Problem to be solved: to provide a method for indicating a modulation coding method (MCS) to a user device (UE) in LTE. The UE receives downlink control information (DCI) including the uplink grant of the resource from the development node B (ENB).The DCI is configured to convey an ...
(36.213) Modulation order determination The UE shall use and Table 7.1.7.1-1 to determine the modulation order ( ) used in the physical downlink shared channel. Table 7.1.7.1-1: Modulation and TBS index table for PDSCH MCS Index Modulation Order TBS Index 0 2 0 1 2 1 2 2 2 3 2 3 ...
[itbs,mod,rv]=lteMCS()returns the physical downlink shared channel (PDSCH) MCS information for all MCS index values specified in Table 7.1.7.1-1 of[1]. The function returns the columns of the indexed MCS table entries as separate outputs. Theitbsoutput is a vector of the corresponding tran...
Syntax [itbs,mod,rv]=lteMCS() [itbs,mod,rv]=lteMCS(imcs) [itbs,mod,rv]= lteMCS(table) [itbs,mod,rv]=lteMCS(imcs,table)Description Use lteMCS to look up the modulation and coding scheme (MCS) information as defined by MCS index mapping to modulation and TBS index tables in TS ...

Now how much bits are transferred in this 1ms transport block size? It depends on the MCS (modulation and coding scheme) and the number of resource blocks assigned to the UE. We have to refer to the Table 7.1.7.1-1 and Table 7.1.7.2.1-1 from 3GPP 36.213 Lets assume that eNB assign...
This page mentions 5G NR MCS Table and 5G NR TBS Table as defined in 3GPP TS 38.214. MCS stands for Modulation and Coding Scheme and TBS stands for Transport Block Size. Introduction: 5G NR (New radio) is latest cellular wireless technology which follows 3GPP specifications similar to LTE. ...
LTE-下行MCS/NPRB的调度和分配 。比如: 1) UE上报的CQI为 7;2) CQI 7 对应的modulation为16QAM; (参考:TS36.213Table7.2.3中)3)16QAM对应Qm为4;4)Qm为... index查表得到NPRB;(参考:TS36.213Table7.1.7.2.1). 上接步骤4中的例子:5) 假如计算出的MCSindex 为16;6) 查表得到TBS index 为 ...
也就是说SR的优先级高于CQI。 CQI与SINR UE判决CQI的主要参数就是SINR,但是他们的映射关系不是绝对的,不同厂商是有略微差别,这个映射table一般是不对外公开的。 CQI可是看成是下行SINR的一种测量,但是不仅仅是SNR。CQI同时需要考虑SNR和UE的接收能力。
As can be seen in FIG. 1, the LTE architecture supports interconnection of different radio access networks (RAN) such as UTRAN or GERAN (GSM EDGE Radio Access Network), which are connected to the EPC via the Serving GPRS Support Node (SGSN). In a 3GPP mobile network, the mobile terminal...
