Problems solved by technology

However, because the femtocell network and the outdoor macro network use unified terminals, the transmit power of the terminals within the coverage of the femtocell is too rich, resulting in unbalanced uplink and downlink coverage of the femtocell network. The uplink coverage is greater than the downlink coverage. It will cause uplink interference to the outdoor macro network or adjacent Femtocell wireless access equipment
For above-mentioned technical problem, prior art does not have relevant solution

Abstract

The invention discloses a method for limiting the transmitted power of a terminal, and wireless access equipment. The method for limiting the transmitted power of the terminal comprises the following steps of: acquiring a transmitted power value of the wireless access equipment; acquiring a downlink interference value in a coverage area of the wireless access equipment; determining a limited transmitted power value of the terminal according to the transmitted power value of the wireless access equipment and the downlink interference value; and controlling the transmitted power of the terminalto be not more than the limited transmitted power value of the terminal. The method limits the transmitted power of the terminal according to the transmitted power value of the wireless access equipment and the downlink interference intensity in the coverage area of the wireless access equipment to basically balance uplink coverage and downlink coverage and reduce the uplink interference of the terminal to other adjacent access equipment.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for limiting terminal transmission power and wireless access equipment. Background technique [0002] Wireless network wireless access devices are gradually developing in the direction of miniaturization and flattening. For example, Femtocell wireless access devices suitable for home or business users are a typical form of future wireless access devices. Femtocell wireless access equipment uses low-power transmission to meet the small area coverage of home or office scenarios, and its downlink coverage is much smaller than that of macro wireless access equipment. However, because the femtocell network and the outdoor macro network use unified terminals, the transmit power of the terminals within the coverage of the femtocell is too rich, resulting in unbalanced uplink and downlink coverage of the femtocell network. The uplink coverage is greater than the d...
