In case of multi-antenna transmis

43、sion, the modulation symbols are mapped to multiple layers and precoded before being mapped to the different antenna ports. Alternatively, transmit diversity can be applied. Finally, the (precoded) modulation symbols are mapped to the time-frequency resources allocated for the transmission. Downlink

44、 transmission is based on conventional OFDM with a cyclic prefix. The subcarrier spacing is f = 15 kHz and two cyclic prefix lengths are supported: normal cyclic prefix 4.7 s and extended cyclic prefix 16.7 s. In the frequency domain, the number of resource blocks can range from 6 to 110 per compone

45、nt carrier (for channel bandwidths ranging from 1.4 to 20 MHz respectively), where a resource block is 180 kHz in the frequency domain. There can be up to five component carriers transmitted in parallel implying an overall bandwidth up to 100 MHz. Uplink transmission is based on DFT-spread OFDM (DFT

46、S-OFDM). DFTS-OFDM can be seen as a DFT precoder, followed by conventional OFDM with the same numerology as in the downlink. Multiple DFT precoding sizes, corresponding to transmission with different scheduled bandwidths, can be used. Depending on the deployed satellite/UE power amplifier performanc

47、e, DFTS-OFDM and Offset-modulated Single-Carrier (OSC) could be used in both uplink and downlink of UE-Satellite link. The remaining downlink transport channels (PCH, BCH, MCH) are based on the same general physical-layer processing as DL-SCH, although with some restrictions in the set of features u

Open-loop spatial multiplexing, also known as large-delay cyclic delay diversity, of up to four layers using cell-specific reference signals. Spatial multiplexing of up to eight layers using UE-specific reference signals. CGC may use feedback reports or exploit channel reciprocity to set the beam-forming weights.
