Abstract

Disclosed are a terminal, which receives a downlink signal from a plurality of RRHs, transmits a random access preamble to any one target RRH in which the intensity of the received downlink signal among the plurality of RRHs is greater than or equal to a threshold value, receives a random access response message indicating that an uplink connection to a selected RRH will be configured on the basis of difference of a reception power of a random access preamble received by the target RRH and a reception power of a random access preamble which is overheard by a neighborhood RRH adjacent to the target RRH, and configures an uplink connection to the selected RRH, and an uplink connection configuration method thereof.

Description

technical field [0001] The present invention relates to a method of configuring an uplink connection of a terminal, an RRH, and a BBU in an environment where the RRH and the BBU are separately implemented. Background technique [0002] Radio Access Network (RAN) configurations have been changed such that various types of small cells, such as pico cells and femto cells, interact with macro cells. The RAN configuration means a heterogeneous cell configuration or a hierarchical cell configuration for small cell coexistence of low power / near field communication in addition to an existing macrocell-based homogeneous network. The purpose of the new RAN configuration is to increase QoE (Quality of Experience) by providing high data transfer rates to end users. [0003] In Small Cell Enhancement of E-UTRA and E-UTRAN Study Item (SI), which is one of the scope of the 3rd Generation Partnership Project (3GPP) standard, the enhancement of indoor / outdoor scenarios using low power nodes...
