摘要： A wireless transmit/receive unit (WTRU) may receive a constellation symbol that includes indications that each are associated with a respective WTRU of a plurality of WTRUs. The WTRU may determine that a first weight associated with a first indication of the indications is different than a second weight associated with a second indication of the indications. The indications may comprise indications of bits modulated at a multi-user constellation bit division multiple access modulator (MU-CBDMAM).

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： 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 beamin the beam group.

摘要： Methods and apparatuses for multiple input-multiple output (MIMO) channel access are provided herein. A method performed by a station (STA) may include receiving, from an initiating STA, a frame including information indicating a broadcast address and a control trailer. The control trailer may include information indicating that a multi-user multiple input-multiple output (MU-MIMO) frame is to be received from the initiating STA, and information indicative of a plurality of STAs, the plurality of STAs including the STA. The method may include transmitting a response frame to the indicated broadcast address based on the received frame and receiving the MU-MIMO frame from the initiating STA.

摘要： Methods and apparatus for interference discovery for simultaneous transmission and reception are provided. In an embodiment, a station (STA) receives a STR request message from an access point (AP). The STA transmits a first STR response message to the AP based on the received STR request message. The STA receives a second STR response message transmitted from a second STA to the AP. The STA determines a received power of the received second STR response message. The STA receives a first trigger message from the AP. The first trigger message indicates a STA role field. The STA transmits interference information to the AP. The interference information is based on the determined received power. The STA role field comprises an indication of at least one or more of a primary STA and a secondary STA. The STA aggregates the interference report with a data transmission to the AP in response to the first trigger message.

摘要： Systems, methods and instrumentalities are disclosed for decoding data. For example, it may be determined, in a current slot, whether data received in a previous slot is decoded successfully. The data received in the previous slot may be included in a Physical Downlink Shared Channel (PDSCH). If the data received in the previous slot is not decoded successfully, preemptive multiplexing information may be detected in a first search space. The data received in the previous slot may be decoded, for example, using detected preemptive multiplexing information. The preemptive multiplexing information may be of a current slot. The preemptive multiplexing information may be comprised in a first DCI. A second search space of the current slot may be searched. For example, the second search space may be searched for a second DCI. The first DCI and the second DCI may be different.

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： Methods, apparatuses, systems, devices, and computer program products directed to phase-continuous frequency selective precoding are provided. Included among these classes are methods for use in connection with dynamic precoding resource block group (PRG) configuration and with codebook based transmission configuration. A representative of such methods may include any of receiving signaling indicating transmit precoding information; determining a candidate PRG size using any of the transmit precoding information, a rule for determining a PRG size and configured PRG sizes; and configuring or reconfiguring a wireless transmit/receive device in accordance with the candidate PRG size. Another of the representative methods may include reporting a transmission coherence capability of a wireless transmit/receive unit; receiving a codebook subset restriction (CBSR) commensurate with the transmission coherence capability; determining a transmit precoding matrix indices (TPMI) size based on the CBSR; receiving a TPMI; and detecting or decoding the TPMI based on the determined TPMI size.
