技术领域
本发明涉及通信技术领域，尤其是指一种资源确定方法及通信设备。
背景技术
Sidelink(直通链路或旁链路)终端可以在Sidelink上和其他终端进行通信，这些终端通常是支持Sidelink技术的车辆、路侧单元(Road Site Unit，RSU)、手机等。
用户在进行Sidelink传输(发送或者接收)时会基于选择的同步源(synchronization reference source)或又称为同步参考(synchronization reference)或又称为定时参考(timing reference)的定时来进行，用户的同步源可以是基站、全球卫星导航系统(Global Navigation Satellite System，GNSS)、自身本地时钟产生的定时或者其他设备提供的定时。Sidelink资源可能基于Sidelink定时进行编号，此时Sidelink的帧号称为直连帧号(Direct Frame Number，DFN)。可能存在以下场景：
一种场景是载波1上的控制节点调度用户在载波2上进行Sidelink传输，该用户在载波2上使用该控制节点的定时作为自己Sidelink传输的Sidelink定时。
另一种场景是工作在载波1上的控制节点调度用户在载波2上进行Sidelink传输，该用户在载波2上使用其他定时，例如GNSS的定时作为自己Sidelink传输的Sidelink定时。此时Uu定时和Sidelink定时可能不对齐。
此外，sidelink和Uu的子载波间隔(subcarrier spacing，SCS)也可能不同，因此定时精度也不相同。
为了提高Sidelink上数据传输的可靠度和资源利用率，在Sidelink技术 中也引入了混合自动重选请求(Hybrid Automatic Repeat reQuest，HARQ)反馈机制；Sidelink接收用户收到Sidelink数据(Sidelink数据在物理旁链路共享信道PSSCH上传输，其中PSSCH由旁链路控制信息SCI调度，SCI在物理旁链路控制信道PSCCH和/或PSSCH上传输)后可以通过反馈Sidelink HARQ-ACK信息来指示Sidelink的传输是成功还是失败，该Sidelink HARQ-ACK在物理旁链路反馈信道(Physical Sidelink Feedback Channel，PSFCH)资源上传输。
Sidelink数据包的传输可能是在控制节点和终端之间进行的(此时控制节点工作在sidelink)，也可能是在终端和终端之间的sidelink上进行的，对后者这种情况，控制节点可能无法直接知道该sidelink数据包的传输是否成功，需要由用户将Sidelink HARQ ACK信息(例如sidelink ACK/NACK)发送给控制节点，从而控制节点才可以进一步确定sidelink上的传输是否成功。将某个sidelink传输对应的Sidelink HARQ-ACK信息发给控制节点的终端是发送这个sidelink传输的发送终端。为了保证Sidelink HARQ-ACK信息的发送，控制节点需要为终端分配物理上行控制信道(Physical Uplink Control Channel，PUCCH)/物理上行共享信道(Physical Uplink Shared Channel，PUSCH)资源。
但是Sidelink定时和Uu定时可能不同，和/或，定时精度不同，用户理解的Sidelink传输资源/PSFCH/PUCCH/PUSCH资源位置和控制节点理解的Sidelink传输资源/PSFCH/PUCCH/PUSCH资源可能不同或可能存在模糊性。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
在本发明实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本发明实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
本发明实施例提供的资源确定方法既可以应用于终端也可以应用于控制节点；其中，终端可以为手机、平板电脑、笔记本电脑、超级移动个人计算机(Ultra-Mobile Personal Computer，UMPC)、上网本、可穿戴式设备(Wearable Device)、车载设备或者个人数字助理(Personal Digital Assistant，PDA)等。需要说明的是，在本发明实施例中并不限定终端的具体类型。控制节点指的是基站或者一些集成接入回程节点(Integrated Access Backhaul，IAB)，在sidelink中，控制节点可以是终端，路侧单元(Road Side Unit，RSU)，基站，也可能是一些类似RSU或者IAB的其他网络设施，因此一些控制节点可能同时具备sidelink和Uu链路；其中，基站可以为通常所用的基站，也可以为演进型基站(evolved node base station，eNB)，还可以为5G系统中的网络侧设备(例如下一代基站(next generation node base station，gNB)或发送和接收点(transmission and reception point，TRP))或者小区cell等设备。
需要说明的是，本发明实施提及的Uu传输、Uu SCS、Uu链路、Uu资源的含义是终端和基站之间上行传输和/或下行的传输、终端和基站之间上行SCS和/或下行SCS、终端和基站之间上行链路和/或下行链路、终端和基站之 间上行资源和/或下行资源等。
其中，控制节点对终端的调度包括：Inter-RAT sidelink调度和intra-RAT sidelink调度)；
例如，控制节点为LTE基站时，控制节点可以调度NR sidelink(此种情况称为：Inter-RAT sidelink调度)或者LTE sidelink(此种情况称为：intra-RAT sidelink调度)。控制节点为5G或者以后版本的基站时，控制节点可以调度NR sidelink(此种情况称为：intra-RAT sidelink调度)或者LTE sidelink(此种情况称为：Inter-RAT sidelink调度)。
如图1所示，本发明实施例提供一种资源确定方法，包括：
步骤101，根据时间间隔y 2和物理旁链路反馈信道PSFCH的第一时域位置T PSFCH_SL，或者，根据时间间隔y 2和PSFCH的第二时域位置T PSFCH_Uu，确定目标上行信道的时域资源；所述时间间隔y 2为PSFCH与目标上行信道之间的时间间隔；其中，所述目标上行信道的时域资源满足下述任意一项条件：
T PSFCH_SL+y 2的时间范围内第A个时域资源；
T PSFCH_Uu+y 2的时间范围内第A个时域资源；
和T PSFCH_SL+y 2重叠的第A个时域资源；
和T PSFCH_Uu+y 2重叠的第A个时域资源；
不早于T PSFCH_SL+y 2的第A个时域资源，或称为：不早于对应T PSFCH_SL+y 2的时域资源的第A个时域资源；
不早于T PSFCH_Uu+y 2的第A个时域资源，或称为：不早于对应T PSFCH_Uu+y 2的时域资源的第A个时域资源；
其中，A为大于或者等于1的整数。
本发明实施例中，若目标上行信道的时域资源为T PSFCH_SL+y 2的时间范围内第A个时域资源，或者，T PSFCH_SL+y 2重叠的第A个时域资源，或者，不早于T PSFCH_SL+y 2的第A个时域资源的情况下，终端和控制节点能够基于Sidelink定时实现对目标上行信道的时域资源的理解一致；
若目标上行信道的时域资源为T PSFCH_Uu+y 2的时间范围内第A个时域资源，或者，和T PSFCH_Uu+y 2重叠的第A个时域资源，或者，不早于T PSFCH_Uu+y 2的第A个时域资源的情况下，终端和控制节点能够基于Uu定时实现对目标 上行信道的时域资源的理解一致。
本步骤中，对于终端和控制节点而言，时间间隔y 2可以是预先约定的；对于终端来说，时间间隔y 2也可以是高层配置的，或者是基站通过下行控制信息DCI配置的，在此不做具体限定。目标上行信道包括：物理上行控制信道PUCCH或物理上行共享信道PUSCH。
可选的，上述第A个时域资源具体可以为：第A个时域资源，或者，第A个可用时域资源。例如，T PSFCH_SL+y 2的时间范围内第1(假设A＝1)个时域资源为：T PSFCH_SL+y 2的时间范围内的第1个时域资源，或者，T PSFCH_SL+y 2的时间范围内的第1个可用时域资源(若T PSFCH_SL+y 2的时间范围内的第1个时域资源不可用、第2个时域资源可用，则该T PSFCH_SL+y 2的时间范围内的第2个时域资源为上述第1个可用时域资源)。
例如T PSFCH_SL+y 2对应的15kHz时隙对应两个30kHz的时隙，第A＝1个时域资源则表示T PSFCH_SL+y 2对应的15kHz时隙内的第一个30kHz的时隙。
例如T PSFCH_SL+y 2对应的15kHz时隙对应两个30kHz的时隙，其中第一个时隙用于下行，第二个时隙用于上行，第A＝1个可用的时域资源则表示T PSFCH_SL+y 2对应的15kHz时隙内的第一个可用于上行30kHz的UL时隙。
需要说明的是，终端和控制节点根据下行控制信息DCI、PSCCH配置、PSSCH配置、PSFCH配置中的至少一个可以分别确定T PSFCH_Uu。可选的，T PSFCH_SL为PSFCH的接收或发送时间，例如，接收或发送PSFCH的Sidelink时隙的起点。
作为一种实现方式，上述时域资源可以为时隙，例如，不早于T PSFCH_Uu+y 2的第A个时隙，或者，不早于对应T PSFCH_Uu+y 2的Sidelink时隙的第A个时隙，或者，不早于对应T PSFCH_Uu+y 2的Uu时隙的第A个时隙。
可选地，上述不早于是指时域资源的起点不早于，例如，时隙的起点不早于。
可选的，所述目标上行信道用于传输旁链路Sidelink的混合自动重传请求应答HARQ-ACK信息。
例如，一个目标上行信道的资源可能关联一个或者多个(物理Sidelink反馈信道)PSFCH，终端将从其关联的PSFCH上获取的Sidelink的HARQ-ACK 信息经过一定的处理后在该目标上行信道上发送给控制节点。
其中，Uu链路的HARQ-ACK信息或其他反馈信息也可以复用在目标上行信道上，在此不做具体限定。
可选的，PSFCH的第一时域位置为基于Sidelink定时确定的PSFCH的时域位置；PSFCH的第二时域位置为基于Uu定时确定的PSFCH的时域位置。
需要说明是，Sidelink定时和Uu定时之间的时间偏移可以为0，也可以不为0。sidelink的子载波间隔(SubCarrier Spacing，SCS)和Uu的子载波间隔可能相同，也可能不同；因此定时精度可能相同也可能不相同。
作为一个可选实施例，在Sidelink定时和Uu定时之间存在定时偏移的情况下，所述方法还包括：
根据下行控制信息DCI的时域位置T DCI_Uu、DCI和所述DCI指示的Sidelink资源之间的时间间隔y 1、时间间隔gap、以及Sidelink定时和Uu定时之间的定时偏移offset中的至少一项，确定PSFCH的第一时域位置T PSFCH_SL；其中，时间间隔gap为Sidelink资源和所述Sidelink资源对应的PSFCH之间的时间间隔，或者时间间隔gap为Sidelink资源和所述目标上行信道对应的PSFCH之间的时间间隔。例如，T PSFCH_SL＝T DCI_Uu’+y 1+gap+offset。其中，T DCI_Uu’等于T DCI_Uu或T DCI_Uu所在时域资源的起点或终点。
换言之，第一时域位置T PSFCH_SL与下行控制信息DCI的时域位置T DCI_Uu、DCI和所述DCI指示的Sidelink资源之间的时间间隔y 1、时间间隔gap、以及Sidelink定时和Uu定时之间的定时偏移offset中的至少一项相关。
或者，在Sidelink定时和Uu定时之间存在定时偏移的情况下，所述方法还包括：根据PSFCH的第二时域位置T PSFCH_Uu以及Sidelink定时和Uu定时之间的定时偏移offset，确定PSFCH的第一时域位置T PSFCH_SL。例如，T PSFCH_SL＝T PSFCH_Uu+offset。
换言之，第一时域位置T PSFCH_SL与PSFCH的第二时域位置T PSFCH_Uu以及Sidelink定时和Uu定时之间的定时偏移offset相关。
其中，由于定时偏移的值可能为整数，也可能为非整数；在定时偏移的值为非整数的情况下，上述公式中offset的一种取值是对定时偏移向上取整 后对应的值，例如offset＝ceil(定时偏移)；另一个取值是对定时偏移向下取整后对应的值，例如offset＝floor(定时偏移)。具体的，在一种实现中，T DCI_Uu为终端接收到DCI的时间减去1/2TA(TA为时间提前的相关量，例如定时提前Timing Advance。
在一种实现中y 1为DCI和所述DCI指示的第一个Sidelink资源之间的时间间隔；另一种实现中，gap为第一个Sidelink资源和所述第一个Sidelink资源对应的PSFCH之间的时间间隔。另一种实现中gap为第一个Sidelink资源和所述目标上行信道对应的PSFCH之间的时间间隔。进一步可选地，gap可能是第一个sidelink资源和最后一个Sidelink资源对应的PSFCH之间的时间间隔。
具体地，假设一个DCI调度B个sidelink资源或者一个配置sidelink授权资源中包含B个sidelink资源，每个sidelink资源对应一个PSFCH时机，不同的sidelink资源对应的PSFCH时机可能为相同的PSFCH时机，但是也可能为不同的PSFCH时机，这些时机可能对应同一个目标上行信道。在一种实现中，gap为第一个Sidelink资源和第B个Sidelink资源对应的PSFCH时机之间的时间间隔。
需要说明的是，第一个Sidelink传输开始的时间不早于T DCI_Uu+y 1的第一个Sidelink时域资源(例如Sidelink时隙)。
作为一个可选实施例，在Sidelink定时和Uu定时之间不存在定时偏移(即定时偏移为0，或者，Sidelink定时和Uu定时对齐)的情况下，所述方法还包括：
根据下行控制信息DCI的时域位置T DCI_Uu、DCI和所述DCI指示的Sidelink资源之间的时间间隔y 1以及时间间隔gap中的至少一项，确定PSFCH的第一时域位置T PSFCH_SL；其中，时间间隔gap为Sidelink资源和所述Sidelink资源对应的PSFCH之间的时间间隔，或者时间间隔gap为Sidelink资源和所述目标上行信道对应的PSFCH之间的时间间隔；例如，T PSFCH_SL＝T DCI_Uu’+y 1+gap。其中，T DCI_Uu’等于T DCI_Uu或T DCI_Uu所在时域资源的起点或终点。
换言之，第一时域位置T PSFCH_SL与下行控制信息DCI的时域位置T DCI_Uu、 DCI和所述DCI指示的Sidelink资源之间的时间间隔y 1、以及时间间隔gap中的至少一项相关。
或者，在Sidelink定时和Uu定时之间不存在定时偏移(即定时偏移为0，或者，Sidelink定时和Uu定时对齐)的情况下，所述方法还包括：
根据PSFCH的第二时域位置T PSFCH_Uu，确定PSFCH的第一时域位置T PSFCH_SL；例如，T PSFCH_SL＝T PSFCH_Uu。
换言之，第一时域位置T PSFCH_SL与PSFCH的第二时域位置T PSFCH_Uu相关。
具体的，在一种实现中，T DCI_Uu为终端接收到DCI的时间减去1/2TA(TA为时间提前的相关量，例如定时提前Timing Advance。在一种实现中，第一个Sidelink传输开始的时间不早于T DCI_Uu+y 1的第一个Sidelink时域资源(例如Sidelink时隙)。
需要说明的是，上述T DCI_Uu所在时域资源的起点或终点中，时域资源的一种可能性是Uu时隙或Sidelink时隙；优选的，该时隙资源为Sidelink时隙。
可选的，y 1为DCI和所述DCI指示的第一个PSSCH和PSCCH资源之间的时间间隔；或者，y 1为DCI和所述DCI指示的第一个PSSCH资源之间的时间间隔；或者，y 1为DCI和所述DCI指示的第一个PSCCH资源之间的时间间隔。
具体的，y 1为DCI和DCI指示的第一Sidelink传输之间的时间间隔；或者，gap为第一个Sidelink传输和第一个Sidelink传输对应的PSFCH之间的时间间隔。另一种实现中gap为第一个Sidelink资源和所述目标上行信道对应的PSFCH之间的时间间隔。进一步可选地，gap可能是第一个sidelink资源和最后一个Sidelink资源对应的PSFCH之间的时间间隔。
具体地，假设一个DCI调度B个sidelink资源或者一个配置sidelink授权资源中包含B个sidelink资源，每个sidelink资源对应一个PSFCH时机，不同的sidelink资源对应的PSFCH时机可能为相同的PSFCH时机，但是也可能为不同的PSFCH时机，这些时机可能对应同一个目标上行信道。在一种实现中，gap为第一个Sidelink资源和第B个Sidelink资源对应的PSFCH时机之间的时间间隔。
作为另一个可选实施例，所述offset是根据Sidelink子载波间隔计算的， 或者，所述offset是根据上行链路子载波间隔计算的。优选的，所述offset是根据上行链路子载波间隔计算的。
作为又一个可选实施例，所述y 2是根据Sidelink子载波间隔计算的，或者，所述y 2是上行链路子载波间隔计算的。
作为另一个可选实施例，所述gap是根据Sidelink子载波间隔计算的，或者，所述gap是根据上行链路子载波间隔计算的。
可选的，对于某些特殊情况下，例如N个Sidelink传输都对应相同的PSFCH时域资源或者该目标上行信道前只有一个PSFCH时域资源可以和N个Sidelink传输对应，且调度或配置的Sidelink传输的个数为N时，所述方法还包括：
根据PSFCH的周期N和PSFCH和对应的物理旁链路共享信道PSSCH之间的间隔K，确定所述gap。即在控制节点调度的Sidelink传输的个数与PSFCH的周期相同的情况下，或者配置Sidelink传输的个数与PSFCH的周期相同的情况下，
gap＝K+N；
其中，在一种实现中，N为PSFCH的周期，K为PSFCH和对应的物理旁链路共享信道PSSCH之间的最小间隔(例如MinTimeGapPSFCH)。
需要说明的是，在一种实现中，K和N的粒度为逻辑时隙(例如Sidelink时隙)；y 2的粒度为物理时隙；因此K个Sidelink时隙之间的实际距离可能大于K时隙的时长，N个Sidelink时隙之间的实际距离是可能大于N时隙的时长的。
作为另一个可选实施例，所述第A个时域资源包括：第A个Sidelink时域资源，或者，第A个Uu时域资源。
其中，所述第A个Uu时域资源为第A个上行时域资源。
可选地，上行时域资源是可以用于上行资源内传输的资源。
例如，满足上述任意一项条件的第一个时隙为下行时隙，此时不能用于PUCCH传输，需要继续顺延到最近一个可用于上行传输的时隙。
需要说明的是，上述T PSFCH_SL、T PSFCH_Uu、y 2、T DCI_Uu’、T DCI_Uu、y 1、gap、offset、N、K等参量的子载波间隔可能相同或不同；或者，上述参量可能为逻 辑时间，或者，物理时间；因此本发明的上述实施例提及的公式的具体计算过程中可能需要转换SCS和/或统一转换为逻辑时间或物理时间，在此不做具体限制。
下面结合几个示例及附图对本发明实施例提供的资源确定方法进行描述。需要说明的，下述实例中主要以DCI或者高层配置的所有sidelink资源对应相同的PSFCH时机(occasion，或者时域资源)进行举例，当不同的资源对应不同的PSFCH时机时，实现方法类似，但是gap可能需要重新计算，例如计算为第一sidelink资源和目标上行信道对应的PSFCH时机的时间间隔，可选地，目标上行信道对应的PSFCH时机为最后一个sidelink资源对应的PSFCH时机。
进一步需要说明的是，图2-图7中，阴影部分为PSFCH。
示例一，Sidelink定时和Uu定时之间存在定时偏移offset。
假设offset＝0.5个Sidelink时隙＝0.5个UL时隙；DCI调度两个Sidelink传输且K＝N＝2；上行链路子载波间隔(UL SCS)＝Sidelink子载波间隔(Sidelink SCS)＝30kHz。
按照基站定时，y2＝2(30kHz时隙)对应的时隙为时隙1，而按照Sidelink定时y2＝2对应的时隙为时隙1’，如图2所示，可以看出时隙1和时隙1’的位置不同。终端实际上会认为PUCCH的发送不能早于时隙1’，由于PUCCH资源是Uu资源，因此实际用于sidelink的HARQ-ACK信息反馈的PUCCH资源应该是以下情况中的一种：
和时隙1’重叠且不早于时隙1’的可用Uu时隙或UL时隙；
或者说，不早于时隙1’的最近一个可用Uu时隙或UL时隙；
或者说，对应T PSFCH_Uu+2+ceil(0.5)＝T PSFCH_Uu+3对应的Uu时隙；
或者说，不早于T PSFCH_Uu+2+ceil(0.5)＝T PSFCH_Uu+3对应的Uu时隙的最近一个可用UL时隙。
例如，如图2所示的时隙2上的PUCCH资源。该示例中，假设T PSFCH_Uu是PSFCH所在时隙的起点，因此，T PSFCH_Uu+2对应图2中的时隙1，T PSFCH_Uu+3对应图2中的时隙2；当T PSFCH_Uu定义为PSFCH所在时隙的终点时，T PSFCH_Uu+2和T PSFCH_Uu+3对应的时隙会对应性调整，例如后移。
示例二，Sidelink定时和Uu定时之间存在定时偏移offset。
假设offset＝0.5Sidelink时隙＝0.25UL时隙；DCI调度两个Sidelink传输且K＝N＝2；上行链路子载波间隔(UL SCS)＝15kHz，Sidelink子载波间隔(Sidelink SCS)＝30kHz。
按照基站定时y2＝1(15kHz时隙)对应的时隙为时隙1，而按照Sidelink定时y2＝1对应的时隙为时隙1’，如图3所示，可以看出时隙1和时隙1’的位置不同。因此实际用于sidelink的HARQ-ACK信息反馈的PUCCH资源应该是以下情况中的一种：
和时隙1’重叠且不早于时隙1’的可用Uu时隙或UL时隙；
或者说，不早于时隙1’的最近一个可用Uu时隙或UL时隙；
或者说，对应T PSFCH_Uu+2+ceil(0.5)＝T PSFCH_Uu+3对应的sidelink时隙的最近一个可用Uu时隙或UL时隙，这里的2和0.5是分别指y 2和offset按照sidelink SCS换算后的时隙数；
或者说，对应T PSFCH_Uu+1+ceil(0.25)＝T PSFCH_Uu+2对应的Uu时隙或UL时隙；这里的1和0.5是分别指y 2和offset按照UL SCS换算后的时隙数；
或者说，对应T PSFCH_Uu+1+ceil(0.25)＝T PSFCH_Uu+2对应的Uu时隙的最近一个可用UL时隙，这里的1和0.25是分别指y 2和offset按照UL SCS换算后的时隙数；
或者说，T PSFCH_Uu+1+ceil(0.5)＝T PSFCH_Uu+1UL slot duration+1SL slot duration对应的Uu时隙或者UL时隙，这里的1指y 2按照UL SCS换算后的时隙数，0.5是指offset按照sidelink SCS换算后的时隙数；
或者说，T PSFCH_Uu+1+ceil(0.5)＝T PSFCH_Uu+1UL slot duration+1SL slot duration对应的Uu时隙的最近一个可用UL时隙，这里的1指y 2按照UL SCS换算后的时隙数，0.5是指offset按照sidelink SCS换算后的时隙数。
例如，如图3所示的时隙2上的PUCCH资源。该示例中，假设T PSFCH_Uu是PSFCH所在时隙的起点，因此，T PSFCH_Uu+1对应图3中时隙1对应的UL SCS的时隙；当T PSFCH_Uu+1定义为PSFCH所在时隙的终点时，T PSFCH_Uu+y 2 对应的时隙会对应性调整，例如后移。
示例三，Sidelink定时和Uu定时之间存在定时偏移offset。
假设offset＝0.75Sidelink时隙＝1.5UL时隙；DCI调度两个Sidelink传输且K＝N＝2；上行链路子载波间隔(UL SCS)＝30kHz，Sidelink子载波间隔(Sidelink SCS)＝15kHz。
按照基站定时y2＝4(30kHz)对应的时隙为时隙1，而按照Sidelink定时y2＝4对应的时隙为时隙1’，如图4所示，可以看出时隙1和时隙1’的位置不同。因此实际用于sidelink的HARQ-ACK信息反馈的PUCCH资源应该是以下情况中的一种：
和时隙1’重叠且不早于时隙1’的可用Uu时隙或UL时隙；
或者说，不早于时隙1’的最近一个可用Uu时隙或UL时隙；
或者说，对应T PSFCH_Uu+2+ceil(0.75)＝T PSFCH_Uu+3对应的时隙的最近可用Uu时隙或UL时隙，这里的2和0.75是分别指y 2和offset按照sidelink SCS换算后的时隙数；
或者说，对应T PSFCH_Uu+4+ceil(1.5)＝T PSFCH_Uu+6对应的可用Uu时隙或UL时隙；这里的4和1.5是分别指y 2和offset按照UL SCS换算后的时隙数；
或者说，对应T PSFCH_Uu+4+ceil(1.5)＝T PSFCH_Uu+6对应的Uu时隙的最近一个可用UL时隙，这里的4和1.5是分别指y 2和offset按照UL SCS换算后的时隙数；
或者说，T PSFCH_Uu+2+ceil(0.75)＝T PSFCH_Uu+1UL slot duration+1SL slot duration对应的Uu时隙或者UL时隙，这里的2指y 2按照UL SCS换算后的时隙数，0.75是指offset按照sidelink SCS换算后的时隙数；
或者说，T PSFCH_Uu+2+ceil(0.75)＝T PSFCH_Uu+1UL slot duration+1SL slot duration对应的Uu时隙的最近一个可用UL时隙，这里的2指y 2按照UL SCS换算后的时隙数，0.75是指offset按照sidelink SCS换算后的时隙数。
例如，如图4所示的时隙3上的PUCCH资源。再例如，如图4所示，以“Sidelink SCS”为精度，时隙3对应图4中的“+3”(A等于1)；以“UL  SCS”为精度，时隙3对应4中的“+6”(A等于1)和“+7”(A等于2)，则实际用于sidelink的HARQ-ACK信息反馈的PUCCH资源为图4中的“+3”、“+6”和“+7”中的任意一个。
换言之，A不等于1的情况，也可称为：不早于T PSFCH_Uu+y 2或T PSFCH_SL+y 2的时域范围内的内的第2个时域资源、第3个时域资源等。其中，T PSFCH_Uu+y 2或T PSFCH_SL+y 2的时域范围对应的SCS和“第2个时域资源、第3个时域资源”对应的SCS不同。
该示例中，假设T PSFCH_Uu是PSFCH所在时隙的起点，因此，T PSFCH_Uu+1对应图3中时隙1对应的UL SCS的时隙；当T PSFCH_Uu+1定义为PSFCH所在时隙的终点时，T PSFCH_Uu+y 2对应的时隙会对应性调整，例如后移。
示例四，Sidelink定时和Uu定时对齐，即定时偏移offset＝0。
假设DCI调度两个Sidelink传输且K＝N＝2，UL SCS＝30kHz,SL SCS＝30kHz。如图5所示，y 1＝1时隙；y 2＝1(30kHz)时隙，此时基站和控制节点对PUCCH资源的理解一致，即PUCCH资源为时隙1’。
假设DCI调度两个Sidelink传输且K＝N＝2，UL SCS＝15kHz,SL SCS＝30kHz。如图6所示，y 1＝2时隙；y 2＝1(15kHz)时隙，此时PUCCH资源为不早于时隙1’的最近一个可用Uu时隙或UL时隙。
假设DCI调度两个Sidelink传输且K＝N＝2，UL SCS＝30kHz,SL SCS＝15kHz。如图7所示，y 1＝1时隙；y 2＝4(30kHz)时隙，此时PUCCH资源为不早于时隙1’的最近一个可用Uu时隙或UL时隙。
综上，本发明实施例中终端和控制节点根据所述时间间隔y 2和所述PSFCH的第一时域位置确定目标上行信道的时域资源，或者，终端和控制节点根据所述时间间隔y 2和所述PSFCH的第二时域位置确定目标上行信道的时域资源，且确定目标上行信道的时域资源满足的条件，能够实现终端和控制节点对目标上行信道的时域资源的理解一致，从而保证控制节点对目标上行信道的资源分配的适当性，提升终端确定目标上行信道的资源的准确率。

需要说明的是，本发明实施例提供的通信设备是能够执行上述资源确定方法的通信设备，则上述资源确定方法的所有实施例均适用于该通信设备，且均能达到相同或相似的有益效果。
优选的，本发明实施例还提供一种通信设备，包括处理器，存储器，存储 在存储器上并可在所述处理器上运行的计算机程序，该计算机程序被处理器执行时实现上述资源确定方法实施例的各个过程，且能达到相同的技术效果，为避免重复，这里不再赘述。
本发明实施例还提供一种计算机可读存储介质，计算机可读存储介质上存储有计算机程序，该计算机程序被处理器执行时实现上述资源确定方法实施例的各个过程，且能达到相同的技术效果，为避免重复，这里不再赘述。其中，所述的计算机可读存储介质，如只读存储器(Read-Only Memory，ROM)、随机存取存储器(Random Access Memory，RAM)、磁碟或者光盘等。
如图9所示，本发明实施例还提供一种资源确定方法，包括：
步骤901，获取旁链路Sidelink定时、Uu定时以及定时偏移中的至少一项；其中，定时偏移为Sidelink定时和Uu定时之间时间偏移；
步骤902，根据所述Sidelink定时、所述Uu定时以及所述定时偏移中的至少一项，确定配置Sidelink授权资源(sidelink configured grant或configured sidelink grant)和/或所述配置Sidelink授权资源的混合自动重传请求HARQ进程。
其中，定时偏移为Uu定时和Sidelink定时之间的offset,该offset的精度可能是微秒us；符号；时隙slot；子帧subframe；毫秒ms；帧frame；秒second等中的至少一个，在公式中定时偏移offset可能需要转换为相应的单位，例如转化为us数目，符号数目，slot数目，subframe数目，ms数目，second数目，frame数目中的至少一个，不做限制。
本发明实施例提供至少三种确定配置Sidelink授权资源和/或所述配置Sidelink授权资源的混合自动重传请求HARQ进程的方式，分别包括：
方式一：基于Sidelink定时(例如直接帧号DFN)，确定配置Sidelink授权资源和/或所述配置Sidelink授权资源的混合自动重传请求HARQ进程。
方式二：基于Uu定时(例如系统帧号SFN)以及定时偏移，确定配置Sidelink授权资源和/或所述配置Sidelink授权资源的混合自动重传请求HARQ进程。
方式三：基于Uu定时(例如系统帧号SFN)，确定配置Sidelink授权资源和/或所述配置Sidelink授权资源的混合自动重传请求HARQ进程。
方式三，一种实现方式是，终端假设y 4足够大到处理完Sidelink传输/PSFCH收发/PUCCH/PUSCH进程涉及的步骤。另一种实现方式是，终端在配置Sidelink授权资源传输时需要提前TA/2或TA进行传输。又一个实现方式是，终端在配置Sidelink授权资源传输时，假设(assume)或者期望(expect)配置Sidelink授权资源所在时隙边界和最近一次收到的下行控制信息或同步信号块SSB或信道状态信息参考信号CSI-RS或其他下行信号所在的时隙的定时提前TA/2或TA后推出的时隙边界或子帧边界或帧边界对齐；需要说明的是，边界对齐不意味着重叠。
作为一个可选实施例，所述方法还包括：
根据下行控制信息DCI和DCI指示的Sidelink资源之间的间隔y 3或者配置Sidelink授权的偏移值y 3、物理旁链路反馈信道PSFCH和用于传输Sidelink的HARQ-ACK信息的信道之间的间隔y 4、配置Sidelink授权资源内数据资源和/或控制资源占据的时域范围S 1、PSFCH的周期N以及PSFCH和对应的物理旁链路共享信道PSSCH之间的间隔K中的至少一项，确定配置Sidelink授权资源的周期。可选的，K为PSFCH和对应的PSSCH之间的最小间隔。
例如，所述配置Sidelink授权资源的周期满足下述至少一个条件：
大于y 3+S 1+(N+K-1)；
等于y 3+S 1+(N+K-1)；
大于S 1+(N+K-1)+y 4；
等于S 1+(N+K-1)+y 4；
大于y 3+S 1+(N+K-1)+y 4；
等于y 3+S 1+(N+K-1)+y 4；
其中，y 3为下行控制信息DCI和DCI指示的Sidelink资源之间的间隔或者配置Sidelink授权的偏移值(例如，timeOffsetCGType1)，可选地，该值可能为0，此时上述公式中没有y 3；y 4为物理旁链路反馈信道PSFCH和用于传输Sidelink的HARQ-ACK信息的信道之间的间隔；S 1为配置Sidelink授权资源内数据资源和/或控制资源占据的时域范围；N为PSFCH的周期；K为PSFCH和对应的物理旁链路共享信道PSSCH之间的最小间隔。
可选的，S 1可能是DCI指示的，也可能是高层配置的，在此不做具体限 定。
例如一个周期内配置Sidelink授权资源内数据资源和控制资源分别位于sidelink时隙1，sidelink时隙9和sidelink时隙10，则S1对应10个sidelink时隙或者S1对应sidelink时隙1到sidelink时隙10对应的物理时间长度。
其中，周期大于或者等于y 3+S 1+(N+K-1)，可保证每个周期内的最后一个传输对应的PSFCH都在相应的周期内。周期大于或者等于S 1+(N+K-1)+y 4；周期大于或者等于y 3+S 1+(N+K-1)+y 4，可保证每个周期内最后一个传输对应的PUCCH或PSUCH都在相应的资源内。
可选的，对于配置Sidelink授权资源，y 4具体指每个周期内最后一个和sidelink传输关联的PSFCH和对应PUCCH或PUSCH之间的间隔。
例如，周期最小值＝3sidelink slots，此时定时偏移＝0，Sidelink控制信息指示的时域资源占据的时域范围＝1slot，N＝1，K＝2，y4＝0。
需要说明的是，上述y 3+S 1+(N+K-1)或S 1+(N+K-1)+y 4或y 3+S 1+(N+K-1)+y 4的参量的子载波间隔SCS可能相同或不同；其中，一种实现方式是，K和N为逻辑时隙(例如sidelink时隙)；而y 3和y 4是物理时隙；进一步的精度或者SCS也可能不同，因此上述公式可能需要转换SCS和/或统一转换为逻辑时间或物理时间，在此不做具体限制。
当周期按照物理时间定义时，如果配置Sidelink授权资源和非Sidelink的资源冲突，认为该冲突部分的配置Sidelink授权资源或者该周期内的配置Sidelink授权资源无效。
可选的，步骤902中确定配置Sidelink授权资源的HARQ进程，包括：
根据HARQ进程起始值和/或进程偏移值，确定配置Sidelink授权资源的HARQ进程；
和/或，
根据配置Sidelink授权资源的标识信息，确定与所述配置Sidelink授权资源的标识信息对应的配置Sidelink授权资源的HARQ进程。
综上，本发明实施例中终端和控制节点根据所述Sidelink定时、所述Uu定时以及所述定时偏移中的至少一项，确定配置Sidelink授权资源和/或所述配置Sidelink授权资源的混合自动重传请求HARQ进程，能够实现终端和控 制节点对配置Sidelink授权资源的理解一致，从而保证控制节点对配置Sidelink授权资源分配的适当性，提升终端确定配置Sidelink授权资源的准确率。
为了更清楚的描述本发明实施例提供的资源确定方法，下面结合两个示例进行详细说明。
示例五，基于DFN确定配置Sidelink授权资源。
假设一个配置Sidelink授权资源和nrofHARQ-Processes(HARQ进程数)个进程关联。S为配置Sidelink授权资源中一个PSSCH传输机会或PSCCH传输机会的起始符号在时隙中的编号(例如startSLsymbols)。

[(DFN start time×numberOfSlotsPerFrame×numberOfSymbolsPerSlot+slot start  time×numberOfSymbolsPerSlot+symbol start time)+N×periodicity]modulo(1024×numberOfSlotsPerFrame×numberOfSymbolsPerSlot)，for all N>＝0。
其中，DFN start time，slot start time，和symbol start time分别是PSCCH传输机会或PSSCH的传输机会的DFN，时隙和符号。可选地，分别是一个周期内第一个PSCCH传输机会或第一个PSSCH的传输机会的DFN，时隙和符号。

其中，CURRENT_symbol＝(DFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot+slot number in the frame×numberOfSymbolsPerSlot+symbol number in the slot)；
ID_offset为该配置sidelink授权资源对应的HARQ ID偏移或者最小HARQ ID。

示例六，基于SFN和定时偏移offset配置Sidelink授权资源。
假设一个配置Sidelink授权资源和nrofHARQ-Processes(HARQ进程数)个进程关联。定时偏移offset为Uu定时和Sidelink定时之间的偏移。
S为配置Sidelink授权资源中一个PSSCH传输机会或PSCCH传输机会的起始符号在时隙中的编号(例如startSLsymbols)。
对于configured grant Type 1，配置sidelink授权资源的存在于满足下列公式，例如起始符号满足下列公式：
[(SFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot)+(slot number in the frame×numberOfSymbolsPerSlot)+symbol number in the slot]+Offset＝(timeDomainOffset×numberOfSymbolsPerSlot+S+N×periodicity)modulo(1024×numberOfSlotsPerFrame×numberOfSymbolsPerSlot),for all N>＝0。
对于configured grant Type 2，配置sidelink授权资源的存在于满足下列公式，例如起始符号满足下列公式：
[(SFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot)+(slot number in the frame×numberOfSymbolsPerSlot)+symbol number in the slot]+Offset＝[(SFN start time×numberOfSlotsPerFrame×numberOfSymbolsPerSlot+slot start time×numberOfSymbolsPerSlot+symbol start time)+N×periodicity]modulo(1024×numberOfSlotsPerFrame×numberOfSymbolsPerSlot),for all N>＝0。
其中，SFN start time，slot start time，和symbol start time分别是PSCCH传输机会或PSSCH的传输机会的SFN，时隙和符号。可选地，分别是一个周期内第一个PSCCH传输机会或第一个PSSCH的传输机会的SFN，时隙和符号。

HARQ Process ID＝ID_offset+[floor(CURRENT_symbol/periodicity)]modulo nrofHARQ-Processes
其中，CURRENT_symbol＝(SFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot+slot number in the frame×numberOfSymbolsPerSlot+symbol number in the slot)+offset
ID_offset为该CG对应的HARQ ID偏移或者最小HARQ ID。
可选地，ID_offset和配置sidelink授权资源ID有对应关系。
可选地，该ID_offset可以为0.
