Abstract
Techniques are described for wireless communication. One or more wireless local area network (WLAN) preamble portions may span multiple 20 MHz frequency bands, and may be duplicated across a transmission bandwidth. WLAN preamble portions may include common portions for multiple receivers as well as dedicated portions for particular receivers, and common portions may be transmitted in a primary frequency band in some examples. Some techniques provide that WLAN preamble portions may be encoded using different sized code blocks. Various aspects of the disclosure also provide for signaling of resource allocations of WLAN wireless frames.

An apparatus for wireless communication, comprising:
- a memory that stores instructions;
- and
- a processor coupled with the memory, wherein the processor and the memory are configured to:
- identify a transmission bandwidth for a wireless frame, the wireless frame including a first wireless local area network (WLAN) preamble portion, a second WLAN preamble portion, and a data portion, wherein the transmission bandwidth comprises a set of sub-bands;
- identify a first subset of the set of sub-bands within the transmission bandwidth for transmission of the second WLAN preamble portion, the second WLAN preamble portion spanning two or more sub-bands within the first subset of sub-bands, wherein information of the second WLAN preamble within a first sub-band of the two or more sub-bands is different than at least some of the information of the second WLAN preamble within another sub-band of the two or more sub-bands;
- identify a second subset of the set of sub-bands within the transmission bandwidth for transmission of a redundant version of the second WLAN preamble portion;
- and
- transmit the wireless frame to one or more receivers.
A method for wireless communication by a wireless device, comprising:
- identifying a transmission bandwidth for a wireless frame, the wireless frame including a first wireless local area network (WLAN) preamble portion, a second WLAN preamble portion, and a data portion, wherein the transmission bandwidth comprises a set of sub-bands;
- identifying a first subset of the set of sub-bands within the transmission bandwidth for transmission of the second WLAN preamble portion, the second WLAN preamble portion spanning two or more sub-bands within the first subset of sub-bands, wherein information of the second WLAN preamble within a first sub-band of the two or more sub-bands is different than at least some of the information of the second WLAN preamble within another sub-band of the two or more sub-bands;
- identifying a second subset of the set of sub-bands within the transmission bandwidth for transmission of a redundant version of the second WLAN preamble portion;
- and
- transmitting the wireless frame to one or more receivers.
An apparatus for wireless communication, comprising:
- means for identifying a transmission bandwidth for a wireless frame, the wireless frame including a first wireless local area network (WLAN) preamble portion, a second WLAN preamble portion, and a data portion, wherein the transmission bandwidth comprises a set of sub-bands;
- means for identifying a first subset of the set of sub-bands within the transmission bandwidth for transmission of the second WLAN preamble portion, the second WLAN preamble portion spanning two or more sub-bands within the first subset of sub-bands, wherein information of the second WLAN preamble within a first sub-band of the two or more sub-bands is different than at least some of the information of the second WLAN preamble within another sub-band of the two or more sub-bands;
- means for identifying a second subset of the set of sub-bands within the transmission bandwidth for transmission of a redundant version of the second WLAN preamble portion;
- and
- means for transmitting the wireless frame to one or more receivers.
A non-transitory computer-readable medium storing code for wireless communication, the code comprising instructions executable to:
- identify a transmission bandwidth for a wireless frame, the wireless frame including a first wireless local area network (WLAN) preamble portion, a second WLAN preamble portion, and a data portion, wherein the transmission bandwidth comprises a set of sub-bands;
- identify a first subset of the set of sub-bands within the transmission bandwidth for transmission of the second WLAN preamble portion, the second WLAN preamble portion spanning two or more sub-bands within the first subset of sub-bands, wherein information of the second WLAN preamble within a first sub-band of the two or more sub-bands is different than at least some of the information of the second WLAN preamble within another sub-band of the two or more sub-bands;
- identify a second subset of the set of sub-bands within the transmission bandwidth for transmission of a redundant version of the second WLAN preamble portion;
- and
- transmit the wireless frame to one or more receivers.
