Patent attributes
Examples of distributed base station functionality in a telecommunication system (e.g., a distributed antenna system) are disclosed. In some aspects, the telecommunication system can include an interface with circuitry configured to communicate with one or more base-station entities, base-station components (such as baseband units or remote radio heads), or core-network entities. The telecommunication system can also include radio units that are positioned in an area for providing wireless coverage to terminal devices. The telecommunication system can also include a head-end unit that is communicatively coupled between the interface and the radio units. One or more devices in the telecommunication system can include a low-layer processing module. In some aspects, the low-layer processing module can perform functionality of a secondary eNodeB, such as (but not limited to) radio transport layer processing. In additional or alternative aspects, the low-layer processing module can perform physical layer processing that is split between uplink physical layer processing and downlink physical layer processing and/or split between secondary and primary physical layer processing.
