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.
Claims22
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, and the transmission bandwidth having a set of sub-bands;
- identify preamble information to be transmitted to a plurality of receivers, the preamble information including common preamble information for the plurality of receivers and dedicated information for particular receivers of the plurality of receivers;
- determine second WLAN preamble portion resource allocations for the plurality of receivers to receive the dedicated information and data portion resource allocations for the plurality of receivers to receive data;
- and
- transmit an indication of the second WLAN preamble portion resource allocations and data portion resource allocations in the common preamble information.
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, and the transmission bandwidth having a set of sub-bands;
- identifying preamble information to be transmitted to a plurality of receivers, the preamble information including common preamble information for the plurality of receivers and dedicated information for particular receivers of the plurality of receivers;
- determining second WLAN preamble portion resource allocations for the plurality of receivers to receive the dedicated information and data portion resource allocations for the plurality of receivers to receive data;
- and
- transmitting an indication of the second WLAN preamble portion resource allocations and data portion resource allocations in the common preamble information.
An apparatus for wireless communication, comprising:
- means for identifying a transmission bandwidth for a wireless frame, the wireless frame including a legacy wireless local area network (WLAN) preamble portion, a second WLAN preamble portion, and a data portion, and the transmission bandwidth having a set of sub-bands;
- means for identifying preamble information to be transmitted to a plurality of receivers, the preamble information including common preamble information for the plurality of receivers and dedicated information for particular receivers of the plurality of receivers;
- means for determining second WLAN preamble portion resource allocations for the plurality of receivers to receive the dedicated information and data portion resource allocations for the plurality of receivers to receive data;
- and
- means for transmitting an indication of the second WLAN preamble portion resource allocations and data portion resource allocations in the common preamble information.
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, and the transmission bandwidth having a set of sub-bands;
- identify preamble information to be transmitted to a plurality of receivers, the preamble information including common preamble information for the plurality of receivers and dedicated information for particular receivers of the plurality of receivers;
- determine second WLAN preamble portion resource allocations for the plurality of receivers to receive the dedicated information and data portion resource allocations for the plurality of receivers to receive data;
- and
- transmit an indication of the second WLAN preamble portion resource allocations and data portion resource allocations in the common preamble information.
