Mobility synchronization measurements
First Claim
1. A method for handling mobility synchronization measurements, the method being performed by a wireless device, the method comprising the steps of:
- receiving, from a radio access network node, an indication to perform mobility measurements on a set of narrow transmission beams, wherein the set of narrow transmission beams to be measured is indicated by a shared unique identity, and wherein each of the narrow transmission beams has increased signal strength in a beam direction;
prior to performing mobility measurements on the set of narrow transmission beams, checking whether said shared unique identity has previously been stored by the wireless device, and when said shared unique identity has previously been stored by the wireless device;
performing mobility measurements on the set of narrow transmission beams based on previously stored synchronization information of the set of narrow transmission beams, wherein said synchronization information is identified by said shared unique identity,wherein the wireless device operates in a cellular communication network that comprises a plurality of radio access network nodes, wherein each of the radio access network nodes provides network coverage in a respective coverage region by transmitting narrow transmission beams in the respective coverage region.

Abstract
There is provided a method for handling mobility synchronization measurements. The method is performed by a wireless device. The method comprises receiving an indication to perform mobility measurements on a set of transmission beams associated with a unique identity. The method comprises checking if the unique identity has previously been stored by the wireless device. The method comprises, if the unique identity has not previously been stored by the wireless device, performing mobility measurements on the set of transmission beams to determine synchronization information of the set of transmission beams. The method comprises storing the unique identity and the synchronization information of the mobility measurements.
