    Abstract: Systems, methods, and devices for beamforming (BF) training are disclosed. In some examples, a receiver is configured to receive sector sweep (SSW) training frames from an initiator device that each indicate an antenna sector of the initiator device. A transmitter is configured to transmit sector sweep (SSW) training frames to the initiator device that indicate a best received antenna sector of the initiator device. The receiver receives a sector sweep feedback (SSW FB) frame from the initiator device, and the transmitter transmits transmit a sector sweep acknowledgement (SSW ACK) frame to the initiator device that indicates an antenna sector of the initiator device that is different from the antenna sector indicated by the SSW FB frame, if the SSW FB frame was best received by an antenna not corresponding to the best received antenna sector of the initiator device.

  • Patent number: 11272466
    Abstract: Maintaining time alignment with multiple carriers is contemplated. A group of uplink carriers (UL CC sets) that operate with a single Timing Advance (TA) may be determined, and a TA value may be applied to a specific UL CC set. A wireless transmit/receive unit's (WTRU) capability of using multiple TAs may define a group index of a few bits for each UL CC set. A TA Command received in a Random Access Response message may be used to apply the TA value to each UL carrier of the UL CC set. The WTRU may determine which UL CC set the TA value applies to based on which DL carrier the command was transmitted from. The WTRU may determine which UL CC set the TA value applies to based on the Group Index being explicitly provided in the command. The WTRU may release multi-CC configurations upon Time Alignment Timer (TAT) expiry.

  • Publication number: 20220046719
    Abstract: Systems, methods, and instrumentalities are disclosed for concurrent link setup and downlink data retrieval, e.g., for high efficiency WLAN. An access point (AP) may send a trigger element that allocates a resource for pre-association transmissions with the AP. The trigger element may allocate the resource for random access and/or deterministic access. The AP may receive, from an unassociated STA, a first frame via one or more resource units (RUs) allocated in the trigger element. The AP may determine a pre-association identifier (PID) that identifies the unassociated STA. The AP may send the PID to the unassociated STA, for example, in the trigger element or in the multi-STA ACK. The AP may send a second frame associated with a multi-user (MU) transmission that includes the PID. The AP may send a trigger frame that includes the PID.

  • Publication number: 20220038771
    Abstract: Power aware adaptation for a power aware video streaming system may be based on the complexity information conveyed in different ways. A complexity level of a data stream, such as a video data stream, may be selected as a function of a remaining battery power of a wireless transmit/receive unit (WTRU) and on a state set of a plurality of state sets that may be stored and/or managed by the WTRU. These state sets may correspond to, for example, different content sources and/or different complexity estimation algorithms and may be used to select the complexity level of the data stream. The data stream may then be received at the selected complexity level. The complexity level and/or a bitrate of the data stream may be adapted to accommodate, for example, the remaining battery power and/or other circumstances. The adaptation may be customized according to the objectives of use cases.
