Description

一种传输方法、装置和系统 技术领域
本公开实施例涉及通信领域，尤指一种传输方法、装置和系统。
背景技术
在新一代移动通信系统(NR，New Radio)中，对于一个用户设备(UE，User Equipment)，上行控制信息(UCI，Uplink Control Information)能够通过物理上行共享信道(PUSCH，Physical Uplink Shared Channel)进行传输，且允许UE没有实际的上行数据，即PUSCH中只有UCI，没有上行共享信道(UL-SCH，Uplink Shared Channel)。这种情况下，基站为UE分配的PUSCH资源实际被用于传输UCI。
目前在NR中，允许使用PUSCH的所有调制方式和码率来传输UCI。例如，允许使用较高阶的调制方式(如正交幅度调制(QAM，Quadrature Amplitude Modulation)256)传输UCI，以提升数据的传输效率。但是，为了保证UCI的可靠性传输，一般使用低阶调制方式(如正交相移键控(QPSK，Quadrature Phase Shift Key)来传输UCI。这样，如果基站配置UE在PUSCH中传输UCI时，配置了较高阶的调制方式和较多的时频资源来满足UCI传输的低码率要求，尤其是信道质量较差的情况，那么，当传输的UCI比特数较少时，为UE分配很多的时频资源和高阶的调制方式无疑降低了传输效率，并且增加了UE的复杂度，浪费了时频资源。
进一步的，由于目前NR系统中，支持PUSCH时分复用传输在一个时隙中，所以当UCI在PUSCH中传输时，面临一个新问题，即UCI被确定在一个时隙中传输时，但是该时隙中有多个PUSCH时，那么UE在哪个PUSCH中传输呢？

本公开实施例包括：当UCI被配置在PUSCH中传输，且PUSCH中没有UL-SCH时，依据UCI的实际码率以及预设门限确定传输UCI；其中，所述预设门限根据预定码率和预定贝塔β值确定，这是一种易于实现的处理。本公开实施例中，当基于一种给定的调制方式来传输UCI时，依据UCI的实际码率以及预设门限确定传输UCI，这种限制将使得在给定的调制方式、传输UCI比特数确定的情况下，分配的时频资源是相对合理，即能够实现与调制方式匹配的码率，从而提升了传输效率，降低了实现复杂度。

其中，r为所述预定码率，β为所述预定贝塔值，c为调整因子，Qm为所述调制方式对应的调制阶数。本公开实施例采用这种方式可以确保，对于给定的调制方式，总是使用调制方式对应的最佳码率来传输数据，从而将一些低效的码率排除掉。例如，众所周知的，高阶调制方式一般被使用在信道质量很好的情况下，此时对应的实际传输码率很高，使用时频资源少，且能够被接收端正确解码，这样以实现数据的高 效传输。但是，当信道质量不好，仍然使用高阶调制方式时，那么为了保证传输的可靠性，需要使用更多的时频资源，通过不断的重复编码以实现更低的实际码率，这样，才能使得高阶调制方式传输的数据在接收端正确解码。显然，后者是一种低效的方式，应该被禁止。所以，每种调制方式，都存在自己最佳的码率。也就是说，对于一种调制方式，如果过分低于对应的最佳码率，将导致传输效率低下，所以通过限制实际码率的下限，可以避免上述的过分低于调制方式对应的最佳码率发生，从而提高传输效率。
本公开实施例的其它特征和优点将在随后的说明书中阐述，并且，部分地从说明书中变得显而易见，或者通过实施本公开实施例而了解。本公开实施例的目的和其他优点可通过在说明书、权利要求书以及附图中所特别指出的结构来实现和获得。

上述推导中使用了CSI-1的进行的，但是这个推导的结论被使用为其他类型的上行控制信息。
在本公开实施例中，依据所述上行控制信息的实际码率以及预设门限传确定传输上行控制信息包括：
当所述实际码率大于或等于所述预设门限时，在所述物理上行共享信道中传输所述上行控制信息。
在本公开另一个实施例中，该方法还包括：当所述实际码率小于所述预设门限时，不在所述物理上行共享信道中传输所述上行控制信息。
其中，不在PUSCH中传输UCI可以是指在不同于PUSCH的信道中传输UCI；或者，不传输UCI。
在本公开实施例中，预设门限根据预定码率和预定贝塔值确定包括：
所述预设门限为：
Figure PCTCN2019084624-appb-000015
或者
Figure PCTCN2019084624-appb-000016
其中，r为所述预定码率，β为所述预定贝塔值，c为调整因子，Qm为所述调制方式对应的调制阶数(如表3所示)；
或者，预设门限为：
Figure PCTCN2019084624-appb-000017
或者

其中，r为所述预定码率，且所述预定码率为在调制编码表中配置的调制方式对应的码率的最小值，β为所述预定贝塔值，c为调整因子。
其中，c为大于0的整数。
本公开实施例采用这种方式可以确保，对于给定的调制方式，总是使用调制方式对应的最佳码率来传输数据，从而将一些低效的码率排除掉。例如，众所周知的，高阶调制方式一般被使用在信道质量很好的情况下，此时对应的实际传输码率很高，使用时频资源少，且能够被接收端正确解码，这样以实现数据的高效传输。但是，当信道质量不好，仍然使用高阶调制方式时，那么为了保证传输的可靠性，需要使用更多的时频资源，通过不断的重复编码以实现更低的实际码率，这样，才能使得高阶调制方式传输的数据在接收端正确解码。显然，后者是一种低效的方式，应该被禁止。所以，每种调制方式，都存在自己最佳的码率。也就是说，对于一种调制方式，如果过分低于对应的最佳码率，将导致传输效率低下，所以通过限制实际码率的下限，可以避免上述的过分低于调制方式对应的最佳码率发生，从而提高传输效率。
在本公开实施例中，预定码率和预定贝塔值可以采用以下(1)～(8)中的任一种取值。
(1)预定码率为物理上行控制信道(PUCCH，Physical Uplink Control Channel)对应的码率(如表1-1所示)的最小值，所述预定贝塔值为UCI对应的贝塔β值的最大值(如表2所示的最大值)。
其中，UCI在PUSCH中传输时，UCI允许使用的码率包括如表1-1到表1-4所示中的任意一个，表1-1来自3GPP TS 38.213 V15.1.0(2018-03)的表格9.2.5.2-1，表1-2来自3GPP TS 38.214中的表格6.1.4.1-1，表1-3来自3GPP TS 38.214中的表格5.1.3.1-1，表1-4来自3GPP TS 38.214中的表格5.1.3.1-2。
其中，在3GPP TS 38.214中6.1.4.1节给出了PUSCH使用的码率表(当UCI在PUSCH中传输时，UCI使用PUSCH的码率表格)，注意，其中表5.1.3.1-1和5.1.3.1-2是在6.1.4.1节引述的，在不同情况下，使用不同的码率表格。
在本公开实施例中，来自3GPP TS 38.213 V15.1.0(2018-03)的表格9.2.5.2-1也被认为是UCI允许使用的码率。
下面以表1-1为例，对于其他表格，在本公开实施例中使用原理相同，不分别赘述)。表1-1中定义了不同物理上行控制信道(PUCCH，Physical Uplink Control Channel)格式对应的码率(这个码率是一个参考的码率)，也就是说PUCCH传输是基本要大于或等于下述的码率才能被认为是满足可靠性要求的。当然，不同的码率对应着不同的信道质量或PUCCH中承载的比特数等。但是，一般的，PUCCH对应的业务的可靠性要求比较高时，或者信道质量较差时，会使用较低的码率，相反的，会使用较高的码率。

其中，r min为表1中最小值。β max为表2中的最大值。
这样，当UCI在PUSCH中传输，且PUSCH中没有UL-SCH时，如果BPSK调制方式被配置，那么基站应该配置UE传输UCI的实际码率不小于T m，即当调制方式为BPSK时，UE不期望UCI传输的实际码率小于T m，或UE发现UCI传输的实际码率小于T m时，UE认为这是一个错误，不作处理，即不传输UCI。也就是说，当调制方式为BPSK时，UE只在UCI传输的实际码率不小于T m时传输UCI。

例如，基站配置了r为0.35(参考表1)，配置了beta为1.625(参考表2)，那么在计算T m时r min使用0.35的上一个等级的r＝0.25(即比0.35对应的索引值小的最大索引值对应的码率)代替；β max使用1.625的下一个等级β＝1.750代替。

(8)当UCI使用PUSCH的码率表格时，例如使用表1-2、表1-3和表1-4中任意一个时，还包括下面的确定预设门限T m的方式。
对于给定的调制方式(即Q m的值被给定，它是基站配置的PUSCH的调制方式，用来传输UCI的)，对应的
Figure PCTCN2019084624-appb-000037
其中，r为在调制编码表中配置的调制方式对应的码率的最小值，例如，在表1-2、表1-3或表1-4中配置的调制方式对应的码率的最小值；
β可以采用以下任一种取值：
(1)配置的贝塔值；
(2)UCI对应的贝塔β值的最大值(如表2所示的最大值)；
(3)配置的贝塔值的下一个等级的贝塔值，即比配置的贝塔值对应的索引值大的最小索引值对应的贝塔值时为配置的贝塔值的下一个等级的贝塔值。
具体的，可以直接取配置的贝塔值；或者直接取UCI对应的贝塔β值的最大值；或者，当配置的贝塔值存在下一个等级的贝塔值时，取配置的贝塔值的下一个等级的贝塔值，当配 置的贝塔值不存在向下的等级时，区配置的贝塔值。
例如，当表1-4被使用为UCI在PUSCH中传输(或者表1-4被使用为PUSCH的传输时)，如果配置调制方式为16QAM，即Q m＝4，此时
Figure PCTCN2019084624-appb-000038
中的r为378/1024(即表1-4中16QAM对应的码率有{378/1024,434/1024,490/1024,553/1024,616/1024,658/1024}，其中378/1024最小，被选中，即为码率r)。那么，当UCI(HARQ-ACK、SR、CSI-1和CSI-2中的一个或多个)在PUSCH中传输时，如果PUSCH中没有UL-SCH(即没有UE的上行数据)时，且假设被配置调制方式为16QAM时，当经计算后，UCI传输的实际码率小于378/1024/β(这里假设β采用配置的)时，UE认为是一个错误的配置(不进行UCI的传输)，也就是说，最佳的，基站禁止在调制方式为16QAM时配置这种导致UCI实际码率小于378/1024/β的相关参数。当经计算后，UCI传输实际码率大于或等于378/1024/β时，UE按照配置的相关信息进行UCI的传输。
这种方式能被归纳为：如果UCI被配置在PUSCH中传输，且没有UL-SCH时，为传输UCI配置调制方式、码率等参数时，应使得UCI传输的实际码率大于或等于T m；如果UCI传输的实际码率小于T m，则将导致低效的传输，UE不期望这种配置，认为这是一个错误的配置，不进行UCI传输。这里T m被定义为
Figure PCTCN2019084624-appb-000039
其中，r为在调制编码表中配置的调制方式对应的码率的最小值，例如，在表1-2、表1-3或表1-4中配置的调制方式对应的码率的最小值；
β可以采用以下任一种取值：
(1)配置的贝塔值；
(2)UCI对应的贝塔β值的最大值(如表2所示的最大值)；
(3)配置的贝塔值的下一个等级的贝塔值，即比配置的贝塔值对应的索引值大的最小索引值对应的贝塔值时为配置的贝塔值的下一个等级的贝塔值。
PUSCH在传输时，可以为不同传输模式配置对应的调制编码表。
上述的方式，可以应用于不同类型的上行控制信息，例如上行控制信息为HARQ-ACK、SR、CSI-1和CSI-2中的一个或多个的组合。如果方式中的r或贝塔值需要使用对应的表格时，即每种上行控制信息使用自己对应的表格。例如，上行控制信息为HARQ-ACK时对应使用HARQ-ACK的贝塔值配置表；上行控制信息为CSI-1时对应使用CSI-1的贝塔值配置表；上行控制信息为CSI-2时对应使用CSI-2的贝塔值配置表。
也就是说，上述预定贝塔值来自UCI对应的贝塔值配置表；
或者，上述预定贝塔值为预先设置的常数，例如，为20、25、30、35、40。
在本公开实施例中，UCI的调制方式包括以下至少之一：

实施例
UCI被配置在PUSCH中传输，且PUSCH中没有UL-SCH，基站和UE约定对于基站配置的UCI(包括HARQ-ACK、SR、CSI-1和CSI-2中的一个或多个)的每种调制方式，如果UCI比特的实际码率小于门限Tm，那么UE对于基站的这种配置将不做处理(认为这是一种错误的配置)。也即是说，基站不允许为UE配置UCI传输码率小于Tm。这里的调制方式包括表3中调制方式。然后，对于Tm的确定按照下面的方式之一进行。
基站和UE约定，Tm的取值能通过参数r和beta因子来推导得出。或者当r和beta作为固定值时，为每种调制方式得出一个对应的常值。下面给出多种推导Tm的方式(使用其中一个即可)且以CSI-1为例，对于其他UCI采用类似的(下面方式中，UCI为特别说明应该是指CSI-1因为是以CSI-1为例的)。
方式1
对于采用BPSK调制时，Tm＝r min/beta max，其中，r min为表1中最小值。beta max为表2中为CSI-1的最大值。
这样，基站和UE约定，如果UCI在PUSCH中传输，且没有UL-SCH时，如果BPSK调制被配置，那么基站应该配置UE传输UCI的实际码率不小于Tm。即在BPSK时，UE不期望或UE发现UCI传输的实际码率小于Tm时，UE认为这是一个错误，不作处理。也就是说，对于BPSK时，UE只对于UCI传输的实际码率不小于Tm的情况进行处理。
对于其他的(也可以包括BPSK)调制方式时，对应的Tm为Qm*r min/beta max，Qm的取值见表3。
下面是具体的推导过程。对于UCI传输时的实际码率，按照下面的方式近似计算得到(以CSI-1为例)：(O CSI-1+L CSI-1)/(Q m*Q′ CSI-1)，Q′ CSI-1是CSI-1比特编码后的调制符号数量，O CSI-1是CSI-1比特数，L CSI-1是CSI-1的CRC比特(L CSI-1也能作为可选项)。进一步的，对于Q′ CSI-1的取值进行近似取值，即将
Figure PCTCN2019084624-appb-000045
按照概率大小，选择大括号中前面的等式作为Q′ CSI-1的近似取值，并带入上述的CSI-1的实际码率表达式中。最终，CSI-1的实际码率为r/beta(beta即为
Figure PCTCN2019084624-appb-000046
)。
方式2
对于采用BPSK调制时，Tm＝r min/beta，其中，r min为表1中最小值。beta为基站为UE此次传输UCI配置的，它来自表2中的beta取值。例如，基站为UE配置了在PUSCH(UE没有UL-SCH)中传输UCI的调制方式，以及对应的beta取值。此时UE就使用该配置的beta取值按照要求进行计算。
这样，基站和UE约定，如果UCI在PUSCH中传输，且没有UL-SCH时，如果BPSK 调制被配置，那么基站应该配置UE传输UCI的实际码率不小于Tm。即在BPSK时，UE不期望或UE发现UCI传输的实际码率小于Tm时，UE认为这是一个错误，不作处理。也就是说，对于BPSK时，UE只对于UCI传输的实际码率不小于Tm的情况进行处理。
对于其他的(也可以包括BPSK)调制方式时，对应的Tm为Qm*r min/beta，Qm的取值见表3。
方式3
对于采用BPSK调制时，Tm＝r/beta max，其中，r为基站为UE此次传输UCI配置的，它来自表1中的r取值。例如，基站为UE配置了在PUSCH(UE没有UL-SCH)中传输UCI的调制方式，以及对应的r取值。此时UE就使用该配置的r取值按照要求进行相关的计算。beta max为表2中最大值。
这样，基站和UE约定，如果UCI在PUSCH中传输，且没有UL-SCH时，如果BPSK调制被配置，那么基站应该配置UE传输UCI的实际码率不小于Tm。即在BPSK时，UE不期望或UE发现UCI传输的实际码率小于Tm时，UE认为这是一个错误，不作处理。也就是说，对于BPSK时，UE只对于UCI传输的实际码率不小于Tm的情况进行处理。
对于其他的(也可以包括BPSK)调制方式时，对应的Tm为Qm*r/beta max，Qm的取值见表3。
方式4
对于方式1～3中，如果有r min和/或beta max，在按照下面的方式取值：r min使用基站配置的r的向上的等级(向码率数值减小的方向)的r代替。beta max使用基站配置的beta的向下的等级(向数值增大的方向)的beta代替。如果向上或向下没有对应的等级时，即使用配置的r或beta值。
例如，基站配置了r为0.35(参考表1)，那么在计算r min使用0.35的上一个等级0.25；beta max使用基站配置的beta的向下的等级(向数值增大的方向)的beta代替。例如，基站配置了beta为1.625(参考表2)，那么在计算beta min使用1.625的下一个等级1.750。如果向上或向下没有对应的等级时，即使用配置的r或beta值。
例如，在方式1中，对于配置的调制方式，对应的Tm为Qm*r min/beta max(Qm的取值见表3)，现在按照方式4的处理，那么此时对于配置的调制方式，对应的Tm为Qm*r new/beta new(Qm的取值见表3)，其中r new为配置的r向上的等级的r值；beta new为配置的beta向下的等级的beta值。如果向上或向下没有对应的等级时，即使用配置的r或beta值。
例如，在方式2中，对于配置的调制方式，对应的Tm为Qm*r min/beta(Qm的取值见表3)，现在按照方式4的处理，那么此时对于配置的调制方式，对应的Tm为Qm*r new/beta(Qm的取值见表3)，其中r new为配置的r向上的等级的r值。如果向上或向下没有对应的等级时，即使用配置的r或beta值。
例如，在方式3中，对于配置的调制方式，对应的Tm为Qm*r/beta max(Qm的取值见表3)，现在按照方式4的处理，那么此时对于配置的调制方式，对应的Tm为Qm*r/beta new(Qm的取值见表3)，其中beta new为配置的beta向下的等级的beta值。如果向上或向下没 有对应的等级时，即使用配置的r或beta值。
在方式1～4中，可选的，关于具体的码率计算可以为：按照(O CSI-1+L CSI-1)/(Q m*Q′ CSI-1)，此时计算的码率下，实际传输UCI的PRB数为整数个(即在频域不包含部分PRB，或者频域的PRB数向上取整)。
UCI在PUSCH传输在执行时，如果一个时隙(slot)中有多个PUSCH(PUSCH中可以没有UL-SCH)，那么，基站和UE约定，选择slot中第n个(时间方向)PUSCH信道进行UCI传输(n优选为1)；或者，基站和UE约定，选择slot中PUSCH的时频资源最多的PUSCH进行UCI传输(如果时频资源最多的PUSCH有多个，则选择第一个时频资源最多的PUSCH)。也就是说：用户设备UE被配置将上行控制信息UCI在物理上行共享信道PUSCH中传输，当所述PUSCH所在的时隙slot中有所述UE的多个PUSCH时，选择所述slot中第n个(n优选为1)PUSCH信道进行UCI传输；或者，选择所述slot中所述多个PUSCH中时频资源最多的PUSCH进行UCI传输；或者，基站通过信令通知(例如在DCI中直接通过信令通知或通过其他参数暗含通知)UE在哪个PUSCH中进行UCI传输。对于暗含通知的方式，基站可以通过DCI所在的控制信道单元(CCE，Control Channel Element)索引来推导确定UE在slot中使用的PUSCH为那个。例如，第一个CCE索引值对PUSCH的个数求余，余数表示slot中的第几个PUSCH被使用传输UCI。余数为0表示第一个PUSCH，余数为1表示第二个PUSCH，...，依次类推。
采用选择所述slot中所述多个PUSCH中时频资源最多的PUSCH进行UCI传输的方式，有利于对于PUSCH的性能影响最小化，这样，被打孔的PUSCH数据相对原本整体PUSCH数据较小。采用通知的方式，有利于规避UCI在一些要求可靠性高的业务(例如超可靠低延迟通信(URLLC，Ultra Reliable&Low Latency Communication)业务)的PUSCH中传输，从而不影响URLLC的可靠性。目前UE并不清楚被调度的业务是否为URLLC，但是基站是清楚的。
