Embodiment approach

[0050] As another optional implementation manner, the specific path loss reference includes:

[0051] The path loss reference corresponding to the first time or the second time, wherein the first time is the time when the terminal triggers a PHR report (PHR trigger), and the second time is the time when the terminal generates a PDU including PHR .

[0052] The aforementioned time of generating the PDU including the PHR may be the time of generating a MAC PDU (PHR MAC PDUAssembly) including the PHR.

[0053] The above-mentioned path loss reference corresponding to the first time may be determined according to the first time, and there is a path loss reference with a specific relationship at the first time, for example: the path loss reference corresponding to the first time includes: The path loss reference used by time. Wherein, when the path loss reference is not changed at the first time, the path loss reference used at the first time may include: the path loss reference u...

Abstract

Embodiments of the present invention provide a PH calculation method and a terminal, the method includes: receiving a path loss reference change indication; calculating PH using a specific path loss reference, wherein the specific path loss reference includes the change of the path loss reference change indication The previous path loss reference, or the change of the path loss reference indicates a changed path loss reference. In this way, the performance of reporting the PH by the terminal can be improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method for calculating a power headroom (Power Headroom, PH) and a terminal. Background technique [0002] In a communication system, a terminal needs to report a Power Headroom Report (PHR). The PHR includes PH. The PH can also be called the cell power headroom. Of course, the PHR can also include the maximum transmit power of the cell (Pcmax. c). Among them, PH is calculated by the terminal according to the value measured by the path loss reference (Path loss reference), and the path loss reference in the current communication system is pre-configured for the terminal, that is to say, the path loss reference obtained by the terminal is always does not change, which leads to poor performance in reporting PH. Contents of the invention [0003] Embodiments of the present invention provide a PH calculation method and a terminal, so as to solve the problem...
