Efficient usage of hardware processing resources
View Patent ↗A wireless communication device monitors a radio frequency (RF) resource for a signal from a remote terminal. The wireless communications device detects the absence of the signal in the monitored RF resource. If the signal is not present in the RF resource, the wireless communications device reallocates processing resources reserved to process the signal to process data from another remote terminal.
1. A method comprising:
allocating processing resources to process an RF signal burst from a remote terminal on an uplink transmission carrier, the RF signal burst comprising a traffic channel burst from the remote terminal;
determining whether a portion of the processing resources are available to process other data; and
reallocating the portion of processing resources to process the other data when the portion of processing resources are determined to be available, wherein reallocating the portion of processing resources comprises reallocating the portion of processing resources into two or more sub-portions of processing resources including at least a first sub-portion of processing resources to process a random access burst from a second remote terminal and a second sub-portion of processing resources to process the other data.
2. The method of claim 1 , wherein determining whether the portion of processing resources are available to process other data comprises determining whether a radio frequency (“RF”) signal from the remote terminal is absent in an RF resource.
3. The method of claim 2 , wherein determining whether the RF signal from the remote terminal is absent in the RF resource comprises determining whether the traffic channel burst is absent in the RF resource.
4. The method of claim 3 , wherein determining whether the RF signal is absent from the RF resource comprises monitoring an uplink timeslot on a time division multiple access (TDMA) channel for the traffic channel burst from the remote terminal.
5. The method of claim 3 , wherein determining whether the RF signal is absent from the RF resource comprises monitoring a global system for mobile communications (GSM) channel for the traffic channel burst from the remote terminal.
6. The method of claim 3 , wherein determining whether the RF signal is absent from the RF resource comprises monitoring a code division multiple access (CDMA) channel for the traffic channel burst from the remote terminal.
7. The method of claim 3 , wherein determining whether the RF signal is absent from the RF resource comprises monitoring a particular uplink frequency band on a frequency division multiple access (FDMA) channel for the traffic channel burst from the remote terminal.
8. The method of claim 1 , further comprising:
allocating the second sub-portion of processing resources to process a stream request message from a third remote terminal.
9. The method of claim 1 , further comprising:
allocating the second sub-portion of processing resources to process a random access burst from a third remote terminal.
10. The method of claim 1 , wherein the processing resources allocated to process the RF signal burst from the remote terminal are, at least in part, processing resources allocated to decode the RF signal burst.
11. The method of claim 1 , wherein the processing resources allocated to process the RF signal burst from the remote terminal are, at least in part, processing resources allocated to construct a second RF signal burst to be transmitted to the remote terminal on a downlink transmission carrier in response to the RF signal burst from the remote terminal on the uplink transmission carrier.
12. The method of claim 1 , wherein the processing resources comprise processing resources from two or more digital signal processors.
13. The method of claim 1 , further comprising transmitting a second RF signal burst to a second remote terminal to inform the second remote terminal that a page burst will be subsequently transmitted.
