Providing control signalling over different radio access technologies (RATs)
View Patent ↗A wireless multimedia point-to-multipoint network using different radio access technologies (RATs) is disclosed. Paired cellular spectrum may be used by the RATs. Controlling signaling and traffic may be sent using different RATs. Channel setup information may be provided by different RATs.
1. A method performed by a wireless network, the method comprising:
transmitting, by the wireless network, first information using a first radio access technology (RAT) of a first frequency, wherein the first frequency is part of a first paired spectrum;
transmitting, by the wireless network, second information using a second RAT of a second frequency, wherein the second frequency is part of a second paired spectrum;
sending, by the wireless network, downlink control information over the first RAT;
sending, by the wireless network, downlink data over the second RAT for a multimedia multicast service, wherein the downlink data is communicated based on the downlink control information and channel setup information sent over the first RAT; and
wherein the downlink control information over the first RAT and the downlink data over the second RAT are sent substantially simultaneously.
2. The method of claim 1 , wherein the first RAT and the second RAT utilize W-CDMA.
3. The method of claim 1 , wherein the channel setup information comprises radio access bearer setup information.
4. The method of claim 1 further comprising:
handing over, by the wireless network, a user equipment (UE) from the first RAT to the second RAT.
5. The method of claim 1 , wherein the first paired spectrum and the second paired spectrum are part of a same spectrum.
6. A network device comprising:
a transmitter configured to transmit first information with utilization of a first radio access technology (RAT) of a first frequency, wherein the first frequency is part of a first paired spectrum;
the transmitter further configured to transmit second information with utilization of a second RAT of a second frequency, wherein the second frequency is part of a second paired spectrum;
circuitry configured to send downlink control information over the first RAT;
circuitry configured to send downlink data over the second RAT for a multimedia multicast service, wherein the downlink data is communicated based on the downlink control information and channel setup information sent over the first RAT; and
wherein the downlink control information over the first RAT and the downlink data over the second RAT are sent substantially simultaneously.
7. The network device of claim 6 , wherein the first RAT and the second RAT utilize W-CDMA.
8. The network device of claim 6 , wherein the channel setup information comprises radio access bearer setup information.
9. The network device of claim 6 further comprising:
circuitry configured to handover a user equipment (UE) from the first RAT to the second RAT.
10. The network device of claim 6 , wherein the first paired spectrum and the second paired spectrum are part of a same spectrum.
11. A user equipment (UE) comprising:
a receiver configured to receive first information over a first radio access technology (RAT) of a first frequency, wherein the first frequency is part of a first paired spectrum;
the receiver further configured to receive second information over a second RAT of a second frequency, wherein the second frequency is part of a second paired spectrum;
the receiver further configured to receive downlink control information over the first RAT;
a processor configured to receive downlink data over the second RAT for a multimedia multicast service, wherein the downlink data is communicated based on the downlink control information and channel setup information received over the first RAT; and
wherein the downlink control information over the first RAT and the downlink data over the second RAT are received substantially simultaneously.
12. The UE of claim 11 , wherein the first RAT and the second RAT utilize W-CDMA.
13. The UE of claim 11 , wherein the channel setup information comprises radio access bearer setup information.
14. The UE of claim 11 further comprising:
the processor configured to handover from the first RAT to the second RAT.
15. The UE of claim 11 , wherein the first paired spectrum and the second paired spectrum are part of a same spectrum.
16. A method performed by a user equipment (UE), the method comprising:
receiving, by the UE, first information over a first radio access technology (RAT) of a first frequency, wherein the first frequency is part of a first paired spectrum;
receiving, by the UE, second information over a second RAT of a second frequency, wherein the second frequency is part of a second paired spectrum;
receiving, by the UE, downlink control information over the first RAT;
receiving, by the UE, downlink data over the second RAT for a multimedia multicast service, wherein the downlink data is communicated based on the downlink control information and channel setup information received over the first RAT; and
wherein the downlink control information over the first RAT and the downlink data over the second RAT are received substantially simultaneously.
17. The method of claim 16 , wherein the first RAT and the second RAT utilize W-CDMA.
18. The method of claim 16 , wherein the channel setup information comprises radio access bearer setup information.
19. The method of claim 16 further comprising:
handing over, by the UE, from the first RAT to the second RAT.
20. The method of claim 16 , wherein the first paired spectrum and the second paired spectrum are part of a same spectrum.
