下行共享信道通信方法及设备技术

本发明专利技术涉及无线通信领域，公开了一种下行共享信道通信方法及设备。本发明专利技术中，通过先检测无效单元，根据无效单元的检测情况对盲检测译码的搜索空间进行优化，再进行盲检测译码，可以有效地减少下行物理信道的盲检测译码的试探次数，节约了终端的处理能力和电池能量。无效单元被定义为数据信号部分不发射、相关参考信号部分照常发射，终端侧可以通过比较数据信号部分平均能量与参考信号部分平均能量的相对关系而判断出收到的是否无效单元。因为数据信号部分不发射，所以减少了发射端的电能需求，并且减轻了对相邻基站的干扰。

Downlink shared channel communication method and apparatus

The invention relates to the field of wireless communication, and discloses a downlink shared channel communication method and equipment. In the invention, by first detecting invalid unit, according to the detection unit of blind detection and decoding invalid search space is optimized, then the blind detection algorithm, can effectively reduce the test number of blind detection and decoding downlink physical channel, saving the terminal processing capacity and battery energy. The invalid unit is defined as the data signal part is not sent, the reference signal part is sent as usual, the terminal side can through the relative relationship between the data signal part of the average energy and average energy and the reference signal part determine whether the received invalid unit. Because the data signal part is not transmitted, the power demand of the transmitter is reduced, and the interference to the adjacent base station is reduced.
