Abstract

Apparatuses, methods, and systems are disclosed for transmitting information for PDSCH configurations. One method ( 400 ) includes determining ( 402 ) configuration information comprising a plurality of instances of a physical downlink shared channel configuration parameter. The method ( 400 ) includes transmitting ( 404 ) the configuration information to a user equipment, wherein: the physical downlink shared channel configuration parameter is used for a physical downlink shared channel scheduled by downlink control information; the downlink control information is transmitted from a set of resources having a corresponding index of a plurality of indexes; and each index corresponds to an instance of the plurality of instances of the physical downlink shared channel configuration parameter.

Claims (42)

1 . A method performed by a base station, the method comprising:

determining configuration information comprising a plurality of instances of a same physical downlink shared channel (PDSCH) configuration parameter within a single PDSCH configuration, and a mapping of each instance of the plurality of instances of the PDSCH configuration parameter to a corresponding index of a plurality of indexes comprising control resource set (CORESET) pool indexes; and

transmitting the configuration information to a user equipment (UE), wherein:

the PDSCH configuration parameter is used for a PDSCH scheduled by downlink control information (DCI);

the DCI is transmitted from a set of resources having a corresponding index of a plurality of indexes; and

the corresponding index of the set of resources indicates to the UE to select, for use, the single corresponding instance of the plurality of instances of the PDSCH configuration parameter based on a CORESET pool index of a resource of the set of resources from which the DCI is transmitted,

wherein, in response to the configuration information omitting a mapping between the plurality of instances of the PDSCH configuration parameter and the plurality of indexes, the base station maps the plurality of instances of the PDSCH configuration parameter to the plurality of indexes in ascending order of the indexes.

2 . A base station, comprising:

a memory; and

at least one processor coupled with the memory and configured to cause the base station to:

determine configuration information comprising a plurality of instances of a same physical downlink shared channel (PDSCH) configuration parameter within a single PDSCH configuration, and a mapping of each instance of the plurality of instances of the PDSCH configuration parameter to a corresponding index of a plurality of indexes comprising control resource set (CORESET) pool indexes; and

transmit the configuration information to a user equipment (UE), wherein:

the PDSCH configuration parameter is used for a PDSCH scheduled by downlink control information (DCI);

the DCI is transmitted from a set of resources having a corresponding index of a plurality of indexes; and

the corresponding index of the set of resources indicates to the UE to select, for use, the single corresponding instance of the plurality of instances of the PDSCH configuration parameter based on a CORESET pool index of a resource of the set of resources from which the DCI is transmitted,

wherein, in response to the configuration information omitting a mapping between the plurality of instances of the PDSCH configuration parameter and the plurality of indexes, the base station maps the plurality of instances of the PDSCH configuration parameter to the plurality of indexes in ascending order of the indexes.

3 . The base station of claim 2 , wherein each index of the plurality of indexes corresponds to at least one control resource set.

4 . The base station of claim 2 , wherein the configuration information comprises a plurality of instances of selected PDSCH configuration parameters of a plurality of PDSCH configuration parameters.

5 . The base station of claim 2 , wherein the plurality of instances of the PDSCH configuration parameter is part of a single PDSCH configuration.

6 . The base station of claim 5 , wherein one instance of at least one PDSCH configuration parameter corresponds to the plurality of indexes.

7 . The base station of claim 5 , wherein the single PDSCH configuration comprises a list of the plurality of indexes, and instances of the plurality of instances of the PDSCH configuration parameter are mapped to the indexes in the list of the plurality of indexes.

8 . The base station of claim 5 , wherein, in response to the configuration information not mapping instances of the plurality of instances of the PDSCH configuration parameter to the plurality of indexes, the instances of the plurality of instances of the PDSCH configuration parameter are mapped to the plurality of indexes in ascending order.

9 . The base station of claim 2 , wherein each instance of the plurality of instances of the PDSCH configuration parameter is in a separate PDSCH configuration.

10 . The base station of claim 9 , wherein the separate PDSCH configuration comprises an index of the plurality of indexes.

11 . The base station of claim 9 , wherein, in response to the separate PDSCH configuration not comprising an index of the plurality of indexes, the separate PDSCH configuration is mapped to the plurality of indexes in ascending order.

12 . The base station of claim 2 , wherein the configuration information comprises one or more PDSCH configuration parameters comprising dataScramblingIdentityPDSCH, dmrs-DownlinkForPDSCH-MappingTypeA, dmrs-DownlinkForPDSCH-MappingTypeB, tci-StatesToAddModList, tci-StatesToReleaseList, resourceAllocation, pdsch-TimeDomainAllocationList, pdsch-AggregationFactor, rbg-Size, mcs-Table, prb-BundleSize, or some combination thereof.

13 . A user equipment (UE), comprising:

at least one memory; and

at least one processor coupled with the at least one memory and configured to cause the UE to:

receive configuration information from a base station, wherein:

the configuration information comprising a plurality of instances of a same physical downlink shared channel (PDSCH) configuration parameter within a single PDSCH configuration, and a mapping of each instance of the plurality of instances of the PDSCH configuration parameter to a corresponding index of a plurality of indexes comprising control resource set (CORESET) pool indexes;

the PDSCH configuration parameter is used for a PDSCH scheduled by downlink control information (DCI);

the DCI is transmitted from a set of resources having a corresponding index of a plurality of indexes; and

the corresponding index of the set of resources indicates to the UE to select, for use, the single corresponding instance of the plurality of instances of the PDSCH configuration parameter based on a CORESET pool index of a resource of the set of resources from which the DCI is transmitted,

wherein, in response to the configuration information omitting a mapping between the plurality of instances of the PDSCH configuration parameter and the plurality of indexes, the UE applies a mapping determined according to a rule that associates the plurality of instances with the plurality of indexes in ascending order of the indexes.

14 . The UE of claim 13 , wherein each index of the plurality of indexes corresponds to at least one control resource set.

15 . The UE of claim 13 , wherein the configuration information comprises a plurality of instances of selected PDSCH configuration parameters of a plurality of PDSCH configuration parameters.

16 . The UE of claim 13 , wherein the plurality of instances of the PDSCH configuration parameter is part of a single PDSCH configuration.

17 . The UE of claim 16 , wherein one instance of at least one PDSCH configuration parameter corresponds to the plurality of indexes.

18 . The UE of claim 16 , wherein the single PDSCH configuration comprises a list of the plurality of indexes, and instances of the plurality of instances of the PDSCH configuration parameter are mapped to the indexes in the list of the plurality of indexes.

19 . The UE of claim 16 , wherein the at least one processor, in response to the configuration information not mapping instances of the plurality of instances of the PDSCH configuration parameter to the plurality of indexes, maps the instances of the plurality of instances of the PDSCH configuration parameter to the plurality of indexes in ascending order.

20 . The UE of claim 13 , wherein each instance of the plurality of instances of the PDSCH configuration parameter is in a separate PDSCH configuration.
