Description

UCI sending method, UCI receiving method, terminal and base station

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a sending method, a receiving method, a terminal, and a base station for UCI (Uplink control information).

Background

As the demand for mobile communication services has changed, various organizations such as ITU (International telecommunications union) have started to research NR (New radio communication system), for example, 5G NR (5Generation New RAT). In the NR system, UCI (Uplink control information) is supported for multiplexing transmission on PUSCH (Physical Uplink Shared Channel).

When the PUSCH uses frequency hopping transmission, if there is UL-SCH (Uplink Shared Channel) data transmission in the PUSCH, the number of coding bits of the UCI is uniformly divided into two parts, and the two parts are transmitted in frequency hopping resources of two hops, respectively. If no UL-SCH transmission exists in the PUSCH, the coding bit number of UCI is uniformly divided into two parts, meanwhile, the number of UCI coding bits which can be mapped in the frequency hopping resource of the first hop is obtained by taking the frequency hopping resource of the first hop as an upper limit, and then the rest UCI modulation symbols are mapped in the frequency hopping resource of the second hop.

However, when PUSCH uses frequency hopping transmission, the UCI transmitted in the frequency hopping resource of each hop is calculated by using the existing method, and it may happen that RE resources of PUSCH in the frequency hopping resource of one hop for UCI transmission are not enough to carry the number of coded bits allocated in the frequency hopping resource of the hop by the UCI, thereby causing UCI to be discarded, and degrading system transmission performance.

In the NR communication system, HARQ-ACK (Hybrid Automatic Repeat reQuest) and CSI (Channel State Information) may be transmitted through PUSCH. When the number of the HARQ-ACK bits is not more than 2, carrying out punching transmission on the PUSCH by the HARQ-ACK; and when the number of the HARQ-ACK bits is larger than 2, carrying out rate matching transmission on the HARQ-ACK and the PUSCH. And carrying out rate matching transmission on the CSI and the PUSCH, and mapping the HARQ-ACK and the CSI on all layers of a transmission block on the PUSCH for transmission.

HARQ-ACK maps from the first non-DMRS symbol after the first DMRS (Demodulation Reference Signal) on PUSCH. And when the number of the HARQ-ACK bits is not more than 2, reserving a part of resources. When the HARQ-ACK bit is 0 or 1 or 2, HARQ-ACK resource reservation is always performed according to 2 bits, and if the actual HARQ-ACK bit is 1 bit, mapping is performed on a part of resources in the reserved resources.

The CSI is mapped from the first non-DMRS symbol on the PUSCH, when the information bit of the HARQ-ACK is less than 2, reserved resources of the HARQ-ACK exist on the PUSCH, CSI part 1 (first part CSI) is not mapped on the reserved resources, and CSI part2 (second part CSI) can be mapped on the reserved resources; and if the information bit of the HARQ-ACK is more than 2, carrying out rate matching transmission on the PUSCH, and then mapping neither the CSI part 1 nor the CSI part2 on the HARQ-ACK resource.

And the UCI performs frequency domain discrete mapping in the transmission bandwidth of the PUSCH according to the sequence of the frequency domain first and the time sequence second. For a certain UCI type, the interval d between coded bits on one OFDM (Orthogonal Frequency Division Multiplexing) symbol is determined as follows: if the number of the residual unmapped coding bits of the UCI is greater than or equal to the number of available REs on the current OFDM symbol, d is 1; otherwise, d is floor (the number of available REs (Resource elements) on the current OFDM symbol/the number of remaining unmapped coding bits of UCI), where floor is a rounding-down operation.

When the PUSCH uses frequency hopping transmission, if UL-SCH data transmission exists in the PUSCH, the coding bit number of UCI is uniformly divided into two parts and the two parts are respectively transmitted in frequency hopping resources of two hops. If no UL-SCH transmission exists in the PUSCH, the coding bit number of UCI is uniformly divided into two parts, meanwhile, the number of UCI coding bits which can be mapped in the frequency hopping resource of the first hop is obtained by taking the frequency hopping resource of the first hop as an upper limit, and then the rest UCI modulation symbols are mapped in the frequency hopping resource of the second hop.

If there is UL-SCH data transmission in the PUSCH, the number of coding bits of UCI is evenly divided into two parts, and it may occur that the hopping resource of one hop is insufficient to carry the number of UCI bits of the hopping resource allocated at the hop. For example, as shown in fig. 1, PUSCH transmission contains 8 OFDM symbols, and when PUSCH is transmitted using frequency hopping, there are 4 OFDM symbols in each hop, and DMRS in the first hop occupies the fourth OFDM symbol, and DMRS in the second hop occupies the first OFDM symbol. According to the UCI mapping rule defined in NR, HARQ-ACK cannot be mapped in the first hop because there is no available resource after DMRS in the first hop, but according to the current allocation, half of the number of HARQ-ACK coded bits needs to be mapped in the first hop, which results in that half of the HARQ-ACK modulation symbols are discarded because they cannot be mapped.

If no UL-SCH data transmission exists in the PUSCH, the coding bit number of UCI is uniformly divided into two parts, meanwhile, the number of UCI coding bits which can be mapped in a first hop is obtained by taking the hopping resource of the first hop as an upper limit, and then the rest UCI coding bits are mapped in the hopping resource of a second hop. Thus, there may be a case where the frequency hopping resource of the first hop is sufficient and the frequency hopping resource of the second hop is insufficient to carry half of the number of UCI coding bits allocated according to the above-described manner. For example, as shown in fig. 2, HARQ-ACK occupies 26 RE resources, all mapped within the second hop. If the CSI part 1 contains 32 coding bits, 16 coding bits need to be mapped in each hop according to the current allocation method, but only 10 REs are available for mapping the CSI part 1 in the second hop, which may cause part of the CSI part 1 coding bits to be discarded because they cannot be mapped.

When the PUSCH uses frequency hopping transmission, the UCI determines the number of coded bits mapped within two hops according to the following formula:

if HARQ-ACK is transmitted on PUSCH where UL-SCH is present:

the number of coded bits mapped by the HARQ-ACK in the frequency hopping resource of the first hop is as follows:

the number of coded bits mapped by the HARQ-ACK in the frequency hopping resource of the second hop is:

if CSI is transmitted on the PUSCH where the UL-SCH is present:

the number of coded bits mapped by the CSI part 1 in the frequency hopping resource of the first hop is as follows:

the number of coded bits mapped by the CSI part 1 in the second hop frequency hopping resource is:

the number of coded bits mapped by the CSI part2 in the frequency hopping resource of the first hop is:

the number of coded bits mapped by the CSI part2 in the second hop frequency hopping resource is:

if HARQ-ACK and CSI part 1 are transmitted on PUSCH without UL-SCH, then

G^ACK(2)＝G^ACK-G^ACK(1)；

G^CSI-part1(1)＝M₁·N_L·Q_m-G^ACK(1)；

G^CSI-part1(2)＝G^CSI-part1-G^CSI-part1(1)。

If HARQ-ACK, CSI part 1 and CSI part2 are transmitted on the PUSCH without the UL-SCH, then:

G^ACK(2)＝G^ACK-G^ACK(1)；

G^CSI-part1(2)＝G^CSI-part1-G^CSI-part1(1)；

when the HARQ-ACK bit number is not more than 2:

G^CSI-part2(1)＝M₁·N_L·Q_m-G^CSI-part1(1)；

G^CSI-part2(2)＝M₂·N_L·Q_m-G^CSI-part1(2)；

when the HARQ-ACK bit number is not more than 2:

G^CSI-part2(1)＝M₁·N_L·Q_m-G^ACK(1)-G^CSI-part1(1)；

G^CSI-part2(2)＝M₂·N_L·Q_m-G^ACK(2)-G^CSI-part1(2)。

wherein G is^ACKThe total coding bit number is HARQ-ACK;

G^CSI-part1the total coding bit number is HARQ-ACK;

G^CSI-part2the total coding bit number is HARQ-ACK;

N_Lthe number of transmission layers of the PUSCH;

The terminal may determine one hop, which may be limited in resources for transmitting a specific type of UCI, provided in the frequency hopping resources of the PUSCH, as the target hop. Specifically, the terminal may determine that, among the frequency hopping resources of the PUSCH, one hop that provides the least resources for transmitting a specific type of UCI is the target hop. When the specific type of UCI is HARQ-ACK, it is considered that only the first hop of the frequency hopping resources of the PUSCH is a hop that may be resource restricted, that is, the terminal may determine that the first hop of the frequency hopping resources of the PUSCH is the target hop.

And determining the residual coding bit number of the specific type of UCI, which is the coding bit number transmitted by the specific type of UCI in the frequency hopping resource of the second hop of the PUSCH.

And when the second hop of the PUSCH is the target hop, the terminal determines the number of coding bits provided in the frequency hopping resource of the second hop and used for transmitting the resource bearer of the UCI of the specific type, and is an upper limit of the number of coding bits transmitted by the UCI of the specific type in the frequency hopping resource of the target hop. And determining the residual coding bit number of the specific type of UCI, which is the coding bit number transmitted by the specific type of UCI in the frequency hopping resource of the first hop of the PUSCH.

The terminal may determine, using the number of coded bits of the resource bearer for transmitting the UCI of the specific type provided in the frequency hopping resource of the target hop as an upper limit, the number of coded bits transmitted by the UCI of the specific type in the frequency hopping resource of the target hop. Specifically, the terminal may determine that the number of coded bits of the UCI of the specific type transmitted in the frequency hopping resource of the target hop is less than or equal to the number of coded bits of a resource bearer provided in the frequency hopping resource of the target hop and used for transmitting the UCI of the specific type.

The invention is described below by way of example with reference to specific examples:

example one:

assuming that the PUSCH is frequency hopping transmission, the number of transmission layers is 1, the modulation order is 2, 10 OFDM symbols are occupied, each hop includes 5 OFDM symbols, the DMRS occupies the fourth OFDM symbol in the first hop, and the DMRS occupies the first OFDM symbol in the second hop. If HARQ-ACK and CSI are transmitted on the PUSCH with UL-SCH, the HARQ-ACK contains 96 coding bits and occupies 48 RE resources, and the CSI occupies 26 RE resources containing 52 coding bits. The mapping resources of HARQ-ACK and CSI within each hop are determined in the following manner, and the mapping result is shown in fig. 5:

for HARQ-ACK, the number of available RE resources in the first hop is 12, the number of available RE resources in the second hop is 36, the number of available RE resources in the first hop is smaller than the number of available RE resources in the second hop, and it is determined that the first hop is HARQ-ACK as the target hop. Taking the number of RE resources available for HARQ-ACK in the first hop as the upper limit of the number of modulation coding bits allocated for HARQ-ACK in the first hop, the number of coding bits that can be mapped by HARQ-ACK in the first hop is

Occupying 12 RE resources; the number of encoding bits that HARQ-ACK can map in the second hop is G^ACK(2)＝G^ACK-G^ACK(1) 96-24-72, 36 RE resources are occupied.

For CSI, the number of available RE resources in the first hop is 48-12 (the number of RE resources occupied by HARQ-ACK in the first hop) is 36, and the number of available RE resources in the second hop is 48-36 (the number of RE resources occupied by HARQ-ACK in the second hop) is 12. Determining the second hop as the target hop, and taking the number of the RE resources which can be used for the CSI in the second hop as the upper limit of the number of the encoding bits distributed by the CSI in the second hop, so that the number of the encoding bits which can be mapped by the CSI in the second hop is equal to

Occupying 12 RE resources; the number of encoding bits that CSI can be mapped in the first hop is G^CSI-part1(1)＝G^CSI-part1-G^CSI-part1(2) 52-24-28, occupying 14 RE resourcesA source.

If a-CSI (Aperiodic Channel State Information) is transmitted on a PUSCH without UL-SCH, CSI part 1 contains 152 coded bits and occupies 76 RE resources, and CSI part2 contains 16 coded bits and occupies 8 RE resources. The mapping resources of the CSI part 1 and the CSI part2 within each hop may be determined in the following manner, and the mapping result is shown in fig. 5:

for CSI part 1, the number of available RE resources in the first hop is 48-0 (the number of RE resources occupied by HARQ-ACK in the first hop) is 48, and the number of available RE resources in the second hop is 36-0 (the number of RE resources occupied by HARQ-ACK in the second hop) is 36. And if the number of the available RE resources in the second hop is smaller than that in the first hop, the second hop is the hop with the limited CSI part 1 resources, and the second hop is determined to be the target hop. Taking the number of RE resources available for the CSI part 1 in the second hop as the upper limit of the number of coding bits allocated by the CSI part 1 in the second hop, the number of coding bits that the CSI part 1 can map in the second hop is:

occupy 36 RE resources; the number of encoding bits that CSI part 1 can map in the first hop is G^CSI-part1(1)＝G^CSI-part1-G^CSI-part1(2) 152-72-80, occupying 40 RE resources;

for CSI part2, the number of available RE resources in the first hop is 48-0 (the number of RE resources occupied by HARQ-ACK in the first hop) -40 (the number of RE resources occupied by CSI part 1 in the first hop) is 8, the number of available RE resources in the second hop is 36-0 (the number of RE resources occupied by HARQ-ACK in the second hop) -36 (the number of RE resources occupied by CSIpart 1 in the second hop) is 0, the number of available RE resources in the second hop is less than the number of available RE resources in the first hop, the second hop is a hop with CSI part2 resources limited, and the second hop is determined to be the target hop. Taking the number of RE resources available for the CSI part2 in the second hop as the upper limit of the number of coding bits allocated by the CSI part 1 in the second hop, the number of coding bits that the CSI part2 can map in the second hop is:

occupying 0 RE resource; the number of encoding bits that CSI part2 can map in the first hop is G^CSI-part1(1)＝G^CSI-part1-G^CSI-part1(2) 16-0-16, 8 RE resources are occupied.
