Description

数据传输方法及相关产品 技术领域
本发明涉及通信技术领域,具体涉及一种数据传输方法及相关产品。
背景技术
长期演进技术(Long Term Evolution,LTE)***采用共享资源的方式进行用户数据的调度,该种调度方式可以极大程度的利用无线通信资源,但是该种方式需要较大的控制信息开销。在LTE***中,取消了全部电路域的话音业务,而代之以数据域的VoIP业务。但由于话音用户的数量往往比较庞大,LTE又采用共享资源的方式进行用户数据的调度,每次传输都需要相关的控制信息,由于控制信息的开销过大,从而限制了LTE***所能同时支持的用户数。因此,针对这类数据包大小比较固定,到达时间间隔满足一定规律的实时性业务,LTE引入了半静态调度(Semi-Persistent Scheduling,SPS)技术。简单而言,半静态调度方式是指在LTE的调度传输过程中,演进型基站(evolved Node B,eNB)在初始调度通过物理下行控制信道(Physical Downlink Control Channel,PDCCH)指示用户设备(User Equipment,UE)当前的调度信息,UE识别是半静态调度,则保存当前的调度信息,每隔固定的周期在相同的时频资源位置上进行该业务数据的发送或接收。
在LTE***中同一个UE只允许一个半静态调度,因此同一个UE的半静态调度不会发生冲突。目前,在第五代移动通信技术(5-Generation,5G)或新空口(New Ratio,NR)***中,已经提出了同一个UE可以存在多个半静态调度。那么同一个UE的多个半静态调度间可能会存在冲突问题,因此,在5G或NR中,如何避免同一个UE的多个半静态调度间的冲突问题是需要解决的技术问题。
发明内容
本发明实施例提供了一种数据传输方法及相关产品,避免了同一个UE的多个半静态调度间的冲突问题。
第一方面,本发明实施例提供一种数据传输方法,包括:
当混合自动重传请求(Hybrid Automatic Repeat-reQuest,HARQ)缓存(buffer)非空时,用户设备选择之前传输数据所用的上行资源授权(grant)传输需要重传的数据;或者,
当HARQ buffer为空时,用户设备根据所述用户设备所允许的载波接入方式选择当前的一个半静态调度的grant传输新数据,或是选择当前的多个半静态调度的grant传输新数据。
第二方面,本发明实施例提供一种数据传输方法,包括:
网络设备监听用户设备之前传输数据所用的grant的资源,以得到所述用户设备在HARQ buffer非空时,通过之前传输数据所用的grant传输的需要重传的数据;或者,
所述网络设备监听当前的一个半静态调度的grant或当前的多个半静态调度的grant的资源,以得到所述用户设备在HARQ buffer为空时,通过当前的一个半静态调度的grant或当前的多个半静态调度的grant传输的新数据。
第三方面,本发明实施例提供一种用户设备,包括处理单元和通信单元,其中:
所述处理单元,用于当混合自动重传请求缓存(HARQ buffer)非空时,通过所述通信单元选择之前传输数据所用的上行资源授权(grant)传输需要重传的数据;或者,当HARQ buffer为空时,通过所述通信单元根据所述用户设备所允许的载波接入方式选择当前的一个半静态调度的grant传输新数据,或是选择当前的多个半静态调度的grant传输新数据。
第四方面,本发明实施例提供一种网络设备,包括处理单元和通信单元,其中:
所述处理单元,用于通过所述通信单元监听用户设备之前传输数据所用的上行资源授权(grant)的资源,以得到所述用户设备在混合自动重传请求缓存(HARQ buffer)非空时,通过之前传输数据所用的grant传输的需要重传的数据;或者,通过所述通信单元监听当前的一个半静态调度的grant或当前的多个半静态调度的grant的资源,以得到所述用户设备在HARQ buffer为空时,通过当前的一个半静态调度的grant或当前的多个半静态调度的grant传输的新 数据。
第五方面,本发明实施例提供一种用户设备,包括一个或多个处理器、一个或多个存储器、一个或多个收发器,以及一个或多个程序;
所述一个或多个程序被存储在所述存储器中,并且被配置由所述一个或多个处理器执行;
所述程序包括用于执行如本发明实施例第一方面所述的方法中的步骤的指令。
第六方面,本发明实施例提供一种网络设备,包括一个或多个处理器、一个或多个存储器、一个或多个收发器,以及一个或多个程序;
所述一个或多个程序被存储在所述存储器中,并且被配置由所述一个或多个处理器执行;
所述程序包括用于执行如本发明实施例第二方面所述的方法中的步骤的指令。
第七方面,本发明实施例提供一种计算机可读存储介质,其存储用于电子数据交换的计算机程序,其中,所述计算机程序使得计算机执行如本发明实施例第一方面所述的方法。
第八方面,本发明实施例提供一种计算机可读存储介质,其存储用于电子数据交换的计算机程序,其中,所述计算机程序使得计算机执行如本发明实施例第二方面所述的方法。
第九方面,本发明实施例提供一种计算机程序产品,所述计算机程序产品包括存储了计算机程序的非瞬时性计算机可读存储介质,所述计算机程序可操作来使计算机执行如本发明实施例第一方面所述的方法。
第十方面,本发明实施例提供一种计算机程序产品,所述计算机程序产品包括存储了计算机程序的非瞬时性计算机可读存储介质,所述计算机程序可操作来使计算机执行如本发明实施例第二方面所述的方法。
可见,在本方案中,当用户设备的HARQ buffer非空时,重传数据所用的grant与之前传输数据所用的grant相同,因此避免了同一个UE的多个半静态调度间的冲突。另外,当HARQ buffer为空时,当用户设备不允许使用多个半 静态调度的grant传输数据时,用户设备只选用一个半静态调度的grant传输数据,当用户设备允许使用多个半静态调度的grant传输数据时,用户设备才选用多个半静态调度的grant传输数据,进而避免了同一个UE的多个半静态调度间的冲突。
本申请的这些方面或其他方面在以下实施例的描述中会更加简明易懂。

以下分别进行详细说明。

在本文中提及“实施例”意味着,结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例,也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是,本文所描述的实施例可以与其它实施例相结合。
1)用户设备(User Equipment,UE),是一种向用户提供语音和/或数据连通性的设备,例如,具有无线连接功能的手持式设备、车载设备等。常见的终端例如包括:手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device,MID)、可穿戴设备,例如智能手表、智能手环、计步器等。
2)网络设备是指网络侧的节点设备,例如,网络设备可以是蜂窝网络中接入网侧的无线接入网(Radio Access Network,RAN)设备,所谓RAN设备即是一种将终端接入到无线网络的设备,包括但不限于:演进型节点B(evolved Node B,eNB)、无线网络控制器(radio network controller,RNC)、节点B(Node B,NB)、基站控制器(Base Station Controller,BSC)、基站收发台(Base Transceiver Station,BTS)、家庭基站(例如,Home evolved NodeB,或Home Node B,HNB)、基带单元(BaseBand Unit,BBU);再如,网络设备也可以是无线局域网(Wireless Local Area Network,WLAN)中的节点设备,例如接入控制器(access controller,AC),网关,或WIFI接入点(Access Point,AP)等。
3)半静态调度方式是指在调度传输过程中,eNB在初始调度通过物理下行控制信道(Physical Downlink Control Channel,PDCCH)指示用户设备当前的调度信息,用户设备保存当前的调度信息,每隔固定的周期在相同的时频资源位置上进行业务数据的发送或接收。
4)动态调度是指在调度中,由媒体访问控制(Media Access Control, MAC)层(调度器)实时、动态的分配时频资源和允许的传输速率。资源分配采用按需分配方式,每次调度都需要调度信令的交互的调度方式。
5)非自适应重传是HARQ不需要进行授权,用户设备按照上一次传输所使用的资源和调制编码方式进行数据的重传。
6)自适应重传是需要通过SPS-C-RNTI(半静态调度的标识)掩码的PDCCH进行授权传输的重传。
7)“多个”是指两个或两个以上。“和/或”,描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
下面结合附图对本申请的实施例进行描述。
请参阅图1,图1是本申请实施例公开的一种网络构架的示意图。图1所示的网络构架包括用户设备110和网络设备120。目前在5G/NR***中,已经提出了同一个用户设备可以存在多个半静态调度,那么同一个用户设备的多个半静态调度间可能会存在冲突问题。比如,假设某个用户设备有两个半静态调度,第一个半静态调度是从第2ms开始发送,每隔3ms发送一次,第一个半静态调度占用的时频资源位置有:2、5、8、11、14。第二个半静态调度是从第1ms开始发送,每隔4ms发送一次,那么第二个半静态调度占用的时频资源位置有:1、5、9、14。可见,第一个半静态调度和第二个半静态调度在时频资源位置5和14冲突了。
为了解决上述问题,在5G/NR***中,当用户设备120的HARQ buffer非空时,用户设备120选择之前传输数据所用的grant传输需要重传的数据。由于重传数据所用的grant与之前传输数据所用的grant相同,授权调度所使用的时频资源位置也相同。由于之前的传输未出现调度冲突问题,所以使用之前传输数据所用的grant来重传数据,能够避免了同一个UE的多个半静态调度间的冲突。另外,当用户设备120的HARQ buffer为空时,用户设备120根据其所允许的载波接入方式是选择当前的一个半静态调度的grant来传输新数据还是选择当前的多个半静态调度的grant来传输新数据。可见,当用户设备120不允许使用多个半静态调度的grant传输数据时,用户设备120只选用一个半 静态调度的grant传输数据,在用户设备120允许使用多个半静态调度的grant传输数据时,用户设备120才选用多个半静态调度的grant传输数据,进而避免了同一个UE的多个半静态调度间的冲突。
下面结合图1所示的网络构架对本申请实施例提供的数据传输方法进行详细说明。
请参见图2,图2为本申请实施例提供的一种数据传输方法的流程示意图,包括以下步骤:
步骤S201:当用户设备的HARQ buffer非空时,用户设备选择之前传输数据所用的grant传输需要重传的数据;网络设备监听用户设备之前传输数据所用的grant的资源,以得到所述用户设备在所述用户设备的HARQ buffer非空时,通过之前传输数据所用的grant传输的需要重传的数据。
在一示例中,当HARQ buffer非空,且当前传输时间间隔(Transmission Time Interval,TTI)的动态调度的grant没有未翻转的新数据指示(New Date Indicator,NDI)时,所述用户设备选择之前传输数据所用的grant传输需要重传的数据。
具体地,由于没有未翻转的NDI的动态调度grant,说明网络没有要求用户设备在动态调度grant上做重传,但是由于HARQ buffer非空,说明用户设备需要重传,因此用户设备只有在半静态资源上做重传(即非自适应重传)。在这种情况下,如果有多个半静态资源,用户设备选用其他的半静态资源进行重传,可能会有TBS不一致的可能性,所以用户设备应选用原来的半静态资源做重传。
进一步地,当HARQ buffer非空,且当前TTI的动态调度的grant有未翻转的NDI时,所述用户设备选择当前的动态调度的grant传输需要重传的数据。
具体地,有未翻转的NDI的动态调度grant,说明网络希望用户设备重传,并且特地给用户设备发了一个动态调度grant,并希望用户设备在动态调度的grant上进行重传(即自适应重传),从而避免半静态资源的缺点(例如资源分配和MCS固定)。
在一示例中,若之前传输数据所用的grant为一个半静态调度的grant时,所述用户设备选择所述一个半静态调度的grant传输需要重传的数据,网络设 备监听所述一个半静态调度的grant的资源,以得到所述用户设备传输需要重传的数据;
若之前传输数据所用的grant为M个半静态调度的grant时,所述用户设备选择所述M个半静态调度的grant传输需要重传的数据,网络设备监听所述M个半静态调度的grant的资源,以得到所述用户设备传输需要重传的数据,所述M为大于1的整数。
具体地,用户设备的HARQ buffer非空表示用户设备向网络设备发送的数据有没有被网络设备成功接收的数据,用户设备需要将这些没有被网络设备成功接收的数据重新发送给网络设备。在5G/NR***中,用户设备选择之前传输数据所用的半静态调度的grant传输需要重传的数据。比如,用户设备向网络设备发送数据包1~数据包10,其中,数据包2、数据包3没有被网络设备成功接收。假如用户设备之前传输数据所用的半静态调度的grant只要有grant1时,用户设备选择grant1传输数据包2和数据包3。又假如用户设备之前传输数据所用的半静态调度的grant有grant2和grant3时,用户设备选择grant2和grant3传输数据包2和数据包3。其中,用户设备之前传输数据所用的半静态调度的grant有多个时,这多个半静态调度的grant的资源不会冲突。
可见,由于重传数据所用的grant与之前传输数据所用的grant相同,授权调度所使用的时频资源位置也相同。由于之前的传输未出现调度冲突问题,所以使用之前传输数据所用的grant来重传数据,能够避免了同一个UE的多个半静态调度间的冲突。
进一步地,用户设备之前传输数据所用的半静态调度的grant有多个,需要重传的数据也有多个,若之前传输数据i所用的半静态调度的grant为grant1时,用户设备选择grant1传输数据i,所述数据i为需要重传的多个数据中的其中一个,grant1为用户设备之前传输数据所用的多个半静态调度的grant中的其中一个。比如,用户设备向网络设备发送数据包1~数据包10,其中,数据包2、数据包3没有被网络设备成功接收。用户设备之前传输数据所用的半静态调度的grant有grant2和grant3,用户设备之前用grant2传输数据包2,用户设备之前用grant3传输数据包3,那么重传时用户设备还选用grant2重传数据包2,用户设备还选用grant3重传数据包3。
进一步地,用户设备之前传输数据所用的半静态调度的grant有多个,需要重传的数据也有多个,若之前传输数据i所用的半静态调度的grant为grant1时,用户设备选择多个半静态调度的grant中除了grant1之外的grant传输数据i,所述数据i为需要重传的多个数据中的其中一个,grant1为用户设备之前传输数据所用的多个半静态调度的grant中的其中一个。比如,用户设备向网络设备发送数据包1~数据包10,其中,数据包2、数据包3没有被网络设备成功接收。用户设备之前传输数据所用的半静态调度的grant有grant2和grant3,用户设备之前用grant2传输数据包2,用户设备之前用grant3传输数据包3,那么重传时用户设备还选用grant3重传数据包2,用户设备还选用grant2重传数据包3。
或者,步骤S202:当HARQ buffer为空时,所述用户设备根据所述用户设备所允许的载波接入方式选择当前的一个半静态调度的grant传输新数据,或是选择当前的多个半静态调度的grant传输新数据;所述网络设备监听当前的一个半静态调度的grant或当前的多个半静态调度的grant的资源,以得到所述用户设备在用户设备的HARQ buffer为空时,通过当前的一个半静态调度的grant或当前的多个半静态调度的grant传输的新数据。
在一示例中,当HARQ buffer为空,当前有N个半静态调度的grant,且不允许所述用户设备使用非单载波接入方式时,所述用户设备选择所述N个半静态调度的grant中的一个grant传输新数据,网络设备监听所述N个半静态调度的grant的资源,以得到所述用户设备传输的新数据,所述N为大于1的整数;
当HARQ buffer为空,当前有N个半静态调度的grant,且允许所述用户设备使用非单载波接入方式时,所述用户设备选择所述N个半静态调度的grant中的多个grant传输新数据,网络设备监听所述N个半静态调度的grant的资源,以得到所述用户设备传输的新数据。
具体地,用户设备的HARQ buffer为空表示用户设备没有需要向网络设备重传的数据。在5G/NR***中,假如当前用户设备有N个半静态调度的grant,但是用户设备当前情况不允许用户设备使用非单载波接入方式(非单载波接入方式比单载波接入方式需要更好的发送功率和更高的信噪比,并且抗干扰能力 不如单载波,假设用户设备处于小区的边缘,由于用户设备当前的网络情况不好,因此用户设备当前情况不允许用户设备使用非单载波接入方式),用户设备从这N个半静态调度的grant中选择一个grant来传输新数据。假如当前用户设备有N个半静态调度的grant,且用户设备当前情况允许用户设备使用非单载波接入方式,那么用户设备从这N个半静态调度的grant中选择多个grant来传输新数据。
可见,当用户设备不允许使用多个半静态调度的grant传输数据时,用户设备只选用一个半静态调度的grant传输数据,在用户设备允许使用多个半静态调度的grant传输数据时,用户设备才选用多个半静态调度的grant传输数据,进而避免了同一个UE的多个半静态调度间的冲突。
进一步地,用户设备从这N个半静态调度的grant中选择多个grant来传输新数据,这多个grant可以是时频资源位置相邻的多个grant。比如,N个半静态调度的grant有grant1、grant2、grant3、grant4和grant5,其中,grant2、grant3和grant4的时频资源位置是相邻的,那么用户设备选择grant2、grant3和grant4来传输新数据。
进一步地,用户设备从这N个半静态调度的grant中选择多个grant来传输新数据,这多个grant可以是传输块大小(transmission-block size,TBS)大小超过预设阈值的多个grant。比如,N个半静态调度的grant有grant1、grant2、grant3、grant4和grant5,这5个grant中TBS超过预设阈值的grant有:grant2、grant3和grant4,那么用户设备选择grant2、grant3和grant4来传输新数据。
在一示例中,所述用户设备选择所述N个半静态调度的grant中的TBS最大的一个grant传输新数据,网络设备监听所述N个半静态调度的grant中的TBS最大的一个grant的资源,以得到所述用户设备传输的新数据。比如,N个半静态调度的grant有grant1、grant2、grant3、grant4和grant5,这5个grant中,BS最大的grant为grant5,那么用户设备选择grant5来传输新数据。
具体地,当用户设备有多个半静态调度的grant时,如果网络设备不知道用户设备使用的是哪个grant传输数据,网络设备是要监听N个半静态调度的grant的资源,这样网络设备消耗较大,因此,预先约定好当用户设备只能选用一个半静态调度的grant传输数据时,选用TBS最大的那个grant,网络设 备只监听这个TBS最大的grant的资源即可,进而降低了网络设备的开销。
在一示例中,所述用户设备选择所述N个半静态调度的grant中的索引值(Index)最大或最小的一个grant传输新数据,网络设备监听所述N个半静态调度的grant中的Index最大或最小的一个grant的资源,以得到所述用户设备传输的新数据。比如,N个半静态调度的grant有grant1、grant2、grant3、grant4和grant5,这5个grant的Index分别是1-5,那么Index最大的grant为grant5,Index最小的grant为grant1,那么用户设备选择grant1或grant5来传输新数据。
具体地,当用户设备有多个半静态调度的grant时,如果网络设备不知道用户设备使用的是哪个grant传输数据,网络设备是要监听N个半静态调度的grant的资源,这样网络设备消耗较大,因此,预先约定好当用户设备只能选用一个半静态调度的grant传输数据时,选用Index最大或最小的那个grant,网络设备只监听这个Index最大或最小的grant的资源即可,进而降低了网络设备的开销。
在一示例中,当HARQ buffer为空,且当前有动态调度的grant时,所述用户设备选择当前的动态调度的grant传输新数据,网络设备监听当前的动态调度的grant的资源,以得到所述用户设备传输的新数据。由于动态调度可实时进行调整,假如用户设备当前有动态调度的grant时,用户设备选择该动态调度的grant来传输新数据,可保证资源不冲突。

在一示例中,所述程序还用于执行以下步骤的指令:
当HARQ buffer非空,且当前TTI的动态调度的grant有未翻转的NDI时,选择当前的动态调度的grant传输需要重传的数据。
可见,在本方案中,当用户设备的HARQ buffer非空时,重传数据所用的grant与之前传输数据所用的grant相同,因此避免了同一个UE的多个半静态调度间的冲突。另外,当HARQ buffer为空时,当用户设备不允许使用多个半静态调度的grant传输数据时,用户设备只选用一个半静态调度的grant传输数据,当用户设备允许使用多个半静态调度的grant传输数据时,用户设备才选用多个半静态调度的grant传输数据,进而避免了同一个UE的多个半静态调 度间的冲突。
