[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on September 26, 2022, with application number 202211177484.8 and application name “Capability Indication Method, Device, Terminal and Medium”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application belongs to the field of communication technology, and specifically relates to a capability indication method, device, terminal and medium. Background Art

[0003] Currently, in the New Radio (NR) system, if the network side device does not configure a dedicated physical uplink control channel (PUCCH) resource for the terminal, the terminal can use the common PUCCH resource to transmit data with the network side device to communicate with the network side device.

[0004] However, since the network side device may not be able to determine the terminal's ability to support transmission functions (such as the ability to support PUCCH repeated transmission, the ability to support frequency hopping between time slots, the ability to support frequency hopping between two adjacent repeated transmissions, etc.), the network side device may not be able to configure the above transmission functions for the terminal. Therefore, the terminal may fail to use common PUCCH resources to transmit data to the network side device.

[0005] Therefore, the communication performance is degraded.

[0025] In the NR system, the terminal can feedback uplink control information (UCI) to the network side device through the PUCCH. The PUCCH resources are configured by the network side device.

[0026] Generally, PUCCH resources are divided into common PUCCH resources and dedicated PUCCH resources.

[0027] The common PUCCH resource is a PUCCH resource used by network-side devices before dedicated PUCCH resources are configured. The common PUCCH resource is a PUCCH resource configured for multiple users, or a common PUCCH resource configured for each serving cell. The PUCCH on the common PUCCH resource can be expressed as a common PUCCH.

[0028] The dedicated PUCCH resource is an exclusive PUCCH resource configured by the network side device for the terminal after the terminal establishes a Radio Resource Control (RRC) connection with the network side device.

[0035] FIG1 shows a block diagram of a wireless communication system applicable to embodiments of the present application. The wireless communication system includes a terminal 11 and a network-side device 12 . The terminal 11 may be a mobile phone, a tablet personal computer, a laptop computer or a notebook computer, a personal digital assistant (PDA), a handheld computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile internet device (MID), an augmented reality (AR) / virtual reality (VR) device, a robot, a wearable device, a vehicle-mounted device (VUE), a pedestrian terminal (PUE), a smart home (a home appliance with wireless communication capabilities, such as a refrigerator, a television, a washing machine, or furniture), a game console, a personal computer (PC), an ATM, or a self-service machine, etc. The wearable device includes: a smart watch, a smart bracelet, a smart headset, smart glasses, smart jewelry (smart bracelets, smart bracelets, smart rings, smart necklaces, smart anklets, smart anklets, etc.), a smart wristband, smart clothing, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiment of the present application. The network side device 12 may include an access network device or a core network device, wherein the access network device 12 may also be referred to as a radio access network device, a radio access network (RAN), a radio access network function, or a radio access network unit. The access network device 12 may include a base station, a WLAN access point, or a WiFi node, etc. The base station may be referred to as a node B, an evolved node B (eNB), an access point, a base transceiver station (BTS), a radio base station, a radio transceiver, a basic service set (BSS), an extended service set (ESS), a home node B, a home evolved node B, a transmitting and receiving point (TRP), or other appropriate terms in the field. As long as the same technical effect is achieved, the base station is not limited to a specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0036] Currently, if the network-side device does not configure dedicated PUCCH resources for the terminal, the terminal can only use common PUCCH resources. However, in some scenarios (such as non-terrestrial networks (NTN)), the reception performance of PUCCH (such as for Msg 4 Hybrid Automatic Repeat reQuest (HARQ)) transmitted using common PUCCH resources cannot meet the requirements, making random access impossible. As a result, all services (such as voice over New Radio (VoNR) based on new air interface technology and low-speed data transmission) channels cannot be transmitted, and then the terminal fails to use common PUCCH resources for data transmission with the network-side device. In related technologies, in order to solve the above problems, the network side device can configure transmission functions for the terminal (such as PUCCH repeated transmission, frequency hopping between time slots, and frequency hopping between two adjacent repeated transmissions) to avoid the situation where all service channels cannot be transmitted. However, since the network side device may not be able to determine the terminal's ability to support transmission functions (such as the ability to support PUCCH repeated transmission, the ability to support frequency hopping between time slots, and the ability to support frequency hopping between two adjacent repeated transmissions), the network side device may not be able to configure the above transmission functions for the terminal. In this way, the terminal may still fail to use common PUCCH resources to transmit data with the network side device.

[0037] However, in an embodiment of the present application, the terminal can transmit random access information on the random access resource, and the terminal's ability to support the transmission function is indicated by at least one of the random access resource and the random access information. Therefore, the network side device can determine the ability to support the transmission function, thereby avoiding the situation where the network side device may not be able to configure the above-mentioned transmission function for the terminal. In this way, the situation where the terminal fails to use common PUCCH resources to perform data transmission with the network side device can be avoided.

[0038] The capability indication method, device, terminal, and medium provided in the embodiments of the present application are described in detail below with reference to some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0039] Figure 2 shows a flow chart of a capability indication method provided by an embodiment of the present application. As shown in Figure 2, the capability indication method provided by an embodiment of the present application may include the following step 101.

[0040] Step 101: A terminal transmits random access information on a random access resource.

[0041] In an embodiment of the present application, the target capability of the above-mentioned terminal is indicated by at least one of the following: random access resources, random access information; the target capability includes at least one of the following: the ability to support PUCCH repeated transmission, the ability to support frequency hopping between time slots, and the ability to support frequency hopping between two adjacent repeated transmissions.

[0042] Optionally, in an embodiment of the present application, when the terminal has not established a radio resource control (RRC) connection with the network side device, or the network side device has not configured a dedicated PUCCH resource for the terminal, the terminal can transmit random access information on the random access resource to indicate the target capability to the network side device.

[0043] Optionally, in an embodiment of the present application, the above-mentioned target capability is the capability of the terminal to use common PUCCH resources for transmission; the target capability may be a set of capabilities or multiple sets of capabilities.

[0044] Optionally, in the embodiment of the present application, the number of target capabilities is multiple groups, and each group of target capabilities is the capabilities corresponding to a type of user equipment (UE) of the terminal.

[0045] Among them, a type of UE can be any one of the following: RedCap UE, non-RedCap UE.

[0046] Each group of target capabilities may specifically be a capability of a type of UE to perform transmission using common PUCCH resources.

[0047] It is understandable that the capabilities of different types of UEs to use common PUCCH resources for PUCCH repeated transmission, to perform frequency hopping between time slots, and to perform frequency hopping between two adjacent repeated transmissions can be reported independently.

[0048] The capability of supporting PUCCH repeated transmission may be: the capability of using common PUCCH resources for PUCCH repeated transmission. The capability of supporting PUCCH repeated transmission may be: supporting the use of common PUCCH resources for PUCCH repeated transmission, or not supporting the use of common PUCCH resources for PUCCH repeated transmission.

[0049] Here, PUCCH retransmission can be PUCCH retransmission for Msg 4 HARQ feedback, or PUCCH retransmission for other situations where the terminal cannot obtain dedicated PUCCH resources. PUCCH retransmission can be inter-slot retransmission, intra-slot retransmission, or cross-slot retransmission.

[0050] Here, the format of the PUCCH transmitted in the PUCCH repeated transmission may be at least one of the following: PUCCH format 1 and PUCCH format 0. Of course, the format of the PUCCH may also be other PUCCH formats, which is not limited in the embodiment of the present application.

[0051] Optionally, in the embodiment of the present application, when the target capability includes the capability to support PUCCH repeated transmission, the target capability includes at least one of the following:

[0052] Support dynamic PUCCH repeated transmission capability;

[0053] Support for semi-static PUCCH repeated transmission capability;

[0054] Support the ability to transmit PUCCH repeatedly within a time slot;

[0055] Supports the ability to transmit PUCCH repeatedly between time slots;

[0056] Supports repeated transmission of PUCCH in a single TRP;

[0057] Supports repeated transmission of PUCCH for multiple TRPs;

[0058] Support for PUCCH retransmission based on PUCCH format;

[0059] Support the ability to transmit PUCCH repeatedly based on PUCCH resources;

[0060] Support for PUCCH repetitive transmission based on available time units;

[0061] Supports the capability of PUCCH repetitive transmission based on physical time units.

[0062] For example, assuming that the target capability is two sets of capabilities, such as capability 1 and capability 2, capability 1 may include the capability of supporting dynamic PUCCH repeated transmission, and capability 2 may include the capability of supporting semi-static PUCCH repeated transmission. It is understood that the capability of supporting dynamic PUCCH repeated transmission and the capability of supporting semi-static PUCCH repeated transmission may be two independent capabilities.

[0063] As another example, the target capability is a set of capabilities, such as capability 1, which may include the capability of supporting dynamic PUCCH repeated transmission and the capability of supporting semi-static PUCCH repeated transmission. It is understood that the capability of supporting dynamic PUCCH repeated transmission and the capability of supporting semi-static PUCCH repeated transmission may also be one capability.

[0064] The above-mentioned ability to support inter-slot frequency hopping may be: the ability to use common PUCCH resources to perform inter-slot frequency hopping. The ability to support inter-slot frequency hopping may be: supporting the use of common PUCCH resources to perform inter-slot frequency hopping, or not supporting the use of common PUCCH resources to perform inter-slot frequency hopping.

[0065] The capability of supporting frequency hopping between two adjacent repetition transmissions (inter-repetition frequency hopping) may be: the capability of using common PUCCH resources to perform frequency hopping between two adjacent repetition transmissions. The capability of supporting frequency hopping between two adjacent repetition transmissions may be: supporting frequency hopping between two adjacent repetition transmissions using common PUCCH resources, or not supporting frequency hopping between two adjacent repetition transmissions using common PUCCH resources.

[0066] The above-mentioned time unit may specifically be any one of the following: system frame, time slot, mini-time slot, etc.

[0067] Optionally, in an embodiment of the present application, the random access resource may be a common PUCCH resource.

[0068] Optionally, in this embodiment of the present application, the random access resource includes at least one of the following:

[0069] PRACH's resources;

[0071] Msg A's resources;

[0072] PUSCH resources in Msg 3.

[0073] The PRACH resource includes at least one of the following:

[0080] Exemplarily, assuming that the target capability includes the capability to support PUCCH repeated transmission, and the PRACH resources include the time domain resources of the PRACH, if the terminal supports the use of common PUCCH resources for PUCCH repeated transmission, the terminal can transmit random access information on the time domain resources 1 of the PRACH to indicate to the network side device that the terminal supports the use of common PUCCH resources for PUCCH repeated transmission; or, if the terminal does not support the use of common PUCCH resources for PUCCH repeated transmission, the terminal can transmit random access information on the time domain resources 2 of the PRACH to indicate to the network side device that the terminal does not support the use of common PUCCH resources for PUCCH repeated transmission.

[0081] It should be noted that for the description of indicating the target capability through other resources in the PRACH resources (i.e., the frequency domain resources of the PRACH, and / or the sequence of the PRACH, and / or the scrambling sequence of the PRACH sequence, and / or the format of the PRACH), reference can be made to the specific description of indicating the target capability through the time domain resources of the PRACH, and the embodiments of the present application will not be repeated here.

[0082] Here, the first PRACH resource indicates whether the terminal performs PRACH retransmission.

[0083] Exemplarily, assuming that the target capability includes the capability of supporting PUCCH repeated transmission, if the terminal performs PRACH repeated transmission, it can be considered that the terminal supports using common PUCCH resources for PUCCH repeated transmission.

[0084] It should be noted that for the description of other capabilities indicated by PRACH resources (i.e., the ability to support frequency hopping between time slots, and / or the ability to support frequency hopping between two adjacent repeated transmissions), please refer to the specific description of the ability to support PUCCH repeated transmission through PRACH resource indication, and the embodiments of the present application will not be repeated here.

[0085] The PUSCH resource in the above Msg A includes at least one of the following:

[0086] Msg A PUSCH time domain resources;

[0087] Msg A PUSCH frequency domain resources;

[0088] Msg A PUSCH demodulation reference signal (DMRS) resources;

[0089] The group where Msg A PUSCH belongs;

[0090] First Msg A PUSCH resource.

[0091] It can be understood that the target capability can be implicitly indicated by the resources of Msg A PUSCH.

[0092] Exemplarily, assuming that the target capability includes the capability to support PUCCH repeated transmission, and the PUSCH resources in Msg A include the group to which Msg A PUSCH belongs, then in the two-step random access (2-step Random Access, 2-stepRACH) process, if the terminal supports the use of common PUCCH resources for PUCCH repeated transmission, the terminal can transmit random access information on Msg A PUSCH group A to indicate to the network side device that the terminal supports the use of common PUCCH resources for PUCCH repeated transmission; or, if the terminal does not support the use of common PUCCH resources for PUCCH repeated transmission, the terminal can transmit random access information on Msg A PUSCH group B to indicate to the network side device that the terminal does not support the use of common PUCCH resources for PUCCH repeated transmission.

[0093] It should be noted that, for the description of indicating the target capability through other resources in the PUSCH resources in Msg A (i.e., the frequency domain resources of Msg A PUSCH, and / or the DMRS resources of Msg A PUSCH, and / or the group to which Msg A PUSCH belongs), please refer to the specific description of indicating the target capability through the time domain resources of Msg A PUSCH, and the embodiments of the present application will not be repeated here.

[0094] Here, the first Msg A PUSCH resource indicates whether the terminal performs repeated Msg A PUSCH transmission.

[0095] It should be noted that, for the description of other capabilities indicated by the PUSCH resources in Msg A (i.e., the ability to support frequency hopping between time slots, and / or the ability to support frequency hopping between two adjacent repeated transmissions), please refer to the specific description of the ability to support PUCCH repeated transmission through the PUSCH resource indication in Msg A, and the embodiments of the present application will not be repeated here.

[0096] The resources of Msg A include at least one of the following:

[0097] Msg A's time domain resources;

[0098] Frequency domain resources of Msg A;

[0099] Msg A's DMRS resources.

[0100] Exemplarily, assuming that the target capability includes the capability to support PUCCH repeated transmission, and the resources of Msg A include the time domain resources of Msg A, then in the 2-step RACH process, if the terminal supports the use of common PUCCH resources for PUCCH repeated transmission, the terminal can transmit random access information on the time domain resources 1 of Msg A to indicate to the network side device that the terminal supports the use of common PUCCH resources for PUCCH repeated transmission; or, if the terminal does not support the use of common PUCCH resources for PUCCH repeated transmission, the terminal can transmit random access information on the time domain resources 2 of Msg A to indicate to the network side device that the terminal does not support the use of common PUCCH resources for PUCCH repeated transmission.

[0101] It should be noted that, for the description of other capabilities indicated by the resources of Msg A (i.e., the ability to support frequency hopping between time slots, and / or the ability to support frequency hopping between two adjacent repeated transmissions), please refer to the specific description of the ability to support PUCCH repeated transmission through the resources of Msg A, and the embodiments of the present application will not be repeated here.

[0102] The PUSCH resource in the above Msg 3 includes at least one of the following:

[0103] Msg 3 PUSCH time domain resources;

[0104] Msg 3 PUSCH frequency domain resources;

[0105] Msg 3 PUSCH DMRS resources;

[0106] Msg 3 PUSCH payload size;

[0107] First Msg 3 PUSCH resource.

[0108] Exemplarily, assuming that the target capability includes the capability to support PUCCH repeated transmission, and the PUSCH resources in Msg 3 include the time domain resources of Msg 3 PUSCH, then in the four-step random access (4-step Random Access, 4-stepRACH) process, if the terminal supports the use of common PUCCH resources for PUCCH repeated transmission, the terminal can transmit random access information on the time domain resources 1 of Msg 3 PUSCH to indicate to the network side device that the terminal supports the use of common PUCCH resources for PUCCH repeated transmission; or, if the terminal does not support the use of common PUCCH resources for PUCCH repeated transmission, the terminal can transmit random access information on the time domain resources 2 of Msg 3 PUSCH to indicate to the network side device that the terminal does not support the use of common PUCCH resources for PUCCH repeated transmission.

[0109] Here, the first Msg 3 PUSCH resource indicates whether the terminal supports repeated transmission of Msg 3 PUSCH.

[0110] It should be noted that, for the description of other capabilities indicated by the PUSCH resources in Msg 3 (i.e., the ability to support frequency hopping between time slots, and / or the ability to support frequency hopping between two adjacent repeated transmissions), please refer to the specific description of the ability to support PUCCH repeated transmission through the PUSCH resource indication in Msg 3, and the embodiments of the present application will not be repeated here.

[0111] Optionally, in this embodiment of the present application, the random access information includes at least one of the following:

[0112] Information carried by the PUSCH in Msg A;

[0113] Information carried by the PUSCH in Msg 3.

[0114] It will be appreciated that the target capability may be explicitly indicated by the information carried by the PUSCH in Msg A, and / or may be explicitly indicated by the information carried by the PUSCH in Msg 3.

[0115] In the capability indication method provided in the embodiment of the present application, a terminal can transmit random access information on a random access resource, and the target capability of the terminal is indicated by at least one of the random access resource and the random access information, so that the network-side device can determine the target capability; wherein the target capability includes at least one of the capability to support PUCCH repeated transmission, the capability to support frequency hopping between time slots, and the capability to support frequency hopping between two adjacent repeated transmissions. Since the terminal can indicate the target capability of the terminal to the network-side device through at least one of the random access resource and the random access information, the situation in which the network-side device is unable to configure the transmission function (i.e., PUCCH repeated transmission, frequency hopping between time slots, and frequency hopping between two adjacent repeated transmissions) for the terminal can be avoided, thereby avoiding the situation in which the terminal fails to perform data transmission with the network-side device using common PUCCH resources, thereby improving communication performance.

[0116] Furthermore, since the terminal can indicate the target capability of the terminal to the network side device through at least one of the random access resources and the random access information, the reliability of PUCCH transmission using common PUCCH resources can be improved, thereby ensuring the success rate of HARQ feedback before the RRC connection is established.

[0117] Of course, when the target capability is multiple groups of capabilities, each group of capabilities may include different capabilities, and each group of capabilities may be indicated by a combination of different PRACH resources, and / or PUSCH resources in Msg A, and / or resources of Msg A, and / or PUSCH resources in Msg 3, as illustrated below.

[0118] Optionally, in an embodiment of the present application, the number of the above-mentioned target capabilities is multiple groups, the number of the above-mentioned random access resources is multiple, and the number of the above-mentioned random access information is multiple; wherein each group of target capabilities is indicated by at least one of the following: at least one random access resource, at least one random access information.

[0119] For example, assuming that the target capability includes the capability to support repeated transmission of PUCCH within a time slot and the capability to support repeated transmission of PUCCH between time slots, and the random access resource includes a sequence of PRACH, four preamble groups can be defined on each PRACH opportunity (occasion), as shown in Table 1. If the terminal only supports repeated transmission of PUCCH within a time slot and does not support repeated transmission of PUCCH between time slots, the terminal can transmit random access information on the PRACH in group A to indicate to the network side device that the terminal only supports repeated transmission of PUCCH within a time slot and does not support repeated transmission of PUCCH between time slots; if the terminal only supports repeated transmission of PUCCH between time slots and does not support repeated transmission of PUCCH within a time slot, the terminal can Random access information is transmitted on the PRACH in group B to indicate to the network side device that the terminal only supports PUCCH repetition transmission between time slots, and does not support PUCCH repetition transmission within a time slot; if the terminal supports PUCCH repetition transmission between time slots and PUCCH repetition transmission within a time slot, the terminal can transmit random access information on the PRACH in group C to indicate to the network side device that the terminal supports PUCCH repetition transmission between time slots and PUCCH repetition transmission within a time slot; if the terminal does not support PUCCH repetition transmission between time slots and PUCCH repetition transmission within a time slot, the terminal can transmit random access information on the PRACH in group D to indicate to the network side device that the terminal does not support PUCCH repetition transmission between time slots and PUCCH repetition transmission within a time slot.

[0120] Table 1

[0121] Of course, the terminal can also indicate to the network side device the ability of the terminal to support PUCCH repeated transmission, so that the network side device can determine the terminal's ability to support frequency hopping between time slots and / or the ability to support frequency hopping between two adjacent repeated transmissions based on the ability to support PUCCH repeated transmission. An example will be given below.

[0122] Optionally, in an embodiment of the present application, when the target capability is the capability to support PUCCH repeated transmission, the first capability of the terminal is represented by the target capability; wherein the first capability includes at least one of the following: the capability to support frequency hopping between time slots, and the capability to support frequency hopping between two adjacent repeated transmissions. When the capability to support PUCCH repeated transmission is supporting PUCCH repeated transmission, the network-side device may determine whether the terminal supports frequency hopping between time slots and / or supports frequency hopping between two adjacent repeated transmissions.

[0123] In a case where the capability of supporting PUCCH repeated transmission is not to support PUCCH repeated transmission, the network side device may determine that the terminal does not support frequency hopping between time slots and / or does not support frequency hopping between two adjacent repeated transmissions.

[0124] It can be seen that since the terminal can only report the capability representation of supporting PUCCH repeated transmission to the network side device, so that the network side device can determine at least one of the terminal's ability to support frequency hopping between time slots and the ability to support frequency hopping between two adjacent repeated transmissions, it is possible to save resources for reporting the terminal's capabilities.

[0125] Of course, the terminal's ability to support frequency hopping between time slots and the ability to support frequency hopping between two adjacent repeated transmissions may also be determined as mandatory, which will be explained with examples below.

[0126] Optionally, in an embodiment of the present application, when the target capability is the capability to support PUCCH repeated transmission, the terminal's capability to support frequency hopping between time slots is to support frequency hopping between time slots, and the terminal's capability to support frequency hopping between two adjacent repeated transmissions is to support frequency hopping between two adjacent repeated transmissions.

[0127] It can be understood that the network-side device may assume by default that the terminal supports frequency hopping between time slots and / or supports frequency hopping between two adjacent repeated transmissions.

[0128] As can be seen, since it can be assumed that the terminal supports frequency hopping between time slots and / or supports frequency hopping between two adjacent repeated transmissions, the terminal does not need to report, thereby saving resources for reporting the terminal's capabilities.
