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 should also be understood...

Abstract

The present disclosure provides a method and device for indicating a transmission direction, wherein the method includes: determining a detection method for detecting the transmission direction of each configured bandwidth part; detecting the transmission on the corresponding bandwidth part according to the detection method Direction indication information; determine the transmission direction of the corresponding bandwidth part according to the detected transmission direction indication information. In the present disclosure, the terminal can accurately know the transmission direction of each bandwidth part, which reduces the detection overhead of the terminal.

Description

technical field [0001] The present disclosure relates to the communication field, and in particular to a method and device for indicating a transmission direction. Background technique [0002] In the LTE (Long Term Evolution, long-term evolution) system, according to the duplex mode, it can be divided into two operation modes: FDD (Frequency Division Duplexing, frequency division duplexing) and TDD (Time Division Duplexing, time division duplexing) . For the 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 pre-defined, and it is impossible to change the uplink and downlink transmission directions of the terminal dynamically. [0003] In a new generation communication system, the uplink and downlink transmission directions of a terminal may chang...
