Abstract

Computer readable media, methods, and apparatus for resource block identification (RBIDs) for neighbor station resource requests are disclosed. An apparatus of a station is disclosed. The apparatus may include a memory, and processing circuitry coupled to the memory. The processing circuitry may be configured to decode a neighbor report comprising one or more RBIDs from a first access point. Each RBID may indicate a frequency resource allocation to transmit one bit of information to a second access point. The processing circuitry may be further configured to respond to decoding a poll trigger from the second access point, by encoding a response to the poll trigger in accordance with the corresponding frequency resource allocation indicated by one of the one or more RBIDs. The processing circuitry may be further configured to configure the station to transmit the response to the second access point in accordance orthogonal frequency division multiple access (OFDMA).
