Abstract
A wireless transceiver decodes a receive signal to extract data contained in the receive signal. A processing block contained in the wireless transceiver then initiates a power-ON of the transmit radio portions of the transceiver prior to initiating a power-OFF of the receive radio portions. The technique enables the transceiver to meet timing requirements when operating in environments that require an acknowledgement to be sent in response to receipt of data.
Claims20
A method implemented in a wireless transceiver, said wireless transceiver containing a first set of components in a receiver portion, and a second set of components in a transmitter portion, said method comprising:
- receiving a receive signal from a wireless medium;
- decoding said receive signal to extract data contained in said receive signal;
- and
- after said receiving, initiating a powering-ON of said second set of components prior to initiating a powering-OFF of said first set of components.
A wireless transceiver comprising:
- a transmit block;
- a receive block;
- and
- a first processing block to control provision of power to a radio portion of said transmit block and a radio portion of said receive block,
- wherein said receive block receives a receive signal from a wireless medium and decodes said receive signal to extract data contained in said receive signal, and
- wherein said first processing block initiates, after said receive block extracts said data, a power-ON of components in said radio portion of said transmit block prior to initiating a power-OFF of components in said radio portion of said receive block.
A machine readable medium storing one or more sequences of instructions in a wireless transceiver containing a first set of components in a receiver portion, and a second set of components in a transmitter portion, wherein execution of said one or more sequences of instructions by one or more processors contained in said wireless transceiver causes said wireless transceiver to perform the actions of:
- receiving a receive signal from a wireless medium;
- decoding said receive signal to extract data contained in said receive signal;
- and
- after said receiving, initiating a powering-ON of said second set of components prior to powering-OFF of said first set of components.
