Patent ID: 8526414

Claim:
A method of transmitting physical control format indicator channel (PCFICH) symbols in a downlink subframe to a user equipment (UE), the method comprising: mapping 16 PCFICH symbols to four resource element groups (REGs) in a first OFDM symbol of the downlink subframe; and transmitting the mapped 16 PCFICH symbols, wherein the four resource element groups comprises a first resource element group including first four resource elements, a second resource element group including second four resource elements, a third resource element group including third four resource elements and a fourth resource element group including fourth four resource elements, wherein first resource elements from the first four resource elements, the second four resource elements, the third four resource elements and the fourth four resource elements have positions given by: K 0 , K 0 +└N RB DL /2┘*N SC RB /2, K 0 +└2N RB DL /2┘*N SC RB /2, and K 0 +└3N RB DL /2┘*N SC RB /2, respectively, wherein K 0 is determined as (N SC RB /2)*(N ID cell mod 2N RB DL ), wherein ‘N RB DL ’ indicates a number of resource blocks transmitted in a downlink, wherein ‘N SC RB ’ indicates a number of resource elements per a resource block in the frequency domain, and wherein ‘N ID cell ’ is a physical layer cell identifier.
