Abstract

A method for transmitting power information is performed by a terminal, and includes: transmitting power information to a network device; wherein the power information corresponds to an uplink panel of the terminal or an uplink beam of the terminal.

Claims (75)

1 . A method for transmitting power information, performed by a terminal, comprising:

determining that a power management-maximum power reduction (P-MPR) value corresponding to an uplink panel or an uplink beam of the terminal is not less than a maximum permissible exposure (MPE) threshold; and

transmitting power information to a network device;

wherein the power information corresponds to the uplink panel of the terminal or the uplink beam of the terminal,

wherein the power information comprises at least one of:

panel identification information of the uplink panel, and at least one of a P-MPR measurement value or a power headroom value corresponding to the uplink panel; or

beam identification information of the uplink beam, and at least one of a P-MPR measurement value or a power headroom value corresponding to the uplink beam.

2 . The method of claim 1 , wherein the power information comprises at least one of:

n panel identifications and n pieces of first bit indication information, wherein an i-th piece of first bit indication information indicates whether a P-MPR value corresponding to an i-th uplink panel of the terminal is less than the MPE threshold; or

m beam identifications and m pieces of second bit indication information, wherein a j-th piece of second bit indication information indicates whether a P-MPR value corresponding to a j-th uplink beam of the terminal is less than the MPE threshold;

wherein n and m are both positive integers, i is a positive integer not greater than n, and j is a positive integer not greater than m.

3 . The method of claim 2 , wherein the power information further comprises third bit indication information;

wherein the third bit indication information indicates the P-MPR measurement value corresponding to the uplink panel or the uplink beam.

4 . The method of claim 1 , further comprising:

transmitting beam measurement information to the network device;

wherein the beam measurement information corresponds to the uplink panel of the terminal, or the uplink beam of the terminal.

5 . The method of claim 1 , wherein the panel identification information comprises at least one of:

a panel identification;

an identification of a reference signal set;

an identification of a reference signal;

an identification of a transmission configuration indication (TCI) state; or

an identification of spatial relationship information.

6 . The method of claim 1 , wherein the beam identification information comprises at least one of:

an identification of a reference signal;

an identification of a TCI state; or

an identification of spatial relationship information.

7 . The method of claim 5 , wherein the reference signal comprises at least one of:

a channel state information-reference signal (CSI-RS);

a synchronous signal block (SSB); or

a sounding reference signal (SRS).

8 . A method for receiving power information, performed by a network device, comprising:

determining that a power management-maximum power reduction (P-MPR) value corresponding to an uplink panel or an uplink beam of a terminal is not less than a maximum permissible exposure (MPE) threshold; and

receiving power information transmitted by a terminal;

wherein the power information corresponds to the uplink panel of the terminal or the uplink beam of the terminal;

wherein the power information comprises at least one of:

panel identification information of the uplink panel, and at least one of a P-MPR measurement value or a power headroom value corresponding to the uplink panel; or

beam identification information of the uplink beam, and at least one of a P-MPR measurement value or a power headroom value corresponding to the uplink beam.

9 . The method of claim 8 , wherein the power information comprises at least one of:

n panel identifications and n pieces of first bit indication information, wherein an i-th piece of first bit indication information indicates whether a P-MPR value corresponding to an i-th uplink panel of the terminal is less than the MPE threshold; or

m beam identifications and m pieces of second bit indication information, wherein a j-th piece of second bit indication information indicates whether a P-MPR value corresponding to a j-th uplink beam of the terminal is less than the MPE threshold;

wherein n and m are both positive integers, i is a positive integer not greater than n, and j is a positive integer not greater than m.

10 . The method of claim 9 , wherein the power information further comprises third bit indication information;

wherein the third bit indication information indicates the P-MPR measurement value corresponding to the uplink panel or the uplink beam.

11 . The method of claim 8 , wherein the panel identification information comprises at least one of:

a panel identification;

an identification of a reference signal set;

an identification of a reference signal;

an identification of a transmission configuration indication (TCI) state; or

an identification of spatial relationship information.

12 . The method of claim 8 , wherein the beam identification information comprises at least one of:

an identification of a reference signal;

an identification of a TCI state; or

an identification of spatial relationship information.

13 . The method of claim 11 , wherein the reference signal comprises at least one of:

a channel state information-reference signal (CSI-RS);

a synchronous signal block (SSB); or

a sounding reference signal (SRS).

14 . The method of claim 8 , further comprising:

performing uplink scheduling according to the power information,

wherein performing uplink scheduling comprises:

determining a target beam, wherein the target beam is used by the terminal to transmit at least one of: an uplink TCI state, a spatial setting, or spatial relationship information.

15 . A terminal, comprising:

a processor; and

a memory having at least one program code stored therein;

wherein the processor is configured to:

determine that a power management-maximum power reduction (P-MPR) value corresponding to an uplink panel or an uplink beam of a terminal is not less than a maximum permissible exposure (MPE) threshold; and

transmit power information to a network device;

wherein the power information corresponds to the uplink panel of the terminal or the uplink beam of the terminal;

wherein the power information comprises at least one of:

panel identification information of the uplink panel, and at least one of a P-MPR measurement value or a power headroom value corresponding to the uplink panel; or

beam identification information of the uplink beam, and at least one of a P-MPR measurement value or a power headroom value corresponding to the uplink beam.

16 . A network device, comprising:

a processor; and

a memory having at least one program code stored therein;

wherein the processor is configured to perform the method of claim 8 .
