Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] An LTE-based indoor / hotspot enhanced resource utilization method, which notifies users whether resources are available by using high-layer signaling. The macro cell sends the system information of the micro cell to the user. The system information includes a bit, and the bit is used to notify the user that when the bit value is 0, the user cannot use the vacated synchronization signal and broadcast information resources. The IE of the micro cell cannot be used; when the bit value is 1, the user can use the vacated resources of the synchronization signal and broadcast information, and the IE ...

Abstract

Disclosed is a resource utilization method based on LTE indoor / hotspot enhancement. According to the method, a user is informed whether a resource is usable by using a high-level signaling; a macrocell sends system information of a microcell to the user, wherein the system information comprises a bit which is used for informing the user, when the bit value is 0, the user can not use resources of idle synchronizing signals and broadcast messages, and the IE of the microcell can not be used, and when the bit value is 1, the user can use resources of idle synchronizing signals and broadcast messages, and the IE of the microcell can be used. According to the technical scheme, the user is informed with the high-level signaling method, the microcell does not send synchronization PSS and SSS or MIB and SIB information, idle resources on the microcell are utilized for data transmission, the user can learn whether idle symbol resources are usable soon after having access to a system, and then time-frequency resources are effectively utilized.

Description

technical field [0001] The present invention relates to the technical field of LTE (Long Term Evolution, long-term evolution) of the mobile Internet, in particular to an indoor / hotspot-enhanced resource utilization method based on LTE that uses high-level signaling to notify users. Background technique [0002] With the development of the mobile Internet and the popularity of smart phones, data services have grown exponentially. For LTE technology, in order to further provide better capacity and improve system performance, low-power "cells" are deployed in areas where data traffic is concentrated, such as indoors and hotspots, as a supplement or enhancement to the large coverage of macro cells. [0003] In view of the isolation between the indoor and the outside world, as well as the characteristics of indoor propagation and coverage, the "cell" covering the indoor can use a frequency different from that of the macro cellular system. [0004] For areas covered by existing m...
