为使本公开实施例的目的、技术方案和优点更加清楚,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,所描述的实施例仅仅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。
图1是本公开实施例提供的动态数据传输方法的流程示意图之一,如图1所示,本公开实施例提供一种动态数据传输方法,其执行主体可以为网络侧设备,例如,基站等。该方法包括:
步骤101、为终端配置SPS相关联的动态资源指示信息。
具体地,网络侧设备首先为终端配置SPS相关联的动态资源指示信息。
终端确定网络侧设备发送的SPS相关联的动态资源指示信息。
对于动态资源指示信息,可以是下行控制信息(Downlink Control Information,DCI)信令与SPS相关联,也可以是DCI携带的资源信息(例如,PDSCH资源)与SPS相关联。与SPS相关联的动态资源指示信息可以是一个或多个。本公开实施例以一个为例进行说明,多个的情况与之类似,此处不再赘述。
可选地,该动态资源指示信息是SPS相关联的DCI信令,通过DCI信令携带资源分配信息。
可选地,该方法还包括:

可选地,该监听位置信息包括以下信息中的一种或多种:

监听起始时间还包括以下信息中的一种或多种:
(1)与SPS相关联的时间点。
(2)独立的时间点。
2、网络侧设备为终端配置该DCI信令的监听窗口。
网络侧设备为终端配置该DCI信令的监听窗口的具体方法包括:
(1)网络侧设备为终端配置该DCI信令的监听窗口的监听起始时间以及持续时间。
监听起始时间还包括以下信息中的一种或多种:
i.与SPS相关联的时间点。
ii.独立的时间点。
该DCI信令的监听窗口的持续时间可以通过显性方式指示,也 可以通过隐形方式指示。
通过显性方式指示的方式包括以下中的一种或多种:
通过L1信令携带该DCI信令的监听窗口的持续时间;
通过媒体访问控制(Media Access Control,MAC)层信令携带该DCI信令的监听窗口的持续时间;
通过高层信令携带该DCI信令的监听窗口的持续时间。
通过隐性方式指示的方式包括通过为终端配置一个监听定时器,供终端根据该监听定时器确定该DCI信令的监听窗口的持续时间。
(2)网络侧设备为终端配置该DCI信令的监听窗口的监听起始时间以及监听终止时间。
监听起始时间和/或监听终止时间还包括以下信息中的一种或多种:
i.与SPS相关联的时间点。
ii.独立的时间点。
可选地,该监听位置信息还包括以下信息中的一种或多种:
1、与SPS相关联的时间点。
其中,与SPS相关联的时间点可以理解为一个相对时间点。
可选地,与SPS相关联的时间点为以下时间点中的一种或多种:
(1)与SPS PDSCH相关联的时间点。
具体地,与SPS相关联的时间点可以为与SPS PDSCH的起始时隙/终止时隙/起始符号/终止符号相关联的时间点。
图2是本公开实施例提供的SPS PDSCH增强方案示意图之一,如图2所示,例如,在SPS PDSCH的起始时隙之后的某一时间偏移量(offset),开始监听该DCI信令。
(2)与SPS PDSCH的混合自动重传请求肯定应答(Hybrid Automatic Repeat reQuest Acknowledgement,HARQ-ACK)相关联的时间点。
具体地,与SPS PDSCH的HARQ-ACK相关联的时间点可以为与SPS PDSCH的起始时隙/终止时隙/起始符号/终止符号相关联的时间点。
如图2所示,例如,在SPS PDSCH的HARQ-ACK的终止时隙之后的某一时间offset,开始监听该DCI信令。
(3)与SPS PDSCH的往返时间(Round Trip Time,RTT)定时器超时相关联的时间点。
具体地,与SPS PDSCH的RTT定时器超时相关联的时间点可以为与SPS PDSCH的RTT定时器超时的起始时隙/终止时隙/起始符号/终止符号相关联的时间点。
如图2所示,例如,在SPS PDSCH的RTT定时器超时的起始符号之后的某一时间offset,开始监听该DCI信令。
可选地,监听位置信息相对于该时间点的偏移值的时间单位为时隙、跨度(span)、符号或毫秒。
具体地,可以配置与上述时间点之间的时间offset,时间单位可以是ms,也可以是时隙,也可以是符号。
例如:起始时间的具体单位可以是时隙的起始符号,或一个时隙的某个符号位置。监听窗口的持续时间可以是连续的几个时隙,也可以是某个时隙的连续几个符号,也可以是连续几个时隙中固定几个符号。定时器长度单位可以是ms,也可以是时隙,也可以是符号。
需要说明的是:起始时间可以与SPS PDSCH或SPS PDSCH的HARQ-ACK或SPS PDSCH的RTT定时器超时等的起始时隙/终止时隙/起始符号/终止符号相关联的时间点之间的时间offset,可以是大于等于0的数值,即,以上述时间点为起始时间,或在上述时间点之后的offset时间位置;也可以是小于0的数值,即,距离上述时间点之前的offset时间位置。
或者,起始时间可以与SPS PDSCH或SPS PDSCH的 HARQ-ACK或SPS PDSCH的RTT定时器超时等的起始时隙/终止时隙/起始符号/终止符号相关联的时间点之间的时间offset,是大于等于0的数值,但起始时间点可以是以上述时间点为起始时间,或在上述时间点之后的offset时间位置,或距离上述时间点之前的offset时间位置。
2、独立的时间点。
独立的时间点可以理解为一个具体的时间点,或者,终端通过计算确定的一个具体的时间点。该独立的时间点可以与SPS无关。
例如,起始时间可以是绝对时间,通过配置周期(periodicity)与offset,终端根据***帧号(System Frame Number,SFN)进行计算得到的具体时间。
例如,起始时间的时隙号满足以下条件:
二、根据第一信息进行动态调整的监听位置信息。
基站为终端配置第一信息,用于动态指示监听位置信息的变化,例如:动态指示监听窗口的大小,监听起始位置,监听终止位置中的一个或多个。
例如,指示终端在监听到动态调度DCI之后继续监听的时间。
第一信息可以通过L1信令、MAC信令或高层信令携带。
例如,第一信息可以是监听计时器或持续时间,也可以是指示信令信息,也可以参考信号。以监听计时器为例,当监听计时器未超时时,终端可以继续进行业务专属DCI监听。当业务数据包因时延抖动而在监听窗口结束时进行数据传输时,由于后续没有监听机会而导致数据包需要等下一个监听窗口或监听机会才能传输,配置监听计时器有利于减小因时延抖动而引起的传输时延。
可选地,DCI信令的监听时机(Monitoring Occasion,MO)可以是以下几种中一种:
(1)可以通过现有的搜索空间集的配置方式进行配置.
例如,配置监听周期及偏移量、频域聚合等级(Aggregation Level,AL)等级等参数。
(2)也可以配置单个MO上的相关配置(这里可以是时隙级,也可以是span级)。
(3)也可以关联搜索空间的索引值。
可选地,对于DCI信令的MO的时间单位可以是时隙,也可以是span,也可以通过关联搜索空间的索引值进行监听机会配置。
步骤102、在非连续接收(Discontinuous Reception,DRX)的非激活期内利用该动态资源指示信息进行动态数据传输指示。
具体地,网络侧设备在为终端配置SPS相关联的动态资源指示信息之后,网络侧设备在DRX-off内利用该动态资源指示信息进行动态数据传输指示。
终端在确定网络侧设备发送的SPS相关联的动态资源指示信息之后,在DRX-off内根据该动态资源指示信息进行动态数据接收。
可选地,还包括:
网络侧设备向终端发送动态传输指示,该动态传输指示用于指示终端进行动态数据传输。
基站指示终端进行后续动态传输指示,表示终端可以在SPS PDSCH接收后进行动态调度DCI的监听行为;否则,终端进行常规的SPS PDSCH接收。
可选地,动态传输指示通过L1信令、媒体访问控制控制单元(Media Access Control Control Element,MAC CE)信令、节能信号或高层信令指示。
例如,当终端接收到以下指示时,同时基站配置了动态调度DCI 的监听位置信息,表示终端可以在SPS PDSCH接收后进行动态调度DCI的监听行为;否则,终端进行常规的SPS PDSCH接收。具体的指示有以下一种或几种组合:
1、终端能力支持SPS PDSCH接收后进行动态调度DCI的监听行为。
2、通过调度DCI(如:SPS PDSCH激活DCI、SPS PDSCH重传DCI等)进行指示。
3、通过MAC CE指示终端可以在后续的SPS PDSCH接收后进行动态调度DCI的监听行为。
4、高层信令配置了开关,表示可以支持SPS PDSCH接收后进行动态调度DCI的监听行为。
5、通过节能信号指示在后续的SPS PDSCH接收后进行动态调度DCI的监听行为。
需要说明的是:对于几种指示的组合是指同时存在上述指示的几种,例如:终端能力以及调度DCI指示,或终端能力及高层信令配置的开关等,此处不再赘述。
可选地,如果SPS PDSCH没有完成网络侧设备侧缓冲区的数据传输,则网络侧设备会指示终端进行SPS PDSCH后的动态调度DCI检测。
当终端在接收到网络侧设备发送的动态传输指示之后,终端从网络侧设备配置的监听起始位置开始,持续进行动态调度DCI监听,监听的粒度是MO。即在DRX-off内根据该动态资源指示信息进行动态数据接收。
本公开实施例提供的动态数据传输方法,在DRX-off内通过动态调度辅助SPS PDSCH传输,完成数据大小相差较大的数据业务传输,在数据包较大,但预留的SPS PDSCH资源不足的情况下辅助传输数据包,而不需要等待下一个SPS PDSCH或DRX激活期,在数据包 较小时,利用预留SPS PDSCH资源的周期性以及动态调度资源可以完成数据传输,从而降低了传输时延。
可选地,还包括:
向终端发送停止指示,该停止指示用于指示终端停止动态数据传输。
具体地,终端在特定条件满足时或基站发送指示,令终端在动态调度DCI的监听窗口中停止监听DCI。
例如,当终端完成数据包传输时,为了避免不必要的DCI监听,基站侧指示终端在动态调度DCI的监听窗口中停止监听DCI。
可选地,该停止指示通过L1信令、媒体访问控制控制单元MAC CE信令、节能信号或高层信令承载。
图3是本公开实施例提供的SPS PDSCH增强方案示意图之二,如图3所示,例如,终端在特定条件满足或基站发送停止指示时,令终端在动态调度DCI的监听窗口中停止监听DCI,具体可以是以下几种条件的一种或几种组合:
1、终端接收到调度信息为空的(dummy)调度DCI。
2、终端基于已经配置的定时器超时,这里定时器与监听窗口是相互独立的定时器。
3、终端接收到SPS PDSCH释放DCI。
需要说明的是:这里的几种组合是指上述几种指示同时存在,满足任一个即可停止监听动态调度DCI。
例如:监听定时器以及调度信息为空的调度DCI同时配置时,任一个满足条件即可停止监听动态调度DCI等,此处不再赘述。
本公开实施例中,停止监听DCI可以表示终端跳过监听,或者终端进入休眠。
本公开实施例提供的动态数据传输方法,在满足特定的条件是时,停止监听动态调度DCI,还可以降低信令的开销,提高频谱利用率。
可选地,还可以通过节能信号,如DCI格式2_6或非调度DCI或MAC CE携带了动态调度DCI的监听窗口和/或监听起始位置。
图4是本公开实施例提供的SPS PDSCH增强方案示意图之三,如图4,对于DCI格式2_6携带动态调度DCI的监听窗口和/或监听起始位置的情况,是指在DRX非激活期可以配置一个或多个监听机会,用于指示后续一个或多个SPS PDSCH后是否要进行动态调度DCI的监听。DCI格式2_6的监听位置可以在SPS PDSCH之后发送。
可选地,以起始时间在参考时间点之前为例,如果终端在SPS PDSCH之前监测到动态调度DCI,则终端可以执行以下行为之一:
1、如果动态调度DCI指示的PDSCH位于SPS PDSCH之后,则终端可以在SPS PDSCH或SPS PDSCH的HARQ-ACK或SPS PDSCH的RTT定时器超时之后,根据动态调度DCI指示的PDSCH接收动态调度的数据信息。
2、如果动态调度DCI指示的PDSCH位于SPS PDSCH之前,或与SPS PDSCH时隙重叠,终端可以根据动态调度DCI指示的PDSCH接收动态调度的数据信息,而不进行SPS PDSCH的接收,也可以在SPS PDSCH的基础上接收不重叠的PDSCH。
上述参考时间点可以是SPS PDSCH或SPS PDSCH的HARQ-ACK或SPS PDSCH的RTT定时器超时等的起始时隙/终止时隙/起始符号/终止符号相关联的时间点。
