It is described in detail to one step, it is clear that the described embodiments are only some of the embodiments of the present invention, rather than whole implementation
Example.Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
All other embodiment, shall fall within the protection scope of the present invention.
As described in Figure 1, the method for transmission of embodiment of the present invention scheduling request includes:
Step 100, terminal are having multiple SR to need to send, and when the multiple SR corresponds to different SR configuration, from described
A set of SR is selected to configure in the corresponding more set SR configurations of multiple SR;
Step 101, the terminal configure corresponding SR resource by the SR of selection and carry out SR transmission.
The terminal of the embodiment of the present invention is having multiple SR to need to send, and when the multiple SR corresponds to different SR configuration,
Select a set of SR to configure from the corresponding more set SR configurations of the multiple SR, and by the SR of selection configure corresponding SR resource into
Row SR is sent.Since the terminal of the embodiment of the present invention can select a set of SR configuration simultaneously from the corresponding more set SR configurations of multiple SR
Corresponding SR resource is configured by the SR of selection and carries out SR transmission, sends SR to realize under the mostly scene of set SR configuration,
Further avoid frequent SR report and base station scheduling resource waste.
The mode that the terminal of that embodiment of the invention selects a set of SR to configure from the corresponding more set SR configurations of the multiple SR has
Very much, it for example randomly chooses.
Optionally, the embodiment of the present invention provides several feasible and relatively good effect selection mode, is said separately below
It is bright.
Selection mode one, the terminal select to be worked as with SR resource distance from the corresponding more set SR configurations of the multiple SR
The preceding moment it is nearest SR configuration.
Every set SR configuration can all have corresponding SR resource, and SR resource here includes time-domain resource and/or frequency domain money
Source.
For selection mode one, terminal it needs to be determined that every set SR configures corresponding available SR resource, then therefrom find away from
The available SR resource nearest from current time, and select the corresponding SR configuration of the available SR resource found.
Selection mode two, the terminal selection SR configuration period from the multiple SR corresponding more set SR configurations are shortest
SR configuration.
Every set SR configuration can all have the configuration period of corresponding SR resource, and the SR resource distribution period here refers to one
Cover the time interval that SR frequency domain resource occurs in SR configuration.For example multiple SR frequency domain resources are with the 1ms period in a set of SR configuration
Occur, then the configuration period of SR resource is exactly 1ms.
For selection mode two, terminal configures the period it needs to be determined that every set SR configures corresponding SR, then therefrom finds most
Short SR configures the period, and selects the corresponding SR configuration of the SR found configuration period.
The selection from the multiple SR corresponding more set SR configurations of selection mode three, the terminal triggers SR and priority
The corresponding SR configuration of highest logic channel.
In an implementation, each logic channel can have respective priority, and every set SR configuration can correspond to a logic letter
Road.
Based on this, for selection mode three, terminal it needs to be determined that each logic channel priority, then therefrom find touching
The logic channel of SR and highest priority has been sent out, and has selected the corresponding SR configuration of the logic channel found.
Selection triggers SR from the multiple SR corresponding more set SR configurations and time delay is wanted for selection mode four, the terminal
Ask the corresponding SR configuration of highest logic channel.
In an implementation, each logic channel can have respective time delay, and every set SR configuration can correspond to a logic channel.
Based on this, for selection mode four, terminal it needs to be determined that each logic channel time delay, then therefrom find triggering
SR and the highest logic channel of delay requirement, and select the corresponding SR configuration of the logic channel found.
Wherein, every set SR configuration can all have a SR to forbid timer (sr-ProhibitTimer).
Optionally, after the terminal configures corresponding SR resource progress SR transmission by the SR of selection, the terminal exists
The SR that SR sending instant restarts the corresponding SR configuration of all pending (hang-up) SR forbids timer.
Wherein, pending SR is the SR for being triggered, and receiving base station resource allocation not yet.
As long as that is, there is SR transmission, so that it may restart more set SR and configure corresponding sr-ProhibitTimer.
Wherein, it when the terminal configures corresponding SR resource progress SR transmission by the SR of selection, is configured in the SR of selection
Corresponding SR resource carries out SR transmission after reaching.
Optionally, it is carried out in SR transmission process if configuring corresponding SR resource by the SR of selection, the terminal is selected again
New SR configuration is selected, then the SR selected before stopping at configures the SR in corresponding SR resource and sends, and by set SR configuration pair
DSR (specific schedule request) the transmission times counter answered is set to initial value, such as 0.
Than configuring 2 and SR configuration 3 if any SR configuration 1, SR.Terminal selects the corresponding SR resource of SR configuration 2 to send SR, is sending out
During sending SR, if terminal has higher preferential SR triggering, selection criterion is configured according to SR, SR has been selected to configure 3 again,
Then terminal stops at the corresponding SR resource of SR configuration 2 and sends SR, and sends SR in the corresponding SR resource of SR configuration 3.
Two examples are set forth below, describe in detail to the solution of the present invention.
Embodiment 1:
Multiple SR need to send in the present embodiment, but the SR for hanging up (pending) carries out SR transmission not yet.
Such as:
T1 moment, the buffer area of UE are sky.
T2 moment, UE have eMBB (eMBB) data to reach (using logic channel 1), trigger Regular (routine) at this time
BSR, but there is no UL grant, to trigger SR.
But not yet reached since the relevant SR of logic channel 1 configures corresponding SR resource, SR is in pending shape
State, there is no send;
The T3 moment has URLLC (superelevation is reliable and low delay communicates) data of higher priority to reach and (use logic channel
2) it, triggers Regular BSR again at this time, but there is no UL grant, to trigger SR.
There are two the SR of pending for terminal at this time.
If logic channel 1 and the corresponding SR of logic channel 2 configuration are different, since terminal does not support parallel SR, then just
It needs to select to configure corresponding SR resource using any set SR and carries out SR transmission, Specific Principles can be there are several types of:
Selection can be nearest apart from current time with SR resource from the multiple SR corresponding more set SR configurations for the terminal
SR configuration;Or
Terminal selection SR configuration period shortest SR configuration from the corresponding more set SR configurations of the multiple SR;Or
Terminal selection from the corresponding more set SR configurations of the multiple SR triggers the logic of SR and highest priority
The corresponding SR configuration of channel;Or
Terminal selection from the corresponding more set SR configurations of the multiple SR triggers SR and delay requirement is highest patrols
Collect the corresponding SR configuration of channel.
According to one of mentioned above principle, terminal has selected SR with postponing, and reaches when the SR of selection configures corresponding SR resource, then
It is configured in the SR of selection and carries out SR transmission in corresponding SR resource.
Once SR is sent, needs to restart simultaneously logic channel 1 and the relevant SR of logic channel 2 configures corresponding sr-
ProhibitTimer。
Embodiment 2:
Terminal has SR to trigger and has sent in the present embodiment, but does not receive UL grant.The SR is at this time
Pending state, terminal has new SR triggering again at this time.
Such as:
T1 moment, the buffer area of UE are sky.
T2 moment, UE have eMBB data to reach (using logic channel 1), trigger Regular BSR at this time, but do not have UL
Grant, to trigger SR.
It is reached when the relevant SR of logic channel 1 configures corresponding SR resource, terminal sends SR by the resource and starting should
SR configures corresponding sr-ProhibitTimer.But terminal never receives UL grant, therefore the SR is in pending
State.
The T3 moment has the URLLC data of higher priority to reach (using logic channel 2), triggers Regular again at this time
BSR, but there is no UL grant, to trigger SR.
There are two the SR of pending for terminal at this time.
If logic channel 1 and the corresponding SR of logic channel 2 configuration are different, since terminal does not support parallel SR, then just
It needs to select to configure corresponding SR resource using any set SR and carries out SR transmission, Specific Principles can be there are several types of:
Selection can be nearest apart from current time with SR resource from the multiple SR corresponding more set SR configurations for the terminal
SR configuration;Or
Terminal selection SR configuration period shortest SR configuration from the corresponding more set SR configurations of the multiple SR;Or
Terminal selection from the corresponding more set SR configurations of the multiple SR triggers the logic of SR and highest priority
The corresponding SR configuration of channel;Or
Terminal selection from the corresponding more set SR configurations of the multiple SR triggers SR and delay requirement is highest patrols
Collect the corresponding SR configuration of channel.
According to one of mentioned above principle, if terminal has selected the corresponding SR of logic channel 2 to configure, terminal, which needs to terminate, is patrolled
The corresponding SR of channel 1 transmission is collected, and dsr-TransMax=0 is set.
Once new SR is sent, needs to restart simultaneously logic channel 1 and the relevant SR of logic channel 2 configuration is corresponding
sr-ProhibitTimer。
