Embodiment 1

[0135]This embodiment is applied to an SR triggering scenario in an uplink scheduling process, and relates to how to request uplink resources from a network device to meet the QoS requirements of logical channel data.

[0136] figure 2 It is a schematic diagram of an existing scenario where SR cannot be triggered. Assume that the terminal device is configured with two logical channels, namely logical channel 1 (LCH1) and logical channel 2 (LCH2). in,

[0137] 1) The value of the available / mappable transmission parameter set of LCH1 configured by the network device for the terminal device is the first value set, and the mapped / associated SR configuration configured by the network device for LCH1 is the first SR configuration.

[0138] 2) The value of the available / mappable transmission parameter set of LCH2 configured by the network device for the terminal device is the second value set, and the mapped / associated SR configuration configured by the network device for LCH2 is ...

Embodiment 2

[0203] This embodiment is applied to the SR transmission scenario in the uplink scheduling process. image 3 Based on the first embodiment shown, it involves how to transmit the SR after the SR has been triggered.

[0204] Figure 5 It is a flow chart of the scheduling request processing method provided in Embodiment 2 of the present application. Such as Figure 5 As shown, after S102, the method for processing a scheduling request provided in this embodiment may further include:

[0205] S201. The terminal device determines the first logical channel or the SR configuration corresponding to the triggered SR.

[0206] Wherein, the SR configuration may include at least one of the following parameters: an SR configuration identifier, an SR prohibition timer, a maximum number of SR transmissions, and a parameter for determining the location of a physical resource used to transmit an SR.

[0207] The concept of the SR configuration can have the following situations:

Embodiment 3

[0251] This embodiment is applied to the SR canceling scenario in the uplink scheduling process, and involves how to cancel the SR after the SR has been triggered on the basis of the first or second embodiment above.

[0252] Figure 6 It is a flow chart of the scheduling request processing method provided in Embodiment 3 of the present application. Such as Figure 6 As shown, after S102, the method for processing a scheduling request provided in this embodiment may further include:

[0253] S301. If the terminal device has uplink resources available for transmitting data of the first logical channel, the terminal device cancels the SR.

[0254] Specifically, after the terminal device triggers the SR associated with the first logical channel, as long as the terminal device has uplink resources available for transmitting data of the first logical channel, the SR can be canceled. In this way, resources are saved, terminal power consumption is saved, and repeated scheduling an...

Abstract

The embodiment of the invention provides a scheduling request processing method and terminal equipment. The scheduling request processing method comprises the following steps: the terminal equipment determines whether a conventional BSR associated with a first logic channel is triggered and is not cancelled yet; if the conventional BSR associated with the first logical channel is triggered and notcanceled yet, the terminal equipment does not have uplink resources which can be used for transmitting the data of the first logical channel, and a first timer of the terminal equipment does not run,the terminal equipment triggers the SR; wherein the first timer is used for delaying the transmission of the SR. According to the scheduling request processing method provided by the embodiment of the invention, when the terminal equipment does not have the uplink resource which can be used for transmitting the data of the logic channel associated with the BSR, the uplink resource scheduling is realized by triggering the SR, and the QoS requirement of the data borne by the logic channel is met.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to a method for processing a scheduling request and a terminal device. Background technique [0002] In the future 5G communication system, the terminal device can report the terminal device to the network device by filling the buffer status report (Buffer StatusReport, BSR) into the media access control (Media Access Control, MAC) protocol data unit (ProtocolData Unit, PDU). amount of data to be sent. Correspondingly, the network device may send an uplink grant (Uplink grant, UL grant) to the terminal device based on the BSR sent by the terminal device, so as to allocate uplink resources for the terminal device. [0003] Wherein, data of services with different Quality of Service (Quality of Service, QoS) requirements are transmitted through different Logical Channels (Logical Channel, LCH). In the future 5G communication system, differen...
