AI Technical Summary

Problems solved by technology

However, beamforming technology still has its limitations
For example, if the user device moves out of the beam range of the original service due to fast movement or turning, problems such as poor transmission quality and even service interruption may still occur

Embodiment Construction

[0026] figure 1 A schematic diagram of a wireless communication system 100 according to an embodiment of the present disclosure is shown. To simplify the description, figure 1 Only a base station 102 and a user device 104 are shown in the wireless communication system 100 . However, those skilled in the art can easily understand that, in an actual use environment, the wireless communication system 100 may include one or more base stations and one or more user equipments, wherein each base station may provide services to multiple user equipments .

[0027] The base station 102 and the user equipment 104 may include a transceiver and a processor, respectively. The transceiver may be responsible for the transmission and reception of signals. The processor is coupled to the transceiver and can be used to execute the method of the embodiments of the present disclosure. However, those with ordinary knowledge in the technical field should understand that the method operations me...

Abstract

A base station, a user device, a transmission control method for the base station, and a data transmission method for the user device. The base station generates an uplink resource association message, and the uplink resource association message is used to indicate the association between multiple downlink transmission beams and multiple uplink beam recovery transmission resources. The base station sends an uplink resource association message to the user equipment. When the user equipment detects that a downlink transmission beam failure event occurs in a beam pair connection with the base station, the user equipment performs uplink transmission on the first uplink beam recovery transmission resource among the plurality of uplink beam recovery transmission resources. The base station sends a beam planning message in response to the uplink transmission of the user equipment, so as to plan the first downlink transmission beam associated with the first uplink beam recovery transmission resource into one or more beam pair connections.

Description

【Technical field】 [0001] The present disclosure relates to a base station, a user equipment, a transmission control method for the base station, and a data transmission method for the user equipment. 【Background technique】 [0002] With the development of wireless communication technology, more and more users can transmit data through various mobile devices (such as smart phones, tablet computers, etc.) to meet the needs of communication, multimedia audio and video, and the like. In order to ensure that high-quality mobile communication services can be provided to users, future wireless communication standards (eg, the 5th generation mobile communication system) are formulated in the direction of using high-frequency carriers. [0003] However, using high frequency spectrum (eg 28GHz-100GHz) will face severe signal attenuation. To solve this problem, some developers propose a beamforming technology, which enables the base station to form a directional beam and track the mov...
