  • Patent number: 12218714
    Abstract: A resonance magnetic coupling (RMC) communication may be enabled between devices. A device may use a discovery mechanism to transmit and exchange information. A device may use the discovery mechanism to establish a RMC communication channel and may determine its parameterization. A device using a RMC communication may transmit a discovery signal to determine channelization and/or properties of the RMC link. The discovery signal may be generated in the form of a beacon transmission. A signal sequence may be employed for a discovery signal. A device using a RMC communication may transmit a sequence of beacon or discovery signals to track characteristics of the RMC link. Beacon scheduling may be used for RMC communications, and the communication channel may not be static and may be a function of distance and orientation. A device using a RMC communication may sense the channel for potential beacon or sequence signals from other devices.

  • Publication number: 20240284456
    Abstract: Procedures, methods, architectures, apparatuses, systems, devices, and computer program products related to a Wireless Transmit-Receive Unit (WTRU) operating in a network, for supporting paging using an Ultra-Low Power (ULP) receiver, are disclosed. A WTRU may receive a ULP-specific configuration, and may activate the ULP receiver, and inactivate the Uu receiver, when support of ULP paging operation, by the network, is determined. The ULP receiver may detect a Low-Power Wake-Up Signal (LP-WUS) and may activate the Uu receiver and perform PDCCH monitoring. Under condition that the WTRU detects, in the channel monitoring, its identifier in a paging message received via the Uu receiver, the WTRU initiates a connection establishment or a connection resume procedure.

The first WTRU may receive one or more transmissions indicating whether the second WTRU is being paged for the SL service. On a condition that the second WTRU is being paged for the SL service, the first WTRU may receive one or more SL messages associated with the SL service and directed to the second WTRU. The first WTRU may transmit to the second WTRU, SL paging information indicating availability of the received one or more SL messages.

  • Publication number: 20240236941
    Abstract: Procedures, methods, architectures, apparatuses, systems, devices, and computer program products are disclosed that may be implemented in a wireless transmit/receive unit (WTRU), such as where the WTRU is in an inactive and/or idle (e.g., RRC) state. In one representative method, the WTRU may receive a downlink (DL) small data transmission (SDT) indication with respect to a paging occasion. The WTRU may receive the indicated DL SDT payload which may be multiplexed with a paging record for the paging occasion and/or with one or more configured DL SDT PDSCH resources. Hybrid automatic repeat request (HARQ) feedback information for the DL SDT payload may be transmitted using configured PUCCH resources and/or may be multiplexed with a random access channel (RACH) procedure. The DL SDT payload may be received by the WTRU without transitioning to a connected (e.g., RRC) state.

  • Publication number: 20240236739
    Abstract: Systems, methods, and instrumentalities are described herein for idle mode mobility in an ultra-low power (ULP) system. Idle mode mobility in a ULP system may support energy efficient downlink signaling. An association may be identified between a Uu cell and a ULP cell. Switching between Uu cells may limit power savings gains from ULP receivers. Enabling switching between ULP cells without switching between Uu cells may help maintain the power savings gains from ULP receivers. A wireless transmit/receive unit may be configured to perform ULP cell reselection, for example, without triggering Uu cell reselection (e.g., to maintain power savings gains).

  • Publication number: 20240188107
    Abstract: The disclosure generally pertains to methods and apparatus for on-demand low-power sidelink channel reservation acquisition in wireless communication systems. A WTRU may determine to request on-demand reports related to sidelink resource usage. A WTRU that receives the report may generate a report based on its knowledge of sidelink resource usage. The responding WTRU may determine a priority associated with the report based on the relative amount of information it has regarding the sidelink resource usage. A response window for the response may be determined based on the priority. The responding WTRU then transmits the report in the corresponding response window. If a collision is detected for the report transmission, the response window may be extended and the report may be retransmitted in the extended response window.

  • Publication number: 20240147370
    Abstract: Methods and apparatuses are described herein for chained and delayed wake-up. For example, a station (STA) may determine, at the formation of a group of STAs, a common service period for the group. The STA may determine a deferral time for a first STA of the group. The deferral time may indicate when the first STA wakes up to receive a wake-up packet. The STA may receive, from an access point (AP), during a service period in which the STA acts as a head node for communication with the AP, a wake-up packet addressed to the first STA. The STA may transmit, based on a determination that the deferral time associated with the wake-up packet addressed to the first STA ends after the service period in which the STA acts as a head node, a wake-up command that includes the wake-up packet addressed to the first STA.

  • Publication number: 20240106532
    Abstract: Systems, methods, and devices for wireless transmissions based on backscattering. A backscatter indication message (BID) is received from an access point (AP). An interrogation signal is received. Uplink data is transmitted to the AP based on the BID and the interrogation signal. In some implementations, the interrogation signal is received from the AP. In some implementations, the BID indicates a backscatter duration, and the uplink data is transmitted to the AP for the backscatter duration. In some implementations, the uplink data is transmitted to the AP concurrently with receiving the interrogation signal. In some implementations, energy is harvested from the interrogation signal. In some implementations, the uplink data is transmitted to the AP subsequent to the interrogation signal, based on the energy harvested from the interrogation signal. In some implementations, the interrogation signal includes a compensation signal based on channel conditions and/or based on backscattering from the WTRU.
