现有技术中，在长期演进(Long Term Evolution；简称：LTE)增强干扰管理和业务自适应(Enhanced Interference Management and Traffic Adaptation；简称：eIMTA)中，采用了基于子帧集合的双环上行功率控制增强方案，包括开环功率控制增强和闭环功率控制增强，其中，子帧集合包括可变子帧集合和固定子帧集合。另外，不同的子帧集合是由网络侧半静态配置的，由于可变子帧集合会存在UE-UE间的交叉干扰，而固定子帧集合上不存在交叉干扰，因此针对两类不同的子帧集合采用不同的功率控制参数集合。
然而，现有技术中，虽然开环和闭环的功率控制参数由两类子帧集合类型决定，这样能实现根据不同的数据传输业务类型进行子帧配置模式的切换和功率的控制，但是这种功率控制方式下，UE间的交叉干扰的降低仍有提升空间。

演进型基站(Evolved Node B；简称：eNB)主要负责空口侧的无线资源管理、服务质量(Quality of Service；简称：QoS)管理、数据压缩和加密等功能。在核心网侧，eNB主要负责向MME转发控制面信令以及向S-GW转发用户面业务数据。
UE是LTE中通过eNB接入网络侧的设备，例如可以是手持终端、笔记本电脑或是其他可以接入网络的设备。
S1接口是eNB与核心网之间的标准接口。其中eNB通过S1-MME接口与MME连接，用于控制信令的传输；eNB通过S1-U接口与S-GW连接，用于用户数据的传输。其中S1-MME接口和S1-U接口统称为S1接口。

本申请实施例涉及的上行功率控制方法，主要针对的是在通信系统中，如何避免UE与UE之间进行交叉干扰的问题。现有技术中，在LTE eIMTA中，采用基于子帧集合的双环上行功率控制增强方案，包括开环功率控制增强方案和闭环功率控制增强方案，其中，子帧集合包括可变子帧集合和固定子帧集合。由于可变子帧集合会存在UE-UE间的交叉干扰，而固定子帧集合上不存在交叉干扰，因此针对两类不同的子帧集合采用不同的功率控制参数集合。但是，虽然开环和闭环的功率控制参数由两类子帧集合类型决定，这样能实现根据不同的数据传输业务类型进行子帧配置模式的切换和功率的控制，但是在这种功率控制方式，UE之间的交叉干扰仍有提升空间。
因此，本申请实施例提供的上行功率控制方法及装置，旨在进一步降低UE与UE之间进行交叉干扰。
图3为本申请实施例提供的上行功率控制系统的结构示意图，如图3所示，该系统中包括第一UE和至少一个第二UE，本实施例中以包括两个第二UE为例进行说明。其中，第一UE为接收到网络侧下发的上行调度分配(Uplink Grant；简称：UL Grant)的UE，第二UE为接收到网络侧下发的下行调度分配(Downlink Grant；简称：DL Grant)的UE。在实际应用中，被上行调度的第一UE会对相邻小区中处于下行调度的第二UE产生干扰，为了降低该干扰，两个第二UE可以分别在第二时频资源上向第一UE发送第二信号，第一UE可以对这两个第二信号进行叠加形成的第一信号进行测量，并根据测量的结果控制上行功率，以达到降低对相邻小区的第二UE产生的干扰。其中，第一信号例如可以为感知信号，第二信号为两个感知信号进行叠加形成的叠加信号。
具体地，图4为一个时域资源单元的结构示意图，一种可选的方案中，该时域资源单元可以依次包括下行控制区域(用于承载下行控制信息)，下行数据区域和上行控制区域(用于承载上行控制信息)，其中，下行控制区域和下行数据区域之间包括一段时间区域，该时间区域可以用于发送感知信号，其中感知信息为用于测量UE间交叉干扰的信号，因而该时间区域也可称为感知区域(即图中的用于发送第二信号的时域资源)。另一种可选的方案中，该时域资源单元可以依次包括下行控制区域，上行数据区域和上行控制区域，其中，下行控制区域和上行数据区域之间包括一段时间区域，该时间区域用于作为下行控制区域和上行数据区域之间的下/上行切换的保护间隔(GP)，进一步的，该时间区域还可以用于接收感知信号，其中感知信息为用于测量UE间交叉干扰的信号，因而该时间区域也可称为感知区域(即图中的用于测量第一信号的时域资源)。在图3所示的结构示意图的基础上，可以利用信道互异性，由被下行调度的第二UE发送感知信号，由上行调度的第一UE对叠加信号进行测量，获得干扰强度和干扰等级。第一UE可以以在基站侧预先配置的功率控制参数集合中选择的至少一个上行功率控制参数集为基准，根据获得的干扰强度和干扰等级，以相对于预先配置的功率控制参数集合的变化量进行上行功率控制。由于在这种情况下基站侧盲检确定调制与编码策略(Modulation and Coding Scheme；简称：MCS)的复杂 度高，因此，在具体的实现过程中，在本资源时域单元上控制上行功率时，可通过将上行控制信息放在上行数据的前面发送，而功率控制的指示信息可通过上行控制信息进行承载，其中，该指示信息包括相对于预先配置的功率控制参数集合的变化量和MCS等信息。
下面以具体地实施例对本申请的技术方案进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。
图5为本申请上行功率控制方法实施例一的流程示意图。本申请实施例提供了一种上行功率控制方法，该方法可以由任意执行上行功率控制方法的装置来执行，该装置可以通过软件和/或硬件实现。本实施例中，该装置可以集成在UE中。如图5所示，本实施例的方法可以包括：
步骤501：第一UE在第一时频资源上对第一信号进行测量，获得测量结果；第一信号为至少一个第二UE在第二时频资源上发送的第二信号进行叠加形成的信号；第一时频资源的时域资源属于第一时域资源单元。
其中，第一UE为接收到网络侧设备下发的上行调度分配的UE，第二UE为接收到网络侧设备下发的下行调度分配的UE，第一时域资源单元为当前时域资源单元。值得注意的是，时域资源单元可以是无线通信技术，如LTE或新无线接入技术(New RAT；简称：NR)中的一种时域资源调度和分配单元，包括但不限于子帧、时隙(slot)，短时隙(mini-slot)，传输时间间隔(Transmit Time Interval；简称：TTI)等。另外，时频资源包括时域和频域两个维度的资源，其中，时域资源可包含N个符号资源单元，其中，N为正整数，频域资源指以资源块(Resource Block；RB)或资源单元(Resource Element；简称：RE)为基本分配单位的频段资源。
在本实施例中，至少一个第二UE在第二时频资源上向第一UE发送第二信号，至少一个第二信号相互叠加，即可形成第一信号。第一UE在第一时频资源上对叠加后的第一信号进行测量，以获得测量结果。其中，第一时频资源可以是预定义的，也可以是由网络侧设备通过下发控制信息进行指示的，而控制信息可以是动态控制信息，例如上行调度分配信息，也可以是半静态控制信息，例如无线资源控制(Radio Resource Control；简称：RRC)信令或广播消息等。类似地，第二时频资源可以是预定义的，也可以是由网络侧设备通过下发控制信息进行指示的，而控制信息可以是动态控制信息，例如下行调度分配，也可以是半静态控制信息，如RRC信令或广播消息等。对于第一时频资源和第二时频资源的具体确定方式，本实施例在此不作限制。
下面以第二信号为第二UE发送的感知信号为例，详细说明第二UE发送感知信号的过程。
第二UE在发送感知信号时，需要确定发送感知信号的时域资源单元、频域资源、符号资源和定时等信息。在具体的实现过程中，第二UE可以根据静态指示方式确定需要发送感知信号的时域资源单元，比如所有调度为下行的时域资源单元或除固定时域资源单元外所有调度为下行的时域资源单元，也可以根据半静态指示方式确定需要发送感知信号的时域资源单元，例如通过RRC信令确定，还可以根据动态指示方式确定需要发送感知信号的时域资源单元，对于时域资源单元的具体的确定方式，本实施例在此不作限制。
需要进行说明的是，时域资源单元例如可以为子帧，参照图4所示，上行子帧包括下行控制信息、第一UE用于测量第一信号的时域资源、上行数据区域和上行控制信息。其中，第一UE可以根据下行控制信息中的子帧类型指示信息指示子帧类型，即确定为DL还是UL，时域资源的大小可以为N个符号，N为大于或等于1的整数，上行数据区域可以用于上行数据信息的传输，上行控制信息可以用于上行控制信息的传输。
继续参照图4所示，下行子帧包括下行控制信息、第二UE用于发送第二信号的时域资源、下行数据区域和上行控制信息。其中，下行控制信息的结构与上行子帧中类似，此处不再赘述。时域资源的大小可以为N个符号，N为大于或等于1的整数，下行数据区域可以用于下行数据信息的传输，上行控制信息可以用于上行控制信息的传输。另外，在下行数据区域和上行控制信息之间还可以包括一段保护间隔。
另外，第二UE可以根据预设的定时偏置、控制信道资源信息和感知信号的参数，确定发送感知信号的符号资源和定时。其中，感知信号的参数例如可以为时域资源可以占一个符号的时间间隔，如子载波间隔是15kHz时，一个符号的持续时间是66.7us。举例来说，图6为确定感知信号的符号资源和定时的示意图，如图6所示，控制信道资源信息，即下行控制信道的符号个数(可以通过下行控制信息指示)，定时偏置为感知信号相对于下行控制信息的时间偏移量，例如：相对于下行控制信道的第一个符号起始位置的时间偏移量或者相对于下行控制信道的最后一个符号结束位置的的时间偏移量，感知信号的参数包括感知信号的符号所占用的时间长度的信息，符号资源指示了第二UE发送感知信号的时域资源，如图6中所示，根据定时偏置、控制信道资源信息和感知信号的参数，即可确定出感知信号的起始定时和结束定时，继而可以确定出发送感知信号的时域资源。
另外，感知信号的频域资源可以由第二UE分配的物理资源模块(Physical Resource Block；简称：PRB)编号指示，也可以位于预定义的频域资源上。
可选地，参见图7为对第一信号进行测量的流程示意图，上述步骤501具体可以包括：
步骤5011、第一UE确定接收第一信号的时域资源单元、频域资源、符号资源和定时；该频域资源由第一UE被调度分配的PRB的编号指示，或频域资源位于预定义的频域资源上；该时域资源单元用于指示网络侧设备在时域上调度或分配的时间单位；该符号资源用于指示接收第一信号的时域资源。
步骤5012、根据子帧资源、频域资源、符号资源和定时，对第一信号进行测量。
可选地，第一UE确定接收第一信号的时域资源单元，包括：第一UE根据静态指示方式、半静态指示方式或动态指示方式确定接收第一信号的时域资源单元。
可选地，第一UE确定接收第一信号的符号资源和定时，包括：根据预设的定时偏置、控制信道资源信息和第一信号的参数，确定接收第一信号的符号资源和定时；控制信道资源信息用于指示下行控制区域的符号的个数；第一信号的参数用于指示符号所占用的时间长度。
下面以第一信号为第一UE在干扰感知阶段接收的至少一个第二UE发送的感知信号进行叠加之后的信号为例，详细说明第一UE在干扰感知阶段测量感知信号的过 程。
第一UE在测量第一信号时，需要确定接收第一信号的时域资源单元、频域资源、符号资源和定时等信息。在具体的实现过程中，第一UE可以根据静态指示方式确定接收第一信号的时域资源单元，比如所有调度为下行的时域资源单元或除固定时域资源单元外所有调度为下行的时域资源单元，也可以根据半静态指示方式确定接收第一信号的时域资源单元，例如通过RRC信令确定，还可以根据动态指示方式确定接收第一信号的时域资源单元，对于时域资源单元的具体的确定方式，本实施例在此不作限制。
需要进行说明的是，时域资源单元例如可以为子帧，其中，子帧的结构与第二UE在发送感知信号时确定的子帧的结构类似，此处不再赘述。
另外，第一UE可以根据预设的定时偏置、控制信道资源信息和第一信号的参数，确定测量第一信号的符号资源和定时。其中，第一信号的参数例如可以为时域资源可以占一个符号的时间间隔，如子载波间隔是15kHz时，一个符号的持续时间是66.7us。其中，第一UE确定测量第一信号的符号资源和定时的方式与第二UE确定发送第二信号的符号资源和定时的方式类似，此处不再赘述。
另外，第一信号的频域资源可以由第一UE被调度分配的PRB编号指示，也可以位于预定义的频域资源上。
第一UE在第一时频资源上对第一信号进行测量获得的测量结果可以是第一信号的无线资源管理(Radio Resource Management；简称：RRM)测量结果，例如第一信号的参考信号接收功率(Reference Signal Received Power；简称：RSRP)。
举例来说，图8为第一UE根据预定义指示方式确定时域资源单元的示意图，如图8所示，第二UE在预定义的传输资源上发送感知信号，第一UE在预定义的传输资源上检测和感知干扰类型，包括有无干扰和干扰强度等。其中，预定义的传输资源可以占据系统带宽的中间N个资源块(Resource Block；简称：RB)的固定传输资源，也可以占据系统带宽的其他固定传输资源，对于传输资源的具体位置，本实施例在此不作限制。本实施例中以N为2为例进行说明，如图8所示，假设第一UE所在小区周围存在三个第二UE，即三个第二UE均要发送感知信号，第二UE1、第二UE2和第二UE3的感知信号所占的资源相同，将感知信号所占的RB上具体发送的符号设置为全1，且功率保持一致。由于三个第二UE发送的感知信号所占的资源完全相同，因此，感知信号会叠加在一起。第一UE通过对叠加后的感知信号进行测量，即可获得干扰强度。
图9为第一UE根据动态指示方式确定时域资源单元的示意图，如图9所示，第二UE根据下行控制信息(Downlink Control Information；简称：DCI)类型和下行调度分配可以确定物理下行共享信道(Physical Downlink Shared Channel；简称：PDSCH)的资源分配类型，并根据该资源分配类型确定分配给第二UE的传输资源，确定出传输资源之后，将根据虚拟资源块(Virtual Resource Block；简称：VRB)到PRB的资源映射类型，得到所分配资源的PRB编号，然后在PRB编号对应的PRB上发送感知信号。同样地，第一UE根据DCI类型和上行调度分配可以确定物理上行共享信道(Physical Uplink Shared Channel；简称：PUSCH)的资源分配类型，并根据该资源分 配类型确定分配给第一UE的传输资源，，确定出传输资源之后，将根据VRB到PRB的资源映射类型，得到所分配资源的PRB编号，然后在PRB编号对应的PRB上对第一信号进行测量和感知，其中，资源分配类型为传输资源的分配方式，例如包括集中式分配或分布式分配等。
如图9所示，假设第一UE所在小区周围存在三个第二UE，即三个第二UE均要发送感知信号，第二UE1、第二UE2和第二UE3均需要完成感知信号的资源映射，将感知信号所占的RB上具体发送的符号设置为全1，且功率保持一致。由于三个第二UE发送的感知信号所占的资源并非完全正交，因此，会有叠加现象出现。第一UE按照DCI和相关字段指示的资源分配和映射后的RB位置进行测量和感知，以获得测量结果。其中，相关字段例如可以为UL Grant中指示的上行资源。
步骤502：第一UE根据测量结果控制所述第一时域资源单元上的上行功率。
其中，上行功率可以包括上行数据的功率和/或上行控制信息的功率。
在本实施例中，第一UE在获得测量结果之后，将根据该测量结果控制上行功率，以降低对各第二UE的干扰，从而达到提升系统吞吐量的目的。
可选地，第一时频资源属于第一时频资源单元，则第一UE根据测量结果控制上行功率，包括：第一UE根据测量结果，在该第一时频资源单元上控制上行功率。
具体地，第一时频资源单元为当前的时频资源，因此，第一UE在确定出测量结果之后，将在当前的时频资源上控制上行功率，也即在本子帧上控制上行功率。
可选地，第一UE根据测量结果控制上行功率，包括：第一UE根据测量结果在预设的功率控制参数集合中选择至少一个上行功率控制参数集，并根据该功率控制参数控制上行功率。
其中，预设的功率控制参数集合至少包括由网络侧设备半静态配置的开环参数集
Figure PCTCN2017103610-appb-000002
和由DCI指定的闭环TPC参数。
具体地，第一UE在第一时频资源上对第一信号进行测量，获得测量结果之后，将根据测量结果在网络侧设备配置的功率控制参数集合中进行选择，以选择至少一个合适的功率控制参数。
可选地，根据测量结果在预设的功率控制参数集合中选择至少一个上行功率控制参数集，包括：根据测量结果确定第一UE感知到的干扰强度；对干扰强度进行量化处理，获得干扰等级；根据干扰等级，在预设的功率控制参数集合中选择至少一个上行功率控制参数集。
具体地，第一UE可以根据不同的RB上的测量结果所在的预设的干扰测量区间，确定每个RB在干扰强度计算中的权重值，再根据该权重值获得第一UE感知到的干扰强度。在具体的实现过程中，第一UE在确定出每个RB在干扰强度计算中的权重值之后，将根据该权重值获得第一UE感知到的干扰强度。其中，干扰强度与每个RB上的测量结果有关，其可以通过公式进行计算，对于干扰强度的具体形式，本实施例在此不作限制。
举例来说，若预设的干扰测量区间根据不同的功率强度可划分为N个区间，其中，N为正整数，在本实施例中，以N＝5为例，则5个干扰测量区间及对应的权重值如表1所示：
表1
干扰测量区间 权重值
(-20dBm,-10dBm) 0.1
(-10dBm,0dBm) 0.3
(0dBm,5dBm) 0.6
(5dBm,10dBm) 1.0
(10dBm,15dBm) 2.0
如在三个RB上测量的干扰功率分别为：-15dBm，-3dBm,6dBm，则感知到的干扰强度为0.1+0.3+1.0＝1.4。
第一UE在确定出干扰强度之后，根据预设的干扰阈值，对确定出的干扰强度进行量化处理，确定出干扰等级。在实际应用中，可以根据预设的干扰强度和干扰等级之间的映射关系，获得干扰等级。例如：在确定出干扰强度之后，根据表2中的映射关系，获得干扰等级。
表2
干扰强度 干扰等级
0～1.0 1
1.0～2.0 2
2.0～2.5 3
2.5～3 4
3.5～4.0 5
根据表2中的映射关系，在干扰强度为1.4时，干扰等级为2。
由于网络侧设备将提供N种可选择的功率控制参数集合供第一UE根据测试结果灵活选择，每种可选功率控制参数集合对应第一UE的不同的发射功率，使得第一UE的选择更加灵活，其中，N为大于或等于2的整数。第一UE根据确定出的干扰等级，在功率控制参数集合中选择合适的功率控制参数，以控制上行功率。举例来说，图10为干扰等级和功率控制参数之间的映射图，如图10所示，干扰等级可以分为N级，本实施例中以N＝9为例进行说明。假设第一UE确定出的干扰等级为4，则根据图7中的映射关系，即可选择出功率控制参数为P0_4，
Figure PCTCN2017103610-appb-000003
和TPC_4。
本领域技术人员可以理解，一种可选的预定义可以为：干扰等级越高，说明第一UE如果不进行上行功率的控制，则会对邻小区的第二UE产生越大的干扰。因此，第一UE根据确定出的干扰等级选择合适的上行功率控制参数，进行后续上行子帧的发送。
本申请实施例提供的上行功率控制方法，第一UE在第一时频资源上对第一信号进行测量，获得测量结果，并根据该测量结果控制上行功率。由于第一UE通过对第一信号进行动态的测量和感知，根据测量结果灵活的控制上行功率，因此，可以有效地降低UE之间的交叉干扰，从而大大提高了系统的吞吐量。
另外，需要强调的是，由于不同的终端设备厂商生产的UE采用的干扰测量的机制和精度等有所差异，可能会导致干扰测量的不一致性和功率参数选择时的不公平性，为了解决这一问题，可采用如下方案：在UE接入网络的初始阶段，可以向网络侧设 备上报其测量能力，由网络侧设备根据各UE具有的不同的干扰测量能力下发给其可选的参数集合。
