Patent ID: 8885611

Claim:
An apparatus comprising: at least one data processor; and at least one memory including computer program code, where the at least one memory and computer program code are configured, with the at least one data processor, to cause the apparatus at least to determine a fine tuning factor usable by at least one other apparatus operative in a wireless communications network to determine, in conjunction with a reference gain factor, a gain factor that relates a data signal transmitted by the at least one other apparatus in a data channel and a control signal transmitted by the at least one other apparatus in a control channel, the fine tuning factor being a factor used in a formula in conjunction with the reference gain factor to calculate the gain factor, where the usage of the fine tuning factor is data rate dependent; and to transmit the fine tuning factor to the at least one other apparatus; where the formula can be expressed as: β ed , i , harq = β ed , ref ⁢ L e , ref L e , i ⁢ ( K e , i K e , ref ) Factor · 10 ( Δ ⁢ ⁢ harq 20 ) , where β ed,ref denotes the reference gain factor of a reference (ref) enhanced transport combination (E-TFC), L e,ref denotes a number of enhanced dedicated physical control channels (E-DPDCHs) used for the reference E-TFC, L e,i denotes the number of E-DPDCHs used for an i:th E-TFC, K e,ref denotes a transport block size of the reference E-TFC, K e,i denotes the transport block size of the i:th E-TFC, Δharq is a hybrid automatic repeat request (HARQ) offset and Factor is the fine tuning factor.
