Method and apparatus for one cell operation with fast small cell switching in wireless communication system

摘要

A method of supporting fast sub-cell switching by a sub-cell included in a macro coverage in a wireless communication system is provided. The method includes receiving multiple pieces of feedback information on multiple sub-cells from a User Equipment (UE), extracting channel quality indicators from the multiple pieces of received feedback information, respectively, comparing values of the extracted channel quality indicators, and determining, based on a result of the comparison of the values of the extracted channel quality indicators, whether to perform fast sub-cell switching of the UE.

1. A method of supporting fast sub-cell switching by a sub-cell included in a macro coverage in a wireless communication system, the method comprising:
receiving multiple pieces of feedback information on multiple sub-cells from a User Equipment (UE); extracting channel quality indicators from the multiple pieces of received feedback information, respectively; comparing values of the extracted channel quality indicators; and determining, based on a result of the comparison of the values of the extracted channel quality indicators, whether to perform fast sub-cell switching of the UE, wherein the determining of whether to perform fast sub-cell switching of the UE comprises:
determining whether a channel quality indicator having a largest value among the extracted channel quality indicators is a channel quality indicator of a serving sub-cell of the UE; andwhen the channel quality indicator having the largest value among the extracted channel quality indicators is determined to be the channel quality indicator of the serving sub-cell of the UE, maintaining the serving sub-cell.
