获取每个子帧中TDD（配置0）帧中的下行链路OFDM符号的数量。

A Configuration 0 TDD frame is organized as follows:

  • Only subframes 0, 1, 5, and 6 will contain a non-zero number of DL OFDM symbols.

  • Subframe 0 and 5 are designated for DL.

  • 子架1和6是特殊的子框架。

  • Subframes 2, 3, 4, 7, 8, and 9 are designated for UL.

Initialize a cell-wide configuration structure for RMC R.0 and a Configuration 0 TDD frame.

enb = lteRMCDL('r.0'）；enb.duplexmode ='TDD'; enb.SSC = 0; enb.TDDConfig = 0;

Loop through all subframes in a frame.

forn = 0:9 enb.NSubframe = n; duplexInfo = lteDuplexingInfo(enb); fprintf('DL symbols in subframe %d: %d\n',n,duplexInfo.NSymbolsDL)end

Duplex Mode Configuration

For FDD duplex mode:

  • IfCyclicPrefixULis present, the link direction is assumed to be uplink.

  • IfCyclicPrefixUL不存在，假定链路方向是下行链路，并且循环前缀是根据CyclicPrefix.

    • IfCyclicPrefixis also not present, the default'Normal'cyclic prefix is used.

对于TDD双工模式：

  • The subframe type can beuplink,downlink, orspecial.TDDConfig和NSubframeidentify the subframe type as specified in TS 36.211[1], Table 4.2-2.

    • For uplink or downlink subframes,CyclicPrefixUL或者CyclicPrefix, respectively, indicate the relevant cyclic prefix setting.

    • For special subframes, thelteDuplexingInfo功能用途SSC和CyclicPrefixto identify the special subframe configuration, as specified in TS 36.211[1], Table 4.2-1.
