Problems solved by technology
[0004] The embodiment of the present application provides a method and device for sending and receiving uplink control information, which is used to solve the problem of how to send the three different UCIs in the prior art when the OFDM symbols occupied by the three different UCIs in one time slot partially overlap. Problems with UCIs
[0006] Therefore, the method provided by the embodiment of the present application solves the problem of how to transmit the three different UCIs when the OFDM symbols occupied by the three different UCIs in one time slot partially overlap, and can realize the maintenance of the uplink transmission of the terminal equipment. Single-carrier characteristics, while ensuring that UCI can be correctly received by network devices

Embodiment Construction
[0087] Embodiments of the present application are described below in conjunction with the accompanying drawings.
[0088] The embodiment of the present application can be applied to a 5G system. The network elements involved in this embodiment of the present application include network devices and terminal devices.
[0089] Wherein, as a specific implementation form of an access network (access network, AN), the network device may also be called an access node, and if it is in the form of wireless access, it is called a radio access network (radio access network, RAN). Provide wireless access services for terminal equipment. Specifically, the access node may be a base station in a global system for mobile communication (GSM) system or a code division multiple access (code division multiple access, CDMA) system, or may be a wideband code division multiple access (wideband code division multiple access, The base station (NodeB) in the WCDMA) system can also be the evolved base...

The invention discloses an uplink control information sending method and device and an uplink control information receiving method and device. The sending method comprises the following steps: determining a first uplink control channel PUCCH resource set according to the load size of a hybrid automatic repeat request response HARQ-ACK; determining a first PUCCH resource in a first PUCCH resource set according to an ARI field included in the first information, wherein the first PUCCH resource and the second PUCCH resource are partially overlapped in time, or, the first PUCCH resource and the second PUCCH resource are not overlapped in time, the first PUCCH resource and the second PUCCH resource are partially overlapped with the at least one third PUCCH resource in time respectively, the second PUCCH resource is used for transmitting channel state information CSI, and the at least one third PUCCH resource is used for transmitting at least one positive scheduling request SR; determining asecond PUCCH resource set according to the total load; determining a fourth PUCCH resource in the second PUCCH resource set according to the ARI field; and sending the HARQ-ACK, the CSI and the at least one SR state to the network equipment on the fourth PUCCH resource, wherein the SR state is a positive SR or a negative SR.
Description
[0001] This application claims the priority of the Chinese patent application submitted to the State Intellectual Property Office of China on April 4, 2018, with the application number 201810302333.8 and the application name "A Method and Device for Sending and Receiving Uplink Control Information", the entire content of which Incorporated in this application by reference. technical field [0002] The present application relates to the technical field of wireless communication, and in particular to a method and device for sending and receiving uplink control information. Background technique [0003] In the fifth generation (the 5th generation, 5G) mobile communication system, a physical uplink control channel (physical uplink control channel, PUCCH) is sent within a time slot (slot). In one time slot, both the initial orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) symbol of the PUCCH and the number of OFDM symbols occupied by t...
