Method and device for reporting configurable maximum transmission power of UE carrier

A User Equipment (UE), comprising:

• a judging module that judges whether to report a configurable maximum transmission power of a UE carrier to a base station through a format of a Power Headroom Report Medium Access Control Control Element (PHR MAC CE) carrying the configurable maximum transmission power of the UE carrier, the judging module judging according to a current network configuration, according to an indication message sent by the base station and received by a communication module of the UE, according to indication information carried in Radio Resource Control (RRC) signaling or Medium Access Control (MAC) signaling sent by the base station and received by the communication module, or according to whether the UE supports Carrier Aggregation (CA) transmission, whereby:
• the UE makes a judgment to report when:
• a number of a cell the base station configures for the UE in a cell assembly or a cell activated is greater than 1, or
• the number of the cell the base station configures for the UE in the cell assembly is equal to 1, and the UE and base station allow parallel transmission of Physical Uplink Control Channel (PUCCH) and Physical Uplink Shared Channel (PUSCH), or the UE and base station support discontinuous PUSCH transmission or the UE supports the discontinuous PUSCH transmission, and
• the UE makes a judgment to not report when:
• the number of the cell the base station configures for the UE in the cell assembly is equal to 1, and the UE and base station do not allow parallel transmission of PUCCH and PUSCH;
• a power determination module that is used to determine the configurable maximum transmission power of the UE carrier when the judging module makes the judgment to report the configurable maximum transmission power;
• a mode determination module that is used to determine a way of carrying the configurable maximum transmission power of the UE carrier in the PHR MAC CE according to a current Uplink (UL) transmission configuration;
• and
• the communication module that is used to report the configurable maximum transmission power of the UE carrier to the base station through the PHR MAC CE according to a realization mode determined by the mode determination module.

A method for reporting a configurable maximum transmission power of a User Equipment (UE) carrier, comprising:

• a UE judging whether to report the configurable maximum transmission power of the UE carrier to a base station through a format of a Power Headroom Report Medium Access Control Control Element (PHR MAC CE) carrying the configurable maximum transmission power of the UE carrier, and when a judgment is made to report:
• the UE determining the configurable maximum transmission power of the UE carrier, whereby:
• for a cell requiring reporting Power Headroom Type 1 (Type 1 PH), the UE determines the configurable maximum transmission power of the UE carrier used to calculate the Type 1 PH of the cell according to an impact of an Additional Maximum Power Reduction/Maximum Power Reduction (A-MPR/MPR) caused by real Physical Uplink Shared Channel (PUSCH) transmission in all cells, and
• for a Parameterized Cell (PCell) requiring reporting Power Headroom Type 2 (Type 2 PH), the UE determines the configurable maximum transmission power of the UE carrier used to calculate the Type 2 PH of the cell according to the impact of the A-MPR/MPR caused by real PUSCH and Physical Uplink Control Channel (PUCCH) transmission in all cells;
• the UE determining a way of carrying the configurable maximum transmission power of the UE carrier in the PHR MAC CE according to a current Uplink (UL) transmission configuration;
• and
• the UE reporting the configurable maximum transmission power of the UE carrier to the base station through the PHR MAC CE according to a realization mode.
