Patent ID: 8385966

Claim:
A method comprising: using a processor to initialize for i=0 a first power control adjustment state g(i) for an uplink control channel and a second power control adjustment state f(i) for an uplink shared channel to each reflect an open loop power control error; using the processor to compute an initial transmit power for the uplink shared channel using full path loss compensation, wherein the initial transmit power depends on a preamble power of a first message sent on an access channel and the second power control adjustment state f(0); and sending from a transmitter a third message on the uplink shared channel at the initial transmit power; wherein the second power control adjustment state f(i) for i=0 is initialized as: P 0 — UE — PUSCH +f (0)=Δ P PC +ΔP rampup ; in which: P 0 — UE — PUSCH is a power control constant for the uplink shared channel that is specific for a user equipment executing the method; ΔP rampup is a ramp-up power for preamble transmissions; and ΔP PC is a power control command indicated in a second message that is received in response to sending the first message.
