Assignee: GUANGDONG OPPO MOBILE TELECOMMUNICATIONS CORP., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A method for reporting information, comprising:
when a terminal device encounters abnormality during access to a network via a random access channel (RACH), storing, by the terminal device, resource information of the RACH; and
reporting, by the terminal device, the resource information of the RACH to a network device,
wherein the resource information of the RACH comprises contention free RACH resources used in the access of the terminal device to the network that has the abnormality and contention based RACH resources used in the access of the terminal device to the network that has the abnormality,
wherein the abnormality during the access of the terminal device to the network comprises:
the terminal device unsuccessfully attempts to access the network via contention free RACH resources and successfully attempts to access the network via other connection free RACH resources or contention based RACH resources, and
when the terminal device accesses the network via contention free RACH resources, the terminal device switches to another beam within a time period less than or equal to a first threshold and radio link failure (RLF) occurs within a time period less than or equal to a second threshold,

wherein the resource information reported by the terminal device further comprises:
one or more synchronization signal block/channel state information reference signal (SSB/CSI-RS) indexes corresponding to RACH resources used in the access of the terminal device to the network that has abnormality; and
measurement result of any one or more of reference signal received power (RSRP), reference signal received quality (RSRQ), and signal to noise ratio (SNR), of a cell or a beam, during the access of the terminal device to the network that has abnormality, and

wherein reporting, by the terminal device, the resource information to the network device comprises:
reporting, by the terminal device, the resource information to the network device when a number of times that the abnormality occurs reaches a third threshold.
