## eNB PHY Layer ##
The Physical layer implements **3GPP 36.211**, **36.212**, **36.213** and provides the following features:
- LTE release 8.6 compliant, and implements a subset of release 10
- FDD and TDD configurations: 1 (experimental) and 3
- Bandwidth: 5, 10, and 20 MHz
- Transmission modes: 1, 2 (stable), 3, 4, 5, 6, 7 (experimental)
- Max number of antennas: 2
- CQI/PMI reporting: aperiodic, feedback mode 3 - 0 and 3 - 1
- PRACH preamble format 0
- All downlink (DL) channels are supported: PSS, SSS, PBCH, PCFICH, PHICH, PDCCH, PDSCH, PMCH
- All uplink (UL) channels are supported: PRACH, PUSCH, PUCCH (format 1/1a/1b), SRS, DRS
- HARQ support (UL and DL)
- Highly optimized base band processing (including turbo decoder)

## eNB MAC Layer ##
The MAC layer implements a subset of the **3GPP 36.321** release v8.6 in support of BCH, DLSCH, RACH, and ULSCH channels.
- RRC interface for CCCH, DCCH, and DTCH
- Proportional fair scheduler (round robin scheduler soon)
- DCI generation
- HARQ Support
- RA procedures and RNTI management
- RLC interface (AM, UM)
- UL power control
- Link adaptation
## eNB RLC Layer ##
The RLC layer implements a full specification of the 3GPP 36.322 release v9.3.
- RLC TM (mainly used for BCCH and CCCH)
* Neither segment nor concatenate RLC SDUs
* Do not include a RLC header in the RLC PDU
* Delivery of received RLC PDUs to upper layers
- RLC UM (mainly used for DTCH)
* Segment or concatenate RLC SDUs according to the TB size selected by MAC
* Include a RLC header in the RLC PDU
* Duplication detection
* PDU reordering and reassembly
- RLC AM, compatible with 9.3
* Segmentation, re-segmentation, concatenation, and reassembly
* Padding
* Data transfer to the user
* RLC PDU retransmission in support of error control and correction
* Generation of data/control PDUs
## eNB PDCP Layer ##
The current PDCP layer is header compliant with **3GPP 36.323** Rel 10.1.0 and implements the following functions:
- User and control data transfer
- Sequence number management
- RB association with PDCP entity
- PDCP entity association with one or two RLC entities
- Integrity check and encryption using the AES and Snow3G algorithms
## eNB RRC Layer ##
The RRC layer is based on **3GPP 36.331** v14.3.0 and implements the following functions:
- System Information broadcast (SIB 1, 2, 3, and 13)
- RRC connection establishment
- RRC connection reconfiguration (addition and removal of radio bearers, connection release)
- RRC connection release
- RRC connection re-establishment
- Inter-frequency measurement collection and reporting (experimental)
- eMBMS for multicast and broadcast (experimental)
- Handover (experimental)
- Paging (soon)
