Abstract
Provided are a parameter determination method and device for coordinated multi-point transmission. The parameter determination method includes steps described below. A first parameter is determined, and a second parameter is determined according to the first parameter. The uncertainty problem of some parameter values in the coordinated multi-point transmission in the related art is solved.
Claims20
A parameter determination method performed in a wireless terminal device, comprising:
- obtaining a first transmission parameter, the first transmission parameter comprising at least one of a codebook type of a hybrid automatic repeat request acknowledgement (HARQ-ACK), or a feedback type of HARQ-ACKs corresponding to different control resource set (CORESET) groups;
- and
- determining a second transmission parameter according to the first transmission parameter, the second transmission parameter comprising a HARQ-ACK bit set indicating where a HARQ-ACK of the PDSCH is located,
- wherein the codebook type of the HARQ-ACK comprises one of a dynamic HARQ-ACK codebook and a semi-static HARQ-ACK codebook;
- and
- wherein the feedback type of the HARQ-ACKs corresponding to the different CORESET groups comprises at least one of:
- separated HARQ-ACK feedback or joint HARQ-ACK feedback.
A electronic device comprising a memory for storing instructions and at least one processor configured to execute the instructions to:
- obtain a first transmission parameter comprising at least one of a codebook type of a hybrid automatic repeat request acknowledgement (HARQ-ACK), or a feedback type of HARQ-ACKs corresponding to different control resource set (CORESET) groups;
- and
- determine a second transmission parameter according to the first transmission parameter, the second transmission parameter comprising a HARQ-ACK bit set indicating where a HARQ-ACK of the PDSCH is located,
- wherein the codebook type of the HARQ-ACK comprises one of a dynamic HARQ-ACK codebook and a semi-static HARQ-ACK codebook;
- and
- wherein the feedback type of the HARQ-ACKs corresponding to the different CORESET groups comprises at least one of:
- separated HARQ-ACK feedback or joint HARQ-ACK feedback.
A computer-readable storage medium storing a computer program, wherein the computer program, when being executed by at least one processor, is configured to
- obtain a first transmission parameter comprising at least one of a codebook type of a hybrid automatic repeat request acknowledgement (HARQ-ACK), or a feedback type of HARQ-ACKs corresponding to different control resource set (CORESET) groups;
- and
- determine a second transmission parameter according to the first transmission parameter, the second transmission parameter comprising a HARQ-ACK bit set indicating where a HARQ-ACK of the PDSCH is located,
- wherein the codebook type of the HARQ-ACK comprises one of a dynamic HARQ-ACK codebook and a semi-static HARQ-ACK codebook;
- and
- wherein the feedback type of the HARQ-ACKs corresponding to the different CORESET groups comprises at least one of:
- separated HARQ-ACK feedback or joint HARQ-ACK feedback.
