Abstract

The embodiment of the invention provides a direct current component carrier position reporting method, a direct current component carrier position receiving method, a terminal and equipment. The method comprises the step of reporting the position of a direct current component DC carrier under the condition that a bandwidth part BWP of carrier aggregation is combined. According to the scheme, the uplink performance of carrier aggregation can be improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a location reporting and receiving method, terminal and equipment of a DC component carrier. Background technique [0002] The OFDM (Orthogonal Frequency Division Multiplexing) system uses a zero-IF receiver. In order to avoid the interference caused by the leakage of the local oscillator, the uplink transmission in 4G technology is offset by 7.5KHz to avoid the uplink transmission caused by the DC (Direct Current, DC) carrier. Interference, 5G technology uplink uses OFDM signals, the baseband signal does not have a 7.5KHz offset, and due to the flexible transmission bandwidth (such as bandwidth part BWP, etc.), no additional processing is performed on the uplink carrier offset, but the introduction of the terminal reporting method helps The network confirms the location of the DC carrier. The terminal reports the location of the DC carrier on each BWP of each cel...
