Abstract: A sensing receiver may be configured for wireless local area network (WLAN) sensing, The sensing receiver may be configured to receive, from a sensing transmitter, a packet, perform measurements on the received packet, and prepare a sensing measurement report, which may comprise at least a measurement report control field and a measurement report field. A measurement type dependent parameters subfield of the measurement report control field may be based on a measurement type. The sensing receiver may be configured to send, to the sensing transmitter, the sensing measurement report. Contents of the measurement report field may be based on the measurement type. The measurement type may comprise at least one of: a channel state information (CSI) type, a channel impulse response (CIR) type, or a directional multi-gigabit (DMG)/enhanced DMG (EDM) type. The packet may be a null data packet (NDP) or a physical layer protocol data unit (PPDU).

Abstract: A method of interference mitigation performed by a base station, the method comprising: receiving radar operation information; determining interference based on the radar operation information; and based on the interference determination, dynamically reconfiguring a paging configuration operated by the base station to minimize or eliminate an impact of the interference.

Abstract: Methods and devices to extend the Channel Occupancy Time (COT) for LBT-free PRACH transmission across consecutive ROs based on blind detection are disclosed. Methods and devices to extend the COT for LBT-free PRACH transmission in case of one or more unused ROs across the consecutive ROs based on dynamic indication from gNB are disclosed. Methods and devices to determine the mode of operation based on the cover-codes are disclosed. Method and devices to support the PRACH transmission from a WTRU in multiple consecutive ROs are disclosed.

Abstract: A wireless transmit/receive unit (WTRU) may combine an alignment component with an FDM based symbol to produce a signal such that it is aligned to a duration of a CP of the FDM based symbol at a receiver upon reception. A component may be added to one or more subcarriers of the alignment signal to reduce peak-to-average ratio (PAPR) of the signal.

Abstract: User-specific virtual networks may be created within one or more physical wireless networks. For example, user-specific virtual networks may follow one or more wireless transmit/receive units (WTRUs) within a network, such as a WiFi network. A network controller may create and manage a plurality of Service Set Identifications (SSIDs), create virtual access points (APs), and assign virtual AP identifiers for a plurality of WTRUs. The network controller may request physical APs to create the virtual APs with the assigned virtual AP identifiers. Switches and routers may be configured so that each of the plurality of WTRUs has a user-specific virtual router and routing path to the user-specific virtual router. The network controller may reconfigure the switches and routers to maintain the user-specific virtual router and routing path as changes occur in the network.

Abstract: A method for use in a wireless communication system for two-stage reordering of received protocol data units (PDUs). The method comprising receiving PDUs from Node-Bs, wherein each of the received PDUs has a transmission sequence number (TSN), reordering the received PDUs from Node-Bs using the TSN in a MAC layer in different reordering queues, delivering the received PDUs from reordering queues to one logical channel in the RLC layer, reordering the received PDUs in the RLC layer based on a sequence number (SN), starting a timer when at least a RLC PDU is missing based on SN of the RLC PDU, and transmitting a status report indicating a missing RLC PDU based on SN of the RLC PDU if the timer expires, wherein transmission of the status report is delayed if a RLC PDU is missing based on SN of the RLC PDU and the timer is running.

Abstract: A method and apparatus for neighbor discovery in a wireless communication system are disclosed. A neighbor seeking wireless transmit/receive unit (WTRU) may send a first beacon based on configuration information provided by the network. The neighbor WTRUs receive the first beacon and may send either a report to the network or send a second beacon to the neighbor seeking WTRU. The network may then provide neighbor WTRU information to the neighbor seeking WTRU. The neighbor discovery may be performed within a pre-defined group of WTRUs that is formed based on proximity to the WTRU and/or an attribute of the WTRU. The neighbor discovery procedure may be performed to find neighbor WTRUs in case where a WTRU fails to find any network. A neighbor list may be generated by the neighbor seeking WTRU by measuring reference signals transmitted by neighbor WTRUs on an uplink to the network.

Abstract: A method and an apparatus for providing control information for multi-carrier uplink transmission are disclosed. A wireless transmit/receive unit (WTRU) may set a happy bit for enhanced dedicated channel (E-DCH) transmissions on each uplink carrier considering aggregated transmission capability over all uplink carriers. The happy bit is set to “unhappy” if the WTRU is transmitting as much scheduled data as allowed by a current serving grant, the WTRU has enough power available to transmit at a higher rate, and total E-DCH buffer status (TEBS) requires more than a pre-configured period to be transmitted with a current effective data rate aggregated over all uplink carriers. The WTRU may send scheduling information including power headroom measured on the anchor uplink carrier and/or power headroom measured on the supplementary uplink carrier. For power headroom measurements, the WTRU may initiate a short-lived dedicated physical control channel loop on the supplementary carrier.
