1【测试目的】
DTCH or DCCH mapped to UL SCH/ DL-SCH / Reserved Logical Channel ID
主要测试的是DTCH映射到UL-SCH, DL-SCH 和保留LCID的功能.
2【测试条件】
LTE Rel8 and UEs supporting E-UTRA

7.1.1.2 DTCH or DCCH mapped to UL SCH/ DL-SCH / Reserved Logical Channel ID
7.1.1.2.1 Test Purpose (TP)
(1)
with { UE in E-UTRA RRC_Connected state with DRB [Logical channel ID 3] established }
ensure that {
when { UE receives a MAC PDU on DL SCH and addressed to its CRNTI but including a reserved value for LCID }
then { UE shall not forward the disassembled and demultiplexed SDU on the configured logical channels }
}
(2)
with { UE in E-UTRA RRC_IDLE state and after transmitting a RRCConnectionRequest message }
ensure that {
when { UE receives a MAC PDU on DL SCH and addressed to its CRNTI with value '00011'B as LCID }
then { UE shall forward the disassembled and demultiplexed SDU on the corresponding logical channel }
}
}

EXCEPTION: IF UE is Release 8 or Release 9, steps 1 and 2 are repeated for decreasing reserved LCID values from 01011 to 11011 ELSE IF UE is Release 10 onwards, steps 1 and 2 are repeated for decreasing reserved LCID values from 01011 to 11010. |

// 从UE能力上看，UE is Release10, 所以LCID的范围是01011(11) – 11010(26) 2017 Jan 9 08:10:54.001 [DE] 0xB0C0 LTE RRC OTA Packet -- UL_DCCH / UECapabilityInformation 
// UE 收到 ACTIVATE TEST MODE, the TEST MODE is MODE A: DRB 
// UE 发送 ACTIVATE TEST MODE COMPLETE, 但是APEX上没有该LOG显示 // UE 收到 CLOSE UE TEST LOOP，开始闭环还回测试 
// UE发送CLOSE UE TEST LOOP COMPLETE，同样APEX上也没有显示 |

The SS transmits a valid MAC PDU containing a RLC PDU except for LCID in MAC Header set to reserved value . |

// UE MAC 收到 LCID=11的MAC PDU, UE丢弃 
// UE MAC 收到 LCID=12的MAC PDU, 可以看出LCID的变化为生序，UE丢弃 
// UE MAC 收到 LCID=25的MAC PDU, UE丢弃。但是这是最后一包保留LCID的MAC PDU.这与协议是不相符的，协议规定对于LTE R10，最后一包保留LCID=26. 这应该是安利仪表的一个bug.
