Fig. 1 shows a block diagram of a communication system provided in an exemplary embodiment of the present application, which may include: access network 12 and terminal equipment 14.
Access network 12 includes a number of network devices 120 therein. The network device 120 may be a base station, which is a means deployed in an access network to provide wireless communication functionality for terminals. The base stations may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems employing different radio access technologies, the names of base station capable devices may vary, for example in LTE systems, called enodebs or enbs; in a 5G NR-U system, it is called gNodeB or gNB. As communication technology evolves, the description of "base station" may change. For convenience in the embodiments of the present application, the above-mentioned devices for providing the terminal device 14 with the wireless communication function are collectively referred to as a network device.
The terminal device 14 may include various handheld devices, vehicle mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, as well as various forms of user equipment, mobile Stations (MSs), terminals (terminal devices), etc. For convenience of description, the above-mentioned devices are collectively referred to as a terminal. The network device 120 and the terminal device 14 communicate with each other via some air interface technology, e.g. Uu interface. Optionally, the terminal device is in an rrc_inactive state.
The technical solution of the embodiment of the application can be applied to various communication systems, for example: global system for mobile communications (Global System of Mobile Communication, GSM), code division multiple access (Code Division Multiple Access, CDMA) system, wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA) system, general packet Radio service (General Packet Radio Service, GPRS), long term evolution (Long Term Evolution, LTE) system, LTE frequency division duplex (Frequency Division Duplex, FDD) system, LTE time division duplex (Time Division Duplex, TDD) system, long term evolution advanced (Advanced Long Term Evolution, LTE-a) system, new Radio (NR) system, evolution system of NR system, LTE (LTE-based access to Unlicensed spectrum, LTE-U) system on unlicensed frequency band, NR-U system, universal mobile telecommunication system (Universal Mobile Telecommunication System, UMTS), worldwide interoperability for microwave access (Worldwide Interoperability for Microwave Access, wiMAX) communication system, wireless local area network (Wireless Local Area Networks, WLAN), wireless fidelity (Wireless Fidelity, wiFi), next generation communication system or other communication system, etc.
Generally, the number of connections supported by the conventional communication system is limited and easy to implement, however, as the communication technology advances, the mobile communication system will support not only conventional communication but also, for example, device-to-Device (D2D) communication, machine-to-machine (Machine to Machine, M2M) communication, machine type communication (Machine Type Communication, MTC), inter-vehicle (Vehicle to Vehicle, V2V) communication, and internet of vehicles (Vehicle to Everything, V2X) systems, etc. The embodiments of the present application may also be applied to these communication systems.
Fig. 2 shows a flowchart of a data transmission method according to an exemplary embodiment of the present application. The method may be applied in a terminal device as shown in fig. 1, where the terminal device resides in a first cell.
Wherein the terminal device residing in the first cell is in an rrc_inactive state, and may perform an INACTIVE data transfer (Inactive Data Transmission, IDT) procedure. The IDT procedure is a procedure in which the terminal device performs data transmission in an RRC INACTIVE state (i.e., rrc_inactive state). The IDT procedure does not require the establishment of RRC connection between the terminal device and the network device. The embodiment of the present application does not limit a specific process of the IDT flow.
For the terminal equipment in the rrc_inactive state, if the data transmission is performed after the RRC connection with the network equipment is restored only through the connection establishment restoration procedure, the terminal equipment needs to return to the rrc_inactive state after the data transmission is completed. For terminal devices with small data size and low transmission frequency, power consumption is large. Through IDT flow, the conversion of connection state is avoided, and power consumption can be reduced.
The method comprises step 210 or step 220:
in step 210, in the case that the first cell is not a configuration cell, the IDT procedure is not allowed to be triggered.
The configuration cell is a cell where the terminal equipment resides when acquiring logic channel configuration information, and the logic channel configuration information is used for configuring a logic channel supporting the trigger IDT flow.
Alternatively, the logical channel configuration information is information configured to the terminal device by the network device when the terminal device is in an RRC CONNECTED state (i.e., rrc_connected state). Because the service quality (Qualityof Service, qoS) requirements of the services corresponding to different data are different, the services are mapped to different logic channels, and the network device can configure whether the Logic Channel (LCH) supports the IDT triggering process through the logic Channel configuration information.
Exemplary logical channel configuration information includes: the logical channels supporting the trigger IDT procedure are logical channel #1 and logical channel #2.
Optionally, the first cell being not a configured cell means: when in a connection state, the terminal equipment does not reside in the first cell; or when in a connection state, although the terminal equipment resides in the first cell, the corresponding logic channel configuration information is not acquired.
That is, in the case where the terminal device resides in the first cell and the terminal device is in the rrc_inactive state, the first cell does not correspond to valid logical channel configuration information. The terminal device residing in the first cell is not allowed to trigger the IDT procedure for data transmission.
Step 220, in the case that the first cell is not a configured cell, determining whether to allow the IDT procedure to be triggered according to the trigger condition corresponding to the first cell.
The configuration cell is a cell where the terminal equipment resides when acquiring logic channel configuration information, and the logic channel configuration information is used for configuring a logic channel supporting the trigger IDT flow.
The first cell corresponds to a trigger condition, and the terminal device can determine whether to trigger the IDT flow in the first cell for data transmission according to the trigger condition when the first cell is not a configuration cell.
Optionally, the first cell being not a configured cell means: when in a connection state, the terminal equipment does not reside in the first cell; or when in a connection state, although the terminal equipment resides in the first cell, the corresponding logic channel configuration information is not acquired.
Optionally, the first cell may have one or more trigger conditions corresponding to the first cell, and the terminal device may determine whether to trigger the IDT procedure according to at least one trigger condition in the first cell.
In summary, in the method provided in this embodiment, in the case of being in the inactive state, the terminal device may trigger the IDT procedure according to the configuration of the logic channel configuration information, and when the first cell in which the terminal device resides does not acquire the valid logic channel configuration information and is not a configured cell, the terminal device may not allow the IDT procedure to be triggered, or determine whether to allow the IDT procedure to be triggered according to the triggering condition, so as to provide a method for determining whether to allow the IDT procedure to be triggered.
In an alternative embodiment based on fig. 2, the first cell is the cell where the terminal device resides after a cell reselection has occurred.
Cell reselection (cell reselection) refers to a process that a terminal device selects a suitable cell to provide a service signal through measurement. Before the terminal equipment reselects the cell, the resident cell is a source cell; after performing the cell, the camping cell (i.e., the first cell) is the target cell.
Optionally, after the cell reselection occurs, the terminal device moves to the first cell, and the terminal device detects the first cell, and detects whether the first cell is a configuration cell.
In one possible scenario, the first cell is a configuration cell. That is, when the terminal device is in a connected state and camps on the first cell, the logical channel configuration information is once acquired. And after the cell reselection occurs and the terminal equipment moves to the first cell, triggering IDT transmission by using logic channel configuration information corresponding to the first cell.
In another possible scenario, the first cell is not a configured cell. That is, after the cell reselection occurs and the first cell is not a configured cell, the terminal device may determine whether the IDT procedure can be triggered in the new cell through any one of the two ways provided in the above embodiment.
Mode 1: triggering IDT flows is not allowed.
Mode 2: and determining whether to allow triggering of the IDT flow according to the triggering condition corresponding to the first cell.
The following is a further explanation of both of the above modes.
Mode 1: in case the first cell is not a configuration cell, triggering IDT flow is not allowed.
In the embodiment corresponding to the mode 1, the logic channel configuration is used as one of the necessary conditions for triggering the IDT flow, and when the terminal device cannot acquire the effective logic channel configuration, the IDT flow cannot be triggered, so that the terminal device is prevented from occupying the IDT resource of the current cell when the terminal device does not have the logic channel configuration of the current cell.
The source cell is a cell a, and the first cell in which the terminal device resides after cell reselection is a cell B. Reference is made in connection with the following examples:
1) The terminal equipment in the connection state obtains the logic channel configuration (namely logic channel configuration information) which can trigger the IDT flow in the cell A (source cell) through the special signaling. Such as: the logical channels that trigger IDT flow are logical channel #1 and logical channel #2.
The embodiment of the application does not limit the specific expression form of the dedicated signaling carrying the logic channel configuration information.
2) After the terminal device enters the rrc_inactive state, the terminal device is still in cell a. When data arrives, the terminal equipment determines whether the IDT flow can be triggered according to whether the current arriving data belongs to a logic channel capable of triggering the IDT flow.
Such as: the data to be transmitted comes from the logic channel #1, the logic channel #2, or the logic channel # 1+logic channel #2, and other conditions for triggering the IDT flow are satisfied, and the terminal device triggers the IDT flow.
3) After the terminal equipment enters the rrc_inactive state, the terminal equipment moves to the cell B, and since the terminal equipment cannot acquire the logic channel configuration (i.e., logic channel configuration information) of the cell B for triggering the IDT, the cell B is not a configuration cell, and therefore the terminal equipment cannot trigger the IDT flow in the cell B.
Mode 2: and under the condition that the first cell is not the configuration cell, determining whether to allow triggering of the IDT flow according to the triggering condition corresponding to the first cell.
Referring to fig. 3 in combination, fig. 3 shows a flowchart of a data transmission method according to an exemplary embodiment of the present application. The method may be applied in a terminal device as shown in fig. 1, where the terminal device resides in a first cell. The method comprises the following steps:
in step 310, in the case that the first cell is not a configured cell, the terminal device determines whether to allow the IDT procedure to be triggered according to at least one of the first trigger condition and the second trigger condition.
The first trigger condition is determined according to logic channel configuration information corresponding to a configuration cell in the neighboring candidate cell under the condition that the neighboring candidate cell comprises the configuration cell; the neighboring candidate cell is a neighboring cell of the first cell, and the terminal device where the first cell supports residence adopts logic channel configuration information corresponding to the neighboring candidate cell.
The first cell corresponds to a plurality of adjacent cells (or called adjacent cells), and the adjacent cells are cells which are overlapped with the signal coverage of the first cell and are provided with a switching relation. Wherein the neighboring candidate cells are all or part of neighboring cells corresponding to the first cell.
Illustratively, the neighbor cell of the first cell includes: cell #1, cell #2, and cell #3, wherein cell #2 and cell #3 are neighbor candidate cells of the first cell. The terminal equipment supporting residence in the first cell adopts the logic channel configuration information corresponding to the cell #2 or the cell #3, and the terminal equipment not supporting residence in the first cell adopts the logic channel configuration information corresponding to the cell # 1.
Optionally, the neighboring candidate cell corresponding to the first cell is predefined; or, the neighboring candidate cell corresponding to the first cell is indicated by the broadcast message of the first cell, and the terminal device determines the neighboring candidate cell corresponding to the first cell according to the broadcast message of the first cell.
In one possible scenario, the neighboring candidate cell to which the first cell corresponds does not include a configured cell. Such as: the neighboring candidate cells of the first cell include: cell #1 and cell #2, and cell #1 and cell #2 are not configured cells, and there is no logic channel configuration information, the terminal device cannot determine the first trigger condition, and cannot determine whether to allow to trigger the IDT procedure according to the first trigger condition.
In another possible scenario, the neighboring candidate cell to which the first cell corresponds includes a configured cell. Such as: the neighboring candidate cells of the first cell include: cell #1 and cell #2.
If the cell #1 is a configuration cell, the terminal device determines a first trigger condition according to the logic channel configuration information corresponding to the cell #1, and determines whether to allow triggering of the IDT procedure according to the first trigger condition.
If both cell #1 and cell #2 are configured cells, the terminal device determines a first trigger condition according to the logic channel configuration information corresponding to cell #1 (or the logic channel configuration information corresponding to cell # 2), and determines whether to allow triggering of the IDT procedure according to the first trigger condition. The terminal device may randomly select one of the logic channel configuration information corresponding to the cells belonging to the configured cell, or may select the logic channel configuration information corresponding to one of the cells according to a certain rule, which is not limited in the embodiment of the present application.
Wherein the second trigger condition is a condition different from the first trigger condition.
Optionally, the terminal device determines what trigger condition to use according to the indication of the indication information. Referring to fig. 4 in combination, before step 310, step 320 is further included:
step 320: and acquiring indication information.
Wherein, the indication information includes: at least one of the first indication information and the second indication information. The first indication information is used for indicating adjacent candidate cells corresponding to the first cell, and the second indication information is used for indicating whether the terminal equipment supports triggering the IDT flow based on the second trigger condition.
Optionally, the indication information is carried in a broadcast message of the first cell.
That is, the terminal device will determine whether to trigger the IDT procedure according to the indication of the indication information, using the corresponding trigger condition.
1) The indication information comprises: first indication information; or, the indication information includes: the first indication information and the second indication information indicate that the terminal equipment does not support triggering the IDT flow based on the second triggering condition; step 310 is alternatively implemented as step 311-1 or step 311-2:
step 311-1: in the case that the first cell is not a configuration cell and the neighboring candidate cell of the first cell includes a configuration cell, it is determined whether to allow triggering of the IDT procedure according to the first trigger condition.
Step 311-2: in the case where the first cell is not a configuration cell and the neighboring candidate cell of the first cell does not include a configuration cell, triggering of IDT flow is not allowed.
The indication information includes first indication information indicating neighboring candidate cells of the first cell. When the indication information does not include the second indication information or the second indication information explicitly indicates that the terminal device cannot trigger the IDT flow based on the second trigger condition, it means that the terminal device cannot trigger the IDT flow based on other conditions than the first trigger condition.
Optionally, the terminal device determines whether a configuration cell exists in the neighboring candidate cell of the first cell, and if the configuration cell exists in the neighboring candidate cell, determines a first trigger condition according to logic channel configuration information corresponding to the configuration cell, and determines whether to allow triggering of the IDT procedure according to the first trigger condition. In the case where there is no configured cell in the neighboring candidate cell, since the terminal device cannot trigger the IDT flow based on the other conditions than the first trigger condition, the IDT flow is not allowed to be triggered.
2) The indication information comprises: the first indication information and the second indication information indicate that the terminal equipment supports triggering the IDT flow based on the second trigger condition; step 310 is alternatively implemented as step 312-1 or step 312-2:
Step 312-1: in the case that the first cell is not a configuration cell and the neighboring candidate cell of the first cell includes a configuration cell, it is determined whether to allow triggering of the IDT procedure according to the first trigger condition.
Step 312-2: in the case that the first cell is not a configuration cell and the neighboring candidate cell of the first cell does not include a configuration cell, determining whether to allow triggering of the IDT procedure according to the second trigger condition.
The indication information includes first indication information indicating neighboring candidate cells of the first cell. The indication information further includes second indication information, and when the second indication information explicitly indicates that the terminal device can trigger the IDT flow based on the second trigger condition, it means that the terminal device can trigger the IDT flow based on other conditions than the first trigger condition.
Optionally, the terminal device determines whether a configuration cell exists in the neighboring candidate cell of the first cell, and if the configuration cell exists in the neighboring candidate cell, determines a first trigger condition according to logic channel configuration information corresponding to the configuration cell, and determines whether to allow triggering of the IDT procedure according to the first trigger condition. And under the condition that no configuration cell exists in the adjacent candidate cells, the terminal equipment determines whether to allow the IDT flow to be triggered according to the second trigger condition.
3) The indication information comprises: the second indication information indicates that the terminal equipment supports triggering the IDT flow based on the second trigger condition; step 310 is alternatively implemented as step 313:
step 313: in the case that the first cell is not a configuration cell, it is determined whether to allow the IDT flow to be triggered according to the second trigger condition.
When the indication information only includes the second indication information and the second indication information explicitly indicates that the terminal device can trigger the IDT flow based on the second trigger condition, the terminal device can trigger the IDT flow based on other conditions than the first trigger condition.
Optionally, the terminal device determines whether to allow triggering of the IDT procedure directly according to the second trigger condition.
Optionally, in the above step 311-1 and step 312-1, the terminal device determines whether to allow the process of triggering the IDT procedure according to the first triggering condition, including: determining a target logical channel according to the logical channel configuration information corresponding to the configuration cell, wherein the target logical channel is a logical channel supporting the trigger IDT flow; triggering IDT flow under condition that data to be transmitted by terminal equipment comes from target logic channel; and under the condition that the data to be transmitted by the terminal equipment is not from the target logic channel, the IDT flow is not triggered.
Illustratively, the target logical channel includes: logical channel #1 and logical channel #2, logical channel #1 and logical channel #2 are logical channels that can trigger IDT flow. If the data to be transmitted by the terminal device comes from the logical channel #1, the logical channel #2, or the logical channel # 1+the logical channel #2, the IDT procedure is triggered. If the data to be transmitted by the terminal device comes from the logical channel #4, the IDT flow is not triggered.
Optionally, in the above step 312-2 and step 313, the terminal device determines whether to allow the IDT procedure to be triggered according to the second trigger condition, including: allowing to trigger IDT flow under the condition that the size of data to be transmitted by the terminal equipment is smaller than a threshold value; and under the condition that the size of data to be transmitted by the terminal equipment is not smaller than the threshold value, triggering the IDT flow is not allowed.
The threshold is a maximum Transport Block Size (TBS) corresponding to data to be transmitted.
Optionally, the threshold is carried in a broadcast message of the first cell. After receiving the threshold, the terminal device can determine the second trigger condition.
The threshold is, for example, 2000bits. The data volume of the data to be transmitted is 1800bits, the data size is less than the threshold value, and the terminal equipment triggers the IDT flow. The data volume of the data to be transmitted is 2500bits, the data size is not satisfied with the threshold value, and the terminal equipment does not trigger the IDT flow.
It will be appreciated that the second trigger condition may be other forms of trigger conditions, which are not limited in this embodiment of the present application.
In the embodiment corresponding to the mode 2, the terminal device may be assisted to determine the effective logic channel configuration through the first indication information in the indication information, or may determine whether to trigger the IDT procedure according to other triggering conditions through the second indication information in the indication information.
The source cell is a cell a, and the first cell in which the terminal device resides after cell reselection is a cell B. Reference is made in connection with the following examples:
1) The terminal equipment in the connection state obtains the logic channel configuration (namely logic channel configuration information) which can trigger the IDT flow in the cell A (source cell) through the special signaling. Such as: the logical channels that trigger IDT flow are logical channel #1 and logical channel #2.
The embodiment of the application does not limit the specific expression form of the dedicated signaling carrying the logic channel configuration information.
2) After the terminal device enters the rrc_inactive state, the terminal device is still in cell a. When data arrives, the terminal equipment determines whether the IDT flow can be triggered according to whether the current arriving data belongs to a logic channel capable of triggering the IDT flow.
Such as: the data to be transmitted comes from the logic channel #1, the logic channel #2, or the logic channel # 1+logic channel #2, and other conditions for triggering the IDT flow are satisfied, and the terminal device triggers the IDT flow.
3) After the terminal device enters the rrc_inactive state, the terminal device moves to the cell B, where the cell B carries indication information in a broadcast message, where the indication information is used to indicate which cells' logic channel configuration information may be used as a condition (i.e. a first trigger condition) for triggering the IDT procedure in the cell, and/or whether the terminal device is allowed to trigger the IDT procedure based on a condition other than the logic channel configuration information (i.e. a second trigger condition).
A) The terminal equipment determines, through the indication information, that the cell B does not allow the terminal equipment to take the logic channel configuration information of the cell a as one of conditions for triggering the IDT flow, and the cell B does not support the IDT flow triggered based on other conditions (i.e., the second triggering condition) except the logic channel configuration information (does not include the indication information or the indication information explicitly indicates that the IDT flow is not supported), so that the terminal equipment cannot trigger the IDT flow in the cell B.
B) The terminal equipment determines that the cell B allows the terminal equipment to take the logic channel configuration information of the cell A as one of conditions for triggering IDT flow according to the indication information.
