Problems solved by technology

[0016] The 5G system supports the coexistence of multiple numerology and / or TTI lengths, and the numerology and / or TTI length that can be used by a bearer / logical channel of the terminal is configured for the terminal by the network side. In this case, a certain bearer / logical channel of the terminal needs to be resolved. There is a demand for uplink data transmission, but how to perform uplink data transmission when the terminal has no available uplink resources on the physical resources corresponding to the numerology and / or TTI length it can use

Embodiment 1

[0086] see figure 1 , the figure shows a flow of an uplink data transmission method, and the specific steps are as follows:

[0087] Step 101, if a bearer and / or logical channel of the terminal has an uplink data transmission requirement, and the terminal has no available uplink resources on physical resources corresponding to the available numerology and / or TTI length of the bearer and / or logical channel , the SR and / or BSR process is triggered.

[0088] The terminal has no available uplink resources on physical resources corresponding to the bearer and / or logical channel available numerology and / or TTI length, including:

[0089] The terminal has no available uplink resources on the physical resources corresponding to the available numerology of the bearer and / or logical channel;

[0090] The terminal has no available uplink resources on the physical resources corresponding to the available TTI length of the bearer and / or logical channel;

[0091] The terminal has no avai...

Embodiment 2

[0154] Embodiment 2: SR and / or BSR can only be transmitted on physical resources corresponding to one or some specific numerology and / or TTI lengths corresponding to the bearer / logical channel

[0155] see figure 2 , the figure shows a flow of SR / BSR triggering method, the specific steps are as follows:

[0156] Step 201, a certain bearer / logical channel of the terminal has an uplink data transmission requirement;

[0157] When a certain bearer / logical channel of the terminal has an uplink data transmission requirement but the terminal does not have uplink resources on the physical resources corresponding to the available numerology and / or TTI length of the bearer / logical channel, the SR and / or BSR process is triggered.

[0158] Step 202, the terminal selects SR and / or BSR transmission resources.

[0159] The SR and / or BSR triggered by a certain bearer / logical channel of the terminal can only be transmitted on the physical resources corresponding to one or some specific num...

Embodiment 3

[0165] Embodiment 3: Transmission on physical resources corresponding to any numerology and / or TTI length of SR and / or BSR

[0166] see image 3 , the figure shows a flow of SR / BSR triggering method, the specific steps are as follows:

[0167] Step 301: A certain bearer / logical channel of the terminal has an uplink data transmission requirement;

[0168] When a certain bearer / logical channel of the terminal has an uplink data transmission requirement but the terminal does not have uplink resources on the physical resources corresponding to the available numerology and / or TTI length of the bearer / logical channel, the SR and / or BSR process is triggered.

[0169] Step 302: The terminal selects SR and / or BSR transmission resources.

[0170] Whether the SR and / or BSR triggered by a certain bearer / logical channel of the terminal can only be transmitted on the physical resource corresponding to one or some specific numerology and / or TTI length corresponding to the bearer / logical ch...

Abstract

An embodiment of the present invention provides an SR / BSR triggering method and device, the method including: if a bearer and / or logical channel of a terminal has an uplink data transmission requirement, and the terminal is available on the bearer and / or logical channel When there is no uplink resource available on the physical resource corresponding to the numerology and / or TTI length, the SR and / or BSR process is triggered. Through the embodiments of the present invention, it can be ensured that the terminal can normally perform uplink data transmission under the coexistence of multiple numerology and / or TTI lengths.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to an SR (Scheduling Request, scheduling request) / BSR (Buffer Status Report, buffer status report) triggering method and device. Background technique [0002] 1) Introduction of SR and / or BSR mechanism [0003] The LTE (Long Term Evolution, long-term evolution) / LTE-A (abbreviation for LTE-Advanced, which is the subsequent evolution of LTE technology) system is a communication system based on scheduling, that is, if there is data to be sent in the transmission buffer of the UE, then The UE needs to first send a BSR to the base station, and inform the base station of the data information to be sent in the current sending buffer of the UE (User Equipment, user equipment). After receiving the BSR sent by the UE, the base station allocates corresponding uplink shared channel (UL-SCH, Uplink Shared Channel) resources for the UE according to the amount of data to be sen...
