Patent Description:
The development of new-generation novel Internet applications such as Augmented Reality (AR)/Virtual Reality (VR) and vehicle-to-vehicle communication makes higher requirements on wireless communication technologies and urges the wireless communication technologies to be constantly evolved to meet the requirements of the applications. At present, a cellular mobile communication technology is in an evolution stage of a new-generation technology. An important characteristic of the new-generation technology is to support flexible configuration of multiple service types. Different service types have different requirements on a wireless communication technology. For example, a main requirement of an enhanced Mobile Broad Band (eMBB) service type focuses on the aspects of large bandwidth, high rate and the like, a main requirement of an Ultra Reliable Low Latency Communication (URLLC) service type focuses on the aspects of relatively high reliability and low delay, and a main requirement of a massive Machine Type Communication (mMTC) service type focuses on the aspect of large connection number. Therefore, a new-generation wireless communication system requires a flexible and configurable design to support transmission of multiple service types.

Under the development of service requirements, only using a licensed spectrum may not meet increasing service requirements, so deployment of a mobile network on an unlicensed spectrum is considered. There may be another system such as a Wireless Fidelity (WiFi) system on the unlicensed spectrum such as <NUM> spectrum and <NUM> spectrum. How to ensure fair resource sharing of different communication systems on an unlicensed spectrum needs to be researched.

<NPL>" relates to potential solutions and techniques related to NR-U frame structure. <NPL>" relates to physical layer procedures for NR unlicensed operation to efficiently utilize the large amounts of unlicensed spectrum. <NPL>" relates to considerations regarding the channel access mechanism for autonomous uplink.

For solving the problem in the related art, embodiments of the present disclosure provide an information transmission method and device, a base station and UE, which may improve flexibility in configuration of a data transmission starting position on an unlicensed spectrum, thereby improving an effective utilization rate of a resource of an unlicensed spectrum.

According to the invention, an information transmission method according to claim <NUM> is provided, which may be applied to a base station. Embodiments are set out in dependent claims <NUM> to <NUM>.

According to the invention, an information transmission method according to claim <NUM> is provided, which may be applied to UE. Embodiments are set out in dependent claims <NUM> to <NUM>.

According to the invention, an information transmission device according to claim <NUM> is provided, which may be arranged in a base station.

According to the invention, an information transmission device according to claim <NUM> is provided, which may be arranged in UE.

Execution subjects involved in the present disclosure include a base station and UE. The base station may be a base station, sub base station and the like with a massive antenna array. The UE may be a user terminal, a user node, a mobile terminal, a tablet computer or the like. In a specific implementation process, the base station and the UE are independent respectively, and also communicate with each other to implement the technical solutions provided in the present disclosure together.

The present invention provides an information transmission method, to enable a system device through data transmission starting positions, configured by a base station, on an unlicensed spectrum to timely transmit information by use of resources of the unlicensed spectrum after detecting an idle channel resource of the unlicensed spectrum, thereby effectively utilizing the resources of the unlicensed spectrum and improving the information transmission efficiency.

<FIG> is a flow chart showing an information transmission method according to an exemplary embodiment. The method is applied to a base station of a 5th-Generation (<NUM>) New Radio (NR) network, and includes the following operations.

In <NUM>, transmission configuration information of an unlicensed spectrum is determined, the transmission configuration information being used to indicate each data transmission starting position in a preset time window.

In the related art, a data transmission starting position, for example, symbol <NUM> or symbol <NUM> of a subframe, on an unlicensed spectrum in a License Assisted Access (LAA) mechanism is specified in a 4th-Generation (<NUM>) Long Term Evolution (LTE) system protocol. That is, in the related art, when an information sender detects an idle channel resource of the unlicensed spectrum, information transmission is performed through the unlicensed spectrum according to the data transmission starting position specified in the system protocol.

Unlike the related art, in the present invention, the base station may flexibly configure the data transmission starting positions on the unlicensed spectrum in the preset time window according to a preset rule. The preset time window may include one or more transmission units. In an <NUM> NR system, the transmission unit may be a subframe, a slot, a mini-slot, an Orthogonal Frequency Division Multiplexing (OFDM) symbol and the like.

In the present disclosure, the base station may determine specific transmission configuration information of the unlicensed spectrum according to device information of all UE or UE of a preset type that presently accesses the network, or, the base station determines corresponding transmission configuration information of the unlicensed spectrum for a UE that accesses the network.

That is, the transmission configuration information, determined by the base station, of the unlicensed spectrum may be applied to all UE or UE of a part of types that accesses the cell network, and may also be dedicated to specified UE.

In an embodiment of the present disclosure, the base station may determine the transmission configuration information of the unlicensed spectrum with reference to a channel condition of the unlicensed spectrum.

Referring to a flow chart showing another information transmission method according to an exemplary embodiment in <FIG>, the operation in <NUM> may include the following steps.

In <NUM>, a channel condition of the unlicensed spectrum is monitored.

The unlicensed spectrum such as <NUM> spectrum and <NUM> spectrum is available for various technologies such as Bluetooth (BT) and WiFi technologies, and consequently, an interference environment is usually complex. In the present disclosure, the base station, after detecting an idle channel resource of the unlicensed spectrum, may monitor channel quality information of the unlicensed spectrum by use of a related technology, to subsequently determine how to configure the data transmission starting positions according to the channel condition of the unlicensed spectrum.

For monitoring the channel condition of the unlicensed spectrum, for example, the base station may acquire channel quality information of a downlink channel of the unlicensed spectrum through reciprocity of uplink and downlink channels according to a measurement result of an uplink Sounding Reference Signal (SRS).

Or, the base station sends a downlink reference signal to a UE or multiple or all UE within a signal coverage in the unlicensed spectrum. Each UE measures the downlink reference signal and feeds back a measurement result to the base station, to enable the base station to determine the channel quality information of the unlicensed spectrum according to the measurement result of the downlink reference signal.

In <NUM>, the transmission configuration information of the unlicensed spectrum is determined according to the channel condition of the unlicensed spectrum.

In an embodiment of the present invention, the base station may determine a resource utilization condition of the unlicensed spectrum according to the channel quality information. When the channel of the unlicensed spectrum is relatively idle, the base station may configure fewer data transmission starting positions in the preset time window. Conversely, when the channel resource of the unlicensed spectrum is insufficient, the base station may configure more data transmission starting positions in the preset time window.

In another embodiment of the present disclosure, the base station may also configure the data transmission starting positions with reference to a frequency range of the idle channel of the unlicensed spectrum.

A specific implementation process is as follows: the base station may determine a subcarrier spacing supported on a corresponding working carrier according to the frequency range, for example, <NUM>,<NUM> to <NUM>,<NUM>, of the idle channel of the unlicensed spectrum. The subcarrier spacing is a difference between center frequencies of two adjacent subcarriers.

According to related knowledge, for an OFDM-based system, a size of the subcarrier spacing is inversely proportional to a time length of an OFDM symbol, namely if the subcarrier spacing is larger, the time length of the corresponding OFDM symbol is smaller. Correspondingly, more data transmission starting positions on the unlicensed spectrum may be configured within a preset time window.

Therefore, the base station configures the data transmission starting positions according to the following principle: the number of the data transmission starting positions configured in the preset time window is directly proportional to the subcarrier spacing.

That is, when the base station supports a relatively large subcarrier spacing on the corresponding working carrier, more data transmission starting positions may be configured in the preset time window.

Conversely, when the base station supports a relatively small subcarrier spacing on the corresponding working carrier, fewer data transmission starting positions may be configured in the preset time window to improve the flexibility in access by the information sender to the channel of the unlicensed spectrum. The information sender may be the base station, and may also be UE.

In the present disclosure, the base station determines the transmission configuration information by use of the following at least two modes.

A first implementation mode: the base station independently determines the number of data transmission starting positions required to be set in the preset time window and a position of each data transmission starting position in the preset time window according to a preset rule, thereby determining the transmission configuration information.

Referring to a flow chart showing another information transmission method according to an exemplary embodiment in <FIG>, the operation in <NUM> includes the following steps.

In <NUM>, the number of the data transmission starting positions in the preset time window is determined.

According to the invention the base station independently determines the number of data transmission starting positions required to be set in a preset time window on the unlicensed spectrum according to different application scenarios. For example, the base station may configure more data transmission starting positions in the preset time window according to a flexibility requirement of the system.

If the number of the data transmission starting positions is represented by N, in the present disclosure, N may be a positive integer more than or equal to <NUM>. For example, the preset time window is a subframe, and the subframe includes <NUM> symbols. In such case, N may be any integer more than or equal to <NUM> and less than or equal to <NUM>.

In <NUM>, each data transmission starting position is configured in the preset time window according to the number of the data transmission starting positions.

For example, the preset time window is a subframe. If the number, determined in <NUM>, of the data transmission starting positions is <NUM>, the base station may configure each data transmission starting position in the preset time window according to a preset rule. Exemplarily, the base station may set symbols <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM> and <NUM> of the subframe as possible data transmission starting positions <NUM> according to a uniform distribution principle respectively, as shown in <FIG>.

In another embodiment of the present disclosure, the base station may also configure each data transmission starting position on the unlicensed spectrum in the preset time window with reference to another factor. As shown in <FIG>, the base station may set symbols <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM> and <NUM> as the data transmission starting positions <NUM> on the unlicensed spectrum respectively, namely first four symbols in a first slot and first three symbols in a second slot are configured as the data transmission starting positions on the unlicensed spectrum.

In <NUM>, the transmission configuration information of the unlicensed spectrum is determined according to the configuration information of the data transmission starting positions in the preset time window.

The transmission configuration information is generated according to a specific configuration of the data transmission starting positions on the unlicensed spectrum by the base station in the preset time window, to indicate specific positions where the UE may transmit information through the resource of the unlicensed spectrum in the preset time window.

Corresponding to <FIG>, the transmission configuration information, determined by the base station, of the unlicensed spectrum is {<NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>}. Similarly, corresponding to <FIG>, the transmission configuration information, determined by the base station, of the unlicensed spectrum is {<NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>}.

A second implementation mode: the base station determines the transmission configuration information according to a preset transmission configuration list.

In <NUM>, a preset transmission configuration list is queried according to preset reference information to determine target configuration information of the data transmission starting positions.

In the present disclosure, the system may specify some preset types of configuration information for the transmission starting positions on the unlicensed spectrum. The base station may determine to use one piece of configuration information according to requirements of different application scenarios. The preset reference information is a reference for the base station to determine the target configuration information according to a practical application scenario, and may include at least one of the following information: device information such as a device type of the UE, the channel condition of the unlicensed spectrum, the subcarrier spacing supported by the base station on the unlicensed spectrum or other information.

The base station queries the preset transmission configuration list according to the preset reference information to determine the target configuration information of the data transmission starting positions. The preset transmission configuration information list includes a correspondence between preset reference information and configuration information of preset data transmission starting positions.

There is made such a hypothesis that the preset transmission configuration list includes three pieces of configuration information, exemplarily, as shown in Table <NUM>.

In the embodiment of the present disclosure, the base station may select one configuration information of the data transmission positions from Table <NUM> as the target configuration information, such as {<NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>}, according to the preset reference information. In an embodiment of the present disclosure, the base station may determine the transmission configuration information of the unlicensed spectrum according to the channel condition of the unlicensed spectrum after the idle channel of the unlicensed spectrum is detected.

In an embodiment, there is made such a hypothesis that the preset reference information includes channel quality information of the idle channel of the unlicensed spectrum. The channel quality information of the idle channel of the unlicensed spectrum is configured to represent the channel condition of the unlicensed spectrum, and for example, may be a Channel Quality Indication (CQI) and other information.

For example, the preset reference information is a CQI level of the channel of the unlicensed spectrum. In such case, the preset transmission configuration list may include a correspondence between a CQI and configuration information of data transmission starting positions, exemplarily, as shown in Table <NUM>.

According to related knowledge, a CQI level with a high value represents that the channel has good channel quality, and conversely, a CQI level with a low value represents relatively poor channel quality.

The base station, after determining the CQI level, such as <NUM>, of the channel of the unlicensed spectrum, may query Table <NUM> to determine the target configuration information of the data transmission starting positions, i.e., {<NUM>, <NUM>, <NUM>, <NUM>}.

In another embodiment of the present disclosure, if the preset reference information includes the subcarrier spacing supported by the base station on the unlicensed working carrier, the preset transmission configuration list includes a correspondence between a subcarrier spacing and configuration information of data transmission starting positions, exemplarily, as shown in Table <NUM>.

If the subcarrier spacing supported by the base station on the unlicensed spectrum is <NUM>, it is obtained by querying Table <NUM> that the corresponding target configuration information is {<NUM>, <NUM>, <NUM>, <NUM>}.

In <NUM>, the transmission configuration information of the unlicensed spectrum is determined according to the target configuration information.

In an embodiment of the present disclosure, the base station may directly determine the target configuration information as the transmission configuration information to be sent to the UE.

That is, the transmission configuration information directly includes the configuration information of the data transmission starting positions in the preset time window, such as {<NUM>, <NUM>, <NUM>, <NUM>}.

In another embodiment of the present disclosure, referring to a flow chart showing another information transmission method according to an exemplary embodiment in <FIG>, the operation in <NUM> may include the following steps.

In <NUM>, a preset index list is queried according to the target configuration information to determine a target index corresponding to the target configuration information, the preset index list including a correspondence between a preset index and configuration information of data transmission starting positions.

In an embodiment of the present disclosure, for the condition that the system predetermines the preset transmission configuration list, the system may also predetermine the preset index list. The preset index list includes the correspondence between the preset index and configuration information of the preset data transmission starting positions, exemplarily, as shown in Table <NUM>.

If the target configuration information, determined by the base station, of the data transmission starting positions is {<NUM>, <NUM>, <NUM>, <NUM>}, the corresponding target index is determined to be <NUM> according to Table <NUM>.

In <NUM>, the transmission configuration information of the unlicensed spectrum is generated according to the target index.

The transmission configuration information of the unlicensed spectrum may only include the target index.

Correspondingly, the UE side also presets the preset index list, and after detecting the target index, may determine the corresponding configuration information of the data transmission starting positions according to the target index.

In <NUM>, the transmission configuration information is sent to UE.

In the present disclosure, the base station may send the transmission configuration information of the unlicensed spectrum to the UE through RRC signaling, MAC CE signaling, physical-layer downlink control signaling and the like, such that the UE may receive downlink information sent by the base station or transmit uplink information through the channel of the unlicensed spectrum based on the transmission configuration information.

In the present disclosure, the base station may send the transmission configuration information to the UE through the resource of the unlicensed spectrum, and may also send the transmission configuration information to the UE through the resource of the unlicensed spectrum after accessing the channel of the unlicensed spectrum.

In an embodiment, the transmission configuration information includes the target configuration information of the data transmission starting positions on the unlicensed spectrum or the target index corresponding to the target configuration.

In <NUM>, the transmission configuration information is loaded in target resource bits of preset signaling.

In the present disclosure, the system may predetermine to adopt a preset number of bits to bear the transmission configuration information of the unlicensed spectrum in the preset signaling.

For example, the transmission configuration information includes the target index. In such case, the number of the target resource bit is related to the number of table entries of the preset index list. For example, if the preset index list includes three table entries, two bits may be adopted to bear the transmission configuration information; and similarly, if the preset index list includes seven table entries, three bits may be adopted to bear the transmission configuration information. That is, the number n of the target resource bit should meet that (<NUM>n-<NUM>) is more than or equal to the number of the table entries of the preset index list.

Exemplarily, corresponding to Table <NUM>, the base station may adopt two bits of the preset signaling to bear the transmission configuration information. If the target index is <NUM>, the two bits are set to be <NUM>.

In an embodiment of the present disclosure, a configuration position of the target resource bit in the preset signaling may be predetermined by the system to be, for example, bit <NUM> and bit <NUM>. In the example, the base station may load the target index in the bit <NUM> and bit <NUM> of the preset signaling.

In another embodiment of the present disclosure, the configuration position of the target resource bit in the preset signaling may also be dynamically configured by the base station. In such case, the base station may send indication information of the target resource bit to the UE in advance, to enable the UE to determine a specific resource where the transmission configuration information of the unlicensed spectrum may be parsed in the preset signaling.

It is to be noted that, in an embodiment, the indication information of the target resource bit and the transmission configuration information may be loaded in the same signaling, and moreover, in a time domain, a resource bit for bearing the indication information of the target resource bit is before the resource bit for bearing the transmission configuration information, such that the UE, during information parsing, may obtain the indication information of the target resource bit by parsing at first and then parse the transmission configuration information from the target resource bit indicated by the indication information.

In <NUM>, the transmission configuration information is sent to the UE through the preset signaling. The preset signaling includes any one of:.

RRC signaling, MAC CE signaling and physical-layer downlink control signaling.

In <NUM>, a preset signal used for identifying the data transmission starting positions on the unlicensed spectrum is configured in a target time-frequency resource according to the transmission configuration information.

In the embodiment of the present disclosure, the base station, after determining the configuration information of the transmission starting positions on the unlicensed spectrum, may also notify it to the UE implicitly. For example, the preset signal used for identifying the data transmission starting positions on the unlicensed spectrum, for example, a pilot signal, is configured in the target time-frequency resource. Exemplarily, when the configuration information, determined by the base station, of the data transmission starting positions on the unlicensed spectrum is (<NUM>, <NUM>, <NUM>, <NUM>), referring to a schematic diagram of an information transmission scenario according to an exemplary embodiment in <FIG>, the base station may configure the preset signal <NUM> in symbols <NUM>, <NUM>, <NUM> and <NUM> of a subframe on the target time-frequency resource to represent the transmission configuration information.

In <NUM>, the transmission configuration information is sent to the UE through the target time-frequency resource bearing the preset signal.

In the above example, the base station may implicitly send the transmission configuration information (<NUM>, <NUM>, <NUM>, <NUM>) to the UE through the target time-frequency resource with the subframe shown in <FIG>.

In the embodiment of the present disclosure, the target time-frequency resource may be predetermined by the system and may also be dynamically configured by the base station. When the target time-frequency resource is dynamically configured by the base station, before the operation in <NUM>, the base station is further required to send configuration information of the target time-frequency resource to the UE, such that the UE determines a time-frequency range of the target time-frequency resource according to the configuration information of the target time-frequency resource and subsequently detects the preset signal in the time-frequency range to parse the transmission configuration information of the unlicensed spectrum.

In <NUM>, information transmission with the UE is performed using a channel of the unlicensed spectrum according to the transmission configuration information.

In the present disclosure, implementation of the operation in <NUM> may include two conditions.

A first condition: when there is data required to be sent, the base station detects whether the channel of the unlicensed spectrum is idle, and after detecting an idle channel of the unlicensed spectrum, performs information transmission from any starting position through the resource of the unlicensed spectrum according to the target configuration information of the data transmission starting positions. Correspondingly, the UE receives the downlink information sent by the base station in the channel of the unlicensed spectrum according to the transmission configuration information.

A second condition: when there is data required to be sent, the UE may also detect whether the channel of the unlicensed spectrum is idle, and after detecting an idle channel of the unlicensed spectrum, sends the uplink information to the base station by use of the transmission configuration information through the channel of the unlicensed spectrum. The base station, after acquiring information of the idle channel, detected by the UE, of the unlicensed spectrum, may receive the uplink information sent by the UE through the channel of the unlicensed spectrum based on the target configuration information of the data transmission starting positions.

It can be seen that, by using the information transmission according to the present invention, the base station flexibly configures the data transmission starting positions in the preset time window according to the preset rule, generate the transmission configuration information of the unlicensed spectrum according to the determined target configuration information of the data transmission starting positions and send it to the UE, and then the UE performs information transmission with the base station based on the transmission configuration information of the unlicensed spectrum, so that it is ensured that an information sender may flexibly access the channel of the unlicensed spectrum after the idle channel resource of the unlicensed spectrum is detected, channel access opportunities are increased, a utilization rate of idle resources of the unlicensed spectrum is increased, and the data transmission efficiency is further improved.

Correspondingly, the present disclosure also provides an information transmission method, which is applied to UE. Referring to a flow chart showing an information transmission method according to an exemplary embodiment in <FIG>, the method may include the following operations.

In <NUM>, position reference information is acquired, the position reference information being used to determine a data transmission starting position on an unlicensed spectrum.

In the present disclosure, the position reference information may be transmission configuration information, transmitted by a base station, of the unlicensed spectrum, and may also be a preset signal, for example, a pilot signal, detected by the UE on a fixed time-frequency resource or a preset time-frequency resource, to enable the UE to determine the data transmission starting position on the unlicensed spectrum according to the preset signal.

That is, in <NUM>, the transmission configuration information transmitted by the base station for the unlicensed spectrum may be received, or the preset signal used for identifying the data transmission starting position on the unlicensed spectrum may be detected.

In <NUM>, the data transmission starting position on the unlicensed spectrum is determined according to the position reference information.

According to different position reference information, the UE determines data transmission starting position information of a channel of the unlicensed spectrum in the following two manners.

A first manner: the data transmission starting position on the unlicensed spectrum is determined according to the transmission configuration information transmitted by the base station.

If the transmission configuration information transmitted by the base station directly includes indication information of a data transmission starting position in a preset time window, the UE may directly determine the data transmission starting position on the unlicensed spectrum.

If the transmission configuration information transmitted by the base station includes a target index representing configuration information of data transmission starting positions, the UE queries a preset index list according to the target index to determine target configuration information of the data transmission position.

The preset index list includes a correspondence between a preset index and configuration information of data transmission starting positions. Exemplarily, the preset index list may be shown in Table <NUM>.

If the target index in the transmission configuration information received by the UE is <NUM>, it is obtained by querying Table <NUM> that the transmission starting position, configured by the base station, on the unlicensed spectrum is {<NUM>, <NUM>, <NUM>, <NUM>}.

A second manner: the UE determines the data transmission starting position on the unlicensed spectrum according to the detected preset signal.

In the embodiment of the present disclosure, in condition that the base station does not detect any idle channel of the unlicensed spectrum, the base station may configure the preset signal on the fixed time-frequency resource or a configurable time-frequency resource to notify the UE of the data transmission starting position for the unlicensed spectrum.

In such case, if the system predetermines to set the preset signal on the fixed time-frequency resource, the UE may detect the preset signal on the fixed time-frequency resource and then determine the data transmission starting position on the unlicensed spectrum according to a position of the preset signal and a preset transmission position configuration rule. The preset transmission position configuration rule may be that the position of the preset signal is the data transmission starting position on the unlicensed spectrum. Exemplarily, referring to a schematic diagram of an information transmission application scenario according to an exemplary embodiment in <FIG>, the UE detects pilot information <NUM> at positions of symbols <NUM>, <NUM>, <NUM> and <NUM> of a subframe and may determine that the symbols <NUM>, <NUM>, <NUM> and <NUM> of the subframe are data transmission starting positions where the channel of the unlicensed spectrum may be accessed.

In another embodiment of the present disclosure, the preset transmission position configuration rule may also be that a preset position after the preset signal is the data transmission starting position on the unlicensed spectrum. For example, a second symbol after the preset signal is determined as the data transmission starting position on the unlicensed spectrum according to the preset rule.

In another embodiment of the present disclosure, the base station may also configure the preset signal on the configurable time-frequency resource to indicate the data transmission starting position on the unlicensed spectrum. In such case, the UE acquires configuration information of a target time-frequency resource and determines a time-frequency range of the target time-frequency resource according to the configuration information at first, and then detects the preset signal in the target time-frequency resource according to the abovementioned manner and determines the data transmission starting position on the unlicensed spectrum according to the preset signal.

In <NUM>, information transmission with a base station is performed using a channel of the unlicensed spectrum according to the data transmission starting position.

Corresponding to the implementation mode of the base station side, implementation of the operation in <NUM> may also include at least one of the following conditions.

A first condition: the UE may receive downlink information sent by the base station in the channel of the unlicensed spectrum according to the data transmission starting position on the unlicensed spectrum.

A second condition: the UE, after detecting an idle channel of the unlicensed spectrum, accesses the channel of the unlicensed spectrum by use of the data transmission starting position on the unlicensed spectrum and sends uplink information to the base station through the channel of the unlicensed spectrum. Correspondingly, the base station, after acquiring indication information about that the UE has detected the idle channel of the unlicensed spectrum, may receive the uplink information sent by the UE through the channel of the unlicensed spectrum based on the target configuration information of the data transmission starting position.

According to the present invention, the UE determines the transmission configuration information of the system for the unlicensed spectrum through the acquired position reference information, i.e., the configuration information of the data transmission starting position in the preset time window, and further detect the information transmitted by the base station through a resource of the unlicensed spectrum according to the data transmission starting position, or, after detecting an idle channel resource of the unlicensed spectrum, send the uplink information to the base station by use of the transmission configuration information. Through the flexibly configured data transmission starting position, the probability of transmitting the information through resources of the unlicensed spectrum may be increased, a utilization rate of idle resources of the unlicensed spectrum may be increased, and the data transmission efficiency is further improved.
