Embodiment Construction

[0050] In the following, the features and aspects of the present invention are also described with respect to the handover process. However, these features should also be understood as useful or used in a wider range of wireless resource comparison evaluation techniques that are not related to handover. In one embodiment, the latter can be understood as the preparation phase of the former.

[0051] figure 1 A plan view shows a scene where the present invention exerts its effects. figure 1 It can be understood as a floor plan of a cell. There are various nodes 11, 12, 13, 14 in the cell. Some or all of them may be fixed. The nodes 11, 12, and 13 are adapted to emit beams 21, 22, 23, that is, directional wireless transmission, while the node 14 emits non-directional transmission as shown by the dotted circle 24, which is called "broadcast". 10 indicates a UE that has or needs a wireless connection to the network. 20 indicates the trajectory of the UE.

Abstract

A method for comparative radio resource evaluation comprises the steps of assessing quality metrics of dedicated RACH resources carried by a beam and assessing quality metrics of common RACH resourcescarried by a beam, comparatively evaluating the assessed quality metrics of the resources, and storing or transmitting the comparative evaluation result or taking further measures in accordance withthe comparative evaluation result.

Description

Background technique [0001] In modern cellular systems such as LTE or LTE-A (Long Term Evolution, Long Term Evolution Advanced) and the future 5G NR (Fifth Generation New Air Interface), the handover process is used to connect user equipment (UE) with the current (serving) network node Disconnect the currently used radio resources and connect the UE with the new radio resources from the new (target) network node. [0002] Before the UE can start to use the new radio resources allocated from the target network (NW) node, a synchronization process and a random access process need to be performed. After the UE has synchronized with the target NW node, the UE can receive and send bits between the UE itself and the NW node. Then, the UE can start a random access procedure to the target cell. [0003] After synchronization, the random access process on the Random Access Channel (RACH) can be contention-based or non-contention, depending on whether the access process uses public or dedic...
