Title:
SEARCH PROCESS FOR PHYSICAL DOWNLINK CONTROL CHANNELS IN A COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/062377
Kind Code:
A1
Abstract:
Provided are methods and apparatuses for a user equipment to decode over a first set of resources a Physical Downlink Control CHannel (PDCCH) of a first type and to decode over a second set of resources a PDCCH of a second type in a same transmission time interval, to perform a first search process for candidate PDCCHs of the first type over a first set of resources and to perform a second search process for candidate PDCCHs of the second type over a second set of resources, and to determine whether to include for data reception resources that are separately indicated for potential transmission of PDCCHs of the first or of the second type.
