A method of receipt status reporting in a communication device, comprising configuring (S1) said communication device for periodic receipt status reporting by associating a first status report type with a value of a first reporting periodicity parameter and associating a second status report type with a value of second reporting periodicity parameter, said first status report type being different from said second status report type and said first reporting periodicity parameter being different from said second reporting periodicity parameter, and periodically (S2) sending receipt status reports of said first type according to said associated value of said first reporting periodicity parameter and receipt status reports of said second type according to said associated value of said second reporting periodicity parameter.

In an embodiment, a source node assigns a first number to a probe data packet in a probe data flow in a sending sequence, where the first number is used to select a transmission path for the probe data packet. The source node sends the probe data packet in the probe data flow to a destination node at a first sending rate. Each time the source node receives a probe data packet backhauled by the destination node, the source node sends a service data packet in a service data flow, where the service data packet is assigned a second number corresponding to the probe data packet, and the second number is used to select a transmission path for the service data packet.

Some aspects of this disclosure relate to apparatuses and methods for a user equipment (UE) to send a portion of a packet data unit (PDU) to a base station. A radio link control (RLC) layer of the UE generates a PDU and a truncation indicator, where the truncation indicator can indicate a set of truncation points of the PDU. A medium access control (MAC) layer determines whether an uplink transmission size based on an uplink grant is smaller than a first number of bytes included in the PDU. In response to a determination that the uplink transmission size is smaller than the first number of bytes, the MAC layer selects a truncation point from the set of truncation points indicated by the truncation indicator, and remove at least a portion of the PDU to generate a truncated PDU having a second number of bytes smaller than the uplink transmission size.

Disclosed in the invention are a transmission method, a device, a terminal, a base station and a storage medium. The method comprises: the terminal receiving a downlink transmission; and sorting ACK/NACK feedback information of the downlink transmission according to a DAI corresponding to the downlink transmission, to obtain an ACK/NACK sequence to be fed back, and sending same. The DAI performs cumulative counting on the downlink transmission, according to at least the order of a transmitting and receiving node (TRP). Provided is a transmission scheme in which ACK/NACK feedback can be performed in a case where the terminal simultaneously receives two PDSCHs in the same serving cell.

Embodiments of a device, a method, and a system for Block Acknowledgement (Ack) (BA) operations are disclosed. In an embodiment, the device includes a wireless network interface device implemented on one or more integrated circuits (ICs), where the wireless network interface device is configured to negotiate a BA agreement for multiple links, where the BA agreement includes a managed scoreboard context and a managed reorder buffer, and exchange frames according to the BA agreement.

A packet transmission method and an electronic device. In the packet transmission method, a response packet request field is set in a service packet, and a sending device can set a value of a response packet request field in a sent service packet. When the sending device needs a receiving device to send a response packet, the sending device changes a value of a response packet request field in a subsequently sent service packet, to trigger the receiving device to send the response packet to the sending device.

A reception device includes a wireless communicator, a memory, and one or more processors. The processors identify a retransmission candidate of image data on the basis of a sequence number recorded on the memory. The processors calculate an upper limit retransmission number on the basis of a physical rate and a communication rate recorded on the memory. The processors set an allowable retransmission number that is less than or equal to the upper limit retransmission number. The processors transmit a retransmission request for requesting retransmission of as many of the retransmission candidates as the allowable retransmission number to the transmission device in a blanking period by using the wireless communicator when the number of the retransmission candidates identified through the identification processing exceeds the allowable retransmission number.

Apparatuses, methods, and systems are disclosed for consecutive data packet feedback. One method includes receiving a first set of consecutive data packets. The method includes transmitting feedback corresponding to the first set of consecutive data packets, wherein the feedback comprises: an error indication in response each data packet in the first set of consecutive data packets failing to be received correctly; a non-error indication in response to at least one data packet in the first set of consecutive data packets being received correctly; a counter value that indicates a consecutive number of data packet failures; or some combination thereof.

Disclosed herein includes a system, a method, and a device for prioritizing packet retransmission. A transmitting device can insert, for each packet of a plurality of packets of a video frame, a sequence number indicative of an order of the corresponding packet among the plurality of packets, into a header of the corresponding packet according to an application layer protocol. The transmitting device can transmit to the receiving device, at a first level of priority, the plurality of packets including the corresponding inserted sequence numbers. The transmitting device can receive an identification of one or more packets to be retransmitted to the receiving device, the identification based on at least the inserted sequence numbers of the one or more packets. The transmitting device can retransmit the one or more packets at a second level of priority that is higher than the first level of priority.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may multiplex a scheduling request (SR) associated with a first priority and a first physical uplink control channel (PUCCH) format with a hybrid automatic repeat request acknowledgement (HARQ-ACK) associated with a second priority and a second PUCCH format to form a multiplexed SR and HARQ-ACK. The UE may transmit, to a base station, the multiplexed SR and HARQ-ACK using a sequence in a PUCCH format 1 resource, wherein the sequence is based at least in part on whether the SR is a positive value or a negative value. Numerous other aspects are described.
