摘要： Disclosed is a method for preventing transmission delay occurring when transmitting packet data to a destination in a transmission module including a first memory having a first memory area for storing packet data to be transmitted and a second memory area for backing up the first memory area, a second memory connected to a transmission link, and a frame processor. The method comprises storing a copy of the packet data stored in the second memory area according to a state of the second memory; deleting the packet data stored in the second memory area if copy of the packet data stored in the second memory is transmitted; determining whether packet data combining is possible according to a state of the second memory area; and if the packet data combining is possible, combining the packet data stored in the first memory area with the packet data stored in the second memory area and storing the combined packet data in the second memory.

摘要： A method and system for controlling the transmission power of a terminal transmitting frames in a wireless communication system, the frames having a frame structure including a header field containing information related to a transmission rate and length of data transmitted in a frame and a data field having the data. The transmitting terminal transmits the header field to a receiving terminal at a maximum transmit power level available to the transmitting terminal so that second terminals other than the transmitting terminal and the receiving terminal within the wireless communication system can identify that resources are in use. The transmitting terminal transmits the data field at an optimum transmit power level great enough to allow the data field to reach the receiving terminal.

摘要： The present invention relates to a power saving in a wireless local area network including a plurality of access points providing at least one mobile station in each access point cell boundary with access service, the mobile station transits between an active mode and an idle mode. The power saving method includes grouping the access points into at least one paging group with a paging group boundary; determining if the a mobile station is in the idle mode in which the mobile station switches between an awake state and a doze state every predetermined time interval, or the active mode in which the mobile station is in the awake mode; and if the mobile station is in the idle mode enabling an idle handoff which occurs only when the mobile station crosses the paging group boundary. In the present invention, the handoff occurs when the mobile terminal crosses the paging group boundary but not the access point cell in the idle mode, resulting in reduction of power consumption.

摘要： A method for selecting an antenna in an orthogonalized spatial multiplexing system. Upon receipt of at least one symbol from a transmitter via multiple receive antennas, a receiver decodes each of the received symbols; determines a rotation angle between the received symbols, and selects an optimal subset of transmit antennas using a distance between vectors of the decoded symbols; generates feedback information including the determined rotation angle and the selected optimal subset, and transmits the generated feedback information to the transmitter. Upon receipt of the feedback information, the transmitter beam-forms an antenna corresponding to the optimal subset depending on the received feedback information, and transmits a data symbol to the receiver. The receiver detects each of data symbols received from the transmitter.

摘要： A method 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.
