Description

Method and apparatus for the transmission of bandwidth limited devices

Technical field

The present invention relates to the transmission of bandwidth limited devices in cordless communication network, the method and apparatus being specifically related to transmission for realizing bandwidth limited devices.

Background technology

Machine type communication (MTC) equipment is a kind of is the user terminal (UE) that specific purpose uses by machine. At third generation partner program (3GPP), in the process formulating Long Term Evolution (LTE) version 12 (LTERel-12), working group (WI) about low complex degree MTC (LC-MTC) is over, and will decline nearly 50% according to the complexity (cost) of its result of study MTCUE. In the version 13 of LTE, reach an agreement on and set up another working group, be devoted to the complexity/cost reducing MTC further and the covering of enhancing MTC, and improve the power consumption of MTCUE. A kind of technology reducing complexity is that radio frequency (RF) bandwidth of LC-MTCUE is contracted to 1.4MHz (utilizing 6 Physical Resource Block (PRB) to be operated). In nearest 3GPPRAN1 meeting (3GPPRAN1#78bis), in all complexity reduction technology, bandwidth reduces and is given the highest priority. Therefore, in this article, by discussing as the example of Bandwidth-Constrained UE using this operation at the LC-MTCUE of 1.4MHz, it should be noted, however, that method and apparatus disclosed in this specification is equally applicable to other bandwidth limited devices.

For Bandwidth-Constrained UE, it may be desirable to it can operate in the communication system of any bandwidth, and coexist within the system with normal UE. It is also expected to this Bandwidth-Constrained UE can adjust its operating frequency such that it is able to any narrower subband in bigger system bandwidth works allow the multiplexing between Bandwidth-Constrained UE and and normal UE between multiplexing.

In current LTE system, UE is receiving from needing feedback positive acknowledgment (ACK) or Negative Acknowledgement (NACK) after the downlink data of base station, transmission in this feedback Uplink Control Channel physically (PUCCH). According to current LTE standard, it is positioned at the two ends of system bandwidth for PUCCH resource, as shown in Figure 1. In order to obtain frequency diversity gain, in single PUCCH transmits, performing frequency hopping in units of time slot, wherein the transmission of the PUCCH in a subframe is divided into two time slots and the resource of the different ends of each Time Slot Occupancy system bandwidth, as shown in Figure 1. Resource for PUCCH is used to send the instruction (possibly also with certain skew) that the resource index of the control channel (such as, the physical downlink control channel EPDCCH of physical downlink control channel PDCCH or enhancing) of down link data schedule information implies. For the bandwidth limited devices of such as LC-MTCUE, current this frequency hopping operation is very challenging property. Because the frequency hopping performed between the two ends of system bandwidth will cause that UE transmits the change of subband, reset thus needing UE end to perform frequency, and frequency will make normal transmission cannot be carried out during resetting. If base station still is received receiving the decline with demodulation performance by causing according to normal transmission. Another kind of directly solution is frequency hopping to be limited in the narrower bandwidth of operation of bandwidth limited devices, as in figure 2 it is shown, but its result is difficult to obtain any significant diversity gain. Moreover, the program also brings other problems, for instance, which occupies the transfer resource for physical uplink link shared channels (PUSCH), this PUSCH transmission is generally only useful in frequency continuous print PRB block; It addition, when distributing to the subband overlap of two UE, as in figure 2 it is shown, then the PRB at edge is distributed to PUCCH in a subband wherein, by no longer continuous for the surplus resources caused in another subband, available PUSCH continuous resource can be reduced. In addition, another problem to solve is how to notify its available resource of bandwidth limited devices and the resource transmitted for each PUCCH.

Therefore, how to enable the equipment of Bandwidth-Constrained is benefited from diversity gain, and avoid the problems referred to above is the technical issues that need to address simultaneously.

Specifically, the present invention and embodiment mainly describe the 3GPP technical specification as non-limiting example. Especially, LTE/LTE-A communication system is taken as applying the example of the non-limiting communication system of exemplary embodiment described herein herein. Therefore, the description of exemplary embodiment given herein is referring especially to the term in LTE/LTE-A. These terms only use in the context of non-limiting example presented herein, therefore do not limit the invention to this. On the contrary, any other network configuration and system deployment all can use, as long as it is compatible with feature mentioned in this article.

Hereinafter, various embodiments of the present invention and enforcement aspect will be described by some alternative methods. To understand, according to certain demand and restriction, all these replacement schemes can individually provide or provide with any possible combination.

Referring now to Fig. 4 a, it is according to an embodiment of the invention at the flow chart of the exemplary method of the equipment end of Bandwidth-Constrained. As shown in fig. 4 a, the method comprising the steps of S401, control information is received for the base station from described cordless communication network, the instruction of described control information is at least two resource area of described transmission of described bandwidth limited devices, and wherein said at least two resource area is in the subband that at least two of the system bandwidth of described base station is different; Step S402, for determining in indicated described at least two resource area the resource for described transmission; And step S403, it being used for utilizing determined resource to perform described transmission, wherein said transmission uses the resource in a resource area in described at least two resource area in same subframe.

According to one embodiment of present invention, in step S401, this control information can control (RRC) signaling by radio resource and receive. This control information directly can explicitly indicate this at least two resource area, or indicates one of them resource area, and by configuring or predetermined side-play amount knows other resource area.

According to one embodiment of present invention, the system bandwidth of base station is divided into some subbands in advance, for instance each subband is not more than the bandwidth of operation of this bandwidth limited devices. These subbands can non-overlapping or partly overlap. In one embodiment of the invention, this at least two resource area of control information instruction lays respectively at different subbands. According to another embodiment of the present invention, a part of region in this at least two resource area is positioned at a subband, and another part region is positioned at another subband. Certain interval is there is in these two subbands in frequency.

According to one embodiment of present invention, each resource area in this at least two resource area indicated by control information is less than the size of the subband of system definition; And in another embodiment of the invention, each resource area can equal to or more than the subband size of system definition.

According to one embodiment of present invention, it is PUCCH transmission by using the transmission that carries out of this at least two resource area.

According to one embodiment of present invention, in step S402, it is determined that the resource being used for transmitting in indicated at least two resource area includes the described resource determined for performing described transmission in described subframe based on the index of subframe. Such as, bandwidth limited devices can determine the PUCCH subframe for feeding back according to the subframe of the predetermined time relationship between downlink transmission and PUCCH feedback and receiving downlink data, may then based on the index of this PUCCH subframe and impliedly obtains for this PUCCH resource area transmitted. According to one embodiment of present invention, the index of this PUCCH subframe can be the absolute indices of this subframe, for instance the subframe numbers (SFN) in LTE. According to another embodiment of the present invention, the index of this PUCCH subframe can be this subframe index relative to certain given subframe, for instance, it is this subframe relative deviant of transmitting the subframe of PUCCH relative to this equipment first.

According to another embodiment of the present invention, in step S402, determine that the resource for described transmission impliedly determined in the index included according to the resource used from the control channel (such as, the physical downlink control channel EPDCCH of physical downlink control channel PDCCH or enhancing) of described base station for the resource transmitted in indicated at least two resource area. Such as, according to an embodiment of the invention for the schematic diagram of the resource of PUCCH transmission shown in Fig. 4 c. In this example it is assumed that the control information received in step S401 indicates two PUCCH resource regions in Fig. 4 c. Noting, these two resource area are not necessarily intended to the edge being in same band to obtain frequency diversity gain, if sufficiently large at these two interregional intervals. As it can be seen, when PUCCH transmits in a subframe, there is not frequency hopping on the border of two time slots, this is different from the operation in current LTE. And for the sake of simplicity, this PUCCH transmission takies same PRB in subframe. In this example it is assumed that each PUCCH resource region includes two PRB, thus for the total 4PRB of resource of PUCCH. According to current system configuration, each PUCCHPRB can support the transmission of 12 PUCCH, wherein these 12 PUCCH mode multiplexing by CDMA. Therefore these 4 PRB will provide for 48 PUCCH resource. Assuming that the PUCCH resource in two PUCCH resource regions is indexed as follows together continuously:

PUCCHPRB#1={1,5,9,13,17,21,25,29,33,37,41,45}

PUCCHPRB#2={2,6,10,14,18,22,26,30,34,38,42,46}

PUCCHPRB#3={3,7,11,15,19,23,27,31,35,39,43,47}

PUCCHPRB#4={4,8,12,16,20,24,28,32,36,40,44,48}

That is, a PUCCHPRB includes index for the { PUCCH resource of 1,5,9,13,17,21,25,29,33,37,41,45}. Assuming that according to given mapping relations, in downlink, the resource index (first index controlling Resource Unit CCE that such as this EPDCCH uses) for using to the EPDCCH of this equipment transmission downlink scheduling message implicitly points to PUCCH index 7, then, may determine that according to index above, this PUCCH is positioned at the 3rd PRB, belongs to the second PUCCH resource region. Thus, this equipment can determine the resource for PUCCH transmission.

According to another embodiment of the present invention, can be used for the resource of EPDCCH and include more than one subband, and in step S402, determine and include determining the subband being arranged to EPDCCH for the resource transmitted in indicated at least two resource area, determine in this at least two PUCCH resource region for the PUCCH resource area transmitted according to for the mapping relations between subband (that is, the subband that transmission EPDCCH uses) and the described at least two PUCCH resource region of EPDCCH; And the index according to the resource used of the EPDCCH from described base station is impliedly determined in determined resource area for this PUCCH resource transmitted further. Such as, two PUCCH resource regions that the control information received in step S401 indicates in Fig. 4 c are still assumed that. In this example, as an example embodiment that two EPDCCH subbands for this device definition, i.e. EPDCCH subband 1 and EPDCCH subband 2. According to one embodiment of present invention, base station can use EPDCCH subband 1 at each odd numbered sub-frames, and uses EPDCCH subband 2 to be transmitted obtaining classification gain at even subframe. In this example it is assumed that the PUCCH resource in two PUCCH resource regions is indexed as follows respectively:

PUCCH resource region 1:

PUCCHPRB#1={1,3,5,7,9,11,13,15,17,19,21,23}

PUCCHPRB#2={2,4,6,8,10,12,14,16,18,20,22,24}

PUCCH resource region 2:

PUCCHPRB#3={1,3,5,7,9,11,13,15,17,19,21,23}

PUCCHPRB#4={2,4,6,8,10,12,14,16,18,20,22,24}

According to one embodiment of present invention, the PUCCH resource region being used for PUCCH transmission is depended on that base station sends the subband of the used EPDCCH of downlink schedule information. In this example, assuming that at the subband for EPDCCH (namely, the transmission subband that uses of EPDCCH) and two PUCCH resource regions between there are 1 mapping relations to 1, such as, if employing EPDCCH subband 1, then use PUCCH resource region 1 is transmitted by corresponding PUCCH; And if employed EPDCCH subband 2, then use PUCCH resource region 2 would be transmitted by corresponding PUCCH. Assuming that base station uses EPDCCH subband 1 to have sent PDSCH scheduling grant, and this EPDCCH resource implicitly points to PUCCH index 9, then this equipment is it was determined that the resource for PUCCH transmission is the PUCCH resource 9 in PUCCH resource region 1.

According to another embodiment of the present invention, this equipment is configured for multiple control channel set, for instance multiple EPDCCH gather, and will detect descending scheduling license in the search volume of the plurality of EPDCCH. In this embodiment, in step S402, determining and include for the resource transmitted in indicated at least two resource area, the control channel set (such as EPDCCH set) used based on the control channel (such as EPDCCH) of the such as schedule information of the carrying from described base station determines the resource area for described transmission in indicated described at least two resource area. In one embodiment, exist between EPDDCH set and multiple PUCCH resource region with on the similar mapping relations of an embodiment, thus this equipment can determine at least two resource area the resource for transmitting according to similar method.

If the uplink control information entrained by PUCCH (UCI) completes transmission in a single sub-frame, then the effect of diversity gain is embodied in, and for the transmission of multiple UCI message, can obtain good average behavior. Because some UCI transmits in a subband, other UCI transmit in other subbands, if multiple UCI are relevant to single downstream data packet (such as, each UCI message includes the different HARQ feedback retransmitted for same packet), then the feedback for this packet is obtained in that diversity gain as entirety. In another example, if UCI message includes channel condition information (CSI) feedback, then using CSI feedback as entirety, it is possible to obtain diversity gain.

According to one embodiment of present invention, the transmission of step S403 is more than one (such as N > 1) subframe completes, and wherein determine at least two resource area indicated by control information in step S401 and include for the resource transmitted: the number (value of such as N) based on this more than one subframe determines the described resource for described transmission. Exemplarily, this transmission can be the PUCCH transmission of Bearer Channel status information (CSI). Assuming that this CSI information is at N > it is transmitted in 1 subframe. Then exemplarily, this front N/2 subframe can use the PUCCH resource in i-th PUCCH resource region to be transmitted, and the resource of the jth resource area in this at least two resource area can be used in rear N/2 subframe to be transmitted, wherein j is different from i. According to embodiments of the invention, this different resource area i and j is arranged in the different sub-band with certain frequency interval of system bandwidth, thereby through this transmission means, is obtained in that diversity gain in the transmission of this CSI information.

According to one embodiment of present invention, the transmission of step S403 is more than one (such as N > 1) subframe completes, and perform to repeat transmission in the plurality of subframe, in this case, the resource for this transmission can be determined based on number of repetition according to embodiments of the invention. An example is provided referring to Fig. 4 c-4d. Assuming that the PUCCH resource region of the control information instruction received in S401 is as illustrated in fig. 4 c, and the PUCCH resource in each PUCCH resource region is indexed as follows:

PUCCH resource region 1:

PUCCHPRB#1={1,3,5,7,9,11,13,15,17,19,21,23}

PUCCHPRB#2={2,4,6,8,10,12,14,16,18,20,22,24}

PUCCH resource region 2:

PUCCHPRB#3={1,3,5,7,9,11,13,15,17,19,21,23}

PUCCHPRB#4={2,4,6,8,10,12,14,16,18,20,22,24}

In this example it is assumed that the equipment of this Bandwidth-Constrained is the MTC device (CE-MTC) needing coverage enhancement, and its PUCCH needs to repeat transmission N=8 time. According to embodiments of the invention, it is possible to transmit the number (resource area number is 2 in this example) divided by the PUCCH resource region being instructed to by 8 times, obtain the number of times repeating transmission performed in each resource area. Thus, it is possible to obtain perform 8/2=4 time to repeat in each resource area. Assuming that the EPDCCH used impliedly indicates the PUCCH resource 9 in PUCCH resource region 1, the PUCCH resource 9 then can passed through in the PRB#1 in PUCCH resource region 1 performs the 1 to 4th repetition, and the PUCCH resource 9 in the PRB#3 in PUCCH resource region 2 performs the 5-8 time to repeat to obtain diversity gain. This repeats transmission and schematically shows in figure 4d. As can be seen here, in an embodiment of the present invention, the resource for PUCCH transmission can be the function of number of repetition.

According to embodiments of the invention, the transmission of step S403 is at more than one, such as N > 1 subframe completes, and the method 400 farther includes step S411, for sequentially in time described N sub-frame division being become at least two sub-frame set, and use the resource in the different resource region in this at least two resource area to be transmitted in step S403 step in different sub-frame set, as shown in Figure 4 b. According to one embodiment of present invention, this division can carry out according to predetermined rule, or operates according to the configuration signal from base station. Such as, N=16 subframe can be divided into 4 set in chronological order, thus the 1st set includes subframe 1-4, the 2nd, 3,4 set include subframe 5-8,9-12,13-16 respectively. Subframe in different sub-frame set does not overlap in time, thus being transmitted without the readjustment carrying out frequency in same resource area within the persistent period of a sub-frame set, this avoids frequency readjustment operation frequently and reduces and thus bring handover delay. Owing to the change in PUCCH region will need frequency to reset, and this frequency is resetted and will be interrupted the normal transmission of PUCCH, and therefore, this embodiment will minimize the requirement that frequency is resetted, and this is advantageous for for the transmission of bandwidth limited devices. According to embodiments of the invention, method 400 farther includes step S412, for determining the transmission gap performing frequency error factor between different sub-frame set; And in step S403, during determined described transmission gap, do not perform described transmission. This transmission gap is used for making equipment carry out frequency readjustment. Realizing according to current device, the time that this readjustment needs will less than 1 subframe lengths, for instance be likely to need several OFDM (OFDM) symbol time. Once define this transmission gap, the data sampling that this transmission gap is corresponding can be ignored, when receiving, in base station, and only remaining data is combined. Although according to embodiments of the invention, can not transmit when transmission gap, but this loss will be far smaller than diversity gain. According to one embodiment of present invention, transmission gap includes a symbol lengths, the subframe lengths of half or a subframe lengths. The 5th subframe in figure 4d has illustrated this transmission gap. The example of another transmission gap is shown in figure 4e. Wherein transmit in this example and complete N=2 subframe, and the length of transmission gap is half subframe (that is, being 1 time slot in LTE). And as a comparison, Fig. 4 e also show the schematic diagram of the PUCCH frequency hopping of normal UE. As seen from the figure, this embodiment can commonly use normal UE operation in half subframe, thus reducing the UE impact realized.

With reference now to Fig. 5 a-5b describe corresponding with strength method 400, that perform in base station end, for realizing the method 500 of the transmission of bandwidth limited devices. Fig. 5 a is according to an embodiment of the invention at the flow chart of the exemplary method of base station end.
