Abstract
An Open Radio Access Network Radio Unit (O-RU) including a Radio Frequency (RF) unit and a baseband unit, wherein: the baseband unit includes two or more digital signal processing units; the two or more digital signal processing units are configured to execute digital signal processing with respectively defined higher-level units; and the baseband unit is configured so as to be able to make some of the two or more digital signal processing units execute the digital signal processing and so as to be able to switch between the digital signal processing units that are made to execute the digital signal processing.
Claims11
An Open Radio Access Network Radio Unit (O-RU) comprising:
- a Radio Frequency (RF) unit;
- and
- a baseband unit, wherein:
- the baseband unit includes two or more digital signal processing units;
- the digital signal processing units are configured to execute digital signal processing with respectively defined higher-level units;
- and
- the baseband unit is configured to put some of the digital signal processing units in an operational state to execute the digital signal processing, put other some of the digital signal processing units in a rest state not to execute the digital signal processing and switch the digital signal processing units between the operational state and the rest state.
An Open Radio Access Network Radio Unit (O-RU) management method comprising:
- a process of generating, on a virtualization infrastructure of an O-RU, multiple digital signal processing units configured to execute digital signal processing with respectively defined higher-level units;
- a process of transitioning between states of the respective digital signal processing units so that the respective digital signal processing units are put in an operational state in which the digital signal processing can be executed or in a rest state in which the digital signal processing cannot be executed;
- initiating a radio communication process of the O-RU by a first digital signal processing unit that is in the operational state among the multiple digital signal processing units;
- receiving a state switching signal in the O-RU;
- switching between the operational state and the rest state in the first digital signal processing unit, which responded to the receiving of the state switching signal;
- switching between the operational state and the rest state in a second digital signal processing unit that is in the rest state and that is different from the first digital signal processing unit, among the multiple digital signal processing units, which responded to the receiving of the state switching signal;
- and
- initiating a radio communication process of the O-RU by the second digital signal processing unit that is in the operational state among the multiple digital signal processing units.
