EFFICIENT SIGNALING BASED ON ASSOCIATIONS OF CONFIGURATION PARAMETERS

Title:

EFFICIENT SIGNALING BASED ON ASSOCIATIONS OF CONFIGURATION PARAMETERS

Document Type and Number:

WIPO Patent Application WO/2019/140344

Kind Code:

A1

Abstract:

Disclosed are methods, devices and systems for addresses efficient signalling of the association between downlink signals (e.g. SS/PBCH (synchronization signal/physical broadcast channel) blocks (SSBs) or CSI-RS (channel -state information reference signal)) and physical random access channel (PRACH) resources. In some embodiments, the "number of SSBs per PRACH resource" parameter value is associated with the number of frequency multiplexed PRACH resources and/or the number of symbols in the PRACH preamble format. Embodiments of the disclosed technology enable more flexible random access configurations and allow a wider range of network implementations.
