Description
Technical field
The present embodiments relate to field of communication technology more particularly to a kind of method, terminals for triggering power headroom reporting (PHR)
And system.
Background technique
For time division duplex (the Time Division of long term evolution (Long Term Evolution, LTE)
Duplexing, TDD) system, time resource is allocated in up-downlink direction, and specifically, 7 kinds of tdd frame structural support are different
Uplink and downlink time scale distribution (being seen below shown in table 1 in detail, i.e. configuration 0-6)),
Table 1
Base station can be configured according to the characteristic of portfolio, and referring to table 1, this 7 kinds configurations include 4 kinds of 5ms periods and 3 kinds
The case where 10ms period, in the configuration in 5ms period, every 5ms includes the conversion interval of a downstream-to-upstream；And 10ms's
In period assignment, every 10ms includes the conversion interval of a downstream-to-upstream, wherein " D " indicates downlink subframe, " U " is expressed as
Row subframe, " S " are expressed as the special subframe comprising conversion interval.In the prior art, base station is according to the characteristic pair of cell business volume
Cell carries out static configuration, and still, in practical applications, the portfolio of cell can dynamically change, and LTE is being begged at present
Can be based on the service condition dynamic community adjusting TDD uplink and downlink proportional arrangement of uplink and downlink resource by base station the problem of, to make
Obtain terminal can be used the different TDD proportions enumerated in table 1 within the different periods, for example terminal is adopted in first 40ms
It is uplink and downlink proportion 0, in next 40ms using uplink and downlink proportion 2, to realize when uplink service is more system just
0 can be such as configured using the configuration of more sub-frame of uplink, can matched using downlink subframe configuration is more when downlink business is more
It sets, such as configuration 2.It can be seen that will not only can be used as uplink when the TDD of cell proportion information changes but also can make
Be called uplink and downlink flexible sub-frame for the subframe of downlink, in contrast, all can only be at any time the subframe of upstream or downstream then
For fixed subframe.Such as by system dynamic configuration, terminal can be matched in uplink and downlink and be converted between 0 and uplink and downlink proportion 2, that
3,4,8,9 work song frames are just flexible sub-frame, remaining is fixed subframe.
In LTE wireless communication system, when terminal meets preset trigger condition and certain report condition Shi Huixiang base
It stands reporting power margin, referred to as power headroom reporting (Power Headroom Report, PHR).PHR is used for terminal most
Big transmission power and the difference of the uplink power of estimation are reported to base station, to make base station according to the power headroom reported to end
End carries out power control and uplink scheduling.In the prior art, the triggering that PHR is reported mainly includes following several situations: 1, period
PHR timer is then；2, forbid reporting PHR timer then or time-out, and report rear path loss variation more than one from last PHR
Determine thresholding；3, activating upstream auxiliary carriers, etc..However for PHR is reported in the prior art trigger condition, be all terminal according to
Base station is that the PHR of the fixation subframe sent under the premise of cell static configuration TDD matches information is reported, and the information of acquisition has one
Fixed limitation, therefore be that district dynamic configures TDD and matches the application scenarios of information and needs on a kind of corresponding PHR for base station
The triggering method of report, so that base station more accurately carries out uplink scheduling.
