具体实施方式
下面结合附图和实施例对本申请进行说明。可以理解的是，此处所描述的实施例仅仅用于解释本申请，而非对本申请的限定。为了便于描述，附图中仅示出了与本申请相关的部分而非全部结构。
在涉及空间、时域、频域、波束等多种复杂因素的支持重复传输的场景下，缺乏有效的机制来统一高效地规划物理上行信道传输，由于无法准确地确定进行物理上行信道传输的信道状态信息，物理上行信道传输的可靠性低。
本申请实施例中提供了一种信息确定方法，根据指示信息准确地确定各次重复传输的信道状态信息，据此进行传输，以提高物理上行信道传输的可靠性。
图1为一实施例提供的一种信息确定方法的流程图。本实施例的信息确定方法可应用于第一通信节点，第一通信节点可以为用户终端(User Equipment，UE)。如图1所示，本实施例的方法包括步骤110和步骤120。
在步骤110中，接收指示信息。
在步骤120中，根据所述指示信息确定M次物理上行信道传输的信道状态信息，其中，M为大于或等于1的整数。
本实施例中，UE接收第二通信节点(第二通信节点为服务节点，例如基站)的指示信息，根据指示信息进行M次物理上行信道传输，例如物理上行共享信道(Physical Uplink Shared Channel，PUSCH)的传输。M次物理上行信道传输，可以是M个用于传输物理上行数据的物理上行信道资源的传输，或是一个物理上行信道资源在不同传输时间、或者不同传输载波、不同传输子带上的一次传输、或是不同层的传输。M次物理上行信道传输对应于一定数量的上行传输块，可以根据空间、时域、频域等按照上行传输块完成上行传输，从而统一高效地进行物理上行信道传输，提高上行传输的可靠性。M次物理上行信道传输可以对应于UE的不同天线面板，上述天线面板可以是一个传输接收点或者通信节点。不同的天线面板可以用空间参数，例如发送波束，接收波束，空间传输滤波器，准共位置类型类型D(type D)等代替。本申请中的空间传输滤波器决定了该天线面板上的发送波束和接受波束的方向。例如，对应于相同空间传输滤波器的PUSCH传输可由同一个天线面板进行传输，即，对应于相同空间传输滤波器的PUSCH传输具有相同的发送波束方向。
在一实施例中，所述指示信息包括以下至少之一：传输方案指示；时频域资源指示；传输块个数指示，所述时频域资源指示和所述传输块个数指示分别与传输方案指示相对应；所述信道状态信息包括以下至少之一：时频域资源；传输块个数；空间传输滤波器；冗余版本(Redundancy Version，RV)RV；传输上行预编码矩阵指示信息(Transmitted Precoding Matrix Indicator，TPMI)；解调参考信号(Demodulation Reference Signal，DMRS)端口；调制与编码策略(Modulation and Coding Scheme，MCS)；功率控制参数。
本实施例中，传输方案指示用于指示物理上行信道传输的传输方案，从而相应地指示出传输块的个数、M次物理上行信道传输与传输块的对应关系、各次物理上行信道传输占用的时频域资源等，UE据此可以准确确定信道状态信息并进行物理上行信道传输。
在一实施例中，所述指示信息通过以下信息域中的至少之一指示：无线资源控制(Radio Resource Control，RRC)信令；介质访问控制层控制单元(Media Access Control-Control Element，MAC-CE)；下行控制信息(Downlink Control Information，DCI)。
在一实施例中，在传输方案指示为第一传输方案的情况下，对应的传输块个数指示为1，对应的时频域资源指示为：M次物理上行信道传输对应于相同的时域资源；每次物理上行信道传输分别对应于一段频域资源，各段频域资源之间不重叠。
本实施例中，M次物理上行信道传输对应于一个上行传输块，M次物理上行信道传输占用相同的时域资源和不同的频域资源，M次物理上行信道传输对应于M段互不重叠的频域资源。
在一实施例中，在传输方案指示为第二传输方案的情况下，对应的传输块个数指示为M，对应的时频域资源指示为：所述M次物理上行信道传输对应于M个相同的上行传输块；M次物理上行信道传输对应于相同的时域资源以及相同的频域资源；每个上行传输块对应于一层或多层传输。
本实施例中，M次物理上行信道传输对应于M个相同的上行传输块。上行传输块也可以称为传输信息，例如信道编码前的信息，或者上行信息中一个编码块，或者多个子编码块所对应的一个大的编码块等。M个相同的上行传输块是指，M个上行传输块携带了完全相同的待传输信息，即M个上行传输块是重复传输的。M次物理上行信道传输占用相同的时域资源和相同的频域资源，每个上行传输块对应于一层或多层传输。
在一实施例中，在传输方案指示为第三传输方案的情况下，对应的传输块个数指示为M，对应的时频域资源指示为：M次物理上行信道传输对应于M个相同的上行传输块；M次物理上行信道传输对应于相同的时域资源；每次物理上行信道传输分别对应于一段频域资源，各段频域资源之间不重叠。
本实施例中，M次物理上行信道传输对应于M个相同的上行传输块，M次物理上行信道传输占用相同的时域资源和不同的频域资源，M次物理上行信道传输对应于M段互不重叠的频域资源。
在一实施例中，在一实施例中，在传输方案指示为第四传输方案的情况下，对应的传输块个数指示为M，对应的时频域资源指示为：M次物理上行信道传输对应于M个相同的上行传输块；每次物理上行信道传输分别对应于一段时域资源，各段时域资源之间不重叠；所述M次物理上行信道传输对应于N段频域资源，各段频域资源之间不重叠，其中，N为大于或等于1的整数且N为小于 或等于M的整数。
本实施例中，M次物理上行信道传输对应于M个相同的上行传输块，即M个上行传输块是重复传输的。M次物理上行信道传输占用不同的时域资源以及N段互不重叠的频域资源，其中，1≤N≤M。在N＝1的情况下，M次物理上行信道传输对应于相同的频域资源；在N＝M的情况下，M次物理上行信道传输对应于互不重叠的频域资源；在1＜N＜M的情况下，M次物理上行信道传输对应的频域资源存在相同的情况，也存在不重叠的情况。
在一些实施例中，N为空间传输滤波器的个数，即，M次物理上行信道传输对应于N个空间传输滤波器。
在一实施例中，在传输方案指示为第五传输方案的情况下，对应的传输块个数指示为M，对应的时频域资源指示为：M次物理上行信道传输对应于M个相同的上行传输块；M次物理上行信道传输对应于相同的频域资源；每次物理上行信道传输分别对应于一段时域资源，各段时域资源之间不重叠。
本实施例中，M次物理上行信道传输对应于M个相同的上行传输块，M次物理上行信道传输占用相同的频域资源和不同的时域资源，M次物理上行信道传输对应于M段互不重叠的时域资源。
在一实施例中，M次物理上行信道传输的频域资源包括第一频域资源和第二频域资源；M次物理上行信道传输的频域资源对应于第一频率偏移量和第二频率偏移量；其中，第一频率偏移量为所述第二频域资源的起始频率与第一频域资源的起始频率的差值，第二频率偏移量为所述第一频域资源的起始频率与带宽部分(Bandwidth Part，BWP)的起始频率的差值。
本实施例中，将M次物理上行信道传输的频域资源划分为两部分：第一频域资源和第二频域资源。两部分频域资源(的起始频率)之间具有第一频率偏移量X offset，第一频域资源的起始频率与BWP的起始频率之间具有第二频率偏移量X start。
在一实施例中，在第二频率偏移量不为0且存在至少一次物理上行信道传输的频率范围超出BWP的边界的情况下，超出边界的频率部分通过BWP的目标频段传输，其中，目标频段包括BWP的起始频率与所述第一频域资源的起始频率之间的频段。
本实施例中，BWP的起始频率之后的X start为第一频域资源的起始频率，第一频域资源的起始频率之后的X offset为第二频域资源的起始频率，如果X start不为0，且由于X start和X offset的存在，导致靠后的物理上行信道传输的频率范围超出BWP的边界，则通过X start的频段传输超出边界的部分(超出边界的部分可 能为一次物理上行信道传输，也可能存在多次物理上行信道传输都超出边界)，从而提高资源的利用率，提高上行传输的可靠性。
在一实施例中，M次物理上行信道传输对应于相同的MCS。
在一实施例中，M次物理上行信道传输对应于相同的DMRS端口；或者，M次物理上行信道传输对应于M个不同的DMRS端口，其中，M大于或等于2。

本实施例中，M次物理上行信道传输与TPMI之间的对应关系有三种，其中，各次物理上行信道传输依次对应于一个TPMI，各所述TPMI按照码本表的顺序循环排列是指：UE可以按照码本表中给定的TPMI及TPMI的排列顺序，轮询选取TPMI依次对应于M次物理上行信道传输。例如，38.212中的表7.3.1.1.2-3，如果UE天线属性为部分天线相关传输，基站给UE指示了起始索引值4，对应TPMI＝4，则UE按照表格中间“天线非相关和部分相关”一列的顺序依次选取TPMI索引值，将TPMI＝4应用于第一次PUSCH传输，将TPMI＝5应用于第二次PUSCH传输，以此类推。
在一实施例中，M次物理上行信道传输对应于相同的RV；或者，对应于相同的空间传输滤波器的物理上行信道传输对应于相同的RV；或者，各次物理上行信道传输依次对应于一个RV，各所述RV按照设定顺序循环排列。
