  • Patent number: 11943636
    Abstract: A method performed by a network node for beam management. The network node receives one or more quality values from a User Equipment (UE). The one or more quality values are measured by the UE on first reference signals transmitted by the network node in respective one or more beams in a first set of candidate beams. The A serving beam is selected out of the first set of candidate beams based on the received quality values for data communication with the UE. The network node creates a rule related to signal quality. The network node obtains one or more second quality values related to respective subsequent messages transmitted to the UE in the selected serving beam. As long as the rule is fulfilled with respect to the second quality value, the network node transmits one or more further subsequent messages only in the serving beam.

  • Publication number: 20230239655
    Abstract: A geofencing system (310) that does not rely on a GNSS or other like system. The geofencing system comprises a group of two or more fence-pole devices, FPDs, that define a geofenced area (399). Each FPD in the group is capable of making its own determination as to whether or not a certain communication device (377, 378) appears to be within the geofenced area. In one embodiment, if all of the FPDs have determined that the communication device appears to be within the geofenced area, then it is decided that the communication device is within the geofenced area. In another embodiment, if the group of FPDs consists of N FPDs and at least N?1 of the FPDs have determined that the communication device appears to be within the geofenced area, then it is decided that the communication device is within the geofenced area.

  • Publication number: 20220264320
    Abstract: A network node and a method for transmitting a Transmission Configuration Indication, TCI, update to a UE. The network node associates a first transmit beam with a first reference signal having first Quasi Co-Location, QCL, channel properties. The first transmit beam gives the same first QCL channel properties and is used in data transmission to the UE. Further, the network node determines second QCL channel properties given by a second transmit beam when a beam change is triggered. When the second QCL channel properties is within a QCL channel property range of a second reference signal and when the second reference signal has third QCL channel properties being different from the first QCL channel properties, the network node associates the second transmit beam with the second reference signal, and transmits, to the UE, a TCI update having an indication of the second reference signal.

  • Publication number: 20210306868
    Abstract: A method performed by a network node for beam management. The network node receives one or more quality values from a User Equipment (UE). The one or more quality values are measured by the UE on first reference signals transmitted by the network node in respective one or more beams in a first set of candidate beams. A serving beam is selected out of the first set of candidate beams based on the received quality values for data communication with the UE. The network node creates a rule related to signal quality. The network node obtains one or more second quality values related to respective subsequent messages transmitted to the UE in the selected serving beam. As long as the rule is fulfilled with respect to the second quality value, the network node transmits one or more further subsequent messages only in the serving beam.

  • Publication number: 20210234941
    Abstract: According to an aspect, a wireless device receives (302) a preview digital image from a computer server and applies object recognition processing (304) to the preview digital image, to determine (306) whether the preview digital image contains a representation of a known object of interest. Responsive to a positive determination, the wireless device transmits (308) an indication of the positive determination. The computer server sends, in response to the transmitted indication, an enhanced digital image corresponding to the preview digital image, or additional image data, which is received (310) by the wireless device. In the latter case, the wireless device forms an enhanced version of the preview digital image using the additional image data. The wireless device at least temporarily stores (312) the enhanced image or image version, e.g., for rendering on a display screen of the device.

  • Patent number: 10623080
    Abstract: There is provided mechanisms for adapting which beam to use for reception of signals. A method is performed by a receiving radio transceiver device. The receiving radio transceiver device is capable of receiving the signals using at least one beam selected from a set of beams. Each beam in the set of beams has a backup beam. The method includes receiving signals from a transmitting radio transceiver device while using a first beam selected from the set of beams. Signal receipt at a decreasing quality level while using the first beam is detected. The decreasing quality level is caused by interfering transmission from another transmitting radio transceiver device. In response thereto, a temporary switch to the backup beam of the first beam is initiated, without performing any beam training, for continued reception of signals from the transmitting radio transceiver device.
