Backoff Algorithms in LTE Random Access

This paper analyzed several common Random Access technologies, described in detail the functions, classification and process of Random Access in LTE, focused on the research of Preamble management and Backoff algorithms in LTE Random Access procedure.

In the research of Preamble management, the different proposals about Preamble management schemes are discussed, and a based resource sharing Preamble management scheme is proposed. This scheme combines the advantages of both dynamic management and static management, which reduces the cost of system information about the Preamble allocation, due to broader scope of its application. Keep your cheap nike shoes close!And the performance on access success ratio of this scheme is verified through mathematical analysis and simulation. In the research of Backoff algorithms, analyzed several common Backoff algorithms, compared their performance on delay and throughput rate through simulation, based on the discussion on the application form of the Backoff algorithm in the LTE, found the Rivest's pseudo-Bayesian algorithm is suitable for application in LTE system. Cheap Nike shoes are very nice here! Rivest's pseudo-Bayesian algorithm is applied to the based resource sharing Preamble management scheme and its performance on delay and throughput rate is analyzed through simulation.
