GSM中可以基站可以通过BSIC来区分,但是LTE中的不同eNode B通过什么参数来判别呢?
还有同频和异频的基站区分参数呢?
小弟新手,还请各位大侠引导,谢谢!!

哪我怎么知道是同一个eNodeB中的cell还是不同eNodeB中的cell呢?

28bit里的前20bit是eNB代码,后8bit是同一eNB下的cell代码,所以就看前20bit是否一至就知道了

麻烦再告诉下3gpp哪里有相关的定义呢?谢谢~~

SIB1广播的是28bit的Cell Identity,包含了eNB ID。请参见下面的描述:
- E-UTRAN Cell Global Identifier (ECGI): used to identify cells globally. The ECGI is constructed from the PLMN identity the cell belongs to and the Cell Identity (CI) of the cell. The included PLMN is the one given by the first PLMN entry in SIB1.
- eNB Identifier (eNB ID): used to identify eNBs within a PLMN. The eNB ID is contained within the CI of its cells.
