  • Publication number: 20210234642
    Abstract: A method for high efficiency (HE) acknowledgement transmission may be performed by a station (STA) in a wireless local area network (WLAN) system. The method may include receiving a downlink (DL) frame indicating a resource allocation for the STA to transmit an uplink (UL) transmission. It may further include transmitting an acknowledgement frame in a single-user (SU) transmission or multi-user (MU) transmission, where the acknowledgement frame includes an indication of an operation mode change.

  • Patent number: 10979183
    Abstract: A wireless transmit/receive unit (WTRU) communicating in a wireless local area network (WLAN) system may use efficient acknowledgement (ACK) setup and transmission procedures in conjunction with other transmission and power saving techniques, such as target wake time/restricted access window (TWT/RAW), power save multi-poll (PSMP) and/or transmission opportunity (TXOP) mechanisms. In an example, a WTRU may transmit a frame including an indication that a TWT/RAW (or TXOP) period is scheduled, an indication that multi-WTRU acknowledgement (ACK)/block ACK (BA) will be used for acknowledgement, and/or targeted transmission time(s) for the transmission of multi-WTRU ACK/BA frame(s). The WTRU may trigger the start of the TWT/RAW period, and may receive at least one data frame from another WTRU(s). The WTRU may transmit multi-WTRU ACK/BA frame(s) during the targeted transmission time(s) to acknowledge the at least one data frame received from the other WTRU(s).

  • Publication number: 20210014798
    Abstract: A method for reporting power headroom is disclosed. Power headroom may be reported across all carriers (wideband), for a specific carrier, or for a carrier group. The formula used to calculate the power headroom depends on whether the carrier (or a carrier in the carrier group) has a valid uplink grant. If the carrier or carrier group does not have a valid uplink grant, the power headroom may be calculated based on a reference grant. The power headroom is calculated by a wireless transmit/receive unit and is reported to an eNodeB.

  • Publication number: 20200404589
    Abstract: Methods and apparatuses are described herein for network discovery. A wireless transmit/receive unit (WTRU) may transmit, to a first access point (AP), via a Primary Connectivity Radio (PCR), a request indicating that on a condition that the WTRU is disassociated from the first AP, the WTRU will enter a wake-up radio (WUR) only discovery mode. The WTRU may receive, from the first AP, via the PCR, a management frame that has WUR discovery elements including an indication of at least one channel used by a second AP. The WTRU may perform disassociation from the first AP. The WTRU may activate a WUR and deactivate the PCR. On a condition that the WTRU is disassociated from the first AP, the WTRU may receive, from the second AP, via the WUR, a WUR frame over the at least one channel to enable the WTRU to activate the PCR to initiate association.

  • Publication number: 20200344695
    Abstract: 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.

  • Publication number: 20200100148
    Abstract: A method and apparatus are provided for updating a sequence hopping (SH) pattern of an uplink channel during handover from a current cell having a current SH pattern. At least one downlink channel of each neighbor cell of the current cell is monitored. Information indicative of the monitored downlink channels of the neighbor cells is transmitted to the current cell. Prior to receiving a handover command from the current cell a target cell from among the neighbor cells is anticipated and a common downlink channel of the anticipated target cell is monitored to determine information representative of a target SH pattern of the target cell.

  • Publication number: 20200068590
    Abstract: Methods and apparatus may perform dual-band or multi-band mesh operations. A dual-band mesh station (MSTA) capable of operating in an O-band and a D-band may seek to join a mesh network, and may receive O-band beacons from at least one MSTA in the mesh network, where the O-band beacons may include D-band mesh information. The joining MSTA may transmit D-band beacons in a time-period specified by the O-band beacon, and on a condition that a beacon response message is received, may further transmit D-band association information via O-band management frames to join mesh network on the D-band. The joining MSTA may perform contention-free scheduled access in the D-band while sharing D-band transmission information in the O-band to enable concurrent communication in the D-band by neighboring multi-band MSTAs.

  • Publication number: 20190364453
    Abstract: Techniques may be used for interference measurement and management in directional mesh networks, including centralized and/or distributed approaches. A centralized node, such as an operations and maintenance (OAM) center, may use feedback from nodes in the mesh network to partition the nodes in the mesh network into clusters based on interference levels. Interference measurement reports may be used by the centralized node to update cluster membership. An initiating node in the mesh network may use topographical information to generate an initial interference cluster, and interference measurement frame (IMF) scheduling information may be used to schedule transmissions within the interference clusters. Techniques for opportunistic measurement campaigns, simultaneous measurement campaigns, link failure detection, and link re- acquisition in directional mesh networks may also be used.
