具体实施方式
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的一部分实施例，而不是全部实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都应属于本发明保护的范围。
应理解，本发明实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，简称为“GSM”)系统、 码分多址(Code Division Multiple Access，简称为“CDMA”)系统、宽带码分多址(Wideband Code Division Multiple Access，简称为“WCDMA”)系统、通用分组无线业务(General Packet Radio Service，简称为“GPRS”)、长期演进(Long Term Evolution，简称为“LTE”)系统、LTE频分双工(Frequency Division Duplex，简称为“FDD”)系统、LTE时分双工(Time Division Duplex，简称为“TDD”)、通用移动通信系统(Universal Mobile Telecommunication System，简称为“UMTS”)或全球互联微波接入(Worldwide Interoperability for Microwave Access，简称为“WiMAX”)通信系统等。
还应理解，在本发明实施例中，用户设备(User Equipment，简称为“UE”)可称之为终端(Terminal)、移动台(Mobile Station，简称为“MS”)、移动终端(Mobile Terminal)等，该用户设备可以经无线接入网(Radio AccessNetwork，简称为“RAN”)与一个或多个核心网进行通信，例如，用户设备可以是移动电话(或称为“蜂窝”电话)、具有移动终端的计算机等，例如，用户设备还可以是便携式、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音和/或数据。
在本发明实施例中，基站可以是GSM或CDMA中的基站(Base Transceiver Station，简称为“BTS”)，也可以是WCDMA中的基站(NodeB，简称为“NB”)，还可以是LTE中的演进型基站(Evolutional Node B，简称为“eNB或e-NodeB”)，本发明并不限定，但为描述方便，下述实施例将以eNB为例进行说明。
图1示出了根据本发明实施例的传输上行信息的方法100的示意性流程图，该方法100可以由用户设备侧设备执行，例如可以由UE执行。如图1所示，该方法100包括：
S110，用户设备确定物理上行共享信道PUSCH的发送功率；
S120，用户设备确定用于解调该PUSCH的解调参考信号DMRS的发送功率，该PUSCH的发送功率与该DMRS的发送功率不相等；
S130，用户设备根据该PUSCH的发送功率和该DMRS的发送功率分别发送该PUSCH和该DMRS。
具体而言，用户设备针对免许可频谱采用多簇频率资源的资源分配方式，发送的用于解调PUSCH的DMRS占用的频率资源数目比PUSCH占用的频率资源数目要更大，如果在DMRS的符号上采用和PUSCH符号上相同的发 送功率，不能保证DMRS的信道估计性能，用户设备通过分别确定PUSCH和用于解调该PUSCH的DMRS的发送功率，例如，可以首先确定PUSCH的符号上的发送功率，然后通过PUSCH和DMRS各自在一个符号上占用的频率资源数目确定该DMRS的发送功率，可以保证DMRS的信道估计性能。进一步地，还可以保证PUSCH和DMRS在免许可频谱的一次发送机会中同时发送，实现了通过发送不同于PUSCH的带宽的用于解调该PUSCH的DMRS信号，保证了信道估计的性能。应理解，单独确定的PUSCH的发送功率和单独确定的DMRS的发送功率也可以相同，本发明对此不限定。
因此，本发明实施例的方法，能够采用不同的发送功率发送PUSCH和用于解调该PUSCH的DMRS，提高了信道估计的性能。
LTE系统中上行业务的传输是基于基站调度的，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发送控制信道，比如物理下行控制信道(Physical Downlink Control Channel，PDCCH)或增强物理下行控制信道(Enhanced Physical Downlink Control Channel，EPDCCH)，该控制信道可以承载PUSCH的调度信息，该调度信息包括比如资源分配信息，调整编码方式等控制信息。用户设备通过检测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。
用户设备在一个上行子帧发送的上行数据信道为PUSCH，用于解调PUSCH数据的参考信号为DMRS。如图2所示，D0～D12为PUSCH信道占用的符号，图中DMRS所示位置为解调参考信号占用的符号。信道资源占用N(N≥1)个RB，在一般循环前缀(Normal Cyclic Prefix，Normal CP)的情况下，每个时隙的中间一个时域符号承载解调参考信号；在扩展循环前缀(Extended Cyclic Prefix，Extended CP)的情况下，每个时隙的第三个时域符号承载解调参考信号。
用户设备在PUSCH信道所在符号上的发送功率可以通过以下方式确定：
如果用户设备在服务小区c的子帧i上发送PUSCH而不发送物理上行控制信道(Physical Uplink Control Channel,PUCCH)，则该用户设备在服务小区c的子帧i发送PUSCH的功率PPUSCH,c(i)为：
Figure PCTCN2016073550-appb-000001
如果用户设备在服务小区c的子帧i上发送PUSCH并同时发送PUCCH，则该用户设备在服务小区c的子帧i发送PUSCH的功率PPUSCH,c(i)为：
Figure PCTCN2016073550-appb-000002
其中，MPUSCH,c(i)为PUSCH所占的RB数目；
PCMAX,c(i)为用户设备配置的在服务小区c上子帧i的最大发送功率，
Figure PCTCN2016073550-appb-000003
为PCMAX,c(i)的线性值；
Figure PCTCN2016073550-appb-000004
为子帧i发送的PUCCH发送功率的线性值；
PO_PUSCH,c(j)和αc(j)是用户设备通过高层信令确定的值；
PLc为用户设备测量得到的服务小区c到该用户设备的路径损耗值；
ΔTF,c(i)为用户设备根据该PUSCH发送的上行数据比特数和该PUSCH中包括的资源单元的个数的比值确定的值；
fc(i)为用户设备根据对该PUSCH的功率调整命令确定的值。
因此，用户设备可以通过PUSCH所占的频率资源数目确定PUSCH的发送功率，该频率资源数目可以以RB为单位，也可以以PRB为单位，或者以RE为单位。应理解，本发明只是以上述方法为例对确定PUSCH发送功率进行说明，对此并不构成限定。
用户设备也可通过DMRS所占的频率资源数目确定DMRS的发送功率。
如果用户设备在服务小区c的子帧i上发送PUSCH而不发送PUCCH，则该用户设备在服务小区c的子帧i发送DMRS的功率PDMRS,c(i)为：
Figure PCTCN2016073550-appb-000005
如果用户设备在服务小区c的子帧i上发送PUSCH并同时发送PUCCH，则该用户设备在服务小区c的子帧i发送DMRS的功率PPUSCH,c(i)为：
Figure PCTCN2016073550-appb-000006
其中，MDMRSc(i)为DMRS的符号上所占的RB数目，其它参数与公式(1)和公式(2)中相同。
优选地，用户设备根据该PUSCH的发送功率，确定用于解调该PUSCH的DMRS的发送功率，该PUSCH的发送功率与该DMRS的发送功率的比值与该PUSCH在一个符号上占用的频率资源数目和该DMRS在一个符号上 占用的频率资源数目的比值相等。例如，在一个发送PUSCH的符号上，发送PUSCH的频率资源数目为
Figure PCTCN2016073550-appb-000007
个RE，在一个发送DMRS的符号上，发送DMRS的频率资源数目为
Figure PCTCN2016073550-appb-000008
个RE，则第一发送功率和第二发送功率的比值为
Figure PCTCN2016073550-appb-000009
假设PUSCH的发送功率为P1，DMRS的发送功率为P2，则用户设备可以在确定PUSCH的发送功率之后，可以按照
Figure PCTCN2016073550-appb-000010
确定出DMRS的发送功率。
应理解，本发明只是以上述方法为例对确定DMRS的发送功率进行说明，对此并不构成限定。
应理解，本发明实施例只是针对在免许可频谱上共同发送PUSCH和用于解调该PUSCH的DMRS时，由于功率不同所带来的技术问题，但本发明的技术方案也可以应用于许可频谱上，为了描述方便，下面以在免许可频谱上发送PUSCH和DMRS为例进行说明。
可选地，该用户设备根据该PUSCH的发送功率和该DMRS的发送功率分别发送该PUSCH和该DMRS，包括：该用户设备根据该PUSCH的发送功率和该DMRS的发送功率确定目标能量检测门限值；该用户设备根据该目标能量检测门限值和免许可频谱资源是否空闲的检测规则确定用于发送该PUSCH和该DMRS的免许可频谱资源是否空闲；该用户设备在确定该免许可频谱资源空闲时，根据该PUSCH的发送功率和该DMRS的发送功率分别发送该PUSCH和该DMRS。
为实现多个通信系统占用免许可频谱资源上互不影响的共存特性，无线通信设备在占用免许可频谱通信时需要使用先听后讲(Listen Before Talk,LBT)规则来检测免许可频谱资源是否空闲。具体而言，用户设备在接入到免许可频谱时，需要首先通过能量检测过程确定免许可频谱资源空闲，才能占用免许可频谱资源发送上行信息。用户设备检测免许可频谱资源上接收到的信号能量并和能量检测门限值比较可确定出免许可频谱资源是否空闲的检测结果。如果用户设备在免许可频谱资源上接收到的信号能量大于能量检测门限值，则用户设备判断免许可频谱资源被占用，不可以在这些资源上发送信号。否则如果用户设备在免许可频谱资源上接收到的信号能量小于能量检测门限值，则用户设备判断免许可频谱资源空闲，可以发送信号。
用户设备检测免许可频谱资源是否空闲的门限值至少与该用户设备在该免许可频谱资源上发送的上行信息的发送功率有关，或者还与发送的上行 信息占用的频率资源有关。例如，用户设备检测免许可频谱资源是否空闲的目标能量检测门限值的上限值为能量检测阈值XThresh_max：
Figure PCTCN2016073550-appb-000011
其中，TA为根据用户设备发送的上行信息类型确定的预设值；
PH＝23dBm；
PTX为用户设备的发送功率；
Tmax(dBm)＝10·log10(3.16228·10-8(mW/MHz)·BWMHz(MHz))
BWMHz是用MHz表示的用户设备发送上行信息所占用的频率资源数目。
用户设备针对免许可频谱采用多簇频率资源的资源分配方式，发送的用于解调PUSCH的DMRS占用的频率资源数目比PUSCH占用的频率资源数目要更大，发送功率不相等。这样，用户设备按照PUSCH的发送功率和DMRS的发送功率确定用于检测免许可频谱资源是否空闲的能量检测门限值不相同。为了避免用户设备在发送PUSCH和DMRS时分别做免许可频谱资源是否空闲的检测，可以将发送PUSCH的用于检测免许可频谱资源是否空闲的目标能量检测门限值与将发送DMRS的用于检测免许可频谱资源是否空闲的目标能量检测门限值设为统一的门限值，以此提高上行信息的发送效率。
如果用户设备使用该目标能量检测门限值，通过接入信道的流程确定上行信道资源空闲，则该UE可以在该免许可频谱的一次发送机会中同时发送所述的PUSCH和DMRS信号，实现了通过发送不同于PUSCH的带宽的用于解调该PUSCH的DMRS信号保证了信道估计的性能的目的。
应理解，用户设备接入信道的流程在本发明不作特别限定。如果检测出免许可频谱资源空闲，用户设备可以发送PUSCH和DMRS，如果检测出免许可频谱资源不空闲，用户设备则不发送PUSCH和DMRS。
可选地，该用户设备根据该PUSCH的发送功率和该DMRS的发送功率确定目标能量检测门限值，包括：当根据PUSCH的发送功率确定的PUSCH对应的第一能量检测阈值为XThresh_max_1，当根据DMRS的发送功率确定的DMRS对应的第二能量检测阈值为XThresh_max_2时，确定UE检测免许可频谱资源是否空闲的目标能量检测门限值为X，其中X不大于 min(XThresh_max_1,XThresh_max_2)，其中“min”为选择两个参数数值较小的参数的函数。
应理解，用户设备可以根据公式(5)来确定第一能量检测阈值为XThresh_max_1和第二能量检测阈值为XThresh_max_2，该XThresh_max_1和XThresh_max_2至少分别由PUSCH和DMRS的发送功率确定，或者还可以分别由PUSCH和DMRS占用的频率资源的大小确定。
优选地，该第一能量检测阈值为XThresh_max_1和该第二能量检测阈值为XThresh_max_2相等。
用户设备可以在根据PUSCH的发送功率确定完PUSCH对应的第一能量检测阈值之后，可以根据第一能量检测阈值和DMRS对应的第二能量检测阈值相等，确定出DMRS的发送功率。例如，根据公式
T1max-PTX1＝T2max-PTX2                  (6)
可计算出DMRS的发送功率PTX2，其中PUSCH和DMRS所占的频率资源数目已知，PUSCH的发送功率PTX1可根据公式(1)或(2)确定，由此，可计算出DMRS的发送功率。
同时，将不小于PUSCH的第一能量检测阈值XThresh_max_1的值X确定为UE检测免许可频谱资源是否空闲的目标能量检测门限值，并根据该目标能量检测门限值和UE检测免许可频谱资源是否空闲的规则，确定上行信道资源是否空闲，使得用户设备无需分别针对PUSCH和DMRS在免许可频谱资源上做空闲检测，从而提高了上行发送效率。
相应的，基站侧接收用户设备发送的PUSCH和用于解调该PUSCH的DMRS，该PUSCH的发送功率和该DMRS的发送功率不相同；基站根据该PUSCH的发送功率和该DMRS的发送功率的比值解调该PUSCH。
具体而言，基站用DMRS解调PUSCH，与该PUSCH发送功率和该DMRS的发送功率比值有关，例如：假设DMRS信号为S2，发送功率为P2；PUSCH信号为S1，发送功率为P1，则根据S2解调出来的S1为
Figure PCTCN2016073550-appb-000012
因此，基站根据用户设备发送DMRS的发送功率和该UE发送PUSCH的发送功率完成信道估计以及PUSCH信道解调的过程，可以实现在UE发送不同于PUSCH的带宽的用于解调该PUSCH的DMRS信号下，保证了信道估计的性能以及PUSCH数据解调性能的目的。
图3示出了根据本发明实施例的传输上行信息的方法200的示意性流程图，该方法200可以由用户设备侧设备执行，例如可以由UE执行。如图3 所示，该方法200包括：
S210，用户设备确定在至少一个上行子帧的时间内待发送的第一上行信息和第二上行信息；
S220，该用户设备根据该第一上行信息或该第二上行信息占用的频率资源数目确定功率调整值；
S230，该用户设备根据该功率调整值确定该第一上行信息的第一发送功率和该第二上行信息的第二发送功率；
S240，该用户设备根据该第一发送功率和该第二发送功率分别发送该第一上行信息和该第二上行信息。
具体而言，用户设备在根据第一上行信息或第二上行信息所占用的频率资源数目确定功率调整值之后，再根据该功率调整值确定第一上行信息的第一发送功率和第二上行信息的第二发送功率，并根据该第一发送功率和该第二发送功率分别发送该第一上行信息和该第二上行信息。
因此，本发明实施例的方法，根据该第一上行信息或该第二上行信息占用的频率资源数目确定功率调整值，能够在第一上行信息和第二上行信息占用的频率资源数目不相等的情况下，提高在免许可频谱的载波上的数据发送效率。
在LTE系统中，eNode B使用SRS来估计不同频段的上行信道质量。如果SRS在某个子帧上发送，则SRS将占据该子帧的最后一个symbol，因此SRS和DMRS位于不同的单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)symbol上。如果最后一个SC-FDMA symbol分配给了SRS，则该symbol不能用于PUSCH传输。SRS通常会覆盖一个和PUSCH不同且通常更大的频带。
可选地，该用户设备根据该功率调整值确定该第一上行信息的第一发送功率和第二上行信息的第二发送功率，包括：
该用户设备根据该第一上行信息和该第二上行信息中所占用的频率资源数目的最大值确定该功率调整值。
可选地，第一上行信息可以是PUSCH，第二上行信息可以是SRS，若PUSCH所占用的频率资源数目大于SRS所占用的频率资源数目，则用户设备可以根据PUSCH的频率资源数目确定该功率调整值，如10log10(MPUSCH,c(i))。并可以根据该功率调整值分别确定第一发送功率和第二发送功率，例如：用 户设备可以根据公式(2)确定PUSCH的第一发送功率，用户设备可以将确定SRS的第二发送功率公式(7)中的功率调整值10log10(MSRS,c)中的SRS所占的频率资源数目MSRS,c修改为PUSCH所占的频率资源数目MPUSCH,c(i)。
PSRS,c(i)＝min{PCMAX,c(i),PSRS_OFFSET,c(m)+10log10(MSRS,c)+PO_PUSCH,c(j)+αc(j)·PLc+fc(i)}     (7)
其中PCMAX,c(i)、PO_PUSCH,c(j)、αc(j)、PLc、fc(i)的含义和上述公式(1)、(2)中的含义相同。
PSRS_OFFSET,c(m)是通过高层信令为用户设备配置的值。
MSRS,c是服务小区c的子帧i中发送SRS所占的频率资源数目。
可选地，若SRS所占用的频率资源数目大于PUSCH所占用的频率资源数目，则用户设备可以根据SRS的频率资源数目确定该功率调整值，如10log10(MSRS,c)。并可以根据该功率调整值分别确定第一发送功率和第二发送功率，例如：用户设备可以根据公式(7)确定SRS的第二发送功率，用户设备可以将确定PUSCH的第一发送功率的公式(2)中的功率调整值10log10(MPUSCH,c(i))中PUSCH所占的频率资源数目MPUSCH,c(i)修改为SRS所占的频率资源数目MSRS,c。
可选地，第一上行信息和第二上行信息还可以是不同上行子帧发送的PUSCH，第一上行信息和第二上行信息还可以是在不同上行子帧内发送的PUSCH和SRS，本发明对待发送的上行信息的个数也不限定。
可选地，该用户设备根据该第一发送功率和该第二发送功率分别发送该第一上行信息和该第二上行信息，包括：该用户设备根据该第一发送功率和该第二发送功率分别确定第一能量检测阈值XThresh_max_1和第二能量检测阈值XThresh_max_2，并且确定UE检测免许可频谱资源是否空闲的目标能量检测门限值为X，其中X不大于min(XThresh_max_1,XThresh_max_2)，其中“min”为选择两个参数数值较小的参数的函数；该用户设备根据该目标能量检测门限值和免许可频谱资源是否空闲的检测规则确定用于发送该第一上行信息和该第二上行信息的免许可频谱资源是否空闲；该用户设备在确定该免许可频谱资源空闲时，发送该第一上行信息和该第二上行信息。
应理解，根据本发明实施例确定的第一发送功率和第二发送功率可以相同也可以不同，本发明对此不限定。
为实现多个通信系统占用免许可频谱资源上互不影响的共存特性，无线通信设备在占用免许可频谱通信时需要使用先听后讲(Listen Before  Talk,LBT)规则来检测免许可频谱资源是否空闲。具体而言，用户设备在接入到免许可频谱时，需要首先通过能量检测过程确定免许可频谱资源空闲，才能占用免许可频谱资源发送上行信息。用户设备检测免许可频谱资源上接收到的信号能量并和能量检测门限值比较可确定出免许可频谱资源是否空闲的检测结果。如果用户设备在免许可频谱资源上接收到的信号能量大于检测门限值，则用户设备判断免许可频谱资源被占用，不可以在这些资源上发送信号。否则如果用户设备在免许可频谱资源上接收到的信号能量小于检测门限值，则用户设备判断免许可频谱资源空闲，可以发送信号。
用户设备检测免许可频谱资源是否空闲的门限值至少与该用户设备在该免许可频谱资源上发送的上行信息的发送功率有关，或者还与发送的上行信息占用的频率资源有关。例如，用户设备检测免许可频谱资源是否空闲的能量检测门限值可以由公式(5)计算获得。
为了避免用户设备在发送第一上行信息和第二上行信息时分别做免许可频谱资源是否空闲的检测，可以将发送第一上行信息的用于检测免许可频谱资源是否空闲的目标能量检测门限值与将发送第二上行信息的用于检测免许可频谱资源是否空闲的目标能量检测门限值设为统一的门限值，以此提高上行信息的发送效率。
用户设备可以根据接入信道的流程确定是否可以占用免许可频谱资源发送第一上行信息和第二上行信息，应理解，用户设备接入信道的流程在本发明不作特别限定。如果检测出免许可频谱资源空闲，用户设备可以发送第一上行信息和第二上行信息，如果检测出免许可频谱资源不空闲，用户设备则不发送第一上行信息和第二上行信息。
应理解，用户设备可以根据公式(5)来确定XThresh_max_1和XThresh_max_2，该XThresh_max_1和XThresh_max_2至少分别由第一发送功率和第二发送功率确定，或者还分别由第一上行信息和第二上行信息占用的频率资源的大小确定。
优选地，该第一发送功率和该第二发送功率相等，该第一能量检测阈值和该第二能量检测阈值相等。
具体而言，用户设备可以忽略公式(2)中的ΔTF,c(i)，并且将公式(7)中的PSRS_OFFSET,c(i)等于0，这样，可以将第一发送功率和第二发送功率设置为相同的值，因此，在使用相同的频率资源数目的情况下，根据公式(5)可以将第一能量检测阈值和第二能量检测阈值设置为相同的值，使得用户设备无需分别 针对第一上行信息和第二上行信息在免许可频谱资源上做空闲检测，从而提高了上行发送效率。
相应的，基站侧接收用户设备按照第一发送功率发送的第一上行信息，和用第二发送功率发送的第二上行信息，能够在第一上行信息和第二上行信息占用的频率资源数目不相等的情况下，提高了免许可频谱的载波上的数据发送效率。
图4示出了根据本发明实施例的传输上行信息的方法300的示意性流程图，该方法300可以由用户设备侧设备执行，例如可以由UE执行。如图4所示，该方法300包括：
S310，用户设备确定在至少一个上行子帧的时间内待发送的第一上行信息和第二上行信息；
S320，用户设备分别确定该第一上行信息的第一发送功率和该第二上行信息的第二发送功率；
S330，用户设备根据该第一发送功率和该第二发送功率中的最大值发送该第一上行信息和该第二上行信息。
具体而言，用户设备确定在至少一个上行子帧的时间内待发送的第一上行信息和第二上行信息时，如果用户设备确定第一上行信息的发送功率为第一发送功率，确定第二上行信息的发送功率为第二发送功率，则该用户设备使用目标发送功率发送第一上行信息，并使用目标发送功率发送第二上行信息。该目标发送功率为该第一发送功率和该第二发送功率中的最大值。
因此，本发明实施例的方法，根据该第一上行信息的第一发送功率和第二上行信息的第二发送功率中的最大值发送第一上行信息和第二上行信息，能够提高在免许可频谱的载波上的数据发送效率。
可选地，该第一上行信息为物理上行共享信道PUSCH，该第二上行信息为探测参考信号SRS。或者该第一上行信息和该第二上行信息为不同的上行子帧中的PUSCH。
可选的，该用户设备通过公式(1)或(2)确定PUSCH信息的第一发送功率，通过公式(7)确定SRS的第二发送功率。
可选的，该用户设备使用目标发送功率发送第一上行信息，并使用目标发送功率发送第二上行信息之前，根据确定UE检测免许可频谱资源是否空闲的目标能量检测门限值为X，该X的值不大于XThresh_max，该XThresh_max的值 至少可以由该目标发送功率确定。例如，用户设备可以根据公式(5)来确定和该目标发送功率对应的XThresh_max。除了和该目标发送功率相关之外，该XThresh_max还可以和该目标发送功率对应的上行信息占用的频率资源的大小相关。
用户设备可以根据接入信道的流程和目标能量检测门限值X确定是否可以占用免许可频谱资源发送第一上行信息和第二上行信息，应理解，用户设备接入信道的流程在本发明不作特别限定。如果检测出免许可频谱资源空闲，用户设备可以发送第一上行信息和第二上行信息，如果检测出免许可频谱资源不空闲，用户设备则不发送第一上行信息和第二上行信息。
相应的，基站侧接收该用户设备按照目标发送功率发送的第一上行信息和用目标发送功率发送的第二上行信息，能够在第一上行信息和第二上行信息占用的频率资源数目不相等的情况下保证第一上行信息和第二上行信息在免许可频谱的一次发送机会中同时发送，从而提高了免许可频谱的载波上的数据发送效率。
上文中结合图1至图4，详细描述了根据本发明实施例的传输上行信息的方法，下面将结合图5至图7，详细描述根据本发明实施例的用户设备。
如图5所示，根据本发明实施例的用户设备400包括：
第一确定模块410，用于确定物理上行共享信道PUSCH的发送功率；
第二确定模块420，用于确定用于解调该PUSCH的解调参考信号DMRS的发送功率，该PUSCH的发送功率与该DMRS的发送功率不相等；
发送模块430，用于根据该PUSCH的发送功率和该DMRS的发送功率分别发送该PUSCH和该DMRS。
因此，本发明实施例的用户设备，能够采用不同的发送功率发送PUSCH和用于解调该PUSCH的DMRS，提高了信道估计的性能。
如图6所示，根据本发明实施例的用户设备500包括：
第一确定模块510，用于确定在至少一个上行子帧的时间内待发送的第一上行信息和第二上行信息；

第三确定模块530，用于根据该功率调整值确定该第一上行信息的第一发送功率和该第二上行信息的第二发送功率；
发送模块540，用于根据该第一发送功率和该第二发送功率分别发送该第一上行信息和该第二上行信息。
因此，本发明实施例的用户设备，根据该第一上行信息或该第二上行信息占用的频率资源数目确定功率调整值，能够在第一上行信息和第二上行信息占用的频率资源数目不相等的情况下，提高在免许可频谱的载波上的数据发送效率。
如图7所示，根据本发明实施例的用户设备600包括：
第一确定模块610，用于确定在至少一个上行子帧的时间内待发送的第一上行信息和第二上行信息；
第二确定模块620，用于分别确定该第一上行信息的第一发送功率和该第二上行信息的第二发送功率；
发送模块630，用于根据该第一发送功率和该第二发送功率中的最大值发送该第一上行信息和该第二上行信息。
因此，本发明实施例的用户设备，根据该第一上行信息的第一发送功率和第二上行信息的第二发送功率中的最大值发送第一上行信息和第二上行信息，能够提高在免许可频谱的载波上的数据发送效率。
根据本发明实施例的用户设备400、500和600可对应于本发明实施例中的用户设备，并且用户设备400、500和600中的各个模块的上述和其它操作和/或功能分别为了实现图1至图4中的各个方法的相应流程，为了简洁，在此不再赘述。
本发明实施例还提供了一种传输上行信息的基站，该基站包括：
接收模块，用于接收物理上行共享信道PUSCH和用于解调所述PUSCH的解调参考信号DMRS，所述PUSCH的发送功率和所述DMRS的发送功率不同；
解调模块，用于根据所述PUSCH的发送功率和所述DMRS的发送功率的比值解调所述PUSCH。
因此，本发明实施例的基站，根据用户设备发送DMRS的发送功率和该UE发送PUSCH的发送功率完成信道估计以及PUSCH信道解调的过程，可以实现在UE发送不同于PUSCH的带宽的用于解调该PUSCH的DMRS信号下，保证了信道估计的性能以及PUSCH数据解调性能的目的。
本发明实施例还提供了另外一种传输上行信息的基站，该基站包括：
