English (EN)A transmission method that uses the same channel for the uplink and downlink (transmit and receive), but separates them by time slots. TDD typically is used in conjunction with frequency-division ...
A single transmission step with a length of 66.667 microseconds. Several bits can be transmitted per symbol depending on the modulation scheme.
Two consecutive time slots, each of 0.5 ms duration. A subframe represents the LTE scheduling time, which means that at each millisecond the eNode-B decides as to which users are to be scheduled and ...
A frequency channel that occupies only a portion of RF bandwidth allocated to the carrier and, therefore, has a smaller information capacity. The more the bandwidth available for the overall LTE ...
A combination of 10 subframes with a length of 10 milliseconds. Frames are important for the scheduling of periodic system information.
The base station of the LTE network. The eNodeBs are normally interconnected with each other by means of an interface known as "X2" and to the EPC by means of the S1 interface, more specifically, to ...
A power efficient transmission scheme for uplink LTE. A major advantage of SC-FDMA over the Direct-Sequence Code Division Multiple Access (DS-CDMA) scheme used in UMTS is that it achieves intra-cell ...
