下面将结合图1至图7来讨论根据本公开的实施例的用于无线通信的示例过程。
图1示出了本公开的示例实施例可以在其中实施的示例网络环境100的示意图。如图1所示，网络环境100可以包括能够实现无线通信传输的设备110和120。在一些实施例中，设备110可以被称作无线通信中的发送设备110，而设备120可以被称作无线通信中的接收设备120。应当理解，设备110和120之间的角色也可以相互交换，即将设备120用作无线通信中的发送设备，而将设备110用作无线通信中的接收设备。在下文中，为了方便描述，将设备110视作无线通信中的发送设备110，以及将设备120视作无线通信中的接收设备120。
在网络环境100中，设备110和设备120可以包括但不限于移动电话、蜂窝电话、智能 电话、平板电脑、平板手机、计算机、便携式计算机、台式计算机、个人数字助理(PDA)、监视器、计算机监视器、电视、调谐器、娱乐单元、导航设备、通信设备、固定位置数据单元、移动位置数据单元、收音机、卫星收音机、音乐播放器、数字音乐播放器、便携式音乐播放器、数字视频播放器、视频播放器、数字视频光盘(DVD)播放器、便携式数字视频播放器或其他任何可以支持无线通信的适当的设备。
应当理解，网络环境100仅用于示例性目的，而不暗示对于本公开的范围的任何限制。本公开的实施例还可以被体现在其他网络环境或架构中。另外，还应当理解，网络环境100还可以包括用于实现通信连接、数据传输等目的的其他元件或实体。为了简化描述，在图1中并未示出这些元件或实体，但不意味着本公开的实施例不具备它们。
根据本公开的实施例的网络环境100可以是遵循当前已知或将来要开发的任何协议的无线网络，包括但不限于，窄带物联网系统(Narrow Band-Internet of Things，NB-IoT)、全球移动通信系统(Global System for Mobile Communications，GSM)、增强型数据速率GSM演进系统(Enhanced Data rate for GSM Evolution，EDGE)、宽带码分多址系统(Wideband Code Division Multiple Access，WCDMA)、码分多址2000系统(Code Division Multiple Access，CDMA2000)、时分同步码分多址系统(Time Division-Synchronization Code Division Multiple Access，TD-SCDMA)，长期演进系统(Long Term Evolution，LTE)以及5G移动通信系统的三大应用场景eMBB、URLLC和eMTC。
如上文已经提到的，在无线通信系统中，由于无线信道的突变以及多径衰落等特性，数据的传输通常不是完全可靠的。因此针对数据的传输需要系统通过反馈确认帧进行确认。例如，该反馈确认帧可以包括媒体访问控制(Medium Access Control，MAC)层的确认(Acknowledge，ACK)，MAC层的块确认(Block Ack)以及物理(Physical，PHY)层的ACK。
在基于802.11abg协议的移动热点(Wi-Fi)通信系统中，发送端发送的MAC帧通常是单个的媒体访问控制服务数据单元(MAC Service Data Unit，MSDU)类型的MAC帧。发送端每发送这样的一个MAC帧都需要一个ACK帧来对此MAC帧的传输进行确认。
在上述方案中，由于只能对单个MSDU MAC帧进行确认，而单MSDU一般由于以太MTU的限制只能在1500比特左右，整体系统的MAC层效率太差，即使可以提供物理层传输速率，系统吞吐量也没法做到很大提升。
在基于802.11n、802.11ac、802.11ax等协议的Wi-Fi通信系统中，发送端发送的MAC帧通常是聚合的媒体访问控制协议数据单元(Aggregate MAC Protocol Data Unit,AMPDU)类型的MAC帧，其可以由单个或多个媒体访问控制协议数据单元(MAC Protocol Data Unit，MPDU)聚合而成。每个MPDU则可以由单个或多个MSDU组成。接收端针对每个MAC AMPDU聚合帧回复BA帧进行确认。
在上述方案中，802.11n和802.11ac协议BA确认窗口确认的数据帧固定为64比特。虽然对于802.11ax BA的确认窗口增加了256比特的支持，但也还是只支持64比特和256比特两种，且64比特和256比特是在BA会话建立阶段就确认了，在BA会话建立后不会动态改变。在这种情况下，确认窗口的调整粒度过于粗糙，且无法更细的调整BA确认窗口的大小。另外一个问题是BA反馈信息不能动态调整，如果初始阶段BA使用了较大的确认窗口，即便在后续数据量来包变少的情况下，还是使用同样的大确认窗口，而实际只能确认较少的聚合帧，会导致系统的效率大大降低。
此外，在长期演进(Long Term Evolution，LTE)以及新无线电(New Radio,NR)等无线通信系统中，在发送端，MAC层帧经过聚合后在PHY层只看到整体的传输块帧(Transport Block Frame,TB FRAME)传输。PHY层对整个TB FRAME或对TB FRAME划分码块组(Code Block Group,CBG)传输块来传输进行ACK确认。
这种方案下的确认帧的传输开销较小。然而，接收端只能对整个TB帧或CBG传输块进行确认，一旦遇到TB或CBG传输块很大的情况下，传输误包率将会上升，进而可能导致重传效率较差。此外，该方案需配合混合自动重传(Hybrid Automatic Repeat Request，HARQ)重传进行重传合并才能有比较高的物理层传输成功率，但HARQ实现复杂度高，成本较高。
因此，期望实现一种能够逐帧并细粒度的动态调整BA帧确认窗口的大小的方案，从而一方面提高系统效率，另一方面保证较低的传输误包率。
因此，本公开的实施例提出一种用于无线通信的方法。在该方法中，接收设备响应于聚合帧的接收，生成反馈帧。该反馈帧包括第一指示信息和第二指示信息。第一指示信息指示用于传输所述反馈帧的反馈窗口的窗口大小，其可以根据与所述反馈窗口相关联的配置信息来确定。第二指示信息指示所述接收设备接收所述聚合帧的接收状态信息。接收设备在反馈窗口上向发送设备发送反馈帧。通过本公开提出的基于块确认的反馈帧的帧结构，可以实现精细粒度的用于反馈帧的反馈窗口的动态调节。
现在参考图2。图2示出了根据本公开的示例实施例的用于无线通信的过程200的信令交互图。该示例交互过程200可以涉及如图1中所示的发送设备110和接收设备120。出于讨论的目的，下面将参考图1来描述过程200，但是应当理解，该过程同样适用于其他通信场景和设备。
如图2所示，在205，发送设备110向接收设备120发送聚合帧。在一些实施例中，该聚合帧可以是MAC AMPDU。应当理解，该聚合帧也可以包括本公开的实施例所涉及的通信协议框架下的其他聚合帧。
在210，接收设备120针对聚合帧的接收状态生成反馈帧。在一些实施例中，该反馈帧可以是BA帧。
反馈帧可以包括第一指示信息。该第一指示信息可以指示用于传输该反馈帧的反馈窗口的窗口大小。接收设备120可以通过与反馈窗口相关联的配置信息来确定反馈窗口的窗口大小。
在一些实施例中，第一指示信息可以包括与反馈窗口的窗口大小所能承载的数据量相对应的比特值。例如，能在反馈窗口上被传输的所述反馈帧的数据量可以被设定为8，16，32，64，128，256或512比特，其可以分别对应于1-7的比特值。该第一指示信息在反馈帧中所占用的字段长度可以为4bit。
反馈帧还可以包括第二指示信息。在一些实施例中，该第二指示信息可以指示接收设备120接收该聚合帧的接收状态信息。该接收状态信息可以被包括在第二指示信息中所所包括的长度可变的内容字段中。
在一些实施例中，接收设备120例如可以通过下行的调度信令来动态的获取或确定与反馈窗口相关联的配置信息。
在一些实施例中，发送设备例如可以通过所发送的反馈帧来生成调度信令。该调度信令例如可以是下行控制信息(Downlink Control Information，DCI)。发送设备例如可以将与反馈窗口相关联的配置信息指示在DCI中的与反馈帧的反馈类型相关联的指示字段中。发送设备 可以将所生成的调度信令发送至接收设备120。
接收设备120可以接收该DCI。接收设备120可以从该DCI获取与反馈帧的反馈类型相关联的指示字段，并进而通过该指示字段来确定与反馈窗口相关联的配置信息。DCI中的与反馈帧的反馈类型相关联的指示字段的一个示例性实施例可以在下文中示出。
表1：与反馈帧的反馈类型相关联的指示字段
Figure PCTCN2022082254-appb-000001
如表1所示，该指示字段可以是DCI中的ACK type字段，其长度可以被设定为4bit。该指示字段的内容可以对应于反馈帧中的第一指示信息。
如图2所示，在215，在生成反馈帧之后，接收设备120可以在所确定的反馈窗口上向发送设备110发送该反馈帧。
以下结合图3进一步阐述根据本公开的实施例所提出的反馈帧格式的实例。如图3所示，反馈帧300可以包括控制字段(BA Control)310和内容字段(BA INFO)320。该第一指示信息可以被指示在控制字段310中，而第二指示信息可以被指示在内容字段320中。
在一些实施例中，BA Control字段的格式一个示例性实施例可以在下文中示出。

根据在上文中所描述的本公开的示例性实施例，实现了一种基于BA的反馈帧的帧结构，可以实现精细粒度的用于反馈帧的反馈窗口的动态调节。以此方式，可以显著提高系统效率，并且同时保证较低的传输误包率。
