Description

一种上行控制信息的发送方法、接收方法及相关装置 技术领域
本发明涉及通信领域,特别是一种上行控制信息的发送方法、接收方法及相关装置。
背景技术
长期演进(Long Term Evolution,英文缩写:LTE)系统中业务的传输是基于基站(eNodeB,英文缩写:eNB)调度的,调度的基本时间单位是一个子帧,一个子帧包括多个时域符号。具体的调度流程是基站在控制信道发送控制信息,比如物理下行控制信道(Physical Downlink Control Channel,英文缩写:PDCCH)或增强的物理下行控制信道(Enhanced Physical Downlink Control Channel,英文缩写:EPDCCH),该控制信道可以承载物理下行共享信道(Physical Downlink Shared Channel,英文缩写:PDSCH)或物理上行控制信道(Physical Uplink Control Channel,英文缩写:PUSCH)的调度信息,该调度信息包括资源分配信息以及调整编码方式等控制信息。用于设备(User Equipment,英文缩写:UE)在子帧中检测控制信道,并根据检测出的控制信道中承载的调度信息来进行下行数据信道的接收或上行数据信道的发送。
LTE支持CA技术,即基站把多个载波配置给一个UE来提升UE的数据速率。为使eNodeB可以在多个下行载波上对UE调度并发送下行数据,UE需要通过PUCCH资源或PUSCH资源向eNB反馈各载波上信道状态信息(Channel State Information,英文缩写:CSI)。由于上行控制信道的格式显示,一般的,UE只反馈某一个载波上具有最高优先级的周期CSI,对于具有相同优先级的多个下行载波的周期CSI,反馈下行分载波索引最小的载波的周期CSI。在一个特定的上行子帧,该上行子帧被eNB配置需要反馈调度请求(Scheduling Request,英文缩写:SR),用于向eNB请求上行上行共享信道(Uplink Share Channel,英文缩写:UL-SCH)资源。
在现有技术中,在预配置UE不支持PUCCH和PUSCH同时发送,或者预配置UE支持PUCCH和PUSCH同时发送但是在没有PUSCH调度的情况下,如果需要在同一个子帧同时发送周期CSI和SR,或者需要在同一个子帧 发送多个载波中主载波的HARQ-ACK反馈信息或者所述多个载波中不大于预设数目载波的HARQ-ACK反馈信息,则丢弃周期CSI的发送。这样,当eNB所配置的载波数较多时,会导致丢弃大量周期CSI信息的信息将造成大量载波上周期CSI信息的缺失,影响eNB对UE的调度准确性。

具体实施方式
LTE系统中,传输信号的资源块(resource block,RB)包括时域资源和频域资源。时域资源的最小单位为正交频分复用(orthogonal frequency division multiplexing,OFDM)符号,频域资源的最小单位为子载波。当前LTE系统中,一个资源块在频域上包括12个子载波。本发明实施例中所述的时域符号可以是LTE系统中的OFDM符号,但是并不限于此,例如还可以是其他系统 中的时域上的符号或者其他形式的时域上的最小单位。
LTE定义了几种不同的PUCCH格式(如表1所示)。
表1:PUCCH格式简介
Figure PCTCN2015087053-appb-000001
PUCCH格式format 1携带SR信息。UE只有在请求上行资源时,才需要发送SR;其它时候UE不发送SR以节约电量和减少干扰。因此与HARQ-ACK信息不同,HARQ-ACK是发送ACK或NACK,而SR是发或不发。基站在检测HARQ-ACK时要做状态检测,即一般要检测出是ACK状态或是NACK状态,而检测SR是通过对应的SR的PUCCH资源上是否存在能量来表示是否存在SR。。
PUCCH format 1a中,传输1比特bit的混合自动重传请求确认(Hybrid Automatic Repeat Request–ACKnowledge,英文缩写:HARQ-ACK)信息,使用二进制相移键控(Binary Phase Shift Keying,英文缩写:BPSK)调制,对应单小区、单codeword的场景。如果同时需要发送SR,还可以携带SR信息。
PUCCH format 1b中,传输2bit的HARQ-ACK信息,使用四相移键控 (Quadrature Phase Shift Keying,英文缩写:QPSK)调制,对应单小区、双codeword的场景。如果同时需要发送SR,还可以携带SR信息。
PUCCH format 2中,对于标准循环前缀(Normal Cyclic Prefix,Normal CP)而言,只携带20bit的CSI信息;对于扩展CP(Extended CP)而言,不仅携带20bit的CSI信息,还携带1bit或2bit的确认(ACKnowledge,英文缩写:ACK)/不确认(NACKnowledge,英文缩写:NACK)信息,二者均采用QPSK调制。PUCCH格式2的信道结构为:在Normal CP下用于传输PUCCH格式2的RB,其每个位置slot的第2和第6个符号symbol用于传输解调的参考信号(Demodulation-Reference Symbol,英文缩写:DM-RS),而剩余的5个symbol用于传输PUCCH;而在Extended CP下,每个slot只有6个symbol,此时只有1个symbol用于传输DM-RS(第4个symbol),而剩余的5个symbol用于传输PUCCH。配给UE的信道质量信息(Channel Quality Indicator,英文缩写:CQI)资源是通过CQI周期配置“CQI-ReportPeriodic”消息中的PUCCH中CQI的资源索引信元“cqi-PUCCH-ResourceIndex”段配置的。
PUCCH format 2a中,携带20bit的CSI信息(QPSK调制)和1bit的ACK/NACK信息(对应单小区、单codeword的场景,使用BPSK调制)。
PUCCH format 2b中,携带20bit的CSI信息(QPSK调制)和2bit的ACK/NACK信息(对应单小区、双codeword的场景,使用QPSK调制)。
PUCCH format 2a/2b中,只支持Normal CP。
PUCCH format 3中,可支持至多5个serving cell且UE在每个serving cell都配置了MIMO的场景下的HARQ-ACK发送。在同时有SR需要传输时,也可以支持传输HARQ-ACK的同时传输SR。并且在容量允许的情况下传输最多一个载波的CSI信息。PUCCH格式3的信道结构下图所示。具体的,对原始比特如20比特,进行里德穆勒(Reed Muller,RM)信道编码后生成48个比特,对编码后的比特进行加扰,将加扰后的比特调制成24个正交相移键控(quadrature phase shift keying,QPSK)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QPSK符号,并且这12个QPSK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,英文缩写: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,英文缩写: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,英文缩写:RS)。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,英文缩写:IFFT)。
随着LTE技术的继续演进,将来有可能需要支持更多比特数的HARQ-ACK反馈,比如大于20比特。例如,引入了更多载波的容量配置(Capacity Allocation,英文缩写:CA),比如10载波的CA。这样以10个时分双工(Time Division Duplex,英文缩写:TDD)上下行配置2的载波进行CA为例,就需要反馈40比特的HARQ-ACK。又如,虽然还是支持最多5载波的CA,但其中多个载波都配置成TDD上下行配置5,例如,主载波是上下行配置2,4个辅载波都是上下行配置5,那么需要反馈4+9*4=40比特的HARQ-ACK。为了支持大于20比特的HARQ-ACK传输,可能的方式是引入可支持更多比特传输的PUCCH格式,例如一种新PUCCH格式,该新PUCCH格式可以是新PUCCH格式一(该新PUCCH格式一可以是基于PUCCH format3的格式1(PUCCH format 3-based format 1))、新PUCCH格式二(该新PUCCH格式二可以是基于PUCCH format 3的格式2(PUCCH format 3-based format 2))、新PUCCH格式三(该新PUCCH格式三可以是基于PUCCH format 3的格式3(PUCCH format 3-based format 3))、新PUCCH格式四(该新PUCCH格式四可以是基于PUCCH format 3的格式4(PUCCH format 3-based format 4))、新PUCCH格式五(该新PUCCH格式五可以是基于PUCCH format 3的格式5(PUCCH format 3-based format 5))、新PUCCH格式六(该新PUCCH格式六可以是基于PUSCH format的格式1(PUSCH format-based format 1))中的任意一种,并且其中不同类型的上行控制信息(Uplink Control Information,英文缩写:UCI)信息可以使用相同或者不同的信道编码方式或者编码速率。所述新PUCCH格式的各种形式具体如下:
1、新PUCCH格式一
参照图19所示,DFT改为离散傅里叶变换,IFFT改为傅里叶反变换,w0~w4分别是正交掩码第一为到正交掩码第五位,RS为参考信号。使用 PUCCH format 3的信道结构,如信息编码调制符号的资源映射方式和解调参考信号的映射方式与PUCCH format 3的相同。不同的是,新PUCCH格式一中的原始比特信息是不包括HARQ-ACK的上行控制信息,如新PUCCH格式一仅用于传输CSI,或新PUCCH格式一用于传输CSI和SR。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,英文缩写:TBCC)。调制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,英文缩写:RB)中的一个时域符号上的12个子载波。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,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,其余两个时域符号用来承载参考信号(reference signal,英文缩写:RS)。然后,对扩频后的进行DFT以及快速傅里叶逆变换(inverse fast Fourier transform,英文缩写:IFFT)。
2、新PUCCH格式二
参照图20所示。新格式二的信道资源占用N(N>1)个RB,在每个时域符号上对N个RB内的扩频数据进行长度为N×12的DFT。以2个RB为例,每个时隙占用24个子载波。将调制符号分别放到一个子帧中2个RB的各个子载波上。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,OCC)扩频,一个时隙占5个时域符号,其余两个时域符号用来承载参考信号RS,解调参考信号的映射位置和PUCCH format 3相同。然后,在每个时域符号上对2个RB内扩频后的数据进行长度为24的DFT。扩展到3个RB或更多个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TBCC。
3、新PUCCH格式三
参照图21所示。信道资源占用N(N>1)个RB,在每个时域符号上对每个RB内的扩频数据分别进行长度为12的DFT。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OCC扩频,一个时隙占5个时域符号,其余两个时域符号用来承载RS,解调参考信号的映射位置和PUCCH format 3相同。然后,在每个时域符号上对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。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TBCC。

参照图7所示,对本发明实施例中上行控制信息的发送方法的一个实施例包括:
101、用户设备UE确定上行子帧中待发送的上行控制信息包括信道状态信息CSI,所述CSI为基站eNB为所述UE配置的多个载波中的至少一个载波 的CSI;
为了提高eNB与UE的数据传输效率,eNB一般会给UE配置多个载波,每个载波中的信道状态信息CSI包括信道质量指示(Channel Quality Indicator,英文缩写:CQI)、秩指示(rank indication,英文缩写:RI)、预编码矩阵指示(Precoding Matrix Indicator,英文缩写:PMI)、预编码类型指示(Precoding TypeIndicator,英文缩写:PTI)等信息。CQI用来反映下行PDSCH的信道质量。RI用来指示PDSCH的有效的数据层数。PMI用来指示码本集合的索引。PMI用来指示预编码类型的索引。eNB会需要获取每个载波的信道状态信息CSI,以使得eNB根据每个载波的CSI来调整通过该载波发送数据的调度结果,以提高下行数据传输效率。eNB与UE之间传输数据的最小单位是子帧,UE向eNB发送数据的子帧为上行子帧,所述上行子帧承载UE需要向eNB发送的上行控制信息,由于每个载波的CSI并不是UE与eNB每次进行数据交互均要发送的,所以UE需要确定所述上行子帧中待发送的上行控制信息包括CSI。
102、所述UE确定所述上行子帧中待发送的上行控制信息包括SR;
所述UE需要在用于发送调度请求SR状态的子帧将表示所述UE是否有上行数据调度请求的信息发送给所述eNB。当所述UE有上行数据调度请求时,会通过上行子帧发送表示有数据调度请求的SR给所述eNB;当所述UE没有上行数据调度请求时,会通过上行子帧发送表示没有数据调度请求的SR给所述eNB;所述UE确定用于发送调度请求SR状态的上行子帧通过eNB向所述UE发送的参数sr-PUCCH-ResourceIndex确定。所述UE可通过该参数获取发送调度请求SR的周期SRPERIODICITY、和在该周期内的子帧偏移NOFFSET,SR。所述UE通过预设规则确定所述上行子帧是否满足发送调度请求SR状态的子帧的条件,从而确定所述上行子帧中待发送的上行控制信息是否包括SR。
具体的,所述UE通过预设规则确定所述上行子帧是否满足发送调度请求SR状态的子帧的条件,所述预设规则为
Figure PCTCN2015087053-appb-000002
其中nf为系统帧号;ns为子帧n内的slot在系统帧内的编号,SRPERIODICITY为SR的发送周期、NOFFSET,SR为SR在该周期内的子帧偏移,SRPERIODICITY和NOFFSET,SR由所述eNB为UE配置的SR的参数sr-PUCCH-ResourceIndex确定。如果所述子帧n满足上述条件,则所述上 行子帧中待发送的上行控制信息包括SR;如果所述子帧n不满足上述条件,则所述上行子帧中待发送的上行控制信息不包括SR。需要说明的是,步骤101与步骤102的先后顺序不做限定。
103、所述UE为所述CSI确定第一上行信道资源,所述第一上行信道资源为所述eNB为所述UE配置的用于发送CSI的资源;
所述eNB为所述UE配置的用于发送CSI的资源包括PUCCH资源或者PUSCH资源。所述eNB为所述UE与配置用于发送CSI的PUCCH资源可以是一个或者多个,所述配置的用于发送CSI的多个PUCCH资源可以有不同的格式。所述UE需要在配置的多个用于发送CSI的PUCCH资源中确定一个PUCCH资源为第一上行信道资源;或者,所述UE确定所述eNB调度在所述上行子帧发送的PUSCH的资源为第一上行信道资源。
104、所述UE在所述上行子帧的所述第一上行信道资源上发送所述CSI以及SR;
所述UE通过步骤101和步骤102确定上行子帧中待发送的上行控制信息包括信道状态信息CSI以及SR,并通过步骤103确定第一上行信道资源后,则所述UE在所述上行子帧的第一上行信道资源上发送所述CSI和SR,所述SR为表示所述UE有上行数据调度请求的信息或者表示所述UE没有上行数据调度请求的信息。
本发明实施例中,UE确定上行子帧中待发送的上行控制信息包括信道状态信息CSI以及SR,则所述UE确定用于发送所述CSI的第一上行信道资源,所述第一上行信道资源为具有固定位置的资源用于发送SR的格式的用于发送CSI的信道资源,那么,所述UE则能够在所述上行子帧的所述第一上行信道资源上发送所述CSI以及SR。这样,使得所述UE在所述上行子帧的第一上行信道资源上发送CSI以及SR,既保证了eNB能够获取UE的调度请求SR,又能够准确地获取每个载波的CSI,提高了eNB对UE资源调度的准确性。
上述实施例描述了UE在上行子帧的第一上行信道资源上发送所述CSI以及SR,在实际应用中,所述CSI包括周期CSI以及非周期CSI,所述第一上行信道资源包括PUCCH资源以及PUSCH资源,当所述CSI为周期CSI时,所述第一上行信道资源为PUCCH资源;当所述CSI为非周期CSI时,所述第 一上行信道资源为PUSCH资源。下面对当所述CSI为周期CSI时进行具体描述,参照图8所示,本发明实施例中上行控制信息的发送方法的另一实施例包括:
201、用户设备UE确定上行子帧中待发送的上行控制信息包括信道状态信息周期CSI,所述周期CSI为基站eNB为所述UE配置的多个载波中的至少一个载波的周期CSI;
UE向eNB发送的CSI信息分为周期性CSI和非周期的CSI信息。对于每一个下行载波,基站向配置UE每个下行载波的周期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,可以确定出需要发送每个下行载波的周期CSI的各上行子帧。
所述用户设备UE确定上行子帧中待发送的上行控制信息包括信道状态信息周期CSI。具体为,所述UE通过预先获取的所述基站向所述UE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判断在所述上行子帧是否需要发送周期CSI,根据判断结果,所述UE确定在所述的上行子帧需要发送所述基站eNB为所述UE配置的多个载波中的至少一个载波的周期CSI。
202、所述UE确定所述上行子帧中待发送的上行控制信息包括SR;
详细内容参照S102所述。需要说明的是,步骤201与步骤202的先后顺序此处不做限定。
203、所述UE为所述CSI确定第一上行信道资源,所述第一上行信道资源为PUCCH资源,所述PUCCH资源为所述eNB为所述UE配置的用于发送周期CSI的资源,所述PUCCH资源为具有第一PUCCH格式的资源;
具体的,所述第一PUCCH格式可以是上述新PUCCH格式一至新PUCCH格式六中的任意一种。
所述第一PUCCH格式具体为:所述第一PUCCH格式的容量大于预设比特数目,所述预设比特数目为11。其中,所述容量指的是在所述信道资源上可以发送的上行控制信息的最大比特数。所述预设比特为第二PUCCH格式的容量。所述第二PUCCH格式指的是容量为11比特的PUCCH格式2,所述PUCCH格式2具体为:对于标准Normal循环前缀(Cyclic Prefix,英文缩写 CP)而言,只携带20bit的CSI信息;对于Extended CP而言,不仅携带20bit的CSI信息,还携带1bit或2bit的确认(ACKnowledge,英文缩写:ACK)/不确认(NACKnowledge,英文缩写:NACK)信息,二者均采用QPSK调制。PUCCH格式2的信道结构为:在Normal CP下用于传输PUCCH格式2的RB,其每个位置slot的第2和第6个符号symbol用于传输解调的参考信号(Demodulation-Reference Symbol,英文缩写:DM-RS),而剩余的5个symbol用于传输PUCCH;而在Extended CP下,每个slot只有6个symbol,此时只有1个symbol用于传输DM-RS(第4个symbol),而剩余的5个symbol用于传输PUCCH。配给UE的信道质量信息(Channel Quality Indicator,英文缩写:CQI)资源是通过CQI周期配置“CQI-ReportPeriodic”消息中的PUCCH中CQI的资源索引信元“cqi-PUCCH-ResourceIndex”段配置的。
所述第一PUCCH格式还可以具体为:第一PUCCH格式采用卷积码编码。在具有第一PUCCH格式的PUCCH资源中可以发送的上行控制信息的比特数比在具有第二PUCCH格式的PUCCH资源中可以发送的上行控制信息的比特数更多。对于在具有第一PUCCH格式的PUCCH中可以发送的上行控制信息的比特数来说,采用卷积编码可以获得比里德穆勒(Reed Muller,英文缩写:RM)编码方式更高的编码增益。
所述具有第一PUCCH格式的PUCCH资源被配置为用于发送CSI的资源,且在上行子帧中待发送的上行控制信息包括SR时,其中固定位置的资源用于发送所述SR。
所述UE使用所述第一PUCCH格式在所述上行子帧的所述PUCCH资源上发送所述CSI以及所述SR,所述PUCCH资源中固定位置的资源为以下一种:
所述PUCCH资源中在目标时刻前任意位置的一个比特位的资源,所述目标时刻为对待发送的上行控制信息进行编码的时刻;可选的,所述PUCCH资源中在目标时刻前的第一个比特位的资源;或者,
所述PUCCH资源中在目标时刻前用于循环冗余校验码CRC校验编码的CRC比特位的资源,所述目标时刻为对待发送的上行控制信息进行编码的时刻;或者,
所述PUCCH资源中预设位置的资源单元;或者,
所述PUCCH资源中预设的用于承载参考信号的资源单元。
具体的,所述PUCCH资源中固定位置的资源为所述PUCCH资源中在目标时刻前任意位置的一个比特位的资源,所述目标时刻为对待发送的上行控制信息进行编码的时刻,可选的,所述PUCCH资源中在目标时刻前的第一个比特位的资源。上行控制信息在PUCCH资源中发送前,首先经过信道编码,然后对编码后的数据调制后发送。在所述PUCCH资源中发送所述CSI以及所述SR时,将所述UE有上行数据调度请求或者没有上行数据调度请求的信息和所述CSI的信息级联,首先经过信道编码,然后对编码后的数据调制后发送。所述PUCCH资源中固定位置的资源为所述PUCCH资源中在目标时刻前任意位置的一个比特位的资源指的是所述SR信息和所述CSI信息在信息在级联时,其中一个固定的位置用于SR的信息。例如,固定的位置为第一个比特的信息。
具体的,所述PUCCH资源中固定位置的资源为所述PUCCH资源中在目标时刻前用于CRC校验编码的CRC比特位,所述目标时刻为对待发送的上行控制信息进行编码的时刻。上行控制信息在PUCCH资源中发送前,首先经过信道编码,然后对编码后的数据调制后发送。在对所述上行控制信息信道编码前,需要对上行控制信息首先加入循环冗余校验码(Cyclic Redundancy Check,英文缩写:CRC),然后对上行控制信息和CRC的信息一起做信道编码。所述PUCCH资源中固定位置的资源为所述PUCCH资源中在目标时刻前用于CRC校验编码的CRC比特位的资源,指的是首先对所述CSI信息加入CRC校验码,然后将CRC校验码的资源用于发送所述SR,即CRC校验码的资源既用于所述CRC信息又用于发送所述SR。所述SR信息可以通过和所述CRC校验码做异或运算的扰码方式在所述固定位置的资源上发送。
具体的,所述PUCCH资源中固定位置的资源为所述PUCCH资源中预设位置的资源单元。上行控制信息在PUCCH资源中发送前,首先经过信道编码,然后对编码后的数据调制后发送。对于编码后的调制符号,采用预定义的规则映射到所述PUCCH资源的资源单元上。所述PUCCH资源中预设的时频位置的资源单元指的是在所述PUCCH资源的任意特定的资源单元上用于发送所述 SR。例如预定义所述PUCCH资源中时域的第三个符号中频率最低的六个资源单元用于映射所述SR。
具体的,所述PUCCH资源中固定位置的资源为所述PUCCH资源中预设的用于承载参考信号的资源单元。上行控制信息在PUCCH资源中发送的同时,需要在PUCCH资源中预设的用于发送参考信号的资源单元发送用于解调所述上行控制信息的参考信号。可以在所述预设用于承载参考信号的资源上发送所述SR。所述参考信号为恒包络零自相关(Constant Amplitude Zero Auto Correlation,英文缩写:CAZAC)序列。可以通过所述参考信号的序列发送所述SR。例如当所述SR为所述UE有上行数据调度请求时,在所述PUCCH资源中预设的参考信号的资源单元上发送第一参考信号序列。当所述SR为所述UE没有上行数据调度请求时,在所述PUCCH资源中预设的参考信号的资源单元上发送第二参考信号序列。即通过所述PUCCH资源中预设的参考信号的资源单元上发送的参考信号序列用于解调所述PUCCH资源中上行控制信息,同时通过所述参考信号序列是第一参考信号序列还是第二参考信号序列发送所述SR的信息。可选地,所述SR信息也可以通过和参考信号的序列做异或运算的扰码方式在所述固定位置的资源上发送。
204、当所述UE确定被所述eNB配置不允许同时发送PUCCH和PUSCH,或者所述UE确定被所述eNB配置允许同时发送PUCCH和PUSCH且所述UE确定在所述上行子帧上没有PUSCH发送时,所述UE使用所述第一PUCCH格式在所述上行子帧的所述PUCCH资源上发送所述CSI以及所述SR;
所述UE用所述第一PUCCH格式在所述上行子帧的所述PUCCH资源上发送所述CSI以及所述SR之前,需要确定所述UE被所述eNB配置为允许同时发送PUCCH和PUSCH还是不允许同时发送PUCCH和PUSCH。如果所述UE被所述eNB配置允许同时发送PUCCH和PUSCH且同时在所述上行子帧上有PUSCH发送,所述UE可以在所述待发送的PUSCH中发送所述CSI,并且同时在所述eNB为所述UE配置的用于发送SR的资源上发送所述SR。如果被所述eNB配置不允许同时发送PUCCH和PUSCH,或者所述UE确定被所述eNB配置允许同时发送PUCCH和PUSCH且所述UE确定在所述上行子帧上没有PUSCH发送,则所述UE用所述第一PUCCH格式在所述上行子帧 的所述PUCCH资源上发送所述CSI以及所述SR。
可选地,所述UE还可以确定第二上行信道资源,所述第二上行信道资源所述eNB为所述UE配置的用于发送SR的资源。
本发明类似实施例中,所述UE确定所述第一上行信道资源的格式是第一PUCCH格式还是第二PUCCH格式,当所述UE确定所述第一上行信道资源为具有第二PUCCH格式的PUCCH资源时,所述UE进一步确定第二上行信道资源,并在所述上行子帧的所述第二上行信道资源上发送SR,并且所述UE不发送所述CSI。其中,所述第二上行信道资源是为所述UE配置的用于发送SR的资源。由于所述第一上行信道资源为具有第二PUCCH格式的PUCCH资源时,所述PUCCH资源上不支持同时发送所述CSI和所述SR。因此所述UE不能同时发送所述CSI和所述SR。考虑所述SR的重要性高于所述CSI,所述UE不发送所述CSI,而是在第二上行信道资源中发送SR。所述第二PUCCH格式为上述的PUCCH format 2格式。而当所述UE确定所述第一上行信道资源为具有第一PUCCH格式的PUCCH资源时,则所述UE在所述上行子帧的所述第一上行信道资源上发送CSI和SR。
可选地,所述UE确定第二上行信道资源,所述第二上行信道资源所述eNB为所述UE配置的用于发送SR的资源。当所述UE确定所述第一上行信道资源为具有第一PUCCH格式的PUCCH资源时,如果所述UE同时确定被配置不允许在具有第一PUCCH格式的第一上行信道资源上发送SR时,所述UE在所述上行子帧的所述第二上行信道资源上发送SR,并且所述UE不发送所述CSI。
205、所述UE使用所述第一PUCCH格式在所述上行子帧的所述PUCCH资源上发送所述CSI以及所述SR时,所述UE确定在所述上行子帧中待发送的所述CSI所占用的比特数、所述SR所占用的比特数以及所述PUCCH资源的容量Na;以及所述UE确定所述CSI所占用的比特数与所述SR所占用比特数之和N1大于所述PUCCH资源的容量Na,丢弃优先级低的N2个比特的CSI,其中,N2满足N1-N2≤Na
假设eNB为UE配置共有L个载波需反馈周期CSI的信息,假设在Subrame#n的各载波需反馈的周期CSI的比特数分别为Nsubrame_n-cc_1、Nsubrame_n-cc_2、…、 Nsubrame_n-cc_L,其中0≤Nsubrame_n-cc_N(N=1,2,...L)≤Nmax,Nmax为对一个载波反馈周期CSI的最大比特数。即在Subrame#n中,配置该UE反馈的周期CSI的比特数为
Figure PCTCN2015087053-appb-000003
N0为所述eNB通过无线资源控制(Radio Resource Control,英文缩写:RRC)为所述UE配置且处于激活状态的载波中在当前子帧需反馈的周期CSI的总比特数,即
Figure PCTCN2015087053-appb-000004
载波数L为当前通过RRC为UE配置且处于激活状态的载波的个数。
而发送SR可以预先设置为1比特,即所述SR所占用的比特数为1;所述PUCCH资源的容量可通过eNB对UE的配置信息得到。所述PUCCH资源的容量指的是在所述PUCCH资源上可以发送的上行控制信息比特数的最大值。当所述CSI所占用的比特数与所述SR所占用比特数之和N1大于所述PUCCH资源的容量Na时,则所述UE无法通过所述PUCCH资源将所有的CSI以及SR发送给所述eNB,由于SR的优先级高于CSI,所以SR必须发送,而多个CSI中,存在优先级较低的CSI,则通过判断CSI的优先级,丢弃N2个低优先级的CSI,以使得N1-N2≤Na
本发明实施例中,CSI为周期CSI,第一上行信道资源为PUCCH资源,所述PUCCH资源为具有第一PUCCH格式的资源时,UE能够通过所述PUCCH资源在同一上行子帧上发送所述CSI以及SR;当所述PUCCH资源的容量小于待发送的CSI所占的比特数以及SR所占的比特数之和时,则丢弃一部分优先级低的CSI,这样,保证了所述UE可以发送重要的上行控制信息SR,而且可以发送尽可能多的周期CSI信息,提高了所述eNB对UE资源调度的准确性;当所述UE确定的PUCCH资源为具有第二PUCCH格式的资源时,由于具有第二PUCCH格式的资源上不能发送所述SR,则所述UE确定所述eNB为所述UE配置的用于发送SR的第二上行信道资源,并在所述第二信道资源上发送所述SR,并且所述UE不发送所述CSI。这样,保证了SR可以发送所述eNB,保证了eNB与所述UE进行数据交互的效率。
上述实施例描述了CSI为周期CSI,第一上行信道资源为PUCCH资源; 当所述CSI为非周期CSI时,所述第一上行信道资源为PUSCH资源,下面进行具体描述。参照图9所示,本发明实施例中上行控制信息的发送方法的另一实施例包括:
301、用户设备UE确定上行子帧中待发送的上行控制信息包括信道状态信息非周期CSI,所述非周期CSI为基站eNB为所述UE配置的多个载波中的至少一个载波的非周期CSI;
eNB使用动态控制信息DCI中的“CSI request”控制位触发UE在PUSCH信道中发送非周期CSI。。所述UE通过接收的调度PUSCH的动态控制信息中“CSI request”位的值确定所述上行子帧中待发送的上行控制信息包括信道状态信息非周期CSI,所述非周期CSI为基站eNB为所述UE配置的多个载波中的至少一个载波的非周期CSI。
302、所述UE确定上行子帧中待发送的上行控制信息包括SR;
详细内容参照S102所述。需要说明的是,步骤301与步骤302的先后顺序此处不做限定。
303、所述UE为所述CSI确定PUSCH资源,所述PUSCH资源为所述eNB用动态控制信息DCI指示UE用于发送非周期CSI的资源,所述PUSCH资源中没有待发送的上行数据信息;所述PUSCH资源中第一固定位置的资源发送所述SR;
所述UE确定所述上行信道资源为PUSCH资源,且所述PUSCH资源中没有待发送的上行数据信息的方法为:
所述UE接收上行调度指示信息,如果上行调度指示信息为DCI format0,则确定其中的“CSI request”字段指示触发非周期CSI上报、上行调度指示信息中的“modulation and coding scheme and redundancy version”字段为29(IMCS=29),并且所述调度指示信息所调度的上行数据的RB数目小于第一阈值,则所述UE确定所述上行信道资源为PUSCH资源,且所述PUSCH资源中没有待发送的上行数据信息;
或者,如果上行调度指示信息为DCI format4,但其中只有一个传输块是使能的,则确定其中的“CSI request”字段指示触发非周期CSI上报、上行调度指示信息中使能的传输块对应的“modulation and coding scheme and  redundancy version”字段为29(IMCS=29),并且所述调度指示信息所调度的上行数据的RB数目小于第一阈值,则所述UE确定所述上行信道资源为PUSCH资源,且所述PUSCH资源中没有待发送的上行数据信息。
所述第一固定位置的资源为以下任意一种:
所述PUSCH资源中目标时刻前任意一个比特位的资源,所述目标时刻为对待发送的上行控制信息进行编码的时刻;可选的,可以为所述PUSCH资源中在目标时刻前的第一个比特位的资源;或者,
所述PUSCH资源中目标时刻前用于发送CRC校验编码的CRC比特位的资源,所述目标时刻为对待发送的上行控制信息进行编码的时刻;或者,
所述PUSCH资源中预设位置的资源单元;或者,
所述PUSCH资源中预设的用于承载参考信号的资源单元。
关于PUSCH资源中第一固定位置的资源的描述与步骤203所描述的关于PUCCH资源中第一固定位置的资源类似,具体不做赘述。
304、当所述UE确定被所述eNB配置不允许同时发送PUCCH和PUSCH时,所述UE在所述PUSCH资源上发送所述SR;
所述UE在所述PUSCH资源上发送所述CSI以及所述SR之前,需要确定所述UE被所述eNB配置为允许同时发送PUCCH和PUSCH还是不允许同时发送PUCCH和PUSCH。如果被配置为不允许同时发送PUCCH和PUSCH,在所述PUSCH资源上发送所述SR和所述CSI。如果被配置为允许同时发送PUCCH和PUSCH,则所述UE可以在PUSCH上发送所述CSI并且同时所述eNB为所述UE配置的用于发送SR的资源上发送所述SR。
可选地,所述UE还可以确定第二上行信道资源,所述第二上行信道资源所述eNB为所述UE配置的用于发送SR的资源。当所述UE确定被配置所述PUSCH的资源上不允许发送所述SR,则所述UE在所述上行子帧的所述第二上行信道资源上发送SR,并且所述UE不发送所述CSI。
可选地,当所述UE确定所述上行子帧中待发送的上行控制信息还包括混合自动重传请求确认HARQ-ACK时,所述UE在所述上行子帧的所述PUSCH的资源上发送所述CSI、所述SR,以及所述HARQ-ACK信息。所述HARQ-ACK为下行数据信道对应的确认信息或非确认信息。
所述PUSCH资源中设置有第二固定位置的资源用于发送所述HARQ-ACK的状态信息。
所述第二固定位置的资源为以下一种:
所述PUSCH资源中在目标时刻前任意N个比特位的资源,所述目标时刻为对待发送的上行控制信息进行编码的时刻;其中,N的值为所述HARQ-ACK的比特数;可选的,可以为所述PUSCH资源中在目标时刻前的前第2~N+1个比特位的资源,所述PUSCH资源中在目标时刻前的第一个比特位的资源用于发送SR;或者,
PUSCH资源中预设位置的资源单元。
具体的,所述PUSCH资源中的第二固定位置的资源为所述PUSCH资源中在目标时刻前任意位置N个比特位的资源,所述目标时刻为对待发送的上行控制信息进行编码的时刻。可选的,所述第二固定位置的资源为PUSCH资源中在目标时刻前的第2~N+1个比特位的资源。上行控制信息在PUSCH资源中发送前,首先经过信道编码,然后对编码后的数据调制后发送。所述PUSCH资源中的第二固定位置的资源为所述PUSCH资源中在目标时刻前任意位置的N个比特位的资源指的是SR、所述HARQ-ACK和所述CSI的信息级联时,其中固定位置的N个比特位的资源用于HARQ-ACK的信息。例如,固定的位置为第2~N+1个比特位。
具体的,所述PUSCH资源中固定位置的资源为所述PUSCH资源中预设的时频位置的资源单元。上行控制信息在PUSCH资源中发送前,首先经过信道编码,然后对编码后的数据调制后发送。对于编码后的调制符号,采用预定义的规则映射到所述PUSCH资源的资源单元上。所述PUSCH资源中预设的时频位置的资源单元指的是在所述PUSCH资源的特定的资源单元上用于发送所述HARQ-ACK。例如预定义所述PUCCH资源中时域的第六个符号的资源单元用于映射所述HARQ-ACK。
本发明实施例中,CSI为非周期CSI,第一上行信道资源为PUSCH资源,并且所述PUSCH资源中没有待发送的上行数据信息。所述PUSCH资源中第一固定位置的资源发送所述SR,这样,在所述UE被指示发送非周期CSI且同时没有上行数据发送时,所述UE则能够通过所述PUSCH资源在同一上行 子帧上发送所述CSI以及SR,而不是丢弃所述CSI而只在所述eNB为所述UE配置的用于发送SR的资源上发送所述SR,提高了所述eNB对UE资源调度的准确性。
上述实施例描述了UE通过同一上行子帧向eNB发送CSI以及SR,在实际应用中,UE还可能需要通过同一上行子帧向eNB发送CSI以及HARQ-ACK,下面进行具体描述。参照图10所示,本发明实施例中上行控制信息的发送方法的另一实施例包括:
401、用户设备UE确定上行子帧中待发送的上行控制信息包括周期信道状态信息CSI以及混合自动重传请求确认HARQ-ACK,所述CSI为基站eNB为所述UE配置的多个载波中的至少一个载波的CSI;所述HARQ-ACK为所述多个载波中主载波的反馈信息,或者所述HARQ-ACK为所述多个载波中不大于预设数目载波的反馈信息;

所述HARQ-ACK为下行数据信道对应的确认信息或非确认信息。具体为,当UE在至少一个下行载波上接收到eNB发送的下行数据时,则需要通过上行子帧反馈下行数据传输对应的HARQ-ACK,以保证UE与eNB进行数据交互的准确性以及时效性。所述HARQ-ACK为所述多个载波中主载波的反馈信息指的是所述UE在所述上行子帧中需要对主载波的下行数据传输反馈HARQ-ACK信息。所述HARQ-ACK为所述多个载波中不大于预设数目载波的反馈信息指的是所述UE在所述上行子帧中需要对不大于预设数目载波的下行数据传输反馈HARQ-ACK信息。所述的预设数目可以是5个。
402、所述UE为所述CSI确定第一物理上行控制信道PUCCH资源,所述第一PUCCH资源为具有第一PUCCH格式的PUCCH资源;所述第一PUCCH资源为eNB为所述UE配置的用于发送CSI的资源;
具体的,所述第一PUCCH格式可以为上述新PUCCH格式一至新PUCCH格式六中的任意一种。
所述第一PUCCH格式具体为:所述第一PUCCH格式的容量大于预设比特数目,所述预设比特数目为11。其中,所述容量指的是在所述信道资源上 可以发送的上行控制信息的最大比特数。所述预设比特为第二PUCCH格式的容量。所述第二PUCCH格式指的是容量为11比特的上述的PUCCH format 2。
所述第一PUCCH格式还可以为:所述第一PUCCH格式采用卷积码编码。在具有第一PUCCH格式的PUCCH资源中可以发送的上行控制信息的比特数比在具有第二PUCCH格式的PUCCH资源中可以发送的上行控制信息的比特数更多。对于在具有第一PUCCH格式的PUCCH中可以发送的上行控制信息的比特数来说,采用卷积编码可以获得比里德穆勒(Reed Muller,RM)编码方式更高的编码增益。
403、所述UE使用所述第一PUCCH格式在所述上行子帧的所述第一PUCCH资源上发送所述CSI和所述HARQ-ACK;
所述UE使用所述第一PUCCH格式在所述上行子帧的所述第一PUCCH资源上发送所述CSI和所述HARQ-ACK。所述具有第一PUCCH格式的PUCCH资源发送所述CSI和所述HARQ-ACK时,其中第一固定位置的资源用于发送所述HARQ-ACK。所述PUCCH资源中固定位置的资源为以下一种:
所述PUCCH资源中在目标时刻前任意位置的N个比特位的资源,所述目标时刻为对待发送的上行控制信息进行编码的时刻;可选的,所述第二固定位置的资源为PUSCH资源中在目标时刻前的第2~N+1个比特位的资源;或者,

具体的,所述PUCCH资源中固定位置的资源为所述PUCCH资源中在目标时刻前任意位置的N个比特位的资源,所述目标时刻为对待发送的上行控制信息进行编码的时刻;可选的,所述第二固定位置的资源为PUSCH资源中在目标时刻前的第2~N+1个比特位的资源。上行控制信息在PUCCH资源中发送前,首先经过信道编码,然后对编码后的数据调制后发送。在所述PUCCH资源中发送所述CSI以及所述HARQ-ACK时,将所述HARQ-ACK信息和所述CSI的信息级联,首先经过信道编码,然后对编码后的数据调制后发送。所述PUCCH资源中固定位置的资源为所述PUCCH资源中在目标时刻前任意位置的N个比特位的资源指的是所述HARQ-ACK信息和所述CSI信息在信息在级联时,其中N个固定的位置用于HARQ-ACK的信息。例如,固定的位置为可选的,所述第二固定位置的资源为第2~N+1个比特位的资源。
具体的,所述PUCCH资源中固定位置的资源为所述PUCCH资源中预设的时频位置的资源单元。上行控制信息在PUCCH资源中发送前,首先经过信道编码,然后对编码后的数据调制后发送。对于编码后的调制符号,采用预定义的规则映射到所述PUCCH资源的资源单元上。所述PUCCH资源中预设的时频位置的资源单元指的是在所述PUCCH资源的特定的资源单元上用于发送所述HARQ-ACK。例如预定义所述PUCCH资源中时域的第三个符号和第五个符号中频率最低的六个资源单元用于映射所述HARQ-ACK。
当所述UE确定所述HARQ-ACK为所述多个载波中主载波的反馈信息,或者所述HARQ-ACK为所述多个载波中不大于预设数目载波的HARQ-ACK信息时,按照现有技术,所属UE在所述eNB为所述UE配置的第二PUCCH信道资源上发送所述HARQ-ACK,而不发送所述CSI。所述第二PUCCH信道资源为具有第三PUCCH格式的资源,所述第三PUCCH格式为上述的PUCCH format 1a或者PUCCH format 1b或者PUCCH format 3。所述预设数目的载波为5个。由于所述具有第三PUCCH格式的第二PUCCH资源上不能发送CSI或者最多只能发送一个载波的CSI最终影响所述eNB对UE的下行数据的调度。
本发明实施例中,所述UE确定上行子帧中待发送的上行控制信息包括信道状态信息CSI以及HARQ-ACK。所述HARQ-ACK为所述多个载波中主载波的反馈信息,或者所述HARQ-ACK为所述多个载波中不大于预设数目载波的HARQ-ACK时,所述UE为所述CSI确定第一PUCCH资源,所述第一PUCCH资源为具有第一PUCCH格式的PUCCH资源;所述第一PUCCH资源为eNB为所述UE配置的用于发送CSI的资源,那么,所述UE则能使用所述第一PUCCH格式在所述上行子帧的所述第一PUCCH资源上发送所述CSI和所述HARQ-ACK,这样,所述UE既能够通过所述第一PUCCH资源上发送所述HARQ-ACK,又能发送所述CSI,保证了所述eNB与所述UE进行数据交互的准确性与时效性,也提高了eNB对UE进行资源调度的准确性。
上述实施例描述了所述第一PUCCH资源为具有第一PUCCH格式的PUCCH资源;所述第一PUCCH资源为eNB为所述UE配置的用于发送CSI的资源。参照图11所示,本发明实施例中上行控制信息的发送方法的另一实 施例包括:

详细内容参照S402所述。
503、所述UE获取配置信息,所述配置信息用于指示允许所述UE在所述第一PUCCH格式的第一物理上行控制信道PUCCH资源上发送CSI和HARQ-ACK;
当eNB为UE配置了多个PUCCH资源时,所述eNB还会设置配置信息,所述配置信息指示了允许所述UE能够使用的具有第一PUCCH格式的PUCCH资源发送CSI和HARQ-ACK。
504、当所述UE确定被所述eNB配置不允许同时发送PUCCH和PUSCH,或者当所述UE确定被所述eNB配置允许同时发送PUCCH和PUSCH,且所述UE确定在所述上行子帧上没有PUSCH发送,所述UE确定所述HARQ-ACK为所述多个载波中主载波的反馈信息,或者所述HARQ-ACK为所述多个载波中不大于预设数目载波的反馈信息时,所述UE使用所述第一PUCCH格式在所述上行子帧的所述第一PUCCH资源上发送所述CSI和所述HARQ-ACK;
所述UE用所述第一PUCCH格式在所述上行子帧的所述PUCCH资源上发送所述CSI以及所述HARQ-ACK之前,需要确定所述UE被所述eNB配置为允许同时发送PUCCH和PUSCH还是不允许同时发送PUCCH和PUSCH。如果所述UE被所述eNB配置允许同时发送PUCCH和PUSCH且同时在所述上行子帧上有PUSCH发送,所述UE可以在所述待发送的PUSCH中发送所述CSI,并且同时在所述eNB为所述UE发送的调度主载波的数据的调度信息 的发送位置相对应的用于发送HARQ-ACK的资源上发送所述主载波HARQ-ACK反馈信息;或者所述UE可以在所述待发送的PUSCH中发送所述CSI,并且同时在所述eNB为所述UE预配置的用于发送多个载波中不大于预设数目载波的HARQ-ACK反馈信息的资源上发送所述多个载波中不大于预设数目载波的HARQ-ACK反馈信息。如果被所述eNB配置不允许同时发送PUCCH和PUSCH,或者所述UE确定被所述eNB配置允许同时发送PUCCH和PUSCH且所述UE确定在所述上行子帧上没有PUSCH发送,则所述UE用所述第一PUCCH格式在所述上行子帧的所述PUCCH资源上发送所述CSI以及所述HARQ-ACK。所述UE确定所述HARQ-ACK为所述多个载波中主载波的反馈信息,或者所述HARQ-ACK为所述多个载波中不大于预设数目载波的反馈信息时,所述UE使用所述第一PUCCH格式在所述上行子帧的所述第一PUCCH资源上发送所述CSI和所述HARQ-ACK的详细内容参照S403所述。
505、所述UE使用所述第一PUCCH格式在所述上行子帧的所述PUCCH资源上发送所述CSI以及所述HARQ-ACK时,所述UE确定在所述上行子帧中待发送的所述CSI所占用的比特数、所述HARQ-ACK所占用的比特数以及所述PUCCH资源的容量Ma;以及所述UE确定所述CSI所占用的比特数与所述HARQ-ACK所占用比特数之和M1大于所述PUCCH的容量Ma,丢弃优先级低的M2个比特的CSI,其中,M2满足M1-M2≤Ma
详细内容与S205所述的UE发送CSI与SR的方案类似,此处不做赘述。
本发明实施例中,所述UE获取配置信息,所述配置信息用于指示所述UE具备在所述第一PUCCH格式的第一PUCCH资源上发送CSI和HARQ-ACK的条件,这样,所述UE便能够根据所述配置信息确定能够使用的具有第一PUCCH格式的PUCCH资源,使得所述UE能够将所述CSI与所述HARQ-ACK发送给所述eNB;当所述CSI所占用的比特数与所述HARQ-ACK所占用比特数之和大于所述PUCCH的容量时,则所述UE丢弃一部分优先级低的CSI,这样,保证了所述UE可以发送尽可能多的周期CSI信息,提高了所述eNB对UE资源调度的准确性。
上述实施例描述了UE通过同一上行子帧在同一PUCCH资源上发送CSI 以及多个载波中主载波或者多个载波中不大于预设数目载波的HARQ-ACK信息给eNB,在实际应用中,当所述UE确定在所述上行子帧待发送的上行控制信息还包括SR时,则所述UE在同一上行子帧的同一PUCCH资源上同时发送SR、多个载波中主载波或者多个载波中不大于预设数目载波的HARQ-ACK以及CSI,下面进行具体描述,参照图12所示,本发明实施例中上行控制信息的发送方法的另一实施例包括:

602、所述UE确定待发送的上行控制信息还包括SR;
详细内容参照S202所述。
603、所述UE为所述CSI确定第一物理上行控制信道PUCCH资源,所述第一PUCCH资源为具有第一PUCCH格式的PUCCH资源;所述PUCCH资源具有第一PUCCH格式的PUCCH资源中第二固定位置的资源用于发送所述SR;
所述PUCCH资源具有第一PUCCH格式的PUCCH资源中第二固定位置的资源用于发送所述SR的具体内容,与S203所描述的具有第一PUCCH格式的PUCCH资源中固定位置的资源用于发送所述SR的方案类似,此处不做赘述。
604、所述UE获取配置信息,所述配置信息用于指示所述UE具备在所述第一PUCCH格式的物理上行控制信道PUCCH资源上发送CSI和HARQ-ACK的条件;
详细内容参照S503所述。

详细内容与S504所述的UE发送CSI与HARQ的方案类似,此处不做赘述。
606、所述UE使用所述第一PUCCH格式在所述上行子帧的所述PUCCH资源上发送所述CSI、所述HARQ-ACK以及所述SR时,所述UE确定在所述上行子帧中待发送的所述CSI所占用的比特数、所述HARQ-ACK所占用的比特数、所述SR所占用的比特数以及所述PUCCH资源的容量Ya;以及所述UE确定所述CSI所占用的比特数与所述HARQ-ACK所占用比特数以及所述SR所占用的比特数三者之和Y1大于所述PUCCH资源的容量Ya,丢弃优先级低的Y2个比特的CSI,其中,Y2满足Y1-Y2≤Ya
详细内容与S205所述的UE发送CSI与SR的方案类似,此处不做赘述。
本发明实施例中,当所述UE确定待发送的上行控制信息还包括SR时,则所述UE确定具有第一PUCCH格式的PUCCH资源,所述PUCCH资源设置有第二固定位置用于发送SR,这样,保证了UE能够向所述eNB发送SR,由于所述具有第一PUCCH格式的PUCCH资源同样能够发送HARQ-ACK以及CSI,则所述UE将所述SR、HARQ-ACK以及CSI通过同一上行子帧的同一PUCCH资源发送给eNB,这样,既提高了eNB与UE的进行数据交互的效率,也提高了所述eNB对UE资源调度的准确性。
