Title:
SYNCHRONIZATION SIGNAL FORWARDING TIMING AND SSB TRANSMISSION POSITIONS FOR NETWORK CONTROLLED REPEATERS (NCR)
Document Type and Number:
WIPO Patent Application WO/2024/014227
Kind Code:
A1
Abstract:
A network controlled repeater (NCR) is described. The NCR may include receiving circuitry configured to detect and receive system information including synchronization signal block (SSB) configuration from a gNodeB (gNB), receive side information with NCR SSB forwarding timing from the gNB, and receive side information on SSB positions for NCR SSB transmissions. The NCR may also include transmitting circuitry configured to determine the SSB positions for NCR SSB transmission, regenerate the SSB with NCR SSB indexes, and transmit the SSBs in the determined SSB positions with corresponding NCR beams, and not transmit in the remaining SSB positions in the synchronization signal (SS) burst set.
