Embodiment Construction

[0038] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The following examples are for more clearly explaining the technical solutions of the present invention without limiting the scope of the invention.

[0039] Specifically, in the R16 research phase, multi-TRP / PANEL-based multicast multi-point collaborative transmission technology mainly includes the following two types:

[0040] 1) MULTI-TRP / PANEL transmission technology

[0041] The application of the base station multp / panel is mainly to improve the coverage of the cell edge, providing a more balanced service quality in the service area, and cooperating between multiple TRP / PANELs in different ways. From the perspective of network morphology, network deployment will be more conducive to providing equalization user experience rates, and significantly reduce delay and signaling overhead brought by overworked switching. . In high-frequency sections, each TRP antenna array can be divided into several relatively indepen...

Abstract

The embodiment of the invention discloses a transmission mode indication method and device, a base station, a terminal and a storage medium, and the method comprises the steps: transmitting a signal to terminal UE, so as to enable the UE to determine a transmission mode between the UE and the base station according to the signal, wherein the signaling carries indication information of a transmission configuration indication TCI state, indication information of a redundancy version RV and indication information of a demodulation reference signal DMRS port, and indication information of whetherrepeated sending times are carried or not, or, the signaling carries the indication information, and also carries the indication information of the transmission mode. According to the embodiment of the invention, the indication information is carried in the signaling and is used for indicating the specific transmission mode, so that dynamic switching between different transmission modes can be realized, and the system performance, reliability and resource utilization rate are better improved.

Description

Technical field [0001] The present invention relates to the field of communication technologies, and more particularly to an indication method, apparatus, base station, terminal, and storage medium of transmission modes. Background technique [0002] At present, there are several typical application scenarios, including AR (Augment Reality, Enhance Reality) / VR (Virtual Reality, Virtual Reality). , Industrial automation, traffic control requirements, remote driving, and power distribution control requirements. These URLLC services have higher requirements for reliability, delay and performance. In the R16 research phase, the application based on multi-TRP (Transmission Reception Point, Transmission Receive Point) / Panel (panel) is used, and it is desirable to better enhance the transmission performance of URLLC. [0003] The QoS (QUALITY OF Service, Service Quality) quality requirements of the URLLC business is very high, and many business requirements are in 10 -4 the above. U...
