Title:

SIGNAL TRANSMISSION APPARATUS, WIRELESS ACCESS NODE AND METHOD

Document Type and Number:

WIPO Patent Application WO/2016/082084

Kind Code:

A1

Abstract:

The present invention relates to the technical field of communications. Disclosed are a signal transmission apparatus, a wireless access node and a method, which can solve the problem of insufficient spectrum utilization. The method of the present invention comprises: a wireless access node acquires configuration information, wherein the configuration information is used by the wireless access node to transmit a signal of a second carrier in the space covered by a first carrier, the spectrum occupied by the first carrier overlaps with the spectrum occupied by the second carrier, and a subcarrier of the first carrier is orthogonal to a subcarrier of the second carrier; and the wireless access node transmits the signal of the second carrier according to the configuration information. The present invention is applicable to the scenario in which a signal of one carrier is transmitted in the space covered by another carrier.
