Detailed Description
As will be appreciated by those skilled in the art, as a matter of background, the prior art fails to provide a suitable processing scheme for processing the SR configuration associated with the released LCH, and in practical applications, resources are easily wasted.
In order to solve the above technical problem, an embodiment of the present invention provides a method for processing SR configuration, including: receiving indication information for releasing LCH; in response to the LCH being released, processing an SR configuration that has a mapping relationship with the LCH. Those skilled in the art understand that the user equipment adopting the solution of the embodiment of the present invention can reasonably process the SR configuration having a mapping relationship (also referred to as an association relationship) with the LCH when the LCH is released, so that the resource of the SR configuration having a mapping relationship with the LCH can be effectively used by other LCHs or the user equipment, thereby improving the resource utilization rate and avoiding resource waste.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Fig. 1 is a flowchart of a processing method for configuring a Scheduling Request (SR) according to a first embodiment of the present invention. The scheme of this embodiment may be applied to a User Equipment (UE for short) side, so as to improve the overall resource utilization of the network.
Specifically, in this embodiment, the method for processing the SR configuration may include the following steps:
step S101, receiving indication information for releasing a Logical Channel (LCH).
Step S102, responding to the LCH being released, and processing SR configuration having mapping relation with the LCH.
More specifically, the LCH may be used for transport traffic. For example, the ue may establish a plurality of services, and the plurality of services may correspond to a plurality of LCHs.
Further, one or more LCHs can be associated with the same SR configuration, or there can be LCHs that are not associated with any SR configuration.
Further, in this embodiment, the SR configuration may have a one-to-one mapping relationship with the released LCH.
Or, except the LCH indicated by the indication information, all other LCHs associated with the SR configuration are released at the same time. For example, the SR configuration may have a one-to-many mapping relationship with a plurality of LCHs, each of which is established by the user equipment. Further, for the SR configuration associated with the LCH that needs to be released and is indicated by the indication information, when all other LCHs associated with the SR configuration are released by the base station at the same time, the technical solution of this embodiment may also be used.
Those skilled in the art understand that, based on the foregoing scenario, the resource of the SR configuration is still nominally in an allocated state but actually is in an idle state (because all LCHs having mapping relationships with the SR configuration are released), so the SR configuration needs to be reasonably processed by the scheme of this embodiment to ensure that the SR configuration can be actually and effectively utilized, and resource waste is avoided.
Further, the SR configuration may include SR periods on multiple partial Bandwidths (BWPs) and corresponding Physical Uplink Control Channel (PUCCH) resource locations, that is, one SR configuration may include information on the SR periods on the BWPs in the serving cell and the PUCCH resource locations on the BWPs, and the SR periods on different BWPs may be the same or different. Further, each BWP may contain an upstream BWP and a downstream BWP. Those skilled in the art understand that the introduction of BWP may facilitate the user equipment to access only a portion of a large broadband serving cell, thereby effectively reducing the power consumption of the user equipment.
Preferably, the PUCCH resource position may include a frequency domain position of the PUCCH in different BWPs, i.e., an occupied symbol number, a symbol position, and the like.
In a typical application scenario, for a user equipment in a connected state in NR, a corresponding serving cell may include 3 BWPs (hereinafter referred to as BWP1, BWP2, and BWP3), where BWP1 is the currently activated BWP of the user equipment, that is, the user equipment may transmit a scheduling request on BWP1 using a PUCCH resource corresponding to BWP1 based on an SR period corresponding to BWP 1.
Further, the user equipment may establish a plurality of LCHs (e.g., LCH1, LCH2, and LCH3) for data transmission. Wherein:
the SR configuration associated with the LCH1 (hereinafter referred to as SR configuration 1) may include: an SR period over BWP1 and a PUCCH resource location for transmitting an SR over BWP 1; an SR period over BWP2 and a PUCCH resource location for transmitting an SR over BWP 2; and SR period on BWP3 and PUCCH resource location to transmit SR on BWP 3. Preferably, the SR cycle of the SR configuration 1 on BWP1, BWP2 and BWP3 may be the same or different.
The SR configuration associated with the LCH2 and LCH3 (hereinafter referred to as SR configuration 2) may include: an SR period over BWP1 and a PUCCH resource location for transmitting an SR over BWP 1; an SR period over BWP2 and a PUCCH resource location for transmitting an SR over BWP 2; and an SR period over BWP3 and a PUCCH resource location for transmitting an SR over the BWP 3. Preferably, SR configuration 2 may have the same or different SR periods on BWP1, BWP2 and BWP 3.
Preferably, in this application scenario, the SR configuration 1 and the LCH1 may be understood as having a one-to-one mapping relationship; the SR configuration 2 and the LCH2 and LCH3 are understood to have a one-to-many mapping relationship.
Further, when the LCH1 is released (e.g., released by the base station without data transmission), the ue adopting the scheme of this embodiment may process the SR configuration 1 having a one-to-one mapping relationship with the LCH1 based on the following implementation manner, so as to improve the utilization of the resources of the SR configuration 1 and avoid the waste of resources.
As a non-limiting example, the step S102 may include: and releasing the SR configuration with the mapping relation with the LCH. That is, in the present application scenario, in response to the LCH1 being released, the user equipment may release the SR configuration 1, so that the PUCCH resources on BWP1, BWP2 and BWP3 included in the SR configuration 1 can all be used by other LCHs or user equipments.
As another non-limiting embodiment, the step S102 may further include: and in the SR configuration with the mapping relation with the LCH, releasing the SR configuration on the currently activated BWP and reserving the SR configuration on other BWPs. That is, in the present application scenario, in response to the LCH1 being released, the user equipment may release PUCCH resources and other related SR configurations on BWP1 in the SR configuration 1, while leaving PUCCH resources and other related configurations on BWP2 and BWP3, so as to cope with the possibility of future base station switching the user equipment to BWP2 or BWP 3.
Further, the reserved SR configuration (e.g. PUCCH resources on BWP2 and BWP3 and other related configurations) may be used by other LCHs that the ue later establishes. As still another non-limiting embodiment, the step S102 may further include: suspending the SR configuration having a mapping relation with the LCH so that the SR configuration is in a known but unavailable state for a user equipment. That is, in the present application scenario, in response to the LCH1 being released, the user equipment may suspend the SR configuration 1, at which time, the user equipment may not delete the information related to the SR configuration 1, but the user equipment cannot transmit a scheduling request using PUCCH resources on the SR configuration 1 (including PUCCH resources on the BWP1, BWP2 to BWP 3).
As still another non-limiting example, the step S102 may further include: reserving SR configuration with a mapping relation with the LCH; recording the priority of the SR configuration; and when other LCHs have uplink data transmission requirements, judging whether to use the SR configuration to transmit the scheduling request according to a comparison result between the priority of the other LCHs and the priority of the SR configuration, wherein the other LCHs are not related to any SR configuration. Preferably, the other LCHs may be LCHs established by the user equipment after releasing the LCHs in response to the indication information, or LCHs already established before releasing the LCHs, as long as the LCHs are not associated with any SR configuration.
That is, in the present application scenario, in response to the LCH1 being released, the user equipment may retain (may also be referred to as save) the SR configuration 1 and record the priority of the SR configuration 1.
Further, the ue creates a new LCH (hereinafter referred to as LCH4) and the bs does not set associated SR configuration for the LCH4, and when the LCH4 generates uplink data transmission requirement, the ue may compare the priority of the LCH4 with the priority of the SR configuration 1, and determine whether to transmit a scheduling request using the SR configuration 1 according to the comparison result.
For example, when the priority of the LCH4 is higher than or equal to the priority of the SR configuration 1, the user equipment may determine to transmit the scheduling request using the SR configuration 1.
For another example, when the priority of the LCH4 is lower than the priority of the SR configuration 1, the user equipment may determine not to transmit the scheduling request, i.e., may not transmit the scheduling request through SR configuration 1.
Further, the priority of the SR configuration 1 may be obtained based on the indication information or other separate signaling (e.g., Radio Resource Control (RRC) signaling). For example, when determining to release the LCH1, the base station may set a priority for SR configuration 1 having a one-to-one mapping relationship with the LCH1, and notify the user equipment of releasing the LCH1 through the indication information, and notify the user equipment of the priority of SR configuration 1 through the indication information.
Further, the indication information may be RRC signaling.
By adopting the scheme of this embodiment, the ue can reasonably process the SR configuration having a mapping relationship (also referred to as an association relationship) with the LCH when the LCH is released, so that the resource of the SR configuration having a mapping relationship with the LCH can be effectively used by other LCHs or ues, thereby improving the resource utilization and avoiding resource waste.

As another variation, the processing module 22 may include: the third processing sub-module 223 is configured to suspend the SR configuration having a mapping relationship with the LCH, so that the SR configuration is in a known but unavailable state for the user equipment.

Further, the priority of the SR configuration may be obtained based on the indication information or other separate signaling.
Further, the determining sub-module 226 may include: a first determining unit 2261, when the priority of the other LCH is higher than or equal to the priority of the SR configuration, determining to transmit a scheduling request using the SR configuration; the second determining unit 2262 determines not to transmit the scheduling request when the priority of the other LCH is lower than the priority of the SR configuration.
