Systems and methods for uplink signaling using time-frequency resources

A base station configured for receiving uplink signaling from an access terminal of a plurality of access terminals, the base station comprising:

• a transceiver for performing wireless communication with the plurality of access terminals;
• processing hardware coupled to the transceiver, wherein the processing hardware is configured to cause the base station to:
• use an uplink signaling scheme in which:
• a) a signaling location allocated for the uplink signaling comprises at least one tile comprising a contiguous set of time-frequency resources within a transmission resource;
• b) each tile of the at least one tile comprises at least two sections;
• c) for each of the at least two sections of each tile, a respective set of sequences for transmission on that section of the corresponding tile is allocated;
• assign the access terminal a sequence from each of the sets of sequences;
• and
• receive from the access terminal the uplink signaling comprising a transmission on each section of the at least one tile using the corresponding sequences assigned to the access terminal for each section of the at least one tile,
• wherein a time-frequency location of the at least one tile in the transmission resource and/or the sequence from each of the sets of sequences is used by the base station to identify from which access terminal the transmission originates.

A non-transitory, computer accessible memory medium storing program instructions for receiving uplink signaling from an access terminal of a plurality of access terminals by a base station, wherein the program instructions are executable by one or more processors of the base station to cause the base station to:

• use an uplink signaling scheme in which:
• a) a signaling location allocated for the uplink signaling comprises at least one tile comprising a contiguous set of time-frequency resources within a transmission resource;
• b) each tile of the at least one tile comprises at least two sections;
• c) for each of the at least two sections of each tile, a respective set of sequences for transmission on that section of the corresponding tile is allocated;
• assign the access terminal a sequence from each of the sets of sequences;
• and
• receive from the access terminal the uplink signaling comprising a transmission on each section of the at least one tile using the corresponding sequences assigned to the access terminal for each section of the at least one tile,
• wherein a time-frequency location of the at least one tile in the transmission resource and/or the sequence from each of the sets of sequences is used by the base station to identify from which access terminal the transmission originates.

A method for transmitting uplink signaling from a wireless device of a plurality of wireless devices to a base station, the method comprising:
