参见图1，是本发明实施例提供一种探测参考信号SRS的传输方法的流程 示意图，如图所示的方法可包括以下步骤：
步骤S101、基站在系统带宽划分至少一个配置带宽，并分别为所述至少一个配置带宽中的每个配置带宽配置对应的SRS参数集信息；所述SRS参数集信息用于确定终端发送SRS的方式。
本发明实施例中，基站根据不同业务数据对应的关键性能指标KPI将系统带宽划分为一个或多个配置带宽。基站还可根据不同业务数据对应的关键性能指标KPI分别为所述至少一个配置带宽中的每个配置带宽配置对应的SRS参数集信息。
5G中存在有多种垂直业务场景，其包括以下中的一项或多项：移动宽带增强(enhanced Mobile Broadband，eMBB)、超高可靠超低时延通信(Ultra-Reliable Low-Latency Communications，URLLC)、大规模物联网(massive Machine Type Communications，mMTC)、或者其他应用场景。不同的业务场景对应不同的业务数据，不同业务场景下的关键性能指标(Key Performance Indicator，KPI)可不同，也即是不同的业务数据可对应不同的KPI。
同一种业务场景下，终端所支持的业务的类型可以相同，也可不同。不同的业务(或业务的类型)可对应不同的KPI。也即是，针对于同一个业务场景，也会有不同的KPI，其适用于不同类型的业务。
举例来说，在URLLC业务场景下，其所支持的具体业务类型可包括车联网业务、工业控制业务、远程医疗业务等等，这些业务可对应不同的KPI。例如针对车联网业务，其KPI更关注是可靠性；针对工业控制业务，其KPI更关注的是可靠性和时延；针对远程医疗业务，其KPI更关注的是数据量和可靠性。此时基站可为车联网业务、工业控制业务及远程医疗业务划分的配置带宽分别为配置带宽1、配置带宽1和配置带宽3，配置带宽1<配置带宽2<配置带宽3。同时，基站还可根据这三种业务对应的KPI，为三个配置带宽(配置带宽1、2、3)分别配置对应的SRS参数集信息，如子载波间隔和符号长度。分别如下：车联网业务对应的子载波间隔1<工业控制业务对应的子载波间隔2<远程医疗业务对应的子载波间隔3，车联网业务对应的符号长度1>工业控制业务对应的符号长度2>远程医疗业务对应的符号长度3。
在一些实施例中，基站还可根据服务小区内的终端的数量和不同业务数据 对应的KPI将系统带宽划分为至少一个配置带宽。
在本发明的一个实施例中，若所述终端支持传输第一业务数据的数量为第一数量，则所述配置带宽为第一配置带宽，所述第一配置带宽用于传输所述第一业务数据；若所述终端支持传输第二业务数据的数量为第二数量，则所述配置带宽为第二配置带宽，所述第二配置带宽用于传输所述第二业务数据；其中，所述第一数量大于所述第二数量，第一业务数据对应的KPI指标与第二业务数据对应的KPI指标不同，则所述第一配置带宽大于所述第二配置带宽。
举例来说，若基站当前服务小区内有100个用户终端，其中70个用户终端在第一传输业务数据时对时延KPI有要求，其余30个用户终端在传输第二业务数据时对可靠性KPI有要求。那么，此时基站可为第一业务数据划分的配置带宽为第一配置带宽，为第二业务数据划分的配置带宽为第二配置带宽，其中第一配置带宽大于第二配置带宽。例如，在系统带宽为100MHZ(兆赫兹)的情况下，基站可为第一业务数据划分的配置带宽为80M，基站为第二业务数据划分的配置带宽为20MHZ。也即是基站划分80M带宽用于传输第一业务数据，划分30M带宽用于传输第二业务数据，第一业务数据对应的KPI指标为时延，第二业务数据对应的KPI指标为可靠性。
在一些实施例中，请参见图2，是本发明实施例提供的一种配置带宽划分的示意图。由图可知，基站可将该基站支持的系统带宽(例如100MHz)划分为N个配置带宽，每个配置带宽互不重叠，且每个配置带宽的频带宽度也可不同。
在一些实施例中，基站还可实时或周期性地根据不同业务数据对应的KPI来更新或重新划分各个配置带宽。
在一些实施例中，所述至少一个配置带宽中的每个配置带宽所支持的业务的类型可以相同，也可不同。即所述至少一个配置带宽中的每个配置带宽可用于传输不同类型的业务数据，也可用于传输相同类型的业务数据。所述至少一个配置带宽中的每个配置带宽所对应的频带宽度可以相同，也可不同。但所述至少一个配置带宽中的每个配置带宽所占用的频域资源互不重叠，也即是所述每个配置带宽在所述系统带宽上占用不同的频域资源或频率带宽。
在本发明的又一个实施例中，所述SRS参数集信息包括子载波间隔和符 号长度；若所述终端传输第一业务数据对应的KPI指标为第一指标，则与所述第一业务数据对应的第一SRS参数集信息中的子载波间隔为第一子载波间隔且所述第一SRS参数集信息中的符号长度为第一符号长度，与所述第一SRS参数集信息对应的第一配置带宽用于传输所述第一业务数据；若所述终端传输第二业务数据对应的KPI指标为第二指标，则与所述第二业务数据对应的第二SRS参数集信息中的子载波间隔为第二子载波间隔且所述第二SRS参数集信息中的符号长度为第二符号长度，与所述第二SRS参数集信息对应的第二配置带宽用于传输所述第二业务数据；其中，所述第一指标高于所述第二指标，则所述第一子载波间隔大于所述第二子载波间隔且所述第一符号长度小于所述第二符号长度。
举例来说，在无人驾驶场景下，如汽车控制命令等业务数据对可靠性及时延KPI要求较高(例如传输时延不超过1ms)，此时基站可为此类时延KPI要求较高的业务数据对应配置/绑定的SRS参数集信息可为第一SRS参数集信息，该第一SRS参数集信息可包括第一子载波间隔(如60KHZ、120KHZ等)、第一符号长度(如16.67us，8.3us)等信息。针对诸如视频数据、语音数据等对及时性或时延要求不高(例如传输时延不超过10ms)的业务数据，此时基站可为此类业务数据对应配置/绑定的SRS参数集信息可为第二SRS参数集信息，该第二SRS参数集信息可包括第二子载波间隔(例如15kHZ、60KHZ等)、第二符号长度(例如66.67us，16.67us)等信息。其中，第一子载波间隔大于第二子载波间隔，第一符号长度小于第二符号长度。
在一些实施例中，所述配置带宽的频宽为所述子载波间隔的正整数倍。也即是多个子载波间隔在频域资源上可以拼接成所述配置带宽。
关于针对SRS参数集信息用于确定终端发送SRS的方式的理解，可具体参见如图3所示，是本发明实施例提供的一种终端在符号N上发送SRS的示意图。由图3可知，SRS参数集信息采用不同的子载波间隔，其符号长度也不同。如图3中竖线网格的配置带宽上采用15kHZ的子载波间隔进行SRS的传输；横线网格的配置带宽上采用30kHZ的子载波间隔进行SRS的传输。由图还可知，竖线网格的配置带宽和横线网格的配置带宽上对应的符号长度为2:1，也即是终端在竖线网格的配置带宽上以一个符号长度的时间向基站发送SRS， 然而终端在横线网格的配置带宽上以0.5个符号长度的时间向基站发送SRS。
需要说明的是，上述符号N仅仅为示例不构成限定。这里的符号N可以是符号1、符号2…也可以是数据子帧的最后一个符号，由于符号N是现有技术，这里不做详述。
步骤S102、所述基站确定所述终端发送SRS对应的目标配置带宽。
在步骤S102的一种具体实施方式中，所述基站可根据所述终端支持的业务的类型，来确定所述终端发送SRS对应的目标配置带宽。
具体的，由于上述基站是根据各终端支持的业务数据对应的KPI来划分的配置带宽。可知，针对每个终端而言，基站可根据该终端所支持的业务数据对应的KPI确定出该终端发送SRS对应的目标配置带宽，所述目标配置带宽为所述至少一个配置带宽中的带宽。
在步骤S102的又一种具体实施方式中，所述基站可根据所述终端支持的工作频段，来确定所述终端发送SRS对应的目标配置带宽。
具体的，由于不同厂商出厂的终端，其对应设置的工作频段可以不同；或者，不同终端的射频模块(例如WIFI、SIM卡)可使用不同的工作频段进行连网通信。例如，移动终端可支持1880-1900MHz(兆赫兹)和2010-2025MHz两个频段对应的配置带宽、联通终端可支持1940-1955MHz和2130-2145MHz两个频段对应的配置带宽、电信终端可支持1920-1935MHz和2110-2125MHz两个频段对应的配置带宽。
需要说明的是，所述目标配置带宽为所述至少一个配置带宽中的带宽，所述目标配置带宽为基站确定出的终端发送SRS所占用的带宽，也即是确定所述终端发送SRS的方式。
在一些实施例中，所述基站还可以为所述终端发送SRS配置相应地发送参数。这里的发送参数同样用于确定所述终端发送SRS的方式。所述发送参数和所述SRS参数集信息包括两个维度上用于确定所述终端发送SRS的方式的参数信息。所述发送参数可包括所述目标配置带宽的标识、传输带宽类型(如全带宽)、周期或非周期发送、SRS的发送周期(或SRS的发送时间)、多址方式(例如频分多址、码分多址等)、或者其他用于影响终端发送SRS的一些参数信息。
在一些实施例中，所述传输带宽类型可包括全带宽、半带宽、1/4带宽、及1/2n带宽等等，其中n为正整数。关于上述多址方式是指在同一个配置带宽内，支持多个终端采用频分多址和/或码分多址的方式实现多用户终端的SRS复用，所述多址方式属于现有技术，这里不做详述。
步骤S103、向所述终端发送SRS配置信息，所述SRS配置信息包括所述至少一个配置带宽中的每个配置带宽对应的SRS参数集信息和所述目标配置带宽的标识，所述SRS配置信息用于所述终端按照所述目标配置带宽对应的发送SRS的方式在所述目标配置带宽上向所述基站发送所述SRS。
本发明实施例中，在基站为所述终端配置完用于发送SRS的一些参数后(如发送参数和SRS参数集信息)，基站可向所述终端发送SRS配置信息。其中，所述SRS配置信息可包括所述至少一个配置带宽中的每个配置带宽对应的SRS参数集信息和所述目标配置带宽的标识。
具体的，基站可以广播消息或公共控制信息的形式将所述SRS配置信息或所述至少一个配置带宽中的每个配置带宽对应的SRS参数集信息发送给所述终端。也即是基站可通过广播信道(Broadcast Channel，BCH)或控制信道(Control Channel，CCH)将所述SRS配置信息发送给所述终端。
在一些实施例中，所述目标配置带宽的标识用于标识所述目标配置带宽的频域资源，所述目标配置带宽的标识可包括所述目标配置带宽的索引，如配置带宽1、所述目标配置带宽的名称、所述目标配置带宽的宽度、所述目标配置带宽的起始频域位置等等。
在一些实施例中，所述SRS配置信息还包括上述的发送参数，如传输带宽类型、发送周期及多址方式等等参数信息。
在一些实施例中，为实现每个终端在整个配置带宽或系统带宽的SRS上报，对于不同的SRS符号可采用跳频方式进行传输，也即是按照一定的顺序在配置带宽上进行跳频。请参见图4，是本发明实施例提供的一种配置带宽间的SRS跳频示意图。图4所示给出4种SRS跳频发送方式，其中白色网格、灰色网格、竖线网格和横线网格分别代表在配置带宽1、配置带宽2、配置带宽3及配置带宽N中进行SRS跳频发送的示意图。其中，SRS符号1、SRS符号2以及SRS符号N可以理解为时间域概念中的不同时间点。
在一些实施例中，所述SRS用于估计上行信道的频域信息，做频率选择性调度，也可用于估计上行信道，做下行波束赋形。在本发明实施例中，所述SRS可用于对所述目标配置带宽进行相应地带宽(或信道)检测和评估。
在一些实施例中，所述基站还可为终端配置所述终端在不同配置带宽间进行跳频SRS发送的方式。如在所述基站确定到发送SRS所占用的目标配置带宽(即确定到发送SRS所对应采用的SRS参数集信息)后，所述基站可将除去所述目标配置带宽之外的系统带宽按照所述目标配置带宽的频带宽度进行重新划分，得到至少一个跳频带宽。所述基站还可将所述至少一个跳频带宽的标识携带在所述SRS配置信息中发送给所述终端。所述SRS配置信息还可用于指示所述终端按照所述至少一个跳频带宽的标识的顺序，及所述目标配置带宽对应发送SRS的方式在各个跳频带宽间进行SRS的跳频发送。所述至少一个跳频带宽的标识可以是顺序或乱序排列并携带在所述SRS配置信息中。
在一些实施例中，所述至少一个跳频带宽为所述基站根据所述目标配置带宽的频带宽度对所述系统带宽进行重新划分得到的。也即是，在所述基站确定到终端发送SRS占用的目标配置带宽(即确定到所述目标配置带宽对应的发送SRS的方式)后，所述基站可按照所述目标配置带宽的频带宽度对所述系统带宽进行等分，得到至少一个跳频带宽。
举例来说，假设基站根据不同业务数据对应的KPI将100MHz的系统带宽划分为三个频带宽度分别为20MHz、40MHz和40MHz的配置带宽，且为这三个配置带宽分别配置的子载波间隔为15KHz、30KHz和60KHz。基站为用户终端A配置其占有20MHz的配置带宽1来发送全带宽的SRS。由于基站想要终端在系统带宽内均发送SRS，以对系统带宽进行全频带的信道检测，则基站可根据配置带宽1(20MHz)的频带宽度，将系统带宽100MHz重新按照频带宽度20MHz进行等分，得到5个跳频带宽，分别为跳频带宽1至5。进一步地，基站还可自主为所述用户终端A配置在各个跳频带宽进行跳频发送SRS的顺序，如顺序跳频为跳频带宽1、跳频带宽2…跳频带宽5，或乱序跳频为跳频带宽1、跳频带宽3、跳频带宽4…跳频带宽5、跳频带宽2等。
需要说明的是，所述目标配置带宽为所述终端首次发送SRS所占用的带宽，其后再按照所述至少一个跳频带宽的标识的顺序，及所述目标配置带宽对 应发送SRS的方式(如子载波间隔、符号长度)在所述至少一个跳频带宽上发送SRS。
在一些实施例中，所述基站还可为终端配置所述终端在同一配置带宽内进行跳频SRS发送的方式。如在所述基站确定到发送SRS所占用的目标配置带宽(即确定到发送SRS所对应采用的SRS参数集信息)后，所述基站可根据当前在所述目标配置带宽内进行业务数据传输的终端数量，来配置所述终端在同一配置带宽内进行跳频SRS发送的方式。例如，有5个用户终端在每个子帧的符号N上占用配置带宽1均需发送SRS，此时可将配置频带1至少等分为5份，这里假设等分5份，得到5个跳频子带宽，分别为跳频子带宽1至5。若要完成整个配置带宽1的信道检测，则基站需要为这5个用户终端配置在配置带宽1内进行SRS的跳频发送方式为：用户终端按照设定带宽内的跳频顺序(如跳频子带宽1至5)，及以配置带宽1对应的SRS发送方式在配置带宽1内进行SRS的跳频发送。不同用户终端在同一子帧符号N上占用不同的跳频子带宽发送SRS，这样每个用户终端在5个跳频子带宽内跳频发送SRS后，即可完成配置带宽1的信道检测。
在一些实施例中，所述目标配置带宽可包括至少一个跳频子带宽，所述基站可将所述至少一个跳频子带宽的标识携带在所述SRS配置信息中发送给所述终端，以便指示所述终端按照所述至少一个跳频子带宽的标识的顺序及所述目标配置带宽对应的发送SRS的方式依次向所述基站发送SRS。所述至少一个跳频子带宽的标识的顺序可以是顺序的，也可以是乱序的，这里不做限定。
在一些实施例中，所述跳频带宽也可包括至少一个跳频子带宽，所述基站可将所述至少一个跳频子带宽的标识携带在所述SRS配置信息中发送给所述终端，以便指示所述终端按照所述至少一个跳频子带宽的标识的顺序及所述目标配置带宽对应的发送SRS的方式依次在所述跳频带宽内向所述基站发送SRS。所述至少一个跳频子带宽的标识的顺序可以是顺序的，也可以是乱序的，这里不做限定。
即是，基站可以为所述终端配置所述目标配置带宽内的SRS跳频发送，也可为所述终端配置所述跳频带宽内的SRS跳频发送。
步骤S104、所述终端接收所述基站发送的SRS配置信息。
步骤S105、所述终端按照所述目标配置带宽对应的发送SRS的方式在所述目标配置带宽上向所述基站发送所述SRS。
在本发明的一个实施例中，所述终端接收到所述SRS配置信息，所述SRS配置信息可包括所述至少一个配置带宽中的每个配置带宽对应的SRS参数集信息和所述终端发送SRS对应的目标配置带宽的标识。接着，所述终端可根据所述至少一个配置带宽中的每个配置带宽对应的SRS参数集信息和所述目标配置带宽的标识，确定出与所述目标配置带宽对应的目标SRS参数集信息，所述目标SRS参数集信息可包括子载波间隔和符号长度。最后，所述终端可根据所述目标SRS参数集信息对应的方式(如以15KHz的子载波间隔、66.67us的符号长度等参数)在所述目标配置带宽上向基站发送SRS。
在本发明的又一个实施例中，所述SRS配置信息还包括所述终端发送SRS对应的至少一个跳频带宽的标识；所述在所述目标配置带宽上向所述基站发送所述SRS之后，还包括：所述终端按照所述至少一个跳频带宽的标识的顺序及所述目标配置带宽对应的发送SRS的方式依次向所述基站发送SRS，所述跳频带宽和所述目标配置带宽具有相同的频带宽度。
具体的，所述终端在按照所述目标配置带宽对应的发送SRS的方式在所述目标配置带宽上发送SRS后，所述终端可继续按照所述至少一个跳频带宽的标识的顺序、及所述目标配置带宽对应的发送SRS的方式依次在所述至少一个跳频带宽上向所述基站发送SRS。具体可参见前述实施例中的相关具体描述，这里不再赘述。
在一定程度上可以理解为：终端按照所述至少一个跳频带宽的标识的顺序(设定跳频顺序)及所述目标配置带宽对应发送SRS的方式在所述至少一个跳频带宽(即目标配置带宽)上发送SRS。也即是所述目标配置带宽按照所述至少一个跳频带宽的标识的顺序(设定跳频顺序)进行位置移动，以实现SRS的跳频发送。
在一些实施例中，所述至少一个跳频带宽为所述基站根据所述目标配置带宽的频带宽度对所述系统带宽进行重新划分得到的，所述跳频带宽具有和所述目标配置带宽相同的频带宽度。具体可参见前述实施例的相关描述，这里不再赘述。
举例来说，假设基站支持的系统带宽为100MHZ，基站根据当前小区实际情况将系统带宽分为5个配置带宽，分别为配置带宽1至配置带宽5，且每个配置带宽均占用20MHZ。假设当前基站的服务小区内存在两个用户终端分别为终端1和终端2。其中终端1占用系统带宽的其中60MHZ频带资源进行相关业务传输，终端2占用系统带宽其中的20MHZ频带资源进行相关业务传输。
目前，基站为终端2配置SRS发送方式包括：在配置带宽5上进行全带宽SRS的发送。由于终端2仅使用20MHZ的频域资源，终端利用上述SRS发送方式即可实现全频段20MHZ的信道评估，不用再进行SRS的跳频发送。
基站为终端1配置SRS发送方式包括：以5ms(毫秒)的SRS发送周期，占用配置带宽1进行全带宽的SRS发送。由于终端1需要对其使用的频域资源60MHz进行全频段的信道检测，因此基站还需为终端配置SRS的跳频发送方式。具体的，基站将60MHz的频带资源划分为跳频带宽1-3，每个跳频带宽的频带宽度为20MHz，基站为终端配置的SRS跳频发送方式可为：按照设定跳频顺序(如跳频带宽1至3)在对应的目标跳频带宽上进行SRS的跳频发送。上述终端1在跳频带宽1至3的跳频顺序可以是变化的，根据实际基站配置决定，例如可以按照跳频带宽1、跳频带宽2及跳频带宽3的顺序，或按照跳频带宽2、跳频带宽3及跳频带宽1的顺序等进行60MHZ的全频段的信道评估。
在一些实施例中，所述目标配置带宽及跳频带宽可包括至少一个跳频子带宽，所述SRS配置信息还包括所述至少一个跳频子带宽的标识；所述终端按照所述至少一个跳频子带宽的标识的顺序及所述目标配置带宽对应的发送SRS的方式依次向所述基站发送SRS，包括：所述终端按照所述至少一个跳频子带宽的标识的顺序及所述目标配置带宽对应的发送SRS的方式依次向所述基站发送SRS。
也即是，所述终端可以按照所述目标配置带宽对应的发送SRS的方式，及所述至少一个跳频子带宽的标识的顺序依次在所述跳频带宽内向所述基站发送SRS。在一些实施例中，所述终端可按照在所述目标配置带宽内进行SRS跳频的发送方式，在后续至少一个跳频带宽内进行相同方式的SRS跳频发送。
需要说明的是，所述终端按照基站为所述终端配置的SRS发送的方式， 既可实现配置带宽内的SRS跳频发送，也可实现配置带宽间的SRS跳频发送。
为帮助人们对上述实施例的详细理解，下面通过两个例子进行详细阐述。若基站支持的系统带宽(或小区带宽)为100MHz，基站根据不同业务数据对应的KPI指标静态将系统带宽划分为5个配置带宽，具体如图5所示。由图可知5个配置带宽分别为：配置带宽1、配置带宽2、配置带宽3、配置带宽4和配置带宽5，其中每个配置带宽均占20MHZ的频带宽度。根据各个终端支持的业务数据对应的KPI，为配置带宽1至3配置的SRS参数集信息包括子载波间隔为15KHz、为配置带宽4配置的SRS参数集信息包括子载波间隔为30KHz、为配置带宽5配置的SRS参数集信息包括子载波间隔为60KHz。其对应SRS参数集信息中的符号长度之比分别为4:2:1，具体可参见如图5所示。可选地，基站可通过公共控制信息将上述配置(即5个配置带宽、和5个配置带宽对应配置的SRS参数集信息，子载波间隔和符号长度)通知给终端。
实施例一：针对用户终端1，基站为其还配置有相关的发送参数，该发送参数用于确定发送SRS的方式，分别包括：SRS发送周期为5ms、在相应数据子帧的符号N上占用配置带宽1。为完成整个系统的SRS信道检测，基站可按照配置带宽1的频带宽度(20MHz)对系统带宽进行重新划分，得到5个跳频带宽，分别为跳频带宽1至跳频带宽5。基站还为用户终端1配置有相应地发送参数，可包括：按照跳频带宽1至跳频带宽5的设定跳频顺序依次进行全带宽的SRS跳频发送。针对用户终端2，基站为其配置用于确定发送SRS的方式的发送参数包括：SRS发送周期为5ms、在相应数据子帧的符号N上占用配置带宽4，同理还包括：按照跳频带宽4、跳频带宽5、跳频带宽1至跳频带宽3的设定跳频顺序依次进行半带宽的SRS跳频发送。
相应地，基站可以将上述相关发送参数通知给对应的用户终端，这里即用户终端1和用户终端2。在用户终端接收相关发送参数和公共控制信息后，可根据所述相关发送参数和公共控制信息所对应的SRS发送方式，向基站发送SRS，具体可参见图6所示，是本发明实施例提供的一种终端SRS发送示意图。这里的用户终端1和用户终端2均位于所述基站的服务小区内。
需要说明的是，假设每个子帧长度为1ms，这里发送周期5ms是指每隔五个子帧发送一次SRS，例如第一个子帧的符号N发送SRS后，待到第六个子 帧的符号N发送SRS。另外，由于各个配置带宽的符号长度不同，不同配置带宽内的用户终端将使用不同数量的符号来发SRS。例如，15kHz子载波的配置带宽1-3是采用一个符号发送SRS。而对于30khz子载波的配置带宽4内的用户终端而言，一个周期内可以采用两个符号来发送SRS，如图6中的用户终端2使用两个符号来发的。同样的，60khz子载波的配置带宽5的用户终端则可以用4个符号来发送SRS。
由图6可知，灰色网格表示用户终端1的SRS发送，竖线网格表示用户终端2的SRS发送。用户终端1和用户终端2需花销20ms的时长来完成整个系统带宽的检测，也即是完成整个系统带宽上的SRS发送。其中，用户终端1以全带宽的方式按照设定跳频顺序依次在跳频带宽1至跳频带宽5上完成SRS的跳频发送。且在跳频带宽1至跳频带宽5上均按照为配置带宽1对应配置的SRS参数集信息(如子载波间隔15KHz)所对应的方式进行SRS的跳频发送。
用户终端2以半带宽的方式按照设定跳频顺序依次在跳频带宽4、跳频带宽5、跳频带宽1至跳频带宽3上完成SRS的跳频发送。且按照为配置带宽4对应配置的SRS参数集信息(如子载波间隔30KHz)所对应的方式进行SRS的跳频发送。
实施例二：基站除了为上述实施例一中用户终端1和用户终端2配置有发送参数之外，还为用户终端3配置有用于确定发送SRS的方式的发送参数包括：SRS发送周期为5ms、在每个数据子帧的符号N上占用配置带宽4，同理还配置有需按照跳频带宽4、跳频带宽5、跳频带宽1至跳频带宽3上的设定跳频顺序依次进行1/4带宽的SRS跳频发送。
参考前述相关内容描述可知，各个用户终端在接收到各自终端对应的发送参数和公共控制信息后，按照所述发送参数和公共控制信息所对应的SRS发送的方式向所述基站发送SRS。具体可参见图7所示，是本发明实施例提供的又一种终端发送SRS的示意图。这里的用户终端1、用户终端2和用户终端3均位于所述基站的服务小区内。
由图7可知，灰色网格表示用户终端1的SRS发送，竖线网格表示用户终端2的SRS发送，横线网格表示用户终端3的SRS发送。其中，用户终端 1和用户终端2需花销20ms的时长完成整个系统带宽的检测，用户终端3需花销45ms的时长来完成整个系统带宽的检测，也即是完成整个系统带宽上的SRS发送。
此外，用户终端3以1/4带宽的方式按照设定跳频顺序依次在跳频带宽4、跳频带宽5、跳频带宽1至跳频带宽3上完成SRS的跳频发送。且按照为配置带宽4对应配置的SRS参数集信息(如子载波间隔30KHz)所对应的方式进行SRS的跳频发送。关于用户终端1和用户终端2的SRS跳频发送请参见前述实施例一的相关具体描述，这里不再赘述。
需要说明的是，由图7可知用户2和用户3在同一周期内均用两个符号来发SRS，区别仅在于：用户2每个符号发1/2带宽，用户3每个符号发1/4带宽。
此外，基站可为用户终端3配置有在同一配置带宽内的SRS跳频发送方式。具体可参见图7中，用户终端3在不同配置带宽内发送SRS时，前五个周期所占的频带位置与后五个周期所占的频带位置是不同的，这样才能完成整个带宽的SRS覆盖。
通过实施本发明实施例，能够支持5G中不同业务场景下的SRS发送，提升SRS发送的完整性和灵活性。
