Description

Technical Field

[0001] This application relates to the field of communications, and more specifically, to a method for instructing resource allocation, a method for using resource allocation, a device for instructing resource allocation, a device for using resource allocation, a processor, and a communication system. Background Technology

[0002] For V2X (vehicle to everything) transmissions in NR (New Radio) networks, UE (User Equipment) can autonomously select resources for information transmission according to certain rules. Specifically, the UE determines candidate resources through a sensing process, then randomly selects resources from the candidate resources for the first and subsequent transmissions, and indicates the resources used for this transmission and the resource reservation period in the SCI (Sidelink Control Information) of each transmission.

[0003] However, due to the presence of hidden nodes, UEs cannot perceive the transmission resources of these hidden nodes during resource perception. This leads to different UEs selecting the same transmission resources for data transmission, resulting in conflicts and preventing normal data transmission. For scenarios with numerous hidden nodes in the network, the current scheme for sending cooperation information has the following problems: some UEs not participating in sending / receiving cooperation information cannot learn about potential hidden nodes through UE-A, and resource conflicts still exist; for UE-A, if cooperation information is sent based on a request message from UE-B, UE-B may select the same transmission resources as hidden nodes around UE-A when sending the request message itself, resulting in conflicts and preventing the request message from being sent correctly. Summary of the Invention

[0010] Optionally, when the congestion level of the PSSCH channel or PSCCH channel is greater than the sixth threshold but less than the seventh threshold, the target UE broadcasts the transport channel resource information.

[0011] Optionally, the congestion level of the PSSCH channel or PSCCH channel is determined based on at least one of CBR and CR; and / or, when the congestion level is not greater than the sixth threshold, the target UE stops broadcasting the transport channel resource information; and / or, when the congestion level is not less than the seventh threshold, the target UE stops broadcasting the transport channel resource information.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0026] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0027] As mentioned in the background section, hidden nodes in the prior art cause different UEs to select the same transmission resources, thereby generating resource conflicts. In order to solve the above problems, in a typical embodiment of this application, a resource allocation indication method, a resource allocation usage method, a resource allocation indication device, a resource allocation usage device, a processor, and a communication system are provided.

[0028] According to embodiments of this application, a method for instructing resource allocation is provided.

[0029] Figure 1 This is a flowchart of a resource allocation instruction method according to an embodiment of this application. For example... Figure 1 As shown, the method includes the following steps:

[0030] Step S101: The target UE broadcasts transmission channel resource information, wherein the number of hidden nodes within the preset range where the target UE is located meets the preset conditions, and the transmission channel resource information is used to indicate the transmission channel resources for the target UE to receive data.

[0031] In the above steps, such as Figure 2As shown in the figure, the above-mentioned hidden nodes are illustrated. UE-1100, UE-2101, UE-3102, and UE-4103 are multiple UEs in the cell. UE-1100 can listen to the transmission channels of UE-2101 and UE-3102, and UE-3102 can listen to the transmission channels of UE-1100 and UE-4103. UE-2101 and UE-3102 are hidden nodes of each other, and UE-2101 and UE-4103 are hidden nodes of each other, and they cannot listen to each other's transmission channels. At a certain moment, UE-2101 transmits data to UE-1100 via channel A. Subsequently, UE-3102 also needs to transmit data (possibly to UE-1100 or UE-4103). However, because UE-3102 cannot detect the transmission channel A used by UE-2101, it may also choose transmission channel A. In this situation, UE-1100 receives data from both UE-2101 and UE-3102 simultaneously on the same transmission channel A, resulting in a conflict and potentially preventing the correct demodulation of data sent by UE-2101. The aforementioned preset range is a preset distance from the target UE, and the preset condition is a preset number of hidden nodes. If all UEs broadcast their transmission channel resources for receiving data, it may consume a large amount of bandwidth. Therefore, this method is preferably applicable to UEs with a large number of hidden nodes nearby, i.e., the target UE, broadcasting their transmission channel resource information for receiving data can improve resource utilization. The aforementioned method for determining the target UE can be performed periodically by the base station and indicated to the target UE via RRC (Radio Resource Control) signaling or MAC CE (Medium Access Control Control Element); alternatively, it can be performed periodically by the UE. Furthermore, different determination periods can be configured based on the UE's movement speed within the cell. For example, if the UE moves quickly within the cell, a shorter determination period can be configured; if the UE moves slowly within the cell, a longer determination period can be configured.

[0032] In this embodiment of the invention, the target UE is a UE whose number of hidden nodes within a preset range meets a preset condition. The target UE broadcasts transmission channel resource information, which indicates the transmission channel resources for receiving data. This enables other UEs that receive the transmission channel resource information to avoid using the transmission channel resources for data transmission, thus solving the technical problem of resource conflicts caused by different UEs selecting the same transmission resources due to hidden nodes.

[0033] It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.

[0034] In one embodiment of this application, based on the above-described step S101, step S101 is further refined, specifically including: step S1011, identifying all UEs whose distance from the first UE is less than a first threshold as second UEs; step S1012, determining the number of first combinations in which the distance between two second UEs is greater than a second threshold; step S1013, when the number of first combinations is greater than a third threshold, identifying the first UE as the target UE. In the above steps, the distribution of UEs in the cell varies, and can be either concentrated or dispersed. The first UE can be the central UE among multiple UEs, or any one of the multiple UEs. The above method can quickly determine the location information of the first UE. Furthermore, a first threshold can be configured corresponding to the transmit power of the UE to be judged, thereby accurately obtaining the actual coverage area of ​​the UE to be judged, and further accurately determining whether multiple UEs around the first UE are second UEs. Furthermore, for each pair of second UEs, a second threshold is preferably set based on the larger of the transmit powers of the two second UEs to more accurately determine whether the two second UEs in the pair are hidden nodes of each other. Therefore, the above method can quickly determine whether there are hidden nodes among the second UEs based on the location information of any two second UEs.

[0035] In another embodiment of this application, based on the above-described step S1011, step S1011 is further refined, including: step S10111, where the UEs in the cell are distributed in clusters, the UE located at the center of the cluster is determined as the first UE. In practical applications, there may be a special scenario where the UEs in the cell are distributed in clusters, the relative distance between the UEs in each cluster is relatively fixed, and there is a UE located at the center. This UE at the center can be determined as the first UE. The above method, after determining the first UE, saves the step of periodically determining the first UE because the UEs are distributed in clusters and the distance between the UEs is fixed, thus further saving energy consumption.

[0036] In another embodiment of this application, based on the above-described step S10111, step S10111 is further refined, specifically including: determining a second combination in which the change in distance between two UEs within a preset time period is less than a fourth threshold; and determining the same UE as the first UE when the number of the second combinations containing the same UE is greater than a fifth threshold. The method can calculate the distance between any two UEs among multiple UEs at multiple times, where one distance corresponds to two UEs at one time, and multiple distances correspond to two UEs at multiple times; then calculating the mean or variance of the multiple distances corresponding to any two UEs to measure the change in distance. In the above steps, the number of times can be configured according to actual conditions, and the change in distance can also be characterized by methods other than mean and variance. In the above steps, selecting the target UE through the UE's location information can reduce resource conflicts caused by a large number of hidden UE nodes, improving data transmission stability; and when there are few hidden UE nodes in the cell, it reduces unnecessary transmission channel occupation, further improving resource utilization.

[0037] In one embodiment of this application, based on the above step S101, the above step S101 is further refined, specifically including: step S1014, the target UE obtains the above transmission channel resource information according to the SCI sent by other UEs, and the above SCI is carried through the PSSCH channel or PSCCH channel.

[0038] In one embodiment of this application, based on the above-described step S101, step S101 is further refined, specifically including: step S1015, when the congestion level of the PSSCH channel or PSCCH channel is greater than a sixth threshold and less than a seventh threshold, the target UE broadcasts the aforementioned transmission channel resource information. In the above steps, to avoid congestion of transmission channel resources, the target UE can adaptively broadcast its transmission channel resources for receiving data based on the monitoring results of the PSSCH channel and / or PSCCH channel. Furthermore, in the above steps, the congestion level can be measured by channel parameters such as CBR or CR. When CBR or CR is between the seventh threshold and the sixth threshold, the UE broadcasts its transmission channel resources for receiving data to avoid resource conflicts.

[0039] In another embodiment of this application, step S1015 is further refined, specifically including: the congestion level of the PSSCH channel or PSCCH channel is determined according to at least one of CBR and CR; and / or, when the congestion level is not greater than the sixth threshold, the target UE stops broadcasting the transmission channel resource information; and / or, when the congestion level is not less than the seventh threshold, the target UE stops broadcasting the transmission channel resource information. In the above steps, CBR is used to evaluate the portion of the resource pool where the RSSI (Received Signal Strength Indicator) is higher than a certain threshold within a given time period. CR is the total number of sub-channels used by the UE for its transmission within a certain measurement period divided by the total number of configured sub-channels. When the Channel Busy Ratio (CBR) is higher than the seventh threshold, it indicates that the sidelink network is congested. The UE can choose to stop broadcasting its transmission channel resources used for receiving data to reduce the occupation of transmission channel resources. When the CBR is lower than the sixth threshold, it indicates that the sidelink network is idle. At this time, the probability of resource collision is very low, and the UE can choose to stop broadcasting its transmission channel resources used for receiving data to save energy. When the Channel Busy Ratio (CR) is higher than the seventh threshold, it indicates that the sidelink network is congested. The UE can choose to stop broadcasting its transmission channel resources used for receiving data to reduce the occupation of transmission channel resources. When the CR is lower than the sixth threshold, it indicates that the sidelink network is idle. At this time, the probability of resource collision is very low, and the UE can choose to stop broadcasting its transmission channel resources used for receiving data to save energy. Adaptively and dynamically broadcasting the transmission channel resources used for receiving data based on the monitoring results of the PSSCH channel and / or PSCCH channel can simultaneously take into account several aspects such as transmission channel load, UE energy saving, and transmission channel resource conflict. It can reduce the technical problem of different UEs selecting the same transmission resources and thus causing resource conflicts without aggravating sidelink network congestion and taking into account UE energy consumption.

[0040] This application also provides a method for using resource allocation, including:

[0041] Step S201: Receive transmission channel resource information, which is used to indicate the transmission channel resources for other UEs to receive data;

[0042] Step S202: Use channel resources other than the aforementioned transmission channel resources for data transmission.

[0043] In the above steps, the current UE can learn that the transmission channel resource has been selected for use by receiving transmission channel resource information broadcast by other UEs, which indicates the transmission channel resource for receiving data. Thus, the current UE can avoid selecting the transmission channel resource to transmit data, and therefore will not affect other UEs that broadcast the transmission channel resource information.

[0044] This application also provides a resource allocation indication device. It should be noted that the resource allocation indication device of this application can be used to execute the resource allocation indication method provided in this application. The resource allocation indication device provided in this application will be described below.

[0045] Figure 3 This is a schematic diagram of a resource allocation indication device according to an embodiment of this application. Figure 3 As shown, the device includes:

[0046] Broadcast unit 10 is used to broadcast transmission channel resource information to the target UE, wherein the number of hidden nodes existing within a preset range where the target UE is located meets a preset condition, and the transmission channel resource information is used to indicate the transmission channel resources for the target UE to receive data.

[0047] In the above-mentioned device, such as Figure 2As shown in the diagram, the aforementioned hidden nodes are illustrated. UE-1100, UE-2101, UE-3102, and UE-4103 are multiple UEs within the cell. UE-1100 can monitor the transmission channels of UE-2101 and UE-3102, while UE-3102 can monitor the transmission channels of UE-1100 and UE-4103. Therefore, there are hidden nodes between UE-2101 and UE-3102, and between UE-2101 and UE-4103; they cannot monitor each other's transmission channels. At a certain moment, UE-2101 transmits data to UE-1100 via channel A. Subsequently, UE-3102 also needs to transmit data (possibly to UE-1100 or UE-4103). However, because UE-3102 cannot detect the transmission channel A used by UE-2101, it may also select transmission channel A. In this situation, UE-1100 receives data from both UE-2101 and UE-3102 simultaneously on the same transmission channel A, resulting in a conflict and potentially preventing the correct demodulation of data sent by UE-2101. The aforementioned preset range is a preset distance from the target UE, and the preset condition is a preset number of hidden nodes. If all UEs broadcast their transmission channel resources for receiving data, it may consume a large amount of bandwidth. Therefore, this device only broadcasts its transmission channel resources for receiving data to UEs with a large number of hidden nodes in their vicinity—the target UE—to improve resource utilization. The aforementioned target UE determination mechanism can be performed periodically by the base station and indicated to the target UE via RRC (Radio Resource Control) signaling or MAC CE (Medium Access Control Control Element); alternatively, it can be performed periodically by the UE. Different determination periods can be configured based on the UE's movement speed within the cell. For example, a shorter determination period can be configured if the UE moves quickly within the cell, and a longer determination period can be configured if the UE moves slowly within the cell.

[0048] In this embodiment of the invention, the target UE is a UE whose number of hidden nodes within a preset range meets a preset condition. The target UE broadcasts transmission channel resource information, which in turn indicates the transmission channel resource for the target UE to receive data. This achieves the technical effect that other UEs communicating with the target UE do not use the transmission channel resource for data transmission, and solves the technical problem of resource conflict caused by different UEs selecting the same transmission resource due to hidden nodes.

[0049] In one embodiment of this application, the broadcast unit is further refined, specifically including a first determining module, a second determining module, and a third determining module. The first determining module is used to determine all UEs whose distance to the first UE is less than a first threshold as second UEs. The second determining module is used to determine the number of first combinations in which the distance between two second UEs is greater than a second threshold. The third determining module is used to determine the first UE as the target UE when the number of first combinations is greater than a third threshold. In the above device, the distribution of UEs in the cell varies, and can be concentrated or dispersed. The first UE can be the central UE among multiple UEs, or any UE among multiple UEs. The above device can quickly determine the location information of the first UE. Different first thresholds can be configured for different second UE transmission powers. By configuring different first thresholds for different transmission powers, the device can accurately obtain the actual coverage area of ​​the second UE and further accurately determine multiple second UEs around the first UE. In the above device, the second UE and its location information can be quickly determined based on the distance between the first UE and the second UE. Therefore, the above-mentioned device can quickly determine whether there is a hidden node in any two second UEs based on the location information of any two second UEs.

[0050] In another embodiment of this application, the first determining module is further refined. The first determining module includes a first determining submodule, used to determine the UE located at the center of a cluster as the first UE when the UEs in the cell are distributed in clusters. In practical applications, there may be a special scenario where the UEs in the cell are distributed in clusters, the relative distance between UEs in each cluster is relatively fixed, and there is a UE located at the center. This UE at the center can be determined as the first UE. After determining the first UE, the above-described device, because the UEs are distributed in clusters and the distance between UEs is fixed, can save on the device used for periodically determining the first UE, thus further saving energy consumption.

[0051] In another embodiment of this application, the first determining module is further refined. The first determining module includes a second determining submodule, used to determine a second combination in which the change in distance between two UEs within a preset time period is less than a fourth threshold; when the number of the second combinations containing the same UE is greater than a fifth threshold, the same UE is determined to be the first UE. The device can calculate the distance between any two UEs among multiple UEs at multiple times, where one distance corresponds to two UEs at one time, and multiple distances correspond to two UEs at multiple times; then calculate the mean and variance of the multiple distances corresponding to any two UEs to measure the change in distance. In the device, the number of times can be configured according to actual conditions. In the device, selecting a target UE through the UE's location information can reduce resource conflicts caused by a large number of hidden UE nodes, thus improving data transmission stability; when there are few hidden UE nodes in the cell, it reduces unnecessary transmission channel occupation, further improving resource utilization.

[0052] In one embodiment of this application, the broadcast unit is further refined, specifically including an acquisition module for the target UE to acquire the transmission channel resource information based on SCIs sent by other UEs. The SCIs are carried through the PSSCH or PSCCH channel. Adaptively and dynamically broadcasting its transmission channel resources for receiving data based on the monitoring results of the PSSCH and / or PSCCH channels can simultaneously address transmission channel load, UE energy saving, and transmission channel resource conflicts. This reduces the technical problem of resource conflicts arising from different UEs selecting the same transmission resources without exacerbating sidelink network congestion and while considering UE energy consumption.

[0053] In one embodiment of this application, the broadcast unit is further refined, specifically including a broadcast module used to broadcast the transmission channel resource information when the congestion level of the PSSCH channel or PSCCH channel is greater than a sixth threshold and less than a seventh threshold. In the above apparatus, to avoid congestion of transmission channel resources, the target UE can adaptively broadcast its transmission channel resources for receiving data based on the monitoring results of the PSSCH channel and / or PSCCH channel. When the CBR or CR is between the seventh threshold and the sixth threshold, the UE broadcasts its transmission channel resources for receiving data, avoiding resource conflicts.

[0054] In another embodiment of this application, the broadcast module is further refined, specifically including a third determining submodule, a first processing submodule, and a second processing submodule. The third determining submodule determines the congestion level of the PSSCH or PSCCH channel based on at least one of CBR and CR; and / or, the first processing submodule stops the target UE from broadcasting the transmission channel resource information when the congestion level is not greater than the sixth threshold; and / or, the second processing submodule stops the target UE from broadcasting the transmission channel resource information when the congestion level is not less than the seventh threshold. In the above apparatus, CBR is used to evaluate the portion of the resource pool where the RSSI (Received Signal Strength Indicator) exceeds a certain threshold within a given time period. CR is the total number of subchannels used by the UE for its transmission within a certain measurement period divided by the total number of configured subchannels. When the Channel Busy Ratio (CBR) is higher than the seventh threshold, it indicates that the sidelink network is congested. The UE can choose to stop broadcasting its transmission channel resources used for receiving data to reduce the occupation of transmission channel resources. When the CBR is lower than the sixth threshold, it indicates that the sidelink network is idle. At this time, the probability of resource collision is very low, and the UE can choose to stop broadcasting its transmission channel resources used for receiving data to save energy. When the Channel Busy Ratio (CR) is higher than the seventh threshold, it indicates that the sidelink network is congested. The UE can choose to stop broadcasting its transmission channel resources used for receiving data to reduce the occupation of transmission channel resources. When the CR is lower than the sixth threshold, it indicates that the sidelink network is idle. At this time, the probability of resource collision is very low, and the UE can choose to stop broadcasting its transmission channel resources used for receiving data to save energy.

[0059] In the aforementioned device, the current UE can learn that the transmission channel resource has been selected for use by receiving transmission channel resource information broadcast by other UEs, which indicates the transmission channel resource for receiving data.

The number of hidden nodes within a preset range where the target UE is located meets a preset condition. The transmission channel resource information is used to indicate the transmission channel resources for the target UE to receive data. The target UE is a UE whose number of hidden nodes within the preset range meets the preset condition. By broadcasting the transmission channel resource information to the target UE, the transmission channel resource information indicates the transmission channel resources for the target UE to receive data. This achieves the technical effect that other UEs communicating with the target UE do not use the same transmission channel resources for data transmission, solving the technical problem of resource conflicts caused by different UEs selecting the same transmission resources due to hidden nodes.

[0075] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
