Receiver, transmitter, communication network, data signal and method improving a retransmission process in a communication network

A receiver is described which receives data from a transmitter. The data is included in a data block which includes at least one code block, and the code block has a plurality of parts. A first part of the code block is used for estimating a decodability of the code block at the receiver. The first part of the code block is arranged in the data block ahead of the remaining one or more parts of the code block. The receiver estimates, prior to receiving the entire data block, the decodability of the code block using the first part of the code block.

Wireless communication method using fragmentation and wireless communication terminal using same

Provided is a wireless communication terminal that communicates wirelessly. The terminal includes: a transceiver; and a processor. The processor is configured to transmit first information on a fragmentation level to be used for data to be transmitted to a recipient by using the transceiver in an add Block ACK (ADDBA) setup procedure.

Method and devices for multiple transmit receive point cooperation for reliable communication

Embodiments of the present application pertain to control information for scheduling a transmission resource for downlink and uplink communications between one or more TRP and one or more UE. One Physical Downlink Control Channel (PDCCH) for DL control information transmission is assumed to carry at least one assignment or scheduling information block for at least one Physical Downlink Shared Channel (PDSCH) for DL data transmission or for at least one Physical Uplink Shared Channel (PUSCH) for UL data transmission. Embodiments of the present application provide methods of providing configuration information that can be used by a user equipment (UE) to determine transmission mode for the PDSCH and PUSCH as well as information to determine where to monitor for the PDSCH, PUSCH and PUCCH information.

20170346742 · 2017-11-30 ·

A method for communication includes establishing, using an end-to-end reliable transport context, a channel for exchange of data packets over a network between a first network interface controller (NIC) of a first computing node on the network and a second NIC of a second computing node on the network. The first NIC accepts first and second work items for execution on behalf of different, first and second sender processes, respectively, that are running on the first computing node. The first and second work items are executed by transmitting over the network from the first NIC to the second NIC, using the end-to-end reliable transport context, first and second messages directed to different, first and second receiver process running on the second computing node, using the same end-to-end reliable transport context. The second message is sent before receiving from the second NIC any acknowledgment of the first message.

COMMUNICATION DEVICE AND COMMUNICATION METHOD

To provide a communication device for transmitting a common response signal including data acquisition success/failure information of a plurality of links.

A communication device that performs wireless communication using a plurality of links includes a common data processing unit that includes a common storage unit of a cache type storing success/failure of acquisition of packets received on the plurality of links, and that performs common data processing on packets received on individual links, and a control unit that controls transmission of a response signal to the packets received. The control unit generates a common response signal including acquisition success/failure information received on the plurality of links on the basis of acquisition success/failure information held in the common storage unit.

FEEDBACK AND TRAFFIC DIFFERENTIATION IN SIDELINK RELAYS

A user device, UE, for a wireless communication network, acts as a relaying entity so as to provide functionality to support connectivity between a transmitting entity and one or more receiving entities of the wireless communication network. Responsive to receiving a transmission from the transmitting entity and to relaying the transmission towards the receiving entity, the UE is to transmit a feedback to the transmitting entity, the feedback indicating a successful and/or non-successful receipt of the transmission at the receiving entity.

CODE BLOCK GROUPING AND FEEDBACK THAT SUPPORT EFFICIENT RETRANSMISSIONS

Methods, systems, and devices for wireless communication are described. A wireless device may transmit feedback, such as hybrid automatic repeat request (HARD) feedback for groups of code blocks rather than for an entire transport block or individual code blocks. The wireless device may transmit an acknowledgement (ACK) or negative-acknowledgement (NACK) to provide feedback for each code block group of a set of code block groups. An ACK may indicate that code blocks in a code block group were successfully decoded, and a NACK may indicate that at least one code block in a code block group was not successfully decoded. Wireless devices may support several techniques for grouping code blocks for feedback reporting to allow for efficient retransmissions and limited overhead. Different grouping schemes may be employed depending on system constraints, device capability, link conditions, or the like.

METHOD FOR TRANSMITTING AND RECEIVING MULTIPLE USER BLOCK ACKNOWLEDGEMENT FRAME IN WIRELESS LAN SYSTEM, AND APPARATUS THEREFOR
20170310448 · 2017-10-26 · ·

The present specification relates to a method of an access point (AP) transmitting a block acknowledgement (ACK) signal with respect to transmission data of a plurality of stations (STA) in a wireless LAN (WLAN) system, and an apparatus therefor. To this end, an AP transmits a multi-STA BA frame with respect to data received from the plurality of STA, wherein the multi-STA BA frame includes a MAC header field, a BA control field and a BA information field. In this regard, the BA information field may include: AID information with respect to one or more STA to which ACK/NACK is transmitted from the plurality of STA; and an individual information field including BA indicator information that indicates whether the BA information field includes one or more of a block ACK bitmap sub-field and a starting sequence control sub-field.
