In a system with a system bandwidth of 1.4 MHz, as shown in Figure 1. Cell-specific Reference Signals (CRS) are transmitted in all downlink sub-frames supporting Physical Downlink Shared Channel (PDSCH M). The system can support single-antenna port transmission (P0) and two antennas. Port transmission (P0, P1) or four antenna port transmission (P0, PI, P2, P3), as shown in Figure 2.
为了降低系统开销， LTE Rel-11中讨论定义 NCT载波， 该 NCT载波中不传输传统的 PDCCH, 即图 1 所示的 PDCCH。 该 NCT 载波内基于用户专属参考信号 （UE-specific Reference Signals , URS )进行数据解调， URS结构如图 3所示。 CRS不传输或每 5ms占 用一个子帧传输且只传输 P0  In order to reduce the system overhead, the NCT carrier is defined in LTE Rel-11, and the traditional PDCCH is not transmitted in the NCT carrier, that is, the PDCCH shown in FIG. The NCT carrier performs data demodulation based on UE-specific Reference Signals (URS). The URS structure is shown in Figure 3. CRS does not transmit or takes one subframe transmission every 5ms and only transmits P0
非 NCT载波上的传输块大小 （Transport Block Size, TBS ) 的确定方法如下： 终端根据接收基站发送的信令获取传输当前 PDSCH所使用的调制编码等级信息 /MCS 和分配的物理资源块 ( Physical Resource Block, PRB ) 大小
Figure imgf000002_0001
The method for determining the transport block size (TBS) on the non-NCT carrier is as follows: The terminal acquires modulation coding level information/ MCS used for transmitting the current PDSCH and the allocated physical resource block according to the signaling sent by the receiving base station (Physical Resource) Block, PRB ) size

LTE系统中数据信道釆用 Turbo编码， 为提高编译码速度， 系统限定一个编码块的最 大长度为 6144比特。 若传输块添加 24比特的循环冗余校验位 ( Cyclic Redundancy Check, CRC )后的长度大于 6144, 则需要对传输块进行码块分割得到多个长度较小的码块， 其中 每个码块的长度 k Κ, K如表 6所示。 然后对较小的码块分别进行 Turbo编码。

In the LTE system, the data channel is turbo encoded. To improve the encoding and decoding speed, the system defines a coding block with a maximum length of 6144 bits. If the length of the transport block is greater than 6144 after adding a Cyclic Redundancy Check (CRC), the code block needs to be coded to obtain a plurality of code blocks with smaller lengths, where each code block is used. The length k Κ, K is shown in Table 6. Turbo coding is then performed on the smaller code blocks.

综上， 在 NCT载波中不传输 PDCCH, 不传输或少量传输 CRS, 系统开销较低。 若在 NCT上釆用与非 NCT载波相同的方法确定 TBS,则得到的 TBS将会低于实际需要的 TBS, 造成资源浪费。  In summary, the PDCCH is not transmitted in the NCT carrier, and the CRS is not transmitted or transmitted in a small amount, and the system overhead is low. If the TBS is determined on the NCT in the same way as the non-NCT carrier, the obtained TBS will be lower than the actual required TBS, resulting in waste of resources.
