    Abstract: PROBLEM TO BE SOLVED: To provide methods and apparatus for an efficient two-stage paging wireless communication system.SOLUTION: Wireless terminals are assigned to paging groups. A few first paging message information bits are modulated (using asynchronous modulation) into a first paging signal and communicated from a base station to a wireless terminal. WT wakes up, receives the first paging signal and quickly checks whether its paging group should wait for a second paging signal. If so, the WT is operated to receive the second paging signal; otherwise, the WT goes back to sleep conserving power. The base station modulates several second message information bits (using synchronous modulation) and transmits signals to WTs. From the information in the first and second paging signals, a WT can determine that it is the paged WT and process the paging instructions. The intended paged WT can transmit a reception acknowledgement signal on a dedicated uplink resource.

    解决方案:无线终端被分配给寻呼组。 几个第一寻呼消息信息比特被调制(使用异步调制)到第一寻呼信号中并从基站传送到无线终端。 WT唤醒,接收第一个寻呼信号,并快速检查其寻呼组是否应该等待第二个寻呼信号。 如果是,则操作WT接收第二寻呼信号; 否则,WT回去睡眠节省电力。 基站调制几个第二个消息信息比特(使用同步调制)并向WT发送信号。 根据第一和第二寻呼信号中的信息,WT可以确定它是寻呼WT并处理寻呼指令。 预期的寻呼WT可以在专用上行链路资源上发送接收确认信号。 版权所有(C)2012,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide methods and apparatus for efficient two-stage paging wireless communications systems. SOLUTION: Wireless terminals are assigned to paging groups. A few first paging message information bits are modulated into a first paging signal (using non-coherent modulation) to be communicated from a base station to a wireless terminal. WT rises, receives the first paging signal, and checks whether the paging group should wait for a second paging signal. If so, the WT is operated to receive the second paging signal. Otherwise, the WT goes back to sleep conserving power. The base station modulates a number of second message information bits (using coherent modulation) to transmit signals to WTs. A WT can determine that it is the paged WT from the information in the first and the second paging signals to process paging instructions. The objective invoked WT can transmit an acknowledgement signal on a dedicated uplink resources. COPYRIGHT: (C)2011,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To facilitate utilization of power-based rate signaling for uplink scheduling in a wireless communications system.SOLUTION: A maximum nominal power (e.g., relative maximum transmit power employed on an uplink) is known to both a base station and a mobile device. The base station and the mobile device agree upon the maximum nominal power. Signaling related to the maximum nominal power for utilization on the uplink is provided over a downlink. Selection of a code rate, modulation scheme, and the like for the uplink is effectuated by the mobile device as a function of the maximum nominal power. Moreover, such selection is based at least in part upon an interference cost evaluated by the mobile device.

    Abstract: PROBLEM TO BE SOLVED: To provide methods and apparatuses for determining, communicating and using information which can be used for interference control purposes. SOLUTION: Wireless terminals measure signals transmitted from one or more base stations, e.g., base station sector transmitters (1010, 1014). The measured signals may be, e.g., beacon signals and/or pilot signals. From the measured signals, the wireless terminal generates one or more gain ratios which provide information about the relative gain of the communications channels from different base station sectors to the wireless terminal (1018). On the basis of signal energy measurements and relative gains generated from the energy measures, reports are generated and sent to one or more base stations. COPYRIGHT: (C)2011,JPO&INPIT

    Abstract: Method and apparatus for an access terminal which makes handoff decisions between a number of potential alternative attachment points based on service level indicating metrics are described. The access terminal computes a service level indicating metric differently for a current connection than for a potential alternative connection. A service level indicating metric is a function of loading information and received signal strength. A selection may be made by selecting between attachment points by selecting the attachment point having the highest service level indicating metric from among a plurality of attachment points, one per possible carrier where the attachment point which is considered for a given carrier is the one having the best connection for the given carrier. The access terminal handoff decision approach provides handoff decisions which are nearly as optimal as those which can be achieved using a centralized control node but without the requirement for centralized handoff decisions.

    Abstract: Methods and apparatus for efficient two-stage paging wireless communications systems are described. Wireless terminals (300) are assigned to paging groups. A few first paging message information bits are modulated (using non-coherent modulation) into a first paging signal and communicated from a base station to wireless terminals (200). WTs wake-up, receive the first paging signal and quickly ascertain whether its paging group should expect a second paging signal, if so, the WT is operated to receive the second paging signal; otherwise, the WT goes back to sleep conserving power. The base station modulates (using coherent modulation) a number of second message information bits into a second paging signal and transmits the signal to WTs. From the information in first and second paging signals, a WT can determine that it is the paged WT and process the paging instructions. The intended paged WT can transmit an acknowledgement signal on a dedicated uplink resource.
