Abstract

Systems, methods, and access nodes are provided for providing a filter defined carrier. The systems and methods include selecting, at an access node, a frequency range encompassing multiple spectrum blocks and applying a digital filter to the frequency range to eliminate at least one spectrum block within the frequency range to create a carrier having a profile. The method additionally includes comparing the profile to capabilities of a wireless device and allowing the wireless device to connect to the access node in compliance with the profile and its capabilities.

Claims (33)

1 . A method comprising:

selecting, at an access node, a frequency range encompassing multiple spectrum blocks, the frequency range encompassing multiple frequency bands;

applying a digital filter to the frequency range to eliminate at least one unusable spectrum block within the frequency range to thereby define a single carrier without using carrier aggregation of multiple carriers combining available spectrum blocks from the multiple frequency bands;

matching wireless device capabilities of a wireless device with the multiple available spectrum blocks of the single carrier that is defined without using carrier aggregation of multiple carriers to determine matching spectrum blocks from the single carrier; and

allowing the wireless device to connect to the access node utilizing the matching spectrum blocks from the multiple available spectrum blocks of the multiple frequency bands within the single carrier without using carrier aggregation of multiple carriers, the available spectrum blocks not including the at least one unusable spectrum block eliminated by the digital filter.

2 . The method of claim 1 , further comprising receiving a user equipment (UE) capability report from the wireless device.

3 . The method of claim 2 , further comprising comparing the available spectrum blocks with received UE capabilities from the UE capability report.

4 . The method of claim 3 , further comprising selecting spectrum blocks available to the wireless device as the matching spectrum blocks based on the comparison.

5 . The method of claim 4 , further comprising sending information identifying the selected spectrum blocks to the wireless device.

6 . The method of claim 1 , further comprising communicating information identifying the available spectrum blocks to the wireless device during an attach procedure.

7 . The method of claim 1 , further comprising allowing the wireless device to connect to the access node using multiple available spectrum blocks within the carrier.

8 . The method of claim 1 , further comprising communicating the available spectrum blocks to the wireless device using a system information block (SIB).

9 . The method of claim 1 , further comprising defining a profile based on the available spectrum blocks and comparing the profile to a received user equipment (UE) capability report.

10 . The method of claim 1 further, comprising defining at least one additional carrier encompassing multiple frequency bands.

11 . An access node comprising:

at least one processor performing operations including:

selecting a frequency range encompassing multiple spectrum blocks, the frequency range encompassing multiple frequency bands;

applying a digital filter to the frequency range to eliminate at least one unusable spectrum block within the frequency range, thereby defining a single carrier without using carrier aggregation of multiple carriers combining available spectrum blocks from the multiple frequency bands;

matching wireless device capabilities of a wireless device with the multiple available spectrum blocks of the single carrier that is defined without using carrier aggregation of multiple carriers to determine matching spectrum blocks from the single carrier; and

allowing the wireless device to connect to the access node using the matching spectrum blocks from the multiple available spectrum blocks of the multiple frequency bands of the single carrier, without using carrier aggregation of multiple carriers, the available spectrum blocks not including the at least one unusable spectrum block eliminated by the digital filter.

12 . The access node of claim 11 , the operations further comprising receiving a user equipment UE capability report from the wireless device.

13 . The access node of claim 12 , the operations further comprising comparing the available spectrum blocks with received UE capabilities from the UE capability report.

14 . The access node of claim 13 , the operations further comprising selecting spectrum blocks available to the wireless device based on the comparison.

15 . The access node of claim 14 , the operations further comprising sending information identifying the selected spectrum blocks to the wireless device.

16 . The access node of claim 11 , the operations further comprising communicating information identifying the available spectrum blocks to the wireless device during an attach procedure.

17 . The access node of claim 11 , the operations further comprising allowing the wireless device to connect to the access node using multiple available spectrum blocks within the carrier.

18 . A method comprising:

selecting, at an access node, a frequency range encompassing multiple spectrum blocks, the frequency range encompassing multiple frequency bands;

applying a digital filter to the frequency range including the multiple frequency bands to eliminate at least one unusable spectrum block within the frequency range to create a profile of a single carrier without using carrier aggregation of multiple carriers within the multiple frequency bands;

comparing the profile of the single carrier including the multiple available spectrum blocks to capabilities of a wireless device to enable matching of wireless device capabilities with the multiple available spectrum blocks of the single carrier to determine matching spectrum blocks from the single carrier that is defined without using carrier aggregation of multiple carriers; and

allowing the wireless device to connect to the access node without using carrier aggregation of multiple carriers in compliance with the profile of the single carrier based on the comparison.

19 . The method of claim 18 , further comprising selecting at least one spectrum block of the single carrier based on the comparison.

20 . The method of claim 19 , further comprising sending information identifying the selected spectrum block to the wireless device using a system information block (SIB).
