Embodiment 2

[0199] The second embodiment is that the radio access network equipment (such as the base station) makes the decision to adjust the RSRP threshold (the first RSRP threshold adjustment decision) according to the proportion of edge users and the spectral efficiency distribution of user equipment in the cell. If it is to be increased by 3dB, Then tell the decision to O&M, O&M inspects the situation of each neighboring cell, and then arrives at the final decision (the second RSRP threshold adjustment decision), if considering the adverse effects on the neighboring cell, it can only be increased by 2dB, or considered to increase 3dB can be accepted, and finally the final decision is told to the base station, that is, the second RSRP threshold adjustment decision of each cell is fed back to the corresponding cell; in this scheme, the RSRP threshold adjustment decision is initially made in the base station, and then the wireless connection The network-connected equipment only tells O&M...

Embodiment 1

[0200] The first embodiment is that the radio access network equipment (such as the base station) informs the O&M of the proportion of edge users and the spectrum efficiency distribution of all user equipment in the cell, and then the O&M compares it with the corresponding threshold to adjust the RSRP threshold. Finally, the decision is told to the base station. In this scheme, the RSRP threshold adjustment decision is completely made in O&M, and the O&M directly informs the base station to execute the decision after making a reasonable decision. In this solution, what the radio access network device informs the O&M is the proportion of users at the edge of each cell and the spectrum efficiency information of users in the cell, instead of the RSRP threshold adjustment decision in the second embodiment.

[0201] For the convenience of description, each part of the above-mentioned device is divided into various modules or units by function and described separately. Of course, when...

Abstract

The invention discloses a reference signal received power threshold adjusting method and equipment; the method comprises the following steps that: the proportion of users on the edge of a community and the spectrum efficiency of all user equipment of the community are determined; and the reference signal received power threshold is adjusted according to the proportion of the users on the edge andthe spectrum efficiency of the user equipment of the community. The invention can enable an interference coordination technology among communities to play a better role, improves the throughput, the spectrum efficiency, QoS and other properties of the users on the edge, further ensures the overall performance of a system, and reduces nonideal community throughput, spectrum efficiency property andother phenomena brought by incorrect resource use restriction caused by the inappropriate setting of the reference signal received power threshold.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a method and equipment for adjusting a reference signal received power threshold. Background technique [0002] In the LTE (Long Term Evolution, long-term evolution) system, the ICIC (Inter-Cell Interference Coordination, inter-cell interference coordination) technology is used to reduce the same-frequency interference between adjacent cells and ensure the QoS (Quality of Service, service) of edge users. Quality), the purpose of introducing ICIC technology is to reduce the same-channel interference between adjacent cells, improve the throughput and user satisfaction performance of cell edge users. [0003] The ICIC technology supported by LTE includes static interference coordination and semi-static interference coordination. The semi-static interference coordination needs to be realized by exchanging their respective load information on the X2 interface. figure 1 It is a sch...
