Detailed ways

In order to make the purpose, technical solution and advantages of the application clearer, the embodiments of the application will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

The steps shown in the flowcharts of the figures may be performed in a computer system, such as a set of computer-executable instructions. Also, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

Typical applications of Sidelink communication include Device-to-Device (D2D) communication and Vehicle to Everything (V2X) communication. Among them, the Internet of Vehicles (V2X) communication includes Vehicle to Vehicle (V2V), Vehicle to Pedestrian (V2P), 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, which can reduce system resource occupation, increase the spectrum efficiency of cellular communication systems, and reduce communication delays. And save network operation cost to a great extent.

The current design of Sidelink only considers the intelligent transportation system (Intelligent Transport System, ITS) spectrum and the licensed spectrum allocated to network operators, and does not take into account the design for unlicensed spectrum. In the related Sidelink, a time slot can contain some Sidelink channels, and the Sidelink channels in a time slot include the side link control channel (Physical sidelink control channel, PSCCH), the side link shared channel (Physical sidelink shared channel, PSSCH) And the side link feedback channel (Physical sidelink feedback channel, PSFCH) channel. In addition, a time slot also includes an OFDM symbol in which no sidelink channel is transmitted in the whole symbol. In Sidelink communication, the sending device selects the resources for signaling/data transmission. One way is through the scheduling of the 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 method for selecting resources is the resource selection method based on competition. In the resource selection method based on competition, the device independently selects resources in the resource pool by monitoring the usage of resources within the resource pool and the monitoring results. A resource for sending signaling/data. The contention-based resource selection method may also be called a terminal-autonomous resource selection method.

On the unlicensed spectrum, only the channels with successful Listen Before Talk (LBT) can be transmitted. The so-called LBT means that communication nodes need to compete for resources, and only when the time-frequency resource competition is successful can the communication node perform information transmission on the time-frequency resource. More specifically, in the LBT mechanism, the communication node performs a channel access process (monitoring whether the channel is idle) before information transmission, and the communication node can perform information transmission only when the monitoring indicates that the channel is idle. The above-mentioned LBT mechanism is a typical channel access mechanism. The terminal can perform a channel access process such as LBT, monitor that the channel is idle, and then occupy the channel.

For unlicensed spectrum, before sending information, the communication node needs to perform a channel access process to evaluate whether the channel is idle/available. When it is evaluated that the channel is free/available, the communication node may send information on the unlicensed spectrum channel. Otherwise, the communication node may not 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 WIFI nodes are occupying the channel.

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

The resource indication mechanism for the unlicensed spectrum in the present disclosure can indicate/reserve more than 3 consecutive resources of time slots, which is beneficial. For example, when the communication node selects resources with more than 3 consecutive time slots and instructs/reserves resources with more than 3 consecutive time slots, the probability of channel access failure can be reduced. Specifically, the transmission of more consecutive time slots may allow the communication node to occupy the channel. On the contrary, when a communication node transmits in discontinuous continuous time slots, the channel is likely to be preempted by other communication nodes during the interruption of transmission, so that the communication node cannot seize the channel when the communication node wants to transmit information after the transmission interruption.

Based on the above problems, the present disclosure provides an information transmission method. In an exemplary embodiment, FIG. 1 is a schematic flow chart of an information transmission method provided by the embodiment of the present application; this method can be applied to time-domain resource indication In the case of the situation, the method can be executed by the information transmission device provided by the embodiment of the present disclosure, the device can be implemented by software and/or hardware, and integrated on the first communication node, the first communication node can be a base station, network and UE one or more.

As shown in Figure 1, an information transmission method provided by this application includes the following steps:

S110. Determine time-domain resource indication information.

S120. Send the control information at the first time.

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 the second time.

In this 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 based on the time domain resource indication information and the time domain resource indication information Corresponding to the function, the second time can be determined, and the second communication node can determine the target time of the indicated resource based on the second time. The target time may represent the start time of the resources indicated or occupied by the first communication node. The target time includes a first target time, a second target time, a third target time, and the like. The number of target times included in the target time is not limited. Different target times may be determined based on different times, and the different times include a first time, a second time, a third time, and so on. When determining the target time, the second time and the third time may be used as time offset values to determine the target time. The time-domain resource indication information may indicate continuous time-domain resources, or may indicate discrete time-domain resources. The quantity of resources indicated by the time-domain resource indication information is relatively flexible, and may be determined based on an argument of the time-domain resource indication information. The independent variables include second time, third time, and so on. The more time the argument includes, the greater the number of resources indicated. The time included in the argument can be used as the offset value of the first time, and the sum of the included time and the first time is determined as the target time. Different targets can correspond to different durations, through different bit fields Or different code points of the same bit field indicate the duration corresponding to the target time.

In the present disclosure, the time-domain resource indication information may be used to indicate the start time of the indicated resource, and the bit field used to indicate the duration may be used to indicate the duration of the start time. In this way, flexible indication of time domain resources is realized. Different target times may correspond to one duration, or may correspond to different durations. The durations corresponding to different target times may be partly the same, for example, the durations corresponding to the first target time and the second target time are the same.

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

A bit field may be bits indicating a continuous time. A bit field may be used to indicate how long the indicated resource continues from the start time. The number of bit fields is not limited, and may be at least one bit.

The embodiment of the present application provides an information transmission method. By sending control information including time domain resource indication information, the target time of the indicated resource can be indicated, and the indicated resource can be indicated through the bit field used to indicate the continuous time in the control information. duration. Flexible indication of resources is realized through the control information of the present application. Based on the control information, the first communication node can indicate or occupy more time slots, 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 of the indicated resource, and the second time and the first time The sum of is another target time of the indicated resource, the duration bit field is used to indicate the duration, and the indication of multiple resources is completed.
