Description
Report the method and device of the power headroom of subscriber terminal equipment
Technical field
The present invention relates to power headroom reporting (PHR), more particularly to using carrier aggregation technology communication network in report subscriber terminal equipment power headroom method and device.Background technology
The power headroom of up-link（PH, power headroom) just blunt announcement the Power related information of subscriber terminal equipment can be supplied to base station, to assist base station to carry out scheduling of resource.In LTE (Long Term Evolution) system, the information included by the blunt announcement of power headroom 4 is the difference between the nominal maximum transmit power of subscriber terminal equipment and the estimation transmit power of Uplink Shared Channel.
Figure la and figure lb are the MAC PDU sub-headers (Media Access Control Protocol Data Unit subheader) and power headroom MAC Control Element of reporting power margin in LTE system respectively（Element schematic diagram).The length for scheming the sub-header shown in la is 1 byte.R is reserved field（), field it is set to " 0 "；E is extended field, for indicating whether there are more fields in MAC header；LCID is logic channel identification code（Logical Channel ID) field, the MAC load follow-up for identifying（Payload logic channel entity), the LCID of 5 bits is to that should have 32 indexes, a portion index（01011 to 11001) it is reserved index, i.e., is also not used.The length for scheming the power headroom MAC Control Element shown in lb is 1 byte.R is reserved field, is set to " 0 "；PH is the power headroom field of 6 bits, for indicated horsepower surplus.In LTE, when reporting power headroom, the sub-header that a sub-header corresponds in a power headroom MAC Control Element, i.e. figure la identifies the power headroom MAC Control Element in figure lb by LCID fields.The content of the invention
Inventor have recognized that, introducing the LTE-A of carrier aggregation
(LTE-Advanced) in system, power headroom reporting (PHR) mechanism can not meet multiple component carriers used in LTE（Component carrier) demand.In the system for being introduced into the LTE-A of carrier aggregation, base station and subscriber terminal equipment can support the data transfer on multiple component carriers.Due to the channel conditions corresponding to each component carrier can different and each component carrier independently carry out Power Control, power She amount of each component carrier may be different, therefore a subscriber terminal equipment needs to report the power margin information of each component carrier to base station.On multiple component carriers power margin information can respectively on respective component carrier transmission, only transmission or transmitted using other modes on one-component carrier wave.If in addition, one-component carrier wave is set in multiple component carriers to be needed the channel power surplus of the data channel of main carrier and control channel as main carrier, also respectively to base station repeats.Existing power headroom reporting (PHR) mechanism can not meet above-mentioned multiple demands, i.e., can not realize the report of the power headroom of multiple component carriers.

One according to the first aspect of the invention is used to reporting power headroom relevant information into the method to a network equipment embodiment there is provided a kind of in a subscriber terminal equipment.Subscriber terminal equipment can be realized in several ways, such as mobile phone or notebook computer.The network equipment can be realized in several ways, such as base station or relay station.
The transmission channel of the subscriber terminal equipment is provided with multiple component carriers, and power headroom relevant information indicates at least one component carrier of the subscriber terminal equipment in multiple component carriers
Channel power surplus.The transmission channel of subscriber terminal equipment is that subscriber terminal equipment is used to send control information and data message to the channel of the network equipment.
Channel power surplus can be the power headroom corresponding to a variety of channels, and such as subscriber terminal equipment corresponds to the data channel of one-component carrier wave（Such as PUSCH, Physical Uplink Shared Channel, Physical Uplink Shared Channel）Power headroom or the control channel corresponding to one-component carrier wave（Such as PUCCH, Physical Uplink Control Channel, Physical Uplink Control Channel）Power headroom.Channel power surplus can be obtained in several ways.For example, channel power surplus is the difference between the nominal maximum transmission power of subscriber terminal equipment and PUSCH estimation transmit power.And for example, channel power surplus is the difference between the nominal maximum transmission power of subscriber terminal equipment and PUCCH estimation transmit power.For another example, channel power surplus is the difference between the nominal maximum transmission power of subscriber terminal equipment and PUSCH and PUCCH total estimation transmit power.
Reference picture 2, the method comprising the steps of 210, and subscriber terminal equipment obtains power headroom relevant information.Power headroom relevant information can be represented with various ways, such as the PH fields of 6 bits in LTE.Table 1 is can refer to, the power headroom grade according to belonging to channel power surplus, to determine the PH fields of power headroom relevant information, i.e. 6 bits.Power headroom such as one-component carrier wave belongs to power headroom registration POWER_HEADROOM -3, then PH fields are 3 tables 1
This method also includes Bu Sudden 220, and subscriber terminal equipment determines a header and at least one power headroom control unit according to power headroom relevant information.The control of at least one power headroom is single
Member includes power headroom relevant information.Header includes the information of at least one bit, and the information of at least one bit is used for first transmission form of the indicated horsepower surplus relevant information at least one power headroom control unit；And/or at least one power headroom control unit includes the information of at least one bit, the information of at least one bit is used for second transmission form of the indicated horsepower surplus relevant information at least one power headroom control unit.
First sends the transmission form that form is power headroom relevant information.For example, first sends the channel type corresponding to channel power surplus of the form including at least one component carrier, the power headroom of such as data channel or the power headroom of control channel.And for example, the first transmission form includes the bit length of at least one power headroom control unit, and such as power headroom control unit, which has altogether, occupies 42 bits.For another example, the first transmission form includes the carrier index of at least one component carrier：After such as the channel of each component carrier is numbered, component carrier is indexed with the mode of numbering is indicated；Or, the order and corresponding indicating bit for the channel transmission power for sending each component carrier are pre-defined, by setting the numerical value of corresponding indicating bit to index component carrier.And for example, the first transmission form includes the number of unit of at least one power headroom control unit, such as one header two power headroom control units of correspondence.
