A continuous signal, or waveform, at a certain frequency on a circuit, or within a certain frequency range, and that can be modulated to support an information-bearing signal.
The technology used for the radio transmission between base station and mobile units in a wireless network.
A digital transmission technique that uses a large number of carriers spaced apart at slightly different frequencies.
The ratio of the number of erroneous blocks received to the total number of blocks sent. An erroneous block is defined as a Transport Block, the cyclic redundancy check (CRC) of which is wrong.
A collaboration that unites six telecommunications standard development organizations (ARIB, ATIS, CCSA, ETSI, TTA, TTC), known as "Organizational Partners" and provides their members with a stable environment to produce the highly successful Reports and Specifications that define 3GPP ...
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 duplex (FDD), with the forward and backward time division multiplexed (TDM) channels riding over ...
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 which resource blocks are assigned to which user. The number of parallel resource blocks in each ...
