  • the functions of the terminal are increased, and the terminal (User Equipment, UE) may need to support different services at different moments, resulting in the terminal's frequency of use becoming more frequent and further increasing power consumption.
  • UE User Equipment
  • the energy consumption of the terminal is mainly focused on two aspects:
  • the terminal needs to wake up at each paging occasion (PO) to listen to the Physical Downlink Control Channel (PDCCH), but because the base station does not necessarily configure a paging message for the terminal, the terminal is at Detecting the PDCCH phase consumes a lot of energy.
  • PO paging occasion
  • PDCCH Physical Downlink Control Channel
  • Scheduling-free PDCCH (PDCCH without grant): In a radio resource control (RRC) connected state, the terminal blindly detects the PDCCH, but does not have scheduling information of the terminal, and consumes a lot of energy.

  • the terminal manufacturers Even if a part of the energy-saving mechanism is introduced in the NR, the terminal manufacturers still believe that the power consumption of the connected state occupies most of the power consumption of the terminal.
  • the main consumption of the power consumption of the connected state is that the terminal needs to blindly detect all of the power at the PDCCH detection time.
  • PDCCH candidate to obtain PDCCH scheduling information but in most cases, the terminal performs a blind check, but because there is currently no actual effective uplink or downlink scheduling information, that is, the base station does not actually send the control channel, or the base station only A small part of the many possibilities of PDCCH detection was sent, and the interruption did not have any prior information, which caused the terminal to consume more power during the blind detection.

技术领域
本公开涉及通信技术领域,尤其是指一种指示信令的传输、接收方法、装置、网络侧设备及终端。
背景技术
在5G系统中,终端需要检测的带宽更宽,速率更大,导致终端的功耗比长期演进(Long Term Evolution,LTE)更大;另一方面,随着新空口(New Radio,NR)支持的功能增多,终端(User Equipment,UE)在不同的时刻可能需要支持不同的业务,导致终端的使用频率变得更加频繁,也会进一步增大功耗。
终端的能量消耗主要集中于两个方面:
寻呼:终端需要在每个寻呼时机(paging occasion,PO)醒来监听物理下行控制信道(Physical Downlink Control Channel,PDCCH),但是由于基站并不一定为该终端配置了寻呼消息,终端在检测PDCCH阶段会消耗大量的能量。
免调度的PDCCH(PDCCH without grant):在无线资源控制(Radio Resource Control,RRC)连接态下,终端盲检PDCCH,但是并没有该终端的调度信息,消耗了大量能量。
相关技术中的一些节能的方案主要包括:
一、对于空闲态(idle态)的节能
在蜂窝物联网领域,已经讨论了终端节能的技术,在空闲态下,引入唤醒信号(wake up signal,WUS)进行节能,通过WUS指示终端是否需要检 测接下来的寻呼时机(paging occasion,PO)。如果终端检测到WUS,才继续检测寻呼PDCCH;如果终端没有检测到WUS,终端就不会检测接下来的寻呼时机(paging occasion,PO)。
WUS信号采用131长度的ZC(Zadoff-chu)序列,携带有小区标识(小区ID),通过高层配置WUS的最大时域持续时长,并且会配置WUS与调度寻呼消息的PDCCH之间的间隔(gap),如图1所示。由于NB(Narrow Band)是窄带系统,因此WUS频域上占用NB的全部带宽,时域上占用一个子帧,即1ms。
二、对于连接态(connected态)的节能
LTE中采用RRC连接状态下配置DRX(Connected Discontinuous Reception,C-DRX)来达到节能与时延性能的平衡,对于不同的终端,可能有不同的业务类型和业务到达模型,通过为不同的终端设置不同的参数来匹配不同用户的需求。
但是C-DRX的调整是半静态的调整,相对缓慢;另一方面即使在C-DRX模式下,终端检测PDCCH的功耗比例也是相当高的。
控制信道检测支持不同的参数配置,如不同的控制信道检测周期,不同的控制信道检测候选个数等,虽然能够进行参数调整,但均通过高层信令进行调整,调整周期相对较长。
即便在NR中引入了部分的节能机制,但各终端厂商仍然认为连接态的功耗占据终端功耗的大部分,对于连接态的功耗主要消耗的在于终端需要在PDCCH检测时刻去盲检所有的PDCCH候选,以获得PDCCH的调度信息,但大部分情况下,终端进行了盲检,但由于当前并没有实际有效的上行或下行调度信息,即基站实际并未发送控制信道,或是基站只发送了PDCCH检测的众多可能性中的少部分,而中断并没有任何先验信息,导致终端在盲检时消耗了较多的功耗。
NB中的WUS设计主要用来解决空闲状态用户检测无效PDCCH的能耗问题。对于NR,物理层节能技术重在考虑连接态的节能技术。
一方面WUS占用系统全部带宽和整个子帧的设计不再适用,NR的系统带宽将大到几百兆,占用全部带宽显然开销太大。对于连接态,控制信道的 调度频率是时隙级别的。而空闲态的寻呼周期是几十,几百毫秒级别的。如果为每次控制信道调度都增加一个时隙级别(LTE的时域调度单位是子帧,包括15KHz子载波间隔的14个即正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号,NR的时域调度单位是时隙或迷你时隙,一个时隙不论子载波间隔大小均包含14个OFDM符号)的唤醒信号开销也将无法承受。
另一方面,NR连接态的控制信道检测复杂度来源于各个方面,比如检测的频率、检测的控制信道候选个数、检测的带宽等各个方面。窄带物联网(Narrow Band Internet of Things,NB-IOT)系统中的WUS设计只需要指示是否需要检测寻呼信道的PDCCH。
另外,配置了DRX的连接态节能由于参数配置由高层配置,参数调整不灵活,节能效果无法快速的适配终端的业务类型,因此也需要进行优化设计。
综上,NB中的WUS设计无法满足NR的连接态的节能设计需要。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。
如图2所示,本公开实施例提供一种指示信令的传输方法,应用于网络侧设备,包括:
步骤21,在目标物理资源或目标下行控制信道上发送指示信令,所述指示信令包括至少一个终端的检测信息,所述检测信息包括以下至少之一:
第一指示信息,用于指示接下来的至少一个非连续接收(Discontinuous Reception,DRX)周期内的激活状态;
第二指示信息,用于指示接下来的至少一个DRX周期的DRX参数的配置;
第三指示信息,用于指示待检测的下行控制信道的检测状态信息;
第四指示信息,用于指示接下来的至少一个寻呼时机的检测状态。
本公开的上述实施例中,通过指示信令指示至少一个终端的检测信息(或称为检测参数),该指示信息可以是通过目标物理资源承载,也可以通过目标下行控制信道承载;终端基于指示信令的指示进行控制信道检测,减少不必要的检测。
作为一个实施例,通过目标物理资源承载指示信令时,该指示信令采用 简单的编码,例如信息比特与编码比特存在直接的映射关系的编码方式(比如通过表格列出其映射关系),不需要像控制信道那样进行Polar编码;再例如,信息比特进行重复或其他低码率的编码方式。
即上述步骤21包括:
使用信息比特与编码比特存在映射关系的编码方式对指示信令进行编码;和/或,使用信息比特进行重复或低码率的信道编码方式对所述指示信令进行编码;
在所述目标物理资源或目标下行控制信道上发送编码后的所述指示信令。
进一步的,目标物理资源的时域OFDM符号的位置包括:
时隙的第一个正交频分复用OFDM符号(即目标物理资源映射到时隙的第一个OFDM符号上);和/或,
传输下行控制信道的控制信道资源集合(Control Resource Set,CORESET)所在的OFDM符号(即目标物理资源映射到传输下行控制信道的CORESET所在的OFDM符号上)。
需要说明的是,CORESET在时域上持续符号个数最大为3个OFDM符号,时域的起始位置由搜索空间配置确定。
进一步需要说明的是,目标物理资源可以映射到传输下行控制信道的CORESET所在的全部OFDM符号上,也可以映射到传输下行控制信道的CORESET所在的部分OFDM符号上。
具体的,本公开的上述实施例中,目标物理资源的频域资源映射单位为:
下行控制信道的资源粒子组(Resource Element Group,REG);或者,
N个资源块RB;N为大于或者等于1的整数。可选的,N等于6。由高层以6RB为资源粒度通过多比特指示分配该目标物理资源的频域位置。以6RB为映射单元的优点在于能够跟控制信道资源集合(control resource set,CORESET)的资源分配兼容。因为CORESET的频域资源分配为通过bitmap(位图)的形式指示以6PRB为一组的资源组是否分配给CORESET。
如图3所示,目标物理资源映射到时隙的第一个符号上,并以6RB为频域资源映射单元。如图4所示,目标物理资源映射到传输CORESET所在的OFDM符号上,并以6RB为频域资源映射单元。
需要说明的是,上述目标物理资源的频域资源位置由预定义或者网络侧信令配置的方式确定;和/或,上述目标物理资源的时域OFDM符号的位置由预定义或者网络侧信令配置的方式确定。
作为另一个实施例,通过目标下行控制信道承载指示信令时,该目标下行控制信道包括:
承载公共控制信息的控制信道和/或承载终端专属控制信息的控制信道。
由于公共控制信道的检测候选较少,且候选位置在搜索空间的位置确定,因此其本身的检测复杂度较低。
进一步的,本公开的上述实施例中,在所述目标物理资源或目标下行控制信道上通过序列承载所述指示信令。即所述目标物理资源或目标下行控制信道上承载序列,通过序列来标识其指示信令。对于不同终端的指示信令可以通过不同正交码区分,在相同的传输资源上进行传输。
需要说明书的是,本公开的上述实施例提供的指示信令包含第一指示信息、第二指示信息、第三指示信息以及第四指示信息中的至少一个。
第一方面,在所述指示信令包括第一指示信息的情况下,
所述第一指示信息指示的接下来的至少一个非连续接收DRX周期内的激活状态包括以下至少之一:
在接下来的至少一个DRX周期内满足指定条件的情况下是否启动非连续接收-持续时间定时器drx-onDurationTimer;
在接下来的至少一个DRX周期的激活期内是否检测下行控制信道(例如PDCCH);
在接下来的至少一个DRX周期内满足指定条件的情况下启动drx-onDurationTimer;即终端一旦检测到该信息就需要启动drx-onDurationTimer,如果没有检测到该信息就不需要启动drx-onDurationTimer。
在接下来的至少一个DRX周期的激活期内检测下行控制信道(例如,PDCCH);即终端一旦检测到该信息就需要检测PDCCH,如果没有检测到该信息就不需要检测PDCCH。
其中,指定条件包括下述至少一个:
非连续接收-短周期drx-ShortCycle的情况下,从满足第一约束关系的子 帧的起始位置开始非连续接收-时隙偏移drx-SlotOffset参数表示的时间之后所指示的时间位置;
非连续接收-长周期drx-LongCycle的情况下,从满足第二约束关系的子帧的起始位置开始非连续接收-时隙偏移drx-SlotOffset参数表示的时间之后所指示的时间位置。
简言之,第一指示信息用于指示之后的本该启动drx-onDurationTimer的时期是否检测PDCCH,或是是否要启动drx-onDurationTimer。通俗讲就是on duration阶段终端是否需要唤醒;例如指示信令的某种状态表示其后的on duration阶段终端不需要唤醒接收PDCCH,即本次on duration阶段不会存在PDCCH调度,则终端可以继续保持非激活(inactivity)状态,达到节能的效果。
例如,当使用drx-ShortCycle时,第一约束关系为:满足[(SFN×10)+subframe number]modulo(drx-ShortCycle)=(drx-StartOffset)modulo(drx-ShortCycle);
当使用drx-LongCycle时,第二约束关系为:满足[(SFN×10)+subframe number]modulo(drx-LongCycle)=drx-StartOffset,
在满足上述第一约束关系或第二约束关系的子帧的起始位置开始偏移drx-SlotOffset所指示的时间位置启动drx-onDurationTimer。
通过该第一指示信息就可以指示接下来的这些本该启动drx-onDurationTimer的时间是否启动drx-onDurationTimer;或者,指示在接下来的激活期内是否检测PDCCH。
上述激活期包括38.321中声明的激活期:当配置了DRX时,激活期包括如下这些:
drx-onDurationTimer或drx-InactivityTimer或drx-RetransmissionTimerDL或drx-RetransmissionTimerUL或ra-ContentionResolutionTimer运行期间;或者,
在PUCCH上发送了一个上行调度请求(Scheduling Request,SR),还未收到响应(处于pending阶段);或者,
已经成功收到了一个随机接入响应,此随机接入响应对应的随机接入序 列并不是媒体接入控制(Medium Access Control,MAC)实体从基于竞争的随机接入序列中选择出来的,但还没有收到对应于该MAC实体的小区无线网络临时标识(Cell Radio Network Temporary Identifier,C-RNTI)的PDCCH指示新数据的传输。
第二方面,在所述指示信令包含所述第二指示信息的情况下,
若高层信令配置多套DRX参数配置,所述第二指示信息指示所述高层信令配置的多套DRX参数配置中的一套DRX参数配置为应用于DRX周期的DRX参数配置;
若高层信令配置一套DRX参数配置,所述第二指示信息指示一缩放比例因子,应用于DRX周期的DRX参数由所述高层信令配置的DRX参数配置和所述缩放比例因子确定。
简言之,对DRX参数配置的包括如下两种指示方式:
通过高层信令配置多套的DRX参数配置,每一套参数配置中有部分参数与其他配置不同。该第二指示信息指示其中的一套配置,应用与此次唤醒阶段;实现动态调整DRX参数配置的目的;
高层信令配置1套DRX参数配置,该信令指示一个缩放比例scaling因子,对DRX参数配置中的定时器值或是时隙周期偏移值进行scaling,得到应用于当前on duration唤醒阶段的DRX参数配置。
比如scaling因子为1/8,1/4,1/2,1,2,4,8等数值,对于DRX参数配置中定时器的定时通过scaling因子与高层配置的定时器值相乘,将得到的结果与定时器的取值范围中的可选值相比较,找到最大的定时器值或是比相乘结果小的最大的可选取值,或是比相乘结果大的最小的可选取值作为更新的定时器值。
对于long DRX cycle和short DRX cycle的scaling,long DRX cycle的周期和偏移值是同时定义的,可以将周期和偏移值进行scaling之后进行上述类似的取整操作。Short DRX cycle的取值可以基于高层配置中,与long DRX cycle的比例关系k值,比如long DRX的周期为short DRX cycle的k倍。那么直接将scaling之后的long DRX cycle值除以k值得到short DRX cycle取值;k为预先定义的一数值。
需要说明的是,一套所述DRX参数配置包括以下至少之一:drx-onDurationTimer,非连续接收-静止定时器drx-InactivityTimer,下行非连续接收-混合自动重传请求-往返时间定时器drx-HARQ-RTT-TimerDL,上行非连续接收-混合自动重传请求-往返时间定时器drx-HARQ-RTT-TimerUL,下行非连续接收-重传定时器drx-RetransmissionTimerDL,上行非连续接收-重传定时器drx-RetransmissionTimerUL,非连续接收-长周期起始偏移drx-LongCycleStartOffset,短周期非连续接收shortDRX和非连续接收-时隙偏移drx-SlotOffset。
第三方面,在所述指示信令包含所述第三指示信息的情况下,所述第三指示信息通过下述信息中的至少一个信息的状态取值来指示待检测的下行控制信道的检测状态信息:
待检测的搜索空间的类型;
待检测的搜索空间的候选;
待检测的搜索空间集合;
待检测的搜索空间的无线网络临时标识RNTI类型;
待检测的下行控制信息的格式;以及,
待检测的下行控制信息的长度。
其中,待检测的搜索空间的类型包括:公共搜索空间和/或终端专属的搜索空间。
下行控制信道的检测复杂度,来源于终端同时需要盲检的控制信道配置较多,比如搜索空间类型较多,控制信道格式较多,候选较多等。
因此通过第三指示信息将这些搜索空间类型,下行控制信息(Downlink Control Information,DCI)格式,候选,甚至搜索空间集合(search space set),加扰的RNTI类型进行组合,并将对应的状态取值指示给终端,终端将会根据信令指示省去不必要的检测,只进行部分控制候选的盲检,从而降低终端的检测复杂度。
第三指示信息的设计集合部分或全部上述信息的不同状态取值进行。这里举例以连接态的用户的控制信道检测为例,对于连接态的终端,系统信息只有在固定的时机读取,而且系统消息的变更通过寻呼消息指示,因此,对 于公共搜索空间先不考虑系统消息的检测。可以考虑寻呼消息的控制信道检测(传输P-RNTI(Paging-RNTI)加扰的控制信息),随机接入响应(random access response,RAR)(传输RA-RNTI或TC-RNTI加扰的控制信息)及其他用于时隙格式指示(slot format indicator,SFI),功控命令,中断传输指示(interrupted transmission indicator)等type3公共控制信息的检测。
搜索空间的类型可以分为:公共搜索空间、终端专属的搜索空间,及既需要检测公共搜索空间又需要检测终端专属搜索空间。
下行控制信息的格式,即DCI format可分为:公共搜索空间的包括DCI format 0_0,1_0,2_0,2_1,2_2,2_3。终端专属的搜索空间有DCI format0_1,1_1,0_0,1_0。
这些format可以进一步根据format的DCI长度进行分组,相同分组的做一个状态指示。例如公共搜索空间的DCI format 0_0,1_0,2_2,2_3由于DCI长度相同,可以合并为同一个状态,此时,若指示为该状态,则根据搜索空间的配置,如果这些格式的搜索空间的检测位置即监听时机发生在相同的时隙,则UE可能会同时需要盲检多种DCI format。
作为一个可选实施例,待检测的搜索空间的候选的状态取值包括:待检测的搜索空间的候选的比例值、待检测的搜索空间的候选的聚合等级以及待检测的搜索空间的候选的聚合等级组标识中的至少一个;
其中,待检测的搜索空间的候选的聚合等级组包括:待检测的搜索空间的候选的至少两个聚合等级。
例如,搜索空间的候选可以分为搜索空间配置的候选的1/4,1/2,1等比例;即检测时只需要检测前1/4个候选,1/2个候选,全部的候选,还可以包括0比例,即不检测。至于比例的取值可以有其他的设置,最终的候选个数为了保证是整数值,也可以进行上取整或下取整。另一方面,也可以是通知搜索空间候选中只有部分聚合等级的候选需要检测,如将聚合等级进行分类,将相邻的两个聚合等级作为一组{1,2},{2,4},{4,8},{8,16},通过指示信令指示检测第1组,则表示当前只需要检测聚合等级1,2。也可以直接指示盲检的聚合等级。
如果考虑上search space set,可以是所有set的1/4,1/2,1等比例;或是将 配置的search space set按照ID分成不同的组,比如组1对应search space ID0~1,组2对应ID 2~3,组3对应ID 4~5,依次的组5对应8~9。配置的组数和对应的ID情况可以是高层配置的。
作为一个可选实施例,待检测的搜索空间集合的状态取值包括:待检测的搜索空间集合组的索引,和/或,待检测的搜索空间集合的索引;其中,待检测的搜索空间集合组包括:至少两个待检测的搜索空间集合。
可选的,待检测的搜索空间集合组的索引为待检测的搜索空间集合组的组ID,待检测的搜索空间集合的索引为待检测的搜索空间集合ID。
由于不同的search space set可以配置不同的检测周期,大的周期意味着较低的控制信道检测频率,小的周期则意味着较高的控制信道检测频率。每个UE的每个带宽部分(bandwidth part,BWP)最多可以配置10个搜索空间集合,通过为不同的搜索空间集合配置不同的检测周期,通过指示信令指示检测的搜索空间集合的ID,就能够实现动态的控制信道检测周期的变化。例如配置了4个搜索空间集合ID分别为1,2,3,4,对应的检测周期分别为1,2,5,10个时隙。通过指示信令指示在收到信令后的某段时间范围内只需要检测ID为4的搜索空间,那么就动态的实现了PDCCH检测周期的调整。从而降低控制信道检测的复杂度。而当在某一段时间内,UE需要频繁被调度时,通过指示信令指示在某段时间范围内需要ID为1或2的检测搜索空间,实现动态的适应UE业务负载的目的。指示信令指示的搜索空间ID可以为1个,也可以为多个。
为了降低指示的复杂度,也可以是将搜索空间集合按照ID进行分组,不同的分组对应的检测周期的范围可能有所不同。指示检测哪些组实现控制信道检测状态的调整。上文举例不同的组之间ID不重合,还有一种方式是不同的分组内的ID可以有重合。比如组1中对应ID为{0,1,2,3},组2中对应ID为{1,4,5,6},组3为{1,7,8,9}。这种方式,适用于对于某个搜索空间集合的检测是不变的,而其他的控制信息的发送周期或频率是动态调整的,那么相应的可以配置不同的搜索空间集合来适应这种控制信息发送频率的调整,对应不同的搜索空间ID。
本公开一些实施例中,通过指示周期的最小值,实现待检测搜索空间集 合(在38.331协议中表示为Search Space,在38.213中表示为search space set)的指示。例如,配置了4个搜索空间集合ID分别为1,2,3,4,对应的检测周期分别为1,2,5,10个slot时隙。指示后续需要检测的搜索空间周期最小为5,则只需检测周期大于或大于等于5的搜索空间集合3和4。如果指示后续需要检测的搜索空间周期最小为1,则4个搜索空间集合均需要检测。
RNTI类型的区分,比如对于同一类搜索空间还会区分不同的RNTI加扰。但通常相同DCI长度,不同format格式带来的盲检复杂度并不大,因此,RNTI类型区分的节能效果有限。
取如上信息的部分或全部组合,构成第三指示信息的不同的指示状态。例如,第三指示信息包括3比特,如表1所示为第三指示信息包含的内容及对应的状态。
表1
Figure PCTCN2019096082-appb-000001
Figure PCTCN2019096082-appb-000002
以状态取值110为例,指示当前用户仅需要检测终端专属的搜索空间,如果当前时隙正好对应到寻呼时机,由于寻呼消息的控制信息属于公共控制信息,那么说明当前不会有寻呼消息的控制信息发送,用户不需要去检测寻呼消息获取系统消息更新情况。检测的DCI format包括所有的DCI,即DCI format 0_0,1_0,也包括DCI format 0_1,1_1,这种状态适用于用户配置了多个终端专属的搜索空间的情况,因为某个搜索空间只能检测DCI format 0_0,1_0或DCI format 0_1,1_1。只有在多个搜索空间的情况下才会需要同时monitor DCI format 0_0,1_0和DCI format 0_1,1_1。
对于状态101,由于指示只需要检测DCI format 0_1,1_1,那么对于那些配置了检测DCI format 0_0,1_0的搜索空间,用户就不需要进行检测了。
对于状态000,表示当前终端不需要进行控制信道的检测。
具体的表格设计这里仅仅是示例,当前第三指示信息组合了多少种信息,组合了哪几种信息,每个信息的状态划分都可以是高层配置的。
第三指示信息的指示方式也可以根据需要指示的信息类型进行逐比特指示。例如当前指示的组合为2种,包括了search space set和候选比例。假设search space set分成了5组,则用5比特,每比特对应一组,指示哪些search space set需要检测。同时还要指示候选的比例,假设有4种候选比例,则可以有两种方式,一种是对于每组search space set有2比特。另一种是对所有的search space set进行公共的2比特指示。
第三指示信息本身可以是每个终端单独指示,可以是公共的指示。
例如当前第三指示信息指示的组合只包含一种,即PDCCH候选的比例,并且比例状态有3种。那么需要2比特的指示信息。
当采用公共指示时,第三指示信息只包含2比特,检测到该第三指示信息的终端,遵循相同的控制信道检测状态;当采用终端单独指示时,有两种方式,一种是各终端均检测自己的第三指示信息,这种方式开销较大。另一种是多个终端的复用在同一个指示信令中,每个终端对应指示信令中不同的2比特。
第四方面,在指示信令包括第四指示信息的情况下。
该第四指示信息还可以用于RRC IDLE状态的寻呼状态的指示,与WUS的作用类似指示终端寻呼时刻是否有有效的寻呼消息发送,如果没有有效的寻呼消息发送,则终端不需要检测调度寻呼消息的控制信道,可以继续保持低耗电模式,达到节能的效果。不同的是传输资源与WUS不同,WUS占据全部带宽和一个或多个子帧传输,这里的指示信息的传输资源为目标物理资源或目标下行控制信道。
进一步的,需要说明的是,所述指示信令为公共指示信令或终端专用指示信令。
具体的,指示信令发送的方式一种是发送公共的信息,即信令的指示内容对所有终端相同;另一种方式是不同终端在指示信息在信令中占据的比特是不同的,这种指示方式,检测信息对不同的终端可以不同。第三种是每个终端单独指示,指示信令的开销较大。
指示信令可以指示1个或多个时隙的终端需要检测控制信息的情况。也可以指示一个或多个DRX周期的唤醒或者配置信息。
可选的,在所述指示信令为公共指示信令的情况下,
不同终端的检测信息在所述指示信令中对应的比特位相同或不同。
综上,本公开的上述实施例提供一种指示信令的传输方法,动态的指示用户DRX的唤醒状态和DRX参数配置,同时动态的指示哪些控制信道候选需要检测,哪些不需要检测,可以降低用户检测无效PDCCH的次数,从而达到连接态的节能目的。
如图5所示,本公开实施例还提供一种指示信令的接收方法,应用于终端,包括:
接收网络侧设备在目标物理资源或目标下行控制信道上发送的指示信令,所述指示信令包括至少一个终端的检测信息,所述检测信息包括以下至少之一:
第一指示信息,用于指示接下来的至少一个非连续接收DRX周期内的激活状态;
第二指示信息,用于指示接下来的至少一个DRX周期的DRX参数的配 置;
第三指示信息,用于指示待检测的下行控制信道的检测状态信息;
第四指示信息,用于指示接下来的至少一个寻呼时机的检测状态。
作为一个实施例,通过目标物理资源承载指示信令时,该指示信令采用简单的编码,例如信息比特与编码比特存在直接的映射关系的编码方式(比如通过表格列出其映射关系),不需要像控制信道那样进行Polar编码;再例如,信息比特进行重复或其他低码率的编码方式。
即上述步骤51包括:
接收网络侧设备在目标物理资源或目标下行控制信道上发送的编码后的指示信令;
其中,所述网络侧设备使用信息比特与编码比特存在映射关系的编码方式对指示信令进行编码;和/或,使用信息比特进行重复或低码率的信道编码方式对所述指示信令进行编码。
进一步的,目标物理资源的时域OFDM符号的位置包括:
时隙的第一个正交频分复用OFDM符号(即目标物理资源映射到时隙的第一个OFDM符号上);和/或,
传输下行控制信道的控制信道资源集合CORESET所在的OFDM符号(即目标物理资源映射到传输下行控制信道的CORESET所在的OFDM符号上)。
需要说明的是,CORESET在时域上持续符号个数最大为3个OFDM符号,时域的起始位置由搜索空间配置确定。
进一步需要说明的是,目标物理资源可以映射到传输下行控制信道的CORESET所在的全部OFDM符号上,也可以映射到传输下行控制信道的CORESET所在的部分OFDM符号上。
具体的,本公开的上述实施例中,目标物理资源的频域资源映射单位为:
下行控制信道的资源粒子组REG;或者,
N个资源块RB;N为大于或者等于1的整数。可选的,N等于6。由高层以6RB为资源粒度通过多比特指示分配该目标物理资源的频域位置。以6RB为映射单元的优点在于能够跟控制信道资源集合(control resource set, CORESET)的资源分配兼容。因为CORESET的频域资源分配为通过位图(bitmap)的形式指示以6PRB为一组的资源组是否分配给CORESET。
需要说明的是,上述目标物理资源的频域资源位置由预定义或者网络侧信令配置的方式确定;和/或,上述目标物理资源的时域OFDM符号的位置由预定义或者网络侧信令配置的方式确定。
作为另一个实施例,通过目标下行控制信道承载指示信令时,该目标下行控制信道包括:
承载公共控制信息的控制信道和/或承载终端专属控制信息的控制信道。
由于公共控制信道的检测候选较少,且候选位置在搜索空间的位置确定,因此其本身的检测复杂度较低。
进一步的,本公开的上述实施例中,在所述目标物理资源或目标下行控制信道上通过序列承载所述指示信令。即所述目标物理资源或目标下行控制信道上承载序列,通过序列来标识其指示信令。对于不同终端的指示信令可以通过不同正交码区分,在相同的传输资源上进行传输。
需要说明书的是,本公开的上述实施例提供的指示信令包含第一指示信息、第二指示信息、第三指示信息以及第四指示信息中的至少一个。
第一方面,在所述指示信令包括第一指示信息的情况下,
所述第一指示信息指示的接下来的至少一个非连续接收DRX周期内的激活状态包括以下至少之一:
在接下来的至少一个DRX周期内满足指定条件的情况下是否启动非连续接收-持续时间定时器drx-onDurationTimer;
在接下来的至少一个DRX周期的激活期内是否检测下行控制信道;
在接下来的至少一个DRX周期的激活期内是否检测下行控制信道(例如PDCCH);
在接下来的至少一个DRX周期内满足指定条件的情况下启动drx-onDurationTimer;即终端一旦检测到该信息就需要启动drx-onDurationTimer,如果没有检测到该信息就不需要启动drx-onDurationTimer。
在接下来的至少一个DRX周期的激活期内检测下行控制信道(例如,PDCCH);即终端一旦检测到该信息就需要检测PDCCH,如果没有检测到该 信息就不需要检测PDCCH。
其中,指定条件包括下述至少一个:
非连续接收-短周期drx-ShortCycle的情况下,从满足第一约束关系的子帧的起始位置开始非连续接收-时隙偏移drx-SlotOffset参数表示的时间之后所指示的时间位置;
非连续接收-长周期drx-LongCycle的情况下,从满足第二约束关系的子帧的起始位置开始非连续接收-时隙偏移drx-SlotOffset参数表示的时间之后所指示的时间位置。
简言之,第一指示信息用于指示之后的本该启动drx-onDurationTimer的时期是否检测PDCCH,或是是否要启动drx-onDurationTimer。通俗讲就是on duration阶段终端是否需要唤醒;例如指示信令的某种状态表示其后的on duration阶段终端不需要唤醒接收PDCCH,即本次on duration阶段不会存在PDCCH调度,则终端可以继续保持非激活(inactivity)状态,达到节能的效果。
例如,当使用drx-ShortCycle时,满足[(SFN×10)+subframe number]modulo(drx-ShortCycle)=(drx-StartOffset)modulo(drx-ShortCycle);或者,
当使用drx-LongCycle,满足[(SFN×10)+subframe number]modulo(drx-LongCycle)=drx-StartOffset,子帧的起始位置开始偏移drx-SlotOffset所指示的时间位置启动drx-onDurationTimer。
通过该第一指示信息就可以指示接下来的这些本该启动drx-onDurationTimer的时间是否启动drx-onDurationTimer;或者,指示在接下来的激活期内是否检测PDCCH。
上述激活期包括38.321中声明的激活期:当配置了DRX时,激活期包括如下这些:
drx-onDurationTimer或drx-InactivityTimer或drx-RetransmissionTimerDL或drx-RetransmissionTimerUL或ra-ContentionResolutionTimer运行期间;或者,
在PUCCH上发送了一个上行调度请求SR,还未收到响应(处于pending阶段);或者,
已经成功收到了一个随机接入响应,此随机接入响应对应的随机接入序列并不是MAC实体从基于竞争的随机接入序列中选择出来的,但还没有收到对应于该MAC实体的小区无线网络临时标识(Cell Radio Network Temporary Identifier,C-RNTI)的PDCCH指示新数据的传输。
第二方面,在所述指示信令包含所述第二指示信息的情况下,
若高层信令配置多套DRX参数配置,所述第二指示信息指示所述高层信令配置的多套DRX参数配置中的一套DRX参数配置为应用于DRX周期的DRX参数配置;
若高层信令配置一套DRX参数配置,所述第二指示信息指示一缩放比例因子,应用于DRX周期的DRX参数由所述高层信令配置的DRX参数配置和所述缩放比例因子确定。
简言之,对DRX参数配置的包括如下两种指示方式:
通过高层信令配置多套的DRX参数配置,每一套参数配置中有部分参数与其他配置不同。该第二指示信息指示其中的一套配置,应用与此次唤醒阶段;实现动态调整DRX参数配置的目的;
高层信令配置1套DRX参数配置,该信令指示一个缩放比例scaling因子,对DRX参数配置中的定时器值或是时隙周期偏移值进行scaling,得到应用于当前on duration唤醒阶段的DRX参数配置。
比如scaling因子为1/8,1/4,1/2,1,2,4,8等数值,对于DRX参数配置中定时器的定时通过scaling因子与高层配置的定时器值相乘,将得到的结果与定时器的取值范围中的可选值相比较,找到最大的定时器值或是比相乘结果小的最大的可选取值,或是比相乘结果大的最小的可选取值作为更新的定时器值。
对于long DRX cycle和short DRX cycle的scaling,long DRX cycle的周期和偏移值是同时定义的,可以将周期和偏移值进行scaling之后进行上述类似的取整操作。Short DRX cycle的取值可以基于高层配置中,与long DRX cycle的比例关系k值,比如long DRX的周期为short DRX cycle的k倍。那么直接将scaling之后的long DRX cycle值除以k值得到short DRX cycle取值;k为预先定义的一数值。
需要说明的是,一套所述DRX参数配置包括以下至少之一:drx-onDurationTimer,非连续接收-静止定时器drx-InactivityTimer,下行非连续接收-混合自动重传请求-往返时间定时器drx-HARQ-RTT-TimerDL,上行非连续接收-混合自动重传请求-往返时间定时器drx-HARQ-RTT-TimerUL,下行非连续接收-重传定时器drx-RetransmissionTimerDL,上行非连续接收-重传定时器drx-RetransmissionTimerUL,非连续接收-长周期起始偏移drx-LongCycleStartOffset,短周期非连续接收shortDRX和非连续接收-时隙偏移drx-SlotOffset。
第三方面,在所述指示信令包含所述第三指示信息的情况下,所述第三指示信息通过下述信息中的至少一个信息的状态取值来指示待检测的下行控制信道的检测状态信息:
待检测的搜索空间的类型;
待检测的搜索空间的候选;
待检测的搜索空间集合;
待检测的搜索空间的无线网络临时标识RNTI类型;
待检测的下行控制信息的格式;以及,
待检测的下行控制信息的长度。
其中,待检测的搜索空间的类型包括:公共搜索空间和/或终端专属的搜索空间。
下行控制信道的检测复杂度,来源于终端同时需要盲检的控制信道配置较多,比如搜索空间类型较多,控制信道格式较多,候选较多等。
因此通过第三指示信息将这些搜索空间类型,DCI格式,候选,甚至搜索空间集合(search space set),加扰的RNTI类型进行组合,指示给终端,终端将会根据信令指示省去不必要的检测,只进行部分控制候选的盲检,从而降低终端的检测复杂度。
第三指示信息的设计集合部分或全部上述信息的不同状态取值进行。这里举例以连接态的用户的控制信道检测为例,对于连接态的终端,系统信息只有在固定的时机读取,而且系统消息的变更通过寻呼消息指示,因此,对于公共搜索空间先不考虑系统消息的检测。可以考虑寻呼消息的控制信道检 测(传输P-RNTI加扰的控制信息),随机接入响应(random access response,RAR)(传输RA-RNTI或TC-RNTI加扰的控制信息)及其他用于时隙格式指示(slot format indicator,SFI),功控命令,中断传输指示(interrupted transmission indicator)等type3公共控制信息的检测。
搜索空间类型可以分为:公共搜索空间、终端专属的搜索空间,及既需要检测公共搜索空间又需要检测终端专属搜索空间。
下行控制信息的格式,即DCI format可分为:公共搜索空间的包括DCI format 0_0,1_0,2_0,2_1,2_2,2_3。终端专属的搜索空间有DCI format0_1,1_1,0_0,1_0。
这些format可以进一步根据format的DCI长度进行分组,相同分组的做一个状态指示。例如公共搜索空间的DCI format 0_0,1_0,2_2,2_3由于DCI长度相同,可以合并为同一个状态,此时,若指示为该状态,则根据搜索空间的配置,如果这些格式的搜索空间的检测位置即监听时机发生在相同的时隙,则UE可能会同时需要盲检多种DCI format。
作为一个可选实施例,待检测的搜索空间的候选的状态取值包括:待检测的搜索空间的候选的比例值、待检测的搜索空间的候选的聚合等级以及待检测的搜索空间的候选的聚合等级组标识中的至少一个;
其中,待检测的搜索空间的候选的聚合等级组包括:待检测的搜索空间的候选的至少两个聚合等级。
例如,搜索空间的候选可以分为搜索空间配置的候选的1/4,1/2,1等比例;即检测时只需要检测前1/4个候选,1/2个候选,全部的候选,还可以包括0比例,即不检测。至于比例的取值可以有其他的设置,最终的候选个数为了保证是整数值,也可以进行上取整或下取整。另一方面,也可以是通知搜索空间候选中只有部分聚合等级的候选需要检测,如将聚合等级进行分类,将相邻的两个聚合等级作为一组{1,2},{2,4},{4,8},{8,16},通过指示信令指示检测第1组,则表示当前只需要检测聚合等级1,2。也可以直接指示盲检的聚合等级。
如果考虑上search space set,可以是所有set的1/4,1/2,1等比例;或是将配置的search space set按照ID分成不同的组,比如组1对应search space ID 0~1,组2对应ID 2~3,组3对应ID 4~5,依次的组5对应8~9。配置的组数和对应的ID情况可以是高层配置的。
作为一个可选实施例,待检测的搜索空间集合的状态取值包括:待检测的搜索空间集合组的索引,和/或,待检测的搜索空间集合的索引;其中,待检测的搜索空间集合组包括:至少两个待检测的搜索空间集合。
可选的,待检测的搜索空间集合组的索引为待检测的搜索空间集合组的组ID,待检测的搜索空间集合的索引为待检测的搜索空间集合ID。
由于不同的search space set可以配置不同的检测周期,大的周期意味着较低的控制信道检测频率,小的周期则意味着较高的控制信道检测频率。每个UE的每个带宽部分(bandwidth part,BWP)最多可以配置10个搜索空间集合,通过为不同的搜索空间集合配置不同的检测周期,通过指示信令指示检测的搜索空间集合的ID,就能够实现动态的控制信道检测周期的变化。例如配置了4个搜索空间集合ID分别为1,2,3,4,对应的检测周期分别为1,2,5,10个时隙。通过指示信令指示在收到信令后的某段时间范围内只需要检测ID为4的搜索空间,那么就动态的实现了PDCCH检测周期的调整。从而降低控制信道检测的复杂度。而当在某一段时间内,UE需要频繁被调度时,通过指示信令指示在某段时间范围内需要ID为1或2的检测搜索空间,实现动态的适应UE业务负载的目的。指示信令指示的搜索空间ID可以为1个,也可以为多个。
为了降低指示的复杂度,也可以是将搜索空间集合按照ID进行分组,不同的分组对应的检测周期的范围可能有所不同。指示检测哪些组实现控制信道检测状态的调整。上文举例不同的组之间ID不重合,还有一种方式是不同的分组内的ID可以有重合。比如组1中对应ID为{0,1,2,3},组2中对应ID为{1,4,5,6},组3为{1,7,8,9}。这种方式,适用于对于某个搜索空间集合的检测是不变的,而其他的控制信息的发送周期或频率是动态调整的,那么相应的可以配置不同的搜索空间集合来适应这种控制信息发送频率的调整,对应不同的搜索空间ID。
本公开一些实施例中,通过指示周期的最小值,实现待检测搜索空间集合(在38.331协议中表示为Search Space,在38.213中表示为search space set) 的指示。例如,配置了4个搜索空间集合ID分别为1,2,3,4,对应的检测周期分别为1,2,5,10个slot时隙。指示后续需要检测的搜索空间周期最小为5,则只需检测周期大于或大于等于5的搜索空间集合3和4。如果指示后续需要检测的搜索空间周期最小为1,则4个搜索空间集合均需要检测。
RNTI类型的区分,比如对于同一类搜索空间还会区分不同的RNTI加扰。但通常相同DCI长度,不同format格式带来的盲检复杂度并不大,因此,RNTI类型区分的节能效果有限。
第三指示信息的指示方式也可以根据需要指示的信息类型进行逐比特指示。例如当前指示的组合为2种,包括了search space set和候选比例。假设search space set分成了5组,则用5比特,每比特对应一组,指示哪些search space set需要检测。同时还要指示候选的比例,假设有4种候选比例,则可以有两种方式,一种是对于每组search space set有2比特。另一种是对所有的search space set进行公共的2比特指示。
第三指示信息本身可以是每个终端单独指示,可以是公共的指示。
例如当前第三指示信息指示的组合只包含一种,即PDCCH候选的比例,并且比例状态有3种。那么需要2比特的指示信息。
当采用公共指示时,第三指示信息只包含2比特,检测到该第三指示信息的终端,遵循相同的控制信道检测状态;当采用终端单独指示时,有两种方式,一种是各终端均检测自己的第三指示信息,这种方式开销较大。另一种是多个终端的复用在同一个指示信令中,每个终端对应指示信令中不同的2比特。
第四方面,在指示信令包括第四指示信息的情况下。
该第四指示信息还可以用于RRC IDLE状态的寻呼状态的指示,与WUS的作用类似指示终端寻呼时刻是否有有效的寻呼消息发送,如果没有有效的寻呼消息发送,则终端不需要检测调度寻呼消息的控制信道,可以继续保持低耗电模式,达到节能的效果。不同的是传输资源与WUS不同,WUS占据全部带宽和一个或多个子帧传输,这里的指示信息的传输资源为目标物理资源或目标下行控制信道。
进一步的,需要说明的是,所述指示信令为公共指示信令或终端专用指 示信令。
具体的,指示信令发送的方式一种是发送公共的信息,即信令的指示内容对所有终端相同;另一种方式是不同终端在指示信息在信令中占据的比特是不同的,这种指示方式,检测信息对不同的终端可以不同。第三种是每个终端单独指示,指示信令的开销较大。
指示信令可以指示1个或多个时隙的终端需要检测控制信息的情况。也可以指示一个或多个DRX周期的唤醒或者配置信息。
可选的,在所述指示信令为公共指示信令的情况下,
不同终端的检测信息在所述指示信令中对应的比特位相同或不同。
综上,本公开的上述实施例提供一种指示信令的接收方法,网络侧设备动态的指示用户DRX的唤醒状态和DRX参数配置,同时动态的指示哪些控制信道候选需要检测,哪些不需要检测,可以降低终端检测无效PDCCH的次数,从而达到连接态的节能目的。
