Description
Technical field
The present invention relates to the communications field, be specifically related to power control command in a kind of carrier aggregation
Transmission method, base station and subscriber equipment.
Background technology
4G network (Long Term Evolution, be called for short: in Rel-10 LTE),
Introduce the carrier aggregation of most 5 carrier waves to support maximum 100M bandwidth, after each carrier wave is
To compatible carrier wave, only there is uplink control channel (Physical on main plot (PCell)
Uplink Control Channel, is called for short: PUCCH) transmission is used for feeding back physical down and shares
(Physical Downlink Shared Channel is called for short: confirmation letter PDSCH) channel
Breath (Acknowledgement is called for short Ack) or (Nacknowledgement, abbreviation
Nack).MeNB) and micro-introducing dual link technology in Rel-12, macro base station (is called for short:
Base station (is called for short: SeNB) may not be preferable back haul link, now macro base station main plot
(it is called for short: PCell) (be called for short: PSCell) (carrying PUCCH's with main plot, micro-base station
SCell) public search space can all be carried.In Rel-13, introduce and could support up 32 carrier waves
Carrier aggregation, secondary cell (SCell) allows also to PUCCH transmission, but do not carry
Public search space.
In Rel-10 carrier aggregation, in order to reduce subscriber equipment (User Experience, letter
Claiming: UE) carry public search space on blind Detecting number of times, only PCell, common search is empty
Between for transmit system information Downlink Control Information (be called for short: DCI), organize power control information
DCI, it is also possible to transmission uplink scheduling DCI.Rel-13 support in the polymerization of 32 carrier waves,
Public search space is not carried, it is impossible to carrying group power control commands information on PScell, but main little
District is with secondary cell path loss with reference to possible different, and this have impact on PUCCH and Uplink Shared Channel
(Physical Uplink Shared Channel, is called for short: through-put power PUSCH), special
It not that (Semi-Persistent Scheduling is called for short: SPS) business to semipermanent scheduling
Or there is no the scene that the PUSCH of dynamic authorization retransmits.The configuration figure of group power control at present
(TPC-PDCCH-Config) as it is shown in figure 1, each UE is at radio resource control
(Radio Resource Control is called for short: can be configured 1 when RRC) setting up or rebuild
Power control identifier (tpc-RNTI) and power control to index (tpc-Index), wherein,
Tpc-RNTI is used for decoding public search space DCI information, and tpc-Index mark UE is in group
Position in power control information, but this configuration information does not has the PUCCH power control of SCell
Information processed, causes UE to send PUCCH with inappropriate power, and then other is used to community
Family produces interference.

Detailed description of the invention
Below in conjunction with the accompanying drawings, the detailed description of the invention of invention is further described.Hereinafter implement
Example is only used for clearly illustrating technical scheme, and can not limit this with this
Bright protection domain.
Following example of the present invention are all based on what the Rel-13 version of LTE illustrated.
The transmission method of power control command in a kind of carrier aggregation that the embodiment of the present invention provides,
The method includes:
Main plot subscriber equipment carry out radio resource control RRC foundation or rebuild time,
Configuration information, described configuration information bag is sent to subscriber equipment by downlink control channel
Include: control described subscriber equipment and pass through uplink control channel or Uplink Shared Channel to auxiliary little
The configuration information of the power of district's transmission data, so that described subscriber equipment is according to described configuration letter
Breath, is obtained and is passed to main plot and secondary cell by uplink control channel or Uplink Shared Channel
The power of transmission of data, and transmit data according to described power to main plot or secondary cell.
Said method, is believed in this configuration when sending configuration information to subscriber equipment by main plot
Breath increases control subscriber equipment and passes through uplink control channel or Uplink Shared Channel to auxiliary
The configuration information of the power of cell data transmission, so that subscriber equipment can be known by up
Link control channel or Uplink Shared Channel transmit the power of data to main plot and secondary cell, solve
Subscriber equipment of having determined cannot obtain the problem of power to secondary cell transmission data, it is to avoid with
Family equipment, caused producing other users of community with inappropriate power when secondary cell transmits data
Raw interference.
Present invention also offers the stream of the transmission method of power control command in a kind of carrier aggregation
Journey schematic diagram, as in figure 2 it is shown, the method includes:
201, subscriber equipment is when radio resource control RRC sets up or rebuilds, and receives
The configuration information that main plot is sent by downlink control channel, described configuration information includes:
Control described subscriber equipment and pass through uplink control channel or Uplink Shared Channel to secondary cell
The configuration information of transmission data power；
202, described subscriber equipment is according to described configuration information, obtains by up-link control
Channel or Uplink Shared Channel transmit the power of data to main plot and secondary cell, and according to described
Power transmits data to main plot or secondary cell.
Said method subscriber equipment according to main plot to subscriber equipment send configuration information time,
This configuration information increases and controls subscriber equipment by uplink control channel or up shared
Channel, to the configuration information of the power of secondary cell transmission data, is known and is controlled letter by up-link
Road or Uplink Shared Channel transmit the power of data to main plot and secondary cell, solve user and set
The problem of the standby power that cannot obtain to secondary cell transmission data, it is to avoid at subscriber equipment with not
Appropriate power, when secondary cell transmission data, causes other users of community are produced interference.
In a particular application, described configuration information also includes: control described subscriber equipment by upper

Described subscriber equipment is transmitted to secondary cell by uplink control channel or Uplink Shared Channel
The instructions field of data power；
Accordingly, described instructions field is boolean type, when the value of described instructions field is true,
Described subscriber equipment controls index according to described first power and obtains by up-link control letter
Road or Uplink Shared Channel are to the power of main plot transmission data；
Described subscriber equipment obtains and controls, with described first power, the value that index is adjacent, and will be with institute
State the first power and control the adjacent value of index as by uplink control channel or up common
Enjoy the channel power to secondary cell transmission data.
As shown in Figure 4, increasing SCelltpc-index territory, this territory is a boolean type, when
When this value is true, the TPC index of original TPC-Index instruction PCell, phase after this index
The adjacent TPC that value is SCell index, the TPC position of such implicit expression instruction SCell, with the first
Scheme is compared, and this first scheme decreases signaling bit number.
Above two scheme all can enable the configuration letter that subscriber equipment sends according to main plot
Breath obtains the power to secondary cell transmission data, thus avoids at subscriber equipment with inappropriate
Power, when secondary cell transmission data, causes other users of community are produced interference.
Present invention also offers a kind of base station, this base station includes: sending module；
