摘要： A wireless transmitting device is configured to: obtain a compressed-mode PPDU that includes one or more SC fields, where each SC field corresponds to one MU-MIMO group of the one or more MU-MIMO groups and is indicative of a spatial stream configuration for user devices of that MU-MIMO group; and transmit the PPDU to the user devices of the one or more MU-MIMO groups over a predetermined BW. Further, a user device is configured to: receive a compressed-mode PPDU from a wireless transmitting device; and decode the PPDU to obtain a SC field corresponding to the MU-MIMO group that the user device belongs to.

摘要： An access point, AP, is provided, configured to perform coordinated beamforming with at least one further AP. The AP is configured to communicate via one or more first spatial streams of a plurality of spatial streams with one or more first non-AP stations and the further AP is configured to communicate via one or more second spatial streams of the plurality of spatial streams with one or more second non-AP stations. The AP comprises a processing circuitry configured to obtain information indicative of a total number of the plurality of spatial streams. The AP further comprises a communication interface configured to transmit a frame to each of the one or more first non-AP stations, wherein the frame comprises management information including the information indicative of the total number of the plurality of spatial streams.

摘要： The present disclosure relates to Hybrid Automatic Repeat Request (HARQ) in wireless communication technologies, particularly HARQ for IEEE 802.11, i.e. HARQ for Wi-Fi. One example transmitting device is configured to encapsulate a data unit in a container unit, and encode the container unit into a codeword set of one or more codewords. One example receiving device is configured to receive, from a transmitting device, at least one codeword set of one or more codewords, decode the codewords of the codeword set to obtain a container unit, and decapsulate the container unit to obtain a data unit. A bit-size of the container unit is equal to a bit-size of the codeword set in the transmitting device and the receiving device.

摘要： A communication transmitter retransmits a Medium Access Control (MAC) Protocol Data unit (MPDU) to a communication receiver over a communication channel using a Hybrid Automatic Repeat reQuest (HARQ) retransmission scheme. The MPDU includes a plurality of information bits. The communication transmitter includes a processor configured to determine the MPDU to be retransmitted based on a Block ACK frame received from the communication receiver, the Block ACK frame indicating previously correctly decoded MPDUs at the communication receiver, and to generate a bit sequence to be transmitted to the communication receiver, wherein the bit sequence comprises the plurality of information bits. The communication transmitter further comprises a communication interface configured to transmit the bit sequence to the communication receiver for retransmitting the MPDU to the communication receiver.

摘要： A device resolves a collision between its transmission and a simultaneous transmission of another device. The device is configured to interrupt its transmission, determine a negotiation signal, and determine at least one available resource to occupy with the negotiation signal during a negotiation period. Further, the device is configured to transmit the negotiation signal on the at least one available resource and simultaneously receive a negotiation signal on another resource from at least one other device during the negotiation period. Then, the device is configured to decide, based on all negotiation signals, whether to retransmit the interrupted transmission after the negotiation period.
