Abstract
A method for communication includes communicating between one or more first base stations (28A) and first wireless communication terminals (32A) using a first alternating pattern (56) of downlink time intervals and uplink time intervals. A time offset is selected between the first alternating pattern and a second alternating pattern (60), which is used by one or more second base stations (28B) for communicating with second wireless communication terminals (32B), so as to minimize impact of interference between the first and second wireless communication terminals. The first base stations are synchronized relative to the second base stations according to the selected time offset.
Claims29
A method for communication, comprising:
- communicating between one or more first base stations and first wireless communication terminals using a first alternating pattern of downlink time intervals and uplink time intervals;
- selecting a time offset between the first alternating pattern and a second alternating pattern that is used by one or more second base stations for communicating with second wireless communication terminals, so as to minimize impact of interference between the first and second wireless communication terminals;
- and
- synchronizing the first base stations relative to the second base stations according to the selected time offset.
A communication apparatus, comprising:
- one or more first transceivers, which are configured to communicate with first wireless communication terminals using a first alternating pattern of downlink time intervals and uplink time intervals;
- and
- at least one timing unit, which is configured to synchronize the first alternating pattern relative to a second alternating pattern that is used by one or more second transceivers for communicating with second wireless communication terminals, while applying between the first and second patterns a time offset selected so as to minimize impact of interference between the first and second wireless communication terminals.
A wireless communication terminal, comprising:
- a transceiver, which is configured to communicate with a first base station using a first alternating pattern of downlink time intervals and uplink time intervals, wherein the first alternating pattern is synchronized relative to a second alternating pattern that is used by a second base station for communicating with at least another wireless communication terminal while applying between the first and second patterns a time offset selected so as to minimize impact of interference between the terminal and the other terminal;
- and
- a processor, which is configured to apply an interference mitigation process for reducing residual interference caused by the second pattern.
