  • PDCCH physical downlink control channels

  • the UE In the RRC_Connected state, the UE needs to continuously monitor the physical downlink control channel PDCCH (such as the PDCCH scrambled by the C-RNTI) to learn the downlink PDSCH transmission information.

  • the packet-based data flow is usually bursty. There is data transmission for a period of time, but there is no data transmission for a long period of time. Continuous monitoring of the PDCCH will inevitably lead to rapid power consumption of the UE. Therefore, when there is no data transmission, the power consumption can be reduced by stopping receiving the PDCCH (the blind PDCCH detection will be stopped at this time). Therefore, the design of 3GPP is to achieve the purpose of power saving through DRX (Discontinuous Reception) mechanism, as shown in Figure 1.
  • DRX Continuous Reception
  • the UE In the DRX cycle, the UE only monitors the PDCCH during the reception on period (On duration), and during the discontinuous reception time (Opportunity for DRX), that is, the DRX deactivation period (DRX OFF), the UE does not receive the PDCCH to reduce power consumption To enter sleep mode.
  • NR Rel-16 introduces the group common PDCCH as the energy-saving signal before the DRX activation period (DRX ON).

技术领域
本申请涉及通信技术领域，尤其涉及信号传输方法及装置。
背景技术
5G新的无线(New Radio，NR)系统中，目前终端(User Equipment，UE)的工作状态分为三种：空闲状态(RRC_IDLE)、非激活状态(RRC_Inactive)和连接状态(RRC_Connected)。只有处于RRC_Connected的UE才允许检测例如小区无线网络临时标识(Cell-Radio Network Temporary Identifier，C-RNTI)加扰的物理下行控制信道(Physical Downlink Control Channel，PDCCH)。鉴于NR终端在RRC_Connected模式(mode)的功耗对系统功耗具有决定影响，故NR版本16(Rel-16)对连接态的UE节能(power saving)进行了标准化。在RRC_Connected状态，UE需要持续的监听物理下行控制信道PDCCH(如C-RNTI加扰的PDCCH)，以获知下行PDSCH的发送信息。而基于包的数据流通常是突发性的，在一段时间内有数据传输，但在接下来的一段较长时间内没有数据传输，持续的监听PDCCH必然导致UE的快速耗电。故在没有数据传输的时候，可以通过停止接收PDCCH(此时会停止PDCCH盲检)来降低功耗。因此3GPP的设计是通过DRX(Discontinuous Reception，非连续接收)机制达到省电目的，如图1所示。在DRX周期内，UE只在接收打开周期(On duration)内监测PDCCH，在非连续接收时间(Opportunity for DRX)即DRX去激活周期(DRX OFF)时间内，UE不接收PDCCH，以减少功耗， 即进入睡眠模式。
NR Rel-16在DRX激活周期(DRX ON)之前引入基于组公共(group common)PDCCH作为节能信号，该PDCCH在DRX OFF内传输，且以节能无线网络临时标识(Power saving RNTI，PS-RNTI)加扰，只有节能信号中携带UE唤醒指示，UE才会在其后的DRX周期内唤醒接收机，否则Rel-16的UE将继续睡眠。需要指出的是，RRC-connected mode在DRX OFF内传输的基于group common PDCCH的节能信号，其下行控制信息(Downlink Control Information，DCI)格式重用了Rel-15中DCI格式(format)2_x(x＝0,1,2,3)的设计，即组内每个UE的节能信息是分离的，每个UE节能信息占用一个分组，基站高层信令会通知UE分组的起点及其长度，多个UE对应的多个节能信息分组串行级联构成整个DCI。
根据Rel-16标准，如果UE在DRX激活周期(DRX ON)周期之前解出节能信号，则唤醒接收机在紧接着的DRX周期(cycle)内执行PDCCH检测(monitoring)操作，否则在后续的DRX cycle内执行睡眠操作。但是，如果连续多个DRX cycle，都没有数据传输，则UE无法执行信道状态信息(Channel State Information，CSI)报告(report)，与发送探测参考信号(Sounding Reference Signal，SRS)，导致UE无法反馈链路质量，无法对节能信号进行链路自适应，在DRX ON初期也无法获得上行定时信息，无法快速上行同步。Rel-16处理的方法是在DRX OFF内默认UE不执行CSI report及其SRS发送，除非高层信令配置UE在DRX OFF内执行CSI report及其SRS发送，但是一旦高层信令如此配置，将导致UE在每个DRX OFF周期都要醒来，将较大的损失节电性能。同时，连续多个DRX周期UE都处于睡眠状态，还可能会对UE的接收波束准确性及其无线资源管理(Radio Resource Management，RRM)测量链路维持性能造成破坏性影响。

下面结合说明书附图对本申请各个实施例进行详细描述。需要说明的是，本申请实施例的展示顺序仅代表实施例的先后顺序，并不代表实施例所提供的技术方案的优劣。
参见图2，在网络侧，例如在基站侧，本申请实施例提供的一种信号传输方法包括：
S101、确定需要发送的节能信号；
其中，所述节能信号包括用于指示终端进入唤醒状态的第一指示信息，以及所述第一指示信息对应的第一节能信息，或者，所述节能信号包括用于指示终端进入睡眠状态的第二指示信息，以及所述第二指示信息对应的第二节能信息；
也就是说，本申请实施例中所述节能信号包括用于指示终端进入睡眠或唤醒状态的指示信息，以及所述指示信息对应的节能信息，其中，当所述指示信息为用于指示终端进入唤醒状态的指示信息时，所述指示信息对应的节能信息包括为终端处于唤醒状态时配置的第一节能信息；当所述指示信息为用于指示终端进入睡眠状态的指示信息时，所述指示信息对应的节能信息包括为终端处于睡眠状态时配置的第二节能信息；
S102、发送所述节能信号给终端。
具体说明如下：
首先明确如下概念：
Active Time:即DRX ON周期，即激活期；
outside Active Time：即DRX OFF duration也称为去激活期。
无论是第一节能信息还是第二节能信息，都是在DRX OFF即去激活期内发送的。只不过R16power saving信号标准化了，一个基于UE group的DCI，即多个UE的对应的节能信息在一个DCI中承载，假设第一UE对应5比特节能信息，第二UE对应4比特节能信息，第三UE对应6比特节能信息，基站将这5、4、6比特串行级联在一起构成DCI。对每个UE来说，节能信息的第一个比特称为唤醒指示，比如，其值为1表示在后续的DRX周期内唤醒该UE，其值为0表示在后续的DRX周期内，UE不唤醒接收机进行睡眠。传输节能信号的位置是在每个DRX cycle之前的去激活期即前一个DRX cycle的DRX OFF内。R16中当UE被指示为睡眠时，该UE对应的m比特节能信息中第一比特即唤醒指示为0，剩余的m-1比特也为零(垃圾比特)，既然UE被指示睡眠，则节能信息不携带除了唤醒指示外的任何节能信息。而本申请实施例中，UE被指示为唤醒时，剩余的m-1比特表示Scell dormancy(辅小区睡眠)信息，而指示睡眠时，剩余的m-1比特用于指示其他信息，使其变为有用信息。
可选地，基站可以利用高层信令为UE配置节能信息，包括第一节能信息和第二节能信息，其中，第一节能信息包括为UE配置被指示为唤醒时的节能信息；第二节能信息包括为UE配置UE被指示睡眠时携带的信息，即节能信号携带的除了睡眠指示信息之外的信息，所述节能信号例如可以是在DRX OFF周期内发送的PDCCH，当UE被指示进入睡眠状态时，其对应的DCI比特仍然存在，只不过目前协议中为全零，也就是现有技术中对睡眠UE只指示睡眠指示信息，其他节能信息不携带，而本申请实施例中还通过DCI比特携带其他节能信息(即上述第二节能信息)。
也就是说，该方法还包括：
基站通过高层信令发送所述第一节能信息和/或所述第二节能信息的配置 信息。例如：基站通过高层信令为UE配置所述第一节能信息和/或所述第二节能信息在group common节能信号中的位置及其对应的节能信息类型。例如基站在DRX ON内利用RRC信令为每个UE配置所述第一节能信息和/或所述第二节能信息在节能信号中的起点、长度、以及唤醒指示信息为唤醒状态时，后面m-1个比特对应的节能信息的类型；基站利用RRC信令为UE配置节能信息中，唤醒指示信息为睡眠状态时，剩余m-1个比特中所承载的信息的位置及其类型，例如：m＝5，波束信息占据唤醒指示信息后紧接的2比特，而CSI-report指示信息占据波束指示信息后的一个比特，加上唤醒指示信息共4个比特，最后一个比特没有分配节能信息。以上只是举例说明，不排除其他配置方法。基站必须通过物理层节能信号发送节能信号，例如通过物理层PDCCH发送节能信号。
可选地，基站在DRX OFF时间内，利用节能信号(例如物理层节能信号或信道(例如PDCCH))携带节能信息，即第一节能信息，第一节能信息包括如下内容相关信息中的至少一项：
UE接收波束信息或基站发送波束信息；
信道跟踪参考信号(Tacking RS，TRS)发送；
信道状态信息上报(CSI report)；
物理层RSRP测量(L1-RSRP measurement)；
探测参考信号(SRS)发送；
其中，上述内容相关信息，可以是上述内容本身，也可以是上述内容的指示信息或配置信息。
其中，RSRP为参考信号接收功率(Reference Signal Receive Power)。
可选地，基站在DRX OFF时间内，通过节能信号(例如物理层节能信号或信道(例如PDCCH))携带UE被指示为睡眠时的配置信息，即上述第二节能信息。
可选地，所述的UE被配置为睡眠时携带的信息，即第二节能信息，包括如下内容相关信息中的至少一项：
UE接收波束信息或基站发送波束信息；
TRS发送；
CSI report；
L1-RSRP measurement；
SRS发送；
其中，上述内容相关信息，可以是上述内容本身，也可以是上述内容的指示信息或配置信息。
参见图3，在终端侧，本申请实施例提供的一种信号传输方法包括：
S201、接收节能信号；
其中，所述节能信号包括用于指示终端进入唤醒状态的第一指示信息，以及所述第一指示信息对应的第一节能信息，或者，所述节能信号包括用于指示终端进入睡眠状态的第二指示信息，以及所述第二指示信息对应的第二节能信息；
S202、根据节能信号指示执行节能操作。
可选地，该方法还包括：
通过高层信令获取所述第一节能信息和/或所述第二节能信息的配置信息。
可选地，根据节能信号指示执行节能操作，例如包括：若所述节能信号中携带用于指示终端进入唤醒状态的第一指示信息，则进一步解析所述第一节能信息；若所述节能信号中携带用于指示终端进入睡眠状态的第二指示信息，则进一步解析所述第二节能信息。也就是说，如果UE检测到节能信号,且被唤醒，则在后续DRX周期内唤醒接收机执行PDCCH monitoring(监听)操作；否则UE在后面DRX周期继续保持睡眠状态，不执行PDCCH monitoring操作。
UE首先解码节能信号(节能信号可以是序列，也可以是一个PDCCH信道，解码PDCCH就是解码节能信号，节能信号所携带的信息称为节能信息，从PDCCH中解析出DCI，即解析出节能信息)，如果唤醒指示信息指示UE唤醒，UE根据高层指示解析唤醒状态对应的节能信息(即第一节能信息)； 如果唤醒指示信息指示UE进入睡眠状态，UE根据高层指示解析睡眠状态对应的指示信息(即第二节能信息)。
如果节能信息(可以是上述第一节能信息，也可以是上述第二节能信息)携带了波束指示信息，UE在后续信号或信道接收中按照节能信号携带的发送波束指示信息更新接收波束。
上述节能信息(可以是上述第一节能信息，也可以是上述第二节能信息)还可以携带TRS指示。
下面给出几个实施例的具体举例说明。
实施例1：
如前背景技术部分所述，目前Rel-16标准化了基于group common PDCCH的节能信号，节能信号中携带了多个UE节能信息分组的串行级联。Rel-16标准中每个UE的信息分组由两部分构成，第一部分：UE唤醒指示信息，第二部分：辅小区睡眠(SCells dormancy)指示信息。其中UE唤醒指示由1比特构成，两个状态分别表示UE在紧邻的DRX cycle内执行唤醒操作，还是睡眠操作；SCells dormancy指示信息则指示了UE在被唤醒后，在那些SCells上执行PDCCH monitoring操作。所以目前的标准，当UE没有被唤醒时，其对应的信息分组第一部分，例如为比特0，表示UE在后续DRX内不醒来，第二部分SCells dormancy指示信息一定是全零比特。所以，当UE被指示睡眠时，该UE对应的节能信息分组为全零比特，这些零比特虽然没有任何用处，但还是作为开销必须发送。考虑到同时被节能信号唤醒的UE个数往往较少，这无疑导致DCI的巨大浪费。
因此，本申请实施例中，基站可以进一步利用该节能信息，虽然UE被指示为睡眠状态。基站利用高层信令，例如无线资源控制(Radio Resource Control，RRC)信令或者媒体接入控制单元(MAC CE)为UE配置节能信息，为UE配置“被指示为唤醒时的节能信息”，即第一节能信息，和/或，为UE配置“UE被指示睡眠时携带的信息”，即第二节能信息。
相应地，UE侧的行为：
UE首先解码节能信号，如果唤醒指示信息指示UE为唤醒，UE根据高层指示解析的唤醒状态时对应节能信息；如果唤醒指示信息指示UE为睡眠，UE根据高层指示解析的睡眠状态时对应节能信息。
如果基站没有为UE配置“UE被指示睡眠时携带的信息”，其默认状态为UE睡眠时其对应的位于节能信号DCI中的信息比特分组为全零或者NULL。
实施例2：
如实施例1所述，UE的节能信息分组为RRC信令预先配置的，基站可以为基站配置UE被指示为唤醒时的节能信息(即第一节能信息)，当然唤醒指示本身就是节能信息的一部分；基站还为节能信息指示为睡眠的UE配置其他指示信息(即第二节能信息)，因为UE被节能信号指示为唤醒时，DRX ON定时器(timer)开始启动，而UE被指示睡眠时，UE配置的DRX cycle中DRX ON timer不启动，故此时上述UE被指示为睡眠状态时，节能信号携带的信息在DRX ON timer不启动时生效。在DRX ON timer不生效时UE不执行PDCCH monitoring操作，UE无法获得发送/接收波束更新信息。因为Rel-15与Rel-16中波束更新信息，即传输配置信息(transmission configuration information，TCI)状态(state)，在连接态时通过RRC信令配置给UE，然后通过MAC CE进行更新，但是UE在没有数据到达时，会被节能信号指示在其后的DRX周期内进入睡眠状态，UE在睡眠状态内，即非激活时间(Active Time)内，不会执行PDCCH检测，基站无法传输MAC CE更新的波束信息。当连续多个DRX cycle，UE都被指示处于睡眠状态时，无法对发送波束信息和/或接收波束信息进行更新。由于节能信号是针对一组UE的，其中组内有的UE处于睡眠状态，有的处于唤醒状态，唤醒状态的UE可能已经被基站指示更新了发送波束信息或者接收波束信息，处于睡眠状态的UE则无法接收波束更新信息，所以当基站有数据向该UE发送时，该UE大概率都无法正确接收利用更新后波束发送的节能信号。所述波束信息，可选地是指控制资源集合(control resource set，CORESET)的发送波束，基站通知UE所配置的 CORESET发送波束，终端即可利用对应接收波束进行接收发送信号。在Rel-16节能信号设计中，虽然即使为UE配置多个发送机会，每个发送机会对应一个CORESET，但是目前一个UE最多配置三个CORESET，而且还有一个CORESET有时需要配置成专用于波束失败恢复(beam failure recovery)过程，不能配置给节能信号；因此基站在Active time需要经常更新节能信号对应的CORESET的发送波束，处于睡眠状态的UE会无法收到所述波束更新。可选地，当UE被配置了DRX，基站通过RRC信令配置，当UE被节能信号指示为睡眠时，所对应的节能信息分组中包含为该UE配置的发送/接收的波束信息的起始位置与大小(发送波束是从基站角度看，接收波束是从终端角度看)。基站利用物理层节能信号在指示UE执行UE睡眠操作的同时携带发送和/或接收波束信息，该发送和/或接收波束信息可以包含基站为节能信号配置的一个或者多个CORESET对应的发送波束信息。
节能信号指示UE处于睡眠状态时，节能信号还可以携带TRS、CSI report、L1-RSRP measurement、SRS信息。节能信号在UE睡眠期间触发TRS(Tracking RS)，例如，可利用UE在DRX OFF内接收寻呼(paging)之前的精同步过程。节能信号可在UE睡眠期间触发CSI-RS report，UE可以在DRX ON timer不启动时进行CSI-report利于基站或者节能信号的信道状况，从而对节能信号进行链路自适应。节能信号可在UE睡眠期间触发周期的L1-RSRP measurement，UE可以在DRX ON timer不启动时进行周期的L1-RSRP measurement执行RRM测量过程。节能信号可在UE睡眠期间触发SRS发送，UE可以在DRX ON timer不启动时发送SRS信号，利于基站或者UE的上行同步信息。总之，基站指示UE执行睡眠操作时可以携带链路维持消息，充分利用节能信号。
本申请实施例提供的方案并不排除基站在指示UE被唤醒时在节能信号中携带下列内容相关信息之一或组合：UE接收波束信息或基站发送波束信息、TRS发送、CSI report、L1-RSRP measurement、SRS发送。其中，上述内容相关信息，可以是上述内容本身，也可以是上述内容的指示信息或配置信息。
实施例3：
UE侧接收节能信号，根据节能信号指示执行节能操作。
UE首先解码节能信号，如果唤醒指示信息指示UE为唤醒，UE根据高层指示解析唤醒状态对应的节能信息；如果唤醒指示信息指示UE为睡眠，UE根据高层指示，解析睡眠状态对应的指示信息。
如果唤醒指示信息指示UE为睡眠对应的节能信息中携带了波束指示信息，后续信号/信道接收中按照节能信号携带的新的发送波束更新接收波束。如果UE节能信息还携带了TRS或CSI report或L1-RSRP measurement或SRS发送指示/配置信息，则UE在后续的DRX ON timer没有启动的DRX周期内，按照节能信号的指示接收TRS信号或者执行周期的CSI report或者执行周期的L1-RSRP measurement或者发送周期的SRS信号。
综上所述，本申请实施例中，基站利用高层信令为UE配置节能信息，除了为UE配置被指示为唤醒时的节能信息，还为UE配置UE被指示睡眠时携带的信息，从而可以充分利用Rel-16节能信号指示UE睡眠时的无用DCI比特达到改善接收质量与维持链路的目的。
