Description

Priority updating method, equipment and system

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to a priority updating method, equipment and a system.

Background

Currently, a Channel Access Priority Class (CAPC) in a wireless communication system includes four channel access priorities. The four channel access priorities may be used when a User Equipment (UE) is transmitting data in a Licensed Assisted Access (LAA) carrier.

In a new radio in unlicensed band (NR-U) scenario based on an unlicensed frequency band, a UE may preempt a channel according to a channel access priority indicated to the UE by a network device before performing data transmission. Specifically, the UE may perform channel sensing according to the channel access priority to determine whether the channel is idle; if the channel is idle, the UE may transmit data on the channel, and if the channel is busy, the UE may not transmit data.

However, since the channel access priority indicated to the UE by the network device is usually the lowest channel access priority in the logical channel or the logical channel group, when the UE uses the lowest channel access priority to preempt the channel, the time for the UE to listen to the channel may be longer, and at this time, if there is bursty high-priority data to be transmitted, the high-priority data may not be transmitted in time due to the too long time for the UE to listen to the channel, so that the performance of the UE to transmit data is poor.

Disclosure of Invention

The embodiment of the invention provides a priority updating method, equipment and a system, which aim to solve the problem that the performance of UE for transmitting data is poor because the UE cannot transmit high-priority data in time due to too long time for monitoring a channel.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The term "and/or" herein is an association relationship describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. The symbol "/" herein denotes a relationship in which the associated object is or, for example, a/B denotes a or B.

The terms "first" and "second," and the like, in the description and in the claims of the present invention are used for distinguishing between different objects and not for describing a particular order of the objects. For example, the first channel access priority and the second channel access priority, etc. are for distinguishing different channel access priorities, rather than for describing a particular order of channel access priorities.

In the embodiments of the present invention, words such as "exemplary" or "for example" are used to mean serving as examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

In the description of the embodiments of the present invention, unless otherwise specified, "a plurality" means two or more, for example, a plurality of elements means two or more elements, and the like.

The embodiment of the invention provides a priority updating method, equipment and a system, wherein UE (user equipment) can update a second channel access priority stored in the UE to a first channel access priority under the condition that the first channel access priority is higher than the second channel access priority, the first channel access priority is a channel access priority corresponding to first data to be sent, and the second channel access priority is a channel access priority indicated to the UE by network equipment. According to the scheme, the higher the channel access priority adopted by the UE to preempt the channel is, the shorter the time for the UE to monitor the channel is, namely the higher the probability that the UE preempts the channel is, so that when the channel access priority corresponding to the data actually required to be transmitted by the UE is greater than the channel access priority indicated by the network equipment to the UE, the channel can be preempted by the UE according to the channel access priority corresponding to the data actually required to be transmitted by the UE, namely the channel can be preempted by the UE according to the higher channel access priority, so that the probability that the channel is preempted by the UE can be improved, the data required to be transmitted by the UE can be transmitted by the UE in time, and the data transmission performance.

The priority updating method provided by the embodiment of the invention can be applied to a communication system. The communication system may be a wireless communication system, which may include a network device and a UE. Fig. 1 is a schematic diagram of a wireless communication system according to an embodiment of the present invention. In fig. 1, a wireless communication system may include a network apparatus 01 and a UE 02. Wherein, the network device 01 and the UE 02 can establish a connection. It is understood that a wireless connection may be between network device 01 and UE 02.

Optionally, in this embodiment of the present invention, the UE is a device providing voice and/or data connectivity to a user, a handheld device having a wired/wireless connection function, or another processing device connected to a wireless modem. A UE may communicate with one or more core network devices via a Radio Access Network (RAN). The UEs may be mobile terminals such as mobile phones (or "cellular" phones) and computers with mobile terminals, as well as portable, pocket, hand-held, computer-included, or vehicle-mounted mobile devices that exchange language and/or data with the RAN, such as Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), and the like. The UE may also be referred to as a user agent (user agent) or UE, etc.

In the embodiment of the present invention, the network device is a device deployed in the RAN for providing a wireless communication function for the UE. In the embodiment of the present invention, 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 using different radio access technologies, the names of devices that function as base stations may differ. For example, in a 5G system, it may be referred to as a 5G base station (gNB); in fourth Generation wireless communication (4-Generation, 4G) systems, such as Long Term Evolution (LTE) systems, may be referred to as evolved base stations (enbs); in a third generation mobile communication (3G) system, it may be referred to as a base station (Node B) or the like. As communication technology evolves, the name "base station" may change.

In the embodiment of the invention, before the UE performs data transmission, the UE can compete with other UEs for the channel, namely the UE can preempt the channel. In the case that the UE preempts the channel, the UE may perform data transmission. Specifically, the UE may contend for the channel with other UEs according to the channel access priority indicated to the UE by the network device. However, since the channel access priority indicated to the UE by the network device may not match the channel access priority corresponding to the data to be actually sent by the UE, for example, the channel access priority indicated to the UE by the network device is lower than the channel access priority corresponding to the data to be actually sent by the UE, when the UE uses the channel access priority indicated to the UE by the network device to preempt the channel, the UE may not preempt the channel or cannot preempt the channel in time. In order to solve the problem, in the embodiment of the present invention, the UE may autonomously determine an appropriate channel access priority according to data to be sent in the UE, so that the probability that the UE occupies a channel may be increased, and the UE may timely transmit data that the UE needs to transmit.

It should be noted that, in the embodiment of the present invention, the channel access priority may be used to instruct the UE to preempt the priority of the channel. The priority of the UE for preempting the channel may be represented by some parameters, for example, the duration of the UE listening to the channel, the duration of the UE occupying the channel, and other parameters. Specifically, the higher the priority of the UE for occupying the channel is, the shorter the duration of channel interception by the UE is; the lower the priority of the UE for occupying the channel is, the longer the time for the UE to listen to the channel is. The higher the priority of the UE for occupying the channel is, the shorter the time length of the UE for occupying the channel is; the lower the priority of the UE for occupying the channel is, the longer the time length of the UE for occupying the channel is.

In the embodiment of the present invention, the channel access priority may also be referred to as a CAPC value. Specifically, in an actual implementation, the CAPC values may include 4 CAPC values, where the 4 CAPC values are: 1. 2, 3 and 4. Wherein, the smaller the CAPC value, the higher the channel access priority.

The priority updating method provided by the embodiment of the invention is exemplarily described below with reference to the drawings.

As shown in fig. 2, an embodiment of the present invention provides a priority updating method, which may be applied to the wireless communication system shown in fig. 1, and which may include S201-S202 described below.

S201, the UE compares the first channel access priority with the second channel access priority.

The first channel access priority may be a channel access priority corresponding to first data to be sent. Specifically, the first channel access priority may be a channel access priority corresponding to a quality of service class identifier (QCI) of the first data.

The second channel access priority may be a channel access priority indicated by the network device to the UE.

It should be noted that, in the embodiment of the present invention, QCIs of different data may be different, and channel access priorities corresponding to different QCIs may also be different. In general, QCIs may include standardized QCIs and non-standardized QCIs (e.g., operator-specific QCIs, etc.). Specifically, each standardized QCI may explicitly correspond to a channel access priority. Since the non-standardized QCI cannot clearly correspond to one channel access priority, the channel access priority corresponding to the non-standardized QCI may be a channel access priority corresponding to a standardized QCI whose target information is closest to the non-standardized QCI.

Wherein, the target information may include at least one of the following: parameters of data corresponding to the non-standardized QCI, attributes of the data corresponding to the non-standardized QCI, and transmission requirements of the data corresponding to the non-standardized QCI. Of course, the target information may also include any other possible information, which may be determined according to actual usage requirements, and the embodiment of the present invention is not limited.

Illustratively, as shown in table 1, a table of correspondence between the normalized QCI and the channel access priority (i.e., the CAPC value) is provided for the embodiment of the present invention.

TABLE 1

CAPC value	QCI
		1	1、3、5、65、66、69、70
2	2、7
		3	4、6、8、9
4	-

It should be noted that, in the embodiment of the present invention, the normalized QCI can be directly determined according to table 1. For non-normalized QCIs, the target information corresponding to the non-normalized QCIs may be combined and determined according to table 1 above.

Optionally, in an embodiment of the present invention, the first data may be second data, third data, or fourth data. The second data may be data to be transmitted, which is pre-sent (or to be understood) by the UE to preempt the channel by using the second channel access priority; the third data may be data satisfying the first condition received by the UE before transmitting the second data; the fourth data may be data that the UE can assemble into the second data and the third data, i.e., the fourth data may be data that the UE can assemble into a data packet each time of the second data and the third data.

Specifically, the third data may be data that satisfies the first condition and is received by the UE before the UE authorizes/authorizes the second data to be sent.

Wherein the first condition may include any one of: the priority is higher than that of the second data, the data of the preset data type and the data needing to be sent on the preset logical channel.

It should be noted that, in the embodiment of the present invention, the data to be sent of the UE that preempts the channel by using the second channel access priority may be understood as follows: the UE should access the priority preemption channel by using the second channel originally, and the preempted channel is used to send the data to be sent.

Optionally, in this embodiment of the present invention, the preset data type may be a data type agreed between an operator providing service for the UE and the UE, or a data type determined by the UE according to a protocol agreement, or a data type configured by the network device for the UE, and may specifically be determined according to an actual use requirement, which is not limited in this embodiment of the present invention.

For example, the predetermined data type may be low-latency high-reliability connectivity (URLLC) type data.

Optionally, in this embodiment of the present invention, the preset logical channel may be a logical channel determined by the UE according to a protocol agreement, or a logical channel configured by the network device to the UE, or a logical channel indicated by the network device to the UE. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

In the embodiment of the present invention, since the second data, the third data, and the fourth data are data in different scenes, the first data may be data in different scenes, and thus the UE may compare the channel access priorities corresponding to the data in different scenes with the second channel access priority, that is, the priority updating method provided in the embodiment of the present invention may be applied to a plurality of scenes, so that the flexibility of using the priority updating method provided in the embodiment of the present invention may be improved.

Optionally, in an embodiment of the present invention, when the first data is the second data, the first data may be data that satisfies a second condition in the second data. Wherein the second condition may include any one of: the corresponding channel has the lowest access priority to the data, the data of the preset data type and the data needing to be sent on the preset logical channel.

Optionally, in this embodiment of the present invention, when the first data is the fourth data, the first data may be data of the fourth data, where a corresponding channel access priority of the data is the lowest.

It should be noted that, when the first data is the second data (that is, the data to be transmitted of the UE that preempts the channel by using the second channel access priority), since the second data may include a plurality of data, that is, the channel access priority corresponding to the second data may include a plurality of channel access priorities, the UE may compare the lowest channel access priority corresponding to the second data with the second channel access priority based on the principle of fair contention for the channel. When the first data is the third data (i.e., the data satisfying the first condition received by the UE before the second data is transmitted), since the channel access priority corresponding to the third data is determined (i.e., the third data corresponds to one channel access priority), the UE may directly compare the channel access priority of the third data with the second channel access priority. When the first data is the fourth data (i.e., data that can be assembled by the UE in the second data and the third data), since the channel access priority corresponding to the fourth data may include multiple channel access priorities, the UE may use the lowest channel access priority corresponding to the fourth data to compare with the second channel access priority based on the principle of fair contention for the channel.

The first data and the first channel priority corresponding to the first data are exemplarily described in different implementations below.

The first implementation mode comprises the following steps: the second data is multiplexing data (i.e., data that can be assembled into a currently transmitted data packet) in data to be transmitted (hereinafter referred to as target data) in which the UE preempts the channel by using the channel access priority (i.e., the second channel access priority) indicated by the network device. In this case, the first data is data with the lowest corresponding channel access priority in the multiplexed data; that is, the first data is the data with the lowest channel access priority in the second data.

It should be noted that, in the embodiment of the present invention, the multiplexing data may be data that can be assembled into a data packet in the second data.

In a first implementation, before the UE sends or assembles the second data, the UE may compare the CAPC value corresponding to the QCI of the first data (i.e., the first channel access priority described above, hereinafter referred to as the first CAPC value) with the CAPC value indicated to the UE by the network device (i.e., the second channel access priority described above, hereinafter referred to as the second CAPC value). If the first CAPC value is less than the second CAPC value, or the first CAPC value is less than the second CAPC value, and an absolute value of a difference between the second CAPC value and the first CAPC value is greater than a first value, the UE may determine that the first channel access priority corresponding to the QCI of the first data is higher than the second channel access priority indicated to the UE by the network device. In this way, the UE may preempt the channel using the first channel access priority corresponding to the QCI of the first data, that is, the UE may preempt the channel using a higher channel access priority, so that the probability that the UE preempts the channel may be increased.

Optionally, in this embodiment of the present invention, the first value may be a value configured by the network device to the UE, or a value indicated by the network device to the UE, or a value determined by the UE according to a protocol agreement. The method can be determined according to actual use requirements, and is not limited in the embodiment of the invention.

For example, the first value may be 1. The method can be determined according to actual use requirements, and is not limited in the embodiment of the invention.

The second implementation mode comprises the following steps: the second data is data to be assembled in the target data (i.e. data to be transmitted of the UE that preempts the channel by using the channel access priority indicated by the network device). In this case, the first data is the data with the lowest corresponding channel access priority in the data to be assembled; that is, the first data is the data with the lowest channel access priority in the second data.

Optionally, for the second implementation manner, the second data may be all data in the target data, or may be partial data in the target data. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

In a second implementation, before the UE sends or assembles the second data, the UE may compare the CAPC value corresponding to the QCI of the first data (i.e., the first channel access priority, hereinafter referred to as the first CAPC value) with the CAPC value indicated by the network device to the UE (i.e., the second channel access priority, hereinafter referred to as the second CAPC value). If the first CAPC value is less than the second CAPC value, or the first CAPC value is less than the second CAPC value, and an absolute value of a difference between the second CAPC value and the first CAPC value is greater than a first value, the UE may determine that the first channel access priority corresponding to the QCI of the first data is higher than the second channel access priority indicated to the UE by the network device. In this way, the UE may preempt the channel using the first channel access priority corresponding to the QCI of the first data, that is, the UE may preempt the channel using a higher channel access priority, so that the probability that the UE preempts the channel may be increased.

In the embodiment of the present invention, for the description related to the first value, reference may be specifically made to the detailed description of the first value in the foregoing embodiment, and details are not described here again to avoid repetition.

The third implementation mode comprises the following steps: the second data is data of a preset data type in the target data (that is, data to be sent in which the UE preempts the channel by using the channel access priority indicated by the network device in advance), or data that needs to be sent on a preset logical channel in the target data. In this case, the first data is the second data.

For the description of the preset data type and the preset logical channel, reference may be specifically made to the related description in the foregoing embodiments, and in order to avoid repetition, details are not described here again.

In a third implementation, before the UE sends or assembles the second data, the CAPC value corresponding to the QCI of the first data (i.e., the first channel access priority described above, hereinafter referred to as the first CAPC value) may be compared with the CAPC value indicated by the network device to the UE (i.e., the second channel access priority described above, hereinafter referred to as the second CAPC value). If the first CAPC value is less than the second CAPC value, or the first CAPC value is less than the second CAPC value, and an absolute value of a difference between the second CAPC value and the first CAPC value is greater than a first value, the UE may determine that the first channel access priority corresponding to the QCI of the first data is higher than the second channel access priority indicated to the UE by the network device. In this way, the UE may preempt the channel using the first channel access priority corresponding to the QCI of the first data, that is, the UE may preempt the channel using a higher channel access priority, so that the probability that the UE preempts the channel may be increased.

The fourth implementation mode comprises the following steps: the third data is data that meets the first condition (priority higher than that of the second data, data of a preset data type/data that needs to be sent on a preset logical channel) and is received by the UE before the UE sends the second data (that is, data to be sent of which the UE uses the second channel to access the priority to preempt the channel). In this case, the first data is the third data.

In a fourth implementation manner, before the UE sends the second data, if the UE receives the third data, that is, if the third data arrives in the UE, the UE may compare the CAPC value corresponding to the QCI of the first data (that is, the first channel access priority (hereinafter, referred to as a first CAPC value)) with the CAPC value (that is, the second channel access priority (hereinafter, referred to as a second CAPC value) indicated to the UE by the network device. If the first CAPC value is less than the second CAPC value, or the first CAPC value is less than the second CAPC value, and an absolute value of a difference between the second CAPC value and the first CAPC value is greater than a first value, the UE may determine that the first channel access priority corresponding to the QCI of the first data is higher than the second channel access priority indicated to the UE by the network device. In this way, the UE may preempt the channel using the first channel access priority corresponding to the QCI of the first data, that is, the UE may preempt the channel using a higher channel access priority, so that the probability that the UE preempts the channel may be increased.

The fifth implementation manner: the third data is data which meets the first condition (priority higher than that of the second data, data of a preset data type/data which needs to be sent on a preset logic channel) and is received by the UE before the UE sends the second data (namely the data to be sent of the second channel which is used by the UE to access the priority preemption channel). Specifically, the third data may be data that satisfies the first condition and is received by the UE before the second data is assembled. In this case, the first data is the third data.

It should be noted that, in the fifth implementation manner, if the UE receives the third data before the UE assembles the second data, that is, if the third data arrives in the UE, since the UE assembles the data earlier than the UE transmits the data in the process of transmitting the data by the UE, the third data may also be understood as the data that satisfies the first condition and is received by the UE before transmitting the second data.

In a fifth implementation, before the UE sends the second data, if the UE receives the third data, that is, the third data arrives in the UE earlier than the UE assembles the second data, the UE may compare the CAPC value corresponding to the QCI of the first data (that is, the third data) (that is, the first channel access priority, which is hereinafter referred to as a first CAPC value) with the CAPC value indicated to the UE by the network device (that is, the second channel access priority, which is hereinafter referred to as a second CAPC value). If the first CAPC value is less than the second CAPC value, or the first CAPC value is less than the second CAPC value, and an absolute value of a difference between the second CAPC value and the first CAPC value is greater than a first value, the UE may determine that the first channel access priority corresponding to the QCI of the first data is higher than the second channel access priority indicated to the UE by the network device. In this way, the UE may preempt the channel using the first channel access priority corresponding to the QCI of the first data, that is, the UE may preempt the channel using a higher channel access priority, so that the probability that the UE preempts the channel may be increased.

The sixth implementation manner: the fourth data is data that can be assembled from the second data (i.e., data to be transmitted for which the UE preempts the channel with the second channel access priority) and the third data (data satisfying the first condition and received by the UE before transmitting the second data). In this case, the first data is data having the lowest channel access priority among the fourth data.

In a sixth implementation, before the UE sends the second data, if the UE receives the third data, that is, the third data arrives in the UE earlier than the second data assembled by the UE, the UE may compare the CAPC value (that is, the first channel access priority, hereinafter referred to as a first CAPC value) corresponding to the QCI of the first data (that is, the data with the lowest channel access priority in the fourth data) with the CAPC value (that is, the second channel access priority, hereinafter referred to as a second CAPC value) indicated to the UE by the network device. If the first CAPC value is less than the second CAPC value, or the first CAPC value is less than the second CAPC value, and an absolute value of a difference between the second CAPC value and the first CAPC value is greater than a first value, the UE may determine that the first channel access priority corresponding to the QCI of the first data is higher than the second channel access priority indicated to the UE by the network device. In this way, the UE may preempt the channel using the first channel access priority corresponding to the QCI of the first data, that is, the UE may preempt the channel using a higher channel access priority, so that the probability that the UE preempts the channel may be increased.

It is to be understood that, for the sixth implementation manner, since the UE compares the assemblable data (i.e., the fourth data) in the second data and the third data, that is, the assemblable data may include the third data, in a case that the first CAPC value is smaller than the second CAPC value, or the first CAPC value is smaller than the second CAPC value, and a difference between the second CAPC value and the first CAPC value is greater than a first value, it may be determined that the arrival of the third data affects the assembly of the second data by the UE.

In the embodiment of the present invention, since the channel access priorities corresponding to different data (e.g., the second data, the third data, and the fourth data) may be different, when the first data is different data, the UE may compare the channel access priorities corresponding to the different data with the second channel access priority, so that flexibility and accuracy of using the channel access priorities by the UE may be improved.

S202, under the condition that the first channel access priority is higher than the second channel access priority, the UE updates the second channel access priority stored in the UE to the first channel access priority.

In the embodiment of the present invention, when the UE determines that the first channel access priority is higher than the second channel access priority, the UE may update the second channel access priority to the first channel access priority, and then the UE may directly use the first channel access priority to preempt the channel, that is, the UE may use the first channel access priority as the channel access priority of the subsequent transmission data. In this way, the UE may preempt the channel with a higher channel access priority.

It can be understood that, in the embodiment of the present invention, if the UE determines that the first channel access priority is equal to or lower than the second channel access priority, the UE may determine that the channel preempted by using the second channel access priority can meet the transmission requirement of the first data, so that the UE may not update the second channel access priority, that is, the UE may continue to preempt the channel by using the second channel access priority. In this way, the UE may preempt the channel using the channel access priority matching the first data.

The embodiment of the invention provides a priority updating method, because the higher the channel access priority adopted by UE when occupying a channel is, the shorter the time for the UE to monitor the channel is, that is, the higher the probability of the UE occupying the channel is, when the channel access priority corresponding to the data actually required to be transmitted by the UE is greater than the channel access priority indicated to the UE by network equipment, the UE can occupy the channel by adopting the channel access priority corresponding to the data actually required to be transmitted by the UE, that is, the UE can occupy the channel by adopting the higher channel access priority, so that the probability of the UE occupying the channel can be improved, the UE can transmit the data required to be transmitted by the UE in time, and the performance of the UE for transmitting the data can be improved.

Optionally, in this embodiment of the present invention, the UE may compare the first channel access priority with the second channel access priority when the UE has a capability of updating the channel access priority stored in the UE, and update the second channel access priority stored in the UE when the first channel access priority is higher than the second channel access priority. The capability of the UE to update the channel access priority stored in the UE may be determined by target indication information, where the target indication information may be used to indicate that the UE may update the channel access priority stored in the UE.

Illustratively, in conjunction with fig. 2, as shown in fig. 3, S201 may be specifically implemented by S201a described below.

S201a, the UE compares the first channel access priority with the second channel access priority according to the target indication information.

In this embodiment of the present invention, when the UE includes the target indication information, the UE may determine, according to the target indication information, that the UE may update the channel access priority stored in the UE, so that the UE may compare the first channel access priority with the second channel access priority, and when the first channel access priority is higher than the second channel access priority, the UE may update the second channel access priority stored in the UE to the first channel access priority. In this way, the UE can preempt the channel by using the first channel access priority, that is, the UE can preempt the channel by using a higher channel access priority, so that the probability that the UE preempts the channel can be increased.

It can be understood that, in the embodiment of the present invention, if the UE does not include the target indication information, that is, the UE does not have the capability of updating the channel access priority stored in the UE, the UE may not compare the first channel access priority with the second channel access priority, so that even if the first channel access priority is higher than the second channel access priority, the UE does not update the second channel access priority stored in the UE.

Optionally, in this embodiment of the present invention, the target indication information may be indicated to the UE by the network device, or configured to the UE by the network device, or predefined (for example, agreed by the network device and the UE or specified in a communication protocol).

For example, when the target indication information is indicated to the UE by the network device, the network device may indicate the target indication information to the UE by carrying the target indication information in a message or signaling. For example, the network device may indicate the target indication information to the UE by carrying the target indication information in Downlink Control Information (DCI).

Of course, in the embodiment of the present invention, the network device may also indicate the target indication information to the UE in any other possible manner, which may be determined specifically according to actual usage requirements, and the embodiment of the present invention is not limited.

For another example, when the target indication information is configured by the network device to the UE, the network device may configure the target indication information to the UE by carrying the target indication information in a message or signaling. For example, the network device may configure the target indication information to the UE in Radio Resource Control (RRC) signaling.

Of course, in the embodiment of the present invention, the network device may also configure the target indication information to the UE in any other possible manner, which may be determined specifically according to actual usage requirements, and the embodiment of the present invention is not limited.

In this embodiment of the present invention, since the target indication information may be used to indicate the UE to update the channel access priority stored in the UE, the UE may update the channel access priority stored in the UE (i.e., update the second channel access priority to the first channel access priority) according to the target indication information when the UE obtains the target indication information and when the first channel access priority is higher than the second channel access priority. Therefore, the UE can determine the required channel access priority according to the actual requirement, so that the channel access priority used by the UE is more appropriate, and the probability of the UE occupying the channel can be improved.

Optionally, in the embodiment of the present invention, after the UE updates the second channel access priority stored in the UE to the first channel access priority, the UE may send an indication message (for example, the first indication message in the embodiment of the present invention) to the network device to notify the network device, and the UE uses the first channel access priority to preempt the channel.

With reference to fig. 2, as shown in fig. 4, after S202, the priority updating method provided in the embodiment of the present invention may further include S203-S204 described below.

S203, the UE sends first indication information to the network equipment.

The first indication information may be used to instruct the UE to preempt the channel using the first channel access priority. That is, after the UE updates the second channel access priority to the first channel access priority, the UE may send first indication information to the network device to notify the network device that the UE uses the first channel access priority to preempt the channel in subsequent data transmission.

Optionally, in this embodiment of the present invention, the UE may send the first indication information to the network device by carrying the first indication information in the first data; or, the UE may also separately send the first indication information to the network device.

Of course, in actual implementation, the UE may also send the first indication information to the network device in any other possible manner, which may be determined according to actual usage requirements, and the embodiment of the present invention is not limited.

S204, the network equipment receives the first indication information.

In this embodiment of the present invention, after the UE updates the second channel access priority to the first channel access priority, the UE may send the first indication information to the network device, that is, the network device may receive the first indication information sent by the UE, so that the network device may determine that the UE uses the first channel access priority to preempt the channel.

Optionally, in the embodiment of the present invention, each time the UE updates the channel access priority stored in the UE, the UE may send the indication information to the network device once, so as to notify the network device that the UE uses the updated channel access priority to preempt the channel, so that the network device may receive a plurality of indication information sent by the UE.

In the embodiment of the present invention, since the first indication information is used to indicate the UE to preempt the channel by using the first channel access priority, the network device may determine, according to the first indication information sent by the UE, that the UE updates the channel access priority indicated by the network device to the UE, so that the network device may monitor which channel access priority (for example, the first channel access priority or the second channel access priority) the UE uses to preempt the channel, and thus the network device may determine, according to a monitoring result, whether the channel access priority indicated by the network device to the UE is appropriate, and may further adjust the channel access priority indicated by the network device to the UE in time.

Optionally, in this embodiment of the present invention, after the network device receives the multiple pieces of indication information, the network device may determine, according to the multiple pieces of indication information, an accuracy (e.g., a target accuracy in this embodiment of the present invention) that the network device indicates the channel access priority to the UE, and in a case that the accuracy is smaller than a certain threshold, the network device may adjust the channel access priority that the network device indicates to the UE.

Illustratively, in conjunction with fig. 4, as shown in fig. 5, after S204, the priority updating method provided by the embodiment of the present invention may further include S205-S206 described below.

S205, after the network equipment receives the plurality of indication information, the network equipment determines the target accuracy according to the plurality of indication information.

The target accuracy may be used to indicate the accuracy of the network device indicating the channel access priority to the UE. Each of the plurality of indication information may be sent after the UE updates the channel access priority stored in the UE.

In the embodiment of the present invention, after the network device receives the multiple pieces of indication information sent by the UE, the network device may determine, according to the multiple pieces of indication information, the accuracy (i.e., the target accuracy) that the network device indicates the channel access priority to the UE.

Optionally, the multiple pieces of indication information may be all pieces of indication information sent by the UE, multiple pieces of indication information sent by the UE within a certain time period, or multiple pieces of indication information sent by the UE within a specific time period. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

It is to be understood that, in the embodiment of the present invention, the plurality of pieces of indication information may include the first indication information, or may not include the first indication information. Specifically, the determination may be determined according to actual use requirements, and the embodiment of the present invention is not limited.

In this embodiment of the present invention, the target accuracy may be a ratio of the number of the plurality of pieces of indication information to the number of times that the network device indicates the channel access priority to the UE.

Specifically, in the embodiment of the present invention, when the plurality of pieces of indication information are all pieces of indication information sent by the UE, the target accuracy may be a ratio of the plurality of pieces of indication information to a total number of times that the network device indicates the channel access priority to the UE. When the plurality of pieces of indication information are indication information sent by the UE within a certain time period, the target accuracy may be a ratio of the plurality of pieces of indication information to the number of times that the network device indicates the channel access priority to the UE within the certain time period. When the plurality of pieces of indication information are indication information sent by the UE in a specific time period, the target accuracy may be a ratio of the plurality of pieces of indication information to the number of times that the network device indicates the channel access priority to the UE in the specific time period.

S206, under the condition that the target accuracy is smaller than the preset threshold, the network equipment adjusts the channel access priority indicated by the network equipment to the UE.

In the embodiment of the present invention, after the network device determines the target accuracy, the network device may compare the target accuracy with the preset threshold, and when the target accuracy is smaller than the preset threshold, the network device may determine that the accuracy of indicating the channel access priority to the UE by the network device is low, so that the network device may adjust the channel access priority indicated by the network device to the UE, thereby reducing the probability of updating the channel access priority stored in the UE by the UE to a certain extent, and thus saving resources of the UE.

Optionally, in this embodiment of the present invention, the preset threshold may be a numerical value preset in the network device by an operator to which the network device belongs. The preset value may be an optimized value determined by an operator to which the network device belongs according to a large amount of sample data. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

Illustratively, the preset threshold may be 0.4 or 0.5.

In the embodiment of the present invention, the preset value is exemplified by 0.4 or 0.5, and the preset value is not limited to the embodiment of the present invention. In actual implementation, the preset value may also be any other possible value, which may be determined according to actual use requirements, and the embodiment of the present invention is not limited.

In the embodiment of the present invention, the network device may compare the target accuracy with the preset threshold, and when the target accuracy is smaller than the preset threshold, the network device may determine that the accuracy of the channel access priority indicated to the UE by the network device is low, so that the network device may adjust the channel access priority indicated to the UE by the network device, thereby reducing the probability that the UE updates the channel access priority stored in the UE to a certain extent, and further saving resources of the UE.
