Technical Field

Background

At present, in an NR (New Radio, New air interface) communication system, Uplink control Information HARQ-ACK (Hybrid Automatic Repeat request Acknowledgement) and CSI (Channel State Information) are supported to be multiplexed with data on PUSCH (Physical Uplink Shared Channel).

Currently, multi-slot PUCCH (Physical Uplink Control Channel) and multi-slot PUSCH transmission are supported in NR, and when a single-slot PUCCH and a single-slot PUSCH collide, the current conclusion is that if starting symbols of the PUCCH and the PUSCH are the same in the colliding slot, Uplink Control information is multiplexed in the PUSCH for transmission, and the PUCCH is not transmitted. Multi-slot repetition transmission of PUCCH and PUSCH is currently supported in 5G (5th-Generation, fifth Generation mobile communication technology), but simultaneous transmission of PUCCH and PUSCH is not supported. For the case of multi-slot PUCCH and PUSCH collisions, no solution is currently defined.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

Some concepts mentioned in the embodiments of the present invention are first explained as follows.

When the uplink control information is multiplexed on the PUSCH, an explicit mapping rule has been defined, for example: the HARQ-ACK is mapped sequentially according to a mode of first frequency domain and then time domain after a first DMRS (Demodulation Reference Signal) symbol; mapping the CSI part 1 and the CSI part 2 from a first available RE (Resource Element) Resource according to a frequency domain first and time domain later mode; if RE resources occupied by UCI (Uplink Control Information) do not occupy an entire OFDM (Orthogonal Frequency Division Multiplexing) symbol or RE resources occupied by UCI are more than one symbol but RE resources on all PUSCH bandwidths cannot be occupied on the last symbol, then discrete mapping is averaged over the Frequency domain, e.g., when the resources of UCI do not occupy one symbol, the Frequency domain interval is the number of REs available on the symbol/the number of remaining un-mapped UCI symbols and rounded down. If the bit number of the HARQ-ACK is 0 or 1 or 2, a part of resources are reserved, the CSI part 1 is not mapped on the reserved RE resources, and the CSI part 1 is mainly prevented from being punctured by the HARQ-ACK.

The invention provides an information transmission method, a receiving method, a terminal and network equipment, aiming at the problems that in the prior art, when the conflict between a multi-slot PUCCH and a PUSCH is not defined, how to transmit the PUCCH and the PUSCH causes incomplete communication flow and can not ensure the communication reliability.

As shown in fig. 1, an information transmission method according to an embodiment of the present invention is applied to a terminal, and includes:

and step 11, when the transmission of the target physical uplink control channel PUCCH and the physical uplink shared channel PUSCH conflicts, multiplexing the uplink control information in the target PUCCH on the PUSCH for transmission in the time slot where the conflict happens, or discarding the PUSCH for only transmitting the uplink control information in the target PUCCH.

It should be noted that, in one slot, at least one OFDM symbol overlaps with the target PUCCH and the PUSCH in the time domain, which is referred to as collision of the target PUCCH and the PUSCH, that is, collision of transmission of the target PUCCH and the PUSCH occurs. For the case that simultaneous transmission of PUCCH and PUSCH is not supported and the case that simultaneous transmission of PUCCH and PUSCH is not used in network device configuration, how to solve the collision problem of the target PUCCH and PUSCH in the embodiment of the present invention needs to be considered.

It should be noted that, in the embodiment of the present invention, the target PUCCH belongs to a multi-slot PUCCH, and the multi-slot PUCCH occupies at least two slots for transmission.

In the embodiment of the invention, when the transmission of the multi-slot PUCCH and the PUSCH conflicts, in the time slot where the conflict happens, the uplink control information in the multi-slot PUCCH is multiplexed on the PUSCH for transmission, or the PUSCH is discarded and only the uplink control information in the target PUCCH is transmitted, so that the normal transmission of the uplink control information can be ensured when the conflict happens, and the condition that the network communication is interrupted because the transmission of the multi-slot PUCCH and the PUSCH conflicts can not occur.

Specifically, the implementation manner of step 11 in the embodiment of the present invention is:

In a specific implementation manner of step 11, the transmission conflict is compared with a preset conflict condition, if the transmission conflict meets the preset conflict condition, a manner of multiplexing the uplink control information in the target PUCCH on the PUSCH for transmission is adopted in a time slot where the conflict occurs, and if the transmission conflict does not meet the preset conflict condition, a manner of discarding the PUSCH and transmitting only the uplink control information in the target PUCCH is adopted.

Specifically, two preset conflict conditions are set in the embodiment of the present invention, and each preset conflict condition is specifically described below.

The first, preset conflict condition includes all of the following conditions:

It should be noted that, in this case, 4 conditions must be satisfied to determine that the transmission conflict meets the preset conflict condition, and if one condition is not satisfied, it is also determined that the transmission conflict does not meet the preset conflict condition.

For example, when the multi-slot PUCCH and the single-slot PUSCH collide with each other, the network device discards the PUSCH and only transmits the uplink control information in the multi-slot PUCCH when transmitting because the collision does not meet the preset collision condition.

For example, when the multi-slot PUCCH and the multi-slot PUSCH collide, if the starting position of the multi-slot PUCCH is equal to or later than the starting position of the multi-slot PUSCH in terms of time and the ending position of the multi-slot PUCCH is equal to or earlier than the ending position of the multi-slot PUSCH in terms of time, and the multi-slot PUCCH collides with the PUSCH in each occupied slot and the starting symbol is the same, because the preset collision condition is met, the network device multiplexes the uplink control information in the multi-slot PUCCH on the PUSCH to transmit, and does not transmit the multi-slot PUCCH.

It should be noted that, when the first preset collision condition is adopted to control information transmission, it can be ensured that the number of RE resources occupied by uplink control information in each occupied time slot of multi-slot PUCCH transmission is the same, so that multiple times of received information can be directly merged when the base station receives decoding, and the implementation is relatively simple.

The second, preset conflict condition is: and in at least one slot where the target PUCCH and the PUSCH collide, the transmission starting symbols of the target PUCCH and the PUSCH are the same.

It should be noted that, under such preset collision condition, the PUSCH colliding with the multi-slot PUCCH occupies at least one slot for transmission, that is, the PUSCH colliding with the multi-slot PUCCH may be a single-slot PUSCH (the PUSCH occupies one slot for transmission), or a multi-slot PUSCH (the PUSCH occupies at least two slots for transmission, that is, the PUSCH needs to be repeatedly transmitted).

For example, a multi-slot PUCCH and a single-slot PUSCH (or a multi-slot PUSCH) collide, and in a colliding slot, if starting symbols of the multi-slot PUCCH and the PUSCH are the same, when the network device performs transmission, the network device multiplexes uplink control information in the multi-slot PUCCH on the PUSCH to perform transmission, and does not transmit the multi-slot PUCCH; otherwise, when the network equipment transmits, the PUSCH is discarded, and only the uplink control information in the target PUCCH is transmitted.

It should be noted that, when the second preset collision condition is adopted to control information transmission, the situation of discarding PUSCH transmission can be reduced, and the disadvantage is that the number of RE resources occupied by uplink control information received by the network device in different time slots is different, and when decoding, multiple pieces of received information with different coding lengths need to be merged, so that implementation is complicated.

Specifically, in this case, for the target PUCCH, the coding rate of the uplink control information is determined according to the resource element resource available for uplink control information transmission in the first transmission slot of the target PUCCH, and in the repeated slot of the target PUCCH, the uplink control information is transmitted by rate matching based on the coding rate of the first transmission slot of the target PUCCH.

It should be noted that, after determining the coding rate of the uplink control information according to the resource element resource available for uplink control information transmission in the first transmission slot of the target PUCCH, determining the number of coding bits according to the coding rate, and then performing rate matching (where the rate matching is implemented in a bit repetition or bit puncturing manner) in the repeated slot of the target PUCCH according to the number of coding bits to implement transmission of the uplink control information.

The embodiment of the present invention is described by taking an example of a terminal implementing uplink control information transmission, and it should be noted that when a network device receives uplink control information, the network device also receives the uplink control information in the same manner, that is, how the terminal transmits the uplink control information, how the network device receives the uplink control information, that is, the preset collision conditions adopted by the terminal and the network device are the same, that is, when the terminal performs transmission control of the uplink control information by using the first preset collision condition, the network device also knows the preset collision condition adopted by the terminal, and receives the uplink control information in the same manner as the preset collision condition of the terminal.

The following describes specific implementations of embodiments of the present invention in different application scenarios.

Firstly, assuming that a base station configures a terminal with a repetition number of a multi-slot PUCCH being 4 through Radio Resource Control (RRC) signaling, and the base station does not perform semi-static uplink and downlink allocation or has enough uplink symbols for the PUCCH in a PUCCH repeated slot according to configuration information, the multi-slot PUCCH performs repeated transmission in consecutive slots n +3 to n +6, and all transmissions start from a first symbol in the slot, which is described below as an example for collision situations of different multi-slot PUCCHs and PUSCHs.

In case a-1, as shown in fig. 2, assuming that the base station schedules PUSCH transmission in time slot n +3, in this case, the transmission control of the uplink control information is performed by using a first preset collision condition, and the PUSCH transmission is discarded; the terminal transmits only the PUCCH in slot n +3 to slot n + 6. Under the condition, the number of RE resources occupied by the uplink control information in the time slot n +3 to the time slot n +6 can be ensured to be the same, and the base station can directly merge the information received for multiple times when receiving and decoding, so that the method is simple to realize.

In fig. 2, a diagonal filled box indicates transmission of PUCCH, a vertical filled box indicates transmission of PUSCH, and a cross indicates PUSCH in which the slot is not transmitted.

Case A-2: as shown in fig. 3, assuming that the base station schedules PUSCH transmission in slot n +3 and PUSCH transmission starts from the first symbol in slot n +3, in this case, a second preset collision condition is adopted to perform transmission control on uplink control information, and uplink control information is multiplexed on PUSCH and transmitted in slot n +3, and PUCCH is not transmitted; the terminal transmits only the PUCCH in slot n +4 to slot n + 6. In this case, the situation of discarding the PUSCH transmission in the slot n +3 can be avoided, but the base station needs to combine the received information with different coding lengths in the slot n +3 to the slot n +6 when receiving and decoding, which is more complex to implement.

Further, when encoding the uplink control information transmitted in the PUCCH, it is necessary to determine a corresponding encoding code rate. For multi-slot PUCCH transmission, in order to ensure correct HARQ combining during reception, it is necessary to ensure that the same coding rate is used for coding uplink control information in different slots. Considering that we cannot predict in advance whether each subsequent slot will collide with the PUSCH for the multi-slot PUCCH, it is necessary to determine its coding rate based on the first transmission slot of the multi-slot PUCCH. For example, in the time slot n +3, since the uplink control information is multiplexed on the PUSCH for transmission, the number of RE resources occupied by UCI transmission needs to be determined according to information bits transmitted on the PUSCH, and assuming that UCI is HARQ-ACK information, the corresponding bit number is a, and the number of B RE resources occupied on the PUSCH, the code rate of HARQ-ACK is a/(B × m), where m is the modulation order, and B × m coded bits are obtained after coding. In the subsequent repetition time slots n +4, n +5 and n +6, no matter how many actual transmission resource REs are, B × m code bits can be repeated or punctured to obtain the corresponding number of code bits. Assuming that the number of the actual transmission resources RE is C, if (C × m) > (B × m), repeating B × m coded bits to obtain C × m coded bits, and if (C × m) < (B × m), puncturing B × m coded bits, that is, discarding the redundant coded bits to finally obtain C × m coded bits.

In fig. 3, diagonal filled boxes indicate transmission of PUCCH, vertical filled boxes indicate transmission of PUSCH, and cross lines indicate that PUCCH in the slot is not transmitted.

Case B: as shown in fig. 4, assuming that the base station schedules the repeated transmission of the multi-slot PUSCH in the slot n +3 to the slot n +6, the transmission of the PUSCH does not conflict with the uplink and downlink transmission directions configured semi-statically by the base station, and the multi-slot PUSCH starts to transmit from the first symbol in the slot, the terminal multiplexes the uplink control information on the PUSCH in the slot n +3 to the slot n +6 for transmission, and does not transmit the PUCCH; it should be noted that, in this case, the same transmission effect can be achieved by using the first preset collision condition or the second preset collision condition for the transmission control of the uplink control information, that is, no matter how many symbols are occupied by the PUCCH and PUSCH transmission in one slot, as long as the PUCCH and PUSCH transmission start symbols in one slot are the same, the uplink control information can be multiplexed on the PUSCH for transmission.

In fig. 4, diagonal filled boxes indicate transmission of PUCCH, vertical filled boxes indicate transmission of PUSCH, and cross lines indicate that PUCCH in the slot is not transmitted.

Case C: as shown in fig. 5, assuming that the base station schedules the repeated transmission of the multi-slot PUSCH in the time slot n +3 to the time slot n +6, the transmission of the PUSCH does not conflict with the uplink and downlink transmission directions configured semi-statically by the base station, and the multi-slot PUSCH starts to transmit from the third symbol in the time slot, the terminal discards the PUSCH in the time slot n +3 to the time slot n +6, and only transmits the PUCCH; it should be noted that, in this case, the same transmission effect can be achieved by using the first preset collision condition or the second preset collision condition to perform the transmission control of the uplink control information.

In fig. 5, the hatched filled boxes indicate transmission of PUCCH, the vertical filled boxes indicate transmission of PUSCH, and the cross lines indicate that PUSCH on the slot is not transmitted.

Case D-1: as shown in fig. 6, assuming that the base station schedules single PUSCH transmission in each of the slots n +3 to n +6 and each PUSCH starts to transmit from the first symbol in the slot, in this case, the terminal performs transmission control of the uplink control information by using the first preset collision condition, and then discards the PUSCH in the slot n +3 to the slot n +6 and transmits only the PUCCH.

In fig. 6, the hatched filling boxes indicate transmission of PUCCH, the vertical, cross grid, diagonal cross grid, and horizontal filling boxes indicate transmission of PUSCH, and the cross lines indicate that PUSCH on the slot is not transmitted.

Case I-2: as shown in fig. 15, assuming that the base station schedules single PUSCH transmission in each of slot n +3 to slot n +6, and PUSCH in slot n +3 and slot n +4 is transmitted from the first symbol in the slot, and PUSCH in slot n +5 and slot n +6 is transmitted from the fourth symbol in the slot, in this case, the transmission control of the uplink control information is performed by using the second preset collision condition, and the terminal multiplexes the uplink control information on the PUSCH in slot n +3 and slot n +4 for transmission, and does not transmit the PUCCH; in this case, regardless of how many symbols are occupied by PUCCH and PUSCH transmissions in one slot, as long as the PUCCH and PUSCH transmission start symbols are the same in one slot, uplink control information can be multiplexed on the PUSCH for transmission. The terminal discards the PUSCH in slot n +5 and slot n +6 and transmits only the PUCCH.

In fig. 15, the hatched filling boxes indicate transmission of PUCCH, the vertical, cross grid, diagonal and horizontal filling boxes indicate transmission of PUSCH, and the cross lines indicate that PUCCH or PUSCH on the slot is not transmitted.

Second, assuming that the base station configures the terminal with a repetition number of a multi-slot PUCCH of 4 through RRC signaling, and according to configuration information of semi-static uplink and downlink allocation of the base station, there are not enough uplink/unknown symbols available for the PUCCH in a slot n +4 to a slot n +6, the multi-slot PUCCH may be transmitted in a slot n +2, a slot n +3, a slot n +7, and a slot n +8, and all transmissions are performed from a first symbol in the slot, which is described below as an example for collision situations of different multi-slot PUCCHs and PUSCHs.

Case J: as shown in fig. 16, assuming that the base station schedules multi-slot PUSCH transmission in slot n +2 to slot n +9, and all start transmission from the first symbol in the slot, and the transmission of the PUSCH does not conflict with the uplink and downlink transmission directions semi-statically configured by the base station, the terminal multiplexes the uplink control information on the PUSCH in slot n +2, slot n +3, slot n +7, and slot n +8 for transmission, and does not transmit the PUCCH; in addition, since there are not enough uplink/unknown symbols available for the PUCCH in slot n +4 to slot n +6, if the time domain length of the PUSCH is longer than the PUCCH, there are also not enough uplink symbols available for transmission of the PUSCH, and thus the PUSCH in slot n +4 to slot n +6 cannot be transmitted either. In this case, regardless of how many symbols are occupied by PUCCH and PUSCH transmissions in one slot, as long as the PUCCH and PUSCH transmission start symbols are the same in one slot, uplink control information can be multiplexed on the PUSCH for transmission. It should be noted that, in this case, the same transmission effect can be achieved by using the first preset collision condition or the second preset collision condition to perform the transmission control of the uplink control information.

Case K-2: as shown in fig. 18, assuming that the base station schedules multi-slot PUSCH transmission in slot n +2 to slot n +5, and all start transmission from the first symbol in the slot, in this case, the second preset collision condition is adopted to perform transmission control on uplink control information, and the terminal multiplexes the uplink control information on the PUSCH in slot n +2 and slot n +3 for transmission, and does not transmit PUCCH; in this case, regardless of how many symbols are occupied by PUCCH and PUSCH transmissions in one slot, as long as the PUCCH and PUSCH transmission start symbols are the same in one slot, uplink control information can be multiplexed on the PUSCH for transmission.

In fig. 18, diagonal filled boxes indicate transmission of PUCCH, vertical filled boxes indicate transmission of PUSCH, and cross lines indicate that PUCCH in the slot is not transmitted.

Third, assuming that the base station configures the terminal with the repetition number of the multi-slot PUCCH as 4 through RRC signaling, occupies third to seventh symbols in each slot, and the base station does not perform semi-static uplink and downlink allocation or has enough uplink symbols for the PUCCH in the repeated slots of the PUCCH according to configuration information, then the multi-slot PUCCH performs repeated transmission in consecutive slots n +2 to n +5, which is illustrated below for different collision situations of the multi-slot PUCCH and the PUSCH respectively:

case M-1: as shown in fig. 19, assuming that the base station schedules multi-slot PUSCH transmissions in slot n +2 to slot n +5, and all start transmitting from the third symbol in the slot, occupying 10 symbols in one slot for transmission, in slot n +2 and slot n +3, it is assumed that slot configuration 34 is used, as shown in table 1 below:

U

table 1 specific slot configuration table for configuration 34

That is, in a time slot, the first is a downlink transmission symbol, the second is an unknown symbol, and the rest are uplink transmission symbols. In this case, the first preset collision condition is adopted to perform transmission control of the uplink control information, and the terminal may transmit the PUCCH or the PUSCH in the slot n +2 and the slot n + 3.

In slot n +4 and slot n +5, it is assumed that slot configuration 48 is used, as shown in table 2 below:

table 2 specific slot configuration table for configuration 48

That is, in a time slot, the first and seventh symbols are downlink transmission symbols, the second and eighth symbols are unknown symbols, and the rest are uplink transmission symbols. In the slot n +4 and the slot n +5, the terminal may transmit the PUCCH but cannot transmit the PUSCH, in which case, the uplink control information in the multi-slot PUCCH may still not be multiplexed in the PUSCH for transmission, in which case, the terminal performs transmission control of the uplink control information by using a first preset collision condition, and discards the PUSCH transmission in the slot n +2 to the slot n +5 and transmits only the PUCCH.

In fig. 19, a diagonal filled box indicates transmission of PUCCH, a vertical filled box indicates transmission of PUSCH, and a cross indicates that PUSCH on the slot is not transmitted.

Case M-2: as shown in fig. 20, the transmission conditions are the same as the case M-1, in this case, a second preset conflict condition is adopted to perform transmission control on the uplink control information, the terminal multiplexes the uplink control information on the PUSCH in the slot n +2 and the slot n +3 for transmission, and the PUCCH is not transmitted; in this case, regardless of how many symbols are occupied by PUCCH and PUSCH transmissions in one slot, as long as the PUCCH and PUSCH transmission start symbols are the same in one slot, uplink control information can be multiplexed on the PUSCH for transmission. The terminal discards the PUSCH transmission in slot n +4 and slot n +5 and transmits only the PUCCH.
