Embodiment
Fig. 2 be according to an embodiment of the invention in subscriber terminal equipment for power headroom relevant information being reported to the flow chart of the method for the network equipment.
According to a first aspect of the invention one embodiment there is provided a kind of in a subscriber terminal equipment for power headroom relevant information being reported to the method for a network equipment.Subscriber terminal equipment realizes by various ways, such as mobile phone or notebook computer etc.The network equipment realizes by various ways, such as base station or relay station etc.
The transmitting channel of this subscriber terminal equipment is provided with multiple component carrier, and power headroom relevant information indicates the channel power surplus of at least one component carrier of this subscriber terminal equipment in multiple component carrier.The transmitting channel of subscriber terminal equipment be subscriber terminal equipment for send control information and data message to the channel of the network equipment.
Channel power surplus can be the power headroom corresponding to multiple channel, as subscriber terminal equipment corresponds to the data channel of one-component carrier wave (as PUSCH, Physical Uplink SharedChannel, Physical Uplink Shared Channel) power headroom or correspond to the control channel of one-component carrier wave (as PUCCH, Physical Uplink Control Channel, Physical Uplink Control Channel) power headroom.Channel power surplus is obtained by various ways.Such as, channel power surplus is the difference between the nominal maximum transmission power of subscriber terminal equipment and the estimation transmitted power of PUSCH.And for example, channel power surplus is the difference between the nominal maximum transmission power of subscriber terminal equipment and the estimation transmitted power of PUCCH.For another example, channel power surplus is the difference between the nominal maximum transmission power of subscriber terminal equipment and total estimation transmitted power of PUSCH and PUCCH.
With reference to Fig. 2, the method comprising the steps of 210, and subscriber terminal equipment obtains power headroom relevant information.Power headroom relevant information can represent with various ways, as the PH field of 6 bits in LTE.Can refer to table 1, the power headroom grade belonging to channel power surplus, determines power headroom relevant information, i.e. the PH field of 6 bits.Power headroom as one-component carrier wave belongs to power headroom registration POWER_HEADROOM_3, then PH field is 3
Table 1
The method also comprises step 220, and subscriber terminal equipment determines a header and at least one power headroom control unit according to power headroom relevant information.At least one power headroom control unit comprises power headroom relevant information.Header comprises the information of at least one bit, and the information of this at least one bit is used to indicate the first transmission form of power headroom relevant information at least one power headroom control unit; And/or at least one power headroom control unit comprises the information of at least one bit, the information of this at least one bit is used to indicate the second transmission form of power headroom relevant information at least one power headroom control unit.
First sends the transmission form that form is power headroom relevant information.Such as, the first transmission form comprises the channel type corresponding to channel power surplus of at least one component carrier, as the power headroom of data channel or the power headroom etc. of control channel.And for example, the first transmission form comprises the bit length of at least one power headroom control unit, as power headroom control unit occupies altogether 42 bits.For another example, the first transmission form comprises the carrier index of at least one component carrier: after being numbered by the channel of each component carrier, carrys out index component carrier by the mode of instruction numbering; Or the order of the channel transmission power of each component carrier of pre-defined transmission and corresponding indicating bit, carry out index component carrier by the numerical value arranging corresponding indicating bit.And for example, the first transmission form comprises the number of unit of at least one power headroom control unit, two power headroom control units as corresponding in a header.
