摘要: 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.

摘要: A method and apparatus may be configured to support coordinated orthogonal block-based resource allocation (COBRA) operations. An access point (AP) may be configured to indicate to a plurality of stations (STA)s that it may support COBRA. Each WTRU may be configured to indicate to the AP that it can support COBRA as well. The AP may be configured to transmit a COBRA controller information element (IE) comprising a plurality of fields to each of the WTRUs. Each WTRU may be configured to transmit a COBRA controllee IE comprising a plurality of fields. STA grouping management, group maintenance, channel access, beamforming, sounding and frequency and synchronization procedures are also described.

摘要: Systems, methods, and instrumentalities are disclosed for multiple resource unit (RU) allocation for OFDMA WLAN. A transmitter may parse an encoded bit stream into a plurality of spatial streams. The transmitter may determine an allocation of encoded bits of the plurality of spatial streams to a plurality of interleavers. The transmitter may allocate the encoded bits to the plurality of interleavers based on the determined allocation. The allocation of the encoded bits may be determined based on one or more of channel related feedback, an RU configuration associated with the transmission, a quality of service (QoS), and/or traffic priorities. The transmitter may interleave the encoded bits using the plurality of interleavers. The transmitter may combine the interleaved encoded bits from the plurality of interleavers into a sequenced bit stream.

摘要: A WTRU may include a memory and a processor. The processor may be configured to receive beam grouping information from a gNB or transmission and reception point (TRP). The beam grouping information may indicate a group of beams that the WTRU may report using group-based reporting. The group-based reporting may be a reduced level of reporting compared to a beam-based reporting. The group-based report may include measurement information for a representative beam. The representative beam may be one of the beams in the group or represents an average of the beams in the group. Alternatively, the representative beam may be a beam that has a maximum measurement value compared to other beams in the group. The group-based report may include a reference signal received power (RSRP) for the representative beam and a differential RSRP for each additional beam in the beam group.

摘要: Methods, apparatus, systems, architectures and interfaces for reference signal (RS) configuration, generation, and/or transmission in a transmitter/receiver. The method includes receiving information indicating any of at least first and second modes of operation for transmitting a discrete Fourier transform (DFT)-spread-orthogonal frequency division multiplexing (DFT-s-OFDM) symbol including a reference signal (RS), and transmitting the DFT-s-OFDM symbol including: (1) the RS and data tones, on condition that the information indicates the first mode; or (2) the RS and null tones, on condition that the information indicates the second mode, wherein the DFT-s-OFDM symbol is divided into a number of segments, each including a chunk of RS tones, and wherein any of a size or a location of the chunk is determined according to any of the first or second modes.
