具体实施方式

值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。以下描述出于示例目的描述了新空口(New Radio，NR)系统，并且在以下大部分描述中使用NR术语，但是这些技术也可应用于NR系统应用以外的应用，如第6代(6 th Generation，6G)通信系统。
图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中，终端11也可以称作终端设备或者用户终端(User Equipment，UE)，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备(VUE)、行人终端(PUE)等终端侧设备，可穿戴式设备包括：智能手表、手环、耳机、眼镜等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12可以是基站或核心网，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点、发送接收点(Transmitting Receiving Point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。
下面对本申请实施例提供的接入方法、驻留方法、装置、用户设备及存储介质中涉及的一些概念和/或术语做一下解释说明。
1、旁链路(sidelink)
长期演进系统支持sidelink，sidelink也可以称为副链路或边链路，用于UE之间可以不通过网络设备而进行直接数据传输。
UE通过物理旁链路控制信道(Physical Sidelink Control Channel，PSCCH)发送副链路控制信息(Sidelink Control Information，SCI)，调度物理旁链路共享信道(Physical Sidelink Shared Channel，PSSCH)的传输以发送数据。该传输是以广播形式进行的，接收端并不向发送端反馈接收是否成功。
LTE sidelink设计支持两种资源分配模式，分别是调度资源分配(Scheduled resource  allocation)模式与自主资源选择(Autonomous Resource Selection)模式。前者由网络侧设备控制并为每个UE分配资源，后者由UE自主选择资源。
目前，LTE支持sidelink载波汇聚(Carrier Aggregation，CA)。LTE sidelink的CA与Uu接口(即downlink与uplink)不同，LTE sidelink的CA没有主载波(Primary component carrier，PCC)与辅载波(Secondary component carrier，SCC)之分。自主资源选择模式的UE在每个载波单元(Carrier Cell，CC)上独立进行资源感知(sensing)与资源预留。
LTE sidelink的设计可以适用于特定的公共安全事务(如火灾场所或地震等灾难场所进行紧急通讯)，或车联网(Vehicle to Everything，V2X)通信等。车联网通信包括各种业务，例如，基本安全类通信，高级(自动)驾驶，编队，传感器扩展等等。由于LTE sidelink只支持广播通信，因此主要用于基本安全类通信，其他高级V2X业务将通过新无线(New Radio，NR)sidelink支持。
第五代(the fifth generation，5G)移动通信NR系统可以用于LTE所不支持的6GHz以上工作频段，其支持更大的工作带宽，但目前版本的NR系统只支持基站(gNB)与UE间的接口，尚不支持UE之间直接通信的Sidelink接口。
具体的，ProSe网络架构中，终端与终端之间的通信接口叫PC5接口，UE与陆地无线接入网(UMTS Terrestrial Radio Access Network，UMTS E-UTRAN)等接入网设备连接的接口叫Uu接口。
2、sidelink的传输形式
目前的sidelink传输也主要分广播(broadcast)，组播(groupcast)，单播(unicast)几种传输形式。单播为一对一(即one to one)形式的传输。组播为一对多(即one to many)形式的传输。广播也是一对多(即one to many)形式的传输，但是广播并没有UE属于同一个组的概念。
目前，Sidelink单播和组播通信支持物理层混合自动重传技术(Hybrid Automatic Repeat reQuest，HARQ)的反馈机制。
目前，NR sidelink定义了两种模式(mode)，一种是mode1，基站调度资源，一种是mode2，UE自身可以决定使用什么资源进行传输，此时资源信息可能来自基站的广播消息或者预配置。若UE在基站范围内工作，并且与基站进行无线资源控制(Radio Resource Control，RRC)连接，则通过mode1和/或mode2模式进行资源传输；若UE在基站范围内工作，但未与基站进行RRC连接时，则只能工作在mode2；若UE在基站范围外，则只能工作在mode2。并且，根据预配置的信息来进行V2X传输时，mode2也可以进一步分为2a，2b，2c，2d。
3、资源池
目前V2X传输的时候有“资源池”的概念，资源池由网络侧设备发送或预配置，资源池中会包含传输所用的资源和很多传输相关的参数，如在LTE中，包括资源池第一个子帧的的偏移值、资源池对应的位图(Bitmap)、是否会在相邻无限承载(RB)传输PSCCH和PSSCH、子信道的数量和每个子信道的大小以及子信道对应的最低RB索引值、PSCCH pool对应的最低RB索引值、计算机生成的报告商品指数(Computer Build Report)测量的接收的信号强度指示(Received Signal Strength Indication，S-RSSI)门限、区域标识等等。
目前，网络侧设备给UE配置普通的传输资源池的同时，还可能会配置异常资源池(exceptional pool)，异常资源池用于一些特殊的情况，如在切换过程中，或发生无线链路失败(Radio Link Failure，RLF)，或是从空闲态(idle)向连接态(connected)态转换的过程中。
UE可以处于不同网络覆盖下，对于不同的网络，UE可以基于网络调度来选择资源池以及相应的资源，也可以基于预配置自主选择资源池。资源池的选择可能需要考虑到UE所处的区域，来选择与所处区域相关的资源池。而在自主选择资源池中的资源时，主要是 基于sensing机制来进行，也有可能是随机选择(如对于异常资源池中的资源选择)。
4、非授权频段新无线(Unlicensed band NR)
非授权频段可以作为授权频段(Licensed Band)的补充，以帮助运营商对通信服务进行扩容。为了与NR部署保持一致并尽可能的最大化基于NR的非授权接入，非授权频段可以工作在5GHz，37GHz和60GHz频段。由于非授权频段由多种技术(RATs)共用，例如无线保真(Wireless Fidelity，WiFi)，雷达，LTE授权辅助接入(Licensed-Assisted Access，LAA)等，因此在某些国家或者区域，非授权频段在使用时必须符合规范以保证所有设备可以公平的使用该资源，例如LBT，最大信道占用时间(Maximum Channel Occupancy Time，MCOT)等规则。
5、先听后说(LBT)
工作于非授权的频段的发送端在发送信号之前需要监听该频带(可以由中心频点+带宽标识)是否被占用，如果没有被占用，则发送端可以在该频带进行信号的发送。
6、RRC建立条件(Connection Establishment Condition)
在sidelink中，有一种情况V2X sidelink传输时会触发UE进入RRC连接态，即IDLE UE在要进行V2X sidelink相关通信过程时，系统消息中包含了V2X的相关配置却没有包含资源相关信息(如资源池)。
7、NR RRC的三个状态
处于Idle态的UE，在网络侧设备上没有RRC上下文，也就是说网络侧设备与UE之间通信所必须的参数不属于某个特定的小区,网络侧设备也不知道是否存在该UE。UE在所处追踪区域(Tracking Area，TA)被分配了一个唯一的标识。从核心网的角度来看，该设备处于CN_IDLE状态。为了减少耗电，UE在大部分时间处于休眠状态，因此无法进行数据传输。在下行链路中，处于Idle态的UE可周期性地唤醒以从网络接收寻呼消息。移动性(Mobility)可由UE进行小区重选来处理。在Idle态，UE与网络侧设备不会保持上行同步，如果要从Idle态转入Connected态，只能通过随机接入(Random Access)，在UE与网络侧设备建立RRC上下文。
在RRC_Connected态，可建立RRC上下文，且通信所需的所有参数对于两个实体(UE与网络侧设备)都是已知的。从核心网的角度来看，UE处于CN_Connected状态。UE所属的小区是已知的，并且已经配置了用于设备和网络之间的传输信令目的设备标识，即小区无线网络临时标识符(C-RNTI)。连接态可传输数据，但由于包的数据流通常是突发的，在没有数据流传输的时候，可以通过关闭UE的接收电路来降低功耗，采用不连续接收(Discontinuous Reception，DRX)技术。由于在连接态下已在gNB中建立了RRC上下文，因此离开DRX并开始接收/发送数据相对较快。在连接态，移动性(Mobility)可由网络侧设备处理，即UE向网络提供邻小区测量，网络命令设备进行切换(handover)。上行时间同步可能存在也可能不存在，当有数据要传输时，可通过使用随机接入去建立和保持上行同步。在LTE中，仅支持空闲态和连接态。实际中的常见情况是使用空闲态作为UE的主要睡眠状态来省电。然而，由于在一些智能手机中常常存在小数据包的频繁传输，如果按照LTE方式，会存在大量的空闲态到连接态的转换。这些转换增加了信令负载和信令延时。因此，为了减少信令负载和等待时间，在NR中引入了非激活态(RRC_INACTIVE)状态。
在RRC_INACTIVE态，保持了网络侧设备与UE侧的RRC上下文。从核心网的角度来看，UE处于CN_Connected状态。因此从非激活态转换到连接态的速度很快，且不需要核心网信令。同时，允许UE以空闲态类似的方式休眠，并且通过小区重选来处理移动性。因此，RRC_INACTIVE可以被视为空闲和连接状态的混合。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的接入方法进行详细地说明。
目前，在LTE V2X中，网络侧设备可以通过配置对UE的资源进行调控，并且可以控制UE进入连接态的实际，以便于后续UE请求传输资源等目的。在非授权频段上，sidelink UE可能不再基于资源池配置来进行数据传输，此时网络侧设备通过何种配置来控制空闲态或非激活态的UE何时可以进入连接态，尚不清楚(即问题1)。此外，对于空闲态或非激活态的UE，网络侧设备如何调整UE在非授权频段上的驻留情况，也不清楚(即问题2)。
针对问题1，本申请实施例提供一种接入方法，UE可以根据目标信息，灵活的确定是否进入连接态，即UE可以基于非授权频段的相关信息，判断是否进行连接建立，从而实现对空闲态或非激活态的UE的状态转换情况进行灵活的调控。
针对问题2，本申请实施例提供一种驻留方法，UE可以根据目标信息，灵活的确定UE在小区选择或重选过程中待驻留的频点，即UE可以基于非授权频段的相关信息，进行小区/频点的驻留，从而实现对UE的小区选择或重选过程中驻留情况进行灵活的调控。
实施例一
本申请实施例提供一种接入方法，图2示出了本申请实施例提供的一种接入方法的流程图。如图2所示，本申请实施例提供的接入方法可以包括下述的步骤201和步骤202。
步骤201、UE获取目标信息。
可选地，本申请实施例中，上述目标信息可以为网络侧设备配置的、预配置的、预定义的、协议约定的或UE自主决定的等。
可选地，本申请实施例中，网络侧设备可以对处于空闲态和非激活态UE的行为进行调控，并向UE发送目标信息。
步骤202、UE根据目标信息，确定是否进入连接态。
本申请实施例中，上述目标信息包括以下至少一项：非授权频段的相关配置信息、UE的业务需求信息、LBT信息、第一指示信息。其中，LBT信息用于指示UE是否发生连续的LBT失败；第一指示信息用于指示网络侧设备是否支持在非授权频段上进行感知或资源选择。
本申请实施例中，UE可以根据目标信息(即非授权频段的相关信息)，确定是否触发建立RRC连接，以确定UE是否从非激活态或空闲态进入连接态。
需要说明的是，上述非授权频段的相关配置信息可以理解为：网络侧设备为UE配置的与非授权频段相关的信息，以用于UE确定是否进入连接态。
需要说明的是，上述感知或资源选择为：若基站启用工作于免许可频段的5G空中接口(NewRadio in Unlicensed Spectrum，NR-U)，则说明基站支持在非授权频段上进行感知或资源选择，此时UE可以触发建立RRC连接，并进入连接态，或模式1的调度具有较好性能；若基站不支持感知或资源选择，模式1的调度为盲调度，则UE可以不触发建立RRC连接。
可选地，本申请实施例中，上述步骤202具体可以通过下述的步骤202a实现。
步骤202a、在网络侧设备的配置信息中包括旁链路的相关配置信息、且不包括旁链路的传输资源信息的情况下，UE根据目标信息，确定是否进入连接态。
本申请实施例中，上述旁链路的传输资源信息为用于旁链路传输的资源信息，该传输资源信息可以包括以下至少一项：普通资源池和异常资源池。
本申请实施例中，当网络侧设备配置中包括了sidelink相关的配置信息而没有包括用于sidelink传输的资源信息，UE可以基于网络侧设备配置和/或sidelink传输是否发生在非授权频段来决定是否触发RRC连接建立，或者当网络侧设备配置中包括了sidelink相关的配置信息而没有包括用于sidelink传输的资源信息，UE还可以基于在非授权频段的传输情况即自身的LBT成功或失败情况来决定是否触发RRC连接建立，因此，旁链路传输中网络侧设备可以通过配置来对空闲态或非激活态的UE的状态转换或驻留情况进行灵活的调 控，以使得在非授权频段上实现更好的网络侧设备与UE间的协作和控制。
可选地，本申请实施例中，UE还可以在网络侧设备配置中不包括旁链路相关的配置信息的情况下，根据目标信息，确定是否触发建立RRC连接，以确定是否进入连接态；或者，UE还可以在网络侧设备配置中不包括用于旁链路传输的资源信息(普通资源池和/或异常资源池)时，根据目标信息，确定是否触发建立RRC连接，以确定是否进入连接态；或者，UE还可以在网络侧设备配置中既没有包括旁链路相关的配置信息，也没有包括用于旁链路传输的资源信息(普通资源池和/或异常资源池)时，根据目标信息，确定是否触发建立RRC连接，以确定是否进入连接态；或者，UE还可以在网络侧设备配置中包括用于旁链路传输的资源信息(普通资源池和/或异常资源池)，但没有包括旁链路相关的配置信息时，根据目标信息，确定是否触发建立RRC连接，以确定是否进入连接态。
可选地，在本申请实施例的第一种实现方式中，上述目标信息包括非授权频段的相关配置信息，上述步骤202具体可以通过下述的步骤202b和步骤202c实现。
步骤202b、UE接收网络侧设备发送的第二指示信息。
本申请实施例中，上述第二指示信息中包括非授权频段的相关配置信息，第二指示信息用于指示是否允许或需要UE在非授权频段进行旁链路传输。
步骤202c、UE根据第二指示信息，确定是否触发建立RRC连接。
本申请实施例中，UE可以在获取到接收网络侧设备发送的非授权频段的相关配置信息之后，基于该非授权频段的相关配置信息，确定是否触发建立RRC连接，以确定是否进入连接态。
示例性地，若UE收到网络侧设备指示1bit，其值为1时触发建立RRC连接，以进入连接态，为0时不触发建立RRC连接；或者，其值为0时触发建立RRC连接，以进入连接态，为1时不触发建立RRC连接。
本申请实施例中，在非授权频段上，旁链路传输中网络侧设备可以通过配置来对空闲态或非激活态的UE的状态转换情况进行灵活的调控，以使得在非授权频段上实现更好的网络侧设备与UE之间的协作和控制。
