Description

一种过热指示方法以及相关设备 技术领域
本申请涉及通信领域，尤其涉及一种过热指示方法以及相关设备。
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)。在NR中，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。为了提升通信质量，引入了天线轮发机制。而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可以使用探测参考信号(sounding reference signal，SRS)进行上行信道估计。结合MIMO技术，当SRS资源支持SRS天线轮发能力时，终端设备可以使用该SRS资源进行SRS轮发，同时对多根天线进行信道估计。网络设备根据终端设备接入时上报的无线能力(radio capability)向终端设备配置SRS资源。SRS天线轮发能力还可以称为SRS天线选择(antenna selection)能力。
当出现终端设备内部过热问题，可以通过降低终端设备能力或配置来降温解决过热问题。终端设备可以向网络设备上报辅助信息(user equipment assistance information)，用以通知网络设备此时终端设备所期望降低的能力或配置，该辅助信息由于是在终端设备处于过热状态时发送的，因此还可以称为过热指示信息。网络设备根据该上报的过热指示信息、对终端设备进行重配。
但终端设备过热时，网络设备对终端设备进行重配后，终端设备仍然支持上行参考信号天线轮发能力，终端设备仍然处于高功耗状态，无法解决过热问题。
发明内容
本申请实施例提供了一种过热指示方法以及相关设备，网络设备在接收到终端设备上报的辅助信息后，可以调整终端设备的SRS天线轮发能力，以降低终端设备功耗，解决终端设备过热问题。
第一方面，本申请实施例提供了一种过热指示方法，当网络设备向终端设备发送的RRC连接重配信息中，指示终端设备可以向网络设备发送过热指示信息后，终端设备处于设备内部过热状态时，该终端设备向网络设备发送第一过热指示信息，该第一过热指示信息承载于无线资源控制信息(radio resource control，RRC)中，该第一过热指示信息用于指示网络设备解决终端设备的过热问题，该无线资源控制信息还可以简称为RRC信令。该第一过热指示信息用于指示该终端设备需要不支持上行参考信号天线轮发能力，该上行参考信号可以为探测参考信号(sounding reference signal，SRS)。当该上行参考信号为SRS时，该第一过热指示信息用于指示该终端设备需要不支持SRS天线轮发能力。
该终端设备接收该网络设备发送的第一重配置信息，其中该第一重配置信息为该网络设备根据该第一过热指示信息生成的，该终端设备根据该第一重配置信息不支持上行参考信号天线轮发能力。当该上 行参考信号为SRS时，终端设备根据该第一重配置信息不支持SRS天线轮发能力。终端设备根据所述第一重配置信息不支持上行参考信号天线轮发能力，可以是将上行参考信号天线轮发能力去使能。
从上述第一方面中的技术方案可以看出，本申请实施例具有以下优点：终端设备在设备内部过热情况下，向网络设备发送第一过热指示信息，第一过热指示信息用于指示当前终端设备需要不支持上行参考信号天线轮发能力，网络设备根据第一过热指示信息生成第一重配置信息，终端设备根据第一重配置信息不支持上行参考信号天线轮发能力。终端设备不支持上行参考信号天线轮发能力，降低了终端设备的功耗，有效的解决终端设备过热问题。
结合第一方面，在第一方面实施例中，该第一过热指示信息具体包含不支持上行参考信号天线轮发能力指示信息，其中，该不支持上行参考信号天线轮发能力指示信息用于请求该网络设备发送该第一重配置信息。
具体的，当上行参考信号为SRS时，网络设备在接收第一过热指示信息后，可以根据承载有该第一过热指示信息的RRC信令本身，获知发送该第一过热指示信息的终端设备需要不支持SRS天线轮发能力，即网络设备接收到携带有过热指示信息的RRC信令时，默认发送该RRC信令的终端设备需要不支持SRS天线轮发能力。第一过热指示信息中还可以携带不支持SRS天线轮发能力指示信息，网络设备可以根据该不支持SRS天线轮发能力指示信息，获知终端设备需要不支持SRS天线轮发能力。终端设备可以通过不同的方式，使用第一过热指示信息请求网络设备发送第一重配置信息。提升了方案的灵活性。
结合第一方面，在第一方面实施例中，第一重配置信息可以承载于下行控制信息(downlink control information，DCI)、参考信号(reference signals，RS)、媒体接入控制层的控制信息(media access control control element，MAC CE)或无线资源控制信息(radio resource control，RRC)中的任意一种，具体承载于哪一种信令，由当前终端设备中所配置的用于上行参考信号天线轮发的上行参考信号轮发资源类型决定。
当上行参考信号为SRS时，用于SRS天线轮发的SRS资源在下文中简称为SRS资源，网络设备根据终端设备上报的第一过热指示信息获知该SRS资源类型。具体的：当配置的SRS资源为周期性SRS资源时，第一重配置信息承载于RRC信令中；当配置的SRS资源为非周期性SRS资源时，第一重配置信息承载于DCI信令中；当配置的SRS资源为半持续性SRS资源时，第一重配置信息承载于MAC CE信令中。
当该第一重配置信息承载于RRC信令时，该第一重配置信息具体用于该终端设备根据该第一重配置信息释放该终端设备中的该上行参考信号轮发资源或者不进行上行参考信号轮发，其中，该终端设备释放该终端设备中的该上行参考信号轮发资源后，该终端设备不支持该上行参考信号天线轮发能力。
当终端设备配置的SRS资源为非周期性SRS资源，网络设备可以通过不发送激活(activate)该非周期性SRS资源的DCI信令，达到该终端设备不支持SRS天线轮发能力的效果；也可以通过发送承载于DCI信令的第一重配置信息，该第一重配置信息用于去激活(deactivate)该非周期性SRS资源，达到该终端设备不支持SRS天线轮发能力的效果。根据上行参考信号轮发资源类型的不同，第一重配置信息可承载于不同的信令中，提升了方案的实现灵活性。
结合第一方面，在第一方面实施例中，终端设备根据网络设备发送的第一重配置信息，可以不支持上行参考信号轮发资源，具体可分为以下两种情况：一种是不支持全部频段资源的上行参考信号天线轮发能力，此时第一重配置信息中携带的是全部频段资源指示；另一种是不支持部分频段资源的上行参考信号天线轮发能力，此时第一重配置信息中携带的是部分频段资源指示。
终端设备根据携带全部频段资源指示的该第一重配置信息释放全部频段资源的该上行参考信号轮发资源，其中，该终端设备释放该终端设备中该全部频段资源的该上行参考信号轮发资源后，该终端设 备不支持该全部频段资源中的该上行参考信号天线轮发能力，或该终端设备根据携带部分频段资源指示的该第一重配置信息释放部分频段资源的该上行参考信号轮发资源，其中，该终端设备释放该终端设备中该部分频段资源的该上行参考信号轮发资源后，该终端设备不支持该部分频段资源中的该上行参考信号天线轮发能力。
具体的释放上行参考信号轮发资源的过程，可以为删除配置于终端设备内部的上行参考信号轮发资源。当第一过热指示信息指示的是：不支持全部频段资源的上行参考信号轮发天线轮发能力时，终端设备删除所有频段资源的上行参考信号轮发资源；当第一过热指示信息指示的是：不支持部分频段资源的上行参考信号轮发天线轮发能力，终端设备删除对应的部分频段资源的上行参考信号轮发资源。终端设备可以根据实际网络情况释放全部频段资源上的上行参考信号轮发资源，或者释放部分频段资源上的上行参考信号轮发资源，既可以实现快速的降温，也可以在保留部分上行参考信号轮发资源的情况下实现慢速的降温。获得了常用频段资源的信道估计结果，在保证常用频段资源下的通信质量，也通过不进行不常用频段资源的上行参考信号轮发，达到了降低功耗的目的。
结合第一方面，在第一方面实施例中，当该第一过热指示信息中还携带有降低多入多出层数(multiple-input multiple-output layer，MIMO layer)指示时，第一重配置信息还用于调整终端设备中上行MIMO能力和/或下行MIMO能力(MIMO layer)。具体的，调整终端设备中上行MIMO能力为：调整终端设备中的发送天线数目以及发射射频链路数目；调整终端设备中下行MIMO能力为：调整终端设备中的接收天线以及接收射频链路数目。
该终端设备根据该第一重配置信息调整该终端设备的发送天线数目以及发射射频链路数目，和/或该终端设备根据该第一重配置信息调整该终端设备的接收天线以及接收射频链路数目。
当终端设备处于过热状态时，网络设备除了指示终端设备释放上行参考信号轮发资源以降低功耗外，还可以指示终端设备调整MIMO能力，具体的，调整终端设备的射频链路和/或天线数目，以实现更进一步的降低功耗，使得终端设备的温度更快恢复正常。同时，该降低MIMO layer指示还可以携带在第一重配置信息中，简化步骤。
结合第一方面，在第一方面实施例中，终端设备接收网络设备发送的该第一重配置信息之后，由于终端设备已经不支持上行参考信号天线轮发能力，因此网络设备无法通过上行参考信号天线轮发获得与该终端设备之间的上行信道估计的结果。因此网络设备可以发起下行信道估计，获得下行信道估计的结果。根据信道互异性，网络设备可以根据该下行信道估计的结果获得上行信道估计的结果。需要说明的是，在非时分双工(time division duplexing，TDD)系统中，也可以通过下行信道估计的结果获得上行信道估计的结果。
终端设备接收该网络设备发送的下行参考信号，其中，该下行参考信号用于下行信道估计；终端设备通过接收该下行参考信号，进行下行信道估计；终端设备根据下行参考信号确定下行参考信号的反馈信息。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的反馈信息，其中，下行参考信号的反馈信息包含下行信道估计的结果。需要说明的是，该下行参考信号可以为信道状态信息参考信号(channel state information reference signal，CSI-RS)，还可以为其它的下行参考信号，例如：同步信号/广播信道块(synchronization signal/physical broadcast channel block，SS/PBCH Block)。当下行参考信号为CSI-RS时，该下行参考信号的反馈信息为信道状态信息报告(channel state information report，CSI report)。当终端设备不支持上行参考信号天线轮发能力后，终端设备还可以通过接收网络设备下发的下行参考信号，以进行下行信道估计。基于信道互异性， 该下行信道估计的结果也可以应用于上行数据调度中，保证了数据传输的准确性。
结合第一方面，在第一方面实施例中，在网络设备接收终端设备发送的第一过热指示信息之后，网络设备启动定时器，经过第一时间间隔后，该终端设备接收该网络设备发送的第二重配置信息，该第二重配置信息用于重新配置该终端设备中的该上行参考信号轮发资源，其中，该终端设备重新配置该终端设备中的该上行参考信号轮发资源后，该终端设备支持该上行参考信号天线轮发能力。
当第一过热指示信息中还携带有减少MIMO layer指示时，该第二重配置信息还可以重新调整终端设备中上行MIMO能力和/或下行MIMO能力(MIMO layer)。具体的，调整终端设备中上行MIMO能力为：调整终端设备中的发送天线数目以及发射射频链路数目；调整终端设备中下行MIMO能力为：调整终端设备中的接收天线以及接收射频链路数目。其中，调整发送天线数目或接收天线数目的情况为，降低MIMO layer指示所指示的降低值低于当前终端设备的天线数目，例如第一过热指示信息中的降低MIMO layer指示为从4layer降低至2layer时，终端设备根据该第二重配置信息将接收天线数目从2调整为4。
终端设备接收网络设备发送的该第一重配置信息之后，终端设备根据该第一重配置信息释放上行参考信号轮发资源，终端设备不支持上行参考信号轮发能力。此时网络设备会设定第一时间间隔，经过第一时间间隔之后，若终端设备并未发送新的过热指示信息时，可以认为该终端设备的温度已恢复正常，此时终端设备根据网络设备的第二重配置信息，重配配置上行参考信号轮发资源，重新支持上行参考信号轮发能力。以保证温度恢复正常后的终端设备，可以及时恢复上行参考信号天线轮发能力。
结合第一方面，在第一方面实施例中，在网络设备接收终端设备发送的第一过热指示信息之后，网络设备启动定时器，在第一时间间隔内，若该终端设备从温度过热状态恢复为温度正常状态，该终端设备向该网络设备发送第二过热指示信息，该第二过热指示信息用于指示当前终端设备温度已恢复正常；
该终端设备接收该网络设备发送的第二重配置信息，该第二重配置信息用于重新配置该终端设备中的该上行参考信号轮发资源，其中，该终端设备重新配置该终端设备中的该上行参考信号轮发资源后，该终端设备支持该上行参考信号天线轮发能力。
终端设备接收网络设备发送的该第一重配置信息之后，终端设备根据该第一重配置信息释放上行参考信号轮发资源，终端设备不支持上行参考信号轮发能力。此时网络设备会设定第一时间间隔，在第一时间间隔内，若终端设备检测到内部的温度已恢复正常，终端设备向网络设备发送新的过热指示信息，该过热指示信息用于指示当前终端设备温度已恢复正常，该过热指示信息称为第二过热指示信息。网络设备根据该第二过热指示信息，获知该终端设备的温度已恢复正常，并向终端设备发送第二重配置信息，此时终端设备根据网络设备的第二重配置信息，重配配置上行参考信号轮发资源，重新支持上行参考信号轮发能力。当第一过热指示信息中还携带有减少MIMO layer指示时，该第二重配置信息还可以重新调整终端设备中上行MIMO能力和/或下行MIMO能力(MIMO layer)。以保证温度恢复正常后的终端设备，可以及时恢复上行参考信号天线轮发能力。
结合第一方面，在第一方面实施例中，在网络设备接收终端设备发送的第一过热指示信息之后，网络设备启动定时器，在第一时间间隔内，终端设备的温度仍然为过热状态时，终端设备可以向网络设备发送过热指示信息，以告知网络设备当前终端设备温度仍然为过热状态，该过热指示信息称为第三过热指示信息。当终端设备向网络设备发送第三过热指示信息之后，网络设备根据该第三过热指示信息，重置定时器。重置定时器后，终端设备可能出现下列两种情况：第一种情况、温度恢复正常；第二种情况、温度仍然为异常状态。
第一种情况：重置定时器后，且经过第一时间间隔后，若终端设备检测到内部的温度已恢复正常， 终端设备向网络设备发送新的过热指示信息，该过热指示信息用于指示当前终端设备温度已恢复正常，该过热指示信息称为第二过热指示信息。网络设备根据该第二过热指示信息，获知该终端设备的温度已恢复正常，并向终端设备发送第二重配置信息，此时终端设备根据网络设备的第二重配置信息，重配配置上行参考信号轮发资源，重新支持上行参考信号轮发能力。
第二种情况：重置定时器后，且在第一时间间隔内，终端设备的温度仍然为过热状态时，终端设备可以向网络设备发送第三过热指示信息，以告知网络设备当前终端设备温度仍然为过热状态。当终端设备向网络设备发送第三过热指示信息之后，网络设备根据该第三过热指示信息，重置定时器。网络设备不断的重置定时器，直到终端设备的温度恢复正常。当终端设备的温度恢复正常后，终端设备可以根据网络设备的第二重配置信息，重新配置上行参考信号轮发资源，重新支持上行参考信号轮发能力。在保证温度恢复正常后的终端设备，可以及时恢复上行参考信号天线轮发能力的同时，温度仍然为过热状态的终端设备不会错误的重新配置上行参考信号轮发资源，以保证仍然处于过热状态的终端设备处于低功耗状态。
第二方面，本申请实施例提供了一种过热指示方法，当网络设备向终端设备发送的RRC连接重配信息中，指示终端设备可以向网络设备发送过热指示信息后，终端设备处于设备内部过热状态时，网络设备接收该终端设备发送的第一过热指示信息，该第一过热指示信息承载于无线资源控制信息(radio resource control，RRC)中，该第一过热指示信息用于指示网络设备解决终端设备的过热问题，该无线资源控制信息还可以简称为RRC信令。该第一过热指示信息用于指示该终端设备需要不支持上行参考信号天线轮发能力，该上行参考信号可以为探测参考信号(sounding reference signal，SRS)。当该上行参考信号为SRS时，该第一过热指示信息用于指示该终端设备需要不支持SRS天线轮发能力。
网络设备向该终端设备发送第一重配置信息，其中该第一重配置信息为该网络设备根据该第一过热指示信息生成的，该终端设备根据该第一重配置信息不支持上行参考信号天线轮发能力。当该上行参考信号为SRS时，终端设备根据该第一重配置信息不支持SRS天线轮发能力。
从上述第二方面中的技术方案可以看出，本申请实施例具有以下优点：终端设备在设备内部过热情况下，网络设备接收终端设备发送的第一过热指示信息，第一过热指示信息用于指示当前终端设备需要不支持上行参考信号天线轮发能力，网络设备根据第一过热指示信息生成第一重配置信息，终端设备根据第一重配置信息不支持上行参考信号天线轮发能力。终端设备不支持上行参考信号天线轮发能力，降低了终端设备的功耗，有效的解决终端设备过热问题。
结合第二方面，在第二方面实施例中，该第一过热指示信息具体包含不支持上行参考信号天线轮发能力指示信息，其中，该不支持上行参考信号天线轮发能力指示信息用于请求该网络设备发送该第一重配置信息。
具体的，当上行参考信号为SRS时，网络设备在接收第一过热指示信息后，可以根据承载有该第一过热指示信息的RRC信令本身，获知发送该第一过热指示信息的终端设备需要不支持SRS天线轮发能力，即网络设备接收到携带有过热指示信息的RRC信令时，默认发送该RRC信令的终端设备需要不支持SRS天线轮发能力。第一过热指示信息中还可以携带不支持SRS天线轮发能力指示信息，网络设备可以根据该不支持SRS天线轮发能力指示信息，获知终端设备需要不支持SRS天线轮发能力。终端设备可以通过不同的方式，使用第一过热指示信息请求网络设备发送第一重配置信息。提升了方案的灵活性。
结合第二方面，在第二方面实施例中，第一重配置信息可以承载于下行控制信息(downlink control information，DCI)、参考信号(reference signals，RS)、媒体接入控制层的控制信息(media access  control control element，MAC CE)或无线资源控制信息(radio resource control，RRC)中的任意一种，具体承载于哪一种信令，由当前终端设备中所配置的用于上行参考信号天线轮发的上行参考信号轮发资源类型决定。
当上行参考信号为SRS时，用于SRS天线轮发的SRS资源在下文中简称为SRS资源，网络设备根据终端设备上报的第一过热指示信息获知该SRS资源类型。具体的：当配置的SRS资源为周期性SRS资源时，第一重配置信息承载于RRC信令中；当配置的SRS资源为非周期性SRS资源时，第一重配置信息承载于DCI信令中；当配置的SRS资源为半持续性SRS资源时，第一重配置信息承载于MAC CE信令中。
当该第一重配置信息承载于RRC信令时，该第一重配置信息具体用于该终端设备根据该第一重配置信息释放该终端设备中的该上行参考信号轮发资源或者不进行上行参考信号轮发，其中，该终端设备释放该终端设备中的该上行参考信号轮发资源后，该终端设备不支持该上行参考信号天线轮发能力。
当终端设备配置的SRS资源为非周期性SRS资源，网络设备可以通过不发送激活(activate)该非周期性SRS资源的DCI信令，达到该终端设备不支持SRS天线轮发能力的效果；也可以通过发送承载于DCI信令的第一重配置信息，该第一重配置信息用于去激活(deactivate)该非周期性SRS资源，达到该终端设备不支持SRS天线轮发能力的效果。根据上行参考信号轮发资源类型的不同，第一重配置信息可承载于不同的信令中，提升了方案的实现灵活性。
结合第二方面，在第二方面实施例中，网络设备通过向终端设备发送第一重配置信息，可以指示终端设备不支持上行参考信号轮发资源，具体可分为以下两种情况：一种是不支持全部频段资源的上行参考信号天线轮发能力，此时第一重配置信息中携带的是全部频段资源指示；另一种是不支持部分频段资源的上行参考信号天线轮发能力，此时第一重配置信息中携带的是部分频段资源指示。
该网络设备向该终端设备发送携带全部频段资源指示的该第一重配置信息，以使得该终端设备根据携带该全部频段资源指示的该第一重配置信息，释放该终端设备中全部频段资源的该上行参考信号轮发资源，其中，该终端设备释放该终端设备中该全部频段资源的该上行参考信号轮发资源后，该终端设备不支持该全部频段资源中的该上行参考信号天线轮发能力，或该网络设备向该终端设备发送携带部分频段资源指示的该第一重配置信息，以使得该终端设备根据携带该部分频段资源指示的该第一重配置信息，释放该终端设备中部分频段资源的该上行参考信号轮发资源，其中，该终端设备释放该终端设备中该部分频段资源的该上行参考信号轮发资源后，该终端设备不支持该部分频段资源中的该上行参考信号天线轮发能力。
具体的释放上行参考信号轮发资源的过程，可以为删除配置于终端设备内部的上行参考信号轮发资源。当第一过热指示信息指示的是：不支持全部频段资源的上行参考信号轮发天线轮发能力时，终端设备删除所有频段资源的上行参考信号轮发资源；当第一过热指示信息指示的是：不支持部分频段资源的上行参考信号轮发天线轮发能力，终端设备删除对应的部分频段资源的上行参考信号轮发资源。终端设备可以根据实际网络情况释放全部频段资源上的上行参考信号轮发资源，或者释放部分频段资源上的上行参考信号轮发资源，既可以实现快速的降温，也可以在保留部分上行参考信号轮发资源的情况下实现慢速的降温。获得了常用频段资源的信道估计结果，在保证常用频段资源下的通信质量，也通过不进行不常用频段资源的上行参考信号轮发，达到了降低功耗的目的。
结合第二方面，在第二方面实施例中，当该第一过热指示信息中还携带有降低MIMO layer指示时，第一重配置信息还用于调整终端设备中上行MIMO能力和/或下行MIMO能力(MIMO layer)。具体的，调整终端设备中上行MIMO能力为：调整终端设备中的发送天线数目以及发射射频链路数目；调整终端设 备中下行MIMO能力为：调整终端设备中的接收天线以及接收射频链路数目。
该终端设备根据该第一重配置信息调整该终端设备的发送天线数目以及发射射频链路数目，和/或该终端设备根据该第一重配置信息调整该终端设备的接收天线以及接收射频链路数目。
当终端设备处于过热状态时，网络设备除了指示终端设备释放上行参考信号轮发资源以降低功耗外，还可以指示终端设备调整MIMO能力，具体的，调整终端设备的射频链路和/或天线数目，以实现更进一步的降低功耗，使得终端设备的温度更快恢复正常。同时，该降低MIMO layer指示还可以携带在第一重配置信息中，简化步骤。
结合第二方面，在第二方面实施例中，网络设备向终端设备发送第一重配置信息之后，由于终端设备已经不支持上行参考信号天线轮发能力，因此网络设备无法通过上行参考信号天线轮发获得与该终端设备之间的上行信道估计的结果。因此网络设备可以发起下行信道估计，获得下行信道估计的结果。根据信道互异性，网络设备可以根据该下行信道估计的结果获得上行信道估计的结果。需要说明的是，在非时分双工(time division duplexing，TDD)系统中，也可以通过下行信道估计的结果获得上行信道估计的结果。
首先网络设备向该终端设备发送下行参考信号，其中，该下行参考信号用于下行信道估计，终端设备根据下行参考信号确定下行参考信号的反馈信息，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)向网络设备发送该下行参考信号的反馈信息，其中，下行参考信号的反馈信息包含下行信道估计的结果；
网络设备接收该终端设备发送的该下行参考信号的反馈信息，网络设备根据该下行参考信号的反馈信息获得上行信道估计的结果。
需要说明的是，该下行参考信号可以为信道状态信息参考信号(channel state information reference signal，CSI-RS)，还可以为其它的下行参考信号，例如：同步信号/广播信道块(synchronization signal/physical broadcast channel block，SS/PBCH Block)。当下行参考信号为CSI-RS时，该下行参考信号的反馈信息为信道状态信息报告(channel state information report，CSI report)。当终端设备不支持上行参考信号天线轮发能力后，终端设备还可以通过接收网络设备下发的下行参考信号，以进行下行信道估计。基于信道互异性，该下行信道估计的结果也可以应用于上行数据调度中，保证了数据传输的准确性。
结合第二方面，在第二方面实施例中，在网络设备接收终端设备发送的第一过热指示信息之后，网络设备启动定时器，经过第一时间间隔后，该网络设备向该终端设备发送第二重配置信息，该第二重配置信息用于重新配置该终端设备中的该上行参考信号轮发资源，其中，该终端设备重新配置该终端设备中的该上行参考信号轮发资源后，该终端设备支持该上行参考信号天线轮发能力。
当第一过热指示信息中还携带有减少MIMO layer指示时，该第二重配置信息还可以重新调整终端设备中上行MIMO能力和/或下行MIMO能力(MIMO layer)。具体的，调整终端设备中上行MIMO能力为：调整终端设备中的发送天线数目以及发射射频链路数目；调整终端设备中下行MIMO能力为：调整终端设备中的接收天线以及接收射频链路数目。其中，调整发送天线数目或接收天线数目的情况为，降低MIMO layer指示所指示的降低值低于当前终端设备的天线数目，例如第一过热指示信息中的降低MIMO layer指示为从4layer降低至2layer时，终端设备根据该第二重配置信息将接收天线数目从2调整为4。
网络设备向终端设备发送第一重配置信息之后，终端设备根据该第一重配置信息释放上行参考信号轮发资源，终端设备不支持上行参考信号轮发能力。此时网络设备会设定第一时间间隔，经过第一时间 间隔之后，若终端设备并未发送新的过热指示信息时，可以认为该终端设备的温度已恢复正常，该网络设备向该终端设备发送第二重配置信息，此时终端设备根据网络设备的第二重配置信息，重配配置上行参考信号轮发资源，重新支持上行参考信号轮发能力。以保证温度恢复正常后的终端设备，可以及时恢复上行参考信号天线轮发能力。
结合第二方面，在第二方面实施例中，在网络设备接收终端设备发送的第一过热指示信息之后，网络设备启动定时器，在第一时间间隔内，若该终端设备从温度过热状态恢复为温度正常状态，网络设备接收到该终端设备发送的第二过热指示信息，该第二过热指示信息用于指示当前终端设备温度已恢复正常；
网络设备向该终端设备发送第二重配置信息，该终端设备接收该网络设备发送的第二重配置信息，该第二重配置信息用于重新配置该终端设备中的该上行参考信号轮发资源，其中，该终端设备重新配置该终端设备中的该上行参考信号轮发资源后，该终端设备支持该上行参考信号天线轮发能力。
网络设备向终端设备发送第一重配置信息之后，终端设备根据该第一重配置信息释放上行参考信号轮发资源，终端设备不支持上行参考信号轮发能力。此时网络设备会设定第一时间间隔，在第一时间间隔内，若终端设备检测到内部的温度已恢复正常，终端设备向网络设备发送新的过热指示信息，该过热指示信息用于指示当前终端设备温度已恢复正常，该过热指示信息称为第二过热指示信息。网络设备根据该第二过热指示信息，获知该终端设备的温度已恢复正常，并向终端设备发送第二重配置信息，此时终端设备根据网络设备的第二重配置信息，重配配置上行参考信号轮发资源，重新支持上行参考信号轮发能力。当第一过热指示信息中还携带有减少MIMO layer指示时，该第二重配置信息还可以重新调整终端设备中上行MIMO能力和/或下行MIMO能力(MIMO layer)。以保证温度恢复正常后的终端设备，可以及时恢复上行参考信号天线轮发能力。
结合第二方面，在第二方面实施例中，在网络设备接收终端设备发送的第一过热指示信息之后，网络设备启动定时器，在第一时间间隔内，终端设备的温度仍然为过热状态时，终端设备可以向网络设备发送过热指示信息，以告知网络设备当前终端设备温度仍然为过热状态，该过热指示信息称为第三过热指示信息。当网络设备接收终端设备发送的第三过热指示信息之后，网络设备根据该第三过热指示信息，重置定时器。重置定时器后，终端设备可能出现下列两种情况：第一种情况、温度恢复正常；第二种情况、温度仍然为异常状态。
第一种情况：重置定时器后，且经过第一时间间隔后，若终端设备检测到内部的温度已恢复正常，终端设备向网络设备发送新的过热指示信息，该过热指示信息用于指示当前终端设备温度已恢复正常，该过热指示信息称为第二过热指示信息。网络设备根据该第二过热指示信息，获知该终端设备的温度已恢复正常，并向终端设备发送第二重配置信息，此时终端设备根据网络设备的第二重配置信息，重配配置上行参考信号轮发资源，重新支持上行参考信号轮发能力。

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送天线和接收天线，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个天线与网络设备进行上行通信。如果终端设备使用2个天线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。如果终端设备使用1个天线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，也可以同时使用两个射频链路模拟成一个天线，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t1r2。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t2r4。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t1r2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，t2r4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、发送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上行参考信号，终端设备通过下行信道接收网络设备发送的下行参考信号，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。终端设备还可以通过接收网络设备发送的同步信号/广播信道块(synchronization signal/physical broadcast channel block，SS/PBCH Block)进行下行信道估计，具体信道估计的过程与使用CSI-RS类似，此处不再赘述。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或同步信号/广播信道块，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的反馈信息以完成信道估计，本实施例中仅以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：网络设备通过无线资源控制信息(radio resource control，RRC)，该无线资源控制信息简称为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资源的媒体接入控制层的控制信息(media access control control element，MAC CE)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MAC CE，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资源可分为下列三种：周期性SRS资源、非周期性SRS资源以及半持续性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。
半持续性SRS资源：网络设备通过RRC信令向终端设备配置半持续性SRS资源，此时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资源的媒体接入控制层的控制信息(media access control control element，MAC CE)后，终端设备才会周期性发送该SRS。当终端设备不再发送该SRS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SRS资源的MAC CE，以去激活的终端设备中的该半持续性SRS资源。
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资源或CSI-RS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。在非TDD系统中也可以仅通过配置SRS资源或CSI-RS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，在非TDD系统中信道估计结果误差大于TDD系统中的误差。
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 的发送天线数，终端设备按照SRS资源所指示的发送天线向网络设备发送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送天线示意图。图3中该终端设备中配置有一个发射射频电路与四根发送天线，该发射射频电路可以与任意一根发送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送天线向网络设备发送电磁波时，不同的发送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送天线，造成该发送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送天线之间进行切换，终端设备连续发送多个SRS，这些SRS通过不同的发送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，确定哪一根发送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：t1r2、t1r4、t2r4、t1r4-t2r4、t1r1、t2r2或t4r4等。下面举例说明，t1r2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。t2r4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。t1r4-t2r4为该终端设备既支持t1r4的SRS天线轮发也支持t2r4的SRS天线轮发。
当终端设备接入网络设备所在的小区时，会向网络设备上报自己的无线能力(radio capability)，其中包括针对终端设备支持的每一种频带组合(band combination)中的每一频带(band)上报SRS天线轮发(sounding reference signal antenna switch)能力。网络设备可以根据终端设备上报的SRS天线轮发能力，为终端设备配置相应的用于SRS天线轮发目的SRS资源。例如代码为“supportedSRS-TxPortSwitch t1r2”，终端设备向网络设备上报的SRS天线轮发能力为支持一个发射射频链路与两根天线，网络设备根据终端设备上报的SRS天线轮发能力向终端设备配置用于SRS天线轮发的SRS资源。
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。当出现终端设备内部过热问题，可以通过降低终端设备能力或配置来降温解决过热问题。终端设备可以向网络设备上报辅助信息(user equipment assistance information)，用以通知网络设备此时终端设备所期望降低的能力或配置，该辅助信息由于是在终端设备处于过热状态时发送的，因此还可以称为过热指示信息。网络设备根据该上报的过热指示信息、对终端设备进行重配。下面结合图4进行详细说明，图4为本申请实施例中终端设备向网络设备发送辅助信息的流程示意图。
步骤401、网络设备向终端设备发送RRC连接重配信息。
步骤401中，网络设备向终端设备发送RRC连接重配信息，该RRC连接重配信息中包括当终端设备过热时的相关配置信息，例如指示终端设备是否可以发送过热相关的指示信息给网络设备，以及终端设备过热时相关的禁止定时器的取值。
步骤402、终端设备向网络设备发送过热指示信息。
步骤402中，当网络设备向终端设备发送的RRC连接重配信息中，指示终端设备可以向网络设备发送过热指示信息后，当终端设备处于设备过热状态时，终端设备可以向网络设备发送过热指示信息。该过热指示信息用于指示网络设备解决终端设备的过热问题。
在长期演进(long term evolution，LTE)场景或E-UTRA-NR双连接(e-utra-nr dual connectivity，EN-DC)场景中，终端设备上报的过热指示信息中可以包含：上行和/或下行终端设备类型(UE category)，和/或，上行和/或下行最大辅(secondary)载波(component carrier，CC)/辅小区(SCell)数。其中上行和/或下行终端设备类型中还包含多入多出层数(multiple-input multiple-output layer，MIMO layer)。
在独立组网架构(standalone，SA)或NR-E-UTRA双连接(nr-e-utra dual connectivity，NE-DC)或NR-NR双连接(nr-nr dual connectivity，NR-DC)场景中，终端设备上报的过热指示信息中可以包含：上行和/或下行最大辅(secondary)载波(component carrier，CC)/辅小区(SCell)数，和/或，每个频段(低频FR1及高频FR2)上行和/或下行最大聚合带宽，和/或，每个频段(低频FR1及高频FR2)上每个服务小区的上行和/或下行最大MIMO layer数。
现有技术中，当终端设备出现过热问题时，终端设备向网络设备上报过热指示信息，网络设备可以根据该过热指示信息重新配置终端设备使用低能力的MIMO，例如：过热前，终端设备使用的下行MIMO能力是4*4MIMO，上行MIMO能力是4*4MIMO。当上报过热指示信息后，终端设备根据网络设备的重配置信息，上行MIMO能力是4*4MIMO。过热前终端设备使用上行MIMO能力是4*4MIMO，终端设备需要打开4条发射射频链路和4个发送天线；终端设备接收重配置信息后使用上行MIMO能力是2*2MIMO，终端设备针对低能力2*2MIMO只需要2条发射射频链路和2个发送天线，因此可以降低功耗，解决过热问题。然而，调整MIMO能力与调整SRS天线轮发能力是解耦的，若终端设备在过热前配置的SRS天线轮发能力是t2r4，则在接收网络设备发送的重配置信息之后，依然需要开启2条发射射频链路和4个发送天线，无法降低功耗，解决过热问题。而现有技术中，终端设备无法降低(fallback)SRS天线轮发能力，这导致了终端设备无法有效解决过热问题。
另一方面，终端设备根据重配置信息降低了MIMO能力后，终端设备根据该重配置信息关闭了对应的射频链路与天线，此时终端设备无法再使用配置于该终端设备内部的SRS资源正常的完成天线轮发。即此时的终端设备无法支持正常的天线轮发，造成部分SRS资源的浪费。并且，由于终端设备进行SRS天线轮发的目的是获得正确的信道估计结果，当终端设备通过被关闭的射频链路与天线向网络设备发送SRS，该信道与终端设备实际上能够使用的信道不一致，这两个信道的质量不一致，造成了信道估计结果的错误，网络设备使用该信道估计结果调度数据，也会造成误码率提升，影响通信质量。
基于上述问题，本申请实施例提出了一种方案，当终端设备过热时，网络设备在接收到终端设备上报的过热指示信息后，可以调整终端设备的SRS天线轮发能力，以降低终端设备功耗，解决终端设备过热问题。
下面结合附图对本申请实施例进行描述，请参阅图5，图5为本申请实施例中过热指示方法的一种实施例示意图，本申请实施例提供的一种过热指示的方法包括：
501、终端设备向网络设备发送第一过热指示信息。
本实施例中，当终端设备处于过热状态时，且网络设备允许终端设备向网络设备发送过热指示信息时，终端设备向网络设备发送第一过热指示信息，该第一过热指示信息承载于RRC信令中。该第一过热指示信息用于指示该终端设备需要不支持SRS天线轮发能力。网络设备在接收第一过热指示信息后，可 以根据承载有该第一过热指示信息的RRC信令本身，获知发送该第一过热指示信息的终端设备需要不支持SRS天线轮发能力，即网络设备接收到携带有过热指示信息的RRC信令时，默认发送该RRC信令的终端设备需要不支持SRS天线轮发能力。第一过热指示信息中还可以携带不支持SRS天线轮发能力指示信息，网络设备可以根据该不支持SRS天线轮发能力指示信息，获知终端设备需要不支持SRS天线轮发能力。具体的，该不支持SRS天线轮发能力指示信息可以为以下代码：“ENUMERATED supportedSRS-TxPortSwitch{notsupported}OPTIONAL”。
不支持SRS天线轮发能力具体可以分为以下两种情况：一种是不支持全部频段资源的SRS天线轮发能力；另一种是不支持部分频段资源的SRS天线轮发能力，例如频分双工长期演进技术(frequency division duplexing-long term evolution，FDD-LTE)中的FDD-LTE B1、2、3、4、5、6、7、8、12、17、18、19、20或26频段中的至少一种。网络设备可以根据当前网络实际情况，配置终端设备不支持哪一些频段资源的SRS天线轮发能力，或者是根据终端设备的第一过热指示信息中携带的全部频段资源指示或部分频段资源指示，指示终端设备不支持哪一些频段资源的SRS天线轮发能力，其中，当第一过热指示信息中携带的是全部频段资源指示时，网络设备指示终端设备不支持全部频段资源的SRS天线轮发能力；当第一过热指示信息中携带的是部分频段资源指示时，网络设备指示终端设备不支持部分频段资源的SRS天线轮发能力，具体的不支持哪一部分频段资源由部分频段资源指示决定。
需要说明的是，当终端设备需要降低MIMO能力时，该第一过热指示信息中还携带有降低MIMO layer指示。
502、网络设备向终端设备发送第一重配置信息。
本实施例中，网络设备在接收到终端设备发送的第一过热指示信息之后，向终端设备发送第一重配置信息，终端设备根据第一重配置信息不支持SRS天线轮发能力。该第一重配置信息可以承载于下行控制信息(downlink control information，DCI)、参考信号(reference signals，RS)、媒体接入控制层的控制信息(media access control control element，MAC CE)或无线资源控制信息(radio resource control，RRC)中的任意一种，具体承载于哪一种信令，由当前终端设备中所配置的用于SRS天线轮发的SRS资源类型决定，用于SRS天线轮发的SRS资源在下文中简称为SRS资源，网络设备根据终端设备上报的第一过热指示信息获知该SRS资源类型。具体的：当配置的SRS资源为周期性SRS资源时，第一重配置信息承载于RRC信令中；当配置的SRS资源为非周期性SRS资源时，第一重配置信息承载于DCI信令中；当配置的SRS资源为半持续性SRS资源时，第一重配置信息承载于MAC CE信令中。
其中，当终端设备配置的SRS资源为非周期性SRS资源，网络设备可以通过不发送激活(activate)该非周期性SRS资源的DCI信令，达到该终端设备不支持SRS天线轮发能力的效果；也可以通过发送承载于DCI信令的第一重配置信息，该第一重配置信息用于去激活(deactivate)该非周期性SRS资源，达到该终端设备不支持SRS天线轮发能力的效果。即当终端设备中配置的SRS资源为非周期性SRS资源时，步骤502为可选步骤。
需要说明的是，该SRS资源由于是用于SRS天线轮发的，而SRS天线轮发中存在选择发送天线进行发送SRS的步骤，因此该SRS资源还可以称为用于天线选择(antenna selection)功能的SRS资源。
当该第一过热指示信息中还携带有降低MIMO layer指示时，第一重配置信息还用于调整终端设备中上行MIMO能力和/或下行MIMO能力(MIMO layer)。具体的，调整终端设备中上行MIMO能力为：调整终端设备中的发送天线数目以及发射射频链路数目；调整终端设备中下行MIMO能力为：调整终端设备中的接收天线以及接收射频链路数目。其中，调整发送天线数目或接收天线数目的情况为，降低MIMO layer指示所指示的降低值低于当前终端设备的天线数目，例如当降低MIMO layer指示为从4layer降 低至2layer，终端设备中接收天线数目为4时，终端设备根据该第一重配置信息将接收天线数目从4调整为2。
503、终端设备不支持SRS天线轮发能力。
本实施例中，根据终端设备内部所配置的SRS资源类型的不同，终端设备不支持SRS天线轮发能力可以通过多种方法实现。下面分别举例说明：
当终端设备内部配置的为周期性SRS资源时，终端设备根据承载于RRC信令中的第一重配置信息，释放(fallback)该周期性SRS资源，当终端设备释放了该SRS资源后，终端设备无法再进行SRS天线轮发，实现了终端设备不支持SRS天线轮发能力的效果。也可以根据该第一重配置信息去激活该SRS资源，使得终端设备无法再进行SRS天线轮发，实现终端设备不支持SRS天线轮发能力的结果。
当终端设备内部配置的为非周期性SRS资源时，终端设备根据承载于DCI信令中的第一重配置信息，释放该非周期性SRS资源，当终端设备释放了该SRS资源后，终端设备无法再进行SRS天线轮发，实现了终端设备不支持SRS天线轮发能力的效果。另外，终端设备中配置的为非周期性SRS资源时，终端设备每次执行SRS天线轮发，都需要接收网络设备发送的激活SRS资源指令，该指令承载于DCI信令中。因此，网络设备可以通过不发送激SRS资源指令，使得终端设备无法再进行SRS天线轮发，实现终端设备不支持SRS天线轮发能力的结果。
当终端设备内部配置的为半持续性SRS资源时，终端设备根据承载于MAC CE信令中的第一重配置信息，释放该半持续性SRS资源，当终端设备释放了该SRS资源后，终端设备无法再进行SRS天线轮发，实现了终端设备不支持SRS天线轮发能力的效果。也可以根据该第一重配置信息去激活该SRS资源，使得终端设备无法再进行SRS天线轮发，实现终端设备不支持SRS天线轮发能力的效果。
具体的释放SRS资源的过程，可以为删除配置于终端设备内部的SRS资源。
当第一过热指示信息指示的是：不支持全部频段资源的SRS天线轮发能力时，终端设备释放所有频段资源的SRS资源；当第一过热指示信息指示的是：不支持部分频段资源的SRS天线轮发能力，终端设备释放对应的部分频段资源的SRS资源。
504、网络设备向终端设备发送下行参考信号。
本实施例中，由于终端设备已经不支持SRS天线轮发能力，因此网络设备无法通过SRS天线轮发获得与该终端设备之间的上行信道估计的结果。因此网络设备可以发起下行信道估计，获得下行信道估计的结果。根据信道互异性，网络设备可以根据该下行信道估计的结果获得上行信道估计的结果。需要说明的是，在非TDD系统中，也可以通过下行信道估计的结果获得上行信道估计的结果。
本实施例中，网络设备向终端设备发送下行参考信号，终端设备通过接收该下行参考信号，进行下行信道估计。需要说明的是，该下行参考信号可以为CSI-RS，还可以为其它的下行参考信号，此处不作限定。
505、终端设备向网络设备发送下行参考信号的反馈信息。
本实施例中，终端设备在接收到下行参考信号之后，终端设备根据下行参考信号确定下行参考信号的反馈信息。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的反馈信息，其中，下行参考信号的反馈信息包含下行信道估计的结果，当下行参考信号为CSI-RS时，该下行参考信号的反馈信息为信道状态信息报告(CSI-RS report)。
网络设备根据该下行参考信号的反馈信息获得下行信道估计的结果以及上行信道估计的结果。
本申请实施例中，终端设备在设备内部过热情况下，向网络设备发送第一过热指示信息，第一过热 指示信息用于指示当前终端设备需要不支持SRS天线轮发能力，网络设备根据第一过热指示信息生成第一重配置信息，终端设备根据第一重配置信息不支持SRS天线轮发能力。终端设备在不支持SRS天线轮发能力后，降低了终端设备的功耗，有效的解决终端设备过热问题。在终端设备不支持SRS天线轮发能力后，网络设备还可以通过向终端设备发送下行参考信号，并接收下行参考信号的反馈信息，获得上行信道估计的结果以及下行信道估计的结果，保证的数据传输的准确性。
终端设备出现过热问题，向网络设备发送第一过热指示信息之后，网络设备向终端设备发送第一重配置信息，终端设备根据第一重配置信息不支持SRS天线轮发能力。在网络设备向终端设备发送第一重配置信息后，网络设备还可以向终端设备重新配置用于SRS轮发的SRS资源。为了便于理解，请参阅图6，图6为本申请实施例中过热指示方法的另一种实施例示意图。本申请实施例提供的另一种过热指示的方法包括：
601、网络设备向终端设备发送第一重配置信息。
本实施例中的内容与步骤501相似，此处不再赘述。
当网络设备向终端设备发送第一重配置信息之后，网络设备启动定时器，该定时器设定的时长称为第一时间间隔，第一时间间隔通常可以设置为：0.5秒、1秒、5秒、10秒、30秒或60秒等。
网络设备启动定时器后，网络设备可能遇到多种情况，下面分别描述：
在第一时间间隔内，网络设备接收到该终端设备发送的过热指示信息中，指示终端设备温度正常情况，执行步骤602；
在第一时间间隔内，网络设备接收到该终端设备发送的过热指示信息中，指示终端设备温度过热情况，执行步骤603；
在第一时间间隔内，网络设备没有接收到该终端设备发送的过热指示信息，执行步骤604。
602、终端设备向网络设备发送第二过热指示信息。
本实施例中，终端设备的温度恢复正常后，终端设备可以向网络设备发送过热指示信息，以告知网络设备当前终端设备温度已恢复正常，该过热指示信息称为第二过热指示信息。当终端设备向网络设备发送第二过热指示信息之后，执行步骤604。
603、终端设备向网络设备发送第三过热指示信息。
本实施例中，终端设备的温度仍然为过热状态时，终端设备可以向网络设备发送过热指示信息，以告知网络设备当前终端设备温度仍然为过热状态，该过热指示信息称为第三过热指示信息。当终端设备向网络设备发送第三过热指示信息之后，网络设备根据该第三过热指示信息，重置定时器。重置定时器后，网络设备执行的步骤与步骤601中网络设备启动定时器后类似，此处不再赘述。
604、网络设备向终端设备发送第二重配置信息。
本实施例中，网络设备已获知终端设备此时已经处于温度正常状态，因此网络设备可以向终端设备发送第二重配置信息，该第二重配置信息用以重新配置终端设备中，用于SRS天线轮发的SRS资源。终端设备根据该第二重配置信息重新配置SRS资源后，终端设备支持SRS天线轮发能力。
当第一过热指示信息中还携带有减少MIMO layer指示时，该第二重配置信息还可以重新调整终端设备中上行MIMO能力和/或下行MIMO能力(MIMO layer)。具体的，调整终端设备中上行MIMO能力为：调整终端设备中的发送天线数目以及发射射频链路数目；调整终端设备中下行MIMO能力为：调整终端设备中的接收天线以及接收射频链路数目。其中，调整发送天线数目或接收天线数目的情况为，降低MIMO layer指示所指示的降低值低于当前终端设备的天线数目，例如第一过热指示信息中的降低MIMO layer指示为从4layer降低至2layer时，终端设备根据该第二重配置信息将接收天线数目从2调整为 4。
本申请实施例中，终端设备在不支持SRS天线轮发能力之后，若终端设备已经从过热状态恢复为温度正常状态，则网络设备可以重新向终端设备配置用于SRS天线轮发的SRS资源。以保证温度恢复正常后的终端设备，可以及时恢复SRS天线轮发能力。
