Description

终端能力的传输方法、装置和系统 技术领域
本申请涉及通信领域。
背景技术
实现工业物联网是5G的重要目标之一，在大规模工业无线传感器网络(IWSN)应用场景中，除了需要应用一些像URLLC这种高端能力的终端设备，更多的情况下只需要中低端能力的终端设备，包括温度湿度传感器、压力传感器、加速器、运动传感器等。另外，在另一个5G的垂直行业应用场景智慧城市中，广泛部署视频监控摄像机是一个重要的应用，监控摄像头也无需采用Rel-15/Rel-16这样的高端终端设备。还有大量的可穿戴设备，例如智能手表、手环、可穿戴医学监测设备等，对终端设备的处理能力要求也较低。
以上这些需要广泛应用的设备的性能比Rel-15/Rel-16终端设备更低，但是要高于LPWA设备(NB-IoT和LTE-M)，这些设备的基本特征包括：相较于URLLC和eMBB设备更低的复杂度、紧凑的结构和更小的设备尺寸、电池使用时间可持续到一年以上等。但现有的Rel-15/16 5G系统并不能很好地支持这种能力较低的终端设备，因此目前5G终端设备的成本普遍较高。
为了实现对中低端NR设备的支持，降低5G终端设备的成本，3GPP在Rel-17中开始了针对能力降低UE的研究项目，该研究的目的是明确相对于Rel-16的eMBB和URLLC NR设备，能力降低NR设备的特征和能力参数，并提升能力降低NR设备的节电性能和电池寿命及使用时间。能力降低NR设备的低复杂度和更低的处理能力主要体现在以下几个方面：降低的设备收发天线个数、减小的传输带宽、只支持半双工FDD、数据处理时间更长和更低的数据处理能力等。能力降低UE需要将能力上报网络，使得网络可以根据能力降低UE的能力，对这些UE应用适当的传输方式，或对这些UE应用更有效的节电机制。
应该注意，上面对技术背景的介绍只是为了方便对本申请的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本申请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
发明人发现，LTE系统将LTE终端的能力定义为不同的能力等级(UE category)，表明了终端支持的最大传输块大小、空分复用能力、调制编码能力等。所有LTE终端必须对应一种或几种能力等级，LTE终端将能力上报给网络时需指示自己的能力等级。LTE终端能力等级主要是限制了不同能力的能力终端最小应支持的最大传输块大小，但是，最大传输块大小跟很多其他的能力参数有关，例如带宽、调制编码方式等，因此，最大传输块大小不能直接体现UE能力。
在LTE R8版本中定义了5类终端，R10版本定义了8类终端，随着版本演进不断有新定义的能力等级，目前R16版本支持多达26类终端，大大增加了LTE终端入网测试的工作量，并且加剧了LTE终端市场的碎片化，原因是产品种类繁多，增大了市场解决方案落地的难度。如果将LTE的能力等级机制应用于能力降低UE，将使NR产品定制过于分散化，并且不能体现该类UE所降低的能力。NR系统取消了能力等级的定义，UE是将具体的各项能力参数上报给网络。但是如果继续使用现有的NR能力上报机制，则不利于网络对能力降低UE的识别。
为了解决上述问题的至少一种或其它类似问题，本申请实施例提供了一种终端能力的传输方法、装置和系统。

下面结合附图对本申请的各种实施方式进行说明。这些实施方式只是示例性的，不是对本申请的限制。
第一方面的实施例
本申请实施例提供一种终端设备能力的传输方法，从终端设备的一侧进行说明。
图1是本申请实施例的终端设备能力的传输方法的一个示例的示意图，如图1所示，该方法包括：
101：终端设备向网络设备发送RRC消息，所述RRC消息包含用于指示第二终端设备类型的信息；其中，所述第二终端设备类型对应一组终端设备能力，其中，在预设频率范围或预设频段内至少有一种第二终端设备类型，所述第二终端设备类型用于指示所述终端设备所支持的能力。
根据本申请实施例的方法，通过RRC消息中包含的用于指示第二终端设备类型的信息指示第二终端设备类型的终端设备所支持的能力，以及第二终端设备类型(即指示该终端设备所属的终端设备类型为第二终端设备类型)，便于网络设备获取终端设备能力，并识别终端设备类型，尤其是识别第二终端设备类型，避免了NR终端产品过于分散化，减小终端设备入网测试的复杂度，并且降低了市场解决方案落地的难度。
在一些实施例中，预设频率范围包括FR1频段范围或FR2频段范围。例如，在FR1频段范围内至少有一种第二终端设备类型，在FR2频段范围内至少有一种第二终端设备类型。
在本申请实施例中，FR1频段范围是6GHz以下，例如450MHz～6000MHz，属于低频段范围；FR2频段范围是6GHz以上，例如24250MHz～52600MHz，属于高频段范围。网络设备通过终端设备的上述用于指示第二终端设备类型的信息可以获得部分终端设备能力。并且，由于工作频段范围是网络设备已知的，因此终端设备只需要指示自己是第二类终端设备，网络设备即可获知终端设备对应的类型。
下面的表1示出了在FR1频段范围内和FR2频段范围内分别有一种第二终端设备类型的情况。
表1：
Device type Bandwidth Tx/Rx antenna
Type 1 for FR1 20MHz 1 Tx/1 Rx，or 2Rx
Type 2 for FR2 50MHz or 100MHz 1 Tx/2 Rx
在一些实施例中，预设频率范围包括FR1频段范围中的中频段(例如低于2GHz的FR1频段)、FR1频段范围中的低频段(例如高于2GHz的FR1频段)、或FR2频段范围。例如，在FR1频段范围中的中频段内至少有一种第二终端设备类型，在FR1频段范围中的低频段内至少有一种第二终端设备类型，在FR2频段范围内至少有一种第二终端设备类型。
下面的表2示出了FR1频段范围中的中频段内、在FR1频段范围中的低频段内、以及在FR2频段范围内分别有一种第二终端设备类型的情况。
表2：
Device type Frequency Range Tx/Rx antenna Bandwidth
Type 1 for FR 1 {n7,n38,n41,n77,n78,n79}(中频) 1Tx/2Rx 20MHz
Type 2 for FR 1 All other bands(低频) 1Tx/1 Rx 20MHz
Type 3 for FR 2 All bands 1Tx/2 Rx 50MHz,or 100MHz
在本申请实施例中，当在预设频率范围内只有一种第二终端设备类型时，所有第二类终端设备都属于这种类型，并且，该第二终端设备类型包括或对应一组终端设备能力。这组终端设备能力代表所有属于第二终端设备类型的终端设备所支持的能力。由此，网络设备通过上述用于指示第二终端设备类型的信息获知该终端设备属于第二终端设备类型，并且，网络设备还可以获知其对应的一组终端设备能力。
在本申请实施例中，当在预设频率范围内有两种或两种以上第二终端设备类型时，每种第二终端设备类型包括或对应一组终端设备能力，分别代表属于这种第二终端设备类型的终端设备所支持的能力。
在一些实施例中，当在预设频率范围内或预设频段内有两种或两种以上第二终端设备类型时，该预设频率范围或预设频段内的第二终端设备类型可以根据以下方式之 一进行分类：
方式一：工业物联网类、视频传感器类和可穿戴设备类；也即，在预设频率范围或预设频段内，第二终端设备类型分为三类，分别为工业物联网类、视频传感器类和可穿戴设备类，每一类对应一组终端设备能力；
方式二：终端设备能力等级；例如高端能力等级和低端能力等级，由此，在预设频率范围或预设频段内，第二终端设备类型分为两类，分别为高端类和低端类，每一类对应一组终端设备能力；
方式三：半频分双工(Half-FDD)类和时分双工(TDD)类；也即，在预设频率范围或预设频段内，第二终端设备类型分为两类，分别为半频分双工类和时分双工类，每一类对应一组终端设备能力。
上述方式一是根据应用场景进行的分类，本申请不限于此，根据应用场景，第二终端设备类型还可以分为多于三类或者少于三类。由此，网络设备能够识别终端设备的应用场景，还能够获得部分终端设备能力，并且，通过接入控制基站可以保证不同应用场景的设备在相应的场景中使用。
下面的表3示出了按照应用场景(方式一)对第二终端设备类型进行分类后，不同种类的第二终端设备类型所对应的终端设备能力。
表3：
Device type Use cases Bandwidth Tx/Rx antenna
Type 1 RedCap Industrial sensors 20MHz 1 Tx/1 Rx
Type 2 RedCap Video surveillance 20MHz 1 Tx/1 Rx
Type 3 RedCap Wearables 20MHz 1 Tx/1 Rx
在表3的示例中，以终端设备能力包括的参数为带宽(bandwidth)和收发天线(Tx/Rx antenna)为例，但本申请不限于此，关于终端设备能力所包括的参数将在后面进行说明。
上述方式二是根据终端设备的能力等级进行的分类，例如在FR1频段范围内分为高端能力等级和低端能力等级，高端能力等级支持更高的传输速率，例如支持150Mbps峰值速率。由此，网络设备能够识别终端设备属于高端设备还是低端设备，此外，网络设备还能够获得部分终端设备能力。
下面的表4示出了按照终端设备的能力等级(方式二)对第二终端设备类型进行分类后，不同种类的第二终端设备类型所对应的终端设备能力。
表4：
Figure PCTCN2020122608-appb-000001
在表4的示例中，同样以终端设备能力包括的参数为带宽(bandwidth)和收发天线(Tx/Rx antenna)为例，但本申请不限于此，关于终端设备能力所包括的参数将在后面进行说明。
上述方式三是根据双工方式进行的分类，例如分为半频分双工(Half-FDD)类和时分双工(TDD)类。FR1上分为Half-FDD类和TDD类，FR2上只有一种类型，例如为Hafl-FDD类。由此，由于系统的双工方式是网络设备已知的，因此，终端设备不需要指示不同的类型，只需要指示自己为第二类终端设备(也即至少属于某一种第二终端设备类型的终端设备)，网络设备即可获知终端设备对应的类型。
下面的表5示出了按照双工方式(方式三)对第二终端设备类型进行分类后，不同种类的第二终端设备类型所对应的终端设备能力。
表5：
Device type Duplex mode Tx/Rx antenna Bandwidth
Type 1 for FR 1 Half-FDD 1Tx/1 Rx or 2Rx 20MHz
Type 2 for FR 1 TDD 1Tx/1 Rx or 2Rx 20MHz
Type 3 for FR 2 Half-FDD 1Tx/2 Rx 50MHz,or 100MHz
在本申请实施例中，第二类终端设备又称为非常规UE或能力降低UE，一般情况下，非常规UE的能力低于常规UE的能力，常规UE属于第一类终端设备。UE能力包括带宽(bandwidth)、收发天线(Rx/Tx antenna)、双工方式和处理时间等。处理时间例如为N1或N2，N1为PDSCH最后一个符号与反馈ACK的PUCCH的第一个符号之间的最小时间间隔，N2为DCI最后一个符号与被调度的PUSCH第一个符号之间的最小时间间隔。
一般情况下，常规UE至少支持100MHz带宽，4Tx/4Rx天线，可以支持FDD/TDD；非常规UE可能在FR1最大只能支持20MHz带宽，在FR2最大支持50MHz或100MHz 带宽，1Tx/1Rx或2Rx天线，不支持FDD，只支持TDD/Half-FDD。此外，常规UE在子载波间隔(SCS)为15，30，60，和120kHz时的PDSCH最小处理时间(N1)分别是8，10，17和20个符号，PUSCH最小处理时间(N2)分别是10，12，23和36个符号；非常规UE的处理能力低于常规UE，在子载波间隔(SCS)为15，30，60，和120kHz时的最小PDSCH处理时间分别是16，20，34，和40个符号，最小PUSCH处理时间分别是20，24，46，和72符号。
在本申请实施例中，每种第二终端设备类型对应的一组终端设备能力至少包括带宽或收发天线个数。
在一些实施例中，第二终端设备类型对应的一组终端设备能力还包括处理时间以及双工方式。在这些实施例中，第二终端设备类型对应的终端设备能力由低于常规UE的能力构成，属于第二终端设备类型的终端设备(也即第二类终端设备)也称为非常规UE，也即，上述四项参数(带宽、收发天线个数、处理时间和双工方式)可以用于区分常规UE和非常规UE。例如，非常规UE支持的双工方式为Half-FDD，不支持FDD，而常规UE(也即第一类终端设备)支持FDD，则可通过该参数区分常规UE和非常规UE。
在上述实施例中，除了以上四项参数，非常规UE可能在其他能力方面与常规UE有相同水平。第二终端设备类型(非常规UE类型)由上述四项参数定义，可以使网络设备获知终端设备具有的那些低于常规UE的能力。
在上述实施例中，带宽、收发天线个数、处理时间(N1/N2)这三项能力还与非常规UE进行初始随机接入相关。非常规UE这三项能力低于常规UE，会影响初始随机接入的msg2/msg3及后续PDCCH/PUSCH/PDSCH/PUCCH的传输。因为非常规UE支持的带宽限制，网络设备必须保证msg2/msg3及PDCCH/PUSCH/PDSCH/PUCCH的资源带宽在非常规UE支持的带宽以内；1Rx天线使非常规UE接收敏感度降低，网络设备需要对msg2/msg3及PUSCH/PDSCH/PDSCH做重复传输(repitition)；非常规UE的PUSCH/PDSCH处理时间较长，网络设备需保证对PUSCH的调度和PDSCH的ACK/NACK的调度满足非常规UE支持的最小处理时间。非常规UE不支持FDD会影响随机接入后续的上/下行传输，因为网络设备要保证对非常规UE不同时调度上/下行传输。非常规UE类型由这四种能力定义，可以使网络设备获得非常规UE的能力，对非常规UE应用适合的传输方式，保证与非 常规UE的正常通信。
在一些实施例中，第二终端设备类型对应的一组终端设备能力还包括多输入多输出(MIMO)层数、调制方式、传输块大小以及混合自动重传请求进程(HARQ process)个数。在这些实施例中，第二终端设备类型对应的能力由区分非常规UE的能力等级或应用场景构成，也即，上述六项参数(带宽、收发天线个数、MIMO层数、调制方式、传输块大小和HARQ进程)可以用于区分非常规UE的能力等级或应用场景。
在上述实施例中，带宽、收发天线个数，MIMO层数、调制方式、传输块大小或HARQ进程个数都是与UE的峰值速率相关的能力，对于高、低端类型的UE有不同的能力范围。由这些参数定义非常规UE类型，可以使网络设备获得不同等级的非常规UE能力，还可以基于非常规UE的能力等级或应用场景，对非常规UE做接入控制。
在本申请实施例中，第二终端设备类型对应的一组终端设备能力的参数值可以代表属于上述第二终端设备类型的终端设备支持的最大能力；或代表属于上述第二终端设备类型的终端设备支持的最大能力的下限；或者，可以代表属于上述第二终端设备类型的终端设备支持的最大能力的上限。
在上述实施例中，第二终端设备类型对应的能力参数代表属于上述第二终端设备类型的终端设备支持的最大能力，所有属于该非常规UE类型的终端设备支持的最大能力相同。
例如，有两种非常规UE类型(Type 1和Type 2)，分别对应FR1和FR2，如下面的表6所示，其中，每种类型对应两项UE能力，分别为带宽和收发天线个数。则所有属于Type 1的终端设备都支持最大带宽20MHz，最少天线数1 Tx/1 Rx，所有属于Type 2的终端设备都支持50MHz，最小天线数1Tx/2 Rx。
表6：
Device type Bandwidth Tx/Rx antenna
Type 1 for FR1 20MHz 1 Tx/1 Rx
Type 2 for FR2 50MHz 1 Tx/2 Rx
再例如，有三种非常规UE类型(Type1，Type2，Type3)，Type 1和Type 2对应FR1，Type3对应FR2，如下面的表7所示，其中，每种类型对应两项UE能力，分别是带宽和收发天线个数。则所有属于Type 1的UE都支持最大带宽20MHz，最小 天线数1Tx/2Rx；所有属于Type 2的UE都支持最大带宽20MHz，最小天线数1Tx/1Rx；所有属于Type 3的UE都支持最大带宽50MHz，最小天线数1Tx/2Rx。
表7：
Device type Frequency Range Tx/Rx antenna Bandwidth
Type 1 for FR 1 {n7,n38,n41,n77,n78,n79}(中频) 1Tx/2Rx 20MHz

Type 3 for FR 2 All bands 1Tx/2Rx 50MHz
在上述实施例中，第二终端设备类型对应的能力参数代表属于上述第二终端设备类型的终端设备支持的最大能力的下限，所有属于该非常规UE类型的终端设备必须支持这组能力。

在上述实施例中，第二终端设备类型对应的能力参数代表属于上述第二终端设备类型的终端设备支持的最大能力的上限，属于该非常规UE类型的终端设备支持的最大能力不超过该参数。
例如，有两种非常规UE类型(Type 1和Type 2)分别对应FR1和FR2，如下面的表9所示，其中，每种类型对应两种UE能力，分别是调制方式和MIMO层数。则所有属于Type 1的UE支持的最高调制方式不超过64QAM(下行)或16QAM(上行)，最大MIMO层数不超过2；所有属于Type 2的UE支持的最高调制方式不超过16QAM，最大MIMO层数不超过2。

Type 2 for FR2 16QAM for DL；16QAM for UL 1 for DL/UL

在上述实施例中，在第二终端设备类型对应的能力参数代表属于该类型的终端设备支持的最大能力的情况下，UE在发送UECapabilityInformation(UE能力指示消息)时，消息里可以不包含这些参数，因为通过第二设备类型和每种类型对应的能力参数，网络设备已经可以获得UE的这些能力。
