Embodiment Construction

[0047] As mentioned above, when the physical downlink control channel (Physical Downlink Control Channel, PDCCH) supporting sub-slots is repeatedly transmitted in the URLLC-based system, how to configure the transmission is a problem. The PUCCH uploading method in the prior art has low flexibility.

[0048] Currently, for the PUCCH transmission of the URLLC of Rel-15, the following five PUCCH formats are supported, as listed in Table 1. The PUCCH in each slot can only be repeatedly transmitted in units of slots, and the number of repetitions is uniformly configured by RRC signaling, that is, formats 1, 3, and 4 can only use a unified number of repetitions, so Less flexibility.

[0049] Referring to Table 1, Table 1 shows the PUCCH formats supported by the URLLC PUCCH transmission of Rel-15 in the prior art.

Abstract

A PUCCH (Physical Uplink Control Channel) data uploading method and device, a storage medium, a terminal and a base station, the method comprising: receiving repetition indication information, the repetition indication information being used for indicating repetition times and repetition types of uploading a PUCCH; and according to the repetition indication information, uploading the PUCCH data by adopting the repetition times and the repetition type. According to the method and the device, the repetition frequency and the repetition type flexibility of uploading the PUCCH can be effectively improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for uploading PUCCH data, a storage medium, a terminal, and a base station. Background technique [0002] In a long term evolution (Long Term Evolution, LTE) system, coordinated multi-point transmission technology is supported as an effective method for increasing user data transmission rate, and is continuously enhanced in subsequent versions of the LTE protocol. [0003] During the standardization process of New Radio (NR), a similar CoMP transmission technology is called Transmitter Receiver Point (TRP) transmission. In the Rel-15 (Release-15) version, the multi-TRP transmission only enhances the downlink transmission of Ultra Reliable Low Latency Communication (URLLC) and Enhanced Mobile Broadband (EMBB) systems, The uplink transmission of the URLLC and EMBB systems has not been enhanced. Currently, the uplink transmission of the URLLC of t...
