example 1
[0092] In the implementation, the transmission time slots of each downlink physical channel and corresponding uplink physical channel are shown in the above table, assuming that the uplink accompanying DPCH of subframe n+i1 carries the PC command word response of the downlink accompanying DPCH of subframe n, subframe n+i1 The E-PUCH of i3 carries the PC command word response of the E-AGCH of subframe n+i2; the reference transmission power of subframe n is refer_p_tx(n), and the update time of refer_p_tx is subframe n.
[0093] The transmit power of subframe n downlink accompanying DPCH is refer_p_tx(n) plus the power offset of DPCH;
[0094] Subframe n+i2 first updates refer_p_tx according to the PC on the DPCH of n+i1 subframe, and the update time of refer_p_tx is subframe n+i1:
[0095] refer_p_tx(n+i1)=refer_p_tx(n)+DPCH_PC(n+i1)
[0096] Then the transmission power of the E-AGCH is refer_p_tx(n+i1) plus the power offset of the E-AGCH.
example 2
[0099] In the implementation, the transmission time slots of each downlink physical channel and corresponding uplink physical channel are shown in the above table, assuming that the uplink accompanying DPCH of subframe n+i3 carries the PC command word response of the downlink accompanying DPCH of subframe n, subframe n+i3 The E-PUCH of i2 carries the PC command word response of the E-AGCH of subframe n+i1; the unified transmission power of subframe n is refer_p_tx(n), and the update time of refer_p_tx is subframe n.
[0100] When the E-AGCH is sent in the n+i1 subframe, it is judged according to the rules that refer_p_tx does not need to be updated, and the transmission power of the E-AGCH is refer_p_tx(n) plus the power offset of the E-AGCH.
[0101] Before sending data in subframe n+i4, it is judged according to the rules that the PC using E-PUCH in subframe n+i2 updates refer_p_tx, and the update time of refer_p_tx is subframe n+i4:
[0102] refer_p_tx(n+i4)=refer_p_...
