A method, apparatus, and system for provisioning a device onto a network using a non-secure communication channel between the device and a provisioner is described. The provisioner receives a timestamp-based on-time password (TOTP), and a universal resource identifier (URI) from the device and provides the TOTP and an out-of-band (OOB) UUID to a remote server over a secure communication channel identified by the URI. The device is then provisioned onto a network based on comparisons of the UUID and the TOTP.

Systems and method are specified to improve the reception of UL transmission, for example in power or coverage limited situations. A WTRU may modify procedures to increase the available signal energy for reception at an eNB and/or to make more efficient use of the available signal energy at the receiver for processing UL transmissions. Example methods for increasing UL link coverage may include modifying HARQ timing (e.g., shorter HARQ), using longer TTIs, use of dedicated PUSCH allocations, use of new PUSCH modulations, enhanced reference signal design, UL macro diversity reception for PUSCH, utilizing protocol reduction techniques, ensuring in-order packet delivery, and/or utilizing a configuration for coverage limited/power limited modes of operation. The proposed methods may be applied individually or in any combination.

This disclosure provides systems, methods and apparatuses for performing ranging operations between a transmitting device and one or more receiving devices using one or more wireless channels. In some implementations, a transmitting device may substantially concurrently exchange, on each of a plurality of wireless channels, a corresponding set of FTM frames and acknowledgement (ACK) frames with a receiving device, and then determine a distance to the receiving device based on the plurality of exchanged sets of FTM and ACK frames. In some other implementations, the transmitting device may substantially concurrently exchange, with each of a plurality of receiving devices, a corresponding set of FTM frames and ACK frames on a corresponding one of a plurality of wireless channels, and then determine a distance to each of the plurality of receiving devices based on the corresponding sets of exchanged FTM and ACK frames.

A UE in idle mode may use a preconfigured uplink resource for transmission, retransmission, and/or HARQ. For example, the UE may store configuration data for a preconfigured uplink resource and an RNTI for idle mode communication. In idle mode, the UE generates an uplink transmission using the preconfigured uplink resource. After the uplink transmission, the UE starts a retransmission timer, and monitors PDCCH with the RNTI provided in the configuration data for HARQ ACK/NACK.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may use the techniques described herein to identify slots in which to transmit multiple sounding reference signal (SRS) resource sets triggered by one or more downlink control information (DCI) messages. In one aspect, the UE may determine a next available slot for transmitting an SRS resource set based on the available information at a timestamp and on a reference slot (e.g., the slot in which the latest DCI message is received or a slot that is offset from the slot in which the latest DCI message is received). In yet another aspect, the UE may receive one or more indications of slots in which to transmit the multiple SRS resource sets. In yet another aspect, the UE may follow one or more rules to identify slots in which to transmit the multiple SRS resource sets.

An information feedback method and apparatus are provided. The method includes: receiving a scheduling instruction from a base station that configures multiple unlicensed channel resources for a terminal, where the scheduling instruction carries information for the terminal to determine a first transmission position for feeding back a hybrid automatic repeat request (HARQ), and the first transmission position is on a first unlicensed channel resource; obtaining the first transmission position according to the scheduling instruction, and detecting whether the first transmission position is in an available state; when detecting the first transmission position is in a non-available state, determining a second transmission position for feeding back the HARQ, where the second transmission position is on a second unlicensed channel resource; and when detecting the second transmission position is in the available state, sending information on HARQ feedback to the base station at the second transmission position.

Embodiments of the present disclosure provide for configuration and use of preconfigured uplink resources.

A wireless device receives a radio resource control (RRC) reconfiguration message triggering a first active bandwidth part (BWP) switching of a first cell. Based on the triggering the first active BWP switching during a second active BWP switching of a second cell, the first active BWP switching is delayed until the second active BWP switching is completed.

Embodiments of this application provide a triggering method for a radio link failure and a device. The method includes: A first node obtains first indication information, where the first indication information includes a maximum quantity of hybrid automatic repeat request HARQ retransmissions performed by the first node on a second node, or a maximum quantity of times of HARQ NACKs that are sent by the second node and that are received by the first node; and the first node determines, based on the first indication information, whether a radio link failure occurs on a link between the first node and the second node.

A system for providing an enhanced acknowledgement (ENH-ACK) frame is configured to receive an incoming packet transmitted by an external device, determine that an ENH-ACK response is required based on a MAC header of the incoming packet schedule transmission of the ENH-ACK frame to the external device in accordance with a standard turnaround time limit relative to receipt of the incoming packet, determine contents of one or more packet processed fields of the ENH-ACK frame and populate the one or more packet processed fields, and complete transmission of the ENH-ACK frame with the populated packet processed fields.
