Problems solved by technology

[0004] However, the existing uplink control information is mapped to one subframe during transmission, which cannot meet the requirement of partial subframe transmission of uplink control information in the licensed assisted access (LAA) technology. Unable to meet the needs of new communication technologies, such as mixed downlink and uplink (mixed DL and UL) subframes in the fifth-generation mobile communication technology (5th-Generation, 5G) to transmit uplink control information

Embodiment Construction

[0033] As mentioned in the background technology, the existing uplink control information is mapped to a subframe during transmission, which cannot satisfy partial subframe transmission uplink control in licensed assisted access (LAA) technology. The demand for information cannot meet the needs of new communication technologies, such as the requirements of mixed downlink and uplink (mixed DL and UL) subframes in the fifth-generation mobile communication technology (5th-Generation, 5G) to transmit uplink control information.

[0034] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] figure 1 It is a flowchart of a method for transmitting uplink control information according to an embodiment of the present invention.

Abstract

The invention discloses an uplink control information transmission method, an uplink control information transmission device and a user terminal. The uplink control information transmission method comprises the steps of expanding uplink control information to be transmitted, thus allowing the modulated complex value of the expanded uplink control information to be transmitted to meet a scheduling requirement; multiplying the expanded uplink control information to be transmitted by a random sequence, thus acquiring a multiplication result; and mapping the multiplication result into at least one symbol, and transmitting the symbol to a base station. According to the technical scheme of the method and the device provided by the invention, transmission of the uplink control information is performed by using symbol resources.

Description

technical field [0001] The present invention relates to the communication field, in particular to a transmission method, device and user terminal of uplink control information. Background technique [0002] In a long term evolution (Long term evolution, LTE) system, there are five formats (Format) for uplink control information: Format1 / 1a / 1b, Format 2, Format 3, Format 4 and Format 5. [0003] In the prior art, Format1 / 1a / 1b can be used to bear Scheduling Request (Scheduling Request, SR), Hybrid Automatic Repeat Request (Hybrid Auto Repeat Request, HARQ) Acknowledgment (ACK) / Negative Acknowledgment (Negative Acknowledgment, NACK), Channel State Information (Channel State Information, CSI), the effective information is 1bit or 2bit, after modulation, it is mapped to a subframe through the repetition of 10 symbols (symbol), and through the slots located in each slot (slot) in the subframe Two demodulation reference signal (Demodulation reference signal, DMRS) sequences are d...
