Description

数据传输方法、装置、终端及存储介质 技术领域
本申请涉及通信技术领域,尤其涉及一种数据传输方法、装置、终端及存储介质。
背景技术
随着通信技术领域的高速发展,蜂窝网络中,终端和终端之间可以直接通信,终端和终端之间的链路称为侧行链路(sidelink,SL)。在无线通信网络中,由于终端通常是使用电池的,为了延长电池的使用时间,避免频繁换电池或者充电,出于节能的目的,需要在侧行链路中引入DRX机制。
终端和终端之间通过SL传输数据,出于节能的考虑,作为数据的接受方,终端只在部分时段才需要监听,而不需要连续不断的进行监听。此外,对于SL上存在的两种数据传输模式:组播和广播,DRX配置信息目前是有两种获取方式,一种是当终端位于基站覆盖范围内时,通过驻留小区或者服务小区获得DRX配置信息,另一种是当终端位于基站覆盖范围外时,终端使用预配置的DRX配置信息。
目前,由于组播和广播的终端之间并不进行连接建立,也不交互配置,那么当有的终端位于覆盖范围内,有的终端位于覆盖范围外时,可能他们获得的DRX配置信息并不相同,导致双方可能无法进行通信。

下面结合图2A对本申请实施例中的一种数据传输方法进行说明,图2A为本申请实施例提供的一种数据传输方法的流程示意图,方法具体包括以下步骤S101~S104。
S101,第一终端获取第一非连续接收DRX配置信息。
其中,所述第一DRX配置信息为第一小区提供的信息,所述第一小区为所述第一终端的服务小区或者驻留小区。
此外,第一DRX配置信息为当第一终端位于基站覆盖范围内时,通过所述小区的系统信息获得的DRX配置信息。
需要说明的是,本申请实施例考虑当第一终端位于基站覆盖范围内时,由第一终端的服务小区或者驻留小区通过系统信息向第一终端提供第一DRX配置信息以实现对第一终端的DRX配置信息的配置。
进一步的,系统信息可以包括系统信息块(system information block,SIB)信息。
S102,所述第一终端获取第二DRX配置信息。
其中,所述第二DRX配置信息为预先配置在所述第一终端中的信息,所述第一DRX配置信息和所述第二DRX配置信息不同。
此外,所述第二DRX配置信息为所述第一终端位于基站覆盖范围外时,终端使用的DRX配置信息。
需要说明的是,本申请实施例考虑由服务方根据需要在预先在所述第一终端中配置所述第二DRX配置信息,且对所述第二DRX配置信息不做具体限定。
S103,若所述第一小区的参考信号接收功率RSRP小于RSRP阈值,则所述第一终端根据所述第一DRX配置信息和所述第二DRX配置信息确定第三DRX配置信息。
其中,对所述RSRP阈值不做具体限定,用户可以根据实际需要对RSRP阈值进行设置。
具体实现中,当所述第一小区的参考RSRP小于RSRP阈值时,该第一终端处于所属第一小区的边缘,因此,在该第一终端的周围可能存在位于基站覆盖范围外的、使用所述第二DRX配置信息的其他终端。
可见,本示例中,通过在终端第一小区的参考RSRP小于RSRP阈值时,采用该小区提供的DRX配置信息和预先配置在第一终端中的DRX配置信息共同确定的DRX配置信息,保证在组播或者广播的方式下,该终端和其他终端之间侧行链路的DRX配置信息的一致性。
S104,所述第一终端根据所述第三DRX配置信息进行数据传输。
其中,所述第一终端根据所述第三DRX配置信息进行数据传输可以是:所述第一终端根据所述第三DRX配置信息发送数据,和/或,所述第一终端根据所述第三DRX配置信息接收数据。
可见,本示例中,第一终端通过小区提供的DRX配置信息和预先配置在第一终端中的DRX配置信息共同确定的DRX配置信息,使得该终端能够和 其他终端进行数据传输。
在一个可能的示例中,所述方法还包括:若所述参考RSRP大于或者等于所述RSRP阈值,则所述第一终端根据所述第一DRX配置信息进行数据传输。
参考RSRP大于或者等于所述RSRP阈值,即是,终端处于基站覆盖范围内且距离小区边缘较远时,此时,该终端周围不存在位于覆盖范围外的、使用第二DRX配置信息的其他终端,因此,该终端可以直接使用,该终端的服务小区或者驻留小区,提供的DRX配置信息进行数据传输。
其中,所述第一DRX配置信息包括第一周期启动位置、第一激活偏移、第一DRX周期、第一激活定时器、第一DRX静止定时器、第一混合自动重传请求往返时延HARQ RTT定时器以及第一DRX重传定时器中的至少一种;所述第二DRX配置信息包括第二周期启动位置、第二激活偏移、第二DRX周期、第二激活定时器、第二DRX静止定时器、第二HARQ RTT定时器以及第二DRX重传定时器中的至少一种。
周期启动位置(drx-StartOffset)是指DRX周期起始的位置,通常单位为子帧(subframe)。
激活偏移(drx-Slot Offset)是指启动激活定时器需推迟的时间长度,通常单位为时隙(slot)。
DRX周期(drx-Long Cycle或者drx-Short Cycle)是指主要是配置的DRX的周期,包括需要监控的时间段和,有可能进入DRX的时间段。
激活定时器(drx-onDuration Timer)确定DRX周期开始需持续监控的时间段。
DRX静止定时器(drx-Inactivity Timer)确定在指示新传的控制信令之后需持续监听的时间段。
混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)往返时延(Round Trip Time,RTT)定时器(drx-HARQ-RTT-Timer)是指到进行SL的HARQ重传之前的最小需等待的时间段。
DRX重传定时器(drx-Retransmission Timer)确定终端在SL的HARQ重传前最长需监控的时间段。
下面,以第一终端的服务小区或者驻留小区的参考RSRP小于RSRP阈值为前提,对本申请实施例涉及的不同场景下多种第三DRX配置信息中各种参数的确定方式进行详细说明。
首先,针对第一终端为数据发送方的场景进行说明。
对于第三DRX配置信息中的激活时间,所述第一终端根据所述第一DRX配置信息和第二DRX配置信息确定第三DRX配置信息,包括:所述第一终端根据所述第一周期启动位置、所述第一激活偏移、所述第一DRX周期和所 述第一激活定时器确定第一激活时间;所述第一终端根据所述第二周期启动位置、第二激活偏移、所述第二DRX周期和所述第二激活定时器确定第二激活时间;所述第一终端确定所述第一激活时间和所述第二激活时间的交集为第一目标激活时间;所述第一终端确定所述第三DRX配置信息包括所述第一目标激活时间。
第一激活时间通过如下方式确定:
若当前子帧号满足[(系统帧号×10)+子帧号]modulo第一DRX周期=第一周期起始位置,其中modulo为取模运算,则在该子帧起始位置推迟第一激活偏移后,启动第一激活定时器,第一激活时间为第一激活定时器运行的时间。
第二激活时间通过如下方式确定:
若当前子帧号满足[(系统帧号×10)+子帧号]modulo第二DRX周期=第二周期起始位置,其中modulo为取模运算,则在该子帧起始位置推迟第二激活偏移后,启动第二激活定时器,第二激活时间为第二激活定时器运行的时间。
第一终端采用上述方式确定出第一激活时间和第二激活时间后,再确定第一激活时间和第二激活时间的交集,将该交集作为所述第一目标激活时间,并确定第三DRX配置信息包括所述第一目标激活时间。
示例性的,请参见图2B。如第一DRX配置信息中的第一激活时间配置,若第一DRX配置信息包括第一周期起始位置A1-1(图中未示出)、第一激活偏移A1-2(图中未示出)、第一DRX周期B1和第一激活定时器C1,则第一终端能够确定出该第一DRX周期B1的第一激活停止位置D1,从第一激活定时器启动时刻A1(由第一周期起始位置A1-1、第一激活偏移A1-2共同确定)到D1的时间即是第一激活时间。如第二DRX配置信息中的第二激活时间配置,若第二DRX配置信息包括第二周期起始位置A2-1、第二激活偏移A2-2、第二DRX周期B2和第二激活定时器C2,则第一终端能够确定出该第二DRX周期B2的第二激活停止位置D2,从第二激活定时器启动时刻A2(由第二周期起始位置A2-1、第二激活偏移A2-2共同确定)到D2的时间即是第二激活时间。第一终端作为数据发送方时,其确定出的第三DRX配置信息中的第一激活时间,为A1到D1的时间以及A2到D2的时间的交集,如图示出的A2到D1的时间即是所述第一目标激活时间,最终确定第三DRX配置信息包括A2到D1的时间。
对于第三DRX配置信息中的DRX静止定时器,所述第一终端根据所述第一DRX配置信息和第二DRX配置信息确定第三DRX配置信息的实现方式为:所述第一终端将所述第一DRX静止定时器和所述第二DRX静止定时器比较,确定所述第一DRX静止定时器和所述第二DRX静止定时器中长度更小的DRX静止定时器为第一目标DRX静止定时器;所述第一终端确定所述第三DRX配置信息包括所述第一目标DRX静止定时器。
可见,第一终端在第一小区的参考RSRP小于RSRP阈值的情况下,采用所述第一小区提供的DRX静止定时器和预先配置在该第一终端中的DRX静止定时器中,长度更小的DRX静止定时器发送数据。
对于第三DRX配置信息中的HARQ RTT定时器,所述第一终端根据所述第一DRX配置信息和第二DRX配置信息确定第三DRX配置信息的实现方式为:
所述第一终端将所述第一HARQ RTT定时器和所述第二HARQ RTT定时器进行比较,得到所述第一HARQ RTT定时器和所述第二HARQ RTT定时器中长度更大的HARQ RTT定时器为第一目标HARQ RTT定时器;所述第一终端确定所述第三DRX配置信息包括所述第一目标HARQ RTT定时器。
具体实现中,第一终端在第一小区的参考RSRP小于RSRP阈值的情况下,采用所述第一小区提供的HARQ RTT定时器和预先配置在第一终端中的HARQ RTT定时器中,长度更大的HARQ RTT定时器发送数据。
示例性的,请参见图2C,E为HARQ RTT定时器的启动位置。如第一DRX配置信息中的配置,G1为第一DRX重传定时器的启动位置,E到G1之间的时间的长度为第一HARQ RTT定时器F1的长度。如第二DRX配置信息中的配置,G2为第二DRX重传定时器的启动位置,E到G2之间的时间的长度为第二HARQ RTT定时器F2的长度。因为F1的长度大于F2的长度,因此,如第一终端作为数据发送方时,第三DRX配置信息中的配置,采用长度更大的F1为第一目标HARQ RTT定时器,即是,第一目标HARQ RTT定时器为F1。
对于第三DRX配置信息中的DRX重传定时器,所述第一终端根据所述第一DRX配置信息和第二DRX配置信息确定第三DRX配置信息的实现方式可以是:所述第一终端获取所述第一DRX重传定时器和所述第一HARQ RTT定时器的第一和值;所述第一终端获取所述第二DRX重传定时器和所述第二HARQ RTT定时器的第二和值;所述第一终端将所述第一和值和第二和值进行比较,确定所述第一和值和第二和值中更小的和值为第一目标和值;所述第一终端将所述第一目标和值减去所述第一目标HARQ RTT定时器,得到第一目标DRX重传定时器;所述第一终端确定所述第三DRX配置信息包括所述第一目标DRX重传定时器。
示例性的,请参见图2C,E为HARQ RTT定时器的启动位置。如第一DRX配置信息中的配置,G1为第一DRX重传定时器的启动位置,E到G1之间的时间的长度为第一HARQ RTT定时器F1的长度,第一DRX重传定时器为H1。如第二DRX配置信息中的配置,G2为第二DRX重传定时器的启动位置,E到G2之间的时间的长度为第二HARQ RTT定时器F2的长度,第二DRX重传定时器为H2。因为第一和值F1+H1大于第二和值F2+H2,F1 的长度大于F2的长度,因此,如第一终端作为数据发送方时,第三DRX配置信息中的配置,确定长度更长的F1作为第一目标HARQ RTT定时器,即是,第一目标HARQ RTT定时器的长度为F1,采用F1+H1和F2+H2中更小的第一目标和值F2+H2减去F1,得到第一目标DRX重传定时器H3,可以理解的是,此种情况下,第一终端采用G1为第一目标DRX重传定时器的启动位置。
作为一种可能的实现方式,所述第一终端根据所述第三DRX配置信息进行数据传输的实现方式为:所述第一终端根据所述第一目标激活时间、所述第一目标DRX静止定时器、所述第一目标HARQ RTT定时器以及所述第一目标DRX重传定时器中的至少一种发送数据。
其中,最优选的数据发送方式为第一终端根据第一目标激活时间、第一目标DRX静止定时器、第一目标HARQ RTT定时器以及第一目标DRX重传定时器发送数据。
接着,针对第一终端为数据接收方的场景进行说明。
对于第三DRX配置信息中的激活时间,所述第一终端根据所述第一DRX配置信息和第二DRX配置信息确定第三DRX配置信息的实现方式可以是:所述第一终端根据所述第一周期启动位置、所述第一激活偏移、所述第一DRX周期和所述第一激活定时器确定第一激活时间;所述第一终端根据所述第二周期启动位置、第二激活偏移、所述第二DRX周期和所述第二激活定时器确定第二激活时间;所述第一终端确定所述第一激活时间和所述第二激活时间的并集为第二目标激活时间;所述第一终端确定所述第三配置信息DRX配置信息包括所述第二目标激活时间。
第一激活时间通过如下方式确定:
若当前子帧号满足[(系统帧号×10)+子帧号]modulo第一DRX周期=第一周期起始位置,其中modulo为取模运算,则在该子帧起始位置推迟第一激活偏移后,启动第一激活定时器,第一激活时间为第一激活定时器运行的时间。
第二激活时间通过如下方式确定:
若当前子帧号满足[(系统帧号×10)+子帧号]modulo第二DRX周期=第二周期起始位置,其中modulo为取模运算,则在该子帧起始位置推迟第二激活偏移后,启动第二激活定时器,第二激活时间为第二激活定时器运行的时间。
第一终端采用上述方式确定出第一激活时间和第二激活时间后,再确定第一激活时间和第二激活时间的并集,将该并集作为第二目标激活时间,并确定第三DRX配置信息包括该第二目标激活时间。
示例性的,请参见图2D,如第一DRX配置信息中的第一激活时间配置,若第一DRX配置信息包括所述第一周期起始位置A1-1(图中未示出)、所述第一激活偏移A1-2(图中未示出)、所述第一DRX周期B1和所述第一激 活定时器C1,则第一终端能够确定出该第一DRX周期B1的第一激活停止位置D1,从第一激活定时器启动时刻A1(由第一周期起始位置A1-1、第一激活偏移A1-2共同确定)到D1的时间即是第一激活时间,第一激活时间的长度等于C1。第二DRX配置信息中的第二激活时间配置,若第二DRX配置信息包括所述第二周期起始位置A2-1、所述第二激活偏移A2-2、所述第二DRX周期B2和所述第二激活定时器C2,则第一终端能够确定出该第二DRX周期B2的第二激活停止位置D2,从第二激活定时器启动时刻A2(由第二周期起始位置A2-1、第二激活偏移A2-2共同确定)到D2的时间即是第二激活时间,此时,第二激活时间的长度等于C2的长度。第一终端作为数据接收方时,其确定出的第三DRX配置信息中的第一激活时间为A1到D1的时间以及A2到D2的时间的并集,如图示出的A1到D2的时间即是所述第二目标激活时间。
对于第三DRX配置信息中的DRX静止定时器,所述第一终端根据所述第一DRX配置信息和第二DRX配置信息确定第三DRX配置信息的实现方式为:所述第一终端将所述第一DRX静止定时器和所述第二DRX静止定时器比较,确定所述第一DRX静止定时器和所述第二DRX静止定时器中长度更大的DRX静止定时器为第二目标DRX静止定时器;所述第一终端确定所述第三DRX配置信息包括所述第二目标DRX静止定时器。
具体实现中,第一终端在第一小区的参考RSRP小于RSRP阈值的情况下,采用所述第一小区提供DRX静止定时器和预先配置在第一终端中的DRX静止定时器中,长度更大的DRX静止定时器接收数据。
对于第三DRX配置信息中的HARQ RTT定时器,所述第一终端根据所述第一DRX配置信息和第二DRX配置信息确定第三DRX配置信息的实现方式为:所述第一终端将所述第一HARQ RTT定时器和所述第二HARQ RTT定时器进行比较,得到所述第一HARQ RTT定时器和所述第二HARQ RTT定时器中长度更小的HARQ RTT定时器为第二目标HARQ RTT定时器;所述第一终端确定所述第三DRX配置信息包括所述第二目标HARQ RTT定时器。
具体实现中,第一终端在第一小区的参考RSRP小于RSRP阈值的情况下,采用所述第一小区提供的HARQ RTT定时器和预先配置在第一终端中的HARQ RTT定时器中,长度更小的HARQ RTT定时器接收数据。
示例性的,请参见图2E,图中,E为HARQ RTT定时器的启动位置。如第一DRX配置信息中的配置,G1为第一DRX重传定时器的启动位置,E到G1之间的时间的长度为第一HARQ RTT定时器F1的长度。如第二DRX配置信息中的配置,G2为第二DRX重传定时器的启动位置,E到G2之间的时间的长度为第二HARQ RTT定时器F2的长度。因为F2的长度小于F1的长度,因此,如第一终端作为数据接收方时,第三DRX配置信息中的配置,采用长度更小的F2作为第二目标HARQ RTT定时器,此种情况下,第二目标 HARQ RTT定时器的长度为F2。
对于第三DRX配置信息中的DRX重传定时器,所述第一终端根据所述第一DRX配置信息和第二DRX配置信息确定第三DRX配置信息的实现方式为:
所述第一终端获取所述第一DRX重传定时器和所述第一HARQ RTT定时器的第一和值;所述第一终端获取所述第二DRX重传定时器和所述第二HARQ RTT定时器的第二和值;所述第一终端将所述第一和值和第二和值进行比较,确定所述第一和值和第二和值中更大的和值为第二目标和值;所述第一终端将所述第二目标和值减去所述第二目标HARQ RTT定时器,得到第二目标DRX重传定时器;所述第一终端确定所述第三DRX配置信息包括所述第二目标DRX重传定时器。
示例性的,请参见图2E,图中,E为HARQ RTT定时器的启动位置。如第一DRX配置信息中的配置,G1为第一DRX重传定时器的启动位置,E到G1之间的时间的长度为第一HARQ RTT定时器F1的长度,第一DRX重传定时器为H1。如第二DRX配置信息中的配置,G2为第二DRX重传定时器的启动位置,E到G2之间的时间的长度为第二HARQ RTT定时器F2的长度,第二DRX重传定时器为H2。因为第一和值F1+H1大于第二和值F2+H2,第二目标HARQ RTT定时器为F2,因此,如第一终端作为数据接收方时,第三DRX配置信息中的配置,采用F1+H1和F2+H2中更大的第二目标和值F1+H1减去F2的长度,得到第二目标DRX重传定时器H4,可以理解的是,此种情况下,第一终端采用G2为第二目标DRX重传定时器的启动位置。
作为一种可能的实现方式,所述第一终端根据所述第三DRX配置信息进行数据传输,包括:所述第一终端所述第二目标激活时间、所述第二目标DRX静止定时器、所述第二目标HARQ RTT定时器以及所述第二目标DRX重传定时器中的至少一种接收数据。
其中,最优选的数据接收方式为第一终端根据第二目标激活时间、第二目标DRX静止定时器、第二目标HARQ RTT定时器以及第二目标DRX重传定时器接收数据。
