Carrier aggregation explained 3gpp. 4.1 proposed phrpera scheme. In the 3gpp ltea uplink, one of the parameters that determines the ue transmission power is the number of prbs for data transmission. As discussed above, allocating more prbs than the ue power can afford will reduce the power per prb owing to the ue transmission power constraint, causing power inefficiency. Lteadvanced.

Sharetechnote. Phr is a type of mac ce(mac control element) that report the headroom between the current ue tx power (estimated power) and the nominal power. Enodeb (network) use this report value to estimate how much uplink bandwidth a ue can use for a specific subframe. Since the more resource block the ue is using, the higher ue tx power gets,

What are main reasons of low throughout in 4g lte? Lte. Lte throughput optimization part 2 spectral efficiency. It is proportional to throughput as the throughput is also bits per time transmitted in a certain bandwidth. From lte’s perspective, if the number of bits transmitted in a subframe (time) over a specific number of resource blocks (frequency bandwidth) is high, 4g lte testing & certification intertek.
