本申请主张在2017年7月14日在中国提交的中国专利申请号No.201710576847.8的优先权,其全部内容通过引用包含于此。
技术领域
本公开文本实施例涉及通信技术领域,尤其涉及一种码块分割方法、终端、基站及计算机可读存储介质。
背景技术
3GPP(3rd Generation Partnership Project,第三代合作伙伴计划)使用LDPC(Low Density Parity Check Code,低密度奇偶校验码)用于5G(第五代移动通信技术的简称)NR(New Radio,新无线)的增强移动宽带(eMBB,Enhanced Mobile Broadband)应用场景。
LDPC通过对基础图(base graph)使用提升方法得到支持特定信息长度和码率的校验矩阵,从而进行编译码。采用一个针对较大信息块长度设计的base graph会损失短信息块LDPC的性能,而且还会降低短信息块的latency(延迟),这特别不利于URLLC(超高可靠与低延迟的通信)场景的低时延要求。所以一些公司提出希望采用多个base graph,不同的base graph可以支持的信息长度和码率也不同。
为了对性能与复杂度进行折衷,3GPP决定NR中可以使用具有两个base graph的LDPC编码方案。两个base graph,其中大的base graph大小为46×68列,其中前22列对应信息位,最低码率为1/3;而小的base graph大小为42×52列,最低码率为1/5。与大的base graph不同,小的base graph为了提高译码性能,降低译码时延,3GPP目前的结论是:当信息比特K>640时,base graph图中前10列对映信息位。当信息比特560<K≤640时,base graph的前9列对映信息位。当信息比特192<K≤560时,base graph的前8列对映信息位。当信息比特40<K≤192时,base graph的前6列对映信息位。
根据LTE(Long Term Evolution,长期演进)协议,基站和终端是通过获得下行控制信息(DCI,Downlink Control Information)中的调试编码方案(MCS,Modulation Coding Scheme)信息,查询存储的MCS表格获得传输块大小(TBs,Transport Block size)和目标R的值,然后根据LTE-Turbo码的最大信息块长度Kmax=6144进行码块分割,目标使得各个码块分段尽可能大且近似相等。具体思想如下:确定好TB(传输块)的大小后,如果TB的大小小于Kmax,将TB分为一个码块;若TB的大小大于Kmax,将TB的长度B除以(Kmax-L)得到码块个数
Figure PCTCN2018093333-appb-000001
其中在LTE协议中L为24比特CRC(Cyclic Redundancy Check,循环冗余校验);再根据码块个数C与TB的长度B与CRC的个数L,选择补零最少的Turbo码(Turbo Code)交织长度,完成码块分割过程。
然而,对于LDPC来说有两个base graph。由于存在两个最大信息块长度,所以码块的分割方法无法完全重用LTE中的码块分割设计,因此,亟需一种新的码块分割方案。

在本实施例中,可以通过码率识别的方式确定采用第一预设信息比特最大长度进行码块分割还是采用第二预设信息比特最大长度进行码块分割,例如:由于第一基础图的最低码率可能只有1/3,对于小区边沿用户,若码率低于1/3,通过采用本实施例的方法可以充分利用码率为1/5对应的第二基础图所对应于第二预设信息比特最大长度进行码块分割,提高系统性能。
下面结合两种具体的方法介绍本公开文本实施例中的码块分割的方法的流程:
方法一:
基站通过信令指示base graph的类型,若信令指示采用base graph#1,则基站或者终端采用第一预设信息比特最大长度(以下简称Kmax1)进行码块分割,将传输块以Kmax1为上限分割为一个或多个近似相等分段。若信令指示采用base graph#2,则基站或者终端采用第二预设信息比特最大长度(以下简称Kmax2)进行码块分割,将传输块以Kmax2为上限分割为一个或多个近似相等分段。
具体场景:基站采用1比特的动态信令在DCI中指示base graph的类型,例如DCI中base graph指示字段用0表示base graph#1,用1表示base graph#2。第一预设信息比特最大长度Kmax1=8448bits,第二预设信息比特最大长度Kmax2=2560bits。如TBsize=50000bits,若base graph字段值为0,则整个TB根据Kmax1=8448进行分段,假定CRC个数为16比特,则整个TB可以分为
Figure PCTCN2018093333-appb-000002
段,各段长度尽可能一致,如最多长度差1bit。
如若base graph字段值为1,则整个TB根据Kmax2=2560进行分段,仍然假定CRC个数为16比特,则整个TB可以分为
Figure PCTCN2018093333-appb-000003
段,各段长度也尽可能一致,例如长度之差最多为1bit。
需要说明的而是,上述base graph可以利用动态信令通知,当然也可以利用静态,半静态信令通知的方式。
方法二:
首先判断码率值(终端根据基站指示的信令信息如MCS,TBsize,分配的资源大小来判断码率,而基站则不需要),如果码率值R大于码率预设值R0,则将整个TB根据第一预设信息比特最大长度(以下简称Kmax1)进行码块分割,将传输块以Kmax1为上限分割为多个近似相等分段。例如分成的码块个数C=min C’,C’为正整数,且C’>=TBsize/(Kmax1-L),其中L为采用的CRC比特的长度,各个信息比特分段的长度尽可能相等。
若码率值R小于等于码率预设值R1,则将整个TB根据第二预设信息比特最大长度Kmax2进行码块分割,将传输块以Kmax2为上限分割为一个或多个近似相等分段,其中R0大于R1。
具体场景:假设第一预设信息比特最大长度Kmax1=8448bits,第二预设信息比特最大长度Kmax2=2560bits。假定TBsize=30000bits。若基站确定 的传输的码率值高于R0=1/3,则整个TB根据Kmax1=8448进行分段,假定CRC个数为16比特则整个TB可以分为
Figure PCTCN2018093333-appb-000004
段,各段长度尽可能一致,例如长度之差最多为1bit。若基站确定的传输码率值低于R1=1/5,则整个TB根据Kmax1=2560进行分段,假定CRC个数为16比特则整个TB可以分为
Figure PCTCN2018093333-appb-000005
段,各段长度尽可能一致,例如长度之差最多为1bit。
需要说明的是,上述R0=1/3仅是一个例子不排除其它值,上述R1=1/5仅是一个例子不排除其它值。
可选地,确定码率值的方法可以是:根据实际传输的TBsize与调度的资源大小,根据调制方式具体的计算出每次传输的码率值。
或者,根据指示信息(例如该指示信息可以是MCS Index)确定实际传输码率,这样避免了复杂的计算。以LTE的MCS为例:
表:Modulation and TBS index table(调试以及传输块索引对应关系表格,简称MSC表格)
Figure PCTCN2018093333-appb-000006
Figure PCTCN2018093333-appb-000007
上述MCS表格的每一行事实上代表了一个不同的码率,见3GPP文稿R1-081638,但是MCS表格隐含的码率只是目标值与实际传输的码率并不完全相同,但可以满足码块分割对码率的要求,利用MCS表格隐含码率来识别不同码率来实现码块分割是一种简单高效的方式。
