    • A medium access control (MAC) entity first computes an achievable rate region based on a total transmit power limit and a channel gain of each of a plurality of WTRUs. Next, the MAC entity selects an order of DPC among the WTRUs. A rate set for use in transmitting to the WTRUs is then selected, said rate set being within the computed achievable rate region. Then, based on the selected DPC order and rate set, a DPC entity performs DPC on a plurality of data streams intended for the plurality of WTRUs. If nested lattice-based DPC is utilized, rate compatibility is achieved by selecting proper nesting ratios corresponding to a desired data rate set. Otherwise, if binary-code based DPC is utilized, rate compatibility is achieved via selecting appropriate message input sizes for input to point-to-point coding units prior to performing DPC.
    • 媒体接入控制(MAC)实体首先基于多个WTRU中的每一个的总发射功率限制和信道增益来计算可实现速率区域。 接下来,MAC实体在WTRU中选择DPC的顺序。 然后选择用于向WTRU发送的速率集,所述速率集合在所计算的可实现速率区域内。 然后,基于所选择的DPC顺序和速率集合,DPC实体在为多个WTRU设置的多个数据流上执行DPC。 如果利用嵌套的基于网格的DPC,则通过选择对应于期望的数据速率集合的适当的嵌套比率来实现速率兼容性。 否则,如果使用基于二进制码的DPC,则在执行DPC之前通过选择适当的消息输入大小来输入到点对点编码单元来实现速率兼容性。
