Abstract

In accordance with one or more embodiments of the present disclosure a method for selecting transceivers to provide wireless communication service for a wireless user endpoint comprises determining at least one characteristic of at least one communication channel between a wireless user endpoint and a first plurality of transceivers. The determination of the at least one characteristic is based on a reference signal generated by the wireless user endpoint for reception by the first plurality of transceivers. The method further comprises analyzing the at least one characteristic of the at least one communication channel. The method additionally comprises selecting at least one transceiver of the first plurality of transceivers to provide wireless communication service for the wireless user endpoint. The selection of the at least one transceiver is based on the at least one characteristic of the at least one communication channel.

Claims (31)

1. A method for selecting transceivers to provide wireless communication service for a wireless user endpoint comprising:

receiving a reference signal generated by the wireless user endpoint for reception by a first plurality of transceivers, the first plurality of transceivers each having a wired connection to a control unit to form a distributed antenna system;

determining by the control unit that the reference signal is associated with the first plurality of transceivers, wherein the reference signal is associated with a group identifier (group ID) associated with the first plurality of transceivers and wherein determining that the reference signal is associated with the first plurality of transceivers is based on the group ID;

determining at least one characteristic of at least one communication channel between a wireless user endpoint and a first plurality of transceivers based on the reference signal;

analyzing the at least one characteristic of the at least one communication channel; and

selecting at least one transceiver of the first plurality of transceivers to provide wireless communication service for the wireless user endpoint based on the at least one characteristic of the at least one communication channel.

2. The method of claim 1 , further comprising:

determining that the reference signal is not associated with a second plurality of transceivers; and

ignoring the reference signal as received by the second plurality of transceivers based on the reference signal not being associated with the second plurality of transceivers.

3. The method of claim 2 , wherein determining that the reference signal is not associated with the second plurality of transceivers is based on the group ID.

4. The method of claim 1 , wherein the reference signal is based on a battery status of the wireless user endpoint.

5. The method of claim 1 , wherein the reference signal is based on a speed of the wireless user endpoint.

6. The method of claim 1 , further comprising determining a location of the wireless user endpoint based on the reference signal.

7. The method of claim 1 , wherein the reference signal is based on a unique identifier associated with the wireless user endpoint.

8. The method of claim 1 , wherein the reference signal is based on a unique reference signal pattern associated with the wireless user endpoint.

9. A distributed antenna system comprising:

a first plurality of transceivers configured to receive a reference signal generated by a wireless user endpoint; and

a first control unit communicatively coupled to the first plurality of transceivers using a wired connection to form the distributed antenna system, the first control unit configured to:

determine that the reference signal is associated with the first plurality of transceivers, wherein the reference signal is associated with a group identifier (group ID) associated with the first plurality of transceivers and wherein determining that the reference signal is associated with the first plurality of transceivers is based on the group ID;

determine at least one characteristic of at least one communication channel between the wireless user endpoint and the first plurality of transceivers based on the reference signal generated by the wireless user endpoint;

analyze the at least one characteristic of the at least one communication channel; and

select at least one transceiver of the first plurality of transceivers to provide wireless communication service for the wireless user endpoint based on the at least one characteristic of the at least one communication channel.

10. The distributed antenna system of claim 9 , further comprising:

a second plurality of transceivers configured to receive the reference signal generated by the wireless user endpoint; and

a second control unit communicatively coupled to the second plurality of transceivers and configured to ignore the reference signal as received by the second plurality of transceivers based on a determination that the reference signal is not associated with the second plurality of transceivers.

11. The distributed antenna system of claim 10 , wherein the determination that the reference signal is not associated with the second plurality of transceivers is based on the group ID.

12. The distributed antenna system of claim 9 , wherein the reference signal is based on a battery status of the wireless user endpoint.

13. The distributed antenna system of claim 9 , wherein the reference signal is based on a speed of the wireless user endpoint.

14. The distributed antenna system of claim 9 , wherein the first control unit is further configured to determine a location of the wireless user endpoint based on the reference signal.

15. The distributed antenna system of claim 9 , wherein the reference signal is based on a unique identifier associated with the wireless user endpoint.

16. The distributed antenna system of claim 9 , wherein the reference signal is based on a unique reference signal pattern associated with the wireless user endpoint.
