Problems solved by technology

[0003] An embodiment of the present invention provides an uplink data sending method, a receiving method, a user terminal, and a network-side device, so as to solve the problem that the user terminal needs to receive the uplink authorization scheduling message sent by the network-side device before the user terminal can receive the uplink authorization scheduling message. Sending uplink data on uplink resources causes large data delay and signaling overhead

[0042] see figure 1 , figure 1 is a flowchart of a method for sending uplink data provided by an embodiment of the present invention, the method is applied to a user terminal, such as figure 1 shown, including the following steps:

[0043] Step 101: Receive configuration signaling sent by a network side device, where the configuration signaling is used to configure grant-free uplink resources for the user terminal.

[0044] Wherein, the above-mentioned configuration signaling may be sent through a dedicated channel or a broadcast message, and of course, it does not rule out sending it in an interactive manner between other user terminals and the network side equipment. In addition, the foregoing configuration signaling may be radio resource control (Radio Resource Control, RRC) signaling or high-level signaling, which is not limited in this embodiment of the present invention.

[0045] The aforementioned scheduling-free uplink resource may be that when the user terminal sen...

[0052] see figure 2 , figure 2 is a flowchart of a method for sending uplink data provided by an embodiment of the present invention, the method is applied to a user terminal, such as figure 2 shown, including the following steps:

[0053] Step 201: When the user terminal establishes an RRC connection with the network-side device, receive configuration signaling sent by the network-side device, where the configuration signaling is used to configure scheduling-free uplink resources for the user terminal .

[0054] Wherein, step 201 may implement receiving configuration signaling sent by the network side device when the user terminal establishes an RRC connection with the network side device, for example: configuring scheduling-free uplink resources for the user terminal through RRC signaling.

[0055] Since it can be realized that when the RRC connection is established, that is, during the RRC connection process between the user terminal and the network-side device, the u...

[0123] see image 3 , image 3 is a flowchart of a method for receiving uplink data provided by an embodiment of the present invention, and the method is applied to a network side device, such as image 3 shown, including the following steps:

[0124] Step 301. Send configuration signaling to the user terminal, where the configuration signaling is used to configure scheduling-free uplink resources for the user terminal.

[0125] For the above-mentioned configuration of signaling and scheduling-free uplink resources, reference may be made to the corresponding descriptions of the first to second embodiments, which will not be repeated here, and the same beneficial effect can be achieved.

[0126] Step 302: On the uplink resource, receive uplink data sent by the user terminal.

[0127]Wherein, receiving the uplink data here includes the situation of successful reception, reception failure, or abnormal reception. For the above uplink data, reference may be made to the correspo...

Abstract

The embodiment of the invention provides an uplink data sending method, an uplink data receiving method, a user terminal, and a network side device. The method comprises the following steps: receivingconfiguration signaling sent by the network side device, wherein the configuration signaling is used for configuring an unscheduled uplink resource to the user terminal; and sending uplink data to the network side device on the uplink resource. Therefore, when the user terminal sends the uplink data, the uplink scheduling of the network side device is not needed, therefore, by adoption of the uplink data sending method, the uplink data receiving method, the user terminal, and the network side device provided by the embodiment of the invention, the data delay and the signaling overhead can bereduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to an uplink data sending method, a receiving method, a user terminal, and a network side device. Background technique [0002] At present, in a Long Term Evolution (LTE for short) system, when a user terminal (User Equipment, UE for short) sends uplink data, usually only based on the uplink scheduling authorization method of the network side equipment, the network side equipment schedules the authorization in real time. Send uplink data on the uplink resource. That is to say, before sending uplink data, the current UE needs to receive the uplink grant scheduling message sent by the network side device, and send uplink data on the uplink resource indicated by the uplink grant scheduling message. In this way, since the user terminal needs to receive the uplink grant scheduling message sent by the network side device before it can send uplink dat...
