The invention discloses a method (700) for a cellular system (100), in which traffic can be exchanged between first (110, 120) and second (110, 120) transceivers. The traffic is sent in data units, each of which is given an identifier, and which data units may be divided into segments. A receiving transceiver (110, 120) may send status information in data frames or data units (200, 300) about properly received, partially received, or non-received data units to a sending transceiver, i.e. the transceiver from which the data was sent. In the case (705) of partially or non-received data units, the status information includes (710) information about whether the data unit or units were non-received or partially received, and in the case of one or more partially received data units, which (715) parts of those data units that were not received.

Embodiments include systems and methods for communicating information in a physical uplink control channel (PUCCH) message. A processor of a wireless device may configure a PUCCH message to include an uplink message in a short data field. The processor may send the PUCCH message including the short data field to convey the uplink message to a communication network. In some embodiments, the processor may receive data from a second wireless device in a downlink channel, and may generate an acknowledgement message responsive to the received data. The processor may configure the short data field to include the acknowledgement message, and may send the PUCCH message including the short data field that includes the acknowledgement message to acknowledge the received data.

A method for use in a cellular communications system in which system traffic can be exchanged between transceivers comprises receiving traffic from a second transceiver at a first transceiver. The traffic includes data units that are each associated with an identifier. The data units are also divided into segments. The method additionally includes sending status information from the first transceiver to the second transceiver. The status information pertains to one or more data units transmitted by the second transceiver. Additionally, sending the status information includes, for non-received and partially received data units, sending information indicating the data units were non-received or partially received and, for partially received data units, sending information indicating which parts of the data units were not received.

A method of retransmitting a multicast message through a unicast channel in a virtual distributed storage system comprising a cluster of nodes that includes a master node and a set of agent nodes is provided. Each node maintains a copy of a directory of the virtual distributed storage system. The master node multicasts messages to the agent node through a multicast channel to update the directory. The method determines that a particular message to update the directory exceeds a maximum size limit for transmit to the agent nodes through the multicast channel. The method multicasts a retransmission trigger message from the master node to each agent node. The method receives a retransmission request message at the master node from each of the agent nodes through a unicast channel. The method sends the particular message to update the directory from the master node to each agent node through the unicast channel.

A method performed by a first network node, for transmitting a RLC UM, PDU, to a second network node is provided. The first network node and second network node operate in a wireless communications network. When detected that the RLC UM PDU has failed to be transmitted over a first channel, the first network node decides to redirect the RLC UM PDU to be transmitted over a second channel. The first network node divides the RLC UM PDU into two or more re-segmented RLC UM PDUs. The first network node then transmits the re-segmented RLC UM PDUs to the second network node over the second channel. Each re-segmented RLC UM PDU comprises the following indications: (a) that the re-segmented RLC UM PDU is re-segmented, (b) an order indicator related to the re-segmented RLC UM PDU, and (c) whether or not the re-segmented RLC UM PDU is a last re-segmented RLC UM PDU out of the two or more re-segmented RLC UM PDUs.

A high throughput communication apparatus which provides low frame error rates (FER). Error checking encoder and decoders which each comprise a plurality of short blocklength error checking encoders or decoders, respectively, in parallel, coupled through common incremental redundancy. Short-blocklength codes are utilized to achieve communication capacity with incremental redundancy. The system can transmit and decode a large number of short-blocklength codewords in parallel, while it delivers incremental redundancy, without feedback, only to the decoders that need incremental redundancy.
