Description

[0001] This application claims priority to PCT patent application filed with the China Patent Office on September 28, 2017, with application number PCT / CN2017 / 104018 and application name “Method, network device and communication device for resource allocation”, the entire contents of which are incorporated by reference in this application. Technical Field

[0002] The present application relates to the field of communications, and in particular to a method, a network device and a communication device for resource allocation. Background Art

[0003] The Internet of Vehicles system is a sidelink (SL) transmission technology based on long term evolution (LTE) device-to-device communication (D2D). Unlike the traditional LTE system in which communication data is received or sent by base stations, the Internet of Vehicles system adopts direct communication from terminal device to terminal device, so it has higher spectrum efficiency and lower transmission delay.

[0004] In the Rel-14 version of the 3rd Generation Partnership Project (3GPP), the vehicle-to-everything (V2X) technology was standardized, and two transmission modes were defined: Mode 3 and Mode 4. In Mode 3, the transmission resources of the vehicle terminal are allocated by the base station, and the vehicle terminal sends data on the sidelink according to the resources allocated by the base station; the base station can allocate resources for a single transmission to the terminal, or it can allocate resources for semi-static transmission to the terminal. Mode 4: The vehicle terminal adopts the transmission mode of sensing and reservation. The vehicle terminal obtains the available transmission resource set in the resource pool by sensing, and then randomly selects a resource from the set for data transmission. Since the services in the vehicle-to-everything system have periodic characteristics, the vehicle terminal usually adopts the semi-static transmission mode, that is, after the terminal selects a transmission resource, it will continue to use the resource in multiple transmission cycles, thereby reducing the probability of resource reselection and resource conflict.

[0005] In addition, the terminal device can transmit data through carrier aggregation (CA), but in order to prevent the terminal device from abusing carrier resources, it is necessary to impose appropriate restrictions on the carrier selection behavior of the terminal device. However, for mode 3, the network device cannot implement such restrictions. Summary of the invention

[0069] Figure 1 FIG. 1 is a schematic flow chart of a method 100 for resource allocation according to an embodiment of the present application. The method 100 may be executed by a network device. Figure 1 As shown, the method 100 includes: S110, determining the QoS attribute of the first terminal device; S120, allocating transmission resources to the first terminal device according to the QoS attribute, and the transmission resources are used for the first terminal device to send data to the second terminal device.

[0070] In an embodiment of the present application, the network device determines the QoS attributes of the first terminal device, which may include: the network device receives QoS attribute information sent by the first terminal device or a core network element, and indicates the QoS attributes of the first terminal device through the QoS attribute information.

[0071] It should be understood that the QoS attributes of the first terminal device may include the data transmission rate and / or reliability requirements of the first terminal device, or may also include other parameters characterizing the QoS attributes of the first terminal device, and the embodiments of the present application are not limited to this.

[0072] Specifically, the QoS attributes of the first terminal device may include the data transmission rate and / or reliability requirements of the target service, or may also include other parameters characterizing the QoS attributes of the target, wherein the target service is the service between the first terminal device and the second terminal device, and the first terminal device can transmit the target service to the second terminal device through the transmission resources configured by the network device.

[0073] Correspondingly, the QoS attribute information may include information related to the data transmission rate of the target service of the first terminal device or the first terminal device and the second terminal device, and / or may also include information related to reliability requirements, or may also include information characterizing other QoS attributes. For ease of explanation, the following is an example in which the QoS attribute information includes information related to data transmission rate and / or reliability requirements.

[0074] Optionally, as an embodiment, the QoS attribute information may include a specific value indicating a data transmission rate and / or reliability requirement. For example, the QoS attribute information may include a specific value indicating a data transmission rate, such as any three data transmission rates may be defined, namely X / Y / Z (Mbit / s), and the QoS attribute information includes any one of the three data transmission rate values.

[0075] For another example, the QoS attribute information may also include specific values ​​representing reliability requirements. For example, the reliability requirements may be represented by the packet loss rate. Three packet loss rates (error rate) may be arbitrarily defined, namely 10^-A / 10^-B / 10^-C. The QoS attribute information may include any one of the three values.

[0076] Optionally, as an embodiment, the QoS attribute information may also include a maximum value and / or a minimum value representing the data transmission rate and / or reliability requirement when transmitting the target service between the first terminal device or the first terminal device and the second terminal device. Specifically, the QoS attribute information may include a maximum value, which is the maximum value of the data transmission rate and / or reliability requirement, that is, the network device can determine, based on the QoS attribute information, that the data transmission rate and / or reliability requirement of the first terminal device or the target service in the corresponding QoS attribute does not exceed the maximum value.

[0077] Alternatively, the QoS attribute information may include a minimum value, which is the minimum value of the data transmission rate and / or reliability requirement, that is, the network device can determine, based on the QoS attribute information, that the data transmission rate and / or reliability requirement of the first terminal device or target service in the corresponding QoS attribute is not lower than the minimum value.

[0078] Alternatively, the QoS attribute information may also include an interval value, which corresponds to a maximum value and a minimum value, that is, the QoS attribute information may also include a range, and the data transmission rate and / or reliability requirement of the first terminal device or the target service does not exceed the upper limit of the interval value, and the data transmission rate and / or reliability requirement of the first terminal device or the target service is not lower than the lower limit of the interval value, that is, the network device can determine, based on the QoS attribute information, that the range of the data transmission rate and / or reliability requirement of the first terminal device or the target service in the corresponding QoS attribute is within the interval value.

[0079] Optionally, as an embodiment, before the network device receives the QoS attribute information sent by the first terminal device or the core network network element, the method 100 also includes: the network device sends a preset value to the first terminal device or the core network device, so that the first terminal device or the core network device that receives the preset value sends the QoS attribute information according to the preset value.

[0080] Among them, the QoS attribute information may include the relationship between the data transmission rate and / or reliability requirement of the target service or the first terminal device and the preset value, and the relationship may be any one of the following four relationships: the data transmission rate and / or reliability requirement of the target service or the first terminal device is greater than the preset value, the data transmission rate and / or reliability requirement of the target service or the first terminal device is less than the preset value, the data transmission rate and / or reliability requirement of the target service or the first terminal device is greater than or equal to the preset value, and the data transmission rate and / or reliability requirement of the target service or the first terminal device is less than or equal to the preset value.

[0081] Optionally, as an embodiment, the QoS attribute may also be represented by an index. Specifically, a mapping relationship between multiple QoS attributes and different indexes may be established, such as a mapping relationship between different data transmission rates and reliability requirements and different indexes. The QoS attribute information may include a target index, and the network device determines, based on the mapping relationship, that the QoS attribute corresponding to the target index is the QoS attribute of the first terminal device.

[0082] For example, any three data transmission rates are defined as X / Y / Z (Mbit / s) respectively. Similarly, the reliability requirement can be quantified by the packet loss rate, and three packet loss rates are defined as 10^-A / 10^-B / 10^-C respectively. There are 3*3=9 combinations of the three data transmission rates and the three packet loss rates. An index can be defined for each of the 9 combinations, and a mapping relationship between the 9 combinations and the 9 different indexes is established. The network device determines that the QoS attribute information includes a target index, and the target index can be any one of the 9 indexes. The combination of the data transmission rate and the packet loss rate corresponding to the target index is determined as the QoS attribute of the first terminal device.

[0083] For another example, for the 9 combinations of the three data transmission rates and the three packet loss rates, after excluding some of the 9 combinations, an index is defined for each remaining combination, and a mapping relationship between the remaining combinations and different indexes is established. The embodiments of the present application are not limited to this.

[0084] In an embodiment of the present application, a network device determines a QoS attribute of the first terminal device, and allocates transmission resources to the first terminal device according to the QoS attribute, wherein the transmission resources include carrier resources, and one or more component carriers may be allocated to the first terminal device, so that the first terminal device may use the transmission resources to send data to a second terminal device, wherein the second terminal device may be a terminal device other than the first terminal device. The first terminal device may use the transmission resources to send data to a plurality of terminal devices, and the second terminal device may be any one of the plurality of terminal devices.

[0085] Therefore, in the method for resource allocation in an embodiment of the present application, a network device can determine the QoS attributes of a terminal device and allocate transmission resources, such as carrier resources, to the terminal device based on the QoS attributes, so that the terminal device can use the transmission resources to send data to other terminal devices, thereby improving resource utilization.

[0086] Figure 2 A schematic flow chart of a method 200 for resource allocation according to an embodiment of the present application is shown. The method 200 may be executed by a communication device.
