Uplink control channel sending method and device, server and terminal equipment

Abstract

Provided in an embodiment of the present application are a method, device and terminal device for sending an uplink control channel, in the method, the terminal device determines the number of PRBs occupied by each PUCCH resource, determines the identifier of the used PUCCH resource, and then sends the PUCCH resource to the terminal device according to the identifier of the PUCCH resource and the number of PRBs. The method comprises the following steps: determining an identifier of a PRB (Physical Resource Block) where a first hop for transmitting a PUCCH (Physical Uplink Control Channel) is located, an identifier of a PRB where a second hop for transmitting the PUCCH is located and an initial cyclic shift identifier used for transmitting the PUCCH, and finally, transmitting the PUCCH on the PRBs of the number according to the identifier of the PRB where the first hop is located, the identifier of the PRB where the second hop is located and the initial cyclic shift identifier. Therefore, the terminal equipment can determine the number of PRBs occupied by the PUCCH resource before the RRC connection is established, the number of PRBs occupied by the PUCCH format 0 and the PUCCH format 1 is increased, the sending power of the terminal equipment is improved, and the uplink coverage range of the terminal equipment is expanded.

Description

technical field [0001] The embodiments of the present application relate to the field of communications technologies, and in particular, to a method, an apparatus, and a terminal device for sending an uplink control channel. Background technique [0002] Before a radio resource control (RRC) connection is established, the base station cannot configure a physical uplink control channel (PUCCH) resource set for user equipment (UE) through high-layer RRC signaling, so the protocol is used. The way to predefine the PUCCH resource set. At the same time, before the RRC connection is established, the UE's requirement for PUCCH is only the response information used to feed back the signaling for establishing the RRC connection, so the PUCCH resources in the predefined PUCCH resource set only need to carry 1-2 bits of response information. That is, the PUCCH resources in the predefined PUCCH resource set are only composed of PUCCH format 0 and PUCCH format 1. [0003] In the relate...

Problems solved by technology

[0004] However, the transmit power of the base station or terminal on the unlicensed spectrum is limited by the power spectral density (power spectral density, PSD), for example: in Korea, its PSD is 13dB / MHz, which means that if the frequency domain width of the signal is 1MHz, The maximum transmit power of UE is only 13dBm

The existing related technologies only support that PUCCH format 0 and PUCCH format 1 occupy one PRB in the frequency domain. If PUCCH format 0 and PUCCH format 1 work on the 60GHz unlicensed spectrum, the maximum transmit power of the UE will be limited and cannot reach the UE's maximum transmit power. The maximum transmit power, which will affect the UE's uplink coverage
