Description

Method, device and system for processing power headroom report

Processing method and processing device, the system of power headroom reporting (PHR)

Technical field

The present embodiments relate to communication technical field, more particularly to a kind of processing method and processing device of power headroom reporting (PHR), system.Background technology

Senior long term evolution（Long Term Evolution-Advanced, LTE-A) be 3GPP LTE systems Jin mono- Walk evolution systems.In LTE-A (Release 10) system, carrier aggregation is introduced for the peak data rate requirement of the forth generation communication technology to meet International Telecommunication Union（Carrier Aggregation, CA) technology.In carrier aggregation, two or more member carriers（Component Carrier) frequency spectrum be grouped together in together to obtain broader transmission bandwidth, the frequency spectrum of each member carrier can be adjacent continuous frequency spectrum, can also be non-conterminous frequency spectrum even different frequency bands in identical frequency band in discontinuous spectrum.LTE-A user equipmenies（User Equipment, UE) transmitting or reception of data can be carried out using multiple member carriers according to its ability and business demand simultaneously.

CA systems compatible existing LTE-A are that the carrier wave under same base station (eNodeB, eNB) is polymerize, or have preferable passback (Backhaul;) macrocell and Microcell under carrier aggregation, such as macrocell and Microcell are connected by optical fiber（Now Microcell can also be less radio-frequency head）, the information base carried on so multiple carrier waves can be obtained in time, and base station can in combination be dispatched to multiple carrier waves, and in CA systems multiple cells downlink Shi Tong Walk, error is less than 260ns.

In CA systems compatible existing LTE-A, UE can launch multiple up channels simultaneously in multiple cells, and each cell uses different carrier waves.Wherein, each cell has the uplink transmission power upper limit of oneself, even if the channel emission power of each cell is no more than the upper limit of the power of each cell, total transmission power of multiple channels still is possible to the maximum transmission power configured more than UE.In order that eNB knows UE power service condition, so as to aid in eNB to determine the uplink scheduling to UE, UE needs reporting power margin to report（Power headroom report, PHR eNB) is given, wherein, PHR is used to the difference of UE maximum transmission power and UE uplink channel transmission power reporting eNB, uplink scheduling is carried out to UE for eNB important reference is provided, the PHR that eNB can be reported according to UE, obtains UE dump power information, so as to be determined as the Radio Resource of UE scheduling.PHR is that UE is respectively calculated and reported for each cell, That is UE calculate its a sub-frame of uplink of a cell maximum transmission power and UE the cell the sub-frame of uplink uplink channel transmission power difference, and report eNB.

In existing CA systems, due to towards different reception place/cells, launch time of the up channel that UE launches simultaneously can not be perfectly aligned, and UE can have multiple timing advance groups（Timmg Advance Group, TAG), generally, 4 TAG are could support up in CA systems.Wherein, TAG is a small district's groups, and the timing of the UE of the cell in this group up channel is identical.If the cell of two channels of transmitting belongs to same TAG, the Timing Advance of the up transmitting of the two channels is one, and the time timing of the up transmitting of the two channels is identical.Belonging to different TAG cell has different Timing Advances, and its up channel may have different uplink transmission times.In existing CA systems, for any two TAG, the launch time difference of its up channel is that within 1 symbol, according to 3GPP RAN4 protocol requirements, more accurately, the launch time difference of its up channel is less than or equal to 32.47us.

The schematic diagram that partly overlaps of the launch time of up channel when Fig. 1 belongs to different TAG for up channel in existing CA systems a, as shown in figure 1, subframe（Subfmme it is) by multiple single-carrier frequency division multiple access (Single Carrier Frequency Division Multiple Access, SC-FDMA) symbol is constituted, shown in dotted line is last SC-FDMA symbol of the subframe i of the cell in TAG1 up channel, and first SC-FDMA of the subframe j+1 of this symbol and the cell in TAG2 up channel, which exists, to partly overlap.Wherein, 1=0,1,2 ..., 9, it is subframe number, subframe 1+1 refers to next subframe of subframe 1.As ι+1>When 9, indicate (i+l) modl0 as the subframe of numbering.

In existing CA systems, due to not over one SC-FDMA symbol of timing difference of the launch time of the up channel of different TAG cell, as shown in figure 1, subframe i and subframe j+1 overlapping time are smaller, not over one SC-FDMA symbol.When UE in subframe i triggers reporting for PHR, UE can calculate the subframe j of the subframe i of TAG1 cells PHR and TAG2 cells PHR, and report base station, and the subframe j+1 of TAG2 cells PHR need not be calculated and reported.Now, it is due to not over one SC-FDMA symbol of timing difference between them, when calculating and reporting PHR although subframe 1 and j not exclusively align, it is that the time is upper " identical subframe " to think subframe i and j, therefore does not interfere with uplink schedulings of the eNB to UE.

However, in the lte-a system of follow-up evolution, introducing the carrier aggregation between base station, that is, dual link（Dual Connectivity, DC), now UE and two base station connection, carries out the transmitting and reception of data.Being between base station now can not the information such as real-time, interactive schedule information between non-ideal passback, base station.Two base stations are master base station（Master eNB, MeNB) and from base station（Secondary eNB, SeNB ).One or more carrier wave/cells can be included in master base station or slave base station.Carrier wave set/small district's groups in master base station are referred to as main plot group（Master Cell Group, MCG), and it is referred to as secondary cell group from the carrier wave set in base station/small district's groups（Secondary Cell Group, SCG) .In DC systems, each eNB/CG can at most support 4 TAG, also just say that two eNB at most may have 8 TAG situation.Each TAG includes one or more cell with identical up timing.In DC systems, two base stations should not Seeking Truth Tong Walk, that is there is the arbitrary time difference in the downlink subframe initial time of two base stations, and then under this non-same Walk DC scene, multiple sub-frame of uplink that UE is sent to two base stations will the overlapped situation of time of occurrence, and time-interleaving part is no longer as in CA systems only no more than the overlapping region of 1 SC-FDMA symbol duration, it may be possible to any duration.

The schematic diagram that partly overlaps of the launch time of up channel when Fig. 2 belongs to different TAG for up channel in existing DC systems, as shown in Figure 2, TAG1 cell and TAG2 cell belong to different base station/cell groups, the timing of the He of subframe 1 " there may exist larger gap; therefore, and subframe 1 and subframe j+ Ι overlapping time are possible to than larger.

In the prior art under Yi Walk DC scenes, UE triggers when reporting eNodeBl of PHR in the subframe i of TAG1 cells, for the PHR of another eNodeB2 sub-frame of uplink, and UE needs to calculate simultaneously and report the PHR for having first overlapping subframe with subframe i to eNodeB2.As shown in Fig. 2, UE needs to report subframe j PHR to eNodeB2, and no matter subframe j+1 and subframe i overlapping time has much.

However, the subframe for the PHR for determining to calculate and reporting due to not accounting for the overlapping time of subframe 1 and subframe J+1.When subframe j+1 and subframe i overlapping time is very big, subframe i and subframe j PHR that UE is calculated and reported, power service conditions of the UE in two Ge Yi Walk eNodeB up transmitting can not be reflected, therefore, eNodeB can not be calculated according to UE and the subframe i and subframe j PHR that report judge power service conditions of the UE in two eNodeB up transmitting, so as to influence eNodeB to the accuracy of UE uplink scheduling.The content of the invention is the present invention provide a kind of processing method and processing device of power headroom reporting (PHR), system, power service condition of the user equipment in the up transmitting of two base stations can be accurately reflected, so that base station correctly judges power service condition of the user equipment in the up transmitting of two base stations, accuracy of the base station to the uplink scheduling of user equipment is improved.
