Embodiment approach

[0124] 1. The user equipment maps the obtained uplink control information into two consecutive transmission time units and sends it to the base station, and the base station receives the uplink control information in the two consecutive transmission time units.

[0125] The two consecutive transmission time units are respectively referred to as a first transmission time unit and a second transmission time unit. As an example of this implementation manner, the first transmission time unit may be an S1 subframe, and the second transmission time unit may be an uplink dedicated subframe. The uplink dedicated subframe may be an uplink (Uplink) UL subframe, and all symbols of the UL subframe are used to transmit uplink information. Wherein, all symbols of the UL subframe may be used to transmit uplink control information, or may be used to transmit uplink data, or may be partially used to transmit uplink control information, and the remaining part is used to transmit uplink data. T...

Abstract

The invention discloses an uplink control information sending method and receiving method and devices and is used for improving coverage of a subframe in a 5G system for a PUCCH (Physical Uplink Control Channel). The uplink control information sending method comprises the steps that user equipment obtains uplink control information; and the user equipment maps the uplink control information to atleast two transmission time units and then sends the uplink control information to a network device.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a method and device for sending and receiving uplink control information. Background technique [0002] In the future fifth-generation mobile communication system (5G), in order to enable fast transmission and fast control information feedback, a new type of subframe may be introduced, that is, self-contained subframe (Self-contained Subframe), the self-contained subframe It may include subframes of the first type and / or subframes of the second type. Hereinafter, the subframes of the first type are referred to as S1 subframes for short, and the subframes of the second type are referred to as S2 subframes for short. Both the S1 subframe and the S2 subframe include symbols for downlink transmission, a guard period (Guard Period, GP) and symbols for uplink transmission. [0003] Among them, the symbols used for downlink transmission in the S1 subframe are mainly used...
