Description

Auxiliary UE selection method, auxiliary UE selection device, communication equipment and storage medium

Technical Field

The present disclosure relates to, but not limited to, the field of communications technologies, and in particular, to a method, an apparatus, a communication device, and a storage medium for selecting an auxiliary UE.

Background

In the related art, in order to support direct communication between a User Equipment (UE) and a UE, a direct link (SL) communication method is introduced; the interface between the UE and the UE is PC-5. According to the corresponding relation between the sending UE and the receiving UE, three transmission modes, namely unicast, multicast and broadcast, are supported on SL.

When the UE autonomously selects transmission resources on the SL, if the neighboring UE selects the same transmission resources, transmission collision may be caused, and reliability is reduced. To avoid such collisions, a sensing (sensing) mechanism is introduced. The UE needs to monitor the direct link control information (Sidelink Control Information, SCI) sent by other UEs continuously or for a period of time to obtain the resource selection information of other UEs; and when the UE performs resource selection, the same transmission resource is prevented from being selected. If part of the resources are not perceived, then the part of the resources that are not perceived cannot be selected when the resources are selected. Meanwhile, according to the channel congestion measurement result, the transmitting UE selects different transmitting resources to avoid the channel from being excessively congested. Some SL transmitting UEs may not have channel sensing and measurement functions, and other UEs are required to provide resource selection auxiliary information for the UE, and the UE performs resource selection according to the received resource selection auxiliary information.

As shown in fig. 2, an embodiment of the present disclosure provides a method for selecting an auxiliary UE, which is applied to a first UE, and includes:

step S21: transmitting first information of a first UE; wherein the first information is used for the second UE to determine whether the first UE can be used as an auxiliary UE for providing the resource selection auxiliary information.

In some embodiments, the first UE and the second UE may each be various types of mobile terminals or fixed terminals. For example, the first UE and the second UE may each be, but are not limited to, a cell phone, a computer, a server, a wearable device, a game control platform, a multimedia device, or the like.

In some embodiments, the first UE and the second UE establish a communication scheme for SL.

In some embodiments, the first UE transmits first information of the first UE to the second UE through SL.

In some embodiments, the first information includes, but is not limited to, at least one of:

movement status information;

spatial location information.

In the embodiment of the disclosure, the first UE may send the movement status information and/or the spatial location information to the second UE, so that the second UE may know whether the first UE is around itself or soon around itself, so that the second UE can accurately determine whether the first UE can be used as an auxiliary UE for selecting and sending the resource selection auxiliary information.

In some embodiments, the movement status information includes:

and the mobile indication information is used for indicating whether the first UE is a mobile UE or not.

The movement indication information herein may include: first movement indication information and second movement indication information. For example, the first movement indication information is "1" for indicating that the first UE is a mobile UE; the second movement indication information is "0" for indicating that the first UE is not a mobile UE or a stationary UE.

As such, in the embodiments of the present disclosure, the first UE sends the movement indication information to the second UE, so that the second UE can know whether the first UE is moving or not, to determine whether the first UE will be close to itself soon.

In some embodiments, the movement status information includes:

and the mobile parameter information is used for indicating the mobile parameters of the mobile UE.

In some embodiments, the movement parameters include, but are not limited to, one of the following:

a first mobility rate parameter for indicating that a mobility rate of the mobile UE is higher than or equal to a predetermined rate;

and a second mobility rate parameter for indicating that the mobility rate of the mobile UE is lower than or equal to a predetermined rate.

In the embodiment of the present disclosure, when the movement rate of the mobile UE (i.e., the first UE) is indicated to be higher than or equal to the predetermined rate, it may be determined that the mobility of the first UE is relatively high, so that the second UE may know whether the first UE approaches itself in a relatively short time; when the movement rate of the mobile UE is indicated to be lower than or equal to the predetermined rate, it may be determined that the mobility of the second UE is relatively low, so that the second UE may know whether the first UE will approach itself for a relatively long time. In this way, the second UE may be enabled to determine, through the mobility parameter, whether the first UE will be very close to itself.

Of course, in other embodiments, the movement rate parameter may also be a movement rate parameter that includes more classifications; for example, the movement rate parameters include: a 1 st movement rate parameter, a 2 nd movement rate parameter, … …, an nth movement rate parameter; the 1 st mobile rate parameter is used for indicating that the mobile rate of the mobile UE is within a 1 st rate threshold range; a 2 nd mobility rate parameter for indicating that a mobility rate of the mobile UE is within a 2 nd rate threshold range; and so on; an nth mobility rate parameter for indicating that a mobility rate of the mobile UE is within an nth rate threshold range; the lower limit of the 1 st rate threshold range is greater than or equal to the upper limit of the 2 nd rate threshold range, the lower limit of the 2 nd rate threshold range is greater than or equal to the upper limit of the 3 rd rate threshold range, … …, and the lower limit of the N-1 th rate threshold range is greater than or equal to the upper limit of the N-th rate threshold range. Where N is a positive integer greater than 2.

In some embodiments, the movement condition parameters include:

and a movement direction parameter for indicating a movement direction of the mobile UE.

In some embodiments, the movement direction parameters include, but are not limited to, one of the following:

a first movement direction parameter for indicating a direction in which the mobile UE moves away from the second UE;

And a second movement direction parameter for indicating a direction in which the mobile UE moves close to the second UE.

In this way, in the embodiment of the present disclosure, the movement direction parameter may also be sent to the second UE by the first UE, so that the second UE can know whether the first UE moves in a direction approaching itself, so that the second UE knows whether the first UE approaches itself soon.

In some embodiments, the spatial location information includes, but is not limited to, at least one of:

the area identifier is used for indicating the identifier of the area where the first UE is located;

and relative location information indicating location information of the first UE with respect to the second UE.

The relative position information may be used to indicate the distance between the first UE and the second UE, or may be used to indicate spatial position information of the first UE and the second UE.

In some embodiments, the location information of the area where each UE is located may be pre-established. Thus, the distance between the first UE and the second UE can be determined according to the area where the first UE is located and the area where the second UE is located.

In the embodiment of the disclosure, the first UE may identify the area of the first UE, so that the second UE knows the area where the first UE is located, thereby determining whether the first UE is around the second UE; the relative position information may also be transmitted by the first UE to the second UE so that the second UE can know whether the first UE is around the second UE. In this way, the embodiment of the disclosure can enable the second UE to accurately determine whether the first UE is around itself.

In some embodiments, the resource selection assistance message includes, but is not limited to, at least one of:

channel congestion rate;

a resource sensing result for indicating resources used by the UEs other than the first UE for transmitting data;

channel measurement results.

In some embodiments, the channel congestion rate is used to indicate the occupancy of the channel.

In some embodiments, the channel measurement is used to indicate a measurement of the channel measurement parameter. For example, the channel measurement is used to indicate a measurement of at least one of channel quality, a received order of a reference signal, and a signal-to-noise ratio.

In the embodiment of the disclosure, the first information of the first UE may be sent by the first UE, and the first information may be used by the second UE to determine whether the first UE can be used as an auxiliary UE for providing the resource selection auxiliary information. In this way, in the embodiment of the present disclosure, it may be accurately determined whether the first UE can be used as an auxiliary UE for providing the resource selection auxiliary information, so that the second UE may obtain relatively accurate resource selection auxiliary information, thereby being beneficial to reducing situations such as resource collision and/or channel congestion as much as possible when the second UE performs resource selection based on the received resource selection auxiliary information.

Moreover, in the embodiment of the present disclosure, the spatial location information may be sent to the second UE by the first UE, so that the second UE can know whether the first UE is around itself; and/or transmitting, by the first UE, the movement status information to the second UE so that the second UE can know whether the first UE is about itself soon. In this way, the embodiment of the disclosure can enable the second UE to select the first UE relatively close to the second UE as the auxiliary UE for transmitting the resource selection auxiliary information, so that the accuracy of the acquired resource selection auxiliary information can be further improved, and the probability of occurrence of resource collision and/or channel congestion can be further reduced.

It should be noted that, as those skilled in the art may understand, the methods provided in the embodiments of the present disclosure may be performed alone or together with some methods in the embodiments of the present disclosure or some methods in the related art.

As shown in fig. 3, an embodiment of the present disclosure provides a method for selecting an auxiliary UE, which is applied to a first UE, and includes:

step S31: receiving a trigger request message;

step S32: and sending the first information of the first UE based on the trigger request message.

In some embodiments, the first UE receives a trigger message sent by the second UE.

The trigger request message here may be sent based on a unicast message or a broadcast message. For example, the first UE establishes a unicast connection with the second UE, and the first UE receives a unicast message carrying a trigger message sent by the second UE. For another example, at least one first UE establishes a multicast connection with a second UE, where the first UE receives a broadcast message carrying a trigger message sent by the second UE.

In some embodiments of the present disclosure, the first information may be the first information described in step S21, which is not described herein.

In the embodiment of the disclosure, the first information of the first UE may be sent by the first UE when the trigger request message is received. In this way, the embodiment of the disclosure transmits the first information only when the trigger request message is received, and compared with the case that the first information of the first UE is always transmitted, network resources can be saved greatly.

As shown in fig. 4, an embodiment of the present disclosure provides a method for selecting an auxiliary UE, which is applied to a first UE, and includes:

Step S41: first information of the first UE is periodically transmitted.

For example, the first UE may transmit the first information at 1 st, 2 nd, … … and nth seconds; wherein N is a positive integer greater than 1.

The method for selecting the auxiliary UE provided by the embodiment of the disclosure comprises the following steps:

determining a period for transmitting first information of a first UE;

the first information of the first UE is periodically transmitted based on the period.

In some embodiments, the first UE receives a period of the second UE transmission. For example, the first UE receives configuration information sent by the second UE, where the configuration information carries a period.

In other embodiments, the first UE pre-configures the period. For example, the first UE configures a period of reporting the first information in advance, or the first UE acquires a period of reporting the first information configured in advance in the communication protocol.

In other embodiments, the above-described period may be determined in any feasible manner, and embodiments of the present disclosure are not limited in this regard.

In the embodiment of the present disclosure, the first UE may periodically report the first information of the first UE. In this way, compared with the method for always sending the first information of the first UE, the embodiment of the disclosure can save network resources on one hand; on the other hand, the method can be suitable for more application scenes, and flexible configuration of the reporting trigger message is realized.

Of course, in other embodiments, the first UE may also send the first information of the first UE aperiodically. Therefore, the method can be applicable to more application scenes and realize more flexible configuration.

As shown in fig. 5, an embodiment of the present disclosure provides a method for selecting an auxiliary UE, which is applied to a first UE, and includes:

step S51: based on the trigger event, first information of the first UE is transmitted.

a trigger event is determined that triggers the first UE to send the first information.

For example, the first UE receives a trigger event sent by the second UE.

For another example, the first UE pre-configures the trigger event.

For another example, the first UE obtains a trigger event configured by the base station.

In other embodiments, a method for selecting an auxiliary UE may also include: and acquiring a trigger event triggering the first UE to send the first information.

Thus, in the embodiments of the present disclosure, the first UE may determine the trigger event in a plurality of manners, for example, may determine the trigger event based on the first UE pre-configuration, may obtain the trigger event configured by the base station, and may also receive the trigger event configured by the second UE for the first UE. The embodiment of the invention can be suitable for accurate selection of auxiliary UE of more application scenes.

In some embodiments, the triggering event includes, but is not limited to, at least one of:

the area where the first UE is located is changed;

the distance of the first UE position change within the predetermined time range is greater than or equal to the predetermined distance;

the distance between the first UE and the second UE is greater than or equal to a predetermined distance.

For example, the first UE has an area 1 at a first time and an area 2 at a second time. In this scenario, the area where the first UE is located changes, so that the first UE may be triggered to send the first message.

As another example, the first UE moves a distance exceeding 50 meters within 1 second. In this scenario, the first UE location changes, which may trigger the first UE to send the first message.

For another example, at the current moment, the distance between the first UE and the second UE is greater than 50 meters. In this scenario, the distance between the first UE and the second UE exceeds a predetermined distance, the first UE being relatively far from the second UE; this may also trigger the first UE to send the first message.

Thus, in the embodiment of the present disclosure, when the first UE leaves the current area, or the position of the first UE changes by more than a certain threshold, or the distance between the first UE and the second UE exceeds a certain threshold, the first UE may be used as a trigger event for causing the first UE to report the first information.

In the embodiment of the disclosure, the first UE may be sent based on the trigger event when the trigger event is acquired by the first UE. Therefore, the second UE can timely know whether the current position of the first UE is around the second UE or is close to the second UE soon, and accordingly whether the first UE can serve as an auxiliary UE for providing resource selection auxiliary information can be timely determined by the second UE, and resource collision and/or channel congestion and other conditions are reduced.

In addition, in the embodiment of the present disclosure, the trigger event may be acquired in multiple manners and/or may be in multiple forms, so that more application scenarios may be applicable, and flexible configuration for assisting UE selection is implemented.

As shown in fig. 6, an embodiment of the present disclosure provides a method for selecting an auxiliary UE, which is applied to a first UE, and includes:

step S61: transmitting first information carrying identification information in response to the first UE being capable of acting as an auxiliary UE for providing resource selection auxiliary information for providing the second UE; the identification information is used for indicating that the first UE can provide resource selection auxiliary information for the second UE.

For example, the identification information is "1" for indicating that the first UE is able to provide the second UE with the selection assistance information.

In the embodiment of the disclosure, the first UE may send the first information when it is determined that the first UE is capable of providing the resource selection auxiliary information for the second UE; and the first message carries identification information indicating the first UE to provide resource selection auxiliary information for the second UE. In this way, the second UE can be made aware that the first UE can provide the resource selection assistance information for the second UE, so that the probability that the second UE determines that the first UE can serve as an assistance UE for providing the resource selection assistance information can be increased.

In addition, in the embodiment of the disclosure, the identification information is carried in the first information transmission, and no additional independent transmission of the identification information is needed, so that network resources can be saved.

As shown in fig. 7, a method for selecting an auxiliary UE according to an embodiment of the present disclosure is applied to a first UE, and includes:

step S71: receiving an acknowledgement message returned based on the first information, wherein the acknowledgement message is used for indicating that the first UE is determined to be an auxiliary UE for transmitting resource selection service information; or receiving a rejection message returned based on the first information, wherein the rejection message is used for indicating that the first UE is determined not to be an auxiliary UE for sending the resource selection service message.

In some embodiments, the acknowledgement message or the rejection message may be sent over the SL.

The acknowledgement message or rejection message here may be sent in signaling carried.

For example, the first UE and the second UE establish a unicast radio resource control (Radio Resource Control, RRC) connection, and the first UE receives RRC signaling carrying an acknowledgement message sent by the second UE. Of course, in other embodiments, the first UE may also receive signaling carrying an acknowledgement message or a rejection message, e.g., may medium access control layer (Media Access Control, MAC) signaling. Of course, in other embodiments, the first UE may also receive the system information broadcast by the second UE, where the system information carries an acknowledgement message or a rejection message.

The acknowledgement message or rejection message here may be carried in the information indication field of the signalling. The acknowledgement message or rejection message here may be indicated by a predetermined number of bits. For example, the acknowledgement message may be "1", the rejection message may be "0"; as another example, the acknowledgement message may be "10" and the rejection message may be "00".

In the embodiment of the disclosure, the first UE may determine that the second UE agrees to provide the resource selection auxiliary information for the first UE by receiving the acknowledgement message sent by the second UE based on the first information; alternatively, the first UE may determine that the second UE does not agree to provide the selection assistance information thereto by the first UE by receiving a rejection message from the second UE based on the first information. As such, in the embodiments of the present disclosure, the first UE may know whether the first UE can provide the auxiliary UE of the resource selection auxiliary information as the second UE by receiving different information returned based on the first information.

It should be noted here that: the following method of secondary UE selection is applied to the second UE, similar to the description of the method of secondary UE selection applied to the first UE. For technical details not disclosed in the selection method embodiment of the auxiliary UE applied to the first UE in the present disclosure, please refer to the description of the selection method embodiment of the auxiliary UE applied to the second UE in the present disclosure, and detailed description thereof is omitted herein.

As shown in fig. 8, an embodiment of the present disclosure provides a method for selecting an auxiliary UE, which is applied to a second UE, including:

In some embodiments, the movement condition parameters include:

In some embodiments, the spatial location information includes at least one of:

In some embodiments, the resource selection assistance message comprises at least one of:

In the embodiment of the disclosure, the second UE may receive the first information of the first UE, so as to accurately determine, based on the first information, whether the first UE can be used as an auxiliary UE for the second UE to provide the resource selection auxiliary information; and the second UE is facilitated to obtain accurate auxiliary information for selecting the resources, so that the second UE can select idle resources as much as possible for data transmission, and the occurrence of resource collision and/or channel congestion and the like can be reduced.

In addition, in the embodiment of the present disclosure, the first information may be spatial location information and/or movement status information, so that the second UE may be enabled to know whether the first UE is around itself or may be around itself soon, and thus the second UE may be enabled to select the first UE closer to itself as the auxiliary UE of the resource selection auxiliary information. In this way, the embodiment of the disclosure may improve the accuracy of the obtained auxiliary information of resource selection, thereby further reducing the probability of resource collision and/or absorption to congestion.

As shown in fig. 9, an embodiment of the present disclosure provides a method for selecting an auxiliary UE, which is applied to a second UE, including:

step S91: based on the first information, it is determined whether the first UE is capable of functioning as an auxiliary UE for providing resource selection auxiliary information.

In some embodiments, the second UE determines, based on the first information, that the first UE is capable of acting as an assisting UE for providing the resource selection assistance information.

In other embodiments, the second UE determines, based on the identification information carried in the first information, that the first UE is capable of acting as an assisting UE for providing the resource selection assisting information.

For example, a method for selecting an auxiliary UE provided in an embodiment of the present disclosure is applied to a second UE, and includes:

and receiving first information carrying identification information, wherein the identification information is used for indicating that the first UE can provide resource selection auxiliary information for a second UE.
