Description

Sending method, device, terminal and the base station of Sounding Reference Signal

Technical field

The present invention relates to field of communication technology, more particularly to a kind of sending method of Sounding Reference Signal, device, Terminal and base station.

Background technique

Uplink reference signals are divided into two classes: one kind is demodulated reference signal, with PUSCH (Physical Uplink Shared Channel, physical uplink shared channel) or PUCCH (Physical Uplink Control CHannel, Physical uplink control channel) simultaneous transmission, for the demodulation of data, another kind of is SRS (sounding reference Signal, Sounding Reference Signal), it is mainly used for channel quality estimation, in order to which base station carries out frequency selective scheduling, separately On the one hand it can be used for power control enhancing or support the various function of initializing of the currently also unscheduled UE arrived, such as initially Change modulation and encoding scheme selection, initialization power control, timing advance and frequency semi-selective scheduling etc..Therefore, it is not Must be transmitted together with any physical channel, if transmitted together with physical channel, such as PUSCH, SRS may occupy it is different, Often bigger bandwidth.

In LTE, the SRS transmission of two classes is defined,

One kind is periodical SRS (periodic SRS, corresponding triggering type trigger type 0): 3GPP (3rd Generation Partnership Project, third generation partner program) protocol version Rel-8 in introduce, base station ENB is passed by the SRS that RRC (Radio Resource Control, wireless heterogeneous networks) signal deployment terminal UE carries out single Defeated or periodic transmission SRS stops to send request until receiving.The period that SRS is sent can be 2,5,10,20,40,80, 160 or 320ms.

Another kind of is aperiodicity SRS (aperiodic SRS, corresponding triggering type trigger type 1): 3GPP's It is introduced in protocol version Rel-10, that is, introduces the mode of Dynamic trigger SRS a kind of.For FDD (Frequency Division Dual, frequency division duplex), eNodeB can pass through DCI (Downlink Control Information, that is, Downlink Control Information) Format 0/4/1A triggers UE and sends aperiodicity SRS.For TDD (Time Division Duplexing, time division duplex), ENodeB can trigger UE by DCI format 0/4/1A/2B/2C/2D and send aperiodicity SRS.The mode of triggering is to make With the SRS request field in DCI.

Though for periodically or the configuration information of aperiodicity SRS, SRS, such as bandwidth, period and subframe Offset (subframe sent for determining SRS), Duration (instruction is to send single or period transmission), bandwidth, frequency domain Initial position, whether frequency hopping, transmission the comb teeth Transmission Comb (K that instruction uses_TCValue), Cyclic Shift (refers to Show cyclic shift), port number etc. be to be configured by RRC signaling.

With the introducing of 3D-MIMO (Multiple-Input Multiple-Output, Multiple Input Multiple Output), antenna Number becomes more, can be simultaneously using the directionality of vertically and horizontally dimension, so that more terminal multiplexings, the sky of He Geng great layer Between be multiplexing into possibility；SRS in order to support the spatial reuse of the more layer in more multiple terminals, for terminal channel information acquisition It is also required to be enhanced, the enhanced scheme of the SRS discussed in existing standardization includes:

It is being not used by PUSCH DMRS (Demodulation Reference Signal, demodulated reference signal) money SRS is transmitted on source；

In PUSCH transmitted over resources SRS；

Increase the number of SRS comb to be multiplexed more terminals

4Tx antenna switching transmission SRS

Precoding SRS

Increase SC-FDMA (the Single-carrier Frequency that SRS transmission is used in ascending pilot frequency UpPTs Division Multiple Access, single-carrier frequency division multiple access) quantity

Above-mentioned enhancing focuses primarily upon the transmission resource for increasing SRS, so as to send SRS for more terminals, separately It on the one hand also include that the SRS of uplink more antennas is supported to send.

However, the triggering mode of SRS only triggers two kinds by high-level signaling triggering and DCI, wherein for high-level signaling The mode of triggering needs to carry out to reconfigure transmission single or periodic SRS by the RRC signaling of some cycles.When only Need transient channel information without knowing long-term information in the case where, single configuration real-time it is poor.

For aperiodic triggering mode, several format of triggering mean to need for UE uplink or Downlink transfer could trigger aperiodic SRS；

Existing high-level signaling scheduling mode needs to wait the transmission of RRC signaling, and aperiodic triggering mode needs end End has data scheduled.

Specific embodiment

To keep the technical problem to be solved in the present invention, technical solution and advantage clearer, below in conjunction with attached drawing and tool Body embodiment is described in detail.

The present invention is triggered for existing SRS, and high-level signaling scheduling mode needs to wait the transmission of RRC signaling, Er Feizhou The triggering mode of phase needs terminal to have data scheduled, can not need to trigger single SRS transmission in base station, and counterpart terminal does not have Uplink and downlink data need the problem of triggering SRS when scheduled transmission, provide a kind of sending method of Sounding Reference Signal, In The not scheduled data transmission of terminal, can also trigger the transmission of SRS in real time, base station is enable to get the SRS of UE.

As shown in Figure 1, a kind of sending method of Sounding Reference Signal of first embodiment of the invention, comprising:

Step 11, the Downlink Control Information for the functional instructions field of setting that base station is sent is received；

Step 12, after the Downlink Control Information for receiving the functional instructions field of setting that base station is sent, if terminal is being worked as When not being transmitted across uplink scheduling request in the preset time period before the preceding moment, is sent and believed according to the Downlink Control Information Road detection reference signal SRS；

It should be understood that, when terminal needs to carry out reverse link traffic channel transmission, being asked by scheduling in LTE system Ask (scheduling request, SR) to eNodeB application uplink scheduling resource.After base station receives the scheduling request of terminal, Scheduling authorization can be sent for terminal, the transmission of PUSCH is dispatched by the DCI 0 or 4 transmitted for dispatching uplink data.Work as simultaneously When base station has downlink data to be sent to terminal, it will be dispatched by the DCI 0/1A/2B/2C/2D that dispatching downlink data are transmitted Terminal.

In the embodiment, when base station needs the channel information of terminal to be scheduled or pretreatment operation and and without reality When service data scheduling, a Downlink Control Information can be sent to UE.Functional instructions field is arranged in the Downlink Control Information, for referring to Show that the function of the Downlink Control Information, terminal determine whether that triggering terminal reports SRS according to the information of the function instructions field.Its In, function instructions field can be some bits newly increased, be also possible to the certain bits being multiplexed in existing DCI information field or The instruction that the certain states that can indicate of some information field complete function, for example, reuse the domain SRS request 1bit or 2bit, or reuse the M-bit etc. of resource allocation field.Terminal carries out the detection of normal control channel on subframe n, receives base The Downlink Control Information for the functional instructions field of setting sent of standing.After the Downlink Control Information for receiving base station transmission, root SRS is reported according to function instructions field instruction triggering terminal, and terminal is not sent in the preset time period before current time When crossing uplink scheduling request, terminal can send SRS according to the Downlink Control Information.Due to terminal before current time one Uplink scheduling request is not transmitted across in preset time period, it will not be when terminal currently has corresponding uplink and downlink service data scheduling Mutually conflict.And terminal currently has and can touch according to existing processing method processing mode when corresponding uplink and downlink service data scheduling Send out aperiodicity SRS.

The sending method of the Sounding Reference Signal of the embodiment of the present invention is transmitted in the not scheduled data of terminal, The transmission that SRS can be triggered in real time, enables base station to get the SRS of UE.

Certainly, the SRS of transmission needs to understand specific parameter configuration in advance, and in this embodiment, configuration parameter can prolong It is configured with the relevant parameter in high-level signaling RRC.

And it should be appreciated that function instructions field can be 0~M-bit in the embodiment, be used to indicate the function of the DCI Can, the DCI for allowing non-data to dispatch is other than it can trigger SRS, it may also be used for the triggering of following some new functions.In this feelings Under condition, as long as terminal detection function instructions field is that may know that the function of current DCI.

In addition, in embodiments of the present invention, the Downlink Control Information does not have touching due to not needing to carry out data dispatch Terminal is sent out to send Physical Uplink Shared Channel PUSCH and receive the physical mixed automatic re-transmission indicating channel that base station is sent The function of PHICH.

That is, after terminal receives the Downlink Control Information, it is different from existing process, it will not send corresponding PUSCH would not also trigger corresponding PHICH and receive.

In the sending method of the Sounding Reference Signal of the embodiment of the present invention, when base station judges terminal at this time without downlink Data need to send, while also not receiving terminal application uplink scheduling request, and base station sends one without practical to terminal The corresponding Downlink Control Information of traffic scheduling sends a SRS for triggering terminal.In view of the angle from terminal can not be predicted Whether base station has downlink data to need to send, so the Downlink Control Information DCI for downlink business scheduling cannot be used, but It is used for the down control channel of scheduling of upstream transmissions by sending to terminal, such as can be DCI format 0 or 4.Due to this The DCI of SRS is triggered in embodiment no need to send the scheduling of uplink and downlink actual traffic data, domain field can be used accordingly in DCI In transmission SRS parameter configuration.Certainly, the size of SRS parameter configuration will be consistent with DCI format.

Therefore, on the basis of the above embodiments, triggering terminal is carried in the Downlink Control Information report SRS's SRS parameter configuration.

In this way, terminal do not need to adopt before parameter configuration, but the Downlink Control Information issued according to base station It completes the transmission of SRS, more meets the demand of current base station.

It can recognize through the above, to the function instructions field for the Downlink Control Information being used to indicate, terminal is only Detecting the function instructions field may know that the function of current DCI.In this embodiment, function instructions field indicates triggering terminal When reporting SRS, terminal check be currently for trigger SRS transmission DCI format when, terminal according to the function instructions field just SRS can be sent, then just not having to the meaning for being concerned about corresponding SRS request SRS request field.So the downlink control SRS parameter configuration is carried in the information field of corresponding carrying SRS request in information processed.

Wherein, the SRS parameter configuration includes:

Indicate the terminal single or the information of periodicity sending SRS；Or

It is to be understood that the information in period and subframe used in instruction terminal periodicity sending SRS, corresponds to now Sounding Reference Signal configuration index srs-configIndex in RRC signaling；It indicates that the terminal is sent in SRS to use Repetition factor RPF information, be no longer to be fixed as RPF=2 originally in the case that RPF value is to that should introduce bigger RPF； Indicate that the terminal sends the information of frequency domain initial position used in SRS, e.g. last symbol symbol is still Position DMRS etc. corresponds to after enhancing if SRS can remove the last one OFDM (Orthogonal Frequency Division Multiplexing, orthogonal frequency division multiplexi) character position transmission when；Indicating that the terminal is sent in SRS makes The information of the bandwidth of detection corresponds to the Sounding Reference Signal bandwidth srs-Bandwidth in present RRC signaling； Indicate that the terminal sends the information of frequency domain initial position used in SRS, the position of the frequency domain in corresponding present RRC signaling Set freqDomainPosition；Indicate that the terminal sends the information of orthogonal code used in SRS, OCC code (orthogonal Cover code, orthogonal code), when SRS is when multiple OFDM symbols are sent simultaneously, it is possible to need to introduce OCC.

Following table, by taking DCI format 0 as an example, it is assumed that currently without carrier wave instructions field, TDD UL/DL config.1, CSI Request is 1 bit, and there are the domain request SRS, the payload number of format 0 is 31 bits, Ke Yiru Give a definition the information of DCI format 0:

Information	Bit number
		Function instructions field	0~M
Detect the bandwidth of Sounding	2
		Modulating bandwidth	2
Frequency domain initial position	5
		Duration duration	1
Period and subframe	10
		Time-domain position	1
Cyclic shift Cyclic Shift	3
		RPF	1 or 2, depending on how much needing the RPF factor that indicates
Comb teeth Transmission Comb	1 or 2, depend on RPF
		SRS request	0 or 1 bit, may or may not exist
Antenna port	2
		OCC	1

Certainly, above table is merely illustrative, the presence or absence of information field therein, and sequence and bit number are for more Good interpretation scheme and assume.These can change in practice.But the number of bit used in its DCI need with it is existing Format 0 is consistent.

In conclusion the sending method of the Sounding Reference Signal of the embodiment of the present invention can trigger the hair of SRS in real time It send, in being multiplexed down dispatch information in the case where other instructions field, moreover it is possible to be configured, be compared in real time to the SRS of triggering The dynamic for being conducive to the parameter when DMRS etc. needs the transmitted over resources SRS with other UE multiplexing adjusts, to reach orthogonal mesh 's.

Equally, in LTE system, when terminal needs to carry out reverse link traffic channel transmission, by SR to eNodeB application Uplink scheduling resource.After base station receives the scheduling request of terminal, scheduling authorization can be sent for terminal, by being used for dispatching uplink The DCI 0 or 4 of data transmission dispatches the transmission of PUSCH.Simultaneously when base station has downlink data to be sent to terminal, it will pass through The DCI 0/1A/2B/2C/2D dispatch terminal of dispatching downlink data transmission.

In the embodiment, when base station needs the channel information of terminal to be scheduled or pretreatment operation and and without reality When service data scheduling, a Downlink Control Information can be sent to UE.Functional instructions field is arranged in the Downlink Control Information, for referring to Show that the function of the Downlink Control Information, terminal determine whether that triggering terminal reports SRS according to the information of the function instructions field.Its In, function instructions field can be some bits newly increased, be also possible to the certain bits being multiplexed in existing DCI information field or The instruction that the certain states that can indicate of some information field complete function, for example, reuse the domain SRS request 1bit or 2bit, or reuse the M-bit etc. of resource allocation field.Terminal can carry out the detection of normal control channel on subframe n first, The Downlink Control Information that base station issues is received, and after receiving Downlink Control Information, indicate triggering eventually according to function instructions field End reports SRS, if terminal is transmitted across uplink scheduling request SR in the preset time period before current time, at this point, terminal Also to judge current time whether in the scheduling authorization time window of the SR.The only current time of terminal is not in the scheduling of SR It authorizes in time window, just will not currently there is corresponding uplink and downlink service data scheduling mutually to conflict with terminal.

Can recognize through the above, to be used to indicate be the Downlink Control Information function instructions field, terminal only Detecting the function instructions field may know that the function of current DCI.In this embodiment, function instructions field indicates triggering terminal When reporting SRS, terminal check be currently for trigger SRS transmission DCI format when, terminal according to the function instructions field just SRS can be sent, then just not having to the meaning for being concerned about corresponding SRS request SRS request field.So the downlink control SRS parameter configuration is carried in the information field of corresponding carrying SRS request in information processed.
