Detailed Description

To make the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

The steps illustrated in the flow charts of the figures may be performed in a computer system such as a set of computer-executable instructions. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.

Typical applications of side-link (sildelink) communication include Device-to-Device (D2D) communication and Vehicle networking (V2X) communication. The Vehicle to Vehicle (V2X) communication includes Vehicle to Vehicle (V2V), vehicle to person (V2P), and Vehicle to road (V2I). For a short-distance communication user capable of applying the Sidelink communication, the Sidelink communication not only saves wireless spectrum resources, but also reduces the data transmission pressure of a core network, can reduce the occupation of system resources, increases the spectrum efficiency of a cellular communication system, reduces the communication delay and saves the network operation cost to a great extent.

Current sildelink designs only consider Intelligent Transport System (ITS) spectrum and licensed spectrum allocated to network operators, and do not consider designs for unlicensed spectrum. In a related Sidelink, a time slot may include Sidelink channels, and the Sidelink channels in a time slot include a Physical Sidelink Control Channel (PSCCH), a Physical Sidelink shared channel (PSCCH), and a Physical Sidelink Feedback Channel (PSFCH) channel. In addition, one slot also includes OFDM symbols in which no sidelink channel is transmitted for the entire symbol. In the Sidelink communication, a sending device selects resources for signaling/data transmission, and one way is that a central node (e.g. a base station) determines the resources used by the device for transmission through scheduling of the central node, and notifies the resources to a terminal through signaling. Correspondingly, another method for selecting resources is a contention-based resource selection method, in which a device autonomously selects resources for transmitting signaling/data in a resource pool by monitoring the use condition of resources within the resource pool and monitoring the result. The contention-based resource selection method may also be referred to as a terminal-autonomous resource selection method.

On unlicensed spectrum, a successful Listen Before Talk (LBT) channel can transmit. The LBT means that a communication node needs to contend for resources, and the communication node can transmit information on the time-frequency resource only if the time-frequency resource contention succeeds. More specifically, in the LBT mechanism, a communication node performs a channel access procedure (listening whether a channel is idle) before information transmission, and the communication node can perform information transmission only if the channel is idle. The LBT mechanism is a typical channel access mechanism, and a terminal may perform a channel access procedure such as LBT, and perform channel occupation after monitoring that a channel is idle.

For unlicensed spectrum, a communication node needs to perform a channel access procedure to evaluate whether a channel is idle/available before sending information. When the channel is assessed to be free/available, the communication node may transmit information on the unlicensed spectrum channel. Otherwise, the communication node may not transmit information on the unlicensed spectrum channel. When a channel is unavailable, typically because other communication nodes are occupying the channel, e.g., WIFI nodes are occupying the channel.

In the related sidelink technique, reserved resources indicated by a communication node are designed for a licensed spectrum. The communication node may indicate only 1-3 reserved resources by the associated indicated mechanism for reserving resources. This resource indication mechanism cannot reserve more than 3 consecutive resources of time slots.

It is advantageous that the resource indication mechanism for unlicensed spectrum of the present disclosure can indicate/reserve more than 3 time slots of consecutive resources. For example, when the communication node selects more than 3 resources with consecutive time slots and indicates/reserves more than 3 resources with consecutive time slots, the probability of channel access failure can be reduced. Specifically, more consecutive time slots may be transmitted to allow the communication node to perform channel occupation. Conversely, when a communication node transmits in discontinuous time slots, the channel is liable to be preempted by other communication nodes during the transmission interruption, so that the communication node cannot preempt the channel when it wants to transmit information again during the transmission interruption.

In view of the above problem, the present disclosure provides an information transmission method, and in an exemplary embodiment, fig. 1 is a schematic flow chart of an information transmission method provided in an embodiment of the present application; the method may be applied to the case of performing time domain resource indication, and the method may be performed by an information transmission apparatus provided in the embodiments of the present disclosure, and the apparatus may be implemented by software and/or hardware and integrated on a first communication node, and the first communication node may be one or more of a base station, a network, and a UE.

and S110, determining time domain resource indication information.

And S120, sending the control information at the first time.

The control information includes the time domain resource indication information and a bit field for indicating a continuous time;

In the 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, and the second communication node can determine the target time of the indicated resource based on the second time. The target time may characterize a start time at which the first communication node indicates or occupies a resource. 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. The different target times may be determined based on different times, including a first time, a second time, a third time, and so on. In 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 a continuous time domain resource or may indicate a discrete time domain resource. The number of resources indicated by the time domain resource indication information is flexible and can be determined based on the independent variable of the time domain resource indication information. The argument comprises the second time, the third time, etc. The more time the argument is included, the greater the amount of resources indicated. The time included by the argument may be an offset value of the first time, the sum of the included time and the first time is determined as a target time, different targets may correspond to different durations, and the durations corresponding to the target time are indicated by different bit fields or different code points of the same bit field.

The present disclosure may indicate the start time of the indicated resource through time domain resource indication information, and indicate the time during which the start time lasts through a bit domain for indicating the duration. Thereby enabling flexible indication of time domain resources. Different target times may correspond to one duration or different durations. The durations corresponding to different target times may be partially the same, for example, the durations corresponding to the first target time and the second target time are the same.

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

The bit field may be a bit indicating a continuous time. The bit field may be used to indicate the time that the indicated resource is contiguous from the start time. The number of bit fields is not limited and may be at least one bit.

The control information of the application realizes flexible indication of resources. The first communication node can indicate or occupy more time slots based on the control information, reducing the probability of the channel being preempted by other communication nodes. If different combinations of the first time and the second time are taken as target times, the duration is taken as the time needing to be continued corresponding to the target times, the first time is one target time of the indicated resources, the sum of the second time and the first time is the other target time of the indicated resources, the duration bit field is used for indicating the duration, and the indication of the plurality of resources is completed.
