摘要： In an embodiment, a source device encodes source information corresponding to a frame, assembles an initial data frame that includes the encoded data blocks, and transmits the initial data frame to a destination device. The destination device decodes the encoded data blocks and assembles a restored version of the initial data frame. The destination device identifies corrupted data blocks and uncorrupted data blocks within the restored version, stores the uncorrupted data blocks, generates a message that identifies the corrupted data blocks, and transmits the message to the source device. In response, the source device encodes source information corresponding to the corrupted data blocks identified in the message, assembles a responsive data frame, and transmits the responsive data frame to the destination device. The destination device produces a corrected data frame from the retransmitted data blocks and the previously-stored uncorrupted data blocks.

摘要： A method for communicating uncompressed HD information includes a transmitter configured to send over wireless channels data-packets and a receiver configured to receive the data-packets from the transmitter. The wireless receiver includes decoders configured to decode the data-packets and an ACK-processor configured to aggregate and send acknowledge signals having an ACK signal for at least one subpacket from the previous packet and ACK signals for all but the at least one subpacket from the current packet. The transmitter may resend a subpacket of the data-packets corresponding to ACK signals in the second status received from the receiver. The new partially delayed ACK mechanism can substantially improve the system throughput for systems with parallel multiple decoders.
摘要翻译：用于传送未压缩HD信息的方法包括被配置为通过无线信道发送数据分组的发射机和被配置为从发射机接收数据分组的接收机。无线接收器包括被配置为对数据分组进行解码的解码器和被配置为聚合并发送具有来自先前分组的至少一个子分组的ACK信号的确认信号的ACK解码器以及来自所述至少一个子分组的除了所述至少一个子分组之外的所有ACK信号当前数据包。发射机可以重新发送对应于从接收机接收的第二状态中的ACK信号的数据分组的子分组。新的部分延迟ACK机制可以显着提高具有并行多个解码器的系统的系统吞吐量。

摘要： A method and system for wireless communication of different information types over a wireless channel, is provided. Information comprising different information types is formed into a composite aggregation of the different information types, and the composite aggregation is transmitted from a sender to a receiver over a wireless channel. A composite acknowledgement (ACK) format is utilized by the receiver to reduce the overhead in low-rate channels.

摘要： In the method, a receiver receives an indication of if the maximum number of sub-packet transmissions for conveying a data packet from a transmitter to the receiver has taken place. If the receiver has not properly received the data packet over a channel when this indication is received, then the receiver sends a non-acknowledgement response that causes the transmitter to re-schedule and re-send the data packet.
摘要翻译：在该方法中，接收机接收是否发生了用于将数据分组从发射机传送到接收机的最大数量的子分组传输的指示。如果在接收到该指示的情况下接收机没有通过信道正确地接收到数据分组，则接收机发送非确认响应，使得发送机重新调度和重发数据分组。

摘要： A network includes a TCP-in-TCP tunnel between a mobile device, which includes a TCP client and a gateway, and a TCP server, which resides in a subnet. Another gateway in the subnet receives and caches TCP packets and acknowledgments (ACKs) from the TCP-in-TCP tunnel. In response to receiving an indication from the TCP server that it has not received a cached TCP packet, the second gateway may resend the packet without relaying the indication to the TCP client, and the first gateway may send a control message instead of a complete TCP packet to the second gateway.

摘要： Embodiments of the invention are directed to methods and systems for providing efficient, scalable and reliable transport of large media files to multiple receivers over digital video broadcast (DVB) standards-based broadcast networks. Transport Reliability is achieved using Forward Error Correction (FEC) and a selective, Negative Acknowledgement (NACK) mechanism over an IP-based unicast feedback path. Out-of-band command and control messages over DVB network are used for initiation and coordination between sender and receivers.

摘要： Access control based on CSMA is favorably carried out with the RTS/CTS method used together. If the RTS/CTS procedure is used together, CTS information is transmitted in response to the reception of RTS information, and data is transmitted in response to the reception of CTS. The CTS transmitting station measures the quality of RTS receive signal, and thereby determines a transmission rate at which it can receive and notifies a station as the destination of CTS. The station as the destination of CTS transmits data in response to CTS information. As the transmission rate for this data, the transmission rate indicated in the RATE field in CTS is applied.
