Description

通信方法、电子设备及存储介质 技术领域
本公开实施例涉及移动通信技术领域，具体而言，本公开实施例涉及一种通信方法、电子设备及存储介质。
背景技术
在目前所研究的无线保真(Wireless-Fidelity，Wi-Fi)技术中，为支持大规模物联网(Internet of Things，IoT)设备下的节能工作，提出了目标唤醒时间(Target Wake Time，TWT)机制；同时，为了保障时延敏感业务(Latency Sensitive Traffic)的传输，提出了限制目标唤醒时间(Restricted-TWT，R-TWT)机制。为了进一步降低Wi-Fi网络功耗，需要完善R-TWT机制。
发明内容
本公开实施例提供了一种通信方法、电子设备及存储介质，以进一步完善R-TWT机制，以进一步降低Wi-Fi网络功耗。
一方面，本公开实施例提供了一种通信方法，应用于站点设备，所述方法包括：
确定第一无线帧；其中，所述第一无线帧包括限制目标唤醒时间R-TWT调整信息，所述R-TWT调整信息指示所述站点设备对所述R-TWT的服务周期SP的调整操作，所述调整操作包括延长R-TWT SP或缩短R-TWT SP；
发送所述第一无线帧。
另一方面，本公开实施例还提供了一种通信方法，应用于接入点设备，所述方法包括：
接收第一无线帧；其中，所述第一无线帧包括限制目标唤醒时间R-TWT调整信息，所述R-TWT调整信息指示站点设备对所述R-TWT的服务周期SP的调整操作，所述调整操作包括延长R-TWT SP或缩短R-TWT SP。
另一方面，本公开实施例还提供了一种电子设备，所述电子设备为站点设备，所述电子设备包括：
确定模块，用于确定第一无线帧；其中，所述第一无线帧包括限制目标唤醒时间R-TWT调整信息，所述R-TWT调整信息指示所述站点设备对所述R-TWT的服务周期SP的调整操作，所述调整操作包括延长R-TWT SP或缩短R-TWT SP；
发送模块，用于发送所述第一无线帧。
另一方面，本公开实施例还提供了一种电子设备，所述电子设备为接入点设备，所述电子设备包括：
接收模块，用于接收第一无线帧；其中，所述第一无线帧包括限制目标唤醒时间R-TWT调整信息，所述R-TWT调整信息指示站点设备对所述R-TWT的服务周期SP的调整操作，所述调整操作包括延长R-TWT SP或缩短R-TWT SP。
本公开实施例还提供了一种电子设备，包括存储器、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，处理器执行程序时实现如本公开实施例中一个或多个所述的方法。
本公开实施例还提供了一种计算机可读存储介质，该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如本公开实施例中一个或多个所述的方法。
本公开实施例中，站点设备发送第一无线帧，在第一无线帧中携带R-TWT调整信息，指示站点设备对R-TWT SP的调整操作；所述调整操作包括延长R-TWT SP或缩短R-TWT SP；一方面，在初始R-TWT SP结束后，传输低时延业务的站点设备不能再向其关联的AP发送任何无线帧， 若初始R-TWT SP较短，将会导致站点设备和AP间所传输的低时延业务中断，影响通信质量；另一方面，在初始R-TWT SP内，其他非低时延业务不进行通信；若初始R-TWT SP过长，将会导致通信资源的浪费。因此，站点设备通过延长R-TWT SP或缩短R-TWT SP，提升低时延业务的传输质量以及避免通信资源的浪费。
本公开实施例附加的方面和优点将在下面的描述中部分给出，这些将从下面的描述中变得明显，或通过本公开的实践了解到。

其中，方法和装置是基于同一申请构思的，由于方法和装置解决问题的原理相似，因此装置和方法的实施可以相互参见，重复之处不再赘述。
如图1以及图2中所示，本公开实施例提供了一种通信方法，可选地，所述方法可应用于站点设备(Station，STA)；可选地，本公开实施例中，接入点(Access Point，AP)设备例如具有无线至有线桥接(Bridging)功能的设备，AP负责将有线网络所提供的服务延伸至无线网络；STA例如具有无线网络接入功能的电子设备，提供帧传递(Frame Delivery)服务让信息得以传递。
参见图2，STA确定第一无线帧，并将第一无线帧发送至AP；其中，所述第一无线帧包括R-TWT调整信息，所述R-TWT调整信息指示所述 STA对所述R-TWT的服务周期SP的调整操作。
可选地，在本公开实施例中，AP和STA可以为支持多连接的设备，例如，可以被分别表示为AP MLD和non-AP MLD；AP MLD可以表示支持多连接通信功能的接入点，non-AP MLD可以表示支持多连接通信功能的站点。
具体地，如图1中所示，该方法可以包括以下步骤：
步骤101，确定第一无线帧；其中，所述第一无线帧包括限制目标唤醒时间R-TWT调整信息(R-TWT Adjustment；R-TWT调整信息或称为R-TWT唤醒持续时间调整信息R-TWT Wake Duration Adjustment)，所述R-TWT调整信息指示所述站点设备对所述R-TWT的服务周期SP的调整操作，所述调整操作包括延长R-TWT SP或缩短R-TWT SP。
TWT是一种用于节能的技术，旨在进一步降低Wi-Fi网络功耗。具体地，TWT技术通过使STA和AP协商服务时间(Service Period，SP)，确定STA休眠和唤醒时间和频率；STA在该服务时间保持活跃状态并进行通信，从而可以在服务时间以外的时间进行休眠，以达到节能的目的。此外，TWT技术还可以使AP向多个STA提供更高质量的服务，使竞争或重叠最小化，在降低Wi-Fi网络功耗的同时提高频谱效率。
在低时延传输场景下，较多的应用程序的实时数据流量具有严格的延迟要求，例如，平均延迟或最大延迟的数量级在几毫秒到几十毫秒之间，以及应用程序要求实时数据流量具有极小的抖动以及较强的可靠性。为了进一步确保低时延业务的通信，在TWT的技术基础上，提出了限制型目标唤醒时间(Restricted-Target Wake Time，R-TWT)。R-TWT机制允许AP使用增强的媒体访问保护机制和资源预留机制来提供更可预测的延迟，以将延迟敏感流量与其他类型的流量区分开，使得AP减少最坏情况的延迟和/或减少抖动，提供可靠性更高的服务。
具体地，R-TWT用于服务低时延业务，例如平均延迟小于10毫秒的业务。在R-TWT SP内，只有标识为低时延业务的业务进行通信，其他通信业务在该阶段内暂停或者推迟，从而确保低时延业务的传输。本公开实 施例中，R-TWT的规划设备(例如AP，或称为Scheduling AP)在建立R-TWT时可预设初始的R-TWT SP，而在初始R-TWT SP内，站点设备作为被规划设备(或称为Scheduled STA)可能对初始R-TWT SP进行调整，例如延长R-TWT SP或缩短R-TWT SP，因此，站点设备确定第一无线帧，在第一无线帧中携带R-TWT调整信息(R-TWT Wake Duration Adjustment)，通过所述R-TWT调整信息指示所述站点设备对所述R-TWT的服务周期SP的调整操作，使得其他设备获知所述调整操作。
步骤102，发送所述第一无线帧。
站点设备发送第一无线帧，在第一无线帧中携带R-TWT调整信息，指示站点设备对R-TWT SP的调整操作；所述调整操作包括延长R-TWT SP或缩短R-TWT SP；一方面，在初始R-TWT SP结束后，传输低时延业务的站点设备不能再向其关联的AP发送任何无线帧，若初始R-TWT SP较短，将会导致站点设备和AP间所传输的低时延业务中断，影响通信质量；另一方面，在初始R-TWT SP内，其他非低时延业务不进行通信；若初始R-TWT SP过长，将会导致通信资源的浪费。因此，站点设备通过延长R-TWT SP或缩短R-TWT SP，提升低时延业务的传输质量以及避免通信资源的浪费。
可选地，本公开实施例中，所述第一无线帧包括TWT建立帧(TWT Setup frame)。通常情况下，R-TWT SP作为一种周期性SP，在站点设备调整其时间长度的情况下，若每个SP内，分别发送延长SP或者提前终止SP的消息帧，将会带来额外的信令开销；尤其当SP过短时，额外的信令会导致低时延业务的中断或者暂停；因此，在TWT建立帧中携带所述R-TWT调整信息，避免在每个R-TWT SP分别通知所述调整信息，减少信令开销。
本公开实施例提供了一种通信方法，可选地，所述方法可应用于站点设备，所述方法包括：
在以下情况一至情况三中的至少一种，延长所述R-TWT SP，并将 R-TWT调整信息携带在第一无线帧中，发送所述第一无线帧：

可选地，N可以是正整数，例如1、2等，第一参数值可以设置为1，第一参数值表示AP确认后续仍有低时延业务数据传输；所述第二无线帧可以是多数据子字段设置为1的确认帧、多数据子字段设置为1的块确认帧、多数据子字段设置为1的多站点块确认帧；在AP确认后续仍有低时延业务数据传输时，站点设备主动延长R-TWT SP，避免低时延业务传输中断。
情况二，在所述R-TWT SP结束时未接收到所述R-TWT的规划设备发送的第三无线帧；其中，所述第三无线帧包括确认帧、块确认帧或多站点块确认帧；所述第三无线帧用于标识AP确认接收到站点设备所传输的低时延业务数据，若在所述R-TWT SP结束时未接收到第三无线帧，则可能低时延业务数据未传输完成，此时站点设备主动延长R-TWT SP。
情况三，在所述R-TWT SP结束之前，接收到所述规划设备发送的第四无线帧；其中，所述第四无线帧的QoS Control字段的服务期结束(End of Service Period，EOSP)子字段设置为第二参数值，第二参数值例如为0，表示第四无线帧的服务期尚未结束，此时站点设备主动延长R-TWT SP。

情况四，在所述R-TWT SP结束之前的最后M个帧间隔内，接收到所述R-TWT SP的规划设备发送的第五无线帧；其中，所述第五无线帧包括确认帧、块确认帧或多站点块确认帧，且所述第五无线帧的多数据子字段设置为第三参数值，例如第三参数值设置为0。
可选地，M可以是正整数，例如1、2等，第三参数值设置为0表示AP确认后续不再有低时延业务数据传输；所述第五无线帧可以是多数据子字段设置为0的确认帧、多数据子字段设置为0的块确认帧、多数据子字段设置为0的多站点块确认帧；在AP确认后续不再有低时延业务数据传输时，站点设备主动缩短R-TWT SP，避免R-TWT SP过长，导致通信资源的浪费。
情况五，在所述R-TWT SP结束之前，在预设的R-TWT超时时间内未传输数据或接收数据；即在预设的R-TWT超时时间内，站点设备未接收数据或发送数据，则低时延业务可能已经传输完成，站点设备可主动缩短R-TWT SP。

在站点设备缩短R-TWT SP时，可以根据预设的R-TWT调整时间缩短所述R-TWT SP，例如先设定R-TWT调整时间为5毫秒，在缩短所述R-TWT SP时，可以缩短5毫秒。此外，站点设备还可以提前结束所述R-TWT SP。

本公开实施例提供了一种通信方法，可选地，所述方法可应用于接入点设备，所述接入点设备可以是所述R-TWT SP的规划设备，该方法可以包括以下步骤：
接收第一无线帧；其中，所述第一无线帧包括限制目标唤醒时间R-TWT调整信息，所述R-TWT调整信息指示站点设备对所述R-TWT的服务周期SP的调整操作，所述调整操作包括延长R-TWT SP或缩短R-TWT SP。
可选地，所述方法包括：
发送第六无线帧，所述第六无线帧中包括所述R-TWT超时时间。
可选地，所述第六无线帧为包括受限TWT参数集字段或包括极高吞吐量操作EHT Operation的管理帧。
