图1示出了根据实施例的可以发生直通链路通信的示例性无线通信系统。如图1所示，无线通信系统100包括基站110以及终端设备120-1和120-2。在本公开中，也可以将终端设备统称为终端设备120。基站110和终端设备120-1可以被配置为通过无线链路彼此耦接。具体地，基站110和终端设备120-1可以经由下行链路155和上行链路165进行信令和数据传输。终端设备120-1和终端设备120-2可以被配置为通过无线链路彼此耦接。具体地，终端设备120-1可以经由直通链路175向终端设备120-2进行信令和数据传输。经由直通链路175，终端设备120-1可以自主发起到终端设备120-2的传输，或者可以将来自基站110的传输中继到终端设备120-2。直通链路175可以支持从终端设备120-1到终端设备120-2的传输。在该意义上，终端设备120-1和终端设备120-2可以分别称为发送终端设备和接收终端设备。
可选地，基站110和终端设备120-2之间也可以设置有上下行链路(如图1中虚线所示)，以便于在二者之间进行信令和数据传输。可选地，终端设备120-2可以位于基站110的覆盖范围之外(未示出)，仅经由直通链路175与终端设备120-1通信。

在实施例中，电子设备250的收发单元254可以被配置为向发送终端设备120-1发送资源授权消息。收发单元254还可以被配置为接收来自发送终端设备120-1的资源选择信息，该资源选择信息可以指示第一分配模式所对应的时频资源是否被发送终端设备120-1选择使用。未被选择使用的时频资源可以由资源管理单元252另行分配。
在实施例中，电子设备200和250可以以芯片级来实现，或者可以通过包括其他部件(例如图中以虚线示出的无线电部件)以设备级来实现。例如，各电子设备可以作为整机形式的通信设备工作。

如图3所示，在发送终端设备120-1与基站110建立连接后，在302处，基站110 通过无线电资源控制(Radio Resource Control,RRC)信令(例如RRC重配置信息)向发送终端设备120-1发送不同资源分配模式的参数配置信息。例如，参数配置信息可以包括基站110预先配置的不同分配模式所对应的资源池信息以及直通链路通信的初始化信息(例如，直通链路通信的频率、Pcell信息等)。在一个实施例中，基站110可以通过广播消息(例如在NR系统的SIB21中)向第一终端设备发送多种分配模式的参数配置信息。例如，可以通过广播消息发送多种分配模式所对应的资源池信息和直通链路通信的初始化信息中的至少部分信息。
在304处，在接收到多种分配模式的参数配置信息后，终端设备120-1通过多种分配模式查找时频资源以获得候选资源集合，该候选资源集合可以包括通过多种分配模式查找到的时频资源。终端设备120-1进一步从候选资源集合中选择时频资源，用于进行到接收终端设备120-2的直通链路通信。由于候选资源集合包括通过多种分配模式查找到的时频资源，终端设备120-1可以选择更好地满足直通链路的QoS需求的时频资源。所选择的时频资源可以包括与第一分配模式对应的时频资源和/或与第二分配模式对应的时频资源。
在306处，在选择了时频资源后，终端设备120-1向终端设备120-2通知所选择的时频资源，用于进行到终端设备120-2的直通链路通信。例如，可以通过直通链路控制信息传送具体时频资源信息或索引来向终端设备120-2通知所选择的时频资源。在308处，终端设备120-1还向基站110发送资源选择信息，该资源选择信息指示资源选择情况，例如特定资源是否被选择。
在310处，终端设备120-1通过所选择的时频资源经由直通链路进行到终端设备120-2的通信。例如，在NR系统中，可以通过物理直通链路共享信道(PysicalSidelink Share Channel,PSSCH)进行通信。
通过多种分配模式获得候选资源集合
本公开涉及针对直通链路通信的多种资源分配模式。第一分配模式可以包括由基站调度并向发送终端设备授权时频资源。例如，调度可以基于发送终端设备的资源调度请求。
第二分配模式可以包括由发送终端设备感知并查找时频资源。图4示出了根据实 施例的第二分配模式的示例操作。如图4所示，操作400包括在402处确立资源窗。该资源窗可以为一定持续时间的时间窗。操作400包括在404处在资源窗中进行资源感知。终端设备可以对预先配置的频率资源进行感知。例如，终端设备可以基于来自基站的该资源分配模式的参数配置信息来获得预先配置的频率资源。
资源感知的目的在于获得发送终端设备可以使用的时频资源。可以通过任何方式进行资源感知。例如，发送终端设备可以接收直通链路控制信息(例如NR系统中的SCI(Sidelink Control Information))并对其解码。由此，发送终端设备可以排除在SCI中已明确分配了的时频资源。又例如，发送终端设备可以在资源窗内对预先配置的频率资源在频域进行测量(例如测量RSRP、RSRQ、SNR、SNIR等)。由此，发送终端设备可以排除测量值大于预先设定的阈值的频率资源。
基于404处的资源感知结果，发送终端设备可以获得可使用的时频资源集合。在406处，发送终端设备可以从该时频资源集合中筛选期望的时频资源。例如，该筛选可以是随机选择或者是基于频域测量值的选择。
在第二分配模式下，发送终端设备可以从预先配置的资源中选择时频资源，替代由其他设备专门调度资源。因此，发送终端设备可以快速地获得时频资源。在信道忙碌程度较低的情况，发送终端设备快速地获得时频资源的成功率会很高。在一定程度上，第二分配模式可以有利于减小直通链路通信的时延以及提高可靠性，对于例如高可靠和低延迟通信(Ultra-Reliable and Low Latency Communication,URLLC)业务是有利的。
第三分配模式可以包括由发送终端设备向资源调度设备请求时频资源以及由资源调度设备向发送终端设备分配时频资源。资源调度设备可以是基站之外的另一实体，其被配置为向集群中的终端设备分配用于直通链路通信的时频资源。基站可以预先分配资源池给资源调度设备，以便该资源调度设备进一步向终端设备分配。
图5示出了根据实施例的第三分配模式的示例操作。如图5所示，操作500包括在501处资源调度设备向基站110发送资源池调度请求消息，以请求基站110分配资源池供资源调度设备进一步分配给集群中的终端设备进行直通链路通信。在503处，基站基于资源请求向资源调度设备授权资源池，资源调度设备从基站110接收资源池授权消息。在505处，终端设备120-1可以作为集群的成员，向资源调度设备发送调度请求， 以请求进行直通链路通信的资源。在507处，响应于接收到来自终端设备120-1的资源调度请求消息，资源调度设备可以从资源池中选择时频资源以授权给终端设备120-1。在实施例中，调度请求可以包括基站预先配置给终端设备120-1的针对第三分配模式的参数配置信息，或者资源调度设备可以预先知晓该参数配置信息，使得资源调度设备可以基于该参数配置信息为终端设备120-1分配时频资源。在509处，所分配的时频资源可以由终端设备120-1用于与终端设备120-2的直通链路通信。
在实施例中，资源调度设备可以是基站之外的任何设备，例如可以是集群中的终端设备之一。相比与基站，资源调度设备可以更加靠近终端设备的集群，因此能够更好的感知局部区域的资源使用情况，有利于组播通信。例如，资源调度设备可以通过参照图4中描述的资源感知操作404感知集群中资源的使用情况，或者可以收集各终端设备的感知结果分析资源使用情况，从而能够以较低的时延分配适当的时频资源给终端设备。因此，相比于第一分配模式，第三分配模式可以更好地降低直通链路通信的时延并提高可靠性，满足例如URLLC业务的QoS需求。
时频资源选择
在本公开中，发送终端设备可以通过至少两种分配模式查找时频资源。所述至少两种分配模式可以包括第一分配模式、第二分配模式和/或其他可能的分配模式。对于第一分配模式，发送终端设备可以向基站发送资源调度请求消息，并从基站接收资源授权消息。对于第二分配模式，发送终端设备可以感知并查找时频资源。相应地，候选资源集合至少包括与第一和第二分配模式所对应的时频资源。
所述至少两种分配模式可以包括第一分配模式、第三分配模式和/或其他可能的分配模式。对于第一分配模式，发送终端设备可以向基站发送资源调度请求消息，并从基站接收资源授权消息。对于第三分配模式，发送终端设备可以向集群调度设备发送资源调度请求消息，并从集群调度设备接收资源授权消息。相应地，候选资源集合至少包括与第一和第三分配模式所对应的时频资源。
所述至少两种分配模式可以包括第二分配模式、第三分配模式和/或其他可能的分配模式。对于第二分配模式，发送终端设备可以感知并查找时频资源。对于第三分配模式，发送终端设备可以向集群调度设备发送资源调度请求消息，并从集群调度设备接收资源授权消息。相应地，候选资源集合至少包括与第二和第三分配模式所对应的时频资 源。
在获得候选资源集合后，发送终端设备可以基于直通链路通信的QoS需求和候选资源集合中的时频资源的属性来选择时频资源。在实施例中，可能有单个一种或多于一种分配模式所对应的时频资源被选择。
图6示出了根据实施例的选择时频资源的示意图。图6示出了包括两种分配模式(即模式1和模式2)所对应的时频资源的候选资源集合。可以类似地理解候选资源集合包括更多种分配模式所对应的时频资源的情况。
候选资源集合中不同分配模式所对应的时频资源可以具有不同的属性。如图6所示，模式1所对应的时频资源在时间上晚于模式2所对应的时频资源，例如晚2个OFDM符号。模式1所对应的时频资源(例如2个子载波宽度)在频域上多于模式2所对应的时频资源(例如1个子载波宽度)。模式1所对应的时频资源在时域是离散的，模式2所对应的时频资源在时域是连续的。模式1所对应的时频资源可能性能优于模式2所对应的时频资源，或者相反；或者模式1所对应的时频资源有一部分性能优于模式2所对应的时频资源。
直通链路通信可以具有不同的QoS需求，例如URLLC业务期望低时延和高可靠性，其他业务可能期望频域较宽的资源或时域连续的资源。相应地，发送终端设备可以为不同的业务选择匹配的时频资源。
例如，可以基于资源在时域的先后选择时频资源。由于模式2所对应的资源在时域上靠前，该资源可以被选择用于URLLC业务以减小等待时延。例如，可以基于资源性能选择时频资源。可以从模式1和模式2所对应的整体资源中选择性能较好的资源(例如干扰较小)，该资源可以被选择用于URLLC业务以提高可靠性。
可以理解，模式1或模式2可以对应于以上第一至第三分配模式中的任何一种。包括不同分配模式所对应的时频资源的候选资源集合为发送终端设备选择直通链路通信的资源提供了灵活性，发送终端设备更容易选择出与业务QoS需求匹配的时频资源。图6仅示出资源选择的一个示例。可以理解，不同模式所分配的资源的相对性能具有不确定性。然而，发送终端设备可以从候选资源集合中选择合适的资源(可以是通过一种或多种模式分配的)进行直通链路通信。
在根据本公开的资源分配和选择方案中，更容易实现直通链路通信的高可靠性和低延迟，对于URLLC业务是有利的。在例如信道状态忙碌或者存在较大信道干扰的情况下，相比于通过单个模式进行资源分配，根据本公开的技术方案优势更加明显，例如有利于在更广泛的场景下支持URLLC业务。
图7示出了根据实施例的用于通过两种分配模式选择时频资源的一个示例性信令流程。所选择的时频资源用于终端设备之间的直通链路通信。这两种分配模式分别对应于第一分配模式和第二分配模式。可以由基站110、终端设备120执行该信令流程。
如参照图3所描述的，在终端设备120与基站110建立连接后，基站110通过RRC信令向终端设备120发送不同资源分配模式的参数配置信息。基于这样的参数配置信息，终端设备120可以获得并选择用于直通链路通信的时频资源。如图7所示，基于到终端设备120-2的直通链路通信的需求，终端设备120-1一方面在702处向基站110发送资源调度请求消息，另一方面在704处进行资源感知。响应于接收到来自终端设备120-1的资源调度请求消息，在706处，基站110可以从资源池中选择时频资源以授权给终端设备120-1。在704处，资源感知可以包括终端设备120-1在资源窗中对预先配置的频率资源进行感知。通过资源感知，终端设备120-1可以排除在SCI中已明确分配了的时频资源，以及/或者排除测量值表明已被使用的频率资源。由于终端设备120-1可以还通过资源感知获得时频资源，因此可以以低于直通链路通信实际需求的方式向基站110发送资源调度请求消息。在一些实施例中，这种方式可能有利于基站110更快地或者以更高的成功率确定要授权给终端设备120-1的时频资源。
在708处，终端设备120-1获得候选资源集合，该候选资源集合包括通过第一和第二分配模式查找到的时频资源。终端设备120-1进一步从候选资源集合中选择时频资源，用于进行到接收终端设备120-2的直通链路通信。由于候选资源集合包括通过多种分配模式查找到的时频资源，终端设备120-1可以选择更好地满足直通链路的QoS需求的时频资源，如参照图6所描述的。
在710处，在选择了时频资源后，终端设备120-1向终端设备120-2通知所选择的时频资源，用于进行到终端设备120-2的直通链路通信。例如，可以通过直通链路控制信息传送具体时频资源信息或索引来向终端设备120-2通知所选择的时频资源。在712处，终端设备120-1还向基站110发送资源选择信息，该资源选择信息指示资源选 择情况，例如特定资源是否被选择。
在714处，终端设备120-1通过所选择的时频资源经由直通链路进行到终端设备120-2的通信。
图8示出了根据实施例的用于通过两种分配模式选择时频资源的另一个示例性信令流程。所选择的时频资源用于终端设备之间的直通链路通信。这两种分配模式分别对应于第一分配模式和第三分配模式。可以由基站110、终端设备120以及资源调度设备执行该信令流程。
如图8所示，基于到终端设备120-2的直通链路通信的需求，终端设备120-1一方面在802处向基站110发送资源调度请求消息，另一方面在804处向资源调度设备发送资源调度请求消息。响应于接收到来自终端设备120-1的资源调度请求消息，在806处，基站110可以从资源池中选择时频资源以授权给终端设备120-1。响应于接收到来自终端设备120-1的资源调度请求消息，在808处，资源调度设备可以从资源池中选择时频资源以授权给终端设备120-1。由于终端设备120-1可以从多个来源获得时频资源，因此可以以低于直通链路通信实际需求的方式向基站110或者资源调度设备发送资源调度请求消息。在一些实施例中，这种方式可能有利于基站110或者资源调度设备更快地或者以更高的成功率确定要授权给终端设备120-1的时频资源。
在810处，终端设备120-1获得候选资源集合，该候选资源集合包括通过第一和第三分配模式查找到的时频资源。终端设备120-1进一步从候选资源集合中选择时频资源，用于进行到接收终端设备120-2的直通链路通信。由于候选资源集合包括通过多种分配模式查找到的时频资源，终端设备120-1可以选择更好地满足直通链路的QoS需求的时频资源，如参照图6所描述的。
在812处，在选择了时频资源后，终端设备120-1向终端设备120-2通知所选择的时频资源，用于进行到终端设备120-2的直通链路通信。在814处，终端设备120-1还向基站110发送资源选择信息，该资源选择信息指示资源选择情况，例如特定资源是否被选择。
在816处，终端设备120-1通过所选择的时频资源经由直通链路进行到终端设备120-2的通信。
图9A和图9B示出了根据实施例的用于多种分配模式的资源池示意图。在图9A的示例中，不同的资源分配模式可以对应于不同的资源池。以两种分配模式为例，资源池A可以对应于第一分配模式，资源池B可以对应于第二或第三分配模式。类似地，可以为三种分配模式配置三个单独的资源池。可以为三种分配模式配置两个单独的资源池，例如第二和第三分配模式可以对应于单个资源池。在图9B的示例中，不同的资源分配模式可以对应于相同的资源池。例如，资源池C可以对应于第一至第三分配模式中的至少两种分配模式的组合。
应理解，资源池表示特定时频资源的集合，但并不在时域或频域对资源形成任何限定。相反，单个资源池中的资源在时域或频域可以是连续或者离散的。以NR系统为例，单个资源池中的资源可以对应单个或多个带宽部分(Bandwidth Part,BWP)，多个资源池中的资源可以对应相同或不同的BWP。发送和接收终端设备120可以向基站110报告设备能力来激活多个资源池或多个BWP中的资源。例如，如果一个或多个资源池在同一个BWP中，则激活该BWP和BWP中的一个或多个资源池；如果一个或多个资源池在多个BWP中，则激活这多个BWP和相应的资源池。
资源选择通知
在本公开中，在选择了用于直通链路通信的时频资源后，发送终端设备可以通过直通链路控制信息(例如NR系统中的SCI)传送具体时频资源信息或索引，来向接收终端设备通知所选择的时频资源。在NR系统中，可以通过物理直通控制信道(PysicalSidelinkControl Channel,PSCCH)来传输SCI。
在一个实施例中，可以通过SCI中的时频资源字段来直接指示资源位置。在另一个实施例中，可以在SCI中增加资源池索引字段，例如称为ResourceIndex(如表一所示)，用于指示特定资源池。可以通过SCI中的时频资源字段来指示时频资源在该特定资源池中的具体位置。通过资源池索引字段和时频资源字段也可以唯一地指示用于直通链路通信的时频资源。
在后一方式中，在特定资源池中指示时频资源所需要的比特数小于前一方式中在整体资源中指示时频资源所需要的比特数。即，通过使用索引值指示资源池可以减少用于通知资源选择的信令开销。相应地，基站110可以通过RRC信令为终端设备120预先配置多个资源池与索引值的对应关系。

资源选择报告
在本公开中，在选择了用于直通链路通信的时频资源后，发送终端设备可以通过物理上行链路控制信道(PysicalUplink Control Channel,PUCCH)传送资源选择信息，来向基站通知所选择的时频资源。在NR系统中，可以通过UCI(Uplink Control Information)来携带资源选择信息。资源选择信息可以向基站指示用于直通链路通信的资源选择情况。例如，资源选择信息可以指示第一分配模式所对应的(基站所分配的)时频资源是否被选择，或者还可以指示任何分配模式所对应的时频资源中被选择的具体时频资源。
在一个实施例中，可以通过PUCCH信道上的第一指示符来指示第一分配模式所对应的时频资源是否被选择。第一指示符可以仅具有1个比特。具体地，该指示符取值为0可以指示时频资源未被选择，该指示符取值为1可以指示时频资源被选择。在一个实施例中，为了减少UCI开销，可以使用现有UCI字段来携带该1比特指示符。现有UCI字段包括例如用于HARQ反馈的ACK/NACK字段。
在一个实施例中，终端设备可能更容易选择第一分配模式对应的时频资源，例如由于第一分配模式所对应的时频资源具有较高的优先级。相应地，可以仅发送取值为0的第一指示符；在第一分配模式所对应的时频资源被选择的情况下，不发送第一指示符。在另一个实施例中，终端设备可能更容易选择其他分配模式对应的时频资源，例如由于第一分配模式所对应的时频资源具有较低的优先级。相应地，可以仅发送取值为1的第一指示符；在第一分配模式所对应的时频资源未被选择的情况下，不发送第一指示符。
一经获知基站所分配的资源是否被发送终端设备选择，基站可以基于资源选择信息来进行进一步的资源调度。例如，基站可以释放已分配给发送终端设备但未被选择的时频资源，以便在进一步的资源调度中避免资源冲突。
在一个实施例中，可以通过PUCCH信道上的第二指示符来指示任何分配模式所对 应的时频资源中被选择的具体时频资源。第二指示符可以对应多个比特。可以使用相应数量的比特分别从频域和时域对具体时频资源进行描述，比特的相应数量可以与以下因素有关，即直通链路子信道数量和可为直通链路预留资源的最大数量。当然，可以预先为具体时频资源配置相应的索引值，例如通过RRC信令。另选地，可以使用索引值对具体时频资源进行描述。图10示出了根据实施例的用于指示时频资源的第二指示符的示例格式。在图10中，参数
Figure PCTCN2021109664-appb-000002
表示直通链路子信道数量，参数sl-MaxNumPerReserve表示可为直通链路预留资源的最大数量。可以通过高层信令(例如RRC信令)配置上述参数。
第二指示符可以有利于基站获知资源选择的详细信息，以便释放未被选择的时频资源以及在进一步的资源调度中避免资源冲突。
图11示出了根据实施例的用于无线通信的示例方法。方法1100可以由发送终端设备120-1执行，以便进行到接收终端设备120-2的直通链路通信。如图11所示，该方法1000可以包括通过至少两种分配模式查找时频资源以获得候选资源集合(框1105)，从候选资源集合中选择时频资源(框1110)。该方法还可以包括向接收终端设备120-2通知所选择的时频资源，用于进行到接收终端设备120-2的直通链路通信(框1115)。该方法还可以包括向基站110发送资源选择信息，该资源选择信息可以指示资源选择情况，例如特定资源是否被选择(框1120)。
在一个实施例中，通过至少两种分配模式查找时频资源包括：对于第一分配模式，向基站110发送资源调度请求消息，并从基站110接收资源授权消息；对于第二分配模式，感知并查找时频资源。候选资源集合可以包括与第一和第二分配模式所对应的时频资源。
在一个实施例中，对于第二分配模式，感知并查找时频资源包括在资源窗中感知资源，以及基于感知结果筛选期望的资源。
在一个实施例中，通过至少两种分配模式查找时频资源包括：对于第一分配模式，向基站110发送资源调度请求消息，并从基站110接收资源授权消息；对于第三分配模式，向集群调度设备发送资源调度请求消息，并从集群调度设备接收资源授权消息。候选资源集合可以包括与第一和第三分配模式所对应的时频资源。
在一个实施例中，发送终端设备120-1用作资源调度设备，并且方法1100还包括向基站110发送资源池调度请求消息，并从基站110接收资源池授权消息；响应于接收到来自特定终端设备的资源调度请求消息，从资源池中选择时频资源以授权给特定终端设备。
在一个实施例中，选择时频资源包括基于直通链路通信的QoS需求和候选资源集合中的时频资源的属性来选择时频资源，其中单个一种或多于一种分配模式所对应的时频资源被选择。
在一个实施例中，资源选择信息向基站110指示第一分配模式所对应的时频资源是否被选择。
在一个实施例中，资源选择信息还向基站110指示第二或第三分配模式所对应的时频资源中被选择的时频资源。
在一个实施例中，方法1100还包括通过RRC信令从基站接收至少两种分配模式的参数配置。
在一个实施例中，方法1100还包括从另一终端设备接收该另一终端设备所选择的时频资源信息，用于接收来自该另一终端设备的直通链路通信。
在一个实施例中，方法1100还包括通过直通链路控制信息传送具体时频资源信息或索引来向终端设备120-2通知所选择的时频资源。
图12示出了根据实施例的用于无线通信的另一示例方法。方法1200可以由基站110执行，以为进行直通链路通信的终端设备120分配时频资源。如图12所示，该方法1200可以包括接收来自发送终端设备120-1的资源调度请求消息，该资源调度请求消息请求时频资源以用于由发送终端设备120-1进行到接收终端设备120-2的直通链路通信。该方法1200还可以包括通过第一分配模式向发送终端设备120-1分配时频资源，向发送终端设备120-1发送资源授权消息。该方法1200还可以包括接收来自发送终端设备120-1的资源选择信息，该资源选择信息指示第一分配模式所对应的时频资源是否被发送终端设备120-1选择。
在一个实施例中，资源选择信息还指示终端设备120-1从至少另一分配模式所对应的时频资源中选择的时频资源。
在一个实施例中，方法1200还包括通过RRC信令向终端设备120-1发送第一分配模式和至少另一分配模式的参数配置。
在一个实施例中，方法1200还包括基于资源选择信息进行进一步的资源分配，例如释放已授权但未被选择的时频资源。

以下将参照图14至图17描述根据本公开的应用示例。
[关于基站的应用示例]
以下参照图14和图15描述了gNB的示意性配置。
第一应用示例
图14是示出可以应用本公开内容的技术的gNB的示意性配置的第一示例的框图。gNB 1400包括多个天线1410以及基站设备1420。基站设备1420和每个天线1410可以经由RF线缆彼此连接。在一种实现方式中，此处的gNB 1400(或基站设备1420)可以对应于上述电子设备300A、1300A和/或1500B。
