Abstract

An embodiment of the invention provides a signaling transport method. The signaling transport method includes receiving an up data frame transmitted by user equipment (UE), and according to whether the up data frame is received correctly, determining feeding back acknowledgement or negative acknowledgement (ACK / NACK) information to the UE; sending down control information (DCI) to the UE on a physical down control channel (PDCCH) or an enhanced physical down control channel (ePDCCH), wherein the DCI comprises a response information field of L bits, the response information field of L bits carries the ACK / NACK information, and L is an integer greater than 1. The signaling transport method relieves the problem of the physical information channel (PHICH) capacity tension due to the fact that a PHICH feeds back response information to the UE in a traditional mode, thereby improving the operation efficiency.

Description

technical field [0001] The embodiments of the present invention relate to the field of wireless communication, and more specifically, to a signaling transmission method and device. Background technique [0002] In a Long Term Evolution (LTE for short) system or a Long Term Evolution Advanced (LTE-A for short) system, a base station Evolved NodeB (eNB for short) receives a message sent by a user equipment (User Equipment, UE for short). After the uplink data packet, an Acknowledgment (ACK for short) / Non-Acknowledgment (NACK for short) message needs to be sent to the user equipment through a Physical hybrid-ARQ indicator channel (PHICH for short). If the base station correctly receives the uplink data packet sent by the UE, it will feed back an ACK to the UE through the PHICH; otherwise, if the base station does not correctly receive the uplink data packet sent by the UE, it will feed back a NACK to the UE through the PHICH. After receiving the NACK message, the UE retransmit...
