Detailed ways

The embodiments of the present application will be described below with reference to the accompanying drawings.

The operations shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions. Also, although a logical sequence is shown in the flowcharts, in some cases, the operations shown or described can be performed in a sequence different from that shown here.

The applications of sidelink communication include device-to-device (D2D) communication and vehicle-to-everything (V2X) communication. Among them, vehicle-to-everything (V2X) communication includes vehicle-to-vehicle (V2V), vehicle-to-pedestrian (V2P), and vehicle-to-infrastructure (V2I). For short-distance communication users who can apply Sidelink communication, Sidelink communication not only saves wireless spectrum resources, but also reduces the data transmission pressure of the core network, can reduce system resource usage, increase the spectrum efficiency of the cellular communication system, reduce communication latency, and save network operating costs to a large extent.

The design of Sidelink only considers the spectrum of Intelligent Transport System (ITS) and the licensed spectrum allocated to network operators, and does not consider the design for unlicensed spectrum. In the relevant Sidelink, a time slot can contain some Sidelink channels. The Sidelink channels in a time slot include the Physical sidelink control channel (PSCCH), the Physical sidelink shared channel (PSSCH) and the Physical sidelink feedback channel (PSFCH). In addition, a time slot also includes Orthogonal Frequency Division Multiplexing (OFDM) symbols in which no sidelink channel is sent throughout the symbol. In Sidelink communication, one way for the sending device to select resources for signaling/data transmission is through scheduling by a central node (such as a base station). The central node determines the resources used by the device for transmission and notifies the terminal through signaling. Correspondingly, another resource selection method is a resource selection method based on competition. In the resource selection method based on competition, the device monitors the usage of resources within the resource pool, and autonomously selects resources for sending signaling/data in the resource pool based on the monitoring results. The resource selection method based on competition can also be called a terminal autonomous resource selection method.

In the unlicensed spectrum, only channels that have successfully listened before talking (LBT) can transmit. The so-called LBT means that communication nodes need to compete for resources. Only when the competition for time-frequency resources is successful can the communication node transmit information on the time-frequency resources. In the LBT mechanism, the communication node performs a channel access process (listens to see if the channel is idle) before transmitting information. Only when the channel is idle can the communication node transmit information. The above-mentioned LBT mechanism is a channel access mechanism. The terminal can perform a channel access process such as LBT, and occupy the channel after listening to the idle channel.

For unlicensed spectrum, communication nodes need to perform channel access before sending information. The communication node determines whether the channel is idle/available. If the channel is idle/available, the communication node can send information on the unlicensed spectrum channel. Otherwise, the communication node cannot send information on the unlicensed spectrum channel. When the channel is unavailable, it is usually because other communication nodes are occupying the channel, such as a WIFI node.

In the related sidelink technology, the reserved resources indicated by the communication node are designed for the licensed spectrum. Through the related mechanism of indicating reserved resources, the communication node can only indicate 1-3 reserved resources. This resource indication mechanism cannot reserve more than 3 consecutive time slots.

The resource indication mechanism of the present application for unlicensed spectrum can indicate/reserve more than 3 consecutive time slots of resources. For example, when a communication node selects more than 3 consecutive time slots of resources and indicates/reserve more than 3 consecutive time slots of resources, the probability of channel access failure can be reduced. Transmission of more consecutive time slots allows communication nodes to occupy channels. On the contrary, when a communication node transmits on discontinuous time slots, the channel is easily seized by other communication nodes during the transmission interruption, resulting in the communication node being unable to seize the channel when transmitting information again after the transmission interruption.

The present application provides an information transmission method. In an exemplary embodiment, Figure 1 is a flow chart of an information transmission method provided in an embodiment of the present application. The method can be applicable to the case of performing time domain resource indication. The method can be executed by an information transmission device provided in an embodiment of the present application. The device can be implemented by software and/or hardware and integrated on a first communication node. The first communication node can be one or more of a base station, a network and a UE.

As shown in FIG. 1 , the present application provides an information transmission method, including S110-S120:

S110: Determine time domain resource indication information.

S120. Send control information as soon as possible.

The control information includes the time domain resource indication information and a bit field for indicating continuous time; wherein the time domain resource indication information is a function of a second time.

In the present application, the time domain resource indication information is a function of the second time. After the first communication node sends the time domain resource indication information to the second communication node, the second communication node can determine the second time based on the time domain resource indication information and the function corresponding to the time domain resource indication information. The second communication node can determine the target time of the indicated resource based on the second time. The target time can represent the start time of the resource indicated or occupied by the first communication node. The target time includes the first target time, the second target time, the third target time, etc. The present application does not limit the number of target times. Different target times can be determined based on different times, including the first time, the second time, the third time, etc. When determining the target time, the second time and the third time can be used as time offset values to determine the target time. The time domain resource indication information can indicate continuous time domain resources or discrete time domain resources. The number of resources indicated by the time domain resource indication information is more flexible and can be determined based on the independent variable of the time domain resource indication information. Independent variable The variables include the second time, the third time, etc. The more time included in the independent variable, the more resources are indicated. The time included in the independent variable can be used as an offset value of the first time, and the sum of the included time and the first time is determined as the target time. Different target times can correspond to different durations, and the duration corresponding to the target time is indicated by different bit fields or different code points in the same bit field.

The present application can indicate the start time of the indicated resource through the time domain resource indication information, and indicate the duration of the start time through the bit field used to indicate the duration. Thereby, flexible indication of time domain resources is achieved. Different target times can correspond to one duration or different durations. The durations corresponding to different target times can be partially the same, such as the first target time and the second target time have the same duration.

This embodiment does not limit the content of the function corresponding to the time domain resource indication information, as long as the communicating parties are consistent.

The bit field may be a bit indicating continuous time. The bit field may be used to indicate the continuous time of the indicated resource from the start time. The present application does not limit the number of bit fields, which may be at least one bit.

An embodiment of the present application provides an information transmission method, which can indicate the target time of the indicated resource by sending control information including time domain resource indication information, and can indicate the duration of the indicated resource by a bit field used to indicate continuous time in the control information. Flexible indication of resources is achieved through the control information of the present application. The first communication node can indicate or occupy more time slots based on the control information, thereby reducing the probability that the channel is preempted by other communication nodes. For example, different combinations of the first time and the second time are used as the target time, and the duration is the required duration corresponding to the target time. The first time is a target time for the indicated resource, and the sum of the second time and the first time is another target time for the indicated resource. The bit field is used to indicate the duration, and the indication of multiple resources is completed. If you want to indicate more time domain resources, you can add an independent variable of the time domain resource indication information, and the indication method is not limited here.
