Embodiment 1

[0550] See figure 1 An embodiment of the present invention provides a PUCCH transmission method, which may be used to perform PUCCH transmission between devices, for example, a user equipment (User Equipment, UE) may perform PUCCH transmission to a base station. Wherein, the user equipment may be a personal computer (PC), a notebook, a mobile phone, an Internet of Things device, a wearable device, etc., and the embodiment of the present invention does not limit the specific type of the user equipment. The base station can be any receiving node, such as TRP, traditional base station, relay node and so on.

[0551] The flow of the PUCCH transmission method in the embodiment of the present invention is described as follows:

[0552] Step 101: Determine an uplink beam used for PUCCH transmission based on the obtained indication signaling.

[0553] Step 102: Perform PUCCH transmission with the determined uplink beam.

[0554] In the embodiment of the present invention, the uplin...

Embodiment 2

[0653] See figure 2 , based on the same inventive concept as in Embodiment 1, this embodiment of the present invention provides another PUCCH transmission method, which includes the following steps.

[0654] Step 201: Send an indication signaling, the indication signaling is used for the terminal to determine the uplink beam used for PUCCH transmission.

[0655] Step 202: Determine that the terminal transmits the PUCCH according to the uplink beam determined according to the indication signaling.

[0656] In a specific implementation process, the terminal may be a terminal applying the method in Embodiment 1, which is not limited in this embodiment of the present invention.

[0657] In a possible implementation manner, sending the indication signaling, the indication signaling is used for the terminal to determine the uplink beam used for PUCCH transmission, including:

[0658] The indication signaling indicates the beam pair relationship BPL, and the BPL is used to determi...

Embodiment 3

[0747] See image 3 , an embodiment of the present invention provides a user equipment, where the user equipment includes a determining unit 301 and a transmitting unit 302 . in:

[0748] A determining unit 301, configured to determine an uplink beam used for PUCCH transmission based on the obtained indication signaling;

[0749] The transmission unit 302 is configured to perform PUCCH transmission with the determined uplink beam.

[0750] In a possible implementation manner, the determining unit 301 is configured to determine the beam pair relationship BPL based on the obtained instruction, and the BPL is used to determine the relationship between the uplink beam or the demodulation reference signal DMRS port of the PUCCH used for PUCCH transmission and the first Quasi-co-located QCL relationships of ports on resources of reference signals;

[0751] The transmission unit 302 is configured to perform PUCCH transmission with the uplink beam corresponding to the BPL; or, acco...

Abstract

Embodiments of the present invention provide a PUCCH transmission method, user equipment and device to solve the technical problem that there is no clear method or device in the prior art to support the PUCCH transmission scenario in the new wireless communication system. Wherein, a PUCCH transmission method includes: determining an uplink beam beam used for PUCCH transmission based on the obtained indication signaling; performing PUCCH transmission with the determined uplink beam.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a PUCCH transmission method, user equipment and device. Background technique [0002] With the development and change of mobile communication service requirements, organizations such as the International Telecommunication Union (ITU) and the 3rd Generation Partnership Project (3GPP) have begun to study new wireless communication systems, such as the fifth generation wireless communication System (5Generation New RAT, 5G NR). [0003] A new working scenario is defined in the new wireless communication system. Two transmitting and receiving nodes (TRP, Transmission and Reception Point) respectively transmit the Physical Downlink Control Channel (PDCCH, Physical Downlink Control Channel) and the corresponding physical downlink control channel to the same terminal. Downlink Shared Channel (PDSCH, PhysicalDownlink Shared Channel). PDCCH and PDSCH from different TR...
