Problems solved by technology

For example, in order to meet the requirements of low cost and low complexity, the number of receiving antennas of Redcap UE can be limited
However, the reduction in the number of receiving antennas for Redcap UE will cause coverage loss and affect communication performance

Embodiment approach

[0202] In an implementation manner, the downlink transmission method further includes:

[0203] In step S51, a first parameter and a second parameter are determined.

[0204] Wherein, the first parameter is used to indicate the number of repeated PDCCH transmissions of the first type of terminal. The second parameter is used to indicate the number of repeated PDSCH transmissions of the first type of terminal.

[0205] In step S52, the first parameter and the second parameter are sent.

[0206] Further, in the embodiment of the present disclosure, the network device may also determine a third parameter, the third parameter is used to indicate the time slot offset of the first time domain position relative to the second time domain position, the first time domain position is the PDSCH transmission The second time domain position is the time domain position of PDCCH transmission.

[0207] In an implementation manner, the first time domain position is the time domain position o...

Abstract

The invention relates to a downlink transmission method, a downlink transmission device and a storage medium. The downlink transmission method is applied to a terminal, and comprises the following steps: determining a first parameter which is used for indicating the number of times of repeated transmission of a physical downlink control channel of a first type of terminal; and performing downlinktransmission based on the first parameter. Through adoption of the method and the device, repeated transmission of the physical downlink control channel is realized, so that coverage increase can be realized, and coverage loss caused by factors such as reduction of the number of antennas is made up.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular, to a downlink transmission method, a downlink transmission device, and a storage medium. Background technique [0002] With the continuous development of the Internet of Things business, such as video surveillance, smart home, wearable devices and industrial sensor monitoring and other services are popular. These services usually require a rate of tens to 100M, and also have relatively high requirements for delay. Therefore, in related technologies, machine type communication (Machine Type Communication, MTC), narrowband Internet of things (Narrowband Internet of things, NB-IoT ) technology is difficult to meet the requirements. Therefore, it is proposed to design a new type of terminal in 5G New Radio (NR) to cover mid-end IoT devices. In the current 3GPP standardization, this new type of terminal is called Reduced capability UE or Redcap UE for short. [00...
