Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] The present invention provides a data processing method and a terminal for the problem that there is no agreement on how to rationally use grant-free resources for data transmission by terminals in 5G communication, and the reliability of network communication cannot be guaranteed.

[0034] Such as Figure 4 As shown, an embodiment of the present invention provides a data processing method, including:

[0035] Step 401, acquiring at least one Hybrid Automatic Repeat Request (HARQ) process allocated for scheduling-free resources;

[0036] It should be noted that this data processing method is applied to the terminal side. In this embodiment, the network side will configure at least one HARQ process for the terminal in advance for the scheduli...

Abstract

The invention provides a data processing method and a terminal, and relates to the technical field of communication. The data processing method comprises the steps that at least one hybrid automatic repeat request (HARQ) process allocated to an unscheduled resource is acquired; and when data transmission is conducted by means of the first HARQ process in the at least one HARQ process, data in a cache of the first HARQ process is processed, wherein the data is processed through at least one of the modes of wiping the data in the cache, retaining the data in the cache and updating the data in the cache. According to the scheme, by processing the data in the cache of the HARQ process adopted by the unscheduled resource and then sending the data to a base station by means of the HARQ process,the 5G data transmission mode is improved, therefore, the reliability and the validity of data transmission are guaranteed, and the reliability of network communication is guaranteed.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data processing method and a terminal. Background technique [0002] At present, in a Long Term Evolution (LTE for short) system, when a terminal (User Equipment, UE for short) sends uplink data, it usually only sends it on the uplink resources authorized by the base station for real-time scheduling based on the uplink scheduling authorization method of the base station. upstream data. That is to say, before sending uplink data, the current UE needs to receive an uplink grant (UL-grant) message sent by the base station, and send uplink data on the uplink resource indicated by the uplink grant message. In this way, since the UE needs to receive the uplink authorization message sent by the base station before sending uplink data, it will cause a large data delay and signaling overhead. [0003] In order to reduce the delay and data overhead, for the fifth generat...
