Abstract:
1. An access point (AP) apparatus for allocating a transmission period in a frame period in a wireless network system, the apparatus comprising: a processor which generates a first power save multi-poll (PSMP) frame allocating a downlink period and an uplink period to a station (STA), wherein: the uplink period is provided for receiving queued data of the STA, and after the downlink and uplink periods, and in response to a resource request message from the STA requesting allocation of an additional resource, the processor generates a subsequent PSMP frame allocating an additional uplink period to the STA, wherein the subsequent PSMP frame is an additional PSMP frame following the first PSMP frame; and a transceiver which transmits to the STA the subsequent PSMP after the downlink and uplink periods and receives at least a portion of remaining queued data from the STA during the additional uplink period.
