A terminal determines the size M of a feedback window corresponding to an uplink sub-frame, determines a response message of each downlink sub-frame in the feedback window when the M is an integer more than 1, and transmits the feedback information corresponding to the obtained M response messages in the multiplexing feedback mode on a physical unlink control channel, thereby solving the feedback problem of the downlink sub-frame response message when the M is more than 1 and the physical unlink control channel (PUCCH) employs the acknowledged/non-acknowledged (ACK/NACK) multiplexing feedback mode. The feedback method further comprises the feedback method of downlink sub-frame response message when the size of feedback window of an uplink sub-frame is equal to 1, and the method solves the feedback problem of the downlink sub-frame response message when the M is equal to 1 and the PUCCH employs the multiplexing feedback mode. The feedback method can accurately feedback the data reception result of the downlink sub-frame while reducing the false probability of the base station.
Description
Technical Field
The present invention relates to the field of communications, and in particular, to a method for feeding back response information of a downlink subframe on an uplink channel.
Background
In the HARQ (Hybrid Automatic Repeat Request) mode, a code sent by a sending end not only can detect an error, but also has a certain error correction capability. After receiving the code word, the decoder at the receiving end firstly checks the error condition, if the error condition is within the error correction capability of the code, the error correction is automatically carried out, if the error condition is too many, the error condition exceeds the error correction capability of the code, but the error condition can be detected, the receiving end sends a judgment signal to the sending end through a feedback channel, and the sending end is required to resend information. In an OFDM (Orthogonal Frequency Division multiplexing) system, whether retransmission is required or not is determined by indicating transmission correctness/inaccuracy through acknowledgement/Non-acknowledgement (ACK/NACK) control signaling.
A Long Term Evolution (Long Term Evolution, LTE for short) system is an important project of the third generation partnership organization, and fig. 1 shows a structural diagram of a basic frame structure in the LTE system, wherein the frame structure is divided into four levels of a radio frame, a field, a subframe, a slot and a symbol, wherein the length of one radio frame is 10ms, one radio frame is composed of two fields, the length of each field is 5ms, one field is composed of 5 subframes, the length of each subframe is 1ms, one subframe is composed of two slots, and the length of each slot is 0.5 ms.
When the LTE system employs a conventional cyclic prefix, one slot includes 7 uplink/downlink symbols with a length of 66.7us, where the cyclic prefix length of the first symbol is 5.21us, and the cyclic prefix length of the other 6 symbols is 4.69 us. When the LTE system employs an extended cyclic prefix, one slot contains 6 uplink/downlink symbols with a length of 66.7us, where the cyclic prefix length of each symbol is 16.67 us.
The format of a PUCCH (Physical Uplink Control Channel) of an Uplink subframe is divided into six formats, format 1a, format 1b, format 2a, and format2b, where:
format 1b is used for transmitting ACK/NACK information of 2-bit double code word streams, and each code word stream corresponds to 1-bit ACK/NACK information;
the format2 is used for transmitting Channel Quality Indicator (CQI)/PMI and RI information;
the format 2a is used for transmitting CQI/PMI and RI information and single code word stream ACK/NACK information;
the format2b is used for transmitting CQI/PMI and RI information and double code word stream ACK/NACK information;
format 2a and format2b are used for a scenario where the cyclic prefix is a normal cyclic prefix.
The channel structures of format 1, format 1a and format 1b are the same, format 1 multiplies a fixed modulation symbol 1 by a data symbol, and whether SR information is transmitted or not is transmitted according to the existence of the format 1 channel; format 1a multiplies a BPSK symbol by a data symbol, and transmits single code word stream ACK/NACK information through the BPSK symbol; format 1b multiplies a QPSK symbol by the data symbol, and transmits the dual-codeword stream ACK/NACK information through the QPSK symbol; the channel structures of format2, format 2a and format2b are the same, format2 transmits CQI information on data symbols, and no information is sent on pilot (reference signal) symbols; format 2a transmits CQI information on data symbols, multiplies pilot (reference signal) symbols by one BPSK symbol, and transmits single codeword stream ACK/NACK information through the BPSK symbols; format2b transmits CQI information on data symbols, multiplies pilot (reference signal) symbols by one QPSK symbol, and transmits dual codeword stream ACK/NACK information through the QPSK symbols.
2-bit information for PUCCH format 1b transmission is defined as b (0) and b (1).
In a radio frame of a tdd system, there are multiple configurations of uplink and Downlink timeslot ratios, as shown in table 1, a User Equipment (UE) should feedback response information (also referred to as acknowledgement information) ACK · (correct acknowledgement)/NACK (Non-acknowledgement) of PDSCH (Physical Downlink Shared Channel) data in a Downlink subframe n in an uplink subframe PUCCH of a subframe n + k (k >3) (n represents a subframe number), and a Channel index of the uplink subframe PUCCH implicitly indicates a subframe number of Downlink data and a sequence number of a minimum CCE (Control Channel Element) where a corresponding PDCCH Channel (Physical Downlink Control Channel) is located by sending the subframe number of the Downlink data. Therefore, a scene that the ACK/NACK information of a plurality of downlink subframes is fed back exists on one uplink subframe, and the specific situation of the ACK/NACK information of the downlink subframes fed back by each uplink subframe under various configurations is shown in table 2.
TABLE 1 LTE TDD uplink and downlink ratio configuration
Wherein D represents a downlink subframe, U represents an uplink subframe, and S represents a special subframe;
TABLE 2 number of downlink subframes corresponding to when acknowledgement information is fed back to uplink subframe
The time division duplex system has two feedback methods of response information because of the scene configuration that downlink subframes are more than uplink subframes and the condition that the response information of a plurality of downlink subframes is fed back in the same uplink subframe. These two methods are the binding and multiplexing feedback methods, respectively. The bundling method is to perform an and operation on ACK/NACK information of multiple downlink subframes according to a code stream (transport block) sequence number (as long as an acknowledgment message corresponding to a PDSCH of one downlink subframe is NACK, the result is NACK, PDSCH data of all downlink subframes of the user needs to be retransmitted, and only if acknowledgment messages corresponding to PDSCHs of all downlink subframes are ACK, the result is ACK, which indicates that the PDSCHs of all downlink subframes are correctly received), and then, return an ACK/NACK information, that is, the result of the and operation. The multiplexing feedback mode refers to that the terminal respectively returns the ACK/NACK information of each subframe to the base station.
In a time division duplex system, a Downlink Allocation Index (DAI) with 2 bits is contained in a Downlink scheduling signaling, and the value of the DAI
As shown in table 3, the DAI value of each scheduled PDCCH (Physical downlink control Channel) in the feedback window (a feedback window corresponding to an uplink subframe is a set of all downlink subframes for which uplink control information needs to be fed back in the uplink subframe according to the timing relationship) is incremented by 1. The uplink scheduling signaling (carried in the last subframe sent to the UE in the feedback window) also contains a 2-bit allocation index, which indicates M downlink subframes in the feedback window (M is the size of the feedback window, i.e. the downlink subframes contained in the feedback windowMaximum 4) of PDSCH (Physical Downlink shared channel) subframes (which refer to subframes including PDSCH channels allocated to the terminal) and SPS (Semi-Persistent Scheduling) subframes which are allocated to the terminal in total. The UE selects a scrambling code sequence according to a value of a downlink assignment index indication (DAI) in the uplink scheduling signaling, scrambles the feedback response information (also referred to as ACK/NACK bits), and then transmits the scrambled response information on the uplink channel. The 4 DAI values in table 3 correspond to 1 scrambling code sequence, respectively, and the correspondence between the terminal and base station sides is the same.
TABLE 3 Downlink Allocation Index (DAI) values
| DAI high and low | Value of DAI | Number of subframes for |
| 0，0 | 1 | 1 or 5 or 9 |
| 0，1 | 2 | 2 or 6 |
| 1，0 | 3 | 3 or 7 |
| 1，1 | 4 | 0 or 4 or 8 |
In the tdd system, in addition to the ACK and NACK response information, if the UE does not correctly detect the PDCCH channel corresponding to the downlink subframe belonging to the UE, the UE will not feed back the ACK/NACK information, which is called DTX (Discontinuous Transmission). Herein, the acknowledgement information includes DTX in addition to ACK and NACK.
Herein, the response information to the PDSCH data in the downlink subframe is simply referred to as the response information to the downlink subframe
In the existing LTE TDD scheme, no method is provided for feeding back response information of a downlink subframe in a feedback window when an ACK/NACK multiplexing feedback mode is adopted, or no method is provided for feeding back response information of a downlink subframe in a feedback window when an ACK/NACK multiplexing feedback mode is adopted in a PUCCH channel. The response information of the downlink subframe herein includes response information of PDSCH channel data in the downlink subframe, and may also include response information of other downlink data that needs to be responded. The feedback method of the current downlink subframe response information is not perfect.

Detailed Description
First embodiment
In this embodiment, a specific method for feeding back downlink subframe response information in a multiplexing feedback manner with a feedback window size M of 1 is provided.
The method of the embodiment comprises the following steps:
in a first case, a UE receives an uplink scheduling signaling, where the uplink scheduling signaling indicates that a downlink subframe is scheduled to the UE in a feedback window corresponding to an uplink subframe, and when downlink data is detected on the downlink subframe, the UE determines that response information of the downlink subframe is ACK or NACK according to a downlink data receiving result, selects a scrambling code to scramble bits for transmitting the response information, and then sends the scrambled bits in an uplink channel.
And in the second case, the UE receives an uplink scheduling signaling, the uplink scheduling signaling indicates that a downlink subframe is scheduled to the UE in a feedback window corresponding to the uplink subframe, when the UE does not detect downlink data on the downlink subframe, the UE determines that response information of the downlink subframe is NACK, selects another scrambling code to scramble a bit for transmitting the response information and then transmits the bit on an uplink channel, and the selected scrambling code is different from a scrambling code adopted for scrambling the response information when the downlink data is received.
The UE can use different scrambling codes to indicate the response information under different conditions, for example, when the response information is NACK, the base station can determine whether the terminal receiving condition belongs to the first condition (the UE does not correctly decode the PDSCH) or the second condition according to the scrambling codes, without increasing the number of bits used for transmitting the response information.
When the scrambling code is specifically selected, because one scrambling code is correspondingly selected according to the value of 0-3 at present, for the condition I, the corresponding scrambling code to the DAI value in the uplink scheduling signaling can be selected in the same way as the FDDScrambling codes of, i.e. according to
Value selection of the corresponding scrambling code, for the second case above, may be employed
(mod refers to a modulo operation) selects the corresponding scrambling code. Wherein,indicating the value of DAI in uplink scheduling signaling.
In the embodiment, two corresponding scrambling codes are selected according to the calculation result of the DAI value in a determined calculation mode, so that the base station can compare only 2 scrambling codes instead of all 4 scrambling codes during descrambling, and the efficiency and the accuracy are improved. The specific calculation method makes the index interval of the 2 scrambling code sequences 1, so that the probability of false detection can be reduced.
When the UE detects a PDSCH subframe (indicating a subframe distributed by a PDSCH to the UE) scheduled by a PDCCH or a PDSCH subframe scheduled by a downlink semi-static state on a downlink subframe in a feedback window and does not receive a corresponding uplink scheduling signaling, the UE determines that response information of the PDSCH downlink subframe is ACK or NACK according to a receiving result of uplink and downlink data of the PDSCH subframe, and transmits the ACK or NACK on an uplink channel after scrambling.
The uplink channel is not limited to the PUCCH, and may be a Physical Uplink Shared Channel (PUSCH). When the PUCCH is used, the format of the PUCCH is not limited, and the response information may be transmitted.
Second embodiment
And the LTE TDD terminal acquires the parameter of the size of the downlink feedback window and transmits the response information of the downlink subframe according to the size of the feedback window. In this embodiment, a specific method for feeding back downlink subframe response information on a PUCCH channel in a multiplexing feedback manner when the feedback window size M is greater than 1 is used.
Referring to fig. 2, the method of the present embodiment includes:
in this embodiment, the scheduling signaling in the upper segment includes an uplink scheduling signaling and/or a downlink scheduling signaling. The process of this step is the same as in the prior art.
for a certain downlink subframe, the response information may determine that the response information of the downlink subframe is ACK, NACK, or DTX according to whether the terminal detects a PDCCH channel, whether PDSCH channel data is correctly received, or the like. Reference may be made in particular to existing standards.
In step 140, the terminal sets a value of a bit for transmitting the response information and an index of the PUCCH channel according to the response information combination of each downlink subframe in the feedback window and the agreed correspondence, and then transmits the bit on the PUCCH channel.
When M is greater than 1, the terminal and the base station may agree on a correspondence relationship between a combination of M pieces of response information and the bit value and PUCCH channel index used for transmitting the response information. For example, when the PUCCH channel adopts the format 1b format, a combination of each response information may correspond to one combination of a 2-bit value and a PUCCH channel index used for transmitting the response information, so as to save bit overhead for transmitting the response information.
Taking M equal to 2 as an example, when the states of the 2 downlink subframes are all ACKs, the PUCCH channel index for transmitting the response information is calculated according to the 2 nd downlink subframe sequence number in the feedback window and the sequence number of the minimum CCE where the PDCCH channel is located according to a predetermined formula (which may refer to the specification in the standard), and 2 bits, that is, b (0) and b (1), used for transmitting the response information in format 1b are set to 1; when the states of the 2 downlink subframes are ACK and NACK (or ACK and DTX), the PUCCH channel index for transmitting the response information is calculated according to the sequence number of the 1 st downlink subframe in the feedback window and the sequence number of the minimum CCE in which the PDCCH is located according to a convention formula, and b (0) and b (1) are respectively set as 0 and 1. And so on.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
