As high definition stream media plays, augmented reality/virtual reality applications are universal, band of the user to mobile cellular communication It is wide that more stringent requirements are proposed.Third generation partner program (third generation partnership project, The abundant millimeter wave band of frequency spectrum resource 3GPP) is included in the 5th generation (fifth generation, 5G) cellular communication system mark Standard is to meet the needs of user's high rate communication.
But millimeter-wave signal will undergo serious path loss when propagating since the high wavelength of frequency is short.In order to gram The problem of taking received signal strength deep fades caused by path loss, an effective approach are to improve letter using beam forming Number directionality sent and received.
This is by realizing in network side and the side UE configuration multi-antenna array and corresponding gain and phase parameter.By In the limited covering range of wave beam, therefore transmission wave beam and reception wave beam must effectively match chain needed for being just able to satisfy communication Road budget.For this purpose, wave beam training is to establish and maintain a wave beam step essential to link.Therefore, user equipment (user equipment, UE) needs to carry out wave beam training to select the reception wave beam of a best performance in the side UE, thus UE It can be communicated by the reception wave beam with the network equipment.Wave beam training process is that the network equipment passes through each broad beam point It Fa Song reference signal, wherein different broad beams correspond to different transmission directions, and UE is transmitted in each broad beam by measuring The signal strength of reference signal carries out broad beam training to determine a broad beam, and UE feeds back the width of selection to the network equipment later Wave beam.Each narrow beam that the network equipment passes through under the broad beam sends reference signal respectively, wherein a narrow beam is corresponding should A transmission direction under broad beam, different narrow beams correspond to different transmission directions.UE passes through transmitted on each narrow beam The signal strengths of measuring reference signals carries out narrow beam training to determine a narrow beam, thus UE can by the narrow beam with The network equipment is communicated.
After UE access cell, if the UE in connected state is in certain time window without transmission/reception data, network Equipment can configure UE and enter discontinuous reception (discontinuous reception, DRX) mode to reduce the power consumption of UE. Under connected state DRX mode, UE is periodically as duration timer (on duration timer, ODT) triggering wakes up and base Physical Downlink Control Channel (physical downlink control is continuously monitored in the determining wave beam of wave beam training Channel, PDCCH) on each time slot scheduling information.At this point, if change in displacement etc. has occurred in UE during suspend mode, it may Cause the predetermined wave beam of suspend mode to failure.If scheduled, the time for extending duration timer is completed physics by UE Transmission/reception of data on DSCH Downlink Shared Channel (physical downlink shared channel, PDSCH)；Otherwise, UE Dormant state will be transferred to after the persistency timer of DRX.When therefore, in order to guarantee that UE wakes up as duration timer triggers The Downlink Control Information (downlink control information, DCI) on PDCCH can be listened to, UE may need It wakes up in advance and carries out the training of second level wave beam, i.e., successively carry out broad beam training and narrow beam training.But UE wake up in advance into Traveling wave Shu Xunlian extends the wakeup time and signaling overheads of UE, increases the power consumption of UE.Particularly, if physical down controls The scheduling information of channel is unrelated with UE, these additional power dissipation overheads will become unnecessary.
Based on this, the embodiment of the present application provides a kind of wave beam training method and device, for reducing the power consumption of UE.The application Terminal device can obtain object beam to link coherence time, historical data flow according to wave beam in embodiment, compared to existing There is terminal device in technology to require to wake up and carry out the mode of complete width two-stage wave beam training in advance every time, the application is real Wakeup time and/or wave beam training precision can be adaptively adjusted according to business scenario by applying terminal device in example, thus protecting The purpose of reduction power consumption may be implemented under the premise of card link robustness.Wherein, method and apparatus are based on the same inventive concept , since the principle that method and device solves the problems, such as is similar, the implementation of apparatus and method can repeat place with cross-reference It repeats no more.
