METHOD AND DEVICE FOR MAPPING RESOURCES OF DOWNLINK CONTROL CHANNEL

摘要

The present invention discloses a method and device for mapping resources of a downlink control channel. The method includes: sequencing resource element groups (REGs) of the downlink control channel; assigning sequence numbers in the sequence to Physical Downlink Control CHannel (PDCCH) data of the downlink control channel by using the mapping addresses of Physical Control Format Indicator CHannel (PCFICH) data of the downlink control channel and the mapping addresses of Physical Hybrid automatic repeat request Indicator CHannel (PHICH) data of the downlink control channel; and according to the order of the sequence numbers, obtaining the data of the downlink control channel corresponding to the sequence numbers, thereby implementing resource mapping of the downlink control channel. The present invention avoids buffering the PDCCH data and reduces storage and delay pressure.
