Patent ID: 8271017

Claim:
A method for controlling power of an uplink physical channel, comprising: generating a gain factor of an uplink Enhanced Dedicated Physical Data Channel (E-DPDCH) in a compressed mode by way of β ed , C , i = β c , C , j · A ed · L e , ref L e , I , i · K e , i K e , ref · 10 ( Δ harq 20 ) · 15 · N pilot , C N slots , I · N pilot , N if an Enhanced-Dedicated Channel (E-DCH) Transmission Time Interval (TTI) is 10 msec and a current frame is compressed, wherein the β ed,C,i is a gain factor of the E-DPDCH in the compressed mode, the β c,C,j is a gain factor of a Dedicated Physical Control Channel (DPCCH) in the compressed mode, the A ed is a relative gain factor of the E-DPDCH/DPCCH for a reference Enhanced-TFC (E-TFC) in a non-compressed mode, the L e,ref denotes the number of E-DPDCHs for the reference E-TFC, the L e,I,i denotes the number of E-DPDCHs used for i:th E-TFC in a first frame used for transmitting data, the K e,ref denotes a transport block size of the reference E-TFC, the K e,i denotes a transport block size of the current E-TFC, the Δ harq is a Hybrid Automatic Repeat Request (HARQ) offset, the N pilot,C is the number of pilot bits per slot on the DPCCH in compressed frames, the N pilot,N is the number of pilot bits per slot on the DPCCH in non-compressed frames, and the N slot,I is the number of non DTX slots in the first frame used for transmitting the data; and controlling power of the uplink physical channel according to the generated gain factor in the compressed mode.
