Description

一种通信方法、装置以及系统 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资源块集合的配置。
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。
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，向终端设备发送下行控制信道。下行控制信道包括一个或多个控制信道单元(Control-channel elements,CCE)，下行控制信道单元CCE映射到CORESET，其中，控制资源集合在频域上包括连续或离散的频域资源，时域上包括多个连续OFDM符号。一个控制信道单元(CCE)由多个资源单元组(Resource element group,REG)构成。
在CCE映射到CORESET的过程中，由于CORESET在频域上包括连续或离散的频域资源，有可能存在将不同的CCE映射到相同的资源上的情况，导致控制信息的收发失败。因此如何实现CCE到CORESET上的映射，以实现准确、高效的资源配置是亟需解决的一个技术问题。

具体实施方式
本发明实施例描述的网络架构以及业务场景是为了更加清楚的说明本发明实施例的技术方案，并不构成对于本发明实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本发明实施例提供的技术方案对于类似的技术问题，同样适用。
本发明实施例中，“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：可以适用于长期演进(Long Term Evolution,简称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，或者网络设备，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。

控制资源集合(Control Resource Set，CORESET)：用于控制信道传输的资源集合，CORESET的时域资源可以连续或者不连续。
资源块(Resource Block，RB)：或者物理资源块，一种频域资源的单位，频域上占用连续的M个子载波，M为大于零的自然数。例如，LTE中，一个RB在频域上占用连续的12个子载波。
资源单元组(Resource Element Group，REG)：一种时频资源的单位。例如，一个REG在频域上占用1个资源块、时域上占用1个OFDM符号。
资源单元组绑定(Resource Element Group Bundle，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可以包括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。
高层信令：区分于物理层信令，可以为主信息块(Master Information Block,MIB)，系统信息块(System Information Block，SIB)，或无线资源控制(Radio Resource Control,RRC)信令，或其他具有类似特征的高层信令。
带宽区域：BandWidth Part(BWP)，频域连续的多个物理资源块，一般由网络设备为终端设备配置。终端设备在BWP内接收或发送数据。以控制资源传输为例，在一个BWP 内包括至少一个控制资源集合，且控制资源集合包括的频域资源不超过BWP在频域上包括的多个物理资源块。

在一个设计中，调制解调器处理器(modem processor)304可包括编码器3041，调制器3042，解码器3043，解调器3044。编码器3041用于对待发送信号进行编码。 例如，编码器3041可用于接收要在上行链路上发送的业务数据和/或信令消息，并对业务数据和信令消息进行处理(例如，格式化、编码、或交织等)。调制器3042用于对编码器3041的输出信号进行调制。例如，调制器可对编码器的输出信号(数据和/或信令)进行符号映射和/或调制等处理，并提供输出采样。解调器3044用于对输入信号进行解调处理。例如，解调器3044处理输入采样并提供符号估计。解码器3043用于对解调后的输入信号进行解码。例如，解码器3043对解调后的输入信号解交织、和/或解码等处理，并输出解码后的信号(数据和/或信令)。编码器3041、调制器3042、解调器3044和解码器3043可以由合成的调制解调处理器304来实现。这些单元根据无线接入网采用的无线接入技术来进行处理。
调制解调器处理器304从应用处理器302接收可表示语音、数据或控制信息的数字化数据，并对这些数字化数据处理后以供传输。所属调制解调器处理器可以支持多种通信系统的多种无线通信协议中的一种或多种，例如LTE,新空口，通用移动通信系统(Universal Mobile Telecommunications System，UMTS)，高速分组接入(High Speed Packet Access，HSPA)等等。可选的，调制解调器处理器304中也可以包括一个或多个存储器。

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CCE组成。一个CCE由多个REG组成，例如每个CCE包括6个REG。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。且由下式给出，

r＝0,1,...,R-1
c＝0,1,...,C-1

其中，R∈{2,3,6}，

为控制资源集合包括的REG个数，上述L、R以及n shift中的一个或多个可以根据高层信令的配置信息确定。
上述技术中，交织器函数f(.)不适用所有可能的配置情况，尤其在
Figure PCTCN2018123658-appb-000059
无法被L和R的乘积整除下，交织器函数的输出取值会出现多次重复的取值。如图4的控制资源集合所示。
控制资源集合包括频域连续的24个资源块、时域连续的2个OFDM符号，控制资源集合包括的REG的个数为2x24＝48，即：
Figure PCTCN2018123658-appb-000060
在一个CCE包括6个REG的情况下，CORESET内共包括8个CCE，编号为{0,1,2,3,4,5,6,7}；若通过高层信令的配置，确定n shift＝0，L＝6，R＝6；则CORESET内CCE 0对应的REG绑定为{f(0)}，CCE 1对应的REG绑定为{f(1)}，CCE 2对应的REG绑定为{f(2)}，CCE 3对应的REG绑定为{f(3)}，CCE 4对应的REG绑定为{f(4)}，CCE 5对应的REG绑定为{f(5)}，CCE 6对应的REG绑定为{f(6)}，CCE 7对应的REG绑定为{f(7)}。f(.)的表示式如公式(1)所示。
若f(x＝1),R＝6，则c＝0,r＝1(x＝cR+r)；进一步，
Figure PCTCN2018123658-appb-000061
(C·R)＝12，大于CORESET中的REG绑定个数8。
依此类推，得：

由上可知，f(x＝0)与f(x＝4)的取值相同，f(x＝1)和f(x＝5)的取值相同。由于交织函数的取值存在重复，将导致不同编号的CCE映射到相同的REG绑定上，造成控制信息发送和/或接收的失败。
本发明的实施例提供一种通信方法，网络设备确定控制资源集合中的M个资源单元组REG绑定，向终端设备发送控制信道；所述终端设备确定所述M个REG绑定，并在所述M个REG绑定对应的资源上检测控制信道。通过该通信方法，实现了通信系统中准确、高效的资源配置，提高了通信效率。
需要说明的是，本发明实施例中涉及的“第一”、“第二”等类似表述，仅用于举例，并不引入顺序或者编号上的限定。
需要说明的是，本发明实施例中确定的REG绑定的位置或者f(x)输出的结果为构成CCE的M个REG绑定在控制资源集合内的位置，具体的值可以为REG绑定的编号或者索引。具体阐述过程中，位置、编号、索引三者可以互相替代。
需要说明的是，本发明实施例中的“获取”操作，可以是确定或者接收。
还需要说明的是，本发明实施例涉及资源位置映射，不可避免的会涉及大量参数、中间变量以及公式。但是本发明实施例所涉及的“确定”操作并非仅仅局限于根据实施例所涉及的参数、中间变量和公式确定，而是根据公式所体现的技术构思确定。也就是说，本发明实施例所涉及的参数、中间变量、公式都不应当仅仅限制在参数、变量和公式本身，方案的范围应覆盖根据具体参数、中间变量所表达的技术含义所确定的范围，并且公式的计算也不仅仅限制在公式本身，本领域技术人员在所述公式基础上进行合理变型，但仍能得到公式所实现的结果或解决相同或相似的技术问题的构思和方案也应该本发明实施例的覆盖范围之内。
另外，本领域技术人员可知，对于M3的值满足M3＝M1 mod M2时，若M1的值 小于M2的值，则M3的值满足M3＝M1 mod M2即等同于M3的值满足M3＝M1。
图5示出了本发明实施例中通信方法的一种具体实现方式，如下根据图5对本发明的实施例提供的方案进行说明。
为方便阐述，本发明实施例中资源分配的交织处理以矩阵交织器的方式体现，矩阵交织器的大小通过矩阵的行列值体现。通过矩阵交织器的处理，控制资源集合上逻辑划分的一个或多个CCE，被映射到相应的物理资源REG绑定上，以实现下行信息的发送和接收。
步骤500：网络设备确定控制资源集合中的M个资源单元组REG绑定。所述控制资源集合由B个REG绑定组成。
该确定步骤可由网络设备的处理器201执行。
步骤501：所述网络设备在所述M个REG绑定对应的资源上，向终端设备发送下行信息。所述下行信息可以为控制信道和/或数据信道等。
该步骤可以网络设备的收发器202执行，或者由网络设备的处理器201控制收发器202执行。
其中，所述控制资源集合包括N个REG，所述N个REG在逻辑上被划分为一个或多个CCE，所述一个或多个CCE的编号按照大小顺序排列。每个CCE包括的REG数量为S，所述M个REG绑定组成所述控制资源集合中的第一控制信道单元CCE(从编号顺序上对应于第j+1个)，所述第一CCE的编号为j，所述j∈{0,1,…,N/S-1}。其中，所述L为REG绑定的大小，B等于N/L、M大于或者等于1。
步骤502，所述终端设备确定所述控制资源集合中M个资源单元组REG绑定。
该确定步骤可由终端设备的处理器304执行。
步骤503：所述终端设备在所述M个REG绑定对应的资源上检测控制信道。
上述步骤503也可以表述为所述终端设备在所述M个REG绑定对应的资源上检测并接收控制信道，或者表述为所述终端设备在所述M个REG绑定对应的资源上接收控制信道。
该确定步骤可由终端设备的处理器304执行，或者由收发器301执行，再或者由处理器304控制收发器301执行。
通过上述步骤500-503所实现的通信方法，可以实现通信系统中准确、高效的资源配置，提高了通信效率。
需要说明的是，本发明实施例中所涉及的网络设备的确定操作可以通过处理器201执行，网络设备的收发操作可以通过收发器202执行，或者通过处理器201控制收发器202执行；终端设备的确定操作可以通过处理器304执行，终端设备的获取操作可以通过处理器304或者收发器301执行，或者由处理器304控制收发器301执行，具体视获取方式而定，终端设备的收发操作可以通过收发器301执行。
本发明实施例中，网络设备配置控制资源集合，所述控制资源集合可以通过高层信 令配置，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，终端设备可以根据所述高层信令的配置获取控制资源集合。可选的，所述控制资源集合的配置包括但不限于频域资源位置以及时域长度，所述频域资源位置和时域长度可以用于确定所述控制资源集合包括的REG个数N。终端设备可以通过其它方式获取所述N的值，本发明实施例不做限定。
进一步可选的，所述网络设备配置所述控制资源集合中的REG绑定的大小L，即一个REG绑定包括的REG个数。可选的，所述L的取值范围为{2,3,6}。所述配置可以通过高层信令完成。
进一步可选的，每个CCE包括的REG数量为S。所述S可以是预先配置或定义的，例如，标准或协议中规定的，也可以是网络设备配置的。可选的，所述S的值为6。
这里需要说明的是，NR系统中采用矩形交织器进行资源配置或映射，通过矩形交织器产生矩阵，所述矩阵中的行列位置用于以REG绑定为粒度的映射。一般来说，矩阵交织器的输入和输出以行进列出的方式进行，参见图6。例如，编号0-5以{0,1,2,3,4,5}的顺序输入到交织器中，以行优先的顺序经过矩阵交织，以列优先的顺序输出，输出的编号为{0,2,4,1,3,5}。下面为阐述方便，将矩阵的行数称为R(Row)，列数称为C(Column)；进一步，r∈{0,1,...,R-1}(又称作行编号)，c∈{0,1,...,C-1}(又称作列编号)。可选的，所述R是网络设备配置的，也称作交织参数，例如，通过高层信令配置；所述C可以为网络设备配置的，也可以是通过网络设备的配置隐式指示的，所述C的值等于
Figure PCTCN2018123658-appb-000070
需要说明的是，本发明实施例中所涉及的L、N、C、R、B的含义相同，具体参见上文的阐述。
本发明实施例中，在采用矩形交织器进行资源配置或映射时，所述矩阵的大小为C·R，所述控制资源集合包括的REG绑定个数为B。在所述矩阵大小与B相等时，可以实现完整映射，不会出现映射位置冲突；在所述矩阵大小大于B时，为避免不同的CCE映射到相同的REG绑定上而导致资源冲突，则需要准确、高效的确定REG绑定的映射位置。
下述的阐述中涉及到的共同特征解释如下：
f(x):用于指示编号为x的REG绑定的索引，或者叫做交织器或交织器函数；
g(x)：用于指示编号为x的REG绑定的索引，区别于f(x)，可以为现有技术中的交织器或者交织器函数。例如，所述g(x)＝h(x)mod B，或者，g(x)＝h(x)(这里需要说明的是，当h(x)的值小于B时，g(x)＝h(x)mod B＝h(x))。
进一步，所述g(x)的值可以为：
g(x)＝h(x)modB＝(rC+c+n shift)mod(N/L)
x＝cR+r
r∈{0,1,...,R-1}；这里，
c∈{0,1,...,C-1}
h(x)＝rC+c+n shift。
可选的，当h(x)的值小于B时：g(x)＝h(x)＝(r·C+c)；为与上述公式区分，将这里的(r·C+c)定义为u(k)，即u(k)＝(r·C+c)。其中：
c和r的值满足：k＝cR+r(或者，k＝cR+r+offset6，offset6的取值参见下文中的阐述)；
所述k的值满足k＝(x+n shift)mod(B)，或者，k＝(x-n shift)mod(B),或者x＝(k+n shift)mod(B)，或者x＝(k-n shift)mod(B)。
其中，所述n shift的值是终端设备或网络设备确定的，例如可以为预先定义或配置的，也可以是网络设备配置的，还可以是终端设备根据网络设备的配置确定，或者根据一定的规则确定，可以根据不同的场景进行不同的设计。例如，所述终端设备通过高层信令配置的参数，根据预定的规则或者函数，确定所述n shift的值。基于上述公式，根据z和R，可以确定r和c的值，进一步得到g(x)的值。所述n shift的具体解释可以参见下文中第二种可选的设计的阐述。
上述步骤500和502中，所述网络设备和所述终端设备分别确定控制资源集合中M个资源单元组REG绑定。所述网络设备和终端设备确定所述控制资源集合中第j+1个控制信道单元CCE中的第i+1个REG绑定的索引为f(x)，所述x的值等于(6j/L+i)。
第一种可选的设计中，根据至少一个偏移值确定所述M个REG绑定，所述至少一个偏移值可以根据矩阵大小与B的差值，即((C·R)-B)确定，后续称((C·R)-B)为N null，即空元(或者称为REG绑定的编号重复的位置)的个数，所述空元即终端设备忽略或者不读取的位置，这些位置不与所述控制信道单元中的CCE映射。参见图7。控制信道单元中的REG绑定的编号以行优先的方式输入到交织矩阵中，并以列优先的方式从交织矩阵输出。在所述矩阵大小大于B时，为避免资源映射冲突，矩阵中REG绑定的映射位置以及空元的个数以及位置存在多种配置方式。所述至少一个偏移值包括offset1、offset2、offset3、offset4、offset5以及offset6中的一个或多个。该第一种可选的设计中存在多种可选的实现，下面针对该多种可选的实现分别阐述。进一步可选的，所述至少一个偏移值中的任一个或多个偏移值可以根据
Figure PCTCN2018123658-appb-000071
的值，以及行编号r和列编号c中的至少一个确定。即，所述至少一个偏移值中的任一个或多个偏移值是根据
Figure PCTCN2018123658-appb-000072
的值以及行编号r确定的，或者，所述至少一个偏移值中的任一个或多个偏移值是根据
Figure PCTCN2018123658-appb-000073
的值以及列编号c确定的，或者，所述至 少一个偏移值中的任一个或多个偏移值是根据
Figure PCTCN2018123658-appb-000074
的值以及行编号r和列编号c确定的。
第一种可选的实现中，所述至少一个偏移值包括offset1。在该可选的实现中所述空元(REG绑定的编号重复的位置)的位置在矩阵中最后一行的尾部。所述M个REG绑定索引的确定需要避开最后一行的尾部，即矩阵的输出不能包含该矩阵最后一行尾部的N null个位置，具体参见图7。
可选的，f(x)的值满足f(x)＝g(x+offset1)。
可选的，f(x)的值满足f(x)＝(rC+c+n shift)mod B，x＝cR+r-offset1。
在上述两种可选的方式中，根据N null的不同，offset1的取值存在区别，具体参见以下阐述。
当N null＝0时，f(x)＝g(x)。
当N null≠0时，参见以下两种情况下的取值：
第一种情况、C≥N null，则offset1＝n，f(x)＝g(x+n)，n的取值满足：a n≤x<a n+1，所述n∈{0,1,...N null-1}；
其中，

所述N null＝(C·R-B)，所述
Figure PCTCN2018123658-appb-000076
第二种情况、C<N null，则offert1＝n·W n，f(x)＝g(x+n·W n)，该情况中的n与第一种情况中的n含义不同，具体参见相应解释。n的取值满足：b n≤x<b n+1，所述n∈{0,1,...,C-1}；
其中，
Figure PCTCN2018123658-appb-000077
所述
Figure PCTCN2018123658-appb-000078
参见例1，控制资源集合包括频域连续的21个资源块、时域连续的2个OFDM符号，进而控制资源集合包括的REG的个数为2x 21＝42，即：N＝42；CCE包括6个REG，若CORESET内共包括7个CCE，编号为{0,1,2,3,4,5,6}；若通过高层信令的配置，确定n shift＝0，L＝6，R＝3；则CORESET内CCE 0对应的REG绑定为{f(0)}，CCE 1对应的REG绑定为{f(1)}，CCE 2对应的REG绑定为{f(2)}，CCE 3对应的REG绑定为{f(3)}，CCE 4对应的REG绑定为{f(4)}，CCE 5对应的REG绑定为{f(5)}，CCE 6对应的REG绑定为{f(6)}。
若g(x＝1),R＝3，则根据x＝cR+r可知，c＝0,r＝1；进一步，B＝7，C＝3；则根据g(x)＝(rC+c+n shift)mod(N/L)，可知：
g(x＝0)＝(rC+c)mod(N/L)＝(0x3+0)mod(42/6)＝0；
g(x＝1)＝(rC+c)mod(N/L)＝(1x3+0)mod(42/6)＝3；
g(x＝2)＝(rC+c)mod(N/L)＝(2x3+0)mod(42/6)＝6；
g(x＝3)＝(rC+c)mod(N/L)＝(0x3+1)mod(42/6)＝1；
g(x＝4)＝(rC+c)mod(N/L)＝(1x3+1)mod(42/6)＝4；
g(x＝5)＝(rC+c)mod(N/L)＝(2x3+1)mod(42/6)＝0；
g(x＝6)＝(rC+c)mod(N/L)＝(0x3+2)mod(42/6)＝2；
g(x＝7)＝(rC+c)mod(N/L)＝(1x3+2)mod(42/6)＝5；
g(x＝8)＝(rC+c)mod(N/L)＝(2x3+2)mod(42/6)＝1；
由于f(x)的值满足f(x)＝g(x+n)，n∈{0,1}，根据a0＝0，a1＝R·(C-N null)+(R-1)＝5，a2＝R·(C-N null)+2(R-1)＝7可知：
当0≤x<5时，n＝0，所述f(x)的值如下：
f(0)＝g(0+0)＝0；f(1)＝g(1+0)＝3；f(2)＝g(2+0)＝6；f(3)＝g(3+0)＝1；f(4)＝g(4+0)＝4；
当5≤x<7时，n＝1，所述f(x)的值如下：
f(5)＝g(5+1)＝g(6)＝2；f(6)＝g(6+1)＝g(7)＝5。参见图7，上述确定的M个REG绑定的索引不包含空元(或REG绑定编号重复)的位置。
通过该实现方式，可以实现组成下行控制信道的一个或多个CCE映射到控制资源集合内的REG绑定时，尽可能的分散在整个控制资源集合内，进而下行控制信道的发送/接收可以获得较大的频率分集增益。
第二种可选的实现中，所述至少一个偏移值包括offset2，进一步还可以包括offset6，其中：
所述f(x)的值满足f(x)＝(h(x)-offset2)mod B，其中，x＝cR+r，h(x)＝rC+c+n shift，N null＝(C·R-B)，
Figure PCTCN2018123658-appb-000079
r∈{0,1,…(R-1)}，c∈{0,1,…(C-1)}；
或者
f(x)的值满足
Figure PCTCN2018123658-appb-000080
或者，
所述f(x)的值满足f(x)＝h(x)-offset2(这里需要说明的是，当(h(x)-offset2)的值小于B时，f(x)＝(h(x)-offset2)mod B＝h(x)-offset2)。
可选的，所述h(x)的值满足：h(x)＝u(k)；
所述u(k)的值等于(r·C+c)，所述k的值满足k＝(x+n shift)mod(B)，或者，(x-n shift)mod(B)，或者x＝(k+n shift)mod(B)，或者x＝(k-n shift)mod(B)，并且，c和r的值满足：k＝cR+r，或者，k＝cR+r+offset6；
其中，所述n shift为移位值，可以为终端设备或网络设备确定的，具体的解释可以参见下文中第二种可选的设计中的阐述。
对于offset2的值：
一种可选的，所述offset2＝max{0，r-(R-N null)}，或者，offset2＝ max{0,(xmodR)-(R-N null)}。该可选的方式中，空元的位置位于矩阵的最后一列的尾部，参见图7。所述M个REG绑定索引的确定需要避开最后一列的尾部，即矩阵的输出不能包含该矩阵最后一列尾部的N null个位置。
参见例2，控制资源集合包括频域连续的21个资源块、时域连续的2个OFDM符号，进而控制资源集合包括的REG的个数为2x 21＝42，即：N＝42；当CCE包括6个REG时，CORESET内共包括7个CCE，编号为{0,1,2,3,4,5,6}；若通过高层信令的配置，确定n shift＝0，L＝6，R＝3；则CORESET内CCE 0对应的REG绑定为{f(0)}，CCE 1对应的REG绑定为{f(1)}，CCE 2对应的REG绑定为{f(2)}，CCE 3对应的REG绑定为{f(3)}，CCE 4对应的REG绑定为{f(4)}，CCE 5对应的REG绑定为{f(5)}，CCE 6对应的REG绑定为{f(6)}。
若f(x＝1),R＝3，则根据x＝cR+r可知，c＝0,r＝1；进一步，B＝7，C＝3，N null＝2，offset2＝max{0,r-(R-N null)}＝max{0,1-1}＝0。
则基于上述阐述可知：
f(x＝0)＝(rC+c+n shift-offset2)mod B＝(0x3+0-0)mod(42/6)＝0；
f(x＝1)＝(rC+c+n shift-offset2)mod B＝(1x3+0-0)mod(42/6)＝3；
f(x＝2)＝(rC+c+n shift-offset2)mod B＝(2x3+0-1)mod(42/6)＝5；
f(x＝3)＝(rC+c+n shift-offset2)mod B＝(0x3+1-0)mod(42/6)＝1；
f(x＝4)＝(rC+c+n shift-offset2)mod B＝(1x3+1-0)mod(42/6)＝4；
f(x＝5)＝(rC+c+n shift-offset2)mod B＝(2x3+1-1)mod(42/6)＝6；
f(x＝6)＝(rC+c+n shift-offset2)mod B＝(0x3+2-0)mod(42/6)＝2。
基于上述实现，7个CCE映射到不同的REG绑定上，使得组成下行控制信道(PDCCH)的一个或多个CCE映射到控制资源集合内的REG绑定尽可能的分散在整个控制资源集合内，进而使得下行控制信道的发送/接收可获得较大的频率分集增益。
又一种可选的，所述
Figure PCTCN2018123658-appb-000081
该可选的方式中，空元的位置位于矩阵的最后一列的首部，所述M个REG绑定索引的确定需要避开最后一列的首部，即矩阵的输出不能包含该矩阵最后一列首部的N null个位置，参见图8。
参见例3，控制资源集合包括频域连续的21个资源块、时域连续的2个OFDM符号，进而控制资源集合包括的REG的个数为2x 21＝42，即：N＝42；当CCE包括6个REG时，CORESET内共包括7个CCE，编号为{0,1,2,3,4,5,6}；若通过高层信令的配置，确定n shift＝0，L＝6，R＝3；则CORESET内CCE 0对应的REG绑定为{f(0)}，CCE 1对应的REG绑定为{f(1)}，CCE 2对应的REG绑定为{f(2)}，CCE 3对应的REG绑定为{f(3)}，CCE 4对应的REG绑定为{f(4)}，CCE 5对应的REG绑定为{f(5)}，CCE 6对应的REG绑定为{f(6)}。
若f(x＝1),R＝3，则根据x＝cR+r可知c＝0,r＝1；进一步，B＝7，C＝3，N null＝2，c<C-1，则offset2＝max{r,N null}＝min{1,2}＝1。
则基于上述阐述可知：
f(x＝0)＝(rC+c+n shift-offset2)mod B＝(0x3+0-0)mod(42/6)＝0；
f(x＝1)＝(rC+c+n shift-offset2)mod B＝(1x3+0-1)mod(42/6)＝2；
f(x＝2)＝(rC+c+n shift-offset2)mod B＝(2x3+0-2)mod(42/6)＝4；
f(x＝3)＝(rC+c+n shift-offset2)mod B＝(0x3+1-0)mod(42/6)＝1；
f(x＝4)＝(rC+c+n shift-offset2)mod B＝(1x3+1-1)mod(42/6)＝3；
f(x＝5)＝(rC+c+n shift-offset2)mod B＝(2x3+1-2)mod(42/6)＝5；
f(x＝6)＝(rC+c+n shift-offset2)mod B＝(0x3+2-2+3x2)mod(42/6)＝6。
再一可选的，所述offset2的值满足offset2＝N null,其中N null满足

对于offset6的值：
当c∈{0,1,2,…,N null-1}时，offset6的值满足offset6＝(-c-1)，其中，r∈{1,2,…,R-1}；和/或

其中，所述n shift为移位值，可以为终端设备或网络设备确定的，具体的解释可以参见下文中第二种可选的设计中的阐述。
一种可选的，所述offset3＝min{0,(R-N null)-r)}，或者，offset3＝min{0,(R-N null)-(x mod R)}。该可选的方式中，空元的位置位于矩阵的最后一列的尾部，参见图7。所述M个REG绑定索引的确定需要避开最后一列的尾部，即矩阵的输出不能包含该矩阵最后一列尾部的N null个位置。
参见例4，控制资源集合包括频域连续的21个资源块、时域连续的2个OFDM符号，进而控制资源集合包括的REG的个数为2x 21＝42，即：N＝42；当CCE包括6 个REG时，CORESET内共包括7个CCE，编号为{0,1,2,3,4,5,6}；若通过高层信令的配置，确定n shift＝0，L＝6，R＝3；则CORESET内CCE 0对应的REG绑定为{f(0)}，CCE 1对应的REG绑定为{f(1)}，CCE 2对应的REG绑定为{f(2)}，CCE 3对应的REG绑定为{f(3)}，CCE 4对应的REG绑定为{f(4)}，CCE 5对应的REG绑定为{f(5)}，CCE 6对应的REG绑定为{f(6)}。
若f(x＝1),R＝3，则根据x＝cR+r可知c＝0,r＝1；进一步，B＝7，C＝3,N null＝2，则offset3＝min{0,(R-N null)-r}＝min{0,1-1}＝0。
则基于上述阐述可知：

该可选的方式中，空元的位置位于矩阵的最后一列的首部，参见图8。所述M个REG绑定索引的确定需要避开最后一列的首部，即矩阵的输出不能包含该矩阵最后一列首部的N null个位置。
参见与例4相同的控制资源集合的配置，控制资源集合包括REG的个数为2x 21＝42；若高层信令配置的n shift＝0，L＝6，R＝3。
若f(x＝1),R＝3，则c＝0,r＝1；进一步，B＝7，C＝3,N null＝2，c<C-1，则offset3＝max{-r,-N null}＝max{-1,-2}＝-1。
则基于上述阐述可知：
f(x＝0)＝(rC+c+n shift+offset3)mod B＝(0x3+0-0)mod(42/6)＝0；
f(x＝1)＝(rC+c+n shift+offset3)mod B＝(1x3+0-1)mod(42/6)＝2；
f(x＝2)＝(rC+c+n shift+offset3)mod B＝(2x3+0-2)mod(42/6)＝4；
f(x＝3)＝(rC+c+n shift+offset3)mod B＝(0x3+1-0)mod(42/6)＝1；

该第三种实现中，所述A属于{2,4}、{2,3,6}、{1,2,4}、{1,2,3,6}、{1,2,3,4,6}或者{1}，所述Z属于{2,4}、{1,2,4}、{2,3,6}、{1,2,3,6}或者{1}，所述Z、A以及n id的解释参见第一和第二种实现。
第三种可选的设计中，结合上述第一和第二种可选的设计确定所述M个REG绑定。所述第二种可选的设计中的移位值包括的n shift，可以直接应用于第一种可选的设计。
第四种可选的设计中，所述网络设备和终端设备确定所述控制资源集合中第j+1个控制信道单元CCE中的第i+1个REG绑定的索引为f(x)，所述x的值等于(6j/L+i)，所述f(x)的值满足f(x)＝(rC+c+n shift)mod(C·R)，或者，f(x)＝(rC+c+n shift)mod B，并且x∈{0,1,2,3,…,C·R-1}，针对所述x的取值集合，f(x)的取值集合为B个互不相同且小于B的位置。
当所述f(x)的值满足f(x)＝(rC+c+n shift)mod(C·R)时，所述CCE中的REG绑定的编号(逻辑上的索引)x按行写入矩阵，x∈{0,1,2,3,…,C·R-1}，矩阵的输出为B个互不相同且小于B的REG绑定的位置或索引。矩阵映射过程中，若针对某一输入参数x， 得到的值大于或者等于B，则矩阵不输出所述值，而是针对下一个输入的参数继续计算，直到矩阵输出B个互不相同且小于B的位置。
以图4所述的矩阵为例，具体参数参见针对图4的阐述。CORESET内共包括8个CCE，编号为{0,1,2,3,4,5,6,7}；CCE 0对应的REG绑定为{f(0)}，CCE 1对应的REG绑定为{f(1)}，CCE 2对应的REG绑定为{f(2)}，CCE 3对应的REG绑定为{f(3)}，CCE 4对应的REG绑定为{f(4)}，CCE 5对应的REG绑定为{f(5)}，CCE 6对应的REG绑定为{f(6)},CCE 7对应的REG绑定为{f(7)}。即，B＝8，C·R＝12。在N null＝(C·R-B)不为0的情况下，存在N null个空元位置。若f(x)满足f(x)＝(rC+c+n shift)mod(C·R)，x的范围为{0,1,2，…，11}，相应的REG绑定位置确定如下。
具体的，f(x＝0)＝0，原对应于f(x＝4)的位置为8，等于B，忽略或者不输出，则对应于f(x＝4)的位置输出顺序上应对应f(x＝5)的值，即10，大于B，忽略或者不输出，继续计算直到f(x＝6)＝1。则对应于f(x＝4)的位置输出顺序上应对应f(x＝6)的值，即1。由于x作为输入参数，输入范围大于原输入范围，依次计算，得到的8个互不相同且小于8个输出{0,2,4,6,3,1,3,5,7}。
当f(x)的值满足f(x)＝(rC+c+n shift)modB时，所述CCE中的REG绑定的编号(逻辑上的索引)x按行写入矩阵，x∈{0,1,2,3,…,C·R-1}，矩阵的输出为B个互不相同且小于B的REG绑定的位置或索引。矩阵映射过程中，若针对某一输入参数x，得到的值与先前输入的参数对应的值相同，则矩阵不输出所述重复的值，而是针对下一个输入的编参数继续计算，直到矩阵输出B个互不相同且小于B的位置。
以图4所述的矩阵为例，具体参数参见针对图4的阐述。CORESET内共包括8个CCE，编号为{0,1,2,3,4,5,6,7}；CCE 0对应的REG绑定为{f(0)}，CCE 1对应的REG绑定为{f(1)}，CCE 2对应的REG绑定为{f(2)}，CCE 3对应的REG绑定为{f(3)}，CCE 4对应的REG绑定为{f(4)}，CCE 5对应的REG绑定为{f(5)}，CCE 6对应的REG绑定为{f(6)},CCE 7对应的REG绑定为{f(7)}。即，B＝8，C·R＝12。在N null＝(C·R-B)不为0的情况下，存在N null个空元位置。若f(x)满足f(x)＝(rC+c+n shift)modB，x的范围为{0,1,2，…，11}，相应的REG绑定位置确定如下。
具体的，f(x＝0)＝0，原对应于f(x＝4)的位置也为0，产生重复，则对应于f(x＝4)的位置输出顺序上应对应f(x＝5)的值，即2，同样与f(x＝1)的值重复。则对应于f(x＝4)的位置输出顺序上应对应f(x＝6)的值，即1。由于x作为输入参数，输入范围大于原输入范围，依次计算，得到的8个互不相同且小于8个输出{0,2,4,6,3,1,3,5,7}。
在可选的设计中，所述控制资源集合由B个资源单元组绑定组成；所述B的值小于或者等于(C·R)。在通过矩阵进行CCE到REG绑定的交织映射时，所述CCE中的REG绑定的编号(逻辑上的索引)按行写入矩阵，并按列读出映射后的物理REG绑定的索引。在B小于(C·R)时，空元的数量为N null＝(C·R-B)，空元的位置由如下可选的方式：
可选的，空元位于最后一列的后N null个行。
可选的，空元位于最后一列的前N null个行；
