Description

一种确定非连续接收配置信息的方法及装置 技术领域
本公开涉及移动通信技术,尤指一种确定实现非连续接收配置信息的方法及装置。
背景技术
长期演进(LTE)/第四代(4G)网络中,基于包的数据流通常是突发性的,即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。在没有数据传输时,可以通过停止接收物理下行控制信道(PDCCH,Physical Downlink Control Channel)(此时会停止PDCCH盲检)来降低功耗,从而提升电池使用时间,上述过程由网络给终端配置一套非连续接收(DRX,Discontinuous Reception)的定时器来实现。如果每个子帧配置一个DRX的激活期,两个激活期之间的时间间隔很短,将达不到省电的目的。如果两个激活期之间的时间间隔很长,可以降低终端功耗,但是将造成较大的数据传输时延。不管有多少个业务,由于网络只给终端配置一套DRX参数,因此,需要在功耗和时延之间进行折中,这样很难适应业务的多样性需求。
未来第五代(5G)移动通信相对于LTE/4G网络,一方面,数据吞吐量大、时延低、可靠性要求也进一步提高,并且业务类型趋向于多样化,传输特性也各异,比如增强型移动互联网(eMBB,enhanced Mobile Broadband)业务需要满足大带宽、高吞吐量,但对时延要求较低;海量连接的物联网(mMTC,massive Machine Type Communications)业务需要网络能支持海量用户连接,用户连接数量成百倍增加;超可靠和低延时的通信(URLLC,Ultra-Reliable and Low Latency Communications)对时延和可靠性要求很高。也就是说,针对实时和非实时业务对终端的DRX参数配置将不一样,以适应不同业务类型的特征和达到时延和功耗两方面的平衡,比如,非时延敏感的业务允许终端尽可能长的时间进入睡眠降低功耗的状态,而时延敏感的业务需要终端经常被唤醒来满足时延要求。
另一方面,未来终端功能越发强大,将能同时进行多种不同类型的业务,比如终端同时进行非时延敏感和时延敏感的业务时,如果按照LTE网络只给终端配置一套DRX参数的实现方式,即仅配置非时延敏感的DRX或时延敏感的DRX,将不能很好地适应终端节电和不同业务特征的传输时延要求。并且,目前DRX都是基于PDCCH或物理下行共享信道(PDSCH,Physical Downlink Shared Channel)的,如果5G移动通信中不同的物理层参数(numerology)对应不同的PDCCH类型,那么也需要有不同的DRX参数与PDCCH类型绑定。
基于上面的分析,相关技术中提供的非连续接收方式,由于不能针对多种业务类型对终端进行灵活的DRX配置,因此,不能适应未来移动通信技术的要求。

本公开的其它特征和优点将在随后的说明书中阐述,并且,部分地从说明书中变得显而易见,或者通过实施本公开而了解。本公开的目的和其他优点可通过在说明书、权利要求书以及附图中所特别指出的结构来实现和获得。
附图说明
此处所说明的附图用来提供对本公开的进一步理解,构成本申请的一部分,本公开的示意性实施例及其说明用于解释本公开,并不构成对本公开的不当限定。在附图中:
图1为相关技术中DRX周期的示意图;

具体实施方式
为使本公开的目的、技术方案和优点更加清楚明白,下文中将结合附图对本公开的实施例进行详细说明。需要说明的是,在不冲突的情况下,本申请中的实施例及实施例中的特征可以相互任意组合。
图1为相关技术中DRX周期的示意图,如图1所示,DRX的基本机制是为处于RRC连接态的终端配置一个DRX周期(DRX-Cycle)。DRX cycle由激活期(On Duration)和休眠期(Opportunity for DRX)组成:在激活期时间内,终端监听并接收PDCCH;在休眠期时间内,终端不接收PDCCH以减少功耗。处于休眠期的终端,只是不接收PDCCH,但是可以接收来自其它物理信道的数据,如PDSCH、确认信息(ACK/NACK)等。比如:在SPS调度中,处于休眠期的终端可以接收周期性配置的下行子帧上发送的PDSCH数据。
DRX cycle的选择需要考虑电池节约与延迟之间的平衡。一方面,长的DRX-Cycle有益于延长终端的电池使用时间,比如网页浏览过程中,当用户正在阅读已经下载好的网页时,终端持续接收下行数据是对资源的浪费。另一方面,当有新的数据传输时,一个更短的DRX-Cycle有益于更快的响应,比如用户请求另一个网页或者进行VoIP通话时。为了满足上述需求,每个终端可以配置两个DRX cycle:短DRX周期(short DRX-Cycle)和长DRX周期(long DRX-Cycle)。如果终端配置了short DRX-Cycle,则long DRX-Cycle应该配置为short DRX-Cycle的倍数。但是,在LTE系统中,任一时刻,终端只能使用其中一种DRX配置。
图2(a)为本公开另一种确定非连续接收配置信息的方法的流程图,如图2(a)所示,包括:
步骤2001:终端接收来自基站配置的不同的业务类型与非连续接收DRX配置信息的映射关系。
本步骤之前还包括:基站生成不同的业务类型与DRX的映射关系,并将映射关系配置给终端。
其中,映射关系包括:业务类型信息与DRX配置信息的映射关系;或者,业务类型信息的DRX索引与DRX配置信息的映射关系。
这里,基站将映射关系配置给终端可以包括:
基站通过L3控制信息和/或L2控制信息半静态地将生成的映射关系指示给终端;
或者,基站通过物理下行控制指示信息动态地将生成的映射关系指示给终端;
这里,基站将映射关系配置给终端也可以包括:
基站半静态和/或动态地同时将多套生成的映射关系发送给所述终端。
步骤2011:终端根据当前使用的业务的业务类型信息及映射关系确定与该业务对应的DRX配置信息。
本步骤中的当前使用即为当前正在进行,也就是缓存(buffer)中有的数据,或者终端收到了对该业务对应的PDCCH或RNTI的调度。
当存在多个业务并发时,可以是合并处理,也可以是独立处理。其中,独立处理包括:根据各业务对应的DRX配置信息分别独立计算各业务对应的激活(active)时间,并在每个计算出的active时间进行接收。其中,合并处理包括:选择一个最小的DRX配置信息,并在其active时间进行业务的接收。
本公开的方法中,业务类型信息包括:
无线承载,和/或逻辑信道,和/或物理层参数;或者,物理信道,和/或无线网络临时标识;
本步骤中的确定与业务对应的DRX配置信息包括:
终端根据无线承载,和/或逻辑信道,和/或物理层参数,以及所述映射关系,确定与业务类型对应的DRX配置信息;或者,
终端根据物理信道,和/或无线网络临时标识,以及所述映射关系,选择所述DRX配置信息。
其中,物理层参数包括至少以下之一:子载波间隔、符号间隔、子帧格式、子帧包含的符号数、多址方式、传输时间间隔;
其中,物理信道包括至少以下之一:物理下行控制信道PDCCH、增强物理下行控制信道ePDCCH、物理下行共享信道PDSCH。
可选地,当业务类型和/或所述逻辑信道和/或所述无线承载和/或所述物理层参数改变时,还包括:
终端根据来自基站的DRX配置信息更新所述映射关系。
可选地,还包括:
终端向基站反馈的接收确认消息;其中,接收确认消息携带有用于指示是否成功接收到所述DRX配置信息的接收状态指示。
图2(b)为本公开另一种确定非连续接收配置信息的方法的流程图,如图2(b)所示,包括:
步骤2002:基站配置不同业务类型与DRX的映射关系。所述映射关系如表1所述。
本步骤中的业务与DRX的映射关系可以包括但不限于:
一种为:无线承载(RB)和/或逻辑信道(LCH)和/或物理层参数与DRX配置信息的映射关系;
或者,另一种为:物理信道和/或无线网络临时标识(RNTI)与DRX配置信息的映射关系。
其中,物理层参数可以包括至少以下之一:子载波间隔、符号间隔、子帧格式、子帧 包含的符号数、多址方式、传输时间间隔。
其中,业务类型可以根据传输速率、和/或时延、和/或可靠性等要求进行划分,包括但不限于至少以下之一:eMBB、mMTC、URLLC等。
其中,物理信道包括但不限于至少以下之一:PDCCH、增强物理下行控制信道(ePDCCH)、物理下行共享信道(PDSCH)。
所述映射关系可以如表1所示:
Figure PCTCN2017104618-appb-000001
表1
所述映射关系也可以如表2所示:
DRX索引 DRX配置信息
1 DRX配置1
2 DRX配置2
n DRX配置n
表2
由于不同类型的业务对传输速率、传输时延等要求不一样,为了满足业务传输特性,需要采用不同的物理层参数(numerology)进行适配,并且,如果5G移动通信中不同的numerology对应不同的PDCCH类型,那么,需要有不同的DRX参数与PDCCH类型绑定,因此,按照本公开实现非连续接收的方法,基站可以为终端生成一套或一套以上DRX参数,每套DRX参数与不同的无线承载和/或逻辑信道和/或物理层参数进行映射。
步骤2012:基站根据当前使用的业务类型信息及映射关系确定出与该业务类型对应的DRX配置信息。
步骤2022:基站将确定出的DRX配置信息发送给终端。
本步骤中,基站可以通过信令(RRC/MAC/PHY)显示指示终端使用哪一种DRX配置信息;或者,基站可以通过当前该终端正在进行的业务选择使用某种或某几种DRX配置。
一种方式是:
基站通过L3控制信息和/或L2控制信息半静态地将确定出的DRX配置信息指示给终端,即指示终端使用哪一种DRX配置信息;其中,L3可以是无线资源控制器(RRC,Radio Resource Control),L2可以是MAC控制单元(MAC CE,MAC Control Element);
或者,基站通过下行控制指示(DCI,Downlink Control Indication)信息动态地将确定出的DRX配置信息指示给终端;
或者,基站可以通过当前该终端正在进行的业务选择使用某种或某几种DRX配置信息。
或者,基站通过L3控制信息和/或L2控制信息将DRX配置索引发送给终端;相应地,终端存储有DRX配置索引与对应不同业务类型的DRX配置信息之间的映射关系,终端可以根据接收到的DRX配置索引使用对应的DRX的参数和定时器;
或者,基站通过DCI信息动态地将DRX配置索引发送给终端;相应地,终端存储有DRX配置索引与对应不同业务类型的DRX配置信息之间的映射关系,终端可以根据接收到的DRX配置索引使用对应的DRX的参数和定时器;
另一种方式是:
基站半静态和/或动态地同时将多套DRX配置信息发送给终端;相应地,终端根据不同的无线承载和/或逻辑信道和/或物理层参数,或者物理信道和/或RNTI,确定并使用相应的DRX配置信息。
较佳地,当DRX配置信息包括两套或两套以上时,基站只将其中DRX周期最小的DRX配置信息发送给终端。本公开的这种处理方式,对于终端同时进行多个业务,并且业务类型变化比较快时,直接采用多套DRX配置信息中DRX周期最小的DRX配置信息,减少了实现的复杂度。
在一实施例中,本公开方法还包括:
终端向基站反馈接收确认消息。
接收确认消息携带有用于指示是否成功接收到DRX配置信息的接收状态指示。当接收状态指示未成功接收到DRX配置信息,那么,基站需要重传DRX配置信息。
在一实施例中,本公开方法还包括:
当业务类型和/或逻辑信道和/或无线承载和/或物理层参数改变时,触发更新DRX配置信息。在一实施例中,还包括:触发DRX配置信息发送给终端。
本公开提供的技术方案是根据不同的业务类型来选择DRX的参数和定时器配置终端,实现了针对多种业务类型对终端进行灵活的DRX配置,在保证了终端节电的同时,也很好地适应了不同业务特征的传输时延要求,从而适应未来移动通信技术的要求。
