Patent ID: 8457022

Claim:
A method comprising: detecting start of a system information message transmission window; and assigning a redundancy version sequence at the start of the transmission window, wherein the assignment includes excluding one or more of the predetermined subframes in even-numbered radio frames if the subframes are within the transmission window, and wherein the assignment includes excluding uplink subframes and multi-cast subframes, and wherein the assignment ensures the redundancy version sequence is continuous over adjacent radio frames, and wherein the redundancy version sequence is calculated according to RV k = ⌈ 3 2 ⁢ k ⌉ ⁢ ⁢ mod ⁢ ⁢ 4 , where RV k is the redundanc version sequence, k=i mod 4, i=0,1, . . . ,n s w −1, and n s w denotes a number of subframes within the system information message transmission window.
