Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of method and base station that subscriber equipment sends measuring reference signals of triggering.
Background technology
Long Term Evolution (Long Term Evolution at 3GPP, hereinafter to be referred as " LTE ") in technology, subscriber equipment (User Equipment, hereinafter to be referred as " UE ") need to be to base station (E-UTRAN NodeB, hereinafter to be referred as " eNB ") transmission measurement reference signal (Sounding Reference Signal, hereinafter to be referred as " SRS "), with helping eNB, obtain uplink channel information, thereby realize the functions such as frequency selective scheduling and link circuit self-adapting.UE comprises to the process of eNB transmitting SRS: eNB notifies UE configuration SRS to send parameter by high-level signaling in advance, such as SRS sends the cycle, should in which frequency range, send SRS, use which broach, which cyclic shift (CS, cyclic shift), adopt which kind of frequency-hopping mode etc.; Afterwards, the antenna port that UE just periodically adopts by it reports eNB by SRS.
Upgraded version Long Term Evolution enhancing (Long Term Evolution Advanced, hereinafter to be referred as " LTE-A ") technology of LTE agreement has been proposed at present.A difference of LTE technology and LTE-A technology is, in LTE technology, UE only supports single-antenna transmission in uplink, and like this, UE can only send SRS by an antenna port; And in LTE-A technology, UE supports many antenna transmissions in uplink, UE sends respectively SRS by a plurality of antenna ports of its support.
In order to realize the uplink SRS of UE, send, reserved certain running time-frequency resource in community, in LTE technology, for a UE, need to be periodically the reserved running time-frequency resource of an antenna port of this UE in advance.And in LTE-A technology, if still adopt UE in LTE technology periodically to report the way of SRS to eNB, need to be for a UE, a plurality of antenna ports that are periodically this UE are reserved respectively running time-frequency resource, like this, can greatly increase the taking of running time-frequency resource, thereby cause the shortage of resources in system.
In order to solve the problem of running time-frequency resource shortage, for LTE-A technology, dynamic aperiodic of SRS scheme has been proposed at present, that is to say, UE does not need periodically to eNB, to send SRS, but determined whether to obtain SRS by eNB, when needs obtain, trigger UE and send SRS, UE is only after being triggered, just can to eNB, send SRS by each antenna port, owing to periodically sending SRS without UE, therefore, without each antenna port that is periodically UE, reserve respectively running time-frequency resource, thereby reduced taking running time-frequency resource.
In LTE-A technology, although proposed to adopt dynamic aperiodic SRS scheme,, a kind of idea has just been proposed at present, be not given under dynamic aperiodic of mode, how to trigger the concrete solution that UE sends SRS.

Embodiment
For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Below in conjunction with the drawings and specific embodiments, further illustrate the technical scheme of the embodiment of the present invention.
In dynamic aperiodic SRS scheme, eNB determines that while need to obtain SRS, just can trigger UE sends SRS, and the situation that conventionally need to obtain SRS is to have upstream data to need transmission.Before needs transmit ascending data, eNB can trigger UE by up transmission indication (UL grant) signaling and send upstream data.Therefore, can consider to utilize this UL grant signaling to trigger SRS sends.
In LTE-A technology, in fact the frequency-hopping mode of considering UE can be fixed, such as being fixed as, adopt frequency hopping always, or be fixed as cancellation frequency hopping, so just without existing frequency hopping indicating bit in UL grant signaling, indicate UE whether to adopt frequency hopping, like this, in UL grant signaling, existing frequency hopping indicating bit can be released for triggering the SRS transmission of UE.Therefore, the embodiment of the present invention has proposed a kind of method that subscriber equipment sends measuring reference signals that triggers, as shown in Figure 1, can comprise: step 101, when the state for UE configuration is the first state of corresponding frequency hopping fixed form, by this first state configuration to UE; Step 102, utilize frequency hopping indicating bit in UL grant signaling to trigger UE to send measuring reference signals SRS.Wherein, frequency hopping fixed form is that UE is configured under which: be fixed as employing frequency hopping, or be fixed as cancellation frequency hopping, do not adopt frequency hopping.Answer in contrast, frequency hopping indicating mode is: the mode that determines whether to adopt frequency hopping by indication.
In LTE-A technology, the mode that UE sends SRS may comprise: be with SRS in outer SRS and band.Wherein, be with frequency band that outer SRS refers to transmitting SRS outside the frequency band of transmit ascending data, that is to say, upstream data and SRS do not share running time-frequency resource; Band in SRS refer to transmitting SRS frequency band within the frequency band of transmit ascending data, that is to say, upstream data and SRS share running time-frequency resource.Along with the development of LTE-A technology, may there are following two kinds of business scenarios:
Business scenario one, UE be the outer SRS of tenaculum and the interior SRS of band simultaneously.
A side in business scenario two, the outer SRS of a UE tenaculum and band in SRS.
Like this, based on the invention described above embodiment method, in concrete business realizing process, the embodiment of the present invention can provide detailed triggering UE to send the solution of SRS for above-mentioned two kinds of business scenarios respectively.For above-mentioned business scenario one and business scenario two, lifting respectively specific embodiment is below described.
Embodiment mono-:
The corresponding business scenario one of this embodiment mono-, UE is the outer SRS of tenaculum and the interior SRS of band simultaneously.In order realizing, to trigger UE transmission SRS, in this embodiment mono-, to increase in advance a bit information position in UL grant signaling newly, whether this added bits information bit is defined as the outer SRS of index strip and is triggered.
In this embodiment mono-, need to pre-define two kinds of UE states.
In actual business realizing, whether UE adopts frequency-hopping mode to be fixed, thereby discharge the frequency hopping indicating bit (this kind of situation is called frequency hopping fixed form) in UL grant signaling, certainly whether frequency hopping can not be fixed UE yet, according to existing frequency hopping indicating bit in UL grant signaling, dynamically indicates (this kind of situation is called frequency hopping indicating mode).Therefore, for frequency hopping fixed form and frequency hopping indicating mode, just can be respectively UE definition two states.Two kinds of UE states can be defined as: state 1 (corresponding frequency hopping fixed form), UE can be triggered and send the outer SRS of band, also can be triggered and send SRS in band; State 2 (corresponding frequency hopping indicating mode), UE send the outer SRS of band only to be triggered.
Referring to Fig. 2, the process that triggers UE transmission SRS in the embodiment of the present invention one can comprise the steps:
Step 201: for a UE (being designated as UE1), eNB judges the current applicable configuration status 1 of this UE1 or state 2, if 1 execution step 202 of state, if 2 execution steps 205 of state.
Here, can judge that UE1 is applicable to the state of configuration according to the mobile status of default or UE1.
When judging according to the mobile status of UE1, because eNB can be according to the reference signal receiving (Reference Signal in the prior art, hereinafter to be referred as " RS ") obtain channel status, therefore, in the present embodiment one, can utilize this feature, eNB receives after the RS reference signal that UE1 sends in different subframes, can obtain the channel status at different subframe UE1 respectively, thereby draw the variation of the channel status of UE1, if this changes greatly, such as changing value has surpassed predefined threshold value, so, illustrate that UE1 is in high speed mobile status, such as the user of UE1 is on the automobile of a high-speed cruising, if change little, such as changing value is lower than predefined threshold value, so, illustrate that UE1 is in low speed mobile status, such as the user of UE1 is indoor or in walking state.
If eNB detects UE1 in low speed mobile status, so, UE1 can adopt frequency hopping fixed form, and eNB just can judge the state 1 that UE1 is applicable to the corresponding frequency hopping fixed form of configuration; If eNB detects UE1 in high speed mobile status, so, UE1 is applicable to adopting frequency hopping indicating mode, and eNB just can judge the state 2 that UE1 is applicable to the corresponding frequency hopping indicating mode of configuration.
Step 202:eNB by the information of employing state 1, frequency hopping fixed form information configuration to UE1.
Step 203: when trigger timing arrives, whether whether eNB is triggered with the outer SRS of bit information position index strip of 1bit newly-increased in UL grant signaling, and be triggered with SRS in existing frequency hopping indicating bit index strip in UL grant signaling.
Step 204:eNB sends to UE1 by the UL grant signaling when front construction, finishes current flow process.
After this, UE1 receives after UL grant signaling, according to the bit information position of 1bit newly-increased in this signaling and frequency hopping indicating bit, just can determine that the transmission of SRS is adopt the outer SRS of band to send or adopt SRS in band to send.
Step 205:eNB by the information of employing state 2, frequency hopping indicating mode information configuration to UE1.
Step 206: when trigger timing arrives, whether eNB is triggered with the outer SRS of bit information position index strip of 1bit newly-increased in UL grant signaling, and utilizes the frequency hopping indicating bit in UL grant signaling to indicate whether to adopt frequency hopping.
While carrying out this step, UE1 adopts frequency hopping indicating mode, because can only being triggered, UE1 is with outer SRS, therefore, only need the bit information position that increases a new 1bit to indicate, and without other existing indicating bits of changing UL grant signaling, that is to say, whether the effect of frequency hopping indicating bit adopts frequency hopping with identical being still used to indicate in prior art.
Step 207:eNB sends to UE1 by the UL grant signaling when front construction.
After this, UE1 receives after UL grant signaling, just can determine whether to trigger adopting the outer SRS of band to send SRS according to the bit information position of the 1bit newly adding in this signaling.
In above-mentioned steps 202 and step 205, eNB can be by high-level signaling such as Radio Resource control (RRC, Radio Resource Control) signaling completes layoutprocedure.
In embodiments of the present invention, when triggering UE transmission SRS can be same as the prior art, like this, in above-mentioned steps 203 and step 206, the situation that trigger timing arrives can be just prior art, and situation about arriving such as this trigger timing can be exemplified as: eNB detects UE1 has upstream data to need transmission.
According to above-mentioned Fig. 2 flow process, can obtain, in the embodiment of the present invention one, provided and utilized UL grant signaling to trigger as triggering signaling the process that UE sends SRS, wherein, no matter UE configuration is state 1 or state 2, in UL grant signaling, all only need to increase the bit information position of a bit, reduced the expense to control signal, whether the bit information position of the 1bit of this increase always outer SRS of index strip is triggered.In addition, existing frequency hopping indicating bit, in 1 time index strip of state, whether SRS is triggered, and indicates whether to adopt frequency hopping 2 times at state.
Embodiment bis-:
The corresponding business scenario one of this embodiment bis-, UE is the outer SRS of tenaculum and the interior SRS of band simultaneously.In order to realize, trigger UE transmission SRS, in this embodiment bis-, a newly-increased bit information position in UL grant signaling, is with embodiment mono-difference in advance, and in embodiment bis-, whether this added bits information bit is defined as SRS in index strip and is triggered.
In the present embodiment two, need to pre-define two kinds of UE states.
For frequency hopping fixed form and frequency hopping indicating mode, be respectively UE and defined two states: state a (corresponding frequency hopping fixed form), UE can be triggered and send the outer SRS of band, also can be triggered and send the interior SRS of band; State b (corresponding frequency hopping indicating mode), UE send SRS in band only to be triggered.
Referring to Fig. 3, the process that triggers UE transmission SRS in the embodiment of the present invention two can comprise the steps:
Step 301: for a UE (being designated as UE1), eNB judges that this UE1 is applicable to configuration status a or state b, if state a performs step 302, if state b performs step 305.
The determination methods of this step can be identical with the determination methods of step 201 in embodiment mono-.Such as, when judging according to the mobile status of UE1, if eNB detects UE1 in low speed mobile status, so, eNB just can judge the state a that UE1 is applicable to the corresponding frequency hopping fixed form of configuration; If eNB detects UE1 in high speed mobile status, so, eNB just can judge the state b that UE1 is applicable to the corresponding frequency hopping indicating mode of configuration.
Step 302:eNB will adopt the information, frequency hopping fixed form information configuration of state a to UE1.
Step 303: when trigger timing arrives, whether eNB is triggered with SRS in the bit information position index strip of 1bit newly-increased in UL grant signaling, and whether be triggered with the outer SRS of existing frequency hopping indicating bit index strip in UL grant signaling.
Step 304:eNB sends to UE1 by the UL grant signaling when front construction, finishes current flow process.
After this, UE1 receives after UL grant signaling, according to the bit information position of 1bit newly-increased in this signaling and frequency hopping indicating bit, just can determine that the transmission of SRS is adopt the outer SRS of band to send or adopt SRS in band to send.
Step 305:eNB will adopt the information, frequency hopping indicating mode information configuration of state b to UE1.
Step 306: when trigger timing arrives, whether eNB is triggered with SRS in the bit information position index strip of 1bit newly-increased in UL grant signaling, and utilizes the frequency hopping indicating bit in UL grant signaling to indicate whether to adopt frequency hopping.
Step 307:eNB sends to UE1 by the UL grant signaling when front construction.
After this, UE1 receives after UL grant signaling, just can determine whether to trigger adopting SRS in band to send SRS according to the bit information position of the 1bit newly adding in this signaling.
In above-mentioned steps 302 and step 306, eNB can be by high-level signaling such as RRC signaling completes layoutprocedure.
In the present embodiment two, the situation that trigger timing arrives is identical with the situation that trigger timing in embodiment mono-arrives.
According to above-mentioned Fig. 3 flow process, can obtain, in the present embodiment two, provided and utilized UL grant signaling to trigger as triggering signaling the process that UE sends SRS, wherein, no matter that UE configuration is state a or state b, in UL grant signaling, all only need to increase the bit information position of a bit, reduced the expense to control signal, whether the bit information position of the 1bit of this increase always interior SRS of index strip is triggered.In addition, existing frequency hopping indicating bit under state a outside index strip SRS whether be triggered, and indicate whether to adopt frequency hopping under state b.
Embodiment tri-:
The corresponding business scenario two of this embodiment tri-, in the outer SRS of UE tenaculum and band in SRS one, for ease of describing, the SRS of take in the present embodiment three outside UE tenaculum describes as example.Be with the maximum difference of embodiment mono-, two, in embodiment tri-, without added bits information bit in UL grant signaling.
The present embodiment three need to pre-define two kinds of UE states: state A (corresponding frequency hopping fixed form), UE can be triggered and send the outer SRS of band; State B (corresponding frequency hopping indicating mode), UE cannot be triggered and send the outer SRS of band.
Referring to Fig. 4, the process that triggers UE transmission SRS in the embodiment of the present invention three can comprise the steps:
Step 401: for a UE (being designated as UE1), eNB judges that this UE1 is applicable to configuration status A or state B, if state A performs step 402, if state B performs step 405.
The determination methods of this step can be identical with the determination methods of step 201 in embodiment mono-.Such as, when judging according to the mobile status of UE1, if eNB detects UE1 in low speed mobile status, so, eNB just can judge the state A that UE1 is applicable to the corresponding frequency hopping fixed form of configuration; If eNB detects UE1 in high speed mobile status, so, eNB just can judge the state B that UE1 is applicable to the corresponding frequency hopping indicating mode of configuration.
Step 402:eNB will adopt the information, frequency hopping fixed form information configuration of state A to UE1.
Step 403: when trigger timing arrives, whether eNB is triggered with the outer SRS of existing frequency hopping indicating bit index strip in UL grant signaling.
Step 404:eNB sends to UE1 by the UL grant signaling when front construction, finishes current flow process.
After this, UE1 receives after UL grant signaling, just can determine whether to trigger adopting the outer SRS of band to send SRS according to the frequency hopping indicating bit in this signaling.
Step 405:eNB will adopt the information, frequency hopping indicating mode information configuration of state B to UE1.
Step 406: when trigger timing arrives, eNB only constructs UL grant signaling for the triggering of upstream data.
In the situation that UE1 is configured to state B, the use of the frequency hopping indicating bit in UL grant signaling is same as the prior art, still indicates whether to adopt frequency hopping, and like this, in fact the UL grant signaling of structure is not carried out SRS transmission for triggering UE1.
Step 407:eNB sends to UE1 by the UL grant signaling when front construction.
After this, UE1 receives after UL grant signaling, does not trigger the transmission of SRS.
In above-mentioned steps 402 and step 405, eNB can be by high-level signaling such as RRC signaling completes layoutprocedure.
In the present embodiment three, the situation that trigger timing arrives is identical with the situation that trigger timing in embodiment mono-arrives.
According to above-mentioned Fig. 4 flow process, can obtain, in the present embodiment three, provided and utilized UL grant signaling to trigger as triggering signaling the process that UE sends SRS, wherein, no matter that UE configuration is state A or state B, in UL grant signaling, all without increasing new bit information position, reduced the expense to control signal.In addition, existing frequency hopping indicating bit, under state A, outside index strip, whether SRS is triggered, and indicates whether to adopt frequency hopping under state B.
In above-described embodiment three, be to take the outer SRS of UE1 tenaculum to describe as example, in other embodiments of the invention, if SRS in UE1 tenaculum, so, only the outer SRS of band in the corresponding description of above-mentioned Fig. 4 flow process need be replaced with to SRS in band, other implementation procedures are identical.
It should be noted that, in each embodiment described above, all by eNB judgement UE, to be applicable to the state of configuration, in other embodiments of the invention, also can according to default etc., according to judgement UE, be applicable to by other management equipments the state of configuration, and notifying eNB by judged result, eNB directly carries out correspondingly subsequent treatment according to the judged result obtaining.
