Abstract
Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to techniques for accurately determining a number of data symbols in a data packet. The techniques provided herein may allow a receiving terminal to correct number of symbol calculations based on such ambiguous length field values.
Claims46
A method for wireless communications, comprising:
- generating a data packet comprising one or more data symbols;
- providing, in a preamble field of the data packet, a length field used to calculate a number of data symbols by a receiving entity and a correction field that indicates whether or not the calculated number of data symbols should be corrected, wherein the number of data symbols is based on the length field and a number of training fields;
- and
- transmitting the data packet.
A method for wireless communications, comprising:
- receiving a data packet comprising one or more data symbols;
- extracting a length field and a correction field from the data packet;
- and
- calculating a number of data symbols in the packet, based on the length field and a number of training fields.
An apparatus for wireless communications, comprising:
- means for generating a data packet comprising one or more data symbols;
- means for providing, in a preamble field of the data packet, a length field used to calculate a number of data symbols by a receiving entity and a correction field that indicates whether or not the calculated number of data symbols should be corrected, wherein the number of data symbols is based on the length field and a number of training fields;
- and
- means for transmitting the data packet.
An apparatus for wireless communications, comprising:
- means for receiving a data packet comprising one or more data symbols;
- means for extracting a length field and a correction field from the data packet;
- and
- means for calculating a number of data symbols in the packet, based on the length field and a number of training fields.
An apparatus for wireless communications, comprising:
- at least one processor configured to:
- generate a data packet comprising one or more data symbols,
- provide, in a preamble field of the data packet, a length field used to calculate a number of data symbols by a receiving entity and a correction field that indicates whether or not the calculated number of data symbols should be corrected, wherein the number of data symbols is based on the length field and a number of training fields, and transmit the data packet;
- and
- a memory coupled with the at least one processor.
An apparatus for wireless communications, comprising:
- at least one processor configured to receive a data packet comprising one or more data symbols, extract a length field and a correction field from the data packet, and calculate a number of data symbols in the packet, based on the length field and a number of training fields;
- and
- a memory coupled with the at least one processor.
A computer-program product comprising a non-transitory computer-readable medium having instructions stored thereon, the instructions executable by one or more processors for:
- generating a data packet comprising one or more data symbols;
- providing, in a preamble field of the data packet, a length field used to calculate a number of data symbols by a receiving entity and a correction field that indicates whether or not the calculated number of data symbols should be corrected, wherein the number of data symbols is based on the length field and a number of training fields;
- and
- transmitting the data packet.
