Apparatus for allocating transmission period in a wireless communication system
First Claim
1. An access point (AP) apparatus for allocating a transmission period in a transmission frame period having a preset duration in a wireless network system in a wireless network system, the apparatus comprising:
- a processor for generating a power save multi-poll (PSMP) frame providing at least one of an initial downlink period and an initial uplink period allocated to a station (STA), and generating a sub PSMP frame providing an additional period for retransmitting at least one of downlink data and uplink data; and
a transceiver for transmitting the PSMP frame to the STA, receiving data by the STA in the initial downlink period, transmitting data by the STA in the initial uplink period, and after the initial downlink period and the initial uplink period, transmitting in the transmission frame period the sub PSMP frame, and retransmitting in the transmission frame period data received in the initial downlink period.

Abstract
An apparatus is provided for allocating a transmission period in a wireless network system. An access point (AP) transmits a PSMP frame indicating a downlink period and an uplink period allocated to each station (STA), and at least one sub PSMP frame indicating an allocated downlink period for at least one of a retransmission of downlink data and a transmission of an ACK indicating successful receipt of uplink data. After exchanging data with the AP in the downlink and uplink periods indicated by the PSMP frame, an STA receives the each sub PSMP frame, and performs at least one of a reception of the retransmitted downlink data and a reception of the ACK in the downlink period indicated by the each sub MAP frame.
