Patent ID: 8559376

Claim:
A non-transitory computer readable medium, comprising: a computer program code comprising one or more instructions, which, when executed by a computer device, cause the computer device to determine an Enhanced Dedicated Channel Dedicated Physical Data Channel (E-DPDCH) gain factor in compressed mode, according to the number of E-DPDCHs for an initial transmission of data, and cause the computer device to transmit a signal using the determined E-DPDCH gain factor, wherein, when a current frame is a compressed frame, the computer program code is configured to, when executed by the computer device, cause the computer device to determine the E-DPDCH gain factor in the compressed mode as follows: β ed , C , i = β c , C , j · L e , ref , 1 L e , I , i · ( ( L e , ref , 2 L e , ref , 1 ⁢ A ed , ref , 2 2 - A ed , ref , 1 2 K e , ref , 2 - K e , ref , 1 ) ⁢ ( K e , i - K e , ref , 1 ) + A ed , ref , 1 2 ) · 10 ( Δ ⁢ ⁢ harq 20 ) · 15 · N pilot , C N slots , I · N pilot , N wherein, β ed,C,i denotes the E-DPDCH gain factor in the compressed mode, L e,I,i denotes the number of the E-DPDCHs for the initial transmission of data, β c,C,j denotes a Dedicated Physical Control Channel (DPCCH) gain factor used for the j:th TFC in the compressed mode, A ed , ref , 1 = β ed , ref , 1 β c , and A ed , ref , 2 = β ed , ref , 2 β c , where β c is a DPCCH gain factor in non-compressed mode, β ed,ref,1 and β ed,ref,2 denote the E-DPDCH gain factors of a first and a second reference E-TFCs, respectively, L e,ref,1 and L e,ref,2 denote the number of the E-DPDCHs used for the first and second reference E-TFCs, respectively, K e,ref,1 and K e,ref,2 denote transport block sizes of the first and second reference E-TFCs, respectively, K e,i denotes the transport block size of the i:th E-TFC, Δ harq denotes an offset of a Hybrid Automatic Repeat Request (HARQ), N pilot,C denotes the number of pilot bits p er slot on a DPCCH in the compressed mode, N pilot,N denotes the number of pilot bits per slot on the DPCCH in the non-compressed mode, and N slots,I denotes the number of non Discontinuous Transmission (DTX) slots in a frame used for the initial transmission of data.
