  • Patent number: 11968571
    Abstract: A method performed by a target node (111) in a communications network (100). The method is for handling reconfigurations of a User Equipment (UE) (120) during a conditional handover. The target node (111) has received a conditional handover request for the UE (120) from a source node (110) and has sent a handover request acknowledgement to the source node (110) based on a current configuration of the UE (120). The target node (111) performs (401) synchronization and random access with the UE (120) based on the UE configuration used for the handover request acknowledgement. The target node (111) obtains (403), after performing (401) the synchronization, information regarding an updated configuration of the UE (120). The updated configuration has taken place since the handover request acknowledgement was sent to the source node (110).

  • Patent number: 11968547
    Abstract: A base station or other network node configures a network transmission in dependence on a directional scanning reception ability of a wireless communication device targeted by the transmission. An example transmission configuration is selecting or restricting which Transmission/Reception Point to use for the transmission or selecting or restricting the beamforming configuration to use for the transmission. The device complements operations in the wireless communication network by indicating its directional scanning reception ability in initial signaling, such as used for random access, or in Radio Resource Control signaling, or both.

  • Publication number: 20240129986
    Abstract: According to an aspect, a user equipment, UE, in a suspended state in a Radio Access Network, RAN, in response to expiration of a first timer, transmits an RRCResumeRequest message. The UE receives a reject message in response to the RRCResumeRequest message. In response to the reject message, the UE starts a second timer and subsequently transmits a further RRCResumeRequest message. The further RRCResumeRequest message is received by the network during a period bounded approximately by the lesser of a duration of the second timer and a period of the periodic UE event and the greater of the duration of the second timer and the period of the periodic UE event.

  • Publication number: 20240121680
    Abstract: A method and a wireless device (100) for handling handover in a wireless network (102) from a source cell (104) to a target cell when the device has obtained and stored a handover configuration for at least one target cell X (106A-C). Upon detecting a communication failure, the wireless device (100) performs cell selection and initiates handover to one of the target cell(s) X when that cell was selected, by applying the stored handover configuration of the selected cell. When none of the target cell(s) X was selected in the cell selection, the wireless device (100) initiates an RRC re-establishment procedure.

  • Patent number: 11956660
    Abstract: Systems and methods for triggering measurements before the completion of connection resumption are provided. In some embodiments, a method performed by a wireless device for performing measurements where a current Radio Resource Control (RRC) status is: IDLE or INACTIVE. The method includes monitoring for a potential reception of a downlink message in a cell that the wireless device is camping on; detecting, based upon the reception of the downlink message, information regarding performing measurements; performing measurements based on the information regarding performing the measurements; and reporting the measurement results. In some embodiments, the message is a paging message or a message multiplexed with the paging message. In this way, latency might be reduced to start performing measurements.

  • Patent number: 11916724
    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 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 an Out-Of-Synchronization (OOS) event. When the number of OOS events reaches an OOS Beam Failure Detection (BFD) threshold, the UE triggers a beam recovery preparation procedure, and when the number of OOS events reaches an OOS Radio Link Monitoring (RLM), threshold, the UE starts an RLF timer.
