Abstract

The embodiment of the invention discloses an uplink transmission method and a base station. The method comprises the steps of determining a time length of a single transmission time interval t and a time delay correction value k corresponding to a business type by the base station according to the transmitted business type; transmitting an uplink authorization signaling to a terminal, and indicating uplink transmission information of uplink data in the uplink authorization signaling, wherein the uplink transmission information comprises the time of transmitting the uplink data for the first time and the number of times of transmitting the uplink data, or the uplink transmission information comprises the time of transmitting the uplink data for the first time, the number of times of transmitting the uplink data, and a time interval of transmitting the uplink data every two times; notifying the terminal of time length information of t, information of k and the uplink transmission information; and receiving the uplink data transmitted by the terminal according to the time length information of t, the information of k and the uplink transmission information, and finishing uplink transmission. By adopting the uplink transmission method and the base station provided by the invention, the base station is facilitated to adjust an uplink scheduling time delay according to the business type, and the diversified demands of 5G business in the future can be satisfied.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for uplink transmission and a base station. Background technique [0002] With the rapid increase of users' communication demands, the traffic volume of communication has shown explosive growth. The resource scheduling granularity and processing delay of Long Term Evolution (LTE) and Long Term Evolution-Advanced (LTE-A) have been improved. Can not fully meet the needs of users. Specifically, in the existing 4G and 4.5G mobile communication technologies, it is all performed based on the unit time length in the LTE and LTE-A radio access technologies. The size of its unit time length is usually fixed. For example, in LTE technology, the unit time length is usually a subframe, and the time length of a subframe is 1 millisecond. Therefore, in LTE technology, a transmission time interval (Transmission Time Interval , TTI) is the duration of a unit time length...
