Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the following will clearly and completely describe the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention. Apparently, the described embodiments are some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention belong to the protection scope of the present invention.

In LTE, SR configuration is configured through RRC (Radio Resource Control, radio resource control). The configuration information of SR in 3GPP (Third Generation Partnership Projects) agreement 36.331 is as follows:

The eNodeB (base station) can allocate a dedicated SR resource (PUCCH format 1) to each UE for sending SR. The SR resource is periodic and occurs every n subframes. The period of SR is configured through the sr-ConfigIndex field of IE:SchedulingRequestConfig. The correspondence between sr-ConfigIndex corresponding to SRperiodicity (SR period) and SR subframe offset (SR subframe offset) is as follows (see 3GPP protocol 36.213 for details):

Table 1 UE-specific SR resource period and subframe interval configuration

In the SR procedure (SR process), when an SR is triggered (triggered), it is a pending SR. When the base station allocates uplink resources and the UE reports a BSR (buffer state report, buffer state report), all pendingSRs are canceled and the sr-prohibittimer (timer) is stopped at the same time. sr-prohibittimer is used to characterize the interval of pending SR. According to 3GPP protocol 36.331, the optional value is 0-7. That is, corresponding to an SR procedure, the SR resource is idle during the time when the SR disables the trigger. Similarly, in 5GNR, SR resources are also idle during the time when the SR disables the trigger. Therefore, during this period, the idle SR resources can be used by other LCHs.

Please refer to FIG. 1. FIG. 1 is a schematic flowchart of a method for configuring SR resources provided by Embodiment 1 of the present invention. The method is applied to a network side device and includes the following steps:

Step 11: Send configuration information to the terminal, the configuration information including: the common PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel) resources of the LCH (logical channel, logical channel) of the terminal for sending SR and/or Or a dedicated PUCCH resource, wherein the common PUCCH resource is a PUCCH resource that the LCH can share with other LCHs of the terminal, and the dedicated PUCCH resource is a PUCCH resource dedicated to the LCH.

The embodiment of the present invention is mainly applicable to 5G NR. The network side device configures resources for sending SR for each LCH of the terminal separately, that is, SR configuration in NR is a configuration of LCH granularity (level). Wherein, when configuring SR resources (PUCCH resources) for the LCH of the terminal, SR resources that can be shared with other LCHs can be configured for the LCH, thereby solving the problem that some LCHs do not have corresponding SR resources due to insufficient SR resources.

In the 3GPP protocol, the SR configuration information about NR is:

Wherein, sr-PUCCH-ResourceIndex-Common and sr-PUCCH-ResourceIndex-Specific/Dedicated correspond to sr-PUCCH-ResourceIndex in LTE.

The following example illustrates the above SR resource configuration method.

In an optional specific implementation manner, for the terminal, the number of common PUCCH resources is zero, one or more. In the embodiment of the present invention, a dedicated dedicated SR resource (sr-PUCCH-ResourceIndex-Specific/Dedicated) can be configured for each LCH of a certain terminal, and some LCHs in the terminal can also be configured to be shared with other LCHs. A common SR resource (sr-PUCCH-ResourceIndex-Common), where there may be one or more common SR resources, and when there are multiple common SR resources, some LCHs in the terminal share one of the common SR resources resources, and another part of LCHs shares other SR resources. In addition, the common PUCCH resources can only be shared by the LCH of the terminal, and cannot be shared with LCHs of other terminals.

For each LCH of the terminal, there are zero or one dedicated PUCCH resources.

For each of the LCHs of the terminal, there are zero or one common PUCCH resources.

Each LCH corresponds to at least one of a dedicated PUCCH resource and a common PUCCH resource, and some LCHs may simultaneously correspond to a dedicated PUCCH resource and a common PUCCH resource.

Please refer to FIG. 2. FIG. 2 is a schematic flowchart of an LCH-based resource request method provided in Embodiment 2 of the present invention. The method is applied to a terminal and includes the following steps:

In the embodiment of the present invention, each LCH of the terminal is configured with at least one of common PUCCH resources and dedicated PUCCH resources, that is, when the PUCCH resources used for sending SRs are insufficient, part of the LCHs of the terminal can communicate with other The LCHs share common PUCCH resources, so that when there is data to be uploaded by these LCHs, they can use the common PUCCH resources to send an SR to the network side device.

Among them, different SR resources (PUCCH resources) have different positions, so the network side device can judge which LCH of which terminal needs to upload data according to the position of the received SR PUCCH resource, and then according to the relevant information of the LCH (such as priority , QoS (Quality of Service flow), etc.) to schedule uplink resources.

The following example illustrates the resource request method based on the LCH.

In one of the optional embodiments, the terminal corresponds to zero or one or more common PUCCH resources.

Optionally, the LCH corresponds to zero or one dedicated PUCCH resource.

Optionally, the LCH corresponds to zero or one common PUCCH resource.

sr-prohibittimer (SR timer) is an integer multiple of sr-period (SR period). That is, corresponding to an SRprocedure, the SR resources are idle during the time when the SR disables the trigger. Therefore, for a common PUCCH resource, after a LCH uses the common PUCCH to send SR, the LCH enters the sr-prohibittimer timing time and is prohibited from triggering SR, then other LCHs can use the common PUCCH during this period Send an SR.

In this embodiment of the present invention, the terminal uses the SR resource (PUCCH resource) configured by the network side device in the first embodiment above to send an SR to the network side device. For related content, please refer to the first embodiment above.
