Abstract
A method and apparatus for reporting a maximum carrier power in a carrier aggregation scenario are disclosed. The method includes: a user equipment (UE) encapsulating a particular power headroom (PH) of an activated uplink component carrier (UL CC) and a particular maximum output power of a physical channel of the activated UL CC into a same power headroom report (PHR) and reporting the PHR to a base station (eNB). The method enables the eNB to acquire the power situation of the UE in time so as to perform scheduling more accurately.

A method for reporting a maximum carrier power in a carrier aggregation scenario, comprising:
- a user equipment (UE) encapsulating a particular power headroom (PH) of an activated uplink component carrier (UL CC) and a particular maximum output power of a physical channel of the activated UL CC into a same power headroom report (PHR) and reporting the PHR to a base station (eNB), wherein the step of the UE encapsulating the particular PH of the activated UL CC and the particular maximum output power of the physical channel of the activated UL CC into the same PHR and reporting the PHR to the eNB comprises:
- the UE reporting the particular maximum output power of the physical channel of all activated UL CCs;
- and wherein
- a cell where the UL CC locates comprises a primary cell and a secondary cell;
- the step of the UE reporting the particular maximum output power of the physical channel of all activated UL CCs comprises:
- the UE, for the activated UL CC in the primary cell, in a transmission mode that a physical uplink control channel (PUCCH) and a physical uplink shared channel (PUSCH) are transmitted at the same time, reporting a maximum output power of the physical channel which is used for calculating a type 1PH of the UL CC and a maximum output power of the physical channel which is used for calculating a type 2PH of the UL CC;
- in a transmission mode that the PUCCH and the PUSCH are transmitted at different times, reporting the maximum output power of the physical channel which is used for calculating the type 1PH of the UL CC;
- and
- the UE, for the activated UL CC in the secondary cell, in a transmission mode that the PUCCH and the PUSCH are transmitted at the same time or at different times, reporting the maximum output power of the physical channel which is used for calculating the type 1PH of the UL CC.
An apparatus for reporting a maximum carrier power in a carrier aggregation scenario, comprising a processor and a storage device, wherein the storage device stores processor-executable programs, and the programs comprise a processing module and a sending module, wherein,
- the processing module is configured to:
- encapsulate a particular power headroom (PH) of an activated uplink component carrier (UL CC) and a particular maximum output power of a physical channel of the activated UL CC into a same power headroom report (PHR);
- and
- the sending module is configured to:
- send out the PHR;
- wherein the processing module is configured to:
- encapsulate the particular maximum output power of the physical channel of all activated UL CCs into the PHR;
- and wherein,
- a cell where the UL CC locates comprises a primary cell and a secondary cell;
- the processing module is configured to encapsulate the particular maximum output power of the physical channel of all activated UL CCs into the PHR according to the following way:
- for the activated UL CC in the primary cell, in a transmission mode that a physical uplink control channel (PUCCH) and a physical uplink shared channel (PUSCH) are transmitted at the same time, encapsulating a maximum output power of the physical channel which is used for calculating a type 1PH of the UL CC and a maximum output power of the physical channel which is used for calculating a type 2PH of the UL CC into the PHR;
- in a transmission mode that the PUCCH and the PUSCH are transmitted at different times, encapsulating the maximum output power of the physical channel which is used for calculating the type 1PH of the UL CC into the PHR;
- and
- for the activated UL CC in the secondary cell, in a transmission mode that the PUCCH and the PUSCH are transmitted at the same time or at different times, encapsulating the maximum output power of the physical channel which is used for calculating the type 1PH of the UL CC into the PHR.
