Abstract

The disclosure discloses a method for downlink control information (DCI) design, an electronic device, and a storage medium. The method for design includes: configuring transmission configuration indicator (TCI) state information of a control channel through a DCI.

First claim

What is claimed is:

1 . A method for downlink control information (DCI) design, comprising:
configuring transmission configuration indicator (TCI) state information of a control channel through a DCI, wherein when the DCI is a common DCI, configuring the TCI state information of the control channel through the DCI comprises:
indicating TCI state information of each first control resource set (CORESET) corresponding to each information block in the common DCI dynamically; and/or
indicating TCI state information of each first physical uplink control channel (PUCCH) resource corresponding to each information block in the common DCI dynamically, wherein
each user equipment (UE) corresponds to one information block; or
wherein when the DCI is a dedicated DCI, configuring the TCI state information of the control channel through the DCI comprises:
indicating TCI state information of each second CORESET corresponding to the dedicated DCI dynamically,
wherein the dedicated DCI corresponds to one UE.

2 . The method of claim 1 , wherein when the DCI is the common DCI, and the method further comprises:
determining a first valid time corresponding to the configured TCI state information, wherein the first valid time is calculated according to a time slot in which a physical downlink control channel (PDCCH) is received and a predefined time sequence.

3 . The method of claim 2 , wherein after configuring the TCI state information of the control channel through the DCI, the method further comprises:
when configuration of the TCI state information of the control channel through a medium access control (MAC) control element (CE) is valid,
determining that configuration or a configuration manner of the TCI state information of the control channel through the DCI is invalid; and
determining the TCI state information configured through the MAC CE as the TCI state information of the control channel.

4 . The method of claim 1 , wherein when the DCI is the dedicated DCI, and the method further comprises:
determining a second valid time corresponding to the configured TCI state information, wherein the second valid time is calculated according to a time slot in which a PDCCH is received and a predefined time sequence, or the second valid time is a time when the UE transmits a feedback signal to a network-side device.

5 . The method of claim 4 , wherein the feedback signal transmitted by the UE to the network-side device comprises hybrid automatic repeat request (HARQ)-acknowledgement (ACK) feedback information generated by the UE based on the received DCI.

6 . The method of claim 4 , wherein after configuring the TCI state information of the control channel through the DCI, the method further comprises:
when configuration of the TCI state information of the control channel through a MAC CE is valid,
determining that configuration or a configuration manner of the TCI state information of the control channel through the DCI is invalid; and
determining the TCI state information configured through the MAC CE as the TCI state information of the control channel.

7 . An electronic device, comprising:
a memory configured to store computer programs; and a processor configured to invoke and execute the computer programs stored in the memory to:
configure transmission configuration indicator (TCI) state information of a control channel through a DCI,
wherein when the DCI is a common DCI, the processor configured to configure the TCI state information of the control channel through the DCI is configured to:
indicate TCI state information of each first control resource set (CORESET) corresponding to each information block in the common DCI dynamically; and/or
indicate TCI state information of each first physical uplink control channel (PUCCH) resource corresponding to each information block in the common DCI dynamically, wherein
each user equipment (UE) corresponds to one information block; or

wherein when the DCI is a dedicated DCI, the processor configured to configure the TCI state information of the control channel through the DCI is configured to:
indicate TCI state information of each second CORESET corresponding to the dedicated DCI dynamically,
wherein the dedicated DCI corresponds to one UE.

8 . The electronic device of claim 7 , wherein when the DCI is the common DCI, the processor is further configured to invoke and execute the computer programs stored in the memory to:
determine a first valid time corresponding to the configured TCI state information, wherein the first valid time is calculated according to a time slot in which a physical downlink control channel (PDCCH) is received and a predefined time sequence.

9 . The electronic device of claim 7 , wherein when the DCI is the dedicated DCI, the processor is further configured to invoke and execute the computer programs stored in the memory to:
determine a second valid time corresponding to the configured TCI state information, wherein the second valid time is calculated according to a time slot in which a PDCCH is received and a predefined time sequence, or the second valid time is a time when the UE transmits a feedback signal to a network-side device.

10 . The electronic device of claim 9 , wherein the feedback signal transmitted by the UE to the network-side device comprises hybrid automatic repeat request (HARQ)-acknowledgement (ACK) feedback information generated by the UE based on the received DCI.

11 . The electronic device of claim 7 , wherein when the DCI is the common DCI, the processor is further configured to invoke and execute the computer programs stored in the memory to:
when configuration of the TCI state information of the control channel through a medium access control (MAC) control element (CE) is valid,
determine that configuration or a configuration manner of the TCI state information of the control channel through the DCI is invalid; and
determine the TCI state information configured through the MAC CE as the TCI state information of the control channel.

12 . The electronic device of claim 7 , wherein when the DCI is the dedicated DCI, the processor is further configured to invoke and execute the computer programs stored in the memory to:
when configuration of the TCI state information of the control channel through a MAC CE is valid,
determine that configuration or a configuration manner of the TCI state information of the control channel through the DCI is invalid; and
determine the TCI state information configured through the MAC CE as the TCI state information of the control channel.

13 . A non-transitory computer-readable storage medium storing computer programs which, when executed by an electronic device, are configured to cause the electronic device to:
configure transmission configuration indicator (TCI) state information of a control channel through a DCI, wherein when the DCI is a common DCI, the computer programs causing the electronic device to configure the TCI state information of the control channel through the DCI cause the electronic device to:
indicate TCI state information of each first control resource set (CORESET) corresponding to each information block in the common DCI dynamically; and/or
indicate TCI state information of each first physical uplink control channel (PUCCH) resource corresponding to each information block in the common DCI dynamically, wherein
each user equipment (UE) corresponds to one information block; or
wherein when the DCI is a dedicated DCI, the computer programs causing the electronic device to configure the TCI state information of the control channel through the DCI ca
