Methods and apparatus in a fifth-generation wireless communications network, including an example method, in a wireless device, that includes determining a reporting quality threshold for a parameter related to channel state information (CSI); performing a measurement for each of a plurality of beams from a first predetermined set of beams for evaluation; evaluating the measurement for each of the plurality of beams against the reporting quality threshold; discontinuing the performing and evaluating of measurements in response to determining that the reporting quality threshold is met for one of the beams, such that one or more beams in the first predetermined set of beams are not measured and evaluated; and reporting, to the wireless communications network, CSI for the one of the beams.

Network architecture, methods, and devices for a wireless communications network

Systems and methods are disclosed herein for output pacing in a cellular communications system that serves as a virtual Time-Sensitive Networking (TSN) node in a TSN network. In some embodiments, a method of operation of a boundary node associated with a cellular communications system that operates as a virtual TSN node in a TSN network comprises receiving user plane traffic from a node in the cellular communications system. The user plane traffic is user plane traffic received by the cellular communications system from a previous hop TSN node. The method further comprises performing output pacing for the user plane traffic when outputting the user plane traffic to a next hop TSN node such that the user plane traffic is output to the next hop TSN node at a rate that matches a desired rate at the next hop TSN node. Corresponding embodiments of a boundary node are also disclosed.

Output pacing in a cellular communications system serving as a time-sensitive networking (TSN) node

Systems and methods related to conveying Time Sensitive Networking (TSN) synchronization information within a cellular communication system (e.g., a Fifth Generation System (5GS)) are disclosed. In one embodiment, a method performed by a User Equipment (UE) in a cellular communications system or a TSN Translator (TT) associated with the UE comprises receiving, from a TSN end station, a Precision Time Protocol (PTP) or generalized PTP (gPTP) announce message comprising information that identifies one or more clock domains for which the TSN end station desires to receive PTP or gPTP messages. The method further comprises sending, to a core network node in the cellular communications system, either: (a) the information that identifies the one or more clock domains extracted from the PTP or gPTP announce message or (b) the PTP or gPTP announce message. Using this information, UE specific PTP or gPTP message filtering may be applied.

5G system signaling methods to convey TSN synchronization information

A wireless device, network node and methods using new radio time division duplex, NR-TDD, are provided. In one embodiment, the network node includes processing circuitry configured to configure placement of downlink control messages over at least two symbols of a NR TDD slot. The at least two symbols are different symbols in the time domain.

Control using NR TDD

A method may be performed by a network entity of a wireless communication network. A first PDU session may be established for a wireless terminal (UE) using a first NodeB base station (MgNB) and a first user plane function entity (UPF). A second PDU session may be established for the wireless terminal (UE) using a second NodeB base station (SgNB) and a second user plane function entity (UPF). The first and second PDU sessions may be established for the wireless terminal (UE) using the first and second NodeB base stations so that the first and second PDU sessions are provided concurrently using dual connectivity DC to provide redundant data paths for communication of data for the wireless terminal (UE) through the wireless communication network.

Methods providing dual connectivity for redundant user plane paths and related network nodes

Systems and methods related to Time-Sensitive Networking (TSN)-cellular communication system Quality of Service (QoS) mapping are disclosed. In some embodiments, a method performed for operating a cellular communications system as a virtual TSN node in a TSN system comprises, at a TSN application function, receiving one or more TSN QoS parameters for the virtual TSN node from a controller associated with the TSN system and providing the one or more TSN QoS parameters to a core network function in a core network of the cellular communications system. The method further comprises, at the core network function, receiving the one or more TSN QoS parameters, mapping them to one or more QoS policies and/or one or more rules in the cellular communications system, and applying the one or more QoS policies and/or the one or more rules in the cellular communications system.

TSN-cellular communication system QoS mapping and RAN optimization based on TSN traffic pattern related information

Methods and apparatus in a fifth-generation wireless communications, including an example method, in a wireless device, that includes receiving a downlink signal comprising an uplink access configuration index, using the uplink access configuration index to identify an uplink access configuration from among a predetermined plurality of uplink access configurations, and transmitting to the wireless communications network according to the identified uplink access configuration. The example method further includes, in the same wireless device, receiving, in a first subframe, a first Orthogonal Frequency-Division Multiplexing (OFDM) transmission formatted according to a first numerology and receiving, in a second subframe, a second OFDM transmission formatted according to a second numerology, the second numerology differing from the first numerology. Variants of this method, corresponding apparatuses, and corresponding network-side methods and apparatuses are also disclosed.

Systems and method are disclosed herein that relate to support for virtual Time-Sensitive Networking (TSN) bridge management, Quality of Service (QoS) mapping, and TSN related scheduling in a cellular communications system. In some embodiments, a method performed by one or more network nodes of a cellular communications system operating as a virtual TSN bridge of a TSN network comprises providing, to a controller associated with the TSN network, parameters that relate to capabilities of the virtual TSN bridge. The parameters that relate to the capabilities of the virtual TSN bridge comprise a first parameter that defines a clock accuracy of an entity in the cellular communications system that operates gating control for the virtual TSN bridge and a second parameter that informs the controller associated with the TSN network that the virtual TSN bridge or a particular egress port of the virtual TSN bridge is restricted to exclusive gating.

5G system support for virtual TSN bridge management, QoS mapping and TSN Qbv scheduling

In a mobile network, the transmission of downlink data blocks to one or more terminal devices is accomplished on the basis of a retransmission protocol with a first feedback time defining a time interval between transmission of a first data block and transmission of a first feedback message being different from a second feedback time defining a time interval between transmission of a second data block and transmission of a second feedback message. The first feedback message indicates whether the first data block was successfully received, and the second feedback message indicates whether the second data block was successfully received. A base station of the mobile network controls the terminal device to send the second feedback message on other resources than used for transmission of the first feedback message.

Retransmission protocol feedback handling with multiple feedback times

The present disclosure provides techniques for reducing latency of periodic URLLC transmission and other critical data transmission with low latency requirements. To support periodic URLLC traffic, SPS with repetition is used. Before synchronization is achieved, the base station sends to the UE an SPS configuration for a periodic uplink data transmission. When the starting time of the data transmission is not known, the base station over-provisions SPS resources for the periodic data transmission. Based on the timing of the data transmissions, the base station adjusts the timing of the SPS configuration.

Methods and apparatus for synchronizing critical data transmission

A method is performed by a network entity of a wireless communication network. A first PDU session is established for a wireless terminal (UE) using a first NodeB base station (MgNB) and a first user plane function entity (UPF). A second PDU session is established for the wireless terminal (UE) using a second NodeB base station (SgNB) and a second user plane function entity (UPF). The first and second PDU sessions are established for the wireless terminal (UE) using the first and second NodeB base stations so that the first and second PDU sessions are provided concurrently using dual connectivity DC to provide redundant data paths for communication of data for the wireless terminal (UE) through the wireless communication network.

According to certain embodiments, a method in a network node for delivering a time synchronization service comprises obtaining a timing accuracy threshold for a time synchronization service provided to a wireless device; determining, based on a first timing accuracy error at the network node and a second timing accuracy error between the network node and the wireless device, that a timing accuracy of the time synchronization service is equal or superior to the timing accuracy threshold, and transmitting the time synchronization service to the wireless device with a timing accuracy equal or superior to the timing accuracy threshold. The method further comprises, in response to determining that the timing accuracy of the time synchronization service is inferior to the timing accuracy threshold, reconfiguring the network node to improve the timing accuracy of the time synchronization service.
