name: NR-PSS
full_form: New Radio-Primary Synchronization Signal
context: NR synchronization signal is based on CP-OFDM. NR defines at least two types of synchronization signals; NR-PSS and NR-SSS. NR-PSS is defined at least for initial symbol boundary synchronization to the NR cell. NR-SSS is defined for detection of NR cell ID or at least part of NR cell ID. The number of NR cell IDs is targeted to be approximately 1000. NR-SSS detection is based on the fixed time/frequency relationship with NR-PSS resource position irrespective of duplex mode and beam operation type at least within a given frequency range and CP overhead. At least, normal CP is supported for NR-PSS/SSS. The raster for NR synchronization signals can be different per frequency range. At least for frequency ranges where NR supports a wider carrier bandwidth and operation in a wider frequency spectrum (e.g. above 6 GHz), the NR synchronization signals raster can be larger than the 100 kHz raster of LTE. When the synchronization signal bandwidth is the same as the minimum system bandwidth for
description: New Radio-Primary Synchronization Signal (NR-PSS) is a technology used in 5G New Radio (NR) systems for initial symbol boundary synchronization to the NR cell. It is one of the two types of synchronization signals defined in NR, the other being NR-Secondary Synchronization Signal (NR-SSS).
explanation: The context describes NR-PSS as a technical element within 5G NR systems, responsible for synchronization. This function and its role in a telecommunications standard clearly place it under the category of Technology.
