Abstract:
A method of managing carrier aggregation for a multi-radio access technology (RAT) wireless transmitter/receiver unit (WTRU) is disclosed. The method may include: receiving, by the WRTU over a primary channel associated with a RAT of a first type, provisioning information for provisioning a supplementary channel associated with a RAT of a second type; establishing the supplementary channel associated with the RAT of the second type based on the received provisioning information; and wirelessly exchanging, by the WRTU, first data associated with a communication over the primary channel via the RAT of the first type, while wireless exchanging second data associated with the communication over the supplementary channel via the RAT of the second type.
Abstract:
A method of managing one or more test measurements associated with a communication system using a wireless transmit/receive unit (WTRU) is disclosed. The method includes receiving, by the WTRU, a measurement configuration including at least a trigger indicating a condition or event for initiation of the one or more test measurements; determining, by the WTRU, whether the trigger has been satisfied, as a determination result; initiating the one or more test measurements in accordance with the determination result; and measuring, by the WTRU, the one or more test measurements.
Abstract:
The disclosure pertains to methods and apparatus for supporting positioning service continuity. One representative method includes receiving, by a wireless transmit/receive unit (WTRU), a configuration for supporting positioning service continuity during a handover. The method additionally includes supporting, by the WTRU, positioning service continuity according to the configuration at least in part by determining one or more transmissions to be performed. The method also includes assisting a radio access network with a data link handover by performing the one or more transmissions according to the configuration.
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:
Methods, apparatus and systems are disclosed. One method may include a wireless transmit/receive unit (WTRU) receiving a transmission including a data unit (DU) on a first set of resources. The WTRU may select an artificial intelligence (AI) filter based on the first set of resources and input the DU or a part of the DU to the selected AI filter. The WTRU may perform AI filtering on the inputted DU or part thereof to output any of: a set of AI-based transmission parameters or an AI-processed DU. The AI-processed DU may include: a first portion of the DU processed by the AI filter and a second portion of the DU processed by a rule-based component, or the DU processed by the AI filter. The WTRU may transmit any of: the AI-processed DU using a set of rule-based transmission parameters, or a rule-based DU using the AI-based transmission parameters.
Abstract:
A method and apparatus for configuring a Long Term Evolution (LTE)-controlled Wireless Local Area Network (WLAN) interface for a wireless transmit/receive unit (WTRU) are described. A method includes receiving LTE Radio Resource Configuration (RRC) signaling that provides parameters for the WTRU to configure the LTE-controlled WLAN interface. The LTE RRC signaling includes a set of WLAN access points (APs), an indication that the WTRU is permitted to autonomously initiate association with a WLAN within the set, a type of one or more bearers to use for the LTE-controlled WLAN interface, WLAN-related security information, and a configuration for the WTRU to report a status of an association with a WLAN AP. The WTRU selects a WLAN AP to associate to from the list and initiates association to the selected WLAN AP using at least the WLAN-related security information.
Abstract:
A method and apparatus may be used to enable reception of a downlink (DL) shared channel in a cooperative multipoint transmission (CoMP). The method and apparatus may determine whether CoMP is applied to a transmission. The method and apparatus may acquire other CoMP related information. The method and apparatus may apply to non-transparent CoMP scenarios.
Abstract:
A method performed by an anchor wireless transmit/receive unit (WTRU) having an Extended Reality (XR) application includes transmitting to a base station (BS) a request for a candidate set of collaborative WTRUs, the request including pose information to identify the candidate set of collaborative WTRUs, receiving from the BS a first set of collaborative WTRUs, determining, by the anchor WTRU, a second set of WTRUs from the first set of WTRUs that align with at least one of a Field of View (FoV) requirement, the pose information, and XR application parameters of the anchor WTRU, and transmitting, to the BS, an indication of the second set of WTRUs as selected collaborative WTRUs.
Abstract:
Light and/or Inactive state connectivity and/or autonomous mobility techniques are contemplated. A WTRU may, for example, have an inactive/idle mode, a light connected/loosely connected/Inactive mode and/or a connected/fully connected/Active mode. A WTRU in light connected mode may have a WTRU context stored in a RAN. A WTRU may perform an area monitoring procedure while in light connected state. A WTRU may engage in autonomous mobility during light connectivity. A WTRU may move within a logical area (e.g., a RAN paging area), perhaps without notifying the network. The WTRU may provide notice when it has moved outside a logical area (e.g., update RAN paging area). Mobility in light connected state may be network controlled (e.g., to enable handover when data transfer may be allowed and/or ongoing). A WTRU may be reachable during a light connectivity state. A WTRU may engage in autonomous mobility during light connectivity and/or an Inactive state.
Abstract:
Apparatuses and methods of flow-based processing is wireless systems are described. For example, in one method, a WTRU may determine that one or more data units correspond to a flow of such data units. The WTRU may perform such determination as a function of one or more matching rule(s). Flow-based processing may be enabled in the layer 2/layer 1 chain by per-packet determination using one or more rules, for example by routing through the applicable processing functions and/or using the applicable configuration and/or mapping to the applicable uplink physical layer functions and/or resources. One or more functions such as scheduling request, buffer status reporting, HARQ processing, and/or radio link failure and recovery may be controlled based on the policy associated with the flow corresponding to the data being processed.
