Description
Technical field
The present invention relates to the communications field, in particular to a kind of measuring reference signals sending method and device.
Background technology
Radio frames (radio frame) bag in Long Term Evolution (Long Term Evolution, referred to as LTE) system
Include FDD (Frequency Division Duplex, referred to as FDD) pattern and time division duplex (Time Division
Duplex, referred to as TDD) pattern frame structure.The frame structure of fdd mode, as shown in figure 1, one 10 milliseconds
(ms) radio frames by 20 length be 0.5ms, numbering 0～19 time slot (slot) composition, time slot 2i and 2i+1
Subframe (subframe) i of the composition length for 1ms.The frame structure of tdd mode a, as shown in Fig. 2 10ms
Radio frames be made up of the field (half frame) of two a length of 5ms, field includes 5 length for 1ms's
Subframe, subframe i are defined as the time slot 2i and 2i+1 of 2 a length of 0.5ms.
In above two frame structure, for general cyclic prefix (Normal Cyclic Prefix, referred to as Normal CP),
One time slot includes the symbol that 7 length are 66.7 microseconds (us), wherein the CP length of first symbol is 5.21us,
The CP length of remaining 6 symbol is 4.69us；For extended cyclic prefix (Extended Cyclic Prefix, referred to as
Extended CP), a time slot includes 6 symbols, and the CP length of all symbols is 16.67us.Unit of time Ts
It is defined as Ts=1/ (15000 × 2048) second, the uplink-downlink configuration of support are seen below shown in table 1, in a radio frames
Each subframe, " D " is represented and is exclusively used in the subframe of downlink transfer, and " U " represents the subframe for being exclusively used in uplink, " S " table
Show for descending pilot frequency time slot (Downlink Pilot Time Slot, referred to as DwPTS), protection interval (Guard Period,
Referred to as GP) and uplink pilot time slot (Uplink Pilot Time Slot, referred to as UpPTS) these three domains is special
The length of subframe, DwPTS and UpPTS is shown in Table 2, and their length obeys DwPTS, GP and UpPTS
Three's total length is 30720Ts=1ms.By 2 time slots 2i and 2i+1, each subframe i represents that each time slot is long
For Tslot=15360Ts=0.5ms.
LTE TDD support the up-downgoing switching cycle of 5ms and 10ms.If the downstream-to-upstream transfer point cycle is 5ms,
Special subframe can be present in two fields；If downstream-to-upstream transfer point cycle 10ms, special subframe are existed only in
In first field.Subframe 0 and subframe 5 and DwPTS are always used for downlink transfer.UpPTS and immediately following in special
Subframe after subframe is exclusively used in uplink.
1 UL/DL of table is configured
2 special subframe of table configures (DwPTS/GP/UpPTS length)
In LTE, physical downlink control channel PDCCH is used to carry uplink and downlink schedule information, and ascending power
Control information.Downlink Control Information (Downlink Control Information, referred to as DCI) form (format)
Be divided into DCI format 0,1,1A, 1B, 1C, 1D, 2,2A, 3,3A etc..Base station (e-Node-B, referred to as
For eNB) (User Equipment, referred to as UE, are also called use can to pass through Downlink Control Information configurating terminal device
Family equipment), or the configuration of terminal unit acceptance high-rise (higher layers), configure also referred to as by high-level signaling
UE。
The broadcast message of LTE system is divided into main message blocks (MIB) and System information block (SIB), and wherein MIB is in thing
In reason broadcast channel (PBCH) transmission, SIB transmit on Physical Downlink Shared Channel (PDSCH) (be also called SI,
That is Scheduled Information).According to scheduling requirement (for example：Cycle) difference, these SIB information divide again
Transmit on several SI, system at least supports 4 SI (i.e. SIB-1, SIB-2, SIB-3, SIB-4)
Measuring reference signals (Sounding Reference Signal, referred to as SRS) are between a kind of terminal unit and base station
For measuring the signal of radio channel information (Channel State Information, referred to as CSI).In Long Term Evolution
In system, the parameter such as bandwidth, frequency domain position, sequence cyclic shift, cycle and sub-frame offset that UE is indicated according to eNB,
Timing sends uplink SRS on last data symbol for sending subframe.ENB judges UE according to the SRS for receiving
Up CSI, and the operation such as frequency domain selection scheduling, close-loop power control is carried out according to the CSI for obtaining.
In same SRS bandwidth, multiple UE can use different cyclic shifts, Ran Houtong in same frequency comb
Cross code division multiplexing and send SRS, it is also possible to which two UE send SRS by frequency division multiplexing in different frequency combs.Lift
For example, in LTE system, the UE of SRS is sent in certain SRS bandwidth (4 RB), it is possible to use
Cyclic shift has 8, it is possible to use frequency comb be 2, thus a total of 16 of UE can be used to send SRS
Resource, that is to say, that in this SRS bandwidth, at most can send 16 SRS simultaneously.Due in LTE systems
Uplink single user multiple-input and multiple-output (Single User Multiple Input Multiple Output, abbreviation are not supported in system
For SU-MI MO), UE can only have an antenna to send SRS at each moment, so a UE only needs to a SRS
Resource, therefore, in above-mentioned SRS bandwidth, system at most can be with 16 UE of concurrent multiplexing.
Senior LTE (LTE-Advanced, referred to as LTE-A) system is the evolution system of future generation of LTE system,
In up support SU-MIMO, and 4 antennas can be at most used as up transmitting antenna.That is, UE
SRS can be sent on many antennas simultaneously in synchronization, and eNB is needed according to the SRS received on every antenna
To estimate the state on every channel.
Propose in the research of existing LTE-A：In uplink communication, it should using non-precoded (i.e. antenna is proprietary)
SRS.Now, when UE sends the SRS of non-precoded using multiple antennas, the SRS resource required for each UE
Will increase, also result in system and can have been declined with the UE quantity of concurrent multiplexing.Additionally, original except retaining LTE
Cycle (periodic) send SRS, Downlink Control Information or high-level signaling can also be passed through and configure UE aperiodics
(aperiodic) send SRS.
For example, in certain SRS bandwidth (4 RB), if each UE sends SRS using 4 antennas, that
Number of resources required for each UE is exactly 4.According to the SRS resource that can be supported in said one SRS bandwidth
Number is total up to 16, then in this SRS bandwidth, the UE numbers that can be multiplexed just are reduced to 4.Can in system
With the number of users of concurrent multiplexing by 1/4 as original LTE.In existing LTE-A Release 10 (LTE-A versions 10)
Research in propose, UE can pass through high-level signaling (also referred to as triggering by trigger type 0) or Downlink Control Information
(also referred to as being triggered by trigger type 1) both triggering modes send SRS, are week based on high-level signaling triggering
Phase SRS, is SRS aperiodic based on Downlink Control Information triggering.Aperiodic be increased in LTE-A Release 10
The mode of SRS is sent, the utilization rate of SRS resource is improved to a certain extent, the motility of scheduling of resource is improved.
In following LTE-A Release 13 (LTE-A versions 13) researchs, in the MIMO (Full for configuring complete dimension
Dimension-MIMO, referred to as FD-MIMO) or/a large amount of antennas MIMO (Massive-MIMO) scene
Under, as TDD channel reciprocities are to the increase of SRS measurement demands and increasing for users multiplexing number, existing SRS
Multiplexing capacity has been difficult to meet demand.
Proposing in the related increases the mode of the time-domain symbol (such as UpPTS) for being used to sending SRS, however,
How SRS is sent in increased time-domain symbol, not yet propose effective solution at present.
