Abstract: A wireless transmit-receive unit (WTRU) may be provided. The WTRU may be configured to receive a first message from a first relay WTRU. The first message may indicate a service provided by a second WTRU and a first measurement associated with a broadcast message. The WTRU may be configured to determine a second measurement. The second measurement may be associated with the first message received from the first relay WTRU. The WTRU may be configured to send a second message to the first relay WTRU if the first measurement satisfies a first criteria for selecting a relay from a plurality of relays and the second measurement satisfies a second criteria for selecting the relay from the plurality of relays. The second message may comprise an indication to establish communication between the first WTRU and the second WTRU via the first relay WTRU.

Abstract: A method implemented in a wireless transmit/receive unit (WTRU) of provisioning the WTRU for communication in a temporary local network includes transmitting, to an onboarding network, information regarding a capability of the WTRU to communicate with the temporary local network. Configuration information for temporary local network provisioning is received from the onboarding network. A message identifying a provisioning configuration for use by the WTRU with the temporary local network is received from the onboarding network, using the received configuration information. A message is sent to the temporary local network using the provisioning configuration.

Abstract: Systems, methods, and instrumentalities are disclosed for range extension, basic service set (B SS) 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.

Abstract: 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.

Abstract: A method is described for using artificial intelligence (AI) components in association with first a transceiver node in a wireless network, where the first node is configured to send data over a wireless channel and to initiate a training procedure for an artificial intelligent component in a second node. The first node, having an encoder, transmits, to a decoder in the second node, a plurality of ordered training pairs, the transmission in response to a detection of a trigger condition based on a reconstruction loss value determined by the first node. The first node receives, from the second node, partially processed training information corresponding to the transmitted training pairs. The first node updates learnable parameters of the encoder based on the received partially processed training information to reduce the reconstruction loss value.

Abstract: A method performed by a base station may include transmitting a configuration message including at least information indicating a subset of a plurality of transmit beams to be used for transmitting a set of synchronization signals. The set of synchronization signals including a primary synchronization signal and a secondary synchronization signal may be transmitted. A random access channel (RACH) transmission may be received using a receive beam associated with one of the subset of the plurality of transmit beams used by the base station to transmit the set of synchronization signals. The transmitted set of synchronization signals transmitted may have a signal quality above a signal quality threshold. A reference signal may be transmitted along with a physical broadcast channel (PBCH) transmission. The reference signal may have a sequence derived from a beam index associated with the one of the subset of the plurality of transmit beams.

Abstract: 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.

Abstract: A method for receiving a backoff value at a wireless station is presented. A traffic indication map is received at the station, wherein a backoff number is implicitly assigned to the station based on a position of the station within the traffic indication map. The backoff value is determined by multiplying the backoff number by a predetermined time value.

Abstract: Methods and apparatuses are described herein for remote UE mobility management. Methods are proposed to consider the impact of coverage through PC5 interface when a remote UE is doing the cell (re)selection. A remote UE may select a serving cell considering the impact of coverage through PC5 interface when the remote UE and the Relay UE are in coverage of different cells. The remote UE may detect and reselect a cell via the Uu interface while it has selected a serving cell via a Relay UE. The remote UE may detect and reselect to a cell via a Relay UE while it has selected a serving cell via the Uu interface.
