Description
Technical field
The present invention relates to mobile communication, particularly, relate to the method for sending/receiving HARQ message, base station and subscriber equipment.
Background technology
In third generation partner plan (3GPP) Long Term Evolution (LTE) system, base station (also referred to as NodeB or evolution NodeB (eNB)) is for example upper to subscriber equipment (UE) transmission data at Physical Downlink Shared Channel (PDSCH).As response, UE is in for example Physical Uplink Shared Channel (PUSCH) or upper mixed automatic retransfer request (HARQ) message (affirmative acknowledgement ACK or negative response NACK) that sends to base station of Physical Uplink Control Channel (PUCCH).Here, UE can be user terminal, user node, mobile terminal or panel computer.
3GPP LTE version 10 stipulated HARQ sequential (timing, or be called link link or contact association).Here, HARQ sequential has been specified for the subframe of transmitting downlink data and for transmitting as the relation between the subframe of corresponding HARQ message.
3GPP LTE version 10 has also been stipulated time division duplex (TDD) uplink-downlink configuration scheme (TDD uplink-downlink configuration scheme (TDD Uplink-Downlink Configuration) 0-6) and conversion thereof.When the TDD uplink-downlink configuration scheme in single carrier dynamically changes, need to carry out corresponding change to HARQ sequential.
Prior art document R1-120513,3GPP TSG RAN WG1 Meeting #68, Alcatel-Lucent Shanghai Bell, Alcatel-Lucent has proposed a kind of HARQ sequential when TDD uplink-downlink configuration scheme dynamically changes.R1-120513 has proposed the problem of the potential HARQ timing conflict that the change due to TDD uplink-downlink configuration scheme causes, and adopts following two kinds of solutions.The first solution is to ignore HARQ timing conflict not carry out any processing.The second solution comprises: the nearest uplink/downlink subframe that the HARQ message (ACK/NACK) of binding is delayed to Physical Uplink Shared Channel (PUSCH)/PDSCH; By remap the respectively nearest uplink/downlink subframe of to PUSCH/PDSCH at least 4 Transmission Time Intervals of ACK/NACK; And the ACK/NACK subframe that the ACK/NACK subframe link of previous subframe is changed in the descending sub frame that HARQ conflict has occurred links.
Yet, according to the first solution in R1-120513, if there is HARQ timing conflict, will cause HARQ retransmitting message.Unnecessary re-transmission causes performance loss.Although in the situation that the change of TDD uplink-downlink configuration scheme occurs the hundreds of milliseconds of orders of magnitude, this performance loss is acceptable.But for the TDD uplink-downlink configuration scheme changing frame by frame, this performance loss is unacceptable.On the other hand, according to the second solution in R1-120513, because it has defined the new HARQ sequential that does not meet LTE version 10, therefore need to carry out larger modification to standard.
Therefore, need a kind of HARQ sequential configuration, the in the situation that of can TDD uplink-downlink configuration scheme dynamically changes frame by frame in single carrier, correctly send HARQ message, and minimize the impact on current standard.

According to embodiments of the invention, HARQ message is affirmative acknowledgement ACK or negative response NACK message.
Determining unit 120 is determined will send the HARQ message corresponding with Physical Downlink Shared Channel downlink data in descending sub frame based on the first scheme in the subframe based on alternative plan.
Particularly, selected cell 130 is configured to: if the position of the specified sub-frame of uplink corresponding with described descending sub frame of the 2nd HARQ sequential can be used for sending HARQ message in alternative plan, based on the 2nd HARQ sequential, select for sending the subframe of described HARQ message.

Further, selected cell 130 is configured to, determining whether any one in meeting the following conditions: i) position of the specified sub-frame of uplink corresponding with described descending sub frame of the 2nd HARQ sequential is not useable for sending HARQ message (HARQ conflict) in alternative plan, and ii) the 2nd HARQ sequential do not specify the position (HARQ loss) of the sub-frame of uplink corresponding with described descending sub frame.If satisfy condition i) and condition ii) in any one, the position of the specified sub-frame of uplink corresponding with described descending sub frame of the 2nd HARQ sequential is not useable for sending the position that HARQ message or the 2nd HARQ sequential are not specified the sub-frame of uplink corresponding with described descending sub frame in alternative plan, and selected cell 130 determines whether the position of the sub-frame of uplink corresponding with described descending sub frame that a HARQ sequential is specified can be used for sending HARQ message in alternative plan.If the position of the sub-frame of uplink corresponding with described descending sub frame that a HARQ sequential is specified can be used for sending HARQ message in alternative plan, selected cell 130 is selected for sending the subframe of described HARQ message based on a HARQ sequential.
In addition, selected cell 130 is also configured to: if satisfy condition i) and condition ii) in any one, and the position of the sub-frame of uplink corresponding with described descending sub frame that a HARQ sequential is specified is not useable for sending HARQ message in alternative plan, and the scheduled timing based on being different from the first and second HARQ sequential is selected for sending the subframe of described HARQ message.

The operation of the unit of UE 100 is below described by concrete example.One skilled in the art will recognize that and the invention is not restricted to concrete example described below.As long as the corresponding units above-mentioned principle according to the present invention of UE 100 operates, just can realize object of the present invention.
First, according to 3GPP TS 36.211 V10.3.0 (2011-09) " the table 4.2-2 in Physical Channels and Modulation (Release 10), following table 1 shows the ascending-descending subframes ratio of TDD uplink-downlink configuration scheme:
| TDD uplink-downlink configuration scheme | ?0 | ?1 | ?2 | ?3 | ?4 | ?5 | ?6 |
| Ascending-descending subframes ratio | ?6∶4 | ?4∶6 | ?2∶8 | ?3∶7 | ?2∶8 | ?1∶9 | ?5∶5 |
The ascending-descending subframes ratio of table 1-TDD uplink-downlink configuration scheme
According to the descending of ascending-descending subframes ratio, by TDD uplink-downlink configuration scheme 0-6 sequence, be 0,6,1,3,4,2,5.According to the descending of ascending-descending subframes ratio, table 2 shows TDD uplink-downlink configuration scheme from the TDD uplink-downlink configuration scheme C of n frame
nbe converted to the TDD uplink-downlink configuration scheme C of n+1 frame
n+1translation type.
The translation type of table 2-TDD uplink-downlink configuration scheme
In table 2, by the TDD uplink-downlink configuration scheme C from n frame
ntDD uplink-downlink configuration scheme C to n+1 frame
n+1conversion be divided into 3 kinds of translation types.Suppose C
nthere is ascending-descending subframes and compare r
n, C
n+1there is ascending-descending subframes and compare r
n+1.In general, if r
nbe more than or equal to r
n+1, from C
nto C
n+1conversion there is type A; If r
nbe less than or equal to r
n+1, from C
nto C
n+1conversion there is type B; But there is exception types E, as shown in table 2.It will be appreciated by those skilled in the art that the conversion classification is here only exemplary, so that explain principle of the present invention.As long as meet principle of the present invention, can use any conversion classification.
Here, suppose C
ncorresponding to HARQ sequential R
n, as mentioned above, R
nappointment is according to C
nfor the descending sub frame of transmitting downlink data (as at PDSCH) and for transmitting the corresponding relation as the sub-frame of uplink of the HARQ message responding.Similarly, C
n+1corresponding to HARQ sequential R
n+1, R
n+1appointment is according to C
n+1the descending sub frame for transmitting downlink data with for transmitting the corresponding relation of sub-frame of uplink as the HARQ message of response.Here, R
nand R
n+1for example in 3GPP TS 36.213 V10.4.0 (2011-12) " the HARQ sequential defining in the table 10.1.3.1-1 in Physical layer procedures (Release10).
In this example, converting unit 110 is according to the signaling from base station, the C by TDD uplink-downlink configuration scheme from n frame (and frame) before n frame
nbe converted to the C of n+1 frame
n+1.
Determining unit 120 can be identified for the subframe of transmitting downlink data and affiliated radio frames thereof and for transmitting as the subframe of the HARQ message of response and affiliated radio frames thereof.If downlink data in n frame (according to C
n) transmission, corresponding HARQ message also in n frame (according to C
n) send, selected cell 130 can be according to R
nselect for sending the subframe of described HARQ message, irrelevant with above-mentioned translation type.If downlink data in n+1 frame (according to C
n+1) transmission, corresponding HARQ message also in n+1 frame (according to C
n+1) send, selected cell 130 can be according to R
n+1select for sending the subframe of described HARQ message.In both cases, downlink data and HARQ message in same number of frames (according to identical C) are transmitted, so the selection of selected cell 130 and above-mentioned translation type A, B, E are irrelevant.
According to embodiments of the invention, determining unit 120 determines, with in n frame (or n-1 frame) (according to C
n) subframe i in the corresponding HARQ message of downlink data transmitted will be (according to C in n+1 frame
n+1) send, the selected cell 130 application rule corresponding with above-mentioned translation type selected for sending the subframe of described HARQ message.
Rule a corresponding with translation type A, according to regular a, in the subframe i for downlink data in n frame (according to C
n) transmission, and corresponding HARQ message in n+1 frame (according to C
n+1) situation about sending, selected cell 130 is according to R
n+1select for sending the subframe of described HARQ message.
In other words, for translation type A, R
n+1the position of the specified sub-frame of uplink corresponding with subframe i is at C
n+1in can be used for sending HARQ message.Therefore, selected cell 130 is according to R
n+1select for sending the subframe of described HARQ message.
Rule b corresponding with translation type B, according to regular b, in the subframe i for downlink data in n frame (according to C
n) transmission, and corresponding HARQ message in n+1 frame (according to C
n+1) situation about sending, selected cell 130 is according to R
nand R
n+1select for sending the subframe of described HARQ message.
For example,, for translation type B, if R
n+1the position of the specified sub-frame of uplink corresponding with subframe i is at C
n+1in can be used for sending HARQ message, selected cell 130 is according to R
n+1select for sending the subframe of described HARQ message.
Alternatively, for translation type B, if R
nand R
n+1the position of the specified sub-frame of uplink corresponding with subframe i is at C
n+1in all can be used for sending HARQ message, selected cell 130 is according to R
nselect for sending the subframe of described HARQ message.
Further, if R
n+1the position of the specified sub-frame of uplink corresponding with subframe i is at C
n+1in be not useable for sending HARQ message, if or R
n+1do not specify the position of the sub-frame of uplink corresponding with subframe i, but R
nthe position of the specified sub-frame of uplink corresponding with subframe i is at C
n+1in can be used for sending HARQ message, selected cell 130 is according to R
nselect for sending the subframe of described HARQ message.
For example,, for translation type B, if according to R
nto in the subframe 2-4 of n+1 frame, send HARQ message, R
nand R
n+1the position of the specified sub-frame of uplink corresponding with subframe i is at C
n+1in all can be used for sending HARQ message.In this case, selected cell 130 can be according to R
n+1select for sending the subframe of described HARQ message.Alternatively, selected cell 130 can be according to R
nselect for sending the subframe of described HARQ message.For according to R
nwill in the subframe 2-4 of n+1 frame, send the situation of HARQ message, selected cell 130 can be preferably according to R
nselect for sending the subframe of described HARQ message.
As another example, for translation type B, if according to R
nto in the subframe 7-9 of n+1 frame, send HARQ message, R
nand R
n+1the position of the specified sub-frame of uplink corresponding with subframe i is at C
n+1in all can be used for sending HARQ message.In this case, selected cell 130 can be according to R
n+1select for sending the subframe of described HARQ message.Alternatively, selected cell 130 can be according to R
