Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those skilled in the art obtain, all belongs to the scope of protection of the invention.
Refer to accompanying drawing 2, it is the downward special physical channel DPCH time slot format configurating method schematic flow sheet that the embodiment of the present invention provides, its executive agent can be the evolution base station (evoluted NodeB, eNB) in base station or Long Term Evolution (Long Term Evolution, LTE) system.The method of accompanying drawing 2 example mainly comprises step S201 and step S202, is described in detail as follows:
S201, base station receive radio network controller (RNC) instruction configuration, described in be configured to DPCH time slot format index.
In embodiments of the present invention, radio network controller (Radio Network Controller, RNC) is responsible for the configuration of base station instruction to DPCH time slot format, and what it indicated is configured to DPCH time slot format index, be indicated to base station by signaling or protocol frame, base station receives the configuration of RNC instruction.
S202, DPCH time slot format is determined according to time slot format mapping table and described DPCH time slot format index in base station, described time slot format mapping table comprises time slot format index and time slot format mapping relations, and in described DPCH time slot format, each time slot comprises transmission power control instruction TPC territory.
The territory that in DPCH time slot format, each time slot comprises, as shown in accompanying drawing 1-a, specifically comprises data 1(Data1) territory, transmitting power control (TPC) territory, transformat merges instruction (TFCI) territory, data 2(Data2) territory and pilot tone (Pilot) territory.In embodiments of the present invention, side, base station remains with time slot format mapping table as shown in table 1 below:
Table 1
Time slot format is associated with the spreading factor of descending DPCH (Spread Factor, SF), the corresponding set of time-slot form of each spreading factor.The time slot format mapping table of table 1 example comprises following column and DPCH time slot format index (Slot Format#i), channel bit rate (Channel Bit Rate, CBR), channel symbol rate (Channel Symbol Rate, CSR) bit number (DPCCH Bits/Slot) etc. that in the bit number (DPDCH Bits/Slot) that, in spreading factor (Spread Factor, SF), each time slot, DPDCH takies and each time slot, DPCCH takies.
As long as base station receives the DPCH time slot format index that RNC issues, then can determine DPCH time slot format according to time slot format mapping table and time slot format index.Such as, if the DPCH time slot format index that RNC issues is 17#, due to data 2(Data2) bit number (N that takies of territory data2) be 8 bits, transmitting power controls the bit number (N that (TPC) territory takies tPC) be 2 bits, its co-domain does not all take bit, then according to the descending DPCH structure of accompanying drawing 1-a example, base station, according to the time slot format index of table 1 example and time slot format mapping relations, determines that DPCH time slot format is as shown in accompanying drawing 3-a.For another example, if the DPCH time slot format index that RNC issues is 18#, due to data 1(Data1) bit number (N that takies of territory data1) be 2 bits, data 2(Data2) bit number (N that takies of territory data2) be 6 bits, transmitting power controls the bit number (N that (TPC) territory takies tPC) be 2 bits, its co-domain does not all take bit, then according to the descending DPCH structure of accompanying drawing 1-a example, base station, according to the time slot format index of table 1 example and time slot format mapping relations, determines that DPCH time slot format is as shown in accompanying drawing 3-b.Also as, if the DPCH time slot format index that RNC issues is 19#, due to data 1(Data1) bit number (N that takies of territory data1) be 4 bits, data 2(Data2) bit number (N that takies of territory data2) be 2 bits, the bit number (NTPC) that transmitting power control (TPC) territory takies is 2 bits, and transformat merges the bit number (N that instruction (TFCI) takies tFCI) be 2bit, its co-domain does not all take bit, then according to the descending DPCH structure of accompanying drawing 1-a example, base station, according to the time slot format index of table 1 example and time slot format mapping relations, determines that DPCH time slot format is as shown in accompanying drawing 3-c.The DPCH time slot format contrasting above-mentioned accompanying drawing 3-a to accompanying drawing 3-c example is known, in time slot format mapping table different time-gap form TPC territory original position relative to the original position of time slot be biased difference N(here N be greater than 0 integer) individual symbol, namely in different DPCH time slot, stagger, as shown in accompanying drawing 3-d in the position of TPC.Owing to staggering in the position of TPC instruction on time slot of each subscriber equipment, base station is equivalent to transmission of staggering according to this configuration when each subscriber equipment described sends described TPC instruction.
10 symbols are comprised with a time slot, it is example that each symbol takies 256 chips (chip), suppose have 10 subscriber equipmenies and UE0 to UE9, front 1 symbol the 1st 256 chips of the time slot of UE0 can be configured to the position of TPC instruction on time slot of UE0 by RNC when configuring TPC instruction, the 2nd of the time slot of UE1 symbol i.e. the 2nd 256 chip are configured to the position of TPC instruction on time slot of UE1, by the 3rd of the time slot of UE2 the symbol i.e. the 3rd 256 chips TPC instruction position on time slot being configured to UE2 etc., stagger a symbol successively in the position of TPC instruction on its time slot of remaining subscriber equipment, as shown in accompanying drawing 3-e, that RNC configures 10 subscriber equipmenies position of TPC instruction on time slot separately and to stagger schematic diagram.Original position due to the time slot of 10 subscriber equipmenies be alignment, therefore, when is staggered successively in its TPC instruction position on time slot a symbol that is 256 chip time, just staggered in the position of TPC instruction on time slot of 10 subscriber equipmenies.The configuration of such as accompanying drawing 3-e example is that this configuration of staggering of the position of TPC instruction on the time slot of alignment of each subscriber equipment is indicated to base station by RNC.
From the method that the invention described above embodiment provides, what indicate due to radio network controller (RNC) is configured to DPCH channel time slot format index, and DPCH channel time slot format is determined according to time slot format mapping table and described time slot format index in base station, therefore, even if when uplink transmission time grid alignment, for downward special physical channel, can not align in its downlink times interval, thus substantially reduce descending peak-to-average force ratio.
It should be noted that, in the above-described embodiment, due to RNC and whether uncertain subscriber equipment and base station support this configuration, therefore, in embodiments of the present invention, base station and each subscriber equipment can report its ability information to RNC, and RNC receives the ability information of ability information that described base station reports and UE, and described ability information is used to indicate each subscriber equipment and base station and supports the position of TPC instruction on time slot of each subscriber equipment to stagger this configuration.Such as, in an above-mentioned embodiment, base station and each user equipment to report support are used to indicate the ability information that the downlink DPCH slot form of the enhancing of accompanying drawing 3-e example supported by subscriber equipment.In embodiments of the present invention, subscriber equipment can be carried at wireless heterogeneous networks (Radio Resource Control to the ability information that RNC reports, RRC) connection establishment request (CONNECTION REQUSET) message or RRC connection establishment complete in (CONNECTION SETUP COMPLETE) or other RRC information, and base station can be carried in the message such as audit response message (AUDIT RESPONSE) or resource status Indication message (RESOURCE STATUS INDICATION) to the described ability information that RNC reports.
Poor owing to there are 1024 fixing chips between up DPCCCH/DPDCH/E-DPCCH/E-DPDCH and descending DPCH/F-DPCH, therefore, uplink transmission time interval (Transmission Time Interval between each subscriber equipment, TTI) during alignment, its descending TTI also must align, thus causes descending peak-to-average force ratio too high.In order to address this problem, in an alternative embodiment of the invention, provide the method for a kind of uplink and downlink frame timing, its flow process as shown in Figure 4.The method flow of the uplink and downlink frame timing of accompanying drawing 4 example comprises:
S401, base station receives the biased offset of radio network controller (RNC) instruction;
S402, uplink and downlink frame timing difference is determined according to offset in base station.
The biased offset of the RNC instruction that base station receives is T 1offset, wherein, according to offset, base station determines that uplink and downlink frame timing difference comprises: base station determines that uplink and downlink frame timing difference is 1024+T 1offsetindividual chip, its value can be the integral multiple of 256 chips (chip), such as, T 1offsetin set { 2 × 256,3 × 256,4 × 256,5 × 256,6 × 256,7 × 256,8 × 256, appoint in 9 × 256} and get a number, its unit is chip (chip), then the timing difference owing to existing between up DPCCCH/DPDCH/E-DPCCH/E-DPDCH and descending DPCH/F-DPCH becomes 1024+T by 1024 chips originally fixed 1offsetchip, therefore, when the up TTI between each subscriber equipment aligns, its descending TTI no longer aligns, thus it is too high to avoid descending peak-to-average force ratio.Or the biased offset of the RNC instruction that base station receives is T 2offset, according to offset, base station determines that uplink and downlink frame timing difference comprises: base station determines that uplink and downlink frame timing difference is 4+T 2offsetindividual symbol, here T 2offsetbe not less than 0, its unit is-symbol.
It should be noted that, the biased offset of the RNC instruction that base station receives is T 3offset, according to offset, base station determines that uplink and downlink frame timing difference is T 3offsetindividual chip, described T 3offsetbe not less than 1024 chips; Or the biased offset of the RNC instruction that base station receives is T 4offset, according to offset, base station determines that uplink and downlink frame timing difference is T 4offsetsymbol, described T 4offsetbe not less than 4 symbols, also belong to protection scope of the present invention, follow-up described scheme is all according to T 1offsetand T 2offsetfor introducing, to T for example 3offsetand T 4offsetrepeat no more.
In the embodiment staggered in the position of TPC instruction on time slot configuring each subscriber equipment due to above-mentioned RNC, realized by 256 chips that the initial time of carrying TPC instruction is staggered, therefore, (High Speed Uplink Packet Access may be accessed to high speed uplink downlink packet, HSPA) timing of correlated channels has an impact, and proposes the method eliminating or reduce impact below pointedly.
To strengthen special mixing automatic feedback channel (E-DCH Hybrid ARQ Indicator Channel, E-HICH) be example, E-HICH to be spreading factor be 128 down physical channel, for carrying the confirmation of up E-DPDCH data/do not confirm that (Acknowledgment/Negative Acknowledge, ACK/NACK) indicates.
When up TTI is configured to 2ms, an ACK or NACK instruction is carried on continuous 3 time slots and sends.When up TTI is configured to 2ms, E-HICH and Primary Common Control Physical Channel (Primary Common Control Physical Channel, P-CCPCH) timing difference τ e-HICH, nfor , wherein, τ dPCH, nfor the timing difference of descending DPCH or F-DPCH radio frame boundaries and P-CCPCH frame boundaries, it is right to represent round downwards.If keep existing timing relationship constant, the difference of up-downgoing timing difference and ULDPDCH/DPCCH/E-DPDCH and descending DPCH frame boundaries expands to 1024+offset by 1024 chips (chip), be equivalent to E-DPDCH frame boundaries pusher, the processing time then leaving base station (NodeB) for just decreases, herein, biased offset is identical with the biased offset in previous embodiment, and the processing time of NodeB is the time interval starting to send E-HICH after subscriber equipment sends E-DPDCH to base station.The adverse effect caused to eliminate the processing time leaving NodeB for reduce, in an embodiment of the invention, NodeB can by T 1offsetor T 2offsetfor the timing difference τ of revised E-HICH and P-CCPCH e-HICH, n, the timing difference τ of revised E-HICH and P-CCPCH e-HICH, nby original become chip, or, the timing difference τ of revised E-HICH and P-CCPCH e-HICH, nby original become
chip, in above-mentioned expression formula, τ dPCH, nfor under
The timing difference of row dedicated physical channels and descending P-CCPCH.The another kind of solution of the adverse effect that above-mentioned elimination causes because the processing time leaving NodeB for reduces keeps existing timing relationship constant, but its prerequisite is that the disposal ability of hypothesis base station is enough strong, can feeding back ACK/NACK in time, or network side configuration offset and τ dPCH, ntime, the maximum processing time ensureing to leave for base station is not less than the minimum treat time of base station.
Special Relative Grant Channels (Serving E-DCH Relative Grant CHannel is strengthened again to serve, Serving E-RGCH) be example, what Serving E-RGCH carried is relative authorization, be used for control ascending reinforced special channel (Enhanced-Dedicated CHannel, E-DCH) uplink authorization.When up TTI is 2ms, the timing difference of E-RGCH and P-CCPCH frame boundaries is , wherein, τ dPCH, nfor the timing difference of descending DPCH or F-DPCH radio frame boundaries and P-CCPCH frame boundaries, it is right to represent round downwards.If keep existing timing constant, expand to 1024+offset, be namely equivalent to E-DPDCH frame boundaries pusher, so in E-RGCH entry-into-force time of relative authorization (Relative Grant, RG) with regard to time delay, so the processing time leaving subscriber equipment for reduce.In order to address this problem, a kind of method that the embodiment of the present invention provides is that NodeB can by T 1offsetor T 2offsetfor the timing difference τ of revised E-HICH and P-CCPCH e-HICH, n, the timing difference τ of revised E-RGCH and P-CCPCH e-RGCH, nby original become
chip, in above-mentioned expression formula, τ dPCH, nfor the timing difference of downlink physical dedicated channel and descending P-CCPCH.
The another kind of solution of the adverse effect that above-mentioned elimination causes because the processing time leaving subscriber equipment for reduces is by network configuration offset and τ dPCH, n, the processing time guaranteeing to leave for subscriber equipment is not more than current maximum time, or keeps existing timing relationship constant, and think that the disposal ability of subscriber equipment is enough strong, RG can come into force in time.
Special Relative Grant Channels (Non-Serving E-DCH Relative Grant CHannel is strengthened again with non-serving, Non-Serving E-RGCH) be example, non-serving E-RGCH is the E-RGCH that non-serving radio link is concentrated, be used for controlling up E-DCH relative authorization, a RG takies continuous 15 time slots, non-serving E-RGCH and P-CCPCH have fix 5120 chip poor.E-RGCH sends RG No. i-th radio frames, so RG acts on the time point of up E-DPDCH is t ' number wireless sub-frame corresponding to the i-th+1+s radio frames of E-DPDCH, i.e. E-RGACH(i)=>E-DPDCH(i+1+s ', t '), wherein s ', t ' are defined as:
if keep existing timing constant, expand to 1024+offset, be equivalent to E-DPDCH frame boundaries pusher, so in E-RGCH the entry-into-force time of RG with regard to time delay, so the processing time leaving subscriber equipment for reduce.In order to address this problem, a kind of method that the embodiment of the present invention provides is that base station is by T 1offsetor T 2offsetfor the entry-into-force time of non-serving E-RGCH RG information when No. i-th radio frames sends relative authorization RG information, non-serving E-RGCH described RG information entry-into-force time when No. i-th radio frames sends relative authorization RG information is revised as the t wireless sub-frame of the i-th+1+s radio frames sent at E-RGCH, and described s is described t is or entry-into-force time of RG information is the t wireless sub-frame of the i-th+1+s radio frames sent at E-RGCH, and described s is , described t is , in above-mentioned expression formula, τ dPCH, nfor downlink physical dedicated channel and down channel and descending timing difference.
The another kind of solution of the adverse effect that above-mentioned elimination causes because the processing time leaving subscriber equipment for reduces supposes that the disposal ability of subscriber equipment is enough strong, thus can ensure that RG comes into force immediately, or by network configuration offset and τ dPCH, n, the processing time guaranteeing to leave for subscriber equipment is not more than current maximum time.
Again to strengthen special absolute grant channel (E – DCH Absolute Grant CHannel, E-AGCH) be example, that E-AGCH carries is absolute grant (Absolute Grant, AG) information, be used for controlling up E-DCH absolute grant, when up TTI is 2ms, AG takies continuous 3 time slots (slot); E-AGCH and P-CCPCH has and fixes 5120 chip differences.E-AGCH sends at the j work song frame that No. i-th radio frames is corresponding, then the AG entry-into-force time puts as t ' work song frame corresponding to the i-th+s ' number radio frames of E-DPDCH, i.e. E-AGCH(i, j)=>E-DPDCH(i+s ', t '), wherein s ' and t ' is defined as respectively:
with
