`ABSTRACT
`The present disclosure provides a communication method,
`
`
`
`
`
`
`
`
`base station and user equipment for configuring a parameter
`
`
`
`table in a wireless communication system including a base
`
`
`
`station and a user equipment, the communication method
`
`
`
`comprising: defining at both the base station and the user
`(2009.01)
`
`
`
`
`equipment a parameter table which includes whole entries of
`(2006.01)
`
`
`
`
`a legacy parameter table and extended entries; and trans­
`
`
`
`
`mitting from the base station to the user equipment a bitmap
`(Continued)
`
`
`
`
`indication which indicates a sub-table selected from the
`(52)U.S. Cl.
`
`
`
`
`
`parameter table, wherein the number of the entries in the
`CPC ........... H04W 721042 (2013.01); H04L 11003
`
`
`
`
`
`
`sub-table is the same as in the legacy parameter table.
