本公开主张在2021年04月02日在中国提交的中国专利申请号No.202110363813.7的优先权,其全部内容通过引用包含于此。
技术领域
本公开涉及无线技术领域,特别涉及一种物理下行控制信道(Physical Downlink Controlled Channel,PDCCH)监听方法、装置、终端及网络侧设备。
背景技术
随着用户需求和移动通信系统应用场景的变化,新空口(New Radio,NR)系统某些业务对时延有着较高的要求,如超高可靠低时延通信(Ultra-Reliable&Low Latency Communication,uRLLC)业务、扩展现实(eXtend Reality,XR)业务等。对于XR业务,可以理解为一种宽带的uRLLC业务,或者uRLLC+增强移动宽带(enhanced Mobile Broadband,eMMB)业务,不但要求类似于uRLLC支持低时延高可靠,还需要类似增强移动宽带(Enhanced Mobile Broadband,eMMB)支持大带宽与高吞吐。考虑到XR设备(device)例如手持终端,支持XR的智能穿戴设备,例如头戴XR设备或者XR眼镜都是电池供电的,且尺寸受限,因此XR device的功耗节省对实际产品的广泛推广至关重要。
此外,对于时延敏感的低时延特性的业务如扩展现实(eXtend Reality,XR)业务(下文统称低时延业务),为了满足时延与可靠性的关键绩效指标(Key Performance Indicator,KPI),必然要求采用更短的帧结构,所以R15标准化的微时隙调度(mini-slot based scheduling,又称为基于非时隙调度non-slot based scheduling)是改善XR业务的时延性能的必选方案。
微时隙调度虽然能够有效地降低时延,但也会大大增加下行物理控制信道监听机会(PDCCH Monitoring Occasion,PDCCH MO)密度。

具体实施方式
下面将结合本公开实施例中的附图,对本公开实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本公开一部分实施例,而不是全部的实施例。基于本公开中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本公开保护的范围。
本公开的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换,以便这里描述的本公开的实施例,例如除了在这里图示或描述的那些以外的顺序实施。此外,术语“包括”和“具有”以及他们的任何变形,意图在于覆盖不排他的包含,例如,包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
本公开实施例中术语“和/或”,描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。本公开实施例中术语“多个”是指两个或两个以上,其它量词与之类似。
在本公开实施例中,“示例性的”或者“例如”等词用于表示作例子、例证或说明。本公开实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确 切而言,使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
下面结合附图介绍本公开的实施例。本公开实施例提供的模式指示方法、终端设备及网络设备可以应用于无线通信系统中。该无线通信系统可以为采用第五代(5th Generation,5G)移动通信技术的系统(以下均简称为5G系统),所述领域技术人员可以了解,5G NR系统仅为示例,不为限制。
参见图1,图1是本公开实施例可应用的一种网络系统的结构图,如图1所示,包括用户终端11和网络侧设备12,其中,用户终端11可以是用户设备(User Equipment,UE),例如:可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant,简称PDA)、移动上网装置(Mobile Internet Device,MID)或可穿戴式设备(Wearable Device)等终端侧设备,需要说明的是,在本公开实施例中并不限定用户终端11的具体类型。上述网络侧设备12可以是5G及以后版本的基站(例如:NR节点(NR Node B,gNB)、5G NR NB),或者其他通信系统中的基站,或者称之为节点B,需要说明的是,在本公开实施例中仅以5G基站为例,但是并不限定基站12的具体类型。
为清楚说明本公开实施例所述PDCCH监听方法,以下先对PDCCH发送时的PDCCH监听机会进行说明。
通常,终端监听PDCCH的传输机会由资源集(CORESET)和搜索空间(Search Space)共同确定,无线资源控制(Radio Resource Control,RRC)连接模式下,基站通过专用RRC信令会为终端每一带宽部分(BandWidth Part,BWP)配置关于PDCCH监听的先验知识,即CORESET及其search space。配置信息至少包括CORESET频域位置、时域占据的正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号数、PDCCH的聚合等级、位置和下行控制信息(Downlink Control Information,DCI)格式等。终端根据高层信令配置的DCI格式在对应PDCCH监听机会上执行PDCCH盲检操作。
另外,搜索空间确定PDCCH监听的绝对时间位置,搜索空间以时隙为单位配置PDCCH监听周期,时隙内以14bit位图指示PDCCH监听机会起始符号。例如,PDCCH监听周期为一个时隙,资源集CORESET持续时间为2 个OFDM符号,时隙内PDCCH监听图样为01000010000100。
NR PDCCH用解调参考信号(Demodulation Reference Signal,DMRS)解调。DMRS在PDCCH映射到的每个资源单元组(Resource element group,REG)内都存在,密度为1/4,即每个REG内都有3个DM-RS。DM-RS序列加扰初始值通过RRC信令配置CORESET确定,每个CORESET可以独立地配置DM-RS序列加扰初始值。
针对时延敏感的低时延特性的业务如XR业务,采用微时隙调度改善业务的时延性能,但采用微时隙调度,终端在所有的PDCCH监听机会上都要进行PDCCH盲检,监听PDCCH会增加不必要的终端能耗的问题。例如微时隙调度在一个时隙中最多可有7个PDCCH MO,按照相关标准的技术方法,终端在其所有的PDCCH MO内都要进行PDCCH盲检。
由于XR传输支持大带宽,长传输周期,终端始终在min-slot based PDCCH MO监听PDCCH会大幅增加不必要的终端能耗。基于此,在目前的终端节能项目中,为了降低终端功耗,研究与标准化了相应技术方案如节能信号触发非连续接收(Discontinuous Reception,DRX)自适应,跨时隙调度(cross slot scheduling)等技术,但是这些节能技术主要针对时延不敏感业务,以时延换取节能增益,对于时延敏感业务需要从新的维度研究终端节能方案。
本公开实施例提供一种PDCCH监听方法,网络侧设备向终端发送高层配置信息,使终端在激活期内时,接收用于指示终端是否需要在对应的PDCCH监听机会上进行PDCCH监听的监听指示信息,根据该监听指示信息,进行PDCCH监听,以支持实现PDCCH监听的减少,以避免需要在所有的PDCCH监听机会上都要进行PDCCH盲检,造成终端能耗较高的问题,从而解决时延敏感业务的能耗问题。
本公开其中一实施例提供一种PDCCH监听方法,由终端执行,如图2所示,包括:
S210,获取网络侧设备发送的信令;
S220,根据所述信令,在激活期内接收监听指示信息;其中,所述监听指示信息用于指示所述终端是否需要在对应的PDCCH监听机会上进行PDCCH监听;
S230,根据所述监听指示信息,进行PDCCH监听。
本公开实施例中,可选地,所述高层配置信令用于指示终端在激活期内进行监听指示信息的接收,以能够根据监听指示信息确定是否需要在PDCCH监听机会上进行PDCCH监听,避免需要在所有的PDCCH监听机会上都要进行PDCCH盲检,解决时延敏感业务的能耗问题。
可选地,所述信令为高层配置信令。
可选地,所述PDCCH监听方法,在步骤S230,根据所述监听指示信息,进行PDCCH监听,包括:
若接收到所述监听指示信息,则在对应的PDCCH监听机会上进行PDCCH监听;
若未接收到所述监听指示信息,则放弃对应的PDCCH监听机会上PDCCH的监听。
采用该实施方式,监听指示信息为触发在相应的PDCCH监听机会上进行PDCCH监听的信息,根据是否接收到监听指示信息,确定是否需要在相应的PDCCH监听机会上进行PDCCH的监听。
其中一实施方式,可选地,监听指示信息由在与PDCCH监听机会相关联的预设资源上发送的指示信号承载。
采用该实施方式,监听指示信息用于指示是否需要在该预设资源相关联的PDCCH监听机会上进行PDCCH监听。
本公开实施例所述PDCCH监听方法,可选地,所述高层配置信令中包括PDCCH发送资源的类型指示信息;
其中,根据所述高层配置信令,在激活期内接收监听指示信息,包括:
在根据所述类型指示信息,确定PDCCH发送资源为第一类型时,在激活期内,与所述第一类型的PDCCH发送资源的PDCCH监听机会相关联的预设资源上检测所承载的指示信号,获得所述监听指示信息。
该实施方式,网络侧设备可以根据终端能力,对PDCCH发送资源进行分类,以区分是否支持PDCCH监听减少,这样网络侧设备在与PDCCH监听机会相关联的预设资源上发送指示信号,该指示信号用于承载监听指示信息,以指示终端是否需要在预设资源相关联的PDCCH监听机会上进行PDCCH监 听。
可选地,该实施方式中,所述方法还包括:
若根据所述类型指示信息,确定PDCCH发送资源为第二类型,或者PDCCH发送资源并非为所述第一类型,则不执行所述PDCCH监听机会相关联的预设资源上指示信号的检测,直接根据所述PDCCH监听机会进行PDCCH监听。
具体地,采用该实施方式,所述PDCCH监听方法,第一类型的PDCCH发送资源为支持PDCCH监听减少,对于该第一类型的PDCCH发送资源,网络侧设备在终端的激活期内,与PDCCH监听机会相关联的预设资源上发送指示信号,通过指示信号所承载的监听指示信息,指示终端是否需要进行PDCCH监听。对于第一类型外的第二类型的PDCCH发送资源,或者没有配置为第一类型的PDCCH发送资源,网络侧设备可以保持通常的PDCCH发送行为,也即终端不执行PDCCH监听机会相关联的预设资源上指示信号的检测,直接根据所述PDCCH监听机会进行PDCCH监听。
本公开实施例所述PDCCH监听方法,高层配置信令可以通过显式方式或隐式方式,指示终端所配置的PDCCH发送资源的类型。
可选地,其中一实施方式,类型指示信息为高层配置信令中定义的用于指示资源类型的配置参数。具体地,通过高层配置信令中定义的配置参数,用于以显式方式指示资源类型。举例说明,对于用于确定PDCCH监听机会的资源集CORESET,在CORESET的配置中增加配置参数,用于指示PDCCH发送资源的资源类型;对于用于确定PDCCH监听机会的搜索空间,在搜索空间的配置中增加配置参数,用于指示PDCCH发送资源的资源类型。
可选地,另一实施方式,所述类型指示信息通过解调参考信号DMRS的加扰序列初始值参数配置为预设指定值指示所述第一类型。
具体地,网络侧设备与终端可以约定一个专属DM-RS加扰初始值(DMRS-dedicated-value)。其中,在向终端发送资源配置时,通过将DM-RS加扰序列初始值参数配置为预设指定值,如可以表示为监听还原专用值(PDCCH Monitoring Reduction-dedicated-value),用于隐式指示相应的PDCCH发送资源为第一类型;可选地,通过将DM-RS加扰序列初始值参数 配置为常规值,用于指示相应的PDCCH发送资源为第二类型,或者为第一类型之外的其他类型。
举例说明,在通过高层配置信令给终端配置CORESET#n时,通过将DM-RS加扰序列初始值参数配置为预设指定值PDCCH Monitoring Reduction-dedicated-value,来隐式指示发送资源类型为第一类型。其中,该预设指定值PDCCH Monitoring Reduction-dedicated-value可以是一个新增的专用无线网络临时标识(Radio Network Temporary Identifier,RNTI),该RNTI值可通过高层信令配置RNTI时配置给终端。
本公开实施例所述PDCCH监听方法,可选地,预设资源上承载的指示信号包括以下至少之一:
对应第一类型的PDCCH发送资源的专属DMRS;
基于序列的指示信号。
采用本公开实施例所述PDCCH监听方法,在终端的激活期内,网络侧设备向终端发送指示信号,指示信号上承载监听指示信息,且所发送的该指示信号与PDCCH监听机会相关联,用于指示终端是否需要在相关联的PDCCH监听机会上进行PDCCH监听。
其中一实施方式,可选地,网络侧设备向终端发送专属DMRS作为该指示信号,可选地,该专属DMRS为对应第一类型的PDCCH发送资源的DMRS。
具体地,专属DMRS是第一类型的PDCCH发送资源对应的专用身份标识号(Identity document,ID)的函数,即专属DMRS是对应第一类型的发送资源专用的。可选地,可将第一类型的PDCCH发送资源对应的DMRS加扰序列初始值配为专用值,也可配置一个低时延业务专用的RNTI作为DMRS加扰序列初始值,或者,将为与第一类型的PDCCH发送资源对应的业务配置的专用RNTI作为DMRS加扰序列初始值,采用该专用的RNTI生成专属DMRS。
可选地,本公开实施例所述PDCCH监听方法,在终端的激活期内,每一第一类型的PDCCH发送资源所对应的PDCCH监听机会上都包括DMRS,作为所述指示信号,用于承载监听指示信息。
举例说明,基站也即网络侧设备,通过高层专用信令配置CORESET#n 时,配置一个参数隐式或显式指示CORESET类型,通过指示CORESET的类型,用来区分CORESET#n是否支持PDCCH监听减少。具体地,通过高层专用信令隐式或显式指示CORESET类型为第一类型,也即该第一类型为支持PDCCH监听减少,需要在对应的PDCCH监听机会上检测承载监听指示信息的指示信号的资源类型。其中,CORESET类型的指示方式,可以参阅以上的描述,在此不再详细说明。
在CORESET#n为第一类型时,支持PDCCH监听减少,则在CORESET#n内发送PDCCH时,在该CORESET内发送专属的DMRS,以指示终端进行PDCCH监听;若CORESET#n为第二类型或未配置为第一类型,则保持现有PDCCH发送行为。
另一实施方式,网络侧设备通过高层信令配置搜索空间时,通过搜索空间的配置参数隐式或显式指示搜索空间类型,此处类型用来区分搜索空间是否支持PDCCH监听减少。
具体地,在搜索空间被配置为第一类型时,为支持PDCCH监听减少,需要在对应的PDCCH监听机会上检测承载监听指示信息的指示信号。具体地,在该搜索空间内发送PDCCH时,在该搜索空间对应的CORESET中发送专属的DM-RS作为指示信号,以指示终端是否进行PDCCH监听;若搜索空间为第二类型或未配置为第一类型,则保持现有PDCCH发送行为。
本公开实施例所述PDCCH监听方法,另一实施方式,在终端的激活期内,每一第一类型的PDCCH发送资源所对应的PDCCH监听机会上包括基于序列的指示信号,用于承载监听指示信息。
可选地,基于序列的指示信号为对应第一类型的PDCCH发送资源的专属信号,或者为对应所述终端的专属信号。
可选地,基于序列的指示信号的发送资源位置可通过协议预设与PDCCH监听机会相关联,且用于该指示信号承载的预设资源与对应的PDCCH监听机会在时域上间隔预设数量个OFDM符号;或者,所述预设资源与PDCCH监听机会的发送资源频分复用。
举例说明,网络侧设备通过高层专用信令配置CORESET#n时,配置一个参数隐式或显式指示CORESET类型,通过指示CORESET的类型,用来 区分CORESET#n是否支持PDCCH监听减少。具体地,通过高层专用信令隐式或显式指示CORESET类型为第一类型,也即该第一类型为支持PDCCH监听减少,需要在对应的PDCCH监听机会上检测承载监听指示信息的指示信号的资源类型。
在CORESET#n为第一类型时,支持PDCCH监听减少,则在CORESET#n内发送PDCCH时,在PDCCH发送位置对应的预设资源上,发送一个序列信号,以指示终端进行PDCCH监听;若CORESET#n为第二类型或未配置为第一类型,则保持现有PDCCH发送行为。
另一实施方式,网络侧设备通过高层信令配置搜索空间时,通过搜索空间参数隐式或显式指示搜索空间类型,此处类型用来区分搜索空间是否支持PDCCH监听减少。
具体地,在搜索空间被配置为第一类型时,为支持PDCCH监听减少,用于指示需要在对应的PDCCH监听机会上检测承载监听指示信息的指示信号,则在该搜索空间内发送PDCCH时,在PDCCH发送位置对应的预设资源上,发送一个序列信号,作为用于PDCCH监听的指示信号;若搜索空间为第二类型或未配置为第一类型,则保持现有PDCCH发送行为,保持现有PDCCH发送行为。
本公开实施例所述PDCCH监听方法,可选地,承载所述指示信号的所述预设资源对应与一个PDCCH监听机会相关联,或者承载所述指示信号的所述预设资源对应与至少两个PDCCH监听机会相关联。
可选地,在承载所述指示信号的所述预设资源对应与至少两个PDCCH监听机会相关联时,根据所述监听指示信息,进行PDCCH监听,包括:
根据所述监听指示信息,确定与所述预设资源相关联的至少两个PDCCH监听机会是否需要进行PDCCH监听;
在确定至少两个PDCCH监听机会需要进行PDCCH监听时,对每一PDCCH监听机会进行PDCCH监听。
根据以上,以下对采用本公开实施例所述PDCCH监听方法,应用于终端时的具体过程进行说明。
其中一实施方式,基站通过发送专属DMRS,发送指示信号,以指示终 端进行PDCCH监听。
该实施方式中,终端根据基站配置的CORESET/搜索空间参数,获取PDCCH发送资源的类型。
若PDCCH发送资源的类型为第一类型,终端在激活期内第一类型的PDCCH发送资源确定的所有PDCCH监听机会上先检测DMRS,当检测到专属DM-RS时,在对应PDCCH监听机会上监听PDCCH;当检测到非专属DM-RS或没有检测到DMRS时,跳过对应监听机会;
若PDCCH发送资源为第二类型或没有配置为第一类型,则终端保持现有PDCCH监听行为。
可选地,终端检测基站发送的专属DM-RS序列为第一类型的PDCCH发送资源对应的专用ID的函数。
举例说明,其中一实施方式,终端通过基站配置的CORESET#n参数,获取CORESET资源的类型。若CORESET#n为第一类型,则说明支持PDCCH监听减少,终端在激活期内CORESET#n对应的每个PDCCH监听机会上先对DMRS检测,若检测到专属DM-RS,则在对应PDCCH监听机会中监听PDCCH;若没有检测到DMRS或检测到非专属DMRS,则跳过对应的PDCCH监听机会。若CORESET#n为第二类型或未配置为第一类型,不支持PDCCH监听减少,则终端保持现有PDCCH监听行为。
另一实施方式,终端通过基站配置的搜索空间参数,获取搜索空间类型。若搜索空间为第一类型,说明支持PDCCH监听减少,终端在激活期内所述搜索空间对应的所有PDCCH监听机会上先进行DMRS检测,若检测到专属DM-RS,则在对应PDCCH监听机会中监听PDCCH;若没有检测到DM-RS或检测到非专属DM-RS,则跳过对应的PDCCH监听机会。若搜索空间为第二类型或未配置为第一类型,则不支持PDCCH监听减少,终端保持现有PDCCH监听行为。
再一实施方式,基站通过发送一个基于序列的指示信号(如为时间参考信号(Time Reference Signal,TRS)),发送指示信号,以指示终端进行PDCCH监听。其中,发送该基于序列的指示信号的发送资源与PDCCH监听机会相关联。
采用该实施方式时,终端根据基站配置的CORESET/搜索空间参数,获取PDCCH发送资源类型。
若PDCCH发送资源的类型为第一类型,终端在激活期内第一类型的PDCCH发送资源确定的所有PDCCH监听机会上对应的预设资源上先检测序列信号,当检测到序列信号时,在对应PDCCH监听机会上监听PDCCH;当没有成功检测到序列信号,跳过对应PDCCH监听机会。
若PDCCH发送资源类型为第二类型或没有配置为第一类型,则终端保持现有PDCCH监听行为。
该实施方式中,举例说明,其中一实施方式,终端通过基站配置的CORESET#n参数得知此CORESET类型。若为第一类型,支持PDCCH监听减少,终端通过CORESET#n和对应的搜索空间确定PDCCH监听机会位置,在PDCCH监听机会的对应预设资源上检测用于指示PDCCH监听的指示信号,若成功检测到指示信号,则进行PDCCH的监听;反之,则跳过该PDCCH监听机会。若为第二类型或未配置为第一类型,则不支持PDCCH监听减少,终端保持现有PDCCH监听行为。
另一实施方式,终端通过基站配置的搜索空间参数,获取搜索空间类型。若为第一类型,支持PDCCH监听减少,终端通过所述搜索空间和对应的CORESET确定PDCCH监听机会,在PDCCH监听机会对应的预设资源上检测PDCCH监听指示信号,若成功监测到指示信号,则进行PDCCH的监听;反之,则跳过该PDCCH监听机会。若为第二类型或未配置为第一类型,则不支持PDCCH监听减少,终端保持现有PDCCH监听行为。
以下对采用本公开实施例所述PDCCH监听方法的具体实施过程进行举例说明。
实施方式一
该实施方式一中,通过显式方式配置CORESET的类型为第一类型,通过专属DMRS承载监听指示信息,指示终端在对应的PDCCH监听机会上进行PDCCH监听。
具体地,终端上报终端能力,对于不同的终端能力,基站对PDCCH的发送资源进行相应的分类。基站根据终端能力,利用高层信令可将所有 PDCCH的发送资源配置为其中一种类型如第一类型,也可将部分PDCCH的发送资源配置为第一类型,部分发送资源配置为第二类型,也可以仅将部分PDCCH发送资源配置为第一类型,其他PDCCH发送资源不进行类型配置。为方便描述,本文的所有实施例都假设PDCCH发送资源分为第一类型和第二类型,但本公开保护范围不限于此。
基站通过高层信令为终端配置CORESET#n时,通过一个参数配置来指示是否支持PDCCH监听减少,该参数可以直接配置CORESET#n的资源类型(可配为第一类型:支持PDCCH监听减少;第二类型:不支持PDCCH监听减少)。对于第一类型,基站将CORESET对应的DMRS加扰序列初始值配置为专用值,也可配置一个专用RNTI并作为加扰序列初始值,用于生成专属DMRS,基站在CORESET内发送PDCCH时,发送专属DMRS作为指示信号;对于第二类型的PDCCH发送资源,基站保持相关技术行为,不发送指示信号。
终端通过CORESET的配置参数,直接获取CORESET为PDCCH发送资源的哪一种类型,确定是否支持PDCCH监听减少,并进行相应的PDCCH监听行为,即对于第一类型的PDCCH发送资源,终端在激活期内所有的PDCCH监听机会上先检测专属DMRS,只有成功检测到专属DMRS,才会监听对应的PDCCH;对于第二类型的PDCCH发送资源,终端保持现有PDCCH监听行为。
具体的,终端上报终端能力,基站根据终端能力将配置给终端的PDCCH发送资源进行相应的分类。基站通过高层信令将PDCCH发送资源配置为第一类型和第二类型。可选地,第一类型的PDCCH发送资源可用于低时延业务,第二类型的PDCCH发送资源可用于其他业务。
对于基站侧:
基站通过高层信令配置CORESET#n,如通过资源指示类型(Resource-Type)参数配置。
若Resource-Type被配置为第一类型,则表明CORESET#n可支持PDCCH监听减少;
若Resource-Type被配置为第二类型,则表明CORESET#n不支持PDCCH 监听减少。
可选地,基站在配置第一类型的CORESET对应的DMRS加扰序列初始值时,将DMRS加扰序列初始值配置为专属值,可直接协议约定一个专属值,也可配置一个专属RNTI作为DMRS加扰序列初始值,以此生成专属DM-RS。
在第一类型的CORESET内发送PDCCH时,将专属DMRS映射到对应资源上,发送专属DMRS作为指示信号。在第二类型的CORESET内发送PDCCH时,基站保持现有行为。
对于终端侧:
终端通过高层信令获得CORESET#n的配置,通过参数Resource-Type直接得知发送资源类型,得知是否支持PDCCH监听减少。
若Resource-Type为第一类型,终端在激活期内CORESET#n对应的所有PDCCH监听机会上先进行DMRS检测;
若成功检测到专属DM-RS,则表明基站发送了该终端的PDCCH,在对应PDCCH监听机会上进行PDCCH监听;
若未成功检测到专属DM-RS,则表明基站未发送该终端的PDCCH,跳过此PDCCH监听机会。
若Resource-Type为第二类型,终端在CORESET#n内保持相关技术的PDCCH监听行为。
通常技术中,每一次PDCCH盲检都要先假定DMRS存在,执行信道估计,然后DCI译码,如果循环冗余校验(Cyclic Redundancy Check,CRC)校验正确才算成功。PDCCH盲检是并行处理的,比如基站配置了聚合等级及其每个聚合等级的候选PDCCH数,终端需要并行盲检所有的候选PDCCH,不能在某个候选PDCCH上监听到PDCCH就停止监听。与相关技术相比,采用本公开实施例所述方法,对于第一类型的PDCCH发送资源,终端在监听PDCCH之前,先进行极低功耗的DMRS检测来判断是否要进行高功耗的PDCCH监听,能够节省终端大量不必要的PDCCH监听功耗,达到终端省电的目的。此外,通过专属DM-RS作为指示信号的优点在于,可避免终端在支持PDCCH监听减少的CORESET上检测到其他终端的DMRS,导致误以为基站发送了该终端的PDCCH,进行了不必要的PDCCH监听。具体原因为: 如果基站给不同终端配置了相同的DMRS加扰初始值,CORESET配置有重叠,那么终端对不同聚合等级的候选PDCCH进行DMRS检测时,有可能会在其他终端较低聚合等级的候选PDCCH上成功检测到DMRS,就会误以为基站发送了该终端的PDCCH,从而进行了不必要的PDCCH监听。本公开将专属DM-RS作为指示信号,可有效避免不必要的PDCCH监听。
实施方式二
该实施方式二中,通过配置DM-RS加扰序列初始值参数,隐式向终端配置CORESET类型;通过专属DMRS承载监听指示信息,指示终端在对应的PDCCH监听机会上进行PDCCH监听。
可选地,该实施方式中,基站与终端约定一个专属DM-RS加扰初始值DMRS-dedicated-value。
基站通过高层信令为终端配置CORESET#n时,通过将DM-RS加扰序列初始值参数(pdcch-DMRS-ScramblingID)配置为预设指定值PDCCH Monitoring Reduction-dedicated-value或常规值,来隐式指示发送资源类型。可选地,PDCCH Monitoring Reduction-dedicated-value可以为一个新增的专用RNTI,该RNTI值可通过高层信令配置RNTI时配置给终端。
具体地,在解调参考信号DMRS的加扰序列初始值参数配置为PDCCH Monitoring Reduction-dedicated-value,也即配置为预设指定值时,用于指示发送资源类型为第一类型,支持PDCCH监听减少;DMRS的加扰序列初始值参数配置为常规值时,用于指示发送资源类型为第二类型,不支持PDCCH监听减少。
对于第一类型的PDCCH发送资源,基站在CORESET内发送PDCCH时,发送专属DMRS作为指示信号,专属DMRS是由PDCCH Monitoring Reduction-dedicated-value作为加扰初始值生成的;对于第二类型的PDCCH发送资源,基站保持相关技术行为,不发送指示信号。
终端通过判断CORESET配置参数pdcch-DMRS-ScramblingID是否为PDCCHMonitoringReduction-dedicated-value,间接得知CORESET发送资源类型,确定是否支持PDCCH监听减少,并进行相应的PDCCH监听行为。
具体的,终端上报终端能力,基站根据终端能力将配置给终端的PDCCH 发送资源进行相应的分类。基站通过高层信令将PDCCH发送资源配置为第一类型和第二类型,第一类型的PDCCH发送资源可用于低时延业务,第二类型的PDCCH发送资源可用于其他业务。
基站侧:
基站通过专用高层信令配置CORESET#n,配置DMRS加扰序列初始值参数pdcch-DMRS-ScramblingID,若pdcch-DMRS-ScramblingID被配置为PDCCH MonitoringReduction-dedicated-value,则表明发送资源类型为第一类型,CORESET#n支持PDCCH监听减少;
若pdcch-DMRS-ScramblingID被配置为常规值,则表明发送资源类型为第二类型,CORESET#n不支持PDCCH监听减少。
基站通过PDCCH Monitoring Reduction-dedicated-value作为加扰序列初始值生成DM-RS,则该DMRS为专属DMRS。在该CORESET#n内发送PDCCH时,将专属DMRS映射到对应资源上,发送专属DMRS作为指示信号。对于第二类型的PDCCH发送资源,基站保持现有行为。
终端侧:
终端通过高层信令获得CORESET#n的配置参数,通过参数pdcch-DMRS-ScramblingID间接得知是否支持PDCCH监听减少,并进行相应的PDCCH监听行为,若pdcch-DMRS-ScramblingID为常规值,终端在CORESET#n内保持相关技术的PDCCH监听行为。若pdcch-DMRS-ScramblingID为PDCCH Monitoring Reduction-dedicated-value,终端在CORESET#n内的PDCCH监听机会上先对DMRS进行检测。
若成功检测到专属DM-RS,则表明基站发送了该终端的PDCCH,进行PDCCH的监听;
若未成功检测到专属DM-RS,则表明基站未发送该终端的PDCCH,跳过该PDCCH监听机会。
由于本实施例采用专属DM-RS作为指示信号,DMRS的加扰初始序列在CORESET配置参数中,参数pdcch-DMRS-ScramblingID配成专用值,既可以用作专属DM-RS的加扰,也可以用来指示CORESET的发送资源类型。该实施方式所述方法除了具有与实施方式一相同的有益效果之外,与实施方 式一采用新增参数显式指示发送资源类型相比,实施方式二采用隐式方式指示发送资源类型,能够不增加信令开销。
实施方式三
该实施方式三中,配置搜索空间的类型,并通过专属DMRS承载监听指示信息,指示终端在对应的PDCCH监听机会上进行PDCCH监听。
该实施方式中,基站通过高层信令为终端配置搜索空间时,通过一个参数配置来指示是否支持PDCCH监听减少,此参数显式或隐式指示搜索空间资源类型(第一类型:支持PDCCH监听减少;第二类型:不支持PDCCH监听减少)。对于第一类型,基站在搜索空间内发送PDCCH时,发送专属DM-RS作为指示信号,对于第二类型,基站保持相关技术行为,不发送指示信号。
终端通过搜索空间的配置参数,获取搜索空间资源类型,得知是否支持PDCCH监听减少,并进行相应的PDCCH监听行为,即对于第一类型的PDCCH发送资源,终端在其所有的PDCCH监听机会上先检测专属DMRS,只有成功检测到专属DMRS,才会监听对应的PDCCH;对于第二类型的PDCCH发送资源,终端保持现有PDCCH监听行为。
具体的,终端上报终端能力,基站根据终端能力将配置给终端的PDCCH发送资源进行相应的分类。基站通过高层信令将PDCCH发送资源配置为第一类型和第二类型,第一类型的PDCCH发送资源可用于低时延业务,第二类型的PDCCH发送资源可用于其他业务。
对于基站侧:
基站通过专用高层信令配置搜索空间SS#n时,配置参数指示PDCCH发送资源类型,若发送资源类型为第一类型,则表明该SS#n支持PDCCH监听减少;若发送资源类型为第二类型,则表明该SS#n不支持PDCCH监听减少。
基站用SS#n关联的CORESET对应的DM-RS加扰序列初始值生成DM-RS,将其映射到所述CORESET资源发送。对于第一类型,该DMRS为专属DM-RS,作为PDCCH监听指示信号;对于第二类型,该DMRS不作为指示信号。
对于终端侧:
终端通过高层信令获得搜索空间SS#n的配置参数,获取搜索空间的发 送资源类型,若发送资源类型为第二类型,终端在搜索空间SS#n内保持相关技术的PDCCH监听行为。
若发送资源类型为第一类型,终端在SS#n内的PDCCH监听机会上先对DMRS进行检测;
若检测到专属DM-RS,则表明基站在PDCCH监听机会上发送了该终端的PDCCH,进行PDCCH的监听;
若未成功检测到专属DM-RS,则表明基站在PDCCH监听机会上未发送该终端的PDCCH,跳过对应PDCCH MO。
需要说明的是,采用该实施方式三所述方法的有益效果,与实施方式一和实施方式二相同,在此不再详细说明。
实施方式四
该实施方式中,配置CORESET参数通知类型,基于序列信号指示PDCCH监听。
基站通过高层信令为终端配置CORESET#n时,通过一个配置参数标识CORESET#n的发送资源类型,指示是否支持PDCCH监听减少(第一类型:支持PDCCH监听减少;第二类型:不支持PDCCH监听减少)。对于第一类型的PDCCH发送资源,基站根据配置的CORESET和对应的搜索空间确定PDCCH监听机会,并在与PDCCH监听机会相关联的预设资源处发送一个基于序列的信号,作为PDCCH监听指示信号。可选地,每一PDCCH监听机会都关联一个预设资源用来发送指示信号。
终端通过所配置的CORESET和对应的搜索空间,确定PDCCH监听机会,通过高层信令获得所配置发送资源的类型,对于第一类型,终端根据PDCCH监听机会与预设资源的关系,还可以确定预设资源的位置。终端先在预设资源上检测PDCCH监听指示信号,根据检测结果判断是否在相应的PDCCH监听机会进行PDCCH监听。对于第二类型,终端保持现有PDCCH监听行为。
具体的,终端上报终端能力,基站根据终端能力将配置给终端的PDCCH发送资源进行相应的分类。基站通过高层信令将PDCCH发送资源配置为第一类型和第二类型,第一类型的PDCCH发送资源可用于低时延业务,第二 类型的PDCCH发送资源可用于其他业务。
对于基站侧:
基站通过专用高层信令配置CORESET#n,配置参数指示发送资源类型。
若发送资源类型为第一类型,则表明CORESET#n支持PDCCH监听减少;
若发送资源类型为第二类型,则表明CORESET#n不支持PDCCH监听减少。
基站在CORESET#n对应的PDCCH监听机会上发送PDCCH,对于第一类型,基站发送PDCCH时,还需在与PDCCH监听机会关联的预设资源上发送一个基于序列的指示信号,此预设资源位置与PDCCH监听机会之间的关系可以是时域上相隔若干个OFDM符号,也可以是在频域上频分复用。
对于终端侧:
终端通过专用高层信令获得CORESET#n的配置,得知CORESET#n的发送资源类型,若发送资源类型为第二类型,终端在CORESET#n内保持相关技术的PDCCH监听行为。
若发送资源类型为第一类型,终端根据CORESET#n和对应的搜索空间确定PDCCH监听机会位置,在每个PDCCH监听机会对应的预设资源位置上进行序列信号检测。
若成功检测到基站发送的基于序列的指示信号,则表明对应PDCCH监听机会内存在该终端的PDCCH,进行PDCCH的监听;
若未能成功检测出基站发送的基于序列的指示信号,则认为对应PDCCH监听机会内不存在该终端的PDCCH,跳过该PDCCH监听机会。
与相关技术相比,采用实施方式四所述方法,通过与PDCCH MO关联的预设资源位置上发送基于序列的PDCCH监听指示信号,终端可根据PDCCH监听指示信号位置确定指示信号的预设资源的位置,通过极低能耗的指示信号检测,来避免不必要的高能耗的PDCCH监听。
实施方式五
该实施方式中,通过搜索空间的配置参数指示搜索空间的类型,并基于序列信号指示PDCCH监听。
其中,基站通过高层信令为终端配置搜索空间SS#n时,通过一个配置参数标识搜索空间SS#n的发送资源类型,指示是否支持PDCCH监听减少(第一类型:支持PDCCH监听减少;第二类型:不支持PDCCH监听减少)。对于第一类型,基站根据配置的搜索空间和对应的CORESET确定PDCCH监听机会,并在与PDCCH监听机会关联的预设资源发送一个基于序列的信号,作为PDCCH监听指示信号。每个PDCCH监听机会都关联一个预设资源用来发送指示信号。
终端通过所配置的搜索空间和对应的CORESET,确定PDCCH监听机会,通过高层信令得知所配置发送资源的类型,对于第一类型,终端根据PDCCH监听机会与预设资源的关系,还可以确定预设资源的位置。终端先在预设资源上检测PDCCH监听指示信号,根据检测结果判断是否在相应的PDCCH监听机会进行PDCCH监听。对于第二类型,终端保持现有PDCCH监听行为。
具体的,
终端上报终端能力,基站根据终端能力将配置给终端的PDCCH发送资源进行相应的分类。基站通过高层信令将PDCCH发送资源配置为第一类型和第二类型,第一类型的PDCCH发送资源可用于低时延业务,第二类型的PDCCH发送资源可用于其他业务。
对于基站侧:
基站通过专用高层信令配置搜索空间SS#n,配置参数指示发送资源类型;
若发送资源类型为第一类型,则表明搜索空间SS#n支持PDCCH监听减少;
若发送资源类型为第二类型,则表明搜索空间SS#n不支持PDCCH监听减少。
基站在搜索空间SS#n对应的PDCCH监听机会发送PDCCH,对于第一类型,基站发送PDCCH时,还需在与PDCCH监听机会关联的预设资源上发送一个基于序列的指示信号,此预设资源位置与PDCCH监听机会之间的关系可以是时域上相隔若干个OFDM符号,也可以是在频域上频分复用。
对于终端侧:
终端通过专用高层信令获得搜索空间SS#n的配置,得知搜索空间SS#n的发送资源类型,若发送资源类型为第二类型,终端在搜索空间SS#n内保持相关技术的PDCCH监听行为。
若发送资源类型为第一类型,终端根据搜索空间SS#n和对应的CORESET确定PDCCH监听机会位置,在每个PDCCH监听机会对应的预设资源位置上进行序列信号检测;
若成功检测到基站发送的基于序列的指示信号,则表明对应PDCCH监听机会内存在该终端的PDCCH,进行PDCCH的监听;
若未能成功检测出基站发送的基于序列的指示信号,则认为对应PDCCH MO内不存在该终端的PDCCH,则跳过该PDCCH监听机会。
需要说明的是,实施方式五所述方法与实施方式四所述方法,具有相同的有益效果,在此不再详细说明。
采用本公开实施例所述方法,根据终端能力,可将所有发送资源配置为其中一种类型,也可将部分发送资源配置为第一类型,部分发送资源配置为第二类型。对于第一类型的PDCCH发送资源,指示信号与PDCCH监听机会绑定或关联,终端可根据每个PDCCH监听机会的资源位置确定指示信号的资源位置;终端在每个预设资源上检测指示信号来判断在对应PDCCH监听机会中是否监听PDCCH。与相关技术在终端所有PDCCH监听机会内都进行PDCCH的监听相比,本公开所述方法通过极低能耗的PDCCH监听指示信号检测,避免了终端不必要的PDCCH监听,省去了不必要的监听PDCCH的高能耗,延长了终端的电池寿命和提高了用户终端体验。
