1. A method, comprising:
- dividing a plurality of time frequency frames into a plurality of slots, each of the plurality of time frequency frames having at least one radio-frequency channel; and
providing time for tuning to another radio-frequency channel between time frequency frames by arranging the plurality of slots so that a service carried in a particular slot within a first tuning time at a first radio-frequency before the end of a time frequency frame k is not transmitted in another slot within a second tuning time after the beginning of a next time frequency frame k+1.

Abstract
A system and method for improved scheduling for time-frequency slicing. According to various embodiments, slot allocations are made so as to guarantee time for tuning between slots. When scheduling services for multiplexes covering multiple radio frequency (RF) channels, time is provided for the receiver to tune to another radio-frequency channel between at least two of the time frequency frames. This is accomplished by arranging slots so that a service carried in a slot within the tuning time before the end of a time frequency frame k is not transmitted in a slot within the tuning time after the beginning of the next time frequency frame k+1.
