SEARCH SPACES FOR WIRELESS COMMUNICATIONS

摘要

Methods and apparatuses for providing adaptive search space definitions for wireless communications are provided where a code rate available for at least one selected downlink control information format is determined based on a determined control channel element size and an evaluation is performed whether said code rate is acceptable for transmission of control information. When said code rate is acceptable, at least one search space candidate is defined based on said control channel element size and code rate. When said code rate is unacceptable, iterative evaluation is provided whether a code rate determined on a higher aggregation level is acceptable.
