A first communication device receives an aggregated data unit from a second communication device. The aggregated data unit aggregates (i) one or more sets of multiple data units, each set of multiple data units to be acknowledged by a respective block acknowledgement and (ii) one or more single data units, each single data unit to be acknowledged by a respective single acknowledgement. The first communication device generates a block acknowledgment frame that includes (i) block acknowledgement information to acknowledge the one or more sets of multiple data units, and (ii) single acknowledgment information to acknowledge the one or more single data units, where the block acknowledgement frame omits an indication that the block acknowledgement frame includes the single acknowledgement information. The first communication device causes the block acknowledgement frame to be transmitted to the second communication device.

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.

Systems, methods, and apparatus for reporting a Downlink Data Delivery Status (DDDS) are disclosed herein. An example method includes a network node generating a DDDS frame including an indicator that a highest transmitted Packet Data Convergence Protocol (PDCP) Packet Data Unit (PDU) sequence number is present in the DDDS frame, an indicator that a highest successfully delivered PDCP PDU sequence number delivered is present in the DDDS frame, a desired buffer size for a data bearer, the highest transmitted PDCP PDU sequence number, and the highest successfully delivered PDCP PDU sequence number. The network node provides the DDDS frame to a second network node.

A method and a device for transmitting data in a wireless LAN system are presented. Particularly, a transmission STA transmits information about a preamble puncturing pattern to a reception STA. The transmission STA transmits data to the reception STA through a 320 MHz band on the basis of the preamble puncturing pattern. The preamble puncturing pattern is determined on the basis of a first bandwidth unit in which a CCA is performed and a second bandwidth unit in which user specific information is repeated. At least one 20 MHz subchannel is punctured in the 320 MHz band on the basis of the preamble puncturing pattern.

Techniques are provided for managing cross-layer transport awareness of a user space protocol stack. A protocol layer of a user space protocol stack within a user space application operated in a user space of a first device can receive a batch of packets of a data flow from a corresponding protocol layer operated by a second device. The protocol layer can process a group of packets in the batch of packets to generate a set of acknowledgement packets of the data flow, and process an additional packet in the batch of packets to generate an additional acknowledgement packet of the data flow. The additional acknowledgement packet is indicated to supersede the set of acknowledgement packets. The protocol layer can transmit the additional acknowledgement packet to the second device to indicate that both the group of packets and the additional packet have been received by the first device.

Wireless communications systems and methods related to hybrid automatic repeat request (HARQ) history feedbacks are provided. A user equipment (UE) receives one or more data blocks of a plurality of data blocks, each of the one or more data blocks received in one of a plurality of transmission occasions. The UE transmits an individual feedback for each of the one or more data blocks indicating whether the data block is received successfully. The UE transmits a feedback history report for one or more transmission occasions of the plurality of transmission occasions.

Examples of block acknowledgement negotiations are described. In an example, a request to establish a BA session is sent by a first computing device (first device) to a second computing device (second device). A timer for receipt of a response to the request is initialized. A BA successful response is received by the first device after the timer has timed out. A request to terminate the BA session is sent by the first device to the second device. After sending the request to terminate the BA session, BA negotiation is reinitiated by the first device based on an updated inactivity timer, so that there are greater chances of successfully establishing a BA session. In an example, if the second device ignores the request to terminate the BA session then it sends a BA reject response to the first device. After receiving the BA reject response, the first device waits for the inactivity timer before reinitiating BA negotiations, so that the second device clears its states thereby increasing chances of successful BA renegotiations.

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.

Aspects of the present disclosure provide various hybrid automatic repeat request (HARQ) retransmission indication schemes used in a HARQ retransmission process. The HARQ retransmission indication can implicitly or explicitly indicate which part of a transport block (TB), code block group(s), or code block(s) is/are being retransmitted so that the receiver can associate the retransmitted TB, code block group(s), code block(s) with the correct prior reception, for example, for HARQ combining purposes.

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.
