Abstract
A method for simultaneously transmitting packets to one or more users in a wireless communication system includes: generating the packets which include length information and are to be transmitted to the one or more users; and simultaneously transmitting the generated packets to the one or more users. The length information includes information representing a unit of the length information and information representing lengths of the packets according to the unit.
Claims6
A method for transmitting data in a wireless communication system, the method comprising:
- generating, by the transmitter, a data field;
- and
- transmitting, by the transmitter, a data packet including the data field,
- wherein generating the data field comprises:
- generating a data unit comprising a plurality of Aggregate-Medium Access Control Protocol Data Unit (A-MPDU) subframes;
- adding a Medium Access Control (MAC) pad to the data unit to generate a padded unit;
- and
- adding a physical pad to the padded unit to generate the data field,
- wherein the MAC pad includes a first pad, a second pad and a third pad, the first pad having a length of 0 to 3 bytes, the second pad having a length of a multiple of 4 bytes, the third pad having a length of 0 to 3 bytes,
- wherein the physical pad has a length of 0 to 7 bits.
An apparatus configured for transmitting data in a wireless communication system, the method comprising:
- a packet generation unit configured to generate a data field;
- and
- a packet transmission unit configured to transmit a data packet including the data field,
- wherein the packet generation unit is configured to generate the data field by:
- generating a data unit comprising a plurality of Aggregate-Medium Access Control Protocol Data Unit (A-MPDU) subframes;
- adding a Medium Access Control (MAC) pad to the data unit to generate a padded unit;
- and
- adding a physical pad to the padded unit to generate the data field,
- wherein the MAC pad includes a first pad, a second pad and a third pad, the first pad having a length of 0 to 3 bytes, the second pad having a length of a multiple of 4 bytes, the third pad having a length of 0 to 3 bytes,
- wherein the physical pad has a length of 0 to 7 bits.
