1. A method comprising:
- transmitting a message at a first time slot of a frequency hopping sequence;
determining a second time slot in the frequency hopping sequence at which a response to the message is expected;
entering a sleep mode;
emerging from the sleep mode to monitor for the response to the message at the second time slot; and
wherein a same frequency is associated with the both the first and second time slots.

Abstract
Systems, apparatuses and methods for managing message communications in systems employing frequency hopping. One method according to the invention involves transmitting a message via a frequency of a frequency hopping sequence, and determining when the same frequency will reoccur in the frequency hopping sequence. Relevant portions of the device enter a sleep mode, and the device emerges from the sleep mode when the frequency at which the message was transmitted reoccurs in the frequency hopping sequence. The device monitors for a response to the message via the frequency at which the message was transmitted when the frequency reoccurs in the frequency hopping sequence.

8. An apparatus comprising:
-
a receiver; a transmitter configured to transmit a message at a first time slot of a frequency hopping sequence; a timer module configured to determine a second time slot in the frequency hopping sequence at which a response to the message is expected; a sleep control module configured to cause at least the receiver to enter a sleep mode, and to cause the receiver to emerge from the sleep mode when the timer module indicates that the second time slot has arrived; wherein the receiver is configured to monitor for a response to the message when the receiver has emerged from the sleep mode; and wherein a same frequency is associated with the both the first and second time slots. - View Dependent Claims (9, 10)
