Problems solved by technology

[0006] In addition, although the increase in the number of antennas can increase the average signal-to-interference-noise ratio (SINR) of cell-edge terminals by reducing the probability of interference occurrence, there is a problem that sometimes the worst SINR cannot be improved

Embodiment Construction

[0031] A wireless device may be fixed or mobile and may be referred to by another term such as User Equipment (UE), Mobile Station (MS), User Terminal (UT), Subscriber Station (SS), Mobile Terminal (MT), etc. . A base station is typically a fixed station that communicates with wireless devices and may be called by another term such as an evolved Node B (eNB), base transceiver system (BTS), access point, and so on.

[0032] Hereinafter, the present invention is applied based on 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) or 3GPP LTE-Advanced (LTE-A). This is for exemplary purposes only, so the invention is applicable to various communication systems. In the following description, LTE and / or LTE-A are collectively referred to as LTE.

[0033] This specification is described based on a communication network. A task implemented in a communication network may be implemented in a process of controlling the network and transmitting data in a system for mana...

Abstract

Provided are a method and an apparatus for generating and transmitting feedback signals for a plurality of reference signals having different directionality, in a wireless communication system. A terminal may receive the plurality of reference signals having different directionality, and transmit, to a transmission end, a feedback signal including a beam index which indicates one of the plurality of reference signals.

Description

technical field [0001] The present invention relates to a method and device for sending a feedback signal, and more particularly, to a method and device for sending a feedback signal for a terminal receiving multiple beams with different directivities. Background technique [0002] Recently, commercialization of a Long Term Evolution (LTE) system, which is a next-generation wireless communication system, has been eagerly supported. After recognizing the necessity of supporting not only voice services but also high-quality mass services in response to users' needs while ensuring activity of users of terminals, LTE systems tend to increase more rapidly than before. The LTE system provides low transmission delay, high transfer rate, and improved system capacity and coverage. [0003] With the introduction of such high-quality services, the demand for wireless communication services is growing rapidly. Above all, the capacity of the communication system must be increased to ac...
