  • Publication number: 20200228931
    Abstract: A method and a user equipment (110) as well as a method and a radio network node (120) for multimedia broadcast service are disclosed. The radio network node (120) sends, on a physical downlink control channel of the carrier, downlink control information using a multicast network identifier. The downlink control information comprises a bit indicating whether or not at least two emergency notifications are broadcast on the carrier, and a notification relating to a change of a multicast channel of the carrier. The user equipment (110) receives, on a physical downlink control channel of the carrier, downlink control information using a multicast network identifier. The user equipment (110) behaves as if at least two fields relating to indication of said at least two emergency notifications are set to one in a paging message for the user equipment (110), when the bit is set to one. Corresponding computer program(s) (403, 603) and computer program carrier(s) (405, 605) are also disclosed.

  • Patent number: 10667160
    Abstract: A method performed by a wireless communications device for measurement reporting associated with a first wireless communications network to a network node operating in a second wireless communications network. The first and second wireless communications networks operate according to different RATs. The wireless communications device receives an indication of one or more radio access network nodes operating in the first wireless communications network, among which one or more radio access network nodes a mobility of the wireless communications device is restricted. The wireless communications device further determines which radio access network nodes operating in the first wireless communications network are to be used for measurement reporting to the network node, based on the indication of the one or more radio access network nodes among which the mobility of the wireless communications device is restricted in the first wireless communications network.

  • Patent number: 10659205
    Abstract: According to one aspect of the teachings herein, a base station (20) schedules the transmission of uplink reference signals by a wireless device (16) separately from scheduling uplink data transmissions by the device (16). The separate scheduling may be done at specific times, under specific conditions, and with respect to specific devices (16) or groups of devices (16). Separate scheduling allows, for example, the base station (20) to use smaller scheduling intervals that are possible when uplink reference signals are integrally included in any scheduled uplink data transmission. As a further advantage, the density or number of uplink reference signal transmissions by a given device (16) can be adapted, e.g., based on channel conditions, data transmission formats, etc.

  • Publication number: 20200100127
    Abstract: A radio network node (12) in a wireless communication network (10) configures a wireless device (30) to send a measurement report responsive a determination by the device (30) that its current network coverage condition matches a predefined coverage condition that is characteristic of airborne operation of the device (30) at the current location of the device (30). As advantageously recognized herein, the network coverage condition experienced by the wireless device (30) at its current location changes as it rises above ground level. By configuring die device (30) to send a measurement report when its network coverage condition satisfies a coverage condition that, for the current location of the device (30). is characteristic of airborne operation, the network (10) effectively defines a mechanism for detecting airborne operation of the device and making one or more control decisions for the device (30). e.g., to limit network interference experienced or caused by the device (30).
