Abstract

本申请提供一种UCI-only场景中的通信方法,包括:接收用于调度PUSCH的下行控制信息,该PUSCH包含第一跳频资源和第二跳频资源,第一跳频资源的时域起始符号位于第二跳频资源的时域起始符号之前;在PUSCH上发送第一UCI,第一UCI包含HARQ-ACK、CSI-part1和CSI-part2中的至少一个;其中,第一跳频资源中预留RE上映射的编码比特数大于或等于第二跳频资源中预留RE上映射的编码比特数。上述方案减少了第二跳频资源中预留RE能够映射的编码比特数,从而增加了第二跳频资源中用于映射CSI-part1的RE的数量,解决了跳频传输UCI导致CSI-part1发送不完整的问题。

Description

通信方法和装置
本申请要求于2018年8月10日提交中国专利局、申请号为201810910306.9、申请名称为“通信方法和装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域,尤其涉及一种通信方法和装置。
背景技术
第五代(the 5th generation,5G)移动通信系统支持上行控制信息(uplink control information,UCI)在物理上行共享信道(physical uplink shared channel,PUSCH)上传输,并且存在只发送UCI不发送上行共享信道(uplink shared channel,UL-SCH)的场景,即,存在UCI-only场景。
在UCI-only场景中发送的UCI包括混合自动重传请求确认应答(hybrid automatic repeat request acknowledgement,HARQ-ACK)、信道状态信息第一部分(channel state information part 1,CSI-part1)和信道状态信息第二部分(CSI-part2),这三种信息对保护等级的要求按照上述顺序依次降低,因此,终端设备在将上述三种信息映射到资源上时,会按照信道估计质量的好坏依次将HARQ-ACK、CSI-part1和CSI-part2映射到PUSCH的可承载数据的资源元素(resource element,RE)上。
为了获得跳频增益,PUSCH可以在时域上分为前后两部分,该两部分分别称为第一跳(hop1)和第二跳(hop2),为了获得尽量大的跳频增益,hop1和hop2的频域资源一般相隔较远,至少不完全重叠。相应地,HARQ-ACK、CSI-part1和CSI-part2也会被按照预设的规则映射到hop1和hop2上,然而,被映射到跳频资源上的CSI-part1会出现信息发送不完整的现象,即,部分CSI-part1没有传输成功,这对UCI-only场景中通过跳频传输UCI的应用造成不利影响。
发明内容
本申请提供一种通信方法和装置,通过改变CSI-part1的映射规则,能够解决UCI-only场景中通过跳频传输UCI导致CSI-part1会出现信息发送不完整的问题。
第一方面,提供了一种通信方法,包括:接收下行控制信息,该下行控制信息用于调度PUSCH,PUSCH仅用于承载UCI,该PUSCH包含第一跳频资源和第二跳频资源,所述第一跳频资源的时域起始符号位于所述第二跳频资源的时域起始符号之前;在PUSCH上发送第一UCI,第一UCI包含HARQ-ACK、CSI-part1和CSI-part2中的至少一个;其中,第一跳频资源中的预留RE上映射的编码比特数为第一数值,第二跳频资源中的预留RE上映射的编码比特数为第二数值,第一数值不小于第二数值,第一跳频资源中的预留RE和第二跳频资源中的预留RE是为比特数不大于2的潜在HARQ-ACK传输预留的RE。 对于执行上述方法的设备的对侧设备来说,所述对侧设备可以相应的执行发送下行控制信息,并在所述PUSCH上接收第一UCI的步骤。这里需要说明的是,所述PUSCH包含第一跳频资源和第二跳频资源,是指,当网络设备指示的上行授权(UL grant)DCI的跳频标识字段使能该PUSCH做跳频时,PUSCH在第一跳和第二跳的时频域资源分别叫做第一跳频资源和第二跳频资源。为了进行区分,本申请中PUSCH的第一跳频资源和第二跳频资源有起始时序上的先后关系。另外,在PUSCH的一定数量的RE上映射的编码比特数的值,等于RE数量乘以所述PUSCH的传输层数再乘以所述PUSCH上潜在传输的UCI的调制阶数。
CSI-part1出现信息发送不完整的原因在于,CSI-part1映射在第二跳频资源上的编码比特数较少,也就是说,第二跳频资源上用于映射CSI-part1的RE数量较少,导致CSI-part1无法全部映射到第二跳频资源上,本申请提供的通信方案,相对于现有技术减少了第二跳频资源中预留RE能够映射的编码比特数,从而增加了第二跳频资源中用于映射CSI-part1的RE的数量,解决了UCI-only场景中通过跳频传输UCI导致CSI-part1出现信息发送不完整的问题。
可选地,所述方法还包括:确定第一编码比特数

是第一跳频资源中的预留RE和第二跳频资源中的预留RE上映射的编码比特数之和,其中,所述第一数值和所述第二数值均基于所述

确定。
上述“第一跳频资源中的预留RE和第二跳频资源中的预留RE上映射的编码比特数之和”指的是第一跳频资源中的预留RE和第二跳频资源中的预留RE能够映射的编码比特数之和,而不应被理解为第一跳频资源中的预留RE和第二跳频资源中的预留RE实际映射的编码比特数之和。

第一跳频资源上第一组连续的解调参考信号(demodulation reference signal,DMRS)符号之后能够用于承载数据的RE映射的编码比特数,以及,基于G ACK确定的第三数值。
若第一UCI中的HARQ-ACK在第一跳频资源上能够映射的编码比特数超过第一跳频资源的承载能力,则终端设备可以按照第一跳频资源的承载能力确定第一UCI中的HARQ-ACK在第一跳频资源上映射的编码比特数,反之,则终端设备可以按照第一UCI中的HARQ-ACK在第一跳频资源上能够映射的编码比特数(例如,

确定该HARQ-ACK在第一跳频资源上映射的编码比特数。
可选地,所述第一跳频资源上第一组连续的DMRS符号之后能够用于承载数据的RE 映射的编码比特数的值等于M 3·N L·Q m,其中M 3为所述第一跳频资源上第一组连续的DMRS符号之后能够用于承载数据的RE个数,N L为PUSCH的传输层数,Q m为第一UCI的调制阶数,上述第三数值为

其中,所述第一UCI中的HARQ-ACK的比特数不大于2。

具体实施方式
下面将结合附图,对本申请中的技术方案进行描述。
图1示出了一种适用本申请的通信系统。该通信系统包括网络设备和终端设备,网络设备与终端设备通过无线网络进行通信,当终端设备发送信息时,终端设备的无线通信模块可获取要通过信道发送至网络设备的信息比特,这些信息比特例如是终端设备的处理模块生成的、从其它设备接收的或者在终端设备的存储模块中保存的信息比特。
在本申请中,终端设备可称为接入终端、用户设备(user equipment,UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备以及5G通信系统中的用户设备。
网络设备可以是码分多址(code division multiple access,CDMA)系统中的基站(base transceiver station,BTS),也可以是宽带码分多址(wideband code division multiple access,WCDMA)系统中的基站(node B,NB),还可以是长期演进(long term evolution,LTE)系统中的演进型基站(evolutional node B,eNB),还可以是5G通信系统中的基站(gNB),上述基站仅是举例说明,网络设备还可以为中继站、接入点、车载设备、可穿戴设备以及其它类型的设备。
上述适用本申请的通信系统仅是举例说明,适用本申请的通信系统不限于此,例如,通信系统中包括的网络设备和终端设备的数量还可以是其它的数量。
为了便于理解本申请的技术方案,首先对本申请涉及的概念做简要介绍,以5G系统为例说明如下。
在UE通过PUSCH向gNB发送UCI的场景中,由于UE可能漏检下行控制信道(physical uplink control channel,PDCCH),从而对需要反馈的HARQ-ACK比特数的认知出现错误,即UE实际反馈的HARQ-ACK比特数比gNB调度其反馈的HARQ-ACK比特数少;进而还可能导致UE通过PUSCH发送的所有UCI都不能被gNB正确接收。为了避免CSI-part1受到UE少发送HARQ-ACK的影响,通信协议对UE通过PUSCH向gNB发送UCI的场景中定义了用于HARQ-ACK的预留RE(reserved RE for HARQ-ACK),即,预留RE。具体定义是:
(1)当HARQ-ACK信息比特数为0、1或2时,都按照HARQ-ACK信息比特数为2来生成预留RE。
(2)预留RE上不能发送保护等级要求较高的CSI-part1,因此HARQ-ACK在信息比特数不大于2时,其发送缺失不会对CSI-part1造成影响。
(3)预留RE上可以发送CSI-part2和UL-SCH(在UCI-only场景中只有发送CSI-part2的可能性)。
(4)如果有HARQ-ACK信息比特需要发送(即HARQ-ACK信息比特数为1或者2),则HARQ-ACK在预留RE上发送。此时相当于HARQ-ACK对已经映射在预留RE上的CSI-part2做了打孔。
为了获得跳频增益,PUSCH可以在时域上分为前后两部分,该两部分分别称为第一跳(hop1)和第二跳(hop2),hop1和hop2的频域资源相异。相应地,HARQ-ACK、CSI-part1和CSI-part2也会被按照预设的规则映射到hop1和hop2上。
上述映射规则可以通过图2直观的表示出来。如图2所示,CSI-part1只映射到非预留RE上;CSI-part2既有映射到预留RE的部分,也有映射到非预留RE的部分;如果有HARQ-ACK(即信息比特为1或2),则映射到预留RE上(相当于在已经映射了CSI-part2的编码比特的资源上进行打孔)。
对于PUSCH的跳频,有如下规定:
PUSCH符号数的跳频规则包含时隙(slot)内跳频,以及slot间跳频,具体为:
对于slot内跳频,hop1的符号数为PUSCH符号总数的一半且下取整,即
Figure PCTCN2019099037-appb-000050
hop2的符号数为PUSCH符号总数减去hop1符号数,即
Figure PCTCN2019099037-appb-000051
其中
Figure PCTCN2019099037-appb-000052
为PUSCH在一个slot内的符号总数。
对于slot间跳频,hop1和hop2以slot为单位在时间上划分。例如,slot号为偶数的为hop1,slot号为奇数的为hop2。
根据当前协议规定的PUSCH跳频情况下的解调参考信号(demodulation reference signal,DMRS)图样来看,slot内跳频可能出现的情况包括:hop1和hop2的可承载数据的符号数相等;或者,hop1比hop2的可承载数据的符号数少1;slot间跳频的情况下hop1和hop2可承载数据的符号数相等。
预留RE所映射的编码比特数的跳频拆分规则如下:
假设预留RE所映射的编码比特数为
Figure PCTCN2019099037-appb-000053
则hop1和hop2的预留RE所映射的编码比特数分别为
Figure PCTCN2019099037-appb-000054
Figure PCTCN2019099037-appb-000055
其中N L为PUSCH传输层数,Q m为PUSCH调制阶数。由式(1)和式(2)分别可知,
Figure PCTCN2019099037-appb-000056
Figure PCTCN2019099037-appb-000057
式(3)和式(4)中的等号都只有在
Figure PCTCN2019099037-appb-000058
可以整除(2·N L·Q m)时成立。
现有的标准规定,在UCI-only场景中,UCI各部分(HARQ-ACK、CSI-part1和CSI-part2)的编码比特数在跳频情况下也会按照一定规则拆分。在讲拆分之前,先给出如下三个参数的定义:
hop1上可承载数据的RE个数:
Figure PCTCN2019099037-appb-000059
其中
Figure PCTCN2019099037-appb-000060
为hop1的符号个数,
Figure PCTCN2019099037-appb-000061
为集合
Figure PCTCN2019099037-appb-000062
的大小,集合
Figure PCTCN2019099037-appb-000063
为符号上l上可承载数据的RE个数。
hop2上可承载数据的RE个数:
Figure PCTCN2019099037-appb-000064
其中
Figure PCTCN2019099037-appb-000065
为hop2的符号个数。
PUSCH hop1上第一个连续DMRS符号集合之后的PUSCH符号上可承载数据的RE个数:
Figure PCTCN2019099037-appb-000066
其中l (1)的定义是第一个连续DMRS符号集合之后的第一个不含DMRS的符号索引;连续的DMRS符号集合,可以包含1个DMRS符号,也可以包含多个连续的DMRS符号。
UCI各部分(HARQ-ACK、CSI-part1和CSI-part2)的编码比特数跳频拆分规则如下。
HARQ-ACK编码比特的跳频拆分规则:
假设HARQ-ACK的编码比特数为G ACK,则hop1和hop2上发送的HARQ-ACK编码比特数分别为:
Figure PCTCN2019099037-appb-000067
G ACK(2)=G ACK-G ACK(1)。
CSI-part1编码比特的跳频拆分规则:
假设CSI-part1的编码比特数为G CSI-part1,则hop1和hop2上发送的CSI-part1编码比特数分别为:
Figure PCTCN2019099037-appb-000068
G CSI-part1(2)=G CSI-part1-G CSI-part1(1)          (6)
当式(4)的取最小运算min(·,·)取逗号左边时,结合式(5)和(6)可知,
G CSI-part1(1)≤G CSI-part1(2)         (7)
其中等号只在G CSI-part1可以整除(2·N L·Q m)时成立。
CSI-part2编码比特的跳频拆分规则:
假设CSI-part2的编码比特数为G CSI-part2,则hop1和hop2上发送的CSI-part2编码比特数分别为:
G CSI-part2(1)=M 1·N L·Q m-G CSI-part1(1)        (8)
G CSI-part2(2)=M 2·N L·Q m-G CSI-part1(2)         (9)
当UCI-only场景中存在以下三个条件时,存在CSI-part1的发送不完整的问题。
条件1:CSI-part1的编码比特数刚好等于PUSCH的hop1和hop2上除了预留RE之外所有可承载数据的RE所映射的编码比特数,即
Figure PCTCN2019099037-appb-000069
条件2:G CSI-part1不能整除(2·N L·Q m)。因此,式(7)不能取等号,即
G CSI-part1(1)<G CSI-part1(2)         (11)
条件3:两个跳频资源的可用于承载数据的RE个数相等,即对于PUSCH hop1和hop2,有M 1=M 2        (12)
由式(8)(9)(11)(12)可知,
G CSI-part2(1)>G CSI-part2(2)       (13)
由式(8)(9)相加可得,
G CSI-part2(1)+G CSI-part2(2)=(M 1+M 2)·N L·Q m-G CSI-part1      (14)
由式(14)和(10)可得,
Figure PCTCN2019099037-appb-000070
由式(13)和(15)可得,
Figure PCTCN2019099037-appb-000071
由式(16)和(4)可得,
Figure PCTCN2019099037-appb-000072
因此,由式(9)和(17)可知,
Figure PCTCN2019099037-appb-000073
即hop2上的CSI-part1编码比特数,大于非预留RE所映射的编码比特数;而CSI-part1是不能用预留RE承载的。因此,CSI-part1的发送不完整。
除此之外,由于
Figure PCTCN2019099037-appb-000074
因此可能会有预留RE无任何数据可发送,如图3所示。如果PUSCH是单载波的离散傅里叶变换扩频的正交频分复用(discrete Fourier transform spread orthogonal frequency division multiplexing,DFT-s-OFDM),则上述不发送任何数据的RE可能破坏hop2一个或多个符号的上行发送单载波低峰均功率比(peak-to-average power ratio,PAPR)的特性。
另外,本申请中所涉及的符号为一个时间单位,可以为正交频分复用(orthogonal frequency-division multiplexing,OFDM)符号。
有鉴于此,本申请提供了一种通信方法,能够解决上述CSI-part1的发送不完整,此外,还能够解决上述采用DFT-s-OFDM波形在hop2上发送信号时单载波特性被破坏的问题。
如图4所示,该通信方法包括:
S410,接收下行控制信息,该下行控制信息用于调度PUSCH,PUSCH仅用于承载UCI,该PUSCH包含第一跳频资源和第二跳频资源,所述第一跳频资源的时域起始符号位于所述第二跳频资源的时域起始符号之前。
PUSCH仅用于承载UCI指的是通信协议中定义的UCI-only场景。第一跳频资源和第二跳频资源例如是上述hop1和hop2。可选的,第一跳频资源与第二跳频资源的频域资源相异,上述相异指的是第一跳频资源的频域资源与第二跳频资源的频域资源部分重叠或者完全不重叠。进一步可选的,所述第一跳频资源的时频结束位置与所述第二跳频资源的时域起始位置相邻。或者,所述第一跳频资源为时域上连续或者不连续的资源,所述第二跳频资源为时域上连续或不连续的资源。该跳频资源的解释可以应用于本申请中其它方法或者实施方式。
S410所述的下行控制信息例如是通过PDCCH传输的下行控制信息(downlink control information,DCI),基站可以通过DCI中的1个比特的不同状态指示PUSCH是否仅用于传输UCI,即,该1个比特的不同状态用于指示当前通信场景是否为UCI-only。
S420,在PUSCH上发送第一UCI,第一UCI包含HARQ-ACK、CSI-part1和CSI-part2中的至少一个;
其中,第一跳频资源中的预留RE上映射的编码比特数为第一数值,第二跳频资源中的预留RE上映射的编码比特数为第二数值,第一数值不小于第二数值,第一跳频资源中 的预留RE和第二跳频资源中的预留RE是为比特数不大于2的潜在HARQ-ACK传输预留的RE。这里对“潜在HARQ-ACK传输”进行进一步解释说明,本申请实施例中,HARQ-ACK可能会在PUSCH上进行传输,也可能不进行实际传输,不论传输与否,这些预留RE都会预留,这些预留RE对应一定数量的、映射在其上的编码比特数。具体的,所述“潜在HARQ-ACK传输”中所涉及的HARQ-ACK比特数不大于2,并且,具体计算映射的编码比特数时,会按照HARQ-ACK比特数等于2来计算预留RE映射的编码比特数。本申请实施例中涉及预留RE上映射的编码比特数时,若不存在实际传输,则可以理解为所述预留RE上能够映射的编码比特数,或者说对应的相应数量的编码比特数。
CSI-part1出现信息发送不完整的原因在于,CSI-part1映射在第二跳频资源上的编码比特数较少,也就是说,第二跳频资源上用于映射CSI-part1的RE数量较少,导致CSI-part1无法全部映射到第二跳频资源上,本申请提供的通信方案,相对于现有技术减少第二跳频资源中预留RE能够映射的编码比特数,从而增加了第二跳频资源中用于映射CSI-part1的RE的数量,解决了UCI-only场景中通过跳频传输UCI导致CSI-part1出现信息发送不完整的问题。
此外,由于上述方案减少了第二跳频资源中预留RE的数量,避免了第二跳资源上存在无数据发送的预留RE的情况,因此,方法400解决了上述CSI-part1发送不完整的问题的同时解决了图3所示的问题。
需要说明的是,上述“第一跳频资源中的预留RE映射的编码比特数为第一数值,第二跳频资源中的预留RE映射的编码比特数为第二数值,第一数值不小于第二数值”指的是:通过减少第二跳频资源中预留RE的数量使得第二数值大于或等于第一数值。
可选地,方法400还包括:
确定第一编码比特数

确定。
具体的,上述“第一跳频资源中的预留RE和第二跳频资源中的预留RE上映射的编码比特数”指的是第一跳频资源中的预留RE和第二跳频资源中的预留RE能够映射的编码比特数之和,而不应被理解为第一跳频资源中的预留RE和第二跳频资源中的预留RE实际映射的编码比特数。

本申请中需要说明的是,其中第一组连续的DMRS符号的解释是,从相应资源时域上的第一个DMRS符号开始,直到连续的DMRS符号结束。具体参见图5,图5中从上到下(上下顺序仅用于逻辑区分4个PUSCH资源,不限定任何频域位置关系)展示了4个PUSCH资源-PUSCH1、PUSCH2、PUSCH3以及PUSCH4,所述PUSCH1和PUSCH3的起始符号为DMRS符号,所述PUSCH2和PUSCH4的起始符号不是DMRS符号。另外,所述PUSCH1和PUSCH2中的第一组连续的DMRS符号仅包含1个符号,PUSCH3和PUSCH4中的第一组连续的DMRS符号包含多个符号。
可选地,第一UCI中的HARQ-ACK在第二跳频资源上映射的编码比特数为G ACK(2),G ACK(2)=G ACK-G ACK(1)。
本申请中相关术语的解释可以参照通信协议(3GPP TS38.212 v15.2.0的6.2.7小节)中的定义。
下面,再给出了本申请提供的跳频传输的例子。
步骤一:gNB通过RRC信令为UE配置尺度参数α,码率补偿参数
Figure PCTCN2019099037-appb-000089
Figure PCTCN2019099037-appb-000090
等参数,其中,尺度参数α取值为大于0且小于等于1,上述码率补偿参数的配置方式可以是配一组值,也可以配多组值。如果配一组值,则直接在后续步骤中改组值;如果配置多组值,则可以由步骤二中的下行控制信息(downlink control information,DCI)来指示其索引。
步骤二:gNB通过PDCCH向UE发送DCI,所述DCI中包括但不限于以下信息:为所述UE分配的PUSCH资源,PUSCH是否为UCI-only(或者说,是否包含UL-SCH),PUSCH是否跳频,PUSCH传输层数,以及调制与编码策略索引(I MCS),PUSCH传输层数N L
Figure PCTCN2019099037-appb-000091
Figure PCTCN2019099037-appb-000092
的索引(可选)等参数。
步骤三:UE接收到DCI后,解析出为UE分配的PUSCH资源,PUSCH是否为UCI-only,PUSCH是否跳频,以及I MCS,PUSCH传输层数N L等参数;UE通过I MCS查表得到码率R和调制阶数Q m;如果DCI中有
Figure PCTCN2019099037-appb-000093
Figure PCTCN2019099037-appb-000094
的索引,则UE根据索引解析出
Figure PCTCN2019099037-appb-000095
Figure PCTCN2019099037-appb-000096
的值,并在后续步骤中使用。
步骤四:如果UE解析出PUSCH为UCI-only,且UE需要发送的HARQ-ACK信息比特数不大于2(即HARQ-ACK信息比特数为0、1或2),则UE按照如下式子来计算为HARQ-ACK保留的预留RE个数(下列式子中,分母上的2即为按照HARQ-ACK信息比特为2来计算):
Figure PCTCN2019099037-appb-000097
其中
Figure PCTCN2019099037-appb-000098
为PUSCH的符号l上可以承载UCI的RE个数,l 0为PUSCH第一个DMRS符号或第一组连续多个DMRS符号集后的第一个不含DMRS的符号索引;
Figure PCTCN2019099037-appb-000099
为PUSCH的符号数。
然后根据得到的Q′ ACK来计算可能需要为HARQ-ACK保留的预留RE所映射的编码比特数
Figure PCTCN2019099037-appb-000100
另外,UE根据α,
Figure PCTCN2019099037-appb-000101
R,Q m,N L等参数,计算得到HARQ-ACK编码比特数G ACK,CSI-part1编码比特数G CSI-part1,CSI-part2编码比特数G CSI-part2
步骤五:如果UE解析出PUSCH需要跳频,则UE按如下式子分别计算HARQ-ACK、CSI-part1和CSI-part2在hop1和hop2上的编码比特数:
Figure PCTCN2019099037-appb-000102
或者,
Figure PCTCN2019099037-appb-000103

Figure PCTCN2019099037-appb-000104
G CSI-part1(2)=G CSI-part1-G CSI-part1(1);
G CSI-part2(1)=M 1·N L·Q m-G CSI-part1(1);
G CSI-part2(2)=M 2·N L·Q m-G CSI-part1(2);
UE按照如下式子分别计算hop1和hop2上为HARQ-ACK保留的预留RE所映射的编码比特数:
Figure PCTCN2019099037-appb-000105
Figure PCTCN2019099037-appb-000106
步骤六:UE按照步骤五计算得到的参数,将HARQ-ACK,CSI-part1和CSI-part2编码比特映射到PUSCH上。
下面,通过几个例子来说明采用本申请提供的通信方法(例如,采用
Figure PCTCN2019099037-appb-000107
进行跳频传输)计算在两个hop上的映射编码比特数所带来的有益效果。表1为使用现有技术的方法得到的结果,表2为使用本申请的方法得到的结果。
表1
Figure PCTCN2019099037-appb-000108
从表1的倒数第二行和倒数第三行可知,hop2上被非预留RE传输的编码比特数与CSI-part1映射在非预留RE上的编码比特数不同,可见CSI-part1在hop2上不能被非预留RE完全承载,会导致CSI-part1发送不完整;从表1的倒数第一行和倒数第四行可知,hop2的预留RE映射的编码比特数
Figure PCTCN2019099037-appb-000109
大于CSI-part2在hop2上映射的编码比特数,可见有些预留RE没有数据发送,在PUSCH使用DFT-s-OFDM时,会破坏其单载波低PAPR特性。
上述示例仅是举例说明。
表2为采用本申请提供的通信的方法计算的结果,从表2的倒数第二行和倒数第三行可知,hop2上被非预留RE传输的编码比特数与CSI-part1映射在非预留RE上的编码比特数相同。从表2的倒数第一行和倒数第四行可知,hop2的预留RE映射的编码比特数
Figure PCTCN2019099037-appb-000110
等于CSI-part2在hop2上映射的编码比特数,所有的预留RE均有数据发送。可见本发明的计算方法,分别对齐了两个hop中非预留RE所映射的编码比特数与CSI-part1在两个hop的编码比特数,解决了已有技术的问题。
表2
Figure PCTCN2019099037-appb-000111
Figure PCTCN2019099037-appb-000112
现有技术提供的HARQ-ACK编码比特的跳频拆分规则为:
假设HARQ-ACK的编码比特数为G ACK,则hop1和hop2上发送的HARQ-ACK编码比特数分别为:
Figure PCTCN2019099037-appb-000113
G ACK(2)=G ACK-G ACK(1)。
上述拆分规则存在的问题是hop1的非预留RE不足以承载CSI-part1在hop1的编码比特数,导致CSI-part1发送不完整。
原因如下:
公式(X)中,取最小函数min(·,·)右边的参数M 1·N L·Q m-G ACK(1)的作用是限制CSI-part1在hop1所占的资源上限(后面称其为第一上限),即不能占HARQ-ACK在hop1的资源。但是,基于通信协议的规定,CSI-part1也不能占hop1的预留RE资源,即也应该满足不大于
Figure PCTCN2019099037-appb-000114
这个上限(后面称其为第二上限)。
在HARQ-ACK信息比特数为0,1或2时,G ACK是按实际的HARQ-ACK信息比特数计算出的编码比特数,而
Figure PCTCN2019099037-appb-000115
是按HARQ-ACK信息比特数为2计算出的预留RE所映射的编码比特数,因此如果实际的HARQ-ACK信息比特数为0或1,则有
Figure PCTCN2019099037-appb-000116
从而对hop1有
Figure PCTCN2019099037-appb-000117
这时候第一上限大于第二上限,可能导致hop1的非预留RE不足以承载CSI-part1在hop1的编码比特数G CSI-part1(1)。
有鉴于此,本申请提供了另一种通信方法600,该方法600可以在上述方法的基础上实现,或者与上述方法结合实现,也可以独立实现。如图6所示,包括:
S610,接收下行控制信息,所述下行控制信息用于调度PUSCH,所述PUSCH仅用于承载UCI,所述PUSCH包含第一跳频资源和第二跳频资源,所述第一跳频资源的时域起始符号位于所述第二跳频资源的时域起始符号之前。

现有技术中第五数值仅基于G ACK(1)确定,例如,现有技术的第五数值为M 1·N L·Q m-G ACK(1),该参数限制了CSI-part1在第一跳频资源上所占的资源上限(即,第一上限),此外,CSI-part1也不能占用第一跳频资源的预留RE,即,G CSI-part1(1)也应满足不大于
Figure PCTCN2019099037-appb-000120
这个上限(即,第二上限),在HARQ-ACK的信息比特数为0或1或2时,G ACK(1)为按照实际的HARQ-ACK信息比特数计算出的编码比特数,而
Figure PCTCN2019099037-appb-000121
是按HARQ-ACK信息比特数为2计算出的预留RE所映射的编码比特数,因此,如果实际的HARQ-ACK信息比特数为0或1,则有
Figure PCTCN2019099037-appb-000122
从而有
Figure PCTCN2019099037-appb-000123
即,第一跳频资源上
Figure PCTCN2019099037-appb-000124
这时候第一上限大于第二上限,现有技术仅根据G ACK(1)确定第五数值可能导致第一跳频资源上的非预留RE不足以承载CSI-part1在第一跳频资源上的编码比特数G CSI-part1(1)。
本申请提供的方案中,第五数值基于G ACK(1)和
Figure PCTCN2019099037-appb-000125
中较大的确定(其中
Figure PCTCN2019099037-appb-000126
在HARQ-ACK比特数大于2时等于0),保证在计算G CSI-part1(1)时以第一跳频资源中实际的非预留RE为基准,从而能够避免上述CSI-part1发送不完整的问题。
可选地,

其中,所述N L为所述PUSCH的传输层数,所述Q m为所述第一UCI的调制阶数。
方法600可以单独实施,也可以与方法400联合实施。
本申请还提供了一种通信方法,如图7所示,该方法700包括:
S710,发送下行控制信息,所述下行控制信息用于调度PUSCH,PUSCH仅用于承载UCI,PUSCH包含第一跳频资源和第二跳频资源,所述第一跳频资源的时域起始符号位于所述第二跳频资源的时域起始符号之前。
S720,在PUSCH上接收第一UCI,第一UCI包含HARQ-ACK、CSI-part1和CSI-part2 中的至少一个;其中,第一跳频资源中的预留RE上映射的编码比特数为第一数值,第二跳频资源中的预留RE上映射的编码比特数为第二数值,第一数值不小于第二数值,第一跳频资源中的预留RE和第二跳频资源中的预留RE是为比特数不大于2的潜在HARQ-ACK传输预留的RE。
CSI-part1出现信息发送不完整的原因在于,CSI-part1映射在第二跳频资源上的编码比特数较少,也就是说,第二跳频资源上用于映射CSI-part1的RE数量较少,导致CSI-part1无法全部映射到第二跳频资源上,本申请提供的通信方案,相对于现有技术减少了第二跳频资源中预留RE能够映射的编码比特数,从而增加了第二跳频资源中用于映射CSI-part1的RE的数量,解决了UCI-only场景中通过跳频传输UCI导致CSI-part1出现信息发送不完整的问题。
