技术领域
本公开涉及通信技术领域，尤其涉及一种资源选择方法、装置及终端设备。
背景技术
版本16(Release16，Rel-16)NR-V2X Mode2资源分配机制中，用户设备(User Equipment，UE)资源选择过程如下：
A)UE根据自身感知结果，将预约在资源选择窗内且接收的直通链路共享信道(Physical Sidelink Shared Channel，PSSCH)的参考信号接收功率(Reference Signal Receiving Power，RSRP)大于RSRP门限值的资源从资源选择窗内排除；其中，RSRP门限是根据接收业务包的优先级和待发送业务包的优先级确定；
B)经过资源排除，判断可用资源的比例。如果可用资源的比例小于资源选择窗内资源总数的X％，将RSRP门限值提升3dB，重复步骤A)中资源排除过程，直到可用资源的比例大于或等于X％；
C)UE从可用资源中随机选择传输所需资源。
然而，上述资源分配机制中存在半双工、隐藏节点等问题；为了解决这些问题，业内人士提出采用用户设备间协作(Inter-UE Coordination)机制进行资源分配，针对Inter-UE Coordination机制，相关方案为：
基于请求信令触发协调信息发送，该请求信令包含：子信道信息、RSRP门限值和业务包的优先级信息；协调UE在接收到协调请求信息后，可以根据协调请求信息中的信息确定有效的协调信息。
当然，协调请求信息中还可以包括被协调UE已选的时频资源，协调UE 在解码协调请求信息后，根据自身的感知结果，即：从协调UE的角度判断被协调UE选择的资源是否合适，如果不合适，可以反馈1bit信息用于标识被协调UE选择的资源是否合适(假设“0”表示不合适，“1”表示合适)，如果被协调UE接收到“0”，则可以触发其进行资源重选。
然而，相关的方案还是存在由于隐藏节点、半双工问题，被协调UE所选择资源并不一定合适，从而导致协调UE不能正确解码、协调请求信息开销不确定导致协调请求信息的承载方式不确定，以及，协调信息开销过大和时效性差的问题。
发明内容
本公开实施例提供一种资源选择、装置及终端设备，解决了在资源分配机制中，协调信息开销大、协调信息的时效性差和协调请求信息承载方式不确定的问题。

第二方面，本公开实施例提供一种终端设备，包括：收发机、存储器、处理器及存储在存储器上并可在处理器上运行的计算机程序，所述处理器执行所述计算机程序时实现如第一方面所述的资源选择方法的步骤。
第三方面，本公开实施例提供一种资源选择装置，应用于V2X直通链路的被协调UE，包括：
发送模块，用于发送直通链路资源协调请求信息；
接收模块，用于接收协调UE的直通链路资源协调信息；

第四方面，本公开实施例提供一种计算机可读存储介质，其上存储有计算机程序，该计算机程序被处理器执行时实现如第一方面所述的资源选择方 法的步骤。
本公开的上述技术方案的有益效果是：
本公开的方案，V2X直通链路系统的被协调UE在进行资源选择时，首先发送直通链路资源协调请求信息，然后接收协调UE发送的直通链路资源协调信息，最后，根据该直通链路资源协调信息进行直通链路的资源选择。这样，一方面，使得直通链路资源协调请求信息的开销确定，以方便确定直通链路资源协调请求信息的承载方式，另一方面，使协调UE根据该直通链路资源协调请求信息确定的直通链路资源协调信息的时效性更好，避免不必要的直通链路资源协调信息的传输导致直通链路资源协调信息信令开销过大的问题。

资源协调的目标资源选择窗指示信息；
被协调UE业务包发送参数；
RSRP门限值指示信息；
协调信息发送参数指示信息；
协调UE的指示信息。
这里，需要说明的是，协调信息类型指示信息可以用于表示期望协调UE发送的直通链路资源协调信息中的协调指示资源的类型，该类型可以为：可用时域资源、可用时频资源、不可用时域资源或不可用时频资源等；协调信息反馈的最大时延的指示信息可以用于表示接收协调UE发送的直通链路资源协调信息的最晚时间，即：在协调信息反馈的最大时延之前接收到的直通链路资源协调信息为有效的，这样，可以更好的保证直通链路资源协调信息的时效性；资源协调的目标资源选择窗指示信息用于表示期望协调UE在该资源协调的目标资源选择窗内进行协调指示资源的选择；被协调UE业务包发送参数用于表示被协调UE发送业务包所用到的参数，通过在直通链路资源协调请求信令中设置该被协调UE业务包发送参数，可以实现协调UE根据该参数进行资源选择以剔除不符合要求的资源，减小直通链路资源协调信息 不必要的开销；RSRP门限值指示信息用于表示被协调UE期望协调UE在进行资源选择时RSRP门限值的调整要求；协调信息发送参数指示信息用于表示协调UE期望被协调UE发送直通链路资源协调信息的发送方式；协调UE的指示信息用于表示有效的协调UE，如可以为：协调UE列表，在该协调UE列表中的UE即为有效的协调UE。
作为一个可选实施例，被协调UE业务包发送参数包括以下至少一项：
被协调UE待发送业务包占用的子信道个数；
被协调UE待发送业务包的重传次数；
被协调UE待发送业务包的发送周期；
被协调UE待发送业务包当前的计数器Counter值；
被协调UE待发送业务包的优先级；
被协调UE的目标资源选择窗口参数。
这里，需要说明的是，协调UE可以根据该协调UE待发送业务包占用的子信道个数确定直通链路资源协调请求信息中可用资源或者不可用资源的粒度，从而减少直通链路资源协调请求信息开销，例如：被协调UE传输资源需要占用两个连续的子信道，协调UE感知到某个时隙上仅有一个子信道可用，则虽然该资源未被占用，但是该资源并不适用于该被协调UE，从而该资源不要包含在该直通链路资源协调信息中。
协调UE可以根据被协调UE待发送业务包的重传次数调整协调信息中可用资源或者不可用资源的比例。
被协调UE待发送业务包的发送周期和被协调UE待发送业务包当前的计数器Counter值可以用于判断直通链路资源协调信息中的资源指示窗的长度或者直通链路资源协调信息的发送周期和/或发送次数。
被协调UE待发送业务包的优先级，可以用于：如果协调信息信令中的资源为不建议使用的资源，则协调UE在确定可用资源时，可以将比该优先级高的UE占用的资源从候选资源中排除，即：这些资源占用信息会包含在该直通链路资源协调信息中，被协调UE在接收到该直通链路资源协调信息进行资源选择时，应该避免这些被高优先级UE占用的资源，从而确保高优先级的性能。
被协调UE的目标资源选择窗口参数用于表示被协调UE预定义的资源选择窗，也就是说，无论被协调UE何时接收到直通链路资源协调信息，被协调UE的资源选择窗都为资源协调的目标资源选择窗指示信息所指示的范围，因此，协调UE仅需要发送资源协调的目标资源选择窗指示信息指示的时间段的终止时间之前的资源。需要说明的是，目标资源选择窗指示信息指示的时间段的终止时间可以为剩余业务包传输时延预算(Remaining Packet Delay Budget，Remaining PDB)，即业务包的最晚发送时刻。
当然，本公开实施例的直通链路资源协调请求消息还可以包括被协调UE的已选资源，协调UE在解码协调请求信息后，根据自身的感知结果，即从协调UE的角度判断被协调UE选择的资源是否合适，如果不合适，可以反馈1bit(比特)信息用于标识被协调UE选择的资源是否合适(假设“0”表示不合适，“1”表示合适)；若被协调UE接收到“0”，则可以出发其进行资源重选。
作为一个可选实施例，该协调信息类型指示包括：
可用的时频资源；或者
可用的时域资源；或者
不可用的时频资源；或者
不可用的时域资源。
本可选实施例中，协调信息类型指示用于标识被协调UE期望协调UE发送的协调信息的类型。
再如图3所示，作为一个具体实例，被协调UE发送的协调请求信息中包含协调信息类型指示(期望的协调信息的类型)，分别通过1bit信息指示为“期望发送的协调信息为可用资源(建议使用的资源)还是不可用资源(不建议使用的资源)”，1bit信息指示“期望发送的协调信息为时域资源还是时频资源(时域+频域资源)”。比如：为了解决半双工的问题，与协调信息类型指示对应的比特应为“00”，表示“不建议使用的时域资源”，协调UE在接收到该协调请求信息后，进行感知，发现协调UE要在如图3所示的104slot(时隙)和105slot进行业务包的发送，由于半双工的影响而不能接收数据。因此协调信息信令中包含的时域资源为：104slot、105slot。被协调UE在接 收到该协调信息信令时，将对应slot上的资源从候选资源中排除，在选择传输资源时，不会选择对应slot上的资源。
作为一个可选实施例，该协调信息反馈的最大时延的指示信息为下述任一项：
时延门限值，用于指示接收所述直通链路资源协调信息相对于发送所述直通链路资源协调请求信息的最大时延；
第一偏移时间，用于指示发送所述直通链路资源协调请求信息的时间相对于待发送业务包到达被协调UE物理层的时间的偏移。
这里，需要说明的是，时延信息用于指示在该时延信息所对应的时刻之前接收到的协调信息信令为有效协调信息信令，从而保证协调信息信令的时效性。也就是说，该时延信息为用于指示接收协调信息信令的最晚时间。
下面结合图4具体说明该时延信息，如图4所示，在n时刻触发协调请求信息，由高层配置的接收协调信息的最大时延为T maxdelay。如果在m1(m1<＝n+T maxdelay)时刻接收到该协调信息信令，则认为该协调信息信令是有效的；如果在m2(m2>n+T maxdelay)时刻接收到该协调信息信令，则认为该协调信息是无效的。
具体的，该时延信息可以为由高层配置的数值，如前述的时延门限值，该值为接收该协调信息信令相对于发送该协调请求信息的最大时延，也就是说，在发送该协调请求信息的时刻之后的时延门限值之内接收该协调信息信令为有效信令；即：协调UE能够根据发送该协调请求信息的时刻和该时延门限值确定发送该协调信息信令的最晚时间。
当然，该时延信息可以为绝对时间，如：接收该协调信息信令的最晚时间；也就是说，协调请求信息中可以包含指示接收该协调信息信令的最晚绝对时间。
该时延信息也可以为相对时间，如：第一偏移时间，用于指示发送该协调请求信息的时间相对于待发送业务包到达该协调UE物理层时间的偏移。
需要说明的是，在该时延信息为第一偏移时间的情况下，协调UE可以根据该协调请求信息的发送时刻与该第一偏移时间，确定待发送业务包到达该被协调UE的物理层的时刻，从而可以进一步根据该协调请求信息中携带 的该待发送业务包的优先级隐式地获得被协调UE接收该协调信息信令的最大时延(相对于待发送业务包到达的时刻或者相对于发送协调请求信息的时刻)。
作为一个可选实施例，该资源协调的目标资源选择窗指示信息包括下述任一项：
该被协调UE的目标资源选择窗的起始时间和终止时间；
该被协调UE的目标资源选择窗的终止时间。
需要说明的是，本可选实施例中，通过在该直通链路资源协调请求信息中设置该资源协调的目标资源选择窗指示信息，实现了对直通链路资源协调信息的时间上的限制，使得协调UE选择的协调指示资源至少位于资源协调的目标资源选择窗终止时间之前，从而降低直通链路资源协调信息的开销，保证直通链路资源协调信息更具有针对性。
具体的，该资源协调的目标资源选择窗指示信息可以显示地指示为目标资源选择窗起始时间的最晚时间和终止时间的最晚时间；如图2所示，该资源选择窗起始时间的最晚时间可以为m1+T maxdelay+处理时延，其中，m1表示发送该直通链路资源协调请求信令的时间，T maxdelay表示该直通链路资源协调请求信息中的协调信息反馈的最大时延的指示信息。
该资源选择窗参数可以为资源选择窗终止时间的最晚时间和资源选择窗长度T length，协调UE可以根据该资源选择窗终止时间的最晚时间和该资源选择窗长度获得该资源选择窗起始时间的最晚时间(资源选择窗终止时间的最晚时间-T length)。
该资源选择窗参数还可以为资源选择窗起始时间的最晚时间和资源选择窗长度T length，协调UE可以根据该资源选择窗起始时间的最晚时间和资源选择窗长度T length获得该资源选择窗终止时间的最晚时间(资源选择窗起始时间的最晚时间+T length)。
当然，该资源协调的目标资源选择窗指示信息还可以仅包括目标资源选择窗的终止时间，这种情况下，协调UE可以确定被协调UE所需要的资源为该终止时间之前的资源，这样，协调UE可以根据预配置规则自动确定资源指示窗的起始时间，以确定资源指示窗，并在确定的资源指示窗内确定有效 的协调信息。
当然，该资源协调的目标资源选择窗指示信息还可以为目标资源选择窗起始时间的最晚时间，这样，协调UE可以根据第一预配置的值确定资源指示窗终止的最晚时间(资源选择窗起始时间的最晚时间+第一预配置的值)；
当然，该资源协调的目标资源选择窗指示信息还可以仅为目标资源选择窗起始时间，这样，协调UE可以根据第二预配置的值确定资源指示窗的终止时间(资源选择窗起始时间+第二预配置的值)。
该资源协调的目标资源选择窗指示信息还可以为第二偏移时间，用于指示目标资源选择窗起始的最晚时间相对于发送该直通链路资源协调请求信息时间的偏移；这样，协调UE可以根据发送该直通链路资源协调请求信息的时间和该第二偏移时间得到资源指示窗起始时间的最晚时间(发送该直通链路资源协调请求信息的时间+第二偏移时间)，然后，根据预配置的值确定资源指示窗终止时间的最晚时间(发送该协调请求信息的时间+第二偏移时间+预配置的值)；
该资源协调的目标资源选择窗指示信息还可以为发送待发送业务包时间的最晚时间。
作为一个可选实施例，在该资源协调的目标资源选择窗指示信息仅包括该被协调UE的目标资源选择窗的终止时间的情况下，接收到的该直通链路的协调信息包括该协调UE感知的资源选择窗的起始时间。
也就是说，若被协调UE仅指示了目标资源选择窗的终止时间的话，协调UE确认被协调UE想要的协调信息为该时刻之前的资源占用信息，则协调UE可以根据自身的感知确定起始时间，并在发送直通链路协调信息时，将感知的起始时间发送给被协调UE，以使被协调UE能够获知该起始时间。
作为一个可选实施例，根据直通链路资源协调信息进行直通链路的资源选择，包括：
确定被协调UE的资源选择窗，其中被协调UE的资源选择窗为直通链路资源协调信息中包含的资源指示窗的至少部分；
在所述被协调UE的资源选择窗内进行直通链路的资源选择。
这里，需要说明的是，若直通链路资源协调请求信息中的资源协调的目 标资源选择窗指示信息包括起始时间和终止时间，如：[k1，k2]，则协调UE会反馈[k1，k2]时间段内的协调信息，被协调UE在确定资源选择窗的时候，可以选择资源选择窗的时间段为[k1，k2]，或者，为[k1，k2]中的一个子集。若直通链路资源协调请求信息中的资源协调的目标资源选择窗指示信息包括终止时间，则协调UE会将其自身感知的起始时间发送给被协调UE，以使被协调UE根据协调UE感知的起始时间和该目标资源选择窗指示信息所包括的终止时间，确定该资源选择窗；具体的，该资源选择窗可以为由以该协调UE感知的起始时间和该目标资源选择窗指示信息包括的终止时间所确定的窗口的部分或全部。
在该被协调UE的资源选择窗内进行直通链路的资源选择具体可以为：
被协调UE根据自身的感知结果确定上述资源选择窗的资源占用情况。确定可用资源集合SA；
根据反馈的直通链路资源协调信息确定最新的可用资源SA’，分为以下几种情况：
若协调信息中包含的是不可用的时域资源信息：对应不可用时域上的所有资源若在SA中，将对应的资源从SA中排除，经过排除后的集合为SA’；
若协调信息包含的是不可用的时频资源信息：若不可用时频资源在SA中，需要将其从SA中排除，经过排出后的集合为SA’；
若协调信息中包含的是可用的时频资源信息：SA’为SA和协调信息中包含的可用时频资源信息的交集或者并集；
若协调信息中包含的是可用的时域资源信息：SA’为SA和协调信息中包含的可用时域上的所有资源的交集或者并集。
从根据自身感知信息和协调信息得到的可用资源集合SA’中随机选择传输所需的资源。
作为一个可选实施例，该协调信息发送参数指示信息包括下述任一项：
发送周期；
发送周期和发送次数。
这里，需要说明的是，该协调信息发送参数指示信息可以为被协调UE期望协调UE发送该直通链路资源协调信息的发送方式，如：周期性发送； 当然，若为周期性发送的情况下，还可以进一步指示周期性发送的发送次数。当然，若被协调UE不期望协调UE周期性发送该直通链路协调信息的情况下，该直通链路资源协调请求信息中可以不包含该协调信息信令发送参数，或者，该协调信息发送参数指示信息为空。
作为一个可选实施例，该协调信息发送参数指示信息由高层配置或预配置；
或者，
在该被协调UE的业务为周期性业务的情况下，该发送周期为该被协调UE的业务周期，所述发送次数为所述被协调UE当前的计数器counter值。
也就是说，该协调信息信令发送参数可以由被协调UE的物理层从高层获得，或者，预先配置；或者，由被协调UE的周期性业务确定。
这里，需要说明的是，counter值为基于新空口的车用无线通信技术模式2(New Radio-Vehicle to everything mode2，NR-V2X mode2)资源分配中周期性业务持续占用某种资源的次数，当counter值为0时，可能触发被协调UE进行资源重选。
具体的，若发送直通链路资源协调请求信息的被协调UE为周期性业务，业务周期为100ms，当前的计数器counter值为10，该被协调UE在发送协调请求信息时，将协调信息信令发送参数标识为直通链路资源协调信息信发送周期为100ms，协调信息信令发送次数为10。协调UE在成功解码请求信息时，协调UE按如图5所示的，以周期100ms连续发送10次协调信息信令。
作为一个可选实施例，该RSRP门限值指示信息包括下述任一项：
RSRP门限值的最大值；
RSRP门限值调整次数的最大值。
需要说明的是，该RSRP门限值配置信息可以由高层配置。
具体的，该RSRP门限值指示信息可以用于协调UE在进行资源排除确定协调信息的过程中，协调UE根据该RSRP门限值指示信息对RPRP门限值进行调整，以使得判断出的可用资源比例大于或等于资源选择窗内资源总数的预设比例。其中，对该RSRP门限值的调整后的最终RSRP门限值不应大于该RSRP门限值的最大值，或者，调整该RSRP门限值的次数不应多于 该RSRP门限值调整次数的最大值。
另外，该直通链路资源协调请求信息还可包括被协调UE待发送业务包优先级，这样，协调UE可以根据该待发送业务包的优先级确定被协调UE期望的该RSRP门限值，具体可以为，通过预配置的RSRP门限值-业务包优先级对应关系，获得与该待发送业务包的优先级对应的RSRP门限值，也就是说，可以通过待发送业务包的优先级隐式地确定该RSRP门限值。
这里，以在该协调请求信息中包括协调信息类型指示信息、协调信息反馈的最大时延的指示信息、RSRP门限值指示信息，被协调UE业务包发送参数包括被协调UE待发送业务包占用的子信道个数的情况为例，说明被协调UE与协调UE之间的协作过程：
Step1：被协调UE在n时刻发送协调请求信息，其中包含子信道个数信息，如：待发送的业务包占用两个子信道、RSRP门限值、协调信息类型指示为‘11’(表示建议使用的时频资源信息)、接收协调信息的最大时延为3ms。
Step 2：在不考虑传输时延的情况下，协调UE在n时刻接收到该协调请求信息。根据该协调请求信息中的RSRP门限值排除资源选择窗内被占用的资源，确定所有可用资源。根据子信道个数信息，将仅有一个连续子信道未被占用的可用资源排除，从而确定所有适合于被协调UE使用的“可用”资源信息。
Step3：协调UE在n+1ms发送直通链路资源协调信息，在不考虑传输时延的情况下，被协调UE在n+1ms接收到该协调信息信令。
作为一个可选实施例，步骤101，发送直通链路资源协调请求信息，包括：
确定该直通链路资源协调请求信息发送的最大时延，所述直通链路资源协调请求信息发送的最大时延通过高层配置或者预配置，或者，根据确定的接收所述直通链路资源协调信息相对于待发送业务包到达所述被协调UE的物理层的时间的最大时延确定；
在确定的所述直通链路资源协调请求信息发送的最大时延内发送所述直通链路资源协调请求信息。
这里，需要说明的是，协调请求信息为由被协调UE的高层向物理层发 送的，因此，本步骤中，该协调请求信息到达该被协调UE的物理层可以是指被协调UE的高层向物理层发送的协调请求信息到达该物理层的时间。也就是说，被协调UE的物理层需要在接收到高层发送的协调请求信息的时刻起的预设时延内将该协调请求信息发送给协调UE。这样，能够确保协调请求信息的时间不会太晚，从而避免接收到的协调信息信令的时间不会超过最大时延，保证了协调信息信令的时效性，最终避免接收到的协调信息信令无效。
具体的，被协调UE在为该协调请求信息进行资源选择时，定义预设时延，表示资源选择窗终止时间相对于协调请求信息到达时刻的最大值。如图6所示，被协调UE在为协调请求信息进行资源选择时，资源选择窗中的T2<＝预设时延，T2具体取值取决于被协调UE的具体实现。被协调UE根据感知结果，在如图6所示资源选择窗内随机选择发送该协调请求信息所需的资源。其中，需要说明的是，图6的资源选择窗内的“方框”即为选择的用于传输该协调请求信息的资源。
作为一个可选实施例，该直通链路资源协调请求信息的优先级为下述任一项：
待发送业务包的优先级；
高层配置或者预配置的优先级；
预设优先级，所述预设优先级为第一差值与0中较大的一个，其中，所述第一差值为待发送业务包的优先级与预设值的差值，所述预设值由高层配置。
需要说明的是，根据目前第一阶段直通链路控制信息(1st-stage Sidelink Control Information，1st-stage SCI)的设计，1st-stage SCI中可以用3bit用于表示优先级信息，该优先级信息可以理解为该协调请求信息的优先级信息；则可以根据上述待发送业务包的优先级、高层配置的优先级、预配置的优先级、和预设优先级中的一个，写入1st-stage SCI中的优先级信息。
具体的，待发送业务包优先级即为：当前到达被协调UE物理层的等待发送的业务包的优先级，高层配置的优先级即为：被协调UE的物理层接收到的高层下发的该协调请求信息的优先级；预设优先级即为：根据待发送业务包与高层配置的预设值的第一差值与0的比较确定的优先级，其中，需要 说明的是，在本可选实施例中，“0”所表示的优先级为最高优先级，通过将该第一差值与“0”进行比较，是为了避免该第一差值为负数等不满足预设规则的情况发生。换句话说，该预设优先级即为确保该协调请求信息的优先级比该待发送业务包的优先级高预设值。预配置的优先级可以为最高优先级。
作为一个可选实施例，该直通链路资源协调请求信息承载于下述任一项：
第二阶段直通链路控制信息2nd-stage SCI；
无线资源控制(Radio Resource Control，RRC)信令；
链路接入控制层控制单元(Media Access Control Control Unit，MAC CE)。
也就是说，本可选实施例中，该协调请求信息可以承载于2nd-stage SCI、RRC信令或MAC CE。
作为一个可选实施例，在2nd-stage SCI承载该协调请求信息的情况下：
第一阶段直通链路控制信息1st-stage SCI中用于指示该2nd-stage SCI的格式的比特位为“10”或“11”。
具体的，1st-stage SCI中有2bit信息用来指示2nd-stage SCI的格式(format)，目前“00”和“01”分别用来表示相关的“SCI format-A”和“SCI format-B”，因此，本可选实施例可以定义新的2nd-stage SCI format用来传输该协调请求信息。其中，根据目前1st-stage SCI的设计，有2bit用来表示2nd-stage SCI的格式，因此，可以使用“10”或“11”来表示用于承载该协调请求信息的新的2nd-stage SCI格式。
作为一个可选实施例，该协调UE的指示信息可以包含一个或者多个目标协调UE的标识信息。
其中，若以广播或组播的方式发送该直通链路资源协调请求信息的情况下，该协调UE的指示信息包含一个或多个目标协调UE的ID；若已单播的方式发送该直通链路资源协调请求信息的情况下，该协调UE的指示信息可以为空。
由于以广播或组播的方式发送该协调请求信息时，接收该协调请求信息的UE为多个，为了在其他UE在接收到该协调请求信息后能够确定自身是否为有效的UE，本可选实施例中，在以广播或组播的方式发送该协调请求信息的情况下，该协调请求信息中包括该协调UE列表，以使得其他UE在接收到 该协调请求信息后首先判断自身是否在该协调UE列表中，从而判断自身是否为有效的协调UE，若为有效的协调UE，则可以进一步向被协调UE发送协调信息信令。
需要说明的是，本可选实施例中，一方面，该协调UE的指示信息可以由高层配置；另一方面，该协调UE的指示信息包含的UE为被协调UE期望的协调UE的列表，即为：被协调UE期望建立UE间协作的UE的列表。
下面，结合图7具体实例对UE间协作机制的交互流程进行说明：
Step 1：确定直通链路资源协调请求信息的内容：
直通链路资源协调请求信息中包括以下内容：
被协调UE发送参数，包括占用子信道个数为2、RSRP门限值为-75dBm；
期望反馈的协调信息的类型为可用时频资源；
协调信息目前窗口的终止时间为m1；
协调信息反馈的最大时延为3ms；
Step 2：根据预定义的时延(1ms)发送协调请求信息；
如图7所示，在n2时刻，直通链路资源协调请求信息到达物理层，然后根据感知结果为直通链路资源协调请求信息选择传输的资源。由于时延为1ms，所以选择的资源不能超过n2+1。如图7所示，最终选择的资源所处时刻为n2+1。
Step 3：协调UE接收到直通链路资源协调请求信息后，确定协调信息；
如图7所示，不考虑传输时延，协调UE在n2+1时刻接收到直通链路资源协调请求信息。考虑到处理时延(假设为1ms)，如图7所示，协调UE包含的协调信息的最早时间为n2+2，根据感知结果和直通链路资源协调请求信息中的RSRP门限值确定的可用的时频资源为#1、#2、#3、#4、#6(这些资源都是占用两个子信道)。由于请求信令包含的协调信息目标资源选择窗口仅包含终止时间为m1，所以可用资源#6不需要包含在协调信息中。除了可用资源信息还需要包含协调信息窗口的起始时间n2+2。
Step 3：发送协调信息。
由于直通链路资源协调请求信息中包含协调信息反馈的最大时延为3ms，所以发送直通链路资源协调信息的时间不能超过n2+3。如图7所示，不考虑 传输时延，发送协调信息的时间为n2+2。
Step 4：协调UE确定资源选择窗、资源选择窗以及进行资源排除和资源选择；
协调UE根据接收到的协调信息中起始时间为n2+2，确定的资源选择窗为[n2+3,m1]。然后根据自身的感知结果确定资源#1、#2、#3、#4、#5(这些资源都是占用两个子信道)为可用资源。取协调信息和自身信息感知的可用时频资源的交集，最终确定#1、#2、#3、#4为可用资源。然后从可用资源中随机选择传输所需资源。
本公开实施例的资源选择方法，通过对该协调请求信息的内容进行设计，使得协调请求信息的内容更加完善，避免了目前被协调UE自身感知的可用资源由于隐藏节点、半双工问题而不合适，使得接收UE不能对接收到的业务包正确解码，协调请求信息开销大，使得协调请求信息的承载方式不确定的问题；另外，协调UE根据该协调请求信息中的内容进行资源选择，实现了对协调信息时间上的限制，避免了不必要的协调信息的传输，降低了协调信息的开销且提高了协调信息的时效性。
如图8所示，本公开实施例还提供一种资源选择装置，应用于V2X直通链路的被协调UE，包括：
发送模块801，用于发送直通链路资源协调请求信息；
接收模块802，用于接收协调UE的直通链路资源协调信息；
选择模块803，用于根据所述直通链路资源协调信息进行直通链路的资源选择。
本公开的方案，V2X直通链路系统的被协调UE在进行资源选择时，首先发送模块801发送直通链路资源协调请求信息，然后接收模块802接收协调UE发送的直通链路资源协调信息，最后，选择模块803根据该直通链路资源协调信息进行直通链路的资源选择。这样，一方面，使得直通链路资源协调请求信息的开销确定，以方便确定直通链路资源协调请求信息的承载方式，另一方面，使协调UE根据该直通链路资源协调请求信息确定的直通链路资源协调信息的时效性更好，避免不必要的直通链路资源协调信息的传输导致直通链路资源协调信息信令开销过大的问题。
本公开实施例的资源选择装置中，直通链路资源协调请求信息包括以下至少一项：

在确定的直通链路资源协调请求信息发送的最大时延内发送直通链路资源协调请求信息。
本公开实施例的资源选择装置中，直通链路资源协调请求信息的优先级为下述任一项：
待发送业务包的优先级；
高层配置或者预配置的优先级；
预设优先级，预设优先级为第一差值与0中较大的一个，其中，第一差值为待发送业务包的优先级与预设值的差值，预设值由高层配置。

第二阶段直通链路控制信息2nd-stage SCI；

本公开实施例的资源选择装置中，协调UE的指示信息可以包含一个或者多个目标协调UE的标识信息。
本公开实施例的资源选择装置，通过对发送模块801发送的该直通链路资源协调请求信息的内容进行设计，使得协调请求信息的内容更加完善，避免了目前被协调UE自身感知的可用资源由于隐藏节点、半双工问题而不合适，使得协调UE不能正确解码，协调请求信息开销大，使得协调请求信息的承载方式不确定的问题；另外，协调UE根据该协调请求信息中的内容进行资源选择，实现了对协调信息时间上的限制，避免了不必要的协调信息的传输，降低了协调信息的开销且提高了协调信息的时效性。
