Description
Technical Field
The present invention relates to the field of wireless communications, and in particular, to a method, a system, and a device for subframe bundling transmission in a long term evolution multi-carrier system.
Background
In a Long Term Evolution (LTE) system, because of being limited to the transmit power of a User Equipment (UE), if the UE is in a severe environment, the quality of uplink transmission of the UE is difficult to guarantee. Therefore, a multi-subframe joint scheduling (TTI bundling) scheme is adopted for uplink transmission to improve uplink coverage, so that the quality of uplink transmission can be ensured.
In the TTI bundling scheme, the UE transmits different redundancy versions of the same data block using multiple consecutive subframes. The TTI bundling is specifically realized as follows:
a base station sends a scheduling signaling to UE, the UE determines N continuous uplink subframes in a member carrier according to the scheduling signaling, and sends N redundancy versions of a data block to the base station by utilizing the N uplink subframes, wherein the N continuous uplink subframes are called binding subframes; the base station combines the received N redundancy versions and then decodes the N redundancy versions, whether ACK feedback signaling or NACK feedback signaling is sent to the UE is determined according to whether the decoding is successful or not, and the time position for sending the ACK or the NACK is determined according to the time position of the last subframe in the binding subframes; and if the UE receives the NACK, retransmitting the N redundant versions of the data block, wherein the time position of retransmission is determined according to the time position of the first subframe in the binding subframes.
Taking a Frequency Division Duplex (FDD) system as an example, as shown in fig. 1, a UE transmits 3 redundancy versions of a data block in three consecutive subframes (subframe No. 0, subframe No. 1, and subframe No. 2), and receives ACK or NACK feedback signaling from a base station in subframe No. 6, which is separated from subframe No. 2 by 4 subframes. When data retransmission is carried out, continuous 3 uplink subframes are selected from all subframes of the (k + 2) × HARQ RTT, and 3 redundancy versions of a data block are retransmitted by utilizing the selected 3 uplink subframes, wherein k is the number of the first subframe in the continuous three subframes, and the HARQ RTT is the round trip time of the hybrid automatic repeat request.
It can be seen that, in the TTI bundling scheme, a bundled subframe is an independent resource, corresponds to one HARQ process, and only needs one scheduling signaling and one feedback signaling, the sending position of the feedback signaling corresponds to the last subframe in the bundled subframe, the retransmission position of a data block corresponds to the first subframe in the bundled subframe, and the time interval between the retransmission of the data block and the initial transmission is 2 times that of single subframe transmission.
In a long term evolution multi-carrier (LTE-a) system proposed at present, a carrier aggregation (carrier aggregation) technology is introduced, and by using the technology, bandwidth can be conveniently extended, and the system has a plurality of component carriers with different frequencies, as shown in fig. 2, the LTE-a system is composed of 3 component carriers.
In the process of implementing the invention, the inventor finds that the following technical problems exist in the prior art:
in an LTE-a system, a UE can support multiple component carriers, and if the TTI bundling scheme of the LTE system is still used, uplink coverage of the UE is poor.

Detailed Description
In order to improve uplink coverage, an embodiment of the present invention provides a subframe binding transmission method in an LTE-a system, where a terminal selects multiple uplink subframes from at least two component carriers supported by the terminal as binding subframes, and transmits multiple versions of the same data block using the selected multiple binding subframes.
Referring to fig. 3, the method for binding and transmitting subframes in an LTE-a system according to an embodiment of the present invention specifically includes the following steps:
step 30: the terminal selects at least two member carriers from the member carriers supported by the terminal as binding member carriers, and determines the number of subframes to be bound;
step 31: the terminal selects a plurality of uplink subframes from the selected at least two binding member carriers as binding subframes according to the determined number of the subframes to be bound;
step 32: and the terminal transmits the same data block by using the selected binding subframes.
In step 30, the specific ways of selecting the bonding member carrier by the terminal may be as follows:
first, a binding member carrier is selected according to a scheduling signaling of a base station. Specifically, the terminal acquires at least two member carrier identification information carried in a multi-subframe joint scheduling signaling sent by the base station, and selects a member carrier corresponding to the member carrier identification from member carriers supported by the terminal as a binding member carrier for each member carrier identification in the at least two member carrier identifications.
And secondly, selecting the binding member carrier according to the preconfigured information. Specifically, the terminal selects at least two member carriers from the member carriers supported by the terminal as binding member carriers according to a preset binding member carrier selection rule. For example, the binding component carrier selection rule may be to select a fixed component carrier as the binding component carrier, or select a component carrier satisfying a set frequency condition as the binding component carrier.
The specific ways for the terminal to determine the number of subframes to be bound may also be two of the following ways:
firstly, the number of subframes to be bound is determined according to the scheduling signaling of the base station. Specifically, the terminal obtains the number information of the subframes to be bound carried in the multi-subframe joint scheduling signaling sent by the base station, and determines the number of the subframes to be bound according to the information. For example, if the number information of the subframes to be bound carried in the multi-subframe joint scheduling signaling is 4, it is determined that the number of the subframes to be bound is 4.
And secondly, determining the number of the subframes to be bound according to the preconfigured information. Specifically, the terminal acquires the number information of the pre-configured subframes to be bound, and determines the number of the subframes to be bound according to the information.
In step 31, the specific implementation of the terminal selecting the binding subframe is as follows:
firstly, a terminal acquires uplink frame position information carried in a multi-subframe joint scheduling signaling sent by a base station, and determines the sequence relationship of at least two binding member carriers selected in the step 30 and the number of uplink subframes to be selected on each binding member carrier;
here, the terminal may determine the sequential relationship between the bound component carriers and the number of uplink subframes that need to be selected on each bound component carrier according to the scheduling signaling or the preconfigured information of the base station, that is, determine the sequential relationship between at least two bound component carriers and the number of uplink subframes that need to be selected on each bound component carrier according to the bound subframe selection mode information carried in the multi-subframe joint scheduling signaling or the preconfigured bound subframe selection mode information. For example, the binding subframe selection pattern information includes the sequential relationship among the binding component carrier 1, the binding component carrier 2, and the binding component carrier 3 as follows: the binding member carriers 1 are located in a first sequence, the binding member carriers 3 are located in a second sequence, the binding member carriers 2 are located in a third sequence, the binding subframe selection mode information further includes that the number of uplink subframes which need to be selected on the binding member carriers 1, the binding member carriers 2 and the binding member carriers 3 is 1, when binding subframes are selected subsequently, a binding subframe is selected on the binding member carriers 1 located in the first sequence firstly, then a binding subframe is selected on the binding member carriers 3 located in the second sequence, and finally a binding subframe is selected on the binding member carriers 2 located in the third sequence.
And then, the terminal selects the uplink subframes with the number of the uplink subframes needing to be selected corresponding to the binding member carrier from each binding member carrier according to the sequence relation by taking the uplink subframes corresponding to the uplink frame positions as initial frames, and determines the selected uplink subframes as the binding subframes. And the total number of the selected binding subframes is consistent with the number of the subframes to be bound. Of course, there may also be a certain determined relationship between the total number of the selected binding subframes and the number of the subframes to be bound, for example, the total number of the selected binding subframes is twice the number of the subframes to be bound. The specific implementation may include the following steps S01 to S03:
step S01: according to the sequence relation, for the binding member carriers positioned in the 1 st sequence in at least two binding member carriers, selecting the uplink sub-frames corresponding to the binding member carriers and needing to be selected from the initial frame on the binding member carriers as binding sub-frames; go to step S02;
step S02: for a binding member carrier positioned in the next sequence in at least two binding member carriers, selecting an uplink subframe corresponding to the binding member carrier and needing to select the number of uplink subframes on the binding member carrier as a binding subframe, wherein the time position of the selected uplink subframe is behind the time position of the uplink subframe selected last time and is continuous with the time position of the uplink subframe selected last time;
of course, the time position of the uplink subframe selected this time and the time position of the uplink subframe selected last time may be continuous or discontinuous, and the time position of the uplink subframe selected this time and the time position of the uplink subframe selected last time have a certain time interval, for example, a time length of 2 subframes apart.
Step S03: and judging whether the next sequential binding member carrier exists, namely whether the binding member carrier of the binding subframe which is not selected exists, if so, returning to the step S02, otherwise, ending the process.
In step 32, the specific implementation manner that the terminal transmits the same data block by using the binding subframe is as follows:
firstly, a terminal determines the corresponding relation between each binding member carrier and a data block version in at least two selected binding member carriers, wherein the data block version is one version in multiple versions of the same data block to be transmitted;
here, when the terminal determines the corresponding relationship between the binding component carrier and the data block version, the corresponding relationship between each binding component carrier and the data block version may be specifically obtained from the multi-subframe joint scheduling signaling sent by the base station, or the corresponding relationship between the binding component carrier and the data block version may be determined according to preconfigured information. A certain binding member carrier may correspond to one or more data chunk versions, and the number of the data chunk versions corresponding to the binding member carrier is consistent with the number of the binding subframes selected on the binding member carrier.
And then, for each binding member carrier in the selected at least two binding member carriers, transmitting the data block version corresponding to the binding member carrier by using the binding subframe selected from the binding member carrier. For example, if the binding component carrier 1 corresponds to version 0 of the data block, the binding component carrier 2 corresponds to version 1 and version 2 of the data block, and the binding component carrier 3 corresponds to version 3 of the data block, version 0 of the data block is transmitted using one binding subframe selected on the binding component carrier 1, version 1 of the data block is transmitted using one binding subframe selected on the binding component carrier 2, version 2 of the data block is transmitted using another binding subframe selected on the binding component carrier 3, and version 3 of the data block is transmitted using one binding subframe selected on the binding component carrier 3.
After step 32, the base station receives the multiple versions of the data block sent by the terminal, and sends a response message to the UE according to the decoding results of the multiple versions, where the response message is an Acknowledgement (ACK) message or a Negative Acknowledgement (NACK) message.
And the terminal determines the position of the member carrier and the subframe of the response message sent by the base station and receives the response message from the subframe on the member carrier. Here, when determining the positions of the component carriers and the subframes of the response message sent by the base station, the terminal may determine according to response sending position information carried in a multi-subframe joint scheduling signaling sent by the base station, or may determine according to pre-configured response sending position information. For example, the response sending location information carried in the multi-subframe joint scheduling signaling or configured in advance is that a response message is sent on the binding member carrier 3 and on the subframe with the interval of 4 subframe lengths with the binding subframe with the latest time in each selected binding subframe, and the terminal receives the response message to the data block sent by the base station according to the information from the binding member carrier 3 and the subframe with the interval of 4 subframe lengths with the latest time in each selected binding subframe.
If the response message received by the terminal is a NACK message, the terminal determines a retransmission mode for the data block, and then retransmits the versions of the data block transmitted in step 32 using the selected at least two bonded uplink carriers according to the retransmission mode. The retransmission method may specifically include the following three types:
first, for each version of multiple versions of a data block, determining a binding member carrier corresponding to the version according to the corresponding relationship between the binding member carrier and the version of the data block, and retransmitting the version by using the determined binding member carrier. That is, the same component carrier is utilized for retransmission of the same version as for initial transmission.
And secondly, determining the binding member carrier corresponding to each version of the multiple versions of the data block according to the corresponding relation between the binding member carrier and the version of the data block, and retransmitting the version by using other binding member carriers except the determined binding member carrier in the selected at least two binding uplink carriers. That is, the same version of retransmission utilizes a different component carrier than the component carrier utilized for the initial transmission.
Thirdly, retransmitting each version of the data block by using one binding uplink carrier in the selected at least two binding uplink carriers.
The first and second retransmission schemes have a common characteristic of retransmitting multiple versions of a data block using at least two bundled component carriers, and therefore, the first and second retransmission schemes are not limited to the first and second schemes described above as long as the retransmission scheme satisfying the characteristic is available. The retransmission of the multiple versions of the data block is performed by using at least two bound member carriers, so that the terminal can obtain a larger frequency gain, and the uplink coverage is further improved.
The specific retransmission mode can be determined according to preconfigured retransmission mode information or retransmission mode information carried in multi-subframe joint scheduling signaling sent by the base station.
After determining the binding member carrier utilized by each version of the retransmission data block, it is necessary to determine at what position of the binding member carrier the corresponding version is retransmitted, and the retransmission position information may be determined according to preconfigured retransmission position information or retransmission position information carried in a multi-subframe joint scheduling signaling sent by a base station. For example, the retransmission location information carried in the pre-configured or multi-subframe joint scheduling signaling may be: the same version is retransmitted on subframes separated by twice the HARQ RTT from the initial transmission of the version.
It should be noted that the present invention is applicable to a long term evolution time division duplex (LTE TDD) multi-carrier system and a long term evolution frequency division duplex (LTE FDD) multi-carrier system.
The method provided by the embodiment of the invention is explained by the following specific embodiment:
the first embodiment is as follows:
in this embodiment, the initial transmission and retransmission of each version of the data block are on the same component carrier, as shown in fig. 4A:
the number of the subframes to be bound is 3 subframes, and the member carriers to be bound are a member carrier 1, a member carrier 2 and a member carrier 3.
The UE selects a sub-frame No. 0 on the member carrier 1, selects a sub-frame No. 1 on the member carrier 2 and selects a sub-frame No. 2 on the member carrier 3 as a binding sub-frame; transmitting version 0 of the data block on the component carrier 1(RV 0), transmitting version 1 of the data block on the component carrier 2(RV 1) and transmitting version 2 of the data block on the component carrier 3 (RV 2); feeding back the ACK/NACK on the sub-frame No. 6 on the member carrier 3, namely, feeding back the ACK/NACK at the time of 4 sub-frames separated from the third binding sub-frame, namely, the binding sub-frame with the latest time position; when the data block is retransmitted, the retransmission of each version and the initial transmission of the version are on the same component carrier, and the time of the retransmission of each version and the time interval of the initial transmission of the version are twice of the HARQ RTT.
Example two:
in this embodiment, the initial transmission and the retransmission of the same version of the data block are not completely on the same component carrier, as shown in fig. 4B:
the number of the subframes to be bound is still 3 subframes, and the member carriers to be bound are a member carrier 1, a member carrier 2 and a member carrier 3.
The UE selects a sub-frame No. 0 on the member carrier 1, selects a sub-frame No. 1 on the member carrier 2 and selects a sub-frame No. 2 on the member carrier 3 as a binding sub-frame; transmitting version 0 of the data block on the component carrier 1(RV 0), transmitting version 1 of the data block on the component carrier 2(RV 1) and transmitting version 2 of the data block on the component carrier 3 (RV 2); feeding back a No. 5 subframe of ACK/NACK on the member carrier 2, namely feeding back time which is 4 subframes separated from a second binding subframe, namely the binding subframe selected on the member carrier 2; when retransmitting the data block, the retransmission mode is that the retransmission of version 0 of the data block is on the component carrier 3, the retransmission of version 1 is on the component carrier 2, the retransmission of version 2 is on the component carrier 1, and the retransmission time of each version is twice the HARQ RTT of the initial transmission time interval of the version.
Example three:
in this embodiment, a plurality of UEs time division and frequency division multiplex a group of bound resources, as shown in fig. 4C:
for UE1, UE2, and UE3, the number of subframes to be bonded is 3 subframes, and the component carriers to be bonded are all component carrier 1, component carrier 2, and component carrier 3.
For the UE1, selecting the subframe 0 on the component carrier 1, the subframe 1 on the component carrier 2, and the subframe 2 on the component carrier 3 as binding subframes; transmitting version 0 of the data block on the component carrier 1(RV 0), transmitting version 1 of the data block on the component carrier 2(RV 1) and transmitting version 2 of the data block on the component carrier 3 (RV 2); feeding back ACK/NACK on the sub-frame 6 on the member carrier 3; when retransmitting the data block, the retransmission mode is that the retransmission of version 0 of the data block is on the component carrier 3, the retransmission of version 1 is on the component carrier 2, the retransmission of version 2 is on the component carrier 1, and the retransmission time of each version is twice the HARQ RTT of the initial transmission time interval of the version.
For the UE2, selecting the subframe number 1 on the component carrier 1, the subframe number 2 on the component carrier 2, and the subframe number 0 on the component carrier 3 as binding subframes; transmitting version 0 of the data block on the component carrier 1(RV 0), transmitting version 1 of the data block on the component carrier 2(RV 1) and transmitting version 2 of the data block on the component carrier 3 (RV 2); feeding back the ACK/NACK on the sub-frame 6 on the component carrier 2; when retransmitting the data block, the retransmission mode is that the retransmission of version 0 of the data block is on the component carrier 1, the retransmission of version 1 is on the component carrier 3, the retransmission of version 2 is on the component carrier 2, and the retransmission time of each version is twice the HARQ RTT of the time interval of the initial transmission of the version.
For the UE3, selecting the subframe No. 2 on the member carrier 1, the subframe No. 0 on the member carrier 2, and the subframe No. 1 on the member carrier 3 as binding subframes; transmitting version 0 of the data block on the component carrier 1(RV 0), transmitting version 1 of the data block on the component carrier 2(RV 1) and transmitting version 2 of the data block on the component carrier 3 (RV 2); feeding back ACK/NACK on the No. 6 subframe on the component carrier 1; when retransmitting the data block, the retransmission mode is that the retransmission of version 0 of the data block is on the component carrier 2, the retransmission of version 1 is on the component carrier 1, the retransmission of version 2 is on the component carrier 3, and the retransmission time of each version is twice the HARQ RTT of the initial transmission time interval of the version.
It can be seen that, in this embodiment, if the subframes 0 to 2 on the component carrier 1, the component carrier 2, and the component carrier 3 are used as a group of bonding resources, the UE1, the UE2, and the UE3 multiplex the bonding resources through reasonable selection of the bonding subframes.
When the number of the bound member carriers is not consistent with the number of the subframes to be bound, for example, only 3 member carriers are provided, but the number of the subframes to be bound is 4, only two member carriers can be selected as the bound member carriers, that is, each bound member carrier sends 2 versions of the data block. Or 3 member carriers can be selected as the binding member carriers, but one binding member carrier sends 2 versions of the data block, and the other two binding member carriers send 1 version of the data block.
