Abstract
Embodiments of this disclosure improve the reliability of blind decoding when beamforming is used by having a user equipment (UE) receive a single downlink control information (DCI) message with different transmission and/or reception parameters. In some embodiments, a UE receives more than one set of configuration parameters, where any two sets of configuration parameters out of the more than one set of configuration parameters have at least one different parameter. The UE may receive two sets of configuration parameters each having a different transmission modes, but the same search space type. Additional examples are also provided.
Claims23
A method comprising:
- transmitting, by an apparatus via a single radio resource control (RRC) message, first configuration parameters and second configuration parameters,
- wherein the first configuration parameters and the second configuration parameters each comprise at least one of a search space type, one or more aggregation levels, or a candidate number;
- transmitting, by the apparatus, a first downlink control information (DCI) in a first physical downlink control channel (PDCCH) search space in accordance with the first configuration parameters;
- and
- transmitting, by the apparatus, a second DCI in a second PDCCH search space in accordance with the second configuration parameters, the first PDCCH search space and the second PDCCH search space being different PDCCH search spaces associated with different control resource sets, wherein the first DCI and the second DCI are associated with a same UE identifier (ID) or a same radio network temporary ID (RNTI), and wherein the first DCI and the second DCI are different instances of a single DCI.
