Methods and apparatuses are provided for centralized radio access network (CRAN) scalability. In one embodiment, a network node includes processing circuitry configured to cause the network node to schedule at least one wireless device according to a radio resource partition, the radio resource partition representing a division of radio resources between at least two schedulers of a same cell, and each radio resource partition of the cell being assigned to a corresponding scheduler of the at least two schedulers; and receive, from at least one scheduler of the at least two schedulers, an indication of an amount of the radio resources that are scheduled by the at least one scheduler. In one embodiment, a network node includes processing circuitry configured to cause the network node to send, to a master scheduler, an indication of an amount of the radio resources that are scheduled by the network node.

Methods and apparatuses for supporting centralized radio access network (CRAN) scalability

According to one or more embodiments, a first network node of a first radio access technology, RAT, configured to communicate with a second network node of a second RAT different from the first RAT is provided. The first network node includes processing circuitry configured to: schedule a physical resource block, PRB, in a predetermined frequency carrier range where the scheduling starts from a predefined frequency location in the predetermined frequency carrier range, receive an indication that the PRB has been scheduled by the second network node, and responsive to the received indication, discard the PRB scheduled by the first network node if the PRB is located outside of a first predetermined partition of radio resources allocated to the first network node.
