
在上述实施例中,在第五时间单位是周期性的一个或一个以上的时间单位的情况下,第五指示信息可以是高层信令,第五信号可以是以下至少之一:PDCCH、时间参考信号(TRS)、SSB、SIB、CSI-RS、半静态PDSCH(SPS-PDSCH)。
在上述实施例中,第五信号可以是SIB,第五指示信息可以是SSB和/或高层信令,本申请不限于此。
在上述实施例中,第五信号(也即转发器与网络设备的下行通信)可以承载网络设备向转发器指示空间滤波器的指示信息,这里的指示信息可以包括以下至少之一:
用于所述转发器接收第一接收信号的接收空间滤波器,所述第一接收信号用于得到所述第一信号;
用于所述转发器向所述网络设备转发所述第一信号的发送空间滤波器;
用于所述转发器接收所述第二信号的接收空间滤波器;
用于所述转发器转发处理后的所述第二信号的发送空间滤波器;
用于所述转发器向所述网络设备发送第三信号的发送空间滤波器,所述第三信号 为所述转发器生成的上行信号;以及
用于所述转发器接收来自所述网络设备的所述第五信号的接收空间滤波器。
在上述实施例中,用于转发器向网络设备转发第一信号的发送空间滤波器与用于转发器向网络设备发送第三信号的发送空间滤波器可以相同,但本申请不限于此。此外,用于转发器接收第二信号的接收空间滤波器和用于转发器接收来自网络设备的第五信号的接收空间滤波器可以相同,但本申请不限于此。
根据前述实施例,在一种实现方法中,转发器可以在不同的时间进行下行通信和下行转发。例如第四时间单位和/或第五时间单位不用于转发器进行下行转发。网络设备指示除第四时间单位和/或第五时间单位以外的时间单位用于转发器进行下行转发。由此,下行通信与下行转发时分复,有助于简化网络设备对无线资源的管理,进而降低网络设备的实现成本;并且,也能简化转发器的实现逻辑,降低转发器的成本。
在另一种实现方法中,转发器可以在一个时间单位进行下行通信,也可以在这个时间单位进行下行转发。例如第四时间单位和/或第五时间单位也用于转发器进行下行转发。这种实现方法对设备实现的要求不高,有助于减少网络设备的指示信令,提高无线资源的使用效率,进而提高网络吞吐量。
在一些实施例中,所述转发器不在所述TDD上下行配置中的所述上行时间单位向所述网络设备发送所述转发器生成的上行信号。例如,转发器在前述第二时间单位和/或第三时间单位向网络设备发送该转发器生成的上行信号/第三信号,前述第二时间单位是上述TDD上下行配置中的灵活时间单位,和/或,前述第三时间单位是上述TDD上下行配置中的灵活时间单位。
在一些实施例中,所述转发器不在所述TDD上下行配置中的所述上行时间单位向所述网络设备发送所述转发器生成的上行信号;并且,所述转发器不在所述TDD上下行配置中的所述下行时间单位接收来自所述网络设备的发送给所述转发器的下行信号。例如,转发器在前述第二时间单位和/或第三时间单位向网络设备发送该转发器生成的上行信号/第三信号,前述第二时间单位是上述TDD上下行配置中的灵活时间单位,和/或,前述第三时间单位是上述TDD上下行配置中的灵活时间单位。又例如,转发器在前述第四时间单位和/或第五时间单位接收来自网络设备的发送给自己的下行信号/第五信号,前述第四时间单位是上述TDD上下行配置中的灵活时间单位,和/或,前述第五时间单位是上述TDD上下行配置中的灵活时间单位。
根据前述实施例中,网络设备通过指示转发器使用灵活时间单位与网络设备进行上行和/或下行通信,有助于减低对现有标准的影响,加速标准化进程;以及减少网络设备升级开发的时间,加速在网络中部署转发器的速度。
以上各个实施例仅对本申请实施例进行了示例性说明,但本申请不限于此,还可以在以上各个实施例的基础上进行适当的变型。例如,可以单独使用上述各个实施例,也可以将以上各个实施例中的一种或多种结合起来。
