Description

Resource selection method and device, computer readable storage medium, and terminal

This application claims priority to a Chinese patent application filed with the China Patent Office on November 15, 2022, with application number 202211428199.9 and invention name “Resource selection method and device, computer-readable storage medium, terminal”, the entire contents of which are incorporated by reference in this application.

Technical Field

The present application relates to the field of communication technology, and in particular to a resource selection method and device, a computer-readable storage medium, and a terminal.

Background technique

Sidelink (SL) is a communication technology that is different from traditional cellular network communication. Referring to FIG1 , FIG1 is a schematic diagram of uplink and downlink and sidelink. As shown in FIG1 , in a traditional cellular network, a terminal (such as terminal 1) and a network device (for example, a base station) communicate, and the link between the terminal and the network device is called an uplink (UL) link or a downlink (DL), and the interface is called a Uu interface.

In SL communication technology, terminal 1 communicates directly with terminal 2, and the link between the terminals is a direct link, also called a through link, side link, side link, direct link, auxiliary link or PC5 link, etc. The interface is called a PC5 interface.

There are currently two main modes for allocating transmission resources on a direct link: mode 1 (mode 1) and mode 2 (mode 2).

Mode 1 is a scheduled resource allocation method. Specifically, in Mode 1, the network device sends a dedicated signaling to the transmitter UE (Tx UE) through the downlink to configure a direct link for the Tx UE. More specifically, the network device can schedule the transmission resources of the direct link for the Tx UE through RRC signaling or downlink control information (Downlink Control Information, referred to as DCI). After the Tx UE receives the scheduled resources, it can send data to the receiving terminal (Receiver UE, referred to as Rx UE) through the PC5 interface.

Mode 2 is an autonomous resource selection method, where the Tx UE can autonomously select transmission resources on the direct link from the resource pool in a perceptual manner. The resource pool can be configured by the network device. Alternatively, the resource pool can be preset by the protocol.

When the sidelink operates in the millimeter wave frequency band (frequency range 2, abbreviated as FR2) between 24.25 GHz and 52.6 GHz, due to the large path loss of the millimeter wave, if the resources selected based on the existing resource selection method are used for data transmission on the direct link, data transmission failure may still occur. The existing resource selection method still needs to be optimized.

Detailed ways

As described in the background art, when using resources selected based on existing resource selection methods to perform data transmission on a direct link, data transmission failure may still occur, and the existing resource selection methods still need to be optimized.

In the New Radio (NR) system, a beam forming mechanism is introduced to overcome the problem of easy fading caused by high frequency. For the transmitting device, the transmitting antenna no longer transmits omnidirectionally, but through the antenna design, the transmitting antenna only covers a certain direction within a specific time, and then performs spatial coverage through beam scanning (that is, the process of adjusting the antenna transmission direction). For the receiving device, the receiving antenna also only receives in a specific direction within a specific time, and the receiving device completes the receiving coverage through beam scanning.

The beam is reflected in the NR protocol as a spatial filter parameter, which can also be called a spatial domain filter parameter (spatial domain filter parameter), or a spatial filter parameter, or a spatial parameter (spatial parameter).

Among them, the beam used to send signals is a transmission beam (Tx beam for short), which can also be called a spatial domain transmission filter parameter (spatial domain transmission filter parameter) or a spatial transmission parameter (spatial transmission parameter). The beam used to receive signals is a reception beam (Rx beam for short), which can also be called a spatial domain receive filter parameter (spatial domain receive filter parameter) or a spatial receive parameter (spatial RX parameter).

When the sidelink works in FR2, due to the large path loss of millimeter waves, beams need to be used for transmission to allow the signal to form gain in one direction and zero drop in other directions. For a specific Rx UE, the Tx UE needs to use a specific beam to achieve effective data transmission with the Rx UE.

Refer to Figure 2, which is a schematic diagram of an application scenario of a resource selection method in an embodiment of the present application.

As shown in FIG2 , through beam training, terminal 1 can determine that beam 1 is used for communication with terminal 2, and beam 2 is used for communication with terminal 3. Thus, terminal 1 can use beam 1 to send data to terminal 2, and terminal 2 can use the beam aligned with beam 1 to receive data sent by terminal 1. Terminal 1 can also use beam 2 to send data to terminal 3, and terminal 3 can use the beam aligned with beam 2 to receive data sent by terminal 1.

However, if the beam of the resource selected by terminal 1 is beam 3, the beam direction of beam 3 is different from the beam direction of beam 1 and the beam direction of beam 2, and if terminal 1 sends data using beam 3, data transmission fails. More specifically, if terminal 1 sends data using beam 3, terminal 2 cannot receive the data sent by terminal 1, and terminal 3 cannot receive the data sent by terminal 1.

In view of this, an embodiment of the present application provides a resource selection method. In the solution of the embodiment of the present application, it is determined whether the beam of the resource includes the beam associated with the receiving device. If the determination result is no, resource reselection is performed. With the above solution, resource reselection can be triggered when the beam of the resource does not include the beam associated with the receiving device, which is conducive to improving the success rate of data transmission.

In order to make the above-mentioned purposes, features and beneficial effects of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

Referring to Figure 3, Figure 3 is a schematic diagram of a flow chart of a resource selection method in an embodiment of the present application. The method shown in Figure 3 can be executed by a sending terminal. The method shown in Figure 3 may include:

Step S31: determining whether the beam of the resource includes the beam associated with the receiving device;

Step S32: If the judgment result is no, then perform resource reselection.

In the embodiment of the present application, the Tx UE can be configured to autonomously select resource allocation from a pre-configured resource pool, that is, the Tx UE adopts the above-mentioned mode2 resource allocation method. Resources refer to resources used for communication, and resources can include time domain resources, frequency domain resources and spatial domain resources, and the spatial domain resources are beams.

Furthermore, the beam associated with the receiving device may refer to a beam that enables the receiving device to receive data. In the solution of the embodiment of the present application, the receiving device may refer to a receiving terminal (ie, Rx UE) for data to be transmitted. The number of receiving devices may be one or more.

Before executing step S31, the Tx UE may perform beam training to determine the beam associated with the receiving device. If there are multiple receiving devices, the beams associated with each receiving device may be determined separately. It should be noted that when the Tx UE uses the beam associated with each Rx UE to send data, the Rx UE can receive the data sent by the Tx UE.

As shown in Figure 2, it is assumed that the beam associated with terminal 2 is beam 1. Therefore, when terminal 1 uses beam 1 to send data, terminal 2 can receive the data. Similarly, it is assumed that the beam associated with terminal 3 is beam 2. Therefore, when terminal 1 uses beam 2 to send data, terminal 3 can receive the data.

In the mobile communication scenario, the Tx UE and/or Rx UE are in a state where they may move at any time. In other words, when the relative position between the Tx UE and the Rx UE changes, the beam associated with the Rx UE will also change accordingly. If the Tx UE still uses the original associated beam for data transmission, data transmission failure is likely to occur.

Continuing to refer to FIG. 3 , in the specific implementation of step S31 , a candidate resource set may be obtained first, wherein the candidate resource set may be a resource set reported by the physical layer.

Specifically, when the Tx UE determines that resource selection is required, it can indicate to the physical layer that resources are needed for transmission, and can also indicate to the physical layer the priority of the data to be transmitted, the number of sub-channels occupied by the resources, the number of retransmissions (indicating how many retransmission resources are required in addition to the initial transmission resources), the delay requirements and other information. In response to the received indication, the physical layer can select resources from the resource pool in a perceptual manner and generate a set of candidate resources.

In one embodiment of the present application, after obtaining a candidate resource set from the physical layer and before selecting a resource for transmission from the candidate resource set, it can be determined whether the beam of each resource in the candidate resource set includes the beam associated with the receiving device. Among them, each resource is determined by physical layer perception. During the process of resource perception, the physical layer performs resource perception in different beam directions respectively, and selects idle time-frequency resources in different beam directions. Therefore, the beam of each resource in the candidate resource set has direction-related information, so it can be determined whether the beam of each resource includes the beam associated with the receiving device.

It should be noted that, in the scheme of the embodiment of the present application, beam x includes beam y, which means that the coverage of beam x includes at least a portion of the coverage of beam y. More specifically, beam x including beam y may include one or more of the following situations: the coverage of beam x is the same as the coverage of beam y; the coverage of beam y is within the coverage of beam x; the coverage of beam x and the coverage of beam y partially overlap. In the scheme of this embodiment, beam x is the beam of the resource, and beam y is the beam associated with the receiving device. Therefore, the inclusion of the beam of the resource with the beam associated with the receiving device can be understood as the coverage of the beam of the resource includes at least a portion of the coverage of the beam associated with the receiving device.

Referring to Figure 6, Figure 6 is a schematic diagram of a beam in an embodiment of the present application. As shown in Figure 6, the coverage range of the beam of the resource is the same as the coverage range of the beam associated with the receiving device. That is, the coverage of the beam of the resource completely overlaps with the coverage of the beam associated with the receiving device. In this case, the enhancement effect of logical channel priority processing is the best, which can maximize the success rate of data transmission.

Referring to FIG. 7 , FIG. 7 is a schematic diagram of another beam in an embodiment of the present application. As shown in FIG. 7 , the coverage of the beam associated with the receiving device is within the coverage of the beam of the resource. That is, the coverage of the beam of the resource completely covers the coverage of the beam associated with the receiving device. In this case, the enhancement effect of the logical channel priority processing is better, which can greatly improve the success rate of data transmission.

Referring to Fig. 8, Fig. 8 is a schematic diagram of another beam in an embodiment of the present application. As shown in Fig. 8, the coverage of the beam associated with the receiving device and the coverage of the beam of the resource partially overlap. That is, a portion of the coverage of the beam associated with the receiving device is within the coverage of the beam of the resource.

In a specific implementation, for the beam of each resource in the candidate resource set, it can be determined whether the coverage of the beam includes the coverage of the beam associated with the receiving device.

If the beams of each resource in the candidate resource set do not include the beam associated with the receiving device, the judgment result can be determined to be no. In other words, it can be determined that the triggering condition for resource reselection is met. That is, if the beams of each resource in the candidate resource set do not include the beam associated with the receiving device, resource reselection can be triggered.

If the beam of at least one resource in the candidate resource set includes the beam associated with the receiving device, resource reselection may not be triggered.

In a possible implementation, the receiving device may refer to any receiving device. That is, for each resource beam in the candidate resource set, it may be determined whether the coverage of the beam includes the coverage of the beam associated with any receiving device.

As an example, if the number of Rx UEs is multiple, if the beams of each resource in the candidate resource set do not include at least one beam associated with the Rx UE, resource reselection may be triggered. If the beam of at least one resource includes at least one beam associated with the Rx UE, resource reselection is not triggered.

In another possible implementation, the receiving device may be a specific receiving device. That is, for each resource beam in the candidate resource set, it may be determined whether the coverage of the beam includes the coverage of the beam associated with the specific receiving device. The specific receiving device may be the receiving device that triggers this resource selection.

As another example, if the beams of each resource in the candidate resource set do not include the beam associated with the specific Rx UE, resource reselection may be triggered. If the beam of at least one resource includes the beam associated with the specific Rx UE, resource reselection is not triggered.

Specifically, performing resource reselection may refer to instructing the physical layer to perform resource selection again to trigger the physical layer to re-perform resource perception, thereby generating and reporting a new set of candidate resources.

Before performing resource reselection, beam training may be performed and a transmit beam may be determined, wherein the transmit beam may include a beam associated with an Rx UE. In the case where the number of Rx UEs is multiple, the transmit beam may include a beam associated with at least one Rx UE. In the process of performing resource reselection, an idle resource may be selected from a resource pool according to the determined transmit beam.

The above scheme takes into account the situation where the beam switching is caused by the movement of the terminal during the resource selection process, that is, as the terminal moves, the beam associated with the receiving terminal changes. To this end, in the scheme of this embodiment, before selecting the beam, it can be determined whether the beam in the candidate resource set includes the beam associated with the receiving terminal. When the beam in the candidate resource set does not include the beam associated with the receiving terminal, it can be determined that the beam in the candidate resource set is unavailable, the triggering condition for resource reselection is met, and resource reselection is performed. This can improve the success rate of data transmission in mobile communication scenarios.

In another embodiment of the present application, it can be determined whether the beam of the selected resource includes the beam associated with the receiving device. The selected resource may refer to a resource reserved for transmission from a Tx UE to a certain Rx UE.

As an example, the selected resource may be a resource reserved for the first receiving device. In the implementation of step S31, it can be determined whether the selected resource includes the beam associated with the first receiving device. If the beam of the selected resource does not include the beam associated with the receiving device corresponding to the resource (that is, the first receiving device), it is determined that the execution condition of resource reselection is met, and resource reselection is performed. In other words, in this example, for the beam of the resource reserved for the Rx UE, resource reselection is triggered only when the beam does not include the beam associated with the Rx UE.

As shown in FIG2 , the beam of resources reserved by terminal 1 for terminal 3 is beam 3, and the beam associated with terminal 3 is beam 2. When beam 3 does not include beam 2, resource reselection may be triggered.

As another example, the selected resource may be a resource reserved for the first receiving device. In the specific implementation of step S31, it may be determined whether the selected resource includes a beam associated with any receiving device. If the selected resource includes a beam associated with at least one receiving device, it is determined that the triggering condition for resource reselection is not met, that is, resource reselection is not triggered. If the selected resource does not include a beam associated with any receiving device, it is determined that the triggering condition for resource reselection is met, and resource reselection is triggered.

As shown in FIG2 , the beam of resources reserved by terminal 1 for terminal 3 is beam 3, and beam 3 does not include beam 2 associated with terminal 3. If beam 3 includes beam 1 associated with terminal 2, even if beam 3 does not include beam 2, since beam 3 includes beam 1, resource reselection is not triggered, and terminal 1 can use beam 3 to send data to terminal 2. If beam 3 does not include beam 1 associated with terminal 2, resource reselection can be triggered.

In a specific implementation, for the selected resources, it can be periodically determined whether the beam of the selected resources includes the beam associated with the receiving device, so as to promptly detect the situation where the beam is unavailable, thereby promptly reselecting the resources to ensure effective transmission of data.

The above scheme takes into account the situation that the beam switching occurs due to the movement of the terminal after resource selection. That is, as the terminal moves, the beam associated with the receiving terminal changes, and the beam of the resource reserved for the receiving terminal may become unavailable. To this end, in the scheme of this embodiment, it can be determined whether the selected beam includes the beam associated with the receiving terminal. When the selected beam does not include the reserved beam associated with the receiving terminal, or does not include any A beam associated with a receiving terminal can determine that the selected beam is unavailable, thereby triggering resource reselection, which can improve the success rate of data transmission in mobile communication scenarios.

For more information about triggering resource reselection, please refer to the above description and will not be repeated here.

From the above, the solution of the embodiment of the present application provides a trigger mechanism for resource reselection, which triggers resource reselection when the beam to be selected or the selected beam does not include the beam associated with the receiving device, thereby improving the success rate of data transmission.
