Abstract

A wireless communication network redirects User Equipment (UE) from a source frequency band to a target frequency band. An originating wireless repeater in a wireless repeater chain wirelessly receives wireless source signals including source overhead over the source frequency band and wirelessly receives wireless target signals including target overhead over the target frequency band. The originating wireless repeater wirelessly transmits the wireless source signals including the source overhead over the source frequency band and wirelessly transmits the wireless target signals including the target overhead over the target frequency band. A terminating wireless repeater in the wireless repeater chain wirelessly receives the wireless target signals including the target overhead over the target frequency band and wirelessly transmits the wireless target signals including the target overhead over the target frequency band. The terminating wireless repeater wirelessly transmits modified source overhead over the source frequency band indicating redirection to the target frequency band.

Claims

1. A method of operating wireless communication network to redirect User Equipment (UE) from a source frequency band to a target frequency band in a wireless repeater chain, the method comprising:

a wireless base station wirelessly transmitting an instruction comprising modified source overhead that indicates UE redirection to the target frequency band;

a terminating wireless repeater in the wireless repeater chain wirelessly receiving the instruction comprising the modified source overhead that indicates the UE redirection to the target frequency band;

the terminating wireless repeater wirelessly receiving target wireless signals including target overhead over the target frequency band and wirelessly transmitting the target wireless signals including the target overhead over the target frequency band;

in response to the instruction, the terminating wireless repeater generating the modified source overhead that indicates UE redirection to the target frequency band and wirelessly transmitting the modified source overhead over the source frequency band; and

the UE wirelessly receiving the modified source overhead over the source frequency band from the terminating wireless repeater, and in response, the UE redirecting from the source frequency band to the target frequency band and wirelessly receiving the target wireless signals including the target overhead over the target frequency band.

2. The method of claim 1 wherein the terminating wireless repeater generating and wirelessly transmitting the modified source overhead comprises the terminating wireless repeater generating and wirelessly transmitting the modified source overhead that indicates redirection to a target frequency channel in the target frequency band.

3. The method of claim 1 wherein the terminating wireless repeater generating and wirelessly transmitting the modified source overhead comprises the terminating wireless repeater generating and wirelessly transmitting the modified source overhead that indicates a number of target frequency channels in the target frequency band.

4. The method of claim 1 wherein the terminating wireless repeater generating the modified source overhead comprises a power amplifier in the terminating wireless repeater generating the modified source overhead.

5. The method of claim 1 further comprising the terminating wireless repeater in the wireless repeater chain wirelessly receiving the source overhead over the source frequency band and wherein wirelessly transmitting the modified source overhead comprises wirelessly transmitting at least a portion of the received source overhead in the modified source overhead.

6. The method of claim 1 wherein the terminating wireless repeater wirelessly transmitting the modified source overhead comprises the terminating wireless repeater wirelessly transmitting the modified source overhead in an Orthogonal Frequency Division Multiplexing (OFDM) Primary Synchronization Signal (PSS).

7. A wireless communication network to redirect User Equipment (UE) from a source frequency band to a target frequency band in a wireless repeater chain, the wireless communication network comprising:

a wireless base station configured to wirelessly transmit an instruction comprising modified source overhead that indicates UE redirection to the target frequency band;

in the wireless repeater chain, a terminating wireless repeater configured to wirelessly receive the instruction comprising the modified source overhead that indicates the UE redirection to the target frequency band;

in the wireless repeater chain, the a terminating wireless repeater configured to wirelessly receive target wireless signals including target overhead over the target frequency band and wirelessly transmit the target wireless signals including the target overhead over the target frequency band;

in the wireless repeater chain and in response to the instruction, the terminating wireless repeater configured to generate the modified source overhead that indicates the UE redirection to the target frequency band and wirelessly transmit the modified source overhead over the source frequency band; and

the UE configured to wirelessly receive the modified source overhead over the source frequency band from the terminating wireless repeater, and in response, redirect from the source frequency band to the target frequency band and wirelessly receive the target wireless signals including the target overhead over the target frequency band.

8. The wireless communication network of claim 7 wherein the terminating wireless repeater is configured to generate and wirelessly transmit the modified source overhead that indicates redirection to a target frequency channel in the target frequency band.

9. The wireless communication network of claim 7 wherein the terminating wireless repeater is configured to generate and wirelessly transmit the modified source overhead that indicates a number of target frequency channels in the target frequency band.

10. The wireless communication network of claim 7 wherein the terminating wireless repeater comprises a power amplifier configured to generate the modified source overhead.

11. The wireless communication network of claim 7 further comprising the terminating wireless repeater in the wireless repeater chain configured to wirelessly receive the source overhead over the source frequency band and to wirelessly transmit at least a portion of the received source overhead in the modified source overhead.

12. The wireless communication network of claim 7 wherein the terminating wireless repeater is configured to wirelessly transmit the modified source overhead in an Orthogonal Frequency Division Multiplexing (OFDM) Primary Synchronization Signal (PSS).
