    Abstract: One aspect of the disclosure provides a method performed by a wireless device for performing handover from a source network node to a target network node. The method comprises: obtaining (1402) an indication of a round-trip time for transmissions to the target network node; initiating (1406) access to the target network node; and, subsequent to initiating access to the target network node, transmitting (1408) data to or receiving (1408) data from the source network node for a time window following initiation of access to the target network node. The time window has a duration of at least the round-trip time for transmissions to the target network node.

  • Publication number: 20220132348
    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.

  • Publication number: 20220124566
    Abstract: A method performed in a User Equipment, UE, for handling handover from a source access node to a target access node is provided. The UE receives (501) a handover command message from the source access node. The handover command message includes parameters required for deriving a security context associated with the target access node. The UE establishes (502) a radio connection with the target access node. When detecting (503) that a security context switching criterion is fulfilled, the UE stops (504) to use a security context associated with the source access node.

  • Publication number: 20220124565
    Abstract: A method performed by a User Equipment, UE, to perform handover from a source access node to a target access node is provided. The UE, the source access node and 5the target access node are operating in a wireless communications network. The UE receives (601) a handover command message from the source access node. The UE establishes (602) a target radio connection with the target access node, and determines (603) whether or not a source cell release criterion is fulfilled. When the source cell release criterion is determined to be fulfilled, the UE releases (604) a source radio 10connection with the source access node.

  • Publication number: 20220110037
    Abstract: A process allows a UE to acquire an SEN before accessing a target base station/node during a RACH-less handover. The SEN may be provided to the UE in various ways. For example, the SEN may be provided as part of a handover command message (e.g., RRCReconfiguration) or a master information block (MIB). In this manner, the UE acquires the SEN before accessing the target base station/node, which allows the target base station/node and the UE to effect certain timings for the handover. For example, the target base station/node and the UE may set time bounds in which the handover must occur. As another example, different types of uplink grants may be set.

  • Patent number: 11224071
    Abstract: Systems and methods for delivery of on-demand system information in a cellular communications network are disclosed. In some embodiments, a method of operation of a network node comprises transmitting, to a User Equipment (UE), minimum system information including a set of signal quality indication levels and corresponding random access parameter(s) and detecting a random access request from the UE that uses the random access parameter(s) configured for the signal quality indication level that corresponds to a signal quality level measured at the UE. The method further comprises deciding whether to deliver on-demand system information to the UE via a broadcast or dedicated signaling based on the signal quality level measured at the UE, broadcasting on-demand system information upon deciding to deliver on-demand system information via a broadcast, and delivering on-demand system information to the UE via dedicated signaling upon deciding to deliver on-demand system information via dedicated signaling.

    Abstract: Systems and methods for early measurement reporting with a Radio Resource Control (RRC) resume complete like message are disclosed. Embodiments of a method performed by a wireless device and corresponding embodiments of a wireless device are disclosed. In some embodiments, a method performed by a wireless device comprises receiving, from a network node, an indication with a first message to resume a connection with a target cell. The indication is an indication that the wireless device is to include measurements performed by the wireless device while in a dormant state with a second message that indicates that resuming of the connection with the target cell is complete. The method further comprises transmitting, to the network node, the measurements performed by the wireless device while in the dormant state with the second message.

  • 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.

  • Publication number: 20210367876
    Abstract: Embodiments herein relate to, e.g., a method performed by a user equipment, UE, for handling signal measurements. The UE determines whether one or more conditions are fulfilled for indicating that a radio condition is below a certain level. In response to determining that one or more conditions are fulfilled and thereby indicating the radio condition is below a threshold, the UE transmits a report with restricted content.

  • Publication number: 20210274334
    Abstract: A network node obtains (302) a message to be transmitted as a public warning system notification to multiple UEs, via one or more SIBs, and obtains (304) area information corresponding to the message. The area information indicates an area for which the message is relevant. The network node determines (306) how many SIBs are needed for transmitting the area information and segments (308) the message into a plurality of segments, based on how many SIBs are needed for transmitting the area information. The network node transmits (310) the message and the area information via SIBs, such that a segment of the message is included in each SIB and such that each portion of the area information included in a SIB is accompanied by a segment of the message. A UE receives the SIBs and assembles the message and area information, displaying the message if it is relevant.
