Provided are an information processing device, an information processing method, and a program that enable construction of a wireless system with consideration given to interference with the surroundings of a certain area. This information processing device is provided with: a first evaluation unit that evaluates a distribution of first wireless radio waves entering the inside of a certain area when wireless radio waves are radiated from one or more transmission points set outside the area; and a determination unit that determines, on the basis of the evaluation result regarding the distribution of the first wireless radio waves, information about the disposition candidate position of a wireless base station to be disposed inside the area.

A system is configured to obtain an estimated degree of interference for each of a plurality of beams. The estimated degrees of interference are determined based on properties of received signals transmitted by a transmitter in the first cell using the plurality of beams. The signals have been received by mobile devices while in the serving area of at least one second cell. The system is further configured to take a decision, based on the estimated degrees of interference, whether to avoid usage of one or more beams and/or whether to adjust one or more beams, which are transmitted in a spectrum shared by the cells, determine a set of beams in accordance with the decision, and cause the transmitter to use the set of beams to transmit wireless signals to mobile devices in the first cell.

A terminal includes a reception unit that receives configuration information in a high frequency band higher than or equal to a frequency band of a frequency range 2 (FR2), the FR2 being in a range including a frequency range 1 (FR1) that is a low frequency band and the FR2 that is a high frequency band in a new radio (NR) system; and a control unit that configures at least one of a format of a random access preamble, a sequence of the random access preamble, or a subcarrier spacing applied to a channel on which the random access preamble is to be transmitted, wherein the at least one of the format, the sequence, or the subcarrier spacing is associated with an index included in the configuration information.

The present disclosure provides a new radio base station for a mobile telecommunications system. The new radio base station has a circuitry configured to communicate with at least one user equipment and at least one LTE base station and to establish a new radio cell. The circuitry is further configured to transmit a time division duplexing configuration of the new radio cell to the LTE base station for identifying, based on the received time division duplexing configuration, a coexistence and intermodulation influence on an LTE receiver of the at least one user equipment.

Provided are a communication control device, a communication control method, a communication device, and a communication method capable of changing priority of radio wave use.

A communication control device according to the present disclosure includes: an acquirer configured to acquire application data for changing a priority of radio wave use of a communication device from a second priority lower than a first priority to the first priority on the basis of a right to perform radio wave use with the first priority; a receiver configured to receive a frequency use notification notifying that the communication device is performing the radio wave use with the second priority; and a processor configured to update the priority of the radio wave use by the communication device from the second priority to the first priority in a case where the frequency use notification is received after the application data is acquired.

Methods, apparatuses, and systems for wireless communications supporting dynamic spectrum sharing (DSS) between a first network (e.g., a New Radio (NR) network) and a second network (e.g., a Long Term Evolution (LTE) network) are described. In some aspects, asynchronous operation methods (e.g., methods for offsetting NR resources and LTE resources) are implemented to minimize overlap between resources allocated to synchronization signal blocks (SSBs) and resources allocated to cell reference signals (CRSs) based on time offsets between NR resources and LTE resources. For instance, SSBs in NR may be aligned with multicast-broadcast single frequency network (MBSFN) subframes, SSB allocated resources in NR may be offset to not overlap with CRS allocated resources in LTE, etc.

A method includes performing a first iteration of automated frequency coordination (AFC) using geospatial coordinates of a first access point at a site and a first margin of error to determine a first number of allowed channels for the first access point and performing a second iteration of AFC using the geospatial coordinates of the first access point and a second margin of error to determine a second number of allowed channels for the first access point. The first margin of error is lower than the second margin of error. The method also includes, in response to determining that a difference between the first number and the second number meets a threshold, instructing a second access point at the site to perform AFC using the second margin of error rather than the first margin of error.
