Abstract: Duplicated packet transmission methods are provided. The duplicated packet transmission method may include the following steps. A sender may determine whether to pad at least one duplicated packet into a multi-user physical-protocol-data-unit (MU-PPDU) based on at least one condition. Then, the sender may transmit the MU-PPDU with the duplicated packet to at least one receiver when the condition is met.

Abstract: A link selection system, for allocating a plurality of available links to a plurality of multi-link-device (MLD) stations, is provided. The link selection system includes the following elements. (1) A monitoring unit, for monitoring a traffic type of each of the MLD stations and a channel status of each of the available links. (2) A detecting unit, for detecting whether the traffic type is a QoS traffic or a heavy traffic and whether the channel status is a congested condition. (3) An arbitrating unit, for arbitrating a link configuration of the available links for the MLD stations based on the traffic type and the channel status. The available links are associated with a multi-link-operation (MLO) device.

Abstract: The invention provides a method and related network circuit for improving latency of a wireless network (e.g., a Wi-Fi network). The method may be executed by a device (e.g., a Wi-Fi station) of the wireless network, and may comprise: configuring a duration threshold according to a latency requirement, and, when transmitting a physical layer protocol data unit (PPDU) over the wireless network, causing the PPDU not to be longer than the duration threshold. In an embodiment, the latency requirement may be obtained by handshaking with one or more other devices of the wireless network.

Abstract: A communication device for setting a packet-transmission rate for transmitting aggregated-media access-control protocol data unit (A-MPDU) packets is provided. The communication device includes a first processor, a second processor, and a transceiver unit. The first processor transmits an initial rate at each specific period and transmits a hardware indicator. The second processor receives the hardware indicator and transmits a real-time rate, wherein the second processor adjusts the real-time rate according to the hardware indicator. The transceiver unit is coupled to the first processor and the second processor. The transceiver unit receives the initial rate and the real-time rate, wherein the transceiver unit sets the packet-transmission rate according to the initial rate and the real-time rate.

Abstract: A device is provided. The device includes: at least one antenna, a plurality of buffer sets, and a circuit. Each buffer set includes a plurality of queue buffers, and each queue buffer is dedicated for a respective application category. The circuit communicates with one or more stations through the at least one antenna. In response to the circuit determining that a plurality of incoming frames or packets are classified into the same application category, the circuit performs an intra-Access Category (intra-AC) scheduling mechanism to determine priorities of data stored in the queue buffers in the same application category according to QoS (quality-of-service) requirements of each station so as to arrange for an MU (multi-user) PPDU (physical-layer protocol data unit) to be transmitted to at least a portion of the stations.

Abstract: A method for acquiring and reporting resource needs of shared Access Points (APs) for multi-AP coordination is provided. A sharing AP transmits a control frame for Multi-AP coordination to a shared AP. The sharing AP receives a report on resource needs from the shared AP in response to the transmission of the control frame. The sharing AP allocates time-frequency resources of a Transmit Opportunity (TXOP) to the shared AP based on the report on resource needs.
