- LTE-A can provide spectrum bandwidth of up to 100MHz, supporting more flexible and higher quality communication
- LTE-A system has good after To compatibility.
- the LTE-A system there are multiple component carriers (CCs), one LTE terminal can only work on one backward compatible CC, and the stronger LTE-A terminal can simultaneously in multiple CCs. Transfer on. That is, the terminal implementing the LTE-A simultaneously transmits and receives data in a plurality of component carriers, thereby achieving the purpose of increasing the bandwidth.
- This technique is known as multi-carrier aggregation technology.
- NCT new carrier type
- LTE R11 LTE Release 11
- the definition of a new carrier in LTE R11 is that it needs to be paired with at least one compatible carrier (also referred to as carrier-aggregation operation with a compatible carrier), and the cell-specific reference signal of LTE R8 is not configured in the new carrier ( Cell-specific Reference Signals (CRS) to avoid neighboring cells at the cell edge Severe CRS interference, especially in the heterogeneous network (HETerogeneous NETwork, HetNet) scenario, CRS interference between macro cells and micro cells.
- CRS Cell-specific Reference Signals
- a new carrier that operates independently is also proposed.
- the new carrier has the capability of independently accessing User Equipment (UE) and operating independently.
- UE User Equipment
- it can also be paired or aggregated with other carriers.
- the new carrier is being standardized as a new carrier type.

- 5msCRS synchronization tracking
- the number of ports is different.
- the new carriers especially the synchronous new carrier, it is currently discussing whether to configure the Primary Synchronization Signal/Secondary Synchronization Signal (PSS/SSS) and 5msCRS. If the result of the discussion is not to configure PSS/SSS and The 5ms CRS, the physical downlink control channel (PDCCH) field is not configured in the new carrier, and the original PDCCH domain may be used to transmit the Physical Downlink Shared Channel (PDSCH).
