A communication system includes: storage to store location information of each of a plurality of devices capable of wireless multi-hop communication, site configuration information including location and size information of an obstacle present at a site of the plurality of devices, and communication quality information between devices; a determination unit determines whether a repeater needs to be added for each of the plurality of devices, based on communication quality information; and a decision unit calculates an expected value related to attenuation of received power between the first and second devices caused by the obstacle, and decides a location for the determination unit to add the repeater based on location information of the first device determined, location information of the second device different from the first device and communicated with the first device through the repeater, the communication quality information between the first and second device, and the site configuration information.

Embodiments of this application provide a communication method, apparatus, and system. The method includes: A terminal device receives first information from a first network device or a second network device, and determines, based on the first information, that it is allowable that the terminal device sends MDT information to the first network device. When it is allowable that the terminal device sends the MDT information to the first network device, the terminal device sends the MDT information to the first network device. This prevents the terminal device from sending the MDT information to the first network device immediately after obtaining the MDT information and avoids disclosure of a network coverage status, thereby effectively and securely using the MDT information.

A method and apparatus for dimensioning a plurality of base stations to be installed within an area such as an enterprise location or a floor space within an enterprise location of an enterprise network. The wireless communication network is a spectrum-controlled network such as a Citizen's Broadband Radio Service (CBRS) network that is spectrum-controlled by a spectrum access server, and the base stations may comprise CBRS devices (CBSDs). A method of allocating radio bands among the base stations is described that effectively utilizes the available spectrum. A domain proxy is connected to communicate with the spectrum access server on behalf of the CBSDs, to inquire regarding spectrum and request spectrum grant.
