Uplink power detection method, device and base station equipment

Abstract

Embodiments of the present invention provide a method, an apparatus, and a base station device for detecting uplink power. The method includes: detecting a modulation and coding scheme and an initial block error rate of an uplink data packet sent by a user equipment; determining, according to a relationship between an index of the detected modulation and coding scheme of the uplink data packet sent by the user equipment and a first threshold, and a relationship between the detected initial block error rate of the uplink data packet sent by the user equipment and a second threshold, whether uplink power of the user equipment is restricted. In the embodiments of the present invention, a base station device detects a modulation and coding scheme and an initial block error rate of an uplink data packet sent by a UE, and can determine, according to the detected modulation and coding scheme and initial block error rate, whether uplink power of the UE is restricted, thereby accurately characterizing an uplink signal restriction situation of the UE.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method, device and base station equipment for uplink power detection. Background technique [0002] When the network coverage is limited, the base station will trigger cell handover. Existing cell handover is triggered by downlink signal quality, that is, when the downlink signal quality is lower than a certain threshold, a terminal (User Equipment, hereinafter referred to as UE) is triggered to perform cell handover. However, in network planning, there is a phenomenon of unbalanced uplink and downlink power, so that uplink coverage may be limited before downlink coverage, that is, uplink coverage is already limited when downlink coverage is not limited. Especially in the scenario where there is uplink interference, the UE's uplink transmit power is more likely to be limited before the downlink, thus causing the uplink coverage to be limited...

Problems solved by technology

However, in network planning, there is a phenomenon of unbalanced uplink and downlink power, so the uplink coverage may be limited before the downlink coverage, that is, the uplink coverage is already limited when the downlink coverage is not limited.

Especially in the scenario where there is uplink interference, the UE's uplink transmit power is more likely to be limited before the downlink, resulting in the uplink coverage being limited before the downlink coverage

If the UE's uplink transmit power is limited, call drop is more likely to occur

[0003] The problem existing in the cell handover method in the prior art is: the handover is triggered by the quality of the downlink signal, which cannot accurately characterize the situation where the uplink signal is limited. When the uplink coverage is limited before the downlink coverage, because the downlink signal quality has not The threshold value for triggering handover is reached, so the handover will not be triggered, which makes the UE prone to call drop
