The An can antenna port be used is defined to make the channel over which a symbol on the can antenna port be used is conveyed can be inferred from the channel over which another symbol on the same can antenna port be used is conveyed.
thank you

The antenna ports is logical port, it is in the physical layer has been abstraction of the physical channel model defined from a particular transmitting antenna (logically) to the receiving antenna (logically) (SISO or MIMO a LINK), the implicit assumption of two symbols within the channel coherence time, sent from the port to receive port channel is high, or the time invariant, is logical, is this port in physics may be a set of physical antenna ports (such as defined by the particular precoding vector emission signal, this group of physical antenna is generally assume that time synchronization, unified calibration) through the composite response after the channel, under the baseband model is a channel,CodePudding user response:
Still don't understand the
CodePudding user response:
Here mean, antenna port is defined as a characterized by certain characteristic signal channel. When through characteristic signal acquisition channel response, will be able to get on the channel transmission of data.CodePudding user response:
