[0001] Cross-reference to related applications

[0002] This disclosure claims priority to Chinese patent application 201910657447.9, filed on July 19, 2019, entitled “PUCCH transmission, information configuration method and apparatus”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure belongs to the field of communication technology, and in particular relates to a PUCCH transmission, information configuration method and device. Background Technology

[0004] In 5G mobile communication systems, after receiving the Physical Downlink Shared Channel (PDSCH), the User Equipment (UE) needs to utilize the Physical Uplink Controlled Channel (PUCCH) resources configured by the network equipment to send a Hybrid Automatic Repeat Request ACK (HARQ-ACK) message back to the network equipment. Furthermore, before using the PUCCH resources to send HARQ-ACK information, it is necessary to determine relevant parameters of the PUCCH resources, such as the spatial relation information (beam information used to characterize the PUCCH) and power control parameters, and use these parameters to send HARQ-ACK messages on the PUCCH resources.

[0005] In related technologies, each PUCCH resource cannot have multiple active spatial relationship information or other parameters. Even if a PUCCH resource is allowed to have at least one active parameter, it is uncertain which parameter will be used to send the PUCCH on that PUCCH resource.

[0006] Application content

[0007] This disclosure provides a PUCCH transmission and information configuration method and apparatus, which allows a PUCCH resource to have at least one activation parameter, and selects one activation parameter from the at least one activation parameter as the target parameter used when transmitting PUCCH on the PUCCH resource to ensure that the PUCCH is transmitted correctly.

[0008] Firstly, a PUCCH transmission method is provided for use in a terminal device, the method comprising:

[0009] Under the condition of satisfying the first preset condition, the target parameter used when sending PUCCH on the target PUCCH resource is determined.

The target PUCCH resource has at least one activation parameter. The target parameter is one of the at least one activation parameter. The activation parameter includes at least one of activated spatial relationship information and power control parameters.

[0016] The PUCCH sending module is used to send PUCCH on a target PUCCH resource using target parameters.

[0017] Fourthly, a network device is provided, the network device comprising:

[0018] The first sending module is used to send first information to the terminal device;

[0019] Wherein, the first information is used by the terminal device to determine at least one activation parameter of the target PUCCH resource; or, the first information is used by the terminal device to determine the activation parameter of at least one PUCCH resource group to which the target PUCCH resource belongs, and the activation parameters of different PUCCH resource groups to which the target PUCCH resource belongs are different; the activation parameter includes at least one of activation spatial relationship information and power control parameters.

[0020] Fifthly, a terminal device is provided, the terminal device including a memory, a processor, and a wireless communication program stored in the memory and executable on the processor, wherein the wireless communication program, when executed by the processor, implements the steps of the method described in the first aspect.

[0023] The eighth invention provides a computer program product that, when a computer runs the instructions of the computer program product, executes the method described in the first aspect or the second aspect.

[0024] In this embodiment of the disclosure, a PUCCH resource is allowed to have at least one activation parameter, and an activation parameter is selected from the at least one activation parameter as the target parameter used when sending PUCCH on the PUCCH resource.

[0040] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0041] It should be understood that the technical solutions of the embodiments of this disclosure can be applied to various communication systems, such as: Global System of Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD) system, Universal Mobile Telecommunication System (UMTS) or Worldwide Interoperability for Microwave Access (WiMAX) communication system, 5G system, or New Radio (NR) system.

[0042] The UE, also known as a mobile terminal or mobile terminal device, can communicate with at least one core network via a radio access network (e.g., a radio access network, RAN). The terminal device can be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal, for example, a portable, pocket, handheld, computer-embedded, or vehicle-mounted mobile device. They exchange voice and / or data with the radio access network.

[0043] A network device is a device deployed in a wireless access network for configuring information. A network device can be a base station, which can be a base station (BTS) in GSM or CDMA, a base station (NodeB) in WCDMA, an evolved Node B (eNB or e-NodeB) in LTE, a 5G base station (gNB), and network-side equipment in subsequent evolved communication systems. However, the terminology used does not constitute a limitation on the scope of protection of this disclosure.

[0044] It should be noted that, in describing specific embodiments, the sequence number of each process does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this disclosure.

[0045] As shown in Figure 1, an embodiment of this disclosure provides a PUCCH transmission method that can be applied to a terminal device. The method may include the following steps:

[0046] Step 101: Under the condition of satisfying the first preset condition, determine the target parameter used when sending PUCCH on the target PUCCH resource. The target PUCCH resource has at least one activation parameter, and the target parameter is one of the at least one activation parameter.

[0047] The target PUCCH resource can be any PUCCH resource configured by the network device for the terminal device. Activation parameters include, but are not limited to, at least one of activated spatial relation information and activated power control parameters. The power control parameters may include, but are not limited to, pathloss reference signals (pathloss RS).

[0048] The target PUCCH resource may have at least one active spatial relation information, such as spatial relation 1 and spatial relation 2; and / or, the target PUCCH resource may have at least one active power control parameter, such as pathloss reference signals, pathloss RS 1 and pathloss reference signals, pathloss RS 2. When it is necessary to transmit a PUCCH on the target PUCCH resource, a target spatial relation information for transmitting the PUCCH on the target PUCCH resource needs to be selected from at least one active spatial relation information, and a target power control parameter for transmitting the PUCCH on the target PUCCH resource needs to be selected from at least one active power control parameter.

[0049] The first preset condition includes, but is not limited to, one of the following three conditions:

[0050] The first method involves receiving a first downlink control information (DCI) from a Transmission Reception Point (TRP). The first DCI is used to instruct the transmission of a PUCCH at the target PUCCH resource.

[0051] The second method involves receiving multiple DCIs from multiple TRPs, with the multiple DCIs used to instruct the sending of a PUCCH at the target PUCCH resource.

[0052] The third scenario is when the time arrives to send a PUCCH using the target PUCCH resource, which is either a periodic resource or a semi-persistent resource.

[0053] It is understandable that the three first preset conditions mentioned above correspond to three different application scenarios.

[0054] In the three different application scenarios described above, the determination of the target parameters used when sending PUCCH on the target PUCCH resource in step 101 includes:

[0055] Select one activation parameter from at least one activation parameter as the target parameter to be used when sending a PUCCH on the target PUCCH resource.

[0056] For example, a spatial relation information is selected from at least one active spatial relation information as the target spatial relation information for transmitting PUCCH on the target PUCCH resource; and / or, a power control parameter is selected from at least one active power control parameter as the target power control parameter for transmitting PUCCH on the target PUCCH resource. Several examples are provided below to illustrate this.

[0057] First example

[0058] Selecting an activation parameter from at least one set of activation parameters as the target parameter to be used when sending a PUCCH on the target PUCCH resource may include:

[0059] If the PUCCH resource is not grouped, the first activation parameter of at least one activation parameter is determined as the target parameter to be used when sending PUCCH on the target PUCCH resource.

[0060] That is, when the PUCCH resource is not grouped, the default activation parameter of at least one activation parameter of the target PUCCH resource is determined as the target parameter used when sending PUCCH on the target PUCCH resource.

[0061] The first activation parameter can be one of the following activation parameters:

[0062] (1) Activation parameters that correspond to the first specified TRP.

[0063] That is, if at least one activation parameter of the target PUCCH resource corresponds to a TRP, the activation parameter corresponding to the first specified TRP will be used as the first activation parameter.

[0064] In the first application scenario described above, that is, when the first preset condition includes receiving the first DCI from a TRP, the first designated TRP is the TRP that sent the first DCI.

[0065] For example, suppose the target PUCCH resource has two active spatial relation information: spatial relation 1 and spatial relation 2, where spatial relation 1 corresponds to TRP1 and spatial relation 2 corresponds to TRP2. Then, when the first DCI indicating the transmission of PUCCH on the target PUCCH resource is received from TRP1, TRP1 can be used as the first designated TRP. Accordingly, spatial relation 1 corresponding to TRP1 is used as the first active parameter.

[0066] In the second application scenario described above, that is, when the first preset condition includes receiving multiple DCIs from multiple TRPs, the first designated TRP is the TRP among the multiple TRPs that has a first preset identifier. The first preset identifier can be the identifier with the smallest index value, the identifier with the largest index value, the identifier with a preset index value, etc.

[0067] For example, suppose the target PUCCH resource has two active spatial relation information: spatial relation 1 and spatial relation 2, where spatial relation 1 corresponds to TRP1 and spatial relation 2 corresponds to TRP2. Then, when two DCIs from TRP1 and TRP2 are received, the TRP with the smallest index value between TRP1 and TRP2 (TRP1) can be determined as the first designated TRP. Accordingly, spatial relation 1 corresponding to TRP1 is used as the first activation parameter.

[0068] In the third application scenario described above, that is, when the first preset condition includes reaching the time to send a PUCCH using the target PUCCH resource, and the target PUCCH resource is a periodic resource or a semi-persistent resource, the first designated TRP is the TRP corresponding to the terminal device's most recent transmission. The most recent transmission includes one of the following: the most recent arbitrary transmission, the most recent arbitrary downlink transmission, the most recent arbitrary uplink transmission, the most recent designated channel, and the most recent designated signal.

[0069] Among them, the most recent arbitrary transmission refers to the transmission that is most recent to the current time among all transmissions (all channels and signals) that have occurred, and this transmission can be of any type; the most recent arbitrary downlink transmission refers to the downlink transmission that is most recent to the current time among all downlink transmissions (all downlink channels and signals) that have occurred, and this downlink transmission can be of any type; the most recent arbitrary uplink transmission refers to the uplink transmission that is most recent to the current time among all uplink transmissions (all uplink channels and signals) that have occurred, and this uplink transmission can be of any type; the most recent specified channel refers to the channel transmission of a specified type (such as PDCCH) that is most recent to the current time among all channel transmissions that have occurred; and the most recent specified signal refers to the signal transmission of a specified type that is most recent to the current time among all signal transmissions that have occurred.

[0070] For example, suppose the target PUCCH resource has two active spatial relation information: spatial relation 1 and spatial relation 2, where spatial relation 1 corresponds to TRP1, spatial relation 2 corresponds to TRP2, and the most recent transmission is the most recent PDCCH. Then, when the time arrives to send a PUCCH on the target PUCCH resource, if the TRP corresponding to the most recent PDCCH is TRP2, TRP2 can be determined as the first specified TRP. Accordingly, spatial relation 2 corresponding to TRP2 is used as the first activation parameter.

[0071] It should be noted that, in this embodiment of the disclosure, a TRP can be identified by at least one of the following information:

[0072] Control resource set or control resource set group;

[0073] The index value (ID) is a TRP method for explicit identification;

[0074] Transmission Configuration Indicator (TCI) status, TCI status list, or TCI status pool;

[0075] Quasi Co-location (QCL) information or QCL group information;

[0076] Spatial relation information or spatial relation group information;

[0077] PDCCH scrambling identifier or PDCCH scrambling identifier group;

[0078] PDSCH scrambling identifier or PDSCH scrambling identifier group;

[0079] PDCCH configures signaling elements;

[0080] PDSCH configures signaling elements;

[0081] Reference Signals (RS) resources or RS resource sets.

[0082] (2) Activation parameters that correspond to the first specified object, wherein the first specified object includes one of the specified resource, the specified channel and the specified signal, and the value of the first preset parameter of the first specified object meets the second preset condition.

[0083] That is, if at least one activation parameter of the target PUCCH resource corresponds to a specified object, the activation parameter corresponding to the first specified object is used as the first activation parameter.

[0084] In the first application scenario described above, that is, when the first preset condition includes receiving the first DCI from a TRP, the first designated object can be the designated object of the TRP that sent the first DCI, such as the designated channel, designated signal, or control resource set (CORESET) group of the TRP that sent the first DCI.

[0085] For example, suppose the target PUCCH resource has two active spatial relation information: spatial relation 1 and spatial relation 2, where spatial relation 1 corresponds to CORESET group 1 and spatial relation 2 corresponds to CORESET group 2. Then, when the first DCI is received from TRP1, and the control resource set group of TRP1 is CORESET group 1, CORESET group 1 can be used as the first designated object. Accordingly, spatial relation 1 corresponding to CORESET group 1 is used as the first activation parameter.

[0086] In the second application scenario described above, that is, when the first preset condition includes receiving multiple DCIs from multiple TRPs, the first designated object is the control resource set whose group identifier meets the second preset condition among the multiple control resource sets where the multiple DCIs are located.

[0087] The second preset condition may include, but is not limited to, at least one of the following: minimum group identifier, maximum group identifier, and group identifier being a preset value.

[0088] For example, suppose the target PUCCH resource has two active spatial relation information: spatial relation 1 and spatial relation 2, where spatial relation 1 corresponds to CORESET group 1 and spatial relation 2 corresponds to CORESET group 2. Then, when two DCIs are received from TRP1 and TRP2, and one DCI belongs to control resource group 1 while the other belongs to control resource group 2, the DCI with the smallest index value in CORESET group 1 can be identified as the first designated object. Accordingly, spatial relation 1 corresponding to CORESET group 1 is used as the first activation parameter.

[0089] In the third application scenario described above, that is, when the first preset condition includes reaching the time to send a PUCCH using the target PUCCH resource, and the target PUCCH resource is a periodic resource or a semi-persistent resource, the first designated object can be the control resource set corresponding to the most recent transmission of the terminal device. The most recent transmission includes one of the following: the most recent arbitrary transmission, the most recent arbitrary downlink transmission, the most recent arbitrary uplink transmission, the most recent designated channel, and the most recent designated signal.

[0090] For example, suppose the target PUCCH resource has two active spatial relation information: spatial relation 1 and spatial relation 2, where spatial relation 1 corresponds to CORESET group 1 and spatial relation 2 corresponds to CORESET group 2, and the most recent transmission is the most recent PDCCH. Then, when the time arrives to send a PUCCH on the target PUCCH resource, if the control resource set group corresponding to the most recent PDCCH is CORESET group 2, CORESET group 2 can be identified as the first designated object. Accordingly, spatial relation 2 corresponding to CORESET group 2 is used as the first activation parameter.

[0091] (3) The value of the second preset parameter meets the activation parameter of the third preset condition.

[0092] The second preset parameter includes RS, and the value of the second preset parameter includes at least one of the type and index value of the reference signal; or, the second preset parameter includes a source reference signal (source RS), and the value of the second preset parameter includes at least one of the type and index value of the source reference signal.

[0093] For example, suppose the target PUCCH resource has two active spatial relation information: spatial relation 1 and spatial relation 2, where the reference signal of spatial relation 1 is Synchronization Signal Block (SSB) 1, and the reference signal of spatial relation 2 is SSB 2. Then, the spatial relation information corresponding to the reference signal with the smallest index value between SSB1 and SSB2 can be determined as the first activation parameter, that is, spatial relation 1 corresponding to SSB1 can be determined as the first activation parameter.

[0094] For example, suppose the target PUCCH resource has two active spatial relation information: spatial relation 1 and spatial relation 2, where the reference signal for spatial relation 1 is SSB 1, and the reference signal for spatial relation 2 is Channel State Information-Reference Signals (CSI-RS) 2. Then, the spatial relation information corresponding to the reference signal of type CSI-RS with the largest index value can be determined as the first activation parameter, that is, spatial relation 2 corresponding to CSI-RS 2 can be determined as the first activation parameter.

[0095] The second example

[0096] Selecting an activation parameter from at least one set of activation parameters as the target parameter to be used when sending a PUCCH on the target PUCCH resource may include:

[0097] When a PUCCH resource is grouped, the second activation parameter from at least one activation parameter is determined as the target parameter used when sending a PUCCH on the target PUCCH resource. The second activation parameter specifies the activation parameter of the PUCCH resource group, indicating that the target PUCCH resource is included in the PUCCH resource group.

[0098] That is, when PUCCH resources are grouped, the activation parameter of the specified PUCCH resource group in at least one PUCCH resource group to which the target PUCCH resource belongs is determined as the target parameter used when sending PUCCH on the target PUCCH resource.

[0099] The specified PUCCH resource group can be one of the following PUCCH resource groups:

[0100] (1) Group identifiers that meet the fourth preset condition for PUCCH resource groups.

[0101] In other words, the specified PUCCH resource group can be any PUCCH resource group whose group identifier satisfies the fourth preset condition among multiple PUCCH resource groups to which the target PUCCH resource belongs. The fourth preset condition may include one of the following: the group identifier is the largest, the group identifier is the smallest, or the group identifier is a preset value.

[0102] (2) PUCCH resource group that corresponds to the second designated TRP.

[0103] That is, when multiple PUCCH resource groups to which the target PUCCH resource belongs have a corresponding relationship with the TRP, the PUCCH resource group corresponding to the second specified TRP will be used as the specified PUCCH resource group.

[0104] In the first application scenario described above, that is, when the first preset condition includes receiving the first DCI from a TRP, the second designated TRP is the TRP that sent the first DCI.

[0105] For example, suppose the target PUCCH resource belongs to two PUCCH resource groups: PUCCH resource group 1 and PUCCH resource group 2, where PUCCH resource group 1 corresponds to TRP1 and PUCCH resource group 2 corresponds to TRP2. Then, when a first DCI indicating that a PUCCH should be sent on the target PUCCH resource is received from TRP1, TRP1 can be designated as the second specified TRP. Accordingly, PUCCH resource group 1 corresponding to TRP1 is designated as the specified PUCCH resource group.

[0106] In the second application scenario described above, that is, when the first preset condition includes receiving multiple DCIs from multiple TRPs, the second designated TRP is the TRP among the multiple TRPs that has a second preset identifier. The second preset identifier can be the identifier with the smallest index value, the identifier with the largest index value, the identifier with a preset index value, etc.

[0107] For example, suppose the target PUCCH resource belongs to two PUCCH resource groups: PUCCH resource group 1 and PUCCH resource group 2, where PUCCH resource group 1 corresponds to TRP1 and PUCCH resource group 2 corresponds to TRP2. Then, when two DCIs are received from TRP1 and TRP2, the TRP with the smallest index value (TRP1) can be determined as the second designated TRP. Accordingly, PUCCH resource group 1 corresponding to TRP1 is designated as the specified PUCCH resource group.

[0108] In the third application scenario described above, that is, when the first preset condition includes the arrival of the time to send a PUCCH using the target PUCCH resource, and the target PUCCH resource is a periodic resource or a semi-persistent resource, the second specified TRP is the TRP corresponding to the terminal device's most recent transmission. The most recent transmission includes one of the following: the most recent arbitrary transmission, the most recent arbitrary downlink transmission, the most recent arbitrary uplink transmission, the most recent specified channel, and the most recent specified signal.

[0109] For example, suppose the target PUCCH resource belongs to two PUCCH resource groups: PUCCH resource group 1 and PUCCH resource group 2, where PUCCH resource group 1 corresponds to TRP1, PUCCH resource group 2 corresponds to TRP2, and the most recent transmission is the most recent arbitrary transmission. Then, when the time arrives to send a PUCCH on the target PUCCH resource, if the TRP corresponding to the most recent arbitrary transmission is TRP2, then TRP2 can be determined as the second designated TRP. Accordingly, PUCCH resource group 2 corresponding to TRP2 is designated as the designated PUCCH resource group.

[0110] (3) A PUCCH resource group that corresponds to the second specified object. The specified object includes one of the specified resource, specified channel and specified signal, and the value of the third preset parameter of the second specified object meets the fifth preset condition.

[0111] For example, when the second specified object is a specified control resource group and the third preset parameter is the group identifier of the control resource group, the fifth preset condition includes at least one of the following conditions: the group identifier is the smallest, the group identifier is the largest, and the group identifier is a preset value.

[0112] In the first application scenario described above, that is, when the first preset condition includes receiving the first DCI from a TRP, the second specified object is the control resource set group where the first DCI is located.

[0113] For example, suppose the target PUCCH resource belongs to two PUCCH resource groups: PUCCH resource group 1 and PUCCH resource group 2, where PUCCH resource group 1 corresponds to CORESET group 1, and PUCCH resource group 2 corresponds to CORESET group 2, and the control resource set group of TRP1 is CORESET group 1, and the control resource set group of TRP2 is CORESET group 2. Then, when the first DCI is received from TRP1, CORESET group 1, where the first DCI is located, can be identified as the second designated object. Accordingly, PUCCH resource group 1 corresponding to CORESET group 1 is designated as the specified PUCCH resource group.

[0114] In the second application scenario described above, that is, when the first preset condition includes receiving multiple DCIs from multiple TRPs, the second designated object is the control resource set whose group identifier meets the fifth preset condition among the multiple control resource sets where the multiple DCIs are located.

[0115] For example, suppose the target PUCCH resource belongs to two PUCCH resource groups: PUCCH resource group 1 and PUCCH resource group 2, where PUCCH resource group 1 corresponds to CORESET group 1 and PUCCH resource group 2 corresponds to CORESET group 2, and the control resource set groups to which the multiple DCIs belong include CORESET group 1 and CORESET group 2. Then, when multiple DCIs are received from TRP1 and TRP2, CORESET group 1, which contains the smallest group identifier (group ID) among CORESET group 1 and CORESET group 2, can be identified as the second designated object. Accordingly, PUCCH resource group 1 corresponding to CORESET group 1 is designated as the specified PUCCH resource group.

[0116] In the third application scenario described above, where the first preset condition includes the arrival of the time to send a PUCCH using the target PUCCH resource, and the target PUCCH resource is a periodic resource or a semi-persistent resource, the second specified object is the control resource set corresponding to the terminal device's most recent transmission. The most recent transmission includes one of the following: the most recent arbitrary transmission, the most recent arbitrary downlink transmission, the most recent arbitrary uplink transmission, the most recent specified channel, and the most recent specified signal.

[0117] For example, suppose the target PUCCH resource belongs to two PUCCH resource groups: PUCCH resource group 1 and PUCCH resource group 2, where PUCCH resource group 1 corresponds to CORESET group 1, and PUCCH resource group 2 corresponds to CORESET group 2. The most recent transmission is the most recent downlink channel, and the control resource set corresponding to the most recent downlink channel is CORESET group 2. Then, when the time comes to transmit a PUCCH on the target PUCCH resource, CORESET group 2 can be identified as the second designated object. Accordingly, PUCCH resource group 2 corresponding to CORESET group 2 is designated as the specified PUCCH resource group.

[0118] The first and second examples above illustrate that a terminal device can select an activation parameter from at least one activation parameter according to certain rules (which may be fixed in the protocol) as the target parameter used when transmitting a PUCCH on a target PUCCH resource. This eliminates the need for network devices to individually configure or indicate the target parameter for each PUCCH resource, thus reducing network resource overhead. Furthermore, it ensures that network devices and terminal devices have a consistent understanding of the parameters used for PUCCH transmission, thereby guaranteeing correct PUCCH transmission and improving communication reliability.

[0119] The third example

[0120] When the target PUCCH resource has at least one activation parameter, selecting one activation parameter from the at least one activation parameter as the target parameter used when sending PUCCH on the target PUCCH resource may include: selecting one activation parameter from the at least one activation parameter as the target parameter used when sending PUCCH on the target PUCCH resource based on third information from the network device.

[0121] In other words, in addition to selecting an activation parameter from at least one activation parameter according to certain rules in the first and second examples above, as the target parameter used when sending PUCCH on the target PUCCH resource, an activation parameter can also be selected from at least one activation parameter according to the instructions of the network device, as the target parameter used when sending PUCCH on the target PUCCH resource.

[0122] The third piece of information can be either the second DCI or the second MAC CE. Here, MAC CE refers to the Media Access Control Element (MAC CE).

[0123] It should be noted that the second DCI can be a DCI with a newly defined signaling field added to an existing DCI format, or it can be a newly added DCI with a dedicated DCI format, which is specifically used to indicate the target parameters used when sending PUCCH on the target PUCCH resource.

[0124] The third example above can also ensure that network devices and terminal devices have a consistent understanding of the parameters used in PUCCH transmission, thereby guaranteeing that PUCCH is transmitted correctly and improving communication reliability.

[0125] The fourth example

[0126] In the third application scenario described above, that is, when the first preset condition includes reaching the time to send a PUCCH using the target PUCCH resource, and the target PUCCH resource is a periodic resource or a semi-persistent resource, the target parameters used in step 101 for determining the PUCCH sent on the target PUCCH resource include:

[0127] According to the period of the target PUCCH resource, one of the at least one activation parameter is selected in turn as the target parameter used when sending PUCCH on the target PUCCH resource.

[0128] For example, if the period of the target PUCCH resource is 20ms and the target PUCCH resource has two activation parameters, such as spatial relation1 and spatial relation2, then spatial relation1 can be used as the target spatial relation in the first period, spatial relation2 in the second period, spatial relation1 in the third period, spatial relation2 in the fourth period, and so on.

[0129] The fourth example above can also be understood as the terminal device selecting an activation parameter from at least one activation parameter according to certain rules (which can be fixed in the protocol) as the target parameter used when sending PUCCH on the target PUCCH resource. This eliminates the need for the network device to configure or indicate the target parameter for each PUCCH resource individually, thus reducing network resource overhead. Furthermore, it ensures that the network device and the terminal device have a consistent understanding of the parameters used for PUCCH transmission, thereby guaranteeing correct PUCCH transmission and improving communication reliability.

[0130] Step 102: Send PUCCH on the target PUCCH resource using the target parameters.

[0131] Specifically, based on the first example above, a PUCCH is sent to the target TRP using the target parameters on the target PUCCH resource.

[0132] For example, in the first application scenario described above, that is, when the first preset condition includes receiving the first DCI from a TRP, the target TRP is the TRP that sent the first DCI.

[0133] For example, in the second application scenario mentioned above, that is, when the first preset condition includes receiving multiple DCIs from multiple TRPs, the target TRP is one of the multiple TRPs that sent multiple DCIs that corresponds to the target parameter, such as the first designated TRP (when the PUCCH resource is not grouped) or the second designated TRP (when the PUCCH resource is grouped).

[0134] For example, in the third application scenario mentioned above, that is, when the first preset condition includes reaching the time to send a PUCCH using the target PUCCH resource, and the target PUCCH resource is a periodic resource or a semi-persistent resource, the target TRP is the TRP corresponding to the most recent transmission. The most recent downlink transmission includes one of the following: the most recent arbitrary transmission, the most recent arbitrary downlink transmission, the most recent arbitrary uplink transmission, the most recent specified channel, and the most recent specified signal, etc.

[0135] The PUCCH transmission method provided in this disclosure has several advantages. Firstly, since the terminal device can select an activation parameter from at least one activation parameter according to certain rules (which may be fixed in the protocol) as the target parameter for transmitting PUCCH on the target PUCCH resource, the network device does not need to configure or indicate the target parameter for each PUCCH resource individually, thus reducing network resource overhead. Secondly, when the target PUCCH resource has at least one activation parameter, one activation parameter can be selected as the target parameter for transmitting PUCCH on the target PUCCH resource. This ensures that the network device and the terminal device have a consistent understanding of the parameters used for PUCCH transmission, thereby guaranteeing correct PUCCH transmission and improving communication reliability.

[0136] Optionally, as shown in FIG2, the PUCCH transmission method provided in this embodiment of the present disclosure may further include one of the following steps before step 101:

[0137] Step 104: Receive second information from the network device. The second information is used to configure at least one parameter for the target PUCCH resource or at least one PUCCH resource group. The at least one parameter includes at least one activation parameter.

[0138] The second piece of information can be Radio Resource Control (RRC) information. That is, the network device uses RRC information to configure at least one spatial relation information for the target PUCCH resource, and / or configure at least one power control parameter (such as pathloss RS) for the target PUCCH resource.

[0139] Step 103: Determine at least one activation parameter of the target PUCCH resource based on the first information from the network device; wherein the first information is used to determine at least one activation parameter of the target PUCCH resource; or, the first information is used to determine the activation parameter of at least one PUCCH resource group to which the target PUCCH resource belongs, and the activation parameters of different PUCCH resource groups to which the target PUCCH resource belongs are different.

[0140] The first information can be either the first MAC CE or the first RRC information.

[0141] It is understood that the first information can be used to indicate at least one activation parameter of the target PUCCH resource to the terminal device for the first time, or to indicate at least one activation parameter from at least one parameter configured by the second information, or to update at least one activation parameter that has already been indicated for the target PUCCH resource.

[0142] For example, the network device indicates / updates multiple active spatial relation information for the target PUCCH resource through the first MAC CE, and / or the network device indicates / updates multiple active power control parameters for the target PUCCH resource through the first MAC CE. In specific implementations, the first MAC CE can be an existing MAC CE, and uses its existing reserved bits to indicate / update at least one active parameter of the target PUCCH resource. Optionally, the MAC CE can specifically be a MAC CE used in related technologies to indicate / update an active parameter for the target PUCCH resource; or, the first MAC CE can be a newly added MAC CE dedicated to indicating at least one active parameter.

[0143] When PUCCH resources are grouped, and the target PUCCH resource belongs to at least one PUCCH resource group, the network device can indicate / update multiple active spatial relation information for each PUCCH resource group through the first MAC CE, and / or, the network device can indicate / update multiple active power control parameters for each PUCCH resource group through the first MAC CE.

[0144] It is understood that when a target PUCCH resource belongs to multiple PUCCH resource groups, and the network device indicates / updates an activation parameter for each of these multiple PUCCH resource groups, the target PUCCH resource will have multiple activation parameters. That is, in this embodiment of the disclosure, a PUCCH resource is allowed to have multiple activation parameters.

[0145] Optionally, as shown in FIG3, the PUCCH transmission method provided in this embodiment of the present disclosure may further include the following before step 101:

[0146] Step 105: Receive the fourth message from the network device.

[0147] Step 106: Based on the fourth information, determine the PUCCH resource group to which the target PUCCH resource belongs.

[0148] In the first embodiment of this example, the fourth information can be RRC information. This fourth information is used to configure the target PUCCH resource for the terminal device, and it includes first target information used to determine the PUCCH resource group to which the target PUCCH resource belongs. In other words, the target PUCCH resource can be grouped by configuring its RRC information for the terminal device.

[0149] The first target information may include any one of the following:

[0150] The identification information of the PUCCH resource group to which the target PUCCH resource belongs;

[0151] The identification information of the TRP corresponding to the target PUCCH resource;

[0152] Identification information of the control resource set group corresponding to the target PUCCH resource.

[0153] This information can be used to indicate the PUCCH resource group to which the target PUCCH resource belongs.

[0154] For example, a PUCCH resource group's group ID can be added to the PUCCH-config parameter in the RRC information; alternatively, a new parent parameter of PUCCH-config can be added to indicate the PUCCH resource group's group ID, and under this new parent parameter, the PUCCH resource information belonging to that group can be indicated. Optionally, the PUCCH resource group's group ID can also be identified by TRP ID, CORESET group ID, etc.

[0155] In the second embodiment of this example, the fourth information is RRC information. Based on the fourth information, the PUCCH resource group to which the target PUCCH resource belongs is determined, including:

[0156] Based on the identification information of the Band Width Part (BWP) in the RRC information, determine the PUCCH resource group to which the target PUCCH resource belongs. PUCCH resources under the same BWP belong to the same PUCCH resource group.

[0157] This implementation is intended to illustrate that when all PUCCH resources within a BWP are grouped together, the group information of the PUCCH resources can be determined through the BWP's identification information instead of being explicitly configured by RRC information.

[0158] In the third embodiment of this example, the fourth information is one of the following: the third MAC CE and the fourth MAC CE.

[0159] The third MAC CE is used to group PUCCH resources, and it contains the second target information. For example, an existing MAC CE can be used as the third MAC CE to indicate the group information of the PUCCH resource group to which the target PUCCH resource belongs, and / or to indicate the PUCCH resource information included in that PUCCH resource group. Alternatively, a newly added MAC CE can be used as the third MAC CE to indicate the group information of the PUCCH resource group to which the target PUCCH resource belongs, and / or to indicate the PUCCH resource information included in that PUCCH resource group.

[0160] Furthermore, when using an existing MAC CE as the third MAC CE, at least one specific bit (such as a reserved bit) in the MAC CE can be used to explicitly indicate the group information of the target PUCCH resource; or, the group information of the target PUCCH resource can be implicitly indicated by existing bits contained in the MAC CE (such as the values ​​in the existing indication fields implicitly representing the group information).

[0161] The fourth MAC CE is used to indicate at least one activation parameter of the target PUCCH resource or the PUCCH resource group to which the target PUCCH resource belongs, and the fourth MAC CE contains second target information. That is, the grouping information of the target PUCCH resource can be indicated using a MAC CE indicating at least one activation parameter, and this fourth MAC CE can be the same MAC CE as the first MAC CE mentioned above. Optionally, the fourth MAC CE can be an existing MAC CE or a newly added MAC CE.

[0162] The second target information in the third MAC CE and the fourth MAC CE is used to determine the PUCCH resource group to which the PUCCH resource belongs.

[0163] The above describes the PUCCH transmission method applied to terminal devices. The following describes an information configuration method provided by an embodiment of this disclosure with reference to Figures 4 to 6.

[0164] As shown in Figure 4, an information configuration method provided in this embodiment of the present disclosure is applied to a network device. The method may include:

[0165] Step 401: Send first information to the terminal device; wherein the first information is used by the terminal device to determine at least one activation parameter of the target PUCCH resource; or, the first information is used by the terminal device to determine the activation parameter of at least one PUCCH resource group to which the target PUCCH resource belongs, and the activation parameters of different PUCCH resource groups to which the target PUCCH resource belongs are different; the activation parameter includes at least one of activation spatial relationship information and power control parameters.

[0166] The first information can be either the first MAC CE or the first RRC information.

[0167] It is understood that the first information can be used to indicate at least one activation parameter of the target PUCCH resource to the terminal device for the first time, or it can be used to update at least one activation parameter that has already been indicated for the target PUCCH resource.

[0168] For example, the network device indicates / updates multiple active spatial relation information for a target PUCCH resource through a first MAC CE, and / or the network device indicates / updates multiple active power control parameters for a target PUCCH resource through a first MAC CE. In specific implementations, the first MAC CE can be an existing MAC CE, and its existing reserved bits are used to indicate / update at least one active parameter of the target PUCCH resource. Optionally, the MAC CE can specifically be a MAC CE used in related technologies to indicate / update an active parameter for a target PUCCH resource; or, the first MAC CE can be a newly added MAC CE dedicated to indicating at least one active parameter.

[0169] When PUCCH resources are grouped, and the target PUCCH resource belongs to at least one PUCCH resource group, the network device can indicate / update multiple active spatial relation information for each PUCCH resource group through the first MAC CE, and / or, the network device can indicate / update multiple active power control parameters for each PUCCH resource group through the first MAC CE.

[0170] It is understood that when a target PUCCH resource belongs to multiple PUCCH resource groups, and the network device indicates / updates an activation parameter for each of these multiple PUCCH resource groups, the target PUCCH resource will have multiple activation parameters. That is, in this embodiment of the disclosure, a PUCCH resource is allowed to have multiple activation parameters.

[0171] Optionally, as shown in FIG5, an information configuration method provided in this embodiment of the present disclosure may further include, before step 401:

[0172] Step 402: Send second information to the terminal device; wherein the second information is used to configure at least one parameter for the target PUCCH resource or at least one PUCCH resource group, and at least one parameter includes at least one activation parameter.

[0173] The second piece of information can be RRC information. That is, the network device configures at least one spatial relation information for the target PUCCH resource through RRC information, and / or configures at least one or more active power control parameters (such as RS) for the target PUCCH resource.

[0174] Optionally, as shown in FIG5, the information configuration method provided in this embodiment of the present disclosure may further include, after step 401:

[0175] Step 403: Send third information to the terminal device; wherein the third information is used by the terminal device to select an activation parameter from at least one activation parameter as the target parameter used when sending PUCCH on the target PUCCH resource.

[0176] The third information can be either the second DCI or the second MAC CE.

[0177] It should be noted that the second DCI can be a DCI with a newly defined signaling field added to an existing DCI format, or it can be a newly added DCI with a dedicated DCI format, which is specifically used to indicate the target parameters used when sending PUCCH on the target PUCCH resource.

[0178] Optionally, as shown in FIG6, an information configuration method provided in this embodiment of the present disclosure may further include, before step 401:

[0179] Step 404: Send fourth information to the terminal device; wherein, the fourth information is used by the terminal device to determine the PUCCH resource group to which the target PUCCH resource belongs.

[0180] In the first embodiment of this example, the fourth information can be RRC information. This fourth information is used to configure the target PUCCH resource for the terminal device, and it includes first target information used to determine the PUCCH resource group to which the target PUCCH resource belongs. In other words, the target PUCCH resource can be grouped by configuring its RRC information for the terminal device.

[0181] The first target information may include any one of the following:

[0182] The identification information of the PUCCH resource group to which the target PUCCH resource belongs;

[0183] The identification information of the TRP corresponding to the target PUCCH resource;

[0184] Identification information of the control resource set group corresponding to the target PUCCH resource.

[0185] This information can be used to indicate the PUCCH resource group to which the target PUCCH resource belongs.

[0186] For example, a PUCCH resource group's group ID can be added to the PUCCH-config parameter in the RRC information; alternatively, a new parent parameter of PUCCH-config can be added to indicate the PUCCH resource group's group ID, and under this new parent parameter, the PUCCH resource information belonging to that group can be indicated. Optionally, the PUCCH resource group's group ID can also be identified by TRP ID, CORESET group ID, etc.

[0187] In the second embodiment of this example, the fourth information is RRC information, in which the BWP identification information can be used to determine the PUCCH resource group to which the target PUCCH resource belongs, and PUCCH resources under the same BWP belong to the same PUCCH resource group.

[0188] This implementation is intended to illustrate that when all PUCCH resources within a BWP are grouped together, the group information of the PUCCH resources can be determined through the BWP's identification information instead of being explicitly configured by RRC information.

[0189] In the third embodiment of this example, the fourth information is one of the following: the third MAC CE and the fourth MAC CE.

[0190] The third MAC CE is used to group PUCCH resources, and it contains the second target information. For example, an existing MAC CE can be used as the third MAC CE to indicate the group information of the PUCCH resource group to which the target PUCCH resource belongs, and / or to indicate the PUCCH resource information included in that PUCCH resource group. Alternatively, a newly added MAC CE can be used as the third MAC CE to indicate the group information of the PUCCH resource group to which the target PUCCH resource belongs, and / or to indicate the PUCCH resource information included in that PUCCH resource group.

[0191] Furthermore, when using an existing MAC CE as the third MAC CE, at least one specific bit (such as a reserved bit) in the MAC CE can be used to explicitly indicate the group information of the target PUCCH resource; or, the group information of the target PUCCH resource can be implicitly indicated by existing bits contained in the MAC CE (such as the values ​​in the existing indication fields implicitly representing the group information).

[0192] The fourth MAC CE is used to indicate at least one activation parameter of the target PUCCH resource or the PUCCH resource group to which the target PUCCH resource belongs, and the fourth MAC CE contains second target information. That is, the grouping information of the target PUCCH resource can be indicated using a MAC CE indicating at least one activation parameter, and this fourth MAC CE can be the same MAC CE as the first MAC CE mentioned above. Optionally, the fourth MAC CE can be an existing MAC CE or a newly added MAC CE.

[0193] The second target information in the third MAC CE and the fourth MAC CE is used to determine the PUCCH resource group to which the PUCCH resource belongs.

[0194] The above describes the information configuration method applied to network devices. The terminal device and network device according to the embodiments of this disclosure will be described in detail below with reference to Figures 7 to 12.

[0195] Figure 7 shows a schematic diagram of the structure of a terminal device provided in an embodiment of the present disclosure. As shown in Figure 7, the terminal device 700 may include: a first determining module 701 and a PUCCH sending module 702.

[0196] The first determining module 701 is used to determine the target parameters used when transmitting PUCCH on the target PUCCH resource when a first preset condition is met. The target PUCCH resource has at least one activation parameter, and the target parameter is one of the at least one activation parameter. The activation parameter includes at least one of activated spatial relationship information and power control parameters.

[0197] The first preset condition includes, but is not limited to, one of the following three conditions:

[0198] The first method involves receiving a first DCI from a TRP, which instructs the target PUCCH resource to send a PUCCH.

[0199] The second method involves receiving multiple DCIs from multiple TRPs, with the multiple DCIs used to instruct the sending of a PUCCH at the target PUCCH resource.

[0200] The third scenario is when the time arrives to send a PUCCH using the target PUCCH resource, which is either a periodic resource or a semi-persistent resource.

[0201] It is understandable that the three first preset conditions mentioned above correspond to three different application scenarios.

[0202] In the three different application scenarios described above, the first determining module 701 can be used to: select an activation parameter from at least one activation parameter as the target parameter used when sending a PUCCH on the target PUCCH resource. Several examples are provided below to illustrate this.

[0203] First example

[0204] The first determining module 701 can be specifically used to: determine the first activation parameter among at least one activation parameter as the target parameter used when sending PUCCH on the target PUCCH resource when the PUCCH resource is not grouped.

[0205] The first activation parameter can be one of the following activation parameters:

[0206] (1) Activation parameters that correspond to the first specified TRP.

[0207] In the first application scenario described above, that is, when the first preset condition includes receiving the first DCI from a TRP, the first designated TRP is the TRP that sent the first DCI.

[0208] In the second application scenario described above, that is, when the first preset condition includes receiving multiple DCIs from multiple TRPs, the first designated TRP is the TRP with the first preset identifier among the multiple TRPs.

[0209] In the third application scenario described above, that is, when the first preset condition includes reaching the time to send a PUCCH using the target PUCCH resource, and the target PUCCH resource is a periodic resource or a semi-persistent resource, the first designated TRP is the TRP corresponding to the terminal device's most recent transmission. The most recent transmission includes one of the following: the most recent arbitrary transmission, the most recent arbitrary downlink transmission, the most recent arbitrary uplink transmission, the most recent designated channel, and the most recent designated signal.

[0210] (2) Activation parameters that correspond to the first specified object, wherein the first specified object includes one of the specified resource, the specified channel and the specified signal, and the value of the first preset parameter of the first specified object meets the second preset condition.

[0211] That is, if at least one activation parameter of the target PUCCH resource corresponds to a specified object, the activation parameter corresponding to the first specified object will be used as the first activation parameter.

[0212] In the first application scenario described above, that is, when the first preset condition includes receiving the first DCI from a TRP, the first specified object can be the specified object of the TRP that sent the first DCI, such as the specified channel, specified signal, or control resource set (CORESET) group of the TRP that sent the first DCI.

[0213] In the second application scenario described above, that is, when the first preset condition includes receiving multiple DCIs from multiple TRPs, the first designated object is the control resource set whose group identifier meets the second preset condition among the multiple control resource sets where the multiple DCIs are located.

[0214] The second preset condition may include, but is not limited to, at least one of the following: minimum group identifier, maximum group identifier, and group identifier being a preset value.

[0215] In the third application scenario described above, that is, when the first preset condition includes reaching the time to send a PUCCH using the target PUCCH resource, and the target PUCCH resource is a periodic resource or a semi-persistent resource, the first designated object can be the control resource set corresponding to the most recent transmission of the terminal device. The most recent transmission includes one of the following: the most recent arbitrary transmission, the most recent arbitrary downlink transmission, the most recent arbitrary uplink transmission, the most recent designated channel, and the most recent designated signal.

[0216] (3) The value of the second preset parameter meets the activation parameter of the third preset condition.

[0217] The second preset parameter includes RS, and the value of the second preset parameter includes at least one of the type and index value of the reference signal; or, the second preset parameter includes source RS, and the value of the second preset parameter includes at least one of the type and index value of the source reference signal.

[0218] The second example

[0219] The first determining module 701 is specifically used to: when PUCCH resources are grouped, determine a second activation parameter from at least one activation parameter as the target parameter used when sending a PUCCH on the target PUCCH resource. The second activation parameter is an activation parameter specifying a PUCCH resource group, indicating that the PUCCH resource group contains the target PUCCH resource.

[0220] That is, when PUCCH resources are grouped, the activation parameter of the specified PUCCH resource group in at least one PUCCH resource group to which the target PUCCH resource belongs is determined as the target parameter used when sending PUCCH on the target PUCCH resource.

[0221] The specified PUCCH resource group can be one of the following PUCCH resource groups:

[0222] (1) Group identifiers that meet the fourth preset condition for PUCCH resource groups.

[0223] In other words, the specified PUCCH resource group can be any PUCCH resource group whose group identifier satisfies the fourth preset condition among multiple PUCCH resource groups to which the target PUCCH resource belongs. The fourth preset condition may include one of the following: the group identifier is the largest, the group identifier is the smallest, or the group identifier is a preset value.

[0224] (2) PUCCH resource group that corresponds to the second designated TRP.

[0225] That is, when multiple PUCCH resource groups to which the target PUCCH resource belongs have a corresponding relationship with the TRP, the PUCCH resource group corresponding to the second specified TRP will be used as the specified PUCCH resource group.

[0226] In the first application scenario described above, that is, when the first preset condition includes receiving the first DCI from a TRP, the second designated TRP is the TRP that sent the first DCI (the TRP that sent the first DCI).

[0227] In the second application scenario described above, that is, when the first preset condition includes receiving multiple DCIs from multiple TRPs, the second designated TRP is the TRP among the multiple TRPs that has a second preset identifier. The second preset identifier can be the identifier with the smallest index value, the identifier with the largest index value, the identifier with a preset index value, etc.

[0228] In the third application scenario described above, that is, when the first preset condition includes the arrival of the time to send a PUCCH using the target PUCCH resource, and the target PUCCH resource is a periodic resource or a semi-persistent resource, the second specified TRP is the TRP corresponding to the terminal device's most recent transmission. The most recent transmission includes one of the following: the most recent arbitrary transmission, the most recent arbitrary downlink transmission, the most recent arbitrary uplink transmission, the most recent specified channel, and the most recent specified signal.

[0229] (3) A PUCCH resource group that corresponds to the second specified object. The specified object includes one of the specified resource, specified channel and specified signal, and the value of the third preset parameter of the second specified object meets the fifth preset condition.

[0230] For example, when the second specified object is a specified control resource group and the third preset parameter is the group identifier of the control resource group, the fifth preset condition includes at least one of the following conditions: the group identifier is the smallest, the group identifier is the largest, and the group identifier is a preset value.

[0231] In the first application scenario described above, that is, when the first preset condition includes receiving a first DCI from a TRP, the second designated object is the control resource set whose group identifier in the control resource set where the first DCI is located meets the fifth preset condition.

[0232] In the second application scenario described above, that is, when the first preset condition includes receiving multiple DCIs from multiple TRPs, the second designated object is the control resource set whose group identifier meets the fifth preset condition among the multiple control resource sets where the multiple DCIs are located.

[0233] In the third application scenario described above, that is, when the first preset condition includes reaching the time to send a PUCCH using the target PUCCH resource, and the target PUCCH resource is a periodic resource or a semi-persistent resource, the second specified object is the control resource set corresponding to the terminal device's most recent transmission. The most recent transmission includes one of the following: the most recent arbitrary transmission, the most recent arbitrary downlink transmission, the most recent arbitrary uplink transmission, the most recent specified channel, and the most recent specified signal.

[0234] The first and second examples above illustrate that a terminal device can select an activation parameter from at least one activation parameter according to certain rules (which may be fixed in the protocol) as the target parameter used when transmitting a PUCCH on a target PUCCH resource. This eliminates the need for network devices to individually configure or indicate the target parameter for each PUCCH resource, thus reducing network resource overhead. Furthermore, it ensures that network devices and terminal devices have a consistent understanding of the parameters used for PUCCH transmission, thereby guaranteeing correct PUCCH transmission and improving communication reliability.

[0235] The third example

[0236] When the target PUCCH resource has at least one activation parameter, the first determining module 701 can be specifically used to: select an activation parameter from at least one activation parameter based on third information from the network device, as the target parameter to be used when sending PUCCH on the target PUCCH resource.

[0237] In other words, in addition to selecting an activation parameter from at least one activation parameter according to certain rules in the first and second examples above, as the target parameter used when sending PUCCH on the target PUCCH resource, an activation parameter can also be selected from at least one activation parameter according to the instructions of the network device, as the target parameter used when sending PUCCH on the target PUCCH resource.

[0238] The third information can be either the second DCI or the second MAC CE.

[0239] The third example above can also ensure that network devices and terminal devices have a consistent understanding of the parameters used in PUCCH transmission, thereby guaranteeing that PUCCH is transmitted correctly and improving communication reliability.

[0240] The fourth example

[0241] In the third application scenario mentioned above, that is, when the first preset condition includes the time to send PUCCH using the target PUCCH resource, and the target PUCCH resource is a periodic resource or a semi-persistent resource, the first determining module 701 can be used to: select one of the activation parameters from at least one activation parameter in turn according to the period of the target PUCCH resource, as the target parameter used when sending PUCCH on the target PUCCH resource.

[0242] The fourth example above can also be understood as the terminal device selecting an activation parameter from at least one activation parameter according to certain rules (which can be fixed in the protocol) as the target parameter used when sending PUCCH on the target PUCCH resource. This eliminates the need for the network device to configure or indicate the target parameter for each PUCCH resource individually, thus reducing network resource overhead. Furthermore, it ensures that the network device and the terminal device have a consistent understanding of the parameters used for PUCCH transmission, thereby guaranteeing correct PUCCH transmission and improving communication reliability.

[0243] PUCCH sending module 702 is used to send PUCCH on a target PUCCH resource using target parameters.

[0244] Specifically, the PUCCH sending module 702 can be used to send a PUCCH to a target TRP on a target PUCCH resource using target parameters.

[0245] For example, in the first application scenario described above, the target TRP is the TRP that transmits the first DCI. As another example, in the second application scenario described above, the target TRP is one of the multiple TRPs that transmit multiple DCIs, corresponding to the target parameters, such as the first designated TRP (when the PUCCH resource is not packetized) or the second designated TRP (when the PUCCH resource is packetized). Furthermore, in the third application scenario described above, the target TRP is the TRP corresponding to the most recent transmission, where the most recent transmission includes any recent transmission, any recent downlink transmission, any recent uplink transmission, the most recent designated channel, and the most recent designated signal, etc.

[0246] The terminal device 700 provided in the embodiments of this specification, on the one hand, can reduce network resource overhead because it can select an activation parameter from at least one activation parameter according to certain rules (which may be fixed in the protocol) as the target parameter used when transmitting PUCCH on the target PUCCH resource, without requiring the network device to configure or indicate the target parameter separately for each PUCCH resource. On the other hand, when the target PUCCH resource has at least one activation parameter, one activation parameter can be selected as the target parameter used when transmitting PUCCH on the target PUCCH resource. This ensures that the network device and the terminal device have a consistent understanding of the parameters used for PUCCH transmission, thereby ensuring that the PUCCH is transmitted correctly and improving communication reliability.

[0247] Optionally, as shown in FIG8, a terminal device 700 provided in this embodiment of the present disclosure may further include:
