Embodiment Construction

[0028] The embodiment of the present invention can be used in all communication modes that support CA scenarios, for example, LTE-A, Wideband Code Division Multiple Access (WCDMA for short), Time Division Synchronous Code Division Multiple Access (Time Division -Synchronous Code Division Multiple Access, referred to as TDSCDMA), WIFI or future communication standards.

[0029] figure 1 It is a flowchart of a method for dealing with harmonic interference provided by an embodiment of the present invention. Such as figure 1 As shown, the method provided in this embodiment includes:

[0030] Step 11: Before performing resource scheduling on the user equipment, the base station determines whether the harmonics of the uplink frequency resources to be used by the user equipment in the current CA scenario will cause harmonic interference to the downlink frequency resources to be used by the user equipment.

[0031] Before performing resource scheduling on the user equipment, the ba...

Abstract

Provided are a method for processing harmonic interference, and a base station. The method comprises: before resource scheduling is conducted on a user equipment, determining, by a base station, whether a harmonic of an uplink frequency resource which is to be used by the user equipment in a current carrier aggregation scenario will generate harmonic interference to a downlink frequency resource which is to be used by the user equipment; if it is determined that the harmonic interference will be generated, acquiring a transmitting power of the user equipment and a relative energy value of a harmonic component of the uplink frequency resource which is to be used by the user equipment and a principal component, and also being capable of acquiring the channel state quality of the user equipment, and according to the acquired information, determining a change value of the reference signal receiving quality of the user equipment subjected to the harmonic interference; and if the change value of the reference signal receiving quality of the user equipment subjected to the harmonic interference exceeds a preset threshold value, adjusting a scheduling solution of the user equipment. The embodiments of the present invention reduce the interference of harmonic interference when the user equipment receives signals.

Description

technical field [0001] The present invention relates to communication technology, in particular to a method and base station for dealing with harmonic interference. Background technique [0002] Carrier Aggregation (Carrier Aggregation, CA for short) technology is an important feature of Long Term Evolution Advanced (LTE-A for short). CA is divided into three types: intra-band continuous, intra-band non-continuous and inter-band. In the inter-band CA scenario, due to the difference in the band frequency band and the interference problem, it is divided into different inter-band CA types (inter-band CA class A1, inter-band CA class A2, inter-band CA class A3 and inter- band CA class A4). Among them, inter-band CA class A2 is low-high band carrier aggregation and has harmonic interference problems. For example, when band4 and band17 carrier aggregation, the 3rd harmonic of band17 will overlap with the downlink reception of band4, resulting in a decrease in the sensitivity of ...
