具体实施方式
为使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请实施方式作进一步地详细描述。
首先,对本申请实施例中涉及的名词进行简单介绍:
非激活态的小数据传输(Small Data Transmission,SDT):
SDT是为处于非激活态的终端配置的一种数据传输方式。通过SDT,终端无需进入连接态,即可完成业务数据的传输,从而减小终端设备的功耗和开销。
示例性的,SDT包括:基于随机接入过程(两步/四步)的上行小数据传输,也可以是基于预配置资源(如CG type1)的上行小数据传输。本申请实施例主要针对的是基于随机接入过程(两步/四步)的上行小数据传输。
图1示出了本申请一个示例性实施例提供的通信系统的框图,该通信系统可以包括:接入网12和终端14。
接入网12中包括若干个网络设备120。网络设备120可以是基站,所述基站是一种部署在接入网中用以为终端提供无线通信功能的装置。基站可以包括各种形式的宏基站,微基站,中继站,接入点等等。在采用不同的无线接入技术的系统中,具备基站功能的设备的名称可能会有所不同,例如在LTE系统中,称为eNodeB或者eNB;在5G NR-U系统中,称为gNodeB或者gNB。随着通信技术的演进,“基站”这一描述可能会变化。为方便本申请实施例中,上述为终端14提供无线通信功能的装置统称为网络设备。
终端14可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备,以及各种形式的用户设备,移动台(Mobile Station, MS),终端(terminal device)等等。为方便描述,上面提到的设备统称为终端。网络设备120与终端14之间通过某种空口技术互相通信,例如Uu接口。可选地,终端处于RRC_INACTIVE态。
本申请实施例的技术方案可以应用于各种通信系统,例如:全球移动通讯(Global System of Mobile Communication,GSM)系统、码分多址(Code Division Multiple Access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统、通用分组无线业务(General Packet Radio Service,GPRS)、长期演进(Long Term Evolution,LTE)系统、LTE频分双工(Frequency Division Duplex,FDD)系统、LTE时分双工(Time Division Duplex,TDD)系统、先进的长期演进(Advanced Long Term Evolution,LTE-A)系统、新无线(New Radio,NR)系统、NR系统的演进系统、非授权频段上的LTE(LTE-based access to Unlicensed spectrum,LTE-U)系统、NR-U系统、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access,WiMAX)通信系统、无线局域网(Wireless Local Area Networks,WLAN)、无线保真(Wireless Fidelity,WiFi)、下一代通信系统或其他通信系统等。
通常来说,传统的通信系统支持的连接数有限,也易于实现,然而,随着通信技术的发展,移动通信系统将不仅支持传统的通信,还将支持例如,设备到设备(Device to Device,D2D)通信,机器到机器(Machine to Machine,M2M)通信,机器类型通信(Machine Type Communication,MTC),车辆间(Vehicle to Vehicle,V2V)通信以及车联网(Vehicle to Everything,V2X)系统等。本申请实施例也可以应用于这些通信系统。
在基于随机接入过程(两步/四步)的上行小数据传输中,终端在执行随机接入过程之前,需要根据当前信号质量的测量结果与网络设备配置的RSRP门限,选择合适的载波,比如SUL或NUL。由于SDT需要终端在非激活态传输用户数据,因此,执行SDT对信道质量的要求高于随机接入过程;同时,执行SDT的覆盖范围也可能小于各个载波的最大覆盖。本申请中提出了一种UE选择用于执行SDT的载波以及判断是否满足执行SDT的信道条件的方案。
图2示出了本申请一个示例性实施例提供的小数据传输方法的流程图。该方法可以应用于如图1示出的终端和网络设备中,终端处于非激活态,该方法包括:
步骤202:网络设备向终端配置第一RSRP门限;
第一RSRP门限是用于为小数据传输选择载波的RSRP门限。也即,第一RSRP门限是用于在小区提供的至少两个载波为小数据传输选择载波的RSRP门限。
在一些实施例中,第一RSRP门限相同于第二RSRP门限,第二RSRP门限是在随机接入过程中进行载波选择的RSRP门限。第一RSRP门限和第二RSRP门限共用同一配置过程。第二RSRP门限可认为是现有RSRP门限或传统RSRP门限。
在一些实施例中,第一RSRP门限不同于第二RSRP门限。第一RSRP门限和第二RSRP门限采用不同的配置过程。
步骤204:终端接收网络设备配置的第一RSRP门限;
步骤206:终端根据第一RSRP门限为小数据传输选择载波。
示意性的,终端的当前驻留小区的RSRP门限大于第一RSRP门限时,为小数据传输选择第一载波;终端的当前驻留小区的RSRP门限小于第一RSRP门限时,为小数据传输选择第二载波。
终端的当前驻留小区的RSRP门限等于第一RSRP门限时,为小数据传输选择第一载波或第二载波,本实施例以为小数据传输选择第一载波为例来举例说明。
综上所述,本实施例提供的方法,通过由网络设备向终端配置第一RSRP门限,该第一RSRP用于为SDT在至少两个载波中选择出用于SDT的载波,从而在小区提供有多个载波的情况下,基于第一RSRP门限选择出合理的载波进行SDT,实现了多载波场景下的SDT。

步骤304:终端接收网络设备配置的第二RSRP门限;
步骤306:终端将第二RSRP门限确定为第一RSRP门限;
步骤308:终端根据第一RSRP门限为小数据传输选择载波。
示意性的,终端的当前驻留小区的RSRP门限大于或等于第一RSRP门限时,为小数据传输选择第一载波,比如NUL载波;终端的当前驻留小区的RSRP门限小于第一RSRP门限时,为小数据传输选择第二载波,比如SUL载波。
示意性的,终端的当前驻留小区的RSRP门限大于第一RSRP门限时,为小数据传输选择第一载波,比如NUL载波;终端的当前驻留小区的RSRP门限小于或等于第一RSRP门限时,为小数据传输选择第二载波,比如SUL载波。
综上所述,本实施例提供的方法,由于第一RSRP门限与第二RSRP门限共用同一个配置过程,因此网络侧可以不修改或少修改现有流程,从而提高与已有通信协议的兼容性。
针对第一RSRP门限与第二RSRP门限不共用同一配置过程的情况:
图4示出了本申请另一个示例性实施例提供的小数据传输方法的流程图。该方法可以应用于如图1所示出的终端和网络设备中,终端处于非激活态,该方法包括:
步骤402:网络设备向终端配置第一RSRP门限,第一RSRP门限不同于第二RSRP门限;
在本实施例中,第二RSRP门限与第一RSRP门限使用不同的配置过程,比如,采用新增信息单元(InformationElement,IE)来配置第一RSRP门限。可选地,网络设备在配置第二RSRP门限后,再单独向终端配置第一RSRP门限;或者,网络设备在配置第一RSRP门限后,再单独向终端配置第二RSRP门限。
第一RSRP门限的配置方式包括如下至少之一:
·第一RSRP门限值;
网络设备直接向终端配置第一RSRP门限的门限值。

网络设备向终端配置补偿值和第二RSRP门限,两者可以分开配置,或同时配置。终端接收网络设备配置的补偿值和第二RSRP门限。终端计算补偿值和第二RSRP门限的和,作为第一RSRP门限。
在一些实施例中,第一RSRP门限大于第二RSRP门限。
步骤404:终端接收网络设备配置的第一RSRP门限;
在一些实施例中,终端接收网络设备直接配置的第一RSRP门限。
在一些实施例中,终端接收网络设备配置的第二RSRP门限和缩放因子,计算缩放因子和第二RSRP门限的乘积,作为第一RSRP门限。
在一些实施例中,终端接收网络设备配置的第二RSRP门限和补偿值,计算补偿值和第二RSRP门限的和,作为第一RSRP门限。
步骤406:终端根据第一RSRP门限为小数据传输选择载波。
示意性的,终端的当前驻留小区的RSRP门限大于或等于第一RSRP门限时,为小数据传输选择第一载波,比如NUL载波;终端的当前驻留小区的RSRP门限小于第一RSRP门限时,为小数据传输选择第二载波,比如SUL载波。
示意性的,终端的当前驻留小区的RSRP门限大于第一RSRP门限时,为小数据传输选择第一载波,比如NUL载波;终端的当前驻留小区的RSRP门限小于或等于第一RSRP门限时,为小数据传输选择第二载波,比如SUL载波。
综上所述,本实施例提供的方法,由于第一RSRP门限与第二RSRP门限分别使用各自的配置过程,因此网络侧可以配置比第二RSRP门限更高的第一RSRP门限,从而使得终端选择信道质量更好的载波进行SDT,提高SDT的传输可靠性。
上述第一RSRP门限可以包括:N个RSRP子门限,第i个RSRP子门限对应第i个数据量门限。N为大于1的整数,i为不大于N的整数。
图5示出了本申请另一个示例性实施例提供的小数据传输方法的流程图。该方法可以应用于如图1所示出的终端和网络设备中,终端处于非激活态,该方法包括:
步骤502:网络设备向终端配置N个RSRP子门限,第i个RSRP子门限对应第i个数据量门限;

示例性的,第一RSRP子门限>第二RSRP子门限…>第N RSRP子门限,第一数据量门限>第二数据量门限…>第N数据量门限。也即,N个RSRP子门限按照由大到小的顺序排列,N个数据量门限按照由大到小的顺序排列。或者,N个RSRP子门限按照由小到大的顺序排列,N个数据量门限按照由小到大的顺序排列。
可选地,网络设备向终端配置N个RSRP子门限和N个数据量门限。
步骤504:终端接收网络设备配置的N个RSRP子门限;
终端接收网络设备配置的N个RSRP子门限,以及N个数据量门限。在一些实施例中,N个数据量门限可以是预设值。
步骤506:若终端的待传输数据量小于第i个数据量门限,且终端的当前驻留小区的RSRP大于第i个RSRP子门限,则为小数据传输选择第一载波;
可选地,第一载波是NUL,第二载波是SUL。
步骤508:若终端的待传输数据量大于N个数据量门限中的每一个,或,终端的当前驻留小区的RSRP小于N个RSRP子门限中的每一个,则为小数据传输选择第二载波。
若待传输数据量小于等于第一RSRP子门限对应的第一数据量阈值,且当前驻留小区的RSRP大于或等于第一RSRP子门限,则终端选择在NUL上执行SDT;否则终端继续判断;
若待传输数据量小于等于第二RSRP子门限对应的第二数据量阈值,且当前驻留小区的RSRP大于或等于第二RSRP子门限,则终端选择在NUL上执行SDT;否则终端继续判断;
…;

可选地,终端还需要进一步判断是否满足其他执行SDT的条件。比如,其他执行SDT的条件包括:是否存在执行SDT的传输资源或时频资源。
若终端的当前驻留小区的RSRP大于或等于目标RSRP,且满足其他执行SDT的条件,则在基于第一RSRP门限所选择的载波上执行SDT;若终端的当前驻留小区的RSRP小于目标RSRP,或不满足其他执行SDT的条件,则不在基于第一RSRP门限所选择的载波上执行SDT。
需要说明的是:第一RSRP门限的判断过程、目标RSRP门限的判断过程、其它执行SDT的条件的判断过程可以分别进行,可以同时进行,也可以依次执行。
在依次执行上述三个判断过程时,可以先进行第一RSRP门限的判断过程、再进行目标RSRP门限的判断过程、最后进行其它执行SDT的条件的判断过程,也可以为其它顺序,本实施例不加以限定。
综上所述,本实施例提供的方法,还通过网络设备向终端配置目标RSRP门限,由终端根据目标RSRP门限,确定是否在基于第一RSRP门限所选择的载波上执行SDT,能够在较小的可用覆盖区域内实现可靠的SDT传输。

…;
若待传输数据量小于等于第NRSRP子门限对应的数据量阈值,且当前驻留小区的RSRP大于或等于第N RSRP子门限,则UE选择在NUL上执行SDT;否则UE选择在SUL上执行SDT;
可选的,若网络为UE配置了目标RSRP门限,且UE在步骤2中选择了SUL,则UE进一步对比当前驻留小区的RSRP与目标RSRP门限:
