为便于更好的理解本申请实施例,对本申请相关的下行多发送接收点(Transmission Reception Point,TRP)的传输方案进行说明。
多个TRP到终端设备间的信道传播特性相对独立,利用多个TRP在空域、时域、频域的重复传输,可以提高数据传输的可靠性,并降低传输的时延。对于理想回程(backhaul)场景,通过单下行控制信息(Downlink Control Information,DCI)调度多个TRP的物理下行共享信道(Physical Downlink Shared Channel,PDSCH)传输,并且多个PDSCH的传输可以采用频分复用(frequency division multiplexing,FDM),空分复用(Spatial Division Multiplexing,SDM),时分复用(Time Division Multiplexing,TDM)等传输方案。
FDM方案:DCI中的传输配置指示(Transmission Configuration Indication,TCI)域的一个码点(codepoint)用于指示两个TCI状态(state),并且DCI中的天线端口(Antenna Port(s))域用于指示同一个码分复用(Code Division Multiplexing,CDM)组(group)中的解调参考信号(Demodulation Reference Signal,DMRS)端口,预编码粒度是频域上连续的资源块,预编码粒度可以是宽带(wideband)、2个资源块(resource block,RB)、4个RB。
在预编码粒度是wideband的情况下,
个物理资源块(Physical resource block,PRB)分配给第一个TCI state,剩下的
个PRB分配给第二个TCI state,n
PRB是分配给UE的PRB总数;
在预编码粒度是2个RB或4个RB的情况下,偶数索引的预编码资源块组(Precoding resource block group,PRG)分配给第一个TCI state,奇数索引的PRG分配给第二个TCI state。其中,除第一个PRG和最后一个PRG,其他PRG包括的RB数与预编码粒度相同,第一个PRG和最后一个PRG包括的RB数大于等于1,且小于等于预编码粒度。
SDM方案:同一个传输块对应的两组数据层分别通过不同的TRP发送,并且在相同的时频资源发送,每个TRP使用不同的一组DMRS端口。
码字映射:多TRP共享一个码字。
DMRS端口:由于每个TRP的大尺度信道特征存在差异,为了保证同一个CDM组内的DMRS端口之间的正交性,要求同一个CDM组的DMRS端口是准共址(Quasi-co-located,QCL)的。因此在设计多TRP协作传输的DMRS端口分配方案时,需要支持至少两个CDM组的DRMS端口分配,即一个CDM组用于一个TRP的数据传输。两个TRP的传输层的组合包括:{1,1},{1,2},{2,2}。

为便于更好的理解本申请实施例,对本申请相关的上行多TRP或天线面板(panel)的传输方案进行说明。
如果终端设备配置有多个panel,且支持在多个panel上同时传输上行信息,则可以同时在多个panel发送多个上行信息,如图2所示,以提高上行的频谱效率。多panel或TRP的上行传输可以是通过单DCI调度的,或者是通过多个DCI调度的,或者是通过RRC信令配置的,或者是RRC信令配置的并且由DCI触发的。在多TRP或多panel的上行传输中,多个上行信息可以采用TDM方案传输,其中,向不同TRP发送的上行信息的传输层数相同。
在一些场景中,在多TRP或panel的上行传输中,考虑引入FDM方案,此情况下,如何对该多个上行信息进行频域资源分配以提升上行传输性能是一项亟需解决的问题。

在本申请一些实施例中,多个上行信息是通过TDM的方式传输的。
在一些实施例中,终端设备可以根据资源分配系数和频域资源分配信息确定多个上行信息对应的频域资源之后,进一步采用TDM的方式传输该多个上行信息。
例如,对于重复类型A(基于slot的PUSCH):在K个连续的时隙的相同符号位置发送多组PUSCH(相同或不同的RV版本),每组PUSCH关联一个空间参数。

应理解,网络设备根据资源分配系数和频域资源分配信息确定至少一个频域资源的方式和终端设备根据资源分配系数和频域资源分配信息确定至少一个频域资源的方式相同,以下,以终端设备根据资源分配系数和频域资源分配信息确定至少一个频域资源为例进行说明,网络设备侧的具体实现参考终端设备侧的实现方式,为了简洁,这里不作赘述。
需要说明的是,本申请实施例可以适用于关联不同空间参数的多个上行信息的频域资源的分配,也可以适用于关联不同空间参数的多个下行信息的频域资源的分配,以下,以确定关联不同空间参数的多个上行信息的频域资源为了进行说明,确定关联不同空间参数的下行信息的频域资源的方式类似,这里不再赘述。例如,网络设备可以根据资源分配信息和频域资源分配信息确定多个频域资源,其中,该多个频域资源关联多个下行信息,其中,该多个下行信息关联不同的空间参数。进一步地,网络设备在该多个频域资源上发送该多个下行信息,对应地,终端设备也可以根据资源分配信息和频域资源分配信息确定多个频域资源,其中,该多个频域资源关联多个下行信息,进一步地,终端设备在该多个频域资源上接收该多个下行信息。
在一些实施例中,多个上行信息是通过FDM方式发送的。在终端设备通过多个panel同时发送上行信息的场景下,不同panel和TRP之间的链路的信道质量的差异可能较差,例如panel1和TRP1之间的链路的信道质量和panel2和TRP2之间的链路的信道质量的差异较大,此情况下,如果采用相同的调制编码方案(Modulation and Coding Scheme,MCS)不利于匹配每条链路的信道质量。因此,在多个上行信息同时传输的场景中,该多个上行信息的MCS可以不同,传输层数也可以不同,以提升上行传输信号以及传输的灵活性。
在本申请一些实施例中,多个上行信息对应的频域资源是根据资源分配系数和频域资源分配信息确定的。
在一些实施例中,多个上行信息对应的频域资源之和为频域资源分配信息所分配的资源。
在一些实施例中,频域资源分配信息是网络设备配置的,该频域资源分配信息可以用于指示网络设备为终端设备分配的可用频域资源。
在一些实施例中,频域资源分配信息是通过DCI指示的。例如,频域资源分配信息可以承载在DCI中的频域资源分配(frequency domain resource allocation)字段中。
在一些实施例中,频域资源分配信息是通过RRC信令指示的。例如,频域资源分配信息可以承载在RRC信令中的频域分配(frequencyDomainAllocation)字段中。
在本申请实施例中,频域资源分配信息或称频域资源配置(frequency domain resource config)信息。
在一些实施例中,资源分配系数用于确定频域资源分配信息所分配的资源的分配方式,例如,资源分配系数用于确定多个上行信息的频域资源在频域资源分配信息所分配的资源所占的比例。
应理解,本申请并不限定资源分配系数的具体表达方式,例如可以采用分数的表达方式,例如资源分配系数可以为1/n,其中,n为大于或等于2的整数,例如,资源分配系数可以为1/2,1/3,1/4,1/5,1/6,1/7,1/8等。
在一些实现方式中,资源分配系数是网络设备配置的。可选地,该资源分配系数可以是网络设备根据预设规则确定的,具体确定方式参考下文描述。
应理解,本申请并不限定资源分配系数的具体配置方式,例如可以是通过DCI,RRC信令,MAC信令或广播消息等信令配置的。
可选地,资源分配系数可以是通过信令中的已有字段指示的,例如利用已有字段中的预留比特指示,或者,也可以在信令中新增字段指示,本申请对此不作限定。
例如,在DCI或RRC信令中新增资源分配系数(Resource allocation factor)字段指示该资源分配系数。
可选地,该资源分配系数字段的大小可以根据总的资源分配系数的数量确定。例如,若候选资源分配系数有8种,则该资源分配系数字段可以为3比特。在一些场景下,在需要携带多个资源分配系数时,信令中可以包括多个资源分配系数字段,或者,也可以是资源分配系数字段占更多个比特数, 例如,资源分配系数资源的不同状态值用于指示对应的一组资源分配系数。
可选地,当通过信令中的预留比特指示资源分配系数时,对于R18版本之前的终端设备,该预留比特仍然解读为预留比特,对于R18版本之后的终端设备该预留比特解读为资源分配系数。
在一些实施例中,资源分配系数的数量可以是一个或者也可以是多个,例如2个,3个,4个等。
可选地,不同数量的资源分配系数可以用于不同数量的多个上行信息的同时传输。
例如,网络设备调度两个上行信息同时传输时,可以配置一个资源分配系数,在配置三个上行信息同时传输时,可以配置两个资源分配系数,或者,在配置四个上行信息同时传输时,可以配置三个资源分配系数。
在另一些实现方式中,资源分配系数是根据预设规则确定的。
也就是说,终端设备和网络设备可以采用一致的方式确定资源分配系数。
综上,网络设备可以给终端设备配置资源分配系数,可选地,该资源分配系数可以是网络设备根据预设规则确定的;或者终端设备和网络设备均根据预设规则确定资源分配系数,即网络设备可以不需要给终端设备配置该资源分配系数。
在一些实施例中,资源分配系数根据多个资源参数(或者说,传输参数)中的至少一个资源参数确定,其中,多个资源参数与多个上行信息关联。
可选地,多个资源参数和多个上行信息关联可以指:多个资源参数和多个上行信息一一关联,其中,资源参数用于传输关联的上行信息。

可选地,时域资源的单位可以是符号,子时隙(sub-slot),时隙,或符号集合等,本申请对此不作限定。
在一些实施例中,多个资源参数包括第一资源参数和第二资源参数,其中,第一资源参数与第一上行信息关联,第二资源参数与第二上行信息关联。
应理解,在本申请实施例中,多个资源参数与多个上行信息关联可以理解为:多个资源参数与多个空间参数关联。例如,第一资源参数和第一空间参数关联,第二资源参数与第二空间参数关联。
在一些实施例中,第一资源参数包括但不限于以下至少之一:

其中,第一MCS等级为第一空间参数关联的MCS等级,或者第一上行信息关联的MCS等级,第一传输层数为第一空间参数关联的第一上行信息的传输层数,第一码率为第一空间参数关联的第一上行信息的目标码率,第一时域资源为第一空间参数关联的第一上行信息的时域资源。
在一些实施例中,第二资源参数包括但不限于以下至少之一:
第二MCS等级,第二传输层数,第二码率,第二时域资源。
其中,第二MCS等级为第二空间参数关联的MCS等级,或者第二上行信息关联的MCS等级,第二传输层数为第二空间参数关联的第二上行信息的传输层数,第二码率为第二空间参数关联的第二上行信息的目标码率,第二时域资源为第二空间参数关联的第二上行信息的时域资源。
在一些实施例中,第一资源参数和第二资源参数可以是网络设备通过一个信令配置的,或者,也可以是通过独立的信令配置的。
例如,网络设备可以通过一个DCI指示第一MCS等级与第二MCS等级,或者,通过单独的DCI指示第一MCS等级与第二MCS等级,或者通过RRC信令配置第一MCS等级与第二MCS等级,或者通过MAC信令配置第一MCS等级与第二MCS等级。
以下,以多个上行信息包括第一上行信息和第二上行信息为例,说明资源分配系数的确定方式,当多个上行信息包括更多个上行信息时确定方式类似,这里不再赘述。
在一些实施例中,资源分配系数根据第一资源参数和/或第二资源参数确定。
在一些实施例中,资源分配系数根据第一资源参数确定,此情况下的资源分配系数可以为第一频域资源在频域资源分配信息所分配的资源中所占的比例。
例如,在第一资源参数大于第一门限时,确定资源分配系数为第一比例,在第一资源参数小于或等于第一门限时,确定资源分配系数为第二比例。
又例如,在第一资源参数大于等于第一门限时,确定资源分配系数为第一比例,在第一资源参数小于第一门限时,确定资源分配系数为第二比例。
可选地,第一比例小于第二比例。
作为一个示例,在第一传输层数大于第一层数阈值时,确定资源分配系数为第一比例,在第一传输层数小于第一层数阈值时,确定资源分配系数为第二比例。
作为又一个示例,在第一MCS等级大于第一MCS阈值时,确定资源分配系数为第一比例,在第一传输层数小于第一MCS阈值时,确定资源分配系数为第二比例。
可选地,第一门限,第一比例,第二比例,第一层数阈值,第一MCS阈值可以是预定义的,或者网络设备配置的。
在又一些实施例中,资源分配系数根据第二资源参数确定,此情况下的资源分配系数可以为第二频域资源在频域资源分配信息所分配的资源中所占的比例。

可选地,第一MCS等级可以是第一MCS索引或第一调制阶数,第二MCS等级可以是第二MCS索引或第二调制阶数。
在一些实施例中,资源分配系数根据第一资源参数和第二资源参数确定。
在一些实施例中,资源分配系数为第一资源参数与第二资源参数的比值。此情况下,资源分配系数可以认为是第一频域资源和第二频域资源的比值。
在一些实施例中,资源分配系数为第一传输层数与第二传输层数的比值。
例如,第一传输层数为1层,第二传输层数为2层,则资源分配系数为1/2,即第一频域资源和第二频域资源的比值为1/2,则第一频域资源占频域资源分配信息所分配的资源的1/3,第二频域资源占频域资源分配信息所分配的资源的2/3。
在另一些实施例中,资源分配系数为第一传输层数与第一传输层数和第二传输层数之和的比值。此情况下,资源分配系数可以认为是第一频域资源占频域资源分配信息所分配的资源的比例。
例如,第一传输层数为1层,第二传输层数为2层,则资源分配系数为1/3,即第一频域资源占频域资源分配信息所分配的资源的1/3,第二频域资源占频域资源分配信息所分配的资源的2/3。
在一些实施例中,资源分配系数为第一MCS等级与所述第二MCS等级的比值。

在另一些实施例中,资源分配系数为第一MCS等级与第一MCS等级和第二MCS等级之和的比值。
例如,第一MCS等级的调制阶数为2,第二MCS等级的调制阶数为2,则资源分配系数为1/2,即第一频域资源占频域资源分配信息所分配的资源的1/2,第二频域资源占频域资源分配信息所分配的资源的1/2。
在一些实施例中,终端设备可以根据第一资源参数确定第一传输块大小(Transport Block Size,TBS),根据第二资源参数确定第二TBS,其中,第一TBS为第一上行信息对应的TBS,第二TBS为第二上行信息对应的TBS。在第一TBS和第二TBS相同的情况下,确定多个上行信息对应的资源分配系数。

情况1:资源分配系数是网络设备配置的。例如,网络设备可以根据预设规则确定资源分配系数。
此情况下,终端设备在获知网络设备配置的资源分配系数之后,可以根据该资源分配系数和频域资源分配信息确定多个上行信息对应的频域资源(步骤X)。网络设备也可以根据自身确定的资源分配系数和频域资源分配信息确定多个上行信息对应的频域资源(步骤Y),其中,步骤Y可以在步骤X之前,或者,也可以在步骤X之后,或者,二者也可以同时执行。在另一些情况下,网络设备首先根据频域资源分配信息确定多个上行信息对应的频域资源,然后根据多个上行信息对应的频域资源生成该资源分配系数,进一步向终端设备发送该资源分配系数,此情况下,网络设备可以不必再根据资源分配系数和频域资源分配信息确定多个上行信息对应的频域资源。
情况2:资源分配系数是根据预设规则的。

应理解,在多个上行信息还包括更多个上行信息时,资源分配系数还用于确定更多个频域资源,例如,在多个上行信息包括第三上行信息时,资源分配系数还用于确定第三频域资源,具体确定方式类似,这里不再赘述。

进一步地,将目标频域资源中除第一频域资源之外的频域资源作为待分配的频域资源(可以理解为剩余的目标频域资源),根据第二资源分配系数将剩余的目标频域资源划分为第二频域资源和第三频域资源。其中,第二频域资源和第三频域资源的分配方式和将目标频域资源划分为第一频域资源和第二频域资源的分配方式类似,这里不再赘述。
在一些实施例中,在多个上行信息包括4个上行信息(例如第一上行信息,第二上行信息、第三上行信息和第四上行信息)时,资源分配系数的数量可以是3个,记为第一资源分配系数r1、第二资源分配系数r2和第三资源分配系数r3,则可以根据第一资源分配系数和目标频域资源确定第一频域资源,根据第一资源分配系数、第二资源分配系数和目标频域资源确定第二频域资源,根据第一资源分配系数、第二资源分配系数和目标频域资源确定第三频域资源,其中,第四上行信息关联的第四频 域资源可以为目标频域资源中除第一频域资源、第二频域资源和第三频域资源之外的频域资源。

可选地,目标频域资源可以是以RB为单位,或者,也可以是以资源块组(resource block group,RBG)为单位,或者,也可以是资源元素(resource element,RE)为单位,或者,也可以是预编码资源块组(Precoding resource block group,PRG)或者也可以是其他资源分配粒度,本申请对此不作限定。
即,上述频域单元可以是RB,RBG,RE,PRG或者,也可以是其他频域单元,本申请对此不作限定。
应理解,上述资源分配系数的配置数量和使用方式仅为示例,但本申请并不限于此。例如当多个上行信息的频域资源平均分配时,可以只配置一个资源分配系数,用于指示每个上行信息所分配的资源的比例,或者,或者,也可以显式配置每个上行信息所分配的资源的比例,例如第一上行信息分配1/3,第二上行信息分配2/3,又例如第一上行信息分配1/2,第二上行信息分配1/3,第三上行信息分配1/6等。
以下,以多个上行信息包括第一上行信息和第二上行信息为例,结合频域资源的跳频类型(即是否使能跳频)和频域资源分配粒度(例如RB和RBG),说明第一频域资源和第二频域资源的确定方式。当多个上行信息包括更多个上行信息时,该多个上行信息关联的频域资源的确定方式类似,这里不再赘述。
实施例1:非使能跳频,频域资源分配的粒度为RBG。
在一些实施例中,是否使能跳频可以是根据DCI中是否包括跳频标识,或者,跳频标识的状态确定的。
例如,若DCI不包括跳频标识(即跳频标识为0比特),确定非使能跳频,或者说,未使能跳频,或者,若DCI中包括跳频标识(例如包括1比特的跳频标识),确定使能跳频。
又例如,若DCI中包括跳频标识(例如为1比特),并且跳频标识的状态为‘非使能(disable)’,确定非使能跳频;或者,若DCI中包括跳频标识(例如为1比特),并且跳频标识的状态为‘使能(enable),确定使能跳频。
在一些实施例中,根据RRC信令的配置确定是否使能跳频,或者多个上行信息的频域资源为跳频资源还是非跳频资源。
在该实施例1中,DCI中不包括跳频标识,或者,包括跳频标识,但跳频标识的状态为disable。
可选地,在该实施例1中,DCI的格式可以是DCI格式0_0,格式0_1,格式0_2。
在非使能跳频的情况下,频域资源分配信息所分配的资源为非跳频资源,即第一频域资源和第二频域资源为非跳频资源。
在一些实施例中,频域资源的分配粒度是网络设备指示的。
例如,在配置的资源分配方式为资源分配类型0的情况下,频域资源的分配粒度为RBG。
又例如,在配置的资源分配方式为资源分配类型1的情况下,频域资源的分配粒度为RB。
在一些实施例中,第一频域资源属于第一RBG集合,第二频域资源属于第二RBG集合,其中,第一RBG集合包括的RBG数和第二RBG集合包括的RBG数根据资源分配系数确定。
在一些实施例中,第一RBG集合关联第一空间参数,第二RBG集合关联第二空间参数。
换言之,第一RBG集合中的频域资源可以用于传输关联第一空间参数的上行信息,第二RBG集合中的频域资源可以用于传输关联第二空间参数的上行信息。
在一些实施例中,第一RBG集合包括的RBG数可以根据资源分配系数和第一RBG数K
RBG确定,第一RBG集合包括的RBG数和第二RBG集合包括的RBG数之和为第一RBG数K
RBG。
可选地,第一RBG集合包括的RBG数可以根据资源分配系数和第一RBG数K
RBG的乘积确定,例如,将资源分配系数和第一RBG数K
RBG的乘积取整得到第一RBG集合包括的RBG数。可选地,这里的取整可以是向上取整,或者,也可以是向下取整,或者,也可以是四舍五入。
情况1:第一RBG数K
RBG为上行带宽部分(Band Width Part,BWP)包括的RBG的总数N
RBG。
在情况1中,第一频域资源为第一RBG集合中用于上行传输的RBG中的频域资源,第二频域资源为所述第二RBG集合中用于上行传输的RBG中的频域资源。
在一些实施例中,频域资源分配信息通过比特位图(bitmap)方式指示上行BWP包括的所有RBG中的可用于上行传输的RBG,则第一频域资源可以为第一RBG集合中bitmap状态为可用于上行传输的RBG中的频域资源,第二频域资源可以为第二RBG集合中bitmap状态为可用于上行传输的RBG中的频域资源。
例如,频域资源分配信息通过第一比特位图表示,第一比特位图包括多个比特位,每个比特位对应一个RBG,则该多个比特位的个数为N
RBG,对应上行BWP包括的N
RBG个RBG,每个比特位的取值为第一值(例如取值为1)用于指示对应的RBG可用于上行传输,取值为第二值(例如取值为0)用于指示对应的RBG不用于上行传输。其中,多个比特位包括第一比特位组和第二比特位组,第一比特位组对应的RBG组成所述第一RBG集合,第二比特位组对应的RBG组成所述第二RBG集合。则第一频域资源为第一比特位组中取值为第一值的比特位对应的RBG中的频域资源,第二频域资源为第二比特位组中取值为第一值的比特位对应的RBG中的频域资源。
如图4所示,以示例1,第一值为1举例说明,第一RBG集合包括
个RBG,第二RBG集合包括
个RBG。进一步地,确定第一频域资源为第一RBG集合中bitmap状态为1的RBG中的频域资源,第二频域资源为第二RBG集合中bitmap状态为1的RBG中的频域资源。
对应地,网络设备也可以根据资源分配系数和频域资源分配信息确定第一频域资源和/或第二频域资源,其中,频域资源分配信息采用bitmap的方式,若bitmap的状态为1,则该RBG用于上行传输,否则不用于上行传输,其中,网络设备分配的可用于上行传输的RBG可以是连续的,也可以是不连续的。例如,若上行BWP包括的RB数为48,RBG大小采用如下表1中的配置2,通过表1可以得到,一个RBG包括的RB数为8个RB,则该上行BWP包括的总RBG数为6个RBG,即N
RBG=6,若r1为1/3,则第一RBG集合包括
个RBG,第二RBG集合包括4个RBG。其中,第一RBG集合包括RBG0和RBG1,第二RBG集合包括RBG2~RBG5。
表1
BWP大小 | 配置1 | 配置2 |
1–36 | 2 | 4 |
37–72 | 4 | 8 |
73–144 | 8 | 16 |
145–275 | 16 | 16 |
进一步按照bitmap状态确定第一频域资源和第二频域资源,如图5所示。若第一RBG集合中的RBG1对应的bitmap状态为1,则第一频域资源可以包括RBG1中的频域资源,若第二RBG集合中 的RBG3和RBG4对应的bitmap状态为1,则第二频域资源可以包括RBG3和RBG4中的频域资源。
情况2:第一RBG数K
RBG为上行BWP包括的RBG中可用于上行传输的RBG的总数。
例如,第一RBG数是上行BWP包括的RBG中bitmap状态为1的RBG的总数N'
RBG。
即在情况2中,第一RBG集合和第二RBG集合包括的RBG数是网络设备实际分配的可用于上行传输的RBG数。也就是说,第一RBG集合和第二RBG集合中的频域资源均可以用于上行传输。
进一步地,第一频域资源可以包括第一RBG集合中的RBG中的频域资源,第二频域资源可以包括第二RBG集合中的RBG中的频域资源。
接着上述示例,在该情况2中,如图6所示,该第一RBG集合可以包括RBG1,第二RBG集合可以包括RBG3和RBG4,则第一频域资源可以包括RBG1中的频域资源,第二频域资源可以包括RBG3和RBG4中的频域资源。
综上,在实施例1中,提出了非跳频场景中资源分配粒度为RBG情况下的频域资源分配方法,通过根据资源分配系数划分频域资源,进一步地,通过该频域资源发送与空间参数关联的上行信息,不需要在DCI或RRC中添加新的字段,有利于减少DCI或RRC信令的比特开销。

其中,是否使能跳频的判断方式参考实施例1的相关描述,为了简洁,这里不再赘述。

可选地,在该实施例2中,DCI的格式可以是DCI格式0_0,格式0_1,格式0_2。
在该实施例2中,在配置的资源分配方式为资源分配类型1的情况下,频域资源分配的粒度为RB。
在一些实施例中,第一频域资源包括的RB数和第二频域资源包括的RB数根据资源分配系数确定。
在一些实施例中,第一频域资源包括的RB数可以根据资源分配系数和频域资源分配信息所分配的资源包括的RB总数确定,第二频域资源包括的RB数和第一频域资源包括的RB数可以为频域资源分配信息所分配的资源包括的RB总数。
可选地,第一频域资源包括的RB数可以根据资源分配系数和频域资源分配信息所分配的资源包括的RB总数的乘积确定,例如将资源分配系数和频域资源分配信息所分配的资源包括的RB总数的乘积取整得到第一频域资源包括的RB数,可选地,这里的取整可以是向上取整,或者,也可以是向下取整,或者,也可以是四舍五入。
应理解,在本申请实施例中,RB可以指RB的中心频点,或者是RB的起始频域位置,或者RB的结束频域位置。
可选地,对于波形为离散傅立叶变换-扩频-正交频分复用(Discrete Fourier Transform-Spread-Orthogonal Frequency Division Multiplexing,DFT-S-OFDM),第一频域资源和第二频域资源包括连续的或非连续的RB;对于波形为循环前缀-正交分频复用(Cyclic Prefix-Orthogonal Frequency Division Multiplexing,CP-OFDM)波形,第一频域资源和第二频域资源包括连续的或近似连续的RB。

可选地,第一频域资源包括的RB数可以根据资源分配系数和频域资源分配信息所分配的资源包括的RB总数的乘积确定,例如,将资源分配系数和频域资源分配信息所分配的资源包括的RB总数的乘积取整得到第一频域资源包括的RB数,可选地,这里的取整可以是向上取整,或者,也可以是向下取整,或者,也可以是四舍五入。
在一些实施例中,第一跳频资源和第二跳频资源包括的RB数之和为第一频域资源包括的RB数。
在一些实施例中,第一跳频资源可以为第一频域资源包括的RB数的1/2,例如,将第一频域资源包括的RB数乘以1/2取整后得到第一跳频资源包括的RB数,其中,取整可以是向上取整,或者,也可以是向下取整,或者,也可以是四舍五入。
在一些实施例中,第三跳频资源和第四跳频资源包括的RB数之和为第二频域资源包括的RB数。

在一些实施例中,第三跳频资源的起始位置根据第一跳频资源的起始位置,频域资源分配信息以及资源分配系数确定。
在一些实施例中,第四跳频资源的起始位置根据第二跳频资源的起始位置,频域资源分配信息以及资源分配系数确定。

在本申请实施例中,计算第三跳频资源和第四跳频资源的频域资源时可以不固定采用第一跳频资源和第二跳频资源包括的RB数,而是可以灵活选择特定的RE偏移,有利于提升用于传输上行信息的频域资源位置的灵活性。
