Abstract
A transmitter, for controlling at least one receiver by intermittently transmitting groups of messages. The transmitter includes a controller arranged to provide intermittently groups of messages for transmission. Each of said groups includes a plurality of messages in series and separated by time intervals, wherein each of the plurality of messages in a group includes control information such that control of the receiver can be effected by reception of any one of the plurality of messages in the group. The invention increases the efficiency with which control messages can be transmitted without markedly increasing the power consumption of transceivers in a radio frequency network.
Claims26
A transmitter for controlling at least one receiver by intermittently transmitting groups of messages, comprising:
- a transmitter unit which transmits messages;
- and
- control means arranged to provide intermittently groups of messages for transmission by said transmitter unit,
- wherein each group of said groups comprises:
- a plurality of messages in series and separated by predetermined time intervals, and
- wherein each of the plurality of messages in said group comprises:
- control information such that the same control of the receiver can be effected by reception of any one of the plurality of messages in said group.
4 more elements
A communication system comprising:
- a transmitter for controlling at least one receiver by intermittently transmitting groups of messages,
- wherein said transmitter comprises:
- a transmitter unit which transmits messages, and
- first control means arranged to provide intermittently groups of messages for transmission by said transmitter unit,
- wherein each group of said groups comprises:
- a plurality of messages in series and separated by time intervals,
- wherein each of the plurality of messages in said group comprises:
- control information such that the same control of the receiver can be effected by reception of any one of the plurality of messages in said group;
- and
- at least one receiver for periodically receiving messages having control information,
- wherein the receiver comprises:
- second control means arranged to control the operation of the receiver based on received messages,
- a clock for providing a time reference to said second control means, and
- receiver and synchronization means responsive, when enabled, to the control information in a received message to indicate to said second control means reception of said message,
- wherein said second control means periodically enables for a predetermined duration said receiver and synchronization means to receive one message in each group, and
- wherein said receiver adapts to a variation after receipt of one of the messages in a group.
