Abstract

The invention discloses an information scheduling method, an information receiving method and related apparatuses. Different cross-carrier scheduling indications can be configured flexibly for controlinformation on carriers, so that a compromise for transmission of the control information between reliability and a transmission delay can be implemented. The method comprises the following steps: abase station configures cross-carrier scheduling indications for a first carrier, wherein the cross-carrier scheduling indications include a cross-carrier scheduling indication for a first type of control information and / or a cross-carrier scheduling indication for a second type of control information; the base station determines a corresponding target carrier according to the cross-carrier scheduling indications; and the base station transmits the control information on the first carrier on the target carrier.

Description

technical field [0001] The present application relates to the communication field, and in particular to an information scheduling method, a receiving method and a related device. Background technique [0002] Currently, Long Term Evolution (LTE for short) and Long Term Evolution-Advanced (LTE-A for short) systems introduce carrier aggregation technology between base stations. Aggregation technology is also known as dual connectivity technology. In the dual connectivity technology, the transmission of data between two base stations performing carrier aggregation can be ideal backhaul or non-ideal backhaul, so the downlink subframe sent by the two base stations to the user equipment (English: User Equipment, referred to as: UE) The starting moment of can be synchronous (for example, a dual connectivity scenario of carrier aggregation) or asynchronous (for an asynchronous dual connectivity scenario). In an asynchronous scenario, there may be any time difference between the st...
