Problems solved by technology

In practice, when the reference signal used for RRM measurement is sent in the form of a beam, it cannot be measured by using the RRM measurement method in the prior art
And because the high-frequency signal has the characteristics of low penetrating power and fast signal quality attenuation when encountering obstacles, once the high-frequency signal communicated between the UE and the base station deteriorates, it is likely to affect the normal communication between the UE and the base station

Embodiment Construction

[0220] Embodiments of the present invention will be described below with reference to the accompanying drawings.

[0221] At present, cellular communication technologies such as Long Term Evolution (LTE) generally use a frequency band of about 2 GHz or lower, and the LTE-A small cell enhancement (small cell enhancement) standardization project is studying and utilizing a frequency band of 3.5 GHz. An assisted access (LTE assisted access, LAA) technology is researching and utilizing unlicensed spectrum in the 5GHz frequency band. The 802.11ad standard of the Institute of Electrical and Electronics Engineers (IEEE) uses the 60 GHz frequency band for a wireless local area network (wireless local area network, WLAN), and is generally used for short-distance indoor communication at a level of about 10 meters. However, 6 GHz or even higher frequency bands have not been used for cellular communication technology at present. The main challenge of centimeter wave, millimeter wave and ...

Abstract

The invention relates to a radio resource selection method and device. The method comprises the following steps that a terminal obtains a measurement result of a beam, and the terminal sends first indication information for indicating deactivation or deletion of the beam to network equipment, wherein the beam meets a first quality condition, so that the network equipment can deactivate or delete the beam according to the indication of the first indication information, and thus the influence on normal communication between the terminal and the network equipment due to the fact that the communication quality of the beam does not meet the requirement is avoided. In addition, the terminal obtains the measurement result of the beam and sends second indication information for indicating activation or increase of the beam to the network equipment in order to indicate the network equipment to activate or increase the beam with better communication quality for communication with the terminal, so that the communication quality between the terminal and the network equipment can be improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method and device for selecting radio resources. Background technique [0002] While mobile communication technology is developing in the direction of high speed and large data traffic, the demand for spectrum during communication transmission is also increasing. Since the high-band spectrum has a large amount of available bandwidth, it will become an important resource to meet the large-capacity and large-bandwidth requirements of future communications. A target spectrum for further evolution of an evolution system (long term evolution, LTE-A). Among them, the high-frequency spectrum includes centimeter wave (centimeter wave) frequency band and millimeter wave (millimeter wave) frequency band; the centimeter wave frequency band generally refers to the spectrum within the range of 3 GHz to 30 GHz, and the millimeter wave frequency band gener...
