Maintenance of channel usage in a wireless communication system
View Patent ↗Data is accessed from a network via a wireless communication link. A determination is made as to whether payload data has been received from a subscriber's terminal. If so, then a request is sent for a first set of traffic channels, and the payload data is transmitted over the first set of traffic channels.
1. A wireless code division multiple access (CDMA) device comprising:
a processing device configured, on a condition that payload data associated with a channel is present, to determine a size of the payload data associated with the channel;
wherein the processing device is further configured, on the condition that the payload data associated with the channel is present, to transmit information to a base station;
wherein the processing device is further configured to receive a grant in response to the transmitted information;
wherein the processing device is further configured in response to the grant to transmit the payload data over at least one CDMA channel; and
wherein on a condition that the processing device has no payload data to transmit, the processing device is further configured to transmit only a control channel signal to the base station.
2. The wireless CDMA device of claim 1 wherein a number of CDMA channels that the payload data is transmitted over is derived from at least the grant.
3. The wireless CDMA device of claim 1 wherein the payload data is transmitted over a plurality of CDMA channels and a portion of the payload data is transmitted over each channel.
4. The wireless CDMA device of claim 3 wherein a number of the plurality of CDMA channels that the payload data is transmitted over is derived from at least the grant.
5. The wireless CDMA device of claim 1 wherein the processing device is further configured to transition from an idle to an active mode on a condition that the payload data is received.
6. The wireless CDMA device of claim 1 wherein the control channel transmission is used for uplink timing synchronization.
7. The wireless CDMA device of claim 6 wherein the control channel transmission has a lower bandwidth than the control channel transmission when transmitted with a CDMA channel carrying payload data.
8. A method implemented in a wireless code division multiple access (CDMA) device, the method comprising:
on a condition that payload data associated with a channel is present, determining a size of the payload data associated with the channel;
on the condition that the payload data associated with the channel is present, transmitting information to a base station;
receiving a grant in response to the transmitted information;
wherein the processing device is further configured in response to the grant transmitting the payload data over at least one CDMA channel in response to the grant; and
transmitting only a control channel signal to the base station on a condition that a processing device has no payload data to transmit.
9. The method of claim 8 wherein a number of CDMA channels that the payload data is transmitted over is derived from at least the grant.
10. The method of claim 8 wherein the payload data is transmitted over a plurality of CDMA channels and a portion of the payload data is transmitted over each channel.
11. The method of claim 10 wherein a number of the plurality of CDMA channels that the payload data is transmitted over is derived from at least the grant.
12. The method of claim 8 further comprising transitioning from an idle to an active mode on a condition that the payload data is received.
13. The method of claim 8 wherein the control channel transmission is used for uplink timing synchronization.
14. The method of claim 13 wherein the control channel transmission has a lower bandwidth than the control channel transmission when transmitted with a CDMA channel carrying payload data.
