mib incorporated

Linux SNMP field. For some devices, the default public can work, but this setting may be disabled, adjusted, or protected for security and confidentiality reasons. Read your device or program documentation. Next, a parameter called OID is used to represent the object identifier. It seems confusing when I first started learning Linux SNMP. When you see the MIB management information base, it is not that difficult.

sequence index number within the group. The range of N_seq_phich is 0,1,..,7 (downstream normal CP) or 0,1,2,3 (Downlink extended CP), i.e., for normal CP, A Phich group can contain up to 8 different Phich channels, and for extended CP, a Phich group may contain up to 4 different Phich channels .So how many Phich groups are allowed in a system bandwidth? The protocol uses N_group_phich to represent the number of groups in the PHICH group, so the N_group_phich range is 0,1, ...,n_group_phich-1.
