  • Transmission system control
    Patent number: 12335864
    Abstract: A control system is configured to control a transmission system (12). The control system may be configured to, responsive to the occurrence of a condition for the transmission system (12) to exit a sleep state (12S), trigger the transmission system (12) to transition from the sleep state (12S) to an active state (12A). The control system may be further configured to control the transmission system (12) to transmit during at least a fraction of a transition period (12P) over which the transmission system (12) transitions from the sleep state (12S) to the active state (12A). Such control may for instance control the transmission system (12) to transmit, during the at least a fraction of the transition period (12P), in compliance with relaxed component performance requirements that are relaxed with respect to the component performance requirements with which the transmission system (12) is configured to transmit during the active state (12A).

  • Methods, network node and wireless device for verification of broadcast messages
    Patent number: 12323806
    Abstract: Embodiments herein relate to a method performed by a network node for enabling verification of a broadcast message transmitted from the network node to a wireless device. The network node signals a first public key, to the wireless device, using a secure connection. The network node further transmits a first broadcast message protected by a signature. The signature is generated from at least a protected part of the first broadcast message using a first private key, the first private key being associated with the first public key. Thereby, the broadcast message can be verified by the wireless device using the distributed first public key, thus preventing fake broadcast messages to be accepted by the device.

  • USING AN UPLINK GRANT AS TRIGGER OF FIRST OR SECOND TYPE OF CQI REPORT
    Publication number: 20250151071
    Abstract: Channel state feedback is provided from a UE to a base station as a first, detailed or a second, less detailed type of channel state feedback information. Initially it is determined whether the UE has received an uplink grant from the base station or not. If the UE has received an uplink grant, a first type of channel state feedback information is transmitted to the base station on the granted resource. If, however, the UE has not received an uplink grant, a second type of channel state feedback information is transmitted to the base station. Different types of channel state feedback information enables a UE and an associated base station to use available resources more efficiently, when requesting for and delivering channel state feedback information.
