Embodiments of the present invention provide a data sending method, including: respectively receiving, by a forwarding device by using a first FlexE group and in multiple timeslots included in a first timeslot set, multiple first encoded data blocks generated by a physical coding sublayer; determining, by the forwarding device according to the multiple timeslots included in the first timeslot set and the first FlexE group, a second FlexE group and multiple timeslots included in a second timeslot set; and respectively sending, by the forwarding device, the multiple first encoded data blocks by using the second FlexE group and in the multiple timeslots included in the second timeslot set. According to the data sending method in the embodiments of the present invention, the forwarding device does not need to process the first encoded data blocks in a conventional layer 2 (link layer) or layer 3 (network layer) forwarding mode. Therefore, a processing delay can be reduced, and a transmission delay can be reduced.

Embodiments of the present invention provide an information feedback method. User equipment UE detects downlink transmission data in a received subframe. The UE sends a response message for the downlink transmission data to the access network device, where the response message is sent by the UE on an uplink symbol in a K th subframe after the received subframe, K is the same for any subframe arrangement in a TDD system, and K is a positive integer. The embodiments of the present invention are applied to the TDD system. An ACK or NACK feedback time is reduced, thereby greatly reducing a HARQ delay and meeting a transmission requirement for an ultralow delay.

An avionics switched full-duplex Ethernet communication Arinc 664p7 network (100) includes at least two independent elementary networks (N1, N2). Each elementary network includes one or more end systems (ESI) suitable to act as source end systems for data frames transmitted over the network, and one or more end systems (ES4) suitable to act as destination end systems for such data frames. Each elementary network further includes a switching function block (SW1, SW2) connected between the source (ESI) and destination (ES4) end systems. The Ethernet network is has one of the source (ESI), destination (ES4) end systems and the switching function block (SW1, SW2) includes timers (204) suitable to generate a common piece of timing information to be sent to the other devices of the elementary network in-order to enable the transmission of the data frames over the elementary network by one of the source end systems (ESI).

Apparatus and methods are provided for controlling synchronous and asynchronous communications in an avionic network. The method (200) includes receiving (205) one or more asynchronous messages and one or more synchronous messages, allocating (210) each of the synchronous messages to a corresponding predetermined time slot while producing an unoccupied portion in at least one of the predetermined time slots, and allocating (215) the asynchronous messages to one or more of the unoccupied portions of the predetermined time slots.

An OFDM based multiple access system provides strong persistence against selective frequency fading and further provides suppression of inter-cell interference by using cell differentiating scrambling codes. Thus, the OFDM system maximizes frequency reuse rate. The present invention includes an OFDM modulator (30) frequency-division-multiplexing data to be transmitted, a code division unit (32) multiplexing the frequency-division-multiplexing data with a prescribed code, and an RF end (33) converting the data multiplexed by the code division unit to a radio frequency signal to tansmit. Accordingly, the present invention raises the degree of freedom (frequency division, time division, code division) of system implementation in the multiple access system. The OFDM system includes the scambling of the downlink data by different scrambling codes by a cell unit for base stations within at least two neighboring cells to identify the respective cells and transmitting the spread downlink data.
