Title: CARRIER AGGREGATION-BASED INFORMATION TRANSMITTING METHOD AND DEVICE
Abstract:
Provided by the present application are a carrier aggregation-based information transmitting method and device, the method comprising: a terminal detects downlink control information transmitted by a base station in a first downlink subframe of a carrier aggregation group and/or downlink indication information transmitted by the base station in a second downlink subframe, the carrier aggregation group comprising: a first carrier and a second carrier. The terminal determines a first time sequence according to a subframe configuration of the first carrier and a subframe configuration of the second carrier; the terminal determines a first uplink subframe and a preset bound uplink subframe of the first uplink subframe in a subframe of the first carrier or the second carrier according to the first time sequence; and the terminal transmits uplink data to the base station in the first uplink subframe and the preset bound uplink subframe of the first uplink subframe. With the present invention, the opportunities for uplink transmission are increased, and uplink coverage is enhanced.
