  • Patent number: 11419015
    Abstract: A method is performed by a wireless device in a network. The wireless device detects a triggering event related to a procedure for a handover from a source network node to a target network node in which the wireless device relies on downlink beam selection. The wireless device determines measurement information to include in a message to send to the target network node. The measurement information is obtained by measuring one or more beams according to at least one of a radio link management configuration, a beam management configuration, and a measurement configuration. In response to detecting the triggering event, the determined measurement information in the message is sent to the target network node.

  • Publication number: 20220256445
    Abstract: A wireless device, UE, in a communication network receives satellite positioning information and a list of a plurality of different types of measurements to perform to find a public land mobile network, PLMN, to select. The UE performs the plurality of different types of measurements on a frequency associated with a found PLMN to generate a plurality of measurement results. The UE determines, based on the plurality of measurements results, whether a high-quality indication should be provided to a non-access stratum, NAS. Responsive to determining that the high-quality indication should be provided, the UE provides the high quality indication and an identification of the found PLMN to the NAS.

  • Publication number: 20210400556
    Abstract: A network node of a wireless communication network provides information to a User Equipment (UE) that allows the UE to adapt it radio measurements with respect to the network, to account for “link changes.” Link changes are service-link and/or feeder-link changes arising from motion by the satellite(s) included in the Radio Access Network (RAN) portion of the network. The UE uses the provided information to adapt its radio measurements in conjunction with the link changes. Among the several advantages of accounting for satellite link changes in the manner contemplated are any one or more of reduced signaling going between the UE and the network, reduced battery consumption at the UE, mitigation of the effects of the link changes on the radio measurements, avoidance of spurious measurements, and an effective “automation” of the timed changeover by the UE to new measurement configurations, coincident with the occurrence of link changes.

  • Patent number: 11191008
    Abstract: A network node (200), a wireless device (202) and methods therein, for communicating or obtaining system information. The network node (200) transmits (2:1) a System Information Block Type1, SIB1, message that includes at least one other SIB than SIB1 as an extension. The wireless device (202) reads (2:2) the at least one other SIB in the SIB1 if the wireless device (202) is capable of reading the extension in the SIB1 message. The network node (200) may further transmit (2:1) the at least one other SIB in a subsequent separate System Information message. The wireless device (202) is then able to read (2:4) the at least one other SIB in the subsequently received System Information message if the wireless device (202) is not capable of reading the extension in the SIB1 message. Thereby, if the wireless device is capable of reading the extension in the SIB1 message it will acquire the system information earlier than if the other SIBs are only transmitted in less frequent System Information messages.

    Abstract: According to some embodiments, a network node is operable to separately schedule radio transmissions per sub-subframe (SSF). A method in the network node comprises mapping a first demodulation reference signal (DMRS) to first resource elements in a first SSF. The first resource elements are associated with a first set of antenna ports. The method includes mapping a second DMRS to second resource elements in a second SSF. The second resource elements are associated with the first set of one or more antenna ports and precoding of the second DMRS differs from a precoding of the first DMRS. The method further includes scheduling a radio transmission during the first SSF precoded in accordance with the first DMRS, and scheduling a radio transmission during the second SSF precoded in accordance with the second DMRS. In particular embodiments, a subframe may comprise two, four, or eight sub-subframes.
