Embodiment 1

[0046] Embodiment 1: The terminal establishes a connection with cell 1. Due to the increase in traffic, base station 1 adds cell 3 to the terminal according to the measurement report, and base station 1 notifies the terminal that within a specified time, such as within 5 seconds, the number of power adjustments exceeds 3 times (including 3 times) will be reported, such as image 3 shown, including the following steps:

[0047] Step 101: At time T1, the terminal reports the PHRs of all serving cells to the base station corresponding to the serving cell, that is, the terminal reports the PHRs of cell 1 and cell 3 to base station 1, and simultaneously reports the PHRs of cell 1 and cell 3 to base station 2;

[0048] Step 102: At time T2, base station 1 receives the PHR, decides to perform power control on the terminal, and notifies the terminal that the transmission power needs to be reduced;

[0049] Step 103: At time T3, base station 2 receives the PHR, decides to perform power ...

Embodiment 2

[0066] Embodiment 2: The terminal establishes a connection with cell 1. Due to the increase in traffic, base station 1 adds cell 3 to the terminal according to the measurement report, and base station 1 notifies the terminal to perform the same power adjustment times within a specified time, such as within 5 seconds. More than 2 times (including 2 times) will be reported. The same power adjustment at this time means that the power needs to be reduced, or the power needs to be increased, such as Figure 4 shown, including the following steps:

[0067] Step 201: At time T1, the terminal only reports the PHR of the relevant cell of the base station to the corresponding base station, that is, the terminal reports the PHR of cell 1 to base station 1, and at the same time reports the PHR of cell 3 to base station 2,

[0068] Step 202: At time T2, base station 1 receives the PHR, decides to perform power control on the terminal, and notifies the terminal that the transmission power ...

Embodiment 3

[0081] Embodiment 3: The terminal establishes a connection with cell 1. Due to the increase in traffic, base station 1 adds cell 3 to the terminal according to the measurement report, and base station 1 notifies the terminal that within a specified time, such as 50 milliseconds, the terminal transmit power exceeds the specified power threshold , if the maximum transmit power time exceeds 10ms, report to the base station, such as Figure 5 shown, including the following steps:

[0082] Step 301: At time T1, the terminal only reports the PHR of the relevant cell of the base station to the corresponding base station, that is, the terminal reports the PHR of cell 1 to base station 1, and simultaneously reports the PHR of cell 3 to base station 2;

[0083] Step 302: At time T2, base station 1 receives the PHR, decides to perform power control on the terminal, and notifies the terminal that the transmission power needs to be increased;

[0084] Step 303: At time T3, base station 2 ...

Abstract

Disclosed are a method for power processing and a terminal. The method comprises that: after receiving a power adjustment command, the terminal adjusts the power; and, when it is detected that a transmission power exceeds a threshold value or the time when the transmission power exceeds the threshold value in a specified time reaches a specified value or the duration when the transmission power exceeds the threshold value reaches the specified value, or it is detected that the number of the specified power adjustment commands received in the specified time exceeds a specified number, detection information is reported to a base station. With an embodiment of the present invention, the probability that the current transmission power of the terminal exceeds a maximum transmission power is reduced, or the number of power adjustments for the terminal is reduced.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a power processing method and a terminal. Background technique [0002] In the long-term evolution (LTE) system, the current transmit power of the user terminal (UE) cannot exceed the maximum transmit power of the UE. Generally, the UE shares the maximum transmit power of the UE with the current uplink through the PHR (Power Headroom Report) process. The difference in transmit power of the channel (Uplink Shared Channel, referred to as UL-SCH) is notified to the eNB (base station), and the base station performs uplink scheduling and link adaptation based on this difference, and further decides whether to perform power control (such as reducing transmit power or increasing transmit power). power, and the power that needs to be adjusted) to meet the requirement that the current transmit power of the UE cannot exceed the maximum transmit power of the UE. The PHR process is comple...
