Abstract
A base station for use in a 1xEV-DV wireless network comprising: 1) a radio frequency (RF) transceiver for transmitting to mobile stations in voice traffic channels and in at least one packet data channel and 2) a power allocation controller for adjusting the total transmit power allocated to the voice traffic channels and the at least one packet data channel in response to changing conditions in the 1xEV-DV wireless network. The power allocation controller monitors and detects trends in the traffic channel transmit power requirements of the voice-user mobile stations and adjusts the total transmit power according to the detected trend.
Claims20
For use in a 1xEV-DV wireless network capable of communicating with mobile stations in a coverage area of said 1xEV-DV wireless network, a base station comprising:
- a radio frequency (RF) transceiver capable of transmitting to said mobile stations in a plurality of voice traffic channels and in at least one packet data channel;
- and
- a power allocation controller capable of adjusting the total transmit power allocated to said plurality of voice traffic channels and allocated to said at least one packet data channel in response to changing conditions in said 1xEV-DV wireless network.
A wireless network capable of communicating with mobile station in a coverage area of said wireless network according to the 1xEV-DV protocol, said wireless network comprising:
- a plurality of base stations, each of said plurality of base station comprising:
- a radio frequency (RF) transceiver capable of transmitting to said mobile stations in a plurality of voice traffic channels and in at least one packet data channel;
- and
- a power allocation controller capable of adjusting the total transmit power allocated to said plurality of voice traffic channels and allocated to said at least one packet data channel in response to changing conditions in said wireless network.
For use in a 1xEV-DV wireless network capable of communicating with mobile stations in a coverage area of the 1xEV-DV wireless network, a method of operating a base station comprising the steps of:
- transmitting to the mobile stations in a plurality of voice traffic channels and in at least one packet data channel;
- and
- adjusting the total transmit power allocated to the plurality of voice traffic channels and allocated to the at least one packet data channel in response to changing conditions in the 1xEV-DV wireless network.
