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.
Claims14
A wireless device comprising:
- a transceiver;
- and
- a processor, wherein:
- the processor is configured to produce a signal in a time slot of a frame having variable length time slots, the signal having a first portion and a second portion, the first portion being 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,
- wherein the multiplexed first pilot is derived from a pseudo random sequence, the second portion having a pilot sequence and a cyclic prefix, and
- the transceiver is configured to transmit the produced signal in the time slot.

A method comprising:
- producing, by a wireless device, a signal in a time slot of a frame having variable length time slots, the signal having a first portion and a second portion, the first portion being 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,
- wherein the multiplexed first pilot is derived from a pseudo random sequence, the second portion having a pilot sequence and a cyclic prefix;
- and
- transmitting, by the wireless device, the produced signal in the time slot.
1 more element
A wireless device comprising:
- a transceiver;
- and
- a processor, wherein:
- the transceiver is configured to receive a signal in a time slot of a frame having variable length time slots, the signal having a first portion and a second portion, the first portion being 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,
- wherein the multiplexed first pilot is derived from a pseudo random sequence, the second portion having a pilot sequence and a cyclic prefix,
- the processor is configured to process the signal and deriving a first channel estimate using the multiplexed first pilot and a second channel estimate using the pilot sequence, and
- the processor is configured to process the data using the first or the second channel estimate.
