Claim of US Patent No. 10,694,582

1. An apparatus for Radio Interface (RI) switching in a wireless communication network, the apparatus comprising:a plurality of RI ports, each connected to a node of either a Radio Equipment Control (REC) or a Radio Equipment (RE), wherein at least one REC and at least one RE are connected to the apparatus via the plurality of RI ports;
a processor configured to:
receive, from a radio network controller (RNC), information on an amount of minimal processing and transmission units of respective RI ports, and
calculate a mapping relationship based on the received information, wherein the mapping relationship indicates data mapping between one or more minimal processing and transmission units of the at least one REC and one or more minimal processing and transmission units of the at least one RE;
a storage configured to store the mapping relationship between the one or more minimal processing and transmission units of the at least one REC and the one or more minimal processing and transmission units of the at least one RE, wherein each of the one or more minimal processing and transmission units is an Antenna-Carrier (AxC); and
a switcher configured to switch data received at an RI port, of the plurality of RI ports, to another RI port, of the plurality of RI ports, based on the mapping relationship.
