Turbo HSDPA system
A method of power saving for a wireless transceiver (FIGS. 1 and 2 ) is disclosed. The transceiver has an active power mode ( 504 ) and a reduced power mode ( 510 ). The transceiver is operated in the reduced power mode ( 510 ) and monitors transmissions from a remote wireless transmitter while in the reduced power mode. The transceiver identifies a transmission from the remote wireless transmitter by a transceiver identity included in the transmission (FIG. 6 , UE identification). The transceiver transitions to the active power mode ( 512 ) in response to identifying the transmission.
1. A method of transmitting symbols, comprising the steps of:
forming a plurality of symbols in a packet;
forming pilot and control signals in a first symbol of the plurality of symbols;
excluding all pilot signals and control signals from at least another symbol of the plurality of symbols; and
transmitting the packet.
2. A method as in claim 1 , comprising the step of forming pilot and control signals in a second symbol of the plurality of symbols, wherein the second symbol is adjacent in time to the first symbol.
3. A method as in claim 1 , wherein the step of transmitting comprises transmitting the packet during a transmit time interval (TTI).
4. A method as in claim 1 , wherein each symbol of the plurality of symbols is an orthogonal frequency division multiplex (OFDM) symbol.
5. A method as in claim 1 , wherein a transmit power for the pilot signals is greater than a transmit power for the control signals.
6. A method of communicating with a wireless transceiver, comprising the steps of:
receiving a plurality of symbols in a packet;
receiving pilot and control signals in a first symbol of the plurality of symbols;
receiving data signals excluding all pilot signals and control signals from at least another symbol of the plurality of symbols; and
decoding the packet.
7. A method as in claim 6 , comprising the step of receiving pilot and control signals in a second symbol of the plurality of symbols, wherein the second symbol is adjacent in time to the first symbol.
8. A method as in claim 6 , wherein the step of receiving a plurality of symbols in a packet comprises receiving the packet during a transmit time interval (TTI).
9. A method as in claim 6 , wherein each symbol of the plurality of symbols is an orthogonal frequency division multiplex (OFDM) symbol.
10. A method as in claim 6 , wherein a transmit power for the pilot signals is greater than a transmit power for the control signals.
