Definitions

  • the present invention relates to the field of communications, and more particularly to a method of transmitting feedback information, a user equipment, and an access device.
  • Hybrid Automatic Repeat Request is a technology that combines Forward Error Correction (FEC) and Automatic Repeat Request (ARQ) methods. By adding redundant information, FEC enables the receiver to correct a portion of the error, thereby reducing the number of retransmissions. For errors that FEC cannot correct, the receiving end requests the sender to resend the data through the ARQ mechanism.
  • the receiving end uses an error detection code, usually a CRC check, to detect if the received data packet is in error. If there is no error, send a positive acknowledgment (ACK); if there is an error, the receiver will drop the data packet and send a negative acknowledgment (NACK) to the sender. After receiving the NACK, the sender will resend the same. data.

Description

一种传输反馈信息的方法、用户设备和接入设备 技术领域
本发明涉及通信领域,并且更具体地,涉及一种传输反馈信息的方法、用户设备和接入设备。
背景技术
混合式自动重传请求(Hybrid Automatic Repeat Request,HARQ)是一种结合前向纠错(Forward Error Correction,FEC)与自动重复请求(Automatic Repeat Request,ARQ)方法的技术。FEC通过添加冗余信息,使得接收端能够纠正一部分错误,从而减少重传的次数。对于FEC无法纠正的错误,接收端会通过ARQ机制请求发送端重发数据。接收端使用检错码,通常为CRC校验,来检测接收的数据包是否出错。如果无错,则发送一个肯定的确认(ACK);如果出错,则接收端会丢弃数据包,并发送一个否定的确认(NACK)给发送端,发送端收到NACK后,会重发相同的数据。
载波聚合(Carrier Aggregation,CA)是将2个或更多的成员载波(Component Carrier,CC)聚合在一起传输数据以支持更大的传输带宽。在CA场景下,通常只通过一个主载波来反馈多个聚合的成员载波的HARQ反馈信息,HARQ反馈信息的比特数由配置的可以聚合的载波个数和传输(Transmission Mode,TM)模式来确定,当调度的载波数小于配置的可以聚合的载波数或调度的码字(CodeWord,CW)小于TM模式最大CW时,需要在HARQ反馈信息中填充一些冗余比特信息,这样,填充的信息会造成有效传输HARQ反馈信息的性能下降。

具体实施方式
下面将结合本发明实施例中的附图,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做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。
本发明的技术方案,可以应用于各种通信系统,例如:全球移动通讯系统(GSM,Global System of Mobile communication),码分多址(CDMA,Code Division Multiple Access)系统,宽带码分多址(WCDMA,Wideband Code Division Multiple Access Wireless),通用分组无线业务(GPRS,General Packet Radio Service),长期演进(LTE,Long Term Evolution)的频分双工(FDD,Frequency Division Duplex)或时分双工(TDD,Time Division Duplex)系统等。
用户设备(UE,User Equipment),也可称之为移动终端(Mobile Terminal)、移动用户设备等,可以经无线接入网(例如,RAN,Radio Access Network)与一个或多个核心网进行通信,用户设备可以是移动终端,如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机,例如,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。
接入设备,可以是GSM或CDMA中的接入设备,也可以是WCDMA中的接入设备,还可以是LTE中的接入设备,本发明并不限定。
图1示出了根据本发明实施例的传输反馈信息的方法1000的示意性流程图,该方法1000由用户设备执行,该方法1000包括:
S1100,用户设备接收接入设备发送的调度指示信息,该调度指示信息包括调度累积数和调度总数,该调度累积数和该调度总数用于确定该接入设备为该用户设备调度的载波或调度的码字的个数;
S1200,该用户设备向该接入设备发送HARQ反馈信息,该HARQ反馈信息用于指示在调度的载波或调度的码字上是否正确接收数据,其中,该HARQ反馈信息的比特数由调度的载波或调度的码字的个数确定。
在本发明实施例中,UE接收接入设备发送调度指示信息,该调度指示信息包括调度累积数和调度总数,该调度累积数和该调度总数用于确定该接入设备为该用户设备调度的载波或调度的码字的个数,可选地,该UE可以接收接入设备发送的下行指派信息(Downlink Assignment,DL Assignment)信息,例如,该DL Assignment包括下行控制信息格式(Downlink Control  Information fomat,DCI fomat)1/1A/1B/1D/2/2A/2B/2C/2D等,在该下行指派信息中包括该调度累积数和该调度总数。该UE根据该调度累积数和该调度总数确定该接入设备为该用户设备调度的载波或调度的码字的个数,然后该UE根据该调度的载波或该调度的码字的个数确定该HARQ反馈信息的比特数,这样,就不用在HARQ反馈信息中填充那些没有被调度的载波或调度的码字的HARQ反馈信息。然后该UE将根据该调度的载波或该调度的码字的个数确定的HARQ反馈信息发送给接入设备。例如,如果该接入设备为该用户设备配置的可用于传输数据的载波数为10,调度的载波个数为6,若每个载波的调度码字为1,那么可以确定HARQ反馈信息的比特数为6。可选地,该UE还可以根据该调度指示信息的接收情况确定哪些调度的载波上的下行数据传输失败,例如,如果该UE接收到的调度指示信息中包括的该调度总数为10,该UE收到8个调度的载波的调度指示信息的话,可以确定有2个调度的载波的调度指示信息传输失败,该UE可以根据该调度指示信息中包括的调度累积数确定哪个调度的载波或调度的码字上数据接收失败,然后该UE可以给这两个调度的载波的HARQ反馈信息填充NACK即可。
因此,本发明实施例的传输反馈信息的方法,能够根据调度指示信息中包括的调度累积数和调度总数,确定接入设备为用户设备调度的载波或调度的码字的个数,然后根据该调度的载波或该调度的码字的个数确定HARQ反馈信息的比特数,从而不用填充没有调度的载波或没有调度的码字的HARQ反馈信息,因此提高了传输HARQ反馈信息的性能。
可选地,在本发明实施例中,该调度累积数为一个下行子帧上的第一载波累积数,该调度总数为该一个下行子帧上的第一载波总数,调度的载波的顺序和个数由该一个下行子帧上的第一载波累积数和该一个下行子帧上的第一载波总数确定,该HARQ反馈信息的比特数为该调度的载波的个数。
具体而言,例如,在FDD场景,或TDD上下行配比配置为0或6时,一个上行子帧对应一个下行子帧的HARQ反馈信息,此时反馈窗口M=1,该调度累积数可以为一个下行子帧上的第一载波累积数,该调度总数可以为该一个下行子帧上的第一载波总数,可选地,该一个下行子帧上的第一载波累积数和该一个下行子帧上的第一载波总数可以承载于下行指派信息中。该UE可以根据该一个下行子帧上的第一载波累积数和该一个下行子帧上的第一载波总数确定调度的载波的个数,进而根据调度的载波的个数可以确定 HARQ反馈信息的比特数。
例如,图2是FDD场景,或TDD反馈窗口M=1场景,在图2中,该UE接收的调度指示信息中包括的该调度累积数为一个下行子帧上的第一载波累积数,该调度总数为该下行子帧上的第一载波总数,如图2所示,该接入设备在该下行子帧上配置的可用的载波数为10个,载波号从CC1~CC10,实际调度的载波为1号、2号、4号、6号、9号和10号载波,UE接收接入设备发送的调度指示信息,该UE获取的该调度指示信息中包括的调度累积数和调度总数包括:1/6,2/6,4/6,5/6,那么该UE实际接收到4个载波的调度指示信息,从调度指示信息中的第一载波总数为6可以知道有6个调度的载波。因为该第一载波累积数为从1开始的循环累积数,根据第一载波累积数的连续性,判断第一载波累积数为3和6的调度的载波的调度指示信息丢失。在该下行子帧上,有的调度的载波调度了两个码字,有的调度的载波调度了一个码字,UE不知道丢失调度指示信息的载波对应几个码字,可选地,可以将针对两个调度码字的载波的HARQ反馈信息做空间绑定处理(也就是将两个码字的HARQ反馈信息进行与操作),这样对应该6个调度的载波的HARQ反馈信息的比特数就为调度的载波的个数,即为6比特,每1比特代表1个调度的载波的HARQ反馈信息。对于调度指示信息接收失败的调度的载波,HARQ反馈信息为NACK,其他调度的载波的HARQ反馈信息根据在该调度的载波上是否正确接收数据确定是反馈ACK或NACK,如果正确接收,反馈ACK;反之,反馈NACK。例如,第一载波累积数为3和6的载波的调度指示信息接收失败,反馈NACK;第一载波累积数为1、4和5的载波的调度指示信息接收成功,并且下行数据正确接收,反馈ACK;第一载波累积数为2的载波调度了两个码字,一个码字的下行数据正确接收,另一个码字的下行数据没有正确接收,将该两个码字的HARQ反馈信息做空间绑定处理,反馈NACK。可选地,在本发明实施例中,该HARQ反馈信息按照调度的载波频域顺序(也可以是载波序号,后面的实施例类似,这里不再赘述)依次排列其HARQ反馈信息。例如,然后按照第一载波累积数循环累积的顺序依次排列调度的载波的HARQ反馈信息。那么,该6个调度的载波的HARQ反馈信息可以为100110。另外,可选的解决不同调度载波调度码字不同的问题,还可以采用按照多数载波调度码字的方向统一反馈HARQ比特数的方法,例如,如果10个可用的载波中有8 个载波的TM模式对应的都是1个码字,另外2个载波对应2个码字,那么统一的结果就是每个载波反馈一个比特,2个码字的载波HARQ反馈信息做空间绑定;相反的如果8个载波对应的码字是2个码字,另外2个载波对应1个码字,那么对应1个码字的载波可以做部分填充,补足HARQ反馈信息的比特数。总之,解决不同调度的载波调度的码字不同的问题是要将各个载波的HARQ反馈信息的比特数统一到一个相同的值即可。如果没有特殊声明,后续举例均以所有2个码字的载波都进行空间绑定的解决方案为例。另外还需要注意的是,如果UE在该子帧上没有收到任何一个下行调度指示信息,则不向该接入设备反馈HARQ信息。该接入设备收不到HARQ反馈信息自然会对未成功接收的数据进行重新发送。
应理解,该一个下行子帧上的第一载波累积数为一个循环累积计数值,例如,如果该第一载波累积数占4比特的话,该第一载波累积数可以按照该下行子帧上的调度的载波的顺序从1到16循环累积计数,如果该第一载波累积数占6比特的话,该第一载波累积数可以按照该下行子帧上的调度的载波的顺序从1到64循环累积计数,该第一载波累积数也可以为2比特或5比特等,本发明对此不作限制,在该第一载波累积数为n比特时,该第一载波累积数顺序从1到2n循环累积;该一个下行子帧上的第一载波总数为该下行子帧上的调度的载波的个数,如果该第一载波总数占4比特的话,该第一载波总数可以简化为对16求模,同样地,如果该第一载波总数占6比特的话,该第一载波总数可以简化为对32求模,该第一载波总数也可以为2比特或5比特等,本发明对此不作限制,在该第一载波总数为n比特时,该第一载波累积数可以简化为对2n求余的余数。下面的关于调度累积数和调度总数的其他表现形式和该第一载波累积数和第一载波总数的实现原理类似,下面就不一一赘述了。
可选地,在本发明实施例中,该调度累积数为多个下行子帧上的第二载波累积数,该调度总数为该多个下行子帧上的第二载波总数,该调度的载波的顺序和个数由该多个下行子帧上的第二载波累积数和该多个下行子帧上的第二载波总数确定,该HARQ反馈信息的比特数为该调度的载波的个数。
例如,在TDD上下行配比配置为3时,上行子帧2对应3个下行子帧的HARQ反馈信息,即反馈窗口M=3,即此时一个上行子帧反馈3个下行子帧的HARQ反馈信息。在这种情况下,该调度累积数可以为多个下行子 帧上的第二载波累积数,该调度总数可以为该多个下行子帧上的第二载波总数,可选地,该多个下行子帧上的第二载波累积数和该多个下行子帧上的第二载波总数可以承载于下行指派信息中。该UE可以根据该多个下行子帧上的第二载波累积数和该多个下行子帧上的第二载波总数确定调度的载波的顺序和个数,进而确定调度的载波的个数为HARQ反馈信息的比特数。
应理解,该多个下行子帧上的第二载波累积数为一个循环累积计数值,该多个下行子帧中的第二个下行子帧上的调度的载波的第二载波累积数是在第一个下行子帧上的第二载波累积数的基础上进行累积,而不是重新从1开始累积,后面的下行子帧的第二载波累积数也都是在前面下行子帧的第二载波累积数的基础上进行累积。也就是说,该第二载波累积数是在整个多个下行子帧上进行累积计数;该多个下行子帧上的第二载波总数为该多个下行子帧上的调度的载波在该多个下行子帧上被调度次数之和,也可以理解为该多个下行子帧中的每个下行子帧上的调度的载波的个数之和,该调度的载波在该多个下行子帧上被调度一次就计入第二载波总数中,在3个下行子帧上被调度三次,按三次计入第二载波总数中。
还应理解,在反馈窗口M=1时,也就是一个上行子帧对应一个下行子帧时,该调度的载波的个数为该下行子帧上调度的载波的个数,也可以为调度的载波的次数,这两个值是相等的;在反馈窗口M>1时,也就是一个上行子帧对应多个下行子帧时,该调度的载波的个数为该多个下行子帧上载波被调度的总次数,也就是说,一个调度的载波在该多个下行子帧上被调度3次,该调度的载波的个数按3计数。
例如,图3是TDD M=3场景,在图3中,该UE接收的调度指示信息中包括的该调度累积数为3个下行子帧上的第二载波累积数,该调度总数为该多个下行子帧上的第二载波总数(该3个下行子帧包括子帧1、子帧2和子帧3),整个反馈窗口M内,该UE接收到的调度指示信息中包括的该调度累积数和该调度总数包括:1/11、2/11、5/11、6/11、7/11、10/11。由上述参数可以知道该第二载波总数为11,所以在该3个下行子帧上载波被调度了11次,也就是该3个下行子帧上的调度的载波的个数为11,那么该HARQ反馈信息的比特数也为11位。根据该第二载波累积数的连续性,可以知道第二载波累积数为3、4、8、9和11的调度的载波的调度指示信息接收失败,反馈NACK,第二载波累积数为6的调度的载波的调度指示信息接收成功, 但是下行数据接收失败,也反馈NACK。可选地,在本发明实施例中,该HARQ反馈信息可以为每个下行子帧先按照每个调度的载波的HARQ反馈信息的顺序排列,再按照每个下行子帧上的HARQ反馈信息顺序排列,也就是按照第二载波累积数循环累积的顺序依次排列调度的载波的HARQ反馈信息。这样,该11位的HARQ反馈信息可以为11001010010。
可选地,在本发明实施例中,该调度累积数为多个下行子帧上的第二载波累积数,该调度总数为该多个下行子帧中每个下行子帧上的第一载波总数,该调度的载波的顺序和个数由该多个下行子帧上的第二载波累积数和该多个下行子帧中每个下行子帧上的第一载波总数确定,该HARQ反馈信息的比特数为该调度的载波的个数。
具体而言,该调度累积数可以为多个下行子帧上的第二载波累积数,该调度总数可以为该多个下行子帧中每个下行子帧上的第一载波总数,可选地,该多个下行子帧上的第二载波累积数和该多个下行子帧中每个下行子帧上的第一载波总数可以承载于下行指派信息中。该UE可以根据该多个下行子帧上的第二载波累积数和该多个下行子帧中每个下行子帧上的第一载波总数确定调度的载波的顺序和个数,进而确定调度的载波的个数为HARQ反馈信息的比特数。
应理解,该多个下行子帧上的第二载波累积数为一个循环累积计数值,同上面的实施例中的定义,这里不再赘述,该多个下行子帧中的每个下行子帧上的第一载波总数为该多个下行子帧中的每个下行子帧上的调度的载波的个数。例如,该多个下行子帧中的第一个下行子帧上如果有6个调度的载波,那么该第一个下行子帧上调度的载波的第一载波总数为6,该多个下行子帧中的第二个下行子帧上如果有3个调度的载波,那么该第二个下行子帧上的调度的载波的第一载波总数为3。也就是说,该多个下行子帧中的每个下行子帧上的第一载波总数是针对每个下行子帧而言的。
例如,图4为TDD M=3场景,在图4中,该调度累积数为3个下行子帧上的第二载波累积数,该调度总数为该3个下行子帧中每个下行子帧上的第一载波总数(该3个下行子帧包括子帧1、子帧2和子帧3),每个下行子帧上配置的可用的载波数都为10。整个反馈窗口M内,该UE接收到的调度指示信息中包括的该调度累积数和该调度总数包括:1/3、2/3、5/5、6/5、7/5、10/3。由上述参数可知,子帧1上的第一载波总数为3,也就是子帧1 上的调度的载波的个数为3;子帧2上的第一载波总数为5,也就是子帧2上的调度的载波的个数为5;子帧3上的第一载波总数为3,也就是子帧3上调度的载波的个数为3,那么在该3个下行子帧上调度的载波的个数之和为11,从而HARQ反馈信息的比特数也为11位。子帧1上丢失第二载波累积数为3的调度的载波的调度指示信息,由于第二载波累积数是在整个3个子帧上保持连续性,所以子帧2上丢失第二载波累积数为4和8的调度的载波的调度指示信息,同理,子帧3上丢失第二载波累积数为9和11的调度的载波的调度指示信息。第二载波累积数为3、4、8、9和11的调度的载波的HARQ反馈信息为NACK,第二载波累积数为6的调度的载波的调度指示信息接收成功,但是下行数据接收失败,也反馈NACK。可选地,该HARQ反馈信息可以为每个下行子帧先按照每个调度的载波的HARQ反馈信息的顺序排列,再按照每个下行子帧上的HARQ反馈信息顺序排列,也就是按照第二载波累积数循环累积的顺序依次排列调度的载波的HARQ反馈信息。这样,该11位的HARQ反馈信息可以为11001010010。
可选地,在本发明实施例中,该调度累积数为该多个下行子帧上的第二载波累积数,该调度总数为该多个下行子帧中的第一子帧集合上的第三载波总数,其中,该第一子帧集合包括当前下行子帧和该当前下行子帧之前的下行子帧,该调度的载波的顺序和个数由该多个下行子帧上的第二载波累积数和该多个下行子帧中第一子帧集合上的第三载波总数确定,该HARQ反馈信息的比特数为该调度的载波的个数。
具体而言,调度累积数为该多个下行子帧上的第二载波累积数,该调度总数为该多个下行子帧中的第一子帧集合上的第三载波总数,例如,如果该多个下行子帧为3个下行子帧(包括子帧1、子帧2和子帧3),那么该子帧1上的第三载波总数为该子帧1上的调度的载波的个数;子帧2上的第三载波总数在子帧1的调度的载波的个数加上子帧2上的调度的载波的个数,如果在子帧1上的调度的载波的个数为3,子帧2上调度的载波的个数为5,那么子帧2上的第三载波累积数为8;同样的,如果子帧3上的调度的载波的个数为3,子帧3上的第三载波总数为子帧1、子帧2和子帧3上的调度的载波的个数的和,也就是子帧3上的第三载波总数为11。该多个下行子帧上的第二载波累积数同上面的实施例中的定义,这里不再赘述。该UE可以根据该多个下行子帧上的第二载波累积数和该多个下行子帧中的第一子帧 集合上的第三载波总数,确定调度的载波的顺序和个数,进而确定该调度的载波的个数为HARQ反馈信息的比特数。
例如,图5为TDD M=3场景,在图5中,该调度累积数为3个下行子帧上的第二载波累积数,该调度总数为该3个下行子帧中的第一子帧集合上的第三载波总数(该3个下行子帧包括子帧1、子帧2和子帧3),每个下行子帧上配置的可用的载波数都为10。整个反馈窗口M内,该UE接收到的调度指示信息中包括的该调度累积数和该调度总数包括:1/3、2/3、5/8、6/8、7/8、10/11。从参数定义可知,第三载波总数相等的调度指示信息对应的载波应该位于同一个下行子帧上,从上述参数可以判断,子帧1上的第二载波累积数为3的载波的调度指示信息接收失败,由于子帧2上的第二载波累积数是在子帧1的基础上累积的,所以子帧2上的第二载波累积数是从4开始累积的,那么可以确定子帧2上的第二载波累积数为4和8的载波的调度指示信息接收失败,根据子帧2上的载波的第三载波总数为8,可以知道子帧2上的调度的载波的个数为5;同理,可以确定子帧3上的第二载波累积数为9和11的载波的调度指示信息接收失败,子帧3上的调度的载波的个数为3,根据3个下行子帧上的调度的载波的个数可以确定HARQ反馈信息的比特数为11位,丢失调度指示信息的载波上反馈NACK,第二载波累积数为6的载波上的下行数据没有正确接收,也反馈NACK。可选地,该HARQ反馈信息可以为每个下行子帧先按照每个调度的载波的HARQ反馈信息的顺序排列,再按照每个下行子帧上的HARQ反馈信息顺序排列,也就是按照第二载波累积数循环累积的顺序依次排列调度的载波的HARQ反馈信息。那么,该11位HARQ反馈信息可以为11001010010。
可选地,在本发明实施例中,如果该多个子帧中的某个子帧上的调度的载波的调度指示信息都接收失败,那个该子帧上的HARQ反馈信息按照该子帧上的配置载波数填充。
可选地,在本发明实施例中,该调度累积数为多个下行子帧中每个下行子帧上的第一载波累积数,该调度总数为该多个下行子帧中每个下行子帧上的第一载波总数,该调度的载波的顺序和个数由该多个下行子帧中每个下行子帧上的第一载波累积数和该多个下行子帧中每个下行子帧上的第一载波总数确定,该HARQ反馈信息的比特数为该调度的载波的个数。
具体而言,该调度累积数为多个下行子帧中每个下行子帧上的第一载波 累积数,该调度总数为该多个下行子帧中每个下行子帧上的第一载波总数,该多个下行子帧中的每个下行子帧上的第一载波累积数和第一载波总数和前面实施例中的含义相同,这里不再赘述。该UE可以根据该多个下行子帧中每个下行子帧上的第一载波累积数和第一载波总数,确定该多个下行子帧上的调度的载波的顺序和个数,进而确定该调度的载波的个数为HARQ反馈信息的比特数。例如,如果该多个下行子帧为3个下行子帧(包括子帧1、子帧2和子帧3),那么该子帧1上的第一载波总数为该子帧1上的调度的载波的个数;该子帧2上的第一载波总数为该子帧2上的调度的载波的个数,该子帧3上的第一载波总数为该子帧3上的调度的载波的个数。如果在子帧1上的调度的载波的个数为3,子帧2上调度的载波的个数为5,子帧3上的调度的载波的个数为3,那么,该3个下行子帧上的调度的载波的个数为11,从而可以确定HARQ反馈信息的比特数也为11位。
下面结合图6对本发明实施例进行详细介绍,图6为TDD M=3场景,在图6中,该调度累积数为3个下行子帧中每个下行子帧上的第一载波累积数,该调度总数为该3个下行子帧中每个下行子帧上的第一载波总数(该3个下行子帧包括子帧1、子帧2和子帧3),每个下行子帧上配置的可用的载波数都为10。整个反馈窗口M内,该UE接收到的调度指示信息中包括的该调度累积数和该调度总数包括:1/3、2/3、2/5、3/5、4/5、2/3。第一载波总数相等的调度指示信息对应的载波应该位于同一个下行子帧上,从上述参数可知,子帧1上的第一载波累积数为3的载波的调度指示信息接收失败,子帧1上的第一载波总数为3,也就是说子帧1上的调度的载波的个数为3;因为子帧2上的第一载波累积数是从1开始累积的,所以在子帧2上的第一载波累积数为1和5的载波的调度指示信息接收失败,从子帧2上第一载波总数为5,可以知道子帧2上的调度的载波的个数为5;同理,可以确定子帧3上的第一载波累积数为1和3的载波的调度指示信息接收失败,子帧3上的调度的载波的个数为3。那么该3个下行子帧上的调度的载波的个数之和为11,从而可以确定HARQ反馈信息的比特数为11位,丢失调度指示信息的载波上反馈NACK,子帧2上第一载波累积数为3的载波上的下行数据没有正确接收,也反馈NACK。该HARQ反馈信息可以为每个下行子帧先按照每个调度的载波的HARQ反馈信息的顺序排列,再按照每个下行子帧上的HARQ反馈信息顺序排列,那么,该11位HARQ反馈信息可以为 11001010010。
可选地,该调度指示信息还可以包括多个下行子帧上的第一调度载波总数,该第一调度载波总数指示载波在该多个下行子帧上被调度的总次数,也就是该第一调度载波总数等于每个下行子帧上的第一载波总数之和。可选地,该多个下行子帧上的第一调度载波总数可以承载于上行指派信息UL Assignment中,所述UL Assignment包括DCI format中的DCI format 0/4,例如,可以通过利用现在的UL Assignment中的下行指派索引(Downlink Assignment Index,DAI)域来承载多个下行子帧上的第一调度载波总数,该多个下行子帧上的第一调度载波总数的作用可以用图4至图6中的任一个来说明,例如,在图4中,如果子帧3上的所有调度的载波的调度指示信息都接收失败,如果没有该多个下行子帧上的第一调度载波总数的话,UE会认为子帧3上没有调度的载波,如果有这个参数的话,该UE可以对比该多个下行子帧上的第一调度载波总数与子帧1和子帧2上的第一载波总数,如果前一个参数大于后面两个参数之和,那么说明子帧3上是有调度的载波的,这个差值就是子帧3上的第一载波总数。例如,根据该多个下行子帧上的第一调度载波总数为11,而子帧1上的第一载波总数为3,子帧2上的第一载波总数为5,那么可以确定子帧3上的第一载波总数为3。那么在该3个下行子帧上调度的载波个数之和就变成11了,那么相应的HARQ反馈信息比特数也就变成11位而不是8位了。因此,该多个下行子帧上的第一调度载波总数可以用来对多个下行子帧上调度的载波的个数进行校验,使得UE能够获知该多个子帧上的实际的调度的载波的个数。
因此,本发明实施例的传输反馈信息的方法,能够根据调度指示信息中包括的调度累积数和调度总数,确定接入设备为用户设备调度的载波的个数,然后根据该调度的载波的个数确定HARQ反馈信息的比特数,从而就不用填充没有调度的载波的HARQ反馈信息,因此提高了传输HARQ反馈信息的性能。
在本发明实施例中,该调度累积数为一个下行子帧上的第一码字累积数,该调度总数为该一个下行子帧上的第一码字总数,调度的码字的顺序和个数由该一个下行子帧上的第一码字累积数和该一个下行子帧上的第一码字总数确定,该HARQ反馈信息的为该调度的码字的个数。
具体而言,该调度累积数为一个下行子帧上的第一码字累积数,该调度 总数为该一个下行子帧上的第一码字总数,可选地,该一个下行子帧上的第一码字累积数和该一个下行子帧上的第一码字总数可以承载于下行指派信息中。该UE可以根据该一个下行子帧上的第一码字累积数和该一个下行子帧上的第一码字总数确定调度的码字的个数,进而根据调度的码字的个数可以确定HARQ反馈信息的比特数。
应理解,该一个下行子帧上的第一码字累积数为一个循环累积计数值,例如,如果该第一码字累积数占4比特的话,该第一码字累积数可以按照该下行子帧上的调度的码字的顺序从1到16循环累积计数,该一个下行子帧上的第一码字总数为该下行子帧上的调度的码字的个数。
例如,图7是FDD场景,或TDD M=1场景,在图7中,该UE接收的调度指示信息中包括的该调度累积数为一个下行子帧上的第一码字累积数,该调度总数为该下行子帧上的第一码字总数,如图7所示,UE接收接入设备发送的调度指示信息,该UE获取的该调度指示信息中包括的调度累积数和调度总数包括:1/10、3/10、6/10、8/10,从上述参数可以知道,该下行子帧上的第一码字总数为10,也就是该下行子帧上的调度的码字个数为10个。该UE可以从接收的接入设备发送的下行控制信息中确定第一码字累积数为3的调度的码字所属的载波调度了两个码字,由于属于同一个载波的两个调度的码字的调度指示信息要么是同时接收成功要么是同时接收失败,所以第一码字累积数为2的调度的码字的调度指示信息也是接收成功的。同样地,可以知道,第一码字累积数为8的调度的码字所属的载波也调度了两个码字,也就是第一码字累积数为7的码字的调度指示信息也是接收成功的。根据第一码字累积数的连续性,可以判断第一码字累积数为4、5、9和10的调度的码字的调度指示信息丢失。对于调度指示信息接收失败的调度的码字,HARQ反馈信息为NACK,其他调度的码字的HARQ反馈信息根据在该调度的码字上是否正确接收数据确定是反馈ACK或NACK,如果正确接收,反馈ACK;反之,反馈NACK。例如,第一码字累积数为4、5、9和10的码字的调度指示信息接收失败,反馈NACK;第一码字累积数为1、3、6、7和8的码字的调度指示信息接收成功,并且下行数据正确接收,反馈ACK;第一码字累积数为2的码字的下行数据没有正确接收,反馈NACK。可选地,可以按照调度的码字频域顺序依次排列其HARQ反馈信息。例如,可以按照第一码字累积数循环累积的顺序依次排列调度的码字的HARQ反馈信息。 那么,该10个调度的码字的HARQ反馈信息可以为1010011100。
可选地,在本发明实施例中,该调度累积数为多个下行子帧上的第二码字累积数,该调度总数为该多个下行子帧上的第二码字总数,该调度的码字的顺序和个数由该多个下行子帧上的第二码字累积数和该多个下行子帧上的第二码字总数确定,该HARQ反馈信息的比特数为该调度的码字的个数。
例如,在TDD M>1的情况下,该调度累积数可以为多个下行子帧上的第二码字累积数,该调度总数可以为该多个下行子帧上的第二码字总数,可选地,该多个下行子帧上的第二码字累积数和该多个下行子帧上的第二码字总数可以承载于下行指派信息中。该UE可以根据该多个下行子帧上的第二码字累积数和该多个下行子帧上的第二码字总数确定调度的码字的个数,进而确定调度的码字的个数为HARQ反馈信息的比特数。
应理解,该多个下行子帧上的第二码字累积数和第二载波累积数的含义类似,也为一个循环累积计数值,区别在于该第二载波累积数是以调度的载波为单位进行累计,第二码字累积数是以调度的码字为单位进行累积。该多个下行子帧上的第二码字总数为该多个下行子帧上的调度的码字被调度的总次数,也可以理解为该多个下行子帧中的每个下行子帧上的调度的码字的个数之和,该调度的码字在该多个下行子帧中被调度一次就计入第二码字总数中,在3个下行子帧上被调度三次,按三次计入第二码字总数中。
还应理解,在反馈窗口M=1时,也就是一个上行子帧对应一个下行子帧时,该调度的码字的个数为该下行子帧上调度的码字的个数,也可以为调度的码字的次数,这两个值是相等的;在反馈窗口M>1时,也就是一个上行子帧对应多个下行子帧时,该调度的码字的个数为该多个下行子帧上码字被调度的总次数,也就是说,一个调度的码字在该多个下行子帧上被调度3次,该调度的码字的个数按3计数。
例如,图8是TDD M=3场景,在图8中,该UE接收的调度指示信息中包括的该调度累积数为3个下行子帧上的第二码字累积数,该调度总数为该多个下行子帧上的第二码字总数(该3个下行子帧包括子帧1、子帧2和子帧3),整个反馈窗口M内,该UE接收到的调度指示信息中包括的该调度累积数和该调度总数包括:2/19、4/19、10/19、11/19、12/19、17/19。由上述参数可以知道该第二码字总数为19,也就是说该3个下行子帧上的调度的码字的个数为19,那么该HARQ反馈信息的比特数也为19位。该UE可 以从接收的接入设备发送的下行控制信息中确定第一码字累积数为2、4、10和17的调度的码字所属的载波调度了两个码字,由于属于同一个载波的两个调度的码字的调度指示信息要么是同时接收成功要么是同时接收失败,因为第一码字累积数为2、4、10和17的调度的码字的调度指示信息接收成功,所以第一码字累积数为1、3、9和16的调度的码字的调度指示信息也是接收成功的。根据该第二码字累积数的连续性,可以知道第二码字累积数为5、6、7、8、13、14、15、18和19的调度的码字的调度指示信息接收失败,反馈NACK,第二码字累积数为11的调度的码字的调度指示信息接收成功,但是下行数据接收失败,也反馈NACK。可选地,在本发明实施例中,该HARQ反馈信息可以为每个下行子帧先按照每个调度的载波的HARQ反馈信息的顺序排列,再按照每个下行子帧上的HARQ反馈信息顺序排列,也就是按照第二码字累积数循环累积的顺序依次排列调度的码字的HARQ反馈信息。那么,该19位HARQ反馈信息可以为1111000001110001100。
可选地,在本发明实施例中,该调度累积数为多个下行子帧上的第二码字累积数,该调度总数为该多个下行子帧中每个下行子帧上的第一码字总数,该调度的码字的顺序和个数由该多个下行子帧上的第二码字累积数和该多个下行子帧中每个下行子帧上的第一码字总数确定,该HARQ反馈信息的比特数为该调度的码字的个数。
具体而言,该调度累积数可以为多个下行子帧上的第二码字累积数,该调度总数可以为该多个下行子帧中每个下行子帧上的第一码字总数,可选地,该多个下行子帧上的第二码字累积数和该多个下行子帧中每个下行子帧上的第一码字总数可以承载于下行指派信息中。该UE可以根据该多个下行子帧上的第二码字累积数和该多个下行子帧中每个下行子帧上的第一码字总数确定调度的码字的个数,进而确定调度的码字的个数为HARQ反馈信息的比特数。
应理解,该多个下行子帧上的第二码字累积数为一个循环累积计数值,同上面的实施例中的定义,这里不再赘述,该多个下行子帧中的每个下行子帧上的第一码字总数为该多个下行子帧中的每个下行子帧上的调度的码字的个数。例如,该多个下行子帧中的第一个下行子帧上如果有6个调度的码字,那么该第一个下行子帧上调度的码字的第一码字总数为6,该多个下行子帧中的第二个下行子帧上如果有3个调度的码字,那么该第二个下行子帧 上的调度的码字的第一码字总数为3。也就是说,该多个下行子帧中的每个下行子帧上的第一码字总数是针对每个下行子帧而言的。
例如,图9为TDD M=3场景,在图9中,该调度累积数为3个下行子帧上的第二码字累积数,该调度总数为该3个下行子帧中每个下行子帧上的第一码字总数(该3个下行子帧包括子帧1、子帧2和子帧3)。整个反馈窗口M内,该UE接收到的调度指示信息中包括的该调度累积数和该调度总数包括:2/6、、4/6、10/8、11/8、12/8、17/5。由上述参数可知,子帧1上的第一码字总数为6,也就是子帧1上的调度的码字的个数为6;子帧2上的第一码字总数为8,也就是子帧2上的调度的码字的个数为8;子帧3上的第一码字总数为5,也就是子帧3上调度的码字的个数为5,那么在该3个下行子帧上调度的码字的个数和为19,从而HARQ反馈信息的比特数也为19位。该UE可以从接收的接入设备发送的下行控制信息中确定第一码字累积数为2、4、10和17的调度的码字所属的载波调度了两个码字,由于属于同一个载波的两个调度的码字的调度指示信息要么是同时接收成功要么是同时接收失败,因为第一码字累积数为2、4、10和17的调度的码字的调度指示信息接收成功,所以第一码字累积数为1、3、9和16的调度的码字的调度指示信息也是接收成功的。结合上述推导,可以知道子帧1上丢失第二码字累积数为5和6的调度的码字的调度指示信息,由于第二码字累积数是在整个3个子帧上保持连续性,所以子帧2上丢失第二码字累积数为7、8、13和14的调度的码字的调度指示信息,同理,子帧3上丢失第二码字累积数为15、18和19的调度的码字的调度指示信息。上述丢失调度指示信息调度的码字的HARQ反馈信息为NACK,第二码字累积数为11的调度的码字的调度指示信息接收成功,但是下行数据接收失败,也反馈NACK。可选地,该HARQ反馈信息可以为每个下行子帧先按照每个调度的载波的HARQ反馈信息的顺序排列,再按照每个下行子帧上的HARQ反馈信息顺序排列,也就是按照第二码字累积数循环累积的顺序依次排列调度的码字的HARQ反馈信息。这样,该19位HARQ反馈信息可以为1111000001110001100。
可选地,在本发明实施例中,该调度累积数为该多个下行子帧上的第二码字累积数,该调度总数为该多个下行子帧中的第一子帧集合上的第三码字总数,其中,该第一子帧集合包括当前下行子帧和该当前下行子帧之前的下行子帧,该调度的码字的顺序和个数由该多个下行子帧上的第二码字累积数 和该多个下行子帧中第一子帧集合上的第三码字总数确定,该HARQ反馈信息的比特数为该调度的码字的个数。
具体而言,调度累积数为该多个下行子帧上的第二码字累积数,该调度总数为该多个下行子帧中的第一子帧集合上的第三码字总数,例如,如果该多个下行子帧为3个下行子帧(包括子帧1、子帧2和子帧3),那么该子帧1上的第三码字总数为该子帧1上的调度的码字的个数;子帧2上的第三码字总数在子帧1的调度的码字的个数加上子帧2上的调度的码字的个数,如果在子帧1上的调度的码字的个数为3,子帧2上调度的码字的个数为5,那么子帧2上的第三码字累积数为8;同样的,子帧3上的调度的码字的个数为3,子帧3上的第三码字总数为子帧1、子帧2和子帧3上的调度的码字的个数的和,也就是子帧3上的第三码字总数为11。该多个下行子帧上的第二码字累积数为一个循环累积计数值,同上面的实施例中的定义,这里不再赘述。该UE可以根据该多个下行子帧中第一子帧集合上的第三码字累积数和第三码字总数,确定调度的码字的个数,进而确定该调度的码字的个数为HARQ反馈信息的比特数。
例如,图10为TDD M=3场景,在图10中,该调度累积数为3个下行子帧上的第二码字累积数,该调度总数为该3个下行子帧中的第一子帧集合上的第三码字总数(该3个下行子帧包括子帧1、子帧2和子帧3)。整个反馈窗口M内,该UE接收到的调度指示信息中包括的该调度累积数和该调度总数包括:2/6、4/6、10/14、11/14、12/14、17/19。从参数的定义可知,第三码字总数相等的调度指示信息对应的码字应该位于同一个下行子帧上。该UE可以从接收的接入设备发送的下行控制信息中确定第一码字累积数为2、4、10和17的调度的码字所属的载波调度了两个码字,由于属于同一个载波的两个调度的码字的调度指示信息要么是同时接收成功要么是同时接收失败,因为第一码字累积数为2、4、10和17的调度的码字的调度指示信息接收成功,所以第一码字累积数为1、3、9和16的调度的码字的调度指示信息也是接收成功的。从上述参数可知,因为子帧1上的调度的码字的个数为6,所以子帧1上的第二码字累积数为5和6的码字的调度指示信息接收失败,由于子帧2上的第二码字累积数是在子帧1的基础上累积的,所以子帧2上的第二码字累积数是从7开始累积的,那么在子帧2上的第二码字累积数为7、8、13和14的码字的调度指示信息接收失败,根据子帧2上的码字 的第三码字总数为14,可以知道子帧2上的调度的码字的个数为8;同理,可以确定子帧3上的调度的码字的个数为5,子帧3上的第二码字累积数为15、18和19的码字的调度指示信息接收失败,根据3个下行子帧上的调度的码字的个数之和为19可以确定HARQ反馈信息的比特数为19位,丢失调度指示信息的码字上反馈NACK,第二码字累积数为6的码字上的下行数据没有正确接收,也反馈NACK。可选地,该HARQ反馈信息可以为每个下行子帧先按照每个调度的载波的HARQ反馈信息的顺序排列,再按照每个下行子帧上的HARQ反馈信息顺序排列,也就是按照第二码字累积数循环累积的顺序依次排列调度的码字的HARQ反馈信息。该19位HARQ反馈信息可以为1111000001110001100。
可选地,在本发明实施例中,该调度累积数为多个下行子帧中每个下行子帧上的第一码字累积数,该调度总数为该多个下行子帧中每个下行子帧上的第一码字总数,该调度的码字的顺序和个数由该多个下行子帧中每个下行子帧上的第一码字累积数和该多个下行子帧中每个下行子帧上的第一码字总数确定,该HARQ反馈信息的比特数为该调度的码字的个数。
具体而言,该调度累积数为多个下行子帧中每个下行子帧上的第一码字累积数,该调度总数为该多个下行子帧中每个下行子帧上的第一码字总数,该UE可以根据该多个下行子帧中每个下行子帧上的第一码字累积数和第一码字总数,确定该多个下行子帧上的调度的码字的顺序和个数,进而确定该调度的码字的个数为HARQ反馈信息的比特数。例如,如果该多个下行子帧为3个下行子帧(包括子帧1、子帧2和子帧3),那么该子帧1上的第一码字总数为该子帧1上的调度的码字的个数;该子帧2上的第一码字总数为该子帧2上的调度的码字的个数,该子帧3上的第一码字总数为该子帧3上的调度的码字的个数。如果在子帧1上的调度的码字的个数为3,子帧2上调度的码字的个数为5,子帧3上的调度的码字的个数为3,那么,该3个下行子帧上的调度的码字的个数为11,从而可以确定HARQ反馈信息的比特数也为11位。
下面结合图11对本发明实施例进行详细介绍,图11为TDD M=3场景,在图11中,该调度累积数为3个下行子帧中每个下行子帧上的第一码字累积数,该调度总数为该3个下行子帧中每个下行子帧上的第一码字总数(该3个下行子帧包括子帧1、子帧2和子帧3)。整个反馈窗口M内,该UE接 收到的调度指示信息中包括的该调度累积数和该调度总数包括:2/6、4/6、4/8、5/8、6/8、3/5。第一码字总数相等的调度指示信息对应的码字应该位于同一个下行子帧上,从上述参数可以知道,子帧1上的第一码字总数为6,也就是子帧1上的调度的码字的个数为6;子帧2上的第一码字总数为8,也就是子帧2上的调度的码字的个数为8;子帧3上的第一码字总数为5,也就是子帧3上调度的码字的个数为5,那么在该3个下行子帧上调度的码字的个数和为19,从而HARQ反馈信息的比特数也为19位。该UE可以从接收的接入设备发送的下行控制信息中确定子帧1上第一码字累积数为2和4的调度的码字所属的载波调度了两个码字,由于属于同一个载波的两个调度的码字的调度指示信息要么是同时接收成功要么是同时接收失败,因为第一码字累积数为2和4的调度的码字的调度指示信息接收成功,所以第一码字累积数为1和3的调度的码字的调度指示信息也是接收成功的;同样地,子帧2上第一码字累积数为4的调度的码字所属的载波也调度了两个码字,所以子帧2上第一码字累积数为3的调度的码字的调度指示信息也是接收成功的;同样的,子帧3上的第一码字累积数为3的调度的码字所属的载波也调度了两个码字,所以子帧3上第一码字累积数为2的调度的码字的调度指示信息也是接收成功的。从上述推导可知,子帧1上的第一码字累积数为5和6的码字的调度指示信息接收失败;因为子帧2上的第一码字累积数是从1开始累积的,所以在子帧2上的第一码字累积数为1、2、7和8的码字的调度指示信息接收失败;同理,可以确定子帧3上的第一码字累积数为1、4和5的码字的调度指示信息接收失败。丢失调度指示信息的码字上反馈NACK,子帧2上第一码字累积数为5的码字上的下行数据没有正确接收,也反馈NACK。可选地,该HARQ反馈信息可以为每个下行子帧先按照每个调度的载波的HARQ反馈信息的顺序排列,再按照每个下行子帧上的HARQ反馈信息顺序排列,那么,该19位HARQ反馈信息可以为1111000001110001100。
可选地,该调度指示信息还可以包括多个下行子帧上的第一调度码字总数,该第一调度码字总数指示码字在该多个下行子帧上被调度的总次数,也就是该第一调度码字总数等于每个下行子帧上的第一码字总数之和。可选地,该多个下行子帧上的第一调度码字总数可以承载于上行指派信息UL Assignment中,所述UL Assignment包括DCI format中的DCI format 0/4, 例如,可以通过利用现在的UL Assignment中的DAI域来承载多个下行子帧上的第一调度码字总数,该多个下行子帧上的第一调度码字总数的作用可以用图9至图11中的任一个来说明,例如,在图9中,如果子帧3上的所有调度的码字的调度指示信息都接收失败,如果没有该多个下行子帧上的第一调度码字总数的话,UE会认为子帧3上没有调度的码字,如果有这个参数的话,该UE可以对比该多个下行子帧上的第一调度码字总数与子帧1和子帧2上的第一码字总数,如果前一个参数大于后面两个参数之和,那么说明子帧3上是有调度的码字的,这个差值就是子帧3上的第一码字总数。例如,根据该多个下行子帧上的第一调度码字总数为19,而子帧1上的第一码字总数为6,子帧2上的第一码字总数为8,那么可以确定子帧3上的第一码字总数为5。那么在该3个下行子帧上调度的码字个数之和就变成19了,那么相应的HARQ反馈信息比特数也就变成19位而不是14位了。因此,该多个下行子帧上的第一调度码字总数可以用来对多个下行子帧上调度的码字的个数进行校验,使得UE能够获知该多个子帧上的实际的调度的码字的个数。
可选地,在本发明实施例中,该调度指示信息中还包括归属载波指示信息,该归属载波指示信息指示调度的码字归属的载波信息,如果两个调度码字对应同一个载波,他们的归属载波指示信息相同,那么可以对该两个调度码字的HARQ反馈信息做空间绑定处理,否则,分别反馈这两个调度的码字的HARQ反馈信息。可选地,可以在下行指派信息中新增域来承载该参数,或者利用该下行指派信息中现有的域来承载该参数。本发明对此不作限制。
因此,本发明实施例的传输反馈信息的方法,能够根据调度指示信息中包括的调度累积数和调度总数,确定调度的码字的个数,然后根据该调度的码字的个数确定该HARQ反馈信息的比特数,从而不用生成没有调度的码字的HARQ反馈信息,因此提高了传输HARQ反馈信息的性能。
应理解,在本发明实施例中,该调度累积数和该调度总数可以承载于下行指派信息中,例如,可以在下行指派信息新增域来承载该调度累积数和该调度总数,或者可以利用该现有的下行指派信息中TDD的DAI域来承载该调度累积数和该调度总数中的一个参数,再新增一个域来承载另一个参数。本发明对此不做限制。另外,在该调度指示信息包括多个下行子帧上的第一 调度载波总数时,该多个下行子帧上的第一调度载波总数可以承载于上行指派信息中,可选地,可以在上行指派信息新增域来承载该第一调度载波总数,也可以利用该现有TDD上行指派信息中的DAI域来承载该第一调度载波总数。新增域的大小由该调度累积数、调度总数和该第一调度载波总数的大小以及考虑到的连续错误概率情况对比特数的优化情况来决定。同样地,对于该多个下行子帧上的第一调度码字总数亦是如此,这里不再赘述。例如,如果该调度累积数最大为32,完整考虑需要新增5个比特的域来承载该调度累积数。优选的,考虑连续4个载波或码字被丢掉的可能性较低,那么可以只使用2个比特的域来承载该调度累积数,原始的调度累积数值X可以用2比特的Y=mod(X-1,4)+1的值来代替X的值,其中,mod(X-1,4)表示将X-1对4求模,即该调度累积数可以从1到4循环累积计数;以此类推,考虑连续8个载波或码字被丢掉的可能性较低,也可以用3比特的域来承载调度累积数,即原始的调度累积数值X可以用3比特的Y=mod(X-1,8)+1的值来代替X的值,即该调度累积数可以从1到8循环累积计数。
例如,图12中,该调度总数简化为原始的调度总数除以4的余数,该调度累积数简化为从1到4循环累积计数,该UE获取的该调度指示信息中包括的调度累积数和调度总数包括:1/2,2/2,4/2,1/2,那么该UE根据实际接收到4个调度的载波的调度指示信息,而第一载波总数为2,可以推断该第一载波总数为6。因为该第一载波累积数按照从1到4循环累积计数,根据第一载波累积数的连续性,可以判断第一载波累积数为3的调度的载波的调度指示信息丢失,加上这个丢失的调度的载波后一共5个调度的载波,所有UE判断最后一个调度的载波的调度指示信息也没有接收到,所以最后一个第一载波累积数为2的调度的载波的调度指示信息丢失。然后该UE给丢失调度指示信息的调度的载波反馈NACK。其他调度的载波的HARQ反馈信息根据在该调度的载波上是否接收到数据,确定反馈ACK或NACK。根据上述信息,可以确定该下行子帧上的调度的载波的HARQ反馈信息。
还应理解,本发明实施例仅以M=3为例进行描述,但本发明并不限于此,M还可以为其他值,例如M=2或M=4等,在M为其他值时,根据调度指示信息确定调度的载波或调度的码字的个数的方法类似,这里不再赘述。
因此,本发明实施例的传输反馈信息的方法,能够根据调度指示信息中包括的调度累积数和调度总数,确定调度的载波或调度的码字的个数,然后 根据该调度的载波或该调度的码字的个数确定该HARQ反馈信息的比特数,从而不用生成没有调度的载波或没有调度的码字的HARQ反馈信息,因此提高了传输HARQ反馈信息的性能。
上文结合图1至图12,从UE的角度介绍了根据本发明实施例的传输反馈信息的方法,下文从接入设备的角度对根据本发明实施例的传输反馈信息的方法进行介绍。
图13示出了根据本发明实施例的传输反馈信息的方法3000的示意性流程图,该方法3000可以由接入设备执行,该方法3000包括:
S3100,接入设备向用户设备UE发送调度指示信息,该调度指示信息包括调度累积数和调度总数,该调度累积数和该调度总数用于确定该接入设备为该用户设备调度的载波或调度的码字的个数;
S3200,该接入设备接收该UE发送的HARQ反馈信息,该HARQ反馈信息的比特数由该调度的载波或该调度的码字的个数确定。
具体而言,接入设备向用户设备发送调度指示信息,该调度指示信息包括调度累积数和调度总数,该调度累积数和该调度总数用于确定该接入设备为该用户设备调度的载波或调度的码字的个数;可选地,该接入设备可以向用户设备发送下行指派信息,在该下行指派信息中承载该调度累积数和调度总数,以便于该UE根据该调度累积数和该调度总数确定该接入设备为该用户设备调度的载波或调度的码字的个数,然后根据该调度的载波或该调度的码字的个数确定该HARQ反馈信息的比特数。该接入设备接收用户设备发送的HARQ反馈信息,该HARQ反馈信息的比特数是由该调度的载波或该调度的码字的个数确定的。
因此,本发明实施例的传输反馈信息的方法,能够通过向用户设备发送调度指示信息,使得用户设备能够根据该调度指示信息中包括的调度累积数和调度总数确定调度的载波或调度的码字的个数,然后根据该调度的载波或该调度的码字的个数确定HARQ反馈信息的比特数,从而不用填充没有调度的载波或调度的码字的HARQ反馈信息,因此提高了传输HARQ反馈信息的性能。
可选地,在本发明实施例中,接入设备可以通过在下行指派信息(UL Assignment)中新增域的方法来承载该调度累积数和该调度总数,或者可以利用下行指派信息中现有的域来承载该调度指示信息,接入设备也可以通过 其他下行控制信息承载该调度指示信息,本发明对此不作限制。例如,如果该下行指派信息中包括的调度指示信息为一个下行子帧上的第一载波累积数和第一载波总数,可以通过在下行指派信息中新增两个域的方式来承载该一个下行子帧上的第一载波累积数和第一载波总数,或者将现有的域进行复用来承载该一个下行子帧上的第一载波累积数和第一载波总数,本发明实施例对比不作限制。
可选地,在本发明实施例中,该调度累积数为一个下行子帧上的第一载波累积数,该调度总数为该一个下行子帧上的第一载波总数;或者,
该调度累积数为多个下行子帧上的第二载波累积数,该调度总数为该多个下行子帧上的第二载波总数;或者,
该调度累积数为多个下行子帧上的第二载波累积数,该调度总数为该多个下行子帧中每个下行子帧上的第一载波总数;或者,
该调度累积数为该多个下行子帧中的第一子帧集合上的第三载波累积数,该调度总数为该多个下行子帧中的第一子帧集合上的第三载波总数,其中,该第一子帧集合包括当前下行子帧和该当前下行子帧之前的下行子帧;或者,
该调度累积数为多个下行子帧中每个下行子帧上的第一载波累积数,该调度总数为该多个下行子帧中每个下行子帧上的第一载波总数。
具体而言,在该调度累积数为一个下行子帧上的第一载波累积数,该调度总数为该一个下行子帧上的第一载波总数时,该调度的载波的个数是由该一个下行子帧上的第一载波累积数和该一个下行子帧上的第一载波总数确定的,HARQ反馈信息的比特数又是由该调度的载波的个数确定的,也就是说每一位HARQ反馈信息代表一个调度的载波的HARQ反馈信息,该接入设备可以根据该HARQ反馈信息的内容确定哪些调度的载波上的数据接收失败,从而决定对该载波上的数据重新发送。例如,在M=1时,如果该接入设备接收的HARQ反馈信息100110,由于哪些载波被调度了该接入设备是知道的,每个调度的载波的HARQ反馈信息的排列顺序是由接入设备和UE预先配置好的。例如,该HARQ反馈信息100110是按照调度的载波的频域顺序依次排列的,所以该接入设备根据该HARQ反馈信息100110,就可以推断该下行子帧上按照频域顺序,第2、第3和第6个调度的载波的下行数据接收异常,需要重新发送。
同样地,在反馈窗口M>1时,该调度累积数可以为多个下行子帧上的第二载波累积数,该调度总数可以为该多个下行子帧上的第二载波总数;或者,
该调度累积数可以为多个下行子帧上的第二载波累积数,该调度总数可以为该多个下行子帧中每个下行子帧上的第一载波总数;或者,
该调度累积数可以为该多个下行子帧中的第一子帧集合上的第三载波累积数,该调度总数可以为该多个下行子帧中的第一子帧集合上的第三载波总数,其中,该第一子帧集合包括当前下行子帧和该当前下行子帧之前的下行子帧;或者,
该调度累积数可以为多个下行子帧中每个下行子帧上的第一载波累积数,该调度总数可以为该多个下行子帧中每个下行子帧上的第一载波总数。
该接入设备接收到的HARQ反馈信息是该多个下行子帧中的每个下行子帧上的调度的载波的HARQ反馈信息,可选地,该HARQ反馈信息是先按照每个下行子帧上的调度的载波的顺序再按照该多个下行子帧中每个下行子帧上的HARQ反馈信息顺序排列的。例如,在M=3时,如果该接入设备接收的HARQ反馈信息为11001010010,该HARQ反馈信息为3个下行子帧的调度的载波的HARQ反馈信息,接入设备知道子帧1上有3个调度的载波,所以可以确定该HARQ反馈信息中的前3比特为子帧1上的3个调度的载波的HARQ反馈信息,同样地,接入设备知道子帧2上有5个调度的载波,可以确定紧接着后面的5个比特为子帧2上5个调度的载波的HARQ反馈信息,最后3个比特为子帧3上的3个调度的载波的HARQ反馈信息,从而该接入设备可以确定哪些调度的载波上的HARQ反馈信息为NACK,从而可以确定该调度的载波上的下行数据需要重新发送。
在本发明实施例中,该调度指示信息还包括多个下行子帧上的第一调度载波总数,可选地,该第一调度载波总数可以承载于上行指派信息(Uplink Assignment,UP Assignment)信息中,也可以承载于其他下行控制信息中,本发明实施例对此不做限制。
可选地,该调度累积数为该一个下行子帧上的第一码字累积数,该调度总数为该一个下行子帧上的第一码字总数;或者,

该调度累积数为多个下行子帧上的第二码字累积数,该调度总数为该多个下行子帧中每个下行子帧上的第一码字总数;或者,
该调度累积数为该多个下行子帧中的第一子帧集合上的第三码字累积数,该调度总数为该多个下行子帧中的第一子帧集合上的第三码字总数,其中,该第一子帧集合包括当前下行子帧和该当前下行子帧之前的下行子帧;或者,
该调度累积数为多个下行子帧中每个下行子帧上的第一码字累积数,该调度总数为该多个下行子帧中每个下行子帧上的第一码字总数。
具体而言,在该调度累积数为一个下行子帧上的第一码字累积数,该调度总数为该一个下行子帧上的第一码字总数时,该调度的码字的个数是由该一个下行子帧上的第一码字累积数和该一个下行子帧上的第一码字总数确定的,HARQ反馈信息的比特数又是由该调度的码字的个数确定的,也就是说每一位HARQ反馈信息代表一个调度的码字的HARQ反馈信息,该接入设备可以根据该HARQ反馈信息的内容确定哪些调度的码字上的数据接收失败,从而决定对该码字上的数据重新发送。例如,在M=1时,如果该接入设备接收的HARQ反馈信息1010011100,由于哪些码字被调度了该接入设备是知道的,每个调度的码字的HARQ反馈信息的排列顺序是由接入设备和UE约定好的,例如,该HARQ反馈信息1010011100是按照调度的码字的频域顺序依次排列的,所以该接入设备根据该HARQ反馈信息1010011100,就可以推断该下行子帧上按照频域顺序,第2、3、4、8和9个调度码字的下行数据接收异常,需要重新发送。
同样地,在反馈窗口M>1时,该调度累积数可以为多个下行子帧上的第二码字累积数,该调度总数可以为该多个下行子帧上的第二码字总数;或者,
该调度累积数可以为多个下行子帧上的第二码字累积数,该调度总数可以为该多个下行子帧中每个下行子帧上的第一码字总数;或者,
该调度累积数可以为该多个下行子帧中的第一子帧集合上的第三码字累积数,该调度总数可以为该多个下行子帧中的第一子帧集合上的第三码字总数,其中,该第一子帧集合包括当前下行子帧和该当前下行子帧之前的下行子帧;或者,
该调度累积数可以为多个下行子帧中每个下行子帧上的第一码字累积 数,该调度总数可以为该多个下行子帧中每个下行子帧上的第一码字总数。
该接入设备接收到的HARQ反馈信息是该多个下行子帧中的每个下行子帧上的调度的码字的HARQ反馈信息,可选地,该HARQ反馈信息是先按照每个下行子帧上的调度的码字的顺序再按照该多个下行子帧中每个下行子帧上的HARQ反馈信息顺序排列的。例如,在M=3时,如果该接入设备接收的HARQ反馈信息为1111000001110001100,该HARQ反馈信息为3个下行子帧的调度的码字的HARQ反馈信息,接入设备知道子帧1上有6个调度的码字,所以可以确定该HARQ反馈信息中的前6比特为子帧1上的6个调度的码字的HARQ反馈信息,同样地,接入设备知道子帧2上有8个调度的码字,可以确定紧接着后面的8个比特为子帧2上8个调度的码字的HARQ反馈信息,最后5个比特为子帧3上的5个调度的码字的HARQ反馈信息,从而该接入设备可以确定哪些调度的码字上的HARQ反馈信息为NACK,从而可以确定该调度的载波上的下行数据需要重新发送。
因此,本发明实施例的传输反馈信息的方法,能够通过向用户设备发送调度指示信息,使得用户设备能够根据该调度指示信息中包括的调度累积数和调度总数确定调度的载波或调度的码字的个数,从而根据该调度的载波或该调度的码字的个数确定HARQ反馈信息的比特数,从而不用填充没有调度的载波或没有调度的码字的HARQ反馈信息,因此提高了传输HARQ反馈信息的性能。
