A method and system to control anchor carrier configuration for dual-connectivity service of a user equipment device (UE), the dual-connectivity service including the UE being served concurrently by a master node (MN) over a first connection and by a secondary node (SN) over a second connection. An example method includes determining, when the UE has the first connection with the MN, that the UE is within threshold poor coverage of the MN. And the method includes selecting as the anchor carrier one of multiple carriers on which the MN provides service. Further, the method includes, based at least on determining that the UE is within the threshold poor coverage of the MN, basing the carrier selection on a transmission mode that the MN supports using on the selected carrier. And the method includes causing the selected carrier to be the anchor carrier for the dual-connectivity service of the UE.

A management system obtains, from a user device, information indicating a power measurement of a beam set that is utilized to communicate with the user device. The beam set includes one or more active beams, of a plurality of beams, that are associated with a single beam identifier. The management system identifies a location of the user device and thereby determines an expected power measurement of the beam set. The management system determines that a difference between the power measurement of the beam set and the expected power measurement of the beam set satisfies (e.g., is greater than or equal to) a difference threshold. The management system therefore causes the beam set to be modified. The management system may use a machine learning model (e.g., a neural network machine learning model) to facilitate modification of the beam set.

A terminal according to one aspect of the present disclosure includes a receiving section that receives a MAC control element (MAC CE) capable of specifying a plurality of transmission configuration indication (TCI) states for one control resource set, and a control section that controls reception of downlink control information transmitted from each of a plurality of transmission points by using a same control resource set, based on the MAC CE.

The invention relates to a method for classifying V2X messages and to a vehicle arranged to receive V2X messages and using the method to classify the received V2X messages. A method according to the invention for processing a message in a vehicle (100) comprises the steps of: receiving a signal (920) containing the message by means of a first antenna (111) and a second antenna (112); determining a relevance of the message (930) on the basis of signal characteristics and on the basis of navigation information of the vehicle (100); and processing the message with a ranking (940) corresponding to the determined relevance, wherein an attenuation map (300) assigns attenuation values to the vehicle environment on the basis of static objects (210) and dynamic objects (220) section by section. A vehicle according to the invention is arranged to use the relevance-based method for processing a message.

A wireless device receives one or more messages indicating a first transmission occasion for a physical uplink control channel (PUCCH) resource and indicating a second transmission occasion for the PUCCH resource. The wireless device receives downlink control information (DCI) indicating a transmission configuration indicator (TCI) state and indicating the PUCCH resource. The wireless device skips transmission, via the first transmission occasion of the PUCCH resource and based on a first listen before talk (LBT) procedure indicating a busy channel on the first transmission occasion, of an acknowledgment of the receiving the DCI indicating the TCI state. The wireless device transmits, based on a second LBT procedure indicating an idle channel on the second transmission occasion, the acknowledgment via the second transmission occasion of the PUCCH resource.

A base station and terminal use methods of obtaining synchronization and system information in a wireless communication system. An operation of a base station includes generating a synchronization signal to be transmitted through a Synchronization Channel (SCH), generating a broadcast signal to be transmitted through a Broadcast Channel (BCH), and transmitting repetitively the SCH and the BCH by performing beamforming on the channels with different transmission beams.
