Description
Technical field
The present invention relates to communication technical field, the uplink information that relates in particular to a kind of terminal sends timing method, equipment and system.
Background technology
LTE (Long Term Evolution, Long Term Evolution) system is 3G (3rd Generation, 3-G (Generation Three mobile communication system)) evolution, LTE improves and has strengthened the aerial access technology of 3G, and adopt OFDM (Orthogonal Frequency Division Multiplexing, OFDM) and MIMO (Multiple Input Multiple Output, multiple-input and multiple-output) as the standard of wireless network evolution.Wherein, LTE can provide the peak rate of descending 100Mbit/s and up 50Mbit/s under 20MHz spectral bandwidth, has improved the performance of Cell Edge User, has improved cell capacity, and has reduced system delay.Along with increasing rapidly of number of users of mobile terminal amount, terminal use's volume of business is exponential increase, in order to meet the terminal use's who continues to increase business demand, business and the needed more peak value speed of application that need to provide larger bandwidth to meet terminal use.In following mobile communication system, for example, in B3G (Beyond three Generation, rear three generations) or in LTE-A (LTE-Advanced, senior LTE), system will provide higher peak data rate and cell throughout, also needs larger bandwidth simultaneously.Unassigned bandwidth below 2GHz seldom at present, the part or all of bandwidth that LTE-A system (take LTE-A system describe for example) needs can only be in higher frequency range, and in actual application, frequency range is higher, it is faster that radio wave propagation is decayed, and transmission range is shorter; Under same overlay area, guarantee continuous covering, need more base station.Because base station has higher cost, when a lot of base station of needs, will increase the cost that creates network.In order to address the above problem, each manufacturer and standardization body are incorporated into relaying (relay) in cellular system, thereby increase the region covering.
Concrete, in LTE-A system, to introduce trunking, this trunking (for example, relay node in band) feature having includes but not limited to: trunking, by controlling community, makes from terminal, and each community is all independently communities, each community has the physical district ID of increase, and trunking can send the information such as the synchronizing channel, reference symbol of oneself; And for the operation of single subdistrict, terminal will directly receive schedule information and HARQ (Hybrid Automatic RepeatRequest from trunking, mixed automatic retransfer request) feedback information, and the ascending control information of transmitting terminal is to trunking, for example, the ascending control information of terminal comprises SR (Scheduling Request, dispatch request)/channel quality indicator (CQI) (Channel Quality Indicator, channel quality is indicated)/ACK (ACKnowledge Character, acknowledge character) etc.
Further, the introducing of trunking makes the wireless link of the mobile communication system based on Relay have three: be respectively the direct projection link (direct link) between base station and terminal, back haul link between base station and trunking (backhaul link), and the access link between trunking and terminal (accesslink), when considering the interference-limited of wireless communication signals, above-mentioned three links need to be used the Radio Resource of quadrature; And because the transmitting-receiving process of trunking is all mode of operations of half-duplex time-division, be that back haul link and access link are at TDD (Time Division Duplexing, time division duplex) in frame structure, be to take different time slots, and direct link and back haul link are can be coexistent, as long as running time-frequency resource quadrature.
In addition, as shown in Figure 1, be uplink/downlink frames timing relationship schematic diagram in LTE system, the relation between this up-downgoing is regularly specially, and the uplink transmission frame of terminal regularly constantly, need to regularly constantly add a lead at the descending received frame of terminal.As can be seen from Figure 1, this lead is (N
tA+ N
tAoffset) * T
s, wherein, this N
tAand N
tAoffsetthe parameter of Timing Advance, this N
tAby propagation delay, caused, and this N
tAoffsetto cause switching time, for FDD (Frequency Division Duplex, Frequency Division Duplexing (FDD)), N
tAoffset=0, and for FDD and the TDD of half work, N
tAoffset=614.
In realizing process of the present invention, inventor finds at least to exist in prior art following shortcoming:
Owing to existing regularly and having mentioned between the introducing of trunking and the timing of the uplink frame of trunking and downlink frame timing, the Timing Advance of the terminal of therefore being served by trunking has increased with respect to former Timing Advance, added value is the Timing Advance of trunking, and in prior art terminal obtain uplink frame regularly and downlink frame regularly between during Timing Advance, the Timing Advance of this increase is not considered.
In addition, in order to increase the resource that trunking can use at back haul link or to make the trunking can up transmission detecting pilot frequency, up backhaul subframe timing and the descending backhaul subframe timing of trunking be delayed respectively.Because access link subframe timing aligns with back haul link subframe timing, so the timing of the uplink frame of trunking and downlink frame are regularly delayed respectively, when the two the value of delaying is not identical, the Timing Advance of trunking needs to change, thereby the Timing Advance of terminal also needs to adjust, and when terminal obtains the Timing Advance between up-downgoing regularly in prior art, do not consider the difference of this value of delaying yet.

The embodiment of the present invention two provides a kind of uplink information of terminal to send timing method, and in the embodiment of the present invention, the method can, for fdd mode, also can, for tdd mode, as shown in Figure 3, comprise the following steps:
In this step, under fdd mode, this trunking need to obtain respectively the value of RTT1, Δ, RTT2; Under tdd mode, this trunking need to obtain respectively the value of RTT1, Δ, T1, RTT2.
This acquisition process comprises: (1), under fdd mode or tdd mode, trunking passes through the downlink synchronous signal of Sampling network side apparatus and/or the downlink frame timing that public guide frequency obtains himself.Wherein, this network equipment includes but not limited to RNC (Radio Network Controller; radio network controller), NB (Node B; Node B), eNB, base station etc.; it should be noted that; this network equipment is not limited to the said equipment, and all equipment that is positioned at network side is all within protection range of the present invention.For convenience of description, in the embodiment of the present invention, this network equipment all be take base station and is described as example.Concrete, trunking sends random access leader sequence according to descending timing to base station, and by the accidental access response from base station, obtains uplink timing advance from base station.Wherein, the uplink timing advance in this step is a part for total uplink timing advance; Under fdd mode, the uplink timing advance getting in this step equals 2 times of propagation delay between base station and trunking, with RTT1, represents; Under tdd mode, this step is obtained to arrive and is starved 2 times (RTT1) that uplink timing advance equals propagation delay between base station and trunking, with T1 switching time that receives transmission of base station, sum.(2) base station obtains the difference Δ being worth after the descending backhaul subframe timing of trunking and the additional fixed response time between up backhaul subframe timing, because the up-downgoing of access link is regularly alignd with the timing of back haul link, so the difference being worth after the timing of the downlink frame of trunking and uplink frame additional fixed response time is regularly also Δ; For trunking, in order to save the resource of descending backhaul subframe, trunking need to be delayed TA1 by descending backhaul subframe timing; Same, in order to save the resource of up backhaul subframe and to make trunking can send sounding reference symbol, trunking need to be delayed TA2 by up backhaul subframe timing.Concrete, there is constant time lag situation in the backhaul subframe in LTE-A system, as shown in Figure 4, descending backhaul subframe timing situation for trunking, in Fig. 4, trunking is in descending backhaul subframe, the 1st orthogonal frequency division multiplex OFDM symbol and the 2nd OFDM symbol are for sending downlink data to terminal, 13 OFDM symbols of the 4th OFDM symbol to the are for receiving the downlink data from base station, for descending backhaul subframe, need GP (protection interval) that time switching to reception (Tx-Rx) for process of transmitting is provided, or receive the switching of transmission (Rx-Tx), can find out, GP may need to take two OFDM symbols (i.e. the 3rd OFDM symbol and the 14th OFDM symbol) of the descending backhaul subframe of trunking, thereby has caused the wasting of resources.Concrete, the GP using when the switching of Tx-Rx, with, the GP that the switching of Rx-Tx is used, when sum is less than the length of an OFDM symbol, by the descending backhaul subframe timing of trunking is delayed to TA1, last OFDM symbol (the 14th OFDM) can be used for back haul link downlink transfer, only need an OFDM symbol (the 3rd OFDM), thus the resource of having saved an OFDM symbol.Wherein, the value of this TA1 is not less than the GP that Rx-Tx is used, and makes after time delay TA1, and last OFDM symbol can occupiedly again not switch GP as Rx-Tx.Further, as shown in Figure 5, up backhaul subframe timing situation for trunking, in Fig. 5, trunking is in up backhaul subframe, and 13 OFDM of the 2nd OFDM to the are for send upstream data to base station, for up backhaul subframe, need GP to provide the time for sending to the switching of reception (Tx-Rx), or receive the switching of transmission (Rx-Tx); Can find out, GP may need to take two OFDM symbols (i.e. the 1st OFDM symbol and the 14th OFDM) of the up backhaul subframe of trunking, thus caused the wasting of resources and in the end on an OFDM symbol trunking cannot send the sounding reference symbol R-SRS of trunking.Concrete, the GP using when the switching of Tx-Rx, with, the GP that the switching of Rx-Tx is used, when sum is less than the length of an OFDM symbol, by the up backhaul subframe timing of trunking is delayed to TA2, last OFDM symbol (the 14th OFDM symbol) can be used for back haul link uplink, can be for the transmission of R-SRS, now, only need an OFDM symbol (the 1st OFDM symbol), thus the resource of also having saved an OFDM symbol.Wherein, the value of this TA2 is not less than the GP that Rx-Tx is used, and makes after time delay TA2 the GP that last OFDM symbol there will be no Rx-Tx to use.
(3) base station is by the value of RRC signaling or this TA1 of broadcast informed relay devices and TA2.Wherein, the uplink timing advance for terminal (being positioned at the terminal under trunking), need to increase Δ=TA1-TA2.Can find out, after this step finishes, this trunking will be known the value of TA1 and TA2, and can calculate Δ=TA1-TA2.
(4) terminal is by detecting the downlink synchronous signal of trunking and/or the descending timing that public guide frequency obtains access link.Terminal sends random access leader sequence according to descending timing to trunking, via node is determined the propagation delay time between trunking and terminal according to the random access leader sequence receiving, thereby determine the uplink timing advance RTT2 of access link, this RTT2 is 2 times of propagation delay between trunking and terminal.
As shown in Figure 6, uplink information transmission timing relationship for the terminal under fdd mode, in this timing relationship, consider the propagation delay time between base station and trunking, with the timing difference of the descending timing of trunking with up timing, the up timing of trunking will shift to an earlier date RTT1+ Δ with respect to descending timing, and wherein RTT1 is 2 times of propagation delay time between base station and trunking, Δ be after descending fixed response time with up fixed response time after poor, on the occasion of.And the timing of terminal is by the timing alignment according to trunking, therefore cause the up timing of terminal, with respect to descending timing advance RTT1+ Δ+RTT2, this RTT2 is 2 times of propagation delay between trunking and terminal.Wherein, RTT1, Δ value (being TA1-TA2 value) and RTT2 value in above-mentioned steps, have been got; In this step, this trunking can carry above-mentioned uplink timing advance information middle in terminal sends timing advance order.
As shown in Figure 7, uplink information transmission timing for the terminal under tdd mode, in this timing relationship, consider propagation delay between base station and trunking and the switching time of base station, and the timing difference of considering the descending timing of trunking and up timing, the up timing of trunking will shift to an earlier date RTT1+T1+ Δ with respect to descending timing, wherein RTT1 is 2 times of propagation delay time between base station and trunking, T1 is the time that up-downgoing switching is carried out in base station, Δ be after descending fixed response time with up fixed response time after poor, on the occasion of.And the timing of terminal is according to the timing alignment of trunking, therefore cause the up timing of terminal, with respect to descending timing advance RTT1+T1+ Δ+RTT2, this RTT2 is 2 times of propagation delay between trunking and terminal.In the embodiment of the present invention, while being switched to descending sub frame due to the sub-frame of uplink of trunking, have enough GP that the time is provided, in uplink timing advance, do not comprise the switching time of trunking, uplink timing advance only includes RTT1+T1+ Δ+RTT2.Wherein, RTT1, T1 value, Δ value (being TA1-TA2 value) and RTT2 value in above-mentioned steps, have been got; In this step, this trunking can carry above-mentioned uplink timing advance information middle in terminal sends timing advance order.
In the embodiment of the present invention, for fdd mode, if trunking adopts transparent mode to send this uplink timing advance information to terminal, the uplink timing advance information that trunking sends to terminal is the parameter of two Timing Advances, is respectively N

tAoffset=0.
Further, if trunking adopts nontransparent mode to send this uplink timing advance information to terminal, the uplink timing advance information that trunking sends to terminal is the parameter of two Timing Advances, is respectively N
tAand N
tAoffset, during fdd mode, this N
tAwith minimum time unit T long-pending equal RTT2, NTAoffset=0.Now, in the uplink timing advance information that trunking sends to terminal, also need to comprise Δ value and RTT1, this trunking can by Δ value and RTT1 and directly send to terminal, also Δ value and RTT1 can be sent to respectively to terminal; Under fdd mode, trunking also needs to terminal notice RTT1 and Δ; Wherein, this advice method can be for defining other Timing Advance parameter, this parameter and minimum time unit long-pending equal (RTT1+ Δ); In addition, if Δ is not equal to 0, can define two other Timing Advance parameters, the integration of these two parameters and minimum time unit T does not equal RTT1 and Δ yet.
Further, above-mentioned minimum time unit T=m*Ts, m=1,2,3..., Ts=1/ (15000*2048) second.
In addition,, for tdd mode, if trunking adopts transparent mode to send this uplink timing advance information to terminal, the uplink timing advance information that trunking sends to terminal is the parameter of two Timing Advances, is respectively N
tAand N
tAoffset, during FTDD pattern, this N
tAwith minimum time unit T long-pending equal (RTT1+T1+ Δ+RTT2), N
tAoffset=0.
Further, if trunking adopts nontransparent mode to send this uplink timing advance information to terminal, the uplink timing advance information that trunking sends to terminal is the parameter of two Timing Advances, is respectively N
tAand N
