Embodiment 1

[0066] The terminal establishes a connection with cell 1, which is the main serving cell. Figure 9 It is a flow chart of the PHR triggering method according to Embodiment 1 of the present invention, such as Figure 9 As shown, the method includes the following steps:

[0067] Step S902, the terminal establishes a connection with cell 1;

[0068] Step S904, due to the increase in traffic, the base station adds cell 3 to the terminal according to the measurement report. Cell 3 is an unlicensed carrier and needs to obtain resource usage rights through competition. Cell 3 is a secondary serving cell. The terminal receives the configuration of cell 3 Information, add cell 3;

[0069] Step S906, the base station initiates a resource competition process in cell 3 according to the demand of terminal traffic;

[0070] Step S908, after the base station competes for the resources of the cell 3, it starts to schedule the terminal to send and receive data in the cell 3;

[0071]Step S...

Embodiment 2

[0075] The terminal establishes a connection with cell 1, which is the main serving cell. Figure 10 It is a flow chart of the PHR triggering method according to Embodiment 2 of the present invention, such as Figure 10 As shown, the method includes the following steps:

[0076] Step S1002, the terminal establishes a connection with cell 1;

[0077] Step S1004, due to the increase in traffic volume, base station 1 adds cell 3 to the terminal according to the measurement report. Cell 3 is an unlicensed carrier and needs to obtain resource usage rights through competition. Cell 3 is a secondary serving cell, and the terminal receives cell 3. Configure information, add cell 3;

[0078] Step S1006, the base station initiates a resource competition process in cell 3 according to the demand of terminal traffic;

[0079] Step S1008, after the base station competes for the resources of cell 3, it sends configuration information to the terminal, including the resource usage mode for...

Embodiment 3

[0083] The terminal establishes a connection with cell 1, which is the main serving cell. Figure 11 It is a flow chart of the PHR triggering method according to Embodiment 3 of the present invention, such as Figure 11 As shown, the method includes the following steps:

[0084] Step S1102, the terminal establishes a connection with cell 1;

[0085] Step S1104, due to the increase in traffic volume, base station 1 adds cell 3 to the terminal according to the measurement report, cell 3 is an unlicensed carrier, and needs to obtain resource usage rights through competition, cell 3 is a secondary serving cell, and the terminal receives cell 3 Configure information, add cell 3;

[0086] Step S1106, the terminal initiates a resource competition process in cell 3 according to the demand of traffic volume;

[0087] Step S1108, the terminal notifies the base station to perform the resource competition process of cell 3;

[0088] Step S1110, the terminal competes for resources in c...

Abstract

This invention provides a power headroom report (PHR) processing method and device, and a terminal and a base station. The method comprises the steps of: determining that a triggering condition used for triggering the PHR is satisfied; and triggering the PHR according to the triggering condition. The triggering condition comprises at least one of: at a first time for sending and / or receiving data on an unauthorized carrier, a first data scheduling time sent by the base station is received, and a competition command which is sent by the base station and used for competing for unauthorized carrier resource is received. By adoption of the method, the problem that the base station cannot learn the PHR timely in the unauthorized carrier scene can be solved; and therefore, the PHR can be learnt in the unauthorized carrier scene timely.

Description

technical field [0001] The present invention relates to the communication field, in particular to a power headroom reporting PHR processing method, device, terminal and base station. Background technique [0002] In the Long-Term Evolution (LTE for short) system, the current transmission power of the user equipment (User Equipment, UE for short) cannot exceed the maximum transmission power of the UE. Generally, the UE reports through the power headroom report (power headroom report, PHR for short) process notifies the base station of the difference between the maximum transmit power of the UE and the transmit power of the current uplink shared channel (Uplink Shared Channel, UL-SCH) and the physical uplink control channel (Physical Uplink Control Channel), and the base station performs uplink according to this difference Scheduling and link adaptation, and further decide whether to perform power control (such as reducing or increasing transmit power, and the power level that...
