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 method begins by a dispersed storage (DS) processing module selecting a subset of a set of encoded data slices, wherein the subset of encoded data slices includes less than a decode threshold number of encoded data slices. When a receiving entity is affiliated with a first wireless communication resource, the method continues with the DS processing module outputting the subset of encoded data slices via the first wireless communication resource to the receiving entity, wherein the first wireless communication resource has a first wireless geographic coverage area. When the receiving entity is affiliated with a second wireless communication resource and is located outside of the first wireless geographic coverage area, the method continues with the DS processing module outputting one or more encoded data slices of the set of encoded data slices via the second wireless communication resource to the receiving entity.

A file repair method includes receiving, by a broadcast/multicast service center, a file repair request message sent by user equipment, where the file repair request message includes a Uniform Resource Identifier (URI) corresponding to file data to be repaired and a transmit session identifier of a File Delivery over Unidirectional Transport FLUTE session that transmits the file data. The method further includes determining, according to the transmit session identifier, the FLUTE session that transmits the file data, and determining repair data of the file data according to the FLUTE session that transmits the file data and further according to the URI corresponding to the file data.

A first communication device determines one or more parameters related to a format of a media access control layer (MAC) data unit for an uplink (UL) multi-user (MU) transmission. The format of the MAC data unit for the UL MU transmission is different than a format of a MAC data unit for an UL single user (SU) transmission. The first communication device generates one or more data units that include the one or more parameters. The first communication device transmits the one or more data units to a plurality of second communication devices to inform the plurality of second communication devices of the format of the MAC data unit for UL MU transmissions by the plurality of second communication devices to the first communication device.

The disclosed techniques allow for transmitting a signal stream from a sender to a receiver in an environment including multiple senders and receivers. The technique for the sender decomposes a data stream from the sender into multiple substreams, encodes a substream by a codeword, further superimposes multiple codewords to form a signal stream in an asynchronous manner, and transmits the signal stream to the receiver. A codeword can span over multiple blocks. The receiver receives a first codeword stream from a first sender, receives a second codeword stream from a second sender, the two codeword streams may be received at the same time as one signal, and decodes the first codeword stream and second codeword stream over a sliding window of multiple blocks.

Provided are a method for implementing an automatic retransmission function and a related station. The method includes that a first station sends a first message. The first message carries automatic retransmission enable information. The automatic retransmission enable information is used for instructing that the automatic retransmission function be enabled or disabled.

There is disclosed a method for operating a wireless device, the wireless device being Device-to-Device (D2D) enabled. The method comprises determining feedback on one or more than one communication channel comprising at least one channel of D2D communication and sending different reports on the feedback to different targets.

A method and apparatus are disclosed. The apparatus comprises a wireless transceiver and a processor. The apparatus transmits a data packet via a primary cell and a non-primary cell, the primary cell and the non-primary cell, wherein the data packet is sent via the primary cell and the non-primary cell over an enhanced uplink (EU) channel. On a condition that the transmitted data packet is not successfully decoded by the primary cell and also not successfully decoded by the non-primary cell, the apparatus receives a negative acknowledgement (NACK) signal from the primary cell and not receiving the NACK signal from the non-primary cell and retransmits the data packet in response to receiving the NACK signal from the primary cell even though the NACK signal was not received from the non-primary cell.

Hybrid ARQ is employed in a multi-carrier communication system for retransmission of erroneous packets by taking advantage of time/frequency/space diversity and by combining ARQ functions at physical layer and MAC layers, making the multi-carrier system more robust in a high packet-error environment.

The apparatus of the wireless communication may include a first wireless device configured to transmit sidelink control information (SCI) reserving periodic resources for an initial transmission and aperiodic resources for one or more retransmissions over a sidelink, transmit the initial transmission using the periodic resources, and transmit the one or more retransmissions using the aperiodic resources. The apparatus of wireless communication may also include a second wireless device may be configured to receive the SCI indicating the set of resources for the sidelink transmission from the first wireless device, determine a first resource in the set of resources is periodically reserved, and determine one or more remaining resources in the set of resources is aperiodically reserved.
