Some embodiments of this disclosure include apparatuses and methods for implementing block acknowledgment (BA) operations for multi-link wireless communication networks. For example some embodiments relate to an electronic device including a transceiver and one or more processors communicatively coupled to the transceiver. The one or more processors transmit, using the transceiver and to a second electronic device, a first set of one or more frames on a first link and a second set of one or more frames on a second link. The one or more processors receive, using the transceiver and from the second electronic device, a first block acknowledgment (BA) frame on the first link and a second BA frame on the second link. The one or more processors further determine, based on received first BA frame and the second BA frame, a failed or missing frame of the first set of one or more frames transmitted on the first link.

Enabling a protocol for efficiently and reliably using the NVME protocol over a network, referred to as NVME over Network, or NVMEoN, may include an NVMEoN exchange layer for handling exchanges between initiating and target nodes on a network, a burst transmission protocol that provides guaranteed delivery without duplicate retransmission, and an exchange status block approach to manage state information about exchanges.

A multi-link aggregation transmission method and a related apparatus. The method includes: a receive end receives at least one of a data frame and a BAR frame over a plurality of links between the receive end and a transmit end, where the plurality of links includes a first link. The receive end receives a block acknowledgment request BAR frame over the first link, where the BAR frame carries SSN_1 corresponding to the first link. The receive end adjusts, based on SSNs corresponding to all the links, a value of a current starting sequence number WinStart of a scoreboard window. The receive end processes, based on the adjusted WinStart, a data frame received over the plurality of links. The receive end can adaptively adjust the WinStart.

There is provided a communication apparatus that complies with an IEEE 802.11 series standard, comprising: data transmitting unit for transmitting data frames each including a data unit to an other communication apparatus a plurality of times continuously; generating unit for generating a Block Ack Request (BAR) frame; BAR transmitting unit for transmitting the BAR frame to the other communication apparatus after transmission of the data frames the plurality of times continuously; and receiving unit for receiving a Block Ack (BA) frame as a response to the BAR frame, wherein the generating unit indicates a sequence number for a data unit in an initial data frame using a predetermined field in the BAR frame, and the predetermined field includes a different field from a Starting Sequence Number field in the BAR frame.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive signaling that indicates whether feedback for each of one or more downlink messages scheduled to be received at the UE is to be single-bit feedback or multi-bit feedback. The UE may monitor for the one or more downlink messages. The UE may generate, based at least in part on the monitoring for the one or more downlink messages, a codebook for reporting the feedback pertaining to each downlink message, the codebook supporting inclusion of both single-bit feedback and multi-bit feedback based at least in part on the signaling. The UE may transmit a feedback message that is based at least in part on the codebook.

Methods, systems, and devices for wireless communication are described. Some wireless communications systems may support codebook structures for multiplexing single-bit feedback and multi-bit feedback in a same uplink feedback message. A user equipment (UE) may receive a first downlink message associated with single-bit feedback and a second downlink message associated with multi-bit feedback. The first downlink message and the second downlink message may have a common uplink transmission opportunity for transmitting feedback pertaining to the downlink messages. The UE may generate a codebook that supports inclusion of both the single-bit feedback and the multi-bit feedback for the first and second downlink messages. The UE may transmit the feedback message during the common uplink transmission opportunity based on the codebook.

Methods, systems, and devices for wireless communication are described. Some wireless communications systems may support configurations for grouping feedback information within a codebook. A user equipment (UE) may support one or more types of feedback. In some cases, the UE may generate subsets of feedback information within the codebook based on each type of feedback, which may increase overhead. To reduce overhead, the UE may receive signaling that indicates a configuration for grouping feedback information within a codebook. The UE may receive downlink messages that may be associated with a same set of uplink resources for transmitting a feedback message. The UE may generate a codebook to include one or more groups of feedback information in accordance with the configuration and based on the downlink messages. The UE may transmit the feedback message based on the codebook and via the set of uplink resources.

A method at a first wireless network element, the method receiving, from a second wireless network element, a plurality of packet data units (PDUs) for a user equipment; transmitting the PDUs to the user equipment (UE); compiling a PDU delivery status report in response to the transmitting of the PDUs; and sending the compiled PDU delivery status report to the second wireless network element.

The disclosure relates to a communication technique for combining a 5G communication system with an IoT technology to support a higher data transmission rate than a 4G system, and a system thereof. The disclosure may be applied to intelligent services (for example, services related to smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail business, security and safety, etc.) based on a 5G communication technology and an IoT-related technology. In an embodiment of the disclosure, a method performed by a terminal in a wireless communication system is provided. The method comprises: receiving, from a base station, a radio resource control (RRC) message including information on an identifier to indicate a secondary cell (Scell), information on at least one bandwidth part (BWP) of the Scell, and information including first information on a first BWP to be used as dormant BWP among the at least one BWP and second information on a second BWP to be activated as non-dormant BWP from dormant BWP; receiving, from the base station, downlink control information (DCI) including a bitmap associated with a BWP activation of the Scell; and activating a BWP identified based on the identifier, the bitmap, and at least one of the first information or the second information. According to the disclosure, via a method by which a new dormant (or hibernation) mode may be operated in units of bandwidth parts (bandwidth part-level), a carrier aggregation technology can be rapidly activated, and a battery of a terminal can be saved.

This disclosure provides systems, methods and apparatus for wireless communication. In one aspect, a multi-transmit-receive point (TRP) approach for hybrid automatic repeat request (HARQ) acknowledgment (ACK) feedback using counter downlink assignment indicators (DAIs) (cDAIs) and total DAIs (tDAIs) is provided. For example, some techniques and apparatuses described herein may provide a joint counting method in which cDAIs and tDAIs are implemented and tracked jointly between the TRPs of a multi-TRP group. This may be useful in the ideal backhaul scenario when the multi-TRP group is jointly scheduled, and may be more robust against errors than a separate counting method. Some techniques and apparatuses described herein may provide a separate counting method, in which cDAIs and tDAIs are implemented and tracked separately by the respective TRPs of a multi-TRP group.
