Uplink power controlWhat's behind?

sufficient Ebit /N0 to

achieve required QoS

uplink interference,

maximize battery life

l Characteristic of radio channel with multipath propagation (path loss,

shadowing, fast fading) as well as the interference “provided” through other users – both within the same cell and from neighboring cells – needs to be

Some comments on UL power control in LTE…or in other words what is different to 3G (UTRA FDD = WCDMA)?

l SC-FDMA is the UL transmission scheme, so transmission of

different UE’s in the same radio cell is (almost) orthogonal by

nature, means intra-cell interference is less critical than in WCDMA, – n ata rate s ncrease y ower ng t e sprea ng actor ncreas ng t e

transmission power increase of intra-cell interference,

– In LTE data rate is increased by varying the allocated bandwidth and the

Modulation Coding Scheme (MCS), where the power can remain typically the same

, …,

l WCDMA uses periodic power control (0.667ms) normally with a

step size of ±1 dB (“fast power control”), where LTE allows larger

power steps, ut not necessar y per o ca y,

– LTE uses a combination of open-loop and close-loop for UL power control, as this

is more affordable and requires less feedback (signaling overhead) than WCDMA, – Open-loop is used to set a coarse operating point, where close-loop will be used for
