Abstract

The invention discloses a method used in uplink data transmission, a terminal device and a network device. The method comprises the following steps: a network device generates configuration information for a CTU (Contention Transmission Unit) of an uplink first sub-band, wherein the first sub-band is one sub-band of multiple uplink sub-bands, the multiple uplink sub-bands are respectively provided with a special configuration, and the CTU is a resource unit used for carrying out grant free transmission on the first sub-band; and the network device sends the configuration information of the CTU. According to the method used in the uplink data transmission, the terminal device and the network device provided by the embodiment of the invention, the terminal device can obtain the information of the CTU quickly and effectively, thereby carrying out the grant free transmission; and the efficiency of a system to transmit data can be improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for uplink data transmission, a network device and a terminal device in the communication field. Background technique [0002] With the continuous evolution of wireless cellular networks, the next-generation mobile communication system will not only support traditional communication, but also machine-to-machine (M2M) communication, or Machine Type Communication (Machine Type Communication, referred to as "MTC") communication. According to predictions, by 2020, the number of MTC devices connected to the network will reach 50 to 100 billion, which will far exceed the current number of connections. For M2M services, due to the wide variety of service types, there are great differences in network requirements. Generally speaking, there will be the following requirements: (I) reliable transmission, but not sensitive to delay; (II) low delay, highly reliable transmission. ...
