为了能够更加详尽地了解本申请实施例的特点和技术内容,下面结合附图对本申请实施例的实现进行详细阐述,所附附图仅供参考说明之用,并非用来限定本申请实施例。
在对本申请实施例提供的上行接入方法进行详细说明之前,先对相关技术中上行接入方法的相关信息进行简要说明。
随着人们对速率、延迟、高速移动性、能效的追求以及未来生活中业务的多样性和复杂性,3GPP国际标准组织开始研发5G。5G的主要应用场景为:增强移动超宽带(Enhance Mobile Broadband,eMBB)、低时延高可靠通信(Ultra Reliable Low Latency Communications,URLLC)、和大规模机器类通信(Massive Machine Type Communication,mMTC)。
eMBB仍然以用户获得多媒体内容、服务和数据为目标,其需求增长十分迅速。另一方面,由于eMBB可能部署在不同的场景中,便如室内,市区,农村等,其能力和需求的差别也比较大,所以不能一概而论,必须结合具体的部署场景详细分析。URLLC的典型应用包括:工业自动化,电力自动化,远程医疗操作(手术),交通安全保障等。mMTC的典型特点包括:高连接密度,小数据量,时延不敏感业务,模块的低成本和长使用寿命等。
新无线(New Radio,NR)系统也可以独立部署,为了降低空口信令、快速恢复无线连接和快速恢复数据业务,定义了新的无线资源控制(Radio Resource Control,RRC)状态,即RRC-Inactive(去激活)状态。其中,RRC-Idle(空闲)状态下,移动性为基于终端设备的小区重选,寻呼过程由核心网(Core Network,CN)发起,寻呼区域由CN配置。网络设备侧不存在终端设备上下文,也不存在RRC连接。RRC-Inactive状态下,移动性为基于终端设备的小区重选,存在CN-NR之间的连接,终端设备上下文存在于某个网络设备上,寻呼过程由无线接入网(Radio Access Network,RAN)触发,基于RAN的寻呼区域由RAN管理,网络设备能够知道终端设备的位置是基于RAN的寻呼区域级别的。RRC-Connected(连接)状态下,存在RRC连接,网络设备和终端设备之间存在终端设备上下文,网络设备知道终端设备的位置是具体小区级别的;移动性是网络设备控制的移 动性,网络设备与终端设备之间可以传输单播数据。
在R17中引入了NR-light的设备,NR-light的设备可以由三个场景,包括:
1、工业无线传感器(Industrial Wireless Sensors,IWS),与URLLC设备相比,IWS具有相对低要求的时延和可靠性,同时,设备的成本和功耗也较URLLC设备和eMBB设备低。
2、视频监控(Video surveillance)设备,主要用于智慧城市、工业工厂等视讯监控以及智能城市中数据收集和处理,以便于更有效的进行城市资源的监测和控制,给城市居民提供更有效的服务。
3、可穿戴设备(Wearables),可穿戴设备至少可以包括智能手表、电子健康设备以及一些医疗监测设备等。可穿戴设备的共性为设备的尺寸小。
上述三个场景的共性需求为:
1、设备成本低;通过降低带宽和接收天线,降低设备的成本和复杂度。
2、设备的尺寸;具有较小的设备尺寸。
3、覆盖率;要求达到与R15或R16相当的覆盖率;若由于降低接收天线、或降低带宽、或降低功率等级、或降低终端设备复杂度导致覆盖损失,则需要对覆盖损失进行补偿。
上述三个场景的非共性需求为:
1、Industrial wireless sensors:可靠性需求为99.99%,端到端时延需求为100ms。Bit速率需求为2Mbps;设备静止不动;电池寿命是几年;对于安全相关的传感器,时延需求为5-10ms。
2、Video Survaillance:Bit速率需求为2-4Mbps,时延需求<500ms,可靠性需求为99%-99.9%,对于某些高端视频速率需求为2-4Mbps,上行业务量比较大。
3、Wearables:速率需求为150Mbps/50Mbps。
下面再对带宽部分(BandWith Part,BWP)进行简要说明:
NR系统中支持的最大信道带宽可以到400MHZ宽带载波(wideband carrier),如果终端设备一直保持工作在宽带载波上,则终端设备的功率消耗非常大。根据终端设备实际的吞吐量来调整终端设备的射频(Radio Frequency,RF)带宽可以优化终端设备的功率消耗,进而引入BWP。
处于连接状态的终端设备,一个时刻最多只能有一个激活的下行BWP和一个激活的上行BWP。网络设备可以给连接状态的终端设备配置至多4个上行BWP以及至多4个下行BWP,对于频分双工(Frequency Division Dual,FDD)系统,上行BWP和下行BWP之间没有显示的对应(association)关系。比如,网络设备可以为一个连接状态的终端设备配置4个上行BWP(index分别是0,1,2,3)和4个下行BWP(0,1,2,3),当前激活的上行BWP index可以是0,当前激活的下行BWP index可以是1;如果通过下行控制信息(Downlink Control Information,DCI)将下行BWP切换到另外一个BWP,比如从当前激活的下行BWP 1切换到下行BWP 2,上行BWP可以保持不变。
处于空闲状态和去激活状态的终端设备,通过小区定义的同步信号块(Cell Defining Synchronization Signal Block,CD-SSB)获取驻留小区的主信息块(Master Information Block,MIB)和系统信息块(System Information Block,SIB1)信息。SIB1中指示了用于终端设备初始接入的初始(initial)BWP的相关配置信息,其中包含了initial上行BWP和initial下行BWP。在上行BWP配置中,网络设备为初始接入的终端设备配置随机接入资源(RACH-ConfigCommon),随机接入资源和SSB之间存在对应关系。网络设备通过配置一个RSRP门限(RSRP-Threshold SSB)控制终端设备随机接入资源的选择,随机接入过程被触发时,终端设备选择一个RSRP测量值满足以上RSRP门限的SSB后,按照随机接入资源和SSB的对应关系选择对应的随机接入资源发送前导码(preamble),即发送Msg1,并在选择的SSB上接收网络设备发送的随机接入响应消息,即接收Msg2。
为了提高NR系统高频带上的上行覆盖,引入了补充上行(Supplementary Uplink,SUL)频率。由于终端设备的上行功率受限,而且NR系统的频谱的频率又较高,导致终端设备的上行覆盖会受限。为了提高终端设备的上行覆盖,利用LTE频谱(相对频率较低)作为上行频谱,可以提高上行覆盖。
并且,两个上行载波和一个下行频谱属于同一个小区,在同一时刻最多只存在一个物理上行共享信道(Physical Uplink Shared Channel,PUSCH)传输。除非网络设备明确指示终端设备使用哪个上行载波,否则终端设备根据测量门限判决终端设备的选择。该门限在系统广播里面广播配置。两个上行载波之间可以通过DCI指示进行动态切换。空闲状态或去激活状态的终端设备通过服务小区的RSRP大小来决定是使用正常上行(Normal Uplink,NUL)载波还是SUL来进行初始接入。
本申请提供一种上行接入方法,本申请实施例的上行接入方法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)、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)通信系统或5G系统等。

本申请实施例提供的应用于终端设备的上行接入方法的一种可选处理流程,如图2所示,包括以下步骤:
步骤S201,终端设备根据第一信息在正常上行载波和至少一个第一补充上行载波中,确定一个用于初始接入或数据传输的目标载波。
在一些实施例中,所述第一信息包括下述中的至少一项:所述NUL载波的选择因子信息和所述第一SUL载波的选择因子信息、所述第一SUL载波对应的RSRP门限值、所述第一SUL载波对应的RSRP阈值范围、所述终端设备的类型与所述正常上行载波的对应关系、所述终端设备的类型与所述第一SUL载波的对应关系、业务类型与所述正常上行载波的对应关系、所述业务类型与所述第一SUL载波的对应关系、和网络设备发送的第一指示信息。
本申请实施例提供的上行接入方法还可以包括:
步骤S200,终端设备接收网络设备发送的第一系统消息,所述第一系统消息用于指示第二SUL载波的信息。
在一些实施例中,所述第一系统消息可以为SIB1;所述第二SUL载波的数量为至少一个。
在一些实施例中,所述第一系统消息也可以携带第一信息;即网络设备通过第一系统消息向终端设备发送第一信息。
步骤S200’,所述终端设备基于所述第二SUL载波的信息确定所述第一SUL载波的信息。
在一些实施例中,所述终端设备确定所述第二SUL载波中,所述终端设备支持的SUL载波为所述第一SUL载波。举例来说,网络设备通过SIB1广播X个第二SUL载波,所述X个第二SUL载波中有Y个第二SUL载波是所述终端设备根据自身的无线能力能够支持的载波;则终端设备确定所述Y个第二SUL载波为第一SUL载波。如果第二SUL载波中有至少一个终端设备能够支持的载波,则终端设备确认该小区为可以接入的小区;如果第二SUL载波中没有终端设备能够支持的载波,则终端设备认为该小区被禁止接入,放弃对该小区的驻留,需要发起小区重选过程。
下面分别基于第一信息包括的不同内容对终端设备确定一个用于初始接入或数据传输的目标载波的实现过程进行说明。
1、针对所述第一信息包括NUL载波的选择因子信息和所述第二SUL载波的选择因子信息的情况,所述终端设备可以先确定第一SUL载波的选择因子信息。
若所述终端设备确定第一SUL载波的数量与第二SUL载波的数量相同,则所述终端设备确定所述第一SUL载波的选择因子信息与所述第二SUL载波的选择因子信息相同。
若所述终端设备确定所述第一SUL载波的数量小于所述第二SUL载波的数量,则所述终端设备可以重新计算所述第一SUL载波的选择因子信息。举例来说,所述终端设备通过第一系统消息确定一个NUL载波的选择因子信息和X个第二SUL载波的选择因子信息,且一个NUL载波的选择因子值与X个第二SUL载波的选择因子值之和为1;若终端设备从X个第二SUL载波中确定出Y个第二SUL载波为第一SUL载波,则终端设备可以重新确定一个NUL载波的选择因子信息和Y个第二SUL载波的选择因子信息。在具体实施时,可以对所述一个NUL载波的选择因子信息和所述Y个第二SUL载波的选择因子信息进行归一化,得到新的NUL载波的选择因子信息和Y个第一SUL载波的选择因子信息。如,X的值为2,Y的值为1,一个NUL载波的选择因子值为0.2,2个第二SUL载波的选择因子信息的值分别是0.3和0.5,则归一化后的新的NUL载波的选择因子值为0.4,一个第一SUL载波的选择因子信息的值为0.6。
在一些实施例中,所述NUL载波的选择因子信息与所述第一SUL载波的选择因子信息相同;如,有3个第一SUL载波,则NUL载波和SUL载波的选择因子值均为0.25。或者,每个所述第一SUL载波的选择因子信息均相同,所述NUL载波的选择因子信息为1与全部所述第一SUL载波的选择因子信息之和的差;如,有4个第一SUL载波,每个SUL载波的选择因子信息均为a,NUL载波的选择因子信息为(1-4a)。或者,所述NUL载波的选择因子信息和每个所述第一SUL载波的选择因子信息相互独立;如,NUL载波的选择因子信息3个SUL载波的选择因子信息分别是0.2、0.3、0.4和0.1。
在确定第一SUL载波的选择因子信息和NUL载波的选择因子信息之后,处于Inactive或Idle状态的终端设备至少可以通过如下方案确定用于初始接入的目标载波:
1)所述终端设备以相同的概率,在所述NUL载波和全部所述第一SUL载波中随机确定一个用于初始接入的目标载波。举例来说,若有一个NUL载波和4个第一SUL载波,则NUL载波和每个第一SUL载波被确定为目标载波的概率均为25%。
2)所述终端设备基于所述NUL载波的选择因子信息和所述第一SUL载波的选择因子信息,在所述NUL载波和全部所述第一SUL载波中随机确定一个用于初始接入的目标载波。举例来说,若NUL载波的选择因子值为0.4,一个第一SUL载波的选择因子值为0.6,若随机数为0.8,而0.8属于0.6到1的区间范围,则终端设备确定第一SUL载波用于树池接入的目标载波。
3)在所述终端设备的服务小区的RSRP大于所述NUL载波对应的RSRP门限值的情况下,所述终端设备确定所述NUL载波为用于初始接入的目标载波;举例来说,第一信息还包括NUL载波对应的RSRP门限值,若所述终端设备的服务小区的RSRP大于所述NUL载波对应的RSRP门限值,所述终端设备确定所述NUL载波为用于初始接入的目标载波。在所述终端设备的服务小区的RSRP小于或等于所述NUL载波对应的RSRP门限值的情况下,所述终端设备以相同的概率,在全部所述第一补充上行载波中随机确定一个用于初始接入的目标载波;或者,所述终端设备基于所述第一补充上行载波的选择因子信息,在全部所述第一补充上行载波中随机确定一个用于初始接入的目标载 波。
4)在所述终端设备的服务小区的RSRP不小于所述NUL载波对应的RSRP门限值的情况下,所述终端设备确定所述NUL载波为用于初始接入的目标载波。举例来说,若所述终端设备的服务小区的RSRP不小于所述NUL载波对应的RSRP门限值,所述终端设备确定所述NUL载波为用于初始接入的目标载波。其中,不小于即为大于或等于;所述终端设备的服务小区的RSRP不小于所述NUL载波对应的RSRP门限值,即为所述终端设备的服务小区的RSRP大于或等于所述NUL载波对应的RSRP门限值。在所述终端设备的服务小区的RSRP小于所述正常上行载波对应的RSRP门限值的情况下,所述终端设备以相同的概率,在全部所述第一补充上行载波中随机确定一个用于初始接入的目标载波;或者,所述终端设备基于所述第一补充上行载波的选择因子信息,在全部所述第一补充上行载波中随机确定一个用于初始接入的目标载波。
本申请实施例中,网络设备通过第一系统消息向终端设备广播多个SUL载波的信息,多个SUL载波的引入可以增加通信系统的上行容量;终端设备通过随机的方式选择NUL载波或SUL载波可以降低多个终端设备选择同一个SUL载波或NUL载波的概率,能够缓解随机接入资源容量受限的问题。
2、针对所述第一信息包括所述第一SUL载波对应的RSRP门限值和/或所述第一SUL载波对应的RSRP阈值范围的情况,处于Inactive或Idle状态的终端设备至少可以通过如下方案确定用于初始接入的目标载波:
1)所述终端设备确定所述终端设备的服务小区的RSRP所属的RSRP阈值范围对应的第一SUL载波,为用于初始接入的候选载波。
在一些实施例中,RSRP阈值范围包括第一RSRP阈值和第二RSRP阈值。所述终端设备的服务小区的RSRP所属的RSRP阈值范围可以包括下述中的任意一种:第一RSRP阈值﹤所述服务小区的RSRP﹤第二RSRP阈值、第一RSRP阈值≤所述服务小区的RSRP﹤第二RSRP阈值、第一RSRP阈值﹤所述服务小区的RSRP≤第二RSRP阈值、和第一RSRP阈值≤所述服务小区的RSRP≤第二RSRP阈值。
2)所述终端设备接收网络设备发送的第二指示信息,所述终端设备根据所述第二指示信息确定用于初始接入的候选载波。
在一些实施例中,所述第二指示信息用于指示所述终端设备基于所述RSRP门限值确定用于初始接入的载波的策略;所述终端设备基于所述RSRP门限值确定用于初始接入的载波的策略,包括:
在所述终端设备的服务小区的RSRP大于所述RSRP门限值的情况下,所述RSRP门限值对应的第一补充上行载波为用于初始接入的候选载波。
或者,在所述终端设备的服务小区的RSRP不小于所述RSRP门限值的情况下,所述RSRP门限值对应的第一补充上行载波为用于初始接入的候选载波;其中,不小于即为大于或等于;所述终端设备的服务小区的RSRP不小于所述RSRP门限值,即为所述终端设备的服务小区的RSRP大于或等于所述RSRP门限值。

在具体实施时,处于连接态的终端设备可以调度终端设备在任意一个NUL载波或SUL载波上进行数据传输。在网络设备决定释放连接态的终端设备至Idle态或Inactive态的情况,网络设备可以在RRC Release消息中指示终端设备下一次触发随机接入过程使用的载波是NUL载波或SUL载波;在指示所述终端设备下一次触发随机接入过程使用的载波是SUL载波的情况下,进一步指示终端设备使用哪个SUL载波进行初始接入。在该场景下,所述第一指示信息携带于RRC Release消息 中。
