Description

数据重传处理方法及装置 技术领域
本发明涉及智能交通技术领域，具体而言，涉及一种数据重传处理方法及装置。
背景技术
长期演进(Long Term Evolution，简称为LTE)***中，为了终端的节电考虑，采用了非连续接收(Discontinuous Reception，简称为DRX)技术，终端可以根据配置周期性的进行物理下行控制信道(Physical Downlink Control Channel，简称为PDCCH)信道的监听。对于某些特定的过程，比如收到新传的调度后、下行重传、上行重传、非竞争随机接入下行数据等待、冲突解决过程、调度请求(Scheduling Request，简称为SR)过程等等，在这些特定的过程之后进行监听，终端可能需要在DRX周期外持续检测PDCCH一段时间，为此定义了一个DRX的激活时间(active time)，即处于监听状态，终端在激活时间内，没有特殊情况的都需要检测PDCCH，相对于之前一直处于监听状态的方案，达到了省电的效果。
LTE***中，目前采用的是同步发送的方法，图1是根据相关技术中终端发送上行数据过程的示意图，如图1所示，终端在T1时刻收到基站的上行调度指示，在4个子帧后就是T2时刻，在上行调度中指示的资源上发送上行数据，在4个子帧后就是T3时刻才进入监听状态，监听是否需要重传，即监听基站新的上行调度指示，或者监听基站的反馈，T3时刻，如果终端配置了DRX，需要进入激活时间状态。如果收到基站的NACK，则会在4个子帧后，就是T4时刻，重发上行数据。这几个时间之间的间隔是固定的4个子帧，特别是T2时刻和T3时刻之间是4个子帧，称为同步发送。
随着数据业务的快速增长，在不久的将来，授权频谱将不能承受如此巨大的数据量；所以LTE运营商考虑在非授权频谱资源(Unlicensed Carrier)中部署LTE，通过非授权频谱来分担授权载波中的数据流量。非授权载波(免授权频谱)是指在满足有关规定(无线电管制)下，不需要授权就能直接使用的频谱(或载波)。例如，微波炉、遥控玩具飞机、无线鼠标、无线键盘、高保真无线上网(Wireless Fidelity，简称为WiFi)等都使用了非授权载波。在有的情况下，非授权载波需要通过竞争才能使用。如果基站(包括WiFi接入点)没有竞争到资源，则不能使用非授权载波。非授权载波和授权载波可以通过载波聚合的方式使用，也可以通过双连接的方式使用，非授权载波一般作为数据传输的补充，即授权载波作为主服务小区(Primary Cell，简称为Pcell)，非授权载波作为辅服务小区(Secondary Cell，简称为Scell)。
非授权载波的可用资源是不连续的，而且不可控的，如图1所示，假如T4时刻没有资源可以使用，则数据的重发需要再等待8个子帧，时延不可控制，为此引入异步发送的方法，即，基站不需要限定在T3时刻给终端重传调度，如果可能的话，可以提前或者推后，这样，可以最大程度地根据资源来调度发送上行数据。但是由此引入其他问题，终端为了监听基站可能的重传调度，需要提前进入DRX的激活状态，但是相关技术中并没有一种机制确保在合 适的时机进入监听，这样可能会在提前很长时间进行监听状态，使得耗电增加，用户体验变差。
针对相关技术中为了监听可能的重传调度没有一种机制确保在合适的时机进入监听状态，导致耗电增加的问题，还未提出有效的解决方案。

步骤S202，在发送上行数据或接收到调度指令，等待预定个数的子帧之后，进入监听状态；
步骤S204，监听重传调度指令；
步骤S206，在监听到该重传调度指令之后，进行数据重传处理。
通过上述步骤，在发送上行数据或接收到调度指令，等待预定个数的子帧之后，进入监听状态；监听重传调度指令；在监听到该重传调度指令之后，进行数据重传处理，解决了相关技术中为了监听可能的重传调度没有一种机制确保在合适的时机进入监听状态，导致耗电增加的问题，减少了耗电，提高了用户体验度。
在一个可选的实施例中，在发送上行数据或接收到调度指令，等待预定个数的子帧之后，进入监听状态可以包括：接收该调度指令，并解析该调度命令中的上行时频域资源；在该时频域资源上发送数据，进入非连续接收DRX的激活状态或者延续DRX的激活状态；在所述时频域资源上发送数据，等待预定个数的子帧之后，进入非连续接收DRX的激活状态或者延续DRX的激活状态；或者，在接收所述调度指令，等待预定个数的子帧之后，进入非连续接收DRX的激活状态或者延续DRX的激活状态。
进一步地，在开始监听重传调度指令时启动定时器，其中，该定时器用于设置监听重传调度指令的时间，该定时器的长度可以为5个子帧。
在另一个可选的实施例中，在监听到该重传调度指令之后，进行数据重传处理可以包括：接收重传调度指令，并解析该重传调度指令中的上行时频域资源；停止该定时器；在预定个数的子帧后，在该时频域资源上进行数据重传。
为了保证数据成功重传，在数据重传失败的情况下，在等待预定个数的子帧之后，进入监听状态。
上述的预定个数的子帧为默认子帧数或所述调度指令中指示的等待开始监听调度的子帧数，或终端收到上行调度到发送上行数据的时间间隔子帧数。
本发明实施例还提供了一种数据重传处理装置，图3是根据本发明实施例的一种数据重传处理装置的框图，如图3所示，包括：

进入状态单元44，设置为在该时频域资源上发送数据，进入非连续接收DRX的激活状态或者延续DRX的激活状态；在所述时频域资源上发送数据，等待预定个数的子帧之后，进入非连续接收DRX的激活状态或者延续DRX的激活状态；或者，在接收所述调度指令，等待预定个数的子帧之后，进入非连续接收DRX的激活状态或者延续DRX的激活状态。
图5是根据本发明优选实施例的一种数据重传处理装置的框图二，如图5所示，该装置还包括：
启动模块52，设置为在开始监听重传调度指令时启动定时器，其中，该定时器用于设置监听重传调度指令的时间，该定时器的长度为5个子帧。

解析单元62，设置为接收重传调度指令，并解析该重传调度指令中的上行时频域资源；
停止单元64，设置为停止该定时器；
数据重传单元66，设置为在预定个数的子帧后，在该时频域资源上进行数据重传。
下面结合具体实施例对本发明实施例进行进一步说明。
对于非授权载波，终端进入DRX激活状态的时间，可以是以下情况中的一种：
1)终端发送上行数据后，等待n个子帧后，进入DRX激活状态。
2)终端收到上行调度后，等待n个子帧后，进入DRX激活状态。
3)终端发送上行数据，进入DRX的激活状态。
其中，监听的时间长度可以通过定时器设定。n个子帧，是指定个数的子帧，可以是固定一个默认的值比如4，也可以基站配置，也可以在调度命令中指示，也可以是终端收到上行调度到发送上行数据的时间间隔用子帧来表示。
以下实施例中，基站有3个小区，小区1是授权载波，小区3和小区4是非授权载波。
实施例一
图7是根据本发明实施例的数据重传的示意图，如图7所示，终端与小区1建立了连接，小区1就是主服务小区，包括：
步骤一，由于业务量增加，基站1根据测量报告，给终端增加小区3，小区3为非授权载波，需要通过竞争方式来获取资源使用权限，小区3是辅服务小区；
步骤二，终端收到小区3的配置信息，增加小区3；
步骤三，基站根据终端业务量的需求，发起小区3的资源竞争过程；
步骤四，基站竞争到小区3的资源后，开始调度终端在小区3进行数据发送和接收；
步骤五，终端在T1时刻收到小区3的调度，并解析调度命令中的上行时频域资源，在指定个数的子帧如默认3个子帧，T2时刻在上述时频域资源上发送上行数据，开始进入DRX的激活状态或者延续DRX的激活状态，启动上行重传等待定时器，长度为6个子帧，上述默认3各子帧也可以是默认4个子帧或者调度命令中指示的2个子帧。
步骤六，终端在5个子帧后即T3时刻收到小区3的调度，并解析调度命令中的上行时频域资源，和相关指示，获知需要进行上行重传，停止上行重传定时器，在指定个数的子帧如默认3个子帧，T4时刻在上述时频域资源上发送上行数据，开始进入DRX的激活状态或者延续DRX的激活状态，启动上行重传等待定时器，长度为6个子帧，终端在T3时刻，解析调度命令发现是新传，终端的行为是一样的。
实施例二
图8是根据本发明优选实施例的数据重传的示意图，如图8所示，终端与小区1建立了连接，小区1就是主服务小区，包括：
步骤一，由于业务量增加，基站1根据测量报告，给终端增加小区3，小区3为非授权载波，需要通过竞争方式来获取资源使用权限，小区3是辅服务小区；
步骤二，终端收到小区3的配置信息，增加小区3；
步骤三，基站根据终端业务量的需求，发起小区3的资源竞争过程；
步骤四，基站竞争到小区3的资源后，开始调度终端在小区3进行数据发送和接收；
步骤五，终端在T1时刻收到小区3的调度，并解析调度命令中的上行时频域资源，在指定个数的子帧如调度命令中指示的2个子帧后，T2时刻在上述时频域资源上发送上行数据，等待指定个数的子帧如默认的3个子帧后，T3时刻开始进入DRX的激活状态或者延续DRX的激活状态，启动上行重传等待定时器，长度为5个子帧，上述3个子帧可以是，终端通过调度命令中指示获得的3个子帧。
本发明实施例中，终端收到调度命令的时刻T1，到发送上行数据的时刻T2，之间的时间间隔是调度命令中指示的2个子帧，那么，终端可以在发送上行数据T2时刻等待2个子帧(是终端收到调度命令的时刻T1，到发送上行数据的时刻T2，之间的时间间隔是调度命令中指示的2个子帧)后，开始进入DRX的激活状态或者延续DRX的激活状态。
步骤六，终端在5个子帧后即T4时刻收到小区3的调度，并解析调度命令中的上行时频域资源，和相关指示，获知需要进行上行重传，停止上行重传定时器，在指定个数的子帧如调度命令中指示的2个子帧后，T5时刻在上述时频域资源上发送上行数据，等待指定个数的 子帧如默认3个子帧后，T6时刻开始进入DRX的激活状态或者延续DRX的激活状态，启动上行重传等待定时器，长度为5个子帧。
终端在T4时刻，解析调度命令发现是新传，终端的行为是一样的。
终端在上行重传定时器超时之前，获知竞争到的小区3上的资源使用结束，则停止定时器，终端也就进入DRX的去激活状态。
通过上述的方法，可以使得终端在非授权载波上灵活地重发上行数据，并且节约电能。
