Uplink CE consumption is more than that of downlink. The reason is that CEs are not utilized by HSDPA being a shared channel. HSUPA and R99, on the other hand, consume dedicated CS resources for their respective sessions.

Sector Swap (Cross-sector) Issue
Sector-Swap Issue means that sector of a site is serving the area in a direction different to its azimuth. For instance, sector 1 is serving the area of sector 2 and sector 2 is serving the area of sector 1. This is known as complete Sector Swap. Another type is Partial Swap in which the logical area of say sector 1 is served partially by sector 2 and partially by sector 1 itself.
This problem arises due to jumbled cables at the BTS which could be caused due to human mistake during site maintenance activities. Issue can be diagonosed through Drive Test results as well as observing the number of Handover requests in Handover statistics of the site.
The issue can cause increase in CDR, RxQual degradation, increased DL interference,
Resolution can be done by closely following the cables from the antenna to the respective TRX of each sector of the BTS and correcting the cross-connections.
