Abstract
Provided are a downlink signal transmission method and device, which can improve signal transmission performance. The method includes: a terminal device determines the number of bits of a target information indication field in the DCI and/or the information content indicated by the target information indication field according to the configuration of CORESET group index; the terminal device transmits or receives signals scheduled by the DCI based on the number of bits of the target information indication field and/or the information content indicated by the target information indication field.
Claims12
A method for downlink signal transmission, comprising:
- determining, by a terminal device, a number of bits of a target information indication field in downlink control information (DCI) and/or an information content indicated by the target information indication field according to configurations of a Control Resource Set (CORESET) pool index;
- detecting, by the terminal device, the DCI based on the number of bits of the target information indication field in the DCI and/or the information content indicated by the target information indication field;
- and
- sending or receiving, by the terminal device, signals scheduled by the DCI according to the DCI;
- wherein determining, by the terminal device, the number of bits of the target information indication field in the DCI and/or the information content indicated by the target information indication field according to the configurations of the CORESET pool index comprises:
- determining, by the terminal device, the number of bits of the target information indication field and/or the information content indicated by the target information indication field according to a quantity of the configured CORESET pool indexes, wherein the quantity is greater than or equal to 0;
- wherein the number of bits of the target information indication field when the quantity is a first value is different from the number of bits of the target information indication field when the quantity is a second value;
- and/or
- the information content indicated by the target information indication field when the quantity is the first value is different from the information content indicated by the target information indication field when the quantity is the second value.

A terminal device, comprising a memory and a processor, wherein the processor is configured to execute instructions stored in the memory to perform following operations:
- determine a number of bits of a target information indication field in downlink control information (DCI) and/or an information content indicated by the target information indication field according to configurations of Control Resource Set (CORESET) pool index;
- detect the DCI based on the number of bits of the target information indication field in the DCI and/or the information content indicated by the target information indication field;
- and
- send or receive signals scheduled by the DCI according to the DCI;
- wherein the processor is further configured to execute instructions stored in the memory to perform following operation:
- determine the number of bits of the target information indication field and/or the information content indicated by the target information indication field according to a quantity of configured CORESET pool indexes, wherein the quantity is greater than or equal to 0;
- when the CORESET pool index is not comprised in parameters of any CORESET configured for the terminal device, the quantity of the CORESET pool indexes is 0;
- and/or
- when all the CORESET pool indexes comprised in the parameters of the CORESETs configured for the terminal device are 0 or when all the CORESET pool indexes comprised in the parameters of the CORESETs configured for the terminal device are 1, the quantity of the CORESET pool indexes is 1;
- and/or
- when the CORESET pool indexes comprised in the parameters of a portion of the CORESETs configured for the terminal device are 0, and the CORESET pool indexes comprised in the parameters of another portion of the CORESETs configured for the terminal device are 1, the quantity of CORESET pool indexes is 2;
- wherein:
- the number of bits of the target information indication field when the quantity is a first value is different from the number of bits of the target information indication field when the quantity is a second value;
- and/or
- the information content indicated by the target information indication field when the quantity is the first value is different from the information content indicated by the target information indication field when the quantity is the second value.
