Problems solved by technology

[0011] In the existing technology, the transmit diversity technology and the layered cell technology are independent of each other, that is, either the transmit diversity technology or the layered cell technology is used. The setting of the layered cell mainly depends on the carrier, coverage distance, output power, antenna position, etc. The difference between stratified cells, but not making full use of transmit diversity to obtain more performance gains for various hierarchical cells

Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0034] The core of the present invention is that, according to the characteristic that the gain of the open-loop transmit diversity mode is relatively obvious under high-speed motion conditions, and the closed-loop transmit diversity mode can provide a relatively high gain under low-speed motion conditions, it is a layered cell with a larger coverage area. Assign open-loop transmit diversity mode (UEs tend to move faster in cells with larger coverage areas), and assign closed-loop transmit diversity modes to stratified cells with smaller coverage areas (UEs move faster in cells with smaller coverage areas). slower). It enables different types of hierarchical cells to use their appropriate transmit diversity techniques, and obtain more performance gains through cor...

Abstract

The invention relates to a method for setting laminated region and emission group mode, to make the laminated regions in different levels obtain more property increment via emission group, wherein the different laminated levels are relative to the regions with different cover areas; the region belonging to the first level group uses the open emission group mode; the region belonging to the second level group uses the close emission group mode; the average cover area of first level group is larger than the second one; each laminated level is only belong to one level group; when hardware switching between special-frequency laminated regions, the emission group mode character of UE will be set via the group mode of target region.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to layered cell technology. Background technique [0002] The application of mobile communication in today's society is becoming more and more extensive, and the cell frequency coverage technology in mobile communication is also constantly improving. In the initial stage of mobile communication system application, because the traffic volume is not large, often a cell covers a relatively large area. With the increasing number of users, it is difficult for the system to meet the increasing traffic demand. At this time, a cell with a different frequency is often added in some areas to absorb the traffic. In this way, a situation occurs in which multiple different-frequency cells cover the same area. [0003] As the traffic volume continues to increase, the system will be further expanded in hot spots with very high traffic volume in actual situations, and one of the frequency cell...
