Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a data transmission method and related devices. Background Art

[0002] The resources used by the user equipment (UE) to transmit uplink data can be based on the dynamic scheduling of the network or pre-configured grant (CG) resources, which are a set of periodic uplink resources pre-configured by the network. The UE can perform small data transmission (SDT) in an inactive state, including SDT based on random access process and SDT based on pre-configured resources.

[0003] In the SDT process, the first uplink transmission needs to include a radio resource control (RRC) recovery request message for UE identity authentication, and subsequent transmissions need to be performed after the network successfully authenticates the UE. However, for the SDT process based on CG resources, the data of the UE's first uplink transmission on the CG resource has not been successfully received by the network, and the UE may transmit the remaining data on the next CG resource, which will result in the network receiving subsequent data before authenticating the UE.

[0053] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0054] Below, some terms in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

[0055] The "at least one" involved in the embodiments of the present application refers to one or more, and "plurality" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b, or c can represent: a, b, c, ab, ac, bc, or abc, where a, b, c can be single or multiple.

[0056] Furthermore, unless otherwise specified, ordinal numbers such as "first" and "second" mentioned in the embodiments of the present application are used to distinguish multiple objects, and are not used to limit the order, timing, priority or importance of multiple objects. For example, the first information and the second information are only used to distinguish different information, and do not indicate the difference in content, priority, sending order or importance of the two types of information.

[0057] In order to facilitate the understanding of the present application, the concepts involved in the present application are first explained.

[0058] Early data transmission (EDT): In long term evolution (LTE), EDT has been introduced. During this process, the UE may always remain in the idle state, suspended state, and inactive state to complete the transmission of small uplink and / or downlink data packets. In terms of configuration, the network will configure the maximum transport block (TB) size allowed by the current network in the system information block (SIB). The UE determines the amount of data to be transmitted. If it is less than the maximum TB size allowed for transmission, the UE can initiate EDT transmission; otherwise, the UE uses the normal connection establishment process to enter the connected state to transmit data.

[0059] See also Figure 1 , Figure 1 Figure 2 is a schematic diagram of the EDT process. Figure 1 As shown, when the cell where the UE initiates EDT is the same as the last serving cell, the base station can directly submit the uplink data to the core network after receiving the connection recovery request and uplink data sent by the UE.

[0060] Preconfigured uplink resource (PUR): For narrowband Internet of things (NB-IoT) and enhanced machine-type communication (eMTC) scenarios, a method of using PUR for data transmission in idle state is introduced. PUR is only valid in the currently configured cell, that is, when the UE detects a cell change and initiates random access in the new cell, the UE needs to release the PUR configured in the original cell. Figure 2 , Figure 2 Schematic diagram of the PUR transmission process.

[0061] Configured grant (CG): The resources used by the UE to transmit uplink data can be based on the network's dynamic scheduling (indicated by downlink control information (DCI)) or CG resources, which are a set of periodic uplink resources preconfigured by the network. Uplink CG resources can be divided into two types: type 1 and type 2.

[0062] CG type 1 is configured by radio resource control (RRC) parameters, including time domain resources, frequency domain resources, demodulation reference signal (DMRS), open-loop power control, modulation and coding scheme (MCS), waveform, redundancy version, number of repetitions, frequency modulation, hybrid automatic repeat request (HARQ) process, etc. After receiving the high-level configuration, the UE can use the configured CG type 1 resources for uplink data transmission, and no additional activation steps are required.

[0063] CG type 2 is also configured through RRC parameters, but the activation of the configured CG type 2 resources is indicated by the DCI scrambled by the configured scheduling radio network temporary identifier (CS-RNTI), and the transmission resources and transmission parameters including time domain resources, frequency domain resources, DMRS, MCS, etc. are configured at the same time. After receiving the high-level configuration, the UE cannot use the CG type 2 resources and must wait until the corresponding DCI activation command and configuration information are received before uplink data transmission can be performed.

[0064] The UE determines the HARQ process corresponding to the CG resource according to the network configuration. When the UE completes uplink data transmission using the CG resource corresponding to a certain HARQ process, the timer is started. During the timer operation, the UE cannot use the CG resource with the same HARQ process to transmit new data to avoid the data in the HARQ buffer being overwritten by other data. When the timer times out, it indicates that the data transmitted by the corresponding HARQ process has been successfully received by the network.

[0065] Small data transmission (SDT): In the 5th generation (5G) new radio (NR) system, there are three RRC states: RRC idle state, RRC inactive state and RRC connected state. Among them, the RRC inactive state is a new state introduced by the 5G system from the perspective of energy saving. For UEs in the RRC inactive state, the radio bearer and all radio resources will be released, but the UE side and the base station side retain the UE access context to quickly restore the RRC connection. The network usually keeps UEs with infrequent data transmission in the RRC inactive state.

[0066] Prior to Release 16, UEs in the RRC inactive state did not support data transmission. When uplink or downlink data arrived, the UE needed to restore the connection and release it to the inactive state after data transmission was completed. For UEs with small data volumes and low transmission frequencies, such a transmission mechanism would result in unnecessary power consumption and signaling overhead. Therefore, Release 17 proposed SDT technology in the RRC inactive state, including SDT based on random access procedures and SDT based on preconfigured resources (e.g., CG type 1).

[0067] For both the random access process-based SDT (RA-SDT) and the pre-configured resource-based SDT (CG-SDT) schemes, a common control channel (CCCH) message needs to be included in the first uplink transmission, and the CCCH message may be an existing RRC recovery request message.

[0068] SDT also supports subsequent transmissions, that is, after completing the first uplink data transmission, the UE can continue to transmit uplink data or receive downlink data in an inactive state. For CG-SDT, subsequent transmissions can be based on dynamic scheduling of the network or on CG.

[0069] The RRC recovery request message contains an inactive radio network temporary identifier (I-RNTI), a resume medium access control identify (Resume MAC-I) and a resume cause (Resume cause), wherein I-RNTI is the UE identifier, which is used by the base station to find the UE context according to the I-RNTI; Resume MAC-I is used by the base station to authenticate the UE; and Resumecause is used to indicate the reason why the UE initiated the connection request.

[0070] During the SDT process, the first uplink transmission needs to include an RRC recovery request message, which is used by the base station to determine the UE identity, find the UE access context, and authenticate the UE identity. Subsequent transmissions need to be performed after the network successfully authenticates the UE.

[0071] For the CG-SDT process, the resource used for the first uplink data transmission is the CG, and the resource used for subsequent data transmission can be either the CG or the resource based on dynamic scheduling. If the data of the first uplink transmission of the UE on the CG resource has not been successfully received by the network, the UE may transmit the remaining data on the next CG resource, which will result in the network receiving subsequent data before authenticating the UE.

[0072] The background technology of the present application is introduced above, and the technical features of the embodiments of the present application are introduced below.

[0073] See also Figure 3 , Figure 3 Schematic diagram of a communication system applicable to the embodiment of the present application. Figure 3 As shown, the communication system includes a network device 301 and a terminal device 302. The terminal device 302 in the RRC inactive state performs the CG-SDT process when the first condition is met. The first condition includes: all the data to be transmitted come from the radio bearer that allows the triggering of SDT, the amount of data to be transmitted is less than or equal to the data amount threshold configured by the network device 301, the downlink reference signal received power (reference signal received power, RSRP) measurement result is greater than or equal to the RSRP threshold for performing SDT, there are CG resources on the selected carrier and synchronization signal block (synchronization signal block, SSB), there are valid timing advance (timing advance, TA) and next hop chaining count (next hop chaining count, NCC) and other information. The terminal device 302 sends the first uplink data on the first CG resource, wherein the first uplink data includes the first information, and the first information is used for the identity authentication of the terminal device 302. After the first duration, the terminal device 302 sends the second uplink data on the second CG resource. It can be seen that the terminal device 302 sends the first uplink data on the first CG resource, and after the first duration, sends the second uplink data on the second CG resource. The setting of the first duration ensures that the terminal device 302 can send the second uplink data only after the network device 301 authenticates the terminal device 302. This avoids the problem of receiving subsequent data before the network authenticates the UE during the SDT process based on the CG resource.

[0074] See also Figure 4 , Figure 4 A schematic diagram of a data transmission method provided in an embodiment of the present application, which data transmission method can be applied to Figure 3 The communication system shown in FIG. Figure 4 As shown, the data transmission method includes:

[0075] S401. The terminal device sends first uplink data on a first pre-configured CG resource, wherein the first uplink data includes first information, and the first information is used for identity authentication of the terminal device.

[0076] Optionally, a terminal device in an RRC inactive state performs a CG-SDT process when the first condition is met. The first condition includes: all data to be transmitted comes from a radio bearer that allows triggering SDT, the amount of data to be transmitted is less than or equal to the data volume threshold configured by the network device, the downlink RSRP measurement result is greater than or equal to the RSRP threshold for performing SDT, CG resources exist on the selected carrier and SSB, and there are valid TA and NCC information.

[0077] Optionally, the first uplink data includes an RRC message, the RRC message may be an RRC recovery request message, and the first information is carried by the RRC recovery request message.

[0078] Optionally, after the terminal device sends the first uplink data on the first CG resource, it also includes: starting a first timer.

[0079] Optionally, during the operation of the first timer, the terminal device listens to a first DCI encrypted by a first RNTI, wherein the first DCI is used to instruct the terminal device to resend first uplink data; if the first DCI is received, the terminal device resends the first uplink data; after the terminal device resends the first uplink data, the first timer is restarted.

[0080] In one possible implementation, the terminal device resends the first uplink data, including: during the operation of the first timer, the terminal device resends the first uplink data on a third CG resource, wherein the HARQ process corresponding to the third CG resource is the same as the HARQ process corresponding to the first CG resource; or, during the operation of the first timer, when the second timer times out, the terminal device resends the first uplink data on the third CG resource, and after the terminal device resends the first uplink data, the second timer is restarted.

[0081] S402. After the first duration, the terminal device sends the second uplink data on the second CG resource.

[0082] In the above method, the terminal device sends the first uplink data on the first CG resource, and after the first duration, sends the second uplink data on the second CG resource. The setting of the first duration ensures that the terminal device can send the second uplink data only after the network device authenticates the terminal device. This avoids the problem of receiving subsequent data before the network authenticates the UE during the SDT process based on CG resources.

[0083] See also Figure 5 , Figure 5 A schematic diagram of another data transmission method provided in an embodiment of the present application, which data transmission method can be applied to Figure 3 The communication system shown in FIG. Figure 5 As shown, the data transmission method includes:

[0084] S501. The terminal device sends first uplink data on the first CG resource, wherein the first uplink data includes first information, and the first information is used for identity authentication of the terminal device.

[0085] Specifically, a terminal device in an RRC inactive state performs a CG-SDT process when the first condition is met. The first condition includes: all data to be transmitted comes from a radio bearer that allows triggering SDT, the amount of data to be transmitted is less than or equal to the data volume threshold configured by the network device, the downlink RSRP measurement result is greater than or equal to the RSRP threshold for executing SDT, CG resources exist on the selected carrier and SSB, and there are valid TA and NCC information.

[0086] Optionally, the first uplink data includes an RRC message, the RRC message may be an RRC recovery request message, and the first information is carried by the RRC recovery request message.

[0087] S502: The terminal device starts a first timer.

[0088] Specifically, after the terminal device sends the first uplink data, the first timer is started. During the operation of the first timer, the terminal device does not use the CG resource with the same HARQ process as the first CG resource to send new data, and the terminal device does not use the CG resource with a different HARQ process from the first CG resource to send new data.

[0089] S503: While the first timer is running, the terminal device monitors the first DCI encrypted by the first RNTI. If the first DCI is received, the terminal device resends the first uplink data and restarts the first timer.

[0090] Specifically, during the operation of the first timer, the terminal device monitors the first DCI encrypted by the network device using the first RNTI, wherein the first DCI is used to instruct the terminal device to resend the first uplink data. If the terminal device receives the first DCI, it resends the first uplink data. After the terminal device resends the first uplink data, it restarts the first timer.

[0091] In one possible implementation, the terminal device resends the first uplink data, including: during the operation of the first timer, the terminal device resends the first uplink data on a third CG resource, wherein the HARQ process corresponding to the third CG resource is the same as the HARQ process corresponding to the first CG resource; or, during the operation of the first timer, when the second timer times out, the terminal device resends the first uplink data on the third CG resource, and after the terminal device resends the first uplink data, the second timer is restarted.

[0092] S504. When the first timer times out, the terminal device sends the second uplink data on the second CG resource.

[0093] Specifically, when the first timer times out, the terminal device sends second uplink data on a second CG resource, wherein the HARQ process corresponding to the second CG resource is the same as or different from the HARQ process corresponding to the first CG resource.

[0094] In the above method, the terminal device sends the first uplink data on the first CG resource, and the first uplink data includes the first information, and the first information is used for the identity authentication of the terminal device. After sending the first uplink data, the terminal device starts the first timer. After the first timer times out, the terminal device sends the second uplink data on the second CG resource. It can be seen that the setting of the first timer ensures that the network device successfully receives the first uplink data and authenticates the terminal device. The terminal device can send the second uplink data only after the first timer times out. It avoids the problem of receiving subsequent data before the network authenticates the UE during the SDT process based on CG resources.

[0095] See also Figure 6 , Figure 6 A schematic diagram of another data transmission method provided in an embodiment of the present application, which data transmission method can be applied to Figure 3 The communication system shown in FIG. Figure 6 As shown, the data transmission method includes:

[0096] S601. The terminal device sends first uplink data on the first CG resource, wherein the first uplink data includes first information, and the first information is used for identity authentication of the terminal device.

[0097] Specifically, a terminal device in an RRC inactive state performs a CG-SDT process when the first condition is met. The first condition includes: all data to be transmitted comes from a radio bearer that allows triggering SDT, the amount of data to be transmitted is less than or equal to the data volume threshold configured by the network device, the downlink RSRP measurement result is greater than or equal to the RSRP threshold for executing SDT, CG resources exist on the selected carrier and SSB, and there are valid TA and NCC information.

[0098] Optionally, the first uplink data includes an RRC message, the RRC message may be an RRC recovery request message, and the first information is carried by the RRC recovery request message.

[0099] S602: The terminal device starts a first timer.

[0100] Specifically, after the terminal device sends the first uplink data, the first timer is started. During the operation of the first timer, the terminal device does not use the CG resource with the same HARQ process as the first CG resource to send new data, and the terminal device does not use the CG resource with a different HARQ process from the first CG resource to send new data.

[0101] S603: While the first timer is running, the terminal device monitors the first DCI encrypted by the first RNTI. If the first DCI is received, the terminal device resends the first uplink data and restarts the first timer.

[0102] Specifically, during the operation of the first timer, the terminal device monitors the first DCI encrypted by the network device using the first RNTI, wherein the first DCI is used to instruct the terminal device to resend the first uplink data. If the terminal device receives the first DCI, it resends the first uplink data. After the terminal device resends the first uplink data, it restarts the first timer.

[0103] In one possible implementation, the terminal device resends the first uplink data, including: during the operation of the first timer, the terminal device resends the first uplink data on a third CG resource, wherein the HARQ process corresponding to the third CG resource is the same as the HARQ process corresponding to the first CG resource; or, during the operation of the first timer, when the second timer times out, the terminal device resends the first uplink data on the third CG resource, and after the terminal device resends the first uplink data, the second timer is restarted.

[0104] S604: While the first timer is running, the terminal device monitors a second DCI encrypted by a second RNTI, wherein the second DCI is used to indicate that the network device has successfully received the first uplink data.

[0105] Specifically, the second RNTI may be the same as or different from the first RNTI.

[0106] S605: If the terminal device receives the second DCI, stop the first timer.

[0107] S606. The terminal device sends the second uplink data on the second CG resource.

[0108] Specifically, the HARQ process corresponding to the second CG resource is the same as or different from the HARQ process corresponding to the first CG resource.

[0109] In the above method, the terminal device sends the first uplink data on the first CG resource, and the first uplink data includes the first information, and the first information is used for the identity authentication of the terminal device. After sending the first uplink data, the terminal device starts the first timer. After receiving the downlink control information indicating that the network device has successfully received the first uplink data, the terminal device stops the first timer and sends the second uplink data on the second CG resource. It can be seen that the setting of the first timer ensures that the network device successfully receives the first uplink data and authenticates the terminal device. The terminal device can send the second uplink data only after the first timer stops. It avoids the problem that the network receives subsequent data before authenticating the UE during the SDT process based on CG resources.

[0110] See also Figure 7 , Figure 7 A schematic diagram of another data transmission method provided in an embodiment of the present application, which data transmission method can be applied to Figure 3 The communication system shown in FIG. Figure 7 As shown, the data transmission method includes:

[0111] S701. The terminal device sends first uplink data on the first CG resource, wherein the first uplink data includes first information, and the first information is used for identity authentication of the terminal device.

[0112] Specifically, a terminal device in an RRC inactive state performs a CG-SDT process when the first condition is met. The first condition includes: all data to be transmitted comes from a radio bearer that allows triggering SDT, the amount of data to be transmitted is less than or equal to the data volume threshold configured by the network device, the downlink RSRP measurement result is greater than or equal to the RSRP threshold for executing SDT, CG resources exist on the selected carrier and SSB, and there are valid TA and NCC information.

[0113] Optionally, the first uplink data includes an RRC message, the RRC message may be an RRC recovery request message, and the first information is carried by the RRC recovery request message.

[0114] S702: The terminal device starts a first timer.

[0115] Specifically, after the terminal device sends the first uplink data, the first timer is started. During the operation of the first timer, the terminal device does not use the CG resource with the same HARQ process as the first CG resource to send new data.

[0116] S703: While the first timer is running, the terminal device monitors the first DCI encrypted by the first RNTI. If the first DCI is received, the terminal device resends the first uplink data and restarts the first timer.

[0117] Specifically, during the operation of the first timer, the terminal device monitors the first DCI encrypted by the network device using the first RNTI, wherein the first DCI is used to instruct the terminal device to resend the first uplink data. If the terminal device receives the first DCI, it resends the first uplink data. After the terminal device resends the first uplink data, it restarts the first timer.

[0118] In one possible implementation, the terminal device resends the first uplink data, including: during the operation of the first timer, the terminal device resends the first uplink data on a third CG resource, wherein the HARQ process corresponding to the third CG resource is the same as the HARQ process corresponding to the first CG resource; or, during the operation of the first timer, when the second timer times out, the terminal device resends the first uplink data on the third CG resource, and after the terminal device resends the first uplink data, the second timer is restarted.

[0119] S704: During the operation of the first timer, after the first time period has passed since the first uplink data was sent, the terminal device sends the second uplink data on the second CG resource.

[0120] Specifically, during the operation of the first timer, if there is a second CG resource, wherein the HARQ process corresponding to the second CG resource is different from the HARQ process corresponding to the first CG resource, and the terminal device has second uplink data to be transmitted, the terminal device uses the second CG resource to send the second uplink data. The second uplink data includes first information, and the first information can be carried in a MAC control element (CE) or an RRC message. The first information includes ResumeMAC-I. The first duration is the time interval between the first CG resource and the second CG resource, that is, the first duration is the time interval from the terminal device sending the first uplink data to encountering the second CG resource.

[0121] In the above method, the terminal device sends the first uplink data on the first CG resource, and the first uplink data includes the first information, and the first information is used for the identity authentication of the terminal device. After sending the first uplink data, the terminal device starts the first timer. During the operation of the first timer, the terminal device sends the second uplink data on the second CG resource, wherein the second uplink data includes the first information. It can be seen that during the operation of the first timer, when the terminal device uses the CG resources corresponding to other HARQ processes to send new data, it also includes the first information. In this way, regardless of whether the network device successfully receives the first uplink data, after the terminal device sends the second uplink data to the network device, the network device can authenticate the terminal device according to the received second uplink data. This avoids the problem of receiving subsequent data before the network authenticates the UE during the SDT process based on CG resources.

[0125] In an embodiment of the present application, the terminal device sends the first uplink data on the first CG resource, and after the first duration, sends the second uplink data on the second CG resource.
