  • Patent number: 11005704
    Abstract: A user equipment starts a first timer in response to detecting a physical layer problem with a radio link between the user equipment and a node of a cellular network. Responsive to detecting a handover measurement event, the user equipment also starts a second timer and sends a measurement report to the node.

  • Patent number: 11006302
    Abstract: A second device that is in communication with a first device receives transmissions of the first device and detects a SILENCE period status of the first device, which corresponds to a status wherein the first device has no speech samples to be transmitted towards the second apparatus. The second device determines the type of the received transmissions, counts the number of received transmissions of a first type, and times a time interval between the last received transmission of the first type and the last received transmission of a second determined type. At reception of a transmission of the first type, the second device detects whether the first device is in the SILENCE period status on an evaluation of the counted number of transmissions of the first type and the time interval of the last received transmission of the first type and the last received transmission of the second type.

  • Patent number: 11005701
    Abstract: According to a first aspect of embodiments herein, the object is achieved by a method performed by a User Equipment (UE) for monitoring a beam transmitted by a base station in a radio communications network. The base station is serving the UE. The UE monitors (1202) a reference signal related to the beam, from the base station. Each time a quality of the reference signal is below a first threshold, the UE generates (1203) an Out-Of-Synchronization (OOS) event When the number of OOS events reaches an OOS Beam Failure Detection (BFD) threshold, the UE triggers (1205) a beam recovery preparation procedure, and when the number of OOS events reaches an OOS Radio Link Monitoring (RLM), threshold, the UE starts (1206a) an RLF timer.

  • Patent number: 11003252
    Abstract: A method of capturing haptic content of an object where the capturing involves a plurality of communication devices includes recognizing haptic content captured by a first communication device and properties associated with the captured haptic content and recognizing properties associated with a second communication device, and determining, at least partly based on the recognized properties, whether or not the second device is to participate in the capturing of the haptic content. If such a participation is determined, a transmission of at least parts of the haptic content captured by the first communication and the associated properties to the second communication device is initiated. Haptic content captured by the second communication device is then recognized by the haptic device, and a combination of the haptic content captured by the first communication device with the haptic content captured by the second device, can then be initiated.
