System And Method For Assigning Frequency Resources In A Three-Hop Repeater
First Claim
Patent Images
1. A method of assigning frequency resources in a three-hop repeater, in either a downlink direction or uplink direction on a middle hop of the three-hop repeater, the middle hop being between a network unit and a coverage unit, the method comprising:
- selecting a transmission band for a transmission operation;
scanning the transmission band for interference to the transmission operation; and
dynamically allocating a center frequency and a required bandwidth for the transmission operation within the transmission band, the allocation being based on a lowest interference within the transmission band.

Abstract
A system and method for allocating frequency resources in a three-hop repeater are disclosed. Bandwidth can be allocated asymmetrically, and in non-contiguous blocks for the required bandwidth for a transmission operation. Bandwidth is dynamically allocated on an as-needed basis.

5. A method of dynamically assigning frequency resources in a three-hop repeater in the uplink direction on a middle hop of the three-hop repeater, the middle hop being between a network unit and a coverage unit, the method comprising:
-
detecting a need to assign frequency resources based on a detection of uplink traffic; selecting a transmission band for a transmission operation; scanning the transmission band for interference to the transmission operation; and dynamically allocating a center frequency and a required bandwidth for the transmission operation within the transmission band, the allocation being based on a lowest interference within the transmission band. - View Dependent Claims (6, 7, 8)

9. A method for dynamically de-assigning frequency resources in a three-hop repeater in the downlink direction on a middle hop of a three-hop repeater, the middle hop being between the network unit and coverage unit for boosting and relaying signals between the network unit and the coverage unit, the method comprising:
-
detecting a need to assign frequency resources in the uplink direction based on a detection of uplink traffic; if no additional frequency resources are available in the uplink direction for a transmission operation, finding frequency resources currently assigned in the downlink direction to relay a downlink signal for whose paired uplink transmission no frequency resources was available; and de-assigning the frequency resources in the downlink direction so that the downlink signal is no longer boosted. - View Dependent Claims (10, 11, 12)
