  • Patent number: 11737141
    Abstract: One wireless communication device includes a transmitter circuit and a control circuit, wherein the control circuit sets a request to send (RTS) frame, and controls the transmitter circuit to transmit the RTS frame via at least one channel excluding a preamble punctured channel. Another wireless communication device includes a transmitter circuit and a control circuit, wherein the control circuit sets an RTS frame, and controls the transmitter circuit to transmit the RTS frame via a plurality of channels including the preamble punctured channel.

  • Publication number: 20230224963
    Abstract: Various techniques pertaining to a special dual clear-to-send (CTS) mode for improvement in collision avoidance in wireless communications are described. A first station (STA) transmits a request-to-send (RTS) and, in response, receives a first CTS from a second STA. The first STA waits to receive a second CTS from the second STA before transmitting data to the second STA responsive to the first CTS being of a first type and the second CTS being of a second type different from the first type. The first STA then transmits the data to the second STA upon passage of a waiting period.

  • Publication number: 20230188266
    Abstract: One wireless communication method includes: receiving a request action frame; and in response to the request action frame, generating and sending an acknowledgement (ACK) control frame that is configured to serve as a response action frame for the request action frame, wherein the response action frame is not solicited by the request action frame. Another wireless communication method includes: receiving a request action frame; and in response to the request action frame, generating and sending an acknowledgement (ACK) control frame and a time-constrained response action frame following the ACK control frame, wherein the time-constrained response action frame is solicited by the request action frame.

  • Publication number: 20210314951
    Abstract: A wireless communication terminal including a wireless transceiver and a controller is provided. The wireless transceiver performs wireless transmission and reception to and from an AP. The controller is coupled to the wireless transceiver, and is operable to configure the wireless communication terminal to operate as a non-AP STA, and transmit a MU PPDU with a single RU spanning a partial bandwidth of the MU PPDU to the AP via the wireless transceiver. In particular, the partial bandwidth excludes a frequency band of a primary channel.

  • Patent number: 9894466
    Abstract: A transmission method comprises: connecting a first wireless device to a second wireless device; determining by the first wireless device whether a silence time is assigned to the second wireless device; setting a communication period with the second wireless device according to the assigned silence time if the silence time assigned to the second wireless device is recorded in the first wireless device; and determining by the first wireless device the silence time according to a traffic transmitted from the second wireless device if the silence time assigned to the second wireless device is not recorded in the first wireless device.

  • Publication number: 20140328233
    Abstract: A portable device for receiving broadcast information is provided. A mixer down-converts a radio-frequency signal with a local oscillation clock to provide an intermediate frequency signal. A filter is arranged to filter the intermediate frequency signal. An analog-to-digital converter converts the filtered intermediate frequency signal into a digital signal according to a sampling rate. The broadcast information is obtained according to the digital signal. The local oscillation clock has a first frequency in a normal mode and a second frequency in a power-saving mode, and the second frequency is lower than the first frequency.
