Specific embodiment

Following will be combined with the drawings in the embodiments of the present invention, and technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, every other embodiment obtained by those of ordinary skill in the art without making creative efforts, shall fall within the protection scope of the present invention.

It will also be understood that, in embodiments of the present invention, user equipment (User Equipment, referred to as " UE ") it is also referred to as terminal, mobile station (Mobile Station, referred to as " MS "), mobile terminal (Mobile Terminal) etc., the user equipment can be through wireless access network (Radio Access Network, referred to as " RAN ") it is communicated with one or more core nets, such as, user equipment can be mobile phone (or being " honeycomb " phone), computer etc. with mobile terminal, such as, user equipment can also be portable, pocket, hand-held, built-in computer or vehicle-mounted mobile device, they exchange language and/or data with wireless access network.

In order to facilitate understanding with the transmission method and user equipment of description upstream data provided in an embodiment of the present invention, the application scenarios of the embodiment of the present invention are introduced first below.

In embodiments of the present invention, base station can be base station (the Base Transceiver Station in GSM, referred to as " BTS "), it is also possible to the base station (NodeB, referred to as " NB ") in WCDMA, can also be evolved base station (the Evolutional Node B in LTE, referred to as " eNB or e-NodeB "), the embodiment of the present invention does not limit, but for convenience of description, and following embodiments will be illustrated by taking eNB as an example.

When UE has the demand for sending data, the license of eNB must be first obtained, i.e. UE is to the Shen eNB It please data transmission license.It should be understood that UE is sent to eNB request for data permits that there are mainly two types of modes: being that UE configuration schedules request (Scheduling Request, referred to as " SR ") resource one is eNB, UE is permitted by SR resource to the transmission of eNB request for data；Another way eNB is not UE configuration SR resource, but UE first carries out random access procedure, then carries out data transmission procedure.

After the request for data that eNB receives UE sends license, scheduling of resource decision is carried out, decides whether to provide corresponding service for the UE.The minimum unit of eNB scheduling of resource is Physical Resource Block, and Physical Resource Block is collectively formed by time-domain resource and frequency domain resource, and Physical Resource Block is the time resource of 1ms in the time domain, is the frequency resource of 12 subcarriers on frequency domain.ENB completes data dispatch on Physical Resource Block.If eNB is determined as the UE and provides service, then uplink transmission resource is distributed for the UE, then pass through Physical Downlink Control Channel (Physical Downlink Control Channel, referred to as " PDCCH ") to UE issue multi-upstream access allow (Uplink Grant, referred to as " UL grant "), the UL grant includes modulation coding scheme (Modulation and coding Scheme, referred to as " MCS "), Physical Resource Block (physical resource block, referred to as " PRB ") etc. information, the UL grant tells the UE that can transmit on which carrier wave of which time Data, and the Modulation and Coding Scheme used, so that UE accurately transmits data.

Only it is responsible for telling eNB that the UE has resource requirement it should be understood that above-mentioned UE sends license to eNB request for data, and specifically needs how many resource that can tell eNB by Signalling exchange later.Accordingly, eNB is sent according to this application data to be permitted, a small part physical resource can be first distributed for the UE, such as (Power headroom report is reported for UE reporting power margin enough, referred to as " PHR ") and/or Buffer Status Report (Buffer Status Report, referred to as " BSR ").

Then, UE reports PHR to eNB according to the physical resource and/or modulation coding scheme that indicate in UL grant, to tell the power headroom state of eNB oneself, or BSR is reported to eNB based on the physical resource and/or modulation coding scheme indicated in UL grant, to tell the remaining data volume to be transmitted of eNB oneself.

If UE has data transmission, eNB distributes suitable uplink transmission resource for the UE, then the uplink transmission resource distributed to the UE for it is informed by issuing UL grant, so as to UE reported data just using the UE PHR reported and/or BSR as reference.

Fig. 1 is shown in the art, and UE reports the basic procedure of PHR to eNB, and in this example, which is base station corresponding to authorization Spectrum Cellular.In S11, UE triggers PHR.Specifically, such as since the PHR associated timer time-out of UE or the path loss variation of the UE serving cell have been more than thresholding, to trigger PHR, UE once triggers PHR, which will be constantly in outstanding Extension state, until generating corresponding power margin information.In S12, eNB sends UL grant to UE by PDCCH, which includes the information such as MCS, PRB, it should be appreciated that in this step, the enough UE reporting power margins of physical resource indicated by the UL grant report PHR.In S13, the physical layer of UE is after being successfully received UL grant, read the information in UL grant, construction includes the Medium Access Control (MAC) Protocol Data Unit (Protocol data unit, referred to as " PDU ") of PHR, and MAC PDU is then transferred to physical layer, and cancel all triggered PHR, it should be understood that the information in UL grant is read, the specific information for reading the instruction MCS and physical resource that carry in UL grant.In S14, by physical layer physical resource according to indicated by the UL grant received in S12 and MCS, to eNB reporting MAC PDU, so that eNB can reasonably distribute uplink transmission resource next time according to the PHR that UE is reported for the UE.In S15, such as UE needs reported data, sends scheduling request SR to eNB.In S16, eNB is that UE distribution uplink transmission resource specifically determines size and the modulation coding scheme MCS etc. of physical resource according to PHR according to PHR is received in S14.In S17, eNB sends UL grant to UE by PDCCH, which includes the size for being used to indicate the physical resource in S16 for UE distribution and the instruction information of modulation coding scheme.In S18, data that UE physical resource according to indicated by UL grant received in S17 and modulation coding scheme transmit needed for reporting to eNB.

From the foregoing, it will be observed that in the art, after it includes the MAC PDU of PHR that the MAC entity of UE, which generates, just eliminating all triggered PHR.

At present, third generation partner program (3rd Generation Partnership Project, referred to as " 3GPP ") introduce authorization auxiliary access (License Assisted Access, referred to as " LAA ") cell, and LAA cell is done into carrier wave with authorization Spectrum Cellular and polymerize (Carrier Aggregation, referred to as " CA "), it should be understood that, LAA cell is done carrier wave with authorization Spectrum Cellular and is polymerize, only authorization Spectrum Cellular can be used as main plot PCell, LAA cell can only be used as supplementary cell (Secondary Cell, referred to as " SCell ").It should be understood that carrier wave polymerization is a technology in LTE/LTE-A, UE can carry out data transmission with multiple serving cells simultaneously, and the connection between any two cell may be considered preferably, i.e., propagation delay time can be ignored.In embodiments of the present invention, multiple serving cells include authorization Spectrum Cellular and LAA cell.

LAA cell with authorization Spectrum Cellular under the scene that carrier wave polymerize, the serving cell of UE has multiple, including LAA cell, then after UE triggers PHR, PHR is reported subsequently through which serving cell in multiple serving cells of the UE, UL grant has been issued at first depending on which cell in multiple serving cells, it is assumed that is that LAA cell in multiple serving cells of UE issues at first UL grant, then the UE reports PHR to eNB by LAA cell.

It should be understood that, UE is sent by LAA cell before upstream data, need first to carry out listen-before-talk (Listen before talk, referred to as " LBT ") process, LBT refers to that UE needs to carry out channel energy detection before sending upstream data, if detecting channel energy lower than some thresholding, then it is assumed that channel idle can send upstream data (also referred to as LBT success) with busy channel；Otherwise it is assumed that channel is busy, upstream data (also referred to as LBT failure) can not be sent.

In conjunction with above-mentioned Fig. 1 it is found that in current techniques, during UE reports PHR to eNB, after the completion of UE constructs the MAC PDU including PHR by MAC entity, when notifying the physical layer transmission MAC PDU, triggered PHR is just eliminated.That is, having eliminated the triggered PHR reported before sending MAC PDU.And LAA cell with authorization Spectrum Cellular under the scene that carrier wave polymerize, if UE selection sends MAC PDU by LAA cell, after physical layer receives MAC PDU, LBT process is carried out first, the transmission that PHR only just may be implemented in the successful situation of LBT cannot be to eNB reporting MAC PDU if LBT has failed, and at this point, having eliminated triggered PHR.It should be understood that the transmission of PHR is needed, there are two steps: being triggering first, secondly obtains the uplink transmission resource of carrying PHR enough.Therefore, it to send new PHR again, first has to meet until the trigger condition of the PHR of next time, and receive the UL grant for the instruction new biography that eNB is issued, just may be implemented.It is found that the serving cell in UE is LAA cell under the scene for authorizing Spectrum Cellular carrier wave to polymerize, the existing method for sending PHR reduces the reliability and timeliness for reporting PHR, so that affecting eNB is that UE distributes suitable uplink transmission resource.

In view of the above technical problems, the embodiment of the present invention proposes the transmission method and user equipment of a kind of upstream data, can effectively realize reporting in time for PHR (or BSR).

Fig. 2 shows a kind of transmission methods 100 of upstream data of offer according to embodiments of the present invention, and specifically, this method 100 is executed by user equipment (UE), and this method 100 includes:

S110 triggers power headroom reporting (PHR) PHR；

It should be understood that PHR can be constantly in the state of hang-up after UE triggers PHR, it is understood that the state sent is in for PHR, until the triggered PHR is cancelled.In other words, once triggering PHR, at this moment if UE gets UL grant, UE can send power margin information to eNB.If not triggering PHR, even if UE obtains UL grant, UE will not send power margin information to eNB.

Specifically, UE triggers PHR according to preset trigger condition, and specifically, which can be with For any one or more of the following conditions:

1) forbid PHR timer expiry, and the path loss variation when just passing data of at least one activation serving cell is more than pre-determined threshold；

2) period PHR timer expiry；

3) upper-layer configured or PHR function is reconfigured

4) any one is activated to be furnished with the SCell of uplink；

5) forbid timer expiry, and it is more than certain thresholding that at least one activation serving cell work done rate when just passing data, which retracts,.

It should be understood that it is merely illustrative and non-limiting to enumerate trigger condition above.

S120, receives the first uplink scheduling authorization UL grant of first service cell, which is unlicensed spectrum cell；

Specifically, the UL grant includes modulation coding scheme (Modulation and coding Scheme, referred to as " MCS "), Physical Resource Block (physical resource block, referred to as " PRB ") etc. information, the UL grant is for informing UE can be in which Physical Resource Block transmitting data, and the Modulation and Coding Scheme used, so that UE accurately transmits upstream data.

Optionally, the first UL grant can be sent from first service cell to the UE, can also be sent from another serving cell to the UE, such as another serving cell is the main plot of the UE, which is the secondary cell of the UE.

Specifically, which is issued by Physical Downlink Control Channel (Physical Downlink Control Channel, referred to as " PDCCH ") to UE.

It should be understood that in embodiments of the present invention, the frequency spectrum resource used that unlicensed spectrum cell refers to is the cell of unlicensed spectrum.Specifically, unlicensed spectrum cell is specifically to authorize auxiliary access (License Assisted Access, referred to as " LAA "), and at this moment the LAA cell polymerize CA as carrier wave with authorization Spectrum Cellular, and the LAA cell is secondary cell.The unlicensed spectrum cell may be cell that can independently as the serving cell of UE, and the embodiment of the present invention is not construed as limiting this.

Optionally, in embodiments of the present invention, after determination is successfully transmitted first power margin information, triggered PHR can be cancelled.

From the above, it can be seen that, transmission method provided in an embodiment of the present invention, after generating the power margin information to be reported, cancel triggered PHR at once unlike in the prior art, but retain triggered PHR (also referred to as hanging triggered PHR), the power generated is then sent to eNB Balance information determines after sending successfully, can cancel triggered PHR.Therefore, method provided in an embodiment of the present invention can guarantee the timely transmission of PHR to a certain extent, can effectively improve the transmission reliability of PHR compared with the existing technology.

It will also be understood that, in the case of the serving cell of UE includes authorization Spectrum Cellular and LAA cell, it is the equal of that authorization Spectrum Cellular and LAA cell make carrier wave polymerization CA, wherein, Spectrum Cellular is only authorized to can be used as main plot (the Primary Cell of UE, referred to as " PCell "), assuming that PCell of the authorization Spectrum Cellular as the UE in the serving cell of UE, then remaining serving cell is secondary cell (the Secondary Cell of the UE, referred to as " SCell "), it should be understood that LAA cell can only be as the SCell of the UE.It will also be understood that, PCell can pass through wireless heterogeneous networks (Radio Resource Control, referred to as " RRC ") signaling be the UE add a SCell, such as SCell of the one LAA cell of addition as the UE, the RRC signaling includes the configuration information of LAA cell, UE is by receiving the activate message (Activation MAC Control Element) that issues of PCell, so that it may use the LAA cell as SCell.

It should be understood that needing to compete uplink transmission resource before UE sends upstream data in LAA cell, specifically, by listen-before-talk LBT process competitive resource, only after successful contention to resource, data are just sent, otherwise, data can not be sent.

S141, first resource is competed by listem-before-talk LBT process, after competing first resource success, which is sent to the first service cell based on the first resource, and cancel the triggered PHR, which is the uplink transmission resource of the first UL grant instruction.

It should be understood that cancelling triggered PHR, refer to that PHR is no longer on hang-up or state to be sent, even if at this moment UE obtains UL grant, the movement for sending PHR (correspond to and send power margin information) will not be executed.

It should be understood that LBT, which refers to, carries out energy measuring to channel, energy thinks channel idle lower than certain thresholding, is higher than thresholding, and channel is occupied.At present LBT process mainly include the following types:

1) LBT without back-off, i.e. channel energy detection are lower than thresholding, continue energy measuring without retracting.

2) LBT to retract, i.e. channel energy detection are lower than thresholding, and a value x is randomly generated, after the number of Channel Detection free time is kept to 0, restarts channel energy detection.

3) channel energy detection to retract in fixed window, i.e. channel energy detection are lower than thresholding, The channel energy detection for doing to retract in one time window.

4) the rollback LBT of variable window, i.e. channel energy detection are lower than thresholding, the channel energy detection for doing to retract in a Variable Time Window.

It should be understood that physical layer is also possible to competitive resource failure before transmitting data, i.e., LBT procedure failure does not send the first power margin information in this case, and does not cancel triggered PHR, that is, continues to retain triggered PHR.

Optionally, in embodiments of the present invention, this method 100 further include:

S150 does not send first power margin information to the first service cell, and continue to retain the triggered PHR after competing first resource failure.

It having been mentioned above, UE realization reports PHR, need to meet two conditions, first is that triggering PHR, second is that receiving the UL grant that eNB is issued.It should be understood that, in the embodiment of S150 description, resource is arrived without competition in this transmission process, the first power margin information of generation can not be successfully transmitted, but due to remaining triggered PHR, so that after next time receives the UL grant that eNB is issued, so that it may it executes report PHR again, retriggered PHR when without waiting the trigger condition of PHR next time to meet.

Optionally, in embodiments of the present invention, in the case where competing first resource failure, i.e., in the case where not sending first power margin information and continuing to retain triggered PHR, this method 100 further include:

S160 receives the 2nd UL grant of second service cell；

S170 generates the second power margin information according to the 2nd UL grant and the triggered PHR, and continues to retain the triggered PHR；

S180 sends second power margin information to the second service cell according to the 2nd UL grant, wherein the second service cell is unlicensed spectrum cell or authorization Spectrum Cellular.

Specifically, as shown in figure 3, in S21, UE triggers PHR；In S22, UE receives the first UL grant that LAA cell issues；In S23, the first MAC PDU including PHR is generated by MAC entity, and retain triggered PHR；In S24, LBT process is carried out, if the success of LBT process, i.e. resource is arrived in competition, then sends the first MAC PDU to LAA cell, and cancel triggered PHR (being not shown in Fig. 3), if LBT procedure failure, the first MAC PDU is not sent, and retain triggered PHR；It in S25, determines the LBT procedure failure in S24, i.e., arrives resource without competition, no normal direction LAA cell sends first power margin information, does not cancel triggered PHR, that is, retains the triggering state of LBT；In 26, UE receives again The 2nd UL grant that two serving cells (in Fig. 3 to authorize Spectrum Cellular be to exemplify) are sent；In S27, the 2nd MAC PDU including PHR is generated by MAC entity, and retain triggered PHR；In S28, the 2nd MAC PDU is sent to second service cell by physical layer, the second service cell may be LAA cell, it could also be possible that authorization Spectrum Cellular, if the second service cell is LAA cell, step S24 is returned to, if the second service cell is authorization Spectrum Cellular, then according to existing process, the second service cell is sent by physical layer by the 2nd MAC PDU of generation.

It should be understood that in embodiments of the present invention, second service cell and first service cell can be the same serving cell, or different serving cells, the embodiment of the present invention are not construed as limiting this.

Known to above-mentioned, in embodiments of the present invention, under the scene that the serving cell of UE includes LAA cell, UE triggers PHR, and receive the UL grant of LAA cell, the first power margin information is generated, when notifying physical layer to send first power margin information to LAA cell, does not cancel triggered PHR.Physical layer competes uplink transmission resource before sending the first power margin information, when competition is to resource and is successfully transmitted the first power margin information, just cancels triggered PHR, otherwise continues to retain triggered PHR.Fail sending, in the case where retaining triggered PHR, when receiving UL grant again, reporting for PHR can be executed again, trigger condition without needing to again wait for PHR as in traditional technology meets, and receives and can just report PHR after UL grant.

Therefore, in embodiments of the present invention, in the case where determination is successfully transmitted PHR, triggered PHR is not cancelled, it maintains to retain triggered PHR, until sending successfully, just cancels triggered PHR, can effectively ensure that the transmission reliability and timeliness of PHR compared with the existing technology.

It is that UE distributes UL grant by eNB, the UE for only receiving UL grant could send upstream data, if not receiving ascending resource, UE cannot send data for upstream data it should be understood that sending data by the way of shared channel in LTE system.For receiving the UE of the UL grant of eNB transmission, it is necessary to according to the data volume that eNB is indicated, send the data packet of corresponding size.In general, a UE there may be multiple business to transmit simultaneously, accordingly there are multiple logic channels.ENB is to be shared by multiple logic channels to the ascending resource that UE is distributed, so the upstream data packet that UE is sent typically includes the data from multiple logic channels.But when eNB distribution UL grant, ascending resource accurately can't be assigned to each logic channel and gone, in general, needing voluntarily to determine which logical channel transmission how many data, this process are known as priority of logical channels after UE obtains UL grant from eNB (Logical channel prioritization, referred to as " LCP ").

UE need to consider the priority of Different Logic channel, according to the precedence information when carrying out LCP processing, for the different corresponding uplink transmission resources of logical channel assignment, in general, also needing to consider that following several priority orders for generating MAC PDU are successively as follows before carrying out LCP processing:

1) UL-CCCH data or the MAC control element including C-RNTI；

2) BSR MAC control element, but not including that padding BSR；

3) PHR MAC control element (including extended PHR and Dual Connectivity PHR)；

4) logical channel data, but in addition to UL-CCCH data；

5)Padding BSR。

In embodiments of the present invention, if a preceding PHR sends failure, so in the UL grant for receiving serving cell next time, by adjusting the LCP priority of (corresponding to " 3) PHR MAC control element " above) PHR, such as PHR is improved in above-mentioned 5 kinds of priority, to guarantee the transmission reliability of PHR.If a preceding PHR is sent successfully, PHR is triggered again in certain time thresholding, while receiving the UL grant of serving cell again, the priority of PHR can be reduced.

Optionally, in embodiments of the present invention, S170 generates the second power margin information, comprising:

S171 generates second power margin information by improving the priority of the triggered PHR.

Specifically, by improving PHR in the priority orders 1 of generation MAC PDU described above) to the priority in 5), generate include second power margin information MAC PDU.

Specifically, as shown in figure 4, in S31, UE triggers PHR；In S32, UE receives the first UL grant that LAA cell issues；In S33, the first MAC PDU including PHR is generated by MAC entity, and retain triggered PHR；In S34, LBT process is carried out, if the success of LBT process, i.e. resource is arrived in competition, then sends the first MAC PDU to LAA cell, and cancel triggered PHR (being not shown in Fig. 4), if LBT procedure failure, the first MAC PDU is not sent, and retain triggered PHR；It in S35, determines the LBT procedure failure in S34, i.e., arrives resource without competition, no normal direction LAA cell sends first power margin information, does not cancel triggered PHR, that is, retains the triggering state of LBT；In S36, UE receives the 2nd UL grant of authorization Spectrum Cellular；In S37, the LCP priority of PHR is turned up, preferentially gives PHR allocation of transmission resources；In S38, the 2nd MAC PDU including PHR is generated by MAC entity, Notice physical layer sends the 2nd MAC PDU, and retains triggered PHR；In S39, the 2nd MAC PDU is sent to authorization Spectrum Cellular by physical layer.

It should be understood that preferentially giving PHR allocation of transmission resources by the LCP priority of the height-regulating PHR in S37, can be improved the timeliness of transmission PHR.

Optionally, in S38, after generating the 2nd MAC PDU, triggered PHR can be cancelled, it should be appreciated that UE transmits data by authorization Spectrum Cellular, without competitive resource, therefore, when MAC entity generates the MAC PDU including PHR, and the MAC PDU is sent by physical layer, success can be usually sent, therefore, in such a scenario, after generating MAC PDU, when cancel triggered PHR, the embodiment of the present invention is not construed as limiting this.

Therefore, in embodiments of the present invention, PHR sends failure in a current transmission process, after receiving the UL grant of serving cell next time, by adjusting the LCP priority of PHR, so as to improve the transmission reliability of PHR.

In traditional technology, when main plot PCell is that UE adds a secondary cell SCell by RRC signaling, for example, LAA cell, when UE will use the LAA cell, Pcell can send an activate message (Activation MAC Control Element) to UE, after UE receives the activate message, LAA cell can be used, wherein, after UE receives the activate message, can trigger a PHR (corresponding to be outlined above triggering PHR trigger condition in refer to " 4) activate any one be furnished with uplink SCell ").

In embodiments of the present invention, in order to reduce a possibility that UE sends PHR by LAA cell, when activating LAA cell for UE, PHR is not triggered.

Optionally, in embodiments of the present invention, S110 triggers power headroom reporting (PHR) PHR, comprising:

Specifically, as shown in figure 5, in S41, main plot (authorization Spectrum Cellular) configures a secondary cell LAA cell to UE according to service conditions and cell conditions, specifically, main plot is that UE adds a LAA cell by RRC signaling, includes the configuration information of LAA cell in RRC signaling.In S42, authorization Spectrum Cellular sends activate message (Activation MAC Control Element) to UE；In S43, after UE receives the Activation MAC Control Element, using LAA cell, but PHR is not triggered.

It should be understood that, if LAA cell issues UL grant to UE by PDCCH, unless there are also other conditions to trigger PHR, otherwise UE would not report PHR to LAA cell after S43.

Therefore, in embodiments of the present invention, the main plot of UE is when activating LAA cell, do not trigger PHR, the probability that UE passes through LAA cell transmission PHR can be reduced to a certain extent, transmit the probability of PHR so as to increase UE by authorization Spectrum Cellular, and then can be improved the transmission reliability of PHR.

It should be understood that, UE is by the power headroom pH value for all serving cells (cell of uplink activation) that the PHR that MAC entity generates includes UE, and wherein pH value refers to the maximum carrier wave transmission power of UE and do not consider the difference of the calculated transmission power of carrier power upper limit institute.Do not consider the carrier power upper limit calculated transmission power can be understood as the calculated carrier wave transmission power of MCS, resource block size institute that UE distributed according to eNB.Carrier wave transmission power can be the transmission power of transmission PUCCH data, is also possible to transmit the transmission power of PUSCH data, can also be the transmission power of the simultaneous transmission data on PUCCH and PUSCH.PH may be negative value, i.e. UE does not consider that the calculated transmission power of carrier power upper limit institute is greater than the practical maximum carrier wave transmission power of itself, and under this situation, the data of UE will be difficult to send success, then influence data dispatch.

The PH of one cell refers to the cell in the power headroom of the data sending instant of PUSCH or PUCCH, wherein data sending instant is commonly referred to as the 4th frame at the time of UE receives UL grant after the frame of place, as shown in Figure 6.This pH value is calculated in advance before data sending instant, the specific abilities for depending on UE how many in advance, as shown in Figure 6, UE receives the UL grant from eNB in subframe 1, new data transmission is carried out in subframe 5, the MAC PDU that construction includes PHR MAC Control Element is carried out in subframe 2,3, the MAC entity of 4, UE.Wherein, the pH value reported in PHR MAC Control Element is power headroom of the UE in subframe 5.For any one cell, UE sends if there is PUSCH data, will report a true type 1PH value, otherwise, report a virtual type 1PH value.It should be understood that the type 1PH of a cell refers to the power headroom for being the cell in the data sending instant of PUSCH or PUCCH.If UE is configured with simultaneous transmission PUSCH and PUCCH, type 1PH of the UE in addition to reporting all serving cells equipped with uplink will also report the type 2PH of main plot.If there is PUCCH data is transmitted, then UE just reports a true type 2PH, if transmitted without PUCCH data, UE just reports a virtual type 2PH, it should be understood that the type 2PH of main plot refers to the main plot in the power headroom of the data sending instant of PUCCH and PUSCH.

But for LAA cell, if the LBT procedure failure of LAA cell, can not just transmit data.Even if UE has data to transmit in LAA cell, but during actual transmissions when progress LBT, possible competitive resource failure leads to that data can not be transmitted in practice.Therefore, according in the prior art Determined according to the data transfer demands of UE the pH value of LAA cell be it is unreasonable, may cause pH value and be not consistent with real process, and then the problems such as the uplink transmission resource for being likely to result in the lower sub-distribution of eNB is too small.

In view of the above-mentioned problems, in embodiments of the present invention, when generating PHR, the pH value of LAA cell is all pressed virtual value filling.

Optionally, in embodiments of the present invention, this method 100 is executed by user equipment (UE), the serving cell of the UE includes authorization Spectrum Cellular and unlicensed spectrum cell, the serving cell are the cell equipped with uplink activated, wherein, S140 generates the first power margin information, comprising:

Specifically, Fig. 7 show include M+N cell pH value PHR schematic diagram, wherein, M authorization Spectrum Cellular, N number of LAA cell, UE are configured with the function of simultaneous transmission PUSCH and PUCCH, and the c1 to c7 in the first row is that serving cell indexes (cell Index), P is used to indicate whether progress back-off, and it is true or virtual that V, which is used to indicate pH value,；R indicates reserved bit；Second row to fifth line indicates that the PH of main plot is reported, wherein the second row and the third line indicate that the type 2PH of main plot is reported, wherein, PH (Type 2 in second row, main plot) indicate be UE main plot type 2PH value, wherein Type2 is the calculated pH value of resource institute that UE is distributed according to PUSCH and PUCCH in the case where configuring PUSCH and PUCCH transmission simultaneously.P in the third line_cmax,cRefer to maximum carrier wave transmission power of the main plot in the case where being configured with simultaneous transmission PUSCH and PUCCH.Fourth line and fifth line indicate that the type 1PH of main plot is reported.As shown in figure 5, in embodiments of the present invention, for LAA cell, the 10th row to 13 rows in corresponding diagram 5, UE no matter under no PUSCH data cases or in the case where having PUSCH data to report, filled always with virtual value by the type 1PH value of the LAA cell.For the authorization Spectrum Cellular as supplementary cell, according further to whether having PUSCH transmission, type 1PH value is determined, if there is PUSCH transmission, then reporting a true type 1PH；If reporting a virtual type 1PH without PUSCH transmission.

It should be understood that it is one such representation that PHR involved in the embodiment of the present invention, which reports format, the mode of being not done is limited, including final content.

It should be understood that pH value involved in the embodiment of the present invention is virtual value, which refers to that pH value is in the case where no PUSCH transmission, according to the pH value of the calculating of parameter format as defined in agreement.

Therefore, in embodiments of the present invention, for authorizing Spectrum Cellular, in PHR MAC Control The pH value reported in Element is that really, for being furnished with the activation LAA cell of uplink, the pH value reported in PHR MAC Control Element is filled by virtual value, and the uplink transmission resource that eNB can be avoided to distribute to a certain extent is improper.

It should be understood that the authorization Spectrum Cellular in the embodiment of the present invention is also referred to as Normal cell.
