TL;DR: In this article, a method and apparatus for controlling Discontinuous Reception (DRX) by a user equipment (UE) in a wireless communication system is provided, in which the UE receives a DRX configuration parameter from an evolved Node B (eNB), and determines whether to start an on-duration timer based on the configuration parameter, after a change in DRX cycle is completed in a subframe, thereby preventing system performance degradation caused by transmission mismatch between the eNB and the UE.

TL;DR: In this article, an intercell interference coordination method and apparatus is provided for mitigating inter-cell interference in a wireless communication system by using interference coordination information exchanged among neighbor base stations, where each message including interference indicators of resource blocks, allocating the resource blocks with transmission power per resource block to user equipments served by the base station based on the power control and interference coordination messages, generating outgoing interference coordination message for the respective neighbor BSs.

TL;DR: A mobility load balancing algorithm for small-cell networks is proposed by adapting network load status and considering load estimation, which provides a more balanced load across networks and higher network throughput than previous algorithms.

TL;DR: Simulation results with MER show that accounting for location errors significantly improves the performance of geographic routing, and it is shown that in a mobile environment MER performs better than existing approaches.

TL;DR: This paper develops an energy efficient routing scheme that takes into account the interference created by existing flows in the network, and shows that the routes chosen are more energy efficient than the state of the art.
