    摘要: A fixed portion (102) of a radio messaging system schedules (602) an inbound message to be transmitted at a first scheduled time on a channel from a portable subscriber unit (122). The channel is monitored (604) at the first scheduled time to receive the inbound message, utilizing a beamforming technique. In response to failing to achieve adequate reception of the inbound message at the first scheduled time, the fixed portion reschedules (608) the inbound message to be transmitted at a second scheduled time, and remonitors (610) the channel at the second scheduled time to receive the inbound message, utilizing an omnidirectional technique.

    摘要: A subscriber unit (122) in a wireless messaging system records (404) a message sequence number corresponding to a message received, and an indication of whether the subscriber unit acknowledged the message. Upon registration with a two-way portion (104) of the wireless messaging system, the subscriber unit reports (532, 526), to the two-way portion, information of a type selected from (a) missing message sequence numbers, and (b) message sequence numbers corresponding to messages received and not acknowledged, the type selected (524) being that which generates a smaller amount of inbound traffic.

    摘要: A radio communication system (100) synchronizes multiple data streams associated with a network of transmitters (102) while maintaining full user traffic. The transmitters transmit (901) a first portion of the user traffic in a simulcast mode during a first time interval, (104) and transmit (903) a second portion of the user traffic in a non-simulcast mode during a second time interval. A monitor receiver (104) is coupled to the transmitters by radio signals for monitoring (905) the second portion of the user traffic transmitted from selected transmitters to determine transmission delays. A controller (108) is coupled to the monitor receiver for adjusting (907) the data streams to equalize the transmission delays (303).

    摘要: A method and apparatus defines (302) a time period Ps following a completion of a demand for one of heating and cooling, the time period sufficient to allow a sensed room temperature Tr measured (309) by a thermostat (500) to stabilize after the completion of the demand; and records (310) an evaluation temperature Te equal to the sensed room temperature measured at an end of the time period. The method and apparatus determines (318, 320, 324, 326), at a future time after recording the evaluation temperature, whether to allow an automatic changeover between heating and cooling modes, based upon a comparison of the evaluation temperature and the sensed room temperature measured at the future time.
