[0044] The embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be understood as limiting the present disclosure.

[0045] Before explaining the embodiments of the present disclosure in detail, common technical terms are first introduced for ease of understanding:

[0046] 1. SDT (Small Data Transmission)

[0047] Depending on the resources configured on the network side, when the UE is in the IDLE / INACTIVE state, it can send data directly to the network side device in the following ways:

[0048] The first is Msg3 of the 4-step random access procedure for initial access (also known as 4-step RACH (Random access channel) SDT).

[0049] The second type is MsgA of the 2-step random access procedure for initial access (or 2-step RACHSDT).

[0050] The third type is dedicated uplink PUSCH (Physical Uplink Shared Channel) resources (i.e., CG (Configure Grant) resources or PUR (Preallocated Uplink Resource)) configured by network-side devices (or CG SDT).

[0051] As an example, taking the network side device as a 5G base station (gNB) in the 5G network architecture (next generation system), the SDT process can be as follows: Figure 1 As shown. That is, the SDT process can include the following two stages:

[0052] Phase 1: Initial Data Transmission Phase (Initial Phase): This phase starts from triggering the SDT initial data transmission to receiving confirmation information for the initial data sent by the network-side device.

[0053] The above confirmation information may vary in different SDT processes:

[0054] 1) 4-step RACH SDT: Confirms that the contention resolution flag of Msg4 has been successfully received.

[0055] 2) 2-step RACH SDT: Confirms that the contention resolution flag of MsgB has been successfully received.

[0056] 3) CG SDT: The confirmation information is an indication of successful data reception sent by the network side device (for example, the confirmation information may be ACK (Acknowledgement) information indicated by the physical layer DCI (Downlink Control Information)).

[0057] Phase 2: Subsequent Data Transmission Phase. This phase is from receiving the confirmation message for the initial data sent by the network device to receiving the connection release message sent by the network device. During this phase, the UE can send and receive uplink and downlink data.

[0058] As an example, taking the network side device as gNB, the CG-SDT process can be as follows: Figure 2As shown. For the CG-SDT resource configured by the network side device, the UE uses the CG resource (such as Figure 2 After sending data to the resource in the CG (e.g., resource -1), the feedback timer will be started to monitor the feedback information of the network side device. If the UE does not receive the successful reception confirmation sent by the network side device during the operation of the feedback timer (e.g., feedbackTimer), the UE will not receive the successful reception confirmation sent by the network side device in the subsequent CG resources (e.g., resource -2). Figure 2 Resources-4) in the data retransmission.

[0059] In the related art, for the CG-SDT process, the network side device can configure multiple periodic CG resources, and the multiple CG resources can correspond to different HARQ (Hybrid Automatic Repeat Request) processes. For a specific SDT process, whether the above-mentioned multiple CG resources can be used at the same time, and in which data sending phase of the SDT process (i.e., the initial data sending phase or the subsequent data sending phase) the above-mentioned multiple CG resources are used are problems that need to be solved. At the same time, for the CG-SDT process, how to enable the network side device to continuously dynamically schedule the data transmission of the UE (i.e., the PDCCH (Physical Downlink Control Channel) corresponding to the UE identifier), thereby improving the data transmission rate of the UE, is also a problem that needs to be solved.

[0060] To address the above problems, the present disclosure provides a data transmission method, apparatus, and communication device.

[0061] Figure 3 A flowchart of a data transmission method provided in an embodiment of the present disclosure is provided. The data transmission method can be executed by a UE.

[0062] A UE can be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connectivity, or other processing device connected to a wireless modem. The name of a UE may vary in different systems. A wireless UE can communicate with one or more core networks (CNs) via a RAN (Radio Access Network). A wireless UE can be a mobile terminal device, such as a mobile phone (or "cellular" phone) or a computer with a mobile terminal device. For example, a portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile device can exchange voice and / or data with a radio access network.

[0063] For example, a UE may be a PCS (Personal Communication Service) phone, a cordless phone, a SIP (Session Initiated Protocol) phone, a WLL (Wireless Local Loop) station, a PDA (Personal Digital Assistant), or other devices. A wireless UE may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, or a user device, but is not limited in the embodiments of the present disclosure.

[0064] like Figure 3 As shown, the data transmission method may include the following steps:

[0065] Step 101: Determine the current data sending phase.

[0066] In the embodiment of the present disclosure, the current data sending phase may include an initial data sending phase or a subsequent data sending phase.

[0067] Step 102: Use the CG SDT resources in the CG SDT process according to the current data sending phase.

[0068] In the embodiment of the present disclosure, the CG SDT resources are used for data transmission in the SDT process, and the CG SDT resources can be configured by the network side device, that is, the UE can receive the CG SDT resources configured by the network side device.

[0069] The network-side equipment is exemplified by a base station. A base station can include multiple cells that provide services to UEs. Depending on the specific application scenario, each cell can contain multiple TRPs (Transmission Reception Points or Transmit Receive Points). Each TRP can include one or more antenna panels, or can be a device in the access network that communicates with wireless terminal devices over the air interface through one or more sectors, or other names. For example, the base station involved in the embodiments of the present disclosure can be a BTS (Base Transceiver Station) in GSM (Global System for Mobile communications) or CDMA (Code Division Multiple Access), or a base station (NodeB) in WCDMA (Wide-band Code Division Multiple Access), or an evolved Node B (eNB or e-NodeB for short) in an LTE (long term evolution) system, a 5G base station (gNB for short) in a 5G network architecture (next generation system), or a HeNB (Home evolved Node B), a relay node, a femto, a pico base station, etc., which is not limited in the embodiments of the present disclosure.

[0070] In the disclosed embodiments, the UE may use CGSDT resources in the CG SDT process according to the current data transmission phase. Thus, the UE may use appropriate CG SDT resources for data transmission according to the current data transmission phase, thereby improving the UE's data transmission rate and enabling the UE to send more data in the SDT process.

[0071] The data transmission method of the disclosed embodiment determines the current data transmission phase through the UE and uses the CG SDT resources in the CG SDT process according to the current data transmission phase. As a result, the UE can use appropriate CG SDT resources for data transmission according to the current data transmission phase, thereby improving the UE's data transmission rate, thereby allowing the UE to send more data during the SDT process.

[0072] The present disclosure provides another data transmission method. Figure 4This is a flow chart of another data transmission method provided in an embodiment of the present disclosure. This data transmission method can be executed by a UE. This data transmission method can be executed alone, or in combination with any embodiment of the present disclosure or a possible implementation thereof, or in combination with any technical solution in related technologies.

[0073] like Figure 4 As shown, the data transmission method may include the following steps:

[0074] Step 201: Determine whether the current data sending phase is the initial data sending phase.

[0075] In an embodiment of the present disclosure, the UE may determine a current data transmission phase, and in a case where the current data transmission phase is an initial data transmission phase, the execution of subsequent steps may be triggered.

[0076] Step 202: After the UE uses the first CG SDT resource to send data, in response to not receiving feedback information from the network-side device, it no longer uses other CG SDT resources to send data.

[0077] In the embodiment of the present disclosure, the first CG SDT resource and the other CG SDT resources may be CG SDT resources configured by the network side device.

[0078] As a possible implementation method, the network side device can release a Release message to the UE via RRC (Radio Resource Control) to configure CG SDT resources. The UE can then receive the RRC Release message sent by the network side device and determine the CG SDT resources configured by the network side device based on the RRC Release message.

[0079] In the embodiment of the present disclosure, the first CG SDT resource is the CGSDT resource used by the UE when triggering CG SDT data transmission.

[0080] In the embodiments of the present disclosure, during the initial data transmission phase, after the UE uses the first CG SDT resource to send data, if no feedback information is received from the network-side device, the UE will no longer use other CG SDT resources to send data. That is, during the initial data transmission phase, after the UE triggers data transmission and before receiving feedback information from the network-side device, the UE will no longer use other CG SDT resources to send data.

[0081] As an example, the first CG SDT resource is a CG SDT resource corresponding to one of the CG SDT resources corresponding to multiple HARQ processes in the CG SDT resources. For example, the CG SDT resources configured by the network side device for the UE correspond to multiple HARQ processes. During the initial data transmission phase, after the UE selects one of the HARQ processes for data transmission, the UE no longer uses other HARQ processes to send data during the initial data transmission phase.

[0082] As an example, Figure 2 As shown, after the UE triggers CG SDT data transmission (the data transmission can be the initial transmission of resource-1, or the data transmission can also be a retransmission of resource-4), the UE can start the feedback timer to monitor the feedback information of the network-side device. Before the UE receives the feedback information of the network-side device, the UE cannot use other CG SDT resources for data transmission, for example, the UE cannot use resource-2 or resource-3 for data transmission. In this way, it can be avoided that if the first data transmission is unsuccessful, the subsequent data transmission does not carry the identification of the verification UE, which causes the network-side device to fail to receive subsequent data.

[0083] The data transmission method of the disclosed embodiment determines the current data transmission phase through the UE and uses the CG SDT resources in the CG SDT process according to the current data transmission phase. As a result, the UE can use appropriate CG SDT resources for data transmission according to the current data transmission phase, thereby improving the UE's data transmission rate, thereby allowing the UE to send more data during the SDT process.

[0084] It should be noted that the above-mentioned possible implementation methods can be executed separately or in combination, and the embodiments of the present disclosure are not limited to this.

[0085] The present disclosure provides another data transmission method. Figure 5 This is a flow chart of another data transmission method provided in an embodiment of the present disclosure. This data transmission method can be executed by a UE. This data transmission method can be executed alone, or in combination with any embodiment of the present disclosure or a possible implementation thereof, or in combination with any technical solution in related technologies.

[0086] like Figure 5 As shown, the data transmission method may include the following steps:

[0087] Step 301: Determine whether the current data sending phase is the initial data sending phase.

[0088] Step 302: After the UE uses the first CG SDT resource to send data, in response to not receiving feedback information from the network-side device, it no longer uses other CG SDT resources to send data.

[0089] In the embodiment of the present disclosure, steps 301 to 302 may be implemented in any manner in the embodiments of the present disclosure, and the embodiment of the present disclosure does not limit this and will not be described in detail.

[0090] Step 303: until it is determined that the retransmission condition is met, the data is retransmitted using the retransmission CG SDT resource.

[0091] As an example, after using the first CG SDT resource to send data, the UE can start a feedback timer (e.g., feedbackTimer) to monitor feedback information from the network-side device. If the UE does not receive feedback information (e.g., successful reception confirmation information) sent by the network-side device during the running of the feedback timer, the UE can determine that the retransmission condition is met and can use the retransmission CG SDT resource to retransmit the data.

[0092] For example, the first CG SDT resource can be Figure 2 The resource in -1, the retransmission resource can be Figure 2 For resource-4 in the CG SDT, after the UE uses resource-1 to send data, it can start the feedback timer to monitor the feedback information of the network side device. If the UE does not receive any feedback information from the network side device (such as successful reception confirmation information) during the operation of the feedback timer, the UE can retransmit the data in the subsequent CG SDT resource (i.e., resource-4).

[0093] The data transmission method of the disclosed embodiment determines the current data transmission phase through the UE and uses the CG SDT resources in the CG SDT process according to the current data transmission phase. As a result, the UE can use appropriate CG SDT resources for data transmission according to the current data transmission phase, thereby improving the UE's data transmission rate, thereby allowing the UE to send more data during the SDT process.

[0094] It should be noted that the above-mentioned possible implementation methods can be executed separately or in combination, and the embodiments of the present disclosure are not limited to this.

[0095] The present disclosure provides another data transmission method. Figure 6This is a flow chart of another data transmission method provided in an embodiment of the present disclosure. This data transmission method can be executed by a UE. This data transmission method can be executed alone, or in combination with any embodiment of the present disclosure or a possible implementation thereof, or in combination with any technical solution in related technologies.

[0096] like Figure 6 As shown, the data transmission method may include the following steps:

[0097] Step 401: Determine whether the current data sending phase is a subsequent data sending phase.

[0098] In an embodiment of the present disclosure, the UE may determine a current data transmission phase, and in a case where the current data transmission phase is a subsequent data transmission phase, the execution of subsequent steps may be triggered.

[0099] Step 402: Use multiple CG SDT resources for transmission.

[0100] In an embodiment of the present disclosure, in the subsequent data sending stage, the UE may use multiple CG SDT resources for transmission, for example, the UE may use multiple consecutive CG SDT resources for transmission, or the UE may use multiple CG SDT resources continuously for transmission.

[0101] As an example, the CG SDT resources configured by the network side device for the UE correspond to multiple HARQ processes. In the subsequent data sending phase, the UE can use multiple HARQ processes to send data.

[0102] In a possible implementation of the embodiment of the present disclosure, the above-mentioned multiple CG SDT resources may correspond to the same beam, or the above-mentioned multiple consecutive CG SDT resources may correspond to the same beam.

[0103] In another possible implementation of the embodiment of the present disclosure, the above-mentioned multiple CG SDT resources may belong to the same CG SDT resource group, or the above-mentioned multiple consecutive CG SDT resources may belong to the same CG SDT resource group.

[0104] As an example, the above-mentioned multiple CG SDT resources or the above-mentioned multiple continuous CG SDT resources can be associated with the same downlink signal. For example, the network side device configures multiple sets of CG SDT resources for the UE, and the multiple sets of CG SDT resources correspond to different downlink signals (such as SSB (Synchronous Signal Block)); or, there are multiple CG SDT resources in one CG SDT resource sending cycle (for example, multiple CG SDT resources correspond to CG SDT resource-1, CG SDT resource-2, CG SDT resource-3, and CG SDT resource-4), and these multiple CG resources correspond to different downlink signals (for example, CGSDT resource-1 corresponds to SSB-1, CG SDT resource-2 corresponds to SSB-2, CG SDT resource-3 corresponds to SSB-3, and CG SDT resource-4 corresponds to SSB-4). Then, the downlink signals associated with the CG SDT resources used by the UE in multiple resource sending cycles in the "subsequent data sending phase" are the same.

[0105] In another possible implementation of the embodiment of the present disclosure, the above-mentioned multiple CG SDT resources may correspond to the same beam as the CG SDT resources in the initial data sending phase, or the above-mentioned multiple consecutive CG SDT resources may correspond to the same beam as the CG SDT resources in the initial data sending phase.

[0106] In another possible implementation of the embodiment of the present disclosure, the above-mentioned multiple CG SDT resources may belong to the same CG SDT resource group as the CG SDT resources in the initial data sending phase, or the above-mentioned multiple consecutive CG SDT resources may belong to the same CG SDT resource group as the CG SDT resources in the initial data sending phase.

[0107] As an example, the downlink signals associated with the above-mentioned multiple CG SDT resources or the above-mentioned consecutive multiple CG SDT resources may be the same as the downlink signals associated with the CG SDT resources used by the UE in the "initial data sending phase". For example, the network-side device configures multiple sets of CG SDT resources for the UE, and the multiple sets of CG SDT resources correspond to different downlink signals (such as SSB); or, there are multiple CG SDT resources in one CG SDT resource sending cycle (for example, multiple CG SDT resources correspond to CG SDT resource-1, CG SDT resource-2, CG SDT resource-3, and CG SDT resource-4), and these multiple CG resources correspond to different downlink signals (for example, CG SDT resource-1 corresponds to SSB-1, CG SDT resource-2 corresponds to SSB-2, CG SDT resource-3 corresponds to SSB-3, and CG SDT resource-4 corresponds to SSB-4). In the "initial data sending phase", the UE uses the CG SDT resource-1 associated with SSB-1 to send data, so the UE also uses the CG SDT resource associated with SSB-1 to send data in the "subsequent data sending phase".

[0108] The data transmission method of the disclosed embodiment determines the current data transmission phase through the UE and uses the CG SDT resources in the CG SDT process according to the current data transmission phase. As a result, the UE can use appropriate CG SDT resources for data transmission according to the current data transmission phase, thereby improving the UE's data transmission rate, thereby allowing the UE to send more data during the SDT process.

[0109] It should be noted that the above-mentioned possible implementation methods can be executed separately or in combination, and the embodiments of the present disclosure are not limited to this.

[0110] The present disclosure provides another data transmission method. Figure 7 This is a flow chart of another data transmission method provided in an embodiment of the present disclosure. This data transmission method can be executed by a UE. This data transmission method can be executed alone, or in combination with any embodiment of the present disclosure or a possible implementation thereof, or in combination with any technical solution in related technologies.

[0111] like Figure 7 As shown, the data transmission method may include the following steps:

[0112] Step 501: Determine the current data sending phase.

[0113] Step 502: Use the CG SDT resources in the CG SDT process according to the current data sending phase.

[0114] In the embodiment of the present disclosure, steps 501 to 502 can be implemented in any manner in the embodiments of the present disclosure, and the embodiment of the present disclosure does not limit this and will not be described in detail.

[0115] Step 503: Use specific PDCCH resource configuration to monitor control information of the network side device.

[0116] In the embodiment of the present disclosure, the above-mentioned specific PDCCH resources may be configured by a network-side device.

[0117] As a possible implementation manner, the network-side device may configure the above-mentioned specific PDCCH resources through an RRC Release message.

[0118] As another possible implementation manner, the network-side device may configure the above-mentioned specific PDCCH resources through a system message.

[0119] In the embodiment of the present disclosure, whether in the initial data transmission phase or the subsequent data transmission phase, the UE can use a specific PDCCH resource configuration to monitor the control information of the network side device.

[0120] As an example, in the current data sending phase (the current data sending phase may be the initial data sending phase, or it may be the subsequent data sending phase), the UE may use the above-mentioned specific PDCCH resource configuration to monitor the control information of the network side device, and the control information is used to schedule the reception and transmission of subsequent data.

[0121] The data transmission method of the disclosed embodiment determines the current data transmission phase through the UE and uses the CG SDT resources in the CG SDT process according to the current data transmission phase. As a result, the UE can use appropriate CG SDT resources for data transmission according to the current data transmission phase, thereby improving the UE's data transmission rate, thereby allowing the UE to send more data during the SDT process.

[0122] It should be noted that the above-mentioned possible implementation methods can be executed separately or in combination, and the embodiments of the present disclosure are not limited to this.

[0123] In any embodiment of the present disclosure, the specific PDCCH resource includes at least one of the following aspects:

[0124] First, specific resource identification;

[0125] For example, the network side device can configure the C-RNTI (Cell Radio Network Temporary Identifier) ​​for the specific PDCCH resource through the RRC Release message. The C-RNTI is a specific resource identifier or PDCCH resource identifier. The UE can use the PDCCH resource corresponding to the C-RNTI identifier as a specific PDCCH resource, so that the specific PDCCH resource can be used to monitor the control information of the network side device.

[0126] The second aspect is the specific time domain resource configuration;

[0127] For example, the specific time domain resource configuration may be a specific search space configuration.

[0128] The third aspect is the specific frequency domain resource configuration;

[0129] For example, the specific frequency domain resource configuration may be a specific CORESET (Control Resource Set) configuration.

[0130] Fourthly, the PDCCH resource is the same as the PDCCH resource corresponding to the feedback information received from the network side device in the initial data transmission phase;

[0131] That is, the specific PDCCH resource may be the same as the PDCCH resource corresponding to the feedback information received by the UE from the network-side device in the "initial data transmission phase".

[0132] Fifthly, the downlink signal associated with the specific PDCCH resource is the same as the downlink signal associated with the CG SDT resource used by the UE during the initial data transmission phase.

[0133] For example, the spatial relationship signal corresponding to a specific PDCCH resource is the same as the downlink signal associated with the CG SDT resource used by the UE in the "initial data transmission phase." The spatial relationship signal may be, for example, a signal corresponding to a TCI (Transmission Configuration Indication) state.

[0134] In any embodiment of the present disclosure, the identifier of the "downlink signal" includes at least one of the following: an SSB identifier; a CSI-RS (Channel State Information-Reference Signal) identifier.

[0135] The present disclosure provides another data transmission method. Figure 8 This is a flow chart of another data transmission method provided in an embodiment of the present disclosure. This data transmission method can be executed by a UE. This data transmission method can be executed alone, or in combination with any embodiment of the present disclosure or a possible implementation thereof, or in combination with any technical solution in related technologies.

[0136] like Figure 8 As shown, the data transmission method may include the following steps:

[0137] Step 601: Determine the current data sending phase.

[0138] Step 602: Use the CG SDT resources in the CG SDT process according to the current data sending phase.

[0139] In the embodiment of the present disclosure, steps 601 to 602 can be implemented in any of the ways in the embodiments of the present disclosure, and the embodiment of the present disclosure does not limit this and will not be described in detail.

[0140] Step 603: Determine whether the current data sending phase is a subsequent data sending phase.

[0141] Step 604: Use specific PDCCH resource configuration to monitor control information of the network side device.

[0142] It should be noted that the explanation of the specific PDCCH resources in the above embodiments is also applicable to this embodiment and will not be repeated here.

[0143] In the embodiment of the present disclosure, the UE may use a specific PDCCH resource configuration to monitor control information of a network-side device in a subsequent data transmission phase.

[0144] As an example, when the current data transmission phase is a subsequent data transmission phase, the UE may use the above-mentioned specific PDCCH resource configuration to monitor control information on the network side, where the control information is used to schedule reception and transmission of subsequent data.

[0145] The data transmission method of the disclosed embodiment determines the current data transmission phase through the UE and uses the CG SDT resources in the CG SDT process according to the current data transmission phase. As a result, the UE can use appropriate CG SDT resources for data transmission according to the current data transmission phase, thereby improving the UE's data transmission rate, thereby allowing the UE to send more data during the SDT process.

[0146] It should be noted that the above-mentioned possible implementation methods can be executed separately or in combination, and the embodiments of the present disclosure are not limited to this.

[0147] In one embodiment of the present disclosure, the scheduling mode and dynamic scheduling mode of the CG SDT resources of the CGSDT can be controlled through protocol agreement or network side device configuration, that is, the UE can distinguish different data sending stages according to the configuration of the network side device or protocol agreement, and use the CG SDT resources and / or dynamic scheduling resources of the CG SDT process.

[0148] In one embodiment of the present disclosure, the network-side device may configure for the UE specific PDCCH resources used by the UE in the "subsequent data transmission phase" of the CG SDT process.

[0149] In one embodiment of the present disclosure, the network side device may configure CG SDT resources for the UE. For example, the network side device may configure CG SDT resources for the UE through an RRC Release message, and the CG SDT resources are used for data transmission during the SDT process.

[0150] In one embodiment of the present disclosure, the UE may trigger the SDT process and select the CG SDT process to send data.

[0151] In one embodiment of the present disclosure, based on the configuration of the network-side device or the protocol agreement, the UE may send and receive data according to any one of the following rules:

[0152] Rule 1: In the "initial data transmission phase", after the UE triggers data transmission and before receiving feedback information from the network-side device, the UE cannot use other CG SDT resources to send data.

[0153] As an example, the CG SDT resources configured by the network side device for the UE correspond to multiple HARQ processes. In the initial data sending phase, after the UE selects one of the HARQ processes for data transmission, the UE no longer uses other HARQ processes to send data in the initial data sending phase.

[0154] like Figure 2 As shown, the UE triggers CG SDT data transmission, which can be the initial transmission of resource-1 or the retransmission of resource-4. The UE then starts the feedback timer to monitor the feedback information from the network-side device. Before the UE receives the feedback information from the network-side device, the UE cannot use other CG SDT resources. For example, the UE cannot use resource-2 or resource-3 for data transmission. This can avoid the situation where if the first data transmission is unsuccessful, the subsequent data transmission does not carry the verification UE identifier, resulting in the failure of subsequent data reception.

[0155] Rule 2: In the "subsequent data transmission phase", the UE can use multiple CG SDT resources continuously, or the UE can use multiple CG SDT resources continuously.

[0156] As an example, the CG SDT resources configured by the network side device for the UE correspond to multiple HARQ processes. In the subsequent data sending phase, the UE can use multiple HARQ processes to send data.

[0157] Rule 3: In the "subsequent data transmission phase", the UE uses a specific PDCCH resource configuration to monitor the control information of the network-side device.

[0158] For example, the network side device configures specific PDCCH resources for the UE in advance through the RRC Release message or system information. When the UE enters the "subsequent data sending phase", the UE can use the specific PDCCH resource configuration to monitor the control information of the network side device, and the control information can be used to schedule the reception and transmission of subsequent data.

[0159] As a result, the UE can use CG SDT resources and / or dynamically scheduled resources (such as specific PDCCH resources) to continuously transmit uplink and / or downlink data in the appropriate "data sending phase" during the CG SDT process, thereby supporting the UE to send more data during the SDT process.

[0160] The present disclosure provides another data transmission method. Figure 9 This is a flow chart of another data transmission method provided by an embodiment of the present disclosure. This data transmission method can be executed by a network-side device. This data transmission method can be executed alone, in combination with any embodiment of the present disclosure or any possible implementation thereof, or in combination with any technical solution in related technologies.

[0161] like Figure 9 As shown, the data transmission method may include the following steps:

[0162] Step 701: Send the configured CG SDT resources to the UE; wherein the UE uses the CG SDT resources in the CGSDT process according to the current data sending phase.

[0163] Optionally, in a possible implementation manner of an embodiment of the present disclosure, the network side device may send a first RRC Release message to the UE, wherein the CG SDT resources are configured through the first RRC Release message.

[0166] Optionally, in a possible implementation manner of the embodiment of the present disclosure, the network side device may send a system message to the UE, wherein a specific PDCCH resource is configured through the system message.

[0167] It should be noted that the aforementioned Figures 3 to 8 The explanation of the method executed by the UE in any embodiment is also applicable to the method executed by the network side device in this embodiment. The implementation principles are similar and will not be repeated here.

[0168] In the data transmission method of the disclosed embodiment, a network-side device sends configured CG SDT resources to a UE; wherein the UE uses the CG SDT resources during the CG SDT process according to the current data transmission phase. Thus, the UE can use appropriate CG SDT resources for data transmission according to the current data transmission phase, thereby improving the UE's data transmission rate and enabling the UE to send more data during the SDT process.

[0169] It should be noted that the above-mentioned possible implementation methods can be executed separately or in combination, and the embodiments of the present disclosure are not limited to this.
