Systems and methods for uplink signaling using time-frequency resources

摘要

Methods, base stations and access terminals for uplink signalling are provided. Resource request channel characteristics such as location in time-frequency, sequence, time slot, are assigned to each access terminal to distinguish their resource requests from the resource requests of other access terminals. Access terminals make requests using a resource request on a resource request channel having the assigned characteristics. The base station can then determine which access terminal transmitted 0 the resource request based on the resource request channel characteristics of the resource request channel upon which the resource>request was received. The base station then transmits a response to the request which may for example be a new resource allocation, a default allocation or a renewal of a previous allocation.

1. A method for reception of uplink signaling at a base station from an access terminal of a plurality of access terminals, the method comprising:
at the base station: using an uplink signaling scheme in which:
a) a signaling location allocated for 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; assigning the access terminal a sequence from each of the sets of sequences; and receiving from the access terminal the uplink signaling comprising a transmission on each section of the at least one tile using 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.
