Description

一种通信方法、通信装置和系统 技术领域
本申请涉及无线通信技术领域，特别涉及一种通信方法及通信装置。
背景技术
随着通信技术的发展，业务需求越来越多样化。为了更好的适配不同类型的业务需求，考虑引入一种与现有协议能够支持的终端设备类型不同的终端设备，例如，新无线-轻(new radio-light,NR-light)终端设备。NR-light终端设备具有较低的带宽处理能力，因此占用较少的带宽资源。
如何设计NR-light终端设备通信技术方案，使其与现有协议尽可能兼容，是需要解决的问题。
发明内容
本申请提供一种通信方法、通信装置和系统，使得NR-light终端设备可以低开销地获取到属于自己的系统信息块(system informationblock,SIB)，并且，本申请实施例揭示的技术方案具有良好的前向兼容性。
第一方面，本申请实施例提供的一种通信的方法，包括：
网络设备向第一终端设备发送下行控制信息(downlink control information,DCI)，所述DCI包括：时域资源信息，所述时域资源信息用于确定时域资源，所述时域资源为第一数据信道所在的时域资源；频域资源信息，所述频域资源信息用于确定频域资源，所述频域资源为所述第一数据信道所在的频域资源以及第二数据信道所在的频域资源；所述第二数据信道位于与所述第一数据信道所在的时域资源不同的时域资源；所述第一终端设备在确定的所述时域资源和所述频域资源上，接收来自所述网络设备、位于所述第一数据信道的信号；其中，所述第一数据信道用于所述第一终端设备与所述网络设备进行通信；所述第二数据信道用于第二终端设备与所述网络设备进行通信。
其中以上所指的通信可以为上行通信和/或下行通信。上行通信和/或下行通信的具体介绍，请参见本申请具体实施方式中的相关内容。
在一种可能的设计中，所述时域资源信息包括：时域偏移信息，所述时域偏移信息用于确定所述DCI所在的时间单元与第一时间单元的时域间隔，所述第一时间单元为所述第一数据信道所在的时间单元；时域起始位置信息，所述时域起始位置信息用于确定第一位置，所示第一位置为所述第一数据信道在所述第一时间单元的时域起始位置；持续时间信息，所述持续时间信息用于确定第一时长，所示第一时长为所述第一数据信道在所述第一时间单元占用的时长。
在一种可能的设计中，所述第一位置还为所述第二数据信道在第二时间单元中的时域起始位置，所述第二时间单元为所述第二数据信道所在的时间单元；所述第一时长还为所述第二数据信道在所述第二时间单元中占用的时长。
在一种可能的设计中，所述第一数据信道位于第一带宽部分(bandwidth part，BWP)，所述DCI和所述第二数据信道位于第二BWP。所述DCI还包括BWP信息，所述BWP信 息用于确定所述第一BWP。所述方法还包括：所述第一终端设备在确定的所述第一BWP上，接收来自所述网络设备的位于所述第一数据信道的所述信号。
以上设计中第一数据信道位于与DCI和第二数据信道不同的BWP。由于第一终端设备的第一数据信道位于与第二终端设备的第二数据信道不同的第二BWP，第一终端设备与第二终端设备可以在不同的BWP上完成剩余的初始接入过程和随机接入过程，使得在同一BWP上进行随机接入的终端设备数目减少，进而有效减低同一BWP上随机接入的冲突概率。不仅如此，当第一终端设备切换到与第一BWP不同的第二BWP之后，若网络设备想要寻呼的是在第二BWP上通信的终端设备，那么第一终端设备将不会接收到不必要的寻呼消息，从而使得寻呼更有针对性，降低了整个系统的开销。
在一种可能的设计中，所述BWP信息包括：BWP偏移信息、所述BWP偏移信息和所述第一BWP带宽信息、或者所述第一BWP起始位置信息和所述第一BWP带宽信息；
其中，所述BWP偏移信息用于确定所述第二BWP与所述第一BWP之间的频域间隔；所述第一BWP带宽信息用确定所述第一BWP占用的带宽；所述第一BWP起始位置信息用于确定所述第一BWP的频域起始位置。

在一种可能的设计中，若所述时域资源信息对应0个比特，则所述时域资源是预定义的。该设计可以最大限度的节省系统开销。
在一种可能的设计中，所述第一终端设备与所述第二终端设备为不同类型的终端设备。例如，第一终端设备为NR-light终端设备，第二终端为普通终端设备。
在一种可能的设计中，所述第一数据信道上的信号包括系统消息。所述第一数据信道可以为承载系统消息的物理下行共享信道(physical downlink shared channel,PDSCH)。
在一种可能的设计中，所述DCI还包括确认信息，所述确认信息用于确定所述第二数据信道位于与所述第一数据信道所在的时域资源不同的时域资源。该设计直接明确，无需第一终端设备做大量的信息处理和判断。
在一种可能的设计中，以下至少一项位于所述DCI的保留域中：所述时域偏移信息、所述时域起始位置信息、所述持续时间信息、所述BWP信息和所述确认信息。如此体现了良好的前向兼容性。
以上技术方案，通过至少复用普通终端设备的一部分信息，使得NR-light终端设备能够低开销地获取属于自己的SIB，并且该方法具有良好的前向兼容性。
第二方面，本申请的实施例提供了一种通信方法，包括：
网络设备在第二BWP上向第一终端设备发送DCI，所述DCI包括BWP信息，所述BWP信息用于确定第一BWP，第一数据信道位于第一BWP。第一终端设备在确定的第一BWP上，接收来自所述网络设备、位于第一数据信道的信号。
在一种可能的设计中，所述BWP信息包括：BWP偏移信息、所述BWP偏移信息和所述第一BWP带宽信息、或者所述第一BWP起始位置信息和所述第一BWP带宽信息。
其中，所述BWP偏移信息用于确定所述第二BWP与所述第一BWP之间的频域间隔；所述第一BWP带宽信息用确定所述第一BWP占用的带宽；所述第一BWP起始位置信息用于确定所述第一BWP的频域起始位置。
该设计体现了BWP信息配置的灵活性。
第一终端设备还需要在确定第一数据信道在第一BWP上的具体的时域资源和频域资 源。
在一种可能的设计中，该具体的时域资源和频域资源的确定方式即为第一方面中确定第一数据信道的时域资源和频域资源的方式。
在一种可能的设计中，第一终端设备可以复用DCI中现有的频域资源分配和时域资源分配字段的信息，也即将与DCI在同一BWP，第二BWP，的第二数据信道的时频资源确定为第一数据信道在第一BWP的时频资源。所述第二数据信道用于网络设备与第二终端设备进行通信。
可选的，第一终端设备与第二终端设备为不同类型的终端设备。例如，第一终端设备为NR-light终端设备，第二终端为普通终端设备。
在该设计中，关于第一数据信道的频域资源的确定，可以有如下几种情况：
若第一BWP占用带宽大于第二BWP的带宽，第一终端设备使用与确定第二数据信道在第二BWP中的频域资源相同的方式，确定第一数据信道在第一BWP中频域资源；
若第一BWP占用带宽小于第二BWP的带宽，且频域分配字段确定的频域资源长度大于第一BWP占用的带宽，则第一终端设备确定第一数据信道的频域资源为第一BWP的带宽。
若第一BWP占用带宽小于第二BWP的带宽，且频域分配字段确定的频域资源长度小于等于第一BWP占用的带宽、频域分配字段确定的频域资源部分超出第一BWP的带宽，则第一终端设备频域分配字段确定的频域资源起始位置为第一BWP的起始位置，频域资源长度为频域分配字段所确定的长度。

以上技术方案，不仅实现由同一DCI指示两种不同类型的终端设备的数据信道，保证了前向的兼容性。进一步地，由于第一终端设备的第一数据信道位于与第二终端设备的第二数据信道不同的第二BWP，也就是说，第一终端设备与第二终端设备在不同的BWP上完成剩余的初始接入过程和随机接入过程，使得在同一BWP上进行随机接入的终端设备数目减少，进而有效减低同一BWP上随机接入的冲突概率。不仅如此，当第一终端设备切换到与第二BWP不同之后，若网络设备想要寻呼的是在第二BWP上通信的终端设备，那么第一终端设备将不会接收到不必要的寻呼消息，从而使得寻呼更有针对性，降低了整个系统的开销。

如图1所示为本申请实施例适用的一种通信系统架构示意图。如图1所示，终端设备1和终端设备2可以通过网络设备10接入一个或多个无线网络，并通过该网络设备10，与无线网络进行上行通信和/或下行通信。其中所述无线网络包括但不限于：长期演进(long term evolution，LTE)系统、第五代(5th generation，5G)移动通信系统中的NR(new radio)系统，以及其他现有的或未来的移动通信系统等。
现对本申请实施例涉及的部分用语进行解释，以便于理解本申请实施例中揭示的技术方案。
1、终端设备(terminal device)。本申请实施例中的终端设备是一种具有无线收发功能的设备，可以简称为终端(terminal)，又可称为用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)、车载终端设备、远方站、远程终端设备等。终端设备可以是固定的或者移动的。终端设备具体的形态可以是，例如，手机(mobile phone)、蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、可穿戴设备、平板电脑(pad)、台式个人计算机、笔记本电脑、车载终端、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)等。除了常规的语音、视频和数字通信，终端设备还可以应用于如下场景：虚拟现实(virtual reality，VR)、增强现实(augmented reality，AR)、工业控制(industrial control)、无人驾驶(self driving)、远程手术(remote medical surgery)、智能电网(smart grid)、运输安全(transportation safety)、智慧城市(smart city)、智慧家庭(smart home)等。需要说明的是，终端设备支持至少一种无线通信技术，例如LTE、NR、宽带码分多址(wideband code division multiple access，WCDMA)等。
本文前面提到的NR-light终端设备，还可以称为降低能力(reduced capability，REDCAP)终端设备，可以是传感器或者穿戴设备等，其特点可以是：相对与其它终端设备，它们的制造成本较低，并且与网络设备通信的带宽较低、功耗也较低。
2、网络设备(network device)。本申请实施例中的网络设备是一种为终端设备提供无线通信功能的设备，也可称之为无线接入网(radio access network，RAN)设备等。具体地，网络设备包括但不限于：5G移动通信系统中的下一代基站(next generation nodeB，gNB)、LTE系统中的演进型节点B(evolved node B，eNB)、基带单元(baseband unit，BBU)、收发点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)、中继站、接入点等。网络设备还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器、集中单元(centralized unit，CU)、分布单元(distributed unit，DU)等。网络设备支持至少一种无线通信技术，例如LTE、NR、WCDMA等。
3、上行通信。本申请实施例中的上行通信又可以称之为上行传输，指的是在终端设备与网络设备之间的通信中，终端设备向网络设备发送信号的过程。其中，终端设备向网络设备发送的信号可以称为上行信号或上行信息。示例的，上行信号包括上行控制信息(uplink control information，UCI)和上行数据。上行控制信息用于承载终端设备反馈的相关信息，例如信道状态信息(channel state information，CSI)、确认应答(acknowledgement，ACK)或否认应答(negative acknowledge，NACK)等。具体的，上行控制信息可以承载在物理上行控制信道(physical uplink control channel，PUCCH)上，也可以承载在物理上行共享信道(physical uplink shared channel，PUSCH)上；上行数据可以承载在PUSCH上。
4、下行通信。本申请实施例中下行通信又可以称之为下行传输，指的是在终端设备与网络设备之间的通信中，终端设备接收网络设备发送的信号的过程。其中，终端设备接收网络设备发送的信号可以称为下行信号或下行信息。示例的，下行信号可以包括下行控制信息(downlink control information,DCI)和下行数据(downlink data)。下行控制信息是用于下行数据调度的相关信息，例如，数据信道的资源分配、调制编码方式等信息。具体的，DCI可以承载在PDCCH上，下行数据可以承载在物理下行共享信道(physical downlink shared channel，PDSCH)上。
上行数据的通信和/或下行数据的通信也可以被称为通信或者数据通信。
5、载波带宽部分。本申请实施例中的载波带宽部分可以简称为带宽部分(bandwidth part，BWP)，指的是载波上一段连续或非连续的频域资源。其中，这段连续或非连续的频域资源的带宽不超过终端设备的带宽能力，即BWP的带宽小于或等于终端设备支持的最大带宽。以BWP为载波上一段连续的频域资源为例，BWP可以是载波上一组连续的资源块(resource block，RB)，或者BWP是载波上一组连续的子载波，或者BWP是载波上一组连续的资源块组(resource block group，RBG)等。其中，一个RBG中包括一个或多个RB，例如1个、2个、4个、8个或16个等。一个RB可以包括一个或多个子载波，例如12个等。
本申请实施例中终端设备与网络设备通信所使用的BWP，可以是网络设备配置的，也可以是协议预定义的，该协议可以是第三代合作伙伴计划项目(the 3 rd generation partnership project，3GPP)。对于一个终端设备来说，网络设备可以为该终端设备在一个载波内配置一个或多个BWP。例如，如图2(a)所示，网络设备为终端设备在一个载波内配置了一个BWP。其中，BWP的带宽不超过终端设备的带宽能力，且BWP的带宽不大于载波带宽。再例如，如图2(b)所示，网络设备为终端设备在一个载波内配置了两个BWP，分别为BWP1和BWP2，其中，BWP1与BWP2存在重叠。又例如，如图2(c)所示，网络设备为终端设备在一个载波内配置了两个BWP，分别为BWP1和BWP2，其中BWP1和BWP2不重叠。需要说明 的是，本申请实施例中网络设备为终端设备配置的BWP的个数不是无限制的。举例来说，网络设备为终端设备最多可以配置4个BWP。
此外，网络设备可以针对每个BWP，为终端设备配置系统参数。本申请实施例中，不同的BWP对应的系统参数可以相同，也可以不同。
6、时频资源。本申请实施例中的时频资源可以包括频域资源和时域资源，是信号传输的载体。其中，频域资源可以频域单元为单位，例如该频域单元为如上所述的RB。时域资源可以以时间单元为单位。
7、时间单元。本申请实施例中时间单元可以指的是在时域资源上的一段时间。例如，在时域上，终端设备和网络设备之间是以时间单元为基本单位进行通信的。例如，时间单元可以为无线帧(radio frame)、子帧(subframe)、时隙(slot)、微时隙(micro-slot)、迷你时隙(mini-slot)或者符号等，对此不作限定。
8、slot。作为一种时间单元，一个slot的时长可以与子载波间隔的大小相关，不同大小的子载波间隔对应的slot的时长是不同的。例如，子载波间隔为15kHz时，一个时隙的时长可以为1毫秒(millisecond，ms)；子载波间隔为30kHz时，一个时隙的时长可以为0.5ms。示例的，本申请实施例中一个slot可以包括一个或多个符号。比如，正常(normal)循环前缀(cyclic prefix，CP)下，一个时隙可以包括14个符号；扩展(extended)CP下，一个时隙可以包括12个符号。
如图1所示，网络设备10通过波束扫描的方式向终端设备(1、2、...)广播一个或多个同步信号块(synchronization signal block,SSB)，例如，SSB1、SSB2、……、SSB4，以使得终端设备找到合适的SSB完成初始接入过程。
初始接入的目的在于使得终端设备获得与网络设备的下行同步、获取终端设备所在小区的系统信息。下面以图1中的终端设备1为例，结合图3简单介绍一下终端设备1的初始接入过程：
终端设备1搜索并获取SSB，其可以是图1中的SSB1、SSB2、……、SSB4中的一个，示例的，终端设备1可以以接收SSB的质量为依据，选择并获取能接收到的SSB中信号质量最好的一个SSB。
SSB中包含主同步信号(primary synchronization signal,PSS)、辅同步信号(secondary synchronization signal,SSS)和物理广播信道(physical broadcast channel,PBCH)信号。当终端设备1获取到SSB，也即获取到了SSB中的PSS和SSS，则可以认为终端设备1获得了与网络设备的下行同步。终端设备1还可以从PBCH信号中读取主信息块(master information block,MIB)。MIB中包括控制信道配置信息pdcch-config，终端设备通过pdcch-config确定公共搜索空间(common search space,CSS)0和控制资源集合(control resource set,CORESET)0。其中，CSS0用于确定初始接入过程中对位于物理下行控制信道(physical downlink control channel,PDCCH)的下行控制信息(downlink control information,DCI)进行盲检的时域起始位置，而CORESET0用于确定初始接入过程中对位于PDCCH的DCI进行盲检的频域资源和时域资源的长度。例如，如图3所示，实线箭头所指向的时间单元即为通过SSB确定的CSS0和CORESET0，终端设备1在该CSS0和CORESET0中通过盲检得到由系统信息无线网络临时标识(system information-radio network temporary identifier,SI-RNTI)加扰的DCI。其中，由SI-RNTI加扰的DCI表明该DCI的作用是调度 系统信息块(system informationblock,SIB)。最后，终端设备1根据DCI的指示，获取其所在小区的SIB(例如，SIB1)。
进一步地，由SI-RNTI加扰的DCI中可以包括如下表1所示的字段以及每个字段的比特数：
表1
Figure PCTCN2019130272-appb-000001
其中，频域资源分配用于指示由SI-RNTI加扰的DCI所调度数据信道，例如物理下行共享信道(physical downlink shared channel,PDSCH)，的频域位置。频域资源指示的方式包括类型0和类型1。类型0为非连续频域资源分配，类型1为连续频域资源分配。SI-RNTI加扰的DCI目前支持类型1的频域资源分配，其通过资源指示值(resource indication value，RIV)确定数据信道频域资源的起始位置和长度。也即，RIV的值由频域资源分配字段给出。通过下述公式(1)可以计算出数据信道频域资源的起始位置RB start和长度L RBs：
当
Figure PCTCN2019130272-appb-000002
时，RIV＝N*(L RBs-1)+RB start；
当
Figure PCTCN2019130272-appb-000003
时，RIV＝N*(N-L RBs+1)+(N-1-RB start)公式(1)
其中，N为BWP包括的物理资源块RB个数。通过RB start和L RBs，可以获得该DCI所调度数据信道的频域资源。
时域资源分配用于指示由SI-RNTI加扰的DCI所调度数据信道的时域资源。主要通过时域资源分配字段对预定义的表格中的某一行进行指示，从而获得该DCI调度数据信道的时域资源。时域资源分配字段可以为行索引(row index)。下面的表2中，一个row index可以对应到多个解调参考信号(demodulation reference signal,DMRS)位置，(DMRS的位置可以携带在MIB消息中通知给终端设备)。row index和DMRS位置可以共同决定PDSCH映射类型(Type A或Type B)、表示时隙(slot)偏移值K0，即DCI所在的slot与其调度的数 据信道所在的slot的时域偏移值、表示在slot中起始符号的索引值的S、表示占用的符号数的L，即时长。
表2
Figure PCTCN2019130272-appb-000004
根据表2，例如，时域资源分配字段的值(即row index)为1，若DMRS的位置为2，则通过查询表2可以获得K0＝0、S＝2、L＝12，即该DCI所调度的数据信道的时域位置为该DCI所在的slot的第3至14个符号。另外，从表2中可以看出，现有技术中K0值均为0，也就是说DCI与其调度的数据信道在同一slot。
如前所述，为了更好的适配不同类型的业务需求，考虑引入与现有技术已有终端设备类型不同的终端设备，例如前述提及的NR-light终端设备。若引入该类型终端设备，则图1所示的系统架构示意图可以更新为图4。相对于图1，图4中加入了终端设备3，其中终端设备1和2为普通终端设备，而终端设备3为NR-light终端设备。
需要说明的是，本申请实施例所述的NR-light终端设备和普通终端设备仅仅是用于称呼两种不同类型的终端设备，以便于本申请技术方案的表述和理解。本申请实施例可以应用于其他类型的终端设备。
如前所述的初始接入过程中，由SI-RNTI加扰的DCI指示的数据信道的时频资源只能用于使普通终端设备获取属于它的SIB，而属于NR-light终端设备的SIB位于与普通终端 设备不同的数据信道，NR-light终端设备如何获取属于自己的SIB是亟需解决的问题。
需要说明的是下述实施例一至实施例五的场景是类似的，第一终端设备、第一数据信道、第二终端设备、第二数据信道、第一时间单元、第二时间单元以及位于第一数据信道的信号的特征、性质、举例等也与实施例一中相同，各个参数如，RIV、RIV’、K0、K0’、F、S、S’、S”、L、L’、和L”等以及各种名称的信息，如若无其它说明，在各个实施例中的定义相同，因此若在某一实施例中已经有过描述，则在其它实施例中不再赘述。特别的，实施例六中，除了特别说明的术语和参数外，其余术语和参数都与其它实施例中相同或者类似。
实施例一
在尽可能地复用现有机制的情况下，为了使NR-light终端设备能够获取到属于自己的SIB，本申请实施例提出了一种通信方法，通过至少复用普通终端设备的一部分信息，使得NR-light终端设备能够低开销地获取属于自己的SIB。该方法具有良好的后向兼容性。
下面以图4所示的系统架构示意图为例，对本申请实施例一的通信方法进行详细介绍。
示例的，如图5所示，为本申请实施例一提供的一种通信方法的示意图，具体包括以下步骤。
步骤501、网络设备向第一终端设备发送DCI，所述DCI包括：时域资源信息，所述时域资源信息用于确定时域资源，所述时域资源为第一数据信道所在的时域资源；频域资源信息，所述频域资源信息用于确定频域资源，所述频域资源为所述第一数据信道所在的频域资源以及第二数据信道所在的频域资源；所述第二数据信道位于与所述第一数据信道所在的时域资源不同的时域资源。
对应的，所述第一终端设备接收所述DCI，并根据DCI确定所述第一数据信道的时域资源和频域资源。
步骤502、所述第一终端设备在确定的所述时域资源和所述频域资源上，接收来自所述网络设备、位于所述第一数据信道的信号。
以上步骤中提及的第一终端设备，可以为图4中的终端设备3，即可以为NR-light终端设备。上述步骤可以发生在第一终端设备进行初始接入、以获取SIB的过程中。此时，第一数据信道可以为承载SIB的PDSCH，而位于第一数据信道的信号即为SIB。
为了获取SIB，第一终端设备需要确定第一数据信道的时域资源和频域资源，从而在一块确定的时频资源上接收SIB，完成初始接入。步骤501中网络设备向第一终端发送的DCI可以提供确定第一数据信道的时域资源的时域资源信息和确定第一数据信道的频域资源的频域资源信息。也即，第一终端设备可以基于步骤501中接收到的DCI，确定第一数据信道的时域资源和频域资源。特别的，频域资源信息确定的频域资源不仅仅是第一数据信道所在的频域资源，还是另一个数据信道，即第二数据信道所在的频域资源。这里需要进一步说明的是第二数据信道也可以为承载SIB的PDSCH，不过第一数据信道是用于第一终端设备与网络设备进行通信的，而第二数据信道是用于另一个终端设备，即第二终端设备与网络设备通信的，也就是说第一终端设备需要获取的SIB位于第一数据信道，第二终端设备需要获取的SIB位于第二数据信道。这里第一终端设备和第二终端设备可以为不同类型的终端设备。示例的，第一终端设备为NR-light终端设备，第二终端设备为普通终 端设备。可以通过DCI中已经存在的字段对第二数据信道进行指示。从上可以看出，用于指示第一数据信道的频域资源的频域资源信息复用了第二终端设备的频域资源信息。
可选的，频域资源信息即为前述表1中已有的频域资源分配字段的信息。
作为一种实现方式，时域资源信息具体包括如下信息：
1)时域偏移信息，可以用时域偏移值K0’表示，第一终端设备根据K0’可以确定DCI所在的时间单元与第一时间单元的时域间隔，其中当K0'＝0，第一时间单元为第一数据信道所在的时间单元。当K0’大于0，则DCI所在的时间单元与第一时间单元不同；
2)时域起始位置信息，可以用时域起始符号索引值S’表示，第一终端设备根据S’可以确定第一位置，第一位置为所述第一数据信道在所述第一时间单元的时域起始位置，S’为大于或等于0的整数；以及
3)持续时间信息，可以用占用的符号数L’表示，第一终端根据L’可以确定第一时长，第一时长为所述第一数据信道在所述第一时间单元占用的时长，L’为大于或等于0的整数。
可选的，K0’、S’和L’可以是独立于现有表1中时域资源分配字段的信息、是新增字段中的信息。比如，该新增字段位于表1中的保留比特字段。K0’、S’和L’只有第一终端设备可以读取。若与第一终端设备不同类型的第二终端设备也接收了该DCI，则第二终端设备将不会读取该保留比特字段中的信息，也即无法获取K0’、S’和L’。
作为一种示例，第一终端设备和网络设备可以预先约定一张新表格，部分或全部内容与表2相同，例如，下表3：
表3
row index K0’ S’ L’
1 1 2 12
2 2 3 11
3 3 2 10
4 4 3 9
5 1 2 9
6 2 3 8
7 3 2 7
8 4 3 6
9 1 2 5
10 2 3 4
11 3 9 4
12 4 10 4
13 1 4 4
14 2 6 4
15 3 5 7
16 4 5 2
该表格中至少包含row index和与其对应的K0’、S’和L’。那么时域资源信息可以是位于DCI保留比特字段的A个比特，该A个比特可以对应到一个row index(A表示一个整数值)。第一终端设备通过查询该表3即可获得K0’、S’和L’，由此第一终端设备即可以确定出第一数据信道所位于的第一时间单元，以及第一数据信道在该第一时间单元中的具 体位置。参见图6，举例来说，假设时间单元具体为slot，第一终端设备可以根据实施例一开始处所述的方式读取DCI，DCI中的保留字段(例如，15个比特)中包含对应row index的A个比特，若通过其对应到的row index的值2，查表3获得K0’＝2，S’＝3，L’＝11，那么第一数据信道位于DCI所在slot后的第二个slot中的第4至14个符号。
可选的，第一数据信道中的解调参考信号DMRS在第一时间单元中的具体位置，可以默认与第二数据信道中DMRS在第二时间单元中的具体位置相同。作为一种实现方式，与表2类似，还可以在该新表格中，例如表3中，中添加一列表示DMRS的位置，例如表格中的每一个row index至少可以对应一个DMRS在第二时间单元中的具体位置。特别的，第二终端设备是普通终端设备，如前所述，DCI中的时域资源分配确定第二数据信道的时域资源所对应的K0＝0，而K0’大于0，说明第一数据信道和第二数据信道位于不同的时间单元(例如位于不同的slot)，也就是说，第一数据信道和第二数据信道各自都可以拥有足够的时域资源来承载信号。另外，对于第一数据信道来说，由于其还不与承载DCI的PDCCH位于同一时间单元，那么第一数据信道能够占用更多的时域资源，也即承载的信号的信息量将可以更大。
可选的，K0’可以是独立于现有表1中时域资源分配字段的信息，而S’和L’复用现有表1中从时域资源分配字段中获得的S和L，也即S’＝S,L’＝L。换句话说，上述第一位置还为第二数据信道所在的第二时间单元的时域起始位置、上述第一时长还为第二数据信道所在的第二时间单元占用的时长，其中，第二时间单元为第二数据信道所在的时间单元。此时，不仅确定第一数据信道的频域资源的频域资源信息复用了第二终端设备的频域资源信息，确定第一数据信道的时域资源的时域资源信息中的部分也复用了第二终端设备的部分时域资源信息，从而进一步降低了DCI信令的开销。该场景下，只有K0’是位于保留比特字段的新信息。类似的，只有第一终端设备可以读取K0’，与第一终端设备不同类型的第二终端设备将无法读取K0’。作为一种示例，保留比特字段中的B个比特用于指示一个K0’(B为整数值)，第一终端设备可以通过K0’确定出第一数据信道所位于的第一时间单元。比如，B个比特为2个比特(即B＝2)，对应指示4个可能的K0’：1、2、3、4，当然4个可能的K0’也可以通过第一终端设备与网络设备预先约定、或者以协议中约定的方式确定。
可选的，当上述A个比特或者B个比特的值为0时，或者说A个比特或者B个比特缺省时，可以使用第一终端设备和网络设备可以预先约定好的时域资源作为第一数据信道的时域资源。如此可以最大限度的节省系统开销。
实施例二
需要说明的是，实施例一中的技术方案，是在默认第一数据信道位于与DCI和第二数据信道相同的BWP的基础上实施的。实际上第一数据信道还可以位于与DCI和第二数据信道不同的BWP，也即此时第一数据信道位于第一BWP，DCI和第二数据信道位于第二BWP。本申请实施例二针对此情况提供了另一种通信方法，用于实现由同一DCI指示两种不同类型的终端设备的数据信道，保证了前向的兼容性。进一步地，由于第一终端设备的第一数据信道位于与第二终端设备的第二数据信道不同的第二BWP，也就是说，第一终端设备与第二终端设备在不同的BWP上完成剩余的初始接入过程和随机接入过程，使得在同一BWP上进行随机接入的终端设备数目减少，进而有效减低同一BWP上随机接入的冲 突概率。不仅如此，当第一终端设备切换到与第二BWP不同之后，若网络设备想要寻呼的是在第二BWP上通信的终端设备，那么第一终端设备将不会接收到不必要的寻呼消息，从而使得寻呼更有针对性，降低了整个系统的开销。
示例的，如图7所示，为本申请实施例二提供的一种通信方法的示意图，具体包括以下步骤。
步骤701、网络设备在第二BWP上向第一终端设备发送DCI，所述DCI包括BWP信息，所述BWP信息用于确定第一BWP，第一数据信道位于第一BWP。
对应的，第一终端设备在第二BWP上接收DCI，并根据所述DCI包括的BWP信息，确定所述第一BWP和第一数据信道。
步骤702、第一终端设备在确定的第一BWP上，接收来自所述网络设备、位于第一数据信道的信号。
结合图8所示，通过步骤702中在第二BWP上接收DCI，第一终端设备可以获取到DCI中包括的BWP信息，从而确定出第一BWP的位置，并在第一BWP上从第一数据信道获取到信号。例如，该信号即为SIB，则第一终端设备能够完成初始接入。
在一种实现方式中，BWP信息可以包括如下信息中的任一种：
1)BWP偏移信息；
2)BWP偏移信息和第一BWP带宽信息；
3)第一BWP起始位置信息和第一BWP带宽信息。
其中，第一终端设备可以根据BWP偏移信息确定第二BWP与第一BWP之间的频域间隔，例如，为第二BWP的频域起始位置与第一BWP的频域起始位置的频域间隔，或者为第二BWP的频域结束位置与第一BWP的频域结束位置的频域间隔。频域间隔可以用频域偏移值F表示，F大于或者等于0。第一终端设备可以根据第一BWP带宽信息确定第一BWP占用的带宽，比如用占用的带宽可用RB数L”表示。第一终端设备可以根据第一BWP起始位置信息确定第一BWP的频域起始位置，比如用频域起始RB索引值S”表示。
BWP信息可以位于DCI的新增字段，比如可以用前面提到的保留比特字段中的一个或多个比特表示。
可选的，BWP信息可以对应C个比特(C为整数值)。下面分三种情况说明。
在第一种情况下，C个比特可以对应到一个频域偏移值F，例如，通过C个比特直接指示到一个F，或者C个比特指示到一个row index，通过该row index查找预先定义的一张表格再获得相应的F。此时，可以默认第一BWP占用的带宽和第二BWP占用的带宽是相同的，由于第一终端设备知晓了第二BWP的位置，那么根据F，第一终端设备可以确定出第一BWP的具体位置。
在第二种情况下，C个比特可以对应到一个F和一个L”。例如，C个比特中的C1个比特对应一个F,而C2个比特对应一个L”(C＝C1+C2)。由于第一终端设备知晓第二BWP的位置，那么根据F和L”，第一终端设备可以确定出第一BWP的具体位置。例如，F为第二BWP的频域起始位置与第一BWP的频域起始位置的频域间隔，那么第一终端设备根据F确定第一BWP的频域起始位置，在该频域起始位置的基础上，在向后叠加L”，就是第一BWP的位置。
在第三种情况下，C个比特可以对应到一个S”和一个L”。例如，C个比特中的C3个比特对应一个S”,而C4个比特对应一个L”(C＝C3+C4)。该情况下，第一终端设备无需 借助第二BWP的位置信息，便可直接确定出第一BWP的位置，即在S”的基础上向后叠加L”，就是第一BWP的位置。
当L”包括在BWP信息中时，第一BWP的带宽可以根据实际情况进行配置，提高了系统的灵活性。
可选的，当上述C的值为0时，或者说携带BWP信息的C个比特缺省时，可以使用第一终端设备和网络设备可以预先约定好的第一BWP信息确定第一BWP。
进一步的，本申请实施例中第一终端设备还需要在确定第一数据信道在第一BWP上的具体的时域资源和频域资源。
作为一种实现方式，该具体的时域资源和频域资源的确定方式即为实施例一中确定第一数据信道的时域资源和频域资源的方式，具体可以参照实施例一，也即此时可以将实施例一和实施例二进行结合，此处不再赘述。需要说明的是此时BWP信息对应的新增字段和时域资源信息对应的新增字段可以转化为同一新增字段统一指示、也可以仍为分开的不同新增字段。
作为另一种实现方式，第一终端设备可以复用现有表1中的频域资源分配和时域资源分配字段的信息，也即将第二数据信道在第二BWP中的时频资源确定为第一数据信道在第一BWP的时频资源。
可选的，当复用现有表1中的频域资源分配字段，且第一BWP与第二BWP占用的带宽不同时，可以根据如下具体情况进行区分操作：
如图9(a)所示，阴影区域为根据现有的频域资源分配字段获得的第二数据信道在第二BWP中的频域资源。
1)若第一BWP占用的带宽大于第二BWP占用的带宽，则如图9(b)所示，使用与确定第二数据信道在第二BWP中的频域资源相同的方式，可以确定出第一数据信道在第一BWP中频域资源。
2)若第一BWP占用的带宽小于第二BWP占用的带宽，且频域分配字段确定的频域资源长度大于第一BWP占用的带宽，则如图9(c)所示，可以认为第一数据信道的频域资源占满该第一BWP。
3)若第一BWP占用的带宽小于第二BWP占用的带宽，且频域分配字段确定的频域资源长度小于等于第一BWP占用的带宽、频域分配字段确定的频域资源有部分超出第一BWP的范围，则如图9(d)所示，可以认为频域分配字段确定的频域资源起始位置为第一BWP的起始位置，频域资源长度仍然为频域分配字段确定的长度。
如上操作，有助于提高前向兼容性。
实施例三
前述实施例一或者实施例二在确定第一数据信道的具体位置时，至少部分复用了现有的DCI域的相关信息，由此不同程度地降低了DCI的开销。实际上，也可以对确定第一信道位置的各个参数进行单独的指示，该方式对第一数据信道的位置无任何限制，提高了系统的灵活性。
基于以上构思，本申请实施例三提出了如图10所示的一种通信方法，具体包括以下步骤。
步骤1001，网络设备在第二BWP上向第一终端设备发送DCI，所述DCI包括第一信 息，所述第一信息用于确定第一数据信道所位于的第一BWP以及所述第一数据信道在所述第一BWP的时频资源。
对应的，第一终端设备在第二BWP上接收DCI，并根据DCI，确定第一BWP以及第一数据信道在第一BWP的时频资源。
步骤1002、第一终端设备在确定的第一BWP上，接收来自所述网络设备、位于第一数据信道的信号。
作为一种实现方式，第一信息包括：BWP信息、时域资源信息和频域资源信息。其中时域资源信息进一步可以包括：时域偏移信息、时域起始位置信息和持续时间信息。以上这些信息在本实施例中，均通过新增字段进行指示。
例如，第一终端设备和网络设备可以预先约定一张表格，如表4所示：
表4
Figure PCTCN2019130272-appb-000005
表4中频域资源信息表示为RIV’。根据RIV’，参照现有根据频域资源分配确定频域资源的方式，或者使用类似的方式，可以确定第一数据信道的频域资源。示例的，第一信息可以包含D个比特的字段，该D个比特的字段对应到一个row index，第一终端设备通过查询表3即可获得与该row index对应的K0”、L”、S”、K0’、RIV’、S’、和L’。根据F、L”、S”可以确定出第一BWP，根据RIV’确定出第一数据信道的频域资源，根据K0’、S’和L’确定出第一数据信道的时域资源，从而可以在确定的第一BWP上，接收来自所述网络设备、位于第一数据信道的信号。可选的，该第一信息可以为位于DCI的保留比特字段中的D个比特。
实施例四
为了尽可能节省通信资源，在本申请的实施例四中，第一数据信道和第二数据信道不仅是位于同一个BWP，第一数据信道与第二数据信道还位于相同的时间单元。
为了保证第一终端设备与网络设备之间在第一数据信道上的通信、和第二终端设备与网络设备之间在第二数据信道上的通信彼此不相互干扰，需要保证第二数据信道和第一数据信道位于不同的时频资源上。基于上述需求，本申请实施例四提供了如下四种不同的解决方案：
方案一：
如图11(a)所示，第一终端设备默认第一时间单元中所有剩余的时频资源为所述第一数据信道的时频资源。此时，无需在DCI中新增任何字段，其与实施例一中的A个比特或者B个比特缺省时的表现形式是一致的，但是具有与实施例一中A个比特或者B个比 特缺省不同的含义，是不同的方案。
方案一中，网络设备向第一终端设备发送DCI，DCI中的信息指示第二终端设备的第二数据信道的时频资源，第二数据信道位于第一时间单元中的第一时频资源；第一终端设备接收DCI，根据DCI中的信息，在第一时间单元的第二时频资源上，接收第一终端的第一数据信道的信号。其中所述第二时频资源为所述第一时间单元中除去所述第一时频资源的剩余部分。
方案二：
如图11(b)所示，第一终端设备默认第一数据信道与第二数据信道具有相同的时域资源，也即第一终端设备可以复用DCI的时域资源分配确定第一数据信道的时域资源。DCI中需要新增字段用于确定第一数据信道的频域资源，例如该新增字段对应一个RIV’，可以对应确定出一段频域资源。若该RIV’确定的频域资源有部分与第二数据信道重叠，则第一终端设备会跳过这部分频域资源，也即不会试图在与第二数据信道重叠的频域资源上接收第一数据信道的信号。其中，根据RIV’确定频域资源的方式可以参照现有根据频域资源分配确定频域资源的方式，或者使用类似的方式。
方案二中，网络设备向第一终端设备发送DCI，所述DCI包括时域资源信息，所述时域资源信息用于确定第一时域资源，所述第一时域资源为所述第一数据信道所在的时域资源，以及第二数据信道所在的时域资源；频域资源信息，所述频域资源信息用于确定第一频域资源，所述第一频域资源为所述第一数据信道所在的频域资源；所述第二数据信道与所述第一数据信道位于同一时间单元，且所述第一数据信道的频域资源与所述第二数据信道的频域资源不重叠。第一终端设备接收DCI，并根据DCI中的信息，在第一时域资源和第一频域资源上接收来自网络设备、第一数据信道的信号。
方案三：
如图11(c)所示，第一终端设备默认第一数据信道与第二数据信道具有相同的频域资源，也即第一终端设备可以复用DCI的频域资源分配确定第一数据信道的频域资源，DCI中需要新增字段用于确定第一数据信道的时域资源，例如该新增字段对应一个S’和一个L’。若该S’和L’确定的时域资源有部分与第二数据信道重叠，则第一终端设备会跳过这部分时域资源，也即不会试图在与第二数据信道重叠的时域资源上接收第一数据信道的信号。
方案三中，网络设备向第一终端设备发送DCI，所述DCI包括频域资源信息，所述频域资源信息用于确定第一频域资源，所述第一频域资源为所述第一数据信道所在的频域资源，以及第二数据信道所在的频域资源；时域资源信息，所述时域资源信息用于确定第一时域资源，所述第一时域资源为所述第一数据信道所在的时域资源；所述第二数据信道与所述第一数据信道位于同一时间单元，且所述第一数据信道的频域资源与所述第二数据信道的时域资源不重叠。第一终端设备接收DCI，并根据DCI中的信息，在第一时域资源和第一频域资源上接收来自网络设备、第一数据信道的信号。
方案四：
如图11(d)所示，DCI中需要新增字段用于确定第一数据信道的时域资源和频域资源，也即不复用现有DCI中的频域资源分配字段和时域资源分配字段。例如该新增字段可以对应到一个RIV’、一个S’和一个L’，根据RIV’确定第一数据信道的频域资源，以及根据S’和L’确定第一数据信道的时域资源，它们的确定方式在前述已经给出。若该RIV’值确定的频域资源有部分与第二数据信道重叠，则第一终端设备会跳过这部分频域资源，也 即不会试图在与第二数据信道重叠的频域资源上接收第一数据信道的信号。若该S’和L’确定的时域资源有部分与第二数据信道重叠，则第一终端设备会跳过这部分时域资源，也即不会试图在与第二数据信道重叠的时域资源上接收第一数据信道的信号。
方案四中，网络设备向第一终端设备发送DCI，所述DCI包括频域资源信息，所述频域资源信息用于确定第一频域资源，所述第一频域资源为所述第一数据信道所在的频域资源；时域资源信息，所述时域资源信息用于确定第一时域资源，所述第一时域资源为所述第一数据信道所在的时域资源；所述第二数据信道与所述第一数据信道位于同一时间单元，且所述第一数据信道的时频资源与所述第二数据信道的时频域资源不重叠。第一终端设备接收DCI，并根据DCI中的信息，在第一时域资源和第一频域资源上接收来自网络设备、第一数据信道的信号。
作为一种实现方式，上述方案二至四中所述的新增字段可以位于DCI中的保留比特字段。
实施例五
前述实施例一至实施例四分别提供的技术方案中，第一数据信道和第二数据信道在时域上可以位于同一时间单元，或者位于不同的时间单元。为了便于第一终端设备解读DCI中的各个字段，本申请实施例五基于前述各个实施例，提出了一种机制，供第一终端设备确定第一数据信道与第二数据信道是否位于同一时间单元。
作为一种实现方式，可以通过新增字段包含该确认信息，比如位于DCI中的保留字段，用于确定第一数据信道和第二数据信道是否位于同一时间单元。示例的，该新增字段包括1个比特，该比特的值为“1”时，第一终端设备确定第一数据信道和第二数据信道位于同一时间单元；该比特的值为“0”时，第一终端设备确定第一数据信道和第二数据信道位于不同时间单元。该方式的好处是直接明确，无需第一终端设备做大量的信息处理和判断。
作为另一种实现方式，可以通过现有表1所示DCI中频域资源分配字段和/或时域分配字段确定第一数据信道与第二数据信道是否位于同一时间单元。具体地，进一步分为如下几种可能：
1)通过时域资源分配字段确定。时域资源分配字段可以确定第二数据信道S和L值。示例的，当S和/或L大于(或小于)某一阈值时，第一终端设备可以确定第一数据信道与第二数据信道位于同一时间单元，反之，第一终端设备确定第一数据信道与第二数据信道位于不同时间单元。又示例的，当S和/或L为奇数(或者偶数)时，第一终端设备确定第一数据信道与第二数据信道位于同一时间单元，反之，第一终端设备确定第一数据信道与第二数据信道位于不同时间单元。
2)通过频域资源分配字段确定。频域资源分配字段可以确定第二数据信道S”和L”值。示例的，当S”和/或L”大于(或小于)某一阈值，第一终端设备可以确定第一数据信道与第二数据信道位于同一时间单元，反之，第一终端设备确定第一数据信道与第二数据信道位于不同时间单元。又示例的，当S”和/或L”为奇数(或者偶数)时，第一终端设备确定第一数据信道与第二数据信道位于同一时间单元，反之，第一终端设备确定第一数据信道与第二数据信道位于不同时间单元。
3)通过频域资源分配字段和时域资源分配字段结合确定，根据频域资源分配字段和时域资源分配字段可以确定第二数据信道占用时频资源的总量。示例的，当第二数据信道 占用时频资源的总量大于(或小于)某一阈值，第一终端设备可以确定第一数据信道与第二数据信道位于同一时间单元，反之，第一终端设备确定第一数据信道与第二数据信道位于不同时间单元。又示例的，当第二数据信道占用时频资源的总量为奇数(或者偶数)时，第一终端设备可以确定第一数据信道与第二数据信道位于同一时间单元，反之，第一终端设备确定第一数据信道与第二数据信道位于不同时间单元。
上述指示方式的好处是无需新增额外字段，有助于降低系统开销。
实施例六
本申请的实施例一至五除了涉及上述初始接入流程之外，还可以扩展至寻呼流程。现有技术中，终端设备可以通过接收网络设备发送的由寻呼无线网络临时标识(paging-radio network temporary identifier,P-RNTI)加扰的DCI来获取寻呼消息所在数据信道的时频资源。具体的由P-RNTI加扰的DCI所包含的字段与由SI-RNTI加扰的DCI类似，也至少包含频域资源分配字段、时域分配字段和保留比特字段。其中，对由P-RNTI加扰的DCI调度所数据信道的时域资源和频域资源的指示方式与由SI-RNTI加扰的DCI调度所数据信道的时域资源和频域资源的指示方式是一致的，可以参照相关段落的表述，此处不再赘述。
相对于现有技术来说，本申请实施例不仅仅期望网络设备发送的由P-RNTI加扰的DCI可以指示寻呼消息所在的数据信道的时频资源，还期望由P-RNTI加扰的DCI同时可以指示到网络设备向终端设备发送下行微量数据(small data)所在的数据信道的时频资源。如此尽可能的减少系统中DCI的开销。
基于如上需求，本申请实施例六对实施例一至五的应用场景进行扩展，也即从应用于初始接入流程扩展到寻呼流程。需要说明的是实施例一至五中所指的第一数据信道在实施例六中可以为承载下行small data的PDSCH、第二数据信道可以为承载寻呼消息的PDSCH、以及位于第一数据信道的信号可以是下行small data。而接收由P-RNTI加扰的DCI的终端设备可以为实施例一至五中的第一终端设备，或者第二终端设备，也即可以理解为某一类型的终端设备，可以为NR-light终端设备等区别于现有普通终端设备的新型终端设备，还可以为现有普通终端设备，本实施例是对其性能的进一步改进。
与实施例一至五所述的第一终端设备不同的是，本申请实施例中的终端设备会接收位于第一数据信道的信号，也即下行small data，还会接收位于第二数据信道的信号，也即寻呼消息。不过由P-RNTI加扰的DCI对第一数据信道所在的时频资源的指示方式本身与实施例一至五是一致的，其方法流程可以参照前述实施例，因此本申请实施例中不再赘述，只是抽取其中一种指示方式结合图12做简单介绍，以便于理解。
如前所述，步骤501中的时域资源信息具体包括K0’、S’和L’，例如在图12中K0’＝2，S’＝3，L’＝11。K0’、S’和L’可以是独立于现有表1中时域资源分配字段的信息、是新增字段中的信息。比如，该新增字段位于由P-RNTI加扰的DCI的保留比特字段。本申请实施例六中的终端设备被配置为可以读取包括保留比特字段在内的所有DCI的字段。如此该终端设备不仅仅可以获取到K0、S和L，还可以按照实施例一中所述的方式获取到K0’、S’和L’。同时由于用于指示第一数据信道和第二数据信道的频域资源的频域资源信息可以通过由P-RNTI加扰的DCI的频域分配字段获得，该终端设备可以根据确定的频域资源和确定的时域资源信息，接收位于第一数据信道的接收下行small data，同时根据现有技术接收位于第二数据 信道的寻呼消息。
关于实施例一至五中其余的技术方案，都可以类似地、毫无障碍的引入实施例六中的场景，其对本领域技术人员来说是可以理解的。
通过一个DCI指示终端设备的两个数据信道，本申请实施例可以有效降低系统开销，提高资源的利用率。也可以解决承载寻呼消息的信道容量不足的问题。
上述本申请提供的实施例中，从终端设备作为执行主体的角度对本申请实施例提供的通信方法进行了介绍。为了实现上述本申请实施例提供的通信方法中的各功能，终端设备可以包括硬件结构和/或软件模块，以硬件结构、软件模块、或硬件结构加软件模块的形式来实现上述各功能。上述各功能中的某个功能以硬件结构、软件模块、还是硬件结构加软件模块的方式来执行，取决于技术方案的特定应用和设计约束条件。

关于收发模块1301、处理模块1302的具体执行过程，可参见上实施例一中的记载。本申请实施例中对模块的划分是示意性的，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式。另外，在本申请各个实施例中的各功能模块可以集成在一个处理器中，也可以是单独物理存在，也可以两个或两个以上模块集成在一个模块中。上述集成的模块既可以采用硬件的形式实现，也可以采用软件功能模块的形式实现。
可以理解的是，装置1300还可以用于实现实施例二至实施例六中第一终端设备和网络设备的功能。本领域技术人员结合上述装置实施例的描述和实施例二至实施例六中的过程描述，无需经过创造性的劳动，就可以很容易得到用于实现实施例二至实施例六中的终端设备和网络设备的装置实施例，在此不加赘述。

图15为电子设备的通用结构示意图。如前所述，第一终端设备可以是NR-light终端设备。相对于普通的终端设备，NR-light终端设备的制造成本较低，并且与网络设备通信的带宽较低、功耗也较低。也就是说，NR-light终端设备可以包括如图15所示的电子设备1500的部分或全部元器件。以下对图15中的电子设备1500做详细介绍。
