Abstract: A method performed by a STA of a WLAN may comprise receiving a trigger frame, from an AP. The trigger frame may be a trigger for uplink MU data transmission and the trigger frame may indicate a traffic priority. In response to receiving the trigger frame, the STA may transmit at least one A-MPDU comprising a plurality of data units. At least one of the plurality of data units may have a priority greater than the indicated traffic priority and another one of the plurality of data units may have a priority equal to the indicated traffic priority.

Abstract: A method, apparatus, and system for multiple wireless transmit/receive units (WTRUs) communicating with a base station are disclosed. A base station, such as an eNB, may assign each WTRU of a plurality of WTRUs a portion of a transmission time interval (TTI) and then send that assignment to each respective WTRU in a control channel. The base station may then send data to one or more WTRUs in their respective assigned portions on a physical downlink shared channel (PDSCH). The portion may be one or a plurality of a time slots. The portion may be a fraction of the TTI.

Abstract: A method and apparatus for performing sidelink communications in a wireless transmit receive unit (WTRU) using Long Term Evolution (LTE) and New Radio (NR) technologies is described herein. A WTRU receives a downlink control information (DCI) on a physical downlink control channel (PDCCH) transmission from a base station, where the DCI is associated with a cyclic redundancy check (CRC) that is scrambled using a radio network temporary identifier (RNTI). The WTRU determines that the DCI indicates resources for a LTE sidelink transmission when the CRC is scrambled using a sidelink semi-persistent scheduling V-RNTI, and determines the DCI indicates resources for a new radio (NR) sidelink transmission when the CRC is scrambled using a sidelink (SL)-RNTI. The WTRU transmits SL data using the resources indicated by the determined DCI. Additional embodiments are disclosed.

Abstract: Method and apparatus for multi-carrier/multi-cell discontinuous reception (DRX)/discontinuous transmission (DTX) operations and activation/deactivation of DRX/DTX are disclosed. A wireless transmit/receive unit (WTRU) may configure at least one state variable for controlling DRX, DTX or both on a group of cells. The WTRU may receive an order for DRX or DTX activation or deactivation. The WTRU may determine a setting for the state variable based on the order. The WTRU may activate or deactivate DRX or DTX based on the setting for the state variable. The group of cells may include all cells within the same frequency band, all cells in a particular frequency or group of frequencies, and all secondary cells associated with a primary cell. The primary cell may be an uplink (UL) or downlink (DL) primary cell. The secondary cells may be UL or DL secondary cells. The WTRU may apply common, group-specific or cell-specific DRX monitoring.

Abstract: Systems, methods, and instrumentalities are disclosed for range extension, basic service set (BSS) color labeling, and multi-user (MU) fragmentation and control in WLANs. A range extension notification/enablement scheme, a clear channel assessment (CCA), a headroom indication, and/or power scaling may be provided for a range extension mode. BSS color may be provided for multiple-BSSs under an access point (AP). Uplink (UL) transmission may be provided with different fragmentation capabilities. A high-efficiency (HE) trigger-based UL NDP physical layer convergence protocol (PLCP) protocol data unit (PPDU) frame may be provided. A station (STA) may receive a trigger frame comprising a null data packet (NDP) indication and a trigger type. The STA may determine that the STA is an intended recipient of the trigger frame. The STA may prepare an NDP PPDU for a control frame and/or a management frame based on the trigger type.

Abstract: Methods and systems for negotiating an ACK policy between a STA and an AP operating in a LAN are provided. Transmission of a modified ULR frame from a STA to an AP is provided. The ULR frame may include information related to a traffic stream for which the STA is requesting one or more transmission opportunities. The related information may include a determined priority associated with the traffic stream and a requested ACK type. The transmission opportunity may be one or more of a single user transmission opportunity, part of a multi-user transmission opportunity, or a peer-to-peer transmission opportunity.
