唤醒信号WUS(Wake Up Signal)是3GPP在R16中为5G(NR)引入的一种省电机制。试图通过让终端(UE)继续休眠(即不唤醒)来节省电力,用于在DRX OnDuration期间:
DCI 2_6用于通知一个或多个UE在DRX活动时间之外的省电信息。这是由PS-RNTI加扰DCI format2_6的结构如下:Block1, Block2,…, Block N,每个Block结构如下: RRC参数与WUS直接或间接相关RRC参数如下,其中DPC-Config-r16(标记为红色)是最关键的参数。 DRX-Config ::= SEQUENCE { drx-onDurationTimer CHOICE { subMilliSeconds INTEGER (1..31), milliSeconds ENUMERATED { ms1, ms2,...... ms1600, spare8, ...... spare1 } }, drx-InactivityTimer ENUMERATED { ms0, ms1, ...... ms2560, spare9,......spare1}, drx-HARQ-RTT-TimerDL INTEGER (0..56), drx-HARQ-RTT-TimerUL INTEGER (0..56), drx-RetransmissionTimerDL ENUMERATED { sl0, sl1, sl2, ......, sl320, spare15, spare14,...... spare2, spare1}, drx-RetransmissionTimerUL ENUMERATED { sl0, ...... sl128, sl160, sl320, spare15, ...... spare1 }, drx-LongCycleStartOffset CHOICE { ms10 INTEGER(0..9), ....... ms10240 INTEGER(0..10239) }, shortDRX SEQUENCE { drx-ShortCycle ENUMERATED { ms2, ms3, ........ ms640, spare9,...... spare1 }, drx-ShortCycleTimer INTEGER (1..16) } OPTIONAL, -- Need R drx-SlotOffset INTEGER (0..31)} DRX-Preference-r16 ::= SEQUENCE { preferredDRX-InactivityTimer-r16 ENUMERATED { ms0, ms1, ....... ms2560, spare9, ...... spare1} OPTIONAL, preferredDRX-LongCycle-r16 ENUMERATED { ms10, ms20, ....... ms10240, spare12, s....... spare2, spare1 } OPTIONAL, preferredDRX-ShortCycle-r16 ENUMERATED { ms2, m....... ms640, spare9...... spare1 } OPTIONAL, preferredDRX-ShortCycleTimer-r16 INTEGER (1..16) OPTIONAL} PhysicalCellGroupConfig ::= SEQUENCE { .. dcp-Config-r16 SetupRelease { DCP-Config-r16 } OPTIONAL, -- Need M ...} DCP-Config-r16 ::= SEQUENCE { // DCP stands for DCI with CRC scrambled by PS-RNTI ps-RNTI-r16 RNTI-Value, ps-Offset-r16 INTEGER (1..120), sizeDCI-2-6-r16 INTEGER (1..maxDCI-2-6-Size-r16), ps-PositionDCI-2-6-r16 INTEGER (0..maxDCI-2-6-Size-1-r16), ps-WakeUp-r16 ENUMERATED {true} OPTIONAL, -- Need S ps-TransmitPeriodicL1-RSRP-r16 ENUMERATED {true} OPTIONAL, -- Need S ps-TransmitOtherPeriodicCSI-r16 ENUMERATED {true} OPTIONAL -- Need S}
