ENERGY PER RESOURCE ELEMENT RATIO FOR SYNCHRONIZATION SIGNAL BLOCK SYMBOLS

Abstract:

Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may identify an energy per resource element (EPRE) ratio between a synchronization signal block (SSB) symbol containing a primary synchronization signal (PSS) and an SSB symbol containing a secondary synchronization signal (SSS), a physical broadcast channel (PBCH), or both, based on an operating band for the UE, a bandwidth of the SSB symbol containing the PSS and the SSB symbol containing the SSB, the PBCH, or both. The EPRE ratio may be based on maximum regulatory equivalent isotropically radiated power (EIRP) limits, maximum regulatory power spectral density (PSD) limits for the band, or both. The EPRE ratios may be different for different SSB symbols, when different SSB symbols have different bandwidths. A base station may configure and transmit, and a UE may receive, the SSB according to the identified EPRE ratio.
