Abstract: An encryption mechanism used on cooperative multi-band wireless STA architecture that enables full duplex operations. In encrypting a frame, an AAD can be constructed by using a selected MAC address, which may not be associated with a band to be used for transmitting the frame in an upcoming TXOP. An STA that supports simultaneous transmission in a multi-band operation uses the same MAC address to encrypt the frames to be transmitted on different bands. An AAD is constructed by using a same MAC address corresponding to one of the transceivers. A transmit STA may specify band information used for encryption in the MAC header, which serves to signal the receive STA to decrypt the frame by using the proper information.

Abstract: Techniques pertaining to multi-link operation (MLO) assisted 60 GHz beamforming training and data transmission in wireless communications are described. An apparatus (e.g., as a 60 GHz-capable MLO station (STA)) performs MLO assisted 60 GHz operations by: (i) performing discovery and association; and (ii) performing either or both of beamforming training and data transmission in a 60 GHz band.

Abstract: Techniques pertaining to transmission protection with static puncturing in wireless communications are described. An apparatus (e.g., a station (STA)) receives a control frame with bandwidth signaling that is transmitted in a channel width of the control frame including one or more non-punctured non-primary subchannels within the channel width. The apparatus then determines the one or more non-punctured non-primary subchannels within the channel width of the control frame and also determines whether to transmit a response control frame responsive to receiving the control frame. Depending on a result of the determining, the apparatus either refrains from transmission of the response control frame or transmits the response control frame in at least one subchannel within the channel width of the control frame.

Abstract: A first multi-link device (MLD) enables an enhanced multi-link single-radio (EMLSR) mode or an enhanced multi-link multi-radio (EMLMR) mode. A first station (STA) affiliated with the first MLD receives from a second MLD and in a first operating channel of the first STA an initial control frame indicating an allocated resource unit (RU), which is indicated in a Secondary RU Allocation subfield in the initial control frame. A second STA affiliated with the first MLD switches from a second operating channel of the second STA to an allocated channel in which the allocated RU is located. The second STA then receives information from the second MLD on the allocated RU during a transmission opportunity (TXOP).

Abstract: Embodiments of the present invention provide a method and apparatus for hybrid ARQ acknowledgement and retransmission requests for decoding failed MPDUs of an A-MPDU received by an STA. The source address and receiver address of a failed MPDU can be verified according to a MAC header CRC that can be included in an A-Control frame, for example. For verifying the source address and the receiver address in MAC header, according to some embodiments, the MAC header CRC is jointly calculated over the first two octets of the MPDU delimiter of an A-MPDU subframe. Moreover, a Hybrid ARQ frame is defined to include Block Ack Bitmap subfield representing the received status of a plurality of MPDUs according to starting sequence control number, for example.
