说实话,在你提之前,我还真没有了解过TM10。当然,网上有介绍TM10的,https://www.rohde-schwarz.com/applications/lte-transmission-modes-and-beamforming-application-note_56280-15744.html,其中写道 Release 11 adds Transmission Mode 10. This mode is similar to TM9 (see 3.2.9). Again, up to eight layers can be used, so up to eight physical transmit antennas are needed, this leads to up to 8x8 MIMO configurations. The number of used layers may be defined dynamically. The virtual antenna ports 7…14 are used. TM10 uses the same reference signals like TM9 The main difference to TM9 is the used DCI format (2D). With TM10 Coordinated Multi Point Transmission (CoMP, see [10]) is supported. CoMP uses in principle the same MIMO technique like TM9, but the transmit antennas may be physically on different base station sites. DCI format 2D allows to tell the UE, that it can assume a quasi co-location of the antenna ports with respect to Doppler shift, Doppler spread, average delay, and delay spread. |
