  • Publication number: 20210058772
    Abstract: In order to ensure that a Subscription Concealed Identifier, SUCI, is calculated in the Universal Subscriber Identity Module, USIM, part of a User Equipment, UE, when intended, when a SUCI-Calculation-Indicator is set to a value indicating that the SUCI should be calculated in the USIM, a network node sets proprietary information, which is not known to a Mobile Equipment, ME, part of the UE, as required for calculation of the SUCI. The USIM facilitates calculation of the SUCI in the ME part of the UE only when the SUCI-Calculation-Indicator is set to a value indicating that the SUCI should be calculated in the ME. When the SUCI-Calculation-Indicator is set to a value indicating that the SUCI should be calculated in the USIM, the ME part deletes any locally stored information required for calculation of the SUCI.

  • Patent number: 10932211
    Abstract: Among other things, the method and apparatus examples herein provide a solution to the problems that arise regarding the need for a wireless device (50) to achieve source synchronization in a beam-based system, where the wireless communication network (20) does not define “cells” for connected-mode wireless devices (50). The problems relate to how a wireless device can re-synchronize with its source access node in a beam-based system that mainly relies on self-contained transmissions from transmission points (30) in the network (20). As one example advantage, the contemplated methods and apparatus enable wireless devices (50) to perform measurements to support mobility procedures even when no data transmissions are scheduled.

  • Patent number: 10931409
    Abstract: Systems and methods for determining configurable timing relationships and operational parameters are provided. In some embodiments, a method of operation of a wireless device in a wireless system includes determining round-trip propagation delay information between the wireless device and a network node. This round-trip propagation delay information may be a round-trip propagation delay a quantized round-trip propagation delay, or any other value indicative of the round-trip propagation delay. The in method also includes determining a Hybrid Automatic Retransmission Request (HARQ) operational parameter based on the round-trip propagation delay information between the wireless device and the network node. In this way, HARQ is extended to work for deployments with large round-trip propagation delays, such as satellite systems. This may increase the throughput and reliability of data transmission.

    Abstract: One or more nodes transmit CSI-RS symbols in a set of N CSI-RS elements, each CSI-RS element in the set corresponding to at least one resource element in a time-frequency grid of resource elements. The nodes select, from the N CSI-RS elements, a first set of CSI-RS elements to be measured by a first wireless device, the first set comprising one or several of the N CSI-RS elements. The nodes also transmit, to the first wireless device, a message comprising a first K-bit indicator identifying the first set of CSI-RS elements, wherein K<N. The nodes then receive a measurement report. The first K-bit indicator is one of a predetermined set of K-bit indicators, where each member of the predetermined set of K-bit indicators uniquely corresponds to a CSI-RS element or group of CSI-RS elements from among the N CSI-RS, according to a predetermined mapping.
