Abstract

本发明涉及通信技术领域,公开了一种传输、存储下行数据的方法、基站及终端,在该方案中,基站在每一次传输下行数据时,所采用的比特选择的方式,令任意一终端类型的终端对同一个码块的初始传输(或者重复传输)期望接收到的序列的长度和序列的起始点,与发送端确定的对同一个码块的要发送的序列的长度和序列的起始点相同,使终端可靠译码;若译码失败,则终端每次存储针对同一个码块的初始传输(或者重复传输)的序列的起始点,与发送端确定的对同一个码块的初始传输(或者重复传输)要发送的序列的起始点相同,避免了终端每次存储针对同一个码块的重传码块时,无法准确存储,进而无法准确译码的缺陷,因此,提高了终端的译码的准确度。

Description

一种传输、存储下行数据的方法、基站及终端 技术领域
本发明涉及通信技术领域,特别涉及一种传输、存储下行数据的方法、基站及终端。
背景技术
LTE(Long Term Evolution,长期演进)以及LTE-A(Long Term Evolution-Advanced,长期演进-高级版)标准中定义了终端(User Equipment,用户设备)类型,如终端类型1、终端类型2、……、终端类型10,不同的终端类型对应的上行能力和下行能力是不同的。
例如,终端类型1的下行能力包括:
1个TTI(Transmission Time Interval,传输时间间隔)内接收的最大下行共享信道DL-SCH传输块比特数为10296比特、1个传输间隔TTI内接收1个下行共享信道DL-SCH传输块的最大比特数为10296比特、总的软信道比特数Nsoft为250368比特,以及下行能支持的最大空分复用层数为1层。
终端类型1的上行能力包括:
1个传输间隔TTI内发送的最大上行共享信道UL-SCH传输块比特数为5160比特、1个传输间隔TTI内发送1个上行共享信道UL-SCH传输块的最大比特数为5160比特、上行不支持64QAM。
终端类型的下行能力中的总的软信道比特数Nsoft表征终端处理HARQ(Hybrid Automatic Repeat Request,混合自动请求重传)的能力,决定终端具有存储Nsoft这么多比特数的buffer(缓存)。每个并行下行HARQ进程所能占用的软信道比特数为Nsoft的一部分,对应的buffer用来缓存该HARQ进程对应的软信道比特。
在实际应用中,一个传输块在发送前先经过信道编码,如果一个传输块 太长(编码输入信息比特数超过6144)会被分成多个码块,每个码块经过1/3码率信道编码后除包含信息比特外,还包含冗余比特。当终端收到一个传输块的第一次传输时,终端尝试译码接收到的数据,如果这个传输块的数据译码成功,那么成功译码后的数据就交给高层进一步处理,如果这个传输块的数据未译码成功,那么终端将正在尝试译码的数据取代该HARQ进程对应的缓存中存储的数据;当终端收到的是传输块的重传时,那么传输块的重传数据会和当前在该HARQ进程对应的buffer中该传输块的数据进行合并,并对合并后的数据尝试译码,如果这个传输块的数据译码成功,那么成功译码后的数据就交给高层进一步处理;如果这个传输块的数据没有成功译码,那么终端将正在尝试译码的数据取代该HARQ进程对应的buffer中存储的数据。
一个传输块在发送前先经过信道编码,如果一个传输块太长会被分成多个码块,对应的码字的个数为C,即一个传输块分成C个码块,那么每个码块对应的软缓存的大小为Ncb=NIR/C,由于对于同一个传输块,数据重传时和该传输块的上次发送使用的冗余版本不同,因此,每个码块在发送前做速率匹配时要进行比特选择,然后采用选择的比特对码块进行发送。
目前,在传输一个下行传输块时,该下行传输块包括的每一个码块在发送时,采用公式一决定第r个码块对应的软缓存buffer的大小:
Figure PCTCN2015084817-appb-000001
其中,Ncb为一个码块的软缓存大小;
NIR为一个传输块的软缓存大小,采用公式二进行计算;
C为码块的数量;
Kw为第r个码块的虚拟循环缓存的长度;
Figure PCTCN2015084817-appb-000002
其中,KC为在载波聚合(Carrier Aggregation)时支持的最大载波的数量;如 果终端的终端类型为8,其中Nsoft=35982720,那么KC=5;如果终端的终端类型为6或7,其中Nsoft=3654144,并且终端的能力是下行支持最多不超过2层的空分复用传输,那么KC=2;除上述之外的其他的情况下,KC=1;
KMIMO为一个与配置的传输模式相关的参数,表征1个TTI内可以同时发送的传输块的数量;如果终端被配置成接收基于传输模式3、4、8、9,或10的PDSCH(Physical Downlink Shared channel,物理下行共享信道)发送数据,KMIMO=2;除此之外的情况,KMIMO=1;
MDL_HARQ为对每个服务小区中的终端的最大下行HARQ进程数;下行接收时,终端对于每个服务小区有一个HARQ实体来处理几个并行的HARQ进程,且每个下行HARQ进程对应一个HARQ进程ID。每个HARQ实体对应的最大下行HARQ进程数,在FDD(Frequency Division Duplex,频分双工)系统下最大为8;TDD(Time Division Duplex,时分双工)系统下最大的HARQ进程数与UL(Uplink,上行)/DL(Downlink,下行)配比有关,如UL/DL配比0时,最大HARQ进程数为4,UL/DL配比1时,最大HARQ进程数为7;UL/DL配比2时,最大HARQ进程数为10;UL/DL配比3时,最大HARQ进程数为9;UL/DL配比4时,最大HARQ进程数为12;UL/DL配比5时,最大HARQ进程数为15;UL/DL配比6时,最大HARQ进程数为6。除此之外,无论是FDD还是TDD系统下,终端还有一个额外的专用广播HARQ进程;
Mlimit为发送端在决定终端每个HARQ进程所能使用的buffer大小时使用的极限值;如终端在TDD UL/DL配比0时,最大HARQ进程数为4,那么,发送端在决定终端每个HARQ进程所能使用的buffer大小时按照4个HARQ进程数来计算;如终端在TDD UL/DL配比5时,最大HARQ进程数为15,那么,发送端在决定终端每个HARQ进程所能使用的buffer大小时按照8个HARQ进程数来计算。
但是,采用公式一选择下行数据对应的Ncb时,当发送广播数据(包含SI (System Information,系统信息)消息,RAR(Random Access Response,随机接入响应)消息,及Paging消息),会存在由于基站发送的信息序列和终端期望接收的信息序列不一致,而导致终端无法正确译码的缺陷,理由如下:
有些终端的Nsoft为25344,按照公式二计算得到NIR为3168比特(其中,假设KC=1、KMIMO=1、以FDD系统为例,MDL_HARQ=8),例如,当广播的传输块TB比特数为2216时,Kw=6816,C=1,因此,当下行数据是在PCH(Paging Channel,寻呼信道)上递送至物理层的数据,或者是在在关联RA(Random Access,随机接入)-RNTI(Radio Network Temporary Identifier,无线网络临时标识)的DL-SCH(Downlink Shared Channel,下行共享信道)上递送至物理层的数据,或者是在关联SI(System Information,系统信息)-RNTI的DL-SCH上递送至物理层的数据,基站进行比特选择时会选择参数
Figure PCTCN2015084817-appb-000003
对于终端类型1-10的终端,基站进行比特选择时会选择参数
Figure PCTCN2015084817-appb-000004
因此无论基站会选择哪个参数进行比特选择,发送广播,都会出现某些终端和基站的假设不一致的情况。例如,当基站选择参数Ncb=3168时,终端类型1-10的终端会按照参数Ncb=6816接收广播;如果基站选择参数Ncb=6816时,Nsoft为25344的终端会按照参数Ncb=3168接收广播。这种终端和基站的假设不一致的情况就会导致终端期望基站发送的信息比特不是基站实际发送的信息比特,因此,存在终端无法正确译码的缺陷。
