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.

A user equipment that is provided in a wireless communication system including a base station and the user equipment includes an acquisition unit that acquires information indicating a resource position where a downlink data channel is mapped or a resource position where an uplink data channel is mapped in a radio frame and a timing when an HARQ response to downlink data is transmitted from the user equipment or a timing when an HARQ response to uplink data is received from the base station and a communication unit that transmits an HARQ response to downlink data received by the downlink data channel at a timing when the HARQ response to the downlink data is transmitted and receives an HARQ response to data transmitted by the uplink data channel or retransmission data scheduling information at a timing when the HARQ response to the uplink data is received.

A method performed by a terminal in a communication system is provided. The method includes identifying a first physical downlink shared channel (PDSCH) scheduled by a physical downlink control channel (PDCCH), and a second PDSCH without a corresponding PDCCH; identifying that the first PDSCH and the second PDSCH are overlapped in time; and decoding the first PDSCH on a basis that the PDCCH scheduling the first PDSCH ends at least 14 symbols before the starting symbol of the second PDSCH.

The present disclosure provides a method and device in a node for wireless communications. A first node receives N signaling groups in M time-frequency resource sets, and transmits a first information block in a first time-frequency resource block. The first information block comprises HARQ-ACKs associated with the N signaling groups; a first signaling group comprises a last signaling in the N signaling groups, the first signaling group is one of the N signaling groups, the N signaling groups are respectively used to determine N reference times, and a first reference time is one of the N reference times determined by the first signaling group; a target signaling group is used to determine the first time-frequency resource block, the target signaling is one of the N signaling groups, N is a positive integer greater than 1.

Provided are an information generation method, a device, and a storage medium. The method includes: receiving a DCI sent by a second communication node, where the DCI is used for scheduling at least one PDSCH; and generating a corresponding feedback codebook according to a C-DAI value and a T-DAI value which are contained in a DAI indicator field in the DCI.

Techniques and apparatuses are described for user equipment-coordination set, UECS, hybrid automatic repeat request, HARQ, that establish a HARQ timeline that is specific to the capabilities of a respective UECS. Compared to a single user equipment, UE, the HARQ timeline for a UECS depends on a number of factors, such as the joint processing capability in the UECS, latency of communication over a local wireless network between the UEs in the UECS, or the like. Based on its capabilities, the UECS can request uplink and/or downlink processing delay times or a UECS-specific HARQ timeline from a base station. The base station grants the uplink and/or downlink processing delay times or the UECS-specific HARQ timeline to the UECS in a layer-1, layer-2, or a layer-3 control message. The use of a UECS-specific HARQ timeline increases the reliability of HARQ signaling for uplink and downlink communication between the UECS and a base station.

The present disclosure describes methods, system, and devices for configuring hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback for physical downlink shared channel (PDSCH) transmission. The method includes receiving, by a user equipment (UE), a radio resource control (RRC) parameter to configure a one-shot HARQ-ACK feedback mode; and receiving, by the UE, a first downlink control information (DCI) comprising a first K, the first DCI corresponding to a first PDSCH. The method includes receiving, by the UE, a second DCI comprising a second K with an applicable value and an one-shot request field with a positive value, the second DCI corresponding to a second PDSCH; and transmitting, by the UE, a one-shot HARQ-ACK feedback according to a preset rule.

The present disclosure relates to a communication technique for merging, with an IoT technology, a 5G communication system for supporting a higher data transmission rate than a 4G system, and a system therefor. The present disclosure can be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail business, security-and safety-related services, and the like) on the basis of a 5G communication technology and an IoT-related technology. The present disclosure discloses a method and apparatus for transmitting and receiving downlink grant-free-based data.

An example method for wireless communication at a first user equipment (UE) may include receiving at least a first sidelink transmission from a second UE, wherein at least a second sidelink transmission from a third UE is scheduled contemporaneously with at least the first sidelink transmission from the second UE. The method may also include transmitting an indication in a transmission occasion to at least one of the second UE or the third UE based at least in part on a prioritization of information for the transmission occasion, wherein the indication indicates that at least the first sidelink transmission from the second UE is scheduled contemporaneously with at least the second sidelink transmission from at least the third UE.

This application provide a resource indication method and a related device. According to the method provided in this application, a terminal device can send a HARQ-ACK on a PUCCH resource in at least one sub-slot. The resource indication method may be applied to the terminal device. The method may include: The terminal device may receive DCI from a network device, where the DCI indicates a slot used by the terminal device to transmit a HARQ-ACK. After receiving the DCI, the terminal device may send the HARQ-ACK on a PUCCH resource in at least one sub-slot of the slot indicated by the DCI. The slot includes at least two sub-slots. In other words, the terminal device may send the HARQ-ACK on a PUCCH resource in one sub-slot of the slot, or may send the HARQ-ACK on a PUCCH resource in a plurality of sub-slots of the slot.
