Description

一种通信方法、装置及***
本申请要求于2020年4月10日提交国家知识产权局、申请号为202010281143.X、申请名称为“一种通信方法、装置及***”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
本申请涉及通信技术领域,尤其涉及一种通信方法、装置及***。
背景技术
第五代(the fifth-generation,5G)移动通信技术,是基于正交频分复用(orthogonal frequency division multiplexing,OFDM)的全新空口设计的全球性5G标准,也是下一代非常重要的蜂窝移动技术基础。其中,5G移动通信技术的业务具备多样化,包括增强型移动宽带(enhanced Mobile Broadband,eMBB)业务、超可靠低延时通信(ultra-reliability low-latency communication,URLLC)业务以及大规模机器通信(massive machine-type communication,mMTC)业务。一般而言,mMTC终端设备(也可以称之为机器类终端设备)相对于eMBB终端设备有更高的功耗需求。基于此,在第三代合作伙伴计划(3rd generation partnership project,3GPP)新无线(new radio,NR)版本17(release 17)中,降低能力的NR(NR reduced capability,NR REDCAP)终端设备作为mMTC终端设备的一种,其研究正受到越来越多的关注。
如何节省NR REDCAP终端设备的功耗?考虑到目前终端设备检测网络设备发送的下行控制信息(downlink control information,DCI)必然会消耗一部分功耗,因此可以通过降低NR REDCAP终端设备检测网络设备发送的DCI的功耗的方式来节省NR REDCAP终端设备的功耗。然而,如何降低终端设备检测DCI的功耗,目前并没有相关的解决方案。
发明内容
本申请实施例提供一种通信方法、装置及***,用于降低终端设备检测DCI的功耗。
为达到上述目的,本申请的实施例采用如下技术方案:
第一方面,提供了一种通信方法,该方法适用于通信装置,该通信装置例如为终端设备,该方法包括:接收来自网络设备的第一下行控制信息DCI,该第一DCI用于上行或下行数据调度,其中,该第一DCI的比特数固定,该第一DCI包括第一标识,该第一标识用于指示该第一DCI的格式,该第一DCI的格式包括第一DCI格式或第二DCI格式;根据该第一DCI,接收来自该网络设备的下行数据或者向该网络设备发送上行数据。基于该方案,由于第一DCI的比特数固定,并且第一DCI具有多种DCI格式,也就是说,可以针对多种格式的DCI设计一种DCI size(也可以称之为DCI比特数),因此不仅可以降低终端设备检测DCI的复杂度,从而节省终端设备的功耗,而且可以保证数据传输的多样性,增加调度的灵活性。
第二方面,提供了一种通信方法,该方法适用于通信装置,该通信装置例如为网 络设备,该方法包括:确定第一下行控制信息DCI,该第一DCI用于上行或下行数据调度,其中,该第一DCI的比特数固定,该第一DCI包括第一标识,该第一标识用于指示该第一DCI的格式,该第一DCI的格式包括第一DCI格式或第二DCI格式;向终端设备发送该第一DCI。基于该方案,由于第一DCI的比特数固定,并且第一DCI具有多种DCI格式,也就是说,可以针对多种格式的DCI设计一种DCI size(也可以称之为DCI比特数),因此不仅可以降低终端设备检测DCI的复杂度,从而节省终端设备的功耗,而且可以保证数据传输的多样性,增加调度的灵活性。
结合第一方面或第二方面,在一种可能的实现方式中,具有第二DCI格式的该第一DCI包括的信息域中存在至少一个信息域的信息比特数大小是可配置的,例如可以通过RRC信令配置,从而可以增加调度的灵活性。
结合第一方面或第二方面,在一种可能的实现方式中,具有第一DCI格式的该第一DCI包括的每个信息域的比特数均大小固定。
结合第一方面或第二方面,在一种可能的实现方式中,该第一DCI的比特数固定,包括:该第一DCI中包括的每个信息域的比特数均大小固定;或者,该第一DCI中包括与无线资源控制RRC信令配置关联的信息域,但该第一DCI对应的比特数大小固定;或者,该第一DCI对应的比特数大小与初始接入参数相关。也就是说,上述方式均可以视为第一DCI的比特数固定。
结合第一方面或第二方面,在一种可能的实现方式中,该第一DCI的比特数与第二DCI的比特数相同,其中,该第二DCI用于调度公共信息传输。也就是说,考虑到终端设备在与网络设备建立数据传输链路之前,会检测网络设备传输的公共信息(例如网络设备广播的***信息),进而获取网络设备的基本配置信息。并且网络设备传输的公共信息也可以通过DCI调度方式实现,即网络设备可以通过DCI指示调度公共信息传输的控制信息,终端设备通过检测该DCI,可以确定调度公共信息传输的控制信息,并根据该控制信息接收网络设备传输的公共信息。因此本申请实施例中,可以将第一DCI的比特数设计的与调度公共信息传输的第二DCI的比特数相同,从而可以进一步降低终端设备检测的具有不同DCI size的DCI个数,进而节省终端设备的功耗。
结合第一方面或第二方面,在一种可能的实现方式中,该公共信息对应的终端设备为第一类型终端设备;或者,该公共信息对应的终端设备包括该第一类型终端设备和第二类型终端设备,其中,该第一类型终端设备与该第二类型终端设备的能力不同。例如,该第一类型终端设备的能力小于该第二类型终端设备的能力。基于该方案,当公共信息对应的终端设备可以包括第一类型终端设备和第二类型终端设备时,也意味着第一类型终端设备和第二类型终端设备可以接收相同的公共信息,进而第一类型终端设备和第二类型终端设备接收到的用于调度公共信息传输的第二DCI是相同的。从网络设备侧而言,采用这样的设计,可以针对不同类型的终端设备发送相同的DCI用于指示公共信息传输,可以降低网络设备发送公共信息的开销(公共信息的开销包括调度公共信息传输的DCI对应的资源开销,或者,公共信息的开销包括调度公共信息传输的DCI和公共信息传输对应的资源开销),进而节省网络设备侧功耗。
结合第一方面或第二方面,在一种可能的实现方式中,当该公共信息为***信息时,该第二DCI包括调度***信息块类型1或者其他***信息的控制信息,其中,该 第二DCI通过***信息无线网络临时标识SI-RNTI加扰;或者,该公共信息为寻呼消息,该第二DCI通过寻呼无线网络临时标识P-RNTI加扰;或者,该公共信息为随机接入响应RAR信息,该第二DCI通过随机接入无线网络临时标识RA-RNTI加扰。也就是说,本申请实施例中,对于不同的公共信息,可以使用不同的RNTI进行区分。
结合第一方面或第二方面,在一种可能的实现方式中,该第一DCI的比特数与第二DCI的比特数相同,包括:该第一DCI包括的所有信息域的比特数总和与该第二DCI包括的所有信息域的比特数总和相同;或者,该第一DCI的原始信息比特数与该第二DCI的原始信息比特数相同,其中,该原始信息比特数为DCI传输在执行循环冗余校验CRC操作之前的比特数;或者,该第一DCI在执行信道编码操作之前的比特数与该第二DCI在执行信道编码操作之前的比特数相同;或者,该第一DCI对应传输的调制符号个数与该第二DCI对应传输的调制符号个数相同;或者,该第一DCI对应传输的调制符号在解调之后对应的比特数与该第二DCI对应传输的调制符号在解调之后对应的比特数相同。也就是说,上述方式均可以视为第一DCI的比特数与第二DCI的比特数相同。
结合第一方面或第二方面,在一种可能的实现方式中,具有该第一DCI格式的第一DCI包括如下一项或多项信息域:第一信息域,该第一信息域用于指示频域资源分配信息;第二信息域,该第二信息域用于指示时域资源分配信息;第三信息域,该第三信息域用于指示调制编码方案MCS;第四信息域,该第四信息域用于指示冗余版本RV指示;或者第五信息域,该第五信息域用于指示混合自动重传HARQ进程编号。
结合第一方面或第二方面,在一种可能的实现方式中,当第一DCI用于下行数据调度时,具有该第一DCI格式的第一DCI还包括如下一项或多项信息域:第六信息域,该第六信息域用于指示调度物理上行控制信道PUCCH的传输功率控制TPC信息;第七信息域,该第七信息域用于指示PUCCH资源;或者第八信息域,该第八信息域用于指示该第一DCI调度的下行数据传输与HARQ反馈之间的定时关系。

结合第一方面或第二方面,在一种可能的实现方式中,第二数据传输功能的信息域是否生效通过具有该第二DCI格式的该第一DCI中的控制字段以位图或者二进制的方式指示,其中,生效的信息域对应的参数信息由RRC信令配置。在本申请实施例中,针对具有第二DCI格式的第一DCI,当信息域的具体配置参数通过RRC配置实现时,该RRC配置信令可以通过具有第一DCI格式的第一DCI所调度的PDSCH承载。由于具有第一DCI格式的第一DCI对应的信息域比特数是确定的,因此终端设备可以通过检测第一DCI格式,确定第一DCI所指示的调度信息,进而接收PDSCH获取RRC配置信令,终端设备在检测具有第一DCI格式的第一DCI时,也不存在RRC信令配置模糊的问题。
结合第一方面或第二方面,在一种可能的实现方式中,在该终端设备对应的用户搜索空间USS内仅配置具有该第一DCI比特数大小的DCI格式。由于在USS中仅配置具有第一DCI比特数大小的DCI格式,因此终端设备在该USS内只需要检测一种DCI size的DCI格式,相比于现有技术中,终端设备在USS内最多检测两种DCI size的DCI格式,采用本方案,可以降低终端设备检测DCI的复杂度,从而节省终端设备的功耗。
结合第一方面或第二方面,在一种可能的实现方式中,在该终端设备对应的USS和公共搜索空间CSS内仅配置具有该第一DCI比特数大小的DCI格式。对于终端设备而言,当在被配置的所有USS和所有CSS内,仅配置具有第一DCI比特数大小的DCI格式时,该终端设备最多只需要检测1种DCI size的DCI格式,相比于现有技术中终端设备在CSS和USS内最多检测4种DCI size的DCI格式,采用本方案,可以降低终端设备检测DCI的复杂度,从而节省终端设备的功耗。

具体实施方式
为了方便理解本申请实施例的技术方案,首先给出本申请相关技术的简要介绍如 下。
目前,终端设备一般通过接收网络设备发送的DCI,确定和网络设备进行数据传输的必要信息。例如,终端设备可以通过接收网络设备发送的公共控制信息,确定网络设备发送的公共信息。又例如,终端设备可以通过接收网络设备发送的该终端设备特定的控制信息,和网络设备之间完成数据传输。这里的数据传输包括上行数据传输和/或下行数据传输。通常,网络设备发送的公共控制信息,通过公共无线网络临时标识(radio network temporary identity,RNTI)加扰,该公共控制信息可以是小区特定公共信息,也可以是用户组公共信息,二者之间的区别在于:前者对于小区内的所有终端设备都有效,而后者只对一组特定终端设备有效。网络设备发送的终端设备特定的控制信息,通过该终端设备特定的RNTI加扰。
终端设备检测网络设备发送的DCI,必然会消耗一部分功耗,一般而言,终端设备会在一些备选的资源上检测是否存在自己需要接收的DCI,该终端设备需要接收的DCI包括但不限于:网络设备发送的小区特定公共控制信息、用户组特定公共控制信息以及该终端设备特定的控制信息。为了便于描述,备选的资源可以用物理下行控制信道备选(physical downlink control channel candidates,PDCCH candidates)表示,这是因为DCI一般都通过PDCCH承载,因此发送DCI的备选资源可以通过PDCCH candidates表示。此外,终端设备在一个备选资源上,也有可能会检测多个DCI,多个DCI可以按照DCI大小(DCI size)进行分类。其中,对于具有相同DCI size的DCI,由于可以通过不同的RNTI来区分,所以可以认为终端设备在该备选资源上针对该DCI size只需要检测一次,就可以确定网络设备发送的控制信息;另一方面,对于具有不同DCI size的DCI,终端设备在该备选资源上需要检测的DCI个数与具有不同DCI size的DCI个数相同。需要说明的是,这里的DCI size包括网络设备发送的原始信息元素,或者包括原始信息元素与循环冗余校验(cyclic redundancy check,CRC)位。
根据如上描述,可以获知:终端设备检测DCI所消耗的功耗与发送DCI的备选资源个数以及DCI大小(size)的个数有关,一般而言,发送DCI的备选资源个数越多,需要检测的不同DCI size的个数越多,终端设备检测DCI所消耗的功耗就越大。
现有技术中,假设终端设备在小区A上检测DCI(也可以认为是检测PDCCH),则终端设备被配置检测的不同DCI size的最大个数为4。其中,终端设备在小区A的一个下行带宽部分(bandwidth part,BWP),根据不同的子载波间隔(subcarrier spacing,SCS),检测DCI的最大盲检测次数如表一所示:
表一
SCS 最多盲检次数
15KHz 44
30KHz 36
60KHz 22
120KHz 20
由此可以看出,现有技术中,不同DCI size的个数较多,导致盲检测次数较多。若直接将现有技术应用到NR REDCAP终端设备的DCI检测过程中,不利于NR REDCAP终端设备的功耗节省。
为降低终端设备检测DCI的功耗,下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行描述。
本申请实施例可以适用于长期演进(long term evolution,LTE)***或NR***(也可以称之为5G***),也可以适用于其他面向未来的新***等,本申请实施例对此不作具体限定。此外,术语“***”可以和“网络”相互替换。
如图1所示,为本申请实施例提供的一种通信***10。该通信***10包括网络设备20,以及与该网络设备20连接的一个或多个终端设备30。其中,终端设备30通过无线的方式与网络设备20相连。可选的,不同的终端设备30之间可以相互通信。终端设备30可以是固定位置的,也可以是可移动的。
需要说明的是,图1仅是示意图,虽然未示出,但是该通信***10中还可以包括其它设备,例如该通信***10还可以包括核心网设备、无线中继设备和无线回传设备中的一个或多个,在此不做具体限定。其中,网络设备20可以通过无线或有线方式与核心网设备连接。核心网设备与网络设备20可以是独立的不同的物理设备,也可以是将核心网设备的功能与网络设备20的逻辑功能集成在同一个物理设备上,还可以是一个物理设备上集成了部分核心网设备的功能和部分的网络设备20的功能,本申请实施例对此不做具体限定。
以图1所示的网络设备20与任一终端设备30进行交互为例,本申请实施例中,网络设备20确定第一DCI之后,向终端设备30发送第一DCI。相应的,终端设备30接收来自网络设备20的第一DCI。其中,第一DCI用于上行或下行数据调度,第一DCI的比特数固定,第一DCI包括第一标识,第一标识用于指示第一DCI的格式,第一DCI的格式包括第一DCI格式或第二DCI格式。进而,终端设备30根据第一DCI,接收来自网络设备20的下行数据或者向网络设备20发送上行数据。其中,该方案的具体实现将在后续方法实施例中详细描述,在此不予赘述。基于该方案,由于第一DCI的比特数固定,并且第一DCI具有多种DCI格式,也就是说,可以针对多种格式的DCI设计一种DCI size,因此不仅可以降低终端设备检测DCI的复杂度,从而节省终端设备的功耗,而且可以保证数据传输的多样性,增加调度的灵活性。
可选的,本申请实施例中的网络设备20,是一种将终端设备30接入到无线网络的设备,可以是基站(base station)、演进型基站(evolved NodeB,eNodeB)、发送接收点(transmission reception point,TRP)、5G移动通信***中的下一代基站(next generation NodeB,gNB)、未来移动通信***中的基站或无线保真(wireless-fidelity,Wi-Fi)***中的接入节点等;也可以是完成基站部分功能的模块或单元,例如,可以是集中式单元(central unit,CU),也可以是分布式单元(distributed unit,DU)。本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。在本申请中,如果无特殊说明,网络设备均指无线接入网设备。

如图4所示,为本申请实施例提供的一种通信方法,该通信方法包括如下步骤S401至S403。
S401、网络设备确定第一DCI。其中,第一DCI用于上行或下行数据调度,第一DCI的比特数固定,第一DCI包括第一标识,第一标识用于指示第一DCI的格式,第一DCI的格式包括第一DCI格式或第二DCI格式。
S402、网络设备向终端设备发送第一DCI。相应的,终端设备接收来自网络设备的第一DCI。
S403、终端设备根据第一DCI,与网络设备进行上行或下行数据传输,如接收来自网络设备的下行数据或者向网络设备发送上行数据。
下面将对上述步骤S401-S403具体说明如下:
本申请实施例中,第一DCI用于上行数据传输调度,可以理解为第一DCI包括上行数据传输的调度信息(简称上行调度信息);第一DCI用于下行数据传输调度,可以理解为第一DCI包括下行数据传输的调度信息(简称下行调度信息)。具体的,该第一DCI是用于上行数据传输调度还是用于下行数据传输调度,可以通过第一DCI中包括的信息域显式或隐式指示。
例如,可以通过第一DCI中包括的1bit不同取值分别表示该第一DCI用于上行或下行数据传输调度。示例性的,该1bit取值为0表示该第一DCI用于上行数据传输调度,该1bit取值为1表示该第一DCI用于下行数据传输调度;或者,该1bit取值为1 表示该第一DCI用于下行数据传输调度,该1bit取值为0表示该第一DCI用于上行数据传输调度。
又例如,可以复用第一DCI包括的信息域的特殊状态来表示该第一DCI用于上行或下行数据传输调度。示例性的,第一控制信息中包括的某个信息域对应M个比特,这M个比特一共可以表示2^M(2的M次幂)种状态,可以通过2^M种状态中的部分状态指示该第一DCI用于上行或下行数据传输调度。具体的,比如,可以通过M个比特全部取值为1表示该第一DCI用于上行数据传输调度,M个比特全部取值为0表示该第一DCI用于下行数据传输调度;或者,可以通过M个比特全部取值为1表示该第一DCI用于下行数据传输调度,M个比特全部取值为0表示该第一DCI用于上行数据传输调度。其中,第一DCI中的信息域可以理解为实现数据传输功能的信息比特域,例如用于指示数据传输所使用的频率资源,或者用于指示数据传输所使用的时域资源等。
本申请实施例中,第一DCI为终端设备特定的DCI。终端设备特定的DCI,可以理解为该第一DCI只对该终端设备有效。其中,例如可以采用该终端设备对应的小区无线网络临时标识(cell-Radio network temporary identifier,C-RNTI)加扰第一DCI。当然,也可以采用其它方式加扰第一DCI,本申请实施例对此不做具体限定。其中,本申请实施例中,采用该终端设备对应的C-RNTI加扰第一DCI,可以理解为C-RNTI可以通过扰码的方式作用到该第一DCI的CRC奇偶校验位上,在此统一说明,以下不再赘述。
本申请实施例中,第一DCI的比特数固定,可以理解为第一DCI的比特数大小(payload size)固定。示例性的,可以包括以下至少一种理解:
1)、第一DCI中包括的每个信息域对应的比特数大小都是固定值,不随着无线资源控制(radio resource control,RRC)信令配置参数的不同而不同。例如,当第一DCI中的信息域用于指示传输数据的时间资源时,对应的比特数为4比特,即使网络设备通过RRC信令配置不同的时间资源参数,该信息域的比特数仍为4比特。
2)、第一DCI中包括与RRC信令配置关联的信息域,但第一DCI对应的比特数大小固定。例如,第一DCI中共包括3个不同的信息域,分别用来指示传输数据的频率资源、传输数据的时域资源以及调制编码方案(modulation coding scheme,MCS)。其中,这3个不同的信息域对应的比特数都可以根据RRC信令配置确定。例如,网络设备通过RRC信令配置16种频率资源用于传输数据,则第一控制信息中用于指示传输数据的频率资源的信息域可以对应4比特;又例如,网络设备通过RRC信令配置8种频率资源用于传输数据,则第一控制信息中用于指示传输的频率资源的信息域可以对应3比特。此时,尽管用于指示传输数据的频率资源的信息域对应的比特数可以改变,但要保证第一DCI对应的比特数大小固定。
3)、第一DCI对应的比特数大小与初始接入参数相关。换言之,第一DCI对应的比特数大小可变,但是具体取值(或者说第一DCI对应的比特数大小的可变范围)只与初始接入参数有关,一旦初始接入参数确定,第一DCI对应的比特数大小即固定。
可选的,本申请实施例中,初始接入参数例如为同步信号块(synchronization signal block,SSB)包括的信息。示例性的,SSB包括的信息例如可以为SSB索引信息或者 SSB包括的物理广播信道(physical broadcast channel,PBCH)所承载的控制信息即主信息块(master information block,MIB)所指示的信息。具体的,SSB索引信息例如可以SSB时间索引(SSB time index),MIB所指示的信息例如可以包括:MIB中通过PDCCH配置***信息块类型1(pdcch-ConfigSIB1)指示的信息,或者MIB中包括的控制资源集合0(control resource set#0,CORESET#0)的配置信息等。其中,CORESET#0频率资源对应初始带宽部分(initial bandwidth part,initial BWP)的频率资源,CORESET#0时间资源对应包括调度公共信息传输的控制信息的时间资源,例如可以用调度公共信息传输的控制信息对应的搜索空间(search space,SS)表示,公共信息传输例如可以是网络设备广播的***信息(system information,SI)、网络设备广播的寻呼信息(paging message)、网络设备广播的随机接入响应(random access response,RAR)。例如,当CORESET#0频率资源分别对应24个资源块(resource block,RB)、48个RB、96个RB时,第一DCI对应的比特数大小可以分别为X1个比特、X2个比特、X3个比特,其中X1≤X2≤X3。
或者,可选的,本申请实施例中,初始接入参数例如为该终端设备的带宽能力。例如,当终端设备的带宽能力分别为5MHz、10MHz、20MHz时,第一DCI对应的比特数大小可以分别为Y1个比特、Y2个比特、Y3个比特,其中Y1≤Y2≤Y3。
可选的,本申请实施例中,可以设计第一DCI的比特数与第二DCI的比特数相同,其中,第二DCI用于调度公共信息传输。这里的公共信息如上所述,可以包括:网络设备广播的SI、寻呼信息或者RAR等。也就是说,考虑到终端设备在与网络设备建立数据传输链路之前,会检测网络设备传输的公共信息(例如网络设备广播的SI),进而获取网络设备的基本配置信息。并且网络设备传输的公共信息也可以通过DCI调度方式实现,即网络设备可以通过DCI指示调度公共信息传输的控制信息,终端设备通过检测该DCI,可以确定调度公共信息传输的控制信息,并根据该控制信息接收网络设备传输的公共信息。因此本申请实施例中,可以将第一DCI的比特数设计的与调度公共信息传输的第二DCI的比特数相同,从而可以进一步降低终端设备检测的具有不同DCI size的DCI个数,进而节省终端设备的功耗。可选的,本申请实施例中,终端设备可以通过不同的RNTI区分第一DCI与第二DCI。
其中,当公共信息为网络设备广播的SI时,第二DCI包括调度SIB1或者其他***信息的控制信息,其他***信息例如可以为SIB2、SIB3等。此外,第二DCI还可以包括无线网络临时标识(system information radio network temporary identifier,SI-RNTI),例如第二DCI可以通过***信息SI-RNTI加扰实现。
或者,当公共信息为网络设备广播的寻呼消息时,第二DCI可以包括寻呼无线网络临时标识(paging radio network temporary identifier,P-RNTI),例如第二DCI可以通过P-RNTI加扰实现。
或者,当公共信息为网络设备广播的RAR信息时,第二DCI可以包括随机接入无线网络临时标识(random access radio network temporary identifier,RA-RNTI),例如第二DCI可以通过RA-RNTI加扰实现。
可选的,本申请实施例中,公共信息对应的终端设备可以为第一类型终端设备,即只有第一类型终端设备可以解析该公共信息;或者,公共信息对应的终端设备可以 包括第一类型终端设备和第二类型终端设备,即第一类型终端设备和第二类型终端设备均可以解析该公共信息。其中,第一类型终端设备与第二类型终端设备的能力不同,图4中与网络设备交互的终端设备为第一类型终端设备。
可选的,本申请实施例中,第一类型终端设备与第二类型终端设备的能力不同可以包括以下至少一种理解:
a)、第一类型终端设备的带宽能力与第二类型的终端设备的带宽能力不同。可选的,第一类型终端设备的带宽能力小于第二类型的终端设备的带宽能力。例如,第二类型终端设备最大可以支持在一个载波上同时使用带宽为100MHz的频率资源和网络设备进行数据传输;而第一类型终端设备最大可以支持在一个载波上同时使用带宽为20MHz或者10MHz或者5MHz的频率资源和网络设备进行数据传输。
b)、第一类型终端设备的收发天线数与第二类型的终端设备的收发天线数不同。可选的,第一类型终端设备的收发天线数小于第二类型的终端设备的收发天线数。例如,第二类型终端设备可以支持4收2发,或者4收1发;而第一类型终端设备最大支持2收1发,或者最大支持1收1发。
c)、第一类型终端设备的上行最大发射功率与第二类型的终端设备的上行最大发射功率不同。可选的,第一类型终端设备的上行最大发射功率小于第二类型的终端设备的上行最大发射功率。例如,第二类型终端设备的上行最大发射功率可以为23dBm或者26dBm,而第一类型终端设备的上行最大发射功率只能为4dBm~20dBm中的一个值。

e)、第一类型终端设备的载波聚合能力与第二类型终端设备的载波聚合能力不同。可选的,第一类型终端设备的载波聚合能力小于第二类型终端设备的载波聚合能力。例如,第二类型终端设备支持载波聚合;而第一类型终端设备不支持载波聚合。又例如,第一类型终端设备和第二类型终端设备均支持载波聚合,但是第二类型终端设备同时支持的载波聚合的最大个数大于第一类型终端设备同时支持的载波聚合的最大个数,如第二类型终端设备可以最多同时支持5个载波或者32个载波的聚合,而第一类型终端设备最多同时支持2个载波的聚合。
f)、第一类型终端设备的双工能力与第二类型终端设备的双工能力不同。可选的,第一类型终端设备的双工能力小于第二类型终端设备的双工能力。例如,第二类型终端设备可以支持全双工频分双工(frequency division duplexing,FDD),或者既支持全双工FDD也支持半双工FDD;而第一类型终端设备仅支持半双工FDD。
g)、第一类型终端设备对数据的处理时间能力与第二类型终端设备对数据的处理时间能力不同。可选的,第一类型终端设备对数据的处理时间能力小于第二类型终端设备对数据的处理时间能力。其中,本申请实施例中,对数据的处理时间能力不同可 以通过两类终端设备处理数据的最小时延之间的关系来表示,也可以通过两类终端设备处理数据的最大时延之间的关系来表示,或者也可以通过一类终端设备处理数据的最小时延与另外一类终端设备处理数据的最大时延之间的关系来表达。其中,数据处理的时延又可以用如下至少一种方式表示:接收下行数据与发送对该下行数据的混合自动重传请求(hybrid automatic repeat request,HARQ)反馈之间的时延,发送上行数据与接收对该上行数据的HARQ反馈之间的时延,或者接收控制信息与根据该控制信息发送上行数据之间的时延。例如,第二类型终端设备接收下行数据与发送对该下行数据的HARQ反馈之间的最小时延小于第一类型终端设备接收下行数据与发送对该下行数据的HARQ反馈之间的最小时延,和/或,第二类型终端设备发送上行数据与接收对该上行数据的HARQ反馈之间的最小时延小于第一类型终端设备发送上行数据与接收对该上行数据的HARQ反馈之间的最小时延,和/或,第二类型终端设备接收控制信息与根据该控制信息发送上行数据之间的最小时延小于第一类型终端设备接收控制信息与根据该控制信息发送上行数据之间的最小时延。
h)、第一类型终端设备的处理能力与第二类型终端设备的处理能力不同。可选的,第一类型终端设备的处理能力小于第二类型终端设备的处理能力。本申请实施例中,终端设备的处理能力包括但不限于以下至少一项:上行数据传输和/或下行数据传输所支持的HARQ进程个数,软缓存(soft buffer)大小,上行数据传输和/或下行数据传输所支持的最高正交振幅调制(quadrature amplitude modulation,QAM)等。
i)、第一类型终端设备对应的上行数据传输峰值速率和/或下行数据传输峰值速率与第二类型终端设备对应的上行数据传输峰值速率和/或下行数据传输峰值速率不同。可选的,第一类型终端设备对应的上行数据传输峰值速率和/或下行数据传输峰值速率小于第二类型终端设备对应的上行数据传输峰值速率和/或下行数据传输峰值速率。
示例性的,本申请实施例中,第一类型终端设备可以为NR-light终端设备、第二类型终端设备可以为非NR-Light终端设备或者为兼具NR-light与非NR-light功能的终端设备(例如,NR release 15,和/或NR release 16的终端设备,也可以是未来无线通信***中演进的终端设备,不限于LTE终端设备、以及NR终端设备)。
或者,示例性的,第一类型终端设备和第二类型终端设备也可以同时为NR-light终端设备,但是第一类型终端设备的能力小于第二类型终端设备的能力,关于两种类型终端设备能力之间的比较可以参考上述描述,不做赘述。比如,第二类型终端设备在一个载波上的数据传输带宽最大可以为20MHz;而第一类型终端设备在一个载波上的数据传输带宽最大为10MHz。
或者,示例性的,第一类型终端设备可以为NR REDCAP终端设备;第二类型终端设备可以为非NR REDCAP终端设备。按照协议版本划分,本申请实施例中,可以将上述的NR Legacy终端设备看为非NR REDCAP终端设备,将NR release 17和/或NR release 17之后版本的部分终端设备视为NR REDCAP终端设备,例如具备NR REDCAP能力的终端设备,或者同时具备非NR REDCAP能力和NR REDCAP能力的终端设备。
其中,本申请实施例中,当公共信息对应的终端设备可以包括第一类型终端设备和第二类型终端设备时,也意味着第一类型终端设备和第二类型终端设备可以接收相 同的公共信息,进而第一类型终端设备和第二类型终端设备接收到的用于调度公共信息传输的第二DCI是相同的。从网络设备侧而言,采用这样的设计,可以针对不同类型的终端设备发送相同的DCI用于指示公共信息传输,可以降低网络设备发送公共信息的开销(公共信息的开销包括调度公共信息传输的DCI对应的资源开销,或者,公共信息的开销包括调度公共信息传输的DCI和公共信息传输对应的资源开销),进而节省网络设备侧功耗。
可选的,本申请实施例中,第一DCI的比特数与第二DCI的比特数相同,可以包括:
第一DCI包括的所有信息域的比特数总和与第二DCI包括的所有信息域的比特数总和相同。
或者,第一DCI的原始信息比特数与第二DCI的原始信息比特数相同,其中,本申请实施例中的原始信息比特数为DCI传输在执行CRC操作之前的比特数。原始信息比特数中可以包括零填充比特对应的比特个数,或者说,原始信息比特中可以包括零填充比特,零填充比特可以理解为为了使DCI比特数达到特定值而在DCI内添加的取值为0的比特。
或者,第一DCI在执行信道编码操作之前的比特数与第二DCI在执行信道编码操作之前的比特数相同。
或者,第一DCI对应传输的调制符号个数与第二DCI对应传输的调制符号个数相同。
或者,第一DCI对应传输的调制符号在解调之后对应的比特数与第二DCI对应传输的调制符号在解调之后对应的比特数相同。
需要说明的是,本申请实施例中,第一DCI包括的所有信息域的比特数总和与第二DCI包括的所有信息域的比特数总和相同,可以理解为,第一DCI包括的所有信息域对应的有效比特数总和与第二DCI包括的所有信息域对应的有效比特数总和相同;或者,第一DCI包括的所有信息域对应的有效比特数总和与第二DCI包括的所有信息域对应的有效比特数总和不相同,但是可以通过零比特填充(zero padding)或者截断(truncated)实现第一DCI包括的所有信息域的比特数总和与第二DCI包括的所有信息域的比特数总和相同。这里,有效的比特数可以理解为不是零填充比特的比特对应的比特数。例如第一DCI通过信息元素复用之后对应的比特数为S1个比特,第二DCI通过信息元素复用之后对应的比特数为S2个比特,其中S1不等于S2。假设S1小于S2,则通过增加零填充比特,可以调整第一DCI的比特数等于第二DCI的比特数,此时添加的零填充比特个数为S2-S1个;如果S1大于S2,则可以通过截断,调整第一DCI的比特数等于第二DCI的比特数,此时在第一DCI中丢弃的比特个数为S1-S2个。
可选的,本申请实施例中第一DCI中的第一标识可以通过第一DCI中包括的信息域显示或者隐式指示,显示或隐式指示实现方式可以参考上述指示第一DCI用于上行或下行数据传输调度的方式,在此不再赘述。
可选的,本申请实施例中,具有第一DCI格式的第一DCI包括的每个信息域的比特数均大小固定。
其中,具有第一DCI格式的第一DCI包括的每个信息域的比特数均大小固定,可 以理解为,具有第一DCI格式的第一DCI包括的所有信息域的信息比特数大小是固定的。其中,针对信息比特数大小固定的描述,可以参考上述第一DCI的比特数大小固定的第一点和第三点描述,在此不再赘述。

可选的,本申请实施例中,具有第二DCI格式的第一DCI包括的信息域中存在至少一个信息域的信息比特数大小是可配置的。
一种可能的实现方式中,第二DCI格式中包括的信息域可以从如下维度描述:
一方面,可选的,具有第二DCI格式的第一DCI包括具有第一DCI格式的第一DCI所包括的信息域中的一个或多个信息域。其中,当具有第一DCI格式的第一DCI与具有第二DCI格式的第一DCI中包括相同的信息域时,该信息域对应的信息比特数可以相同也可以不相同。例如,具有第一DCI格式的第一DCI与具有第二DCI格式的第一DCI中都包括上述第二信息域,在具有第一DCI格式的第一DCI中,第二信息域可以占用4比特,即最大可以指示16种不同的时间资源;在具有第二DCI格式的第一DCI中,第二信息域也可以对应4比特,或者可以根据RRC信令配置对应M比特,其中M为不同于4的整数。又例如,具有第一DCI格式的第一DCI中包括X1个比特用于指示MCS,具有第二DCI格式的第一DCI中可以通过X1-X2个比特用于指示MCS,而利用X2个比特实现RRC配置的其他功能,例如与触发非周期信道状态信息(channel state information,CSI)上报相关联的配置信息,本申请实施例对此不作具体限定。
另一方面,可选的,具有第二DCI格式的第一DCI中还包括具有第一DCI格式的第一DCI所不包括的信息域,例如可以包括如下至少一项信息域:
第十信息域,第十信息域用于指示多天线数据传输相关的控制信息,例如天线端口指示。
第十一信息域,第十一信息域用于指示码块组(code block group,CBG)相关的控制信息,例如码块组传输信息(code block group transmission information,CBGTI)、码块组清空指示信息(code block group flushing out information,CBGFI)。
第十二信息域,第十二信息域用于指示波束相关的控制信息,例如传输配置指示(transmission configuration indication,TCI)。
第十三信息域,第十三信息域用于指示载波相关的控制信息,例如下行分配索引(downlink assignment index,DAI)、上行/补充上行(supplementary uplink,SUL)指示。
第十四信息域,第十四信息域用于指示BWP切换的控制信息,例如网络设备为终端设备配置了4个BWP,第十四信息域可以通过2bit指示承载数据传输的BWP,这里的数据传输是通过包括第十四信息域的第一DCI调度实现的。这里的BWP切换可以理解为,网络设备与终端设备之间的数据传输从一个BWP切换到另外一个BWP上。
另一种可能的实现方式中,第二DCI格式中包括的信息域也可以从如下维度描述:
具有第二DCI格式的第一DCI中包括用于第一数据传输功能的信息域以及用于第二数据传输功能的信息域,其中,用于第一数据传输功能的信息域可以通过X比特实现,用于第二数据传输功能的信息域可以通过Y比特实现,X与Y之和不大于第一DCI的比特数大小。
本申请实施例中,第一数据传输功能指示用于数据传输调度的基本功能,第二数据传输功能指示用于数据传输调度的额外功能。
可选的,本申请实施例中,用于第一数据传输功能的信息域包括如下一项或多项信息域:
第一信息域、第二信息域、第三信息域、第四信息域或者第五信息域,其中,第一信息域至第五信息域的相关描述可参考上述实施例,在此不再赘述。
可选的,当第一DCI用于下行数据调度时,用于第一数据传输功能的信息域还包括如下一项或多项信息域:
第六信息域、第七信息域或者第八信息域,其中,第六信息域至第八信息域的相关描述可参考上述实施例,在此不再赘述。
可选的,当第一DCI用于上行数据调度时,用于第一数据传输功能的信息域还包括:
第九信息域,其中,第九信息域的相关描述可参考上述实施例,在此不再赘述。
可选的,本申请实施例中,用于第二数据传输功能的信息域包括如下一项或多项信息域:
第十信息域、第十一信息域、第十二信息域、第十三信息域或者第十四信息域,其中,第十信息域至第十四信息域的相关描述可参考上述实施例,在此不再赘述。
可选的,在本申请实施例中,具有第二DCI格式的第一DCI中可以包括非周期CSI触发指示信息,该信息用于指示终端设备上报非周期CSI测量结果。通过这种实现方式,网络设备可以根据数据传输需求,灵活指示终端设备是否上报非周期CSI测量结果,例如当网络设备与终端设备之间的数据传输信道状态变化比较快时,网络设备可以通过具有第二DCI格式的第一DCI中的信息域,指示终端设备上报非周期CSI测量结果,或者,当网络设备与终端设备之间的数据传输信道变化比较慢时,网络设备可以通过终端设备周期上报的CSI,确定与终端设备之间的数据传输信道质量,此时网络设备可以通过该信息域,指示终端设备不上报非周期CSI测量结果,或者可以通过区分第一DCI格式与第二DCI格式的指示域,指示终端设备不上报非周期CSI 测量结果,在这种情况下,默认具有第一DCI格式的第一DCI是不支持非周期CSI测量结果上报指示的,即具有第一DCI格式的第一DCI中不包括非周期CSI触发的指示信息。基于此,可以灵活地实现终端设备上报非周期CSI,保证数据传输效率。
可选的,本申请实施例中,第二数据传输功能的信息域是否生效可以通过具有第二DCI格式的第一DCI中的控制字段以位图(bitmap)或者二进制的方式指示,其中,生效的信息域对应的参数信息由RRC信令配置;或者,第二数据传输功能的信息域是否生效也可以直接通过RRC信令配置实现。
一种可能的实现方式中,可以通过具有第二DCI格式的第一DCI中的控制字段以位图的方式指示第二数据传输功能的信息域是否生效。例如,在具有第二DCI格式的第一DCI中,通过Y1个比特分别指示Y1种信息域,如果对应比特取值为1,表示该比特对应的信息域生效,或者说使能该比特对应的信息域。在使能该比特对应的信息域之后,该信息域对应的参数信息(如参数配置或者比特数大小)可以通过对应的RRC信令配置实现。例如通过2比特指示具有第二DCI格式的第一DCI中包括信息域1、信息域2,同时结合RRC信令配置信息域1、信息域2各自对应的参数信息。
另一种可能的实现方式中,可以通过具有第二DCI格式的第一DCI中的控制字段以二进制的方式指示第二数据传输功能的信息域是否生效。例如,Y个比特可以对应2 Y种不同的信息域,通过2 Y的具体取值可以确定使能的信息域,在使能相应的信息域后,该信息域对应的参数信息(如参数配置或者比特数大小)可以通过对应的RRC信令配置实现。例如Y=2,则Y个比特可以对应四个信息域,这Y个比特指示其中1个信息域生效时,例如指示多天线数据传输相关的控制信息生效时,终端设备可以再结合RRC信令配置确定多天线数据传输所对应的具体配置信息,例如DMRS端口个数,或者DMRS的端口传输类型(例如DMRS type 1或者DMRS type 2),或者DMRS传输在时间上占用的符号位置(例如DMRS mapping type A或者DMRS mapping type B),或者终端设备在进行多层传输时,每层传输与DMRS端口之间的映射关系。在本申请实施例中,用于指示信息域对应的参数具体信息的RRC信令可以通过具有第一DCI格式的第一DCI调度的PDSCH承载。
又一种可能的实现方式中,具有第二DCI格式的第一DCI中包括的多个信息域可以共用相同的比特,当使能其中一个信息域时,剩余的比特可以针对使能的信息域对应的参数信息做进一步指示。例如,具有第二DCI格式的第一DCI中包括4个比特,且第二数据传输功能占用4个比特且采用位图的形式指示使能的信息域,当只有1bit用于使能第二数据传输功能的一个信息域时,例如使能MIMO数据传输相关配置,则另外3bit可以用于指示最大8种不同MIMO数据传输相关配置。又例如,当只有2bit用于使能第二数据传输功能的两种不同的信息域时,例如使能MIMO数据传输相关配置与CBG数据传输相关配置,则另外2bit可以分别针对这两种功能各自对应的RRC配置进行进一步的细化指示,例如这2个bit分别对应MIMO数据传输相关配置与CBG数据传输相关配置,即通过2比特中的1个bit取值可以指示MIMO数据传输对应的两种不同配置,通过这2比特中的另外1个bit取值可以指示CBG数据传输对应的两种不同配置,或者,也可以通过2bit对MIMO数据传输相关配置与CBG数据传输相关配置的联合RRC配置进行指示,即这2个bit可以对应四种状态,每种状态都可以 指示MIMO数据传输相关配置和/或CBG数据传输相关配置。
在本申请实施例中,针对具有第二DCI格式的第一DCI,当信息域的具体配置参数通过RRC配置实现时,该RRC配置信令可以通过具有第一DCI格式的第一DCI所调度的PDSCH承载。由于具有第一DCI格式的第一DCI对应的信息域比特数是确定的,因此终端设备可以通过检测第一DCI格式,确定第一DCI所指示的调度信息,进而接收PDSCH获取RRC配置信令,终端设备在检测具有第一DCI格式的第一DCI时,也不存在RRC信令配置模糊的问题。
综上,由于本申请实施例中,具有第二DCI格式的第一DCI包括的信息域中存在至少一个信息域的信息比特数大小是可配置的,例如可以通过RRC信令配置,因此可以增加调度的灵活性。
示例性的,本申请实施例中,具有第一DCI格式的第一DCI例如可以对应现有的回退下行控制信息(fall back downlink control information,FB DCI);具有第二DCI格式的第一DCI例如可以对应现有的非回退下行控制信息(non fall back down control information,non-FB DCI),在此统一说明,以下不再赘述。
可选的,本申请实施例中,具有第一DCI格式的第一DCI和具有第二DCI格式的第一DCI可以对应相同的数据传输方向。例如,具有第一DCI格式的第一DCI和具有第二DCI格式的第一DCI都用于指示下行数据传输配置,或者都用于上行数据传输配置。
可选的,本申请实施例中,第一DCI可以对应不同类型的NR REDCAP终端设备。例如NR REDCAP终端设备有低端、中端、高端终端设备之分,上述第二数据传输功能可以针对不同类型的NR REDCAP终端设备而有所不同,本申请实施例对此不做具体限定。
可选的,本申请实施例中,用于承载第一DCI的控制信道例如可以是PDCCH、增强的PDCCH(enhanced PDCCH,EPDCCH)、MTC PDCCH(MPDCCH)、窄带PDCCH(narrowband PDCCH,NPDCCH)、或未来通信协议中新定义的作用与下行控制信道相同或相近的其他信道。对于控制信道的类型和名称,本申请实施例对此不做具体限定。

可选的,本申请实施例中,可以在图4所示的终端设备对应的USS和公共搜索空间(Common search space,CSS)内仅检测具有第一DCI比特数大小的DCI格式。或者说,在网络设备为终端设备配置的USS和CSS内,网络设备只为该终端设备配置具有第一DCI比特数大小的DCI格式,同上描述,这里的USS为网络设备为该终端设备配置的至少一个USS中的一个USS或者多个USS(包括全部配置的USS),CSS为网络设备为终端设备配置的至少一个CSS中一个CSS或者多个CSS(包括全部配置的CSS)。其中,如上所述,具有第一DCI比特数大小的DCI格式可以有一个也可以有多个,不同的DCI格式例如可以通过不同的RNTI来区分,或者也可以通过第一DCI中包括的控制字段指示。例如,其中两种DCI格式可以为上述的第一DCI格式和第二DCI格式。对于终端设备而言,当在被配置的所有USS和所有CSS内,仅配置具有第一DCI比特数大小的DCI格式时,该终端设备最多只需要检测1种DCI size的DCI格式,相比于现有技术中终端设备在CSS和USS内最多检测4种DCI size的DCI格式,采用本方案,可以降低终端设备检测DCI的复杂度,从而节省终端设备的功耗。
