Methods and Apparatus for Resource Element Mapping

摘要

Improved mechanisms for using enhanced physical downlink control channel (EPDCCH) and enhanced physical hybrid indicator automated repeat request indicator channel (EPHICH) resources are described. A physical resource block (PRB) of an EPDCCH is specified and one or more EPHICH code blocks, which may also be referred to as an EPHICH resource element group (EPREG), are defined. One or more of the EPREGs is mapped into the EPDDCH PRB.

1. An apparatus comprising:
at least one processor; memory storing a program of instructions. wherein the memory storing the program of instructions is configured to, with the at least one processor, cause the apparatus to at least: define one or more physical resource blocks (PRBs) of an enhanced physical downlink control channel (EPDCCH); define one or more enhanced physical hybrid automatic repeat request indicator channel (EPHICH) groups each comprising one or more EPHICH resource element groups (EPREGs); and map the one or more of the EPREGs into the said one or more PRBs of the EPDCCH, with EPREG to resource element (RE) mapping within one PRB of the EPDCCH being accomplished according to a predefined allocation order.
