Description

通信方法和装置 技术领域
本发明涉及通信领域，尤其涉及一种通信方法和装置。
背景技术
在现有的LTE(Long Term Evolution，长期演进)系统中，下行通常采用OFDMA(Orthogonal Frequency Division Multiple Access，正交频分多址)技术。为了有效提升小区中心和小区边缘的吞吐量，NOMA(Non-Orthogonal Multiple Access，非正交多址)技术是一种潜在的候选技术。采用NOMA进行通信时，基站给不同的用户设备(user equipment,UE)分配不同的功率，但不同的UE可以使用相同的频率资源。
使用相同的时频资源块跟基站通信的两个或多个UE，被称为配对UE。比如在采用NOMA技术时，UE1和UE2使用相同的时频资源块跟基站进行通信，UE2和UE1为配对UE。基站采用不同的发射功率，向UE1和UE2发送信号。UE1的下行信号和UE2的下行信号间会有干扰。下行，通常是指基站到UE的方向。为了有效地提取UE1的下行信号，UE1需要消除掉UE2的下行信号的干扰。现有技术中，UE1无法获取UE2下行信号的相关信息，不能实现采用NOMA技术进行通信。

一种可选的实施方式，所述处理单元302具体用于根据所述第三发射功率和所述第一发射功率确定所述第二发射功率。其中所述第三发射功率的确定是根据所述第一UE的功率参数确定的，确定的具体实施方式可以参见上述描述。
一种可选的实施方式，所述第二发射功率为所述所述第三发射功率和所述第一发射功率的差值。
一种可选的实施方式，第一UE获取第一UE的下行数据时，第一UE需要使用先进接收机，如极大似然(maximum likehood,ML)接收机或码字级干扰删除(codeword interference cancellation,CWIC)接收机等。
第一UE使用最大似然接收机时，可以将第一UE和第二UE的可能候选下行信号与接收信号相匹配，确定出第一UE的下行信号对应比特的软信息，从一般意义上来讲，第二UE的下行信号对第一UE来说是干扰信号，有效的设计第一UE和第二UE的发送星座图，可以等效的增大第一UE下行信号对应比特距离，从而提高传输的可靠性，如第一UE和第二UE的合成星座图符合格雷映射等。所述第一UE的下行信号携带第一UE的下行数据。
第一UE使用CWIC接收机时，首先将第二UE的下行信号解调出来，然后从接收信号中将第二UE的下行信号减掉，得到第一UE的下行信号。
第二UE可以将第一UE的下行信号当成干扰，直接使用现有的常规接收机。
比如，假设第一UE对应的信道系数为H1，受到噪声干扰为σ1。第二UE对应的信道系数为H2，受到噪声干扰为σ2。基站发送的第一UE的下行信号X1的第一发射功率为P1，基站在相同的时频资源上发送第二UE的下行信号X2的第二发射功率为P2。则此时第一UE和第二UE接收信号分别为Y1和Y2，分别表示为：
Figure PCTCN2014095994-appb-000048
Figure PCTCN2014095994-appb-000049
对于第一UE而言，接收到的接收信号Y1，通过信道估计和噪声估计分别得到信道H1和干扰σ1，根据功率P1和P2；然后优先解出第二UE的下行信号X2，根据上述公式，第一UE 可以解出第一UE的下行信号X1。
需要注意的是，在以上求解第一UE的下行信号X1过程中，第一UE之所以可以优先求解X2然后减掉X2以获得对X1的更精确的估计，原因是在于第一UE的信噪比高于第二UE，所以第一UE可以正确的解出第二UE的下行信号X2。所以对于第二UE而言，由于无法正确求解第二UE的下行信号X1，所以只能按照以下公式直接求解X2：
Figure PCTCN2014095994-appb-000050
发明实施例二中，第一UE的接收单元301接收基站发送的发送的第一UE的功率参数和第一发射功率的调整参数δ1,ue1，第一UE的处理单元302根据第一用户设备UE的功率参数获取第一发射功率，并根据第一UE的功率参数和第一发射功率确定第二发射功率。第一UE能够根据第二发射功率消除掉第二UE的信号的干扰，实现采用NOMA技术进行通信。

为所述第二高层提供的所述第二UE的的UE特定的参数，第二高层为第二UE的高层，比如可以为第二UE的基站。在此场景下，由于第一UE功率参数
Figure PCTCN2014095994-appb-000054
和第二UE的功率参数
Figure PCTCN2014095994-appb-000055
相同，可以认为分别根据第一UE功率参数和第二UE的功率参数确定得到发射功率相同。因此根据第一UE可以根据第一UE功率参数获得第二发射功率。基站把第一UE功率参数发送给第一UE，第一UE能够根据第二发射功率消除掉第二UE的信号的干扰，实现采用NOMA技术进行通信。
