Abstract
Systems and methodologies are described herein that facilitate efficient control decoding to facilitate management of cooperative relay operation in a wireless communication environment. As described herein, a relay node (RN) and/or another entity cooperating with a serving network node for respective users in a potentially assisted group can prune a search space of control decoding candidates corresponding to the respective users. For example, respective control decoding candidates corresponding to, e.g., common and/or user-specific search spaces, aggregation levels, control channel sizes, etc., can be eliminated from a reduced control search space based on various criteria. Further, sets of control decoding candidates corresponding to respective users not schedulable at a given time interval can be eliminated. In addition, control search space pruning can be performed in addition to or in place of increased cyclic redundancy check (CRC) protection for control information, thereby further decreasing the probability of false control detection.
