Physical Uplink Shared Channel uses single antenna port transmission in LTE system.One system-frame (frame) includes 10 Subframe (subframe), each subframe include 2 time slots (slot).Fig. 3 is the routine in a time slot according to correlation technique The schematic diagram of cyclic prefix, as shown in figure 3, for conventional cyclic prefix (Normal CP, Normal Cyclic Prefix), Each time slot is made up of 6 data symbols and 1 demodulated reference signal.Fig. 4 is in a time slot according to correlation technique The schematic diagram of extended cyclic prefix, as shown in figure 4, for extended cyclic prefix, each time slot is solved by 5 data symbols and 1 Reference signal is adjusted to be formed.

For demodulated reference signal DMRS by a Sequence composition on frequency domain, the sequence is a circulation of reference signal sequence Displacement.In order to be randomized inter-cell interference, the reference signal sequence of demodulated reference signal configures according to network side, it is possible to achieve base (Sequence hopping) is redirected in the sequence of time slot or sequence group redirects (Group hopping), when this mode is also known as SGH (Sequence Group Hopping) mode that gap redirects.That is, configured according to network side, a user equipment is at one Demodulated reference signal in subframe on two time slots is different, and pattern is redirected in a system-frame at any time according to certain Gap changes.

In time slot n_sIn, the cyclic shift amount α of demodulated reference signal_λFor：α_λ=2 π n_cs,λ/ 12, wherein,In a radio frames, n_s=0,1 ..., 19；Configured by higher level parameters,Configured by uplink scheduling information, referred to as up DMRS cyclic shifts.n_PN(n_s) by puppet with Machine maker generates, and is with time slot n_sThe parameter of change, is embodied asPseudorandom sequence Column-generation device initializes once in each radio frames, and primary condition is Initialization value is relevant with affiliated cell ID, is the proprietary parameter of cell.Wherein,For cell ID, Δ_ssFor high level configuration Parameter.

Uplink scheduling information is carried on Physical Downlink Control Channel, with certain descending control information format (Downlink Control Information format, referred to as DCI format) target UE is sent to by network side.In LTE In system, descending control information format is divided into following several：DCI format 0,1,1A, 1B, 1C, 1D, 2,2A, 3,3A etc., its In, DCI format 0 include uplink scheduling information, for indicating Physical Uplink Shared Channel PUSCH scheduling.

LTE-Advanced systems (abbreviation lte-a system) are the evolution systems of future generation of LTE system.In lte-a system, When Physical Uplink Shared Channel is transmitted using multi-antenna port, the DMRS of each layer data is equally prelisted with each layer data Code.And the demodulated reference signal of different layer datas, including single user multi-input multi-output system (SU-MIMO) same user is set The demodulated reference signal of standby multi-layer data, and multiuser mimo system (MU-MIMO) multiple user equipmenies are more The demodulated reference signal of layer data, by using different demodulated reference signal cyclic shifts (CS) and/or orthogonal mask (Orthogonal Cover Code, referred to as OCC) is orthogonalized, with distinguish user's space multiplexing different layer datas or Person distinguishes different users.Wherein, orthogonal mask OCC is [+1 ,+1] and [+1, -1], acts on a subframe (Subframe) Demodulated reference signal on interior two time slots (Slot).User is matched for the MU of different-bandwidth, OCC can only be used to different User is orthogonalized, and therefore, the MU pairings number of users maximum of support is only 2.

At present, in the Standard Edition that 3GPP is formulated, the version of LTE standard is the 8th edition (Release 8) and the 9th edition (Release 9), the version of LTE-A standards is the 10th edition (Release 10), is abbreviated as Rel-8, Rel-9 and Rel- respectively 10, LTE-A standards may also include later release, such as Rel-11/12/13/14.At present in Rel-10 versions, network side can To indicate that the circulation for scheduled PUSCH demodulated reference signal moves by DCI format 0 and DCI format 4 Position/OCC information, as shown in table 3.

Table 3

Table 3 is up associated DC I format cyclic shift region[w^(λ)(0) w^(λ)(1)] mapping table,For the value of up DMRS cyclic shifts, descending control signaling dynamic instruction is up when corresponding upstream space is multiplexed The cyclic shift value of each layers of DMRS, λ are the index of layer, when using orthogonal mask OCC to demodulated reference signal orthogonalization, network Side needs to carry out joint-detection to the demodulated reference signal in a subframe on two time slots, thus requires that a user equipment exists Demodulated reference signal in one subframe on two time slots must be the same.In this case, it is impossible to during using in LTE system The SGH modes that gap redirects.But in order to be randomized inter-cell interference as far as possible, the SGH side that subframe redirects is proposed in correlation technique Formula.That is, configured according to network side, demodulated reference signal of the user equipment in a subframe on two time slots is the same , the demodulated reference signal in a system-frame in each subframe is different, and pattern is redirected at one according to certain Change in system-frame with subframe.

Measuring reference signals (Sounding Reference Signal, referred to as SRS) are a kind of terminal device and base station Between be used for measuring radio channel information (Channel State Information, referred to as CSI) signal.In Long Term Evolution In system, the parameter such as bandwidth, frequency domain position, sequence cyclic shift, cycle and sub-frame offset that UE indicates according to eNB, regularly exist Send and send uplink SRS on last data symbol of subframe.ENB judges the up CSI of UE according to the SRS received, and The operation such as frequency domain selection scheduling, close-loop power control is carried out according to obtained CSI.

In same SRS bandwidth, multiple UE can use different cyclic shifts in same frequency comb, then pass through Code division multiplexing send SRS, can also two UE in different frequency combs, SRS is sent by frequency division multiplexing.For example, exist In LTE system, SRS UE is sent in some SRS bandwidth (4 RB), the cyclic shift that can be used there are 8, can used Frequency comb be 2, thus a total of 16 resources that can be used to send SRS of UE, that is to say, that in this SRS bandwidth, 16 SRS can be at most sent simultaneously.Due to not supporting uplink single user multiple-input and multiple-output (Single in LTE system User Multiple Input Multiple Output, referred to as SU-MI MO), UE can only have a day at each moment Line sends SRS, so a UE only needs a SRS resource, therefore, in above-mentioned SRS bandwidth, system can at most answer simultaneously With 16 UE.

In following LTE-A Release 13 (LTE-A versions 13) researchs, SRS multiplexing capacity has been carried out further Enhancing, SRS transmission frequency can be combed from original 2 and expand to 4, while extend the symbol of the uplink pilot time slot of special subframe Number amount, expanded to from original 1 or 2 and be up to 6, to further enhance SRS multiplexing capacity in time domain.

In following LTE-A Release 14 (LTE-A versions 14) researchs, the MIMO (Full of complete dimension are being configured Dimension-MIMO, referred to as FD-MIMO) or/a large amount of antenna MIMO (Massive-MIMO) scene under, number of users is got over Come more, the demand of up MU pairing will be further increased, and matches user especially for the MU of different-bandwidth, how to send Row demodulated reference signal, it would be highly desirable to solve.In addition, how LTE-A versions 14 also strengthen the handling capacity of uplink in research, Upstream data is transmitted in research on the uplink pilot time slot of TDD special subframes, now how up solution is sent in special subframe Adjust reference signal, and urgent problem to be solved.

Therefore, how more pairing users in correlation technique for different-bandwidth send asking for uplink demodulation reference signal Topic, not yet proposes solution.
