Description

多载频选择方法及相关设备 技术领域
本申请涉及通信领域，尤其涉及一种多载频选择方法及相关设备。
背景技术
全球每年发生大量的交通事故，造成大量的人员伤亡和财产损失。发生交通事故的主要原因在于车辆之间缺乏可靠的信息交互。车联网系统旨在通过车辆与车辆(Vehicle to Vehicle，V2V)，车辆与基础设施/网络之间(Vehical to Infrasture/Network，V2I/N)以及车辆与行人之间(Vehical to Pedestrian，V2P)之间的通信来达到提高道路安全，提高交通效率和为用户提供丰富的流媒体服务的目的。
智能交通系统(Intelligent Transportation System，ITS)对于通信的低时延和高可靠性通信具有严格的要求。第三代合作伙伴计划(3rdGeneration Partner Project，3GPP)蜂窝技术具有时延短、速度快、覆盖率广泛、容量大、可靠性高等优势，因此利用蜂窝技术来实现车联网成为当前的主要趋势。
现有技术中，V2X(V2V、V2I/N、V2P)通信可以采用直连链路通信，即车辆之间进行通信，数据不需要经过基站进行中转，其中车车之间通信的资源来自基站配置或者预配置。其中，车辆之间实现直接通信的链路称为直连链路，也称为侧向链路(Sidelink，SL)。当终端设备在网络覆盖下的时候，直连链路通信的资源来自基站的配置，当终端设备不在网络覆盖下的时候，直连链路通信资源为预配置资源。当终端设备在网络覆盖下的时候，终端之间采用直连链路进行通信，且终端之间的通信资源来自基站配置。当终端设备不在网络覆盖下的时候，终端之间采用直连链路进行通信，且终端之间的通信资源来自预配置。
与传统点对点通信不同，直连链路中信息是一对多通信，而系统中不同的接收端的接收能力是不同的。因此存在系统性能与接收端能力之间的矛盾。在发送端，如果存在多个载频，为了提高系统性能，终端会选择信道拥塞值(Channel Busy Ratio，CBR)比较小的载频来进行资源传输，这样导致发送端在载频选择时会比较发散。而接收端接收链有限，其只能同时接收有限个载频上的数据。如果发送端载频选择比较分散，接收端则无法接收全部数据。
例如，假设终端(User Equipment，UE)1选择在载频3(F3)和载频4(F4)上传输，终端3(UE3)选择在载频1(F1)和载频2(F2)上传输，此时由于终端2(UE2)只有两个接收链，在某个时刻，终端2(UE2)只能接收到终端1(UE1)和终端3(UE3)中的某一个终端的数据，如图1所示；或者在某个时刻，终端2(UE2)只能接收到终端1(UE1)和终端3(UE3)这两个终端上的部分数据，如图2所示。

需要说明的是，本申请实施例中涉及的网络设备：可以是基站，或者接入点，或者可以是指接入网中在空中接口上通过一个或多个扇区与无线终端通信的设备。本申请实施例中以基站为例进行说明。其中，基站例如可以是全球移动通讯(Global System of Mobile communication，GSM)或码分多址(Code Division Multiple Access，CDMA)中的基站(Base Transceiver Station，BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，WCDMA)中的基站(NodeB，NB)，还可以是长期演进(Long Term Evolution，LTE)中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者中继站或接入点，或者未来5G网络中的基站等，在此并不限定。
本申请实施例中涉及的第一终端、第二终端可以是V2X中位于车辆上的终端设备(例如，车载终端设备、乘坐车辆的用户所携带的终端设备)，也可以是位于X(X可以为车辆、基础设施、网络、行人等)上的终端设备，或者可以是车辆终端本身或者X本身。这里所说的终端设备可以是无线终端也可以是有线终端，无线终端可以是指向用户提供语音和/或其他业务数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，无线终端可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，个人通信业务(Personal Communication Service，PCS)电话、无绳电话、会话发起协议(Session Initiation Protocol，SIP)话机、无线本地环路(Wireless Local Loop，WLL)站、个人数字助理(Personal Digital Assistant，PDA)等设备。无线终端也可以称为系统、订户单元(Subscriber Unit)、订户站(Subscriber Station)，移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、用户设备(User Device or User Equipment)，在此不作限定。

接下来结合图3介绍的通信系统，介绍本申请实施例提供的一种多载频选择方法。如图4所示，多载频选择方法至少可以包括以下几个步骤：
S101：基站向第一终端发送第一配置信息。
具体地，第一配置信息可以包括至少一个第一载频信息和对应的第一信道拥塞参数信息。其中，第一载频信息例如可以但不限于是代表一个第一载频标识。第一信道拥塞参数信息例如可以是与第一载频信息对应的，该第一信道拥塞参数信息代表的第一载频的信道拥塞信息。信道拥塞值(Channel Busy Ratio，CBR)用来描述资源集的繁忙程度或资源集的负载程度，例如可以是，在一段时间内，资源集中子信道上的功率超过某个门限的子信道的个数占所有子信道个数的比例。或者在一段时间内，资源集中资源块的功率超过某个门限的资源块的个数占所有资源块个数的比例。需要说明的是，每个第一载频都对应至少 一个资源集，资源集的信道拥塞值可以代表该资源集所属的第一载频对应的信道拥塞值。
可选地，第一信道拥塞信息可以包括第一信道拥塞门限。
可选地，第一信道拥塞信息可以包括第一信道拥塞范围。
可选地，第一配置信息可以包含在基站发送的专用无线资源控制(Radio Resource Control，RRC)信令或者系统消息块(System Information Block，SIB)或者包含在预配置信息中。具体的，预配置信息可以是终端在出厂时预先配置在终端内部的信息，也可以是由网络配置的、终端保存在内部的信息。
S102：第一终端获取第一数据。
具体地，第一数据为待发送数据，即为第一终端准备向至少一个第二终端发送的数据。第一终端可以理解为发送端，第二终端可以理解为接收端。
可以知道的是，S101和S102发生的先后顺序在此不做限定。
S103：第一终端根据第一载频信息、第一信道拥塞参数信息按照优先级顺序为第一数据选择至少一个直连链路传输载频。
具体地，优先级顺序为上述至少一个第一载频信息对应的至少一个第一载频的优先级顺序。此处的优先级顺序可以是上述至少一个第一载频的排列顺序，也可以是第一终端在选择载频时，对上述至少一个第一载频的选择顺序。可以知道的是，此处的优先级顺序不一定是实际存在的优先级顺序，还可以是以其他形式存在的优先级顺序。
具体地，上述优先级顺序可以是基站预先为上述第一终端配置好的参数，明确表示上述第一载频的优先级顺序。上述优先级顺序还可以是第一终端根据各个第一载频的实际CBR值决定的各个第一载频的优先级顺序，即通过各个第一载频对应的信道拥塞值间接决定上述至少一个第一载频的优先级顺序。在一种具体的实现方式中，可以是信道拥塞值越小的第一载频优先级越高，还可以是信道拥塞值在处于一定范围内的第一载频中，信道拥塞值越小的第一载频优先级越高。
在一个可能的实施例中，当第一信道拥塞参数信息包括第一信道拥塞门限时，第一终端可以根据各个第一载频对应的第一信道拥塞门限筛选出至少一个第二载频，然后第一终端再从上述至少一个第二载频中按照优先级顺序为第一数据选择至少一个直连链路传输载频。其中，第二载频对应的信道拥塞值小于或等于第一信道拥塞门限。
在一个可能的实施例中，当第一信道拥塞参数信息包括第一信道拥塞范围时，第一终端可以根据各个第一载频对应的第一信道拥塞门限筛选出至少一个第二载频，然后第一终端再从上述至少一个第二载频中按照优先级顺序为第一数据选择至少一个直连链路传输载频。其中，第二载频对应的信道拥塞值属于第一信道拥塞范围。
在一个可能的实施例中，若上述第一载频的优先级顺序由基站预先为上述第一终端配置好的参数，那么第一终端可以从第二载频中选择优先级最高的至少一个第二载频作为直连链路传输载频。
在一个可能的实施例中，若上述第一载频的优先级顺序由第一终端根据各个第一载频对应的信道拥塞值决定，那么第一终端可以从第二载频中选择信道拥塞值最小的至少一个载频作为直通链路传输载频。
S104：第一终端在直连链路传输载频上向第二终端发送第一数据。
具体地，选定直连链路传输载频后，在该直连链路传输载频上向至少一个第二终端发送第一数据，实现终端与终端之间的数据通信。
可以知道的是，上述第二载频对应的信道拥塞值可以是第一终端测量得到的，也可以由第一终端接收基站向其发送的专用RRC信令或者SIB消息得到。
可以知道的是，上述第二载频对应的信道拥塞值指的是该第二载频对应的第一资源集的信道拥塞值。每个第二载频中可以包括至少一个第一资源集。在一个可能的实施例中，第一资源集可以是一个资源池，资源池中包含至少一个时频资源。在一个可能的实施例中，第二载频对应的第一资源集是指第二载频上的部分或者全部时频资源。具体的，第一资源集可以是连续的，可以是不连续的。
实施本申请实施例，可以通过获取第一配置信息，根据第一载频信息及第一信道拥塞参数信息按照优先级顺序选择至少一个直连链路传输载频，使得第一终端在上述至少一个直连链路传输载频上向至少一个第二终端发送第一数据，在第一终端进行多载频选择时，按照一定的顺序进行选择，使得第一终端选择的传输载频尽量收敛，以使第二终端尽可能多的接收到第一终端发送的数据。
本申请实施例还提供了另外一种多载频选择方法，如图5所示，多载频选择方法至少可以包括以下几个步骤：
S201：基站向第一终端发送第一配置信息。
具体地，S201与S101一致，在此不再赘述。
S202：第一终端获取第一数据。
具体地，S202与S102一致，在此不再赘述。
S203：第一终端获取至少一个第一载频信息对应的至少一个优先级顺序信息。
具体地，优先级顺序信息可以是第一终端通过接收基站向其发送的配置信息或者预配置信息得到的，配置信息或预配置信息中可以明确表明第一载频的优先级顺序。优先级顺序信息也可以是第一终端根据各个第一载频对应的信道拥塞值得到的，即通过各个第一载频对应的信道拥塞值间接决定上述至少一个第一载频的优先级顺序。在一种具体的实现方式中，可以是信道拥塞值越小的第一载频优先级越高，还可以是信道拥塞值在处于一定范围内的第一载频中，信道拥塞值越小的第一载频优先级越高。
在一个可能的实施例中，优先级顺序也可以是隐式的，示例性的，可以通过载频排序体现载频的优先级顺序，例如{F1，F2，F3}，F1优先级高于F2的优先级，F2的优先级高于F3的优先级，或者也可以反向，F3的优先级高于F2的优先级，F2的优先级高于F1的优先级。
在一个可能的实施例中，如果第一载频中存在若干载频，基站为这若干个载频配置的载频的优先级信息相同，终端可以进一步按照该若干个载频对应的信道拥塞值来确定该若干个载频的优先级，其中信道拥塞值越小的载频优先级较高，或者终端可以从该优先级相同的若干个载频中随机选择至少一个载频。例如{F1，F2，F3}基站为F1配置的优先级为1，为F2，F3配置的优先级为2。如果此时F3的信道拥塞值小于F2，则如果终端选择了两个载频，则终端选择的是{F1，F3}；或者对于优先级相同的载频，终端随机从其中选择载 频，则此时结果可能是{F1，F2}或者{F1，F3}。
具体地，S203与S201及S202发生的先后顺序在此不做限定。
需要说明的是，在一个可能的实施例，至少一个第一载频信息对应的至少一个优先级顺序信息可以包含在第一配置信息中，此时终端通过接收第一配置信息也可以获取至少一个第一载频信息对应的至少一个优先级顺序信息，此时步骤S201和步骤S203可以合并。当然，可以理解的，至少一个第一载频信息对应的至少一个优先级顺序信息可以不包含在第一配置信息中。
可选地，至少一个第一载频信息对应的至少一个优先级顺序信息可以包含在基站发送的专用RRC信令或者SIB中或者包含在预配置信息中。具体的，预配置信息可以是终端在出厂时预先配置在终端内部的信息，也可以是由网络配置的、终端保存在内部的信息。
S204：第一终端根据第一载频信息、第一信道拥塞参数信息按照优先级顺序信息为第一数据选择至少一个直连链路传输载频。
具体地，在确定各个第一载频信息对应的优先级顺序信息后，根据该优先级信息表征的各个第一载频的优先级顺序，结合第一载频信息、第一信道拥塞参数信息，为第一数据选择至少一个直连链路传输载频。
S205：第一终端在直连链路传输载频上向第二终端发送第一数据。
具体地，S205与S104一致，在此不再赘述。
本申请实施例提供了多种第一终端获得各个第一载频的优先级顺序信息的方式，第一终端可以根据各个第一载频的优先级顺序信息为第一数据选择传输载频，使第一终端在进行多载频选择时按照一定的顺序进行选择，使第一终端选择的传输载频尽量收敛，以使第二终端尽可能多的接收到第一终端发送的数据。
本申请实施例提供了另外一种多载频选择方法，如图6所示，多载频选择方法至少可以包括以下几个步骤：
S301：基站向第一终端发送第一配置信息。
具体地，S301与S201一致，在此不再赘述。
S302：第一终端获取第一数据。
具体地，S302与S202一致，在此不再赘述。
S303：第一终端获取至少一个第一载频信息对应的至少一个优先级顺序信息。
具体地，S303与S203一致，在此不再赘述。
S304：第一终端获取与第一载频信息和/或第一信道拥塞参数信息对应的第一标识信息。
具体地，第一标识信息包括但不限于是以下至少一种：数据的业务优先级、数据的目的地址、数据的业务类型。
其中，第一终端可以存在多种不同类型的业务。数据的业务类型可以是对应不同接收端的业务，例如上述所说的不同类型的业务可以为V2V业务、V2P业务、V2I业务等。或者，数据的业务类型也可以通过应用层携带的应用层标识，(例如ITS-AID：ITS Application Identifier或者PSID：Provider Service Identifier)来区分，例如不同的应用层标识可以指代 不同的业务，示例性的，ITS-AID1可以表示碰撞预警业务，ITS-AID2可以表示车辆状态异常告警。
其中，第一终端向第二终端发送的数据可以具有不同的业务优先级。不同业务优先级的数据在接入层可以采用不同的传输参数，来区别对待。示例性质的，接入层可以为较高的优先级的数据配置更多的资源，或者允许其采用较低的调制编码策略来保障数据传输的可靠性。
其中第一终端向第二终端发送的数据可以具有不同的目的地址。不同的目的地址可以指向不同的第二终端。示例性的，目的地址可以是组播地址、单播地址或者广播地址。
在一个可能的实现形式中，数据的目的地址可以与数据的业务类型存在映射关系。
可选地，根据第一载频信息可以确定该第一载频信息对应的第一载频，进一步确定该第一载频对应的第一标识信息。
可选地，根据第一信道拥塞参数信息可以确定该第一信道拥塞参数信息对应的第一载频。进一步确定该第一载频对应的第一标识信息。
可选地，根据第一载频信息和第一信道拥塞参数信息可以确定对应的第一载频，进一步确定该第一载频对应的第一标识信息。
具体地，对于不同的第一载频而言，可能会对应不同的第一标识信息，即不同的数据的业务优先级、数据的目的地址、数据的业务类型等。在第一终端获取第一数据之后，可以进一步根据第一数据确定该第一数据的第二标识信息，该第二标识信息包括但不限于以下至少一种：第一数据的业务类型、第一数据的目的地址、第一数据的业务类型等。第一终端根据第一数据的第二标识信息可以获得与之匹配的多个第一载频，这些第一载频的第一标识信息可以包括上述第一数据的第二标识信息。上述第二标识信息可以与第一标识信息相同或者不同，本申请不对此进行限定。
在一个可能的实施例中，第一终端根据第一数据确定第一数据的第二标识信息也可以第一终端根据在获取第一数据时，同时获取的第一数据对应的第二标识信息来确定的。示例性的：第二标识信息可以通过原语传递。
S305：第一终端根据第一标识信息、第一载频信息及第一信道拥塞参数信息按照优先级顺序为第一数据选择至少一个直连链路传输载频。
具体地，首先根据第一标识信息筛选出与第一数据的第二标识信息匹配的多个第一载频。其次，根据第一载频信息及第一信道拥塞参数信息按照优先级顺序从上述多个第一载频中为第一数据选择至少一个直连链路传输载频。
上述多个第一载频的优先级顺序可以参照前述实施例中对于第一载频的优先级顺序的描述，在此不再赘述。
S306：第一终端在直连链路传输载频上向第二终端发送第一数据。
具体地，S306与S205一致，在此不再赘述。
具体地，S301、S302、S303、S304的发生的先后顺序在此不做限定。
需要说明的是，在一个可能的实施例，与第一信道拥塞参数信息对应的第一标识信息可以包含在第一配置信息中，此时终端通过接收第一配置信息也可以获取与第一信道拥塞参数信息对应的第一标识信息，此时步骤S301和步骤S304可以合并。当然，可以理解的， 与第一信道拥塞参数信息对应的第一标识信息可以包含在第一配置信息中可以不包含在第一配置信息中。
需要说明的是，在一个可能的实施例，与第一信道拥塞参数信息对应的第一标识信息与至少一个第一载频信息对应的至少一个优先级顺序信息包含在同一个信息中，例如第二配置信息，此时终端通过接收第二配置信息可以获得与第一信道拥塞参数信息对应的第一标识信息和至少一个第一载频信息对应的至少一个优先级顺序信息，此时步骤S303和步骤S304可以合并。当然，可以理解的，与第一信道拥塞参数信息对应的第一标识信息也可以不与至少一个第一载频信息对应的至少一个优先级顺序信息包含同一信息中。
可选地，与第一信道拥塞参数信息对应的第一标识信息可以包含在基站发送的专用RRC信令或者SIB中或者包含在预配置信息中。具体的，预配置信息可以是终端在出厂时预先配置在终端内部的信息，也可以是由网络配置的、终端保存在内部的信息。
实施本申请实施例可以通过第一载频的第一标识信息初步筛选与第一数据匹配的第一载频，进一步在筛选后的第一载频中根据第一载频信息及第一信道拥塞参数信息按照优先级顺序选择直连链路传输载频，使第一终端选择的传输载频尽量收敛，以使第二终端尽可能多的接收到第一终端发送的数据。
在一个具体的实施例中，假设基站为第一终端配置的第一载频包括F1、F2、F3、F4、F5、F6、F7、F8、F9等。其中，F1、F2、F3对应的数据业务优先级为1，F4、F5、F6对应的数据业务优先级为2，F7、F8、F9对应的数据业务优先级为3，如图7所示。此时第一终端获取的第一数据的业务优先级为2，那么第一终端可以初步筛选出的第一载频包括F4、F5、F6。进一步的，第一终端可以从F4、F5、F6中，选择至少一个直通链路传输载频。具体选择过程如下：
假设第一信道拥塞参数信息包括第一信道拥塞门限。
如图8所示，若F4对应的第一信道拥塞门限为50％，信道拥塞值为30％；F5对应的第一信道拥塞门限为60％，信道拥塞值为61％；F6对应的第一信道拥塞门限为40％，信道拥塞值为35％。
接下来从第一载频中选择第二载频。由于F5对应的信道拥塞值61％高于其第一信道拥塞门限60％，因此，F5不属于第二载频。故第二载频可以包括F6、F4，假设优先级顺序根据各个第一载频对应的信道拥塞值决定，则优先级顺序由高到低依次为F6、F4。第一终端可以从F6、F4中依次选择直连链路传输载频，在最终选定的直连链路传输载频向至少一个第二终端发送第一数据。若第一终端需要选择一个直连链路传输载频传输第一数据，直连链路传输载频则为F6；若第一终端需要选择两个直连链路传输载频传输第一数据，直连链路传输载频则为F6和F4。
在一个可能的实施例中，当第一终端满足第一条件时，方可执行上述实施例中的S103。即，在第一终端满足第一条件的情况下，第一终端根据第一载频信息、第一信道拥塞参数信息按照优先级顺序为第一数据选择至少一个直连链路传输载频。
可选地，第一条件包括第一终端在上述至少一个第一载频信息对应的载频上进行资源 选择或者资源重选。在一种可能的实施方式中，至少一个第一载频信息对应的载频可以是的当前选择的传输载频中的至少一个。在第三代移动伙伴计划定义的V2X协议R14版本中，第一终端从当前传输载频对应的资源集中选择资源可以采用侦听预留机制，每次进行资源选择或者资源重选要为以后的若干次传输预留资源。因此，当第一终端在进行资源选择或者资源重选的时候，表明前面若干次传输结束，此时终端可以进行载频选择或者重选，如果在每次传输都进行载频重选，开销太大。
可选地，第一条件包括上述第一配置信息发生变化。
具体地，若某个当前正在使用的载频的信道拥塞参数信息发生变化，导致该载频的信道拥塞值大于其对应的第一信道拥塞门限或者不属于第一信道拥塞范围时，则需要重新进行载频选择。
可选地，第一条件包括第一终端接收到基站发送的专用RRC信令。
示例性的，基站向第一终端发送专用RRC信令可以是资源重配置信令，此时，第一配置信息中包含的第一载频信息和/或第一信道拥塞参数信息可能发生了改变，或者是其它与载频选择相关的参数信息可能发生改变。可以理解的，第一配置信息从无到有也可以理解为发生变化。
可选地，第一条件包括第一终端接收到基站发送的SIB消息。
示例性的，基站向第一终端发送的SIB消息，SIB消息中第一配置信息中包含的第一载频信息和/或第一信道拥塞参数信息可能发生了改变，或者是其它与载频选择相关的参数信息可能发生改变。可以理解的，第一配置信息从无到有也可以理解为发生变化。
可选地，第一条件包括第一数据允许传输的载频不包括当前选择的传输载频。
示例性的，根据不同地区的频谱法规要求，不同的数据可能需要在不同的载频上进行传输。如果终端新获取的一个第一数据，如果当前已选择的传输载频中不包含允许该第一数据传输的载频，则此时需要为该第一数据在允许的载频范围内选择至少一个载频。可以理解的，首次进行传输时当前已选择的传输载频可以看作是空集。
可选地，第一条件包括第一载频信息对应的载频中存在至少一个第三载频，该第三载频的优先级顺序高于当前选择的传输载频中的至少一个载频的优先级顺序。
示例性的，当第一载频中存在至少一个第三载频，其优先级顺序高于当前选择的传输载频中的至少一个载频的优先级顺序，即满足资源重选的条件，第一终端可以选择该优先级顺序更高的第三载频作为直连链路传输载频。
可以知道的是，为了避免频繁的进行载频选择或载频重选，可以设置第一终端在一段时间内不可随意进行载频选择或载频重选。具体可以为，在一段时间内，若当前选择的载频的信道拥塞值满足条件，即使存在优先级更高的第三载频，也无需进行载频选择或载频重选，只有在一段时间之后，存在优先级更高的第三载频时方可进行载频选择或载频重选，将该优先级更高的第三载频作为直连链路传输载频。
可选地，第一条件包括第一载频信息对应的载频中存在至少一个第三载频，该第三载频对应的信道拥塞值小于当前选择的传输载频中的至少一个载频对应的信道拥塞值。
示例性的，若优先级顺序由各个第一载频对应的信道拥塞值决定，当第一载频中存在至少一个第三载频，其信道拥塞值小于当前选择的传输载频中的至少一个载频对应的信道 拥塞值，即满足载频选择或载频重选的条件，第一终端可以选择该优先级顺序更高的第三载频作为直连链路传输载频。
可以知道的是，为了避免频繁的进行载频选择或载频重选，可以设置第一终端在一段时间内不可随意进行载频选择或载频重选。具体设置可以参考上述将优先级顺序更高的第三载频作为传输载频的实施例中的相关描述，在此不再赘述。
进一步地，第一条件包括第一载频信息对应的载频中存在至少一个第三载频，第三载频对应的信道拥塞值小于当前选择的传输载频中的至少一个载频对应的信道拥塞值，且第三载频对应的信道拥塞值与当前选择的传输载频中的至少一个载频对应的信道拥塞值的差距值大于或者等于第一阈值。
可以知道的是，为了避免频繁的进行载频选择或载频重选，在第三载频对应的信道拥塞值小于当前选择的传输载频中的至少一个载频对应的信道拥塞值的情况下，还需该第三载频对应的信道拥塞值与当前选择的传输载频中的至少一个载频对应的信道拥塞值的差距值大于或者等于第一阈值，示例性的该第三载频对应的信道拥塞值与当前选择的传输载频中的至少一个载频对应的信道拥塞值的差距值也可以定义为第三载频对应的信道拥塞值减去当前选择的传输载频中的至少一个载频对应的信道拥塞值得到的差值的绝对值。例如，第一阈值可以是0.1，即还需要当前选择的传输载频中的至少一个载频对应的信道拥塞值与第三载频对应的信道拥塞值的差异值需要大于或者等于0.1。通过设置第一阈值可以确保将要重选的第三载频对应的信道拥塞值在一定程度上优于其将要替换的当前选择的传输载频，进而保证通信质量在第一程度上有所提高。
可选地，第一条件包括第一终端当前选择的传输载频中的至少一个载频对应的信道拥塞值小于或等于第二信道拥塞门限。
示例性的，当第一终端当前选择的传输载频中至少一个传输载频对应的信道拥塞值小于或者等于第二信道拥塞门限时，满足载频选择或载频重选的条件，第一终端可以直接从第一载频中选择至少一个直连链路传输载频。在一种可行的实施例中，第二信道门限可以是一个很小的值，当第一终端当前选择的传输载频中至少一个传输载频对应的信道拥塞值小于或者等于第二信道拥塞门限时，该传输载频的利用率不高，基站完全可以将第一终端调度在别的在载频上，从而减少发送链个数或者利用该传输载频来进行别的业务。。本发明不排除其它载频选择或者载频重选的目的。
可选地，第一条件包括第一终端当前选择的传输载频中的至少一个载频对应的信道拥塞值在第二信道拥塞范围内。
具体地，当第一终端当前选择的传输载频中至少一个传输载频对应的信道拥塞值在第二信道拥塞范围内时，满足载频选择或载频重选的条件，第一终端可以直接从第一载频中选择至少一个直连链路传输载频。
示例性的，第二信道拥塞范围可以是一个相对较大的值，当第一终端当前选择的传输载频中至少一个传输载频对应的信道拥塞值在第二信道拥塞范围内时表明当前选择的传输载频的拥塞程度较大，可能会影响通信质量。因此满足载频选择或载频重选的条件，第一终端可以直接从第一载频中选择至少一个直连链路传输载频。
或者，示例性的，第二信道拥塞范围可以是一个相对较小的值，当第一终端当前选择 的传输载频中至少一个传输载频对应的信道拥塞值在第二信道拥塞范围内时表明该传输载频的利用率不高，基站完全可以将第一终端调度在别的在载频上，从而减少发送链个数或者利用该传输载频来进行别的业务。因此满足载频选择或载频重选的条件，第一终端可以直接从第一载频中选择至少一个直连链路传输载频。本发明不排除其它载频选择或者载频重选的目的。
可选地，第一条件包括第一终端当前选择的传输载频中的至少一个载频对应的信道拥塞值大于或等于第三信道拥塞门限。
具体地，当第一终端当前选择的传输载频中至少一个载频对应的信道拥塞值大于或等于第三信道拥塞门限时，表明当前选择的传输载频的拥塞程度较大，可能会影响通信质量，因此满足载频选择或载频重选的条件，第一终端可以直接从第一载频中选择至少一个直连链路传输载频。可以知道的是，第三信道拥塞门限可以大于第一信道拥塞门限。
可选地，第一条件包括第一终端当前选择的传输载频中的至少一个载频对应的信道拥塞值不属于第三信道拥塞范围。
具体地，当第一终端当前选择的传输载频中至少一个载频对应的信道拥塞值不属于第三信道拥塞范围时，满足载频选择或者重选的条件，第一终端可以直接从第一载频中选择至少一个直连链路传输载频。可以知道的是，第三信道拥塞范围的大小可以包含整个第一信道拥塞范围，即第一信道拥塞范围处于第三信道拥塞范围之内。
可选地，第一条件包括载频选择或者载频重选计时器清零。
具体的，为了限制频繁的进行载频选择或者载频重选，可以为第一终端配置一个计时器。当发起载频选择或者载频重选，计时器从一个设定值T1开始减小，当计时器减小到零的时候，发起载频选择或者载频重选。
可选地，T1可以包含在基站发送的专用RRC信令或者SIB或者包含在预配置信息中。具体的，预配置信息可以是终端在出厂时预先配置在终端内部的信息，也可以是由网络配置的、终端保存在内部的信息。
可以知道的是，当前选择的传输载频对应的信道拥塞值包括当前选择的传输载频对应的第二资源集的信道拥塞值。在一个可能的实施例中，第二资源集可以是一个资源池，资源池中包含至少一个时频资源。在一个可能的实施例中，至少一个当前选择的传输载频对应的第二资源集是指至少一个当前选择的传输载频上的部分或者全部时频资源。具体的，第二资源集可以是连续的，可以是不连续的。第二资源集可以与第一资源集相同或者不同。
可以知道的是，当前选择的传输载频对应的信道拥塞值可以由第一终端测量得到，还可以由第一终端接收基站向其发送的专用RRC信令或SIB消息得到。
本申请实施例，提供了多种载频选择和载频重选的触发条件，在满足第一条件的情况下方可进行载频选择和载频重选，避免终端随意进行载频选择和载频重选，在保证终端选择的传输载频尽量收敛，接收端能尽可能的接收到更多的数据的情况下，兼顾接收端的复杂度，进一步提升通信质量。
