Embodiment Construction

[0189] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0190] The terminology used in the present disclosure is for the purpose of describing particular embodiments only, and is not intended to limit the present disclosure. As used in this disclosure and the appended claims, the singular forms "a", "the", and "the" are intended to include the plural forms as well, unless the context clearly dictates otherwise. It will also be understood t...

Abstract

The present invention provides a method and device for indicating a transmission direction. The method comprises: determining a detection mode used for detecting a transmission direction of each configured bandwidth section; detecting transmission direction indicating information on a corresponding bandwidth section according to the detection mode; and determining the transmission direction of thecorresponding bandwidth section according to the detected transmission direction indicating information. In the present invention, a terminal can accurately know the transmission direction of each bandwidth section, thereby reducing costs in detection of the terminal.

Description

technical field [0001] The present disclosure relates to the field of communications, and in particular, to a method and device for indicating a transmission direction. Background technique [0002] In an LTE (Long Term Evolution, Long Term Evolution) system, according to different duplex modes, it can be divided into two operation modes: FDD (Frequency Division Duplexing, Frequency Division Duplexing) and TDD (Time Division Duplexing, Time Division Duplexing) . For FDD mode, uplink and downlink transmissions are implemented on different carriers. For TDD mode, uplink and downlink transmissions are implemented on the same carrier. Moreover, in the design of the LTE system, the uplink and downlink transmission directions of the terminal are predefined, and it is impossible to completely dynamically change the uplink and downlink transmission directions of the terminal. [0003] In a new generation communication system, the uplink and downlink transmission directions of the...
