Carrier Aggregation support for the LTE module
Student: Danilo Abrignani
Mentors: Marco Miozzo Nicola Baldo
- Abstract: 3GPP standardizes, in release R10, the Carrier Aggregation (CA) technology. This consists of the possibility, for a single user equipment (UE), to aggregate Radio Resources belonging to different carriers, in order to have more bandwidth available, and a higher potential throughput. The idea is to improve the current LENA implementation, with CA functionalities, by implementing a sort of “proxy” between the RLC/RRC layer and MAC/Scheduler layers, associated to the multiple carriers.

- About me: I'm a Ph.D. candidate at the University of Bologna, Italy. My research interests are in wireless sensor network and mobile network simulation. Something more about me on my Linkedin page.
Plan
- 1st Week:
* Implementation of RRC messages for Carrier Aggregation support * Writing design documentation
- 2nd - 4th Weeks:
* Implementation of the LTE-A helper, activation of different carriers and synchronization procedure. * Writing test code and debugging. * Writing design documentation

* Write test documentation, submit code for review, consolidate code and documentation.
- 7th -8th Weeks:
* Start writing the CA-Mac module, design documentation. * Write test and debugging, writing test documentation, submit code for review.
- 9th - 10th Weeks:"'
* Define a basic algorithm that takes into account QoS indicators. Write design documentation * Writing test application and debugging. Submit code for review. Update code and documentation.
- 11th - 12th Weeks:
* Unified LTE-A and LTE helpers. * Write test applications, update documentation and code. * Possible improvements.
Weekly Progress
Week 1 (May 25, 2015 - May 31, 2015)
First week of coding phase has delivered the following:
- Implementation of RRC messages for Carrier Aggregation support
- Implementation of CcsAlgorithm abstract class which will be base class for Carrier Component Selection (CCS) algorithms
- Implementation of SAPs
- LteHelper was updated to install CCS entity and SAPs during setting up EnbNetDevice. However, currently no ccs algorithm is implementing.
