Description

Method and device for transmitting scheduling request

The present application claims priority to Chinese Patent Application No. 200911070745.5, entitled "A Method and Apparatus for Sending Scheduling Requests", filed on November 3, 2017, the entire contents of which are incorporated herein by reference. In the application.

Technical field

The present invention relates to the field of wireless communication technologies, and in particular, to a method and device for transmitting a scheduling request.

Background technique

The Long Term Evolution (LTE) system is a scheduling-based system. The base station allocates time-frequency resources required for data transmission to the terminal device, and the terminal performs downlink data reception or uplink data transmission according to the scheduling command of the base station. The uplink data transmission is scheduled by the base station, and the base station scheduler notifies the terminal by using an uplink grant permission (UL grant) after determining the uplink resource allocation situation. The basis for the uplink resource allocation by the base station scheduler is the amount of uplink data to be sent by the terminal, that is, the buffer status of the terminal. The buffer is on the terminal side. If the base station wants to know the information, the terminal needs to perform a buffer status report (BSR) to the base station.

The New Radio (NR) system physical layer supports multiple numerology/TTI. Numerology is a term for the 3rd Generation Partnership Project (3GPP) Radio Access Network (RAN)1, which can be translated into baseband parameters. The main difference between different numerologies is that the subcarrier spacing supported by different numerology is different. For example, the subcarrier spacing supported by the 5G NR system includes at least: 15 kHz, 60 kHz, and the numerology corresponding to the two different subcarrier spacings is two independent numerologies.

Transmission Time Interval (TTI). In a traditional LTE system, the TTI length is 1 ms. Starting from LTE R14, in order to support delay reduction, different TTI lengths, such as one Orthogonal Frequency Division Multiplexing (OFDM) symbol length, are introduced.

For the NR system, the numerology and/or TTI corresponding to a bearer/logical channel is configured through the network. The numerology and/or TTI corresponding to different logical channels may be the same or different. For the uplink, the scheduling request (SR) information needs to reflect the numerology and /TTI corresponding to the logical channel that currently has the data transmission requirement, so that the network side device can perform reasonable uplink resource allocation according to the SR, in order to achieve this. The goal is to introduce multiple sets of SR configurations.

In an LTE system, the SR configuration is terminal-based, and one terminal has only one SR configuration. However, for the NR system, since the SR configurations corresponding to different logical channels may be different, there is currently no specific solution for how to perform SR transmission in a scenario where multiple sets of SR configurations exist.

The present invention will be further described in detail with reference to the accompanying drawings, in which . All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

As shown in FIG. 1 , a method for sending a scheduling request according to an embodiment of the present invention includes:

Step 100: When a terminal needs to send multiple SRs, and the multiple SRs correspond to different SR configurations, select a set of SR configurations from multiple sets of SR configurations corresponding to the multiple SRs.

Step 101: The terminal performs SR transmission by using the SR resource corresponding to the selected SR configuration.

In the embodiment of the present invention, the terminal selects a set of SR configurations from multiple sets of SR configurations corresponding to the multiple SRs, such as random selection.

Optionally, the embodiments of the present invention provide several feasible and effective selection methods, which are separately described below.

The first mode is that the terminal selects an SR configuration in which the available SR resources are closest to the current time from the multiple sets of SR configurations corresponding to the multiple SRs.

Each set of SR configurations has its own corresponding SR resources, where the SR resources include time domain resources and/or frequency domain resources.

For the first mode, the terminal needs to determine the available SR resources corresponding to each set of SR configurations, and then finds the available SR resources that are closest to the current time, and selects the SR configuration corresponding to the available available SR resources.

The second mode is that the terminal selects the SR configuration with the shortest SR configuration period from the multiple sets of SR configurations corresponding to the multiple SRs.

Each SR configuration has its own configuration period of the corresponding SR resources. The SR resource configuration period here refers to the interval at which the SR frequency domain resources appear in a set of SR configurations. For example, in a set of SR configurations, multiple SR frequency domain resources appear in a 1 ms period, and the SR resource configuration period is 1 ms.

For the second mode, the terminal needs to determine the SR configuration period corresponding to each set of SR configurations, and then find the shortest SR configuration period and select the SR configuration corresponding to the found SR configuration period.

In the third mode, the terminal selects an SR configuration corresponding to the logical channel with the highest priority and the highest priority, from the multiple sets of SR configurations corresponding to the multiple SRs.

In implementation, each logical channel will have its own priority, and each SR configuration will correspond to one logical channel.

Based on this, for the third mode, the terminal needs to determine the priority of each logical channel, and then finds the logical channel that triggers the SR and has the highest priority, and selects the SR configuration corresponding to the found logical channel.

In the fourth mode, the terminal selects an SR configuration corresponding to the logical channel that triggers the SR and has the highest delay requirement from the multiple sets of SR configurations corresponding to the multiple SRs.

In the implementation, each logical channel will have its own delay, and each SR configuration will correspond to one logical channel.

Based on this, for the fourth mode, the terminal needs to determine the delay of each logical channel, and then finds the logical channel that triggers the SR and has the highest delay requirement, and selects the SR configuration corresponding to the found logical channel.

Among them, each SR configuration will have an SR disable timer (sr-ProhibitTimer).

Optionally, after the terminal sends the SR by using the SR resource corresponding to the selected SR configuration, the terminal restarts the SR-disabled timer of the SR configuration corresponding to all pending (suspended) SRs at the time of the SR sending.

The pending SR is an SR that is triggered and has not received the base station resource allocation.

In other words, as long as there is SR transmission, you can restart the sr-ProhibitTimer corresponding to multiple sets of SR configurations.

When the terminal performs SR transmission by using the SR resource corresponding to the selected SR configuration, the SR transmission is performed after the SR resource corresponding to the selected SR configuration arrives.

Optionally, if the terminal reselects a new SR configuration by using the SR resource corresponding to the selected SR configuration, the terminal stops the SR transmission on the SR resource corresponding to the previously selected SR configuration, and the The dedicated scheduling request (DSR) transmission count counter corresponding to the SR configuration is set to an initial value, such as 0.

For example, there are SR configuration 1, SR configuration 2, and SR configuration 3. The terminal selects the SR resource corresponding to the SR configuration 2 to send the SR. In the process of sending the SR, if the terminal has a higher priority SR trigger, and the SR configuration 3 is reselected according to the SR configuration selection criterion, the terminal stops in the SR configuration 2. The SR resource sends an SR, and the SR is sent in the SR resource corresponding to the SR configuration 3.

The scheme of the present invention will be described in detail below by exemplifying two examples.

Example 1:

In this embodiment, multiple SRs need to be sent, but the pending SR has not yet performed SR transmission.

such as:

At time T1, the UE's buffer is empty.

At time T2, the UE has eMBB (eMBB) data arriving (using logical channel 1), at which point the Regular (normal) BSR is triggered, but there is no UL grant, thus triggering the SR.

However, since the SR resource corresponding to the SR configuration related to the logical channel 1 has not arrived yet, the SR is in the pending state and is not sent;

At time T3, a higher priority URLLC (Ultra High Reliable and Low Latency Communication) data arrives (using logical channel 2), at which point the Regular BSR is triggered again, but there is no UL grant, which triggers the SR.

At this point, the terminal has two pending SRs.

If the SR configuration of the logical channel 1 and the logical channel 2 are different, the terminal does not support the parallel SR. Then, you need to select which SR to configure the corresponding SR resources for SR transmission. The specific principles are as follows:

According to one of the above principles, after the terminal selects the SR configuration, when the SR resource corresponding to the selected SR configuration arrives, the SR is sent on the SR resource corresponding to the selected SR configuration.

Once the SR transmits, it is necessary to simultaneously restart the sr-ProhibitTimer corresponding to the SR configuration associated with logical channel 1 and logical channel 2.

Example 2:

In this embodiment, the terminal has an SR trigger and has sent, but has not received the UL grant. At this time, the SR is in the pending state, and the terminal has a new SR trigger.

such as:

At time T1, the UE's buffer is empty.

At time T2, the UE has eMBB data arriving (using logical channel 1), at which point the Regular BSR is triggered, but there is no UL grant, thus triggering the SR.

When the SR resource corresponding to the SR configuration related to the logical channel 1 arrives, the terminal sends the SR through the resource and starts the sr-ProhibitTimer corresponding to the SR configuration. However, the terminal has not received the UL grant, so the SR is in the pending state.

At time T3, there is a higher priority URLLC data arrival (using logical channel 2), at which point the Regular BSR is triggered again, but there is no UL grant, thus triggering the SR.

At this point, the terminal has two pending SRs.

According to one of the above principles, if the terminal selects the SR configuration corresponding to the logical channel 2, the terminal needs to terminate the SR transmission corresponding to the logical channel 1, and set dsr-TransMax=0.

Once the new SR is sent, it is necessary to simultaneously restart the sr-ProhibitTimer corresponding to the SR configuration associated with logical channel 1 and logical channel 2.
