接入网设备102可以与多个终端设备(例如终端设备116和终端设备122)通信。然而,可以理解,接入网设备102可以与类似于终端设备116或终端设备122的任意数目的终端设备通信。终端设备116和122可以是例如蜂窝电话、智能电话、便携式电脑、手持通信设备、手持计算设备、卫星无线电装置、全球定位系统、PDA和/或用于在无线通信系统100上通信的任意其它适合设备。
如图1所示,终端设备116与天线112和114通信,其中天线112和114通过前向链路(也称为下行链路)118向终端设备116发送信息,并通过反向链路(也称为上行链路)120从终端设备116接收信息。此外,终端设备122与天线104和106通信,其中天线104和106通过前向链路124向终端设备122发送信息,并通过反向链路126从终端设备122接收信息。
例如,在频分双工(Frequency Division Duplex,FDD)系统中,例如,前向链路118可与反向链路120使用不同的频带,前向链路124可与反向链路126使用不同的频带。
再例如,在时分双工(Time Division Duplex,TDD)系统和全双工(Full Duplex)系统中,前向链路118和反向链路120可使用共同频带,前向链路124和反向链路126可使用共同频带。
被设计用于通信的每个天线(或者由多个天线组成的天线组)和/或区域称为接入网设备102的扇区。例如,可将天线组设计为与接入网设备102覆盖区域的扇区中的终端设备通信。接入网设备可以通过单个天线或多天线发射分集向其对应的扇区内所有的终端设备发送信号。在接入网设备102通过前向链路118和124分别与终端设备116和122进行通信的过程中,接入网设备102的发射天线也可利用波束成形来改善前向链路118和124的信噪比。此外,与接入网设备通过单个天线或多天线发射分集向它所有的 终端设备发送信号的方式相比,在接入网设备102利用波束成形向相关覆盖区域中随机分散的终端设备116和122发送信号时,相邻小区中的移动设备会受到较少的干扰。
在给定时间,接入网设备102、终端设备116或终端设备122可以是无线通信发送装置和/或无线通信接收装置。当发送数据时,无线通信发送装置可对数据进行编码以用于传输。具体地,无线通信发送装置可获取(例如生成、从其它通信装置接收、或在存储器中保存等)要通过信道发送至无线通信接收装置的一定数目的数据比特。这种数据比特可包含在数据的传输块(或多个传输块)中,传输块可被分段以产生多个码块。
此外,该通信系统100可以是PLMN网络、D2D网络、M2M网络、IoT网络或者其他网络,图1只是举例的简化示意图,网络中还可以包括其他接入网设备,图1中未予以画出。
络中的网络设备或者未来演进的PLMN网络中的网络设备等,本申请实施例并不限定。
作为实例而非限定,本申请的传输数据的方法可以应用于车联网系统,车联网(V2X)的研究范围包括车与车(V2V)通信、车与行人(V2P)通信以及车与基础设施网络(V2I)通信。V2X中的通信既可以基于旁路(Sidelink)接口实现,也可以基于Uu接口实现。当前,车辆网系统可以支持最多8个PC5载波,其中,PC5是协议架构中用于UE与UE之间进行设备间发现和设备间通信的参考点的载波聚合。
图2描述了车联网通信系统的示意图,其中终端之间可以通过sidelink接口直接通信,当终端处于网络设备如基站的信号覆盖范围内时,终端可与基站通信。
目前,车辆网系统可以包括以下三种多载波使用场景:
场景1:多个媒体接入控制协议数据单元(Medium Access Control Protocol Data Unit,MAC PDU)并行传输。其中,“并行”传输包括在不同的载波上同时或不同时传输。在各个载波上传输的MAC PDU负荷不同;
场景2:相同的数据包在不同载波上并行重复传输。其中,“并行”传输包括在不同的载波上同时或不同时传输。
场景3:从接收设备角度考虑的容量提升。从接收设备来看,假设其可以在多个载波上同时接收。从发送设备来看,可以在一组载波上发送。比如,某个UE在单个载波上发送(对各个UE来说,可能载波不同),但可以在所有载波上接收,此时接收UE可以发现更多的其他UE,也就意味着信道容量增加。
在当前的V2X技术中,UE仅在一个载波上发送旁路控制信息(Sidelink Control Information,SCI)和数据,其中旁路控制信息在物理旁路控制信道(Physical Sidelink Control Channel,PSCCH)上传输,数据(Data)在物理旁路共享信道(Physical Sidelink Shared Channel,PSSCH)上传输。在当前的V2X技术中,旁路控制信息和数据(Data)总是成对出现,即PSSCH上传输的每个Data分组都有对应的控制信息在PSCCH上传输,用以指示该数据包的传输资源;在未来的V2X演进技术中,也可能旁路控制信息和Data没有一一对应的关系,例如,可能有公共的控制信息,但不指示具体某个数据包的传输资源。在本发明的实施例中,在不产生概念混淆的情况下,数据是一种广义概念,可以表示控制信道上传输的控制信息,也可以表示共享信道上传输的数据,还可以同时表示控制信道上传输的控制信息以及共享信道上传输的数据。在3GPP V2X标准中,UE发送SCI可以表述为UE传输PSCCH(transmit the PSCCH),UE发送Data可以表述为UE传输PSSCH(transmit the PSSCH),因此,本发明实施例中,UE传输数据也可以表示UE传输PSCCH、UE传输PSSCH、UE传输PSCCH和UE传输PSSCH中的一种。UE发送的旁路控制信息仅指示该UE在未来一段时间内在该载波上传输SCI和Data时预留的资源,不能指示在其他载波上的预留资源。因此,按照现在的资源预留指示方法,当某个UE在多个载波上传输时,接收端需要在多个载波上进行盲检测才能知道对应UE是否在多个载波上预留的资源以及其预留的资源位置。对 于接收能力有限的终端而言,可能需要切换载波,而盲目的切换会导致接收能力下降,因为切换到某个载波会导致错过另一个载波上的车联网信息,此时,如果发送端UE能指示其跨载波调度信息,则可减少接收端的盲检测和盲切换。另外,对于支持多载波能力有限的终端而言,如果在资源选择时,可以获得其他UE在其他载波上的资源预留信息,则该UE可依据这些指示信息在对应载波上进行资源选择,从而可以减少在其他载波上侦听所带来的能量消耗。此外,未来可能支持一个大数据包在多个载波上传输,此时为了便于接收端UE接收与合并多个载波上的数据包,需要发送方UE指示跨载波调度信息。在这些场景中,都需要设计跨载波指示方式。本申请的方案可以应用于车联网系统的多载波传输过程。
下面,对该通信系统100所使用的用于无线通信的时频资源进行详细说明。
在本发明实施例中,时频资源可以包括时域、频域、空域和码域等多个维度。
例如,本申请中,时频资源在时域上可以划分为多个时间单元。

再例如,本申请中,时频资源在频域上可以被划分为多个载波或者多个频段。
并且,每个载波或者频段可以被划分为多个子载波。
其中,由一个子载波和一个符号唯一确定的时频资源可以被称为资源单元(Resource Element,RE),处于规定的时频范围和频域范围内的多个RE可以构成资源块(Resource Block,RB)。

作为示例而非限定,在本申请实施例中,该载波#A可以通过以下至少一种方式确定。
方式a
在本申请实施例中,该载波#A可以是通信系统或通信协议规定的载波。
例如,通信系统或通信协议可以配置该M个载波中的某一个载波为调度载波,该调度载波可以用于承载发送设备所发送的用于指示该发送设备发送数据时使用的载波的信息,例如,上述信息#A,从而,设备#A可以将该调度载波确定为载波#A,并且,设备#B可以在该调度载波上检测设备#A所发送的信息 #A。
并且,作为实例而非限定,当该M个载波包括主载波和辅载波的情况下,该载波#A可以是该M个载波中的主载波。
其中,该主载波可以是该通信系统配置的公共载波。

此情况下,设备#A可以通过该载波#A发送标识#α,从而,当设备#B在载波#A中检测到该标识#α时,可以确定该载波#A中携带有上述信息#A。
作为示例而非限定,例如,该标识#α可以承载于SCI中的资源预留(Resource reservation)字段(或者,也可以称为“域”)中,此情况下,该标识#α的值可以包括但不限于“1101”、“1110”或者“1111”中的一个。
再例如,该标识#α可以承载于SCI中的调制与编码方式(Modulation and coding scheme,MCS)字段中。需要说明的是,由于该标识#α占用了MCS字段,因此,此情况下,传输数据时使用的MCS的值可以为通信系统或通信协议规定的默认值。
再例如,该标识#α可以通过发送设备仅在特定载波(例如载波#A)上发送信息#A来指示,即发送设备不在除特定载波以外的载波上发送信息#A。因此,当设备#B在载波#A上检测到信息#A时,可以确定发送设备在载波#A上通过发送信息#A指示了隐含信息标识#α,从而确定该载波为发送设备的调度载波,即载波#A。
应理解,以上理解的标识#α的发送方式仅为示例性说明,本申请并未特别限定,例如,该标识#α也可以作为独立的信息而被单独发送。
处理方法2
具体地说,通信系统或通信协议可以规定:发送设备仅在调度载波(即,承载有第一信息的载波,该第一信息用于指示该发送设备发送数据时所使用的载波)上发送同步信号,即,在非调度载波(即,未承载第一信息)上不发送同步信号。
此情况下,设备#A可以在该载波#A上发送同步信号,从而,当设备#B在载波#A中检测到同步信号时,可以确定设备#A在该载波#A发送的部分数据中携带有上述信息#A。
处理方法3
具体地说,通信系统或通信协议可以规定一个特定的序列#β(即,第一序列的一例)。该标识#β可 以具有以下功能:当某个设备接收到标识#β对应的同步信号(或者,参考信号)时,该设备可以确定携带有标识#β对应的同步信号的载波中,携带有发送设备发送数据时所使用的载波的指示信息,即,携带有标识#β对应的同步信号的载波可以被确定为调度载波。
作为示例而非限定,例如,该同步信号可以为旁路主同步信号(Primary Sidelink Synchronization Signal,PSSS),此情况下,该序列#β可以为用于生成该PSSS的序列。
再例如,该同步信号可以为旁路辅同步信号(Secondary Sidelink Synchronization Signal,SSSS),此情况下,该序列#β可以为用于生成该SSSS的序列。
需要说明的是,在本发明实施例中,该载波#A可以属于该N个载波,即,该载波#A可以是设备#A发送数据时所使用的载波。或者,该载波#A也可以不属于该N个载波,即,设备#A在发送数据时不使用该载波#A。
例如,作为实例而非限定,在本发明实施例中,设备#A还可以在载波#A上发送信息#C,该信息#C可以用于指示该载波#A是否被设备#A用来发送数据。并且,作为实例而非限定,该信息#C与信息#A承载于同一消息或信息中,例如,该信息#C与信息#A可以承载于SCI中的不同字段中。或者,该信息#C与信息#A也可以承载于不同的消息或信息中,例如,该信息#A可以承载于SCI中,该信息#C可以承载于数据包的MAC CE中。
或者,通信系统或通信协议可以规定,携带有第一指示信息的载波被用于发送设备发送数据,此情况下,设备#B在通过载波#A接收到信息#A时,可以确定该载波#A被设备#A用于发送数据。
或者,通信系统或通信协议可以规定,携带有第一指示信息的载波不能被用于发送设备发送数据,此情况下,设备#B在通过载波#A接收到信息#A时,可以确定该载波#A不会被设备#A用于发送数据。
由此,通过上述方式,能够实现设备#A和设备#B通过载波#A传输信息#A的过程。
在本申请实施例中,设备#A还可以发送信息#D(即,第二指示信息),该信息#D可以用于指示该N个在载波中被设备#A用来传输数据的时频资源(即,上述时频资源#A1、时频资源#A2、…、时频资源#Ai、…、时频资源#AN)的位置。
其中,该时频资源的位置可以是指时频资源的时域位置,例如,时频资源对应的子帧、时隙或符号等。
或者,该时频资源的位置可以是指时频资源的频域位置,例如,时频资源对应的子载波等。
再或者,该时频资源的位置可以是指时频资源的频域位置和时域位置,例如,时频资源对应的资源单元(Resource Element,RE)、资源块(Resource Block,RB)、资源单元集合(Resource Element Group,REG)资源块集合(Resource Block Group,RBG)等。
