Problems solved by technology

On the other hand, in order to increase the reliability of data transmission, the traditional transmission mechanism can use different transmitting and receiving units to transmit the exact same data waveform to increase the power gain of the receiving end, but this method cannot pass channel coding through multiple transmitting and receiving units. brings additional coding gain
In other words, none of these traditional transmission mechanisms can allow the receiving end (i.e., the user device) to complete a highly reliable transmission block reception with diversity gain within a limited delay time, so it cannot meet the requirements of the URLLC service
[0004] In addition, the traditional transmission mechanism uplink and downlink control signal transmission is only between a single cellular unit and the user device, so the reliability of control signal transmission cannot be increased

Abstract

A base station and user equipment used in a mobile communication system. The base station sends a downlink receiving indication message including a service source configuration and a downlink signal combination parameter setting to the user equipment. A service source configuration indicates multiple service sources. The base station generates a first downlink signal and a second downlink signal based on downlink information. The first downlink signal carries a first part of downlink information, and the second downlink signal carries a second part of downlink information. The base station further transmits the first downlink signal to the user equipment through a first service source among the service sources, and transmits the second downlink signal to the user equipment through a second service source among the service sources.

Description

technical field [0001] The invention relates to a base station and user equipment. Specifically, the base station provides multiple service sources for uplink and downlink multiplexing transmission. In addition, the user equipment can select at least one of the plurality of service sources to transmit the uplink signal to the base station, so as to increase transmission reliability and reduce transmission delay. Background technique [0002] With the rapid development of wireless communication technology, various applications of wireless communication have filled people's lives, and people's demand for wireless communication is also increasing. The next-generation mobile communication system (currently commonly referred to as 5G mobile communication system) proposes new service types, such as: Ultra-reliable and Low Latency Communication (URLLC), Enhanced Mobile Broadband Communication (Enhanced Mobile Broadband ; eMBB), Massive Machine Type Communications (Massive Machine...
