Abstract
A wireless device is configured to produce a signal in a time slot, the signal having a first portion and a second portion. Wherein, the first portion being a first in time in the time slot and the second portion being last in time in the time slot. Further, the first portion having data and a multiplexed first pilot and the second portion having a pilot sequence and a cyclic prefix. The wireless device transmits the produced signal in the time slot.
Claims20
A wireless device comprising:
- a transceiver;
- and
- a processor, wherein:
- the transceiver and the processor are configured to:
- produce a signal in a time slot, the signal having a first portion and a second portion, the first portion being a first in time in the time slot and the second portion being last in time in the time slot, the first portion having data and a multiplexed first pilot, the second portion having a pilot sequence and a cyclic prefix, and
- transmit the produced signal in the time slot.

A method comprising:
- producing, by a wireless device, a signal in a time slot, the signal having a first portion and a second portion, the first portion being a first in time in the time slot and the second portion being last in time in the time slot, the first portion having data and a multiplexed first pilot, the second portion having a pilot sequence and a cyclic prefix;
- and
- transmitting, by the wireless device, the produced signal in the time slot.
A wireless device comprising:
- a transceiver;
- and
- a processor, wherein:
- the transceiver and the processor are configured to:
- receive a signal in a time slot, the signal having a first portion and a second portion, the first portion being a first in time in the time slot and the second portion being last in time in the time slot, the first portion having data and a multiplexed first pilot, the second portion having a pilot sequence and a cyclic prefix,
- processing the signal and deriving a first channel estimate using the first pilot and a second channel estimate using the pilot sequence, and
- processing the data using the first or the second channel estimate.
