Abstract
The embodiments of the present disclosure disclose a method for uplink multiuser data transmission and a system for uplink multiuser multiple input multiple output. The method includes: sending, by an access point AP, indication information to at least two stations STAs, wherein the indication information is used for indicating that the at least two STAs perform an uplink multiuser data transmission; receiving, by the AP, uplink data sent by the at least two STAs through channels from the at least two STAs to the AP, respectively; and demodulating, by the AP, the uplink data sent by the at least two STAs using receiving beams corresponding to pre-estimated channels from the at least two STAs to the AP, respectively.
Claims16
An apparatus comprising:
- a processor coupled to a memory, and
- the memory having processor-executable instructions stored thereon, wherein the instructions are executed by the processor to cause the apparatus to perform operations including:
- receiving one or more second requests for transmitting data from one or more of multiple stations,
- wherein each of the one or more second requests comprises a first sequence identifying a first station among the multiple stations, and a second sequence identifying a second station among the multiple stations, and
- wherein the first sequence is a first long training field (LTF) section which identifies the first station, the second sequence is a second LTF section which identifies the second station;
- receiving a buffer message from each of the one or more multiple stations, wherein the buffer message indicates an amount of to-be-sent data at an associated station;
- selecting buffer messages whose indication of to-be-sent data reaches a threshold, wherein reaching the threshold indicates a station associated with the buffer message needs to perform an uplink data transmission;
- and
- determining one or more stations from the one or more multiple stations which have sent the second requests for uplink data transmission according to (i) a sequence in one of the one or more second requests, and (ii) the selected buffer messages.
An apparatus comprising:
- a processor, coupled to a memory, and
- the memory having processor-executable instructions stored thereon, wherein the instructions are executed by the processor to cause the apparatus perform operations including:
- sending a second request to an access point for uplink data transmission,
- wherein the second request comprises a sequence identifying the apparatus as a station among multiple stations sending second requests for uplink data transmission, and
- wherein the sequence identifying the apparatus is a long training field (LTF) section;
- sending a buffer message to the access point, wherein the buffer message indicates an amount of to-be-sent data at the apparatus;
- and
- performing the uplink data transmission with the access point in response to selection of the apparatus for the uplink data transmission based on the amount of to-be-sent data indicated by the buffer message.
A non-transitory computer readable storage medium comprising a program which is executed by a processor of a computer and causes the computer to:
- receive one or more second requests for transmitting data from one or more of multiple stations,
- wherein each of the one or more second requests comprises a first sequence identifying a first station among the multiple stations, and a second sequence identifying a second station among the multiple stations, and
- wherein the first sequence is a first long training field (LTF) section which identifies the first station, the second sequence is a second LTF section which identifies the second station;
- receive a buffer message from each of the one or more multiple stations, wherein the buffer message indicates an amount of to-be-sent data at an associated station;
- select buffer messages whose indication of to-be-sent data reaches a threshold, wherein reaching the threshold indicates a station associated with the buffer message needs to perform an uplink data transmission;
- and
- determine one or more stations from the one or more multiple stations which have sent the second requests for uplink data transmission according to (i) a sequence in one of the one or more second requests, and (ii) the selected buffer messages.
A non-transitory computer readable storage medium comprising a program which is executed by a processor of a computer and causes the computer to:
- send a second request to an access point for uplink data transmission,
- wherein the second request comprises a sequence identifying a first station as a station among multiple stations sending second requests for uplink data transmission, and
- wherein the sequence identifying the apparatus is a long training field (LTF) section;
- send a buffer message to the access point, wherein the buffer message indicates an amount of to-be-sent data at the first station;
- and
- perform the uplink data transmission with the access point in response to selection of the first station for the uplink data transmission based on the amount of to-be-sent data indicated by the buffer message.
