  • Methods And Arrangements For Measurement Based Mobility
    Publication number: 20190215737
    Abstract: The present disclosure relates to methods and arrangements for performing wireless device assisted handover form a source access node to a target access node. Performed in a wireless device, a method comprises performing (S31) one or more mobility measurements for corresponding candidate radio links and selecting (S32), from the one or more candidate radio links, an initial target link based on the performed one or more mobility measurements. A first radio link measurement report based on the one or more mobility measurements, identifying the initial target link is transmitted (S33) to a target node providing the initial target link, using a first radio link reporting mechanism. A second radio link measurement report for the one or more candidate radio links and based on the same one or more mobility measurements, is transmitted (S34) to the source access node using a second radio link measurement report different from the first radio link reporting mechanism.

  • Link switch in a wireless communication system
    Patent number: 10327183
    Abstract: A wireless device in a wireless communication system is configured to perform measurements on a set of candidate links for supporting a network node in the system to make a decision as to which of the candidate links is to be a target link for a link switch. The wireless device reports (e.g., at the physical layer) measured candidate links one link subset at a time in order of the wireless device's preference for the target link, until the wireless device receives a target indication signal indicating which of the candidate links in the set is to be the target link. Any given link subset reports one or more candidate links which the wireless device has measured for the decision. Responsive to receiving the target indication signal, the wireless device performs the link switch to the indicated target link.

  • Synchronization Signal Search
    Publication number: 20180227865
    Abstract: A wireless communication device in a cellular wireless communication system activates (402) radio receiver circuitry during repeated time windows. The repeated activation has a nominal repetition time interval, T, and each repeated time window has a window duration, DT. During each DT, detection (404) is made of a plurality of synchronization signals that are transmitted by a respective cell. Based on the detected synchronization signals, calculation (406) is made of a respective cell quality value. These calculated quality values are then provided (408) to a mobility process. Depending (410) on the calculated quality values and at least a first quality threshold, any of I and DT are adjusted (412).
