Embodiment Construction

[0057] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0058] In the LTE system, data transmission needs to occupy certain resources in the time-frequency domain. Occupying resources in the time domain refers to which time or subframe to send; occupying resources in the frequency domain refers to which subcarrier to send. Generally speaking, a physical layer data channel for sending data such as PDSCH / PUSCH is composed of a corresponding physical layer control channel such as a physical downlink control channel (Physic...

Abstract

The embodiment of the invention discloses a method of data transmission. The method comprises: determining starting positions, including a starting sub frame position and / starting narrow-band position, of control channel transmission; according to the starting positions of the control channel transmission, one or more of a time interval of the control channel transmission, a sending period of the control channel, a hybrid automatic repeat request process identifier, and the number of hybrid automatic repeat request processes, and a preset rule, a starting position of a data channel of control channel scheduling is determined; and on the basis of the determined starting position of the data channel, data are transmitted. In addition, the embodiment of the invention also discloses a base station. Therefore, when the terminal does not receive previous indication information, normal operation of follow-up data transmission can be guaranteed.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a data transmission method and a base station. Background technique [0002] The Internet of Things refers to a network that obtains information in the physical world by deploying various devices with certain perception, calculation, execution and communication capabilities, and realizes information transmission, collaboration and processing through the network, thereby realizing the interconnection of people and things, and things and things. . In short, the Internet of Things is to realize the interconnection between people and things, things and things (Machine to Machine, M2M). In order to provide a long-term evolution (Long Term Evolution, LTE) terminals to replace GSM / GPRS terminals used in IoT applications, so that LTE networks can be used to replace GSM / GPRS networks in M2M applications. The 3rd Generation Partnership Project (3rd Generation Partnershi...
