Abstract
A user terminal according to an aspect of the present disclosure includes a transmitting/receiving section that performs at least one of transmission and reception of a demodulation reference signal (DMRS) for a physical shared channel, and a control section that determines a power for the DMRS without taking account of a resource element to which the DMRS is not allocated, with reference to a table providing a definition of a ratio of a power (EPRE) for each resource element of the physical shared channel to an EPRE for the DMRS to which a certain number of CDM groups is applied. According to one aspect of the present disclosure, it is possible to use the same transmission power for data symbols and DMRS symbols even in NR.
Claims4
A terminal comprising:
- a control section that determines a power for a demodulation reference signal (DMRS) for a physical shared channel without taking account of any resource element (RE) to which the DMRS is not allocated, according to a ratio of energy per resource element (EPRE) of the physical shared channel to an EPRE for the DMRS to which a number of code division multiplexing (CDM) groups without data is applied;
- and
- a transmitting/receiving section that performs at least one of transmission and reception of the DMRS based on the power for the DIMS.
A radio communication method for a terminal comprising:
- determining a power for a demodulation reference signal (DMRS) for a physical shared channel without taking account of any resource element (RE) to which the DMRS is not allocated, according to a ratio of energy per resource element (EPRE) of the physical shared channel to an EPRE for the DMRS to which a number of code division multiplexing (CDM) groups without data is applied;
- and
- performing at least one of transmission and reception of the DMRS based on the power for the DMRS.
A base station comprising:
- a control section that determines a power for a demodulation reference signal (DMRS) for a physical shared channel without taking account of any resource element (RE) to which the DMRS is not allocated, according to a ratio of energy per resource element (EPRE) of the physical shared channel to an EPRE for the DMRS to which a number of code division multiplexing (CDM) groups without data is applied;
- and
- a transmitting/receiving section that performs at least one of transmission and reception of the DMRS on the power for the DMRS.
