Embodiment Construction

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0031] figure 1 A schematic diagram of a scene provided by an embodiment of the present invention is shown. In this scenario, PUCCH 0 of the first HARQ-ACK carrying the first time granularity overlaps with n PUCCHs in time domain resources, and the n PUCCHs do not overlap in time domain resources, and n PUCCHs carry the second time granularity For the second HARQ-ACK of degree, the n PUCCHs are PUCCH 1, PUCCH 2, PUCCH 3, PUCCH 4, ..., PUCCH n. In thi...

Abstract

The embodiment of the invention discloses a physical uplink control channel transmission method and device, equipment and a medium. The method comprises the following steps: if a first PUCCH (PhysicalUplink Control Channel) and a second PUCCH are overlapped on a time domain resource, transmitting a PUCCH bearing HARQ-ACK (Hybrid Automatic Repeat request Acknowledgement) according to a predefinedtransmission rule; wherein the first PUCCH bears a first HARQ-ACK of a first time granularity; wherein the second PUCCH carries a second HARQ-ACK of a second time granularity; wherein the first time granularity is greater than the second time granularity. According to the physical uplink control channel transmission method and device, the equipment and the medium provided by the embodiment of theinvention, the single carrier characteristic of the terminal equipment can be ensured, and the channel estimation performance is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a physical uplink control channel transmission method, device, equipment and medium. Background technique [0002] The main scenarios of the current mobile communication system include: Enhanced Mobile Broadband (Enhanced MobileBroadband, eMBB), Ultra Reliable & Low Latency Communication (Ultra Reliable&Low Latency Communication, URLLC) and Massive Machine Type of Communication (mMTC). [0003] Certain terminal devices may support different services, for example, the terminal device supports both the URLLC service and the eMBB service. For the downlink data transmission of different services, the terminal device can simultaneously construct multiple different Hybrid Automatic Repeat Request ACK (HARQ-ACK) codebooks (codebook), and different HARQ-ACKs can correspond to different times granularity, and can be transmitted on different physical uplink control chan...
