具体实施方式
下面结合附图和实施例对本申请进行说明。可以理解的是，此处所描述的具体实施例仅仅用于解释本申请，而非对本申请的限定。需要说明的是，在不 冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。另外还需要说明的是，为了便于描述，附图中仅示出了与本申请相关的部分而非全部结构。
在长期演进技术升级版(Long Term Evolution-Advanced，LTE-A)的Release 10标准(LTE-A版本10)中，在上行通信中使用非预编码的SRS，即天线专有的SRS，而对物理上行共享信道(Physical Uplink Shared Channel，PUSCH)的用于解调的参考信号(Demodulation Reference Signal，DMRS)则进行预编码。第一通信节点通过接收非预编码的SRS，可估计出上行的原始CSI，而经过了预编码的DMRS则不能使第一通信节点估计出上行原始的CSI。这种情况下，当第二通信节点使用多天线发送非预编码的SRS时，所需要的SRS资源都会增加，造成***内可同时复用的第二通信节点数量下降。第二通信节点可通过高层信令(也称为通过trigger type 0触发)或下行控制信息(也称为通过trigger type 1触发)这两种触发方式发送SRS，基于高层信令触发的为周期SRS，基于下行控制信息(Downlink Control Information，DCI)触发的为非周期SRS。物理下行控制信道(Physical Downlink Control Channel，PDCCH)用于承载DCI，其中，DCI可包括上、下行调度信息，以及上行功率控制信息。在LTE-A Release 10中增加了非周期发送SRS的方式，一定程度上改善了SRS资源的利用率，提高资源调度的灵活性。
在新空口(New Radio，NR)的Realease15标准中，SRS的用途有多种，在这种情况下，相关技术中第一通信节点和第二通信节点之间关于SRS的信令配置和信号传输灵活性较差，无法保证在各种情况下都有效准确地进行信号传输，影响通信可靠性。例如，在SRS资源集的用途参数(usage)被配置为码本(codebook)或非码本的情况下，第一通信节点可以为第二通信节点配置两个SRS资源集，两个SRS资源集可能为周期的也可能为非周期的，这两个SRS资源集中的参数如何关联、如何配置，影响了信号的可靠传输。又如，在SRS资源集的用途参数被配置为码本或非码本的情况下，如果第一通信节点只为第二通信节点配置了周期的SRS资源集，而第一通信节点又想通过下行控制信息(Downlink Control Information，DCI)等触发第二通信节点发送非周期的SRS，这种情况下，周期的SRS资源集如何配置，影响到确定非周期SRS的发送时隙，也影响了信号的可靠传输。
本申请实施例中，第一通信节点是指网络侧、基站、服务节点等，例如演进型基站(e-Node-B，eNB)，可以通过下行控制信息配置第二通信节点设备，第二通信节点是指终端侧、用户设备(User Equipment)等，可以接受DCI控制或接受高层信令的配置。
图1为一实施例提供的一种传输方法的流程图，该传输方法可应用于第一通信节点。如图1所示，本实施例提供的方法包括步骤110和步骤120。
在步骤110中，配置探测参考信号SRS资源集，所述SRS资源集的用途为波束管理、码本、非码本或天线切换。
在步骤120中，接收第二通信节点根据所述SRS资源集发送的SRS。
探测参考信号(Sounding Reference Signal，简称为SRS)是一种第二通信节点设备与第一通信节点间用来测量无线信道信息(Channel State Information，CSI)的信号。在长期演进***中，第二通信节点按照第一通信节点指示的频带、频域位置、序列循环移位、周期和子帧偏置等参数，定时在发送子帧的最后一个数据符号上发送上行SRS。第一通信节点根据接收到的SRS判断UE上行的CSI，并根据得到的CSI进行频域选择调度、闭环功率控制等操作。
本实施例中，第一通信节点基于SRS资源集的用途配置SRS资源集，在此基础上，接收第二通信节点通过配置的SRS资源集发送的SRS，从而提高信号传输的灵活性和通信的可靠性。
在一实施例中，对于基于码本的传输或基于非码本的传输，所述SRS资源集包括第一资源集和第二资源集；所述第一资源集对应的资源类型为非周期资源、半持续资源或周期资源；所述第二资源集对应的资源类型为非周期资源、半持续资源或周期资源。
本实施例中，SRS资源集的用途参数(usage)被配置为码本或非码本，这种情况下，第一通信节点为第二通信节点配置两个SRS资源集，这两个SRS资源集对应的资源类型(resource type)分别可以为周期资源、半持续资源或周期资源中的任意一种。例如，第一通信节点为第二通信节点配置了SRS资源集0和SRS资源集1，SRS资源集0可以被配置为非周期资源，SRS资源集1可以被配置为周期资源。
在一实施例中，所述第一资源集和所述第二资源集对应的带宽或资源块位置相同；所述第一资源集和所述第二资源集的准共位(Quasi-Co-Location，QCL)关系为类型A、类型B、类型C和类型D中的至少一种。
例如，第一通信节点为第二通信节点配置了SRS资源集0和SRS资源集1，SRS资源集0被配置为非周期资源，SRS资源集1被配置为周期资源，SRS资源集0和SRS资源集1具有相同的带宽或者相同的资源块(Resource Block，RB)位置，且SRS资源集0和SRS资源集1具有QCL Type-A、QCL Type-B、QCL Type-C以及QCL Type-D关系中的一种或多种。
在一实施例中，所述第一资源集中配置的SRS资源的数量与所述第二资源 集中配置的SRS资源的数量相等；所述第一资源集中配置的一个时隙内的SRS资源的数量与所述第二资源集中配置的在对应时隙内的SRS资源的数量相等。例如，第一通信节点为第二通信节点配置了SRS资源集0和SRS资源集1，SRS资源集0中的SRS资源数量和SRS资源集1中的SRS资源数量相等，并且两个SRS资源集中对应时隙内的SRS资源数量也相等。
在一实施例中，所述第一资源集的空间关系信息(Spatial Relation Information)和所述第二资源集的空间关系信息相同。例如，第一通信节点为第二通信节点配置了SRS资源集0和SRS资源集1，SRS资源集0和SRS资源集1的空间关系信息相同。
在一实施例中，所述SRS资源集包括第一资源集，所述第一资源集的资源类型为周期资源。
本实施例中，在SRS资源集的用途参数被配置为码本的情况下，第一通信节点只为第二通信节点配置了一种资源集，即周期的SRS资源集，第一通信节点可以通过DCI中的SRS请求域触发第二通信节点发送非周期的SRS。第二通信节点检测到DCI中的SRS请求域后，可将周期SRS资源集当成非周期SRS资源集使用。
在一实施例中，还包括：通过下行控制信息的SRS请求域触发第二通信节点在目标时隙上发送非周期的SRS，其中，所述目标时隙为从参考时隙开始计数的第1个有效时隙，或者为从参考时隙开始计数的第k+1个有效时隙，k为0或正整数，或者为从参考时隙开始计数的第k个有效时隙，k为正整数；所述参考时隙为对n与第一参数的乘积向下取整的值所对应的时隙，n对应于触发非周期SRS的时隙，第一参数为2的μ SRS次幂与2的μ PDCCH次幂的比值，μ SRS为触发非周期SRS的子载波间隔配置；μ PDCCH为携带触发信息的PDCCH的子载波间隔配置。
本实施例中，假定UE在时隙n接收到触发非周期SRS的DCI，则UE发送非周期SRS的时隙的确定方式包括以下至少之一：
1)在从
Figure PCTCN2020126413-appb-000001
开始计数的第1个有效(valid)时隙发送非周期SRS资 源集，其中，μ SRS为触发的SRS的子载波间隔配置，μ PDCCH为携带触发信息的PDCCH的子载波间隔配置。
2)在从
Figure PCTCN2020126413-appb-000002
开始计数的第k+1个有效(valid)时隙发送非周期SRS资源集，其中，k为0或正整数。μ SRS为触发的SRS的子载波间隔配置，μ PDCCH为携带触发信息的PDCCH的子载波间隔配置，基于SRS请求域的状态可以确定k的取值。
表1为一实施例中的SRS请求域与k值的映射关系表。如表1所示，在SRS请求域为00的情况下，k值无效，不触发非周期SRS；在SRS请求域为01的情况下，k值为0，即从

开始计数的第1个有效(valid)时隙发送非周期SRS资源集。
在一实施例中，所述有效时隙包括以下至少之一：
时隙中有可获得的上行符号用于SRS资源集中全部的SRS资源发送，且满足触发非周期SRS的物理下行控制信道(Physical Downlink Control Channel，PDCCH)与所述SRS资源集中所有SRS资源发送之间的最小时间要求的时隙；
时隙中有可获得的上行符号用于SRS资源集中全部的SRS资源发送，且满足触发非周期SRS的PDCCH与所述SRS资源集中所有SRS发送之间的最小时间要求，且为除了周期SRS发送时隙以外的时隙。
本实施例中，如果一个时隙为有效时隙，则该时隙满足：该时隙中有可获得的上行符号能够用于发送SRS资源集中全部的SRS资源，并且该时隙能够满足触发非周期SRS的PDCCH与SRS资源集中所有SRS发送之间的最小时间要求；在一些实施例中，还满足：该时隙不是发送周期SRS的时隙。
在一实施例中，所述第一资源集配置的功率控制参数和所述第二资源集配置的功率控制参数相同；所述功率控制参数包括：发送功率、路损补偿和路径损耗。
本实施例中，对于基于码本的传输或基于非码本的传输，在SRS的用途参数被配置为码本或非码本的情况下，第一通信节点为第二通信节点配置两个SRS资源集，这两个SRS资源集对应的资源类型分别可以为周期资源、半持续资源或周期资源中的任意一种。例如，第一通信节点为第二通信节点配置了SRS资源集0和SRS资源集1，SRS资源集0可以被配置为非周期资源，SRS资源集1可以被配置为周期资源。SRS资源集0和SRS资源集1对应的功率控制参数相同，功率控制参数包括SRS信号的发送功率(alpha)、路损补偿(p0)和路径损耗(pathlossReferenceRS)。
本实施例中，UE期望周期SRS资源集和非周期SRS资源集中的功率控制参数都配置为相同的值。
在一实施例中，所述第一资源集的发送功率与所述第二资源集的发送功率的差值为预设值，或者由第一通信节点通过无线资源控制信令配置。
本实施例中，第一资源集的发送功率与所述第二资源集的发送功率的差值为预设值。例如，第一通信节点为第二通信节点配置了SRS资源集0和SRS资源集1，SRS资源集0可以被配置为非周期资源，SRS资源集1可以被配置为周期资源。周期SRS资源集的发送功率与非周期SRS资源集的发送功率之间相差M dBm，其中，M为一预定义的数值，或者由基站通过RRC信令配置。
在一实施例中，还包括：在第一资源集对应的资源类型为周期资源且第二资源集对应的资源类型为非周期资源的情况下，通过PDCCH中的调度请求指示域指示第二通信节点从最近的资源集中确定SRS资源，其中，所述最近的资源集为距离所述PDCCH所在时隙最近的第一资源集或第二资源集。
本实施例中，在SRS的用途参数被配置为码本或非码本的情况下，第一通信节点为第二通信节点配置两个SRS资源集，例如分别配置为周期SRS资源集和非周期SRS资源集，则通过PDCCH中的调度请求指示(Schduling Request Indication，SRI)域用于指示从最近的(latest)SRS资源集中选择出1个SRS资源，其中，最近的SRS资源集为距离携带SRI域的PDCCH所在时隙最近的周期SRS资源集或非周期SRS资源集。

本实施例中，在SRS资源集为周期资源和/或半持续资源的情况下，配置了SRS资源集的参数，用于表示资源集中SRS资源的资源类型和触发状态。例如，SRS资源集1中参数aperiodicSRS-ResourceTrigger配置为“01”，如果DCI中的SRS请求域的状态为01，则表示此SRS资源集1被触发或被选中，从而指示第二通信节点使用该SRS资源集发送SRS；如果其他SRS资源集中的参数aperiodicSRS-ResourceTrigger的状态为非“01”，则表示不发送其他SRS资源集。即在SRS资源集中的aperiodicSRS-ResourceTrigger的状态与DCI中的SRS请求域的状态相同的情况下，第二通信节点才会发送此SRS资源集。
在一实施例中，还包括：在配置多个SRS资源集且所述多个SRS资源集的资源类型都为周期资源的情况下，通过下行控制信息或介质访问控制层控制单元(Medium Access Control Control Element，MAC CE)信令指示第二通信节点选择出一个SRS资源集，并停止或取消其他SRS资源集的发送。
本实施例中，第一通信节点为第二通信节点配置多个SRS资源集，所述多个SRS资源集的资源类型都为周期的。此外，第一通信节点通过DCI或者介质访问控制控制单元MAC CE信令指示第二通信节点从所述多个SRS资源集中选择出一个SRS资源集，用于SRS的发送，并且，停止其他未选中的SRS资源集对应的周期SRS发送，从而可以根据信道变化的快慢，动态调整周期SRS的周期大小。例如当信道变化快时，则选择周期小的SRS资源集；当信道变化慢时，则选择周期大的SRS资源集。
在一实施例中，在SRS资源集或SRS资源中配置多个SRS周期，第一通信节点通过DCI或者介质访问控制控制单元MAC CE信令指示第二通信节点从所述多个SRS周期中选择出一个，用于SRS的发送，同时，停止其他未选中的SRS周期的发送。
另外，在SRS资源集包含多个SRS资源的情况下，第二通信节点不期望所述多个SRS资源的周期不相同，即，期望所述多个SRS资源配置为相同的周期。
