Disclosed is a method for frame acknowledgement, the method comprising: upon completion of downlink service data scheduling and resource allocation, allocating feedback resources in the uplink of the present physical frame; or, upon comple - tion of the uplink service data scheduling and resource allocation, allocating feedback resources in the downlink of the next frame for sending a Group ACK response; according to the allocated feedback resources, encapsulating the corresponding control signaling used for indicating feedback resource allocation; sending the feedback resource control signaling in a control channel of the physical frame. Also disclosed is a device for frame acknowledgement. In a centralized wireless communication system having an uplink and downlink frame structure, the method and device of the present invention realize data packet sending and acknowledgement in the form of MAC frames at the MAC level, and achieve the least acknowledgement delay and high reliability by providing group acknowledgement with minimum complexity, thus facilitating resource scheduling and retransmission scheduling.


In the present invention, before data transmission, a connection, between a requesting end and a destination end, identified by a traffic flow identifier (FID) is established or modified through traffic flow management. Therefore, when the requesting end and the destination end perform data transmission on the traffic flow, the FID alone can sufficiently serve as the identifier, so as to save the need of carrying the destination end identifier in each exchanged data packet, thereby simplifying the operation.

A method and apparatus for transmitting and receiving data are disclosed. The method for transmitting data, comprising encapsulating one or multiple media access control protocol data units (MPDU) as a group media access control protocol data unit (G-MPDU) based on a length of the group media access control protocol data unit G-MPDU; fragmenting a current MPDU according to a residual length to obtain a fragmented MPDU when the residual length is insufficient to encapsulate the current MPDU; encapsulating the fragmented MPDU to the G-MPDU; and transmitting the encapsulated G-MPDU. The method ensures a high data transmission rate and does not wasting excess time to execute the fragmentation processing. The method also ensures a high resource utilization rate, utilizing fully the remaining length of the data unit.
