Information transmission method, apparatus and device

A terminal, comprising a transceiver, a storage, a processor and a computer program stored on the storage and executable by the processor,

• wherein the transceiver is configured to receive downlink transmission,
• the processor is configured to execute the computer program to identify a transmission reception point (TRP) or a TRP group corresponding to the downlink transmission;
• the transceiver is further configured to transmit a Hybrid Automatic Repeat request Acknowledge (HARQ-ACK) of the downlink transmission to the TRP or the TRP group corresponding to the downlink transmission through a Physical Uplink Control Channel (PUCCH), wherein,
• HARQ-ACKs corresponding to downlink transmissions of different TRPs or TRP groups are transmitted on different PUCCHs;
• different PUCCHs are PUCCHs using different PUCCH resources or PUCCHs transmitted on non-overlapping symbols on the same carrier, or PUCCHs transmitted on different carriers.

The network device according to claim 4038, wherein,

• in the second manner, the processor is further configured to execute the computer program to:
• if the group of PUCCH resource sets corresponding to the TRP or the TRP group corresponding to the downlink transmission comprises only one PUCCH resource set, then according to DCI corresponding to the downlink transmission, determine, in the PUCCH resource set, the PUCCH resource for carrying the HARQ-ACK of the downlink transmission;
• if the group of PUCCH resource sets corresponding to the TRP or the TRP group corresponding to the downlink transmission comprises at least two PUCCH resource sets, then select one PUCCH resource set according to the number of UCI bits to be fed back, and determine, in the selected one PUCCH resource set according to DCI corresponding to the downlink transmission, the PUCCH resource for carrying the HARQ-ACK of the downlink transmission;
• or,
• in the second manner, the processor is further configured to execute the computer program to:
• if the configuration signaling configures only one PUCCH resource set, then according to preset correspondence relationship between a TRP or a TRP group and a PUCCH resource in the one PUCCH resource set, determine, in the PUCCH resource set, one or more PUCCH resources corresponding to the TRP or the TRP group corresponding to the downlink transmission as candidate PUCCH resources, and according to DCI corresponding to the downlink transmission, determine, from the candidate PUCCH resources, the PUCCH resource for carrying the HARQ-ACK of the downlink transmission;
• if the configuration signaling configures at least two PUCCH resource sets, then select one PUCCH resource set according to the number of UCI bits to be fed back, and according to preset correspondence relationship between a TRP or a TRP group and a PUCCH resource in the selected one PUCCH resource set, determine, in the selected one PUCCH resource set, one or more PUCCH resources corresponding to the TRP or the TRP group corresponding to the downlink transmission as candidate PUCCH resources, and according to the DCI corresponding to the downlink transmission;
• determine, from the candidate PUCCH resources, the PUCCH resource for carrying the HARQ-ACK of the downlink transmission.
