摘要 |
Briefly, in accordance with one or more embodiments, a conventional physical downlink control channel (PDCCH) is transmitted in a first region of a physical downlink control channel structure utilized by a remote radio head that has been assigned a cell identifier that is common to one or more other remote radio heads within the cell, and an enhanced physical downlink control channel (ePDCCH) is transmitted in a second region of the physical downlink control channel structure. |

1. An article of manufacture comprising a non-transitory storage medium having instructions stored thereon that, if executed, result in:
transmitting a physical downlink control channel (PDCCH) in a first region of a physical downlink control channel structure utilized by a remote radio head that has been assigned a cell identifier that is common to one or more other remote radio heads, or base station, or combinations thereof, within the cell; wherein the PDCCH is modulated with a common scrambling code, and wherein the common scrambling code is common to multiple remote radio heads, or a base station, or combinations thereof, within the cell; transmitting an enhanced physical downlink control channel (ePDCCH) in a second region of the physical downlink control channel structure; wherein the ePDCCH is transmitted in a simultaneous transmission mode, and wherein one or more remote radio heads transmits its own control channel in the simultaneous transmission mode on resources common to the one or more remote radio heads using scrambling sequences specific to respective remote radio heads; modulating demodulation reference signals with a specific scrambling sequence for said transmitting the enhanced physical downlink control channel; spatially precoding the demodulation reference signals prior to said modulating; and spatially precoding the enhanced physical downlink channel; wherein spatial precoding of demodulation reference signals is substantially similar to the spatial precoding of the enhanced physical downlink channel. |
