WIPO Patent Application WO/2017/173594

Kind Code:

A1

Abstract:

Disclosed in an embodiment of the present invention are an information processing method and a device for use in a multi-carrier communications system. In a multi-carrier communications system, a terminal is configured with a PCC and at least one SCC. The present method comprises: a first base station transmits downlink data to the terminal via a PDSCH on the PCC, said first base station being a base station the PCC is on; the first base station utilizes a first format and a second format to demodulate a PUCCH on the PCC so as to obtain feedback information sent by the terminal, the first format being a PUCCH format used for a single serving cell, and the second format being a PUCCH format used for multiple serving cells. The embodiments of the present invention uses two formats to demodulate the PUCCH to acquire feedback information, solving the problem of inconsistent PUCCH formats making it impossible to demodulate feedback information, which leads to constant downlink retransmission.
