Description

Resource scheduling method, terminal equipment and network equipment

Technical Field

The present application relates to the field of communications, and in particular, to a resource scheduling method, a terminal device, and a network device.

Background

The car networking system is based on a Long Term Evolution (LTE) terminal-to-terminal (D2D) Sidelink (SL) transmission technology, and is different from a mode in which communication data is received or transmitted by a base station in a conventional LTE system, and the car networking system adopts a mode in which terminal-to-terminal direct communication is adopted, so that the car networking system has higher spectral efficiency and lower transmission delay.

The technology of car networking is standardized in Release14(Rel-14) of the third Generation Partnership Project (3 GPP), including the definition of two transmission modes: mode 3(mode3) and mode 4(mode 4). In mode3, the transmission resource of the vehicle-mounted terminal is allocated by the base station, and the vehicle-mounted terminal transmits data with other vehicle-mounted terminals on a sidelink according to the resource allocated by the base station; moreover, the base station may allocate resources for single transmission to the terminal, or may allocate resources for semi-static transmission to the terminal.

In the mode4, the in-vehicle terminal adopts a transmission mode combining listening (sending) and reservation (reservation). The vehicle-mounted terminal acquires an available transmission resource set in the resource pool in an intercepting mode, and randomly selects one resource from the set to transmit data. Because the service in the car networking system has a periodic characteristic, the terminal generally adopts a semi-static transmission mode, that is, after the terminal selects one transmission resource, the resource is continuously used in a plurality of transmission cycles, so that the probability of resource reselection and resource conflict is reduced.

In the existing car networking system, the resource of mode3 is scheduled by a 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 that the two resource pools do not overlap.

However, in the new version, terminal devices in mode3 and mode4 may share a resource pool and may coexist with terminal devices operating based on version Rel-14, while some of the terminal devices in version Rel-14 do not have a listening function, thus causing resource conflicts between some of the terminal devices.

Detailed Description

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 of the embodiments of the present application may be applied to various communication systems, for example: an LTE system, an LTE Frequency Division Duplex (FDD) system, an LTE Time Division Duplex (TDD), a 4.5(4.5th generation, 4.5G) generation network, a fifth generation (5th generation, 5G) network, a New Radio (NR), and the like. The embodiment of the application can also be applied to a vehicle to other equipment (V2X) system, such as a vehicle to vehicle (V2V) system; alternatively, the present invention may also be applied to a device to device (D2D) system, and the embodiments of the present application are not limited thereto.

It should be understood that the network device according to 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 macro base stations, micro base stations, relay stations, access points, and the like. In systems employing different radio access technologies, the names of devices having a base station function may differ. For example, in an LTE network, referred to as an evolved node B (eNB or eNodeB), in a third Generation (3rd Generation, 3G) network, referred to as a node B (node B), and so on.

It should be understood that the Terminal device in the embodiment of the present application may also be referred to as a Terminal (Terminal), a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), or the like. The terminal device may be a Vehicle User Equipment (VUE), for example, a wireless terminal in a vehicle or a self driving (self driving), or the like; alternatively, the terminal device may also be a pedestrian handheld terminal (PUE), such as a mobile phone (mobile phone), a tablet computer (Pad), a computer with a wireless transceiving function, and the like.

FIG. 1 shows a schematic diagram of a vehicle networking system according to an embodiment of the application. As shown in fig. 1, the embodiment of the present application may be applied to various application scenarios, where a network device and a terminal device in a car networking system are taken as examples for description, where the network device may be a base station (eNB), and the terminal device may be a vehicle-mounted terminal, and the vehicle-mounted terminal includes a vehicle 1 and a vehicle 2.

The technology of car networking is standardized in release Rel-14 of 3GPP, including the definition of two transmission modes: mode3 and mode 4. In mode3, the transmission resource of the vehicle-mounted terminal is allocated by the base station, and the vehicle-mounted terminal transmits data with other vehicle-mounted terminals on a sidelink according to the resource allocated by the base station; moreover, the base station may allocate resources for single transmission to the terminal, or may allocate resources for semi-static transmission to the terminal.

For example, as shown in fig. 1, the eNB may configure the vehicle 1 with the granted resource, and may transmit resource grant information indicating the granted resource through a Downlink (DL) as in fig. 1. The vehicle 1 determines the authorized resource and uses the authorized resource to send data to the vehicle 2 over the SL. Alternatively, the eNB may configure the vehicle 2 with the granted resource through DL, and the vehicle 2 transmits data to the vehicle 1 through SL using the granted resource.

For example, as shown in fig. 1, if the vehicle 1 in mode4 transmits data to the vehicle 2, the vehicle 1 may listen without going through the eNB, acquire available resources, and transmit data to the vehicle 2 through the SL using the available resources.

In the car networking system, two types of terminal devices are generally mainly considered: VUE and PUE. Among them, the VUE generally has higher processing capability and is usually powered by a storage battery in the vehicle, while the PUE processing capability is lower, and reducing power consumption is also a main factor to be considered by the PUE, so in the existing vehicle networking system, the VUE is considered to have complete receiving capability and listening capability; while PUEs are considered to have partial or no receiving and listening capabilities. If the PUE has partial interception capability, the resources can be selected by adopting an interception method similar to that of the VUE, and available resources can be selected on the intercepted partial resources; and if the PUE does not have the interception capability, the PUE randomly selects transmission resources in the resource pool.

In addition, in the existing version Rel-14 of the car networking 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 that the two do not have the condition of overlapping resource pools.

While in the new version, terminal devices at mode3 and mode4 may share a resource pool, for example, with a terminal device at mode3 based on version Rel-14, or with a terminal device at mode4 based on version Rel-14. Since the terminal of mode3 is connected to the base station and its transmission resources are allocated by the base station, it is more desirable to protect the transmission reliability of mode3 terminals when mode3 and mode4 coexist.

Thus, for the case where the resource pool is shared and there are terminal devices in mode3 in various versions, the scenario that protects the transmission reliability of mode3 terminals can be considered primarily.

Scene one: a terminal device in mode3 based on version Rel-14 coexists with a terminal device in mode3 in a new version. Since the terminal device of the Rel-14mode3 does not listen to the resource, the terminal device of the new version mode4 is required to listen, but in the process that the terminal device of the new version mode4 already selects the resource and semi-statically transmits, it is still possible that the resource is allocated to the terminal device of the Rel-14mode3, because the base station does not know the resource usage of the resource pool of the Rel-14mode3, the terminal device of the new version mode4 is required to listen to the resource in the transmission process, for example, the terminal device of the new version mode4 adopts a muted (silent) mode at some transmission time, that is, does not send data in the transmission, but only listens and receives, so as to determine whether other terminal devices occupy the resource, if so, the terminal device of the new version mode4 performs resource reselection to avoid interference.

Scene two: in the case where terminal devices of the new versions of mode4 and mode3 share a resource pool, since both terminal devices are terminals of the new versions, the resource pool sharing thereof can be easily achieved. For example, mode indication information is added to the control information of mode3 to indicate that the transmission is a mode3 type transmission, and the terminal of mode4 detects the information to avoid selecting the resources occupied by the user, thereby avoiding interference to the mode3 user.

Scene three: in the case that a new version of the mode3 and a terminal device in the mode4 based on the version Rel-14 share a resource pool, because the terminal device in the mode4 of the version Rel-14 can listen to the terminal device in the same version but cannot listen to the terminal device in the new version, and the terminal device in the new version of the mode3 is allocated with resources by a base station, the base station cannot know the transmission resources of the terminal device in the mode4 of the Rel-14, which would cause resource collision, the embodiment of the present application provides a method for scheduling resources, which can avoid or reduce resource collision in the scenario.

Fig. 2 shows a schematic flow chart of a method 100 of resource scheduling according to an embodiment of the present application, where the method 100 may be performed by a terminal device, for example, a vehicle-mounted terminal as shown in fig. 1, where the vehicle-mounted terminal may be the vehicle 1 or the vehicle 2 in fig. 1.

Specifically, as shown in fig. 2, the method 100 includes: s110, a first terminal device in a first mode receives indication information sent by a network device, wherein the first terminal device in the first mode is a terminal device which acquires transmission resources in a corresponding resource pool through configuration of the network device; s120, the first terminal device in the first mode determines whether to monitor the transmission resource occupied by a second terminal device in the resource pool according to the indication information, where the second terminal device is another terminal device except the first terminal device in the terminal devices corresponding to the resource pool.

It should be understood that the first terminal device may be any terminal device, and the first terminal device performs data transmission through the transmission resource configured by the network device when the first terminal device is in the first mode, and the first terminal device may support listening and may listen to the transmission resource of other terminal devices in the resource pool corresponding to the first terminal device. For example, the first terminal device may operate based on a new version, and the first mode may refer to mode3, 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 or may not support listening or have partial listening capabilities, e.g. only support listening to terminal devices of the same type. The second terminal device may be in a second mode, and 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, and perform data transmission through the network device configuration resource.

In this embodiment of the present application, because when the first terminal device and the second terminal device are both in the first mode, the network device may determine resources respectively occupied by the first terminal device and the second terminal device, and the first terminal device and the second terminal device may not perform listening, in this 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 various terminal devices based on the same version, for example, both based on a new version; alternatively, the first terminal device and the second terminal device may also operate based on different versions, for example, the first terminal device may operate based on a new version, and the second terminal device may operate based on the version Rel-14, so that the second terminal device cannot listen to or identify the terminal device operating based on the new version, but may identify the terminal device of the same version.

In this embodiment, a first terminal device in a first mode may configure a transmission resource through a network device, and before configuration, the network device may determine whether a second terminal device exists in a resource pool corresponding to the first terminal device in the first mode, and send 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 a second terminal device in the second mode still exists in a resource pool corresponding to the first terminal device in the first mode, the network device may send indication information to the first terminal device in the first mode, 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, according to the indication information, that the second terminal device in the second mode needs to be listened to in the resource pool.

Optionally, as an embodiment, when the network device determines that there is no second terminal device in the second mode in the resource pool corresponding to the first terminal device in the first mode, the network device may send indication information to the first terminal device in the first mode, where the indication information is used to indicate that there is no second terminal device in the second mode in the resource pool, and the first terminal device in the first mode may determine, according to the indication information, that it is not necessary to listen to the second terminal device in the second mode in the resource pool.

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

Optionally, as an embodiment, when the network device determines that there is no second terminal device in the second mode in the resource pool corresponding to the first terminal device in the first mode, the network device may further determine that the first terminal device in the first mode does not need to perform listening in the resource pool, and then the network device sends indication information to the first terminal device in the first mode, where the indication information indicates that the first terminal device in the first mode does not need to perform listening.

It is to be understood that when the first terminal device in the first mode determines to perform listening, listening is performed in the resource pool in which the first terminal device in the first mode may listen to transmission resources occupied by the second terminal device in the second mode. Specifically, for the terminal device to be intercepted 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 terminal device to be intercepted is the second terminal device in the second mode, if so, the interception is performed, and if not, the interception may not be performed.

For example, the first terminal device in the first mode may determine whether a second terminal device in the second mode exists according to the relevant bit indication in the control channel. For example, the second terminal device in the second mode is a terminal device of mode4 operating based on version Rel-14, and for any terminal device to be listened to, the first terminal device may determine, according to the relevant bits, whether the terminal device to be listened to is in mode3 or mode4, and if the terminal device to be listened to is in mode4, it continues to determine whether the terminal device to be listened to is operating based on version Rel-14, thereby determining whether the terminal device to be listened to is a second terminal device in the second mode.

In this 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 a listening result to the network device, the network device allocates the transmission resource to the first terminal device in the first mode according to the listening result, and the transmission resource allocated to the first terminal device in the first mode is the resource other than the transmission resource occupied by the second terminal device in the second mode in the resource pool, so that resource conflict can be avoided.
