内容摘要
《4G LTE-Advanced Pro和通向5G之路(第3版 影印版 英文版)》: In general, it is important for a device to understand what it can assume in terms of the relation between the radio channels experienced by different downlink transmissions.This is,for example, important in order for the device to be able to understand what reference signal(s) should be used for channel estimation for a certain downlink transmission.It is also important in order for the device to be able to determine relevant channel—state information,for example, for scheduling and link—adaptation purposes. For this reason,the concept of antenna port has been introduced in the LTE specifications,defined such that the channel over which a symbol on the antenna port is conveyed can be inferred from the channel over which another symbol on the same antenna porr is conveyed.Expressed differently, each individual downlink transmission is carried out from a specific antenna port, the identity of which is known to the device.Furthermore, the device can assume that two transmitted signals have experienced the same radio channel if and only if they are transmitted from the same antenna port. ……
