[0002] In the new radio (NR) system, the scheduling request (SR) configuration can correspond to a set of physical uplink control channel (PUCCH) resources. Different PUCCH resource sets correspond to different objects, including bandwidth part (BWP) and cell. For example, if n BWPs are configured on a cell (or carrier), the number of PUCCH resource sets included in the SR configuration can be the product of n and the number of cells supporting PUCCH.

[0029] Figure 1 FIG. 1 is a schematic flow chart of a method 100 for transmitting an SR according to an embodiment of the present application, and the method 100 may be executed by a terminal device. Figure 1 As shown, the method 100 includes: S110, determining that there are multiple PUCCH resources at the target time, the multiple PUCCH resources correspond to different SR configurations, and the different SR configurations correspond to different logical channels.

[0030] The SR in the embodiment of the present application can be used to request uplink resources from the network device. For example, when there is uplink data to be sent on the terminal device side, the SR can be used to request the network device to allocate uplink resources, so that the network device can allocate uplink resources to the terminal device according to the SR.

[0031] The SR in the embodiment of the present application has a corresponding SR configuration. For any SR configuration, the SR configuration can maintain an SR counter (Counter) and a timer (Timer). The function of the SR Counter is to record the number of SR transmissions corresponding to the SR configuration; and the function of the SR Timer is to prevent excessive SR retransmissions. For example, corresponding to the SR configuration, an SR has been transmitted within the timer action time. If the SR transmission time of the next cycle also arrives, the transmission will be prohibited by the Timer.

[0032] In an embodiment of the present application, at any moment, there may be one or more SRs in a pending state in a media access control (MAC) entity of the terminal device. The pending state means that the transmission of the SR is triggered according to the triggering condition of a regular buffer status report (BSR), but the SR transmission time has not yet arrived, and the MAC entity places the triggered SR in a pending state.

[0033] It should be understood that at the target moment, there are multiple PUCCH resources available in the MAC entity of the terminal device, and the multiple PUCCH resources correspond to multiple SRs, that is, each PUCCH resource in the multiple PUCCH resources corresponds to an SR, wherein at least two PUCCH resources in the multiple PUCCHs correspond to different SRs, and there may also be two or more PUCCH resources corresponding to the same SR; the target moment can be any moment. The multiple SRs have different SR configurations, that is, the multiple PUCCH resources correspond to different SR configurations, and the different SR configurations have a mapping relationship with different logical channels. Among them, multiple SRs have different SR configurations, including: each SR in the SR corresponds to an SR configuration, there may be two or more SRs in the multiple SRs corresponding to the same SR configuration, and there are also at least two SRs corresponding to different SR configurations, and correspondingly, there may be multiple PUCCH resources in the multiple PUCCH resources corresponding to the same SR configuration, and there are also at least two PUCCH resources corresponding to different SR configurations.

[0034] The multiple PUCCH resources in the embodiment of the present application may be in different configured bandwidth parts, or in different cells, or in different bandwidth parts and cells. The embodiment of the present application is not limited to this.

[0035] It should be understood that multiple PUCCH resources correspond to different SR configurations, each of which includes one or more PUCCH resource sets, and each PUCCH resource set refers to a PUCCH resource with a certain configuration period, including time domain and frequency domain. In addition, any PUCCH resource set can be located on a certain configured BWP.

[0036] The SR configuration in the embodiment of the present application has a mapping relationship with the logical channel. Each logical channel is mapped to at most one SR configuration, and each SR configuration can be mapped to one or more logical channels.

[0037] The method 100 further includes: S120, determining a target PUCCH resource from the multiple PUCCH resources according to the priorities of the different logical channels.

[0038] In the present application, for different logical channels mapped with different SR configurations corresponding to multiple PUCCH resources, the priority of each logical channel in the different logical channels can be determined, and based on the priority of each logical channel, the target logical channel can be determined in the multiple different logical channels, the SR configuration corresponding to the target logical channel can be determined as the target SR configuration, and the PUCCH resources corresponding to the target SR configuration in multiple PUCCH resources can be determined as the target PUCCH resources.

[0039] In one embodiment, the terminal device may determine the logical channel with the highest priority among the different logical channels as the target logical channel. Specifically, when there is a logical channel with the highest priority among the different logical channels, the logical channel with the highest priority is the target logical channel; when there are at least two logical channels with the highest and equal priorities among the different logical channels, the at least two logical channels may be determined as the target logical channels; or, a logical channel may be randomly selected from the at least two logical channels or selected by other rules as the target logical channel; or, at least one SR configuration corresponding to the at least two logical channels is determined, and at least one PUCCH resource corresponding to the at least one SR configuration is determined. If the at least one PUCCH resource is a plurality of different PUCCH resources, the target PUCCH resource is selected from the different PUCCH resources by random selection or according to preset rules. The embodiments of the present application are not limited to this.

[0040] In one embodiment, the terminal device can receive an RRC message sent by a network device, where the RRC message is used to indicate the priority of a logical channel of the terminal device. The terminal device can then determine the priority of different logical channels mapped to different SR configurations corresponding to multiple PUCCH resources based on the RRC message.

[0041] The method 100 further includes: S130, sending an SR to a network device using the target PUCCH resource at the target time.

[0042] Specifically, the terminal device determines the SR corresponding to the target PUCCH resource, and uses the target PUCCH resource to send the corresponding SR to the network device at the target moment. The SR has a target SR configuration corresponding to the target PUCCH resource, and the target SR configuration corresponds to the target logical channel.

[0043] In one embodiment, the target PUCCH resource determined by the terminal device may include only one PUCCH resource or may include at least two PUCCH resources. If the target PUCCH resource is one PUCCH resource, the terminal device uses the one target PUCCH resource to send the corresponding SR to the network device at the target time; if the target PUCCH resource includes at least two PUCCH resources, the terminal device may use the at least two PUCCH resources to send the same SR, or the terminal device determines one PUCCH resource from the at least two PUCCH resources to send the SR.

[0044] Specifically, for the case where the target PUCCH resources include at least two PUCCH resources, the terminal device can use the at least two PUCCH resources to send the same SR; or, randomly select or select one or more PUCCH resources according to a certain rule from the at least two PUCCH resources to send the SR. The embodiments of the present application are not limited to this.

[0045] In one embodiment, in the case where the PUCCH resource includes at least two PUCCH resources, the terminal device may select one or more resources from the at least two PUCCH resources to send an SR by means of Listen Before Talk (LBT). Specifically, the terminal device performs LBT on the PUCCH resource in an unlicensed frequency band, and selects an unoccupied PUCCH resource from at least two PUCCH resources included in the target PUCCH resource according to the LBT result, and uses the one PUCCH resource to send an SR; or selects multiple unoccupied PUCCH resources from at least two PUCCH resources included in the target PUCCH resource according to the LBT result to send the same SR, and the embodiments of the present application are not limited to this.

[0046] Therefore, in the method of transmitting SR in an embodiment of the present application, when there are multiple PUCCH resources available at any time, and the multiple PUCCH resources correspond to different SR configurations, and the different SR configurations correspond to different logical channels, the terminal device can select the SR configuration corresponding to the logical channel with a higher priority according to the priority of the different logical channels, and use the PUCCH resource corresponding to the SR configuration among the multiple PUCCH resources to send SR to the network device, so as to avoid conflicts among the multiple PUCCH resources and improve transmission efficiency.

[0047] It should be understood that in the various embodiments of the present application, the size of the serial numbers of the above-mentioned processes does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0048] In addition, the term "and / or" in this article is only a description of the association relationship between the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.
