Description

Communication processing method and related device
Technical Field
The present invention relates to the field of communications, and in particular, to a communication processing method and a related apparatus.
Background
Scheduling Request (SR) is a mechanism applied to apply for uplink resources in 5G or Long Term Evolution (LTE). Generally, if the terminal-side device does not have uplink data to be transmitted, the network-side device will not allocate uplink resources to the terminal-side device, so as to avoid waste of the uplink resources. When the terminal side device has uplink data that needs to be transmitted, the terminal side device may send a scheduling request to the network side device, so that the network side device allocates uplink resources needed for transmitting the uplink data to the terminal side device.
In the prior art, when a terminal side device fails to request uplink resources from a network side device through a scheduling request SR, the terminal side device may send a random access preamble (random access preamble) to the network side device; alternatively, when the terminal side device needs to request other data from the network side device, for example, data related to beam failure recovery (beam failure recovery) or System Information (SI), the terminal side device may also send a random access preamble to the network side device. Generally, after a terminal side device transmits a random access preamble to a network side device, the terminal side device cancels a scheduling request SR transmitted to the network side device after transmitting the random access preamble. At this time, after the network side device receives the random access preamble sent by the terminal side device, the network side device sends a Random Access Response (RAR) to the terminal side device. If the random access response RAR does not include the uplink resource, the terminal-side device will send a scheduling request SR to the network-side device again to request the network-side device to allocate the uplink resource to the terminal-side device.
In the above scheme, when the network side device receives the scheduling request SR sent by the terminal side device, the network side device already knows that the terminal side device needs uplink resources, and the network side device receives the random access preamble sent by the terminal side device. Therefore, the network-side device may allocate uplink resources to the terminal-side device in the random access response RAR, or allocate uplink resources to the terminal-side device within a certain time after the random access response RAR. In such a case, the terminal side device does not know that it may obtain the uplink resource, and at this time, if the terminal side device sends the scheduling request SR to the network side device again to request the network side device to allocate the uplink resource to the terminal side device, it will cause that the network side device is repeatedly requested to allocate the uplink resource to the terminal side device, thereby causing waste of the scheduling request SR resource and interference generated between the scheduling request SR resources.
Disclosure of Invention
The embodiment of the application provides a communication processing method and a related device, which are used for saving Scheduling Request (SR) resources and reducing interference generated among the SR resources.
In a first aspect, an embodiment of the present application provides a communication processing method, including: when the terminal-side device needs to send uplink data, if the terminal-side device does not have uplink resources sufficient for sending the uplink data, the terminal-side device may send a first scheduling request SR and a random access preamble to the network-side device to notify the network-side device that the terminal-side device needs the uplink resources to send the uplink data, and then the terminal-side device may receive a response message corresponding to the random access preamble from the network-side device, and then, when the response message does not indicate the uplink resources, the terminal-side device stops retransmission of the first SR within a first duration, where the first duration is a sum of a SR transmission prohibition duration corresponding to the first SR and a first preset duration.
In the embodiment of the application, after the terminal side device sends the first scheduling request SR to the network side device, the network side device can know that the terminal side device needs uplink resources. If the response message received by the terminal side device and replied by the network side device does not indicate uplink resources, the terminal side device stops the retransmission of the first SR within the first duration. Therefore, the terminal side equipment is prevented from repeatedly requesting the network side equipment to allocate the uplink resource to the terminal side equipment within the first time length. Therefore, the scheme can save SR resources, and can reduce interference generated between the SR resources in the first duration as the transmission of the SR is stopped in the first duration.
According to the first aspect, in a first implementation manner of the first aspect of the embodiments of the present application, the random access preamble includes a random access preamble for beam failure recovery or a random access preamble requesting system information.
In this embodiment, a type of a random access preamble is proposed, where the random access preamble may be a random access preamble used for beam failure recovery or a random access preamble requesting system information.
According to the first aspect or the first implementation manner of the first aspect, in a second implementation manner of the first aspect of the embodiments of the present application, the response message is a random access response, and the random access response indicates the first preset duration.
In this embodiment, the response message received by the terminal side device and replied by the network side device is a random access response, and the first duration is indicated by the random access response. Thus, the content and the role of the response message are further clarified.
According to the second implementation manner of the first aspect, in a third implementation manner of the first aspect of this embodiment of the present application, the random access response indicates that the first preset duration is at least one time of an SR configuration period.
In this embodiment, a manner of measuring the first preset duration by using the SR configuration period is provided, and the first preset duration is determined by determining a multiple of the SR configuration period. And since the first duration is the sum of the SR transmission prohibition duration corresponding to the first SR and the first preset duration, the first duration can be adjusted by adjusting the multiple of the SR configuration cycle.
According to the first aspect or the first implementation manner of the first aspect, in a fourth implementation manner of the first aspect of this embodiment of the present application, the response message includes a random access response and a medium access control-control element, MAC CE, where the MAC CE indicates the first preset time duration.
In this embodiment, the response message received by the terminal side device and replied by the network side device includes a random access response and a MAC CE, where the first duration is indicated by the MAC CE. Thus, the content and the role of the response message are further clarified. Compared with the scheme of indicating the first duration by the random access response, which is proposed in the foregoing, the implementation flexibility of the scheme of the embodiment of the present application is increased.
According to a fourth implementation manner of the first aspect, in a fifth implementation manner of the first aspect of this embodiment of the present application, the MAC CE indicates that the first preset duration is at least one time of an SR configuration period.
In this embodiment, a manner of measuring the first preset duration by using the SR configuration period is provided, the first preset duration is determined by determining a multiple of the SR configuration period, and since the first duration is a sum of the SR transmission prohibition duration corresponding to the first SR and the first preset duration, the first duration can be adjusted by adjusting the multiple of the SR configuration period.
In a sixth implementation form of the first aspect as such or according to the first implementation form of the first aspect of the embodiments of the present application, the method further comprises: and when the response message returned by the network side equipment to the terminal side equipment does not indicate the uplink resource, the terminal side equipment sends a second SR to the network side equipment, wherein the priority of the second SR is higher than that of the first SR.
In this embodiment, since the priority of the second SR transmitted by the terminal side device to the network side device is higher than the priority of the first SR, the network side device will process the second SR preferentially when processing various scheduling requests SR. Therefore, the time for the terminal side device to request the network side device for the uplink resource can be shortened.
According to the first aspect, in a seventh implementation manner of the first aspect of the embodiments of the present application, the method further includes: after the terminal side equipment sends the random access preamble to the network side equipment, the timing of SR sending prohibition duration is stopped, and a sending counter of the first SR is initialized; after the terminal side equipment receives the response message sent by the network side equipment, the terminal side equipment starts the timing of the SR sending prohibition duration; and under the condition that the first time length is overtime and the terminal side equipment is not indicated by the network side equipment to the uplink resource, the terminal side equipment retransmits the first SR to the network side equipment.
In this embodiment, after the terminal side device sends the random access preamble to the network side device, the terminal side device stops timing of SR transmission prohibition duration, and initializes the transmission counter of the first SR; and after the terminal side equipment receives the response message sent by the network side equipment, starting the timing of the SR sending prohibition duration. Therefore, the time for the terminal side device to retransmit the first SR can be prolonged, and in addition, the transmission counter of the first SR is initialized, and the scheduling request SR can be prevented from reaching the maximum transmission times to trigger the ordinary random access procedure.
According to the first aspect, in an eighth implementation manner of the first aspect of this embodiment of the present application, the method further includes: before the terminal side device sends the first SR to the network side device, the terminal side device triggers the first SR, wherein the triggered first SR is in a suspended state; after the terminal side device sends the random access request to the network side device, the terminal side device maintains the suspension state of the first SR; after the terminal side device receives the response message sent by the network side device, if the terminal side device is not indicated by the network side device for the uplink resource, the terminal side device resends the first SR in the suspended state to the network side device.
In this embodiment, after the terminal-side device sends the random access request to the network-side device, the terminal-side device will maintain the suspended state of the first SR, that is, the terminal-side device will not cancel suspending the first SR. Thus, when the terminal-side device has a need to transmit the first SR, the terminal-side device may directly transmit the first SR in the suspended state without additionally triggering a scheduling request SR. Therefore, the waste of the SR resources can be reduced, and the interference generated between the SR resources in the first time period can be reduced because the transmission of the SR in the first time period is reduced.
According to the third implementation manner of the first aspect or the fifth implementation manner of the first aspect, in a ninth implementation manner of the first aspect of the embodiment of the present application, the SR configuration cycle is an SR transmission prohibition duration.
In this embodiment, a relationship between the SR configuration period and the existing SR transmission prohibition duration is proposed, and the first SR configuration period may be equal to the SR transmission prohibition duration, but in the later protocol, the SR configuration period may also be equal to the duration of another determined timer, and is not limited herein. The embodiment increases the implementation flexibility of the scheme.
In a tenth implementation manner of the first aspect of the present application, according to any one of the second implementation manner of the first aspect to the fifth implementation manner of the first aspect, the method further includes: and when the first duration is reached and the terminal side device is not indicated by the network side device for the uplink resource, the terminal device retransmits the first SR.
In this embodiment, after receiving the indication of the response message, the terminal side device will not send the first SR until the time that the terminal side device waits has reached the first duration. If the network-side device does not indicate uplink resources to the terminal-side device at this time, the terminal-side device will resend the first SR to request the network-side device to allocate uplink resources to the terminal-side device.
According to a sixth implementation manner of the first aspect, in an eleventh implementation manner of the first aspect of this embodiment of the present application, the sending, by the terminal-side device, the second SR to the network-side device includes: and the terminal side equipment sends the second SR to the network side equipment after the second time length.

In this embodiment, a scheme is proposed in which the indication information in the random access response is used to indicate the terminal-side device to stop sending the first SR to the network-side device within the first duration, and compared with a scheme in which the random access response directly indicates the terminal-side device to stop sending the first SR to the network-side device within the first duration, implementation flexibility of the scheme is increased.
According to a fourth implementation manner of the first aspect, in a thirteenth implementation manner of the first aspect of the embodiment of the present application, the MAC CE includes indication information, where the indication information is used to instruct the terminal-side device to stop sending the first SR to the network-side device within a first duration.
In this embodiment, a scheme is proposed in which indication information in a control-control element MAC CE is used to indicate the terminal-side device to stop sending the first SR to the network-side device within the first duration, which increases implementation flexibility of the scheme compared with a scheme in which the control-control element MAC CE directly indicates the terminal-side device to stop sending the first SR to the network-side device within the first duration.
According to the second implementation manner of the first aspect, in a fourteenth implementation manner of the first aspect of this embodiment of the present application, the random access response indicates that the first preset time duration is a waiting timer.
In this embodiment, it is proposed that the first preset time duration is modified by modifying the time duration of the self-defined timer, where the waiting timer in this embodiment refers to a self-defined timer capable of modifying time duration, and in practical applications, the self-defined timer capable of modifying time duration may be referred to by other names. Thus, the implementation flexibility of the scheme is increased.

In this embodiment, after receiving the random access preamble sent by the terminal side device, the network side device sends a response message corresponding to the random access preamble to the terminal side device, where the response message is used to instruct the terminal side device to stop resending the first SR within a first duration when the indication message does not indicate uplink resources. Therefore, the terminal side equipment is prevented from repeatedly requesting the network side equipment to allocate the uplink resource to the terminal side equipment within the first time length. Therefore, the scheme can save SR resources, and because the transmission of the SR within the first duration is reduced, the interference generated between the SR resources within the first duration can be reduced.

In this embodiment, a manner of measuring the first preset duration by using the SR configuration period is provided, and the first preset duration is determined by determining a multiple of the SR configuration period. And since the first duration is the sum of the SR transmission prohibition duration corresponding to the first SR and the first preset duration, the first duration can be adjusted by adjusting the multiple of the SR configuration cycle.

In this embodiment, a manner of measuring the first preset duration by using the SR configuration period is provided, and the first preset duration is determined by determining a multiple of the SR configuration period. And since the first duration is the sum of the SR transmission prohibition duration corresponding to the first SR and the first preset duration, the first duration can be adjusted by adjusting the multiple of the SR configuration cycle.

In this embodiment, after receiving the second SR sent by the terminal device, the network side has a higher priority than the first SR. Therefore, the network side device will preferentially process the second SR and send the uplink resource to the terminal side device according to the second SR, thereby shortening the time for the terminal side device to request the uplink resource from the network side device.
According to the third implementation manner of the second aspect or the fifth implementation manner of the second aspect, in a seventh implementation manner of the second aspect of the embodiment of the present application, the SR configuration cycle is an SR transmission prohibition duration.

scheduling Request (SR): the method refers to a mode that terminal side equipment applies uplink resources to network side equipment to transmit data.
Random access procedure (random access procedure): the process from the terminal side equipment sending random access preamble to the process before the terminal side equipment and the network side equipment establish signaling connection is started. In this process, the terminal side device sends a random access preamble to the network side device, and the response of the network side device to the random access preamble of the terminal side device is a random access response RAR.
Trigger (trigger): in this embodiment of the present application, an action of the terminal side device before sending the scheduling request SR is referred to, and after the terminal side device triggers a scheduling request SR, the scheduling request SR is in a "pending" state, which may be understood as that the terminal side device prepares but has not sent the scheduling request SR to the network side device. Generally, the terminal side device needs to trigger the scheduling request SR first, and then send the scheduling request SR.
Suspend (suspend): in the embodiment of the present application, when a terminal-side device is in a state where a scheduling request is after the scheduling request is triggered, the terminal-side device does not need to trigger another scheduling request when the scheduling request is in a suspended state, but can directly send the scheduling request in the suspended state to a network-side device.
SR transmission prohibit duration (SR-probibittimer): the SR prohibit timer is also called SR prohibit timer, and is used to monitor a scheduling request SR transmitted in a Physical Uplink Control Channel (PUCCH), when the SR prohibit timer is running, the terminal side device cannot transmit the scheduling request SR, and when the SR prohibit timer is overtime, the terminal side device retransmits the scheduling request SR until a maximum number of times of transmission of the scheduling request (dsr-TransMax) is reached.
SR configuration period: refers to a time period configured by the network side device. The network side device may indicate the number of the time period to the terminal side device. In this embodiment of the present application, the duration of the SR configuration period may be equal to the SR transmission prohibition duration, or may be equal to the duration of another timer, and is not limited herein.
Medium access control-control element (MAC CE): the MAC control unit occupies a fixed bit size, distinguishes the type of the MAC CE through different Logical Channel Identifiers (LCIDs) in a header of a protocol data packet, and carries control information of the MAC layer, such as a Buffer Status Report (BSR), Discontinuous Reception (DRX), and Power Headroom Report (PHR).
Uplink Grant (UL Grant): the network side device grants a right of the terminal side device to enable the terminal side device to send uplink data to the network side device, and after the network side device sends an uplink grant to the terminal side device, the network side device can also allocate uplink resources to the terminal side device in the uplink grant.
The following introduces application scenarios to which the embodiments of the present application are adapted:
the method provided by the embodiment of the application is mainly applied to a scene that the terminal side equipment requests the network side equipment for uplink resources.
In the existing LTE or 5G network architecture, if a terminal side device needs to send uplink data to a network side device, the terminal side device needs to have a certain qualification for using uplink resources, which is also called uplink grant. If the terminal side device does not have available uplink resources, the terminal side device may apply for the uplink resources by sending a scheduling request SR to the network side device. After the network side device receives the scheduling request SR sent by the terminal side device, the network side device may know that the terminal side device needs uplink resources to transmit uplink data, and thus the network side device should allocate certain uplink resources to the terminal side device. However, after the network side device receives the scheduling request SR sent by the terminal side device, because the network quality is not good, the network side device does not successfully allocate the uplink resource to the terminal side device, or the network side device is too busy and has not yet come to allocate the uplink resource to the terminal side device, or the network side device fails to allocate the uplink resource to the terminal side device in time due to other situations, which is not limited herein. Then, the terminal side device will not obtain the uplink resource. However, the terminal side device has a requirement for transmitting uplink data, and then the terminal side device initiates a random access RA to the network side device to apply for uplink resources from the network side device.
In addition to the above-described scenarios, there is also such a scenario. When the terminal side equipment needs to send uplink data, the terminal side equipment sends a scheduling request SR to the network side equipment to apply for uplink resources, but when the terminal side equipment does not obtain the uplink resources, the terminal side equipment initiates a random access preamble related to beam failure recovery, and the purpose of the random access preamble related to beam failure recovery is to request the network side equipment for beam failure recovery, and uplink resources cannot be obtained necessarily. At this time, the occurrence of the random access preamble for beam failure recovery will cause the scheduling request SR to be cancelled.
In addition to the above-described scenario, there is also a scenario similar to beam failure recovery. When the terminal side equipment sends a scheduling request SR to the network side equipment to apply for the uplink resource and the terminal side equipment has not obtained the uplink resource, the terminal side equipment initiates a random access preamble requesting system information SI, and the purpose of the random access preamble requesting system information SI is to request the network side equipment for the system information SI, but not necessarily obtain the uplink resource. At this time, the occurrence of the random access preamble requesting the system information SI will also cause the scheduling request SR to be cancelled.
The terminal side device in the embodiment of the present application may be an independent terminal, and may also be a chip for implementing the terminal function, which is not limited herein. The terminal-side device can be manufactured, sold or used as a stand-alone product, whether as a terminal or as a chip. In this embodiment and the following embodiments, only the terminal-side device is taken as an example for description.
The network side device in this embodiment of the present application may be an independent base station, or may be a chip for implementing the function of the base station, and is not limited herein. The network side device can be manufactured, sold or used as an independent product whether as a base station or as a chip. In this embodiment and the following embodiments, only the network side device is taken as an example for description.
It should be noted that the random access RA in this embodiment may be a contention-based random access RA, or may also be a non-contention-based random access RA, which is not limited herein.
In this embodiment, the uplink data includes control signaling and service data, where the service data includes an ultra-reliable low latency communication (URLLC) service, an enhanced mobile broadband (eMBB) service, a mass machine type communication (mtc) service, and the like, and is not limited herein.
In order to better understand the scheme proposed in the embodiment of the present application, a specific flow of the communication processing method in the embodiment is described below, as shown in fig. 1, which is the communication processing method provided in the embodiment, and the terminal side device and the network side device in the method perform the following steps, including the following contents.
101. The terminal side equipment triggers the first SR, wherein the triggered first SR is in a suspended state.
In this embodiment, when the terminal side device needs to send uplink data to the network side device, the terminal side device may apply for an uplink resource to the network side device in a manner of a scheduling request SR. At this time, the terminal side device may trigger the first scheduling request SR, and after the terminal side device triggers the first SR, the first SR is in a suspended state, where the suspended state means that the terminal side device may directly send the first SR in the suspended state to the network side device without triggering another scheduling request. Specifically, referring to fig. 2A, when the terminal-side device triggers the first SR at time T1, the region from time T1 to time T2 represents that the first SR is in a suspended state, wherein time T2 indicates that the terminal-side device cancels suspending the first SR. Regarding time T2, details will be described later, and detailed description thereof is omitted.
102. The terminal side equipment sends a first SR to the network side equipment.
In this embodiment, after the terminal side device triggers the first SR, the terminal side device may send the first SR to a network side device, where the first SR is used to request an uplink resource from the network side device. After the network side device receives the first SR, the network side device may know that the terminal side device needs to send uplink data.
In this embodiment, after the terminal side device triggers the first SR, the first SR may be aligned with the time domain of the PUCCH immediately, or a certain time gap may exist to be aligned with the time domain of the PUCCH, which is not limited herein. Therefore, in fig. 2A, the time (time T1) when the terminal side device triggers the first SR may overlap with the time when the terminal side device transmits the first SR to the network side device, or a certain time gap may be reserved, which is not limited herein.
103. The terminal side equipment sends a random access preamble to the network side equipment.
In this embodiment, when the terminal side device does not successfully acquire the uplink resource through the first SR. For example, due to poor network quality, the network side device does not successfully allocate the uplink resource to the terminal side device, or, due to network delay, the network side device has not yet reached allocation of the uplink resource to the terminal side device, or, due to some other reason, the network side device has not yet reached allocation of the uplink resource to the terminal side device, which is not limited herein. At this time, the terminal side device may send a random access preamble to the network side device, where the random access preamble may be a random access preamble for requesting uplink resources from the network side device.
It should be noted that the random access preamble may also be a random access preamble for beam failure recovery. Before the beam failure recovery, the terminal side device may have triggered and sent the first SR one or more times, but because the beam quality is poor, the terminal side device does not receive the uplink grant of the network side device, and at this time, the terminal side device detects the beam failure, and the terminal side device sends a random access preamble for beam failure recovery to the network side device.
The beam failure recovery refers to a beam failure recovery process, which includes two parts, namely beam failure detection and beam failure recovery. Generally, a terminal side device measures a downlink beam, and if the beam quality of the downlink beam is lower than a measurement threshold, the terminal side device triggers a beam failure recovery process, so that the terminal side device can switch to a new beam to perform operations such as data transceiving.
Besides, the random access preamble may also be a random access preamble requesting system information SI. At this time, the terminal side device needs to apply for the uplink resource and send a scheduling request SR to the network side device, and then the terminal side device needs to request system information SI from the network side device. Then, the terminal side device transmits a random access preamble requesting system information SI to the network side device.
It should be noted that the transmission of the various random access preambles described above will cause the terminal-side device to cancel the transmission of the first SR and to cancel suspension of the first SR, i.e., to end the suspended state of the first SR. Specifically referring to fig. 2A, after the terminal-side device sends the random access preamble to the network-side device, the terminal-side device cancels the suspended first SR at time T2. When the suspended first SR is suspended, if the terminal-side device does not trigger the first SR again, the terminal-side device will not be able to send the first SR. It should be understood that the time when the terminal-side device sends the random access preamble to the network-side device may coincide with the time T2, or there may be a time delay, which is not limited herein.
104. And the terminal side equipment receives the response message corresponding to the random access preamble from the network side equipment.
In this embodiment, after the terminal side device sends the random access preamble to the network side device, the network side device may receive the random access preamble sent by the terminal side device, and then the network side device sends a response message corresponding to the random access preamble to the terminal side device, where the response message corresponding to the random access preamble may indicate whether the network side device indicates the uplink resource to the terminal side device. When the response message does not indicate the uplink resource, the terminal side device performs step 105.
It should be noted that the response message corresponding to the random access preamble is not necessarily a random access response RAR, and may also include other information, which is described below:
firstly, when the response message indicates the uplink resource:
in this embodiment, when the response message received by the terminal side device indicates the uplink resource, the terminal side device transmits uplink data to the network side device by using the uplink resource indicated in the response message. At this time, if the amount of the uplink resource obtained by the terminal side device is sufficient to transmit uplink data, the terminal side device will not send the scheduling request SR to the network side device any more.
It should be understood that the uplink resource may be located in the random access response RAR in the response message, and the random access response RAR in the response message may also carry other information, for example, an indication about beam failure recovery, or system information SI, which is not limited herein.
Secondly, when the response message does not indicate the uplink resource:
in this embodiment, when the response message does not indicate the uplink resource, the response message may include other information to indicate how the terminal side device should process when the uplink resource is not received.
The response message comprises a random access response RAR:
in this embodiment, a response message sent by the network-side device to the terminal-side device does not include an uplink resource, but the response message includes a random access response RAR, where the random access response RAR includes indication information, and the indication information is used to indicate that the terminal-side device stops sending the first SR to the network-side device within a first duration, as shown in fig. 2B, where the first duration is a sum of an SR sending prohibition duration corresponding to the first SR and a first preset duration.
Specifically, when the terminal-side device receives a response message sent by the network-side device, the terminal-side device may know, by analyzing the content carried in the response message, that although the network-side device does not allocate the uplink resource to the terminal-side device, the random access response RAR includes indication information for configuring the first preset duration. The terminal side equipment can set a first preset time length according to the indication information, and further achieves the purpose of setting the first time length. It should be understood that the specific form of the indication information may vary according to the actual application environment, and the indication information may be one or a group of data packets for triggering the timer, or one or a group of data packets for carrying specific operation steps, which is not limited herein. In this embodiment and the following embodiments, only the indication information is taken as an example for description.
In this embodiment, the random access response RAR indicates the first preset duration, and specifically, the indication information in the random access response RAR may directly indicate the first preset duration. For example, the first preset duration is indicated as a waiting timer. At this time, the indication information may be a duration of a waiting timer, and may also be used as a trigger source for triggering the restart of the waiting timer.
Furthermore, the terminal side device may restart a waiting timer according to the indication information, and within a time range from the time when the waiting timer is restarted to the time when the waiting timer times out, the terminal side device stops retransmitting the first SR to the network side device. As shown in fig. 2C, the time t1 is the time when the terminal-side device receives the indication information in the random access response RAR. At this time, after the terminal-side device passes through an SR transmission prohibition duration, the terminal-side device may restart the wait timer. The time range from the restart of the waiting timer to the overtime of the undetermined timers is a first preset time length, and then the purpose of adjusting the first preset time length can be achieved by adjusting the time range from the restart of the waiting timer to the overtime of the undetermined timers. Since the first duration is the sum of the SR transmission prohibition duration corresponding to the first SR and the first preset duration, the purpose of adjusting the first duration can be achieved by adjusting the first preset duration. The duration of the waiting timer may be configured by the network side device, and certainly, since the waiting timer may differ according to different actual situations, the time set by the to-be-scheduled timers also differs according to different network qualities or specific requirements of the terminal side device, which is not limited herein.
In addition, the indication information in the random access response RAR may also directly indicate the number of SR configuration cycles when indicating the first preset duration, where the first preset duration is at least one time of the SR configuration cycle. It should be understood that the duration of a single SR configuration period may be equal to the SR transmission prohibition duration, or may be equal to the duration of other timers configured by the network side device, which is not limited herein. In this embodiment, the duration of the SR configuration period may be unchanged, so that when the network side device indicates the number of the SR configuration periods to the terminal side device, the first preset duration may be determined. It should be understood that the number of SR configuration cycles may be one or more, and is not limited herein. For the sake of understanding, the first preset duration is taken as 3 times the SR configuration period. As shown in fig. 2D, the time t1 is the time when the terminal side device receives the indication information that the network side device has placed in the random access response RAR, and at this time, after the terminal side device passes through one SR transmission prohibition duration, the terminal side device passes through 3 SR configuration cycles, so that the time t2 can be reached. Regarding time t2, it will be described in detail later, and detailed description thereof is omitted here.
(II), the response message comprises a random access response RAR and a media access control-control element MAC CE:
in this embodiment, the response message sent by the network-side device to the terminal-side device does not include the uplink resource, but includes the media access control-control element MAC CE in addition to the random access response RAR. The MAC CE includes indication information for configuring a first preset duration, where the indication information is used to indicate that the terminal side device stops retransmitting the first SR to the network side device within the preset first duration, as shown in fig. 2B, and the first duration is a sum of a SR transmission prohibition duration corresponding to the first SR and the first preset duration.
Specifically, when the terminal side device receives a response message sent by the network side device, the terminal side device may know by analyzing the content carried by the response message, although the network side device does not allocate the uplink resource to the terminal side device, and the network side device does not place the indication information in the random access response RAR but places the indication information in the media control unit information MAC CE, and the terminal side device may set the first preset duration according to the indication information, thereby achieving the purpose of setting the first duration. It should be understood that the indication information may be one or a group of data packets triggering the timer, and may also be one or a group of data packets carrying specific operation steps, which is not limited herein. In this embodiment and the following embodiments, only the indication information is taken as an example for description.
Similarly to the foregoing, the MAC CE indicates the first preset duration, specifically, the indication information in the MAC CE may directly indicate the first preset duration, for example, similar to fig. 2C, the first preset duration may be indicated as a waiting timer, and at this time, the indication information may be a duration of the waiting timer, and may also be used as a trigger source for triggering the restart of the waiting timer. Since the foregoing has been described in detail, it is not repeated here.
In addition, the indication information in the MAC CE may also directly indicate the number of SR configuration cycles when indicating the first preset duration, where the first preset duration is at least one time of the SR configuration cycle. This is similar to fig. 2D described above, and will not be described herein again.
105. And under the condition that the response message does not indicate the uplink resource, the terminal side equipment stops the retransmission of the first SR within the first duration.
It should be understood that the reason why the network-side device instructs the terminal-side device to stop retransmitting the first SR within the first duration through the indication information is that after the network-side device receives the first SR sent by the terminal-side device for the first time, the network-side device may know that the terminal-side device needs to acquire the uplink resource to transmit uplink data, however, the network-side device may not allocate the uplink resource to the terminal-side device immediately because other transactions need to be processed, or when the network-side device receives the first SR, the network-side device is poor in quality and prepares to allocate the uplink resource to the terminal-side device when the network quality is slightly better. Then, the network side device notifies the terminal side device by placing the indication information in the response message, and the network side device allocates uplink resources to the terminal side device possibly within the first duration, and requests the terminal side device to stop retransmitting the first SR within the first duration.
If the first duration is over time and the ue is not indicated by the network side device for the uplink resource, step 106 is executed.
106. And the terminal side equipment retransmits the first SR to the network side equipment.
In this embodiment, if the terminal side device does not receive the uplink resource allocated by the network side device within the first duration, at this time, in order to ensure a requirement for the terminal side device to send uplink data, the terminal side device may trigger the first SR again, and then send the first SR to the network side device to apply for the uplink resource. Specifically, referring to fig. 2A, when a first time length passes from T1 to T2, if the terminal-side device does not receive the uplink resource allocated by the network-side device within the first time length, the terminal-side device triggers the first SR at T3, and an area after T3 represents that the first SR is in a suspended state, so that the terminal-side device can send the first SR in the suspended state to the network-side device to apply for the uplink resource.
In this embodiment, after the terminal side device sends the first scheduling request SR to the network side device, the network side device may know that the terminal side device needs the uplink resource. If the response message received by the terminal side device and replied by the network side device does not indicate uplink resources, the terminal side device stops the retransmission of the first SR within the first duration. Therefore, the terminal side equipment is prevented from repeatedly requesting the network side equipment to allocate the uplink grant to the terminal side equipment within the first duration, so that the scheme can save SR resources, and interference generated among the SR resources within the first duration can be reduced due to the fact that SR transmission is reduced within the first duration.
In the above embodiment, the case that the indication information indicates that the terminal side device stops retransmitting the first scheduling request SR to the network side device within the first duration is described, but in practical applications, the network side device may also not send a response message carrying the indication information to the terminal side device, and instead, directly indicate that the terminal side device stops retransmitting the first SR to the network side device within the first duration through the response message. As will be described in detail below, referring to fig. 3 in particular, the steps executed by the terminal-side device and the network-side device include:
301. the terminal side equipment triggers the first SR, wherein the triggered first SR is in a suspended state.
In this embodiment, when the terminal side device needs to send uplink data to the network side device, the terminal side device may apply for an uplink resource to the network side device in a manner of a scheduling request SR. At this time, the terminal side device may trigger the first scheduling request SR, and after the terminal side device triggers the first SR, the first SR is in a suspended state, where the suspended state means that the terminal side device may directly send the first SR in the suspended state to the network side device without triggering another scheduling request. Specifically, similar to step 101, the detailed description is omitted here.
302. The terminal side equipment sends a first SR to the network side equipment.
In this embodiment, after the terminal side device triggers the first SR, the terminal side device may send the first SR to a network side device, where the first SR is used to request an uplink resource from the network side device. After the network side device receives the first SR, the network side device may know that the terminal side device needs to send uplink data. Similar to step 102, the detailed description is omitted here.
In this embodiment, after the terminal side device triggers the first SR, the first SR may be aligned with the time domain of the PUCCH immediately, or may have a certain time gap to be aligned with the time domain of the PUCCH, which is not limited herein. Therefore, in fig. 4, the time (time T1) when the terminal side device triggers the first SR may overlap with the time when the terminal side device transmits the first SR to the network side device, or a certain time gap may be reserved, which is not limited herein.
303. The terminal side equipment sends a random access preamble to the network side equipment.
In this embodiment, when the terminal side device does not successfully acquire the uplink resource through the first SR. For example, due to poor network quality, the network side device does not successfully allocate the uplink resource to the terminal side device, or, due to network delay, the network side device has not yet reached allocation of the uplink resource to the terminal side device, or, due to some other reason, the network side device has not yet reached allocation of the uplink resource to the terminal side device, which is not limited herein. At this time, the terminal side device sends a random access preamble to the network side device, where the random access preamble may be a random access preamble used for requesting uplink resources to the network side device, may also be a random access preamble related to beam failure recovery, and may also be a random access preamble requesting system information SI, which is not limited herein. Since the detailed description of step 103 is already provided above, detailed description thereof is omitted here.
It should be noted that the transmission of the various random access preambles described above will cause the terminal-side device to cancel the transmission of the first SR and to cancel suspension of the first SR, i.e., to end the suspended state of the first SR. Specifically referring to fig. 4, after the terminal-side device sends the random access preamble to the network-side device, the terminal-side device cancels the suspended first SR at time T2, and when the suspended first SR is cancelled, if the terminal-side device does not trigger the first SR again, the terminal-side device cannot send the first SR. It should be understood that the time when the terminal-side device sends the random access preamble to the network-side device may coincide with the time T2, or there may be a time delay, which is not limited herein.
304. And the terminal side equipment stops the timing of the SR transmission prohibition duration and initializes the transmission counter of the first SR.
In this embodiment, as shown in fig. 4, after the terminal-side device sends the random access preamble to the network-side device, the terminal-side device stops the timing of the SR transmission prohibition duration to prevent the first SR from being triggered due to the SR transmission prohibition duration being overtime. In addition, the terminal side device initializes the transmission counter of the first SR, that is, clears the transmission counter of the first SR and prepares to recount, so as to prevent the random access preamble requesting the uplink resource from being triggered when the number of transmissions accumulated in the transmission counter of the first SR reaches an upper limit.
In some possible implementations, the terminal side device may restart the timing of the transmission prohibition duration after sending the random access preamble to the network side device, so as to restart the timing of the transmission prohibition duration, thereby preventing the SR transmission prohibition duration from being overtime and triggering the transmission of the first SR.
305. And the terminal side equipment receives the response message corresponding to the random access preamble from the network side equipment.
In this embodiment, after the terminal side device sends the random access preamble to the network side device, the network side device may receive the random access preamble sent by the terminal side device. Then, the network side device sends a response message corresponding to the random access preamble to the terminal side device, where the response message corresponding to the random access preamble may indicate whether the network side device indicates uplink resources to the terminal side device. When the response message does not indicate the uplink resource, the terminal side device executes step 306.
In this embodiment, the response message corresponding to the random access preamble is a random access response RAR, and the random access response RAR may directly trigger and start the timing of the SR transmission prohibition duration. The random access response RAR may also directly indicate the first predetermined duration.
306. And under the condition that the response message does not indicate the uplink resource, the terminal side equipment stops the retransmission of the first SR within the first duration.
It should be understood that the reason why the network-side device instructs the terminal-side device to stop retransmitting the first SR within the first duration through the random access response RAR is that after the network-side device receives the first SR sent by the terminal-side device for the first time, the network-side device can know that the terminal-side device needs to acquire the uplink resource to transmit uplink data. However, the network side device may have other transactions to process and may not immediately allocate the uplink resource to the terminal side device, or when the network side device receives the first SR, the network quality is not good, and the network side device prepares to allocate the uplink resource to the terminal side device when the network quality is slightly better. Then, the network-side device notifies the terminal-side device through a random access response RAR, and the network-side device allocates uplink resources to the terminal-side device in the first duration, and requests the terminal-side device to stop retransmitting the first SR in the first duration. Therefore, after the terminal-side device receives the random access response RAR sent by the network-side device, the terminal-side device may directly trigger and start the timing of the SR transmission prohibition duration. Then, after the SR transmission prohibition duration is over time, the terminal side device may adjust the number of SR configuration cycles or adjust the first preset duration according to the indication of the random access response RAR, so as to achieve the purpose of adjusting the first duration. Specifically, similar to the previous step 104, the detailed description is omitted here.
307. And under the condition that the first time length is overtime and the terminal side equipment is not indicated by the network side equipment to the uplink resource, the terminal side equipment retransmits the first SR to the network side equipment.
In this embodiment, if the terminal side device does not receive the uplink resource allocated by the network side device within the first duration, at this time, in order to ensure a requirement for the terminal side device to send uplink data, the terminal side device may trigger the first SR again, and then send the first SR to the network side device to apply for the uplink resource. Similar to step 106, since the above description is provided in detail, the detailed description is omitted here.
In this embodiment, after the terminal side device sends the first scheduling request SR to the network side device, the network side device may know that the terminal side device needs the uplink resource. If the response message received by the terminal side device and replied by the network side device does not indicate uplink resources, the terminal side device stops the retransmission of the first SR within the first duration. Therefore, the terminal side equipment is prevented from repeatedly requesting the network side equipment to allocate the uplink authorization to the terminal side equipment within the first duration, so that the scheme can save SR resources, and the interference generated among the SR resources within the first duration is reduced because the SR transmission is reduced within the first duration.
In addition to the above embodiments, in practical applications, the terminal side device may also send other messages to request the network side device for uplink resources, for example, the second SR with higher priority. As will be described in detail below, with reference to fig. 5 in particular, the steps performed by the terminal-side device and the network-side device include:
501. the terminal side equipment triggers the first SR, wherein the triggered first SR is in a suspended state.
In this embodiment, when the terminal side device needs to send uplink data to the network side device, the terminal side device may apply for an uplink resource to the network side device in a manner of a scheduling request SR. At this time, the terminal side device may trigger the first scheduling request SR, and after the terminal side device triggers the first SR, the first SR is in a suspended state, where the suspended state means that the terminal side device may directly send the first SR in the suspended state to the network side device without triggering another scheduling request. Specifically, similar to step 101, the detailed description is omitted here.
502. The terminal side equipment transmits a first SR to the network side equipment.
In this embodiment, after the terminal side device triggers the first SR, the terminal side device may send the first SR to a network side device, where the first SR is used to request an uplink resource from the network side device. After the network side device receives the first SR, the network side device may know that the terminal side device needs to send uplink data. Similar to step 102, the detailed description is omitted here.
503. The terminal side equipment sends a random access preamble to the network side equipment.
In this embodiment, when the terminal side device does not successfully acquire the uplink resource through the first SR, for example, due to poor network quality, the network side device does not successfully allocate the uplink resource to the terminal side device, or due to network delay, the network side device has not yet reached to allocate the uplink resource to the terminal side device, or due to some other reasons, the network side device has not yet reached to allocate the uplink resource to the terminal side device, which is not limited herein. At this time, the terminal side device sends a random access preamble to the network side device, where the random access preamble may be a random access preamble used for requesting uplink resources to the network side device, may also be a random access preamble related to beam failure recovery, and may also be a random access preamble requesting system information SI, and is not limited herein. Since the detailed description of step 103 is already provided above, detailed description thereof is omitted here.
504. And the terminal side equipment receives the response message corresponding to the random access preamble from the network side equipment.
In this embodiment, after the terminal side device sends the random access preamble to the network side device, the network side device may receive the random access preamble sent by the terminal side device. Then, the network side device sends a response message corresponding to the random access preamble to the terminal side device, where the response message corresponding to the random access preamble may indicate whether the network side device indicates uplink resources to the terminal side device. When the response message does not indicate the uplink resource, the terminal-side device performs step 505.
505. And under the condition that the response message does not indicate the uplink resource, the terminal side equipment stops the retransmission of the first SR within the first duration.
It should be understood that the reason why the network-side device instructs the terminal-side device to stop retransmitting the first SR within the first duration through the random access response RAR is that after the network-side device receives the first SR sent by the terminal-side device for the first time, the network-side device can know that the terminal-side device needs to acquire the uplink resource to transmit uplink data. However, the network side device may have other transactions to process and may not immediately allocate the uplink resource to the terminal side device, or when the network side device receives the first SR, the network quality is not good, and the network side device prepares to allocate the uplink resource to the terminal side device when the network quality is slightly better. Then, the network-side device notifies the terminal-side device through a random access response RAR, and the network-side device allocates uplink resources to the terminal-side device in the first duration, and requests the terminal-side device to stop retransmitting the first SR in the first duration. Therefore, after the terminal-side device receives the random access response RAR sent by the network-side device, the terminal-side device may directly trigger and start the timing of the SR transmission prohibition duration. Then, after the SR transmission prohibition duration is over time, the terminal side device may adjust the number of SR configuration cycles or the duration of the wait timer according to the indication of the random access response RAR to adjust the first preset duration, thereby achieving the purpose of adjusting the first duration. Specifically, similar to the previous step 104, the detailed description is omitted here.
506. And under the condition that the response message does not indicate the uplink resource, the terminal side equipment sends a second SR to the network side equipment, wherein the priority of the second SR is higher than that of the first SR.
In this embodiment, when the response message does not indicate uplink resources, the terminal side device may further send a second SR to the network side device, where the priority of the second SR is higher than that of the first SR, in addition to stopping retransmission of the first SR within the first duration. It should be understood that the second SR has a higher priority than the first SR means that when the network side device is faced with a decision between handling a first SR of normal priority and handling a second SR of high priority, the network side device will preferentially handle the second SR.
Specifically, the terminal side device sends the second SR to the network side device after a second duration, where the second duration is a duration greater than or equal to zero. As shown in fig. 6A, when the second duration is equal to zero, it indicates that the terminal-side device triggers the second SR when the terminal-side device receives the response message sent by the network-side device and determines that the response message does not indicate uplink resources. Then, the second SR is in a suspended state, and the terminal-side device transmits the second SR to the network-side device at time T4. It should be understood that, in fig. 6A, the time when the network-side device sends the response message to the terminal-side device and the time when the terminal-side device sends the second SR to the network-side device (time T4) may coincide, or there may be a reasonable network delay, which is not limited herein.
As shown in fig. 6B, when the second duration is non-zero duration between T3 and T4 in the figure, after the terminal-side device receives the response message sent by the network-side device, the terminal-side device triggers timing of the second duration, and after the second duration, the terminal-side device triggers the second SR, so that the second SR is in a suspended state, and then the terminal-side device sends the second SR to the network-side device at time T5.
It should be noted that, in this embodiment, the step 505 and the step 506 are not limited in time sequence, and the terminal side device may first execute the step 505 and then execute the step 506, or may first execute the step 506 and then execute the step 505, which is not limited herein.
In this embodiment, after the terminal side device sends the first scheduling request SR to the network side device, the network side device may know that the terminal side device needs the uplink resource. If the response message received by the terminal side device and replied by the network side device does not indicate uplink resources, the terminal side device stops the retransmission of the first SR within the first duration. And the terminal side device sends a second SR with higher priority to the network side device, so that the terminal side device is prevented from repeatedly requesting the network side device to allocate uplink grant to the terminal side device within the first duration, and the network side device can preferentially allocate uplink resources to the terminal side device. Therefore, the scheme can save SR resources, and the interference generated among the SR resources is reduced because the transmission of the SR within the first duration is reduced.
In the above embodiment, after the terminal side device transmits the random access preamble to the network side device, the terminal side device will end the suspend state of the first SR. However, in this embodiment, an implementation is proposed that can save the scheduling request resource without cancelling suspending the first SR. As will be described in detail below, with reference to fig. 7 in particular, the steps performed by the terminal-side device and the network-side device include:
701. the terminal side equipment triggers the first SR, wherein the triggered first SR is in a suspended state.
In this embodiment, when the terminal side device needs to send uplink data to the network side device, the terminal side device may apply for an uplink resource to the network side device in a manner of a scheduling request SR. At this time, the terminal side device may trigger the first scheduling request SR, and after the terminal side device triggers the first SR, the first SR is in a suspended state, where the suspended state means that the terminal side device may directly send the first SR in the suspended state to the network side device without triggering another scheduling request. Specifically, similar to step 101, the detailed description is omitted here.
702. The terminal side equipment transmits a first SR to the network side equipment.
In this embodiment, after the terminal side device triggers the first SR, the terminal side device may send the first SR to a network side device, where the first SR is used to request an uplink resource from the network side device. After the network side device receives the first SR, the network side device may know that the terminal side device needs to send uplink data. Similar to step 102, the detailed description is omitted here.
703. The terminal side equipment sends a random access preamble to the network side equipment.
In this embodiment, when the terminal side device does not successfully acquire the uplink resource through the first SR, for example, due to poor network quality, the network side device does not successfully allocate the uplink resource to the terminal side device, or due to network delay, the network side device has not yet reached to allocate the uplink resource to the terminal side device, or due to some other reasons, the network side device has not yet reached to allocate the uplink resource to the terminal side device, which is not limited herein. At this time, the terminal side device sends a random access preamble to the network side device, where the random access preamble may be a random access preamble used for requesting uplink resources to the network side device, may also be a random access preamble related to beam failure recovery, and may also be a random access preamble requesting system information SI, and is not limited herein. Since the detailed description of step 103 is already provided above, detailed description thereof is omitted here.
704. The terminal-side device maintains the suspended state of the first SR.
In this embodiment, after the terminal-side device sends the random access preamble to the network-side device, the terminal-side device will not cancel suspending the first SR, that is, the terminal-side device will keep the suspended state of the first SR. Therefore, if the terminal-side device needs to send the first SR again, the terminal-side device does not need to trigger the first SR again. As shown in fig. 8, after the terminal side device triggers the first SR at time T1, the first SR remains in the suspended state until the network side device allocates uplink resources for the terminal side device.
705. And the terminal side equipment receives the response message corresponding to the random access preamble from the network side equipment.
In this embodiment, after the terminal side device sends the random access preamble to the network side device, the network side device may receive the random access preamble sent by the terminal side device. Then, the network side device sends a response message corresponding to the random access preamble to the terminal side device, where the response message corresponding to the random access preamble may indicate whether the network side device indicates uplink resources to the terminal side device. When the response message does not indicate the uplink resource, the terminal side device executes step 706.
706. And under the condition that the response message does not indicate the uplink resource, the terminal side equipment stops the retransmission of the first SR within the first duration.
It should be understood that the reason why the network-side device instructs the terminal-side device to stop retransmitting the first SR within the first duration through the random access response RAR is that after the network-side device receives the first SR sent by the terminal-side device for the first time, the network-side device may know that the terminal-side device needs to acquire the uplink resource to transmit uplink data, but the network-side device may have other transactions to process and cannot immediately allocate the uplink resource to the terminal-side device, or when the network-side device receives the first SR, the network-side device has poor quality and is ready to allocate the uplink resource to the terminal-side device when the network quality is slightly better. Then, the network-side device notifies the terminal-side device through a random access response RAR, and the network-side device allocates uplink resources to the terminal-side device in the first duration, and requests the terminal-side device to stop retransmitting the first SR in the first duration. Therefore, after the terminal-side device receives the random access response RAR sent by the network-side device, the terminal-side device may directly trigger and start the timing of the SR transmission prohibition duration. Then, after the SR transmission prohibition duration is over time, the terminal side device may adjust the number of SR configuration cycles or adjust the first preset duration according to the indication of the random access response RAR, so as to achieve the purpose of adjusting the first duration. Specifically, similar to the previous step 104, the detailed description is omitted here.
707. If the terminal-side device is not indicated by the network-side device for the uplink resource, the terminal-side device retransmits the first SR in the suspended state to the network-side device.
In this embodiment, if the terminal side device receives the response message sent by the network side device and after the first time length elapses, the network side device does not allocate uplink resources to the terminal side device, and then the terminal side device retransmits the first SR in the suspended state to the network side device.
In this embodiment, after the terminal side device sends the first scheduling request SR to the network side device, the network side device may know that the terminal side device needs the uplink resource. If the response message received by the terminal side device and replied by the network side device does not indicate uplink resources, the terminal side device stops the retransmission of the first SR within the first duration. Therefore, the terminal side equipment is prevented from repeatedly requesting the network side equipment to allocate the uplink authorization to the terminal side equipment within the first duration, and the terminal side equipment directly sends the first SR in the suspended state to the network side after the first duration is finished, so that SR resources can be saved, and interference generated among SR resources within the first duration is reduced due to reduction of sending of SRs within the first duration.
