This patent document is a continuation of and claims the benefit of priority to International Patent Application No. PCT/CN2018/115101, filed on Nov. 12, 2018, which claims the benefit of priority to Chinese Patent Application No. 201711107748.1, filed on Nov. 10, 2017. The entire contents of the before-mentioned patent applications are incorporated by reference as part of the disclosure of this application.
The present disclosure relates to, but is not limited to, the field of wireless communication technologies, and in particular, to a method for determining an uplink control channel scheduling unit, a base station and a user equipment.
5G NR (New Radio) is an ongoing 3GPP (3rd generation partnership project) study item, which determines a new wireless air interface standard based on orthogonal frequency division multiplexing (OFDM) and will become the foundation for a next generation mobile network.
In an NR system, a scheduling unit (for example, a slot (slot), which will be described with a slot as an example below) has various structures, which may be flexibly configured by a base station. In some cases, a slot may include one or more of the following parts: a downlink transmission part, an uplink transmission part and a guard period (GP) part, and the number of OFDM symbols occupied by each part may be configured. In other words, the number of OFDM symbols used for uplink transmission in one slot varies within a range of 0 to 14.
