Abstract
Methods and apparatuses are provided for facilitating distributed transmissions among a plurality of access terminals for a transmission sequence. An access point may assign a predecessor transmitter device for each of a plurality of access terminals, and may transmit to each access terminal an instruction to follow a respective preceding transmission by the predecessor transmitter. An access terminal may receive the transmission including the instruction, and may monitor for and detect the preceding transmission. The access terminal may then transmit a transmission after the completion of an interframe space that may follow the detected preceding transmission.
Claims53
An access terminal, comprising:
- a communications interface configured to facilitate wireless communications;
- and
- a processing circuit coupled to the communications interface, the processing circuit configured to:
- receive a transmission via the communications interface, the received transmission including an instruction for the access terminal to follow a preceding transmission during a transmission sequence;
- suspend a backoff-based access to an uplink channel in response to the receipt of the transmission including the instruction for the access terminal to follow the preceding transmission;
- detect the preceding transmission;
- and
- transmit a transmission, via the communications interface, after a duration of an interframe space following the detected preceding transmission.
A method operational on an access terminal, the method comprising:
- receiving a transmission including an instruction for the access terminal to follow a preceding transmission during a transmission sequence;
- suspending a backoff-based access to an uplink channel in response to the receipt of the transmission including the instruction for the access terminal to follow the preceding transmission;
- detecting the preceding transmission;
- and
- transmitting a transmission, via the communications interface, after a duration of an interframe space following the detected preceding transmission.
An access terminal, comprising:
- means for receiving a transmission including an instruction for the access terminal to follow a preceding transmission during a transmission sequence;
- means for suspending a backoff-based access to an uplink channel in response to the receipt of the transmission including the instruction for the access terminal to follow the preceding transmission;
- means for detecting the preceding transmission;
- and
- means for transmitting a transmission after a duration of an interframe space following the detected preceding transmission.
A non-transitory processor-readable medium comprising one or more instructions operational on an access terminal, which, when executed by a processing circuit, causes the processing circuit to:
- receive a transmission including an instruction for the access terminal to follow a preceding transmission during a transmission sequence;
- suspend a backoff-based access to an uplink channel in response to the receipt of the transmission including the instruction for the access terminal to follow the preceding transmission;
- detect the preceding transmission;
- and
- transmit a transmission after a duration of an interframe space following the detected preceding transmission.
An access point, comprising:
- a communications interface configured to facilitate wireless communications;
- and
- a processing circuit coupled to the communications interface, the processing circuit configured to:
- transmit to each access terminal of a plurality of access terminals, via the communications interface, a transmission including an instruction for each access terminal to follow a respective preceding transmission during a transmission sequence;
- suspend a backoff-based access to an uplink channel in response to the receipt of the transmission including the instruction for the access terminal to follow the preceding transmission;
- and
- receive, via the communications interface, a transmission from each of the plurality of access terminals in a sequential order according to the transmission sequence.
A method operational on an access point, the method comprising:
- identifying a sequence for distributed transmissions for a plurality of access terminals;
- transmitting to each access terminal of the plurality of access terminals a transmission including an instruction for each access terminal to follow a respective preceding transmission according to the identified sequence;
- suspending a backoff-based access to an uplink channel in response to the receipt of the transmission including the instruction for the access terminal to follow the preceding transmission;
- and
- receiving a transmission from each of the plurality of access terminals in a sequential order according to the identified sequence.
An access point, comprising:
- means for identifying a sequence for distributed uplink transmissions for a plurality of access terminals;
- means for transmitting to each access terminal of the plurality of access terminals a transmission including an instruction for each access terminal to follow a respective preceding transmission according to the identified sequence;
- means for suspending a backoff-based access to an uplink channel in response to the receipt of the transmission including the instruction for the access terminal to follow the preceding transmission;
- and
- means for receiving a transmission from each of the plurality of access terminals in a sequential order according to the identified sequence.
A non-transitory processor-readable medium comprising one or more instructions operational on an access point, which when executed by a processing circuit, causes the processing circuit to:
- transmit to each access terminal of a plurality of access terminals a transmission including an instruction for each access terminal to follow a respective preceding transmission during a transmission sequence;
- suspend a backoff-based access to an uplink channel in response to the receipt of the transmission including the instruction for the access terminal to follow the preceding transmission;
- and
- receive a transmission from each of the plurality of access terminals in a sequential order according to the transmission sequence.
