Abstract

Described herein are systems and methods for carrier aggregation deployment and organization in unlicensed bands. A method may comprise scanning, by a transceiver within a base station, channels in a band of interest, reporting, by the transceiver, signal measurement information to the base station, cell searching, by the transceiver, channels in the band of interest, determining channel information for neighboring each channel, and transmitting, by the transceiver, the channel information to the base station.

Claims (61)

1. A method, comprising:

scanning, by a transceiver within a base station, channels in a band of interest;

reporting, by the transceiver, signal measurement information for each of the channels to the base station;

cell searching, by the transceiver, channels in the band of interest;

determining channel information for neighboring cells in each channel, wherein the channel information includes Cell-ID information, system information block (“SIB”) information, and provider information; and

transmitting, by the transceiver, the channel information to the base station.

2. The method of claim 1 , further comprising:

receiving, by the base station, the channel information from a plurality of neighboring cells in the band of interest;

identifying, by the base station, useable channels in an unlicensed band within the band of interest; and

hopping communication from a first channel to a second channel using a secondary cell drop/add mechanism.

3. The method of claim 1 , further comprising:

sending, by the base station, configuration information to a user equipment (“UE”) in the band of interest to read all system information block (“SIB”) information;

reading, by the base station, configuration information from neighboring base stations;

configuring a plurality of further UEs with the neighboring base station configuration information; and

populating a topology map of UE and base station deployment.

4. The method of claim 1 , wherein the signal measurement information includes one of a reference signal received power (“RSRP”), a reference signal received quality (“RSRQ”), a received signal strength indicator (“RSSI”), and a link quality metrics to the base station.

5. A method, comprising:

receiving, by a base station, channel information from a plurality of neighboring cells in a band of interest, wherein the channel information includes Cell-ID information, system information block (“SIB”) information, and provider information;

receiving, by the base station, neighboring base station configuration information to a further base station, wherein the further base station is on a different network from the base station;

identifying, by the base station, useable channels in an unlicensed band within the band of interest;

hopping communication from a first channel to a second channel using a secondary cell drop/add mechanism.

6. The method of claim 5 , wherein the neighboring base station configuration information is transmitted from the base station to the further base station via one of an X2 interface, a RIM transfer, and a OAM server.

7. A base station, comprising:

a transceiver;

a non-transitory memory having a program stored thereon; and

a processor executing the program, wherein the execution of the program causes the processor to perform operations comprising:

scanning, by the transceiver, channels in a band of interest,

reporting, by the transceiver, signal measurement information for each of the channels to the base station,

cell searching, by the transceiver, channels in the band of interest,

determining channel information for neighboring cells in each channel, wherein the channel information includes Cell-ID information, system information block (“SIB”) information, and provider information, and

transmitting, by the transceiver, the channel information to the base station.

8. The base station of claim 7 , wherein the operations further comprise:

receiving, by the base station, the channel information from a plurality of neighboring cells in the band of interest,

identifying, by the base station, useable channels in an unlicensed band within the band of interest, and

hopping communication from a first channel to a second channel using a secondary cell drop/add mechanism.

9. The base station of claim 7 , wherein the operations further comprise:

sending, by the base station, configuration information to a user equipment (“UE”) in the band of interest to read all system information block (“SIB”) information,

reading, by the base station, configuration information from neighboring base stations,

configuring a plurality of further UEs with the neighboring base station configuration information, and

populating a topology map of UE and base station deployment.

10. The base station of claim 7 , wherein the signal measurement information includes one of a reference signal received power (“RSRP”), a reference signal received quality (“RSRQ”), a received signal strength indicator (“RSSI”), and a link quality metrics to the base station.

11. The base station of claim 7 , wherein the operations further comprise:

sending, by the base station, neighboring base station configuration information to a further base station, wherein the further base station is on a different network from the base station.

12. The base station of claim 11 , wherein the neighboring base station configuration information is transmitted from the base station to the further base station via one of an X2 interface, a RIM transfer, and a OAM server.

13. A non-transitory computer readable storage medium with an executable program stored thereon, wherein the program instructs a processor to perform the following operations, comprising:

scanning, by a transceiver within a base station, channels in a band of interest;

reporting, by the transceiver, signal measurement information for each of the channels to the base station;

cell searching, by the transceiver, channels in the band of interest;

determining channel information for neighboring cells in each channel, wherein the channel information includes Cell-ID information, system information block (“SIB”) information, and provider information; and

transmitting, by the transceiver, the channel information to the base station.

14. The computer readable storage medium of claim 13 , wherein the operations further comprise:

receiving, by the base station, the channel information from a plurality of neighboring cells in the band of interest;

identifying, by the base station, useable channels in an unlicensed band within the band of interest; and

hopping communication from a first channel to a second channel using a secondary cell drop/add mechanism.

15. The computer readable storage medium of claim 13 , wherein the operations further comprise:

sending, by the base station, configuration information to a user equipment (“UE”) in the band of interest to read all system information block (“SIB”) information;

reading, by the base station, configuration information from neighboring base stations;

configuring a plurality of further UEs with the neighboring base station configuration information; and

populating a topology map of UE and base station deployment.

16. The computer readable storage medium of claim 13 , wherein the operations further comprise:

sending, by the base station, neighboring base station configuration information to a further base station, wherein the further base station is on a different network from the base station.
