Abstract

Description

无线网络接入方法、装置、通信设备及存储介质 技术领域
本申请涉及无线通信技术领域但不限于无线通信技术领域，尤其涉及一种无线网络接入方法、装置、通信设备及存储介质。
背景技术
在新空口(NR，New Radio)系统中引入辅助上行(SUL，Supplementary Uplink)特性，以提升新空口系统的上行覆盖能力。即在同一个小区中配置一个下行载波和两个上行载波。这里，两个上行载波分别为辅助上行SUL载波和非辅助上行non-SUL载波。在同一时刻，终端只能选择一个载波进行物理上行共享信道(PUSCH，Physical Uplink Shared Channel)的上行传输。在新空口NR系统中，在辅助上行特性引入后，对于新空口NR系统中的终端而言，为减少所有终端都在辅助上行SUL载波上发起随机接入，只允许位于小区边缘的终端在辅助上行SUL载波上发起随机接入过程。
在R17中，针对轻量版新空口(NR-Light，New Radio-Light)特性，引入了一种低复杂度的新类型的终端，旨在应对R15/R16的增强移动带宽(eMBB，Enhanced Mobile Broadband)、低延时高可靠通信(URLLC，Ultra Reliable&Low Latency Communication)、海量物联网通信(mMTC，Massive Machine Type Communication)之外的场景。该种低复杂度的新类型终端所要求的速率、时延、可靠性都未被上述场景覆盖。例如，数据传输时的速率要求比增强移动带宽eMBB的要求要低、速率要求比海量物联网通信mMTC要求要高，且传输时延和传输可靠性要求，又比低延时高可靠通信URLLC更加宽松。
在R17中，针对轻量版新空口NR-light特性，低复杂度的新类型的终 端引入之后，终端的天线减少，对于上行覆盖增强有了更高的要求。因此，该种低复杂度的新类型的终端需要尽量工作在辅助上行SUL载波上。但是，只允许位于小区边缘的终端在辅助上行SUL载波上发起随机接入过程的接入方式并不能很好地满足该种低复杂度的新类型终端的接入需求，不能增强网络的上行覆盖能力。

其中，终端11可以是指向用户提供语音和/或数据连通性的设备。终端11可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，终端11可以是物联网终端，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程终端(remote terminal)、接入终端(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户终端(user equipment，UE)。或者，终端11也可以是无人飞行器的设备。或者，终端11也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线通信设备。或者，终端11也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站12可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口(new radio，NR)系统或5G NR系统。或者，该无线通信系统也可以是5G系统的再下一代系统。其中，5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。或者，MTC系统。
其中，基站12可以是4G系统中采用的演进型基站(eNB)。或者，基站12也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站12采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站12的具体实现方式不加以限定。
基站12和终端11之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中，终端11之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(vehicle to everything，V2X)中的V2V(vehicle to vehicle，车对车)通信、V2I(vehicle to Infrastructure，车对路边设备)通信和V2P(vehicle to pedestrian，车对人)通信等场景。
在一些实施例中，上述无线通信系统还可以包含网络管理设备13。
若干个基站12分别与网络管理设备13相连。其中，网络管理设备13可以是无线通信系统中的核心网设备，比如，该网络管理设备13可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户网络侧设备(Home Subscriber Server，HSS)等。对于网络管理设备13的实现形态，本公开实施例不做限定。
为了更好地理解本公开任一个实施例所描述的技术方案，首先，通过一个实施例对辅助上行SUL场景进行说明。
在一个实施例中，请参见图2，在3.5G上行无覆盖的地方(图2中示出的远点)增开低频段(对应SUL载波频段)传输上行数据。通过在高频段上传输5G新空口NR的下行数据，在低频段上传输5G新空口NR上行数据，从而提升5G的上行覆盖。其中，辅助上行SUL载波可能和LTE上行载波在同一个频段。相较于NR载波，辅助上行SUL载波使用的是低频段。
对于处于空闲态的终端，选择哪个载波进行初始随机接入取决于参考信号接收功率(RSRP，Reference Signal Receiving Power)的门限。终端在检测到参考信号接收功率RSRP低于门限的时候，才从辅助上行载波发起初始随机接入(RA，Random Access)过程。则整个随机接入信道(RACH，Random Access Channel)流程将在该载波完成。此时的随机接入过程为竞争的随机接入过程。当终端有上行数据到达，而处于上行失步的时候，终端选择上行载波发起随机接入的过程同空闲态UE。而对于处于连接态的终端而言，网络可以通知处于连接态的终端在哪个上行载波发起随机接入。 例如，网络在专用命令中通知终端在哪个上行载波发起随机接入。此时随机接入过程为非竞争的随机接入过程。
在R17中，针对增强移动带宽(eMBB，Enhanced Mobile Broadband)、低延时高可靠通信(URLLC，Ultra Reliable&Low Latency Communication)、海量物联网通信(mMTC，Massive Machine Type Communication)之外的场景引入了新类型的终端。三种典型终端为工厂传感器、视频监控设备和可穿戴设备。该新类型的终端具有如下特性：
1、天线减少；例如，从R15的4个减少为2个或者1个。
2、带宽降低；例如，频段1(FR1，Frequency Range 1)的典型值为5MHz/10MHz。频段2(FR2，Frequency Range 2)的典型值为40MHz。
3、终端处理能力降低；例如，可能会支持更小的传输块(TB，Transport Block)和下行控制信息(DCI，Downlink Control Information)。
这里，新类型的终端上行覆盖能力较弱，需要尽量工作在辅助上行SUL载波上。
如图3所示，本公开一个实施例提供了一种无线网络接入方法，应用于终端中，该方法包括：
步骤31，根据终端的类型，确定是否允许终端在辅助上行SUL载波上接入无线网络。
在一个实施例中，终端可以包括如下特征：1、天线数量在设置范围内。2、通信带宽较低，即工作在较低频段。例如，5MHz/10MHz、40MHz等。3、终端的数据处理能力较弱，只能处理小的传输块TB和下行控制信息DCI。
这里，终端可以是工厂传感器、视频监控设备和可穿戴设备。这里，可穿戴设备可以是智能手表、智能手环、智能头盔和智能眼镜等。
在一个实施例中，终端的类型可以是根据终端进行数据传输时所要求的传输速率、传输时延、传输可靠性等性能参数的不同进行区分。例如， 终端在数据传输时所要求的传输速率在第一速率范围内、传输时延在第一时延范围内且传输可靠性符合第一条件，则此类终端为第一类型的终端。在一个实施例中，数据传输时的速率要求比增强移动带宽eMBB的要求要低、速率要求比海量物联网通信mMTC的要求要高，且传输时延和传输可靠性要求，又比低延时高可靠通信URLLC要宽松的终端为第一类型的终端。
在一个实施例中，可以根据如下之一的终端特征确定终端为第一类型的终端：终端的天线数目、终端在数据传输的速率、终端采用的调制编码方式、终端支持的通信带宽。
在一个实施例中，终端根据设置的天线数目确定终端的类型。例如，当终端具有预定个数(例如，仅具有一个)天线时，确定终端为第一类型的终端。
在另一个实施例中，终端根据终端能力确定终端的类型。例如，当终端支持的带宽小于设置阈值20MHz时，确定终端为第一类型的终端。
在一个实施例中，设置阈值可以通过专用信令或者广播信令的方式通知终端。这里，专用信令可以是无线资源控制(RRC，Radio Resource Control)信令。
在另一个实施例中，设置阈值可以通过通信协议事先约定。当终端在进行通信时，根据通信所采用的通信协议类型确定设置阈值。
在一个实施例中，如果终端工作在覆盖增强模式，确定终端为第一类型的终端。这里，确定终端是否工作在覆盖增强模式的方式可以是：判断终端在选择小区的时候是否使用了小于设置阈值的RSRP。例如，终端使用了小于设置阈值的RSRP选择了小区，则驻留在小区后终端工作在覆盖增强模式下。
在一个实施例中，当终端的类型满足预先设置的条件时，允许终端在 辅助上行SUL载波上接入无线网络。
在另一个实施例中，当终端的类型不满足预先设置的条件时，不允许终端在辅助上行SUL载波上接入无线网络。这里，当终端的类型不满足预先设置的条件时，可以在非辅助上行non-SUL载波上接入无线网络。
在本公开实施例中，根据所述终端的类型，确定是否允许所述终端在SUL载波上接入无线网络。这样，当所述终端的类型为允许在SUL载波上接入无线网络的终端类型时，就可以在SUL载波上接入无线网络。相较于只有在小区边缘的终端才能通过SUL载波接入无线网络的情况，在本公开实施例中会根据终端的类型，允许在SUL载波上接入无线网络的终端在小区范围内都可以接入无线网络。使得有必要在SUL载波上进行无线接入的终端直接在SUL载波上进行无线接入，或者在相比其他终端有更加宽松的条件下在SUL载波上进行无线接入。从而提升了有必要在SUL载波上接入的终端的上行覆盖能力。
如图4所示，本公开另一个实施例提供了一种无线网络接入方法，在步骤32中，所述根据所述终端的类型，确定是否允许所述终端在SUL载波上接入无线网络，包括：
步骤41，若终端为第一类型的终端，确定允许终端在SUL载波上接入无线网络。
在一个实施例中，第一类型的终端可以是在数据传输时所要求的传输速率为第一速率、传输时延为第一时延且传输可靠性符合第一条件的终端。
这里，若终端为第一类型的终端，终端就可以在小区中的任何位置直接在SUL载波上接入无线网络，而不需要其他接入条件(例如，参考信号接收功率RSRP小于设置阈值)的限制，提高了第一类型的终端的上行覆盖能力，使第一类型的终端能够快速接入无线网络。
或者，
若终端为第一类型的终端，在满足第一类型的终端的SUL接入条件时，确定允许终端在SUL载波上接入无线网络。
且进一步地，在第一类型的终端在不满足SUL接入条件时，可在非SUL载波(即SUL载波以外的载波)上进行接入。
在一个实施例中，第一类型的终端的SUL接入条件可以是：终端检测到的参考信号接收功率RSRP小于第一功率阈值。即，在第一类型的终端检测到参考信号接收功率大于或等于第一功率阈值时，说明第一类型的终端的当前信道条件较好，无需在特意在SUL上进行无线接入，就能够获得比较好的覆盖，此时，可以将SUL载波空闲出来供其他有需求的终端在SUL上进行无线接入。
在一个实施例中，第一功率阈值的大小可以根据小区中第一类型的终端的数量设置。例如，当第一类型的终端的数量大于A时，可以设置大于B的第一功率阈值；当第一类型的终端的数量小于A时，可以设置小于B的第一功率阈值。这里，在无线通信时信号正常情况下，参考信号接收功率RSRP通常是大于设置值的。只有当信号较差时，才会出现参考信号接收功率RSRP下降的情况。这里，将第一功率阈值设置得越大，终端的参考信号接收功率RSRP就越容易满足小于第一功率阈值的条件，第一类型的终端也就越容易通过SUL接入无线网络。
如图5所示，本公开另一个实施例提供了一种无线网络接入方法，在步骤32中，所述根据所述终端的类型，确定是否允许所述终端在SUL载波上接入无线网络，包括：
步骤51，若终端为第二类型的终端，在满足第二类型的终端的SUL接入条件时，确定允许终端在SUL载波上接入无线网络。
其中，第一类型的终端的SUL接入条件比第二类型的终端的SUL接入条件宽松。
这里，第一类型的终端不同于第二类型的终端。
在一个实施例中，第一类型的终端可以是在数据传输时所要求的传输速率为第一速率、传输时延为第一时延且传输可靠性符合第一条件的终端。第二类型的终端可以是在数据传输时所要求的传输速率为第二速率、传输时延为第二时延且传输可靠性符合第二条件的终端。这里，第一速率低于第二速率，第一时延低于第二时延，第一条件要求的可靠性比第二条件要求的可靠性低。
在一个实施例中，第二类型的终端的SUL载波接入条件可以是：终端检测到的参考信号接收功率RSRP小于第二功率阈值。
在一个实施例中，第二功率阈值的大小可以根据第二类型的终端的数量设置。例如，当第二类型的终端的数量大于C时，可以设置小于D的第二功率阈值；当第二类型的终端的数量小于C时，可以设置大于D的第二功率阈值。这里，在无线通信时信号正常情况下，参考信号接收功率RSRP通常是大于设置值的。只有当信号较差时，才会出现参考信号接收功率RSRP下降的情况。这里，将第二功率阈值设置得越小，第二类型的终端的参考信号接收功率RSRP就越难满足小于第二功率阈值的条件，数量较大的第二类型的终端也就越难通过SUL接入无线网络。
在一个实施例中，第一类型的终端的SUL接入条件可以是：终端检测到的参考信号接收功率RSRP小于第一功率阈值。第二类型的终端的SUL载波接入条件可以是：终端检测到的参考信号接收功率RSRP小于第二功率阈值。
在一个实施例中，第一类型的终端的SUL接入条件比第二类型的终端的SUL接入条件宽松可以是：第一功率阈值大于第二功率阈值。在无线通信时信号正常情况下，参考信号接收功率RSRP通常是大于设置值的。只有当信号较差时，才会出现参考信号接收功率RSRP的下降。这里，功率 阈值越大，终端越容易满足参考信号接收功率RSRP小于功率阈值的条件。由于第一功率阈值大于第二功率阈值，则第一类型的终端比第二类型的终端更加容易通过SUL接入无线网络，以确保有必要进行上行覆盖增强的第一类型的终端，能够在不被第二类型的终端挤占的情况下，通过SUL接入到无线网络。
在本实施例中，一方面，第一类型的终端和第二类型的终端在参考信号接收功率RSRP符合条件的情况下，都可以通过SUL载波接入无线网络。这样，在无线信号较弱时，或者终端接收和/或发送无线信号的能力较弱时，都可以通过SUL载波接入无线网络，提升了无线网络的覆盖能力。另一方面，在给第一类型的终端和第二类型的终端设置SUL接入条件时，第一类型的终端的SUL接入条件比第二类型的终端的SUL接入条件更加宽松，这样，第一类型的终端比第二类型的终端更加容易通过SUL载波接入无线网络，可以优先满足第一类型的终端通过SUL载波接入无线网络，优先工作在SUL载波上。
如图6所示，本公开另一个实施例提供了一种无线网络接入方法，所述方法还包括：
步骤61，若终端为第一类型的终端，在不满足第一类型的终端的SUL接入条件时，确定终端在非SUL载波上接入无线网络。
其中，SUL载波和非SUL载波属于相同的或不同的定时提前组TAG。
在一个实施例中，不满足第一类型的终端的SUL接入条件可以是：终端检测到的参考信号接收功率RSRP大于第一功率阈值。
在一个实施例中，若终端为第二类型的终端，在不满足第二类型的终端的SUL接入条件时，确定终端在非SUL载波上接入无线网络。
其中，SUL载波和非SUL载波属于相同的定时提前量组(TAG，Timing Advance Group)；或者，SUL载波和非SUL载波属于不同的定时提前量组。
在一个实施例中，在同一个小区中配置一个下行载波和两个上行载波。这里，两个上行载波分别为SUL载波和非SUL载波。同一个时刻，终端只能选择一个载波进行上行传输。既终端只能选择SUL载波进行上行传输，或者选择非SUL载波进行上行传输。这里，SUL载波使用的是低频段。
这里，终端在不能通过SUL载波接入无线网络时，还能够通过非SUL载波接入无线网络，两种接入方式相互互补，确保了终端的通信顺畅。
在一个小区内同时为终端配置了SUL载波和非SUL载波，SUL载波和非SUL载波的载波频率不同。在一些情况下，若SUL载波和非SUL载波的频率相差很大，通过相同传输环境的衰减值或传播速率不同时，可以根据SUL载波和非SUL载波，配置适用于当前载波频率的不同定时提前量组。在另一些情况下，若SUL载波和非SUL载波的频率相差不大，则对于终端而言，其定时提前量更多的取决于终端与基站之间的距离，此时可以将同一个终端的SUL载波和非SUL载波设置为具有相同的定时提前量，从而配置一个终端的SUL载波和非SUL载波属于同一个定时提前量组。
在一个实施例中，不满足第二类型的终端的SUL接入条件可以是：终端检测到的参考信号接收功率RSRP大于第二功率阈值。
在一个实施例中，第一类型的终端的SUL接入条件包括：第一类型的终端的参考信号接收功率小于第一功率阈值；第二类型的终端的SUL接入条件包括：第二类型的终端的参考信号接收功率小于第二功率阈值；其中，第一功率阈值大于第二功率阈值。
在一个实施例中，第一类型的终端的天线数量在设置数量范围内；
和/或，
第一类型的终端在传输数据时的上行速率在第一速率范围内；
和/或，
第一类型的终端在传输数据时的下行速率在第二速率范围内；
和/或，

和/或，
所述第一类型的终端为：支持的带宽在设置带宽范围内的终端；
和/或，
所述第一类型的终端为：工作在覆盖增强模式的终端。
在一个实施例中，设置数量N范围可以是0<N<3；其中，N为终端中设置的天线数量，N为整数。
在一个实施例中，第一速率范围不同于第二速率范围。
在一个实施例中，第一类型的终端在编码待传输的数据时采用的预设编码方式不同于第二类型的终端在编码待传输的数据时采用的编码方式。
这里，第一类型的终端在编码待传输的数据时采用的预设编码方式可以是更低阶的调制编码方式。例如，第一类型的终端在编码待传输的数据时采用32阶正交幅度调制(32QAM，32 Quadrature Amplitude Modulation)方式，第二类型的终端在编码待传输的数据时采用64阶正交幅度调制(64QAM，64Quadrature Amplitude Modulation)方式。
在一个实施例中，支持的带宽在设置范围内可以是在5MHz至40MHz的范围内。例如，支持的带宽为5MHz、10MHz、40MHz等。
在一个实施例中，确定终端是否工作在覆盖增强模式的方式可以是：判断终端在选择小区的时候是否使用了小于设置阈值的RSRP。例如，终端使用了小于设置阈值的RSRP选择了小区，则驻留在小区后终端工作在覆盖增强模式下。
在一个实施例中，第一类型的终端和第二类型的终端在SUL载波上接入无线网络的接入参数的种类或接入参数的参数值不同。
在一个实施例中，因为第一类型的终端需要在SUL上进行重复传输， 第一类型的终端和第二类型的终端在SUL载波上接入无线网络的接入参数的种类不同。一种可能的实施方式中，第一类型的终端的接入参数包括传输前导码的重复传输次数，而第二类型的终端的接入参数不包括传输前导码的重复传输次数。
在一个实施例中，所述接入参数的参数值不同可以是参数值的大小不一样。在一个实施例中，第一类型的终端在SUL载波上接入无线网络的接入参数的参数值大于第二类型的终端在SUL载波上接入无线网络的接入参数的参数值。
在一个实施例中，接入参数包括如下一种或多种：最大发射功率P CMAX,f,c、随机前导码的发射功率调整步长PREAMBLE_POWER_RAMPING_STEP、请求获取系统消息SI资源的配置参数。
在一个实施例中，第一类型的终端的P CMAX,f,c大于第二类型的终端的P CMAX,f,c；
或者，
第一类型的终端的PREAMBLE_POWER_RAMPING_STEP大于第二类型的终端的PREAMBLE_POWER_RAMPING_STEP；
或者，
在发起基于需求的系统消息ondemand SI资源请求时，第一类型的终端使用第一配置参数获取SI资源；第二类型的终端使用第二配置参数获取SI资源；其中，第一配置参数不同于第二配置参数。
在一个实施例中，在数据传输时，会用到64个前导码。第一配置参数包括第1个至32个前导码，第二配置参数包括第33个至第64个前导码。
在一个实施例中，当第一类型的终端在SUL载波上接入无线网络时，配置第一系统消息SI请求参数。当第二类型的终端在SUL载波上接入无线 网络时，配置第二系统消息SI请求参数。其中，第一系统消息SI请求参数不同于第二系统消息SI请求参数。
