Flexible radio resource sharing in time and frequency domains among TDD communication systems
First Claim
1. A method, comprising:
- communicating a plurality of first frames using a first communication scheme, each of the first frames having at least one first active time period, wherein communication of the first frames uses a first frequency band; and
communicating a plurality of second frames using a second communication scheme, each of the second frames having at least one second active time period, wherein communication of the second frames uses a second frequency band that at least partially overlaps the first frequency band, andwherein the communication of the first frames and communication of the second frames operate so that at least a portion of the first and second frames overlap in time but the first and second active time periods do not overlap in time.

Abstract
A method includes communicating a number of first frames using a first communication scheme. Each of the first frames has one or more first active time periods. Communication of the first frames uses a first frequency band. The method includes communicating a number of second frames using a second communication scheme. Each of the second frames has one or more second active time periods. Communication of the second frames uses a second frequency band that at least partially overlaps the first frequency band. The communication of the first frames and communication of the second frames operate so that at least a portion of the first and second frames overlap in time but the first and second active time periods do not overlap in time. Apparatus and computer program products are also disclosed. An additional method is disclosed for providing coexistence of two time-division systems.
