In order for Ligui examiners to understand the technical characteristics, content and advantages of the present invention and the effects it can achieve, the present invention is hereby combined with the accompanying drawings and appendices, and is described in detail in the form of embodiments as follows, and the drawings used therein , the purpose of which is only for illustration and auxiliary instructions, and not necessarily the true proportion and precise configuration of the present invention after implementation, so it should not be interpreted based on the proportion and configuration relationship of the attached drawings, and limit the application of the present invention in actual implementation The scope is described first.

In describing the present invention, it is to be understood that the terms "center", "lateral", "upper", "lower", "left", "right", "top", "bottom", "inner", " The orientations or positional relationships indicated in the drawings are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, Specific orientation configurations and operations, therefore, are not to be construed as limitations on the invention.

In the NR system, when the high-level signaling configures the UE to allow a Physical Downlink Shared Channel (PDSCH) reception to have up to two transport blocks (Transport block, TB), the high-level signaling can also configure the allowed space for the UE The parameter of spatial bundling is used to instruct the UE to feed back only 1-bit HARQ-ACK to two TBs, thereby effectively reducing the number of HARQ-ACK feedback bits. However, currently, the parameter of whether to allow the spatial bundling of the HARQ-ACK is configured for an uplink channel, such as a physical uplink control channel (Physical Uplink Control Channel, PUCCH) or a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH). During the Rel-17 ultra-reliable low latency communication (Ultra-Reliable Low Latency Communication, URLLC) research process, the conclusion of the meeting allows multiple uplink control information (Uplink Control Information, UCI) with different priorities to be multiplexed on the same uplink channel transmission. At this time, the HARQ-ACKs with high priority and low priority will both perform spatial bundling or will not perform spatial bundling. However, HARQ-ACKs with different priorities have different requirements for reducing the number of bits and ensuring transmission performance. The existing technology cannot reduce the performance impact caused by spatial bundling feedback on the premise of reducing the total number of bits of HARQ-ACK with different priorities. .

Hybrid Automatic Repeat reQuest-ACKnowledge (HARQ-ACK) is the feedback information transmitted by the UE to the base station as to whether the PDSCH is received correctly. The HARQ-ACK codebook is a HARQ-ACK feedback information sequence transmitted on a PUCCH or PUSCH. In order to reduce the size of the HARQ-ACK codebook, NR supports HARQ-ACK spatial combination. Whether to use HARQ-ACK spatial combination on PUCCH and PUSCH is configured independently. For an uplink transmission channel, when the high-level signaling configures a PDSCH for the UE to have a maximum of two TBs, if the high-level signaling does not configure the use of HARQ-ACK spatial combination, the UE responds to the two TBs separately. Feed 1-bit HARQ-ACK; if high-level signaling configures HARQ-ACK spatial combination, use the "AND" operation to combine the HARQ-ACK bits of two TBs and only feed back 1-bit HARQ-ACK.

In the research process of Rel-16 URLLC, considering the different transmission priorities of different types of services, two levels of priorities are defined, namely High Priority (HP) and Low Priority (LP). Therefore, HARQ-ACK is also divided into high-priority HARQ-ACK and low-priority HARQ-ACK, and the priority of HARQ-ACK is indicated by the DCI of dynamically scheduling PDSCH or the DCI of starting semi-static PDSCH. In Rel-16, only multiple UCIs with the same priority are supported to be transmitted on the same uplink channel. UCI includes HARQ-ACK, scheduling request (Scheduling Request, SR) and channel status information (Channel Situation Information, CSI), etc. Currently, Rel-17 has allowed UCIs with different priorities to be multiplexed during transmission on the same uplink channel. Therefore, an uplink channel may transmit HARQ-ACK with high priority and HARQ-ACK with low priority at the same time. If HARQ-ACK spatial combination is used in high-layer signaling configuration, both high-priority HARQ-ACK and low-priority HARQ-ACK need to perform spatial combination to compress feedback bits.

In the prior art, the UE is configured to combine HARQ-ACK slots according to the uplink channel type. When HARQ-ACKs with different priorities are multiplexed and transmitted on the same uplink channel, the high-priority HARQ-ACK and the low-priority HARQ-ACK obey the same rules. According to the configuration of the uplink channel on the network side, it is determined whether to perform spatial consolidation (both high-priority and low-priority HARQ-ACKs will perform spatial bundling or neither will perform spatial bundling), and there is no guarantee that the difference will be reduced. The transmission performance of HARQ-ACK with different priority orders is satisfied under the premise of the total number of bits of the priority order HARQ-ACK.

Based on the above-mentioned technical problems, an embodiment of the present invention proposes an information transmission method. When HARQ-ACKs with different priorities are multiplexed in the same uplink channel for transmission, HARQ-ACKs with different priorities are independently configured whether to perform space Combined to ensure that the transmission performance of HARQ-ACK with different priorities is satisfied under the premise of reducing the total number of bits of HARQ-ACKs with different priorities.

If the total number of bits exceeds the first threshold, the terminal does not perform spatial combination on high-priority HARQ-ACKs, but performs spatial combination on low-priority HARQ-ACKs to generate a HARQ-ACK codebook.

The information transmission methods in the above-mentioned embodiments are further described below with several specific examples:

example 1:

The new high-level signaling configures whether to perform spatial combination on the high-priority HARQ-ACK and the low-priority HARQ-ACK respectively. In this example, the high-level signaling is that the high-priority HARQ-ACK is not configured with spatial combination, and that the low-priority HARQ-ACK is configured with spatial combination. As shown in Figure 2, it is assumed that the terminal needs to feed back HARQ-ACK to three PDSCHs in the current time slot slot n, among which the HARQ-ACK configured in the scheduling DCI corresponding to the PDSCH in slot n-3 and slot n-2 is a high priority sequence, the HARQ-ACK configured in the scheduling DCI corresponding to the PDSCH in slot n-1 has a low priority.

At this time, when HARQ-ACKs of different priorities are multiplexed and transmitted, HARQ-ACKs of high priority do not need to be combined, and PDSCH#1 and PDSCH#2 correspond to 4-bit high-priority HARQ-ACK. The low priority HARQ-ACK needs to be combined, and PDSCH#3 corresponds to 1 bit low priority HARQ-ACK.

In this example, the HARQ-ACKs with different priorities adopt a joint coding method, and similarly, two HARQ-ACK codebooks can be generated using an independent coding method.

Wherein, the uplink channel for transmitting the HARQ-ACK codebook in slot n may be PUCCH or PUSCH, which is not limited in this example. When the high-layer signaling is whether to perform spatial combination according to HARQ-ACK configurations with different priorities, the terminal ignores the parameter of whether to perform spatial combination according to channel configuration in the prior art.

If high-level signaling is configured with high-priority HARQ-ACK and low-priority HARQ-ACK at the same time or without spatial combination, HARQ-ACK with different priorities generates a multiplexed HARQ-ACK codebook according to the spatial combination configuration. The process is similar to the above embodiment, and will not be described in detail.

Example 2:

The new high-level signaling configures whether to perform spatial combination on the high-priority HARQ-ACK and the low-priority HARQ-ACK respectively. In this example, high-level signaling configures space combining for high-priority HARQ-ACK, and configures space combining for low-priority HARQ-ACK. Assuming that the terminal needs to feed back HARQ-ACK to three PDSCHs in the current time slot, the HARQ-ACK configured in the scheduling DCI corresponding to the PDSCH in slot n-3 and slot n-2 has a high priority, and the PDSCH in slot n-1 The HARQ-ACK configured in the corresponding scheduling DCI has a low priority.

At this time, when HARQ-ACKs of different priorities are multiplexed and transmitted, HARQ-ACKs of high priority need to be combined, and PDSCH#1 and PDSCH#2 correspond to 2-bit high-priority HARQ-ACK. The low-priority HARQ-ACK is subject to the high-priority HARQ-ACK spatial combination configuration and combined, and PDSCH#3 corresponds to 1-bit low-priority HARQ-ACK.

In this example, the HARQ-ACKs with different priorities adopt a joint coding method, and similarly, two HARQ-ACK codebooks can be generated using an independent coding method.

Wherein, the uplink channel for transmitting the HARQ-ACK codebook in slot n may be PUCCH or PUSCH, which is not limited in this example. When the high-layer signaling is whether to perform spatial combination according to HARQ-ACK configurations with different priorities, the terminal ignores the parameter of whether to perform spatial combination according to channel configuration in the prior art.

Example 3:

Added high-level signaling to configure whether to perform spatial combination on low-priority HARQ-ACK. This high-level signaling is different from the parameters configured for each uplink channel in the prior art, and can be compared with the parameters configured for each uplink channel. combination of set parameters. That is, the spatial combination parameter configured for each uplink channel is used to determine whether to perform spatial combination on the high-priority HARQ-ACK.

In this example, high-level signaling configures the PUCCH not to perform spatial combination based on the existing technology, and at this time, the high-priority HARQ-ACK does not perform spatial combination. The low-priority HARQ-ACK determines whether to perform spatial combination based on new high-layer signaling.

If the new high-level signaling configures low-priority HARQ-ACK for spatial combination, when the two priority HARQ-ACKs are multiplexed on the same uplink channel, the high-priority HARQ-ACK will not be spatially combined, and the low-priority HARQ- ACK for space coalescing. The HARQ-ACK codebook is shown in FIG. 2 .

If the new high-level signaling configures low-priority HARQ-ACK without spatial combination, when the two priority HARQ-ACKs are multiplexed on the same uplink channel, the high-priority HARQ-ACK will not be spatially combined, and the low-priority HARQ -ACK does not perform spatial combination, and the HARQ-ACK codebook is shown in Figure 4 .

In this example, the HARQ-ACKs with different priorities adopt a joint coding method, and similarly, two HARQ-ACK codebooks can be generated using an independent coding method.

Similarly, in this example, configuring whether to perform spatial combination on the PUCCH based on the existing technology may be replaced with configuring whether to perform spatial combination on the PUSCH based on the existing technology.

Example 4:

Added high-level signaling to configure whether to perform spatial combination on low-priority HARQ-ACK. The high-level signaling is different from the parameters configured for each uplink channel in the prior art, and can be used in combination with the parameters configured for each uplink channel. That is, the spatial combination parameter configured for each uplink channel is used to determine whether to perform spatial combination on the high-priority HARQ-ACK.

In this example, high-level signaling configures the PUCCH to perform spatial combination based on the existing technology, and the high-priority HARQ-ACK performs spatial combination.

At this time, if the low priority HARQ-ACK and high priority HARQ-ACK are multiplexed and transmitted on the same channel, the low priority HARQ-ACK is subject to the high priority HARQ-ACK spatial combination configuration and combined, that is, the newly added The high-level signaling configures the parameters of whether the low-priority HARQ-ACK performs spatial combination, and the HARQ-ACK codebook is shown in Figure 3.

Similarly, in this example, configuring whether to perform spatial combination on the PUCCH based on the existing technology may be replaced with configuring whether to perform spatial combination on the PUSCH based on the existing technology.

Example 5:

When HARQ-ACKs with different priorities are transmitted on the same uplink channel using joint coding, the terminal determines whether the HARQ-ACK needs to be spatially combined based on the parameters configured for each uplink channel based on high-level signaling. If spatial combination is required, According to the prior art, spatial combination is performed on the high-priority HARQ-ACK and the low-priority HARQ-ACK respectively.

If high-level signaling configuration does not require spatial combining, then high-priority HARQ-ACK does not need spatial combining, while low-priority HARQ-ACK needs to further judge whether the total number of bits of HARQ-ACK exceeds the destination code of the current uplink channel. The carrying capacity under the rate is used to determine whether space consolidation is required.

If spatial combination is required, According to the prior art, spatial combination is performed on the high-priority HARQ-ACK and the low-priority HARQ-ACK respectively.

If the high-level signaling configuration does not require space combining, both the high-priority HARQ-ACK and the low-priority HARQ-ACK need to further judge whether the corresponding HARQ-ACK bits exceed the priority HARQ-ACK of the current uplink channel. Whether space combining is required is determined based on the bearing capacity of allocated resources at the target code rate.

The transmission performance of HARQ-ACK with different priorities is satisfied on the premise.
