(2) Transmission/ Reception Point (TRP) spectrum efficiency. Transmission / Reception Point spectral efficiency is defined as an aggregate throughput of all users divided by the channel bandwidth divided by the number of transmission/reception point.
Read moreWhat is layer mapping in 5G?
The NR symbol modulate function implements modulation for 5G NR in one simple call. 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.
Read moreHow many subcarriers are in 5G?
5G NR can choose subcarrier spacing from 15kHz to 240kHz, with a maximum 3300 subcarriers in simultaneous use on one channel . However, channels can be no more than 400MHz wide. The standard is frequency agnostic, meaning any subcarrier configuration can be used on any band.
Read moreWhat is 5G physical layer?
PHY layer sits at the bottom of the 5G NR protocol stack, interfacing to MAC sublayer higher up via transport channels . It provides its services to MAC and is configured by RRC . PHY supports downlink ( gNB -to- UE ), uplink ( UE -to- gNB ) and sidelink ( UE -to- UE ) communications.5 Nis 2021
Read moreWhat is physical layer in LTE?
LTE Physical layer eNodeB Transmitter eNodeB Physical layer consists of Channel coding,rate matching, scrambler, mapper, layer mapping, pre-coding, resource element mapper, ofdm module . CRC is appended to the data from MAC layer before being passed through the PHY layer.
