One innovative aspect of the subject matter described in this disclosure may be implemented in a method for wireless communication. The method may be performed, for example, by a first multi-link device (MLD), that includes a first station (STA) and a second STA, to generate and provide block acknowledgment (BA) status reports for Medium Access Control (MAC) Protocol Data Units (MPDUs) transmitted by the first STA of the first MLD and the second STA of the first MLD. Another innovative aspect of the subject matter described in this disclosure may be implemented in a method for wireless communication. The method may be performed, for example, by a logical entity of a first MLD to receive and process a BA status report.

According to the present disclosure, CSI and/or a plurality of ACKs related to a group of DL data transmissions may be buffered at the UE as a GACK until a DCI trigger is received from the eNB. Once the trigger is received, the UE may transmit the CSI and/or GACK to the eNB. In this way HARQ feedback and/or CSI may be reliably communicated while reducing payload. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus send, to a UE, data transmissions associated with a first plurality of downlink subframes. In an aspect, the apparatus increments a counter for each data transmission sent to the UE. In a further aspect, the apparatus transmits, to the UE, a first trigger for a first GACK when a counter is greater than or equal to a threshold.

A node in a wireless mesh network determines that a threshold level of duplicate network protocol data units (PDUs) are received. Further, the node receives one or more network PDUs comprising respective segments of transport data in a transport PDU. The node relays a subset of the received one or more network PDUs comprising respective segments to one or more neighboring nodes. The subset is relayed based on determination that the node has received a threshold level of duplicate network PDUs.

The present disclosure provides a method for retransmitting at least one lost network packet based on a transport stream (TS) format and an user datagram protocol (UDP), including: receiving a plurality of media packets having the TS format by a terminal from a media server via the UDP, determining whether continuity counter (CC) fields of the media packets is continuous, transmitting a transmission request packet to a media retransmission server by the terminal via the UDP, wherein the media retransmission server is configured to analyze the retransmission request packet to obtain a least one lost media packet having the TS format, packaging the at least one lost media packet into a retransmission acknowledge packet by the media retransmission server, and transmitting the retransmission acknowledge packet from the media retransmission server to the terminal via the UDP.

The disclosure relates to methods, devices, and systems for wireless communications. In some wireless communications systems, a base station may transmit a multicast message to a group of user equipment (UEs), and the UEs may provide feedback for the multicast message. In some implementations, the base station may configure the UEs to transmit feedback for multicast messages. In some example, the UEs may transmit group-negative acknowledgment (NACK) feedback information for multicast messages that are not successfully received at the UEs. In some other examples, each UE may be configured with UE-specific uplink control channel resources for transmitting hybrid automatic repeat request (HARQ) feedback for a multicast message. In some implementations, a UE may support feedback for both unicast and multicast messages. The semi-static codebook for unicast, multicast, or both may account for whether the UE is capable of concurrently receiving unicast and multicast messages in a slot.

This application provides a method and a corresponding apparatus. One example method includes: A transmitting side receives an RLC status report from a receiving side, where the RLC status report includes at least one piece of status information, each of the at least one piece of status information indicates one or more receiving statuses of one or more consecutive RLC service data units (SDUs) that are not successfully received, and the at least one piece of status information is sequentially sorted in ascending order of RLC SDU sequence numbers (SNs) in the RLC status report; and if the last piece of status information in the RLC status report indicates that a part of data of a first RLC SDU is lost, the transmitting side determines, based on the RLC status report, whether a receiving status of the first RLC SDU is completely reflected in the RLC status report.

A method includes transmitting data by a first interface card in a trusted domain. A second interface card in an untrusted domain receives the data. The second interface card stores the data in a first memory location of a plurality of first memory locations in the untrusted domain and verifies integrity of the data. The second interface card writes a result of the verifying in a second memory location of a plurality of second memory locations in the untrusted domain. The first interface card retrieves the result of the verifying from the second memory location of the plurality of second memory locations in the untrusted domain. The first interface card creates a table configured to identify and track a state of the second memory location of the plurality of second memory locations in the untrusted domain corresponding to the data received from the first interface card in the trusted domain.

In a wireless local area network system, a shared AP may receive an announcement frame and a data frame from a sharing AP for multi-AP transmission. In the present disclosure, the announcement frame may be transmitted in a broadcasting scheme. The data field of the announcement frame may include an identifier (ID) of the shared AP. The shared AP may receive a data frame from the sharing AP. In the present disclosure, a receiver address (RA) field of the data frame may include an address of the sharing AP. The shared AP may decode the data frame based on the address of the sharing AP included in the RA field of the data frame.

A method for use in a cellular communications system in which system traffic can be exchanged between transceivers comprises receiving traffic from a second transceiver at a first transceiver. The traffic includes data units that are each associated with an identifier. The data units are also divided into segments. The method additionally includes sending status information from the first transceiver to the second transceiver. The status information pertains to one or more data units transmitted by the second transceiver. Additionally, sending the status information includes, for non-received and partially received data units, sending information indicating the data units were non-received or partially received and, for partially received data units, sending information indicating which parts of the data units were not received.

A method for determining a receiving status of a data frame and a first multi-link device. The method includes sending data frames to a second multi-link device over multiple links; receiving, over a first link in the multiple links, a block acknowledgment (BA) frame, where a bitmap in the BA frame indicates a receiving status of a data frame transmitted over the first link and indicates a receiving status of a data frame transmitted over a second link in the multiple links, and determining, based on a first time and a second time, a receiving status of a data frame corresponding to a first bit.
