    Abstract: PROBLEM TO BE SOLVED: To provide a communication system capable of completing soft hand-off, even when a communication link between an active base station and a mobile station deteriorates before the mobile station receives a handoff direction message. SOLUTION: A device for wireless communications (hereinafter referred to as device) maintains a list of base stations X that the mobile station is in communication with, referred to as an "Active Set". Further, the device maintains another list of base stations Y close to the base stations X in the Active Set. The list is called a "Neighbor Set". A memory in the device includes information which enables the device to demodulate information transmitted from the base stations Y in the Neighbor Set. When a base station Y is included in a pilot strength measurement message (PSMM), the device places the base station Y in the Active Set. COPYRIGHT: (C)2011,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To determine use of receive diversity in a mobile station. SOLUTION: A control system 210 determines a demand level about usage of a communicating resource. A sender transmits a message, which shows the usage of receive diversity in the mobile station based on the determined demand level. After receiving one channel, the receiver 200 determines a transmitting power level of the channel for being at a lower or upper transmit power level limit. Based on the determined transmitting power level, the control system 210 controls the receive diversity by choosing the number of receiver chains 290. COPYRIGHT: (C)2010,JPO&INPIT
