According to the Blind handover or blind redirection method and system, A3 is the event that is used by the gNodeB to trigger a blind redirection procedure. A3 is defined as “neighbour becomes offset better than serving” in 3GPP TS 38.331. When the gNodeB detects that the UE’s signal quality on a neighbouring cell is better than that on the serving cell by a certain offset, it can initiate a blind redirection procedure to switch the UE to the neighbouring cell without requiring measurement reports from the UE.

According to the Huawei Releases 5G Series Products, Huawei’s AAU5313 and AAU5613 are both RF modules that support 64T64R. The AAU5313 is an ultra-wideband Massive MIMO product that supports both 64T64R and 400 MHz bandwidth on the C-band. The AAU5613 is a BladeAAU Pro product that supports 64T A+P integration on sub-3 GHz bands. The AAU5612 is a BladeAAU product that supports only 32T A+P integration on sub-3 GHz bands. The RRU3939 is not an AAU product but an RRU (Remote Radio Unit) product that supports only 8T8R on sub-3 GHz bands.

According to the HCIA-5G V2.0 Exam Outline, cell unavailability due to system faults (specified using N.Cell.Unavail.Dur.System) is caused by factors such as CPRI link faults, board faults, and faults on an RF module’s TX or RX channels, which correspond to options A, C, and D. Blocking cells by using MML commands is not a system fault, but a manual operation, which corresponds to option B.

According to the HCIA-5G V2.0 Exam Outline, handover execution failures can use the counters to collect failure reasons in SA networking, which corresponds to option A. The counters include N.HO.Exec.Fail.RadioResFail, N.HO.Exec.Fail.TAExceed, N.HO.Exec.Fail.NoRespFromUE, and N.HO.Exec.Fail.Other.
