Abstract

The invention belongs to the technical field of mobile communication, and particularly relates to a dynamic discontinuous reception method, device and system supporting beam search. The dynamic discontinuous reception method comprises the following steps: a user is divided into an activated state, a short sleep state, a long sleep state and a beam search state; and the UE enters a beam search state to perform beam search and feedback after waking up from a sleep state each time, monitors whether a data packet arrives on a physical downlink control channel or not after establishing a beam alignment pair, and ensures that the UE maintains beam alignment with a base station in real-time communication through the independently set beam search state. Meanwhile, due to the independently set beamsearch state, the effective sleep time of the UE can be reduced and the power consumption of the UE is increased; and as the dynamic discontinuous reception method introduces the long sleep durationgrowth factor, if the UE does not receive data after waking up from the long sleep state, the UE enters the long sleep state again, and the sleep duration is increased, so that the increase of energyconsumption caused by the beam search state can be compensated.

Description

technical field

[0001] The invention belongs to the technical field of mobile communication, and relates to a Discontinuous Reception (DRX for short) mechanism that supports beam search and can dynamically adjust long sleep duration, specifically a dynamic discontinuous reception method, device and system that supports beam search . Background technique

[0002] Millimeter wave technology can provide greater bandwidth for 5G, but it has the disadvantages of relatively large path loss and penetration loss. In the 5G system, beamforming technology and millimeter wave communication technology are combined to make up for the defects of millimeter wave itself. , and can further increase the transmission rate of the system.

[0003] The DRX technology is an important technology for saving power consumption of a user equipment (User Equipment, UE for short) in a Long Term Evolution (LTE for short) system. DRX saves energy consumption by controlling the UE to enter the sleep mode ...
