    摘要: A method and apparatus synchronize a first floating timing reference (207) of a first base station (116) with a timing reference of a second base station (116) of a communication system, without requiring an interruption of normal user traffic through the communication system. A receiver (208) of the first base station monitors (402) a user traffic transmission of the second base station, thereby generating a received signal, and a processing system (206) of the first base station derives (410) a received timing reference (308) from the received signal. The processing system independently adjusts (426, 428) the first floating timing reference according to the received timing reference, without requiring a timing adjustment instruction from a centralized synchronization controller.

    摘要: A method and apparatus assigns and utilizes sets of transmitters (206) to provide radio coverage in dynamically assigned simulcast areas for communicating simultaneously with portable transceivers (122). Transmitters are assigned (704) to the sets such that each set is assigned all transmitters dominant to at least one of the portable transceivers having a message queued therefor. A transmitter is defined to be dominant when it can affect communications with the at least one of the portable transceivers while different data transmissions are being sent from all other transmitters. A subset of the sets is determined (708), wherein no transmitter is assigned more than once in the subset. The sets of the subset are then simulcast (710) such that the transmitters assigned to each of the sets of the subset transmit the message queued for the at least one of the portable transceivers to which the transmitters of the set are dominant.

    摘要: A method and system is disclosed for a device to quickly determine if data is being sent to it. If no data is being sent to the device, the device may return to a sleep mode so as to conserve energy. The present invention includes organizing and transmitting, one at a time, all device destination identifiers. If a message listing search indicates that no message is being sent for a device, the device can continue with any other activity that needs servicing, or if no other activity is pending, it may shut down to conserve power until the next wake up period arrives. If the search returns a positive indication, the count value when the identifier is found can be used to determine the location of the pointer to the message.

    摘要: A wireless communication method and system for efficiently managing paging windows and data messages. The wireless communication system includes at last one network and a plurality of user equipments (UEs). The network maintains a memory that lists UE group identifiers, UE members associated with the UE group identifiers, and paging windows that define time periods during which UEs in particular UE groups are powered up to access data messages. The network schedules UE group identifiers and associated data message pointers within multiple paging windows listed in the network memory such that each UE accesses only one paging window. The network determines whether more than one paging window is necessary for each particular UE, and whether there are any scheduling conflicts between data messages for a particular UE. If there are no conflicts, the UEs are notified of their assigned paging window(s). Otherwise, data messages are rescheduled as necessary.

    摘要: A wireless communication method and antenna system for determining the direction of arrival (DOA) of received signals in azimuth and elevation, (i.e., in three dimensions), to form a beam for transmitting and receiving signals. The system includes two antenna arrays, each having a plurality of antenna elements, two first stage multi-mode-port matrices, at least one second stage multi-mode-port matrix, an azimuth phase detector, an elevation amplitude detector, a plurality of phase shifters and a transceiver. The antenna arrays and the first stage multi-mode-port matrices form a plurality of orthogonal omni-directional modes. Each of the modes has a characteristic phase set. Two of the modes' phases are used to determine DOA in azimuth. The second stage multi-mode-port matrix forms a sum-mode and a difference-mode used to determine the DOA of the received signals in elevation. A beam is formed in the direction of the received signals by adjusting the phase shifters.

    摘要: A method and system for coordinating the use of beam forming between two communicating entities in a wireless communication system is disclosed. The two entities may communicate control information regarding their respective use of beam forming. A correction factor for at least one entity is provided wherein said entity may reduce or withhold its beam adjustment in order to correct any error measured in the alignment of its beam with respect to the beam of the other entity with which it is communicating. Adjustment parameters for adjusting the beams are selected based on conditions surrounding the communication.
