Abstract: Embodiments provide a communication method, terminal, and a base station. The method includes: receiving, by terminal, a reference signal sent by a base station; and obtaining, by the terminal, channel energy of a narrow beam by measuring the reference signal, where the narrow beam is a directional beam. According to the communication method in the embodiments of the present disclosure, the terminal may obtain the channel energy of the narrow beam by measuring the reference signal. Compared with the prior art in which channel energy of a narrow beam is measured on a base station side, a difference is that the terminal can more accurately estimate the channel energy of the narrow beam. That is, the channel energy of the narrow beam estimated by the terminal can more accurately reflect channel quality, and transmission efficiency can be improved.

Abstract: An uplink information sending methods and apparatus are provided. A communication device includes a processor coupled to a non-transitory memory, where the non-transitory memory stores an execution instruction to be executed in the processor. The execution instruction when executed enables the communication device to determine scheduling information and timing advance information. The scheduling information is used to instruct user equipment to send uplink information, and the timing advance information is used to adjust a timing advance used when the user equipment sends the uplink information. The execution instruction when executed further enables the communication device to adjust the timing advance according to the timing advance information, and send the uplink information according to the scheduling information by using an adjusted timing advance.

Abstract: Provided are a system for implementing multiple Radio Access Networks (RANs) convergence and a method thereof. The method includes: an anchor RAN establishes a connection with a User Equipment (UE); the anchor receives a RAB establishment request from a Core Network (CN); the anchor RAN selects an auxiliary RAN; the anchor RAN sends quality of service (QoS) parameters to the auxiliary RAN, so that the auxiliary RAN establishes a connection with the UE according to the QoS parameters, while the anchor RAN keep the connection with the UE. With the methods provided in embodiments for the present disclosure, multiple RANs convergence is implemented, and the UE establishes connections with the anchor RAN and the auxiliary RAN at the same time, so as to improve the peak rate of the UE.
