Performance Management Statistics have recently shown a sharp rise in received interference power on an LTE site during the busiest hours. A collocated WCDMA base station has recently acquired a new carrier and upgraded power amplifier. The upgrade correlates with the sharp rise in received interference

power.

What are two appropriate actions to solve this problem? (Choose two.)

A.

Request or perform a build audit of the newly upgraded collocated WCDMA site.

B.

Increase the power amplifier on the impacted collocated LTE sectors.

C.

Reduce the hsPowerMargin parameter to make more power available for HSDPA.

D.

Review the site design in consultation with the Ericsson collocation and coexistence guidelines.
