Techniques for conveying identification information in a preamble transmission
Techniques are described for conveying identification information in a preamble transmission. A transmission burst may be generated for transmission over a wireless medium. The transmission burst may include the preamble and a body portion. The preamble may include identification information associated with at least one of a transmitting device or a category of data bring transmitted. The transmission burst may then be transmitted over the wireless medium.
1. A method for wireless communication, comprising:
receiving a transmission burst, the transmission burst comprising a preamble and a body portion, wherein the preamble signals a start of the transmission burst and comprises identification information indicating: a transmitting device, a category of data being transmitted, and whether the transmission is scheduled or non-scheduled;
determining identification information associated with a transmitting device and at least one of a category of data in the body portion or a category of data in another portion of a transmission based at least in part on the preamble of the transmission burst;
determining to ignore a portion of the transmission based at least in part on the identification information; and
ignoring the portion of the transmission based at least in part on determining to ignore the portion of the transmission.
2. The method of claim 1 , wherein the identification information comprises at least one of a cell identification, a group identification associated with a group of cells, a user equipment (UE) identification, a data identification associated with a category of data carried in the body portion of the transmission burst, or a data identification associated with a category of data carried in another portion of a transmission.
3. The method of claim 2 , further comprising:
determining an interference measurement of the transmission burst based at least in part on the identification information; and
transmitting the interference measurement to a serving cell associated with the identification information.
4. The method of claim 2 , further comprising:
determining an interference measurement of the transmission burst based at least in part on the identification information; and
canceling the transmission burst based at least in part on the interference measurement.
5. The method of claim 1 , further comprising:
determining a channel estimation based at least in part on the received preamble.
6. The method of claim 1 , further comprising:
determining the beginning of the body portion of the transmission burst based at least in part on the received preamble.
7. The method of claim 1 , wherein the transmission burst is received over an unlicensed radio frequency spectrum band.
8. The method of claim 1 , wherein the transmission burst comprises a time division duplex (TDD) communication.
9. An apparatus for wireless communication, comprising:
a processor; and
memory coupled to the processor, wherein the processor is configured to:
receive a transmission burst, the transmission burst comprising a preamble and a body portion, wherein the preamble signals a start of the transmission burst and comprises identification information indicating: a transmitting device, a category of data being transmitted, and whether the transmission is scheduled or non-scheduled;
determine identification information associated with a transmitting device and at least one of: a category of data in the body portion or a category of data in another portion of a transmission based at least in part on the preamble of the transmission burst;
determine to ignore a portion of the transmission based at least in part on the identification information; and
ignore the portion of the transmission based at least in part on determining to ignore the portion of the transmission.
10. The apparatus of claim 9 , wherein the identification information comprises at least one of a cell identification, a group identification associated with a group of cells, a user equipment identification, a data identification associated with a category of data carried in the body portion of the transmission burst, or a data identification associated with a category of data carried in another portion of a transmission.
11. The apparatus of claim 10 , wherein the processor is further configured to:
determine an interference measurement of the transmission burst based at least in part on the identification information; and
transmit the interference measurement to a serving cell associated with the identification information.
12. The apparatus of claim 10 , wherein the processor is further configured to:
determine an interference measurement of the transmission burst; and
cancel the transmission burst based at least in part on the interference measurement.
13. The apparatus of claim 9 , wherein the processor is further configured to:
determine a channel estimation based at least in part on the received preamble.
14. The apparatus of claim 9 , wherein the processor is further configured to:
determine the beginning of the body portion of the transmission burst based at least in part on the received preamble.
15. The apparatus of claim 9 , wherein the transmission burst comprises a time division duplex (TDD) communication.
