What is antenna port mapping?
The antenna mapping jointly processes the modulation symbols corresponding to the one or two transport blocks and maps the result to the set of antenna ports to be used for the transmission.
What are antenna ports in 5G?
The concept and definition of Antenna Ports are same as LTE Antenna Ports. It is defined as follows (38.211-4.4. 1). An antenna port is 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 port is conveyed.
What is layer mapping in 5G?
Layer mapping is the operation that maps one or two codewords to up to eight layers. This operation is somewhat simplified compared to LTE, where you could see one or two codewords for a given number of layers. In 5G NR, as mentioned earlier, anything up to four layers uses a single codeword.
How many ports does an antenna have?
Various configurations are defined that use these C-RS antenna ports, including 2- or 4-port Tx Diversity and 2-, 3-, or 4-port Spatial Multiplexing.
