Abstract

The present invention provides methods for incorporating and operating a mesh base station in a wireless network. The mesh base station may utilize common wireless resource allocations as a corresponding wireless base station while transmitting to wireless subscriber stations during the same time period. The mesh base station obtains a data packet from the wireless base station over a backhaul link during a scheduled time period and transmits the data packet to the designated wireless subscriber station during another scheduled time period. The wireless base station and the mesh base station may also receive data packets from wireless subscriber stations during a same time period. A wireless network may be configured with two mesh base stations at an approximate boundary of two adjacent sector coverage areas, where a coverage area is supported by a wireless base station and each mesh base station supports wireless subscriber stations within a coverage radius.

Claims

1. A method, comprising:

sending, by a wireless base station device during a backhaul period preceding a scheduling period, a first wireless signal comprising first data directed to a mesh base station device for facilitating a transmission by the mesh base station device during the scheduling period via a resource of a wireless resource allocation, of a second wireless signal comprising the first data directed to a first wireless subscriber device, wherein the backhaul period is associated with communications corresponding to a backhaul link between the wireless base station device and the mesh base station device;

sending, by the wireless base station device during the scheduling period based on the resource of the wireless resource allocation, a third wireless signal comprising second data different than the first data, wherein the sending the third wireless signal is directed to a second wireless subscriber device;

determining, by the wireless base station device, traffic load data; and

sending, by the wireless base station device, the traffic load data directed to the mesh base station device for facilitating a change of a transmit power of the mesh base station device as a function of the traffic load data.

2. The method of claim 1, further comprising:

receiving, by the wireless base station device from the mesh base station device during another scheduling period, a fourth wireless signal comprising third data associated with the first wireless subscriber device.

3. The method of claim 1, wherein the wireless resource allocation represents an allocation of a frequency.

4. The method of claim 1, wherein the wireless resource allocation represents an allocation of a time slot.

5. A method, comprising:

initiating, by a system comprising a processor, a first wireless transmission of a first data packet between a mesh base station device and a wireless base station device during a first time period;

initiating, by the system, a second wireless transmission of the first data packet between the mesh base station device and a first wireless subscriber device during a second time period via a resource of an assigned resource allocation, wherein the second time period is after the first time period;

initiating, by the system, a third wireless transmission of a second data packet between the wireless base station device and a second wireless subscriber device during the second time period based on the resource of the assigned resource allocation, wherein the second data packet is different than the first data packet;

initiating, by the system, a determination of a traffic load of the wireless base station device; and

in response to initiating a transfer of information representing the traffic load, initiating, by the system, a change of a transmit power of the mesh base station device based on the traffic load data.

6. The method of claim 5, further comprising:

initiating, by the system, a fourth wireless transmission of a third data packet between the mesh base station device and the first wireless subscriber device; and

initiating, by the system, a fifth wireless transmission of the third data packet between the mesh base station device and the wireless base station device.

7. The method of claim 5, further comprising:

facilitating, by the system, a reception, by the mesh base station device, of a set of traffic load data for the wireless base station device; and

facilitating, by the system, a modification of a sensitivity value of the mesh base station device relating to a sensitivity of reception of signals by the mesh base station device based on the set of traffic load data.

8. The method of claim 5, wherein the assigned resource allocation represents an allocation of a frequency.

9. The method of claim 5, wherein the assigned resource allocation represents an allocation of a time slot.

10. A system comprising:

a memory to store instructions; and

a processor, coupled to the memory, that facilitates execution of the instructions to perform operations, comprising;

facilitating a first wireless transfer of a first data packet between a first mesh base station device and a first wireless base station device during a first period;

facilitating a second wireless transfer of the first data packet between the first mesh base station device and a first wireless subscriber device utilizing a first wireless resource allocation during a second period succeeding the first period;

facilitating a third wireless transfer of a second data packet between the first wireless base station device and a second wireless subscriber device utilizing the first wireless resource allocation during the second period; and

facilitating a first transfer of first data between a second mesh base station device and a second wireless base station device during the first period, wherein the second mesh base station device is positioned with respect to the first mesh base station device within a defined distance from a determined boundary between a first sector coverage area associated with the first wireless base station device and a second sector coverage area associated with the second wireless base station device.

11. The system of claim 10, wherein the operations further comprise:

facilitating a second transfer of the first data between the second mesh base station device and a third wireless subscriber device during the second period utilizing a second wireless resource allocation.

12. The system of claim 11, wherein the first wireless resource allocation comprises a first code sequence allocation, and wherein the second wireless resource allocation comprises a second code sequence allocation.

13. The system of claim 11, wherein the first wireless resource allocation comprises a first time slot allocation, and wherein the second wireless resource allocation comprises a second time slot allocation.

14. The system of claim 11, wherein the first wireless subscriber device is located in a sector coverage area associated with the second wireless base station device.

15. The system of claim 11, wherein the operations further comprise:

in response to determining that the first wireless base station device is out of service, transporting a subsequent data packet associated with the first wireless subscriber device between the first mesh base station device and the second wireless base station device.

16. The system of claim 11, wherein the operations further comprise:

facilitating a third transfer of second data between the second wireless base station device and a fourth wireless subscriber device during the second period utilizing the second wireless resource allocation.

17. The system of claim 10, wherein the first wireless subscriber device is located in a sector coverage area associated with the first wireless base station device.
