背景技术
随着无线通信技术的发展,每个基站(Base Station,BS)需要支持数以万计用户设备(User Equipment,UE)的连接。以竞争式免调度(Contention-Based Grant-Free,CBGF)随机接入(Random Access)传输方案为例,基站无需对发送数据的UE事先进行调度和资源分配,也不能预先知道哪些UE有数据发送需求,这样就存在多个UE使用相同时频资源(Time and Frequency Resource)进行传输的可能性。为了基站能够在接收检测过程中区分不同UE,发送数据的UE将从系统提供的随机接入资源集合(如扩频序列、导频序列等)中随机选取一个资源(也称为标签(signature))进行数据发送。
由于基站没有对UE进行调度,因此需要针对数据包是否成功接收向每个UE反馈应答信号(Acknowledgement signaling),而一个基站需要同时服务成千上万个UE,若给每个被服务的UE都反馈1比特应答信号,则需反馈成千上万个比特应答信号。这样的反馈开销过大,导致频谱资源的浪费。

本申请实施例中涉及的用户设备,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。用户设备也可以是连接到无线调制解调器的其他处理设备。用户设备可以通过无线接入网(radio access network,RAN)与一个或多个核心网进行通信。用户设备也可以称为无线终端、订户单元(subscriber unit)、订户站(subscriber station),移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点(access point)、远程终端(remote terminal)、接入终端(access terminal)、用户终端(user terminal)、用户代理(user agent)。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。例如,用户设备还可以是个人通信业务(personal communication service,PCS)电话、无绳电话、会话发起协议(session initiation protocol,SIP)话机、无线本地环路(wireless local loop,WLL)站、个人数字助理(personal digital assistant,PDA)等设备。常见的用户设备例如包括: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,但本申请实施例不限于此。
本申请实施例中所涉及的基站,可以是全球移动通信系统(global system for mobile communication,GSM)或码分多址(code division multiple access,CDMA)中的基站(base transceiver station,BTS),也可以是宽带码分多址(wideband code division multiple access,WCDMA)中的基站(NodeB),还可以是LTE中的演进型基站(evolutional Node B,eNB或e-NodeB),还可以是新无线控制器(new radio controller,NR controller),可以是5G系统中的gNode B(gNB),可以是集中式网元(centralized unit),可以是新无线基站,可以是射频拉远模块,可以是微基站,可以是中继(relay),可以是分布式网元(distributed unit),可以是接收点(transmission reception point,TRP)或传输点(transmission point,TP)或者任何其它无线接入设备,但本申请实施例不限于此。网络设备可以覆盖1个或多个小区。
以在第三代合作伙伴计划(The 3rd Generation Partnership Project,3GPP)的5G技术规范(Technical Specification,TS)为例,UE的传输是由基站调度的,因此下行链路(Downlink)不需要反馈应答信号(Acknowledgement signaling)。在上行链路(Uplink),UE收到基站发送的传输块信号,使用传输块的循环冗余校验(Cyclic Redundancy Check,CRC)码来判断当前传输块是否正确接收。如果传输块通过CRC校验,则认为接收正确,UE在基站指定的时频资源上向基站反馈正确应答(positive Acknowledgement,ACK)状态(使用比特“1”表示);否则,UE向基站反馈错误应答(Negative Acknowledgement,NACK)状态(使用比特“0”表示)。根据不同场景的需要,应答状态可在5G标准定义的5种物理上行控制信道(Physical Uplink Control Channel,PUCCH)格式上传输。这5种格式分别是:PUCCH格式0、PUCCH格式1、PUCCH格式2、PUCCH格式3和PUCCH格式4,其中,PUCCH格式0~1用于传输1或2比特混合自动请求重传(Hybrid Automatic Repeat-reQuest,HARQ)应答(HARQ-ACK)信息和调度请求(Scheduling Request),PUCCH格式2~4用于传输信道状态信息(Channel State Information,CSI)报告或多比特的HARQ-ACK信息。
表1不同PUCCH格式占用的资源数量、传输比特数和用途的示例
表1示出了不同PUCCH格式下的负载比特数(payload size)、占用资源数和用途,其中OFDM表示正交频分复用(Orthogonal Frequency-Division Multiplexing),RB表示资源块(Resource Block),RE表示资源元素(Resource Element)。
PUCCH格式0和格式1的负载比特数不大于2,使用相移键控(Phase-Shift Keying)对负载进行调制后与序列相乘和扩频得到发送信号。PUCCH格式2~格式4则使用极化码信道编码和相移键控的方式得到发送信号。
从表1中可以看出,平均每传输1比特应答信号最少需要6个RE。对于未来大规模免调度系统,即使基站只服务1000个UE,也至少需要6000个RE进行应答信号反馈(约36个RB,每个RB有12*14=168个RE)。这将占用大量频谱资源。但实际上,同一时刻有数据传输的UE数量远远小于1000个(往往只有几十个),应答信号反馈效率较低。
基于此,本申请实施例提供了一种信息传输方法、通信设备、存储介质及程序产品,通过对正确或错误接收的传输块集合的信息进行压缩编码,使得多个正确或错误接收的UE的应答信号得到压缩,进而使得信道编码的输入比特数目大大减少甚至达到最小化(大部分情况下,只比最优压缩多1个比特),然后再进行信道编码和调制后发送出去;每个UE对接收到的应答信号进行解码和解压缩,提取对应的应答信号,进而实现节约频谱资源,提高数据传输效率的目的。
需要说明的是,在本申请的全部实施例中,表示大于或等于x的最小整数,表示小于或等于x的最大整数,表示x取y的组合数,log2x为对x取以2为底的对数,max表示取最大函数,mod表示取余函数,例如:0 mod 2=0,1 mod 2=1,3 mod 2=1,5 mod 3=2,或者mod(x,y)表示x除以y的余数,例如:mod(0,2)=0,mod(1,2)=1,mod(3,2)=1,mod(5,3)=2,后文中将不再赘述。

在另一些实施例中,根据填充比特序列长度Nfb,确定填充比特序列方式为:根据填充比特序列长度Nfb为0,确定填充比特序列为空序列。
填充比特序列的作用是使得在不同传输块子集合的传输块数目P下,反馈信息的长度都是相同的,这样第二节点不需要进行盲检来确定反馈信息的长度,从而降低译码复杂度。
在一些实施例中,根据传输块子集合的信息,直接确定压缩码字,其中,压缩码字为长度Nc的比特序列,传输块子集合的信息包括至少以下之一:传输块子集合的传输块数目最大值Pmax、传输块标识有序集合、传输块标识有序集合大小Na、传输块子集合的传输块标识集合、传输块子集合的传输块数目P、传输块差错图样a。
在一些实施例中,当传输块子集合的信息包括传输块子集合的传输块标识集合时,对传输块标识集合进 行压缩编码,确定压缩码字。

图4是本申请一实施例提供的传输块差错图样a的确定方法的流程图。如图4所示,传输块差错图样a通过下述步骤S3140、步骤S3141以及步骤S3142确定。在一些示例中,本实施例中传输块子集合的传输块标识集合为正确传输块标识集合。
步骤S3140:判断每个传输块标识有序集合中的元素是否属于正确传输块标识集合。
步骤S3141:如果传输块标识有序集合中的第i个元素属于正确传输块标识集合,则传输块差错图样的第i个比特a(i)=ack。
步骤S3142:如果传输块标识有序集合中的第i个元素不属于正确传输块标识集合,传输块差错图样的第i个比特a(i)=nack。
可以理解的是比特“ack”用于指示传输块的应答状态为正确应答ACK,比特“nack”用于指示传输块的应答状态为错误应答NACK,即,对于a(i)=ack,说明传输块标识有序集合中的第i个元素对应的传输块的应答状态为正确应答ACK,对于a(i)=nack,说明传输块标识有序集合中的第i个元素对应的传输块的应答状态为错误应答NACK。

步骤S3150:根据传输块差错图样的预设长度,得到与预设长度对应的传输块差错图样初始图样,其中,传输块差错图样初始图样中的每个元素对应错误应答比特。
在一些实施例中,设置传输块差错图样为长度Na且每个元素都是比特“nack”的序列,其中,Na为传输块标识有序集合大小。
步骤S3151:根据正确传输块集合,在传输块差错图样初始图样中,将序号等于所述正确传输块集合中元素的比特设置为正确应答比特。
步骤S3152:将传输块差错图样初始图样确定为传输块差错图样。
在一些实施例中,根据正确传输块集合BI={BI(1),B(2),...,BI(P)},对于i=1,2,...,P,将传输块差错图样初始图样中的第BI(i)个比特设置为a(BI(i))=ack,更新后的传输块差错图样初始图样为传输块差错图样,其中,P是正确传输块数目。
可以理解的是比特“ack”用于指示传输块的应答状态为正确应答ACK,比特“nack”用于指示传输块的应答状态为错误应答NACK,即,对于a(i)=ack,说明传输块标识有序集合中的第i个元素对应的传输块的应答状态为正确应答ACK,对于a(i)=nack,说明传输块标识有序集合中的第i个元素对应的传输块的应答状态为错误应答NACK。
在一些实施例中,比特“ack”为比特“1”,比特“nack”为比特“0”。
在一些实施例中,比特“ack”为比特“0”,比特“nack”为比特“1”。
在一些实施例中,根据传输块标识有序集合的大小与传输块子集合的传输块数目,确定压缩码字的长度。
在一些示例中,压缩码字的长度Nc等于其中,Na表示传输块标识有序集合的大小,P表示正确传输块数目。压缩码字是通过将个长度为Na的包含P个比特“ack”的比特序列映射到长度为的比特序列的算术编码得到的。
在一些实施例中,根据传输块差错图样的长度与正确传输块数目,确定压缩码字的长度。

在一些实施例中,如图3所示,所述“对传输块子集合的信息进行编码处理,得到反馈信息”还可以包括下述步骤S3200。
步骤S3200:将前缀码字、填充比特序列和压缩码字中的至少两个进行拼接,得到反馈信息。
如图10给出了一些由前缀码字、填充比特序列和压缩码字进行拼接,得到反馈信息的示意图。
记长度Np的前缀码字为[p1,p2,…,pNp],记长度Nfb的填充比特序列为[fb1,fb2,…,fbNfb],记长度Nc的压缩码字为c=[c1,c2,…,cNc]。
在一些实施例中,反馈信息f为[p1,p2,…,pNp,fb1,fb2,…,fbNfb,c1,c2,…,cNc],示意图如图10(a)。
在一些实施例中,反馈信息f为[p1,p2,…,pNp,c1,c2,…,cNc,fb1,fb2,…,fbNfb],示意图如图10(b)。
在一些实施例中,反馈信息f为[c1,c2,…,cNc,fb1,fb2,…,fbNfb,p1,p2,…,pNp],示意图如图10(c)。
在一些实施例中,反馈信息f为[fb1,fb2,…,fbNfb,c1,c2,…,cNc,p1,p2,…,pNp],示意图如图10(d)。
在一些实施例中,反馈信息f包括前缀码字。
在一些实施例中,反馈信息f包括压缩码字。
在一些实施例中,反馈信息f包括填充比特序列。
在一些实施例中,当填充比特序列的长度为0时,反馈信息f只包括前缀码字和压缩码字。在一些示例中,反馈信息f为[p1,p2,…,pNp,c1,c2,…,cNc],示意图如图10(e);或反馈信息f为[c1,c2,…,cNc,p1,p2,…,pNp],示意图如图10(f)。
在一些实施例中,当压缩码字的长度为0时,反馈信息f只包括前缀码字和填充比特序列。在一些示例中,反馈信息f为[p1,p2,…,pNp,fb1,fb2,…,fbNfb],示意图如图10(g);或反馈信息f为[fb1,fb2,…,fbNfb,p1,p2,…,pNp],示意图如图10(h)。
在一些实施例中,反馈信息f包括Pmax-P+1个比特用于指示传输块子集合的传输块数目P。
在一些实施例中,反馈信息f包括Pmax-P+1个比特的前缀码字。
在一些实施例中,反馈信息f包括长的填充比特序列。
在一些实施例中,反馈信息f包括长的填充比特序列,其中,Nf是反馈信息f的长度。

步骤S4000:发送反馈信息给至少一个第二节点。
在一些实施例中,第一节点发送反馈信息给一个或多个第二节点序列,这些反馈信息能够表征至少一个第二节点发送的传输块在第一节点的接收情况。
上述实施例提供的信息传输方法,当时,能够使得反馈信息的长度最多只比最优值多1个比特,即信道编码的输入比特数最多只比最优值多1个比特,进而实现节约频谱资源,提高数据传输效率的目 的。即使在的情况下,上述实施例一般也只比最小化长度多2或3个比特,并且具有低解码复杂度的特点(线性复杂度)。
在一些实施例中,传输块子集合为正确传输块集合,当第一节点没有正确接收的传输块,正确传输块标识集合为空集时,即P=0时,第一节点确定反馈信息f的长度Nf=0,即反馈信息f为空序列。第一节点确定包含为空序列的反馈信息f的信号为空信号,即第一节点确定包含反馈信息f的信号为零功率信号。
上述实施例提供的信息传输方法中由于第一节点发送零功率信号,使得能量开销降低,而第二节点序列中的一个第二节点对包含反馈信息f的信号(即零功率信号)接收不会成功,因此第二节点序列中的一个第二节点可以判断反馈信息为错误应答NACK。
在一些实施例中,对反馈信息进行信道编码,得到第一编码序列。
需要说明的是,信道编码可以是但不限于,极化编码(polar coding)、低密度奇偶校验编码(low-density parity check coding)、卷积编码(convolutional coding)、turbo编码(turbo coding)、RM码(Reed-Muller code)、RS码(Reed-Solomon code)、BCH码(Bose-Chaudhuri-Hocquenghem code)、级联编码(concatenated code)、循环码(cyclic code)、分组编码(block coding)、汉明编码(hamming code)、哥雷码(Golay code)、重复编码(repetition coding)、单奇偶校验码(single-parity-check code)、循环冗余校验码(cyclic redundancy check code)、叠加编码(superposition coding)、稀疏叠加编码(sparse superposition coding)、稀疏回归编码(sparse regression coding)、格编码(lattice coding)、代数几何码(algebraic geometric code)、Goppa码(Goppa code)、极化调整卷积码(Polarization-Adjusted Convolutional Codes)、预变换极化码(Pre-transformed Polar Codes)、奇偶校验极化码(Parity-Check Polar Codes)。
示例1

在本示例中,正确传输块数目最大值Pmax=3由基站配置。正确传输块标识集合为传输块集合中正确接收的传输块所包括的用户标识的集合。在本示例中,基站根据包含传输块集合B的信号确定了正确传输块标识集合为空集Φ,即,正确传输块数目P=0,进而基站根据正确传输块标识集合为空集Φ(或者正确传输块数目P=0)确定反馈信息f的长度为Nf=0且反馈信息f为空序列,与之对应的,基站确定包含反馈信息f的信号为零功率信号。
随后基站发送包含反馈信息f的零功率信号给终端序列SN(1),SN(2),SN(3),SN(4)。终端序列SN(1),SN(2),SN(3),SN(4)接收包含反馈信息f的零功率信号,本领域技术人员可以理解,对于t=1,2,3,4,终端SN(t)解码失败,确定传输块b(t)的应答为错误应答NACK。

本示例提供的信息传输方法,通过将正确传输块标识集合BI转换为传输块错误图样a,并且通过算术编码得到压缩码字c,通过正确传输块数目P的大小得到不同长度的前缀码,并通过添加不同长度的填充比特,使得反馈信息f,使得反馈信息f的长度不随正确传输块标识集合BI的大小而改变,可以降低译码的复杂度。 需要说明的是,虽然本示例中反馈信息f只比传输块错误图样a长度少1,但实际应用中,传输块错误图样a的长度Na很大,反馈信息f将比传输块错误图样a的长度要短。例如,当Na=100,Pmax=4时,反馈信息f的长度Nf为远小于Na=100的长度,而且只比下面的最优压缩长度多一个比特但是译码简单(与传输块错误图样a的长度成线性关系):
因此,在相同资源的情况下,本示例提供的方案相比直接传输传输块错误图样a的信道编码码率要低,从而使终端可以使用更低的接收信噪比,增强覆盖。
