Description

一种天线参数调整的方法以及相关装置 技术领域
本申请涉及通信领域，尤其涉及一种天线参数调整的方法以及相关装置。
背景技术
为了应对无线宽带技术的挑战，保持第三代合作伙伴计划(3rd generation partnership project，3GPP)网络的领先优势，3GPP标准组在2016年底制定了下一代移动通信系统(next generation system)网络架构，称为第五代(5rd generation，5G)网络架构，还称为5g新通信协议(5g new radio，5g NR或NR)。该架构不但支持3GPP标准组定义的无线技术接入5G核心网络(5G core network)，而且支持非3GPP(non-3GPP)接入技术接入5G核心网络，比如支持固网接入5G核心网络。
终端设备(user equipment，UE)在发送信号的时候，在基带生成基带信号后，会经过射频链路生成射频信号，然后经过天线发送出去。终端设备在接收信号的时候，也会有对应的射频接收链路。在NR中，网络设备和UE都可以通过多输入多输出(multiple input multiple output，MIMO)技术提升通信性能，又称为多天线技术。为了更好的调度数据传输，NR中会对传输使用的信道状态进行估计，并且网络设备根据信道估计结果可以选择合适的传输参数，该过程称为信道估计(channel estimation)。在NR中，UE可以使用信道状态信息参考信号(channel state information reference signal，CSI-RS)和探测参考信号(sounding reference signal，SRS)进行信道估计。MIMO技术的引入，虽然提升了通信性能，但是终端设备使用多个天线进行传输，又会引起功耗大的问题。现在提出了一种降低终端设备功耗的方案：减少终端设备用于传输数据的天线数，或称为调整天线参数，以达到减少终端设备功耗的目的。
由于网络设备在调整终端设备的天线参数后，均需要进行信道估计。网络设备需要根据信道估计结果选择合适的传输参数以保证数据传输的成功率。现有技术中，出于降低终端设备功耗的目的，终端设备可以执行调整天线参数(即关闭部分天线)的操作已达到降低功耗的目的，此时网络设备仍使用原有天线参数条件下信道估计结果进行数据传输，与当前天线参数条件下信道估计结果不匹配，增加了数据传输的失败概率。

终端设备确定终端设备中是否还配置有发射天线端口数小于或等于N的第三上行参考信号资源。若配置第三上行参考信号资源，则网络设备接收终端设备使用第三上行参考信号资源发送的上行参考信号；若没有配置第三上行参考信号资源，则网络设备接收终端设备使用第一上行参考信号资源发送的上行参考信号，其中终端设备使用第一上行参考信号资源中任意M个中的N个发射天线端口发送上行参考信号，或者终端设备关闭第一上行参考信号资源中的大于N的发射天线端口后，网络设备接收终端设备使用第一上行参考信号资源发送的上行参考信号，具体的，可以关闭端口号较大的端口，保留端口号较小的端口；或者关闭端口号较小的端口，保留端口号较大的端口。

具体实施方式
本申请实施例提供了一种天线参数调整的方法以及相关装置，网络设备通过第一信令指示终端设备调整天线参数，该第一信令还用于指示终端设备进行信道估计，以便网络设备及时获取信道估计结果，根据该信道估计结果进行数据传输，降低传输失败的概率。
在介绍本实施例之前，首先介绍本实施例中可能出现的几个概念。应理解的是，以下的概念解释可能会因为本实施例的具体情况有所限制，但并不代表本申请仅能局限于该具体情况，以下概念的解释伴随不同实施例的具体情况可能也会存在差异。
图1为本申请实施例中的无线通信网络拓扑示意图。如图1所示，无线通信网络100包括网络设备102～106和终端设备108～122，其中，网络设备102～106彼此之间可通过回程(backhaul)链路(如网络设备102～106彼此之间的直线所示)进行通信，该回程链路可以是有线回程链路(例如光纤、铜缆)，也可以是无线回程链路(例如微波)。终端设备108～122可通过无线链路(如网络设备102～106与终端设备108～122之间的折线所示)与对应的网络设备102～106通信，网络设备102～106还可以称为基站。
网络设备102～106通常作为接入设备来为通常作为用户设备的终端设备108～122提供无线接入服务。具体来说，每个网络设备都对应一个服务覆盖区域(又可称为蜂窝，如图1中各椭圆区域所示)，进入该区域的终端设备可通过无线信号与网络设备通信，以此来接受网络设备提供的无线接入服务。网络设备的服务覆盖区域之间可能存在交叠，处于交叠区域内的终端设备可收到来自多个网络设备的无线信号，因此这些网络设备可以进行相互协同，以此来为该终端设备提供服务。例如，多个网络设备可以采用多点协作(coordinated multipoint，CoMP)技术为处于上述交叠区域的终端设备提供服务。例如，如图1所示，网络设备102与网络设备104的服务覆盖区域存在交叠，终端设备112便处于该交叠区域 之内，因此终端设备112可以收到来自网络设备102和网络设备104的无线信号，网络设备102和网络设备104可以进行相互协同，来为终端设备112提供服务。又例如，如图1所示，网络设备102、网络设备104和网络设备106的服务覆盖区域存在一个共同的交叠区域，终端设备120便处于该交叠区域之内，因此终端设备120可以收到来自网络设备102、104和106的无线信号，网络设备102、104和106可以进行相互协同，来为终端设备120提供服务。
依赖于所使用的无线通信技术，网络设备又可称为节点B(NodeB)，演进节点B(evolved nodeb,eNodeB)以及接入点(access point，AP)等。此外，根据所提供的服务覆盖区域的大小，网络设备又可分为用于提供宏蜂窝(macro cell)的宏网络设备、用于提供微蜂窝(pico cell)的微网络设备和用于提供毫微微蜂窝(femto cell)的毫微微网络设备等。随着无线通信技术的不断演进，未来的网络设备也可以采用其他的名称。
终端设备108～122可以是具备无线通信功能的各种无线通信设备，例如但不限于移动蜂窝电话、无绳电话、个人数字助理(personal digital assistant，PDA)、智能电话、笔记本电脑、平板电脑、无线数据卡、无线调制解调器(modulator demodulator，Modem)或者可穿戴设备如智能手表等。随着物联网(internet of things，IOT)技术和车联网(vehicle-to-everything，V2X)技术的兴起，越来越多之前不具备通信功能的设备，例如但不限于，家用电器、交通工具、工具设备、服务设备和服务设施，开始通过配置无线通信单元来获得无线通信功能，从而可以接入无线通信网络，接受远程控制。此类设备因配置有无线通信单元而具备无线通信功能，因此也属于无线通信设备的范畴。此外，终端设备108～122还可以称为移动台、移动设备、移动终端、无线终端、手持设备、客户端等。
网络设备102～106，和终端设备108～122均可配置有多根天线，以支持多入多出(multiple input multiple output，MIMO)技术。进一步的说，网络设备102～106和终端设备108～122既可以支持单用户MIMO(single-user mimo，SU-MIMO)技术，也可以支持多用户MIMO(multi-user mimo，MU-MIMO)，其中MU-MIMO可以基于空分多址(space division multiple access，SDMA)技术来实现。由于配置有多根天线，网络设备102～106和终端设备108～122还可灵活支持单入单出(single input single output，SISO)技术、单入多出(single input multiple output，SIMO)和多入单出(multiple input single output，MISO)技术，以实现各种分集(例如但不限于发射分集和接收分集)和复用技术，其中分集技术可以包括例如但不限于发射分集(transmit diversity，TD)技术和接收分集(receive diversity，RD)技术，复用技术可以是空间复用(spatial multiplexing)技术。而且上述各种技术还可以包括多种实现方案，例如发射分集技术可以包括，例如但不限于，空时发射分集(space-timetransmit diversity，STTD)、空频发射分集(space-frequency transmit diversity，SFTD)、时间切换发射分集(time switched transmit diversity，TSTD)、频率切换发射分集(frequency switch transmit diversity，FSTD)、正交发射分集(orthogonal transmit diversity，OTD)、循环延迟分集(cyclic delay diversity，CDD)等分集方式，以及上述各种分集方式经过衍生、演进以及组合后获得的分集方式。例如，目前长期演进(long term evolution，LTE)标准便采用了空时块编码(space time block coding，STBC)、空频块编码(space frequency block coding，SFBC)和CDD等发射分集方式。上文以举例的方式对发射分集进行了的概括性的描述。本领域技术人员应当明白，除上述实例外，发射分集还包括其他多种实现方式。因此，上述介绍不应理解为对本发明技术方案的限制，本发明技术方案应理解为适用于各种可能的发射分集方案。
此外，网络设备102～106和终端设备108～122可采用各种无线通信技术进行通信，例如但不限于，时分多址(time division multiple access，TDMA)技术、频分多址(frequency division multiple  access，FDMA)技术、码分多址(code division multiple access，CDMA)技术、时分同步码分多址(time division-synchronous code division multiple access，TD-SCDMA)、正交频分多址(orthogonal fdma，OFDMA)技术、单载波频分多址(single carrier fdma，SC-FDMA)技术、空分多址(space division multiple access，SDMA)技术以及这些技术的演进及衍生技术等。上述无线通信技术作为无线接入技术(radio access technology，RAT)被众多无线通信标准所采纳，从而构建出了在今天广为人们所熟知的各种无线通信系统(或者网络)，包括但不限于由802.22系列标准中定义的WiFi、全球互通微波存取(worldwide interoperability for microwave access，WiMAX)、长期演进(long term evolution，LTE)、LTE升级版(lte advanced，LTE-A)以及这些无线通信系统的演进系统，例如5G新空口技术(5G new radio，5G NR)等。如无特别说明，本发明实施例提供的技术方案可应用于上述各种无线通信技术和无线通信系统。此外，术语“系统”和“网络”可以相互替换。
应注意，图1所示的无线通信网络100仅用于举例，并非用于限制本发明的技术方案。本领域的技术人员应当明白，在具体实现过程中，无线通信网络100还可能包括其他设备，同时也可根据具体需要来配置网络设备和终端设备的数量。
下面对MIMO技术进行说明。多天线技术，即多输入多输出(multiple-input multiple-output，MIMO)技术指在发射端和接收端分别使用多个发射天线和接收天线，使信号通过发射端与接收端的多个天线传送和接收，从而改善通信质量。它能充分利用空间资源，通过多个天线实现多发多收，在不增加频谱资源和天线发射功率的情况下，可以成倍的提高系统信道容量，显示出明显的优势、被视为下一代移动通信的核心技术。在新无线电通信(new radio，NR)中，网络设备与终端设备都可以通过MIMO技术提升通信性能。
为了便于理解终端设备与网络设备之间信号交互的过程，请参见图2，图2为本申请实施例中射频链路示意图。以终端设备向网络设备发送信号为例，终端设备在向网络设备发送信号，首先在基带生成基带信号后，会经过射频链路处理，其中，射频链路一般包含三级射频集成电路、功率放大器以及双工器/滤波器，基带信号经过处理后生成射频信号，然后射频信号经过天线发送出去。终端设备接收信号的过程与发送信号的过程类似，此处不再赘述。
在现有标准中，网络设备并不明确知道终端设备有多少射频链路，而是采用天线端口这一术语进行描述。比如当终端设备实际有两个发射射频链路的时候，该终端设备最多支持同时使用2个天线端口与网络设备进行上行通信。如果终端设备使用2个天线端口与网络设备进行通信，则在实际上每个射频链路会对应一个天线端口。如果终端设备使用1个天线端口与网络设备进行通信，终端设备可以使用任意一个上行射频链路对应到这个天线端口，也可以同时使用两个射频链路模拟成一个天线端口，这取决于终端设备的具体实现，对网络设备而言是透明的。网络设备只需要调度终端设备在哪个或哪些天线端口上发送数据即可。下面为了简化描述，将一个终端设备支持一个发射射频链路(transmit，T)，两个接收射频链路(receive，R)称为1T2R。以此类推，一个终端设备支持2个发射射频链路和4个接收射频链路称为2T4R。通常情况下，终端设备中的接收射频链路数量会大于或等于发射射频链路数量，并且每一个接收射频链路与一根天线(即电磁波的辐射单元)连接，因此1T2R也可以理解为该终端设备中有一个发射射频链路与两根天线。以此类推，2T4R也可以理解为该终端设备中有两个发射射频链路与四根天线。该天线具有发射电磁波与接收电磁波的能力，因此本申请实施例中的天线、发射天线以及接收天线可视为同一事物。
终端设备通过上行信道向网络设备发送附加的(additional)上行信号，终端设备通过下行信道接收网络设备发送的附加的下行信号，为了保证数据传输的质量，NR中会对信道状态进行估计，这个过 程称为信道估计，网络设备根据信道估计结果选择合适的传输参数，该传输参数包括调制和编码方案索引值(modulation and coding scheme，MCS)，预编码矩阵(precoding matrix，PM)等。
在NR中，终端设备具体可以向网络设备发送探测参考信号(sounding reference signal，SRS)进行上行信道的信道估计。终端设备通过接收网络设备发送的信道状态信息参考信号(channel state information reference signal，CSI-RS)，并向网络设备发送信道状态信息报告(channel state information report，CSI report)进行下行信道的信道估计。或者在时分双工(time division duplexing，TDD)系统中终端设备向网络设备发送探测参考信号，网络设备通过上下行信道的互易性进行下行信道的信道估计。需要说明的是，终端设备还可以使用其它的参考信号进行信道估计，当使用其它的下行参考信号进行信道估计时，终端设备向网络设备发送对应的下行参考信号报告消息以完成信道估计，此处仅以SRS与CSI-RS为例进行说明，不作限定。下面对SRS与CSI-RS分别进行描述。
(1)、CSI-RS。
网络设备向终端设备配置CSI-RS资源，当网络设备需要获知终端设备下行信道的信道状态时，网络设备通过下行信道使用配置的CSI-RS资源向终端设备发送CSI-RS。终端设备接收该CSI-RS，并对该CSI-RS进行处理，以对当前下行信道进行状态估计。终端设备处理结束后生成信道状态信息报告(CSI-RS report)，其中，信道状态信息报告中包括下列多种信息中的一种或多种，例如：秩指示(rank indication，RI)、预编码矩阵指示(precoding matrix indication，PMI)、信道质量指示(channel quality indication，CQI)、信道状态信息参考信号资源指示(CSI-RS resource indicator，CRI)、同步信号/广播信道块资源指示(synchronous signal/physical broadcast channel block resource indicator，SS/PBCH BRI)、层指示(layer indicator，LI)以及层1参考信号接收功率(layer 1reference signal revceived power，L1-RSRP)，需要说明的是，该层1参考信号接收功率所指的层1为物理层。
终端设备向网络设备发送该信道状态信息报告。以使得网络设备获知当前的下行信道的信道估计结果并调整传输参数。
其中，CSI-RS资源可分为下列三种：周期性CSI-RS资源、半持续性CSI-RS资源以及非周期性CSI-RS资源。下面分别进行描述。
周期性CSI-RS资源：网络设备通过RRC信令向终端设备配置周期性CSI-RS资源。当配置完成后，网络设备就会周期性发送CSI-RS，终端设备可以周期性接收CSI-RS。
半持续性CSI-RS资源：网络设备通过RRC信令向终端设备配置半持续性CSI-RS资源，此时网络设备不会立刻发送CSI-RS。网络设备还需要向终端设备发送用以激活(activate)该半持续性CSI-RS资源的DCI后，网络设备才会周期性发送该CSI-RS。当网络设备不再发送该CSI-RS时，网络设备还可以通过向终端设备发送去激活(deactivate)该半持续性CSI-RS资源的DCI，以去激活的终端设备中的该半持续性CSI-RS资源。
非周期性CSI-RS资源：网络设备通过RRC信令向终端设备配置非周期性CSI-RS资源，但是不会立刻发送CSI-RS。网络设备还需要向终端设备发送用以触发(trigger)该非周期性CSI-RS资源的DCI后，网络设备才会发送一次该CSI-RS。需要说明的是，网络设备在每一次发送CSI-RS之前，都需要向终端设备发送用以触发该非周期性CSI-RS资源的DCI。
(2)、SRS。
网络设备向终端设备配置SRS资源，终端设备使用SRS资源向网络设备发送SRS。网络设备接收该SRS后对其进行分析测量，以获知当前的上行信道的信道估计结果并调整传输参数。
其中，SRS资源可分为下列两种：周期性SRS资源以及非周期性SRS资源。下面分别进行描述。
周期性SRS资源：网络设备通过RRC信令向终端设备配置周期性SRS资源。当配置完成后，终端设备就会周期性发送SRS，网络设备可以周期性接收SRS。
非周期性SRS资源：网络设备通过RRC信令向终端设备配置非周期性SRS资源，但是终端设备不会立刻发送SRS。网络设备还需要向终端设备发送用以触发(trigger)该非周期性SRS资源的DCI后，终端设备才会发送一次该SRS。需要说明的是，终端设备在每一次发送SRS之前，网络设备都需要向终端设备发送用以触发该非周期性SRS资源的DCI。
需要说明的是，在时分双工(time division duplexing，TDD)系统中，由于终端设备上行传输与下行传输使用相同的频域资源，因此可以认为上行信道与下行信道的信道状态非常相似，该信道状态包括有功率衰减、相位移动等，这个特性称为信道互异性。利用TDD系统中的信道互异性，仅通过配置SRS资源并进行信道估计，即可获得上行信道与下行信道的信道估计结果。
网络设备向终端设备配置的SRS资源配置信息中，还指示了终端设备向网络设备发送SRS时所采用的发送天线端口数，终端设备按照SRS资源所指示的发送天线端口向网络设备发送SRS。下面对上述过程进行详细描述。请参阅图3，图3为本申请实施例中终端设备发射天线示意图。图3中该终端设备中配置有一个发射射频电路与四根发射天线，该发射射频电路可以与任意一根发射天线连接以向网络设备发送电磁波。当终端设备使用不同的发射天线向网络设备发送电磁波时，不同的发射天线与网络设备之间的信道状态有可能是不同的，这种情况出现的原因是例如：当用户握持终端设备时，有可能遮挡住某一根发射天线，造成该发射天线发送至网络设备的电磁波衰减较大，影响通信质量。因此为了提升通信质量，引入了天线轮发机制，具体为：终端设备中射频电路在不同的发射天线之间进行切换，终端设备连续发送多个SRS，这些SRS通过不同的发射天线向网络设备发送。网络设备接收到这些SRS之后，可根据SRS的信号质量，确定哪一根发射天线与网络设备之间的信道状态较好，网络设备在调度终端设备接收下行数据时，将信道状态较好的天线优先级升高，以使得终端设备优先使用信道状态较好的天线接收下行数据。
由于不同的终端设备硬件配置不相同，基于硬件配置，终端设备的天线轮发能力也是不一样的。在NR中规定SRS天线轮发能力如下：1T2R、1T4R、2T4R、1T4R-2T4R、1T1R、2T2R或4T4T等。下面举例说明，1T2R为终端设备中有一个发射射频链路与两根天线，此时终端设备每次可以使用单端口发送一个SRS，完成轮发需要发送两次，即第一次发送SRS使用第一射频链路与第一天线，第二次发送SRS使用第一射频链路与第二天线。2T4R为终端设备有两个发射射频链路与四根天线，此时终端设备每次可以使用双端口发送一个SRS，完成轮发需要发送两次，即第一次发送SRS使用第一射频链路与第二射频拦路以及第一天线与第二天线，第二次发送SRS使用第一射频链路与第二射频链路以及第三天线与第四天线。1T4R-2T4R为该终端设备既支持1T4R的SRS天线轮发也支持2T4R的SRS天线轮发。
通过引入MIMO技术以及信道估计，终端设备在多天线的情况下也可以保障与网络设备的通信质量，同时，网络设备与终端设备的天线数越多，通信性能越好。但是随着天线数的增加，终端设备的功耗也随之增大，同时大功耗带来了发热量大的问题，发热量大影响终端设备的性能。因此出于降低终端设备功耗的考虑，现有方案中可通过减少天线数即调整天线参数，以达到降低功耗的目的。但是调整天线参数后，终端设备可能会遇到两个问题，第一个问题是调整天线参数前得到的信道估计结果，与调整天线参数后实际传输数据所使用的信道不匹配。第二个问题是调整天线参数后实际可用天线端口数，与SRS资源所指示的发送SRS时所采用的发送天线端口数不匹配，该SRS资源为调整天线参数前所配置的。下面对这两个问题举例说明。
第一个问题：终端设备为1T4R为例，当终端设备在调整天线参数前，向网络设备上报终端设备可 以使用四根天线接收CSI-RS。因此，在调整天线参数前，网络设备获取到的信道估计结果是基于四根天线建立的信道。当终端设备调整天线参数后，例如关闭其中的任意两根天线，此时终端设备仅可以使用两根天线接收CSI-RS，而网络设备仍然依照四根天线所支持的4层(layer)数据进行传输调度，因此，终端设备无法正确接收网络设备发送的数据，一根天线所对应的子信道内传输的数据称为1层数据，该1层数据与其它子信道内传输的数据互不干扰，这里的4层数据为四根天线所对应的四个子信道内传输的数据。
另外，在调整天线参数前，终端设备可以采用分集增益，从而支持较高的调制与编码策略(modulation and coding scheme，MCS)等级。分集增益为终端设备使用一根以上的天线接收相同的一份数据，以提升数据传输的可靠性。例如1T4R的终端设备，使用第一天线与第二天线接收第一数据，第三天线与第四天线接收第二数据，此时终端设备相当于使用多根天线传输相同的一份数据。当终端设备采用分集传输时，调整天线参数后，即使网络设备不是按照4层数据进行传输调度，此时网络设备调度数据所使用的信道估计结果，还是终端设备使用四根天线时的信道估计结果，与当前两根天线所对应的两个子信道不匹配，增加了传输失败的概率。
当终端设备向网络设备发送SRS以完成上行信道估计时，终端设备关闭了哪些天线对于网络设备来说是未知的，因此，网络设备并不知道终端设备关闭的天线所对应的端口，网络设备同样无法知道当前的信道状态。
第二个问题：终端设备为1T2R为例，调整天线参数之前，终端设备向网络设备上报其上行发送能力为2天线，网络设备获知终端设备的上行发送能力后为终端设备配置2端口和/或1端口的SRS资源，以使得终端设备根据该SRS资源，向网络设备通过2端口和/或1端口发送SRS。调整天线参数后，终端设备关闭其中任意一根天线，此时终端设备无法使用2端口发送SRS。
基于上述两个问题，本申请实施例提出了一种方案，在终端设备调整天线参数后，提升终端设备与网络设备之间数据传输的成功率，以及在终端设备调整天线参数后，解决终端设备如何选择天线端口用以发送SRS的问题。
下面结合附图对本申请实施例进行描述，请参阅图4，图4为本申请实施例中天线参数调整的方法的一种实施例示意图，本申请实施例提供的一种天线参数调整的方法包括；
401、网络设备向终端设备发送第一配置信息。
本实施例中，网络设备向终端设备发送第一配置信息，该第一配置信息用于在终端设备中配置参考信号资源。当第一配置信息在终端设备中配置的是上行参考信号资源时，终端设备可以使用配置的上行参考信号资源向网络设备发送附加的上行参考信号。当第一配置信息在终端设备中配置的是下行参考信号资源时，终端设备可以使用配置的下行参考信号资源接受网络设备发送附加的下行参考信号。需要说明的是，网络设备向终端设备发送的第一配置信息，还可以用于在终端设备中同时配置上行参考信号资源与下行参考信号资源，以使得终端设备可以向网络设备发送附加的上行参考信号，也可以接收网络设备发送的附加的下行参考信号。附加的上行参考信号用于上行信道估计，附加的下行参考信号用于下行信道估计。
其中，当第一配置信息配置的上行参考信号资源为SRS资源时，终端设备可以使用该SRS资源向网络设备发送SRS。当第一配置信息配置的是下行参考信号资源为CSI-RS资源时，终端设备可以使用该CSI-RS资源接收网络设备发送的CSI-RS。
402、网络设备向终端设备发送第一信令。
本实施例中，网络设备向终端设备发送第一信令，第一信令中包含第一指示信息和第二指示信息， 第一指示信息用于指示终端设备调整天线参数，第二指示信息用于指示终端设备发送或接收附加的参考信号，附加的参考信号用于在天线参数调整后进行信道估计。
具体的，第一指示信息指示终端设备调整接收天线参数，第二指示信息指示终端设备接收附加的下行参考信号；或者第一指示信息指示终端设备调整发射天线参数，第二指示信息指示终端设备发送附加的上行参考信号；或者第一指示信息指示终端设备调整接收天线参数且调整发射天线参数，第二指示信息指示终端设备接收附加的下行参考信号且发送附加的上行参考信号。
当第一指示信息指示终端设备调整接收天线参数，第二指示信息指示终端设备接收附加的下行参考信号时，执行完步骤403后，执行步骤405，不执行步骤404；当第一指示信息指示终端设备调整发射天线参数，第二指示信息指示终端设备发送附加的上行参考信号时，执行完步骤403后，执行步骤404，不执行步骤405；当第一指示信息指示终端设备调整接收天线参数且调整发射天线参数，第二指示信息指示终端设备接收附加的下行参考信号且发送附加的上行参考信号时，执行完步骤403后，需要执行步骤404以及步骤405，此时不对步骤404以及步骤405的执行顺序进行限定。例如：既可以先执行步骤404，再执行步骤405。也可以先执行步骤405，再执行步骤404。还可以同时执行步骤404以及步骤405。
当第一信令中仅包含第一指示信息，不包含第二指示信息时，执行步骤403后不再执行步骤404和/或步骤405。
第一信令可以承载于下行控制信息(downlink control information，DCI)、参考信号(reference signals，RS)、媒体访问控制地址控制元素(media access control control element，MAC CE)或无线资源控制(radio resource control，RRC)中的任意一种。
需要说明的是，当第一信令承载于MAC CE或RRC中时，在调整天线参数之前，终端设备还需要向网络设备发送混合自动重传请求确认信息(hybrid automatic repeat request-acknowledge，HARQ-ACK)，网络设备根据该HARQ-ACK会向终端设备反馈一个HARQ-ACK的确认信息。当终端设备接收到该HARQ-ACK的确认信息后，终端设备再根据第一指示信息调整天线参数。
403、终端设备根据第一信令调整天线参数。
本实施例中，终端设备接收到第一信令后，根据第一指示信息调整天线参数。当第一信令中的第一指示信息为指示调整接收天线参数时，终端设备对应的开启或关闭接收天线端口。当第一信令中的第一指示信息为指示调整发射天线参数时，终端设备对应的开启或关闭发射天线端口。
第一指示信息用于指示调整发射天线参数存在多种方案，下面进行举例描述。
例如：
一、当第一指示信息具体用于指示终端设备的最大发射天线数为N，其中，N为正整数，在步骤402之前，终端设备中若配置的第一上行参考信号资源，其附加的上行参考信号的发射天线端口数为M，其中，M为正整数，M大于N。若终端设备还配置有发射天线端口数为K的第二上行参考信号资源时，K为正整数，K小于M，终端设备使用第二上行参考信号资源发送上行参考信号且不使用第一上行参考信号资源发送上行信号。
二、当第一指示信息具体用于指示终端设备的最大发射天线数为N，其中，N为正整数，在步骤402之前，终端设备中仅配置的第一上行参考信号资源，其附加的上行参考信号的发射天线端口数为M，其中，M为正整数，M大于N。此时终端设备使用第一上行参考信号资源中M个中的任意N个发射天线端口数发送上行信号。
三、当第一指示信息具体用于指示终端设备的最大发射天线数为N，其中，N为正整数，在步骤402之前，终端设备中若配置的第一上行参考信号资源，其附加的上行参考信号的发射天线端口数为M，其 中，M为正整数，M大于N。则终端设备确定是否还配置有发射天线端口数小于或等于N的第三上行参考信号资源，若配置第三上行参考信号资源，则终端设备使用第三上行参考信号资源发送附加的上行参考信号；若没有配置第三上行参考信号资源，则终端设备使用第一上行参考信号资源发送附加的上行参考信号，其中终端设备使用第一上行参考信号资源中任意M个中的N个发射天线端口发送附加的上行参考信号，或者终端设备关闭第一上行参考信号资源中的大于N的发射天线端口后，使用第一上行参考信号资源发送附加的上行参考信号。
404、终端设备向网络设备发送附加的参考信号。
本实施例中，终端设备根据第一指示信息在调整了发射天线参数后，终端设备向网络设备发送附加的上行参考信号，例如SRS。根据第一信令承载的不同，终端设备向网络设备发送附加的上行参考信号所使用的时域资源不一致。
例如：当第一信令承载于DCI或RS中，终端设备在接收到第一信令后，即可向网络设备发送附加的上行参考信号，此时发送附加的上行参考信号所使用的时域资源称为第一时域资源。
当第一信令承载于MAC CE或RRC中，终端设备还需要接收HARQ-ACK的确认信息，该HARQ-ACK的确认信息为网络设备根据终端设备发送的HARQ-ACK生成。在终端设备接收HARQ-ACK的确认信息之后，终端设备向网络设备发送附加的上行参考信号，此时发送附加的上行参考信号所使用的时域资源称为第二时域资源。
405、网络设备向终端设备发送附加的参考信号。
本实施例中，终端设备根据第一指示信息在调整了接收天线参数后，网络设备向终端设备发送附加的下行参考信号，例如CSI-RS。终端设备在接收到附加的下行参考信号之后，终端设备根据附加的下行参考信号确定下行参考信号报告消息。终端设备通过物理上行控制信道(physical uplink control channel，PUCCH)或物理上行共享信道(physical uplink shared channel，PUSCH)向网络设备发送下行参考信号报告消息，其中，下行参考信号报告消息包含下行信道估计的结果，当附加的下行参考信号为CSI-RS时，该下行参考信号报告消息为信道状态信息报告(CSI-RS report)。
具体的，终端设备接收附加的下行参考信号之后，在第一个PUCCH或第一个PUSCH使用的时频资源中，通过第一个PUCCH或第一个PUSCH向网络设备发送下行参考信号报告消息；或者，终端设备接收下行参考信号之后，预先配置的PUCCH或预先配置的PUSCH的时频资源中，通过预先配置的PUCCH或预先配置的PUSCH向网络设备发送下行参考信号报告消息，该预先配置的PUCCH或该预先配置的PUSCH为网络设备向终端设备预先配置的信道；或者，第一信令还用于指示PUCCH或PUSCH的资源，此时第一信令中包含PUCCH或PUSCH的资源的索引值(index)，终端设备接收下行参考信号之后，通过第一信令所指示的PUCCH或所指示的PUSCH的资源，向网络设备发送下行参考信号报告消息。
本申请实施例中，网络设备通过第一信令指示终端设备调整天线参数，该第一信令还用于指示终端设备进行信道估计，以便网络设备及时获取信道估计结果，根据该信道估计结果进行数据传输，降低传输失败的概率。
为了使本技术领域的人员更好地理解本申请技术方案，下面将结合本申请实施例中的附图，对本申请技术方案做进一步的说明。为了便于理解，本申请实施例中附加的上行参考信号以SRS为例，附加的下行参考信号以CSI-RS为例，需要说明的是，附加的上行参考信号以及附加的下行参考信号还可以通过其它的参考信号、数据或控制指令等载体实现相同的技术效果，此处不作限定。由第一信令触发的终端设备接收CSI-RS以及终端设备向网络设备发送CSI-RS报告信息的过程属于非周期性CSI-RS传输。由第一信令触发的终端设备向网络设备发送SRS的过程属于非周期性SRS传输。
请参阅图5a，图5a为本申请实施例中天线参数调整的方法的一种流程示意图。
本实施例中，图5a所示意的终端设备中配置有4根接收天线。横坐标的单位为时间，图中的方块为当前动作所使用的时域资源。终端设备中预先配置周期性或半持续性CSI-RS资源，如图所示，从左往右数，第1方块(垂直网格填充)、第2方块(垂直网格填充)、第5方块(垂直网格填充)以及第6方块(垂直网格填充)为终端设备使用周期性或半持续性CSI-RS资源接收CSI-RS所使用的时域资源。从左往右数，第3方块(横线填充)为终端设备接收第一信令所使用的时域资源，该第一信令中的第一指示信息用于指示终端设备将接收天线数从4根接收天线，调整为2根接收天线，即关闭其中任意2根接收天线。终端设备根据该第一指示信息调整天线参数，在图5a中纵向实线所指示的时刻，终端设备完成从4根接收天线调整至2根接收天线的调整天线参数过程。在从左往右数第4方块(竖线填充)所指示的时域资源中，终端设备根据该第一信令中的第二指示信息，使用预先配置的非周期性CSI-RS资源，接收网络设备发送的CSI-RS。终端设备根据接收到的该CSI-RS估计当前信道状态。终端设备完成信道估计后，向网络设备发送CSI报告消息，发送该CSI报告消息所使用的时域资源位置，具体有下面这几种情况：
具体的，终端设备接收非周期性CSI-RS之后，使用第一个PUCCH或第一个PUSCH的时频资源，通过第一个PUCCH或第一个PUSCH向网络设备发送CSI报告消息；或者，终端设备接收非周期性CSI-RS之后，使用网络设备预先配置的PUCCH或预先配置的PUSCH的时频资源，通过预先配置的PUCCH或预先配置的PUSCH向网络设备发送CSI报告消息；或者，第一信令还用于指示PUCCH或PUSCH的资源，此时第一信令中包含PUCCH或PUSCH的资源的索引值(index)，终端设备接收非周期性CSI-RS之后，通过第一信令所指示的PUCCH或所指示的PUSCH的资源，向网络设备发送CSI报告消息。
本申请实施例中，现有技术中，终端设备在调整天线参数后的第一个周期性CSI-RS或者已经被激活的半持续性CSI-RS(即图5a中从左向右数第5方块)所使用的时域资源内才能够接收CSI-RS并测量信道，这样会造成比较大的延迟。而在纵向实线指示的调整天线参数所使用的时刻至第5方块所使用的时域资源之间，网络设备只能利用终端设备在调整天线参数之前，使用4接收天线得到的信道估计结果进行传输调度，与终端设备当前信道不匹配(2接收天线)，可能导致传输失败。而本申请技术方案引入的，由第一信令触发的非周期性CSI-RS，使得终端设备可以快速估计信道，并且进行反馈。这样网络设备就可以快速获取信道状态，以便于调整传输参数。
请参阅图5b，图5b为本申请实施例中天线参数调整的方法的另一种流程示意图。
本实施例中，图5b所示意的终端设备中配置有2根发射天线。横坐标的单位为时间，图中的方块为当前动作所使用的时域资源。终端设备中预先配置周期性SRS资源，如图所示，从左往右数，第1方块(垂直网格填充)、第2方块(垂直网格填充)、第5方块(垂直网格填充)以及第6方块(垂直网格填充)为终端设备使用周期性发送SRS所使用的时域资源。从左往右数，第3方块(横线填充)为终端设备接收第一信令所使用的时域资源，该第一信令中的第一指示信息用于指示终端设备将发射天线数从2根发射天线，调整为1根发射天线，即关闭其中任意1根发射天线。终端设备根据该第一指示信息调整天线参数，在图5b中纵向实线所指示的时刻，终端设备完成从2根发射天线调整至1根发射天线的调整天线参数过程。在从左往右数第4方块(竖线填充)所指示的时域资源中，终端设备根据该第一信令中的第二指示信息，使用预先配置的非周期性SRS资源，向网络设备发送SRS。网络设备根据接收到的该SRS估计当前信道状态。
本申请实施例中，现有技术中，终端设备在调整天线参数后的第一个周期性SRS(即图5b中从左向右数第5方块)所使用的时域资源内才能够发送SRS并测量信道，这样会造成比较大的延迟。而在纵 向实线指示的调整天线参数所使用的时刻至第5方块所使用的时域资源之间，网络设备只能利用终端设备在调整天线参数之前，使用2发射天线得到的信道估计结果进行传输调度，与终端设备当前信道不匹配(1发射天线)，可能导致传输失败。而本申请技术方案引入的，由第一信令触发的非周期性SRS，使得终端设备可以快速发送SRS，这样网络设备就可以快速获取信道状态，以便于调整传输参数。
上文中提到，第一信令可以承载于下行控制信息(downlink control information，DCI)、参考信号(reference signals，RS)、媒体访问控制地址控制元素(media access control control element，MAC CE)或无线资源控制(radio resource control，RRC)中的任意一种。对于第一信令所承载的信令不同，其触发非周期性CSI-RS传输或非周期性SRS传输所使用的时域资源不同，下面结合附图详细说明。
请参阅图6a以及图6b，图6a为本申请实施例中天线参数调整的方法的另一种流程示意图，图6b为本申请实施例中天线参数调整的方法的另一种流程示意图。本实施例中，当第一信令承载于DCI或RS这类物理层信令时，终端设备进行非周期性CSI-RS传输和/或非周期性SRS传输所使用的时域资源，均在终端设备接收第一信令之后，并且在终端设备调整完天线参数之后，该时域资源称为第一时域资源。
当第一信令承载于MAC CE或RRC这类高层信令时，请参阅图7a以及图7b，图7a为本申请实施例中天线参数调整的方法的另一种流程示意图，图7b为本申请实施例中天线参数调整的方法的另一种流程示意图。
本实施例中，由于第一信令承载于MAC CE或RRC这类高层信令，网络设备通过物理下行共享信道(physical downlink shared channel，PDSCH)向终端设备发送。终端设备首先需要在物理层中对PDSCH进行解码。当终端设备对PDSCH解码成功后，终端设备向网络设备发送HARQ-ACK，用以通知网络设备终端设备对PDSCH解码成功。网络设备对接收到HARQ-ACK后，向终端设备反馈HARQ-ACK的确认信息，该HARQ-ACK的确认信息还可以称为HARQ反馈。终端设备接收到HARQ-ACK的确认信息之后，还需要对PDSCH解码成功后获得的数据包传递至终端设备的高层中做进一步解析。进一步解析成功后终端设备才可以获知该数据包中第一信令的正确内容。终端设备进行非周期性CSI-RS传输和/或非周期性SRS传输所使用的时域资源，均在终端设备接收HARQ反馈之后，并且在终端设备调整完天线参数之后，该时域资源称为第二时域资源。
因此如图7a以及图7b所示，图中从左向右数第3方块(竖线填充)所对应的时域资源，为终端设备进行非周期性CSI-RS传输和/或非周期性SRS传输所使用的时域资源。第2方块(菱形网格填充)为终端设备接收HARQ-ACK的确认信息所使用的时域资源。第3方块与第2方块之间的时间间隔称为第一时间间隔。当第一信令承载于MAC CE中时，该第一时间间隔可以为3毫秒。需要说明的是，该第一时间间隔根据终端设备实际解析能力、终端设备调整天线参数的速率以及第一信令所承载的信令类型决定，此处不作限定。
本申请实施例中，当第一信令承载于DCI或RS这类物理层信令时，第一信令所触发的非周期性CSI-RS传输和/或非周期性SRS传输所使用的第一时域资源，在终端设备接收第一信令所使用的时域资源之后。当第一信令承载于MAC CE或RRC这类高层信令时，第一信令所触发的非周期性CSI-RS传输和/或非周期性SRS传输所使用的第二时域资源，在终端设备接收网络设备发送的HARQ-ACK的确认信息之后。通过限定非周期性CSI-RS传输和/或非周期性SRS传输所使用的时域资源，终端设备可以正确获知第一信令的内容，并且在调整天线参数后进行信道估计。保证了网络设备获取正确的信道估计结果，降低传输失败的概率。
上文中提到，第一指示信息用于指示调整发射天线参数存在多种方案，为了便于理解，下面结合附 图进行说明。
请参阅图8，图8为本申请实施例中天线参数调整的方法的另一种流程示意图。
本实施例中，在调整发射天线参数之前，终端设备使用2发射天线发送上行信号。从左到右，每一个方块为发送一次SRS所使用的时域资源。图8所示的终端设备中配置有两组周期性SRS资源。第1方块(横线填充)与第3方块(横线填充)中发送SRS所使用的周期性SRS资源为双端口SRS资源，终端设备在第1方块与第3方块所对应的时域资源中，使用两个发射天线端口发送SRS。第2方块(竖线填充)中发送SRS所使用的周期性SRS资源为单端口SRS资源，终端设备在第2方块所对应的时域资源中，使用一个发射天线端口发送SRS。图8中纵向虚线为终端设备调整发射天线参数时所对应的时刻，当终端设备调整发射天线参数后，即终端设备的最大发射天线端口数从双端口切换为单端口后，终端设备使用单端口发送SRS。若发射天线参数未作调整，则从左往右数第5方块(无填充)与第7方块(无填充)所对应的时域资源中，终端设备使用双端口SRS资源发送SRS。而调整发射天线参数后，第5方块与第7方块所对应的时域资源中终端设备不再使用双端口SRS资源发送SRS，仅保留单端口SRS资源发送SRS，即第4方块与第6方块所对应的时域资源中，终端设备使用单端口SRS资源发送SRS。
本申请实施例中，终端设备在调整发射天线参数后，由2发射天线调整至1发射天线，终端设备的最大发射天线数被限制为1发射天线。若终端设备中还预配置有发射天线端口数小于或等于最大发射天线数的SRS资源时，即单端口SRS资源时，终端设备仅使用该单端口SRS资源发送SRS，进一步降低终端设备的功耗。同时，空闲出双端口SRS资源所使用的时域资源。
请参阅图9，图9为本申请实施例中天线参数调整的方法的另一种流程示意图。
本实施例中，在调整发射天线参数之前，终端设备使用2发射天线发送上行信号。从左到右，每一个方块为发送一次SRS所使用的时域资源。图9所示的终端设备中配置有一组周期性SRS资源。第1方块(横线填充)与第2方块(横线填充)中发送SRS所使用的周期性SRS资源为双端口SRS资源，终端设备在第1方块与第2方块所对应的时域资源中，使用两个发射天线端口发送SRS。图9中纵向虚线为终端设备调整发射天线参数时所对应的时刻，当终端设备调整发射天线参数后，即终端设备的最大发射天线端口数从双端口切换为单端口后，终端设备选择当前双端口SRS资源中的任一端口发送SRS，并关闭剩余的一个端口。具体的，可以关闭端口号较大的端口，保留端口号较小的端口；或者关闭端口号较小的端口，保留端口号较大的端口，此处不作限定。
网络设备为终端设备配置的SRS是用于辅助天线选择的。比如终端设备向网络设备上报自己支持2T4R的能力，此时网络设备向终端设备配置相应的SRS资源如图9所示，第1方块以及第2方块分别为一个双端口SRS资源，经过两次发送可以完成一次轮发。当终端设备上行发送最大端口数由双端口切换为单端口后，在之前配置的时域资源上，只能采用单端口发射SRS。此时终端设备的能力退化为1T2R，即每次发送一个单端口SRS，经过两次发送可以完成一次轮发。
本申请实施例中，终端设备在调整发射天线参数后，由2发射天线调整至1发射天线，终端设备的最大发射天线数被限制为1发射天线。若终端设备中仅配置有一组发射天线端口数大于最大发射天线数的SRS资源时，即双端口SRS资源时，终端设备使用该双端口SRS资源中的任一端口发送SRS，并关闭剩余的另一个端口，进一步降低终端设备的功耗。
