WHAT AVAILABLE LOGICAL CHANNELS EXIST IN LTE ?
Logical channels carry the type of information. In this regard, logical channels can be divided into control channels and traffic channels. The control channels are used for transfer of control plane information and the traffic channels are used for the transfer of user plane information. The logical channels in LTE Air Interface are shown in […]

WHAT IS LINK ADAPTION?
Link Adaptation is about improving modulation and coding scheme (MCS) to reach users in a better way in terms of throughput and data rate, wherever they are standing within the cell coverage. Even if they are standing closer to the cell edge or farther from the cell, eNodeB scheduler will adjust its modulation scheme and/or […]

What are the agreed state transitions between 2G/3G and LTE?
The agreed state transitions that will be supported between 2G/3G and LTE are shown in Figure below. The methods to execute the supported state transitions are the following: A) = PDP Context establishment needed, if no PDP context exists. Network controlled, prepared handover, for UEs in connected state Network controlled Cell Change Order (CCO) with […]
