相关申请的交叉引用
本申请主张在2018年12月21日在中国提交的中国专利申请号No.201811570008.6的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种非授权频段信息传输方法、终端及网络设备。
背景技术
在移动通信系统中，非授权频段(unlicensed band)可以作为授权频段(licensed band)的补充帮助运营商对服务进行扩容。为了与新空口(New Radio，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。非授权频段的大带宽(80或者100MHz)能够减小网络设备和终端的实施复杂度。由于非授权频段由多种技术(Radio Access Technology，RATs)共用，例如无线保真(wireless fidelity，WiFi)、雷达、长期演进型授权辅助接入(Long Term Evolution-Licensed Assisted Access，LTE-LAA)等，因此非授权频段在使用时必须符合预设规则(regulation)以保证所有设备可以公平的使用该资源，该预设规则包括：先听后说(Listen Before Talk，LBT)、最大信道占用时间(Maximum Channel Occupancy Time，MCOT)等规则。当传输节点需要发送信息时，需要先做LBT时，对周围的节点进行功率检测(Energy Detection，ED)，当检测到的功率低于一个门限时，认为信道为空(idle)，传输节点可以进行发送。反之，则认为信道为忙，传输节点不能进行发送。这里所说的传输节点可以是网络设备(如基站)、终端、WiFi接入点(Access Point，AP)等等。传输节点开始传输后，信道占用时间(Channel Occupancy Time，COT)不能超过MCOT。
其中，常用的LBT或者信道接入(channel access)的类型(category，Cat)可以分为Cat 1、Cat 2和Cat 4。Cat 1的LBT或者信道接入机制是发送 节点不做LBT，即no LBT或者立即传输(immediate transmission)。Cat 2的LBT是一次性侦听(one-shot LBT)，即节点在传输前做一次LBT，若信道为空则进行传输，若信道为忙则不传输。Cat 4的LBT是基于回退(back-off)的信道侦听机制，当传输节点侦听到信道为忙时，进行回退继续做侦听，直到侦听到信道为空。对于网络设备，Cat 2的LBT应用于发现信号(Discovery Signal，DS)未携带物理下行共享信道(Physical Downlink Shared Channel，PDSCH)、Cat 4的LBT应用于PDSCH/物理下行控制信道(Physical Downlink Control Channel，PDCCH)/增强PDCCH(enhanced PDCCH，ePDCCH)。而对于终端，Cat 4的LBT对应于类型1(type1)的上行信道接入流程(UL channel access procedure)，Cat 2的LBT对应于类型2(type2)的UL channel access procedure。
例如在非授权频段上，在网络设备发起的信道占用时间(initiated COT)内，即网络设备做LBT得到COT，当下行传输的结尾和上行传输的开始之间的间隔(gap)小于16us的时候，终端可以做Category 1的LBT，当终端的两个连续传输在COT内的gap比25us小的时候，或者上行传输(UL transmission)后面没有下行传输(DL transmission)的时候，可以用Cat 2的LBT。其中终端的两个连续传输可以是基于调度的(scheduled)或者非调度的(granted)。此外，在网络设备initiated COT内，若一个下行突发(burst)跟随在一个上行burst之后，如果调度的上行传输的结尾和上行burst开始之间的gap小于16us，则可以采用Cat 1的LBT，如果gap大于16us但是小于25us，则可以采用Cat 2的LBT。
在增强型授权辅助接入(enhanced Licensed Assisted Access，eLAA)中，网络设备在下行控制信息(Downlink Control Information，DCI)中用1bit指示信道接入类型(Channel Access type)，即type1或者type2 UL channel access procedure。在NR中，网络设备会在DCI中时域资源分配(Time domain resource assignment)域指示调度的起始位置和持续时间(duration)。起始位置和duration决定了传输的结束位置。
在非授权频段上，LBT的时域颗粒度是微秒us级，例如上述能够采用Cat 1的LBT的gap最大为16us。网络设备的调度颗粒度为1个时域符号 (OFDM symbol，OS)，并且所有信号的最小颗粒度是1个OS，因此相关技术的方案无法匹配LBT的颗粒度。例如，当LBT为Cat 2时，终端做one-shot的LBT，然后开始传输。对于15kHz和30kHz子载波间隔，一个OS的duration>25us。对于其他子载波间隔情况也类似，对应于2OS>25us，或者多个OS。因为OS的大小和25us或者16us不是倍数关系，无法保证两个传输之间的gap/LBT的结束时间和下一个传输的起始位置一致。

请参见图1，图1示出本公开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)、个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备等终端侧设备，需要说明的是，在本公开实施例中并不限定终端11的具体类型。网络设备12可以是基站或核心网，其中，上述基站可以是5G及以后版本的基站(例如：gNB、5G NR NB等)，或者其他通信系统中的基站(例如：eNB、无线局域网(wireless local area network，WLAN)接入点、或其他接入点等)，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，在本公开实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。
基站可在基站控制器的控制下与终端11通信，在各种示例中，基站控制器可以是核心网或某些基站的一部分。一些基站可通过回程与核心网进行控制信息或用户数据的通信。在一些示例中，这些基站中的一些可以通过回程链路直接或间接地彼此通信，回程链路可以是有线或无线通信链路。无线通信系统可支持多个载波(不同频率的波形信号)上的操作。多载波发射机能同时在这多个载波上传送经调制信号。例如，每条通信链路可以是根据各种无线电技术来调制的多载波信号。每个已调信号可在不同的载波上发送并且可携带控制信息(例如，参考信号、控制信道等)、开销信息、数据等。
基站可经由一个或多个接入点天线与终端11进行无线通信。每个基站可 以为各自相应的覆盖区域提供通信覆盖。接入点的覆盖区域可被划分成仅构成该覆盖区域的一部分的扇区。无线通信系统可包括不同类型的基站(例如宏基站、微基站、或微微基站)。基站也可利用不同的无线电技术，诸如蜂窝或WLAN无线电接入技术。基站可以与相同或不同的接入网或运营商部署相关联。不同基站的覆盖区域(包括相同或不同类型的基站的覆盖区域、利用相同或不同无线电技术的覆盖区域、或属于相同或不同接入网的覆盖区域)可以交叠。
无线通信系统中的通信链路可包括用于承载上行链路(Uplink，UL)传输(例如，从终端11到网络设备12)的上行链路，或用于承载下行链路(Downlink，DL)传输(例如，从网络设备12到终端11)的下行链路。UL传输还可被称为反向链路传输，而DL传输还可被称为前向链路传输。下行链路传输可以使用授权频段、非授权频段或这两者来进行。类似地，上行链路传输可以使用有授权频段、非授权频段或这两者来进行。
本公开实施例提供了一种非授权频段信息传输方法，应用于终端，如图2所示，该方法包括以下步骤：
步骤21：接收指示信息。
其中，指示信息用于指示传输的实际起始位置，该指示信息可通过一个指示域直接指示传输的实际起始位置，也可以通过多个指示域间接指示传输的实际起始位置。例如通过指示信道接入类型(或称为LBT的category)、实际起始位置是否在某个时域符号(如OFDM Symbol，简称OS)的边缘等联合指示传输的实际起始位置。
其中，指示信息可承载于下行控制信息(Downlink Control Information，DCI)中，或者，指示信息还可以承载于无线资源控制(Radio Resource Control，RRC)中。
步骤22：根据指示信息，从实际起始位置开始传输，其中，实际起始位置位于参考时域符号的起始位置，或实际起始位置位于参考时域符号的内部。
其中，这里所说实际起始位置指的是传输(transmission)或称为传输突发(transmission burst)的实际起始位置，上述传输是终端的上行(Uplink，UL)传输，该传输之前的传输可以是UL传输，也可以是网络设备的下行 (Downlink，DL)传输burst。两个传输之间的间隔可以用来做接收/发送(receive/transmit，Rx/Tx)转换、或Rx/Tx转换加LBT。传输的实际起始位置的确定还可以是两个上行传输中后一个上行传输起始位置的确定。本公开实施例中参考时域符号可以指任一时域符号，也就是说，传输的实际起始位置可以位于某个时域符号的起始位置(或称为边缘、起始边缘)，也可以位于时域符号的内部，这里所说的内部指的是除起始位置之外的其他位置。这样传输的起始位置更加灵活，可解决传输调度和非授权频段传输的颗粒度匹配问题，保证非授权频段下可进行正常的上行传输。
下面本公开实施例将进一步结合附图对指示信息以及终端如何得到传输的实际起始位置作出说明。其中，以指示信息通过多个指示域联合指示为例，指示信息的指示方式包括但不限于：
方式一、指示信息包括用于指示信道接入类型的第一指示域，以及用于指示实际起始位置是否为时域资源分配的起始位置的第二指示域。
其中，信道接入类型包括但不限于：LBT的category1、category2和category4等，其中，若终端采用LBT的category1，则无需进行LBT；若终端采用LBT的category2，则在传输前需要进行一次LBT；若终端采用LBT的category4，则在传输前需要持续LBT直到侦听到信道为空。本公开实施例中时域资源分配(如DCI中“Time domain resource assignment”域中调度的资源)的颗粒度为时域符号，两次传输之间的间隔(gap)小于16us时，可采用LBT的category1；两次传输之间的间隔小于25us时，可采用LBT的category2。也就是说，若终端采用LBT的category1，则两次传输之间的gap要小于16us；若终端采用LBT的category2，则LBT的时间需要25us。而不同子载波间隔(Sub-Carrier Spacing，SCS)对应的时域符号的时间长度不同，可能会出现时域资源分配的颗粒度与gap/LBT的颗粒度不匹配的问题。为了避免该问题，本公开实施例的网络设备可通过指示信息指示传输的实际起始位置位于时域符号边缘或内部来进行颗粒度匹配。
终端根据第一指示域可得到采用的信道接入类型，如上所述不同信道接入类型对应不同的gap或LBT的时间，即第一指示域还可隐式指示实际起始位置与时域符号之间的偏移，根据第二指示域得知实际起始位置是否为时域 资源分配的起始位置。以指示信息承载于DCI中为例，假设网络设备在DCI中使用2bits的第一指示域来指示LBT的category，包括LBT的category1、2和4；在DCI中使用1bit的第二指示域来指示传输是否从某个时域符号(如时域资源分配所指示的第一个时域符号)的起始位置或边缘(boundary)开始。例如，第二指示域的1bit的值为1时，表示实际起始位置是DCI中“Time domain resource assignment”域指示调度的起始位置。第二指示域的1bit的值为0时，表示实际起始位置不在DCI中“Time domain resource assignment”域指示调度的起始位置，可位于指示的起始位置所在时域符号内或者所在时域符号前后的时域符号内。或者说，第二指示域指示了gap/LBT是从一个时域符号的起始位置开始，还是gap/LBT从一个时域符号的中间位置开始，结束于该时域符号的结束位置。其中，前者对应于在OS内开始传输，后者对应于从OS的起始边缘开始传输。
具体地，在该方式下包括以下场景：
场景一、实际起始位置不为时域资源分配的起始位置的情况
具体地，步骤22包括：在第二指示域指示实际起始位置不为时域资源分配的起始位置的情况下，若第一指示域指示信道接入类型为第一信道接入类型，则从与参考时域符号的起始位置偏移第一偏移的实际起始位置开始传输。或者，步骤22包括：在第二指示域指示实际起始位置不为时域资源分配的起始位置的情况下，若第一指示域指示信道接入类型为第二信道接入类型，则从与参考时域符号的起始位置偏移第二偏移的实际起始位置开始传输。其中，第一信道接入类型不同于第二信道类型，第一偏移不同于第二偏移。其中，第一偏移为16us和25us中的一项，第二偏移为16us和25us中的另一项。
该场景为传输从某个时域符号内部开始的场景，当第一指示域指示LBT的category1时，传输的实际起始位置与参考时域符号的起始位置之间间隔16us；当第一指示域指示LBT的category2时，传输的实际起始位置与参考时域符号的起始位置之间间隔25us；当第一指示域指示LBT的category4时，忽略第二指示域。
值得指出的是，若第一指示域指示的信道接入类型为特定信道接入类型时，第二指示域指示的内容失效，特定信道接入类型为LBT的category4。
进一步地，在该场景下，参考时域符号包括：时域资源分配的第一个时域符号，或时域资源分配的起始位置之前的第M个时域符号，或时域资源分配的起始位置之后的第N个时域符号，M、N为大于或等于1的整数。也就是说实际起始位置所在的时域符号可以是时域资源分配的第一个时域符号，也可以是时域资源分配的起始位置之前或之后的时域符号。
以参考时域符号为时域资源分配的起始位置之前的第M个时域符号为例，当传输的实际起始位置在某个时域符号内开始时，对于上行传输，网络设备给终端指示信道接入类型(LBT的category)以及时域传输的实际起始位置。对于终端采用LBT的category1的信道接入类型时，隐式地指示了UL传输之前有一个gap不大于16us；对于终端采用LBT的category2的信道接入类型时，隐式地指示了UL传输之前需要做25us的LBT。如图3所示，UL传输在DL传输之后，在DL传输结束位置和指示的UL传输开始位置之间预留一个时域符号作为Tx/Rx转换或者Tx/Rx转换和LBT。为了使得两个传输之间的gap不大于16us或者25us，UL传输的实际起始位置要在时域资源分配(指示的时域资源)的起始位置之前的时域符号内，当第一指示域指示的信道接入类型为LBT的category1时，UL传输的实际起始位置为：时域资源分配(即指示的时域资源)的起始位置-1OS+16us处。当第一指示域指示的信道接入类型为LBT的category2时，UL传输的实际起始位置为：时域资源分配的起始位置-1OS+25us。
值得指出的是，对于SCS大于30kHz的情况，上述计算实际起始位置时减掉的时域符号个数(即M的值)，取决于留作Tx/Rx转换和LBT的时域符号个数，该值可能会大于1。其中，M的值可以在RRC中指示，也可以在DCI中指示，或者预定义(如协议直接约定)。
以参考时域符号为时域资源分配的第一个时域符号为例，当传输的实际起始位置在某个时域符号内开始时，对于上行传输，网络设备给终端指示信道接入类型以及时域传输的实际起始位置，对于终端采用LBT的category1的信道接入类型时，隐式地指示了UL传输之前有一个gap不大于16us；对于终端采用LBT的category2的信道接入类型时，隐式地指示了UL传输之前需要做25us的LBT。如图4所示，UL传输在DL传输之后，在DL传输 结束位置和指示的UL传输开始位置之间预留一个时域符号作为Tx/Rx转换或者Tx/Rx转换和LBT。为了使得两个传输之间的间隔不大于16us或者25us，UL传输的实际起始位置要在指示的第一个时域符号内，当第一指示域指示的信道接入类型为LBT的category1时，UL传输的实际起始位置为：时域资源分配(即指示时域资源)的起始位置+16us处。当第一指示域指示的信道接入类型为LBT的category2时，UL传输的实际起始位置为：时域资源分配的起始位置+25us处。
值得指出的是，对于SCS大于30kHz的情况，上述计算实际起始位置时还可顺延多个时域符号，即参考时域符号为时域资源分配的起始位置之后的第N个时域符号，实际起始位置为：时域资源分配的起始位置+N*OS+25us。其中，顺延的时域符号个数(即N的值)，取决于留作Tx/Rx转换和LBT的时域符号个数，该值可能会大于1。其中，N的值可以在RRC中指示，也可以在DCI中指示，或者预定义(如协议直接约定)。
进一步地，考虑到网络设备和终端间的传输时延的影响，实际起始位置可能需要延后一个定时提前(Timing Advance，TA)，因此在指示信息中可以额外增加一个bit的第三指示域，来指示传输是否需要延后一个TA。具体地，指示信息包括：用于指示实际起始位置是否偏移定时提前TA的第三指示域。例如第三指示域的1bit的值为1表示传输延后TA，第三指示域的1bit的值0表示不需要额外延后TA，或者反之。
以终端采用LBT的category2进行信道接入为例，对于实际起始位置在时域资源分配的起始位置之前的第M个时域符号内部的场景，当该bit的值为1时，实际起始位置为：时域资源分配的起始位置-M*OS+25us+TA。对于实际起始位置在时域资源分配的第一个时域符号内部的场景，当该bit的值为1时，实际起始位置为：时域资源分配的起始位置+25us+TA。对于实际起始位置在时域资源分配的起始位置之后的第N个时域符号内开始的场景，当该bit的值为1时，实际起始位置为：时域资源分配的起始位置+N*OS+25us+TA。
场景二、在实际起始位置为时域资源分配的起始位置的情况
步骤22包括：在第二指示域指示实际起始位置为时域资源分配的起始位置的情况下，从时域资源分配的起始位置开始传输。
如图5所示，UL传输在DL传输之后，在DL传输结束位置和指示的UL传输开始位置之间预留一个时域符号作为Tx/Rx转换或者Tx/Rx转换和LBT。在指示信息指示UL传输的实际起始位置在时域资源分配(指示的时域资源)的起始位置时，从指示的时域资源处开始传输。
该场景为传输从某个时域符号的起始位置开始的场景，传输从时域资源分配的起始位置开始。当第一指示域指示的信道接入类型为特定信道接入类型时，第二指示域指示的内容失效，特定信道接入类型为LBT的category4。
方式二、指示信息包括：用于指示信道接入类型是否为特定信道接入类型的第四指示域；用于指示实际起始位置是否为时域资源分配的起始位置的第五指示域；以及用于指示实际起始位置与参考时域符号的起始位置之间的偏移的第六指示域。
其中，偏移包括：16us、25us或25us+TA。特定信道接入类型可以为LBT的category4，其中，终端采用LBT的category4时，在传输前需要持续LBT直到侦听到信道为空。终端根据第四指示域可得知采用的信道接入类型是否为LBT的category4。以指示信息承载于DCI中为例，假设网络设备在DCI中使用1bit的第四指示域来指示信道接入类型是否为LBT的category4，例如第四指示域的1bit的值为1时，表示信道接入类型为LBT的category4，第四指示域的1bit的值为0时，表示信道接入类型不为LBT的category4，即为LBT的category1或LBT的category2。
进一步地，网络设备还可以在DCI中使用1bit的第五指示域来指示传输是否从某个时域符号(如时域资源分配所指示的第一个时域符号)的起始位置或边缘(boundary)开始，例如第五指示域的1bit的值为1时，表示实际起始位置是DCI中“Time domain resource assignment”域指示调度的起始位置。第五指示域的1bit的值为0时，表示实际起始位置不在DCI中“Time domain resource assignment”域指示调度的起始位置，可位于指示的起始位置所在时域符号内或者所在时域符号前后的时域符号内。或者说，第五指示域指示了gap/LBT是从一个时域符号的起始位置开始，还是gap/LBT从一个时域符号的中间位置开始，结束于该时域符号的结束位置。其中，前者对应于在OS内开始传输，后者对应于从OS的起始边缘开始传输。
进一步地，网络设备还可以在DCI中使用2bits或1bit的第六指示域来指示传输的实际起始位置与参考时域符号的起始位置之间的偏移，以指示传输的实际起始位置。其中，参考时域符号包括：时域资源分配的第一个时域符号，或时域资源分配的起始位置之前的第M个时域符号，或时域资源分配的起始位置之后的第N个时域符号，M、N为大于或等于1的整数。
以参考时域符号为时域资源分配的第一个时域符号为例，例如第六指示域的2bits的值为00时，表示实际起始位置为：参考时域符号的起始+16us；例如第六指示域的2bits的值为01时，表示实际起始位置为：参考时域符号的起始+25us；例如第六指示域的2bits的值为10时，表示实际起始位置为：参考时域符号的起始+25us+TA；例如第六指示域的2bits的值为11时，表示为无效bit。
值得指出的是，在不考虑传输时延影响的情况下，实际传输位置中的TA可以考虑不计，第六指示域可采用1bit指示实际起始位置，例如第六指示域的1bit的值为0时，表示实际起始位置为：参考时域符号的起始+16us；例如第六指示域的1bit的值为1时，表示实际起始位置为：参考时域符号的起始+25us。
如上述方式一所述，两次传输之间的间隔小于16us时，可采用LBT的category1；两次传输之间的间隔小于25us时，可采用LBT的category2。也就是说，若终端采用LBT的category1，则两次传输之间至少需要16us的gap；若终端采用LBT的category2，则两次传输之间至少需要25us。那么在第六指示域指示实际起始位置与参考时域符号的起始位置之间的偏移时，第六指示域还隐式指示了终端所采用的信道接入类型。例如，第六指示域的2bits的值为00时，表示实际起始位置为：参考时域符号的起始+16us，并隐式指示了终端采用LBT的category1。第六指示域的2bits的值为01时，表示实际起始位置为：参考时域符号的起始+25us；2bits的值为10时，表示实际起始位置为：参考时域符号的起始+25us+TA，同时这2bits的值为“01”或“10”时还隐式指示了终端采用LBT的category2。
在该方式下，步骤22包括：在第四指示域指示信道接入类型不为特定信道接入类型、且第五指示域指示实际起始位置不为时域资源分配的起始位置 的情况下，根据第六指示域，得到实际起始位置和信道接入类型，并从实际起始位置开始传输。例如第四指示域指示接入类型不为LBT的category4，即值为0；第五指示域指示实际起始位置不为时域资源分配的起始位置，即值为0时，根据第六指示域的2bits得到传输的实际起始位置以及终端的信道接入类型。
或者，步骤22包括：在第四指示域指示信道接入类型不为特定信道接入类型、且第五指示域指示实际起始位置为时域资源分配的起始位置的情况下，根据第六指示域，得到信道接入类型，并从时域资源分配的起始位置开始传输。例如第四指示域指示接入类型不为LBT的category4，即值为0；第五指示域指示实际起始位置为时域资源分配的起始位置，即值为1时，根据第六指示域的2bits得到终端的信道接入类型，并从时域资源分配的起始位置开始传输。
或者，步骤22包括：在第四指示域指示信道接入类型为特定信道接入类型的情况下，忽略第五指示域和第六指示域。例如第四指示域指示接入类型为LBT的category4，即值为1，这时终端忽略第五指示域和第六指示域的解读。
以上介绍了指示信息如何指示传输的实际起始位置的不同实现方式，以及终端对于不同实际起始位置的不同处理方式，下面本公开实施例将进一步介绍终端在得知传输的实际起始位置后的行为。本公开实施例中终端在得知传输的实际起始位置之后，还包括：在参考时域符号中实际起始位置之后的时域资源内，发送预设信息，预设信息包括：占位信号、数据、参考信号和扩展循环前缀(extended Cyclic Prefix，extended CP)中的至少一项。也就是说，终端在传输开始的部分时域符号内，可以传输占位信号、数据、参考信号扩展循环前缀和其他信号中的至少一项，其中，数据可以为物理上行共享信道(Physical Uplink Shared Channel，PUSCH)、参考信号可以为跟踪参考信号(Sounding Reference Signal，SRS)。

以上实施例从终端侧介绍了本公开的非授权频段信息传输方法，下面本实施例将结合附图对网络设备侧的非授权频段信息传输方法做进一步介绍。
如图8所示，本公开实施例的非授权频段信息传输方法，应用于网络设备侧，该方法包括以下步骤：
步骤81：发送指示信息；指示信息用于指示传输的实际起始位置，该实际起始位置位于参考时域符号的起始位置，或实际起始位置位于参考时域符号的内部。
其中，指示信息用于指示传输的实际起始位置，该指示信息可通过一个指示域直接指示传输的实际起始位置，也可以通过多个指示域间接指示传输的实际起始位置。进一步地，指示信息可承载于DCI中，或者，指示信息还可以承载于RRC中。
本公开实施例中参考时域符号可以指任一时域符号(如OFDM符号)，也就是说，传输的实际起始位置可以位于某个时域符号的起始位置，也可以位于时域符号的内部，这里所说的内部指的是除起始位置之外的其他位置。这样传输的起始位置更加灵活，可解决传输调度和非授权频段传输的颗粒度匹配问题，保证非授权频段下可进行正常的上行传输。
其中，以指示信息通过多个指示域联合指示为例，指示信息的指示方式包括但不限于：
方式三、用于指示信道接入类型的第一指示域；以及用于指示实际起始位置是否为时域资源分配的起始位置的第二指示域。
其中，信道接入类型包括但不限于：LBT的category1、category2和category4等，以指示信息承载于DCI中为例，假设网络设备在DCI中使用2bits的第一指示域来指示LBT的category，包括LBT的category1、2和4。其中，这些信道接入类型的接入形式可参照终端侧实施例的方式一中的介绍，故在此不再赘述。
其中，信道接入类型包括第一信道接入类型和/或第二信道接入类型，其中，第一信道接入类型隐式指示实际起始位置与参考时域符号的起始位置之间间隔第一偏移，第二信道接入类型隐式指示实际起始位置与参考时域符号的起始位置之间间隔第二偏移。其中，第一信道接入类型不同于第二信道类 型，第一偏移不同于第二偏移。其中，第一偏移为16us和25us中的一项，第二偏移为16us和25us中的另一项。也就是说，不同信道接入类型对应不同的间隔，即第一指示域还可隐式指示实际起始位置与时域符号之间的间隔偏移(或称为偏移)。例如两次传输之间的间隔(gap)小于16us时，可采用LBT的category1；两次传输之间的间隔小于25us时，可采用LBT的category2。也就是说，若终端采用LBT的category1，则两次传输之间的间隔小于16us；若终端采用LBT的category2，则需要25us的LBT。
进一步地，考虑到网络设备和终端间的传输时延的影响，实际起始位置可能需要延后一个定时提前TA，因此在指示信息中可以额外增加一个bit的第三指示域，来指示传输是否需要延后一个TA。具体地，指示信息还包括：用于指示实际起始位置是否偏移定时提前TA的第三指示域。例如第三指示域的1bit的值为1表示传输延后TA，第三指示域的1bit的值0表示不需要额外延后TA，或者反之。以终端采用LBT的category2进行信道接入为例，对于实际起始位置在时域资源分配的起始位置之前的时域符号内开始的场景，当该bit的值为1时，实际起始位置为：时域资源分配的起始位置-M*OS+25us+TA。对于实际起始位置在时域资源分配的起始位置之后的时域符号内开始的场景，当该bit的值为1时，实际起始位置为：时域资源分配的起始位置+25us+TA，或时域资源分配的起始位置+N*OS+25us+TA。
方式四、指示信息包括：用于指示信道接入类型是否为特定信道接入类型的第四指示域；用于指示实际起始位置是否为时域资源分配的起始位置的第五指示域；以及用于指示实际起始位置与参考时域符号的起始位置之间的偏移的第六指示域。
其中，偏移包括：16us、25us或25us+TA。特定信道接入类型可以为LBT的category4，其中，终端采用LBT的category4时，在传输前需要持续LBT直到侦听到信道为空。终端根据第四指示域可得知采用的信道接入类型是否为LBT的category4。以指示信息承载于DCI中为例，假设网络设备在DCI中使用1bit的第四指示域来指示信道接入类型是否为LBT的category4，例如第四指示域的1bit的值为1时，表示信道接入类型为LBT的category4，第四指示域的1bit的值为0时，表示信道接入类型不为LBT的category4，即为 LBT的category1或LBT的category2。
其中，参考时域符号包括：时域资源分配的第一个时域符号，或时域资源分配的起始位置之前的第M个时域符号，或时域资源分配的起始位置之后的第N个时域符号，M、N为大于或等于1的整数。进一步地，网络设备还可以在DCI中使用2bits或1bit的第六指示域来指示传输的实际起始位置与参考时域符号的起始位置之间的偏移的第六指示域，以指示传输的实际起始位置。其中，参考时域符号包括：时域资源分配的第一个时域符号，或时域资源分配的起始位置之前的第M个时域符号，或时域资源分配的起始位置之后的第N个时域符号，M、N为大于或等于1的整数。以参考时域符号为时域资源分配的第一个时域符号为例，例如第六指示域的2bits的值为00时，表示实际起始位置为：参考时域符号的起始+16us；例如第六指示域的2bits的值为01时，表示实际起始位置为：参考时域符号的起始+25us；例如第六指示域的2bits的值为10时，表示实际起始位置为：参考时域符号的起始+25us+TA；例如第六指示域的2bits的值为11时，表示为无效bit。值得指出的是，在不考虑传输时延影响的情况下，实际传输位置中的TA可以考虑不计，第六指示域可采用1bit指示实际起始位置，例如第六指示域的1bit的值为0时，表示实际起始位置为：参考时域符号的起始+16us；例如第六指示域的1bit的值为1时，表示实际起始位置为：参考时域符号的起始+25us。
本公开实施例的非授权频段信息传输方法中，网络设备通过指示信息指示终端的上行传输的开始位置可以位于某个时域符号的起始位置，也可以位于某个时域符号的内部，使得传输起始位置更加灵活，可解决信息调度和非授权频段传输的颗粒度匹配问题，进一步保证非授权频段下正常的上行传输。
以上实施例分别详细介绍了不同场景下的非授权频段信息传输方法，下面本实施例将结合附图对其对应的网络设备做进一步介绍。

用于指示信道接入类型是否为特定信道接入类型的第四指示域；

其中，偏移包括：16us、25us或25us+TA。
其中，参考时域符号包括：时域资源分配的第一个时域符号，或时域资源分配的起始位置之前的第M个时域符号，或时域资源分配的起始位置之后的第N个时域符号，M、N为大于或等于1的整数。
值得指出的是，本公开实施例的网络设备通过指示信息指示终端的上行传输的开始位置可以位于某个时域符号的起始位置，也可以位于某个时域符号的内部，使得传输起始位置更加灵活，可解决信息调度和非授权频段传输的颗粒度匹配问题，进一步保证非授权频段下正常的上行传输。
需要说明的是，应理解以上网络设备和终端的各个模块的划分仅仅是一 种逻辑功能的划分，实际实现时可以全部或部分集成到一个物理实体上，也可以物理上分开。且这些模块可以全部以软件通过处理元件调用的形式实现；也可以全部以硬件的形式实现；还可以部分模块通过处理元件调用软件的形式实现，部分模块通过硬件的形式实现。例如，确定模块可以为单独设立的处理元件，也可以集成在上述装置的某一个芯片中实现，此外，也可以以程序代码的形式存储于上述装置的存储器中，由上述装置的某一个处理元件调用并执行以上确定模块的功能。其它模块的实现与之类似。此外这些模块全部或部分可以集成在一起，也可以独立实现。这里所述的处理元件可以是一种集成电路，具有信号的处理能力。在实现过程中，上述方法的各步骤或以上各个模块可以通过处理器元件中的硬件的集成逻辑电路或者软件形式的指令完成。
