Abstract: One feature provides a Block Acknowledgement Retransmission Policy (BARP) frame that permits a transmitter to define a retransmission policy on a per-frame basis for frames transmitted in a block of frames. A block acknowledgement retransmission policy (BARP) frame is generated by a transmitter that individually identifies a retransmission policy for each frame in a block of frames. The BARP frame is then transmitted to a receiver, allowing the receiver to know which frames within a block of frames will be retransmitted and which frames will not be retransmitted.

Abstract translation: 一个特征提供了块确认重传策略（BARP）帧，其允许发射机以帧为单位在帧中发送的帧定义重传策略。 块确认重传策略（BARP）帧由单独识别帧块中每帧的重传策略的发射机生成。 然后将BARP帧发送到接收机，允许接收机知道帧块内的哪些帧将被重传，哪些帧将不被重发。

Abstract: An application service provider provides wireless access to a packetized data network, such as the Internet. The application service provider includes a server computer. The server computer is connected to the network, which is at least in part a wired network. The wired network is connected to a cellular wireless communications system. Data is communicated over the network, both wired and wireless, via OSI models, for example, according to TCP/IP protocols or specialized variants. A wireless device, such as a modern-equipped laptop computer or personal digital assistant, a web-enabled telephone, or the like, is communicatively connected to the cellular wireless communications system. The application service provider can maintain a website, including targeted content, on the server computer for access by the wireless device.

Abstract: Method and arrangement in a terminal for receiving data packets from a base station and providing feedback to the base station. The feedback concerns the reception status of the received data packets and may comprise an ACK/NAK. The method comprises receiving and decoding data packets from the base station in a sub-frame. It is further established whether any data packet within the received subframe is not correctly received and detected whether any subframe, expected to be received, has been missed. Further, acknowledgement information ACK/NAK is generated, a scrambling code selected with which the ACK/NAK is scrambled. The scrambled ACK/NAK is then sent to the base station, concerning the reception status of the data packets within the received subframes.

Abstract: In a network environment such as a wireless packet network, a source node transmits a data stream, e.g., a stream of media packets to a plurality of sink nodes, including the source node transmitting a first data stream of unicast packets addressed to at least a first one of the sink nodes, while other ones of said sink nodes receive while in promiscuous mode traffic on the network including the data stream. Individual ones of the other sink nodes, upon ascertaining that there are packets of the stream that were not received, transmit a re-transmission request to the source node so that the source node can take corrective action, and so all the sink nodes can receive the data stream, even though sent as unicast addressed to fewer than all the sink nodes.

Abstract: This innovation relates to systems and methods for transmission of protocol data units, and more particularly to processing polling requests from a radio link control peer. A radio link control transmitter can poll a receiver to obtain a report regarding the status of a set of data packets, and the polls can be sent in-band with a data packet. The receiver can determine to wait before sending the status report based on one or more characteristics of the received data packets.

Abstract: Dropped packets are recovered in a link layer of a Data Center Ethernet (DCE) network. Data packets for transmission are stored in a replay buffer. Each data packet includes a header having a field including data indicating that the data packet is formatted for reliable recovery at the link layer. The data packets are transmitted to a receiver across a link layer in the DCE network. The receiver determines whether a data packet has been dropped. If a data packet has not been dropped, an acknowledgement signal is sent to the transmitter in another data packet across the link layer, indicating that the data packet has been received. If a data packet has been dropped, a non-acknowledgement signal is sent to the transmitter in the other data packet across the link layer, indicating that the data packet has been dropped. In response to receipt of the non-acknowledgement signal or no receipt of an acknowledgement signal after the timeout period, the dropped data packet is retrieved from the replay buffer and is resent to the receiver across the link layer.

Abstract: A transmitting unit combines a slot identifier (SI) and a block identifier (BI) in each header that is transmitted with the data to allow a receiving unit to associate previously received data blocks with retransmissions, or retries, of the same respective data blocks in order to perform bit error detection in accordance with a hybrid or selective ARQ protocol. The receiving unit uses the SI and BI contained in the MHBKs to determine a correspondence between a retried data and a previously transmitted data block.
