Abstract
A method of resource allocation for Channel State Information (CSI) feedback is provided, which comprises the following steps of: configuring a downlink transmission approach and a feedback mode for each User Equipment (UE); allocating feedback resources required for CSI feedback by each UE based on the configured downlink transmission approach and feedback mode, such that different types underlying different feedback modes for a single UE will not collide with each other within one sub-frame; and notifying each UE of the corresponding configured downlink transmission approach and feedback mode and allocated feedback resources. Further, a method of Channel State Information (CSI) feedback is provided, which comprises the following steps of: feeding downlink CSI back to a base station (BS) based on a downlink transmission approach and a feedback mode configured by the BS; and solving, when different types underlying different feedback modes collide with each other within one sub-frame, the collision based on a collision solution rule.
