METHOD FOR UPDATING TERMINAL-CENTERED COVERAGE

摘要

Disclosed is a coverage setting method comprising detecting the generation of uplink data which is to be transmitted through uplink communication; transmitting an uplink data generation notification message for requesting an update of an uplink coverage to a BBU mapped to an RRU, if the uplink data is not capable of being transmitted by the RRU due to a state of the RRU being connected to a terminal, receiving, from the BBU, an RRC connection resetting message for indicating an addition of a connection with a new RRU for performing the uplink communication when it is determined that the uplink coverage of the terminal is to be updated by the BBU, and setting the connection with the new RRU to transmit the uplink data.

1. A method for updating UE-centered coverage in a cloud radio access network (C-RAN) deployment where a remote radio unit (RRU) and a baseband unit (BBU) are configured separately, the method comprising the steps of:
detecting an occurrence of an uplink data which will be transmitted through an uplink communication; transmitting, when the uplink data cannot be transmitted by an RRU connected to a UE due to a state of the RRU, an uplink data occurrence notifying message for requesting an update of an uplink coverage to a BBU mapped with the RRU; receiving, from the BBU, an RRC connection reconfiguration message for indicating an addition of a connection with a new RRU for performing the uplink communication as it is determined that the uplink coverage of the UE is to be updated by the BBU; and configuring a connection with the new RRU to transmit the uplink data.
