Why a new control channel in LTE rel 11?
One of the major enhancements in 3GPP Release 11 is the introduction of a new downlink control channel, the Enhanced Physical Downlink Control Channel (EPDCCH). The standardization of the E-PDCCH was necessary to support new features like CoMP, downlink MIMO and the considered introduction of a new carrier type with 3GPP Release 12 all with the intention to support the following goals:
- Support of increased control channel capacity.
- Support of frequency-domain ICIC.
- Achieve improved spatial reuse of control channel resources.
- Support beamforming and/or diversity.
- Operate on a new carrier type and in MBSFN subframes.
- Coexist on the same carrier as legacy Rel-8 and Rel-10 devices.
