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.
Claims26
A method comprising:
- receiving, by a user equipment (UE), a single radio resource control (RRC) message;
- monitoring, by the UE, a first physical downlink control channel (PDCCH) search space for a first downlink control information (DCI) in accordance with first configuration parameters included in the single RRC message;
- and
- monitoring, by the UE, a second PDCCH search space for a second DCI in accordance with second configuration parameters included in the single RRC message, the first PDCCH search space and the second PDCCH search space being associated with different control resource sets, wherein the first configuration parameters and the second configuration parameters each comprise a reception beam index, wherein the first DCI and the second DCI are associated with a same UE identifier (ID), and wherein the first PDCCH search space and the second PDCCH search space are different UE-specific search spaces.
An apparatus comprising:
- at least one processor;
- and
- a non-transitory computer readable storage medium storing programming for execution by the at least one processor, the programming including instructions to cause the apparatus to:
- receive single radio resource control (RRC) message;
- monitor a first physical downlink control channel (PDCCH) search space for a first downlink control information (DCI) in accordance with first configuration parameters included in the single RRC message;
- and
- monitor a second PDCCH search space for a second DCI in accordance with second configuration parameters included in in the single RRC message, the first PDCCH search space and the second PDCCH search space being associated with different control resource sets, wherein the first configuration parameters and the second configuration parameters each comprise a reception beam index, wherein the first DCI and the second DCI are associated with a same user equipment (UE) identifier (ID), and wherein the first PDCCH search space and the second PDCCH search space are different UE-specific search spaces.
A non-transitory computer readable storage medium storing instructions that, when executed by an apparatus, cause the apparatus to:
- receive a single radio resource control (RRC) message;
- monitor a first physical downlink control channel (PDCCH) search space for a first downlink control information (DCI) in accordance with first configuration parameters included in the single RRC message;
- and
- monitor a second PDCCH search space for a second DCI in accordance with second configuration parameters included in the single RRC message, the first PDCCH search space and the second PDCCH search space being associated with different control resource sets, wherein the first configuration parameters and the second configuration parameters each comprise a reception beam index, wherein the first DCI and the second DCI are associated with a same user equipment (UE) identifier (ID), and wherein the first PDCCH search space and the second PDCCH search space are different UE-specific search spaces.
