Description

一种控制资源集合的获取方法、装置以及系统
本申请要求于2017年09月15日提交中国专利局、申请号为201710834225.0、申请名称为“一种控制资源集合的获取方法、装置以及系统”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
本发明涉及无线通信领域,尤其涉及无线通信系统中控制资源集合的配置。
背景技术
现有长期演进(Long Term Evolution,LTE)系统中,控制信道包括物理下行控制信道(Physical Downlink Control Channel,PDCCH)和增强下行物理控制信道(Enhanced Physical Downlink Control Channel,EPDCCH)两类。在时域上,PDCCH所在时频资源区域位于一个子帧的前0-3个正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号,EPDCCH所在时频资源区域为一个子帧内占除PDCCH以外的全部或部分下行OFDM符号;在频域上,PDCCH所在时频区域占用整个系统带宽,EPDCCH所在时频区域占用频域上至少一个物理资源块(Physical Resource Block,PRB)的频域宽度。
现有技术中,PDCCH所在时频资源的大小,通过物理控制格式指示信道(Physical Control Format Indicator Channel,PCFICH)信道中承载的指示信息和PBCH信道中承载的系统广播信息进行指示,在PCFICH信道中承载的指示信息包括2比特,仅用于指示PDCCH所在时频资源区域占用时域OFDM符号数量的大小,一般为0-3个OFDM符号;而PDCCH所在时频资源的频域大小通过物理广播信道(Physical Broadcast Channel,PBCH)中承载的系统广播信息进行间接指示,标准中预定义PDCCH区域的频域大小与系统带宽大小相等,因此可以利用PBCH信道中的承载的指示系统带宽大小的指示信息对PDCCH所在区域的频域大小进行间接指示。
对于EPDCCH所在频域资源的大小,通过高层信令进行指示(例如RRC信令),高层信令指示EPDCCH所在的子帧以及EPDCCH所占用的PRB的频域位置;其中PRB的位置可以为连续地占用一段频域资源,也可以离散地占用频域上非连续的多个PBR资源块。EPDCCH所在时域的子帧为标准预定义的子帧类型(例如,非多播信道的子帧,或某些无线帧配比内的非特殊子帧),而EPDCCH在时域所占的OFDM符号数量也需要根据接收到的PCFICH信道的指示信息进行调整。
在下一代无线通信系统中,例如:在新的无线(New Radio,NR)系统中,控制信道承载的下行控制信息用于指示数据信道所使用的资源块(Resource Block,RB)在数据区域的频域位置,数据信道用于承载下行数据。
为了提高终端设备盲检控制信道的效率,NR标准制定过程中提出了控制资源集合(control resource set,以下称为COREST)的概念。即,在控制区域为每个终端设备划分 一个或多个控制资源集合。网络设备可以在终端设备对应的任一控制资源集合上,向终端设备发送控制信道。此外,网络设备还需要通知终端设备所述控制资源集合的相关联的其他配置,例如搜索空间等。在控制区域上划分的多个控制资源集合中,每个控制资源集合的配置信息存在差异,例如频域宽度差异、时域长度差异等。此外,还存在可能影响当前控制资源集合的消息,例如主信息块(master information block,MIB)消息、时隙格式信息(Slot Format Information,简称SFI)等,从而导致控制资源集合或控制资源集合相关联的其他配置需要被重新配置。例如:突发的上行业务较多时,网络设备会利用SFI在时隙内配置较多的上行OFDM符号,而减少下行OFDM符号的数量。又如:根据所述服务小区业务的类型,网络设备改变下行数据的位置,若数据起始位置提前则会改变解调参考信号的位置。在这种前提下,网络设备如何能够及时高效地通知终端设备为其配置或重配置的一个或多个控制资源集合或控制资源集合相关联的其他配置,是一个亟待解决的技术问题。

本发明实施例中,“一个”意味着单个个体,并不代表只能是一个个体,不能应用于其他个体中。例如,本发明实施例中的“一个终端设备”指的是针对某一个终端设备,并不意味着只能应用于一个特定的终端设备。本申请中,术语“系统”可以和“网络”相互替换使用。“多个”是指两个或两个以上。“和/或”,描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
图1示出了本发明实施例中一种可能的应用场景示意图。该应用场景中的通信系统包括:网络设备,以及一个或者多个终端设备。其中,网络设备和终端设备可以通过一种或多种空口技术进行通信。
以下,对本发明实施例可能出现的术语进行解释。
通信系统:可以适用于LTE系统,或其他采用各种无线接入技术的无线通信系统,例如采用码分多址,频分多址,时分多址,正交频分多址,单载波频分多址等接入技术的系统。此外,还可以适用于使用LTE系统后续的演进系统,如第五代5G系统等。
网络设备:可以是基站,或者接入点,或者接入网设备,或者可以是指接入网中在空中接口上通过一个或多个扇区与无线终端通信的设备。网络设备可用于将收到的空中帧与IP分组进行相互转换,作为无线终端与接入网的其余部分之间的路由器,其中接入网的其余部分可包括网际协议(IP)网络。网络设备还可协调对空中接口的属性管理。例如,网络设备可以是全球移动通讯(Global System of Mobile communication,GSM)或码分多址(Code Division Multiple Access,CDMA)中的基站(Base Transceiver Station,BTS),也可以是宽带码分多址(Wideband Code Division Multiple Access,WCDMA)中的基站(NodeB,NB),还可以是长期演进(Long Term Evolution,LTE)中的演进型基站(Evolutional Node B,eNB或eNodeB),或者中继站或接入点,或者未来5G网络中的基站,例如gNB等,在此并不限定。需要说明的是,对于5G或NR系统,在一个NR基站下,可能存在一个或多个发送接收点(Transmission Reception Point,TRP),所有的TRP属于同一个小区,其中,每个TRP和终端都可以使用本申请实施例所述的测量上报方法。在另一种场景下,网络设备还可以分为控制单元(Control Unit,CU)和数据单元(Data Unit,DU),在一个CU下,可以存在多个DU,其中,每个DU和终端都可以使用本申请实施例所述的测量上报方法。CU-DU分离场景和多TRP场景的区别在于,TRP只是一个射频单元或一个天线设备,而DU中可以实现协议栈功能,例如DU中可以实现物理层功能。
终端设备:可以是无线终端也可以是有线终端,无线终端可以是指向用户提供语音和/或其他业务数据连通性的设备,具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网进行通信,无线终端可以是移动终端,如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机,例如,可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语言和/或数据。例如,个人通信业务(Personal Communication Service,PCS)电话、无绳电话、会话发起协议(Session Initiation Protocol,SIP)话机、无线本地环路(Wireless Local Loop,WLL)站、个人数字助理(Personal Digital Assistant,PDA)等设备。无线终端也可以称为系统、订户单元(Subscriber Unit)、订户站(Subscriber Station),移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、用户设备(User Device or User Equipment),在此不作限定。
符号(Symbol),包含但不限于正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号、稀疏码分多址技术(Sparse Code Multiplexing Access,SCMA)符号、过滤正交频分复用(Filtered Orthogonal Frequency Division Multiplexing,F-OFDM)符号、非正交多址接入(Non-Orthogonal Multiple Access,NOMA)符号,具体可以根据实际情况确定,在此不再赘述。
子帧(Subframe):一种时间单位,例如1毫秒(ms)。另外,一个子帧在时域上也可占用连续的K个符号,K为大于零的自然数。K的取值可以根据实际情况确定,在此并不限定。
时隙(Slot):一种时域资源的单位,在时域上包括连续的J个OFDM符号,J为大于零的自然数。一个时隙中包括的OFDM符号数量与循环前缀(CP,Cyclic prefix)有关。例如,对于正常CP(Normal cyclic prefix),一个时隙包括的OFDM符号数量为14;对于扩展CP(Extended cyclic prefix),一个时隙包括的OFDM符号数量为12。
资源块(Resource Block,RB):一种频域资源的单位,在频域上占用连续的M个子载波,M为大于零的自然数。例如,频域上占用连续的12个子载波。。
子载波宽度:频域上最小的粒度。例如,子载波带宽度的取值包括,15kHz,30kHz,60kHz,120kHz,240kHz,480kHz。
高层信令:区别于物理层信令,可以为如下消息中的一种或多种:主信息块(master information block,MIB)消息,系统信息,以及无线资源控制(radio resource control,RRC)消息。进一步的,系统信息可以是系统信息块(system information broadcast,SIB)消息,或者是用于配置随机接入信道(random access channel,RACH)资源的系统信息块消息。RRC消息可以是公共RRC消息,即发送给一个小区内的终端设备的RRC消息,或者可以是终端设备特定的RRC消息,即发送给特定终端设备的RRC消息。
资源单元组绑定(Resource Element Group Bundle,简称REG Bundle),由时域或频域连续的多个REG组成,且所述多个REG采用相同的预编码。例如,一个REG Bundle 可以包含2个、3个、6个或者其他数量的REG。这样,在一个REG bundle内包括的用于解调控制信道的参考信号的资源比单个REG中包括的参考信号的资源更多,可以提高信道估计的准确性,降低控制信道传输的误码率。
搜索空间:终端设备待检测的PDCCH(又称为候选PDCCH(PDCCH candidate))的集合或终端设备待检测的EPDCCH(又称为候选EPDCCH(EPDCCH candidate))的集合,并在所述集合上接收控制信息。一个搜索空间包括多个候选PDCCH或多个候选EPDCCH。后文中,将候选PDCCH和候选EPDCCH统称为候选控制信道。一个搜索空间包括的候选控制信道的聚合等级相同。搜索空间包括公共搜索空间(common search space,CSS)和用户设备特定搜索空间(UE Specific Search Space,UESS)两种类型。其中,CSS是小区内多个终端设备都要监听的搜索空间,USS是特定UE需要监听的搜索空间。另外,与所述候选控制信道相关的还涉及聚合等级以及下行控制信息(Downlink Control Information,简称DCI)格式。以PDCCH为例,终端设备需要在搜索空间(search space)检测PDCCH,进而获取PDCCH中承载的下行控制信息(DCI)。一个PDCCH是由L个连续的下行控制信道单元(control channel element,CCE)聚合而成,其中,L称为该PDCCH的聚合等级。聚合等级可以是大于或等于1的正整数。对于DCI格式,终端设备需要根据特定的DCI格式对应的比特大小进行信道译码,否则无法对接收到的控制信道的信号进行检测。

下面以5G通信系统为例阐述下行传输资源的配置情况。5G通信系统的NR标准中,下行传输资源在频域上占用全部或部分系统带宽,在时域上由若干个OFDM符号组成。控制信道可以由一个或多个控制信道单元(Control Channel Elements,CCE)组成。一个CCE由多个资源单元组(Resource Element Group,简称REG)组成,例如每个CCE包含6个REG。每个REG在频域上包括12个连续的子载波,在时域上包括1个OFDM符号。因此,网络设备发送控制信道时,需要在为每个终端设备分配的一个或多个控制资源集合上,将组成控制信道的一个或多个CCE映射到控制信道资源集合中的REG上,其中,REG为物理资源,CCE为组成控制信道的逻辑单元。CCE到REG的映射,即,把控制信道所使用的每个CCE映射到物理资源上。
目前,NR标准中,控制资源集合中包括的REG按照时域优先的方式进行编号,即,从控制资源集合包括的第一个OFDM符号且最低资源块编号的位置为起始进行编号。可选的,所述编号方式也可以根据控制资源集合的配置信息确定,即,可以按照频率优先的方式,或,时域优先的方式进行编号。
NR标准支持如下几种CCE到REG的资源映射方式:非交织式资源映射方式(non-Interleaved)、交织式资源映射方式(Interleaved)。在使用non-Interleaved进行CCE到REG的资源映射时,属于同一个CCE的REG在时域和或频域资源上是连续的。在使用Interleaved进行CCE到REG的资源映射时,属于同一个CCE的REG在时域和或频域上是离散映射的,且离散的粒度为REG绑定(REG bundle)的大小。其中,REG绑定由时域和或频域连续或相邻的多个REG构成,REG绑定的大小与控制资源集合的配置有关。例如,控制资源集合中CCE到REG的映射为交织,且控制资源集合在时域上包括1个或 2个OFDM符号时,REG绑定的大小可以为2或6;控制资源集合中CCE到REG的映射为交织式,且控制资源集合在时域上包括3个OFDM符号时,REG绑定的大小可以为3或6。当控制资源集合中CCE到REG的映射为非交织,则REG绑定的大小为6。
所述REG绑定大小给定的情况下,REG绑定包括的REG可以按照时域优先的方式组成,或者按照频域优先的方式组成。例如,REG绑定大小为2,若按照时域优先的方式,则组成REG绑定的REG由时域上连续的2个REG构成;若按照频域优先的方式,则组成REG绑定的REG由频域上连续的2个REG构成。可选的,REG绑定按照时域优先的方式还是按照频域优先的方式组成可以根据控制信道资源集合的配置来确定。或者,根据控制资源集合时域上OFDM符号的数量确定,例如,在控制资源集合包括2个或3个OFDM符号时,按照时域优先的方式组成REG绑定;在控制资源集合包括1个OFDM符号时,按照频优先的方式组成REG绑定
在所述非交织方式中,一个CCE包括的逻辑的REG绑定的编号与控制资源集合包括的物理的REG绑定的编号相同;在交织方式中,一个CCE包括的逻辑的REG绑定的编号对应至少一个与逻辑编号不同的物理的REG绑定的编号。例如,在非交织方式中,第j个CCE对应的物理的REG绑定的编号为{6j/L,6j/L+1,…,6j/L+L-1},其中,L为REG绑定包括的REG的个数。第i个REG绑定的编号对应的REG的编号为{i,iL+1,…,iL+L-1},其中,L的取值可以为{2,3,6}。此外,在交织方式中,第j个CCE对应的物理的REG绑定的编号为{f(6j/L),f(6j/L+1),…,f(6j/L+L-1)},其中,f(·)可表示为交织器。
图4出了本发明实施例中一种可能的下行传输资源上控制资源集合和数据信道所在的资源位置示意图。下行传输资源在频域上占用部分或全部下行系统带宽,在所示时隙中的第一个,第二个和第三个OFDM符号上,网络设备为其所服务的一个或多个终端设备配置了控制资源集合1(Control resource set 1)以及控制资源集合2(Control resource set 2),所述控制资源集合1和控制资源集合2在时域资源上重叠,在频域资源上独立。网络设备可以以时隙为单位进行数据传输的调度。具体的,在以时隙为单位进行数据调度时,终端设备在间隔固定周期时检测所述控制信道资源集合内的控制信道,所述周期的时间单位为一个时隙。所述周期可以通过用于配置控制信道资源集合的配置信息进行配置。
网络设备通过高层信令配置所述控制资源集合,所述高层信令包括广播信息、、系统信息(例如,初始接入时,包括用于配置初始接入信道(Random access channel)的系统信息)、RRC信令等,终端设备根据所述高层信令的配置获取控制资源集合。所述网络设备通过高层信令配置所述控制资源集合,包含配置以下至少一项:
控制资源集合所在的频域资源位置;
控制资源集合所在的时域的起始OFDM符号;
控制资源集合所在的时域上占用的长度,即控制资源集合在时域上包括的连续OFDM符号数;
控制资源集合中REG绑定(REG bundle)的大小;
控制资源集合的传输类型(transmission type),所述传输类型包括CCE到REG的资源映射时采用交织的方式,还是采用非交织的方式;
控制资源集合采用的资源映射方式,所述资源映射方式包括频域优先(Frequency-First, 简称F-F)资源映射方式或者时域优先(Time-First,简称T-F)资源映射方式。
其中:
上述控制资源集合所在的频域资源位置可以通过频域带宽、频域上的REG个数、频域上的RE个数等方式指示;上述时域的起始OFDM符号可以通过一个时隙上的OFDM符号的索引或者编号,或者使用一个或多个比特值指示一个时隙中的时域位置等指示;上述时域上占用的长度可以为OFDM符号的个数;上述REG绑定的类型可以是一个REG绑定在时域和频域上分别包含的REG个数,例如[2*3],表示在一个REG绑定中时域上包括连续的2个REG,频域上包括连续的3个REG。在一个REG绑定中,所有的REG采用相同的预编码方式;
上述传输类型为按照REG绑定为粒度,将承载有控制信息的CCE映射到物理资源的方式,其中,所述传输方式包括交织方式和非交织方式。在非交织方式中,一个CCE包括的逻辑的REG绑定的编号与控制资源集合包括的物理的REG绑定的编号相同;在交织方式中,一个CCE包括的逻辑的REG绑定的编号对应一个与逻辑编号不同的物理的REG绑定的编号。例如,在非交织方式中,第j个CCE对应的物理的REG绑定的编号为{6j/L,6j/L+1,…,6j/L+L-1},其中,L为REG绑定包括的REG的个数。第i个REG绑定的编号对应的REG的编号为{i,iL+1,…,iL+L-1},其中,L的取值可以为{2,3,6}。此外,在交织方式中,第j个CCE对应的物理的REG绑定的编号为{f(6j/L),f(6j/L+1),…,f(6j/L+L-1)},其中,f(·)可表示为交织器。
上述控制资源集合采用F-F资源映射方式或者T-F资源映射方式可以通过代表相应映射方式的比特值、索引或者编号等能够使得终端设备确定所述控制资源集合的资源映射方式的任意一种指示方式来指示,或者还可以默认所述控制资源集合的资源映射方式为上述F-F资源映射方式或T-F资源映射方式中的一种,这种默认的资源映射方式可以是在标准或协议中规定的,也可以是网络设备和终端设备提前协商的,又或者是网络设备预先通知或配置给终端设备的;具体的,在使用F-F资源映射方式进行CCE到REG的资源映射时,属于同一个CCE的REG在下行传输资源上的映射顺序是先频域映射后时域映射。在使用T-F资源映射方式进行CCE到REG的资源映射时,属于同一个CCE的REG在下行传输资源上的映射顺序是先时域映射后频域映射。
图5示出了本发明实施例中一种可能的用于解调的参考信号的位置示意图。NR标准中还通过了用于解调的参考信号(例如DMRS)的时域符号位置,所述用于解调的参考信号可以位于每个时隙的第3个符号(编号为2的符号)或第4个符号(编号为3的符号)。当所述用于解调的参考信号位于第3个符号时,终端设备的控制资源集合在时域上最多占用2个符号(第1个和/或第2个符号),当所述用于解调的参考信号位于第4个符号时,终端设备的控制资源集合在时域上最多占用3个符号(第1个、第2个和/或第3个符号)。在用于解调的参考信号位置变化前,网络设备已经为所服务的一个或多个终端设备配置了用于检测控制信道的控制资源集合,而所述控制资源集合可能会受到影响,进而网络设备无法在已经配置的一个或多个控制资源集合上发送控制信息,导致终端设备无法在相应的控制资源集合上接收到有效的控制信息,则网络设备需要通过高层信令对所述一个或多个终端设备所对应的一个或多个控制资源集合进行重配置。终端设备的接入会产生时延,并 且高层信令的重配置也会带来信令的额外开销。因此,如何在尽量低的信令开销的基础上,高效地获取终端设备对应的一个或多个控制资源集合,是亟待解决的技术问题。
下面将基于上面所述的本发明涉及的共性方面,对本发明实施例1和2进一步详细说明。在实施例的阐述中,忽略上下行可能存在的时延,假设网络设备的发送时刻与终端设备的接收时刻相同。对于网络设备的发送和终端设备的接收相对应的处理,实施例中多从终端设备侧角度阐述,本领域技术人员可以理解,终端设备从网络设备接收,意味着网络设备进行了发送。需要说明的是,本发明实施例1和2中所涉及的“第一控制资源集合”、“第二控制资源集合”、“第三控制资源集合”、“第四控制资源集合”、第五控制资源集合”以及“第六控制资源集合”的表述所代表的集合数量可以为一个或者多个,根据通信系统的实际情况、标准或协议的规定、和/或网络设备的配置等其他可能影响控制资源集合配置的场景,所述每种集合的数量可以为任意数量。本发明中还涉及“资源大小”的表述,本领域技术人员可以理解,所述资源大小可以通过资源单元组的数量、资源单元的数量、控制信道单元的数量或者物理资源块的数量等来表示,能够提供资源大小上的比对即可,本发明实施例中不做具体限定。
另外,本发明实施1中各个步骤的编号不限定具体执行过程中的先后顺序,在不同的可选设计中,上述各个步骤执行先后顺序会进行适应性的调整。

关于步骤601:
一种可选的设计中,所述至少一个指示信息可以包含一个或者多个第二指示信息,所述一个或多个第二指示信息包含或指示时域资源位置,不同的第二指示信息所包含或指示的时域资源位置上所承载的信息类型可以不同。具体的,所述终端设备可以根据所述至少一个第二指示信息中的一个第二指示信息或所述至少一个第二指示信息的组合确定步骤601中的所述第一时域资源位置。
可选的,所述第二指示信息可以为一个用于指示用于解调的参考信号(DMRS)的时域资源位置的指示信息(为阐述方便,下文中这种指示信息称为第一类型指示信息)。例如,所述指示信息指示所述DMRS在一个时隙中的符号位置,可以为第3个符号(若时隙首符号从0开始编号,则为编号为2的符号)或者第4个符号(若时隙首符号从0开始编号,则为编号为3的符号)。所述第一类型指示信息可以承载于广播消息、剩余最小系统信息RMSI等多种类型的消息或信息中。
一种实现中,控制信息在一个时隙中的控制资源集合1中传输,所述控制资源集合1包含了所述时隙中的第3个符号;若DMRS需要占用第3个符号,则所述网络设备需要调整所述控制信息的传输,在新的控制资源集合2上发送所述控制信息。在该实现中,所述终端设备需要根据所述指示信息,获取所述新的控制资源集合。
可选的,所述至少一个第二指示信息为一个指示时隙格式的指示信息(为阐述方便,下文中这种指示信息称为第二类型指示信息),通过该指示信息,终端设备可以确定下行符号在所述时隙中的位置。在周期或非周期性控制信息传输的场景下,用于控制信息传输的每个时隙格式信息可能不同,某些情况下,控制信息传输所在的符号位置可能会受到影响。所述指示信息可以包含时隙格式信息本身,或者时隙格式信息的索引或编号,所述第二类型指示信息可以承载于一下行信息中,例如下行控制信息(Downlink Control Information,简称DCI)。具体的,所述时隙格式信息用于指示在一个时隙中下行符号个数、未知类型符号(Unknown)个数以及上行符号的符号个数,或者用于指示一个时隙中下行符号、位置类型符号以及上行符号的符号个数配比。
一种实现中,所述网络设备根据预先配置的规则确定所述时隙格式,所述预先配置的规则可以是标准或协议规定的,也可以是网络设备根据不同的传输场景或传输需要确定的,并已经提前通知或发送给所述终端设备;
又一种实现中,所述网络设备根据预先设置的多种时隙格式信息确定所述时隙格式;例如,所述多种时隙格式信息可以通过表格的形式体现,或者其他形式,这里不做具体限定。以表格的格式体现所述多种时隙格式信息可以参考下表1。这里需要说明的是,表1所展示的格式、参数以及参数的数值仅是一种可选的方式,不构成对实际表格内容和格式的限定。可选的,所述指示信息可以包含格式索引;当所述格式索引包含在所述指示信息中时,所述终端设备可以根据所述格式索引确定一个时隙中的下行符号可能的位置。

可选的,所述至少一个第二指示信息中包含上述第一类型指示信息和上述第二类型指示信息。在这种情况下,所述第一类型指示信息用于指示DMRS的时域资源位置,即用于指示被占用的、无法用于控制信息传输的时域资源位置,所述第二类型指示信息用于指示时隙格式,即用于指示所述时隙中哪些符号用于下行传输。所述第一类型指示信息和所述第二类型指示信息可以承载于相同或不同类型的下行信息或下行消息中,这里不做具体限定。
需要说明的是,所述第二指示信息还可以是其它类型的、用于指示对于控制信息传输可用或不可用的时域资源位置的指示信息,上述的第一类型和第二类型指示信息仅仅是列举说明,不作为对第二指示信息类型的限定。在存在多种类型的第二指示信息的情况下,所述终端设备可以根据所述多个第二指示信息中的一个或多个确定步骤601中的所述第一时域资源位置。
在该种可选的设计中,进一步地,所述至少一个指示信息还包括用于指示第三控制资源集合的至少一个第一指示信息。
可选的,所述终端设备可以在获取所述第二控制资源集合的过程中,确定所述第三控制资源集合是否可以作为第二控制资源集合,或者包含在所述第二控制资源集合中。下文中将进行示例性的说明。
可选的,在所述至少一个指示信息包括用于指示所述第三控制资源集合的至少一个第一指示信息和用于指示所述第一时域资源位置的至少一个第二指示信息的前提下:
若所述至少一个第一指示信息在所述至少一个第二指示信息之前发送(不考虑时延或其他可能造成收发时刻存在较大误差的特殊情况,所述终端设备在接收所述至少一个第二指示信息之前接收到所述至少一个第一指示信息),可选的,在接收到所述至少一个第二指示信息之前,所述第三控制资源集合为不用于接收控制信息的候选控制资源集合,即所述第三控制资源集合是所述网络设备预先配置给所述终端设备备用的候选控制资源集合。在未收到所述至少一个第一指示信息的触发之前,所述终端设备不在所述第三控制资源集合上接收控制信息。
若所述至少一个第一指示信息与所述至少一个第二指示信息同时发送(所述终端设备同时接收到所述至少一个第一指示信息与所述至少一个第二指示信息),所述至少一个指示信息可以承载在同一个高层信令,例如广播消息中,或者所述至少一个第一指示信息和所述至少一个第二指示信息分别承载在不同类型的消息或信息中。这里不做具体限定,所述消息或信息的类型可以视指示内容不同而不同。
又一种可选的设计中,所述网络设备确定至少一个指示信息和传输控制信息的时域资源位置,具体包括:
所述网络设备根据步骤100中的为所述终端设备配置的可用的控制资源集合,确定所述可用的控制资源集合包括第一控制资源集合,所述第一控制资源集合的部分或全部占用步骤101中所述第一时域资源位置。
可选的,所述网络设备根据所述至少一个指示信息确定可用于和/或不可用于控制信息传输的时域资源位置,例如,DMRS所占用的时域资源位置,和/或时隙格式信息所确定的下行符号的位置和/或个数等时域资源位置,和/或其它原因导致对于控制信息传输可用或不可用的时域资源位置,确定所述第一控制资源集合;
例如,当DMRS的位置改变时,可能导致所述第一控制资源集合中的部分或全部第一控制资源集合中符号位置被DMRS占用,无法用于传输控制信息;
又如,当时隙格式改变时,下行符号数量发生改变,可能导致所述第一控制资源集合中部分或全部第一控制资源集合的符号位置用于上行符号或者未知类型的信息传输,无 法用于传输下行控制信息;
进一步,所述网络设备判断所述第一控制资源集合中的部分或全部占用部分或全部所述第一时域资源位置,则所述网络设备确定第二控制资源集合,并生成所述至少一个指示信息,并将所述至少一个指示信息发送给所述终端设备。
关于步骤603:
针对“根据所述至少一个指示信息,获取第二控制资源集合“的方式,本发明实施例1中提供多种可选的设计,在下述多种可选的设计中,所述第二控制资源集合中不包含所述第一时域资源位置上的时域资源,以避免终端设备在不可用于控制信息传输的时域资源上检测而降低终端设备的检测效率和造成不必要的功耗。
这里需要说明的是所述终端设备根据所述至少一个指示信息获取第二控制资源集合的方式与所述网络设备确定所述第二控制资源集合的方式相同,保证所述终端设备和网络设备在相同的第二控制资源集合上执行各自的处理。这种获取方式或确定方式是网络设备和终端设备预先约定好的,或者网络设备预先通知所述终端设备的,还可以是协议或标准规定的,这里不做具体限定。同样的说明适用于本发明实施例2。需要说明的是,下文各种可选的设计仅作为示例性的说明,不对具体的实现方式进行限定。
一种可选的设计中,所述终端设备根据所述第一时域资源位置和所述第一控制资源集合,获取所述第二控制资源集合。
可选的,所述第二控制资源集合为所述第一控制资源集合中未占用所述第一时域资源位置的部分。
具体的,若所述第一控制资源集合的部分占用所述第一时域资源位置,则所述第二控制资源集合为所述第一控制资源集合中剩余的未占用所述第一时域资源位置的部分,即所述第二控制资源集合为所述第一控制资源集合的真子集。这样的实现方式,使得所述第二控制资源集合可以避开不可用的时域资源位置,并且不影响所述时隙中除所述第一控制资源集合占用的时域资源以外的其他时域符号上的信息传输。
例如,所述第一控制资源集合占用一个时隙中的第2个符号和第3个符号,若时隙格式信息和/或用于解调的参考信号等至少一个指示信息指示所述第3个符号不能用于控制信息传输,则所述第二控制资源集合的时域资源位置可以确定为所述时隙中的第2个符号。
可选的,所述第二控制资源集合在时域资源上的起始位置比所述第一控制资源集合提前第一时长。
一种实现中,所述第二控制资源集合与所述第一控制资源集合占用相同的频域资源大小和时域资源大小,这种实现方式,可以保证所述第二控制资源集合和第一控制资源集合占用相同的时域资源大小以及相同的频域资源大小,减少由于控制资源集合的时域资源位置变化带来的额外信令开销以及接入延时。
具体的,在满足所述第二控制资源集合中不包含所述第一时域资源位置上的时域资源的前提下,所述第二控制资源集合与所述第一控制资源集合占用相同的频域资源大小和时域资源大小,则所述第二控制资源集合与所述第一控制资源集合在时域资源的起始位置上有第一时长的偏移,所述第一时长的长度需要根据所述第一时域资源位置与所述第一控制 资源集合的时域资源位置确定。
例如,第一控制资源集合的时域资源位置为一个时隙中的第2个和第3个符号,若时隙格式信息和/或用于解调的参考信号等至少一个指示信息指示所述第3个符号不能用于控制信息传输,则所述第二控制资源集合的时域资源位置可以确定为所述时隙中的第1个和第2个符号,所述第一时长为1个符号,偏移方向为提前,以保证所述第二控制资源集合和第一控制资源集合占用相同的时域资源大小,进而占用相同的频域资源大小,不影响控制信息的传输。在这种实现方式中,若第1个符号已经被预先配置作为其他用途或者为其他终端设备使用,则需要采用冲突解决机制来处理所述第二控制资源集合的获取而对所述其他用途或者其他终端设备造成的影响,本发明实施例1中不对这种冲突解决机制具体阐述,可以采用现有技术中类似的冲突解决机制,例如优先级设置等方式,或者其它可能采用的冲突解决机制进行处理,以在最大程度上保证不影响控制信息的传输,又降低对所述预先配置的其他用途或者其他终端的影响。
又如,第一控制资源集合的时域资源位置为一个时隙中的第3个符号,若时隙格式信息和/或用于解调的参考信号等至少一个指示信息指示所述第3个符号以及所述时隙中的第2个符号均不能用于控制信息传输,则所述第二控制资源集合的时域资源位置可以确定为所述时隙中的第1个符号,所述第一时长为2个符号,偏移方向为提前,以保证所述第二控制资源集合和第一控制资源集合占用相同的时域资源大小,进而占用相同的频域资源大小,不影响控制信息的传输。类似的,可以采用上文中提到的冲突解决机制处理可能存在的冲突,这里不再赘述。
又一种实现中,所述第二控制资源的时域资源大小小于所述第一控制资源集合的时域资源大小;由于所述第二控制资源集合在时域资源的起始位置比第一控制资源集合提前第一时长,可能导致可用于所述第二控制资源集合的时域资源小于所述第一控制资源的时域资源大小。
例如,第一控制资源集合的时域资源位置为一个时隙中的第2个和第3个符号,若时隙格式信息和/或用于解调的参考信号等至少一个指示信息指示所述第3个符号和所述时隙中的第1个符号不能用于控制信息传输,则所述第二控制资源集合的时域资源位置可以确定为所述时隙中的第2个符号,所述第一时长为1个符号,偏移方向为提前,偏移后的时域资源小于第一控制资源集合的时域资源。
在该可选的设计中,进一步可选的,所述至少一个指示信息还用于指示第三控制资源集合,例如所述至少一个指示信息包含用于指示所述第三控制资源集合的至少一个第一指示信息。在根据所述第一时域资源位置和所述第一控制资源集合获取所述第二控制资源集合的前提下,所述终端设备可以不使用所述第三控制资源集合。
例如,所述网络设备通过高层信令指示了所述至少一个第一指示信息和所述至少一个第二指示信息,若通过所述第二指示信息和所述第一控制资源集合,可以在第二控制资源集合中获取足够的资源用于控制信息传输,则所述终端设备不在所述第三控制资源集合上接收控制信息。以CSS和USS为例,进一步阐述如下。
所述第三控制资源集合中包括公共搜索空间,所述公共搜索空间(CSS)用于传输服务小区的公共控制信息。由于服务小区内所有终端设备均可检测到所述公共搜索空间内的控制信道,因此第三控制资源集合的频域的最大宽度应配置在一定阈值以内,以实现具有 最小接入带宽能力的终端设备可以接入到系统。另外,公共搜索空间中包括的候选控制信道的聚合等级会更大,即,一个候选控制信道在第三控制资源集合内占用的资源更多,可能没有足够的剩余资源承载额外的候选控制信道。因此,当终端设备可以获取至少一个可用的第二控制资源集合时,则不会在所述第三控制资源集合内检测用户特定搜索空间(USS)包括的候选控制信道。
又一种可选的设计中,所述终端设备将所述至少一个指示信息中的至少一个第一指示信息指示的所述第三控制资源集合作为所述第二控制资源集合。
一种实现中,所述终端设备直接将所述至少一个指示信息指示的所述第三控制资源集合作为所述第二控制资源集合。在这种实现中,在至少一个指示信息中指示了第三控制资源集合的情况下,所述终端设备不考虑所述至少一个指示信息所指示的所述第一时域资源位置与所述第一控制资源集合中时域资源位置的重叠情况,直接获取所述第三控制资源集合作为所述第二控制资源集合。这样,提高了控制资源集合的获取效率,降低了控制信息的检测时延。
又一种实现中,当所述终端设备被配置的可用的控制资源集合仅包括所述第一控制资源集合时,将所述至少一个指示信息指示的所述第三控制资源集合作为所述第二控制资源集合。
具体的,所述可用的控制资源集合仅包括部分或全部占用所述第一时域资源位置的第一控制资源集合时,所述终端设备直接获取所述第三控制资源集合作为所述第二控制资源集合。这样,提高了控制资源集合的获取效率,降低了控制信息的检测时延。
再一种实现中,当所述终端设备被配置的可用的控制资源集合仅包括所述第一控制资源集合且所述第一控制资源集合的全部占用所述第一时域资源位置时,将所述至少一个指示信息指示的所述第三控制资源集合作为所述第二控制资源集合。
具体的,所述可用的控制资源集合仅包括全部占用所述第一时域资源位置的第一控制资源集合时,所述终端设备直接获取所述第三控制资源集合作为所述第二控制资源集合。这样,提高了控制资源集合的获取效率,降低了控制信息的检测时延。
在该可选的设计中,仅列举了几种在所述至少一个指示信息指示了所述第三控制资源集合的前提下,所述终端设备将所述第三控制资源集合作为所述第二控制资源集合的实现。这样的设计是在网络设备牺牲一定的信令损耗而为所述终端设备配置了所述第三控制资源集合的前提下,提高所述终端设备对控制信息的检测效率而提供的选择。
再一种可选的设计中,在所述可用的控制资源集合包含所述第四控制资源集合的前提下,所述第二控制资源集合为所述第四控制资源集合。
这里需要说明的是,若所述可用的控制资源集合还包括未占用所述第一时域资源位置的所述第四控制资源集合,则所述终端设备获取第二控制资源集合为:所述终端设备获取所述第四控制资源集合。这里的获取可以是终端设备直接获取第四控制资源集合进行后续控制信息的接收,无需额外再执行将所述第四控制资源集合作为所述第二控制资源集合,两个集合的区分只是为了阐述方案方便,不隐含是否有多余的执行动作。
对于步骤604:
一种可选的设计中,所述终端设备在所述第二控制资源集合上接收所述控制信息为:所述终端设备仅在所述第二控制资源集合上接收所述控制信息。
又一种可选的设计中,在所述可用的控制资源集合还包括第四控制资源集合,所述第四控制资源集合用于发送所述控制信息,所述第四控制资源集合未占用所述第一时域资源位置的前提下,所述终端设备在所述第二控制资源集合上接收所述控制信息包括:所述终端设备在所述第二控制资源集合和所述第四控制资源集合上接收所述控制信息。
在该可选的设计中,所述终端设备在接收所述至少一个指示信息之前获取的可用的控制资源集合中,若存在不与所述第一时域资源位置部分或全部重叠的第四控制资源集合,则所述网络设备仍然在所述第四控制资源集合上传输控制信息,则终端设备仍然需要在所述第四控制资源集合上接收控制信息,这样可以沿用之前的可用资源,提高资源利用效率。
本发明实施例1中,所述方法还包括以下步骤中的至少一个:
步骤605:所述终端设备确定所述第二控制资源集合的资源单元组绑定(REG Bundle)的映射方式,所述映射方式为频域优先映射或时域优先映射;
步骤606:所述终端设备确定所述第二控制资源集合的资源单元组绑定(REG Bundle)中资源单元组的数量。
这里需要说明的是,上述步骤605和/或步骤606中终端设备可以根据预先配置的规则进行相应的确定,或者根据网络设备下发的配置信息确定;若根据所述预先配置的规则进行处理,则所述预先配置的规则可以是标准或协议规定的,也可以是网络设备根据不同的传输场景或传输需要确定的,并已经提前通知或发送给所述终端设备,所述终端设备能够根据第二控制资源集合确定步骤605中的REG Bundle映射方式和/或步骤106中的REG Bundle中REG的数量。
对于步骤605:
一种可选的设计中,若所述第一控制资源集合的时域资源的符号数大于或等于所述第二控制资源集合的时域资源的符号数,且所述第二控制资源集合的时域符号数不等于1,则所述终端设备确定:
可选的,所述第二控制资源集合与所述第一控制资源集合的资源单元组绑定(REG Bundle)的映射方式相同;这种方式下,在所述第二控制资源集合的时域符号数大于1的情况下,尽量保持所述第二控制资源集合与所述第一控制资源集合使用相同的REG Bundle映射方式,以提高终端设备的检测效率。
例如,第一控制资源集合占用一个时隙中的前3个符号,并且REG Bundle映射方式采用时域优先映射方式;在所述第一时域资源位置指示所述前3个符号中的第3个符号对于控制信息传输不可用的前提下,则所述终端设备根据本发明实施例1上文中所阐述的内容确定第二控制资源集合占用所述时隙中的前2个符号,并进而确定第二控制资源集合的REG Bundle映射方式仍然可以采用与第一控制资源集合相同的时域优先映射方式。可选的,所述终端设备也可以确定在时域资源变小的前提下,进而确定第二控制资源集合的REG Bundle映射方式采用频域优先映射方式。
可选的,所述终端设备确定所述第二控制资源集合的REG Bundle的映射方式为频域优先映射;这种方式下,可以尽量保证REG Bundle优先在频域上映射,在所述第二控制资源集合的时域符号数较小的情况下优化REG Bundle的设置,便于终端设备进行控制信息接收。
又一种可选的设计中,若所述第二控制资源集合的时域资源的符号数等于1,则所述终端设备确定所述第二控制资源集合的资源单元组绑定(REG Bundle)的映射方式为频域优先映射。
再一种可选的设计中,所述终端设备可以根据网络设备下发的用于配置REG Bundle映射方式的配置信息,确定所述第二控制资源集合的REG Bundle的映射方式。
可选的,所述配置信息可以以高层信令或者物理层信令的方式下发,可以由网络设备在所述至少一个指示信息之前预先通知或发送给终端设备,也可以在所述至少一个指示信息的同时或者之后发送给终端设备,这里不做具体限定,以网络设备针对此设计进行的预先通知或配置,或者网络设备和终端设备协商的结果,又或者标准或协议的规定来确定。
对于步骤606:
一种可选的设计中,若所述第二控制资源集合包含的资源大小小于第一阈值,或者,所述第二控制资源集合无法支持第一控制资源集合所支持的部分或全部聚合等级,则所述终端设备确定所述第二控制资源集合中资源单元组绑定(REG Bundle)中的资源单元组的数量小于所述第一控制资源集合中REG Bundle中的REG的数量。这种设计,使得在控制资源集合的资源大小变小的情况下,减少REG Bundle中REG的数量,优化了REG Bundle的设置。
例如,第一控制资源集合占用一个时隙中的前3个符号,并且REG Bundle包含6个REG;在所述第一时域资源位置指示所述前3个符号中的第3个符号对于控制信息传输不可用的前提下,则所述终端设备根据本发明实施例1上文中所阐述的内容确定第二控制资源集合占用所述时隙中的前2个符号,资源数量小于第一阈值,或者无法支持第一控制资源集合所支持的聚合等级8,则所述终端设备确定第二控制资源集合的REG Bundle大小为3。若第二控制资源集合的资源大小大于第一阈值或者可以支持第一控制资源集合所支持的全部或部分聚合等级,所述终端设备可以确定第二控制资源集合的REG Bundle包含6个REG。
又一种可选的设计中,所述终端设备根据第一配置信息确定所述第二控制资源集合的资源单元组绑定(REG Bundle)中资源单元组的数量。
这里需要说明的是,在确定步骤105中REG Bundle映射方式时,可以结合步骤106中REG Bundle中REG的数量的确定方式,或者,在确定步骤106中REG Bundle中REG的数量时,可以结合步骤105中REG Bundle映射方式的确定方式,综合考虑以确定第二控制资源集合的REG Bundle映射方式以及REG Bundle中REG数量。这里不做具体限定。
由于控制资源集合的改变,进一步导致REG Bundle映射方式和/或REG Bundle中REG数量的改变,可能会影响搜索空间的配置。因此,本发明实施例1中的所述方法还包括以下步骤:
步骤607:所述终端设备确定所述第二控制资源集合的搜索空间配置信息,所述搜索空间配置信息包含候选控制信道数量、聚合等级以及下行控制信息格式中的一个或多个。
一种可选的设计中,所述终端设备确定所述第二控制资源集合的搜索空间配置信息,包括:
一种实现中,所述终端设备根据所述第二控制资源集合包含的资源大小以及所述第一控制资源集合的搜索空间配置信息中的至少一个,确定所述第二控制资源集合的搜索空间配置信息;
可选的,若所述终端设备确定所述第二控制资源集合包含的资源大小小于第二阈值,则确定所述第二控制资源集合的搜索空间的配置信息与所述第一控制资源集合的第一搜索空间配置信息相同,或者确定所述第二控制资源集合的搜索空间的配置信息为第二搜索空间配置信息,所述第二搜索空间配置信息是所述终端设备从所述网络设备接收的,或者根据预先设置的规则确定的,这里关于配置信息和预先设置的规则的解释参见上文中类似表述部分的阐述。
可选的,若所述终端设备确定所述第二控制资源集合包含的资源大小不小于第二阈值,则确定所述第二控制资源集合的搜索空间的配置信息与所述第一控制资源集合的第一搜索空间配置信息相同,或者确定所述第二控制资源集合的搜索空间的配置信息为第二搜索空间配置信息,所述第二搜索空间配置信息是所述终端设备从所述网络设备接收的,或者根据预先设置的规则确定的。
例如,第二控制资源集合包含的资源大小相对于第一控制资源集合的搜索空间中聚合等级大小而言足够多时,所述第二控制资源集合的搜索空间中聚合等级大小不变。举例说明,控制资源集合从32个CCE变化为16个CCE时,虽然资源减少,但依然可以支持聚合等级为8的候选控制信道。此时,搜索空间包括的聚合等级不变。可选的,若第二控制资源集合的资源减少到无法支持第一控制资源集合所支持的聚合等级8,则第二控制资源集合的搜索空间中聚合等级集合中需要去掉数量为8的项。
又如,第一控制资源集合的搜索空间中候选控制信道分布于一个时隙的前3个符号中,若候选控制信道的数目为16,而这16个候选控制信道中的4个位于所述时隙中的第3个符号;经由所述至少一个指示信息的指示,终端设备确定所述第3个符号对于控制信息传输不可用,则所述终端设备确定第二控制资源集合的候选控制信道的数量为12。
再如,若第二控制资源集合包含的资源大小相对于第一控制资源集合的搜索空间中控制信息格式的大小足够,且第二控制资源集合中传输的控制信息的编码码率不大于1,则仍可以使用第一控制资源集合的搜索空间中的控制信息格式。
再如,若用于第一控制资源集合中候选控制信道接收的下行控制信息DCI的格式大小为{40bits,60bits,120bits};其中,120bits对应了聚合等级为8和16的候选控制信道。若由于第二控制资源集合的资源大小无法支持聚合等级8和16,导致聚合等级为8和16的候选控制信道不包括在控制资源集合内时,则对应的DCI格式也无需进行检测。进而所述终端设备确定所述DCI格式的大小从{40bits,60bits,120bits}变为了{40bits,60bits}。
针对上述步骤606和607中所提到的配置信息,这里需要说明的是,所述配置信息可以由网络设备通过高层信令或者物理层信令的方式下发,由网络设备在所述至少一个指示信息之前预先通知或下发给终端设备,也可以在所述至少一个指示信息的同时或者之后下发给终端设备,这里不做具体限定,以网络设备针对该些步骤进行的预先通知或配置,或者网络设备和终端设备协商的结果,又或者标准或协议的规定来确定。
实施例2
下面对本发明实施例2进一步详细说明。
本发明的实施例2提供一种控制资源集合的获取方法,如下根据图7对本发明实施例2中控制资源集合的获取方法的一种具体实现方式进行说明。这里需要说明的是,本发明实施例2与本发明实施例1所应用的场景相同,区别在于实施例2中控制资源集合的时频位置不受其时域上的资源位置改变为对于控制信息传输不可用的影响。即使网络设备确定了如本发明实施例1中的第一时域资源位置以及至少一个指示信息,依然在第一控制资源集合上传输控制信息。对于终端设备来说,按照预先的通知、约定或者规定,依然在第一控制资源集合上接收控制信息。为了更清楚的阐述本发明实施例2的技术方案,由于不涉及第一控制资源集合的时域位置改变,以下将第一和第二控制资源集合统一称为第五控制资源集合。
步骤701:网络设备为终端设备配置可用的第五控制资源集合;
步骤702:所述网络设备向终端设备发送至少一个指示信息,所述至少一个指示信息用于指示第一时域资源位置,所述第一时域资源位置对于控制信息传输不可用;
在步骤702中,所述网络设备确定至少一个配置信息,所述至少一个配置信息包括第一时域资源位置,所述第一时域资源位置对于控制信息传输不可用,所述至少一个指示信息用于指示所述至少一个配置信息。
步骤703:所述终端设备从所述网络设备接收所述至少一个指示信息。
步骤704:所述终端设备根据所述至少一个指示信息,在所述可用的第五控制资源集合上接收控制信息。
需要说明的是,本发明实施例2中涉及与实施例1中一些相同或相似技术术语和技术特征以及交互方式(例如接收或发送配置信息、指示信息的方式等)的解释参见本发明实施例1中的阐述,这里不再赘述。
通过上述步骤701-704所实现的控制集合的获取方法,不论所述第五控制资源集合是否包含所述第一时域资源位置中的时域资源,所述网络设备和终端设备均在已经配置好的所述第五控制资源集合上传输或接收控制信息,在存在第一时域资源位置对控制信息传输不可用的情况下,不改变控制资源集合的时频资源位置。
进一步地,若第五控制资源集合中包含了第一时域资源位置中的时域资源,网络设备仍然可以改变并确定除时频位置之外的其他相关配置和/或参数,或者不改变,终端设备可以根据所述至少一个指示信息,确定所述其他相关的配置和/或参数,所述配置和/或参数可以为控制资源集合中REG绑定(REG bundle)类型或大小、控制资源集合的传输类型、资源单元组绑定的资源映射方式以及搜索空间配置信息中的一个或多个。
可选的,在网络设备发送所述至少一个指示信息(对于终端设备为接收)之前和之后,所述相关的配置或参数不发生改变。
可选的,在网络设备所述至少一个指示信息发送(对于终端设备为接收)之前和之 后,所述相关的配置和/或参数发生改变。上述配置和/或参数的改变可以参考本发明实施例1中的阐述,尽管第五控制资源集合的时域资源未发生改变,但是网络设备和终端设备可以基于所述第五控制资源集合中包含的第一时域资源位置中的时域资源,例如一个或多个对于控制信息传输不可用的时域符号,重新确定上述配置和/或参数。
一种实现中,如本发明实施例1相关部分(步骤605-607)的阐述,终端设备可以根据预先配置的规则进行相应的确定,或者根据网络设备下发的配置信息确定;若根据所述预先配置的规则进行处理,则所述预先配置的规则可以是标准或协议规定的,也可以是网络设备根据不同的传输场景或传输需要确定的,并已经提前通知或发送给所述终端设备。
另一种实现中,如本发明实施例1相关部分(步骤605-607)的阐述,根据以下进行示例性的阐述和说明确定上述配置和/或参数,以“之前的”的表述来标识在发送或接收所述至少一个指示信息之前,并将发送或接收到所述至少一个指示之后的第五控制资源集合叫做第六控制资源集合,仅进行名称上的区分;对于该实现方式的理解,可以参考本发明实施例1中相关的阐述,发送或接收所述至少一个第一指示信息之后的第六控制资源集合可以对应于第二控制资源集合,之前的第五控制资源集合可以对应于第一控制资源集合。
本发明实施例2的方法中,在所述终端设备接收所述至少一个指示信息之后,所述方法还包括以下步骤中的至少一个:
步骤705:所述终端设备确定所述第六控制资源集合的资源单元组绑定(REG Bundle)的映射方式,所述映射方式为频域优先映射。
一种可选的设计中,在所述终端设备接收所述至少一个指示信息之前,所述第五控制资源集合的资源单元组绑定(REG Bundle)的映射方式也为频域优先映射。
这种可选的设计中,不改变第五控制资源集合之前的资源单元组绑定的映射方式。
又一种可选的设计中,在所述终端设备接收所述至少一个指示信息之前,所述第五控制资源集合的资源单元组绑定(REG Bundle)的映射方式为时域优先映射。
在该可选的设计中,由于第五控制资源集合中包含了对于控制信息传输不可用的时域资源,为了提高终端设备检测的准确性,降低控制信息检测时延,REG Bundle的映射方式改变为频域优先映射。
例如,第五控制资源集合的REG Bundle映射方式为时域优先映射,REG Bundle大小为6个REG,例如REG Bundle在时域上占用一个时隙中的前3个符号,即时域上包含连续3个REG,频域上包含两个连续的REG,{3*2},若所述至少一个指示信息指示所述时隙中的第3个符号对于传输资源不可用,则确定所述第六控制资源集合的REG Bundle映射方式为频域优先映射,即,REG Bundle在时域上占用一个时隙中的前2个符号,即时域上包含连续2个REG,频域上包含3个连续的REG,{2*3}。这种设计可以避免一个REG Bundle中部分REG占用对于传输资源不用的时域资源,影响终端设备检测的准确性。
步骤706:所述终端设备确定所述第六控制资源集合的资源单元组绑定(REG Bundle) 中资源单元组的数量。
一种可选的设计中,若确定第六控制资源集合的资源大小小于第一阈值,或者,无法支持所述第五控制资源集合之前所支持的部分或全部聚合等级,则所述终端设备确定所述第六控制资源集合中资源单元组绑定(REG Bundle)中的资源单元组的数量小于所述第五控制资源集合中之前REG Bundle中的REG的数量。这种设计,使得在控制资源集合的资源大小变小的情况下,减少REG Bundle中REG的数量,优化了REG Bundle的设置。
步骤707:所述终端设备确定所述第六控制资源集合的搜索空间配置信息,所述搜索空间配置信息包含候选控制信道数量、聚合等级以及下行控制信息格式中的一个或多个。
一种可选的设计中,所述第五控制资源集合的搜索空间沿用接收到所述至少一个指示信息之前所述网络设备为所述第五控制资源集合配置的搜索空间,所述搜索空间配置信息为所述网络设备在发送所述至少一个指示信息之前的所述第五控制资源集合的搜索空间配置信息。
另一种可选的设计中,所述终端设备根据所述第一时域资源位置,确定所述第五控制资源集合中对于控制信息传输不可用的时域资源位置,获取第六控制资源集合,根据所述第六控制资源集合确定所述第六控制资源集合的搜索空间配置信息。
可选的,若所述终端设备确定所述第六控制资源集合包含的资源大小小于第二阈值,则确定所述第六控制资源集合的搜索空间的配置信息与所述第五控制资源集合的第三搜索空间配置信息相同,或者确定所述第六控制资源集合的搜索空间的配置信息为第四搜索空间配置信息,所述第四搜索空间配置信息是所述终端设备从所述网络设备接收的,或者根据预先设置的规则确定的,这里关于配置信息和预先设置的规则的解释参见上文中类似表述部分的阐述。
可选的,若所述终端设备确定所述第六控制资源集合包含的资源大小不小于第二阈值,则确定所述第六控制资源集合的搜索空间的配置信息与所述第五控制资源集合的第三搜索空间配置信息相同,或者确定所述第六控制资源集合的搜索空间的配置信息为第四搜索空间配置信息,所述第四搜索空间配置信息是所述终端设备从所述网络设备接收的,或者根据预先设置的规则确定的。
需要说明的是,用于控制信息传输的第五控制资源集合并未实质调整为所述第六控制资源集合,所述终端设备根据所述第一时域资源位置,能够确定不可用的时域资源位置,进而根据所述第六控制资源集合确定上述配置和/或参数,例如REG Bundle的大小或类型、REG Bundle的资源映射方式以及搜索空间配置信息中的一个或多个,并在所述第六控制资源集合上接收控制信息。
上述主要从各个网元之间交互的角度对本发明实施例提供的方案进行了介绍。可以理解的是,各个网元,例如网络设备、终端设备等为了实现上述功能,其包含了执行各个功能相应的硬件结构和/或软件模块。本领域技术人员应该很容易意识到,结合本文中所公开的实施例描述的各示例的单元及算法步骤,本发明能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行,取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用来使用不同方法 来实现所描述的功能,但是这种实现不应认为超出本发明的范围。
