Systems, methods, and instrumentalities (e.g. aspects of entities, interfaces and procedures in a wireless transmit/receive unit (WTRU) and/or network layers L1, L2, l3) are disclosed for low latency medium access control (MAC) protocol data unit (PDU) assembly in wireless systems, such as 5G flexible radio access technology (RAT) (5gFLEX). Latency may be reduced, for example, by WTRU determination of network transmission parameters and signaling prior to a transmission grant. A WTRU may receive a modulation and coding scheme (MCS), resource range, etc. prior to a grant, e.g., for use in future grants. Data blocks may be incrementally created/encoded prior to a grant. Data units may be segmented, assembled and multiplexed, for example, based on data block sizes that allow MAC and radio link control (RLC) processing prior to a grant. Flexible grant sizes may be provided for early generation of transport blocks before a grant. A minimum guaranteed transport block size (TBS) may be signaled to permit early generation of a MAC PDU. Transmission parameters may be selected prior to a grant, for example, using blind decoding or a DCI reception procedure.

Medium access protocol data unit assembly in wireless systems

Extended Reality (XR) applications may require high throughput and very low latency. New Radio (NR) Wireless receiver/transmitter units (WTRUs) running XR applications (XR-WTRUs) may be confronted with link failures when these applications are used in dense urban or indoor environments because of these devices operating in the millimeter band. Methods and devices are provided therefore for performing cell selection and beam management proactively to avoid link failure due to objects being in line of sight between the XR-WTRU and a network node with which it has established a connection. XR-WTRUs may therefore perform visual sensing that may enable visualizing current and future radio environment and using this information to prevent link failures by handing the XR-WTRU over to an alternative network node in line of sight of the XR-WTRU before the XR-WTRU is no longer in line of sight of the network node with which it has established a connection.

Methods, architectures, apparatuses and systems for extended reality-assisted radio resource management

Wireless transmit/receive units (WTRUs) may include unmanned aerial vehicles (UAVs). The WTRUs/UAVs may cooperate to exchange channel busy ratio (CBR) and/or CBR statistics of one or more (e.g., all) the carriers that the WTRUs/UAVs monitors with each other for carrier selection/carrier reselection. A network may provide one or more inputs on carrier selection. For example, a network may provide one or more inputs on carrier selection based on the congestion that the network infers (e.g., through the CBR measurements reported by the WTRUs/UAVs and/or through its own measurements). MAC/PHY layers may be configured to perform transmit adaptation during PDCP packet duplication. For example, the carrier aggregation capability of receivers may be considered to adapt the number of transmissions per carrier. Based on the carrier aggregation capability of the receivers, the number of transmissions at one or more (e.g., every) carriers may be optimized jointly across carriers.

Carrier aggregation for wireless transmit/receive unit

Physical layer processing and procedures for device-to-device (D2D) discovery signal generation and transmission and scheduling of D2D discovery signals are described. Detection and measurement of a D2D discovery signal, D2D signal identity management, and monitoring by a wireless transmit/receive unit (WTRU) of PDCCH for D2D discovery scheduling is described, as is a WTRU that may be configured with a D2D-specific transmission/reception opportunity pattern. The discovery signal may carry a payload for explicit information about user and/or service identity, and may be mapped to physical resources in such a way as to decouple transmission/reception of the discovery signal from downlink operations. A WTRU may measure a D2D discovery signal quality and report to the network.

Discovery signal generation and reception

A method and an apparatus for wireless transmission using multiple uplink carriers are disclosed. A wireless transmit/receive unit (WTRU) may transmit via a primary uplink carrier data, pilot and control channels for uplink transmissions on both uplink carriers, and transmit a data channel and a pilot channel via a secondary uplink carrier. Alternatively, the WTRU may transmit via a primary uplink carrier data, pilot, and control channels for uplink transmission on the primary uplink carrier, and transmit via a secondary uplink carrier data, pilot, and control channels for uplink transmissions on the secondary uplink carrier. Each uplink carrier may be associated with at least one specific downlink carrier such that the WTRU applies control information received on a downlink carrier to uplink transmissions on an uplink carrier associated with the downlink carrier on which the WTRU receives the control information.

Method and apparatus for transmitting data and control information on multiple uplink carrier frequencies

A method of positioning posterior resection guides in a three-dimensional coordinate system using robotic arms to perform partial knee arthroplasties comprises connecting a first tracking device for a surgical tracking system of the robotic arm to a femur, connecting a second tracking device for the surgical tracking system of the robotic arm to a tibia, manually positioning the tibia relative to the femur to a desired orientation to perform a posterior resection, manually determining a position for the posterior resection guide to perform the posterior resection, digitizing a reference point for the posterior resection guide in the three-dimensional coordinate system for a location of a feature of the posterior resection guide, moving the posterior resection guide to the location in the three-dimensional coordinate system with the robotic arm, and resecting a posterior portion of a condyle of the femur using the posterior resection guide to guide a cutting instrument.

Devices and methods for posterior resection in robotically assisted partial knee arthroplasties

Systems, apparatuses, and methods are disclosed for receiving downlink control information (DCI) that may include an indication of a reference measurement resource (RMR), receiving an indication of a measurement configuration, and receiving an indication of a feedback resource configuration. A measurement report based on the indication of an RMR, an indication of a measurement configuration, and an indication of a feedback resource configuration may be generated and may be transmitted to a network device.

Systems and methods for reference signal measurements in wireless systems

A reference jig comprises a base adapted to be secured to a distal end of a bone. An adjustment mechanism has a bracket, one or more rotational joints operatively mounting the bracket to the base, whereby the bracket is rotatable in two or more rotational degrees of freedom relative to the base, and one or more translational joints. A landmark alignment unit is operatively connectable to the bracket by the at least one translational joint, the landmark alignment unit having a bone alignment component configured to be aligned with at least one bone landmark.

Computer-assisted surgery system and method for orienting a knee implant

A receiver bandwidth adaptation for radio access technologies (RATs) may be for a New Radio (NR) or 5G flexible RAT. A WTRU control channel (e.g., receiver) bandwidth may change, for example, based on monitoring a downlink channel for an indication using a bandwidth (BW) associated with a first BW configuration. The indication may include a signal to change the receiver BW. The WTRU may change the receiver BW associated with the first BW configuration to a second BW configuration when the WTRU receives the indication on a downlink (DL) channel. The WTRU may perform one or more measurements associated with the second BW configuration in response to the change of the receiver BW to the second BW configuration. The WTRU may transmit measurement information to a network entity. The WTRU may receive a DL transmission from the network using the second BW configuration.

Receiver bandwidth adaptation

Methods and systems for operation in a wireless communication system are provided. A first transmission may be initiated using at least a first portion of physical layer resources. A second transmission may be initiated using at least a second portion of the same physical layer resources. The first transmission may be any one of a puncturing transmission, interfering transmission, delay-sensitive transmission, or short transmission. The second transmission may be an on-going transmission or a long transmission.

Methods for enhanced multiplexing in wireless systems

A transmitting wireless transmit/receive unit (Tx WTRU) may receive configuration information that indicates one or more parameters. The one or more parameters may be associated with resource selection. The Tx WTRU may determine a first resource selection window and a second resource selection window. The first resource selection window may be associated with an active time of a receiving wireless transmit/receive unit (Rx WTRU). The second resource selection window may be associated with an inactive time of the Rx WTRU. The Tx WTRU may determine a first number of candidate resources associated with the first resource selection window. The Tx WTRU may determine a first number of candidate resources associated with the second resource selection window. In examples, the Tx WTRU may increase the first number of candidate resources associated with the first resource selection window to a second number of candidate resources associated with the first resource selection window.

Partial sensing-based resource allocation

A computer-assisted surgery system for obtaining a distance between at least two fixed points relative to a bone comprises a first accelerometer unit located at a first fixed location on the bone, and producing first acceleration data during a movement of the bone. A second accelerometer unit is located at a second fixed location on the bone, and simultaneously producing second acceleration data during the movement. A gyroscope unit is fixed to the bone and simultaneously producing angular rates of change of said movement. A processor unit obtains the acceleration data and the angular rates of change for calculating the distance between the first fixed position and the second fixed position on the bone using a distance value of a distance vector between the accelerometer units. An interface outputs the distance between the first fixed position and the second fixed position relative to the bone. A method for calculating a distance between at least two points on a bone is provided.

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.
