Description

一种传输信号的方法和设备 技术领域
本发明涉及通信领域，特别涉及一种传输信号的方法和设备。
背景技术
目前蜂窝通信系统采用频分双工(Frequency division duplex，FDD)和时分双工(Time division duplex，TDD)两种方式。FDD是在分离的两个成对(pair)信道上进行接收和发送，并且用保护频段来分离上行(Uplink，终端发送，基站接收)和下行(downlink，基站发送，终端接收)信道。TDD是通过不同上下行配比实现在相同的频率资源上的不同子帧进行上下行传输。目前无线频谱越来越紧张，而且业务也灵活多变。FDD和TDD的缺点越来越突显，FDD需要成对频谱，并且上下行资源一样多，使得频谱划分较为困难，对于非对称业务，上行资源可能利用不充分。TDD在组网的时候，同频网络为了避免上下行干扰，必须采用相同配比，使得上下行资源不能完全按照小区的业务配置。为了解决FDD和TDD的缺点，FDD和TDD也不断演进。一种方式是在TDD的频段实现上下行灵活配置，通过控制小区间的干扰提高网络吞吐量。另一种方法FDD上行频段中也划分部分上行资源，匹配更多样的业务类型。
近年来，由斯坦福大学，莱斯大学等提出一种单信道全双工技术(single channel full duplex)，也被称为同时同频收发技术(transmit and receive at the same time on the same frequency)或者无线全双工技术。无线全双工技术不同于现有的FDD或TDD技术，实现了在同一频段上同时发送和接收数据。在相同无线信道上同时进行接收与发送操作，理论上无线全双工技术的频谱效率是FDD或TDD技术的两倍。如果将全双工技术引入蜂窝网络，可以成为解决FDD和TDD缺点的另一种方法，因此具有很重要的意义。
然而，由于无线信号在无线信道中的衰减非常大，与全双工设备自身的发射信号相比，来自通信对端的上行信号到达接收端(全双工设备)时信号已非常微弱，例如，移动蜂窝通信系统中一个通信节点的收发信号功率差达到80dB～140dB甚至更大，因此，全双工设备存在的发射信号对接收信号的自干扰，即使现有技术采取了全双工设备的自干扰消除的措施，但是现有技 术无法完全消除全双工设备的自干扰，仍然存在自干扰残留。全双工引入蜂窝网络中会在现在的FDD或TDD系统上，自干扰残留问题仍然存在，对全双工设备接收的上行信号造成很大影响，造成上行信号的接收信号噪声比下降。因此，希望提供一种技术，能够消除或降低全双工系统中的自干扰残留对上行信号接收的不利影响。

基于上述技术方案，本发明实施例通过第一设备采用上行传输功率是根据所述第二设备的自干扰补偿量确定的功率，或者上行传输功率为所述第一设备的最大发送功率的功率向工作在全双工模式下的第二设备发送上行信号，由于本发明实施例通过第二设备的自干扰补偿量来降低第二设备的自干扰残留量对上行信号接收的不利影响，或第一设备采用最大发送功率发送上行信号来消除第二设备的自干扰残留量对上行信号接收的不利影响，因此，本发明实施例能够消除或降低第二设备的自干扰残留量对上行信号接收的不利影响，能够提升网络性能。

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：长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、无线高保真(WIreless-Fidelity，WI-FI)通信系统或全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统等。
本发明实施例可以用于不同的制式的无线网络。无线接入网络在不同的系统中可包括不同的网元。例如，包括基站、接入点(Access Point，AP)、中继(Relay)等。具体地，例如，LTE和LTE-A中无线接入网络的网元包括eNB(eNodeB，演进型基站)，WCDMA中无线接入网络的网元包括RNC(Radio Network Controller，无线网络控制器)和NodeB，类似地，WiMax(Worldwide Interoperability for Microwave Access，全球微波互联接入)等其它无线网络也可以使用与本发明实施例类似的方案，只是基站系统中的相关模块可能有所不同，本发明实施例并不限定，但为描述方便，下述实施例中的基站将以eNodeB和NodeB为例进行说明。
还应理解，在本发明实施例中，用户设备(UE，User Equipment)包括但不限于移动台(MS，Mobile Station)、移动终端(Mobile Terminal)、移动电话(Mobile Telephone)、手机(handset)及便携设备(portable equipment)等，该用户设备可以经无线接入网(RAN，Radio Access Network)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)、具有无线通信功能的计算机等，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
图1是本发明实施例可应用的全双工系统部署场景图。如图1所示的全双工系统场景包括基站110、用户设备120和用户设备130，
基站110具有全双工能力，用户设备120具有半双工能力。当基站110同时同频收发时，可以通过调度覆盖范围内的一部分终端，例如用户设备120处于上行发射，另一部分终端例如用户设备130处于下行接收。
应理解，图1中的基站110也可以用小站(small cell)或接入点(Access Point)等来代替，本发明实施例并不对此做限定。
应注意，图1所示的场景中仅示出了一个有一个基站(孤立基站)的情形，但本发明实施例并不限于此，基站110还可以有在相同的时频资源上传输业务的近邻基站(站点)和用户设备(图未示)。
图2是另一本发明实施例可应用的全双工系统部署场景图。如图2所示的全双工系统场景包括中继210、基站220和用户设备230。中继210具有全双工能力，中继210进行全双工传输时，中继210采用相同的时频资源接收来自基站220的信号和向用户设备230发送下行信号，或者中继210采用相同的时频资源接收来自用户设备230的信号和向基站220发送下行信号。
图3是根据本发明一个实施的传输信号的方法的示意性流程图。图3的方法由第一设备执行，应用于图1场景中，第一设备可以是用户设备，应用于图2场景中，第一设备可以是基站或用户设备。具体地，如图3所示的方法包括：
310，第一设备确定上行传输功率。
换句话说，第一设备确定向第二设备发送上行信号的上行传输功率。
320，第一设备采用上行传输功率在第一时频资源上向工作在全双工模式下的第二设备发送上行信号，其中，上行传输功率是根据第二设备的自干扰补偿量确定的功率，或者上行传输功率为第一设备的最大发送功率。
具体地，第二设备为具有同时同频发送信号和接收信号的能力的全双工设备。例如，第二设备可以为基站或中继等。
应理解，第一时频资源可以为全双工时频资源，全双工时频资源表示在该资源上既同时承载有上行业务和下行业务。第二设备在该全双工时频资源上也可以向另外的一个设备发送下行信号。也就是说第二设备在该全双工时频资源上即可以接收第一设备发送的上行信号，还可以向另外一个设备发送信号。
需要说明的一点是，全双工设备是指具有同时同频收发信号的能力的设备，全双工设备可以有多种工作模式，例如全双工模式和半双工模式等，全双工设备可以工作在全双工模式下，也可以回退(切换)到半双工模式下。全双工设备可以根据系统的中干扰，业务，用户分布等情况确定工作在全双工模式下还是半双工模式下。
其中，全双工设备工作在全双工模式下，也可以处于两种状态，一种是全双工通信，对应的资源为全双工时频资源，即全双工设备在全双工时频资 源上即发送数据又接收数据。另外一种为全双工监听，对应的资源为半双工下行资源，即全双工设备在半双工下行资源上发送数据，接收链路仅作为监听或测量干扰，并不解调接收数据。全双工设备工作在半双工模式下，对应的资源为半双工时频资源，全双工设备在半双工时频资源上仅发送或接收信号。
应注意，时频资源可以是泛指通信资源，例如时频资源可以是指具有时间和频率两个维度的通信资源，本发明实施例并不对时频资源的最小单位作限定，例如，时频资源的最小单位在时间上可以是子帧、帧、时隙等，在频率上可以资源块(Resource Block，RB)、子载波、资源单元(Resource Element，RE)、子频带或整个工作频带等。
具体地，第一设备采用上行传输功率向第二设备发送信号，上行传输功率可以是根据第二设备的自干扰补偿量和第一设备的上行开环功率参数确定的功率。第一设备的上行开环功率参数可以为物理层上行控制信道(Physical Uplink Control CHannel，PUCCH)开环功率或者物理层上行共享信道(Physical Uplink Shared Channel，PUSCH)的开环功率。应理解，上行传输功率可以是由第二设备根据第一设备的上行开环功率参数和第二设备的自干扰补偿量确定的功率，也可以是由第一设备根据第一设备的上行开环功率参数和第二设备的自干扰补偿量确定的功率，或者，上行传输功率为第一设备的最大发送功率。
因此，本发明实施例通过第一设备采用上行传输功率是根据第二设备的自干扰补偿量确定的功率，或者上行传输功率为第一设备的最大发送功率的功率向工作在全双工模式下的第二设备发送上行信号，由于，本发明实施例通过第二设备的自干扰补偿量来降低第二设备的自干扰残留量对上行信号接收的不利影响，或第一设备采用最大发送功率发送上行信号来消除第二设备的自干扰残留量对上行信号接收的不利影响，因此，本发明实施例能够消除或降低第二设备的自干扰残留量对上行信号接收的不利影响，能够提高上行信号的接收信号噪声比，提升网络性能。
可选地，作为另一实施例，在310中，第一设备获取第二设备发送的功率指示信息，功率指示信息用于指示第二设备的自干扰补偿量；第一设备根据自干扰补偿量和上行开环功率参数确定上行传输功率。
具体地，自干扰补偿量由第二设备根据以下公式确定的：
ΔSI＝10*log10(N+1)dB其中，ΔSI表示自干扰补偿量，N>0，表示自干扰残留功率是噪声功率的倍数。
在第二设备为基站时，基站可以调度所有的子帧(时频资源)用于全双工传输，因此，第一设备在每个上行子帧上都需要在开环参数上增加自干扰补偿量，以调整第一设备的上行传输功率。具体的讲第一设备在影响各个信道的开环功率参数如LTE中PUCCH信道的开环功率、PUSCH的开环功率的基础上增加自干扰补偿量，即第一设备的上行传输功率为根据第一设备的上行开环功率参数和第二设备的自干扰补偿量之和确定的功率。
或者，在第二设备为中继时，中继可以调度所有的子帧(时频资源)都用于全双工传输，一种情形，第一设备为用户设备，中继处于向基站发送下行信号，从终端接收上行信号的情形。则终端在开环或闭环参数上增加自干扰补偿量，以调节用户设备的上行传输功率。具体的讲第一设备在影响各个信道的开环功率参数如LTE中PUCCH信道的开环功率、PUSCH的开环功率的基础上增加自干扰补偿量，即第一设备的上行传输功率为第一设备的上行开环功率参数和第二设备的自干扰补偿量之和。另一种情形，第一设备为基站，中继处于向用户设备发送下行信号，从基站接收上行信号的情形。同样的，基站在开环或闭环参数上增加中继的自干扰残留补偿量，以调整基站的上行发射功率。具体的讲基站在开环或闭环参数PUCCH信道的开环功率、PUSCH的开环功率的基础上增加自干扰残留偏移量，即第一设备的上行传输功率为根据第一设备的上行开环功率参数和第二设备的自干扰补偿量之和确定的功率。
例如，LTE的上行功控是根据开环功控加上闭环修正的方式。
例如PUSCH的i子帧的功率定义为
Figure PCTCN2014095666-appb-000001
其中PCMAX,c(i)表示终端的最大发射功率；MPUSCH,c(i)表示基于上行授权分配的RB数；PO_PUSCH,c(j)表示开环功率参数；αc(j)表示路损因子；PLc下行路损估计量；ΔTF,c(i)传输方式补偿量；fc(i)表示功控动态偏移；
其中j的取值为0、1和2，分别表示基于半静态调度，动态调度和随机接入的上行传输。
PO_PUSCH,c(0)＝PO_NOMINAL_PUSCH,c(0)+PO_UE_PUSCH,c(0)
PO_PUSCH,c(1)＝PO_NOMINAL_PUSCH,c(1)+PO_UE_PUSCH,c(1)
PO_NOMINAL_PUSCH,c(2)＝PO_PRE+ΔPREAMBLE_Msg3
PO_NOMINAL_PUSCH,c(j)是由高层信令指示，对特定小区的参数，广播给终端。PO_UE_PUSCH,c(j)是由RRC信令配置，针对特定UE的项。PO_PRE和ΔPREAMBLE_Msg3是针对随机接入的高层参数。
当PUSCH和PUCCH同传上行信号时，
Figure PCTCN2014095666-appb-000002
其中
Figure PCTCN2014095666-appb-000003
为i子帧中PUCCH的功率。
其中PO_PUSCH,c(j)受到自干扰残留量的影响，从而影响PPUSCH,c(i)
考虑了基站的自干扰补偿量ΔSI(j)后发射功率公式修改为
Figure PCTCN2014095666-appb-000004
或
Figure PCTCN2014095666-appb-000005
高层信令：
由于PO_NOMINAL_PUSCH,c(j)是由高层信令广播给终端的，PO_UE_PUSCH,c(j)是由RRC信令配置给终端的。因此ΔSI(j)可以通过携带PO_NOMINAL_PUSCH,c(j)或携带PO_UE_PUSCH,c(j)的信令，或新配置的信令通知给终端。到达补偿开环功率参数的目的。
类似的在PUCCH信道上，PUCCH的i子帧的功率定义为
Figure PCTCN2014095666-appb-000006
其中h(nCQI,nHARQ,nSR)是根据PUCCH格式类型的参数，针对分别用于传输CQI(Channel Quality Indication信道质量指示)，HARQ(Hybrid Automatic Repeat Request，混合自动重传请求)反馈和SR(Scheduling Request调度请求)
PO_PUCCH＝PO_NOMINAL_PUCCH+PO_UE_PUCCH
P0_PUCCH开环功率参数受到自干扰的影响，从而影响到PPUCCH(i)，在考虑自干扰补偿量ΔSI后
Figure PCTCN2014095666-appb-000007
类似的P0_PUCCH也可以通过多种信令携带。因此ΔSI可以通过携带PO_NOMINAL_PUCCH或携带PO_UE_PUCCH的信令，或新配置的信令通知给终端。到达补偿开环功率参数的目的。
另外当全双工基站的邻居基站也处于全双工的模式时，造成即使没有自干扰，基站也比半双工模式多收到基站间的干扰，因此造成开环功率参数在两种情况下不同，分别用于半双上行子帧或基站全双工模式工作时的上行子帧。基站需要将两套开环功率参数通知给终端，终端将自干扰补偿量补偿在基站全双工模式工作时的上行子帧的开环功率参数上。
进一步的，作为另一实施例，上行开环功率参数包括第一上行开环功率参数或第二上行开环功率参数，在310中，第一设备根据自干扰补偿量和第一上行开环功率参数确定上行传输功率；或者在310中，第一设备根据自干扰补偿量和第二上行开环功率参数确定上行传输功率。
换句话说，第二设备可以为第一设备配置两套上行开环功率参数，分别为第一上行开环功率参数和第二上行开环功率参数。在不同的时频资源上基站可以根据不同的上行开环功率参数和自干扰补偿量来确定上行传输功率。
可替代地，作为另一实施例，在310中，第一设备获取第二设备发送的功率指示信息，功率指示信息用于指示上行传输功率。
换句话说，第二设备直接确定出第一设备的上行传输功率，通过功率指示信息将上行传输功率发送给第一设备，第一设备直接使用该上行传输功率发送上行信号即可。无需第一设备进行其他的计算。
具体而言，在全双工时频资源上发送上行信号的功率是第二设备根据第二设备的自干扰补偿量确定的功率，该上行传输功率为根据第一设备的上行开环功率参数和第二设备的自干扰补偿量之和确定的功率。
可选地，作为另一实施例，本发明实施例方法还包括：第一设备获取第二设备发送的指示第二功率的信息；第一设备在第二时频资源上采用第二功率向工作在半双工模式下的第二设备发送上行信号。
第二时频资源可以是半双工时频资源，应注意，当全双工时频资源的划分以子帧为单位，则全双工时频资源与全双工子帧等价(表示相同意思)， 全双工时频资源可以用全双工子帧来替代。
应理解，半双工时频资源表示第二设备在该资源上只能承载上行业务或者只能承载下行业务。不同于全双工时频资源，在全双工时频资源上第二设备既可以承载有上行业务也可以承载有下行业务。
具体地，第一设备在半双工时频资源上发送上行信号的功率可以无需考虑第二设备的自干扰补偿量确定的功率，由第二设备直接确定第二功率，然后第二设备告知第一设备，第二上行传输功率可以为根据第一设备的上行开环功率参数确定的功率。
换句话说，可以分两种情况来进行说，第一种情况，第一设备在第一时频资源上发送上行信号，另一种情况为第一设备在第二时频资源上发送上行信号。两种情况对应两种不同的功率调整参数。其中，第一时频资源可以是全双工时频资源，第二资源可以是半双工时频资源。
具体而言，当第二设备为基站时，基站可以调度一部分子帧处于全双工传输，仍然保留部分子帧资源用于半双工上行传输。由于半双工上行传输和全双工传输中上行传输所受到的干扰不同，因此，需要采用两套不同的功率调整参数，分别处理半双工上行传输和全双工传输中上行传输的功率控制。
在全双工时频资源上采用上行传输功率向第二设备发送上行信号；第一设备在半双工时频资源上采用第二功率向第二设备发送上行信号。
由于，全双工子帧中，受到的干扰水平完全和半双工子帧不同。在全双工上行子帧中，不仅受到自干扰信号残留量的干扰，还受到邻居站点的下行干扰。因此，不能共用一套功率控制参数，而且全双工时频资源上的功率控制参数中考虑了自干扰残留偏移量。
或者，第二设备为中继时，一种可能的情况，中继处于向基站发送数据，从终端接收数据的状态。如果终端发射上行数据的子帧资源中，中继部分子帧处于全双工状态，部分子帧仅处于半双工状态(中继接收终端上行信号)。由于半双工上行传输和全双工传输中的上行传输所受到的干扰不同，因此，中继可以采用两套不同的功率调整参数，分别处理半双工上行传输和全双工传输中上行传输的功率控制，即第一设备在全双工时频资源上采用上行传输功率向第二设备发送上行信号；第一设备在半双工时频资源上采用第二功率向第二设备发送其它上行信号。另一种可能的情况，中继处于向用户设备发送数据，从基站接收数据的的情况与上述情况类似，为避免重复不再赘述。
可选地，作为另一实施例，第一时频资源用于第三设备接收第二设备发送的下行信号，第一设备和第三设备是第二设备预先确定的第一设备和第三设备间的干扰小于预设阈值的一对设备。
换句话说，第一设备为第一终端对中的第一终端，第一终端对包括第一终端和第二终端，第一终端对为第一终端组和第二终端组构成的所有终端对中的终端间干扰小于预设阈值的终端对，第二终在与第一终端向第二设备发送上行信号的全双工时频资源上接收第二设备发送的下行信号。
具体地，第一设备在全双工时频资源发送上行信号之前，终端在该半双工上行传输子帧中发送上行控制信号，或上行数据信号，或上行探测信号，在LTE系统中分别对应PUCCH，PUSCH，探测参考信号(Sounding Rsference Signal，SRS)信号。基站将利用这类资源调度包括第一设备的第一终端组中的一部分终端处于发射上行探测信号状态同时，调度包括第三设备第二终端组中的一部分终端处于接收上行探测信号状态。需要说明的是，如果上行和下行采用不同的调制方式，那么第二终端组中的终端必须具有两种不同的调制方式的收发能力，如LTE中上行采用(单载波频分多址接入(Single-carrier Frequency-Division Multiple Access，SC-FDMA)调制，而下行采用正交频分多址(Orthogonal Frequency Division Multiplexing，OFDM)调制。第二终端组中的终端需要具有解SC-FDMA调制的能力。处于接收的终端(第二终端组中的一部分终端)测量来自第二设备范围内的其他终端的终端间干扰水平。因此有部分终端的测量被安排在上行资源上，并且基站为了辅助终端进行干扰测量，在上行探测信号中携带发送SRS的信息，并且第二设备预留出上报测量用户间干扰信息的资源。基站在调度全双工子帧时，选择干扰小于预设阈值的一对设备(第一设备和第三设备)分别在同一时频资源上发送上行信号和接收下行信号。
可选地，作为另一实施例，应用于FDD系统中的下行频段中，第一设备和第三设备之间的干扰是通过第二设备在下行频段中设备的半双工上行时频资源测量的。
具体地，为了测量自干扰残留情况，基站或中继必须在上行频段中划分出一部分资源作为半双工下行资源，用于测量自干扰残留量。并且通知给终端或基站和终端。和TDD中设计一致，这种下行资源不需要每个帧都有，为了减少终端或基站和终端接收在不同频段上的切换，将上行频段中下行资 源时分或频分的用于自干扰测量和通知自干扰补偿量参数的信道。
可选地，作为另一实施例，本发明实施例还包括第一设备接收第二设备根据第一发射参数在全双工时频资源上发送的第一下行信号，其中，第一发射参数使得第二设备与第二设备的临近站点间的干扰小于预设干扰阈值；
第一设备接收第二设备根据第二发射参数在半双工时频资源上发送的第二下行信号。
具体地，第二设备可以为基站。第二设备发送下行信号时采用两套传输参数，包括第一发射参数和第二发射参数。第一发射参数可以用于全双工设备(第二设备)工作在全双工子帧的传输参数，另外一类用于全双工设备工作在半双工子帧的传输参数。
应理解，发射参数可以包括发射功率、天线下倾角、传播模型、基站天线高度等参数。
如果所有的子帧都用于全双工传输，那么基站(第二设备)的下行覆盖不能保证，因此为了保证基站的覆盖，基站可能需要保留部分的子帧用于半双工下行传输。而且如果基站半双工下行和全双工子帧中下行采用相同的发射参数会对邻居上行接收产生很大的干扰，因此，基站在下行需要采用和半双工下行子帧采用不同的下行参数。
基站需要将发射功率，下倾角通过小区间距，传播模型，基站天线高度等参数提前计算最大值，为了减少基站间干扰对上行数据接收的干扰。在全双工子帧发射过程中不能超过上述最大值。
应理解，上述实施例中，以第一设备可以在某个全双工时频资源或半双工时频资源上发送上行信号，并且第一设备还可以在另一全双工时频资源或半双工时频资源上接收第二设备的下行信号的例子举例说明的，应注意，第一设备可以某个全双工时频资源或半双工时频资源上发送上行信号，但是在另一全双工时频资源或半双工时频资源上接收第二设备的下行信号的设备也可以不是第一设备，为其他的设备，本发明实施例并不对此做限定。
进一步地，作为另一实施例，本发明实施例方法还可以包括：
第一下行信号为采用第一发射参数发送的小区特定参考信号(Cell specific Reference Signal，CRS)，第一设备根据采用第一发射参数发送的CRS进行第一设备与第二设备间与CRS相关的测量；
第二下行信号为采用第二发射参数发送的CRS，第一设备根据采用第二 发射参数发送的CRS进行第一设备与第二设备间与CRS相关的测量。
换句话说，第一设备根据接收到的第二设备采用第一发射参数发送的小区特定参考信号CRS进行第一设备与第二设备间与CRS相关的测量；第一设备根据接收到的第二设备采用第二发射参数发送的CRS进行第一设备与第二设备间与CRS相关的测量。
具体地，由于半双工下行子帧和全双工子帧中第二设备的下行信号采用的不同的下行参数，因此和半双工下行子帧中CRS(Cell specific Reference Signal小区特定的参考信号)相关的测量，都不能在全双工子帧中进行或平滑。如路损测量，参考信号接收功率(Reference Signal Received Power，RSRP)和参考信号接收质量(Reference Signal Received Qualify，RSRQ)的测量。
例如在半双工系统中，终端通过基站发送的CRS进行路损测量，而CRS的发射功率是通过高层信令通知给终端，终端根据接收到的CRS功率和基站通知给终端的功率差计算路损。但是基站处于全双工时频资源内可能没有CRS，或者有CRS采用的功率和半双工时频资源内的功率不同。如果两类子帧中的测量如果在子帧间平滑，会造成估计错误。对于RSRP和RSRQ情况类似。因此，本发明实施例针对两种不同的时频资源(全双工时频资源和半双工时频资源)上分别与CRS相关的测量，不进行子帧集合间平滑。
应理解，上述实施例中，以第一设备可以某个全双工时频资源或半双工时频资源上发送上行信号，并且第一设备还可以在另一全双工时频资源或半双工时频资源上接收第二设备的下行信号的例子举例说明的，应注意，第一设备可以某个全双工时频资源或半双工时频资源上发送上行信号，但是在另一全双工时频资源或半双工时频资源上接收第二设备的下行信号的设备也可以不是第一设备，可以为基站调度的另一个属于下行接收的设备，本发明实施例并不对此做限定。因此，当第一设备接收下行信号时可以由第一设备测量第一设备与第二设备间的CRS相关的测量，当由其他设备接收第二设备的下行信号时，由其他设备进行CRS相关的测量。
可选地，作为另一实施例，第一设备为第四设备中的设备，其中，第四设备包括至少一个设备，第四按设备的信号与干扰加噪声比(Signal to Interference plus Noise Ratio，SINR)大于预设阈值。
具体地，第二设备在调度全双工子帧时，调度SINR大于预设阈值的设备接收下行信号。其中SINR可以通过终端上报的信道质量参数(Channel  quality indication，CQI)反映。
在半双工通信系统中，基站通过终端反馈的信道质量参数(Channel quality indication，CQI)调整终端的MCS(Modulation and coding scheme)等级。而基站工作在全双工情况下，部分半双工的终端分别处于接收和发射状态，因此终端间干扰会使得下行接收的情况恶化。如果调度SINR较低的终端，那么终端在受到处于上行发射的终端的干扰时，SINR进一步恶化，导致终端无法解调下行数据。因此选择SINR较大，降低编码调制等级(Modulation coding scheme，MCS)，可以起到抗用户间干扰的作用。
另外，第二设备在调度全双工子帧时，可以调度发射功率余量(Power Headroom，PH)大于预设余量阈值的设备发送上行信号。具体地，在半双工通信系统中，基站通过终端反馈的上行功率余量报告(Power Headroom Report，PHR)了解终端的PH。当PH高，说明终端可以采用更大的发射功率发射上行信号，用来补偿自干扰的影响。
应理解，在较佳实施例中，第二设备在调度全双工子帧时，可以调度SINR大于预设阈值或信道质量指示(Channel Quality Indicator，CQI)大于预设信道质量阈值的设备接收下行信号。第二设备在调度全双工子帧时，可以调度PH大于预设阈值的设备发送上行信号。
上文中，结合图3从第一设备的角度详细描述了本发明实施例的传输信号的方法，下面将结合图4从第二设备的角度描述本发明实施例的传输信号的方法。
图4是根据本发明另一实施的传输信号的方法的示意性流程图。图4的方法由第二设备执行，应用于图1场景中，第二设备可以是基站，第一设备可以是用户设备。应用于图2场景中，第二设备可以是中继，第一设备可以是基站或用户设备。
应理解，图4和图3的区别在于，图4是从第二设备的角度描述的本发明实施例的传输信号的方法，图3是从第一设备的角度描述的本发明实施例的传输信号的方法，图4中的传输信号的方法与图3中的传输信号的方法相对应，图4传输信号的方法的相关描述可参见针对图3方法的描述，为避免重复，下文中适当省略详细描述。
具体地，如图4所示的方法包括：
410，第二设备生成功率指示信息，功率指示信息用于第一设备根据功 率指示信息确定向工作在全双工模式下的第二设备发送上行信号的上行传输功率，上行传输功率是根据第二设备的自干扰补偿量确定的功率，或者上行传输功率为第一设备的最大发送功率。
420，第二设备向第一设备发送功率指示信息。
430，第二设备接收第一设备采用上行传输功率在第一时频资源上发送的上行信号。
具体地，第二设备为具有同时同频发送信号和接收信号的能力的全双工设备。例如，第二设备可以为基站或中继等。
应理解，第一时频资源可以为全双工时频资源，全双工时频资源表示在该资源上既同时承载有上行业务和下行业务。第二设备在该全双工时频资源上也可以向另外的一个设备发送下行信号。也就是说第二设备在该全双工时频资源上即可以接收第一设备发送的上行信号，还可以向另外一个设备发送信号。
需要说明的一点是，全双工设备是指具有同时同频收发信号的能力的设备，全双工设备可以有多种工作模式，例如全双工模式和半双工模式等，全双工设备可以工作在全双工模式下，也可以回退(切换)到半双工模式下。全双工设备可以根据系统的中干扰，业务，用户分布等情况确定工作在全双工模式下还是半双工模式下。
其中，全双工设备工作在全双工模式下，也可以处于两种状态，一种是全双工通信，对应的资源为全双工时频资源，即全双工设备在全双工时频资源上即发送数据又接收数据。另外一种为全双工监听，对应的资源为半双工下行资源，即全双工设备在半双工下行资源上发送数据，接收链路仅作为监听或测量干扰，并不解调接收数据。全双工设备工作在半双工模式下，对应的资源为半双工时频资源，全双工设备在半双工时频资源上仅发送或接收信号。
应注意，时频资源可以是泛指通信资源，例如时频资源可以是指具有时间和频率两个维度的通信资源，本发明实施例并不对时频资源的最小单位作限定，例如，时频资源的最小单位在时间上可以是子帧、帧、时隙等，在频率上可以是RB、子载波、RE、子频带或整个工作频带等。
具体地，第一设备采用上行传输功率向第二设备发送信号，上行传输功率可以是根据第二设备的自干扰补偿量和第一设备的上行开环功率参数确 定的功率。第一设备的上行开环功率参数可以为PUCCH开环功率或者PUSCH的开环功率。应理解，上行传输功率可以是由第二设备根据第一设备的上行开环功率参数和第二设备的自干扰补偿量之和确定的功率，也可以是由第一设备根据第一设备的上行开环功率参数和第二设备的自干扰补偿量之和确定的功率，或者，上行传输功率为第一设备的最大发送功率。
因此，本发明实施例，通过第二设备生成指示上行传输功率的功率指示信息，并向第一设备发送该功率指示信息，接收第一设备采用上行传输功率在第一时频资源上发送的上行信号。由于，本发明实施例通过第二设备的自干扰补偿量来降低第二设备的自干扰残留量对上行信号接收的不利影响，或第一设备采用最大发送功率发送上行信号来消除第二设备的自干扰残留量对上行信号接收的不利影响，因此，本发明实施例能够消除或降低第二设备的自干扰残留量对上行信号接收的不利影响，能够提高上行信号的接收信号噪声比，提升网络性能。
可选地，作为另一实施例，在410之前，本发明实施方法还包括第二设备确定第二设备的自干扰补偿量，
其中，在410中，第二设备根据自干扰补偿量生成功率指示信息。
例如，第二设备根据以下公式确定第二设备的自干扰补偿量
ΔSI＝10*log10(N+1)dB
其中，ΔSI表示自干扰补偿量，N>0，表示自干扰残留功率是噪声功率的倍数。
具体地，第二设备首先确定第二设备的自干扰补偿量，并根据自干扰补偿量生成成功率指示信息，功率指示信息用于第一设备根据功率指示信息确定向第二设备发送上行信号的上行传输功率，第二设备接收第一设备采用上行传输功率发送的上行信号。例如，上行传输功率为第一设备的上行开环功率参数和第二设备的自干扰补偿量之和，因此，第一设备采用上行传输功率发射信号能够消除或降低第二设备信号的自干扰残留对上行信号接收的不利影响。
因此，本发明实施例通过第二设备确定第二设备的自干扰补偿量，根据自干扰补偿量生成功率指示信息，向第一设备发送功率指示信息，最后接收第一设备采用上行传输功率发送的上行信号。由于本发明实施例通过第二设备的自干扰补偿量来降低第二设备的自干扰残留量对上行信号接收的不利 影响，或第一设备采用最大发送功率发送上行信号来消除第二设备的自干扰残留量对上行信号接收的不利影响，因此，本发明实施例能够消除或降低第二设备的自干扰残留量对上行信号接收的不利影响，能够提高上行信号的接收信号噪声比，提升网络性能。
可选地，作为另一实施例，在410中，所第二设备根据自干扰补偿量生成功率指示信息，其中，功率指示信息用于指示自干扰补偿量，以便于第一设备根据自干扰补偿量和上行开环功率参数确定上行传输功率。
在第二设备为基站时，基站可以调度所有的子帧(时频资源)用于全双工传输，因此，第一设备在每个上行子帧上都需要在开环参数上增加自干扰补偿量，以调整第一设备的上行传输功率。具体的讲第一设备在影响各个信道的开环功率参数如LTE中PUCCH信道的开环功率、PUSCH的开环功率的基础上增加自干扰补偿量，即第一设备的上行传输功率为根据第一设备的上行开环功率参数和第二设备的自干扰补偿量之和确定的功率。
或者，在第二设备为中继时，中继可以调度所有的子帧(时频资源)都用于全双工传输，一种情形，第一设备为用户设备，中继处于向基站发送下行信号，从终端接收上行信号的情形。则终端在开环或闭环参数上增加自干扰补偿量，以调节用户设备的上行传输功率。具体的讲第一设备在影响各个信道的开环功率参数如LTE中PUCCH信道的开环功率、PUSCH的开环功率的基础上增加自干扰补偿量，即第一设备的上行传输功率为第一设备的上行开环功率参数和第二设备的自干扰补偿量之和。另一种情形，第一设备为基站，中继处于向用户设备发送下行信号，从基站接收上行信号的情形。同样的，基站在开环或闭环参数上增加中继的自干扰残留补偿量，以调整基站的上行发射功率。具体的讲基站在开环或闭环参数PUCCH信道的开环功率、PUSCH的开环功率的基础上增加自干扰残留偏移量，即第一设备的上行传输功率为根据第一设备的上行开环功率参数和第二设备的自干扰补偿量之和确定的功率。
例如，LTE的上行功控是根据开环功控加上闭环修正的方式。
例如PUSCH的i子帧的功率定义为
Figure PCTCN2014095666-appb-000008
其中PCMAX,c(i)表示终端的最大发射功率；MPUSCH,c(i)表示基于上行授权分 配的RB数；PO_PUSCH,c(j)表示开环功率参数；αc(j)表示路损因子；PLc下行路损估计量；ΔTF,c(i)传输方式补偿量；fc(i)表示功控动态偏移；
其中j的取值为0、1和2，分别表示基于半静态调度，动态调度和随机接入的上行传输。
PO_PUSCH,c(0)＝PO_NOMINAL_PUSCH,c(0)+PO_UE_PUSCH,c(0)
PO_PUSCH,c(1)＝PO_NOMINAL_PUSCH,c(1)+PO_UE_PUSCH,c(1)
PO_NOMINAL_PUSCH,c(2)＝PO_PRE+ΔPREAMBLE_Msg3
PO_NOMINAL_PUSCH,c(j)是由高层信令指示，对特定小区的参数，广播给终端。PO_UE_PUSCH,c(j)是由RRC信令配置，针对特定UE的项。PO_PRE和ΔPREAMBLE_Msg3是针对随机接入的高层参数。
当PUSCH和PUCCH同传上行信号时，
Figure PCTCN2014095666-appb-000009
其中
Figure PCTCN2014095666-appb-000010
为i子帧中PUCCH的功率。
其中PO_PUSCH,c(j)受到自干扰残留量的影响，从而影响PPUSCH,c(i)
考虑了基站的自干扰补偿量ΔSI(j)后发射功率公式修改为
Figure PCTCN2014095666-appb-000011
或
Figure PCTCN2014095666-appb-000012
高层信令：
由于PO_NOMINAL_PUSCH,c(j)是由高层信令广播给终端的，PO_UE_PUSCH,c(j)是由RRC信令配置给终端的。因此ΔSI(j)可以通过携带PO_NOMINAL_PUSCH,c(j)或携带PO_UE_PUSCH,c(j)的信令，或新配置的信令通知给终端。到达补偿开环功率参数的目的。
类似的在PUCCH信道上，PUCCH的i子帧的功率定义为
Figure PCTCN2014095666-appb-000013
其中h(nCQI,nHARQ,nSR)是根据PUCCH格式类型的参数，针对分别用于传输 CQI(Channel Quality Indication信道质量指示)，HARQ(Hybrid Automatic Repeat Request，混合自动重传请求)反馈和SR(Scheduling Request调度请求)
PO_PUCCH＝PO_NOMINAL_PUCCH+PO_UE_PUCCH
P0_PUCCH开环功率参数受到自干扰的影响，从而影响到PPUCCH(i)，在考虑自干扰补偿量ΔSI后
Figure PCTCN2014095666-appb-000014
类似的P0_PUCCH也可以通过多种信令携带。因此ΔSI可以通过携带PO_NOMINAL_PUCCH或携带PO_UE_PUCCH的信令，或新配置的信令通知给终端。到达补偿开环功率参数的目的。
另外当全双工基站的邻居基站也处于全双工的模式时，造成即使没有自干扰，基站也比半双工模式多收到基站间的干扰，因此造成开环功率参数在两种情况下不同，分别用于半双上行子帧或基站全双工模式工作时的上行子帧。基站需要将两套开环功率参数通知给终端，终端将自干扰补偿量补偿在基站全双工模式工作时的上行子帧的开环功率参数上。
可替代地，作为另一实施例，在410中，第二设备根据自干扰补偿量生成功率指示信息，其中，功率指示信息用于指示上行传输功率。
换句话说，第二设备直接确定出第一设备的上行传输功率，通过功率指示信息将上行传输功率发送给第一设备，第一设备直接使用该上行传输功率发送上行信号即可。无需第一设备进行其他的计算。
具体的，可以分两种情况来进行说，第一种情况，第一设备在全双工时频资源上发送上行信号，另一种情况为第一设备在半双工时频资源上发送上行信号。两种情况对应两种不同的功率参数。具体而言，在全双工时频资源上发送上行信号的功率是第二设备根据第二设备的自干扰补偿量确定的功率，该上行传输功率为第一设备的上行开环功率参数和第二设备的自干扰补偿量之和。在半双工时频资源上发送上行信号的功率可以无需考虑第二设备的自干扰补偿量确定的功率，由第二设备直接确定，然后第二设备告知第一设备该上行传输功率可以为第一设备的上行开环功率参数。
因此，对应第一种情形，作为另一实施例，在430中，第二设备在全双工时频资源上接收第一设备采用上行传输功率发送的上行信号；
对应第二种情况，本发明实施例方法还包括：第二设备生成指示第二功率的信息；第二设备向第一设备发送发送指示第二功率的信息，以便于工作在半双工模式下的第二设备在第二时频资源上接收第一设备采用第二功率发送的其它上行信号。
应理解，第一时频资源可以为全双工时频资源，第二时频资源可以为半双工时频资源。
具体而言，当第二设备为基站时，基站可以调度一部分子帧处于全双工传输，仍然保留部分子帧资源用于半双工上行传输。由于半双工上行传输和全双工传输中上行传输所受到的干扰不同，因此，需要采用两套不同的功率调整参数，分别处理半双工上行传输和全双工传输中上行传输的功率控制。
在全双工时频资源上采用上行传输功率向向第二设备发送上行信号；第一设备在半双工时频资源上采用第二功率向第二设备发送上行信号。
由于，全双工子帧中，受到的干扰水平完全和半双工子帧不同。在全双工上行子帧中，不仅受到自干扰信号残留量的干扰，还受到邻居站点的下行干扰。因此，不能共用一套功率控制参数，而且全双工时频资源上的功控控制参数中考虑了自干扰残留偏移量。
或者，第二设备为中继时，一种可能的情况，中继处于向基站发送数据，从终端接收数据的状态。如果终端发射上行数据的子帧资源中，中继部分子帧处于全双工状态，部分子帧仅处于半双工状态(接收终端上行数据)。由于半双工上行传输和全双工传输中上行传输所受到的干扰不同，因此，可以采用两套不同的功率调整参数，分别处理半双工上行传输和全双工传输中上行传输的功率控制，即在全双工时频资源上采用上行传输功率向向第二设备发送上行信号；第一设备在半双工时频资源上采用第二功率向第二设备发送其它上行信号。另一种可能的情况，中继处于向用户设备发送数据，从基站接收数据的的情况与上述情况类似，为避免重复不再赘述。
可选地，作为另一实施例，应用于FDD系统中的上行频段中，在第二设备确定第二设备的自干扰补偿量之前，本发明实施例方法还包括：
第二设备在上行频段中设置半双工下行时频资源，半双工下行时频资源用于测量第二设备的自干扰补偿量。
为了测量自干扰残留情况，基站或中继必须在上行频段中增加半双工下行资源，用于测量自干扰残留量。并且通知给终端或基站和终端。和TDD 中设计一致，这种下行资源不需要每个帧都有。
为了减少终端或基站和终端接收在不同频段上的切换，将上行频段中下行资源时分或频分的用于自干扰测量和通知自干扰残留参数的信道。
并且基站和终端具有在FDD上行频段接收能力。进一步，鉴于终端低成本的设计考虑，终端在FDD上行频段为半双工工作模式。因此，预留上下行切换时间。
进一步地，作为另一实施例，在FDD上行频段的上行频段中设置半双工下行时频资源的周期大于或等于一个无线帧。
换句话说，并不是每一个FDD上行频段的上行频段中的帧中设置半双工下行时频资源。可以在FDD上行频段的上行频段中的每个帧上设置半双工下行时频资源或者间隔几个帧设置半双工下行时频资源。
具体地，为了测量自干扰残留情况，基站或中继必须在上行频段中划分出一部分资源作为半双工下行资源，用于测量自干扰残留量。并且通知给终端或基站和终端。和TDD中设计一致，这种下行资源不需要每个帧都有，为了减少终端或基站和终端接收在不同频段上的切换，将上行频段中下行资源时分或频分的用于自干扰测量和通知自干扰补偿量参数的信道。
可选地，作为另一实施例，第一时频资源用于第三设备接收第二设备发送的下行信号，第一设备和第三设备是第二设备预先确定的第一设备和第三设备间的干扰小于预设阈值的一对设备。
换句话说，第一设备为第一终端对中的第一终端，第一终端对包括第一终端和第二终端，第一终端对为第一终端组和第二终端组构成的所有终端对中的终端间干扰小于预设阈值的终端对，第二终在与第一终端向第二设备发送上行信号的全双工时频资源上接收第二设备发送的下行信号。
具体地，第一设备在全双工时频资源发送上行信号之前，终端在该半双工上行传输子帧中发送上行控制信号，或上行数据信号，或上行探测信号，在LTE系统中分别对应PUCCH，PUSCH，SRS信号。基站将利用这类资源调度包括第一设备的第一终端组中的一部分终端处于发射上行探测信号状态同时，调度包括第三设备第二终端组中的一部分终端处于接收上行探测信号状态。需要说明的是，如果上行和下行采用不同的调制方式，那么第二终端组中的终端必须具有两种不同的调制方式的收发能力，如LTE中上行采用SC-FDMA调制，而下行采用OFDM调制。第二终端组中的终端需要具有解 SC-FDMA调制的能力。处于接收的终端(第二终端组中的一部分终端)测量来自第二设备范围内的其他终端的终端间干扰水平。因此有部分终端的测量被安排在上行资源上，并且基站为了辅助终端进行干扰测量，在上行探测信号中携带发送SRS的信息，并且第二设备预留出上报测量用户间干扰信息的资源。基站在调度全双工子帧时，选择干扰小于预设阈值的一对设备(第一设备和第三设备)分别在同一时频资源上发送上行信号和接收下行信号。
可选地，作为另一实施例，应用于FDD系统中的下行频段中，方法还包括：第二设备在下行频段中设置半双工上行时频资源，半双工上行时频资源用于测量第一设备与第三设备间的干扰。
具体地，第二设备为基站时，应用于FDD系统中的下行频段中，第二设备需要在下行频段中设置半双工上行时频资源，半双工上行时频资源用于测量第一设备与第三设备间的干扰。第二设备预先确定第一设备和第三设备是的干扰小于预设阈值，之后，第二设备在全双工时频资源上接收第一设备采用上行传输功率发送的上行信号，在全双工时频资源向第三设备第二设备发送的下行信号。
可选地，作为另一实施例，本发明实施例还包括：
第二设备根据第一发射参数在全双工时频资源上发送第一下行信号，其中，第一发射参数使得第二设备与第二设备的临近站点间的干扰小于预设干扰阈值；
第二设备根据第二发射参数在半双工时频资源上发送第二下行信号。
具体地，第二设备可以为基站。第二设备发送下行信号时采用两套传输参数，包括第一发射参数和第二发射参数。第一发射参数可以用于全双工设备(第二设备)工作在全双工子帧的传输参数，另外一类用于全双工设备工作在半双工子帧的传输参数。
应理解，发射参数可以包括发射功率、天线下倾角、传播模型、基站天线高度等参数。
如果所有的子帧都用于全双工传输，那么基站(第二设备)的下行覆盖不能保证，因此为了保证基站的覆盖，基站可能需要保留部分的子帧用于半双工下行传输。而且如果基站半双工下行和全双工子帧中下行采用相同的发射参数会对邻居上行接收产生很大的干扰，因此，基站在下行需要采用和半双工下行子帧采用不同的下行参数。
基站需要将发射功率，下倾角通过小区间距，传播模型，基站天线高度等参数提前计算最大值，为了减少基站间干扰对上行数据接收的干扰。在全双工子帧发射过程中不能超过上述最大值。
应理解，上述实施例中，以第一设备可以在某个全双工时频资源或半双工时频资源上发送上行信号，并且第一设备还可以在另一全双工时频资源或半双工时频资源上接收第二设备的下行信号的例子举例说明的，应注意，第一设备可以某个全双工时频资源或半双工时频资源上发送上行信号，但是在另一全双工时频资源或半双工时频资源上接收第二设备的下行信号的设备也可以不是第一设备，为其他的设备，本发明实施例并不对此做限定。
进一步地，作为另一实施例，本发明实施例方法还可以包括：
第二设备确定SINR大于预设阈值或CQI大于预设信道质量阈值的第四设备，第四设备包括至少一个设备；第二设备确定PH大于预设余量阈值的第五设备，第五设备包括至少一个设备；第二设备在全双工时频资源上接收第五设备发送的上行信号；
其中，第二设备根据第一发射参数在全双工时频资源上发送第一下行信号，包括：第二设备根据第一发射参数在全双工时频上向第四设备中的至少一个设备发送第一下行信号。
应理解，第五设备可以与第一设备为同一设备，也可以为不同的设备，本发明实施例并不对此作限定。
具体地，第二设备在调度全双工子帧时，调度SINR大于预设阈值的设备接收下行信号。
另外，第二设备可以在调度全双工子帧时，调度PH大于预设余量阈值的第五设备发送上行信号。在半双工通信系统中，基站通过终端反馈的PHR了解终端的PH。当PH高，说明终端可以采用更大的发射功率发射上行信号，用来补偿自干扰的影响。
应理解，在较佳实施例中，第二设备在调度全双工子帧时，可以调度SINR大于预设阈值或CQI大于预设信道质量阈值的设备接收下行信号。本发明实施例并不对此做限定，第二设备在调度全双工子帧时，也可以调度任一设备接收下行信号。
上文中，结合图1至图4详细描述了本发明实施例的传输信号的方法，下面将结合图5至图8详细描述本发明实施例的设备。
图5是根据本发明一个实施例的传输信号的设备的示意框图。应用图1的场景中图5所示的设备500为用户设备，第二设备为基站。应用图2的场景中图5所示的设备500为基站或用户设备，第二设备为中继。如图5所示的设备500包括：确定单元510和第一发送单元520。

因此，本发明实施例通过传输信号的设备采用上行传输功率是根据第二设备的自干扰补偿量确定的功率，或者上行传输功率为设备的最大发送功率的功率向工作在全双工模式下的第二设备发送上行信号，由于，本发明实施例通过第二设备的自干扰补偿量来降低第二设备的自干扰残留量对上行信号接收的不利影响，或设备采用最大发送功率发送上行信号来消除第二设备的自干扰残留量对上行信号接收的不利影响，因此，本发明实施例能够消除或降低第二设备的自干扰残留量对上行信号接收的不利影响，能够提升网络性能。

可选地，作为另一实施例，自干扰补偿量由第二设备根据以下公式确定的：
ΔSI＝10*log10(N+1)dB
其中，ΔSI表示自干扰补偿量，N>0，表示自干扰残留功率是噪声功率的倍数。
应理解，图5所示的设备500能够实现图3和图4所示的方法中由第一设备完成的各个过程，具体可参见图3和图4所示方法的描述，为避免重复，此处不再赘述。
图6是根据本发明另一实施例的传输信号的设备的示意框图。应用图1的场景中图6所示的设备600为基站，第一设备为用户设备。应用图2的场景中图6所示的设备600为中继，第一设备为基站或用户设备。如图6所示的设备600包括：第一生成单元610、第一发送单元620和第一接收单元630。

因此，本发明实施例，通过设备生成指示上行传输功率的功率指示信息，并向第一设备发送该功率指示信息，接收第一设备采用上行传输功率在第一时频资源上发送的上行信号。由于，本发明实施例通过设备的自干扰补偿量来降低设备的自干扰残留量对上行信号接收的不利影响，或第一设备采用最大发送功率发送上行信号来消除第二设备的自干扰残留量对上行信号接收 的不利影响，因此，本发明实施例能够消除或降低第二设备的自干扰残留量对上行信号接收的不利影响，能够提升网络性能。
可选地，作为另一实施例，还包括：第一确定单元，用于确定设备的自干扰补偿量；其中，第一生成单元610根据自干扰补偿量生成功率指示信息。
因此，本发明实施例通过传输信号的设备确定设备的自干扰补偿量，根据自干扰补偿量生成功率指示信息，向第一设备发送功率指示信息，最后接收第一设备采用上行传输功率发送的上行信号。由于本发明实施例通过传输信号的设备的自干扰补偿量来降低自干扰残留量对上行信号接收的不利影响，或第一设备采用最大发送功率发送上行信号来消除设备的自干扰残留量对上行信号接收的不利影响，因此，本发明实施例能够消除或降低设备的自干扰残留量对上行信号接收的不利影响，能够提升网络性能。
可选地，作为另一实施例，第一生成单元610根据自干扰补偿量生成功率指示信息，其中，功率指示信息用于指示自干扰补偿量，以便于第一设备根据自干扰补偿量和上行开环功率参数确定上行传输功率。
可替代地，作为另一实施例，第一生成单元610根据自干扰补偿量生成功率指示信息，其中，功率指示信息用于指示上行传输功率。
可选地，作为另一实施例，该设备还包括：第二生成单元，用于生成指示第二功率的信息；第二发送单元，用于向第一设备发送指示第二功率的信息，以便于工作在半双工模式下的设备在第二时频资源上接收第一设备采用第二功率发送的其它上行信号。

应理解，图6所示的设备600能够实现图3和图4所示的方法中由第二设备完成的各个过程，具体可参见图3和图4所示方法的描述，为避免重复，此处不再赘述。
图7是根据本发明另一实施例的传输信号的设备的示意框图。应用图1的场景中图7所示的设备700为用户设备，第二设备为基站。应用图2的场景中图7所示的设备700为基站或用户设备，第二设备为中继。如图7所示的设备700包括处理器710、存储器720、总线系统730和收发器740。
具体地，处理器710通过总线系统730调用存储在存储器720中的代码，确定上行传输功率；收发器740采用上行传输功率在第一时频资源上向工作在全双工模式下的第二设备发送上行信号，其中，上行传输功率是根据第二设备的自干扰补偿量确定的功率，或者上行传输功率为第一设备的最大发送功率。
因此，本发明实施例通过传输信号的设备采用上行传输功率是根据第二设备的自干扰补偿量确定的功率，或者上行传输功率为设备的最大发送功率的功率向工作在全双工模式下的第二设备发送上行信号，由于，本发明实施例通过第二设备的自干扰补偿量来降低第二设备的自干扰残留量对上行信 号接收的不利影响，或设备采用最大发送功率发送上行信号来消除第二设备的自干扰残留量对上行信号接收的不利影响，因此，本发明实施例能够消除或降低第二设备的自干扰残留量对上行信号接收的不利影响，能够提升网络性能。

可选地，作为另一实施例，自干扰补偿量由第二设备根据以下公式确定的：

具体地，处理器810通过总线系统830调用存储在存储器820中的代码，生成功率指示信息，功率指示信息用于第一设备根据功率指示信息确定向工作在全双工模式下的设备发送上行信号的上行传输功率，上行传输功率是根据设备的自干扰补偿量确定的功率，或者上行传输功率为第一设备的最大发送功率；收发器840向第一设备发送功率指示信息；收发器840接收第一设备采用上行传输功率在第一时频资源上发送的上行信号。
因此，本发明实施例，通过设备生成指示上行传输功率的功率指示信息，并向第一设备发送该功率指示信息，接收第一设备采用上行传输功率在第一时频资源上发送的上行信号。由于，本发明实施例通过设备的自干扰补偿量来降低设备的自干扰残留量对上行信号接收的不利影响，或第一设备采用最大发送功率发送上行信号来消除设备的自干扰残留量对上行信号接收的不利影响，因此，本发明实施例能够消除或降低第二设备的自干扰残留量对上行信号接收的不利影响，能够提升网络性能。
