Abstract
This application provides example uplink transmit power determining methods and example terminal devices. One example method includes: determining a total transmit power of a first plurality of uplink signals located in a first time domain resource, wherein the first plurality of uplink signals include MsgA PRACH; and when the total transmit power of the first plurality of uplink signals exceeds a maximum transmit power of a terminal device, determining a transmit power of the MsgA PRACH based on a power priority of the MsgA PRACH, wherein the power priority of the MsgA PRACH is same as a power priority of Msg 1 PRACH in a primary cell.
Claims10
A communication method, comprising:
- determining a total transmit power of a first plurality of uplink signals located in a first time domain resource, wherein the first plurality of uplink signals include message A (MsgA) physical random access channel (PRACH);
- when the total transmit power of the first plurality of uplink signals exceeds a maximum transmit power of a terminal device, determining a transmit power of the MsgA PRACH based on a power priority of the MsgA PRACH, wherein the power priority of the MsgA PRACH is same as a power priority of message 1 (Msg 1) PRACH in a primary cell.
A communication apparatus, comprising:
- at least one processor configured with processor-executable instructions to perform operations comprising:
- determining a total transmit power of a first plurality of uplink signals located in a first time domain resource, wherein the first plurality of uplink signals include MsgA PRACH;
- when the total transmit power of the first plurality of uplink signals exceeds a maximum transmit power of a terminal device, determining a transmit power of the MsgA PRACH based on a power priority of the MsgA PRACH, wherein the power priority of the MsgA PRACH is same as a power priority of Msg 1 PRACH in a primary cell.
A non-transitory computer-readable storage medium storing computer instructions, that when executed by at least one processor, cause the at least one processor to perform operations comprising:
- determining a total transmit power of a first plurality of uplink signals located in a first time domain resource, wherein the first plurality of uplink signals include MsgA PRACH;
- when the total transmit power of the first plurality of uplink signals exceeds a maximum transmit power of a terminal device, determining a transmit power of the MsgA PRACH based on a power priority of the MsgA PRACH, wherein the power priority of the MsgA PRACH is same as a power priority of Msg 1 PRACH in a primary cell.
