Abstract: A channel scan method includes: configuring a receiving circuit to perform a single signal reception of a first bandwidth to generate a signal reception result; and performing channel scan upon the signal reception result to detect a channel status of each channel having a second bandwidth smaller than the first bandwidth. In addition, a channel scan device has a receiving circuit, a control circuit, and a scan circuit. The control circuit controls the receiving circuit to perform a single signal reception of a first bandwidth to generate a signal reception result. The scan circuit performs channel scan upon the signal reception result to detect a channel status of each channel having a second bandwidth smaller than the first bandwidth.

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.

Abstract: A packet receiving method is provided. The packet receiving method includes the following steps: during receipt of the first packet by a receiver, detecting if any packet arrives at the receiver after a first packet; and when it is detected that a second packet arrives at the receiver during the receipt of the first packet, determining whether to decode the first packet or the second packet.

Abstract: Techniques pertaining to trigger-based (TB) implicit feedback for implicit beamforming in wireless communications are described. An apparatus (e.g., an access point (AP)) triggers each of one or more stations (STAs) to transmit a respective feedback. The apparatus estimates a respective steering matrix with respect to each of the one or more STAs based on the respective feedback. The apparatus then transmits a respective steered data to each of the one or more STAs based on the respective steering matrix.

Abstract: A communicating device includes: a first packet detector and a second packet detector, wherein the first detector is arranged to detect a first preamble included in a first response packet over a first sub-channel; and the second packet detector is arranged to detect a second preamble included in a second response packet over a second sub-channel. The second sub-channel is different from the first sub-channel, and the first packet detector and the second packet detector co-exist in the communicating device.
