An apparatus for wireless communication includes a transmitter and a receiver. The receiver is configured to receive a first code block (CB) that is associated with a code block group (CBG) and that is included in a transport block (TB). The receiver is further configured to receive a second CB that is associated with the CBG and that is included in the TB. The first CB is distinct from the second CB. The second CB includes at least a first bit that is associated with the first CB.

Examples described herein relate to offload reliable transport management to a network interface device and store packets to be resent, based on received packet receipt acknowledgements (ACKs), into one or more kernel space queues that are also accessible in user space.

A system may include primary and secondary integrated circuits. The primary integrated circuit may receive a first subset of data packets associated with a first set of sequence numbers. The secondary integrated circuit may receive a second subset of data packets associated with a second set of sequence numbers. The primary integrated circuit is configured to manage the first set of sequence numbers and the second set of sequence numbers on behalf of the secondary integrated circuit and for the system.

A method and apparatus for switching between unicast and multicast in a wireless communication system is provided. A DU of a RAN node provides the MBS by using a first transmission to the wireless device. A DU of a RAN node receives, from the wireless device, feedback information in response to the provided MBS. A DU of a RAN node transmits, to a central unit (CU) of the RAN node, a first switching message based on the received feedback information. A DU of a RAN node receives, from the CU, a second switching message to switch the first transmission to the second transmission for the MBS. A DU of a RAN node provides the MBS by using the second transmission to the wireless device.

The present invention relates to a method for operating a first communication node in a wireless local area network (WLAN) supporting a multi-link operation, comprising the steps of: setting a first transmit window size of a first link for transmitting a plurality of frames to a second communication node; transmitting the plurality of frames through the first link; when the state of a channel detected through channel sensing in the second link is an idle state, setting a transmit opportunity (TXOP) in the channel; and when the transmit opportunity is set, performing an agreement with the second communication node on the size of a second transmit window for transmitting the plurality of frames. Therefore, it is possible to improve the performance of a communication system.

A method performed by a network node for transmission of a Packet Data Convergence Protocol, PDCP, Protocol Data Unit, PDU, to a wireless communications device is provided. The network node and the wireless communications device operate in a wireless communications network. The network node arranges (505) a number of PDCP PDUs in a numerical order based on their respective PDCP Sequence Number, SN. The number of PDCP PDUs is taken from a first set of PDCP PDUs comprising one or more first time transmitted PDCP PDUs and from a second set of PDCP PDUs comprising one or more retransmitted PDCP PDUs. The one or more first time transmitted PDCP PDUs and the one or more retransmitted PDCP PDUs are received from a controlling node. The network node transmits (506) the number of the PDCP PDUs in the numerical order to the wireless communications device 120.

Systems and methods for packet payload mapping for robust transmission of data are described. For example, methods may include receiving, using a network interface, packets that each respectively include a primary frame and one or more preceding frames from the sequence of frames of data that are separated from the primary frame in the sequence of frames by a respective multiple of a stride parameter; storing the frames of the packets in a buffer with entries that each hold the primary frame and the one or more preceding frames of a packet; reading a first frame from the buffer as the primary frame from one of the entries; determining that a packet with a primary frame that is a next frame in the sequence has been lost; and, responsive to the determination, reading the next frame from the buffer as a preceding frame from one of the entries.

Methods and apparatuses are provided for generating a protocol data unit (PDU). A method may include transmitting a medium access control (MAC) protocol data unit (PDU) include information associated with one or more logical channels. The MAC PDU to be transmitted may be assembled by determining an amount of information associated with one of the one or more logical channels to be included in the MAC PDU; and multiplexing one or more complete service data units (SDUs) associated with at least the one of the one or more logical channels into the MAC PDU. On a condition that multiplexing an additional SDU associated with the one of the one or more logical channels would exceed the determined amount of information, the one or more complete SDUs may be multiplexed with a segment of the additional SDU associated with the one of the one or more logical channels and a header indicating that the segment is not a last segment of the additional SDU.

A wireless communication apparatus, method or protocol for wireless STAs using CSMA/CA on a wireless local area network (WLAN). A receiver STA receives MSDUs or A-MSDUs which include an expiration time, from a transmitter STA. The receiver STA stores the MSDUs or A-MSDUs with expiration time in its receive reordering buffer of the corresponding high-throughput (HT)-immediate block acknowledgement (Ack) agreement. The receiver STA passes the MSDU or A-MSDU to a next MAC process before an expiration time of the MSDU or A-MSDU. Thus, the percentage of latency sensitive traffic packets being communicated prior to expiration is increased.
