This operation mode is also used for pre-emption and access control algorithms,

defining the available resources for CSG and non-CSG users in terms of resource

(blocks, bearers).

Channel and bearer support

The following essential LTE channel and bearer features relevant for the Apex

Lifestyle Small Cell are supported:

• Fixed OFDM symbols used for PDCCH (1-2-3 OFDM symbols)

• CCE aggregation for PDCCH (1, 2, 4, and 8 CCEs)

• DCI formats 0, 1, 1A, 2, 2A, 3, 3A

• PDSCH resource allocation types 0 and 2

• RACH Optimization allows:

— Maximize the Random Access probability through the RACH channel

— Minimize interference to the neighbor cells

— Consider handover performance to/from the neighbor cells

• RACH configuration is done autonomously according to pre-defined operator

rules and parameter ranges. dSON is used for monitoring and tuning applicable

configuration parameters. Cells monitor their RF environemt to:

— Minimize control PRACH channel collision

— Maximize Random Access performance

— Support successful and failed configuration (ALARM!)

• Contention-based operation of the random access procedures

• Independent power settings for all downlink physical channels and signals

(includes downlink power boosting for PDCCH)

• Establishment, maintenance and release of physical radio bearers

• Support of default and dedicated EPS bearers

• GBR Bearer support

• Non-GBR Bearer support

• Up to 8 EPS bearers per UE (incl. combination of GBR and Non-GBR)
