[0055] The present application will be described in further detail below with reference to the accompanying drawings and embodiments.

[0056] To reduce transmission latency and scheduling complexity, the Radio Access Network (RAN) introduces the CG and Time Advance value (TA) of uplink resources. This means that the network configures periodic uplink resources and related transmission parameters for the terminal. When the terminal is in a connected state, the network determines the transport block (TB) for uplink data transmission on the Physical Uplink Shared Channel (PUSCH) based on the network configuration, and achieves time alignment with the network. However, in related technologies, a terminal can only send uplink data when in a connected state. When a terminal switches from a connected state to an inactive state, the inactive terminal cannot transmit uplink data.

[0057] Based on this, the uplink data transmission method, device, terminal and storage medium provided in the embodiments of the present application, when the terminal is in an inactive state, the terminal sends uplink data at least based on CG information, thereby realizing uplink data transmission of the terminal in an inactive state.

[0058] The embodiment of the present application provides an uplink data transmission method, which is applied to a terminal, such as Figure 1 As shown, the method includes:

[0059] Step 101: When the terminal is in an inactive state, uplink data is sent based on first information.

[0060] Among them, the first information at least includes CG information.

[0061] Here, when the terminal is in an inactive state, the TB used to transmit uplink data is determined on the PUSCH at least based on the CG information configured on the network side, and the uplink data is sent to the network side on the determined TB.

[0062] In actual applications, the CG information is configured by the network side for the terminal. The terminal can use the CG information configured by the network side in the connected state, or the network side can configure the CG information for the terminal in the inactive state.

[0063] Based on this, in one embodiment, the method further includes:

[0064] When the terminal enters an inactive state from a connected state, if the terminal is configured with CG information in the connected state, retain all or part of the CG information of the terminal in the connected state; or, if the terminal is not configured with CG information in the connected state, configure CG information for the terminal.

[0065] Here, when the terminal switches from a connected state to an inactive state, if the terminal already has CG information in the connected state, the terminal retains all or part of the CG information in the connected state. Retaining the CG information can be understood as the retained CG information still being effective when the terminal is in an inactive state, that is, the terminal can send uplink data on the uplink resources authorized by the retained CG information in the inactive state. In addition, when the terminal switches from a connected state to an inactive state, if the terminal does not have CG information configured in the connected state, the network side can configure the CG information in the inactive state for the terminal, and the terminal can send uplink data on the uplink resources authorized by the CG information configured by the network side in the inactive state.

[0066] In the case where the terminal retains the CG information in the connected state, the CG information that needs to be retained can be determined through the RRC instructions on the network side. For example, the network side indicates the number of the CG information that needs to be retained through ConfiguredGrantConfigIndex, and the terminal determines the CG information that needs to be retained based on ConfiguredGrantConfigIndex.

[0067] Based on this, in one embodiment, the second information is carried in an RRCreleasemessage.

[0068] Here, ConfiguredGrantConfigIndex can be carried in the RRCreleasemessage, and the terminal determines the CG information that needs to be retained based on ConfiguredGrantConfigIndex.

[0069] In one embodiment, the second information includes a SuspendConfig field in an RRCreleasemessage.

[0070] Here, the network side can write ConfiguredGrantConfigIndex in the SuspendConfig field in the RRCreleasemessage, and the terminal determines the CG information that needs to be retained based on ConfiguredGrantConfigIndex.

[0071] When implementing the solution of the embodiment of the present application, the terminal can transmit uplink data or part of the RRC resume information to the network side in an inactive state.

[0072] Based on this, in one embodiment, sending uplink data based on the first information includes:

[0073] Use the uplink resources authorized by the CG information to send uplink data.

[0074] Here, when the terminal has uplink data to be transmitted in an inactive state, the uplink data is sent using the uplink resources authorized by the CG information.

[0075] In one embodiment, sending uplink data based on the first information further includes:

[0076] Use the uplink resources authorized by the CG information to send part of the RRC resume information.

[0077] Here, in addition to using the uplink resources authorized by the CG information to send uplink data, the terminal can also use the uplink resources authorized by the CG information to send part of the RRC resume information. Figure 2 The following is a schematic diagram of an implementation of the RRC resume process in the related art, including:

[0078] Step 1: The terminal initiates a resume request RRCConnectionResumeRequest to the network side, such as the Evolved Universal Terrestrial Radio Access Network (EUTRAN).

[0079] Step 2: The network sends RRCConnectionResume to the terminal.

[0080] Step 3: The terminal sends RRCConnectionResumeComplete to the network side, so that the terminal switches from the inactive state to the connected state.

[0081] When implementing the solution of the embodiment of the present application, the terminal uses the uplink resources authorized by the CG information to send the RRCresume information, and the purpose is not to restore the terminal from the inactive state to the connected state. Therefore, the RRC resume information sent by the terminal to the network side is the same as the RRC resume information sent by the terminal to the network side. Figure 2 In the resume process shown, the RRC resume information sent by the terminal to the network side is not completely different. Therefore, here the terminal sends partial RRC resume information using the uplink resources authorized by the CG information in the inactive state.

[0082] In actual applications, considering the processing load of the terminal in the inactive state, the uplink data transmitted by the terminal in the connected state is different from the uplink data transmitted by the terminal in the inactive state. For example, compared with the uplink data transmitted by the terminal in the connected state, the amount of uplink data transmitted by the terminal in the inactive state is smaller, or only part of the uplink data is transmitted.

[0083] Based on this, in one embodiment, the sending of uplink data using the uplink resources authorized by the CG information includes:

[0084] Use the uplink resources authorized by the CG information to send at least one of the following uplink data:

[0085] Data on the set DRB;

[0086] Data on the set QoS flow;

[0087] Set the data on the LCH.

[0088] Here, when the terminal is in an inactive state, the uplink resources authorized by the CG information are used to send data on one or more specified DRBs, or to send data on one or more specified QoS flows, or to send data on one or more specified LCHs. In this way, by specifying DRBs, specifying QoS flows, or specifying LCHs, uplink data transmission for some high-priority or low-latency services of the terminal can be achieved in an inactive state, thereby ensuring the communication efficiency of the terminal. Moreover, for low-priority or high-latency services, the relevant uplink data is not transmitted in the inactive state. If this part of the uplink data needs to be transmitted, the terminal enters the connected state from the inactive state through the resume process, and completes the transmission of this part of the uplink data in the connected state. In this way, the uplink data transmitted in the inactive state and the uplink data transmitted in the connected state are specifically distinguished, thereby ensuring the low power consumption and low-load operation requirements of the terminal in the inactive state.

[0089] In one embodiment, the sending of uplink data using uplink resources authorized by CG information includes:

[0090] Use the uplink resources authorized by the CG information to send uplink data with a data amount less than or equal to a set data amount; wherein the set data amount includes one of the following:

[0091] The set MAC buffer data volume;

[0092] The set PDCP buffer data volume;

[0093] The set number of MAC PDUs;

[0094] The set number of RLC PDUs;

[0095] The number of PDCP PDUs to be configured;

[0096] Set the number of IP packets.

[0097] Here, it can be understood as setting an upper limit on the amount of uplink data sent by the terminal in the inactive state. Uplink data that is less than or equal to the set data amount can be sent in the inactive state. For example, the amount of data in the MAC buffer is detected. When the amount of data in the MAC buffer is less than the corresponding set data amount, the data in the MAC buffer is transmitted uplink to the network side in the inactive state. For data that exceeds the set data amount, the terminal enters the connected state from the inactive state through the resume process and completes the transmission of this part of the uplink data in the connected state. In this way, the amount of uplink transmission in the inactive state and the amount of uplink transmission data in the connected state are specifically distinguished, ensuring the low power consumption and low load operation requirements of the terminal in the inactive state.

[0098] In practical applications, for some industrial wireless sensor network scenarios, uplink data packets are small, and the positional relationship between the terminal and the base station is relatively fixed. Therefore, when the terminal transmits uplink data, time alignment with the network based on the time interval (TA) is not required. However, in other scenarios, signal transmission is delayed in space. For example, as the terminal moves away from the base station, the signal sent by the terminal will arrive at the base station later and later, causing inter-symbol interference (ISI). Therefore, the RAN uses the time interval (TA) to instruct the terminal to send signals earlier, thereby achieving time alignment with the network.

[0099] Based on this, in one embodiment, the first information further includes a TA; when uplink data is sent using uplink resources authorized by the CG information, the method further includes:

[0100] Uplink data is sent based on the TA.

[0101] When the terminal enters the inactive state from the connected state, it retains the TA currently configured by the network side and achieves time alignment with the network side based on the TA when sending uplink data in the inactive state. Here, the terminal obtains the TA value through the following ways: 1. The 12-bit Timing Advance Command (TAC) contained in MSG2 of the four-step random access procedure or MSGB of the two-step random access procedure; 2. The TAC in the downlink MAC control element (CE) sent by the network side.

[0102] When implementing the solution of the embodiment of the present application, the terminal may be in a mobile state, and the distance between the terminal and the base station may change continuously, resulting in the TA previously configured by the network side for the terminal being unavailable. Based on this, in one embodiment, when the uplink data fails to be transmitted correctly or the error transmission rate of the uplink data exceeds a set threshold, one of the following is performed:

[0103] Update the value of TA to 0;

[0104] Trigger the resume process.

[0105] Considering that changes in the distance between the terminal and the base station may cause the TA previously configured for the terminal on the network side to become invalid, if uplink data fails to be transmitted correctly or the error rate exceeds the set threshold, the TA value is updated to 0. In other words, the time to send uplink data is no longer adjusted based on the TA configured by the network side. Alternatively, if uplink data fails to be transmitted correctly or the error rate exceeds the set threshold, the terminal no longer considers transmitting uplink data in the inactive state, but instead triggers the resume process and enters the connected state for uplink data transmission.

[0106] In one embodiment, the set threshold is configured by the network side for the terminal before the terminal enters the inactive state.

[0107] In one embodiment, when the uplink data fails to be correctly transmitted or the error transmission rate of the uplink data exceeds a set threshold, one of the following is determined to be performed based on the configuration of the network side:

[0108] Update the value of TA to 0;

[0109] Trigger the resume process.

[0110] Here, when the uplink data fails to be transmitted correctly or the error rate of the uplink data exceeds a set threshold, the terminal updates the TA to 0 or triggers the resmue process based on the RRC command sent by the network side or the indication in the network broadcast.

[0111] In related technologies, terminals can only realize uplink data transmission after entering the connected state. However, based on the uplink data transmission method provided in the embodiment of the present application, when the terminal is in an inactive state, the terminal sends uplink data at least based on the CG information, thereby realizing uplink data transmission of the terminal in the inactive state.
