Radio communication system, radio station, and radio communication method

Abstract: A radio communication system comprises: a radio receiver including an interference canceller configured to generate a replica of a received signal and remove an interference signal from the received signal, and a frequency offset estimator configured to estimate a carrier frequency offset between a carrier frequency of the interference signal and a carrier frequency of a desired signal included in the received signal; and a radio transmitter including a frequency controller configured to adjust a carrier frequency of a transmitted desired signal to the carrier frequency of the interference signal based on the carrier frequency offset received from the radio receiver.

Communication socket migration among different devices

Abstract: A socket migration architecture for migrating a communication socket among host devices comprises a plurality of migrateable sockets each operating in conjunction with one of a plurality of applications on a plurality of host devices. Each of the applications may utilize a respective migrateable socket to establish peer-to-peer communications with at least one other application. Upon establishment of such communications, the migrateable sockets may form an association link between migrateable sockets operating on different host devices. When a first application and respective first migrateable socket are migrated from a first host device to a second host device, at least one association link established prior to the migration may be used to re-established peer-to-peer communications as part of the migration event.

Mobile station, base station, communications system, and communication method

Abstract: A mobile station comprises a reception unit configured to receive a signal transmitted from a base station; a selection unit configured to select a communication area to perform communication from a plurality of communication areas based on traffic load in the plurality of communication areas where the reception unit can receive the signal; and a notification unit configured to notify the base station of the communication area selected. Another mobile station comprises a reception unit configured to receive a signal transmitted from a base station; a calculation unit configured to calculate a ratio of an average reception quality value over a short period to an average reception quality value over a long period; and a selection unit configured to select a communication area to perform communication from a plurality of communication areas where the reception unit can receive the signal, based on the ratio.

5G Evolution and 6G

Abstract: In this paper, SG evolution, which is the enhancement of SG, and the direction of the evolution of mobile communication technologies for 6G assuming the society and the worldview in the 2030s are examined, and requirements, use cases, and concepts pertaining to technical examination are described [1].

Method of connecting a client device with a router in a wireless communication network

Abstract: A method of connecting a client device with a router in a wireless communication network is disclosed. The method comprises the steps of establishing a link layer connection with a first access point with a first wireless network interface; detecting a second access point with a second wireless network interface; establishing a link layer connection with a second access point with a first wireless network interface; and determining the compatibility between the client device with an access router associated with the second access point.
