Description

Communication resource selection method, handheld intelligent terminal and access device Technical field

The present invention relates to the field of communications technologies, and in particular, to a communication resource selection method in a vehicle networking system, a handheld intelligent terminal and an access device.

Background technique

Vehicle to Everything (V2X) is a vehicle networking project approved by the Third Generation Partnership (3GPP) Radio Access Network (RAN) #72. The main research is based on long-term The Internet Terminology message transmission scheme of the Long Term Evolution (LTE) includes: as shown in FIG. 1 , Vehicle to Vehicle (V2V), Vehicle to Pedestrian (V2P), and Vehicle Road The method of communication (Vehicle to Infrastructure, V2I) and Vehicle to Network (V2N).

One end of the V2P communication is a Pedestrian User Equipment (P-UE) of the pedestrian, and the other end is a Vehicle User Equipment (V-UE). When the originating end of the V2P communication is a P-UE, the communication resource selection for the P-UE, the conclusion reached at the 3GPP RAN1#86 standardization conference is that the P-UE can adopt random selection when selecting the communication resource (random selection) ) or partial sensing.

The V2P communication may be based on a priority control (PC5) air interface terminal to direct communication (Device to Device, D2D) SL transmission scheme, as shown in FIG. 2A or FIG. 2B. The P-UE and P-UE are not directly connected to the Evolved Universal Terrestril Radio Access Network (E-UTRAN).

Since 3GPP has agreed that the P-UE can support the selection mechanism of two different communication resources, namely random selection or partial sensing. However, the choice mechanism for which communication resources to use is not discussed and defined. Theoretically, if the P-UE adopts a random selection mechanism, it has the advantages of power saving and processing complexity, but the probability of resource collision is greater, which will reduce the reliability of the P-UE transmitting data packet to a certain extent. If partial perceptual selection is adopted, the probability of resource collision is small, but there is a problem of high processing complexity and power consumption.

Therefore, whether using random selection or partial perceptual selection to select communication resources, power saving, processing complexity, and reliability cannot be achieved.

detailed description

In this embodiment, whether the P-UE itself can use partial sensing to select time-frequency resources is limited by its own capability, that is, whether it has a Sidelink Rx capability. Therefore, it is necessary to discuss and formulate specific selection methods of communication resources in consideration of the P-UE's own capabilities and the state in which it is located, in order to obtain performance tradeoffs in terms of power saving and processing complexity and reliability. The specific implementation plan is as follows:

On the one hand, an embodiment of the present invention provides a communication resource selection method, as shown in FIG. 3, including:

301: The handheld intelligent terminal receives the resource pool information sent by the access device, where the information included in the resource pool information includes: a time-frequency location of at least one available resource pool, whether the available resource pool is allowed to be randomly selected, and whether the available resource pool is allowed. Partial perceptual selection, and conditions that allow partial perceptual selection;

The handheld smart terminal may be any P-UE in the V2X network, for example, any handheld smart terminal such as a mobile phone, a tablet computer, a PDA (Personal Digital Assistant), a POS (Point of Sales), or the like.

In this embodiment, the condition for allowing partial sensing selection may generally be a condition that affects the partial sensing selection, for example, the current channel congestion rate of the P-UE, the traffic busyness corresponding to the current location of the P-UE, and the like.

The foregoing access device may be a device responsible for accessing the network by the P-UE, such as an E-UTRAN Node B (eNB) in the E-UTRAN of FIG. 2A or FIG. 2B.

302: The above-mentioned handheld intelligent terminal selects the above-mentioned available from the random selection according to whether the handheld intelligent terminal has the secondary link receiving capability and whether the condition for allowing the partial sensing selection is met. The time-frequency resource is selected in the resource pool, or the time-frequency resource is selected from the above-mentioned available resource pool that allows partial sensing selection.

It can be understood by those skilled in the art that, since the P-UE has no sub-link reception capability, the P-UE will not have the capability of partial perceptual selection, and therefore, in the case that the P-UE has no sub-link reception capability, Time-frequency resources are not selected in a way that is partially perceptually chosen. In the case that the P-UE has the sub-link receiving capability, the P-UE will have the capability of partial sensing. In other words, when the P-UE has the sub-link receiving capability, the time-frequency resource is selected by using the partial sensing selection. Or, it is possible to select time-frequency resources by means of random selection. Considering that P-UE selects time-frequency resources in a random selection manner, it has the advantages of power saving and low processing complexity, but has the disadvantage of large resource collision probability, which will reduce the reliability of P-UE transmitting data packets to a certain extent. The P-UE selects time-frequency resources by means of partial perceptual selection, and vice versa. Therefore, when the P-UE has the secondary link receiving capability, the time-frequency resource can be selected according to the resource pool information sent by the access device. The specific selection manner is not limited by the embodiment of the present invention.

As can be seen from the foregoing technical solutions, the embodiment of the present invention has the following advantages: the access device configures the time-frequency location of the resource pool, allows random selection, allows partial perceptual selection, and allows in the resource pool configured for the P-UE. Partially aware of the selection conditions, which can facilitate the P-UE to adopt an adaptive time-frequency resource selection method according to its own conditions, thereby simultaneously satisfying the processing complexity, reliability, and power saving requirements.

In an optional implementation manner, the embodiment of the present invention further provides an implementation scheme for determining a time-frequency resource in a specific manner of determining a random selection or a partial perceptual selection, as follows: whether the handheld intelligent terminal is based on whether the handheld intelligent terminal has a secondary Selecting time-frequency resources from the available resource pools that allow random selection, or selecting time-frequency resources from the available resource pools that allow partial sensing selection, including:

The handheld smart terminal is configured to select a time-frequency resource from the available resource pool that is allowed to be randomly selected, if the handheld intelligent terminal does not have the secondary link receiving capability;

Alternatively, the handheld smart terminal is configured to select a time-frequency resource from the available resource pool that allows the partial sensing to select, if it is determined that the handheld intelligent terminal has a secondary link receiving capability and meets the condition for allowing the partial sensing selection;

Alternatively, in the case where it is determined that the handheld smart terminal has the secondary link receiving capability and does not meet the above-described conditions for allowing the partial sensing selection, the above-mentioned handheld intelligent terminal allows the above-mentioned available from the random selection. Select time-frequency resources in the resource pool.

In this embodiment, the implementation manner of selecting the time-frequency resource in the manner of determining the random selection or the partial perceptual selection in the above three manners is performed in the actual execution process, so it should not be understood that the above three implementation schemes are P-UE. A scenario that needs to be executed at the same time.

In an optional implementation, the embodiment further provides a specific implementation manner in which the access device sends the resource pool information to the P-UE: the handheld intelligent terminal receives the resource pool information sent by the access device, including:

The handheld intelligent terminal receives the resource pool information sent by the access device by using broadcast or by using radio resource control signaling.

It should be noted that the manner in which the foregoing access device sends information to the P-UE may be selected based on the communication mode adopted between the access device and the P-UE, and the above solution should not be construed as exhaustive of all optional implementations.

In an optional implementation manner, the P-UE may not be able to select an appropriate time-frequency resource from the resource pool. Therefore, the embodiment of the present invention further provides an implementation scheme for the P-UE to coordinate with the access device, as follows: The above-mentioned handheld intelligent terminal receives the resource pool information sent by the access device, and further includes:

The handheld intelligent terminal sends auxiliary information to the access device, and receives the resource pool information adjusted by the access device according to the auxiliary information.

In this embodiment, the auxiliary information is fed back by the P-UE for the access device to adjust the resource pool information. It can be understood that the auxiliary information may be any parameter that affects resource pool allocation.

In an optional implementation, the specific implementation scheme for the P-UE to feed the auxiliary information to the access device is also provided. The following: the sending, by the handheld intelligent terminal, the auxiliary information to the access device includes:

The handheld intelligent terminal sends the auxiliary information to the access device by using radio resource control signaling.

In an optional implementation manner, an example of optional parameters of the auxiliary information is also provided, as follows: the foregoing auxiliary information includes:

The current location and/or channel congestion rate of the handheld smart terminal described above.

Since the auxiliary information may be any parameter that affects the allocation of the resource pool, the above examples should not be construed as limiting the uniqueness of the embodiments of the present invention.

In an optional implementation, the embodiment of the present invention further provides the following solution, as the method is used to compare the power consumption and the power consumption is not necessarily selected.

After the handheld intelligent terminal determines to select the time-frequency resource from the available resource pool selected by the permission part, if the available time-frequency resource is not perceived after the predetermined time, the time-frequency resource is selected from the available resource pool that is allowed to be randomly selected.

In this embodiment, the power saving and the reliability can be further taken into consideration, and the long-term partial sensing is prevented from selecting a suitable time-frequency resource, thereby consuming a large amount of power and processor resources.

In an optional implementation manner, parameters that affect partial sensing selection are also provided, as follows: the foregoing conditions for allowing partial sensing selection include: a congestion rate threshold exceeding a channel congestion rate and/or a current location of the handheld intelligent terminal. Traffic congestion in the area exceeds the busyness threshold.

It should be noted that there may be many parameters that affect partial sensing. The above examples should not be construed as limiting the uniqueness of the embodiments of the present invention.

The following embodiment will be exemplified by a V2P system composed of an eNB and a P-UE, as shown in FIG. 4, including:

401: The eNB sends the resource pool information configured by the eNB to the P-UE to the P-UE by using a broadcast message or Radio Resource Control (RRC) signaling.

The resource pool information may include time-frequency locations of one or more resource pools that can be used; whether each resource pool allows random selection; whether each resource pool allows partial partial sensing; Resource pools do the conditions for partial sensing; and so on.

More specifically, the condition that the resource pool performs partial sensing may be a comprehensive judgment of one or several variables, such as a threshold of a channel busy ratio (CBR) (the threshold is allowed to select a communication resource based on partial sensing), the location Information (if the location of the P-UE corresponds to a busy location, allowing communication resources to be selected based on partial sensing), and so on.

402: The P-UE determines whether it has a sidelink receiving capability. If not, the P-UE selects a time-frequency resource in a resource pool that allows random selection. If yes, go to 403.

403: The P-UE determines whether the current state of the P-UE is consistent with the condition for performing partial sensing.

The current state information of the P-UE includes: the current power, the current channel congestion rate, the current geographic location, and the like; and may also perform comprehensive judgment based on the usage conditions included in the resource pool information configured by the eNB. If not, the P-UE selects a time-frequency resource in a resource pool that allows random selection. If it is met, the P-UE selects a time-frequency resource in a resource pool that allows partial sensing.

In particular, the P-UE may selectively report auxiliary information to the eNB (channel congestion rate, geographic location) And so on, so that the eNB dynamically adjusts the usage conditions of the resource pool according to the current situation, and delivers the newly configured resource pool information to the P-UE through RRC signaling.

404: The P-UE does not perceive the available time-frequency resources based on the partial sensing within a certain time T, and then transfers to the time-frequency resource from the resource pool that allows the random selection.

In the embodiment of the present invention, the P-UE achieves power saving, processing complexity, and reliability by selecting communication resources based on the P-UE's own capabilities and the state in which it is located.

The second embodiment of the present invention provides another method for selecting a communication resource, which is implemented on the side of the access device corresponding to the foregoing embodiment, and is specifically as follows:

The access device determines resource pool information, where the information included in the resource pool information includes: a time-frequency location of at least one available resource pool, whether the available resource pool allows random selection, and whether the available resource pool allows partial sensing selection, And conditions that allow partial perceptual selection;

The access device sends the resource pool information to the handheld smart terminal by broadcasting or by using radio resource control signaling.

Further, the embodiment of the present invention further provides an implementation scheme for updating resource pool information, as follows: The method further includes:

Receiving the auxiliary information sent by the handheld intelligent terminal by using the radio resource control signaling, and determining the adjusted resource pool information according to the auxiliary information;

And the access device sends the adjusted resource pool information to the handheld intelligent terminal by using a broadcast or by using radio resource control signaling.

The present invention provides a handheld intelligent terminal, as shown in FIG. 5, including:

The information receiving unit 501 is configured to receive resource pool information sent by the access device, where the information included in the resource pool information includes: a time-frequency location of at least one available resource pool, whether the available resource pool allows random selection, and the available resource pool Whether partial perceptual selection is allowed, and conditions that allow partial perceptual selection;

The resource selection unit 502 is configured to select a time-frequency resource from the available resource pool that is allowed to be randomly selected according to whether the handheld smart terminal has the secondary link receiving capability and whether the condition for allowing the partial sensing selection is met, or The time-frequency resource is selected in the above-mentioned available resource pool selected by the partial sensing.

The handheld smart terminal may be any P-UE in the V2X network, such as a mobile phone, a tablet, a PDA (Personal Digital Assistant), and a POS (Point of Sales, Any handheld smart terminal such as a sales terminal).

In this embodiment, the condition for allowing partial sensing selection may generally be a condition that affects the partial sensing selection, for example, the current channel congestion rate of the P-UE, the traffic busyness corresponding to the current location of the P-UE, and the like.

The foregoing access device may be a device responsible for accessing the network by the P-UE, such as an E-UTRAN Node B (eNB) in the E-UTRAN of FIG. 2A or FIG. 2B.

It can be understood by those skilled in the art that, since the P-UE has no sub-link reception capability, the P-UE will not have the capability of partial perceptual selection, and therefore, in the case that the P-UE has no sub-link reception capability, Time-frequency resources are not selected in a way that is partially perceptually chosen. In the case that the P-UE has the sub-link receiving capability, the P-UE will have the capability of partial sensing. In other words, when the P-UE has the sub-link receiving capability, the time-frequency resource is selected by using the partial sensing selection. Or, it is possible to select time-frequency resources by means of random selection. Considering that P-UE selects time-frequency resources in a random selection manner, it has the advantages of power saving and low processing complexity, but has the disadvantage of large resource collision probability, which will reduce the reliability of P-UE transmitting data packets to a certain extent. The P-UE selects time-frequency resources by means of partial perceptual selection, and vice versa. Therefore, when the P-UE has the secondary link receiving capability, the time-frequency resource can be selected according to the resource pool information sent by the access device. The specific selection manner is not limited by the embodiment of the present invention.

As can be seen from the foregoing technical solutions, the embodiment of the present invention has the following advantages: the access device configures the time-frequency location of the resource pool, allows random selection, allows partial perceptual selection, and allows in the resource pool configured for the P-UE.
