Abstract: A method for performing enhanced preamble puncturing in a wireless communication system and associated apparatus are provided. The wireless communication system may include a first wireless transceiver device having an enhanced preamble puncturing capability, where the first wireless transceiver device is configured to operate in a first transmission bandwidth including one primary and multiple non-primary channels. The method may include: determining at least one interfered channel in at least one of the primary and non-primary channels; and performing the enhanced preamble puncturing on transmission of physical layer (PHY) protocol data units (PPDUs) including transmitting, in the aforementioned at least one interfered channel, at least one first PHY protocol data unit (PPDU) configured to have a lower power than a power of other PPDUs transmitted in other primary or non-primary channels.

Abstract: Techniques pertaining to coverage enhancement for 6 GHz wireless communications are described. A first station (STA) communicates with a second STA in a 6 GHz wireless band and/or low-power indoor (LPI) channels. The first STA performs a receiving signal combination and detection across multiple bandwidths such that a power level or a signal strength is enhanced in communicating with the second STA.

Abstract: Techniques pertaining to low-power enhanced multi-link single radio (EMLSR) listen in wireless communications are described. A first multi-link device (MLD) reduces power consumption while supporting a latency-sensitive application by performing certain operations. The first MLD first listens at a lower power in a narrower bandwidth to receive an initial physical-layer protocol data unit (PPDU) from a second MLD as part of a frame exchange. In response to receiving the initial PPDU, the first MLD switches from the narrower bandwidth to a wider bandwidth to complete the frame exchange with the second MLD in the wider bandwidth. In reducing the power consumption, the first MLD reduces its power consumption to the lower power when operating in the narrower bandwidth compared to a higher power used by the first MLD when operating in the wider bandwidth.

Abstract: A multi-user downlink orthogonal frequency-division multiple access (OFDMA) configuration method includes: assigning contiguous resource units (RUs) included in a channel to a plurality of stations, respectively; and assigning, by an access point (AP), one modulation and coding scheme (MCS) to each of the plurality of stations. Data rates of modulation and coding schemes that are assigned to first stations and associated with contiguous first RUs assigned to the first stations are monotonic, where the first stations are included in the plurality of stations.

Abstract: A multi-link device (MLD) includes a transmit (TX) circuit, a receive (RX) circuit, and a control circuit. The control circuit controls the RX circuit to receive a first frame under an operation mode parameter with a first setting, control the TX circuit to transmit a second frame responsive to the first frame under the operation mode parameter with the first setting, and after the second frame is transmitted, controls the RX circuit to receive at least one physical layer protocol data unit (PPDU) under the operation mode parameter with a second setting, wherein the second setting is different from the first setting.

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.
