Abstract
This disclosure provides a power control method, including: A terminal device obtains indication information of at least one power control value of an SRS and indication information of at least one time unit set. The at least one time unit set is in one-to-one correspondence with the at least one power control value. The terminal device determines transmit power of the SRS in a first time unit set based on a first power control value corresponding to the first time unit set in the at least one time unit set. The terminal device sends the SRS to a network device in a time unit in the first time unit based on the transmit power.
Claims20
A power control method, applied to a first communication apparatus, comprising:
- obtaining indication information of at least one power control value of a sounding reference signal (SRS) and indication information of at least one time unit set in one-to-one correspondence with the at least one power control value;
- determining transmit power of the SRS in a first time unit set based on a first power control value corresponding to the first time unit set in the at least one time unit set;
- and
- sending the SRS to a network device in a time unit in the first time unit set based on the transmit power.
A power control method applied to a second communication apparatus, comprising:
- sending indication information of at least one power control value of a sounding reference signal (SRS) and indication information of at least one time unit set to a terminal device, wherein the at least one time unit set is in one-to-one correspondence with the at least one power control value, and the at least one time unit set comprises a first time unit set;
- and
- receiving the SRS from the terminal device in a time unit in the first time unit set, wherein transmit power of the SRS is determined based on a first power control value corresponding to the first time unit set, and the at least one power control value comprises the first power control value.
A communication apparatus, comprising:
- a transceiver configured to obtain indication information of at least one power control value of a sounding reference signal (SRS) and indication information of at least one time unit set in one-to-one correspondence with the at least one power control value;
- and
- a processing configured to determine transmit power of the SRS in a first time unit set based on a first power control value corresponding to the first time unit set in the at least one time unit set, wherein
- the transceiver is further configured to send the SRS to a network device in a time unit in the first time unit set based on the transmit power.
