Problems solved by technology
In some scenarios that require fast access or fast reconnection (such as low-latency high-reliability scenarios, uRLLC), since the scanning speed of the antenna beam is limited by the length of the wireless frame, especially in the case of using a narrow beam, the user needs to obtain The synchronization signal and the remaining minimum system information (RMSI: Remaining Minimum System Information) control resource set (CORESET: Control-Resource Set) may have a relatively long waiting time, which usually cannot meet the requirements of fast access to the system

Embodiment Construction
[0038] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and examples.
[0039] The present invention proposes an RMSICORESET transmission method based on multi-beam scanning for high-band Massive MIMO communication scenarios. The gNB end configures at least two beams with the same beam shape and different directions, and uses the configured beams to assign The RMSI CORESET signal is sent in parallel in the form of scanning. The method proposed in this application can enable the UE to quickly acquire the remaining minimum system information without causing inter-cell interference. Corresponding to the above-mentioned method for sending the RMSI CORESET signal at the gNB side, this application also provides the corresponding information acquisition method at the UE side.
[0040] For the gNB side in the high-band Massi...

Description
technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and device for transmitting a set of remaining minimum system information control resources based on multi-beam scanning. Background technique [0002] In order to meet the high traffic density requirements of the future 5G communication network, the use of high-frequency continuous bandwidth from 6GHz to 52.6GHz is an inevitable choice for 5G communication, but the propagation of high-frequency signals has strong attenuation characteristics, short transmission distance and penetration and diffraction capabilities Poor, especially during the search and synchronization process when the UE initially accesses the cell, the UE does not have any channel information and gNB-related information. In order to improve the coverage, the base station usually adopts the method of increasing the transmission power, but this also increases the Interference from n...
