Problems solved by technology

However, in the case of multiple transmission and receiving nodes, especially in the ultra-reliable low-latency communication (Ultra-Reliable Low-Latency Communication) scenario, there are usually multiple spatial relationships, corresponding to different beams and repeated transmissions, etc., making the communication environment And resource allocation becomes complicated. At present, there is no effective mechanism for the terminal to decide how to use uplink transmission resources to send uplink transmission for multi-TRP and multi-beam. Therefore, it is also difficult to perform power control and resource allocation for multi-TRP and multi-beam respectively.

Abstract

The invention provides an indication method and device, an uplink transmission method and device, a service node, a terminal and a medium. The indication method comprises the following steps of: sending indication information, wherein the indication information is used for indicating resource configuration of uplink transmission; and receiving uplink control information sent by the terminal.

Description

technical field [0001] The present application relates to a wireless communication network, for example, to an indication method, an uplink transmission method, a device, a serving node, a terminal and a medium. Background technique [0002] In the enhanced Mobile Broadband (eMBB) scenario, the joint transmission technology based on Multiple Transmission and Reception Point (Multi-TRP) is effective for Long Term Evolution (LTE) and Long Term Evolution Enhanced (Long Term Evolution). Term Evolution-Advanced, LTE-A) and New Radio Access Technology (New Radio Access Technology, NR) data traffic has been effectively improved, which can further enhance user experience. However, in the case of multiple transmission and receiving nodes, especially in the ultra-reliable low-latency communication (Ultra-Reliable Low-Latency Communication) scenario, there are usually multiple spatial relationships, corresponding to different beams and repeated transmissions, etc., making the communica...
