Abstract: A system and method are provided to efficiently provide coverage within a large scale of a building by identifying user equipment (UE) on a floor by floor basis using a distributed antenna system (DAS) and pseudo timing advance values (TA) assigned to each floor. By applying different pseudo delays on a plurality of distributed antenna basis located at each floor, a base station can know a floor at which a user equipment is located through a timing advance value of the user equipment. When a traffic amount increases based on the measured traffic amount of each floor, the base station may increase a carrier and adjust an amplifier output on a floor by floor basis, thereby efficiently using power and maintaining a user's quality of experience (QoE).

Abstract translation: 提供了一种系统和方法，以便通过使用分配式天线系统（DAS）和/或分配给每个楼层的伪定时提前值（TA）来逐层地识别用户设备（UE）来有效地提供大型建筑物内的覆盖。 。 通过在位于每层的多个分布式天线基础上应用不同的伪延迟，基站可以通过用户设备的定时提前值知道用户设备所在的楼层。 当业务量基于每个楼层的测量业务量增加时，基站可以增加一个载波并且逐层地调整放大器输出，从而有效地使用电力并保持用户的体验质量（QoE）。

Abstract: A method for determining a root sequence index by a network management server, according to an embodiment of the disclosure, comprises the steps of: determining whether to reassign a root sequence index of a cell managed by a base station; when reassigning the root sequence index of the cell, determining the root sequence index to be reassigned to the cell on the basis of the number of handovers between the cell and adjacent cells of the cell; and transmitting the determined root sequence index to the base station.

Abstract: The present disclosure relates to a network information analysis in a wireless communication system, and an analysis method comprises the steps of: receiving information on channel quality measured by a terminal; and outputting information on whether a carrier aggregation (CA) coverage mismatch occurs at a location where the channel quality has been measured, which is determined on the basis of the information on the channel quality. Further, the present disclosure comprises other embodiments as well as the above-descried embodiment.
