摘要： Methods, apparatus, systems, architectures and interfaces for compressing hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback bits performed by a wireless transmit/receive unit (WTRU) receiving a transmit block (TB) including code block group (CBG) data are provided. The method includes receiving, by the WTRU, information associated with transmitting compressed HARQ-ACK feedback information, receiving, by the WTRU, a TB; determining, by the WTRU, a countdown downlink assignment index (CD_DAI) associated with the received TB; generating, by the WTRU, the compressed HARQ-ACK feedback information by compressing HARQ-ACK feedback bits associated with the received TB; and on condition that: (1) the CD_DAI is equal to zero or (2) the WTRU determines to provide feedback information, transmitting the compressed HARQ-ACK feedback information.

摘要： Mechanisms may be used for aggregating acknowledgement (ACK), block ACK (BA) and/or short packets transmissions for multi-user (MU) wireless communication systems. Aggregation mechanisms may be used for uplink (UL) and/or downlink (DL) orthogonal frequency division multiple access (OFDMA), and/or UL/DL multiple-user multiple input multiple output (MU-MIMO) transmissions, for example. Multi-user short packets may be aggregated and/or simultaneously transmitted for DL, UL, or peer-to-peer (P2P) transmissions.

摘要： An AP/PCP may perform user selection/pairing/grouping based on a measurement of an analog transmission (e.g., signal to noise ratio (SNR) or signal to interference plus noise ratio (SINR)). The SNRs may be used, for example by the station, to determine best beams and/or beam pairs and/or worst beams and/or beam pairs. A station may feed back the best few beams and/or beam pairs for a Tx and Rx virtual antenna pair. A station may feed back the worst few beams for the Tx and Rx virtual antenna pair. The AP/PCP may receive the indication(s) and/or use the indication(s) to group the stations.

摘要： Device, systems, and/or techniques for using sub-channel signaling information between an access point and a first station are disclosed. An uplink trigger sent from the access point to the first station may be received. A map may be transmitted from the first station indicating at least one sub-channel that is available for spatial sharing by a second station. The first station may receive an acknowledgement from the access point that data was transmitted from the second station on the at least one sub-channel and/or received by the at least one access point. An OFDMA transmission having a sub-channel/sub-band available for transmitting data may be determined. An energy in the sub-channel/sub-band may be measured and/or compared to a dynamic and/or static threshold. Whether a sub-channel/sub-band is free or busy may be determined for example based on if the measured energy is, or is not, greater than the threshold.

摘要： Methods and apparatuses are described herein for rediscovery and medium access for wake-up radios. For example, a wireless transmit receive unit (WTRU) may receive, via a first transceiver, a frame that includes a wake-up radio (WUR) operation element having a first counter value. The WTRU may deactivate the first transceiver and activate a second transceiver, wherein the first transceiver enters into a doze state and the second transceiver is in an awake state. The WTRU may then receive, via the second transceiver in the awake state, a WUR frame that includes a second counter value indicating an update of a plurality of basic sewer set (BSS) parameters associated with the first transceiver. On a condition that the second counter value is different than the first counter value, the WTRU may activate the first transceiver to update the plurality of BSS parameters, wherein the first transceiver enters into an awake state.

摘要： Methods and apparatuses are described herein for multiple AP coordination in wireless local area networks (WLANs). For example, a station (STA) may receive, from a first access points (APs), a probe response frame that includes one or more indicators indicating multiple AP operation capabilities of the first AP and a second AP. The STA may transmit, to at least one of the first AP or the second AP, a multiple AP association request frame that enables the first AP to be associated with the second AP for a multiple AP operation. The STA may receive, from the first AP, a first multiple AP association response frame indicating acceptance or rejection of the multiple AP operation with the first AP. The STA may receive, from the second AP, a second multiple AP association response frame indicating acceptance or rejection of the multiple AP operation with the second AP.

摘要： Methods and an apparatus are disclosed for orthogonal frequency division multiplexing (OFDM) and/or single carrier (SC) based multiple input multiple output (MIMO) hybrid beamforming (HBF) including determining the capabilities of a station (STA) such as the capability for hybrid beamforming, single user MIMO (SU-MIMO), and multi user MIMO (MU-MIMO). An announcement frame with a control trailer may be transmitted to signal a transmission configuration. The announcement frame may be a grant frame or a request to send (RTS) frame if the STA is SU-MIMO capable or a RTS frame or a DMG clear to send (CTS)-self frame if the STA is MU-MIMO capable. One or more directional multi-gigabit (DMG) antennas may be configured based on the announcement frame. One or more sounding symbols may be transmitted and feedback may be provided based on the sounding symbols. An HBF signal may be transmitted based on the sounding symbol(s) and/or feedback.

摘要： Methods and apparatus are described herein for dynamic allocation of multiple channels and data streams for multi-channel transmission and multiple-input and multiple-output (MIMO). For example, a station (STA) may receive an enhanced poll (EPoll) frame that includes a time offset, a channel offset and antenna/sector settings from an access point (AP). The STA may transmit, based on the received EPoll frame, an enhanced service period request (ESPR) frame that includes a MIMO control field and a multi-channel control field. The MIMO control field may indicate whether the STA supports MIMO transmission. The multi-channel control field may indicate whether the STA supports multi-channel transmission. Upon transmitting the ESPR frame, the STA may receive an enhanced grant frame from the AP. The enhanced grant frame may include an antenna configuration and a multi-channel allocation to enable the STA to perform the MIMO transmission and the multi-channel transmission.
