AI Technical Summary

Problems solved by technology

As a result, measurements involving measurements of signals transmitted in the uplink when the UE is reading the SI (e.g. UE or eNodeB time difference measurements) may be degraded
In cases where UL restricted subframes (or time-frequency resources) are used for uplink measurements, the impact of autonomous gaps on measurements may be more severe
For example, collision or overlap of autonomous gaps with UL restricted subframes (or time-frequency resources) may lead to poor measurement performance

Embodiment Construction

[0055] In short, there are provided a method in a UE for performing measurements in a wireless communication network, a method in a serving network node for configuring measurements performed by the UE accordingly and a method in a target network node A method for enabling a UE to acquire SI, and a corresponding device. Corresponding UEs, serving network nodes and target network nodes are also provided.

[0056] The methods disclosed in this disclosure are more focused on describing heterogeneous deployments, which should not be considered as a limitation on the embodiments, nor should it be limited to the definition of 3GPP heterogeneous network deployments. For example, the method may also be well employed for legacy macro deployments and / or for networks operating more than one radio access technology, RAT. Furthermore, although the embodiments are mainly described for autonomous gaps created in the DL, the present invention can also be applied in the UL.

Abstract

Embodiments herein relate to User Equipment UE (1200), configured to perform measurements in a wireless communication network. The UE acquires system information SI of a cell during an autonomous gap, and performs at least one non-SI measurement related to a serving cell and / or one or more neighboring cells during a period including the autonomous gap. The embodiment also relates to a serving network node (1300), a target network node (1400) and corresponding methods.

Description

technical field [0001] The present disclosure relates to measurement in a wireless network, in particular, to a user equipment and a method thereof for acquiring system information and performing measurement in a wireless network. The present disclosure also relates to a network node and a method in said network node. Background technique [0002] Interest in deploying low-power nodes (e.g., pico base stations, home eNodeBs, relays, remote radio heads, etc.) to enhance macro network performance in terms of network coverage, capacity, and individual user service experience has gained momentum over the past few years. Continued to increase. At the same time, it has been recognized that there is a need for enhanced interference management techniques and cell association techniques previously developed for more homogeneous networks to address the problem of generating interference e.g. caused by significant transmit power variations between different cells . [0003] In the 3...
