The base station comprises a memory to store a codebook for a transmission rank, a beamforming controller to precode data with a precoding matrix selected from the codebook, and a transmitter to transmit the precoded data to a user equipment, wherein the precoding matrix is selected according to a first description and a second description, which are unique to the precoding matrix, and wherein the second description provides a finer description of the codebook than the first description. Other methods, systems, and apparatuses also are disclosed.
Abstract: A touch-panel cellular phone specifies an invalid area not accepting a user's input operation on a touch panel in advance. The cellular phone detects a user's touch area on the touch panel so as to execute a function pre-assigned to the touch area not encompassed by the invalid area. Additionally, it is possible to reduce and display menu icons in the display area precluding the invalid area on the touch panel. Thus, it is possible to prevent an error operation when a user holding a cellular phone inadvertently touches the touch panel.
Abstract: A method performed by a base station includes generating a request for resource status information, sending the generated request to a neighboring base station, receiving one or more resource status update messages from the neighboring base station in response to the requested resource status information, and performing load balancing operations in dependence upon the received one or more resource status update messages.
Abstract: A decrease is realized in network load caused by a change in selection of location registration device or an increase or decrease in the number of installations, on a circuit switching network side. A mobile communication system includes a mobile station, a packet switching station, and a plurality of location registration devices that perform location management of the mobile station. With respect to the mobile station, after one location registration device is already selected from among the plurality of location registration devices, when the mobile station performs location registration, an NRI (Network Resource Identifier) included in a TMSI (Temporary Mobile Station Identifier) is transmitted to the packet switching station. The packet switching station makes a request for location registration with respect to the one location registration device, based on the NRI.
