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 carrier, the more the number of subcarriers used.To save bandwidth, the subcarriers are spaced in such a ...
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 the MME by means of the S1-MME interface and to the S-GW by means of the S1-U interface.
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 orthogonality even in frequency-selective channels. SC-FDMA avoids the high level of intra-cell ...
The node responsible for managing user data tunnels between the eNode-Bs in the radio network and the Packet Data Network Gateway (PDN-GW).
A sublayer of radio interface Layer 3 existing in the control plane only which provides information transfer service to the non-access stratum.
A protocol that handles segmentation and windowing of packets. Proper RLC parametrisation may reduce the probability of (end-to-end) TCP retransmissions, which are slow and are known to have a dramatic impact on TCP flow management and network loading.
A set of 7 consecutive OFDM symbols in the time domain and 12 consecutive subcarriers in the frequency domain. A physical resource block contains 84 Resource Elements and represents one slot in the time domain of 180 kHz in the frequency domain.
