[0074] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0075] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0076] In the 5G network environment, in order to reduce air interface signaling and quickly restore wireless connections and data services, a new RRC state is defined, namely the RRC_INACTIVE state. This state is different from the RRC idle (RRC_IDLE) state and the RRC active (RRC_ACTIVE) state.

[0077] RRC_IDLE means that mobility is based on cell selection and reselection, paging is initiated by the core network (CN), the paging area is configured by the CN, and there is neither UE access stratum (AS) context nor RRC connection on the base station side.

[0078] RRC_INACTIVE means that mobility is based on cell selection reselection, there is a connection between CN and New Radio (NR), UE AS Context exists on a specific base station, paging is triggered by the Radio Access Network (RAN), and the RAN-based paging area is managed by the RAN. The network-side device knows the UE's location based on the RAN paging area level.

[0079] RRC_CONNECTED means that there is an RRC connection, a UE AS Context exists between the base station and the UE, the network side device knows the location of the UE at the specific cell level, the mobility is the mobility controlled by the network side device, and unicast data can be transmitted between the UE and the base station.

[0080] Figure 1 It is a schematic diagram of RRC state transition according to the related technology, such as Figure 1 As shown, the network side device can control the UE to switch between the three states of RRC_IDLE, RRC_INACTIVE and RRC_CONNECTED according to the actual application scenario requirements.

[0081] Some UE-side RRC parameters in the RRC INACTIVE state can be configured through the RRC Release message. The Information Radio Network Temporary Identifier (I-RNTI) is used to identify the UE INACTIVE context on the base station side and has unique attributes within the base station. The RAN Notification area (RNA) is used to control the area where the UE performs cell selection reselection in the INACTIVE state, that is, the paging range area of ​​RAN initial paging. The RAN paging cycle is used to calculate the paging timing of RAN initial paging. The Next Hop Chaining Count (NCC) is used to indicate the key derived and used during the RRC connection recovery process.

[0082] When the UE moves within the RNA area, it does not need to notify the network side device and follows the mobility behavior under idle, that is, the cell selection and reselection principle. When the UE moves out of the paging area configured by the RNA, the UE triggers the RRC connection recovery process, that is, RRC resumeprocedure, and reacquires the paging area configured by the RNA. When the network side device needs to transmit data to the UE, that is, when downlink data arrives, the 5G base station (gNB) that saves the UE context will trigger all cells in the RNA paging area to send a paging message to the UE, so that the UE in the INACTIVCE state can restore the RRC connection and receive data. In addition, the UE in the INACTIVCE state is configured with an RNA paging area. In this area, in order to ensure the reachability of the UE, the UE needs to perform periodic location updates according to the period configured by the network. The scenarios that trigger the UE to perform RNA updates include the RAN Notification Area Update (RNAU) timer expiration or the UE moving to an area outside the RNA. At present, the RRC INACTIVCE state defined by NR does not support the UE to transmit user plane data.

[0083] The process of small data transmission is defined in Long Term Evolution (LTE). That is, early data transmission (EDT), which is mainly for NB-IoT UE and Emtc UE. When the data initiated by the UE arrives and the data is less than a data threshold broadcast by the system, the UE can trigger EDT based on RACH. EDT mainly includes user plane EDT (UP-EDT) and control plane EDT (CP-EDT). CP-EDT data is mainly transmitted through non-access stratum (NAS) messages. UP-EDT data mainly multiplexes user plane data in RRC messages for transmission.

[0084] The LTE EDT mechanism is a small data transmission mechanism based on 4-step RACH, that is, the network side equipment configures some preamble resources for EDT. If the UE has data transmission, these configured preambles are used to indicate EDT, so that the network side equipment can schedule a larger resource for the UE in the Random Access Response (RAR).

[0085] Optionally, D2D communication can be performed between terminal devices.

[0086] Optionally, the 5G system or 5G network may also be referred to as an NR system or NR network.

[0087] Optionally, the communication system may further include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiment of the present invention.

[0088] It should be understood that the device with communication function in the network / system in the embodiment of the present invention can be called communication device. The communication device may include network side devices and terminal devices with communication function, and the network side devices and terminal devices may be the specific devices described above, which will not be repeated here; the communication device may also include other devices in the communication system, such as network controllers, mobile management entities and other network entities, which are not limited in the embodiment of the present invention.

[0089] It should be understood that the terms "system" and "network" are often used interchangeably in this article. The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0090] According to one embodiment of the present invention, an embodiment of a data transmission method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0091] In this embodiment, a data transmission method running on the above terminal device is provided. Figure 2 is a flow chart of a data transmission method according to one embodiment of the present invention. Figure 2 As shown, the method comprises the following steps:

[0092] Step S20, obtaining a resource configuration message sent by the network side device, wherein the information carried in the resource configuration message includes: first indication information, the first indication information is used to indicate a transmission mode of data to be transmitted on the user equipment, and the data to be transmitted is data corresponding to a logical channel or a user plane bearer;

[0093] Step S22: In an inactive state of radio resource control, data to be transmitted is sent to a network side device based on a resource configuration message.

[0094] Through the above steps, a resource configuration message sent by a network side device can be obtained, and the information carried in the resource configuration message includes a first indication information, and the first indication information is used to indicate a transmission method of data to be transmitted on the user device, and the data to be transmitted is a method of data bound to a logical channel or a user plane bearer. By sending the data to be transmitted to the network side device based on the resource configuration message in an inactive state of wireless resource control, the purpose of UE transmitting small data according to the indication information sent by the network side device is achieved, thereby achieving the technical effect of effectively improving resource utilization, and further solving the technical problem of how to transmit small data when the UE has small data to be transmitted if the network side device configures multiple transmission resources for the UE at the same time in the related technology.

[0095] Optionally, the resource configuration message includes one of the following:

[0096] (1) Radio resource control release message;

[0097] (2) System messages;

[0098] (3) Radio resource control reconfiguration message in connected state.

[0099] That is, the resource configuration message can be an RRC Release message, a system message, or an RRC reconfiguration message in a connected state. Therefore, the present invention does not specifically limit the type of message carrying the first indication information. The optional implementation process of the present invention will be further described in detail below, taking the RRC Release message as an example.

[0100] Optionally, the above method may further include the following execution steps:

[0101] Step S24: Send second indication information to the network side device, where the second indication information is used to indicate that there is data to be transmitted on the user equipment.

[0102] In an optional embodiment, when the UE transmits small data by initiating a 4-step RACH process, the UE can indicate to the network side device that the UE has small data during the data transmission process through a specific preamble (the preamble belongs to a preconfigured preamble group, which is equivalent to the above-mentioned second indication information).

[0103] Optionally, in step S22, sending the data to be transmitted to the network side device based on the resource configuration message may include the following execution steps:

[0104] Step S221, entering an inactive state based on the first indication information and determining a resource type used for data to be transmitted;

[0105] Step S222: In an inactive state, using resources corresponding to the resource type to send data to be transmitted.

[0106] When the network side device indicates the transmission resources of the data to be transmitted (i.e., small data) of the UE in the RRC INACTIVE state in the RRC Release message, the UE receives the RRC Release message from the network side device. The RRC Release message indicates that the UE enters the RRC INACTIVE state, and the RRC Release message can also indicate the resource type that needs to be used if the UE has data to be transmitted after entering the RRC INACTIVE state. The resource type indicated in the RRC Release message can be either a 2-step RACH resource, a 4-step RACH resource, or a Type 1CG resource. The above resource configuration can support the UE to send data to be transmitted in the RRC INACTIVE state. Therefore, after entering the RRC INACTIVE state, the UE will use the resources corresponding to the resource type to send the data to be transmitted. Therefore, the resource configuration message sent by the network side device can indicate which resource should be used to transmit small data when the UE faces multiple available resources based on the UE level, thereby improving resource utilization.

[0107] In a customer-selected embodiment, the indication information indicating which resource the UE uses to transmit small data may be an information indication field in the RRCRelease message, for example: a new indication field SmallDataResourceType is added in the SuspendConfig information element (InformationElement, IE for short) to display the resource type used by the UE to transmit small data in the RRCInactive state.

[0108]

[0109]

[0110] Or it may be an implicit indication, for example: when CG type 1 resources are configured in SuspendConfig or other IEs in the RRC Release message, the UE defaults to using CG type 1 resources for small data transmission without explicitly indicating that the resource type is CG type 1 resources.

[0111] Optionally, in step S222, using the resource corresponding to the resource type to send the data to be transmitted may include the following execution steps:

[0112] Step S2221: When the resource type is a four-step random access process resource, the four-step random access process resource is used to send the data to be transmitted.

[0113] When the resource type for small data transmission indicated in the RRC Release message is a 4-stop RACH resource, the UE does not need to select different RACH types based on signal quality, that is, the UE does not need to determine whether the current Reference Signal Received Power (RSRP) meets the conditions for selecting 4-step RACH resources, but directly selects 4-step RACH resources to transmit the small data to be transmitted. When the UE initiates a 4-step RACH process to transmit small data, it needs to select a preamble from a specific preamble group to indicate the amount of data to be transmitted.

[0114] Optionally, in step S222, using the resource corresponding to the resource type to send the data to be transmitted may include the following execution steps:

[0115] Step S2222: When the resource type is a two-step random access process resource, the two-step random access process resource is used to send the data to be transmitted.

[0116] When the resource type for small data transmission indicated in the RRC Release message is 2-step RACH resource, the UE directly selects the 2-step RACH resource to transmit the small data to be transmitted. When the UE initiates the 2-step RACH process to transmit small data, it needs to select the corresponding MSGA resource so that the data block size supported by its PUSCH resource is greater than or equal to the amount of data to be transmitted.

[0117] Optionally, in step S222, using the resource corresponding to the resource type to send the data to be transmitted may include the following execution steps:

[0118] Step S2223, when the resource type is a two-step random access process resource, if the signal quality meets the use conditions of the two-step random access process resource, the two-step random access process resource is used to send the data to be transmitted; if the signal quality does not meet the use conditions of the two-step random access process resource, the four-step random access process resource is used to send the data to be transmitted; if the size of the data to be transmitted exceeds the data size supported by the four-step random access process resource. In other words, if the amount of data to be transmitted exceeds the maximum threshold for RRC Inactive state data transmission supported by the cell, the radio resource control recovery process is initiated, and the data to be transmitted is sent again after the user equipment recovers from the inactive state to the connected state.

[0119] When the resource type for small data transmission indicated in the RRC Release message is a 2-step RACH resource, the UE can determine whether the current RSRP meets the use conditions of the 2-step RACH resource. If the use conditions of the 2-step RACH resource are met, the UE uses the 2-step RACH resource to transmit small data. If the use conditions of the 2-step RACH resource are not met, the UE uses the 4-step RACH resource to transmit small data. If the size of the small data exceeds the data size supported by the 4-step RACH resource. In other words, if the amount of data to be transmitted exceeds the maximum threshold for RRC Inactive state data transmission supported by the cell, the UE initiates the RRC Resume process and initiates data transmission after recovering to the connected state.

[0120] Alternatively, if the conditions for using 2-step RACH resources are not met, the UE directly initiates the RRC Resume procedure and initiates data transmission after recovering to the connected state.

[0121] Optionally, in step S222, using the resource corresponding to the resource type to send the data to be transmitted may include the following execution steps:

[0122] Step S2224: When the resource type is a configuration authorization type resource, the configuration authorization type resource is used to send the data to be transmitted.

[0123] When the RRC Release message indicates that the resource type used for small data transmission is CG Type1, the UE selects CGTyep1 resources to transmit small data.

[0124] Optionally, in step S22, sending the data to be transmitted to the network side device based on the resource configuration message may include the following execution steps:

[0125] Step S223, entering an inactive state of radio resource control based on the first indication information and determining a transmission resource corresponding to each logical channel in a plurality of logical channels;

[0126] Step S224: in an inactive state, using transmission resources to send data to be transmitted.

[0127] When the network side device distinguishes the small data transmission resources corresponding to different logical channels by configuring different logical channels, the UE receives a configuration message from the network side device. The configuration message can configure different logical channels of the UE so that the corresponding data to be transmitted of different logical channels can be transmitted on different resources when the UE enters the RRC INACTIVE state.

[0128] The data to be transmitted on a specific logical channel can be restricted to be transmitted on specific resources, for example, through 4-step RACH resources or through 2-step RACH resources, or can be restricted to be transmitted on more than one resource, for example, 4-step RACH or 2-step RACH resources can be selected for transmission, or there can be no restriction, that is, the data to be transmitted on the logical channel can be transmitted on any configured resource. In this case, if there are multiple resources, the UE can select a specific resource to transmit the data of the logical channel based on a preset rule.

[0129] When the network side device distinguishes the CG Type 1 resources corresponding to different logical channels by configuring different logical channels, the network side device can configure the data of a specific logical channel to be transmitted on the CG Type 1 resource. That is, when the network side device configures one or more CG Type 1 resources for the UE, the network side device can configure a specific logical channel to be limited to be transmitted on one or more CG Type 1 resources.

[0130] Therefore, the resource configuration message sent by the network side device can use resources that are more suitable for the transmission of small data of different logical channels for small data of the logical channels, thereby improving resource utilization.

[0131] Optionally, in step S224, using the transmission resource to send the data to be transmitted may include the following execution steps:

[0132] Step S2241: When a first logical channel among multiple logical channels is configured with a single limited type resource, the single limited type resource is used to send data to be transmitted.

[0133] In an optional example, it is assumed that the UE has three different logical channel configurations. Table 1 shows the three different logical channel configurations, as shown in Table 1:

[0134] Logical channel #1 Only small data can be transmitted through 4-step RACH resources Logical channel #2 Only small data can be transmitted through 2-step RACH resources Logical Channel #3 Small data can only be transmitted through 4-step RACH resources or 2-step RACH resources Logical Channel #4 No restrictions

[0135] The first logical channel may be logical channel #1 or logical channel #2.

[0136] When a UE in the RRC INACTIVE state has data to be transmitted on logical channel #1, according to the above logical channel configuration, the data to be transmitted is restricted to be transmitted only through 4-step RACH resources. The UE will trigger the 4-step RACH process, and indicate to the network side device that there is data to be transmitted through the configured preamble or RO resources. The network side device can schedule a relatively large UL grant through RAR to enable the UE to transmit small data.

[0137] When a UE in the RRC INACTIVE state has data to be transmitted on logical channel #2, according to the above logical channel configuration, the data to be transmitted is restricted to be transmitted only through 2-step RACH resources, then the UE will trigger the 2-step RACH process and select the MSGA resource matching the small data size to transmit the small data.

[0138] In another optional example, it is assumed that the network side device configures CG Type 1 resources supporting three different transport block sizes (Transport Block Size, referred to as TBS) for the UE, and also configures which CG Type 1 resources different logical channels can use for data transmission. Table 2 is the resource transmission configuration of different logical channels, as shown in Table 2:

[0139] Logical channel #1 Can only be transmitted via CG Tyep1#1 Logical channel #2 Can only be transmitted via CG Tyep1#2 Logical Channel #3 Can only be transmitted via CG Tyep1#1 or CG Tyep1#2 Logical Channel #4 No restrictions

[0140] The first logical channel may be logical channel #1 or logical channel #2.

[0141] When a UE in RRC INACTIVE state has data to be transmitted on logical channel #1, according to the above logical channel configuration, the data to be transmitted can only be transmitted on the CG resource of CG Tyep1#1 (ie index=1), and the CGTyep1#1 resource corresponds to a TBS size.

[0142] When a UE in RRC INACTIVE state has data to be transmitted on logical channel #2, according to the above logical channel configuration, the data to be transmitted can only be transmitted on the CG resource of CG Tyep1#2 (ie index=2), and the CGTyep1#1 resource corresponds to a TBS size.

[0143] Optionally, in step S224, using the transmission resource to send the data to be transmitted may include the following execution steps:

[0144] Step S2242: When a second logical channel among the multiple logical channels is configured with multiple limited type resources, a transmission resource is selected from the multiple limited type resources, and the data to be transmitted is sent on the transmission resource.

[0145] In an optional example, as shown in Table 1, the second logical channel may be logical channel #3. When the UE in the RRCINACTIVE state has data to be transmitted on logical channel #3, according to the above logical channel configuration, the data to be transmitted is restricted to be transmitted only through 4-step RACH resources or 2-step RACH resources.

[0146] In another optional example, as shown in Table 2, the second logical channel may be logical channel #3. When the UE in the RRCINACTIVE state has data to be transmitted on logical channel #3, according to the above logical channel configuration, the data to be transmitted can only be transmitted on the CG resources of CG Tyep1#1 (ie, index=1) or CG Tyep1#2 (ie, index=2).

[0147] Optionally, in step S224, using the transmission resource to send the data to be transmitted may include the following execution steps:

[0148] Step S2243: When a third logical channel among the multiple logical channels is configured with a plurality of resources of any type, a transmission resource is selected from the plurality of resources of any type according to a preset rule, and the data to be transmitted is sent on the transmission resource.

[0149] In an optional example, as shown in Table 1, the third logical channel may be logical channel #4. When a UE in the RRCINACTIVE state has data to be transmitted on logical channel #4, according to the above logical channel configuration, the data to be transmitted has no resource type restrictions, and the UE may select corresponding resources according to preset rules, for example, selecting matching resources (2-step RACH resources or CG Type 1 resources) according to the size of the data to be transmitted. If there are no matching resources, the UE initiates a 4-step RACH process. The preset rule may be that the UE uses specific resources (for example, 4-step RACH resources) by default to transmit the small data to be transmitted.

[0150] In another optional example, as shown in Table 2, the third logical channel may be logical channel #4. When the UE in the RRCINACTIVE state has data to be transmitted on logical channel #4, according to the above logical channel configuration, the logical channel has no restrictions and can be transmitted on any CG Tyep1 resource as long as the TBS of the CG Tyep1 resource can meet the size of the data to be transmitted.

[0151] Optionally, in step S224, using the transmission resource to send the data to be transmitted may include the following execution steps:

[0152] Step S2244, when there is data to be transmitted on multiple logical channels at the same time, the specified type of resource is determined as the transmission resource, and the data to be transmitted is sent on the transmission resource; or, a wireless resource control recovery process is initiated, and the data to be transmitted is sent after the user equipment recovers from an inactive state to a connected state.

[0153] The above-mentioned specified type of resources can be 4-step RACH resources or default type resources. When there are multiple logical channels with data to be transmitted at the same time, the UE can select 4-step RACH resources to transmit the data to be transmitted on these logical channels, or formulate a default resource type based on the network configuration to transmit the data to be transmitted on these logical channels, or directly initiate the RRC resume process and transmit data after recovering to the connected state.

[0154] In this embodiment, another data transmission method running on the above network side device is also provided. Figure 3 is a flow chart of another data transmission method according to one embodiment of the present invention. Figure 3 As shown, the method comprises the following steps:

[0155] Step S30, generating a resource configuration message, wherein the information carried in the resource configuration message includes: first indication information, the first indication information is used to indicate a transmission mode of data to be transmitted on the user equipment, and the data to be transmitted is data bound to a logical channel or a user plane bearer;

[0156] Step S32: Send a resource configuration message to the user equipment.

[0157] Through the above steps, a resource configuration message is generated, and the information carried in the resource configuration message includes first indication information, and the first indication information is used to indicate the transmission method of the data to be transmitted on the user equipment, and the data to be transmitted is a method of data bound to the logical channel or the user plane bearer. By sending the resource configuration message to the user equipment, the purpose of UE transmitting small data according to the indication information issued by the network side device is achieved, thereby achieving the technical effect of effectively improving resource utilization, and further solving the technical problem of how to transmit small data when the UE has small data to be transmitted if the network side device configures multiple transmission resources for the UE at the same time in the related technology.

[0158] Optionally, the first indication information is used to instruct the user equipment to enter an inactive state of radio resource control and to indicate a resource type used for data to be transmitted.

[0159] Optionally, the resource configuration message includes one of the following:

[0160] (1) Radio resource control release message;

[0161] (2) System messages;

[0162] (3) Radio resource control reconfiguration message in connected state.

[0163] That is, the resource configuration message may be an RRC Release message, a system message, or an RRC reconfiguration message in a connected state. Therefore, the present invention does not specifically limit the type of message carrying the first indication information.

[0164] Optionally, the resource type may include but is not limited to one of the following:

[0165] (1) 4-step RACH resources;

[0166] (2) 2-step RACH resources;

[0167] (3)CG TYPE1 resources.

[0168] Optionally, the first indication information is used to instruct the user equipment to enter an inactive state of radio resource control and to indicate a transmission resource corresponding to each logical channel in multiple logical channels.

[0169] When the network side device distinguishes the small data transmission resources corresponding to different logical channels by configuring different logical channels, the UE receives a configuration message from the network side device. The configuration message can configure different logical channels of the UE so that the corresponding data to be transmitted of different logical channels can be transmitted on different resources when the UE enters the RRC INACTIVE state.

[0170] Optionally, the transmission resource corresponding to each logical channel in the multiple logical channels includes one of the following:

[0171] (1) a resource of a single defined type configured for a first logical channel among multiple logical channels;

[0172] (2) multiple types of limited resources configured for a second logical channel among the multiple logical channels;

[0173] (3) A plurality of arbitrary types of resources configured for a third logical channel among the plurality of logical channels.

[0174] The data to be transmitted on a specific logical channel can be restricted to be transmitted on specific resources, for example, through 4-step RACH resources or through 2-step RACH resources, or can be restricted to be transmitted on more than one resource, for example, 4-step RACH or 2-step RACH resources can be selected for transmission, or there can be no restriction, that is, the data to be transmitted on the logical channel can be transmitted on any configured resource. In this case, if there are multiple resources, the UE can select a specific resource to transmit the data of the logical channel based on a preset rule.

[0175] When the network side device distinguishes the CG Type 1 resources corresponding to different logical channels by configuring different logical channels, the network side device can configure the data of a specific logical channel to be transmitted on the CG Type 1 resource. That is, when the network side device configures one or more CG Type 1 resources for the UE, the network side device can configure a specific logical channel to be limited to be transmitted on one or more CG Type 1 resources.

[0176] Optionally, the above method may further include the following execution steps:

[0177] Step S34: obtaining second indication information sent by the user equipment, wherein the second indication information is used to indicate that there is data to be transmitted on the user equipment.

[0178] In an optional embodiment, when the UE transmits small data by initiating a 4-step RACH process, the UE can indicate to the network side device that the UE has small data during the data transmission process through a specific preamble (the preamble belongs to a preconfigured preamble group, which is equivalent to the above-mentioned second indication information).
