Title:
PROVISION OF RACH RELATED INFORMATION FOR CONNECTION FAILURE DETECTION
Document Type and Number:
WIPO Patent Application WO/2020/159286
Kind Code:
A1
Abstract:
A method and apparatus for provision of random access channel (RACH) related information for connection failure detection in a new radio access technology (NR) is provided. For example, a first gNB receives, from a wireless device, random access channel (RACH) related information and cell information for a radio link failure (RLF), and transmis, to a second gNB, the RACH related information and the cell information for the RLF. For another example, a gNB central unit (gNB-CU) of a first gNB receives, from a second gNB, RACH related information and cell information for RLF, and transmits, to a gNB distributed unit (gNB-DU) of the first gNB, information for an RACH configuration based on the RACH related information and the cell information for the RLF.
