Abstract
A method for determining an overhead reference value for DMRS and a terminal are provided. The method includes: determining an overhead reference value for DMRS based on first information, where the first information includes at least one of PSFCH configuration information, SCI, and higher-layer signaling configuration information, and the overhead reference value includes a time-domain overhead reference value and a frequency-domain overhead reference value.

A method for determining an overhead reference value for demodulation reference signal (DMRS), applied to a terminal and comprising:
- determining an overhead reference value for DMRS based on first information, wherein the first information comprises at least one of physical sidelink feedback channel (PSFCH) configuration information, sidelink control information (SCI), or higher-layer signaling configuration information, and the overhead reference value comprises a time-frequency domain overhead reference value,
- wherein the time-frequency domain overhead reference value for the DMRS is determined based on a pattern of the DMRS,
- when the pattern of the DMRS is a DMRS pattern configured by using higher-layer signaling, the time-frequency domain overhead reference value for the DMRS is an average value of a number of symbols for all DMRS patterns configured by using the higher-layer signaling.
A terminal, comprising a processor, a memory, and a program stored in the memory and capable of running on the processor, wherein when the program is executed by the processor, the following steps are implemented:
- determining an overhead reference value for DMRS based on first information, wherein the first information comprises at least one of physical sidelink feedback channel (PSFCH) configuration information, sidelink control information (SCI), or higher-layer signaling configuration information, and the overhead reference value comprises a time-frequency domain overhead reference value,
- wherein the time-frequency domain overhead reference value for the DMRS is determined based on a pattern of the DMRS,
- when the pattern of the DMRS is a DMRS pattern configured by using higher-layer signaling, the time-frequency domain overhead reference value for the DMRS is an average value of a number of symbols for all DMRS patterns configured by using the higher-layer signaling.
A non-transitory computer-readable storage medium, wherein the non-transitory computer-readable storage medium stores a program, and when the program is executed by a processor, the following steps are implemented:
- determining an overhead reference value for DMRS based on first information, wherein the first information comprises at least one of physical sidelink feedback channel (PSFCH) configuration information, sidelink control information (SCI), or higher-layer signaling configuration information, and the overhead reference value comprises a time-frequency domain overhead reference value,
- wherein the time-frequency domain overhead reference value for the DMRS is determined based on a pattern of the DMRS,
- when the pattern of the DMRS is a DMRS pattern configured by using higher-layer signaling, the time-frequency domain overhead reference value for the DMRS is an average value of a number of symbols for all DMRS patterns configured by using the higher-layer signaling.
