In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
A new generation mobile communication system nr (new radio) is being researched and standardized, which is one of the major points of the current 3GPP, and various problems exist in the existing communication systems.
The first embodiment is as follows:
in NR, since the number of symbols of PUCCH (Physical Uplink Control CHannel) carrying HARQ-ACK (Hybrid-ARQ-ACK) may vary, for example, the number of symbols of long PUCCH can be from 4 to 14, and repeated transmission across slots is allowed. And the resource set (including the number of symbols) of the PUCCH is configured semi-statically, the PUCCH resource specifically used by the UE (terminal) is dynamically indicated to the UE from the resource set of the PUCCH by the downlink control information of the base station, and the resource parameter of the PUCCH resource comprises a time slot identifier and the number of symbols. In NR, the resource configuration of SR (Scheduling request) is semi-static, including the period, the number of symbols, and the like, and SR is also carried in one PUCCH, except that this PUCCH is configured separately.
Thus, for a UE, its PUCCH (carrying HARQ-ACK) and SR (also carried over one PUCCH channel) may be transmitted in one slot, and there may be a situation where the symbols of the PUCCH carrying HARQ-ACK and the symbols of the PUCCH carrying SR partially overlap, and since there is no support for frequency division simultaneous transmission of two PUCCH channels in NR, for the above-mentioned partially overlapping situation, how the UE should transmit HARQ-ACK and SR; the problem may also occur in a PUCCH across slots, for example, a PUCCH (carrying HARQ-ACK) spans 4 slots, but there is an SR to transmit in the second slot of the 4 slots, and symbols of the SR partially overlap with symbols of the PUCCH.

The detailed description will now be made in conjunction with specific application scenarios.
Since the PUCCH of 5 formats is supported in NR, they are formats 0 to 4, respectively. Format 0 is used for the case that Uplink control Information UCI (Uplink control Information) is 1-2 bits, where the UCI includes HARQ-ACK (Hybrid-ARQ-ACK, Hybrid automatic repeat request acknowledgement), CSI (Channel State Information) and SR (Scheduling request), and the number of symbols is 1-2; the format 1 is used for the condition that UCI is 1-2 bits, and the number of symbols is 4-14; the format 2 is used for the condition that the UCI is more than 2 bits, and the number of symbols is 1-2; the format 3 is used for the condition that the UCI is more than 2 bits, and the number of symbols is 4-14; format 4 is used for the case that UCI is greater than 2 bits, and the number of symbols is 4-14, and UCI multiplexing of 2 or 4 UEs is supported, and only one PRB (Physical Resource Block) can be used.
For convenience of description, the problems faced will be first classified. The classification is as follows:
in Case1, the PUCCH carrying HARQ-ACK adopts format 0, the PUCCH carrying SR adopts format 0, and the symbols of the two symbols partially overlap.
In Case2, the PUCCH carrying HARQ-ACK adopts format 0, the PUCCH carrying SR adopts format 1, and the symbols of the two symbols partially overlap.
case3, the PUCCH carrying HARQ-ACK adopts format 1, the PUCCH carrying SR adopts format 0, and the two symbols partially overlap.
case4, the PUCCH carrying HARQ-ACK adopts format 1, the PUCCH carrying SR adopts format 1, and the two symbols partially overlap.
case5, the PUCCH carrying HARQ-ACK adopts format 2, 3 or 4, the PUCCH carrying SR adopts format 0, and the two symbols partially overlap.
case6, the PUCCH carrying HARQ-ACK adopts format 2, 3 or 4, the PUCCH carrying SR adopts format 1, and the two symbols partially overlap.
For the overlap case, as shown in fig. 9, it includes:
overlap mode 1: the PUCCH carrying the HARQ-ACK completely comprises the PUCCH carrying the SR;
overlap mode 2: the PUCCH carrying the SR completely comprises PUCCH carrying HARQ-ACK;
overlap mode 3: the PUCCH bearing the SR is in front and partially overlaps the PUCCH bearing the HARQ-ACK;
overlap mode 4: the PUCCH carrying the HARQ-ACK is preceding and partially overlapping the PUCCH carrying the SR.
The present embodiment will now be described in detail in different scenarios.
Scene 1:
in this scenario, neither the PUCCH carrying HARQ-ACK nor the PUCCH of SR is across slots, i.e. within a single slot.
If the symbols of the PUCCH carrying HARQ-ACK and the PUCCH carrying SR of one UE partially overlap, then:
only the resource of the SR (herein, time-frequency resource) is used in the overlapped symbol, the resource of the PUCCH in the overlapped symbol is not used, and the transmitted information is determined and transmitted using the mechanism of HARQ-ACK + SR (including the sequence allocated when HARQ-ACK is ACK or NACK + SR is "with" or "without");
in non-overlapped symbols, determining a transmitted sequence according to a mechanism of HARQ-ACK and transmitting the sequence in PUCCH symbols carrying the HARQ-ACK; or, in the non-overlapped symbols, for PUCCH symbols carrying HARQ-ACK, determining a transmitted sequence according to a mechanism of HARQ-ACK + SR and transmitting the sequence; or, in the non-overlapping symbols, for the symbols which are positioned after the SR symbol and in the PUCCH symbol carrying the HARQ-ACK, the transmitted sequence is determined according to the mechanism of HARQ-ACK + SR and is transmitted.
In non-overlapped symbols, determining a transmitted sequence according to a mechanism of HARQ-ACK + SR in PUCCH symbols carrying SR and transmitting the sequence; or in non-overlapped symbols, determining a transmitted sequence according to an SR mechanism and transmitting the sequence in PUCCH symbols carrying SRs; or, in the non-overlapping symbols, for the symbols which are positioned after the HARQ-ACK symbols and in the PUCCH symbols carrying the SR, the transmitted sequence is determined according to the mechanism of HARQ-ACK + SR and is transmitted.
The above-described PUCCH carrying SR and PUCCH for HARQ-ACK allow the use of format 0 or format 1, respectively. This delivery mechanism is well suited for the above-mentioned case1 and case3, and other cases may be used. The transmitted sequence is determined according to the HARQ-ACK + SR mechanism, which can refer to section 9.2.5 of the existing NR protocol 38.213 v1.3.0.
Since the partial overlapping of the PUCCH symbol of the HARQ-ACK and the PUCCH symbol of the SR of the same UE includes various cases, that is, cases other than the full overlapping and the non-overlapping are all partial overlapping, a specific example is given below for a part in the non-overlapping case.
Example 1:
the PUCCH symbols for HARQ-ACK are 3 ~ 13 (symbols are coded in slots, starting from 0), the symbols for SR are symbols 12 and 13, then the overlapping symbols are symbol 12 and symbol 13, and the non-overlapping symbols are 3 ~ 11. And it is assumed that the frequency domain resource of PUCCH of HARQ-ACK is different from the frequency domain resource of SR.
Thus, according to the above method, the following transmission of the PUCCH for HARQ-ACK and the PUCCH for SR can be obtained.
In symbols 12 and 13, the time-frequency resource of SR is used, and sequences (for example, when ACK and SR are transmitted, corresponding to sequence 1, when NACK and SR are transmitted, corresponding to sequence 2, when ACK and SR are transmitted, corresponding to sequence 3, and when NACK and SR are not transmitted, corresponding to sequence 4) are determined and transmitted according to the HARQ-ACK + SR mechanism. The frequency domain resources of the PUCCH in symbols 12 and 13 are not used at this time. And then determining a transmission sequence in symbols 3-11 according to a HARQ-ACK mechanism and transmitting. For example, sequence 5 corresponds to the case of transmitting ACK, and sequence 6 corresponds to the case of transmitting NACK. It is also conceivable that the sequence is determined in accordance with the HARQ-ACK + SR scheme in symbols 3 to 11 and transmitted (thus, the sequence scheme is determined in symbols 3 to 11 as in symbols 12 and 13).
Example 2:
the PUCCH symbols for HARQ-ACK are 3 ~ 12 (symbols are coded in slots, starting from 0), the symbols for SR are symbols 3 and 4, then the overlapping symbols are symbols 3 and 4, and the non-overlapping symbols are 5 ~ 12. And it is assumed that the frequency domain resource of PUCCH of HARQ-ACK is different from the frequency domain resource of SR.
Thus, according to the above method, the following transmission of the PUCCH for HARQ-ACK and the PUCCH for SR can be obtained.
In symbols 3 and 4, the time-frequency resource of SR is used, and the sequence (for example, when ACK and SR are transmitted, the sequence corresponds to sequence 1, when NACK and SR are transmitted, the sequence corresponds to sequence 2, when ACK and SR are transmitted, the sequence corresponds to sequence 3, and when NACK and SR are not transmitted, the sequence corresponds to sequence 4) is determined according to the HARQ-ACK + SR mechanism and transmitted.
The frequency domain resources of PUCCH in symbols 3 and 4 are not used at this time. And then determining a sending sequence in symbols 5-12 according to a HARQ-ACK mechanism and sending the sending sequence. For example, sequence 5 corresponds to the case of transmitting ACK, and sequence 6 corresponds to the case of transmitting NACK. It is also conceivable that the sequence is determined and transmitted in accordance with the HARQ-ACK + SR scheme in symbols 5 to 12 (thus, the sequence scheme is determined in symbols 5 to 12 as in symbols 3 and 4).
Example 3:
the PUCCH symbols for HARQ-ACK are 3 ~ 12 (symbols coded in slots, starting with 0), the symbols for SR are symbols 12 and 13, then the overlapping symbols are symbol 12, the non-overlapping symbols are 3 ~ 11, and symbol 13. And it is assumed that the frequency domain resource of PUCCH of HARQ-ACK is different from the frequency domain resource of SR.
Thus, according to the above method, the following transmission of the PUCCH for HARQ-ACK and the PUCCH for SR can be obtained.
In the symbol 12, the time-frequency resource of the SR is used, and the sequence (for example, when ACK and SR are transmitted, the sequence corresponds to sequence 1, when NACK and SR are transmitted, the sequence 2, when ACK and SR are transmitted, the sequence 3, and when NACK and SR are not transmitted, the sequence 4) is determined according to the HARQ-ACK + SR mechanism and transmitted. The SR resource in the symbol 13 may be transmitted after determining the sequence according to the HARQ-ACK + SR scheme, or in this case, the symbol 13 may be transmitted after determining the sequence according to the SR-only scheme.
The frequency domain resources of the PUCCH in symbols 12 and 13 are not used at this time. And then determining a transmission sequence in symbols 3-11 according to a HARQ-ACK mechanism and transmitting. For example, sequence 5 corresponds to the case of transmitting ACK, and sequence 6 corresponds to the case of transmitting NACK. It is also conceivable that the sequence is determined in accordance with the HARQ-ACK + SR scheme in symbols 3 to 11 and transmitted (thus, the sequence scheme is determined in symbols 3 to 11 as in symbols 12 and 13).
Example 4:
the PUCCH symbols of the SR are 3-12 (symbols coded in slots, starting with 0), the symbols of the PUCCH are symbols 3 and 4, then the overlapping symbols are symbols 3 and 4, and the non-overlapping symbols are 5-12. And it is assumed that the frequency domain resource of PUCCH of HARQ-ACK is different from the frequency domain resource of SR.
Thus, according to the above method, the following transmission of the PUCCH for HARQ-ACK and the PUCCH for SR can be obtained.
In symbols 3 and 4, the time-frequency resource of SR is used, and the sequence (for example, when ACK and SR are transmitted, the sequence corresponds to sequence 1, when NACK and SR are transmitted, the sequence corresponds to sequence 2, when ACK and SR are transmitted, the sequence corresponds to sequence 3, and when NACK and SR are not transmitted, the sequence corresponds to sequence 4) is determined according to the HARQ-ACK + SR mechanism and transmitted.
The frequency domain resources of PUCCH in symbols 3 and 4 are not used at this time. And then determining a sending sequence in symbols 5-12 according to an SR mechanism and sending. For example, when SR is "present" the sequence 5 is transmitted, and when SR is "absent" the sequence 6 is transmitted. It is also conceivable that the sequence is determined and transmitted in accordance with the HARQ-ACK + SR scheme in symbols 5 to 12 (thus, the sequence scheme is determined in symbols 5 to 12 as in symbols 3 and 4).
Scene 2:
in this scenario, both the PUCCH carrying HARQ-ACK and the PUCCH of SR are not across slots, i.e. within a single slot.
If more PUCCH symbols bearing SR, less PUCCH symbols bearing HARQ-ACK, and the symbols of the PUCCH bearing HARQ-ACK and the PUCCH bearing SR of one UE are partially overlapped, the following processing is carried out:
in the overlapped symbols, if the SR is 'none', the resource of the HARQ-ACK (time frequency resource is referred to herein), if the SR is 'available', the resource of the SR is used, and the HARQ-ACK + SR or the mechanism of the HARQ-ACK is used to determine the sequence, modulate the HARQ-ACK information on the sequence and transmit the HARQ-ACK information;
in non-overlapped symbols, determining and transmitting transmitted information according to a mechanism of HARQ-ACK in PUCCH symbols carrying the HARQ-ACK; or, in non-overlapped symbols, in PUCCH symbols bearing HARQ-ACK, determining and transmitting transmitted information according to a mechanism of HARQ-ACK + SR;
in non-overlapped symbols, determining and transmitting transmitted information according to a mechanism only with SR in PUCCH symbols carrying SR; or, in non-overlapped symbols, in PUCCH symbols carrying SR, determining information according to a mechanism of HARQ-ACK + SR and transmitting the information; or, in the non-overlapped symbols, the information is determined and transmitted according to the mechanism of HARQ-ACK + SR in the PUCCH symbols carrying the SR and in the symbols after the HARQ-ACK symbols.
The above-described PUCCH carrying SR allows the use of format 1. This delivery mechanism is well suited for the above-mentioned case2 and case4, and other cases may be used.
Scene 3:
in this scenario, both the PUCCH carrying HARQ-ACK and the PUCCH of SR are not across slots, i.e. within a single slot.
When the PUCCH carrying the HARQ-ACK and the PUCCH symbol carrying the SR of one UE are partially overlapped, the SR is concatenated behind the HARQ-ACK as bit information and then is sent in a coding mode, and the resource of the PUCCH carrying the HARQ-ACK is used. Specifically, HARQ-ACK + SR is transmitted using ACK resources
Further, if it is not determined whether the SR is "present" or "absent" at the time of signal formation or transmission of the PUCCH of HARQ-ACK, improvement is required for the above manner.
For example, the improvement is that the PUCCH carrying the HARQ-ACK and the PUCCH carrying the SR of one UE are partially overlapped, the starting symbols of the HARQ-ACK and the SR are aligned, or when the starting symbol of the SR is later than the starting symbol duration of the HARQ-ACK by T, the SR is concatenated behind the HARQ-ACK as bit information and then is coded and transmitted, and the resource of the PUCCH carrying the HARQ-ACK is used. Wherein, the role of T is to assume that the time duration of SR no later than the HARQ-ACK starting symbol is T when forming or transmitting HARQ-ACK, and it is considered that the state of SR is "present" or "absent". T can be determined according to UE capabilities.
This delivery mechanism is well suited for the above-mentioned case5 and case6, and other cases may be used.
Scene 4:
in this scenario, the PUCCH carrying HARQ-ACK is slot-across, i.e. one PUCCH is repeatedly transmitted in multiple slots (which may be continuous or discontinuous).
The PUCCH carrying HARQ-ACK at one UE spans the slot (the PUCCH format at this time may be format 1, 3 or 4), and the PUCCH symbol carrying SR partially overlaps in one slot. Then it can be processed in one of the following ways, as shown in fig. 10:
selecting 10-a, and processing in all slots of a PUCCH carrying HARQ-ACK, specifically: in the overlapped symbol (slot 2), HARQ-ACK and SR are transmitted by adopting the mode of scenes 1 to 3, and in other slots (slots 1, 3 and 4) except the slot (slot 2) to which the overlapped symbol belongs, the SR is transmitted by using the time domain resource of the HARQ-ACK.
Selecting 10-b, starting from the slot where the partial overlap occurs (including), processing the slot of the subsequent PUCCH carrying HARQ-ACK, specifically, in the overlapping symbol (slot 2), transmitting HARQ-ACK and SR by adopting a scene 1 to 3 manner, in the subsequent slot (slots 3 and 4) excluding the slot to which the overlapping symbol belongs (slot 2), only carrying HARQ-ACK in the remaining slots (slot 1).
Selecting 10-c, and only including HARQ-ACK and SR in the slot where the partial overlap occurs, specifically, in the overlapped symbol (slot 2), transmitting HARQ-ACK and SR by adopting a mode of scenes 1 to 3, and carrying HARQ-ACK in the rest slots (slots 1, 3 and 4).
The above processing in the slot of the PUCCH with SR and HARQ-ACK may adopt a specific case in scenario 1, 2, or 3.
Scene 5:
in this scenario, the PUCCH carrying HARQ-ACK is slot-across, i.e. one PUCCH is repeatedly transmitted in multiple slots (which may be continuous or discontinuous).
For the PUCCH across slots, since only the number of symbols occupied by the PUCCH in the first slot and the starting symbol are determined, the subsequent slots are derived according to a predetermined condition, for example, when the same (symbol position and number) symbols available for the PUCCH exist in the subsequent slots, the slot is selected as the subsequent slot of the PUCCH. In combination with this rule, in order to avoid the partial overlapping of the PUCCH and SR symbol across slots, the slot where the SR and the PUCCH symbol carrying HARQ-ACK partially overlap will not be used as the subsequent slot of the PUCCH carrying HARQ-ACK when the subsequent slot is selected. That is, if there is a partial overlap of symbols of PUCCH and SR carrying HARQ-ACK in a slot, the slot is not used as a subsequent slot.
Optionally, as shown in fig. 2, the data transmission management apparatus 2 provided in this embodiment includes:
a determining module 21, configured to determine a first resource parameter for transmitting the first data and a second resource parameter for transmitting the second data;
and the optimizing module 22 is configured to optimize the first resource parameter and the second resource parameter.
Optionally, the optimization module 22 is configured to: and when the first physical channel time domain resource corresponding to the first resource parameter and the second physical channel time domain resource corresponding to the second resource parameter are partially overlapped, transmitting the first data and the second data in the overlapped physical channel time domain resource by adopting a preset transmission mode.
Example two:
at present, a CSI (Channel State Information) report is divided into two parts in some cases, wherein the CSI of the first part is determined by a certain bit number (that is, the base station and the UE know the bit number), and the CSI of the second part is dynamically determined (the UE knows the bit number, and the base station does not know the bit number). For example, when CSI reports are uploaded to the base station via the PUSCH of the UE, and when sub-band CSI reports are fed back via a long PUCCH format (e.g., format 3,4), the CSI reports are divided into two parts. Perhaps in other subsequent cases, the CSI report is also required to be divided into two parts, but the number of CSI report bits of the first part is determined for the base station and the number of CSI report bits of the second part is not determined for the base station. The first part CSI report indirectly or directly carries the bit number of the second part CSI report, and the base station acquires the bit number of the second part CSI report after receiving the first part CSI report.
However, if two parts of CSI reports and HARQ-ACK and/or SR are to be transmitted simultaneously through one PUCCH or PUSCH channel, how to transmit these data is to ensure that the base station can determine at least a part of the data.
In order to solve the above problem, referring to fig. 3, the data transmission management method provided in this embodiment includes the following steps at the terminal side:
s301: determining at least two data to be transmitted;
s302: and simultaneously transmitting at least two data through the same physical channel according to a preset sequencing mode.
Referring to fig. 4, the data transmission management method provided in this embodiment includes the following steps at the base station side:
s401: receiving at least two data transmitted by a terminal through the same physical channel;
s402: and decomposing at least two data according to a preset sorting mode to determine each data.
Optionally, the at least two data include a CSI (Channel State Information) report and at least one of a HARQ-ACK (Hybrid-ARQ-ACK, Hybrid automatic repeat request acknowledgement code) and a SR (Scheduling request); the CSI report comprises a first part CSI report and a second part CSI report, and the preset ordering mode comprises at least one of the following modes:
the first partial CSI report is followed by a HARQ-ACK, which is followed by a second partial CSI report;
the first partial CSI report is followed by an SR, which is followed by a second partial CSI report;
the first partial CSI report is followed by an SR, the SR is followed by a HARQ-ACK, and the HARQ-ACK is followed by a second partial CSI report;
the first partial CSI report is followed by a HARQ-ACK, which is followed by an SR, which is followed by a second partial CSI report.
Specifically, in order to solve how the CSI report and the HARQ-ACK and/or SR divided into two parts are transmitted simultaneously through one PUCCH or PUSCH channel, such a scheme may be adopted:
if HARQ-ACK (or SR, here SR refers to description by bit) and CSI report of a UE are transmitted simultaneously, and the CSI report is divided into two parts, the base station and the UE agree on the above signaling joint coding, and the order principle of their bits is according to one of the following ways:
mode 1, the first partial CSI report bit is followed by the HARQ-ACK bit, which is followed by the second partial CSI report bit.
Mode 2, the first partial CSI report bit is followed by an SR bit, which is followed by a second partial CSI report bit.
Mode 3, the first partial CSI report bit is followed by an SR bit, the SR bit is followed by an HARQ-ACK bit, and the HARQ-ACK bit is followed by a second partial CSI report bit.
Mode 4, the first partial CSI report bit is followed by a HARQ-ACK bit, the HARQ-ACK bit is followed by a SR bit, and the SR bit is followed by a second partial CSI report bit.
Mode 4 serves as a complementary principle.
The UE performs coded transmission on the bits of the HARQ-ACK, SR and/or CSI report according to the above-described principle. And the base station decodes the HARQ-ACK, SR and/or CSI report sent by the receiving UE according to the principle.
After the above manner is adopted, since the number of bits of the CSI report of the first part is always determined, the number of bits of the HARQ-ACK is uncertain (missed detection due to a possibility of dynamic codebook), and the number of bits of the CSI report of the second part is uncertain, placing the first part of CSI report bits at the top is beneficial to utilizing the block code characteristic, and in case of uncertain or erroneous subsequent bits, the first part of CSI report is still correctly decoded.
Example three:
now, it is defined in NR that there are two types of fallback DCI and non-fallback DCI in the uplink DCI (Downlink control information), where it is further defined that the uplink fallback DCI does not include 2-bit uplink DAI (Downlink assignment index) information.
When HARQ-ACKs of multiple downlink TBs (transport blocks) of the same UE are multiplexed and transmitted through a PUSCH channel of the UE, but what manner is used for scheduling the PUSCH, which uplink control information DCI is used, and a codebook determination problem that corresponds to the HARQ-ACK are all technical problems that need to be solved in any field.
In order to solve the above problem, referring to fig. 5, the data transmission management method provided in this embodiment includes the following steps at the terminal side:

Optionally, the determining the codebook forming method of the self data includes:

Referring to fig. 6, the data transmission management method provided in this embodiment includes the following steps at the base station side:
s601: determining a DCI type;
s602: and determining a scheduling mode and/or a codebook forming mode of the terminal data.
Optionally, determining the scheduling manner of the terminal data includes at least one of the following manners:
in the public search space scheduling, only public data is scheduled by using uplink fallback DCI;
for a terminal configured with a dynamic codebook, when HARQ-ACK of a plurality of downlink transmission blocks of the terminal are multiplexed and transmitted through an uplink physical shared channel of the terminal, the uplink physical shared channel is not scheduled by using uplink fallback DCI;
for a terminal configured with a dynamic codebook, when HARQ-ACK of a plurality of downlink transmission blocks of the terminal are multiplexed and transmitted through an uplink physical shared channel of the terminal, the uplink physical shared channel is not scheduled in a public search space by using uplink fallback DCI;
for a terminal configured with a dynamic codebook, when HARQ-ACK of a plurality of Downlink transmission blocks of the terminal are multiplexed and transmitted through an uplink physical shared channel of the terminal, uplink fallback DCI carrying uplink DAI (Downlink assignment index) information is used for scheduling the uplink physical shared channel;
for the terminal configured with the dynamic codebook, when HARQ-ACK of a plurality of downlink transmission blocks of the terminal are multiplexed and transmitted through an uplink physical shared channel of the terminal and a transmission block scheduled by downlink fallback DCI exists in the plurality of downlink transmission blocks, the uplink physical shared channel is not scheduled by the uplink fallback DCI.
Optionally, the determining the codebook forming manner of the terminal data includes:
for a terminal configured with a dynamic codebook, when HARQ-ACK of a plurality of downlink transmission blocks of the terminal are multiplexed and transmitted through an uplink physical shared channel of the terminal, if uplink fallback DCI is used for scheduling the uplink physical shared channel transmission, the terminal is considered to switch the dynamic codebook mode into a semi-static codebook mode to form HARQ-ACK multiplexing.
For example, the UE configures a dynamic codebook, for the UE1, TBs 1 to TB4 are scheduled (4 TBs are only one representative, and these TBs may be from the same carrier, or from different subbands of the same carrier, or from different carriers), corresponding HARQ q-ACKs 1 to HARQ-ACKs 4 are multiplexed and encoded together and transmitted through the PUSCH channel of the UE, but how the PUSCH is scheduled and how the corresponding codebook (total number of bits of multiplexed HARQ-ACKs) is determined, this embodiment proposes the following options:
selecting 1:
the base station uses the uplink fallback DCI, and if the uplink fallback DCI is sent in the common search space, the uplink fallback DCI does not schedule data at the UE level (except for the message 4 of random access), that is, the uplink fallback DCI can only schedule common data (e.g., data at the cell level) when the base station sends the uplink fallback DCI in the common search space. It can also be understood that if the UE detects that its PUSCH is scheduled by an uplink fallback DCI, and the uplink fallback DCI is in the common search space, the UE considers that there is an error and does not perform processing.
Selecting 2:
for a UE configured with a dynamic codebook, HARQ-ACKs of multiple downlink TBs are multiplexed and transmitted via a PUSCH of the UE, and the UE does not expect the PUSCH to be scheduled via an uplink fallback DCI (that is, uplink non-fallback DCI can be used because there are at least 2 DCI formats in the uplink, one is a fallback DCI format, and the other is a non-fallback DCI format, the same below); or, when the base station multiplexes HARQ-ACKs of a plurality of downlink TBs for the UE configured with the dynamic codebook and transmits the multiplexed HARQ-ACKs through one PUSCH of the UE, the base station does not schedule the PUSCH using the uplink fallback DCI. It can also be understood that: if the UE is configured with the dynamic codebook, the HARQ-ACK of a plurality of downlink TBs is multiplexed and transmitted through one PUSCH of the UE, and if the UE detects that the PUSCH is scheduled by one uplink fallback DCI, the UE considers that an error occurs and does not process the error.
Selecting 3:
for a UE configured with a dynamic codebook, HARQ-ACK of a plurality of downlink TBs are multiplexed and transmitted through one PUSCH of the UE, and the UE does not expect that the PUSCH is scheduled through uplink fallback DCI of a common search space; or, when the base station multiplexes the HARQ-ACKs of the plurality of downlink TBs for the UE configured with the dynamic codebook and transmits the multiplexed HARQ-ACKs through one PUSCH of the UE, the base station does not use the uplink fallback DCI to schedule the PUSCH in the common search space. It can also be understood that: if the UE is configured with the dynamic codebook, HARQ-ACK of a plurality of downlink TBs are multiplexed and transmitted through one PUSCH of the UE, and if the UE detects that the PUSCH is scheduled to pass through uplink fallback DCI of the common search space, the UE considers that the error occurs and does not process the error.
Selecting 4:
for the UE configured with the dynamic codebook, the HARQ-ACK of a plurality of downlink TBs are multiplexed and transmitted through one PUSCH of the UE, and if the PUSCH is scheduled by using fallback DCI, the UE expects the fallback DCI to be transmitted through a UE-dedicated search space and carry uplink DAI information; or, when the base station multiplexes the HARQ-ACKs of the multiple downlink TBs for the UE configured with the dynamic codebook and transmits the multiplexed HARQ-ACKs through one PUSCH of the UE, the base station uses an uplink fallback DCI to schedule the PUSCH in the UE-level dedicated search space, and the uplink fallback DCI carries an uplink DAI.
Selecting 5:
for the UE configured with the dynamic codebook, the HARQ-ACK of the plurality of downlink TBs are multiplexed and transmitted through one PUSCH of the UE, and if the plurality of downlink TBs have a TB scheduled by the downlink fallback DCI, the UE does not expect the PUSCH to be scheduled through the uplink fallback DCI; or, when the base station multiplexes HARQ-ACKs of multiple downlink TBs for the UE configured with the dynamic codebook and transmits the multiplexed HARQ-ACKs through one PUSCH of the UE, if the base station schedules at least one of the multiple TBs by using the downlink fallback DCI, the base station does not schedule the PUSCH by using the uplink fallback DCI.
Selecting 6:
for the UE configured with the dynamic codebook, the HARQ-ACKs of a plurality of downlink TBs are multiplexed and transmitted through one PUSCH of the UE, and if the UE detects that the PUSCH is scheduled to pass through an uplink fallback DCI (the uplink fallback DCI), the UE switches the configured dynamic codebook mode into a semi-static codebook mode to form HARQ-ACK multiplexing; or, when the base station multiplexes the HARQ-ACKs of the multiple downlink TBs for the UE configured with the dynamic codebook and transmits the multiplexed HARQ-ACKs through one PUSCH of the UE, if the base station schedules the PUSCH by using the uplink fallback DCI, the base station considers that the UE switches the dynamic codebook mode to the semi-static mode to form HARQ-ACK multiplexing and feeds back the HARQ-ACK multiplexing.
The selection 6 is to switch the dynamic codebook configured for the UE to a semi-static codebook through a trigger condition, where the trigger condition is whether the PUSCH is scheduled by the uplink fallback DCI, and actually, the trigger condition is mainly that there is no uplink DAI in the fallback DCI, that is, the trigger condition may also be understood as whether the PUSCH is scheduled by a DCI not carrying the uplink DAI. And if the DCI for scheduling the PUSCH carries the uplink DAI, the UE and the base station understand that HARQ-ACK multiplexing is continuously formed and fed back according to the dynamic codebook mode.

Example five:
the present embodiment solves the problem of how to determine the base sequence (also referred to as sequence group or group sequence) of the uplink control channel (PUCCH).
The base station and the UE agree to determine the base sequence of the PUCCH by one of the following ways:
in the mode 1, the base station and the UE appoint, and the base sequence of the PUCCH is determined by using the time slot number and the subframe number of the PUCCH. Thus, the identification sequence is used for all symbols of the PUCCH. And the UE applies the determined base sequence to the PUCCH to transmit the PUCCH. And the base station receives the PUCCH and detects the base sequence according to the reverse process.
For example, the UE and the base station determine the base sequence according to the following equation:
Figure BDA0001546798690000221
where u in mode 1 denotes the index of the base sequence, Q is equal to the total number of base sequences, fssThe definition is determined by the cell physical ID, nsSb is the number of the slot, and Sb is the subframe number; c (i) is a pseudo-random sequence with an initial value of
Figure BDA0001546798690000222
Is the cell physical ID of the cell, or a virtual cell physical ID configured by higher layers. N, K are constants.
And 2, the base station and the UE appoint, and the base sequence of the PUCCH is determined by using the slot number, the subframe number and the OFDM symbol index of the PUCCH. The OFDM symbol index is the number of the OFDM symbol in the PUCCH, or the OFDM symbol index is the number of the OFDM symbol in the slot in which the OFDM symbol is located. Thus, the determined base sequence is changed according to the OFDM symbol of the PUCCH (the change is also referred to as base sequence frequency hopping according to the symbol). And the UE applies the determined base sequence to the PUCCH to transmit the PUCCH. And the base station receives the PUCCH and detects the base sequence according to the reverse process.
For example, the UE and the base station determine the base sequence according to the following equation:
Figure BDA0001546798690000223
wherein, in mode 2, u represents the index of the base sequence, Q is equal to the total number of base sequences, fssThe definition is determined by the cell physical ID, nsIs the number of the slot, l is the symbol index of the symbol in the slot, Sb is the subframe number, c (i) is a pseudo-random sequence with an initial value of
Figure BDA0001546798690000231
Is the cell physical ID of the cell, or a virtual cell physical ID configured by higher layers. N, K and H are constants.
And 3, the base station and the UE appoint to determine the base sequence by using the slot number, the subframe number and the number of each frequency hopping of the PUCCH. Thus, the determined base sequence changes for each hop (the change is also referred to herein as the base sequence hopping for each hop). Each hop number may be the number of each hop in turn within the slot (e.g., PUCCH hops 1 time within the slot, the first hop is numbered 0, and the second hop is numbered 1), or each hop number may be the first OFDM symbol index of each hop. The OFDM symbol index here is the number of the OFDM symbol in the PUCCH, or the OFDM symbol index is the number of the OFDM symbol in the slot in which the OFDM symbol is located. If the PUCCH is not frequency-hopped, the base sequence of the PUCCH can be determined in a mode of determining the base sequence for the first frequency hopping of the PUCCH, or the PUCCH can be assumed to be frequency-hopped, then the base sequence of each frequency hopping is determined, and the determined base sequence is used on the symbol of each frequency hopping when the corresponding assumption frequency hopping is carried out. And the UE applies the determined base sequence to the PUCCH to transmit the PUCCH. And the base station receives the PUCCH and detects the base sequence according to the reverse process.
For example, the UE and the base station determine the base sequence according to the following equation:
Figure BDA0001546798690000232
wherein, in mode 3, u represents the index of the base sequence, Q is equal to the total number of base sequences, fssThe definition is determined by the cell physical ID, nsIs the number of the time slot, lhopIs the number of each hop, Sb is the subframe number, c (i) is a pseudo-random sequence whose initial value is

Is the cell physical ID of the cell, or a virtual cell physical ID configured by higher layers. N, K and H are constants.
