  • the present application relates to the field of communications, and more particularly, to an uplink transmission method, a terminal device, and a network device.

  • transmission resources used for UL transmission and related transmission parameters for example, time domain resources, frequency domain resources, spatial domain resources, and modulation and coding schemes used for UL transmission (Modulation) And Coding Scheme, MCS), etc.
  • the UE when the UE needs to send uplink data, the UE sends a scheduling request to the base station, and the base station sends a scheduling authorization to the UE according to the scheduling request. Then, the UE performs UL transmission according to the transmission resource indicated in the scheduling grant and related transmission parameters. If the UE is in the Radio Resource Control (RRC) idle state (RRC_IDLE) state, the UE first needs to perform random access before transmitting data. In the random access process, four messages need to be exchanged between the base station and the UE. .

  • the data generated by the mMTC service is usually small data (that is, each packet of the service is relatively small, also called packet transmission).
  • the traditional Grant-based UL transmission method is adopted, the transmission resource occupied by the data transmission is much smaller than the data transmission.
  • the transmission resources occupied by the previous signaling interaction for example, the signaling interaction of the scheduling request and the scheduling authorization process, or the signaling interaction of the random access procedure, which results in low utilization of the transmission resources, especially in the presence of a large number of mMTCs.
  • the system resources are largely occupied by the interactive signaling; the URLLC service requires low latency and belongs to the delay-sensitive service, and the signaling interaction in the UL transmission process is performed by the Grant-based transmission method, because the RRC letter is involved. Therefore, the delay is very large, so the traditional Grant-based UL transmission is difficult to meet the needs of the URLLC service.
  • 5G mobile communication technology introduces a transmission mode of Grant-free transmission (also referred to as unscheduled transmission) in the New Radio (NR) system for UL transmission.
  • Grant-free transmission means that the UE does not need to request the UL transmission resource from the base station when the data needs to be transmitted, but selects a transmission resource for the UL transmission based on a certain rule in the Grant-free transmission resource pool pre-configured by the base station.
  • Direct UL transmission lose. In this way, the signaling interaction in the Grant-based UL transmission process can be omitted, thereby reducing signaling overhead and transmission delay, and is particularly suitable for packet transmission and delay sensitive services.

Description

上行传输方法、终端设备和网络设备
本申请要求于2017年7月17日提交中国专利局、申请号为201710582362.X、申请名称为“一种数据传输方法和设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，并且更具体地，涉及一种上行传输方法、终端设备和网络设备。
背景技术
传统的蜂窝通信系统，例如长期演进(Long Term Evolution，LTE)系统中，上行(Uplink，UL)传输采用基于授权(Grant-based)传输方式。即，基站为用户设备(User Equipment，UE)调度进行UL传输所使用的传输资源以及相关的传输参数，例如，UL传输所使用的时域资源、频域资源、空域资源以及调制编码方案(Modulation and Coding Scheme，MCS)等。
具体地，当UE有上行数据需要发送时，UE向基站发出调度请求，基站基于调度请求向UE发送调度授权。然后，UE根据调度授权中所指示的传输资源以及相关的传输参数进行UL传输。如果UE本身处于无线资源控制(Radio Resource Control，RRC)空闲(RRC_IDLE)状态，则UE首先还需要进行随机接入然后才能传输数据，随机接入过程中基站和UE之间需要进行四条消息的交互。综上所述，上述Grant-based传输方式，在数据传输之前需要较多的信令开销，这些信令交互不可避免地会带来延迟。
目前，第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)正在制定第五代(5th Generation，5G)移动通信技术的标准。5G移动通信技术适用的场景中包括海量机器类型通信(massive Machine Type Communication，mMTC)业务和超可靠低延迟通信(Ultra-Reliable and Low Latency Communications，URLLC)业务。mMTC业务产生的数据通常是小数据(即业务的每个数据包比较小，也称为小包传输)，如果采用传统Grant-based的UL传输方式，则数据传输所占用的传输资源远小于数据传输之前的信令交互(例如，调度请求和调度授权过程的信令交互，或者，随机接入过程的信令交互)所占用的传输资源，这导致传输资源利用率低下，特别是在有大量mMTC设备的情况下，系统资源将大量地被交互信令所占用；URLLC业务要求低延迟，属于延迟敏感业务，而通过上述Grant-based传输方式进行UL传输过程中的信令交互，由于涉及RRC信令，其延迟是很大的，因此传统的Grant-based的UL传输很难满足URLLC业务的需求。
基于上述原因，5G移动通信技术在新无线(New Radio，NR)系统中引入了免授权(Grant-free)传输(也称作免调度传输)的传输方式，用于UL传输。所谓Grant-free传输，是指UE有数据需要传输时无需向基站请求UL传输资源，而是在基站预先配置的Grant-free传输资源池中基于某种规则选择一个用于UL传输的传输资源，直接进行UL传 输。这样，就可以省去Grant-based的UL传输过程中的信令交互，从而降低了信令开销和传输延迟，特别适合于小包传输以及延迟敏感业务。
目前，5G移动通信技术的NR标准已经明确同意mMTC和URLLC支持Grant-free传输。另外，5G移动通信技术的NR标准还确定由基站配置Grant-free传输所使用的时频资源，即配置Grant-free传输资源池。
由于UE的数据包何时需要传输是不确定的，所以同一时刻有多少UE需要进行Grant-free传输也是不确定的。这导致系统静态配置Grant-free传输资源池时难以确定其大小。如果配置的Grant-free传输资源池较大，则当需要进行Grant-free传输的UE较少时，所配置的Grant-free传输资源会因大量闲置而造成资源浪费。同时，配置太大的Grant-free传输资源池，也会挤占其他采用Grant-based传输方式的业务的传输资源，从而对这些业务的传输造成影响。如果配置的Grant-free传输资源池较小，则当有较多UE需要进行Grant-free传输时，不同UE的传输数据碰撞严重，会极大地降低Grant-free传输性能，造成传输资源的浪费和传输资源利用效率低下。总之，传输业务量的不确定性可能导致Grant-free传输资源池的传输资源利用效率低下。

应理解，在本申请实施例中，网络设备可以与终端设备进行数据传输，网络设备为终端设备分配传输资源。从产品形态上来看，网络设备是具有中心控制功能的设备，例如宏基站、微基站、热点(pico)、家庭基站(Femeto)、传输点(Transmission Point，TP)、中继(Relay)站、AP等；终端设备是能够接收网络设备调度和指示信息的设备，例如手机、电脑、手环、智能手表、数据卡、传感器、站点(Station，STA)等。对于副链路(sidelink)即设备对设备(Device to Device，D2D)，例如，手环-手机-基站中手环与手机之间的链路，手环可视为终端设备，而手机视为网络设备。
此外，LTE系统或NR系统中的载波上可以同时有多个小区同频工作，在某些特殊场景下，也可以认为上述载波与小区的概念等同。例如，在载波聚合(Carrier Aggregation，CA)场景下，当为终端设备配置辅载波时，会同时携带辅载波的载波索引和工作在该辅载波的辅小区的小区标识(Cell Indentify，Cell ID)，在这种情况下，可以认为载波与小区的概念等同，例如终端设备接入一个载波和接入一个小区是等同的。

下面对本申请涉及的一些概念和技术进行简单的介绍。
免调度传输：
5G移动通信技术的NR系统中存在多种业务类型，不同的业务类型对应不同的业务需求，因此NR系统中引入了免调度(Grant-free or Grant-less)传输，又称为免授权传输。在本申请各实施例中，免调度传输可以理解为如下的任意一种或多种含义，或者理解为如下的多种含义中的部分技术特征的组合或其他类似含义。
免调度传输可以指：网络设备预先分配并告知终端设备多个传输资源；终端设备有上行数据传输需求时，从网络设备预先分配的多个传输资源中选择至少一个传输资源，使用所选择的传输资源发送上行数据；网络设备在所述预先分配的多个传输资源中的一个或多个传输资源上检测终端设备发送的上行数据。所述检测可以是盲检测，也可能根据所述上行数据中某一个控制域进行检测，或者是其他方式进行检测。
免调度传输可以指：网络设备预先分配并告知终端设备多个传输资源，以使终端设备有上行数据传输需求时，从网络设备预先分配的多个传输资源中选择至少一个传输资源，使用所选择的传输资源发送上行数据。
免调度传输可以指：获取预先分配的多个传输资源的信息，在有上行数据传输需求时，从所述多个传输资源中选择至少一个传输资源，使用所选择的传输资源发送上行数据。获取的方式可以从网络设备获取或预先定义。
免调度传输可以指：不需要网络设备动态调度即可实现终端设备的上行数据传输的方法，所述动态调度可以是指网络设备为终端设备的每次上行数据传输通过信令来指示传输资源的一种调度方式。可选地，实现终端设备的上行数据传输可以理解为允许两个或两个以上终端设备的数据在相同的时频资源上进行上行数据传输。可选地，所述传输资源可以是终端设备接收所述信令的时刻以后的一个或多个时域资源的传输资源。
免调度传输可以指：终端设备在不需要网络设备授权的情况下进行上行数据传输。所述授权可以指终端设备发送上行调度请求给网络设备，网络设备接收调度请求后，向终端设备发送上行授权，其中所述上行授权指示分配给终端设备的上行传输资源。
免调度传输可以指：一种竞争传输方式，具体地可以指多个终端在预先分配的相同的时频资源上同时进行上行数据传输，而无需基站进行授权。
基于调度(Grant-based)传输的流程：
Grant-based传输是蜂窝通信系统中的传统的UL上行传输方式。具体流程为，当终端设备有数据需要传输时，需要首先向网络设备发出调度请求，例如，发送自己的缓存大小报告(Buffer Size Report，BSR)，其中，BSR用于上报终端设备有多少数据需要传输；然后终端设备等候网络设备发送的调度授权，对于上行传输而言可以为上行授权(UL Grant)；终端设备在UL Grant所配置的传输资源上传输UL数据。在终端设备报告自己的BSR之前，终端设备可能还需要通过随机接入过程获取定时提前量(Timing Advance，TA)。
高层信令：
高层信令可以指高层协议层发出的信令，高层协议层为物理层以上的每个协议层中的至少一个协议层。其中，高层协议层具体可以为以下协议层中的至少一个：媒体接入控制(Medium Access Control，MAC)层、无线链路控制(Radio Link Control，RLC)层、分组数据会聚协议(Packet Data Convergence Protocol，PDCP)层、无线资源控制(Radio Resource Control，RRC)层和非接入层(Non Access Stratum，NAS)等。
对于前文中提到的Grant-free传输资源池的传输资源利用效率低下的问题，一种解决方法是网络设备动态调整Grant-free传输资源池的大小。但是，由于NR系统仍是以基于授权(Grant-based)传输为主的通信系统，Grant-free传输资源可能只会占据少量资源，如果频繁进行Grant-free传输资源池的重配置，显然会带来较大的信令开销。
针对上述问题，本申请实施例提供了一种上行传输方法，网络设备配置相对固定的Grant-free传输资源池且不轻易对其进行重配置。通过接入控制(Admission Control或Access Control)，使得网络设备控制采用Grant-free传输方式的终端设备的数量或者业务量，从而使得系统对Grant-free传输资源的利用更加有效。
图2是本申请一个实施例的上行传输方法200的示意性流程图。如图2所示，上行传输方法200包括以下步骤。
S210，网络设备生成接入控制信息，所述接入控制信息用于指示终端设备确定传输数据所采用的传输方式，所述传输方式包括免调度Grant-free传输方式或基于授权Grant-based传输方式。
S220，网络设备发送接入控制信息，相对应地，终端设备接收网络设备发送的接入控制信息。
S230，终端设备根据确定的传输方式进行上行传输。
本申请实施例的上行传输方法，网络设备为终端设备配置接入控制信息，以控制终端设备通过Grant-free传输方式或Grant-based传输方式传输数据，可以提高Grant-free传输资源的利用效率。
本申请实施例中，接收接入控制信息的终端设备，其接收的接入控制信息中可能包括直接用于指示该终端设备是否采用Grant-free传输方式的信息，也可以不包括直接用于指示该终端设备是否采用Grant-free传输方式的信息，而是暗指接收接入控制信息的该终端设备是否采用Grant-free传输方式。
应理解，本申请实施例的终端设备可以采用Grant-free传输方式传输数据，或者可以采用Grant-based传输方式传输数据。终端设备从Grant-free传输方式和Grant-based传输方式中选取一种用于上行传输；或者更具体的，终端设备从Grant-free传输方式和Grant-based传输方式中选取一种用于传输目标业务。
网络设备为终端设备配置接入控制信息，当终端设备有数据需要传输时，基于网络设备所配置的接入控制信息，确定是否采用Grant-free传输方式传输数据。如果终端设备确定不采用Grant-free传输方式传输数据，则采用Grant-based传输方式传输数据。换句话说，当终端设备有数据需要传输时，基于网络设备配置的接入控制信息确定传输方式，传输方式包括Grant-free传输方式和Grant-based传输方式。
终端设备在上行传输中，在Grant-free传输时使用网络设备配置的Grant-free传输资源，在Grant-based传输时使用网络设备调度的Grant-based传输资源。在进行Grant-free 传输之前，网络设备需要为终端设备配置Grant-free传输资源。假设网络设备配置Grant-free传输资源的消息为第一消息(其中可能包括一条或多条信令)，配置接入控制信息的消息为第二消息，则第一消息和第二消息可以为同一消息；第一消息和第二消息也可以为不同的消息，并且第一消息和第二消息可以以任意的先后顺序发送，即第一消息和第二消息的发送无先后顺序要求。
可选地，S220中网络设备发送所述接入控制信息，可以包括：网络设备通过广播、组播或单播的方式发送接入控制信息。相对应地，终端设备接收网络设备发送的接入控制信息，可以包括：终端设备接收网络设备通过广播、组播或单播的方式发送的接入控制信息。具体而言，在接入控制信息用于指示多个终端设备传输数据所采用的传输方式的情况下，网络设备可以通过广播或组播的方式向该多个终端设备发送接入控制信息；在接入控制信息用于指示一个终端设备传输数据所采用的传输方式的情况下，网络设备可以通过单播的方式向该终端设备发送接入控制信息。下文中，将会结合接入控制信息的具体形式，说明接入控制信息的发送方式。
在本申请实施例中，网络设备可以通过系统消息，例如，主信息块(Master Information Block，MIB)或系统信息块(System Information Block，SIB)，向至少一个终端设备发送接入控制信息。网络设备还可以通过高层信令向至少一个终端设备发送接入控制信息，例如，RRC信令、MAC信令(具体可以为MAC控制单元(MAC Control Element，MAC CE))或寻呼(paging)消息等。网络设备还可以通过物理层信令向至少一个终端设备发送接入控制信息，例如通过下行控制信息(Downlink Control Information，DCI)或组公共DCI(group common DCI)来配置。DCI和group common DCI可以由物理下行控制信道(Physical Downlink Control CHannel，PDCCH)承载。
网络设备可以通过上述方式中任何一种方式对配置的接入控制信息进行修改，即对接入控制信息进行重配置。
需要说明的是，S230中与终端设备进行上行传输的网络设备与S220发送接入控制信息的网络设备可以是相同的网络设备也可以是不同的网络设备。具体而言，第一网络设备向终端设备发送接入控制信息(为终端设备配置接入控制信息)，用于终端设备进行UL传输时传输方式的选择。终端设备使用选定的传输方式(Grant-free传输方式或Grant-based传输方式)传输数据，数据的接收端可以是第一网络设备，有可以不是第一网络设备，而是第二网络设备。例如，在异构网络中，第一网络设备可以是宏基站，第二网络设备可以是微基站，即宏基站为终端设备配置接入控制信息，而该接入控制信息用于终端设备与微基站之间UL传输时的传输方式选择。类似地，在中继(relay)场景中，第一网络设备可以是eNB，第二网络设备可以是中继站。
还需要说明的是，本申请实施例的接入控制信息可以用于指示具备Grant-free传输能力的终端设备，也可以用于指示接入系统的所有终端设备，本申请实施例对此不作限定。终端设备基于接入控制信息确定传输方式，仅适用于允许采用Grant-free传输方式的业务。例如，假设标准、协议或系统规定eMBB业务不允许采用Grant-free传输方式进行数据传输，则当终端设备传输eMBB业务时忽略接入控制信息，而直接使用Grant-based传输方式进行数据传输。
应理解，接入控制信息可以是发送给至少一个终端设备的，其可以用于指示至少一个 终端设备确定传输数据所采用的传输方式。至少一个终端设备根据接入控制信息确定传输数据所采用的传输方式的结果可以是，至少一个终端设备中的一部分终端设备采用Grant-free传输方式，至少一个终端设备中的另外一部分终端设备采用Grant-based传输方式；或者，至少一个终端设备中所有的终端设备均采用Grant-free传输方式；或者，至少一个终端设备中所有的终端设备均采用Grant-based传输方式，本申请实施例对此不作限定。
在本申请实施例中，接入控制信息可以用于指示采用Grant-free传输方式和/或采用Grant-based传输方式的特定的终端设备。具体地，可以采用直接指示终端设备的标识，也可以采用指示条件的方式，或是采用其他的指示方式，本申请实施例对此不作限定。
可选地，接入控制信息用于指示采用Grant-free传输方式的第一终端设备，和/或，用于指示采用Grant-based传输方式的第二终端设备。其中，第一终端设备包括至少一个终端设备和/或第二终端设备包括至少一个终端设备。本实施例中，网络设备直接指示哪些终端设备可以采用Grant-free传输方式和/或指示哪些终端设备可以采用Grant-based传输方式，从而达到控制在有限的Grant-free传输资源上进行传输的终端设备的数量的目的，提高Grant-free传输资源的利用效率。
对于小区中具备Grant-free传输能力的终端设备或者对于小区中的所有终端设备，网络设备可以将其分为两组。第一组终端设备被允许使用Grant-free传输方式进行上行传输，第一组终端设备也可以认为是第一终端设备；第二组终端设备只被允许使用Grant-based传输方式进行上行传输，第二组终端设备也可以认为是第二终端设备。网络设备将哪些终端设备划分为第一组终端设备，由网络设备内部实现决定。例如，在当前Grant-free传输资源碰撞比较严重的情况下，网络设备可将较少的终端设备划分为第一组终端设备；在当前Grant-free传输资源的空置率较高的情况下，网络设备可将较多的终端设备划分为第一组终端设备。再如，在Grant-based传输资源的负载较重的情况下，网络设备可以将较多的终端设备划分为第一组终端设备，以使部分业务转移到Grant-free传输资源上来，从而减轻Grant-based传输资源的负载；在Grant-based传输资源的负载较轻的情况下，网络设备可以将较少的终端设备划分为第一组终端设备。当然，网络设备也可以综合考虑Grant-free传输资源的负载和Grant-based传输资源的负载，或者参考其他参数来确定第一组终端设备。
换句话说，接入控制信息可以用于指示第一组终端设备，相当于网络设备指示了可以使用Grant-free传输方式的终端设备的白名单；而接入控制信息可以用于指示第二组终端设备，相当于网络设备指示了可以使用Grant-free传输方式的终端设备的黑名单；或者接入控制信息包括以上两者。
例如，第一组终端设备只被允许使用Grant-free传输方式进行上行传输(即禁止第一组终端设备使用Grant-based传输方式进行上行传输)；第二组终端设备只被允许使用Grant-based传输方式进行上行传输(即禁止第二组终端设备使用Grant-free传输方式进行上行传输)。接入控制信息可以用于指示第一组终端设备，即用于指示仅可以采用Grant-free传输方式的终端设备。当终端设备判断自己属于接入控制信息所指示的第一组终端设备时，则采用Grant-free传输方式进行上行传输；当终端设备判断自己不属于接入控制信息所指示的第一组终端设备时，则认为自己属于第二组终端设备，即不可使用 Grant-free传输方式，而只能使用Grant-based传输方式进行上行传输。接入控制信息可以用于指示第二组终端设备，即用于指示仅可以采用Grant-based传输方式的终端设备；或者，接入控制信息可以用于分别指示第一组终端设备采用Grant-free传输方式及第二组终端设备采用Grant-based传输方式，本申请实施例对此不作限定。
再如，第一组终端设备可采用Grant-free传输方式或Grant-based传输方式(由终端设备自己决定采用哪种传输方式)进行上行传输，第二组终端设备只被允许使用Grant-based传输方式进行上行传输(即禁止第二组终端设备使用Grant-free传输方式进行上行传输)。接入控制信息可以用于指示第一组终端设备，即用于指示既允许采用Grant-free传输方式又允许采用Grant-based传输方式的终端设备。当终端设备判断自己属于接入控制信息所指示的第一组终端设备时，则根据自身的情况或条件，确定采用Grant-free传输方式或是Grant-based传输方式进行上行传输；当终端设备判断自己不属于接入控制信息所指示的第一组终端设备时，则认为自己属于第二组终端设备，即不可使用Grant-free传输方式，而只能使用Grant-based传输方式进行上行传输。接入控制信息可以用于指示第二组终端设备，即用于指示仅可以采用Grant-based传输方式的终端设备；或者，接入控制信息可以用于分别指示第一组终端设备既允许采用Grant-free传输方式又允许采用Grant-based传输方式，及第二组终端设备采用Grant-based传输方式，本申请实施例对此不作限定。
具体地，接入控制信息可以有多种可能的实现方式。
例如，接入控制信息可以包括用于指示采用Grant-free传输方式的第一终端设备(即第一组终端设备)的标识，和/或，用于指示采用Grant-based传输方式的第二终端设备(即第二组终端设备)的标识。接入控制信息可以包括第一组终端设备中的终端设备的标识的列表，不在该列表中的终端设备不能使用Grant-free传输方式进行上行传输；或者，接入控制信息可以包括第二组终端设备中的终端设备的标识的列表，在该列表中的终端设备不能使用Grant-free传输方式进行上行传输；或者，接入控制信息可以包括第一组终端设备中的终端设备的标识的列表和/或第二组终端设备中的终端设备的标识的列表。接入控制信息采用标识列表的形式，不论是网络设备还是终端设备均较为简单，且容易解析。本实施例的接入控制信息可以通过广播或组播的方式向多个终端设备发送。
再如，接入控制信息可以包括用于指示采用Grant-free传输方式的第一终端设备和/或采用Grant-based传输方式的第二终端设备的位图。接入控制信息可以包括用于指示采用Grant-free传输方式的第一终端设备(第一组终端设备)的位图(bitmap)。位图中每个比特代表一个终端设备，每个比特的取值代表该终端设备是否属于第一组终端设备，例如，取值1(也可以取其他值)代表该终端设备属于第一组终端设备，取值0(也可以取其他值)代表该终端设备不属于第一组终端设备。或者，接入控制信息可以包括用于指示采用Grant-based传输方式的第二终端设备(第二组终端设备)的位图。位图中每个比特代表一个终端设备，每个比特的取值代表该终端设备是否属于第二组终端设备，例如，取值1(也可以取其他值)代表该终端设备属于第二组终端设备，取值0(也可以取其他值)代表该终端设备不属于第二组终端设备。应理解，在只有Grant-based传输方式和Grant-free传输方式两种传输方式的情况下，位图可以同时指示第一终端设备和第二终端设备。接入控制信息中可能还需要携带起始终端设备的标识，即位图中第一比特所指示的终端设备的标识。接入控制信息采用位图的形式，可以节省开销。本实施例的接入控制信息可以通过 广播或组播的方式向多个终端设备发送。
又如，接入控制信息可以包括用于指示一个终端设备(即所讨论的目标终端设备)是采用Grant-free传输方式或是采用Grant-based传输方式的位图。该实施例是上一实施例的一个特例，即位图的长度为1比特的情况。一个具体的例子中，该比特的取值为1时该终端设备采用Grant-free传输方式传输数据，该终端设备属于第一终端设备；该比特的取值为0时该终端设备采用Grant-based传输方式传输数据，该终端设备属于第二终端设备。上一实施例的接入控制信息可以通过广播或组播的方式发送，而本实施例的接入控制信息由于是针对一个终端设备的，因此可以携带在用户消息中发送给目标终端设备。
又如，接入控制信息可以用于指示允许采用Grant-free传输方式的终端设备满足的第一条件或用于指示不允许采用Grant-free传输方式的终端设备满足的第二条件。接入控制信息可以包括第一条件，第一条件可以是一组过滤条件，其中包括至少一个过滤条件。当终端设备判断自身符合第一条件时，则认为自己属于第一组终端设备，采用Grant-free传输方式；否则终端设备不属于第一组终端设备。具体地，例如，第一条件可以包括，终端设备的终端设备标识(IDentity，ID)为奇数；再如，第一条件可以包括，终端设备的终端设备标识模N等于m，N和/或m可以是标准预定义的，或者网络设备事先配置的，或者直接在接入控制信息中指示的；再如，第一条件可以包括，终端设备测得的网络设备功率(例如终端设备基于网络设备的同步信号或参考信号测量的结果)大于第一阈值，第一阈值可以是标准预定义的，或者网络设备事先配置的，或者直接在接入控制信息中指示的；再如，第一条件可以包括，终端设备要传输的数据量(即BSR)小于第二阈值，第二阈值可以是标准预定义的，或者网络设备事先配置的，或者直接在接入控制信息中指示的；再如，第一条件可以包括，终端设备要发送的数据对延时的要求小于第三阈值，第三阈值可以是标准预定义的，或者网络设备事先配置的，或者直接在接入控制信息中指示的。
应理解，第一条件可以是上述单独的条件，也可以是多个条件的组合，本申请实施例对此不作限定。还应理解，类似地，接入控制信息可以包括第二条件，当终端设备判断自身符合第二条件时，则认为自己不属于第一组终端设备，不能采用Grant-free传输方式，此处不再进行赘述。当终端设备数量特别大时，本实施的方案比直接指示终端设备的标识的方案和指示位图的方案，所使用的指示开销更小。
应理解，在系统只有Grant-based传输方式和Grant-free传输方式两种传输方式的情况下，接入控制信息对两种中的任一种进行指示实际上是等效的。
对于直接指示终端设备的标识、指示位图(多比特)以及指示条件的方案，网络设备可以通过广播消息、组播消息或多播消息来承载接入控制信息以通知终端设备，例如承载在系统消息(MIB或SIB)、广播或多播RRC信令、广播或多播MAC CE或广播或多播物理层信令(例如，group common DCI)中；当然，网络设备也可以使用单播的终端设备消息来承载接入控制信息以通知每个终端设备，例如通过DCI、Paging消息、单播RRC信令或单播MAC CE等承载。对于1比特位图的方案，网络设备可以使用单播的终端设备消息来承载接入控制信息以通知每个终端设备，例如通过DCI、Paging消息、单播RRC信令或单播MAC CE等承载。
可选地，接入控制信息可以用于指示终端设备使用Grant-free传输方式的概率。具体而言，接入控制信息可以包括第一概率信息，第一概率信息用于指示终端设备采用 Grant-free传输方式的概率或采用Grant-based传输方式的概率。这里，称第一概率信息指示的信息为第一概率。前述几个实施例中，某些终端设备支持Grant-free传输能力，但却不允许使用Grant-free传输方式，本实施例可以避免前述实施例所导致的对部分终端设备不公平的问题，各终端设备均有使用Grant-free传输方式的概率。
对于小区中具备Grant-free传输能力的终端设备，网络设备可指示每个终端设备传输数据时采用Grant-free传输方式的概率。终端设备在每次传输数据时，根据网络设备所指示的Grant-free传输方式的概率确定本次传输是否采用Grant-free传输方式进行传输。终端设备下次传输时，重新根据网络设备所指示的Grant-free传输方式的概率确定是否采用Grant-free传输方式，即终端设备两次传输数据是否采用Grant-free传输方式的判决是不相关的。
网络设备配置给终端设备的接入控制信息可以是第一概率(记为α)，第一概率用于指示终端设备采用Grant-free传输方式的概率。换句话说，终端设备每次传输时，以概率α选择使用Grant-free传输方式，以概率1-α选择使用Grant-based传输方式。具体实现上，终端设备可以在每次传输时，从(0，1)范围内随机取一个值(记为λ)，当λ<α时，终端设备使用Grant-free传输方式；当λ>α时，终端设备使用Grant-based传输方式。第一概率可以用若干比特来指示。表1是第一概率用3bits表示的一个例子，表1给出了第一概率的比特表示与实际概率值之间的对应关系。应理解，第一概率也可以以更粗的粒度来划分，则需要更少的比特来表示，或者第一概率也可以以更细的粒度来划分，则需要更多的比特来表示，本申请实施例对此不作限定。

网络设备配置给终端设备的接入控制信息中的第一概率(记为α)可以用于指示终端设备不采用Grant-free传输方式的概率，即指示终端设备采用Grant-based传输方式的概率。换句话说，终端设备每次传输时，以概率α选择使用Grant-based传输方式，以概率1-α选择使用Grant-free传输方式。
在只有Grant-based传输方式和Grant-free传输方式两种传输方式的情况下，上述两种指示方式实际上是等效的。
网络设备为终端设备配置的第一概率的取值由网络设备决定，是网络设备的内部实现。例如，在第一概率用于指示终端设备采用Grant-free传输方式的概率的情况下，如果当前Grant-free传输资源碰撞比较严重，网络设备可配置较小的第一概率；如果当前Grant-free传输资源的空置率较高，则网络设备可配置较大的第一概率。再如，如果Grant-based传输资源的负载较重，网络设备可以配置较大的第一概率，以使部分业务转移到Grant-free传输资源上来，从而减轻Grant-based传输资源的负载；如果Grant-based传输资源的负载较轻，网络设备可配置较小的第一概率。当然，网络设备也可综合考虑Grant-free传输资源和Grant-based传输资源的负载来确定第一概率的取值。
接入控制信息所指示的第一概率(包括第一概率集)可以是以每个小区为单位的，即同一小区的所有终端设备使用相同的第一概率配置。这种情况下，接入控制信息可通过广播消息或多播消息来承载第一概率，例如承载在系统消息(MIB或SIB)、广播或多播RRC信令、广播或多播MAC CE或广播或多播物理层信令(例如，group common DCI)中；当然，网络设备也可以使用单播的终端设备消息来承载接入控制信息以通知每个终端设备该第一概率，例如通过DCI、Paging消息、单播RRC信令或单播MAC CE等承载。
接入控制信息所指示的第一概率也可以是只适用于每个终端设备的，即网络设备可以为同一小区不同的终端设备配置不同的第一概率。这种情况下，网络设备可以使用单播的终端设备消息来承载接入控制信息以通知每个终端设备该第一概率，例如通过DCI、Paging消息、单播RRC信令或单播MAC CE等承载。
需要说明的是，本实施例可以与指示采用Grant-free传输方式的第一终端设备，和/或，用于指示采用Grant-based传输方式的第二终端设备的方案相结合，即网络设备为终端设备配置的接入控制信息中可同时包括下述两个指示：
第一指示：指示采用Grant-free传输方式的第一终端设备，和/或，用于指示采用Grant-based传输方式的第二终端设备。仅当终端设备属于第一终端设备时，才可以使用Grant-free传输方式。或者，仅当终端设备不属于该第二终端设备时，才可以使用Grant-free传输方式。
第二指示：指示第一概率α，第一概率信息用于指示终端设备采用Grant-free传输方式的概率或采用Grant-based传输方式的概率。对于根据第一指示判断允许使用Grant-free传输方式的终端设备来说，如果α表示终端设备采用Grant-free传输方式的概率，则以概率α选择以Grant-free传输方式，以概率1-α选择以Grant-based传输方式；如果α表示终端设备采用Grant-based传输方式的概率，则以概率1-α选择以Grant-free传输方式，以概率α选择以Grant-based传输方式。换句话说，该第一概率仅对允许使用Grant-free传输方式的终端设备(即第一终端设备)有效，不允许使用Grant-free传输方式的终端设备(即第二终端设备)忽略此第一概率。
换而言之，终端设备首先根据第一指示判断自己是否属于第一终端设备，如果是，则进一步根据第二指示所指示的第一概率确定当前传输使用Grant-free传输方式还是Grant-based传输方式。
可选地，接入控制信息可以用于指示特定业务流或特定业务类型使用Grant-free传输方式的概率，其中一种业务类型可以包括多个业务流。具体而言，接入控制信息可以包括第二概率信息，第二概率信息用于指示终端设备传输目标业务的数据时采用Grant-free传输方式的概率或采用Grant-based传输方式的概率。这里，称第二概率信息指示的信息为第二概率。该目标业务可以是一个业务流，也可以是包括至少一个业务流的一种业务类型。在Grant-free传输资源有限而要传输的业务量又比较大的情况下，不同业务类型的数据可以区别对待。例如，URLLC业务对时延要求更高，而mMTC业务往往对时延不敏感，因此，上述情况下，URLLC业务的数据可以具有更高概率使用Grant-free传输方式。或者，网络设备可以指定某一目标业务(例如某一业务流ID)的数据采用Grant-free传输方式的概率或采用Grant-based传输方式的概率。本实施例确定采用Grant-free传输方式的粒度精确到业务，对Grant-free传输资源的使用更灵活，效率更高。
对于小区中具备Grant-free传输能力的终端设备，网络设备可指示每个终端设备传输目标业务(或特定业务类型)的数据时采用Grant-free方式传输的概率。终端设备在每次传输数据时，根据要传输的业务流ID(或业务类型)以及网络设备所指示的采用Grant-free方式传输的概率确定本次传输是否采用Grant-free传输方式。终端设备下次传输时，重新根据待传输的数据的业务流ID(或业务类型)以及网络设备所指示的采用Grant-free方式传输的概率确定是否采用Grant-free传输方式，即终端设备两次传输数据是否采用Grant-free传输方式的判决是不相关的。
网络设备配置给终端设备的接入控制信息可以是第二概率(记为β)，第二概率用于指示终端设备传输目标业务(目标业务类型)的数据时采用Grant-free传输方式的概率。当存在多个业务(多种业务类型)的数据时，网络设备可以为不同业务(或不同业务类型)的数据配置不同的第二概率。下面以不同业务类型的数据配置不同的第二概率为例进行说明。根据可能使用Grant-free传输方式的业务类型数量，网络设备配置给终端设备的接入控制信息可以包括多个第二概率，每个第二概率对应一种业务类型。网络设备配置第一业务类型(例如URLLC业务)对应的第二概率为β1，并配置第二业务类型(例如mMTC业务)对应的第二概率为β2。此时，接入控制信息包括一组第二概率，可称为第二概率集(例如{β1，β2})。当终端设备传输第一业务类型的数据时，以概率β1选择使用Grant-free传输方式，以概率1-β1选择使用Grant-based传输方式；当终端设备传输第二业务类型的数据时，以概率β2选择使用Grant-free方传输式，以概率1-β2选择使用Grant-based传输方式。具体实现上，终端设备可以在每次传输时(假设传输第一业务类型的数据，第二业务类型的数据不再赘述)，从(0,1)范围内随机取一个值(记为λ)，当λ<β1时，终端设备使用Grant-free传输方式；当λ>β1时，终端设备使用Grant-based传输方式。每个第二概率可以用若干比特来指示。表2是某种业务类型对应的第二概率的一个例子，接入控制信息采用3bits表示，表2给出了第二概率的比特表示与实际概率值之间的对应关系。应理解，第二概率也可以以更粗的粒度来划分，则需要更少的比特来表示，或者第二概率也可以以更细的粒度来划分，则需要更多的比特来表示，本申请实施例对此不作限定。

网络设备配置给终端设备的接入控制信息中的第二概率(记为β)，可以用于指示终端设备传输目标业务(目标业务类型)的数据时不采用Grant-free传输方式的概率，即指示传输目标业务(目标业务类型)的数据时终端设备采用Grant-based传输方式的概率。换句话说，终端设备每次传输该目标业务(目标业务类型)的数据时，以概率β选择使用Grant-based传输方式，以概率1-β选择使用Grant-free传输方式。同理，以不同业务类型的数据配置不同的第二概率为例进行说明。根据可能使用Grant-free传输方式的业务类型数量，网络设备配置给终端设备的接入控制信息可以包括多个第二概率，每个第二概率对应一种业务类型，此时，接入控制信息包括一组第二概率，可称为第二概率集。
在只有Grant-based传输方式和Grant-free传输方式两种传输方式的情况下，上述两种指示方式实际上是等效的。
网络设备为终端设备配置的第二概率的取值由网络设备决定，是网络设备的内部实现。例如，在第二概率用于指示终端设备采用Grant-free传输方式的概率的情况下，如果当前Grant-free传输资源碰撞比较严重，网络设备可配置较小的第二概率；如果当前Grant-free传输资源的空置率较高，则网络设备可配置较大的第二概率。再如，如果Grant-based传输资源的负载较重，网络设备可以配置较大的第二概率，以使部分业务转移到Grant-free传输资源上来，从而减轻Grant-based传输资源的负载；如果Grant-based传输资源的负载较轻，网络设备可配置较小的第二概率。当然，网络设备也可综合考虑Grant-free传输资源和Grant-based传输资源的负载来确定第二概率的取值。
接入控制信息所指示的第二概率(包括第二概率集)可以是以每个小区为单位的，即同一小区的所有终端设备使用相同的第二概率配置。这种情况下，接入控制信息可通过广播消息或多播消息来承载第二概率，例如承载在系统消息(MIB或SIB)、广播或多播RRC信令、广播或多播MAC CE或广播或多播物理层信令(例如，group common DCI)中；当然，网络设备也可以使用单播的终端设备消息来承载接入控制信息以通知每个终端设备该第二概率，例如通过DCI、Paging消息、单播RRC信令或单播MAC CE等承载。
接入控制信息所指示的第二概率(包括第二概率集)也可以是只适用于每个终端设备的，即网络设备可以为同一小区不同的终端设备配置不同的第二概率。这种情况下，网络设备可以使用单播的终端设备消息来承载接入控制信息以通知每个终端设备该第二概率，例如通过DCI、Paging消息、单播RRC信令或单播MAC CE等承载。
需要说明的是，本实施例可以与指示采用Grant-free传输方式的第一终端设备，和/或，用于指示采用Grant-based传输方式的第二终端设备的方案相结合，即网络设备为终端设备配置的接入控制信息中可同时包括下述两个指示：
第一指示：指示采用Grant-free传输方式的第一终端设备，和/或，用于指示采用Grant-based传输方式的第二终端设备。仅当终端设备属于第一终端设备时，才可以使用Grant-free传输方式。或者，仅当终端设备不属于该第二终端设备时，才可以使用Grant-free传输方式。
第二指示：指示第二概率(包括第二概率集)。该第二概率用于指示终端设备传输目标业务的数据时采用Grant-free传输方式的概率或采用Grant-based传输方式的概率。该第二概率仅对允许使用Grant-free传输方式的终端设备(即第一终端设备)有效，不允许使用Grant-free传输方式的终端设备(即第二终端设备)忽略此第二概率。
换而言之，终端设备首先根据第一指示判断自己是否属于第一终端设备，如果是，则进一步根据第二指示所指示的第二概率以及本次传输的数据所属的业务(或业务类型)确定当前传输使用Grant-free传输方式还是Grant-based传输方式。
