Description

Resource scheduling method, terminal device and network device Technical field

Background technique

In the traditional LTE system, communication data is received through the base station. Or the way of sending is different. The car networking system adopts the method of direct communication from the terminal to the terminal, so it has higher spectral efficiency and lower transmission delay.

The car networking technology was standardized in Release 3 (Rel-14) of the 3rd Generation Partnership Project (3GPP), including two transmission modes defined: mode 3 (mode 3) and mode 4 (mode 4 ).

Resources can also allocate semi-statically transmitted resources to terminals.

In addition, in mode 4, the in-vehicle terminal adopts a transmission mode in which sensing and reservation are combined. The vehicle terminal obtains a set of available transmission resources by means of interception in the resource pool, and the vehicle terminal randomly selects one resource from the set for data transmission. Since the service in the car network system has periodic characteristics, the terminal usually adopts a semi-static transmission mode, that is, after the terminal selects one transmission resource, the terminal continuously uses the resource in multiple transmission cycles, thereby reducing resource reselection and The probability of a resource conflict.

In the existing car network system, the resources of mode3 are scheduled by the base station, the resource pool of mode4 is pre-configured or configured by the base station, and the resource pools of mode3 and mode4 are separated or orthogonal, so there is no resource in the two. The situation of pool overlap.

Therefore, it will cause resource conflicts between some terminal devices.

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

It should be understood that the technical solutions in the embodiments of the present application may be applied to various communication systems, such as an LTE system, an LTE frequency division duplex (FDD) system, and an LTE time division duplex (TDD). 4.5 (4.5th generation, 4.5G) generation network, fifth generation (5th generation, 5G) network, new radio (NR), etc. The embodiment of the present application can also be applied to a vehicle to everything (V2X) system, such as a vehicle to vehicle (V2V) system; or, In the device to device (D2D) system, the embodiment of the present application is not limited thereto.

It should be understood that the network device involved in the embodiments of the present application is a device deployed in a radio access network to provide a wireless communication function for a terminal device. The network device may be a base station, and the base station may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems with different radio access technologies, the names of devices with base station functionality may vary. For example, in an LTE network, an evolved Node B (eNB or eNodeB) is called a Node B or the like in a 3rd Generation (3G) network.

It should be understood that the terminal device in the embodiment of the present application may also be referred to as a terminal, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), and the like. The terminal device may be a vehicle user equipment (VUE), for example, a wireless terminal in a vehicle or a self driving, or the like; or the terminal device may also be a pedestrian user equipment (PUE). For example, a mobile phone, a tablet, a computer with a wireless transceiver, and the like.

FIG. 1 shows a schematic diagram of a car networking system in accordance with an embodiment of the present application. As shown in FIG. 1 , the embodiment of the present application can be applied to various application scenarios. The network device and the terminal device in the vehicle networking system are used as an example. The network device may be a base station (eNB), and the terminal device may be An in-vehicle terminal including a vehicle 1 and a vehicle 2.

The car networking technology has been standardized in the 3GPP version of Rel-14, including two transmission modes defined: mode3 and mode4. Wherein, in mode3, the transmission resource of the in-vehicle terminal is allocated by the base station, and the in-vehicle terminal transmits data to the other in-vehicle terminal on the side line according to the resource allocated by the base station; and the base station can allocate a single transmission to the terminal. Resources can also allocate semi-statically transmitted resources to terminals.

For example, as shown in FIG. 1 , the eNB may configure an authorization resource for the vehicle 1 , and may send resource authorization information indicating the authorized resource by using a downlink (DL) as in FIG. 1 . The vehicle 1 determines the authorized resource and transmits the data to the vehicle 2 through the SL using the authorized resource. Alternatively, the eNB may also configure the vehicle 2 with an authorized resource through the DL, and the vehicle 2 uses the authorized resource to transmit data to the vehicle 1 through the SL.

In addition, in mode 4, the in-vehicle terminal adopts a transmission mode in which sensing and reservation are combined. The vehicle terminal obtains a set of available transmission resources by means of interception in the resource pool, and the vehicle terminal randomly selects one resource from the set for data transmission. Since the services in the Internet of Vehicles system have periodic characteristics, the terminal usually adopts a semi-static transmission method, that is, the terminal After selecting a transmission resource, the resource will continue to be used in multiple transmission cycles, thereby reducing the probability of resource reselection and resource conflict.

For example, as shown in FIG. 1, if the vehicle 1 in mode 4 transmits data to the vehicle 2, it may listen to the vehicle 1 without acquiring an available resource, acquire available resources, and transmit data to the vehicle 2 through the SL using the available resources. .

In the Internet of Vehicles system, two types of terminal devices are generally considered: VUE and PUE. Among them, VUE generally has higher processing capacity, and is usually powered by the battery in the car, and the PUE processing power is lower, and reducing power consumption is also a major factor that PUE needs to consider, so in the existing car network system, VUE It is considered to have full reception and listening capabilities; while PUE is considered to have partial or no reception and listening capabilities. If the PUE has partial interception capability, the resource may be selected by using a similar listening method as the VUE, and the available resources may be selected on some resources that can be intercepted; if the PUE does not have the listening capability, the PUE is in the resource pool. Randomly select transmission resources.

In addition, in the existing version of the car networking system Rel-14, the resources of mode3 are scheduled by the base station, the resource pool of mode4 is pre-configured or configured by the base station, and the resource pools of mode3 and mode4 are separated or orthogonal. Therefore, there will be no overlap of resource pools.

In the new version, the terminal devices in mode3 and mode4 may share the resource pool. For example, the resource pool may be shared with the terminal device based on the version Rel-14 based on the version Rel-14, or may be in the mode4 with the version based on the version Rel-14. The terminal device shares the resource pool. Since the terminal of mode3 is connected to the base station, and its transmission resource is allocated by the base station, when mode3 and mode4 coexist, it is more necessary to protect the transmission reliability of the mode3 terminal.

Therefore, for a shared resource pool, and there are terminal devices in mode 3 in various versions, the following scenarios can be considered to protect the transmission reliability of the mode3 terminal.

Scenario 1: The terminal device in mode 3 based on the version Rel-14 coexists with the terminal device in mode3 in the new version. Since the terminal device of Rel-14mode3 does not listen to resources, the terminal device of the new version of mode4 is required to listen, but in the process that the terminal device of the new version mode4 has selected resources and semi-static transmission, it is still possible that the resource is The terminal device assigned to Rel-14mode3, because the base station does not know the resource usage of the Rel-14 mode3 resource pool, so the terminal device of the new version mode4 needs to listen for resources during the transmission process, such as the terminal device of the new version mode4. In some transmission moments, the muting method is adopted, that is, no data is transmitted in the transmission, and only listening and receiving are performed, thereby judging whether there are other terminals on the resource. The device is occupied, and if so, the terminal device of the new version mode4 performs resource reselection to avoid interference.

Scenario 2: The new version of the mode4 and mode3 terminal devices share the resource pool. Since both terminal devices are new versions of the terminal, the resource pool sharing can be easily realized. For example, the mode indication information is added to the control information of the mode3 to indicate that the transmission is a mode3 type transmission, and the terminal of the mode4 detects the information to avoid selecting resources occupied by the user, thereby avoiding interference to the mode3 user.

Scenario 3: The new version of mode3 and the version of the Rel-14-based terminal device share the resource pool. The version of the Rel-14 terminal device in mode4 can listen to the same version of the terminal device, but cannot listen to the new device. The terminal device in the version, and the terminal device of the new version of mode3 is allocated resources by the base station, and the base station cannot know the transmission resource of the terminal device of the mode 4 of the Rel-14, which will cause a resource conflict. Therefore, the embodiment of the present application proposes a A resource scheduling method can avoid or reduce resource conflicts in the scenario.

FIG. 2 shows a schematic flowchart of a method 100 for resource scheduling according to an embodiment of the present application. The method 100 may be performed by a terminal device, for example, may be performed by an in-vehicle terminal as shown in FIG. Vehicle 1 or vehicle 2 in 1.

Obtaining, by the first terminal device in the first mode, the first terminal device in the first mode, according to the indication information, whether to listen to the transmission resource occupied by the second terminal device in the resource pool, where The second terminal device is a terminal device other than the first terminal device in the terminal device corresponding to the resource pool.

It should be understood that the first terminal device may be any terminal device, and when the first terminal device is in the first mode, data transmission is performed by using a transmission resource configured by the network device, and the first terminal device may support listening, and may listen to the first terminal device. A transmission resource of another terminal device in a resource pool corresponding to a terminal device. For example, the first terminal device may work based on a new version, and the first mode may refer to mode 3, but the embodiment of the present application is not limited thereto.

It should be understood that the second terminal device may be any terminal device, and the second terminal device corresponds to the same resource pool as the first terminal device. The second terminal device may support listening, or may not support listening, or have partial listening capability, for example, only support listening to the same type of terminal device. The second terminal device may be in the second mode, where the second terminal device in the second mode may acquire the transmission resource by listening; or the second terminal device may also be in the first mode. The network device configures resources for data transmission.

In the embodiment of the present application, when the first terminal device and the second terminal device are in the first mode, and the network device can determine the resources occupied by the first terminal device and the second device device respectively, the first terminal device and the first terminal device The second terminal device may not perform the interception. Therefore, in the embodiment of the present application, the first terminal device is in the first mode, and the second terminal device is in the second mode. The first terminal device and the second terminal device may be terminal devices based on different versions of the same version, for example, all based on a new version; or the first terminal device and the second terminal device may also work based on different versions, for example, The first terminal device can work based on the new version, and the second terminal device can be based on the version Rel-14, the second terminal device cannot listen or recognize the terminal device working based on the new version, but can identify the terminal device of the same version. .

In the embodiment of the present application, the first terminal device in the first mode may configure the transmission resource by using the network device, and before the configuration, the network device may determine whether the resource pool corresponding to the first terminal device in the first mode exists. The second terminal device sends the indication information to the first terminal device in the first mode, so that the first terminal device in the first mode determines whether to listen to other terminal devices in the corresponding resource pool according to the indication information. .

Optionally, as an embodiment, when the network device determines that the second terminal device in the second mode exists in the resource pool corresponding to the first terminal device in the first mode, the network device may be in the first mode. The first terminal device sends the indication information, where the indication information is used to indicate that the second terminal device in the second mode exists in the resource pool, and the first terminal device in the first mode may determine that the resource is needed according to the indication information. The pool is listening to the second terminal device in the second mode.

Optionally, as an embodiment, when the network device determines that the second terminal device in the second mode does not exist in the resource pool corresponding to the first terminal device in the first mode, the network device may be in the first mode. The first terminal device sends the indication information, where the indication information is used to indicate that the second terminal device in the second mode does not exist in the resource pool, and the first terminal device in the first mode may determine, according to the indication information, that the The resource pool is listening to the second terminal device in the second mode.

Optionally, as an embodiment, when the network device determines that the second terminal device in the second mode exists in the resource pool corresponding to the first terminal device in the first mode, the network device may further determine that the device is in the first The first terminal device in a mode needs to perform the interception in the resource pool, and the network device sends the indication information to the first terminal device in the first mode, where the indication information indicates The first terminal device in the first mode performs interception.

Optionally, as an embodiment, when the network device determines that the second terminal device in the second mode does not exist in the resource pool corresponding to the first terminal device in the first mode, the network device may further determine that the device is in the first The first terminal device of the mode does not need to perform the interception in the resource pool, and the network device sends the indication information to the first terminal device in the first mode, where the indication information indicates the first terminal device in the first mode. No snooping is required.

It should be understood that when the first terminal device in the first mode determines to perform the interception, the interception is performed in the resource pool, and the first terminal device in the first mode may listen in the resource pool in the second mode. The transmission resource occupied by the second terminal device. Specifically, for the to-be-listened terminal device in the resource pool corresponding to the first terminal device in the first mode, the first terminal device in the first mode may determine whether the to-be-listened device is in the second mode. The second terminal device, if yes, listens, if not, it may not listen.

For example, the first terminal device in the first mode may determine whether there is a second terminal device in the second mode according to the relevant bit indication in the control channel. For example, the second terminal device in the second mode is the terminal device of the mode 4 working on the version Rel-14. For any device to be intercepted, the first terminal device can determine the to-be-listened terminal device according to the relevant bit. Whether it is in mode3 or mode4, if it is in mode4, it continues to determine whether it is working based on the version Rel-14, thereby determining whether the device to be monitored is the second terminal device in the second mode.

In the embodiment of the present application, the first terminal device in the first mode listens to the transmission resource occupied by the first terminal device in the first mode in the corresponding resource pool, and sends the interception result to the network device, where the network device is configured according to the network device. The interception result is that the first terminal device in the first mode is allocated a transmission resource, and the transmission resource allocated to the first terminal device in the first mode is occupied by the second terminal device in the resource pool in the second mode. Transfer resources other than resources to avoid resource conflicts.
