Technical Field
The present application relates to the field of wireless communications technologies, and in particular, to a method and a device for sending a Scheduling Request (SR).
Background
When the terminal needs to transmit data, the terminal sends an SR to the network side device to request uplink resources. When SR is initially triggered, SR _ COUNTER (SR count) is set to 0, SR _ COUNTER is accumulated to 1 every time SR is successfully transmitted, and when SR _ COUNTER is accumulated to a maximum value SR _ transmitMax, the UE triggers a random access procedure, that is, acquires an UL (Uplink) grant through the random access procedure, so as to perform data transmission on UL resources.
Unlicensed Spectrum transmission SR used in NR-U (New Radio in Unlicensed Spectrum) networks. In the unlicensed spectrum, in order to reduce interference caused by users using the unlicensed spectrum, channel detection is required, and SR is transmitted when a channel is idle, and SR transmission is stopped when the channel is occupied. If the channel of the unlicensed spectrum cannot be waited for to be idle all the time, the terminal does not send the SR, so there is no way to accumulate SR _ COUNTER, which results in that SR _ transmitMax cannot be accumulated, UL grant cannot be obtained through the random access process, and finally, the terminal cannot obtain UL resources, and data transmission delay increases.

Detailed Description
Hereinafter, some terms in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.
(1) In the embodiments of the present application, the terms "network" and "system" are often used interchangeably, but those skilled in the art can understand the meaning.
(2) In the embodiments of the present application, the term "plurality" means two or more, and other terms are similar thereto.
(3) "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
When the terminal performs data transmission, the terminal needs to send uplink data to be transmitted to the network side device, so that the network side device determines whether to allocate uplink resources to the terminal. Therefore, NR (New radio, next generation radio) is a mechanism of Scheduling Request (SR).
A terminal sends Uplink transmission resources needed to be used for UL-SCH (Uplink-Shared Channel) transmission to network side equipment through an SR; the network side device detects whether a terminal sends an SR on the allocated SR resources, and after receiving the SR, the network side device allocates uplink resources to the terminal, where the allocated uplink resources are at least sufficient for the terminal to send BSR (Buffer Status Report) resources.
Currently, there are two forms of SR transmission, which are dedicated SR transmission and random access SR transmission, respectively;
the dedicated SR transmission is to transmit an SR using a PUCCH (Physical Uplink Control channel) dedicated resource configured by the network side device.
The random access SR transmission is to acquire uplink resources through a random access procedure.
At present, considering that different services have different delay requirements, a 5G system allows a network side device to configure multiple sets of dedicated SR resources for a terminal, selects SR resources therein according to different services, and may also configure a mapping relationship between each logical channel and the dedicated SR resources. When discovering that the conventional BSR is triggered, the terminal firstly determines a logic channel for triggering the conventional BSR; and if determining that no UL resource aiming at the conventional BSR exists, the terminal selects available special SR resources according to the mapping relation between the logic channel and the special SR resources, and transmits the SR by utilizing the special SR resources. If the logical channel triggering the regular BSR is not configured with dedicated SR resources, the terminal will be triggered to initiate a random access SR. In addition, when the terminal uses the dedicated SR resource to reach the maximum transmission number, the random access SR is also triggered.
If the dedicated SR Resource cannot transmit the SR, the terminal further needs to perform processes such as notifying a Radio Resource Control (RRC) layer to release Physical Uplink Control Channel (PUCCH) resources corresponding to all serving cells, notifying the RRC layer to release Sounding Radio Signal (SRs) resources corresponding to all serving cells, and clearing up Uplink/downlink semi-persistent scheduling resources.
A MAC (Medium Access control) entity may be configured with 0, 1 or more SR configurations. One SR configuration includes a plurality of BWPs (Bandwidth parts) and PUCCH resources on a cell. For one logical channel, only one PUCCH resource can be configured on each BWP at most.
Each SR configuration corresponds to 1 or more logical channels, each logical channel may correspond to 0 or 1 SR, where the logical channel corresponding to the SR configuration and the SR corresponding to the logical channel are configured by RRC signaling.
Among them, the SR capable of triggering the BSR is a pending SR.
Since the UE does not have a PUSCH (Physical Uplink shared Channel) resource to transmit the BSR, the UE transmits the SR request UL resource on the PUCCH. The network side device may allocate one dedicated SR resource for transmitting the SR to each UE. The dedicated SR resources are periodic, occurring once every n slots or symbols.
As shown in fig. 1, an example of SR transmission is: after data arrives, the UE triggers an SR, sends an SR on the next closest SR resource, receives an UL grant, and sends data on a PUSCH (UL-SCH) indicated by the UL grant, where the sent data generally refers to a data packet containing a BSR.
When SR is initially triggered, a parameter SR _ COUNTER is set to be 0, and when SR is successfully sent once, SR _ COUNTER is accumulated to be 1, if SR _ COUNTER is accumulated to be the maximum value SR _ TransmitMax, UE triggers a random access process, namely, UL authorization is obtained through the random access process.
In NR-U networks, unlicensed spectrum transmission SR is used. In the unlicensed spectrum, in order to reduce interference caused by users using the unlicensed spectrum, channel detection is required, and SR is transmitted when a channel is idle, and SR transmission is stopped when the channel is occupied. If the channel of the unlicensed spectrum cannot be waited for to be idle all the time, the terminal does not send the SR, so there is no way to accumulate SR _ COUNTER, which results in that SR _ transmitMax cannot be accumulated, UL grant cannot be obtained through the random access process, and finally, the terminal cannot obtain UL resources, and data transmission delay increases.
Based on the above, the present application provides a method and an apparatus for transmitting an SR, to solve the problem that if a channel that cannot wait for an unlicensed spectrum is idle when an SR is transmitted using a licensed spectrum, a terminal cannot accumulate SR _ COUNTER because the terminal does not actually transmit the SR, and thus cannot reach the maximum value of SR _ COUNTER. Therefore, the terminal cannot acquire the UL grant through the random access process, and the terminal cannot acquire the UL resource, which results in an increase in data transmission delay. In the present application: the terminal judges whether the update condition for sending the SR is met, updates the SR configuration information after the update condition for sending the SR is determined to be met, sends the SR by using the updated SR configuration information so as to improve the success rate of sending the SR, further obtains UL authorization through a random access process, and transmits data through the obtained UL resources so as to reduce data transmission delay.
In the embodiment of the application, the terminal is a device with a wireless communication function, and can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on the water surface (such as a ship and the like); and may also be deployed in the air (e.g., airplanes, balloons, satellites, etc.). The terminal can be a Mobile Phone (Mobile Phone), a tablet computer (Pad), a computer with wireless transceiving function, a Virtual Reality (VR) terminal, an Augmented Reality (AR) terminal, a wireless terminal in Industrial Control (Industrial Control), a wireless terminal in unmanned Driving (Self Driving), a wireless terminal in Remote Medical treatment (Remote Medical), a wireless terminal in Smart Grid (Smart Grid), a wireless terminal in Transportation Safety (Transportation Safety), a wireless terminal in Smart City (Smart City), a wireless terminal in Smart Home (Smart Home), etc.; but also various forms of terminals, Mobile Stations (MS), and Terminal devices (Terminal devices).
The network side device may be a base station, and is a device for providing a wireless communication function for a terminal, including but not limited to: a gbb in 5G, a Radio Network Controller (RNC), a Node B (Node B, NB), a Base Station Controller (BSC), a Base Transceiver Station (BTS), a Home Base Station (e.g., Home Evolved NodeB or Home Node B, HNB), a BaseBand Unit (Base band Unit, BBU), a transmission Point (transmission and reception Point, TRP), a Transmission Point (TP), a mobile switching center, and the like. The base station in the present application may also be a device that provides a terminal with a wireless communication function in other communication systems that may appear in the future.
In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be described in further detail with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. 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.
As shown in fig. 2, a flowchart of a method for sending an SR according to an embodiment of the present application includes the following steps:
in step 200, the terminal judges whether the updating condition of the scheduling request SR is met.
In the application, after the terminal determines that data arrives on the logical channel and triggers the BSR, but determines that there is no UL grant corresponding to the logical channel and the BSR cannot be transmitted through the uplink resource, the terminal triggers the SR to acquire the uplink resource for data transmission.
And after the terminal triggers the SR, the terminal sends the SR on the unauthorized frequency spectrum resource. When the SR is transmitted on the unlicensed spectrum resource, the unlicensed spectrum resource may collide with other resources, or the terminal detects that the SR transmission channel is in a non-idle state, that is, the SR transmission channel is busy, at this time, the terminal cannot transmit the SR on the unlicensed spectrum resource, and if the SR cannot be transmitted for a long time, the terminal cannot acquire the UL grant, so that the BSR cannot be transmitted through the UL resource, and the transmission delay is increased.
In order to send the SR as soon as possible, the SR configuration information may be updated, such as switching an unlicensed spectrum resource to a licensed spectrum resource, sending the SR on the licensed spectrum resource, or raising the SR sending priority, so that the SR is sent preferentially when a collision occurs. However, before updating the SR configuration information, the terminal must determine whether the update condition for transmitting the SR is satisfied, and the terminal may update the SR configuration information only when the update condition for transmitting the SR is satisfied.
And step 210, if the update condition for sending the SR is determined to be satisfied, the terminal updates the SR configuration information and sends the SR using the updated SR configuration information.
In the application, after determining that the update condition for transmitting the SR is satisfied, the terminal updates the SR configuration information and transmits the SR by using the updated SR configuration information; the success rate of transmitting the SR is improved, the uplink resources distributed by the network side equipment according to the SR are obtained, data transmission is carried out on the uplink resources, and data transmission delay is reduced.
In the present application, the terminal determines whether the SR update condition is satisfied by:
the first method is as follows: and after the terminal determines that one or a plurality of continuous SR sending resources can not send the SR, determining that the updating condition of the SR is met.
In this case, a counter is set for counting the number of SR transmission resources that cannot transmit the SR continuously, and the number of one or more SR transmission resources that cannot transmit the SR continuously is configured or predefined by the network side device; and when one or a plurality of continuous SR transmission resources are determined not to be capable of transmitting the SR, determining that the update condition of the SR is met.
For example, the number of SR transmission resources that cannot transmit an SR is preset to be 3, and when 3 consecutive SR transmission resources cannot transmit an SR, it is determined that the SR update condition is satisfied. If the first SR transmission resource cannot transmit the SR, but the second SR transmission resource successfully transmits the SR, the counter counts again.
The second method comprises the following steps: and after the terminal determines that the SR sending resource can not send the SR within the set time length, the terminal determines that the updating condition for sending the SR is met.
In this case, a timer is set for timing the SR transmission, and when it is determined that the SR cannot be transmitted within the set time period, it is determined that the update condition for transmitting the SR is satisfied. The set duration of the timer is configured or predefined by the network side device.
In the present application, when updating SR configuration information: updating SR sending resources in the SR configuration information; and/or
And updating the SR sending priority in the SR configuration information.
The SR transmission resource in the SR configuration information is updated to switch the unlicensed spectrum resource to the licensed spectrum resource, and the licensed spectrum resource is configured by the network side device.
Updating the SR sending priority in the SR configuration information, wherein the priority comprises: the priority of the SR configuration and/or the priority of the logical channel corresponding to the SR, and the priority is configured by the network side equipment.
In the present application, the SR configuration information is updated only when the update condition is satisfied, and the SR is transmitted using the updated SR configuration information, but there are a variety of determination conditions for determining whether the update condition of the SR is satisfied, and there are two ways of updating the SR configuration information after the update condition of the SR is satisfied.
The details are described in detail by the following examples.
The first embodiment is as follows: and updating the SR sending resource in the SR configuration information.
In the application, the terminal updates the SR configuration information after determining that the update condition for sending the SR is met.
The terminal judges whether the update condition of the transmission SR is met or not by the following modes:
if one or a plurality of continuous SR sending resources are determined to be incapable of sending the SR, determining that the updating condition for sending the SR is met; and/or
And if the SR sending resource cannot send the SR within the set time length, determining that the updating condition for sending the SR is met.
There are thus two cases:
the first condition is as follows: and when one or a plurality of continuous SR sending resources are determined to be incapable of sending the SR, updating the SR sending resources in the SR configuration information.
In this embodiment, when the terminal determines that data arrives on a logical channel and triggers a BSR, and determines that there is no UL grant corresponding to the triggered BSR and BSR transmission is not possible, the terminal transmits an SR through an unlicensed spectrum resource and starts a counter;
the SR sending through the unauthorized spectrum resource is parameter information configured in advance by the network side equipment; the threshold value of the counter is the number of SR transmission resources that cannot transmit the SR, and the number of SR transmission resources that cannot transmit the SR may be parameter information configured by the network side device, or may be predefined.
Further, the terminal judges whether the current SR sending resource can send the SR, and after the current SR sending resource cannot send the SR, the count value of the counter is added with 1 in an accumulated manner or is subtracted with 1 on the basis of the threshold value;
the terminal determines whether the current SR transmission resource can not transmit the SR in the following way:
if the SR sending resource conflicts with other resources, determining that the SR sending resource cannot send the SR; and/or
And if the SR transmission channel is found to be busy through the LBT, determining that the SR transmission resource can not transmit the SR.
Therefore, when the above situation occurs, if the counter counts in an accumulation manner, 1 is added on the basis of the value of the current counter, and after the accumulated value is determined to reach the threshold value, the update condition for transmitting the SR is determined to be satisfied, and the transmission resource in the SR configuration information is updated;
if the counter adopts a decreasing mode, 1 is subtracted on the basis of the value of the current counter. And after the threshold value is reduced to 0, the terminal determines that the updating condition for transmitting the SR is met, and updates the transmission resource in the SR configuration information.
Wherein, the SR transmission resource in the SR configuration information is updated as follows: switching the unlicensed spectrum resources to licensed spectrum resources;
after switching to the licensed spectrum resources, the SR is transmitted on the licensed spectrum resources.
Correspondingly, the network side equipment receives the SR sent by the terminal on the corresponding unauthorized spectrum resource and authorized spectrum resource;
when receiving the SR sent by the terminal, the network side device first receives the SR sent by the terminal on the unlicensed spectrum resource, and if the SR is not received at the location of the unlicensed spectrum resource, receives the SR at the location of the licensed spectrum resource.
And after receiving the SR sent by the terminal, sending an UL grant to the terminal, so that the terminal sends a BSR on UL resources.
Fig. 3 is a schematic diagram of a first transmission SR provided in the embodiment of the present application. As can be seen from fig. 3, when the terminal cannot transmit the SR for 3 consecutive times while transmitting the SR on the unlicensed spectrum resource, the terminal transmits the SR on the licensed spectrum resource.
Case two: and when the SR sending resource cannot send the SR within the set time length is determined, updating the SR sending resource in the SR configuration information.
In this embodiment, when the terminal determines that data arrives on the logical channel and triggers the BSR, and determines that there is no UL grant corresponding to the triggered BSR and BSR transmission is not possible, the terminal transmits an SR through an unlicensed spectrum resource and starts a timer;
the SR sending through the unauthorized spectrum resource is parameter information configured in advance by the network side equipment; the set duration of the timer may be parameter information configured in advance by the network side device, or may be predefined.
Further, the terminal judges whether the current SR sending resource can send the SR or not, and updates the sending resource in the SR configuration information after determining that the current SR sending resource cannot send the SR and determining that the timer still cannot send the SR after reaching the set duration.
The terminal determines whether the current SR transmission resource can not transmit the SR in the following way:
if the SR sending resource conflicts with other resources, determining that the SR sending resource cannot send the SR; and/or
And if the SR transmission channel is found to be busy through the LBT, determining that the SR transmission resource can not transmit the SR.
In the application, when a terminal triggers to send an SR on an unlicensed spectrum resource, a timer is started to start timing, and at this time, the initial time of the timer may be 0 or a set duration; when the initial time of the timer is 0, adopting a positive timing mode, and when the timer still cannot send the SR after the set time length is reached, determining that the updating condition of the SR is met, and updating the sending resource in the SR configuration information; or when the initial time of the timer is the set duration, adopting a countdown mode, and when the timer reaches 0 and the SR cannot be sent, determining that the update condition of the SR is met, and updating the sending resource in the SR configuration information.
Wherein, updating the transmission resource in the SR configuration information is: switching the unlicensed spectrum resources to licensed spectrum resources;
after switching to the licensed spectrum resources, the SR is transmitted on the licensed spectrum resources.
Correspondingly, the network side equipment receives the SR sent by the terminal on the corresponding unauthorized spectrum resource and authorized spectrum resource;
when receiving the SR sent by the terminal, the network side device first receives the SR sent by the terminal on the unlicensed spectrum resource, and if the SR is not received at the location of the unlicensed spectrum resource, receives the SR at the location of the licensed spectrum resource.
And after receiving the SR sent by the terminal, sending an UL grant to the terminal, so that the terminal sends a BSR on UL resources.
As shown in fig. 4, which is a schematic diagram of a second SR sending method provided in the embodiment of the present application, it can be known from fig. 4 that after the SR sending time duration on the unlicensed spectrum resource by the terminal reaches the set time duration, the SR cannot be sent, and then the SR is sent on the licensed spectrum resource.
Example two: and updating the SR sending priority in the SR configuration information.
In the application, the terminal updates the SR configuration information after determining that the update condition for sending the SR is met.
The terminal judges whether the update condition of the transmission SR is met or not by the following modes:
if one or a plurality of continuous SR sending resources are determined to be incapable of sending the SR, determining that the updating condition for sending the SR is met; and/or
And if the SR sending resource cannot send the SR within the set time length, determining that the updating condition for sending the SR is met.
There are thus two cases:
and in the third case, when one or a plurality of continuous SR transmission resources are determined to be incapable of transmitting the SR, the SR transmission priority in the SR configuration information is updated.
In this embodiment, when the terminal determines that data arrives on a logical channel and triggers a BSR, and determines that there is no UL grant corresponding to the triggered BSR and BSR transmission is not possible, the terminal transmits an SR through an unlicensed spectrum resource and starts a counter;
the SR sending through the unauthorized spectrum resource is parameter information configured in advance by the network side equipment; the threshold value of the counter is the number of SR transmission resources that cannot transmit the SR, and the number of SR transmission resources that cannot transmit the SR may be parameter information configured in advance by the network side device, or may be predefined.
Further, the terminal judges whether the current SR sending resource can send the SR, and after the current SR sending resource cannot send the SR, the count value of the counter is added with 1 in an accumulated manner or is subtracted with 1 on the basis of the threshold value;
the terminal determines whether the current SR transmission resource can not transmit the SR in the following way:
if the SR sending resource conflicts with other resources, determining that the SR sending resource cannot send the SR; and/or
And if the SR transmission channel is found to be busy through the LBT, determining that the SR transmission resource can not transmit the SR.
Therefore, when the above situation occurs, if the counter counts in an accumulation manner, 1 is added on the basis of the value of the current counter, and after the accumulated value is determined to reach the threshold value, the update condition for transmitting the SR is determined to be met, and the SR transmission priority in the SR configuration information is updated;
if the counter adopts a decreasing mode, 1 is subtracted on the basis of the value of the current counter. And after the threshold value is reduced to 0, the terminal determines that the updating condition for transmitting the SR is met, and updates the transmission resource in the SR configuration information.
The SR sending priority in the SR configuration information is updated as follows: raising the transmission priority of the SR, wherein the priority comprises: a priority of the SR configuration and/or a priority of a logical channel corresponding to the SR.
Wherein, the priority configured by the SR and/or the priority of the logical channel corresponding to the SR is parameter information configured by the network side device; initially, the network side equipment configures a plurality of priority information such as first priority information, second priority information and the like; the second priority information may be first priority information, the first priority information and the second priority may be priorities configured by the SR and/or priorities of logical channels corresponding to the SR, and the second priority information may also be a threshold value.
After the SR sending priority is raised, the updated priority information is used for sending the SR on the unauthorized frequency spectrum resources; such as from a first priority to a second priority, the SR is transmitted over the unlicensed spectrum using the second priority.
When the resource is collided after the priority is updated, the terminal sends the SR preferentially. The resource collision may be a collision with a PUSCH resource, such as configuring a licensed spectrum resource, or dynamically scheduling a resource.
Correspondingly, the network side equipment receives the SR sent by the terminal on the corresponding unauthorized spectrum resource;
and after receiving the SR sent by the terminal, sending an UL grant to the terminal, so that the terminal sends a BSR on UL resources.
As shown in fig. 5, which is a schematic diagram of a third SR transmission provided in the embodiment of the present application, as can be seen from fig. 4, when a terminal cannot transmit an SR for 3 consecutive times on an unlicensed spectrum resource, priority of SR configuration is raised, and an SR is transmitted on a next SR resource on the unlicensed spectrum resource by using the raised priority.
And fourthly, when the SR sending resource cannot send the SR within the set time length is determined, updating the SR sending priority in the SR configuration information.
In this embodiment, when the terminal determines that data arrives on the logical channel and triggers the BSR, and determines that there is no UL grant corresponding to the triggered BSR and BSR transmission is not possible, the terminal transmits an SR through an unlicensed spectrum resource and starts a timer;
the SR sending through the unauthorized spectrum resource is parameter information configured in advance by the network side equipment; the set duration of the timer may be parameter information configured in advance by the network side device, or may be predefined.
Further, the terminal judges whether the current SR sending resource can send the SR or not, and updates the sending resource in the SR configuration information after determining that the current SR sending resource cannot send the SR and determining that the timer still cannot send the SR after reaching the set duration.
The terminal determines whether the current SR transmission resource can not transmit the SR in the following way:
if the SR sending resource conflicts with other resources, determining that the SR sending resource cannot send the SR; and/or
And if the SR transmission channel is found to be busy through the LBT, determining that the SR transmission resource can not transmit the SR.
In the application, when a terminal triggers to send an SR on an unlicensed spectrum resource, a timer is started to start timing, and at this time, the initial time of the timer may be 0 or a set duration; when the initial time of the timer is 0, adopting a positive timing mode, and when the timer still cannot send the SR after the set time length is reached, determining that the updating condition of the SR is met, and updating the sending resource in the SR configuration information; or when the initial time of the timer is the set duration, adopting a countdown mode, and when the timer reaches 0 and the SR cannot be sent, determining that the update condition of the SR is met, and updating the sending resource in the SR configuration information.
The SR sending priority in the SR configuration information is updated as follows: raising the transmission priority of the SR, wherein the priority comprises: a priority of the SR configuration and/or a priority of a logical channel corresponding to the SR.
Wherein, the priority configured by the SR and/or the priority of the logical channel corresponding to the SR is parameter information configured by the network side device; initially, the network side equipment configures a plurality of priority information such as first priority information, second priority information and the like; the second priority information may be first priority information, the first priority information and the second priority may be priorities configured by the SR and/or priorities of logical channels corresponding to the SR, and the second priority information may also be a threshold value.
After the sending priority of the SR is improved, the SR is sent by using the updated priority information on the unauthorized frequency spectrum resources; such as from a first priority to a second priority, the SR is transmitted over the unlicensed spectrum using the second priority.
When the resource is collided after the priority is updated, the terminal sends the SR preferentially. The resource collision may be a collision with a PUSCH resource, such as configuring a licensed spectrum resource, or dynamically scheduling a resource.
Correspondingly, the network side equipment receives the SR sent by the terminal on the corresponding unauthorized spectrum resource;
and after receiving the SR sent by the terminal, sending an UL grant to the terminal, so that the terminal sends a BSR on UL resources.
As shown in fig. 6, which is a schematic diagram of a fourth SR sending method provided in the embodiment of the present application, as can be seen from fig. 6, when the terminal still cannot send the SR within the set duration on the unlicensed spectrum resource, the priority of the SR configuration is raised, and the SR is sent on the next SR resource on the unlicensed spectrum resource by using the raised priority.
It should be noted that any combination of the above-mentioned cases may be performed, for example, after one or a plurality of consecutive SR transmission resources cannot transmit an SR within a set time duration, the SR transmission priority is updated, and the SR transmission resources in the SR configuration information are updated, so as to transmit an SR through the updated SR transmission resources, where the SR transmission priority is updated, and other manners are similar and are not described herein again.
As shown in fig. 7, a flowchart of a method for sending an SR according to an embodiment of the present application includes the following steps:
step 700, the network side device determines configuration parameters;
the configuration parameters include SR configuration information corresponding to the logical channel, and the SR configuration information includes part or all of the following: the method comprises the steps of obtaining unauthorized spectrum resources, authorized spectrum resources, first priority information, second priority information and logic channel information triggered to be sent in SR configuration resources;
the first priority information is priority information of the SR or priority information of a logical channel corresponding to the SR, and the second priority information is higher than the first priority information.
In this application, the second priority information may be a threshold value.
Step 710, the network side device sends the configuration parameter to the terminal, so that after the terminal determines that the update condition for sending the SR is satisfied, the SR configuration information is updated according to the configuration parameter, and the SR is sent by using the updated SR configuration information.
In a possible implementation manner, the network side device further configures a threshold value of a counter for the terminal, that is, the number of SR transmission resources that cannot transmit the SR; and configuring the set duration of the timer for the terminal.
