1. A base station configured to:

  • communicate through an enhanced distributed antenna system (eDAS) comprising a plurality of geographically-separated antenna nodes wherein each of the antenna nodes have a plurality of antenna elements;

    perform physical-layer baseband processing for each of the antenna nodes at a centralized processing location;

    cause the antenna nodes to transmit reference signals in accordance with a multiplexing scheme to allow user equipment to perform channel estimation for the antenna elements of any one or more of the antenna nodes; and

    cause the antenna nodes to transmit signals having synchronization codes to allow the user equipment to synchronize with the antenna elements of any one or more of the antenna nodes,wherein the synchronization codes are at least one of;

    partitioned to include information fields to uniquely identify a paging group, the base station, and the antenna node, andconfigured to have a code structure having a code space that is divided into a plurality of subspaces to allow the user equipment to uniquely identify the paging group, the base station and the antenna node.
