Detailed Description
As understood by those skilled in the art, as a matter of background, if the scheduling request response information fed back by the network indicates that the network cannot (or temporarily cannot) grant uplink resources for the user equipment, the user equipment may immediately attempt to request uplink resources from the network in other manners (e.g., send a scheduling request to the network through a random access procedure); or, the ue may also choose to send the scheduling request to the network again after the time period indicated by the scheduling request response information expires.
Based on such a scheme, for the network side, since the network does not know the processing logic of the user equipment after receiving the scheduling request response information, the network reserves PUCCH resources for the user equipment at least in the time period indicated by the scheduling request response information, so that the user equipment can be used when needed subsequently.
However, in practical applications, there is a high possibility that the ue may switch to send a scheduling request to the network in another manner within the time period indicated by the scheduling request response message, and the PUCCH resources reserved by the network for the ue are substantially in an idle state, which results in a serious waste of PUCCH resources. Especially for a scene that a large number of user equipment are connected to the same network, the existing network cannot efficiently allocate the PUCCH resources, and the effective utilization rate of the PUCCH resources on the network side is seriously influenced.
In order to solve the technical problem, for the user equipment side, receiving scheduling request response information; judging whether the network authorizes uplink resources according to the scheduling request response information; and when the judgment result shows that the network does not authorize the uplink resources, releasing the PUCCH resources. The technical solution of the embodiment of the present invention is that, when the network cannot grant uplink resources for the scheduling request of the ue, the ue can immediately release the PUCCH resources after receiving the scheduling request response information of the network, so as to avoid meaningless occupation of the PUCCH resources, thereby better improving the effective utilization of the PUCCH resources on the network side.
Further, for a network side, responding to a scheduling request of user equipment, and sending scheduling request response information to the user equipment, wherein the scheduling request response information is used for indicating whether uplink resources are authorized; and when the scheduling request response information indicates that the uplink resource is not authorized, releasing the PUCCH resource associated with the user equipment. The technical scheme of the embodiment of the invention can release the PUCCH resources allocated to the user equipment immediately when the uplink resource use requirement of the user equipment cannot be met, so that the limited PUCCH resources can be allocated to other user equipment with use requirement more reasonably, and the allocation logic of the PUCCH resources is optimized.
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 PUCCH resource release method according to a first embodiment of the present invention. Wherein, the PUCCH (Physical Uplink Control CHannel) resource may be used for a user equipment to send a scheduling request; the scheduling request may be used to indicate to the network that the user equipment has uplink data transmission requirements. Next, a specific operation flow of the PUCCH resource release method according to the embodiment of the present invention is specifically described from the user equipment side.
Specifically, in this embodiment, the PUCCH resource releasing method may include the following steps:
step S101, receiving scheduling request response information.
And step S102, judging whether the network authorizes the uplink resource according to the scheduling request response information.
And step S103, when the judgment result shows that the network does not authorize the uplink resource, releasing the PUCCH resource.
More specifically, the scheduling request response information may be issued by the network in response to a scheduling request transmitted by the user equipment.
Further, the scheduling request response information may include scheduling request acceptance information, scheduling request rejection information, and scheduling request temporary rejection information. The scheduling request acceptance information may be used to instruct the user equipment to accept the scheduling request by the network, and allocate uplink resources to the user equipment; the scheduling request rejection information may be used to indicate to the user equipment that the network has rejected its scheduling request, and the user equipment may attempt to send the scheduling request to the network again in other manners (e.g., through a random access procedure); the scheduling request temporary rejection information may be used to indicate that the network has temporarily rejected its scheduling request, and the network cannot allocate uplink resources to the user equipment temporarily, but the network indicates a time period for the user equipment through the scheduling request temporary rejection information, and the user equipment may send the scheduling request to the network again when the time period expires, so as to request that the network can allocate uplink resources to the network. The random access procedure may also be referred to as a random access procedure.
In a preferred embodiment, when the scheduling request response message is the scheduling request acceptance message, it may be determined that the network authorizes uplink resources; otherwise, that is, when the scheduling request response information is scheduling request rejection information or scheduling request temporary rejection information, it may be determined that the network does not authorize the uplink resource. Further, in addition to the scheduling request rejection information and the scheduling request temporary rejection information, the scheduling request response information may further include other information that may be used to indicate that the network cannot currently grant uplink resources for the user equipment, and when the user equipment receives and analyzes the scheduling request response information and finds that the network cannot currently grant uplink resources for the user equipment, the user equipment may perform step S103.
In a non-limiting embodiment, the scheduling request response information may further include indication information indicating that the user equipment releases the PUCCH resource, and the user equipment may perform a release operation of releasing the PUCCH resource according to the indication information when performing step S103.
Further, for scheduling request rejection information, the indication information indicated by the network may further include a reject and release instruction. For example, in response to the indication information, the user equipment may determine that the network has rejected the scheduling request of the user equipment and will release PUCCH resources allocated to the scheduling request.
Further, for scheduling request temporary rejection information, the indication information of the network indication may further include a reject-and-reserve instruction. For example, in response to the indication information, the ue may determine that the network cannot provide uplink grant for the scheduling request of the ue temporarily, but reserve a corresponding PUCCH resource for the ue so that the ue can use the PUCCH resource later.
In another non-limiting embodiment, the ue and the network may also agree in advance on the release logic of the PUCCH resource, and even if the scheduling request response information does not include the indication information, the ue may actively perform a release operation of releasing the PUCCH resource when receiving the scheduling request response information and determining that the network does not grant uplink resources.
For example, if the scheduling request response information (sent by the network in response to the scheduling request of the user equipment) indicates that the network does not grant the uplink grant to the user equipment, even if the received scheduling request response information does not include indication information indicating that the user equipment releases the PUCCH resource, the user equipment may automatically perform a release operation to release the PUCCH resource used for sending the scheduling request.
Further, the user equipment may be configured with multiple SR configurations (scheduling request configurations) at the same time. The SR configuration may correspond to a scheduling request, and the scheduling request corresponds to a PUCCH resource. Preferably, different traffic (traffic) types may correspond to different SR configurations; for different configurations (e.g., SR configurations) configured on the same ue, the different configurations may respectively correspond to Logical Channels (LCHs) that trigger the SRs.
In yet another non-limiting embodiment, the indication of the network may correspond to the scheduling request configuration (SRConfiguration, hereinafter abbreviated SR configuration). The step S103 may include: releasing the PUCCH resources associated with the scheduling request configuration corresponding to the indication of the network. For example, when one scheduling request sent by the user equipment receives scheduling request rejection information of the network, the user equipment may release only PUCCH resources associated with the SR configuration indicated by the scheduling request rejection information, instead of releasing all PUCCH resources associated with all SR configurations configured by the user equipment. Further, before the user equipment performs step S103, the user equipment may further perform the steps of: and sending feedback information to the network, wherein the feedback information is used for indicating the releasing operation of the PUCCH resources. For example, after determining that the network does not authorize the uplink resource, the ue may send feedback information to the network to notify the network that the ue will perform a release operation to release the PUCCH resource. Further, the user equipment may wait for a response of the network to its feedback information to determine whether to perform the release operation; alternatively, the user equipment may directly perform the release operation without waiting for a response from the network, and the feedback information only plays a role of notification.
Further, the releasing operation may include the steps of: sending indication information to an RRC to indicate the RRC to release PUCCH resources and Sounding Reference Symbols (SRS) of all serving cells; completing configured downlink tasks and/or uplink authorization; starting a random access process in a feature Cell (SpCell for short), and canceling all pending (pending) scheduling requests.
Preferably, the characteristic Cell may be a Primary Cell (PCell), for example, a Cell with a strongest signal in the serving Cell, so as to improve communication quality between the ue and the network. Further, for dual connectivity operation, the feature Cell may be a Primary Cell in a Primary Cell Group (MCG), or a Primary "Secondary Cell" (PSCell) in a Secondary Cell Group (SCG), where the Secondary Cell is a Cell in the Secondary Cell Group.
Preferably, the serving cell may include all cells in the network that the user equipment can access through an RRC connection.
By adopting the scheme of the first embodiment, when the network cannot grant the uplink resource for the scheduling request of the user equipment, the user equipment can immediately release the PUCCH resource after receiving the scheduling request response information of the network, so as to avoid meaningless occupation of the PUCCH resource, thereby better improving the effective utilization rate of the PUCCH resource on the network side.
Fig. 2 is a schematic structural diagram of a PUCCH resource releasing apparatus according to a second embodiment of the present invention. Those skilled in the art understand that the PUCCH resource releasing apparatus 2 in this embodiment is used to implement the method technical solution in the embodiment shown in fig. 1.
More specifically, in this embodiment, the PUCCH resource releasing apparatus 2 may include a receiving module 21, configured to receive scheduling request response information; a judging module 22, configured to judge whether the network authorizes the uplink resource according to the scheduling request response information; and the releasing module 24 is configured to release the PUCCH resource when the determination result indicates that the network does not authorize the uplink resource.
Further, the determining module 22 may include a first determining sub-module 221, which determines that the network authorizes the uplink resource when the scheduling request response information is scheduling request acceptance information. Alternatively, the determining module 22 may further include a second determining sub-module 222, configured to determine that the network does not authorize the uplink resource when the scheduling request response information is not the scheduling request acceptance information.
Preferably, the operation of releasing the PUCCH resources is performed in response to an indication of the network; alternatively, the operation of releasing the PUCCH resources is performed actively.
Preferably, the indication of the network is received from the scheduling request response information.
Further, when there are a plurality of scheduling request configurations, the indication of the network corresponds to the scheduling request configuration; the release module 24 includes: a releasing submodule 241, configured to release the PUCCH resource associated with the scheduling request configuration corresponding to the indication of the network.
Further, the PUCCH resource releasing apparatus 2 may further include a sending module 23, configured to send feedback information to the network before releasing the PUCCH resource, where the feedback information is used to indicate a releasing operation of the PUCCH resource.
Further, the releasing module 24 may include a sending sub-module 242, configured to send indication information to the RRC to indicate the RRC to release PUCCH resources and sounding reference symbols of all serving cells; a first processing sub-module 243, configured to complete configured downlink tasks and/or uplink grants; a second processing sub-module 244 is used for starting the random access procedure in the characteristic cell and canceling all the pending scheduling requests.
For more details of the operation principle and the operation mode of the PUCCH resource releasing apparatus 2, reference may be made to the description in fig. 1, which is not repeated here.
Fig. 3 is a flowchart of a PUCCH resource release method according to a third embodiment of the present invention. The present embodiment specifically describes a specific operation flow of the PUCCH resource release method according to the present embodiment from the network side.
Specifically, in this embodiment, the PUCCH resource releasing method may include the following steps:
step S201, responding to a scheduling request of a user equipment, and sending scheduling request response information to the user equipment, where the scheduling request response information is used to indicate whether to grant uplink resources.
Step S202, when the scheduling request response information indicates that the uplink resource is not authorized, releasing the PUCCH resource associated with the user equipment.
More specifically, the detailed description about the scheduling request response information may refer to the related description in fig. 1, which is not repeated herein.
In one non-limiting embodiment, when the network can grant uplink resources for the ue, for example, the network currently has idle uplink resources that can be granted to the ue for use, the network may send scheduling request acceptance information to the ue; otherwise, that is, the network cannot grant uplink resources for the user equipment, the network may send scheduling request rejection information or scheduling request temporary rejection information to the user equipment.
In a preferred embodiment, after the scheduling request response information is sent to the ue and the scheduling request response information is used to indicate that the network does not authorize the ue to uplink resources, the network may actively perform a release operation for releasing PUCCH resources associated with the ue. Wherein the PUCCH resources associated with the user equipment can be resources allocated by the network to the user equipment for transmitting the scheduling request; releasing the PUCCH resource associated with the user equipment may include switching the resource to an idle state, which may be further allocated to other user equipment in the network for use. For example, the network may further instruct the ue through the scheduling request response information, and after receiving the scheduling request response information, the network releases the PUCCH resource on the ue side, and at the same time, the network also releases the PUCCH resource allocated to the ue on the network side.
Or, as a variation, before releasing the PUCCH resource associated with the user equipment, the network may further perform the steps of: and receiving feedback information of the user equipment, wherein the feedback information is used for indicating the user equipment to release the PUCCH resources. Further, the network may perform the release operation according to content indicated by the feedback information, where the feedback information may be sent by the ue in response to the scheduling request response information. For example, the network may perform the release operation when the feedback information of the user equipment indicates that the user equipment is to release the PUCCH resource.
Thus, with the scheme of the third embodiment, after sending the scheduling request response information indicating the unauthorized uplink resource to the user equipment, the network may immediately release the PUCCH resource allocated to the user equipment, so as to be used by other user equipment having a requirement for accessing the uplink resource, and optimize the allocation logic of the PUCCH resource.

Further, when the scheduling request response information is scheduling request acceptance information, the scheduling request response information is used for indicating to authorize the uplink resource; otherwise, the method is used for indicating that the uplink resource is not authorized.
Further, the operation of releasing PUCCH resources associated with the user equipment is performed in response to feedback information of the user equipment; alternatively, the operation of releasing PUCCH resources associated with the user equipment is performed actively.
Further, the PUCCH resource releasing apparatus 4 may further include a receiving module 42, configured to receive feedback information of the user equipment before releasing the PUCCH resource associated with the user equipment, where the feedback information is used to indicate a releasing operation of the PUCCH resource by the user equipment.

Specifically, in this application scenario, the user equipment 1 may perform operation s1 to send a scheduling request to the network 2, where the scheduling request may be used to request the network 2 to grant uplink resources.
Further, after receiving the scheduling request, in response to the scheduling request, the network 2 may perform operation s2 to determine whether to grant uplink resources to the user equipment 1.
Further, after determining that the uplink resource cannot be granted to the user equipment 1, the network 2 may perform operation s3 to send scheduling request response information to the user equipment 1, where the scheduling request response information may be used to indicate that the network 2 does not grant the uplink resource.
Further, the network 2 may also perform operation s4 to release PUCCH resources associated with the user equipment 1.
