System and method for utilizing overlapping component carriers
A new radio base station establishes a first and a second component. The first and second component carrier overlap each other. The base station transmits first synchronization signal blocks on the first component carrier. The base station transmits second synchronization signal blocks on the second component carrier interleaved in time with the first synchronization signal blocks.
1. A method comprising:
establishing, with a base station, a first component carrier having a first frequency band;
establishing, with the base station, a second component carrier having a second frequency band that overlaps the first frequency band;
transmitting, from the base station, first synchronization signal blocks in the first frequency band;
transmitting, from the base station, second synchronization signal blocks in the second frequency band and interleaved in time with the first synchronization signal blocks; and
transmitting a physical random-access channel exclusively on frequencies corresponding to an overlap between the first frequency band and the second frequency band.
2. The method of claim 1 , further comprising:
transmitting a first control resource set in the first frequency band; and
transmitting a second control resource set in the second frequency band.
3. The method of claim 1 , further comprising transmitting system information blocks from the base station exclusively on frequencies corresponding to an overlap between the first and second frequency bands.
4. The method of claim 1 , further comprising:
transmitting a first physical random-access channel in the first frequency band; and
transmitting a second physical random-access channel in the second frequency band.
5. The method of claim 4 , wherein the first physical random-access channel is not transmitted at frequencies that overlap with the second physical random-access channel.
6. The method of claim 1 , further comprising establishing a transmission passband with a transmission filter of the base station, wherein the transmission passband ensures that the base station only transmits signals with an allotted bandwidth of the base station.
7. The method of claim 6 , further comprising establishing a receiving passband with a receiving filter of the base station, wherein the receiving passband ensures that the base station only receives signals within the allotted bandwidth of the base station.
8. The method of claim 1 , wherein the base station is a 5G new radio base station.
9. The method of claim 1 , wherein the overlapping first and second component carriers comply with 3GPP standards.
10. A base station, comprising:
a transceiver configured to transmit and receive signals;
one or more processors coupled to the transceiver; and
one or computer readable media including instructions that, when executed by the one or more processors, perform a process including:
establishing, at least in part with the transceiver, a first component carrier having a first frequency band;
establishing, at least in part with the transceiver, a second component carrier having a second frequency band that overlaps with the first frequency band;
transmitting, from the base station, first synchronization signal blocks in the first frequency band;
transmitting, from the base station, second synchronization signal blocks in the second frequency band and interleaved in time with the first synchronization signal blocks; and
transmitting a physical random-access channel exclusively on frequencies corresponding to an overlap between the first frequency band and the second frequency band.
11. The base station of claim 10 , further comprising a transmission filter that establishes a transmission passband that ensures that the transceiver only transmits signals within an allotted bandwidth.
12. The base station of claim 10 , further comprising a receiving filter configured to establish a receiving passband that ensures that the transceiver only receives signals within an allotted bandwidth.
13. The base station of claim 12 , wherein first and second component carriers each include a plurality of physical resource blocks.
14. The base station of claim 10 , wherein the process further comprises:
transmitting a first control resource set in the first frequency band; and
transmitting a second control resource set in the second frequency band.
15. The base station of claim 10 , wherein the process further comprises:
transmitting system information blocks from the base station exclusively on frequencies corresponding to an overlap between the first and second frequency bands.
16. The base station of claim 10 , wherein the process further comprises:
transmitting a first physical random-access channel in the first frequency band; and
transmitting a second physical random-access channel in the second frequency band.
17. The base station of claim 16 , wherein the first physical random-access channel is not transmitted at frequencies that overlap with the second physical random-access channel.
18. The base station of claim 10 , wherein the process further comprises establishing a transmission passband with a transmission filter of the base station, wherein the transmission passband ensures that the base station only transmits signals with an allotted bandwidth of the base station.
19. The base station of claim 10 , wherein the process further comprises establishing a receiving passband with a receiving filter of the base station, wherein the receiving passband ensures that the base station only receives signals within the allotted bandwidth of the base station.
