Definitions

  • the present invention relates to the field of mobile communications, and in particular, to a method and apparatus for data transmission.
  • the transmission of services in the LTE (Long Term Evolution) system is based on base station scheduling, and the basic time unit of scheduling is one subframe.
  • the duration of one subframe is generally 1 ms, one subframe generally includes two slots, one slot generally includes seven time domain symbols, and the time domain symbol refers to OFDM or SC-FDMA symbols in the time domain dimension.
  • the specific scheduling process includes the base station transmitting a control channel (such as a PDCCH), the UE detecting the control channel in the subframe, and performing downlink data channel reception or uplink data channel transmission according to the detected scheduling information carried in the control channel.
  • the control channel may carry scheduling information of a downlink data channel (such as a PDSCH) or an uplink data channel (such as a PUSCH), and the scheduling information includes control information such as resource allocation information, modulation and coding mode, and HARQ.
  • the LTE adopts the HARQ mechanism.
  • the UE after receiving the transport block TB carried in the PDSCH, the UE feeds back the ACK on the uplink if the reception is correct, and returns the NACK on the uplink if it is not correct.
  • the UE After receiving the PDSCH in the subframe n-4, the UE feeds back the ACK/NACK in the subframe n.
  • the timing relationship between the PDSCH reception and the corresponding ACK/NACK feedback is related to the TDD uplink and downlink configuration.
  • the base station may cause the UE to retransmit the TB carried in the last PDSCH transmission, and the base station may retransmit the received information of the TB in the received PDSCH and the previously not correctly received.
  • the received information of the TB is HARQ combined to improve the receiving performance.
  • 5G In addition to eMBB, which further enhances 4G mobile broadband MBB, 5G also supports mMTC and URLLC.
  • URLLC there are two basic requirements. One is the short delay caused by the service emergency. For example, the upstream and downstream user plane delays specified in the current requirements are both 0.5ms; the second is the high reliability, such as within 1ms. A packet error rate of 10 ⁇ (-5) is reached.
  • a bursty URLLC emergency service can punct eMBB services that have already been transmitted.
  • the so-called puncturing that is to say, the service mapping of the URLLC covers a part of the resources of the downlink data channel of the eMBB that has started to transmit in the time-frequency resource.
  • the performance of the initial transmission or retransmission of the eMBB is lost, that is, the current transmission of the TB of the eMBB is highly unlikely to be correctly received by the eMBB UE.
  • the LTE LTE system branch or the NR system branch of the 5G can adopt the HARQ mechanism.
  • the UE after the UE receives the TB carried in the downlink data channel, if the receiving is correct, the UE feeds back the ACK on the uplink; if incorrect , then NACK is fed back on the uplink.
  • Current data scheduling and HARQ are in terabytes. Specifically, even if one CB in the TB is not correctly received, the TB CRC of the entire TB cannot be verified, that is, the UE still considers that the TB is not correctly received, and then feeds back the NACK to the base station. After receiving the NACK, the base station can only consider that the entire TB is not correctly received by the UE.
  • the base station subsequently performs retransmission scheduling on the entire TB of the UE. Even if the entire TB is retransmitted, the UE cannot correctly receive the TB by means of HARQ combining.
  • the UE cannot know which CB was punctured by the URLLC during the last transmission, so the UE reverses While the NACK is being fed, the UE's own HARQ buffer may store the URLLC service instead of its own CB. Therefore, the HARQ combining with the retransmitted CB cannot obtain the HARQ combining gain, but the CB cannot be correctly received again. In the end, it will most likely trigger the retransmission of the RLC layer, resulting in a significant drop in system efficiency.

Description

一种数据传输的方法和装置 技术领域
本发明涉及移动通信领域,尤其涉及一种数据传输的方法和装置。
背景技术
LTE(Long Term Evolution,长期演进)系统中业务的传输是基于基站调度的,调度的基本时间单位是一个子帧。一个子帧的时长一般为1ms,一个子帧一般包括两个时隙,一个时隙一般包括7个时域符号,时域符号指时间域维度上的OFDM或SC-FDMA符号。具体的调度流程包括基站发送控制信道(比如PDCCH),UE在子帧中检测控制信道,并根据检测出的控制信道中承载的调度信息来进行下行数据信道的接收或上行数据信道的发送。该控制信道可以承载下行数据信道(比如PDSCH)或上行数据信道(比如PUSCH)的调度信息,该调度信息包括比如资源分配信息,调制编码方式以及HARQ等控制信息。
LTE采用HARQ机制,以下行为例,UE接收到PDSCH中承载的传输块TB之后,如果接收正确,则UE在上行链路上反馈ACK;如果不正确,则在上行链路上反馈NACK。对于FDD,UE在子帧n-4接收到PDSCH之后,会在子帧n反馈ACK/NACK;对于TDD,PDSCH接收与其对应的ACK/NACK反馈的时序关系与TDD上下行配置相关。基站如果接收到UE反馈的是NACK,则基站后续会让UE重新发送上次PDSCH传输中承载的TB,进而基站可以将重传接收到的PDSCH中的TB的接收信息与之前没有正确接收的该TB的接收信息进行HARQ合并来提升接收性能。
5G从技术特性上除了对4G的移动宽带MBB进行进一步增强的eMBB之外,还支持mMTC和URLLC。对于URLLC,有两个基本要求,其一是业务紧急带来的短时延,比如目前需求里规定的上下行用户面时延均为0.5ms;其二是超高的可靠性,比如1ms内达到10^(-5)的误包率。为了支持灵活的eMBB与URLLC的资源复用,一种方案是,突发的URLLC紧急业务可以对于已经发生传输的eMBB业务进行打孔。所谓打孔,也就是说URLLC的业务映射在时频资源时覆盖掉已经开始传输的eMBB的下行数据信道所在的资源中的一部分资源。这样,虽然保证了URLLC业务的短时延要求,但对eMBB的该次初传或重传对造成性能损失,即eMBB的TB的当次传输很大概率地不会被eMBB UE所正确接收。
5G的LTE持续演进系统分支或NR系统分支均可以采用HARQ机制,以下行为例,UE接收到下行数据信道中承载的TB之后,如果接收正确,则UE在上行链路上反馈ACK;如果不正确,则在上行链路上反馈NACK。当前数据调度和HARQ是以TB为单位的。具体的,TB中即使有一个CB未被正确接收,整个TB的TB CRC也是无法被校验通过的,即UE还是会认为该TB未被正确接收,进而反馈NACK给基站。基站接收到该NACK后,只能认为整个TB未被UE正确接收,虽然实际上大部分CB都已经被正确接收了,进而基站后续会对UE的整个TB都进行重传调度。即使整个TB被重传,UE无法通过HARQ合并的方式正确接收该TB。UE无法获知哪个CB在上一次传输时被URLLC打孔,因此UE反 馈NACK的同时,UE自己的HARQ缓存器中存储的可能是URLLC的业务而非自己的CB,因此与重传的该CB进行HARQ合并不但无法获得HARQ合并增益,反而造成该CB再次无法正确接收,最终会很可能会触发RLC层重传,造成系统效率大幅度下降。
因此,针对突发的URLLC紧急业务对于已经发生传输的eMBB业务进行打孔的场景,或者扩展到eMBB传输过程中遇到时间长度较短的突发干扰的场景,有必要提供一种更高效的数据传输处理方法。

具体实施方式
下面将结合附图,对本发明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发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有付出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
图1示出了本发明实施例应用的通信系统100。该通信系统100可以包括至少一个无线接入网设备110和位于无线接入网设备110覆盖范围内的多个终端设备120。图1示例性地示出了一个无线接入网设备和两个终端设备,可选地,该通信系统100可以包括多个无线接入网设备并且每个无线接入网设备的覆盖范围内可以包括其它数量的终端设备,本发明实施例对此不做限定。
可选地,该无线通信系统100还可以包括网络控制器、移动管理实体等其他网络实体,本发明实施例不限于此。
本发明实施例所应用的通信系统可以为全球移动通讯(Global System of Mobile communication,GSM)系统、码分多址(Code Division Multiple Access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统、通用分组无线业务(General Packet Radio Service,GPRS)、长期演进(Long Term Evolution,LTE)系统、LTE频分双工(Frequency Divison Duplex,FDD)系统、LTE时分双工(Time Division Duplex,TDD)、通用移动通信系统(Universal Mobile Telecommunication System,UMTS),及其他应用正交频分(OFDM)技术的无线通信系统等。本发明实施例描述的系统架构以及业务场景是为了更加清楚的说明本发明实施例的技术方案,并不构成对于本发明实施例提供的技术方案的限定,本领域普通技术人员可知,随着网络架构的演变和新业务场景的出现,本发明实施例提供的技术方案对于类似的技术问题,同样适用。
在本发明实施例中所涉及的无线接入网设备可用于为终端设备提供无线通信功能。所述无线接入网设备可以包括各种形式的宏基站,微基站(也称为小站),中继站,接入点等。所述无线接入网设备可以是GSM或CDMA中的基站(Base T接入网sceiver Station,BTS),也可以是WCDMA中的基站(NodeB,NB),还可以是LTE中的演进型基站(Evolutional Node B,eNB或e-NodeB),以及可以是5G网络中对应的设备gNB。为方便描述,本发明所有实施例中,上述为终端设备提供无线通信功能的装置统称为无线接入网设备。
在本发明实施例中,所述终端设备也可称之为用户设备(User Equipment,UE)、移动台(Mobile Station,MS)、移动终端(Mobile Terminal)等,该终端设备可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网进行通信,例如,终 端设备可以是移动电话(或称为“蜂窝”电话)、具有移动终端的计算机等,例如,终端设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语言和/或数据。本发明实施例中不做具体限定。
当前无线系统中的数据调度和相应的HARQ反馈以及可能的HARQ重传都是以传输块TB为单位。以下行数据调度为例,eNB调度给UE的一个PDSCH一般包含一个TB或两个TB。具体的,如果该PDSCH中包括一个码字,比如此时为非MIMO调度,则对应一个TB;如果该PDSCH中包括两个码字,比如此时为MIMO调度,则分别对应两个TB。为了描述方便,本文以单码字调度对应的一个TB为例,多码字的情况可以类似的针对单码字情况进行分别处理。如果UE正确接收该PDSCH中的该TB,则UE在上行链路反馈ACK,反之反馈NACK;如果基站接收到了该UE反馈的NACK,在后续还会对该未被UE正确接收的TB进行重传调度。
考虑到编译码复杂度以及快速编译码处理的好处,一个TB可以被分成多个编码块CB分别进行信道编译码。例如,对于Turbo码,一般最大CB的比特数为6144,即如果一个TB的比特数超过了6144,则需要将该TB拆分成多个CB分别编译码;对于LDPC,一般最大CB的比特数为2000左右,即可以支持拆分为更多CB进行并行编译码。一般来说,每个CB都具有独立的校验功能,比如以Turbo码为例,每个CB在编码前都会加CB CRC,这样UE在对每个CB进行译码后,通过CRC校验就可以确定当前CB是否被正确译码;对于LDPC,每个CB也可以加CB CRC,或者LDPC的编码矩阵本身就具备校验功能,即LDPC的每个CB也都是可以具备校验功能的。
为了实现快速编译码,以下行为例,编码后的调制符号在进行物理资源映射时采用先频域后时域的顺序进行映射,且不进行CB间的交织,即按照CB的顺序来映射。这样的好处是,UE缓存到一个CB就可以开始译码,而不必等到把该PDSCH中所有CB都缓存下来后才能开始译码。
对于URLLC对eMBB进行打孔,考虑到URLLC的数据发送时间一般较短,且URLLC很可能采用比eMBB更短的时域符号和/或更短的子帧,因此URLLC可能只会对eMBB的PDSCH中的很少量的CB的时频资源位置进行打孔,比如对1或2个CB的时频资源位置进行打孔。可以看到,URLLC通过对eMBB的PDSCH进行打孔保证自身短时延要求的同时,只会对eMBB的PDSCH中的TB中的多个CB中的少量CB造成影响,假设eMBB的PDSCH的TB有30个CB,其中由于被URLLC打孔造成未被UE正确接收的CB只有1到2个。但是,TB中即使有一个CB未被正确接收,整个TB的TB CRC也是无法被校验通过的,即UE还是会认为该TB未被正确接收,进而反馈NACK给基站。基站接收到该NACK后,只能认为整个TB未被UE正确接收,虽然实际上大部分CB都已经被正确接收了,进而基站后续会对UE的整个TB都进行重传调度。即使整个TB被重传,UE无法通过HARQ合并的方式正确接收该TB,因为UE无法获知哪个CB在上一次传输时被URLLC打孔,因此UE反馈NACK的同时,UE自己的HARQ缓存器中存储的可能是URLLC的业务而非自己的CB,因此与重传的该CB进行HARQ合并不但无法获得HARQ合并增益,反而造成该CB再次无法正确接收,最终会很可能会触发RLC层重传,造成系统效率大幅度下降。
为了解决上述由于少量CB被URLLC打孔造成的eMBB TB整体重传所带来的系统效率下降的问题,一种现有技术是采用基于CB为单位的HARQ反馈和重传。具体的,UE对整个TB中的每个CB是否被UE正确接收分别进行HARQ反馈,基站对未被UE正确接收的CB做重传或采用HARQ初传来重新传输某些未被UE正确接收的CB。采用了基于CB为单位的HARQ后,基站就知道TB中的哪些CB未被UE正确接收,其中包括被URLLC打孔的CB,也可能包括未被URLLC打孔但由于信道衰落等其他原因造成的未被UE正确接收的CB。对于被URLLC打孔的CB,基站后续会直接进行初传调度,来解决UE的HARQ缓存器被URLLC污染而造成无法通过HARQ合并来接收重传包;对于未被URLLC打孔但由于信道衰落等其他原因造成的未被UE正确接收的CB,基站可以正常进行重传调度,UE可以正常进行HARQ合并来提高正确接收的概率。
LTE持续演进系统或NR系统中业务的传输还是基于基站调度的。正常的数据发送流程为数据原始比特进行CRC添加以及编码形成码字;码字通过加扰和星座调制形成调制符号;将调制符号映射到时间、频率和空间资源上,这里空间资源相对于使用多天线的传输方式。最后,变换到时域并发送,这就是整个基带的数据发送流程。
在一个实施例中,为了解决HARQ合并带来的HARQ缓存器污染的问题,无线接入网设备通知终端设备受影响编码块的指示信息,终端设备确定未正确接收的CB,使用针对该CB重传的数据包做数据恢复。当基站对eMBB UE进行初传或重传调度时,通知该eMBB UE当前TB的上一次传输(初传或上一次重传)时哪些CB被URLLC的传输所打孔;该UE获取到该打孔信息后,对于之前没有正确接收的CB进行HARQ合并时,对于被打孔的CB就不进行HARQ合并了,而对于未被打孔的CB可以照常进行HARQ合并。
参考图2,本发明提供的数据传输方法的一个实施例,包括:
S201:无线接入网设备向终端设备发送控制信息和受影响编码块的指示信息,该控制信息用于所述无线接入网设备调度所述终端设备的至少一个传输块,所述至少一个传输块中的每个传输块中包括至少一个编码块,所述受影响编码块为所述至少一个传输块中的至少一个编码块。
可选的,该至少一个传输块可以为HARQ初传的传输块或HARQ重传的传输块。
一个实施例中,该控制信息可以承载在下行控制信道中。可选的,该控制信息可以包括承载该TB的下行数据信道的资源分配信息,调制编码方式和HARQ等控制信息。可选的,该控制信息可以调度一个子帧中的一个TB,也可以是分别调度多个子帧中的多个TB。需要说明的是,这里提到的子帧概念上是调度TB的最小时间粒度,将来演进的LTE系统或NR系统中可能会用到其他名称,比如微子帧,时隙,微时隙等,但本质上是一样的,本发明中以子帧为例进行描述。
可选的,该发送控制信息和受影响编码块的指示信息可以承载在同一条消息中。例如,该受影响编码块的指示信息和发送控制信息承载在下行控制信道中。可选的,该发送控制信息和受影响编码块的指示信息也可以承载在不同的消息中,该控制信息是承 载在下行控制信道中,而该受影响编码块的指示信息可以是用独立的控制信道来承载。
一个实施例中,如果所述至少一个传输块为HARQ重传的传输块,所述控制信息中携带所述受影响编码块的指示信息;如果所述至少一个传输块为HARQ初传的传输块,所述控制信息中不携带所述受影响编码块的指示信息。另一个实施例中,该至少一个传输块为HARQ重传的传输块,所述受影响编码块的指示信息携带在所述控制信息中的调制编码指示字段中。
可选的,受影响编码块指传输块在被传输时的所占资源中被其他传输信息改写或干扰的资源所对应的编码块,受影响可以包括如下方式(但也不限定于如下有限的方式):
a)无线接入网设备传输TB中受影响编码块的资源被其他业务数据(比如URLLC)所覆盖(也可以称为改写),即无线接入网设备在该受影响编码块的资源上不发送原本该发送的该受影响编码块的信息,而是在该资源上发送上述其他业务数据的信息;
b)无线接入网设备传输TB中受影响编码块的的资源传输的信息被其他业务数据(比如URLLC)所干扰,即叠加发送,具体指该资源上照常去发送该TB的传输信息,且在相同的该资源上还发送上述其他业务数据的信息。
S202:终端设备根据该受影响编码块的指示信息确定受影响编码块。
终端设备接收无线接入网设备发送的控制信息和受影响编码块的指示信息,终端设备根据该指示信息确定受影响编码块。
终端设备在收到该受影响编码块的指示信息之后,根据所述至少一个传输块所占的资源量或所述至少一个传输块所包含的编码块的数量来解析所述受影响编码块的指示信息。可选的,上述受影响编码块的指示信息的解析粒度可以根据所述至少一个传输块所占的资源量或所述至少一个传输块所包含的编码块的数量确定。
S203:无线接入网设备向终端设备至少发送所述至少一个传输块中除所述受影响编码块之外的至少一个编码块。
需要说明的是,受影响编码块有可能被打孔或干扰,如果是打孔,则该受影响CB在编码、星座调制后的映射资源的部分或全部可以被无线接入网设备用来传输其他紧急业务,即无线接入网设备可以不在该部分或全部资源上发送该受影响CB在编码、星座调制后的信息;如果是干扰,则该受影响CB在编码、星座调制后的映射资源上,无线接入网设备仍然照常发送该该受影响CB在编码、星座调制后的信息,只是还可以在该受影响CB在编码、星座调制后的映射资源的部分或全部上叠加发送其他紧急业务。
S204:终端设备根据所述控制信息以及确定的所述受影响编码块接收所述至少一个传输块。
一个实施例中,如果所述至少一个传输块为HARQ重传的传输块,所述终端设备不对所述受影响编码块对应的数据进行HARQ合并。
另一个实施例中,如果所述至少一个传输块为HARQ初传的传输块且所述受影响编码块未被正确接收,所述终端设备不在HARQ缓存器中存储所述受影响编码块对应的数 据。
该实施例中,该受影响编码块的指示信息可以是显性的指示或隐性的指示,也可以是直接的指示或间接的指示。该受影响编码块的指示信息可以包含多种信息。
一个实施例中,受影响编码块的指示信息包括:所述受影响编码块的标识信息。进一步的,受影响编码块的标识信息可以包括:1)所述受影响编码块的索引;或2)所述受影响编码块的组索引;或3)第一编码块的索引,所述受影响编码块包括顺序上在所述第一编码块之前或之后的编码块,或者,所述受影响编码块包括所述第一编码块以及顺序上在所述第一编码块之前或之后的编码块;或4)第一编码块组的索引,所述受影响编码块包括顺序上在所述第一编码块组之前或之后的编码块,或者,所述受影响编码块包括所述第一编码块组以及顺序上在所述第一编码块组之前或之后的编码块。需要说明的是,上述第一编码块也可以理解为参考编码块。
另一个实施例中,该受影响编码块的指示信息包括:所述受影响编码块对应的资源的标识信息。具体的,受影响编码块对应的资源的标识信息可以包括:1)所述受影响编码块对应的资源的索引;或2)所述受影响编码块对应的资源的组索引;或3)第一编码块对应的资源的索引,所述受影响编码块包括顺序上在所述第一编码块之前或之后的编码块,或者,所述受影响编码块包括所述第一编码块以及顺序上在所述第一编码块之前或之后的编码块;或4)第一编码块对应的资源组的索引,所述受影响编码块包括顺序上在所述第一编码块组之前或之后的编码块,或者,所述受影响编码块包括所述第一编码块组以及顺序上在所述第一编码块组之前或之后的编码块。需要说明的是,上述第一编码块对应的资源也可以理解为参考编码块对应的资源。可选的,上述受影响编码块对应的资源可以为当前传输该传输块时的其中的受影响CB所占的资源,也可以为相对于当前传输的该传输块的上一次传输时(这里的上一次传输可以为该传输块的HARQ初传,也可以为该传输块的上一次HARQ重传)的其中受影响CB所占的资源。
本实施例中的顺序,可以是时间、频率或者逻辑上的顺序。对于时间顺序,可以指传输块包括的多个编码块在资源映射时采用先频率后时间的顺序,这样使得该多个编码块的资源就是按照时间的顺序进行映射的,比如时域符号1和2上映射编码块1,时域符号3和4上映射编码块2,等等,需要说明的是,上述先频率后时间的映射方式只是举例,其他映射方式只要能体现出多个编码块的资源按照时间顺序进行映射的方案都是不排除的;对于频率顺序,可以指传输块包括的多个编码块在资源映射时采用先时间后频率的顺序,这样使得该多个编码块的资源就是按照频率的顺序进行映射的,比如频域子载波1至12上映射编码块1,频域子载波13和24上映射编码块2,等等,需要类似说明的是,上述先时间后频率的映射方式也只是举例,其他可以达到类似频率顺序的方案都不排除;对于逻辑顺序,是指在资源映射前可以给多个编码块进行逻辑排序,但在资源映射时可以打乱上述逻辑排序,即根据逻辑排序与物理资源映射之间的预设对应关系来进行物理资源映射。
另一个实施例中,该受影响编码块的指示信息可以包括:是否存在所述受影响编码块的信息。比如,就是指示两个状态,其中一个状态是不被影响,即没有被打孔或干扰;另一个状态是被影响,即被打孔或干扰。这种指示方式的粒度是最粗的,即无法具体指 示该TB中哪些CB被影响,或无法具体指示该TB映射的资源上哪部分资源被影响,但是该指示方式最节省信令开销。终端设备如果确定被影响,则对于该TB的所有未接收正确的CB都不进行HARQ合并,虽然有些为正确接收的CB并没有被打孔或干扰的影响。具体比如该受影响编码块的指示信息为1比特的显示指示或两种加扰方式的隐示指示方法,其他类似的指示方法也不做限定。
以受影响编码块的指示信息包含受影响编码块的索引为例,假设一个TB包括4个CB,可以用4个比特分别指示该4个CB中具体哪个或哪几个被影响,其他显示或隐示的指示方式都不做限定。以受影响编码块的指示信息包含受影响编码块的组索引为例,参考图3,一个TB包括8个CB,即4个CBG,可以用4个比特分别指示该4个CBG中具体哪个或哪几个被影响。具体的4个比特的状态为‘1000’,即第一个CBG被影响。
一个TB最大有可能会包括几十个CB,比如64个,这样用64比特来指示的开销是无法承受的。因此,一个节省开销的方法是,受影响编码块的指示信息用于指示参考受影响CB,然后终端设备通过预设规则确定该参考受影响CB所关联的其他潜在受影响CB,需要说明的是,该其他潜在受影响CB未必一定是受影响的CB。具体以图4为例,假设一个TB包括8个CB,图4所示第3个CB为受影响CB,这指示信息就可以指示该第3个CB为受影响CB,然后终端设备根据预设规则确定该参考受影响CB后面的CB都是潜在受影响CB,即第6个CB也被认为是受影响CB,虽然该第6个CB实际未受影响。而第2个CB为未受影响CB,因此终端设备接收该TB的重传调度时,对于第2个CB采用HARQ合并,而对于第3个和第6个CB不采用HARQ合并。
可以看到,上述预设规则为:所述参考受影响元素所关联的受影响元素包括所述参考受影响元素以及顺序上在所述参考受影响元素之前或之后的受影响元素。需要说明的是,这里的顺序可以为绝对时间上的顺序和/或绝对频率上的顺序,也可以为逻辑上的索引号的顺序,如图4中所示的就是索引号的顺序也可以理解为时间上CB的映射顺序是从前到后。
该受影响编码块的指示信息也可以包含受影响编码块对应的资源的标识信息。该资源可以是时域资源或者频域资源。传输块最终会映射到时频资源上,比如以控制信息调度1个子帧中的1个TB为例,可以把1个子帧分为6个时间片段,则受影响编码块的指示信息就可以指示其中的1个或多个时间片段为受影响时间片段。因此,终端设备就可以根据受影响时间片段来确定这些受影响时间片段上被基站映射的该TB中的哪些CB为受影响CB,进而确定在重传接收时,不对这些受影响CB进行HARQ合并,其他方面的描述如上述实施例。对于多个子帧以及其他资源部分的划分方式,比如时频两维的划分方式等,都不做限定。
可选的,上述受影响编码块的指示信息的解析粒度可以根据所述至少一个传输块所占的资源量或所述至少一个传输块所包含的编码块的数量确定。
以固定状态数的指示信息为例,比如4个比特的16个状态为例,如果控制信息调度了2个子帧的下行数据,每个子帧包括一个TB,一个TB包括6个CB,则受影响编码块的指示信息的前2个比特用于指示第1个子帧中的受影响CB或CBG的解析,受影响编码块的指示信息的后2个比特用于指示第2个子帧中的受影响CB或CBG的解析。具体的,每个子帧按 照CBG=2个CB为粒度来指示,对于第1个子帧,受影响编码块的指示信息的前2个比特的状态‘00’表示未被影响,‘01’表示第1个CBG为参考受影响CBG,‘10’表示第2个CBG为参考受影响CBG,‘10’表示第3个CBG为参考受影响CBG,对于第2个子帧的指示方法类似。如果控制信息调度了1个子帧的下行数据,则4比特可以按照CB的粒度来指示,具体的,‘0000’表示未被影响,‘0001’至‘0110’表示第1个至第6个CB哪个为参考受影响CB。
以固定状态数的指示信息为例,比如4个比特的16个状态为例,如果控制信息调度了2个子帧的下行数据,每个子帧包括6个时间片段,则受影响编码块的指示信息的前2个比特用于指示第1个子帧中的受影响时间片段的解析,受影响编码块的指示信息的后2个比特用于指示第2个子帧中的受影响时间片段的解析。具体的,每个子帧按照时间片段组=2个时间片段为粒度来指示,对于第1个子帧,受影响编码块的指示信息的前2个比特的状态‘00’表示未被影响,‘01’表示第1个时间片段组为参考受影响时间片段组,‘10’表示第2个时间片段组为参考受影响时间片段组,‘10’表示第3个时间片段组为参考受影响时间片段组,对于第2个子帧的指示方法类似。如果控制信息调度了1个子帧的下行数据,则4比特可以按照时间片段的粒度来指示,具体的,‘0000’表示未被影响,‘0001’至‘0110’表示第1个至第6个CB哪个为参考受影响时间片段。如果指示了某个时间片段,则终端设备可以确定该时间片段上所映射的CB或CBG,也就确定了受影响CB或CBG。
本实施例中,由于无线接入网设备向终端设备指示了受影响编码块,则终端设备可以对受影响编码块不做缓存或终端设备不对受影响编码块对应的数据进行HARQ合并,解决了HARQ缓存器污染问题,在时间长度较短的突发干扰的场景下,保证数据传输的效率。该实施例保证了URLLC突发业务的低时延需求,且同时解决了URLCC和eMBB业务之间的高效灵活复用。
参考图5,本发明数据传输方法的另一个实施例,受影响编码块的指示信息携带在HARQ重传的传输块对应的控制信息中。该方法包括:
S501:无线接入网设备向终端设备发送控制信息,该控制信息用于所述无线接入网设备调度所述终端设备的至少一个传输块,所述至少一个传输块中的每个传输块中包括至少一个编码块。
该终端设备接收该控制信息。
S502:无线接入网设备向终端设备发送至少一个传输块,终端设备根据该控制信息接收该至少一个输块。
S503:终端设备向无线接入网设备进行ACK/NACK反馈。
终端设备根据该传输块的接收情况,向无线接入网设备进行ACK/NACK反馈。
S504:在收到NACK反馈时,无线接入网设备向终端设备发送重传控制信息,该重传控制信息用于所述无线接入网设备调度所述终端设备的至少一个传输块,所述至少一个传输块中的每个传输块中包括至少一个编码块,所述重传控制信息包括受影响编码块 的指示信息,所述受影响编码块为所述至少一个传输块中的至少一个编码块。
该控制信息、受影响编码块和受影响编码块的指示信息的具体内容和传输方法可以参考前述实施例中的相关描述。
S505:终端设备接收该控制信息,并根据重传控制信息中的受影响编码块的指示信息确定受影响编码块。
终端设备解析该受影响编码块的指示信息的方法可以参考前述实施例中的相关描述。
S506:无线接入网设备向终端设备发送重传的受影响编码块,终端设备接收该重传的编码块,并使用该重传的编码块做数据恢复。
终端设备直接使用重传的编码块,不做缓存合并。
另一个实施例中,该受影响编码块的指示信息也可以不被包括在该控制信息中,比如该控制信息是承载在下行控制信道中,且该控制信息用于调度上述至少一个传输块,而该受影响编码块的指示信息可以是用独立的控制信道来承载,即独立于该控制信息因此也独立于上述下行控制信道。
本实施例中,受影响编码块的指示信息只存在于重传调度的情况下,即对于初传调度不进行该受影响编码块的指示信息的指示。一般的,URLLC很可能是在eMBB的控制信息和数据信息开始传输后才对eMBB进行打孔,即从中间打孔,而基站在调度eMBB的下行数据时还无法预测到会在中途受到URLLC突发业务的打孔。
对于重传调度下的受影响编码块的指示信息的设计,优选的可以复用控制信息中的MCS字段,采用其他指示方式也不做限定,比如使用新增比特或扰码,或者复用现在的除MCS字段之外的HARQ进程号指示字段等。下面对复用控制信息中的MCS字段的实施例进行描述。表1所示的为当前MCS字段的解析规则,可以看到,当前MCS字段为5个比特表示32种状态,其中状态索引0-28分别表示29种MCS级别且用于载荷索引的查询,而MCS索引29至31这3个状态主要用于重传调度时来变更调制阶数。此外,对于初传调度,MCS索引0-28和控制信息中的时频资源分配字段联合起来用于确定载荷大小。而对于重传调度,由于载荷要与初传时保持一致,而当前重传TB所占的时频资源在控制信息中有专门的字段来指示,因此对于重传调度,至少MCS索引0-28是冗余的,MCS索引29至31也只是起到重传时变更调制阶数的作用,而一般来说重传变更调制阶数的需求不大,因此也可以算作冗余。
因此,如果所述至少一个传输块为HARQ重传,所述受影响编码块的指示信息包括所述控制信息中的调制编码指示字段中的部分状态或全部状态,所述调制编码指示字段在所述至少一个传输块在HARQ初传时用于指示所述终端设备对于所述至少一个传输块在HARQ初传时的调制编码方式。

参考图11,本发明数据传输方法的另一个实施例,包含:
S1101:无线接入网设备向终端设备发送控制信息和受影响编码块的指示信息,所述控制信息用于所述无线接入网设备调度所述终端设备的至少一个传输块,所述至少一个传输块中的每个传输块中包括至少一个编码块,所述受影响编码块为所述至少一个传输块中的至少一个编码块;
该传输块、控制信息、受影响编码块和受影响编码块的指示信息的内容及传输方式参考上述实施例的相关描述。
S1102:终端设备接收无线接入网设备发送的控制信息和受影响编码块的指示信息。
S1103:无线接入网设备向终端设备至少发送至少一个传输块中除所述受影响编码块之外的至少一个编码块。
终端设备根据所述控制信息接收所述至少一个传输块;
S1104:所述终端设备根据所述受影响编码块的指示信息确定所述受影响编码块。
应该理解的是,步骤1103与步骤1104之间并没有严格的时间先后。
S1105:所述终端设备向所述无线接入网设备发送第一指示信息,所述第一指示信息指示第二编码块是否被正确接收,所述第二编码块为所述至少一个编码块中除所述受影响编码块之外的编码块,所述第一指示信息包含的比特数少于所述第二编码块的数量。
进一步的,无线接入网设备接收所述终端设备发送的第一指示信息。
一个实施例中,如果所述第二编码块被全部正确接收,则所述终端设备向所述无线接入网设备发送一个N比特的确认信息(ACK);如果至少一个第二编码块未被正确接收,则所述终端设备向所述无线接入网设备发送一个N比特的不确认信息(NACK)。其中,N为比第二编码块的数量小的正整数。
一个实施例中,第一指示信息包含的比特数少于第二编码块的数量。具体的,考虑到每个第二编码块都分别反馈确认或不确认比特的开销较大,且很可能多个编码块是否会被正确接收会有一定的相关性,因此可以考虑对第二编码块的数量对应的确认或不确认比特的开销进行压缩,比如采用部分编码块的确认或不确认信息的绑定反馈等方案。例如,有16个第二编码块,可以以8个编码块为一组,此时只需要反馈2个确认或不确认比特。
另一个实施例中,第一指示信息的比特数为一,所述终端设备向所述无线接入网设备发送第一指示信息,包括:如果所述第二编码块被全部正确接收,则所述终端设备向所述无线接入网设备发送一个确认比特,如果至少一个第二编码块未被正确接收,则所述终端设备向所述无线接入网设备发送一个不确认比特。
本实施例中,终端设备对一个TB中的受影响编码块和其他编码块(即第二编码块)是否被正确接收分别做反馈。在一种实现方式中,终端设备可以分别向无线接入网设备发送第一指示信息和第二指示信息,其中第一指示信息用来指示第二编码块是否被正确接收,第二指示信息用来指示受影响编码块是否被正确接收。可选的,与第一指示信息的绑定反馈类似,也可以采用类似的方案用于第二指示信息的发送,即所述第二指示信息包含的比特数少于所述受影响编码块的数量。另一个实现方式中,终端设备可以仅向无线接入网设备发送第一指示信息,不向无线接入网设备发送所述受影响编码块是否被正确接收的指示信息。由于受影响编码块未被正确接收的概率较大,可以默认为NACK而不做显性的反馈,以节约信令。
一个实施例中,如果所述受影响编码块被全部正确接收,则所述终端设备向所述无线接入网设备发送一个N比特的确认信息(ACK);如果至少一个受影响编码块未被正确接收,则所述终端设备向所述无线接入网设备发送一个N比特的不确认信息(NACK)。其中,N为比受影响编码块的数量小的正整数。
另一个实施例中,第二指示信息的比特数为一,所述终端设备向所述无线接入网设备发送第二指示信息,包括:如果所述受影响编码块被全部正确接收,则所述终端设备向所述无线接入网设备发送一个确认比特,如果至少一个受影响编码块未被正确接收,则所述终端设备向所述无线接入网设备发送一个不确认比特。
可选的,该方法还包括:无线接入网设备接收第一指示信息,并根据第一指示信息 确定是否对第二编码块进行重传。具体的,如果第一指示信息为确认信息(ACK),则不需要对第二编码块进行重传;如果第一指示信息为不确认信息(NACK),则对第二编码块进行重传。
可选的,该方法还包括:无线接入网设备接收第二指示信息,并根据第二指示信息确定是否对受影响编码块进行重传。具体的,如果第二指示信息为确认信息(ACK),则不需要对受影响编码块进行重传;如果第二指示信息为不确认信息(NACK),则对受影响编码块进行重传。
一个实施例中,无线接入网设备接收第一指示信息和第二指示信息,并根据第一指示信息和第二指示信息分别确认是否对第二编码块和受影响编码块进行重传。
另一个实施例中,无线接入网设备仅接收第一指示信息,并根据第一指示信息确定是否对受影响编码块进行重传。无线接入网设备不接收第二指示信息,对于受影响编码块默认为不确认信息并对受影响编码块做重传。由于受影响编码块未被正确接收的概率较大,可以默认为NACK而不做显性的反馈,以节约信令。
可选的,该方法还包括:
S1106:终端设备根据所述控制信息以及确定的所述受影响编码块接收所述至少一个传输块。
该步骤的具体实现可以参考上述图2中的步骤S204的相关描述。
可选的,该方法还包括:
终端设备接收无线接入网设备重发的第二编码块中未被正确接收的编码块;或
终端设备接收无线接入网设备重发的受影响编码块以及第二编码块中未被正确接收的编码块。
当前的ACK/NACK反馈是基于TB来做的,即只要TB中的至少一个CB未被正确接收,UE就会针对该TB反馈一个比特的NACK。基站无法知道该TB中的哪个或哪几个CB未被终端设备正确接收,尤其考虑到未被打孔的CB也可能由于信道衰落等原则造成未被接收正确。因此基站只能选择对整个TB进行重传。
而实施例针对URLLC对eMBB进行打孔的场景,被打孔的CB有很大概率上是无法被正确接收的,而不同于之前的是,哪个CB不会被正确接收是信道随机性带来的。因此,把受打孔影响CB与未受打孔影响CB进行区分处理,分别进行ACK/NACK反馈。例如,一个TB有8个CB,假设其中6个CB未被打孔,记为CB1至CB6,另外2个CB被打孔,记为CB7和CB8。可选的,终端设备针对该TB上报2个比特,其中1个比特针对CB7和CB8,由于基本上一定不会被正确接收,因此该比特基本为NACK;而假设CB1至CB6都被接收正确,则反馈1个比特为ACK,如果CB1至CB6至少有一个CB未被正确接收,则反馈1个比特NACK。可选的,终端设备还可以不针对受影响CB进行ACK/NACK反馈,而只针对其他CB进行反馈,即不针对CB7和CB8进行ACK/NACK反馈,因为基本上一定不会被正确接收;而只需要针对CB1至CB6进行1个比特的ACK/NACK反馈。
应该理解的是,上述图2、5、6对应的方法实施例与图11对应的方法实施例可以相互结合。例如,图2、5、6对应的方法实施例,还可以包含步骤S1108:所述终端设备向所述无线接入网设备发送第一指示信息,所述第一指示信息指示第二编码块是否被 正确接收,所述第二编码块为所述至少一个编码块中除所述受影响编码块之外的编码块,所述第一指示信息包含的比特数少于所述第二编码块的数量。或者,图2、5、6对应的方法实施例,还可以包含步骤S1109:终端设备可以分别向无线接入网设备发送第一指示信息和第二指示信息,其中第一指示信息用来指示第二编码块是否被正确接收,第二指示信息用来指示受影响编码块是否被正确接收。其中步骤S1108与步骤S1109的具体实现可以参考上述图11中的步骤S1105的相关描述。又如,图11对应的方法实施例,还可以包括步骤S1106:终端设备根据所述控制信息以及确定的所述受影响编码块接收所述至少一个传输块。
对应于上述方法,本发明提供一种终端设备,该终端设备可以应用于无线系统中的出现时间长度较短的突发干扰的场景,该终端设备可以执行上述方法实施例中的各个步骤。

该控制信息、受影响编码块和受影响编码块的指示信息的具体内容和传输方法可以参考前述实施例中的相关描述。
该第一指示信息和第二指示信息的具体内容和传输方法可以参考前述实施例中的相关描述。
参考图15,另一个实施例中,该无线接入网设备包括:
发送器1501,用于向终端设备发送控制信息和受影响编码块的指示信息,所述控制信息用于所述无线接入网设备调度所述终端设备的至少一个传输块,所述至少一个传输块中的每个传输块中包括至少一个编码块,所述受影响编码块为所述至少一个传输块中的至少一个编码块;向终端设备至少发送至少一个传输块中除所述受影响编码块之外的至少一个编码块;

该控制信息、受影响编码块和受影响编码块的指示信息的具体内容和传输方法可以参考前述实施例中的相关描述。
该第一指示信息和第二指示信息的具体内容和传输方法可以参考前述实施例中的相关描述。
另一个实施例中,为了解决部分CB打孔造成全部TB都重传的低效问题,再考虑到CB级的确认或不确认信息的上行发送开销较大的问题,本发明提供如下实施例,基于的假设是受影响CB很大程度会使得终端设备无法正确接收,且未受影响的CB被错误接收的概率不高,本实施例采用部分编码块的重传来解决上述重传效率并兼顾上行发送的开销。 参考图16,本发明提供的一种数据传输方法的一个实施例,可以用于无线接入网设备,该方法包括:
S1601:无线接入网设备向终端设备发送传输块,所述传输块中包括至少两个编码块;
其中,传输块以及编码块的具体内容可以参考前述实施例中的相关描述。
S1602:所述无线接入网设备接收所述终端设备发送的针对所述传输块的不确认信息,所述不确认信息用于指示所述终端设备未正确接收所述传输块;
其中,终端设备如果未能正确接收上述传输块中的所有编码块,则该终端设备会针对上述传输块向该无线接入网设备反馈1个不确认比特,这里可以基于现有LTE系统中的传输块级别的确认或不确认信息的反馈,而非基于编码块级别的确认或不确认信息的反馈。
需要说明的是,该传输块中的部分编码块可能由于被其他紧急业务打孔或者受到突发的干扰,而导致终端设备很大概率的无法对该部分编码块进行正确接收。该部分编码块可以包括前述实施例中描述的受影响编码块,与之相关的内容可以参考前述实施例中的相关描述。
相比之下,该传输块中除该部分编码块之外的其他编码块有较大概率会被终端设备所正确接收,而只有较小概率由于信道条件较差而导致被错误接收。
S1603:所述无线接入网设备向所述终端设备发送所述传输块中的部分编码块;
具体的,考虑到无线接入网设备向终端设备在步骤S1601中发送的传输块中的部分编码块受到突发干扰甚至被紧急业务所打孔,因此该部分编码块有极大概率无法被终端设备所正确接收。而其他未被影响的编码块虽然也可能由于信道条件较差而导致被错误接收,但这个事件发生的概率一般不是很大。因此,接收到终端设备针对该传输块反馈的不确认信息之后,或者甚至无线接入网设备在接收到终端设备针对该传输块反馈的确认或不确认信息之前(这意味着步骤S1602可以是可选的,或者至少不必须发生在步骤S1603之前),为了提升HARQ重传效率进而提升系统吞吐量,无线接入网设备可以向终端设备发送该传输块中的该部分编码块,而不重传该传输块中除该部分编码块之外的其他编码块,即无线接入网设备暂且假设该其他编码块已经被终端设备所正确接收。
S1604:所述无线接入网设备接收所述终端设备发送的针对所述传输块的确认或不确认信息,所述确认信息用于指示所述终端设备已经正确接收所述传输块中的所有编码块。
具体的,即使步骤S1603中无线接入网设备只重传了该传输块中的部分编码块,但无线接入网设备接收以及终端设备发送确认或不确认信息是针对整个传输块中的所有编码块的,主要原因是因为无线接入网设备尚未能确定终端设备针对该传输块中除该部分编码块之外的其他编码块是否被终端设备所正确接收。具体包括如下几种情况:
如果终端设备还是无法正确接收无线接入网设备重传的部分编码块,则终端设备会向无线接入网设备反馈不确认信息;
如果终端设备正确接收了无线接入网设备重传的部分编码块,且如果终端设备也已经正确接收了无线接入网设备在上述步骤S1601中发送的该传输块中除该部分编码块之外的其他编码块,则终端设备会向无线接入网设备反馈确认信息;
如果终端设备正确接收了无线接入网设备重传的部分编码块,但如果终端设备没有正确接收无线接入网设备在上述步骤S1601中发送的该传输块中除该部分编码块之外的其他编码块中的至少一个,则终端设备会向无线接入网设备反馈不确认信息。
为了解决部分CB打孔造成全部TB都重传的低效问题,再考虑到CB级的确认或不确认信息的上行反馈开销较大的问题,本发明提供的上述实施例,基于的假设是受影响CB很大程度会使得终端设备无法正确接收,且未受影响的CB被错误接收的概率不高,本实施例采用部分编码块的重传来解决上述重传效率并兼顾上行反馈的开销。
基于上述的数据传输方法,可选的,所述无线接入网设备向所述终端设备发送所述传输块时使用的HARQ进程号,与所述无线接入网设备向所述终端设备发送所述传输块中的部分编码块时使用的HARQ进程号相同。
具体的,由于针对步骤S1603中的该部分传输块的重传对应的确认或不缺认信息的反馈是针对整个传输块中的所有编码块的,因此步骤S1603中发送该部分编码块时使用的HARQ进程号,与步骤S1601中发送整个传输块时使用的HARQ进程号相同。该HARQ进程号可以是显示的被包括在调度上述传输块或部分编码块的控制信息中;也可以是隐示的被无线接入网设备和终端设备所确定,比如HARQ进程号可以与资源对应,该资源可以包括时间资源、频率资源和空间资源中的至少一种。具体的确定HARQ进程号的方式不做限定,只要能保证上述两个步骤中各自使用的HARQ进程号相同即可,即需要使得无线接入网设备和终端设备一致的认为两个步骤对应于相同的进程号,这样才能使得传输块与反馈信息的对应关系一致。
基于上述的数据传输方法,可选的,所述无线接入网设备向所述终端设备发送第一调度信息,所述第一调度信息用于向所述终端设备指示所述部分编码块的传输信息,所述部分编码块的传输信息包括是否为部分编码块传输和/或所述部分编码块的索引。
应理解,现有LTE系统中的HARQ重传需要重传整个传输块中的所有编码块,因此终端设备会默认该规则,因此不需要额外通知终端设备具体的哪些编码块被重传。而如本发明的步骤S1603所述,无线接入网设备向终端设备重传部分编码块,这不同于现有LTE系统中的HARQ重传机制,因此需要通知终端设备部分编码块的传输信息,具体可以包括当前的HARQ重传是否为部分编码块传输和/或所述部分编码块的索引。
如果部分编码块的传输信息包括是否为部分编码块传输,则需要指示终端设备当前的HARQ重传为部分编码块传输还是传统LTE的整个传输块的重传,该第一调度信息可以承载在步骤S1603中的调度部分编码块的控制信息中。此外,如果指示终端设备当前为部分编码块的重传传输,那么还需要向终端设备指示具体哪些编码块为上述部分编码块,比如部分编码块的编码块索引或编码块组的索引。具体的第一调度信息的指示方法都不做限定,比如可以通过控制信息中的显示比特指示,比如利用新增比特或复用现有的比特(比如MCS字段的全部或部分状态),也可以为控制信息的不同加扰方式来指示,也可以根据发送控制信道和/或数据信道的资源位置来隐示指示,该数据信道为承载上述传输块或部分编码块的信道,或者是上述显示和隐示的方法结合来指示。
如果部分编码块的传输信息包括哪些编码块为上述部分编码块,比如部分编码块的编码块索引或编码块组的索引,此时可以包括或不包括上述是否为部分编码块传输的信 息。具体的第一调度信息的指示方式都不做限定,可以参考上述实施例中的描述。

所述无线接入网设备接收所述终端设备发送的针对所述传输块的不确认信息之前,包括:所述无线接入网设备向所述终端设备发送第二调度信息,所述第二调度信息用于向所述终端设备指示所述部分编码块的索引;该第二调度信息即为上述提到的步骤S1601中的调度传输块的控制信息,具体的指示方法如上所述,在此不再赘述。
