Abstract: A first access point (AP) receives first data for a first station (STA) and, based on the first data being of a first category, transmits the first data to a second AP for transmission by the second in a first physical layer protocol data unit (PPDU) to the first STA. The first AP receives, during or before transmission of the first PPDU, second data for a second STA, and transmits, to the second STA, a second PPDU, overlapping the first PPDU, comprising the second data.

Abstract: A wireless device, such as a station, may communicate with an access point or another station. A data transmission may overlap with an acknowledgment message associated with the data transmission. The acknowledgment message may indicate a detected error in an initial portion of the data transmission and one or more suggested links for retransmission of the data. The data may be retransmitted using a suggested link indicated in the acknowledgment message. The data may be retransmitted in full, or partially, based on the detected error and/or based on a characteristic of the detected error.

Abstract: A first station receives from a second station a first frame indicating a transmission completion time of a second frame destined to a third station. The first station transmits a request-to-send (RTS) frame to the third station and receives a clear-to-send (CTS) frame from the third STA. After receiving the CTS frame, the first STA transmits the second frame to third STA, based on determining that an estimated transmission completion of the second frame is no later than the transmission completion of the second frame indicated in the first frame.

Abstract: A station may communicate with an access point or another station. A data transmission may overlap with an acknowledgement message associated with the data transmission. The acknowledgement message may indicate a detected error in an initial portion of the data transmission. The data transmission may be stopped, or continued, based on the detected error and/or based on a characteristic of the detected error.

Abstract: A computing device may communicate with an access point. Data may be communicated using a format such as a physical layer protocol data unit. Different data formats may be used on different frequency bands. A data format may be modified to include one or more additional fields for use with a plurality of frequency bands.

Abstract: An access point (AP) transmits a trigger frame soliciting one or more trigger-based (TB) physical protocol data unit (PPDU) from a station (STA), the trigger frame comprising: a first indication associated with a first uplink resource allocation for the STA; a second indication associated with a second uplink resource for the STA; and a third indication indicating whether an aggregated acknowledgement mode is enabled. Based on the aggregated acknowledgement mode being enabled and on condition of receiving, from the STA, in response to the trigger frame, a first TB PPDU via the first uplink resource allocation and a second TB PPDU via the second uplink resource allocation, the AP transmits a BlockAck (BA) frame to the STA.

Abstract: Systems and methods for adaptive multiple input multiple output (MIMO) optical orthogonal frequency division multiplexing (O-OFDM) visible light communication (VLC) involving adaptively choosing modulation type, modulation order, MIMO configuration, and MIMO type. A receiver estimates channel information, and based on the channel information, an adaptive controller makes a selection of transmission mode and provides feedback to a transmitter, which uses a set of transmission parameters indicated in the transmission mode feedback. MIMO O-OFDM VLC provides diversity gain (i.e., higher link reliability or better coverage range) and/or multiplexing gain (i.e., higher data rate).

Abstract: One wireless communication network 3 determines an interference degree with the corresponding other wireless communication network 3 for each channel by accessing a CMDB 2 storing positional information, channel information, and respective coexistence methods of other wireless communication networks 3, selects other wireless communication network 3 to coexist, a coexisting channel, and a coexisting method thereof based on the interference degree for each determined channel, and reflects the selected network, channel, and coexistence method to the CMDB 2, and transmits a signal for requesting coexistence with respect to selected wireless communication network, to the CMDB 2, and the selected wireless communication network 3 performs a control for coexistence in the communication space between one wireless communication network and the selected wireless communication network based on the channel reflected to the CMDB 2 and the coexisting method thereof.
