Problems solved by technology

Obviously, considering the number of UEs that may cause interference and the dynamic changes in scheduling information, the number of blind decodings that need to be performed by the victim UE will be astonishing. This seemingly simple step will become very difficult to implement, and the corresponding , it will add a lot of complexity to the design of the UE, so that it cannot be practically applied and must be improved

Embodiment Construction

[0030] In the following detailed description of the preferred embodiment, reference is made to the accompanying drawings which form a part hereof. The accompanying drawings show, by way of example, specific embodiments in which the invention can be practiced. The illustrated embodiments are not intended to be exhaustive of all embodiments in accordance with the invention. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present invention. Accordingly, the following detailed description is not limiting, and the scope of the invention is defined by the appended claims.

[0031] Firstly, according to the application scenario of the present invention, there is a victim UE. Since the victim UE uses the same PRB as some UEs (called interfering UEs) in adjacent cells, it will be interfered by the Co-channel of these interfering UEs. Therefore, the victim UE needs to perform a blind de...

Abstract

A method for reducing interference on an interfered user equipment in a wireless communication system, wherein the interfered user equipment suffers interference from at least one interfering user equipment from other cell, the method comprising: receiving, by the interfered user equipment, a first message sent from a serving base station of the interfering user equipment, wherein the first message includes content associated with blind decoding scheduling information of the interfering user equipment; blind decoding, by the interfered user equipment, on a physical downlink control channel of the serving base station of the interfering user equipment, the scheduling information of the interfering user equipment based on the first message.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to the technical field of wireless communication. Background technique [0002] In the field of wireless communication, the problem of inter-cell interference has always been a hot research direction in recent years. Especially with the increasingly widespread application of heterogeneous network structures, how to solve the inter-cell interference caused by high-power macro cells to low-power micro cells has become an urgent practical problem to be solved. The industry has also proposed many targeted solutions. For example, in the 3GPP specification, methods such as Inter-Cell Interference Coordination (ICIC for short) technology are adopted to reduce the impact of inter-cell interference on wireless communication. [0003] However, with the further growth of wireless services, especially wireless data services, the capacity requirements for wireless communication s...
