LTE: AN OVERVIEWBASIC TRANSMISSION SCHEMEOrthogonal frequency-division multiplexing, with data transmitted on a large number of parallel, narrow-band subcarriers, is the core of the LTE downlink radio transmission. Due to the use of relatively narrowband subcarriers in combination with a cyclic prefix, OFDM transmission is inherently robust to time dispersion on the radio channel without a requirement to resort to advanced and potentially complex receiver-side channel equalization. For the downlink, this is an attractive property because it simplifies the receiver baseband processing with reduced terminal cost and power consumption as consequences. This is especially important considering the wide transmission bandwidths of LTE,and even more so in combination with advanced multi-antenna transmission, such as spatial multiplexing (discussed below in this section).For the uplink, where the available transmission power is significantly lower than for the downlink, the situation is somewhat different. Rather than the amount of processing power at the receiver, one of the most important factors in the uplink design is to enable highly power-efficient transmission. This improves coverage and reduces terminal cost and power consumption at the transmitter. For this reason, single-carrier transmission, based on discrete Fourier transform (DFT)-precoded OFDM, sometimes also referred to as single carrier frequency-division multiple access, is used for the LTE uplink. DFT precoded OFDM has a smaller peak-to-average power ratio than regular OFDM, thus enabling less complex and/or higher-power terminals.The basic protocol structure of LTE is illustrated in Fig. 1. The radio link control (RLC) and medium access control (MAC) layers, among other tasks, are responsible for retransmission handling and multiplexing of data flows. In the physical layer, the data that is to be transmitted is turbo coded and modulated using one of the following: quadrature-phase shift keying (QPSK),16-QAM, or 64-QAM, followed by OFDM modulation. The subcarrier spacing is 15 kHz and two cyclic-prefix lengths are supported in both uplink and downlink, a normal cyclic prefix of 4.7 µs, suitable for most deployments and an extended cyclic prefix of 16.7 µs for highly dispersive environments. In the downlink, different types of multi-antenna processing, further described below, are applied prior to OFDM modulation. In the uplink, to preserve the single-carrier properties, a DFT precoder is used prior to the OFDM modulator. Note that the DFT precoder does not compromis orthogonality between subcarriers. To support channel estimation for coherent demodulation, as well as for various measurement purposes, including not only measurements for mobility management but also channel quality measurements, cell-specific reference signals are transmitted in the downlink.The transmitted signal is organized into subframes of 1-ms duration, each consisting of 14 or 12 OFDM symbols, depending on whether normal or extended cyclic prefix is used. Ten subframes form a radio frame as shown in Fig. 2. The short subframe duration of 1 ms results in small delays,not only for user data, but also for control signaling such as the hybrid automatic repeat-reQuest (ARQ) feedback and channel-quality feedback from the terminals to the base station.As illustrated in Fig. 2, LTE supports FDD,as well as TDD, the latter commonly referred to as TD-LTE. Although the time-domain structure is, in most respects, the same for both duplexing schemes, there are some differences between the two, most notably the presence of a special subframe in TD-LTE to provide the required guard time for downlink-to-uplink switching as further elaborated below.An intrinsic characteristic of radio communication is fading, which results in the instantaneous radio-channel quality varying in time, space, and frequency. Due to the use of OFDM based transmission, LTE can use channel-dependent scheduling in both the time and frequency domain to exploit rather than suppress such rapid channel-quality variations, thereby achieving more efficient utilization of the available radio resources. This is illustrated in Fig. 3. The scheduler determines, for each 1 ms subframe, which users(s) are allowed to transmit, on what frequency resources the transmission is to take place, and what data rate to use. The short subframe duration of 1 ms allows relatively fast channel variations to be tracked and utilized by the scheduler. In the frequency domain, the scheduling granularity is 180 kHz. Note that both the downlink and uplink transmissions are controlled by the scheduler located in the base station. The scheduler is thus a key element and to a large extent determines the overall downlink system performance, especially in a highly loaded network. To aid the downlink scheduler in its decision, the instantaneous channel-quality at the terminals is estimated and fed back to the base station, possibly as often as once per subframe. In the uplink, the terminals can be configured to transmit a sounding reference signal, the reception quality of which may be used for uplink channel-dependent scheduling.To handle occasional retransmission errors,LTE includes a two-layered retransmission scheme: a fast hybrid-ARQ protocol with low overhead feedback and support for soft combining with incremental redundancy is complemented by a highly reliable selective-repeat ARQ protocol. This can be seen in Fig. 1 with hybridARQ located in the MAC layer and ARQ in the RLC layer. The use of a two-layered mechanism achieves low latency and low overhead without sacrificing reliability. Most errors are captured and corrected by the lightweight hybrid-ARQ protocol, which provides feedback to the transmitter for each transmitted subframe; only rarely, in terms of latency and overhead, the more expensive ARQ retransmissions are required. The tight coupling between the two retransmission layers is possible because both mechanisms are terminated in the base station.To support the LTE features, scheduling decisions, hybrid-ARQ feedback, channel-status reports, and other control information must be communicated between the base station and the terminal. In the downlink, the control signaling is transmitted using (typically) up to three of the first OFDM symbols in each subframe. The code rate of the control signaling for each terminal can be adjusted individually to match the instantaneous channel conditions and to minimize the overhead. Also, the total amount of resources in the downlink used for control signaling can be varied dynamically to minimize the overhead.。
