A METHOD FOR SIGNALING THE OVERLAP OF DOWNLINK CONTROL AND DATA CHANNELS |
摘要 |
<p>A network signals an allocation (PDCCH) for a downlink shared channel (PDSCH); and also signals an indication (reference signal RS) whether a resource block (PRB) comprising the allocated downlink shared channel is used for a control channel transmission (E-PDCCH). Examples include the E-PDCCH being time or frequency multiplexed with the PDSCH; and the indication being a different RS sequence (at least one element being phase shifted) than an original RS sequence used if the PRB were not used for the E-PDCCH. The UE tests for the phase shift by blind decoding. If the phase shift is present the UE a) decodes a portion of the PRB for data if the network is using TDM for its E-PDCCH/PDSCH multiplexing, orb) decodes the full PRB only for the E-PDCCH if the network is using FDM for its E-PDCCH/PDSCH multiplexing.</p> |
