Apparatus for allocating transmission period in a wireless communication system
First Claim
1. A station (STA) apparatus for receiving an allocated transmission period in a transmission frame period in a wireless network system, said transmission frame period having a preset duration, the apparatus comprising:
- a processor for analyzing a power save multi-poll (PSMP) frame providing by an access point (AP) a downlink period and an initial uplink period, and if the initial uplink period provided by the PSMP frame is insufficient to transmit queued data, generating a data unit including a part of the queued data and a resource request message requesting an allocation of additional resources for remaining queued data;
a transceiver for receiving the PSMP frame from the AP, delivering the PSMP frame to the processor, transmitting the data unit to the AP in the initial uplink period and receiving in the transmission frame period a sub PSMP frame providing by the AP an additional uplink period, the sub PSMP frame being transmitted by the AP after all of the periods provided by the PSMP frame, and transmitting at least part of the remaining queued data to the AP in the additional uplink period provided by the sub PSMP frame.

Abstract
An apparatus is provided for efficiently allocating a transmission period in a wireless network system. An access point (AP) transmits a PSMP frame indicating a downlink period provided to each station (STA) and a minimum amount of an uplink period allocated to each STA, and at least one sub PSMP frame indicating an uplink period additionally provided for an STA that transmitted a resource request message for remaining queued data in the uplink period indicated by the PSMP frame. If the uplink period indicated by the PSMP frame is insufficient to transmit the queued data, the STA transmits a data unit including a part of the queued data and a resource request message for the remaining queued data in the uplink period. After transmitting the resource request message, the STA receives the sub PSMP frame after the full period indicated by the sub PSMP frame, and transmits the remaining queued data to the AP in the uplink period indicted by the sub PSMP frame.
