对HSPA+与LTE中对MIMO技术的使用进行了详细比较和分析。这种比较涉及3个层面,分别是HSPA+及LTE支持的MIMO技术、HSPA+及LTE对MIMO控制信号支持和HSPA+与LTE终端对MIMO的支持及复杂度分析。通过上述比较可以看出,相对于LTE,HSPA+中MIMO技术支持更加简化,控制信道开销小,但HSPA+对于单用户MIMO的支持硬件复杂度会有所提升。
The use of MIMO technology in HSPA + and LTE is compared and analyzed in detail. The comparison involves three aspects: MIMO technology supported by HSPA + and LTE, HSPA + and LTE support for MIMO control signals, and support and complexity analysis for MIMO supported by HSPA + and LTE terminals. As can be seen from the above comparison, in contrast to LTE, MIMO technology support in HSPA + is more simplified and the control channel overhead is small, but the hardware complexity of HSPA + support for single-user MIMO is improved.
