具体实施方式
图1为本申请的应用场景示意图,该场景中包括终端设备和网络设备,其中,网络设备可以是基站。
现有基于免调度指令的上行数据传输中,发送上行数据的资源单元与接收上行数据的反馈信息的资源单元具有固定的时序关系,如图2所示,图2为现有技术的上行数据发送示意图;假设固定的时序关系为间隔4个时间单元,若发送上行数据的资源单元对应的时间单元为0,则接收上行数据的反馈信息的资源单元对应的时间单元为4。若发送上行数据的资源单元对应的时间单元为1,则接收上行数据的反馈信息的资源单元对应的时间单元为5,依次类推。上行数据的反馈信息的接收时序与发送上行数据的时序一致。然而,由于每个时间单元发送的数据包的大小不一,例如:0号时间单元发送的数据包远大于1号时间单元发送的数据包2的大小,网络设备解析完数据包2的时间早于解析完数据包1的时间,但由于接收数据包1的反馈信息在时间单元4,接收数据包2的反馈信息在时间单元5,因此,需要等待数据包1解析完,先发数据包1的反馈信息之后,才能发数据包2的反馈信息,因此,造成上行数据发送的时延较大。
本申请为了降低数据发送的时延,通过网络设备为终端设备配置时间窗,以及时间窗的时间单元与发送数据的时间单元之间的时序关系,时间窗包含至少两个时间单元,网络设备可以根据解析完数据包的时序,确定在时间窗的时间单元先发送哪个数据包对应的控制信息,通过对控制信息采用第一扰码进行加扰,以区分控制信息对应的数据。终端设备通过监测时间窗的各时间单元,采用数据对应的第一扰码对时间窗内各时间单元接收的信息进行解扰,以获取数据包对应的控制信息。从而,网络设备可以先发送先解析完的数据的控制信息,降低上行数据发送的时延。此外,由于终端设备接收控制信息的时间窗包含至少两个时间单元,因此终端设备在该时间窗内可能接收到对应多次上行传输的控制信息,终端设备通过第一扰码对时间窗内各时间单元接收的信息进行解扰以确定控制信息对应的是哪个上行数据包。
下面以具体的实施例对本申请的技术方案进行详细说明。
图3为本申请提供的一个数据发送方法实施例的流程示意图,如图3所示:
S301:网络设备向终端设备发送配置信息。
可选地,网络设备可以通过高层信令向终端设备发送配置信息。
其中,高层信令例如为无线资源控制(Radio Resource Control,简称:RRC)信令。
配置信息包括时间窗的配置信息和/或资源的配置信息,其中,资源包含至少一个资源单元。终端设备通过资源中的至少一个资源单元向网络设备发送数据。
资源的配资信息包括下述至少一种信息:
资源的序号。
所述资源的时频位置。
所述资源中的资源单元的信息。其中,资源单元的信息为如下信息的一种或多种:时域资源信息;频域资源信息;空域资源信息;码域资源信息;导频资源信息。
时间窗的配置信息中包含时间窗的大小和/或时间间隔。例如:时间窗的大小为3个时间单元,时间间隔为4个时间单元,如图4所示,图4为本申请提供的数据发送示意图,若发送数据的资源单元对应的时间单元为0,则时间窗对应的时间单元为4、5和6,则在数据单元0发送的数据的控制信息可能在数据单元4、数据单元5或数据单元6中的任一个。若发送数据的数据单元为1,则时间窗对应的数据单元5、6和7,则数据单元1发送的数据的控制信息可能在数据单元5、数据单元6或数据单元7中的任一个,依次类推。
可选地,时间窗的大小和/或时间间隔也可以通过协议规定。
可选地,配置信息中还可以包含为终端设备配置的最大HARQ进程的数目,其中,网络设备为终端设备配置的最大HARQ进程的数目不大于终端设备上报的其能支持的最大HARQ进程的数目。
S302:终端设备向网络设备发送数据。
网络设备为终端设备配置基于免调度的上行数据传输方式,并为终端设备配置资源用于终端设备的免调度,该配置信息可以是网络设备通过高层信令进行配置。
可选地,终端设备是否采用基于免调度的上行数据传输方式可以依据终端设备的业务类型确定。例如:对于极高可靠性低时延通信(Ultra-reliable/low Latency Communication,URLLC)业务数据包到达,用户则采用基于免调度的上行数据传输方式,对于普通的时延不敏感的增强移动宽带(Enhanced Mobile Broadband,eMBB)业务数据包到达,用户则采用基于调度的上行数据传输方式。
终端设备根据资源的序号,资源的时频位置和/或资源中的资源单元的信息,在网络设备配置的资源中的选取至少一个资源单元,并在选取的资源单元向网络设备发送数据。
可选地,不同的资源可以对应不同的业务类型,更具体地,不同资源可以对应不同的业务性能的需求。
其中,终端设备采用第一扰码对数据加扰;或者,终端设备采用第一扰码对数据的循环冗余校验位进行加扰,以区分数据对应哪个时间单元及哪个终端设备。
其中,第一扰码为多个扰码中的一个,多个扰码中每一个对应于多个HARQ进程号中的一个;
可选地,第一扰码可以是高层信令预先配置的,或者是预先设置在终端设备的。
第一扰码可以是一些比特序列,每个序列对应于一个进程号;也可以是进程号;还可以是基于进程号生成的。
具体地,第一扰码为下述一种或多种:终端设备的标识的部分;终端设备的标识的全部;数据对应的资源池的序号;数据对应的时频资源的序号。
一种可能的实现方式:第一扰码可以为数据对应的时频资源的序号,通过时频资源的序号进行解扰即可区分对应的不同的数据。
另一种可能的实现方式:终端设备发送不同的数据所采用的资源单元来自不同的资源, 则第一扰码可以为数据对应的资源的序号,通过资源的序号进行解扰即可区分对应的不同的数据。
再一种可能的实现方式:第一扰码还可以在上述两种的基础上,结合终端设备的标识的部分或终端设备的标识的全部。
其中,终端设备的标识为网络临时标识(Radio Network Temporary Identity,RNTI)或者国际移动用户识别码(International Mobile Subscriber Identity,IMSI)。
网络设备接收到数据后,采用第一扰码对数据进行解扰;或者,采用第一扰码对数据的循环冗余校验位进行解扰。其中网络设备解扰所采用的第一扰码与终端设备加扰所采用的第一扰码相同,此处不再赘述。
S303:网络设备确定与数据对应的控制信息的时间窗。
该时间窗包含至少两个时间单元。
结合图4,若在数据单元0发送数据包1,则时间窗对应的时间单元为4、5和6,则数据包1的控制信息可能在数据单元4、数据单元5或数据单元6中的任一个。若在时间单元1发送数据包2,则时间窗对应的时间单元为5、6和7,则数据包2的控制信息可能在时间单元5、时间单元6或时间单元7中的任一个,依次类推。
S304:网络设备在时间窗内向终端设备发送数据对应的控制信息。
其中,控制信息是用第一扰码加扰的,用于加扰控制信息的第一扰码指示控制信息对应于数据。
控制信息中包含数据的混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)反馈信息;和/或,控制信息中包含所述数据的调度信息。
数据的调度信息包含所述网络设备为所述的终端设备分配的HARQ进程号信息。
可选地,调度信息包含的HARQ的进程号信息可以和第一扰码对应的HARQ进程号相同或者不同,网络设备可以基于该HARQ进程号为终端设备调度重传或者新传数据。
可选地,该调度信息还可以用于指示所述数据传输正确与否,如果该调度信息指示数据传输失败,则该调度信息可以用于指示数据的重传,该调度信息还包含以下的一种或多种信息:重传数据所占用的时频资源,冗余版本,调制编码方式,功率控制;如果数据传输成功,该调度信息可以用于指示终端设备的数据的新传,该调度信息还包含以下的一种或多种信息:新传数据所占用的时频资源,冗余版本,调制编码方式,功率控制。
结合图4,若网络设备先解析完数据包2,后解析完数据包1,则可以确定在时间单元5传输数据包2的控制信息,在时间单元6传输数据包1的控制信息,从而,发送数据包2的控制信息无需等待数据包1解析完之后才能进行。
S305:终端设备确定与数据对应的控制信息的时间窗。
一种可能的实现方式:终端设备根据时间窗的大小,以及发送数据的时间单元与时间窗之间的时间间隔,确定时间窗控制信息的时间窗,该时间窗包含至少两个时间单元。
该步骤与S303中网络设备确定对应数据的控制信息的时间窗类似,详见S303的详细描述,此处不再赘述。
S306:终端设备在时间窗内接收数据对应的控制信息。
其中,控制信息采用所述第一扰码进行加扰,终端设备采用第一扰码对时间窗内的接收数据进行解扰,以获取所需的控制信息。
其中,终端设备解扰所采用的第一扰码与网络设备加扰所采用的第一扰码相同,此处不再赘述。
控制信息中包含数据的HARQ反馈信息,反馈信息例如:确认ACK或者否认NACK。
结合图4,假设终端设备解析出数据包1的反馈信息为ACK,则清空与数据包1相关的时间单元0对应的HARQ进程的缓存,释放该HARQ进程。
假设,户设备解析出数据包1的反馈信息为NACK,且该次传输已经达到最大重传次数或者超过该数据包传输要求的最大时延,则清空与数据包1相关的时间单元0对应的HARQ进程的缓存,释放该HARQ进程。
假设,数据包1的传输已经达到最大重传次数,且终端设备在时间窗内没有收到来自网络设备的控制信息,则清空与数据包1相关的时间单元0对应的HARQ进程的缓存,释放该HARQ进程。
可选地,控制信息中可以包含数据的调度信息。终端设备收到网络设备的调度信息,该调度信息指示一次新的数据传输,则清空与数据包1相关的时间单元0对应的HARQ进程的缓存,释放该HARQ进程。
本实施例,通过网络设备为终端设备配置时间窗,以及时间窗的时间单元与发送数据的时间单元之间的时序关系,时间窗包含至少两个时间单元,网络设备可以根据解析完数据包的时序,确定在时间窗的时间单元先发送哪个数据包对应的控制信息,通过对控制信息采用第一扰码进行加扰,以区分控制信息对应的数据。终端设备通过监测时间窗的各时间单元,采用数据对应的第一扰码对各时间单元的控制信息解扰,以获取数据包对应的控制信息。从而,网络设备可以先发送先解析完的数据的控制信息,降低上行数据传输的时延。
