Embodiment Construction

[0048] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. It will be understood that, with the attached Figure 1 The detailed description disclosed above is intended to describe exemplary embodiments of the invention, and is not intended to describe the only embodiments in which the invention can be practiced. The following detailed description includes details to provide a complete understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without this detail. For example, although the following description will be made based on a mobile communication system corresponding to the 3GPP LTE system, the following description may be applied to other mobile communication systems in addition to unique features of the 3GPP LTE system.

[0049] In some cases, structures and devices of known art will be omitted or will be shown in b...

Abstract

A method for performing communication using a frame structure that supports a half-frequency division duplex (H-FDD) operation and a device using the same are disclosed. A base station performs resource allocation scheduling to support H-FDD user equipment operation in a mobile communication system. For example, the base station allocates first, second and last uplink subframes for idle subframes within a specific frame or punctures them, so that the H-FDD user equipment does not use the uplink subframes. The base station transmits the scheduled resource allocation information to the user equipment through a superframe header, a preamble and a MAP. The user equipment which has received the scheduled resource allocation information (subframe index and location that can be used by the user equipment) transmits and receives a signal based on the resource allocation information.

Description

technical field [0001] The present invention relates to a mobile communication system, and more particularly, to a method of performing communication using a frame structure supporting H-FDD operation and an apparatus using the method. Background technique [0002] The IEEE 802.16m system may support a frequency division duplex (FDD) scheme and a time division duplex (TDD) scheme, the frequency division duplex scheme including half frequency division duplex (H-FDD) user equipment operation. The IEEE 802.16m system uses Orthogonal Frequency Division Multiple Access (OFDMA) as a multiple access mode in downlink and uplink. [0003] Hereinafter, the frame structure of the IEEE 802.16m system will be briefly described. [0004] figure 1 is a diagram showing the structure of a basic frame in the IEEE 802.16m system. [0005] refer to figure 1 , each 20ms superframe includes four 5ms radio frames of the same size, and starts with a superframe header (SFH). If any one of chann...
