Energy-efficient communications in systems with shared radio units

A non-transitory computer readable medium controlling operations of multiple distributed units (DUs) that share a radio unit (RU) in a radio access network (RAN), the non-transitory computer readable medium storing instructions that are executable by one or more computing devices, and upon such execution cause the one or more computing devices to perform operations comprising:

• transmitting to at least one DU of the multiple DUs scheduling information indicative of corresponding time and frequency at which the at least one DU can communicate with the RU;
• and
• transmitting to the at least one DU information configured to instruct the at least one DU to refrain from transmitting synchronization information.
