Technical field

The present invention relates to coverage enhancement technology, and more particularly relate in a wireless communication environment by repeating to pass It is defeated to strengthen the method for covering performance and network node.

Background technology

With the popularization of various communication network technologies, it is provided to the terminal of more and more species and the branch of equipment communication Hold, such as in addition to common common mobile terminal, also support machine type communication (MTC) equipment.MTC device is one kind by machine The user terminal (UE) that device uses for specific purpose.One example of this MTC device is intelligent electric meter.Some this intelligence Ammeter is placed in basement, and in this case, they undergo serious penetration loss, and therefore it is difficult to and network service.For Solve the problems, such as that this equipment belt comes, some standardization bodies are just laying down technological specification to ensure the communication of this MTC device. Such as have agreed to establish a new work item for this in 3GPP, i.e. " inexpensive MTC UE coverage enhancements " work item.This The target of research in terms of coverage enhancement is to extend the covering of this MTCUE (such as MTC UE of room located underground) 15dB.This UE is referred to as coverage enhancement MTC UE (CE-MTC UE) herein.

In the research process for coverage enhancement, such as the conceptual phase on the problem in 3 gpp, it is understood that weight Multiple transmission is to solve the main method of CE-MTC UE covering problems.The coverage enhancement of 15dB in order to obtain, it is contemplated that will need (physical accidental accesses by PDSCH (physical down link sharing channel)/PUSCH (physical uplink link shared channel) and PRACH Channel) the repetition of tens to hundreds of times transmission, so as to cause being remarkably decreased for spectrum efficiency.It is it is noted that and not all CE-MTC UE are required for the up to coverage extension of 15dB, because for example some CE-MTC UE are likely located at center of housing estate. Therefore treat the CE-MTC UE of center of housing estate are same with the CE-MTC UE of cell edge, i.e., the covering that will carry out 15dB increases Good general causes the substantial amounts of wasting of resources.Therefore in the session discussing of 3GPP RAN1, it has been related to what be can configure using eNB The conclusion of grade of transmission is repeated, wherein can set limited repeats grade of transmission, and corresponds to each grade of transmission that repeats One the number of transmissions.The specific location and/channel condition that allow to according to UE are configured the specific the number of transmissions of UE by this, so that Reduce the waste of resource.

For CE-MTC UE, the method for above-mentioned repetition needs the transmitting procedure for being applied to various data and message, including with Machine accesses (RACH) process.Random access procedure is made of the exchange of following message：

In the lead code (message 1) of uplink transmission

In the random access response (RAR, message 2) of downlink

In the message 3 (Msg3) of uplink

In the message 4 (Msg4, for contention resolved) of downlink

As other data transfers, the transmission of each message involved in RACH also faces huge challenge.In addition, by In determining suitably to retransmit grade or number of retransmissions all without enough information in RACH stages UE and eNB so that problem It is more complicated.For example, the transmission for lead code and RAR, since UE and eNB is most direct there has been no any interaction before Method be make UE and eNB based on itself measurement determine needs number of retransmissions.For Msg3, by eNB based on lead code Measurement indicates that its number of repetition is possible in RAR.And how to be determined for the number of transmissions of Msg4, at present still without special Effective solution.

Illustrative aspect of the invention explained below.More specifically, below with reference to specific non-restrictive example and currently It is considered as the illustrative aspect of the content description present invention of the embodiment being contemplated that of the present invention.It will be appreciated by those skilled in the art that The present invention is never limited to these examples, and can be applied even more extensively.

It will notice that following exemplary description is related generally to by the specification used as non-limiting, exemplary network.Tool For body, related cellular communications networks are used as that coverage enhancement according to the present invention is discussed with LTE (including LTE- is advanced) The exemplary background of technology.Also, the description of illustrative aspect given here and embodiment is more particularly to directly related therewith Term.Such term is only used in the background of the non-restrictive example presented and not limited in any way naturally The present invention.But in fact, disclosed method and apparatus be equally applicable to it is any with similar problems other existing or The communication system of appearance, network deployment in the future, as long as it is compatible with features described herein.

Use below and some alternative describe each aspect of the present invention, embodiment and implementation.It should be noted that according to certain A little to need and constrain, what is be described can alternatively be provided separately or with any combination being contemplated that (also including various standby The combination of the Individual features of choosing) provide.

The embodiment of the present invention provides controls levels of repetition measurement report with the side of effective enhancing covering in a communication network Method.Levels of repetition measurement report is placed under the control of network and eNB by the method, therefore can be according to network environment, property Energy demand and the particular requirement of operator are configured, and are determined whether according to the ability and residing channel circumstance of UE Trigger the transmission of levels of repetition measurement report.Therefore either it is provided which potentially to increase in terms of flexibility or resource efficiency Benefit.In addition, the present invention also provides base station and the equipment that can realize this method at the same time.

The present invention mainly by the Msg4 message in random access procedure by and subsequent other data and signalling exemplified by Solution is discussed, but the program is in other transmission with similar problems and other networks with similar problems Other data and/signalling process is equally applicable.Therefore the present invention is not limited to as exemplary signaling and data transfer Coverage enhancement.

Due to increasing in the description of the embodiment of the present invention using the Msg4 of the RACH random access procedures of LTE system as covering Strong example object, figure 1 illustrates signaling mistake involved in UE performs random access procedure in LTE system first Journey.As shown in Figure 1, it is necessary to which carry out the UE of random access sends RACH lead codes to base station first, the sequence selection of the lead code, Transformat, resource distribution and power requirement for example can in 3GPP technical specifications TS36.211, TS36.212 and TS36.213 To find, due to its for understand the present invention it is not necessary to, details are not described herein.Before if eNB successfully be detected RACH Leading code, in response, it sends RAR message in a given time window to UE.As shown in Fig. 2, the RAR message includes Instruction and uplink grant message (UL Grant) for the Timing Advance of UE.Wherein, the content in uplink grant message It is appointed as in TS36.213：

Frequency hopping indicates：1 bit

Resource block is assigned：10 bits

The modulation blocked and encoding scheme：4 bits

Power control command：3 bits

UL time delays：1 bit

Channel status instruction (CSI) request：1 bit

UE can send Msg3 after receiving RAR message in specified resource, wherein may include RRC connections establishes request Etc. information.As the response to the message, eNB further sends Msg4 to eliminate possible race problem.

It is worth noting that the CSI request bit in uplink license in the technical specification RAR message of current LTE is only Suitable for the RACH processes of non-competing access, it means that for the UE based on contention access, such as MTC UE, this bit is On the shelf.In addition, due to MTC UE business particularity, such as data volume is small, possible bad channel quality etc., Other instructions may also be different from common UE in uplink license, for example, modulation and coding (MCS) scheme instruction may Only need to select suitable MCS from a small number of coded modulation schemes less than 4 bits, in this case, it would be possible to there are other spare time Put or the bit of superfluous She.

According to one embodiment of present invention, one or more in these relaxing qubits be used to indicate whether to UE Need to send levels of repetition measurement report, so that the effectively control levels of repetition measurement in the case where not increasing RAR signaling consumptions Report, strengthens covering performance.

Fig. 3 A are the methods for controlling levels of repetition measurement report used according to an embodiment of the invention in base station end Example flow diagram.As shown in figure 3, the first message from equipment is received first in step 301 base station.In one embodiment In, which is the RACH lead codes during RACH.As previously mentioned, for common UE, the sequence selection of the lead code, Transformat, resource distribution and power requirement can be in such as 3GPP technical specifications TS36.211, TS36.212 and TS36.213 In find.For with covering problem, such as in the very big environment of the propagation losses such as basement UE (such as some electricity Table), the transmission of the RACH lead codes may need to repeat.Due to the difference of the channel condition residing for each UE, its is leading The number of repetition of code can be UE based on oneself measurement it is selected.The measurement can the public reference signal based on cell (CRS) or broadcast channel (such as BCH, SCH) carries out.If the UE of covering problem have selected suitable number of repetition, then May successfully it be detected in step 30l by base station.

After receiving the first message, base station will be known that the form (such as number of repetition), and/or hair of the message Send type, and/or channel condition of UE etc..These information will help base station to determine the need for disappearing second in step 302 Carried in breath and control the equipment to send the instruction of levels of repetition measurement report, and set the value of the instruction.For example, according to one Embodiment, if the detection that base station passes through step 301 finds that RACH lead codes are sent with the form of no repetition, it can be with It is assumed that UE is channel condition good UE or common UE, thus determines to carry not in RAR and control the equipment to send levels of repetition The instruction of measurement report, whereas if base station detects the RACH lead codes of repetition, or lead code number of repetition more than one Determine threshold value, then base station can be assumed that the UE is the UE for needing coverage enhancement, thus need also to make in RAR and follow-up transmission Transmitted with repetition to service the UE.Base station, which can determine to carry in RAR, in this case controls the equipment to send repetition etc. The instruction of level measurement report.Helped in addition, can for example set this to be designated as 1 with triggering UE transmission levels of repetition measurement reports Base station determines the suitable number of repetition that downlink can use.

Fig. 3 B show according to an embodiment of the invention using the RAR message that base station is sent as second message example simultaneously And carry the schematic diagram of levels of repetition measurement report request.In this example, 1 bit in the UL licenses in RAR is used to The instruction of levels of repetition measurement report request is transmitted, and this 1 bit is used as other purposes when not transmitting the instruction.According to this The embodiment of invention, 1 bit are to be used to indicate in UL licenses when not transmitting the instruction of levels of repetition measurement report request Or at least one related information in partly indicating and is following：

L) CSI request；Since the UE for being currently based on contention access does not detect the bit, the ratio in certain embodiments Spy can be reused as the instruction of levels of repetition measurement report request；

2) MCS is indicated；Such as only 3 bit therein is retained be MCS in certain embodiments, and another bit is reused Do the instruction of levels of repetition measurement report request；

3) Power Control indicates；It is assumed that need the UE of coverage enhancement to be sent with maximum power, part in certain embodiments Power Control instruction is used as the instruction of levels of repetition measurement report request；

How RACH transmission that a bit can depending on the type of such as UE or it before is explained.For example, connect After receiving RAR, common UE or the RACH leading UE repeated without transmission UL will be permitted in 1 bit interpretations into CSI request, MCS instructions either Power Control instruction or one part, rather than levels of repetition measurement report request.In another reality Apply in example, base station can also be measured by will carry the RAR of the levels of repetition measurement report request and do not carry the levels of repetition The RAR of report request is sent in different resources, such as is sent using different T/Fs and/or code sequence resources, from And UE is set to be known how to explain the bit of the reuse according to the resource location of detection.According to an embodiment of the invention, can be advance Definition, which is used for transmission the resource group for the RAR for carrying the levels of repetition measurement report request and is used for transmission, does not carry the levels of repetition The resource group of the RAR of measurement report request, two groups of resource non-overlapping copies；Please according to whether carrying the levels of repetition measurement report Ask the transmission for being used for RAR from different resource group selection resources.

Turning now to Fig. 3 A, the carrying or the second message of the levels of repetition measurement report request is not carried in step 303 are sent by base station.The 3rd message from UE is received in step 304 base station afterwards, the 3rd message is for example to be disappeared by second Scheduled in UL licenses in breath.In the step, base station is based at least partially on whether it carries repetition in second message Level measurement report request indicates and/or the value of the instruction, to detect the 3rd message.According to one embodiment, if base station The instruction of levels of repetition measurement report request is carried in second message, and the instruction is arranged to triggering and (such as is set to " 1 ") when sending levels of repetition measurement report, then base station will detect levels of repetition measurement from the 3rd message of reception for the equipment Report；It is on the contrary, it is assumed that levels of repetition measurement report is not present in the 3rd message.It is included in being somebody's turn to do in the 3rd received message Levels of repetition measurement report is indicated on can be used for Msg4 and/or the repetition time of other downlink transfers estimated by UE to base station The information of number or levels of repetition.According to an embodiment of the invention, which can for example indicate following each At least one of in：

1) successfully detect described second to disappear, cease the minimum number of repetition of the second message used；The numerical value can be small The actual numbers repeated of RAR are sent in base station；Such as base station have selected levels of repetition 3 for RAR, such as corresponding to 100 times Repeat to transmit, but RAR be successfully decoded if UE is using 50 times of the RAR of reception transmission, UE can report 50 times without It is 100 numbers of repetition.

2) on the 4th message number of repetition estimation；UE can make successfully detection RAR in this case Minimum transfer number is converted to the estimation of the required number of repetition of transmission to the 4th message (such as Msg4)；This is estimated Evaluation, which can be differently configured from, successfully detects minimum transfer number used in RAR, because UE is considered that the transmission of the 4th message The MCS different from the second information may be used, and/or may allow the factors such as HARQ re-transmissions in view of the 4th message.At one In embodiment, UE can be by the signal-to-noise ratio of the downlink detected compared with a certain reference signal-to-noise ratio, so that it is determined that to report The number of repetition for the 4th message.For example, when RAR number of repetition i are transmitted, then this is to repeat with reference to signal-to-noise ratio settings Number i transmits the 4th required lowest signal-to-noise of message, therefore when the signal-to-noise ratio that UE is measured is less than the signal-to-noise ratio, UE can To report a number of repetition higher than number of repetition i；For example, the number of repetition of this report can be the signal-to-noise ratio and ginseng of measurement Examine the function of the difference of signal-to-noise ratio.

3) on the 4th message levels of repetition estimation；UE does not send the number of retransmissions of estimation in this case And only send its corresponding levels of repetition；This feedback will help to save signaling, because the number of possible grade is much smaller than can The number of the number of energy.

4) number of repetition on the 4th message is relative to the number of repetition used in the transmission of the second message The estimation of zoom factor, wherein the zoom factor is selected from predetermined multiple zoom factors；If for example, RAR weights Again number is 100 times and UE is only just successfully decoded with the transmission of 50 times, then UE can report zoom factor a=0.5, i.e., the 4th disappears Breath can repeat 0.5x100=50 times.In order to save feedback signaling, limited zoom factor, such as A=can be defined [0.250.50.751], then UE only needs to select suitable zoom factor during 2 bits are possible from 4 in this case.

5) instruction of the sub- grade selected in the levels of repetition used in the transmission from the second message, wherein described son etc. Level is selected from more predetermined sub- grades, and each sub- grade in the multiple sub- grade corresponds to a weight Again count；In such a case, it is possible to transmitted for the definition of each RAR levels of repetition for the 4th message and/or follow-up other Sub- grade so that UE can more accurately feed back suitable number of repetition.Such as RAR levels of repetition 3 (for example, right Should be in repetition 100 times), it is as follows that sub- grade can be defined：3-l：25 times；3-2：50 times；3-3：75 times；3-4：100 times.UE according to The reception condition of RAR reports sub- grade, its effect is equal to the feedback of zoom factor form as described above.

6) difference on the number of repetition used in the number of repetition of the 4th message and the transmission of the second message Estimation；Relative to absolute number of repetition, in certain embodiments, UE can also report difference, for the 4th message and/or The number of repetition and the difference of RAR number of retransmissions of other follow-up transmission.

After the 3rd message, base station determines the transformat of the 4th message in step 305 and is sent out in step 306 to UE Send the 4th message.

According to one embodiment, if base station detects levels of repetition measurement report in the 3rd message, at least partly Ground determines the iterative transfer times and/or levels of repetition of the 4th message according to this report, furthermore it is also possible to determine such as MCS.Such as Fruit base station does not detect levels of repetition measurement report in the 3rd message, then is based at least partially on to the first message And/or the 3rd message measurement determine the 4th message iterative transfer times and/or levels of repetition.In one embodiment In, further include definite MCS.

It should be noted that base station can only by the levels of repetition measurement report in the 3rd message as reference, at the same time Consider that other factors finally determine the transformat (number of repetition, MCS etc.) of the 4th message.In one embodiment, base station can To use the 4th message the number of repetition for being different from UE and being reported.Fig. 3 C show exemplary signaling diagram as one.At this In example, UE sends the RACH lead codes that levels of repetition is 3 to eNB.Based on the preamble detection, eNB is using levels of repetition as 3 RAR in response, and indicates UE report levels of repetition measurement reports in RAR.Assume UE with corresponding to weight in this example RAR has been successfully decoded in the number of repetition of multiple grade 2, and therefore reports levels of repetition 2 as use to eNB in the 3rd message In the 4th message and/or thereafter the levels of repetition of other transmission.In this example, after the report for receiving UE, base station is not The levels of repetition 2 of UE reports is used for the transmission of the 4th message, repetition that still use can be same with the transmission of RAR on the contrary etc. Level 3.This be probably in view of the variation characteristic of channel or scheduled different resources, used different MCS etc. because The decision that element is made.In contrast in the example of Fig. 3 D, the levels of repetition that base station employs UE reports is used for the 4th message Transmission.

According to one embodiment of present invention, the definite levels of repetition for the 4th message can be also applied to by base station Hereafter other data and/or signalling.

According to still another embodiment of the invention, after the 4th message is sent, base station can send another message, and Bits by the way that one or more reservation in another message to be done to other instructions are used as asking the equipment to send or more The instruction of the new levels of repetition measurement report.According to an embodiment of the invention, another message can be with DCI format 0 UL grant messages.According to another embodiment of the present invention, the bit that other instructions are done in one or more of reservations includes In UL grant messages it is following at least one of：

A) it is used for the bit of channel quality instruction；

B) it is used for the bit of Power Control；
