Description

上行控制信息发送接收方法、装置及系统 技术领域
本发明实施例涉及通信技术领域，尤其涉及一种上行控制信息发送接收方法、装置及系统。
背景技术
在长期演进(Long Term Evolution，简称LTE)系统中，接入网设备通过多个载波中的至少一个载波向同一终端设备发送下行数据，该终端设备针对各载波上的下行数据分别进行确认并产生混合自动重传请求-确认HARQ-ACK信息，确认成功该终端设备返回确认信息ACK，确认失败该终端设备返回确认失败信息NACK，该终端设备通过同一上行信道向接入网设备发送各确认信息；另外，接入网设备分别通过各载波向该终端设备发送参考信号，以使该终端设备检测各载波上的参考信号获得各载波对应的信道状态信息(Channel State Information，简称CSI)。
现有技术中，接入网设备通过预配置的信息指示该终端设备反馈周期CSI的子帧位置(由反馈CSI的子帧偏置和反馈CSI的周期确定)以及在各反馈周期CSI的位置上反馈周期CSI的具体内容，此处将确认信息和/或CSI均称为上行控制信息(Uplink Control Information，简称UCI)，因此，该终端设备在某些子帧通过该上行信道向接入网设备反馈的UCI只包括确认信息或者只包括周期CSI信息，而在某些子帧反馈的UCI同时包括确认信息和CSI。由于该终端设备在反馈周期CSI的各个子帧上反馈的CSI比特数不固定，所以该终端设备在不同子帧反馈的UCI的比特数不同；接入网设备预先给该终端设备分配多条上行信道，且在该终端设备反馈UCI之前，接入网设备向该终端设备发送动态指示信息，该动态指示信息指定该终端设备反馈UCI的上行信道。
由于接入网设备预先给该终端设备分配的上行信道的数量不断增加，使得接入网设备下发的动态指示信息的比特数不断增加，导致下行信道资源消耗较大；另外，接入网设备通过动态指示信息为该终端设备指定的上 行信道的容量并不符合UCI的大小，导致上行信道的利用率较低或UCI比特被丢弃。
发明内容

所述终端设备确定所述一个信道资源集合中所述信道指示信息所指示的信道资源；
所述终端设备在所述信道资源上向所述接入网设备发送上行控制信息UCI。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
图1为本发明实施例提供的上行控制信息发送方法流程图。本发明实施例针对随着上行信道的数量不断增加，接入网设备下发的信道指示信息的比特数不断增加，导致下行信道资源消耗较大，提供了上行控制信息发送方法，该方法具体步骤如下：
步骤S101、终端设备通过物理控制信道从接入网设备接收信道指示信息；
本发明实施例涉及LTE系统中的接入网设备和终端设备，接入网设备具体为基站，接入网设备通过多个载波中的至少一个载波向同一终端设备发送下行数据，终端设备针对各载波上的下行数据分别进行确认并产生HARQ-ACK信息；另外，接入网设备分别通过各载波向该终端设备发送参考信号，终端设备通过检测各载波上的参考信号获得各载波对应的信道状态信息CSI，接入网设备通过上行信道向接入网设备反馈上行控制信息UCI，UCI包括HARQ-ACK信息和信道状态信息CSI中的至少一种。
在接入网设备通过上行信道向接入网设备反馈上行控制信息UCI之前，终端设备通过物理控制信道接收接入网设备发送的信道指示信息，物理控制信道具体为物理下行控制信道(Physical Downlink Control Channel，简称PDCCH)和增强的物理下行控制信道(Enhanced Physical Downlink Control Channel，简称EPDCCH)，且物理控制信道上承载的信息为动态配置的信息，即信道指示信息作为一种动态配置的信息承载在物理控制信道上，由接入网设备发送到终端设备。
步骤S102、所述终端设备从N个信道资源集合中确定一个信道资源集合为第一信道资源集合，其中，N为大于或等于2的正整数，所述N个信道资源集合为所述接入网设备预先为所述终端设备配置的，所述N个信道资源集合中每一个包括至少两个信道资源；
在本发明实施例中，可以先执行步骤S101后执行步骤S102，也可以先执行步骤S102后执行步骤S101，接入网设备预先为所述终端设备配置N个信道资源集合，N为大于或等于2的正整数，所述N个信道资源集合中每一个包括至少两个信道资源；终端设备从所述N个信道资源集合中确定一个信道资源集合为第一信道资源集合。具体地，从N个信道资源集合中确定一个信道资源集合为第一信道资源集合可依据终端设备向接入网设备反馈的UCI的类型或大小，UCI的类型具体可通过UCI包括的具体内容加以区别，UCI的大小具体可通过UCI的比特数或UCI的数量加以衡量。
步骤S103、所述终端设备确定所述第一信道资源集合中所述信道指示信息所指示的信道资源；
上述步骤S102确定出第一信道资源集合，然后所述终端设备确定所述第一信道资源集合中所述信道指示信息所指示的信道资源。具体地，所述信道指示信息指示的信道资源是所述第一信道资源集合中的信道资源。例如，第一信道资源集合包括信道资源a、信道资源b、信道资源c、信道资源d四个信道资源。预定义信道指示信息00指示信道资源a、信道指示信息01指示信道资源b、信道指示信息10指示信道资源c、信道指示信息11指示信道资源d。通过信道指示信息的指示便可以从第一信道资源集合中确定出所述信道资源。
步骤S104、所述终端设备在所述信道资源上向所述接入网设备发送上行控制信息UCI。
终端设备通过步骤S103确定的信道资源向所述接入网设备发送上行控制信息UCI，即所述信道资源作为上行信道承载上行控制信息UCI，并向接入网设备发送UCI。
本发明实施例通过接入网设备向终端设备发送包括至少两个信道资源集合的配置信息，每个信道资源集合包括至少两个信道资源，相当于将接入网设备分配给终端设备的所有信道资源进行分组，每组相当于一个信道资源集合，终端设备先从多个信道资源集合中确定出第一信道资源集合，再依据信道指示信息从第一信道资源集合中确定信道资源，根据同一信道指示信息在不同子帧时刻可以确定出不同的信道资源，而现有技术同一信道指示信息在不同子帧时刻只能确定一个信道资源，随着信道资源的数量不断增加，本发明实施例中信道指示信息需要增加的比特数小于现有技术中信道指示信息需要增加的比特数，减少了信道指示信息在下发过程中对下行信道资源的消耗。
图2为本发明实施例提供的信道资源的示意图。在上述实施例的基础上，所述终端设备从N个信道资源集合中确定一个信道资源集合为第一信道资源集合之前，还包括：所述终端设备确定所述UCI的类型；所述终端设备从N个信道资源集合中确定一个信道资源集合为第一信道资源集合，包括：所述终端设备从N个信道资源集合中确定与所述UCI的类型匹配的所述一个信道资源集合为第一信道资源集合。
所述UCI的类型包括第一类型和第二类型，N＝2；其中，第一类型的 UCI包括信道状态信息CSI与混合自动重传请求-确认HARQ-ACK信息，所述N个信道资源集合中的一个包括的信道资源是用于发送所述第一类型的UCI的；第二类型的UCI包括HARQ-ACK信息但不包括CSI，所述N个信道资源集合中的另一个包括的信道资源是用于发送所述第二类型的UCI的。
所述终端设备确定所述UCI的类型。对于所述终端设备的每一个下行载波有对应的周期CSI发送的配置信息。具体配置信息包括周期CSI的发送周期和在该周期内的发送所述周期CSI的子帧偏移值。所述UE通过所述基站配置的每个下行载波的周期CSI的发送周期和发送子帧偏移值，可以确定出当前上行子帧有没有至少一个载波的周期CSI需要发送。从而确定当前上行子帧需要反馈的UCI的类型是第一类型的UCI还是第二类型的UCI。
在本发明实施例中，第一类型的UCI包括信道状态信息CSI与混合自动重传请求-确认HARQ-ACK信息，第二类型的UCI包括HARQ-ACK信息但不包括CSI，N＝2，从N个信道资源集合中确定一个信道资源集合为第一信道资源集合具体可根据信道资源集合的类型与UCI类型的对应关系确定，具体有两种方式实现该对应关系，第一种方式为接入网设备预先为所述终端设备配置N个信道资源集合时，预定义每个信道资源集合所匹配的UCI的类型，例如每个信道资源集合中的信道资源用于发送第一类型的UCI还是用于发送第二类型的UCI；第二种方式为接入网设备预先为所述终端设备配置N个信道资源集合时，向终端设备发送控制信令来指示每个信道资源集合所匹配的UCI的类型，例如每个信道资源集合中的信道资源用于发送第一类型的UCI还是用于发送第二类型的UCI。
如图2所示，上述实施例中的配置信息包括两个信道资源集合：信道资源集合A和信道资源集合B，每一个信道资源集合与具体不同的UCI类型匹配。本发明实施例假设信道资源集合A与第一类型UCI匹配，信道资源集合B与第二类型UCI匹配。即信道资源集合A中的信道资源如信道资源1-1、信道资源1-2、信道资源1-3、信道资源1-4均可承载信道状态信息CSI和混合自动重传请求-确认HARQ-ACK信息。信道资源集合B中的信道资源如信道资源2-1、信道资源2-2、信道资源2-3、信道资源2-4可用 于承载混合自动重传请求-确认HARQ-ACK信息但不可用于承载CSI。
终端设备根据所述UCI的类型确定与所述UCI的类型匹配的一个信道资源集合为第一信道资源集合。具体确定过程为：若所述UCI中包括CSI，则终端设备确定与所述UCI的类型匹配的信道资源集合A为第一信道资源集合；若所述UCI中不包括所述CSI，则所述终端设备确定信道资源集合B为第一信道资源集合。
另外，预定义第一信道资源集合是信道资源集合A时，信道指示信息00指示信道资源1-1、信道指示信息01指示信道资源1-2、信道指示信息10指示信道资源1-3、信道指示信息11指示信道资源1-4。预定义第一信道资源集合是信道资源集合B时，信道指示信息00指示信道资源2-1、信道指示信息01指示信道资源2-2、信道指示信息10指示信道资源2-3、信道指示信息11指示信道资源2-4。
若确定出的第一信道资源集合是信道资源集合A，且信道指示信息携带的信道资源标识号为二进制数01，则终端设备按照信道指示信息从信道资源集合A中确定出的信道资源1-2。若确定出的第一信道资源集合是信道资源集合B，终端设备按照同一信道指示信息从信道资源集合B中确定出的信道资源为信道资源2-2，即同一信道指示信息在不同子帧时刻可以指示不同的目标信道资源。
本发明实施例具体给出了终端设备根据UCI的类型从两个信道资源集合中确定出与UCI的类型匹配的一个信道资源集合为第一信道资源集合的方法。
图3为本发明另一实施例提供的信道资源的示意图。所述终端设备从N个信道资源集合中确定一个信道资源集合为第一信道资源集合之前，还包括：所述终端设备确定所述UCI的大小；所述终端设备从N个信道资源集合中确定一个信道资源集合为第一信道资源集合，包括：所述终端设备从N个信道资源集合中确定与所述UCI的大小K匹配的所述一个信道资源集合为第一信道资源集合。
所述终端设备确定所述UCI的大小。对于所述终端设备的每一个下行载波有对应的周期CSI发送的配置信息。具体配置信息包括周期CSI的发送周期和在该周期内的发送所述周期CSI的子帧偏移值以及周期CSI的上 报模式等。所述UE通过所述基站配置的每个下行载波的周期CSI配置信息，可以确定出当前上行子帧对各载波进行周期CSI上报的比特数以及上报的内容。从而确定当前上行子帧需要反馈的UCI的大小K。
所述终端设备从N个信道资源集合中确定与所述UCI的大小K匹配的所述一个信道资源集合为第一信道资源集合，包括：所述终端设备确定所述N个信道资源集合中每个信道资源集合对应的容量范围；所述终端设备从N个信道资源集合中确定出所述一个信道资源集合为第一信道资源集合，以使所述UCI的大小K满足Rmin≤K≤Rmax，其中，所述一个信道资源集合的容量范围为[Rmin,Rmax]，所述Rmin为所述一个信道资源集合的容量的最小值，所述Rmax为所述一个信道资源集合的容量的最大值。
如图3所示，接入网设备预先为所述终端设备配置4个信道资源集合：信道资源集合A、信道资源集合B、信道资源集合C和信道资源集合D，接入网设备向终端设备发送配置信息，所述配置信息包括4个信道资源集合中每个信道资源集合对应的容量范围，且每个信道资源集合对应不同的容量范围。所述每个信道资源集合对应的容量范围指的是所述每个信道资源集合各自的信道资源中可以发送的UCI的比特数。例如，信道资源集合A对应的容量范围为[R1,min,R1,max]，其中，R1,min为信道资源集合A的容量的最小值，R1,max为信道资源集合A的容量的最大值，同理，信道资源集合B对应的容量范围为[R2,min,R2,max]，信道资源集合C对应的容量范围为[R3,min,R3,max]，信道资源集合D对应的容量范围为[R4,min,R4,max]。UCI的大小可以用UCI的比特数或UCI的数量衡量，具体地，上述4个容量范围均表示比特数范围，若UCI的比特数K满足R2,min≤K≤R2,max，即UCI的比特数在[R2,min,R2,max]范围内，则终端设备确定第一信道资源集合为信道资源集合B。
或者，接入网设备向终端设备发送配置信息，所述配置信息包括4个信道资源集合中每个信道资源集合对应的容量信息，且每个信道资源集合对应不同的容量信息，例如，信道资源集合A作为第1个信道资源集合对应的容量信息为R1，且信道资源集合A中每个信道资源分别对应的信道容量均为R1；信道资源集合B作为第2个信道资源集合对应的容量信息为R2，且信道资源集合B中每个信道资源分别对应的信道容量均为R2；信道资源集合C作为第3个信道资源集合对应的容量信息为R3，且信道资源集合C 中每个信道资源分别对应的信道容量均为R3；信道资源集合D作为第4个信道资源集合对应的容量信息为R4，且信道资源集合D中每个信道资源分别对应的信道容量均为R4；R1<R2<R3<R4，若所述UCI的比特数Ra满足Ri-1<Ra≤Ri,1≤i≤4，则所述终端设备确定第一信道资源集合为所述第i个信道资源集合，具体如，UCI的比特数Ra满足R1<Ra≤R2，则所述终端设备确定第一信道资源集合为第2个信道资源集合即信道资源集合B。
另外，若第一信道资源集合是信道资源集合A时，信道指示信息00指示信道资源1-1、信道指示信息01指示信道资源1-2、信道指示信息10指示信道资源1-3、信道指示信息11指示信道资源1-4；若第一信道资源集合是信道资源集合B时，信道指示信息00指示信道资源2-1、信道指示信息01指示信道资源2-2、信道指示信息10指示信道资源2-3、信道指示信息11指示信道资源2-4；若第一信道资源集合是信道资源集合C时，信道指示信息00指示信道资源3-1、信道指示信息01指示信道资源3-2、信道指示信息10指示信道资源3-3、信道指示信息11指示信道资源3-4；若第一信道资源集合是信道资源集合D时，信道指示信息00指示信道资源4-1、信道指示信息01指示信道资源4-2、信道指示信息10指示信道资源4-3、信道指示信息11指示信道资源4-4。
若第一信道资源集合是信道资源集合B，且信道指示信息携带的信道资源标识号为二进制数01，则终端设备按照信道指示信息从信道资源集合B中确定出的信道资源为信道资源2-2。若第一信道资源集合是信道资源集合D，终端设备按照同一信道指示信息从信道资源集合D中确定出的信道资源为信道资源4-2，即同一信道指示信息在不同子帧时刻可以指示不同的信道资源。
在本发明实施例中，所述N个信道资源集合中每个信道资源集合包括的信道资源的个数相同。如图2和图3所示，各信道资源集合包括的信道资源的个数相同，此外，各信道资源集合包括的信道资源的个数还可以不同。
所述N个信道资源集合中至少一个信道资源集合所包括的至少两个信道资源格式不同。一个信道资源集合中至少有两种不同格式的信道资源，例如信道资源集合A中4个信道资源可能有两种格式、三种格式或四 种格式。图17为本发明实施例提供的信道资源的格式的示意图。所述信道资源的格式可以是但不限于是以下格式：
第一种：物理上行控制信道(Physical Uplink Control Channel，简称PUCCH)格式3。将原始比特信道编码和调制后的符号，分别放到一个子帧的两个时隙中。这样，每个时隙上有12个调制符号，并且这12个调制符号放在一个时隙的一个时域符号上的12个连续子载波上，即占用一个资源块(Resource Block，简称RB)中的一个时域符号上的12个子载波。然后，针对每个时隙，在时域用序列w进行长度为5的正交掩码(Orthogonal Cover Code，简称OCC)扩频，一个时隙占一个RB内的5个时域符号，不同的UE可以在一个RB上通过不同的OCC进行码分复用，其余两个符号用来承载参考信号(Reference Signal，简称RS)。然后，对扩频后的进行离散傅里叶变换(Discrete Fourier Transform，简称DFT)预编码以及快速傅里叶逆变换(Inverse Fast Fourier Transform，IFFT)。Normal CP时，PUCCH format 3发送结构图如图17所示：1个资源块中参考信号具体为导频部分，除参考信号之外部分为数据部分。
第二种：基于PUCCH格式3的第一格式。将上述PUCCH格式3的信道资源扩展到占用N(N>1)个RB。以2个RB为例，把每个时隙占用的12个子载波扩展成每个时隙占用24个子载波。对原始比特信道编码和加扰后的比特调制，然后分别放到一个子帧中2个RB的各个子载波上，然后，针对每个时隙，在时域，用序列w进行长度为5的正交掩码(Orthogonal Cover Code，简称OCC)扩频，一个时隙占5个时域符号，其余两个符号用来承载参考信号(Reference Signal，简称RS)，解调参考信号的映射位置和PUCCH格式3相同。然后，在每个符号上对2个RB内扩频后的数据进行统一的长度为24的DFT预编码以及快速傅里叶逆变换(Inverse Fast Fourier Transform，简称IFFT)。扩展到3RB或更多RB的方案类似，只需要在频域进行扩展即可。在该格式中的原始比特信息除了使用RM编码外，还可以用卷积码编码的方式，例如咬尾卷积码(Tail Biting CC,简称TBCC)。
第三种：基于PUCCH格式3的第二格式。信道资源占用N(N>1)个RB，每个RB内的格式和上述PUCCH格式3相同。以2个RB为例，把每个 时隙占用的12个子载波扩展成每个时隙占用24个子载波。对原始比特信道编码和加扰后的比特调制，然后分别放到一个子帧中2个RB的各个子载波上，然后，针对每个时隙，在时域，用序列w进行长度为5的正交掩码(Orthogonal Cover Code，简称OCC)扩频，一个时隙占5个时域符号，其余两个符号用来承载参考信号(Reference Signal，简称RS)，解调参考信号的映射位置和PUCCH格式3相同。然后，在每个符号上对2个RB中的每个RB内扩频后的数据分别进行长度为12的DFT预编码。将各DFT预编码的结果映射到快速傅里叶逆变换IFFT的频域在载波上后完成IFFT变换。扩展到3RB或更多RB的方案类似，只需要在频域进行扩展即可。在该格式中的原始比特信息除了使用RM编码外，还可以用卷积码编码的方式，例如咬尾卷积码(Tail Biting CC,简称TBCC)。
第四种：基于PUCCH格式3的第三格式。信道资源占用N(N≥1)个RB。一种可能的方式是在信道资源中采用DFT-S-OFDM传输方式。对原始比特信道编码调制分别放到一个子帧的K个符号上。针对K个符号的每个符号，在时域，使用长度为M(M<5)的正交掩码OCC扩频，每个待发送的调制符号占M个时域符号，同时每个时隙有两个符号用来承载参考信号(Reference Signal，简称RS)。然后，解调参考信号的映射位置和PUCCH格式3相同。对扩频后的进行DFT预编码以及快速傅里叶逆变换(Inverse Fast Fourier Transform,简称IFFT)。另一种可能的方式是在N个RB的每个RB资源中采用DFT-S-OFDM传输方式。对原始比特信道编码调制分别放到一个子帧的K个符号上。针对K个符号的每个符号，在时域，使用长度为M(M<5)的正交掩码OCC扩频，每个待发送的调制符号占M个时域符号，同时每个时隙有两个符号用来承载参考信号(Reference Signal，简称RS)，解调参考信号的映射位置和PUCCH格式3相同。在该格式中的原始比特信息除了使用RM编码外，还可以用卷积码编码的方式，例如咬尾卷积码(Tail Biting CC,简称TBCC)。
第四种：基于PUCCH格式3的第四格式。信道资源占用N(N≥1)个RB。一种可能的方式是在信道资源中采用DFT-S-OFDM传输方式。对原始比特信道编码调制分别放到一个子帧的两个时隙中。每个符号可以放置P(P≥2)个编码调制符号，在时域，使用长度为5的P个正交掩码不同OCC 分别对每个符号上的P个编码调制符号扩频，并将P个扩频后的信号叠加。每个待发送的调制符号占5个时域符号，同时每个时隙有两个符号用来承载参考信号(Reference Signal，简称RS)，解调参考信号的映射位置和PUCCH格式3相同。然后，对扩频后的进行DFT预编码以及快速傅里叶逆变换(Inverse Fast Fourier Transform,简称IFFT)。另一种可能的方式是在N个RB的每个RB资源中采用DFT-S-OFDM传输方式。对原始比特信道编码调制分别放到一个子帧的两个时隙中。每个符号可以放置P(P≥2)个编码调制符号，在时域，使用长度为5的P个正交掩码不同OCC分别对每个符号上的P个编码调制符号扩频，并将P个扩频后的信号叠加。每个待发送的调制符号占5个时域符号，同时每个时隙有两个符号用来承载参考信号(Reference Signal，简称RS)，解调参考信号的映射位置和PUCCH格式3相同。在该格式中的原始比特信息除了使用RM编码外，还可以用卷积码编码的方式，例如咬尾卷积码(Tail Biting CC,简称TBCC)。
第五种：基于PUSCH的格式。信道资源占用N(N≥1)个RB。对每个PRB，在Normal CP的情况下，每个PRB的中间一个符号为解调参考信号；在Extended CP的情况下，每个PRB的第三个符号为解调参考信号。对原始待反馈信息进行信道编码和调制后映射到第一PUCCH信道资源除解调参考信号外的其他位置，然后进行DFT预编码以及快速傅里叶逆变换(Inverse Fast Fourier Transform，简称IFFT)。在该格式中的原始比特信息可以用卷积码编码的方式，例如咬尾卷积码(Tail Biting CC,简称TBCC)。Normal CP时，基于PUSCH的格式发送结构图如图17所示：1个资源块中参考信号具体为导频部分，除参考信号之外部分为数据部分。
所述N个信道资源集合中至少一个信道资源集合所包括的至少两个信道资源格式相同但信道容量不同。例如，信道资源集合A中信道资源1-1和信道资源1-2的格式相同但信道容量不同。
所述UCI还包括调度请求信息SR。
所述终端设备通过物理控制信道从接入网设备接收信道指示信息之前，还包括：所述终端设备通过高层信令从所述接入网设备接收所述N个信道资源集合的配置信息，且不同的所述终端设备对应的所述N个信道资源集合的配置信息不同。
在所述终端设备通过物理控制信道从接入网设备接收信道指示信息之前，所述终端设备接收所述接入网设备发送的配置信息，该配置信息包括所述N个信道资源集合，且不同的所述终端设备对应的所述N个信道资源集合的配置信息不同。
本发明实施例具体给出了终端设备根据UCI的大小，从至少两个信道资源集合中确定出与UCI的大小匹配的一个信道资源集合为第一信道资源集合的方法。
图4为本发明另一实施例提供的上行控制信息接收方法流程图。本发明实施例针对随着上行信道的数量不断增加，接入网设备下发的信道指示信息的比特数不断增加，导致下行信道资源消耗较大，提供了上行控制信息发送方法，该方法具体步骤如下：
步骤S401、接入网设备通过物理控制信道向终端设备发送信道指示信息；
本发明实施例涉及LTE系统中的接入网设备和终端设备，接入网设备具体为基站，接入网设备通过多个载波中的至少一个载波向同一终端设备发送下行数据，终端设备针对各载波上的下行数据分别进行确认并产生HARQ-ACK信息；另外，接入网设备分别通过各载波向该终端设备发送参考信号，终端设备通过检测各载波上的参考信号获得各载波对应的信道状态信息CSI，接入网设备通过上行信道向接入网设备反馈上行控制信息UCI，UCI包括HARQ-ACK信息和信道状态信息CSI中的至少一种。
在接入网设备通过上行信道向接入网设备反馈上行控制信息UCI之前，接入网设备通过物理控制信道向终端设备发送信道指示信息，物理控制信道具体为物理下行控制信道(Physical Downlink Control Channel，简称PDCCH)和增强的物理下行控制信道(Enhanced Physical Downlink Control Channel，简称EPDCCH)，且物理控制信道上承载的信息为动态配置的信息，即信道指示信息作为一种动态配置的信息承载在物理控制信道上，由接入网设备发送到终端设备。
步骤S402、所述接入网设备预先为所述终端设备配置N个信道资源集合，以使所述终端设备从N个信道资源集合中确定一个信道资源集合为第一信道资源集合，并确定所述第一信道资源集合中所述信道指示信息所指 示的信道资源，其中，N为大于或等于2的正整数，所述N个信道资源集合中每一个包括至少两个信道资源。
在本发明实施例中，可以先执行步骤S401后执行步骤S402，也可以先执行步骤S402后执行步骤S401，接入网设备预先为所述终端设备配置N个信道资源集合，N为大于或等于2的正整数，所述N个信道资源集合中每一个包括至少两个信道资源；终端设备从所述N个信道资源集合中确定一个信道资源集合为第一信道资源集合。，具体地，从N个信道资源集合中确定一个信道资源集合为第一信道资源集合可依据终端设备向接入网设备反馈的UCI的类型或大小，UCI的类型具体可通过UCI包括的具体内容加以区别，UCI的大小具体可通过UCI的比特数或UCI的数量加以衡量。确定出第一信道资源集合，然后所述终端设备确定所述第一信道资源集合中所述信道指示信息所指示的信道资源。具体地，所述信道指示信息指示的信道资源是所述第一信道资源集合中的信道资源。例如，第一信道资源集合包括信道资源a、信道资源b、信道资源c、信道资源d四个信道资源。预定义信道指示信息00指示信道资源a、信道指示信息01指示信道资源b、信道指示信息10指示信道资源c、信道指示信息11指示信道资源d。通过信道指示信息的指示便可以从第一信道资源集合中确定出所述信道资源。
步骤S403、所述接入网设备接收所述终端设备在所述信道资源上发送的上行控制信息UCI。
接入网设备接收终端设备通过确定的信道资源发送的上行控制信息UCI，即信道资源作为上行信道承载上行控制信息UCI。
本发明实施例通过接入网设备向终端设备发送包括至少两个信道资源集合的配置信息，每个信道资源集合包括至少两个信道资源，相当于将接入网设备分配给终端设备的所有信道资源进行分组，每组相当于一个信道资源集合，终端设备先从多个信道资源集合中确定出第一信道资源集合，再依据信道指示信息从第一信道资源集合中确定信道资源，根据同一信道指示信息在不同子帧时刻可以确定出不同的信道资源，而现有技术同一信道指示信息在不同子帧时刻只能确定一个信道资源，随着信道资源的数量不断增加，本发明实施例中信道指示信息需要增加的比特数小于现有 技术中信道指示信息需要增加的比特数，减少了信道指示信息在下发过程中对下行信道资源的消耗。
在上述实施例的基础上，所述N个信道资源集合中每个信道资源集合包括的信道资源的个数相同。如图2和图3所示，各信道资源集合包括的信道资源的个数相同，此外，各信道资源集合包括的信道资源的个数还可以不同。
所述N个信道资源集合中至少一个信道资源集合所包括的至少两个信道资源格式不同。一个信道资源集合中至少有两种不同格式的信道资源，例如信道资源集合A中4个信道资源可能有两种格式、三种格式或四种格式。所述信道资源的格式如图17所示，以及上述实施例详述的五种格式，此处不再赘述。
所述N个信道资源集合中至少一个信道资源集合所包括的至少两个信道资源格式相同但信道容量不同。例如，信道资源集合A中信道资源1-1和信道资源1-2的格式相同但信道容量不同。
所述UCI还包括调度请求信息SR。
所述接入网设备通过物理控制信道向终端设备发送信道指示信息之前，还包括：所述接入网设备通过高层信令向所述终端设备发送所述N个信道资源集合的配置信息，且不同的所述终端设备对应的所述N个信道资源集合的配置信息不同。
在所述接入网设备通过物理控制信道向终端设备发送信道指示信息之前，所述接入网设备向所述终端设备发送配置信息，该配置信息包括所述N个信道资源集合，且不同的所述终端设备对应的所述N个信道资源集合的配置信息不同。
本发明实施例具体给出了终端设备根据UCI的类型或UCI的大小从多个信道资源集合中确定出与UCI的类型或UCI的大小匹配的一个信道资源集合为第一信道资源集合的方法。
图5为本发明另一实施例提供的上行控制信息发送方法流程图。本发明实施例针对接入网设备通过信道指示信息为该终端设备指定的上行信道的容量并不符合UCI的大小，导致上行信道的利用率较低或UCI比特丢失，提供了上行控制信息发送方法，该方法具体步骤如下：
步骤S501、终端设备通过物理控制信道从接入网设备接收信道指示信息；
终端设备通过物理控制信道接收接入网设备发送的信道指示信息，物理控制信道具体为物理下行控制信道(Physical Downlink Control Channel，简称PDCCH)和增强的物理下行控制信道(Enhanced Physical Downlink Control Channel，简称EPDCCH)，且物理控制信道上承载的信息为动态配置的信息，即信道指示信息作为一种动态配置的信息承载在物理控制信道上，由接入网设备发送到终端设备，信道指示信息具体为信道指示信息。
步骤S502、所述终端设备依据所述信道指示信息从N个信道资源中确定第一信道资源，其中，N为大于或等于2的正整数，所述N个信道资源为所述接入网设备预先为所述终端设备配置的；
若接入网设备分配给终端设备四个信道资源，具体为信道资源a、信道资源b、信道资源c、信道资源d。预定义信道指示信息00指示信道资源a、信道指示信息01指示信道资源b、信道指示信息10指示信道资源c、信道指示信息11指示信道资源d。则可以通过信道指示信息的指示从所述的四个信道资源中确定第一信道资源，例如通过信道指示信息的指示确定第一信道资源为信道资源b。
步骤S503、所述终端设备增大或减小所述第一信道资源得到第二信道资源；
所述N个信道资源中每个信道资源对应不同的信道容量；所述终端设备增大或减小所述第一信道资源得到第二信道资源之前，还包括：所述终端设备确定所述UCI的大小；所述终端设备增大或减小所述第一信道资源得到第二信道资源，包括：若所述第一信道资源对应的信道容量大于所述UCI的大小，则所述终端设备减小所述第一信道资源得到第二信道资源；若所述第一信道资源对应的信道容量小于所述UCI的大小，则所述终端设备增大所述第一信道资源得到第二信道资源。
步骤S504、所述终端设备在所述第二信道资源上向所述接入网设备发送上行控制信息UCI。
通过步骤S503修改所述第一信道资源得到第二信道资源，使第二信 道资源对应的容量与上行控制信息UCI的大小相匹配，终端设备通过所述第二信道资源向所述接入网设备发送所述UCI。
本发明实施例通过信道指示信息确定至少两个信道资源中的一个信道资源为第一信道资源，依据第一信道资源对应的容量信息和终端设备生成的上行控制信息UCI的大小增大或减小第一信道资源得到第二信道资源，终端设备通过第二信道资源向接入网设备发送UCI，以使第二信道资源对应的容量与UCI的大小相匹配，即当第一信道资源大于上行控制信息UCI的大小时，通过减小第一信道资源增加了上行信道的利用率，当第一信道资源小于上行控制信息UCI的大小时，通过增大第一信道资源防止UCI比特被丢弃。
图6为本发明另一实施例提供的信道资源的示意图；图7为本发明另一实施例提供的信道资源的示意图。在上述实施例的基础上，所述终端设备减小所述第一信道资源得到第二信道资源包括：所述终端设备将所述第一信道资源的信道容量减小k个基础信道单元得到第二信道资源，以使所述UCI的大小Ra满足Rb-(k+1)R0<Ra≤Rb-kR0，其中，Rb表示所述第一信道资源的信道容量，R0表示所述基础信道单元的大小。
在本发明实施例中，第一信道资源的信道容量表示为Rb，UCI的大小表示为Ra，例如，在子帧n时刻，终端设备通过信道指示信息确定的第一信道资源对应的容量大于UCI的大小，即Rb>Ra，则减小第一信道资源的信道容量，具体地，第一信道资源的信道容量以基础信道单元为单位，预设基础信道单元的大小为R0，依据Rb与Ra的差值，将该差值除以R0，并向上取整便可获得需要减少的基础信道单元的个数k，以使所述UCI的大小Ra满足Rb-(k+1)R0<Ra≤Rb-kR0。由于不同子帧，UCI的大小不同，则同样大小的第一信道资源在不同子帧需要减少的大小不同，例如子帧n时刻第一信道资源需要减小4个基础信道单元，子帧m时刻第一信道资源需要减小7个基础信道单元。
所述k个基础信道单元中频率最高的子载波与所述第一信道资源中频率最低的子载波相邻；或者所述k个基础信道单元中频率最低的子载波与所述第一信道资源中频率最高的子载波相邻。
如图6所示，沿着箭头f的方向频率增大，具体地，k个基础信道单 元中频率最高的子载波与所述第一信道资源中频率最低的子载波相邻，即可以从第一信道资源的低频段减小第一信道资源。
如图7所示，沿着箭头f的方向频率增大，具体地，k个基础信道单元中频率最低的子载波与所述第一信道资源中频率最高的子载波相邻，即可以从第一信道资源的高频段减小第一信道资源。
图8为本发明另一实施例提供的信道资源的示意图；图9为本发明另一实施例提供的信道资源的示意图。在上述实施例的基础上，所述终端设备增大所述第一信道资源得到第二信道资源包括：所述终端设备将所述第一信道资源的信道容量增加k个基础信道单元，以使所述UCI的大小Ra满足Rb+(k-1)R0<Ra≤Rb+kR0，其中，Rb表示所述第一信道资源的信道容量，R0表示所述基础信道单元的大小。
在本发明实施例中，第一信道资源的信道容量表示为Rb，UCI的大小表示为Ra，例如，在子帧n时刻，终端设备通过信道指示信息确定的第一信道资源对应的容量小于UCI的大小，即Rb<Ra，则增大第一信道资源的信道容量，具体地，第一信道资源的信道容量以基础信道单元为单位，预设基础信道单元的大小为R0，依据Ra与Rb的差值，将该差值除以R0，并向上取整便可获得需要增加的基础信道单元的个数k，以使所述UCI的大小Ra满足Rb+(k-1)R0<Ra≤Rb+kR0。由于不同子帧，UCI的大小不同，则同样大小的第一信道资源在不同子帧需要增加的大小不同，例如子帧n时刻第一信道资源需要增加4个基础信道单元，子帧m时刻第一信道资源需要增加7个基础信道单元。
所述k个基础信道单元中频率最高的子载波与所述第一信道资源中频率最低的子载波相邻；或者所述k个基础信道单元中频率最低的子载波与所述第一信道资源中频率最高的子载波相邻。
如图8所示，沿着箭头f的方向频率增大，具体地，k个基础信道单元中频率最高的子载波与所述第一信道资源中频率最低的子载波相邻，即可以从第一信道资源的低频段增大第一信道资源。
如图9所示，沿着箭头f的方向频率增大，具体地，k个基础信道单元中频率最低的子载波与所述第一信道资源中频率最高的子载波相邻，即可以从第一信道资源的高频段增大第一信道资源。
在本发明实施例中，所述UCI包括所述终端设备对接收到的下行数据的HARQ-ACK信息和所述终端设备生成的信道状态信息CSI中的至少一种。
所述UCI还包括调度请求信息SR。
所述终端设备通过物理控制信道从接入网设备接收信道指示信息之前，还包括：所述终端设备通过高层信令从所述接入网设备接收所述N个信道资源的配置信息，且不同的所述终端设备对应的所述N个信道资源集合的配置信息不同。
在所述终端设备通过物理控制信道从接入网设备接收信道指示信息之前，所述终端设备还接收所述接入网设备通过高层信令发送的配置信息，该配置信息包括所述N个信道资源，且不同的所述终端设备对应的所述N个信道资源集合的配置信息不同。
本发明实施例以基础信道单元为单位增大或减小第一信道资源得到第二信道资源，以使第二信道资源对应的容量与UCI的大小相匹配，即当第一信道资源大于上行控制信息UCI的大小时，通过减小第一信道资源增加了上行信道的利用率，当第一信道资源小于上行控制信息UCI的大小时，通过增大第一信道资源防止UCI比特被丢弃。
图10为本发明另一实施例提供的上行控制信息接收方法流程图。本发明实施例针对接入网设备通过信道指示信息为该终端设备指定的上行信道的容量并不符合UCI的大小，导致上行信道的利用率较低或UCI比特被丢弃，提供了上行控制信息发送方法，该方法具体步骤如下：
步骤S1001、接入网设备通过物理控制信道向终端设备发送信道指示信息，以使所述终端设备依据所述信道指示信息从N个信道资源中确定第一信道资源，并增大或减小所述第一信道资源得到第二信道资源，其中，N为大于或等于2的正整数，所述N个信道资源为所述接入网设备预先为所述终端设备配置的；
终端设备通过物理控制信道接收接入网设备发送的信道指示信息，物理控制信道具体为物理下行控制信道(Physical Downlink Control Channel，简称PDCCH)和增强的物理下行控制信道(Enhanced Physical Downlink Control Channel，简称EPDCCH)，且物理控制信道上承载的信息为动态配置的信息，即信道指示信息作为一种动态配置的信息承载在物 理控制信道上，由接入网设备发送到终端设备，信道指示信息具体为信道指示信息。若接入网设备分配给终端设备四个信道资源，具体为信道资源a、信道资源b、信道资源c、信道资源d。预定义信道指示信息00指示信道资源a、信道指示信息01指示信道资源b、信道指示信息10指示信道资源c、信道指示信息11指示信道资源d。则可以通过信道指示信息的指示从所述的四个信道资源中确定第一信道资源，例如通过信道指示信息的指示确定第一信道资源为信道资源b。所述N个信道资源中每个信道资源对应不同的信道容量；所述终端设备增大或减小所述第一信道资源得到第二信道资源之前，还包括：所述终端设备确定所述UCI的大小；所述终端设备增大或减小所述第一信道资源得到第二信道资源，包括：若所述第一信道资源对应的信道容量大于所述UCI的大小，则所述终端设备减小所述第一信道资源得到第二信道资源；若所述第一信道资源对应的信道容量小于所述UCI的大小，则所述终端设备增大所述第一信道资源得到第二信道资源。
步骤S1002、所述接入网设备接收所述终端设备在所述第二信道资源上发送的上行控制信息UCI。
