[0055] It should be further understood that the terms "comprising" or "including" indicate the presence of the aforementioned features, steps, operations, elements, components, types, and / or groups, but do not exclude the presence, occurrence, or addition of one or more other features, steps, operations, elements, components, types, and / or groups.

[0056] In this application, terms such as "exemplary," "in some embodiments," and "in other embodiments" are used to indicate that something is an example, illustration, or description. Any embodiment or design described as "exemplary" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Rather, the term "exemplary" is used to present the concept in a specific manner.

[0057] To facilitate understanding of the technical solutions of this application, the following describes the scenarios in which the embodiments of this application are applicable.

[0058] Figure 1 This is a schematic diagram illustrating an application scenario provided by an embodiment of this application. For example... Figure 1 As shown, it includes network device 101 and terminal 102, which can communicate with each other.

[0059] It should be noted that, Figure 1 The application scenario and the number of network devices and terminals in the scenario are given only as examples. Optionally, the application scenario may also include other numbers of network devices and terminals, which are not limited in this application.

[0060] The network device in this application is a device with wireless transceiver capabilities. This includes, but is not limited to: evolved node Bs (eNBs or eNodeBs) in Long Term Evolution (LTE), base stations (gNodeBs or gNBs) or multi-transmission and receiving points (M-TRPs) in New Radio (NR), base stations in subsequent evolution systems, access nodes in Wireless Fidelity (WiFi) systems, wireless relay nodes, wireless backhaul nodes, etc. Base stations can be: macro base stations, micro base stations, pico base stations, small cells, relay stations, or balloon stations, etc. A base station can contain one or more co-located or non-co-located TRPs.

[0061] The terminal in this application is a device with wireless transceiver capabilities. The terminal can be deployed on land, including indoors or outdoors, handheld, wearable, or vehicle-mounted; it can also be deployed on water (such as on ships); and it can be deployed in the air (e.g., on airplanes, balloons, and satellites). The terminal can be a mobile phone, tablet computer, computer with wireless transceiver capabilities, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal in industrial control, vehicle-mounted terminal device, wireless terminal in self-driving, wireless terminal in remote medical care, wireless terminal in smart grids, wireless terminal in transportation safety, wireless terminal in smart cities, wireless terminal in smart homes, wearable terminal devices, etc. The terminal involved in the embodiments of this application may also be referred to as user equipment (UE), access terminal, vehicle-mounted terminal, industrial control terminal, UE unit, UE station, mobile station, mobile station, remote station, remote user equipment, mobile device, wireless communication device, UE agent, or UE device, etc. The terminal may also be fixed or mobile.

[0062] Figure 2 This is a schematic diagram illustrating the process of initiating MT-SDT data transmission in related technologies. For example... Figure 2As shown, when the terminal is inactive, if the base station has MT-SDT data to send to the terminal, it first needs to page the corresponding terminal via a Uu paging message. The terminal receives the Uu paging message within the configured paging period. After receiving the Uu paging message, if the paging cause carried by the Uu paging message is MT-SDT, the terminal initiates RRC recovery. The subsequent process is similar to the MO-SDT data transmission process, that is, the MO-SDT process is reused to send MT-SDT data.

[0063] The above-described process for initiating MT-SDT data transmission has the following problems:

[0064] 1. Sending MT-SDT data requires borrowing the MO-SDT process, which leads to complex processes and configurations, unnecessary overhead, and increased base station load.

[0065] 2. Increased latency in MT-SDT data transmission and processing.

[0066] 3. If the uplink process of MO-SDT fails, MT-SDT data cannot be sent either, for example, if the uplink timing advance (TA) is invalid or the downlink reference signal received power (RSRP) is invalid.

[0067] To address the aforementioned technical problems, this application provides a communication method in which, after sending a first paging message to a terminal, the network device directly sends MT-SDT data to the terminal based on pre-configured SDT radio parameters; and after receiving the first paging message, the terminal directly receives the MT-SDT data based on the pre-configured SDT radio parameters. This application does not rely on the MO-SDT process when sending MT-SDT data, simplifying the process and reducing the transmission latency of MT-SDT data and the load on the network device.

[0068] The technical solutions shown in this application will be described in detail below through specific embodiments. It should be noted that the following embodiments can exist independently or in combination with each other. For the same or displayed content, it will not be described again in different embodiments.

[0069] Figure 3 A flowchart illustrating a communication method provided in an embodiment of this application. Figure 1 .like Figure 3 As shown, the method includes:

[0070] S301. The network device sends a first paging message, and the corresponding terminal receives the first paging message, which instructs the terminal to receive MT-SDT data.

[0071] Before executing the method of this application, the terminal is in an inactive state.

[0072] The first paging message instructing the terminal to receive MT-SDT data may mean that the paging reason carried in the first paging message is direct MT-SDT (MT-SDT-direct).

[0073] After receiving a Radio Access Network (RAN) paging message from the core network, the network device can send a first paging message to the terminal. The paging reason carried in the RAN paging message is MT-SDT.

[0074] After receiving a RAN paging message, the network device needs to check whether the conditions for directly initiating MT-SDT transmission are met. That is, the network device needs to check whether SDT radio parameters have been configured for the terminal. If the conditions for directly initiating MT-SDT transmission are met (i.e., SDT radio parameters have been configured for the terminal), the network device can directly send a first paging message to the terminal. The paging reason carried in the first paging message is MT-SDT-direct. If the conditions for directly initiating MT-SDT transmission are not met (i.e., SDT radio parameters have not been configured for the terminal), the traditional method is used to initiate the transmission of MT-SDT data (such as sending MT-SDT data during the multiplexing of MO-SDT).

[0075] S302. The network device sends MT-SDT data based on the SDT wireless parameters; correspondingly, the terminal receives MT-SDT data based on the SDT wireless parameters.

[0076] MT-SDT data can be carried on the Physical Downlink Shared Channel (PDSCH). After decoding the Physical Downlink Control Channel (PDCCH), the terminal can receive the PDSCH carrying MT-SDT data.

[0077] Considering the processing latency of the terminal, the network device can start scheduling the PDCCH after sending the first paging message, with an interval of N time slots. That is, there is an interval of N time units between the end time slot of the first paging message transmission and the start time slot of the PDCCH transmission. The time unit can be a symbol, time slot, etc. N is an integer greater than 0, and the specific value of N can be determined according to the actual situation. This application does not impose any restrictions on this.

[0078] In one possible implementation, the SDT wireless parameters include at least one of the following:

[0079] (1) First identifier, the first identifier is used to identify MT-SDT data.

[0080] That is, the network device carries a first identifier in the downlink signal carrying MT-SDT data, and the terminal can demodulate only the downlink signal carrying the first identifier, thereby reducing terminal monitoring overhead and the probability of mismodulation.

[0081] For example, the first identifier can be a Radio Network Temporary Identifier (RNTI). Since the first identifier is used to identify MT-SDT data, the first identifier can also be written as MT-SDT-RNTI. This application does not limit this.

[0082] (2) First Bandwidth Part (BWP): The first BWP is used to transmit MT-SDT data.

[0083] The first BWP can refer to the initial downlink BWP.

[0084] When configuring the first BWP for a terminal, the network device may configure at least one of the following for the terminal: BWP identifier, BWP frequency domain location, bandwidth, subcarrier spacing, cyclic prefix (CP), etc. This application does not impose any restrictions on this.

[0085] Since the first BWP is used to transmit MT-SDT data, the first BWP can also be referred to as MT-SDT-BWP, and this application does not limit it in this way.

[0086] (3) First search space, which is used to transmit MT-SDT data.

[0087] The first search space can be determined based on the listening period and time slot offset. That is, when configuring the first search space for the terminal, the network device can configure the corresponding listening period and time slot offset for the terminal.

[0088] The first search space is bound to the corresponding control resource set (CORESET). That is, when the network device configures the first search space on the terminal, it must not only configure the corresponding listening period and time slot offset for the terminal, but also configure the bound CORESET number.

[0089] Since the first search space is used to transmit MT-SDT data, the first search space can also be denoted as MT-SDT-SS, and this application does not limit it in this way.

[0090] (4) First uplink resource, the first uplink resource is used to transmit the first feedback, the first feedback is the reception feedback of MT-SDT data.

[0091] The first uplink resource can be either a Physical Uplink Control Channel (PUCCH) resource or a Physical Uplink Shared Channel (PUSCH) resource.

[0092] Network devices can detect uplink control information (UCI) on the first uplink resource to determine the content of the first feedback.

[0093] (5) First timer, the first timer is used to indicate the duration of MT-SDT data detection.

[0094] For example, the interval between the end time of receiving the first paging message and the start time of the first timer can be M time units. These time units can be symbols, time slots, etc., and M is an integer greater than or equal to 0. During the operation of the first timer, the terminal can receive MT-SDT data. After the first timer expires, the current MT-SDT data transmission stops.

[0095] Since the first timer is used to indicate the duration of MT-SDT data detection, the first timer can also be referred to as MT-SDT timer, and this application does not limit it to this.

[0096] Based on the above description, the SDT wireless parameters may include items (1), (2) and (3), or items (1), (2), (3) and (4), or items (1), (2), (3) and (5), or items (1), (2), (3), (4) and (5).

[0097] It should be noted that SDT wireless parameters can also be called SDT configuration parameters, wireless parameters, etc., and this application does not limit them.

[0098] exist Figure 3 In the illustrated embodiment, after sending a first paging message to the terminal, the network device directly sends MT-SDT data to the terminal based on pre-configured SDT radio parameters; after receiving the first paging message, the terminal directly receives MT-SDT data based on the pre-configured SDT radio parameters. This application does not rely on the MO-SDT process when sending MT-SDT data, simplifying the process and reducing the transmission latency of MT-SDT data and the load on the network device.

[0099] Based on the above embodiments, the following details how to configure SDT wireless parameters.

[0100] Figure 4 A flowchart illustrating a communication method provided in an embodiment of this application. Figure 2 .like Figure 4 As shown, the method includes:

[0101] S401. The network device sends an RRC release message, and the terminal receives the corresponding RRC release message, which includes SDT radio parameters.

[0102] It should be noted that the relevant descriptions of SDT wireless parameters can be found in the corresponding descriptions in S302, and will not be repeated here.

[0103] After determining the SDT wireless parameters, network devices can save the SDT wireless parameters.

[0104] After receiving the SDT radio parameters, the terminal can save the SDT radio parameters, and the terminal can enter the inactive state from the connected state based on the indication of the RRC release message.

[0105] After sending SDT radio parameters to the terminal, the network device can also send System Information Block (SIB) 1 to the terminal. SIB1 may include common SDT configuration parameters. For example, common SDT configuration parameters may include RSRP related thresholds, SDT data volume thresholds, PDSCH common configuration, PDCCH common configuration, Time Division Duplex (TDD) uplink and downlink time slot configuration, etc. This application does not impose any restrictions on these parameters.

[0106] exist Figure 4 In the implementation shown, the network device configures the SDT radio parameters for the terminal while sending the RRC release message to the terminal, so that the terminal can directly receive MT-SDT data based on the SDT radio parameters after receiving the first paging message.

[0107] It should be noted that, Figure 3 The illustrated embodiments and Figure 4 The illustrated embodiments can be combined.

[0108] Based on the above, the following section uses a network device as a receiving base station to illustrate the solution of this application.

[0109] Figure 5 A flowchart illustrating a communication method provided in an embodiment of this application. Figure 3 .like Figure 5 As shown, the method includes:

[0110] S501: Receive the RRC release message sent by the base station. Correspondingly, the terminal receives the RRC release message, which includes SDT radio parameters.

[0111] It should be noted that the execution process of S501 can be referred to the execution process of S401, and will not be repeated here.

[0112] S502, the terminal enters an inactive state.

[0113] S503, User Plane Function (UPF), sends downlink user data to the base station that served the previous service.

[0114] S504. The last serving base station sends a RAN paging message to the receiving base station, which carries MT-SDT information.

[0115] The MT-SDT information may include downlink user data, the terminal's SDT context information, and the paging reason (also known as a trigger instruction, indicating that the RAN paging message is a paging message used to trigger MT-SDT). The terminal's SDT context information may include the terminal identifier, security information (security key or security context), SDT resource configuration, and Quality of Service (QoS) information. This application does not impose any limitations on this.

[0116] S505: The base station receives a first paging message sent to the terminal, and the first paging message carries MT-SDT information.

[0117] The MT-SDT information may include some SDT context information and a paging reason, which is MT-SDT-direct.

[0118] Upon receiving the first paging message, the terminal prepares to receive MT-SDT data.

[0119] S505, Receive PDCCH sent from base station to terminal.

[0120] The PDCCH can carry downlink authorization for sending MT-SDT data.

[0121] S506, Receive the PDSCH carrying MT-SDT data sent by the base station to the terminal.

[0122] The following describes the data transmission process for MT-SDT in this application.

[0123] For network devices, the following steps are included:

[0124] (1) The network device has sent the first paging message and can start scheduling PDCCH in the first time slot. The first time slot is N time slots apart from the end time slot of the transmission of the first paging message. N is an integer greater than 0. The PDCCH carries the downlink authorization to send MT-SDT data.

[0125] (2) Send PDSCH at a time interval of K0 from the start of the PDCCH. The PDSCH carries the MT-SDT data to be sent.

[0126] (3) When PUCCH or PUSCH resources are configured, detect the uplink UCI, determine the Hybrid Automatic Repeat-reQuest (HARQ) feedback content, and end the current MT-SDT transmission if the feedback content is ACK; end the current MT-SDT transmission if the feedback content is NACK and the maximum number of retransmissions has been reached; and schedule MT-SDT data retransmission if the feedback content is NACK and the maximum number of retransmissions has not been reached.

[0127] (4) If PUCCH and PUSCH resources are not configured, retransmission (i.e., retransmission of PDCCH and PDSCH) is directly scheduled on the downlink (i.e., on the time-frequency resources indicated by the SDT radio parameters). Specifically, if the maximum number of retransmissions is reached, the current MT-SDT transmission is terminated; if the maximum number of retransmissions is not reached, MT-SDT data retransmission is scheduled.

[0128] For the terminal, the following steps are included:

[0129] (1) When the terminal receives the first paging message and the first identifier, the first BWP and the first search space are all configured or valid, the PDCCH is detected and the first timer is started.

[0130] (2) Continue to receive MT-SDT data if Downlink Control Information (DCI) is successfully detected.

[0131] (3) When PUCCH or PUSCH resources are configured, the results of MT-SDT data reception are fed back to the network device;

[0132] (4) Based on the feedback of MT-SDT data reception results, wait for the next MT-SDT data retransmission or retransmission;

[0133] (5) In the absence of PUCCH and PUSCH resources configured. Specifically, if MT-SDT data is successfully received and decoded, subsequent retransmissions of MT-SDT data will be stopped; if MT-SDT data is not successfully received or decoded, subsequent retransmissions of MT-SDT data will continue to be received.

[0134] (6) If the first timer does not expire, continue to detect PDCCH in the first search space; if the first timer expires, stop the current MT-SDT transmission.

[0135] (7) When the terminal receives a paging message with the paging reason as MT-SDT, the MO-SDT procedure is reused to initiate MT-SDT data transmission.
