Description
Technical field
The present invention relates to the senior Long Term Evolution of GSM, relate in particular to the method and the device of the specific maximum power of reporting subdistrict under the carrier aggregation scene.
Background technology
Long Term Evolution (long term evolution; Be called for short LTE) be a kind of advanced person's of third generation partner program (The 3rdGeneration Partnership Project is called for short 3GPP) exploitation wireless access wide band technology, can support the single carrier bandwidth of the highest 20M; Reach the upstream rate of 50M bps and the downstream rate of 100Mbps; And having low time delay, possessed the characteristic of the 4th third-generation mobile communication, is the technology of a kind of ultra 3G (Beyond 3G).
On the LTE standard, 3GPP has developed senior Long Term Evolution (long term evolutionadvanced is called for short LTE-A); Developed carrier aggregation; The multiple-input and multiple-output of high-order (MultipleInput Multiple Output, be called for short MIMO) more, relaying; Multi-point cooperative is handled a series of technology such as (comp); With the demand of the 4th third-generation mobile communication system of senior international mobile communication (IMT-ADVANCED) definition of satisfying radio communication department of International Telecommunications Union (ITU-R), such as the upstream rate of 500bps, the downstream rate of 1Gbps.
Carrier aggregation (CA) is to collect to support higher throughput (throughput) through the frequency range that will be positioned at same frequency band (band) or different band; Under the REL-10 of carrier aggregation version; Different carrier waves all is the REL-8/REL-9 of compatible LTE, promptly is the sub-district with complete function.The sub-district at one of them carrier wave place is called main plot (Pcell), other be called from the sub-district (Scell).Pcell is different from Scell, and Pcell is responsible for setting up Radio Resource control (RRC) and connects, and is responsible for security parameter; The renewal of system information is responsible in the reception of duty pager message, is responsible for the carrier wave of other sub-districts of scheduling; Be responsible for the transmission of up feedback, or the like special function; The function of Scell is comparatively single, can regard that auxiliary Pcell accomplishes the band resource of communication task as, but certain independence is also arranged, and comprises independent receiving scheduling signaling, independently carries out power control etc.
Because the particularity of Pcell is under Radio Resource control-connected state (RRC-connected) state at UE, Pcell will be (activated) that activates forever; Promptly no matter UE and eNB can both use it timely, and Scell are as assisted cell; In some time period; There is not up-downgoing transmission to take place, in these time periods, Scell is in nonactivated (deactivated) state.Because the running time-frequency resource that LTE/LTE-AUE uses all is the eNB scheduling, so the information that eNB need obtain UE carries out correct uplink time scheduling, simultaneously; ENB also needs the information of UE to carry out correct uplink power control, makes UE reach destination service quality (QoS), and reduces the problem of disturbing between the co-frequency cell of LTE/LTE-A to a certain extent; The information of UE comprises uplink detection signal (sounding reference signal is called for short SRS), and PHR constant power balance information etc.; The former reflects the channel quality of up-link carrier; The latter is reflected the power headroom of up-link carrier, and eNB can come the time-frequency piece position of selection scheduling according to channel quality, can be according to power headroom; Come the time-frequency number of blocks of selection scheduling, select modulation format etc.
In the REL-8/REL-9 standard, subscriber equipment has triggered power headroom reporting PHR, and satisfied transmission condition, and UE need send PHR MAC CE so, and the transmission flow of PHR MAC CE is as shown in Figure 1.In the REL-10 standard, if Scell is under the deactivated state, UE need not report PHR for this Scell.Therefore, the trigger event of subscriber equipment comprises trigger event and the activate incident of REL-8/REL-9, if promptly UE is when cycle PHR timer expires; If perhaps the component carrier path loss changes greatly; Perhaps trigger PHR during the PHR configuration/reconfiguration and report, and this Scell is when being activated, PHR will be triggered; After UE has obtained enough ascending resources, PHR will be sent out.
Because carrier aggregation, and each Scell uses independently power control process, and each Scell is with reporting PH respectively, and the UE of carrier aggregation will adopt new PHR form; The ULPCC of the UE of carrier aggregation is for Physical Uplink Control Channel (physical uplink control channel; Be called for short PUCCH) and Physical Uplink Shared Channel (Physical uplink shared channel; Abbreviation PUSCH) transmission has two kinds of possible patterns: (1) mode pattern 1:PUCCH and PUSCH timesharing are sent, and be identical with REL-8/REL-9.(2) mode pattern 2:PUCCH and PUSCH send simultaneously.
For pattern 1, when PHR sent, no matter UL PCC and UL SCC only need report Type1PHR.Type1 PHR is defined as the transmitted power that the gross power of UL PCC is removed the PUSCH channel, such as:
Type1 PHR:PH1=P
Cmaxc-P
PuschFormula (formula) 1
For pattern 2, when PHR sends, for UL SCC, only need to send Type1 PHR; For UL PCC, UE need report Type1 PHR and Type2 PHR.Type2 PHR is defined as the gross power of UL PCC and removes the transmitted power of PUSCH channel and the transmitted power of PUCCH channel, such as:
Type2PHR：PH2＝P
cmaxc-P
pucch-P
pusch formula2
Wherein, P
CmaxcBe the peak power output of UL PCC, P

When PHR sent, the Scell of activation did not have up transmission, and UE will send virtual PHR for this Scell so, and this virual PHR uses the PUSCH form of reference format.There is not up transmission if Pcell is last; UE will send virtual type1 PHR for Pcell so, and promptly this type1 PHR uses the PUSCH form of reference format, if there is not PUCCH on the Pcell; Need send virutal type2 PHR so; This type2 PHR will use the PUCCH form of reference format, and these two kinds have all had definition with reference to form, can be with reference to 3GPP 36.321 series standards.
