Description

一种直连通信方法和装置 技术领域
本公开涉及通信技术领域，具体而言，涉及一种直连通信方法和装置，通信装置和计算机可读存储介质。
背景技术
Slidelink直连链路是一种端到端D2D通信技术，也即终端与终端之间直连通信。该技术主要包含两个功能：一个是D2D发现功能，它能够使得用户设备之间通过射频空口在近场相互发现；另一个是D2D通信功能，它能够使得用户设备之间通过射频空口直接进行数据传输而避免通过网络进行路由，而网络仅只负责一些资源协调和安全管控。
基于Slidelink的直连通信支持三种传输方式，分别为单播，多播和广播。
为了节省终端在进行直连通信时的设备功耗，引入了Sidelink DRX(非连续接收，Discontinuous Reception)。对于广播和组播，接收终端的Sidelink DRX配置根据业务类型决定；对于单播，接收终端的Sidelink DRX配置由发送终端或者发送终端的基站来配置。
然而，不同的终端对Sidelink DRX的使用情况不同，终端之间在基于Sidelink DRX进行直连通信时，存在一些问题。
发明内容
有鉴于此，本公开的实施例提出了一种直连通信方法和装置，以解决相关技术中的技术问题。
根据本公开实施例的第一方面，提出一种直连通信方法，由第一终端执行，所述方法包括：在所述第一终端基于直连链路Sidelink与目的地址进行直连通信时，确定是否忽略Sidelink非连续接收DRX的限制。
根据本公开实施例的第二方面，提出一种直连通信装置，应用于第一终端，所述装置包括：通信模块，被配置为在所述第一终端基于直连链路Sidelink与目的地址进行直连通信时，确定是否忽略Sidelink非连续接收DRX的限制。
根据本公开实施例的第三方面，提出一种通信装置，包括：
处理器；
用于存储处理器可执行指令的存储器；
其中，所述处理器被配置为执行上述第一方面所述的直连通信方法。
根据本公开实施例的第六方面，提出一种计算机可读存储介质，用于存储计算机程序，所述程序被处理器执行时实现上述第一方面所述的直连通信方法中的步骤。
根据本公开的实施例，终端不是在任何情况下都采用Sidelink DRX的方式进行直连通信，而是根据实际情况确定是否忽略Sidelink DRX的限制。一方面，可以避免Sidelink DRX导致的不必要的数据延迟；另一方面，也可以避免发送端与接收端对Sidelink DRX的使用不匹配而导致的数据丢失。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。

应当理解，尽管在本公开实施例可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本公开实施例范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。

图1是根据本公开的实施例示出的一种直连通信方法的示意流程图。本实施例所示的直连通信方法可以适用于第一终端，所述第一终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。所述第一终端可以作为用户设备与基站通信，所述基站包括但不限于4G基站、5G基站、6G基站等通信系统中的基站。如图1所示，所述直连通信方法可以包括以下步骤：
在步骤S101中，在所述第一终端基于直连链路Sidelink与目的地址进行直连通信时，确定是否忽略Sidelink非连续接收DRX的限制。
在一个实施例中，第一终端可以基于Sidelink与目的地址进行直连通信。例如，在进行单播通信时，该目的地址为对端设备的地址；在进行组播通信时，该目的地址为组播组的地址；在进行广播通信时，该目的地址为广播地址。
在一个实施例中，第一终端可以是数据发送端，则第一终端可以将数据发送给 目的地址。数据接收端可以称为第二终端，第二终端可以接收发送给该目的地址的数据。以组播通信为例，第一终端可以将数据发送给组播组地址，第二终端可以接收发送给该组播组地址的数据。
在一个实施例中，第一终端可以是数据接收端，则第一终端可以接收发送给目的地址的数据。数据发送端、以及其他数据接收端，可以称为第二终端。作为数据发送端的第二终端，可以将数据发送给目的地址；作为数据接收端的第二终端，与第一终端类似，可以接收发送给目的地址的数据。需要说明的是，若与目的地址的通信为单播通信，则第二终端仅包括数据发送端；若与目的地址的通信为组播或广播通信，则第二终端包括数据发送端、以及还可以包括若干个其他数据接收端。
在一个实施例中，若第一终端为支持Sidelink DRX功能的终端，则终端在确定需要与目的地址进行基于sidelink的通信后，在执行通信之前，例如在发送数据或接收数据之前，先确定是否忽略Sidelink DRX的限制。
需要说明的是，基于Sidelink DRX功能，终端可以切换为睡眠状态或唤醒状态。对于接收端，在处于唤醒状态时(或称为激活时间内)，监听sidelink信道以接收数据，而在睡眠状态时不监听sidelink信道，从而起到节能的作用；对于发送端，可以根据接收端的DRX状态来确定是否发送数据，在接收端处于唤醒状态时，发送端发送数据，而在接收端处于睡眠状态时，发送端不发送数据。
在一个实施例中，第一终端忽略Sidelink DRX的限制，可以是不考虑是否处于唤醒状态就执行对应的操作。例如第一终端作为数据接收端，忽略Sidelink DRX限制，可以为在所有sidelink接收资源位置上监听向所述目的地址发送的通信；或者，第一终端作为数据发送端，忽略Sidelink DRX限制，可以为确定所有sidelink发送资源均可以用于向所述目的地址发送数据。
在一个实施例中，若第一终端确定不忽略Sidelink DRX的限制，则仍基于Sidelink DRX进行调度，即只在接收端的激活时间内进行数据接收和发送，从而可以节约终端功耗。
根据图1所示的实施例，终端不是在任何情况下都采用Sidelink DRX的方式进行直连通信，而是根据实际情况确定是否忽略Sidelink DRX的限制。一方面，可以避免Sidelink DRX导致的不必要的数据延迟；另一方面，也可以避免发送端与接收端对Sidelink DRX的使用不匹配而导致的数据丢失。
终端确定是否忽略Sidelink DRX的方法可以有多种，下面结合具体的实施例进行介绍。
图2是根据本公开的实施例示出的另一种直连通信方法的示意流程图。如图2所示，所述确定是否忽略Sidelink DRX的限制，包括：
在步骤S201中，确定是否存在不能使用Sidelink DRX的第二终端与所述目的地址进行直连通信。
在一个实施例中，根据通信的不同类型，与目的地址进行直连通信的第二终端也不同。例如对于单播通信，第二终端为第一终端的对端设备；对于组播通信，第二终端为组播组中除第一终端以外的其他终端；对于广播通信，第二终端为广播域中除第一终端以外的其他终端。
下面对第一终端是数据发送端和数据接收端，分别进行说明。
在一个实施例中，第一终端可以是数据发送端，第一终端与目的地址进行通信包括：第一终端向目的地址发送数据。与目的地址进行直连通信的第二终端为数据接收端，即接收发送到目的地址的数据。
对于单播通信，与目的地址进行直连通信的第二终端为目的地址所指示的终端。基于此，第一终端可以确定目的地址所指示的终端是否能使用Sidelink DRX，若能，则确定不存在不能使用Sidelink DRX的第二终端与所述目的地址进行直连通信；若不能，则确定存在不能使用Sidelink DRX的第二终端与所述目的地址进行直连通信。
对于组播和广播通信，与目的地址进行直连通信的第二终端为从目的地址接收数据的终端，例如为组播组中的其他终端、或者为广播域中的其他终端。基于此，第一终端可以确定组播组或广播域中是否有至少一个不能使用Sidelink DRX的第二终端。若组播组或广播域中所有终端均能使用Sidelink DRX，则确定不存在不能使用Sidelink DRX的第二终端与所述目的地址进行直连通信；若组播组或广播域中存在至少一个不能使用Sidelink DRX的第二终端，则确定存在不能使用Sidelink DRX的第二终端与所述目的地址进行直连通信。
在一个实施例中，第一终端可以是数据接收端，第一终端与目的地址进行通信包括：第一终端接收发送到目的地址的数据。与目的地址进行直连通信的第二终端包括数据发送端、或者还可以包括其他数据接收端(即除第一终端以外、其他从目的地址接收数据的终端)。
对于单播通信，与目的地址进行直连通信的第二终端为数据发送端(即向目的地址发送数据的终端)。基于此，第一终端可以确定单播通信的数据发送端是否能使用Sidelink DRX，若能，则确定不存在不能使用Sidelink DRX的第二终端与所述目的地址进行直连通信；若不能，则确定存在不能使用Sidelink DRX的第二终端与所述目的地址进行直连通信。
对于组播和广播通信，与目的地址进行直连通信的第二终端包括：数据发送端(即向目的地址发送数据的终端)、以及至少一个其他数据接收端(即除第一终端以外、从目的地址接收数据的其他终端)，也就是组播组中的其他终端、或者广播域中的其他终端。基于此，第一终端可以确定组播组或广播域中是否有至少一个不能使用Sidelink DRX的第二终端。若组播组或广播域中所有终端均能使用Sidelink DRX，则确定不存在不能使用Sidelink DRX的第二终端与所述目的地址进行直连通信；若组播组或广播域中存在至少一个不能使用Sidelink DRX的第二终端，则确定存在不能使用Sidelink DRX的第二终端与所述目的地址进行直连通信。
在一个实施例中，第一终端可以确定与目的地址进行直连通信的至少一个第二终端中，是否存在不能使用Sidelink DRX的第二终端。
需要说明的是，终端是否能使用Sidelink DRX，至少包括以下2种情况，一种为终端所支持的通信标准的版本不支持Sidelink DRX功能；第二种为终端根据基站指示、或者根据业务类型确定，在进行本次直连通信时不启用Sidelink DRX功能。
在步骤S202中，若存在，则确定忽略Sidelink DRX的限制。
在一个实施例中，若第一终端确定存在不能使用Sidelink DRX的第二终端与目的地址进行直连通信，则确定忽略Sidelink DRX的限制。
若第一终端进行单播通信，目的地址为对端设备(即第二终端)的地址，第一终端若确定第二终端不能使用Sidelink DRX，则忽略Sidelink DRX的限制。
若第一终端进行组播通信，目的地址为组播组地址，第一终端若确定组播组中存在不能使用Sidelink DRX的第二终端，则忽略Sidelink DRX的限制。
若第一终端进行广播通信，目的地址为广播地址，第一终端若确定广播域中存在不能使用Sidelink DRX的第二终端，则忽略Sidelink DRX的限制。
需要说明的是，若第一终端为发送端，在接收端中存在不能使用Sidelink DRX的第二终端的情况下，第一终端为了提高发送数据的及时性，避免不必要的延时，可 以忽略Sidelink DRX的限制，例如可以确定所有sidelink发送资源均可以用于发送数据。
若第一终端为接收端，在其他接收端中存在不能使用Sidelink DRX的第二终端的情况下，发送端在发送数据时忽略Sidelink DRX的限制，即不限制在激活时间内发送数据，基于此，若第一终端仅在激活时间内接收数据，则会导致数据丢失。因此，为了保证接收数据的可靠性，第一终端可以忽略Sidelink DRX的限制，例如可以在所有sidelink接收资源位置上监听向所述目的地址发送的通信。
在一个实施例中，若确定不存在不能使用Sidelink DRX的第二终端与所述目的地址进行直连通信，则不忽略Sidelink DRX的限制，仍基于Sidelink DRX进行直连通信。
图3是根据本公开的实施例示出的另一种直连通信方法的示意流程图。如图3所示，所述确定是否存在不能使用Sidelink DRX的第二终端与所述目的地址进行直连通信，包括：
在步骤S301中，确定所述第二终端支持的通信标准；
在步骤S302中，若至少一个所述第二终端不支持指定版本的通信协议，则确定存在不能使用Sidelink DRX的第二终端与所述目的地址进行直连通信；其中，所述指定版本为能使用Sidelink DRX的版本。
在一个实施例中，第一终端可以对第二终端所支持的通信标准进行检测，若检测到至少一个第二终端不支持指定版本的通信协议，则确定存在不能使用Sidelink DRX的第二终端与所述目的地址进行直连通信。
举例来说，指定版本可以是5G通信标准中R17(Release17)版本、以及R17以后的版本。例如，若第一终端检测到至少一个第二终端所支持的通信标准版本为R16，则确定该第二终端不支持指定版本的通信协议，从而确定存在不能使用Sidelink DRX的第二终端与所述目的地址进行直连通信。
在一个实施例中，若检测到所有第二终端均支持指定版本的通信协议，则确定不存在不能使用Sidelink DRX的第二终端与所述目的地址进行直连通信，从而在进行直连通信时，基于Sidelink DRX进行调度，即只在接收端的激活时间内进行数据接收和发送。
图4是根据本公开的实施例示出的另一种直连通信方法的示意流程图。如图4 所示，所述确定是否存在不能使用Sidelink DRX的第二终端与所述目的地址进行直连通信，包括：
在步骤S401中，接收指定小区广播的系统信息；
在步骤S402中，若所述系统信息未携带用于配置Sidelink DRX的参数，则确定存在不能使用Sidelink DRX的第二终端与所述目的地址进行直连通信。
在一个实施例中，指定小区可以为与所述直连通信的通信频率相匹配的小区。
需要说明的是：在进行直连通信时，第一终端和目的地址进行直连通信、第二终端和目的地址进行直连通信时，都是基于直连通信的通信频率，该通信频率、与第一终端与其服务小区的通信频率、以及与第二终端与其服务小区的通信频率可以是相同，也可以是不同的。而由于第一终端和第二终端在直连通信的通信频率上工作，因此，位于该通信频率上的基站可以与该第一终端和第二终端进行交互，例如可以向第一终端和第二终端发送系统消息。举例来说，若第一终端和第二终端支持Sidelink DRX，则与直连通信的通信频率相匹配的小区可以对第一终端和第二终端进行Sidelink DRX配置，即通过广播系统消息向其下发用于配置Sidelink DRX的参数。
基于此，在一个实施例中，终端可以接收指定小区的系统消息，若至少一个指定小区的系统消息中未用于配置Sidelink DRX的参数，且第一终端可以确定自身能使用Sidelink DRX，因而第一终端可以确定至少存在一个不能使用Sidelink DRX的第二终端。
在一个实施例中，指定小区可以为所述第一终端的服务小区和邻小区中的至少一个。
需要说明的是：基于sidelink的直连通信，通常为近距离的终端与终端之间进行直连通信。因此，第一终端可以认为，与目的地址进行直连通信的若干个第二终端，处于第一终端的服务小区或邻小区。与前述实施例类似地，若第一终端和第二终端支持Sidelink DRX，服务小区或邻小区可以对第一终端和第二终端进行Sidelink DRX配置，即通过广播系统消息向其下发用于配置Sidelink DRX的参数。
基于此，在一个实施例中，第一终端可以接收服务小区和/或邻小区广播的系统消息，也可以说，第一终端接收第二终端可以所属的所有小区广播的系统消息。若至少一个指定小区的系统消息中未配置用于Sidelink DRX的参数，且第一终端可以确定自身能使用Sidelink DRX，因而第一终端可以确定至少存在一个不能使用Sidelink  DRX的第二终端。
根据图4所示实施例，第一终端可以通过接收指定小区的系统消息，根据系统消息是否配置预测Sidelink DRX的参数，来预测是否存在不能使用Sidelink DRX的第二终端与所述目的地址进行直连通信，方法简便高效，从而可以有效地确定在进行直连通信时是否忽略Sidelink DRX的限制。
图5是根据本公开的实施例示出的另一种直连通信方法的示意流程图。如图5所示，所述确定是否存在不能使用Sidelink DRX的第二终端与所述目的地址进行直连通信，包括：
在步骤S501中，接收指定小区广播的系统信息。
在步骤S502中，若所述系统信息指示所述指定小区不能使用Sidelink DRX，则确定存在不能使用Sidelink DRX的第二终端。
在一个实施例中，指定小区可以为与所述直连通信的通信频率相匹配的小区。
需要说明的是：由于第一终端和第二终端在直连通信的通信频率上工作，因此，位于该通信频率上的基站可以对该第一终端和第二终端进行指示，例如，若小区通过系统消息只是指示不能使用Sidelink DRX，则第一终端和第二终端不能使用Sidelink DRX。
基于此，在一个实施例中，终端可以接收指定小区的系统消息，若至少一个指定小区的系统消息中指示该小区不能使用Sidelink DRX，则确定存在不能使用Sidelink DRX的第二终端。
在一个实施例中，指定小区可以为第一终端的服务小区和邻小区中的至少一个。
需要说明的是：由于直连通信通常用于近距离的终端与终端之间，因此第一终端可以认为，与目的地址进行直连通信的若干个第二终端，处于第一终端的服务小区或邻小区。也就是说，第二终端的服务小区，为第一终端的服务小区和/或邻小区。例如，若小区通过系统消息只是指示不能使用Sidelink DRX，则该小区中的终端不能使用Sidelink DRX。
基于此，在一个实施例中，第一终端可以接收服务小区和/或邻小区广播的系统消息，也可以说，第一终端接收第二终端可以所属的所有小区广播的系统消息。若 该至少一个指定小区的系统消息中指示不能使用Sidelink DRX，且第一终端可以认为至少存在一个不能使用Sidelink DRX的第二终端。
根据图5所示实施例，第一终端可以通过接收指定小区的系统消息，根据系统消息是否指示不能使用Sidelink DRX，来预测是否存在不能使用Sidelink DRX的第二终端与所述目的地址进行直连通信，方法简便高效，从而可以有效地确定在进行直连通信时是否忽略Sidelink DRX的限制。
图6是根据本公开的实施例示出的另一种直连通信方法的示意流程图。如图6所示，所述确定是否存在不能使用Sidelink DRX的第二终端与所述目的地址进行直连通信，包括：
在步骤S601中，获取Sidelink DRX配置。
在步骤S602中，向所述与目的地址进行直连通信的第二终端发送Sidelink DRX配置。
在一个实施例中，第一终端可以获取Sidelink DRX配置，例如，终端可以从自身保存的配置中获取，或者也可以向基站请求配置。
在一个实施例中，第一终端可以向各个第二终端发送Sidelink DRX配置。例如，若直连通信为组播通信，则可以向组播组中的其他终端发送Sidelink DRX配置；若直连通信为广播通信，则可以向广播域中的其他终端发送Sidelink DRX配置。在一个实施例中，第一终端可以通过单播的方式向各个第二终端发送Sidelink DRX配置。
在步骤S603中，若至少一个第二终端拒绝所述Sidelink DRX配置，则确定存在不能使用Sidelink DRX的第二终端与所述目的地址进行直连通信。
在一个实施例中，第二终端在接收到Sidelink DRX配置后，若接受该配置，则可以向第一终端返回配置成功的指示信息；若拒绝该配置，则可以向终端返回拒绝配置的指示信息。
基于此，在一个实施例中，第一终端可以根据第二终端是否返回拒绝配置的指示信息，来确定该第二终端能否使用Sidelink DRX。若第二终端拒绝所述Sidelink DRX配置，则确定该第二终端不能使用Sidelink DRX。
在一个实施例中，若至少一个第二终端拒绝所述Sidelink DRX配置，则确定存在不能使用Sidelink DRX的第二终端与所述目的地址进行直连通信。
根据图6所示实施例，第一终端可以通过发送Sidelink DRX配置的方法，根据第二终端是否拒绝该配置来确定第二终端能否使用Sidelink DRX。根据本实施例方法，第一终端可以高效地确定在进行直连通信时是否忽略Sidelink DRX的限制。
图7是根据本公开的实施例示出的另一种直连通信方法的示意流程图。如图7所示，所述确定是否忽略Sidelink DRX的限制，包括：
在步骤S701中，获取所述直连通信的业务特性。
在步骤S702中，若所述业务特性指示所述业务为不支持Sidelink DRX，则确定忽略Sidelink DRX的限制。
在一个实施例中，第一终端可以确定根据直连通信所承载的业务来确定是否支持Sidelink DRX。
举例来说，第一终端中可以预先配置若干种业务类型、与该业务类型是否支持Sidelink DRX的指示信息。可选的，该配置可以是基站下发给第一终端的。基于该配置，第一终端可以根据确定直连通信所承载的业务所属的业务类型，若该类型为不支持Sidelink DRX，则该业务的业务特性指示所述业务为不支持Sidelink DRX，从而可以确定忽略Sidelink DRX的限制。
或者，也可以不对业务进行分类，而是根据业务的属性进行确定。例如，第一终端中也可以预先配置多个属性、以及每个属性是否支持Sidelink DRX。若直连通信所承载的业务的属性中，包含不支持Sidelink DRX的属性，则该业务的业务特性指示所述业务为不支持Sidelink DRX，从而可以确定忽略Sidelink DRX的限制。
根据图7所示实施例，第一终端可以基于直连通信所承载的业务进行判断，若该业务的业务特性指示不支持Sidelink DRX，则第一终端不需要对于目的地址进行通信的第二终端进行检测，即可以直接确定忽略Sidelink DRX的限制，提高了处理效率，既可以避免Sidelink DRX导致的不必要的数据延迟，也可以避免发送端与接收端对Sidelink DRX的使用不匹配而导致的数据丢失。
如前述实施例所述，第一终端可以为数据发送端，也可以为数据接收端，下面分别进行介绍。
在一个实施例中，所述第一终端为数据发送端，则第一终端若确定忽略Sidelink DRX的限制，还可以向基站发送指示信息，所述指示信息用于指示所述基站针对所述目的地址的数据发送忽略Sidelink DRX限制。
在一个例子中，若第一终端处于RRC连接态，则第一终端的直连通信受服务小区控制。第一终端在确定忽略Sidelink DRX的限制后，可以向基站进行上报，其中可以包括目的地址、以及针对所述目的地址的数据发送忽略Sidelink DRX限制的指示信息。
基于此，基站在向第一终端调度用于直连通信的资源时，不考虑Sidelink DRX限制，即sidelink发送资源不需要局限在Sidelink DRX激活时间内。由此，终端在基于基站调度的sidelink发送资源进行直连通信时，也相应的实现了忽略Sidelink DRX的限制。
可选的，第一终端可以在同一指示信息中向基站上报多个目的地址的发送情况，即向基站指示针对多个目的地址的数据发送是否忽略Sidelink DRX限制。若该多个目的地址的发送情况相同，例如均忽略Sidelink DRX限制、或者均不忽略Sidelink DRX限制，则第一终端可以仅向基站发送一个指示信息；若该多个目的地址的发送情况不同，例如部分忽略Sidelink DRX限制、部分不忽略Sidelink DRX限制，则第一终端向基站分别发送每个目的地址的指示信息。
在一个实施例中，所述第一终端为数据发送端，则第一终端确定忽略Sidelink DRX的限制，可以包括在选择用于向所述目的地址发送数据的sidelink资源时，忽略Sidelink DRX限制。
在一个例子中，若第一终端处于RRC非连接态，例如RRC空闲态或RRC非激活态，则第一终端的直连通信不受服务小区的控制。由此，第一终端可以自行选择用于直连通信的sidelink资源，且在选择资源时所有sidelink发送资源均可以用于向所述目的地址发送数据，而不收到Sidelink DRX的限制。
在一个实施例中，第一终端为数据接收端，则，则第一终端确定忽略Sidelink DRX的限制，包括：在忽略Sidelink DRX的限制的情况下，接收向所述目的地址发送的数据。
具体来说，第一终端不需要考虑是否处于DRX激活状态，而是在所有sidelink接收资源位置上持续监听向所述目的地址发送的数据。由此，第一终端可以接收到发送到该目的地址的数据。
与前述的直连通信方法的实施例相对应，本公开还提供了直连通信装置的实施例。

在一个实施例中，所述通信模块801，具体被配置为：接收指定小区广播的系统信息；若所述系统信息未携带用于配置Sidelink DRX的参数，则确定存在不能使用Sidelink DRX的第二终端与所述目的地址进行直连通信。

在一个实施例中，所述目的地址为Sidelink广播或组播的目的地址。

下面结合特定的技术细节，概括地示例性说明根据本公开的直连通信方法的机制。
在相关技术中，发送UE无法确定某个组播或广播的sidelink通信是否适用sidelink DRX，从而无法确定对应的sidelink通信的发送是否需要考虑sidelink DRX激活时间限制。或者，发送给UE的基站无法确定某个组播或广播的sidelink通信是否使用sidelink DRX，对应的sidelink资源调度是否需要考虑sidelink DRX激活时间限制，如果按照sidelink DRX激活时间调度发送资源，可能导致数据延迟。如果不考虑sidelink DRX激活时间调度发送资源，可能导致数据丢失。
为了解决上述技术问题，本公开可以采用如下直连通信方法：
在一个实施例中，UE确定某个目的地址的sidelink通信是否适用Sidelink DRX。
在一个实施例中，确定的方法包括以下任意一种或多种：
方式1，目的地址的sidelink通信是否有R16sidelink UE接收。如果有，则对应目的地址的sidelink通信不适用sidelink DRX。
方式2，小区系统广播中是否携带sidelink DRX参数，所述小区可以是服务小区也可以是邻小区。如果不携带，则广播和组播的sidelink通信不适用sidelink DRX。
作为一个实施例，所述小区为处于sidelink发送频率上的任一小区。
作为一个实施例，所述小区可以是服务小区也可以是邻小区。
方式3，小区系统广播中携带指示支持sidelink DRX功能，如果小区不支持sidelink DRX，则广播和组播的sidelink通信不适用sidelink DRX。
作为一个实施例，所述小区为处于sidelink发送频率上的任一小区。
作为一个实施例，所述小区可以是服务小区也可以是邻小区。
方式4，对端UE收到UE发送的DRX配置之后，回复拒绝Sidelink DRX指示，则对端UE的目的地址不适用sidelink DRX。
在一个实施例中，UE将目的地址是否适用sidelink DRX的信息上报给基站。
可选的，若当全部组播或广播地址都不适用sidelink DRX时，可以只上报一个指示。
在一个实施例中，UE在向不适用sidelink DRX的目的地址发送sidelink通信时，在所有发送资源上都可以发送。
在一个实施例中，基站收到某个目的地址不适用sidelink DRX之后，在调度对 应的sidelink发送资源时，不考虑sidelink DRX限制，即sidelink发送资源不需要局限在sidelink DRX激活时间内。
在一个实施例中，UE在接收不适用sidelink DRX的目的地址的sidelink通信时，不使用sidelink DRX。
