摘要
說明書
As used herein, the terms “base station (BS),” “radio base station,” “eNB,” “cell,” “sector,” “cell group,” “carrier,” and “component carrier” may be used interchangeably. A base station may be referred to as a “fixed station,” “NodeB.” “eNodeB (eNB),” “access point,” “transmission point,” “receiving point,” “femto cell,” “small cell” and so on.
A base station can accommodate one or more (for example, three) cells (also referred to as “sectors”). When a base station accommodates a plurality of cells, the entire coverage area of the base station can be partitioned into multiple smaller areas, and each smaller area can provide communication services through base station subsystems (for example, indoor small base stations (RRHs: Remote Radio Heads)). The term “cell” or “sector” refers to part or all of the coverage area of a base station and/or a base station subsystem that provides communication services within this coverage.
As used herein, the terms “mobile station (MS)” “user terminal.” “user equipment (UE)” and “terminal” may be used interchangeably. A base station may be referred to as a “fixed station.” “NodeB,” “eNodeB (eNB),” “access point,” “transmission point,” “receiving point,” “femto cell.” “small cell” and so on.
A mobile station may be referred to, by a person skilled in the art, as a “subscriber station,” “mobile unit.” “subscriber unit.” “wireless unit.” “remote unit,” “mobile device,” “wireless device,” “wireless communication device,” “remote device,” “mobile subscriber station,” “access terminal,” “mobile terminal,” “wireless terminal,” “remote terminal,” “handset,” “user agent,” “mobile client,” “client” or some other suitable terms.
