Claim 26:
27. A system for use in a distributed radio access network (RAN), the system comprising:
a baseband unit (BBU) configured to facilitate communication between a core network and a cluster of remote radio units (RRUs) in the distributed RAN, wherein the system is configured so that the cluster of RRUs is used with the BBU to provide wireless service; and
a group of RRUs communicably coupled to the BBU by a fronthaul link;
wherein the system is configured to:
assign one or more RRUs, selected from the group of RRUs, to the cluster of RRUs based on one or more parameters;
perform at least a medium access control (MAC) protocol of the RAN; and
communicate over the fronthaul link with the cluster of RRUs;

wherein at least one of the RRUs of the group comprises a compound RRU that includes a plurality of logical RRUs, each of the plurality of logical RRUs configured to act as a respective separate RRU;
wherein said one or more RRUs assigned to the cluster includes at least one of the logical RRUs of the compound RRU; and
wherein each of the plurality of logical RRUs is configured to perform at least some layer one baseband processing for a wireless interface.
