LTE Channel Mapping and UE Categories LTE (Long-Term Evolution) is a wireless communication standard that provides high-speed data transmission for mobile devices. LTE utilizes various channels for communication between the User Equipment (UE), such as smartphones or tablets, and the LTE base station, known as the eNodeB (evolved NodeB). The channel mapping in LTE defines … Read more
The 3G Iub interface is the terrestrial interface between NodeB and RNC. The Radio Network Layer defines procedures related to the operation of the WCDMA NodeB. The Transport Network Layer defines procedures for establishing physical connections between the 3G NodeB and the 3G RNC. The 3G Iub application protocol, WCDMA NodeB application part (NBAP) initiates … Read more
Here I write about a simulation analysis of the system performance deterioration caused by the following four types of interference: eNodeB->UE, UE->eNodeB, eNodeB->eNodeB, and UE->UE when two systems share the eNodeBs. During simulation, it is assumed that the time percentage of the interference occurrence is 100%, that is, interference is always there. From simulation result … Read more
