Wireless communication system for allocating transmission period
First Claim
1. A wireless network system, comprising:
- an access point (AP) to transmit a first power save multi-poll (PSMP) frame allocating a downlink period and an uplink period and transmit a subsequent PSMP frame allocating an additional uplink period after the downlink and uplink periods, wherein the subsequent PSMP is an additional PSMP frame to follow the first PSMP frame; and
a station (STA) to transmit to the AP during the uplink period a part of the queued data and a resource request message requesting allocation of an additional resource for at least a portion of remaining queued data of the STA, if the uplink period is insufficient for transmitting the queued data, and to receive from the AP the subsequent PSMP frame allocating the additional uplink period and transmit the at least a portion of remaining queued data to the AP during the additional uplink period.

Abstract
A system 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.
