The present disclosure relates to the field of mobile communication technology, in particular to a transmission method, a transmission device, a mobile communication terminal and a network side device, so as to achieve bundling transmission of an uplink shared channel.
Subframe structures having an equal length are adopted by a Time Division Long Term Evolution (TD-LTE) system. Each subframe has a length of 1 ms and includes two time slots each having a length of 0.5 ms. A radio frame includes 10 subframes, i.e., the radio frame has a length of 10 ms. A basic transmission Time Interval (TTI) for the TD-LTE system has a length equal to one subframe, i.e., 1 ms. Correspondingly, an interval between a TTI for feedback and a TTI for data transmission needs to be set in accordance with such factors as a data transmission time delay and a data processing time period of a device, and usually, this interval has a length of 4 TTIs. In addition, a special subframe has been introduced into the TD-LTE system. The special subframe consists of a Downlink Pilot Time Slot (DwPTS), a Guard Period (GP), and an Uplink Pilot Time Slot (UpPTS).
For the LTE system, a basic unit scheduled at a physical layer is 1 ms, and due to such a small time interval, it is able to provide a relatively small time delay in the LTE system. However, the coverage is limited at edges of some cells. Due to limited transmission power of a User Equipment (UE), it is probably impossible for the UE to meet a requirement on Block Error Rate (BLER) for the data transmission within the time interval of 1 ms. Hence, such a concept as TTI bundling has been proposed for the LTE system. To be specific, consecutive TTIs for uplink transmission are bundled together and allocated for a same UE. In this way, it is able to increase a probability of successful data decoding, thereby to increase uplink coverage. Upon the receipt of all the bundled uplink subframes, a network side device may return Acknowledgement (ACK)/Non-Acknowledgement (NACK).
However, the transmission of a Physical Uplink Shared Channel (PUSCH) within the special subframe is not supported by a conventional protocol, and during the transmission of the PUSCH, the TTI bundling transmission is not supported in some Time Division Duplexing (TDD) subframe configurations (e.g., configurations #2 and #3). Hence, the uplink coverage for some subframe configurations is relatively insufficient.
An object of the present disclosure is to provide a transmission method, a transmission device, a mobile communication terminal, and a network side device, so as to achieve the bundling transmission of an uplink shared channel.

According to the embodiments of the present disclosure, the PUSCH is transmitted within the UpPTS, and when the TTI bundling transmission condition has been met, the transmission of the PUSCH is achieved through a TTI bundling technology. As a result, it is able to improve the uplink coverage.
In order to illustrate the technical solutions of the present disclosure or the related art in a clearer manner, the drawings desired for the present disclosure or the related art will be described hereinafter briefly. Obviously, the following drawings merely relate to some embodiments of the present disclosure, and based on these drawings, a person skilled in the art may obtain the other drawings without any creative effort.
In order to make the objects, the technical solutions and the advantages of the present disclosure more apparent, the present disclosure will be described hereinafter in a clear and complete manner in conjunction with the drawings and embodiments. Obviously, the following embodiments merely relate to a part of, rather than all of, the embodiments of the present disclosure, and based on these embodiments, a person skilled in the art may, without any creative effort, obtain the other embodiments, which also fall within the scope of the present disclosure.
In the embodiments of the present disclosure, an UpPTS is scheduled so as to transmit a PUSCH, and the transmission of the PUSCH is achieved through a TTI bundling technology. As a result, it is able to improve the uplink coverage.
The present disclosure provides in some embodiments a transmission method which, as shown in
According to the embodiments of the present disclosure, the PUSCH is transmitted within the UpPTS, and when the TTI bundling transmission condition has been met, the transmission of the PUSCH is achieved through a TTI bundling technology. As a result, it is able to improve the uplink coverage.
In the embodiments of the present disclosure, the uplink resources within the UpPTS and an uplink subframe may be bundled together for the transmission of the PUSCH. The quantity of the uplink resources within the UpPTS may be different from the quantity of the uplink resources within the uplink subframe. For example, for a special subframe within which DwPTS:GP:UpPTS is 6:2:6, usually the quantity of the resources within the UpPTS is 43% ( 6/14) of the quantity of the uplink resources within the uplink subframe. At this time, when a size of a transmission block is determined on the basis of the resources within the UpPTS, the transmission efficiency of the normal uplink subframe may be reduced due to the relatively large quantity of available resources within the uplink subframe. When the size of the transmission block is determined on the basis of the uplink resources within the uplink subframe, an encoding rate of the PUSCH transmitted within the UpPTS may be greater than 1 and the transmission performance may be adversely affected due to the relatively small quantity of available resources within the UpPTS.
Considering the above factors, in a possible embodiment of the present disclosure, an appropriate transmission block may be determined for each of the uplink subframe and the UpPTS, so as to improve the transmission performance and the transmission efficiency.
In the first transmission step, the quantity N′ of physical blocks to be allocated for the UpPTS may be determined in accordance with the quantity N of physical blocks allocated by a network side device for the uplink subframe through the formula N′=[α*N], where [ ] represents a rounding operation, and a represents a scaling coefficient.
In a possible embodiment of the present disclosure, N′ may be determined in accordance with the quantity KNormal of symbols available for the transmission of the PUSCH within the uplink subframe and the quantity KUpPTS of symbols available for the transmission of the PUSCH within the UpPTS, and α=KNormal/KUpPTS.
When the quantity KNormal of the symbols available for the transmission of the PUSCH within the uplink subframe is 1, α=12; when KNormal is 2, α=6; when KNormal is 3, α=4; when KNormal is 5, α=2.4; and when KNormal is 6, α=2, and so on.
As mentioned above, the quantity of the physical blocks within the UpPTS may be scaled up in accordance with the ratio of KNormal to KUpPTS.
When the quantity of the physical blocks within the uplink subframe is different from the quantity of the physical blocks within the UpPTS, transmission power may be configured for each of the uplink subframe and the UpPTS. The transmission power for the transmission of the PUSCH within the UpPTS of the first start subframe may be determined in accordance with N′. As specified in the 3rd-Generation Partnership Projection (3GPP) Technical Specification (TS) 36.213, PPUSCH(i)=min {PCMAX,10 log10(MPUSCH(i))+PO_PUSCH(j)+α(j)·PL+ΔTF(i)+f(i)}, where MPUSCH(i) represents the quantity N′ of the physical blocks allocated for the UpPTS.
During the allocation of the resources, it is necessary to determine the quantity of the physical blocks as well as a start position of each of the UpPTS and the uplink subframe at a frequency domain. In a possible embodiment of the present disclosure, at the frequency domain, a start position of the UpPTS of the special subframe for the transmission of the PUSCH may be the same as a start position of the uplink subframe for the transmission of the PUSCH.
In a possible embodiment of the present disclosure, in the subframe determination step, a position of the first start subframe may be determined in accordance with a position of a reference subframe in a current frame structure and an uplink-downlink configuration of the current frame structure.
The reference subframe may be a subframe where an uplink grant is located or a subframe within which a PHICH has been received.
Table 1 shows conventional TDD subframe configurations.
As shown in Table 1, for TDD subframe configurations #0, #1 and #6, the quantities of the uplink subframes are 6, 4 and 5 respectively, so it is able to achieve the TTI bundling. For TDD subframe configurations #4 and #5, sums of the uplink subframes and the special subframes are 2 and 3 respectively, and at this time, even when the PUSCH is capable of being transmitted within the UpPTS of each special subframe, it is still impossible to achieve the TTI bundling due to the quantities thereof.
Hence, the scheme in the embodiments of the present disclosure may be at first designed for the uplink-downlink configurations #2 and #3 so as to achieve the TTI bundling transmission of the PUSCH. Corresponding criterions will be described as follows.
At first, a time interval between the uplink grant and a first one of the scheduled, bundled TTIs shall be as short as possible. Taking the uplink-downlink configuration #3 as an example, when the uplink grant is located at a subframe 6, the first one of the scheduled, bundled TTIs shall be a first special subframe, rather than a subsequent TTI.
Next, considering the compatibility with a conventional UE, when a last TTI of the bundled TTIs is the UpPTS, the PHICH corresponding to the PUSCH shall merely be transmitted on an original PHICH resource.
Next, a sequence of the normal subframes shall be affected by a newly-designed sequence as small as possible.
Finally, an interval between the uplink grant transmission and the data transmission shall be not smaller than 4 ms, and an interval between the data transmission and ACK/NACK feedback shall be not smaller than 4 ms either.
It should be appreciated that, it is not required to follow the above criterions, and instead, these criterions are merely adopted so as to reduce the design difficulty and the system complexity.
<Uplink-Downlink Configuration #2>
For the uplink-downlink configuration #2, two special time slots are included and located in a subframe 2 and a subframe 6 respectively. In order to transmit the PUSCH within the subframe 2 and the subframe 6, the following schemes will be provided.
Scheme 1
When the reference subframe is a subframe where the uplink grant is located and the uplink grant is to be transmitted within a subframe N1 for the uplink-downlink configuration #2, the PUSCH may be transmitted from a subframe N1+K1, and there are the following two schemes.
When N1 is 0 or 5, K1 is 6, and when N1 is 3 or 8, K1 is 4, and when N1 is 0, K1 is 6, as shown in Table 2.
Considering the above four criterions, when a subframe design scheme for the transmission of the PUSCH in Table 2 (i.e., the subframe N1+K1 within which the PUSCH is transmitted) corresponds to the subframe within which the PHICH has been received and the reference subframe is the subframe within which the PHICH has been received, a subframe within which the PHICH was received previously is N3−L1 (N3 is equal to N1), and the position of the first start subframe is N3+K3 (K3 is equal to K1). When N3 is 0 or 5, L1 is 2 and K3 is 6, and when N3 is 3 or 8, L1 is 0 and K3 is 4. Table 3 shows the design of L1.
Alternatively, L1 may also be designed in any other way. For example, a time interval between the PHICH and a last TTI of the bundled TTIs corresponding to ACK may be provided as short as possible.
In the case that a design criterion is changed, a corresponding design scheme of L1 may be described as follows. When the subframe design scheme for the transmission of the PUSCH in Table 2 (i.e., the subframe N1+K1 within which the PUSCH is transmitted) corresponds to the subframe within which the PHICH has been received and the reference subframe is the subframe within which the PHICH has been received, a subframe within which the PHICH was received previously is N3−L1 (N3 is equal to N1), and the position of the first start subframe is N3+K3 (K3 is equal to K1). When N3 is 0 or 5, L1 is 2 and K3 is 6, and when N3 is 3 or 8, L1 is 3 and K3 is 4. Table 4 shows the design of L1.
Scheme 2
When the reference subframe is the subframe where the uplink grant is located, for the uplink-downlink configuration #2, the position of the reference subframe in the current frame structure is N2, and the position of the first start subframe is N2+K2. When N2 is 1 or 6, K2 is 5, and when N2 is 3 or 8, K2 is 4, as shown in Table 5.
Considering the above four criterions, when a subframe design scheme for the transmission of the PUSCH in Table 5 (i.e., the subframe N1+K1 within which the PUSCH is transmitted) corresponds to the subframe within which the PHICH has been received and the reference subframe is the subframe within which the PHICH has been received, the position of the reference subframe in the current frame structure is N4−L2 (N4 is equal to N2), and the position of the first start subframe is N4+K4 (K4 is equal to K2). Table 6 shows the design of L2.
Alternatively, L2 may also be designed in any other way. For example, the time interval between the PHICH and the last TTI of the bundled TTIs corresponding to the ACK may be provided as short as possible.
In the case that a design criterion is changed, a corresponding design scheme of L2 may be described as follows. When the subframe design scheme for the transmission of the PUSCH in Table 5 (i.e., the subframe N1+K1 within which the PUSCH is transmitted) corresponds to the subframe within which the PHICH has been received and the reference subframe is the subframe within which the PHICH has been received, the position of the reference subframe in the current frame structure is N4−L2 (N4 is equal to N2), and the position of the first start subframe is N4+K4 (K4 is equal to K2). Table 7 shows the design of L2.
In Tables 2-7, for an end subframe for the transmission of the PUSCH, there are the following four circumstances. When the uplink grant is transmitted within a subframe 0 or 1, a start subframe for the transmission of the PUSCH is the subframe 6, and four subframes each having the uplink resources are adopted, so the transmission of the PUSCH may be ended within a subframe 2. When the uplink grant is transmitted within a subframe 3, a start subframe for the transmission of the PUSCH is a subframe 7, and four subframes each having the uplink resources are adopted, so the transmission of the PUSCH may be ended within the subframe 6. When the uplink grant is transmitted within a subframe 5 or 6, a start subframe for the transmission of the PUSCH is the subframe 1, and four subframes each having the uplink resources are adopted, so the transmission of the PUSCH may be ended within the subframe 7. When the uplink grant is transmitted within a subframe 8, a start subframe for the transmission of the PUSCH is the subframe 2, and four subframes each having the uplink resources are adopted, so the transmission of the PUSCH may be ended within the subframe 1.
In a possible embodiment of the present disclosure, as shown in
A position of the second start subframe is determined in accordance with a position of a last subframe for the transmission of the PUSCH in the current frame structure and the uplink-downlink configuration of the current frame structure.
For the uplink-downlink configuration #2, in the above design scheme, there are the above four circumstances for the last subframe for the transmission of the PUSCH, i.e., the last subframe is the subframe 1, the subframe 2, the subframe 6 or the subframe 7. When the position of the last subframe in the current frame structure is N8 (N8 is equal to N1+K1 or N2+K2), the position of the second start subframe is N8+K8. When N8 is 1 or 6, K8 is 7, and when N8 is 2 or 7, K8 is 6, as shown in Table 8.
Alternatively, K8 may be designed in any other way. For example, the time interval between the PHICH and the last TTI of the bundled TTIs corresponding to the ACK may be provided as short as possible.
In the case that a design criterion is changed, a corresponding design scheme of K8 may be described as follows. When the position of the last subframe in the current frame structure is N8 (N8 is equal to N1+K1 or N2+K2), the position of the second start subframe is N8+K8. When N8 is 1 or 6, K8 is 4, and when N8 is 2 or 7, K8 is 6, as shown in Table 9.
<Uplink-Downlink Configuration #3>
For the uplink-downlink configuration #3, one special time slot is included and located in the subframe 2. In order to transmit the PUSCH within the subframe 2, the following schemes will be provided.
Scheme 1
When the reference subframe is the subframe where the uplink grant is located and the uplink grant is to be transmitted within a subframe N5 for the uplink-downlink configuration #3, the PUSCH may be transmitted from a subframe N5+K5. When N5 is 0, 7, 8 or 9, K5 is 4, as shown in Table 10.
When a subframe design scheme for the transmission of the PUSCH in Table 10 (i.e., the subframe N5+K6 within which the PUSCH is transmitted) corresponds to the subframe within which the PHICH has been received and the reference subframe is the subframe within which the PHICH has been received, a subframe within which the PHICH was received previously is N6−L3 (N6 is equal to N5). Table 11 shows the design of L3.
Alternatively, L3 may also be designed in any other way. For example, the time interval between the PHICH and the last TTI of the bundled TTIs corresponding to the ACK may be provided as short as possible.
In the case that a design criterion is changed, a corresponding design scheme of L4 may be described as follows. When the subframe design scheme for the transmission of the PUSCH in Table 10 (i.e., the subframe N5+K6 within which the PUSCH is transmitted) corresponds to the subframe within which the PHICH has been received and the reference subframe is the subframe within which the PHICH has been received, a subframe within which the PHICH was received previously is N7−L4 (N7 is equal to N5). Table 12 shows the design of L4.
In Tables 10-12, for the end subframe for the transmission of the PUSCH, there are the following four circumstances. When the uplink grant is transmitted within the subframe 0, a start subframe for the transmission of the PUSCH is the subframe 4, and four subframes each having the uplink resources are adopted, so the transmission of the PUSCH may be ended within the subframe 3. When the uplink grant is transmitted within the subframe 7, a start subframe for the transmission of the PUSCH is the subframe 1, and four subframes each having the uplink resources are adopted, so the transmission of the PUSCH may be ended within the subframe 4. When the uplink grant is transmitted within the subframe 8, a start subframe for the transmission of the PUSCH is the subframe 2, and four subframes each having the uplink resources are adopted, so the transmission of the PUSCH may be ended within the subframe 1. When the uplink grant is transmitted within the subframe 9, a start subframe for the transmission of the PUSCH is the start subframe 3, and four subframes each having the uplink resources are adopted, so the transmission of the PUSCH may be ended within the subframe 2.
For the uplink-downlink configuration #3, the transmission method further includes a first reception step of receiving, within a second start subframe, the PHICH corresponding to the PUSCH transmitted in the first transmission step.
A position of the second start subframe is determined in accordance with a position of a last subframe for the transmission of the PUSCH in the current frame structure and the uplink-downlink configuration of the current frame structure.
For the uplink-downlink configuration #3, in the above design scheme, there are the above four circumstances for the last subframe for the transmission of the PUSCH, i.e., the last subframe is the subframe 1, the subframe 2, the subframe 3 or the subframe 4. When the position of the last subframe in the current frame structure is N9 (N9 is equal to N5+K5), the position of the second start subframe is N9+K9. When N9 is 1, K9 is 7, and when N9 is 2, 3 or 4, K9 is 6, as shown in Table 13.
Alternatively, K9 may be designed in any other way. For example, the time interval between the PHICH and the last TTI of the bundled TTIs corresponding to the ACK may be provided as short as possible.
In the case that a design criterion is changed, a corresponding design scheme of K10 may be described as follows. For the uplink-downlink configuration #3, there are the above four circumstances for the last subframe for the transmission of the PUSCH, i.e., the last subframe is the subframe 1, the subframe 2, the subframe 3 or the subframe 4. When the position of the last subframe in the current frame structure is N10 (N10 is equal to N5+K5), the position of the second start subframe is N10+K10. When N10 is 1, K10 is 6 or 4, and when N10 is 2, 3 or 4, K10 is 6, as shown in Table 14.
In a possible embodiment of the present disclosure, when the PUSCH is transmitted in accordance with the above-mentioned sequence through the TTI bundling, the quantity of Hybrid Automatic Repeat reQuest (HARQ) processes may be 2.
The actual transmission corresponding to parts of the sequence diagrams will be described hereinafter.
