For Multi-TRP transmission scheduled based on a plurality of DCIs, supporting joint HARQ-ACK feedback (Jointfeedback) and separating HARQ-ACK feedback (Seperatefeedback), specifically configuring by a high-layer signaling ACKNACKFeedbacmode, and if the configured ACKNACKFeedbacmode is Jointfeedback, supporting joint feedback; separation feedback is supported if ACKNACKFeedbacmode is configured as SeparateFeedback.

Currently, NR R16 supports Multi-TRP Transmission, that is, supports Transmission communication between a terminal and multiple Transmission points (TRPs), and supports each control resource set CORESET to associate with one higher layer signaling index, each PUCCH resource to associate with one higher layer signaling index, and the higher layer signaling index is an identifier of the TRP at some level. However, if the higher layer signaling identifier of the control resource set CORESET where the PDCCH for scheduling the PUCCH is located is different from the higher layer signaling identifier of the PUCCH, or the TRP indicated by the higher layer signaling identifier of the control resource set CORESET where the PDCCH for scheduling the PUCCH is located is different from the TRP indicated by the higher layer signaling identifier of the PUCCH, no specific terminal behavior is specified at present.

To solve the above problem, please refer to fig. 2A, where fig. 2A is a transmission method of uplink control information provided in an embodiment of the present application, and is applied in a 5G SA or NSA networking system, the method includes:

step 2A01, the terminal detects that the high-level signaling identification of the control resource set CORESET where the physical downlink control channel PDCCH for scheduling the physical uplink control channel PUCCH is located is different from the high-level signaling identification of the PUCCH.

The PDCCH, i.e., a downlink control channel, is mainly used to carry uplink scheduling information and downlink scheduling information. The control information carried on the PDCCH is called Downlink Control Information (DCI), and the DCI is classified into different types by the protocol due to its many functions.

Step 2A02, the terminal determines to respond to the current PUCCH sending event by adopting a preset mode, wherein the preset mode is a response strategy agreed by a protocol.

It can be seen that, in the embodiment of the present application, when a terminal detects that a high-level signaling identifier of a control resource set CORESET where a physical downlink control channel PDCCH for scheduling a physical uplink control channel PUCCH is located is different from a high-level signaling identifier of the PUCCH, the terminal determines to respond to the current PUCCH transmission event by using a preset mode, where the preset mode is a response policy agreed by a protocol. Therefore, the terminal can solve the problem of how the terminal configures the PUCCH for transmission under the condition of high-level signaling mark conflict, and the reliability and robustness of transmission are improved.

In one possible example, the preset mode comprises any one or more of the following combinations: ignoring the spatial information configured by the PUCCH at the high layer, and sending the PUCCH by adopting the spatial information related to the spatial information of the CORESET where the PDCCH is located; transmitting the PUCCH according to the spatial domain information configured by the PUCCH high layer; forgoing transmission of the PUCCH; and determining that the current event is an error event, and giving up sending the PUCCH.

And the terminal ignores the spatial information configured by the PUCCH high layer and adopts the spatial information related to the spatial information of the CORESET where the PDCCH is located. The spatial information related to the spatial information of the core set where the PDCCH is located refers to uplink spatial information related to the spatial information, and is usually implemented depending on a terminal. For example, the configuration of the main parameters of the CORESET is shown in table 1.

TABLE 1

The beam direction refers to a signal transceiving direction in a beam forming (Beamforming) technology, and the beam forming is also called beam forming and spatial filtering, and is a signal processing technology for directionally transmitting and receiving signals by using a sensor array. Beamforming techniques allow signals at certain angles to achieve constructive interference and signals at other angles to achieve destructive interference by adjusting parameters of the basic elements of the phased array. Beamforming can be used for both signal transmitting and receiving ends.

After the terminal gives up sending the PUCCH, the terminal receives resource configuration information or resource configuration indication of network equipment again after a period of time, and the uplink spatial domain information related to the spatial domain information of the CORESET where the PDCCH is located is triggered or the PUCCH is sent according to the spatial domain information configured by the PUCCH at the high level until the high level signaling identification is detected to be consistent.

In this example, when detecting that the high-level signaling identifier of the control resource set CORESET where the physical downlink control channel PDCCH for scheduling the physical uplink control channel PUCCH is located is different from the high-level signaling identifier of the PUCCH, the terminal sends the PUCCH by using the uplink spatial domain information associated with the spatial domain information of the CORESET where the PDCCH is located, that is, ignoring the spatial domain information configured by the high level of the PUCCH; or, transmitting the PUCCH according to the spatial domain information configured by the PUCCH high layer; or, abandoning transmitting PUCCH; or determining that the current event is an error event, and abandoning to transmit the PUCCH. Therefore, the terminal can solve the problem of how the terminal configures the PUCCH for transmission under the condition of high-level signaling mark conflict, avoid the disordered configuration of the PUCCH caused by signaling mark conflict, and is beneficial to improving the reliability and robustness of transmission.

In one possible example, the preset mode includes ignoring spatial information configured by a high layer of the PUCCH, and transmitting the PUCCH by using spatial information associated with spatial information of a CORESET where the PDCCH is located; before the terminal determines to respond to the current PUCCH sending event in a preset manner, the method further includes: the terminal is configured by a higher layer as joint feedback; alternatively, the terminal is configured by a higher layer to separate the feedback.

When the terminal is configured to be the joint feedback or the separation feedback by the high layer, the terminal ignores the spatial information configured by the high layer of the PUCCH and transmits the PUCCH by adopting the spatial information associated with the spatial information of the CORESET where the PDCCH is located.

It can be seen that, in this example, the terminal is configured as joint feedback by the higher layer, or the terminal is configured as separate feedback by the higher layer, and the error code caused by link adaptation can be efficiently compensated by using the hybrid automatic retransmission technology, so that the data transmission rate is increased, the data transmission delay is reduced, and the accuracy of resource configuration is improved.

In one possible example, the preset mode includes transmitting the PUCCH according to spatial information configured by the PUCCH higher layer; before the terminal determines to respond to the current PUCCH sending event in a preset manner, the method further includes: the terminal is configured by a higher layer as joint feedback; alternatively, the terminal is configured by a higher layer to separate the feedback.

When the terminal is configured as the joint feedback or the separation feedback by the high layer, the terminal transmits the PUCCH by adopting the spatial information configured according to the PUCCH high layer.

It can be seen that in this example, the terminal is configured by the higher layer as joint feedback; or the terminal is configured to separate feedback by a high layer, and the error code caused by adopting link adaptation can be efficiently compensated by adopting a hybrid automatic retransmission technology, so that the data transmission rate is improved, the data transmission delay is reduced, and the accuracy of resource configuration is improved.

In one possible example, the preset manner includes dropping transmission of the PUCCH; before the terminal determines to respond to the current PUCCH sending event in a preset manner, the method further includes: the terminal is configured by a high layer to identify conflict non-response by high layer signaling; alternatively, the terminal is configured by a higher layer to separate the feedback.

And when the terminal is configured by a higher layer to identify conflict non-response or separate feedback, the terminal abandons to send the PUCCH.

As can be seen, in this example, when the terminal is configured by the higher layer to not respond to the collision of the higher layer signaling identifier, or when the terminal is configured by the higher layer to separately feed back, the PUCCH transmission event for transmitting the PUCCH response this time is abandoned, so that the resource configuration abnormality can be avoided, and the accuracy of the resource configuration can be improved.

In a possible example, the preset mode includes determining that the current event is an error event, and abandoning to send the PUCCH; before the terminal determines to respond to the current PUCCH sending event in a preset manner, the method further includes: the terminal is configured by a high layer to identify conflict non-response by high layer signaling; alternatively, the terminal is configured by a higher layer to separate the feedback.

The triggering condition for determining that the current event is an error event is that the terminal is configured by a high-level signaling to identify conflict and not respond or to be separated feedback. After the terminal gives up sending the PUCCH, the terminal receives the resource configuration information or the resource configuration indication of the network equipment again after a period of time, and the terminal triggers the spatial domain information related to the spatial domain information of the CORESET where the PDCCH is located or sends the PUCCH according to the spatial domain information configured by the PUCCH at the high level until the high level signaling identification is detected to be consistent.

In this example, when the terminal is configured by the high layer to not respond to the high layer signaling identifier conflict or configured by the high layer to separately feed back, it is determined that the current event is an error event, and the PUCCH is abandoned to be sent, so that resource configuration abnormality can be avoided, and accuracy of resource configuration is improved.

In one possible example, the terminal receives resource configuration information from a network device, where the resource configuration information includes a high layer signaling identifier of a core set where the PDCCH for scheduling the PUCCH is located.

In a specific implementation, the resource configuration information may be a core set and a Search Space parameter set issued by a network device.

Therefore, in this example, the terminal receives the resource configuration information from the network device, and detects the high-level signaling identifier conflict in time according to the information, and the terminal does not need to perform further information analysis processing after receiving the information, thereby improving the decision-making real-time performance of the local terminal device.

In one possible example, the terminal receives resource configuration information from a network device, where the resource configuration information includes the higher layer signaling identifier for the PUCCH resource.

In one possible example, the high-layer signaling identifier is a high-layer signaling index, and the high-layer signaling index is used for identifying a single TRP in a plurality of transmitting and receiving nodes TRP; and the terminal performs data transmission with the plurality of TRPs through a Multi-TRP transmission mechanism.

In a specific implementation, the Multi-TRP transmission mechanism may be used in an URLLC scenario of ultra-high reliable low-latency communication, and may also be used in an eMBB scenario of mass machine communication, which is not limited herein.

In this example, the terminal accesses the 5G NR system, and the Multi-TRP transmission mechanism is used to improve the stability and robustness of data transmission.

The following is a detailed description with reference to specific examples.

Example 1, assuming that a mobile communication network accessed by a terminal is a 5G NR SA network, and a rule pre-configured by the terminal and a base station is to transmit a PUCCH using spatial information associated with spatial information of a CORESET where a PDCCH is located when a high layer signaling identifier collision occurs, as shown in fig. 2B, the terminal performs the following operations:

step 2B01, the terminal detects that the high-level signaling identification of the control resource set CORESET where the physical downlink control channel PDCCH for scheduling the physical uplink control channel PUCCH is located is different from the high-level signaling identification of the PUCCH;

step 2B02, the terminal is configured to joint feedback by a high layer;

and step 2B03, the terminal ignores the spatial information configured by the PUCCH high layer, and transmits the PUCCH by adopting the spatial information associated with the spatial information of the CORESET where the PDCCH is located.

In this example, the terminal defaults to transmit the PUCCH with the spatial information associated with the spatial information of the CORESET where the PDCCH is located, in response to a situation of a high-level signaling identifier collision, so that the PUCCH is prevented from being configured in a disordered manner due to the signaling identifier collision, and the reliability and robustness of transmission are improved.

Example 2, assuming that a mobile communication network accessed by a terminal is a 5G NR NSA networking, and a rule pre-configured by the terminal and a base station is that when a higher layer signaling identifier conflicts, the PUCCH is sent according to spatial information configured by the PUCCH higher layer, as shown in fig. 2C, the terminal performs the following operations:

step 2C01, the terminal detects that the high-level signaling identification of the control resource set CORESET where the physical downlink control channel PDCCH for scheduling the physical uplink control channel PUCCH is located is different from the high-level signaling identification of the PUCCH;

and step 2C02, the terminal sends the PUCCH according to the spatial domain information configured by the PUCCH high layer.

In this example, the terminal defaults to transmit the PUCCH according to the airspace information configured by the PUCCH at a high level for the case of collision of high-level signaling identifiers, so that PUCCH configuration confusion caused by collision of signaling identifiers is avoided, and transmission reliability and robustness are improved.

Example 3, assuming that the mobile communication network accessed by the terminal is a 5G NR NSA networking, and the rule pre-configured by the terminal and the base station is to abandon sending the PUCCH, as shown in fig. 2D, the terminal performs the following operations:

step 2D01, the terminal detects that the high-level signaling identification of a control resource set CORESET where a physical downlink control channel PDCCH for scheduling a physical uplink control channel PUCCH is located is different from the high-level signaling identification of the PUCCH;

step 2D02, the terminal is configured by the higher layer to identify conflict non-response by the higher layer signaling

And step 2D03, the terminal abandons sending the PUCCH.

As can be seen, in this example, the terminal gives up sending the PUCCH by default for the case of high-level signaling identifier collision, thereby avoiding PUCCH configuration confusion caused by signaling identifier collision, and facilitating improvement of transmission reliability and robustness.

In example 4, assuming that the mobile communication network accessed by the terminal is a 5G NR SA networking, and a rule pre-configured by the terminal and the base station is to determine that the current event is an error event, and abandon sending the PUCCH, as shown in fig. 2E, the terminal performs the following operations:

step 2E01, the terminal detects that the high-level signaling identifier of the control resource set CORESET where the physical downlink control channel PDCCH for scheduling the physical uplink control channel PUCCH is located is different from the high-level signaling identifier of the PUCCH;

step 2E02, the terminal is configured by the higher layer to separate the feedback;

and step 2E03, the terminal determines that the current event is an error event and abandons sending the PUCCH.

In this example, the terminal determines that the event is an error event according to the situation of the high-level signaling identifier collision, and abandons sending the PUCCH, so that PUCCH configuration confusion caused by the signaling identifier collision is avoided, and the reliability and robustness of transmission are improved.

Referring to fig. 3, in accordance with the embodiment shown in fig. 2A, fig. 3 is a schematic structural diagram of a terminal 300 according to an embodiment of the present application, and as shown in the figure, the terminal 300 includes a processor 310, a memory 320, a communication interface 330, and one or more programs 321, where the one or more programs 321 are stored in the memory 320 and configured to be executed by the processor 310, and the one or more programs 321 include instructions for performing the following operations.

Detecting that a high-level signaling identifier of a control resource set CORESET where a physical downlink control channel PDCCH for scheduling a physical uplink control channel PUCCH is located is different from a high-level signaling identifier of the PUCCH; and determining that the current PUCCH sending event is responded by adopting a preset mode, wherein the preset mode is a response strategy agreed by a protocol.

It can be seen that, in the embodiment of the present application, when detecting that a high-level signaling identifier of a control resource set CORESET where a physical downlink control channel PDCCH for scheduling a physical uplink control channel PUCCH is located is different from a high-level signaling identifier of the PUCCH, a terminal may respond to the current PUCCH transmission event in a preset manner, where the preset manner is a response policy agreed by a protocol. Therefore, the terminal can solve the problem of how the terminal configures the PUCCH for transmission under the condition of high-level signaling mark conflict, and the reliability and robustness of transmission are improved.

In one possible example, the preset mode includes any one or more of the following combinations: ignoring the spatial information configured by the PUCCH at the high layer, and sending the PUCCH by adopting the spatial information related to the spatial information of the CORESET where the PDCCH is located; transmitting the PUCCH according to the spatial domain information configured by the PUCCH high layer; forgoing transmission of the PUCCH; and determining that the current event is an error event, and giving up sending the PUCCH.

In one possible example, the preset mode includes ignoring spatial information configured by the high layer of the PUCCH, and transmitting the PUCCH by using spatial information associated with spatial information of a CORESET where the PDCCH is located; before the terminal determines that the PUCCH sending event of this time is responded in a preset mode, the terminal is configured to joint feedback by a high layer; alternatively, the terminal is configured by a higher layer to separate the feedback.

In one possible example, the preset mode comprises transmitting the PUCCH according to spatial information configured by the PUCCH higher layer; before the terminal determines that the PUCCH sending event of this time is responded in a preset mode, the terminal is configured to joint feedback by a high layer; alternatively, the terminal is configured by a higher layer to separate the feedback.

In one possible example, the preset manner includes abandoning to transmit the PUCCH; before the terminal determines that the PUCCH sending event is responded by adopting a preset mode, the terminal is configured to be not responded by a high-level signaling identification conflict by a high-level; alternatively, the terminal is configured by a higher layer to separate the feedback.
